generated by or jointly with such collaborators of CureVac, i.e., a non-exclusive, royalty-free, and sublicensable license under the applicable Know-How and Patents generated (if any).

(a)By Arcturus. Subject to the terms and conditions of this Agreement, Arcturus hereby grants to CureVac a worldwide, non-exclusive license under the Arcturus LMD Technology, including the right to grant sublicenses, limited in accordance with this Section 3.5, to research and pre-clinically develop (including the right to manufacture for such purposes), but expressly without the right to clinically develop or commercialize (including the right to manufacture for such purpose) except with the prior written consent of Arcturus) and in any event solely to the extent necessary:

(b)By CureVac.

(c)No Other Licenses. No license or right is or will be created or granted hereunder by implication, estoppel or otherwise. All licenses and rights are or will be granted only as expressly provided in this Agreement.

Development and Option Agreement between CureVac AG and Arcturus Therapeutics Inc

4.1Generally. CureVac will select the Targets that will be the subject of the Works to be performed as part of a Program from the Reserved Target List. CureVac shall have the right, but not the obligation, to reserve Targets (or replace a Reserved Target with a new Target) in accordance with this Article 4.

(a)Pre-existing Restrictions. Arcturus shall maintain at the Escrow Agent an updated monthly (as of the final day of each month) list of Targets that are subject to Pre-Existing Restrictions (the "Restricted Target List"). The Restricted Target List will identify whether the Pre-Existing Restrictions are exclusive, non-exclusive or co-exclusive. Arcturus represents, warrants and covenants to CureVac that (i) the Restricted Target List is and will at all times be accurate in accordance with this Section 4.2(a); and (ii) Arcturus or the Escrow Agent will not add any Reserved Targets to the Restricted Target List or grant to any Third Party any licenses or options under the Arcturus LMD Technology with respect to the then current Reserved Target List that would preclude Arcturus from entering into a License Agreement with respect to such Reserved Target as set forth herein.

(i)

If CureVac desires to include a Target as a Reserved Target hereunder, CureVac will notify the Escrow Agent in writing (with contemporaneous information in writing to Arcturus about the notification to the Escrow Agent) of the Targets for potential inclusion on the Reserved Target List, which notice will provide (i) the information on the Target Reservation Request Form attached hereto as Exhibit 4.2; and (ii) the identity of each Reserved Target (if any) that CureVac desires to remove as a Reserved Target (each such notice, a "Target Notice"). For clarity, the Target Notices shall not include more Targets than the Maximum Targets then available (taking into consideration any removed Targets previously reserved) and shall be deemed to be a request for an exclusive license at the outset unless there is a Pre-Existing Restriction. For clarity, CureVac’s rights to enter into a Non-Exclusive License Agreement shall apply only if the Pre-Existing Restriction permits a non-exclusive license right to such proposed Reserved Target.

If, as of the date of CureVac’s Target Notice for a Target, such Target is not listed on the Restricted Target List, then such Target will become a Reserved Target and will be added to the Reserved Target List subject to the Concurrent Reserved List Limits set forth in subsection (d) below. To the extent that the Pre-Existing Restriction is non-exclusive, then such Target may be added by CureVac to Reserved Target List, but CureVac shall only have the option to enter into a Non-Exclusive License Agreement.

(d)Concurrent Reserved List Limits and Removal of Targets. The following concurrent reserved list limits will apply to all Reserved Targets ("Concurrent Reserved List Limits").

such reduction in the total Targets applying from and after the date of exercise of an Option.

4.3Expiration of Pre-Existing Restrictions. If any Pre-Existing Restrictions identified in a Target Response Notice that precluded Arcturus from granting CureVac a license (whether or not CureVac has elected to designate such Target on the Reserved Target List on a non-exclusive basis subject to the Pre-Existing Restriction) under the Arcturus LMD Technology later expire or otherwise are modified or terminate such that Arcturus is no longer precluded under the terms of the applicable Third Party agreement from granting a license to CureVac with respect to such Target, the Escrow Agent will notify CureVac of such event and CureVac will have an exclusive option, for a period of […***…] days following delivery of notice to CureVac, to add (or extend its rights as identified by the Escrow Agent with respect to) such Target to the Reserved Target List as a Reserved Target in accordance with Section 4.2(c), subject to the Concurrent Reserved List Limits. For clarity, CureVac will at all times thereafter have the right to provide a Target Notice for such Target to the Escrow Agent pursuant to Section 4.2(b) but such Target Notice will be subject to any intervening Pre-Existing Restrictions.

4.4Escrow Agent. Arcturus shall ensure that the Escrow Agent meets the requirements set forth herein. All costs and expenses incurred through the Escrow Agent will be borne by Arcturus.

(a)From the period commencing on the Effective Date and ending on the expiration of the Term (the "Option Period"), CureVac will have a total of […***…] options (each, an "Option"), on a Reserved Target-by-Reserved Target basis, to enter into a maximum of […***…] licenses under the Arcturus LMD Technology with respect to the development, manufacture and commercialization of Licensed Products containing mRNA Constructs intended to express such Reserved Target in the form of the License Agreement, provided, however, that

(b) CureVac may exercise each such Option by providing to Arcturus, prior to the expiration of the Term, irrevocable written notice of Option exercise, setting forth the particular Reserved Target which is intended to be expressed by the Licensed Products (each such notice, an "Option Notice"). A separate Option Notice and Option Exercise Fee will be required for each License Agreement with respect to which CureVac exercises an Option pursuant to this Section 5.1, and CureVac will pay to Arcturus the Option Exercise Fee for each such License Agreement as set forth in Section 5.3. If not exercised prior to the expiration of the Term, the Options granted to CureVac under this Article 5 will terminate in full and will no longer be exercisable. In the event that CureVac terminates a license(s) during the Term, the Target(s) subject to the license(s) will be removed from the Reserved Target List and the number of remaining Options and/or License Agreements shall be reduced by one (1) (i.e., the exercise of an Option reduces the total number of Options remaining by one regardless of whether CureVac elects to continue such License Agreement in effect).

(c)In the event that CureVac terminates a License Agreement during the Term, no additional or replacement Options shall be granted or reinstated and the Target(s) subject to such license(s) will no longer be available as a Target pursuant to this Agreement.

5.2CureVac’s Exercise of Option. As soon as practicable following CureVac’s delivery of an Option Notice to Arcturus but in any event within […***…] Business Days, CureVac and Arcturus will enter into a License Agreement with respect to the Reserved Target for which such Option Notice is provided, provided, however, that if the Parties fail to prepare the appendices to the License Agreement in accordance with Section 5.1(a)(ii) within […***…] Business Days following CureVac’s delivery of an Option Notice to Arcturus, the License Agreement with respect to the Reserved Target shall nevertheless enter into force (including payment obligations of CureVac in accordance with the terms of the License Agreement) and the Parties shall complete the appendices as soon as practicable thereafter.

5.3Option Exercise Fee. If CureVac exercises its Option for a Rare Disease Target pursuant to Section 5.1, CureVac shall pay an Option Exercise Fee of […***…]; and if CureVac exercises its Option for a Non-Rare Disease Target pursuant to Section 5.1, CureVac shall pay an Option Exercise Fee of […***…], hereinafter both the "Option Exercise Fee". Within […***…] Business Days after exercise of the Option for Licensed Product(s), Arcturus will issue an invoice to CureVac for the Option Exercise Fee. Each such payment will be subject to entry into the License Agreement and due within […***…] days after CureVac's receipt of such invoice from Arcturus.

5.4Co-Development Agreement. For clarification, the selection of any program under the Co-Development Agreement shall not constitute the exercise of an Option in accordance with this Section 5, and, accordingly, no Option Exercise Fee will be payable and any paid Option Exercise Fee shall credited against any other payments by CureVac applied first to any outstanding payment obligations to Arcturus, and to the extent any remaining amounts remain creditable, then to the next due future payment obligations.

5.5Enablement. Arcturus will (a) with respect to any Reserved Targets, during the Term remain entitled to grant to CureVac the licenses to the Patents and the Know-How within the Arcturus Background Technology under a License Agreement, and (b) subject to the unrestricted rights of Arcturus and its Affiliates to grant to a Third Party a non-exclusive, co-

exclusive or an exclusive license or option with respect to a Target, use reasonable efforts to allow the potential for License Agreements to be available for Targets identified by CureVac to Arcturus for research and for election to become a Reserved Target pursuant to this Agreement during the Term.

6.1Disclosure of Program Know-How. Each Party will promptly (and at least on a Calendar Quarterly basis) disclose to the other Party any Program Know-How that is created, conceived or reduced to practice by or on behalf of such Party and owned by the other Party pursuant to Section 6.2(c), and will provide such documentation regarding the Program Know-How as such other Party may reasonably request.

8.5No Consequential Damages. Notwithstanding anything in this Agreement or otherwise, neither Party will be liable to the other or any Third Party with respect to any subject matter of this Agreement for any indirect or consequential damages, provided that this Section 8.5 will not apply to breaches of Article 6 or 7 or the Parties’ indemnification rights or obligations under Section 8.7, or in the event of willful misconduct.

8.6Performance by Others. The Parties recognize that each Party may perform some or all of its obligations under this Agreement through Affiliates, permitted subcontractors or other permitted Third Parties, provided, however, that each Party will remain fully responsible and liable for the performance by its Affiliates and/or permitted subcontractors and Third Parties and will cause its Affiliates, permitted subcontractors or other permitted Third Parties to comply with the provisions of this Agreement in connection therewith.

(a)Indemnification by Arcturus. Arcturus will indemnify CureVac, its Affiliates and their respective directors, officers, employees, Third Party licensors and agents, and their respective successors, heirs and assigns (collectively, "CureVac Indemnitees"), and defend and hold each of them harmless, from and against any and all losses, damages, liabilities, costs and expenses (including reasonable attorneys’ fees and expenses) (collectively, "Losses") in connection with any and all suits, investigations, claims or demands of Third Parties (collectively, "Third Party Claims") against the CureVac Indemnitees to the extent arising from or occurring as a result of:

(i) the breach of any representation or warranty by Arcturus under this Agreement; or (ii) any gross negligence or willful misconduct on the part of any Arcturus Indemnitee; or (iii) any alleged infringement or misappropriation of Patents or other intellectual property rights by CureVac in the conduct of the Work Plan based solely on CureVac’s use of Arcturus LMD Technology as permitted hereunder (excluding, for clarity, infringement of Patents, Know-How or Materials covering CureVac Technology used by CureVac in the performance of the Work Plan), except in each of cases (i)-(iii) to the extent arising from or occurring as a result of the gross negligence or willful misconduct on the part of a CureVac Indemnitee or CureVac’s breach of this Agreement.

(b)Indemnification by CureVac. CureVac will indemnify Arcturus, its Affiliates and their respective directors, officers, employees and agents, and their respective successors, heirs and assigns (collectively, "Arcturus Indemnitees"), and defend and hold each of them harmless, from and against any and all Losses in connection with any and all Third Party Claims against Arcturus Indemnitees to the extent arising from or occurring as a result of: (i) the breach by CureVac of any representation or warranty under this Agreement; or (ii) any gross negligence or willful misconduct on the part of any CureVac Indemnitee; or (iii) any alleged infringement or misappropriation of Patents or other intellectual property rights by Arcturus in the conduct of the Work Plan based solely on Arcturus’ use of CureVac Technology as permitted hereunder (excluding, for clarity, infringement of Arcturus LMD Technology used by Arcturus in the performance of the Work Plan), except in each of cases (i)-(iii) to the extent arising from or occurring as a result of the gross negligence or willful misconduct on the part of an Arcturus Indemnitee or Arcturus’ breach of this Agreement.

(c)Notice of Claim. All indemnification claims provided for in subsections (a) and (b) above will be made solely by such Party to this Agreement (the "Indemnified Party"). The Indemnified Party will promptly notify the indemnifying Party (an "Indemnification Claim Notice") of any Losses or the discovery of any fact upon which the Indemnified Party intends to base a request for indemnification under subsections (a) or (b) above but in no event will the indemnifying Party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice

Development and Option Agreement between CureVac AG and Arcturus Therapeutics Inc

must contain a description of the claim and the nature and 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.

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 such legal counsel and 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 as soon as practicable 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. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless the Indemnified Party from and against the Third Party Claim, the Indemnified Party will reimburse the indemnifying Party for any and all costs and expenses (including reasonable attorneys’ fees and costs of suit) and any Third Party Claims incurred by the indemnifying Party in its defense of the Third Party Claim.

Development and Option Agreement between CureVac AG and Arcturus Therapeutics Inc

to injunctive or other relief or otherwise adversely affecting the business, Patents or Technology 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 indemnifying Party will have the sole right to consent 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 subsection (i) above, the indemnifying Party will have authority to consent 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 (which consent will not be unreasonably withheld, conditioned or delayed). 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 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.

(iv)

Cooperation. Regardless of whether the indemnifying Party chooses to defend any Third Party Claim, the Indemnified Party will, and will use Diligent Efforts to 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 at the indemnifying Party’s expense. Such cooperation will include access during normal business hours afforded to the indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making indemnified parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket costs and expenses in connection therewith.

8.8Insurance. Each Party will maintain at its sole cost and expense, an adequate liability insurance or self-insurance program to protect against potential liabilities and risk

Development and Option Agreement between CureVac AG and Arcturus Therapeutics Inc

arising out of activities to be performed under this Agreement and any agreement related hereto and upon such terms (including coverages, deductible limits and self-insured retentions) as are customary in the respective industry of such Party for the activities to be conducted by such Party under this Agreement. The coverage limits set forth in any such programs or policies will not create any limitation on a Party’s liability to the other under this Agreement.

(a)This Agreement will commence as of the Effective Date and, unless sooner terminated or extended in accordance with the terms hereof or by mutual written consent, will continue for a period of eight (8) years (the "Initial Term", as may be extended pursuant to Section 9.1(b), the “Term”).

(b)Not later than sixty (60) days prior to the expiration of the Initial Term, CureVac shall have the option to extend the Term on an annual basis for up to three (3) years, by providing written notice to Arcturus, subject to payment by CureVac to Arcturus of a non-refundable annual extension fee of […***…], payable within […***…] Business Days after exercise of such option.

(c)The Parties agree that this Agreement and the Co-Development Agreement relate to different projects and, therefore, the validity, term and termination of this Agreement shall be independent from the validity, term and termination of the Co-Development Agreement.

(a)Breach, Change of Control. CureVac will have the right to terminate this Agreement in full or on a Program-by-Program basis upon delivery of written notice to Arcturus in the event of

(A)of any terms and conditions of this Agreement, provided that such breach has not been cured within sixty (60) days after written notice thereof is given by CureVac to Arcturus specifying in reasonable detail the nature of the alleged breach; or

(B)in particular the failure of the Escrow Agent to send the Target response notice within the period provided for in Section 4.2(c)(i), provided that such failure has not been cured neither within a first cure period of five (5) Business Days after written notice thereof is given by CureVac to Arcturus nor within a second cure period of five (5) Business Days after written notice of the lapse of the first cure period is given by CureVac to Arcturus, or

In the event of a termination of this Agreement or a Program under this subsection, (i) the JDC will be disbanded or, if applicable, cease to be responsible for the terminated Programs, (ii) Arcturus will receive no further Arcturus FTE funding (if applicable, for the terminated Programs), and (iii) Arcturus will conduct a technology transfer of Arcturus Technology existing at the time of such transfer and provide necessary licenses to CureVac or its Third Party designee each as reasonably necessary for CureVac or such Third Party designee to complete the conduct of a Program, and (iv) the Option Exercise Fee and the payments under the License Agreement(s) (if

applicable, in relation to the terminated Programs) will be reduced by […***…]%. For avoidance of doubt, termination of the Agreement or a Program will not terminate CureVac’s reservation of Reserved Targets or the Options subject to the payments associated therewith. For clarity, except in cases of willful misconduct, the remedy set forth in this Section 9.2(a) shall be the sole and exclusive remedy of CureVac under this Agreement (i.e., without limitation of any remedies that may be separately available under any License Agreement) in the event that CureVac elects to terminate a Program but otherwise continue the Agreement in effect.

In the event of a Change of Control of Arcturus, CureVac shall decide, no later than the later of: (i) ten (10) Business Days’ written notice following the receipt of a written notification that the closing date of such Change of Control has occurred or (ii) […***…] months written notice following the receipt of a written notification that the signing date of such Change of Control has occurred, to (a) terminate this Agreement, (b) to continue this Agreement and elect (as set forth in such written notice) to have the JDC disbanded and Arcturus to undertake a technology transfer and provide necessary licenses to CureVac or its Third Party designee each as reasonably necessary for CureVac or such Third Party designee to complete the conduct of any then ongoing Programs in accordance with the Work Plan; or (c) continue the Agreement and receive reasonable assurance in writing from the acquirer that the CureVac Confidential Information is not shared with any other entities within the acquirer’s group that are not required to manage, perform and exercise Arcturus’ rights and obligations under this Agreement.

(b)Discretionary Termination. CureVac will have the right to terminate this Agreement in full at any time without cause by giving sixty (60) days’ prior written notice to Arcturus. Upon termination by CureVac pursuant to this subsection, CureVac will pay to Arcturus any amounts payable to Arcturus for any Work performed pursuant to the Work Plan up through the date of such termination, subject to Arcturus’ transfer of all deliverables under the Work Plan to CureVac.

9.3Termination by Arcturus. Arcturus will have the right to terminate this Agreement in full upon delivery of written notice to CureVac in the event of (i) any material breach by CureVac of any terms and conditions of this Agreement, provided that such breach has not been cured within sixty (60) days after written notice thereof is given by Arcturus to CureVac specifying in reasonable detail the nature of the alleged breach. CureVac hereby agrees that Arcturus is entitled to receive payment of any amounts payable to Arcturus pursuant to this Agreement, including amounts for any Work performed pursuant to the Work Plan, up through the date of such termination. For clarity, a breach by CureVac under this Agreement shall not constitute a breach under a License Agreement unless such breach is also separately a breach pursuant to such License Agreement.

9.4Termination Upon Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Arcturus or CureVac or their Affiliates are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to "intellectual property" as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that the Parties and their respective Affiliates and permitted Third Party sublicensees, as licensees of such rights under this Agreement, will retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code and any foreign counterparts thereto. Without limiting the Parties’ rights under Section 365(n) of the U.S Bankruptcy Code, if a case under U.S. Bankruptcy Code is commenced by or against a Party, the other Party shall be entitled to a copy of any and all such intellectual property and all embodiments of such intellectual property, and the same, if not in the possession of such other Party, shall be promptly delivered to it (i) before this Agreement is rejected by or on behalf of the bankrupt Party, within thirty (30) days after the other Party’s written request, unless the bankrupt Party, or its trustee or receiver, elects within thirty (30) days to continue to perform all of its obligations under this Agreement, or (ii) after any rejection of this Agreement by or on behalf of the bankrupt Party, if not previously delivered as provided under clause (i) above. All rights of the Parties under this Section 9.4 and under Section 365(n) of the U.S. Bankruptcy Code are in addition to and not in substitution of any and all other rights, powers, and remedies that each Party may have under this Agreement, under the U.S. Bankruptcy Code, and any other applicable Laws. The non-bankrupt Party shall have the right to perform the obligations of the bankrupt Party hereunder with respect to such intellectual property, but neither such provision nor such performance by the non-bankrupt Party shall release the bankrupt Party from any such obligation or liability for failing to perform it.

(a)CureVac under Sections 9.2 or 9.4, (i) Arcturus will terminate all Work in progress in an orderly manner as soon as practicable and transfer all deliverables under the Work Plan to CureVac in its Control in the state of such deliverable as of the effective date of termination; (ii) each of the Parties will return or destroy any Materials of the other Party in its Control, based upon written instructions from the other Party within […***…] days of the effective date of termination, unless such Material is necessary or useful for the exercise of a Party's rights or obligations under a License Agreement in which event the Party retaining the Material will notify the other Party of retention pursuant to the requirements of and subject to such License Agreement; and (iii) all rights and licenses pursuant to this Agreement except with respect to any then existing Programs (for which licenses to CureVac or its Third Party designee shall be granted to complete the Program and enter into a License Agreement under the terms of Section 9.2(a)(ii)) shall terminate and be of no further force and effect, it being understood that termination hereunder shall not affect any then existing License Agreement;

(b)Arcturus under Section 9.3, (i) CureVac will promptly pay Arcturus any monies due and owing Arcturus, as of the date of termination, for Work and Services actually performed and all expenses actually incurred as specified in the Work Plan as well as any amounts incurred for orderly wind down any then existing Third Party commitments entered into as of the date of notice of termination to perform the Work Plan; (ii) each of the Parties will return or destroy any Materials of the other Party in its Control, based upon written instructions from the other Party within […***…] days of the effective date of termination, unless such Material is necessary or useful for the exercise of a Party's rights or obligations under a License Agreement in which event the

Party retaining the Material will notify the other Party of retention pursuant to the requirements of and subject to such License Agreement; and (iii) all rights and licenses pursuant to this Agreement shall terminate and be of no further force and effect, it being understood that termination hereunder shall not affect any then existing License Agreement.

9.6Survival. In addition to the termination consequences set forth in Section 9.5, the following provisions will survive termination or expiration of this Agreement, as well as any other provision which by its terms or by the context thereof, is intended to survive such termination: Sections 1, 3.1(f) (to the extent a License Agreement is executed prior to the effective date of termination), 3.3(a), 6.2, 6.3, 7, 8.5, 8.7, 9.2, 9.5 , 9.6 and 10. Termination or expiration of this 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 Agreement nor prejudice either Party’s right to obtain performance of any obligation. All other rights and obligations will terminate upon expiration of this Agreement.

(a)Dispute Escalation. In the event of a dispute between the Parties, the Parties will first attempt in good faith to resolve such dispute by negotiation and consultation between themselves or the Program directors. In the event that such dispute is not resolved on an informal basis within […***…] days, either Party may, by written notice to the other, have such dispute referred to each Party’s Chief Executive Officer or his or her designee (who will be a senior executive with the appropriate authority to determine the matter for such Party), who will attempt in good faith to resolve such dispute by negotiation and consultation for a […***…] day period following receipt of such written notice

10.2Relationship of Parties. Nothing in this Agreement is intended or will be deemed to constitute a partnership, agency, employer-employee or joint venture relationship between the Parties.

(a)Waiver of Rule of Construction. Each Party has had the opportunity to consult with counsel in connection with the review, drafting and negotiation of this Agreement. Accordingly, the rule of construction that any ambiguity in this Agreement will be construed against the drafting party will not apply.

Development and Option Agreement between CureVac AG and Arcturus Therapeutics Inc

THIS AMENDMENT TO DEVELOPMENT AND OPTION AGREEMENT (this “Amendment”), dated as of May 3, 2018, is made by and between CureVac AG, a German stock corporation with offices at Paul-Ehrlich-Strasse 15, 72076 Tubingen, Germany (“CureVac”), and Arcturus Therapeutics Inc., a Delaware corporation with offices at 10628 Science Center Drive #200, San Diego, CA 92121, USA (“Arcturus”). Each of CureVac and Arcturus may be referred to herein as a “Party” or together as the “Parties”.

WHEREAS, the Parties are parties to that certain Development and Option Agreement, dated as of January 1, 2018 (the “Development and Option Agreement”);

WHEREAS, pursuant to Section 3.2 of the Development and Option Agreement, CureVac is responsible for funding up to […***…] scientists per year at Arcturus to perform the Work as defined and in accordance with the Work Plan for a period of up to […***…] months at the FTE costs;

WHEREAS, CureVac is now prepared to invest and commit to the full number of […***…] FTEs for the full period of […***…] months, provided Arcturus can provide security as to CureVac's access to the Technology generated in performance of the Work pursuant to the Development and Option Agreement; and

WHEREAS, CureVac and Arcturus desire to amend the Development and Option Agreement as provided in this Amendment in accordance with Section 10.11 of the Development and Option Agreement.

NOW, THEREFORE, in consideration of the foregoing and the promises and mutual agreements contained in this Amendment, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally bound, the Parties agree as follows:

“ (a) Arcturus hereby makes a final, binding irrevocable offer (the “Irrevocable Offer”) to CureVac to enter into, on the terms of, and subject to the conditions set forth in, the Exclusive License Agreement or, if the Reserved Target is only available on a non-exclusive basis, the Non-Exclusive License Agreement, on a Reserved Target-by-Target basis, a maximum of […***…] licenses under the Arcturus LMD Technology with respect to the development, manufacture and commercialization of Licensed Products containing mRNA Constructs intended to express such Reserved Target in the form of the License Agreement. Upon the execution of this Amendment, the Irrevocable Offer shall remain valid and legally binding on Arcturus and in effect, and the

Irrevocable Offer from Arcturus shall be irrevocable and open for acceptance from CureVac for the period commencing on the Effective Date and ending on the expiration of the Term (the “Offer Period”).”

(c)Section 5.1(b) of the Development and Option Agreement is hereby amended and restated in its entirety as follows:

“ (b) If, prior to the expiration of the Offer Period, CureVac delivers written notice to Arcturus of its intention to enter into a license for a Reserved Target, which such notice shall set forth the particular Reserved Target which is intended to be expressed by the Licensed Products (each such notice, an “Acceptance Notice”), then upon delivery thereof, for the Reserved Target set forth in such Acceptance Notice, the licenses and all other rights under the applicable License Agreement shall immediately be in effect without the requirement of either Party to execute any further documentation and there shall exist a legal, valid and binding obligation of Arcturus, enforceable against Arcturus in accordance with the terms of the Exclusive License Agreement or, if the Reserved Target set forth in such Acceptance Notice is only available on a non-exclusive basis, the Non-Exclusive License Agreement. A separate Acceptance Notice and Acceptance Fee will be required for each License Agreement with respect to which CureVac accepts the Irrevocable Offer pursuant to this Section 5.1, and CureVac will pay to Arcturus the Acceptance Fee for each such License Agreement as set forth in Section 5.3. In the event that CureVac terminations a license(s) during the Term, the Target(s) subject to the license(s) will be removed from the Reserved Target List and the number of License Agreements for which the Irrevocable Offer exists shall be reduced by one (1) (i.e. the delivery of an Acceptance Notice reduces the total number of License Agreements for which CureVac may accept the Irrevocable Offer by one regardless of whether CureVac elects to continue such License Agreement in effect).”

(d)Section 5.1(c) of the Development and Option Agreement is hereby amended and restated in its entirety as follows:

“ (c) In the event that CureVac terminates a License Agreement during the Term, the Targets subject to such license(s) will no longer be available as a Target pursuant to this Agreement.”

(e)Section 5.2 of the Development and Option Agreement is hereby amended and restated in its entirety as follows:

“5.2CureVac's Acceptance of Irrevocable Offer. As soon as practicable following CureVac's delivery of each Acceptance Notice to Arcturus, CureVac and Arcturus will prepare the appendices to the corresponding License Agreement. The License Agreement shall nevertheless enter into force (including payment obligations of CureVac in accordance with the terms of the License Agreement) upon delivery of the Acceptance Notice by CureVac.”

(f)Section 5.3 of the Development and Option Agreement is hereby amended and restated in its entirety as follows:

“5.3Acceptance Fee. If CureVac delivers an Acceptance Notice for a Rare Disease Target pursuant to Section 5.1, CureVac shall pay an Acceptance Fee of […***…] and if CureVac delivers an Acceptance Notice for a Non-Rare Disease Target pursuant to Section 5.1, CureVac shall pay an Acceptance Fee of […***…], hereinafter both the “Acceptance Fee”. On the […***…] it delivers an

Acceptance Notice, CureVac shall pay the applicable Acceptance Fee by wire transfer in immediately available funds to the bank account of Arcturus set forth on Schedule 3 (or such other bank account notified in writing to CureVac prior to such date).”

(g)Section 5.4 of the Development and Option Agreement is hereby amended and restated in its entirety as follows:

“5.4Co-Development Agreement. For clarification, the selection of any program under the Co-Development Agreement shall not constitute the delivery of an Acceptance Notice in accordance with this Section 5, and, accordingly, no Acceptance Fee will be payable and any paid Acceptance Fee shall be credited against any other payments by CureVac applied first to any outstanding payment obligations to Arcturus, and to the extent any remaining amounts remain creditable, then to the next due future payment obligations.”

(g)Definitions. Each of the following Sections of the Development and Option Agreement are hereby amended and restated in their entirety as “Intentionally Omitted.” : Section 1.35, Section 1.62, Section 1.64, Section 1.65, Section 1.66 and Section 1.67 The following Sections are inserted immediately following Section 1.94 of the Development and Option Agreement:

(v) In Section 6.4(c)(ii) of the Development and Option Agreement, the occurrence of “an Option Notice” in the first sentence is hereby replaced with “an Acceptance Notice”.

(vi) In Section 6.4(c)(iii) of the Development and Option Agreement, the occurrence of “to the Options” in the first sentence is hereby replaced with “pursuant to the Irrevocable Offer”.

Arcturus shall notify CureVac at least once every […***…] months of Patents that are added to the Arcturus Technology following the License Agreement Effective Date or any Patents that have been abandoned or discontinued in accordance with the terms of this License Agreement. Appendix 1.4 shall be deemed automatically updated to include any such added Patents, provided that with written notice to Arcturus, CureVac may elect upon […***…] days’ irrevocable written notice to Arcturus to exclude any particular Arcturus Technology Patents. Following any such written notice by CureVac, upon the expiration of the notice period the identified Arcturus Technology Patents that CureVac specifies for exclusion from this License Agreement will no longer be licensed to CureVac hereunder, and CureVac shall not have any rights (including rights pursuant to this Agreement) under such Arcturus Technology Patents nor obligations hereunder with respect to such Arcturus Technology Patents. For clarity, in the event that the Licensed Product is subsequently determined to be covered or otherwise infringe a Valid Claim of any excluded patent hereunder, then such infringement shall be deemed to be a material breach of this License Agreement by CureVac.

2.4Documents and Declarations. At CureVac’s reasonable request and cost and expense, Arcturus shall execute all documents, deliver declarations regarding the licenses granted hereunder, and Arcturus shall reasonably cooperate with CureVac to the extent such documents, declarations and/or cooperation are required to give effect to this License Agreement and/or for the recording or registration of the licenses granted hereunder at the

various patent offices in the Territory for the benefit of CureVac, its Affiliates or their Sublicensees.

2.5Diligence; Reporting. CureVac shall use Diligent Efforts to develop, manufacture and commercialize Licensed Products in the Field of Use in the Territory, and shall keep Arcturus reasonably informed as to the progress and results of its and its Affiliates’ and Sublicensees’ development, manufacture and commercialization of the Licensed Product. Without limiting the foregoing, CureVac shall provide Arcturus with a written report of the development, manufacture and commercialization of the Licensed Product within […***…] days after the end of each calendar year, and shall promptly respond to Arcturus reasonable questions or requests for additional information relating to such activities.

2.6Compliance. CureVac shall at all times comply with all applicable Laws (including anti-bribery laws) in the development, manufacture and commercialization of the Licensed Product and the performance of its other obligations under this License Agreement, and shall not use any employee or consultant who has been debarred by any Regulatory Authority or, to CureVac’s knowledge, is the subject of debarment proceedings by a regulatory authority.

2.7Updates. Arcturus shall inform CureVac within […***…] Business Days of intellectual property matters affecting the Arcturus Technology Patents and the Arcturus Know-How of which it becomes aware that would reasonably be considered to negatively impact the rights of CureVac pursuant to this Agreement.

2.8Material. CureVac shall have the right to retain Material provided by Arcturus under the Development and Option Agreement, to the extent such Material is necessary or useful for the exercise of a CureVac's rights or obligations under this License Agreement. Following the License Agreement Effective Date, only the provisions of this License Agreement, but not of the Development and Option Agreement, shall apply in relation to such Material.

3.1Reserved Rights. No licenses or other rights are granted by Arcturus hereunder to use any trademark, trade name, trade dress or service mark owned or otherwise Controlled by Arcturus or any of its Affiliates. All licenses and other rights are or shall be granted only as expressly provided in this License Agreement, and no other licenses or other rights is or shall be created or granted by either Party hereunder by implication, estoppel or otherwise. CureVac shall not, and shall not permit any of its Affiliates or Sublicensees to, practice or use any Arcturus Technology outside of the scope of the license granted to it under Section 2.1 or in contravention of Section 3.1. Arcturus retains the exclusive right to practice, license and otherwise exploit the Arcturus Technology outside the scope of the licenses granted to CureVac under Section 2.1 and in an event to practice any rights that are not exclusive pursuant to Section 2.1.

Existing Licensing Restriction with respect to the Target shall not be deemed a conflict hereunder. In addition, Arcturus shall use Diligent Efforts to undertake that any licenses obtained from Third Parties will be sublicensable to CureVac, to the extent required or useful for the Licensed Product, provided that CureVac shall be responsible for an allocable portion of the payment and obligations that may be required in order to obtain rights with respect to the Licensed Product pursuant to such Third Party agreement.

4.1Milestone Payments. CureVac will make milestone payments (each, a "Milestone Payment") to Arcturus upon the first occurrence of each of the milestone events (each, a "Milestone Event") by Licensed Product as set forth below in this Section 4.1. CureVac will notify Arcturus of the achievement of each Milestone Event (whether achieved by CureVac, its Affiliates or Sublicensees) within (i) […***…] Business Days of such achievement, if the Milestone Event is achieved by CureVac or its Affiliates, or (ii) […***…] Business Days of the receipt by CureVac of a notification about the achievement, if the Milestone Event is achieved by a Sublicensee.

Each Milestone Payment will be non-refundable, non-creditable and payable to Arcturus by CureVac within […***…] days of delivery of an invoice from Arcturus following notification from CureVac pursuant to the preceding paragraph, provided that if no such notification is timely provided by CureVac, the Milestone Payment shall be deemed payable […***…] days after (A) the achievement of such Milestone Event, if the Milestone Event is achieved by CureVac or its Affiliates, or (B) after the receipt by CureVac of the notification from CureVac pursuant to Section 4.1(ii). For clarity, the term “non-refundable” is not intended to limit either Party’s rights to pursue damages arising from a breach of this Agreement.

If one or more of the Milestone Events set forth below are not achieved or not required for any reason, the payment for such skipped Milestone Event will be due at the same time as the payment for the next achieved Milestone Event. For clarity: […***…].

For clarity, to the extent that a Licensed Product is initiated against a Rare Disease Target and later expanded to a non-Rare Disease Target, then any and all Milestone Payments not previously made shall be due and payable upon the achievement of the next non-Rare Disease Milestone (e.g., […***…]).

4.2Sublicensing Revenues.If within twenty-four (24) months after the License Agreement Effective Date CureVac grants a sublicense to a Third Party under this License Agreement for the development and commercialization of Licensed Products, then CureVac will pay to Arcturus […***…] of all Sublicense Income actually received by CureVac, to the extent the Sublicense Income exceeds the Option Exercise Fee paid by CureVac under the Development and Option Agreement to exercise the Option for this License Agreement and the Milestone Payments paid by CureVac under this License Agreement. The payments will be made within […***…] days after receipt by CureVac from the Third Party. For purposes of clarity, if CureVac grants a sublicense to Third Parties later than […***…] months after the License Agreement Effective Date, CureVac will not owe any Sublicensing Income to Arcturus.

as well as of any net sales milestones (without offset for any reductions pursuant to Section 4.3(b)) for such Licensed Product received from the Sublicensee.

(b)Third Party Payments and Royalty Reductions. If CureVac or its Affiliate or Sublicensee, in its reasonable judgment, considers it necessary or useful to obtain a license from any Third Party under any LMD Technology that Covers a Licensed Product in order to develop, manufacture or commercialize such Licensed Product, the amount of CureVac’s royalty obligations under Sections 4.3(a) will be reduced by […***…] of the amount of the upfront, milestone and royalty payments made to such Third Party on account of the development, manufacture or commercialization of such Licensed Product ("Royalty Reductions"), provided, however, that any Royalty Reduction shall not result in less than the minimum royalty due to Arcturus under Section (c) below.

(c)Minimum Royalty. In no event will the Royalty payable by CureVac to Arcturus for any Licensed Product be less than (i) […***…] if the reduction in subsection (e) does not apply; or (ii) […***…] if the reduction in subsection (e) also applies.

(d)Term. The royalty term ("Royalty Term") shall expire on a country-by-country and Licensed Product-by-Licensed Product basis, on the last to occur of (i) expiration of the last to expire Valid Claim in the Arcturus Technology that, but for the license described herein from Arcturus to CureVac for the applicable Licensed Product, is infringed by the making, using or sale of such Licensed Product, (ii) expiration of any period of data exclusivity, market exclusivity or supplemental protection certificates covering the Licensed Product in such country; and (iii) […***…] years after First Commercial Sale of Licensed Product in such country. For the avoidance of doubt, upon exhaustion of the obligation to pay Royalties to Arcturus as set forth above the continued use of Arcturus Know-How comprised in the Arcturus Technology for the development, manufacture and/or sale of the Licensed Product shall not, in and of itself, obligate CureVac to pay further royalties to Arcturus. Thereafter, CureVac's license under Section 2.1 will become irrevocable, perpetual, fully paid-up and royalty-free on a country-by-country and Licensed Product-by-Licensed Product basis.

(e)Know-How Royalty. On a country-by-country, and a Licensed -Product-by-Licensed Product basis, in the event that during the Royalty Term a Licensed Product is not covered by a Valid Claim, the royalty otherwise payable for such Licensed Product, after the Royalty Reductions above, will be reduced by […***…].

(a)Manner of Payment. All payments to be made by CureVac hereunder will be made in U.S. dollars by wire transfer to such bank account as Arcturus may designate.

year to which each shall pertain, such books and records of accounting (including those of CureVac’s Affiliates and Sublicensees) shall be kept at each of their principal places of business and shall be open for inspection at reasonable times and upon reasonable notice by an independent certified accountant selected by Arcturus, and which is reasonably acceptable to CureVac, for the sole purpose of inspecting the Net Sales calculations and supporting details to the extent reasonably necessary and resulting royalties and other amounts due to Arcturus under this License Agreement. In no event shall such inspections be conducted hereunder more frequently than once every […***…] months. Such accountant must have executed and delivered to CureVac and its Affiliates, a confidentiality agreement as reasonably requested by CureVac, which shall include provisions limiting such accountant’s disclosure to Arcturus to only the results and basis for such results of such inspection. The results of such inspection, if any, shall be binding on both Parties. Any underpayments plus interest from the original due date shall be paid by CureVac within […***…] days of notification of the results of such inspection. Any overpayments shall be fully creditable against amounts payable in subsequent payment periods. Arcturus shall pay for such inspections, except that in the event there is any upward adjustment in aggregate royalties and other amounts payable for any calendar year shown by such inspection of more than […***…] of the amount paid, CureVac shall reimburse Arcturus for any reasonable out-of-pocket costs of such accountant.

(c)Reports and Royalty Payments. For as long as royalties are due under Section 4.3, CureVac shall furnish to Arcturus written reports.

(i)Reports shall be provided within […***…] days of (1) the end of the Calendar Quarter if Net Sales are generated by CureVac and its Affiliates, and (2) the receipt of corresponding information (which may be estimated) from Sublicensees but in any event within […***…] days of the end of the Calendar Quarter with respect to Net Sales generated by such Sublicensees.

(ii)Royalty payments for each Calendar Quarter shall be due within […***…] Business Days of delivery of an invoice from Arcturus following submission of a royalty report from CureVac, but only subject to the prior receipt by CureVac of the corresponding royalty payment from the Sublicensee, if applicable; however such royalty payments due to Arcturus shall not be reduced by deductions which exceed those covered by the Net Sales definition according to Section 1.43.

(iii)The report shall include, at a minimum, the following information for the applicable Calendar Quarter for each Licensed Product if Net Sales are generated by CureVac and its Affiliates: (i) the gross sales by country reasonably required for the calculation of royalty payments due according to this Agreement, (ii) the calculation in reasonable detail of the Net Sales from such gross sales amounts, including the deductions pursuant to the definition of Net Sales and the amounts of any credits or reductions permitted by Section 4.2; and (iii) the computations for any Arcturus currency conversions pursuant to subsection (d) below.

(iv)CureVac will require each Sublicensee to share with Arcturus the information listed in the foregoing clauses as it relates to Net

Sales made by such Sublicensee, and to the extent practicable, will include such Sublicensee information in such report; provided that the level of detail with respect to the items subject to report pursuant to Section 4.4(c)(iii) shall be limited to the information that CureVac actually receives from any such Sublicensee. All such reports shall be considered the Confidential Information of CureVac, subject to Section 4.4(b).

(d)Currency Exchange. With respect to Net Sales invoiced in U.S. dollars, the Net Sales and the amounts due to Arcturus hereunder will be expressed in U.S. dollars. With respect to Net Sales invoiced in a currency other than U.S. dollars, payments will be calculated based on the average of the closing exchange rates reported by the Wall Street Journal (http://quotes.wsj.com/fx/EURUSD), or such other source as the Parties may agree in writing, of the applicable reporting period for the payment due.

(e)Taxes. CureVac may withhold from payments due to Arcturus amounts for payment of any withholding tax that is required by Law to be paid to any taxing authority with respect to such payments. CureVac will provide Arcturus all relevant documents and correspondence, and will also provide to Arcturus any other cooperation or assistance on a reasonable basis as may be necessary to enable Arcturus to claim exemption from such withholding taxes and to receive a refund of such withholding tax or claim a foreign tax credit. CureVac will give proper evidence from time to time as to the payment of any such tax. The Parties will cooperate with each other in seeking deductions under any double taxation or other similar treaty or agreement from time to time in force. CureVac shall use Diligent Efforts to minimize withholding taxes. In the event that any tax deduction or withholding obligation arises or increases as a direct result of any reincorporation, redomiciliation, change in source of payments under this Agreement or other similar corporate structuring actions undertaken by CureVac from and after the License Agreement Effective Date, then CureVac shall increase the payment (in respect of which such deduction or withholding of tax is required to be made) to ensure that Arcturus receives an amount equal to the amount that it would have received had no such action occurred. Apart from any such permitted withholding and those deductions expressly included in the definition of Net Sales, the amounts payable by CureVac to Arcturus hereunder will not be reduced on account of any taxes, charges, duties or other levies. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of the Parties under this License Agreement.

(f)Blocked Payments. In the event that, by reason of applicable law in any country, it becomes impossible or illegal for CureVac or its Affiliates or Sublicensees to transfer, or have transferred on its behalf, payments owed to Arcturus hereunder, CureVac will promptly notify Arcturus of the conditions preventing such transfer and such payments will be deposited in local currency in the relevant country to the credit of Arcturus in a recognized banking institution proposed by Arcturus and reasonably acceptable to CureVac or, if none is proposed by Arcturus within a period of […***…] days, in a recognized banking institution selected by CureVac or its Affiliate or Sublicensee, as the case may be, and identified in a written notice given to Arcturus.

(g)Interest Due. If any payment due to Arcturus under this License Agreement is overdue (and is not subject to a good faith dispute), then CureVac will

pay interest thereon (before and after any judgment) at an annual rate of the lesser of […***…] above the prime rate as reported in The Wall Street Journal, Eastern Edition, and the maximum rate permitted by applicable Law, such interest to run from the date upon which payment of such sum became due until payment thereof in full together with such interest.

(h)Mutual Convenience of the Parties. The royalty and other payment obligations set forth hereunder have been agreed to by the Parties for the purpose of reflecting and advancing their mutual convenience, including the ease of calculating and paying royalties and other amounts to Arcturus.

5.1Solely-Owned IP. As between the Parties and subject to Section 5.3, each Party will own and retain all right, title and interest in and to any and all Know-How and Patents arising therefrom that are discovered, created, conceived, developed or reduced to practice under or in connection with this License Agreement (the “Inventions”) solely by or on behalf of such Party. Subject to the licenses hereunder and the other terms and conditions of this License Agreement or any other agreement between the Parties, each Party will be solely responsible for the prosecution and maintenance, and the enforcement and defense, of its solely-owned Patents.

5.2Inventorship. Inventorship of all Inventions shall be determined in accordance with applicable laws. Each Party will ensure that each employee, consultant and subcontractor conducting any activities under this License Agreement on behalf of such Party will be subject to written agreements to assign to such Party all of its right, title and interest in and to the Inventions so that such Party can comply with its obligations with respect to the ownership allocation of the Inventions as set forth below. In addition, each Party shall be solely responsible for payments that may be required to any of such Party’s employees or consultants and subcontractors in connection with or with respect to such agreements, including moral rights payments.

5.3Ownership. Notwithstanding inventorship in the first instance pursuant to Section 5.2, ownership of all Inventions, as between the Parties, will be assigned by the Parties as follows: (a) Arcturus will solely own all Inventions that are improvements solely to the LMD Technology (“LMD Inventions”), and (b) CureVac will solely own all Inventions that are improvements solely to the mRNA Technology (“mRNA Inventions”). Specifically, CureVac hereby assigns to Arcturus all of its right, title and interest in and to any and all LMD Inventions, and agrees to take such actions reasonably requested by Arcturus to evidence such assignment. Arcturus hereby assigns to CureVac all of its right, title and interest in and to any and all mRNA Inventions, and agrees to take such actions reasonably requested by CureVac to evidence such assignment. For clarity, the assignment provisions with respect to mRNA Inventions are restricted solely to improvements to the mRNA Technology.

(a)As between the Parties and subject to Section 6.2 below, Arcturus (or its Third Party licensor, if any) will have the sole right, at its sole costs, to prosecute and maintain Arcturus Technology Patents, other than the Joint Interest Patents.

(b)In relation to any Arcturus Technology Patents that specifically claim the Licensed Product, prior to filing, Arcturus will provide CureVac with copies of all specific claims relevant to the Licensed Product in such applications for all such Arcturus Technology Patents, and all other material submissions and correspondence relating to such claims with any patent authorities regarding such Arcturus Technology Patents, in sufficient time (not to be less than […***…] days) to allow for review and comment by CureVac. In addition, Arcturus will provide CureVac and its counsel with an opportunity to consult with Arcturus and its counsel regarding prosecution and maintenance of any such Arcturus Technology Patents, and Arcturus will not unreasonably refuse to address all reasonable comments timely made by or on behalf of CureVac.

(c)As between the Parties, CureVac will have the first right to prosecute and maintain any and all Joint Interest Patents and the Parties will share equally all costs incurred by CureVac in connection with such efforts. Prior to filing, CureVac will provide Arcturus with copies of all applications for such Joint Interest Patents, and all other material submissions and correspondence with any patent authorities regarding such Joint Interest Patents, in sufficient time (not to be less than […***…] days) to allow for review and comment by Arcturus. In addition, CureVac will provide Arcturus and its counsel with an opportunity to consult with CureVac and its counsel regarding prosecution and maintenance of any such Joint Interest Patents, and CureVac will consider in good faith all reasonable comments timely made by or on behalf of Arcturus.

(d)In the event that CureVac or its Affiliates grants a sublicense pursuant to Section 2.2, as between CureVac and any such Sublicensee,

(a)If Arcturus elects not to pay its share of the Patent Costs associated with prosecution or maintenance of any Joint Interest Patents, then it shall assign its co-ownership share in such Patents to CureVac and the respective Patent shall no longer be considered a Joint Interest Patent.

(b)By CureVac. If CureVac elects not (i) to file, prosecute or maintain any Joint Interest Patents for which it is responsible under Section 6.1 in any particular country before the applicable filing deadline or continue such activities once filed in a particular country, or (ii) to pay its share of the Patent Costs associated with prosecution or maintenance of any Joint Interest Patents then in each such case CureVac will so notify Arcturus, promptly in writing and in good time to enable Arcturus to meet any deadlines by which an action must be taken to preserve such Joint Interest Patent in such country at Arcturus' expense, if Arcturus so requests. Upon receipt of each such notice by CureVac, Arcturus will have the right, but not the obligation, to notify CureVac in writing on a timely basis that CureVac should transfer the prosecution or maintenance of such Joint Interest Patent to Arcturus and at Arcturus' sole expense. Arcturus is entitled to discontinue the payment of Patent Costs for any Joint Interest Patents at any time, provided that it will so notify CureVac in writing in time for such discontinuance. In the event that Arcturus assumes the prosecution and maintenance of any such Joint Interest Patent, then CureVac would make available to Arcturus all documentation and correspondence with respect to such Joint Interest Patent, such Joint Interest Patent shall no longer be licensed under this Agreement with respect to the Licensed Product.

6.3Cooperation. Each Party will reasonably cooperate with the other Party in those activities involving the Arcturus Technology Patents and Joint Interest Patents set forth in Sections 6.1 and 6.2. Such cooperation includes promptly executing all documents, or requiring inventors, subcontractors, employees and consultants and agents of CureVac and Arcturus and their respective Affiliates and Sublicensees to execute all documents, as reasonable and appropriate so as to enable such activities in respect of any such Arcturus Technology Patents in any country.

7.1Notice. To the extent not in breach of an obligation of confidentiality, each Party will promptly notify, in writing, the other Party upon learning of any actual or suspected infringement of any Arcturus Technology Patents by a Third Party, or of any claim of invalidity, unenforceability, or non-infringement of any Arcturus Technology Patents, and will, along with such notice, supply the other Party with any evidence in its possession pertaining thereto.

(1)Arcturus and its Third Party licensor or licensee (solely to the extent of any existing back-up enforcement rights), at its cost, will have the first right, but not the obligation, to seek to abate any infringement of the Arcturus Technology Patents (other than those in subsection (2)) by a Third Party, or to file suit against any such Third Party for such infringement, and

Technology Patents that, on the date of first notice of such infringement, specifically claim the Licensed Product but are not necessary or useful for the research, development, manufacturing and commercialization of any product comprising Arcturus Technology that is exclusively licensed or optioned to a Third Party or is in Late Stage Development or being commercialized by Arcturus or its Affiliates.

(b)If the Party first responsible for such enforcement elects not to take action or to bring suit to prosecute such infringement or to continue such action or suit, it shall notify the other Party of such election within […***…] days after become aware of or receipt of the notice of the infringement or after the election to stop any such action or suit. If after the expiration of the […***…] days period (or, if earlier, the date upon which the responsible Party provides written notice that it does not plan to bring such action) the responsible Party has neither obtained a discontinuance of infringement nor filed suit against any such Third Party infringer of such Patent, then

(1)Arcturus and its Third Party licensor or licensee (solely to the extent of any existing back-up defense rights) will have the first right, but not the obligation, at its sole costs, to defend against a declaratory judgment action or other action challenging any Arcturus Technology Patents, other than: (i) Joint Interest Patents; and (ii) any other Arcturus Technology Patents that, on the date of first notice of such action, specifically claim the Licensed Product but are not necessary or useful for the research, development, manufacturing and commercialization of any product comprising Arcturus Technology that is exclusively licensed or optioned to a Third Party or is in Late Stage Development or being commercialized by Arcturus or its Affiliates, and

(2)CureVac shall have the first right, but not the obligation, at its sole costs, to defend against a declaratory judgment action or other action challenging Joint Interest Patents as well as such other Arcturus Technology Patents that specifically claim the Licensed Product.

(ii)

If the Party first responsible for such defense does not take steps to defend within a commercially reasonably time, or elects not to continue any such defense (in which case it will promptly provide notice thereof to the other Party), then (i) in the case of an election by Arcturus and its Third Party licensor or licensee (solely to the extent of any existing back-up defense rights) not to defend an Arcturus Technology Patent specifically claiming the Licensed Product, CureVac shall have the right, but not the obligation, to defend any Arcturus Technology Patents that cover Licensed Product and no other product licensed or optioned by Arcturus to a Third Party or commercialized by Arcturus, provided that CureVac shall bear all the expenses of such suit and (ii) in the case of a CureVac election not to defend the Joint Interest Patents, Arcturus shall have the right, but not the obligation, to take action or bring suit to defend such Patents, provided that Arcturus shall bear all the expenses of such suit. Notwithstanding the foregoing, in the event that CureVac elects not to prosecute an infringement of a Joint Interest Patent, then CureVac shall, at its discretion, either (i) assign such Joint Interest Patent to Arcturus – on a country-by-country basis -, which shall become an Arcturus Technology Patent and no longer subject to license pursuant to this License Agreement or (ii) join Arcturus in such suit to the extent legally required.

(d)Notwithstanding the foregoing, any response to a Third Party infringer's counterclaim of invalidity or unenforceability of any Arcturus Technology Patents shall be controlled by the Party who controls the relevant enforcement proceeding pursuant to Section 7.2 (a) unless otherwise mutually agreed by the Parties.

(e)In the event that CureVac or its Affiliates grants a sublicense pursuant to Section 2.2, as between CureVac and any such Sublicensee,

(f)Withdrawal, Cooperation and Participation. With respect to any infringement or defensive action identified above in this Section 7.2 which may be controlled by either CureVac or Arcturus:

(g)Settlement. Neither Party will settle or consent to an adverse judgment in any action described in this Section 7.2 and controlled by such Party, including any judgment which affects the scope, validity or enforcement of any Arcturus Technology Patents involved therewith, without the prior written consent of the other Party (such consent not to be unreasonably withheld, delayed or conditioned).

(h)Damages. Unless otherwise agreed by the Parties, all monies recovered upon the final judgment or settlement of any action which may be controlled by either CureVac or Arcturus and described in Section 7.2(a) or 7.2(c) in each case will be used first to reimburse the controlling Party, and thereafter the non-controlling Party, for each of their out-of-pocket costs and expenses relating to the action, with the balance of any such recovery to be divided as follows:

(i)Patent Marking. CureVac shall mark all Licensed Product if and to the extent required by the applicable patent marking laws, and shall require all of its Affiliates and sublicensees to do the same.

(f)Infringement. Neither Arcturus nor any of its Affiliates has received any written notice of any claim, nor does Arcturus or its Affiliates have any knowledge of any claim, that any Patent, Know-How or other intellectual property owned or controlled by a Third Party would be infringed or misappropriated by the practice of any Arcturus LMD Technology in connection with the production, use, research, development, manufacture or commercialization of any Licensed Product.

(g)Third Party Infringement. To Arcturus’ knowledge, no Third Party is infringing or has infringed any Patent within the Arcturus LMD Technology or is misappropriating or has misappropriated any Know-how within the Arcturus LMD Technology, in each case relating to the Target.

damages, provided that this Section 9.4 will not apply to breaches of Article 8 or the Parties’ indemnification rights or obligations under Section 9.6, or in the event of willful misconduct.

9.5Performance by Others. The Parties recognize that each Party may perform some or all of its obligations under this License Agreement through Affiliates, subcontractors or - in the event of CureVac - Sublicensees, provided, however, that each Party will remain fully responsible and liable for the performance by its Affiliates, subcontractors and Sublicensees, and will cause its Affiliates, subcontractors and Sublicensees to comply with the provisions of this License Agreement in connection therewith.

(a)Indemnification by CureVac. CureVac will indemnify Arcturus, its Affiliates and their respective directors, officers, employees, Third Party licensors and agents, and their respective successors, heirs and assigns (collectively, "Arcturus Indemnitees"), and defend and hold each of them harmless, from and against any and all losses, damages, liabilities, costs and expenses (including reasonable attorneys’ fees and expenses) (collectively, "Losses") in connection with any and all suits, investigations, claims or demands of Third Parties (collectively, "Third Party Claims") against the Arcturus Indemnitees to the extent arising from or occurring as a result of: (i) the breach by CureVac of any representation or warranty of this License Agreement; (ii) any gross negligence or willful misconduct on the part of any CureVac Indemnitee; or (iii) the development, manufacture or commercialization by or on behalf of CureVac or any of its Affiliates or Sublicensees of Licensed Product other than if related to an LMD component thereof specifically provided by Arcturus, except in each case (i)-(iii) to the extent arising from or occurring as a result of the gross negligence or willful misconduct on the part of an Arcturus Indemnitee or Arcturus’ breach of this License Agreement.

(b)Indemnification by Arcturus. Arcturus will indemnify CureVac, its Affiliates and their respective directors, officers, employees and agents, and their respective successors, heirs and assigns (collectively, "CureVac Indemnitees"), and defend and hold each of them harmless, from and against any and all Losses in connection with any and all Third Party Claims against CureVac Indemnitees to the extent arising from or occurring as a result of: (i) the breach by Arcturus of any representation or warranty of this License Agreement; or (ii) any gross negligence or willful misconduct on the part of any Arcturus Indemnitee, except in each case (i) and (ii) to the extent arising from or occurring as a result of the gross negligence or willful misconduct on the part of a CureVac Indemnitee or CureVac’s breach of this License Agreement.

(c)Notice of Claim. All indemnification claims provided for in Sections 9.6(a) and 9.6(b) will be made solely by such Party to this License Agreement (the "Indemnified Party"). The Indemnified Party will promptly notify the indemnifying Party (an "Indemnification Claim Notice") of any Losses or the discovery of any fact upon which the Indemnified Party intends to base a request for indemnification under Section 9.6(a) and 9.6(b), but in no event will the indemnifying Party be liable for any Losses 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.

(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 thirty (30) 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 such counsel and 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 as soon as possible 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. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless the Indemnified Party from and against the Third Party Claim, the Indemnified Party will reimburse the indemnifying Party for any and all costs and expenses (including reasonable attorneys’ fees and costs of suit) and any Third Party Claims incurred by the indemnifying Party in its defense of the Third Party Claim.

(ii)Right to Participate in Defense. Without limiting Section 9.6(d)(i), any Indemnified Party will be entitled to participate in, but not control, the defense of such Third Party Claim and to engage counsel of its choice for such purpose; provided, however, that such engagement will be at the Indemnified Party’s own cost and expense unless (i) the indemnifying Party has failed to promptly assume the defense and engage counsel in accordance with Section 9.6(d)(i) (in which case the Indemnified Party will control the defense) or (ii) the interests of the Indemnified Party and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under applicable Law, ethical rules or equitable principles, in which case the indemnifying Party will assume one hundred percent (100%) of any such costs and expenses of counsel for the Indemnified Party.

(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 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 9.6(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. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will use Diligent Efforts to 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, at the indemnifying Party’s expense. Such cooperation will include access during normal business hours afforded to the indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making indemnified parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party 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 9.6(d), the 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.

9.7Insurance . Each Party will maintain at its sole cost and expense, an adequate liability insurance or self-insurance program (including product liability insurance) to protect

against potential liabilities and risk arising out of activities to be performed under this License Agreement, and any agreement related hereto and upon such terms (including coverages, deductible limits and self-insured retentions) as are customary in the respective industry of such Party for the activities to be conducted by such Party under this License Agreement. Subject to the preceding sentence, such liability insurance or self-insurance program will insure against all types of liability, including personal injury, physical injury or property damage arising out of the manufacture, sale, use, distribution or marketing of Licensed Product. The coverage limits set forth herein will not create any limitation on a Party’s liability to the other under this License Agreement.

(a)This License Agreement will commence as of the License Agreement Effective Date and, unless sooner terminated in accordance with the terms hereof or by mutual written consent, will continue on a Licensed Product-by-Licensed Product and a country-by-country basis, until there are no more payments owed to Arcturus in such country (the longest such period of time hereunder, the "Term"). Upon there being no more such payments hereunder in such country, the license contained in Section 2.1 will become irrevocable, perpetual and fully paid up and will remain in effect with respect to such Licensed Product in such country.

(b)If the Target to which this License Agreement relates is chosen by the Parties for co-development under the Co-Development Agreement, this License Agreement will automatically terminate upon the written agreement of the Parties to include such programs under the Co-Development Agreement, in accordance with Section 4.2(a) of the Co-Development Agreement.

Bankruptcy Code and any foreign counterparts thereto. Without limiting the Parties’ rights under Section 365(n) of the U.S. Bankruptcy Code, if a case under U.S. Bankruptcy Code is commenced by or against a Party, the other Party shall be entitled to a copy of any and all such intellectual property and all embodiments of such intellectual property, and the same, if not in the possession of such other Party, shall be promptly delivered to it (i) before this License Agreement is rejected by or on behalf of the bankrupt Party, within thirty (30) days after the other Party’s written request, unless the bankrupt Party, or its trustee or receiver, elects within thirty (30) days to continue to perform all of its obligations under this License Agreement, or (ii) after any rejection of this License Agreement by or on behalf of the bankrupt Party, if not previously delivered as provided under clause (i) above. All rights of the Parties under this Section 10.4 and under Section 365(n) of the U.S. Bankruptcy Code are in addition to and not in substitution of any and all other rights, powers, and remedies that each Party may have under this License Agreement, under the U.S. Bankruptcy Code, and any other applicable Laws.

(a)Upon termination (but not expiration pursuant to Section 10.1) of this License Agreement for any reason:

(i)Cessation of Rights. Except as expressly provided herein, including Sections 8.5, 10.5(a) and as necessary for CureVac to sell off existing inventory as permitted under Section 10.5(iii) below, all rights and licenses granted by Arcturus to CureVac under this License Agreement will terminate. CureVac shall wind down the development (including any clinical trials), manufacture and commercialization of the Licensed Product in compliance with all applicable Laws and at its own cost and expense.

(ii)Sell Off. Notwithstanding the termination of CureVac's licenses and other rights under this License Agreement, CureVac shall retain the right to distribute, sell or otherwise dispose of its existing inventory of the Licensed Products, in each case that is intended for distribution, sale or disposition in the Territory, for a period of not more than six (6) months following the date of the effective termination, as though this License Agreement had not been terminated, and such distribution, sale or other disposition shall not constitute infringement of the Patents or other intellectual property or proprietary rights of Arcturus or its Affiliates. CureVac's right to distribute, sell or otherwise dispose of its existing inventory of the Licensed Products pursuant to this Section 10.5(a)(ii) shall be subject to CureVac's continuing obligation to pay royalties with respect to the Net Sales.

(b)Upon termination pursuant to Section 10.1(b), Arcturus shall refund to CureVac the Option Exercise Fee (as defined in the Development and Option Agreement), the Milestone Payments already paid by CureVac and all other payments made by CureVac in relation to this License Agreement.

Sections 1, 4 (to the extent of any outstanding payments accrued as of the effective date of termination), 5, 8, 9.4, 9.6, 10.5, 10.6 and 11. Termination or expiration of this License 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 License Agreement nor prejudice either Party’s right to obtain performance of any obligation.

(a)Disputes. Disputes arising under or in connection with this License Agreement will be resolved pursuant to this Section 11.1; provided, however, that in the event a dispute cannot be resolved without an adjudication of the rights or obligations of a Third Party (other than any CureVac Indemnitees or Arcturus Indemnitees identified in Section 9.6), the dispute procedures set forth Sections 11.1(c) and 11.1(c) will be inapplicable as to such dispute.

(b)Dispute Escalation. In the event of a dispute between the Parties, the Parties will first attempt in good faith to resolve such dispute by negotiation and consultation between themselves. In the event that such dispute is not resolved on an informal basis within thirty (30) days, either Party may, by written notice to the other, have such dispute referred to each Party’s Chief Executive Officer or his or her designee (who will be a senior executive with the appropriate authority to determine the matter for such party), who will attempt in good faith to resolve such dispute by negotiation and consultation for a thirty (30) day period following receipt of such written notice

(c)Dispute Resolution. In the event the Chief Executive Officers of the Parties are not able to resolve such dispute as set forth above, the Parties agree to try to solve such dispute amicably by mediation.

The location of the arbitration proceedings will be New York City, New York, U.S.. The number of arbitrators will be three (3). The language of the arbitration proceeding will be English. The decision of the arbitrators shall be final and binding upon the Parties (absent manifest error on the part of the arbitrator(s)) and enforceable in any court of competent jurisdiction.

No Party will incur any debts or make any commitments for the other, except to the extent, if at all, specifically provided therein. There are no express or implied third party beneficiaries hereunder (except for CureVac Indemnitees and Arcturus Indemnitees for purposes of Section 9.6). For clarity, CureVac does not grant to Arcturus any rights or licenses under this License Agreement to any CureVac technology or intellectual property rights.

11.3Compliance with Law. Each Party will perform or cause to be performed any and all of its obligations or the exercise of any and all of its rights hereunder in good scientific manner and in compliance with all applicable Law.

11.6Headings. All headings in this License Agreement are for convenience only and will not affect the meaning of any provision hereof.

11.7Waiver of Rule of Construction. Each Party has had the opportunity to consult with counsel in connection with the review, drafting and negotiation of this License Agreement. Accordingly, the rule of construction that any ambiguity in this License Agreement will be construed against the drafting party will not apply.

11.8Interpretation. Whenever any provision of this License Agreement uses the term "including" (or "includes"), such term will be deemed to mean "including without limitation" (or "includes without limitations"). "Herein," "hereby," "hereunder," "hereof" and other equivalent words refer to this License Agreement as an entirety and not solely to the particular portion of this License Agreement in which any such word is used. All definitions set forth herein will be deemed applicable whether the words defined are used herein in the singular or the plural.

11.10Assignment. This License Agreement may not be assigned by either Party, nor may either Party delegate its obligations or otherwise transfer licenses or other rights created by this License Agreement, except as expressly permitted hereunder or otherwise without the prior written consent of the other Party, which consent will not be unreasonably withheld, delayed or conditioned; provided that either Party may assign this License Agreement without such consent to an Affiliate or to its successor in connection with sale of all or

substantially all of its assets or business or that portion of its business pertaining to the subject matter of this License Agreement (whether by merger, consolidation or otherwise).

11.12Amendment and Waiver. This License Agreement may 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.

11.13Severability. In the event that any provision of this License Agreement will, for any reason, be held to be invalid or unenforceable in any respect, such invalidity or unenforceability will not affect any other provision hereof, and the Parties will negotiate in good faith to modify the License Agreement to preserve (to the extent possible) their original intent.

11.14Entire Agreement. This License Agreement together with the Development and Option Agreement and any other license agreements entered into during the Term pursuant to the Development and Option Agreement are the sole agreement with respect to the subject matter hereof and supersedes all other agreements and understandings between the Parties with respect to same.

11.15Force Majeure.
