MIAMI,  FL - MasTec,  Inc.  (NYSE:  MTZ)  announced  today that it has sold $200
million  in senior  subordinated  notes due in 2008 with a coupon  rate of 7 3/4
percent.  The notes  have been  sold at a  discount  to yield  7.77  percent  to
investors.  The offering was  increased  from $150 million to take  advantage of

purposes, including acquisitions,  working capital and capital expenditures. The
notes were sold in a private placement with registration rights.

with the reception of the investment  community to our note offering,  which has
galvanized  us to continue our growth  strategy.  Our position as the  principal
consolidator  in a fragmented  industry,  coupled with strong access to capital,
provides  us  with  a  unique  opportunity  for  expansion  and  enhancement  of
shareholder value."
