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.

                AMERICAN TOWER CORPORATION AND OMNIAMERICA, INC.
                                    TO MERGE

Boston, Massachusetts and Albuquerque, New Mexico - November 16, 1998 - American
Tower  Corporation  (NYSE:  AMT) and  OmniAmerica,  Inc.  (NASDAQ:  XMIT)  today
announced  that they have  entered  into a  definitive  agreement  to merge in a
stock-for-stock transaction.

Under  the terms of the  agreement,  which has been  approved  by the  boards of
directors of both companies, OmniAmerica shareholders will receive 1.1 shares of
American  Tower  Class  A  Common  Stock  for  each  OmniAmerica  share.  In the
aggregate, American Tower will exchange approximately 17.7 million shares of its
stock for the  approximately  16.1  million  fully  diluted  OmniAmerica  shares
outstanding, plus it will assume OmniAmerica's debt.

The combined  American  Tower/OmniAmerica  will be a leader in the  fast-growing
tower  industry  with a  national  portfolio  of tower  assets  and  significant
capabilities in the areas of site  acquisition,  construction  and  development,
leasing,  and operations  management.  The company will have approximately 3,044
towers under  ownership or  management,  with another 840 in the  development or
construction  stages (giving  effect to this  transaction  and American  Tower's
acquisition of TeleCom Towers, which was also announced today).

Steve Dodge,  Chairman of American Tower, said of the merger,  "Once Carl Hirsch
and I began a dialogue,  the merits of this merger  quickly  became  apparent to
both of us.  Our  company's  site  acquisition  and  zoning  skills  will now be
combined with  OmniAmerica's  unparalleled  construction  skills. We have strong
tower development momentum in the East,  OmniAmerica in the West. Both companies
have a commitment  to tall towers,  and both have strong  balance  sheets.  Most
importantly,  this merger  positions  American  Tower to provide a more complete
range of services to its  customers.  We look  forward to working  with the fine
people at OmniAmerica  and to our  association  with Carl and with Hicks,  Muse,
Tate & Furst."

Carl E. Hirsch,  President and Chief  Executive  Officer of  OmniAmerica,  said,
"Throughout  OmniAmerica's  existence, our primary objective has been to deliver
value to our  shareholders  and our  customers.  By joining forces with American
Tower, we are taking a significant step towards achieving that goal. OmniAmerica
has built a dedicated

                                   (continued)




team of  experienced  professionals  whose  skill sets  complement  those of the
outstanding  American  Tower  team.  It is an honor to work with Steve Dodge and
that team as we seek to position the  combined  company to serve the tower needs
of its nationwide client base of wireless carriers and broadcasters."

Completion of the  transaction,  which is expected to occur in the first quarter
of 1999, is subject to the expiration of the applicable waiting period under the
Hart-Scott-Rodino Act, as well as customary closing conditions.

Once the transaction is completed,  Jack D. Furst, Chairman of OmniAmerica and a
Partner of Hicks, Muse, Tate & Furst,  OmniAmerica's  largest shareholder,  will
join the American Tower Board of Directors.

Credit  Suisse  First  Boston  acted as  financial  advisor  to  American  Tower
Corporation in this transaction, and BT Wolfensohn acted as financial advisor to
OmniAmerica, Inc.

OmniAmerica,  Inc. owns, manages and develops multi-use telecommunications sites
for radio and television broadcasting,  paging, cellular, PCS and other wireless
technologies.   It  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.  The company offers  nationwide,  turn-key
tower construction and installation services through its Specialty  Constructors
subsidiary,  "tall tower"  fabrication  and  construction  through its ownership
interest  in  Kline  Towers,   and  its  Microwave  Tower  Services   subsidiary
manufactures tower-related components.

Boston-based  American  Tower  Corporation  is a leading  independent  owner and
operator of broadcast and wireless communications sites in the United States and
currently  operates in 44 states and the District of  Columbia.  With respect to
the  announcements  today of the  OmniAmerica  and TeleCom Towers  transactions,
Steve Dodge remarked, "Together these mergers create a more vibrant company with
an  improved  asset mix, a denser  national  footprint,  and a greatly  enhanced
ability  to  be  responsive  to  the  needs  of  our  customers.   Further,  the
stock-oriented nature of these transactions preserves the balance sheet strength
of American Tower. We look forward to completing both mergers."
