                        CROWN CASTLE INTERNATIONAL CORP.

                       (Incorporated Under the Law of the
                               State of Delaware)


This document certifies that, for value received, [OPTION GRANTEE'S NAME]
("Holder") is entitled, subject to the terms and conditions set forth herein, to
purchase from CROWN CASTLE INTERNATIONAL CORP., a Delaware corporation
("Company"), an aggregate of [number of option shares] fully paid and
nonassessable shares of the common stock, $.01 par value, of the Company (such
shares of the Company's common stock being herein called the "Option Shares" and
all shares of the Company's common stock being herein called the "Stock"), upon
payment of the purchase price of [purchase price per share in US dollars ($
amount)] per Option Share (the "Purchase Price"), at any time after the date
hereof ("Effective Date") and on or before 5:00 P.M. (Houston time) [option
termination date] ("Termination Date"), subject to the provisions of this Option
("Option"). The number and character of the Option Shares covered hereby and the
Purchase Price thereof are subject to restrictions and adjustments as provided
herein. This Option is granted to the Holder pursuant to the 2001 Stock
Incentive Plan ("Plan") of the Company. This Option is subject to all the terms
of the Plan and this Option Agreement. This option is a non-qualified stock
option ("NSO") taxable pursuant to Section 83 of the Internal Revenue Code of
1986, as amended ("Code").

1. Exercise of Option. Upon delivery of written notice to the Company setting
forth the number of Option Shares with respect to which this Option is being
exercised in the manner described in Section 16 and accompanied by payment in
form and substance satisfactory to it, or by shares of Stock valued at the fair
market value of the Stock on the date of exercise as determined in accordance
with the Plan (subject to the limitations in Section 2 below), to the Company of
the Purchase Price for the Option Shares to be purchased, the Company shall
promptly issue one or more certificates evidencing the number of Option Shares
being purchased. This Option may be exercised either in whole or in part and, if
in part, from time to time in part; provided, however, that this Option may not
be exercised for less than 100 Option Shares (or such lesser number of vested
Option Shares as is covered by this Option); and, provided further, that this
Option may only be exercised by the Holder for the purchase of whole Option
Shares and not fractions thereof unless the Company otherwise agrees.

<PAGE>


The Company agrees that the Option Shares so purchased shall be and are deemed
to be issued to the Holder hereof as the record owner of such Option Shares as
of the close of business (or an earlier reasonable deadline timeframe taking
into account the stock is publicly traded) on the date on which this Option
shall have been exercised and payment made for such Option Shares as aforesaid.

2. Payment for Stock. Payment for shares of Stock purchased pursuant to this
Option shall be made in full. Payment for shares of Stock purchased under this
Option may be made in cash, Stock or a combination of cash and Stock. In the
event that Stock is utilized in consideration for the purchase of Stock upon the
exercise of this Option, then such Stock shall be valued as provided in the
Plan.

Notwithstanding the above, if shares of Stock are listed on a national exchange
in the United States, a sufficient number of Shares acquired upon exercise of
the Option may be sold by the Committee (as defined in the Plan) (including its
agent) to satisfy any unpaid obligation of the Holder relating to exercise of
the Option including, without limitation, any purchase price or withholding
obligation. The Committee may elect the above payment method in lieu of
accepting Stock as payment for exercise of the Option.

3. Reservation of Stock. The Company covenants and agrees that (a) it has or
will at all appropriate times, so long as this Option is outstanding, reserve
and keep available out of its treasury Stock and/or authorized but unissued
Stock, solely for the purpose of issuing Option Shares, from time to time, upon
the exercise of this Option, an adequate number of shares of Stock for delivery
at the times and in the manner provided herein upon exercise of this Option; (b)
the Option Shares delivered upon exercise of this Option shall be validly issued
and outstanding and fully paid and nonassessable shares of Stock; and (c) it
will pay when due any and all federal and state original issue or similar taxes
which may be payable in respect of the issuance of this Option or of any shares
of Stock upon exercise of this Option. The Company shall not be required to pay
any transfer tax which may be payable with respect to any transfer of this
Option, the issuance of certificates of Stock in a name other than that of the
registered Holder of this Option or any transfer of Option Shares, all such tax
being payable by the Holder.

4. Restrictions on Transfer. Except as otherwise herein provided, the Option
shall not be transferable otherwise than by (i) will or the laws of descent and
distribution or (ii) pursuant to a qualified domestic relations order as defined
by the Code, or Title I of the Employee Retirement Income Security Act of 1974,
as amended, or the rules thereunder. The Option may be exercised, during the
lifetime of the Holder, only by the Holder or a permitted transferee. More
particularly (but without limiting the generality of the foregoing), the Option
may not be assigned, transferred (except as provided herein), pledged or
hypothecated in any way, shall not be assignable by operation of law and shall
not be subject to execution, attachment or similar process. Any attempted
assignment, transfer, pledge, hypothecation or other disposition of the Option
contrary to the provisions hereof shall be null and void and without effect.
Notwithstanding the above, an Option which is an NSO may be assigned or
transferred by (i) a Holder which is an outside director to the employer of such
director or (ii) a Holder which is a natural person (including any permitted
transferee as provided below) to (a) the Holder's spouse, children or
grandchildren


                                       2

<PAGE>

(including adopted children, stepchildren and grandchildren) ("Family Member"),
(b) a trust for the benefit of Holder and Holder's Family Members, (c) a
partnership or limited liability companywhose only partners or shareholders
(i.e. members) are the Holder and Family Members of the Holder; provided, that
the transfer or assignment of the Option must comply with any applicable federal
or state securities laws or any other applicable law or regulation thereunder.

5. Changes in the Company's Capital Structure. The existence of this Option
shall not affect in any way the right or power of the Company or its
stockholders to make or authorize any or all adjustments, recapitalization,
reorganizations or other changes in the Company's capital structure or its
business, or any merger or consolidation of the Company, or any issue of bonds,
debentures, Stock, preferred or prior preference stock ahead of or affecting the
Stock or the rights thereof, or the dissolution or liquidation of the Company,
or any sale or transfer of all or any part of its assets or business, or any
other corporate act or proceeding, whether of a similar character or otherwise.

If the Company shall effect a subdivision or consolidation of shares or other
capital readjustment, the payment of a stock dividend or other increase or
reduction of the number of shares of Stock outstanding without receiving
compensation therefor in money, services or property, then (a) the number, class
and per share price of shares of stock subject to this Option shall be
appropriately adjusted in such a manner as to entitle the Holder to receive upon
exercise of this Option, for the same consideration, the same total number and
class of shares or other securities as [he/she] would have received had [he/she]
exercised this Option in full immediately prior to the event requiring the
adjustment; and (b) the number and class of shares reserved for issuance
pursuant to this Option shall be adjusted by substituting for the total number
and class of shares of stock then reserved that number and class of shares of
stock and other securities that would have been received by the holder of an
equal number of outstanding shares of stock as a result of the event requiring
the adjustment.

After a merger of one or more corporations or other entities into the Company,
or after a consolidation of the Company and one or more corporations or other
entities in which the Company shall be the surviving corporation, the Holder
shall, at no additional cost, be entitled upon exercise of this Option to
receive (subject to any required action by stockholders) in lieu of the Option
Shares, the number and class of shares of stock or other securities to which the
Holder would have been entitled pursuant to the terms of the agreement of merger
or consolidation if, immediately prior to such merger or consolidation, [he/she]
had been the holder of record of the Option Shares.

If the Company is merged into or consolidated with another corporation or entity
under circumstances in which the Company is not the surviving corporation, or if
the Company is liquidated, or sells or otherwise disposes of substantially all
of its assets to another corporation or entity while this Option is outstanding,
(i) subject to the provisions of clause (ii) below, after the effective date of
such merger, consolidation or sale, as the case may be, the Holder shall be
entitled, upon exercise of this Option, to receive, in lieu of the Option
Shares, shares of such stock or other securities as the holders of shares of
Stock received pursuant to the terms of the merger, consolidation or sale, or
(ii) this Option may be cancelled by the Committee as of the effective date of
any such merger, consolidation, liquidation or sale provided (x) notice of such
cancellation shall


                                       3

<PAGE>

be given to the Holder and (y) the Holder shall have the right to exercise this
Option in full as to the vested amount (including any amount which would
otherwise vest upon a change in control of the Company if the contemplated
transaction will cause a change in control and subject to such transaction being
consummated) during the 10-day period preceding the effective date of such
merger, consolidation, liquidation, sale or acquisition. The Committee may
provide any other alternative provided for in Section XI(c) of the Plan.

Except as hereinbefore expressly provided, the issuance by the Company of shares
of any class, or securities convertible into shares of stock of any class, for
cash or property, or for labor or services either upon direct sale or upon the
exercise of stock rights or warrants to subscribe therefor, or upon conversion
of shares or obligations of the Company convertible into such shares or other
securities, shall not affect, and no adjustment by reason thereof shall be made
with respect to, this Option.

and be exercisable in the following share amounts as of each indicated Service
Date. Service Date means the indicated date below (or in the Option
Certificate); provided, that on such date the Holder is a full-time employee or
director of the Company or an Affiliate (as defined in the Plan). This Option
shall terminate as to any amount not vested at the time such Holder's
involvement as a full-time employeeor director with the Company and Affiliates
is terminated, whether by dismissal, death, disability or otherwise. Vesting of
this Option as of the indicated Service Date is in accordance with the terms in
the Option Certificate for this Option.

provisions or restrictions in the Option Certificate for this Option.

7. Exercisability. This Option shall be exercisable only by the Holder while he
or she is an employee or directorof or to the Company (including a subsidiary or
affiliates) except that (A)(i) so long as the Option is otherwise exercisable,
it may be exercised by the personal representative of the deceased Holder within
12 months after the death of the Holder and (ii) if the Holder terminates his
employment and directorship with the Company (including its Affiliates), the
Holder may exercise any Option which is otherwise exercisable at any time within
three (3) months of such date of termination (within 12 months if termination is
the result of disability within the meaning of Section 22(e)(3) of the Code). If
the Holder should die during the applicable three month period following the
date of such Holder's termination, the rights of the personal representative of
the deceased Holder as such relate to the Options granted to the deceased Holder
shall be governed in accordance with clause (i) of the immediately preceding
sentence. Termination of employment means the Holder is no longer an employee,
director or consultant with or to the Company (including any subsidiary or
affiliate of the Company).

8. Notices of Record Date. In the event of (a) any taking by the Company of a
record of the holders of Stock for the purpose of determining the holders
thereof who are entitled to receive any dividend (other than a cash dividend
payable out of earned surplus of the Company) or other distribution, or any
right to subscribe for, purchase or otherwise acquire any shares of stock of any
class or any other securities or property, or to receive any other right, or (b)
any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any transfer of all or

merger of the Company with or into any other person, or (c) any voluntary or
involuntary dissolution, liquidation or winding-up of the Company, then and in
each such event the Company will use reasonable commercial efforts to send or
cause to be sent to the Holder a notice specifying (i) the date on which any
such record is to be taken for the purpose of such dividend, distribution or
right, and stating the amount and character of such dividend, distribution or
right, and (ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up is to take place, and the time, if any, as of which the holders of
record of Stock shall be entitled to exchange their shares of Stock for
securities or other property deliverable upon such reorganization,

dissolution, liquidation or winding-up. The Company shall use reasonable
commercial efforts to send such notice to the Holder at least 10 days prior to

any nature for failing to satisfy any obligation pursuant to this Section 8.

Option Shares and not fractions thereof unless the Company otherwise agrees.

representing fractions of Option Shares upon any exercise of this Option;

Option, the Holder may not exercise this Option, in whole or in part at such
times and from time to time as, in the reasonable opinion of counsel to the
Company, the issuance and sale to Holder of the Option Shares, upon exercise of
this Option, is not exempt from the registration provisions of the Act (unless
the Option and/or Option Shares, as applicable, have been registered under the
Act), or violates other applicable laws or regulations. The Company shall use
reasonable commercial efforts to cure such violation and/or potential violation
so as to permit exercise of this Option.

Agreement, the Option may be evidenced by an Option Certificate ("Option
Certificate") incorporating by reference the terms of this standard Option

or mutilation of any Option Agreement or Option Certificates evidencing
ownership of this Option and in the case of any such loss, theft or destruction
upon delivery of an indemnity agreement or, if the Holder so elects, a surety
bond reasonably satisfactory to the Company or, in the case of any such
mutilation, upon surrender and cancellation of any such Option Certificate, the
Company shall forthwith execute and deliver, in lieu thereof, a new Option

construed to confer upon the Holder of this Option, as such, any of the rights
of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to stockholders at any meeting thereof,
