consolidation, the Debtor will develop an appropriate allocation of expenses
among the affiliated entities.

                      NOTE TO THE MONTHLY OPERATING REPORT:


         Consistent with the Debtor's historical accounting practices, this
         operating report accounts for all cash transfers among the Debtor and
         its affiliates and allocates some, but not all, of the expenses borne
         by one affiliate for the benefit of another or the others. In the
         absence of a decision for substantive consolidation, the Debtor will
         develop an appropriate allocation of expenses among the affiliated
         entities.

Consistent with the Debtor's historical accounting practices, this operating
report accounts for all cash transfers among the Debtor and its affiliates and
allocates some, but not all, of the expenses borne by one affiliate for the
benefit of another or the others. In the absence of a decision for substantive
consolidation, the Debtor will develop an appropriate allocation of expenses
among the affiliated entities.

Note: The premium for the Pollution Legal/Closure policy (AISLIC no. 8183013) is
billed in 5 annual installments of $19,280 (Pollution Legal) and $85,000
(Closure). To date, the first three installments are paid in full. The remaining
installments come due on the anniversary date. Thus, the remaining installments
for 12/15/98 and 1999 for Pollution and for 1/4/99 and 2000 for Closure, are
unbilled and unpaid.

                     NOTE TO THE MONTHLY OPERATING REPORT:


Consistent with the Debtor's historical accounting practices, this operating
report accounts for all cash transfers among the Debtor and its affiliates and
allocates some, but not all, of the expenses borne by one affiliate for the
benefit of another or the others. In the absence of a decision for substitute
consolidation, the Debtor will develop an appropriate allocation of expenses
among the affiliated entities.

                      NOTE TO THE MONTHLY OPERATING REPORT:

Consistent with the Debtor's historical accounting practices, this operating
report accounts for all cash transfers among the Debtor and its affiliates and
allocates some, but not all, of the expenses borne by one affiliate for the
benefit of another or the others. In the absence of a decision for substantive
consolidation, the Debtor will develop an appropriate allocation of expenses
among the affiliated entities.

         NOTE TO THE MONTHLY OPERATING REPORT:


         Consistent with the Debtor's historical accounting practices, this
         operating report accounts for all cash transfers among the Debtor and
         its affiliates and allocates some, but not all, of the expenses borne
         by one affiliate for the benefit of another or the others. In the
         absence of a decision for substantive consolidation, the Debtor will
         develop an appropriate allocation of expenses among the affiliated
         entities.

Note: The premium for the Pollution Legal/Closure policy (AISLIC no. 8183013) is
billed in 5 annual installments of $19,280 (Pollution Legal) and $85,000
(Closure). To date, the first three installments are paid in full. The remaining
installments come due on the anniversary date. Thus, the remaining installments
for 12/15/98 and 1999 for Pollution and for 1/4/99 and 2000 for Closure, are
unbilled and unpaid.
