(1) On February 7, the reporting person was granted 79,481 restricted stock units, which represent a contingent right to receive one share of Issuer's common stock. The restricted stock units vest pursuant to the Vesting Schedule (as defined in footnote (2)) and are delivered to the reporting person upon vesting.
(2) The awards vest in equal monthly installments over three years, subject to the recipient's continued employment by the Issuer through the applicable vesting date, provided that, in lieu of the terms of any change in control agreement in place between the Issuer and the reporting person, in the event that the reporting person resigns for Good Reason (as defined in the recipient's change in control agreement) or is terminated without Cause (as defined in recipient's change in control agreement) within twelve months of a Change in Control (as defined in recipient's change in control agreement), 50% of the unvested portion of the awards will become immediately vested (the "Vesting Schedule").
(3) The original Form 4, filed on February 9, 2022, is being amended by this Form 4 amendment solely to correct an administrative error, which misstated the expiration date as February 6, 2025.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
