DESCRIPTION OF NOTES

You can find the definitions of certain terms used in this description of the 5.250% senior notes due 2018, the 6.250% senior notes due 2021 and the 6.625% senior notes due 2023 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 not to any of its Subsidiaries.

Issuer will issue the 2021 exchange notes and the 2023 exchange notes as two series of debt securities under that certain base indenture, dated March 19, 2013 (the “ March 2013 base indenture ”), among itself, Parent, the Subsidiary Guarantors and Deutsche Bank Trust Company Americas, as trustee (the “ trustee ”) as supplemented with respect to each of such series of the exchange notes by a separate supplemental indenture, and Issuer will issue the 2018 exchange notes as a series of debt securities under that certain base indenture, dated April 28, 2013 (the “ April 2013 base indenture ” and with the March 2013 base indenture, the “ base indentures ,” or separately a “ base indenture ”), among itself, Parent, the Subsidiary Guarantors and the trustee, as supplemented with respect to such series of the exchange notes by a separate supplemental indenture (for each such series of notes the “ supplemental indenture ”). In this description of the exchange notes, the term “ indenture ” refers to the applicable base indenture as supplemented separately by the applicable supplemental indenture or applicable supplemental indentures, for each series of notes. The terms of the exchange notes of each series include those stated in the applicable indenture and those made part of the applicable 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, its direct parent company. 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 indentures applicable to both the exchange notes and the original notes. As such, when we refer to each of the “ 2018 notes, ” the “ 2021 notes” and the “2023 notes ” we are describing the material provisions of each such series of both the original notes and the exchange notes. The following description does not restate the indentures in their entirety. We urge you to read each indenture applicable to the series of notes you hold in their entirety because such indentures, and not this description of the notes, defines your rights as a holder of the notes. For more information on how you can obtain a copy of the applicable base indenture and applicable supplemental indenture, see “Where You Can Find More Information.” Certain defined terms used in this description of the notes but not defined below under “—Certain Definitions” have the meanings assigned to them in the applicable 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 applicable indenture.

The Notes

The original notes of each series are and the exchange notes of such series will be:

However, the notes will be effectively subordinated to all existing and future secured Indebtedness of Issuer or any Guarantor to the extent of the assets securing such Indebtedness and structurally subordinated to all

liabilities and preferred stock of any of Issuer’s Subsidiaries that do not guarantee the notes to the extent of the assets of those Subsidiaries. See “Risk Factors—Risks Related to the Notes—The exchange notes and the guarantees will be unsecured and effectively subordinated to Issuer’s and the guarantors’ existing and future secured indebtedness and structurally subordinated to any future indebtedness and other liabilities of Issuer’s non-guarantor subsidiaries.”

As of September 30, 2013, assuming Issuer had completed the November 2013 Notes Offering, Issuer would have had approximately $22.6 billion of outstanding indebtedness on a pro forma basis, including $19.6 billion of outstanding indebtedness under Issuer’s senior notes (including the original notes), approximately $0.4 billion of which would have been secured (and including approximately $2.49 billion of long term financial obligation relating to the Towers Transaction). Issuer’s Subsidiaries that do not guarantee the original notes and will not guarantee the exchange notes had approximately $1 billion of total assets (excluding receivables due from Issuer and its guarantor Subsidiaries) and $2.3 billion in Indebtedness, other liabilities and preferred stock as of September 30, 2013.

The Note Guarantees

The original notes are, and the exchange 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 are joint and several obligations of the Guarantors. The obligations of each Guarantor under its Note Guarantee are 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 Guarantor’s guarantee relating to the original notes is and its guarantee of the exchange notes will be:

However, the Note Guarantees are effectively subordinated to all existing and future secured Indebtedness of the Guarantors to the extent of the assets securing such Indebtedness and structurally subordinated to all liabilities and preferred stock of any Subsidiaries of such Guarantors that do not guarantee the notes to the extent of the assets of those Subsidiaries. See “Risk Factors—Risks Related to the Notes—The exchange notes and the guarantees will be unsecured and effectively subordinated to Issuer’s and the guarantors’ existing and future secured indebtedness and structurally subordinated to any future 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 applicable to each series of original notes, all of Issuer’s Subsidiaries were “Restricted Subsidiaries.” However, under the circumstances described below under the caption “—Certain

Table of Contents

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 applicable 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; 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 applicable indenture and its Note Guarantee of the notes pursuant to a supplemental indenture; or

(b) such sale or other disposition complies with the “Asset Sale” provisions of the applicable 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 such 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 applicable 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 applicable 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 notes pursuant to the covenant described below under the caption “—Additional Note Guarantees”;

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

(5) upon the legal defeasance, covenant defeasance, or satisfaction and discharge of the applicable 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 notes pursuant to the covenant described below under the caption “—Additional Note Guarantees.”

See “—Repurchase at the Option of Holders—Asset Sales” below.

Principal, Maturity and Interest

Issuer has outstanding $19.2 billion in aggregate principal amount of senior notes, including the original notes to be exchanged for the exchange notes. Issuer may issue additional notes from time to time, and such additional notes may be issued either under one of the base indentures as supplemented by one or more other supplemental indentures. Any issuance of additional notes is subject to all of the covenants in the applicable indentures, including the covenant described below under the caption “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock.” The original notes and any additional notes subsequently issued, together with the exchange notes issued in accordance with the applicable registration rights agreement, will be treated as a single series for all purposes under the applicable indentures, 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 2018 notes will mature on September 1, 2018. The 2021 notes will mature on April 1, 2021. The 2023 notes will mature on April 1, 2023.

Interest on the 2018 notes will accrue at the rate of 5.250% per annum and will be payable semiannually in arrears on March 1 and September 1, commencing on March 1, 2014. Issuer will make each Issuer will make each interest payment to the holders of record of the 2018 notes on the immediately preceding February 15 and August 15.

Interest on the 2021 notes will accrue at the rate of 6.250% per annum, and interest on the 2023 notes will accrue at the rate of 6.625% per annum, and in either case will be payable semiannually in arrears on April 1 and October 1, commencing on October 1, 2013. Issuer will make each Issuer will make each interest payment to the holders of record of the 2021 notes and the 2023 notes on the immediately preceding March 15 and September 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 the 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 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 paying agent and registrar initially is the trustee. 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 definitive notes may transfer or exchange the notes in accordance with the provisions of the applicable indentures. 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.

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 the 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 pursuant to a Change of Control Offer on the terms set forth in the applicable 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 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 applicable indenture and described in such notice. 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 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 applicable indenture, or compliance with the Change of Control Triggering Event provisions of the applicable 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

52

Table of Contents

of the applicable 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.

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 applicable indenture are applicable. Except as described above with respect to a Change of Control Triggering Event, the applicable 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 the notes in the manner, at the times and otherwise in compliance with the requirements set forth in the applicable indenture that apply to a Change of Control Offer made by Issuer and purchases all of such series of notes 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 applicable 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 any series of the notes accept a Change of Control Offer and Issuer purchases all of the notes held by such holders, Issuer will have the right, upon not less than 10 nor more than 60 days’ notice (in the case of redemptions upon less than 30 days’ notice, subject to the ability of DTC to process such redemption on the date specified in such notice), given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of such series of the notes 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 on the notes 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).

Table of Contents

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

(2) at least 75% of the consideration received by Issuer or such Restricted Subsidiary in the Asset Sale and all other Asset Sales since (i) the Closing Date in the case of the 2018 notes, and (ii) September 21, 2010 in the case of the 2021 notes and the 2023 notes, 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; and

(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.

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; or

(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.

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 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.

54

Table of Contents

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 applicable 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 the 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 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 applicable 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 applicable indenture, or compliance with the Asset Sale provisions of the applicable 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 applicable 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 indentures governing the exchange notes offered hereby and our other existing senior notes, as well as our TMUS Working Capital Facility, include restrictive covenants that limit our operating flexibility.”

Selection and Notice

If less than all of a series of the notes are to be redeemed, the trustee will select notes such series for redemption on a pro rata basis unless otherwise required by law or applicable stock exchange or depositary requirements.

55

Table of Contents

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 notes of a series or a satisfaction and discharge of the applicable indenture. Except as otherwise set forth in the provisions described under the caption “—Repurchase at the Option of Holders—Change of Control Triggering Event,” notices of redemption may not be conditional.

If any exchange note is to be redeemed in part only, the notice of redemption that relates to that exchange note will state the portion of the principal amount of that exchange note that is to be redeemed. If in definitive form a new exchange note in principal amount equal to the unredeemed portion of the original exchange note will be issued in the name of the holder of notes upon cancellation of the original exchange 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:

(1) the notes of any 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 will cease to apply to such series of the notes and will not be later reinstated even if the ratings of such series of the notes should subsequently decline:

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

(2) “—Restricted Payments”;

(3) “—Incurrence of Indebtedness and Issuance of 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 will ever achieve an Investment Grade rating.

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

(2) 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 Preferred Stock”; and

(3) 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) and (15) of the next succeeding paragraph), is less than the sum, without duplication, of:

Incurrence of Indebtedness and Issuance of 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 ,

Table of Contents

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 6.0 to 1, 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.

(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) 150% 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, calculated on a pro forma basis in the manner described in the definition of “ Debt to Cash Flow Ratio ” 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 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 original notes to be issued on the date of the supplemental indenture and the notes to be issued in exchange therefor and, in each case, the related Note Guarantees;

(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:

cash of all Obligations then due with respect to the notes, in the case of Issuer, or the related 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:

(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, 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 arrangements 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 $250.0 million;

Issuer will not incur, and will not permit any Subsidiary Guarantor to incur, any Indebtedness (including Permitted Debt, but excluding Indebtedness permitted by clause (6) above) that is contractually subordinated in

62

Table of Contents

right of payment to any other Indebtedness of Issuer or such Subsidiary Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the notes and the applicable Note Guarantee on substantially identical terms; provided , however , that no Indebtedness shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of Issuer or any Subsidiary Guarantor solely by virtue of such Indebtedness being unsecured or by virtue of such Indebtedness being secured on a first or junior Lien basis.

For purposes of (x) determining compliance with this “Incurrence of Indebtedness and Issuance of 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 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 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 of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist 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).

(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 applicable indenture;

(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;

(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 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; and

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; provided that if such Person is not a corporation, such Person immediately causes a Subsidiary that is a corporation organized or existing under the laws of the United States, any state of the United States or the District of Columbia to be added as a co-issuer of the notes under the applicable indenture;

(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 applicable 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 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.

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 applicable 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 applicable 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 applicable 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

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;

67

Table of Contents

(8) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of the applicable 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, 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, purchase, repurchase or solicitation is approved by a majority of the disinterested members of the Board of Directors of Issuer;

(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, 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.

Business Activities

Issuer will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such extent as would not be material to Issuer and its Restricted Subsidiaries taken as a whole.

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

68

Table of Contents

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 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 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.”

Payments for Consent

Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of any series of notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the applicable indenture with respect to the notes or the notes unless such consideration is offered to be paid and is paid to all holders of such series of notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment.

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 $3.5B 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 securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(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 such series of the notes then outstanding voting as a single class to comply with any of the other agreements in the applicable 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, 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:

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

71

Table of Contents

(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;

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

(10) except as permitted by the applicable indenture, any Note Guarantee with respect to such series of the notes 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 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 any series of the notes, the trustee or the holders, with a copy to the trustee, of at least 25% in aggregate principal amount of such then outstanding series of notes may declare all such series of the notes 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 a series may direct the trustee in its exercise of any trust or power in respect of such series. 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.

Subject to the provisions of the applicable 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 any series of notes may pursue any remedy with respect to the applicable 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 applicable series of notes then outstanding have made a written request to the trustee to institute proceedings in respect of such Event of Default in its own name as trustee;

(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 any series of the then outstanding notes have not given the trustee a direction inconsistent with such request.

The holders of a majority in aggregate principal amount of any series of the then outstanding notes by written notice to the trustee may, on behalf of the holders of all such series of the notes, rescind an acceleration

or waive any existing Default or Event of Default in respect of such series and its consequences under the applicable indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, such series of the notes.

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 applicable 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.

Issuer is required to deliver to the trustee annually a statement regarding compliance with the applicable 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 applicable 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 any series of the notes outstanding and all obligations of the Guarantors discharged with respect to their Note Guarantees (“ Legal Defeasance ”) except for:

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

(2) Issuer’s obligations with respect to such series of notes 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 applicable indenture.

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

Governing Law

The indentures, the notes and the Note Guarantees are 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 indentures limit 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 applicable indenture has been qualified under the Trust Indenture Act) or resign.

The holders of a majority in aggregate principal amount of the applicable series of notes then outstanding 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 applicable to each series of notes 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 applicable indenture at the request of any holder of the applicable series of the notes, unless such holder has offered to the trustee security and indemnity satisfactory to it against any loss, liability or expense.
