attorney-in-fact unless Lessee is in default. Lessee shall pay any reasonable
expenses of Lessor in adjusting or collecting insurance. Lessee will not make
adjustments with insurers except with respect to claims for damage to any unit
of Equipment where the repair costs are less than the lesser of ten percent
(10%) of the original Equipment cost or ten thousand and 00/100 dollars
($10,000). Unless a default has occurred and is continuing hereunder, Lessee
may, at its option, apply proceeds of insurance, in whole or in part, to (i)
repair or replace Equipment or any portion thereof, or (ii) satisfy any
obligation of Lessee to Lessor under this Agreement.

9.     RETURN OF EQUIPMENT:

       (a) At the expiration or termination of this Agreement or any Schedule,
Lessee shall perform any testing and repairs required to place the units of
Equipment in the same condition and appearance as when received by Lessee
(reasonable wear and tear excepted) and in good working order for the original
intended purpose of the Equipment. If required the units of Equipment shall be
deinstalled, disassembled and crated by an authorized manufacturer's
representative or such other service person as is reasonably satisfactory to
Lessor. Lessee shall remove installed markings that are not necessary for the
operation, maintenance or repair of the Equipment. All Equipment will be
cleaned, cosmetically acceptable, and in such condition as to be immediately
installed into use in a similar environment for which the Equipment was
originally intended to be used. All waste material and fluid must be removed
from the Equipment and disposed of in accordance with then current waste
disposal laws. Lessee shall return the units of Equipment to a location within
the continental United States as Lessor shall direct. Lessee shall obtain and
pay for a policy of transit insurance for the redelivery period in an amount
equal to the replacement value of the Equipment. The transit insurance must name
Lessor as the loss payee. The Lessee shall pay for all costs to comply with this
section (a).

       (b) Until Lessee has fully complied with the requirements of Section 9(a)
above, Lessee's rent payment obligation and all other obligations under this
Agreement shall continue from month to month notwithstanding any expiration or
termination of the lease term. After expiration or termination of the lease term
Lessor may terminate the Lessee's right to use the Equipment upon ten (10) days
notice to Lessee.

       (c) Unless Lessee exercises its end of lease purchase option contained in
Section 19 below, upon expiration or termination of the lease term, Lessee shall
provide to Lessor a detailed inventory of all components of the Equipment
including model and serial numbers, and Lessee shall also provide an up-to-date
copy of all other documentation pertaining to the Equipment. Unless Lessee
exercises its end of lease purchase option contained in Section 19 below All

Section 19 below Lessee shall make the Equipment available for on-site
operational inspections by potential purchasers at least one hundred twenty
(120) days prior to and continuing up to lease termination. Lessor shall provide
Lessee with reasonable notice prior to any inspection. Lessee shall provide
personnel, power and other requirements necessary to demonstrate electrical,
hydraulic and mechanical systems for each item of Equipment.

10.    DEFAULT AND REMEDIES:

       (a) Lessor may in writing declare this Agreement in default if: (i)
Lessee breaches its obligation to pay rent or any other sum when due and payable
hereunder and fails to cure the breach within ten (10) days; (ii) Lessee
breaches any of its insurance obligations under Section 8; (iii) Lessee breaches
any of its other obligations hereunder and fails to cure that breach within
thirty (30) days after written notice from Lessor, (iv) any representation or
warranty made by Lessee in connection with this Agreement shall be false or
misleading in any material respect when made, (v) Lessee or any guarantor or
other obligor for the Lessee's obligations hereunder ("GUARANTOR") becomes
insolvent or ceases to do business as a going concern, (vi) any Equipment is
illegally used; (vii) if Lessee or any Guarantor is a natural person, any death
or incompetency of Lessee or such Guarantor; or (viii) a petition is filed by or
against Lessee or any Guarantor under any bankruptcy or insolvency laws and in
the event of an involuntary petition, the petition is not dismissed within
forty-five (45) days of the filing date. The default declaration shall apply to
all Schedules unless specifically excepted by Lessor.

       (b) After a default, at the request of Lessor, Lessee shall comply with
the provisions of Section 9(a). Lessee hereby authorizes Lessor to peacefully
enter any premises where any Equipment may be and take possession of the
Equipment. Lessee shall immediately pay to Lessor without further demand as
liquidated damages for loss of a bargain and not as a penalty, the Stipulated
Loss Value of the Equipment (calculated as of the rent payment date prior to the
declaration of default), and all rents and other sums then due under this
Agreement and all Schedules. Lessor may terminate this Agreement as to any or
all of the Equipment. A termination shall occur only upon written notice by
Lessor to Lessee and only as to the units of Equipment specified in any such
notice. Lessor may, but shall not be required to, sell Equipment at private or
public sale, in bulk or in parcels, with or without notice, and without having
the Equipment present at the place of sale. Lessor may also, but shall not be
required to, lease, otherwise dispose of or keep idle all or part of the
Equipment. Lessor may use Lessee's premises for a reasonable period of time for
any or all of the purposes stated above without liability for rent, costs,
damages or otherwise. The proceeds of sale, lease or other disposition, if any,
shall be applied in the following order of priorities: (i) to pay all of
Lessor's reasonable costs, charges and expenses incurred in taking, removing,
holding, repairing and selling, leasing or otherwise disposing of Equipment,
then, (ii) to the extent not previously paid by Lessee, to pay Lessor all sums
due from Lessee under this Agreement, then (iii) to reimburse to Lessee any sums


<PAGE>   4

previously paid by Lessee as liquidated damages; and then (iv) to Lessee, if
there exists any surplus. Lessee shall immediately pay any deficiency in (i) and
(ii) above.

       (c) The foregoing remedies are cumulative, and any or all thereof may be
exercised instead of or in addition to each other or any remedies at law, in
equity, or under statute. Lessee waives notice of sale or other disposition (and
the time and place thereof), and the manner and place of any advertising. Lessee
shall pay Lessor's actual reasonable attorney's fees incurred in connection with
the enforcement, assertion, defense or preservation of Lessor's rights and
remedies under this Agreement, or if prohibited by law, such lesser sum as may
be permitted. Waiver of any default shall not be a waiver of any other or
subsequent default.

       (d) Any default under the terms of this or any other agreement between
Lessor and Lessee may be declared by Lessor a default under this and any such
other agreement.

11.    ASSIGNMENT: LESSEE SHALL NOT SELL, TRANSFER, ASSIGN, ENCUMBER OR SUBLET
ANY EQUIPMENT OR THE INTEREST OF LESSEE IN THE EQUIPMENT WITHOUT THE PRIOR

Schedule to such assignee or as instructed by Lessor. Lessee also agrees to
confirm in writing receipt of the notice of assignment as may be reasonably
requested by assignee. Lessee hereby waives and agrees not to assert against any
such assignee any defense, set-off, recoupment claim or counterclaim which
Lessee has or may at any time have against Lessor for any reason whatsoever.

12.    NET LEASE: Lessee is unconditionally obligated to pay all rent and other
amounts due for the entire lease term no matter what happens, even if the
Equipment is damaged or destroyed, if it is defective or if Lessee no longer can
use it. Lessee is not entitled to reduce or set-off against rent or other
amounts due to Lessor or to anyone to whom Lessor assigns this Agreement or any
Schedule whether Lessees clam arises out of this Agreement, any Schedule, any
statement by Lessor, Lessors liability or any manufacturers liability, strict
liability, negligence or otherwise.

13.    INDEMNIFICATION:

       (a) Lessee hereby agrees to indemnify Lessor, its agents, employees,
successors and assigns (on an after tax basis) from and against any and all
losses, damages, penalties, injuries, claims, actions and suits, including
reasonable legal expenses, of whatsoever kind and nature arising out of or
relating to the Equipment or this Agreement, except to the extent the losses,
damages, penalties, injuries, claims, actions, suits or expenses result from
Lessors gross negligence or willful misconduct ("CLAIMS"). This indemnity shall
include, but is not limited to, Lessor's strict liability in tort and Claims,
arising out of (i) the selection, manufacture, purchase, acceptance or rejection

       (b) All of Lessor's rights, privileges and indemnities contained in this
Section 13 shall survive the expiration or other termination of this Agreement.
The rights, privileges and indemnities contained herein are expressly made for
the benefit of, and shall be enforceable by Lessor, its successors and assigns.

14. DISCLAIMER: LESSEE ACKNOWLEDGES THAT IT HAS SELECTED THE EQUIPMENT WITHOUT
ANY ASSISTANCE FROM LESSOR, ITS AGENTS OR EMPLOYEES. LESSOR DOES NOT MAKE, HAS
NOT MADE, NOR SHALL BE DEEMED TO MAKE OR HAVE MADE, ANY WARRANTY OR
REPRESENTATION, EITHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, WITH RESPECT TO THE
EQUIPMENT LEASED UNDER THIS AGREEMENT OR ANY COMPONENT THEREOF, INCLUDING,

present business and operations, including the jurisdictions) where the
Equipment is or is to be located.

       (b) The Documents have been duly authorized, executed and delivered by

any governmental authority or entity with respect to the entry into or
performance by Lessee of the Documents except such as have already been
obtained.

       (d) The entry into and performance by Lessee of the Documents will not:
(i) violate any judgment, order, law or regulation applicable to Lessee or any
provision of Lessee's Certificate of Incorporation or bylaws; or (ii) result in
any breach of, constitute a default under or result in the creation of any lien,
charge, security interest or other encumbrance upon any Equipment pursuant to
any indenture, mortgage, deed of trust, bank loan or credit agreement or other
instrument (other than this Agreement) to which Lessee is a party.

       (e) There are no suits or proceedings pending or threatened in court or

Lessee, which if decided against Lessee will have a material adverse effect on
the ability of Lessee to fulfill its obligations under this Agreement.

       (f) The Equipment accepted under any Certificate of Acceptance is and
will remain tangible personal property.

       (g) Each financial statement delivered to Lessor has been prepared in

or otherwise) of the Lessee.

       (h) Lessee is and will be at all times validly existing and in good
standing under the laws of the State of its incorporation (specified in the
first sentence of this Agreement).

       (i) The Equipment will at all times be used for commercial or business
purposes.

16.    OWNERSHIP FOR TAX PURPOSES, GRANT OF SECURITY INTEREST; USURY SAVINGS:

       (a) For income tax purposes, the parties hereto agree that it is their
mutual intention that Lessee shall be considered the owner of the Equipment.
Accordingly, Lessor agrees (i) to treat Lessee as the owner of the Equipment on
its federal income tax return, (ii) not to take actions or positions
inconsistent with such treatment on or with respect to its federal income tax
return, and (iii) not to claim any tax benefits available to an owner of the
Equipment on or with respect to its federal income tax return. The foregoing
undertakings by Lessor shall not be violated by Lessor's taking a tax position
inconsistent with the foregoing sentence to the extent such a position is
required by law or is taken through inadvertence so long as such inadvertent tax
position is reversed by Lessor promptly upon its discovery. Lessor shall in no
event be liable to Lessee if Lessee fails to secure any of the tax benefits
available to the owner of the Equipment.

       (b) Lessee hereby grants to Lessor a first security interest in the
Equipment, together with all additions, attachments, accessions, accessories and
accessions thereto whether or not furnished by the Supplier of the Equipment and
any and all substitutions, replacements or exchanges therefor, and any and all
insurance and/or other proceeds of the property in and against which a security
interest is granted hereunder. Notwithstanding anything to the contrary
contained elsewhere in this Agreement, to the extent that Lessor asserts a
purchase money security interest in any items of Equipment ("PMSI EQUIPMENT"):
(i) the PMSI Equipment shall secure only those sums which have been advanced by
Lessor for the purchase of the PMSI Equipment, or the acquisition of rights
therein, or the use thereof (the "PMSI INDEBTEDNESS"), and (ii) no other
Equipment shall secure the PMSI Indebtedness.

       (c) It is the intention of the parties hereto to comply with any
applicable usury laws to the extent that any Schedule is determined to be
subject to such laws; accordingly, it is agreed that, notwithstanding any
provision to the contrary in any Schedule or this Agreement, in no event shall
any Schedule require the payment or permit the collection of interest in excess
of the maximum amount permitted by applicable law. If any such excess interest
is contracted for, charged or received under any Schedule or this Agreement, or
in the event that all of the principal balance shall be prepaid, so that under
any of such circumstances the amount of interest contracted for, charged or
received under any Schedule or this Agreement shall exceed the maximum amount of
interest permitted by applicable law, then in such event (i) the provisions of
this paragraph shall govern and control, (ii) neither Lessee nor any other
person or entity now or hereafter liable for the payment hereof shall be
obligated to pay the amount of such interest to the extent that it is in excess
of the maximum amount of interest permitted by applicable law, (iii) any such
excess which may have been collected shall be either applied as a credit against
the then unpaid principal balance or refunded to Lessee, at the option of the
Lessor, and (iv) the effective rate of interest shall be automatically reduced
to the maximum lawful contract rate allowed under applicable law as now or
hereafter construed by the courts having jurisdiction thereof. It is further
agreed that without limitation of the foregoing, all calculations of the rate of
interest contracted for, charged or received under any Schedule or this
Agreement which are made for the purpose of determining whether such rate
exceeds the maximum lawful contract rate, shall be made, to the extent


<PAGE>   6

permitted by applicable law, by amortizing, prorating, allocating and spreading
in equal parts during the period of the full stated term of the indebtedness
evidenced hereby, all interest at any time contracted for, charged or received
from Lessee or otherwise by Lessor in connection with such indebtedness;
provided, however, that if any applicable state law is amended or the law of the
United States of America preempts any applicable state law, so that it becomes
lawful for Lessor to receive a greater interest per annum rate than is presently
allowed, the Lessee agrees that, on the effective date of such amendment or
preemption, as the case may be, the lawful maximum hereunder shall be increased
to the maximum interest per annum rate allowed by the amended state law or the
law of the United States of America.

17.    EARLY TERMINATION:

       (a) On or after the First Termination Date (specified in the applicable
Schedule), Lessee may, so long as no default exists hereunder, terminate this
Agreement as to all (but not less than all) of the Equipment on such Schedule as
of a rent payment date ("TERMINATION DATE"). Lessee must give Lessor at least
ninety (90) days prior written notice of the termination.

       (b) Lessee shall, and Lessor may, solicit cash bids for the Equipment on
an AS IS, WHERE IS BASIS without recourse to or warranty from Lessor, express or
implied ("AS IS BASIS"). Prior to the Termination Date, Lessee shall (i) certify
to Lessor any bids received by Lessee and (ii) pay to Lessor (A) the Termination
Value (calculated as of the Termination Date) for the Equipment, and (B) all
rent and other sums due and unpaid as of the Termination Date.

       (c) If all amounts due hereunder have been paid on the Termination Date,
Lessor shall (i) sell the Equipment on an AS IS BASIS for cash to the highest
bidder and (ii) refund the proceeds of such sale (net of any related expenses)
to Lessee up to the amount of the Termination Value. If such sale is not
consummated, no termination shall occur and Lessor shall refund the Termination
Value (less any expenses incurred by Lessor) to Lessee.

       (d) Notwithstanding the foregoing, Lessor may elect by written notice, at
any time prior to the Termination Date, not to sell the Equipment. In that
event, on the Termination Date Lessee shall (i) return the Equipment (in
accordance with Section 9) and (ii) pay to Lessor all amounts required under
Section 17(b) less the amount of the highest bid certified by Lessee to Lessor.

real or personal property.

       (c) Time is of the essence of this Agreement. Lessor's failure at any

incurred or assumed by Lessor in effecting such compliance shall constitute
additional rent due to Lessor. Lessee shall pay the additional rent within five

       (e) Any rent or other amount not paid to Lessor when due shall bear
interest, from the due date until paid, at the lesser of eighteen percent (18%)
per annum or the maximum rate allowed by law. Any provisions in this Agreement
and any Schedule that are in conflict with any statute, law or applicable rule
shall be deemed omitted, modified or altered to conform thereto.

       (f) THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER SHALL IN ALL RESPECTS BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH,

of this Agreement, any Schedule, supplement or amendment hereto, of the lease of
any Equipment hereunder, shall not release Lessee from any then outstanding
obligations to Lessor hereunder.

applicable jurisdiction, no security interest therein may be created through the
transfer or possession of this Agreement in and of itself without the transfer
