**RECITALS:**

WHEREAS, the Company and the Rights Agent have entered into that certain Rights Agreement, dated as of December 21, 2022 (as amended, restated, supplemented or otherwise modified prior to the date hereof, the "<u>Rights Agreement</u>");

WHEREAS, pursuant to <u>Section 27</u> of the Rights Agreement, the Company may supplement or amend any provision of the Rights Agreement in any respect in accordance with the provisions of such section; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3. <u>Counterparts</u>**. This Amendment may be signed in counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument.

The Rights Agreement as amended by this Amendment contains the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes and is in full substitution for any and all prior oral or written agreements and understandings between them related to such subject matter, and neither party hereto shall be liable or bound to the other party hereto in any manner with respect to such subject matter by any covenants or agreements except as specifically set forth in the Rights Agreement as amended by this Amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6. <u>Effective Date; Certification</u>**. Upon the execution and delivery of a counterpart hereof by each of the parties hereto this Amendment shall be deemed effective as of the date first written above (the "<u>Amendment Effective Date</u>"), as if executed on such date. The officer of the Company executing this Amendment hereby certifies to the Rights Agent that the amendment to the Rights Agreement set forth in this Amendment is in compliance with the terms of <u>Section 27</u> of the Rights Agreement and the certification contained in this <u>Section 6</u> shall constitute the certification required by <u>Section 27</u> of the Rights Agreement.
