authority as described below, to take the following actions on behalf of and in

Act of 1934 (the "Exchange Act") and the rules and regulations thereunder;

     (2)   seek or obtain, as the undersigned's representative and on the

and ratifies any such release of information; and

     (3)   do and perform any and all other acts which in the discretion of such
attorney-in-fact are necessary or desirable for and on behalf of the
undersigned in connection with the foregoing.

     The undersigned acknowledges that:

     (1)   this Power of Attorney authorizes, but does not require, each such
attorney-in-fact to act in their discretion on information provided to such
attorney-in-fact without independent verification of such information;

     (2)   any documents prepared and/or executed by any such attorney-in-fact
on behalf of the undersigned pursuant to this Power of Attorney will be in such
form and will contain such information and disclosure as such attorney-in-fact,
in his or her discretion, deems necessary or desirable;

     (3)   neither the Company nor any of such attorneys-in-fact assumes (i) any
liability for the undersigned's responsibility to comply with the requirements
of the Exchange Act, (ii) any liability of the undersigned for any failure to
comply with such requirements, or (iii) any obligation or liability of the
undersigned for profit disgorgement under Section 16(b) of the Exchange Act; and

     (4)   this Power of Attorney does not relieve the undersigned from
responsibility for compliance with the undersigned's obligations under the
Exchange Act, including without limitation the reporting requirements under
Section 16 of the Exchange Act.

     The undersigned hereby gives and grants each of the foregoing attorneys-in-
fact full power and authority to do and perform all and every act and thing
whatsoever necessary or appropriate to be done in the exercise of the rights and
powers granted by this Power of Attorney as fully to all intents and purposes as
the undersigned might or could do personally, hereby ratifying all that each
such attorney-in-fact, shall lawfully do or cause to be done for and on behalf
of the undersigned by virtue of this Power of Attorney.

     This Power of Attorney shall remain in full force and effect until revoked
by the undersigned in a signed writing delivered to each such attorney-in-fact
or until such earlier time as the undersigned is no longer required to file
Forms 3, 4, and 5 with respect to the Company.

     IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 12th day of August 2021.
