Client: Crown Castle International Corp. Contacts: W. Benjamin Moreland, CFO Jay Brown, VP Finance Crown Castle International 713-570-3000 FOR IMMEDIATE RELEASE Ken Dennard / kdennard@easterly.com Lisa Elliott / lisae@easterly.com Easterly Investor Relations 713-529-6600 CROWN CASTLE UPDATES POTENTIAL IMPACT OF ITV DIGITAL LIQUIDATION Expedited Re-issuance of Digital Terrestrial Television Licenses Expected HOUSTON - MAY 1, 2002 - Crown Castle International Corp. (NYSE: CCI) announced today further details regarding the potential impact on its UK subsidiary, Crown Castle UK Limited (CCUK), of liquidation plans of ITV Digital (ITV). As discussed in Crown Castle's 2001 Form 10-K and widely reported in the press, ITV filed for administration on March 27, 2002, the UK equivalent of Chapter 11 bankruptcy. After unsuccessful efforts by the administrator to sell the ITV business as a going concern, ITV has announced plans to liquidate its assets. ITV provided a digital terrestrial television (DTT) service on a subscription basis to approximately 1.2 million subscribers in the UK. Since 1999, CCUK has been responsible for the transmission of the ITV signal through the CCUK-owned DTT network. The DTT licenses previously owned by ITV are being re-issued by the UK Independent Television Commission on an expedited basis. CCUK is currently in discussions to offer transmission services over its network to prospective broadcasters interested in obtaining the DTT licenses. With the ITV liquidation and suspension of service, further on-going collections under the ITV transmission contract are not expected. Additionally, recovery of amounts due CCUK under the contract as a creditor in the administration process are also uncertain. CCUK had gross revenues of approximately $27.6 million annually under the transmission contact. If current efforts to re-market the CCUK network prove unsuccessful, CCUK expects EBITDA to be impacted negatively by approximately $16 million in 2002 and approximately $23 million annually assuming no significant mitigation of costs. ITV represented approximately 10 percent of the 2001 gross revenue of CCUK and approximately 3 percent of the 2001 gross revenue of Crown Castle. As a result, Crown Castle has lowered 2002 site rental and transmission revenues by $28 million to between $657 and $682 million, 2002 tower gross profit by $16 million to between $389 and $434 million and 2002 total EBITDA by $16 million to between $369 and $399 million. No further adjustments have been made to Crown Castle's 2002-2004 previously

announced projections. The ITV liquidation will require CCUK to seek a waiver or amendment of certain covenants under its (pound)150 million revolving loan agreement. John P. Kelly, President and Chief Executive Officer, stated, "While we are obviously disappointed with this loss of revenue and EBITDA, we are encouraged by the discussions underway with prospective new licensees. We are also optimistic that agreements can be reached with new licensees in our effort to replace the revenue and EBITDA previously generated under the ITV contract. This will have no impact on our ability to successfully execute our obligations under our other broadcast contracts, most notably our agreements with the BBC." Additionally, Crown Castle confirmed that the ITV liquidation has no impact on its US credit lines and as of March 31, 2002, Crown Castle had approximately $940 million in cash and marketable securities and full access to the undrawn amounts on its US credit facilities of approximately $545 million, providing the Company with approximately $1.49 billion in liquidity.
