A Stockholder that Pledges a Share to secure any Obligation must provide a written agreement from the secured party to whom such Share has been Pledged acknowledging and agreeing to be bound by such conditions, including, in the case of a Required Consolidation Share, acknowledging and agreeing that any person that obtains a Required Consolidation Share as a result of a foreclosure of such Pledge on or prior to the fourth anniversary of the Effective Time shall be subject to the Proxy and the obligations set forth in Sections 2, 3, 4 and 5 as if such person were a SoftBank Stockholder under this Agreement, and any person that obtains a Required Consolidation Share as a result of a foreclosure of such Pledge after the fourth anniversary of the Effective Time shall be subject to the Proxy and the obligations set forth in Sections 2, 3(b), 4 and 5 as if such person were a SoftBank Stockholder under this Agreement.

(iv)    A Stockholder must provide at least 10 days’ written notice to the other Stockholder prior to each Pledge of any of the first Stockholder’s Shares. Such notice shall set forth the terms and conditions of such Pledge (including a copy of the agreements setting forth such terms and conditions), the Obligations and the name(s) and address(es) of all Persons to whom such Shares are Pledged, and shall certify that the Pledge complies with the terms and conditions set forth in this Agreement.

(v)    A Stockholder that has Pledged any Shares shall provide prompt written notice to the other Stockholder of any default of any Obligation.

(c)    Void Transfers. Any Transfer (including Pledge) of a Share not effected in accordance with this Section 3 shall be null and void ab initio.

4.    General Right of First Refusal.

(a)    Applicability. Until the earliest to occur of (i) the Proxy Fall Away Date and (ii) such time as either the SoftBank Stockholder or the DT Stockholder no longer

-13-

Beneficially Owns at least 5% of the Voting Securities outstanding as of the Effective Time (such earlier date, the “ROFR Fall Away Date”), neither Stockholder shall Transfer any of its Shares, whether such Transfer occurs during or after the Lock-up Period, unless such Stockholder shall have first complied with Section 4.2 of the Stockholders’ Agreement and this Section 4 with respect to such Transfer of Shares; provided that this Section 4 shall not apply to (i) any Transfer described in Section 3(a)(i), 3(a)(iii) or 3(a)(iv), (ii) any Pledge of a Share or any Transfer in connection with a foreclosure of a Pledged Share (it being understood that any Transfer in connection with a foreclosure of a Pledged Share shall be subject to Section 5), or (iii) any Transfer pursuant to a Sale of the Company (as defined in the Stockholders’ Agreement).

(b)    Transfer Notice. Any Transfer of Shares subject to Section 4(a) (the “ROFR Shares”) by a Stockholder (the “Transferring Stockholder”) to any Person or Persons (the “Proposed Transferee(s)”) shall not occur and shall be null and void ab initio unless, prior to the consummation of such Transfer, the Transferring Stockholder shall, at least 20 Business Days prior to the date that such Transfer is to be consummated, deliver a written notice (the “Offer Notice”) to the other Stockholder (the “Offeree Stockholder”) (i) setting forth (A) the number and type of Shares proposed to be Transferred by the Transferring Stockholder, (B) whether the proposed Transfer is an Open Market Transfer or not an Open Market Transfer, and (C) if the proposed Transfer is not an Open Market Transfer, the name(s) and address(es) of the Proposed Transferee(s), the per Share purchase price, the form of consideration and the terms and conditions of payment offered by the Proposed Transferee(s), and any other material terms and conditions of the proposed Transfer (including a description of any non-cash consideration in sufficient detail to permit a valuation thereof) (collectively, the “Offer Terms”), (ii) in the case of a proposed Transfer that is not an Open Market Transfer, including a written certification that (A) the Offer Terms represent a bona fide proposal for the Transfer of the Shares to the Proposed Transferee(s) as set forth in the Offer Notice and (B) the Transferring Stockholder believes in good faith that a binding agreement for the Transfer could be obtainable on the terms set forth in the Offer Notice and (iii) including, if the proposed Transfer is an Open Market Transfer, a good-faith written estimate of the per-share amount of any applicable underwriting discounts and fees, if any, payable by the Proposed Transferee in the proposed Open Market Transfer, and if the proposed Transfer is not an Open Market Transfer, a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed Transfer.

(c)    Option of the Offeree Stockholder. The Offer Notice shall constitute, for a period of 20 Business Days after the delivery of the Offer Notice, a binding, irrevocable and exclusive offer to sell to the Offeree Stockholder (or any Controlled Affiliate of the Offeree Stockholder designated by the Offeree Stockholder or as part of a “group” including the Offeree Stockholder as contemplated by Section 13d-5(b) of the Exchange Act) (the “Designated Transferee”) any or all of the ROFR Shares (i) in the case of a proposed Transfer that is not an Open Market Transfer, on the Offer Terms (at the price per Share set forth therein); provided that if the Offer Terms provide for payment of any non-cash consideration, the Offeree Stockholder may elect to pay the purchase price in respect of such non-cash consideration in cash in an amount that is equal to the fair market value of such non-cash consideration described in the Offer Terms, as determined in good faith and mutually agreed by the Transferring Stockholder and the Offeree Stockholder (provided that, if the Transferring Stockholder and the Offeree Stockholder shall be unable to so mutually agree within 10 Business Days of the

-14-

delivery of the Offer Notice, then either party may commence the valuation process described in Section 4(e) and the periods set forth in this Section 4(c) shall be tolled for, and such periods (or the remaining portion thereof) shall recommence only upon a final and binding determination of fair market value pursuant to, such valuation process); and (ii) in the case of a proposed Transfer that is an Open Market Transfer, at the Open Market Transfer Price; provided that, in each of clauses (i) and (ii), during such 20-Business-Day period, the Transferring Stockholder may not effect the proposed Transfer to the Proposed Transferee(s) or pursuant to any Open Market Transfer, as applicable (unless prior to the expiration thereof, the Offeree Stockholder provides written notice to the Transferring Stockholder that it is not electing to purchase the ROFR Shares). To accept such offer, an Offeree Stockholder shall deliver written notice (the “Acceptance Notice”) to the Transferring Stockholder on or prior to the end of such 20-Business-Day period setting forth (A) its binding acceptance of such offer, (B) the identity of the Designated Transferee, (C) the planned date for purchase of the ROFR Shares, which shall be a reasonable date within 120 days from the date of the Purchase Offer (the “Planned Purchase Date”) and (D) the number of ROFR Shares to be purchased, whereupon the Transferring Stockholder will be obligated to sell, and the Offeree Stockholder will be obligated to purchase, the ROFR Shares in accordance with the Offer Terms or Open Market Transfer Price, as applicable, or such other terms and conditions as may be agreed between the Transferring Stockholder and the Offeree Stockholder. The closing of such purchase and sale shall occur on the Planned Purchase Date or at such time and place as the Transferring Stockholder and the Offeree Stockholder may agree, pursuant to an agreement containing reasonable and customary representations and warranties and other terms and conditions.

(d)    Ability to Sell of the Transferring Stockholder. If (i) the Offeree Stockholder does not deliver an Acceptance Notice on or prior to the end of the 20-Business-Day period set forth in Section 4(c), (ii) the Offeree Stockholder or the Designated Transferee, as the case may be, has not paid the full Transfer price for the ROFR Shares on such terms and conditions as may be agreed between the Transferring Stockholder and the Offeree Stockholder or, in the absence of such agreement, in accordance with the Offer Terms or the Open Market Transfer Price, as applicable, or (iii) the Acceptance Notice is not for all the ROFR Shares, the Transferring Stockholder may, during the 120-day period immediately following the earlier of the end of such 20-Business-Day period and the delivery of the Acceptance Notice, Transfer the ROFR Shares (or the remaining ROFR Shares, in the event the Acceptance Notice is not for all the ROFR Shares) (A) if the proposed Transfer is an Open Market Transfer, pursuant to an Open Market Transfer, and (B) if the proposed Transfer is not an Open Market Transfer, to the Proposed Transferee(s) for no less than the per Share purchase price and the form of consideration, and on substantially similar terms and conditions of payment set forth in the Offer Terms, and otherwise on terms and conditions no more favorable to the Proposed Transferee(s) than the Offer Terms; provided that, if the Transferring Stockholder does not consummate the Transfer of the ROFR Shares in accordance with the foregoing within such 120-day period, any attempt to Transfer such ROFR Shares shall again be subject to the provisions of this Section 4.

(e)    Valuation Process for Non-Cash Consideration. If any Offer Terms provide for payment of any non-cash consideration, then the Transferring Stockholder and the Offeree Stockholder shall negotiate in good faith to determine the fair market value of such non-cash consideration. If they are unable to agree on such fair market value within 10 Business Days of the delivery of the Offer Notice, then either the Transferring Stockholder or the Offeree

-15-

Stockholder may commence the valuation process described in this Section 4(e) by providing written notice to the other party (such notice, a “Valuation Process Notice”). In the event a Valuation Process Notice is delivered, then within 10 Business Days of the delivery of the Valuation Process Notice, each of the Transferring Stockholder and the Offeree Stockholder shall appoint an internationally recognized investment banking firm (an “Appointed Bank”). Each of the Transferring Stockholder and the Offeree Stockholder shall instruct its Appointed Bank to determine, by no later than 20 Business Days after being appointed, its best estimate of the fair market value of the non-cash consideration, based on the customary methodologies that such Appointed Bank in its professional experience deem relevant to such a determination. On the 45th Business Day following delivery of the Valuation Process Notice or such earlier date as mutually agreed between the Transferring Stockholder and the Offeree Stockholder, each Appointed Bank shall present to the other party and its Appointed Bank its determination of the fair market value of such non-cash consideration. In the event the fair market values determined by the two Appointed Banks are within 10% of one another (determined by reference to the higher of the two), the fair market value shall be the average of those two estimates and such determination of the fair market value of the non-cash consideration shall be final and binding on the Transferring Stockholder and the Offeree Stockholder. In the event the fair market values determined by the two Appointed Banks are not within 10% of one another (determined by reference to the higher of the two), the Appointed Banks shall mutually select a third internationally recognized investment banking firm (the “Independent Bank”) to determine, by no later than 20 Business Days after being appointed, its best estimate of the fair market value of the non-cash consideration, based on the customary methodologies that such Independent Bank in its professional experience deem relevant to such a determination. The fair market value of the non-cash consideration shall then be determined by the Independent Bank, and such resulting determination shall be final and binding on the Transferring Stockholder and the Offeree Stockholder.

5.    Right of First Refusal upon Foreclosure of Pledged Shares.

(a)    Applicability. Until the ROFR Fall Away Date, neither Stockholder shall permit any Person to Transfer Pledged Shares in connection with any foreclosure without first complying with the procedures set forth in this Section 5, and neither Stockholder shall enter into any agreement or arrangement relating to a Pledge that is inconsistent with or would have the effect of circumventing the process and requirements set forth in this Section 5.

(b)    Pledge ROFR Notice. In the event that a financial institution, brokerage firm or other Person that is the creditor in respect of any Obligation (such Person, including any agent, trustee or other Person acting in a similar capacity on behalf of such creditor, being a “Pledge Counterparty”) delivers a notice of event of default or a similar event or consequence pursuant to any agreement or arrangement relating to an Obligation secured by a Pledge of Shares, it shall concurrently deliver a written notice (the “Pledge ROFR Notice”) to the other Stockholder (the “Pledge ROFR Offeree Stockholder”), which notice shall include a copy of the notice delivered to the first Stockholder and shall set forth (i) the number of Pledged Shares securing the Obligation that is in default or subject to a similar event or consequence (the “Pledge ROFR Shares”), (ii) the number of Pledge ROFR Shares that are Pledged Required Consolidation Shares or Pledged Excess Shares, (iii) the VWAP for the ten consecutive trading days immediately preceding the date of the Pledge ROFR Notice (the “Pledge ROFR Price”),

-16-

(iv) the cure period applicable to such default, event or consequence and the earliest date and time following such cure period on which the Pledge Counterparty may foreclose on the Pledge ROFR Shares (together, the “Pledge ROFR Foreclosure Period”), which Pledge ROFR Foreclosure Period shall be no less than 2 Business Days, subject to notice, cure and information rights set forth in the agreements for such Pledged Shares, and (v) all other material terms and conditions related to the right of first refusal described in this Section 5.

(c)    Option of the Pledge ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇. ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇ Notice shall constitute, during the Pledge ROFR Foreclosure Period, a binding, irrevocable and exclusive offer to sell to the Pledge ROFR Offeree Stockholder (or any Controlled Affiliate of the Pledge ROFR Offeree Stockholder designated by the Pledge ROFR Offeree Stockholder or as part of a “group” including the Pledge ROFR Offeree Stockholder as contemplated by Section 13d-5(b) of the Exchange Act) (the “Designated Pledge ROFR Transferee”) any or all of the Pledge ROFR Shares on the terms and at the Pledge ROFR Price set forth in the Pledge ROFR Notice; provided that during the Pledge ROFR Foreclosure Period, the Pledge Counterparty may not effect a foreclosure sale or other Transfer of the Pledge ROFR Shares unless prior to the expiration thereof, the Pledge ROFR Offeree Stockholder provides written notice to the Pledge Counterparty that it has elected not to purchase the Pledge ROFR Shares. The Pledge ROFR Offeree Stockholder may elect to purchase any or all of the Pledge ROFR Shares by delivering a written notice (the “Pledge ROFR Acceptance Notice”) to both the Stockholder that has Pledged such Shares and the Pledge Counterparty on or prior to the end of the Pledge ROFR Foreclosure Period setting forth (i) its irrevocable acceptance of such offer, (ii) the identity of the Designated Pledge ROFR Transferee, (iii) its commitment to purchase the Pledge ROFR Shares on a date that is on or prior to the last day of the Pledge ROFR Foreclosure Period (the “Pledge ROFR Purchase Date”), and (iv) the number of Pledge ROFR Shares to be purchased, whereupon both the Stockholder that has Pledged such Shares and the Pledge Counterparty will be obligated to sell, and the Pledge ROFR Offeree Stockholder will be obligated to purchase, such number of Pledge ROFR Shares in accordance with the terms set forth in the Pledge ROFR Notice or such other terms and conditions as may be agreed between the Pledge ROFR Offeree Stockholder and the Pledge Counterparty. The closing of such purchase and sale shall occur on the Pledge ROFR Purchase Date or at such time and place as the Pledge ROFR Offeree Stockholder and the Pledge Counterparty may agree, pursuant to an agreement containing reasonable and customary representations and warranties and other terms and conditions.

6.    Certain Prohibited Acquisitions of Shares.

(a)    Until the Proxy Fall Away Date, SoftBank agrees that, without the prior written consent of DT, it shall not, and shall cause its Affiliates not to, directly or indirectly, alone or in concert with any other Person, acquire, offer to acquire or agree to acquire (including from the Company) Beneficial Ownership of any Voting Securities if, following such acquisition, the ratio of (i) the number of Shares Beneficially Owned by the SoftBank Stockholder to (ii) the number of Shares Beneficially Owned by the DT Stockholder would be greater than the ratio of 49.9% to 50.1%.

(a)    Injunctive Relief.
