Item 2.  Acquisition or Disposition of Assets.

      On November 16, 1998,  American Tower Corporation (the "Company" or "ATC")
entered into an Agreement and Plan of Merger ("the Omni Merger  Agreement") with
OmniAmerica, Inc., a Delaware corporation ("Omni"), and American Towers, Inc., a
wholly owned subsidiary of ATC and a Delaware corporation  ("ATI"),  pursuant to
which Omni will merge with and into ATI, which will be the surviving corporation
(the   "Omni   Merger").    Omni   owns,    manages   and   develops   multi-use
telecommunications  sites  for  radio  and  television   broadcasting,   paging,
cellular,  PCS and other wireless  technologies and offers nationwide,  turn-key
tower construction and installation services through its Specialty  Constructors
subsidiary.   Omni  currently  owns  246  towers  (giving  effect  to  announced
transactions) and is currently  developing or has agreed to build  approximately
470 more sites for  specific  tenants.  Pursuant to the Omni  Merger  Agreement,
which has been  approved  by the  Board of  Directors  of ATC and  Omni,  and by
holders of shares representing the required majority of the voting power of Omni
Common Stock,  Omni  stockholders  will receive 1.1 shares of ATC Class A Common
Stock  for each  share of  Common  Stock of  Omni.  In the  aggregate,  ATC will
exchange  approximately  17.7  million  shares  of ATC  Class A Common  Stock in
exchange for the approximately 16.1 million fully-diluted shares of Common Stock
of Omni,  plus  the  assumption  of debt.  Consummation  of the Omni  Merger  is
expected to occur in the first  quarter of 1999,  subject to certain  conditions
including,  the expiration or early  termination of the waiting period under the
Hart-Scott-Rodino  Antitrust  Improvements  act of 1976,  as  amended  (the "HSR
Act"). Upon the consummation of the Omni Merger,  Jack D. Furst, the Chairman of
Omni and a partner of Hicks,  Muse,  Tate & Furst  Incorporated,  Omni's largest
stockholder, will be elected to the Board of Directors of ATC.

      On November  16, 1998,  ATC entered  into an Agreement  and Plan of Merger
(the "TeleCom Merger Agreement") with TeleCom Towers, L.L.C., a Delaware limited
liability  company  ("TeleCom"),  and ATI,  pursuant to which TeleCom will merge
with and  into  ATI,  which  will be the  surviving  corporation  (the  "TeleCom
Merger"). TeleCom owns, or co-owns, approximately 367 towers and manages another
130  revenue-generating  sites in 27  states.  Pursuant  to the  TeleCom  Merger
Agreement,  which has been approved by Board of Directors of ATC, the Management
Committee  of TeleCom,  and by holders of  interests  representing  the required
majority of the voting power of TeleCom interests, ATC will pay a purchase price
for TeleCom of approximately  $155.0 million,  subject to adjustment for closing
date  working  capital.  ATC will assume  approximately  $30.0  million of debt,
subject to adjustment for interim  acquisitions  and capital  expenditures.  The
purchase price (except for the working capital  adjustment,  which is payable in
cash)  will be paid 60% in ATC  Class A Common  Stock  (based on  average  stock
prices ten days before and ten days after  November  16,  1998) and 40% in cash.
Consummation  of the TeleCom Merger is  conditioned  on, the expiration or early
termination  of the waiting  period under the HSR Act, and  accordingly,  is not
expected to take place until the first quarter of 1999. Upon the consummation of
the TeleCom Merger,  Dean H. Eisner,  Vice President,  Business  Development and
Planning of Cox Enterprises,  Inc., will be elected to the Board of Directors of
ATC.
