The undersigned hereby constitutes and appoints each of Alvyn A. Schopp, Glen C. Warren, Jr., John Giannaula, Michael N. Kennedy and Yvette K. Schultz with full power of substitution, as the undersigned’s true and lawful attorney-in-fact to:
 
(1)                                  Execute for and on behalf of the undersigned a Form ID (including amendments thereto), or any other forms prescribed by the Securities and Exchange Commission, that may be necessary to obtain codes and passwords enabling the undersigned to make electronic filings with the Securities and Exchange Commission of the forms referenced in clause (2) below;

The undersigned hereby grants to the attorney-in-fact full power and authority to do and perform all and every act requisite, necessary or proper to be done in the exercise of any of the rights and powers granted herein, as fully to all intents and purposes as the undersigned might or could do if personally present, with full power of substitution or revocation, hereby ratifying and confirming all that the attorney-in-fact shall lawfully do or cause to be done by virtue of this Power of Attorney and the rights and powers granted herein.  The undersigned acknowledges that the attorney-in-fact, in serving in such capacity at the request of the undersigned, are not assuming
