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).

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.

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. 29

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 Name Title Holdings - ---- ----- ------------- John P. Kelly........... Chief Executive Officer & President 65,000 W. Benjamin Moreland.... Senior Vice President, Chief Financial Officer & Treasurer 43,000 E. Blake Hawk........... Executive Vice President & General Counsel 47,000 Peter G. Abery.......... President & Managing Director, Crown Castle UK Limited 39,000 Edward W. Wallander..... President & Chief Operations Officer, Crown Castle USA, Inc. 43,000 An executive officer who does not currently own the required minimum number of shares of Common Stock has until November 14, 2004 to acquire such shares. .. Stock Options. All unvested stock options granted to executive officers vest upon a change in control. The accelerated vesting provisions relating to a change in control are contained in the individual stock option agreements. .. Employment Agreement. In December 2001, the Company entered into an employment agreement with Peter G. Abery in connection with Mr. Abery's appointment as President and Managing Director of CCUK. The contract has a term from January 1, 2002 through December 2004. The agreement provides that Mr. Abery shall receive the following compensation during the term: . a base salary of $250,000 per year, . eligibility for an annual bonus of 75% of base salary provided performance hurdles are met, . a one-time grant of options to purchase 100,000 shares of the Company's common stock at an exercise price of $10.50 per share, . bonus of up to $75,000 to be paid upon completion of the term, . health care and other employee welfare benefits, and . access to an employee vehicle, and relocation, career transition and housing assistance. Mr. Abery's base salary is currently denominated in U.S. dollars and paid in British pounds sterling. The employment agreement with Mr. Abery is in the process of being amended to take into account certain currency adjustments and to denominate his base salary in Australian dollars, Mr. Abery's home currency. 34

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.

VIII. AUDIT COMMITTEE MATTERS The Board has established an Audit Committee comprised entirely of independent 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 its members and the responsibilities of the Audit Committee. In addition, in accordance with regulations promulgated by the SEC, the Audit Committee has issued the following report. 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.

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. Stockholder Proposals for 2004 Annual Meeting Stockholders wishing to have a proposal included in the Board's 2004 proxy statement must submit the proposal so that the secretary of CCIC receives it at CCIC's principal executive offices no later than December 18, 2003. If the date of the 2004 Annual Meeting is changed by more than 30 days from the date of the 2003 Annual Meeting, the deadline for submitting proposals to be included in the Board's 2004 proxy statement is a reasonable time before the Company begins to print and mail its proxy materials for its 2004 Annual Meeting. Stockholders may make nominations for directors and introduce proposals or other business to be considered at the 2004 Annual Meeting provided such nominations and proposals are in accordance with CCIC's bylaws and involve proper matters for stockholder action. Such stockholder nominations and proposals and other business for the 2004 Annual Meeting must be received not less than 90 days (February 29, 2004) nor more than 120 days (January 30, 2004) before May 29, 2004 (which will then be the first anniversary of the preceding year's meeting) at CCIC's principal executive offices, 510 Bering, Suite 500, Houston, TX 77057, Attn: Corporate Secretary. If the 2004 Annual Meeting is advanced by more than 30 days, or delayed by more than 90 days, from the date of the 2003 Annual Meeting, the nomination or proposal must be delivered not earlier than the 120th day prior to the 2004 Annual Meeting and not later than the later of the 90th day prior to the 2004 Annual Meeting or the 10th day following the announcement of the change in the 2004 Annual Meeting date. The notice of nominations for the election of directors must set forth certain information concerning the stockholder giving the notice and each nominee. A copy of the applicable bylaw provision may be obtained, without charge, upon written request to the Corporate Secretary. 42

If the date of the 2004 Annual Meeting is advanced or delayed by more than 30 calendar days from the date of the 2003 Annual Meeting, the Company shall, in a timely manner, inform shareholders of such change, by including a notice, under Item 5, in its earliest possible quarterly report on Form 10-Q. The notice will include the new deadline for submitting proposals to be included in the Board's 2004 proxy statement and the new date for determining whether the Company has received timely notice of a nomination or proposal. Expenses Relating to this Proxy Solicitation CCIC will pay all expenses relating to this proxy solicitation. In addition to this solicitation by mail, CCIC officers, directors, and employees may solicit proxies by telephone or personal call without extra compensation for that activity. CCIC also expects to reimburse banks, brokers and other persons for reasonable out-of-pocket expenses in forwarding proxy material to beneficial owners of CCIC stock and obtaining the proxies of those owners. The Company will furnish without charge to each person whose proxy is being solicited, upon request of any such person, a copy of the Annual Report on Form 10-K for the fiscal year ended December 31, 2002 as filed with the Securities and Exchange Commission, including the financial statements and schedules thereto, but not the exhibits.
