                    UNION RESPONSE TO MASTEC'S LABOR PETITION

MIAMI,  FL - MasTec,  Inc.  (NYSE:  MTZ)  announced  today that the labor unions
representing the workers of Sintel, S.A., the company's Spanish subsidiary, have
announced  work  stoppages at Sintel in response to Sintel's  application to the
Spanish labor  authorities to restructure  Sintel's work force.  The unions have
announced  that  workers  will not work  two  half  days per week  until a labor
agreement is reached.  The Company expects Spanish labor  authorities to respond
to the application in mid to late October.

Jorge Mas, President and Chief Executive Officer of MasTec, said: "The temporary
disruption  at Sintel is a  necessary  and  expected  part of the process in our
attempt to reduce  Sintel's  cost  structure  for outside  plant  services.  Our
objective is to correct the  imbalanced  cost  structure at Sintel and bring the
outside plant labor  productivity in line with that experienced  through the use
of independent contractors."

Independent  contractors  currently  account for  approximately  55% of Sintel's
outside plant services  revenue.  On September 3, the Company  announced that it
had filed a petition with Spanish labor  authorities to approve a  restructuring
of Sintel's  work force which would  result in  approximately  1,400 of Sintel's
workers  being  removed from payroll and  approximately  1,200 being  rehired at
lower cost either as independent  contractors or as employees of other non-union
affiliates.

Opening the Lines of  Communication(R)  worldwide,  MasTec is one of the world's
leading telecommunications and related infrastructure service providers, serving
clients throughout the United States, Latin America and Spain.
