                                                      DPR Construction, Inc.
                                                     DPR Job No.: 09-9600140
                                           Subcontract No. 09-96001-00-048-S
                                                   Cost Code: See Section 26

      will facilitate the efficient completion of the entire work.  In the
      event Subcontractor fails to maintain its part of the Contractor's
      schedule, it shall, without additional compensation, accelerate the
      work as Contractor may direct until Subcontractor's work is in
      accordance with such schedule.  Contractor shall have complete control
      of the premises on which the work is to be performed and shall have the
      right to decide the time and order in which various portions of the
      work shall be installed and the relative priority of the work of 
      Subcontractor and other subcontractors, and, in general, all other
      matters pertaining to the timely and orderly conduct of the work of
      Subcontractor on the premises.  Should Subcontractor be delayed in the
      prosecution or completion of the work by the act, neglect or default of
      Owner, Architect or Contractor; or should Subcontractor be delayed
      waiting for materials, if required by this Contract to be furnished by
      Owner or Contractor; or by damage caused by fire or other casualty for
      which Subcontractor is not responsible; or by the combined action of
      the workmen, in no way caused by or resulting from fault or collusion
      on the part of Subcontractor; or in the event of a lock-out by
      Contractor; then the time herein fixed for the completion of the work
      shall be extended by the number of days that Subcontractor has thus
      been delayed.  But no allowance or extension shall be made unless a
      claim therefor is presented in writing to Contractor within 48 hours of
      the commencement of such delay, and under no circumstances shall the
      time of completion be extended to a date which will prevent Contractor
      from completing the entire project within the time allowed Contractor
      by Owner for such completion.

      No claims for additional compensation or damages for delays, whether
      caused in whole or in part by any conduct on the part of Contractor,
      including, but not limited to, conduct amounting to a breach of this
      Agreement, or delays by other subcontractors or Owner shall be
      recoverable from Contractor, and the above-mentioned extension of time
      for completion shall be the sole remedy of Subcontractor; provided,
      however that in the event Contractor obtains additional compensation
      from Owner on account of such delays, and in the event Subcontractor
      shall have satisfied all subcontract and contract requirements with
      respect to timely notification and assertion of claims and with respect
      to cooperation with Contractor in the prosecution therewith,
      Subcontractor shall be entitled to such portion of the additional
      compensation so received by Contractor from Owner as is deemed by the
      Contractor to be equitable under all of the existing and applicable
      circumstances.  In no event shall compensation to Subcontractor for
      delay damages exceed that which Contractor receives from Owner on
      Subcontractor's behalf.  In the event that Contractor prosecutes a
      claim against Owner for additional compensation for any delay,
      Subcontractor shall cooperate fully with Contractor in the prosecution
      thereof and shall pay costs and expenses incurred in connection
      therewith, including actual attorneys' fees, to the extent that said
      claim is made by Contractor at the request of Subcontractor.

      Subcontractor shall prepare and obtain approval as required by the
      Contract Documents for all shop drawings details, samples, and do all
      other things necessary and incidental to the prosecution of its work in
      conformance with Contractor's progress schedule.

      See SECTION 26 for additional TIME provisions.<PAGE>

SECTION 6.  CHANGES IN THE WORK
            -------------------

      Subcontractor shall make any and all changes in the work described in
      the Contract Documents and this Agreement as directed by Contractor in
      writing.  Such change or written direction shall not invalidate this
      Agreement.

      If necessary, the contract price stated in Section 3 and the time for
      Subcontractor's performance shall be adjusted by appropriate additions
      or deductions mutually agreed upon before Subcontractor performs the
      changed work.  Subcontractor shall supply Contractor with all
      documentation necessary to substantiate the amount of the addition to
      or deduction from the price or time.  If Contractor and Subcontractor
      cannot agree on the amount of the addition or deletion.  Subcontractor
      shall nonetheless timely perform the work as changed by Contractor's
      written direction.  Once Subcontractor receives Contractor's written
      direction, Subcontractor is solely responsible for timely performance
      of the work as changed by the written direction.  In any event,
      Subcontractor's compensation for changes in the work shall be limited
      to that which Contractor receives from Owner on Subcontractor's behalf.

      Payment for changed work shall be made in accordance with Section 4.

      Subcontractor shall not make any changes in the work described in
      Section 2 or in any way cause or allow that work to deviate from the
      Contract Documents without written direction from Contractor.  If
      Subcontractor makes any changes in the work described in Section 2
      without written direction from Contractor, such change constitutes an
      agreement by Subcontractor that it will not be paid for that changed
      work, even if it received verbal direction from Contractor or any form
      of direction, written or otherwise, from Owner or any other person or
      entity.  In addition, Subcontractor shall be liable for any and all
      losses, costs, expenses, damages, and liability of any nature
      whatsoever associated with or in any way arising out of any such change
      it makes without written direction from Contractor.

      If a dispute arises between Contractor and Subcontractor about whether
      particular work is a change in the work described in Section 2,
      Subcontractor shall timely perform the disputed work and may give
      written notice of a claim for additional compensation for that work. 
      Such written notice of claim must be given within ten (10) days after
      such work is performed.  Subcontractor's failure to give written notice
      within the ten (10) days constitutes an agreement by it that it will
      not be paid for the disputed work.

      No change, alteration, or modification to or deviation from this
      Agreement, the Contract Documents, prime contract, plans, or
      specifications, whether made in the manner provided in this provision
      or not, shall release or exonerate, in whole or in part, any bond or
      any surety on any bond given in connection with this Agreement, and no
      notice is required to be given to such surety of any such change,
      alteration, modification, or deviation.

SECTION 7.  DAMAGES CAUSED BY DELAYS OF SUBCONTRACTOR
            -----------------------------------------

      If Subcontractor should default in performance of the work described in
      Section 2 or should otherwise commit any act which causes delay to the
      prime contract work, Subcontractor shall be liable for all losses,
      costs, expenses, liabilities and damages, including consequential
      damages and liquidated damages, sustained by Contractor, or for which
      Contractor may be liable to Owner or any other party because of
      Subcontractor's default.

SECTION 8.  BONDING OF SUBCONTRACTOR
            ------------------------

      Concurrently with the execution of this Agreement, Subcontractor shall,
      if required by Contractor, execute a labor and material bond and
      performance bond, in an amount equal to one hundred percent (100%) of
      the Contract Price.  Said bonds shall be executed by a corporate surety
      acceptable to Contractor and shall be in a form satisfactory to
      Contractor.  Contractor shall pay the premium on said bonds unless
      otherwise provided herein or in the Contract Documents.

SECTION 9.  LIENS

      In case suit is brought on any claim or liens for labor performed or
      material used on or furnished to the project, Subcontractor shall pay

      decision of the court in said suit Subcontractor agrees within ten (10)
      days after written demand to cause the effect of any such suit or lien
      to be removed from the premises, and in the event Subcontractor shall
      fail so to do.  Contractor is authorized to use whatever means in its
      discretion it may deem appropriate to cause said lien or suit to be
      removed or dismissed and the cost thereof, together with actual
      attorneys' fees, shall be immediately due and payable to Contractor by
      Subcontractor. Subcontractor may litigate any such lien or suit
      provided it causes the effect thereof to be removed, promptly in
      advance, from the premises, and shall further do such things as may be
      necessary to cause Owner not to withhold any monies due to Contractor
      from Owner by reason of such liens or suits.

      It is understood and agreed that the full and faithful performance of
      this Agreement on the part of Subcontractor including the payment of
      any obligations due from Subcontractor to Contractor, and any amounts
      due to labor or materialmen finishing labor or material for said work)
      is a condition precedent to Subcontractor's right to receive payment
      for the work performed, and any monies paid by Contractor to
      Subcontractor under the terms of this Agreement shall be impressed with
      a trust in favor of labor and materialmen furnishing labor and material
      to Subcontractor on the work herein subcontracted.

                                                   Cost Code: See Section 26

14.1.2 Termination for Default.  If Subcontractor fails to commence and
       satisfactorily continue correction of a default within forty-eight
       (48) hours after receipt by Subcontractor of the notice issued under
       Section 14.1.1., then Contractor may terminate Subcontractor's right
       to perform under this Agreement and use any materials, implements,
       equipment, appliances or tools furnished by or belonging to
       Subcontractor to complete Subcontractor's work without any further
       compensation to Subcontractor for such use.  Contractor also may
       furnish those materials and equipment, and/or employ such workers or
       subcontractors as Contractor deems necessary to maintain the orderly
       progress of the work.

       In such case.  Subcontractor shall be entitled to no further payment
       until the balance of Subcontractor's work has been completed.  At that
       time, all of the costs incurred by Contractor in performing
       Subcontractor's work, including a markup of fifteen percent (15%) for
       overhead and profit on such expenses, plus actual attorneys' fees as
       provided above, shall be deducted from any monies due or to become due
       Subcontractor.  Subcontractor shall be liable for the payment of any
       amount by which such expenses may exceed the unpaid balance of the
       Contract Price.

14.1.3 Termination for Convenience.  Contractor may at any time and for any
       reason terminate Subcontractor's services and work at Contractor's
       convenience.  Cancellation shall be by service of written notice to
       Subcontractor's place of business.

       Upon receipt of such notice, Subcontractor shall, unless the notice
       directs otherwise, immediately discontinue the work and placing of
       orders for materials, facilities and supplies in connection with the
       performance of this Agreement, and shall, if requested, make every
       reasonable effort to procure cancellation of all existing orders or
       contracts upon terms satisfactory to Contractor or at the option of
       Contractor, give Contractor the right to assume those obligations
       directly, including all benefits to be derived therefrom. 
       Subcontractor shall thereafter do only such work as may be necessary
       to preserve and protect the work already in progress and to protect
       material and equipment on the job site or in transit thereto.

       Upon such termination, Subcontractor shall be compensated only as
       follows, subject to deduction for previous payments: (1) for the
       actual cost of the work completed in conformity with this Agreement
       and having been approved by Contractor as having been made or incurred
       in performing under this subcontract; and, (2) such other costs
       actually included by Subcontractor as are permitted by the prime
       contract and approved by Owner in settling or discharging outstanding
       commitments entered into by Subcontractor in performing under this
       Subcontract; and (3) profit, insofar as a profit is actually realized
       hereunder, and in an amount equal to the profit on the entire
       Subcontract estimated, based on actual cost performance, at the time
       of termination, multiplied by the percentage of completion of the
       work.  In no event, however, will the compensation to Subcontractor
       exceed the total Subcontract price less payments previously made and

       less the contract price of work not terminated.  Subcontractor shall
       not be entitled to any claim or claim of lien against Contractor or
       Owner for any additional compensation or damages in the event of such
       termination and payment.

14.1.4 Grounds for Withholding Payment.  Contractor may withhold, or on
       account of subsequently discovered evidence, nullify the whole or part
       of any payment to the extent necessary to protect Contractor from
       loss, including costs and attorneys' fees, on account of (1) defective
       work not remedied; (2) claims filed or reasonable evidence indicating
       probable filing of claim; (3) failure of Subcontractor to make
       payments properly to its subcontractors or for material, labor or
       fringe benefits; (4) a reasonable doubt that this Agreement can be
       completed for the balance then unpaid; (5) damage to another
       subcontractor; (6) penalties assessed against Contractor or

            time limits.

14.2.2 Interim Remedies.  If Subcontractor is not performing in accordance
       with the schedule of work at the time of entering an order for relief,
       or at any subsequent time, Contractor, while awaiting the decision of
       Subcontractor or its trustee to reject or to accept this Agreement and
       provide adequate assurance of its ability to perform hereunder, may
       avail itself of such remedies under this Section as are reasonably
       necessary to maintain the schedule of work.
