4. FINANCING TERM. The Base Term of this Schedule shall be 60 months and the

(e)  Security Deposit: $0.00 On the Acceptance Date, Lessee shall pay Lessor
said Security Deposit which shall be held in accordance with paragraph 6 below.

6.   SECURITY INTEREST. This Schedule is intended to be a secured debt
financing transaction, NOT a true lease. See Paragraph 7 below regarding
Lessee's ownership of the Equipment. As collateral security for payment and
performance of all Secured Obligations (defined in Paragraph 8 below) and to
induce Lessor to extend credit from time to time to Lessee (under the Lease or
otherwise), Lessee hereby grants to Lessor a first priority security interest
in all of Lessee's right, title and interest in the Equipment, whether now
existing or hereafter acquired, any sums specified in this Schedule as a
"Security Deposit", and in all Proceeds (defined in Paragraph 8 below). At its
option, Lessor may apply all or any part of any Security Deposit to cure any
default of Lessee under the Lease. If upon final termination of this Schedule,
Lessee has fulfilled all of the terms and conditions hereof, then Lessor shall
pay to Lessee upon Lessee's written request any remaining balance of the
Security Deposit for this Schedule, without interest.

7.   TITLE TO EQUIPMENT; FIRST PRIORITY LIEN. Lessee represents, warrants and
agrees: that Lessee currently is the lawful owner of the Equipment; that good
and marketable title to the Equipment shall remain with Lessee at all times;
that Lessee has granted to Lessor a first priority security interest in the
Equipment and all Proceeds; and that the Equipment and all Proceeds are, and at
all times shall be, free and clear of any Liens other than Lessor's security
interest therein. Lessee at its sole expense will protect and defend Lessor's
first priority security interest in the Equipment against all claims and
demands whatsoever.

8.   CERTAIN DEFINITIONS. "Secured Obligations" means (a) all payments and
other obligations of Lessee under or in connection with this Schedule, and (b)
all payments and other obligations of Lessee (whether now existing or hereafter
incurred) under or in connection with the Master Lease and all present and
future Lease Schedules thereto, and (c) all other leases, indebtedness,
liabilities and/or obligations of any kind (whether now existing or hereafter
incurred, absolute or contingent, direct or indirect) of Lessee to Lessor or to
any affiliate of either Lessor or BANK ONE CORPORATION. "Proceeds" means all
cash and non-cash proceeds of the Equipment including, without limitation,
proceeds of insurance, indemnities and/or warranties.

9.   AMENDMENTS TO MASTER LEASE. FOR PURPOSES OF THIS SCHEDULE ONLY, Lessee and
Lessor agree to amend the Master Lease as follows: (a) public liability or
property insurance as described in the second sentence of Section 8 will not be
required; (b) the definition of "Stipulated Loss Value" in clause (b) of

1. For valuable consideration, the receipt of which is hereby acknowledged, the
undersigned jointly and severally unconditionally guarantee to BANC ONE LEASING
CORPORATION (hereinafter called "Lessor") the full and prompt performance by the
lessee identified above (hereinafter called "Lessee") of all obligations which
Lessee now has or may hereafter have to Lessor under the GUARANTEED LEASE (as
defined below) and unconditionally guarantee the prompt payment when due
(whether at scheduled maturity, upon acceleration or otherwise) of any and all
sums, indebtedness and liabilities of whatsoever nature, due or to become due,
direct or indirect, absolute or contingent, now or hereafter at any time owed or
contracted by Lessee to Lessor under the GUARANTEED LEASE, and all costs and
expenses of and incidental to collection of any of the foregoing, including

"Obligations"). "GUARANTEED LEASE" shall mean the Lease Schedule identified
above (whether now existing or hereafter arising) together with the Master Lease
Agreement identified above ("Master Lease") to the extent that it relates to the
above-described Lease Schedule.

2. This is an absolute and unconditional guarantee of payment and not of

undersigned, to resort to, enforce or exhaust any of its remedies against the
Lessee or any other party who may be liable for payment on any Obligation or to
resort to, marshall, enforce or exhaust any of its remedies against any leased
property or any property given or held as security for this Guaranty or any
Obligation.

3. The undersigned hereby waive and grant to Lessor, without notice to the
undersigned and without in any way affecting the liability of the undersigned,
the right at any time and from time to time, to extend other and additional
credit, leases, loans or financial accommodations to Lessee apart from the
Obligations, to deal in any manner as it shall see fit with any Obligation of
Lessee to Lessor and with any leased property or security for such Obligation,
including, but not limited to, (i) accepting partial payments on account of any
Obligation, (ii) granting extensions or renewals of all or any part of any
Obligation, (iii) releasing, surrendering, exchanging, dealing with, abstaining
from taking, taking, abstaining from perfecting, perfecting, or accepting
substitutes for any or all leased property or security which it holds or may
hold for any Obligation, (iv) modifying, waiving, supplementing or otherwise
changing any of the terms, conditions or provisions contained in any Obligation
and (v) the addition or release of any other party or person liable hereon,
liable on the Obligations or liable on any other guaranty executed to guarantee
any of Lessee's Obligations. The undersigned jointly and severally hereby agree
that any and all settlements, compromises, compositions, accounts stated and
agreed balances made in good faith between Lessor and Lessee shall be binding
upon the undersigned.

4. Every right, power and discretion herein granted to Lessor shall be for the
benefit of the successors or assigns of Lessor and of any transferee or assignee
of any Obligation covered by this Guaranty, and in the event any such Obligation
shall be transferred or assigned, every reference herein to Lessor shall be
construed to mean, as to such Obligation, the transferee or assignee thereof.
This Guaranty shall be binding upon each of the undersigned's executors,
administrators, heirs, successors and assigns.

5. This Guaranty shall continue in force for so long as Lessee shall be
obligated to Lessor pursuant to the Obligations described above. The undersigned
expressly waive notice of the incurring by Lessee of any Obligation to Lessor.
The undersigned also waive presentment, demand of payment, protest, notice of
dishonor or nonpayment of or nonperformance of any Obligation.

6. The undersigned hereby waive any claims or rights which they might now have
or hereafter acquire against Lessee or any other person primarily or
contingently liable on any Obligation of Lessee, which claims or rights arise
from the existence or performance of the undersigned's obligations under this
Guaranty or any other guaranty or under any instrument or agreement with respect
to any leased property or any property constituting collateral or security for
this Guaranty or any other guaranty, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution, indemnification, or any
right to participate in any claim or remedy of Lessor or any other creditor
which the undersigned now has or hereafter acquires, whether such claim or right
arises in equity, under contract or statute, at common law, or otherwise.

7. Lessor's rights hereunder shall be reinstated and revived, and this Guaranty
shall be fully enforceable, with respect to any amount at any time paid on
account of the Obligations which thereafter shall be required to be restored or
returned by Lessor upon the bankruptcy, insolvency or reorganization of the
Lessee, the undersigned, or any other person, or as a result of any other fact
or circumstance, all as though such amount had not been paid.

8. The undersigned jointly and severally agree to pay to Lessor all costs and
expenses, including reasonable attorneys' fees, incurred by Lessor in the
enforcement or attempted enforcement of this Guaranty, whether or not suit is
filed in connection therewith, or in the exercise by Lessor of any right,
privilege, power of remedy conferred by this Guaranty.


                                     Page 1
<PAGE>   8
9. The undersigned represent and warrant that they have relied exclusively on
their own independent investigation of Lessee, the leased property and the
collateral for their decision to guarantee Lessee's Obligations now existing or
thereafter arising. The undersigned agree that they have sufficient knowledge of
the Lessee, the leased property, and the collateral to make an informed decision
about this Guaranty, and that Lessor has no duty or obligation to disclose any
information in its possession or control about Lessee, the leased property, and
the collateral to the undersigned. The undersigned warrant to Lessor that they
have adequate means to obtain from the Lessee on a continuing basis information
concerning the financial condition of the Lessee and that they are not relying
on Lessor to provide such information either now or in the future.

10. As long as any indebtedness under any of the Obligations remains unpaid or
any credit is available to Lessee under any of the Obligations, the undersigned
agree to furnish to Lessor: (a) annual financial statements setting forth the
financial condition and results of operation of the undersigned (financial
statements shall include balance sheet, income statement, changes in financial
position and all notes thereto) within 120 days of the end of each fiscal year
of the undersigned; (b) quarterly financial statements setting forth the
financial condition and results of operation of the undersigned within 60 days
of the end of each of the first three fiscal quarters of the undersigned; and
(c) such other financial information as Lessor may from time to time request
including, without limitation, financial reports filed by the undersigned with
federal or state regulatory agencies.

11. No postponement or delay on the part of Lessor in the enforcement of any
right hereunder shall constitute a waiver of such right. The failure of any
person or entity to sign this Guaranty shall not discharge the liability of any
of the undersigned.

12. This Guaranty remains fully enforceable irrespective of any claim, defense
or counterclaim which the Lessee may or could assert on any of the Obligations
including but not limited to failure of consideration, breach of warranty,
payment, statute of frauds, statute of limitations, fraud, bankruptcy, accord
and satisfaction, and usury, same of which the undersigned hereby waive along
with any standing by the undersigned to assert any said claim, defense or
counterclaim.

13. This Guaranty contains the entire agreement of the parties and supersedes
all prior agreements and understandings, oral or written, with respect to the
subject matter hereof. This Guaranty is not intended to replace or supersede any
other guaranty which the undersigned have entered into or may enter into in the
future. The undersigned may enter into additional guaranties in the future which
may or may not refer to the Master Lease identified above and such guaranties
are not intended to replace or supersede this Guaranty unless specifically
provided in that additional guaranty. The interpretation, construction and
validity of this guaranty shall be governed by the laws of the State of Ohio.
With respect to any action brought by Lessor against Guarantor to enforce any
term of this guaranty, Guarantor hereby irrevocably consents to the jurisdiction
and venue of any state or federal court in Franklin County, Ohio, where Lessor
has its principal place of business and where payments are to be made by Lessee
and Guarantor.

ALL PARTIES TO THIS GUARANTY, INCLUDING GUARANTOR AND LESSOR, WAIVE ALL RIGHTS
TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY ANY PARTY
AGAINST ANY OTHER PARTY ON ANY MATTER WHATSOEVER ARISING OUT OF, IN CONNECTION
WITH OR IN ANY WAY RELATED TO THIS GUARANTY.
