For the avoidance of doubt, Novavax’s supply of Adjuvant for any reason other than for SLS’s Authorized Manufacturer to Manufacture Product to be supplied to Novavax under this Supply Agreement shall be governed by the terms and conditions of the applicable agreement in connection with which such Adjuvant is supplied by Novavax, including without limitation the Adjuvant price and related payment terms. SLS shall ensure that its Authorized Manufacturer (i) segregates the Adjuvant supplied hereunder from any other materials held by such Authorized Manufacturer, including without limitation any Adjuvant purchased from Novavax under any other agreements pursuant to which Novavax supplies Adjuvant to the Authorized Manufacturer or its Affiliates, and (ii) upon Novavax’s written request, promptly returns all or part of such Adjuvant to Novavax or its designated carrier without delay at SLS’s cost and expense.

Notwithstanding any other agreements, terms or documents between or among the Parties to the contrary, SLS shall, and shall ensure that its Authorized Manufacturer shall, use the Adjuvant supplied hereunder solely for the purpose of Manufacturing the Drug Product to be supplied to Novavax in accordance with this Supply Agreement and for no other purpose, including for the manufacture, development or commercialization of any products containing Adjuvant that are the subject of separate agreements.

(b) Starting April 15, 2024, SLS shall (or shall cause its Authorized Manufacturer to) provide Novavax with a [***] report containing (i) [***], and; (ii) [***].

(a) SLS shall (or shall cause its Authorized Manufacturer to) provide Novavax with a [***] report containing (i) [***], and (ii) [***].

(b) Prior to the beginning of each Seasonal Year during the Term, the Parties shall negotiate in good faith and agree upon a mutually acceptable, written Drug Substance safety stock plan for the upcoming Seasonal Year (each such plan, a “Safety Stock Plan” and the quantities of Drug Substance to be kept in safety stock at any given time pursuant to such Safety Stock Plan, the “Safety Stock”). SLS (either itself or through its Authorized Manufacturer) will maintain the Safety Stock for the sole benefit of Novavax and will use Safety Stock solely to Manufacture and supply Product to Novavax under this Supply Agreement. The Safety Stock shall be stored at a secure facility in compliance with GMP. SLS (either itself or through its Authorized Manufacturer) will at all times maintain the level of Safety Stock required under the then-current Safety Stock Plan by promptly replenishing the Drug Substance held as Safety Stock.

(a)The price to be paid by Novavax to SLS for the Manufacture and supply of Drug Substance that is delivered in accordance with Section 2.4 of this Supply Agreement is set forth in this Schedule 4.1.1 and shall be [***] (“DS Supply Price”), subject to adjustment from time to time as set forth in clause (e) below of this Schedule 4.1.1. At the time of initiation of the shipment of Drug Substance (or at such other time as may be agreed by the Parties in writing and evidenced in a Purchase Order), SLS shall issue an invoice to Novavax at the DS Supply Price for the quantities of Drug Substance being shipped, and Novavax will pay SLS [***] of the invoice amount before the shipment of such Drug Substance and balance [***] of the invoice amount within [***] from the delivery of the shipment of the Drug Substance. For the avoidance of doubt, the DS Supply Price only applies to Drug Substance delivered to Novavax or its designee in accordance with Section 2.4 of this Supply Agreement pursuant to Purchase Orders placed by Novavax, and does not apply with respect to (and Novavax shall not pay for any cost of Manufacturing) any Drug Substance that is utilized in the Manufacture of Drug Product by or on behalf of SLS under this Supply Agreement. SLS or its Authorized Manufacturer shall ship Drug Substance with [***]. The Authorized Manufacturer of SLS shall be responsible for the exportation clearance and process and act as Exporter of Record.

(b)The prices to be paid by Novavax to SLS for the Manufacture and supply of Drug Product delivered in accordance with Section 2.4 of this Supply Agreement shall be as set forth below in this clause (b), subject to adjustment from time to time as set forth in clause (e) below of this Schedule 4.1.1.

(i)The following supply prices (the “Risk Share Price”) shall be applicable to all Drug Product delivered in accordance with Section 2.4 of this Supply Agreement: [***].

(ii)The following supply prices (the “Full Supply Price”) shall be applicable only to Drug Product that is distributed to an End Customer: [***]. Notwithstanding the foregoing, if Drug Product is Manufactured by or on behalf of SLS or its Authorized Manufacturer utilizing Drug Substance manufactured and supplied by Novavax or its Affiliate or subcontractor, the Full Supply Price for each presentation of such Drug Product shall be: [***].

(iii)[***] for Drug Product Delivery to Novavax: SLS or its Authorized Manufacturer shall ship Drug Product with [***]. The Authorized Manufacturer of SLS shall be responsible for the exportation clearance and process and act as Exporter of Record.

(iv)At the time of initiation of Product Shipment of Drug Product (or at such other time as may be agreed by the Parties in writing and evidenced in a Purchase Order), SLS shall issue an invoice to Novavax which shall

specify (A) the Full Supply Price for the quantities of Drug Product to be shipped, (B) [***] of the partial payment/Risk Share Price for the quantities of Drug Product shipped which will be due within [***] from the date of invoice at the Risk Share Price, and (C) the remainder that will be due or credited in accordance with clause (c) below of this Schedule 4.1.1. Within [***] after receipt of such invoice, Novavax will pay SLS all undisputed amounts set forth in such invoice being the partial payment at the applicable Risk Share Price.

(c)Within [***] after the end of each [***] during the Term, Novavax will provide a written report to SLS reflecting: (i) the number of doses of Drug Product distributed to End Customers in the Novavax Territory during the immediately preceding calendar quarter, broken down by presentation (i.e., 5DV, UDV and PFS); (ii) the remainder payable to SLS with respect to such number of doses, which shall be equal to the difference between the Full Supply Price for such number of doses and the Risk Share Price paid for such number of doses (for example, with respect to the PFS presentation, [*** ] (the “Remainder Amount”); (iii) the number of doses of Drug Product, broken down by presentation (i.e., 5DV, UDV and PFS), that were delivered in accordance with Section 2.4 of this Supply Agreement (for which Novavax was invoiced and made partial payment at the Risk Share Price in accordance with clause (b)(i) of this Schedule 4.1.1) but that were destroyed in the [***] or otherwise determined by Novavax to be no longer distributable to End Customers (due to expiry or otherwise) (“Unsaleable Doses”); and (iv) if applicable, the number of doses of Drug Product for which Novavax was invoiced in [***] but for which neither a Remainder Amount has been paid (and for which a Remainder Amount is owing) nor a credit memo has been issued (and which are Unsaleable) as of the end of the [***] (until all doses of Drug Product for which Novavax has been invoiced have been accounted for as either distributed to End Customers or Unsaleable Doses). Novavax will remit to SLS the Remainder Amount owed as set forth in such report within [***] of SLS’s receipt of such written report. In addition, upon receipt of each such report, SLS will issue a credit memo to Novavax for the Unsaleable Doses in an amount equal to the difference between the Full Supply Price invoiced by SLS for the Unsaleable Doses and the Risk Share Price paid by Novavax for such Unsaleable Doses. Upon SLS’s written request, no more than [***] during the Term, Novavax shall (A) permit an independent, reputable professional accountant appointed by SLS (at SLS’s cost) and reasonably acceptable to Novavax, during normal business hours on no less than [***] prior written notice to Novavax and at a time and date to be agreed upon by the Parties (such agreement not to be unreasonably withheld), to have access to and review (but not copy) Novavax’s applicable sales records at Novavax’s applicable premises, solely to the extent necessary to enable such accountant to verify the accuracy of the [***] reports provided by Novavax pursuant this clause (c) of this Schedule 4.1.1 during the [***] period preceding such review (each, a “Records Review”), and (B) provide reasonable assistance to such accountant for its confirmation of the accuracy of such reports during such Records Review. Prior to receiving such access and performing such Records

Review, such accountant shall execute a confidentiality agreement on terms acceptable to Novavax and no less stringent than the confidentiality and non-use terms set forth in this Supply Agreement. Any records reviewed by such accountant during such Records Review shall constitute the Confidential Information of Novavax, and such accountant shall be permitted to disclose information furnished to such accountant during such Records Review solely to the extent necessary to convey to SLS its findings as to the accuracy of the applicable reports provided by Novavax under this Schedule 4.1.1 (a copy of which findings will be shared with Novavax at the time such findings are shared by the accountant with SLS).

(d)For clarity, unless and until Drug Product is distributed to an End Customer, the only Supply Price payable by Novavax for Drug Product Manufactured and supplied pursuant to this Agreement shall be the Risk Share Price. For further clarity, the Remainder Amount will be payable based on the number of doses of Drug Product distributed to End Customers, regardless of whether the End Customers sell or return such doses.

(e)SLS shall have the right, not more than [***] during the Term, to increase each Supply Price by no more than [***], solely for (i) inflation, by a percentage that is equal to the percentage increase in the [***] for the immediately preceding [***] period (the “PPI Inflation Rate”), and (ii) increases in Raw Materials costs or Manufacturing process costs; provided that, for clarity, regardless of SLS’s or its Authorized Manufacturer’s increased costs to Manufacture and supply Drug Substance or Drug Product, whether due to inflation or increased Raw Materials or processing costs, any such annual increase in a Supply Price shall not exceed [***] (each such annual increase, an “Annual Price Increase”). SLS shall provide Novavax at least [***] prior written notice of any such Annual Price Increase. Further, in the event of a material change in SLS’s cost structure (defined as raw material costs, consumables costs and processing costs increasing by greater than [***] above the annual PPI Inflation Rate) due to volume fluctuations and / or other force majeure events including the prevalent geopolitical scenarios, the Parties will discuss and negotiate in good faith to modify the pricing beyond the latest Annual Price Increase to reflect the material change in SLS’s cost structure. For the avoidance of doubt, any increased Supply Price shall not apply to any Product ordered under any Purchase Orders submitted prior to the effective date of such increase.
