     to be made by Obligor to Obligee shall be made in immediately available
     funds not later than 12:00 noon Eastern time. In the event of any
     assignment to an Assignee pursuant to Section 14(b) hereof, all payments
     which are assigned to such Assignee, whether Payments, Supplemental
     Payments or otherwise, shall be paid in such manner as shall be designated
     by obligee or such Assignee. Time is of the essence in connection with the
     payment of Payments and Supplemental Payments.

     Whenever any payment hereunder shall be stated to be due on a day which is
     not a day on which banks are required to be open for business in Boston,
     Massachusetts (a "Banking Day"), such payment shall be made on the next
     succeeding Banking Day.

     8. Net Financing. This Agreement is a net financing agreement. Obligor
        -------------
acknowledges and agrees that Obligor's obligations hereunder, including, without
limitation, its obligations to make Payments for all Equipment financed
hereunder, to pay all Supplemental Payments payable hereunder and under each
other Obligor Document, shall be unconditional and irrevocable under any and all
circumstances, shall not be subject to cancellation, termination, modification
or repudiation by Obligor, and shall be paid and performed by Obligor without
notice or demand and without any abatement, reduction, diminution, setoff,
defense, counterclaim or recoupment
<PAGE>

whatsoever, including, without limitation, any abatement, reduction, diminution,
setoff, defense, counterclaim or recoupment due or alleged to be due to, or by
reason of, any past, present or future claims which Obligor may have against
Obligee, any Assignee, any manufacturer or supplier of the Equipment or any part
or Item thereof, or any other Person for any reason whatsoever or any defect in
the Equipment or any part or Item thereof, or the condition, design, operation
or fitness for use thereof, or any damage to, or any loss or destruction of, the
Equipment or any part or Item thereof, any Liens or rights of others with
respect to the Equipment or any part or Item thereof, or any prohibition or
interruption of or other restriction against Obligor's use, operation or
possession of the Equipment or any part or Item thereof, for any reason
whatsoever, or any interference with such use, operation or possession by any
Person or entity, or any default by Obligee in the performance of its
obligations herein contained, or any other indebtedness or liability, howsoever
and whenever arising, of Obligee, or of any Assignee, or of Obligor to any other
Person, or by reason of insolvency, bankruptcy or similar proceedings by or
against Obligee, any Assignee or Obligor, or for any other reason whatsoever,
whether similar or dissimilar to any of the foregoing, any present or future law
to the contrary notwithstanding; it being the intention of the parties hereto
that all Payments and Supplemental Payments payable by Obligor hereunder shall
continue to be payable in all events and in the manner and at the times herein
provided, without notice or demand, unless the obligation to pay the same shall
be terminated pursuant to the express provisions of this Agreement.

     9.   Grant of Security Interest; Equipment to be and Remain Personal
          ---------------------------------------------------------------
Property.  This Agreement is a financing intended as security. Obligor hereby
--------
grants to Obligee a security interest in the Equipment, the Required
Alterations, the Optional Alterations and all proceeds thereof as collateral
security for the payment and performance by Obligor of obligor's obligations as
Obligor hereunder. It is the intention and understanding of both Obligee and
Obligor, and Obligor shall take all such actions as may be required to assure,
that the Equipment shall be and at all times remain personal property,
notwithstanding the manner in which the Equipment may be attached or affixed to
realty. Obligor shall obtain and record such instruments and take such steps as
may be necessary to prevent any Person from acquiring any rights in the
Equipment by reason of the Equipment being claimed or deemed to be real
property. Upon request by Obligee, Obligor shall obtain and deliver to Obligee
valid and effective waivers, in recordable form, by the owners, landlords and
mortgagees of the real property upon which the Equipment or any Item of
Equipment is located or certificates of Obligor that it is the owner of such
real property or that such real property is not leased and/or mortgaged;
provided, that if an Item is located on a Site designated as a National Priority
--------
Fund Site (or any similar designation) pursuant to applicable Environmental
Laws, the Obligee may in lieu of delivering waivers from owners, landlords or
mortgagees, deliver to the Obligee evidence, reasonably satisfactory to the
Obligee, of the Obligor's currently effective contractual arrangements with
respect to such Site, so long as such contractual arrangements do not provide
for any lien or security interest in such Item. Obligor shall cause each Item of
Equipment subject to motor vehicle titling and registration laws to be titled in
the name of Obligor, as owner, with Obligee or Assignee, as applicable to be
shown as sole lienholder, and shall cause all certificates of title to be
promptly furnished to Obligee.

     10.  Use of Equipment; Compliance with Laws. Obligor agrees that the
          ----------------------------------------
Equipment will be
<PAGE>

used and operated solely in the conduct of its business and in compliance with
any and all Remediation Contracts, insurance policy terms, conditions and
provisions and with all statutes, laws, ordinances, rules and regulations of any
Federal, state or local governmental body, agency or authority applicable to the
use, management and operation of the Equipment, including, without limitation,
all applicable Environmental Laws (including without limitation, those
pertaining to the operation of dewatering equipment and the disposal of any
solid wastes resulting therefrom) and with the terms of all Remediation
Contracts, and will promptly rectify any noncompliance therewith, and including,
in the case of any Item subject to motor vehicle titling and registration laws,
all titles, registrations, registration plates, permits, licenses, and all
renewals thereof. Obligor shall procure and maintain in effect all licenses,
registrations, certificates, permits, approvals and consents required by
Federal, state or local laws or by any governmental body, agency or authority in
connection with the ownership, delivery, installation, use and operation of each
Item of Equipment, including without limitation, those required by Environmental
Laws. Obligor will use and maintain the Equipment in a careful and proper
manner, in accordance with all Remediation Contracts and the manufacturer's or
supplier's instructions or manuals, and only by competent and duly qualified
personnel authorized by Obligor. The Equipment will at all times be and remain
in the possession and control of Obligor; provided, that the Obligor may for
                                          --------
temporary periods not exceeding 30 days in length relinquish possession and
control of any Item to the manufacturer or to an independent contractor, for
purposes of repair or alteration required or permitted hereunder. The Equipment
shall in no event be located outside of the continental limits of the United
States. Obligor shall use every reasonable precaution to prevent loss or damage
to each Item of Equipment from fire and other hazards.

     10A. Certain Covenants. All storage and use of Hazardous Substances in
          -------------------
connection with the Equipment, and the installation and de-installation of the
Equipment, shall be in strict compliance with Environmental Laws applicable
thereto. Obligor will promptly give written notice to Obligee of the occurrence
of any Event of Loss or Event of Default, of the commencement of any litigation
or proceedings affecting Obligor from time to time which, if adversely
determined, could have a material adverse effect on Obligor's business,
operations or financial condition taken as a whole or which could otherwise
affect the Equipment, or of any dispute between Obligor and any governmental
regulatory body or other party that involves any of the Equipment.

In addition to the foregoing,

     (1) Obligor will promptly provide the Obligee with written notice:

          (a) upon the Obligor's obtaining knowledge of any cancellation or
     threatened cancellation or material adverse change in any insurance

     (whether formal or informal);

          (b) (intentionally omitted);

          (c) upon the Obligor's obtaining knowledge of any violation or alleged

     writing to any governmental authority or which could materially adversely
     affect the Obligor or the Equipment;

          (e) upon the Obligor's receipt of any notice of violation or alleged
     violation of any Environmental Laws or of any Release or threatened Release
     of Hazardous Materials, including a notice or claim of liability or
     potential responsibility from any third party (including without limitation
     any federal, state or local governmental officials) and including notice of
     any formal inquiry, proceeding, demand, investigation or other action, with
     regard to (i) the Obligor's or any person's operation of the Equipment,
     (ii) contamination at or from the Equipment or (iii) investigation or
     remediation of offsite locations at which the Obligor or its predecessors
     are alleged to have directly or indirectly disposed of Hazardous Materials
     from a Site; or

          (f) upon the Obligor's obtaining knowledge that any expense or loss
     has been incurred by such governmental authority in connection with the
     assessment, containment, removal or remediation of any Hazardous materials
     at or from a Site, with respect to which the Obligor may be liable or for
     which a Lien may be imposed on the Equipment; or

          (g) that Obligor is or shall be named party to any claim, action,
     cause of action, complaint, legal or administrative proceeding arising out
     of any third party's incurrence of costs, expenses, losses or damages of
     any kind whatsoever in connection with the Release of Hazardous Materials
     at or from a Site, or in excess of such costs and expenses payable or
     reimbursable under any Remediation Contract.

     In addition to the foregoing, obligor will provide to obligee:

          (h) as soon as practicable after request by the Obligee from time to
     time, a written report of an investigation, conducted to the satisfaction
     of the Obligee, by a consultant to be selected or approved by the Obligee,
     as to any significant environmental, health or safety violations, hazards
     or liabilities to which Obligor or Guarantor may be subject in respect of
     the Equipment or a Site;

          (i) promptly and in any event within five Business Days after receipt
     thereof by Obligor or Guarantor, a copy of each notice, citation or other
     communication from the United States Environmental Protection Agency, any
     state environmental protection agency, any court or other governmental
     Person, and of each consent agreement, consent decree, judgment or other
     document with any such Person, in each case asserting an actual or
     potential violation, fine, penalty, enforcement action or liability of
     obligor or Guarantor under any Environmental Laws in respect of the
     Equipment or a Site, or otherwise if the effect or adverse determination
     thereof would reasonably have a materially adverse effect on the
     properties, condition (financial or otherwise), operations or business of
     obligor and of Guarantor taken as a whole.
<PAGE>

     (2) except in accordance with Environmental Laws and as set forth in

          handling, processing, storage or disposal of Hazardous Materials;

                (ii) neither Obligor nor any of its subcontractors have released
          or will release any Hazardous Materials at or from a Site; and

                (iii) there have been and will be no unpermitted Releases or
          threatened Releases which would result in a lien upon such Equipment;
          and there have been and will be no unpermitted Releases or threatened
          Releases by Obligor or any of its subcontractors which would
          reasonably have a material adverse effect on the environment or the
          value of the property at or in the vicinity of a Site;

     (3) if any unpermitted Release or Disposal of Hazardous Materials shall
occur or shall have occurred as a result of the operation of the Equipment not

necessary to comply with all Environmental Laws or to preserve the value of the
Equipment;

     (4) Obligor will at all times maintain in effect any indemnification of

performance bonds, or other financial assurance as is required by applicable law
or reasonably required by the Obligee or by any Remediation Contract; and

     (5) any Hazardous Materials that will be handled by the Equipment or that
will be generated by the Equipment, to the best knowledge of Obligor, will be
transported offsite only by carriers having an identification number issued by

     11. Maintenance and Repair of Equipment.  Obligor agrees, at its own cost
         ------------------------------------
and expense, to keep, repair, maintain and preserve the Equipment in good order
and operating condition, and in compliance with such maintenance and repair
standards and procedures as are set forth in the manufacturer's manuals
pertaining to the Equipment, and as otherwise may be required to enforce
warranty claims against each vendor and manufacturer of each item of Equipment,
and in compliance with all Remediation Contracts and requirements of law
applicable to the maintenance and condition of the Equipment, including, without
limitation, environmental, noise and pollution laws and regulations (including
notifications and reports). Obligor shall, at its own cost and expense, supply
the necessary power and other items required in the operation of the Equipment.
Obligor hereby waives any right now or hereafter conferred by law to make
repairs on the Equipment at the expense of Obligee.
<PAGE>

     12.  Replacements: Alterations: Modifications; Substitutions.
          --------------------------------------------------------

          (a) In case any Item of Equipment (or any equipment, part or appliance
     therein) is required to be altered, added to, replaced or modified in order
     to comply with any laws, regulations, requirements or rules ("Required
     Alteration") pursuant to Sections 10 or 11 hereof, Obligor agrees to make
     such Required Alteration at its own expense and an interest in the same
     shall immediately vest in Obligee and the same shall be subject to the
     terms of this Agreement. Obligor may make any optional alteration to any
     Item of Equipment ("Optional Alteration") provided such Optional Alteration
     does not impair the value, use or remaining useful life of such Item of
     Equipment. An interest in such optional Alteration shall be immediately
     vested in Obligee and the same shall be subject to this Agreement. Obligor
     agrees that, within 30 days after the close of any calendar quarter in
     which Obligor has made any Required Alterations that could have an adverse
     effect upon the value, utility or useful life of any Item of Equipment,
     Obligor will give written notice thereof to Obligee describing, in
     reasonable detail, the Required Alterations and specifying the cost thereof
     with respect to such Item of Equipment and the date or dates when made. Any
     parts installed or replacements made by Obligor upon any Item of Equipment
     pursuant to its obligation to maintain and keep the Equipment in good
     order, operating condition and repair under Section 11 hereof shall be
     considered accessions to such Item of Equipment and an interest therein
     shall be immediately vested in Obligee and the same shall be subject to
     this Agreement. Except as required or permitted by the provisions of this
     Section 12, Obligor shall not modify an Item of Equipment without the prior
     written authority and approval of Obligee.

          (b) With the prior written consent of Obligee, not to be unreasonably
     withheld, Obligor shall be permitted to substitute for any Item of
     Equipment then subject to this Agreement (provided that, in Obligor's good
     faith opinion, as evidenced by a certificate of its President, treasurer or
     chief financial officer, such Item shall have become no longer useful, or
     surplus, to Obligor in its business), like kind, equipment having a fair
     market value and utility equal to or greater than such Item. Such fair
     market value and utility shall be determined by the Obligee in its
     reasonable discretion. If such substitution is permitted by the Obligee,
     the item of equipment so substituted shall be considered an "Item of
     Equipment" subject to this Agreement and the interest of the Obligee
     hereunder, and Obligor shall execute such documents as may be reasonably
     requested by Obligee to evidence its interest therein, and Obligee's rights
     and interests in, to and under the item of equipment having been so
     substituted shall be terminated and Obligee shall execute and deliver to
     Obligor a transfer and release of its interest in such item to Obligor, "as
     is where is" without representation or warranty of any kind.

     13.  Identification Marks; Inspection.  Obligor agrees, upon the request of
          ---------------------------------
Obligee, at Obligor's sole cost and expense, to place markings on the Equipment
by stencil or by a metal tag or plate affixed thereto showing plainly,
distinctly and conspicuously Obligee's security interest therein; provided,
however, that such identification markings are to be placed so as not to
interfere with the usefulness of such Item of Equipment. If during the Term any
such identification marking shall at any time be defaced or
<PAGE>

destroyed, Obligor shall immediately cause such defaced or destroyed
identification marking to be restored or replaced. Obligor shall not allow the
name of any Person to be placed upon any Item of Equipment as a designation
which might be interpreted as indicating a claim of a security interest therein
by any Person other than Obligee or any Assignee. Upon the request of Obligee,
Obligor shall make the Equipment available to Obligee for inspection and shall
also make Obligor's records pertaining to the Equipment available to Obligee for
inspection.

     14.  Assignments and Subleasing.

     CONSENT OF OBLIGEE, SUBLEASE OR OTHERWISE RELINQUISH POSSESSION OF ANY ITEM
     OF EQUIPMENT, OR ASSIGN, TRANSFER OR ENCUMBER ITS RIGHTS, INTERESTS OR
     OBLIGATIONS HEREUNDER AND ANY ATTEMPTED SUBLEASE, RELINQUISHMENT,
     ASSIGNMENT, TRANSFER OR ENCUMBERING BY OBLIGOR SHALL BE NULL AND VOID.

          (b) By Obligee. Obligee may, at any time, without notice to, or the
              -----------
     consent of, obligor sell, assign or transfer or grant a security interest
     in all or any part of Obligee's rights, obligations, title or interest in,
     to and under the Equipment or any Item(s) thereof, this Agreement, any
     supplement and/or any Payments and Supplemental Payments payable under this
     Agreement or any Supplement to any leasing or finance company, bank,
     insurance company or other financial institution. Any entity to whom any
     such sale, assignment, transfer or grant of security interest is made is
     herein called an "Assignee" and any such sale, assignment, transfer or
     grant of security interest is herein called an "assignment". An Assignee
     may re-assign and/or grant a security interest in any of such rights,
     obligations, title or interest assigned to such Assignee. Obligor agrees to
     execute such related amendments to this Agreement, such acknowledgments and
     other documents that may be reasonably requested by Obligee or an Assignee
     and that do not, taken as a whole, materially and adversely affect the
     interest of Obligor in the transactions contemplated by this Agreement.
     Each Assignee shall have and may enforce all of the rights and benefits of
     Obligee hereunder with respect to the Item(s) of Equipment and related
     Supplement(s) covered by the assignment, including, without limitation, the
     provisions of Section 8 hereof and Obligor's representations and warranties
     under Section 21 hereof. Each such assignment shall be subject to obligor's
     rights hereunder so long as no Event of Default has occurred and is
     occurring hereunder. Obligor shall be under no obligation to any Assignee
     except upon written notice of such assignment from Obligee or, in the case
     of a reassignment, from the Assignee. Upon written notice to Obligor of any
     such assignment, Obligor agrees to pay the Payments and Supplemental
     Payments with respect to the Item(s) of Equipment covered by such
     assignment to such Assignee in accordance with the instructions specified
     in such notice without any abatement, defense, setoff, counterclaim or
     recoupment whatsoever, and to otherwise comply with all notices, directions
     and demands which may be given by Obligee or such Assignee with respect to
     such Item(s), in accordance with the provisions of this Agreement.
     Notwithstanding any such assignment, all obligations of Obligee to Obligor
     under
<PAGE>

     this Agreement shall be and remain enforceable by Obligor against
     Obligee and any Assignee to whom an assignment hereunder has been made.

     such Item of Equipment has been delivered to Obligee in accordance
     with the provisions of Section 6 hereof or Obligee's interest therein has
     been purchased by Obligor in accordance with the provisions of Section 28
     hereof. Obligor agrees that no occurrence specified in the preceding
     sentence shall impair, in whole or in part, any obligation of Obligor under
     this Agreement, including, without limitation, the obligation to pay
     Payments.

          (b) Payment of Casualty Loss Value Upon an Event of Loss. If an Event
              -----------------------------------------------------
     of Loss occurs with respect to an Item of Equipment during the Term
     thereof, Obligor shall give Obligee prompt written notice thereof and shall
     pay to Obligee on the Casualty Loss Value Payment Date next following the
     date of such Event of Loss (or on the last day of the Term if there is no
     succeeding Casualty Loss Value Payment Date) the sum of (i) all unpaid
     Payments payable for such Item of Equipment for any Payment Period prior to
     the Payment Period in which the Event of Loss has occurred, plus (x) if
     Payments for such Item of Equipment are payable in advance, the Casualty
     Loss Value of such Item of Equipment determined as of the Casualty Loss
     Value Payment Date next preceding or coincident  with the date of such
     Event of Loss, plus the Payments payable for such Item for the Payment
     Period in which such Event of Loss has occurred if such Payment was not
     paid on the Payment Date therefor, or (y) if Payments for such Item are
     payable in arrears, the Casualty Loss Value of such Item of Equipment
     determined as of the Casualty Loss Value Payment Date next following the
     date of such Event of Loss, plus the Payment payable for such Item of
     Equipment for the Payment Period in which such Event of Loss has occurred
     if such Casualty Loss Value Payment Date for such Item is a Payment Date,
     plus (iii) all other Supplemental Payments due for such Item of Equipment
     as of the date of payment of the amounts specified in the foregoing clauses
     (i) and (ii) , for such Item determined as of the Casualty Loss Value
     Payment Date. Any payments received at any time by Obligee or by Obligor
     from any insurer or other party (except Obligor) as a result of the
     occurrence of such Event of Loss will be applied in reduction of Obligor's
     obligation to pay the foregoing amounts, if not already paid by Obligor,
     or, if already paid by Obligor, will be applied to reimburse Obligor for
     its payment of such amount, unless an Event of Default shall have occurred
     and be continuing. Upon payment in full of such Casualty Loss Value,
     Payments and Supplemental Payments, (A) the obligation of Obligor to make
     Payments hereunder with respect to such Item of Equipment shall terminate
     and the Term of such Item shall terminate, and (B) Obligor shall, as agent
     for Obligee, as soon as practicable, dispose of such Item or Items of
     Equipment in a manner reasonably acceptable to Obligee.

          (c) Application of Payments Not Relating to an Event of Loss. Any
              --------------------------------------------------------
     payments (including, without limitation, insurance proceeds) received at
     any time by Obligee or Obligor from any governmental authority or other
     party with respect to any loss or damage to any Item or Items of Equipment
     not constituting an Event of Loss, will be applied directly in payment of
     repairs or for replacement of property in accordance with the provisions of
     Section 11 and 12 hereof, if not already paid by Obligor, or if already
     paid by Obligor and no Event of Default shall have occurred and be
     continuing, shall be applied to reimburse Obligor for such payment, and any
     balance remaining after compliance with the provisions of said Sections
     with respect to such loss or damage shall be retained by Obligor.
<PAGE>

     17.  Insurance.  Obligor will cause to be carried and maintained, at its
          ----------
sole expense, with respect to the Equipment at all times during the Term thereof
and until the Equipment has been delivered to Obligee (a) physical damage
insurance insuring against all risks of physical loss or damage to the
Equipment, in an amount not less than the greater of the Casualty Loss Value of
the Equipment or the replacement value of the Equipment, and (b) comprehensive
insurance against general liability for bodily injury, death and property damage
resulting from the use and operation of the Equipment in an amount not less than
$10,000,000 per occurrence, in each case with exclusions and deductibles
acceptable to Obligee and no greater than those applicable to insurance on
similar equipment owned or operated by Obligor, and (c) contractor's pollution
liability insurance in an amount not less than $7,500,000 per occurrence or such
higher amount as Obligee may, at any time reasonably request, in each case with
exclusions and deductibles acceptable to Obligee and no greater than those
applicable to insurance on similar equipment owned or operated by Obligor. Such
insurance policy or policies will name Obligee and each Assignee as the loss
payees, as their interests may appear, on all policies referred to in clause (a)
of the preceding sentence, and will name Obligee and each Assignee as additional
insureds on all policies referred to in clause (b) of the preceding sentence.
Such policies will provide that the same may not be invalidated against Obligee
or any Assignee by reason of any violation of a condition or breach of warranty
of the policies or the application therefor by Obligor, that the policies may be
cancelled or materially altered or reduced in coverage (except as otherwise
permitted under the terms of this Agreement) by the insurer only after thirty
(30) days, prior written notice to Obligee and each Assignee, and that the
insurer will give written notice to Obligee and each Assignee in the event of
nonpayment of premium by Obligor when due. The policies of insurance required
under this Section shall be valid and enforceable policies issued by insurers of
recognized responsibility acceptable to Obligee and each Assignee and authorized
to do an insurance business in the state in which each Item of Equipment is
located. In the event that any of such policies referred to in clause (b) of the
first sentence of this Section shall now or hereafter provide coverage on a
"claims-made" basis, Obligor shall continue to maintain such policies in effect
for a period of not less than three (3) years after the expiration of the Term
of the last Item of Equipment under this Agreement. Upon the execution of this
Agreement and thereafter not less than thirty (30) days prior to the expiration
dates of any expiring policies theretofore furnished under this Section,
certificates of the insurance coverage required by this Section and, if
requested by Obligee or any Assignee, copies of the policies evidencing such
insurance coverage, shall be delivered by Obligor to Obligee and each other
named loss payee and/or additional insured. Any certificate of insurance issued
with respect to a blanket policy covering other equipment not subject to this
Agreement shall specifically describe the Equipment as being included therein
and covered thereby to the full extent of the coverage's and amounts required
hereunder. If Obligor shall fail to cause the insurance required under this
Section to be carried and maintained, Obligee or any Assignee may provide such
insurance and Obligor shall reimburse Obligee or any such Assignee, as the case
may be, upon demand for the cost thereof as a Supplemental Payment hereunder.

     18.  General Tax Indemnity. Obligor agrees to pay, defend and indemnify and
          -----------------------
hold Obligee, each Assignee and their respective successors and assigns harmless
on an after-tax basis from any and all Federal, state, local and foreign taxes,
fees, withholdings, levies, imposts, duties, assessments
<PAGE>

and charges of any kind and nature whatsoever, together with any penalties,
fines or interest thereon (herein called "taxes or other impositions") howsoever
imposed, whether levied or imposed upon or asserted against Obligee, any
Assignee, Obligor, the Equipment, any Item of Equipment, or any part thereof, by
any Federal, state or local government or taxing authority in the United States,
or by any taxing authority or governmental subdivision of a foreign country,
upon or with respect to (a) the Equipment, or any Item of Equipment or any part
thereof, (b) the manufacture, construction, ordering, purchase, ownership,
delivery, financing, leasing, subleasing, re-leasing, possession, use,
maintenance, registration, re-registration, titling, re-titling, licensing,
documentation, delivery, repossession, sale or other application or disposition
of the Equipment, or any Item of Equipment or any part thereof, (c) the rentals,
receipts or earnings arising from the Equipment or any Item of Equipment or any
part thereof, or (d) this Agreement, each other Obligor Document, the Payments
and/or Supplemental Payments payable by Obligor hereunder and any amounts
payable by Obligor under any other Obligor Document; provided, however, that the
foregoing indemnity shall not apply to any taxes or other impositions based upon
or measured solely by Obligee's or any Assignee's net income, and which are
imposed or levied by any Federal, state or local taxing authority in the United
States. Obligor will promptly notify Obligee of all reports or returns required
to be made with respect to any tax or other imposition with respect to which
Obligor is required to indemnify hereunder, and will promptly provide Obligee
with all information necessary for the making and timely filing of such reports
or returns by Obligee. Obligor will prepare and file the same if permitted by
applicable law to file the same, or if not so permitted, Obligor shall prepare
such reports or returns for signature by Obligee, and shall forward the same,
together with immediately available funds for payment of any tax or other
imposition due, to Obligee, at least ten (10) days in advance of the date such
payment is to be made. Upon written request, Obligor shall furnish Obligee with
copies of all paid receipts or other appropriate evidence of payment for all
taxes or other impositions paid by Obligor pursuant to this Section 18. All of
the indemnities contained in this Section 18 shall continue in full force and
effect notwithstanding the expiration or earlier termination of this Agreement
in whole or in part, including the expiration or termination of the Term with
respect to any Item (or all) of the Equipment, and are expressly made for the
benefit of, and shall be enforceable by, Obligee and each Assignee.

     19.  Indemnification.
          ----------------

          (a) Obligor hereby assumes liability for, and does hereby agree to
     indemnify, protect, save, defend, and hold harmless Obligee, each Assignee,
     and their respective officers, directors, stockholders, successors,
     assigns, agents and servants (each such party being herein, for purposes of
     this Section 19, called an "indemnified party") on an after-tax basis from
     and against any and all obligations, fees, liabilities, losses, damages,
     penalties, claims, demands, actions, suits, judgments, costs and expenses,
     including legal expenses, of every kind and nature whatsoever, imposed on,
     incurred by, or asserted against any indemnified party, in any way relating
     to or arising out of (i) the manufacture, construction, ordering, purchase,
     acceptance or rejection, ownership, titling or retitling, registration or
     re-registration, delivery, financing, leasing, subleasing, re-leasing,
     possession (other than by Obligee or any Assignee), use (other than by
     Obligee or any Assignee), operation (other than by Obligee or any
     Assignee), storage,
<PAGE>

     removal, delivery, return, repossession, sale or other disposition of the
     Equipment or any Item of Equipment, or any part thereof, including, without
     limitation, any of such as may arise from (A) loss or damage to any
     property or death or injury to any persons, (B) patent or latent defects in
     the Equipment (whether or not discoverable by Obligor or any indemnified
     party), (C) any claims based on absolute or strict liability in tort, (D)
     any claims based on patent, trademark, tradename or copyright infringement;
     or (ii) any failure on the part of Obligor to perform or comply with any of
     the terms of this Agreement or any other Obligor Document, and (E) any
     towing charges, parking tolls, fines, parking and speeding tickets,
     odometer certifications and other civil and criminal motor vehicle
     violations with respect to any such Item; and all penalties and interest
     applicable to any of the foregoing, except as set forth in the exception to
     Section 23(a) hereof in the case of any repossession of the Equipment.
     Obligor shall give each indemnified party prompt notice of any occurrence,
     event or condition known to Obligor as a consequence of which any
     indemnified party may be entitled to indemnification hereunder. Obligor
     shall forthwith upon demand of any such indemnified party reimburse such
     indemnified party for amounts expended by it in connection with any of the
     foregoing or pay such amounts directly. Obligor shall be subrogated to an
     indemnified party's rights in any matter with respect to which Obligor has
     actually reimbursed such indemnified party for amounts expended by it or
     has actually paid such amounts directly pursuant to this Section 19. In
     case any action, suit or proceeding is brought against any indemnified
     party in connection with any claim indemnified against hereunder, such
     indemnified party will, promptly after receipt of notice of the
     commencement of such action, suit or proceeding, notify Obligor thereof,
     enclosing a copy of all papers served upon such indemnified party, but
     failure to give such notice or to enclose such papers shall not relieve
     Obligor from any liability hereunder. Obligor may, and upon such
     indemnified party's request will, at Obligor's expense, resist and defend
     such action, suit or proceeding, or cause the same to be resisted or
     defended by counsel selected by Obligor and reasonably satisfactory to such
     indemnified party and in the event of any failure by Obligor to do so,
     Obligor shall pay all costs and expenses (including, without limitation,
     attorney's fees and expenses) incurred by such indemnified party in
     connection with such action, suit or proceeding.

          (b) To the full extent permitted by applicable law, the Obligor hereby
     agrees to defend, indemnify and hold harmless the Obligee, any Assignee and
     each of their respective affiliates and directors, officers, employees and
     agents from and against any and all loss, cost, expense or liability
     (including all costs of legal representation and all fines or penalties)
     incurred in connection with any and all claims or proceedings (whether
     brought by private party or governmental agencies) for bodily injury,
     property damage, abatement or remediation, environmental damage or
     impairment or any other injury or damage resulting from or relating to any
     Hazardous Material located upon or migrating into, from or through the
     property of the Obligor (including without limitation, the Equipment)
     (whether or not the release of such Hazardous Materials was caused by any
     of such Persons, a tenant or subtenant or a prior owner or tenant on any
     such property and whether or not the alleged liability is attributable to
     the handling, storage, generation, remediation, transportation or disposal
     of such substance or the mere presence of the substance on any such
     property), which any such indemnified party may incur due to acquisition of
     its interest in the Equipment, the financing of the Equipment for Obligor,
     the exercise of any of its rights under this Agreement (except, in the
     event of any
<PAGE>

     foreclosure upon and repossession of the Equipment, to the extent caused by
     the gross negligence or willful misconduct of Obligee or its agents), or
     otherwise, including without limitation, any loss, cost, expense or
     liability relating to (i) any Release or threatened Release of any
     Hazardous Material at a Site (other than a release which is permitted
     pursuant to applicable Environmental Laws), (ii) any violation of any
     Environmental Laws with respect to conditions at a Site or the operations
     conducted thereon, or (iii) the investigation or remediation of offsite
     locations at which Obligor or its predecessors are alleged to have directly
     or indirectly Disposed of Hazardous Materials from a Site.

          (c) The provisions of this Section 19, and the obligations of Obligor
     under this Section 19, shall apply from the date of the execution of this
     Agreement notwithstanding that the Term may not have commenced with respect
     to any Item of Equipment, and shall survive and continue in full force and
     effect notwithstanding the expiration or earlier termination of this
     Agreement in whole or in part, including the expiration of termination of
     the Term with respect to any Item (or all) of the Equipment and any
     foreclosure or any modification, release or discharge or any or all of the
     obligations of Obligor under this Agreement, and are expressly made for the
     benefit of, and shall be enforceable by, each indemnified Person.

CLAIM (INCLUDING ANY CLAIM BASED ON STRICT OR ABSOLUTE LIABILITY IN TORT OR
INFRINGEMENT) IT MIGHT HAVE AGAINST OBLIGEE FOR ANY LOSS, DAMAGE (INCLUDING
INCIDENTAL OR CONSEQUENTIAL DAMAGE) OR EXPENSE CAUSED BY THE EQUIPMENT OR BY
OBLIGOR'S LOSS OF USE THEREOF FOR ANY REASON WHATSOEVER, INCLUDING COMPLIANCE
WITH ENVIRONMENTAL LAWS. So long and only so long as an Event of Default shall
not have occurred and be continuing, and so long and only so long as the
Equipment shall be subject to this Agreement and Obligor shall be entitled to
possession of the Equipment hereunder, Obligee authorizes Obligor, at Obligor's
expense, to assert for Obligee's account, all rights and powers of Obligee under
any manufacturer's, vendor's or dealer's warranty on the Equipment or any part
thereof; provided, however, that Obligor shall indemnify, protect, save, defend
and hold harmless Obligee from and against any and all claims, and all costs,
expenses, damages, losses and liabilities incurred or suffered by Obligee in
connection therewith, as a result of, or incident to, any action by Obligor
pursuant to the foregoing authorization.

respect of, any Federal, state, local or foreign government or governmental
authority or agency or any other Person, other than the filings referred to in
Section 26 of this Agreement, or if required, such consent has been obtained and
forwarded to Obligee; (f) no mortgage, deed of trust, or other Lien which now

litigation or other proceeding now pending or, to the best of Obligor's
knowledge, threatened, against or affecting the Obligor, in any court or before
any regulatory commission, board or other administrative governmental agency
which would directly or indirectly adversely affect or impair obligee's rights
and security interest in and to the Equipment, or which, if decided adversely to
Obligor, would have a material adverse effect on the financial condition or

faith and by appropriate proceedings; (1) (i) without limiting the generality of
the foregoing, the retention of possession by Obligor of any Item of Equipment
to be subject to this Equipment Agreement, following the transfer of an interest
therein to Obligee, shall not be deemed fraudulent or void as against any
present or future creditor of the Obligor under the laws of the states where
such Item will, at the time of such transfer of an interest, be located, nor

event of any attempted subsequent sale thereof by the obligor, acquire any title
to or rights therein superior to Obligee's interest and rights therein, and (ii)
payment in full has been made by Obligor for each Item of Equipment to the

          (i) there shall have occurred any event which, in the reasonable
     judgment of the obligee, has had a material adverse effect on the
     properties, executive management (taken as a whole), condition (financial
     or otherwise), operations or business of the Obligor taken as a whole or of
     Guarantor taken as a whole, or in Obligee's reasonable opinion, Obligee's
     interest in the Equipment is materially impaired; or

          (j) the Guarantor shall repudiate or contest the enforceability of the
     Guaranty, or the Guaranty shall be unenforceable in whole or in part, or

          ----------------------
at any time thereafter so long as the same shall be continuing, Obligee may
exercise one or more of the following remedies as Obligee in its sole discretion
shall elect:

          (a) Obligee may terminate or cancel this Agreement, without prejudice
     to any other remedies of Obligee hereunder, with respect to all or any Item
     of Equipment, and whether or not this Agreement has been so terminated or
     cancelled, may enter the premises of Obligor or any other party to take
     immediate possession of the Equipment and remove all or any Item of
     Equipment by summary proceedings or otherwise, or may cause Obligor, at
     Obligor's expense, to store, maintain, surrender and deliver possession of
     the Equipment or such Item in the same manner as provided in Section 6
     hereof, all without liability to Obligee for or by reason of such entry or
     taking of possession, whether for the restoration of damage to property
     caused by such taking or otherwise, except to the extent caused by the
     gross negligence or willful misconduct of Obligee or its agents;

          (b) Obligee may hold, keep idle or lease to others the Equipment or
     any Item of Equipment, as Obligee in its sole discretion may determine,
     free and clear of any rights of Obligor and without any duty to account to
     Obligor with respect to such action or inaction or for any proceeds with
     respect thereto, except that Obligor's obligation to make Payments for any
     Payment Periods commencing after Obligor shall have been deprived of
     possession pursuant to this Section 23 shall be reduced by the net
     proceeds, if any, received by Obligee from leasing the Equipment or such
     Item to any Person other than Obligor for the same Payment Periods or any
     portion thereof;

          (c) Obligee may sell the Equipment or any Item of Equipment at public

     Equipment or Item(s) so sold for any Payment Period commencing after the
     date on which such sale occurs), the sum of (i) all unpaid Payments payable
     for each Item of Equipment for all Payment Periods through the date on
     which such sale occurs, plus (ii) an amount equal to the excess, if any, of
     (x) the Casualty Loss Value of the Equipment or Item(s) so sold, computed
     as of the Payment Date coincident with or next preceding the date of such
     sale, over (y) the net
<PAGE>

     proceeds of such sale, plus interest at the rate specified in Section 25
     hereof on the amount of such excess from the Payment Date as of which such
     Casualty Loss Value is computed until the date of actual payment, plus
     (iii) all unpaid Supplemental Payments due with respect to each Item of
     Equipment so sold, including a Reinvestment Premium, computed as of the
     Payment Date coincident with or next preceding the date of such sale; and

          (d)    whether or not Obligee shall have exercised, or shall
     thereafter at any time exercise, any of its rights under subsection (a) or
     (b) above with respect to any Item(s) of Equipment, Obligee, by written
     notice to Obligor specifying a payment date, may demand that Obligor pay to
     Obligee, and Obligor shall pay to Obligee, on the payment date specified in
     such notice, as liquidated damages for loss of a bargain and not as a
     penalty (in lieu of the Payments due for any Item(s) of Equipment for   any
     Payment Period commencing after the payment date specified in such notice
     and in lieu of the exercise by Obligee of its remedies under subsection (b)
     above in the case of a release of such Item(s) or under subsection (c)
     above with respect to a sale of such Item (s), the sum of (i) all unpaid
     Payments payable for such Item (s) for all Payment Periods through the
     payment date specified in such notice, plus (ii) all unpaid Supplemental
     Payments due with respect to such Item(s) as of the payment date specified
     in such notice, including a Reinvestment Premium computed as of the payment
     date specified in such notice, plus (iii) an amount, with respect to each
     such Item, equal to the Casualty Loss Value of such Item(s) computed as of
     the Payment Date coincident with or next preceding the payment date
     specified in such notice; provided, however, that in the event of a sale of
     any such Item(s) delivered to or repossessed  by Obligee, if Obligor has
     paid in full the amounts described in this paragraph Obligee shall refund
     to Obligor the aggregate Net Proceeds of Sale of such Item(s) of Equipment
     as defined in Section 29 (d)(ii) ; and

          (e)    Obligee may exercise any other right or remedy which may be
     available to it under applicable law or proceed by appropriate court action
     to enforce the terms hereof or to recover damages for the breach hereof or
     to rescind this Agreement.

     At any sale pursuant to this Section 23, the purchaser shall take the
Equipment free and clear of all rights and interest of Obligor in the Equipment.

     In addition, Obligor shall be liable for all costs and expenses, including
attorney's fees, incurred by Obligee or any Assignee by reason of the occurrence
of any Event of Default or the exercise of obligee's remedies with respect
thereto, including all costs and expenses incurred in connection with the
delivery of the Equipment in accordance with Section 6 hereof or in placing the
Equipment in the condition required by said Section including, without
limitation, decontamination expenses. Except as otherwise expressly provided
above, no remedy referred to in this Section 23 is intended to be exclusive, but
each shall be cumulative and in addition to any other remedy referred to above
or otherwise available to Obligee at law or in equity; and the exercise or
beginning of exercise by Obligee of any one or more of such remedies shall not
constitute the exclusive election of such remedies and shall not preclude the
simultaneous or later exercise by Obligee of any or all of such other remedies.
No express or implied waiver by obligee of any Event of Default shall in any way
be, or be construed to be, a waiver of any future
<PAGE>

or subsequent Event of Default. To the extent permitted by applicable law,
Obligor hereby waives any rights now or hereafter conferred by statute or
otherwise which may require obligee to sell, lease or otherwise use the
Equipment in mitigation of Obligee's damages as set forth in this Section or
which may otherwise limit or modify any of Obligee's rights and remedies in this
Section 23.

     24.  Obligee's Right to Perform for Obligor.  If Obligor fails to make any
          ---------------------------------------
Supplemental Payment required to be made by it hereunder or fails to perform
or comply with any of its agreements contained herein, Obligee may itself, after
notice to obligor, make such payment or perform or comply with such agreement,
and the amount of such payment and the amount of the reasonable expenses of
Obligee incurred in connection with such payment or the performance of or
compliance with such agreement, as the case may be, together with interest
thereon at the rate specified in Section 25 hereof, shall, if not paid by
Obligor to Obligee on demand, be deemed a Supplemental Payment hereunder;
provided, however, that no such payment, performance or compliance by Obligee
-------------------
shall be deemed to cure any Event of Default hereunder.

     25.  Late Charges.  Obligor shall pay to Obligee, upon demand interest on
          -------------
any Payment not paid when due, and on any Supplemental Payment or other amount
payable under this Agreement which is not paid when due, for any period for
which any of the same is overdue (without regard to any grace period) at a rate
equal to the lesser of (a) nine and 76/100 percent (9.76%) per annum, or (b) the
maximum rate of interest permitted by law.

     26.  Further Assurances.  Obligor will promptly and duly execute and
          -------------------
deliver to Obligee and any Assignee such other documents and assurances,
including, without limitation, such amendments to this Agreement as may be
reasonably required by Obligee and by any Assignee, and Uniform Commercial Code
financing statements and continuation statements (it being understood and agreed
that such financing statements and continuation statements will not be requested
for a jurisdiction other than those in which the chief executive office of the
Obligor is located or a jurisdiction in which a mobile filter press is located),
and will take such further action as Obligee or any Assignee may from time to
time reasonably request in order to carry out more effectively the intent and
purposes of this Agreement and to establish and protect the rights and remedies
created or intended to be created in favor of Obligee and of any Assignee and
their respective rights and interests in and to the Equipment.

     27.  Notices.  All notices provided for or required under the terms and
          --------
provisions hereof shall be in writing, and any such notice shall be deemed given
when personally delivered or when deposited in the United States mails, with
proper postage prepaid, for first class certified mail, return receipt
requested, addressed (i) if to Obligee or Obligor, at their respective addresses
as set  forth herein or at such other address as either of them shall, from time
to time, designate in writing to the other, and (ii) if to any Assignee, to the
address of such Assignee as such Assignee shall designate in writing to Obligee

     28.  Obligor's Renewal and Purchase Options; Third Party Sale.
          ---------------------------------------------------------

          (a) Obligor's Renewal Option. If (i) no Event of Default shall have
              --------------------------
     occurred and be continuing and (ii) this Agreement shall not have been
     earlier terminated, Obligor shall be entitled, at its option, to renew this
     Agreement with respect to all, but not less than all, Items of Equipment
     then subject to this Agreement for the Renewal Term(s) specified on the
     Related Exhibit A for such Item. The first Renewal Term with respect to
     each such Item of Equipment will commence at the expiration of the Basic
     Term of such Item, and each succeeding Renewal Term will commence at the
     expiration of the next preceding Renewal Term. All of the provisions of
     this Agreement shall be applicable during each Renewal Term for each such
     Item of Equipment, except that Payments during each Renewal Term shall be
     payable at the times and on the Payment Dates set forth on said Related
     Exhibit A. If Obligor intends not to exercise said renewal option with
     respect to any of said Renewal Terms, Obligor shall give written notice to
     Obligee to such effect at least one hundred eighty (180) days prior to the
     expiration of the Basic Term of the Item(s) of Equipment whose Basic Term
     first expires hereunder, in the case of the first Renewal Term, and at
     least one hundred eighty (180) days prior to the expiration of the then
     current Renewal Term of the Item(s) of Equipment whose Basic Term first
     expires hereunder, in the case of the then next succeeding Renewal Term. If
     Obligor fails to give such written notice to Obligee with respect to any of
     said Renewal Terms, it shall be conclusively presumed that Obligor has
     elected to exercise said renewal option with respect to said Renewal Term.
     In the event Obligor elects not to exercise said renewal option (unless
     Obligee has otherwise agreed in writing or Obligor has exercised its
     purchase option under Section 28(b) hereof) each such Item of Equipment
     shall be delivered to Obligee in accordance with the provisions of Section
     6(a) hereof (unless delivered to a bidder in accordance with Section 28(c)
     hereof) and until each such Item has been so delivered Obligor shall
     continue to pay Obligee the Payments for each such Item as specified in
     Section 6(b) hereof.

          (b) Obligor's Purchase Option. If (i) no Event of Default shall have
              ---------------------------
     occurred and be continuing, and (ii) this Agreement shall not have been
     earlier terminated, Obligor shall be entitled, at its option, upon written
     notice to Obligee, as hereinafter provided, to purchase Obligee's interest
     in all, but not less than all, Items of Equipment then subject to this
     Agreement, on the Termination Date for each such Item of Equipment, for an
     amount (the "Purchase Option Amount"), with respect to each Item of
     Equipment, payable in immediately available funds, equal to the sum of (w)
     the Estimated Residual Value of such Item of Equipment applicable to the
     Basic Term or Renewal Term thereof then ending, plus W the Payments due and
     payable for such Item of Equipment on the Termination Date, if Payments for
     such Item are payable in arrears, plus (y) any applicable sales, excise or
     other taxes imposed as a result of such sale (other than gross or net
     income taxes attributable to such sale), plus (2) any Supplemental Payments
     then due and owing to Obligee hereunder including, in the event that
     Obligor exercises its purchase option hereunder prior to the end of the
     Maximum Term, the Reinvestment Premium. Obligee's sale of its interest in
     each Item of Equipment shall be on an as-is, where-is basis, without any
     representation or warranty by, or recourse to, Obligee. If Obligor intends
     to exercise said purchase option, Obligor shall give written notice to
     obligee to such effect at least one hundred eighty (180) days prior to the
     expiration of the Basic Term of the Item(s) of Equipment whose Basic Term
     first expires hereunder, or, if Obligor has renewed this Agreement pursuant
     to Section 28(a) hereof, then at least one hundred
<PAGE>

     eighty (180) days prior to the expiration of the then current Renewal Term
     of the Item(s) of Equipment whose Basic Term first expires hereunder. If
     Obligor gives such written notice to Obligee same shall constitute a
     binding obligation of Obligor to purchase Obligee's interest in all of such
     Items of Equipment and to pay Obligee the Purchase Option Amount on the
     Termination Date thereof.

          (c)  Third Party Sale of Equipment.
               ------------------------------

               (i) Remarketing Obligations. In the event Obligor does not
                   -------------------------
          exercise either its option to renew this Agreement or to purchase
          Obligee's interest in the Equipment pursuant to this Section, then
          Obligor shall have the obligation during the last one hundred eighty
          (180) days of the Basic Term, or the then current Renewal Term, if
          applicable (the "Remarketing Period"), to obtain bona fide bids for
          Obligee's interest in not less than all Items of Equipment then
          subject to this Agreement from prospective purchasers who are
          financially capable of purchasing such interest for cash on an as-is,
          where-is basis, without recourse or warranty. All bids received by
          Obligor prior to the end of the Basic Term, or Renewal Term if
          applicable, of such Item(s) of Equipment shall be immediately
          certified to Obligee in writing, setting forth the amount of such bid
          and the name and address of the person or entity submitting such bid.
          Notwithstanding the foregoing, Obligee shall have the right, but not
          the obligation, to seek bids for its interest in the Equipment during
          the Remarketing Period.

               (ii) Sale of Obligee's Interest in the Equipment to Third Party
                    ----------------------------------------------------------
          Buyer.  on the Termination Date, provided that all the conditions
          ------
          hereof have been met, Obligee shall sell (or cause to be sold) its
          interest in all Items of Equipment then subject to this Agreement, for
          cash to the bidder, if any, who shall have submitted the highest bid
          during the Remarketing Period on an as-is, where-is basis and without
          recourse or warranty, and upon receipt by Obligee of the sales price
          Obligee shall instruct Obligor to deliver and Obligor shall deliver
          such Item(s) of Equipment to such bidder; provided, that (x) any such
          sale to a third party shall be consummated, and the sales price for
          Obligee's interest in such Item shall be paid to Obligee in
          immediately available funds, on or before the Termination Date; and
          (y) Obligee shall not be obligated to sell its interest in such
          Equipment (I) if the Net Proceeds of Sale of its interest in such
          Item(s) is less than the aggregate Maximum Obligee Risk Amount
          applicable to such Item(s) as of the Termination Date or (II) if
          Obligee has not received the amounts, if any, payable by Obligor
          pursuant to Section 29(a) and, if applicable, Section 29(c). Such
          third party purchaser shall take the Equipment free and clear of all
          rights and interest of Obligor in the Equipment.

     29.  End of Term Adjustment.
          -----------------------

          (a) Third Party Sale of Equipment. This Section 29(a) shall apply

     interest in such Item(s) to a third party pursuant to
<PAGE>

     Section 28(c) hereof has been consummated on the Termination Date. If the
     Net Proceeds of Sale of Obligee's interest in such Item(s) is less than the
     aggregate Estimated Residual Value of such Item(s) as of such Termination
     Date, Obligor shall, on the Termination Date, pay to Obligee as an End of
     Term Adjustment, in immediately available funds, an amount equal to such
     deficiency (a "Deficiency") as an adjustment to the Payments payable under
     this Agreement for such Item, plus the Payments due and payable for such
     Item(s) of Equipment on the Termination Date, if Payments for such Item(s)
     are payable in arrears, plus any Supplemental Payments then due and owing
     to Obligee hereunder; provided, however, that if no Event of Default or
                           -----------------
     event which, with notice or passage of time or both would constitute an
     Event of Default, shall have occurred and be continuing hereunder, the
     amount of the Deficiency payable by Obligor with respect to such Item(s)
     shall not exceed the aggregate Maximum Obligor Risk Amount then applicable
     to such Item(s). If the Net Proceeds of Sale of such Item(s) of Equipment
     exceeds the aggregate Estimated Residual Value of such Item(s) and if no
     Event of Default or event which, with notice or passage of time or both
     would constitute an Event of Default, shall have occurred and be continuing
     hereunder and Obligor shall have paid Obligee on or before the Termination

     Obligor an amount equal to such excess as an adjustment to the Payments
     payable under this Agreement for such Item(s).

          (b) Obligor Payment.  If a sale of Obligee's interest in all Items
              ----------------
     of Equipment then subject to this Agreement either to the Obligor pursuant
     to Section 28(b) hereof or to a third party pursuant to Section 28(c)
     hereof has not been consummated on the Termination Date with respect
     thereto for any reason, then the Obligor shall, on the Termination Date of
     such Items, pay to Obligee as an End of Term Adjustment, in immediately
     available funds, as an adjustment to the Payments payable under this
     Agreement for such Items, an amount equal to (i) the Maximum Obligor Risk
     Amount of all of such Items, if on the Termination Date no Event of Default
     or event which, with notice or passage of time or both would constitute an
     Event of Default, shall have occurred and be continuing hereunder, or (ii)
     the Estimated Residual Value of all of such Items, if on the Termination
     Date an Event of Default or event which, with notice or passage of time or
     both would constitute an Event of Default, shall have occurred and be
     continuing hereunder, plus, in either case, the Payments due and payable
     for such Item(s) of Equipment on the Termination Date, if Payments for such
     Item(s) are payable in arrears, plus all Supplemental Payments then due and

     Obligor shall pay, or reimburse Obligee for the payment of, any applicable
     sales, excise or other taxes imposed as a result of such sale, other than
     gross or net income taxes attributable to such sale, and such obligation
     shall survive the termination of this Agreement.

          (c) Reinvestment Premium. In the event a Termination Date of any Item
              ----------------------
     of Equipment occurs prior to the last day of the Maximum Term hereof
     relating to such Item, Obligor shall pay to
<PAGE>

     Obligee on the Termination Date of such Item in immediately available
     funds, in addition to any other obligations hereunder, the Reinvestment
     Premium relating to such Item.

continuing, Obligee shall take no action inconsistent with such ownership for
income tax purposes.

     33.  Voluntary Termination for Obsolescence. So long as no Event of
          ---------------------------------------
Default shall have occurred and be continuing hereunder, Obligor shall have the
right at its option on any Payment Date during the Basic Term or any Renewal
Term, on at least ninety (90) days, prior written notice to and with the prior
written consent of Obligee (not to be unreasonably withheld), to terminate this
Equipment Agreement with respect to any Item of Equipment then subject to this
Agreement if, in Obligor's good faith opinion, as evidenced by a certificate of
its President, treasurer or chief financial officer, such Item shall have become
no longer useful, or surplus, to Obligor in its business, with such termination
to be effective on the Payment Date specified in such notice (for purposes of
this Section 33, called the "termination date"). During the period from the
giving of such notice until the date thirty (30) days prior to the termination
date, Obligor, as agent for Obligee, shall use its reasonable efforts (but no
less effort than used to sell equipment Obligor owns itself) to secure the
highest obtainable bids for the purchase of Obligee's interest in such Item and
in the event it receives any bid during such period, Obligor shall promptly
certify to Obligee in writing the amount and terms of such bid and the name and
address of the party submitting such bid on the termination date (but in no
event prior to Obligee's receipt of the amounts specified in the next succeeding
sentence), Obligor shall deliver possession of such Item to the bidder, if any,
which shall have submitted the highest bid during such period, and Obligee
shall, without recourse or warranty, simultaneously therewith transfer its
interest in such Item on an "as-is", "where-is" basis for cash to such bidder.
The total transfer price realized at such sale shall be paid to and retained by
Obligee and, in addition, on the
<PAGE>

termination date Obligor shall pay to Obligee the sum of the amounts specified
in sub-clauses (i) through (v): (i) the Payments due and payable for such Item
on the termination date, plus (ii) all accrued and unpaid Payments owing for
such Item for all Payment Periods prior to the Payment Period for which the
Payments specified in the preceding sub-clause (i) is payable, plus (iii) the
excess, if any, of the Termination Value of such Item as of the Payment Date
coincident with the termination date, over the aggregate proceeds of sale of
Obligee's interest in such Item, after deducting from such proceeds of sale the
expenses incurred by Obligee in connection with such sale, plus (iv) any sales
or excise taxes on or measured by such sale, plus (v) all accrued and unpaid
Supplemental Payments owing by Obligor as of the termination date, including a
Reinvestment Premium for such Item determined as of such termination date.
Neither Obligor nor any person, firm or corporation, affiliated with Obligor,
may purchase the Equipment, or after any such sale, lease or otherwise utilize
the Equipment. If no sale shall have occurred on or as of the termination date
this Equipment Agreement (including the provisions of this Section 33 shall
continue in full force and effect with respect to the Equipment. In the event of
any such sale and the receipt by Obligee of the amounts described above, and
upon compliance by Obligor with the provisions of this Section 33, the
obligations of Obligor to make Payments hereunder with respect to each item of
Equipment so sold shall cease for any Payment Period that commences on or after
the termination date and the Term with respect to each such Item of Equipment
shall end effective as of the termination date. Obligee may, but shall be under
no duty to, solicit bids, inquire into the efforts of Obligor to obtain bids or
otherwise take any action in connection with any such sale other than the duty
to transfer to the purchaser named in the highest bid certified by Obligor to
Obligee, without recourse or warranty, on an "as-is", "where-is" basis, all of
Obligee's interest in and to the Equipment so sold against receipt by Obligee of
the payments provided for herein. Anything herein to the contrary
notwithstanding, if Obligor shall exercise its said right to termination as
provided in this Section 33, Obligee may, in its sole discretion, elect to
receive delivery of all of the Equipment subject to said notice by giving
Obligor written notice to such effect within thirty (30) days following
Obligee's receipt of the written notice from Obligor hereinabove provided, in
which event (a) no sale shall occur pursuant to this Section 33, (b) Obligor
shall deliver the Equipment to Obligee in accordance with the provisions of
Section 6 hereof and shall continue to make Payments for the Equipment on each
Payment Date to and inclusive of (and the Term of the Equipment shall terminate
on) the Payment Date next following the date on which such delivery occurs.

        34.    No Reliance. Obligor hereby acknowledges that in negotiating the
               -- ---------

sought, obtained and relied exclusively upon such accounting, actuarial, tax and

parent, subsidiaries, affiliates or personnel has represented or warranted the
legal, tax economic, accounting, or other consequences of the terms and
provisions hereof and of the other related agreements and documents.

as to such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating or

each other Obligor Document shall be binding upon and shall inure to the benefit
of the respective successors and assigns of Obligee and (subject to the
restrictions of Section 14(a) hereof) Obligor. This Agreement and the other
Obligor Documents collectively constitute the complete and exclusive statement
of the terms of the agreement between Obligee and Obligor with respect to the
financing of the Equipment, and cancel and supersede any and all prior oral or
