HOUSTON, May 31, 2005 /PRNewswire-FirstCall via COMTEX/ -- Crown Castle International Corp. (NYSE: CCI) announced today that it has determined the consideration to be paid in connection with its cash tender offers and consent solicitations relating to its outstanding 10 3/4% Senior Notes due 2011 (CUSIP No. 228227AJ3) (the "10 3/4% Notes"), 9 3/8% Senior Notes due 2011 (CUSIP No. 228227AS3) (the "9 3/8% Notes"), 7.5% Senior Notes due 2013 (CUSIP No. 228227AW4) (the "7.5% Notes") and 7.5% Series B Senior Notes due 2013 (CUSIP No. 228227AY0) (the "7.5% Series B Notes" and, together with the 10 3/4% Notes, 9 3/8% Notes and 7.5% Notes, the "Notes"). The tender offers and consent solicitations are subject to the terms and conditions set forth in the Company's Offer to Purchase and Consent Solicitation Statement dated May 17, 2005.

Holders of Notes who have properly tendered on or prior to 5:00 p.m. (EDT) on May 31, 2005 (such time and date, the "Consent Date") will receive the applicable tender offer consideration described below, a consent payment of $40.00 per $1,000 principal amount of Notes tendered and any accrued and unpaid interest to (but not including) the Initial Optional Early Payment Date (as defined below), which the Company currently expects will occur on or about June 8, 2005. Holders of Notes who properly tender after the Consent Date and prior to midnight (EDT) on June 14, 2005 (the "Expiration Date") will receive the applicable tender offer consideration described below and any accrued and unpaid interest to (but not including) the date on which payment is made for the Notes so tendered.

The consideration for each $1,000 principal amount of Notes tendered was determined today, the eleventh business day before the Expiration Date (the "Price Determination Date"). At any time after the Consent Date and prior to the Expiration Date (such time, the "Initial Optional Early Acceptance Date"), Crown Castle may elect to accept for payment all Notes of a series tendered on or prior to such Initial Optional Early Acceptance Date. Payment for all Notes so accepted will be made promptly thereafter (the "Initial Optional Early Payment Date"). Concurrent with an Initial Optional Early Acceptance Date, Crown Castle will waive all conditions to the tender offer applicable to the series of Notes so accepted and Notes of such series tendered after the Initial Optional Early Acceptance Date and before the Expiration Date will be accepted for payment on each business day during such period for prompt settlement.

The tender offer consideration for each series of Notes tendered and accepted for payment is as follows: $1,024.22 for each $1,000 principal amount of 10 3/4% Notes; $1,064.80 for each $1,000 principal amount of 9 3/8% Notes; $1,098.56 for each $1,000 principal amount of 7.5% Notes; and $1,098.56 for each $1,000 principal amount of 7.5% Series B Notes. The tender offer consideration for each $1,000 principal amount of Notes of a series tendered is an amount equal to (i) the sum of the present values as of June 8, 2005, of (A) the redemption price applicable to such series of Notes (as set forth in the table below) on the earliest date on which Notes of such series may be redeemed (as set forth in the table below) and (B) the interest that would accrue on the applicable series of Notes so tendered from (but not including) the most recent payment of interest up to (but not including) the earliest redemption date, in each case determined on the basis of a yield from June 8, 2005 to the earliest redemption date equal to the sum of (x) the yield to maturity on the reference security applicable to such series of Notes (as set forth in the table below) as of the Price Determination Date, and (y) 50 basis points, minus (ii) interest from the most recent payment of interest preceding the Initial Optional Early Payment Date to (but not including) such date, minus (iii) a consent payment of $40.00.
