the option of the holders of the guarantees under the Designated Senior Debt, in Cash Equivalents, any distribution of any kind or character from the Subsidiary Guarantor to which the holders of the 2028 Guaranteed Notes (by virtue of the Subsidiary Guarantees) would be entitled shall be made to the holders of the guarantees under the Designated Senior Debt.

(c)    Defaults Under Designated Senior Indebtedness. Each Subsidiary Guarantor may not make any payment in respect of its Subsidiary Guarantee (except for payments to the Trustee under Section of the Indenture and except in Permitted Junior Securities or from the trust (if any) created in connection with the legal defeasance or covenant defeasance of the 2028 Guaranteed Notes by the Company) if:

(i)    a payment default on a guarantee of Designated Senior Debt of such Subsidiary Guarantor has occurred and is continuing beyond any applicable grace period; or

(ii)    any other default occurs and is continuing on any guarantee of Designated Senior Debt of such Subsidiary Guarantor that permits the holders of that guarantee of Designated Senior Debt to accelerate its maturity and the Trustee receives a notice of such default (a “Payment Blockage Notice”) from the Company, Sprint Communications or the holders of guarantees of such Designated Senior Debt.

No new Payment Blockage Notice may be delivered unless and until (x) 360 days have elapsed since the delivery of the immediately prior Payment Blockage Notice and (y) all scheduled payments of principal, premium, if any, and interest on the 2028 Guaranteed Note that have come due have been paid in full in cash. No non-payment default that existed or was continuing on the date of delivery of a Payment Blockage Notice to the Trustee will be, or be made, the basis for a subsequent Payment Blockage Notice.

(f)    Monies Held in Trust. If the Trustee receives a payment in respect of the 2028 Guaranteed Notes when (1) the payment is prohibited by the subordination provisions of this Section 4.06 and (2) the Trustee has received written notice that the payment is prohibited, then the Trustee will hold the payment in trust for the benefit of the holders of the applicable Designated Senior Debt. Upon the written request of such holders, the Trustee will deliver the amounts held in trust to those holders.

(1)    the Company or Sprint Communications, as applicable, has made or will make effective provision whereby the Outstanding 2028 Guaranteed Notes are equally and ratably secured with (or prior to) all other indebtedness for borrowed money secured by such Lien for so long as any such other indebtedness for borrowed money is so secured;

(2)    the Lien is a Permitted Lien; or

(3)    (i) in the case of the Company, the aggregate principal amount of indebtedness secured by the Lien and any other such Lien, other than Permitted Liens, does not exceed 15% of the Company’s Consolidated Net Tangible Assets (for the avoidance of doubt, calculated at the time of the incurrence of such indebtedness); and

(ii)    in the case of Sprint Communications, the aggregate principal amount of indebtedness (excluding any Guaranteed Indebtedness incurred pursuant to the $8.0 billion basket referred to in Section 1010) secured by the Lien and any other such Lien, other than Permitted Liens, does not exceed 15% of Sprint Communications’s Consolidated Net Tangible Assets (for the avoidance of doubt, calculated at the time of the incurrence of such indebtedness).

For the avoidance of doubt, Sprint Communications may incur any Guaranteed Indebtedness so long as the guarantees by Subsidiary Guarantors of such Guaranteed Indebtedness are subordinated to the guarantees by such Subsidiary Guarantors of Designated Senior Debt to a greater extent than the Subsidiary Guarantees of the Sprint Communications Guarantee are subordinated to the guarantees of Designated Senior Debt.

Section 1011. Anti-Layering.

The Company and Sprint Communications will not permit or cause any Subsidiary Guarantor to directly, or indirectly, create, incur, issue or assume any guarantee that is both subordinate in right of payment to the guarantees of Designated Senior Debt of such Subsidiary Guarantor and senior in any respect in right of payment to the Subsidiary Guarantees under the 2028 Guaranteed Notes. For the purposes of the foregoing, no indebtedness or guarantee will be deemed to be subordinated in right of payment to any indebtedness or guarantee of any Subsidiary Guarantor solely by reason of any Liens or by virtue of the fact that the holders of any secured indebtedness have entered into intercreditor agreements giving one or more of such holders priority over the other holders in the collateral held by them.”

SECTION 5.05    Amendments to Article XIII. Solely with respect to the 2028 Guaranteed Notes, Section 1303 of the Indenture is amended by inserting the following immediately after the phrase “1006 through 1008 inclusive”:

Any calculation made pursuant to this Section 6.01(a) shall not include any discounted amount with respect to the interest and principal payments due on the Stated Maturity of the 2028 Guaranteed Notes and shall instead include the discounted amount with respect to the interest and principal payments that would be payable upon redemption of the 2028 Guaranteed Notes on the First Par Call Date.

(b)    The 2028 Guaranteed Notes will be redeemable at the Company’s option, in whole or in part, at any time on or after the First Par Call Date, at a Redemption Price equal to 100% of the principal amount of the 2028 Guaranteed Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the applicable Redemption Date.

SECTION 6.02    Interest on 2028 Guaranteed Notes Redeemed; Deposit of Applicable Redemption Price. On and after the Redemption Date, interest will cease to accrue on the 2028 Guaranteed Notes or any portion thereof called for redemption, unless the Company defaults in the payment of the applicable Redemption Price. On or before 11:00 AM, EST on the Redemption Date, the Company will deposit with the Paying Agent, or the Trustee, money sufficient to pay the applicable Redemption Price of the 2028 Guaranteed Notes to be redeemed on such date.

SECTION 6.03    Special Mandatory Redemption. In the event that the T-Mobile Transaction is consummated prior to the Stated Maturity of the 2028 Guaranteed Notes (the “Special Mandatory Redemption Event”), the Company shall redeem all of the 2028 Guaranteed Notes (the “Special Mandatory Redemption”) at a price equal to 100% of the principal amount of the 2028 Guaranteed Notes, plus accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption Date (as defined below) (such price, the “Special Mandatory Redemption Price”).

Notice of the Special Mandatory Redemption (the “Special Mandatory Redemption Notice”) shall be provided to the Trustee and to each registered Holder of the 2028 Guaranteed Notes at least three days but not more than 60 days prior to the Special Mandatory Redemption Date. The Special Mandatory Redemption will occur pursuant to the procedures required by the Indenture and described in such notice.

34

The Special Mandatory Redemption Notice will set forth the date fixed for the Special Mandatory Redemption (the “Special Mandatory Redemption Date”), which date shall be the expected date of consummation of the T-Mobile Transaction, and shall be subject to the actual completion of the T-Mobile Transaction. The Special Mandatory Redemption Date may be delayed until such time as the T-Mobile Transaction is completed, and such redemption may not occur and the Special Mandatory Redemption Notice may be rescinded in the event that such condition shall not have been satisfied by the Special Mandatory Redemption Date, or by the Special Mandatory Redemption Date as so delayed, without requiring additional advance notice. In the event of such delay of the Special Mandatory Redemption Date, the amount of accrued and unpaid interest payable to (but excluding) the Special Mandatory Redemption Date will be calculated based on the Special Mandatory Redemption Date, as so adjusted. In addition, the Company may provide in the Special Mandatory Redemption Notice that payment of the Special Mandatory Redemption Price and performance of the Company’s obligations with respect to the Special Mandatory Redemption may be performed by Sprint Corporation, T-Mobile US, Inc. or any of their subsidiaries.

In any event, the Special Mandatory Redemption Date will occur no earlier than the date of the completion of the T-Mobile Transaction. Upon the termination of the Business Combination Agreement, the foregoing provisions regarding the Special Mandatory Redemption will cease to apply.

SPRINT CORPORATION, a corporation duly organized and existing under the laws of Delaware (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or registered assigns, the principal sum of [            ] MILLION DOLLARS on February 1, 2028, and to pay interest thereon from February 3, 2020, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on February 1 and August 1 of each year, commencing August 1, 2020, at the rate of 7.250% per annum, until the principal hereof is paid or made available for payment; provided that any principal and premium, and any such installment of interest, which is overdue shall bear interest at the rate of 7.250% per annum (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand. Interest will be computed on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date or the Stated Maturity of this 2028 Guaranteed Note falls on a day that is not a Business Day, the required payment shall be made on the next Business Day as if it were made on the date the payment was due and no interest shall accrue on the amount so payable for the period from and after the Interest Payment Date or the Stated Maturity of this 2028 Guaranteed Note, as the case may be, until the next Business Day. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date (or the next Business Day, as applicable) will, as provided in such Indenture, be paid to the Person in whose name this 2028 Guaranteed Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be January 15 or July 15 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date.

7.250% Guaranteed Notes Due 2028

This 2028 Guaranteed Note is one of a duly authorized issue of securities of the Company (herein called the “2028 Guaranteed Notes”), issued and to be issued in one or more series under an Indenture, dated as of September 11, 2013 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as supplemented by the Seventh Supplemental Indenture, dated as of February 3, 2020 (the “Supplemental Indenture”). Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, Sprint Communications, the Subsidiary Guarantors, the Trustee and the Holders of the 2028 Guaranteed Notes and of the terms upon which the 2028 Guaranteed Notes are, and are to be, authenticated and delivered.

In the event that the T-Mobile Transaction is consummated prior to the Stated Maturity of the 2028 Guaranteed Notes (the “Special Mandatory Redemption Event”), the Company shall redeem all of the 2028 Guaranteed Notes (the “Special Mandatory Redemption”) at a price equal to 100% of the principal amount of the 2028 Guaranteed Notes, plus accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption Date (as defined below) (such price, the “Special Mandatory Redemption Price”).

Notice of the Special Mandatory Redemption (the “Special Mandatory Redemption Notice”) shall be provided to the Trustee and to each registered Holder of the 2028 Guaranteed Notes at least three days but not more than 60 days prior to the Special Mandatory Redemption Date. The Special Mandatory Redemption will occur pursuant to the procedures required by the Indenture and described in such notice.

The Special Mandatory Redemption Notice will set forth the date fixed for the Special Mandatory Redemption (the “Special Mandatory Redemption Date”), which date shall be the expected date of consummation of the T-Mobile Transaction, and shall be subject to the actual completion of the T-Mobile Transaction. The Special Mandatory Redemption Date may be delayed until such time as the T-Mobile Transaction is completed, and such redemption may not occur and the Special Mandatory Redemption Notice may be rescinded in the event that such condition shall not have been satisfied by the Special Mandatory Redemption Date, or by the Special Mandatory Redemption Date as so delayed, without requiring additional advance notice. In the event of such delay of the Special Mandatory Redemption Date, the amount of accrued and unpaid interest payable to (but excluding) the Special Mandatory Redemption Date will be calculated based on the Special Mandatory Redemption Date, as so adjusted. In addition, the Company may provide in the Special Mandatory Redemption Notice that payment of the Special Mandatory Redemption Price and performance of the Company’s obligations with respect to the Special Mandatory Redemption may be performed by Sprint Corporation, T-Mobile US, Inc. or any of their subsidiaries.

In any event, the Special Mandatory Redemption Date will occur no earlier than the date of the completion of the T-Mobile Transaction. Upon the termination of the Business Combination Agreement, the foregoing provisions regarding the Special Mandatory Redemption will cease to apply.

(1)    100% of the principal amount of the 2028 Guaranteed Notes to be redeemed; and

(2)    the sum of the present values of the Remaining Scheduled Payments, discounted to the Redemption Date, on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the Treasury Rate, plus 50 basis points;

plus, accrued and unpaid interest, if any, to, but excluding, the applicable Redemption Date. Any calculation made pursuant to this paragraph shall not include any discounted amount with respect to the interest and principal payments due on the Stated Maturity of the 2028 Guaranteed Notes and shall instead include the discounted amount with respect to the interest and principal payments that would be payable upon redemption of the 2028 Guaranteed Notes on the First Par Call Date.

The Company may redeem the 2028 Guaranteed Notes at any time on or after the First Par Call Date, in whole or in part, at the Company’s option, at a Redemption Price equal to 100% of the principal amount of the 2028 Guaranteed Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date.

“Remaining Scheduled Payments” means with respect to each 2028 Guaranteed Note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related Redemption Date to the First Par Call Date but for such redemption; provided, that, if such Redemption Date is not an interest payment date with respect to such 2028 Guaranteed Note, the amount of the next succeeding scheduled interest payment thereon will be deemed reduced by the amount of interest accrued thereon to such Redemption Date.

“Treasury Rate” means, with respect to an applicable Redemption Date for the 2028 Guaranteed Notes: (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded United States Treasury Notes adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue; provided that if no maturity is within two months before or after the First Par Call Date, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight line basis, rounding to the nearest month; or (2) if that release, or any successor release, is not published during the week preceding the calculation date or does not contain such yields, the rate per

A-8

The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date.

On and after the Redemption Date, interest will cease to accrue on the 2028 Guaranteed Notes or any portion thereof called for redemption, unless the Company defaults in the payment of the applicable Redemption Price.

In the event of redemption of this 2028 Guaranteed Note in part only, a new 2028 Guaranteed Note or 2028 Guaranteed Notes of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

If a Change of Control Triggering Event occurs, each Holder of a 2028 Guaranteed Note will have the right to require the Company to repurchase all or any part, equal to $2,000 or an integral multiple of $1,000 thereafter, of that Holder’s 2028 Guaranteed Notes pursuant to an offer (a “Change of Control Offer”) on the terms set forth in the Supplemental Indenture.

The Company, in each Change of Control Offer, will offer a cash payment (a “Change of Control Payment”) equal to 101% of the aggregate principal amount of 2028 Guaranteed Notes repurchased, plus accrued and unpaid interest on the 2028 Guaranteed Notes, if any, to, but excluding, the date of repurchase. Within 30 days following any Change of Control Triggering Event, if the Company had not, prior to the Change of Control Triggering Event, sent a redemption notice for all the 2028 Guaranteed Notes in connection with an optional redemption permitted by the Indenture, the Company will deliver or cause to be delivered a notice to each registered Holder briefly describing the event or events that constitute a Change of Control Triggering Event and offering to repurchase 2028 Guaranteed Notes on the date specified in such notice (the “Change of Control Payment Date”), which date will be no earlier than 30 days and no later than 60 days from the date the notice is delivered, pursuant to the procedures required by the Indenture (as modified by this Supplemental Indenture) and described in such notice.

Notwithstanding the preceding two paragraphs, if the 2028 Guaranteed Notes receive an Investment Grade Rating by both of the Rating Agencies, notwithstanding that the 2028 Guaranteed Notes may later cease to have an Investment Grade Rating by either of the Rating Agencies, the Company will be released from its obligation to make a Change of Control Offer upon a Change of Control Triggering Event.

“Change of Control” means the occurrence of any of the following:

(a)    the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the Company and its Subsidiaries’ properties or assets, taken as a whole, to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than one or more Permitted Holders;
