Item 5. Other Events

      On July 10, 1998, KTI, Inc. (the "Company" or the "Registrant") and
certain of its subsidiaries, collectively, the "Borrowers", entered into a $150
million Revolving Credit Agreement (the "Revolving Credit Agreement") with
KeyBank, National Association ("KeyBank"), both individually and as agent for
other financial institutions. The Revolving Credit Agreement replaces the prior
Revolving and Term Loan and Security Agreement (the "Loan and Security
Agreement") with KeyBank, individually. The Loan and Security Agreement provided
for a revolving line of credit for $30 million and a term loan of $7.5 million.

The Revolving Credit Agreement has the following principal terms:

A.    The Revolving Credit Agreement may be used for general working capital
      purposes, issuance of letters of credit and for acquisitions. (Up to $15
      million under the Revolving Credit Agreement may be used for the issuance
      of letters of credit.) Information packages must be submitted to the
      Lenders on acquisitions with a cost of $5 million or more (such cost
      includes, without limitation, any debt assumed with the assets acquired or
      owed by any acquired company in the case of a stock purchase and covenants
      not to compete, but does not include any "earnout" or other contingent
      payments). Acquisitions with a cost of $10 million or more require
      approval from Lenders holding in aggregate not less than a 75%
      participation in the Revolving Credit Agreement.

B.    Loans may be obtained by any Borrower, based on either the Base Rate of
      KeyBank or on LIBOR, at the Borrower's option. All loans are the joint and
      several obligation of each Borrower. The actual rates paid on each Loan
      will vary, depending on the ratio of total senior funded debt to
      consolidated adjusted EBITDA, as determined from time to time.

C.    The Revolving Credit Agreement terminates on April 30, 2001.

D.    The Revolving Credit Agreement is secured by all of the assets of the
      Company (other than certain assets pledged to third party lenders and the
      stock of the Company's K-C International, Ltd. subsidiary) and all of the
      assets (other than certain assets pledged to third party lenders) of the
      Company's subsidiaries, other than Data Destruction Services, Inc.; K-C
      International, Ltd., KTI Environmental Group, Inc.; Maine Energy Recovery
      Company, Limited Partnership; Penobscot Energy Recovery Company, Limited
      Partnership and Timber Energy Resources, Inc. Timber Energy Resources,
      Inc. issued its guaranty to KeyBank in connection with the Revolving
      Credit Agreement. KTI Environmental Group, Inc. has pledged its limited
      partnership interest in PERC Management Company Limited Partnership.

            WHEREAS, the Lenders severally agree, upon the terms and conditions
set forth herein, to lend such amounts to, and take participations in such
letters of credit for the account of, the Borrower.

            NOW, THEREFORE, in consideration of the premises, and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the Lenders, the Agent and the Borrower hereby agree as follows:

            ARTICLE 1. DEFINITIONS

            Section 1.1 Defined Terms. As used in this Agreement, the following
terms shall have the following meanings:

            "Acquisition" shall mean any transaction or series of transactions

of the securities having ordinary voting power for the election of directors of
such Person or (b) direct or cause the direction of the management and policies
of such Person whether by contract or otherwise.

            "Agent" shall mean (a) KeyBank National Association; or (b) such
other bank or financial institution as shall have been subsequently appointed as
successor Agent pursuant to Section 8.3 of this Agreement.

            "Agreement" shall mean this Revolving Credit Agreement, as amended,
supplemented or otherwise modified from time to time.

            "Applicable Margin" shall mean a rate per annum determined in

the sum of (a) the aggregate principal amount of all then outstanding Revolving
Credit Loans made by such Lender and (b) the amount of such Lender's Percentage
of the Letter of Credit Outstandings at such time.

            "Base Rate" shall mean the rate of interest per annum publicly
announced from time to time by KeyBank as its Prime or Base Rate in effect at

KeyBank in connection with extensions of credit to debtors. Changes in the rate
of interest on that portion of any Loans maintained as Base Rate Loans and on
Reimbursement Obligations shall become effective as of the opening of business
on the day on which each such change in the Base Rate is established. The Agent

with GAAP consistent with those applied in preparation of the financial
statements referred to in Section 5.1 hereof to acquisitions during such period
by KTI and/or its consolidated Subsidiaries of any tangible asset, or
replacements or substitutes therefor or additions thereto which are treated as a
non current asset on such financial statements, including, without limitation,
the acquisition or construction of assets having a useful life of more than one
year, but excluding costs attributed to any Acquisition.

            "Capital Lease Obligations" shall mean for any Person for any
period, the obligations of such Person to pay rent and other amounts under any

of such Person under GAAP.

participations or other equivalents (however designated) of capital stock of any

Commitment. Each Lender is hereby authorized to record the date, Type and amount

or a portion thereof to another Type, the date and amount of each payment or
prepayment of principal thereof and, in the case of Eurodollar Loans, the length

recorded. Each Revolving Credit Note shall (x) be dated the Closing Date, (y) be
stated to mature on the Maturity Date and (z) provide for the payment of
interest in accordance with Section 2.9.

            Section 2.3 Procedure for Revolving Credit Borrowings.

                  (a) The Borrower may borrow under the Commitment for Revolving
Credit Loans prior to the Maturity Date on any Business Day. The Borrower shall
give the Agent irrevocable notice (which notice must be received by the Agent
prior to 10:00 a.m., New York time, two Working Days prior to the requested
Borrowing Date, if all or any part of the requested Revolving Credit Loans are
to be initially Eurodollar Loans and one Business Day prior to the requested
Borrowing Date in the case of the initial Base Rate Loan and otherwise by 12:00
noon on the date of the requested Base Rate Loan), specifying (1) the amount to
be borrowed, (2) the requested Borrowing Date, (3) whether the borrowing is to
be of Eurodollar Loans or Base Rate Loans or a combination thereof and (4) if
the borrowing is to be entirely or partly of Eurodollar Loans, the amount of
such Loans and the length of the initial Interest Period therefor. Each
Revolving Credit Loan shall be in an amount equal to $3,000,000 or a whole
multiple of $500,000 in excess thereof. The Agent shall promptly notify the
Lenders of its receipt of any such irrevocable notice of borrowing from the
Borrower.

                  (b) On or before 12:00 noon New York time on the Business Day
specified in the Borrower's notice of borrowing, each Lender shall provide the
Agent with funds at the Payment Office in an amount equal to such Lender's
Percentage of the requested borrowing. The proceeds of each borrowing shall be
made available by the Agent to the Borrower pursuant to Section 2.11(d). No
Lender's obligation to make any Loan shall be affected by any other Lender's
failure to make any Loan. Neither


                                       21
<PAGE>   27

the Agent nor any Lender shall have any liability for the failure of any Lender
(other than itself) to fund a Loan.

                  (c) With respect to any Loan, unless the Agent shall have been
notified in writing by any Lender prior to the date of making such Loan that
such Lender does not intend to make available to the Agent such Lender's portion
of the Loan to be made on such date, the Agent may (but shall not be obligated
to) assume that such Lender has made such amount available to the Agent on that
date and, in reliance on such assumption, the Agent may make available to the
Borrower a corresponding amount. If such amount is not made available by such
Lender to the Agent on the date of making such Loan, such Lender shall be
obligated to pay such amount to the Agent and shall pay to the Agent on demand
interest on such amount at the Federal Funds Rate for the number of days from
and including the date of making such Loan to the date on which such Lender's
portion of the Loan becomes immediately available to the Agent. The Agent shall
also be entitled to recover such amount, with interest thereon at the rate per
annum then applicable to the Loans comprising such borrowing, upon demand, from
the Borrower. A statement of the Agent submitted to any Lender with respect to
any amounts owing under this Section 2.3(c) shall be conclusive and binding in
the absence of demonstrable error. Nothing in this Section 2.3(c) shall be
deemed to relieve any Lender from its obligation to fulfill its Commitments
hereunder.

                  (a) The Borrower agrees to pay to the Agent for the benefit of
and disbursement to the Lenders a commitment fee in respect of the Commitments
to make Revolving Credit Loans, for the period from and including the date
hereof to the Maturity Date, computed at the rate of .25% per annum, calculated
on the basis of a 360-day year for the actual days elapsed, on the average daily
amount of the aggregate Commitments (whether or not used) during the period for
which payment is made, payable quarterly in arrears on the last day of each
March, June, September and December and on the Maturity Date or such earlier
date as the Commitments shall terminate as provided herein, commencing on the
first of such dates to occur after the date hereof.

                  (b) The Borrower agrees to pay to the Agent for the benefit of
and disbursement to the Lenders a letter of credit fee in respect of each Letter
of Credit, for the period from and including the date of issuance of such Letter
of Credit to its Stated Expiry Date, computed at the rate of 1_% per annum,
calculated on the basis of a 360-day year for the actual days elapsed, on the
average daily amount of the available amount of such Letter of Credit during the
period for which payment is


                                       22
<PAGE>   28

made, payable quarterly in advance on the date of, and as a condition precedent
to, the issuance of such Letter of Credit and thereafter on the last day of each
March, June, September and December occurring prior to the Stated Expiry Date of
such Letter of Credit

            Section 2.5 Termination or Reduction of Commitments.

                  (a) KTI shall have the right, upon not less than three
Business Days' written notice to the Agent, to terminate the Revolving Loan
Commitments or, from time to time, to reduce the amount of such Commitments,
provided that at no time may the Revolving Loan Commitments be reduced by the
Borrower to an amount less than the sum of the outstanding principal amount of
Revolving Credit Loans and Letter of Credit Outstandings. Any such reduction
shall be in an amount equal to $5,000,000 or a whole multiple of $1,000,000 in
excess thereof and shall reduce permanently the Revolving Loan Commitments then
in effect. Any such reduction in the Revolving Loan Commitment shall be binding
on the Subsidiary Borrowers whether or not they have notice thereof.

                  (b) Each reduction in the Revolving Loan Commitments, whether
voluntary or otherwise, shall be permanent and irrevocable. All reductions in
the Revolving Loan Commitments shall be made pro rata to the Commitments of the
Lenders. The Agent shall promptly notify each Lender of the amount of any
reduction of its Commitment.

whole or in part, subject to the provisions of Section 2.14 but otherwise
without premium or penalty, upon at least one Business Days' irrevocable notice
to the Agent (except in the case of prepayments required pursuant to Section
2.6(c) for which no notice is required), specifying the date and amount of
prepayment and the Loans (by Type and, if applicable, Tranche) to be prepaid. In
the event Borrower does not specify which Loans are to be prepaid, prepayments
shall be applied first to outstanding Base Rate Loans (together with accrued and
unpaid interest on the amount prepaid to the date of prepayment), second to
outstanding Reimbursement Obligations and third to outstanding Eurodollar Loans
(together with accrued and unpaid interest on the amount prepaid to the date of
prepayment). Prepayments of Eurodollar Loans shall be subject to the provisions
of Section 2.14. Partial prepayments shall be in an aggregate principal amount
of $1,000,000 or a whole multiple of $500,000 in excess thereof or if such
prepayment would reduce the principal amount of a Eurodollar Tranche below
$1,000,000, in an aggregate principal amount equal to the outstanding principal
amount of such Tranche. All prepayments shall be allocated to the Lenders based
on their respective Percentages.

                  (b) If any notice of prepayment is given, the amount specified
in such notice shall be due and payable on the date specified therein.
Prepayments of the Loans shall be accompanied by payment of accrued interest to
the payment date on the principal amount prepaid.

                  (c) In the event (i) the aggregate outstanding principal
amount of the Revolving Credit Loans and Reimbursement Obligations and (ii)
Letter of Credit Outstandings (excluding Reimbursement Obligations) exceeds the
Commitments at any time, the Borrower shall, on or before 3:00 p.m. on the first
Business Day after such excess is established by the Agent in writing, prepay
the Revolving Credit Loans and Reimbursement Obligations in an amount equal to
such excess (together with interest on the amount prepaid to the date of
prepayment). If such excess is greater than the outstanding principal amount of
Revolving Credit Loans and Reimbursement Obligations, the Borrower shall, in
addition, post cash collateral with the Agent to secure repayment of the Letter
of Credit Outstandings in an amount equal to the balance of such excess. Any
such prepayments shall be subject to the provisions of Section 2.14.

                  (d) The Agent shall disburse all prepayments of the Loans to
the Lenders on a pro rata basis.

Rate Loan may be converted to a Eurodollar Loan when any Event of Default has
occurred and is continuing;

                  (d) any portion of a Eurodollar Loan that cannot be converted
into or continued as a Eurodollar Loan by reason of Section 2.7(b) or 2.7(c) or
otherwise automatically shall be converted at the end of the Interest Period in
effect for such Loan to a Base Rate Loan;

                  (e) on the last day of any Interest Period for Eurodollar
Loans, if the Borrower has failed to give notice of conversion or continuation
as described in this subsection or if such conversion or continuation is not
permitted pursuant to Section 2.7 or otherwise, such Loans shall be converted to
Base Rate Loans on the last day of such then expiring Interest Period;

                  (f) accrued interest on a Loan (or portion thereof) being
converted shall be paid by the Borrower at the time of conversion.

            Section 2.8 Minimum Amounts of Tranches. All borrowings, conversions
and continuations of Loans hereunder and all selections of Interest Periods
hereunder shall be in such amounts and be made pursuant to such elections that,
after giving effect thereto, the aggregate principal amount of the Loans
comprising each Eurodollar Tranche shall be equal to $1,000,000 or a whole
multiple of $500,000 in excess thereof.

            Section 2.9 Interest Rates and Payment Dates.

                  (a) Subject to the provisions of Section 2.9(c), each Base
Rate Loan shall bear interest at a rate per annum (computed on the basis of the
actual number of days elapsed over a year of 360 days and twelve 30-day months)
equal to the Base Rate plus the Applicable Margin.

                  (b) Subject to the provisions of Section 2.9(c), each
Eurodollar Loan shall bear interest (computed on the basis of the actual number
of days elapsed over a year of 360 days) at a rate per annum equal to the
Eurodollar Rate for the Interest Period in effect for such Eurodollar Loan plus
the Applicable Margin in effect for such Interest Period.

                  (c) If all or a portion of (A) the principal amount of any
Loan, (B) any interest payable thereon or (C) any commitment fee or other amount
payable hereunder shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), such overdue amount shall, upon notice to the
Borrower from the Agent, bear interest at a rate per annum which is

                        (1) in the case of overdue principal, the rate that
                  otherwise would be applicable thereto pursuant to the
                  foregoing provisions of this subsection plus 4% per annum, or

                        (2) in the case of overdue interest or fees or other
                  amounts, the Base Rate plus 4%,

in each case from the date of such nonpayment until such amount is paid in full
(before and, to the extent permitted by law, after judgment).

                  (d) Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing on overdue amounts pursuant to
Section 2.9(c) shall be payable on demand.

                  (e) As soon as practicable the Agent shall notify the Borrower
and the Lenders of (A) each determination of a Eurodollar Rate, each change in
the Base Rate and the Applicable Margin and (B) the effective date and the
amount of each change in the interest rate on a Loan. Each determination of an
interest rate by the Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of clearly
demonstrable error. At the request of the Borrower, the Agent shall deliver to
the Borrower a statement showing the quotations used by the Agent in determining
any interest rate pursuant to Sections 2.9(a), (b) or (c).

            Section 2.10 Inability to Determine Interest Rate. If prior to the
first day of any Interest Period:

                  (a) the Agent shall have determined (which determination shall
be conclusive and binding upon the Borrower) that adequate and reasonable means
do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

                  (b) a Lender notifies the Agent and Borrower that the
Eurodollar Rate determined or to be determined for such Interest Period will not
adequately and fairly reflect the cost to such Lender of making or maintaining
the Eurodollar Loans during such Interest Period, or

                  (c) The Agent shall have determined (which determination shall
be conclusive and binding upon the Borrower) that Dollar deposits in the
principal amounts of the Eurodollar Loans to which such Interest Period is to be
applicable are not generally available in the London Interbank Market,

the Agent shall give notice thereof to the Borrower as soon as practicable
thereafter. If such notice is given (A) any Eurodollar Loans requested to be
made on the first day of such Interest Period shall be made as Base Rate Loans,
and (B) any Loans that were to have been converted to or continued as Eurodollar
Loans on the first day of such Interest Period shall be converted to or
continued as Base Rate Loans. Until such notice has been withdrawn by the Agent,
no Loans shall be made as or converted to or continued as Eurodollar Loans.

            Section 2.11 Payments/Funding.

                  (a) All payments (including prepayments) made by the Borrower
hereunder and under the Notes, whether on account of principal, interest, fees,
Reimbursement Obligations or otherwise, shall be made without set off or
counterclaim and shall be made prior to 12:00 noon, New York time, on the due
date thereof to the Agent, for the account of the Lenders in Dollars and in
immediately available funds to the Agent's account at such address as the Agent
shall give notice to the Borrower and the Lenders (the "Payment Office"). Except
for payments received by the Agent for the account of the Agent in its capacity
as such, or for the account of a specific Lender in accordance with the
provisions of this Agreement, the Agent shall distribute like funds relating to
the payment of principal, interest or fees pro rata to the Lenders (based on
their Percentages) to which such payment is due and payable for their accounts
and at the addresses as each such Lender shall specify in its notice to the
Agent made in accordance with Section 10.2 of this Agreement.

                                       27
<PAGE>   33

                  Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due to the Lenders hereunder that the
Borrower will not make such payment in full, the Agent may (but shall not be
obligated to) assume that the Borrower has made such payment in full to the
Agent on such date, and the Agent may, in reliance upon such assumption, cause
to be distributed to each Lender on such due date an amount equal to the amount
then due such Lender. If and to the extent the Borrower shall not have so made
such payment in full to the Agent, each Lender shall repay to the Agent
forthwith on demand the amount distributed to such Lender together with interest
thereon, at the rate equal to the Federal Funds Rate, for each day from the date
such amount is distributed to such Lender until the date such Lender repays such
amount to the Agent.

                  (b) If any principal payment hereunder (other than payments on
Eurodollar Loans) becomes due and payable on a day other than a Business Day,
such payment date shall be extended to the next succeeding Business Day, and
interest thereon shall be payable at the then applicable rate during such
extension. If any payment on a Eurodollar Loan becomes due and payable on a day
other than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day (and interest shall accrue during such extension of
time) unless the result of such extension would be to extend such payment into
another calendar month, in which event such payment shall be made on the
immediately preceding Business Day.

                  (c) If on any date a payment is due hereunder, the Borrower
shall pay less than the amount stated to be due or on any date the Agent shall
receive any payment under any Security Document or pursuant to any proceeding to
enforce the Obligations of any Person constituting the Borrower, such proceeds
shall be distributed to the Lenders pro rata based on their respective
Percentages and shall be applied first to costs of collection incurred by each
Lender, second to accrued and unpaid interest, third to principal and then to
the payment of any other amounts due hereunder or the other Loan Documents.

                  (d) The Agent shall fund each Loan by depositing the amount
thereof in the joint account (the "Account") of KTI and the Subsidiary Borrowers
(account no. 1910-1400-1538) at KeyBank; provided that the proceeds of each Loan
shall first be applied to principal prepayments or payments due on the date of
such Loan (without derogating from the Borrower's obligation to repay) and
proceeds of any conversion or continuation of a Loan to or as a particular Type
shall be applied by the Agent solely to effect such conversion or continuation.
Each Lender is hereby authorized to debit the accounts of each Person
constituting the Borrower for all payments due hereunder; provided the foregoing
shall not derogate from the Borrower's obligation to pay or

                                       28
<PAGE>   34

restrict any Lender's recourse to any particular fund or source of monies; and
provided further, each Lender agrees not to debit such accounts for amounts
payable pursuant to Sections 2.13, 2.14 or 10.5 unless an Event of Default has
occurred and is continuing. The Borrower agrees to maintain its primary
depository accounts with KeyBank's office at 66 South Pearl Street, Albany, New
York.

            Section 2.12 Change in Legality. Notwithstanding any other provision
herein, if any change in any Requirement of Law or in the interpretation or
application thereof by a Governmental Authority shall make it unlawful for a
Lender to make or maintain Eurodollar Loans as contemplated by this Agreement,
(a) the Commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert Loans to Eurodollar Loans shall be canceled
forthwith and (b) such Loans then outstanding as Eurodollar Loans, if any,
automatically shall be converted to Base Rate Loans on the respective last days
of the then current Interest Periods with respect to such Loans or within such
earlier period as required by law. If any such conversion of a Eurodollar Loan
occurs on a day which is not the last day of the then current Interest Period
with respect thereto, the Borrower shall pay to such Lender such amounts, if
any, as may be required pursuant to Section 2.14.

            Section 2.13 Increased Costs.

                  (a) If the adoption of, or any change in, any Requirement of
Law or in the interpretation or application thereof by a Governmental Authority
or compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

                        (1) shall subject any Lender to any tax of any kind
                  whatsoever with respect to this Agreement, any Note or any
                  Eurodollar Loan made by it, or change the basis of taxation of
                  payments to such Lender in respect thereof (except for the
                  imposition of and changes in the rate of tax on the overall
                  net income of the Lender);

                        (2) shall impose, modify or hold applicable any reserve,
                  special deposit, compulsory loan or similar requirement
                  against assets held by, deposits or other liabilities in or
                  for the account of, advances, loans or other extensions of
                  credit by, or any other acquisition of funds by, any office of
                  a Lender which is not otherwise included in the determination
                  of the Eurodollar Rate hereunder, including, without
                  limitation, the

                                       29
<PAGE>   35

                  imposition of any reserves with respect to Eurocurrency
                  Liabilities under Regulation D of the Board; or

                        (3) shall impose on a Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans hereunder or to reduce any amount
receivable hereunder in respect thereof then, in any such case, the Borrower
shall promptly pay such Lender, upon its demand, any additional amounts
necessary to compensate such Lender for such increased cost or reduced amount
receivable. If a Lender becomes entitled to claim any additional amounts
pursuant to this subsection, it shall promptly notify the Agent and the Borrower
of the event by reason of which it has become so entitled. A certificate as to
any additional amounts payable pursuant to this subsection submitted by a Lender
to the Borrower and Agent shall be conclusive in the absence of clearly
demonstrable error. This covenant shall survive the termination of this
Agreement and the payment of the Notes and all other amounts payable hereunder.

                  (b) In the event that a Lender shall have determined that any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof does or shall have the effect of
reducing the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which such Lender
or such corporation could have achieved but for such change or compliance
(taking into consideration Lender's or such corporation's policies with respect
to capital adequacy) by an amount deemed by such Lender to be material, then
from time to time, after submission by such Lender to the Borrower (with a copy
to the Agent) of a written request therefore, the Borrower shall pay to such
Lender such additional amount or amounts as will compensate such Lender for such
reduction.

                  (c) In the event that by reason of any change in any
Requirement of Law (including, without limitation, the lapse or termination of
any treaty) or in the interpretation thereof, or the adoption of any new law,
regulation or requirement by any Governmental Authority, or the imposition of
any requirement of any central bank whether or not having the force of law, (i)
the Agent or any Lender shall, with respect to this Agreement, the Loans, the
Letters of Credit (or risk participations therein),

                                       30
<PAGE>   36

the Reimbursement Obligations (or risk participations therein), the Notes or its
obligation to make Loans or issue and/or own risk participations in Letters of
Credit under this Agreement, be subjected to any withholding or other tax, levy,
impost, charge, fee, duty or deduction of any kind whatsoever (other than
franchise taxes imposed by the jurisdiction in which the Agent or such Lender is
domiciled and other than any tax generally imposed or based upon the net income
or branch profits of the Agent or such Lender) (collectively, "Taxes") or (ii)
any change shall occur in the taxation of the Agent or such Lender with respect
to any Loan, any Reimbursement Obligation (or any risk participation therein),
the interest payable thereon or any fees payable hereunder or referred to herein
(other than franchise taxes imposed by the jurisdiction in which the Agent or
such Lender is domiciled and other than any change which affects, and to the
extent that it affects, the taxation of the net income or branch profits of the
Agent or such Lender), and if any such measures or any other similar measure
shall result in an increase in the cost to the Agent or such Lender of making or
maintaining any Loan or any Letter of Credit or a reduction in the amount of
principal, interest or fees receivable by the Agent or such Lender in respect
thereof, the Agent or such Lender promptly after learning of the imposition of
such cost or reduction in any amount shall notify the Borrower and the Agent (if
applicable) stating the reasons therefor. The Borrower shall thereafter pay to
the Agent or such Lender, upon demand from time to time, as additional
consideration hereunder, such additional amounts as will fully compensate the
Agent or such Lender for such increased costs or reduced amounts and shall
promptly provide the Agent or such Lender, as the case may be, with official tax
receipts or other evidence of the payment of any taxes paid by the Borrower. A
certificate as to the increased costs or reduced amounts setting forth the
calculations therefor, shall be submitted promptly by the Agent or such Lender
to the Borrower and the Agent (if applicable) and, in the absence of
demonstrable error, shall be conclusive and binding as to the amount thereof. If
the Agent or Lender receives any additional amounts from the Borrower pursuant
to this subsection (c) if requested by Borrower, the Agent or such Lender shall
(at the Borrower's expense) use its best efforts to obtain a refund, reduction,
deduction or credit for any Taxes with respect to the additional amounts paid
under this subsection (c). If the Agent or such Lender actually receives or
enjoys the benefit of any such refund, reduction, deduction or credit for any
such Taxes, the Agent or such Lender shall reimburse the Borrower if and to the
extent, but only the extent, that the Agent or such Lender determines that it
has actually received (i) a refund of taxes or other amounts (together with any
interest actually received thereon from the respective Governmental Authority)
which refund is attributable to the Taxes with respect to which such additional
amounts were paid; or (ii) an effective net reduction (through a reduction,
deduction,

                                       31
<PAGE>   37

credit or otherwise) in any taxes or other amounts otherwise payable by the
Agent or such Lender (including any taxes imposed on or measured by the net
income of the Agent or such Lender), which reduction is attributable to the
Taxes with respect to such additional amounts were paid. If, at any time after
the Agent or such Lender makes a payment to the Borrower pursuant to the
preceding sentence, the Agent or such Lender determines that it was not entitled
to the full amount of any refund (together with the interest thereon) reimbursed
to the Borrower as aforesaid or that its taxes are not reduced by a credit or
deduction for the full amount of Taxes reimbursed to the Borrower as aforesaid,
the Borrower upon the demand of the Agent or such Lender will promptly pay to
the Agent or such Lender the amounts so refunded to which the Agent or such
Lender was not so entitled, or the amount by which the taxes of the Agent or
such Lender were not so reduced, as the case may be.

                  (d) Notwithstanding any other provision of this Section 2.13,
no Lender shall demand compensation for any increased cost or reduction referred
to in this Section 2.13 if it shall not at the time be the general policy of
such Lender to demand such compensation in similar circumstances under
comparable provisions of other credit agreements, and each Lender shall in good
faith endeavor to allocate increased costs or reductions fairly among all of its
affected commitments and credit extensions (whether or not it seeks compensation
from all affected borrowers). The protection of this Section 2.13 shall be
available to each Lender regardless of any possible contention of the invalidity
or inapplicability of the law, rule, regulation, guideline or other change or
condition which shall have occurred or been imposed.

                  (e) If Borrower is required to pay additional amounts under
this Section 2.13, the Borrower may, at its own expense, require such Lender to
transfer and assign in whole or in part, without recourse all or part of its
interests, rights and obligations under this Agreement to an assignee (which may
be another Lender, if a Lender accepts such assignment) which shall assume such
assigned obligations in a writing in form and substance reasonably acceptable to
the Agent; provided that (i) such assignment shall not conflict with any law,
rule or regulation or order of any court or other Governmental Authority, (ii)
the Borrower shall have received a written consent of the Agent in the case of
any entity that is not a Lender, which consent shall not be unreasonably
withheld, and (iii) the Borrower or such assignee shall have paid to the
assigning Lender in immediately available funds the principal of, and interest
accrued to the date of such payment on, the Loans made by it hereunder and all
other amounts (including without limitation, Reimbursement Obligations) owed to
it hereunder as of such date.

            Section 2.14 Indemnity.

                  (a The Borrower agrees to indemnify each Lender and to hold
each Lender harmless from any loss or expense which such Lender may sustain or
incur as a consequence of

                        (10 default by the Borrower in payment when due of any
                  portion of the principal amount of or interest on any
                  Eurodollar Loan,

                        (20 default by Borrower in making a borrowing of,
                  conversion into or continuation of Eurodollar Loans after
                  Borrower has given a notice requesting the same in accordance
                  with the provisions of this Agreement,

                        (30 default by Borrower in making any prepayment after
                  Borrower has given a notice thereof in accordance with the
                  provisions of this Agreement, or

                        (40 the making of a payment (other than scheduled
                  repayments) or a prepayment of Eurodollar Loans on a day which
                  is not the last day of an Interest Period with respect
                  thereto,

including, without limitation, in each case, any such loss or expense arising
from the reemployment of funds obtained by such Lender or from fees payable to
terminate the deposits from which such funds were obtained. If the Borrower
prepays all or any part of any advance which is accruing interest at a fixed
rate on other than the last day of the applicable interest period, the Borrower
shall also pay to the Lender, on demand therefor, the Cost of Prepayment. "Cost
of Prepayment" means an amount equal to the present value, if positive, of the
product of (a) the difference between (i) the yield, on the beginning date of
the applicable interest period minus (ii) the yield, on the prepayment date, of
a U.S. Treasury obligation with a maturity similar to the remaining maturity of
the applicable interest period, and (b) the principal amount to be prepaid, and
(c) the number of years, including fractional years from the prepayment date to
the end of the applicable interest period. The yield on any U.S. Treasury
obligation shall be determined by reference to Federal Reserve Statistical
Release H.15(519) "Selected Interest Rates." For purposes of making present
value calculations, the yield to maturity of a similar maturity U.S. Treasury
obligation on the prepayment date shall be deemed the discount rate. The Cost of
Prepayment shall also apply to any payments made after acceleration of the
maturity of any Note.

<PAGE>   39

                  (b For the purpose of calculation of all amounts payable to a
Lender under this subsection such Lender shall be deemed to have actually funded
its relevant Eurodollar Loan through the purchase of a deposit bearing interest
at the Eurodollar Rate in an amount equal to the amount of that Eurodollar Loan
and having a maturity comparable to the relevant Interest Period; provided,
however, that each Lender may fund each of its Eurodollar Loans in any manner it
sees fit, and the foregoing assumption shall be utilized only for the
calculation of amounts payable under this subsection.

                  (c The covenants in this Section 2.14 shall survive the
termination of this Agreement and the payment of the Notes and all other amounts
payable hereunder.

            Section 2.15 Letters of Credit.

                  (a By delivering to the Agent an Issuance Request on a
Business Day, prior to the Maturity Date and not less than three Business Days
prior to the requested date of issuance, Borrower may request that the Issuer
issue an irrevocable standby letter of credit in substantially the form of
Exhibit G, with such insertions with respect to required presentation of
documentation or certifications upon a draw as may be requested by the Borrower
and approved by the Issuer, or in such other form as may be requested by the
Borrower and approved by the Issuer and the Required Lenders (each a "Letter of
Credit"), in support of financial obligations of the Borrower incurred in the
ordinary course of business and which are described in such Issuance Request.
Upon receipt of each Issuance Request, the Agent shall promptly notify the
Lenders thereof. The stated amount of any Letter of Credit requested to be
issued pursuant to an Issuance Request shall be denominated in Dollars.

                  (b Each Letter of Credit shall by its terms: (i) be issued in
a stated amount which (A) is at least $20,000, and (B) when added to the Letter
of Credit Outstandings does not exceed (or would not exceed) the then Letter of
Credit Availability and (C) when added to all Revolving Credit Loans and Letter
of Credit Outstandings does not exceed the amount of the then Revolving Loan
Commitment; (ii) be stated to expire on a date (its "Stated Expiry Date") no
later than the earlier of 12 months from its date of issuance or March 30, 2001,
whichever occurs first; and (iii) on or prior to its Stated Expiry Date (A)
terminate immediately upon notice to the Issuer from the beneficiary thereunder
that all obligations covered thereby have been terminated, paid, or otherwise
satisfied in full, or (B) reduce in part immediately and to the extent the
beneficiary thereunder has notified the Issuer that the obligations covered
thereby have been paid or otherwise satisfied in part.

                                       34
<PAGE>   40

                  (c Subject to the terms and conditions of this Agreement, the
Issuer shall issue Letters of Credit in accordance with the Issuance Requests
made therefor. The Issuer will make available the original of each Letter of
Credit which it issues in accordance with the Issuance Request therefor to the
beneficiary thereof.

                  (d The Borrower agrees to pay to the Agent for the account of
the Issuer, with respect to each Letter of Credit, the following fees: (i) an
issuance fee of $150; (ii) $50 for each amendment to a Letter of Credit; (iii)
an amount equal to 1/4 of 1% ($200 minimum) of the amount of each draw under a
Letter of Credit; and (iv) a fronting fee equal to _ of 1% of the face amount of
such Letter of Credit. It is understood that the foregoing charges may be
changed by the Issuer from time to time. Any changes in such fees and charges
shall be binding on the Borrower on the date each change therein is established
by the Issuer. The fees payable pursuant to clause (i) and (iv) of this
paragraph (d) shall be paid upon issuance of the Letter of Credit. The fees
described in clause (ii) and (iii) shall be paid at the time of the relevant
amendment or draw, as the case may be.

                  (e To the extent of its Percentage, each Lender agrees to and
shall be deemed to have irrevocably purchased a participation in each Letter of
Credit on the date of issuance thereof. Each Lender shall make available to the
Issuer, regardless of whether any Default or Event of Default shall have
occurred and is continuing, an amount equal to its respective Percentage of each
drawing on each Letter of Credit in same day or immediately available funds not
later than 4:00 p.m. New York time on each Disbursement Date (as hereinafter
defined) for each such drawing provided such Lender has received notice pursuant
to Section 2.15(g) by 11:00 a.m. New York time; and by 10:00 a.m. on the next
Business Day if such notice is not received by 11:00 a.m. In the event that any
Lender fails to make available to the Issuer the amount of such Lender's
Percentage of any drawing on a Letter of Credit as provided herein, the Issuer
shall be entitled to recover such amount on demand from such Lender together
with interest at the daily average Federal Funds Rate for the first three
Business Days after the Disbursement Date and thereafter at the Base Rate.

                  (f The Agent shall distribute to each Lender that has paid all
amounts payable by it under this Section 2.15 with respect to any Letter of
Credit issued by Issuer such Lender's Percentage of all payments received by the
Agent from the Borrower in reimbursement of drawings honored by Issuer under
such Letter of Credit promptly after such payments are received.

                  (g The Issuer will notify the Borrower and the Agent promptly
of the presentment for payment of any Letter of

                                       35

Credit (on the date of presentment, if possible, and otherwise on the next
Business Day, it being agreed that such notice may be made by phone), together
with notice of the date (the "Disbursement Date") such payment shall be made and
the Agent will promptly notify the Lenders of such matters. Subject to the terms
and provisions of such Letter of Credit, the Issuer shall make such payment to
the beneficiary (or its designee) of such Letter of Credit. Prior to 3:00 p.m.
New York time on the Disbursement Date, the Borrower shall (by payment to the
Payment Office for distribution by the Agent) reimburse the Issuer for all
amounts which have been disbursed under such Letter of Credit. To the extent the
Issuer and the Lenders are not reimbursed in full in accordance with this
Section 2.15(g), the Reimbursement Obligation shall accrue interest at a rate
per annum equal to the Base Rate plus 4%, payable on demand.

                  (h The Borrower's obligation (a "Reimbursement Obligation")
under Section 2.15(g) to reimburse the Lenders with respect to each drawing
under each Letter of Credit (including interest thereon), and each Lender's
obligation to fund each drawing, shall be absolute and unconditional under any
and all circumstances and irrespective of any setoff, counterclaim or defense to
payment which any Person constituting the Borrower or any Lender may have or
have had against any Lender or any beneficiary of a Letter of Credit, including,
without limitation, any defense based upon the occurrence of any Default or
Event of Default, any draft, demand or certificate or other document presented
under a Letter of Credit proving to be forged, fraudulent, invalid or
insufficient, or any failure to apply or misapplication by the beneficiary of
the proceeds of any disbursement, or the legality, validity, form, regularity,
or enforceability of such Letter of Credit.

                  (i The Borrower assumes all risks of the acts, omissions or
misuse of any Letter of Credit by the beneficiary thereof. Except to the extent
of its own gross negligence or willful misconduct, the Issuer shall not be
responsible for:

                        (10 the form, validity, sufficiency, accuracy,
                  genuineness, or legal effect of any Letter of Credit or any
                  document submitted by any party in connection with the
                  application for and issuance of a Letter of Credit, even if it
                  should in fact prove to be in any or all respects invalid,
                  insufficient, inaccurate, fraudulent or forged;

                        (20 the form, validity, sufficiency, accuracy,

                  assigning or purporting to transfer or assign a Letter of
                  Credit or the rights or

                  transmission or delivery of any information or messages, by
                  mail, cable, telegraph, telex or otherwise;

                        (40 any loss or delay in the transmission or otherwise
                  of any document or draft required in order to make a
                  disbursement under a Letter of Credit or of the proceeds
                  thereof;

                        (50 errors in interpretation of technical terms;

                        (60 any misapplication by a beneficiary of the proceeds
                  of any disbursement under any Letter of Credit; and

                        (70 any consequences arising from causes beyond the
                  control of the Issuer including, without limitation, acts of
                  any Governmental Authority.

                  None of the foregoing shall affect, impair or prevent the
vesting of any of the rights or powers granted to the Issuer hereunder.

                  (j In addition to amounts payable as elsewhere provided in
this Section 2.15, the Borrower hereby agrees to protect, indemnify, pay and
save the Issuer harmless from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees) which the Issuer may incur or be subject to as a consequence,
direct or indirect, of (i) the issuance of the Letters of Credit, other than as
a result of the gross negligence or wilful misconduct of the Issuer as
determined by a court of competent jurisdiction, or (ii) the failure of the
Issuer to honor a drawing under any Letter of Credit as a result of any act or
omission, whether rightful or wrongful, of any present or future de jure or de
facto Governmental Authority.

                  (k KeyBank or any successor Issuer may resign as such at any
time upon at least ten days' prior notice to the Borrower, the Agent and all
Lenders. If the Issuer at any time shall resign, KTI may appoint another Lender
as a successor Issuer provided such appointment is accepted by such Lender. Upon
the acceptance of any appointment as Issuer by a successor Issuer, such
successor Issuer shall thereupon become the Issuer hereunder and the resigning
or removed Issuer shall (i) be discharged from its duties and obligations as
such under this

and unexpired Letters of Credit issued by it and (ii) entitled to the continued
benefit of this Section 2.15 with respect to all Letters of Credit issued and
actions taken by it prior to its resignation.

Loans shall be used first to repay all amounts outstanding under the Existing
Loan Agreement and all outstanding Indebtedness of KTI Recycling of New England,
Inc. (formerly I. Zaitlin & Sons) owing to KeyBank. After repayment of all such
amounts, proceeds of Revolving Credit Loans may be used to finance working
capital needs of the Borrower (including, without limitation, payment of
Reimbursement Obligations) and for general corporate purposes including, without
limitation, the financing of Acquisitions permitted by the terms hereof.

            ARTICLE 3 REPRESENTATIONS AND WARRANTIES

            To induce the Agent and the Lenders to enter into this Agreement and
to make the Loans, the Borrower hereby represents and warrants to the Agent and
the Lenders that as of the Effective Date:

            Section 3.1 Financial Condition.

                  (a The consolidated balance sheets of KTI and its consolidated
Subsidiaries as at December 31, 1997 and March 31, 1998 and the related
consolidated statements of income and of cash flows for the fiscal period ended
on each such date, copies of which have heretofore been furnished to the Agent
and the Lenders, present fairly in all material respects the consolidated
financial condition of KTI and its consolidated Subsidiaries as at such dates,
and the consolidated results of their operations and their consolidated cash
flows for the fiscal year and quarter, as the case may be, then ended.

                  (b All such financial statements, including the related
schedules, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by such accountants and as
disclosed therein).

                  (c Neither KTI nor any of its consolidated Subsidiaries had,
at the date of the most recent balance sheet delivered to the Agent pursuant to
Section 5.1 hereof, any material Contingent Obligation, material contingent
liability (other than with respect to performance bond obligations entered into
the ordinary course of business) or material liability for taxes, or any
material long-term lease or material unusual forward or long-term commitment,
including, without limitation, any interest rate or foreign currency swap or
exchange

                                       38

transaction or other financial derivative, except as reflected in the foregoing
statements or in the notes thereto or would not reasonably be expected to have a
Material Adverse Effect.

                  (d During the period from December 31, 1997, to and including
the Effective Date hereof there has been no sale, transfer or other disposition
by KTI or any of its consolidated Subsidiaries of any material part of its
business or property (other than in the ordinary course of business) and no
purchase or other acquisition of any business or property (including any Capital
Stock of any other Person, in any case, other than in the ordinary course of
business) material in relation to the consolidated financial condition of KTI
and its consolidated Subsidiaries at December 31, 1997 except the Acquisition of
all of the issued and outstanding stock of all classes of Multitrade Group,
Inc., Vel-A-Tran Recycling Inc. and Total Waste Management Corporation.

            Section 3.2 No Material Adverse Change. Since December 31, 1997,
there has been no development or event which has had or could reasonably be
expected to have a Material Adverse Effect.

            Section 3.3 Corporate Existence; Compliance with Law. Each of KTI
and its Subsidiaries (other than Inactive Subsidiaries)(a) is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization, (b has the power and authority, and the legal right, to own and

the business in which it is currently engaged, (c) is duly qualified as a
foreign Person and in good standing under the laws of each jurisdiction where
its ownership, lease or operation of property or the conduct of its business
requires such qualification except where the failure to so qualify or be in good
standing therewith would not have a Material Adverse Effect and (d) is in
compliance with all Requirements of Law except where the failure to comply
therewith would not, in the aggregate, have a Material Adverse Effect. Without
limiting the generality of the foregoing, KTI and each of its Subsidiaries has
obtained and currently maintains all necessary and material licenses, building
permits, environmental permits, utility permits, land use permits and any other
permits, approvals or licenses and governmental authorizations from all
applicable federal, state, district and local Persons and other Governmental

Subsidiaries has all necessary and material licenses, permits and other consents
from Governmental Authorities otherwise

                                       39

required for the conduct of their respective business; provided that, in the
case of Total Waste Management Corporation, certain of its permits are held on a
temporary or interim basis as described in the letter of Sheehan, Phinney, Bass
& Green, dated July 1, 1998 and addressed to Robert Wetzel, Esq. at KTI (a copy

                                       40

of which has been delivered to the Agent).  KTI Environmental Group, Inc.,

merger between KTI Environmental Group, Inc. and Kuhr Technologies, Inc.

            Section 3.4 Corporate Power; Authorization; Enforceable Obligations.

                  (a Each Person constituting the Borrower has the power and
authority, and the legal right, to make, deliver and perform this Agreement, the
Notes and each other Loan Document to which it is a party and to borrow
hereunder and has taken all necessary corporate or partnership action to
authorize the borrowings on the terms and conditions of this Agreement, the
Notes and each other Loan Document to which it is a party and to authorize the
execution, delivery and performance of this Agreement, the Notes and each other
Loan Document to which it is a party.

                  (b Except for consents, authorizations, approvals, notices and
filings described on Schedule III, all of which have been obtained, made or
waived, no consent or authorization of, approval by, notice to, filing with or
other act by or in respect of, any Governmental Authority or any other Person is
required in connection with the borrowings hereunder or with the execution,
delivery, performance, validity or enforceability of this Agreement or the Notes
or any other Loan Document.

                  (c This Agreement has been, and each Note and each other Loan
Document to which it is a party will be, duly executed and delivered on behalf
of each Person constituting the Borrower.

                  (d This Agreement constitutes, and each Note and each other
Loan Document when executed and delivered will constitute, a legal, valid and
binding obligation of each Person constituting the Borrower enforceable against
each such Person in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally and by
general equitable principles (whether enforcement is sought by proceedings in
equity or at law).

            Section 3.5 No Legal Bar. The execution, delivery and performance of
this Agreement and the Notes, the borrowings hereunder and the use of the
proceeds thereof will not violate any Requirement of Law or Contractual
Obligation of any Person constituting the Borrower or of any of their respective
Subsidiaries and, except as required by the Loan Documents, will

                                       41
<PAGE>   47

not result in, or require, the creation or imposition of any Lien on any of its
or their respective properties or revenues pursuant to any such Requirement of
Law or Contractual Obligation.

            Section 3.6 No Material Litigation. Except as set forth on Schedule
IV, no litigation, investigation or proceeding of or before any arbitrator or
Governmental Authority is pending or, to the knowledge of the any Person
constituting the Borrower, threatened by or against any Person constituting the
Borrower or any of their respective Subsidiaries or against any of its or their
respective properties or revenues (a) with respect to this Agreement or the
Notes or any of the transactions contemplated hereby, or (b) which if adversely
determined would have a Material Adverse Effect.

            Section 3.7 No Default. No Person constituting the Borrower nor any
of their respective Subsidiaries is in default under or with respect to any of
their respective Contractual Obligations in any respect which would reasonably
be expected to have a Material Adverse Effect. No Default or Event of Default
has occurred and is continuing.

            Section 3.8 Ownership of Property; Liens. Each Person constituting
the Borrower and their respective Subsidiaries has good record and marketable
title in fee simple to, or a valid leasehold interest in, all its real property
(and no part thereof is subject to a lease, concession or like agreement between
KTI or any Subsidiary Borrower, as lessor or owner, and a third party, as
lessee), and good title to, or a valid leasehold interest in, all its other
property, and none of such property is subject to any Lien except as permitted
by Section 6.2. All such property is set forth on Schedule II.

            Section 3.9 Intellectual Property. Each Person constituting the
Borrower and each of their respective Subsidiaries owns, or is licensed to use,
all trademarks, tradenames, copyrights, patents, technology, know-how and
processes necessary for the conduct of its business as currently conducted
(collectively, the "Intellectual Property") except where the failure to own or
license any such Intellectual Property would not have a Material Adverse Effect.
Except as set forth on Schedule V, no claim has been asserted in writing or is
pending by any Person challenging or questioning the use of any such
Intellectual Property or the validity or effectiveness of any such Intellectual
Property which would have a Material Adverse Effect, nor does any Person
constituting the Borrower know of any valid basis for any such claim which, if
asserted, would have a Material Adverse Effect. To the best of the knowledge of
the Borrower, the use of such Intellectual Property by each Person constituting
the Borrower and their respective Subsidiaries does not infringe the rights of
any Person.

                                       42
<PAGE>   48

            Section 3.10 No Burdensome Restrictions. No Requirement of Law or

(other than any the amount or validity of which are currently being contested in
good faith by appropriate proceedings and with respect to which reserves in
conformity with GAAP have been provided on the books of such Person constituting
the Borrower or its respective Subsidiaries, as the case may be); no tax Lien
has been filed, and, to the knowledge of such Person, no claim is being
asserted, with respect to any such tax, fee or other charge in any case which
would have a Material Adverse Effect.

            Section 3.12 Federal Regulations. No part of the proceeds of any
Loans will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U of the Board
as now and from time to time hereafter in effect or for any purpose which
violates the provisions of any Regulations of the Board. If requested by any
Lender at any time, each Person constituting the Borrower will furnish to such
Lender a statement in conformity with the requirements of FR Form U-1 referred
to in Regulation U.

            Section 3.13 Investment Company Act; Public Utility Holding Company
Act; Other Regulations. No Person constituting the Borrower is (a) an

within the meaning of the Investment Company Act of 1940, as amended, or (b) a
"holding company" as defined in, or otherwise subject to regulation under, the
Public Utility Holding Company Act of 1935. No Person constituting the Borrower
is subject to regulation under any federal or state statute or regulation which

                                       43
<PAGE>   49

Subsidiary is subject to a Lien in favor of any Person other than the Agent
pursuant to the Loan Documents.

            Section 3.15 Employee Grievances. Except as set forth on Schedule
VII hereof, as of the Effective Date no Person constituting the Borrower nor any
of their Subsidiaries is a party to any collective bargaining agreement or, to
the best knowledge of such Person, subject to any current effort to organize,
and there are no actions or proceedings pending or, to the best of the knowledge
of such Person, threatened against it or its Subsidiaries, by or on behalf of,
or with, its employees, other than employee grievances arising in the ordinary
course of business which are not, in the aggregate, material.

            Section 3.16 ERISA.

                  (a Except as set forth in Schedule VIII hereof, as of the
Effective Date no Person constituting the Borrower nor any of their Subsidiaries
have any Plan (including without limitation any Multiemployer Plan) or have made
or make any payments to any Plan.

                  (b Each Person constituting the Borrower and each Subsidiary
of such Person is and has at all times been in substantial compliance with all
applicable provisions of ERISA, except where a failure to be in such compliance
would not have a Material Adverse Effect.

                  (c No Person constituting the Borrower has engaged in a
transaction in connection with which such Person or any ERISA Affiliate could be
subject to a material liability for either a civil penalty assessed pursuant to
Section 502(i) of ERISA or a tax imposed by Section 4975 of the Code.

                  (d There has been no termination of a Plan or trust created
under any Plan that would give rise to a material liability to the PBGC on the
part of any Person constituting the Borrower or any ERISA Affiliate. No material
liability to the PBGC has been or is expected to be incurred with respect to any
Plan by any Person constituting the Borrower or any ERISA Affiliate. The PBGC
has not instituted proceedings to terminate any Plan. There exists no condition
or set of circumstances which presents a material risk of termination or partial
termination of any Plan by the PBGC. Each Person constituting the Borrower and
each ERISA Affiliate have paid all premiums to the PBGC when due.

                  (e Full payment has been made of all amounts which are
required under the terms of each Plan to have been paid as contributions to such
Plan as of the last day of the most recent fiscal year of such Plan ended on or
before the date of

                                       44
<PAGE>   50

this Agreement, and no accumulated funding deficiency (as defined in Section 302
of ERISA and Section 412 of the Code), whether or not waived, exists with
respect to any Plan. No Person constituting the Borrower nor any ERISA Affiliate
has failed to make a required installment under Section 412(m) of the Code or
any other payment required under Section 412 of the Code on or before the due
date.

                  (f The value of the benefit liabilities (as defined in Section
4001(a)(16) of ERISA) of each Plan (based on the actuarial assumptions contained
in Title IV of ERISA) does not exceed the fair market value of the assets of
such Plan. No Person constituting the Borrower nor any ERISA Affiliate is
required to provide security to a Plan under Section 401(a)(29) of the Code.

                  (g No Person constituting the Borrower nor any ERISA Affiliate
has made a complete or partial withdrawal from a Multiemployer Plan. To the best
knowledge of each Person constituting the Borrower the liability to which such
Person or any ERISA Affiliate would become subject under ERISA if such Person
and all ERISA Affiliates were to withdraw completely from all Multiemployer
Plans as of the most recent valuation date, together with any secondary
liability for withdrawal liability such Person and any ERISA Affiliate may have
as of the date hereof, would not have a Material Adverse Effect. To the best
knowledge of each Person constituting the Borrower no such Multiemployer Plan is
in reorganization (as such term is defined in Section 4241 of ERISA) or is
insolvent (as such term is defined in Section 4245 of ERISA).

            Section 3.17 Solvency. KTI and each Subsidiary Borrower is Solvent.

            Section 3.18 Year 2000 Compliance. Each Person constituting the
Borrower has conducted a comprehensive review and assessment of its computer
applications with respect to the "year 2000 problem" (that is, the risk that
computer applications may not be able to properly perform data-sensitive
functions after December 31, 1999) and, based on that review, Borrower
represents that the year 2000 problem will not have a Material Adverse Effect.
To the best of Borrower's knowledge, no failure to address the year 2000 problem
on the part of any supplier, vendor or other Person with whom any Person
constituting the Borrower does business with have a Material Adverse Effect.

            Section 3.19 Disclosure. There is no fact known to the Borrower
which materially adversely affects or in the future (so far as the Borrower can
now foresee) materially adversely affect the business, property, assets or
financial condition of KTI or any of its Subsidiaries which has not been set
forth in this

                                       45

Agreement or in the other documents, certificates and statements furnished to
the Agent or the Lenders by or on behalf of the Borrower prior to the date
hereof in connection with the transactions contemplated hereby.

<PAGE>   72

            Section 8.1 Actions. Each Lender authorizes the Agent to act on
behalf of such Lender under this Agreement, the other Loan Documents and any
other related instruments and, in the absence of other written instructions from
the Lenders received from time to time by the Agent (with respect to which the
Agent agrees that it will, subject to the provisions of this Section 8.1, comply
in good faith except as otherwise advised by counsel), to exercise such powers
hereunder and thereunder as are specifically delegated to or required of the
Agent by the terms hereof and thereof, together with such powers as may be
reasonably incidental thereto. Each Lender agrees (which agreement shall survive
any termination of this Agreement) to indemnify the Agent, pro rata according to
such Lender's Percentage, from and against any and all liabilities, obligations,
damages, penalties, actions, judgements, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may at any time be imposed on, incurred
by, or asserted against the Agent in any way relating to or arising out of this
Agreement, the Revolving Credit Notes, the Letters of Credit, any of the other
Loan Documents and any other related instruments, including, without limitation,
the reimbursement of the Agent for all reasonable out-of-pocket expenses
(including, without limitation, syndication costs and attorneys' fees) incurred
by the Agent hereunder or in connection herewith or in enforcing the obligations
of the Borrower or any Lender under this Agreement, under any of the other Loan
Documents or any other related instruments, in all cases as to which the Agent
is not reimbursed by the Borrower; provided that no Lender shall be liable for
the payment of any portion of such liabilities, obligations, damages, penalties,
actions, judgements, suits, costs, expenses or disbursements determined by a
court of competent jurisdiction in a final proceeding to have resulted solely
from the Agent's gross negligence or willful misconduct. The Agent shall not be
required to take any action hereunder or under any other related instruments, or
to prosecute or defend any suit in respect of this Agreement or any such
instrument, unless indemnified to its satisfaction by the Lenders against costs,
liability, and expense. If any indemnity in favor of the Agent shall become
impaired, it may call for additional indemnity and cease to do the acts
indemnified against until such additional indemnity is given. The Agent may
delegate its duties hereunder to affiliates, agents or attorneys-in-fact
selected in good faith by the Agent. Each Lender's obligation to indemnify the
Agent as set forth above shall be unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment which such
Lender may have or have had against the Agent, any other Lender, the Borrower,
any Subsidiary or any other Person.

            Section 8.2 Exculpation. The Agent shall have no duties or
responsibilities except those expressly set forth in


                                       67

this Agreement. Neither the Agent nor any of its directors, officers, employees,
or agents (collectively, the "Related Parties") shall be liable to any Lender
for any action taken or omitted to be taken by it under this Agreement, the
other Loan Documents or any other related instrument, or in connection herewith
or therewith, except for its own willful misconduct or gross negligence, nor
shall the Agent or any Related Parties be responsible for any recitals or
representations or warranties herein or therein, or for the effectiveness,
enforceability, validity or due execution of this Agreement, the other Loan
Documents or any other related instruments, nor shall the Agent or any Related
Parties be obligated to make any inquiry respecting the performance by the
Borrower of its obligations hereunder or thereunder. The Agent shall be entitled
to rely upon advice of counsel concerning legal matters and upon any notice,
consent, certificate, statement or writing which it believes to be genuine and
to have been presented by a proper Person. The Agent may at any time request
instructions from the Lenders with respect to any actions or approvals which, by
the terms of this Agreement, the Agent is permitted or required to take or
grant, and the Agent shall be absolutely entitled to refrain from taking any
action or to withhold any approval and shall not be under any liability
whatsoever to any Person for refraining from taking any action or withholding
any approval under this Agreement or any of the other Loan Documents until it
has received instructions from the Required Lenders. No Lender shall have any
right of action whatsoever against the Agent as a result of the Agent acting or
refraining from acting hereunder or under any of the other Loan Documents in
accordance with instructions from the (i) Required Lenders, or (ii) all of the
Lenders to the extent required hereunder.

            Section 8.3 Successor. The Agent may resign as such at any time upon
at least ten days' prior notice to the Borrower and all Lenders, and the Agent
may be removed at any time by written notice from the Required Lenders. If the
Agent at any time shall resign or be removed, the Required Lenders may appoint
another Lender as a successor Agent provided such appointment is consented to by
KTI (which consent shall not be unreasonably withheld). If the Required Lenders
do not make such appointment within thirty days, the resigning or removed Agent
shall appoint a new Agent from among the Lenders or, if no Lender accepts such
appointment, from among commercial banking institutions or trust institutions
generally; provided such successor agent shall be a domestic commercial bank
having a combined capital and surplus in excess of $500,000,000. Upon the
acceptance of any appointment as Agent by a successor Agent, such successor
Agent shall thereupon become the Agent hereunder and shall be entitled to
receive from the prior Agent such documents of transfer and assignment as such
successor Agent may reasonably request, and the resigning or removed Agent shall
(i) be discharged from its


                                       68
<PAGE>   74

duties and obligations under this Agreement and the other related instruments
and (ii) entitled to the continued benefit of this Article 8 with respect to all
actions taken by it prior to its removal or resignation.

            Section 8.4 Credit Decisions. Each Lender represents and
acknowledges to the Agent that it has, independently of the Agent and each other
Lender, and based on the financial information referred to in this Agreement and
the other Loan Documents and such other documents, information and
investigations as it has deemed appropriate, made its own credit decision to
enter into this Agreement. Each Lender also acknowledges that it will,
independently of the Agent and each Lender, and based on such documents,
information and investigations as it shall deem appropriate at any time,
continue to make its own credit decisions as to exercising or not exercising
from time to time any rights and privileges available to it under this
Agreement, the Loan Documents or any other related instruments.

            Section 8.5 Notices, etc. from Agent. The Agent shall give prompt
notice to each Lender of each notice or request given to the Agent by the
Borrower or by the Agent to the Borrower pursuant to the terms of this
Agreement. The Agent will promptly distribute to each Lender each instrument
received for its account and copies of all other communications received by the
Agent from the Borrower for distribution to the Lenders by the Agent in
accordance with the terms of this Agreement.

            Section 8.6 Security Documents. Each Lender hereby authorizes the
Agent to enter into the Security Documents and to take all action contemplated
thereby. Each Lender agrees that no Lender shall have any right individually to
seek to realize upon the collateral granted for the benefit of the Lenders
pursuant to any of the Security Documents, it being understood and agreed that
such rights and remedies may be exercised by the Agent for the benefit of the
Agent and the Lenders upon the terms of the Security Documents.

            Section 9.1 Purchasing Lender. (a) Each Lender, in the ordinary
course of its commercial banking business and in accordance with applicable law,
at any time may sell, assign and delegate to any Affiliate of such Lender
and/or, with the consent of the Agent and KTI (which in each case shall not be
unreasonably withheld or delayed and provided that KeyBank shall not require
KTI's consent with respect to any Purchasing Lender previously acknowledged by
KTI to KeyBank to be acceptable to it), to one or more additional banks or
financial institutions (each, a "Purchasing Lender"), subject to minimum holding
level for each Lender of $10,000,000, such Lender's rights and obligations under
this Agreement, the Notes and the other Loan Documents (provided, that any such
sale, assignment and delegation shall be made with respect to each Loan,
participation in Letter of Credit Outstandings and Commitment of such Lender
hereunder) pursuant to an agreement ("Assignment and Acceptance"), executed by
the Purchasing Lender, and such Lender. Such Assignment and Acceptance shall
specify an effective date which is not less than five Business Days after the
date of execution thereof. Upon such execution, delivery, and acceptance, from
and after the effective date determined pursuant to such Assignment and
Acceptance and payment by the assigning Lender of a $2,500 administration fee to
the Agent with respect to each Purchasing Lender party to such Assignment and
Acceptance, (A) the Purchasing Lender thereunder shall be a party hereto and, to
the extent of the Commitments assigned and Loans sold pursuant to such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a Commitment as set forth therein (including, without limitation, (x) the
right to approve or disapprove of actions which, in accordance with the terms
hereof, require the approval of the Required Lenders or all Lenders, as the case
may be, and (y) the obligation to make Loans and purchase participations in each
Letter of Credit), and (B) the assigning Lender thereunder shall, to the extent
of the Commitments assigned pursuant to such Assignment and Acceptance, be
released from its obligations under this Agreement (and, in the case of an
Assignment and Acceptance covering all or the remaining portion of an assigning
Lender's rights and obligations under this Agreement, such assigning Lender
shall cease to be a party hereto). Such Assignment and Acceptance shall be
deemed to amend this Agreement to the extent, and only to the extent, necessary
to reflect the addition of such Purchasing Lender as a Lender and the resulting
adjustment of Commitments arising from the purchase by such Purchasing Lender of
all or a portion of the rights and obligations of such assigning Lender under
this Agreement and the Notes. On or prior to the effective date determined
pursuant to such Assignment and Acceptance, the Borrower, at its own expense,
shall execute and deliver to the assigning Lender and Purchasing Lender in
exchange for the surrendered Revolving Credit Note, a new Revolving Credit Note
to the order of such Purchasing Lender in an amount equal to the


                                       70
<PAGE>   76

Commitment assumed by it pursuant to such Assignment and Acceptance and, if the
assigning Lender has retained a Commitment hereunder, a new Revolving Credit
Note to the order of the assigning Lender in an amount equal to the Commitment
retained by it hereunder. Such new Note or Notes shall be dated the Closing Date
and otherwise shall be in the form of the Note or Notes replaced thereby. The
Note or Notes surrendered by the assigning Lender shall be returned to the
Borrower marked "replaced." The assigning Lender shall provide the Agent with a
copy of each Assignment and Acceptance.

                  (b) If, pursuant to this Agreement, any interest in this
Agreement or any other Loan Documents is assigned to any transferee which is
organized under the laws of any jurisdiction other than the United States or any
State thereof, the transferor Lender shall cause such transferee, concurrently
with the effectiveness of such transfer, (i) to represent to the transferor
Lender (for the benefit of the transferor Lender, the Agent and the Borrower)
that under applicable law and treaties no taxes will be required to be withheld
by the Agent, the Borrower or the transferor Lender with respect to any payments
to be made to such transferee in respect of the Loans, (ii) to furnish to the
transferor Lender, the Agent and the Borrower either Form 4224 or Form 1001
(Ownership Exemption or Reduced Rate Certificate) or any successor forms
(wherein such transferee claims entitlement to complete exemption from U.S.
federal withholding tax on all interest payments hereunder) and (iii) to agree
(for the benefit of the transferor Lender, the Agent and the Borrower) to
provide (so long as it may lawfully do so) the transferor Lender, the Agent and
the Borrower a new Form 4224 or Form 1001 or any successor forms upon the
expiration or obsolescence of any previously delivered form and comparable
statements in accordance with applicable U.S. laws and regulations and
amendments duly executed and completed by such transferee, and to comply from
time to time with all applicable U.S. laws and regulations with regard to such
withholding tax exemption. Any foreign lender that fails to comply may not claim
any recovery from Borrower for withholding taxes.

            Section 9.2 Participations. The Lenders may grant participations in
any part of the Loans or Revolving Credit Notes or their obligations with
respect to Letters of Credit to any of their affiliates or to any other
commercial bank or other financial institution; provided, however, that (1) such
Lender's obligations under this Agreement shall remain unchanged, (2) such
selling Lender shall remain solely responsible for the performance of such
obligations and (3) the Borrower, the Agent and the other Lenders shall continue
to deal solely and directly with such selling Lender in connection with all
rights and obligations under this Agreement. Any agreement pursuant to which a
selling Lender may grant a participation may provide that


                                       71
<PAGE>   77

such Lender will not agree to any amendment or waiver expressed in clause A
through D or G of Section 10.1(a) of this Agreement without the consent of the
participant, but shall not require any Lender to take or omit to take any other
action hereunder.

            Section 9.3 Disclosure of Information. Each Person constituting the
Borrower authorizes the Lenders to disclose to any Purchasing Lender, any
prospective Purchasing Lender and any participant or prospective participant any
and all information relating to each Person constituting the Borrower and its
Affiliates which has been furnished to the Agent and the Lenders by or on behalf
of each Person constituting the Borrower; provided that any such recipient
agrees to keep any information relating to any Person constituting the Borrower
received hereunder confidential except as may be required by any Requirement of
Law.

            Section 9.4 Pledges to Federal Reserve Bank. Nothing herein shall
prohibit any Lender from pledging or assigning any Note to any Federal Reserve
Bank in accordance with applicable law.

            Section 10.1 Amendments and Waivers. (a) No amendment or waiver of
any provision of this Agreement, or any of the other Loan Documents, nor consent
to any departure by the Borrower therefrom, shall in any event be effective
unless the same shall be in writing and signed by the Required Lenders, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given; provided, however, that no amendment,
waiver or consent, unless in writing and signed by all the Lenders, shall do any
of the following: (A) waive any of the conditions specified in Section 4.1
(though the Agent alone may defer the fulfillment of such conditions until the
date of the applicable borrowing), (B) increase the amount or extend the term of
the Commitments of the Lenders or subject the Lenders to any additional
obligations, (C) reduce the principal of, or interest on, the Loans, the
Reimbursement Obligations or any of the Notes, or reduce any fees payable
hereunder, (D) postpone any date fixed for any payment in respect of principal
of, or interest on, the Loans, the Reimbursement Obligations or any of the
Notes, as the case may be, or fees payable hereunder, (E) change any of the
components which shall be required for the Lenders or any Lender to take any
action hereunder, (i.e., the Percentage of the Commitments, or the aggregate
unpaid principal amount of the Loans, or the number of Lenders), (F) amend or
terminate any Security Document, or (G) amend this Section 10.1; and provided,
further, that no amendment, waiver or consent shall, unless in writing and
signed by the Agent in addition to the Lenders hereinabove required to take such
action, affect the rights or duties of the Agent under this Agreement. Without
derogating from the foregoing, no amendment to this Agreement shall be effective
unless signed by each Person constituting the Borrower.

                  (b) The liability of each Person constituting the Borrower
hereunder shall be absolute and unconditional irrespective of:

                        (1) any change in the time, manner, or place of payment
or in any other term of, or any other amendment or waiver of, or any consent to
departure from any of the Loan Agreement, any of the Loan Documents or any
Obligations;

                        (2) any change in the name, capital stock, Certificate
of Incorporation or by-laws, as the case may be, of any Person constituting the
Borrower;

                        (3) the insolvency of, or the voluntary or involuntary
bankruptcy, assignment for the benefit of creditors, reorganization or other
similar proceedings affecting any Person constituting the Borrower or any of
their respective assets; or


                                       73
<PAGE>   79

                        (4) any other circumstance or claim which might
otherwise constitute a defense available to, or a discharge of, any Person
constituting the Borrower in respect of the Obligations.

                  (c) No payment made by any Person constituting the Borrower,
or received or collected by the Agent or any of the Lenders, from any Person
constituting the Borrower by virtue of any action or proceeding or set-off or
application at any time in reduction of or in payment of the Obligations shall
be deemed to modify, release or otherwise affect the liability of any Person
constituting the Borrower under the Loan Documents. Notwithstanding any such
payments received or collected by the Agent or any of the Lenders in connection
with the Obligations, each Person constituting the Borrower shall remain liable
for the Obligations until all Obligations are paid in full. The joint and
several obligation of each Person constituting the Borrower shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Obligations is rescinded or must otherwise be returned by the Agent
or the Lenders upon the insolvency, bankruptcy or reorganization of any Person
constituting the Borrower or otherwise, all as though such payment had not been
made.

                  (d) The obligations and liabilities of each Person
constituting the Borrower hereunder shall not be released, discharged, limited
or in any way affected by anything done, suffered or permitted by the Agent or
Lenders in connection with any monies or credit advanced by the Agent or Lenders
to any Person constituting the Borrower or any security therefor, including,
without limitation, any loss of, or in respect of, any security received by the
Agent or any of the Lenders from any Person constituting the Borrower. It is
agreed that the Lenders and/or the Agent, without releasing, discharging,
limiting or otherwise affecting in whole or in part the obligations and
liabilities of any Person constituting the Borrower hereunder, may, without
limiting the generality of the foregoing:

                  (A) grant time, renewals, extensions, indulgences, releases
            and discharges to any Person constituting the Borrower;

                  (B) take or abstain from taking security or collateral for the
            Obligations or from perfecting security or collateral for the
            Obligations;

                  (C) release, discharge, compromise or otherwise deal with
            (with or without consideration) any and all collateral, mortgages,
            indemnities, guaranties or other security given by any Person
            constituting the Borrower with respect to the Obligations;

                  (D) accept compromises from any Person constituting the
            Borrower;

                  (E) after an Event of Default, apply all monies at any time
            received from any Person constituting the Borrower or from any
            guaranties, indemnities or any collateral upon such part of the
            Obligations as the Lenders and/or Agent may see fit or change any
            such application in whole or in part from time to time as the Agent
            or such Lenders may see fit; or

                  (F) otherwise deal with each Person constituting the Borrower
            and all other Persons and collateral as the Lenders and/or Agent may
            see fit;

                  (e) neither the Agent nor any of the Lenders shall be bound or
            obligated to exhaust recourse against any Person constituting the
            Borrower or other Persons or any security, guarantee, indemnity,
            mortgage or collateral it may hold or take any other action before
            being entitled to payment from each Person constituting the Borrower
            hereunder and each Person constituting the Borrower hereby waives
            any requirement that would otherwise compel the Agent or the Lenders
            to do any of the foregoing.

Lenders, the Agent (on behalf of the Lenders) shall have no obligation to

                  (a) No failure to exercise and no delay in exercising, on the

further exercise thereof or the exercise of any other right, remedy, power or

<PAGE>   84

                  (a) In addition to any rights and remedies of the Agent and
Lenders provided by law, each Lender shall have the right, without prior notice
to any Person constituting the Borrower, any such notice being expressly waived
by each Person constituting the Borrower to the extent permitted by applicable
law, upon any amount becoming due and payable by any Person constituting the
Borrower hereunder or under the Notes or the other Loan Documents (whether at
the stated maturity, by acceleration or otherwise) to set-off and appropriate
and apply against such amount any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender or any branch or agency of such Lender to or for the credit
or the account of any Person constituting the Borrower. Each Lender agrees
promptly to notify the Borrower and Agent after any such set-off and application
made by such Lender, provided that the failure to give such notice shall not
affect the validity of such set-off and application.

                  (b) Each of the Lenders agree among themselves that with
respect to all amounts received by them which are applicable to the payment or
satisfaction of all or part of the Loans or Reimbursement Obligations, interest
thereon, any fees or any other amount payable hereunder or under the other Loan
Documents, equitable adjustment will be made so that, in effect, all such
amounts will be shared among the Lenders in proportion to their respective
Percentages, whether received by voluntary payment, by the exercise of the right
of setoff or banker's lien, by counterclaim or by the enforcement of their
rights hereunder or under the other Loan Documents.

                  (c) If any Lender shall, through the exercise of any right of
counterclaim, setoff, banker's lien or otherwise, receive payment or reduction
of a proportion of the aggregate amount of the Loans or interest thereon due to
such Lender, or any other amount payable hereunder, as the case may be, which is
greater than the proportion received by any other Lender or Lenders in respect
to the aggregate amount of any Loan or Reimbursement Obligation and interest
thereon due such Lender, or with respect to any other amount payable hereunder,
that Lender receiving such proportionately greater payment shall notify the
other Lenders and the Agent of such receipt and purchase participations (which
it shall be deemed to have done simultaneously upon the receipt of such excess
payment) in the Loans and Reimbursement Obligations held by the other Lender or
Lenders so that all such recoveries of principal and interest with respect to
the Loans shall be proportionate to each Lender's respective Percentage;
provided that if all or part of such proportionately greater payment received by
such purchasing 


                                       79
<PAGE>   85

Lender is thereafter recovered from such Lender, those purchases shall be
rescinded and the purchase prices paid for such participations shall be returned
to the purchasing Lender to the extent of such recovery, but without interest.

                  (d) The Borrower expressly consents to the arrangements
described in this Section 10.7.

            Section 10.8 Usury Laws. This Agreement and the other Loan Documents
are each subject to the express condition that at no time shall Borrower be
obligated or required to pay interest on the principal balance due under any of
the Loan Documents at a rate which could subject the obligee under any Loan
Documents to either civil or criminal liability as a result of being in excess
of the maximum interest rate which Borrower is permitted by the law of the
jurisdiction stated to govern such Contractual Obligation to contract or agree
to pay. If by the terms of this Loan Agreement or any of the Loan Documents, the
Borrower is at any time required or obligated to pay interest on any amounts due
on any of the Loan Documents at a rate in excess of such maximum rate, the rate
of interest under such Loan Document shall be deemed to be immediately reduced
to such maximum rate and the interest payable shall be computed at such maximum
rate (provided, however, that the total amount of such interest shall be
amortized, prorated and allocated over the period commencing from the date
hereof until payment in full of all of the Obligations). Notwithstanding the
foregoing, it is agreed the fees and interest to be paid pursuant hereto were
set with reference to New York General Obligations Law Section 5501.6.b.

            Section 10.9 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts,
and all of said counterparts taken together shall be deemed to constitute one
and the same instrument.

            Section 10.10 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

            Section 10.11 Integration. This Agreement represents the agreement
of the Borrower, the Agent and the Lenders with respect to the subject matter
hereof, and there are no promises, undertakings, representations or warranties
by the Agent or any Lender relative to subject matter hereof not expressly set
forth or referred to herein or in the other Loan Documents, except as 


                                       80

between the Agent and KTI, the Fee Letter and those provisions of the Commitment
Letter dated May 21, 1998 relating to syndication which are stated to survive
the execution of the Loan Documents.

            Section 10.12 Governing Law. This Agreement and the Notes and the
rights and obligations of the parties under this Agreement and the Notes shall
be governed by, and construed and interpreted in accordance with, the law of the
State of New York. This choice of law is made pursuant to General Obligations
Law Section 5-1401.

            Section 10.13 Submission To Jurisdiction; Waivers. Each Person
constituting the Borrower hereby irrevocably and unconditionally:

                  (a) submits for itself and its property in any legal action or
proceeding relating to or arising out of this Agreement and the other Loan
Documents to which it is a party, or the conduct of any party with respect
thereto, or for recognition and enforcement of any judgement in respect thereof,
to the nonexclusive jurisdiction of any court of the State of New York or any
federal court sitting in the City and State of New York;

                  (b) consents that any such action or proceeding may be brought
in such courts and waives to the fullest extent permitted by law any objection
that it may now or hereafter have to the venue of any such action or proceeding
in any such court or that such action or proceeding was brought in an
inconvenient court and agrees not to plead or claim the same;

                  (c) agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the
Borrower at the address set forth in Section 10.2 or at such other address of
which the Lender shall have been notified pursuant thereto;

                  (d) agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction;

                  (e) waives, to the maximum extent permitted by law, any right
it may have to claim or recover in any legal action or proceeding referred to in
this subsection and waives any claim to, and agrees that neither the Agent nor
any Lender shall have any liability for, any special, indirect, consequential or
punitive damages in any action or proceeding arising out of or related to this
Agreement or any other Loan Document.


                                       81

This consent to jurisdiction is made pursuant to New York General Obligations
Law Section 5-1402.

            Section 10.14 Headings; Table of Contents. The Section and other
headings contained in this Agreement and the Table of Contents which precedes
this Agreement are for reference purposes only and shall not control or affect
the construction of this Agreement or the interpretation hereof in any respect.

            Section 10.15 Acknowledgments. Each Person constituting the Borrower
hereby acknowledges that:

                  (a) it has been advised by counsel in the negotiation,
execution and delivery of this Agreement and the Notes and the other Loan
Documents;

                  (b) neither the Agent nor any Lender has any fiduciary
relationship to any Person constituting the Borrower, and the relationship
between the Agent and the Lenders, on one hand, and each Person constituting the
Borrower, on the other hand, is solely that of debtor and creditor; and

                  (c) no joint venture exists among any Person constituting the
Borrower, the Agent or any Lender.

            Section 10.16 Judgement Currency/Withholding Tax.

                  (a) If for the purposes of obtaining a judgment in any court
with respect to any obligation of any Person constituting the Borrower under
this Agreement, the Notes or any other instrument or agreement executed and
delivered by the Borrower in connection therewith it becomes necessary to
convert into any other currency any amount in Dollars due thereunder, then such
conversion shall be made at the buying spot rate of exchange for freely
transferable Dollars at the close of business on the day before the day on which
the judgment is given at the place where such court is located. If there is a
change in such rate of exchange prevailing between the day before the day on
which the judgment is given and the date of the payment thereof, the Borrower
agrees to pay such additional amounts (if any) as may be necessary to insure
that the amount paid on such date is the amount in such other currency which,
when converted at such rate of exchange in effect on the date of payment, is the
amount then due in Dollars. Any amount due under this Section 10.16 will be due
as a separate debt and shall not be affected by or merged into any judgment
being obtained for any other sums due under or in respect of this Agreement, the
Notes or any other instrument or agreement executed and delivered by the
Borrower in connection therewith. In no event, however, shall the Borrower be
required to pay more Dollars at such rate of exchange when payment is made than
the amount of Dollars stated to be due.

                  (b) If any payment of the Obligations by any Subsidiary
Borrower which is organized or located in a jurisdiction outside the United
States of America is subject in such jurisdiction to any withholding or other
tax, levy, impost, charge fee, duty or deduction of any kind whatsoever (each, a
"Foreign Tax"), the Borrower shall pay to the Agent or Lender, as the case may
be, such additional amounts as will result in a net payment to the Agent or such
Lender equal to the amount such payee would have received had no such Foreign
Tax been imposed.

            Section 10.17 Waivers of Jury Trial. EACH PERSON CONSTITUTING THE
BORROWER, THE AGENT AND EACH LENDER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE
TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR
THE NOTES OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

            IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed and delivered by their proper and duly authorized officers as
of the day and year first above written.
