resubstitution to sign in his or her name, place and stead, in any and all capacities, and to do any and all things and execute any and all instruments that such attorney may deem necessary or advisable under the Securities Exchange Act of 1934, as
amended, and any rules, regulations and requirements of the Securities and Exchange Commission (the Commission), in connection with the filing with the Commission of an Annual Report on Form 10-K of the Company for the fiscal year ended
