All amounts listed in are in U.S. Dollars. For clarity, the total amount payable to Takeda under this Section 8.2 if all sales milestone events are achieved is $[***].

In the event two (2) or more Net Sales Milestone events are achieved in the same Calendar Year, Licensee shall pay to Takeda each milestone payment corresponding to the respective milestone event.

8.5    Royalty Reduction for Generic Competition. Subject to the limitation set forth in Section 8.8, the royalty rates set forth in Section 8.3 for Net Sales in such country (after any previous reduction(s), if any, made pursuant to Section 8.6) shall be reduced, on a country-by-country basis by [***] percent ([***]%)] at the end of the first to occur Calendar Quarter during which the Generic Competition Percentage in such country of the Territory during such time period is greater than or equal to [***] percent ([***]%)].

8.6    Royalty Reduction for Patent Expiry. Subject to the limitation set forth in Section 8.8, during the Royalty Term with respect to any Product being Commercialized in the United States, following expiration of the last to expire Valid Claim in a Takeda Patent published in the FDA’s Orange Book, the royalty rates for such Product set forth in Section 8.3 for Net Sales (after any previous reduction(s), if any, made pursuant to this Section 8.5) shall be reduced by [***] percent ([***]%) of such royalty rates until the end of the Royalty Term.

8.7    Payment for Third Party Licenses.

(a)    During the Term, Licensee will have the right, following reasonable consultation with Takeda, to negotiate and obtain a license under one or more Patents (other than any license granted in settlement of any litigation as contemplated under Section 9.6) from one or more Third Parties (each such Third Party license is referred to herein as a “Third Party License”) if in the absence of a license under such Third Party Patents, the Exploitation of the applicable Compound or Product in the Field in the Territory in a manner consistent with Licensee’s obligation to use Commercially Reasonable Efforts to Develop and Commercialize the Compound and the Product under this Agreement would, in Licensee’s good faith assessment, upon advice of legal counsel, infringe such Third Party Patents. Except as set forth in Section 8.7(c) or to the extent of any Claim for which Takeda provides indemnification under Section 15.2, or as the Parties may otherwise agree in writing, Licensee shall bear any payments associated with any royalties owed to any Third Party for such a Third Party License (collectively, the “Third Party Royalties”).

(b)    In the event that Takeda disputes Licensee’s determination that any Third Party Royalties are properly subject to the royalty offset provided under this Section 8.7 or Licensee’s allocation of any such Third Party Royalties to a Product, Takeda may by written notice to Licensee require that such dispute be resolved in accordance with Article 14; provided that Licensee shall have the right to take royalty reductions pursuant to this Section 8.7 pending resolution of any such dispute; provided further, that if any such dispute is resolved in favor of Takeda, then within [***] of such resolution, Licensee shall pay to Takeda any adjustment in royalties due pursuant to this Section 8.7 as required by such resolution.

(c)    Subject to the limitation set forth in Section 8.8, Licensee may credit up to [***] percent ([***]%)] of the amount of any Third Party Royalties paid by Licensee under a Third Party License pursuant to Section 8.7(a), or paid under any license granted in settlement of any claim of infringement of any Third Party claim of infringement under Section 9.6, against royalties payable to Takeda under Section 8.3.

royalties are payable hereunder; provided, that in no event will such credit reduce the royalties payable to Takeda for such Calendar Quarter by more than [***] percent ([***]%).

(d)    This Section 8.7 shall not apply to any Third Party Royalties payable by Licensee or any of its Affiliates or sublicensees under any license or other agreement or understanding, written or oral, between Licensee or any of its Affiliates or sublicensees, on the one hand, and any Third Party, on the other hand, in existence as of the Effective Date.

8.8    Limitation on Royalty Reductions. Notwithstanding anything contained in this Agreement to the contrary, the reductions and offsets to royalties provided in Sections 8.5, 8.6, and 8.7 may not, individually or in the aggregate, reduce the royalties payable with respect to Net Sales of any Product sold by Licensee, its Affiliates and its and their sublicensees in any country during a Calendar Quarter during the Royalty Term by more than [***] from the original royalty percentage amount owed to Takeda pursuant to Section 8.3 (i.e.; the [***] royalties could at most be reduced respectively to be [***] royalties on Net Sales).

Within [***], Licensee shall provide Takeda with a report containing the actual (not estimated) information described above in respect of such [***] for Takeda’s review and confirmation within [***] from receipt. In the event that either party determines that the calculation of Net Sales for a [***] deviates from the amounts previously reported to Takeda for any reason (such as, on account of additional amounts collected or Product returns), Licensee and Takeda shall reasonably cooperate to reconcile any such deviations to the extent necessary under applicable legal or financial reporting requirements. Within the later of (a) [***], or (b) [***] following Takeda’s written confirmation of the applicable [***] report, Licensee shall pay all amounts due to Takeda pursuant to this Article 8 with respect to Net Sales for such Calendar Quarter.

(b)    Tax Residence Certificate. A Party receiving a payment pursuant to this Article 8 shall provide the remitting Party appropriate certification from relevant revenue authorities that such Party is a tax resident of a jurisdiction, if such receiving Party wishes to claim the benefits of an income tax treaty to which that jurisdiction is a party. Upon the receipt thereof, any deduction and withholding of Taxes shall be made at the appropriate treaty tax rate.

(c)    Assessment. Either Party may, at its own expense, protest any assessment, proposed assessment, or other claim by any Governmental Authority for any additional amount of taxes, interest or penalties or seek a refund of such amounts paid if permitted to do so by Applicable Law.

If Licensee assigns its rights and obligations hereunder to an Affiliate or Third Party in compliance with Section 16.4 and if such Affiliate or Third Party shall be required by Applicable Law to withhold any additional Taxes from or in respect of any amount payable under this Agreement as a result of such assignment, then any such amount payable under this Agreement shall be increased to take into account the additional Taxes withheld as may be necessary so that, after making all required withholdings, Takeda receives an amount equal to the sum it would have received as of the Effective Date For the avoidance of doubt, if Takeda assigns its right and obligations under this Agreement in compliance with Section 16.4, Takeda shall not be entitled to any additional payments with respect to Taxes arising as a result of Takeda’s assignment.

Each Party agrees that, during the Term and for a period of [***] thereafter, a Party (the “Receiving Party”) receiving Confidential Information of the other Party (the “Disclosing Party”) shall (a) maintain in confidence such Confidential Information using not less than the efforts such Receiving Party uses to maintain in confidence its own confidential or proprietary information of similar kind and value, (b) not disclose such Confidential Information to any Third Party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted below, and (c) not use such Confidential Information for any purpose except those permitted by this Agreement (it being understood that this Section 11.1 shall not create or imply any rights or licenses not expressly granted under this Agreement). Notwithstanding anything to the contrary in the foregoing, the obligations of confidentiality and non-use with respect to any trade secret (to the extent understood by a Party to be a trade secret) within such Confidential Information shall survive such [***] period for so long as such Confidential Information remains protected as a trade secret under Applicable Law.

11.2    Exceptions. The obligations in Section 11.1 shall not apply with respect to any portion of the Confidential Information that the Receiving Party can show by competent evidence:

(g)    If and whenever any Confidential Information is disclosed in accordance with this Section 11.3, such disclosure shall not cause any such information to cease to be Confidential Information except to the extent that such disclosure results in a public disclosure of such information (other than by breach of this Agreement). Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information pursuant to clauses (a) through (d) of this Section 11.3, it shall, except where impracticable, give reasonable advance notice to the other Party of such disclosure and use not less than the same efforts to secure confidential treatment of such information as it would to protect its own confidential information from disclosure and shall be jointly and severally liable for any breach of this Article 11 by such Person.

No such notice shall be required if the description of or reference to this Agreement or a related agreement between the Parties contained in the proposed filing has been included in any previous filing made by the either Party in accordance with this Section 11.6 or otherwise approved by the other Party or disclosed in a prior press release by the Parties or other prior public disclosure made by a Party in accordance with the terms of this Article 11.

11.7    Publications and Promotional Materials.

The Review Period may be extended for an additional [***] in the event such receiving Party can, within [***] of receipt of the written copy, demonstrate reasonable need for such extension including for the preparation and filing of patent applications. Each Party shall comply, and shall cause its Affiliates and sublicensees to comply, with (i) standard academic practice regarding authorship of scientific publications and recognition of contribution of the other Party in any publication governed by this Section 11.7, including International Committee of Medical Journal Editors standards regarding authorship and contributions, and (ii) standard pharmaceutical industry accepted guidelines regarding promotional materials, including Pharmaceutical Research and Manufacturers of America (PhRMA) guidelines.

11.8    Equitable Relief. Given the nature of the Confidential and the competitive damage that could result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach of this Article 11. In addition to all other remedies, a Party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this Article 11.

12.2    Sharing of Know-How.

(a)    At one (1) Information Sharing Committee meeting [***], the Information Sharing Committee shall discuss, and in good faith attempt to agree upon, whether (i) any Takeda Know-How first obtained or generated by Takeda after the Effective Date is reasonably necessary or useful to enable Licensee to perform its obligations under this Agreement, and (ii) any Licensee Know-How is reasonably necessary or useful to enable Takeda: (a) to perform its obligations under this Agreement; (b) Develop or Manufacture the Product; and (c) Commercialize the Product outside of the Territory. Takeda shall disclose to Licensee all Takeda Know-How first obtained or generated by Takeda after the Effective Date that the Information Sharing Committee determines is reasonably necessary or useful to enable Licensee to perform its obligations under this Agreement.

(a)    on a country-by-country and Product-by-Product basis, upon the expiration of the Royalty Term with respect to each Product in each country in the Territory, as applicable; or

(a)    Either Party (the “Non-breaching Party”) may terminate this Agreement in its entirety in the event the other Party (the “Breaching Party”) has materially breached this Agreement, and such material breach has not been cured within [***] (other than any breach for failure to pay, which shall be [***] or other than as provided in Section 13.2(b)) after receipt of written notice of such breach by the Breaching Party from the Non-Breaching Party (the “Cure Period”); provided, however, that, to the extent termination is for uncured breach by Licensee, such termination shall apply only to those countries in the Territory to which such breach relates except for an uncured breach affecting the United States, in which case this Agreement will terminate in its entirety. A material breach by Licensee of the Warrant, which is not cured by Licensee within [***] after written notice of such material breach to Licensee from Takeda, shall be deemed a material breach of this Agreement which relates to the entire Territory. The written notice describing the alleged material breach shall provide sufficient detail to put the Breaching Party on notice of such material breach. Any termination of this Agreement pursuant to this Section 13.2(a) shall become effective at the end of the Cure Period, unless the Breaching Party has cured any such material breach prior to the expiration of such Cure Period, or unless such allegedly breaching Party disputes such breach. The right of either Party to terminate this Agreement as provided in this Section 13.2(a) shall not be affected in any way by such Party’s waiver of or failure to take action with respect to any previous breach under this Agreement.

(b)    If the Parties reasonably and in good faith disagree as to whether there has been a material breach, including whether such breach was material, the Party that disputes whether there has been a material breach may contest the allegation in accordance with Article 14.

13.3    Termination by Licensee.

(a)    Licensee shall have the unilateral right to terminate this entire Agreement upon [***] written notice to Takeda.

(b)    Licensee shall have the right to terminate this entire Agreement at any time upon providing [***] prior written notice to Takeda if Licensee determines that the Compound or the Product caused or is likely to cause a fatal, life-threatening or other serious adverse event that is reasonably expected, based upon then available data, to preclude continued Development and/or Commercialization of the Product in the Field in the Territory.

(c)    The Parties may agree to terminate this Agreement prior to expiration of the [***] notice period provided in Section 13.3(b) above, where the Parties: (i) have reached consensus

regarding the inability to continue Commercializing the Products in the Field in the Territory for the reasons set forth in Section 13.3(b); and (ii) have completed all wind-down and other transition activities, including those set forth in Section 13.7.

13.4    Termination for Patent Challenge. Takeda may terminate this entire Agreement at any time upon written notice to Licensee, if Licensee, or any of Licensee’s Affiliates, or its or their sublicensees, directly, or indirectly through assistance granted to a Third Party, commences any interference or opposition proceeding, challenges the validity or enforceability of, or opposes any extension of or the grant of a supplementary protection certificate with respect to (a “Patent Proceeding”) any Takeda Patent or any other Patent owned or controlled by Takeda that claims or discloses the composition of matter or the method of making or using the Product anywhere in the Territory except for a country in the Territory in which this Agreement has been terminated prior to the commencement of any such Patent Proceeding. However, Takeda’s right to terminate this Agreement under this Section 13.4 shall not apply to any Affiliate of Licensee that first becomes an Affiliate of Licensee after the Effective Date in connection with a merger or acquisition event, or any sublicensee, where such Affiliate or sublicensee was undertaking activities in connection with a Legal Proceeding prior to such merger or acquisition event or the grant of such sublicense, provided such Affiliate or sublicensee promptly ceases all activities in the furtherance of such Patent Proceeding and withdraws or terminates with prejudice any such Patent Proceeding within [***] of such merger or acquisition event or grant of sublicense.

13.5    Termination for Insolvency.

(a)    Either Party may terminate this Agreement in its entirety upon providing written notice to the other Party on or after the time that such other Party makes a general assignment for the benefit of creditors, files an insolvency petition in bankruptcy, petitions for or acquiesces in the appointment of any receiver, trustee or similar officer to liquidate or conserve its business or any substantial part of its assets, commences under the laws of any jurisdiction any proceeding involving its insolvency, bankruptcy, reorganization, adjustment of debt, dissolution, liquidation or any other similar proceeding for the release of financially distressed debtors, or becomes a party to any proceeding or action of the type described above, and such proceeding or action remains un-dismissed or un-stayed for a period of more than [***].

(b)    All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of Title 11 of the United States Code and other similar laws in any other jurisdiction outside of the Territory (collectively, the “Bankruptcy Laws”), licenses of rights to “intellectual property” as defined under the Bankruptcy Laws. If a case is commenced during the Term by or against a Party under Bankruptcy Laws then, unless and until this Agreement is rejected as provided pursuant to such Bankruptcy Laws, such Party (in any capacity, including debtor-in-possession) and its successors and assigns (including a Title 11 trustee) shall perform all of the obligations in this Agreement intended to be performed by such Party. If a case is commenced during the Term by or against a Party under the Bankruptcy Laws, this Agreement is rejected as provided for under the Bankruptcy Laws, and the non-bankrupt Party elects to retain its rights hereunder as provided for under the Bankruptcy Laws, then the Party subject to such case under the Bankruptcy Laws (in any capacity, including debtor-in-possession) and its successors and assigns (including a Title 11 trustee), shall provide to the non-bankrupt Party copies of all Patents and Information necessary for the non-bankrupt Party to

prosecute, maintain and enjoy its rights under the terms of this Agreement.

ARTICLE 15 – INDEMNIFICATION AND LIMITATION OF LIABILITY

15.1    Indemnification by Licensee. Licensee hereby agrees to defend, indemnify and hold harmless Takeda and its Affiliates, and each of their respective directors, officers, employees, agents and representatives (each, a “Takeda Indemnitee”) from and against any and all claims, suits, actions, demands, liabilities, expenses and/or loss, including reasonable legal expense and attorneys’ fees (collectively, the “Losses”), to which any Takeda Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party (each, a “Claim”) to the extent such Losses arise directly or indirectly out of: (i) the practice by Licensee or its Affiliate of any license granted to it under Article 4; (ii) the use, handling, storage, sale or other disposition of the Compound or the Product by Licensee or its Affiliate or sublicensee, including any use of the Compound or the Product for Development and Commercialization; (iii) the breach by Licensee of any warranty, representation, covenant or agreement made by Licensee in this

Agreement; or (iv) the negligence, gross negligence or willful misconduct of Licensee, its Affiliate or its sublicensee, or any officer, director, employee, agent or representative thereof; except, with respect to each of subsections (i) through (iv) above, to the extent such Losses arise directly or indirectly from the negligence, gross negligence or willful misconduct of any Takeda Indemnitee or the breach by Takeda of any warranty, representation, covenant or agreement made by Takeda in this Agreement, or are subject to Takeda’s indemnification obligations pursuant to Section 15.2.

15.2     Indemnification by Takeda. Takeda hereby agrees to defend, indemnify and hold harmless Licensee and its Affiliates and each of their respective directors, officers, employees, agents and representatives (each, an “Licensee Indemnitee”) from and against any and all Losses to which any Licensee Indemnitee may become subject as a result of any Claim to the extent such Losses arise directly or indirectly out of: (i) the practice by Takeda or its Affiliate of any license granted to it under Article 4; (ii) the manufacture, use, handling, storage, sale or other disposition of the Compound or the Product (other than the manufacture, use, handling, storage, by Takeda or any of its Affiliates or licensees for any of the Licensee Indemnitees or the sale or other disposition of Compound or Product by Takeda or its Affiliate or its licensee to any of the Licensee Indemnitees) by Takeda or its Affiliate or its licensee (other than Licensee or its Affiliate or sublicensee); (iii) the breach by Takeda of any warranty, representation, covenant or agreement made by Takeda in this Agreement; or (iv) the negligence, gross negligence or willful misconduct of Takeda or its Affiliate or its licensee (other than Licensee or its Affiliate), or any officer, director, employee, agent or representative thereof; except, with respect to each of subsections (i) through (iv) above, to the extent such Losses arise directly or indirectly from the negligence, gross negligence or willful misconduct of any Licensee Indemnitee or the breach by Licensee of any warranty, representation, covenant or agreement made by Licensee in this Agreement, or are subject to Licensee’s indemnification obligations pursuant to Section 15.1.

15.3    Indemnification Procedures.

(a)    Notice. Promptly after a Takeda Indemnitee or a Licensee Indemnitee (each, an “Indemnitee”) receives notice of a pending or threatened Claim, such Indemnitee shall give written notice of the Claim to the Party from whom the Indemnitee is entitled to receive indemnification pursuant to Sections 15.1 or 15.2, as applicable (the “Indemnifying Party”). However, an Indemnitee’s delay in providing or failure to provide such notice shall not relieve the Indemnifying Party of its indemnification obligations, except to the extent it can demonstrate prejudice due to the delay or lack of notice.

(b)    Defense. Upon receipt of notice under Section 15.3(a) from the Indemnitee, the Indemnifying Party shall have the duty to either compromise or defend, at its own expense and by legal counsel (reasonably satisfactory to Indemnitee), such Claim. The Indemnifying Party shall promptly (and in any event not more than [***] after receipt of the Indemnitee’s original notice) notify the Indemnitee in writing that it acknowledges its obligation to indemnify the Indemnitee with respect to the Claim pursuant to this Article 15 and of its intention either to compromise or defend such Claim. Once the Indemnifying Party gives such notice to the Indemnitee, the Indemnifying Party is not liable to the Indemnitee for the fees of other legal counsel or any other expenses subsequently incurred by the Indemnitee in connection with such defense, other than the Indemnitee’s reasonable expenses of investigation and cooperation. However, the Indemnitee

shall have the right to employ separate legal counsel and to control the defense of a Claim at its own expense.

(c)    Cooperation. The Indemnitee shall cooperate fully with the Indemnifying Party and its legal representatives in the investigation and defense of any Claim. The Indemnifying Party shall keep the Indemnitee informed on a reasonable and timely basis as to the status of such Claim (to the extent the Indemnitee is not participating in the defense of such Claim) and conduct the defense of such Claim in a prudent manner.

(d)    Settlement. If an Indemnifying Party assumes the defense of a Claim, no compromise or settlement of such Claim may be effected by the Indemnifying Party without the Indemnitee’s written consent (which consent shall not be unreasonably withheld, conditioned or delayed), unless: (i) there is no finding or admission of any violation of law or any violation of the rights of any person and no effect on any other claims that may be made against the Indemnitee; (ii) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party; and (iii) the Indemnitee’s rights under this Agreement are not adversely affected. If the Indemnifying Party fails to assume defense of a Claim within a reasonable time, the Indemnitee may settle such Claim on such terms as it deems appropriate with the consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed), and the Indemnifying Party shall be obligated to indemnify the Indemnitee for such settlement as provided in this Article 15.

15.4    Limitation of Liability. EXCEPT FOR A PARTY’S OBLIGATIONS SET FORTH IN THIS ARTICLE 15, AND ANY BREACH OF ARTICLE 11 (CONFIDENTIALITY), IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY (OR THE OTHER PARTY’S AFFILIATES OR SUBLICENSEES) IN CONNECTION WITH THIS AGREEMENT FOR LOST REVENUE, LOST PROFITS, LOST SAVINGS, LOSS OF USE, DAMAGE TO GOODWILL, OR ANY CONSEQUENTIAL, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE OR INDIRECT DAMAGES UNDER ANY THEORY, INCLUDING CONTRACT, NEGLIGENCE, OR STRICT LIABILITY, EVEN IF THAT PARTY HAS BEEN PLACED ON NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.

16.2    Designation of Affiliates. Each Party may discharge any obligations and exercise any rights hereunder through delegation of its obligations or rights to any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such Party’s Affiliate.

16.3    Force Majeure. Both Parties shall be excused from the performance of their 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 takes reasonable efforts to remove the condition. Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a Force Majeure affecting such Party. If a Force Majeure persists for more than [***], then the Parties shall discuss in good faith the modification of the Parties’ obligations under this Agreement in order to mitigate the delays caused by such Force Majeure.

16.4    Assignment. Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other (which consent shall not be unreasonably withheld, conditioned or delayed), except that a Party may assign this Agreement (together with the other agreements between the Parties referenced in this Agreement, including

the Clinical Supply Agreement) without the other Party’s consent to any Affiliate or to a successor to all or substantially all of the business of such Party to which this Agreement relates, whether in a merger, sale of stock or units, sale of assets or other transaction. Any other assignment or transfer shall require the prior written consent of the other Party (which consent shall not be unreasonably withheld, conditioned or delayed). Any successor or assignee of rights and/or obligations permitted hereunder shall, in writing to the other Party, expressly assume performance of such rights and/or obligations. Any permitted assignment shall be binding on the successors of the assigning Party. [***] Any assignment or attempted assignment by either Party in violation of the terms of this Section 16.4 shall be null, void and of no legal effect.

16.5    Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision 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.

16.6    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.

16.7    Further Assurance. Each Party shall duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and cause to be done such further acts and things, including the filing of such assignments, agreements, documents, and instruments, as may be necessary or as the other Party may reasonably request in connection with this Agreement or to carry out more effectively the provisions and purposes hereof.

16.8    Relationship of the Parties. It is expressly agreed that Takeda, on the one hand, and Licensee, on the other hand, shall be independent contractors and that the relationship between the two Parties shall not constitute a partnership, joint venture or agency, including for Tax purposes. Neither Takeda nor Licensee 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 that Party and not of the other Party and all expenses and obligations incurred by reason of such employment shall be for the account and expense of such Party.

16.9    Counterparts. 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 and the same instrument. This Agreement may be executed by facsimile, .pdf or other electronically transmitted signatures and such signatures shall be deemed to bind each Party hereto as if they were the original signatures.

16.10    Construction.

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.

16.12    Entire Agreement. This Agreement, including the Exhibits hereto, sets forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties with respect to the subject matter hereof and supersedes, as of the Effective Date, all prior agreements and understandings between the Parties with respect to the subject matter hereof.
