INDENTURE, dated as of March 31, 2023, among Level 3 Financing, Inc., a corporation duly organized and existing under the laws of the State of Delaware (the “Issuer”), having its principal office at 1025 Eldorado Blvd., Broomfield, Colorado 80021, Level 3 Parent, LLC, a limited liability company duly organized and existing under the laws of the State of Delaware (herein called “Level 3 Parent”), having its principal office at 1025 Eldorado Blvd., Broomfield, Colorado 80021, the other Guarantors party hereto and The Bank of New York Mellon Trust Company, N.A., a national banking association, as Trustee and as Note Collateral Agent.

RECITALS OF THE ISSUER

The Issuer has duly authorized the creation of an issue of 10.500% Senior Secured Notes Due 2030 (the “Securities”), of substantially the tenor and amount hereinafter set forth, and to provide therefor the Issuer, Level 3 Parent and the Guarantors party hereto have duly authorized the execution and delivery of this Indenture.

All things necessary have been done to make the Securities, when executed by the Issuer and authenticated and delivered hereunder and duly issued by the Issuer, the valid and legally binding obligations of the Issuer and to make this Indenture a valid and legally binding agreement of each of the Issuer, Level 3 Parent, the Guarantors party hereto, the Trustee and the Note Collateral Agent, in accordance with their and its terms.

On each settlement date of the Exchange Offers, Level 3 LLC will issue an intercompany demand note to Level 3 Parent in an amount equal to the aggregate principal amount of Securities that are issued by the Issuer in the Exchange Offers on such settlement date (each, an “Exchange Consideration Note”) in exchange for a reduction of an equivalent amount of the outstanding balance under the Parent Intercompany Note. Level 3 Parent will then contribute the Exchange Consideration Note to the Issuer and the Issuer will then deliver the Exchange Consideration Note to Level 3 LLC for extinguishment in exchange for an equivalent increase in the outstanding balance of the Loan Proceeds Note. The Issuer will then contribute the Lumen Notes that it acquires in the Exchange Offers on such settlement date to Level 3 LLC and, in return, Level 3 LLC will deliver such Lumen Notes to Level 3 Parent in exchange for a reduction of the amount of the outstanding balance under the Parent Intercompany Note equal to the principal amount of the Securities issued in exchange for such Lumen Notes. Level 3 Parent will then distribute such Lumen Notes to its parent company, which in turn will distribute such Lumen Notes to Lumen for retirement and cancellation.

The Issuer has pledged the Loan Proceeds Note and each of the Existing Proceeds Notes to secure its obligations under the Existing Issuer Credit Facility and the Existing Secured Notes and will pledge the Loan Proceeds Note and each of the Existing Proceeds Notes to secure its obligations under the Securities. Level 3 Parent has pledged the Parent Intercompany Note to secure its obligations under the Existing Issuer Credit Facility and the Existing Secured Notes and will pledge the Parent Intercompany Note to secure its obligations under the Securities.

Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include:

(2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(4) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with.

SECTION 103. Form of Documents Delivered to Trustee.

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an officer of the Issuer or any Guarantor may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Issuer or any Guarantor, respectively, stating that the information with respect to such factual matters is in the possession of the Issuer or any Guarantor, respectively, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated (with proper identification of each matter covered therein) and form one instrument.

SECTION 104. Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution

thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient.

(c) The principal amount and serial numbers of Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.

(d) If the Issuer shall solicit from the Holders of Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Issuer may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Issuer shall have no obligation to do so. Such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

(e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Issuer in reliance thereon, whether or not notation of such action is made upon such Security. However, any such Holder or future Holder may revoke the request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date such Act becomes effective.

SECTION 105. Notices, etc., to Trustee and the Issuer.

Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(1) the Trustee by any Holder or by the Issuer shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Administration, or

(2) the Note Collateral Agent by any Holder or by the Issuer shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Note Collateral Agent c/o the Trustee as described in clause (1) above, or

(3)

(4) the Issuer or any Guarantor by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, or electronically to the Issuer or such Guarantor addressed to it (in the case of a Guarantor, in care of the Issuer) at the address of the Issuer’s principal office specified in the first paragraph of this Indenture and to 1025 Eldorado Boulevard, Broomfield, CO 80021, Attention: Treasury department, or at any other address previously furnished in writing to the Trustee by the Issuer.

The Trustee agrees to accept and act upon instructions or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods, provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Issuer elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling. Except to the extent relating to matters arising out of the Trustee’s gross negligence or willful misconduct, the Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding that such instructions conflict or are inconsistent with a subsequent written instruction. The Issuer agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties.

SECTION 106. Notice to Holders; Waiver.

Where this Indenture provides for notice of any event to Holders by the Issuer or the Trustee, such notice shall be given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the address of such Holder as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Notices shall be effective only upon receipt. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

In case by reason of the suspension of or irregularities in regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice for every purpose hereunder.

SECTION 107. Effect of Headings and Table of Contents.

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 108. Successors and Assigns.

All covenants and agreements in this Indenture by the Issuer and Level 3 Parent shall bind its successors and assigns, whether so expressed or not.

SECTION 109. Separability Clause.

In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 110. Benefits of Indenture.

Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Security Registrar and their successors hereunder and the Holders any legal or equitable right, remedy or claim under this Indenture.

SECTION 111. Governing Law.

THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

SECTION 112. Trust Indenture Act.

For the avoidance of doubt, the Trust Indenture Act is not applicable to this Indenture.

SECTION 113. Legal Holidays.

In any case where any Interest Payment Date, Redemption Date, or Stated Maturity or Maturity of any Security shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Securities) payment of principal (or premium, if any) or interest need not be made on such date, but shall be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or Redemption Date or at the Stated Maturity or Maturity; provided that no interest shall accrue in respect of such payment for the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or Maturity to the next Business Day, as the case may be.

SECTION 114. No Personal Liability of Directors, Officers, Employees and Stockholders.

No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, shall have any liability for any obligations of the Issuer or any Guarantor under the Securities or this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation, solely by reason of its status as a director, officer, employee, incorporator or stockholder of the Issuer or a Guarantor. By accepting a Security, each Holder waives and releases all such liability (but only such liability). The waiver and release are part of the consideration for issuance of the Securities.

SECTION 115. Independence of Covenants.

All covenants and agreements in this Indenture shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or be otherwise within the limitations of, another covenant shall not avoid the occurrence of a Default if such action is taken or condition exists.

SECTION 116. Exhibits.

All exhibits attached hereto are by this reference made a part hereof with the same effect as if herein set forth in full.

SECTION 117. Counterparts.

This Indenture may be executed in any number of counterparts, each of which shall be an original; but such counterparts shall together constitute but one and the same instrument.

SECTION 118. Duplicate Originals.

SECTION 119. Waiver of Jury Trial.

EACH OF LEVEL 3 PARENT, THE ISSUER, EACH HOLDER BY ACCEPTANCE OF THE SECURITIES, THE TRUSTEE AND THE NOTE COLLATERAL AGENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE SECURITIES OR THE TRANSACTIONS CONTEMPLATED HEREBY.

SECTION 120. Force Majeure.

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, pandemics or epidemics, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

SECTION 121. FATCA.

In order to assist the Trustee with its compliance with Sections 1471 through 1474 of the Code and the rules and regulations thereunder (as in effect from time to time, collectively, the “Applicable Law”), the Issuer agrees (i) to provide to the Trustee reasonably available information collected and stored in the Issuer’s ordinary course of business regarding Holders of Securities (solely in their capacity as such) and which is necessary for the Trustee’s determination of whether it has tax related obligations under Applicable Law and (ii) that the Trustee shall be entitled to make any withholding or deduction from payments under this Indenture to the extent necessary to comply with Applicable Law. Nothing in the immediately preceding sentence shall be construed as obligating the Issuer to make any “gross up” payment or similar reimbursement in connection with a payment in respect of which amounts are so withheld or deducted.

SECTION 122. Submission to Jurisdiction.

The parties irrevocably submit to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, City of New York, over any suit, action or proceeding arising out of or relating to this Indenture. To the fullest extent permitted by applicable law, the parties irrevocably waive and agree not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

SECTION 123. Limited Condition Transactions.

For purposes of (i) determining compliance with any provision in this Indenture that requires the calculation of any financial ratio or test, (ii) determining compliance with the requirement regarding the absence of a Default or Event of Default (or any type of Default or Event of Default) or (iii) testing any ratio or cap measured as a percentage of Pro Forma Consolidated Cash Flow Available for Fixed Charges and any other availability of a “basket” or exception set forth in this Indenture, in each case, in connection with a Limited Condition Transaction, the date of determination, at the election of the Issuer (the Issuer’s election to exercise such option in connection with any Limited Condition Transaction, an “LCT Election”), shall be deemed to be at the time of (on the basis of the consolidated financial statements required to be delivered under Section 905 for the most recently ended four fiscal quarter period) either (x) the execution of the definitive acquisition agreements or other binding contracts with

respect to such transaction, or (y) the consummation of such transaction (such applicable date, the “LCT Test Date”), and if, after such ratios and other provisions are measured on a pro forma basis (determined in accordance with the applicable provisions of this Indenture) after giving effect to the Limited Condition Transaction and the other transactions to be entered into in connection therewith (including any Incurrence of Debt and the use of proceeds thereof) as if they had occurred at the beginning of the most recently completed four fiscal quarter period ending prior to the LCT Test Date, the Issuer could have taken such action on the relevant LCT Test Date in compliance with such ratios, absence of Default or Event of Default or “basket”, such ratio, absence of Default or Event of Default or “basket” shall be deemed to have been complied with.

For the avoidance of doubt, if the Issuer has made an LCT Election and (x) any of the ratios or “baskets” for which compliance was determined or tested as of the LCT Test Date are exceeded as a result of fluctuations in any such ratio or “basket” (including due to fluctuations of the target of any Limited Condition Transaction) at or prior to the consummation of the relevant Limited Condition Transaction, such “baskets” or ratios and other provisions shall not be deemed to have been exceeded as a result of such fluctuations solely for purposes of determining whether the Limited Condition Transaction is permitted hereunder and (y) in connection with any subsequent calculation of any ratio or “basket” availability on or following the relevant LCT Test Date and prior to the earlier of (i) the date on which such Limited Condition Transaction is consummated or (ii) the date that the definitive agreement for such Limited Condition Transaction is terminated or expires without consummation of such Limited Condition Transaction, any such ratio or “basket” availability shall be calculated on a pro forma basis (determined in accordance with the applicable provisions of this Indenture) assuming such Limited Condition Transaction and other transactions in connection therewith (including any Incurrence of Debt and the use of proceeds thereof (but without netting the cash proceeds thereof)) had been consummated.

SECTION 124. Electronic Signatures.

For the avoidance of doubt, for all purposes of this Indenture and any document to be signed or delivered in connection with or pursuant to this Indenture (except where a manual signature is expressly required by the terms of this Indenture), the words “execution,” “signed,” “signature,” “delivery,” and words of like import shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, as the case may be, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

ARTICLE TWO

SECURITY FORMS

SECTION 201. Form and Dating.

Provisions relating to the Securities are set forth in Appendix A, which is hereby incorporated in and expressly made a part of this Indenture. The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit 1 to Appendix A which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer is subject, if any, or usage, provided that any such notation, legend or endorsement is in a form reasonably acceptable to the Issuer. Each Security shall be dated the date of its authentication. The terms of the Securities set forth in Exhibit 1 to Appendix A are part of the terms of this Indenture.

The Definitive Securities shall be printed, lithographed or engraved on steel-engraved borders or may be produced in any other manner permitted by the rules of any securities exchange or system on which the Securities may be listed or eligible for trading, all as determined by the officers of the Issuer executing such Securities, as evidenced by their execution of such Securities.

ARTICLE THREE

THE SECURITIES

SECTION 301. Amount of Securities. Subject to Section 302, the Trustee shall authenticate Securities for original issue on the Issue Date in the aggregate principal amount of $915,108,000 (the “Original Securities”).

The Issuer shall be entitled, subject to its compliance with the covenants set forth in this Indenture, including Section 908, to issue Additional Securities under this Indenture which shall have identical terms as the Original Securities, other than with respect to the date of issuance and issue price (and such changes as are customary to permit escrow arrangements, if any, in connection with the issuance of such Additional Securities); provided that a separate CUSIP or ISIN shall be issued for any Additional Securities if the Additional Securities are not fungible for federal income tax purposes with the Original Securities. The Original Securities and any Additional Securities issued in exchange therefor shall be treated as a single class for all purposes under this Indenture.

With respect to the Additional Securities, the Issuer shall set forth in a Board Resolution and an Officers’ Certificate, a copy of each of which shall be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture;

(2) the issue price, the issue date and the CUSIP number of such Additional Securities; provided, however, that no Additional Securities may be issued after the expiration of the “period of thirteen days” described in Treasury Regulation Section 1.1275-1(f)(1)(iii) unless such issuance would be a “qualified reopening” within the meaning of Treasury Regulation Section 1.1275-2(k)(3); and

(3) whether such Additional Securities shall be Transfer Restricted Securities and issued in the form of Securities as set forth in Appendix A to this Indenture.

For each issuance of Additional Securities for cash proceeds, the Issuer shall use the net proceeds of each such issuance and additional funds as necessary to lend to Level 3 LLC an amount equal to the principal amount of the Additional Securities so issued, and the principal amount of the Loan Proceeds Note shall be increased by such amount. For each issuance of Additional Securities other than for cash proceeds, the Issuer shall consummate, and cause to be consummated, transactions similar to those set forth in the recitals hereof such that the principal amount of the Loan Proceeds Note is increased by the principal amount of the Additional Securities so issued.

SECTION 302. Execution and Authentication. Two officers shall sign the Securities for the Issuer by manual, electronic or facsimile signature.

If an officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

At any time and from time to time after the execution and delivery of this Indenture, the Issuer may deliver Securities executed by the Issuer to the Trustee for authentication, together with an Issuer Order for the authentication and delivery of such Securities, an Officers’ Certificate and an Opinion of Counsel and the Trustee in accordance with such written order of the Issuer shall authenticate and deliver such Securities.

A Security shall not be valid until an authorized signatory of the Trustee manually, electronically or by facsimile signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Security Registrar, Paying Agent or agent for service of notices and demands.

SECTION 303. Security Registrar and Paying Agent. The Issuer shall maintain an office or agency in the City of New York where Securities may be presented for registration of transfer or for exchange (the “Security Registrar”) and an office or agency in the City of New York where Securities may be presented for payment to the Paying Agent. The Security Registrar shall keep a register of the Securities and of their transfer and exchange (the register maintained in the office of the Security Registrar and in any other office or agency designated pursuant to Section 902 being herein sometimes referred to as the “Security Register”). The Issuer may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

The Issuer shall enter into an appropriate agency agreement with any Security Registrar, Paying Agent or co-registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee of the name and address of any such agent. If the Issuer fails to maintain a Security Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 607.

The Issuer initially appoints the Trustee as Security Registrar and Paying Agent in connection with the Securities.

SECTION 304. Paying Agent to Hold Money in Trust. Prior to each due date of the principal and interest on any Security, the Issuer shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Issuer in making any such payment. If the Issuer or a Wholly Owned Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 305. Holders Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Security Registrar, upon a written request by the Trustee, the Issuer shall furnish to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may reasonably request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

SECTION 306. Replacement Securities. If a mutilated Security is surrendered to the Security Registrar or if the Holder of a Security claims that such Security has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the UCC are met and the Holder satisfies any other reasonable requirements of the Trustee. Such Holder shall furnish an indemnity bond sufficient in the judgment of the Issuer and the Trustee to protect the Issuer, the Trustee, the Paying Agent, the Security Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Issuer and the Trustee may charge the Holder for their expenses in replacing a Security.

Every replacement Security is an additional obligation of the Issuer.

SECTION 307. Temporary Securities. Until Definitive Securities are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Issuer considers appropriate for temporary Securities. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Definitive Securities and deliver them in exchange for temporary Securities.

SECTION 308. Cancellation. The Issuer at any time may deliver Securities to the Trustee for cancellation. The Security Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of in accordance with its customary procedures (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation unless the Issuer directs the Trustee in writing to deliver canceled Securities to the Issuer. The Issuer may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancellation.

SECTION 309. Defaulted Interest. If the Issuer defaults in a payment of interest on the Securities, the Issuer shall pay the defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Issuer may pay the defaulted interest to the persons who are Holders on a subsequent special record date. The Issuer shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

SECTION 310. CUSIP Numbers. The Issuer in issuing the Securities may use “CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that neither the Issuer nor the Trustee shall have any responsibility for any defect in the “CUSIP” number that appears on any Security, check, advice of payment or redemption notice, and any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer will promptly notify the Trustee in writing of any change in the “CUSIP” number(s).

ARTICLE FOUR

SATISFACTION AND DISCHARGE

SECTION 401. Satisfaction and Discharge of Indenture.

This Indenture shall cease to be of further effect (subject to Section 1106 and except as to surviving rights of registration of transfer, transfer, exchange and replacement of Securities expressly provided for herein or pursuant hereto), the Liens, if any, on the Collateral securing the Securities and the Note Guarantees shall be released and the Trustee, at the request and expense of the Issuer, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture and release of such Liens, in each case, when

(1) either

(a) all Outstanding Securities have been delivered to the Trustee for cancellation; or

(b) all such Securities not theretofore delivered to the Trustee for cancellation

(i) have become due and payable, or

(ii) will become due and payable within one year, or

(iii) are to be called for redemption within one year under irrevocable arrangements satisfactory to the Trustee in its sole discretion for the giving of notice of redemption by the Trustee in the name and at the expense of the Issuer,

and the Issuer, in the case of (i), (ii) or (iii) above, has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Debt on the Securities not theretofore delivered to the Trustee for cancellation, for principal of (and premium, if any, on), and interest on, the Securities to Maturity or the Redemption Date, as the case may be;

(2) the Issuer has paid or caused to be paid all other sums payable by the Issuer hereunder; and

(3) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations under Sections 607 and 609 and, if money shall have been deposited with the Trustee pursuant to clause (1)(b) of this Section 401, the obligations of the Trustee under Section 402 and the last paragraph of Section 903 shall survive such satisfaction and discharge.

SECTION 402. Application of Trust Money.

Subject to the provisions of the last paragraph of Section 903, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

ARTICLE FIVE

REMEDIES

SECTION 501. Events of Default.

“Event of Default”, wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(7) the rendering of a judgment or judgments against Level 3 Parent, the Issuer or any Issuer Restricted Subsidiary in an aggregate amount in excess of $275,000,000 or its foreign currency equivalent at the time and shall not be waived, satisfied or discharged for any period of 60 consecutive days during which a stay of enforcement shall not be in effect; or

(8) any Note Guarantee of Level 3 Parent, Level 3 LLC or any other Guarantor that is either a Significant Subsidiary or a guarantor of any Existing Notes then outstanding, ceases to be in full force and effect (other than in accordance with the terms of such Note Guarantee) or Level 3 Parent, Level 3 LLC or any other Guarantor that is either a Significant Subsidiary or a guarantor of any Existing Notes then outstanding denies or disaffirms its obligations under its Note Guarantee; or

(9) the entry of a decree or order by a court having jurisdiction in the premises adjudging Level 3 Parent, the Issuer or any Issuer Restricted Subsidiary that is a Significant Subsidiary as bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of Level 3 Parent, the Issuer or any Issuer Restricted Subsidiary that is a Significant Subsidiary under the Federal Bankruptcy Code or any other applicable federal, state or foreign law,

or appointing a receiver, liquidator, assignee, trustee, custodian or sequestrator (or other similar official) of Level 3 Parent, the Issuer or any Issuer Restricted Subsidiary that is a Significant Subsidiary or of any substantial part of its Property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or

SECTION 502. Acceleration of Maturity; Noteholder Direction; Rescission and Annulment.

If an Event of Default (other than an Event of Default specified in Section 501(9) or 501(10) with respect to Level 3 Parent or the Issuer) shall occur and be continuing, either the Trustee or the Holders of not less than 30% in aggregate principal amount of the Outstanding Securities may declare the principal amount of all the Securities to be due and payable immediately, by a notice in writing to the Issuer (and to the Trustee if given by Holders), and upon any such declaration such principal amount shall become immediately due and payable; provided that a notice of Default may not be given with respect to any action taken, and reported publicly or to Holders, more than two years prior to such notice of Default. If an Event of Default specified in Section 501(9) or 501(10) occurs with respect to Level 3 Parent or the Issuer, the principal amount of all the Securities shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

Any Noteholder Direction provided by any Directing Holder must be accompanied by a Position Representation, which representation, in the case of a Default Direction, shall be deemed repeated at all times until the resulting Event of Default is cured or otherwise ceases to exist or the Securities are accelerated. In addition, each Directing Holder must, at the time of providing a Noteholder Direction, make a Verification Covenant. In any case in which the Holder is DTC or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the Securities in lieu of DTC or its nominee.

If, following the delivery of a Noteholder Direction, but prior to acceleration of the Securities, the Issuer determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officers’ Certificate stating that the Issuer has filed papers with or initiated litigation in a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any Event of Default that resulted from the applicable Noteholder Direction, the cure period with respect to such Event of Default shall be automatically stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Securities, the Issuer provides to the Trustee an Officers’ Certificate stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to any Event of Default that resulted from the applicable Noteholder Direction and any remedy shall be automatically stayed pending satisfaction of such Verification Covenant. Any breach of the Position Representation shall result in such Holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation of such Holder, the percentage of Securities held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Event of Default shall be deemed never to have occurred. The Trustee shall be deemed not to have received such Noteholder Direction or any notice of such Default or Event of Default. The Trustee shall be entitled to conclusively rely without liability on any Noteholder Direction delivered to it in accordance with this Section 502, shall have no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant, verify any statements in any Officers’ Certificate delivered to it, or otherwise make calculations, investigations or determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise and shall have no liability for ceasing to take any action or staying any remedy. The Trustee shall have no liability to the Issuer, any Holder or any other Person in acting in good faith on a Noteholder Direction or refraining from taking any action in good faith with respect thereto or to determine whether any Holder has delivered a Position Representation or that such Position Representation conforms with this Indenture or any other agreement and can rely conclusively on the Officers’ Certificate delivered by the Issuer and determinations made by a court of competent jurisdiction.

Notwithstanding anything in the preceding two paragraphs to the contrary, any Noteholder Direction delivered to the Trustee during the pendency of an Event of Default specified in Sections 501(9) or 501(10) shall not require compliance with the preceding two paragraphs.

At any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article Five, the Holders of a majority in aggregate principal amount of the Outstanding Securities, by written notice to the Issuer and the Trustee, may rescind and annul such declaration and its consequences if:

(1) the Issuer has paid or deposited with the Trustee a sum sufficient to pay

(A) all overdue interest on all Outstanding Securities,

(B) all unpaid principal of (and premium, if any, on) any Outstanding Securities which has become due otherwise than by such declaration of acceleration, and interest on such unpaid principal at the rate borne by the Securities,

(C) to the extent that payment of such interest is lawful, interest on overdue interest at the rate borne by the Securities, and

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

(2) all Events of Default, other than the nonpayment of amounts of principal of (or premium, if any, on) Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

The Issuer covenants that if:

(a) Default is made in the payment of any interest on any Security when due, continued for 30 days, or

(b) Default is made in the payment of the principal of (or premium, if any, on) any Security when due,

the Issuer will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Securities the whole amount then due and payable on such Securities for principal (and premium, if any) and interest, and interest on any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installment of interest, at the rate borne by the Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Issuer fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Issuer or any other obligor upon the Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Issuer or any other obligor upon the Securities, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504. Trustee May File Proofs of Claim.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Issuer or any other obligor upon the Securities (including Level 3 Parent and any other Guarantor) or the Property of the Issuer or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Issuer for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(i) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator or sequestrator (or other similar official) in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel, and any other amounts due the Trustee under Section 607.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or accept or adopt on behalf of, any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

SECTION 506. Application of Money Collected.

Any money collected by the Trustee pursuant to this Article Five shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 607;

SECOND: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest, respectively; and

THIRD: The balance, if any, to the Issuer or as a court of competent jurisdiction may direct.

SECTION 507. Limitation on Suits.

No Holder of any Securities shall have any right to institute any proceeding with respect to this Indenture or for any other remedy hereunder, unless

(1) such Holder shall have previously given to the Trustee written notice of a continuing Event of Default;

(2) the Holders of not less than 30% in aggregate principal amount of the Outstanding Securities shall have made written request and offered indemnity reasonably satisfactory to the Trustee to institute such proceeding as trustee; and

(3) the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the Outstanding Securities a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days;

it being understood and intended that no one or more Holders shall have any right in any manner whatsoever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders.

SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and Interest.

Notwithstanding any other provision in this Indenture, including Section 507, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment as provided herein (including, if applicable, Article Eleven) and in such Security of the principal of (and premium, if any) and interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

SECTION 509. Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Issuer, any Guarantor, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 510. Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 511. Delay or Omission Not Waiver.

Except as otherwise provided in the proviso of the first paragraph of Section 502, no delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article Five or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 512. Control by Holders.

The Holders of a majority in aggregate principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided that

(1) such direction shall not be in conflict with any rule of law or with this Indenture,

(2) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction, and

(3) the Trustee need not take any action which might involve it in personal liability or be unjustly prejudicial to the Holders not consenting.

SECTION 513. Waiver of Past Defaults.

The Holders of not less than a majority in principal amount of the Outstanding Securities may, on behalf of the Holders of all the Securities, waive any past Default hereunder and its consequences, except a Default

(1) in the payment of the principal of (or premium, if any) or interest on any Security, or

(2) in respect of a covenant or provision hereof which under Article Eight cannot be modified or amended without the consent of the Holder of each Outstanding Security affected, or

(3) in respect of the covenant contained in Section 915, which under Article Eight cannot be modified or amended without the consent of the Holders of two-thirds in principal amount of the Outstanding Securities.

The Issuer and Level 3 Parent shall deliver to the Trustee an Officers’ Certificate stating that the requisite majority have consented to such waiver and attaching such consents upon which, subject to Section 104, the Trustee may conclusively rely. Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon.

SECTION 514. Waiver of Stay or Extension Laws.

The Issuer and each Guarantor covenant (to the extent that they may lawfully do so) that they shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer and each Guarantor (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law and covenant that they shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 515. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorney’s fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 515 does not apply to a suit by the Trustee or a suit by Holders of more than 10% in principal amount of the then Outstanding Securities.

ARTICLE SIX

THE TRUSTEE

SECTION 601. Certain Duties and Responsibilities.

(a) Except during the continuance of an Event of Default,

(1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein).

(b) In case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that

(1) this paragraph (c) shall not be construed to limit the effect of paragraph (a) of this Section 601;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Securities relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; and

(4) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or indemnity reasonably satisfactory to it against such risk or liability is not reasonably assured to it.

(d) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 601.

SECTION 602. Notice of Default.

If a Default occurs and is continuing, the Trustee shall transmit, electronically or by first class mail to each Holder at the address set forth in the Security Register, notice of such Default within 90 days after written notice of it is received by a Responsible Officer of the Trustee; provided, however, that, except in the case of a Default in the payment of the principal of (or premium, if any) or interest on any Security, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders.

The Trustee is not required to take notice or deemed to have notice of any Event of Default with respect to the Securities unless a Responsible Officer of the Trustee shall have received written notice at its Corporate Trust Office (which notice shall reference the Securities, the Issuer and this Indenture) of such Event of Default from the Issuer or any Holder.

SECTION 603. Certain Rights of Trustee.

Subject to Section 601:

(1) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(2) any request or direction of the Issuer mentioned herein shall be sufficiently evidenced by an Issuer Request or Issuer Order and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution;

(3) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, receive and rely upon an Officers’ Certificate;

(4) the Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(5) the Trustee may act through counsel, agents, custodians and nominees and shall not be responsible for the misconduct or negligence of any such person appointed with due care and in good faith;

(6) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction;

(7) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer, personally or by agent or attorney at the expense of the Issuer and shall incur no liability of any kind by reason of such inquiry or investigation;

(10) the Trustee may request that Level 3 Parent or the Issuer deliver an Officers’ Certificate in substantially the form of Exhibit A hereto setting forth the names of individuals and titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded;

However, the Trustee must comply with Section 608.

SECTION 606. Money Held in Trust.

Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Issuer.

SECTION 607. Compensation and Reimbursement.

The Issuer agrees:

(1) to pay to the Trustee from time to time such compensation as shall be agreed in writing between the Issuer and the Trustee for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as shall be determined to have been caused by the Trustee’s own negligence, willful misconduct or bad faith; and

(3) to fully indemnify each of the Trustee and any predecessor trustee and its directors, officers, employees and agents for, and to hold them harmless against, any and all loss, liability, damage, claim or expense including taxes (other than taxes based on the income of the Trustee) incurred without negligence, willful misconduct or bad faith on the part of any of them, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself or themselves against any claim (whether asserted by the Issuer, a Guarantor, a Holder or any other Person) or liability in connection with the exercise or performance of any of its or their powers or duties hereunder.

When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(9) or (10), the expenses (including the reasonable charges and expenses of its counsel) of and the compensation for such services are intended to constitute expenses of administration under any applicable federal, state or foreign bankruptcy, insolvency or other similar law.

The provisions of this Section 607 shall survive the termination of this Indenture or the earlier resignation or removal of the Trustee.

SECTION 608. Corporate Trustee Required; Eligibility; Conflicting Interests.

(a) There shall be at all times a Trustee hereunder which shall have a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of federal, state, territorial or District of Columbia supervising or examining authority, then, for the purposes of this Section 608, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time a Responsible Officer of the Trustee shall have actual knowledge that the Trustee ceases to be eligible in accordance with the provisions of this Section 608, it shall resign immediately in the manner and with the effect hereinafter specified in this Article Six.

(b) The Trustee shall be permitted to engage in transactions with Level 3 Parent or its Subsidiaries; provided, however, that if the Trustee acquires any conflicting interest, the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the Commission for permission to continue acting as Trustee or (iii) resign.

SECTION 609. Resignation and Removal; Appointment of Successor.

(b) The Trustee may resign at any time by giving written notice thereof to the Issuer. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Issuer, any court of competent jurisdiction for the appointment of a successor Trustee.

(c) The Trustee may be removed at any time by Act of the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities, delivered to the Trustee and to the Issuer. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee designated for removal may petition, at the expense of the Issuer, any court of competent jurisdiction for the appointment of a successor Trustee.

(d) If at any time:

(1) the Trustee shall cease to be eligible under Section 608 and shall fail to resign after written request therefor by the Issuer or by any Holder who has been a bona fide Holder of a Security for at least six months, or

(2) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Issuer, by a Board Resolution (or by a resolution of a duly authorized committee of the Board of Directors of the Issuer), may remove the Trustee or (ii) the Holders of at least 10% in aggregate principal amount of the then Outstanding Securities who have been bona fide Holders of a Security for at least six months may, on behalf of themselves and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Issuer, by a Board Resolution, shall promptly appoint a successor Trustee. If the Issuer does not promptly appoint a successor Trustee after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in aggregate principal amount of the Outstanding Securities delivered to the Issuer and the retiring Trustee. In either case, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by the Issuer. If no successor Trustee shall have been so appointed by the Issuer or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

(f) The Issuer shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to the Holders of Securities in the manner provided for in Section 106. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

(g) The retiring Trustee shall not be liable for any of the acts or omissions of any successor Trustee appointed hereunder.

SECTION 610. Acceptance of Appointment by Successor.

Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Issuer and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Issuer or the successor Trustee, such retiring Trustee shall, upon payment of its charges hereunder, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Issuer shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts.

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article Six.

SECTION 611. Merger, Conversion, Consolidation or Succession to Business.

Any Person into which the Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder; provided that such Person shall be otherwise qualified and eligible under this Article Six, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion, consolidation or transfer of assets to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. In case at that time any of the Securities shall not have been authenticated, any successor Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides that the certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion, consolidation or transfer of assets.

ARTICLE NINE

COVENANTS

SECTION 901. Payment of Principal, Premium, if Any, and Interest.

The Issuer covenants and agrees for the benefit of the Holders that it shall duly and punctually pay the principal of (and premium, if any) and interest on the Securities in accordance with the terms of the Securities and this Indenture.

SECTION 902. Maintenance of Office or Agency.

The Issuer shall maintain in the City of New York an office or agency where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuer in respect of the Securities and this Indenture may be served. An affiliate of the Trustee, The Bank

of New York Mellon at 240 Greenwich St., New York, New York 10286, shall be such office or agency of the Issuer, unless the Issuer shall designate and maintain some other office or agency for one or more of such purposes. The Issuer shall give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at such affiliate’s office, and the Issuer hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

The Issuer may also from time to time designate one or more other offices or agencies (in or outside of the City of New York) where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain an office or agency in the City of New York for such purposes. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such other office or agency.

SECTION 903. Money for Security Payments to Be Held in Trust.

If the Issuer shall at any time act as its own Paying Agent, it shall, on or before each due date of the principal of (or premium, if any) or interest on any of the Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal of (or premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee of its action or failure so to act.

Whenever the Issuer shall have one or more Paying Agents for the Securities, it shall, on or before each due date of the principal of (or premium, if any) or interest on any Securities, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Issuer shall promptly notify the Trustee of such action or any failure so to act.

The Issuer shall cause each Paying Agent (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 903, that such Paying Agent shall:

(1) hold all sums held by it for the payment of the principal of, premium, if any, or interest on Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

(2) give the Trustee notice of any default by the Issuer (or any other obligor upon the Securities) in the making of any payment of principal, premium, if any, or interest;

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent; and

(4) indemnify the Trustee and its officers, directors, employees and agents against any loss, cost or liability caused by, or incurred as a result of, such Paying Agent’s acts or omissions.

The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Issuer Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Issuer or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Issuer or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest on any Security and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Issuer on Issuer Request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense of the Issuer cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the Borough of Manhattan, the City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Issuer.

SECTION 904. Existence.

Subject to Article Seven, Level 3 Parent and the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect the existence, rights (charter and statutory) and franchises of Level 3 Parent, the Issuer and each Issuer Restricted Subsidiary; provided, however, that Level 3 Parent and the Issuer shall not be required to preserve, with respect to Level 3 Parent or the Issuer, respectively, any such right or franchise or, with respect to any such Issuer Restricted Subsidiary (subject to all the other covenants in this Indenture), any such existence, right or franchise, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of Level 3 Parent and its Subsidiaries taken as a whole or the Issuer and its Subsidiaries taken as a whole, respectively.

SECTION 905. Reports.

So long as any Securities are outstanding (unless defeased in a legal defeasance), Level 3 Parent shall have its annual financial statements audited, and its interim financial statements reviewed, by a nationally recognized firm of independent accountants and shall furnish to the Trustee and the Holders of Securities, all quarterly and annual financial statements in the form incorporated by reference in the Offering Memorandum prepared in accordance with generally accepted accounting principles that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if Level 3 Parent was required to file those Forms (but in

no event any other items required in such Forms), together with a corresponding “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 Level 3 Parent’s certified independent accountant. Notwithstanding the foregoing, such reports shall not be required to (a) comply with any segment reporting requirements (whether pursuant to generally accepted accounting principles or Regulation S-X) in greater detail than is provided or incorporated by reference in the Offering Memorandum, (b) present beneficial ownership information; provided, however, that Level 3 Parent shall provide guarantor summary financial data substantially consistent with the data disclosed or incorporated by reference in the Offering Memorandum or (c) provide separate financial statements or other information contemplated by Rule 13-01 or Rule 13-02 of Regulation S-X. Any reports shall be provided within the time frames required by the Commission for companies required to file such reports on a non-accelerated basis. To the extent that Level 3 Parent does not file such information with the Commission, Level 3 Parent shall distribute such information and such reports (as well as the details regarding the conference call described below) electronically to the Trustee and either electronically or by posting such information on a website (which may be non-public, require a confidentiality acknowledgment and be maintained by Level 3 Parent or its designee) for the benefit of (a) any Holder of the Securities who provides its email address to Level 3 Parent, (b) to any beneficial owner of the Securities, who provides its email address to Level 3 Parent and certifies that it is a beneficial owner of Securities, (c) to any prospective investor who provides its email address to Level 3 Parent or its designee and certifies that it is a QIB, or (d) any securities analyst providing an analysis of investment in the Securities who provides its email address to Level 3 Parent and other information reasonably requested by Level 3 Parent and represents to the reasonable satisfaction of Level 3 Parent that (1) it is a bona fide securities analyst providing an analysis of investment in the Securities, (2) it will not use the information in violation of applicable securities laws or regulations, (3) it will keep such provided information confidential and will not communicate the information to any Person, (4) it will not use such information in any manner intended to compete with the business of Level 3 Parent or the Lumen Credit Group and (5) neither it nor its Affiliates is a Person that is principally engaged in a similar business or derives a significant portion of its revenues from operating or owning a similar business to that of Level 3 Parent or the Lumen Credit Group; provided that Level 3 Parent may deny access to any competitively-sensitive information otherwise to be provided pursuant to this Section 905 to the extent that Level 3 Parent determines in good faith that the provision of such information to such Person would be competitively harmful to Level 3 Parent or the Lumen Credit Group. Unless Level 3 Parent or Lumen is subject to the reporting requirements of the Exchange Act, Level 3 Parent shall also hold a quarterly conference call for the Holders of the Securities to discuss such financial information (which access may be limited in the manner described in this paragraph). The conference call will not be later than 10 Business Days from the time that Level 3 Parent distributes the financial information as set forth above.

For so long as any of the Securities remain outstanding, Level 3 Parent shall furnish to the Holders of the Securities and to any prospective investor that certifies that it is a QIB, upon written request, the information required to be delivered pursuant to Rule 144A(d)(4) promulgated under the Securities Act.

In the event that any direct or indirect parent of Level 3 Parent becomes a Guarantor or co-obligor of the Securities, Level 3 Parent may satisfy its obligations under this Section 905 with respect to financial information relating to Level 3 Parent by furnishing financial information relating to such parent.

Notwithstanding the foregoing, Level 3 Parent shall be deemed to have furnished such financial statements and reports referred to above to the Trustee and the Holders if Level 3 Parent or any direct or indirect parent of Level 3 Parent has filed such reports with the Commission via the EDGAR filing system (or any successor thereto) and such reports are publicly available.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute actual or constructive notice or knowledge of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

SECTION 906. Statement by Officers as to Default.

(a) The Issuer shall deliver to the Trustee, on the date of delivery of each annual report to be delivered pursuant to Section 905 commencing with the annual report for the fiscal year ended December 31, 2023, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Issuer’s compliance during the period covered by such report with all conditions and covenants under this Indenture. If the signer has knowledge of any noncompliance that occurred during such period, the certificate shall describe its status and what action the Issuer has taken or is taking or proposes to take with respect thereto. For purposes of this Section 906(a), such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

(b) When any Default has occurred and is continuing under this Indenture, or if the trustee for or the holder of any other evidence of Debt of the Issuer or any Issuer Restricted Subsidiary gives any notice or takes any other action with respect to a claimed default (other than with respect to Debt in the principal amount of less than $275,000,000 or its foreign currency equivalent at the time), the Issuer shall, within 30 days of such occurrence, notice or other action, deliver to the Trustee by registered or certified mail or by facsimile transmission an Officers’ Certificate specifying such event, notice or other action, its status and what action the Issuer is taking or proposes to take with respect thereto.

SECTION 907. Change of Control Triggering Event.

(a) Upon the occurrence of a Change of Control Triggering Event, each Holder shall have the right to require that the Issuer repurchase such Holder’s Securities in whole or in part in integral multiples of $1,000, in accordance with the procedures set forth in this Section 907 and this Indenture; provided, however, that no such partial repurchase shall reduce the portion of the principal amount of a Security not repurchased less than $2,000.

(b) Within 30 days following the occurrence of both a Change of Control and a Rating Decline with respect to the Securities (a “Change of Control Triggering Event”), or, at the Issuer’s option, prior to any Change of Control, but after the public announcement thereof, the Issuer will be required to make an Offer to Purchase all Outstanding Securities, unless the Issuer has issued a

notice to redeem all of the Securities as provided in Article Ten of this Indenture, at a price in cash equal to 101% of the principal amount of the Securities on the Purchase Date, plus accrued and unpaid interest (if any) to, but not including, such Purchase Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date). If delivered prior to the date of consummation of the Change of Control, the notice of such Offer to Purchase shall state that the Offer to Purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the payment date specified in such notice and may include other related conditions; provided, however, that no such condition shall relieve the Issuer from its repurchase obligation if a Change of Control Triggering Event in fact occurs.

(c) The Issuer and the Trustee shall perform their respective obligations for the Offer to Purchase as specified in the Offer. Prior to the Purchase Date, the Issuer shall (i) accept for payment Securities or portions thereof tendered pursuant to the Offer, (ii) irrevocably deposit with the Paying Agent (or, if the Issuer is acting as its own Paying Agent, segregate and hold in trust as provided in Section 903) money sufficient to pay the Purchase Price of all Securities or portions thereof so accepted (provided that such deposit may be made no later than 11:00 A.M. New York City time on the Purchase Date if the Issuer elects) and (iii) deliver or cause to be delivered to the Trustee all Securities so accepted together with an Officers’ Certificate stating the Securities or portions thereof accepted for payment by the Issuer. The Paying Agent shall promptly mail or deliver to Holders of Securities so accepted payment in an amount equal to the Purchase Price, and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Security or Securities equal in principal amount to any unpurchased portion of the Security surrendered as requested by the Holder. Any Security not accepted for payment shall be promptly mailed or delivered by the Issuer to the Holder thereof. In the event that the aggregate Purchase Price is less than the amount delivered by the Issuer to the Trustee or the Paying Agent, the Trustee or the Paying Agent, as the case may be, shall deliver the excess to the Issuer immediately after the Purchase Date.

(d) A “Change of Control” means the occurrence of any of the following events:

(i) if any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act or any successor provisions to either of the foregoing), including any group acting for the purpose of acquiring, holding, voting or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act, other than any one or more of the Permitted Holders, becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act, except that a person will be deemed to have “beneficial ownership” of all shares that any such person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of 50% or more of the total voting power of the Voting Stock of Level 3 Parent; or

(ii) the sale, transfer, assignment, lease, conveyance or other disposition, directly or indirectly, of all or substantially all the assets of Level 3 Parent, the Issuer and the Issuer Restricted Subsidiaries, in each case considered as a whole (other than a disposition of such assets as an entirety or virtually as an entirety to the Issuer, a Wholly Owned Restricted Subsidiary of the Issuer, Level 3 Parent or one or more Permitted Holders) shall have occurred; or

(iii) the shareholders of Level 3 Parent or the Issuer shall have approved any plan of liquidation or dissolution of Level 3 Parent or the Issuer, respectively.

Notwithstanding the preceding or any provision of Rule 13d-3 or 13d-5 under the Exchange Act, for purposes of this Indenture (i) a person or group shall not be deemed to beneficially own Voting Stock (x) subject to a stock or asset purchase agreement, merger agreement, option agreement, warrant agreement or similar agreement (or voting or option or similar agreement related thereto) until the consummation of the acquisition of the Voting Stock in connection with the transactions contemplated by such agreement or (y) as a result of veto or approval rights in any joint venture agreement, shareholder agreement or other similar agreement, (ii) if any group includes one or more Permitted Holders, the issued and outstanding Voting Stock of Level 3 Parent owned, directly or indirectly, by any Permitted Holders that are part of such group shall not be treated as being beneficially owned by such group or any other member of such group for purposes of determining whether a Change of Control has occurred and (iii) a person or group shall not be deemed to beneficially own the Voting Stock of another person as a result of its ownership of Voting Stock or other securities of such other person’s parent entity (or related contractual rights) unless it owns more than 50% of the total voting power of the Voting Stock entitled to vote for the election of directors of such parent.

(e) The Issuer shall not be required to make an Offer to Purchase upon a Change of Control Triggering Event if a third party, with the prior written consent of the Issuer, makes the Offer to Purchase in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to an Offer to Purchase made by the Issuer and purchases all Securities validly tendered and not withdrawn under such Offer to Purchase.

(f) In the event that the Issuer makes an Offer to Purchase the Securities, the Issuer shall comply with any applicable securities laws and regulations, including any applicable requirements of Section 14(e) of, and Rule 14e-1 under, the Exchange Act. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 907 by virtue thereof.

(g) Notwithstanding anything to the contrary herein, so long as (i) any of the Existing Notes are outstanding, if a Change of Control Triggering Event (as defined in the applicable indenture) has occurred under any of the indentures governing such Existing Notes or (ii) if any loans or commitments are outstanding under the Existing Issuer Credit Facility, if a Change of Control Triggering Event (as defined in the Existing Issuer Credit Facility) has occurred, a Change of Control Triggering Event with respect to the Securities shall also be deemed to have occurred.

SECTION 908. Limitation on Debt.

(a) The Issuer may not, and may not permit any Issuer Restricted Subsidiary to, directly or indirectly, Incur any Debt; provided, however, that (i) the Issuer or (ii) any Issuer Restricted Subsidiary that is a Guarantor and a Loan Proceeds Note Guarantor may incur any Debt if, after giving pro forma effect to such Incurrence and the receipt and application of the net proceeds thereof, no Default or Event of Default would occur as a consequence of such Incurrence or be continuing following such Incurrence and the Issuer Debt Ratio would be less than 5.75 to 1.0.

For purposes of determining compliance with this Section 908, (1) any Debt outstanding under the Existing Issuer Credit Facility and the Existing Secured Notes will be treated as Incurred on the Issue Date pursuant to clause (ii) of paragraph (b) of this Section 908 and (2) in the event that an item of Debt meets the criteria of more than one of the types of Debt described in the above clauses, the Issuer, in its sole discretion, may divide and classify (and, subject to clause (1) above, may later reclassify) such item of Debt and only be required to include the amount and type of such Debt in one of such clauses. When classifying multiple Incurrences of Debt on the same day, the Issuer may, in its sole discretion, specify the order of Incurrence of such Debt and need only give pro forma effect to the specified Incurrence (and any prior Incurrence) for purposes of classifying such specified Incurrence.

SECTION 909. Limitation on Priority Debt.

(a) The Issuer may not permit any Issuer Restricted Subsidiary that is a Domestic Restricted Subsidiary but is not a Guarantor and a Loan Proceeds Note Guarantor to, directly or indirectly, Incur any Debt; provided, however, that any Issuer Restricted Subsidiary that is a Domestic Restricted Subsidiary of the Issuer but is not a Guarantor and a Loan Proceeds Note Guarantor may Incur any Debt if, after giving pro forma effect to such Incurrence and the receipt and application of the net proceeds thereof, no Default or Event of Default would occur as a consequence of such Incurrence or be continuing following such Incurrence and the aggregate amount of Priority Debt would not exceed the Priority Debt Cap.

(b) Notwithstanding the foregoing limitation, an Issuer Restricted Subsidiary that is a Domestic Restricted Subsidiary but is not a Guarantor and a Loan Proceeds Note Guarantor may Incur any and all of the following (each of which shall be given independent effect), if it would be permitted to Incur such Debt pursuant to the following provisions of Section 908 without being or becoming a Guarantor:

(i) without duplication, Debt permitted to be Incurred pursuant to clauses (i), (iii), (iv), (v) (but only to the extent not incurred in anticipation of such Person becoming an Issuer Restricted Subsidiary or such merger or consolidation), (vii), (viii), (ix)(2), (x) and (xi) of Section 908(b);

(ii) without duplication, Debt permitted to be Incurred pursuant to Section 908(b)(vi), but limited, in the case of refinancing Debt under Section 908(b)(v), to Debt not incurred in anticipation of such Person becoming an Issuer Restricted Subsidiary or such merger or consolidation; and

(iii) without duplication, following a Collateral Release Ratings Event, any Finance Lease Obligation incurred in accordance with this Indenture and then outstanding in effect on the date of such Collateral Release Ratings Event and any Finance Lease Obligation incurred in respect thereof that would satisfy the requirements of a “refinancing” pursuant to Section 908(b)(vi).

(c) Notwithstanding any other provision of this Section 909, (A) the maximum amount of Debt the Domestic Restricted Subsidiaries of the Issuer may Incur pursuant to this Section 909 shall not be deemed to be exceeded due solely to the result of fluctuations in the exchange rates of currencies and (B) accrual of interest, accretion or amortization of original issue discount, the payment of interest on any Debt in the form of additional Debt with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock shall not be deemed to be an incurrence of Debt for purposes of this covenant.

(d) For purposes of determining any particular amount of Debt under this Section 909, (1) Guarantees, Liens or obligations with respect to letters of credit supporting Debt otherwise included in the determination of such particular amount shall not be included and (2) any Liens granted for the benefit of the Securities pursuant to the provisions referred to in Sections 910 or 911 shall not be treated as Debt. In the event that an item of Debt meets the

criteria of more than one of the types of Debt described in the above clauses, the Issuer, in its sole discretion, may divide and classify (and may later reclassify) such item of Debt and only be required to include the amount and type of such Debt in one of such clauses. When classifying multiple Incurrences of Debt on the same day, the Issuer may, in its sole discretion, specify the order of Incurrence of such Debt and need only give pro forma effect to the specified Incurrence (and any prior Incurrence) for purposes of classifying such specified Incurrence.

(e) Notwithstanding anything to the contrary herein, the provisions of this Section 909 shall continue to apply after Section 908 has been terminated in accordance with Section 917.

SECTION 910. Limitation on Liens Prior to a Collateral Release Ratings Event.

(a) The Issuer may not, and may not permit any Issuer Restricted Subsidiary to, directly or indirectly, Incur or suffer to exist any Lien on or with respect to any Property now owned or acquired after the Issue Date to secure any Debt other than:

(i) Liens existing on the Issue Date and securing Debt outstanding on the Issue Date, which in any event shall not include Liens securing the Parent Intercompany Note or the Existing Unsecured Notes;

(ii) Liens Incurred on or after the Issue Date:

(A) to secure Debt permitted to be Incurred pursuant to clause (i) or (ii) of Section 908(b) (or refinancing Debt Incurred pursuant to Section 908(b)(vi) in respect thereof);

(B) on Receivables, collections thereof and accounts established solely for the collection of such Receivables to secure Debt under Qualified Receivable Facilities permitted to be Incurred pursuant to Section 908(b)(ii) (or refinancing Debt Incurred pursuant to Section 908(b)(vi) in respect thereof);

(C) on cash to secure reimbursement obligations in respect of letters of credit permitted to be Incurred pursuant to Section 908(b)(ii) (or refinancing Debt Incurred pursuant to Section 908(b)(vi) in respect thereof); provided that the amount of such cash does not exceed 120% of the face amount of such letters of credit;

(D) on Property acquired after the Issue Date with the proceeds of Purchase Money Debt Incurred pursuant to Section 908(b)(ii) (or refinancing Debt Incurred pursuant to Section 908(b)(vi) in respect thereof) to secure such Purchase Money Debt; provided that any such Lien may not extend to any Property other than the Telecommunications/IS Assets installed, constructed, acquired, leased, developed or improved with the proceeds of such Purchase Money Debt and any improvements or accessions thereto (it being understood that all Debt to any single lender or group of related lenders or outstanding under any single credit facility, and in any case relating to the same group or collection of Telecommunications/IS Assets financed thereby, shall be considered a single Purchase Money Debt, whether drawn at one time or from time to time);

(E) on the Collateral to secure Debt Incurred pursuant to (A) clause (i) or (ii) of Section 908(b) or (B) Section 908(b)(vi) in respect of Debt previously Incurred pursuant to clause (i) or (ii) of Section 908(b); provided that such Liens are subject to the Intercreditor Agreement;

(iii) Liens in favor of the Issuer or any Issuer Restricted Subsidiary; provided, however, that any subsequent issue or transfer of Capital Stock or other event that results in any such Issuer Restricted Subsidiary ceasing to be an Issuer Restricted Subsidiary or any subsequent transfer of the Debt secured by any such Lien (except to the Issuer or an Issuer Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Lien by the issuer thereof;

(iv) Liens outstanding on the Issue Date securing Purchase Money Debt and Liens to secure Purchase Money Debt Incurred after the Issue Date and not prohibited by Section 908(b) and Section 909, provided that any such Lien may not extend to any Property other than the Telecommunications/IS Assets installed, constructed, acquired, leased, developed or improved with the proceeds of such Purchase Money Debt and any improvements or accessions thereto (it being understood that all Debt to any single lender or group of related lenders or outstanding under any single credit facility, and in any case relating to the same group or collection of Telecommunications/IS Assets financed thereby, shall be considered a single Purchase Money Debt, whether drawn at one time or from time to time);

(v) Liens to secure Acquired Debt, provided that (a) such Lien attaches to the acquired Property prior to the time of the acquisition of such Property and (b) such Lien does not extend to or cover any other Property;

(vi) Liens to secure Debt Incurred to refinance, in whole or in part, Debt secured by any Lien referred to in the foregoing clauses (i), (iv) and (v) or this clause (vi) so long as such Lien does not extend to any other Property (other than improvements and accessions to the original Property) and the principal amount of Debt so secured is not increased except as otherwise permitted under Section 908(b)(vi) or the corresponding provisions of Section 909;

(vii) Liens on Property (A) not constituting Collateral and (B) not required to become Collateral, Incurred on or after the Measurement Date not otherwise permitted by the foregoing clauses (i) through (vi) (but including in the computations of Liens permitted under this clause (vii) Liens existing on the Issue Date which remain existing at the time of computation which are otherwise permitted under clause (i)) securing Debt of the Issuer or any Issuer Restricted Subsidiary in an aggregate amount not to exceed the greater of (a) $500,000,000 and (b) 7.5% of the Issuer’s Consolidated Tangible Assets measured based on the most recent financial statements that are available for the Issuer;

(viii) Liens on Property of any Non-Telecommunications Subsidiary; provided, however, that the Incurrence of such Lien does not require the Person Incurring such Lien to secure any Debt of any Person other than a Non-Telecommunications Subsidiary;

(ix) Liens to secure Debt incurred pursuant to Section 908(b)(viii);

(x) Liens to secure amounts deposited into an escrow account for the benefit of the holders of the Existing Notes or any additional notes issued by the Issuer on or after the Issue Date permitted to be incurred pursuant to the terms of this Indenture, in connection with the prepayment of the Existing Proceeds Notes by Level 3 LLC, or the prepayment by Level 3 LLC of any additional proceeds note issued in connection with the issuance of additional notes issued by the Issuer on or after the Issue Date;

(xi) Liens (A) on the Property of a Foreign Restricted Subsidiary and its Subsidiaries Incurred on or after the Issue Date securing Debt of such Foreign Restricted Subsidiary and (B) on the Capital Stock of a Joint Venture securing Guarantees of the Debt of such Joint Venture Incurred on or after the Issue Date, in each case Incurred pursuant to Section 908(b)(ix); and

(xii) Permitted Liens.

(b) If the Issuer or any Guarantor (or any entity required to become a Guarantor pursuant to this Indenture) creates any Lien upon any Property or assets to secure any First Lien Obligation, it must concurrently with the creation of such Lien (or, if later, concurrently with such entity becoming a Guarantor) grant a First Lien upon such Property or assets as security for the Securities or the applicable Note Guarantee, if such Property or asset is not Collateral at such time, such that the property or assets subject to such Lien becomes Collateral subject to the First Lien (subject to liens permitted by this Indenture), except to the extent such Property or assets constitutes cash or cash equivalents required to secure only letter of credit obligations under any credit facility or as otherwise permitted under the Intercreditor Agreement. If the foregoing obligation to grant a Lien on any property or assets to secure the Securities or a Note Guarantee arises due to the grant of a Lien on such property or assets to secure the Existing Issuer Credit Facility Obligations (or the obligations under any Replacement Credit Facility), then the Lien on such property or assets to secure the Securities or a Note Guarantee may be released in accordance with the provisions of Section 1308. If the foregoing obligation to grant a Lien on any property or assets to secure the Securities or a Note Guarantee arises due to the grant of a Lien (an “Initial Lien”) on such property or assets to secure First Lien Obligations other than the Existing Issuer Credit Facility Obligations (or the obligations under any Replacement Credit Facility), then the Lien on such property or assets to secure the Securities or a Note Guarantee shall be automatically released and discharged upon the release and discharge of the Initial Lien at such time as the Initial Lien is released, which release and discharge in the case of any sale of any such property or asset shall not affect any Lien that the Trustee or any Collateral Agent may have on the proceeds from such sale.

(c) Notwithstanding the foregoing, the Issuer and the Guarantors shall not be deemed to have failed to comply with paragraph (b) of this Section 910 if, on the Issue Date, Level 3 Parent and each Issuer Restricted Subsidiary that has granted any Lien on any property or assets to secure the Existing Issuer Credit Facility Obligations and may grant a Lien on such property or assets as security for the Securities or the applicable Note Guarantee without regulatory approval, grants a First Lien upon such property or assets as security for the Securities or the applicable Note Guarantee such that the property or assets subject to such Lien becomes Collateral subject to the First Lien and, thereafter, until such date as the Collateral subject to the First Lien includes all property and assets in respect of which a Lien has been granted to secure the Existing Issuer Credit Facility, Level 3 Parent, the Issuer and any applicable Issuer Restricted Subsidiary (i) endeavor in good faith using commercially reasonable efforts to obtain all material (as determined in good faith by the General Counsel of Level 3 Parent) authorizations and consents of federal and state Governmental Authorities required in order for any such property or assets to secure the Securities at the earliest practicable date after the Issue Date and, following receipt of such authorizations and consents (together with any required authorizations and consents required for the Issuer Restricted Subsidiary owning such Collateral to provide a Note Guarantee), grants a First Lien upon such property or assets as security for the Securities or the applicable Note Guarantee such that the property or assets subject to such Lien becomes Collateral subject to the First Lien promptly thereafter and (ii) comply with paragraph (b) of this Section 910 with respect to any Lien attaching to property or assets subsequent to the Issue Date. For purposes of this paragraph (c), the requirement that Level 3 Parent, the Issuer or any Issuer Restricted Subsidiary use “commercially reasonable efforts” shall not be deemed to require it to make material payments in excess of normal fees and costs to or at the direction of Governmental Authorities or to change the manner in which it conducts its business in any respect that the management of Level 3 Parent shall determine in good faith to be adverse or materially burdensome. Upon the reasonable request of Level 3 Parent or the Issuer, the Trustee will use reasonable efforts to cooperate with Level 3 Parent, the Issuer and any Issuer Restricted Subsidiary as necessary to enable them to comply with their obligations under this paragraph (c).

(d) For purposes of determining compliance with this Section 910, in the event that a Lien meets the criteria of more than one of the types of Liens described in the above clauses, the Issuer, in its sole discretion, may divide and classify (and may later reclassify) such Lien and only be required to include the amount and type of such Lien in one of such clauses. When classifying multiple Incurrences of Liens on the same day, the Issuer may, in its sole discretion, specify the order of Incurrence of such Liens and need only give pro forma effect to the specified Incurrence (and any prior Incurrence) for purposes of classifying such specified Incurrence.

(e) Notwithstanding anything to the contrary herein, the provisions of this Section 910 shall continue to apply after Section 908 has been terminated in accordance with Section 917.

SECTION 911. Limitation on Liens Following a Collateral Release Ratings Event.

(a) Following a Collateral Release Ratings Event, the Issuer may not, and may not permit any Issuer Restricted Subsidiary to, directly or indirectly, Incur or suffer to exist any Lien on or with respect to any Property now owned or acquired after the Issue Date to secure any Debt for borrowed money without making, or causing such Issuer Restricted Subsidiary to make, effective provision for securing the Securities (x) equally and ratably with such Debt as to such Property for so long as such Debt will be so secured or (y) in the event such Debt is Debt of the Issuer or an Issuer Restricted Subsidiary that is a Guarantor and such Debt is subordinate in right of payment to the Securities, the Level 3 Parent Guarantee or the applicable Note Guarantee, prior to such Debt as to such Property for so long as such Debt will be so secured. The holders of such other secured Debt may exclusively control the disposition of the property subject to the Lien.

(b) The foregoing restrictions shall not apply to:

(i) Liens to secure Debt in an amount which, together (without duplication) with the aggregate principal amount of outstanding Priority Debt, does not exceed the Priority Debt Cap;

(ii) Liens to secure any Finance Lease Obligation incurred in accordance with this Indenture and then outstanding in effect on the date of such Collateral Release Ratings Event and any Finance Lease Obligation incurred in respect thereof that would satisfy the requirements of a “refinancing” pursuant to Section 908(b)(vi);

(iii) Liens in favor of the Issuer or any Issuer Restricted Subsidiary; provided, however, that any subsequent issue or transfer of Capital Stock or other event that results in any such Issuer Restricted Subsidiary ceasing to be an Issuer Restricted Subsidiary or any subsequent transfer of the Debt secured by any such Lien (except to an Issuer Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Lien by the issuer thereof;

(iv) Liens to secure Purchase Money Debt Incurred after the Issue Date and not prohibited by Section 908 and Section 909; provided that any such Lien may not extend to any Property other than the Telecommunications/IS Assets installed, constructed, acquired, leased, developed or improved with the proceeds of such Purchase Money Debt and any improvements or accessions thereto (it being understood that all Debt to any single lender or group of related lenders or outstanding under any single credit facility, and in any case relating to the same group or collection of Telecommunications/IS Assets financed thereby, shall be considered a single Purchase Money Debt, whether drawn at one time or from time to time);

(v) Liens to secure Acquired Debt; provided that (a) such Lien attaches to the acquired Property prior to the time of the acquisition of such Property and (b) such Lien does not extend to or cover any other Property;

(vi) Liens to secure Debt Incurred to refinance, in whole or in part, Debt secured by any Lien referred to in the foregoing clauses (iv) and (v) or this clause (vi) so long as such Lien does not extend to any other Property (other than improvements and accessions to the original Property) and the principal amount of Debt so secured is not increased except as otherwise permitted under Section 908(b)(vi) or the corresponding provisions of Section 909;

(vii) Liens on Property of any Non-Telecommunications Subsidiary;

(viii) Liens to secure Debt incurred pursuant to Section 908(b)(viii) or the corresponding provisions of Section 909;

(ix) Liens to secure amounts deposited into an escrow account for the benefit of the holders of the Existing Notes or any Additional Securities issued by the Issuer on or after the Issue Date permitted to be incurred pursuant to the terms of this Indenture, in connection with the prepayment of the Existing Proceeds Notes by Level 3 LLC, or the prepayment by Level 3 LLC of any additional proceeds note issued in connection with the issuance of Additional Securities issued by the Issuer on or after the Issue Date;

(x) Liens to secure amounts deposited into an escrow account for the benefit of the Holders of the Securities in connection with the prepayment of the Loan Proceeds Note by Level 3 LLC;

(xii) Liens on Receivables, collections thereof and accounts established solely for the collection of such Receivables to secure Debt under Qualified Receivable Facilities permitted to be Incurred pursuant to Section 908(b)(ii) (or refinancing Debt Incurred pursuant to Section 908(b)(vi) in respect thereof); and (xiii) Permitted Liens.

(c) For purposes of determining compliance with this Section 911, in the event that a Lien meets the criteria of more than one of the types of Liens described in the above clauses, the Issuer, in its sole discretion, may divide and classify (and may later reclassify) such Lien and only be required to include the amount and type of such Lien in one of such clauses. When classifying multiple Incurrences of Liens on the same day, the Issuer may, in its sole discretion, specify the order of Incurrence of such Liens and need only give pro forma effect to the specified Incurrence (and any prior Incurrence) for purposes of classifying such specified Incurrence.

(d) Notwithstanding anything to the contrary herein, the provisions of this Section 911 shall continue to apply after Section 908 has been terminated in accordance with Section 917.

SECTION 912. Limitation on Asset Dispositions.

(a) The Issuer may not, and may not permit any Issuer Restricted Subsidiary to, make any Asset Disposition consisting of Property that is Collateral unless the Issuer or the Issuer Restricted Subsidiary, as the case may be, receives consideration for such disposition at least equal to the Fair Market Value for the Property sold or disposed of as determined by the Issuer in good faith and evidenced by a resolution of the board of directors of the Issuer (or a duly authorized committee thereof) filed with the Trustee.

(b) The Net Available Proceeds (or any portion thereof) from Asset Dispositions may be applied by the Issuer or an Issuer Restricted Subsidiary, to the extent the Issuer or such Issuer Restricted Subsidiary elects (or is required by the terms of any Debt): (i) to the permanent repayment or reduction of Debt then outstanding under any First Lien Obligations to the extent such First Lien Obligations would require such application or prohibit payments pursuant to the

Offer to Purchase described in paragraph (c) of this Section 912 (other than Debt owed to the Issuer or any Affiliate of the Issuer); or (ii) to reinvest in Telecommunications/IS Assets (including by means of an Investment in Telecommunications/IS Assets by a Restricted Subsidiary with Net Available Proceeds received by the Issuer or another Issuer Restricted Subsidiary).

(c) Any Net Available Proceeds from an Asset Disposition not applied in accordance with paragraph (b) of this Section 912 within 540 days from the date of the receipt of such Net Available Proceeds, or with respect to Net Available Proceeds committed to be applied in accordance with paragraph (b) of this Section 912 during such 540-day period, not actually so applied within 365 days after such initial 540-day period, will constitute “Excess Proceeds”. When the aggregate amount of Excess Proceeds exceeds $200,000,000, the Issuer (or, in the case of Debt of Level 3 Parent required or permitted to be repurchased by Level 3 Parent, Level 3 Parent) will be required to make an Offer to Purchase with such Excess Proceeds on a pro rata basis according to principal amount (or, in the case of Debt issued at a discount, the then-Accreted Value) for (x) outstanding Securities at a price in cash equal to 100% of the principal amount of the Securities on the purchase date plus accrued and unpaid interest (if any) thereon (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date) and (y) any other First Lien Obligations of the Issuer, at a price no greater than 100% of the principal amount thereof plus accrued and unpaid interest (if any) to the purchase date (or 100% of the then-Accreted Value plus accrued and unpaid interest (if any) to the purchase date in the case of original issue discount Debt), to the extent, in the case of this clause (y), required under the terms thereof (other than Debt owed to Level 3 Parent or any Affiliate of Level 3 Parent). To the extent there are any remaining Excess Proceeds following the completion of the Offer to Purchase, the Issuer shall apply such Excess Proceeds to the repayment of other Debt of the Issuer or any Issuer Restricted Subsidiary, to the extent permitted or required under the terms thereof. Any other remaining Excess Proceeds may be applied to any use as determined by the Issuer which is not otherwise prohibited by this Indenture, and the amount of Excess Proceeds shall be reset to zero.

(d) Notwithstanding the foregoing, no Offer to Purchase the Securities or purchase of the Securities shall be required pursuant to this Section 912 unless either (i) the Existing Issuer Credit Facility and any secured Replacement Credit Facility has been retired or otherwise ceases to be in effect or (ii) such offer or purchase would not be prohibited by the Existing Issuer Credit Facility and any secured Replacement Credit Facility.

SECTION 913. Limitation on Sale and Leaseback Transactions.

The Issuer may not, and may not permit any Issuer Restricted Subsidiary to, directly or indirectly, enter into, assume, Guarantee or otherwise become liable with respect to any Sale and Leaseback Transaction, unless the Issuer or such Issuer Restricted Subsidiary would not be prohibited from Incurring (a) Debt in an amount equal to the Attributable Value of the Sale and Leaseback Transaction pursuant to Section 908 and (b) a Lien pursuant to Sections 910 or 911, as applicable, equal in amount to the Attributable Value of the Sale and Leaseback Transaction, without also securing the Securities.

SECTION 914. Limitation on Designations of Unrestricted Subsidiaries.

The Issuer shall not designate (1) Level 3 LLC as an Unrestricted Subsidiary under this Indenture or (2) any other Subsidiary of the Issuer (other than a newly created Subsidiary in which no investment has previously been made) as an “Unrestricted Subsidiary” under this Indenture (each, a “Designation”) unless:

(a) so long as any of the Existing Notes are outstanding, at the time of such Designation, such Subsidiary of the Issuer shall also be designated as an Unrestricted Subsidiary under each indenture governing the outstanding Existing Notes;

(b) so long as any loans or commitments are outstanding under the Existing Issuer Credit Facility or any other First Lien Obligation, at the time of such Designation, such Subsidiary of the Issuer shall also be designated as an Unrestricted Subsidiary under the Existing Issuer Credit Facility or such First Lien Obligation;

(c) no Default or Event of Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and

(d) (i) if Section 908 has not been terminated pursuant to Section 917, immediately prior to and after giving effect to such Designation, the Issuer would be able to Incur $1.00 of Debt under Section 908(a) or (ii) following termination of Section 908 pursuant to Section 917, immediately prior to and after giving effect to such Designation the aggregate amount of Priority Debt would not exceed the Priority Debt Cap.

At the time of any Designation of any Subsidiary as an Unrestricted Subsidiary, (i) such Subsidiary shall not own any Capital Stock of the Issuer or any Issuer Restricted Subsidiary and (ii) the Issuer or any Issuer Restricted Subsidiary shall not have guaranteed or otherwise have any direct payment obligations in respect of any Debt of such Subsidiary, except to the extent such guarantee or obligations would be released, terminated or no longer exist upon such Designation.

Unless Designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of the Issuer will be classified as an Issuer Restricted Subsidiary; provided, however, that such Subsidiary shall not be designated as an Issuer Restricted Subsidiary and shall be automatically classified as an Unrestricted Subsidiary if either of the requirements set forth in clauses (a) and (b) of the immediately following paragraph will not be satisfied immediately following such classification. Except as provided in the first sentence of this Section 914, no Issuer Restricted Subsidiary may be redesignated as an Unrestricted Subsidiary.

A Designation may be revoked (a “Revocation”) by a resolution of the Board of Directors of Level 3 Parent (or a duly authorized committee thereof) delivered to the Trustee, provided that the Issuer will not make any Revocation unless:

(a)

no Default or Event of Default shall have occurred and be continuing at the time of and after giving effect to such Revocation; and

(b)

all Liens and Debt of such Unrestricted Subsidiary outstanding immediately following such Revocation would, if Incurred at such time, have been permitted to be Incurred at such time for all purposes of this Indenture.

All Designations and Revocations must be evidenced by an Officers’ Certificate (i) certifying compliance with the foregoing provisions and (ii) giving the effective date of such Designation or Revocation. Upon Designation of a Restricted Subsidiary as an Unrestricted Subsidiary in compliance with this Section 914, such Restricted Subsidiary shall, by delivery of a supplemental indenture providing for such release in form satisfactory to the Trustee, be released from any Note Guarantee previously made by such Subsidiary in accordance with Section 1203.

SECTION 915. Limitation on Actions with Respect to Existing Intercompany Obligations. Without the consent of the Holders of at least two-thirds in principal amount of the Outstanding Securities:

(a) the Issuer shall not forgive or waive or fail to enforce any of its rights under any Existing Proceeds Note or any Guarantee thereof, the Loan Proceeds Note, any Loan Proceeds Note Guarantee, the Omnibus Existing Proceeds Note Subordination Agreement or any other agreement with Level 3 Parent or any Issuer Restricted Subsidiary to subordinate a payment obligation on any Debt to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note or a Loan Proceeds Note Guarantee, any Existing Proceeds Note or any Guarantee thereof and the Issuer and Level 3 LLC may not amend the Loan Proceeds Note, any Loan Proceeds Note Guarantee, any Existing Proceeds Note or any Guarantee thereof in a manner adverse to the Holders of the Securities; provided, however, that in the event of an Event of Default of Level 3 LLC specified in Section 501(9) or 501(10), the principal then outstanding together with accrued interest thereon under the Loan Proceeds Note, any Loan Proceeds Note Guarantee, any Existing Proceeds Note or any Guarantee thereof shall automatically become due and payable without presentment, demand, protest or other notice of any kind;

(b) in the event Level 3 LLC (or any successor obligor under the Loan Proceeds Note) repays all or a portion of the Loan Proceeds Note other than in connection with any refinancing of First Lien Obligations (and limited to the amount so refinanced), the Issuer must (i) deposit an amount of cash equal to the Pro Rata Portion multiplied by the principal amount of the Loan Proceeds Note then repaid in an escrow account with an unaffiliated financial institution for the benefit of the Holders of the Securities, and as security for the prompt and complete payment and performance when due of the Issuer’s obligations in respect of the Securities, until such time as the Securities are no longer outstanding or such cash is used pursuant to clause (ii) or (iii) of this paragraph (b), (ii) redeem Securities having a principal amount equal to the Pro Rata Portion multiplied by the principal amount of the Loan Proceeds Note then repaid in accordance with, and if at such time permitted by, the Securities, or (iii) purchase Securities in the open market having a principal amount equal to the Pro Rata Portion multiplied by the principal amount of the Loan Proceeds Note then repaid; provided, however, that if at any time the principal amount of the Loan Proceeds Note is greater than the principal amount of all First Lien Obligations that remain outstanding, Level 3 LLC (or any successor obligor under the Loan Proceeds Note) may repay, or the Issuer may forgive or waive, an amount of the Loan Proceeds Note equal to such excess without complying with clause (i), (ii) or (iii) above;

(c) Level 3 Parent shall not, and shall not permit any Issuer Restricted Subsidiary to, provide any Lien on its Property for the benefit of, or any Guarantee (other than a similarly subordinated Guarantee) or other form of credit enhancement in respect of, (i) the Parent Intercompany Note or (ii) any other intercompany note required by Section 908(b)(iv) to be subordinated to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note or a Loan Proceeds Note Guarantee, or take any other action with the purpose or effect of making the Parent Intercompany Note senior to or equal in right of payment with any Existing Proceeds Note or the Loan Proceeds Note;

(d) Level 3 Parent may not, and may not permit any Issuer Restricted Subsidiary to, provide any Lien on its Property for the benefit of, or any Guarantee (other than a similarly subordinated Guarantee) or other form of credit enhancement in respect of, (i) any Existing Proceeds Note or (ii) any other intercompany note required by Section 908(b)(iv) to be subordinated to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note or a Loan Proceeds Note Guarantee, or take any other action with the purpose or effect of making any Existing Proceeds Note senior to or equal in right of payment with the Loan Proceeds Note;

(e) Level 3 Parent and Level 3 LLC shall not amend the terms of the Parent Intercompany Note or any Existing Proceeds Note in a manner adverse to the Holders of the Securities, the determination of which shall be made by Level 3 Parent in good faith (it being agreed that any change in the interest rate applicable to advances under the Parent Intercompany Note shall not be deemed to be materially adverse to the Holders of the Securities in any respect);

(f) Level 3 Parent, the Issuer and Level 3 LLC shall not amend any subordination agreement relating to the Loan Proceeds Note in a manner adverse to the Holders of the Securities, and Level 3 Parent, the Issuer or any Issuer Restricted Subsidiary shall not amend any other agreement between Level 3 Parent or any Issuer Restricted Subsidiary and the Issuer to subordinate a payment obligation on any Debt of Level 3 Parent or any Issuer Restricted Subsidiary to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note, in each case, the determination of which shall be made by Level 3 Parent in good faith;

(g) unless an Event of Default has occurred and is continuing, Level 3 Parent shall neither cause nor permit the Issuer to demand repayment of any Existing Proceeds Note (i) prior to the Regulated Subsidiaries receiving the consents and authorizations described herein and (ii) unless permitted pursuant to all other First Lien Obligations;

(h) Level 3 Parent and the Issuer shall cause any Debt of Level 3 LLC to Level 3 Parent to be evidenced by either the Parent Intercompany Note or another duly executed promissory note that is pledged and delivered to the Note Collateral Agent (or any Bailee Collateral Agent) within three business days of the Incurrence of such Debt; and

(i) notwithstanding anything to the contrary contained herein, neither the Issuer nor Level 3 LLC (nor any successor obligor under the Loan Proceeds Note) shall cause or permit the principal amount of the Loan Proceeds Note at any time to be less than the aggregate principal amount of First Lien Obligations outstanding at such time (after giving effect to any substantially concurrent repayment or prepayment of any First Lien Obligations at the time of any reduction in the principal amount of the Loan Proceeds Note).

Each Subsidiary that is required to become a Loan Proceeds Note Guarantor pursuant to any Section of this Indenture shall promptly execute, and deliver a copy to the Trustee, a Loan Proceeds Note Guarantee substantially in the form set forth in Exhibit C hereto, pursuant to which such Subsidiary shall become a Loan Proceeds Note Guarantor.

The Loan Proceeds Note Guarantee of a Loan Proceeds Note Guarantor will be automatically and unconditionally released (a) in connection with any sale or other disposition of all or substantially all of the assets of that Loan Proceeds Note Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Issuer or an Issuer Restricted Subsidiary, such that after such transaction, such Loan Proceeds Note Guarantor would no longer constitute an Issuer Restricted Subsidiary, and, in each case, such sale, exchange, disposition or other transfer is made in compliance with all applicable provisions of this Indenture, if any, and such Person is not a guarantor of any First Lien Obligation, (b) in connection with any sale of all of the Capital Stock of a Loan Proceeds Note Guarantor to a Person that is not (either before or after giving effect to such transaction) the Issuer or an Issuer Restricted Subsidiary in compliance with all applicable provisions of this Indenture, if any, and such Person is not a guarantor of any First Lien Obligation, (c) if the Issuer properly designates any Issuer Restricted Subsidiary that is a Loan Proceeds Note Guarantor as an Unrestricted Subsidiary pursuant to Section 914, (d) if the Issuer exercises under Section 1101 of the option applicable to Sections 1102 or 1103, (e) if such Loan Proceeds Note Guarantee was originally Incurred to permit such Loan Proceeds Note Guarantor to Incur Debt not otherwise permitted pursuant to Sections 908 or 909 and the Debt so Incurred (and any permitted refinancing Debt thereof) has been repaid or discharged (provided that, after giving effect to such release, such Loan Proceeds Note Guarantor does not have any outstanding Debt that would violate such Sections if such outstanding Debt would have been Incurred following the release of such Loan Proceeds Note Guarantee and such Loan Proceeds Note Guarantor is not a Guarantor under any First Lien Obligation (other than the Securities)) or (f) if such Loan Proceeds Note Guarantor is released from its Loan Proceeds Note Guarantee and its other guarantees of all First Lien Obligations (other than the Securities) except any such release by or as a result of payment of such Loan Proceeds Note Guarantee and such Loan Proceeds Note Guarantor is not a guarantor under any of the Existing Notes and is not otherwise required to Guarantee the Securities in accordance with Section 916(a) or the last paragraph of Section 919.

SECTION 916. Limitation on Guarantees of Debt by Issuer Restricted Subsidiaries.

(a) Level 3 Parent shall not permit any Issuer Restricted Subsidiary, other than a Guarantor or the Issuer, to guarantee the payment of any First Lien Obligations, including any Debt (or any other Obligations) under the Existing Issuer Credit Facility, any Replacement Credit Facility, any of the Existing Notes or any of the Existing Proceeds Notes, unless:

(i) such Issuer Restricted Subsidiary within 30 days executes and delivers a supplemental indenture to this Indenture providing for a Note Guarantee or a guarantee of the Loan Proceeds Note, as applicable, by such Issuer Restricted Subsidiary, except that with respect to a guarantee of Debt of the Issuer or any Guarantor, if such Debt is by its express terms subordinated in right of payment to the Securities or such Guarantor’s Note Guarantee, any such guarantee by such Issuer Restricted Subsidiary with respect to such Debt shall be subordinated in right of payment to such Note Guarantee substantially to the same extent as such Debt is subordinated to the Securities;

(ii) in the case of Level 3 LLC, Level 3 LLC delivers to the Trustee an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized, executed and delivered by Level 3 LLC; and subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Note Guarantee of Level 3 LLC is a legal, valid and binding obligation of Level 3 LLC, enforceable against Level 3 LLC in accordance with its terms; and

(iii) if required pursuant to the terms of this Indenture to pledge any Property to secure its Note Guarantee, such Issuer Restricted Subsidiary delivers to the Note Collateral Agent all instruments and documents as the Note Collateral Agent may request or as may be necessary or proper to create and perfect a security interest in such Property for the benefit of the Holders of the Securities and the Note Collateral Agent or its bailee.

(b) Notwithstanding the foregoing paragraph (a) of this Section 916, Level 3 Parent shall not be deemed to have failed to comply with such paragraph (a) if, on the Issue Date, Level 3 Parent and each Issuer Restricted Subsidiary that guarantees the Existing Issuer Credit Facility and may provide a Note Guarantee without regulatory approval, provides a Note Guarantee and, thereafter, until such date as the Securities are guaranteed by each Issuer Restricted Subsidiary that guarantees any First Lien Obligation, Level 3 Parent, the Issuer and any applicable Issuer Restricted Subsidiary (i) endeavor in good faith using commercially reasonable efforts to obtain all material (as determined in good faith by the General Counsel of Level 3 Parent) authorizations and consents of federal and state Governmental Authorities required in order for any Issuer Restricted Subsidiary that guarantees the Existing Issuer Credit Facility but has not provided a Note Guarantee to provide a Note Guarantee at the earliest practicable date after the Issue Date and to enter into a Note Guarantee and, in the case of Level 3 LLC, provide an Opinion of Counsel complying with clause (ii) of paragraph (a) of this Section 916 promptly thereafter and (ii) comply with such paragraph (a) with respect to any Issuer Restricted Subsidiary that first guarantees the payment of any First Lien Obligations, including any Existing Issuer Credit Facility Obligations, subsequent to the Issue Date. For purposes of this paragraph (b), the requirement that Level 3 Parent, the Issuer or any Issuer Restricted Subsidiary use “commercially reasonable efforts” shall not be deemed to require it to make material payments in excess of normal fees and costs to or at the direction of Governmental Authorities or to change the manner in which it conducts its business in any respect that the management of Level 3 Parent shall determine in good faith to be adverse or materially burdensome. Upon the reasonable request of Level 3 Parent or the Issuer, the Trustee will use reasonable efforts to cooperate with Level 3 Parent, the Issuer and any Issuer Restricted Subsidiary as necessary to enable them to comply with their obligations under this paragraph (b).

SECTION 917. Covenant Termination.

SECTION 918. Collateral and Guarantee Termination.

If on any date following the Issue Date (i) either the Issuer or Level 3 Parent has obtained a corporate family rating or the equivalent (which may include a prospective corporate family rating or the equivalent reflecting the pro forma effect of a proposed transaction or series of related and substantially concurrent transactions) by two or more of the Rating Agencies that reflect an Investment Grade Rating (provided, however, that if neither the Issuer nor Level 3 Parent has been assigned a corporate family rating or the equivalent by a Rating Agency, a corporate family rating or the equivalent of any direct or indirect parent entity of Level 3 Parent by such Rating Agency may be substituted for the corporate family rating or the equivalent of the Issuer or Level 3 Parent for purposes of this clause (i)), (ii) all Collateral has been released (or shall be released substantially concurrently with the release of Collateral securing the Securities described in this paragraph) with respect to all First Lien Obligations (other than the Securities) and (iii) no Default or Event of Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i), (ii) and (iii) being collectively referred to as a “Collateral Release Ratings Event”), all Collateral securing the Securities shall be released in accordance with the terms set forth in this Indenture and the Note Collateral Documents. Concurrently with the release of Collateral upon a Collateral Release Ratings Event, the Guarantees of each Guarantor (other than Level 3 Parent and Level 3 LLC) with respect to the Securities shall be automatically and unconditionally released. For the avoidance of doubt, the occurrence of a Collateral Release Ratings Event shall not relieve any Person from any obligation under this Indenture to pledge Property to secure or to guarantee the Securities arising after such Collateral Release Ratings Event, including pursuant to Sections 909, 911 or 916. In addition, following a Collateral Release Ratings Event, (i) Section 909 shall be modified as set forth therein and in the definition of “Priority Debt Cap”, (ii) the Issuer and the Issuer Restricted Subsidiaries shall not be subject to Section 910 but shall thereafter be subject to Section 911 and (iii) the Issuer and the Issuer Restricted Subsidiaries shall not be subject to Section 912.

SECTION 919. Authorizations and Consents of Governmental Authorities.

Each of Level 3 Parent and the Issuer will endeavor, and cause Level 3 LLC to endeavor, in good faith using commercially reasonable efforts to cause Level 3 LLC and each other Regulated Subsidiary to obtain all material (as determined in good faith by the General Counsel of Level 3 Parent) authorizations and consents of federal and state Governmental Authorities

required in order for, at the earliest practicable date, (i) its equity to be pledged (other than Global Crossing Telecommunications, Inc.), (ii) it to Guarantee the Securities and pledge Collateral to secure such Guarantee and (iii) it to enter into a Guarantee of the Securities and pledge of Collateral promptly thereafter. For purposes of this covenant, the requirement that Level 3 Parent, the Issuer or Level 3 LLC use “commercially reasonable efforts” shall not be deemed to require it to make material payments in excess of normal fees and costs to or at the direction of Governmental Authorities or to change the manner in which they conduct their business in any respect that the management of Level 3 Parent shall determine in good faith to be adverse or materially burdensome. Upon the reasonable request of Level 3 Parent or the Issuer, the Trustee will use reasonable efforts to cooperate with Level 3 Parent, the Issuer and any Issuer Restricted Subsidiary as necessary to enable them to comply with their obligations under this paragraph.

Notwithstanding anything to the contrary contained herein (but subject to the following paragraph), if a Person is required to become a Guarantor pursuant to this Indenture, none of the Issuer or any Subsidiary shall be required to submit any application or filing or otherwise take any action to obtain any authorization or consent of any federal or state Governmental Authority required in order to cause such Person to become a Guarantor (and the requirement to provide such a Guarantee shall be tolled), in each case, to the extent an authorization or consent of such federal or state Governmental Authority is determined by Lumen, Level 3 Parent or the Issuer to be sought in respect of any Material Transaction or any financing relating thereto and has not yet been obtained; provided that (i) such Person is not submitting any application or filing or otherwise taking any action to obtain any authorization or consent of any federal or state Governmental Authority required in order to cause such Person to Guarantee any First Lien Obligation and (ii) at the time such federal or state Governmental Authority has approved such Material Transaction, the application, filing or other action to obtain any such authorization or consent of any federal or state Governmental Authority required in order to cause any Person to become a Guarantor shall promptly be made.

Subject in the case of a Regulated Subsidiary to the receipt of such authorizations and consents of federal and state Governmental Authorities as are required in order for such Regulated Subsidiary to guarantee the Securities and pledge Collateral to secure such Guarantee, notwithstanding anything to the contrary herein, no Issuer Restricted Subsidiary shall guarantee any of the Existing Notes or any First Lien Obligations (other than the Securities) unless such Issuer Restricted Subsidiary (i) is or becomes a Guarantor on the date on which such other Guarantee is Incurred, which Guarantee will be pari passu in right of payment with such Issuer Restricted Subsidiary’s Guarantee of such Existing Notes or First Lien Obligations (other than the Securities) and shall remain in effect for so long as such Issuer Restricted Subsidiary guarantees any Existing Notes or any First Lien Obligation (other than the Securities) and (ii) executes and delivers to the Trustee, substantially concurrently therewith, a supplement or joinder to, and as applicable, an amendment, restatement, supplement or other modification of, the Note Collateral Documents and takes all actions required thereunder to perfect the Liens created thereunder.

ARTICLE TEN

REDEMPTION OF SECURITIES

SECTION 1001. Right of Redemption.

The Securities will be subject to redemption at the option of the Issuer, in whole or in part, at any time or from time to time, upon not less than 10 nor more than 60 days’ prior notice, on the terms and at the Redemption Prices (expressed as percentages of principal amount) set forth in Section 5 on the reverse of the form of Security, plus accrued and unpaid interest thereon (if any) to, but not including, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date).

SECTION 1002. Applicability of Article.

This Article Ten shall govern any redemption of the Securities pursuant to Section 1001.

SECTION 1003. Election to Redeem; Notice to Trustee.

The election of the Issuer to redeem any Securities pursuant to Section 1001 shall be evidenced by a Board Resolution of the Issuer. The Issuer shall, at least 30 days prior to the Redemption Date fixed by the Issuer (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 1004. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Issuer to the effect that such redemption will comply with the conditions herein.

SECTION 1004. Selection by Trustee of Securities to Be Redeemed.

If less than all the Securities are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities not previously called for redemption, on a pro rata basis or by lot and, in the case of Securities represented by a Global Security held by the Depository, in accordance with Depository procedures; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than $2,000.

The Trustee shall promptly notify the Issuer in writing of all available information (including information obtainable from the Depository) concerning the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

SECTION 1005. Notice of Redemption.

Notice of redemption shall be given in the manner provided for in Section 106 not less than 10 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed; provided that in the case of Securities held through the Depository by Depository participants, such notice will be submitted via the Depository’s electronic messaging system.

Each notice of redemption shall identify the Securities (including “CUSIP” number(s) and the statement from Section 310) to be redeemed and shall state:

(1) the Redemption Date,

(2) the Redemption Price and the amount of accrued interest to, but not including, the Redemption Date payable as provided in Section 1007, if any,

(3) if relevant, any conditions to such redemption and the information required with respect thereto pursuant to Section 5 on the reverse of the form of Security,

(4) if less than all Outstanding Securities are to be redeemed, the identification (and, in the case of a partial redemption, the principal amounts) of the particular Securities to be redeemed,

(5) in case any Security is to be redeemed in part only, that on and after the Redemption Date, upon surrender of such Security, the Holder will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed,

(6) that on the Redemption Date the Redemption Price (and unpaid and accrued interest, if any, to, but not including, the Redemption Date payable as provided in Section 1007) will become due and payable upon each such Security, or the portion thereof, to be redeemed, and that, unless the Issuer defaults in making such redemption payment or the Trustee or the Paying Agent is prohibited from making such payment, interest thereon will cease to accrue on and after said date, and

(7) the place or places where such Securities are to be presented and surrendered for payment of the Redemption Price and accrued interest, if any.

Notice of redemption of Securities to be redeemed at the election of the Issuer shall be given by the Issuer or, at the Issuer’s request, by the Trustee in the name and at the expense of the Issuer; provided, however, in the latter case the Issuer shall give the Trustee at least 10 days prior notice (or such shorter notice as the Trustee may permit) of the date of the giving of the notice.

SECTION 1006. Deposit of Redemption Price.

On or prior to any Redemption Date (and if on any Redemption Date, before 11:00 A.M. New York City time, on such date), the Issuer shall deposit with the Trustee or with a Paying Agent (or, if the Issuer is acting as its own Paying Agent, segregate and hold in trust as provided in Section 903) an amount of money sufficient to pay the Redemption Price of, and unpaid and accrued interest (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date) on, all the Securities which are to be redeemed on that date.

100

SECTION 1007. Securities Payable on Redemption Date.

Notice of redemption having been given as aforesaid, subject to the satisfaction or waiver of any conditions set forth in such notice of redemption in accordance with Section 5 on the reverse form of the Security, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified (together with unpaid and accrued interest, if any, to, but not including, the Redemption Date), and from and after such date (unless the Issuer shall default in the payment of the Redemption Price and accrued interest or the Trustee or the Paying Agent shall be prohibited from making such payment) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Issuer at the Redemption Price, together with unpaid and accrued interest, if any, to, but not including, the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant record dates according to their terms.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Securities.

If the Issuer has given notice of redemption as provided in this Indenture and made available funds for the redemption of the Securities (or any portion thereof) called for redemption on or prior to the Redemption Date referred to in such notice, those Securities will cease to bear interest on or after that Redemption Date and the only right of the Holders of those Securities will be to receive payment of the Redemption Price, together with any accrued and unpaid interest.

SECTION 1008. Securities Redeemed in Part.

Any Security which is to be redeemed only in part shall be surrendered at the office or agency of the Issuer maintained for such purpose pursuant to Section 902 (with, if the Issuer and the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuer and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Issuer shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

ARTICLE ELEVEN

DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1101. Issuer’s Option to Effect Defeasance or Covenant Defeasance.

The Issuer may, at its option by Board Resolution of the Issuer, at any time, with respect to the Securities, elect to have either Section 1102 or Section 1103 be applied to all Outstanding Securities upon compliance with the conditions set forth below in this Article Eleven.

SECTION 1102. Defeasance and Discharge.

Upon the Issuer’s exercise under Section 1101 of the option applicable to this Section 1102, the Issuer and the Guarantors shall be deemed to have been discharged from their obligations with respect to all Outstanding Securities on the date the conditions set forth in Section 1104 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Issuer shall be deemed to have paid and discharged the entire indebtedness represented by the Outstanding Securities, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 1105 and the other Sections of this Indenture referred to in clauses (A) and (B) below, and to have satisfied all their other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (A) the Issuer’s obligations with respect to such Securities under Section 2.3 of Appendix A and Sections 303, 306, 307, 902 and 903 and the Issuer’s rights under Section 1001, (B) rights of Holders to receive payment of principal of, premium, if any, and interest on such Securities (but not the Purchase Price referred to under Section 907) and any rights of the Holders with respect to such amounts, (C) the rights, obligations and immunities of the Trustee under this Indenture and (D) this Article Eleven. Subject to compliance with this Article Eleven, the Issuer may exercise its option under this Section 1102 notwithstanding the prior exercise of its option under Section 1103 with respect to the Securities. If the Issuer exercises its option under this Section 1102, (v) each Guarantor, if any, shall be released from all its obligations under its Note Guarantee, (w) the Loan Proceeds Note may be prepaid in whole or in part, (x) no entity shall be obligated to guarantee the Loan Proceeds Note, (y) the Loan Proceeds Note may be canceled and (z) all obligations to provide Loan Proceeds Note Guarantees shall terminate and all references in this Indenture to Loan Proceeds Note Guarantees and Loan Proceeds Note Guarantees shall be disregarded and not be deemed to be requirements to take or omit to take any action by Level 3 Parent or any Restricted Subsidiary. Upon the Issuer’s exercise under Section 1101 of the option applicable to this Section 1102, all Liens on the Collateral securing the Debt evidenced by the Securities shall be released and the Note Collateral Documents shall cease to be of further effect.

SECTION 1103. Covenant Defeasance.

Upon the Issuer’s exercise under Section 1101 of the option applicable to this Section 1103, the Issuer and each Guarantor shall be released from their obligations under any covenant contained in Sections 701(a)(2), 703(a)(3), (4) and (5), in Sections 704, 706, 905 and 919 and Sections 907 through 917 and from the operation of Sections 501(6), (7), (8), (9), (10) and (11) (but, in the case of Sections 501(9) and (10), with respect only to Significant Subsidiaries), with respect to the Outstanding Securities on and after the date the conditions set forth below are satisfied (hereinafter, “covenant defeasance”), and the Securities shall thereafter be deemed not to be “Outstanding” for the purposes of any direction, waiver, consent, declaration or other Act of Holders (and the consequences of any thereof) in connection with such provisions, but shall continue to be deemed “Outstanding” for all other purposes hereunder.

102

For this purpose, such covenant defeasance means that, with respect to the Outstanding Securities, the Issuer and the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such provision, whether directly or indirectly, by reason of any reference elsewhere herein to any such provision or by reason of any reference in any such provision to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 501(3), (4), (5), (6), (7), (8), (9), (10) or (11) (but, in the case of Section 501(9) or (10), with respect only to Significant Subsidiaries) but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. If the Issuer exercises its option under this Section 1103, (v) each Guarantor shall be released from all its obligations under its Note Guarantee, (w) the Loan Proceeds Note may be prepaid in whole or in part, (x) no entity shall be obligated to guarantee the Loan Proceeds Note, (y) the Loan Proceeds Note may be canceled and (z) all obligations to provide Loan Proceeds Note Guarantees shall terminate and all references in this Indenture to Loan Proceeds Note Guarantees and Loan Proceeds Note Guarantees shall be disregarded and not be deemed to be requirements to take or omit to take any action by Level 3 Parent or any Restricted Subsidiary. Upon the Issuer’s exercise under Section 1101 of the option applicable to this Section 1103, all Liens on the Collateral securing the Debt evidenced by the Securities shall be released and the Note Collateral Documents shall cease to be of further effect.

SECTION 1104. Conditions to Defeasance or Covenant Defeasance.

The following shall be the conditions to application of either Section 1102 or Section 1103 to the Outstanding Securities:

(1) The Issuer shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 608 who shall agree to comply with the provisions of this Article Eleven applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, at any time prior to the Maturity of the Securities: (A) money in an amount, or (B) Government Securities which through the payment of interest and principal will provide, not later than one day before the due date of payment in respect of the Securities, money in an amount, or (C) a combination thereof, sufficient, in the opinion of a certified public accountant (selected by the Issuer or Level 3 Parent in its sole discretion) expressed in a written certification delivered to the Trustee, to pay and discharge the principal of (and premium, if any, on) and interest on, the Outstanding Securities on the Stated Maturity (or Redemption Date, if applicable) of such principal (and premium, if any) or installment of interest; provided that the Trustee (or such other trustee) shall have been irrevocably instructed in writing to apply such money or the proceeds of such Government Securities to said payments with respect to the Securities. Before such a deposit, the Issuer may give to the Trustee, in accordance with Section 1003, a notice of their election to redeem all of the Outstanding Securities at a future date in accordance with Article Ten, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing.

103

(2) No Default or Event of Default with respect to the Securities shall have occurred and be continuing on the date of such deposit or, insofar as Section 501(9) and Section 501(10) are concerned with respect to Level 3 Parent and the Issuer, at any time during the period ending on the 123rd day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period).

(3) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Issuer or any Guarantor is a party or by which it is bound.

(4) In the case of an election under Section 1102, the Issuer shall have delivered to the Trustee an Opinion of Counsel stating that (x) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling, or (y) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the Outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred.

(5) In the case of an election under Section 1103, the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the Outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred.

(6) The Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the defeasance under Section 1102 or the covenant defeasance under Section 1103 (as the case may be) have been complied with.

SECTION 1105. Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions.

Subject to the provisions of the last paragraph of Section 903, all money and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1105, the “Trustee”) pursuant to Section 1104 in respect of the Outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law or to the extent the Issuer or Level 3 Parent acts as the Issuer’s Paying Agent.

The Issuer shall pay and indemnify the Trustee and (if applicable) its officers, directors, employees and agents against any tax, fee or other charge imposed on or assessed against the Government Securities deposited pursuant to Section 1104 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Securities.

104

Anything in this Article Eleven to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon the Issuer’s Request any money or Government Securities held by it as provided in Section 1104 which, in the opinion of a certified public accountant (selected by the Issuer or Level 3 Parent in its sole discretion) expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance, as applicable, in accordance with this Article Eleven.

SECTION 1106. Reinstatement.

If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 401 or 1105 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s and each Guarantor’s obligations under the Note Documents shall be revived and reinstated as though no deposit had occurred pursuant to Section 401, 1102 or 1103, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance therewith; provided, however, that if the Issuer or any Guarantor makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the Issuer or such Guarantor shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE TWELVE

NOTE GUARANTEES

SECTION 1201. Guarantees. Each Guarantor hereby unconditionally guarantees, jointly and severally, to each Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of (and premium, if any) and interest on the Securities when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Issuer under the Note Documents and (b) the full and punctual performance within applicable grace periods of all other obligations of the Issuer under the Note Documents (all the foregoing being hereinafter collectively called the “Obligations”). Each Guarantor further agrees that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Guarantor, and that such Guarantor will remain bound under this Article Twelve notwithstanding any extension or renewal of any Obligation.

Each Guarantor waives presentation to, demand of, payment from and protest to the Issuer of any of the Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Obligations. The obligations of each Guarantor hereunder shall not be affected by (a) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Issuer or any other Person under this Indenture, the Securities or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Obligations of any of them; (e) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Obligations; or (f) any change in the ownership of such Guarantor.

105

Each Guarantor further agrees that its Note Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Obligations.

Except as expressly set forth in Sections 705, 706, 914, 1102, 1103, 1203 and 1208, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any terms thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

Each Guarantor further agrees that its Note Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of (or premium, if any) or interest on any Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Issuer or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Issuer to pay the principal of (or premium, if any) or interest on any Obligation when and as the same shall become due, whether at Stated Maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Obligation, each Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i) the unpaid amount of such Obligations, (ii) accrued and unpaid interest on such Obligations (but only to the extent not prohibited by law) and (iii) all other monetary Obligations of the Issuer to the Holders and the Trustee.

Each Guarantor agrees that it shall not be entitled to any right of subrogation in respect of any Obligations guaranteed hereby until payment in full in cash of all Obligations. Each Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article Five for the purposes of such Guarantor’s Note Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such Obligations as provided in Article Five, such Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section 1201.

106

Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 1201.

Notwithstanding anything to the contrary contained herein (but subject to the following paragraph), if a Person is required to become a Guarantor pursuant to this Indenture, none of the Issuer or any Subsidiary shall be required to submit any application or filing or otherwise take any action to obtain any authorization or consent of any federal or state Governmental Authority required in order to cause such Person to become a Guarantor (and the requirement to provide such a Guarantee shall be tolled), in each case, to the extent an authorization or consent of such federal or state Governmental Authority is determined by Lumen, Level 3 Parent or the Issuer to be sought in respect of any Material Transaction or any financing relating thereto and has not yet been obtained; provided that (i) such Person is not submitting any application or filing or otherwise taking any action to obtain any authorization or consent of any federal or state Governmental Authority required in order to cause such Person to Guarantee any First Lien Obligation (other than the Securities) and (ii) at the time such federal or state Governmental Authority has approved such Material Transaction, the application, filing or other action to obtain any such authorization or consent of any federal or state Governmental Authority required in order to cause any Person to become a Guarantor shall promptly be made.

Subject in the case of a Regulated Subsidiary to the receipt of such authorizations and consents of federal and state Governmental Authorities as are required in order for such Regulated Subsidiary to guarantee the Securities and pledge Collateral to secure such Guarantee, notwithstanding anything to the contrary herein, no Issuer Restricted Subsidiary shall Guarantee any of the Existing Notes or any First Lien Obligations (other than the Securities), unless such Issuer Restricted Subsidiary (i) is or becomes a Guarantor on the date on which such other Guarantee is Incurred, which Guarantee will be pari passu in right of payment with such Issuer Restricted Subsidiary’s Guarantee of such Existing Notes or First Lien Obligations (other than the Securities) and shall remain in effect for so long as such Issuer Restricted Subsidiary guarantees any Existing Notes or any First Lien Obligation (other than the Securities) and (ii) executes and delivers to the Trustee, substantially concurrently therewith, a supplement or joinder to, and as applicable, an amendment, restatement, supplement or other modification of, the Note Collateral Documents and takes all actions required thereunder to perfect the Liens created thereunder.

SECTION 1202. Contribution. Each of the Issuer and any Guarantor (a “Contributing Party”) agrees that, in the event a payment shall be made by any other Guarantor under any Note Guarantee (the “Claiming Guarantor”), the Contributing Party shall indemnify the Claiming Guarantor in an amount equal to the amount of such payment multiplied by a fraction, the numerator of which shall be the net worth of the Contributing Party on the date hereof and the denominator of which shall be the aggregate net worth of the Issuer and all the Guarantors on the date hereof (or, in the case of any Guarantor becoming a party hereto pursuant to Section 801, the date of the supplemental indenture executed and delivered by such Guarantor).

107

SECTION 1203. Release of Guarantees. The Note Guarantee of a Guarantor that is an Issuer Restricted Subsidiary shall be automatically and unconditionally released (a) in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Issuer or an Issuer Restricted Subsidiary, such that after such transaction, such Guarantor would no longer constitute an Issuer Restricted Subsidiary, and, in each case, such sale, exchange, disposition or other transfer or transaction is made in compliance with all applicable provisions of this Indenture, if any, and such Person is not a guarantor of any First Lien Obligation (other than the Securities), (b) in connection with any sale of all of the Capital Stock of a Guarantor that is an Issuer Restricted Subsidiary to a Person that is not (either before or after giving effect to such transaction) the Issuer or an Issuer Restricted Subsidiary in compliance with all applicable provisions of this Indenture, if any, and such Person is not a guarantor of any First Lien Obligation (other than the Securities), (c) if the Issuer properly designates any Issuer Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary pursuant to Section 914, (d) if such Guarantor is (or immediately after being released from its Guarantee of the Securities will be) released from its Guarantee of all First Lien Obligations except any such release by or as a result of payment of such Guarantee and such Guarantor is not a guarantor under any of the Existing Notes and is not otherwise required to Guarantee the Securities under this Indenture in accordance with Section 1201, (e) if the Issuer exercises the legal defeasance option or covenant defeasance option in accordance with Article Eleven, (f) if such Guarantee was originally Incurred to permit such Guarantor to Incur or guarantee Debt not otherwise permitted pursuant to Section 908, Section 909 or Section 916 and the Debt so Incurred or guaranteed (and any permitted refinancing Debt thereof) has been repaid or discharged (provided that, after giving effect to such release, such Guarantor does not have any outstanding Debt or guarantee that would violate Section 908, Section 909 or Section 916 if such outstanding Debt or guarantee would have been Incurred following the release of such Note Guarantee and such Guarantor is not a guarantor under any First Lien Obligation (other than the Securities)) or (g) upon the occurrence of a Collateral Release Ratings Event.

Upon any occurrence giving rise to a release of a Guarantee as specified above, the Trustee, upon receipt of an Officers’ Certificate from the Issuer and an Opinion of Counsel each stating that all conditions precedent to such release have been satisfied, will execute any documents reasonably required by the Issuer in order to evidence or effect such release, discharge and termination in respect of such Guarantee. None of the Issuer, any Guarantor or the Trustee will be required to make a notation on the Securities to reflect any Guarantee or any such release, termination or discharge.

SECTION 1204. Successors and Assigns. This Article Twelve shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 1205. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article Twelve shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article Twelve at law, in equity, by statute or otherwise.

108

SECTION 1206. Modification. No modification, amendment or waiver of any provision of this Article Twelve, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 1207. Execution of Supplemental Indenture for Future Guarantors. Each Subsidiary which is required to become a Guarantor pursuant to any Section of this Indenture shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit B hereto pursuant to which such Subsidiary shall become a Guarantor under this Article Twelve and shall guarantee the Obligations. Concurrently with the execution and delivery of any such supplemental indenture by Level 3 LLC, Level 3 LLC shall deliver to the Trustee an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized, executed and delivered by Level 3 LLC and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Note Guarantee of Level 3 LLC is a legal, valid and binding obligation of Level 3 LLC, enforceable against Level 3 LLC in accordance with its terms. Each Person then a Guarantor authorizes the Issuer to enter into such a supplemental indenture on its behalf.

SECTION 1208. Limitation on Guarantor Liability. Each Guarantor and, by its acceptance of a Security, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to its Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article Twelve, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

ARTICLE THIRTEEN

COLLATERAL AND SECURITY

SECTION 1301. Collateral.

(a) The due and punctual payment of the Obligations, including payment of the principal of, premium on, if any, and interest on, the Securities when and as the same shall be due and payable, whether on an Interest Payment Date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium on, if any, and

109

interest on the Securities, according to the terms hereunder or thereunder, and all other obligations of the Issuers and the Guarantors to the Holders or the Trustee under the Note Documents are secured as provided in the Note Collateral Documents which the Issuer and the Guarantors have entered into simultaneously with the execution of this Indenture and will be secured as provided by the Note Collateral Documents hereafter delivered as required by this Indenture. The Trustee and the Issuer hereby acknowledge and agree that the Note Collateral Agent has a security interest in the Collateral for the benefit of the Holders, the Trustee and itself, in each case pursuant and subject to the terms of the Note Collateral Documents.

(b) Each Holder, by its acceptance of a Security, (i) consents and agrees to the terms of each Note Collateral Document (including the provisions providing for possession, use, release and foreclosure of Collateral), as originally in effect and as amended, supplemented or replaced from time to time in accordance with its terms or the terms of this Indenture and agrees that it will not contest or support any other person in contesting, in any proceeding (including any insolvency or liquidation proceeding), the perfection, priority, validity or enforceability of a Lien held by or on behalf of any other holder of First Lien Obligations in all or any part of the Collateral, (ii) authorizes the Note Collateral Agent to act on its behalf as “collateral agent” under this Indenture and the Note Collateral Documents, (iii) authorizes the Trustee to appoint the Note Collateral Agent to act on its behalf as the Note Collateral Agent under this Indenture and the Note Collateral Documents, (iv) authorizes and directs the Note Collateral Agent (or any Bailee Collateral Agent) to enter into the Note Collateral Documents to which it is or becomes a party and to perform its obligations and exercise its rights and powers thereunder in accordance therewith, (v) authorizes and empowers the Note Collateral Agent (or any Bailee Collateral Agent) to bind the Holders and other holders of First Lien Obligations as set forth in the Note Collateral Documents to which the Note Collateral Agent (or any Bailee Collateral Agent) is a party and (vi) authorizes the Trustee to authorize the Note Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Note Collateral Agent by the terms of the Note Collateral Documents, including for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any grantor thereunder to secure any of the First Lien Obligations, together with such powers and discretion as are reasonably incidental thereto. Notwithstanding the foregoing, no such consent shall be deemed or construed to represent an amendment or waiver, in whole or in part, of any provision of this Indenture or the Securities. The foregoing will not limit the right of Level 3 Parent, the Issuer or any Restricted Subsidiary to amend, waive or otherwise modify the Note Collateral Documents in accordance with their terms.

(c) Neither the Issuer nor any Guarantor will take or omit to take any action which would materially adversely affect or impair the Liens in favor of the Note Collateral Agent and the holders of the Securities with respect to the Collateral; provided, however, that the foregoing shall not be deemed to prohibit any action or inaction that is otherwise permitted by this Indenture or required by law.

110

SECTION 1302. New Guarantors; After-Acquired Property.

(a) To the extent the Note Collateral Agent’s security interest does not automatically attach to after acquired assets that are intended to be Collateral, promptly (but in any event within 30 days) following the acquisition thereof by the Issuer or any Guarantor, the Issuer or the relevant Guarantor shall notify the Note Collateral Agent thereof and promptly thereafter (but in any event within 90 days after such property’s acquisition) shall cause such assets to be subjected to a Lien securing the Obligations for the benefit of the Note Collateral Agent and shall take, or cause the relevant Guarantor to take, such actions as it determines in good faith to be necessary or as reasonably requested by the Note Collateral Agent to grant and perfect or record such Lien, in each case to the extent contemplated by the Note Collateral Documents, all at the Issuer’s expense; provided that the Collateral in any event shall exclude Excluded Collateral.

(b) Substantially concurrently with any Subsidiary becoming a Guarantor pursuant to Section 1201, the Issuer shall cause all of such Subsidiary’s assets (other than Excluded Collateral) to be subjected to a Lien securing the Obligations for the benefit of the Note Collateral Agent and shall take, or cause such Subsidiary to take, such actions as shall be necessary or reasonably requested by the Note Collateral Agent to grant and perfect or record such Lien, in each case to the extent contemplated by the Note Collateral Documents, all at the Issuer’s expense; provided that the Collateral in any event shall exclude Excluded Collateral.

(c) Subject to the limitations set forth in the Note Collateral Documents, the Existing Issuer Credit Facility and the Existing Issuer Credit Facility Collateral Documents, the Issuer and the Guarantors shall, at their expense, execute, acknowledge, deliver and cause to be duly filed all such further instruments and documents, and take all such actions as the Note Collateral Agent may from time to time reasonably request or as may be necessary or proper to assure, preserve, protect and perfect (and to maintain the perfection of) the security interest and the priority thereof in the Collateral for the benefit of the Holders and the Note Collateral Agent (or any Bailee Collateral Agent) (including the payment of any fees and taxes required in connection with the execution and delivery of the Note Collateral Documents, the granting of such security interests and the filing of any financing statements or other documents in connection therewith), to the extent required by this Indenture and the Note Collateral Documents and to otherwise effectuate the provisions or purposes of this Indenture and the Note Collateral Documents.

(d) Notwithstanding anything to the contrary in this Indenture or the Note Collateral Documents, and for the avoidance of doubt, neither the Issuer nor any Guarantor shall be obligated to grant a security interest in any asset that is not required to also be collateral securing the Existing Issuer Credit Facility or any other First Lien Obligations and, if so required, they shall not be required to perfect any such security interest unless and until they are required to do so in respect of the Existing Issuer Credit Facility or such other First Lien Obligations.

SECTION 1303. Note Collateral Agent.

(a) The Trustee hereby appoints The Bank of New York Mellon Trust Company, N.A. to act on its behalf as the Note Collateral Agent under this Indenture and each of the Note Collateral Documents and to exercise such powers and perform such duties as are expressly delegated to the Note Collateral Agent by the terms of this Indenture and the Note Collateral Documents, and The Bank of New York Mellon Trust Company, N.A. agrees to act as such. The provisions of this Section 1303 are solely for the benefit of the Note Collateral Agent and neither the Trustee nor any of the Holders shall have any rights as a third party beneficiary of any of the provisions contained herein. Each Holder agrees that any action taken by the Note Collateral Agent in accordance with the provisions of this Indenture and the Note Collateral Documents,

111

and the exercise by the Note Collateral Agent of any rights or remedies set forth herein and therein shall be authorized and binding upon all Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture or the Note Collateral Documents, the Note Collateral Agent shall not have any duties or responsibilities except those expressly set forth in this Indenture or in the Note Collateral Documents to which it is party. The Note Collateral Agent shall not be liable for any action taken or not taken by it in the absence of its own gross negligence or willful misconduct. The Note Collateral Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper person. The Note Collateral Agent may also rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper person, and shall not incur any liability for relying thereon. The Note Collateral Agent may consult with legal counsel (who may be counsel for the Trustee), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Without limiting the generality of the foregoing, the Note Collateral Agent:

(i) shall not be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing;

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Note Collateral Documents that the Note Collateral Agent is required to exercise; provided that the Note Collateral Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Note Collateral Agent to liability or that is contrary to any Note Collateral Document or applicable law;

(iii) shall not, except as expressly set forth in the Note Collateral Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Issuer or any of its Affiliates that is communicated to or obtained by the Person serving as the Note Collateral Agent or any of its Affiliates in any capacity;

(iv) shall not be liable for any action taken or not taken by it (A) with the consent or at the request of the Trustee, (B) in the absence of its own gross negligence or willful misconduct or (C) in reliance on a certificate of an authorized officer of the Issuer stating that such action is permitted by the terms of the Intercreditor Agreement. The Note Collateral Agent shall be deemed not to have knowledge of any Event of Default unless and until written notice describing such Event of Default is given to the Note Collateral Agent by the Trustee or the Issuer; and

(v) shall not be responsible for or have any duty to ascertain or inquire into (A) any statement, warranty or representation made in or in connection with any Note Collateral Document, (B) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (C) the performance or observance of any of the covenants, agreements or other terms or conditions set forth therein or the

112

occurrence of any Event of Default, (D) the validity, enforceability, effectiveness or genuineness of any Note Collateral Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Note Collateral Documents, (E) the value or the sufficiency of any Collateral, or (F) the satisfaction of any condition set forth in any Note Collateral Document, other than to confirm receipt of items expressly required to be delivered to the Note Collateral Agent.

By accepting the Securities, each Holder will be deemed to have irrevocably agreed to the foregoing provisions of the prior paragraph and shall be bound by those agreements to the fullest extent permitted by law.

(b) Subject to the provisions of the applicable Note Collateral Document, each Holder, by its acceptance of the Securities, agrees that the Note Collateral Agent shall execute and deliver the Note Collateral Documents to which it is a party and all agreements, power of attorney, documents and instruments incidental thereto, and act in accordance with the terms thereof. The Note Collateral Agent shall hold (directly or through any agent or bailee) and is directed by each Holder to so hold, and shall be entitled to enforce on behalf of the Holders on the Collateral for their benefit, subject to the provisions of the Intercreditor Agreement. Holders may not, individually or collectively, take any direct action to enforce any rights in their favor under the Note Collateral Documents. The Holders may only act by instruction to the Trustee, which shall instruct the Note Collateral Agent.

(c) If at any time or times the Trustee shall receive (i) by payment, foreclosure, setoff or otherwise, any proceeds of Collateral or any payments with respect to the Obligations arising under, or relating to, this Indenture, except for any such proceeds or payments received by the Trustee from the Note Collateral Agent pursuant to the terms of this Indenture, or (ii) payments from the Note Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article Five, the Trustee shall promptly turn the same over to the Note Collateral Agent, in kind, and with such endorsements as may be required to negotiate the same to the Note Collateral Agent such proceeds to be applied by the Note Collateral Agent pursuant to the terms of this Indenture and the Intercreditor Agreement.

(d) The Note Collateral Agent shall have no obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or is owned by any Issuer or Guarantor or is cared for, protected, or insured or has been encumbered, or that the Note Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Issuer’s or any Guarantor’s property constituting Collateral has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Note Collateral Agent pursuant to this Indenture or any Note Collateral Documents, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Note Collateral Agent shall have no other duty or liability whatsoever to the Trustee or any Holder as to any of the foregoing.

113

(e) Notwithstanding anything to the contrary in this Indenture or any Note Collateral Document, neither the Note Collateral Agent nor the Trustee shall be responsible for, and neither makes any representation regarding, the validity, effectiveness or priority of any of the Note Collateral Documents or the security interests or Liens intended to be created thereby.

(f) The benefits, protections and indemnities of the Trustee in Section 607 of this Indenture shall apply mutatis mutandis to the Note Collateral Agent in its capacity as such, including the rights to reimbursement and indemnification.

SECTION 1304. Corporate Note Collateral Agent Required; Eligibility; Conflicting Interests.

(a) There shall be at all times a Note Collateral Agent hereunder which shall have a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of federal, state, territorial or District of Columbia supervising or examining authority, then, for the purposes of this Section 1304, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time a Responsible Officer of the Note Collateral Agent shall have actual knowledge that the Note Collateral Agent ceases to be eligible in accordance with the provisions of this Section 1304, it shall resign immediately in the manner and with the effect hereinafter specified in this Article Thirteen.

(b) The Note Collateral Agent shall be permitted to engage in transactions with Level 3 Parent or its Subsidiaries; provided, however, that if the Note Collateral Agent acquires any conflicting interest, the Note Collateral Agent must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the Commission for permission to continue acting as Note Collateral Agent (and if such permission is not granted within a reasonable time, resign) or (iii) resign.

SECTION 1305. Resignation and Removal; Appointment of Successor.

(a) No resignation or removal of the Note Collateral Agent and no appointment of a successor Note Collateral Agent pursuant to this Article Thirteen shall become effective until the acceptance of appointment by the successor Note Collateral Agent in accordance with the applicable requirements of Section 1306.

(b) The Note Collateral Agent may resign at any time by giving written notice thereof to the Issuer. If the instrument of acceptance by a successor Note Collateral Agent required by Section 1306 shall not have been delivered to the Note Collateral Agent within 30 days after the giving of such notice of resignation, the resigning Note Collateral Agent may petition, at the expense of the Issuer, any court of competent jurisdiction for the appointment of a successor Note Collateral Agent.

(c) The Note Collateral Agent may be removed at any time by Act of the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities, delivered to the Note Collateral Agent and to the Issuer. If the instrument of acceptance by a successor Note Collateral Agent required by Section 1306 shall not have been delivered to the Note Collateral Agent within 30 days after the giving of such notice of removal, the Note Collateral Agent designated for removal may petition, at the expense of the Issuer, any court of competent jurisdiction for the appointment of a successor Note Collateral Agent.

114

(d) If at any time:

(1) the Note Collateral Agent shall cease to be eligible under Section 1304 and shall fail to resign after written request therefor by the Issuer or by any Holder who has been a bona fide Holder of a Security for at least six months, or

(2) the Note Collateral Agent shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Note Collateral Agent or of its property shall be appointed or any public officer shall take charge or control of the Note Collateral Agent or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Issuer, by a Board Resolution (or by a resolution of a duly authorized committee of the Board of Directors of the Issuer), may remove the Note Collateral Agent or (ii) the Holders of at least 10% in aggregate principal amount of the then Outstanding Securities who have been bona fide Holders of a Security for at least six months may, on behalf of themselves and all others similarly situated, petition any court of competent jurisdiction for the removal of the Note Collateral Agent and the appointment of a successor Note Collateral Agent.

(e) If the Note Collateral Agent shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Note Collateral Agent for any cause, the Issuer, by a Board Resolution, shall promptly appoint a successor Note Collateral Agent. If the Issuer does not promptly appoint a successor Note Collateral Agent after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Note Collateral Agent shall be appointed by Act of the Holders of a majority in aggregate principal amount of the Outstanding Securities delivered to the Issuer and the retiring Note Collateral Agent. In either case, the successor Note Collateral Agent so appointed shall, forthwith upon its acceptance of such appointment, become the successor Note Collateral Agent and supersede the successor Note Collateral Agent appointed by the Issuer. If no successor Note Collateral Agent shall have been so appointed by the Issuer or the Holders and accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Note Collateral Agent.

(f) The Issuer shall give notice of each resignation and each removal of the Note Collateral Agent and each appointment of a successor Note Collateral Agent to the Holders of Securities in the manner provided for in Section 106. Each notice shall include the name of the successor Note Collateral Agent and its address for notices hereunder.

Upon request of any such successor Note Collateral Agent, the Issuer shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Note Collateral Agent all such rights, powers and trusts.

No successor Note Collateral Agent shall accept its appointment unless at the time of such acceptance such successor Note Collateral Agent shall be qualified and eligible under this Article Thirteen.

SECTION 1307. Merger, Conversion, Consolidation or Succession to Business.

Any Person into which the Note Collateral Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Note Collateral Agent shall be a party, or any Person succeeding to all or substantially all of the collateral agency business of the Note Collateral Agent, shall be the successor of the Note Collateral Agent hereunder; provided that such Person shall be otherwise qualified and eligible under this Article Thirteen and shall execute and file such documents, including financing statements, or take such other actions as are necessary to maintain the Note Collateral Agent’s perfected security interest in the Collateral.

SECTION 1308. Release of Collateral.

Upon such release, subject to the terms of the Note Collateral Documents all rights in the applicable Collateral securing the Obligations shall revert to the Issuer and the Guarantors.

2.1. Form and Dating

The Original Securities issued on the Issue Date will be offered and sold by the Issuer only to persons reasonably believed to be QIBs and to non-U.S. persons outside the United States in reliance on Regulation S under the Securities Act (“Regulation S”). Such Original Securities may thereafter be transferred to, among others, QIBs and purchasers in reliance on Regulation S. Additional Securities offered after the date hereof may be offered and sold by the Issuer from time to time in accordance with the requirements of the Indenture and applicable law.

(a) Global Securities. Securities initially offered and sold to persons reasonably believed to be QIBs and not pursuant to Regulation S shall be issued initially in the form of one or more permanent global Securities in definitive, fully registered form (collectively, the “Rule 144A Global Security”) and Securities initially offered and sold in reliance on Regulation S shall be issued initially in the form of one or more global securities (collectively, the “Regulation S Global Security”), in each case without interest coupons and with the global securities legend and restricted securities legend set forth in Exhibit 1 hereto, which shall be deposited on behalf of the Holders of the Securities represented thereby with the Securities Custodian, and registered in the name of the Depository or a nominee of the Depository, duly executed by the Issuer and authenticated by the Trustee as provided in the Indenture. The Rule 144A Global Security and Regulation S Global Security are collectively referred to herein as “Global Securities”. The aggregate principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depository or its nominee as hereinafter provided.

(b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Security deposited with or on behalf of the Depository.

The Issuer shall execute and the Trustee shall, in accordance with this Section 2.1(b) and pursuant to an order of the Issuer, authenticate and deliver initially one or more Global Securities that (a) shall be registered in the name of the Depository for such Global Security or Global Securities or the nominee of such Depository and (b) shall be delivered by the Trustee to such Depository or pursuant to such Depository’s instructions or held by the Trustee as Securities Custodian.

Members of, or participants in, the Depository (“Agent Members”) shall have no rights under the Indenture with respect to any Global Security held on their behalf by the Depository or by the Trustee as Securities Custodian or under such Global Security, and the Depository may be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as

APPENDIX A-3

the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any Global Security.

(c) Definitive Securities. Except as provided in Section 2.3, owners of beneficial interests in Global Securities will not be entitled to receive physical delivery of Definitive Securities.

2.2. Transfer and Exchange. (a) Transfer and Exchange of Definitive Securities. When Definitive Securities are presented to the Security Registrar or a co-registrar with a request:

(x) to register the transfer of such Definitive Securities; or

(y) to exchange such Definitive Securities for an equal principal amount of Definitive Securities of other authorized denominations,

the Security Registrar or co-registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Definitive Securities surrendered for transfer or exchange:

(i) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Issuer and the Security Registrar or co-registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and (ii) are being transferred or exchanged pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

(A) if such Definitive Securities are being delivered to the Security Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or

(B) if such Definitive Securities are being transferred to the Issuer, a certification to that effect; or

(C) if such Definitive Securities are being transferred pursuant to an exemption from registration in accordance with Rule 144 under the Securities Act, (i) a certification to that effect and (ii) if the Issuer so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.2(c)(i).

APPENDIX A-4

(b) Transfer and Exchange of Global Securities. (i) The transfer and exchange of Global Securities or beneficial interests therein shall be effected through the Depository, in accordance with the Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Security shall deliver a written order given in accordance with the Depository’s procedures containing information regarding the participant account of the Depository to be credited with a beneficial interest in the Global Security and such account shall be credited in accordance with such instructions with a beneficial interest in the Global Security and the account of the Person making the transfer shall be debited by an amount equal to the beneficial interest in the Global Security being transferred.

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Security to a beneficial interest in another Global Security, the Security Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Security to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Security Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Security from which such interest is being transferred.

(iii) Notwithstanding any other provisions of this Appendix A (other than the provisions set forth in Section 2.3), a Global Security may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

(iv) In the event that a Global Security is exchanged for Definitive Securities pursuant to Section 2.3, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.2 (including the certification requirements set forth on the reverse of the Securities intended to ensure that such transfers comply with Rule 144A, Regulation S or such other applicable exemption from registration under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Issuer.

(i) Except as permitted by the following paragraph (ii), each certificate evidencing the Global Securities and the Definitive Securities (and all Securities issued in exchange therefor or in substitution thereof) shall bear a legend in substantially the following form:

“THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”). THE HOLDER HEREOF, BY PURCHASING THIS NOTE, AGREES FOR THE BENEFIT OF THE ISSUER THAT THIS NOTE MAY NOT BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED (X) PRIOR TO THE FIRST ANNIVERSARY OF THE ISSUANCE HEREOF (OR ANY PREDECESSOR NOTE HERETO) OR (Y) BY ANY HOLDER THAT WAS AN “AFFILIATE” (WITHIN THE

APPENDIX A-5

MEANING OF RULE 144 UNDER THE SECURITIES ACT) OF THE ISSUER AT ANY TIME DURING THE THREE MONTHS PRECEDING THE DATE OF SUCH TRANSFER, IN EITHER CASE OTHER THAN (1) TO THE ISSUER, (2) SO LONG AS THIS NOTE IS ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”), TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE RESALE, PLEDGE OR OTHER TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A (AS INDICATED BY THE BOX CHECKED BY THE TRANSFEROR ON THE CERTIFICATE OF TRANSFER ON THE REVERSE OF THIS NOTE), (3) IN AN OFFSHORE TRANSACTION (AS DEFINED UNDER REGULATION S UNDER THE SECURITIES ACT) IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT (AS INDICATED BY THE BOX CHECKED BY THE TRANSFEROR ON THE CERTIFICATE OF TRANSFER ON THE REVERSE OF THIS NOTE) OR (4) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 (IF APPLICABLE) UNDER THE SECURITIES ACT, IN EACH CASE IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE HOLDER HEREOF, BY PURCHASING THIS NOTE, REPRESENTS AND AGREES FOR THE BENEFIT OF THE ISSUER THAT IT IS (1) A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A OR (2) NOT A U.S. PERSON AND IS OUTSIDE THE UNITED STATES WITHIN THE MEANING OF (OR AN ACCOUNT SATISFYING THE REQUIREMENTS OF PARAGRAPH (k)(2)(i) OF RULE 902 UNDER) REGULATION S UNDER THE SECURITIES ACT.”

Each Definitive Security will also bear the following additional legend:

“IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE SECURITY REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.”

(ii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Security) pursuant to Rule 144 under the Securities Act:

(A) in the case of any Transfer Restricted Security that is a Definitive Security, the Security Registrar shall permit the Holder thereof to exchange such Transfer Restricted Security for a Security that does not bear the legends set forth above and rescind any restriction on the transfer of such Transfer Restricted Security; and

APPENDIX A-6

(B) in the case of any Transfer Restricted Security that is represented by a Global Security, the Security Registrar shall permit the Holder thereof to exchange such Transfer Restricted Security for a Security that does not bear the legends set forth above and rescind any restriction on the transfer of such Transfer Restricted Security,

in either case, if the Holder certifies in writing to the Security Registrar that its request for such exchange was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security).

(d) Cancellation or Adjustment of Global Security. At such time as all beneficial interests in a Global Security have been exchanged for Definitive Securities, redeemed, repurchased or canceled, such Global Security shall be returned by the Depository to the Trustee for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for Definitive Securities, redeemed, repurchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction.

(e) Obligations with Respect to Transfers and Exchanges of Securities.

(i) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Definitive Securities and Global Securities at the Security Registrar’s or co-registrar’s request.

(ii) No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Sections 806 and 1008 of the Indenture).

(iii) The Security Registrar or co-registrar shall not be required to register the transfer of or exchange of any Security for a period beginning 15 days before the mailing of a notice of redemption or an offer to repurchase Securities or 15 days before an Interest Payment Date.

(iv) Prior to the due presentation for registration of transfer of any Security, the Issuer, the Trustee, the Paying Agent, the Security Registrar or any co-registrar may deem and treat the person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Issuer, the Trustee, the Paying Agent, the Security Registrar or any co-registrar shall be affected by notice to the contrary.

APPENDIX A-7

(v) All Securities issued upon any transfer or exchange pursuant to the terms of the Indenture shall evidence the same debt and shall be entitled to the same benefits under the Indenture as the Securities surrendered upon such transfer or exchange.

(f) No Obligation of the Trustee.

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depository or any other Person with respect to the accuracy of the records of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption or repurchase) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be given or made only to the registered Holders (which shall be the Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may conclusively rely and shall be fully protected in relying upon information furnished by the Depository with respect to its members, participants and any beneficial owners.

(ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depository participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of the Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

2.3. Definitive Securities

(a) A Global Security deposited with the Depository or with the Trustee as Securities Custodian pursuant to Section 2.1 shall be transferred to the beneficial owners thereof in the form of Definitive Securities in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such Global Security, only if such transfer complies with Section 2.2 and (i) the Depository notifies the Issuer that it is unwilling or unable to continue as a Depository for such Global Security or if at any time the Depository ceases to be a “clearing agency” registered under the Exchange Act, and a successor Depository is not appointed by the Issuer within 90 days of such notice, or (ii) a Default or an Event of Default has occurred and is continuing or (iii) the Issuer, in its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Securities under the Indenture.

APPENDIX A-8

(b) Any Global Security that is transferable to the beneficial owners thereof pursuant to this Section 2.3 shall be surrendered by the Depository to the Trustee, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations. Definitive Securities issued in exchange for any portion of a Global Security transferred pursuant to this Section shall be executed, authenticated and delivered only in denominations of $2,000 and any integral multiple of $1,000 in excess thereof and registered in such names as the Depository shall direct. Any Definitive Security delivered in exchange for an interest in the Global Security shall, except as otherwise provided by Section 2.2(c), bear the restricted securities legend set forth in Exhibit 1 hereto.

(c) The registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under the Indenture or the Securities.

Method of Payment

The Issuer will pay regular semiannual interest in arrears on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the May 1 or November 1 next preceding the Interest Payment Date even if Securities are canceled after the record date and on or before the Interest Payment Date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Issuer will pay principal and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Issuer will make all payments in respect of a Definitive Security (including principal, premium and interest), by mailing a check to the registered address of each Holder thereof; provided, however, that, at the option of the Issuer, payments on the Securities may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder requests payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

Paying Agent and Security Registrar

Initially, THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., a national banking association (the “Trustee”), will act as Paying Agent and Security Registrar. The Issuer may appoint and change any Paying Agent, Security Registrar or co-registrar without notice.

EXHIBIT 1

to APPENDIX A-6

Indenture

The Issuer issued the Securities under an Indenture dated as of [March 31], 2023 (as amended, modified or supplemented from time to time, the “Indenture”) among the Issuer, Level 3 Parent, the other Guarantors party thereto, the Trustee and the Note Collateral Agent. The terms of the Securities include those stated in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture for a statement of those terms.

The Securities are unsubordinated secured obligations of the Issuer. [This Security is one of the Original Securities referred to in the Indenture issued in an aggregate principal amount of $915,108,000. The Securities include the Original Securities and any Additional Securities]. [This Security is one of the Additional Securities issued in addition to the Original Securities in an aggregate principal amount of $[●] previously issued under the Indenture. The Original Securities and the Additional Securities are treated as a single class of securities under the Indenture.] The Indenture imposes certain limitations on the ability of Level 3 Parent, the Issuer and their respective Restricted Subsidiaries to, among other things, incur Debt, incur Priority Debt and create and incur Liens. The Indenture also imposes limitations on the ability of Level 3 Parent, the Issuer and their respective Restricted Subsidiaries to consolidate or merge with or into any other Person or sell, transfer, assign, lease, convey or otherwise dispose of all or substantially all of the Property of such entities.

To guarantee the due and punctual payment of the principal and interest on the Securities and all other amounts payable by the Issuer under the Indenture and the Securities when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, each of Level 3 Parent and the other Guarantors has fully and unconditionally guaranteed the Securities on an unsubordinated basis pursuant to the terms of the Indenture.

Optional Redemption

At any time or from time to time prior to May 15, 2026, the Issuer may, at its option, redeem some or all of the Securities, upon not less than 10 nor more than 60 days’ prior notice, at a Redemption Price equal to the greater of (1) 100% of the principal amount of the Securities so redeemed and (2) the present value of the Remaining Payments (as defined below) on such Securities being redeemed, discounted to the Redemption Date, on a semi-annual basis, computed using a discount rate equal to the applicable Treasury Rate (as defined below) as of such Redemption Date plus 50 basis points, and, in the case of (1) or (2), accrued and unpaid interest thereon (if any) to, but not including, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date).

“Remaining Payments” means, with respect to any Security that is redeemed, the remaining payments of interest and the payment of principal (or the portion of the principal) that would have been due with regard to that Security after the actual Redemption Date, assuming that the Securities were redeemed on May 15, 2026 at the Redemption Price listed in the table below; provided, however, that, if such Redemption Date is not an Interest Payment Date with respect to such Security, the amount of the next succeeding scheduled interest payment with respect to such Security will be reduced by the amount of interest accrued and unpaid with respect to such Security to such Redemption Date. For the avoidance of doubt, calculations of the Remaining Payments shall not be a duty of the Trustee or any Paying Agent.

EXHIBIT 1

to APPENDIX A-7

“Treasury Rate” means, as of any Redemption Date, the yield to maturity as of such Redemption Date of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 that has become publicly available at least two Business Days prior to such Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the Redemption Date to May 15, 2026; provided, however, that if the period from the Redemption Date to May 15, 2026 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used.

At any time or from time to time on or after May 15, 2026, the Issuer may, at its option, redeem some or all of the Securities, upon not less than 10 nor more than 60 days’ prior notice, at the Redemption Prices set forth below (expressed as percentages of the principal amount thereof), plus accrued and unpaid interest thereon (if any) to, but not including, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), if redeemed during the twelve months beginning May 15 of the years indicated below:


Year	Percentage
2026		105.250	%
2027		102.625	%
2028 and thereafter		100.000	%

In addition, at any time prior to May 15, 2026, the Issuer may, at its option, redeem up to 40% of the original aggregate principal amount of the Securities (including any Additional Securities) at a Redemption Price equal to 110.500% of the principal amount of the Securities so redeemed, plus accrued and unpaid interest thereon (if any) to, but not including, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), with the net cash proceeds from one or more private placements to a Person other than a member of the Lumen Credit Group of, or underwritten public offerings of, Common Stock of Level 3 Parent; provided, however, that at least 60% of the original aggregate principal amount of the Securities (including any Additional Securities) would remain outstanding immediately after giving effect to such redemption. Any such redemption shall be made within 180 days of such private placement or public offering upon not less than 10 nor more than 60 days’ prior notice.

Notwithstanding the foregoing, in connection with any tender offer for the Securities, including any Offer to Purchase, if Holders of not less than 90% in aggregate principal amount of the outstanding Securities validly tender and do not withdraw such Securities in such tender offer and the Issuer, or any third party making such tender offer in lieu of the Issuer, purchases all of the Securities validly tendered and not withdrawn by such Holders, the Issuer or such third party will have the right, upon not less than 10 nor more than 60 days’ prior notice, given not more than 60 days following such Purchase Date, to redeem (with respect to the Issuer) or repurchase (with respect to a third party) all Securities that remain outstanding

EXHIBIT 1

to APPENDIX A-8

following such purchase at a Redemption Price equal to the greater of (i) the highest price offered to any other Holder in such tender offer or other offer to purchase, which may be less than par and shall exclude any early tender premium or similar premium and any accrued and unpaid interest, and (ii) 100% of the principal amount of the Securities redeemed, plus accrued and unpaid interest, if any, thereon, to, but not including, the Redemption Date or Purchase Date, subject to the right of Holders of record of the Securities on the relevant record date to receive interest due on the relevant Interest Payment Date falling on or prior to the Redemption Date or Purchase Date.

Notice of any redemption of, or any offer to purchase, the Securities may, at the Issuer’s discretion, be (i) given in connection with, and prior to the completion of, any private placements or underwritten public offerings of the Issuer’s debt or equity securities, other transactions (or series of related transactions) or an event that constitutes a Change of Control, and (ii) subject to one or more conditions precedent, including but not limited to completion of any such offering, transaction or other event, as the case may be. If any redemption is so subject to the satisfaction of one or more conditions precedent, the notice thereof shall describe each such condition and, if applicable, shall state that, in the Issuer’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and any notice with respect to such redemption or purchase may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the Redemption Date or Purchase Date, or by the Redemption Date or Purchase Date as so delayed, or such notice or offer may be rescinded at any time in the Issuer’s discretion if it reasonably believes that any or all of such conditions will not be satisfied or waived. In addition, the Issuer may provide in such notice or offer that payment of the redemption or purchase price and performance of the Issuer’s obligations with respect to such redemption or offer to purchase may be performed by another person.

If the Issuer chooses to redeem less than all of the Securities, the Trustee will select the particular Securities to be redeemed on a pro rata basis or by lot and, in the case of Securities represented by a Global Security, in accordance with the Depository’s procedures.

If the Issuer has given notice of redemption as provided in the Indenture and made available funds for the redemption of the Securities (or any portion thereof) called for redemption on or prior to the Redemption Date referred to in such notice, those Securities will cease to bear interest on or after that Redemption Date and the only right of the Holders of those Securities will be to receive payment of the Redemption Price, together with any accrued and unpaid interest.

Sinking Fund

The Securities are not subject to any sinking fund.

Notice of Redemption

Notice of redemption will be given in the manner set forth in the Indenture.

EXHIBIT 1

to APPENDIX A-9

Repurchase of Securities at the Option of Holders upon Change of Control Triggering Event

Upon a Change of Control Triggering Event, any Holder of Securities will have the right, subject to certain exceptions and conditions specified in the Indenture, to require the Issuer to repurchase all or any part of the Securities of such Holder at a purchase price in cash equal to 101% of the principal amount of the Securities to be repurchased on the Purchase Date plus accrued and unpaid interest, if any, to such Purchase Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date that is on or prior to the Purchase Date) as provided in, and subject to the terms of, the Indenture.

Denominations; Transfer; Exchange

The Securities are in registered form without coupons in denominations of $2,000 and whole multiples of $1,000 in excess thereof. A Holder may transfer or exchange Securities in accordance with the Indenture. Upon any transfer or exchange, the Security Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Security Registrar need not register the transfer of or exchange of any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or to transfer or exchange any Securities for a period of 15 days prior to the mailing of a notice of redemption of Securities to be redeemed or 15 days before an Interest Payment Date.

10.

Persons Deemed Owners

The registered Holder of this Security may be treated as the owner of it for all purposes.

11.

Unclaimed Money

If money for the payment of principal or interest remains unclaimed for two years, then such money shall be handled in the manner set forth in the Indenture.

12.

Discharge and Defeasance

Subject to certain conditions, the Issuer at any time may terminate some of or all its obligations under the Securities and the Indenture if the Issuer deposits with the Trustee money or Government Securities for the payment of principal and interest on the Securities to redemption or maturity, as the case may be.

13.

Amendment, Waiver

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended without prior notice to any Holder but with the written consent of the Holders of at least a majority (or, with respect to certain covenants, the written consent of at least two-thirds) in aggregate principal amount of the Outstanding Securities and (ii) any default or noncompliance with any provision may be waived with the written consent of the Holders of at

EXHIBIT 1

to APPENDIX A-10

least a majority in principal amount of the Outstanding Securities. Subject to certain exceptions set forth in the Indenture, the Issuer, the Guarantors and the Trustee may, at any time and from time to time, without notice to or consent of any Holders of Securities, amend the Indenture or the Securities: (i) to evidence the succession of another Person to the Issuer, Level 3 Parent or any other Guarantor and the assumption by such successor of the covenants of the Issuer, Level 3 Parent or such other Guarantor, respectively, in the Indenture, in the Securities, in the applicable Note Guarantee and in the applicable Note Collateral Documents, as applicable; (ii) to add to the covenants of Level 3 Parent, the Issuer or any of their respective Subsidiaries, for the benefit of the Holders, or to surrender any right or power conferred upon Level 3 Parent, the Issuer or any other Guarantor by the Indenture; (iii) to add any additional Event of Default; (iv) to provide for uncertificated Securities in addition to or in place of certificated Securities; (v) to evidence and provide for the acceptance of appointment under the Indenture of a successor Trustee or a successor Note Collateral Agent in each case pursuant to the requirements of the Indenture; (vi) to secure the Securities; (vii) to comply with the Trust Indenture Act or the Securities Act (including Regulation S promulgated thereunder); (viii) to add Note Guarantees or to release any Guarantors from Note Guarantees as provided by the terms of the Indenture; (ix) to (a) cure any ambiguity, mistake, omission, defect, inconsistency, or obvious error in the Indenture, or (b) correct or supplement any provision in the Indenture which may be inconsistent with any other provision therein, or to add any other provision with respect to matters or questions arising under the Indenture; provided that, with respect to the foregoing clause (ix)(b), such actions shall not adversely affect the interests of the Holders in any material respect; (x) to conform the Note Documents to any provision of the “Description of New Notes” of the Offering Memorandum to the extent such provision is intended to be a verbatim recitation thereof; or (xi) to add additional assets as Collateral or to release any Collateral from the liens securing the Securities, in each case pursuant to the terms of the Indenture and the Note Collateral Documents, as and when permitted or required by the Indenture or the Note Collateral Documents. The intercreditor provisions of the Note Collateral Documents and any other applicable intercreditor agreement may be amended, waived or otherwise modified from time to time with the consent of the parties thereto. In addition, the Issuer may, without the consent of any other party thereto, amend the Note Collateral Documents and any other applicable intercreditor agreement to designate Debt as “Additional First Lien Obligations”, or as any other Debt subject to the terms and provisions of such agreement.

14.

Defaults and Remedies

If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 30% in aggregate principal amount of the Securities then outstanding, subject to certain limitations, may declare all the Securities to be immediately due and payable. Certain events of bankruptcy or insolvency are Events of Default and shall result in the Securities being immediately due and payable upon the occurrence of such Events of Default without any further act of the Trustee or any Holder.

Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security reasonably satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power under the Indenture.

EXHIBIT 1

to APPENDIX A-11

Before a judgment or decree for payment of the money due has been obtained by the Trustee as provided in the Indenture, the Holders of a majority in aggregate principal amount of the Securities then outstanding, by written notice to the Issuer and the Trustee, may rescind any declaration of acceleration and its consequences if all existing Events of Default have been cured or waived except nonpayment of accelerated principal.

15.

Trustee Dealings with the Issuer

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Issuer or its Affiliates and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee.

16.

No Recourse Against Others

No director, officer, employee, incorporator or stockholder, as such, of the Issuer or any Guarantor shall have any liability for any obligations of the Issuer or any Guarantor under the Securities or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation, solely by reason of its status as a director, officer, employee, incorporator or stockholder of the Issuer or a Guarantor. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

17.

Authentication

This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually, electronically or by facsimile signs the certificate of authentication on the other side of this Security.

WHEREAS the guarantee contained in this Agreement shall constitute a “Loan Proceeds Note Guarantee” for all purposes of the 2030 Notes Indenture, 2027 Notes Indenture, the 2029 Notes Indenture and the Credit Agreement;

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Loan Proceeds Note Guarantor and the Issuer hereby agree as follows:

ARTICLE I

Loan Proceeds Note Guarantee

SECTION 1.01. Guarantees. The Loan Proceeds Note Guarantor hereby irrevocably and unconditionally guarantees to the Issuer and its successors and assigns (a) the full and punctual payment in cash of all obligations of Level 3 LLC in respect of the Loan Proceeds Note, including the payment of principal, premium (if any), interest (including interest arising after the commencement of a bankruptcy or other proceeding, whether or not such a claim is permitted in such proceeding) or any other amount payable thereunder (the “Obligations”). The Loan Proceeds Note Guarantor further agrees that the Obligations may be extended or renewed, in whole or in part, without notice to or further assent from the Loan Proceeds Note Guarantor and that the Loan Proceeds Note Guarantor will remain bound under this Agreement notwithstanding any such extension or renewal of the Obligations.

The Loan Proceeds Note Guarantor waives presentment to, demand of, payment from and protest to Level 3 LLC of any of the Obligations and also waives notice of acceptance of its guarantee and notice of protest for nonpayment. The Loan Proceeds Note Guarantor waives notice of any default under the Obligations. The obligations of the Loan Proceeds Note Guarantor hereunder shall not be affected by (a) the failure of the Issuer to assert any claim or demand or to enforce any right or remedy against Level 3 LLC, any Loan Proceeds Note Guarantor or any other Person under the Loan Proceeds Note or any other agreement or otherwise; (b) any extension or renewal of any obligation thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of the Loan Proceeds Note, any Loan Proceeds Note Guarantee or any other agreement; or (d) the release of any security held by the Issuer for the Obligations, if any.

The Loan Proceeds Note Guarantor further agrees that its guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by the Issuer to any security held for payment of the Obligations.

EXHIBIT C-3

Except as expressly set forth in Section 2.08, the obligations of the Loan Proceeds Note Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of the Loan Proceeds Note Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of the Issuer to assert any claim or demand or to enforce any remedy under the Loan Proceeds Note, any other guarantee of the Loan Proceeds Note or any other agreement, by any waiver or modification of any term thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of the Loan Proceeds Note Guarantor or would otherwise operate as a discharge of the Loan Proceeds Note Guarantor as a matter of law or equity.

The Loan Proceeds Note Guarantor further agrees that its guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or (premium, if any) interest on any Obligation is rescinded or must otherwise be restored by the Issuer upon the bankruptcy or reorganization of Level 3 LLC or otherwise.

In furtherance of the foregoing and not in limitation of any other right which the Issuer has at law or in equity against the Loan Proceeds Note Guarantor by virtue hereof, upon the failure of Level 3 LLC to pay the principal of (or premium, if any) or interest on the Obligations when and as the same shall become due or to perform or comply with any other Obligation, the Loan Proceeds Note Guarantor hereby promises to and will, upon receipt of written demand by the Issuer, forthwith pay, or cause to be paid, in cash, to the Issuer an amount equal to all unpaid amounts in respect of the Obligations.

The Loan Proceeds Note Guarantor agrees that it shall not be entitled to any right of subrogation in respect of any Obligations guaranteed hereby until payment in full in cash of all Obligations.

The Loan Proceeds Note Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Issuer in enforcing any rights under this Article I.

SECTION 1.02. Contribution. The Loan Proceeds Note Guarantor (the “Contributing Party”) agrees that, in the event a payment shall be made by any other guarantor of the Loan Proceeds Note under any other guarantee of the Loan Proceeds Note (the “Claiming Loan Proceeds Note Guarantor”), the Contributing Party shall indemnify the Claiming Loan Proceeds Note Guarantor in an amount equal to the amount of such payment multiplied by a fraction, the numerator of which shall be the net worth of the Contributing Party (which shall be measured on the date hereof) and the denominator of which shall be the aggregate net worth of Level 3 LLC on the Effective Date (as defined in the Credit Agreement) and the guarantors of the Loan Proceeds Note on the respective date of the guarantee of the Loan Proceeds Note executed and delivered by each such guarantor.

EXHIBIT C-4

ARTICLE II

Miscellaneous

SECTION 2.01. Successors and Assigns. This Agreement shall be binding upon the Loan Proceeds Note Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Issuer and, in the event of any transfer or assignment of rights by the Issuer, the rights and privileges conferred upon that party in the Loan Proceeds Note shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of the Credit Agreement.

SECTION 2.02. No Waiver. Neither a failure nor a delay on the part of the Issuer in exercising any right, power or privilege under this Agreement or the Loan Proceeds Note shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Issuer herein and therein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Agreement or the Loan Proceeds Note at law, in equity, by statute or otherwise.

SECTION 2.03. Modification. No modification, amendment or waiver of any provision of this Agreement, nor the consent to any departure by the Loan Proceeds Note Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Issuer, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on the Loan Proceeds Note Guarantor in any case shall entitle the Loan Proceeds Note Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 2.04. [Reserved]

SECTION 2.05. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.
