(a) If the Escrow Agent receives at or prior to 11:00 a.m. (New York City time) prior to or on the Escrow End Date, a release certificate signed by an authorized officer of the Company in the form attached hereto as Exhibit A (the “Verizon Acquisition Release Certificate”), the Escrow Agent shall release to, or at the written direction of, the Company, the Net Offering Proceeds. Promptly upon consummation of the Verizon Acquisition, the Company shall deliver to the Escrow Agent a certificate signed by an authorized officer of the Company in the form attached hereto as Exhibit B (an “Verizon Acquisition Confirmation Certificate”) certifying that the Verizon Acquisition has been consummated.

(b) If (i) the Escrow Agent receives, at or prior to 11:00 a.m. (New York City time) prior to or on the Escrow End Date, a certificate signed by an authorized officer of the Company (a “Termination Certificate”), in the form attached hereto as Exhibit C, certifying that the Verizon Purchase Agreement has been terminated in accordance with its terms (the first Business Day on which the Escrow Agent has possession of the Termination Certificate, the “Termination Date”), (ii) the Escrow Agent has not received, at or prior to 11:00 a.m. (New York City time) on the Escrow End Date, a Verizon Acquisition Release Certificate, or (iii) the Escrow Agent has not received, at or prior to 11:59 p.m. (New York City time) on the Escrow End Date (such time on such date, the “Cut-Off Time”) a Verizon Acquisition Confirmation Certificate, the Escrow Agent shall promptly notify the Trustee in writing on the Termination Date (in the case of clause (i) of this sentence) or the Escrow End Date (in the case of clause (ii) or (iii) of this sentence) (the applicable date, the “Redemption Notice Date”) that Notes are to be redeemed on a specified date within the next two Business Days (or such other minimum period as may be required by the DTC) following the Redemption Notice Date (in all other cases) (the applicable date, the “Mandatory Redemption Date”) in accordance with the applicable provisions of the Indenture. The Trustee shall promptly notify each Holder (with a copy to the Escrow Agent) in accordance with the applicable provisions of the Indenture that all of the outstanding Notes shall be redeemed on the Mandatory Redemption Date automatically and without any further action by the Holder through the facilities of The Depository Trust Company.

(c) As soon as practicable after notice of redemption is given pursuant to Section 4(b), and in any case at or prior to 11:00 a.m. (New York City time) on the Escrow End Date, the Escrow Agent shall notify the Paying Agent, the Trustee and the Company of the amount of the Escrowed Funds on deposit in the Escrow Account as of the date such notice of redemption is received or the Escrow End Date, as applicable. The Company shall calculate the Mandatory Redemption Price and the Paying Agent shall notify the Escrow Agent, the Trustee and the Company if the amount of the Escrowed Funds is less than the Mandatory Redemption Price and the amount of such shortfall.

(d) In the event the Net Offering Proceeds have been released to the Company pursuant to Section 4(a) but for any reason the Verizon Acquisition is not consummated at or prior to the earlier of (i) the Cut-Off Time and (ii) 2:00 p.m. (New York City time) on the Business Day following such release of the Net Offering Proceeds, the Company shall promptly arrange for the redeposit of the Net Offering Proceeds into the Escrow Account, such redeposit in no event to be made later than 2:00 p.m. (New York City time) on the Mandatory Redemption Date. For the avoidance of doubt, a redeposit pursuant to this Section 4(d) shall not, in and of itself, be sufficient to require the Escrow Agent to disburse the Escrowed Funds pursuant to Section 4(b), and shall in no way limit the rights of the Company established in Section 4(a).

(e) Notwithstanding anything in this Escrow Agreement to the contrary, the Escrow Agent shall disburse Escrowed Funds as directed pursuant to a final judgment (without further right of appeal) of a court of competent jurisdiction; provided, however, that the Escrow Agent shall provide notice thereof to the Company prior to such disbursement.

(g) For the avoidance of doubt, the Company will pay the interest on the Notes due on the Interest Payment Dates (as defined in the Indenture) from its own funds and such payments will not come from the Escrow Account.

(h) The Escrow Agent shall make all disbursements hereunder in accordance with the payment instructions provided by the Company or, solely with respect to disbursements made pursuant to Section 4(b)(A), the Trustee, and shall have no duty to verify such payment instructions or to inquire as to their authenticity or the authority under which they were provided.

10.8 Interpretation of Agreement

10.18 Shareholder Communication Act, Etc.

With respect to securities issued in the United States, the Shareholders Communications Act of 1985 (the “Act”) requires Escrow Agent to disclose to the issuers, upon their request, the name, address and securities position of its Depositor who are (a) the “beneficial owners” (as defined in the Act) of the issuer’s securities, if the beneficial owner does not object to such disclosure, or (b) acting as a “respondent bank” (as defined in the Act) with respect to the securities. (Under the Act, “respondent banks” do not have the option of objecting to such disclosure upon the issuers’ request.) The Act defines a “beneficial owner” as any person who has, or shares, the power to vote a security (pursuant to an agreement or otherwise), or who directs the voting of a security. The Act defines a “respondent bank” as any bank, association or other entity that exercises fiduciary powers which holds securities on behalf of beneficial owners and deposits such securities for safekeeping with a bank, such as Escrow Agent. Under the Act, Depositor is either the “beneficial owner” or a “respondent bank.”

¨ Depositor is the “beneficial owner,” as defined in the Act, of the securities to be held by Escrow Agent hereunder.

¨ Depositor is not the beneficial owner of the securities to be held by Escrow Agent, but is acting as a “respondent bank,” as defined in the Act, with respect to the securities to be held by Escrow Agent hereunder.

IF NO BOX IS CHECKED, ESCROW AGENT SHALL ASSUME THAT THE COMPANY AS DEPOSITOR IS THE BENEFICIAL OWNER OF THE SECURITIES.

For beneficial owners of the securities only:

¨ Depositor objects

¨ Depositor does not object

to the disclosure of its name, address and securities position to any issuer which requests such information pursuant to the Act for the specific purpose of direct communications between such issuer and Depositor.

18

IF NO BOX IS CHECKED, ESCROW AGENT SHALL RELEASE SUCH INFORMATION UNTIL IT RECEIVES A CONTRARY WRITTEN INSTRUCTION FROM THE COMPANY AS DEPOSITOR.

With respect to securities issued outside of the United States, information shall be released to issuers only if required by law or regulation of the particular country in which the securities are located.

The Depositor agrees to disseminate in a timely manner any proxies or requests for voting instructions, other proxy soliciting material, information statements, and/or annual reports that it receives to any other beneficial owners.
