                              TERMS AND CONDITIONS

1.   LEASE TERM: The lease term for each Unit shall start on its Delivery Date
(the date (a) Lessor executes this Lease, (b) Lessor takes title to the Unit, or
(c) Lessee or its agent takes control of physical possession of the Unit,
whichever is latest), provided the Delivery Date is on or before the utilization
date stated above, and shall continue for the number of months stated above. If
the Delivery Date is not on or before the utilization date, Lessee shall, at the
option of Lessor, assume Lessor's obligations to purchase and pay for the Unit.
Lessee shall execute and send Lessor's delivery supplement to Lessor promptly
after delivery of a Unit.


2.   RENT: Lessee shall pay to Lessor, at PO Box 100647 Pasadena, CA 91189-0647
or such other location Lessor designates in writing, rent for each Unit as
stated above starting (a) on its Delivery Date if the rent is to be paid in
advance, or (b) one month (or other period as stated above) after its Delivery
Date if the rent is to be paid in arrears. An amount equal to the first rent
payment for each Unit must accompany this document when it is submitted to
Lessor. If Lessor executes this document, the amount shall be the first rent
payment. If Lessor does not execute this document, the amount shall be returned
to Lessee. If Lessor does not receive a rent payment on the date it is due,
Lessee shall pay to Lessor, on demand, a late payment charge equal to five
percent (5%) of the rent payment not paid when due or the highest charge allowed
by law, whichever is less.

3.   NO ABATEMENT: Lessee shall not be entitled to abatement or reduction of
rent or setoff against rent for any reason whatsoever. Except as otherwise
provided, this Lease shall not terminate because of, nor shall the obligations
of Lessor or Lessee be affected by damage to, any defect in, destruction of, or
loss of possession or use of a Unit; the attachment of any lien, security
interest or other claim to a Unit; any interference with Lessee's use of a Unit;
Lessee's insolvency or the commencement of any bankruptcy or similar proceeding
by or against Lessee, or any other cause whatsoever.

4.   DISCLAIMER OF WARRANTIES: Lessee acknowledges and agrees that Lessor is not
the manufacturer of the Unit(s) and that Lessee has selected each Unit based on
Lessee's own judgment without any reliance whatsoever on any statements or
representations made by Lessor. AS BETWEEN LESSOR AND LESSEE, THE UNIT(S) ARE
PROVIDED "AS IS" WITHOUT ANY WARRANTIES OF ANY KIND. LESSOR HEREBY EXPRESSLY
DISCLAIMS a) ALL WARRANTIES OF MERCHANTABILITY, b) ALL WARRANTIES OF FITNESS FOR
A PARTICULAR PURPOSE, AND  c) ALL WARRANTIES AGAINST INFRINGEMENT OR THE LIKE.
Lessor assigns to Lessee its interest in any of the manufacturer's warranties on
the Unit(s).

5.   POSSESSION, USE AND MAINTENANCE: Lessee shall not (a) use, operate,
maintain or store a Unit improperly, carelessly, unsafely or in violation of any
applicable law or regulation or for any purpose other than in the conduct of
Lessee's business; (b) abandon a Unit; (c) sublease a Unit, permit the use of a
Unit by anyone other than Lessee, change the use of unit from that specified in
the Application Survey/Usage Rider attached hereto, or change the location of a
Unit from that specified above, without the prior written consent of Lessor; or
(d) create or allow to exist any lien, claim, security interest or encumbrance
on any of its rights hereunder or a Unit. A Unit is and shall remain personal
property regardless of its use or manner of attachment to realty. Lessor and its
agent shall have the right (but not the obligation) to inspect a Unit and
maintenance records relating to it and observe its use. Lessee, at its expense,
shall maintain each Unit in good operating order, repair and condition and shall
perform maintenance at least as frequently as stated in any applicable
operator's guide, service manual, or lubrication and maintenance guide. Lessee
shall not alter any Unit or affix any accessory or equipment to it if doing so
will impair its originally intended function or use or reduce its value. Any
alteration or addition to a Unit shall be the responsibility of and at the sole
risk of Lessee. All parts, accessories and equipment affixed to a Unit shall be
subject to the security interest of Lessor.

     6. TAXES: Lessee shall promptly pay or reimburse Lessor for all fees,
charges and taxes of any nature, including, without limitation, personal
property taxes, together with any penalties, fines or additions to tax and
interest thereon (collectively, "Taxes") levied on or assessed against Lessor in
connection with the ownership, leasing, rental, sale, possession, purchase, or
use of a Unit; excluding however, all charges or taxes on or measured by
Lessor's net income, or charges or taxes levied on or assessed against Lessor in
connection with a Unit after the Unit is returned to Lessor in accordance with
the terms of this Lease. If the reimbursement to Lessor of Taxes constitutes
income for federal, state or local tax purposes and if the Lessor is not
entitled to a deduction for the full amount of the reimbursement, the Lessee
shall pay the Lessor an additional amount such that the net amount received by
Lessor after payment of all related Taxes equals the amount which Lessor would
have received if no such Taxes were payable. Lessee shall prepare and timely
file, in a manner satisfactory to Lessor, any reports or returns which may be
required with respect to a Unit, including, without limitation, personal
property tax returns. For purposes of this section, in computing Lessor's Taxes
attributable to a reimbursement, it shall be assumed that the Lessor is in the
highest marginal tax rate applicable to corporations at the time the
reimbursement is made, and that the term "Lessor" shall include any affiliated
group, within the meaning of Section 1504 of the Internal Revenue Code of 1986,
of which Lessor is a member for any year in which a consolidated or combined
income tax return is filed for the affiliated group.

     7. LOSS OR DAMAGE. Lessee shall bear the risk, of any Casualty Occurrence
(the Unit is worn out, lost, stolen, destroyed, taken by government action or,
in Lessor's opinion, irreparably damaged) or other damage from the time it is
purchased by Lessor until it is returned to Lessor. Lessee shall give Lessor
prompt notice of a Casualty Occurrence or other damage. If, in Lessor's opinion,
the damage is not a Casualty Occurrence. Lessee shall, at its expense, promptly
restore the Unit to the condition required by Section 5. If a Casualty
Occurrence, Lessee shall pay to Lessor on the first rent payment date following
the Casualty Occurrence (thirty (30) days after the Casualty Occurrence if there
is no rent payment date remaining) the lesser of (a) the sum of (i) all amounts
then due under this Lease with respect to the Unit, (ii) the present value of
all unpaid rent for the Unit, and (iii) the present value of the Purchase Price
of the Unit as stated on the front hereof; or (b) the maximum amount permitted
by law. Present values will be determined by discounting at the implicit
interest rate of this Lease. Upon making this payment, the lease term with
respect to the Unit shall terminate and Lessee shall be entitled to possession
of the Unit and to any recovery in respect to it (subject to the rights of any
insurer).

     8. WAIVER AND INDEMNITY: LESSEE HEREBY AGREES TO RELEASE, DEFEND, INDEMNIFY
AND HOLD HARMLESS LESSOR, ITS DIRECTORS, OFFICERS, EMPLOYEES, AGENTS AND ASSIGNS
FROM AND AGAINST ANY CLAIMS OF LESSEE OR THIRD PARTIES, INCLUDING CLAIMS BASED
UPON BREACH OF CONTRACT, BREACH OF WARRANTY, PERSONAL INJURY, PROPERTY DAMAGE,
STRICT LIABILITY OR NEGLIGENCE, FOR ANY LOSS, DAMAGE OR INJURY CAUSED BY OR
RELATING TO THE DESIGN, MANUFACTURE, SELECTION, DELIVERY, CONDITION, OPERATION,
USE, OWNERSHIP, MAINTENANCE OR REPAIR OF ANY UNIT. FURTHER, LESSEE AGREES TO BE
RESPONSIBLE FOR ALL COSTS AND EXPENSES, INCLUDING REASONABLE ATTORNEYS' FEES,
INCURRED BY LESSOR OR ITS DIRECTORS, OFFICERS, EMPLOYEES, AGENTS AND ASSIGNS IN
DEFENDING SUCH CLAIMS OR IN ENFORCING THIS PROVISION. UNDER NO CONDITION OR
CAUSE OF ACTION SHALL LESSOR BE LIABLE FOR ANY LOSS OF ACTUAL OR ANTICIPATED
BUSINESS OR PROFITS OR ANY SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES.

     9. INSURANCE: Lessee, at its expense, shall keep each Unit insured for the
benefit of Lessor against all risks for not less than the amount described in
Section 7 and shall maintain comprehensive public liability insurance (including
product and broad form contractual liability) covering the Unit for not less
than $1,000,000 combined coverage for bodily injury and property damage. All
insurance shall be in a form and with companies as Lessor shall approve, shall
specify Lessor and Lessee as name insured, shall be primary, without the right
of contribution from any other insurance carried by Lessor, and shall provide
that the insurance may not be canceled or altered so as to affect the interest
of Lessor without at least ten (10) days' prior written notice to Lessor. All
insurance covering loss or damage to a Unit shall name Lessor as loss payee.
Lessee shall not make adjustments with insurers except with Lessor's prior
written consent and hereby irrevocably appoints Lessor as Lessee's
attorney-in-fact to receive payment of and to endorse all checks, drafts and
other documents and to take any other actions necessary to pursue insurance
claims and recover payments if Lessee fails to do so. Lessee shall promptly
notify Lessor of any occurrence which may become the basis of a claim and shall
provide Lessor with all requested pertinent data. Lessee shall promptly deliver
to Lessor evidence of such insurance coverage.

     10. EVENTS OF DEFAULT: Each of the following constitutes an event of
default ("Event of Default"): (a) Lessee fails to make any payment when due; (b)
any representation or warranty to Lessor which is incorrect or misleading; (c)
Lessee fails to observe or perform any covenant, agreement or warranty made by
Lessee and the failure continues for ten (10) days after written notice to
Lessee; (d) any default occurs under any other agreement between Lessee and
Lessor or any affiliate of Lessor; (e) Lessee or any guarantor of this Lease
ceases to do business, becomes insolvent, makes an assignment for the benefit of
creditors or files any petition or action under any bankruptcy, reorganization,
insolvency or moratorium law, or any other law or laws for the relief of, or
relating to, debtors; (f) filing of any involuntary petition under any
bankruptcy statute against Lessee or any guarantor of this Lease, or appointment
of a receiver, trustee, custodian or similar official to take possession of the
properties of Lessee or any guarantor of this Lease, unless the petition or
appointment ceases to be in effect within thirty (30) days after filing or
appointment; and (g) breach or repudiation of a guaranty obtained by Lessor in
connection with this Lease.

     11. REMEDIES: If an Event of Default occurs, Lessor may (a) proceed by
court action to enforce performance by Lessee of the covenants of this Lease or
to recover damages for their breach or (b) by notice in writing to Lessee
terminate this Lease, in which event Lessee shall remain liable as provided
herein and Lessor may do any one or more of the following: (i) declare the
balance due (or the maximum amount permitted by law if recovery of the entire
balance due is prohibited) with respect to each Unit immediately due and payable
and recover any additional damages and expenses sustained by Lessor due to
breach of any covenant, representation or warranty in this Lease other than for
the payment of rent; (ii) enforce the security interest granted herein; (iii)
require Lessee to return each Unit and additional security pursuant to Section
12; and (iv) enter the premises where any Unit or additional security may be and
take possession of it without notice, liability or legal process. Lessee agrees
to pay all charges, costs, expenses and reasonable attorney's fees incurred by
Lessor in enforcing this Lease. Lessor has all rights given to a secured party
by law. Lessor may undertake commercially reasonable efforts to sell or release
a Unit and additional security, and the proceeds of any sale or re-lease shall
be applied in the following order: (i) to reimburse Lessor for all expenses of
retaking, holding, preparing for sale or re-lease and selling or re-leasing the
Unit and additional security, including any taxes, charges, costs, expenses and
reasonable attorney's fees incurred by Lessor: (ii) to pay Lessor all amounts
which under the terms of this Lease are due or have accrued as of the date of
Lessor's receipt of the proceeds: and (iii) to pay Lessor the balance due (or
the maximum amount permitted by law if recovery of the entire balance due is
prohibited) with respect to the Unit and additional security. Any surplus shall
be paid to the person entitled to it. Lessee shall promptly pay any deficiency
to Lessor. Lessee acknowledges that sales of cash or credit to a wholesaler,
retailer or user of a Unit or additional security are all commercially
reasonable. The remedies provided to Lessor shall be cumulative and shall be in
addition to all other remedies existing at law or in equity. If Lessee fails to
perform any of its obligations under this Lease, Lessor may perform the
obligations, and the expenses incurred by Lessor as a result shall be payable by
Lessee upon demand.

     12. RETURN OF UNIT: If Lessor shall rightfully demand possession of a Unit,
Lessee, at its expense, shall promptly deliver possession of the Unit to Lessor,
properly protected and in the condition required by Section 5, at the option of
Lessor, (a) to the premises of the nearest Caterpillar dealer selling equipment
of the same type as the Unit, or (b) on board a carrier named by Lessor and
shipping it, freight collect, to the destination designated by Lessor. If the
Unit is not in the condition required by Section 5, Lessee shall pay to Lessor,
on demand, all costs and expenses incurred by Lessor to bring the Unit into the
required condition.

     13. MANDATORY FINAL PAYMENT: If the Mandatory Final Payment box is checked,
at the end of lease term with respect to a Unit, provided this Lease has not
been terminated with respect to it, Lessee shall pay the Final Payment stated on
the front hereof. Upon receipt of the Final Payment, and all other amounts due
under this Lease, plus an amount equal to any taxes due in connection with the
transfer of the Unit or the delivery of the bill of sale, Lessor shall deliver
to Lessee, upon request, a bill of sale without warranties except that the Unit
is free of all encumbrances of any person claiming through Lessor. Lessee shall
purchase the Unit "AS IS, WHERE IS, WITH ALL FAULTS."

     14. OPTIONAL FINAL PAYMENT: If the Optional Final Payment box is checked
and if no Event of Default shall have occurred and be continuing, Lessee may, by
notice delivered to Lessor not less than sixty (60) days prior to the end of the
lease term with respect to a Unit, elect to pay the Final Payment stated on the
front. Payment of the Final Payment shall be due at the end of the lease term.
Upon payment of the Final Payment and all other amounts due under this Lease,
plus an amount equal to any taxes due in connection with the transfer of the
Unit or the delivery of the bill of sale, Lessor shall deliver to Lessee, upon
request, a bill of sale without warranties except that the Unit is free of all
encumbrances of any person claiming through Lessor. Lessee shall purchase the
Unit "AS IS, WHERE IS, WITH ALL FAULTS". If Lessee does not elect to pay the
Final Payment, Lessee, upon expiration of the lease term, shall return the Unit
to Lessor as provided in Section 12 and furnish Lessor with documentation, as
Lessor may reasonably request, conveying to Lessor all of Lessee's right, title
and interest in the Unit, free and clear of all liens, claims, security
interests and encumbrances other than those of Lessor.

     15. SECURITY INTEREST; LESSEE REPRESENTATIONS: Unless applicable law
provides otherwise, title to a Unit shall remain in Lessor as security for the
obligations of Lessee hereunder until Lessee has fulfilled all of its
obligations. Lessee hereby grants to Lessor a continuing security interest in
the Unit, including all attachments, accessories and optional features therefor
(whether or not installed thereon) and all substitutions, replacements,
additions, and accessions thereto, and proceeds of all of the foregoing,
including, but not limited to, proceeds in the form of chattel paper to secure
the payment of all sums due hereunder. Lessee will, at its expense, do any act
and execute, acknowledge, deliver, file, register and record any documents which
Lessor deems desirable in its discretion to protect Lessor's security interest
in the Unit and Lessor's rights and benefits under this Lease. Lessee hereby
irrevocably appoints Lessor as Lessee's Attorney-in-Fact for the signing and
filing of such documents and authorizes Lessor to delegate these limited powers.
Lessee represents and warrants to Lessor that (a) Lessee has the power to make,
deliver and perform under this Lease, (b) the person executing and delivering
this Lease is authorized to do so on behalf of Lessee, and (c) this Lease
constitutes a valid obligation of Lessee, legally binding upon it and
enforceable in accordance with its terms. Lessee shall, during the lease term,
display in a prominent place on the Unit labels supplied by Lessor stating that
the Unit is leased from Lessor. Lessee further represents and warrants to Lessor
that Lessee is and shall remain a Corporation registered in the state of NV
("Business Location"); and Lessee will not change its form of business
organization or Business Location without prior written notice to Lessor.

     16. ASSIGNMENT; COUNTERPARTS: The rights of Lessor under this Lease and
title to the Unit may be assigned by Lessor at any time. If notified by Lessor,
Lessee shall make all payments due under this Lease to the party designated in
the notice, without offset or deduction. No assignment of this Lease or any
right or obligation under it may be made by Lessee without the prior written
consent of Lessor. This Lease shall be binding upon and benefit Lessor and
Lessee and their respective successors and assigns. If this Lease is assigned by
Lessor to a partnership or trust, the term "Lessor" shall thenceforth mean and
include the partnership or trust and shall also include, for purposes of
Sections 4, 5, 6, 7, 8 and 9, each partner in or beneficiary of the partnership
or trust. Although multiple counterparts of this document may be signed, only
the counterpart accepted, acknowledged and certified by Caterpillar Financial
Services Corporation on the signature page thereof as the original will
constitute original chattel paper.

     17. EFFECT OF WAIVER; ENTIRE AGREEMENT; MODIFICATION OF LEASE; NOTICES: A
delay or omission by Lessor to exercise any right or remedy shall not impair any
right or remedy and shall not be construed as a waiver of any breach or default.
Any waiver or consent by Lessor must be in writing. This Lease completely states
the rights of Lessor and Lessee and supersedes all prior agreements with respect
to the Unit. No variation or modification of this Lease shall be valid unless in
writing. All notices shall be in writing, addressed to the other party at the
address stated on the front or at such other address as may hereafter be
furnished in writing.

     18. APPLICABLE LAW, JURISDICTION AND JURY TRIAL WAIVER PROVISIONS: This
Agreement shall be governed by and construed under the laws of the State of
Tennessee, without giving effect to the conflict-of-laws principles thereof, and
Lessee hereby consents to the jurisdiction of any state or federal court located
within the State of Tennessee. THE PARTIES HERETO HEREBY WAIVE THE RIGHT TO
TRIAL BY JURY IN ANY ACTION ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE
OBLIGATIONS OR THE COLLATERAL.

     19. SEVERABILITY; SURVIVAL OF COVENANTS: If any provision of this Lease
shall be invalid under any law, it shall be deemed omitted but the remaining
provisions hereof shall be given effect. All obligations of Lessee under this
Lease shall survive the expiration or termination of this Lease to the extent
required for their full observance and performance.
