In the event Moderna (or, at Moderna’s direction, its applicable Affiliate, subcontractor or Sublicensee) obtains any license described in this Section 7.5.4(c) (Third Party Intellectual Property) subject to Section 7.5.4(d) (Maximum Reduction), [***] of the payments that Moderna actually pays to such Third Party(ies) that are attributable to the Development, Manufacture, or Commercialization of such Licensed Product in a country during a Calendar Quarter may be credited against amounts otherwise payable by Moderna to CytomX under this Article 7 (Fees, Royalties, & Payments) for such Licensed Product in such country in such Calendar Quarter. Notwithstanding anything

22

to the contrary, CytomX shall be solely responsible for any license fees, milestones, royalties, or other payments owed to Third Parties under or in connection with any agreement entered into between CytomX and a Third Party on or prior to the Effective Date under which Moderna is granted a sublicense under this Agreement (whether or not any such agreement is disclosed to Moderna prior to the Effective Date).

(d)Maximum Reduction. The maximum aggregate reduction with respect to any Licensed Product in any country during any Calendar Quarter pursuant to this Section 7.5.4 (Royalty Reductions) (alone or in combination) shall be capped at [***] of the amount of the royalty that would be payable in respect of Net Sales in such country under Section 7.5.3 (Royalty Rates), prior to any such reductions; [***].

Section 7.9Reports; Records and Audits.

7.9.1 Reports. After the First Commercial Sale of the first Licensed Product by Moderna and until expiration or termination of this Agreement, Moderna shall prepare and (within [***] after the end of each Calendar Quarter) deliver to CytomX reports of the sale of Licensed Products by Moderna or its Affiliates, and their respective Sublicensees [***] together with the corresponding royalty payment or other consideration to be paid to CytomX, specifying [***].

7.9.2 Moderna Records. Moderna will keep complete and accurate records of royalty, milestone and other payments required under this Agreement, for a period of [***] after the end of the Calendar Year in which such were incurred or such payment was due. Moderna shall require its Affiliates, and its and their respective Sublicensees to retain and provide to Moderna all records of payments that Moderna would be required to keep as if sales of Licensed Product by such Affiliates or Sublicensees were sales of Licensed Product by Moderna, to enable CytomX to audit such records pursuant to this Section 7.9 (Reports; Records and Audits).

7.9.3 CytomX Records. CytomX will keep complete and accurate records of its Preclinical Research Costs with respect to each Licensed Product for a period of [***] after the end of the Calendar Year in which such Preclinical Research Costs were incurred. Without limiting the foregoing, CytomX shall calculate and maintain records of FTE hours incurred by it in the same manner as used for other products developed by CytomX.

7.9.4 Audits. Each of CytomX and Moderna (the “Auditing Party”) will have the right, not more than [***] at its own expense, to have a nationally recognized, independent, certified public accounting firm, selected by it and subject to the other Party’s prior written consent (which shall not be unreasonably withheld, conditioned or delayed), review any such records of the other Party and its Affiliates (the “Non-Auditing Party”) in the location(s) where such records are maintained upon reasonable written notice (which shall be no less than [***] prior written notice) and during regular business hours and under obligations of strict confidence, for the sole purpose of verifying the basis and accuracy of payments made under this Agreement within the [***] period preceding the date of the request for review. Upon either Party’s written request, the other Party shall use good faith efforts to conduct audits of its subcontractors and Sublicensees (at the requesting Party’s cost), and the requesting Party shall have the right to receive and retain a copy of the applicable audit report. No Calendar Year will be subject to audit under this Section 7.9.4 (Audits) more than [***] without the consent of the Non-Auditing Party. The Non-Auditing Party will receive a copy of each such report within [***] following receipt by the Auditing Party, and such accounting firm shall report to the Parties only whether or not such calculations are correct and the amount of any discrepancy. No other information shall be shared. The Auditing Party shall treat the results of any such review of the Non-Auditing Party’s records under this Section 7.9.4 (Audits) as Confidential Information of the Non-Auditing Party and subject to the terms of Article 12 (Confidentiality). Should such inspection lead to the discovery of a discrepancy to the Auditing Party’s detriment, the Non-Auditing Party will, within [***] after receipt of such report from the accounting firm, pay any undisputed amount of the discrepancy together with interest at the rate set forth in Section 7.10 (Late Payments). The Auditing Party will pay the full cost of the review unless the underpayment of amounts due to the Auditing Party with respect to audited royalty or sales milestone, is more than [***], of the amount due for the entire period being examined, in which case, the Non-Auditing Party will pay the cost charged by such accounting firm for such review; provided that reimbursement for accounting firm fees shall (a) be no more than would have been paid by the Auditing Party had such reimbursement

24

not been required and (b) not include any contingency fee charged by the auditor (or any other increased fee resulting from the auditor discovering discrepancies). Should the audit lead to the discovery of a discrepancy to the Non-Auditing Party’s detriment, the Non-Auditing Party may credit the amount of the discrepancy, [***], against future payments payable to the Auditing Party under this Agreement or, if there are no such payments payable, then the Auditing Party shall pay to the Non-Auditing Party the amount of the discrepancy, [***], within [***] of the Auditing Party’s receipt of the report.

Section 7.10Late Payments. In the event that any undisputed payment due hereunder is not made when due, the payment shall accrue interest beginning on [***] thereof, calculated at [***]; provided, however, that in no event shall such annual interest rate exceed the maximum rate permitted by Law. Each such payment when made shall be accompanied by all interest so accrued. Said interest and the payment and acceptance thereof shall not negate or waive the right of any Party to seek any other remedy, legal or equitable, to which it may be entitled because of the delinquency of any payment, including termination of this Agreement as set forth in Article 12 (Termination). With respect to any disputed payments, no interest payment shall be due until such dispute is resolved and the interest which shall be payable thereon shall be based on the finally-resolved amount of such payment, calculated from the original date on which the disputed payment was due through the date on which payment is actually made.

Section 7.11Taxes.

7.11.1 Withholding. Subject to Section 7.11.3 (German Exemption Certificate), in the event that any Law requires a Party making any payment pursuant to this Agreement (the “Paying Party”) to withhold taxes with respect to any such payment, the Paying Party (a) will notify the non-Paying Party of such withholding requirement prior to making the payment to the non-Paying Party (such notice, which shall include the authority, basis and method of calculation for the proposed deduction or withholding, shall be given at least a reasonable period of time before such deduction or withholding is required, in order for the non-Paying Party to obtain reduction of or relief from such deduction or withholding), and (b) provide such assistance to the non-Paying Party, including the provision of such standard documentation as may be required by a tax authority, as may be reasonably necessary in the non-Paying Party’s efforts to claim an exemption from or reduction of such taxes. The Paying Party will, in accordance with such Law, withhold taxes from such payment, remit such taxes to the appropriate tax authority, and furnish the non-Paying Party with proof of payment of such taxes within [***] following the payment. If taxes are so withheld and paid to a tax authority, the Paying Party shall provide reasonable assistance to the non-Paying Party to obtain a refund of taxes withheld, or obtain a credit with respect to taxes paid. The non-Paying Party shall provide the Paying Party any tax forms (including Internal Revenue Service Forms W-9 or applicable W-8) that may be reasonably necessary in order for the Paying Party to determine whether to withhold tax on any such payments or to withhold tax on such payments at a reduced rate under applicable Law, including any applicable bilateral income tax treaty. [***].

7.11.2 Indirect Taxes. All payments due to the non-Paying Party from the Paying Party pursuant to this Agreement shall be paid exclusive of any value-added tax, sales tax, consumption taxes and other similar taxes (“Indirect Taxes”) (which, if applicable, shall be payable by the Paying Party upon receipt of a valid Indirect Tax invoice). If the non-Paying Party determines that it is required to report any such tax, the Paying Party shall promptly provide the non-Paying Party with applicable receipts and other documentation necessary or appropriate for such report. For clarity, this Section 7.11.2 (Indirect Taxes) is not intended to limit the Paying Party’s right to deduct value-added taxes in determining Net Sales.

25

7.11.3 German Exemption Certificate. Notwithstanding Section 7.11.1 (Withholding) and 7.11.2 (Indirect Taxes), if at any time the CytomX IP includes intellectual property that is registered in a German public book or register, CytomX shall obtain and provide Moderna with a valid certificate issued by the applicable German authorities establishing CytomX’s exemption from German withholding tax (a “German Exemption Certificate”), provided, however, that a German Exemption Certificate shall not be required if current German law changes and/or if obtaining and providing a German Exemption Certificate is no longer required, in each case, to exempt such payment from German withholding tax. Intellectual property shall be considered registered as soon as an application is filed (even if it is not yet granted) and intellectual property shall be considered registered in Germany if it has been filed with or validated (e.g., under the Patent Cooperation Treaty) in Germany or in a German E.U. office or non-German E.U. office (in the case of Patent Rights, the German Patent and Trademark Office (Deutsches Patent- and Markenamt) or European Patent and Trademark Office under the European Patent Convention), if filing or validating such intellectual property in such German EU office or non-German EU office would be considered filing or validating such intellectual property in Germany under German law. Notwithstanding Section 7.11.1 (Withholding) and 7.11.2 (Indirect Taxes), if any payments are due to CytomX hereunder with respect to such CytomX IP and, at the time such payment is to be made, Moderna is not in possession of a valid and effective German Exemption Certificate, Moderna shall inform CytomX and CytomX may elect to either have (i) Moderna delay making such payment until such time as CytomX receives such a German Exemption Certificate or (ii) Moderna withhold such amounts from such payment as determined by Moderna, in which case no tax gross up amount shall be payable to CytomX. If Moderna withholds any amount under (ii) above, Moderna shall remit such withheld amount to the applicable German tax authorities and provide CytomX with reasonable evidence of such payment in a form and with such details as reasonably requested by CytomX. Notwithstanding anything to the contrary in this Agreement, Moderna shall not withhold taxes on the Upfront Payment due and payable to CytomX under Section 7.1 (Upfront Payment). As applicable, CytomX will file for the German Exemption Certificate within [***] of the Effective Date and provide reasonable evidence of such filing to Moderna. Moderna authorizes CytomX to share this Agreement with the applicable German Tax authorities and CytomX tax counsel for the sole purpose of applying for the German Exemption Certificate, notwithstanding anything to the contrary in Article 12 (Confidentiality). In the event it is determined that CytomX is not eligible for the German Exemption Certificate and is definitively denied by the German Tax Authorities or CytomX fails to apply for the German Exemption Certificate within [***] of the Effective Date, CytomX shall work in good faith to compensate Moderna for the applicable withholding related to the payment in Section 7.1 (Upfront Payment) and taxes in this Section 7.11.3 (German Exemption Certificate).

Section 7.12No Other Compensation. Each Party hereby agrees that the terms of this Agreement fully define all consideration, compensation and benefits, monetary or otherwise, to be paid, granted or delivered by one 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.

Section 7.13No Limitation. Nothing contained in this Article 7 (Fees, Royalties and Payments) shall in any way limit either Party’s right to indemnification under this Agreement or to otherwise recover damages for breach of this Agreement.

Article 10. INDEMNIFICATION

Section 10.1Indemnity.

10.1.1 By CytomX. CytomX agrees to defend Moderna, its Affiliates, and each of their respective directors, officers, employees and agents (the “Moderna Indemnified Parties”), at CytomX’s cost and expense, and will indemnify and hold Moderna and the other Moderna Indemnified Parties harmless from and against any claims, losses, costs, damages, fees or expenses (including reasonable legal fees and expenses) (collectively, “Losses”) in connection with any claims, actions, demands, suits or proceedings [***]; except, in each case, to the extent such Losses result from clause (a), (b) or (c) of Section 10.1.2 (Indemnity—By Moderna).

10.1.2 By Moderna. Moderna agrees to defend CytomX, its Affiliates and their respective directors, officers, employees and agents (the “CytomX Indemnified Parties”), at Moderna’s cost and expense, and will indemnify and hold CytomX and the other CytomX Indemnified Parties harmless from and against any Losses in connection with any Third Party Claims to the extent arising out of or resulting from [***]; except, in each case, to the extent such Losses result from clause (a), (b) or (c) of Section 10.1.1 (Indemnity—By CytomX).

37

Section 10.2Procedure.

10.2.1 Notice. The indemnified Party (“Indemnitee”) will promptly notify the indemnifying Party (“Indemnitor”) in writing of the assertion or the commencement of the relevant Third Party Claim; provided, however, that any failure or delay to notify shall not excuse any obligation of the Indemnitor, except to the extent the Indemnitor is actually prejudiced thereby. Such notice must contain a description of the claim and the nature and amount of any Losses (to the extent that the nature and the amount of such Losses is known at such time). The Indemnitee shall furnish promptly to the Indemnitor copies of all papers and official documents received in respect of any Losses and Third Party Claims.

10.2.2 Control of Defense. The Indemnitee hereby grants the Indemnitor the right to assert sole management and control, at the Indemnitor’s sole expense, of the defense of such Third Party Claim and its settlement; provided, however, that the Indemnitor shall not settle any such Third Party Claim without the prior written consent of the Indemnitee if such settlement does not include a complete release from liability or if such settlement would involve the Indemnitee undertaking an obligation (including the payment of money by the Indemnitee), would bind or impair the Indemnitee, or includes any admission of wrongdoing by the Indemnitee or that any intellectual property or proprietary right of Indemnitee or this Agreement is invalid, narrowed in scope or unenforceable. The assertion of the defense of a Third Party Claim by the Indemnitor shall not be construed as an acknowledgment that the Indemnitor is liable to indemnify the Indemnitee in respect of the Third Party Claim, nor shall it constitute a waiver by the Indemnitor of any defenses it may assert against the Indemnitee’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the Indemnitor may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the Indemnitor, which shall be reasonably acceptable to the Indemnitee. In the event the Indemnitor assumes the defense of a Third Party Claim, except as provided in this Section 10.2.2 (Control of Defense), the Indemnitor shall not be liable to the Indemnitee for any legal expenses subsequently incurred by such Indemnitee in connection with the analysis, defense or settlement of the Third Party Claim unless specifically requested in writing by the Indemnitor. In the event that it is ultimately determined that the Indemnitor is not obligated to indemnify, defend or hold harmless the Indemnitee from and against the Third Party Claim, the Indemnitee shall reimburse the Indemnitor for any Losses incurred by the Indemnitor in defense of the Third Party Claim. The Indemnitee shall have the right (at its own expense) to be present in person or through counsel at all legal proceedings giving rise to the right of indemnification. Notwithstanding the foregoing, the Indemnitee will have the right to employ separate counsel at the Indemnitor’s expense and to control its own defense of the applicable Third Party Claim if: (a) the employment thereof, and the assumption by the Indemnitor of such expense, has been specifically authorized by the Indemnitor in writing, (b) the Indemnitor has failed to assume the defense and employ counsel in accordance with this Section 10.2.2 (Control of Defense) (in which case, the Indemnitee shall control the defense), (c) there are or may be legal defenses available to the Indemnitee that are different from or additional to those available to the Indemnitor, or (d) in the reasonable opinion of counsel to the Indemnitee, a conflict or potential conflict exists between the Indemnitee and the Indemnitor that would make such separate representation advisable; provided that in no event will the Indemnitor be required to pay fees and expenses under this sentence for more than one firm of attorneys in any jurisdiction in any one legal action or group of related legal actions. In such event, the Indemnitee shall not settle or compromise such Third Party claim without the prior written consent of the Indemnitor, such consent not to be unreasonably withheld, conditioned or delayed. The Indemnitor shall not be liable for any settlement, compromise or other voluntary disposition of a Loss by an Indemnitee that is reached without the written consent of the Indemnitor.

38

10.2.3 Cooperation. Regardless of whether the Indemnitor chooses to defend or prosecute any Third Party Claim, Indemnitee shall, and shall cause each other indemnitee to, cooperate in the defense or prosecution thereof and shall furnish such records, 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 Indemnitor to, and reasonable retention by the Indemnitee of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnitees and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the Indemnitor shall reimburse the Indemnitee for all of its reasonable out-of-pocket expenses in connection therewith as set forth in Section 10.2.4 (Expenses).

10.2.4 Expenses. The reasonable and verifiable costs and expenses, including costs, expenses, fees and disbursements of counsel, incurred by the Indemnitee pursuant to Section 10.2.3 (Cooperation) shall be reimbursed on a monthly basis in arrears by the Indemnitor, without prejudice to the Indemnitor’s right to contest the Indemnitee’s right to indemnification and subject to refund in the event the Indemnitor is ultimately held not to be obligated to indemnify the Indemnitee.

Article 11.limitations of liability

Section 12.4Relationship to the Confidentiality Agreement. This Agreement supersedes the Confidential Disclosure Agreement; provided, however, that all “Confidential Information” disclosed or received by the Parties thereunder will be deemed “Confidential Information” hereunder and will be subject to the terms and conditions of this Agreement.

Section 12.5Attorney-Client Privilege. Neither Party is waiving, nor will be deemed to have waived or diminished, any of its attorney work product protections, attorney-client privileges or similar protections and privileges recognized under the applicable Law of any jurisdiction as a result of disclosing information pursuant to this Agreement, or any of its Confidential Information (including Confidential Information related to pending or threatened litigation) to the Receiving Party, regardless of whether the Disclosing Party has asserted, or is or may be entitled to assert, such privileges and protections. The Parties may become joint defendants in proceedings to which the information covered by such protections and privileges relates and may determine that they share a common legal interest in disclosure between them that is subject to such privileges and protections, and in such event, may enter into a joint defense agreement setting forth, among other things, the foregoing principles but are not obligated to do so.

Section 12.6Survival. All Confidential Information shall continue to be subject to the terms of this Agreement for the period set forth in Section 12.1.2 (Restrictions).

Article 13. TERM & TERMINATION

Section 13.1Term. The term of this Agreement shall commence on the Effective Date, and unless terminated earlier as provided in this Article 13 (Term and Termination), shall continue in full force and effect, on a Licensed Product-by-Licensed Product and country-by-country basis, until expiration of the obligation to make payments under this Agreement with respect to each Licensed Product in each country (the “Term”).

Section 13.2Termination by CytomX.

13.2.1 Moderna Breach. CytomX will have the right to terminate this Agreement in the event of any material breach by Moderna of any terms and conditions of this Agreement; provided, however, that such termination will not be effective if such breach has been cured within [***] after written notice thereof is given by CytomX to Moderna specifying the nature of the alleged breach; provided further, however, if such breach (except for payment breaches) is not reasonably subject to cure within [***] after receipt of written notice thereof, then Moderna shall continue to use good faith efforts to cure such breach and shall have provided to CytomX a written plan intended to cure (and that Moderna reasonably believes will cure) such breach as soon as reasonably practicable thereafter. Notwithstanding the foregoing in this Section 13.2.1 (Moderna Breach), in the event of a good faith dispute as to whether a material breach by Moderna allowing for termination hereunder has occurred, the foregoing cure period with respect thereto will be tolled pending final resolution of such dispute in accordance with the terms of this Agreement; provided, however, if such dispute relates to payment, such tolling of the cure period will only apply with respect to payment of the disputed amounts, and not with respect to any undisputed amount.

13.3.3 Other Termination for Cause.

44

initiates or asserts any Moderna Patent Challenge and fails to initiate rescission of such Moderna Patent Challenge within [***] after such written notice and thereafter fails to rescind such Moderna Patent Challenge within [***] after such written notice. In the event any Sublicensee (or any Person acting on its behalf) of CytomX initiates or asserts any Moderna Patent Challenge in any forum, CytomX shall, upon written request by Moderna, immediately terminate the applicable sublicense agreement with such Sublicensee.

If Moderna is conducting (or having conducted on its behalf) any on-going clinical studies for which it has responsibility hereunder in which patient dosing has commenced, Moderna shall either (a) continue to conduct such clinical studies, or (b) responsibly wind-down, in accordance with accepted biopharmaceutical industry norms and ethical practices, and in the case of (a) and (b) Moderna will be responsible for any costs associated therewith.

13.4.2 Termination of Licenses and Sublicense; Payments. Except as set forth herein, all relevant licenses and sublicenses granted under Article 4 (License Grant), as of the effective date of such termination, shall terminate automatically unless otherwise agreed by the Parties. All undisputed amounts due or payable to a Party hereunder that were accrued prior to the date of termination shall remain due and payable except as otherwise set forth in the last sentence of this Section 13.4.2 (Termination of Licenses and Sublicense; Payments). Upon the effective date of such termination Moderna will have no further diligence obligations under this Agreement.

13.4.3 Destruction of Confidential Information. Each Party shall destroy or cause to be destroyed (or, at the other Party’s written request, return or cause to be returned) all Confidential

45

Information of the other Party in the possession of such Party or its Affiliates or Sublicensees as of the effective date of expiration or termination (with the exception of one copy of such Confidential Information, which may be retained by the legal department of the Party that received such Confidential Information to confirm compliance with the non‑use and non‑disclosure provisions of this Agreement), and any Confidential Information of the other Party contained in its laboratory notebooks or databases; provided that each Party may retain and continue to use such Confidential Information of the other Party to the extent necessary to exercise any surviving rights, licenses or obligations under this Agreement.

Section 13.5Product-Specific Collaboration IP. After any termination of this Agreement, [***].

Section 13.6Remedies. Except as otherwise expressly provided herein, any termination in accordance with the provisions hereof shall not limit remedies that may otherwise be available in law or equity.

Article 14. MISCELLANEOUS

Section 14.1Entire Agreement; Amendment. This Agreement and all Exhibits attached hereto or thereto, constitute the entire agreement between the Parties as to the subject matter hereof (and all references to this Agreement shall be deemed to include the Exhibits hereto). All prior and contemporaneous negotiations, representations, warranties, agreements, statements, promises and understandings with respect to the subject matter of this Agreement, including the Confidential Disclosure Agreement, are hereby superseded and merged into, extinguished by and completely expressed by this Agreement. Neither of the Parties shall be bound by or charged with any written or oral agreements, representations, warranties, statements, promises or understandings not specifically set forth in this Agreement. No amendment, supplement or other modification to any provision of this Agreement shall be binding unless in writing and signed by Moderna and CytomX.

Section 14.2Section 365(n) of the Bankruptcy Code. All rights and licenses granted under or pursuant to any section of this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101(35A) of the U.S. Bankruptcy Code to the extent permitted thereunder. The Parties shall retain and may fully exercise all of their respective rights and elections under the U.S. Bankruptcy Code. Upon the bankruptcy of any Party, the non-bankrupt Party shall further be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property, and such, if not already in its possession, shall be promptly delivered to the non-bankrupt Party, unless the bankrupt Party elects to continue, and continues, to perform all of its obligations under this Agreement. All rights granted to either Party under this Agreement shall be deemed to exist immediately before the occurrence of any bankruptcy case in which the other Party is the debtor.

Section 14.3Independent Contractors. The relationship between Moderna and CytomX created by this Agreement is solely that of independent contractors. This Agreement does not create any agency, distributorship, employee-employer, partnership, joint venture or similar business relationship between the Parties, including for all tax purposes. No such Party is a legal representative of the other Party, and no such Party can assume or create any obligation, representation, warranty or guarantee, express or implied, on behalf of the other Party for any purpose whatsoever. Each such Party shall use its own discretion and shall have complete and authoritative control over its employees and the details of performing its obligations under this Agreement.

Section 14.4Governing Law; Jurisdiction. This Agreement and its effect are subject to and shall be construed and enforced in accordance with the law of the State of New York, without regard to its conflicts of laws, except as to any issue which depends upon the validity, scope or enforceability of any Patent Right, which issue shall be determined in accordance with the laws of the country in which such patent was issued. Except to the extent otherwise set forth in Section 14.5 (Dispute Resolution), each of the Parties hereby irrevocably and unconditionally (a) consents to submit to the exclusive jurisdiction of the courts of the State of New York located in the City of New York for any matter arising out of or relating to this Agreement and the transactions contemplated hereby, and agrees not to commence any litigation relating thereto except in such courts, (b) waives any objection to the laying of venue of any matter arising out of this Agreement or the transactions contemplated hereby in the courts of the State of New York located in the City of New York, and (c) waives and agrees not to plead or claim in any such court that any such matter brought in any such court has been brought in an inconvenient forum. The Parties agree that a final judgment in any such matter shall be conclusive and may be enforced in other

47

jurisdictions by suits on the judgment or in any other manner provided by law. Any proceeding brought by either Party under this Agreement shall be exclusively conducted in the English language.

Section 14.5Dispute Resolution.

14.5.1 Disputes; Resolution by Executive Officers. The Parties recognize that disputes as to certain matters may from time to time arise during the Term that relate to decisions to be made by the Parties herein or to the Parties’ respective rights and/or obligations hereunder. It is the desire of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to arbitration or litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Section 14.5 (Dispute Resolution) if and when a dispute arises under this Agreement, subject to Section 2.2.5 (Decisions) and Section 14.5.3 (Injunctive Relief). Accordingly, any disputes, controversies or claims that may arise between the Parties out of or in relation to or in connection with this Agreement shall be promptly presented to the Alliance Managers for resolution. If the Alliance Managers are unable to resolve such dispute within [***] after a matter has been presented to them, then upon the request of either Party by written notice, the Parties agree to meet and discuss in good faith a possible resolution thereof, which good faith efforts shall include at least one in-person meeting between the Executive Officers of each Party within [***] after receipt by the other Party of such written notice. If any such matter, other than a matter within the final decision-making authority of Moderna, is not resolved within [***] following presentation to the Executive Officers, then either Party may invoke the provisions of Section 14.5.2 (Arbitration).

14.5.2 Arbitration. Any dispute that is not resolved pursuant to Section 14.5.1 (Disputes; Resolution by Executive Officers), shall be settled by binding arbitration to be conducted as set forth in this Section 14.5.2 (Arbitration).

(a)Either Party, following the end of the [***] period referenced in Section 14.5.1 (Disputes; Resolution by Executive Officers), may refer such issue to arbitration by submitting a written notice of such request to the other Party. In any proceeding under this Section 14.5.2 (Arbitration), there shall be one (1) arbitrator chosen upon mutual agreement of the Parties. If the Parties do not agree upon a single arbitrator within [***] after delivery of such notice, each Party will nominate one arbitrator in accordance with the then current rules of the Judicial Arbitration and Mediation Services (“JAMS”). The two (2) arbitrators so nominated will nominate a third arbitrator to serve as the single arbitrator of the dispute, such nomination to be made within [***] after the selection of the second arbitrator. The arbitrator shall be neutral and independent of both Parties and all of their respective Affiliates, shall have significant experience and expertise in licensing and partnering agreements in the pharmaceutical and biotechnology industries, shall have appropriate experience with respect to the matter(s) to be arbitrated, and shall have some experience in mediating or arbitrating issues relating to such agreements. In the case of any dispute involving Section 6.2 (Diligence), including an alleged failure to use Commercially Reasonable Efforts, the arbitrator shall in addition be an individual with experience and expertise in the worldwide development and commercialization of pharmaceuticals and the business, legal and scientific considerations related thereto. In the case of a dispute involving a scientific or accounting matter or determination, an expert having applicable expertise and experience will be selected by the Parties to assist the arbitrator in such scientific or accounting matter or determination (and the arbitrator will select such expert if the Parties cannot agree on such expert within [***] following the selection of the arbitrator). The governing law in Section 14.4 (Governing Law; Jurisdiction) shall govern such proceedings. No individual will be appointed to arbitrate a dispute pursuant to this Agreement unless he or she agrees in

48

writing to be bound by the provisions of this Section 14.5.2 (Arbitration). The place of arbitration will be New York, New York, United States unless otherwise agreed to by the Parties, and the arbitration shall be conducted in English.

(b)The arbitrator shall set a date for a hearing that shall be held no later than [***] following his or her appointment as the arbitrator. The Parties shall have the right to be represented by counsel. Except as provided herein, the arbitration shall be governed by the Comprehensive Arbitration Rules of JAMS applicable at the time of the notice of arbitration pursuant to Section 14.5.2(a) (Arbitration), including the right of each Party to undertake document requests and up to [***] depositions.

(c)The arbitrator shall use his or her best efforts to rule on each disputed issue within [***] after completion of the hearing described in Section 14.5.2(b) (Arbitration). The determination of the arbitrator as to the resolution of any dispute shall be binding and conclusive upon the Parties. All rulings of the arbitrator shall be in writing and shall be delivered to the Parties as soon as is reasonably possible. Nothing contained herein shall be construed to permit the arbitrator to award punitive, exemplary or any similar damages. The arbitrator shall render a “reasoned decision” within the meaning of the Commercial Arbitration Rules, which shall include findings of fact and conclusions of law. Any arbitration award may be entered in and enforced by a court in accordance with Section 14.5.2(d) (Arbitration).

(d)Any award to be paid by one Party to the other Party as determined by the arbitrator as set forth above under Section 14.5.2 (Arbitration) shall be promptly paid in Dollars free of any tax, deduction or offset; and any costs, fees or taxes incident to enforcing the award shall, to the maximum extent permitted by law, be charged against the Party resisting enforcement. Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Section 14.5 (Dispute Resolution), and agrees that, subject to the Federal Arbitration Act, judgment may be entered upon the final award in a court of competent jurisdiction and that other courts may award full faith and credit to such judgment in order to enforce such award. With respect to money damages, nothing contained herein shall be construed to permit the arbitrator or any court or any other forum to award punitive or exemplary damages. By entering into this agreement to arbitrate, the Parties expressly waive any claim for punitive or exemplary damages. The only damages recoverable under this Agreement are compensatory damages.

(e)Each Party shall bear its own legal fees in connection with any arbitration procedure. The arbitrator may in his or her discretion assess the arbitrator’s cost, fees and expenses (and those of any expert hired by the arbitrator) against the Party losing the arbitration.

14.5.3 Injunctive Relief. Nothing in this Section 14.5 (Dispute Resolution) will preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding. Each Party further acknowledges and agrees that the restrictions set forth in Section 2.5 (Exclusivity), Article 4 (License Grants), Article 8 (Intellectual Property) and Article 12 (Confidentiality) are reasonable and necessary to protect the legitimate interests of the other Party and that such other Party would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any provision of such Section or Article may result in irreparable injury to such other Party for which there

49

will be no adequate remedy at law. In the event of a breach or threatened breach of any provision of such Section or Articles, the non-breaching Party shall be authorized and entitled to seek from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, specific performance, and an equitable accounting of all earnings, profits, and other benefits arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which such non-breaching Party may be entitled in law or equity. Both Parties agree to waive any requirement that the other (a) post a bond or other security as a condition for obtaining any such relief, and (b) show irreparable harm, balancing of xxxxx, consideration of the public interest, or inadequacy of monetary damages as a remedy. For the avoidance of doubt, nothing in this Section 14.5.3 (Injunctive Relief) shall otherwise limit either Party’s opportunity to cure a material breach as permitted in accordance with Article 13 (Term & Termination).

14.5.4 Confidentiality. The arbitration proceedings shall be confidential and the arbitrator shall issue appropriate protective orders to safeguard each Party’s Confidential Information. Except as required by applicable Law, no Party shall make (or instruct the arbitrator to make) any public announcement with respect to the proceedings or decision of the arbitrator without prior written consent of the other Party. The existence of any dispute submitted to arbitration, and any award, shall be kept in confidence by the Parties and the arbitrator, except as required in connection with the enforcement of such award or as otherwise required by applicable Law. Notwithstanding the foregoing, each Party shall have the right to disclose information regarding the arbitration proceedings to the same extent as it may disclose Confidential Information of the other Party under Article 12 (Confidentiality).

14.5.5 Survival. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason.

14.5.6 Patent and Trademark Disputes. Notwithstanding Section 14.5.2 (Arbitration), and without prejudice to CytomX’s rights pursuant to Section 13.2.3 (CytomX Patent Challenge) or Moderna’s rights pursuant to Section 13.3.3(b) (Other Termination for Cause), any dispute, controversy or claim relating to the inventorship, scope, validity, enforceability or infringement of any patents Covering, or the scope, validity, enforceability or infringement of any trademark used in connection with, the manufacture, use, importation, offer for sale or sale of Licensed Products shall be submitted to a court of competent jurisdiction in the country in which such patent or trademark rights were granted or arose.

Neither this Agreement nor any of the rights or obligations created herein may be assigned by either Party, in whole or in part, without the prior written consent of the other Party, not to be unreasonably withheld, conditioned or delayed, except that either Party shall be free to assign this Agreement (a) to an Affiliate of such Party (for so long as such Affiliate remains an Affiliate); provided that such Party shall remain liable and responsible to the other Party for the performance and observance of all such duties and obligations by such Affiliate, or (b) in connection with any sale of all or substantially all of the assets of the Party to a Third Party, whether by merger, consolidation, divestiture, restructure, sale of stock, sale of assets or otherwise (a “Sale Transaction”; such Third Party, a “Third Party Acquirer”); provided that the party to which this Agreement is assigned expressly agrees in writing to assume and be bound by all obligations of the assigning Party under this Agreement, and provided, further, that if any such assignment by a paying Party would result in withholding or other similar taxes becoming due on payments to a non-paying Party under this Agreement (which withholding or other similar taxes would not have been due if the assignment did not occur), then any such assignment will require prior written consent absent an express agreement by the paying Party or the assignee to pay or reimburse the non-paying Party for any increase in such taxes resulting from such assignment that are not deductible or creditable by the non-paying Party under applicable Law, such consent not to be unreasonably withheld, conditioned or delayed. A copy of such written agreement by such assignee shall be provided to the non-assigning Party within [***] of execution of such written agreement.

Section 14.11Waivers. A Party’s consent to or waiver, express or implied, of any other Party’s breach of its obligations hereunder shall not be deemed to be or construed as a consent to or waiver of any other breach of the same or any other obligations of such breaching Party. A Party’s failure to complain of any act, or failure to act, by the other Party, to declare the other Party in default, to insist upon the strict performance of any obligation or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof, no matter how long such failure continues, shall not constitute a waiver by such Party of its rights hereunder, of any such breach, or of any other obligation or condition. A Party’s consent in any one instance shall not limit or waive the necessity to obtain such Party’s consent in any future instance and in any event no consent or waiver shall be effective for any purpose hereunder unless such consent or waiver is in writing and signed by the Party granting such consent or waiver.

Section 14.12Performance by Affiliates. Each Party may use one (1) or more of its Affiliates to perform its obligations and duties hereunder and such Affiliates are expressly granted certain rights herein; provided that each such Affiliate shall be bound by the corresponding obligations of such Party and such Party shall remain liable hereunder for the prompt payment and performance of all of their respective obligations hereunder.

Section 14.13Force Majeure. Each Party shall be excused from the performance of its obligations under this Agreement to the extent that such performance is prevented by Force Majeure (defined below) and the nonperforming Party promptly provides notice of such prevention to the other Party. Such excuse shall be continued so long as the condition constituting Force Majeure continues. The Party affected by such Force Majeure also shall notify the other Party of the anticipated duration of such Force Majeure, any actions being taken to avoid or minimize its effect after such occurrence, and shall take reasonable efforts to remove the condition constituting such Force Majeure. For purposes of this Agreement, “Force Majeure” shall mean conditions beyond the control of the Parties, including acts of God, acts of terrorism, voluntary or involuntary compliance with any Law of any Governmental Authority, embargoes, insurrections, war, acts of war (whether war be declared or not), shortages, epidemics, pandemics, quarantines, labor strikes, lock-outs or other labor disturbances (whether involving the workforce of the non-performing Party or of any other Person), civil commotion, riots, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, hurricane, storm, flood, or like catastrophe, or delays in acting by any Governmental Authority (except to the extent such delay results from the breach by the nonperforming Party or any of its Affiliates of any term or condition of this Agreement). The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use Commercially Reasonable Efforts to remedy its ability to perform. When such circumstances arise, the Parties shall negotiate in good faith any modifications of the terms of this Agreement that may be necessary or appropriate in order to arrive at an equitable solution.

Section 14.14No Third Party Beneficiaries. Nothing in this Agreement shall be construed as giving any Person, other than the Parties and their successors and permitted assigns, any right, remedy or claim under or in respect of this Agreement or any provision hereof, except for the provisions of Article 10 (Indemnification) (with respect to which the persons to which Article 10 (Indemnification) applies shall be Third Party beneficiaries for Article 10 (Indemnification) only in accordance with the terms and conditions of Article 10 (Indemnification)).

Section 14.15Headings; Exhibits; Appendices. Article and Section headings used herein are for convenient reference only, and are not a part of this Agreement, and in no way define, describe, extend, or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. All Exhibits are incorporated herein by this reference.

Section 14.16Interpretation. Except where the context otherwise requires, wherever used, the singular shall include the plural, the plural the singular, and the use of any gender shall be applicable to all genders and the word “or” is used in the inclusive sense (and/or). The term “including,” “include,” or “includes” as used herein means including, without limiting the generality of any description preceding such term. The word “will” shall be construed to have the same meaning and effect as the word “shall”. The words “herein”, “hereof” and “hereunder” and words of similar import will be construed to refer to this Agreement in its entirety and not to any particular provision hereof. The language in all parts of this Agreement shall be deemed to be the language mutually chosen by the Parties. Whenever this Agreement refers to a number of days, unless otherwise specified, such number refers to calendar days. The Parties and their counsel have cooperated in the drafting and preparation of this Agreement, and this Agreement therefore shall not be construed against any Party by virtue of its role as the drafter thereof.

Section 14.17Counterparts Electronic or Facsimile Signatures. This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one instrument. This Agreement may be executed and delivered electronically or by facsimile and upon such delivery such electronic or facsimile signature will be deemed to have the same effect as if the original signature had been delivered to the other Party.
