        <footnote id="F1">This entry represents the number of shares of Viasat, Inc. common stock withheld by the Issuer to satisfy the tax withholding obligation of the Reporting Person.  These shares were not sold by the Reporting Person but were instead offset from the total number of vested shares received by the Reporting Person from the Issuer.</footnote>
        <footnote id="F2">The option becomes exercisable, if at all, based on both time-based vesting (in three increments equal to 33% of the total shares on each of the first three anniversary dates of the grant date) and performance-based vesting (if the average daily closing price of Viasat's common stock over any 45-day period during the three year period following the grant date exceeds certain stock price hurdles of $30.00 or above).</footnote>
        <footnote id="F3">The original deferred restricted stock unit grant was for 17,825 restricted stock units on 11/17/2020 Subject to the Reporting Person's election to defer the receipt of common stock, the units vest and convert into shares of common stock of the Issuer at a rate of 1/4 on the 13th month anniversary of the grant date; 1/4th on the second anniversary of the grant date; 1/4th on the third anniversary of the grant date and 1/4 on the fourth anniversary of the grant date.</footnote>
        <footnote id="F4">Until vested, the restricted stock unit shall be subject to forfeiture in the event of termination of employment or service with the Issuer.</footnote>
        <footnote id="F5">The original restricted stock unit grant was for 15,045 restricted stock units on 11/17/2021. Subject to the Reporting Person's election to defer the receipt of common stock, the units vest and convert into shares of common stock of the Issuer over a four year period commencing on 12/17/2022 and ending on 11/17/2025.</footnote>
