                 LAMAR ADVERTISING COMPANY ANNOUNCES ISSUANCE OF
       DOJ CONSENT DECREE REGARDING CLEAR CHANNEL AND AMFM DIVESTITURE OF
                           LAMAR CLASS A COMMON STOCK




Baton Rouge, LA -- August 30, 2000, Lamar Advertising Company (Nasdaq: LAMR), a
leading owner and operator of outdoor advertising and logo sign displays, today
announced that pursuant to a consent decree filed by the Department of Justice,
26,227,273 shares of Lamar Advertising Company Class A common stock currently
held by AMFM Operating Inc., an indirect wholly owned subsidiary of AMFM Inc.,
will be subject to required divestiture before January 1, 2003 as a condition to
DOJ's approval of the merger of AMFM Inc. and Clear Channel Communications, Inc.

Lamar has amended the shareholder agreement and registration rights agreement
previously entered into with AMFM in connection with Lamar's purchase of AMFM's
outdoor advertising business on September 15, 1999, which were effective upon
the consummation of the merger of AMFM and Clear Channel, in accordance with the
consent decree.

Under the amended agreements, Lamar is required to register for sale the
26,227,273 shares of Class A common stock formerly held by AMFM. Further, AMFM
and Clear Channel are divested of the right to board representation and approval
rights over certain major transactions by Lamar. In addition, they have agreed
to vote their shares in the same proportion as the vote of all holders of Lamar
voting stock.

The consent decree prohibits AMFM and Clear Channel from exercising any
governance rights over Lamar. The consent decree also prohibits AMFM and Clear
Channel from acquiring any additional shares of Lamar except in connection with
an acquisition of a majority voting interest in the company, which would be
subject to the requirements of the Hart-Scott-Rodino Antitrust Improvements Act.
The consent degree requires that AMFM's board representatives, Thomas O. Hicks
and R. Steven Hicks, resign from Lamar's board of directors and all committees
of the board.

Lamar Advertising Company is a leading outdoor advertising company currently
operating 149 outdoor advertising companies in 42 states, logo franchises in 20
states and the province of Ontario, Canada and 31 transit advertising franchises
in nine states. CONTACT: Keith A. Istre, Chief Financial Officer
