Subcontractor has caused no delay to Terremark.

                           on the specific day that the current progress
                           schedule dictates, or

                  2.       If Subcontractor, in Terremark's opinion, falls
                           behind in the schedule due to, lack of competent
                           personnel, lack of materials, lack of, subcontractor
                           cooperation, etc.

         2.6 Terremark may immediately assess liquidated damages and withhold
same from subcontractor monthly draw. If liquidated damages are assessed by

have the right to assess subcontractor for the liquidated damages assessed
against it by Owner. If no liquidated damages are assessed, all monies withheld
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
overtime, and provided that the Subcontractor is not in default in any of the
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

Subcontractor shall at its own cost and expense, work such overtime as may be
necessary to avoid delay in the completion of the building.
