                          FORWARD-LOOKING STATEMENTS

The document attached hereto as Exhibit 99.1 contains numerous forward-looking
statements, based on management's current beliefs and assumptions. The forward-
looking statements involve expectations, projections and estimates regarding the
wireless industry or Crown Castle International Corp. (including its
subsidiaries), including expectations, projections and estimates regarding: (i)
implementation of our strategy, (ii) future free cash flow targets, (iii) demand
for our towers, (iv) new tenant co-location rates, (iv) future margins, (iv)
financial performance of our towers, (v) EBITDA growth rates, (vi) future
revenues, expenditures and liquidity, (vii) future cell site density, (viii)
emergence of new mobile technologies, including 2.5/3G, and (ix) carrier
subscriber growth rates.

Such forward-looking statements are subject to numerous risks, uncertainties and
assumptions, including (i) those relating to the matters described above, (ii)
those included in the Risk Factors sections of the Company's filings with the
Securities and Exchange Commission, and (iii) the following:

 .  Demand for towers and wireless communication sites may be lower or slower
   than anticipated for numerous reasons, including reduced carrier expansion,
   carrier consolidation, network sharing, technology development, or RF health
   concerns

 .  Demand for wireless communications may be lower or slower than anticipated
   for numerous reasons, including slow customer adoption rates of 2.5/3G and
   other technologies

 .  Our strategy may be more difficult to implement than anticipated due to
   financial or other reasons, including our significant amount of indebtedness,
   or reduced cash flow as a result of reduced revenues or increased operating
   costs, interest rates or capital expenditures

Should one or more of these risks materialize, or should any underlying
assumption prove incorrect, actual results may vary materially from those
projected in the forward-looking statements.  The Company assumes no obligation
to update publicly any forward-looking statements, whether as a result of new
information, future events or otherwise.
