     Junction SR 89A), complete. Any work provided for in change or extra work
     orders shall be performed in accordance with the foregoing division of work
     between the parties hereto, but if any work so ordered does not fall within
     the present bid items of the Construction Contract, it shall be performed
     in such manner as the parties may mutually agree. Each party hereto shall
     separately and individually enter into such subcontract, purchase orders,
     equipment rental agreements and shall employ sufficient workmen to enable
     it to perform the items of work as hereinabove divided between them in a
     diligent and satisfactory manner.

     The parties agree to split, in proportion to their respective shares of the
     work completed, all miscellaneous fees/charges necessary to establish the
     Joint Venture accounts.

         3.   The Parties agree that payment from the owner for work performed
     hereunder shall be made directly to the Joint Venture. The Joint Venture
     shall establish an account at a mutually acceptable financial institution,
     and management of said account shall be at the direction of the Management
     Committee established in paragraph 10 herein. Within three(3) days of the
     date that the funds are collected from the Owner by the Joint Venture, each
     Party shall be paid for the sums due them based on their portions of the
     Work completed as indicated in the progress estimates accompanying such
     payment less the appropriate amount of sales tax which will be paid from

     by the Parties in proportion to their respective shares of the work
     completed.

     Should any value engineering proposals be submitted, negotiated, and
     monetary gains realized by the Joint Venture for any work, the savings
     shall be divided between the partners in an equitable manner. In general,
     the division of any such gains should be commensurate with each parties
     risk, and participation in the entire change of scope to the project. It is
     agreed that, in all cases, the method of determining the division of any
     value engineering or cost reduction gain will be agreed upon prior to
     submittal of the proposal to the owner. In the event that an initial
     proposal changes significantly in scope through the course of discovery,
     the percentage split will be immediately reevaluated and agreed upon by
     both parties.

         In the event no agreement is reached prior to submittal, the following
     method of division will be implemented as a default:

                                                                               3
<PAGE>

         If changes in the scope of work affect only one party to this joint
     venture with no significant involvement of the other party, the affected
     party will receive full benefit from the monetary gain.

         If changes in the scope of work affect both parties to the joint
     venture, the benefit will be divided according to each parties share in the
     entire joint venture.

         4.  R. E. Monks and MVCI shall, and hereby do, assume all obligations
     of the Joint Venture under the Construction Contract with respect to the
     bid items assigned to them, respectively, as above provided, and each of
     them shall hold the other and the Joint Venture free and harmless from any
     and all liability or responsibility with respect to the bid items as so
     divided. With respect to Equal Employment Opportunity Affirmative Action
     Programs, Safety Programs and the like, each joint venturer shall be
     responsible for its respective part or proportionate share and shall
     undertake to satisfy all such requirements pertinent to the items of work
     assigned to it, at its own expense.

         5.  With respect to any bond or bonds required of the Joint Venture by
     Owner in connection with the Construction Contract, R. E. Monks and MVCI
     shall apply for and obtain such bonds and shall arrange for interests in
     the performance of the Construction Contract as the bid items thereof are
     hereinabove divided and the premiums for such bond or bonds shall be paid
     for by each Joint Venture partner respectively as outlined in attachment
     'A'.

         6.  Each Joint Venture partner shall procure, pay for, and maintain its
     own Workmen's Compensation, Automobile Liability, including owned, non
     owned, and hired automobiles, and Mobile Equipment Liability Policies.

         a.  A Comprehensive General Liability Insurance Policy with single
             limit coverage for each occurrence of:

             $1,000,000 including coverage for:

                    i.   Completed Operations and Products Liability
                    ii.  Broad Form Property Damage Liability, and
                    iii. Liability which such party may incur as a result of the
                         operations, acts or omissions of its

                                                                               4
<PAGE>

                         subcontractors, suppliers or materialsmen, and their
                         agents or employees,

         b.  Each party shall pay its proportionate share of the premium due for
             the above policy in the performance of the Construction Contract.
             The proportionate share is defined as the percentage of the total
             contract revenue that each party completes as defined in attachment
             'A'. It is anticipated that the cost of said premium will be 0.15%
             of the contract revenue.

         c.  The joint Venture Policy will name the parties as insured on the
             umbrella liability policy. The policy shall be written on an
             occurrence-type basis.

         8.  Each party shall furnish to the other party certificates from
     approved insurance companies evidencing that all the foregoing insurance is
     in force and will not be canceled, reduced or modified without thirty (30)
     days prior written notice to the other party. Such policies shall be
     endorsed to designate the other party hereto and this Joint Venture as
     additional insured.

         9.  Should any penalty be assessed because of delay in the completion
     of the work under said Construction Contract, such penalty shall be charged
     against the party assigned the particular item or items of the work which
     caused the delay in completion of the entire contract; and if both parties
     hereto should contribute to the delay, the penalty shall be charged or
     prorated to each of the respective parties in proportion to the respective
     items of work involved in the delay. Should penalties be assessed due to
     poor planning or decision making on the part of the mutually selected
     management personnel as described herein, such penalties will be charged
     proportionately between the parties as related to their share of the
     Construction Contract.

         10. Should any dispute arise between the parties hereto for any reason
     including the payment or division of any penalty or savings, such dispute
     shall first be attempted to be resolved by the Management Committee
     established in paragraph 13 herein. If the Management Committee cannot
     resolve the dispute, then the dispute shall be resolved as follows:

         a)  Partnering: Both parties will agree upon a facilitator and shall
         convene a partnering session which shall include the Management
         Committee, the Project Staff, and the Estimating/Support Staff from
         both companies. The session shall be conducted in accordance

                                                                               5
<PAGE>

         with the standard guidelines for partnering as established by the
         Arizona Department of Transportation and Maricopa County. The goal of
         the partnering session shall be to reach an equitable resolution of the
         dispute with the realization that Arbitration and/or Litigation can be
         very expensive and is therefore undesirable.

         b)  Arbitration: If the dispute cannot be resolved by Partnering then
     each of the parties hereto shall choose an arbitrator, and the two
     arbitrators so chosen shall select a third arbitrator. Each arbitrator
     shall be a person skilled and having knowledge and experience in
     construction work similar to this project. The Board of Arbitrators so
     chosen shall have full power to hear and determine all matters so in
     dispute, and their decision of an award when signed by two or more of them
     shall be final and conclusive as to all matters submitted to them and shall
     be binding upon both parties hereto.

         The expenses of any such arbitration shall be paid as follows:

         Each party shall pay the arbitrator chosen by such party, and the
     charges of the third arbitrator shall be paid equally by the parties
     hereto.

         11. Each party shall indemnify, defend and save harmless each other
     party, its members, directors, officers, and employees, from and against
     any and all claims, damages (including direct, liquidated, consequential,
     incidental or other damages), losses, liabilities, attorneys fees, costs
     and expenses whatsoever kind or nature at any time arising out of any
     failure of such party to perform any of its obligations with respect to the
     items of work by it to be performed or arising under this Joint Venture
     Agreement or which are in any manner directly or indirectly caused or
     occasioned by, or contributed to, any act, omission, fault or negligence,
     whether active or passive, in whole or in part, of anyone acting under its
     direction or control, or on its behalf in connection with or incidental to
     such work, even though the same may have resulted from the joint,
     concurring or contributory act, omission, fault or negligence, whether
     active or passive, or the other party, Owner or any other person, unless
     the same is caused by the sole negligence or willful misconduct of the
     other party, its agents, servants or independent contractors who are
     directly responsible to it.

         12. R. E. Monks and MVCI each shall furnish all working capital, when
     and as required, for the prosecution of the bid items to be performed by
     them, and by reason thereof it is not contemplated that

                                                                              6
<PAGE>

     the Joint Venture will itself require any working capital. Each party shall
     be entitled to the profit and shall bear the loss, if any, with respect to
     each bid item of work assigned to it. Each of the parties shall maintain
     adequate books of account with respect to its operations. The Joint Venture
     shall request securities in lieu of retention and each party shall fund his
     proportionate share. Earnings from the securities account will be
     distributed to each party in proportion to its respective funding amount at
     the time of earnings distribution.

         13.  MVCI shall be the sponsor of this Joint Venture and the Managing
     Party with respect to all work to be performed under the Construction
     Contract. MVCI is authorized to execute, on behalf of the Joint Venture,
     all contracts and any related documents. R. E. Monks and MVCI shall be
     responsible for the overall prosecution, scheduling and coordination of the
     work to be performed under the Construction Contract, but shall not be
     entitled to a fee therefore. The Project Manager, shall be employed by MVCI
     but will be mutually agreed upon by both parties. This employee shall act
     on behalf of and in the best interest of the Joint Venture without regard
     to their employment by either party.

         To facilitate handling of matters and questions in connection with the
     performance of the Contract and the Work, a Management Committee of three
     persons will be created consisting of one appointee from each Party and the
     Project Manager. Each of the Parties shall advise the other in writing as
     to the name of the person appointed by it as its representative in the
     Management Committee. Each Party may, at any time and from time to time,
     change its representative by filing with the other written notice of such
     change. The said representatives shall meet from time to time, as necessary
     to act on all necessary matters pertaining to the work of the Joint
     Venture. The Parties shall endeavor to reach unanimous decisions on all
     matters. In the event that unanimity is not reached, either party may
     request a resolution as described in paragraph 10.

         If at any time one of the venturers has reasonable cause to suspect
     that any employee, of either party or subcontractor or supplier, is acting
     in a manner that is unsafe or otherwise injurious to the welfare of the
     Joint Venture (including the parties thereto and their employees), as
     managing partner, MVCI will be responsible to act in a responsible and
     timely fashion to counsel, remove, or otherwise correct the situation. This
     responsibility to correct these situations does not

                                                                               7

     however change MVCI liabilities from those described herein in any way.

         14.  This Joint Venture Agreement extends only to the performance of
     the Construction Contract, including any extra work orders, and/or change
     orders in connection therewith, or any contract supplemental thereto. In no
     event shall this agreement extend to or cover any other or different work,
     and upon the completion of performance of the Construction Contract and the
     distribution by the Joint Venture to the Joint Venturers of the payments
     from Owner as herein provided, the Joint Venture shall terminate.

         15.  If any party hereto (if any individual) shall die or become
     incompetent, or if any party (not an individual) shall dissolve, or if any
     party hereto shall become bankrupt, or file a voluntary petition in
     bankruptcy, this Joint Venture shall not terminate, but the right of the
     disabled party to continue to participate in the Joint Venture shall,
     except as hereafter provided, terminate, and the remaining parties shall do
     all things necessary to complete performance of the Construction Contract
     and then to wind up all of the Joint Venture affairs, including the
     collection of all monies and property due this Joint Venture and the
     distribution of its assets. The disabled party, or its representative,
     shall have no further voice in the performance of the Construction Contract
     or in the management of this Joint Venture. The disabled party, shall be
     entitled to that share of the profits of this Joint Venture earned with
     respect to the items of work assigned to the disabled party measured by the
     ratio of dollar value of the items of work performed by such party in
     relation to the total dollar value of all of such items, but such disabled
     party and its representatives shall be charged with and shall be liable for
     its full share of any and all losses that may be suffered by this Joint
     Venture with respect to the entirety of all items of work assigned to the
     disabled party.

         16.  Any assignment of this agreement, in whole or in part, or any
     transfer of any rights hereunder, or any delegation of any duties to be
     performed hereunder, made by either party hereto, whether by operation of
     law or otherwise, without the prior written consent of the other party
     hereto shall be void.

         17.  Subject to the foregoing provisions, this agreement shall insure
     to the benefit of and be binding upon the parties hereto, their heirs,
     successors, assigns and legal representatives.

                                                                               8

         18.  As used herein, the neuter gender includes the masculine or

     State of Arizona. Venue shall be Maricopa County, Arizona unless otherwise
     specifically agreed between parties. If in the event any provision of this
     agreement is found to be unenforceable, the remaining provisions shall
