(b)                                  Exchange Procedures for the SoftBank US Mergers .  On the Closing Date, promptly following the SoftBank US Mergers Effective Time, SoftBank shall cause the certificates (each, a “ SoftBank Certificate ”) and book-entry shares (each, a “ SoftBank Book-Entry Share ”) that immediately prior to the SoftBank US Mergers Effective Time represented outstanding shares of Starburst Common Stock and Galaxy Common Stock (or affidavits of loss in lieu of SoftBank Certificates pursuant to Section 3.5(j) ) to be surrendered to the Exchange Agent, and upon such surrender, the holder of such SoftBank Certificates and such SoftBank Book-Entry Shares shall be entitled to receive, in exchange therefor, that number of whole shares of T-Mobile Common Stock (which shall be in book-entry form) that such holder has the right to receive pursuant to the provisions of this Article III , and such SoftBank Certificates and SoftBank Book-Entry Shares so surrendered shall forthwith be canceled.  Until surrendered as contemplated by this Section 3.5 , each SoftBank Certificate or SoftBank Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the applicable pro rata portion of the Galaxy Merger Consideration or the applicable pro rata portion of the Starburst Merger Consideration, as applicable.  No interest shall be paid or shall accrue for the benefit of holders of SoftBank Certificates or SoftBank Book-Entry Shares on the Galaxy Merger Consideration or the Starburst Merger Consideration payable upon the surrender of SoftBank Certificates or SoftBank Book-Entry Shares.

(c)                                   Exchange Procedures for the Merger .  As soon as reasonably practicable after the Effective Time (and in any event within five (5) business days thereafter), the Exchange Agent shall mail to each holder of record of a certificate (a “ Certificate ”) that immediately prior to the Effective Time represented outstanding shares of Sprint Common Stock and whose shares were converted into the right to receive the Merger Consideration, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates (or affidavits of loss in lieu of Certificates pursuant to Section 3.5(j) ) to the Exchange Agent, and which shall be in a form reasonably acceptable to T-Mobile and Sprint) and (ii) instructions for use in effecting the surrender of the Certificates (or affidavits of loss in lieu of Certificates pursuant to Section 3.5(j) ) in exchange for the Merger Consideration.  Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by T-Mobile, together with such letter of transmittal, duly executed, or, in the case of a book-entry share (a “ Book-Entry Share ”) that immediately prior to the Effective Time represented outstanding shares of Sprint Common Stock and whose shares were converted into the right to receive the Merger Consideration, upon the surrender of such Book-Entry Share, and in each case upon delivery of such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor that number of whole shares of T-Mobile Common Stock (which shall be in book-entry form) and, if any, cash in lieu of fractional

11

shares as set forth in Section 3.5(f)  that such holder has the right to receive pursuant to the provisions of this Article III , and the Certificate or Book-Entry Share so surrendered shall forthwith be canceled.  If any portion of the Merger Consideration is to be registered in the name of a person other than the person in whose name the applicable surrendered Certificate or Book-Entry Share is registered, it shall be a condition to the registration of such Merger Consideration that the surrendered Certificate or Book-Entry Share shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any transfer or other taxes required by reason of such registration in the name of a person other than the registered holder of such Certificate or Book-Entry Share or establish to the reasonable satisfaction of the Exchange Agent that such tax has been paid or is not applicable.  Until surrendered as contemplated by this Section 3.5 , each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration.  No interest shall be paid or shall accrue for the benefit of holders of Certificates or Book-Entry Shares on the Merger Consideration payable upon the surrender of Certificates or Book-Entry Shares.

(d)                                  Distributions with Respect to Unexchanged Shares .  No dividends or other distributions with respect to T-Mobile Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate, SoftBank Certificate, Book-Entry Share or SoftBank Book-Entry Share with respect to any shares of T-Mobile Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 3.5(f) , in each case until the later of the surrender of such Certificate, SoftBank Certificate, Book-Entry Share or SoftBank Book-Entry Share in accordance with this Article III and the payment date for such dividends or distributions.

(e)                                   No Further Ownership Rights in Sprint Common Stock .  The Merger Consideration, the Galaxy Merger Consideration and the Starburst Merger Consideration paid upon the surrender for exchange of Certificates, SoftBank Certificates, Book-Entry Shares or SoftBank Book-Entry Shares in accordance with the terms of this Article III shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Sprint Common Stock theretofore represented by such Certificates, SoftBank Certificates, Book-Entry Shares or SoftBank Book-Entry Shares, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Sprint Common Stock that were outstanding immediately prior to the Effective Time.  If, after the Effective Time, Certificates, SoftBank Certificates, Book-Entry Shares or SoftBank Book-Entry Shares are presented to T-Mobile, the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article III .

(f)                                    Fractional Shares .

(i)                                      No certificates or scrip or book-entry notations representing fractional shares of T-Mobile Common Stock shall be issued upon the surrender for exchange of Certificates, SoftBank Certificates, Book-Entry Shares or SoftBank Book-Entry Shares, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of T-Mobile.

12

(ii)                                   Notwithstanding any other provision of this Agreement, each holder of shares of Sprint Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of T-Mobile Common Stock (after taking into account all Certificates and Book-Entry Shares delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount as determined below.  As promptly as practicable following the Effective Time, the Exchange Agent shall determine the excess of (A) the aggregate number of shares of T-Mobile Common Stock delivered to the Exchange Agent by T-Mobile for issuance to holders of Certificates or Book-Entry Shares over (B) the aggregate number of whole shares of T-Mobile Common Stock to be distributed to holders of Certificates or Book-Entry Shares (such excess being herein referred to as the “ Excess Shares ”).  As soon as practicable after the Effective Time, the Exchange Agent, as agent for such holders of Certificates or Book-Entry Shares, shall sell the Excess Shares at then prevailing prices on NASDAQ, all in the manner provided herein.

(iii)                                The sale of the Excess Shares by the Exchange Agent on NASDAQ shall be executed in round lots to the extent practicable.  Until the net proceeds of any such sale or sales have been distributed to the holders of Certificates or Book-Entry Shares, the Exchange Agent shall hold such proceeds in trust for such holders.  The net proceeds of any such sale or sales of Excess Shares to be distributed to the holders of Certificates or Book-Entry Shares shall be reduced by any and all commissions, transfer taxes and other out-of-pocket transaction costs, as well as any expenses, of the Exchange Agent incurred in connection with such sale or sales.  The Exchange Agent shall determine the portion of such net proceeds to which each holder of Certificates or Book-Entry Shares shall be entitled, if any, by multiplying the amount of the aggregate net proceeds by a fraction, the numerator of which is the amount of the fractional share interest to which such holder of Certificates or Book-Entry Shares is entitled (after taking into account all Certificates and Book-Entry Shares of such holder) and the denominator of which is the aggregate amount of fractional share interests to which all holders of Certificates or Book-Entry Shares are entitled.  As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Certificates or Book-Entry Shares with respect to any fractional share interests, the Exchange Agent shall promptly pay such amounts to such holders subject to and in accordance with this Section 3.5(f) .

(g)                                   Return of Merger Consideration .  Any portion of the Merger Consideration made available to the Exchange Agent that remains undistributed to the holders of Certificates or Book-Entry Shares for one year after the Effective Time shall be delivered to T-Mobile, upon demand, and any holders of Certificates or Book-Entry Shares who have not theretofore complied with this Article III shall thereafter be entitled to look only to T-Mobile for payment of their claim for the Merger Consideration payable in respect of such shares and any dividends or distributions with respect to T-Mobile Common Stock.

(h)                                  No Liability .  None of Sprint, T-Mobile, Merger Sub, Merger Company, the Surviving Corporation, the SoftBank Surviving Entity, the DT Parties, the SoftBank Parties or the Exchange Agent shall be liable to any person in respect of any portion of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property,

13

escheat or similar law.  If any Certificate or Book-Entry Share has not been surrendered prior to seven years after the Effective Time, or immediately prior to such earlier date on which any cash, any shares of T-Mobile Common Stock, any cash in lieu of fractional shares of T-Mobile Common Stock or any dividends or distributions with respect to T-Mobile Common Stock in respect of such Certificate or Book-Entry Share would otherwise escheat to or become the property of any Governmental Entity, any such shares, cash or dividends or distributions in respect of such Certificate or Book-Entry Share shall, to the extent permitted by applicable Law, become the property of T-Mobile, free and clear of all claims or interests of any person previously entitled thereto.

(i)                                      Withholding Rights .  Each of T-Mobile and the Exchange Agent shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement (including any shares of T-Mobile Common Stock otherwise required to be delivered pursuant to this Article III ) such amounts as it is required to deduct and withhold with respect to the making of such payment (or delivery) under the Code or any provision of state, local or foreign Tax Law.  To the extent that amounts are so withheld or paid over to or deposited with the relevant Taxing Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made.

(j)                                     Lost, Stolen or Destroyed Certificates .  If any Certificate or SoftBank Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate or SoftBank Certificate to be lost, stolen or destroyed and, if required by T-Mobile or the Exchange Agent, the posting by such person of a bond in such reasonable amount as T-Mobile or the Exchange Agent, as applicable, may direct as indemnity against any claim that may be made against it with respect to such Certificate or SoftBank Certificate, as applicable, the Exchange Agent shall deliver (i) in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration with respect to the shares of Sprint Common Stock formerly represented thereby, any cash in lieu of fractional shares of T-Mobile Common Stock, and any unpaid dividends and distributions on shares of T-Mobile Common Stock deliverable in respect thereof, pursuant to this Agreement and (ii) in exchange for such lost, stolen or destroyed SoftBank Certificate, the applicable pro rata portion of the Galaxy Merger Consideration or the applicable pro rata portion of the Starburst Merger Consideration, as applicable, with respect to the shares of Galaxy Common Stock or Starburst Common Stock formerly represented thereby and any unpaid dividends and distributions on shares of T-Mobile Common Stock deliverable in respect thereof, pursuant to this Agreement.

Section 3.6.                                  Certain Adjustments .  If, between the date of this Agreement and the Effective Time, the outstanding shares of Sprint Common Stock or T-Mobile Common Stock are changed into a different number of shares by reason of any reclassification, recapitalization, split-up, combination, exchange of shares, dividend payable in stock or other securities or other similar transaction, the Exchange Ratio and related provisions shall be appropriately adjusted to provide to the holders of Sprint Common Stock, Galaxy Common Stock, Starburst Common Stock or Sprint Equity Awards the same economic effect as contemplated by this Agreement prior to such reclassification, recapitalization, split-up, combination, exchange, dividend or other similar transaction.  Nothing in this Section 3.6  shall be construed to permit any party to take any action that is otherwise prohibited or restricted by any other provision of this Agreement.
