Depending upon his individual assessments of these factors from time to time, each Reporting Person may change his present intentions as stated above, including determining to acquire additional Shares or other securities of the Issuer (by means of open market or privately negotiated purchases) or to dispose of some or all of the Shares or other securities of the Issuer held by him or under his control.

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.

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).

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.

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.

-2-

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.

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.

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.

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.

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.

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

4. Representations of Purchaser. Purchaser represents and warrants to Seller that:

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.

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).

-3-

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.

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

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.

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.

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.”

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.

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.

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

-4-

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 together shall constitute one and the same instrument. Each counterpart may be delivered by facsimile transmission, which transmission shall be deemed delivery of an originally executed document. The headings of the Sections hereof are inserted for convenience only and shall not be deemed to constitute a part hereof. This Agreement constitutes the entire Agreement between the parties with respect to the subject matter hereof and supersedes all the previous agreements, promise or representations, whether written or oral, between the parties.

9. Fees and Expenses. Each of the Purchaser and Seller agrees to pay its own expenses and disbursements incident to the performance of its obligations hereunder.

EXHIBIT 9.8

REGISTRATION RIGHTS

SECTION 1. Certain Definitions.

(a) As used herein, the following terms shall have the following respective meanings:

“Commission” shall mean the U.S. Securities and Exchange Commission.

The terms “register,” “registered” and “registration” refer to a resale registration effected by preparing and filing a registration statement in compliance with the Securities Act, and the declaration or ordering of the effectiveness of such registration statement.

“Registrable Shares” shall mean those shares that are (a) (i) the Bidder Contributed Shares and (ii) any securities issued or issuable in respect of the Bidder Contributed Shares upon any stock split, stock dividend, distribution, reorganization, merger, consolidation, consideration, exchange, recapitalization or other similar event occurring following the date of the Agreement and (b) “restricted securities” as defined in rule 144(a)(3) under the Securities Act.

“Registration Expenses” shall mean all expenses, other than Selling Expenses, incurred by Bidder in complying with Sections 2, 3 and 4 hereof, including without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel and independent public accountants for Bidder, fees and expenses (including counsel fees) incurred in connection with complying with state securities or “blue sky” laws, fees of the National Association of Securities Dealers, Inc., transfer taxes, fees of transfer agents and registrars, costs of insurance and fees and disbursements of one counsel for the sellers of Registrable Shares.

“Selling Expenses” shall mean all underwriting discounts, selling commissions and stock transfer taxes applicable to the Registrable Securities registered pursuant to Sections 2, 3 and 4 hereof and the costs of any accountants, counsel or other experts retained by or on behalf of the holders of such Registrable Securities.

“Stockholders Agreement” shall mean the Stockholders Agreement dated as of the 21st of August, 1998 among Bidder and each of the Stockholders listed in Schedule I thereto.

(b) Capitalized terms used herein and not otherwise defined herein shall have the respective meanings set forth in Article 1 of the Formation Agreement dated as of December 8, 1998 (the “Agreement”), between Cellco Partnership, a Delaware general partnership doing business as Bell Atlantic Mobile (“BAM”), Crown Castle International Corp., a Delaware corporation (“Bidder”) and CCA Investment Corp., a wholly-owned, indirect subsidiary of Bidder, of which this Exhibit is a part.

SECTION 2. “Piggy-Back” Registration. If Bidder at any time proposes to register any of its securities under the Securities Act for sale to the public, whether for its own account or for the account of other security holders or both (except with respect to registration statements on Forms S-4, S-8 or any successor or similar forms thereto and other than pursuant to a registration under Section 3), each such time it will give written notice to all holders of outstanding Registrable Shares of its intention to do so. Upon the written request of any such holder, received by Bidder within twenty (20) days after the giving of any such notice by Bidder, to register any of its Registrable Shares, Bidder will, except as provided below, cause the Registrable Shares as to which registration shall have been so requested to be included in the securities to be covered by the registration statement proposed to be filed by the Bidder, all to the extent requisite to permit the sale or other disposition by the holder of such Registrable Shares so registered. In the event that any registration pursuant to this Section 2 shall be, in whole or in part, an underwritten public offering of securities, the number of securities to be included in such an underwriting may be reduced if and to the extent that the managing underwriter shall be of the opinion that such inclusion would adversely affect the marketing of the securities to be sold therein as follows: First, all persons (other than Bidder, the requesting holder of Registrable Shares and the requesting Stockholders) who have requested shares to be registered shall be reduced in the manner provided by Bidder. In the event that the number of shares requested to be registered after such reduction shall still be in excess of the number of shares recommended to be registered by the underwriters, then the number of shares shall be further reduced pro rata among the requesting holders of Registrable Shares according to the number of shares requested by each such holder to be registered. In the event the number of shares requested to be registered after such reduction shall still be in excess of the number of shares recommended to be registered by the underwriters than the number of shares shall be reduced among the requesting Stockholders in accordance with Article IV of the Stockholders Agreement. Notwithstanding the foregoing provisions, the Bidder may withdraw any registration statement referred to in this Section 2 without thereby incurring any liability to the holders of Registrable Shares. There shall be no limit to the number of registrations of Registrable Shares which may be effected under this Section 2.

SECTION 3. Demand Registration.

(a) The holders of at least half of the Registrable Shares at any time after the date of the Agreement and prior to the time Bidder is eligible to file a registration statement on Form S-3 or similar short-form registration, may request Bidder to register under the Securities Act all or a portion of the Registrable Shares held by them for sale in the manner specified in

such notice; provided that (i) the reasonably anticipated aggregate net proceeds to the sellers from such public offering would exceed $30,000,000 and (ii) subject to Section 3(c), no such request may be made more than once every nine months. Notwithstanding anything to the contrary herein, no request may be made under this Section 3 within 90 days after the effective date of a registration statement filed by Bidder covering a firm commitment underwritten public offering in which the holders of Registrable Shares shall have been entitled to join pursuant to Section 2 and in which there shall have been effectively registered all Registrable Shares as to which registration shall have been requested. Bidder shall be obligated to register the Registrable Shares pursuant to this Section 3(a) on two (2) occasions only; provided, however, that such obligations shall be deemed satisfied only when a registration statement covering all of the Registrable Shares specified in the notices received as aforesaid, for sale in accordance with the method of disposition specified by the requesting holders, shall have become effective and, if such method of disposition is a firm commitment underwritten public offering, all such shares shall have been sold pursuant thereto unless any such registration statement does not become effective due to the withdrawal of 66 2/3% of the Registrable Shares to be registered. Notwithstanding the foregoing, in the event Bidder is entitled to use Form S-3 or similar short-form registration but later is unable to do so, then to the extent the holders have not exercised their two demand rights under this Section 3(a), they shall be eligible to do so under this Section 3(a) until such time as Bidder again is entitled to use Form S-8 or similar short-form registration.

(b) Following receipt of any notice under this Section 3, Bidder shall immediately notify all holders of Registrable Shares from whom notice has not been received that a request for registration pursuant to Section 3(a) has been received and shall use its best efforts to register under the Securities Act, for public sale in accordance with the method of disposition specified in such notice from the requesting holders, the number of shares of Registrable Shares specified in such notice (and in all notices received by Bidder from other holders within twenty (20) days after the giving of such notice by Bidder). If such method of disposition shall be an underwritten public offering, the holders of a majority of the Registrable Shares to be sold in such offering may designate the managing underwriter of such offering, subject to the approval of Bidder, which approval shall not be unreasonably withheld or delayed.

(c) Bidder shall be entitled to include in any registration statement referred to in this Section 3, for sale in accordance with the method of disposition specified by the requesting holders, shares of Bidder’s securities to be sold by Bidder for its own account, and shares of any other person having registration rights with respect to the Bidder’s securities except as and to the extent that, in the opinion of the managing underwriter (if such method of disposition shall be an underwritten public offering), such inclusion would adversely affect the marketing of the Registrable Shares to be sold, then the number of shares to be registered and sold shall be reduced as follows: First, the shares of Bidder securities requested to be registered by shareholders with “piggyback” or other registration rights (other than the Stockholders and the holders of the Registrable Shares) shall be reduced at the direction of Bidder in accordance with the opinions of the underwriters participating in the public offering.

In the event that the elimination of all of such shares is not sufficient to reduce the number of shares of Bidder s securities to be registered to the number recommended by the underwriters, then the number of shares to be registered by Bidder shall then be reduced. In the event that the number of shares requested to be registered after such reduction shall still be in excess of the number of shares requested to be registered by the underwriters, then the number of shares of Registrable Shares shall be reduced pro rata according to the number of shares requested by each such holder to be registered. In the event the number of shares requested to be registered after such reduction shall still be in excess of the number of shares recommended to be registered by the underwriters, then the number of shares shall be reduced among the requesting Stockholders in accordance with Article IV of the Stockholders Agreement. In the event the number of shares requested to be registered by the holders of Registrable Shares under this Section 3 is reduced to any extent as a result of this Section 3(c), then (i) the holders of Registrable Shares shall not be deemed to have exercised a demand right pursuant to this Section 3, (ii) the holders of Registrable Shares shall be entitled to make another request to register all or a portion of the Registrable Shares at anytime after 30 days after the date of the initial request and (iii) Bidder shall use its reasonable best efforts to file a registration statement pursuant to a request made under (ii) above as promptly as possible. Except as provided in this Section 3 and except for registration statements on Forms S-4, S-8 or any successor or similar forms thereto and except for a registration statement being filed as a result of a request made pursuant to the foregoing sentence, Bidder will not file with the Commission any other registration statement with respect to its equity securities, whether for its own account or that of other stockholders, from the date of receipt of a notice from requesting holders pursuant to this Section 3 until ninety (90) days after the commencement of the public offering of the Registrable Shares covered by the registration statement requested pursuant to this Section 3.

(d) Notwithstanding anything to the contrary contained herein, no request may be made under this Section 3 within ninety (90) days after the effective date of a registration statement filed by Bidder covering a firm commitment underwritten public offering in which the holders of Registrable Shares shall have been entitled to join pursuant to Sections 2 and in which there shall have been effectively registered all of the Registrable Shares as to which registration shall have been requested.

SECTION 4. Registration on Form S-3.

(a) The holders of Registrable Shares may request at any time that Bidder file a registration statement on Form S-3 or any successor form thereto for a public offering of all or portion of the Registrable Shares provided that (a) the reasonably anticipated aggregate price to the public of the Registrable Shares to be offered would exceed $40,000,000 (or such lower amount in the case of a request by the holder to register the balance of the Registrable Shares), and (b) Bidder is a registrant entitled to use Form S-3 or any successor thereto to register such Registrable Shares. Promptly following receipt of any notice under this Section 4, Bidder shall use its best efforts to register under the Securities Act on Form S-3 or any successor form thereto, for public sale in accordance with the method of disposition specified in such notice, the number

of shares of Registrable Shares specified in such notice. Whenever Bidder is required by this Section 4 to use its best efforts to effect the registration of Registrable Shares, each of the procedures and requirements of Sections 3, 4 and 5 (including but not limited to the requirement that Bidder notify all holders of Registrable Shares from whom notice has not been received and provide them with the opportunity to participate in the offering) shall apply to such registration.

(b) Bidder shall be entitled to include in any registration statement referred to in this Section 4, for sale in accordance with the method of disposition specified by the requesting holders, shares of Bidder’s securities to be sold by Bidder for its own account, and shares of any other person having registration rights with respect to the Bidder’s securities except as and to the extent that, in the opinion of the managing underwriter (if such method of disposition shall be an underwritten public offering), such inclusion would adversely affect the marketing of the Registrable Shares to be sold, then the number of shares to be registered and sold shall be reduced as follows: First, the shares of Bidder securities requested to be registered by shareholders with “piggyback” or other registration rights (other than the Stockholders and the holders of the Registrable Shares) shall be reduced at the direction of Bidder in accordance with the opinions of the underwriters participating in the public offering. In the event that the elimination of all of such shares is not sufficient to reduce the number of shares of Bidder’s securities to be registered to the number recommended by the underwriters, then the number of shares to be registered by Bidder shall then be reduced. In the event that the number of shares requested to be registered after such reduction shall still be in excess of the number of shares requested to be registered by the underwriters, then the number of shares of Registrable Shares shall be reduced pro rata according to the number of shares requested by each such holder to be registered. In the event the number of shares requested to be registered after such reduction shall still be in excess of the number of shares recommended to be registered by the underwriters, then the number of shares shall be reduced among the requesting Stockholders in accordance with Article IV of the Stockholders Agreement. Except as provided in this Section 4 and except for registration statements on Forms S-4, S-8 or any successor or similar forms thereto, Bidder will not file with the Commission any other registration statement with respect to its equity securities, whether for its own account or that of other stockholders, from the date of receipt ala notice from requesting holders pursuant to this Section 4 until ninety (90) days after the commencement of the public offering of the Registrable Shares covered by the registration statement requested pursuant to this Section 4.

SECTION 5. Registration Procedures. If and whenever Bidder is required by the provisions of Sections 2, 3 or 4 to use its best efforts to effect the registration of any Registrable Shares under the Securities Act, Bidder will, as expeditiously as possible:

(a) prepare and file with the Commission a registration statement with respect to such securities, which in the case of Section 3 shall be on Form S-1 or other available form satisfactory to the holders with respect to such securities, and cause such registration statement to become and remain effective for the period specified in Section 5(i);

(b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for the period specified in paragraph (i) below and comply with the provisions of the Securities Act with respect to the disposition of all Registrable Shares covered by such registration statement in accordance with the sellers’ intended method of disposition set forth in such registration statement for such period;

(c) furnish to each seller of Registrable Shares and to each underwriter such number of copies of the registration statement and the prospectus included therein (including each preliminary prospectus) as such persons reasonably may request in order to facilitate the public sale or other disposition of the Registrable Shares covered by such registration statement;

(d) use its best efforts to register or qualify the Registrable Shares covered by such registration statement under the securities or “blue sky” laws of such jurisdictions as the sellers of Registrable Shares or, in the case of an underwritten public offering, the managing underwriter reasonably shall request; provided, however, that Bidder shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction;

(e) use its best efforts to list the Registrable Shares covered by such registration statement with any securities exchange or market on which the securities of Bidder, if applicable, is then listed or quoted;

(f) immediately notify each seller of Registrable Shares and each underwriter under such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event of which the Bidder has knowledge as a result of which the prospectus contained in such registration statement, as then in effect, contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing;

(g) at the request of any seller of Registrable Shares, use its best efforts to furnish on the date that Registrable Shares are delivered to the underwriters for sale pursuant to such registration: (i) an opinion dated such date of counsel representing Bidder for the purposes of such registration, addressed to the underwriters and to such seller, stating that such registration statement has become effective under the Securities Act and that (A) to the best knowledge of such counsel, no stop order suspending the effectiveness thereof has been issued and no proceedings for that purpose have been instituted or are pending or contemplated under the Securities Act, (B) the registration statement, the related prospectus and each amendment or supplement thereto comply as to form in all material respects with the requirements of the Securities Act (except that such counsel need not express any opinion as to financial statements contained therein) and (C) to such other effects as reasonably may be requested by counsel for

the underwriters or by such seller or its counsel and (ii) a letter dated such date from the independent public accountants retained by Bidder, addressed to the underwriters and to such seller, stating that they are independent public accountants within the meaning of the Securities Act and that, in the opinion of such accountants, the financial statements of Bidder included in the registration statement or the prospectus, or any amendment or supplement thereof, comply as to form in all material respects with the applicable accounting requirements of the Securities Act, and such letter shall additionally cover such other financial matters (including information as to the period ending no more than five (5) business days prior to the date of such letter) with respect to such registration as such underwriters reasonably may request;

(h) (i) make available for inspection by each seller of Registrable Shares, any underwriter participating in any distribution pursuant to such registration statement, and any attorney, accountant or other agent retained by such seller or underwriter, all financial and other records, pertinent corporate documents and properties of Bidder, (ii) cause Bidder’s officers, directors and employees to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement and (iii) provide each seller and its counsel with the opportunity to participate in the preparation of such registration statement;

(i) with respect to any registration statement pursuant to which Registrable Shares are to be sold pursuant to Sections 2, 3 or 4, Bidder shall use its best efforts to cause such registration statement to become and remain effective for one hundred and eighty (180) days; and

(j) enter into such agreements and take such other actions as the sellers of Registrable Shares and the underwriters reasonably request in order to expedite or facilitate the disposition of such Registrable Shares including, without limitation, preparing for and participating in, such number of “road shows” and all such other customary selling efforts as the underwriters reasonably request in order to expedite or facilitate such disposition. In connection with each registration hereunder, the sellers of Registrable Shares will furnish to Bidder in writing such information with respect to themselves and the proposed distribution by them as shall be reasonably necessary in order to assure compliance with Federal and applicable state securities laws. In connection with each registration pursuant to Sections 2, 3 or 4 coveting an underwritten public offering, Bidder and cash seller agree to enter into a written agreement with the managing underwriter selected in the manner herein provided in such form and containing such provisions as are customary in the securities business for such an arrangement between such underwriter and companies of Bidder’s size and investment stature (it being understood that Bidder will not require a selling stockholder to make any representation, warranty or agreement in such agreement other than with respect to such stockholder, the ownership of such stockholder’s securities being registered and such stockholder’s intended method of disposition). The representations and warranties by, and the other agreements on the part of, Bidder to and for the benefit of the underwriters in such written agreement with the underwriters shall also be made to and for the benefit of the selling stockholders. In the event that any condition to the obligations under any such written agreement with the underwriters is not met or waived, and

such failure to be met or waived is not attributable to the fault of the selling stockholders requesting a demand registration pursuant to Section 3, such request for registration shall not be deemed exercised for purposes of determining whether such registration has been effected for purposes of Section 3.

SECTION 6. Expenses. All Registration Expenses shall be borne by Bidder whether or not the registration statement has become effective. All Selling Expenses shall be borne by the participating sellers in proportion to the number of shares sold by each, or by such participating sellers other than Bidder (except to the extent Bidder shall be a seller) as they may agree.

SECTION 7. Indemnification and Contribution.

(a) In the event of a registration of any of the Registrable Shares under the Securities Act pursuant to Sections 2, 3 or 4, Bidder will indemnify and hold harmless each seller of such Registrable Shares thereunder, each underwriter of such Registrable Shares thereunder and each other person, if any, who controls such seller or underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such seller, underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Shares were registered under the Securities Act pursuant to Sections 2, 3 or 4, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each such seller, each such underwriter and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that Bidder will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished in writing by such seller, such underwriter or such controlling person specifically for use in such registration statement or prospectus.

(b) In the event of a registration of any of the Registrable Shares under the Securities Act pursuant to Sections 2, 3 or 4, each seller of such Registrable Shares thereunder, severally and not jointly, will indemnify and hold harmless Bidder, each person, if any, who controls Bidder within the meaning of the Securities Act, each officer of Bidder who signs the registration statement, each director of Bidder, each underwriter and each person who controls any underwriter within the meaning of the Securities Act, against all losses, claims, damages or liabilities, joint or several, to which Bidder or such officer, director underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement

under which such Registrable Shares were registered wider the Securities Act pursuant to Sections 2, 3 or 4, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse Bidder and each such officer, director, underwriter and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that such seller will be liable hereunder in any such case if and only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact made in reliance upon and in conformity with information pertaining to such seller, as such, furnished in writing to Bidder by such seller specifically for use in such registration statement or prospectus; and provided further, however, that the liability of each seller hereunder shall be limited to the proportion of any such loss, claim, damage, liability or expense which is equal to the proportion that the public offering price of the shares sold by such seller under such registration statement bears to the total public offering price of all securities sold thereunder, but not in any event to exceed the proceeds received by such seller from the sale of Registrable Shares covered by such registration statement.

(c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a clan in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof; but the omission so to notify the indemnifying party shall not relieve it front any liability which it may have to such indemnified party other than under this Section 7 and shall only relieve it from any liability which it may have to such indemnified party under this Section 7 if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 7 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably nay be deemed to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred.

(d) In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any indemnified party exercising rights under the Agreement, or any controlling person of any such holder, makes a claim for indemnification pursuant to this Section 7 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such ease notwithstanding the fact that this Section 7 provides for indemnification in such case, (ii) contribution under the Securities Act may be required on the part of any such selling holder or any such controlling person in circumstances for which indemnification is provided under this Section 7, or (iii) the indemnification provided for by this Section 7 is insufficient to hold harmless an indemnified party, other than by reason of the exceptions provided therein; then, and in each such case, Bidder and such holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) (x) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party on the other or (y) if the allocation provided by clause (x) above is not permitted by applicable law, or provides a lesser sum to the indemnified party than the amount hereinafter calculated, in such proportion as is appropriate to reflect not only the relative fault referred to in clause (x) above but also the relative benefits received by the indemnifying party and the indemnified party from the offering of the securities (taking into account the portion of the proceeds of the offering received by each such party) as well as the statements or omissions which resulted in such losses, claims, damages or liabilities and any other relevant equitable considerations.

Re:	Redemption Agreement dated as of May 1, 2003 between Crown Atlantic Holding Company LLC and Bell Atlantic Mobile, Inc.

Gentlemen/Ladies:

Pursuant to the Formation Agreement dated December 8, 1998, as amended (the “Formation Agreement”), relating to the formation of Crown Atlantic Company LLC, Crown Atlantic Holding Sub LLC and Crown Atlantic Holding Company LLC, Crown Castle International Corp., a Delaware corporation (“Bidder”) granted to Cellco Partnership, a Delaware general partnership (“Cellco”), and Cellco’s successors and assigns, certain registration rights set forth in Exhibit 9.8 to the Formation Agreement. Pursuant to the provisions of the Redemption Agreement dated May 1, 2003 (the “Redemption Agreement”) between Crown Atlantic Holding Company LLC, a Delaware limited liability company (the “Company”), and Bell Atlantic Mobile, Inc., a Delaware corporation (“BAM”), the Company agreed to redeem on the terms specified therein the Percentage Interest and Membership Interest in the Company held by BAM in consideration of the transfer to BAM by the Company of the CCIC Shares (which include the Bidder Contributed Shares). All capitalized terms that are used in this letter agreement but not defined herein shall have the respective meanings given to them in the Redemption Agreement and, if not defined therein, shall have the respective meanings given to them in the Formation Agreement, including Exhibit 9.8 thereto.

This letter agreement is written to amend the obligations of Bidder to register under the Securities Act the Registrable Shares, including (without limitation) the CCIC Shares, which will be held by BAM upon consummation of the transactions contemplated by the Redemption Agreement.

In this regard, by executing this letter agreement in the appropriate spaces provided below, (i) each of the Company and Bidder shall hereby acknowledge its agreement with the terms of this

Crown Atlantic Holding Company LLC
CCA Investment Corp.
Crown Castle International Corp.
c/o Crown Castle International Corp.

letter agreement, (ii) Bidder Member shall hereby acknowledge its consent to the matters contemplated by this letter agreement and (iii) Bidder shall further hereby acknowledge its agreement to perform its obligations under Exhibit 9.8 to the Formation Agreement as such obligations may be amended by the terms of this letter agreement, each of the foregoing as follows:

As modified by this letter agreement, the provisions of the Formation Agreement, including (without limitation) Exhibit 9.8 thereto, are and shall remain in full force and effect. Accordingly, except as stated herein, this letter agreement shall have no effect on the registration rights and obligations of the applicable parties set forth in Exhibit 9.8 to the Formation Agreement.

As the successor in interest to Cellco in respect of the Redeemed Interest, BAM shall accede to all rights and benefits conferred upon Cellco under Exhibit 9.8 to the Formation Agreement (as modified by this letter agreement) in respect of the CCIC Shares assigned and transferred to BAM by the Company pursuant to the Redemption Agreement in consideration of the Redeemed Interest.

3.	The term “Registrable Shares” shall include the CCIC Shares (which include the Bidder Contributed Shares).

Upon consummation of the transactions contemplated by the Redemption Agreement, there will be no holders of Registrable Shares other than BAM. BAM shall have the right to transfer all or part of the CCIC Shares (which include the Bidder Contributed Shares) to one or more of its affiliates. In addition, each holder of Registrable Shares shall have the right to sell or otherwise transfer to one or more non-affiliated Persons all or a portion of such holder’s Registrable Shares in one or more transactions at any time and from time to time. The rights of BAM under Exhibit 9.8 to the Formation Agreement shall inure to the benefit of each transferee (including, without limitation, transferees that are and are not affiliates of BAM) that is the holder, and each group of transferees (comprised of any mix of BAM, transferees that are affiliates of BAM, and transferees that are not affiliates of BAM) that collectively are the holders, of 2,000,000 or more Registrable Shares. Further, the rights of BAM under Exhibit 9.8 to the Formation Agreement shall inure to the benefit of each transferee that is an affiliate of BAM that is the holder of less than 2,000,000 Registrable Shares provided that, in exercising any such rights or availing itself of the benefit of any such rights, such transferee shall be obligated to include the balance of the Registrable Shares held by such transferee.

5.	Section 3(a) of Exhibit 9.8 to the Formation Agreement is hereby revised and restated in its entirety as follows:

The holders of at least half of the Registrable Shares at any time after the date of the Agreement and prior to the time Bidder is eligible to file a registration

statement on Form S-3 or similar short-form registration, may request Bidder to register under the Securities Act all or a portion of the Registrable Shares held by them for sale in the manner specified in such notice, provided that, subject to Section 3(c), no such request may be may made more than once every nine months. Notwithstanding anything to the contrary herein, no request may be made under this Section 3 within 90 days after the effective date of a registration statement filed by Bidder covering a firm commitment underwritten public offering in which the holders of Registrable Shares shall have been entitled to join pursuant to Section 2 and in which there shall have been effectively registered all Registrable Shares as to which registration shall have been requested. Notwithstanding the foregoing, in the event Bidder is entitled to use Form S-3 or similar short-form registration but later is unable to do so, then the holders shall be eligible to exercise their demand rights under this Section 3(a) until such time as Bidder is again entitled to use Form S-3 or similar short-form registration.

Bidder and the Company hereby represent and warrant to BAM as of the date of this letter agreement that (a) Bidder meets the eligibility requirements for the use of Form S-3 set forth in General Instruction I.A. to Form S-3 under the Securities Act and (b) registration under the Securities Act of the sale of the Registrable Securities by the holders thereof meets the transaction requirements for the use of Form S-3 set forth in General Instruction I.B.3. to Form S-3 under the Securities Act. Bidder and the Company hereby represent and warrant to BAM that as of the date of this letter agreement neither Bidder nor the Company is aware of any reason why the representations and warranties in the preceding sentence will not continue to be true as of the dates that Bidder files the Designated Registration Statement (defined below) with the SEC and the Designated Registration Statement becomes effective.

7.	Section 4(a) of Exhibit 9.8 to the Formation Agreement is hereby revised and restated in its entirety as follows:

The holders of Registrable Shares may request at any time that Bidder file a registration statement on Form S-3 or any successor form thereto for a public offering of all or a portion of the Registrable Shares, provided that Bidder is a registrant entitled to use Form S-3 or any successor thereto to register such Registrable Shares. Promptly following receipt of any notice under this Section 4, Bidder shall use its best efforts to register under the Securities Act on Form S-3 or any successor form thereto, for public sale in accordance with the method of disposition specified in such notice, the number of shares of Registrable Shares specified in such notice. Whenever Bidder is required by this Section 4 to use its best efforts to effect the registration of Registrable Shares, each of the procedures and requirements of Sections 4 and 5 shall apply to such registration.

8.	Section 4(b) of Exhibit 9.8 to the Formation Agreement is hereby revised and restated in its entirety as follows:

Crown Atlantic Holding Company LLC

Page 4

Bidder shall be entitled to include in any registration statement referred to in this Section 4, for sale in accordance with the method of disposition specified by the requesting holders, shares of Bidder’s securities to be sold by any person (other than Bidder) having registration rights with respect to Bidder’s securities entitling such person as of the date of this letter agreement to have its shares of Bidder’s securities so registered, except as and to the extent that, in the opinion of the managing underwriter (if such method of disposition shall be an underwritten public offering), such inclusion would adversely affect the marketing of the Registrable Shares to be sold, in which case, the number of shares to be sold shall be reduced as follows: First, the shares of Bidder’s securities requested to be registered by shareholders with “piggyback” or similar registration rights entitling such shareholders, prior to the date of this letter agreement, to have their shares of Bidder’s securities so registered (other than any holder of Registrable Shares making demand for its shares of Bidder’s securities to be so included in such registration statement) shall be reduced at the direction of Bidder in accordance with the opinions of the underwriters participating in the public offering. In the event the number of shares requested to be registered after such reduction shall still be in excess of the number of shares recommended to be registered by the underwriters, then the number of shares shall be reduced among the requesting Stockholders (if and only to the extent that such Stockholders have the right to make such request on the date of this letter agreement) in accordance with Article IV of the Stockholders Agreement. In the event that the number of shares requested to be registered after such reduction shall still be in excess of the number of shares requested to be registered by the underwriters, then the number of shares of Registrable Shares shall be reduced pro rata according to the number of shares requested by each such holder to be registered.

The language contained in Section 5(i) of Exhibit 9.8 to the Formation Agreement that states, “for one hundred and eighty (180) days,” is hereby deleted and replaced in its entirety with “until all Registrable Shares included in such registration statement have been sold in one or more of transactions of the type contemplated by such registration statement, provided, the requirement shall terminate upon the Registrable Shares becoming eligible for disposition pursuant to Rule 144 of the Securities Act of 1933, as amended, so long as all of the Registrable Shares held by each holder may be sold during one calendar quarter pursuant to such Rule 144.”

10.

BAM agrees to limit its sales of Registrable Shares pursuant to an effective registration statement to 300,000 shares (subject to adjustment below) on any trading day, plus for such trading day any additional Registrable Shares sold by BAM in one or more privately negotiated or other transactions not involving the sale thereof by BAM in the open market; provided that the aforementioned 300,000-share limitation shall be increased ratably from time to time (a) upon any stock split, stock dividend (other than stock dividends relating to

existing preferred shares), distribution, reorganization, merger, consolidation, consideration, exchange, recapitalization or other similar event occurring following the date of this letter agreement and (b) upon any subsequent issuance of shares of common stock of Bidder.

Notwithstanding the above, the 300,000 share per trading day limitation shall increase as follows:

(i) to 400,000 shares per day if the Designated Registration Statement is declared effective after August 1, 2003;

(ii) to 500,000 shares per day if the Designated Registration Statement is declared effective after September 1, 2003; and

(iii) to an unlimited number if the Designated Registration Statement is declared effective after September 15, 2003.

11.

In addition to the foregoing, this letter shall serve as a request by BAM, as a holder of Registrable Shares, in accordance with Section 4 of Exhibit 9.8 to the Formation Agreement that Bidder file a registration statement (the “Designated Registration Statement”) on Form S-3 to register for sale in one or more public, private, negotiated and other transactions from time to time all of the Registrable Shares held by BAM upon the consummation of the transactions contemplated by the Redemption Agreement. Additional information contemplated by such Section 4 shall be provided to Bidder under separate cover. Bidder hereby agrees that it shall prepare and file the Designated Registration Statement with the SEC as soon as practicable but in no event later than July 1, 2003.

12.

Anything to the contrary notwithstanding, nothing herein or in the Formation Agreement, including (without limitation) Exhibit 9.8 thereto, shall be deemed to limit or restrict in any manner any other rights or remedies that any party may have against any other party at law, in equity or otherwise, in connection with the failure of the other party to perform its obligations under this Agreement or to observe the provisions of this Agreement. No such right or remedy pursued by a party is intended to be exclusive of any other such right or remedy, and each and every such right and remedy available to a party shall be cumulative and shall be in addition to such other rights and remedies available to such party.

13.

Each of Bidder and the Company hereby represents and warrants to BAM, and BAM hereby represents to Bidder and the Company, that this letter agreement has been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, except as such enforceability may be limited by the effects of bankruptcy, insolvency, fraudulent conveyance and similar laws affecting the rights and remedies of creditors generally and general principles of equity.
