The undersigned does hereby make, constitute and appoint Adam R. Kokas, Michael

agents and attorneys-in- fact (each hereinafter referred to as an "Attorney") to
act either together or alone in the name and on behalf of the undersigned for
and with respect to the matters hereinafter described.

Each Attorney shall have the power and authority to prepare, execute and file in
the name and on behalf of the undersigned Forms 3, 4 and Form 5 (or such other
forms as may be designated from time to time by the Securities and Exchange
Commission (the "Commission") for such purpose) or any amendments thereto
required to be filed with the Commission by the undersigned in accordance with
Section 16(a) of the Securities Exchange Act of 1934 in respect of the
undersigned's holdings of, and transactions in, equity securities (including

Each Attorney is hereby authorized to execute and deliver all documents,
acknowledgments, consents and other agreements and to take such further action
as may be necessary or convenient in order to more effectively carry out the
intent and purposes of the foregoing.

The Power of Attorney conferred hereby is not delegable by any Attorney. Each
Attorney shall serve without compensation for acting in the capacity of agent
and attorney-in-fact hereunder.

The undersigned hereby ratifies, confirms and adopts as the undersigned's own
act and deed all action lawfully taken by the Attorneys, or any of them,
pursuant to the power and authority herein granted.

This Power of Attorney shall be governed by, and construed in accordance with,
the laws of the State of New York and shall remain in full force and effect
until the undersigned is no longer required to file Forms 3, 4 and 5 with the
Commission, unless earlier revoked by the undersigned in a signed writing
delivered to any of the foregoing Attorneys.

IN WITNESS WHEREOF, the undersigned has set her hand this 5th day of May, 2021.
