ITEM 5. OTHER EVENTS

MONTHLY OPERATING REPORTS FILED WITH UNITED STATES TRUSTEE

         On December 3, 1997, Molten Metal Technology, Inc. (the "Company") and
its subsidiaries filed a voluntary petition for reorganization under Chapter 11
of the U.S. Bankruptcy Code. The petition was filed in the U.S. Bankruptcy Court
for the District of Massachusetts (Eastern Division) (the "Bankruptcy Court").
The case numbers are as follows:

<TABLE>
         <S>                                         <C>         
         Molten Metal Technology, Inc.               97-21385-CJK
         MMT of Tennessee Inc.                       97-21386-CJK
         MMT Federal Holdings, Inc.                  97-21387-CJK
         M4 Environmental Management Inc.            97-21388-CJK
         M4 Environmental L.P.                       97-21389-CJK

</TABLE>

         Pursuant to Federal Rule of Bankruptcy Procedure 2015 and the United
States Trustee's Operating Guidelines and Reporting Requirements for Chapter 11
cases, each of the Company, MMT of Tennessee, Inc., MMT Federal Holdings, Inc.,
M4 Environmental Management Inc., and M4 Environmental, L.P. (collectively, the
"Companies") must file a Monthly Operating Report (MOR) with the Office of the
United States Trustee (Region One). The MOR for each of the Companies for the
month ending June 30, 1998, together with a consolidated report, were filed with
the Office of the United States Trustee on July 23, 1998. Copies of these MORs
are attached hereto as Exhibits 99.1 through 99.6 and are incorporated herein by
reference.

AMENDMENT OF POST-PETITION FINANCING AGREEMENT

         On March 9, 1998 the Company announced it had received approval from
the Bankruptcy Court for a $20 million loan facility from affiliates of Morgens,
Waterfall, Vintiadis & Company, Inc. (the "Lender"). The $20 million financing
was used to repay a short-term loan received from the Lender and has also
provided capital and operating funds to enhance the operations of the Company's
two operating plants in Oak Ridge, Tennessee. The loan will become due on
December 31, 1999 or the effective date of a Reorganization Plan for any of the
Companies, whichever is earlier. Execution of the $20 million Post-Petition
Medium-Term Financing agreement (the "Loan Agreement"), closing of the loan and
initial advance of funds was completed on March 20, 1998.

         The Loan Agreement includes, among other things, several financial and
operating covenants that require the Company to achieve certain standards as a
condition of the loan, including an "Earnings Before Interest, Taxes,
Depreciation and Amortization" ("EBITDA") covenant that obligates the Company to
maintain its EBITDA above certain specified levels on a cumulative monthly
basis, and a "Throughput" covenant that obligates the Company to maintain the
amount of ion exchange resin processed at the Company's Q-CEP facility in Oak
Ridge, Tennessee above certain specified levels, also on a cumulative monthly
basis.




<PAGE>   3



Failure to comply with any of the covenants in the Loan Agreement, including the
EBITDA and Throughput covenants, could constitute an Event of Default under the
Loan Agreement that would allow the Lender, among other things, to accelerate
repayment of the outstanding loan balance together with accrued interest.

         On July 20, 1998, the Company and the Lender executed Amendment No. 1
to the Loan Agreement ("Amendment No. 1"). Amendment No. 1 modifies the EBITDA
covenant and the Throughput covenant to reflect circumstances related to the
capital improvements program (the "Improvement Program") for the Company's Q-CEP
Facility in Oak Ridge, Tennessee (the Q-CEP Facility"). Amendment No. 1 modified
the EBITDA covenant and Throughput covenant only for the time period through
December 31, 1998. The EBITDA covenant and Throughput covenant for all time
periods in 1999, through the end of the term of the loan on December 31, 1999,
remain unchanged from those of the original Loan Agreement.

         The original covenants in the Loan Agreement assumed that a shutdown of
the Q-CEP Facility to allow completion of the Improvement Program would commence
in early May 1998 and last for approximately 4 weeks. In fact, the scheduled
shutdown began on May 27, 1998 and lasted approximately 6 weeks. The start of
the shutdown was delayed until necessary equipment was received on site. The
duration of the shutdown was longer than expected because demolition and
decontamination activities that were required prior to the installation of new
equipment took longer than expected.

         Having completed the Improvement Program, the Company is now in the
process of recommencing operations at the Q-CEP Facility. The intent of the
Improvement Program is to increase the throughput of the Q-CEP Facility by 60%
and lower its operating costs. The Company believes it will be able to determine
the efficacy of the Improvement Program during the third quarter of 1998.

STATUS OF THE COMPANY'S CEP FACILITY IN BAY CITY, TEXAS

         The Company owns a Catalytic Extraction Processing ("CEP") Facility in
Bay City, Texas (the "Bay City Facility"). The Bay City Facility is located on
property that the Company leased in May, 1995 from Hoechst Celanese Chemical
Group, Inc., predecessor in interest to Celanese Ltd. ("Celanese"). Construction
of the Bay City Facility was largely completed by November, 1997; however, the
Company was unable to commence operation of the Facility due to lack of
necessary start-up and operating funds.

         After filing for protection under Chapter 11, the Company began
actively searching for a partner or partners who could provide financial,
technical, operational, and/or management support that is required to start-up
and operate a chemical processing facility of this type. In June, 1998, the
Company concluded that it was unlikely to find such a partner or partners, and
on June 19, 1998 the Company filed with the Bankruptcy Court a motion to reject
its lease with Celanese. This motion to reject the lease was approved by the
Bankruptcy Court on July 8, 1998. Pursuant to the Bankruptcy Court's order
granting the




<PAGE>   4

lease rejection motion, the Company will have access to the property for a
period of up to two years to allow for orderly disposition of the Company's
property. The Company is currently evaluating all available options for
disposition of the Bay City Facility, including liquidation of the asset.

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.

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 all expenses
among the affiliated entities.

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

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

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 
                     substantive consolidation, the Debtor will develop
                     an appropriate allocation of all 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

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