Notwithstanding any provision herein to the contrary, once one or more Joint Committees have been disbanded, such disbanded Joint Committee and all Working Groups appointed by such Joint Committee shall be terminated and thereafter (i) any requirement of a Party to provide Information or other materials to such Joint Committee shall be deemed a requirement to provide such Information or other materials to the other Party [***].

2.6Alliance Manager. Each Party shall appoint an individual to act as a single point of contact between the Parties to facilitate the effective exchange of information between the Parties and discuss the performance of this Definitive LRRK2 Agreement (each, an “Alliance Manager”).

Each Alliance Manager may have additional responsibilities as agreed between the Parties. [***]

2.7Working Groups. From time to time, a Joint Committee may establish and delegate duties to sub-committees or directed teams (each, a “Working Group”) to oversee particular projects or activities (for example, the Finance Working Group and CMC Working Group), provided that in no event shall a Joint Committee have the right to, and no Joint Committee shall, delegate its respective decision-making authority to any such Working Group. Each such Working Group shall be constituted as the applicable Joint Committee determines and shall establish its own procedures, to the extent that such procedures are consistent with this Definitive LRRK2 Agreement. Members of a Working Group may also be members of a Joint Committee.

Working Group for resolution in accordance with Section 2.4.5 (Joint Committee Decision-Making). Personnel of either Party (or a Party’s Affiliate) that are not representatives of such Party on a Working Group may attend meetings of such Working Group; provided that the Party wishing such persons to participate in a meeting has provided reasonable advance notice to the other Party and non-employees may only attend meetings of a Working Group if such non-employee is bound by written obligations of confidentiality and non-disclosure substantially equivalent to those set forth in Article 10 (Confidentiality and Non-Disclosure) or is otherwise bound by professional ethical obligations. Unless the Parties otherwise agree, draft minutes of the meetings of any Working Group will be generated and circulated to its members within [***] following the meeting. The responsibility for generating and circulating any such minutes will alternate between the Alliance Managers (or their designees). The Working Groups will use diligent efforts to review and finalize any such minutes within [***] after their circulation and, in all circumstances, no later than the next meeting of the same Working Group.

2.8Expenses. Each Party shall be responsible for all travel and related costs and expenses for its representatives and, if applicable, its (or any of its Affiliate’s) other personnel to prepare for, attend meetings of, and otherwise participate in, a Joint Committee or other Working Group.

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

7.10.4BIG will pay the milestone payments for PD Commercial Milestone Events and Non-PD Commercial Milestone Events that are achieved outside of the U.S. when such amounts become due and payable in accordance with Section 7.2.2 (PD Commercial Milestone Payments) and Section 7.3.2 (Non-PD Commercial Milestone Payments). BIMA will pay the milestone payments for PD Commercial Milestone Events and Non-PD Commercial Milestone Events that are achieved in the U.S. when such amounts become due and payable in accordance with Section 7.2.2 (PD Commercial Milestone Payments) and Section 7.3.2 (Non-PD Commercial Milestone Payments).

7.11Taxes.

7.11.1General. Each Party will be responsible for all Taxes imposed on such Party’s net income, or on net income allocated to such Party under Applicable Law. To the extent one Party pays Taxes imposed on net income of the other Party, the other Party shall reimburse the paying Party for any such Taxes paid. The amounts payable pursuant to this Definitive LRRK2 Agreement (“Payments”) shall not be reduced on account of any Taxes unless required by Applicable Law. A payor Party shall deduct and withhold from the Payments any Taxes that it is required by Applicable Law to deduct or withhold including from subsequent Payments. Notwithstanding the foregoing, if the recipient Party is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, or recovery of, applicable withholding tax, it may deliver to the payor Party or the appropriate governmental authority the prescribed forms necessary to reduce the applicable rate of withholding or to relieve the payor Party of its obligation to withhold tax. In such case the payor Party shall apply the reduced rate of withholding, or not withhold, as the case may be, provided that the payor Party is in receipt of evidence, in a form reasonably satisfactory to the payor Party of the recipient Party’s entitlement to a reduced or no withholding rate. If, in accordance with the foregoing, a payor Party withholds any amount, it shall pay to the recipient Party the balance when due, make timely payment to the proper taxing authority of the withheld amount, and send the recipient Party proof of such payment within [***] following that payment. The Parties shall use reasonable efforts to reduce any withholding required under Applicable Law. The Parties hereto agree that as of the date hereof, no U.S. or Swiss withholding taxes are required on the upfront payment described in Section 7.1 (Upfront Payment) under Applicable Law [***].

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

7.11.2Assignment. If a Party that owes a Payment assigns its rights and obligations to any person as permitted in accordance with Section 14.3 (Change of Control; Assignment) of this Definitive LRRK2 Agreement (or any successor provision) and if, solely as a result of such assignment, the withholding of taxes required by Applicable Law with respect to the Payments is increased, then any Payments shall be increased to take into account such withheld taxes so that, after making all required withholding tax (including withholding tax on amounts payable pursuant to Section 7.11.1 (General)), the recipient Party receives an amount equal to the sum it would have received had no such assignment been made.

7.11.3VAT.

(a)All payments or amounts due under this Definitive LRRK2 Agreement, whether monetary or non-monetary are exclusive of VAT. Any Party receiving a supply under this Definitive LRRK2 Agreement hereby covenants that it will pay any such VAT correctly charged in addition to any amounts due under this Definitive LRRK2 Agreement. Where the prevailing legislation requires the recipient to self-account for VAT (for example, but not limited to, the reverse charge mechanism), then the receiving Party covenants that it shall correctly account for VAT in respect of the services received. The supplying Party agrees that it will raise a tax invoice (or equivalent document) to support the charge to VAT.

(b)For the purposes of VAT, the services, rights and licenses provided by Denali under this Definitive LRRK2 Agreement shall be considered to be taxed under by Art 44 of Council Directive 2006/112/EC or any equivalent provision in the country of performance if performed outside the European Union and as such will be considered to be taxed for VAT purposes in the country of the recipient. For the purposes of this clause, BIG warrants that it is established in Switzerland for the purposes of receiving any such services, rights or licenses.

(c)Any supply of goods under this Definitive LRRK2 Agreement shall be taxed in accordance with the prevailing VAT legislation. All Parties agree that they will reasonably cooperate to ensure the use of any VAT exemptions, zero-ratings, reduced-ratings, suspensions or other reliefs.

(d)In the event that the local competent tax authority determines that VAT is chargeable, Denali in the first instance shall undertake all reasonable steps to refute any such assertions by the local tax authority. Only once this process is completed should Denali raise valid tax invoices for the additional VAT liability.

(e)The Parties shall take all reasonable steps to recover any additional VAT liability from the same local tax authorities by submitting regular claims (for example, through periodical VAT returns and discrete non-resident claims such as 8th Directive claims, 13th Directive claims and non-EU equivalents) and shall use commercially reasonable efforts to provide necessary assistance to facilitate the recovery of VAT. If the VAT cannot be recovered, then the supplying Party shall be entitled to invoice the receiving Party directly for these amounts.

(f)Each Party shall be responsible for any penalties or interest accruing due to incorrect VAT treatment of the supplies of goods or services made by that Party or any failure to correctly account for VAT on any receipt of a supply of goods or services under this Definitive LRRK2 Agreement except where those penalties or interest arise as a result of the actions of the other Party, in which case that Party shall be liable to reimburse the value of the penalties and interest.

(g)Each Party shall be responsible for reporting its own transactions to the local tax authorities if required for VAT purposes. There shall be no shared, mutual or otherwise collective VAT filings that may suggest that the Parties are anything other than separately operational entities for VAT purposes.

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

7.11.4Orphan Credit. Denali shall cooperate with Biogen in seeking any tax exemption or credits that may be available to Biogen with respect to any Licensed Compound, including the tax credit available under section 45C of the Internal Revenue Code by reason of Biogen’s research and development expenditures contributing to the any compound under thisDefinitive LRRK2 Agreement being granted Orphan Drug status by the FDA. Notwithstanding any provision to the contrary set forth in this Definitive LRRK2 Agreement, Denali accepts no responsibility for, and expressly disclaims all liability arising from, Biogen’s failure to qualify for any tax exemptions or credits for any reason.

7.11.5[***]

7.12Interest on Late Payments. If any payment or portion thereof due to either Party under this Definitive LRRK2 Agreement is not paid when due, then such paying Party shall pay interest thereon at a rate equal to [***] or, if lower, the maximum rate permitted by Applicable Law.

7.13Financial Records. Each Party shall keep complete and accurate books and records pertaining to Net Sales of Licensed Products, Eligible Development Expenses, Allowable Expenses and Net Revenues with respect to the Licensed Compounds and Licensed Products, and Development of the Licensed Compounds or Licensed Products, including books and records of actual expenditures with respect to the Global Development Budget and the Co-Commercialization Budget, in sufficient detail to calculate all amounts payable hereunder and to verify compliance with its obligations under this Definitive LRRK2 Agreement. Such books and records shall be retained by such Party until the later of (a) [***] after the end of the period to which such books and records pertain, and (b) the expiration of the applicable tax statute of limitations (including any extensions thereof), or for such longer period as may be required by Applicable Law.

7.14Audit. At the request of the other Party, each Party shall permit an independent public accounting firm of nationally recognized standing designated by the other Party and reasonably acceptable to the audited Party, at reasonable times during normal business hours and upon reasonable notice, to audit the books and records maintained pursuant to Section 7.13 (Financial Records) to ensure the accuracy of all financial reports and notices delivered and payments made hereunder. Such examinations may not (a) be conducted for any Calendar Year more than [***] after the end of such Calendar Year, (b) be conducted more than once in any Calendar Year or (c) be repeated for any audited period; except for cause. The accounting firm shall disclose to the auditing Party whether the reports are correct or not, and the details concerning any discrepancies sufficient for the auditing Party to understand any such discrepancies. Except as provided below, the cost of this audit shall be borne by the auditing Party, unless the audit reveals a variance of greater than [***] from the reported amounts for the inspected period, in which case the audited Party shall bear the cost of the audit. If such audit concludes that (i) additional amounts were owed by the audited Party, the audited Party shall pay the additional undisputed amounts, with interest from the date originally due as provided in Section 7.12 (Interest on Late Payments), or (ii) excess payments were made by the audited Party, the auditing Party shall, at its election, reimburse such undisputed excess payments or elect that such excess payments shall be offset against future payments due to the auditing Party under this Definitive LRRK2 Agreement, in either case ((i) or (ii)), within [***] after the date on which such audit is completed by the auditing Party. Any disputes with respect to the findings of such accounting firm may be referred by either Party to the dispute resolution procedure set forth in Section 14.6 (Dispute Resolution). The auditing Party will treat all financial information disclosed by its accounting firm pursuant to this Section 7.14 (Audit) as Confidential Information of the audited Party for purposes of Article 10 (Confidentiality and Non-Disclosure) of this Agreement, and will cause its accounting firm to do the same.

7.15Confidentiality. The receiving Party shall treat all information subject to review under this Article 7 (Payments) in accordance with the confidentiality provisions of Article 10 (Confidentiality and Non-Disclosure) and the Parties shall enter into a reasonably acceptable confidentiality agreement with the independent accountant obligating such accountant to retain all such financial information in confidence pursuant to such confidentiality agreement.

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

7.16No Other Compensation. Each Party hereby agrees that the terms of this Definitive LRRK2 Agreement fully define all consideration, compensation and benefits, monetary or otherwise, to be paid, granted or delivered by a Party to the other Party in connection with the transactions contemplated herein. Neither Party previously has paid or entered into any other commitment to pay, whether orally or in writing, any of the other Party’s employees, directly or indirectly, any consideration, compensation or benefits, monetary or otherwise, in connection with the transaction contemplated herein.

The terms, but not the mere existence, of this Definitive LRRK2 Agreement will also be considered Confidential Information for which each Party is a receiving Party for purposes of this Article 10(Confidentiality and Non-Disclosure). Notwithstanding the foregoing, the confidentiality and non-use obligations under this Section 10.1 (Confidentiality Obligations) shall not apply to any information that the receiving Party can demonstrate by documentation or other competent proof:

except in the case of clauses (a) through (c), to the extent of those Indemnified Losses for which Denali, in whole or in part, has an obligation to indemnify Biogen pursuant to Section 12.2 (Indemnification of Biogen) hereof, as to which Indemnified Losses each Party shall indemnify the other to the extent of their respective liability for such Indemnified Losses.

12.2Indemnification of Biogen.

12.3Certain Indemnified Losses. Any Indemnified Losses and all Out-of-Pocket Costs incurred by a Party to conduct its indemnification obligations under Section 12.1 (Indemnification of Denali) or 12.2 (Indemnification of Biogen), (other than those Indemnified Losses and Out-of-Pocket Costs that result from (a) [***], in connection with any Third Party Claim brought against either Party resulting directly or indirectly from (i) [***] or (ii) [***].

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

12.5Control of Defense.

12.5.1In General. Subject to the provisions of Section 8.4 (Infringement Claims by Third Parties), Section 8.5 (Invalidity or Unenforceability Defenses or Actions), and 8.6.3 (Third Party Claims) and Section 12.3 (Certain Indemnified Losses) above,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 (In General), the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party that must 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.

12.5.2Right 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.

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

12.5.3Settlement. 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 or other relief 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, then 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.

12.5.4Cooperation. 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 Costs in connection therewith.

12.6Special, Indirect and Other Losses. EXCEPT (A) [***], (B) [***] AND (C) TO [***], 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 DEFINITIVE LRRK2 AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE USE OF A LICENSED COMPOUND OR LICENSED PRODUCT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

12.7Insurance. 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 Licensed 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 Study insurance must be implemented by the sponsor of the Clinical Study 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 Definitive LRRK2 Agreement. Notwithstanding the foregoing, Biogen may self-insure, in whole or in part, the insurance requirements described above, provided that Biogen is and continues to be investment grade as determined by reputable and accepted financial rating agencies.

13.10.1All rights and licenses now or hereafter granted by one Party to the other Party under or pursuant to this Definitive LRRK2 Agreement are, for all purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined in the U.S. Bankruptcy Code. Upon the filing or institution of bankruptcy, reorganization, liquidation, or receivership proceedings, upon the appointment of a receiver or trustee over all or substantially all property, or upon an assignment of a substantial portion of the assets for the benefit of creditors by a Party, such Party agrees that the other Party, as licensee of such rights under this Definitive LRRK2 Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. Each Party will, during the Term, create and maintain current copies or, if not amenable to copying, other appropriate embodiments, to the extent feasible, of all intellectual property rights licensed under this Definitive LRRK2 Agreement. Each Party acknowledges and agrees that “embodiments” of intellectual property rights within the meaning of Section 365(n) include laboratory notebooks, cell lines, product samples, and inventory, research studies and data, all Regulatory Approvals (and all applications for Regulatory Approval) and rights of reference therein, in each case, to the extent licensed by a Party to the other Party hereunder, as well as the Denali IP and the Biogen IP (as the case may be), and all information related to the Denali IP and the Biogen IP (as the case may be). If (x) a case under the U.S. Bankruptcy Code is commenced by or against the debtor Party, (y) this Definitive LRRK2 Agreement is rejected as provided in the U.S. Bankruptcy Code, and (z) the non-debtor Party elects to retain its rights hereunder as provided in Section 365(n) of the U.S. Bankruptcy Code, then the debtor Party (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will:

(a)provide the non-debtor Party with all such intellectual property rights (including all embodiments thereof) licensed hereunder and held by the debtor Party and such successors and assigns, or otherwise available to them, immediately upon the non-debtor Party’s written request. Whenever the debtor Party or any of its successors or assigns provides to the non-debtor Party any of the intellectual property rights licensed hereunder (or any embodiment thereof) pursuant to this Section 13.10 (Rights in Bankruptcy), the non-debtor Party will have the right to perform the debtor Party’s obligations hereunder with respect to such intellectual property rights, but neither such provision nor such performance by the non-debtor Party will release the debtor Party’s from liability resulting from rejection of the license or the failure to perform such obligations; and

(b)not interfere with the non-debtor Party’s rights under this Definitive LRRK2 Agreement, or any agreement supplemental hereto, with respect to such intellectual property rights (including such embodiments), including any right to obtain such intellectual property rights (or such embodiments) from another entity, to the extent provided in Section 365(n) of the U.S. Bankruptcy Code.

13.10.2All rights, powers and remedies of the non-debtor Party provided in this Section 13.10 (Rights in Bankruptcy) are in addition to and not in substitution for any other rights, powers, and remedies now or hereafter existing at law or in equity (including the U.S. Bankruptcy Code) in the event of the commencement of a case under the U.S. Bankruptcy Code with respect to the debtor Party. The Parties intend the following rights to extend to the maximum extent permitted by Applicable Law, and to be enforceable under U.S. Bankruptcy Code Section 365(n):

(a)the right of access to any intellectual property rights (and all embodiments thereof) of the debtor Party licensed hereunder, or any Third Party with whom the debtor Party contracts to perform any obligation of the debtor Party under this Definitive LRRK2 Agreement, and, in the case of any such Third Party, that is necessary for the Exploitation of Licensed Products and licensed hereunder; and

(b)the right to contract directly with any Third Party to complete the contracted work.

Neither Party will be held liable to the other Party nor be deemed to have defaulted under or breached this Definitive LRRK2 Agreement for failure or delay performing any obligation under this Definitive LRRK2 Agreement to the extent that such failure or delay is caused by or results from acts of God, embargoes, war, acts of war (whether war be declared or not), terrorism, insurrections, riots, civil commotions, strikes, lockouts, or other labor disturbances (other than strikes, lockouts, or labor disturbances involving a Party’s own employees), government actions, fire, earthquakes, floods, [***](“Force Majeure”) beyond such Party’s reasonable control, and renders the performance impossible or illegal. [***] The affected Party will notify the other Party in writing of any Force Majeure circumstances that may so affect its performance under this Definitive LRRK2 Agreement as soon as reasonably practical (but in any event within [***] after such Force Majeure occurrence), will provide a good faith estimate of the period for which its failure or delay in performance under this Definitive LRRK2 Agreement is expected to continue based on currently available information, and will undertake reasonable efforts necessary to mitigate and overcome such Force Majeure circumstances and resume normal performance of its obligations hereunder as soon a reasonably practicable under the circumstances. If the Force Majeure circumstance continues, then the affected Party will update such notice to the other Party on a [***] basis to provide updated summaries of its mitigation efforts and its estimates of when normal performance under this Definitive LRRK2 Agreement will be able to resume.

14.2Export Control. This Definitive LRRK2 Agreement is made subject to any restrictions concerning the export of products or technical information from the United States or other countries that may be imposed on the Parties from time to time. Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under this Definitive LRRK2 Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate agency or other governmental entity in accordance with Applicable Law.

14.3Change of Control; Assignment.

14.3.1Without the prior written consent of the other Party, neither Party shall sell, transfer, assign, delegate (except as expressly permitted under this Definitive LRRK2 Agreement), pledge, or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Definitive LRRK2 Agreement or any of its rights or duties hereunder; provided, that (a) either Party may make such an assignment without the other Party’s consent to: (i) [***] or (ii) [***]. [***] Any attempted assignment or delegation in violation of this Section 14.3 (Change of Control; Assignment) shall be void and of no effect. All validly assigned and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the benefit of and be enforceable by and against the successors and permitted assigns of Denali or Biogen, as the case may be. The permitted assignee or transferee shall assume all obligations of its assignor or transferor under this Definitive LRRK2 Agreement. Without limiting the foregoing, the grant of rights set forth in this Definitive LRRK2 Agreement shall be binding upon any successor or permitted assignee of a Party, and the obligations of the other Party, including the payment obligations, shall run in favor of any such successor or permitted assignee of such Party’s benefits under this Definitive LRRK2 Agreement.

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

14.4Severability. If any provision of this Definitive LRRK2 Agreement is held to be illegal, invalid, or unenforceable under any present or future law, and if the rights or obligations of either Party under this Definitive LRRK2 Agreement will not be materially and adversely affected thereby, then: (a) such provision shall be fully severable; (b) this Definitive LRRK2 Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof; (c) the remaining provisions of this Definitive LRRK2 Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom; and (d) in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Definitive LRRK2 Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties. In the event a Party seeks to avoid a provision of this Definitive LRRK2 Agreement by asserting that such provision is invalid, illegal or otherwise unenforceable, the other Party shall have the right to terminate this Definitive LRRK2 Agreement upon [***] prior written notice, unless such assertion is eliminated and its effect is cured within such [***] period. Any such termination in accordance with this Section 14.4 (Severability) with respect to as assertion by a Party shall be deemed a termination for breach by such Party pursuant to Section 13.2 (Termination for Material Breach). To the fullest extent permitted by Applicable Law, each Party hereby waives any provision of law that would render any provision hereof illegal, invalid, or unenforceable in any respect.

14.5Governing Law, Jurisdiction and Service.

14.5.1Governing Law. This Definitive LRRK2 Agreement or the performance, enforcement, breach or termination hereof shall be interpreted, governed by and construed in accordance with the laws of the State of [***], United States, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Definitive LRRK2 Agreement to the substantive law of another jurisdiction; provided, that all questions concerning: (a) determination of whether Information and inventions are conceived, discovered, developed or otherwise made by a Party for the purpose of allocating proprietary rights (including Patent, copyright or other intellectual property rights) therein, shall, for purposes of this Definitive LRRK2 Agreement, be made in accordance with Applicable Law in the United States; and (b) the construction or effect of Patents shall be determined in accordance with the laws of the country or other jurisdiction in which the particular Patent has been filed or granted, as the case may be. The Parties agree to exclude the application to this Definitive LRRK2 Agreement of the United Nations Convention on Contracts for the International Sale of Goods.

14.5.2Each Party further agrees that service of any process, summons, notice or document by registered mail to its address set forth in Section 14.7 (Notices) shall be effective service of process for any action, suit, or proceeding brought against it under this Definitive LRRK2 Agreement in any such court.

14.6Dispute Resolution. Except for disputes resolved by the procedures set forth in Section 2.4.5 (Joint Committee Decision-Making) or 14.10 (Equitable Relief) or for which Biogen has final decision-making authority as provided in Section 2.4.5(c) (Dispute Escalation), if a dispute arises between the Parties in connection with or relating to this Definitive LRRK2 Agreement or any document or instrument delivered in connection herewith or the breach, termination, enforcement, interpretation or validity hereof (a “Dispute”), then it shall be resolved pursuant to this Section 14.6 (Dispute Resolution). For the avoidance of doubt, any suit, action or other proceeding arising out of or based upon the Stock Purchase Agreement shall be subject to resolution in accordance with Section 9.13 of the Stock Purchase Agreement and any suit, action or other proceeding arising out of or based upon the Standstill Agreement shall be subject to resolution in accordance with Section 7(d) of the Standstill Agreement.

14.6.1General. Any Dispute shall first be referred to the Biogen Executive and the Chief Executive Officer of Denali (or his/her executive-level designee) (the “Chief Executive Officers”), who shall confer in good faith on the resolution of the issue. Any final decision agreed to by the Chief Executive Officers shall be conclusive and binding on the Parties. If the Chief Executive Officers are not able to agree on the resolution of any such issue within [***] (or such other period of time as mutually agreed by the Chief Executive Officers) after such issue was first referred to them, then [***]

14.6.2Intellectual Property Disputes. In the event that a Dispute arises with respect to the validity, scope, enforceability, inventorship or ownership of any Patent, Trademark or other intellectual property rights, and such Dispute cannot be resolved in accordance with Section 14.6.1 (General), either Party may initiate litigation in a court of competent jurisdiction, notwithstanding Section 14.5 (Governing Law, Jurisdiction and Service), in any country or other jurisdiction in which such rights apply.

14.6.3Jurisdiction. Each of the Parties hereby submits to the jurisdiction of the [***] in any proceeding arising out of or relating to this Agreement, agrees not to commence any suit, action or proceeding relating thereto except in such court, and waives, to the fullest extent permitted by Applicable Law, the right to move or dismiss or transfer any action brought in such court on the basis of any objection to personal jurisdiction, venue or inconvenient jurisdiction. Any rights to trial by jury with respect to any suit, action, proceeding or claim (whether based upon contract, tort or otherwise), directly or indirectly, arising out of or relating to this Agreement hereunder are expressly and irrevocably waived by each of the Parties.

14.6.4Disputes Regarding LRRK2 Inhibitor or CNS Penetrant. In the event of a Dispute as to whether [***], then, either Party may, on written notice to the other Party, refer such matter to an independent Third Party laboratory, acceptable to the other Party (such acceptance not to be unreasonably withheld, conditioned or delayed) (“Independent Third Party Lab”). Such Independent Third Party Lab shall perform [***]. The conclusions of the Independent Third Party Lab shall be final and binding on the Parties and the Parties shall share equally the costs of any Independent Third Party Lab engaged by a Party pursuant to this Section 14.6.4 (Disputes Regarding LRRK2 Inhibitor or CNS Penetrant).

14.8Entire Agreement; Amendments. This Definitive LRRK2 Agreement, together with the Schedules attached hereto, sets forth and constitutes the entire agreement and understanding between the Parties with respect to the subject matter hereof and all prior agreements, understandings, promises, and representations, whether written or oral, with respect thereto are superseded hereby (including that certain Prior CDA and the aspects of the Provisional Collaboration and License Agreement pertaining to Licensed Compounds and Licensed Products). Each Party confirms that it is not relying on any representations or warranties of the other Party except as specifically set forth in this Definitive LRRK2 Agreement. Except for amendments and modifications to the Global Development Plan/Budget, and Commercialization Plans in accordance with Article 2 (Collaboration Management), Section 3.1.2 (Amendments and Updates), Section 3.1.4(e)(iv) (Independent Study Opt-In Notice) and Section 5.2.4 (Amendments and Updates), no amendment, modification, release, or discharge shall be binding upon the Parties, unless in writing and duly executed by authorized representatives of both Parties.

14.9English Language.

14.10Equitable Relief. Notwithstanding any provision herein to the contrary, nothing in Section 14.6 (Dispute Resolution) shall preclude either Party from seeking interim or provisional relief, including a temporary restraining order, preliminary injunction or other interim equitable relief concerning a Dispute, if necessary to protect the interests of such Party. This Section 14.10 (Equitable Relief) shall be specifically enforceable. Additionally, each Party acknowledges and agrees that the restrictions set forth in [***] are reasonable and necessary to protect the legitimate interests of the other Party and that such other Party would not have entered into this Definitive LRRK2 Agreement in the absence of such restrictions, and that any breach or threatened breach of any provision of such Section or Articles may result in irreparable injury to such other Party for which there may be no adequate remedy at law. In the event of an actual or threatened breach of any provision of such Sections or Article, or other default or non-performance with respect to such Section or Article, the aggrieved Party may seek equitable relief (including restraining orders, specific performance or other injunctive relief) in any court or other forum, without first submitting to the dispute resolution procedures set forth in Section 14.6 (Dispute Resolution). Nothing in this Section 14.10 (Equitable Relief) 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 Definitive LRRK2 Agreement.

14.11Waiver and Non-Exclusion of Remedies. Any term or condition of this Definitive LRRK2 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.

14.12No Benefit to Third Parties. Except as provided in Article 12 (Indemnity; Limitations of Liability; Insurance) and Section 6.5.1 (Existing Denali Agreements), covenants and agreements set forth in this Definitive LRRK2 Agreement are for the sole benefit of the Parties hereto and successors and permitted assigns of the Parties, and shall not be construed as conferring any rights on any other Persons.
