        <footnote id="F1">Theses shares represent restricted units which, upon vesting, will be settled in units of CWAN Holdings LLC Interests (&quot;LLC Interests&quot;) and an equivalent number of noneconomic voting shares of Class B Common Stock. The reporting person will have the right to exchange his LLC Interests (together with the delivery for no consideration of an equal number of shares of Class B Common Stock) for an equal number of newly issued shares of Class A Common Stock, or, at the election of the Issuer, a cash payment equal to the 20-day volume weighted average price of shares of Class A Common Stock immediately prior to the applicable exchange date. The restricted units vest in four equal annual installments beginning on and including June 28, 2022.</footnote>
