The Registrant hereby acknowledges that:

• should the Commission or the staff of the Commission, acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing;

• the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the Registrant from its responsibility for the adequacy and accuracy of the disclosure in the filing; and

The Registrant respectfully requests that it be notified of such effectiveness by a telephone call to Michael D. Waters (205) 244-5210, or in his absence to Alexandra C.
