Item 5. Other Events

    On March 15, 1999, Crown Castle International Corp. ("CCIC" or the 
"Company") announced that its U.K. operating subsidiary, Castle Transmission 
International ("CTI") entered into an agreement with One2One, pursuant to which 
CTI has agreed to manage, develop and, at its option, acquire up to 821 towers
(the "Proposed One2One Transaction"). These towers represent substantially all 
the towers in One2One's 1,800 MHz nationwide wireless network in the United 
Kingdom. Approximately one-half of these 821 towers can accommodate additional
tenants. CTI expects to upgrade or replace the other towers as demand for space 
on such towers arises. CTI believes that the cost of upgrading or replacing any 
single tower will not exceed $40,000.
        
    CTI will be responsible for managing and leasing available space on the 
towers, and will receive all the income from any such third party leases. The 
term of the management arrangements will be up to 25 years. During the 
three-year period following the closing, CTI will have the right, at its option,
to acquire for (Pounds)1.00 per site One2One's interest in the 821 towers, to 
the extent such interests can be assigned. One2One has also agreed to include 
any new One2One towers constructed during the term of the agreement.

    On March 16, 1999, CCIC announced that CCIC and CCP Inc. ("CCP"), its wholly
owned indirect subsidiary, entered into an agreement with Powertel, Inc. and
five of its subsidiaries (collectively, "Powertel") pursuant to which the
parties agreed that the Company would purchase from Powertel approximately 650
towers and related assets and liabilities (the "Proposed Powertel Acquisition").

    The Company will pay to Powertel aggregate consideration of $275.0 million
("the Purchase Price"), (subject to adjustment based on the amount of towers
actually tendered to us at closing) for the 650 towers. At closing, Powertel
will pay the Company a credit against the purchase price in an aggregate amount
of $383,000.00 ("the Purchase Price Credit"), as consideration for its
acceptance of certain towers containing site leases which may require revenue
received from Powertel or its affiliates to be shared with the site lessors. The
Purchase Price less the Purchase Price Credit is referred to as the "Closing 
Price". Pursuant to the Asset Purchase Agreement, the Company has placed $50.0
million in escrow to be applied to the Closing Price. In the event that Powertel
has fulfilled all conditions precedent to closing and the Company is unable
or unwilling to deliver the balance of the Closing Price, Powertel will receive
up to the full $50.0 million as liquidated damages. 
 
    Pursuant to the Asset Purchase Agreement, at closing Powertel will assign
and the Company will assume five master site agreements ("the Master Site
Agreements"), pursuant to which Powertel will agree to pay the Company monthly
rent of $1,800 per tower for continued use of space Powertel or its affiliates
occupies on the towers. This per tower amount is subject to increase on each
fifth anniversary of the agreement and as Powertel adds equipment to these
towers.

    The operative agreements governing both the Proposed One2One Transaction and
the Proposed Powertel Acquisition are subject to a number of significant 
conditions. There can be no assurance that either transaction will be 
consummated on the terms described herein or at all.
 
    The following descriptions of the agreements related to the Proposed
Powertel Acquisition are summaries of the material portions of those agreements
or summaries of the terms of the agreements as currently contemplated. These
descriptions are qualified in their entirety by reference to the complete text
of the agreements. 
 
Asset Purchase Agreement
 
    Purchase Price. Pursuant to the Asset Purchase Agreement, the Company will
pay the Closing Price in cash on or before June 4, 1999 ("the Closing Date"),
to Powertel for Powertel's tower structures, rights to tower sites, related
assets and rights under applicable governmental permits. The purchase price is
subject to adjustment up or down based on the actual number of sites tendered at
closing. The Asset Purchase Agreement provides that sites considered defective
or incomplete ("Rejected Sites"), will not be tendered at closing, and
consequently, the purchase price will be reduced by an amount equal to $423,077
for each Rejected Site.
 
    Terms and Conditions. In connection with the Proposed Powertel Acquisition,
the Company and Powertel are making certain representations and warranties which
must be true on the Closing Date in order for the transaction to be consummated.
Other conditions which must be satisfied on the Closing Date include:
 
  .  compliance by the Company and Powertel with the Asset Purchase Agreement;
 
  .  absence of litigation;
 
  .  receipt of regulatory approvals; and
 
  .  absence of any material adverse effect with respect to the Powertel
     assets and assumed liabilities.
 
    In addition, pursuant to the Asset Purchase Agreement, the Company has
deposited $50.0 million in cash ("the Escrow Deposit"), with SunTrust Bank
Atlanta ("the Escrow Agent"). At closing, the Escrow Deposit will be delivered
to Powertel and credited against the Closing Price. However, the Company has
agreed that the Escrow Deposit will be forfeited to Powertel in the event that
the Company is unable to receive adequate financing to consummate the
acquisition and thus is unable to close the acquisition in a timely manner. As a
condition to the Asset Purchase Agreement, the Company has agreed to use its
reasonable best efforts to have a registration statement relating to such
financing declared effective as expeditiously as possible. Further, upon the
occurrence of certain events, the Company is required to provide Powertel with
adequate written assurance that it has at least one alternative financing
source, which in Powertel's sole judgment provides it assurance that the Company
will have on hand a minimum of an additional $225.0 million in cash to apply to
the Purchase Price at closing (a "Financing Assurance"). Such Financing
Assurance must be received by Powertel within five days of the occurrence of
certain events including:
 
  .  the Company's failure to file the registration statement before March 19,
     1999;

   . the withdrawal or abandonment of the registration statement or the
     decision not to proceed with the offerings contemplated by the registration
     statement;
 
  .  the Company's failure to commence presentations to institutional investors
     by May 15, 1999 or, after commencement of such presentations, termination
     or abandonment of such presentations and failure to proceed to pricing of
     the offerings.
 
    In the event the Company is required to provide Powertel with a Financing
Assurance, Powertel will have five days to accept or reject it. If Powertel
rejects the Financing Assurance, the Company will have ten days from receipt of
the rejection to deliver the $225.0 million balance of the Closing Price to the
Escrow Agent, who will deliver the entire Closing Price to Powertel at closing.
However, if the Company is unable or unwilling to deliver the additional sum
into escrow, Powertel will have the right to unilaterally terminate the Asset
Purchase Agreement, and receive, as its sole remedy, from the Escrow Deposit
liquidated damages in the amount of $10.0 million on or prior to May 15, 1999 or
$25.0 million after May 15, 1999 but prior to June 4, 1999. If on June 4, 1999,
Powertel has fulfilled all of its obligations and conditions precedent to
closing in all material respects and has not defaulted or breached its
obligations under the Asset Purchase Agreement, and the Company has failed to
deliver the additional sum into escrow or is otherwise unable or unwilling to
deliver the Purchase Price, Powertel will receive as liquidated damages the
entire amount of the Escrow Deposit.
 
Master Site Agreement
 
    On the Closing Date, the parties to the Asset Purchase Agreement and certain
of Powertel's affiliates will enter into Master Site Agreements governing all
towers acquired pursuant to the Asset Purchase Agreement. Pursuant to the Master
Site Agreements, Powertel or certain affiliates will agree to continue to lease
the space it currently occupies on the towers to be acquired by the Company. The
monthly rent paid by Powertel for each tower will be $1,800. Such monthly
payment is subject to increase based on an agreed upon schedule if and when
Powertel adds equipment to a site. Nonetheless, the monthly rent, including
additional rents related to the addition of certain equipment, shall be
increased on each fifth anniversary of the agreement up to an amount that is
115% of the rent paid during the preceding five year period. The Master Site
Agreements provide that space not occupied by Powertel on the acquired towers
can be leased to third parties at the Company's sole option.
 
    Pursuant to the Master Site Agreements, the term of each tower lease will be
ten years. Powertel has the right to extend any site lease for up to three
additional five year periods. Each site lease will automatically renew for an
option term unless Powertel notifies the Company of its intent not to renew at
least 180 days prior to the end of the then current term.
