Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On September 14, 2021, the reporting person entered into a "zero-cost collar" arrangement (the "Transaction") pursuant to which he wrote European call options and purchased European put options over an aggregate of 400,000 shares of Series C common stock. Only one of the options can be in the money on the expiration date, at which time the in-the-money options will be exercised, and the other options will expire. If neither the put options nor the call options are the money on the expiration date, both the put and call options will expire. The Transaction will be settled in cash unless the reporting person elects physical settlement.
(2) The Transaction is divided into 5 components, each of which are with respect to 80,000 shares of Series C common stock. The components mature on sequential trading days over the period beginning on August 21, 2028 and ending on August 25, 2028.
(3) The Transaction is a "zero-cost collar" in which no premium was exchanged for either the call options or the put options.
