     NOW THEREFORE, in consideration of the promises and the mutual agreements,
covenants, and provisions contained in this Agreement, APM and Vulcan agree and
declare as follows:

     1. GRANT. APM hereby leases and grants to Vulcan the sole and exclusive
lease and use of the Leased Property. APM shall lease and let the Leased
Property exclusively to Vulcan. During the term of the Agreement, Vulcan shall
have the right to conduct all operations necessary and incident to its
installation and operation of the Asphalt Plant, to purchase Mineral Products
from APM pursuant to the terms of this Agreement and to have such access to the
Leased Property as it reasonably requires to carry out its permitted activities

<PAGE>

the purposes stated herein. APM also grants to Vulcan the right to extend and
modify the Leased Property to accommodate the Ready Mix Plant at any time during
the term of this Agreement. Vulcan's decision to install the Ready Mix Plant
will be accomplished by an amendment to this Agreement by APM and Vulcan
modifying the Site Plan (in accordance with Section 4(b)) to include additional
acreage and to correspondingly increase the Property Rent (described in Section
3(c)(i)) on a pro-rata basis per the additional acreage.

     2. TERM, RENEWAL AND EFFECTIVE DATE.

     (a) TERM. This Agreement shall be for a term of five years commencing on
the effective date hereof.

     (b) RENEWAL Vulcan may renew this Agreement for two (2) five year periods
by sending written notice of its election to renew to APM not less than ninety
(90) days prior to the expiration of any term of this Agreement.

     3. RENT, PLANTS, MINERAL PRODUCTS AND PAYMENTS.

     (a) ASPHALT PLANT AND READY MIX PLANT. Vulcan shall be solely responsible
for all aspects of the acquisition, installation, operation and maintenance of
the Asphalt Plant. Vulcan shall have the right, but not the obligation, to
install and operate the Ready Mix Plant on the modified Leased Premises during
the term of this Agreement, and in such event, Vulcan shall be solely
responsible for all aspects of the acquisition, installation, operation and
maintenance of the Ready Mix Plant.

     (b) MINERAL PRODUCT. Each 12 month period that this Agreement is in effect,
commencing on the Effective Date, APM guarantees, warrants and represents that
it will produce not less than 250,000 tons of Mineral Products which will meet
or exceed the written specifications set forth by Vulcan and delivered to APM.
Consequently, Vulcan agrees to accept and purchase at least 250,000 tons per
year of Mineral Products derived from the Mineral Estate and the BLM Contract.
Subject to subsection 3(c)(ii) below, if APM produces more than 250,000 tons of
Mineral Products, Vulcan shall have the right, but not the obligation to
purchase such materials in accordance with this Agreement. The Mineral Products
shall strictly conform to Vulcan's standards and specifications for the Asphalt
Plant and, if applicable, the Ready Mix Plant.

     (c) CONSIDERATION.

          (i) PROPERTY RENT. Vulcan shall pay APM the sum of Two Thousand Five
Hundred Dollars ($2,500.00) each month that this Agreement is in effect. The
rental payment shall be delivered to APM on the first day of each such month and
shall not be deemed overdue until ten (10) days following written notice from
APM. Rent for partial months at the inception or the termination of this
Agreement shall be prorated.

          (ii) TONNAGE ROYALTY. Vulcan agrees to purchase from APM, at the rate
of XXXXX ($XXX) per ton ("Purchase Price"), all of the Mineral Products
necessary for Vulcan to operate its Asphalt Plant and if applicable, the Ready
Mix Plant. The amount of Mineral Products purchased by Vulcan shall not be less
than the 250,000 tons per year referenced above. If Vulcan determines that APM
is unable to provide Vulcan with sufficient quantities of materials, Vulcan may
obtain any additional minerals and aggregates from outside sources. For the life
of the Agreement and all extensions, any deliveries of Mineral Products ordered
by Vulcan and delivered and/or picked up by a Vulcan client shall be counted
towards fulfillment of Vulcan's guaranteed 250,000 annual minimum requirement
and will be billed by APM to Vulcan at the Purchase Price.

          (iii) HOPPER LOADING FEE. APM shall provide sufficient and suitable
front-end loaders and other necessary machinery and operators to provide the
Mineral Product deliveries described herein to the hoppers designated by Vulcan
at the Asphalt Plant and, if applicable, the Ready Mix Plant.

                                        2
<PAGE>

Vulcan shall pay APM Twenty Five Cents ($.25) for each ton of Mineral Product
delivered to the hoppers pursuant to this Agreement (the "Hopper Loading Fee").

          (iv) ADJUSTMENTS. Beginning with the first (1st) anniversary of the
Effective Date, and on every anniversary thereafter throughout the term of this
Agreement and any renewal term (the "Adjustment Dates"), the Purchase Price and
Hopper Loading Fee may be reviewed and adjusted by APM. The adjustment shall be
based upon the Producer Price Index for Sand and Gravel, Western Region,
Mountain, (Product Code 1442-38) (Base year 1982-100), published by the United
States Department of Labor, Bureau of Labor Statistics ("PPI"), which is
published for the month of December, 2005 ("Base PPI"). The PPI published for
the month, which is three (3) months prior to the month in which the Adjustment
Date in question occurs ("Adjustment PPI") shall be used in determining the
amount of the adjustment. If adjusted, the Purchase Price and Hopper Loading Fee
for each one (1) year period commencing with an Adjustment Date shall be the
result of multiplying $XXXX (in the case of the Purchase Price) and $0.25 (in
the case of the Hopper Loading Fee) by a fraction, the numerator of which is the
Adjustment PPI and the denominator of which is the Base PPI, provided that in no
event shall the Purchase Price or Hopper Loading Fee be increased by more than
three percent (3%) above the amount payable during, the period immediately
preceding the Adjustment Date or be less than the amount payable during the
period immediately preceding the Adjustment Date. Should the Bureau of Labor
Statistics discontinue the publication of the PPI, or publish the PPI less
frequently, or alter the PPI in some other manner, then APM and Vulcan shall
agree on a substitute index or substitute procedure which reasonably reflects
and monitors sand and gravel producer prices. Before any adjustment is
implemented, APM will review said adjustments with Vulcan at least 60 days prior
to any price change.

          (v) PREFERENTIAL PRICING. In the event APM sells Mineral Product to
any third parties unrelated to Vulcan during the term of this Agreement, the
price that APM charges such third parties for the Mineral Product shall be no
less than five percent (5%) greater than the then existing Purchase Price.

     (d) PAYMENTS.

          (i) PAYMENT AND DELIVERY. At the end of each month that this Agreement
is in effect, APM shall deliver to Vulcan an invoice comprised of each Vulcan
Statement and the APM Statement for the prior month less any Preferential
Pricing reductions pursuant to Section 3(c)(v). The invoice shall be due and
payable by Vulcan to APM within 30 days of Vulcan's receipt thereof. Interest
will accrue at the rate of 1.5% per month if the invoice is not timely paid.

All payments required hereunder may be mailed to APM's mailing address of c/o
Western Power & Equipment, 6407-B Northeast 117th Avenue, Vancouver, WA 98662 or
to any single depository as the parties may instruct. The delivery or the
deposit in the mail of any payment hereunder on or before the due date thereof
shall be deemed timely payment hereunder.

          (ii) CALCULATION. Payments for Mineral Products delivered to the
Asphalt Plant shall be calculated in the following manner: The Purchase Price
shall be determined by the actual weight of Mineral Products ordered by Vulcan
and delivered to the Asphalt Plant and, if applicable, the Ready Mix Plant. Each
delivery shall be weighed in Vulcan's production scales located on the Leased
Property and shall be recorded in Vulcan's records. Vulcan shall deliver APM a
statement detailing the weight of Mineral Products used in production at the
Asphalt Plant for each day of operation during the term of this Agreement (each
a "Vulcan Statement"),

Payments for Mineral Products delivered to Vulcan's off-Property facilities or
customers shall be calculated in the following manner: Vulcan's or its agents'
trucks picking up Mineral Product shall be weighed on APM's truck scales located
adjacent to the Property. APM shall keep daily summary sheets detailing the
total weight of Mineral Products ordered by Vulcan and delivered to Vulcan's off
Property facilities or customers each day. At the end of each month, APM shall
submit an invoice to Vulcan based on APM's summary sheets for that month (each
an "APM Statement").

Plant, Vulcan shall prepare a site plan delineating the exterior boundaries of
the Leased Property and the location and specifications of the Asphalt Plant and
related improvements and equipment ("Site Plan") and shall submit the Site Plan
to APM for approval, which approval shall not be unreasonably withheld. Within
ten (10) days after receipt of the Site Plan, APM shall deliver written notice
to Vulcan specifying that it agrees to the Site Plan or that it has suggested
changes to the Site Plan, in which case such notice shall specifically detail
any requested changes. If APM requests changes, the parties shall promptly meet
and work together in good faith to agree on the Site Plan, Vulcan shall then
resubmit the Site Plan to APM and the parties shall follow the same procedure
set forth above until the Site Plan is approved by both parties. If after four
(4) months following the initial submission of the Site Plan to APM, the Site
Plan has not been approved in a manner adequate to Vulcan, in Vulcan's sole and
absolute discretion, Vulcan may terminate this Agreement upon written notice to
APM. Both APM and Vulcan shall retain copies of the Site Plan. The Site Plan may
not be amended or changed without the approval of both APM and Vulcan. Upon
approval of the Site Plan by Vulcan and APM, the Site Plan shall be deemed the
correct delineation of the Leased Property and shall be substituted in Exhibit
A.

     9. BREACH, NOTICE AND REMOVAL OF IMPROVEMENTS.

     (a) BREACH. The failure of either party to fully perform under any or all
of the material terms and conditions of this Agreement shall constitute a breach
of this Agreement entitling the offended party to any and all such action
provided by law, including, but not limited to, one or more of the following:
(1) Declare the Agreement at an end and terminated and/or (2) sue for the full
balance due under the Agreement (with a duty to mitigate), and any damages
sustained by the offended party.

     (b) NOTICE. Any breach alleged under this Agreement shall be preceded by a
thirty (30) day written notice of the same to the defaulting party, If the
defaulting party shall exercise in good faith diligent efforts within such
thirty (30) day period to cure the failure specified in the notice but shall not
be able to do so because of the nature of the failure, acts of God, riots, or
labor strikes, then any such failure shall not be considered a breach or default
as long as the defaulting party shall continue to exercise in good faith such
diligent efforts to cure such failure and shall do so within a reasonable period
of time,

     (c) REMOVAL OF IMPROVEMENTS. Upon any termination or expiration of this
Agreement, Vulcan shall have a period of one hundred twenty (120) days from and
after the effective date of termination within which it must remove from the
Property all of its machinery, buildings, structures, facilities, equipment and
other property of every nature and description erected, placed or situated
thereon, except supports placed in shafts, drifts, or openings in the Property
("Vulcan Assets"). Failure of Vulcan to use diligent efforts to remove the
Vulcan Assets within such period shall constitute an abandonment by Vulcan to
APM of the same; provided, however, that Vulcan may still be required to remove
the Vulcan Assets upon notice from APM, which notice shall be given within
thirty (30) days following termination of the Agreement. APM may also, within
fifteen (15) days after its receipt of notice of termination by Vulcan, elect to
purchase any permanent structures placed on the Property by Vulcan. The purchase
price shall be determined by an independent appraiser mutually satisfactory to
the parties which appraisal shall be final. APM shall tender the amount of such
appraisal in legal tender of the United States within thirty (30) days after
completion of the appraisal regardless of whether APM purchases the structures.

If, but only if APM has notified Vulcan in writing that removal of the Vulcan
Assets is required in accordance with the foregoing paragraph, Vulcan shall
continue to pay APM the monthly rent specified in Section (3)(c)(i) as long as
Vulcan's assets remain on the Property after termination of this Agreement;
provided, however, that Vulcan shall pay APM the sum of Three Thousand Seven
Hundred Fifty Dollars ($3,750.00) for each month that the Vulcan Assets remain
on the Property after the 120 day period.

     10. RIGHT OF FIRST REFUSAL. If APM, or APM's heirs, executors, grantees,
successors or assigns, at any time during the Term of this Lease or any
extension thereof, receive an offer to purchase any of APM's real property,
assets and liabilities located in Pinal County, State of Arizona ("Pinal
Property"), and APM desires to accept such offer; or should APM during any such
time make an offer to sell any of the Pinal Property, APM shall give Vulcan
thirty (30) days notice in writing of such offer setting forth the name and
address of the proposed purchaser, the amount of the proposed purchase price,
and all other terms and conditions of such offer, and Vulcan shall have the
first option to purchase the Pinal Property which is the subject of the offer by
giving written notice to APM of its intention to purchase within said thirty
(30) day period at the same price and on the same terms of any such offer, it
being understood that in the event Vulcan does not give notice of its intention
to exercise such option to purchase within such period, (i) this Agreement and
all of its terms and conditions shall nevertheless remain in full force and
effect and APM and any purchaser or purchasers of the Property, shall be bound
thereby, and (ii) APM shall not sell any of the Pinal Property on terms and
conditions more favorable than those contained in the offer presented to Vulcan.
In the event that the Final Property set forth in the offer is not sold for any
reason, Vulcan shall have, upon the same conditions and notice, the continuing
right of first refusal to purchase the Pinal Property or any part thereof upon
the terms of any subsequent offer or offers to purchase.

     11. CONFIDENTIALITY. APM and Vulcan agree that all information, documents
and other materials exchanged by and between themselves pursuant to this
Agreement shall be used solely for the purposes of pursuing the goals of this
Agreement, and that such information, documents and other

                                        7

representatives. Vulcan agrees that it will not enter into any contractual
arrangement with the Bureau of Land Management, United States Department of the
Interior or with the State of Arizona Land Department to acquire an interest or
right in the land or minerals contained in Parcels 1, 2 or 3.

     12. QUIET ENJOYMENT. APM covenants and agrees that Vulcan shall have the
peaceful and quiet possession and enjoyment of the Leased Property for the
conduct of its business operations during the term of this Agreement, without
hindrance by APM or any party whatsoever.

     13. NONDISTURBANCE. This Agreement is contingent upon APM providing to
Vulcan a non-disturbance agreement from its existing lender(s) (if any), which
states that the right of possession of Vulcan to the Property shall not be
affected or disturbed by any mortgagee or deed of trust holder in the exercise
of any of its rights under a deed of trust, mortgage or the note secured
thereby, and any sale of the Property pursuant to the exercise of any rights and
remedies under a mortgage, deed of trust or otherwise shall be made subject to
Vulcan's right of possession to the Property under this Agreement.

     14. NON-COMPETITION. APM and its affiliates will not directly or indirectly
own, manage, operate, join or control an Asphalt Plant within Pinal County,
Maricopa County, or Pima County, Arizona ("Territory") or allow any third party
to operate an Asphalt Plant on property owned, leased, licensed or permitted by
APM within the Territory, at any time during the term of this Agreement APM and
its affiliates will not directly or indirectly own, manage, operate, join or
control a Ready Mix Plant within the Territory or allow any third party to
operate a Ready Mix Plant on property owned, leased, licensed or permitted by

provided, however, in the event Vulcan does not provide written notice to APM of
its intent to construct and operate a Ready Mix Plant on the Leased Property (or
expanded Leased Property) within eighteen (18) months following the Effective
Date, APM may seek to install and operate no more than one (1) Ready Mix Plant
on the APM Property (as defined in Recital D). Notwithstanding the foregoing,
Vulcan may still construct and operate a Ready Mix Plant in accordance with this
Agreement regardless of whether it notifies APM of such intent within the
aforementioned time period. APM expressly agrees that the geographic
restrictions contained herein are reasonable in its scope and geographic
restraints.

     15. LIMITATION OF LIABILITY. No constituent member, partner or shareholder
in or agent of Vulcan or APM, nor any advisor, trustee, director, officer,
employee, beneficiary, shareholder, member, partner, participant, representative
or agent of any partnership, limited liability company, corporation, trust or
