may be applied by LESSOR to cure any default of LESSEE. LESSEE will from time to
time promptly provide any additional credit or financial information that the
LESSOR deems necessary to this transaction.
7. DISCLAIMER OF WARRANTY. LESSOR not being the manufacturer or the supplier of
the EQUIPMENT, nor a dealer in similar equipment, has not made and does not make
any representation warranty or covenant, express or implied, with respect to the
design, condition, durability, suitability, fitness for use or merchantability
of the EQUIPMENT in any respect. As between LESSOR and LESSEE, the EQUIPMENT
shall be accepted and leased by LESSEE "AS IS" and "WITH ALL FAULTS". LESSEE
agrees to settle all such claims directly with the supplier and will not assert
any such claims or defenses against LESSOR or LESSOR'S assignee. LESSOR assigns
to, authorizes and appoints LESSEE to enforce, in its own name and at its own
expense, any claim, warranty, agreement or representation which may be made
against the supplier, but LESSOR assumes no obligation as to the extent or
enforceability thereof. LESSOR agrees to cooperate with LESSEE in the
enforcement of any manufacturer warranty to the extent LESSOR"S cooperation is
necessary under the terms of any such warranty. No defect or unfitness of the
EQUIPMENT, loss or damage thereto or any other circumstances shall relieve
LESSEE of its obligations under this LEASE which are absolute and unconditional.
In no event shall LESSOR or LESSEE be liable for any consequential damages.
Supplier is not an agent of LESSOR and no employee of supplier is authorized to
waive, supplement or otherwise alter, any provision of this LEASE.
8. ERRORS IN ESTIMATED COST. The amount of each rent payment and the advance
rental initially set forth above are based upon the estimated total cost of the
EQUIPMENT (excluding taxes, transportation and any other charges) which is an
estimate, and each shall be adjusted proportionally if the actual cost of the
EQUIPMENT differs from said estimate. LESSEE hereby authorizes LESSOR to correct
the figures set forth above when the actual cost is known. If the actual cost of
the EQUIPMENT differs from the estimated cost by more than ten percent
(10%)thereof, however, either party at its option may terminate this LEASE by
giving written notice to the other party within fifteen (15) days after
receiving notice of the actual cost or the corrected rent.
9. USE AND RETURN OF EQUIPMENT. The LESSEE shall exercise due and proper care in
the use, repair and servicing of the EQUIPMENT and at all times and at its
expense shall keep and maintain the leased property in good working condition,
order, and repair. LESSEE may alter and upgrade the EQUIPMENT provided that such
alteration or upgrade does not reduce the value or impair the capability of the
EQUIPMENT. LESSEE shall have the right to remove any such alteration or upgrade
before returning the EQUIPMENT to LESSOR so long as the removal does not damage
the EQUIPMENT. LESSEE shall bear all costs associated with the acquisition,
installation and removal of any such alteration or upgrade. Upon the expiration
or termination of this LEASE, LESSEE at its sole expense shall forthwith
properly pack and return the EQUIPMENT to LESSOR, or to such place designated by
LESSOR within 30 miles of EQUIPMENT location, in the same condition as when
received by LESSEE, reasonable wear and tear alone excepted. All replacement
parts, incorporated in or affixed to the EQUIPMENT after the commencement of
this LEASE shall become the property of LESSOR.
10. TITLE; LIENS; TAXES. The Equipment is, and shall at all times be and remain
(i) the sole and exclusive property of LESSOR; and the LESSEE shall have no
right, title or interest therein or thereto except as expressly set forth in
this LEASE; (ii) personal property notwithstanding that the EQUIPMENT or any
part thereof may now be or hereafter become, in any manner affixed or attached
to or imbedded in, or permanently resting upon, real property or any building
thereon. LESSEE agrees to affix nameplates or decals to the EQUIPMENT indicating
LESSOR'S ownership thereof if requested and supplied by LESSOR.

                                                                   EXHIBIT 10.27

LESSEE shall keep the EQUIPMENT free and clear of levies, liens and encumbrances
and shall pay all license and registration fees, assessments, filing or
recording fees, documentary stamp tax, sale/use taxes, personal property taxes,
gross receipt taxes, excise taxes including value added taxes and all other
taxes (local, state and federal) which may now or hereafter be imposed upon the
ownership, leasing, rental, sale, purchase, possession or use of the EQUIPMENT
whether assessed to LESSOR or LESSEE excluding, however, all taxes on or
measured by LESSOR'S net income.
      If such taxes are levied against the LESSOR, the LESSOR shall have the
right, subject to the following paragraph, but not the obligation, to pay any
such taxes, whether levied against the LESSOR or the LESSEE. In such event the
LESSEE shall reimburse the LESSOR therefor within five (5) days after receipt of
invoice and for the failure to make such reimbursement when due the LESSOR shall
have all remedies provided herein with respect to the nonpayment of the rental
hereunder. LESSEE shall give LESSOR immediate notice of any attachment or other
judicial process, liens or encumbrances affecting the EQUIPMENT and shall
indemnify and save LESSOR harmless from any loss or damage caused thereby.
      Notwithstanding the foregoing, LESSEE shall have the right, at its expense
and by appropriate legal proceedings, to contest the validity, applicability or
amount of any fees, assessments or taxes imposed upon the EQUIPMENT provided
that LESSEE shall not cause a tax lien to be levied against the EQUIPMENT or
LESSOR. LESSOR agrees to cooperate with LESSEE in any such contest and will
permit LESSEE to contest the same in the name of LESSOR (if required by law) or
in the name of LESSEE, all at LESSEE"S cost and expense. The non-payment of any
fee, tax or assessment by LESSEE in connection with such contest shall not be
deemed a default hereunder until final determination of such contest and
expiration of any due date established therein.
11. FILING. LESSEE hereby authorizes LESSOR to file financing statements with
respect to the EQUIPMENT or any collateral provided by LESSEE to LESSOR prior to
or following LESSOR's acceptance of this LEASE, in any State of the United
States in which the EQUIPMENT is located. LESSEE shall execute such supplemental
instruments and financing statements if LESSOR deems such to be necessary or
advisable and shall otherwise cooperate to defend the title of the LESSOR by
filing or otherwise. LESSEE, upon demand, shall promptly pay to LESSOR all
filing costs and fees incurred or paid by LESSOR.
12. INSURANCE. Commencing on the date risk passes to LESSOR from the supplier
and continuing until LESSEE has redelivered possession of the EQUIPMENT to
LESSOR, LESSEE, at its expense, shall keep the EQUIPMENT insured against all
risks of loss or damage from every cause whatsoever for the greater of the total
rent for the full term of this LEASE or the full undepreciated replacement value
(new) of the EQUIPMENT, and shall carry public liability insurance, both
personal injury and property damage, covering the EQUIPMENT and its use. All
insurance shall be of a type, form, in amounts, with companies and contain terms
and conditions reasonably satisfactory to LESSOR. Certificates of insurance or
other evidence satisfactory to LESSOR, including the original or certified
copies of the actual policies showing the existence of insurance in accordance
herewith, and the terms, conditions and payments therefor shall be delivered to
LESSOR upon Lessor"s request. Said insurance shall provide for loss, if any,
payable to LESSOR and LESSEE as their interests may appear and shall name LESSOR
as an additional insured for purposes of liability insurance. The proceeds of
insurance payable as a result of loss of or damage to EQUIPMENT shall be
applied, at the option of LESSEE: (a) toward the replacement, restoration or
repair of EQUIPMENT which may be lost, stolen, destroyed or damaged; or (b)
toward payment of the obligations of LESSEE hereunder. In the event the LESSEE
elects to apply insurance proceeds to the repair or to the replacement of the
damaged EQUIPMENT, this LEASE shall continue in full force and effect. In the
event LESSEE elects to apply insurance proceeds to the payment of LESSEE"S
obligations for rent hereunder, the LESSEE's obligations for the rent hereunder
shall be reduced by the amount of such insurance proceeds, but the LESSEE shall
be liable for any additional rents due. Such reduction of rents shall be
allocated solely to the item or items lost, stolen, damaged or destroyed.
13. LOSS; DAMAGE. LESSEE assumes and shall bear the risk of loss and damage to
the EQUIPMENT from every cause whatsoever, whether or not insured. In the event
of any loss or damage to the EQUIPMENT, LESSEE, at the option of LESSEE, shall
(a) place the same in good repair, condition and working order; or (b) replace
the same with new EQUIPMENT; or (c) immediately pay to LESSOR the following
amount: the greater of (x) the total unpaid rentals for the entire term hereof
(discounted to present value at the rate of six (6) percent per annum plus any
amount due LESSOR pursuant to Section 18 hereof or (y) the fair market value of
the EQUIPMENT immediately prior to the loss or damage. Upon such payment,
together with payment of all other sums owing on said LEASE to and including
such payment date, LESSOR will transfer title to the affected EQUIPMENT to
LESSEE "as is", "where is", and without warranty, express or implied but
including the warranty of good and marketable title.
14. INDEMNITY. Lessee does hereby assume liability for and does agree to
indemnify, protect, save and keep harmless LESSOR, and any assignee of LESSOR
from and against any and all liabilities, losses, damages, penalties, claims,
actions, suits, costs, expenses and disbursements, including court costs and
reasonable legal expenses, of whatever kind and nature, imposed on, incurred by
or asserted against LESSOR, and any assignee of LESSOR (whether or not also
indemnified against by any other person) in any way relating to or arising out
of this LEASE or the manufacture, purchase, ownership, delivery, lease,
possession, use, operation, condition, return or other disposition of the
EQUIPMENT by LESSEE, including without limitation any claim alleging latent or
other defects, whether or not discoverable by LESSOR or LESSEE; any claim for
patent, trademark or copyright infringement; any claim arising out of strict
liability in tort; and any taxes for which LESSEE is responsible pursuant to
this LEASE, but excluding any such claims arising from acts or omissions of
LESSOR or its assignees.
15. DEFAULT. Any of the following events or conditions shall constitute an event
of default hereunder; (a) LESSEE'S failure to pay when due any rent or other
amount due hereunder within 30 days after receipt by LESSEE of notice of
default: (b) LESSEE'S default in performing any other term, covenant or
condition hereof if such default is not cured within 30 days after receipt by
LESSEE of notice of default; (c) seizure of any EQUIPMENT under legal process;
(d) the filing by or against LESSEE of a petition for reorganization or
liquidation under the Bankruptcy Code or any amendment thereto or under any
other insolvency law providing for the relief of debtors; (e) the voluntary or
involuntary making of an assignment of a substantial portion of its assets by
LESSEE for the benefit of creditors, appointment of a receiver or trustee for
LESSEE or for any of LESSEE'S asset institution by or against LESSEE of any
formal or informal proceeding for dissolution, liquidation, settlement of claims
against or winding up of the affairs of LESSEE, or the making by LESSEE of a
transfer of all or a material portion of LESSEE's assets or inventory not in the
ordinary course of business and not for equivalent consideration.
16. REMEDIES. Upon LESSEE'S default, LESSOR shall have the right to exercise any
one or more of the following remedies; (a) without affecting LESSOR'S title or
right to possession of the EQUIPMENT, declare due, sue for and recover all rents
and other amounts then accrued or thereafter accruing for the entire lease term,
discounted to present value at 8% per annum or the sum calculated per paragraph
27 below, whichever is greater, (b) require LESSEE to promptly redeliver the
EQUIPMENT in the manner specified in Section 9 hereof; or (c) repossess the
EQUIPMENT without notice, legal process, prior judicial hearing or liability for
trespass (which rights LESSEE hereby voluntarily, intelligently and knowingly
waives). Such return or repossession of EQUIPMENT shall not terminate this LEASE
unless LESSOR so notifies LESSEE in writing. LESSOR, at its option may sell or
re-lease the EQUIPMENT upon such terms as it reasonably determines and apply the
proceeds to LESSEE's obligations hereunder, after deducting from such proceeds
all costs and expenses of repossession and disposition, reasonable attorney's
fees, plus any amounts due LESSOR pursuant to Section 18 hereof. LESSEE shall
promptly pay any resulting deficiency, together with interest at the lesser of
sixteen (16%) percent and LESSOR's reasonable attorneys' fees if legal action is
required to collect such deficiency. If LESSOR is unable to repossess the
EQUIPMENT for any reason, the EQUIPMENT shall be deemed a total loss and LESSEE
shall pay to LESSOR the amount due pursuant to Section 13 (c). All such remedies
are cumulative and may be enforced separately or concurrently and are in
addition to any other rights or remedies available to LESSOR at law or in
equity. The foregoing provisions of this Section 16 are subject to any mandatory
requirement of applicable law then in effect.
17. ASSIGNMENT. Without the prior written consent of LESSOR, LESSEE shall not
assign, transfer, pledge or hypothecate this LEASE and EQUIPMENT or any interest
in this LEASE or in and to the EQUIPMENT or permit its rights under this LEASE
to be subject to any lien, charge or encumbrance of any nature. Notwithstanding
the foregoing, LESSEE may assign the LEASE, the EQUIPMENT and its interest in
this LEASE and the EQUIPMENT to an affiliate or in connection with a sale of all
or substantially all of its assets to, or consolidation with or merger of LESSEE
into, any entity so long as such entity assumes the obligations of LESSEE
hereunder and immediately following such event is, in the reasonable opinion of
LESSOR, no less creditworthy than was LESSEE immediately prior to such event.
LESSOR shall have the right to assign this LEASE or any part thereof. If LESSOR
assigns the rents reserved herein or all or any of the LESSOR's other rights
hereunder, or amounts equal thereto, the right of the assignee to receive the
rentals as well as any other right of the assignee shall not be subject to any
defense, setoff, counterclaim or recoupment which may arise out of any breach or
obligation of LESSOR or by reason of any other indebtedness or liability at any
time owing by LESSOR to LESSEE. All rentals due hereunder shall be payable to
assignee by LESSEE in accordance with the terms hereof. On receipt of
notification of such assignment, LESSEE, subject to its rights hereunder, shall
become the pledgeholder of the EQUIPMENT for and on behalf of the assignee and
will relinquish possession thereof only to the assignee or pursuant to its
written order subject to LESSEE"s rights hereunder. LESSEE, on receiving notice
of any such assignment, shall make payments as may therein be directed.
Following such assignments, the term "LESSOR" shall be deemed to include or
refer to LESSOR'S assignee, provided that no such assignee shall be deemed to
assume any obligation or duty imposed upon LESSOR hereunder and LESSEE shall
look only to LESSOR for performance thereof. There shall be only one executed
counterpart of this LEASE marked "Original" and all other counterparts shall be
marked "Duplicate". To the extent that LEASE constitutes chattel paper (as
defined in the Uniform Commercial Code) no security interest in this lease may
be created through the transfer or possession of any counterpart other than the
original.
18. DEPRECIATION AND INVESTMENT TAX CREDIT INDEMNITY. (THIS SECTION DOES NOT
APPLY IF LESSOR HAS AGREED IN WRITING TO PASS THE INVESTMENT TAX CREDIT (ITC) TO
LESSEE.) If, as to any EQUIPMENT, under any circumstances and for any reason
whatsoever, except through the fault of the LESSOR, LESSOR shall lose or shall
not have the right to claim, or there shall be disallowed or recaptured
(collectively a "loss") (1) any portion of the maximum ITC, allowable under the
Internal Revenue Code of 1954, as amended, for new property with a useful life
equivalent to the lease term for such EQUIPMENT; or (2) any prortion of the
claimed depreciation deductions for such EQUIPMENT, based on the cost thereof,
LESSEE agrees to pay LESSOR upon demand an amount which, in the reasonable
opinion of LESSOR, will cause LESSOR's after tax net yield in respect of such
equipment to equal the net yield that LESSOR would have received if LESSOR had
not suffered such loss.
