HOUSTON – JULY 11, 2000 – Crown Castle International Corp. (NASDAQ:TWRS) announced today that it has filed a “universal shelf” registration statement on SEC Form S-3 with the Securities and Exchange Commission for up to $1,133.2 million of Common Stock, Preferred Stock, Warrants, Senior Debt and Subordinated Debt.

“Our recent capital market activities, including the issuance of $500 million in senior notes as well as the sale of Crown Castle shares by France Telecom, reduced the capacity under our previously filed shelf registration statements to less than $400 million,” stated Ben Moreland, Crown Castle’s chief financial officer. “Our decision to file this universal shelf brings our total shelf capacity to $1.5 billion, and will provide Crown Castle with greater financial flexibility in the future.”

These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. Any securities offered pursuant to this universal shelf registration statement will only be offered pursuant to a prospectus supplement meeting the requirements of the Securities Act of 1933. This press release shall not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful.
