Schedule 1 attached thereto and replacing it with the new Schedule 1 attached
hereto; and (b) adding in proper numerical order the new Schedule 4 attached

with the new Exhibit D attached hereto.

     15. Deletion of Sections from the Credit Agreement. As of the Fifth
Amendment Effective Date or if later, as of the Assignment Effective Date, the
text of following sections shall be deleted in their entirety from the Credit
Agreement, and the words "Intentionally Deleted" shall be inserted in their
place:

     ss.8.1(f)(i) and (j)
     ss.8.d(h)(i)
     ss.8.3(i)
     ss.9.5.

     16. Consent to AFA Asset Swap. Each of the Banks hereby consents to the AFA
Swap, provided that (a) the cash consideration received by the Borrowers in
connection with the AFA Swap shall not be less than $1,500,000 and such
consideration shall be used to pay down the Term Loan, and (b) the Borrowers
shall comply with the terms of Section 8.4.1 with respect to the acquisition of
the Waste Disposal Services LLC assets.

     17. Consent to New Heights Equity Investment. Each of the Banks hereby
consents to the New Heights Equity Investment, provided that the stock of New
Heights owned by KTI Inc. shall be pledged to the Administrative Agent for the
benefit of the Banks.

     18. The MERC Transaction. In connection with the issuance of the MERC L/C
and the payment of all outstanding amounts under the ING Agreement, the ING
Lenders will assign all of their rights, interests and obligations under the ING
Documents to the Administrative Agent for the benefit of the Banks pursuant to
the Assignment and Acceptance dated the Assignment Effective Date between the
ING Lenders, ING and the Administrative Agent (on behalf of itself and the
Banks). As of the Assignment Effective Date, the ING Agreement shall be subsumed
under this Credit Agreement and shall be amended and restated and replaced in
its entirety by the terms of this Credit Agreement, and the ING Documents shall
be "Security Documents" under this Credit Agreement, and MERC will no longer be
an Excluded Subsidiary and will become a Borrower hereunder, and will execute
and deliver a Joinder and Affirmation to the Credit Agreement, allonges to the
Notes, and deliver such other documents as requested by the Administrative
Agent. Any cash held by ING shall be applied to pay down the outstanding
Domestic Revolving Credit Loans.

     If the MERC Transaction and the Assignment Effective Date occurs after the
Fifth Amendment Date, the Banks hereby consent to the MERC Transaction, on the
terms set forth in this ss.18, notwithstanding the restrictions in ss.8.4(j), as
amended hereby.

     19. Representations and Warranties. Each of the Borrowers represents and
warrants as follows:

          (a) The execution, delivery and performance of each of this Fifth
     Amendment and the Credit Agreement, as amended as of the date hereof and
     the transactions contemplated hereby and thereby are within the corporate
     power and authority of such Borrower and have been or will be authorized by
     proper corporate proceedings, and do not (a) require any consent or
     approval of the stockholders of such Borrower, (b) contravene any provision
     of the charter documents or by-laws of such Borrower or any law, rule or
     regulation applicable to such Borrower, or (c) contravene any provision of,
     or constitute an event of default or event which, but for the requirement
     that time elapse or notice be given, or both, would constitute an event of
     default under, any other material agreement, instrument or undertaking
     binding on such Borrower.

                                       -9-

          (b) This Fifth Amendment and the Credit Agreement as amended as of the
     date hereof and all of the terms and provisions hereof and thereof are the
     legal, valid and binding obligations of such Borrower enforceable in
     accordance with their respective terms except as limited by bankruptcy,
     insolvency, reorganization, moratorium or other laws affecting the
     enforcement of creditors' rights generally, and except as the remedy of
     specific performance or of injunctive relief is subject to the discretion
     of the court before which any proceeding therefor may be brought.

          (c) The execution, delivery and performance of this Fifth Amendment
     and the Credit Agreement as amended as of the date hereof and the
     transactions contemplated hereby and thereby do not require any approval or
     consent of, or filing or registration with, any governmental or other
     agency or authority, or any other party.

          (d) The representations and warranties contained in ss.6 of the Credit
     Agreement are true and correct in all material respects as of the date
     hereof as though made on and as of the date hereof.

          (e) After giving effect to this Fifth Amendment, no Default or Event
     of Default under the Credit Agreement has occurred and is continuing.

     20. Ratification, Etc. Except as expressly amended hereby, the Credit
Agreement, the other Loan Documents and all documents, instruments and
agreements related thereto are hereby ratified and confirmed in all respects and
shall continue in full force and effect. This Fifth Amendment and the Credit
Agreement shall hereafter be read and construed together as a single document,
and all references in the Credit Agreement or any related agreement or
instrument to the Credit Agreement shall hereafter refer to the Credit Agreement
as amended by this Fifth Amendment.

     21. GOVERNING LAW. THIS FIFTH AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     22. DELIVERY BY FACSIMILE. This Amendment, to the extent signed and
delivered by means of a facsimile machine, shall be treated in all manner and
respects as an original agreement or instrument and shall be considered to have
the same binding legal effect as if it were the original signed version thereof
delivered in person. At the request of any party hereto or to any such agreement
or instrument, each other party hereto or thereto shall re-execute original
forms thereof and deliver them to all other parties. No party hereto or to any
such agreement-or instrument shall raise the use of a facsimile machine to
deliver a signature or the fact that any signature or agreement or instrument
was transmitted or communicated through the use of a facsimile machine as a
defense to the formation of a contract and each party forever waives such
defense.

     23. Counterparts. This Fifth Amendment may be executed in any number of
counterparts and by different parties hereto on separate counterparts, each of
which when so executed and delivered shall be an original, but all of which
counterparts taken together shall be deemed to constitute one and the same
instrument.

     23. Effectiveness. This Fifth Amendment shall become effective (the "Fifth
Amendment Effective Date") upon the receipt by the Agent of:

          (a) a counterpart of this Fifth Amendment, executed by the Required
     Banks and the Borrowers;

          (b) an amendment fee in an aggregate amount equal to 20.0 basis points
     on the Commitment or outstanding principal portion of the Term Loan, as
     applicable, of each Bank which consents to this Fifth Amendment on or prior
     to 5:00 p.m. (Boston time) on February 20, 2001;

          (c) with respect to those provisions relating to new Borrowers
     including MERC, upon the signing and delivery a Joinder and Affirmation
     Agreement to the Administrative Agent, allonges to the Notes, and all
     documentation reasonably requested by the Administrative Agent in
     connection therewith; and

          (d) payment of all fees and expenses of the Administrative Agent's
     legal counsel in the connection with the preparation of this Fifth
     Amendment and ancillary documentation and filings.

<PAGE>
                                       -8-

the Borrowers. The Borrowers wish to eliminate any possibility that any past
conditions, acts, omissions, events, circumstances or matters would impair or
otherwise adversely affect any of the Administrative Agent's and the Banks'
rights, interests, contracts, collateral security or remedies. Therefore, each
of the Borrowers unconditionally releases, waives and forever discharges (x) any
and all liabilities, obligations, duties, promises or indebtedness of any kind
of the Administrative Agent or any Bank to any of the Borrowers, except the
obligations to be performed by the Administrative Agent or any Bank on or after
the date hereof as expressly stated in this Amendment, the Credit Agreement and
the other Loan Documents, and (y) all claims, offsets, causes of action, suits
or defenses of any kind whatsoever (if any), whether arising at law or in
equity, whether known or unknown, which the Borrowers might otherwise have
against the Administrative Agent, any Bank or any of its directors, officers,
employees or agents, in either case (x) or (y), on account of any past or

obligation, indebtedness, claim, cause of action, defense, circumstance or
matter of any kind.

delivered by means of a facsimile machine, shall be treated in all manner and
respects as an original agreement or instrument and shall be considered to have
the same binding legal effect as if it were the original signed version thereof
delivered in person. At the request of any party hereto or to any such agreement
or instrument, each other party hereto or thereto shall re-execute original
forms thereof and deliver them to all other parties. No party hereto or to any
such agreement or instrument shall raise the use of a facsimile machine to
deliver a signature or the fact that any signature or agreement or instrument
was transmitted or communicated through the use of a facsimile machine as a
defense to the formation of a contract and each party forever waives such
defense.

     18.  COUNTERPARTS. This Sixth Amendment may be executed in any number of
counterparts and by different parties hereto on separate counterparts, each of
which when so executed and delivered shall be an original, but all of which
counterparts taken together shall be deemed to constitute one and the same
instrument.

Amendment Effective Date") upon the receipt by the Agent of:
