Item 1.01 Entry Into a Material Definitive Agreement.

Business Combination Agreement

On April 29, 2018, T-Mobile US, Inc. (“T-Mobile”) entered into a Business Combination Agreement (the “Business Combination Agreement”) with Sprint Corporation, a Delaware corporation (“Sprint”), Huron Merger Sub LLC, a Delaware limited liability company and a wholly owned subsidiary of T-Mobile (“T-Mobile Merger Company”), Superior Merger Sub Corporation, a Delaware corporation and a wholly owned subsidiary of T-Mobile Merger Company (“Merger Sub”), Starburst I, Inc., a Delaware corporation (“Starburst”), Galaxy Investment Holdings, Inc., a Delaware corporation (“Galaxy,” and together with Starburst, the “SoftBank US HoldCos”), and for the limited purposes set forth therein, Deutsche Telekom AG, an Aktiengesellschaft organized and existing under the laws of the Federal Republic of Germany (“Deutsche Telekom”), Deutsche Telekom Holding B.V., a besloten vennootschap met beperkte aansprakelijkheid organized and existing under the laws of the Netherlands (“DT Holding”), and SoftBank Group Corp., a Japanese kabushiki kaisha (“SoftBank”).

Pursuant to the Business Combination Agreement and upon the terms and subject to the conditions described therein, the SoftBank US HoldCos will merge with and into T-Mobile Merger Company, with T-Mobile Merger Company continuing as the surviving entity and as a wholly owned subsidiary of T-Mobile (the “HoldCo Mergers”).  Immediately following the HoldCo Mergers, Merger Sub will merge with and into Sprint, with Sprint continuing as the surviving corporation and as a wholly owned indirect subsidiary of T-Mobile (the “Merger” and, together with the HoldCo Mergers, the “Merger Transactions”).  Pursuant to the Business Combination Agreement, (i) at the effective time of the HoldCo Mergers, all the issued and outstanding shares of common stock of Galaxy, par value $0.01 per share, and all the issued and outstanding shares of common stock of Starburst, par value $0.01 per share, held by SoftBank Group Capital Limited, a private limited company incorporated in England and Wales and a wholly owned subsidiary of SoftBank and the sole stockholder of Galaxy and Starburst (“SoftBank UK”), will be converted such that SoftBank UK will receive an aggregate number of shares of common stock of T-Mobile, par value $0.00001 per share (the “T-Mobile Common Stock”), equal to the product of (x) 0.10256 (the “Exchange Ratio”) and (y) the aggregate number of shares of common stock of Sprint, par value $0.01 per share (“Sprint Common Stock”), held by the SoftBank US HoldCos, collectively, immediately prior to the effective time of the HoldCo Mergers, and (ii) at the effective time of the Merger, each share of Sprint Common Stock issued and outstanding immediately prior to the effective time of the Merger (other than shares of Sprint Common Stock that were held by the SoftBank US HoldCos or are held by Sprint as treasury stock) will be converted into the right to receive a number of shares of T-Mobile Common Stock equal to the Exchange Ratio.  SoftBank and its affiliates will receive the same amount of T-Mobile Common Stock per share of Sprint Common Stock as all other Sprint stockholders.

Immediately following the Merger Transactions, Deutsche Telekom and SoftBank are expected to hold approximately 42% and 27% of the fully diluted shares of T-Mobile Common Stock, respectively, with the remaining approximately 31% of the fully diluted shares of T-Mobile Common Stock held by public stockholders.

Pursuant to the Business Combination Agreement and upon the terms and subject to the conditions described therein, in connection with the Merger, each option to purchase Sprint Common Stock (other than under the Sprint Employees Stock Purchase Plan) will be converted into an option to purchase T-Mobile Common Stock; each time-based restricted stock unit award covering Sprint Common Stock will be converted into a time-based restricted stock unit award covering T-Mobile Common Stock; with respect to each performance stock unit award covering Sprint Common Stock (a “PSU Award”) for which performance is measured using the volume-weighted average price of Sprint Common Stock (the “VWAP”), for the portion of such PSU Award subject to performance-based vesting, the VWAP will be deemed equal to the greatest of (x) the VWAP over the five (5) consecutive trading day period ending with the second complete trading day prior to the effective time of the Merger, (y) the VWAP over any 150 calendar day period as specified in the applicable award agreement as of the effective time of the Merger, and (z) the VWAP corresponding to “target” level performance for such PSU Award, and the entire portion of such PSU Award will be converted into a time-based restricted stock unit award covering T-Mobile Common Stock; with respect to each PSU Award for which performance is not measured using the VWAP, for the portion of any such PSU Award subject to performance-based vesting, performance will be deemed met at “target” levels, and the entire portion of such PSU Award will be converted into a time-based restricted stock unit award covering T-Mobile Common Stock; and the purchase period underway under the Sprint Employees Stock Purchase Plan will terminate and each outstanding purchase right thereunder will be exercised.

The consummation of the Merger Transactions and the other transactions contemplated by the Business Combination Agreement (collectively, the “Transactions”) is subject to obtaining the consent of the holders of a majority of the outstanding shares of Sprint Common Stock in favor of the adoption of the Business Combination Agreement (the “Sprint Stockholder Approval”).  Subsequent to the execution of the Business Combination Agreement, SoftBank entered into a support agreement (the “SoftBank Support Agreement”), pursuant to which it has agreed to cause SoftBank UK, Galaxy and Starburst to deliver a written consent in favor of the adoption of the Business Combination Agreement, which will constitute receipt by Sprint of the Sprint Stockholder Approval.  As of April 25, 2018, SoftBank beneficially owned approximately 84.8% of Sprint Common

2

Stock outstanding.  Under the terms of the SoftBank Support Agreement, SoftBank and its affiliates are generally prohibited from transferring ownership of Sprint Common Stock prior to the earlier of the consummation of the Merger and the termination of the Business Combination Agreement in accordance with its terms.  The consummation of the Transactions is also subject to obtaining the consent of the holders of a majority of the outstanding shares of T-Mobile Common Stock in favor of the issuance of T-Mobile Common Stock in the Merger Transactions (the “T-Mobile Stock Issuance Approval”) and in favor of the amendment and restatement of T-Mobile’s Certificate of Incorporation in its entirety in the form attached as Exhibit A to the Business Combination Agreement (the “T-Mobile Charter Amendment” ) (collectively, the “T-Mobile Stockholder Approval”).  Subsequent to the execution of the Business Combination Agreement, Deutsche Telekom entered into a support agreement (the “Deutsche Telekom Support Agreement”), pursuant to which it has agreed to deliver a written consent in favor of the T-Mobile Stock Issuance Approval and the T-Mobile Charter Amendment, which will constitute receipt by T-Mobile of the T-Mobile Stockholder Approval.  As of April 25, 2018, Deutsche Telekom beneficially owned approximately 63.5% of the T-Mobile Common Stock outstanding.  Under the terms of the Deutsche Telekom Support Agreement, Deutsche Telekom and its affiliates are generally prohibited from transferring ownership of T-Mobile Common Stock prior to the earlier of the consummation of the Merger and the termination of the Business Combination Agreement in accordance with its terms.

The consummation of the Transactions is also subject to the satisfaction or waiver, if legally permitted, of certain other conditions, including, among other things, (i) the accuracy of representations and warranties and performance of covenants of the parties, (ii) the effectiveness of the registration statement for the shares of T-Mobile Common Stock to be issued in the Merger Transactions, and the approval of the listing of such shares on the NASDAQ Global Select Market (“NASDAQ”), (iii) receipt of certain regulatory approvals, including approvals of the Federal Communications Commission, applicable state public utility commissions and expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and favorable completion of review by the Committee on Foreign Investments in the United States, (iv) specified minimum credit ratings for T-Mobile on the closing date of the Merger Transactions (after giving effect to the Merger) from at least two of the three credit rating agencies, subject to certain qualifications, and (v) no material adverse effect with respect to Sprint or T-Mobile since the date of the Business Combination Agreement.

The Business Combination Agreement contains representations and warranties and covenants customary for a transaction of this nature. Sprint and SoftBank, and T-Mobile and Deutsche Telekom, are each subject to restrictions on their ability to solicit alternative acquisition proposals and to provide information to, and engage in discussion with, third parties regarding such proposals, except under limited circumstances to permit Sprint’s and T-Mobile’s boards of directors to comply with their respective fiduciary duties.  Subject to certain exceptions, each of the parties has agreed to use its reasonable best efforts to take or cause to be taken actions necessary to consummate the Transactions, including with respect to obtaining required government approvals.  The Business Combination Agreement also contains certain termination rights for both Sprint and T-Mobile.  In the event that T-Mobile terminates the Business Combination Agreement in connection with a failure to satisfy the closing condition related to the specified minimum credit ratings noted above, then in certain circumstances, T-Mobile may be required to pay Sprint $600 million.

In accordance with the Business Combination Agreement, upon consummation of the Transactions, the T-Mobile board of directors will consist of fourteen members, comprising nine directors designated by Deutsche Telekom (of which nine directors, at least two will be independent directors under the listing standards of NASDAQ), four directors designated by SoftBank (of which four directors, at least two will be independent directors under the listing standards of NASDAQ), and T-Mobile’s chief executive officer.  Pursuant to the terms of the Business Combination Agreement, T-Mobile, SoftBank and Deutsche Telekom will also enter into an amended and restated stockholders’ agreement (the “Stockholders Agreement”), a form of which is attached as Exhibit E to the Business Combination Agreement, which will become effective upon the closing of the Transactions, and which will govern, among other things, the composition of T-Mobile’s board of directors following the closing of the Transactions.  The Stockholders Agreement will also set forth certain consent rights for each of SoftBank and Deutsche Telekom over certain material transactions of T-Mobile and will contain a non-compete which will apply to SoftBank, Deutsche Telekom and their respective affiliates, subject to certain exceptions, until such time as SoftBank’s or Deutsche Telekom’s ownership in T-Mobile has been reduced below an agreed threshold.

In addition, pursuant to the terms of the Business Combination Agreement, SoftBank and Deutsche Telekom will enter into a proxy, lock-up and right of first refusal agreement (the “PLR Agreement”), a form of which is attached as Exhibit F to the Business Combination Agreement, which will become effective upon the closing of the Transactions, and which will set forth certain rights and obligations in respect to the shares of T-Mobile Common Stock owned by each of SoftBank, Deutsche Telekom and their respective affiliates to enable Deutsche Telekom to consolidate T-Mobile into Deutsche Telekom’s financial statements following the consummation of the Transactions.  Among other terms, these rights and obligations will require SoftBank to agree to vote its shares of T-Mobile Common Stock as directed by Deutsche Telekom and will restrict SoftBank from transferring its shares of T-Mobile Common Stock in a manner that would prevent Deutsche Telekom from consolidating T-Mobile into Deutsche Telekom’s financial statements following the consummation of the Transactions, subject in each case to certain exceptions set forth in the PLR Agreement.  In addition, the PLR Agreement will impose certain restrictions on

3

SoftBank’s and Deutsche Telekom’s ability to transfer their shares of T-Mobile Common Stock in the four year period following the closing of the Transactions and will provide each of SoftBank and Deutsche Telekom with a right of first refusal with respect to proposed transfers of shares of T-Mobile Common Stock by the other party, subject in each case to certain exceptions and limitations set forth in the PLR Agreement.  As a result of the PLR Agreement, T-Mobile is expected to continue to be a “Controlled Company” for purposes of NASDAQ rules following consummation of the Merger, which provides T-Mobile with exemptions from certain corporate governance requirements under the NASDAQ rules.

Executive Severance Letters

On April 27, 2018, the compensation committee of the board of directors of T-Mobile approved the entry into severance letter agreements (the “Letter Agreements”) with each of J. Braxton Carter, T-Mobile’s Executive Vice President and Chief Financial Officer, Neville R. Ray, T-Mobile’s Executive Vice President and Chief Technology Officer, and Thomas C. Keys, T-Mobile’s President, MetroPCS (collectively, the “Executives”), which became effective on April 29, 2018.

Each Letter Agreement provides that, upon a termination of the applicable Executive’s employment by T-Mobile without “cause” or by the Executive for “good reason” (each as defined in the applicable Letter Agreement) (each, a “qualifying termination”) in either case, within twelve (12) months following the first to occur of (i) the closing of the Transactions or (ii) the date on which T-Mobile publicly announces that the Transactions will not close, and subject to the Executive’s timely execution and non-revocation of a release of claims in favor of T-Mobile and continued compliance with certain non-competition and non-solicitation restrictions for eighteen (18) months following such qualifying termination (or, if such qualifying termination occurs within twelve (12) months following the date on which T-Mobile publicly announces that the Transactions will not close, twelve (12) months), the Executive will receive:

·a lump-sum payment equal to two (2) times the sum of (I) the Executive’s then-current base salary plus (II) the Executive’s then-current target short-term (annual) incentive award;

·a pro-rata short-term incentive award for the calendar year in which the qualifying termination occurs, based on actual performance results for such year;

·any earned, unpaid short-term incentive award for the calendar year ending immediately prior to the year of such qualifying termination;

·full vesting of the Executive’s time-based long-term incentive awards;

·vesting of the Executive’s performance-based long-term incentive awards based on actual performance through the termination date;

·company-paid health coverage for up to eighteen (18) months following such qualifying termination; and

·company-paid outplacement services for twelve (12) months following such qualifying termination.

The foregoing severance benefits will apply in lieu of any other severance benefits that the applicable Executive would otherwise be entitled to receive upon a qualifying termination (unless such other benefits are more favorable to the Executive).

To the extent that any payment or benefit received by any Executive pursuant to his Letter Agreement or otherwise would be subject to an excise tax under Internal Revenue Code Section 4999, such payments and/or benefits will be subject to a “best pay cap” reduction if such reduction would result in a greater net after-tax benefit to the Executive than receiving the full amount of such payments.

The foregoing description of the Letter Agreement is qualified in its entirety by the full text of the Letter Agreement, a copy of which will subsequently be filed with the Securities and Exchange Commission.

The PRSUs are generally subject to the same terms and conditions as the PRSUs granted to Mr. Legere under the Plan on February 15, 2018, except that (i) fifty percent (50%) of the PRSUs will vest on the earlier of the closing of the Transactions or the date on which Mr. Legere’s employment term expires, and (ii) the remaining fifty percent (50%) of the PRSUs will vest on the date on which Mr. Legere’s employment term expires, subject to Mr. Legere’s continued employment through the applicable vesting date (except as otherwise set forth in his employment agreement and PRSU award agreement).

The Legere Amendment also amends the severance benefits that Mr. Legere will, subject to his timely execution and non-revocation of a release of claims in favor of T-Mobile, be eligible to receive upon a termination of his employment by T-Mobile without “cause” (including due to the expiration of the employment term) or by Mr. Legere for “good reason” (each as defined in Mr. Legere’s employment agreement) to include (a) company-paid COBRA coverage for up to eighteen (18) months following such termination and (b) company payment or reimbursement for an exclusive office and exclusive executive assistant for eighteen (18) months following such termination (capped at $25,000 per month).

The Sievert Amendment also amends Mr. Sievert’s compensation term sheet to provide that, upon Mr. Sievert’s termination of the employment by T-Mobile without “cause” or due to a “constructive termination” (each as defined in Mr. Sievert’s compensation term sheet), then, subject to his timely execution and non-revocation of a release of claims in favor of T-Mobile, Mr. Sievert will be entitled to receive the same severance payments and benefits provided under the Letter Agreements described above under the heading “Executive Letter Agreements,” except that Mr. Sievert’s performance-based long-term incentive awards will be treated as follows:

·A portion of each performance-based long-term incentive award, determined by multiplying (i) the total number of shares or units, as applicable, subject to such award by (ii) a fraction, the numerator of which is the number of days between the commencement of the applicable performance period in effect as of Mr. Sievert’s termination of employment through the date of such termination, and the denominator of which is the number of days in the full performance period, will vest based on actual performance through the termination date; and

6

·A portion of each performance-based long-term incentive award, determined by multiplying (i) the total number of shares or units, as applicable, subject to such award by (ii) a fraction, the numerator of which is the number of days between the date of Mr. Sievert’s termination of employment and the end of the applicable performance period in effect as of such termination, and the denominator of which is the number of days in the full performance period, will vest at target.

The foregoing description of the Sievert Amendment is qualified in its entirety by the full text of the Sievert Amendment, a copy of which will subsequently be filed with the Securities and Exchange Commission.

Cautionary Statement Regarding Forward-Looking Statements

This communication contains certain forward-looking statements concerning T-Mobile, Sprint and the proposed transaction between T-Mobile and Sprint. All statements other than statements of fact, including information concerning future results, are forward-looking statements. These forward-looking statements are generally identified by the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “could” or similar expressions. Such forward-looking statements include, but are not limited to, statements about the benefits of the proposed transaction, including anticipated future financial and operating results, synergies, accretion and growth rates, T-Mobile’s, Sprint’s and the combined company’s plans, objectives, expectations and intentions, and the expected timing of completion of the proposed transaction. There are several factors which could cause actual plans and results to differ materially from those expressed or implied in forward-looking statements. Such factors include, but are not limited to, the failure to obtain, or delays in obtaining, required regulatory approvals, and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction, or the failure to satisfy any of the other conditions to the proposed transaction on a timely basis or at all; the occurrence of events that may give rise to a right of one or both of the parties to terminate the business combination agreement; adverse effects on the market price of T-Mobile’s or Sprint’s common stock and on T-Mobile’s or Sprint’s operating results because of a failure to complete the proposed transaction in the anticipated timeframe or at all; inability to obtain the financing contemplated to be obtained in connection with the proposed transaction on the expected terms or timing or at all; the ability of T-Mobile, Sprint and the combined company to make payments on debt or to repay existing or future indebtedness when due or to comply with the covenants contained therein; adverse changes in the ratings of T-Mobile’s or

8

Sprint’s debt securities or adverse conditions in the credit markets; negative effects of the announcement, pendency or consummation of the transaction on the market price of T-Mobile’s or Sprint’s common stock and on T-Mobile’s or Sprint’s operating results, including as a result of changes in key customer, supplier, employee or other business relationships; significant transaction costs, including financing costs, and unknown liabilities; failure to realize the expected benefits and synergies of the proposed transaction in the expected timeframes or at all; costs or difficulties related to the integration of Sprint’s network and operations into T-Mobile; the risk of litigation or regulatory actions; the inability of T-Mobile, Sprint or the combined company to retain and hire key personnel; the risk that certain contractual restrictions contained in the business combination agreement during the pendency of the proposed transaction could adversely affect T-Mobile’s or Sprint’s ability to pursue business opportunities or strategic transactions; effects of changes in the regulatory environment in which T-Mobile and Sprint operate; changes in global, political, economic, business, competitive and market conditions; changes in tax and other laws and regulations; and other risks and uncertainties detailed in T-Mobile’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 and in its subsequent reports on Form 10-Q, including in the sections thereof captioned “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements,” as well as in its subsequent reports on Form 8-K, all of which are filed with the SEC and available at www.sec.gov and www.t-mobile.com. Forward-looking statements are based on current expectations and assumptions, which are subject to risks and uncertainties that may cause actual results to differ materially from those expressed in or implied by such forward-looking statements. Given these risks and uncertainties, persons reading this communication are cautioned not to place undue reliance on such forward-looking statements.

(iii)Each Sprint PSU Award, whether vested or unvested, that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, be converted into a T-Mobile RSU Award on the terms and conditions (including, if applicable, any continuing vesting requirements, but not the performance-based vesting conditions applicable to such Sprint PSU Awards immediately prior to the Effective Time) under the applicable plan and award agreement in effect immediately prior to the Effective Time, with respect to a number of shares of T-Mobile Common Stock, rounded up to the nearest whole share, determined by multiplying (A) the number of shares of Sprint Common Stock subject to such Sprint PSU Award immediately prior to the Effective Time by (B) the Exchange Ratio.  Any accrued but unpaid dividend equivalents with respect to any such Sprint PSU Award will be assumed and become an obligation with respect to the applicable T-Mobile RSU Award.  For purposes of this Section 3.3(a)(iii), the number of shares of Sprint Common Stock subject to each Sprint PSU Award immediately prior to the Effective Time shall be based on the assumed level of performance to equal (1) in the case of a Sprint TIA Award the greatest of (x) the volume-weighted average price of Sprint Common Stock over any 150-calendar day period as specified in the applicable award agreement as of the Effective Time, (y) the volume-weighted average price of Sprint Common Stock over the five (5) consecutive trading day period ending with the second (2nd) complete trading day prior to the Effective Time and (z) the volume-weighted average price of Sprint Common Stock equal to 100% of the target award; and (2) in the case of a Sprint PSU Award other than a Sprint TIA Award, in respect of outstanding performance periods as of the Effective Time, the target number of shares of Sprint Common Stock underlying such Sprint PSU Award and in respect of completed performance periods as of the Effective Time, the actual number of shares of Sprint Common Stock underlying such Sprint PSU Award.

(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.

except as, individually or in the aggregate, would not reasonably be expected to be material to Sprint and its subsidiaries, taken as a whole.  None of Sprint or its subsidiaries has, nor to the knowledge of Sprint has any other party to any such lease, claimed that any party to any such lease is in breach or default under such lease, and any past breach or default has been waived, cured or otherwise settled, in each case, except as, individually or in the aggregate, would not reasonably be expected to be material to Sprint and its subsidiaries, taken as a whole.  No party to any such lease has claimed in writing nor, to the knowledge of Sprint, has any party threatened in writing that Sprint or any of its subsidiaries is in violation of or default under any such lease, or that such party has the right to terminate such lease, in each case, except as, individually or in the aggregate, would not reasonably be expected to be material to Sprint and its subsidiaries, taken as a whole.  To the knowledge of Sprint, all FCC licenses underlying all such leases were validly issued and are in full force and effect, and are not subject to proceedings or threatened proceedings that could reasonably be expected to result in the revocation, modification, restriction, cancellation, termination, suspension or non-renewal of any such FCC license, in each case, except as, individually or in the aggregate, would not reasonably be expected to be material to Sprint and its subsidiaries, taken as a whole.
