and off-site infrastructure improvements, constructing the Homes, marketing the

     D.   Provided that Owner delivers fully entitled Lots to Builder together
with all of the financing and bonding in amounts and at the time required to

to the terms and conditions set forth in this Agreement.

     NOW, THEREFORE,   in reliance on the facts set forth in the above recitals
and in consideration of the mutual covenants and agreements set forth herein,
the parties hereto agree as follows:

     1.  Engagement.
         ----------

     Owner hereby engages the services of Builder to develop and construct the
Project and market the Homes, and Builder hereby agrees to accept such
engagement and provide said services to Owner for the consideration and upon the

     2.  Development of the Project and Marketing of the Homes.
         -----------------------------------------------------

     Builder agrees to diligently develop and construct the Project and market

circumstances that exist from time to time during the term hereof to perform its
services hereunder in a manner that, subject to the rights of Owner to direct
Builder and subject to the performance of Owner of its obligations (particularly
funding) hereunder, shall be intended to maximize the sales revenue from the
completed Homes.

     3.  Term.
         ----

improvements (the "Phase Budget" herein).  Within Five (5) business days
following receipt by Owner of the proposed Phase Budget, Owner shall notify
Builder of Owner's approval or disapproval of the same, which approval Owner
shall not unreasonably withhold.  Failure of Owner to notify Builder in writing

If all or any portion of the proposed Phase Budget is disapproved, the parties
shall meet as soon as reasonably practicable thereafter to endeavor in good
faith to reach agreement on the Phase Budget.  Builder shall not make any
commitment or contract which is materially (more than 10%) more in cost for a
line item than as set forth for said line item in the Phase Budget as it may be
amended from time to time without the prior written consent of Owner which
consent Owner shall not unreasonably withhold.  Builder shall submit to Owner a
new Phase Budget for each Phase of the Project which new Phase Budget shall be
reviewed and reasonably approved by Owner and followed by Builder as provided
herein.

conformity with the Phase Budget. Builder shall hold monthly job cost meetings
with representatives of the Owner and shall prepare monthly updates of the phase
Budget with variance explanations and Project cost reports

                                       2.
<PAGE>

showing actual expenditures made during such month and from the beginning of the
phase to date, by category of expenditures, and a comparison thereof to budgeted
expenses and estimated cost of completion of the improvements. Revised Phase

subcontractor payment.

     6.   Phase Schedule.
          --------------

                -----------------------
proposed Phase Budge, Builder shall submit to Owner, for Owner's review and
reasonable approval, the proposed schedule for the design and construction of

unreasonably withhold, and the Phase Schedule shall be approved and updated for
each Phase in the same manner as the Phase Budget.

          (b)   Conformity with Phase Schedule.  Builder shall use its
                ------------------------------

conformity with the Phase Schedule. Builder shall prepare and deliver to Owner
monthly progress reports setting forth the actual construction progress achieved
during such month and from the beginning of the Phase to date, and comparison
thereof to scheduled construction progress for the same period and sales reports

therefor furnished by Owner to Builder.

     8.   Phasing of Development.
          ----------------------

          Owner and Builder hereby agree that to minimize the financial risk to
Owner, Builder shall develop the Project in phases, with a phase typically (but
not limited to) approximately ten (10) to twenty (20) Homes (a "Phase" herein).
Accordingly, Builder shall submit all budgets and schedules required pursuant to
this Agreement on a Phase-By-Phase basis.  Budgets and schedules shall set forth
Builder's estimates of the proper allocation to particular phases of those items
which impact more than one phase of the project.

<PAGE>

connection with the Project, to require the replacement of any defective or
improper work, and to refuse payment of any funds until such matters have been
remedied. Inspections by Owner shall not in any manner constitute Owner's
approval or acceptance of the progress or quality of the work. The failure of

     15.  Approvals by Owner.
          ------------------

entity whether the change has been requested by the entity either orally or in
writing. Builder shall furnish all such items from time to time to Owner and, if
Owner fails to notify Builder in writing within Five (5) business days of
receipt of such item in question shall be deemed to be approved by Owner.

     16.  Land Maintenance and Protection.
          -------------------------------

          During the term of this Agreement, Builder shall, at the sole cost of
Owner, maintain the property free of weeds, debris, pests and toxic or hazardous

In addition, Builder shall, at the sole cost and expense of Owner, at all times
take such actions as are reasonably necessary to protect the Project and all
improvements thereon, whether or not completed, from being damaged by the work
of Builder or any subcontractor or other persons or cause including, but not
limited to, vandals and the elements.

     17.  Liens.
