Explanation of Responses:
(1)  On April 17, 2020, the reporting person was granted an option to purchase 400,000 shares of common stock of Novavax, Inc. (the "Company") pursuant to the Company's Amended and Restated 2015 Stock Incentive Plan, as amended. The vesting of the shares subject to this option grant is subject to the satisfaction of a performance-based vesting requirement, followed by time-based vesting. The performance metric required that the Company initiate a COVID-19 Phase 2 clinical trial within twelve (12) months of the grant date, which occurred when the Company initiated its Phase 2 clinical trial of NVX-CoV2373 in the U.S. on August 24, 2020. Following that event, fifty percent (50%) of the shares will vest on August 24, 2021, the first anniversary of the initiation date, and the remaining fifty percent (50%) of the shares will vest on August 24, 2022, the second anniversary of the initiation date, in each case subject to continued employment through such vesting date.
