Crown Castle International Announces Potential Notes Offering by Certain
Subsidiaries

HOUSTON, Dec. 5, 2012 (GLOBE NEWSWIRE) -- Crown Castle International Corp.
(NYSE:CCI) announced today that its subsidiary, CC Holdings GS V LLC, is
contemplating an offering, in a private transaction, of senior notes
("Notes"), subject to market conditions. CC Holdings GS V LLC, through its
subsidiaries, holds a majority of the U.S. towers originally acquired by Crown
Castle in its 2007 acquisition of Global Signal, Inc. Crown Castle currently
expects that any such Notes offering would commence and close prior to the end
of 2012.

The net proceeds of any such offering would be used to redeem or repurchase CC
Holdings GS V LLC's existing senior notes. The size and terms of any such
offering, and the actual use of proceeds, are subject to market conditions at
the time of commencement of any such offering.

This press release is not an offer to sell or the solicitation of an offer to
buy, nor shall there be any sale of the Notes in any jurisdiction in which any
such offer, solicitation or sale would be unlawful prior to the registration
or qualification under the securities laws of any such jurisdiction. The
Notes, if offered, will be offered to qualified institutional buyers under
Rule 144A and to persons outside of the United States under Regulation S. The
Notes will not be registered under the Securities Act of 1993, as amended (the
"Securities Act"), or any state securities laws, and, unless so registered,
may not be offered or sold in the United States except pursuant to an
exemption from the registration requirements of the Securities Act and
applicable state securities laws.
