Dear Mr. Rosenberg:

This letter is to acknowledge receipt of your letter to Dan Carmichael
dated December 20, 2005.

With respect to your request for our response within ten business days,
this would be very difficult for us to accomplish due to scheduling
conflicts over the holiday season.  As a result, we are committed to
providing you our written response by Tuesday, January 17, 2006.

If you have any questions or concerns with this timing, please contact
Deb Crane, SVP & General Counsel, at 513-603-2213, Keith Cheesman, VP
and Corporate Controller, at 513-603-2282, or myself at 513-603-2267.

Sincerely,



/s/Michael A. Winner
