The Company hereby acknowledges that:

Ÿshould the Securities and Exchange Commission (the “Commission”) or the Staff of the Commission (the “Staff”), acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the Registration Statement;

Ÿthe action of the Commission or the Staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the Company from its full responsibility for the adequacy and accuracy of the disclosure in the Registration Statement; and

Ÿthe Company may not assert Staff comments and the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

We understand that the Staff will consider this request as confirmation by the Company of its awareness of its responsibilities under the federal securities laws as they relate to the issuance of the securities covered by the Registration Statement.  If you have any questions regarding the foregoing, please contact John C.
