                           schedule dictates, or

                  2.       If Subcontractor, in Terremark's opinion, falls
                           behind in the schedule due to, lack of competent

will be immediately' refunded to the subcontractor, less any additional general
condition costs and/or direct costs of other trades incurred by Terremark due
delay.

         2.7 Terremark if it deems necessary, may direct the Subcontractor to
work overtime. If so instructed by Terremark, Subcontractor will work said

provision herein, Terremark will pay the Subcontractor for the actual premium on
wages paid, at rates which have been approved by Terremark, plus taxes imposed

                  1.       If Subcontractor fails to begin and continue the Work
                           on the specific day that the current progress
                           schedule dictates, or

                  2.       If Subcontractor, in Terremark's opinion, falls

                           personnel, lack of materials, lack of, subcontractor
                           cooperation, etc.

necessary to avoid delay in the completion of the building.

taxes imposed by law and based upon labor performed, materials furnished or
services rendered, including, but not limited to, payroll taxes, sales taxes,

Subcontractor arising out of either the acquisition by the Subcontractor or by
any of its subcontractors of materials, equipment, or any other kind of personal
property, or the furnishing of labor and/or services in connection with the
Work. Where the law requires any such tax to be stated and charged separately,
the total of all items included within the Work and the added tax shall not
exceed the Contract Consideration state herein.

         3.3 The parties hereto specifically agree that a condition precedent to
all payments to be made by Terremark to Subcontractor, including the final
payment, is the payment of corresponding sums to Terremark by the Owner of the
job for which Terremark is General Contractor.

         3.4 On or before the 20"' day of each month the Subcontractor shall
submit to Terremark, in the form required by Terremark, a written requisition

charges for material or service furnished by Terremark to the Subcontractor. The

Architect, shall be due the Subcontractor on or about the 30th day of the
succeeding month (Payment is predicated upon receipt of payment from Owner).

         The Contractor shall keep full and detailed accounts and exercise such
controls as may be necessary for proper financial management under this
Contract, and the accounting and control systems shall be satisfactory to the
Owner. The Owner and the Owners' accountants shall be afforded access to, and
shall be permitted to audit and copy, the Contractor's records, books,
correspondence, instructions, drawings, receipts, subcontracts, purchase orders,
vouchers, memoranda and other data relating to this Contract, and the Contractor
shall preserve these for a period of one (1) year after final payment, or for
such lancer period as may be required by law.

         With each Application for Payment, the contractor shall submit
payrolls, petty cash accounts, receipted invoices or invoices with check
vouchers attached, and any other evidence required by the owner or Architect to
demonstrate that cash disbursements already made by the contractor on account of
the cost of the Work equal or exceed (1) progress payments already received b
the Contractor less that portion of those payments attributable to the
Contractor's fee.

                                       3
<PAGE>
         Each Application for Payment shall be based on the most recent schedule
of values submitted by the Contractor in accordance with the Contract Documents.
The schedule of values shall allocate the entire Guaranteed Maximum Price among
the various portions of the Work, except that the Con tractor's Fee shall be
shown as a single separate item. The schedule of values shall be prepared in
such form and supported by such data to substantiate its accuracy as the Owner
may require. This schedule, unless objected to by the Owner, shall be used as a
basis for reviewing the Contractor's Applications for Payment.

         Applications for Payment shall show the percentage of completion of
each portion of the Work as of the end of the period covered by the Application
for Payment. The percentage of completion shall be the lesser off!) the
percentage of that portion of the Work which has actually been completed, or (2)
the percentage obtained by dividing (a) the expense that has actually been
incurred by the Contractor on account of that portion of the Work for which the
Contractor has made or intends to make actual payment prior to the next
Application for Payment by (b) the share of the Guaranteed Maximum Price
allocated to that portion of the Work in the schedule of Values.

         3.5 No payment will be processed until all required submittals have
been made by subcontractor and accepted by owner or architect.

         3.6 Terremark reserves the right to advance the dates of any payment
(including the final payment) under this Contract if, in its sole judgment, it
becomes desirable to do so.

         3.7 Subcontractor shall furnish, along with last progress draw request,
all necessary warranties, product data, manuals, as-built drawings, and other
closeout documents as required in the specifications.

         3.8 The final payment shall be made after the completion of the Work
covered by this Contract and acceptance thereof by Terremark and the Architect,
provided all Plans and Specifications have been returned to Terremark by the
Subcontractor and also provided the Subcontractor has given to Terremark

THE CONTRACTOR MAY NOT ASSIGN ITS RIGHTS UNDER THIS CONTRACT

1.       CHANGE ORDERS.

         (a)      No changes in the Work shall be made by the Contractor except
                  pursuant to written change order. With each request for a
                  change order, the Contractor will submit worksheets and
                  detailed breakdowns showing the number of units and unit
                  costs. Change orders will not result in additional time or an
                  extension of time unless (i) the change order specifies the
                  amount of the extension of time with detailed backup and (ii)
                  the change order affects the construction schedule and: (iii)
                  the Owner accepts the request for Change Order in writing.

         (b)      Any claims for "extra work" performed by the Contractor must
                  be evidenced by prior written approval from the Owner and the
                  Architect. The Owner shall not be responsible for the payment
                  of any "extra work" performed by the Contractor where said
                  prior written approval has not been obtained or in the event
                  said additional work is requested by the respective tenants of
                  the site under construction. Any additional work to be
                  performed at the request of the tenants will require the
                  approval of the Owner and shall be treated either as a Change
                  Order or, with the Owner's approval, by separate agreement
                  with the tenant.

2.       All testing services required by the Work or in the Bid Documents shall
         be by the Owner. Contractor shall be responsible for coordination,
         ordering, and timing of required testing services. Contractor shall be
         responsible for the cost of any additional tests or re-testing
         resulting from mistakes or deficiencies in the Contractor's Work.

3.       OWNER'S REPRESENTATIVES. One or more representatives of the Owner shall
         be allowed but not required to be on the site at all times, although
         this shall not release the Contractor of any of its responsibilities.

4.       OVERTIME WORK. If, in order to expedite completion on the Work, the
         Owner, for reasons other than default by the Contractor, requires the
         Contractor to work overtime, the Contractor agrees to work such
         overtime and the Owner shall pay the Contractor therefore only the
         Contractor's extra labor cost over the rate for regular time during the
         period of such overtime, including additional insurance and taxes
         incurred by the Contractor with respect thereto plus the Contractor's
         fee and lost efficiency costs if overtime becomes continual. Time slips
         covering such overtime must be submitted to the Owner for approval.
         However, if the Contractor has delayed the progress of the Work, as
         evidenced by a failure to comply with the critical path schedule agreed
         to by the parties, then the Contractor, if requested by the Owner or
         the Architect, shall employ such overtime labor as shall insure that
         the Work will be completed in accordance with Contract Article 3 and as
         may be necessary to keep abreast of the general progress of such other
         job site work, and in either such event the cost of such overtime shall
         be done entirely by the Contractor and there shall be no Contractor fee
         associated therewith.

         in favor of the Contractor shall be assigned to the Owner on or before
         completion of the Work. The Work shall not be considered complete

         cost of the Work to be completed, as reasonably assessed by the
