ARRANGEMENT OF A REGISTRANT </B></FONT></P> <P STYLE="margin-top:6px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">On August&nbsp;17, 2006, Crown Castle International Corp. (&#147;Company&#148;) entered into five-year forward-starting
interest rate swap agreements with a combined notional amount of $750 million to hedge the variability of future interest rates in contemplation of the issuance of $750 million of additional Tower Revenue Notes by a subsidiary of the Company, which
is expected to occur on or before January&nbsp;31, 2007. Under the swap agreements, the Company has agreed to pay a fixed interest rate of approximately 5.2%, beginning on or before January&nbsp;31, 2007 through January&nbsp;31, 2012, in exchange
for receiving floating payments based on three-month LIBOR on the same $750 million notional amount for the same five-year period. The swap agreements will be cash settled, in accordance with their terms, on or before January&nbsp;31, 2007.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT FACE="Times New Roman" SIZE="2">As a result of the above described agreements and the swap agreements entered into in June 2006 with a combined notional amount of $250 million, the
Company has entered into forward-starting interest rate swap agreements with a combined notional amount of $1 billion to hedge its exposure to fluctuations in LIBOR in contemplation of the issuance of $1 billion of additional Tower Revenue Notes by
a subsidiary of the Company, which is expected to occur on or before January&nbsp;31, 2007. The Company expects the proceeds of the contemplated Tower Revenue Notes issuance to be used to repay the $1 billion term loan under its 2006 Credit
Facility. </FONT></P> <P STYLE="margin-top:24px;margin-bottom:0px" ALIGN="center"><FONT FACE="Times New Roman" SIZE="2"><B>Cautionary Language Regarding Forward-Looking Statements </B></FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT
