The undersigned acknowledges that:

a) This Power of Attorney authorizes, but does not require, the
Attorney-in-Fact to act in his or her discretion on information
provided to such Attorney-in-Fact without independent verification
of such information;

b) Any documents prepared or executed by the Attorney-in-Fact on behalf of
the undersigned pursuant to this Power of Attorney will be in such form and
will contain such information as the Attorney-in-Fact, in his or her
discretion, deems necessary or desirable;

c) Neither the Company nor the Attorney-in-Fact assumes any liability for
the undersigned's responsibility to comply with the requirements of Section 13
or Section 16 of the Exchange Act or Rule 144, any liability of the undersigned
for any failure to comply with such requirements, or any liability of the
undersigned for disgorgement of profits under Section 16(b) of the
Exchange Act; and

d) This Power of Attorney does not relieve the undersigned from responsibility
for compliance with the undersigned's obligations under Section 13 or
Section 16 of the Exchange Act, including, without limitation, the

The undersigned hereby grants to the Attorney-in-Fact full power and authority
to do and perform each and every act and thing requisite, necessary or
advisable to be done in connection with the foregoing, as fully, to
all intents and purposes, as the undersigned might or could do in
person, hereby ratifying and confirming all that the Attorney-in-Fact,
or his or her substitute or substitutes, shall lawfully do or cause
to be done by authority of this Power of Attorney.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 4 or 5 or Schedules 13D

transactions in securities of the Company, unless earlier revoked by the
undersigned in a signed writing delivered to the Attorney-in-Fact. This
Power of Attorney revokes all previous powers of attorney with respect
to the subject matter of this Power of Attorney.

IN WITNESS WHEREOF, the undersigned has executed this Power of Attorney
as of February 26, 2025.
