          (iv) If funds from the Retained Revenue Account have been disbursed
pursuant to (S)4.4.4(c)(i) for two (2) consecutive months, then the Lessor may,
but shall not be obligated to, apply any amounts then remaining in the Retained
Revenue Reserve Account and/or the Major Maintenance Reserve Account as a
prepayment of Basic Rent.

          (v) Upon the payment in cash in full of the Rent and satisfaction in

limited to, (a) the execution, in the Lessee's name and on its behalf, of each
of the Lease Documents and Project Documents to the extent such signature is
required and (b) the giving of notice or the taking of other action on the

             -----------------------
deduct from the Project Control Account the amount of any payment due from the
Lessee, the Parent and/or ITG to the Lessor under this Agreement or the other

as Additional Rent, any and all claims, expenses, damages, losses or liabilities
incurred by the Indemnified Party, including, without limitation, attorneys' and
experts' fees and disbursements, including, without limitation, appraisal fees,

imposed upon, incurred by or asserted or awarded against any Unit or any
Indemnified Party and in any way relating to or arising from or out of:

     (a) environmental matters to the extent set forth in either Environmental
     Indemnity Agreement (it being expressly acknowledged by the Lessee that
     each Environmental Indemnity Agreement provides that certain provisions
     thereof shall survive any foreclosure or any modification, release or
     discharge of any or all of the Security Documents or the payment of all
     Basic Rent and shall inure to the benefit of the Lessor and its successors
     and assigns);

                                      -15-

     any representative, lenders, agent, or contractor of the Lessee, occupant
     of the Host Site or the Project Site (including the Equipment) or invitee
     thereof, or (iii) which otherwise is in any way related to all or any
     portion of the Landfill Project or the Facility;

     (d) any liability asserted against, imposed or incurred by the Lessor in
     connection with or as a result of (i) the Assignment of Contracts, the

     agreements referred to in the Assignment of Contracts, the Collateral
     Assignment of Project Contracts or the Leasehold Mortgage or (iii) by
     reason of any alleged obligations or undertakings of the Lessor to perform
     or discharge any of the terms, covenants or agreements contained in any of
     such leases or other agreements;

     (e) without limitation the generality of the foregoing, the manufacture,
     purchase, acceptance or rejection, ownership, delivery, lease, use,
     possession, operation, condition, repair, replacement, reconstruction,
     return or other disposition of any Unit, including without limitation those
     in any way relating to or arising out of or alleged to arise out of (i) any
     latent or other defects whether or not discoverable by the Lessor or the

     (iii) any claim based on strict liability in tort and (iv) any and all
     license fees, assessments and sales, use, rent, property and other taxes

     however, taxes, fees and other charges based upon or measured by any
     Indemnified Party's net income), whether the same shall be payable by or
     billed or assessed to such Indemnified Party or the Lessee, together with
     any penalties or interest in connection therewith; or

     (f) (i) the preparation for, commencement and the continuation of the
     Lessor's rights relating to any Event of Default, whether or not the Lessor
     pursues such enforcement, (ii) reasonable expenses incurred by the Lessor
     if made a party to any action by a third party or in participating in any
     other legal proceeding relating to the Equipment, the Collateral or the
     Lease Documents, (iii) reasonable expenses incurred by the Lessor in
     exercising any right of self help pursuant to the Assignment of Contracts,
     the Collateral Assignment of Project Contracts, the Leasehold Mortgage or
     any other Security Document, (iv) any reasonable expenses incurred by the
     Lessor in administering the disposition of insurance proceeds or eminent
     domain proceeds or in considering matters for which the

                                      -16-
<PAGE>

     Lessee requests the Lessor's approval pursuant to, or which would otherwise
     be a violation of, the Lease Documents, and (v) all other reasonable
     expenses incurred by the Lessor in connection with the Lessee Obligations.

     In addition, the Lessee will defend with counsel of the Lessor's selection
(but with the approval of Lessee, which approval shall not be unreasonably
withheld, and at the Lessee's expense), indemnify, exonerate and save harmless
each Indemnified Party from and against any and all claims, expenses, damages,
losses or liabilities relating to any personal injury (including death) or
property damage asserted against any Indemnified Party on account of any act
performed or omitted to be performed in any way related to the Equipment and/or
the Collateral or on account of any transaction under any Lease Document.  The
Lessee shall be obligated under this section irrespective of whether any
Indemnified Party shall also be indemnified with respect to the same matter
under any other agreement by any other Person.  In the event the Lessee is
required to make any payment under this section, the Lessee shall pay to each
Indemnified Party any amount which after deduction of all taxes required to be
paid by such Party in respect of the receipt of such payment (after giving
credit for any savings in respect of any such taxes by reason of deductions,
credits or allowances available to the Indemnified Party in respect of the
payment of the expense indemnified against and of such other taxes) shall be
equal to the amount of such payment.  The Lessee and the Lessor shall each give
the other promptly upon obtaining knowledge thereof written notice of any matter
hereunder indemnified against; provided, however, that the failure to give such
                               --------  -------
notice shall not in any way affect, impair or diminish the Lessee's obligations
hereunder.  The obligation of indemnity contained in this Agreement shall
survive satisfaction of all or any portion of the Lessee Obligations, discharge
and/or release of any Lease Document or foreclosure thereunder.

     Notwithstanding the foregoing provisions of this section, an Indemnified
Party shall not be entitled to indemnification in respect of claims, expenses,
damages, losses or liabilities arising from acts of its, his or her own gross
negligence or willful misconduct to the extent that such gross negligence or
willful misconduct is determined by the final judgment of a court of competent
jurisdiction, not subject to further appeal, in proceedings to which such
Indemnified Party is a proper party.  The obligations under this section shall
constitute "Lessee Obligations" for all purposes of the Security Documents.

                                   ARTICLE 7
                    REPRESENTATIONS AND WARRANTIES OF LESSEE

     -------------------
the Lease Documents and the Project Documents to which the Lessee, the Parent or
ITG is or is to become a party and the transactions contemplated hereby and
thereby are within the power and authority of the Lessee,  the Parent or ITG
have been authorized by all necessary proceedings, and do not and will not (a)

Lessee, the Parent or ITG, (b) contravene any resolution of the stockholders or
of the Directors of the Lessee, the Parent or ITG, (c) contravene any provision
of, or constitute an event of default or event that, but for the requirement

default under, any other agreement, instrument, order or undertaking binding on
the Lessee, the Parent or ITG, or (d) result in or require the imposition of any
Lien on any of the properties, assets or rights of the Lessee, the Parent or
ITG, other than in favor of the Lessor or otherwise permitted under this
Agreement.  All consents of any nature necessary for the execution of the
Easement Agreement and the Sales Agreement by the Host and the other Project
Documents by the parties thereto (other than the Lessee) will be obtained on or
prior to the Closing Date.

7.3. Valid Obligations. Each of the Lease Documents and the Project Documents
     -----------------
to which the Lessee, the Parent and/or ITG is or is to become a party and all of
its respective terms and provisions are the legal, valid and binding obligations
of the Lessee, the Parent or ITG, as the case may be, enforceable in accordance
with its respective terms, except as limited by bankruptcy, insolvency,
reorganization, moratorium or other laws affecting the enforcement of creditors'
rights generally, and except as the remedy of specific performance or of
injunctive relief is subject to the discretion of the court before which any
proceeding therefor may be brought.

7.4. Approvals. The execution, delivery and performance of each of the Lease
     ---------
Documents and the Project Documents to which the Lessee, the Parent and/or ITG
is or is to become a party and the transactions contemplated herein and therein
do not require (a) any Approval (except filings under the UCC in connection with
the Collateral) or (b) the consent or approval of any creditors or trustees for
creditors of the Lessee, the Parent and/or ITG, or of any other Person, except
for such Approvals.

7.5. Title to Properties; Absence of Encumbrances. Lessee has good and
     --------------------------------------------
marketable title to all of the properties, assets and rights of every name and
nature now purported to be owned by it, including, without limitation, such
properties, assets and rights as are reflected in the Initial Financial
Statement (except such properties, assets or rights as have been disposed of in
the ordinary course of business since the date thereof), free from all Liens
except Permitted Liens, and, except as so disclosed, free from all defects of
title that might materially adversely affect any of such properties, assets or
rights.  All such properties and assets and all properties which are leaseholds
are free and clear of all title defects or objections and Liens of any nature
whatsoever, and are not, in the case of real property,

                                      -18-
<PAGE>

subject to any rights of way, building, use or other restrictions, easements,
exceptions, variances, reservations or limitations of any nature whatsoever
except, with respect to all such properties and assets, (i) provisions of
existing building and zoning laws, provided, that, such restrictions do not
                                   --------  ----
prohibit or materially impair the use of the premises or the conduct of the
Lessee's business, (ii) Liens for current taxes, assessments and other
governmental charges not yet due, (iii) easements and restrictions of record
which do not, individually or in the aggregate, prohibit or materially impair
the use of the premises or the conduct of the Lessee's business, and (iv) as
otherwise disclosed on Schedule 7.5. The rights, properties and other assets
                       ------------
presently owned, leased or licensed by the Lessee and described elsewhere in
this Agreement include all rights, properties and other assets necessary to
permit the Lessee to conduct its business in all material respects in the same
manner as its business has been conducted prior to the date hereof. At the time
the Lessee pledges, sells, assigns or transfers to the Lessor any instrument,
document of title, security, chattel paper or other property or any proceeds or
products thereof, or any interest therein, the Lessee shall be the lawful owner
thereof and shall have good right to pledge, sell, assign or transfer the same;
none of such properties shall at that time be pledged, sold, assigned or
transferred to any Person other than the Lessor or in any way encumbered (other
than with respect to Permitted Liens); and the Lessee shall defend the same
against the claims and demands of all Persons.

7.6. Insurance. The Lessee maintains insurance with financially responsible
     ---------
insurers which complies with the requirements of 9.4.  True and accurate copies
of the policies evidencing such insurance have been previously delivered to the
Lessor.

7.7. Financial Statements. The Lessee has provided to the Lessor (a) a
     --------------------
balance sheet of each of the Lessee and the Parent as of December 31, 1999, and
the statements of income, changes in stockholder's equity and cash flow of each
thereof for the fiscal year then ended, and related footnotes, internally
compiled by Lessor or the Parent, as the case may be, and (b) an unaudited
balance sheet of each of the Lessee and the Parent as of September 29, 2000, and
the statements of income, changes in stockholder's equity and cash flow of each
thereof for the fiscal period then ended (collectively, the "Initial Financial
Statement").  All such financial statements were prepared in accordance with
GAAP, consistently applied, and present fairly the financial position of the
Lessee and of the Parent, as the case may be, as of such dates and the results
of the operations of the Lessee and the Parent, respectively, for such periods.
There are no liabilities, contingent or otherwise, not disclosed in any of such
financial statements that involve a material amount.

7.8. No Material Adverse Change; No Event of Default; No Payments. Since the
     ------------------------------------------------------------
date of the Initial Financial Statement, which the Lessor has used to underwrite
the Transaction, there have been no changes in the assets, liabilities,
financial condition or business of the Lessee which could have a Material
Adverse Effect.  No Default or Event of Default under any Lease Document, or
default or event of default under any Project Document, has occurred and is
continuing.

7.9. Taxes. The Lessee has filed all federal, state and other tax and
     -----
information returns required to be filed, and has fully paid all taxes,
assessments and other governmental charges and levies, including interest and
penalties, due from the Lessee except any tax, assessment, charge or levy that
is being contested in good faith by appropriate proceedings and with respect to
which adequate reserves have been established and are being maintained in
accordance with GAAP and as to which no Lien has been filed to secure such tax,
assessment, charge or levy.  The Lessee has not executed any waiver of
limitations in respect of tax liabilities.  The Lessee has established on its
books reserves adequate for the payment of all federal, state and other tax
liabilities of which it has (or reasonably should have) knowledge.  The Lessee
has relied exclusively on the advice of its own advisers with respect to the tax
and accounting treatment of this Agreement and the other Lease Documents and
acknowledges that the Lessor has made no representation or warranty with respect
thereto.

7.10.  No Litigation. Except as set forth on Schedule 7.10, there is no
       -------------                         -------------
litigation, arbitration, proceeding or investigation pending or, to the Lessee's
knowledge, threatened against the Lessee that, if adversely determined, could
result in a material judgment not fully covered by insurance, could result in a
forfeiture of all or any substantial part of the property of the Lessee, or
could otherwise have a Material Adverse Effect.

7.11.  Compliance with Other Instruments, Laws, Etc. None of the Lessee, the
       --------------------------------------------
Parent nor ITG is in violation of (a) any Charter Document or resolution, (b)
any instrument or agreement binding on Lessee or affecting Lessee's property or
the Parent's interests in the Lessee which have been or will be pledged to
Lessor pursuant to the Pledge Agreement (c) any Legal Requirement or Approval,
in a manner which could reasonably expected to have a Material Adverse Effect;
nor has the Lessee, the Parent nor ITG received any notice of the violation of
any Legal Requirement or Approval from any government or regulatory authority
(including, without limitation, all applicable federal and state tax laws, ERISA
and Environmental Laws), the consequences of which could have a Material Adverse
Effect.

7.12.  Perfection of Liens. Upon execution and delivery of the Security
       -------------------
Documents and the filing of documents thereby required, the Lessor shall have
first-priority perfected liens on the Collateral, subject only to Permitted
Liens and entitled to priority under applicable law, with no financing
statements, chattel mortgages, real estate mortgages or similar filings on
record anywhere which conflict with such first-priority liens of the Lessor.

7.13.  Work; Plans and Specifications; Facility. All of the Facility Work
       ----------------------------------------
which has been performed and which is to be performed complies in all material
respects with all applicable Legal Requirements and Approvals, including,
without limitation, zoning, building and fire codes and health, safety and
Environmental Laws, rules and regulations.  To the best of Lessee's knowledge,
the Landfill Work which has been performed complies in all material respects
with all applicable Legal Requirements and Approvals, including, without
limitation, zoning, building and fire codes and health, safety and

                                      -20-
<PAGE>

Environmental Laws, rules and regulations. The Plans and Specifications attached
hereto as Exhibit D are a true, correct and complete copy of all plans and
          ---------
specifications, as amended, that relate to the Facility (including the
Equipment). The Facility (including the Equipment) has been completed in
compliance in all material respects with and as contemplated by the Plans and
Specifications, the Facility (including the Equipment) is functioning in
compliance in all material respects with and as contemplated by the Plan and
Specifications and has, if and to the extent required by any Project Document,
been accepted unconditionally and irrevocably by the Host and the Utility
pursuant to the Project Documents in accordance with all applicable requirements
of the Project Documents.

7.14.  Facility Approvals Obtained. All Approvals necessary for the
       ---------------------------
construction, installation, operation and maintenance of the Facility (including
the Equipment) have been obtained so as to comply with all Legal Requirements in
all material respects, and the Facility complies in all material respects with
all such Approvals.  Without limiting the generality of the foregoing, the
Facility has been certified and remains, and will after the Transaction is
effected remain, a qualifying facility or a qualifying small power facility as
defined under PURPA and FERC regulations and practices.  No violation exists of
any Legal Requirement as it pertains to the Lessee or the Facility.  To the best
of the Lessee's knowledge, the Landfill Project has all Approvals for the
construction, operation and maintenance of the Landfill Project (including the
Host Site) in compliance with all Legal Requirements, the Landfill Project
complies in all material respects with all such Approvals and no violation
exists of any Legal Requirement as it pertains to the Host or the Landfill
Project.

7.15.  Environmental Matters. Except as set forth on Schedule 7.15:
       ---------------------                         -------------

     7.15.1.   All Approvals which are required under all Environmental Laws in
connection with the Facility and the operation of Lessee's business have been
obtained, except to the extent failure to have any such Approvals would not have
a Material Adverse Effect.  The Lessee and Facility are in compliance with the
terms and conditions of all such Approvals, and is also in compliance with all
other limitations, restrictions, conditions, standards, prohibitions,
requirements, obligations, schedules and timetables contained in any applicable
Environmental Law or in any regulation, code, plan, order, decree, judgment or
injunction issued, entered, promulgated or approved thereunder, except to the
extent failure so to comply would not, individually or in the aggregate, have a
Material Adverse Effect.

     7.15.2.     No notice, notification, demand, request for information,
citation, summons or order has been received by Lessee or, to the best of
Lessee's knowledge, has been issued, no complaint has been filed, no penalty has
been assessed and no investigation or review is pending or, to the best of
Lessee's knowledge, threatened by any governmental or other entity with respect
to any alleged failure by the Lessee to have any Approval required in connection
with the operation of the Facility or the conduct of its business or with
respect to any Environmental Laws, including, without limitation, Environmental

                                      -21-
<PAGE>

Laws relating to the generation, treatment, storage, recycling, transportation,
disposal or release of any Hazardous Materials.  The Lessee has not been
identified as a potentially responsible party (as that term has been construed
pursuant to CERCLA, or any similar state or local laws) at any site.

     7.15.3.     No material oral or written notification of a release of a
Hazardous Material has been filed by or on behalf of the Lessee and no property
now or previously owned, leased or used by the Lessee is listed or proposed for
listing on the National Priorities List under CERCLA, as amended, or, to the
best of Lessee's knowledge, on any similar state list of sites requiring
investigation or clean-up.

     7.15.4.     There are no Liens arising under or pursuant to any
Environmental Laws on any of the real property or properties owned, leased or
used by the Lessee and no governmental actions have been taken or are in process
which could subject any of such properties to such Liens or, as a result of
which the Lessee would be required to place any notice or restriction relating
to the presence of Hazardous Materials at any property owned by it in any deed
to such property.

     7.15.5.     Neither the Lessee nor, to the Lessee's knowledge, any previous
owner, tenant, occupant or user of any property owned, leased or used by the
Lessee has (i) engaged in or permitted any operations or activities upon or any
use or occupancy of such property, or any portion thereof, for the purpose of or
in any way involving the handling, manufacture, treatment, storage, use,
generation, release, discharge, refining, dumping or disposal (whether legal or
illegal, accidental or intentional) of any Hazardous Materials on, under, in or
about such property, except in compliance with all Environmental Laws, or (ii)
transported any Hazardous Materials to, from or across such property except in
compliance with all Environmental Laws; nor to the Lessee's knowledge have any
Hazardous Materials migrated from other properties upon, about or beneath such
property nor, to the Lessee's knowledge, are any Hazardous Materials presently
constructed, deposited, stored or otherwise located on, under, in or about such
property except in compliance with all Environmental Laws.

7.16.  Disclosure. No representations and warranties made by the Lessee, the
       ----------

factual information heretofore or contemporaneously furnished by or on behalf of
the Lessee, the Parent and/or ITG to the Lessor, in connection with any of the
transactions contemplated by any of the Lease Documents or Project Documents
contains any untrue statement of fact or omits to state a fact necessary in
order to make the statements contained therein not misleading in light of the
circumstances in which they are made.  Except as disclosed herein, there is no
fact which has resulted in, or which could in the future result in, a Material
Adverse Effect.

7.17.  Solvency. Both before and after giving effect to the transactions
       --------
contemplated by the Lease Documents and the Project Documents, neither the
Lessee nor ITG or, to Lessee's

insolvent by the Indebtedness incurred in connection therewith, (ii) has or will
be left with unreasonably small capital with which to engage in its business,
(iii) has incurred or will incur Indebtedness beyond its ability to pay such
Indebtedness as it matures, and (iv) has or will fail to have assets (both
tangible and intangible) having a present fair salable value in excess of the
amount required to pay the probable liability on its then existing debts
(whether matured or unmatured, liquidated or unliquidated, absolute fixed or
contingent).

7.18.  No Broker. None of the Lessee, the Parent, ITG, nor anyone acting on
       ---------
its behalf, has dealt with any broker, finder or other person or entity who or

finder's fees (or the like) has or may be incurred by or on behalf of the
Lessee, the Parent and/or ITG in connection with any transaction contemplated by
the Lease Documents or the Project Documents.  The Lessee agrees to defend, save
harmless and indemnify the Lessor from any and all such claims on account
thereof.  This provision shall survive the payment of the Rent and payment and
performance of all other Lessee Obligations, and shall continue in full force
and effect so long as the possibility of any such claim exists.

                    REPRESENTATIONS AND WARRANTIES OF LESSOR

     The Lessor represents and warrants to the Lessee as the date hereof and as
the Closing Date that:

8.1. Title. The Lessor has received whatever title to the Equipment was
     -----
conveyed to it by the Lessee and that the Equipment is free of Liens which may
result from any claims against the Lessor, except to the extent that such Liens
arise from the failure of the Lessee to perform any of the Lessee's obligations
hereunder.

8.2. Corporate Authority. The Lessor has full power and authority to lease
     -------------------
the Equipment to the Lessee in accordance with the terms hereof.

8.3. Warranties. THE WARRANTIES OF THE LESSOR SET FORTH IN THIS ARTICLE 8 ARE
     ----------
EXCLUSIVE AND IN LIEU OF ALL OTHER REPRESENTATIONS OR WARRANTIES OF THE LESSOR
WHETHER STATUTORY, WRITTEN, ORAL OR IMPLIED, AND THE LESSOR HAS NOT MADE AND
DOES NOT HEREBY MAKE, NOR SHALL IT BE DEEMED BY VIRTUE OF HAVING LEASED THE
EQUIPMENT PURSUANT TO THIS AGREEMENT TO HAVE MADE, ANY REPRESENTATION OR
WARRANTY AS TO THE MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, DESIGN OR
CONDITION OF, OR AS TO THE QUALITY OF THE WORKMANSHIP IN, THE EQUIPMENT, but the
Lessor authorizes the Lessee, at the Lessee's expense, to assert during the
Term, so long as no Default or Event of Default shall have occurred and be
continuing, all of the Lessor's rights under any previous manufacturer's,
vendor's or dealer's warranty with respect to the Equipment, and the Lessor
agrees to cooperate with the Lessee in asserting such rights in order to obtain
the benefit thereof; provided, however, that the Lessee shall not attempt to
                     --------  -------
enforce such rights unless (i) the Lessee shall first notify the Lessor of the
Lessee's intention to enforce such rights and shall furnish to the Lessor such
information with respect thereto as the Lessor may reasonably request and (ii)

involve any danger of sale, forfeiture or loss of any Unit or create the danger
of the Lessor's incurring criminal liability or other liability for which
indemnification by the Lessee, satisfactory to the Lessor, of the Lessor and all
other Indemnified Parties is not provided.  Any amount received by the Lessee as
payment under any warranty pursuant to the above authorization shall be applied

Account.  The provisions of this section have been negotiated and agreed to by
the parties hereto and, except to the extent otherwise expressly provided in

awards received by it or payable to it or on its behalf in connection with any
condemnation, damage or destruction of all or any portion of the Facility
(including, without limitation, the Project Site and the Equipment) or any
requisitioning of any thereof by any governmental authority, which in either
case does not constitute an Event of Loss, for application as the Lessor may
determine in its sole and absolute discretion to (a) the timely repair of the
Facility (including, without limitation, the Project Site and the Equipment) in
the case of such damage or destruction or (b) the timely payment of expenses of
the Facility (including, without limitation, the Project Site and Equipment) in

wherever the same may be located, without demand or notice, without any court

          (d) The Lessor may recover from the Lessee, with respect to any and
all Units of Equipment, and with or without repossessing the Equipment, as
damages for loss of the bargain and not as a penalty and as reasonable rent for

repossessed or accepted the surrender of the Equipment and either does not
exercise its rights under (S)12.3 or permanently discontinues the exercise of
its rights under (S)12.3, the Lessor shall sell, lease or otherwise dispose of

under this Article 12 is exclusive of any right or remedy herein or by law or

     compliance of the Equipment and/or the Facility with Legal Requirements or
     Approvals applicable to it, including, Environmental Laws; and

(j)  take such action hereunder, or refrain from acting hereunder, as the Lessor
     may, in its sole and absolute discretion, from time to time determine, and
     without any limitation whatsoever, to carry out the intent of this section.

The Lessee shall be liable to the Lessor for all costs paid or incurred for the
equipping, completion, operation and maintenance of all or any part of the
Equipment and/or the Facility, whether the same shall be paid or incurred
pursuant to the provisions of this section or otherwise, and all payments made
or liabilities incurred by the Lessor

                                      -45-

hereunder of any kind whatsoever shall be deemed Lessee Obligations under this
Agreement and shall be secured by the Security Documents. Any costs so paid or
incurred by the Lessor shall be paid by the Lessee to the Lessor upon demand
with interest at the Default Interest Rate from the date of payment by the
Lessor to the date of payment to the Lessor. In the event the Lessor takes
possession of all or any portion of the Equipment and/or the Facility and
assumes control of such operation and/or maintenance as aforesaid, it shall not
be obligated to continue such operation and/or maintenance longer than it shall
see fit and may thereafter, at any time, change any course of action undertaken
by it or abandon such operation and/or maintenance and decline to make further
payments for the account of the Lessee whether or not the Facility shall require
continued operation. For the purpose of this section, the operation and/or
maintenance of the Equipment and/or the Facility shall be deemed to include any

foreclosure, exercise of set-off or pledge rights and/or by suit in equity,

are evidenced, including as permitted by applicable law the obtaining of the ex

Lessee shall have the right to purchase all, but not less than all, Units at the
expiration of the Term at a price equal to their then fair market value. The
Lessee shall give the Lessor written notice one-hundred eighty (180) days prior
to the end of the Term of its election to exercise such option. Payment of the
option price shall be made on the last day of the Term to the Lessor at an
account to be designated by the Lessor by wire transfer against delivery of a
bill of sale transferring each Unit to the Lessee as is, where is, and with all
faults. If the Lessor and the Lessee are unable to arrive at an agreement as to
fair market value within forty-five (45) days following the aforesaid notice,
the fair market value of each such Unit shall be determined in accordance with
the appraisal procedure described below.

     Appraisal Procedure.     The Appraisal Procedure shall be a procedure

any Unit, one chosen by the Lessee and one chosen by the Lessor, shall mutually
agree upon the amount in question.  The Lessor and the Lessee, as the case may
be, shall deliver a written notice to the other party appointing its appraiser
within 10 business days after receipt from the other party of a written notice
appointing that party's appraiser.  If within fifteen (15) Business Days of the
appointment of the last of the two appraisers as described above, the two
appraisers are unable to agree upon the amount in question, a third independent
appraiser, who shall not be a manufacturer of any Unit, shall be chosen within
five (5) Business Days thereafter by the mutual consent of such first two
appraisers or, if such first two appraisers fail to agree upon the appointment
of a third appraiser, such appointment shall be made by an authorized
representative of the American Arbitration Association or any organization
successor thereto.  The decision of each appraiser so appointed and chosen shall
be given within fifteen (15) Business Days after the selection of such third
appraiser.  The average of the three appraisals arrived at by such three
appraisers shall be binding and conclusive on the Lessee and the Lessor.  The
Lessor and the Lessee shall pay the fees and expenses of the respective
appraisers appointed by them and shall share equally the fees and expenses of
the third appraiser, if any.

     Re:  Letter of Credit No. NY-20512-30029001 dated December 28, 2000
          In the Face Amount of $8,500,000.00
          Issued by Citibank, N.A. to ABB Energy Capital L.L.C.
          For the Account of Keystone Recovery, Inc. (the "Letter of Credit")

Dear Rich:

     ABB Energy Capital L.L.C., as Lender, and Keystone Recovery, Inc., as
Borrower, are today entering into a loan arrangement evidenced by a Term Note of
even date herewith in the original principal amount of $8,300,000.00 made
payable by Borrower in favor of Lender (the "Note") and secured by the Letter of
Credit. This Letter Agreement sets forth and confirms various agreements of
Borrower and Lender regarding the Note, the Letter of Credit and the
transactions contemplated in connection therewith.

     Lender and Borrower entered into a certain Commitment Letter dated October
23, 2000 (the "Commitment Letter") in connection with financing to be provided
to Borrower related to Borrower's activities at the Keystone Landfill in
Lackawanna County, Pennsylvania (the "Project"). The parties acknowledge that,
although the Commitment Letter contemplates a loan to the Borrower, the parties
have subsequently agreed to enter into a sale/lease back transaction on
substantially the same terms and conditions set forth in the Commitment Letter.

     The Commitment Letter sets forth various conditions that must be satisfied
prior to the closing of the financing transaction (the "Financing"). Those
conditions (the "Closing Conditions") include, but are not limited to, "(i)
changes occurring in the market or financial condition of Project participants
or otherwise affecting the Project, (ii) acceptable results of [Lender's] due
diligence including the need to revise or update assumptions, and (iii)
satisfactory documentation, in each case determined in [Lenders] sole
                            -----------------------------------------
discretion." (emphasis added)
-----------

     Although the Commitment Letter contemplates a closing no later than
December 15, 2000, the parties have not yet completed all the tasks necessary to
close the Financing. The Borrower has requested, and the Lender has agreed to,
an extension of the outside closing date for the Financing from December 15,
2000 to February 8, 2001. In addition, in order to accommodate certain financial
objectives of the Borrower and its parent company, The IT Group, Inc. which are
unrelated to the Financing, the Borrower has requested that, prior to the end of
the calendar year 2000, the Lender advance the full amount of the contemplated
Financing ($8,300,000.00) (the "Proceeds") even though the Closing Conditions
have not been met. Subject to the terms and conditions of this Letter
<PAGE>

Agreement, Lender has agreed so to advance the Proceeds as a loan to the
Borrower on the date hereof

     In consideration of the Lender advancing the Proceeds as contemplated
herein, the Borrower will, prior to the advance of the Proceeds, pay to the
Lender in immediately available funds the Closing Fee equal 1.5% of the Proceeds
contemplated in the Commitment Letter. The Closing Fee will be earned upon the
payment thereof and will not be refundable under any circumstances.

     The indebtedness incurred as a result of the Lender's advance of the
Proceeds will be evidenced by the Note, a copy of which is attached hereto as
Exhibit A. The original executed Note shall be delivered to the Lender prior to
the Lender's advance of the Proceeds.

     The indebtedness evidenced by the Note shall be secured by the Letter of
Credit, a copy of which is attached hereto as Exhibit B. The original Letter of
Credit shall be delivered to the Lender prior to the Lender's advance of the
Proceeds.

     Prior to the Lender's advance of the Proceeds, the Borrower will execute
the Agreement and Lease pursuant to which the Financing will be implemented if
and when the closing of the Financing occurs. The original Agreement and Lease
as executed by Borrower will be delivered to Lender's counsel, Goulston &
Storrs, P.C., to hold in escrow pending a closing of the Financing and Lender's
execution and delivery of the Agreement and Lease incident thereto. The parties
acknowledge that the Agreement and Lease as executed by Borrower as aforesaid
contains certain blanks and is missing various information, including, without
limitation, the schedules and exhibits thereto. Prior to and as a condition of
closing the Financing, in addition to and consistent with the other Closing
Conditions and the conditions to closing set forth in the Agreement and Lease,
the parties must finalize and complete the Agreement and Lease to Lender's sole
and absolute satisfaction.

     Even though the Proceeds will already have been advanced pursuant to the
terms of this Letter Agreement, the parties contemplate continuing to work
toward a closing of the Financing as contemplated by the Commitment Letter,
including, without limitation, satisfaction of the Closing Conditions and all
conditions to closing set forth in the Agreement and Lease. If the Financing is
so closed on or prior to February 8, 2001 (the "Outside Closing Date") to the
sole and absolute satisfaction of the Lender, the Lender will release the Letter
of Credit and return the original Note to the Borrower simultaneously with such
closing, and the documents executed in connection with such closing shall
thereafter govern the relationship of the parties.

     The Borrower shall pay all costs and expenses of Lender (including, without
limitation, all attorneys' fees and costs) incurred in connection with the loan
secured by the Letter of Credit described herein and/or the Financing,
including, without limitation, the Lender's costs of due diligence, document
preparation and negotiation, collection and/or enforcement. The Borrower hereby
acknowledges that the obligation to pay such costs and expenses is evidenced by
the Note in addition to the original principal amount thereof and is secured by
the Letter of Credit.

     The Lender shall be entitled to accelerate payment of all amounts due under
the Note (including principal, interest and other amounts due thereunder) under
the following circumstances:


                                      2
<PAGE>

     (a)  The Financing does not close on or prior to the Outside Closing Date
     for any reason, including the failure to satisfy all of the Closing
     Conditions and the conditions to closing set forth in the Agreement and
     Lease to the Lender's sole and absolute satisfaction; or

     (b) The Borrower defaults in any of its obligations hereunder or under the
     Note; or

     (c) The Borrower indicates that it does not intend to close the Financing
     on or prior to the Outside Closing Date; or

     (d) Any bankruptcy or insolvency filing is made by or against the Borrower
     or its parent company, The IT Group, Inc..

     Lender shall be entitled so to accelerate payment under the Note without
prior notice to Borrower, in which event all amounts (including principal,
interest and other amounts due thereunder) will immediately be due and payable,
and Lender will be entitled draw on the Letter of Credit in full or in part to
pay all such amounts. Lender will also be entitled, at its option, to draw on
the Letter of Credit to make any mandatory or voluntary prepayment under the
Note rather than accept payment directly from Borrower. If the Lender draws on
the Letter of Credit as aforesaid, the Commitment Letter automatically will
terminate and the executed Agreement and Lease will be voided, in each case,
without the need for further action by any party.

     The terms and provisions of this Letter Agreement are intended to be
binding upon and inure to the benefit of the parties hereto. Borrower may not
assign its rights or obligations hereunder without the prior written consent of
Lender.
