     being hereinafter called the "REVOLVING LOAN COMMITMENT").  For
     purposes of determining the amount of Revolving Credit Loans
     outstanding, the Standby Letters of Credit issued pursuant to

     aggregate Revolving Credit Loans outstanding.  As provided below,
     Revolving Credit Loans may be requested by Willis, and made from time
     to time prior to the Revolver Termination Date.  All Loans shall be
     made to Willis at the main office of the Bank, Broad and Chestnut

     Equipment upon the physical removal of that engine from its airframe,
     provided that such Equipment otherwise qualifies as Category A
     Equipment."
