that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and estimated amount of such Loss (to the extent that the nature and amount of such Loss is known at such
time). The Indemnified Party will furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims. 

(d)    Defense, Settlement, Cooperation and Expenses. 

(i)    Control of Defense. At its option, the indemnifying Party may assume the defense of any Third Party Claim by
giving written notice to the Indemnified Party within [***] days after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party will not be construed as
an acknowledgment that the indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor will it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified
Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party (the
indemnifying Party will consult with the Indemnified Party with respect to a possible conflict of interest of such counsel retained by the indemnifying Party). In the event the indemnifying Party assumes the defense of a Third Party Claim, the
Indemnified Party will immediately deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Third Party Claim. Should the indemnifying Party assume the
defense of a Third Party Claim, except as provided in Section 12.6(d)(ii), the indemnifying Party will not be liable to the Indemnified Party for any legal costs or expenses subsequently incurred by such Indemnified Party in connection with the
analysis, defense or settlement of the Third Party Claim. [***] 
 (ii)    Right to Participate in Defense.
Without limiting Section 12.6(d)(i), any Indemnified Party will be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment
will be at the Indemnified Party’s own cost and expense unless [***]. 
 (iii)    Settlement. With respect
to any Third Party Claims that relate solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely
affecting the business of the Indemnified Party in any manner, and as to which the indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the


  
 32 














 A&R OPTION AGREEMENT 

 

 
indemnifying Party will have the sole right to agree to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its
sole discretion, will deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 12.6(d)(i), the
indemnifying Party will have authority to agree to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (such consent not to be unreasonably
withheld, delayed or conditioned). The indemnifying Party will not be liable for any settlement or other disposition of a Loss by an Indemnified Party that is reached without the prior written consent of the indemnifying Party. Regardless of whether
the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party will admit any liability with respect to or settle, compromise or discharge, any Third Party Claim without the prior written consent of the
indemnifying Party, such consent not to be unreasonably withheld, delayed or conditioned. 

(iv)    Cooperation. If the indemnifying Party chooses to defend or prosecute any Third Party Claim, the
Indemnified Party will, and will cause each other Indemnified Party to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery
proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation will include access during normal business hours afforded to indemnifying Party to, and reasonable retention by the Indemnified Party
of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any
material provided hereunder, and the indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket costs and expenses in connection
therewith. 
 (v)    Costs and Expenses. Except as provided above in this Section 12.6(d), the reasonable
and verifiable costs and expenses, including attorneys’ fees and expenses, incurred by the Indemnified Party in connection with any claim will be reimbursed on a Calendar Quarter basis by the indemnifying Party, without prejudice to the
indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party. 

 

	13.	 Term and Termination. 



13.1    Option Agreement Term. This A&R Option Agreement will commence as of the Amendment Effective Date and on
such date will replace and supersede the Original Option Agreement in its entirety; provided that [***]. The term of this A&R Option Agreement, unless sooner terminated in accordance with the terms hereof or by mutual written consent, will be
deemed to have commenced on the Signing Date and will continue until the entire Exercise Price for each Optioned Product Candidate (and associated Development Pool Candidates) is paid in full (the “Option Agreement Term”). 

13.2    Termination by Moderna. Moderna will have the right to terminate this A&R Option Agreement in full upon
delivery of written notice to AstraZeneca in the event of any material breach by AstraZeneca of any terms and conditions of this A&R Option Agreement [***], 

  
 33 














 A&R OPTION AGREEMENT 

 

 
provided, that to the extent that any such breach is limited to Collaboration mRNA Constructs [***] a particular Research Polypeptide or Development Polypeptide, Moderna will have the
right to terminate this A&R Option Agreement only with respect to such Collaboration mRNA Constructs, and (a) such Collaboration mRNA Constructs will become Discontinued Product Candidates, (b) the Polypeptide [***] such Collaboration
mRNA Constructs will become a Discontinued Polypeptide and (c) the Research Target [***] such Discontinued Polypeptide will become a Discontinued Research Target unless for such Research Target there is an Optioned Product Candidate [***] a
Development Polypeptide for such Research Target. For clarity, for the purposes of such discontinuance, [***]. Notwithstanding the foregoing, any such termination under this Section 13.2 will not be effective if such breach has been cured
within [***] days after written notice thereof is given by Moderna to AstraZeneca specifying the nature of the alleged breach (or, if such default cannot be cured within such [***]-day period, such longer
period as reasonably required to cure such breach, provided that AstraZeneca commences actions to cure such default within such [***]-day period and thereafter diligently continues such actions); provided,
that to the extent such material breach involves the failure to make an undisputed payment when due, such breach must be cured within [***] days after written notice thereof is given by Moderna to AstraZeneca. [***] 

13.3    Termination by AstraZeneca. 

(a)    Breach. AstraZeneca will have the right to terminate this A&R Option Agreement in full upon delivery of
written notice to Moderna in the event of any material breach by Moderna of any terms and conditions of this A&R Option Agreement [***], provided, that to the extent that any such breach is limited to a particular Polypeptide (and
Collaboration mRNA Constructs [***] such Polypeptide), AstraZeneca will have the right to terminate this A&R Option Agreement only with respect to such Polypeptide (and Collaboration mRNA Constructs [***] such Polypeptide). Notwithstanding the
foregoing, any such termination under this Section 13.3(a) will not be effective if such breach has been cured within [***] days after written notice thereof is given by AstraZeneca to Moderna specifying the nature of the alleged breach (or, if
such default cannot be cured within such [***]-day period, such longer period as reasonably required to cure such breach, provided that Moderna commences actions to cure such default within such [***] period
and thereafter diligently continues such actions); provided, that to the extent such material breach involves the failure to make an undisputed payment when due, such breach must be cured within [***] days after written notice thereof is
given by AstraZeneca to Moderna. [***] 
 (b)    Discretionary Termination. AstraZeneca will have the right to
terminate this A&R Option Agreement in full ninety (90) days after delivery of written notice to Moderna if the Executive Officer of AstraZeneca concludes due to scientific, technical, regulatory or commercial reasons, including [***]. 

13.4    Alternative to Termination Under Section 13.3(a). If AstraZeneca has the right to
terminate this A&R Option Agreement or this A&R Option Agreement with respect to a particular Polypeptide that is [***] an Optioned Product Candidate (or Subject Construct or Product) under Section 13.3(a) (including expiration of all
applicable cure periods thereunder), in lieu of exercising such termination right, AstraZeneca may elect once by written notice to Moderna before the end of such applicable cure period to have this A&R Option Agreement continue in full force and
effect, in which case the following will apply: 

  
 34 














 A&R OPTION AGREEMENT 

 

 (a)    Starting immediately after the end of such applicable cure period,
any payments for Contingent Event Option Exercise Payment and Option Exercise Earn-Out payments hereunder payable following such date that AstraZeneca has the right to terminate this A&R Option Agreement
under Section 13.3(a) will be reduced by [***], provided that such reduction will not apply if and to the extent [***]; provided that if such right of termination is limited to a particular Optioned Product, Subject Construct or Product,
then such [***] reduction will apply to such Optioned Product Candidate, Subject Construct or Product and will not apply more generally. 

(b)    The following provisions will cease to apply: [***] of the Product Commercialization Schedule; provided that [***].

 13.5    Effects of Termination or Expiration. Upon termination or expiration of this A&R Option Agreement
for any reason: 
 (a)    The license grants (including Section 3.1) will terminate, other than [***]; 

(b)    Any unpaid Exercise Price attributable to those Optioned Product Candidate (and associated Development Pool
Candidates) will remain due and payable to Moderna, pursuant to the applicable Schedule A; and 

(c)    All unexercised Options will automatically terminate; 

Provided that, in the event that either Party terminates this A&R Option Agreement with respect to a particular Optioned Product Candidate, Subject
Construct or Product, the provisions of Section 6.3 of the Product Commercialization Schedule will apply. 

13.6    Survival. In addition to the termination consequences set forth in Section 13.5, the following
provisions will survive termination or expiration of this A&R Option Agreement: [***]. Termination or expiration of this A&R Option Agreement will not relieve the Parties of any liability or obligation which accrued hereunder prior to the
effective date of such termination or expiration nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this A&R Option Agreement nor prejudice either
Party’s right to obtain performance of any obligation. All other rights and obligations will terminate upon expiration of this A&R Option Agreement. 

13.7    Integrated Agreements. The Parties acknowledge that the Transaction Agreements, together, constitute an
integrated set of agreements entered into as part of the same transaction that collectively govern the subject matter covered by the Transaction Agreements. Early termination of any one of the Transaction Agreements without the others would
fundamentally alter the intended allocation of rights and obligations intended by the Parties in entering into the Transaction Agreements. Thus, if a Party (or its bankruptcy trustee) has the right to reject any of the Transaction Agreements under
the U.S. Bankruptcy Code or any analogous provision under any other law in any country outside the United States, such Party (or the applicable bankruptcy trustee) will either reject all of the Transaction Agreements or assume all of the Transaction
Agreements, but may not reject one Transaction Agreement without rejecting the others.

may be executed in one or more counterparts, each of which will be deemed an original, and all of which together will be deemed to be one and the same instrument. Facsimile or PDF execution and delivery of this A&R Option Agreement by either

the benefit of and be binding upon the Parties, their Affiliates, and their respective lawful successors and assigns. 

14.13    Assignment. This A&R Option Agreement may not be assigned by either Party, nor may either Party
delegate its obligations or otherwise transfer any rights created by this A&R Option Agreement, except as expressly permitted hereunder or otherwise without the prior written consent of the other Party, which consent will not be unreasonably

assets or that portion of its business pertaining to the subject matter of this A&R Option Agreement, or any Business Combination of such Party. Notwithstanding the foregoing, neither Party may assign this A&R Option Agreement unless such
assignment also includes an assignment of all of the Transaction Agreements to the same Affiliate or Third Party successor, as applicable. The rights and obligations of the Parties under this A&R Option Agreement will be binding upon and inure
to the benefit of the successors and permitted assigns of the Parties, and the name of a Party appearing herein will be deemed to include the name of such Party’s successors and permitted assigns to the extent necessary to carry out the intent

be amended, supplemented, or otherwise modified only by means of a written instrument signed by both Parties; provided that any unilateral undertaking or waiver made by one Party in favor of the other will be enforceable if undertaken in a
writing signed by the Party to be charged with the undertaking or waiver. Any waiver of any rights or failure to act in a specific instance will relate only to such instance and will not be construed as an agreement to waive any rights or fail to
act in any other instance, whether or not similar. 
 14.15    Severability. In the event that any provision of
this A&R Option Agreement will, for any reason, be held to be invalid or unenforceable in any respect, and if the rights or obligations of either Party under this A&R Option Agreement will not be materially and adversely affected thereby,
(a) such provisions will be given no effect by the Parties and will not form part of this A&R Option Agreement, (b) all other provisions of this A&R Option Agreement will remain in full force and effect, and (c) the Parties

product sold by a Third Party not licensed or otherwise authorized by or on behalf of AstraZeneca or any of its Affiliates or Sublicensees (a) that is a “biological product” (as defined in Section 351(i)(1) of the PHSA) that is
subject to a license for administration to humans under Section 351(a) or 351(k) of the PHSA and (i) contains an active ingredient that is the same as the active ingredient of such Product (including any mRNA Constructs therein) or

illegal for AstraZeneca (or any other Selling Party) to transfer, or have transferred on its behalf, payments owed Moderna under this Schedule A, AstraZeneca will promptly notify Moderna of the conditions preventing such
transfer and such payments will be deposited in local currency in the relevant country to the credit of Moderna in a recognized banking institution designated by Moderna or, if none is designated by Moderna within a period of [***] days, in a
recognized banking institution selected by AstraZeneca or another Selling Party, as the case may be, and identified in a written notice given to Moderna. 

(f)    Interest Due. If any payment due to either Party under this Schedule A is overdue
(and is not subject to a good faith dispute), then such paying Party will pay interest thereon [***] at an annual rate [***] of the lesser of (i) [***] and (ii) [***], such interest to run from the date upon which payment of such sum became due
