individual (hereinafter referred to as "Ms. Austin").

that certain Employment Agreement between her and American Building Control,
Inc. and MDI Operating, L.P. dated as of July 1, 2002 (the "Employment
Agreement").

Ms. Austin dated June 24, 2003, ABCX and Ms. Austin reached a final
understanding related to the separation of Ms. Austin from ABCX, including the
agreement on the part of ABCX to make the Separation Payments to Ms. Austin as
