To Whom It May Concern:

Re:	The James E. Stowers Twentieth Century Companies, Inc. Stock Trust Agreement

To Whom It May Concern:

I am counsel to the above-referenced Trust. James E. Stowers, Jr. was the initial Trustee of the Trust and has been continuously serving in that capacity. The purpose of this letter is to confirm that, pursuant to Section 6.1 of the Trust Agreement, Richard W. Brown has succeeded Mr. Stowers as the sole Trustee of the Trust, effective this date.

Please advise if you have any questions concerning the foregoing.

Very truly yours,
