 Ladies and Gentlemen: 

T-Mobile USA, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to
Deutsche Telekom AG (the “Purchaser”) $1,000,000,000 principal amount of its 4.500% Senior Notes due 2026-1 (the “2026 Notes”) and $1,500,000,000 principal
amount of its 4.750% Senior Notes due 2028-1 (the “2028 Notes”). The 2026 Notes and the 2028 Notes are collectively referred to herein as the “Notes”; and the
Notes together with the Guarantees (as defined below) are, together, referred to herein as the “Securities”. The Securities will be issued under the Indenture, dated as of April 28, 2013 (as previously amended, the
“Base Indenture”), and a supplemental indenture with respect to each of the 2026 Notes and the 2028 Notes, each to be dated as of the Closing Date (as defined below) and substantially containing the terms and conditions set
forth in the Description of Notes attached hereto as Exhibit A (the “Description of Notes”) to be executed in form and substance satisfactory to the parties hereto on or prior to the Closing Date (the

(“Parent”), Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), and the other Guarantors (as defined below) party thereto. 

The 2026 Notes and the 2028 Notes will have substantially the same terms and conditions as the Company’s 4.500% Senior Notes due 2026 and 4.750% Senior
Notes due 2028 (collectively, the “Public Notes”), respectively, in each case, other than issue date, issue price, registration rights and CUSIP number. In addition, each of the 2026 Notes and the 2028 Notes will be issued
under a Supplemental Indenture and will each constitute a separate series from the Public Notes for all purposes, including voting; provided that, if the Company exercises its rights in respect of a series of Public Notes, the Company will
exercise the same rights in respect of the Notes of the corresponding series on an equal and ratable basis. 
 The Notes will be sold to the Purchaser
without being registered under the Securities Act of 1933, as amended (the “Securities Act”) in reliance upon an exemption therefrom. 







 The payment of principal of, and premium and interest on, the Notes will be fully and unconditionally guaranteed
on a senior unsecured basis, jointly and severally, by (i) Parent, (ii) each of the Company’s subsidiaries listed on Schedule 1 hereto, and (iii) any subsidiary of the Company or Parent formed or acquired after the Closing Date
that executes an additional guarantee in accordance with the terms of the Indenture, and respective successors and assigns of Parent and the subsidiaries of the Company or Parent referred to in (ii) and (iii) above ((i)–(iii) collectively,
the “Guarantors”), pursuant to their guarantees (the “Guarantees”). 
 The Purchaser is entitled to the
benefits of the Stockholder’s Agreement, dated as of April 30, 2013 (the “Stockholder’s Agreement”), pursuant to which Parent has agreed to file one or more registration statements with the Securities and
Exchange Commission (the “Commission”) providing for the registration under the Securities Act of the Securities. 
 As used in this
Agreement, the term “Transaction Documents” collectively refers to this Agreement, the Indenture, the Stockholder’s Agreement and the Securities. 

1. Purchase of the Securities.

Company, subject to the conditions set forth in Sections 5 and 6 of this Agreement, agrees to issue and sell (i) the 2026 Notes in an aggregate principal amount of $1,000,000,000 and (ii) the 2028 Notes in an aggregate principal amount of
$1,500,000,000 to the Purchaser as provided in this Purchase Agreement (this “Agreement”), and the Purchaser agrees to purchase from the Company the 2026 Notes at a price equal to 100% of the principal amount thereof and the
2028 Notes at a price equal to 100% of the principal amount thereof (with the consideration therefor delivered in the form contemplated by Section 2 hereof). The Company will not be obligated to deliver any of the Notes except upon payment and
delivery of the Purchaser Exchange Notes (as defined below) for all the Notes to be purchased as provided herein.

and is purchasing the Notes in an “offshore transaction” as defined in Regulation S. 
 (ii) Restricted
Notes. The Purchaser (i) acknowledges that the issuance of the Notes has not been registered or qualified under the Securities Act or any state securities laws, and the Notes are being offered and sold in reliance upon exemptions provided
in the Securities Act and state securities laws for transactions not involving any public offering and, therefore, cannot be sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed of unless they are subsequently registered
and qualified under the Securities Act and applicable state laws or unless an exemption from such registration and qualification is available, and that the Notes will bear a legend to such effect, (ii) is purchasing the Notes without any

from the Closing Date shall be made only in accordance with Rules 903 or 904 under the Securities Act, pursuant to registration of the Securities under the Securities Act or pursuant to an available exemption from the registration requirements of
the Securities Act. The Purchaser confirms to the Company that it has 

  
 2 








 
such knowledge and experience in business matters that the Purchaser is capable of evaluating the merits and risks of an investment in the Notes and of making an informed investment decision and
understands that (x) this investment is suitable only for an investor which is able to bear the economic consequences of losing its entire investment and (y) the purchase of the Notes by the Purchaser is a speculative investment which
involves a high degree of risk of loss of the entire investment. 
 (iii) Adequate Information; No Reliance. The
Purchaser acknowledges and agrees that (i) the Purchaser has been furnished with all materials it considers relevant to making an investment decision to purchase the Notes and has had the opportunity to review the Company’s filings and
submissions with the Commission, including, without limitation, all information filed or furnished pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), (ii) the Purchaser has had a full
opportunity to ask questions of the Company concerning the Company, its business, operations, financial performance, financial condition and prospects, and the terms and conditions of the Notes, and (iii) the Purchaser has had the opportunity

that nothing in this Agreement or any other materials presented to the Purchaser in connection with the purchase and sale of the Notes constitutes legal, tax or investment advice. The Purchaser has consulted such legal, tax and investment advisors
and made such investigation as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Notes. 

(iv) No Public Market. The Purchaser understands that no public market exists for the Notes, and that there is no
assurance that a public market will ever develop for the Notes.

principal amount of the Notes in such amount (i.e., so that there is no movement of cash from the Purchaser to the Company with respect to the Purchaser’s obligations pursuant to the purchase of the Notes). On the Closing Date, the Company will
deliver to the Trustee, for the account of the Purchaser, one or more definitive certificates evidencing the 2026 Notes and the 2028 Notes.

 EXHIBIT A 

DESCRIPTION OF NOTES 

Attached. 







 DESCRIPTION OF NOTES 

You can find the definitions of certain terms used in this description of notes under the caption “—Certain Definitions” below.
In this description of notes, “Issuer” refers only to T-Mobile USA, Inc., a Delaware corporation, and not to any of its Subsidiaries, and “Parent” refers only to T-Mobile US, Inc., a Delaware corporation and the
direct parent company of Issuer, and not to any of its Subsidiaries. 
 Issuer will issue $2,500,000,000 in aggregate principal amount of
notes in this offering as two separate series: $1,000,000,000 in aggregate principal amount of notes due 2026 (the “2026 notes”) and $1,500,000,000 in aggregate principal amount of notes due 2028 (the “2028
notes” and together with the 2026 notes, the “notes”). 
 Issuer will issue the notes under that certain base
indenture (the “base indenture”) among itself, Parent, the Subsidiary Guarantors and Deutsche Bank Trust Company Americas, as trustee (the “trustee”), dated April 28, 2013, as supplemented with respect to each
series of notes, by a supplemental indenture (for each such series, the “supplemental indenture”) among Issuer, Parent, the Subsidiary Guarantors and the trustee. In this description of notes, the term “indenture”
refers to the base indenture as supplemented separately by the supplemental indenture for each series of notes. The terms of the notes of each series include those stated in the indenture and those made part of the indenture by reference to the
Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). 
 The obligations and covenants of Issuer described
hereunder are only of Issuer and not of Parent. Although Parent is a guarantor of the notes, it and its Subsidiaries, except Issuer and its Restricted Subsidiaries, are generally not subject to any of the obligations and covenants described
hereunder. 
 The following description is a summary of the material provisions of the indenture. It does not restate the indenture in its
entirety. We urge you to read the indenture in its entirety because it, and not this description of notes, defines your rights as a holder of the notes. For more information on how you can obtain a copy of the base indenture and supplemental
indenture, see “Where You Can Find More Information.” Certain defined terms used in this description of notes but not defined below under “—Certain Definitions” have the meanings assigned to them in the indenture. 

The registered holder of a note will be treated as the owner of the note for all purposes. Only registered holders will have rights under the
indenture. 
 Brief Description of the Notes and the Note Guarantees 

The Notes 
 The notes of each series: 

 

	 	•	 	will be general unsecured, unsubordinated obligations of Issuer; 

  

	 	•	 	will be senior in right of payment to any future Indebtedness of Issuer to the extent that such future Indebtedness provides by its terms that it is subordinated to the notes; 


 

	 	•	 	will be equal in right of payment with any of Issuer’s existing and future Indebtedness and other liabilities that are not by their terms subordinated in right of payment to the notes, including, without
limitation, borrowings under the Revolving Credit Facilities and the Term Loan Credit Agreement (including the Incremental Term Loan Facility) and the Existing Senior Notes; 


 

	 	•	 	will be effectively subordinated to Issuer’s existing and future secured Indebtedness, including borrowings under the Secured Revolving Credit Facility and the Term Loan Credit Agreement (including the Incremental
Term Loan Facility) to the extent of the value of Issuer’s assets constituting collateral securing such Indebtedness; 


  
 A-1 









	 	•	 	will be structurally subordinated to all of the liabilities and any future preferred stock of Issuer’s non-guarantor subsidiaries; and 


 

	 	•	 	will be unconditionally guaranteed on a senior unsecured basis by the Guarantors. 

 See
“Risk Factors—Risks Related to the Notes—The notes and the guarantees will be unsecured and effectively subordinated to Issuer’s and the guarantors’ existing and future secured indebtedness, including borrowings under the
Term Loan Credit Agreement and the Secured Revolving Credit Facility, and structurally subordinated to the indebtedness and other liabilities of Issuer’s non-guarantor subsidiaries.” 

Assuming that on September 30, 2017, we had completed the January 2018 Notes Redemption, effected the Revolver Borrowing, completed the
offering of the notes and used the proceeds thereof as anticipated, we would have had approximately $31.0 billion of outstanding indebtedness, including $21.6 billion of outstanding indebtedness under the Issuer’s Existing Senior Notes and the
notes offered hereby, $4.0 billion of outstanding secured indebtedness under the Term Loan Credit Agreement, $1.0 billion of outstanding secured indebtedness under the Secured Revolving Credit Facility and approximately $2.6 billion in tower
obligations relating to the Tower Transactions. We also would have had $0.5 billion available for borrowing under the Secured Revolving Credit Facility and $1.0 billion available for borrowing under the Unsecured Revolving Credit Facility. 

As of September 30, 2017, Issuer’s Subsidiaries that will not guarantee the notes that were included in Parent’s consolidated
financial statements as of such date had approximately $1.5 billion of total assets (excluding receivables due from Issuer and its guarantor Subsidiaries) and $2.6 billion in Indebtedness, other liabilities and preferred stock (excluding payables
due to Issuer and its guarantor subsidiaries). 
 The Note Guarantees 

The notes will be guaranteed by Parent, all of Issuer’s Domestic Restricted Subsidiaries that are Wholly-Owned Subsidiaries (other than
Designated Tower Entities, Immaterial Subsidiaries and the Reinsurance Entity), Issuer’s Restricted Subsidiaries that guarantee any Specified Issuer Indebtedness, and any future Subsidiary of Parent that directly or indirectly owns equity
interests of Issuer. These Note Guarantees will be joint and several obligations of the Guarantors. The obligations of each Guarantor under its Note Guarantee will be limited as necessary to prevent that Note Guarantee from constituting a fraudulent
conveyance under applicable law. See “Risk Factors—Risks Related to the Notes—The guarantees may not be enforceable because of fraudulent conveyance laws.” 

Each guarantee of the notes by a Guarantor: 
  

	 	•	 	will be a general unsecured, unsubordinated obligation of that Guarantor; 

  

	 	•	 	will be senior in right of payment to any future Indebtedness of that Guarantor to the extent that such future Indebtedness provides by its terms that it is subordinated in right of payment to such Guarantor’s
guarantee of the notes; 

  

	 	•	 	will be equal in right of payment with all existing and future Indebtedness and other liabilities of that Guarantor that are not by their terms subordinated to its guarantee of the notes, including, without limitation,
any guarantees of the borrowings under the Revolving Credit Facilities and the Term Loan Credit Agreement (including the Incremental Term Loan Facility) and Issuer’s Existing Senior Notes; 


 

	 	•	 	will be effectively subordinated to that Guarantor’s existing and future secured Indebtedness, including its guarantee of the borrowings under the Secured Revolving Credit Facility and the Term Loan Credit
Agreement (including the Incremental Term Loan Facility) to the extent of the value of the assets of such Guarantor constituting collateral securing that Indebtedness; and 


 

	 	•	 	will be structurally subordinated to all of the Indebtedness and other liabilities and any future preferred stock of any subsidiaries of such Guarantor that do not guarantee the notes. 


  
 A-2 








 See “Risk Factors—Risks Related to the Notes—The notes and the guarantees will be
unsecured and effectively subordinated to Issuer’s and the guarantors’ existing and future secured indebtedness, including the Incremental Term Loan Facility and borrowings under the Secured Revolving Credit Facility and Term Loan Credit
Agreement, and structurally subordinated to the indebtedness and other liabilities of Issuer’s non-guarantor subsidiaries.” 

Under the circumstances described below under the subheading “—Certain Covenants—Additional Note Guarantees,” one or more
of Issuer’s Subsidiaries (including Issuer’s existing Domestic Restricted Subsidiaries) together with certain newly created or acquired Subsidiaries in the future may not guarantee the notes. In the event of a bankruptcy, liquidation or
reorganization of any of these non-guarantor Subsidiaries, the non-guarantor Subsidiaries will pay their trade creditors and holders of their debt and other obligations before they will be able to distribute any of their assets to Issuer. 

As of the Series Issue Date, all of Issuer’s Subsidiaries other than the Layer3 Entities (if applicable) will be “Restricted
Subsidiaries.” However, under the circumstances described below under the caption “—Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries,” Issuer will be permitted to designate certain of its
Subsidiaries as “Unrestricted Subsidiaries.” Issuer’s Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the indenture. Issuer’s Unrestricted Subsidiaries will not guarantee the notes. 

Except as otherwise provided in the following paragraph, a Guarantor of the notes of any series (other than Parent) may not sell or otherwise
dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than Issuer or another Guarantor, unless: 

 

	(1)	immediately after giving effect to that transaction, no Default or Event of Default exists in respect of the notes of such series; and 


 

	(2)	either: 

  

	 	(a)	subject to the following paragraph and if it is not already a Guarantor of the notes of such series, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such
consolidation or merger assumes all the obligations of that Guarantor under the indenture and its Note Guarantee of the notes of such series pursuant to a supplemental indenture; or 


 

	 	(b)	such sale or other disposition complies with the “Asset Sale” provisions of the indenture (it being understood that only such portion of the Net Proceeds as is or is required to be applied on or before the
date of such release in accordance with the terms of the indenture needs to be so applied). 

 The Note Guarantee of a
Guarantor will be released in respect of the notes of any series: 
  

	(1)	only in the case of a Subsidiary Guarantor, in connection with any sale or other disposition of all or substantially all of the assets of that Subsidiary Guarantor (including by way of merger or consolidation) to a
Person that is not (either before or after giving effect to such transaction) Issuer or a Restricted Subsidiary of Issuer, if the sale or other disposition is not prohibited by the “Asset Sale” provisions of the indenture;


  

	(2)	only in the case of a Subsidiary Guarantor, in connection with any issuance, sale or other disposition of Capital Stock of that Subsidiary Guarantor to a Person that is not (either before or after giving effect to such
transaction) Issuer or a Restricted Subsidiary of Issuer, if the issuance, sale or other disposition does not violate the “Asset Sale” or “Restricted Investment” provisions of the indenture, and the Subsidiary Guarantor ceases to
be a Wholly-Owned Subsidiary of Issuer as a result of such sale or other disposition and does not guarantee any Specified Issuer Indebtedness; 

  

	(3)	if such Guarantor (other than Parent) ceases to guarantee any Specified Issuer Indebtedness and such Guarantor would not otherwise be required to guarantee the series of notes pursuant to the covenant described below
under the caption “—Certain Covenants—Additional Note Guarantees”; 


  
 A-3 









	(4)	if Issuer designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of the indenture; 


 

	(5)	upon the legal defeasance, covenant defeasance, or satisfaction and discharge of the indenture as provided below under the captions “—Legal Defeasance and Covenant Defeasance” and “—Satisfaction
and Discharge”; 

  

	(6)	upon the liquidation or dissolution of such Guarantor (other than Parent) provided no Default or Event of Default has occurred that is continuing; or 


 

	(7)	if such Guarantor becomes an Immaterial Subsidiary and such Guarantor would not otherwise be required to guarantee the series of notes pursuant to the covenant described below under the caption “—Certain
Covenants—Additional Note Guarantees.” 

 See “—Repurchase at the Option of Holders—Asset Sales”
below. 
 Principal, Maturity and Interest 

After the completion of the January 2018 Notes Redemption and this offering, and reflecting the anticipated use of proceeds thereof, Issuer
would have outstanding $21.6 billion in aggregate principal amount of senior notes. 
 Issuer will issue $2,500,000,000 in aggregate
principal amount of notes in this offering, of which $1,000,000,000 in aggregate principal amount will be 2026 notes and $1,500,000,000 in aggregate principal amount will be 2028 notes. 

Issuer may issue further additional notes of any series from time to time, and such additional notes of such series may be issued under the
base indenture as supplemented either by the supplemental indenture for such series of notes or one or more other supplemental indentures. Any issuance of additional notes is subject to all of the covenants in the indenture, including the covenant
described below under the caption “—Certain Covenants—Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock.” The notes of any series and any additional notes of such series subsequently issued will be
treated as a single series for all purposes under the indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. 

Issuer will issue notes in minimum denominations of $2,000 and integral multiples of $1,000. The 2026 notes will mature on February 1,
2026 and the 2028 notes will mature on February 1, 2028. 
 Interest on the 2026 notes will accrue at the rate of 4.500% per annum and
interest on the 2028 notes will accrue at the rate of 4.750% per annum, and interest on each series of notes will be payable semiannually in arrears on February 1 and August 1, commencing on August 1, 2018. Issuer will make each
interest payment to the holders of record on the immediately preceding January 15 and July 15. 
 Interest on the notes will
accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. If an interest payment date or the
maturity date falls on a day that is not a Business Day, the related payment of principal or interest will be made on the next succeeding Business Day as if made on the date the payment was due, and no interest shall accrue for the intervening
period. 
 Payments of principal of and interest on the notes issued in book-entry form or definitive form, if any, will be made as
described below under the caption “—Methods of Receiving Payments on the Notes.” 
 Each series of notes initially will be
evidenced by one or more global notes deposited with a custodian for, and registered in the name of, Cede & Co., as nominee of The Depository Trust Company (“DTC”). Except as 

  
 A-4 








 
described below, beneficial interests in the global notes will be shown on, and transfers thereof will be effected only through, records maintained by DTC and its direct and indirect
participants. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system. 

Methods of Receiving Payments on the Notes 

If a holder of a definitive note has given wire transfer instructions to Issuer and Issuer is the paying agent, Issuer will pay all principal,
interest and premium, if any, on that holder’s notes in accordance with those instructions until given written notice to the contrary. All other payments on the notes will be made at the Corporate Trust Office of the Trustee, unless Issuer
elects to make interest payments by check mailed to the noteholders at their address set forth in the books and records of the registrar. 
 Paying Agent
and Registrar for the Notes 
 The trustee will initially act as paying agent and registrar. Issuer may change the paying agent or
registrar without prior notice to the holders of the notes, and Issuer or any of its Subsidiaries may act as paying agent or registrar. 
 Transfer and
Exchange 
 Except as set forth below, the global notes may be transferred, in whole and not in part, only to another nominee of DTC or
to a successor of DTC or its nominee. 
 A holder of a definitive note may transfer or exchange notes in accordance with the provisions of
the indenture. The registrar and the trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. Holders will be required to pay all taxes relating to, arising
out of, or in connection with such transfer. Issuer will not be required to transfer or exchange any note selected for redemption. Also, Issuer will not be required to transfer or exchange any note for a period of 15 days before a selection of notes
to be redeemed.

 Mandatory Redemption 

Issuer is not required to make mandatory redemption or sinking fund payments with respect to the notes. 

Repurchase at the Option of Holders 

Change of Control Triggering Event 

If a Change of Control Triggering Event occurs with respect to any series of notes, each holder of notes of such series will have the right to
require Issuer to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000) of that holder’s notes of such series pursuant to a Change of Control Offer on the terms set forth in the indenture. In the Change of Control
Offer, Issuer will offer a Change of Control Payment in cash equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest, if any, on the notes repurchased to, but not including, the date of purchase, subject
to the rights of holders of notes on the relevant record date to receive interest due on the relevant interest payment date for periods prior to such repurchase date (the “Change of Control Payment”). Within 30 days following any
Change of Control Triggering Event, Issuer will send a notice (the “Change of Control Offer”) to each holder of notes to which such Change of Control Triggering Event applies and the trustee describing the transaction or
transactions and identify the ratings decline that together constitute the Change of Control Triggering Event and offering to repurchase the notes of such series on the Change of Control Payment Date specified in the notice, which date will be no
earlier than 10 days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”), pursuant to the procedures required by the indenture and described in such notice. Issuer will comply with the
requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the
repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the indenture, or compliance with
the Change of Control Triggering Event provisions of the indenture would constitute a violation of any such laws or regulations, Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its
obligations under the Change of Control Triggering Event provisions of the indenture by virtue of such compliance. In connection with the tender of any notes with respect to a Change of Control Triggering Event, the tendering holder shall provide
good title to the notes, free and clear of all liens and encumbrances, and shall represent and warrant that such holder is presenting good title, free and clear of all liens and encumbrances, and such other representations and warranties as are
customary. 
 On the Change of Control Payment Date, Issuer will, to the extent lawful: 

 

	(1)	accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer; 

  

	(2)	deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered; and 


 

	(3)	deliver or cause to be delivered to the paying agent the notes properly accepted together with an officers’ certificate stating the aggregate principal amount of notes or portions of notes being purchased by
Issuer. 


  
 A-7 








 The paying agent will promptly make payment, to each holder of notes properly tendered, of the
Change of Control Payment for such notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder, a new note equal in principal amount to any unpurchased portion of the notes surrendered, if
any; provided that each new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date. 
 The provisions described above that require Issuer to make a Change of Control Offer following a Change
of Control Triggering Event will be applicable whether or not any other provisions of the indenture are applicable. Except as described above with respect to a Change of Control Triggering Event, the indenture does not contain provisions that permit
the holders of the notes to require, or otherwise provide, that Issuer repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction. 

Notwithstanding the foregoing, Issuer will not be required to make a Change of Control Offer with respect to any series of the notes upon a
Change of Control Triggering Event if (1) a third party makes the Change of Control Offer for such series of notes in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to a Change
of Control Offer made by Issuer and purchases all notes of such series properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption with respect to such series has been given pursuant to the indenture as
described above under the caption “—Optional Redemption,” unless and until there is a default in payment of the applicable redemption price. 

A Change of Control Offer may be made in advance of a Change of Control Triggering Event, and conditioned upon such Change of Control
Triggering Event, if a definitive agreement has been executed for a transaction that would constitute a Change of Control at the time of making of the Change of Control Offer. 

In the event that holders of not less than 90% of the aggregate principal amount of the outstanding notes of a series accept a Change of
Control Offer and Issuer purchases all of the notes of such series held by such holders, Issuer will have the right, upon not less than 10 nor more than 60 days’ notice, given not more than 30 days following the purchase pursuant to the Change
of Control Offer described above, to redeem all of the notes of such series that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control
Payment, accrued and unpaid interest, if any, on the notes of such series that remain outstanding, to, but not including, the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on an
interest payment date that is on or prior to the redemption date). 
 The definition of Change of Control includes a phrase relating to the
direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of Issuer and its Restricted Subsidiaries taken as a whole. Although there is a limited body of case law
interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of notes to require Issuer to repurchase its notes as a result of a sale,
lease, transfer, conveyance or other disposition of less than all of the assets of Issuer and its Restricted Subsidiaries taken as a whole to another Person or group may be uncertain. 

Asset Sales 

Issuer will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 

 

	(1)	Issuer (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise
disposed of; and 


  
 A-8 









	(2)	at least 75% of the consideration received by Issuer or such Restricted Subsidiary in the Asset Sale and all other Asset Sales since the Closing Date is in the form of cash, Cash Equivalents or Replacement Assets or a
combination thereof. For purposes of this provision, each of the following will be deemed to be cash: 

  

	 	(a)	any liabilities, as shown on Issuer’s most recent consolidated balance sheet (or as would be shown on Issuer’s consolidated balance sheet as of the date of such Asset Sale), of Issuer or any Restricted
Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the notes or any Note Guarantees) that are assumed by the transferee of any such assets pursuant to a novation agreement that releases Issuer or
such Restricted Subsidiary from further liability; 

  

	 	(b)	any securities, notes or other obligations received by Issuer, or any such Restricted Subsidiary, from such transferee that are converted by Issuer or such Restricted Subsidiary into cash, Cash Equivalents or
Replacement Assets within 90 days after such Asset Sale, to the extent of the cash, Cash Equivalents or Replacement Assets received in that conversion; 

  

	 	(c)	consideration consisting of Indebtedness of Issuer or a Restricted Subsidiary (other than Subordinated Indebtedness) received after the Series Issue Date from Persons who are not Issuer or any Restricted Subsidiary; and


  

	 	(d)	any Designated Non-cash Consideration received by Issuer or any Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value (as determined in good faith by Issuer), taken together with all other
Designated Non-cash Consideration received pursuant to this clause (d) that is at any time outstanding, not to exceed 5% of Issuer’s Total Assets (with the Fair Market Value of each item of Designated Non-cash Consideration being measured
at the time received and without giving effect to subsequent changes in value). 

 Notwithstanding the foregoing, the 75%
limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash, Cash Equivalents or Replacement Assets portion of the consideration received therefrom, determined in accordance with the foregoing provision on
an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation. 

Within 365 days after the receipt of any Net Proceeds from an Asset Sale, Issuer or a Restricted Subsidiary may apply an amount equal to such
Net Proceeds: 
  

	(1)	to purchase Replacement Assets; 

  

	(2)	to prepay, repay, defease, redeem, purchase or otherwise retire Indebtedness and other Obligations under a Credit Facility or Indebtedness secured by property that is subject to such Asset Sale and, if the Indebtedness
repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto; 

  

	(3)	to prepay, repay, defease, redeem, purchase or otherwise retire Obligations under Indebtedness that is not Subordinated Indebtedness other than the Indebtedness described in clause (2) above (and, if the
Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto); provided that Issuer shall equally and ratably prepay, repay, defease, redeem, purchase or otherwise retire (or offer to
prepay, repay, defease, redeem, purchase or otherwise retire, as applicable) Obligations under the notes on a pro rata basis for no less than 100% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to, but not
including, the applicable redemption date; or 

  

	(4)	if the assets subject to such Asset Sale are the property or assets of a Restricted Subsidiary that is not a Guarantor, to prepay, repay, defease, redeem, purchase or otherwise retire Indebtedness of such Restricted
Subsidiary or Indebtedness of any other Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to Issuer or any Restricted Subsidiary. 


Notwithstanding the foregoing, if within 365 days after the receipt of any Net Proceeds from an Asset Sale, Issuer or a Restricted Subsidiary
enters into a binding written agreement committing Issuer or such Restricted 

  
 A-9 








 
Subsidiary, subject to customary conditions, to an application of funds of the kind described in clause (1) above, Issuer or such Restricted Subsidiary shall be deemed not to be in violation
of the preceding paragraph so long as such application of funds is consummated within 545 days of the receipt of such Net Proceeds. 

Pending the final application of any Net Proceeds of an Asset Sale, Issuer may temporarily reduce revolving credit borrowings or otherwise use
the Net Proceeds in any manner that is not prohibited by the indenture. 
 An amount equal to any Net Proceeds from Asset Sales that are not
applied or invested as provided in the third paragraph of this covenant will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $100.0 million, within 20 days thereof, Issuer shall apply the entire
aggregate amount of unutilized Excess Proceeds (not only the amount in excess of $100.0 million) to make an offer (an “Asset Sale Offer”) to all holders of notes and all holders of other Indebtedness that is pari passu with
the notes containing provisions requiring Issuer to make an offer to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of notes and purchase or redeem such other pari passu Indebtedness that may
be purchased or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount of the notes and such other pari passu Indebtedness that may be purchased or redeemed with Excess
Proceeds, plus accrued and unpaid interest, if any, to, but not including, the date of consummation of the purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Issuer and its Restricted
Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by the indenture. If the aggregate principal amount of notes and other pari passu Indebtedness tendered in response to such Asset Sale Offer exceeds the
amount of Excess Proceeds, the trustee shall select the notes and Issuer will select such other pari passu Indebtedness to be purchased or redeemed on a pro rata basis unless otherwise required by law or applicable stock exchange or
depositary requirements. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 Issuer will
comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of notes pursuant to an Asset Sale
Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of the indenture, or compliance with the Asset Sale provisions of the indenture would constitute a violation of any such laws or
regulations, Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of the indenture by virtue of such compliance. 

The agreements governing Issuer’s other Indebtedness contain, and future agreements may contain, prohibitions of certain events,
including events that would constitute a Change of Control or an Asset Sale and may prohibit repurchases of or other prepayments in respect of the notes. The exercise by the holders of the notes of their right to require Issuer to repurchase the
notes upon a Change of Control Triggering Event or an Asset Sale could cause a default under these other agreements, even if the Change of Control Triggering Event or Asset Sale itself does not, due to the financial effect of such repurchases or
other prepayments on Issuer. In the event a Change of Control Triggering Event or Asset Sale occurs at a time when Issuer is prohibited from purchasing notes, Issuer could seek the consent of the holders of such Indebtedness to the purchase of notes
or could attempt to refinance the borrowings that contain such prohibition. If Issuer does not obtain a consent or repay those borrowings, Issuer will remain prohibited from purchasing notes. In that case, Issuer’s failure to purchase tendered
notes would constitute an Event of Default under the applicable indenture that could, in turn, constitute a default under the other Indebtedness. Finally, Issuer’s ability to pay cash to the holders of notes upon a repurchase may be limited by
Issuer’s then existing financial resources. See “Risk Factors—Risks Related to the Notes—The indenture governing the Existing Senior Notes and the notes offered hereby, our Revolving Credit Facilities and the Term Loan Credit
Agreement include or will include restrictive covenants that limit our operating flexibility.” 

  
 A-10 








 Selection and Notice 

If less than all of the notes of a series are to be redeemed, the trustee will select notes of such series for redemption on a pro rata
basis unless otherwise required by law or applicable stock exchange or depositary requirements. 
 No notes of $2,000 or less can be
redeemed in part. Notices of redemption will be sent electronically or mailed by first class mail at least 10 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address, except that
redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the notes of a series or a satisfaction and discharge of the indenture with respect to such series. Except as
otherwise set forth in the provisions described under the caption “—Repurchase at the Option of Holders—Change of Control Triggering Event,” any such notice of redemption may, at Issuer’s discretion, state that such
redemption is subject to one or more conditions precedent. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in Issuer’s discretion, the redemption date may
be delayed until such time as any or all such conditions shall be satisfied (or waived by Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have
been satisfied (or waived by Issuer in its sole discretion) by the redemption date (whether the original redemption date or the redemption date so delayed). 

If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount
of that note that is to be redeemed. If in definitive form a new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the holder of notes upon cancellation of the original note. Except to the
extent that a notice of redemption is conditional as permitted in the provisions described under the caption “—Repurchase at the Option of Holders—Change of Control Triggering Event,” notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to accrue on notes or portions of notes called for redemption. 
 Certain
Covenants 
 Changes in Covenants When Notes Rated Investment Grade 

If on any date following the Series Issue Date with respect to a series of notes: 

 

	(1)	the notes of such series are rated Investment Grade by two out of the three Rating Agencies; and 

  

	(2)	no Default or Event of Default shall have occurred and be continuing with respect to the notes of such series (other than with respect to the covenants specifically listed under the following captions),


 then, beginning on that day, the covenants specifically listed under the following captions in this prospectus supplement will cease to
apply to such series of notes and will not be later reinstated even if the ratings of the notes of such series should subsequently decline: 
  

	(1)	“—Repurchase at the Option of Holders—Asset Sales”; 

  

	(2)	“—Restricted Payments”; 

  

	(3)	“—Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock”; 

  

	(4)	“—Dividend and Other Payment Restrictions Affecting Subsidiaries”; 

  

	(5)	“—Transactions with Affiliates”; 

  

	(6)	“—Designation of Restricted and Unrestricted Subsidiaries”; and 

  

	(7)	clauses (3) (to the extent that a Default or Event of Default exists by reason of one or more of the covenants specifically listed in this paragraph) and (4) of the covenant described below under the caption
“—Merger, Consolidation or Sale of Assets.” 

 There can be no assurance that the notes of any series will ever
achieve an Investment Grade rating. 

  
 A-11 








 Restricted Payments 

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: 

 

	(1)	declare or pay (without duplication) any dividend, or make any other payment or distribution, on account of Issuer’s or any of its Restricted Subsidiaries’ Equity Interests (including any payment in connection
with any merger or consolidation involving Issuer or any of its Restricted Subsidiaries) or to the direct or indirect holders of Issuer’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than
dividends or distributions payable in Equity Interests (other than Disqualified Stock) of Issuer and other than dividends or distributions payable to Issuer or a Restricted Subsidiary of Issuer); 


 

	(2)	purchase, redeem or otherwise acquire or retire for value (including in connection with any merger or consolidation involving Issuer) any Equity Interests of Issuer or any direct or indirect parent of Issuer;


  

	(3)	make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Subordinated Indebtedness (excluding any intercompany Indebtedness between or among Issuer and any of its
Restricted Subsidiaries), except a payment of interest or principal at the Stated Maturity thereof; or 

  

	(4)	make any Restricted Investment (all such payments and other actions set forth in clauses (1) through (4) above being collectively referred as “Restricted Payments”), 


unless, at the time of and after giving effect to such Restricted Payment: 
  

	(a)	no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; 

  

	(b)	Issuer would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to
incur at least $1.00 of additional Indebtedness pursuant to the Debt to Cash Flow Ratio test set forth in the first paragraph of the covenant described below under the caption “—Incurrence of Indebtedness and Issuance of Disqualified Stock
and Preferred Stock”; and 

  

	(c)	such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by Issuer and its Restricted Subsidiaries since the Closing Date (excluding Restricted Payments permitted by clauses (2),
(3), (4), (5), (6), (7), (8), (9), (11), (12), (13), (14), (15), (16) and (17) of the next succeeding paragraph), is less than the sum, without duplication, of: 


 

	 	(i)	100% of Issuer’s Consolidated Cash Flow for the period (taken as one accounting period) from and after the Closing Date to the end of Issuer’s most recently ended fiscal quarter for which internal financial
statements are available at the time of such Restricted Payment, less the product of 1.4 times Issuer’s Consolidated Interest Expense for the same period; plus 


 

	 	(ii)	100% of the aggregate net cash proceeds, and the Fair Market Value of any property other than cash, in each case received by Issuer after the Closing Date as a contribution to its common equity capital (other than any
such contribution resulting, or deemed to result, from the Merger) or from the issue or sale of Equity Interests of Issuer (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or
exchangeable debt securities of Issuer that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of Issuer); plus 


 

	 	(iii)	to the extent that any Restricted Investment that was made after the Closing Date, or, that any Restricted Investment that was made by MetroPCS Wireless, Inc. or any of its Restricted Subsidiaries after November 3,
2006 and prior to the Closing Date (provided that, and solely to the extent that, such Restricted Investment, at the time made, reduced the amount that would be calculated pursuant to clause (g) below), in each case, is sold for cash or
Cash Equivalents, or otherwise is liquidated or repaid for cash or Cash Equivalents, an amount equal to such cash and Cash Equivalents; plus 


  
 A-12 









	 	(iv)	to the extent that any Unrestricted Subsidiary of Issuer designated as such after the Closing Date is redesignated as a Restricted Subsidiary after the Closing Date, the Fair Market Value of Issuer’s Investment in
such Subsidiary as of the date of such redesignation; other than to the extent such Investment constituted a Permitted Investment; plus 

  

	 	(v)	100% of any cash dividends or cash distributions, and the Fair Market Value of any property other than cash, in each case actually received directly or indirectly by Issuer or a Restricted Subsidiary of Issuer that is a
Guarantor after the Closing Date from an Unrestricted Subsidiary of Issuer, in each case, to the extent that such dividends, cash distributions or other property were not otherwise included in the Consolidated Net Income of Issuer for such period
and other than to the extent such Investment constituted a Permitted Investment; minus 

  

	 	(vi)	the aggregate amount of any Net Equity Proceeds taken into account for purposes of incurring Indebtedness pursuant to clause (14) the definition of “Permitted Debt” set forth below under the caption
“—Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock,” after the Closing Date; plus 

  

	 	(vii)	the amount that would be calculated immediately prior to the consummation of the Merger on the Closing Date pursuant to clause (3) of the second paragraph of Section 4.07(a) of the September 2010 Senior Notes
Indenture, as in effect immediately prior to the effectiveness of the December 2012 Sixth Supplemental Indenture (provided that any calculation of cumulative Consolidated Cash Flow and Consolidated Interest Expense in subclause (A) of
such clause (3) shall include (x) Issuer’s last fiscal quarter ending prior to the Closing Date, and (y) the period from the beginning of Issuer’s fiscal quarter during which the Closing Date occurs to the Closing Date, in
each case, if internal financial statements are available for such period at the time of calculation, even if they are not available immediately prior to the consummation of the Merger on the Closing Date). 


As of September 30, 2017, the amount calculated pursuant to clause (c)(i)-(vii) above (the “RP Basket”), was
approximately $33 billion. 
 The preceding provisions will not prohibit: 

 

	(1)	the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or giving of the redemption notice, as the case may be, if at the date of
declaration or notice, the dividend or redemption payment would have complied with the provisions of the indenture;

Stock) or from the substantially concurrent contribution of common equity capital to Issuer; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (3)(b) of
the preceding paragraph; provided, further, that any Net Equity Proceeds (x) used for making a Restricted Investment pursuant to clause (10) of this paragraph or (y) taken into account for purposes of incurring
Indebtedness pursuant to clause (14) of the definition of “Permitted Debt” set forth below under the caption “—Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock,” may not also be used to
make a Restricted Payment pursuant to this clause (2); 

  

	(3)	the repurchase, redemption, defeasance or other acquisition or retirement for value of Subordinated Indebtedness of Issuer or any Subsidiary Guarantor with the net cash proceeds from a substantially concurrent

agreement or similar agreement; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed an amount equal to $50.0 million in any fiscal year; provided,
further, that such amount in any fiscal year may be increased by an amount equal to (a) the net cash proceeds contributed to Issuer from the sale of Equity Interests of Parent to current or former members of management, directors,

Restricted Payment would be equal to or less than 3.00 to 1.00; 

 provided, however, that at the time of, and after giving effect to,
any Restricted Payment permitted under clauses (16) or (17), no Default or Event of Default has occurred and is continuing or would be caused thereby. 

For purposes of determining compliance with this “Restricted Payments” covenant, in the event that an Investment or Restricted
Payment meets the criteria of more than one of the categories described in clauses (1) through (17) above or one or more of the exceptions contained in the definition of “Permitted Investments”, Issuer will be permitted to
classify all or a portion of such Investment or Restricted Payment on the date of its occurrence, or later reclassify all or a portion of such Investment or Restricted Payment, in any manner that complies with this covenant. 

The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by Issuer or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. 

Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock 

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or
otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and Issuer will not issue any Disqualified Stock and will not permit any
of its Restricted Subsidiaries to issue any shares of Preferred Stock; provided, however, that Issuer may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock and the Subsidiary Guarantors may incur Indebtedness
(including Acquired Debt) or issue Preferred Stock, if the Debt to Cash Flow Ratio for Issuer’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock or such Preferred Stock is issued, as the case may be, would have been no greater than 6.00 to 1.00, determined on a pro forma basis (including a pro forma application of the net
proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the Preferred Stock had been issued, as the case may be, at the beginning of such four-quarter period. 

The first paragraph of this covenant will not prohibit the incurrence of any of the following items of Indebtedness (collectively,
“Permitted Debt”), nor will it prohibit Issuer from issuing the following types of Disqualified Stock or Issuer’s Restricted Subsidiaries from issuing the following types of Preferred Stock: 

 

	(1)	 the incurrence by Issuer and any Subsidiary Guarantor of (a) additional Indebtedness under Credit
Facilities, provided that giving effect to such incurrence, the aggregate principal amount (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of Issuer and its Restricted Subsidiaries
thereunder) of all Indebtedness under Credit Facilities then outstanding under this paragraph (1), together with any Indebtedness incurred pursuant to the following clause (b), does not exceed the greater of (x) $9.0 billion and (y) an
amount such that, upon the incurrence of Indebtedness under this clause (1), the Secured Debt to Cash Flow Ratio of Issuer and its Subsidiaries for the most recently ended four full fiscal quarters for which financial statements are available,
calculated on a pro forma basis in the manner described in the definition of “Secured Debt to Cash Flow Ratio,” shall not exceed 2.00:1.00; provided that for purposes of determining the amount of Indebtedness that may be incurred
under this clause (a)(y), all Indebtedness incurred under this clause (1) shall be treated as Consolidated Indebtedness that is secured by a Lien and (b) without duplication, all Indebtedness incurred to renew, refund, refinance, replace,
defease or discharge any Indebtedness incurred pursuant to the foregoing clause (a); provided, however, that the 



  
 A-15 









	 	
maximum amount permitted under this clause (1) shall not be deemed to limit additional Indebtedness under the Credit Facilities to the extent that the incurrence of such additional
Indebtedness is permitted pursuant to any of the other provisions of this covenant; 

  

	(2)	the incurrence by Issuer and its Restricted Subsidiaries of any Existing Indebtedness or any Series Issue Date Existing Indebtedness; 


 

	(3)	the incurrence by Issuer and the Subsidiary Guarantors of Indebtedness represented by the notes to be issued on the date of the supplemental indentures and the related Note Guarantees; 


 

	(4)	the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of
financing (whether prior to or within 270 days after) all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment or the Capital Stock of any Person owning such assets used in
the business of Issuer or any of its Restricted Subsidiaries, in an aggregate principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any
Indebtedness incurred pursuant to this clause (4); 

  

	(5)	the incurrence by Issuer or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any
Indebtedness (other than intercompany Indebtedness) that was permitted by the indenture to be incurred under the first paragraph of this covenant or clauses (2), (3), (4), (5), (13), (14), (15), (24) or (25) of this paragraph;


  

	(6)	the incurrence by Issuer or any of its Restricted Subsidiaries of intercompany Indebtedness between or among Parent, Issuer and any of its Restricted Subsidiaries and any Guarantors; provided, however,
that: 

  

	 	(a)	if Issuer or any Subsidiary Guarantor is the obligor on such Indebtedness and the payee is not Issuer or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all
Obligations then due with respect to the notes, in the case of Issuer, or the Note Guarantee, in the case of a Subsidiary Guarantor; and 

  

	 	(b)	(i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than Parent, Issuer or a Restricted Subsidiary of Issuer, or a Guarantor and (ii) any
sale or other transfer of any such Indebtedness to a Person that is not either Parent, Issuer or a Restricted Subsidiary of Issuer, or a Guarantor, will be deemed, in each case, to constitute an incurrence of such Indebtedness by Issuer or such
Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 

  

	(7)	the issuance by any of Issuer’s Restricted Subsidiaries to Issuer or to any of its Restricted Subsidiaries of shares of Preferred Stock; provided, however, that: 


 

	 	(a)	any subsequent issuance or transfer of Equity Interests that results in any such Preferred Stock being held by a Person other than Parent, Issuer or a Restricted Subsidiary of Issuer or a Guarantor; and


  

	 	(b)	any sale or other transfer of any such Preferred Stock to a Person that is not either Parent, Issuer or a Restricted Subsidiary of Issuer, or a Guarantor, will be deemed, in each case, to constitute an issuance of such
Preferred Stock by such Restricted Subsidiary that was not permitted by this clause (7); 

  

	(8)	the incurrence by Issuer or any of its Restricted Subsidiaries of Hedging Obligations (other than for speculative purposes); 

  

	(9)	the guarantee by Issuer or any of the Subsidiary Guarantors of Indebtedness of Issuer or a Restricted Subsidiary of Issuer that was permitted to be incurred by another provision of this covenant; provided that if
the Indebtedness being guaranteed is subordinated to or pari passu with the notes, then the guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 


 

	(10)	 the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness in respect of workers’
compensation claims, self-insurance obligations, bankers’ acceptances, deposits, performance bonds, 



  
 A-16 









	 	
completion bonds, bid bonds, appeal bonds and surety bonds, indemnity bonds, specific performance or injunctive relief bonds or similar bonds or obligations in the ordinary course of business,
and any Guarantees or letters of credit functioning as or supporting any of the foregoing; 

  

	(11)	the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness arising from (a) the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against
insufficient funds, so long as such Indebtedness is covered within five Business Days of notice to Issuer or any of its Restricted Subsidiaries, (b) in respect of netting, overdraft protection and other arrangement arising under standard
business terms of any bank at which Issuer or any Restricted Subsidiary maintains an overdraft, cash pooling or other similar facility or arrangement or (c) in respect of the financing of insurance premiums in the ordinary course of business,
provided that the aggregate principal amount of Indebtedness incurred pursuant to clauses (11)(b) and (c) shall not, at any time outstanding, exceed the greater of (x) $250.0 million and (y) 5.0% of the Consolidated Cash
Flow of Issuer as of the time of such incurrence; 

  

	(12)	the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness in respect of letters of credit required to be issued in connection with any Permitted Joint Venture Investment; 


 

	(13)	the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness for relocation or clearing obligations relating to Issuer’s or any of its Restricted Subsidiary’s FCC Licenses in an aggregate
principal amount (or accreted value, as applicable), including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (13), at any time outstanding
not to exceed the greater of (x) $400.0 million and (y) 1.0% of Issuer’s Total Assets as of the time of such incurrence; 

  

	(14)	the incurrence by Issuer or any of its Restricted Subsidiaries of Contribution Indebtedness; 

  

	(15)	the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness (including Acquired Debt or Indebtedness) used to finance an acquisition of or a merger with another Person, provided that, Issuer or
the Person formed by or surviving any such consolidation or merger (if other than Issuer or a Restricted Subsidiary), on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had
occurred at the beginning of the applicable four-quarter period, would either (a) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Debt to Cash Flow Ratio test set forth in the first paragraph of this covenant or
(b) have a Debt to Cash Flow Ratio no greater than the Debt to Cash Flow Ratio of Issuer immediately prior to such transaction; 

  

	(16)	the incurrence by Issuer or any of its Restricted Subsidiaries of Indebtedness arising from agreements providing for indemnification, adjustment of purchase price or similar obligations, or Guarantees or letters of
credit, surety bonds or performance bonds securing any obligations of Issuer or any of its Restricted Subsidiaries pursuant to such agreements, in any case incurred in connection with the disposition of any business, assets or Restricted Subsidiary
(other than Guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or Restricted Subsidiary for the purpose of financing such acquisition), so long as the amount does not exceed the gross proceeds
actually received by Issuer or any Restricted Subsidiary thereof in connection with such disposition; 

  

	(17)	the incurrence by Issuer or any Restricted Subsidiary of Indebtedness constituting reimbursement obligations with respect to letters of credit issued in the ordinary course of business; provided that, upon the

made during such twelve-month period pursuant to clause (5) of the third paragraph under the covenant described above under the caption “—Restricted Payments,” less the amount of Restricted Payments that have been made during
such twelve-month period pursuant to such clause; 

  

	(22)	the incurrence by Issuer or any Restricted Subsidiary of Indebtedness consisting of take-or-pay obligations contained in supply agreements entered into in the ordinary course of business; 


 

	(23)	to the extent that deposits with, or payments owed to, the FCC in connection with the auction or licensing of Governmental Authorizations are deemed to be Indebtedness, the incurrence by Issuer or any Restricted

	(24)	Indebtedness incurred in connection with the Towers Transaction; and 

  

	(25)	the incurrence by Restricted Subsidiaries that are not Guarantors of Indebtedness; provided, however, that the aggregate principal amount (or accreted value, as applicable) of all Indebtedness incurred
under this clause (25), when aggregated with the principal amount (or accreted value) of all other Indebtedness then outstanding and incurred pursuant to this clause (25), including all Permitted Refinancing Indebtedness incurred to renew, refund,
refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (25), does not exceed the greater of (x) $250.0 million and (y) 5.0% of the Consolidated Cash Flow of Issuer and its Subsidiaries for the most
recently ended four full fiscal quarters for which financial statements are available. 

 For purposes of (x) determining
compliance with this “Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock” covenant, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt
described in clauses (1) through (25) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, Issuer will be permitted to classify all or a portion of such item of Indebtedness on the date of its incurrence,
or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant; provided, however that Indebtedness outstanding under the Term Loan Credit Agreement on the Issue Date shall be deemed
to have been incurred under clause (1) above and (y) determining the amount of Indebtedness that may be incurred pursuant to clause (1)(a)(y) of the definition of Permitted Debt, Issuer may elect, pursuant to an officers’
certificate delivered to the trustee, to treat all or any portion of the commitment under any Indebtedness (and any refinancing with respect thereto) as being incurred at such time, in which case any subsequent incurrence of Indebtedness under such
commitment or refinancing, as the case may be, shall not be deemed, for purposes of this calculation, to be an incurrence at such subsequent time. The accrual of interest, the accretion or amortization of original issue discount, the payment of
interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of Preferred Stock as Indebtedness due to a change in accounting principles or the application thereof, and the payment of dividends on
Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant. Notwithstanding any other
provision of this covenant, the maximum amount of Indebtedness that Issuer or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values,
and in no event shall the reclassification of any lease or other liability as indebtedness due to a change in accounting principles after the Closing Date be deemed to be an incurrence of Indebtedness. In determining the amount of Indebtedness
outstanding under one of the clauses above, the outstanding principal amount of any particular Indebtedness of any Person shall be counted only once and any obligation of such Person or any other Person


  
 A-18 








 
arising under any guarantee, Lien, letter of credit or similar instrument supporting such Indebtedness shall be disregarded so long as it is permitted to be incurred by the Person or Persons
incurring such obligation. 
 The amount of any Indebtedness outstanding as of any date will be: 

 

	 	(1)	the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount; 

  

	 	(2)	in the case of Hedging Obligations, the termination value of the agreement or arrangement giving rise to such obligations that would be payable by such Person at such time; 


 

	 	(3)	the principal amount of the Indebtedness, in the case of any other Indebtedness; and 

  

	 	(4)	in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of: 

  

	 	(a)	the Fair Market Value of such assets at the date of determination; and 

  

	 	(b)	the amount of the Indebtedness of the other Person. 

 Liens 

Issuer will not, and will not permit any Guarantor to, directly or indirectly, create, incur or assume any Lien securing Indebtedness upon any
asset now owned or hereafter acquired, except Permitted Liens, unless the notes are equally and ratably secured (except that Liens securing Indebtedness that is contractually subordinated to the notes shall be expressly subordinate to any Lien
securing the notes to at least the same extent that such Indebtedness is subordinate to the notes). 
 For purposes of determining
compliance with the covenant, (x) a Lien need not be incurred solely by reference to one category of Permitted Liens but may be incurred under any combination of such categories (including in part under one such category and in part under any
other such category) and (y) in the event that a Lien (or any portion thereof) meets the criteria of one or more of such categories of Permitted Liens, Issuer shall, in its sole discretion, divide, classify or may subsequently reclassify at any
time such Lien (or any portion thereof) in any manner that complies with this covenant and the definition of “Permitted Liens.” 

Dividend and Other Payment Restrictions Affecting Subsidiaries 

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
  

	(1)	pay dividends or make any other distributions on its Capital Stock to Issuer or any of its Restricted Subsidiaries, or pay any Indebtedness owed to Issuer or any of its Restricted Subsidiaries; 


 

	(2)	make loans or advances to Issuer or any of its Restricted Subsidiaries; or 

  

	(3)	sell, lease or transfer any of its properties or assets to Issuer or any of its Restricted Subsidiaries. 


However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of: 

 

	(1)	agreements or instruments governing (a) Existing Indebtedness and (b) Equity Interests and Credit Facilities as in effect on the Closing Date and, in each case, any amendments, restatements, modifications,
renewals, increases, supplements, refundings, replacements or refinancings of those agreements or instruments; provided that the amendments, restatements, modifications, renewals, increases, supplements, refundings, replacements or
refinancings are (in the good faith judgment of the Board of Directors of Issuer or a senior financial officer of Issuer, whose determination shall be conclusive) not materially more restrictive, taken as a whole, with respect to such dividend and
other payment restrictions than those contained in those agreements or instruments on the Closing Date; 


  
 A-19 









	(2)	agreements or instruments governing Credit Facilities not in effect on the Closing Date so long as either (a) the encumbrances and restrictions contained therein do not impair the ability of any Restricted
Subsidiary of Issuer to pay dividends or make any other distributions or payments directly or indirectly to Issuer in an amount sufficient to permit Issuer to pay the principal of, or interest and premium, if any, on the notes, or (b) the
encumbrances and restrictions contained therein are no more restrictive, taken as a whole, than those contained in the indenture; 

  

	(3)	Series Issue Date Existing Indebtedness, the notes issued on the Series Issue Date, and any additional notes of the same series, the Note Guarantees in respect thereof, and the base indenture, as supplemented by the
supplemental indenture; 

  

	(4)	applicable law, rule, regulation or order; 

  

	(5)	agreements or instruments with respect to a Person acquired by Issuer or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was
incurred in connection with or in contemplation of such acquisition) or as may be amended, restated, modified, renewed, extended, supplemented, refunded, replaced or refinanced from time to time (so long as the encumbrances and restrictions in any
such amendment, restatement, modification, renewal, extension, supplement, refunding, replacement or refinancing are, in the good faith judgment of Issuer’s Board of Directors or a senior financial officer of Issuer, whose determination shall
be conclusive, not materially more restrictive, taken as a whole, than those in effect on the date of the acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the
Person, or the property or assets of the Person, so acquired; provided that, in the case of agreements or instruments governing Indebtedness, such Indebtedness was permitted by the terms of the indenture to be incurred; 


 

	(6)	customary non-assignment provisions in contracts and licenses entered into in the ordinary course of business and customary contractual restrictions on transfers of all or substantially all assets of a Person;


  

	(7)	any instrument governing any secured Indebtedness or Capital Lease Obligation that imposes restrictions on the assets securing such Indebtedness or the subject of such lease of the nature described in clause (3) of
the preceding paragraph; 

  

	(8)	any agreement for the sale or other disposition of a Restricted Subsidiary that imposes restrictions of the nature described in clauses (1) and/or (3) of the preceding paragraph on the Restricted Subsidiary
pending the sale or other disposition; 

  

	(9)	Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those
contained in the agreements governing the Indebtedness being refinanced; 

  

	(10)	Liens permitted to be incurred under the provisions of the covenant described above under the caption “—Liens” that limit the right of the debtor to dispose of the assets subject to such Liens;


  

	(11)	provisions limiting the disposition or distribution of assets or property in partnership and joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar
agreements, which limitation is applicable only to the assets that are the subject of such agreements; 

  

	(12)	restrictions on cash or other deposits or net worth imposed by customers, suppliers or landlords or required by insurance, surety or bonding companies, in each case, under contracts entered into in the ordinary course
of business; 

  

	(13)	restrictions in other Indebtedness, Disqualified Stock or Preferred Stock incurred or issued in compliance with the covenant described under the caption “—Incurrence of Indebtedness and Issuance of
Disqualified Stock and Preferred Stock”; provided that such restrictions, taken as a whole, are, in the good faith judgment of Issuer’s Board of Directors or a senior financial officer of Issuer, whose determination shall be
conclusive, not materially more restrictive than those contained in the existing agreements referenced in clauses (1) and (3) above; 


  
 A-20 









	(14)	the issuance of Preferred Stock by a Restricted Subsidiary of Issuer or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such Preferred Stock is permitted pursuant
to the covenant described above under the caption “—Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock” and the terms of such Preferred Stock do not expressly restrict the ability of such Restricted
Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such Preferred Stock prior to paying any dividends or making any other distributions on such
other Capital Stock); 

  

	(15)	any agreement or instrument with respect to Indebtedness incurred, or Preferred Stock issued, by any Restricted Subsidiary, provided that the restrictions contained in the agreements or instruments governing such
Indebtedness or Preferred Stock (a) either (i) apply only in the event of a payment default or a default with respect to a financial covenant in such agreement or instrument or (ii) will not materially affect Issuer’s ability to
pay all principal, interest and premium, if any, on the notes, as determined in good faith by Issuer’s Board of Directors or a senior financial officer of Issuer, whose determination shall be conclusive; and (b) are not materially more
disadvantageous to the holders of the notes than is customary in comparable financings; 

  

	(16)	any agreement or instrument of Issuer, Parent, MetroPCS Wireless, Inc., or any of MetroPCS Wireless, Inc.’s Subsidiaries existing prior to, or entered into or assumed by Issuer or any of its Subsidiaries in
connection with the Merger, in each case, as such agreements or instruments may be amended, restated, modified, renewed or replaced from time to time; provided that the amendments, restatements, modifications, renewals, and replacements are
(in the good faith judgment of the Board of Directors of Issuer or a senior financial officer of Issuer, whose determination shall be conclusive) not materially more restrictive, taken as a whole, with respect to such encumbrances and restrictions
than those agreements or instruments as in effect as of the Closing Date; and 

  

	(17)	restrictions arising from the Towers Transaction. 

 Merger, Consolidation or Sale of
Assets 
 Issuer will not: (1) consolidate or merge with or into another Person (whether or not Issuer is the surviving
corporation); or (2) directly or indirectly sell, assign, lease, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of Issuer and its Restricted Subsidiaries taken as a whole, in one or more related
transactions, to another Person, unless: 
  

	(1)	either: (a) Issuer is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than Issuer) or to which such sale, assignment, lease, transfer, conveyance
or other disposition has been made is a corporation, limited liability company or partnership organized or existing under the laws of the United States, any state of the United States or the District of Columbia; 


 

	(2)	the Person formed by or surviving any such consolidation or merger (if other than Issuer) or the Person to which such sale, assignment, lease, transfer, conveyance or other disposition has been made expressly assumes,
by a supplemental indenture, executed and delivered to the trustee, the payment of the principal of and any premium and interest on the notes and the performance or observance of every covenant of the indenture on the part of Issuer to be performed
or observed; 

  

	(3)	immediately after such transaction, no Default or Event of Default exists; and 

  

	(4)	Issuer or the Person formed by or surviving any such consolidation or merger (if other than Issuer), or to which such sale, assignment, lease, transfer, conveyance or other disposition has been made would, on the date
of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, either (a) be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Debt to Cash Flow Ratio test set forth in the first paragraph of the covenant described above under the caption “—Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock” or
(b) have a Debt to Cash Flow Ratio no greater than the Debt to Cash Flow Ratio of Issuer immediately prior to such transaction. 


  
 A-21 








 Upon any consolidation or merger, or any sale, transfer, assignment, lease, conveyance or other
disposition of all or substantially all of the properties or assets of Issuer and its Restricted Subsidiaries, taken as a whole, in a transaction that is subject to, and that complies with the provisions of, this “Merger, Consolidation or Sale
of Assets” covenant, the successor Person formed by such consolidation or into or with which Issuer is merged or to which such sale, transfer, assignment, lease, conveyance or other disposition is made, shall succeed to, and be substituted for
Issuer (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, the provisions of the indenture referring to Issuer shall refer instead to the successor Person and not to
Issuer), and may exercise every right and power of Issuer under the indenture with the same effect as if such successor Person had been named as Issuer therein. When the successor Person assumes all of Issuer’s obligations under the indenture,
Issuer shall be discharged from those obligations. 
 This “Merger, Consolidation or Sale of Assets” covenant will not apply to
(and the following shall be permitted notwithstanding such covenant): 
  

	(1)	a merger of Issuer with a direct or indirect Subsidiary of Parent solely for the purpose of reincorporating Issuer in another jurisdiction in the United States so long as the amount of Indebtedness of Issuer and its
Restricted Subsidiaries is not increased thereby; 

  

	(2)	any consolidation or merger, or any sale, assignment, transfer, conveyance, lease or other disposition of assets between or among Issuer and its Restricted Subsidiaries; or 


 

	(3)	the Transactions, including the Merger. 

 Transactions with Affiliates 

Issuer will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose
of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of Issuer
(each, an “Affiliate Transaction”), in any one or series of related transactions involving aggregate payments or consideration in excess of $50.0 million, unless: 

 

	(1)	the Affiliate Transaction is on terms that, taken as a whole, are no less favorable to Issuer or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by Issuer or such
Restricted Subsidiary with an unrelated Person; and 

  

	(2)	Issuer delivers to the trustee: 

  

	 	(a)	with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $100.0 million, an officers’ certificate certifying that such Affiliate
Transaction complies with this covenant; and 

  

	 	(b)	with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $250.0 million, a resolution of the Board of Directors of Issuer set forth in an
officers’ certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of Issuer.


 The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions
of the prior paragraph: 
  

	(1)	any employment agreement, employee benefit plan, agreement or plan relating to employee, officer or director compensation or severance, officer or director indemnification agreement or any similar arrangement entered
into by Issuer, any of its Restricted Subsidiaries or a direct or indirect parent of Issuer existing on the Closing Date, or entered into thereafter in the ordinary course of business, and any indemnities or other transactions permitted or required
by bylaw, statutory provisions or any of the foregoing agreements, plans or arrangements and payments pursuant thereto; 


  
 A-22 









	(2)	transactions between or among Parent, Issuer and/or its Restricted Subsidiaries; 

  

	(3)	transactions with a Person (other than an Unrestricted Subsidiary of Issuer) that is an Affiliate of Issuer solely because Issuer owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls,
such Person; 

  

	(4)	any issuance of Equity Interests (other than Disqualified Stock) of Issuer to, or receipt of any capital contribution from, any Affiliate of Issuer; 


 

	(5)	transactions in connection with any Permitted Joint Venture Investment; 

  

	(6)	any Permitted Investments or Restricted Payments that do not violate the provisions of the indenture described above under the caption “—Restricted Payments”; 


 

	(7)	(x) any contracts, agreements or understandings existing as of the Issue Date and disclosed in the notes to the consolidated financial statements of MetroPCS Wireless, Inc. for the year ended December 31, 2012,
(y) any agreement listed on Schedule 3.2(r)—Related-Party Agreements—to the “T-Mobile Disclosure Letter” to the Business Combination Agreement, and (z) any agreement listed under the section entitled “Transactions
with Related Persons and Approval” in the proxy statement of Parent filed with the SEC under cover of Schedule 14A on April 16, 2012 and, in each case, any amendments to, replacements of, or orders pursuant to such contracts, agreements or
understandings so long as any such amendments, replacements, or orders, taken as a whole, are not (in the good faith judgment of Issuer’s Board of Directors or a senior financial officer of Issuer, whose determination shall be conclusive) more
disadvantageous to Issuer or to the holders of the notes in any material respect than the original contracts, agreements or understandings as in effect on the Closing Date; 


 

	(8)	transactions with customers, clients, suppliers, purchasers, sellers of goods or services, or licensees of intellectual property, in each case in the ordinary course of business and otherwise in compliance with the
terms of the indenture, provided that in the good faith determination of Issuer’s Board of Directors or a senior financial officer of Issuer, which determination shall be conclusive, such transactions are on terms, taken as a whole, not
materially less favorable to Issuer or the applicable Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s length basis from a Person that is not an Affiliate of
Issuer; 

  

	(9)	issuances, exchanges, purchases or repurchases of notes or other Indebtedness of Issuer or its Restricted Subsidiaries or solicitations of amendments, waivers or consents in respect of notes or such other Indebtedness,
if such issuance, exchange, purchase, repurchase or solicitation is approved by a majority of the disinterested members of the Board of Directors of Issuer; 

  

	(10)	reasonable payments made for any financial advisory, financing, underwriting, placement or syndication services approved by Issuer’s Board of Directors or a senior financial officer of Issuer in good faith;


  

	(11)	amendments, extensions, replacements and other modifications of transactions with Affiliates otherwise permitted by the indenture, provided that in the good faith determination of Issuer’s Board of Directors
or a senior financial officer of Issuer, which determination shall be conclusive, such amendments, extensions, replacements or other modifications, taken as a whole, are no less favorable in any material respect to Issuer or the applicable
Restricted Subsidiary than the transaction or transactions being amended, extended, replaced or modified; and 

  

	(12)	 (i) the Business Combination Agreement and any Ancillary Agreements, as defined in the Business Combination
Agreement, in each case, as the same may be amended, modified, supplemented or replaced from time to time on terms that, taken as a whole, in the good faith determination of Issuer’s Board of Directors or a senior financial officer of Issuer,
which determination shall be conclusive, are not materially less favorable to Issuer or the applicable Restricted Subsidiary than those of the agreement being amended, modified, supplemented or replaced, (ii) transactions or agreements relating
to the DT Notes and the TMUS Working Capital Facility, each as may be amended, modified, or supplemented from time to time, and any indebtedness incurred in connection with the refinancing of the foregoing, on terms that, taken as a whole,




  
 A-23 









	 	
in the good faith determination of Issuer’s Board of Directors or a senior financial officer of Issuer, which determination shall be conclusive, are not materially less favorable to Issuer
than those of the DT Notes or TMUS Working Capital Facility, as applicable, and (iii) transactions between Issuer and its Restricted Subsidiaries, on the one hand, and any Designated Tower Entities that have been designated as Unrestricted
Subsidiaries, on the other hand, in connection with the Towers Transaction. 

 Additional Note Guarantees 

If (a) Issuer or any of Issuer’s Domestic Restricted Subsidiaries acquires or creates another Domestic Restricted Subsidiary (and
such Subsidiary is a Wholly-Owned Subsidiary and is neither a Designated Tower Entity, the Reinsurance Entity nor an Immaterial Subsidiary) after the Series Issue Date or (b) any Restricted Subsidiary of Issuer guarantees any Specified Issuer
Indebtedness of Issuer after the Series Issue Date or (c) Parent or any Subsidiary of Parent acquires or creates a Subsidiary that directly or indirectly owns Equity Interests of Issuer, then Issuer or Parent, as applicable, will cause that
newly acquired or created Domestic Restricted Subsidiary, Restricted Subsidiary or Subsidiary of Parent to become a Guarantor of the notes and execute a supplemental indenture and, if requested by the trustee, deliver an opinion of counsel
reasonably satisfactory to the trustee within 10 Business Days after the date on which it was acquired or created or guarantees such Specified Issuer Indebtedness, as applicable, or reasonably promptly thereafter. 

Designation of Restricted and Unrestricted Subsidiaries 

The Board of Directors of Issuer may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a
Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, (i) the aggregate Fair Market Value of all outstanding Investments owned by Issuer and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted
Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the covenant described above under the caption “—Restricted Payments” or under one
or more clauses of the definition of Permitted Investments, as determined by Issuer in its discretion, and (ii) any Guarantee by Issuer or any Restricted Subsidiary thereof of any Indebtedness of the Restricted Subsidiary being so designated
will be deemed to be an incurrence of Indebtedness by Issuer or such Restricted Subsidiary (or both, if applicable) at the time of such designation. That designation will only be permitted if the Investment and/or incurrence of Indebtedness would be
permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of Issuer may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation
would not cause a Default. 
 Any designation of a Subsidiary of Issuer as an Unrestricted Subsidiary will be evidenced to the trustee by
filing with the trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an officers’ certificate certifying that such designation complied with the preceding conditions and was permitted by the
covenant described above under the caption “—Restricted Payments.” The Board of Directors of Issuer may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of Issuer; provided that such designation
will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of Issuer of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under the
covenant described under the caption “—Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock,” calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter
reference period; and (2) no Default would be in existence following such designation, and as a result of, such designation. 

Notwithstanding the foregoing, Issuer may at any time and from time to time designate any Designated Entity, by written notice to the trustee,
as an Unrestricted Subsidiary, and any such Subsidiary shall upon such notice immediately be designated and deemed an Unrestricted Subsidiary, without any further action by Issuer (and, for the avoidance of doubt, shall not require delivery of a
resolution of the Board of Directors or of an officers’ certificate) (each, a “Specified Unrestricted Subsidiary Designation”). The aggregate Fair Market Value 

  
 A-24 








 
of all outstanding Investments owned by Issuer and its Restricted Subsidiaries in such Designated Entities so designated as Unrestricted Subsidiaries will, as calculated and to the extent
permitted by clause (18) of the definition of Permitted Investments, be deemed to be an Investment made as of the time of such Specified Unrestricted Subsidiary Designation under such clause (18), and not reduce the amount available for
Restricted Payments under the covenant described above under the caption “—Restricted Payments.” 
 Reports

 Whether or not required by the rules and regulations of the SEC, so long as any notes are outstanding, Parent will file a copy of
each of the reports referred to in clauses (1) and (2) below with the SEC for public availability within the time periods (including all applicable extension periods) specified in the SEC rules and regulations applicable to such reports
(unless the SEC will not accept such a filing): 
  

	(1)	all quarterly and annual financial reports that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if Parent were required to file such reports, including a “Management’s
Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by its certified independent accountants; and 


 

	(2)	all current reports that would be required to be filed with the SEC on Form 8-K if Parent or Issuer were required to file such reports; 


provided that the availability of the foregoing reports on the SEC’s EDGAR service (or successor thereto) shall be deemed to satisfy Issuer’s
delivery obligations to the trustee and any holder of notes. 
 All such reports will be prepared in all material respects in accordance
with all of the rules and regulations applicable to such reports; provided that, if neither Parent nor Issuer is required under the rules and regulations of the SEC to file such reports with the SEC for public availability, such reports need
not be prepared in accordance with all of the rules and regulations applicable to such reports and shall only be required to include the information or disclosure that would be required by such form to the extent that, and in the same general style
of presentation as, the same or substantially similar information or disclosure is also included in the offering memorandum dated March 8, 2013 relating to the $1.75B Notes. Each annual report on Form 10-K will include a report on Parent’s
consolidated financial statements by Parent’s certified independent accountants. Issuer will at all times comply with TIA §314(a). 

If the SEC will not accept Parent’s or Issuer’s filings for any reason, Parent or Issuer will post the reports referred to in the
preceding paragraphs on its website, on intralinks.com or another website within the time periods that would apply if Parent were required to file those reports with the SEC (including all applicable extension periods). If (i) Issuer has
designated any of its Subsidiaries as Unrestricted Subsidiaries or (ii) the combined operations of Parent and its Subsidiaries, excluding the operations of Issuer and its Restricted Subsidiaries and excluding cash and Cash Equivalents, would,
if held by a single Unrestricted Subsidiary of Issuer, constitute a Significant Subsidiary of Issuer, then the quarterly and annual financial information required by the preceding paragraphs will include a reasonably detailed presentation, either on
the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of (A) in the case of (i) above, the financial condition and results of
operations of Parent, Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of Issuer and (B) in the case of (ii) above, the financial condition and results
of operations of Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of Parent and its other Subsidiaries; provided, however, that the requirements of this paragraph shall not apply if
Parent or Issuer files with the SEC the reports referred to in clauses (1) and (2) of the first paragraph of this covenant, and any such report contains the information required in this paragraph. 

For so long as any notes remain outstanding, if at any time they are not required to file with the SEC the reports required by the preceding
paragraphs, Issuer and the Guarantors will furnish to the holders of notes and to 

  
 A-25 








 
securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act of 1933, as amended (the
“Securities Act”). 
 Events of Default and Remedies 

Each of the following is an “Event of Default” in respect of the notes of a series: 

 

	(1)	default for 30 days in the payment when due of interest on the notes of such series; 

  

	(2)	default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the notes of such series; 


 

	(3)	failure by Issuer for 120 days after notice to Issuer by the trustee or the holders of at least 25% in aggregate principal amount of the notes of such series then outstanding voting as a single class to comply with the
provisions described under the caption “—Reports”; 

  

	(4)	failure by Issuer or any of its Restricted Subsidiaries for 30 days after notice to Issuer by the trustee or the holders of at least 25% in aggregate principal amount of the notes of such series then outstanding voting
as a single class to comply with the provisions described under the captions “—Repurchase at the Option of Holders—Change of Control Triggering Event” or “—Repurchase at the Option of Holders—Asset Sales” (in
each case other than a failure to purchase notes that will constitute an Event of Default under clause (2) above), or “—Certain Covenants—Merger, Consolidation or Sale of Assets”; 


 

	(5)	failure by Issuer or any of its Restricted Subsidiaries for 90 days after notice to Issuer by the trustee or the holders of at least 25% in aggregate principal amount of the notes of such series then outstanding voting
as a single class to comply with any of the other agreements in the indenture; 

  

	(6)	default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by Issuer or any of its Restricted Subsidiaries that
is a Significant Subsidiary (or any Restricted Subsidiaries that together would constitute a Significant Subsidiary) (or the payment of which is guaranteed by Issuer or any of its Restricted Subsidiaries that would constitute a Significant
Subsidiary), whether such Indebtedness or Guarantee now exists, or is created after the Series Issue Date with respect to such series of notes, if that default: 

  

	 	(a)	is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment
Default”); or 

  

	 	(b)	results in the acceleration of such Indebtedness prior to its express maturity; 

 and, in each
case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates an amount equal to
$100.0 million or more, in each case for so long as such failure or acceleration is continuing; 
  

	(7)	failure by Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary (or any Restricted Subsidiaries that together would constitute a Significant Subsidiary) to pay or discharge final judgments
entered by a court or courts of competent jurisdiction aggregating in excess of $100.0 million (to the extent not covered by insurance), which judgments are not paid, discharged or stayed for a period of 60 consecutive days following entry of such
final judgment or decree during which a stay of enforcement of such final judgment or decree, by reason of pending appeal or otherwise, is not in effect; 

  

	(8)	Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary, or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary, pursuant to or within the
meaning of Bankruptcy Law: 

  

	 	(a)	commences a voluntary case, 

  

	 	(b)	consents to the entry of an order for relief against it in an involuntary case, 


  
 A-26 









	 	(c)	consents to the appointment of a custodian of it or for all or substantially all of its property, 

  

	 	(d)	makes a general assignment for the benefit of its creditors, or 

  

	 	(e)	generally is not paying its debts as they become due; 

  

	(9)	a court of competent jurisdiction enters a final order or decree under any Bankruptcy Law that: 

  

	 	(a)	is for relief against Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary in an
involuntary case; 

  

	 	(b)	appoints a custodian of Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary or
for all or substantially all of the property of Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary; or


  

	 	(c)	orders the liquidation of Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary;


  

	 	(d)	and the final order or decree remains unstayed and in effect for 60 consecutive days; and 

  

	(10)	except as permitted by the indenture, any Note Guarantee with respect to the notes of such series is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and
effect, or any Guarantor, or any Person acting on behalf of any such Guarantor, denies or disaffirms its obligations under its Note Guarantee. 


In the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to Issuer, any Restricted Subsidiary
of Issuer that is a Significant Subsidiary or any group of Restricted Subsidiaries of Issuer that, taken together, would constitute a Significant Subsidiary, all outstanding notes of such series will become due and payable immediately without
further action or notice. However, the effect of such provisions may be limited by applicable laws. If any other Event of Default occurs and is continuing with respect to the any series of notes, the trustee or the holders, with a copy to the
trustee, of at least 25% in aggregate principal amount of the then outstanding notes of such series may declare all the notes of such series to be due and payable immediately. 

Subject to certain limitations, the holders of a majority in aggregate principal amount of the then outstanding notes of such series may
direct the trustee in its exercise of any trust or power. The trustee may withhold from holders of the notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or
Event of Default in the payment of interest or premium, if any, on, or the principal of, the notes of such series. 
 Subject to the
provisions of the indenture relating to the duties of the trustee, the trustee will be under no obligation to exercise any of the rights or powers under the indenture at the request or direction of any holders of notes unless such holders have
offered to the trustee indemnity or security satisfactory to it against any loss, liability or expense. 
 Except to enforce the right to
receive payment of principal, premium, if any, or interest when due, no holder of a note may pursue any remedy with respect to the indenture or the notes unless: 
  

	(1)	such holder has previously given to the trustee written notice that an Event of Default is continuing; 

  

	(2)	holders of at least 25% in aggregate principal amount of the then outstanding notes of the applicable series have made a written request to the trustee to institute proceedings in respect of such Event of Default in its
own name as trustee; 


  
 A-27 









	(3)	such holder or holders have offered the trustee security or indemnity satisfactory to it against any loss, liability or expense to be incurred in compliance with such request; 


 

	(4)	the trustee has not complied with such request within 90 days after receipt of the request and the offer of security or indemnity; and 


 

	(5)	during such 90-day period, holders of a majority in aggregate principal amount of the then outstanding notes of the applicable series have not given the trustee a direction inconsistent with such request.


 The holders of a majority in aggregate principal amount of the then outstanding notes of a series by written notice to the
trustee may, on behalf of the holders of all of the notes of such series, rescind an acceleration or waive any existing Default or Event of Default in respect of such series and its consequences under the indenture except a continuing Default or
Event of Default in the payment of interest or premium, if any, on, or the principal of, the notes of such series. 
 In the case of any
Event of Default occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of Issuer with the intention of avoiding payment of the premium that Issuer would have had to pay if Issuer then had elected to redeem the
notes pursuant to the optional redemption provisions of the indenture, an equivalent premium will also become and be immediately due and payable to the extent permitted by law upon the acceleration of the notes of such series. 

Issuer is required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any Default
or Event of Default, Issuer is required to deliver to the trustee a statement specifying such Default or Event of Default. 
 No Personal Liability of
Directors, Officers, Employees and Stockholders 
 No past, present or future director, officer, member, manager, partner, employee,
incorporator or stockholder of Issuer or any Guarantor, as such, will have any liability for any obligations of Issuer or the Guarantors under the notes, the indenture, the Note Guarantees, or for any claim based on, in respect of, or by reason of,
such obligations or their creation. Each holder of notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities
under the federal securities laws. 
 Legal Defeasance and Covenant Defeasance 

Issuer may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an officers’ certificate, elect to
have all of its obligations discharged with respect to the outstanding notes of any series and all obligations of the Guarantors discharged with respect to their Note Guarantees with respect to such series (“Legal Defeasance”)
except for: 
  

	(1)	the rights of holders of outstanding notes of such series to receive payments in respect of the principal of, or interest or premium, if any, on, the notes when such payments are due from the trust referred to below;


  

	(2)	Issuer’s obligations with respect to the notes of such series concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for
payment of money for security payments held in trust; 

  

	(3)	the rights, powers, trusts, duties, indemnities and immunities of the trustee, and Issuer’s and the Guarantors’ obligations in connection therewith; and 


 

	(4)	the Legal Defeasance and Covenant Defeasance provisions of the indenture. 

 In addition, Issuer
may, at its option and at any time with respect to any series of notes, elect to have the obligations of Issuer and the Guarantors released with respect to the provisions of the indenture described above


  
 A-28 








 
under “—Repurchase at the Option of Holders” and under the caption “—Certain Covenants” (other than the covenant described under the caption “—Certain
Covenants—Merger, Consolidation or Sale of Assets,” except to the extent described below) and the limitation imposed by clause (4) under the caption “—Certain Covenants—Merger, Consolidation or Sale of Assets”
(such release and termination being referred to as “Covenant Defeasance”), and thereafter any omission to comply with such obligations or provisions will not constitute a Default or Event of Default with respect to such notes. In the event
Covenant Defeasance occurs with respect to any series of notes in accordance with the indenture, the Events of Default described under clauses (3) through (9) under the caption “—Events of Default and Remedies” (in the case
of clauses (8) and (9), only with respect to Issuer’s Subsidiaries), in each case, will no longer constitute an Event of Default. 

In order to exercise either Legal Defeasance or Covenant Defeasance with respect to any series of notes: 

 

	(1)	Issuer must irrevocably deposit with the trustee or its designee, in trust, for the benefit of the holders of such series of notes, cash in U.S. dollars, non- callable Government Securities, or a combination of cash in
U.S. dollars and non-callable Government Securities, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, and premium, if
any, and interest on, the outstanding notes of such series on the stated date for payment thereof or on the applicable redemption date, as the case may be, and Issuer must specify whether such notes are being defeased to such stated date for payment

solely for the benefit of the holders of such series of notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in such amounts as will be sufficient, without
consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the notes of such series not delivered to the trustee for cancellation for principal of, and premium, if any, and accrued interest to the date of maturity
or redemption; provided that upon any redemption that requires 



  
 A-31 









	 	
the payment of the Applicable Premium, the amount deposited shall be sufficient for purposes of the indenture to the extent that an amount is deposited with the trustee equal to the Applicable
Premium calculated as of the date of the notice of redemption, with any deficit as of the date of the redemption only required to be deposited with the trustee on or prior to the date of the redemption; 


 

	(2)	Issuer or any Guarantor has paid or caused to be paid all sums payable by it under the indenture with respect to the notes of such series; and

precedent set forth in clauses (1) through (3) above have been satisfied, and (b) an opinion of counsel(which opinion of counsel may be subject to customary assumptions, qualifications and exclusions), stating that all conditions

 Governing Law 

The indenture, the notes and the Note Guarantees will be governed by the laws of the State of New York. 

Concerning the Trustee 
 We maintain
ordinary banking relationships with Deutsche Bank Trust Company Americas and its affiliates. 
 If the trustee becomes a creditor of Issuer
or any Guarantor, the indenture limits the right of the trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage
in other transactions; however, if it acquires any conflicting interest when a Default is continuing it must eliminate such conflict within 90 days of the date such conflict arises, apply to the SEC for permission to continue as trustee (if the
indenture has been qualified under the Trust Indenture Act) or resign. 
 The holders of a majority in aggregate principal amount of the
then outstanding notes of the applicable series will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions. The indenture provides that in
case an Event of Default occurs and is continuing, the trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. 

Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request
of any holder of notes of the applicable series, unless such holder has offered to the trustee security and indemnity satisfactory to it against any loss, liability or expense.

quarter reference period.
