     MIAMI, FL - MasTec, Inc. (NYSE: MTZ) announced today that Henry ("Hank") N.
Adorno has been hired as the  Company's  Executive  Vice  President  and Special

&  Zeder,  rapidly  expanding  to  become a full  service  law  firm  with  over
seventy-five attorneys in Miami and Ft. Lauderdale.

     MasTec also  announced the  appointment  of Juan Antonio  Casanova as Chief
Executive of Sintel, the Company's Spanish  subsidiary.  Mr. Casanova joined the
Company this past November and has been leading the negotiations for a new labor
agreement with Sintel's  workforce.  Prior to joining the Company,  Mr. Casanova
was  a  senior  executive  with  Entrecanales  Tavora,  S.A.,  a  major  Spanish
construction,   industrial  and  service  conglomerate.  Mr.  Casanova  will  be
responsible  for  implementing  the  Company's  restructuring  plan for  Sintel,
including a reduction in workforce and the further streamlining of operating and
management  procedures,  and will implement strategic  marketing  initiatives to
expand  Sintel's  customer  base and  capitalize on recent  developments  in the
telecommunications and cable television industries.

     In addition,  the Company has announced that Ubiratan Rezende,  Senior Vice
President of International  Operations,  will be relocating to Sao Paulo, Brazil

Rezende will also  continue to oversee the  activities of MasTec  Inepar,  S.A.,

telecommunications construction market in the world over the next several years.
Jorge Mas, President and Chief Executive  Officer,  said: "We at MasTec are very
excited about the quality of management we continue to be able to attract to the
Company.  Hank  Adorno  has  been a  trusted  advisor  to  the  Mas  family  and
subsequently to MasTec for many years. His strong  administrative skills will be
a  welcome  addition  as  the  Company  continues  to  meet  the  challenges  of
exponential  growth.  The further  strengthening  of our  Spanish and  Brazilian
management  teams is well  timed to  allow  the  Company  to  capitalize  on the
tremendous  opportunities  available both in Spain and throughout Latin America.
We welcome  Hank and Juan Antonio to the team and would like to extend a special
thanks to Dr. Rezende for helping establish our current Brazilian  operation and
now  agreeing to  spearhead  further  development  in the  attractive  Brazilian
market."
