2. Preferred Stock that is redeemed, purchased or retired by the Corporation shall assume the status of authorized and unissued Preferred Stock and may thereafter, subject to the provisions of any Certificate of Designation providing for the issue of any particular series of Preferred Stock, be reissued in the same manner as authorized and unissued Preferred Stock.

(C)Common Stock. All shares of Common Stock shall be identical except as expressly set forth in this Article IV. Each share of Common Stock shall have attributed to it the number of votes set forth in Section (E) below.

(D)Rights of Holders of Capital Stock.

1.Holders of Preferred Stock. Except as such rights may be specifically limited herein, the rights of holders of Preferred Stock shall be as set forth in any Certificate of Designation relating thereto.

2.Holders of Common Stock. The rights of holders of Common Stock shall be as set forth in this Section (D)(2), except with respect to such rights as are set forth in Section (E) of this Article IV.

(a)Dividend Rights. Subject to the prior rights of holders of all classes of stock at the time outstanding having prior rights as to dividends, the holders of the Common Stock shall be entitled to receive, when and as declared by the Board of Directors, out of any assets of the Corporation legally available therefor, such dividends, distributed ratably among the holders of the Common Stock in proportion to the number of shares of such Common Stock owned by each such holder, as may be declared from time to time by the Board of Directors.

(b)Liquidation Preference. Subject to the prior rights of holders of all classes of stock at the time outstanding having prior rights as to distributions in the event of liquidation, dissolution or winding up of the Corporation, and after any and all distributions are made in accordance therewith, in such event, either voluntary or involuntary, the remaining assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Common Stock in proportion to the number of shares of such Common Stock owned by each such holder.

3.Redemption.

(a) Subject to Section (D)(3)(e) of this Article IV, if, at any time, a holder of shares of Common Stock or Preferred Stock acquires additional shares of Common Stock or Preferred Stock, or is otherwise attributed with ownership of such shares, that would cause the Corporation to violate (in each case, an “FCC Violation”) (A) any requirement of the Federal Communications Commission (“FCC”) regarding foreign ownership (collectively, “Foreign Ownership Requirements”) or (B) any other rule or regulation of the FCC applicable to the Corporation, then the Corporation may, at the option of the Board of Directors, redeem from the holder or holders causing such FCC Violation a sufficient number of shares of Common Stock or Preferred Stock to eliminate the FCC Violation by paying in cash therefor a sum equal to the Redemption Price. The “Redemption Price” (herein so called) shall equal such price as is mutually determined by such stockholders and the Corporation, or, if no mutually acceptable agreement can be reached, shall equal either (i) seventy-five percent (75%) of the fair market

-3-

value of the Common Stock (the “Common Stock Fair Market Value”) or the Fair Market Value of the Preferred Stock, as applicable, where such holder caused the FCC Violation, or (ii) one hundred percent (100%) of the Common Stock Fair Market Value or the Fair Market Value of the Preferred Stock, as applicable, where the FCC Violation was caused by no fault of the holder;provided,however, that the determination of whether such party caused the FCC Violation shall be made, in good faith, by the disinterested members of the Board of Directors. As used in this Section (D)(3), the Common Stock Fair Market Value shall be determined as follows:

(i) if the Common Stock is publicly traded at the time of determination, the average of the closing prices for the Common Stock on all domestic securities exchanges on which the Common Stock may at the time be listed, or, if there have been no sales of the Common Stock on any such exchange on such day, the average of the highest bid and lowest asked prices for the Common Stock on all such exchanges at the end of such day, or, if on any day the Common Stock is not so listed, the average of the representative bid and asked prices for the Common Stock quoted on the NASDAQ system as of the close of trading on such day, or if on any day such security is not quoted in the NASDAQ system, the average of the highest bid and lowest asked prices for the Common Stock on such day in the domesticover-the-counter market as reported by the Pink Sheets, LLC, or any similar successor organization, in each such case averaged over the30-day period ending three days prior to the Redemption Date (as defined in Section (D)(3)(b) of this Article IV); and

(ii) if the Common Stock is not publicly traded at the time of determination then, the fair value of the Common Stock as determined in good faith by the disinterested members of the Board of Directors.

As used in this Section (D)(3), the Preferred Stock Fair Market Value shall mean the value determined by multiplying the Common Stock Fair Market Value by the number of shares of Common Stock into which the share of Preferred Stock is then convertible.

(b) At least five (5) but no more than thirty (30) days prior to any date on which Common Stock or Preferred Stock is to be redeemed (a “Redemption Date”), written notice shall be sent by mail, first class postage prepaid, overnight mail, facsimile, or electronic mail to each holder of record (at the close of business on the business day next preceding the day on which notice is given) of the shares of Common Stock or Preferred Stock to be redeemed, at the address last shown on the records of the Corporation for such holder, notifying such holder of the redemption to be effected, specifying the number of shares to be redeemed from such holder, the Redemption Date, the Redemption Price, the place at which payment may be obtained and calling upon such holder to surrender to the Corporation, in the manner and at the place designated, his, her or its certificate or certificates representing the shares to be redeemed (the “Redemption Notice”). Except as provided in Section (D)(3)(c) of this Article IV, on or after the Redemption Date, each holder of shares of Common Stock or Preferred Stock to be redeemed shall surrender to the Corporation the certificate or certificates representing such shares, in the manner and at the place designated in the Redemption Notice, and thereupon the Redemption Price of such shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof and each surrendered certificate shall be canceled. In the event less than all the shares represented by any such certificate are redeemed, a new certificate shall be issued representing the unredeemed shares.

-4-

(c) From and after the Redemption Date, unless there shall have been a default in payment of the Redemption Price, all rights of the holders of shares of Common Stock or Preferred Stock designated for redemption in the Redemption Notice as holders of such shares of Common Stock or Preferred Stock (except the right to receive the Redemption Price without interest upon surrender of their certificate or certificates) shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purpose whatsoever. If the funds of the Corporation legally available for redemption of shares of Common Stock or Preferred Stock on any Redemption Date are insufficient to redeem the total number of shares of Common Stock or Preferred Stock to be redeemed on such date, those funds which are legally available will be used to redeem the maximum possible number of such shares ratably among the holders of such shares to be redeemed based upon their holdings of Common Stock or Preferred Stock to be redeemed. The shares of Common Stock or Preferred Stock not redeemed shall remain outstanding and entitled to all the rights and preferences provided herein. At any time thereafter when additional funds of the Corporation are legally available for the redemption of shares of Common Stock or Preferred Stock, such funds will immediately be used to redeem the balance of the shares which the Corporation has become obligated to redeem on any Redemption Date but which it has not redeemed.

(d) Prior to effecting any such redemption, the Corporation shall provide any holder of Common Stock or Preferred Stock to be redeemed with reasonable prior written notice of the reason giving rise to the Corporation’s redemption right and, if requested to do so by such holder, the Corporation shall reasonably cooperate with such affected holder in arranging another method to minimize or eliminate the reason giving rise to the Corporation’s redemption right, including, but not limited to and not in any particular order of priority, preparing and filing waiver requests with the FCC, developing alternative ownership structures, assisting with a sale of such holders’ interest in the Corporation, amending the Corporation’s Certificate of Incorporation and obtaining FCC approvals for such transaction.

(e) The provisions of Sections (D)(3)(a) through (D)(3)(d) of this Article IV shall not apply to the DT Stockholder or the SoftBank Stockholder (each as defined in that certain Amended and Restated Stockholders’ Agreement, dated as of April 1, 2020, by and among the Corporation, Deutsche Telekom AG and SoftBank Group Corp., as it may be amended from time to time (the “Stockholders’ Agreement”)) (each, a “Stockholder”, and collectively, the “Stockholders”), any acquisition of shares of Common Stock or Preferred Stock by a Stockholder or any of its subsidiaries, or any ownership of such shares otherwise attributed to a Stockholder or any of its subsidiaries, and the Corporation shall not have the authority under Sections (D)(3)(a) through (D)(3)(d) of this Article IV to redeem any shares of Common Stock or Preferred Stock Beneficially Owned, directly or indirectly, by a Stockholder or any of its subsidiaries, in each case notwithstanding anything to the contrary therein. In the event that any waivers or approvals are required from the FCC in order for a Stockholder or any of its subsidiaries to acquire or hold Common Stock or Preferred Stock, such Stockholder and its subsidiaries shall cooperate to secure such waivers or approvals and abide by any conditions related to such waivers or approvals.

-5-

(E)Voting Rights.

1.Common Stock. The holders of Common Stock shall have the right to vote on every matter submitted to a vote of the holders of capital stock of the Corporation other than any matter on which only the holders of one or more other classes or series of capital stock of the Corporation are entitled to vote separately as a class.

INDEMNIFICATION

(A) The Corporation shall, to the fullest extent permitted by the DGCL in effect on the date of the effectiveness of this Certificate of Incorporation, and to such greater extent as the DGCL may thereafter permit, indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative by reason of the fact that he is or was a director, manager, member, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, manager, member, officer, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, liabilities, losses, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding.

(B) To the extent that a director, manager, member, officer, employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section (A) of this Article IX, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith.

(C) Any indemnification under Section (A) of this Article IX (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in the DGCL. Such determination shall be made (i) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (ii) if such a quorum is not obtainable, or, even if obtainable, a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (iii) by the stockholders of the Corporation.

(D) Expenses (including attorneys’ fees) incurred by an officer, director, a manager of a Corporation limited liability company, or a member of a management committee of a Corporation limited liability company, in defending any civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director, officer, manager or member to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation as authorized in this Article IX. Such expenses (including attorneys’ fees) incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Board of Directors deems appropriate.

-11-

(E) The indemnification and advancement of expenses provided by, or granted pursuant to, the other sections of this Article IX shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any law, Bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in an official capacity and as to action in another capacity while holding such office.
