I. Information About Voting Solicitation of Proxies. The Board of Directors ("Board") of Crown Castle International Corp. ("CCIC") is soliciting proxies for use at the 2000 Annual Meeting of CCIC and any adjournments of that meeting. CCIC first sent this proxy statement, the accompanying form of proxy and the CCIC Annual Report for 1999 to its stockholders on April 24, 2000. Agenda Items. The agenda for the Annual Meeting is to: 1. Elect three (3) class II directors for a term of three years; 2. Ratify the appointment of KPMG LLP as our independent auditors for 2000; 3. Conduct other business properly before the meeting. Who can Vote. You can vote at the Annual Meeting if you are a holder of CCIC's common stock, par value of $0.01 per share ("Common Stock"), or CCIC's Class A common stock, par value of $.01 per share ("Class A Common Stock"), on the record date. The record date is the close of business on March 27, 2000. You will have one (1) vote for each share of Common Stock and Class A Common Stock, except the holders of Class A Common Stock do not vote on the class II directors. As of March 27, 2000, there were 148,813,170 shares of Common Stock and 11,340,000 shares of Class A Common Stock outstanding. All of such outstanding shares are entitled to vote, other than the 15,597,783 shares of Common Stock held by Crown Atlantic Holding Company LLC, the limited liability company for our joint venture with Bell Atlantic Mobile, which are not entitled to vote or be counted for quorum purposes while held by such venture. In addition, the outstanding shares of our 8 1/4% Cumulative Convertible Redeemable Preferred Stock (the "8 1/4% Convertible Preferred Stock") vote on an as converted basis with the other shares entitled to vote as a single class (as of the record date such shares of Preferred Stock were convertible into an aggregate of 7,441,860 shares of Common Stock). How to Vote. You may vote in two (2) ways: . You can come to the Annual Meeting and cast your vote there. . You can vote by signing and returning the enclosed 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 us on the proxy card to vote differently, we plan to vote all signed and returned proxies FOR the Board nominees for class II directors and FOR Agenda item 2. We do not now know of any other matters to come before the Annual Meeting. If they do, proxy holders will vote the proxies in their best judgment. 3

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 to the Secretary of CCIC; . Delivering a properly executed, later-dated proxy; or . Attending the Annual Meeting and voting in person. The Quorum Requirement. We need a quorum of stockholders to hold a valid Annual Meeting. A quorum will exist as to the election of class II directors if the holders of at least a majority of the outstanding Common Stock (including votes attributtable to the 8 1/4% Convertible Preferred Stock) entitled to vote either attend the Annual Meeting in person or are represented by proxy. A quorum will exist as to other matters if the holders of at least a majority of the outstanding Common Stock (including votes attributtable to the 8 1/4% Convertible Preferred Stock) and Class A Common Stock entitled to vote 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 does not have the authority to do so. Vote Required for Action. Directors are elected by a plurality vote of shares of Common Stock (including votes attributtable to the 8 1/4% Convertible Preferred Stock) present in person or by proxy at the meeting. Ratification of KPMG LLP as CCIC's independent auditors for 2000 requires the affirmative vote of a majority of the shares of Common Stock (including votes attributtable to the 8 1/4% Convertible Preferred Stock) and Class A Common Stock present in person or by proxy at the meeting. Generally, other actions require the affirmative vote of the majority of shares of Common Stock (including votes attributtable to the 8 1/4% Convertible Preferred Stock) and Class A Common Stock present in person or by proxy at the meeting. Abstentions and broker non- votes have the effect of a no vote on matters other than director elections. Stockholders Agreement. On August 21, 1998, we entered into the Stockholders Agreement (the "Stockholders Agreement") with certain of our stockholders to provide for certain rights and obligations of us and such stockholders, including rights and obligations relating to the election of directors. The Stockholders Agreement, as it relates to the election of directors, is discussed in Section VI of this proxy statement. 4

II. Proposals To Be Voted On 1. The Election of Directors CCIC has three classes of directors of as nearly equal size as possible plus the Class A Common Stock directors. 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 2000 Annual Meeting. The nominees for class II directors this year are: David L. Ivy, William D. Strittmatter and John P. Kelly. Mr. Ivy is the nominee of the CEO, and Mr. Strittmatter is the nominee of GE Capital pursuant to the terms of CCIC's 8 1/4% Cumulative Convertible Redeemable Preferred Stock. The Board expects that each of the nominees for class II directors will be able and willing to serve as directors. 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 recommends a vote FOR the election of David L. Ivy, William D. Strittmatter and John P. Kelly as class II directors. 2. Ratification of Appointment of Independent Auditors The Audit Committee of the Board has recommended that KPMG LLP continue to serve as CCIC's independent auditors for 2000. KPMG LLP has served as CCIC's independent auditors since 1995. We expect 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. The Board recommends a vote FOR ratification of the appointment of KPMG LLP as independent auditors for the year 2000. 5

(b) Based on a Schedule 13G filed on February 15, 2000, BellSouth Corporation reports sole voting and dispositive power with respect to all such shares. Percentage ownership shown is calculated based on the number of shares of Common Stock outstanding as of March 31, 2000, rather than February 15, 2000. (c) Crown Atlantic Holding Company LLC is a joint venture 61.5% owned by our subsidiary, CCA Investment Corp. and 38.5% owned by Bell Atlantic Mobile and certain of its affiliates. The principal business address of Crown Atlantic Holding Company LLC is 375 Southpointe Blvd., Canonsburg, PA 15317. The Common Stock held by Crown Atlantic Holding Company LLC cannot be voted and is not counted for quorum purposes pursuant to Delaware law so long as it is held by the venture. For purposes of this percentage ownership calculation, shares held by Crown Atlantic Holding Company LLC are included in the number of shares of Common Stock outstanding. (d) The aggregate Preferred Stock number represents all outstanding 8 % Cumulative Convertible Redeemable Preferred Stock. Such shares of Preferred Stock vote with the Common Stock in proportion to the number of shares of Common Stock into which they are convertible.

for 1,000,000 shares of Common Stock and 7,441,860 shares of Common Stock issuable upon conversion of the 8 1/4% Cumulative Convertible Redeemable Preferred Stock. (e) Based on a Schedule 13G filed on February 15, 2000, Janus Capital Corporation reports sole voting and dispositive power with respect to all such shares as a result of acting as investment advisor to various investment companies.

The Schedule 13G also indicates that Thomas H. Bailey, president and chairman of the board and 12.2% equity owner of Janus Capital, may be deemed to have the power to exercise or direct the voting and/or dispositive power that Janus Capital may have over such shares. Mr. Bailey specifically disclaims beneficial ownership over such shares in the Schedule 13G. Percentage ownership shown is calculated based on the number of shares of Common Stock outstanding as of March 31, 2000, rather than February 15, 2000.

Without taking into account the exchange of the CCUK capital stock or any conversions of Class A Common Stock (13,872,396 shares), TFN currently has approximately 10.4% of the outstanding shares of Common Stock. Assuming the exchange of the CCUK capital stock and the conversion of all Class A Common Stock into Common Stock, TdF and TFN combined would have approximately 26.3% of the voting power of Common Stock. The principal business address of TFN is c/o TeleDiffusion de France International S.A., 10 Rue d'Oradour sur Glane, 75732 Paris 15 France. 25

Termination and Change of Control Arrangements . Severance Agreements. Under severance agreements entered into with certain executive officers, CCIC is required to provide severance benefits to these executive officers if they are terminated without cause (as defined in the severance agreements) or they terminate their employment with good reason (as defined in the severance agreements) (collectively, a "qualifying termination"). The severance agreements provide for enhanced severance benefits if the executive officers incur a qualifying termination within the two-year period following a change in control (as defined in the severance agreements). Upon a qualifying termination that does not occur during the change in control period, an eligible executive officer is entitled to: (1) a lump sum payment equal to two times the sum of his base salary and annual bonus, (2) continued coverage under specified welfare benefit programs for two years, and (3) immediate vesting of any outstanding options and restricted stock awards. Upon a qualifying termination during the change in control period, an eligible executive officer is entitled to: (1) receive a lump sum payment equal to three times the sum of his base salary and annual bonus, (2) continued coverage under specified welfare benefit programs for three years, and (3) immediate vesting of any outstanding options and restricted stock awards. . 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. 29

Report of the Compensation Committee on Executive Compensation . Goals. CCIC's executive officer compensation program is designed to align total executive officer compensation with stockholder interests. The program: . attracts, incents and rewards executive officers for sound business management and improvement in stockholder value . balances its components so that the accomplishment of short- and long- term operating and strategic objectives are encouraged and recognized . requires achieving objectives within a "high-performance" team environment . attracts, motivates and retains executive officers necessary for the long-term success of CCIC . Compensation Program. CCIC's compensation program is designed to attract and retain skilled individuals who are seasoned industry professionals. CCIC is competing against well-funded and established telecommunications companies for its talent. Published studies show that over 95% of major U.S. corporations pay bonuses and grant some form of stock-based awards to company executives. All of the companies used by the Compensation Committee as the "peer group" for evaluating our executive officer compensation offer base salary, stock options and bonuses. Our salaries are at market levels. Importantly, we have emphasized the stock incentive portion in our efforts to attract and retain qualified executive officers. As a recently public company, the equity-based component of incentive plans have become a critical element in being able to attract the talent we need to continue our successful acquisitions and growth plans and the long-term objectives are promoted by executive management and approved by the Board. We believe that using stock options and performance-based bonuses match executive officers' interests with those of the stockholders. The market price of our stock must increase in order for an executive officer to receive the value of a stock option. Therefore, our operating goals and individual incentives will be targeted towards those activities that increase stockholder value. If CCIC does not perform, the options are of less value and performance-based bonuses are not paid. . Salaries. The annual salaries for executive officers for the following fiscal year are recommended by the Compensation Committee and approved by the Board. Recommendations for annual salaries for the executive officers other than the Chief Executive Officer are made by the Chief Executive Officer to the Compensation Committee, based on his first hand knowledge of the contribution of each executive officer to his or her respective area of concentration and responsibility. There is no precise test or formula by which the recommended salary is related to performance. Rather than follow such a rigid standard, the Committee believes that CCIC's interests 30

are best served by having a flexible compensation policy that gives the Committee the leeway to fix compensation after considering the factors enumerated above and evaluating each situation as required. . Incentive Compensation. We have compensation arrangements for executive officers that include annual cash bonuses for the achievement of certain performance targets such as the improvement of earnings before interest, taxes, depreciation and amortization. Achieving high standards of business performance are rewarded financially, and significant compensation is at risk if these high standards are not met. For executive officers, target cash bonuses approximate 50 to 100 percent of base salary. . Stock Options. Executive officers are granted discretionary annual incentive stock options pursuant to the Amended and Restated 1995 Stock Option Plan. As in the case of salaries, the Compensation Committee does not use a precise test or formula of corporate performance in determining either the timing or number of shares subject to options to be granted. We have a discretionary strategic acquisition option bonus pool of up to 1.29% of the purchase price or deal value for major acquisitions, mergers, new business initiatives and similar transactions that are consistent with our mission statement and long-term business plans. The options are part of the Amended and Restated 1995 Stock Option Plan and subject to review by the Compensation Committee. We contemplate that the options will generally be: . granted subject to close of the applicable transaction . priced at the fair market value at the close of business one day prior to the public announcement of the applicable transaction . vested at the closing of the applicable transaction as to 33 1/3% of the option shares . vested as to the remaining options over five years with accelerated vesting, in trauches, if certain price performance criteria for the Common Stock is obtained In summary, the Company has an appropriate and competitive compensation program, which is designed to increase stockholder value and attract and retain qualified executives.

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 NASDAQ 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 us and written representations that no other reports were required, we believe that, during the 1999 fiscal year, all Section 16(a) filing requirements applicable to CCIC's executive officers, directors and greater than 10% beneficial owners were complied with except for (i) Bruno Chetaille failed to file either a Form 4 or Form 5 for the 5,000 stock options granted in January 1999 and (ii) potential filings by certain stockholders which may be deemed to be a 10% beneficial owner as a result of the Stockholders Agreement. Such stockholders are potentially members of a group for Section 16(a) reporting purposes and inadvertently failed to timely file Form 4 reports representing such ownership which potentially should have been filed at the time of their disposition of CCIC Common Stock during 1999. The potential group of beneficial owners which may have failed to timely file a Form 4 consists of New York Life Insurance Company, American Home Assurance Company, PNC Venture Corp., Harvard Private Capital Holdings, Inc., Fay Richwhite Communications Limited, Prime VIII, L.P., The Northwestern Mutual Life Insurance Company, and certain of their affiliates. The delinquent Form 4 reports involve an aggregate of 5,604,857 shares of Common Stock, and each of the delinquent stockholders holds an economic interest which is significantly less than 5% and is not entitled to designate a director under the Stockholders Agreement. 33
