        <footnote id="F1">This option award was previously reported based on having been approved by the issuer's board of directors on September 26, 2019, but such award was subject to shareholder approval of an increase in the number of shares available for issuance under the Novavax, Inc. Amended and Restated 2015 Stock Incentive Plan, as amended (the &quot;Plan&quot;). Such shareholder approval was received on June 25, 2020.</footnote>
        <footnote id="F2">Twenty-five percent (25%) of the shares subject to this option grant under the Plan will vest on the first anniversary of the September 26, 2019 grant date (the &quot;Grant Date&quot;), and the remaining seventy-five percent (75%) of the shares will vest in equal monthly installments over the following three (3) years, in each case subject to continued employment through such vesting date.</footnote>
        <footnote id="F3">Represents the previously reported September 26, 2019 stock appreciation right grant. The Form 4 filed by the reporting person on September 30, 2019 inadvertently stated that vesting of this grant was subject to shareholder approval of an increase in the number of shares available for issuance under the Plan. However, this grant was not subject to such shareholder approval.</footnote>
