               Item 5.        Other Events

          On August 27, 1997,  MasTec,  Inc. announced that the Macri Group, one
     of the largest  commercial  groups in Argentina,  had agreed to be MasTec's
     new 50% partner in Sintelar, S.A., MasTec's Argentinean  telecommunications
     construction subsidiary.  Iecsa S.A., a subsidiary of SOCMA-Sociedad Macri,
     will   acquire   the  50%   interest   for   cash  and   Iecsa's   existing
     telecommunications  infrastructure  business,  which  will be  merged  into
     Sintelar.  The agreement  between  MasTec and the Macri Group also provides
     that the two  companies  will pursue  additional  opportunities  throughout
     South America.

          On  September  3,  1997,  MasTec,  Inc.  announced  that  its  Spanish
     subsidiary,  Sintel,  S.A., had petitioned the Spanish labor authorities to
     approve a restructuring of Sintel's work force. The proposed  restructuring
     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  Sintel   non-union
     affiliates.  The  petition  only  involves  union  workers  principally  in
     Sintel's  outside plant  division  servicing  Telefonica  de Espana,  which
     workers  currently  account for less than fifty percent of that  division's
     revenue.

          On  September 8, 1997,  MasTec,  Inc.  announced  that it had acquired
     AIDCO, Inc. a company engaged in the installation and maintenance of voice,
     date and video local-area networks. AIDCO operates primarily in the Western
     and  Midwestern  states  and is one of two  master  resellers  of  Sumitomo
     Electric  Lightwave  FutureFlex  air-blown  fiber  optic  cabling  systems,
     providing  technical  support and product  delivery  throughout  the United
     States, Canada, and Mexico.

          The Company has issued press releases announcing the foregoing events,
     copies of which are attached as exhibit 99.1 and is incorporated  herein by
     reference.
