(d)Yearly Vaccine Credit. As of the date hereof, Novavax agrees to grant to Gavi five credits of $80,000,000, one for each of the five Calendar Years of the Deferred Payment Term (each such Calendar Year credit, a “Yearly Vaccine Credit”) (for a total of $400,000,000 in Yearly Vaccine Credits) to be applied against any Qualifying Sales during the applicable Calendar Year. Each Yearly Vaccine Credit, and Gavi’s right to apply such credit against any Qualifying Sales, will expire upon the expiration of the applicable Calendar Year for such Yearly Vaccine Credit, regardless of the amount of Yearly Vaccine Credit then remaining. For clarity, Novavax shall release (or shall cause any applicable selling Third Party Acquiror or their Affiliates to release) Gavi (or, at Gavi’s direction, UNICEF or PAHO) irrevocably from any obligation they may otherwise have to pay in cash for Qualifying Sales of Vaccine, up to the value of the Yearly Vaccine Credit remaining in the applicable Calendar Year after reductions have been applied in accordance with Section 4(f) (Reduction of Yearly Vaccine Credit), plus any remaining Additional Vaccine Credit as provided in Section 4(k) (Additional Vaccine Credit).

(e)Amendment of Procurement Terms. Novavax agrees that, upon the request of UNICEF or PAHO (as applicable), it shall agree (or, if applicable, shall cause any relevant Third Party Acquiror or Affiliate to agree) to such amendments or additions to the terms of any existing or future agreement (but excluding any agreed purchase order under any such agreement) to which UNICEF or PAHO is a counterparty for the procurement of Vaccine as may be necessary or reasonable to enable UNICEF or PAHO to obtain full benefit from the Yearly Vaccine Credit (including by extending UNICEF or PAHO’s deadline to pay Novavax (or applicable Third Party Acquiror or Affiliate) for Vaccine such that UNICEF or PAHO is not required to pay Novavax (or applicable Third Party Acquiror or Affiliate) prior to the time when Novavax would recognize a Qualifying Sale and Gavi would be entitled to the corresponding Yearly Vaccine Credit or Additional Vaccine Credit (as applicable) in accordance with this Agreement).

(f)Reduction of Yearly Vaccine Credit. Subject to Section 4(m) (Restoration of Credit), the total amount of the Yearly Vaccine Credit for an applicable Calendar Year will be reduced on a Dollar-for-Dollar basis for such Calendar Year upon the occurrence, and in the amount, of each of: (i) Novavax’s cash payment of each Deferred Payment in accordance with Section 4(h) (Deferred Payments); and (ii) Qualifying Sales evidenced by Gavi’s receipt of a Qualifying Sales Notice. The Yearly Vaccine Credit in any given Calendar Year shall not be reduced to an amount less than zero.

(g)No Purchase Obligation; No Sale Obligation. Neither Gavi, nor any Person entitled to benefit from the Yearly Vaccine Credit and Additional Vaccine Credit, is under any

obligation, at any time, to purchase any doses of Vaccines or to fund any purchase of Vaccines pursuant to this Agreement. Notwithstanding any provision to the contrary set forth in this Agreement, Gavi acknowledges and agrees that Novavax has the sole right to set the price per dose for Vaccines it offers to supply to UNICEF or PAHO. Nothing in this Agreement obliges Novavax, at any time, to sell doses to UNICEF or PAHO at any price below the price offered by Novavax in a tender offer to UNICEF or PAHO, as applicable.

(h)Deferred Payments. Prior to the expiration of the Deferred Payment Term, Novavax will pay Gavi an amount equal to $400,000,000 in immediately available funds, divided into equal annual amounts of $80,000,000 each Calendar Year of the Deferred Payment Term, payable in quarterly installments for each Calendar Quarter during the Deferred Payment Term in the amounts set forth in Schedule 4(h) (Deferred Payment Schedule) (each such payment, a “Deferred Payment”). No later than [***] after the end of each Calendar Quarter, Novavax will: (i) provide Gavi with a complete and accurate Qualifying Sales Notice for all Qualifying Sales in such Calendar Quarter; and (ii) subject to Section 4(i) (Deferred Payment Reductions), pay the Deferred Payment for such Calendar Quarter to Gavi in such amount as set forth in Schedule 4(h) (Deferred Payment Schedule).

(i)Deferred Payment Reductions. Notwithstanding Section 4(h) (Deferred Payments), the Deferred Payment amount that Novavax is obligated to pay Gavi with respect to a Calendar Quarter (as set forth in Schedule 4(h) (Deferred Payment Schedule)) will be reduced, subject to Section 4(l) (Disputed Qualifying Sales) and Section 4(m) (Restoration of Credit), on a Dollar-for-Dollar basis by: (i) the value of the Qualifying Sales made in such Calendar Quarter as evidenced by a Qualifying Sales Notice; and (ii) any Excess Qualifying Sales that are applied to reduce the amount of such Deferred Payment pursuant to Section 4(j) (Excess Qualifying Sales); provided that no Deferred Payment will be less than zero.

(j)Excess Qualifying Sales. If the amount of all Qualifying Sales in a Calendar Quarter, as evidenced by a Qualifying Sales Notice, exceeds the Deferred Payment amount for such Calendar Quarter (the amount of such excess, if any, being the “Excess Qualifying Sales”), then Novavax may carry forward such Excess Qualifying Sales and apply them on a Dollar-for-Dollar basis against any Deferred Payment due in the same Calendar Year as such Calendar Quarter. For the avoidance of doubt, any such Excess Qualifying Sales may not be applied against Deferred Payments in any Calendar Year other than the Calendar Year in which such Qualifying Sales occurred.

(k)Additional Vaccine Credit. As of the date hereof, Novavax agrees to grant to Gavi a credit of $225,000,000 (the “Additional Vaccine Credit”) to be applied against any Qualifying Sales in any Calendar Year after the Yearly Vaccine Credit for such Calendar Year has been fully applied against Qualifying Sales in such Calendar Year. The total amount of the Additional Vaccine Credit will be reduced on a Dollar-for-Dollar basis by the amount of any Qualifying Sales it is applied against, evidenced by Gavi’s receipt of a Qualifying Sales Notice. The Additional Vaccine Credit will expire upon the expiration of the Deferred Payment Term, regardless of the amount of the Additional Vaccine Credit then remaining, provided that if Novavax (or its Affiliate) agrees to deliver Vaccines to UNICEF or PAHO, or under any agreement with UNICEF or PAHO, in the last Calendar Year of the Deferred Payment Term, but such Vaccines are actually delivered after the expiration of the Deferred Payment Term, then the Additional Vaccine Credit may be credited against Qualifying Sales for such Vaccines.

(l)Disputed Qualifying Sales.

(i)No later than [***] after Gavi’s receipt of a Qualifying Sales Notice in respect of a Calendar Quarter where the value of any Qualifying Sales specified therein has been applied against the Yearly Vaccine Credit in accordance with Section 4(f)

(Reduction of Yearly Vaccine Credit) or Additional Vaccine Credit in accordance with Section 4(k) (Additional Vaccine Credit), or in reduction of a Deferred Payment in accordance with Section 4(i) (Deferred Payment Reductions), if Gavi reasonably believes, acting in good faith, that the true value of the Qualifying Sales in that Calendar Quarter is less than the value of the Qualifying Sales specified in the corresponding Qualifying Sales Notice (such alleged difference in value, the “Alleged Discrepancy”), then Gavi may provide written notice to Novavax of the Alleged Discrepancy, such notice specifying in [***] detail Gavi’s basis for asserting there is an Alleged Discrepancy (such notice a “Disputed Qualifying Sales Notice”).

(ii)Novavax shall have a period of [***] after receipt of the Disputed Qualifying Sales Notice to provide Gavi with a [***] response (such response a “Disputed Qualifying Sales Response”): (a) confirming that Novavax agrees that the true value of the Qualifying Sales in the Calendar Quarter do not match the value of the Qualifying Sales specified in the corresponding Qualifying Sales Notice (the amount of any agreed discrepancy being an “Agreed Discrepancy”); or (b) if Novavax, reasonably believes, acting in good faith, that there is not an Alleged Discrepancy or that the actual discrepancy is less than the Alleged Discrepancy asserted by Gavi in its Disputed Qualifying Sales Notice, providing Gavi with Novavax’s basis for that belief in reasonable detail.

(iii)If Novavax does not provide Gavi with a Disputed Qualifying Sales Response within [***] after receipt of a Disputed Qualifying Sales Notice, then the Disputed Qualifying Sales Notice shall be final and binding on the Parties for all purposes, and the full amount of the Alleged Discrepancy specified in the Disputed Qualifying Sales Notice shall be treated from that date as an Agreed Discrepancy for the purposes of this Agreement.

(iv)If Novavax provides Gavi with a Disputed Qualifying Sales Response within [***] after receipt of a Disputed Qualifying Sales Notice where Novavax disputes the existence of some or all of the Alleged Discrepancy, then the Parties shall negotiate in good faith, for a period of [***] after Gavi’s receipt of such Disputed Qualifying Sales Response, regarding the amount (if any) of such discrepancy. If the Parties reach agreement as to the amount (if any) of such discrepancy within such [***] period, then the amount agreed shall be treated from the date of such agreement as an Agreed Discrepancy for the purposes of this Agreement.

(v)If the Parties are unable to reach agreement within [***] after Gavi’s receipt of such Disputed Qualifying Sales Response, then either Party may by written notice to the other require that the dispute be referred to an Expert and the procedure set out in Schedule 4(l) (Expert Determination Procedure) shall apply. The discrepancy (if any) determined by the Expert in accordance with Schedule 4(l) (Expert Determination Procedure) shall be treated as an Agreed Discrepancy from the date of the Expert’s determination for the purposes of this Agreement. Notwithstanding any provision to the contrary set forth in this Agreement, a Party’s dispute as to the adequacy of the information contained within a purported Disputed Qualifying Sales Notice or purported Disputed Qualifying Sales Response will not prevent or delay the other Party from referring a dispute to an Expert in accordance with this Section 4(l)(v).

(vi)In the event that there is an Agreed Discrepancy, there shall immediately be a corresponding restoration to the Yearly Vaccine Credit for the Calendar Year in which Novavax recorded such Qualifying Sale or the Additional Vaccine Credit, as applicable, in accordance with Section 4(m) (Restoration of Credit).

(m)Restoration of Credit. If either: (i) Novavax and a Vaccine customer agree, or it is finally determined through the applicable dispute resolution procedure for such Vaccine customer, that Vaccine delivered in a Qualifying Sale and applied against the Yearly Vaccine Credit in accordance with Section 4(f) (Reduction of Yearly Vaccine Credit) or Additional Vaccine Credit in accordance with Section 4(k) (Additional Vaccine Credit) was properly rejected by such customer and as a result such customer requested and was entitled to a refund by Novavax (rather than Novavax providing replacement Vaccine) (the date of such agreement or final determination, the “Rejection Date”); or (ii) there is an Agreed Discrepancy pursuant to Section 4(l) (Disputed Qualifying Sales), then, the Yearly Vaccine Credit for the Calendar Year in which Novavax recorded such Qualifying Sale for such rejected Vaccine or Agreed Discrepancy, or the Additional Vaccine Credit, as applicable, will be restored in the amount of such rejected Qualifying Sale or Agreed Discrepancy (the “Restored Amount”). If such Restored Amount was used to reduce one or more Deferred Payments in accordance with Section 4(i) (Deferred Payment Reductions) and there were no other Qualifying Sales in such Calendar Year that could be used to reduce the amount of the cash Deferred Payment in accordance with Section 4(j) (Excess Qualifying Sales) (including because the Calendar Year in which the Qualifying Sale was made has ended), then Novavax will pay Gavi such Restored Amount in cash within [***] after the Rejection Date or date of an Agreed Discrepancy (as applicable) that gave rise to the Restored Amount. For clarity, if a Vaccine customer receives replacement Vaccine for rejected Vaccine at no charge, then the Yearly Vaccine Credit or Additional Vaccine Credit used to purchase such rejected Vaccine will not be restored.

(n)Vaccine Purchases. Gavi will: (i) if requested to do so by written notice (provided [***]) from Novavax, inform UNICEF and PAHO annually in writing of the existence of the Yearly Vaccine Credit and Additional Vaccine Credit; (ii) provide a copy of each such written notice to Novavax; and (iii) not [***] influence UNICEF or any AMC92 country, or their employees, officials, or other representatives to (A) dissuade them from purchasing Vaccines or (B) alter the decision to purchase or procure Vaccines from Novavax, or the timing of Qualifying Sales, in each case (A) and (B), in a manner intended to reduce the amount of reductions to cash Deferred Payments pursuant to Section 4(i) (Deferred Payment Reductions). For the avoidance of doubt, Gavi will not be taken to [***] influence any of the foregoing Person(s) by reason of its sharing, in the ordinary course of its activities, data with such Person(s) regarding the characteristics of Vaccine(s) or other vaccine product(s), (including, data concerning vaccine presentations, pricing, indicative wastage rates, manufacturers, cold chain volume or handling).

(o)Examples. For example, and without limitation, the below chart sets forth example scenarios of how Qualifying Sales are applied against Deferred Payments owed to Gavi and the outstanding balance of the Yearly Vaccine Credit and Additional Vaccine Credit, with each example assuming that: (i) no Qualifying Sales are subject to Section 4(l) (Disputed Qualifying Sales) or Section 4(m) (Restoration of Credit); and (ii) save whether otherwise indicated, Qualifying Sales are spread evenly over each Calendar Quarter of the Deferred Payment Term:

(p)Waiver. Notwithstanding any provisions to the contrary contained in the APA or in any other written agreement or other arrangement between the Parties, but without prejudice to the Parties’ rights and remedies in respect of any breach of any Settlement Document or upon the occurrence of any Event of Default, the Parties expressly acknowledge and agree that, as of the First Payment Date, save for the amounts owed by Novavax under this Agreement and the Security Agreement; (i) no other amounts are owed by Novavax or Gavi under the APA or any other written agreement or other arrangement between the Parties; (ii) Novavax is not obligated to pay, and Gavi is not entitled to receive, any further amounts under the APA or any other written agreement or other arrangement between the Parties; (iii) Gavi is not obligated to pay, and Novavax is not entitled to receive, any amounts under the APA, this Agreement or any other written agreement or other arrangement between the Parties; and (iv) the Parties expressly waive any right to receive any other or additional payment under the APA or any other written agreement or other arrangement between the Parties.

(q)Prepayment of Entire Remaining Payments. Novavax may pay the entire amount of the Remaining Payments in cash at any time in its sole discretion, and upon the date of Gavi’s receipt of such payment in full together with any other amounts accrued or outstanding under this Agreement; (a) all unpaid Deferred Payments will be paid in full and (b) all Yearly Vaccine Credits unapplied as of such date will expire. The Security Agreement, and therefore also the Security Interest, will be terminated and of no further force and effect upon the date of Gavi’s receipt of such pre-payment in full of the Remaining Payments (together with any other amounts accrued or outstanding under this

Agreement) in accordance with this Section 4(q) (Prepayment of Entire Remaining Payments). For the avoidance of doubt, Novavax’s pre-payment of the Remaining Payments as contemplated by this Section 4(q) (Prepayment of Entire Remaining Payments) will have no effect on the Additional Vaccine Credit, which may continue to be applied to Qualifying Sales during the Deferred Payment Term and, for the purposes of Section 4(k) (Additional Vaccine Credit), the requirement that the Yearly Vaccine Credit for a Calendar Year be fully applied before Qualifying Sales may be applied against the Additional Vaccine Credit shall be disregarded.

5.Interest.

(a)If Novavax fails to pay when due any Deferred Payment or Restored Amount payable under this Agreement (including where such amounts become due by virtue of acceleration in accordance with Section 7 (Acceleration)), Novavax shall pay interest on such overdue sum from the date when such payment became due until the date of actual payment (whether before or after any judgment or award) at a rate per annum of [***]. Such interest shall accrue [***] and shall be compounded [***].

(b)For the purposes of this Section 5 (Interest):

(i)where a Restored Amount arises from an Agreed Discrepancy that was caused by Novavax’s negligence, fraud or willful misconduct, the payment shall be treated as overdue from the date on which the reduction to the relevant Deferred Payment occurred in accordance with Section 4(i) (Deferred Payment Reductions); and

(ii)where a Restored Amount arises for any other reason, the payment of the Restored Amount shall be treated as overdue from the date that is [***] after the Rejection Date or date of the Agreed Discrepancy (as applicable) that gave rise to the Restored Amount, in accordance with Section 4(m) (Restoration of Credit).

6.Events of Default. Each of the following shall be an “Event of Default” under this Agreement, unless explicitly waived by Gavi (and, for the avoidance of doubt, references to “Novavax” and “Novavax AB” in this Section 6 shall also include their respective successors and assigns):

(a)Novavax does not pay, within [***] of the due date thereof, any Deferred Payment or Restored Amount payable to Gavi pursuant to this Agreement, provided that such [***] period shall be tolled with respect to the amount (if any) of a Deferred Payment that is the subject of a non-frivolous, non-vexatious dispute, during the pendency of any dispute resolution procedure initiated by Novavax for resolution of such dispute in accordance with Section 17(f) (Dispute Resolution);

(b)Novavax breaches the covenant set forth in Section 13(e)(i), provided that: (i) the breach is not capable of remedy; or (ii) Novavax fails to remedy the breach within [***] of Gavi giving notice to Novavax of the breach;

(d)Novavax or Novavax AB materially breaches an express provision of any of the Settlement Documents (other than a breach referred to in Sections 6(a), 6(b) or 6(c),

which shall give rise to an Event of Default in the circumstances set out in Sections 6(a), 6(b) or 6(c), respectively), which has or can reasonably be expected to have a material adverse effect on: (a) the validity, effectiveness, ranking or enforceability of the Security Interest; or (b) the Secured Accounts Receivable; or (c) the ability of Novavax to comply with its payment obligations under the Settlement Documents, provided that: (i) the material breach and corresponding effect on the Security Interest or Secured Accounts Receivable or payment obligations are not capable of remedy; or (ii) Novavax or Novavax AB (as applicable) fails to remedy the material breach and corresponding effect on the Security Interest or Secured Accounts Receivable or payment obligations within [thirty (30) days] of Gavi giving notice to Novavax of the breach;

(e)Novavax: (i) rescinds, or purports to rescind, or repudiates, or purports to repudiate, any of the Settlement Documents, or the Security Interest created or expressed to be created thereunder, or directly or indirectly itself or through any Affiliate (including Novavax AB); (ii) contests the validity or enforceability of any of the Settlement Documents, or the Security Interest created or expressed to be created thereunder; (iii) a proceeding is commenced by Novavax or any of its Affiliates (including Novavax AB) seeking to establish the invalidity or unenforceability of any of the Settlement Documents, or the Security Interest created or expressed to be created thereunder; or (iv) Novavax or one of its Affiliates (including Novavax AB) denies in writing that it has any liability or obligation purported to be created under any of the Settlement Documents;

(f)any of the Settlement Documents, the Security Interest or any of Novavax’s obligations created or expressed to be created thereunder, ceases to be legal, valid, binding, effective, or enforceable;

(g)one or more of the following occurs:

(i)[***]

(ii)[***]

provided that, in the case of (i) only:

(A) [***];

(B) [***]; and

(h)[***]

(i)a representation made by Novavax pursuant to Section 13(c)(ii), 13(c)(viii), 13(c)(ix), or 13(c)(xiv) of this Agreement is or proves to have been incorrect in any material respect when made or deemed to be made;

(j)[***]; or

(k)a Solvency-Related Event occurs in respect of Novavax during the Deferred Payment Term or at any time prior to [***] after receipt of the final Deferred Payment constituting the Settlement Amount or, if such final Deferred Payment is subject to an Alleged

Discrepancy that becomes an Agreed Discrepancy, receipt of any Restored Amount in respect of such Agreed Discrepancy.

7.Acceleration.

(a)Upon the occurrence of an Event of Default resulting from a Solvency-Related Event, the Remaining Payments, together with accrued interest pursuant to Section 5 (Interest), and all other amounts accrued or outstanding under this Agreement will be immediately due and payable.

(b)On and at any time after the occurrence of an Event of Default other than with respect to a Solvency-Related Event, Gavi may, by notice in writing to Novavax, declare that the Remaining Payments, together with accrued interest pursuant to Section 5 (Interest), and all other amounts accrued or outstanding under this Agreement be immediately due and payable, whereupon they shall become immediately due and payable.

(c)If any amounts become immediately due and payable pursuant this Section 7 (Acceleration), Gavi may exercise any or all of its right, remedies, powers or discretions under this Agreement or the Security Agreement.

8.Security Interest. Concurrently with the execution of this Agreement, Gavi and Novavax will enter into a Security Agreement in the form set forth in Exhibit C (Form of Security Agreement) (the “Security Agreement”) pursuant to which Novavax will grant Gavi a security interest in all its receivables from Serum (or its Affiliates) pursuant to the Serum License and Supply Agreement (which accounts receivable have been assigned by Novavax AB to Novavax) for the duration of the term of the Serum License and Supply Agreement in and to all accounts receivable due to Novavax, including the purchase price of Matrix-M adjuvant (or its bulk components) supplied thereunder and royalties paid with respect to the sale of Serum’s R21 malaria vaccine (the “Secured Accounts Receivable”) to secure Novavax’s obligations under this Agreement. The form of agreement between Novavax and Novavax AB providing for a confirmatory assignment of the Secured Accounts Receivable from Novavax AB to Novavax is set forth in Exhibit D (Form of Confirmatory Assignment of Accounts Receivable) (the “Confirmatory Assignment”), which Confirmatory Assignment has been executed by Novavax AB and Novavax prior to the Effective Date. For the avoidance of doubt, Gavi’s rights, powers, and remedies provided in this Agreement are in addition to, and not exclusive of, any rights, powers, or remedies set forth in the other Settlement Documents, and no exercise of any right, power, or remedy by Gavi hereunder shall be deemed a waiver of any right, power, or remedy under the other Settlement Documents.

9.Transfer of Serum License and Supply Agreement. A form of agreement between Novavax and Novavax AB providing for the present assignment and transfer to Novavax of Novavax AB’s obligations and rights (save for its rights in the Secured Accounts Receivable, which have been assigned by Novavax AB to Novavax as described in Section 8 (Security Interest)), and Novavax’s assumption of Novavax AB’s obligations under the Serum License and Supply Agreement, is set forth in Exhibit E (Form of Transfer Agreement) (the “Transfer Agreement”), which agreement has been executed by Novavax AB and Novavax, Inc. prior to the Effective Date.

10.Mutual Release of Claims.

(a)Release by Novavax.

The Novavax Releasors agree that they will: (i) forbear from exercising any rights or remedies against any Gavi Releasee in respect of any or all Actions and Liabilities in connection with the APA; and (ii) not commence any lawsuit or bring any legal or equitable action against any Gavi Releasee in respect of any Action or Liability in connection with the APA, in each case, except to the extent relating to a violation of applicable law by Gavi unless such violation is caused by the action or omission of a Novavax Releasor.

(b)Release by Gavi. Subject to Section 10(c) (Actions or Liabilities under the Settlement Agreement), but notwithstanding any provision to the contrary set forth in the APA, from and after the First Payment Date: Gavi, on behalf of itself and each of its Affiliates and each of their respective successors and assigns (collectively, the “Gavi Releasors”), do hereby now and forever release, remise, hold harmless and forever discharge Novavax, its Affiliates, its sublicensees and each of its, its Affiliates’, and its sublicensees’ respective sublicensees, officers, directors, employees, consultants, contractors and agents, and its and any and all of the foregoing Persons’ respective successors and assigns (collectively, the “Novavax Releasees”) of and from any and all Actions and Liabilities, whether known or unknown, suspected or unsuspected and that arose at any time on or prior to the First Payment Date, or that thereafter could arise based on any act, fact, transaction, matter, or cause that occurred on or prior to the First Payment Date arising from, under or otherwise in connection with the APA, in each case, other than for obligations arising under this Agreement or a violation of applicable law by Novavax unless such violation is caused by the action or omission of a Gavi Releasor. The Gavi Releasors agree that they will: (i) forbear from exercising any rights or remedies against any Novavax Releasee in respect of any or all Actions and Liabilities in connection with the APA; and (ii) not commence any lawsuit or bring any legal or equitable action against any Novavax Releasee in respect of any Action or Liability in connection with the APA, in each case, except to the extent relating to a violation of applicable law by Novavax unless such violation is caused by the action or omission of a Gavi Releasor.

(c)Actions or Liabilities under the Settlement Documents. Sections 10(a) (Release by Novavax) and 10(b) (Release by Gavi) shall not apply to any Actions or Liabilities arising from, under or otherwise in connection with the terms of any of the Settlement Documents, including any breach thereof by any Party.

(d)Third Party Beneficiaries. Except as expressly provided by this Section 10(d) (Third Party Beneficiaries), no Third Party shall have any rights under the Contracts (Rights of

Third Parties) Act of 1999 to enforce the terms of this Agreement. Notwithstanding the foregoing, each Gavi Releasee and each Novavax Releasee will be an express beneficiary of the rights and releases granted under this Section 10 (Mutual Release of Claims) subject to, and in accordance with, the Contracts (Rights of Third Parties) Act of 1999, and will be entitled to rely on the same as a defense to any Actions or Liabilities asserted against such Gavi Releasee or Novavax Releasee, as applicable, in contravention of the provisions of this Section 10 (Mutual Release of Claims), without regard to the fact that such Gavi Releasee or Novavax Releasee, as applicable, may not be a Party to this Agreement.

11.Dismissal of Arbitration. Within [***] after the First Payment Date, the Parties will instruct their respective counsel to prepare, execute, and submit a joint motion to dismiss with prejudice all claims and counterclaims and terminate the Arbitration, with each Party bearing its own fees and costs, including any cost the ICC already invoiced. The Parties will promptly proceed with any additional procedures needed to dismiss the Arbitration with prejudice, or any procedural equivalent available under the ICC Rules. The Parties will jointly request that the ICC allocate any additional arbitration costs equally between the Parties and reimburse all unused portions of the advances paid by each Party with respect to the Arbitration, in accordance with the ICC Rules. If the ICC declines to dismiss the Arbitration (or any claim therein) based on the joint motions to dismiss, the Parties and their counsel will cooperate to prepare, execute, and submit revised submissions, mutually acceptable to the Parties and the ICC, that most closely approximate a joint motion to dismiss with prejudice. For clarity, the Parties shall not be required to take any action under this Section 11 (Dismissal of Arbitration) if Novavax fails to pay Gavi the Initial Settlement Payment.

12.Termination. Notwithstanding any provision of this Agreement to the contrary, if the First Payment Date has not occurred within [***] of the Effective Date, Gavi shall be entitled to terminate this Agreement with immediate effect by giving notice in writing to Novavax. For the avoidance of doubt, and without prejudice to any accrued rights and remedies under this Agreement, in the event of termination in accordance with this Section 12, the First Payment Date will have not occurred and accordingly (but without limitation), the Parties shall remain entitled to pursue all Actions arising under or in connection with the APA in the Arbitration or otherwise.

Neither Party will be required to seek the permission of the other Party to repeat any information, nor express an opinion publicly (orally or in writing) in relation to such information, that has already been publicly disclosed by such Party or by the other Party, in accordance with this Section 14(d), provided that such information remains accurate as of such time.

(e)News Agencies. Notwithstanding any provision to the contrary set forth in this Agreement, either Party may provide an advance copy of a public disclosure authorized under Section 14(d) (Press Release) or otherwise agreed by the Parties to any news agency no more than [***] prior to the agreed disclosure date, provided that: (i) each such news agency agrees to binding terms to keep such disclosure strictly confidential until a Party issues such disclosure in accordance with this Agreement; and (ii) each Party informs the other Party in writing of the identity of any such news agency to which it intends to provide an advance copy at least [***] prior to any such disclosure taking place.

(f)Regulatory disclosure by Novavax. Notwithstanding any provision to the contrary set forth in this Agreement (including Sections 14(c)(vi) and 14(d) (Press Release)), Novavax shall make the first disclosure in connection with its entry into this Agreement that it is required to make by applicable law or the rules of a securities exchange on which its securities are listed no earlier than the First Payment Date. Novavax shall provide to Gavi a copy of such first disclosure no less than [***] prior to the date on which it makes such disclosure.

15.No termination for breach. No Party shall be entitled to terminate this Agreement on the grounds of a breach by another Party of Section 4(n) (Vaccine Purchases) or Section 14 (Confidentiality).

16.Limitation of liability. With the exception of losses that cannot be excluded or limited at law, neither Party shall be liable to the other or to any Third Party, whether in contract (including under any indemnity), in tort (including negligence), under any statute or otherwise under or in connection with this Agreement for or in respect of any: (i) loss of profit, sales, business, contracts or use of information; or (ii) indirect or consequential loss of whatever nature. However, nothing in this Section 16 (Limitation of liability) shall limit Novavax’s payment obligations under this Agreement.

17.Miscellaneous.

(a)No Admission of Liability. Except for the obligations expressly set forth in this Agreement, nothing in this Agreement will be construed to be an admission of liability by either Party to the other Party or to any Third Party.

(b)Intellectual Property. No rights or obligations in respect of either Party’s Intellectual Property Rights are granted, or are implied to be granted, to the other Party by this Agreement. In particular, as between the Parties, Novavax will be the sole owner of all Intellectual Property Rights generated during the development, manufacture and supply of Vaccine or otherwise related to Vaccine, and nothing in this Agreement will affect Novavax’s ownership of such rights.

(c)Severability. If any provision of this Agreement is declared illegal, invalid or unenforceable by a court of last resort or by any court or other governmental body from the decision of which an appeal is not taken within the time provided by law, then and in such event, this Agreement will be deemed to have been terminated only as to the portion thereof that relates to the provision declared illegal, invalid or unenforceable by that decision and only in the relevant jurisdiction, but this Agreement, in all other respects and all other jurisdictions, will remain in force; provided, however, that if the provision declared illegal, invalid or unenforceable is essential to the Agreement as a whole, then the Parties will negotiate in good faith to amend the terms hereof as nearly as practical to carry out the original intent of the Parties, and, failing such amendment, either Party may submit the matter for resolution pursuant to Section 17(f) (Dispute Resolution) of this Agreement.

(d)Further Assurance. The Parties agree to reasonably cooperate with each other in connection with any actions required to be taken as part of their respective obligations under this Agreement, and will: (i) furnish to each other such further information; (ii) execute and deliver to each other such other documents; and (iii) do such other acts and things (including working collaboratively to correct any clerical, typographical, or other similar errors in this Agreement); in each case ((i) through (iii)), all as the other Party may reasonably request for the purpose of carrying out the intent of this Agreement.

(e)Governing Law. This Agreement and all amendments, modifications, alterations, or supplements hereto, and the rights of the Parties hereunder, will be construed under and governed by the laws of [***], exclusive of its conflicts of laws principles. This Agreement has been prepared in the English language and the English language will control its interpretation. All consents, notices, reports, and other written documents to be delivered or provided by a Party under this Agreement will be in the English language, and in the event of any conflict between the provisions of any document and the English language translation thereof, the terms of the English language translation will control.

(f)Dispute Resolution. [***]

(g)No Avoidance of Settlement Amount. If payment of the Settlement Amount or any portion thereof (including the Initial Settlement Payment, a Deferred Payment, or a Restored Amount) should for any reason be declared to be void or voidable under any applicable law relating to creditors’ rights or otherwise, including provisions of the US Bankruptcy Code relating to fraudulent transfers, preferences or other voidable or recoverable payments of money or transfers of property (whether under the US Bankruptcy Code or any equivalent law of any other jurisdiction) (any of the foregoing, a “Voidable Transfer”), and if Gavi is required to repay or restore, in whole or in part, any such Voidable Transfer, or elects to do so upon the reasonable advice of its counsel, then the liability of Novavax for the amount thereof that Gavi is required or elects to repay or restore for such Voidable Transfer shall automatically be revived, reinstated and restored and shall exist as though such Voidable Transfer had never been made, and Gavi shall have a claim for such reinstated amounts plus the Remaining Payments under this Agreement, together with: (a) interest on any portion of the Remaining Payments that has accrued in accordance with Section 5 (Interest); and (b) interest on such reinstated

amounts, calculated in accordance with Section 5 (Interest) (as though, for the purposes of applying Section 5 (Interest), such reinstated amount were a Deferred Payment that became due and payable by Novavax on the date on which Gavi was required or elected to repay or restore such amount). Nothing herein shall be used as evidence that, or deemed to be an acknowledgement that, all or any portion of the Settlement Amount constitutes or may constitute a Voidable Transfer.

(h)Notices. Any notice required to be given under this Agreement will be in writing and will be mailed by internationally recognized express delivery service, or sent by email and confirmed by mailing, as follows (or to such other address as the Party to whom notice is to be given has provided to the other Party by way of written notice sent in accordance with this Section 17(h) (Notices)):

If to Gavi:

(i)Deemed receipt of notices. A notice sent in accordance with Section 17(h) (Notices) shall be effective upon receipt and shall be deemed to have been received: at the time of delivery, if delivered by express delivery service alone; or at the time of sending by e-mail, if sent by e-mail and express delivery service, provided that: (a) receipt shall not

occur if the sender receives an automated message that the e-mail has not been delivered to the recipient; and (b) a notice that is deemed by this Section 17(i) (Deemed receipt of notices) to be received after 5.00 p.m. on any day, or on a Saturday, Sunday or public holiday in the place of receipt, shall be deemed to be received at 9.00 a.m. on the next day that is not a Saturday, Sunday or public holiday in the place of receipt. For the purposes of this Section 17(i) (Deemed receipt of notices), all references to time are to local time in the place of receipt, and for the purposes of notices by e-mail, the place of receipt is the place in which the Party to whom the notice is sent has its postal address for the purpose of this Agreement.

(j)Assignment, transfer and novation.

(i) Subject to sub-paragraph (ii), neither Party may assign and transfer the benefit and burdens of the whole or any part of this Agreement without the other Party’s prior written consent.

(ii) A Party may assign the benefit of this Agreement to: (a) a Third Party successor or purchaser of all or substantially all of the assets or businesses to which this Agreement relates whether pursuant to a sale of assets, merger, or other transaction, in which case the assigning Party will provide prior written notice of such assignment to the other Party and need not obtain the other Party’s consent; or (a) an Affiliate of such Party, in which case the assigning Party will provide prior written notice of such assignment to the other Party and need not obtain the other Party’s consent;

provided that, in each case ((a) and (b)): (x) the assignee executes and delivers to the other Party a deed (in form and substance satisfactory to that other Party, acting reasonably) in which it agrees to assume all of the assigning Party’s obligations under this Agreement; and (y) the assigning Party remains fully liable for the performance of its obligations hereunder.

Any other assignment of this Agreement by a Party, (save as set out in sub-paragraph (ii)), or transfer or novation of this Agreement by a Party, requires the prior written consent of the other Party. Any purported assignment, transfer, or novation in violation of this Section 17(j) (Assignment, transfer and novation) will be null and void.

This Agreement will inure to the benefit of the permitted assigns of the Parties.
