Dear Mr. Skinner:

Per our conversation today, the Company hereby requests an extension until December 15, 2005 to respond to the Staff’s letter dated November 17, 2005. The reasons for this extension request are due to the absence of key personnel during the Thanksgiving holiday, the AICPA/SEC December conference, and the need to consult with our outside appraisal firm. Please feel free to contact me if you have any questions or require any additional information with respect to the foregoing request.

Very truly yours,

Brian K. Miller
Senior Vice President and
Chief Financial Officer
