Note paid in full  immediately  prior to the  effectiveness of this Agreement on
December 17, 1999.

     WHEREAS,  the  Borrowers,  the Banks (other than Wachovia Bank N.A.) are in

     required to be paid to the lessor under an Eligible Lease with each of such
     payments  discounted  to its present  value by applying a discount  rate to
     each payment equal to the lesser of (a) the  one-month  LIBO Rate in effect
     at the time of the calculation (including the LIBO Rate Applicable Margin),
     or (b) the Base Rate in effect  at the time of the  calculation;  provided,
     however,  that any payment  under an Eligible  Lease shall only be included
     for the purpose of  calculating  the Present Value of Lease Payments if (i)
     the  payment  is not yet due under the  Lease;  and (ii) the  lessee has no
     discretion as to whether or not to make the payment."

     2. Section 2.2 of Agreement.  Section 2.2 of the Agreement  shall be and is

Commitment  Percentage  in  effect  as a  result  of  this  Amendment,  and  (b)
application  of the proceeds of such Loans to  repayment to the other Banks,  in
their individual  capacities,  of Loans by each of them then in effect such that
the  aggregate  Loans of each Bank shall not exceed the  proportionate  share of
each Bank based on its Commitment  Percentage applied to the aggregate principal
amount of outstanding Loans by the Banks to the Borrowers on such date.

     11.   Counterparts.   This  Amendment  may  be  signed  in  any  number  of
