otherwise stated herein, the Original 13D as amended by Amendment No. 1 thereto
remains in full force and effect. Terms used herein and not defined herein shall
have the meanings ascribed thereto in the Original 13D as amended by Amendment

consummated on June 25, 2003. Pursuant to such Securities Purchase Agreement,
SPO Partners has agreed that it will not sell or otherwise dispose of any or all
of the shares of Common Stock of the Corporation purchased thereunder prior to
either (i) the date that BAM Inc. sells all of the shares of Common Stock of the
Corporation owned by it and included in a registration statement to be filed by
the Corporation with the Securities and Exchange Commission in the future, or

Shares that were sold to SPO Partners. Further, BAM Inc. and Verizon intend,
from time to time, to consider, engage in discussions regarding or consummate,
in one, or a series of, public or private sales transactions, the sale or other
disposition of all or a portion of the Contributed Shares then owned by BAM Inc.

-------------------                                                -------------

              subject to customary settlement procedures. Seller further
              covenants that it shall at any time, and from time to time after
              the date hereof, execute, acknowledge and deliver all further
              assignments, transfers, and any other such instruments of

3.       REPRESENTATIONS OF SELLER. Seller represents and warrants to Purchaser

         a)   Seller is the owner of record and beneficially owns and has the
              unrestricted right to transfer the Purchased Shares, free and
              clear of all liens, claims, charges, encumbrances and restrictions
              on transfer (other than as such right may be restricted by laws of
              general application, including the Securities Act of 1933, as
              amended (the "Act")).

         b)   Seller is a corporation duly organized, validly existing and in
              good standing under the laws of the State of Delaware and Seller
              has full right, power and authority to enter into this Agreement
              and to transfer the Purchased Shares and perform its obligations
              hereunder in accordance with the terms of this Agreement and has
              taken all necessary corporate action to authorize the execution,
              delivery and performance of this Agreement.

         c)   This Agreement has been duly authorized, executed and delivered by
              Seller and constitutes a legal, valid and binding obligation of
              Seller, enforceable in accordance with its terms (subject, as to
              enforceability, to applicable bankruptcy, insolvency,
              reorganization or other similar laws and to general principles of
              equity).

         d)   Seller's execution, delivery and performance of this Agreement do
              not violate or conflict with its certificate of incorporation or
              bylaws, any resolutions or directives of the board of directors of
              Seller, any law, rule or regulation applicable to Seller or its
              assets or properties, or any order or judgment of any

              court or other agency of government applicable to or affecting
              Seller or its assets or properties.

         e)   All of Seller's rights related to the Purchased Shares under the
              Rights Agreement are assignable to Purchaser. The Purchased Shares
              constitute "Registrable Securities" for purposes of the Rights
              Agreement. On the Closing Date, Seller agrees to assign and
              transfer all of its rights related to the Purchased Shares under
              the Rights Agreement to Purchaser, which rights shall thereafter
              inure to the benefit of Purchaser in accordance with the
              provisions of paragraph 4 of the Letter Agreement.

         f)   No consent, approval, authorization or order of, or filing or
              registration with, any court, regulatory authority or other
              governmental agency or body or third party is required in
              connection with the transactions contemplated herein.

         g)   Seller has not assigned or transferred any interest in any of the
              Purchased Shares, or entered into any agreement with the Company
              the effect of which is to modify the rights of the holder of the
              Purchased Shares as set forth herein.

         h)   Seller acknowledges and represents that it has made its own
              investigation into the merits and risks of entering into the
              transaction contemplated by this Agreement, and that it has the
              capacity and financial expertise to evaluate the same; and that it
              has adequate information concerning the business and financial
              condition of the Company to make an informed decision regarding
              the sale of the Purchased Shares and has not relied on any
              representations or warranties of Purchaser or its agents or
              affiliates (whether oral or written) other than the
              representations and warranties of Purchaser expressly provided
              herein.

         i)   Seller is not an "affiliate" of the Company, as such term is
              defined in Rule 144(a)(l) promulgated under the Act, nor is Seller
              selling the Purchased Shares on behalf of the Company or any
              affiliate thereof.

         j)   Seller is not currently acting as an agent of the Company, or as
              an underwriter or a dealer with respect to (or, participating in a
              distribution of) any securities of the Company.

         k)   Seller is not prompted to sell the Purchased Shares by any
              material, non-public information concerning the Company.

         l)   Neither Seller, nor any person acting on its behalf, has made or
              will make, directly or indirectly, any offers or sales with
              respect to any of the Purchased Shares by any form of general
              solicitation or general advertising (within the meaning of
              Regulation D under the Act).

         m)   Neither Seller, nor any person acting on its behalf, has made or
              will make, directly or indirectly, offers or sales of any
              security, or has solicited or will solicit offers to buy any
              security, under circumstances that would require the

              registration of the sale of the Purchased Shares from Seller to
              Purchaser under the Act.

4.       REPRESENTATIONS OF PURCHASER. Purchaser represents and warrants to
Seller that:

         a)   Purchaser is a limited partnership duly organized, validly
              existing and in good standing under the laws of Delaware and it
              has full right, power and authority to enter into this Agreement
              and to perform its obligations hereunder in accordance with the
              terms of this Agreement and has taken all necessary action to
              authorize the execution, delivery and performance of this
              Agreement.

         b)   This Agreement has been duly authorized, executed and delivered by
              it and constitutes a legal, valid and binding obligation of it,
              enforceable in accordance with its terms (subject, as to
              enforceability, to applicable bankruptcy, insolvency,
              reorganization or other similar laws and to general principles of
              equity).

         c)   Purchaser is acquiring the Purchased Shares to be acquired by it
              hereunder for its own account for investment purposes, and
              Purchaser will resell such Purchased Shares only in transactions
              which would be permissible under the securities laws of the United
              States of America or any state thereof.

         d)   Purchaser is an "accredited investor" as such term is defined in
              Rule 501(a) promulgated under the Act.

         e)   Purchaser represents that in the normal course of its business, it
              invests in or purchases securities similar to the Purchased Shares
              and that it has sufficient knowledge and experience in financial
              and business matters that it is capable of evaluating the merits
              and risks of purchasing the Purchased Shares.

         f)   Purchaser is aware that it may be required to bear the economic
              risk of an investment in the Purchased Shares for an indefinite
              period of time and it is able to bear the risk for an indefinite
              period.

         g)   Purchaser is aware that, until the Company is reasonably satisfied
              in accordance with industry practice that such legend is not
              required, a legend similar to the following may appear on the
              certificates representing the Purchased Shares: "These securities
              have not been registered under the Securities Act of 1933 and may
              be re-offered and sold only if so registered or if any exemption
              from registration is available."

         h)   Purchaser acknowledges and represents that it has made its own
              investigation into the merits and risks of entering into the
              transaction contemplated by this agreement and that it has the
              capacity and financial experience to evaluate the same. Purchaser
              has not relied on any statement, document or other information
              provided by or on behalf of Seller regarding the business,
              properties, prospects and financial condition of the Company.



-------------------                                                -------------

-------------------                                                -------------

         i)   Purchaser believes it has received all the information it
              considers necessary or appropriate for deciding whether to acquire
              the Purchased Shares and has had an opportunity to secure all such
              information as it deems necessary regarding the business,
              properties, prospects and financial condition of the Company.

         j)   Purchaser understands that the offer and the sale of the Purchased
              Shares are not being registered under the Act.

5.       REGISTRATION OF SHARES; LIMITATION ON RESALE. Seller hereby agrees to
instruct the Company to include Purchaser as a selling stockholder in the
Designated Registration Statement (as defined in the Rights Agreement) and to
include the Purchased Shares in the Designated Registration Statement to
register all such shares for sale in one or more public, private, negotiated and
other transactions from time to time; provided that Purchaser hereby agrees that
it shall not sell or otherwise dispose of any or all of the Purchased Shares
prior to either (i) the date that Seller sells all of the shares of Common Stock
owned by Seller and included for registration in the Designated Registration
Statement ("Seller's Registered Shares") or (ii) December 1, 2003, whichever is
earlier. Seller hereby agrees to advise Purchaser as to the date it expects to
complete its sales of the Seller's Registered Shares and shall notify Purchaser
that all Seller's Registrable Shares have been sold within one business day of
the closing of such sale or sales.

6.       LAW GOVERNING. This Agreement shall be governed by and constructed in
accordance with the laws of the State of New York without reference to choice of
law doctrine.

7.       PARTIES IN INTEREST. All the terms and provisions of this Agreement
shall be binding upon and inure to the benefit of and be enforceable by the
respective heirs, representatives, successors, and assigns of the parties
hereto.

8.       MISCELLANEOUS. This Agreement may be executed concurrently in
counterparts, each of which shall be deemed an original, but all of which

Ladies and Gentlemen:

                  Reference is hereby made to the Securities Purchase Agreement,
dated as of the date hereof (the "Purchase Agreement"), by and between Bell
Atlantic Mobile, Inc., a Delaware corporation ("Seller"), and SPO Partners II,
L.P., a Delaware limited partnership ("Purchaser"). Pursuant to, and in
accordance with the terms of, the Purchase Agreement, Purchase has sold to
Purchaser, and Purchaser has purchased from Seller, 4,900,000 shares of common
stock, par value $0.01 per share, of Crown Castle International Corp. (the
"Purchased Shares"). In connection with the sale and purchase of the Purchased
Shares, Seller has assigned and transferred to Purchaser, all of Seller's rights
related to the Purchased Shares under Exhibit 9.8 to the Formation Agreement
dated December 8, 1998, relating to the formation of Crown Atlantic Company LLC,
Crown Atlantic Holding Sub LLC and Crown Atlantic Holding Company LLC (the
"Rights Exhibit"), as amended by the letter agreement dated May 1, 2003 among
Seller, Crown Atlantic Holding Company LLC, CCA Investment Corp. and the Company
(the "Letter Agreement") (the Rights Exhibit, as amended by the Letter
Agreement, being referred to herein as the "Rights Agreement").

                  By execution of the acknowledgment below, the Company
acknowledges and agrees that the Purchased Shares are "Registrable Shares" for
purposes of the Rights Agreement and, as a result of the sale and purchase of
the Purchased Shares, the rights of Seller under the Rights Agreement shall
inure to the benefit of Purchaser in accordance with the provisions of paragraph
4 of the Letter Agreement. In addition, the Company acknowledges that the sales
limitations applicable to Seller under paragraph 10 of the Letter Agreement
shall not apply to sales by Purchaser and that the Company will use its best
efforts to cause the Designated Registration Statement (as defined in the Letter
Agreement) to become and remain effective until all Registrable Shares included
in such registration statement have been sold or until such Registrable Shares
are eligible for disposition pursuant to Rule 144 of the Securities Act, as
amended (so long as all of the Registrable Shares held by each holder included
in such registration statement may be sold during one calendar quarter pursuant
to such Rule 144).
