                        ---
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.

Lessor agree to amend the Master Lease as follows: (a) public liability or

Schedule to "Lessee" and "Lessor" shall be changed to "Borrower" and "Lender"
respectively.

10.  STIPULATED LOSS VALUE. For purposes of this Schedule only, the "Stipulated
Loss Value" of any item of Equipment during its Lease Term equals the aggregate
of the following as of the date specified by Lessor: (a) all accrued and unpaid
interest, late charges and other amounts due under this Schedule and the Master
Lease to the extent it relates to this Schedule as of such specified date, plus
(b) the remaining principal balance due and payable by Lessee under this
Schedule as of such specified date, plus (c) interest on the amount described in
the foregoing clauses (a) and

(b)  at the Overdue Rate commencing with the specified date; provided, that the
foregoing calculation shall not exceed the maximum amount which may be collected
by Lessor from Lessee under applicable law in connection with enforcement of
Lessor's rights under this Schedule and the Master Lease to the extent it
relates to this Schedule.

Lessee Name: MEADOW VALLEY CONTRACTORS, INC
             ------------------------------

Equipment Cost: $164,836.22
                -----------

     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, including but
not limited to obligations under equipment leases and promissory notes executed
in connection with anticipated equipment leases (including but not limited to
all present and future lease schedules and promissory notes under the Master
Lease identified above, with a total original equipment cost to the Lessor of no
more than the amount of the Equipment Cost set forth above), 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,
and all costs and expenses of and incidental to collection of any of the
foregoing, including reasonable attorneys' fees (all of the foregoing
hereinafter called "Obligations"). It is the undersigned's express intention
that this guaranty in addition to covering all present Obligations of Lessee to
Lessor, shall extend to all future Obligations of Lessee to Lessor, whether or
not such Obligations are reduced or entirely extinguished and thereafter
increased or are reincurred, whether or not such Obligations are related to the
Master Lease identified above, whether or not such Obligations exceed the
Equipment Cost identified above, and whether or not such Obligations are
specifically contemplated by the undersigned, Lessee, and Lessor as of the date
hereof.

     2.   This is an absolute and unconditional guarantee of payment and not of
collection. Lessor shall not be required, as a condition of the liability of the
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, and thereafter until Lessor shall have actually received
written notice of the termination hereof from the undersigned, it being
contemplated that Lessee may borrow, lease, repay and subsequently borrow money
from or lease property from, or become obligated to, Lessor from time to time,
and the undersigned, not having given notice of the termination hereof as herein
provided for, shall be deemed to have permitted this Guaranty to remain in full
force and effect for the purpose of inducing Lessor to make further leases or
loans to Lessee; provided, however, no notice of termination of this Guaranty
shall affect in any manner the rights of Lessor arising under this Guaranty with
respect to the following: (a) any Obligation incurred by Lessee in connection
with the Master Lease identified above with a total equipment cost of no more
than the amount of the Total Equipment Cost set forth above, whether such
obligation is in the form of a lease or a promissory note; or (b) any Obligation
incurred by Lessee prior to receipt by Lessor of written notice of termination
or any Obligation incurred after receipt of such written notice pursuant to a
written agreement entered into by Lessor prior to receipt of such notice.
<PAGE>

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 or remedy conferred by this Guaranty.

     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.
