 CROWN CASTLE INTERNATIONAL CORP. 
The Corporation
will furnish to any stockholder, upon request and without charge, a full statement of the powers, designations, preferences and relative, participating, optional or other special rights of each class of stock or series thereof which the Corporation
is authorized to issue and the qualifications, limitations or restrictions of such preferences and rights of each class of stock or series thereof. Any such request should be made to the Secretary of the Corporation at its principal place of
business or to the Transfer Agent and Registrar. 
IMPORTANT NOTICE 
The shares
represented by this certificate are subject to restrictions on beneficial ownership (determined under the principles of Section 856(a)(5) of the Code), Beneficial Ownership and Constructive Ownership and Transfer for the purpose, among others,
of the Corporation’s maintenance of its status as a Real Estate Investment Trust under the Internal Revenue Code of 1986, as amended (the “Code”). Subject to certain further restrictions and except as expressly provided in the
Corporation’s Amended and Restated Certificate of Incorporation (“Charter”), (i) no Person may Beneficially Own or Constructively Own shares of the Corporation’s Common Stock in excess of the Common Stock Ownership Limit,
unless such Person is an Excepted Holder (in which case the Excepted Holder Limit shall be applicable); (ii) no Person may Beneficially Own or Constructively Own shares of Capital Stock of the Corporation in excess of the Aggregate Stock
Ownership Limit, unless such Person is an Excepted Holder (in which case the Excepted Holder Limit shall be applicable); (iii) no Person may Beneficially Own shares of Capital Stock that would result in the Corporation being “closely
held” under Section 856(h) of the Code; (iv) no Person may Beneficially or Constructively Own shares of Capital Stock that would otherwise cause the Corporation to fail to qualify as a REIT (including, but not limited to, Beneficial
Ownership or Constructive Ownership that would result in the Corporation owning (actually or Constructively) an interest in a tenant that is described in Section 856(d)(2)(B) of the Code if the income derived by the Corporation from such tenant
would cause the Corporation to fail to satisfy any of the gross income requirements of Section 856(c) of the Code); (v) no Person may Beneficially Own or Constructively Own shares of Capital Stock that could result in the Corporation
failing to qualify as a “domestically controlled qualified investment entity” under Section 897(h)(4)(B) of the Code; and (vi) no Person may Transfer shares of Capital Stock if such Transfer would result in the Capital Stock of
the Corporation being beneficially owned by fewer than 100 Persons (determined under the principles of Section 856(a)(5) of the Code). Any Person who Beneficially Owns or Constructively Owns or attempts or intends to Beneficially Own or
Constructively Own shares of Capital Stock which cause or will cause a Person to Beneficially Own or Constructively Own shares of Capital Stock in excess or in violation of the above limitations must immediately notify the Corporation. If any of the
restrictions on transfer or ownership provided in (i), (ii), (iii), (iv) or (v) above are violated, the shares of Capital Stock in excess or in violation of the above limitations will be automatically transferred to a Trustee of a Trust
for the benefit of one or more Charitable Beneficiaries. In addition, the Corporation may redeem shares if the Board of Directors determines that ownership or a Transfer may violate the restrictions described above. Furthermore, if the ownership
restriction provided in (vi) above would be violated, or upon the occurrence of certain events, attempted Transfers in violation of the restrictions described above may be void ab initio. All capitalized terms in this legend have the meanings
given to them in the Charter, as the same may be amended and/or restated from time to time, a copy of which, including the restrictions on transfer and ownership, will be furnished to each holder of shares of Capital Stock of the Corporation on
request and without charge. Requests for such a copy may be directed to the Secretary of the Corporation at its principal office.

The IRS requires that we report the cost basis of certain shares
acquired after January 1, 2011. If your shares were covered by the legislation and you have sold or transferred the shares and requested a specific cost basis calculation method, we have processed as requested. If you did not specify a cost
basis calculation method, we have defaulted to the first in, first out (FIFO) method. Please visit our website or consult your tax advisor if you need additional information about cost basis. If you do not keep in contact with us or do not have any
activity in your account for the time periods specified by state law, your property could become subject to state unclaimed property laws and transferred to the appropriate state.
