attorney-in-fact without independent verification of such information;

2. any documents prepared and/or executed by such attorney-in-fact on behalf of

3. neither the Company nor such attorney-in-fact assumes (i) any liability for
any of the undersigneds responsibility to comply with the requirements of the

executed by any of the undersigned for any of the purposes set forth herein.

        Although this Power of Attorney supersedes and replaces any prior power

the undersigned might or could do if present, hereby ratifying all that such
attorney-in-fact shall lawfully do or cause to be done of, for and on behalf of
any of the undersigned by virtue of this Power of Attorney.

        This Power of Attorney may be executed in several counterparts, each of
which shall be deemed an original but all of which shall constitute one and the
same instrument.

        This Power of Attorney shall remain in full force and effect until
revoked by any of the undersigned in a signed writing delivered to the
attorney-in-fact.

        IN WITNESS WHEREOF, the undersigned have each caused this Power of
Attorney to be executed as of 10/10/2023.
