(1)  Section 16(a) reports were filed for Mr. Prochnow from 1998 until early
     2000 at which time the Board of Directors of AMZ determined he was not an
     officer as defined in Section 16a-1(f); and, therefore, Mr. Prochnow ceased
     filing Section 16a reports.  No Section 16a reports were filed to indicate
     he exited the reporting system.  On 12/31/02 he became a Section 16 officer
     which prompted the filing of this Form 3.

*    If the Form is filed by more than one Reporting Person, see Instruction
     5(b)(v).

Reminder: Report on a separate line for each class of securities beneficially
          owned directly or indirectly.
