TERMS AND CONDITIONS OF LEASE AGREEMENT

1. TERM AND RENT. Lessor agrees to lease the above described equipment (the
"Equipment") to the Lessee for the term and rental as set forth, payment of the
rental installments to begin on the date of delivery to Lessee.  As long as no
event of default exists, Lessor will not interfere with Lessee's possession, use
and quiet enjoyment of the Equipment.

2. PURCHASE AND ACCEPTANCE. Lessee requests Lessor to purchase the Equipment 
from the Seller and arrange for delivery to Lessee, at Lessee's expense.  
Delivery shall be deemed complete upon the Commencement Date.  LESSOR SHALL 
NOT BE LIABLE FOR LOSS OR DAMAGE OR FOR THE DELAY OR FAILURE OF SELLER TO 
FILL OR DELIVER THE ORDER FOR THE EQUIPMENT.  THE LESSEE REPRESENTS THAT 
LESSEE HAS SELECTED THE EQUIPMENT DESCRIBED ABOVE BEFORE HAVING REQUESTED 
LESSOR TO PURCHASE SAME FOR LEASING TO LESSEE.

3. NON-CANCELLABLE LEASE. THIS IS A NON-CANCELLABLE LEASE.  When Lessee signs 
and delivers a certificate of acceptance for the Equipment, its obligations 
to pay all rent and other amounts when due for the Equipment and otherwise to 
perform as required under the lease are unconditional, irrevocable and 
independent. These obligations are not subject to cancellation, termination, 
modification, repudiation, excuse or substitution by Lessee.  Lessee is not 
entitled to any abatement, reduction, offset, defense or counterclaim with 
respect to these obligations for any reason whatsoever, whether arising out 
of default or other claims against Lessor or the manufacturer or supplier of 
the Equipment, defects in or damage to the Equipment, its loss or destruction 
or otherwise.

4.  DISCLAIMER OF WARRANTIES BY LESSOR; RIGHTS OF LESSEE.  LESSOR MAKES NO 
WARRANTY, EXPRESS OR IMPLIED, AS TO ANY MATTER WHATSOEVER, INCLUDING THE 
CONDITION OF THE EQUIPMENT, ITS MERCHANTABILITY OR ITS FITNESS FOR ANY 
PARTICULAR PURPOSE, AND, AS TO LESSOR, LESSEE LEASES THE EQUIPMENT "AS-IS." 
UNDER NO CIRCUMSTANCES SHALL LESSOR BE RESPONSIBLE FOR ANY INCIDENTAL, OR 
CONSEQUENTIAL DAMAGES IN CONNECTION WITH THIS LEASE AND/OR THE EQUIPMENT 
THEREUNDER, LESSEE IS ENTITLED TO THE PROMISES AND WARRANTIES, INCLUDING 
THOSE OF ANY THIRD PARTY, PROVIDED TO LESSOR BY THE SELLER IN CONNECTION WITH 
OR AS PART OF THE CONTRACT BY WHICH LESSOR ACQUIRED THE EQUIPMENT OR THE 
RIGHT TO POSSESSION AND USE OF THE EQUIPMENT, LESSEE MAY COMMUNICATE WITH THE 
SELLER AND RECEIVE AN ACCURATE AND COMPLETE STATEMENT OF THOSE RIGHTS, 
PROMISES AND WARRANTIES, INCLUDING ANY DISCLAIMERS AND LIMITATIONS OF THEM OR 
OF REMEDIES.

5.  CLAIMS AGAINST SELLER; SELLER NOT AN AGENT OF LESSOR.  If the Equipment is
not properly installed, does not operate as represented or warranted by the
Seller or is unsatisfactory for any reason, Lessee shall make any claim on
account thereof solely against the Seller and shall nevertheless pay Lessor all
rent payable under this Lease.  Lessor agrees to assign to Lessee, solely for
the purpose of making and prosecuting any such claim, any rights it may have
against the Seller for breach of warranty or representation respecting the
Equipment.  Notwithstanding any fees that must be paid to Seller or any agent of
Seller, Lessee understands and agrees that neither the Seller nor any agent or
employee of the Seller is an agent or employee of the Lessor and that neither
the Seller nor its agent or employee is authorized to waive or alter any term or
condition of this Lease.

6.  PAYMENTS. Lessee agrees to pay all Lease payments on the date designated 
by Lessor and to pay such other payments and charges as provided herein.  
These payments shall be increased by any cost or expense Lessor incurs to 
preserve the Equipment or to pay taxes, assessments, fees, penalties, liens 
or encumbrances. IF THE ACTUAL TOTAL COST OF THE EQUIPMENT VARIES FROM THE 
ESTIMATE UPON WHICH THIS LEASE IS BASED, LESSEE AUTHORIZES LESSOR TO ADJUST 
THE LEASE PAYMENTS PROPORTIONATELY, UPWARD OR DOWNWARD, NOT TO EXCEED TEN 
PERCENT (10%), TO COMPENSATE FOR SUCH VARIATION.  Each payment received will 
be applied first, at the Lessor's discretion, to the oldest charge due under 
the Lease. Without Lessor's prior written consent, the acceptance by Lessor 
of a smaller sum than due at any time under this Lease shall not constitute a 
release or an accord and satisfaction of any greater sum due or to become due 
regardless of any endorsement restriction.

7.  TITLE; LOCATION OF THE EQUIPMENT; TERMINATION. Title to the Equipment is in
the Lessor and under no circumstances shall pass to Lessee.  The Equipment shall
be kept at Lessee's address indicated on this Lease and shall not be removed
without the written consent of Lessor.  At the termination of this Lease or upon
Lessee's default, Lessee, its own expense, shall assemble and deliver the
Equipment to Lessor at such place Lessor may designate in writing, in good order
and repair, ordinary wear and tear excepted.  Lessee shall give Lessor 90 days
written notice prior to termination that it is returning the Equipment.

8.  NO ASSIGNMENT BY LESSEE; ASSIGNMENT BY LESSOR.  NEITHER THIS LEASE NOR 
THE RIGHTS HEREUNDER SHALL BE ASSIGNED BY THE LESSEE, NOR SHALL ANY OF THE 
EQUIPMENT BE SUBLEASED BY THE LESSEE WITHOUT THE WRITTEN CONSENT OF THE 
LESSOR.  Lessor may at any time sell or assign to any bank, or other 
financial institution, or any person, firm, or corporation all or part of its 
right, title and interest in and to this Lease and in and to each item of 
Equipment and monies to become due to the Lessor hereunder, and Lessor may 
grant security interest in the Equipment, subject to the Lessee's rights 
therein as set forth in this Lease, and in such events, all the provision of 
this Lease for the benefit of Lessor shall inure to the benefit of and be 
exercised by or on behalf of such assignee, but the assignee, shall not be 
liable for or be required to perform any of Lessor's obligations to Lessee.  
All rental payments due and to become due under this Lease and assigned by 
Lessor shall be paid directly to assignee, upon written notice of such 
assignment to Lessee and the right of the assignee to the payment of assigned 
rentals and performance of all Lessee's obligations and to exercise any other 
of Lessor's rights hereunder shall not be subject to any defense, 
counterclaim or setoff which the Lessee may have or assert against the Lessor 
and the Lessee hereby agrees that it will not assert any such defenses, 
setoffs, counterclaims and claims against the assignee.

9. INSURANCE; HOLD HARMLESS BY LESSEE.  Lessee shall keep the Equipment 
insured against loss by fire, theft and all other hazards (comprehensive 
coverage) at replacement cost by insurers and in form, amount and coverage 
satisfactory to Lessor.  Lessee appoints Lessor as Lessee's attorney in fact 
to endorse any loss payment or returned premium check and to make any claim 
under such insurance. Said policies shall be endorsed with Lessor as a loss 
payee and additional insured and shall contain provisions (a) that such 
insurance shall not be cancelled except upon ten days notice to Lessor and 
(b) that the interest of Lessor shall not be invalidated by any act of 
Lessee.  The policies of insurance or endorsement certificates shall be 
delivered to Lessor within 30 days of the Commencement Date.  In the event of 
loss, destruction or theft of, or damage to, any of the Equipment, Lessee 
will immediately notify Lessor.

The loss, destruction, theft of or damage to the Equipment shall not relieve 
the Lessee from its obligation to pay the full rentals payable hereunder and 
Lessor's remaining residual interest.  Any sums collected from insurance for 
the total loss of any of the Equipment shall be credited to the final 
installments of rent payable hereunder and Lessor's remaining residual 
interest.  If any of the Equipment is partially damaged, Lessee shall repair 
such damage at its own cost and expense and any sums collected on insurance 
on account of such damage shall be applied to the cost thereof, but on 
default of the Lessee in repairing such damage within 30 days of the 
occurrence thereof, the sums collected therefor shall be applied to the last 
maturing installments of rent payable hereunder or to the repair of the 
Equipment at Lessor's sole option.

Lessee shall insure the Lessor and Lessee with respect to liability for 
personal injuries, damage to or loss of use of property resulting from the 
ownership, use and operation of the Equipment with insurers satisfactory to 
Lessor in amounts of at least $500,000 per individual and $1,000,000 per 
occurrence for personal injuries and $100,000 for property damage and deliver 
the policies or certificates thereof to Lessor.

If Lessee shall default in obtaining any insurance described above, Lessor may
place such insurance. Any premiums paid by Lessor shall be additional rent
payable on demand with interest at the highest legal rate from the date of 
payment.



Lessor's sole option, such amounts together with interest may be added to the
lease balance to be paid by Lessee as additional monthly rental. 
NOTWITHSTANDING THE PROVISIONS OF THIS PARAGRAPH, LESSEE WILL SAVE AND HOLD
LESSOR HARMLESS AGAINST ANY CLAIM OR LIABILITY (INCLUDING ATTORNEYS' FEES AND
COSTS AND EXPENSES FOR THE DEFENSE THEREOF) ARISING OUT OF THE OWNERSHIP, USE
OR OPERATION OF THE EQUIPMENT DURING THE PERIOD OF THIS LEASE AND UNTIL THE
EQUIPMENT IS RETURNED TO AND ACCEPTED BY THE LESSOR.

10. REPAIRS; USE; ALTERATIONS.  Lessee, at its own expense, shall keep the 
Equipment maintained in good repair, condition and working order; shall use 
the Equipment lawfully and shall not alter the Equipment without the Lessor's 
prior written consent.  All items which become attached to or a part of the 
Equipment become the property of Lessor.

11. TAXES. Lessee shall reimburse the Lessor (or pay directly if, but only if 
instructed by Lessor) for all charges and taxes (local, state and federal) 
which may now or hereafter be proposed or levied upon the Lease, rental, 
operation, leasing, sale, ownership, possession or use of the Equipment 
excluding all taxes based upon income or gross receipts of Lessor.

12. DEFAULT.  Any of the following shall constitute an event of default by 
Lessee: a) Lessee is to pay when due, any rent or other amount required by 
this Lease; b) Lessee breaches any covenant of this Lease or fails to 
promptly perform any of its terms or conditions, including but not limited to 
return of the Equipment oat the expiration of the lease term; c) Lessee makes 
an assignment for the benefit of creditors; d) a petition is filed by or 
against Lessee in bankruptcy or for the appointment of a receiver; e) 
dissolution or suspension of Lessee's usual business; f) Lessee makes a bulk 
transfer or sale of furniture, furnishings, fixtures or other equipment or 
inventory; g) any representation, warranty, or signature made by Lessee in 
this Lease or related document is incorrect, fraudulent or breached; or h) 
Lessee or any guarantor gives Lessor reasonable cause to be insecure about 
Lessee's or guarantor's willingness or ability to perform the obligations 
under this Lease.

13. LESSOR'S REMEDIES UPON DEFAULT BY LESSEE. If an event of default occurs, 
Lessee's right to continue in possession of the Equipment shall immediately 
cease, and Lessor shall have the right to execute any one or more of the 
following remedies in order to protect its interests and reasonably expected 
profits and benefits of bargains with the Lessee: a) cancel this Lease; 
b)take possession of the Equipment without liability to Lessee for any 
damages occasioned by such taking; c) recover from Lessee, with or without 
repossessing the equipment, the sum of (1) accrued and unpaid rent and other 
amounts payable as of the date of default, (2) the present value (as of the 
date of payment) of the rent for the remaining term of this Lease agreement 
at 5% per annum; and (3) the residual value of the equipment as measured by 
its anticipated fair market value as of the expiration of the lease term; 
provided, however that upon repossession or surrender of the Equipment, 
Lessor shall either sell, lease or otherwise dispose of the Equipment in a 
commercially reasonable manner, with or without notice and on public or 
private bid, and apply the net proceeds (after deducting all expenses, 
including attorneys' fees incurred in connection therewith), the sum of (2) 
and (3) above, or Lessor may retain any repossessed Equipment and credit its 
fair market value to the sums of (2) and (3) above; or d) exercise any other 
right or remedy available to Lessor at law or in equity.

In the event Lessor assigns its right to receive rentals under this agreement 
(but not its individual interest) and in the further event of default by 
Lessee, Lessee remains liable to Lessor for Lessor's remaining residual 
interest in the Equipment as measured above.  This liability of Lessee is 
unconditional and is not affected by Lessor's assignee repossessing and/or 
selling the Equipment to wholly or partially satisfy assignee's right to 
receive the assigned rentals.

14. RENEWAL.  If the Equipment is not delivered to Lessor at the termination 
hereof in accordance with paragraph 7, then this Lease shall renew from month 
to month upon the same terms and conditions, subject to the right of Lessor 
or Lessee to terminate the renewed Lease on 30 days written notice, in which 
event, the Equipment shall immediately be returned to Lessor.  No other 
renewal shall exist except and unless a separate written agreement is entered 
into between Lessor and Lessee.

15. LATE CHARGES.  Without limiting Lessor's remedies above, if Lessee shall 
fail to pay any amount of rental or other payment for a period of ten days 
after its due date, Lessee agrees to pay Lessor a late charge of 5% of each 
such payment or installment.

16. FINANCING STATEMENTS.  The Lessor is authorized to file a financing 
statement signed by the Lessor in accordance with the Uniform Commercial Code 
or one signed by Lessor, as Lessee's attorney in fact.

17. FINANCIAL REPORTS.  Upon request by Lessor, Lessee will promptly furnish 
to Lessor for the most recent quarterly period, a balance sheet and a 
statement of profit, loss and surplus from the beginning of that fiscal year 
to the end of that period certified as correct by an authorized agent of the 
Lessee and such other financial information, books and records the Lessor  
may deem necessary.

18. JURISDICTION; VENUE.  THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE 
STATE OF ILLINOIS.  LESSEE CONSENTS TO THE JURISDICTION OF THE COURTS OF 
ILLINOIS. NO PROVISION WHICH MAY BE CONSTRUED AS UNENFORCEABLE SHALL IN ANY 
WAY INVALIDATE ANY OTHER PROVISION, ALL OF WHICH SHALL REMAIN IN FULL FORCE 
AND EFFECT.

19.  WARRANTIES BY LESSEE.  Lessee warrants and represent that: (a) the
Equipment is being leased for business purposes; (b) all signatures are genuine;
(c) the person signing the Lease is authorized to do so: (d) if more than one
Lessee is named, the liability of each is agreed to be joint and several.

20. INDEMNITY BY LESSEE.  Lessee agrees to indemnify and hold Lessor or any 
assignee harmless from any and all claims, actions, proceedings, expenses, 
damages, and liabilities, including attorneys' fees, arising out of or in any 
manner pertaining to the Equipment or this Lease including, without 
limitation, the ownership, selection, possession, purchase, delivery, 
installation, leasing, operation, use, control, maintenance and return of the 
Equipment and the recovery of claims under insurance policies.

In addition, notwithstanding any other provision of this Lease, if as to any 
Equipment the modified accelerated cost recovery system or depreciation 
deductions allowed under the Internal Revenue Code of 1986, as amended, ("The 
Code") shall be lost, disallowed, eliminated, reduced, recaptured or 
otherwise unavailable to Lessor for any reason, then Lessee shall pay to 
Lessor as additional rent within 30 days after such a loss an amount which 
shall be equal to the sum of (i) the additional federal, state, local and 
foreign income or any other taxes payable as a result of such loss, 
disallowance, elimination, reduction, recapture or unavailability of 
accelerated cost recovery or depreciation deductions plus (ii) the amount of 
any interest, penalties or additions to tax payable by the Lessor as a result 
of such additional tax.

Lessee acknowledges that the Equipment to be leased by Lessor to Lessee 
pursuant to this agreement is owned by Lessor ("Owner"). It is the intent of 
Owner/Lessor and Lessee that this Lease constitute a true lease for Federal 
income tax purposes so that, for the purpose of determining its liability for 
Federal income taxes, Owner shall be entitled to the tax benefits as are 
provided by the Code to an owner of personal property.

The indemnities given and liabilities assumed by the Lessee pursuant to this 
Section 20 shall continue in full force and effect notwithstanding the 
expiration or other termination of this Lease.

21.  NOTICES.  Any notice to a party hereunder shall be sufficiently given if 
mailed to said party by certified mail, return receipt requested, at its 
address set forth herein or such other address as either may designate for 
itself in such written notice to the other.

22.  LABELS AFFIXED TO EQUIPMENT.  Lessor shall have the right, but not the
obligation, to affix or attach ownership identification labels to the Equipment.
Lessee agrees to not remove any such labels.

23.  LESSOR'S EXPENSE.  Lessee shall pay Lessor all costs and expenses,
including reasonable attorneys' fees and the fees of any collection agencies,
incurred by Lessor in enforcing any of the terms, conditions, or provisions
hereof or in protecting Lessor's rights herein.  These costs and expenses shall
include, without limitation, any costs or expenses incurred by the Lessor in any
bankruptcy, reorganization, insolvency or other similar proceeding.

24. ENTIRE AGREEMENT. This Lease constitutes the entire agreement of the parties
in connection with the Equipment.  Neither party relies on any other statements,
understandings, representations or assurances, the same, if any, having been
merged into this agreement.  This agreement cannot be modified except by a
writing signed by each party.  This agreement inures to the benefit of the
heirs, executors, administrators, successors and assigns of the parties.

25. WAIVER OF JURY TRIAL.  Lessor and Lessee, after consulting or having had 
the opportunity to consult with counsel, knowingly, voluntarily and 
intentionally waive any right either of them may have to a trial by jury in 
any litigation based upon or arising out of this Lease or any related 
instrument or agreement or any of the transactions contemplated by this Lease 
or any related instrument or agreement, or any course of conduct, dealing, 
statements (whether oral or written), or actions of either of them.  Neither 
Lessor nor Lessee shall seek to consolidate, by counterclaim or otherwise, 
any such action in which a jury trial has been waived with any other action 
in which a jury trial cannot be or has not been waived.  These provisions 
shall not be deemed to have been modified in any respect or relinquished by 
either Lessor or Lessee except by a written instrument executed by both of 
them.

THIS LEASE AGREEMENT SHALL NOT BE BINDING ON LESSOR UNTIL IT HAS BEEN ACCEPTED
AND EXECUTED BY AN OFFICER OF LESSOR AT ITS OFFICE.  THE UNDERSIGNED AGREE TO
ALL OF THE TERMS AND CONDITIONS ABOVE WHICH ARE PART OF THIS LEASE AGREEMENT.

The undersigned (also referred to as "Lessee") acknowledges receipt in good 
condition of all the above listed property (the "Equipment") and accepts 
Equipment in accordance with all the terms and conditions of the lease 
agreement dated ________________ between Lessor and the undersigned (the

performed all covenants and conditions to be performed under the Lease.

Lessee acknowledges Lessor's right to sell or assign its interests under the

described in the Lease, agrees as follows: (a) that its obligation to pay 
directly the assignee the amounts (whether designated as rentals or 
otherwise) which become due from the Lessee as set forth in the Lease so 
assigned shall be absolutely unconditional and shall be payable whether or 
not the Lease is terminated by operation of law, any act of the parties, or 
otherwise, and it promises to pay such sums notwithstanding any defense, 
set-off or counterclaim whatsoever, whether by reason of breach of the Lease 
or otherwise, which it may or might now or hereafter have against the Lessor 
(the Lessee reserving its right to have recourse directly against the Lessor 
on account of any such defense, set-off or counterclaim), and (b) that, 
subject to and without impairment of the Lessee's leasehold rights in and to 
the Equipment described in the Lease, Lessee holds the Equipment for the 
assignee to the extent of the assignee's rights in the Equipment.
