This Confirming Statement ("Statement") confirms that the undersigned,

Eamonn P. Hobbs, has authorized, directed and designated each of Barbra Keck,

behalf of the undersigned with the U.S. Securities and Exchange Commission

(the "SEC") a Form ID, including amendments thereto, enabling the undersigned

to make electronic filings with the SEC of reports required by Section 16(a)

of the Securities Exchange Act of 1934 and any rule or regulation

thereunder; and (2) prepare, execute and file for and on behalf of the

The authority of the Designees under this Statement shall continue
