I. INFORMATION ABOUT VOTING

Solicitation of Proxies. The Board of Directors ("Board") of Crown Castle
International Corp. ("CCIC" or the "Company") is soliciting proxies for use at
the 2003 Annual Meeting of CCIC ("Annual Meeting") and any adjournments of the
Annual Meeting. CCIC first sent this proxy statement, the accompanying form of
proxy and the CCIC Annual Report for 2002 to its stockholders on or about April
23, 2003.

Agenda Items.  The agenda for the Annual Meeting is to:

    1. Elect four class II directors for a term of three years;

    2. Ratify the appointment of KPMG LLP as the Company's independent public
       accountants for 2003; and

    3. Conduct other business properly before the Annual Meeting.

Who can Vote. You can vote at the Annual Meeting if you are a holder on the
Record Date of CCIC's common stock, par value of $0.01 per share ("Common
Stock"), or CCIC's 8 1/4% Series A Cumulative Convertible Redeemable Preferred
Stock ("8 1/4% Convertible Preferred Stock"). The record date for determining
the stockholders entitled to notice of, and to vote at, the Annual Meeting is
the close of business on April 9, 2003 (the "Record Date"). Holders of Common
Stock will have one vote for each share of Common Stock, and holders of 8 1/4%
Convertible Preferred Stock, which vote on an as converted basis, will have an
aggregate of 7,441,860 votes. As of the close of business on the Record Date,
there were 223,661,634 shares of Common Stock and 200,000 shares of 8 1/4%
Convertible Preferred Stock outstanding. As of the Record Date, the outstanding
shares of 8 1/4% Convertible Preferred Stock were convertible into an aggregate
of 7,441,860 shares of Common Stock. All outstanding shares of Common Stock are
entitled to vote, other than the 15,597,783 shares of Common Stock held by
Crown Atlantic Holding Company LLC and the 5,063,731 shares of common stock
held by Crown Castle GT Company LLC (the limited liability companies for CCIC's
joint ventures with certain indirect subsidiaries of Verizon Communications,
Inc.), which are not entitled to vote or be counted for quorum purposes while
held by such venture.

How to Vote. You may vote in two ways:

  .   You can come to the Annual Meeting and cast your vote there; or

  .   You can vote by signing and returning the enclosed proxy card (or
      contacting the internet or telephone voting service listed on your proxy
      card). If you do, the individuals named on the card will vote your shares
      in the manner you indicate.

Use of Proxies. Unless you tell the Board on the proxy card to vote
differently, the Board plans to vote all shares represented by the signed and
returned proxies FOR the Board

                                      3



nominees named herein and FOR the ratification of the appointment of KPMG LLP
as the Company's independent public accountants for 2003. The Company does not
now know of any other matters to come before the Annual Meeting. If they do,
proxy holders will vote the shares represented by the proxies in their best
judgment.

Revoking a Proxy. You may revoke your proxy at any time before it is exercised.
You can revoke a proxy by:

  .   Sending a written notice of revocation to the Corporate Secretary of CCIC;

  .   Delivering a properly executed, later-dated proxy; or

  .   Attending the Annual Meeting and voting in person.

The Quorum Requirement. A quorum of stockholders is needed to hold a valid
Annual Meeting. A quorum will exist to hold a valid Annual Meeting if the
holders of at least a majority in voting power of the outstanding shares of
Common Stock and 8 1/4% Convertible Preferred Stock entitled to vote at the
Annual Meeting either attend the Annual Meeting in person or are represented by
proxy. Abstentions and broker non-votes are counted as present for the purpose
of establishing a quorum. A broker non-vote occurs when a broker votes on some
matters on the proxy card but not on others because the broker has not received
voting instructions from its customer or does not have the authority to do so.

Vote Required for Action. Directors are elected (Proposal 1) by a plurality
vote of the holders of shares of Common Stock and the holders of 8 1/4%
Convertible Preferred Stock present in person or represented by proxy at the
Annual Meeting and entitled to vote on the election of directors, voting
together as a single class. The ratification of KPMG LLP as CCIC's independent
public accountants for 2003 (Proposal 2) requires the affirmative vote of the
holders of a majority of the voting power represented by the shares of Common
Stock and 8 1/4% Convertible Preferred Stock present in person or represented
by proxy at the Annual Meeting and entitled to vote on such matter, voting
together as a single class.

Generally, all other actions require the affirmative vote of a majority of the
voting power represented by shares of Common Stock and 8 1/4% Convertible
Preferred Stock present in person or represented by proxy at the Annual Meeting
and entitled to vote on such matters, voting together as a single class. With
respect to Proposal 1, abstentions and broker non-votes have no effect on
determinations of plurality, except to the extent that they affect the total
votes received by any particular candidate. Abstentions have the effect of a no
vote with respect to Proposal 2. Shares represented by broker non-votes will
not be considered to be present at the Annual Meeting for purposes of Proposal
2; therefore, broker non-votes will have the practical effect of reducing the
number of affirmative votes required to achieve a majority vote by reducing the
total number of shares from which the majority is calculated.

                                      4



II. PROPOSALS

1. The Election of Directors

CCIC has three classes of directors of as nearly equal size as possible. The
term for each class is three years. Class terms expire on a rolling basis, so
that one class of directors is elected each year. The term for class II
directors expires at the 2003 Annual Meeting.

The nominees for class II directors this year are: Carl Ferenbach, Ari Q.
Fitzgerald, John P. Kelly and William D. Strittmatter. Mr. Strittmatter is the
nominee of GE Capital pursuant to the terms of CCIC's 8 1/4% Convertible
Preferred Stock.

Each nominee has consented to be nominated and has expressed his intention to
serve if elected. The Board expects that each of the nominees for class II
directors will be able and willing to serve as a director. If any nominee is
not available, the proxies may be voted for another person nominated by the
current Board to fill the vacancy, or the size of the Board may be reduced.
Information about the nominees, the continuing directors and the Board is
contained in the next section of this proxy statement.

The Board of Directors recommends a vote FOR the election of Carl
Ferenbach, Ari Q. Fitzgerald, John P. Kelly and William D. Strittmatter as
class II directors.

                                      5



2. Ratification of Appointment of Independent Public Accountants

The Audit Committee of the Board has appointed KPMG LLP to continue to serve as
CCIC's independent public accountants for 2003. KPMG LLP has served as CCIC's
independent public accountants since 1995. In the event the shareholders do not
ratify the appointment, the appointment will be reconsidered by the Audit
Committee and the Board.

The Company expects a representative of KPMG LLP to attend the Annual Meeting.
The representative will have an opportunity to make a statement if he or she
desires and also will be available to respond to appropriate questions.

Audit Fees. The aggregate fees, including out-of-pocket expenses, billed for
professional services rendered by KPMG LLP for the audit of the Company's
consolidated financial statements as of and for the year ended December 31,
2002, and the reviews of the Company's unaudited condensed consolidated interim
financial statements as of March 31, 2002, June 30, 2002, and September 30,
2002 were $502,000.

Financial Information Systems Design & Implementation Fees. KPMG LLP did not
engage in any activities or receive any fees for 2002 relating to designing or
implementing hardware or software systems that aggregate source data underlying
the financial statements or generate information that is significant to the
Company's financial statements taken as a whole.

All Other Fees. In addition to the fees described above, aggregate fees,
including out-of-pocket expenses, of $1,060,000 were paid to KPMG LLP during
the year ended December 31, 2002, primarily for the following professional
services: statutory and other audits ($499,000); tax-related services
($417,000); and audit-related services ($144,000).

The Board of Directors recommends a vote FOR ratification of the appointment of
KPMG LLP as the Company's independent public accountants for the year 2003.

Board Compensation and Relationships

..   Independence. All members of the Board are independent directors, as
    defined under existing NYSE listing standards, except Mr. Kelly, our
    President and Chief Executive Officer.

..   Compensation Plan. The Board maintains a compensation arrangement for
    independent directors of CCIC. Effective February 20, 2003, as further
    described below, the Board made certain amendments to this compensation
    arrangement.

..   Retainer and Fees. Each independent director of CCIC receives an annual
    retainer of $20,000 ($25,000 for each Board committee chairman) paid
    quarterly and reimbursement of reasonable incidental expenses. Each
    independent director also receives $1,500 for attendance at each Board
    meeting held "in person" and $500 for attendance at each Board meeting held
    by conference call (increased to $1,000 in February 2003). In addition,
    each independent director receives $1,500 for each Board committee meeting
    attended (plus, in the case of a Board Committee Chairman, an additional
    $1,000 for each committee meeting after the fourth such meeting in any
    given year).

                                      15



..   Equity Compensation. Historically, at the first Board meeting of each year,
    CCIC has granted each independent director an option to purchase 15,000
    shares of Common Stock pursuant to the Amended and Restated 1995 Stock
    Option Plan. In addition, each new independent director has been granted an
    option to purchase 25,000 shares of Common Stock upon such director's
    initial election or appointment to the Board. The exercise price of such
    options equals the fair market value of the shares at the close of business
    on the date of grant. The options have a 10-year life and are exercisable
    on the date of grant. For 2002, CCIC granted each of Mr. Hack, Mr.
    Hatfield, Mr. Hogan, Mr. Hutchison, Mr. Martin, Mr. McKenzie and Mr.
    Strittmatter (on behalf of GE Capital) an option to purchase 15,000 shares
    of Common Stock with an exercise price of $6.21 per share. In addition, the
    Company granted each of Carl Ferenbach (on behalf of Berkshire Partners
    LLC) and Ari Q. Fitzgerald (on behalf of Hogan & Hartson L.L.P.) an option
    to purchase 25,000 shares of Common Stock with an exercise price of $3.28
    and $1.74 per share, respectively, in connection with his appointment as an
    independent director during 2002.

   In February 2003, the Board retained the services of the executive
   compensation consulting firm Towers Perrin to conduct research regarding
   equity compensation standards and trends for independent directors.
   Following receipt and review of the Towers Perrin analysis, the Board
   approved the granting of shares of Common Stock, pursuant to the Company's
   2001 Stock Incentive Plan, to the independent directors in lieu of options
   for 2003. At the first Board meeting of 2003, the Chairman of the Board, Mr.
   Martin, was granted 25,000 shares of Common Stock and each other independent
   director was granted 10,000 shares of Common Stock. The Board anticipates
   that it will continue granting stock awards in lieu of options to
   independent directors in future years.

..   Other Compensation. Each independent director is eligible to participate,
    at his cost and election, in the Company's medical and dental plans. A
    director who is also an employee of the Company receives no additional
    compensation for services as a director.

..   Certain Relationships and Related Transactions. On November 19, 1999, GE
    Capital Structured Finance Group, or SFG, made a $200,000,000 strategic
    investment in CCIC in exchange for 200,000 shares of CCIC's 81/4%
    Convertible Preferred Stock and warrants to purchase 1,000,000 shares of
    Common Stock. The warrants have an exercise price of $26.875 per share and
    are exercisable, in whole or in part, at any time for a period of five
    years following the issue date. The net proceeds of this investment were
    used to pay a portion of the purchase price for CCIC's transaction with GTE
    Wireless. The certificate of designations relating to the 81/4% Convertible
    Preferred Stock provides that so long as GE Capital or its permitted
    transferees hold at least 50%

                                      16



   of such 81/4% Convertible Preferred Stock, GE Capital will have the right to
   designate one nominee to be a member of the Board. William D. Strittmatter
   has served as a director of CCIC as the nominee of GE Capital since November
   1999 and is also Vice President of GE Capital and Chief Risk Officer for GE
   Commercial Finance.

   During 2002, CCIC and Berkshire Partners LLC ("Berkshire Partners") had a
   number of discussions with respect to Berkshire Partners and its affiliates
   making a direct investment in CCIC. The parties did not reach agreement on
   terms. As agreed prior to the commencement of due diligence, CCIC reimbursed
   Berkshire Partners approximately $500,000 for due diligence and industry
   analysis which was made available to CCIC (such amount represents less than
   half of the due diligence costs incurred by Berkshire Partners). Berkshire
   Partners subsequently decided to purchase securities of CCIC in the open
   market. Mr. Ferenbach is a Managing Director of Berkshire Partners, and Mr.
   Hack serves as an Advisory Director to Berkshire Partners.

   In February 2003, the Company retained the law firm of Hogan & Hartson
   L.L.P. to provide certain regulatory legal counsel relating to FCC Auction
   46. Mr. Fitzgerald, a director of CCIC, is a partner with Hogan & Hartson
   L.L.P.

   Edward W. Wallander, President and Chief Operating Officer of Crown Castle
   USA Inc., and David L. Ivy, who resigned as a director of the Board in
   August 2002, are brothers-in-law.

   by direct and indirect investment advisory subsidiaries (the "Adviser
   Subsidiaries") of Franklin Resources, Inc. ("FRI"). Such advisory contracts
   grant to such Adviser Subsidiaries all investment and/or voting power over
   the securities owned by such advisory clients. Therefore, such Adviser

   Exchange Act, the beneficial owner of the securities covered by the Schedule

   Shareholders may be deemed to be, for purposes of Rule 13d-3 under the

   entities advised by FRI subsidiaries. FRI, the FRI Principal Shareholders
   and each of the Adviser Subsidiaries disclaim any economic interest or
   beneficial ownership in any of the securities covered by this statement.
   FRI, the FRI Principal Shareholders, and each of the Adviser Subsidiaries
   are of the view that they are not acting as a "group" for purposes of
   Section 13(d) under the Exchange Act and that they are not otherwise
   required to attribute to each other the "beneficial ownership" of securities
   held by any of them or by any persons or entities advised by FRI
   subsidiaries.
   Percentage ownership shown is based on the number of shares of Common Stock
   outstanding as of April 9, 2002 rather than January 30, 2003.

   Partners LLC ("Berkshire Partners").
   The Schedule 13G states that Fifth Berkshire Associates LLC ("Fifth
   Berkshire") is the general partner of Fund V and Sixth Berkshire Associates
   LLC ("Sixth Berkshire") is the general partner of Fund VI. The managing
   members of Fifth Berkshire and Sixth Berkshire are: Bradley M. Bloom,

                                      26



   J. Christopher Clifford, Kevin T. Callaghan, Richard K. Lubin, Carl
   Ferenbach, Garth H. Greimann, Jane Brock-Wilson, David R. Peeler, Robert J.
   Small, and Ross M. Jones (the "Berkshire Principals"). The Berkshire
   Principals are also the managing members of Berkshire Investors and the
   managing directors of Berkshire Partners.
   One of the Berkshire Principals named above, Carl Ferenbach, is also a
   member of the Board of Directors of CCIC. Pursuant to a Form 4 filed by Mr.
   Ferenbach on February 24, 2003, Mr. Ferenbach reports holdings of 17,934,602
   shares of Common stock (including 1,844,067 shares issuable upon conversion
   of shares of 6.25% Cumulative Convertible Preferred Stock). The Form 4
   indicates that 17,828,946 of such shares are beneficially owned by Berkshire
   Partners LLC and certain affiliated investment entities. The Form 4 states
   that Mr. Ferenbach disclaims beneficial ownership of such shares except to
   the extent of his pecuniary interest (see "VI. Security Ownership of
   CCIC--Management Ownership").
   In addition, another member of the Board of Directors of CCIC, Mr. Randall
   A. Hack, serves as an Advisory Director of Berkshire Partners. In this
   capacity, Mr. Hack provides advice and counsel to Berkshire Partners and its
   affiliates based upon his business and relevant industry experience. Mr.
   Hack also participates with Berkshire Partners or its affiliates from time
   to time in selected investments, including investments in entities holding
   securities of CCIC including Common Stock.
   The Schedule 13G states that as of the date of the amendment to the Schedule
   13G (September 12, 2002), the Berkshire Entities collectively owned an
   aggregate of 17,102,915.80 shares of Common Stock. Such number of shares
   does not include 904,529 shares of Common Stock held on the date thereof by
   certain Berkshire Principals, other current or former employees of Berkshire
   Partners and trusts for the benefit of such persons (collectively, the
   "Other Berkshire Holders"). Since none of the Berkshire Entities has voting
   or investment power with respect to the Shares beneficially owned by the
   Other Berkshire Holders, the Berkshire Entities disclaim beneficial
   ownership of such shares.
   The Berkshire Entities (excluding Berkshire Partners) often make
   acquisitions in, and dispose of, securities of an issuer on the same terms
   and conditions and at the same time. Based on the foregoing and the
   relationships described in the Schedule 13G, the Schedule 13G states that
   the Berkshire Entities may be deemed to constitute a "group" within the
   meaning of Rule 13d-5 and for purposes of Section 13(d)(3) of the Exchange
   Act. As a member of a group, each Berkshire Entity may be deemed to share
   voting and dispositive power with respect to, and therefore beneficially
   own, the shares beneficially owned by members of the group as a whole. The
   Schedule 13G states that the filing of such Schedule 13G shall not be
   construed as an admission that the Berkshire Entities are a group, or have
   agreed to act as a group, or that the Berkshire Entities beneficially own
   those shares held by any other members of the group or the Other Berkshire
   Holders.
   The Schedule 13G also states that:
  .   Fund V is the direct beneficial owner of the 7,798,313.49 shares of
      Common Stock over which it has sole voting and sole dispositive power. As
      the sole general partner of Fund V, Fifth Berkshire may be deemed to
      beneficially own such shares of Common Stock held by Fund V. The filing
      of the Schedule 13G shall not be construed as an admission that Fifth
      Berkshire is, for the purpose of Section 13(d) of the Exchange Act, the
      beneficial owner of such shares held by Fund V.

                                      27



  .   Fund VI is the direct beneficial owner of the 8,406,098.64 shares of
      Common Stock over which it has sole voting and sole dispositive power. As
      the sole general partner of Fund VI, Sixth Berkshire may be deemed to
      beneficially own such shares of Common Stock held by Fund VI. The filing
      of the Schedule 13G shall not be construed as an admission that Sixth
      Berkshire is, for the purpose of Section 13(d) of the Exchange Act, the
      beneficial owner of such shares held by Fund VI.
  .   Berkshire Investors is the direct beneficial owner of the 873,503.66
      shares of Common Stock over which it has sole voting and sole dispositive
      power.
  .   Berkshire Partners is the direct beneficial owner of the 25,000 shares of
      Common Stock over which it has sole voting and sole dispositive power.
  .   By virtue of their positions as managing members of Fifth Berkshire,
      Sixth Berkshire and Berkshire Investors and managing directors of
      Berkshire Partners, the Berkshire Principals - including Carl Ferenbach,
      a director of CCIC - may be deemed to possess indirect beneficial
      ownership of the shares of Common Stock beneficially owned by Fund V,
      Fund VI, Berkshire Investors and Berkshire Partners. However, none of the
      Berkshire Principals, acting alone, has voting or investment power with
      respect to the shares beneficially owned by Fund V, Fund VI, Berkshire
      Investors or Berkshire Partners, and, as a result, each Berkshire
      Principal disclaims beneficial ownership of such shares of Common Stock.
(f)Based on an amendment to Schedule 13G filed on February 13, 2003,
   Massachusetts Financial Services Company has sole voting power over
   11,312,190 of such shares and sole dispositive power over all of such shares
   of Common Stock. Percentage ownership shown is based on the number of shares
   of Common Stock outstanding as of April 9, 2002 rather than February 13,
   2003.
(g)Based on a Schedule 13D filed on April 9, 1999, Cellco Partnership
   (currently doing business as Verizon Wireless), and Bell Atlantic
   Corporation (predecessor in interest to Verizon Communications Inc.
   ("Verizon")) report shared voting and dispositive power with respect to
   15,597,783 shares. The 15,597,783 shares are currently held by Crown
   Atlantic Holding Company LLC ("Crown Atlantic venture"), a joint venture
   owned 56.9% by CCIC's subsidiary, CCA Investment Corp., and 43.1% by an
   indirect subsidiary of Verizon (the "Verizon CA Sub"). Pursuant to the terms
   of the agreements relating to the Crown Atlantic venture, the Verizon CA Sub
   may trigger the dissolution of the joint venture at any time after March 31,
   2002, at which time all shares of Common Stock held by the joint venture
   will be distributed to the Verizon CA Sub. The Schedule 13D states that
   Verizon Wireless and Verizon disclaim beneficial ownership of the 15,597,783
   shares of Common Stock for all purposes other than Section 13 of the
   Exchange Act, as amended.
   The number of shares set forth in the table with respect to Verizon also
   includes 5,063,731 shares of Common Stock held by Crown Castle GT Holding
   Company LLC ("GT venture"), a joint venture owned 82.2% by CCIC's
   subsidiary, Crown Castle GT Company LLC, and 17.8% by an indirect subsidiary
   of Verizon (the "Verizon GT Sub"). Pursuant to the terms of the agreements
   relating to the GT venture, the Verizon GT Sub may trigger the dissolution
   of the joint venture at any time after January 31, 2003, at which time all
   shares of Common Stock held by the GT venture will be distributed to the
   Verizon GT Sub. As a result of the foregoing dissolution provisions, Verizon
   may be deemed to have shared voting and shared dispositive power with
   respect to the aggregate 20,661,514 held by the Crown Atlantic venture and
   the GT venture. For

                                      28



   purposes of the percentage ownership calculation set forth in the table, the
   shares held by the Crown Atlantic venture and the GT venture are included in
   the number of shares of Common Stock outstanding.
(h)Represents all outstanding shares of 81/4% Convertible Preferred Stock. Such
   shares of Preferred Stock are convertible into an aggregate of 7,441,860
   shares of Common Stock and vote with the Common Stock in proportion to the
   number of shares of Common Stock into which they are convertible. General
   Electric Capital Corporation also holds (1) warrants to acquire 1,000,000
   shares of Common Stock, (2) options to purchase 45,000 shares of Common
   Stock, and (3) 10,000 shares of Common Stock.

Employment, Termination and Change of Control Arrangements

..   Severance Agreements. As a condition to the grant of certain restricted
    stock awards in January 2003, CCIC entered into agreements containing
    non-compete, non-solicitation and minimum stock ownership provisions with
    each of the executive officers named above in "VII. Executive
    Compensation--Summary Compensation Table." The above described provisions
    are generally contained in a severance agreement between CCIC and each of
    the executive officers that replaces the prior severance agreement with
    such executive officer. The above provisions are contained in a separate
    agreement with Mr. Abery and his severance arrangement is similar to the
    arrangement described below for the other executive officers.

   Pursuant to each severance agreement, CCIC is required to provide severance
   benefits to the executive officer if such officer is terminated without
   cause (as defined in the severance agreement) or such officer terminates his
   or her employment with good reason (as defined in the severance agreement)
   (collectively, a "qualifying termination"). The severance agreement provides
   for enhanced severance benefits if the executive officer incurs a qualifying
   termination within the two-year period following a change in control (as
   defined in the severance agreement). Upon a qualifying termination that does
   not occur during the change in control period, the executive officer is
   entitled to:

  .   a lump sum payment equal to two times the sum of his base salary and
      annual bonus,

  .   a prorated cash amount equal to his annual bonus for the year of
      termination,

  .   continued coverage under specified welfare benefit programs for two years,

  .   immediate vesting of any outstanding options (which remain exercisable
      for two years following employment or service as a director, if
      applicable) and restricted stock awards (except restricted stock awards
      granted in January 2003), and

  .   continued vesting of restricted stock awards granted in January 2003 for
      three years after termination, as if the executive officer were an
      employee of CCIC.

   Upon a qualifying termination during the change in control period, the
   executive officer is entitled to:

  .   receive a lump sum payment equal to three times the sum of his base
      salary and annual bonus,

  .   a prorated cash amount equal to his annual bonus for the year of
      termination,

  .   continued coverage under specified welfare benefit programs for three
      years, and

  .   immediate vesting of any outstanding options (which remain exercisable
      for two years following employment or service as a director, if
      applicable) and restricted stock awards.

   Each of the severance agreements also has provisions that generally prohibit
   the executive officer, for a period of 12 months following the termination
   of such officer's employment with CCIC, from (1) engaging in business
   activities relating to wireless

                                      33



   communication or broadcast towers which compete with CCIC or its affiliates
   in the United States, the United Kingdom or Australia and (2) soliciting
   employees of CCIC and its affiliates. Further, the agreements contain
   provisions requiring each of the executive officers to own and hold at all
   times during his employment with CCIC, a specified number of shares of
   Common Stock as follows, which number does not include unvested restricted
   stock which remain subject to transfer and forfeiture restrictions:



                                                                        Minimum Share

Compensation Committee 2002 Report

The Compensation Committee ("Committee") of the Board of Directors ("Board") of
Crown Castle International Corp. ("CCIC") reviews, evaluates and establishes
the salary levels of the CCIC executive officers (the chief executive officer
("CEO") and the officers reporting directly to the CEO--currently 9 persons
including the CEO) and administers CCIC's stock option and other compensatory
plans. The current members of the Committee are Lee W. Hogan, Carl Ferenbach
and Ari Q. Fitzgerald. The following report presents the Committee's summary of
CCIC's compensation programs and policies and describes the bases for
compensation of CCIC's executive officers.

..   Goals. The principal goals of CCIC's executive compensation policy are to
    provide competitive compensation opportunities to attract and retain
    qualified and productive executive employees; to motivate executives to
    meet and exceed corporate financial and operational goals; and to create
    meaningful links between corporate performance, individual performance and
    rewards. It has been CCIC's traditional executive compensation policy that
    a significant portion of the compensation paid to the executive officers
    should be based on CCIC's results of operations and the growth in value of
    its equity. CCIC's executive officer compensation program is designed to
    align executive officer compensation with stockholder interests.
    Specifically, the program seeks to:

  .   incentivize and reward executive officers for sound business management
      and improvement in stockholder value,

  .   balance its components so that the accomplishment of short-term and
      long-term operating and strategic objectives is encouraged and recognized,

  .   encourage achieving objectives within a team environment, and

  .   attract, motivate and retain executive officers necessary for the
      long-term success of CCIC.

..   Compensation Program. For the year 2002, as in prior years, the Committee
    reviewed the compensation programs of certain competitors and "peers" in
    similar industries. All of the companies used by the Committee as the peer
    group for evaluating CCIC's executive officer compensation offer base
    salary, equity-based compensation and bonuses.

   The Committee believes that using equity-based compensation and
   performance-based bonuses as components of overall compensation helps align
   executive officers' interests with those of the stockholders. The value of
   equity-based compensation to an executive officer increases as the market
   price of CCIC's stock increases. Therefore, CCIC's operating goals and
   individual incentives are targeted towards those activities that increase
   stockholder value. If CCIC does not perform or does not meet its objectives,
   the equity-based compensation is of less value and performance-based bonuses
   are reduced.

                                      35



   In the Committee's assessment of compensation levels, the Committee takes
   into consideration performance relative to the individual responsibilities
   of the executive officers and considerations of internal equity, as well as
   the financial performance of CCIC relative to its goals. The Committee also
   considers the competitiveness of the entire executive compensation package
   and each of its individual components. The Committee reviews CCIC's overall
   performance and each executive officer individually to determine salary and
   bonus adjustments and to determine equity-based awards.

..   Salaries. The Committee approves the annual salaries for all executive
    officers of CCIC. The Committee reviews recommendations made by the CEO
    with regard to salary adjustments for executive officers other than
    himself, and then either approves or amends these recommended salary
    adjustments. The Committee independently reviews the performance of the CEO
    and determines an appropriate salary based on the criteria set forth above,
    as well as input from outside compensation consultants and other sources.
    In 2002, the Committee retained the services of the executive compensation
    consulting firm Towers Perrin to review CCIC's overall compensation
    packages for executive officers. For 2002, the executive officers received
    a merit increase to their base salaries and, where appropriate, also
    received a market adjustment to more closely align their compensation with
    the market analysis prepared by Towers Perrin. Mr. Kelly was among those
    executive officers who received a market adjustment, reflecting his new
    duties as CEO of CCIC.

..   Incentive Compensation. Each year, the Committee considers incentive
    bonuses for the executive officers of CCIC using similar methodologies to
    those employed in evaluating salaries for the executive officers. For 2002,
    as in prior years, achievement of certain performance targets were used by
    the Committee in awarding bonuses. The performance targets may be based on
    one or more business criteria, or any combination thereof, including but
    not limited to:

  .   cash flow from operations,

  .   free cash flow (net cash from operating activities less capital
      expenditures),

  .   other measures of financial performance, and

  .   additional components at the Committee's discretion.

   Depending on the level at which the performance goals are met, the CEO and
   the other executive officers generally are eligible for cash bonuses
   approximating 50 to 100 percent of their base salaries. Bonuses were paid to
   an executive officer for 2002 based upon the level at which such officer's
   respective business segments achieved performance goals. In addition,
   bonuses were also paid to certain officers for significant individual
   contributions.

                                      36



..   Equity-Based Compensation.  Historically, the CCIC executive officers were
    granted discretionary annual incentive stock options pursuant to the
    Amended and Restated 1995 Stock Option Plan, based upon individual and
    corporate performance. Following a change in certain management positions,
    the Board in September 2001 (following review and recommendation by the
    Committee) granted certain front-loaded performance accelerated options
    under the Amended and Restated 1995 Stock Option Plan to CCIC executive
    officers and certain other key employees of CCIC. The CCIC executive
    officers received no options or other equity-based compensation in 2002.

   From January through March 2003, CCIC granted, pursuant to its 2001 Stock
   Incentive Plan, approximately 5,805,000 shares of restricted stock
   ("Restricted Stock") to over 350 of its employees, including 1,770,000
   shares of Restricted Stock to the CEO and six other CCIC executive officers.
   The Restricted Stock was issued in lieu of CCIC's annual stock option grants
   for 2003.

   The shares of Restricted Stock were granted subject to the terms of
   Restricted Stock Agreements executed in connection with such grants and will
   generally vest (i.e., the transfer and forfeiture restrictions terminate) in
   the largest aggregate number of shares vesting pursuant to either (i) Time
   Vesting (defined below) or (ii) Performance Vesting (defined below). The
   Restricted Stock vests over time at 10%, 15%, 20%, 25% and 30% respectively,
   on each November 14 for the years 2003 through 2007 ("Time Vesting").
   Performance Vesting relates to target increases in the per share closing
   price of the CCIC's common stock ("Stock") at or above a base price of
   $3.69. The base price is equal to the average closing price per share of
   Stock for a period of five trading days established by the Board at the time
   it approved the granting of the Restricted Stock. If and when the Stock
   closes at or above per share prices equal to 150% of the base price ($5.54),
   225% of the base price ($8.30) and 337% of the base price ($12.45) for 20
   consecutive trading days, 33% of the Restricted Stock performance vests upon
   reaching each price target ("Performance Vesting"). If a restricted
   stockholder's employment with the Company is terminated, any remaining,
   unvested shares of Restricted Stock which such individual holds are
   generally forfeited and surrendered to CCIC, subject to the provisions of
   any severance arrangements with CCIC. Most of the CCIC executive officers
   have severance arrangements that cause the Restricted Stock to vest or
   continue vesting following termination.

   The grant of Restricted Stock to certain officers of CCIC, including all of
   the CCIC executive officers, was conditioned upon such officers executing
   agreements containing certain restrictions, including non-compete,
   non-solicitation and/or minimum stock ownership provisions (for a
   description of such agreements, see "VII. Executive
   Compensation--Employment, Termination and Change of Control Arrangements").

..   Compensation of the Chief Executive Officer. For 2002, the Committee set
    Mr. Kelly's base salary as President and CEO of CCIC at $425,000. Mr. Kelly
    also received

                                      37



   a bonus of $382,600 (or 90% of his base salary) for his service during 2002.
   In addition, in 2003, the Company granted Mr. Kelly 600,000 shares of
   Restricted Stock subject to the vesting terms described above under
   "Equity-Based Compensation". In determining the level of Mr. Kelly's salary,
   bonus and Restricted Stock award, the Committee considered the market in
   which CCIC competes, the compensation of similarly situated officers at
   certain competitors and "peers" in similar industries, CCIC's performance in
   2001 and 2002, and Mr. Kelly's contributions to corporate performance. In
   addition, in establishing Mr. Kelly's compensation for 2002, the Committee
   also considered the market analysis prepared by Towers Perrin.

..   Summary. Section 162(m) of the Internal Revenue Code includes potential
    limitations on the deductibility of compensation in excess of $1 million
    paid to the Chief Executive Officer and each of the other four highest
    compensated executive officers. It is the Committee's intent to adopt
    policies to obtain maximum tax deductibility of executive compensation
    consistent with providing motivational and competitive compensation, which
    is truly performance-based. However, it is also the Committee's intent to
    balance the effectiveness of its plans and compensation policies against
    the materiality of any possible lost deductions.

   The Committee believes that CCIC's executive compensation policies and
   programs serve the interests of the stockholders and CCIC effectively. The
   Committee believes the various compensation programs are appropriately
   balanced to provide motivation for executives to contribute to CCIC's
   overall success and enhance the value of CCIC for the stockholders' benefit.
   When performance goals are met or exceeded, resulting in increased value to
   stockholders, executives are rewarded commensurately. The Committee will
   continue to monitor the effectiveness of CCIC's total compensation program
   and continue to make proposals where appropriate, in order to meet the
   current and future needs of CCIC.

   Respectfully submitted by the Compensation Committee of the Board of
   Directors of Crown Castle International Corp.

directors, as defined in the rules and regulations of the NYSE. Upon the
recommendation of the Audit Committee and in compliance with the regulations of
the NYSE, the Board has adopted an Audit Committee Charter setting forth the
requirements for the composition of the Audit Committee, the qualifications of

Audit Committee 2002 Report

To our Stockholders:

Management of Crown Castle International Corp. ("Company") has the primary
responsibility for preparing the Company's financial statements and
implementing the Company's reporting process, including the Company's system of
internal controls. On behalf of the Board of Directors, the Audit Committee,
among other duties, performs an oversight role relating to the Company's
financial reporting processes and systems of internal control, the independence
and the performance of the independent accountants, and the performance of the
internal accountants.

Management has represented to the Audit Committee that the Company's
consolidated financial statements were prepared in accordance with generally
accepted accounting principles, and the Audit Committee has reviewed and
discussed the consolidated financial statements with management and KPMG, the
Company's independent accountants. The Audit Committee has discussed with the
independent accountants their evaluation of the accounting principles,
practices and judgments applied by management, and the Committee has discussed
any items required to be communicated to it by KPMG in accordance with
standards established by the American Institute of Certified Public Accountants
(including Statement on Auditing Standards 61).

The Audit Committee has received from KPMG a letter describing any
relationships with the Company that may bear on its independence (as required
by Independence Standards Board Standard No. 1) and has discussed with KPMG its
independence from the Company and its management. The Committee has reviewed
and approved the audit fees of KPMG. It has also reviewed and approved
non-audit services and fees to assure compliance with the Company's and the
Committee's policies restricting KPMG from performing services that might
impair its independence.

The Audit Committee discussed with KPMG the overall scope of and plans for its
audit. The Committee has met with KPMG, separately and together, with and
without management present, to discuss the Company's financial reporting
processes and internal controls. The

                                      40



Committee has reviewed significant audit findings prepared by KPMG and those
prepared by the Company's staff, together with management's responses.

IX. OTHER MATTERS

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires CCIC's directors
and executive officers, and persons who own more than 10% of a registered class
of CCIC's equity securities, to file with the SEC and the NYSE reports of
ownership and changes in ownership of Common Stock and other equity securities
of CCIC. Executive officers, directors and greater than 10% stockholders are
required by SEC regulation to furnish the Company with copies of all Section
16(a) forms they file.

Based on the review of copies of such reports furnished to the Company and
written representations that no other reports were required, the Company
believes that, during the 2002 fiscal year, CCIC's executive officers,
directors and greater than 10% beneficial owners complied with all Section
16(a) filing requirements applicable to them, except Robert F. McKenzie who
filed a Form 4 in September 2002 relating to two transactions that occurred in
July 2002.
