WITNESSETH

WHEREAS, pursuant to Section 27 of the Rights Agreement, the Company may from time to time, and the Rights Agent shall if the Company so directs in writing, supplement or amend the Rights Agreement without the approval of any holders of Right Certificates in order to cure any ambiguity, to correct or supplement any provision contained therein which may be defective or inconsistent with any other provisions therein, make any change to or delete any provision thereof or to adopt any other provisions with respect to the Rights which the Company may deem necessary or desirable; provided, that, from and after such time as any Person becomes an Acquiring Person, the Rights Agreement shall not be amended or supplemented in any manner which would adversely affect the interests of the holders of Rights (other than an Acquiring Person and its Affiliates and Associates); and

WHEREAS, the parties hereto desire to amend the Rights Agreement to advance the Final Expiration Date of the Rights to February 15, 2023.
