     .   Gordon Mendelson has replaced Thomas Smith as President of APP. Mr.
         Mendelson will serve as President, Chief Operating Officer and Director
         of APP. Mr. Mendelson previously was Senior Vice President of Armstrong
         Service Inc., a division of Armstrong International Inc., APP's
         strategic industry partner and largest shareholder.

     .   Mark A. Margason, a founder of APP in April 1998, was appointed
