8.11.2Non-Monetary Compensation. Upon any sale or other disposal of the Product that should be included within Net Revenues for any consideration other than an exclusively monetary consideration on bona fide arm’s length terms, then for purposes of calculating the Net Revenues under this Agreement, such Product shall be deemed to be [***].

8.11.3Multiple Product Offerings. In the event the Product is sold with one or more products or services for a single contracted price (together, a “Multiple Product Offering”) in a given country, Net Revenues in such country for such Multiple Product Offering shall be calculated by multiplying actual Net Revenues of such Multiple Product Offering in such country by the fraction A/(A+B) where A is the ASP of the Product, if sold separately, and B is the sum of the ASPs for each of the other products in the Multiple Product Offering, if sold separately. If, on a country-by-country basis, the other products in the Multiple Product Offering are not sold separately in said country, Net Revenues for the purpose of determining royalties of the Multiple Product Offering in such country shall be calculated by multiplying actual Net Revenues of such Multiple Product Offering in such country by the fraction A/D, where A is the ASP of the Product, if sold separately, and D is the ASP of the Multiple Product Offering. If neither the Product nor the other products are sold separately in a given country, the Parties shall determine Net Revenues for such Multiple Product Offering in such country by mutual agreement based on the relative contribution of the Product (excluding other products) and each other product in the Multiple Product Offering.

Section 8.12Clinical Supply Manufacturing Costs Calculation and True-Up.

After the Manufacturing Transfer, Manufacturing Standard Cost (in the case of Product manufactured in Amgen’s (or its designee’s) clinical manufacturing facility) or Manufacturing Actual Costs (in the case of Product manufactured in Amgen’s (or its designee’s) non clinical (i.e., commercial) manufacturing facility) for Product manufactured by Amgen and intended for use in a Clinical Study will be included as part of Amgen’s Global Development Costs at the time such Product is shipped to a site for use of such Product in a Clinical Study. In addition, due to the fact that Manufacturing Actual Costs may not be known at the time such costs are to be included within the Global Development Costs for a particular calendar quarter, Amgen will, to the extent any manufacturing costs are to be calculated using Manufacturing Actual Costs, use the then-current estimated Manufacturing Actual Costs for such calendar quarter. By March 31 of each calendar year, Amgen will reconcile any estimated Manufacturing Actual Costs included in Global Development Costs in the prior calendar year with the final Manufacturing Actual Costs for such Product and provide such reconciliation to KKUS. If such reconciliation evidences an over or under payment by either Party, a balancing payment will be made between the Parties in order to maintain the intended cost sharing allocation set forth in this Agreement within [***] days after delivery of such reconciliation report by Amgen and agreement thereon by the Parties, and subject further to [***].

During the Term, except as otherwise set forth in Section 10.2 (Allowed Activities), each Party shall not itself (and each Party shall ensure that its Affiliates do not), conduct or participate in, or advise, assist or enable any Third Party to conduct or participate in, any Distracting Program (the “Distracting Program Restriction”) in the Amgen Territory or in the KKC Territory.

Section10.2Allowed Activities. Notwithstanding anything in this Article X, each Party and its Affiliates will have the right to [***], subject to this Section 10.2 (Allowed Activities), and provided, for clarity, that no intellectual property or other rights of the other Party are granted hereunder to the Distracted Party with respect to a Distracting Product. At least [***] days prior to the anticipated initiation of the first [***] for such Distracting Product, the Party conducting such activities (the “Researching Party”) will notify the non-Researching Party and provide a non-confidential summary of the related Distracting Program to the non-Researching Party (“Program Notice”). If the non-Researching Party desires to evaluate such Distracting Program, then the non-Researching Party will notify the Researching Party within [***] days of its receipt of the Program Notice. Promptly after the Researching Party’s receipt of such evaluation notice, the Researching Party will provide the non-Researching Party with a confidential summary of the Distracting Program, including material pre-clinical data and

proposed development plan and budget (as well as such other information that the non-Researching Party may reasonably request), which summary will be deemed to be Confidential Information of the Researching Party under this Agreement (and the non-Researching Party shall be entitled to use such information solely for the purpose of evaluating whether to include such Distracting Program in the collaboration). Within [***] days of its receipt of such summary, the non-Researching Party will notify the Researching Party of its election to either (i) include the Distracting Program in the collaboration, in which case the (a) the Distracting Program will be included under the terms of this Agreement and all the technology, intellectual property and tangible materials (including biological compounds, chemical compounds, intermediates, assays, screens, animal models and reagents) of such Distracting Program will be considered within the Licensed KKC Patents, Licensed KKC Know-How, Licensed Amgen Patents, and Licensed Amgen Know-How, as applicable; (b) the Distracting Products included in the Distracting Program will be deemed Products hereunder; (c) the JDS will develop a Development Plan and Development Budget for each Distracting Product; and (d) the non-Researching Party will pay a one-time opt-in fee of [***], within [***] days following such election and, thereafter, all Global Development Costs and Commercialization and Related Costs with respect to each such Distracting Product will be shared [***] or (ii) decline to include such Distracting Program in the collaboration. If the non-Researching Party declines to include such Distracting Program in the collaboration, then (x) from and after the date of such election, the obligations of the Researching Party set forth in Section 10.1 (General) will no longer apply with respect to such Distracting Program, (y) the non-Researching Party shall destroy the confidential summary of the Distracting Program provided to it by the Researching Party (provided, that the non-Researching Party shall be entitled to retain one (1) copy of such information for its record-keeping purposes), and (z) for clarity, the Party’s rights and obligations with respect to the Product shall remain unchanged and each Party shall continue to perform its obligations hereunder.

Section10.3Distracting Transactions; Notice. Notwithstanding anything to the contrary herein, it shall not be deemed a breach of the Distracting Program Restriction by a Distracted Party if such Distracted Party enters into a Distracting Transaction and such Distracted Party complies with its obligations under this Section 10.3. If a Party enters into a Distracting Transaction (and thereby becomes a Distracted Party) then it will provide notice to the other Party (the “Affected Party”), within [***] Business Days after the first public announcement or disclosure of such Distracting Transaction and if no public announcement or disclosure occurs, within [***] Business Days after the closing of such transaction (the “Distracting Transaction Notice”), describing in reasonable detail, to the extent permitted by Applicable Law and without disclosing any proprietary information, the Distracting Program. During the pendency of any potential Distracting Transaction, and until the provisions of either Section 10.3.1 (Divestiture of a Distracting Program) or Section 10.3.2 (Termination of a Distracting Program) are fully implemented, the Distracted Party will Segregate the Distracting Program from programs for the Product. Any notice provided pursuant to this Section 10.3 shall include a notification as to whether the Distracted Party intends to Divest or terminate the Distracted Program.

10.3.1Divestiture of a Distracting Program. If the Distracted Party elects to Divest a Distracting Program arising from the Distracting Transaction, then it will Divest such Distracting

Program within [***]. If the Distracted Party fails to complete a Divestiture of the Distracting Program within [***], then the Distracted Party will be deemed to have chosen to terminate the Distracting Program, effective as of such [***] month anniversary, and will promptly comply with the requirements of Section 10.3.2 (Termination of a Distracting Program); provided that if at the expiration of such [***]month period, the Distracted Party has agreed terms with a Third Party to Divest the Distracting Program arising from the Distracting Transaction then such [***]month period will be extended as required for the Distracted Party and such Third Party to consummate the transaction, but in no event will such extension exceed an additional [***] days.

10.3.2Termination of a Distracting Program. If the Distracted Party elects to terminate a Distracting Program arising from a Distracting Transaction, it will terminate all activities of such Distracting Program within [***] [***] (other than any Clinical Studies or other activities which are being completed solely for ethical, regulatory, or legal obligations to complete the same and not for the purpose of obtaining Regulatory Approval). [***]

Section10.4Reasonable Restrictions. The Distracted Party acknowledges the provisions of this Article X are reasonable and necessary to protect the legitimate interests of the Affected Party and to encourage the free sharing of information between the Parties with respect to the Product, and the Distracted Party agrees not to contest such limitations in any proceeding. The Distracted Party acknowledges that the Affected Party would not have entered into this Agreement absent the restrictions set forth in this Article X and that a breach or threatened breach of this Article X would be likely to result in irreparable harm to the Affected Party for which there is no adequate remedy at law. Therefore, the Affected Party will be entitled to obtain from any court of competent jurisdiction injunctive relief, specific performance, and an equitable accounting of any earnings, profits or benefits arising out of any such breach. Nothing in this Section 10.4 (Reasonable Restrictions) is intended or will be construed to limit in any way either Party’s rights to equitable relief or any other remedy for breach of this or any other provision of this Agreement.

(a)In the event of an actual or reasonably suspected breach or violation of Security concerning the Personal Information (“Privacy Incident”), each Party shall notify the other of such incident without undue delay (but in no event later than [***] after discovery). In such event, each Party shall be responsible for fulfilling any reporting and notification obligations required under GDPR and other Applicable Law with regard to the data processing operations it carries out.

(b)The Parties hereby incorporate the EU Standard Contractual Clauses necessary to effectuate the compliant onward transfer of EU Personal Information outside of EU/EEA to third countries attached hereto as the Standard Contractual Clauses Schedule. In addition, the Parties agree to cooperate with each other to effectuate the compliant transfer of Personal Information applicable to other jurisdictions, which may include executing additional data transfer agreements.

(c)The Parties shall notify each other without delay (but in no event later [***] business days after receipt) in the event a data subject asserts one of his/her rights under GDPR

and other applicable data privacy and protection laws. With respect to patient data, any such notifications shall be made in a pseudonymous form using the subject’s trial-specific identification number only. If necessary and appropriate, the Parties shall reasonably cooperate with each other by providing the necessary information to ensure full and effective implementation of the rights of the data subject. Notification required under this Section shall be made as follows: [***]

(d)To the extent required under GDPR and Applicable Law, each receiving Party shall (i) make available to the other Party such information as is reasonably necessary to demonstrate the receiving Party's compliance with its obligations under GDPR and Applicable Law and this Agreement and (ii) allow for and contribute to audits and inspections conducted by the disclosing Party in accordance with the terms of this provision to demonstrate compliance with the receiving Party's obligations set out in this Agreement, GDPR and Applicable Law. Should a disclosing Party choose to exercise the right to conduct an audit or inspection as described in (ii) above, the disclosing Party shall designate an independent, qualified third-party that is reasonably acceptable to and approved by the receiving Party to perform such audit or inspection, at the disclosing Party’s cost and expense. The timing of such audit or inspection shall be agreed to by the Parties. The receiving Party shall document the results of such audits and inspections and present them to the disclosing Party for approval. If the receiving Party objects to the disclosing Party's request for audit or inspection, it shall advise the disclosing Party of its objections, the reasons for objecting, and reasonably work with the disclosing Party to tailor the audit to address such objections, to the extent commercially reasonable.

Without limiting the foregoing, where each Party is acting as “processor” (as defined under Applicable Law) of the other Party, such processor Party shall comply with the terms of the Privacy and Data Protection Schedule attached hereto.

Section13.5Information Security. The Parties agree to comply with the Information Security Schedule attached hereto (the “Information Security Schedule”) and the following:

THE FOREGOING SENTENCE WILL NOT LIMIT THE OBLIGATIONS OF EITHER PARTY TO INDEMNIFY THE OTHER PARTY FROM AND AGAINST SUCH DAMAGES AS ARE AWARDED TO A THIRD PARTY WITH RESPECT TO THIRD PARTY CLAIMS UNDER SECTION 14.1 (INDEMNITY BY KKC) OR SECTION 14.2 (INDEMNITY BY AMGEN).

Section13.8Disclosure Laws. Notwithstanding anything to the contrary in this Agreement, KKC acknowledges and agrees that (i) Amgen is permitted to publicly disclose information regarding this Agreement to comply with Applicable Laws (including without limitation the Physician Payment Sunshine Act and related requirements (collectively, “Disclosure Laws”)), and (ii) this information may include without limitation payments, or other transfers of value, made on behalf or at the request of Amgen to physicians, teaching hospitals, and other persons or entities that are the subject of the Disclosure Laws.

Article XIV.

INDEMNIFICATION AND INSURANCE

Section14.1Indemnity by KKC. KKC will defend, indemnify, and hold harmless Amgen, its Affiliates, and their respective directors, officers, employees, agents and representatives (collectively, “Amgen Indemnitees”), at KKC’s cost and expense, from and against any and all liabilities, losses, costs, damages, fees or expenses (including reasonable legal expenses and attorneys’ fees) (collectively, “Losses”) arising out of any Third Party Claims brought against any Amgen Indemnitee to the extent such Losses result from: (i) the negligence or willful misconduct of KKC or its Affiliates (or any employees, agents or representatives of any of them) in performing under this Agreement, (ii) a breach by KKC of Applicable Law or this Agreement, including the failure of KKC’s representations or warranties in Article XIII

(Representations, Warranties and Covenants) to be true in any material respect, (iii) the negligence or willful misconduct of KKC’s Sales Representatives or Medical Liaisons in connection with the activities under Section 6.4 (Co-Promotion Activities), (iv) prior to the Manufacturing Transfer, any product liability claims to the extent arising from the failure by KKC, its Affiliates or contractors in connection with the Manufacture of the Product, or (v) KKC’s or its Affiliates’ Development, Commercialization or Manufacture of the Product prior to or after the Effective Date. The indemnification obligations under this Section 14.1 exclude Losses to the extent they arise from (i), (ii) or (iii) below in Section 14.2 (Indemnity by Amgen) or are subject to a right of indemnification under the Supply Agreement.

Section14.2Indemnity by Amgen. Amgen will defend, indemnify, and hold harmless KKC, its Affiliates, and their respective directors, officers, employees, agents and representatives (collectively, “KKC Indemnitees”), at Amgen’s cost and expense, from and against any and all Losses arising out of any Third Party Claims brought against any KKC Indemnitee to the extent such Losses result from: (i) the negligence or willful misconduct of Amgen or its Affiliates (or any employees, agents or representatives of any of them) in performing under this Agreement, (ii) a breach by Amgen of Applicable Law or this Agreement, including the failure of Amgen’s representations or warranties in Article XIII (Representations, Warranties and Covenants) to be true in any material respect or (iii) Amgen’s or its Affiliates’ Development, Manufacture or Commercialization of, or conduct of Medical Affairs Activities with respect to, the Product. The indemnification obligations under this Section 14.2 exclude Losses to the extent they arise from (i) through (v)) above in Section 14.1 (Indemnity by KKC) or are subject to a right of indemnification under the Supply Agreement.

Section14.3Claim for Indemnification. Whenever any Third Party Claim or Loss arises for which a KKC Indemnitee or an Amgen Indemnitee (the “Indemnified Party”) may seek indemnification under this Article XIV, the Indemnified Party will promptly notify the other Party (the “Indemnifying Party”) of the Third Party Claim or Loss; provided that the failure by an Indemnified Party to give such notice will not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that the Indemnifying Party is actually prejudiced as a result of such failure. The Indemnifying Party will have exclusive control of the defense and settlement of all Third Party Claims for which it is responsible for indemnification and will assume defense thereof at its own expense promptly upon notice of such Third Party Claim. In no event will the Indemnifying Party settle such Third Party Claim without the prior written consent of the Indemnified Party, unless such settlement: (i) includes a complete release of the Indemnified Party from liability with respect to the Third Party Claim (including any cost sharing under this Agreement), and (ii) does not include any admission of wrongdoing by the Indemnified Party or a stipulation that any intellectual property or proprietary right of the Indemnified Party is invalid or unenforceable; provided that in the event consent is required by the Indemnifying Party for a settlement such consent shall not unreasonably withheld, conditioned or delayed. In the event of a disagreement regarding such settlement, such matter shall be escalated to the JSC. Notwithstanding the foregoing, the Indemnifying Party shall not be prohibited from entering into a settlement that involves one or more countries in addition to Amgen Territory so long as such settlement does not result in any liability or admission of wrongdoing by the Indemnified Party or a stipulation that any

intellectual property or proprietary right of the Indemnified Party is invalid or unenforceable. The Indemnified Party will have the right to employ separate counsel at the Indemnifying Party’s expense and to control its own defense of the applicable Third Party Claim if: (i) there are or may be legal defenses available to the Indemnified Party that are different from or additional to those available to the Indemnifying Party, or (ii) in the reasonable opinion of counsel to the Indemnified Party, a conflict or potential conflict exists between the Indemnified Party and Indemnifying Party that would make such separate representation advisable. For the avoidance of doubt, any Third Party Claims or Losses, to the extent indemnifiable pursuant to this Section 14.3, shall be excluded from the definition of “Commercialization and Related Costs.”

Section14.4Defense of Third Party Claims. Except as otherwise provided in Section 11.3 (Defense and Settlement of Third Party Claims) and Section 14.3 (Claim for Indemnification), each Party (such Party referred to as the “Defending Party”) will have the sole right, but not the obligation, to defend against any Third Party Claims made against it with respect to its activities hereunder. Each Party will notify the other Party (the “Assisting Party”) as promptly as practicable if any such Third Party Claim is commenced or threatened against it. The Assisting Party will reasonably assist the Defending Party and cooperate in any such litigation at Defending Party’s reasonable request. Without limiting the foregoing, the Defending Party will keep the Assisting Party advised of all material communications and actual and prospective filings or submissions regarding such action, and will provide the Assisting Party copies of and an opportunity to review and comment on any such communications, filings and submissions; provided that each Party will have the right to redact from any information disclosed to the other hereunder any information relating to a product other than the Product or relating to a device used in connection with, or the manufacture of, the Product. The Defending Party will control the defense and settlement of Third Party Claims, at the Defending Party’s expense. The Defending Party will not settle such Third Party Claim without the prior written consent of the other Party, unless such settlement: (i) includes a complete release of the Assisting Party from liability with respect to the Third Party Claim (including any cost sharing under this Agreement), and (ii) does not include any admission of wrongdoing by the Assisting Party; provided that in the event consent is required by the other Party for a settlement such consent shall not be unreasonably withheld, conditioned or delayed. In the event of a disagreement regarding such settlement, such matter shall be escalated to the JSC. In the event that a Third Party Claim is brought against both of the Parties (a “Joint Claim”), then the Parties will determine whether to defend against such Joint Claim, which of the Parties should be the Defending Party or whether the Parties should jointly control such defense and the strategy for such defense. This Section 14.4 will not apply to employment or similar personnel-related claims.

Section14.5Insurance. Each of the Parties will, at their own respective expense (and not subject to cost sharing hereunder) procure and maintain during the Term, insurance policies adequate to cover their obligations hereunder and consistent with the normal business practices of prudent pharmaceutical companies of similar size and scope (or reasonable self-insurance sufficient to provide materially the same level and type of protection). Such insurance will not create a limit to either Party’s liability hereunder.

MISCELLANEOUS

Section16.1Assignment; Change of Control. Neither this Agreement nor any rights or obligations hereunder may be assigned or otherwise transferred (whether by operation of

Applicable Law, general succession or otherwise) by either Party without the prior written consent of the other Party; provided that (i) either Party may assign this Agreement, and its rights and obligations hereunder, to an Affiliate only with the prior written consent of the other Party (not to be unreasonably withheld, conditioned or delayed), (ii) Amgen may (subject to Section 3.4 (Right of First Negotiation))) assign this Agreement and its rights and obligations hereunder in its entirety in connection with the transfer or sale of all or substantially all of the rights to the Product to which this Agreement relates, and (iii) either Party may assign this Agreement, and its rights and obligations hereunder in connection with a Change of Control. Notwithstanding anything to the contrary in this Agreement, KKC shall not be entitled to assign or otherwise transfer (whether by operation of Applicable Law, general succession or otherwise) its rights under Section 6.4 (Co-Promotion Activities) without the consent of Amgen and a Change of Control of KKC shall be deemed an assignment under this sentence. Any assignment not in accordance with this Agreement will be null and void ab initio. Subject to the foregoing, the rights and obligations of the Parties under this Agreement will be binding upon and inure to the benefit of the successors and permitted assigns of the Parties. Additionally, if this Agreement is assigned, in whole or in part, in accordance with its terms, then: (1) any Pharmacovigilance Agreement or Quality Agreement may be assigned, in whole or in part, by the assignor to the permitted assignee of this Agreement, and (2) the assignor’s ongoing and future obligations to the other Party under the Pharmacovigilance Agreement or Quality Agreement will be deemed terminated to the extent commensurate with the assignment of the corresponding obligations under this Agreement.

For purposes of the foregoing, “recruit”, “solicit” or “induce” shall not be deemed to mean: (a) circumstances where an employee of a Party initiates contact with the other Party or any of its Affiliates with regard to possible employment; or (b) general solicitations of employment not specifically targeted at employees of a Party or any of its Affiliates, including responses to general advertisements.

Section16.3Compliance with Laws. The Parties enter into this Agreement with the intent of conducting their relationship in full compliance with Applicable Law. Notwithstanding any unanticipated effect of any of the provisions herein, neither Party will intentionally conduct itself under the terms of this Agreement in a manner that does or would constitute a violation of Applicable Law. In the event that any Governmental Authority of competent jurisdiction determines that this Agreement or any material provision of this Agreement violates any Applicable Law, the Parties shall negotiate in good faith to amend this Agreement or the relevant provision thereof to remedy such violation in a manner that will not be inconsistent with the intent of the Parties or such provision.

100

within [***] days of delivery of the notice regarding such violation, then either Party may elect to terminate this Agreement upon written notice to the other.

Section16.4Change in Applicable Law. If any change in Applicable Law enacted after the Execution Date could reasonably be expected to have a material adverse effect on the ability of either Party to carry out its obligations, or receive the benefits under, this Agreement, such Party, upon written notice to the other Party (which notice may be given within [***] following enactment of such change in Applicable Law, whether or not such change is effective on the date of such enactment or is effective at a later date), may request renegotiation of this Agreement.

16.5.3Any Dispute shall first be referred to the Alliance Managers for each of the Parties to facilitate and assist resolution of such Dispute, including scheduling an initial meeting between their respective Designated Officers for attempted resolution within [***] Business Days after such referral if such matter had not previously been reviewed by the Designated Officers under Section 2.2.5(b) (JSC Deadlocks). If such Dispute is not resolved within [***] days after such referral to the Alliance Managers and, if applicable, the meeting between the Designated Officers, then either Amgen or KKC may commence arbitration under Section 16.5 (Governing Law; Dispute Resolution).

Section16.6Construction. The definitions of the terms herein will apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun will include the corresponding masculine, feminine and neuter forms. The words “include”, “includes” and “including” will be deemed to be followed by the phrase “without limitation”. The word “or” is used in the inclusive sense (and/or).

Section16.8Entire Agreement. This Agreement, including the attached Exhibits and Schedules, constitutes the entire agreement between the Parties as to the subject matter of this Agreement, and supersedes and merges all prior or contemporaneous negotiations, representations, agreements and understandings regarding the same.

Section16.9Force Majeure. Neither Party will be liable for delay or failure in the performance of any of its obligations hereunder (other than the payment of money) to the extent such delay or failure is due to causes beyond its reasonable control, including acts of God, fires, floods, earthquakes, labor strikes, hostilities, acts of war, terrorism, civil unrest, national emergencies, pandemics or epidemics (each, a “Force Majeure”); provided that the affected Party promptly notifies the other Party in writing (and continues to provide monthly status updates to the other Party for the duration of the effect); and provided further that the affected Party uses its commercially reasonable efforts to avoid or remove such causes of non-performance and to mitigate the effect of such occurrence, and will continue performance with reasonable dispatch whenever such causes are removed.

Section16.10Further Assurances. Each Party agrees to do and perform all such further acts and things and will execute and deliver such other agreements, certificates, instruments and documents necessary or that the other Party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and to evidence, perfect or otherwise confirm its rights hereunder.

Section16.12No Set-Off. Except as expressly set forth in Section 9.6.1 (Withholding) or Section 9.6.2 (Indirect Taxes), neither Party will have the right to deduct from amounts otherwise payable hereunder any amounts payable to such Party (or its Affiliates) from the other Party (or its Affiliates), whether pursuant to this Agreement or otherwise.

Any such notice will be deemed given on the date delivered. A Party may add, delete (so long as at least one person is remaining), or change the person or address to which notices should be sent at any time upon written notice delivered to the other Party in accordance with this Section 16.12.

Section16.14Relationship of the Parties. Each Party is an independent contractor under this Agreement. Nothing contained herein will be deemed, for the purpose of any Applicable Law, to create an employment, agency, joint venture or partnership relationship between the Parties or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. The Parties will operate their own businesses separately and independently and they will hold themselves out as, act as, and constitute independent contractors in all respects and not as principal and agent, partners or joint venturers. Neither Party will have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever. Neither Party shall make any filing or initiate any communication with a Governmental Authority that is inconsistent with this Section 16.14 and each Party shall notify the other Party within [***] days of receiving any written communication from a Governmental Authority that asserts a position that is inconsistent with this Section 16.14.

Section16.15Severability. To the fullest extent permitted by Applicable Law, the Parties waive any provision of Applicable Law that would render any provision in this Agreement invalid, illegal or unenforceable in any respect. If any provision of this Agreement is held to be invalid, illegal or unenforceable, in any respect or to any extent, then in such respect and to such extent such provision will be given no effect by the Parties and will not form part of this Agreement. To the fullest extent permitted by Applicable Law, all other provisions of this Agreement will remain in full force and effect and the Parties will use their commercially reasonable efforts to negotiate a provision in replacement of the provision held invalid, illegal or unenforceable that is consistent with Applicable Law and achieves, as nearly as possible, the original intention of the Parties.

104

Section16.16Third Party Beneficiaries. Except as expressly provided with respect to Amgen Indemnitees or KKC Indemnities in Article XIV (Indemnification and Insurance), there are no Third Party beneficiaries intended hereunder and no Third Party will have any right or obligation hereunder.

Section16.17Waivers and Modifications. The failure of any Party to insist on the performance of any obligation hereunder will not be deemed to be a waiver of such obligation. Waiver of any breach of any provision hereof will not be deemed to be a waiver of any other breach of such provision or any other provision on such occasion or any other occasion. No waiver, modification, release or amendment of any right or obligation under or provision of this Agreement will be valid or effective unless in writing and signed by all Parties hereto.
