Because those shares were withheld due to an inadvertent error and the withholding transaction has been reversed, this amendment is being filed to remove the reference to such withholding transaction and to properly report the number of shares vested and held by the reporting person. Each restricted stock unit represents a contingent right to receive one share of common stock or, at the election of the Compensation Committee, the cash value thereof. These RSUs (i) vest on the date of the regularly scheduled annual meeting of the stockholders of the Company to be held in 2020, and (ii) are to be settled in cash or in shares of the Company's common stock, at the discretion of the Compensation Committee, as the administrator under the Plan. /s/ Jacqueline Perez-Ares, as Power of Attorney 2020-04-24
