Section 1.03. 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.

60

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.

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 1.04. 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 6.01) 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

61

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 1.05. 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,

(a) 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

(b) the 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 Collateral Agent c/o the Trustee as described in clause (a) above, or

(c) 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), 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,

62

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 without limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse by third parties.

Section 1.06. Notice to Holders; Waiver. Where this Indenture provides for notice or communication of any event to Holders by the Issuer or the Trustee, such notice shall be given (unless otherwise herein expressly provided) either (i) 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 or (ii) in the case of Securities held through the Depository, to Depository participants via the Depository’s electronic messaging system, 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 or electronic delivery, neither the failure to electronically deliver or mail such notice, nor any defect in any notice so mailed or electronically delivered, 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 1.07. 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 1.08. Successors and Assign s. 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 1.10. 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.

63

Notwithstanding any other provision of this Indenture, if a court of competent jurisdiction – in a final and unstayed order – determines that any aspect of the Level 3 Senior Unsecured Notes Transaction (as defined in the Transaction Support Agreement) is invalid for any reason, such determination shall not (directly or indirectly) constitute a default or breach of this Indenture or any other Note Document.

Section 1.11. 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 1.12. 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 1.13. Trust Indenture Act. For the avoidance of doubt, the Trust Indenture Act is not applicable to this Indenture.

Section 1.14. 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 1.15. 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 1.16. 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 1.17. Exhibits. All exhibits attached hereto are by this reference made a part hereof with the same effect as if herein set forth in full.

64

Section 1.18. 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 1.19. Duplicate Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

Section 1.20. Waiver of Jury Trial. EACH OF LEVEL 3 PARENT, EACH HOLDER BY ACCEPTANCE OF THE SECURITIES, THE ISSUER, THE TRUSTEE AND THE 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 1.21. Force Majeure. In no event shall the Trustee or Collateral Agent 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, without limitation, any act or provision of any present or future law or regulation or governmental authority, strikes, riots, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, sabotage, 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 or the unavailability of the Federal Reserve Bank wire or telex or other wire or communication facility; 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 1.22. 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 1.23. Submission to Jurisdiction. The parties and each Holder (by acceptance of the Securities) 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.

65

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

(b) the issue price, the issue date and the CUSIP number of such Additional Securities;

(c) 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, the Issuer shall lend to Level 3 Communications 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; provided that such calculation or the correctness of the amount of the Loan Proceeds Note or any increase in the amount thereof shall not be a duty or obligation of the Trustee.

67

Section 3.02. 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 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 3.03. Security Registrar and Paying Agent. The Issuer shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Security Registrar”) and an office or agency in the United States 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 9.02 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 6.07.

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

Section 3.04. 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

68

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 3.05. 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 3.06. 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 to protect the Issuer and in the judgement of the Trustee to protect 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 3.07. 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 3.08. 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. The Issuer may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancellation.

Section 3.09. Defaulted Amounts. 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 at the rate provided in Section 9.01 hereof. The Issuer may pay the defaulted interest to the persons who are Holders on a subsequent special record date. The Issuer shall notify the Trustee of any defaulted interest payment and fix or cause to be fixed any such special record date for the payment to the reasonable satisfaction of the Trustee and shall deliver to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

69

Section 3.10. 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 4

SATISFACTION AND DISCHARGE

Section 4.01. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect (subject to Section 11.06 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

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

(A) have become due and payable, or

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

(C) are to be called for redemption within one year under irrevocable arrangements satisfactory to the Trustee in its reasonable 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 (A), (B) or (C) above, has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness 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;

70

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

(c) 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 6.07 and 6.09 and, if money shall have been deposited with the Trustee pursuant to clause (a)(ii) of this Section 4.01, the obligations of the Trustee under Section 4.02 and the last paragraph of Section 9.03 shall survive such satisfaction and discharge.

Section 4.02. Application of Trust Money. Subject to the provisions of the last paragraph of Section 9.03, all money deposited with the Trustee pursuant to Section 4.01 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 5

REMEDIES

Section 5.01. 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):

(a) failure to pay principal of (or premium, if any, on) any Security when due; or

71

(f) any event or condition occurs that results in any Material Indebtedness becoming due prior to its scheduled maturity or failing to be paid at its scheduled maturity; provided, that this clause (f) shall not apply to any secured Indebtedness that becomes due as a result of the voluntary sale or transfer of the property or assets securing such Indebtedness if (x) such sale or transfer is permitted hereunder and under the documents providing for such Indebtedness and (y) repayments are made as required by the terms of the respective Indebtedness; or

(g) the failure by Level 3 Parent, the Issuer or any Significant Subsidiary to pay one or more final judgments aggregating in excess of $75,000,000, which judgments are not discharged or effectively waived or stayed for a period of 45 consecutive days, or any action shall be legally taken by a judgment creditor to attach or levy upon assets or properties of Level 3 Parent, the Issuer or any Significant Subsidiary to enforce any such judgment; or

(h) any Note Guarantee of Level 3 Parent, Level 3 Communications or any other Guarantor that is a Significant Subsidiary, 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 Communications or any other Guarantor that is a Significant Subsidiary denies or disaffirms in writing its obligations under its Note Guarantee; or

(i) an involuntary proceeding shall be commenced or an involuntary petition shall be filed in a court of competent jurisdiction seeking (i) relief in respect of Level 3 Parent, the Issuer or any of the Significant Subsidiaries, or of a substantial part of the property or assets of Level 3 Parent, the Issuer or any Significant Subsidiary, under the Bankruptcy Code, or any other federal, state or foreign bankruptcy, insolvency, receivership or any other Debtor Relief Law, (ii) the appointment of a receiver, trustee, custodian, sequestrator, conservator, examiner, liquidator or similar official for Level 3 Parent, the Issuer or any of the Significant Subsidiaries or for a substantial part of the property or assets of Level 3 Parent, the Issuer or any of the Significant Subsidiaries or (iii) the winding-up, liquidation, reorganization, dissolution, compromise, arrangement or other relief of Level 3 Parent, the Issuer or any Significant Subsidiary (except in a transaction permitted hereunder); and such proceeding or petition shall continue undismissed for 60 days or an order or decree approving or ordering any of the foregoing shall be entered; or

(j) Level 3 Parent, the Issuer or any Significant Subsidiary shall (i) voluntarily commence any proceeding or file any petition seeking relief under the Bankruptcy Code, as now constituted or hereafter amended, or any other federal, state or foreign bankruptcy, insolvency, receivership or any other Debtor Relief Law, (ii) consent to the institution of, or fail to contest in a timely and appropriate manner, any proceeding or the filing of any petition described in clause (i) above, (iii) apply for or consent to the appointment of a receiver, trustee, custodian, sequestrator, conservator, examiner, liquidator or similar official for Level 3 Parent, the Issuer or any of the Significant Subsidiaries or for a substantial part of the property or assets of Level 3 Parent, the Issuer or any Significant Subsidiary, (iv) file an answer admitting the material allegations of a petition filed against it in any such proceeding, (v) make a general assignment for the benefit of creditors or (vi) become unable or fail generally to pay its debts as they become due; or

72

(k) any security interest purported to be created by any Collateral Document and to extend to assets that constitute a material portion of the Collateral shall cease to be, or shall be asserted in writing by the Issuer or any Guarantor not to be, a valid and perfected security interest (perfected as or having the priority required by this Indenture or the relevant Collateral Document and subject to such limitations and restrictions as are set forth herein and therein) in the securities, assets or properties covered thereby, except to the extent that any such loss of perfection or priority results from the limitations of foreign laws, rules and regulations as they apply to pledges of Equity Interests in Foreign Subsidiaries or the application thereof, or from failure of the Collateral Agent (or any agent acting as gratuitous bailee thereof) to maintain possession of certificates actually delivered to it representing securities pledged under the Collateral Agreement (so long as such failure does not result from the breach or non-compliance with the Note Documents by the Issuer or any Guarantor).

Any notice of default, notice of acceleration or instruction to the Trustee to provide a notice of default, notice of acceleration or take any other action (a “Noteholder Direction”) provided by any one or more holders of the Securities (each a “Directing Holder”) shall be accompanied by a written representation from each such holder delivered to the Issuer and the Trustee that such holder is not (or, in the case such holder is the Depository or its nominee, that such holder is being instructed solely by beneficial owners that have represented to such holder that they are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction relating to the delivery of a notice of default shall be deemed a continuing representation until the resulting Event of Default is cured or otherwise ceases to exist or the Securities are accelerated. In addition, each Directing Holder shall be deemed, at the time of providing a Noteholder Direction, to covenant to provide the Issuer with such other information as the Issuer may reasonably request from time to time in order to verify the accuracy of such noteholder’s Position Representation within five (5) Business Days of request therefor (a “Verification Covenant”). In any case in which the holder is the Depository or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the Securities in lieu of the Depository or its nominee and the Depository shall be entitled to conclusively rely on such Position Representation and Verification Covenant in delivering its direction to the Trustee. In no event shall the Trustee have any liability or obligation to ascertain, monitor or inquire as to whether any holder is Net Short and/or whether such holder has delivered any Position Representation, Verification Covenant, Noteholder Direction, or any related certifications under this Indenture or in connection with the Securities or if any such Position Representation, Verification Covenant, Noteholder Direction, or any related certifications comply with this Indenture, the Securities, or any other document. It is understood and agreed that the Issuer and the Trustee shall be entitled to conclusively rely on each representation, deemed representation and certification made by, and covenant of, each beneficial owner provided for in this paragraph. Notwithstanding any other provision of this Indenture, the Securities or any other document, the provisions of this paragraph shall apply and survive with respect to each beneficial owner notwithstanding that any such person may have ceased to be a beneficial owner, this Indenture may have been terminated or the Securities may have been redeemed in full.

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 initiated litigation in a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in

73

breach of its Position Representation, and seeking to invalidate any default, Event of Default or acceleration (or notice thereof) that resulted from the applicable Noteholder Direction, the cure period with respect to such default shall be automatically stayed and the cure period with respect to such default or Event of Default shall be automatically reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter 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. 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 or Event of Default shall be automatically stayed and the cure period with respect to any default or Event of Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy 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 (other than any indemnity such Directing Holder may have offered the Trustee), with the effect that such default or Event of Default shall be deemed never to have occurred, acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice of such default or Event of Default.

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 as the result of a bankruptcy or similar proceeding shall not require compliance with the foregoing paragraphs (except for any rights or protections of the Trustee).

For the avoidance of doubt, the Trustee shall be entitled to conclusively rely on any Noteholder Direction, Position Representation, Verification Covenant or Officers’ Certificate delivered to it in accordance with this Indenture, shall have no duty to inquire as to or investigate the accuracy of any Position Representation, Noteholder Direction, Verification Covenant or Officers’ Certificate, enforce compliance with any Verification Covenant, verify any statements in any Officers’ Certificate, Position Representation, Noteholder Director or Verification Covenant 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. The Trustee shall have no liability to the Issuer, any holder or any other person in connection with any Noteholder Direction (or items delivered in connection with any Noteholder Direction) or to determine whether or not any holder has delivered any Position Representation, Verification Covenant, Noteholder Direction, or any related certification or that such Position Representation, Verification Covenant, Noteholder Direction, or any related certification is accurate or conforms with this Indenture or any other agreement.

The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

74

Section 5.02. Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Section 5.01(i) or 5.01(j) 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, further, that a notice of default may not be given with respect to any action taken, and reported publicly or to holders and the Trustee, more than two years prior to such notice of default. 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 5, 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:

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

(i) all overdue interest on all Outstanding Securities,

(ii) 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,

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

(iv) 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

(b) 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 5.13.

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

Section 5.03. 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.

75

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 5.04. 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,

(a) 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 or Collateral Agent and their respective agents and counsel) and of the Holders allowed in such judicial proceeding, and

(b) 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 or Collateral Agent and their respective agents and counsel, and any other amounts due the Trustee or Collateral Agent hereunder.

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.

76

Section 5.05. 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 5.06. Application of Money Collected. Subject to the terms of the First Lien/First Lien Intercreditor Agreement and the Collateral Agreement, any money collected by the Trustee pursuant to this Article 5 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 (acting in any capacity hereunder) and/or the Collateral Agent (acting in any capacity hereunder);

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 5.07. 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

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

(b) the Holders of not less than 30% in aggregate principal amount of the Outstanding Securities shall have made written request and offered indemnity satisfactory to the Trustee in its sole discretion to institute such proceeding and the Trustee shall have failed to institute such proceeding within 60 days; and

(c) 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;

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.

77

Section 5.08. Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, including Section 5.07, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment as provided herein (including, if applicable, Article 11) 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 5.09. 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 5.10. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee, Collateral Agent 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 5.11. Delay or Omission Not Waiver. Except as otherwise provided in the proviso of the first paragraph of Section 5.02, 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 5 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 5.12. 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

(a) such direction shall not be in conflict with any rule of law or with this Indenture, any Intercreditor Agreement or the Collateral Agreement,

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

78

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

Section 5.13. 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

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

(b) in respect of a covenant or provision hereof which under Article 8 cannot be modified or amended without the consent of the Holder of each Outstanding Security affected, or

(c) in respect of the covenant contained in Section 9.15, which under Article 8 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 Holders of a majority in principal amount of the Outstanding Securities have consented to such waiver and attaching such consents upon which, subject to Section 1.04, 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 5.14. 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 5.15. 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 5.15 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.

(i) the Trustee undertakes to perform such duties and only such duties as are specifically and expressly set forth in this Indenture and the Trustee shall not be liable except for the performance of such duties, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) 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 of which a Responsible Officer of the Trustee has actual knowledge, 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.

The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder. The Trustee shall not be accountable for the use or application by the Issuer of Securities or the proceeds thereof.

Section 6.05. May Hold Securities.

However, the Trustee must comply with Section 6.08.

Section 6.06. 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.

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

(b) except as otherwise expressly provided herein, to reimburse the Trustee or Collateral Agent upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee or Collateral Agent in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of their respective agents and counsel for each), except any such expense, disbursement or advance as shall be determined to have been caused by the Trustee or Collateral Agent’s own gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final, non-appealable order); and

83

The obligations of the Issuer hereunder to compensate the Trustee and Collateral Agent, to pay or reimburse the Trustee and Collateral Agent for expenses, disbursements and advances and to indemnify and hold harmless the Trustee and Collateral Agent shall constitute additional indebtedness hereunder.

Section 6.08. 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 6.08, 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 6.08, it shall resign immediately in the manner and with the effect hereinafter specified in this Article 6.

(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 6.10 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.

84

(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 6.10 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:

(i) the Trustee shall cease to be eligible under Section 6.08 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

(ii) 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 1.06. 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 6.10. 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

85

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 6.

Section 6.11. 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 6, 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.

It shall not be necessary for any Act of Holders under this Section 8.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

Section 8.03. Execution of Supplemental Indentures. In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article 8 or the modifications thereby of the trusts created by this Indenture, the Trustee shall receive, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate stating that the execution of such supplemental indenture is authorized or permitted by this Indenture and that all conditions precedent to the execution of such supplemental indenture have been fulfilled.

94

The Trustee may, but shall not be obligated to, enter into any supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

Section 8.04. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article 8, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

Section 8.05. Reference in Securities to Supplemental Indentures. Securities authenticated and delivered after the execution of any supplemental indenture pursuant to this Article 8 may bear a notation in form approved by the Trustee and the Issuer as to any matter provided for in such supplemental indenture.

Section 8.06. Notice of Supplemental Indentures. Promptly after the execution by the Issuer, the Guarantors and the Trustee of any supplemental indenture pursuant to this Article 8, the Issuer shall give notice thereof to the Holders of each Outstanding Security affected, in the manner provided for in Section 1.06, setting forth in general terms the substance of such supplemental indenture.

ARTICLE 9

COVENANTS

Section 9.01. 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. An installment of principal of or interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds as of 11:00 A.M. New York City time money sufficient to pay all principal and interest then due and the Trustee or Paying Agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture.

The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Code) (and premium, if any) on overdue principal at the rate equal to 2.0% per annum in excess of the then applicable interest rate on the Securities to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Code) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful.

Section 9.02. Maintenance of Office or Agency. The Issuer shall maintain in the United States 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, which shall not constitute service of process. An office of the Trustee, Wilmington Trust,

95

National Association at 1100 North Market Street, Wilmington, Delaware 19890, 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 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 United States 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 9.03. 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 9.03, that such Paying Agent shall:

(a) 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;

(b) 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;

(c) 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

(d) 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.

96

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.

Subject to any abandoned property law, 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 9.04. Existence. Subject to Article 7, 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 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 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 9.05. 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 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, (a) such reports shall not be required to comply with any segment reporting requirements (whether pursuant to generally accepted accounting principles or Regulation S-X) in greater detail than is customarily provided in an offering memorandum prepared in connection with a Rule 144A offering, (b) such reports shall not be required to present beneficial ownership information and (c) such reports shall not be required to provide

97

guarantor/non-guarantor financial data. Reports relating to delivery of annual financial statements shall be provided within 120 days after the end of each fiscal year, and reports relating to interim quarterly financial statements shall be provided within 60 days after the end of each of the first three fiscal quarters of each fiscal year. 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 by posting such information on a password-protected website (which may be non-public, require a confidentiality acknowledgment and be maintained by Level 3 Parent or its designee) to which access will be given to (i) any Holder of the Securities, (ii) to any beneficial owner of the Securities, who provides its e-mail address to Level 3 Parent or its designee and certifies that it is a beneficial owner of Securities, (iii) to any prospective investor who provides its e-mail address to Level 3 Parent or its designee and certifies that it is a QIB, or (iv) 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. 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 review such financial information (which, for the avoidance of doubt, access may be limited to those who have access to the password-protected website and have provided a confidentiality acknowledgement). The conference call will not be later than five 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) 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 9.05 with respect to financial information relating to Level 3 Parent by furnishing financial information relating to such parent; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such parent and any of its Subsidiaries other than Level 3 Parent and its Subsidiaries, on the one hand, and the information relating to Level 3 Parent and its Subsidiaries, on the other hand.

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.

98

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). The Trustee shall have no liability or responsibility for the filing, timeliness or content of such reports.

Section 9.06. 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 9.05 commencing with the annual report for the fiscal year ended December 31, 2024, 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 9.06(a), such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

(b) When (to the knowledge of the Issuer or any Subsidiary) any Default has occurred and is continuing under this Indenture, or if the trustee for or the holder of any other evidence of Indebtedness of the Issuer or any Subsidiary gives any notice or takes any other action with respect to a claimed default (other than with respect to Indebtedness 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 electronically, 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 9.07. 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 $1.00, in accordance with the procedures set forth in this Section 9.07 and this Indenture.

(b) Within 30 days following the occurrence of both a Change of Control and a Rating Decline with respect to the Securities within 30 days of each other (a “Change of Control Triggering Event”), the Issuer will be required to make an Offer to Purchase all Outstanding Securities 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 excluding, 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).

(c) The Issuer, the Trustee and/or any designated Paying Agent shall perform their respective obligations for the Offer to Purchase as specified in the Offer or as required hereunder. 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 applicable Paying Agent (or, if the Issuer is acting as its own Paying Agent, segregate and hold in trust as provided in Section 9.03) money sufficient to pay the Purchase Price of all Securities or portions

99

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 applicable 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 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 applicable Paying Agent, the Paying Agent, 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 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), but excluding Lumen or any Wholly-Owned Subsidiary of Lumen, 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 of the assets of Level 3 Parent and its Subsidiaries considered as a whole 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, (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 and (ii) 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 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.

100

(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 9.07 by virtue thereof.

(g) Notwithstanding anything to the contrary herein, so long as (i) any of the Other 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 Other Notes or (ii) if any loans or commitments are outstanding under the Credit Agreements, if a Change of Control Triggering Event (as defined in each Credit Agreement, to the extent applicable) has occurred, a Change of Control Triggering Event with respect to the Securities shall also be deemed to have occurred.

Section 9.08. Limitation on Indebtedness. (a) The Issuer and Level 3 Parent will not, and will not permit any Subsidiary to, directly or indirectly, Incur any Indebtedness; provided, however, that (i) Permitted Consolidated Cash Flow Debt may be Incurred in an aggregate principal amount not to exceed 5.75 times Pro Forma LTM EBITDA; provided, that, if the Issuer’s long-term secured debt rating is at the time rated either “B2” or less from Moody’s or “B” or less from S&P, then Permitted Consolidated Cash Flow Debt shall not exceed an aggregate principal amount of 5.00 times Pro Forma LTM EBITDA and (ii) any Permitted Refinancing Indebtedness in respect thereof may be Incurred.

107

(c) at the option of the Issuer, any Indebtedness and/or Lien incurred to finance a Limited Condition Transaction shall be deemed to have been incurred on the date of execution of the acquisition agreement, the declaration of the dividend by the Board of Directors of the Issuer or the applicable Subsidiary or the giving of the irrevocable notice of repayment or redemption, as applicable, related to such Limited Condition Transaction (and not at the time such Limited Condition Transaction is consummated) and the First Lien Leverage Ratio, Total Leverage Ratio, Priority Leverage Ratio and/or compliance with Pro Forma LTM EBITDA in respect of Permitted Consolidated Cash Flow Debt shall be tested (x) in connection with such incurrence, as of the date of execution of the acquisition agreement, the declaration of the dividend by the Board of Directors of the Issuer or the applicable Subsidiary or the giving of the irrevocable notice of repayment or redemption, as applicable related to such Limited Condition Transaction was entered into, giving pro forma effect to such Limited Condition Transaction, to any such Indebtedness or Lien, and to all transactions in connection therewith and (y) in connection with any other incurrence after the date definitive acquisition agreement was entered into, the date of declaration of the dividend by the Board of Directors of the Issuer or the applicable Subsidiary or the date of giving of the irrevocable notice of repayment or redemption, as applicable related to such Limited Condition Transaction and prior to the earlier of the consummation of such Limited Condition Transaction or the termination of such definitive agreement or abandonment of such dividend, repayment or redemption prior to the incurrence, both (i) on the basis set forth in clause (x) above and (ii) without giving effect to such Limited Condition Transaction or the incurrence of any such Indebtedness or Liens or the other transactions in connection therewith.

This Indenture does not treat (x) unsecured Indebtedness as subordinated or junior in right of payment to secured Indebtedness merely because it is unsecured or (y) senior Indebtedness as subordinated or junior in right of payment to any other senior Indebtedness merely because it has a junior priority with respect to the same collateral.

Accrual of interest, accrual of dividends, the accretion of accreted value, the accretion or amortization of original issue discount, the payment of interest in the form of additional Indebtedness, the payment of dividends in the form of additional shares of Disqualified Stock or the reclassification of commitments or obligations not treated as Indebtedness due to a change in GAAP will not be deemed to be an incurrence of Indebtedness for purposes of this Section 9.08 (or, for the avoidance of doubt, the incurrence of a Lien for purposes of Section 9.10).

For the avoidance of doubt, Permitted Refinancing Indebtedness (and all subsequent refinancings thereof with Permitted Refinancing Indebtedness) shall not increase the amount of Indebtedness that is permitted to be incurred pursuant to any provision of this Section 9.08 other than, in each case, as permitted by the definitions of Permitted Refinancing Indebtedness with respect to each such incurrence of Permitted Refinancing Indebtedness.

(b) If the Issuer or any Guarantor (or any entity required to become a Guarantor pursuant to this Indenture) creates (i) any Lien (including without limitation any additional Lien) upon any property or assets to secure any First Lien Obligation or (ii) any Junior Lien upon any property or assets to secure any Junior Lien Obligation, in each case that is not a Permitted Lien, 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 Agreements. If the foregoing obligation to grant a Lien on any property or assets to secure the Securities or a Note Guarantee

114

arises due to the grant of a Lien on such property or assets to secure the Credit Agreement 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 12.03. 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 Credit Agreement Obligations (or the obligations under any Replacement Credit Facility) or Junior Lien Obligations, 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 the 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 9.10 if, on the applicable date, Level 3 Parent and each Subsidiary that has granted any Lien on any property or assets to secure the Credit Agreement 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 Credit Agreement, Level 3 Parent, the Issuer and any applicable 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 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 9.10 with respect to any Lien attaching to property or assets subsequent to such date. For purposes of this paragraph (c), the requirement that Level 3 Parent, the Issuer or any 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 Subsidiary as necessary to enable them to comply with their obligations under this paragraph (c).

(d) For purposes of determining compliance with this Section 9.10, (x) a Lien securing an item of Indebtedness need not be permitted solely by reference to one category of permitted Liens (or any portion thereof) described in Section 9.10(a)(i) through (xli) but may be permitted in part under any combination thereof and (y) in the event that a Lien securing an item of Indebtedness (or any portion thereof) meets the criteria of one or more of the categories of permitted Liens (or any portion thereof) described in Section 9.10(a)(i) through (xli), the Issuer

115

may, in its sole discretion, classify or divide such Lien securing such item of Indebtedness (or any portion thereof) in any manner that complies with this Section 9.10 (including, in the case of Lien incurred on the same day, electing the order in which such Lien shall be deemed incurred for purposes of computing the available amount under any category) and will be entitled to only include the amount and type of such Lien or such item of Indebtedness secured by such Lien (or any portion thereof) in one of the above clauses and such Lien securing such item of Indebtedness (or portion thereof) will be treated as being incurred or existing pursuant to only such clause or clauses (or any portion thereof).

Section 9.11. Limitation on Restricted Payments.

(a) The Issuer shall not, and shall not permit any of the Subsidiaries to, directly or indirectly:

(i) declare or pay any dividend or make any other distribution (by reduction of capital or otherwise), whether in cash, property, securities or a combination thereof, with respect to any of its Equity Interests (other than dividends and distributions on Equity Interests payable solely by the issuance of Qualified Equity Interests of the person declaring, paying or making such dividends or distributions);

116

during such calendar year from sales of Qualified Equity Interests of the Issuer to directors, consultants, officers or employees of the Issuer or any Subsidiary in connection with permitted employee compensation and incentive arrangements and (y) the amount of net proceeds of any key-man life insurance policies received during such calendar year, which, if not used in any year, may be carried forward to any subsequent calendar year); provided, further, that cancellation of Indebtedness owing to the Issuer or any Subsidiary from members of management of the Issuer or its Subsidiaries in connection with a repurchase of Equity Interests of the Issuer will not be deemed to constitute a Restricted Payment for purposes of this Section 9.11;

(vi) Restricted Payments may be made to make payments, in cash, in lieu of the issuance of fractional shares, upon the exercise of warrants or upon the conversion or exchange of Equity Interests of any such person;

117

(ix) to the extent constituting a Restricted Payment, any disposition of (i) Securitization Assets made in connection with a Qualified Securitization Facility permitted under Section 9.08(b)(xxvii), (ii) Receivables made in connection with any Qualified Receivable Facility permitted under Section 9.08(b)(xxviii) and (iii) Digital Products made in connection with any Qualified Digital Products Facility permitted under Section 9.08(b)(xxx);

(x) Restricted Payments of Specified Digital Products or Specified Digital Products Investments;

(xi) Restricted Payments in an aggregate amount not to exceed $335,000,000; and

For purposes of determining compliance with this Section 9.11, (A) a Restricted Payment or Permitted Investment need not be permitted solely by reference to one category of permitted Restricted Payments or Permitted Investment (or any portion thereof) but may be permitted in part under any relevant combination thereof and (B) in the event that a Restricted Payment or Permitted Investment (or any portion thereof) meets the criteria of one or more of the categories of permitted Restricted Payments or Permitted Investments (or any portion thereof), the Issuer may, in its sole discretion, classify or divide such Restricted Payment or Permitted Investment (or any portion thereof) in any manner that complies with this Section 9.11 and will be entitled to only include the amount and type of such Restricted Payment or Permitted Investment (or any portion thereof) in one or more (as relevant) of the applicable clauses (or any portion thereof) and such Restricted Payment or Permitted Investment (or any portion thereof) shall be treated as having been made or existing pursuant to only such clause or clauses (or any portion thereof).

118

The amount of any Restricted Payment (excluding any Restricted Investment, the value of which shall be determined in accordance with the definition of “Investments”) made other than in the form of cash, Cash Equivalents or other cash equivalents shall be the Fair Market Value thereof valued at the time of the making thereof, and without giving effect to any subsequent write-downs or write-offs thereof.

(c) Notwithstanding anything herein to the contrary, the foregoing provisions of Section 9.11 will not prohibit the payment of any Restricted Payment or the making of Permitted Investment constituting a Limited Condition Transaction if such transaction would have complied with the provisions of this Section 9.11 on the date of the declaration of the dividend by the Board of Directors of the Issuer or the applicable Subsidiary or the date of giving of the applicable notice of prepayment or redemption, in each case, constituting a Limited Condition Transaction (it being understood that such Restricted Payment or Permitted Investment shall be deemed to have been made on the date of declaration or notice for purposes of such provision).

Section 9.12. Limitation on Asset Sales. (a) The Issuer shall not, and shall not permit any Subsidiary to, make any Asset Sale unless:

(x) no Event of Default under Section 5.01(a), 5.01(b), 5.01(i) or 5.01(j) shall have occurred and be continuing at the time of such disposition or would result therefrom,

(y) such Asset Sale is for Fair Market Value and

(z) at least 75% of the consideration proceeds of such Asset Sale consist of cash or Cash Equivalents;

provided, that for purposes of this clause (z), each of the following shall be deemed to be cash:

(ii) any notes or other obligations or other securities or assets received by the Issuer or such Subsidiary from the transferee that are converted by the Issuer or such Subsidiary into cash within 180 days after receipt thereof (to the extent of the cash received).

(b) [Reserved].

(c) The amount of any Net Proceeds shall constitute “Excess Proceeds”. If there are any Excess Proceeds, the Issuer (x) shall make an offer to all holders of the Securities to purchase the maximum principal amount of the Securities (an “Asset Sale Offer”) that is at least $1.00 and an integral multiple of $1.00 in excess thereof and (y) at the option of the Issuer, may prepay Other First Lien Debt (or make an offer to holders of any Other First Lien Debt) to the extent any such prepayment is required thereby, on a pro rata basis (subject to adjustments to maintain the authorized denominations for the Securities) among the Securities and such Other First Lien Debt based on the principal amount thereof, in each case that may be purchased or

119

prepaid out of the Excess Proceeds at an offer or prepayment price, as applicable, in cash in an amount equal to 100% of the principal amount thereof (or, in the event the Securities or Other First Lien Debt were issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest, to, but excluding, the date fixed for the closing of such offer or prepayment; provided, that Net Proceeds of the kind described in clauses (d), (e), (f) and (g) of the definition thereof that are required to be subject to an Asset Sale Offer shall be reduced dollar-for-dollar by the amount of Net Proceeds applied to prepay, repurchase, redeem or otherwise discharge the Second Lien Notes and other Indebtedness for borrowed money secured by a Junior Lien in accordance with the following proviso; provided, further, that if the Issuer shall deliver a certificate of a Responsible Officer of the Issuer to the Trustee promptly following receipt of any such Net Proceeds setting forth the Issuer’s intention to apply an amount equal to all or any portion of such Net Proceeds to prepay, repurchase, redeem or otherwise discharge the Second Lien Notes or other Indebtedness for borrowed money secured by a Junior Lien, then the Issuer shall have 90 days to apply such amount in such manner; provided, however, that if all or a portion of such amount is not so applied by such 90th day or is no longer intended to be or cannot be so applied in such manner at any time after delivery of such certificate, all or such portion of such amount shall be applied in accordance with this Section 9.12(c) without giving effect to this proviso within five (5) Business Days after such 90th day or the Issuer reasonably determining that such Net Proceeds are no longer intended to be or cannot be so applied as applicable. The Issuer will commence an Asset Sale Offer with respect to Excess Proceeds within fifteen (15) Business Days after receipt of Excess Proceeds by mailing, or delivering electronically if held by the Depository, the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. To the extent that the aggregate principal amount of the Securities (and such Other First Lien Debt, as the case may be) tendered pursuant to an Asset Sale Offer is less than the aggregate principal amount of the Securities that the Issuer has offered to purchase pursuant to an Asset Sale Offer, the Issuer may use any remaining Excess Proceeds for any purpose that is not prohibited by this Indenture. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

Notwithstanding anything to the contrary in this Section 9.12(c) or elsewhere in this Indenture, to the extent that (A) any or all of the Net Proceeds of any Asset Sale or Recovery Event by a Foreign Subsidiary are prohibited by any requirement of law from being loaned, distributed or otherwise transferred to the Issuer or any Domestic Subsidiary or materially adverse consequences to (including any material Tax incurred by) the Issuer or any of its Affiliates would result therefrom or (B) any or all of the Net Proceeds of any Asset Sale or Recovery Event by a Foreign Subsidiary are prohibited from being transferred to the Issuer for application in accordance with this Section 9.12(c) by any applicable organizational documents, joint venture agreement, shareholder agreement, or similar agreement or any other contractual obligation with an unaffiliated third party (including any agreement governing Indebtedness) that was not created in contemplation of such Asset Sale or Recovery Event, then in each case an amount equal to the portion of such Net Proceeds so affected will not be required to be applied as provided in this Section 9.12(c) so long as, but only so long as, such materially adverse consequences or prohibitions exist and once such materially adverse consequences or prohibitions are no longer applicable, an amount equal to such Net Proceeds will be promptly applied pursuant this Section 9.12(c) (the Issuer hereby agreeing to cause the applicable Subsidiary to promptly use commercially reasonable efforts to take all actions within the reasonable control of the Issuer that are reasonably required to eliminate or mitigate such materially adverse consequences or prohibitions, as the case may be).

120

The Issuer shall not, and shall not permit any Subsidiary to, enter into any agreement or instrument that by its terms restricts (x) the payment of dividends or other distributions or the making of cash advances to the Issuer or any Subsidiary that is a direct or indirect parent of such Subsidiary or (y) the granting of Liens by the Issuer or any Subsidiary to secure the Obligations, in each case other than those arising under any Note Document, except, in each case, restrictions existing by reason of:

(r) any encumbrances or restrictions imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of or similar arrangements to the contracts, instruments or obligations referred to in clauses (a) through (q) above; provided, that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements, refinancings or similar arrangements are, in the good faith judgment of the Issuer, no more restrictive with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions as contemplated by such provisions prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement, refinancing or similar arrangement.

(h) Level 3 Parent and the Issuer shall cause any Indebtedness of Level 3 Communications 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 Collateral Agent within thirty (30) days of the Incurrence of such Indebtedness; and

(i) Notwithstanding anything to the contrary contained herein, neither the Issuer nor Level 3 Communications (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 the term loans outstanding under the New Credit Agreement, the First Lien Notes and the Second Lien Notes outstanding at such time (after giving effect to any substantially concurrent repayment or prepayment of such term loans, such First Lien Notes or Second Lien Notes at the time of any reduction in the principal amount of the Loan Proceeds Note).

Section 9.16. [Reserved].

Section 9.17. Ratings. The Issuer shall use commercially reasonable efforts to obtain within sixty (60) days following the Issue Date and to maintain (a) public ratings from Moody’s and S&P for the Securities and (b) public corporate credit ratings and corporate family ratings from Moody’s and S&P in respect of the Issuer; provided, that in each case, that the Issuer and its subsidiaries shall not be required to obtain or maintain any specific rating.

Section 9.18. Authorizations and Consents of Governmental Authorities. Each of Level 3 Parent and the Issuer will endeavor, and cause each Regulated Grantor Subsidiary and each Regulated Guarantor Subsidiary to endeavor, in good faith using commercially reasonable efforts to (i) (A) cause the Collateral Permit Condition to be satisfied with respect to such Regulated Grantor Subsidiary and (B) cause the Guarantee Permit Condition to be satisfied with respect to such Regulated Guarantor Subsidiary, in each case at the earliest practicable date and (ii) obtain the material (as determined in good faith by the Issuer) authorizations and consents of federal and state Governmental Authorities required to cause any Subsidiary to become a Guarantor and

124

a Collateral Guarantor as required by this Section 9.18 and the Collateral and Guarantee Requirement. For purposes of this covenant, the requirement that Level 3 Parent or the Issuer 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 the Issuer 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 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 or Junior 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.

Section 9.19. Lumen Intercompany Loan. Each of Level 3 Parent and the Issuer will not, and will not permit any of their respective Subsidiaries to, amend, modify, grant any waivers under or supplement the Lumen Intercompany Loan, any documents entered into in connection therewith or any rights with respect to any of the foregoing in a manner that is adverse to the Holders; provided that upon (i) a separation of the mass market and enterprise businesses that entails a disposition or other transfer of either business to an unaffiliated third party for cash consideration at fair market value (as determined by the Issuer, a “Separation Event”) and (ii) the Issuer achieving a Secured Leverage Ratio of 3.15 prior to and pro forma for a Separation Event, the Issuer may, in its discretion, elect to terminate the Lumen Intercompany Loan.

Section 9.20. Business of the Issuer and the Subsidiaries; Etc. Each of Level 3 Parent and the Issuer will not, and will not permit any of their respective Subsidiaries to, permit any Material Assets that are owned by the Issuer, any Guarantor or any of their respective Subsidiaries to be transferred, sold, assigned, leased or otherwise disposed to (including pursuant to any Investment, Restricted Payment or other disposition), in one transaction or series of related transactions, to any Unrestricted Subsidiary.

Section 9.21. Limitation on Activities of Level 3 Parent and the Sister Subsidiaries. Neither Level 3 Parent nor any of its Sister Subsidiaries shall directly operate any material business; provided, that the following activities shall not constitute the operation of a business and shall in all cases be permitted:

125

(c) owning indirectly the Equity Interests of the Issuer’s Subsidiaries;

(d) entry into, and the performance of its obligations with respect to the Note Documents;

(e) Guarantees of Indebtedness permitted to be incurred hereunder by the Issuer and its Subsidiaries pursuant to Sections 9.08(b)(xii), (xx), (xxi) and (xxix);

(g) holding director and equityholder meetings, preparing organizational records and other organizational activities required to maintain its separate organizational structure or to comply with applicable requirements of law;

(h) the participation in tax, accounting and other administrative matters as a member of a consolidated group, including compliance with applicable requirements of law and legal, tax and accounting matters related thereto and activities relating to its officers, directors, managers and employees;

(i) in the case of Level 3 Parent, the holding of any cash and Cash Equivalents or other assets received in connection with permitted distributions or dividends received from, or permitted Investments or permitted dispositions made by any of its Subsidiaries or proceeds from the issuance of Equity Interests of Level 3 Parent; provided, that immediately after receipt thereof, such cash, Cash Equivalents or other assets are promptly contributed or otherwise transferred to the Issuer or a Subsidiary Guarantor or distributed as a Restricted Payment to the extent permitted by Section 9.11;

(j) the entry into and performance of its obligations with respect to the Parent Intercompany Note and any replacements thereof;

ARTICLE 10

REDEMPTION OF SECURITIES

Section 10.01. Right of Redemption.

(a) 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 to each Holder of Securities.

127

(b) Optional Redemption. At any time prior to March 22, 2027, the Securities may be redeemed, in whole or from time to time in part, at a Redemption Price equal to the sum of (A) 100.0% of the principal amount of the Securities redeemed, plus (B) the Make-Whole Premium as of the date of redemption, plus (C) accrued and unpaid interest, if any thereon, to, but excluding, the date of the redemption (subject to the right of Holders of Record on the relevant record date to receive interest due on the relevant Interest Payment Date).

At any time on or after March 22, 2027, the Securities may be redeemed, in whole or from time to time in part, at the Redemption Prices (expressed as percentages of principal amount of the Securities to be redeemed) set forth in the table below, plus accrued and unpaid interest, if any, thereon to, but excluding, 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), during the twelve-month period beginning on March 22 of each of the years indicated below:

Year |  | Percentage |
2027 |  |  | 105.375 | %
2028 |  |  | 102.688 | %
2029 |  |  | 100.000 | %

Any redemption described above or notice thereof may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of a corporate transaction or other event. 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 may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed or such notice or offer may be rescinded at any time in the Issuer’s discretion if the Issuer reasonably believes that any or all of such conditions will not be satisfied or waived.

(c) Applicable Premium. In the event of an Applicable Premium Trigger Event, the Issuer shall pay to the Trustee, for payment to the Holders of the Securities, the aggregate principal amount of the Securities being or required to be redeemed, repurchased or otherwise paid plus the Applicable Premium (without duplication).

Without limiting the generality of this Section 10.01, it is understood and agreed that if the Securities are accelerated as a result of an Event of Default (including, but not limited to Section 5.01(i), Section 5.01(j) or upon the occurrence or commencement of any bankruptcy or insolvency proceeding or other event pursuant to any applicable Debtor Relief Laws (including the acceleration of claims by operation of law)), the Securities that become due and payable shall include the Applicable Premium determined as of such date if the Securities were optionally redeemed pursuant to this Article 10 on such date, which shall become immediately due and payable by the Issuer and the Guarantors and shall constitute part of the Obligations as if the Securities were being optionally redeemed or repaid as of such date, in view of the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a good faith reasonable estimate and calculation of each beneficial holder’s lost profits and/or actual damages as a result thereof. The Applicable Premium shall also be

128

automatically and immediately due and payable if the Obligations are satisfied or released by foreclosure (whether by power of judicial proceeding or otherwise), deed in lieu of foreclosure, or by any other means in connection with an Event of Default described in the preceding sentence, including without limitation, under a plan of reorganization or similar manner in any bankruptcy, insolvency or similar proceeding. The Applicable Premium payable pursuant to this Indenture shall be presumed to be the liquidated damages sustained by each beneficial holder as the result of the early repayment or prepayment of the Securities (and not unmatured interest or a penalty) and the Issuer and the Guarantors agree that it is reasonable under the circumstances currently existing.

If the Applicable Premium becomes due and payable pursuant to this Indenture, the Applicable Premium shall be deemed to be principal of the Securities and Obligations under this Indenture and interest shall accrue on the full principal amount of the Securities (including the Applicable Premium). In the event the Applicable Premium is determined not to be due and payable by order of any court of competent jurisdiction, including, without limitation, by operation of the Bankruptcy Code, the Applicable Premium shall nonetheless constitute Obligations under this Indenture for all purposes hereunder.

THE ISSUER AND THE GUARANTORS EXPRESSLY WAIVE (TO THE FULLEST EXTENT THEY MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE APPLICABLE PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. The Issuer and the Guarantors expressly acknowledge and agree (to the fullest extent they may lawfully do so) that: (A) the Applicable Premium is reasonable and the product of an arm’s length transaction between sophisticated business people, ably represented by counsel, (B) the Applicable Premium shall each be payable under the circumstances described herein notwithstanding the then prevailing market rates at the time payment or redemption is made, (C) there has been a course of conduct between the beneficial holders, the Issuer and the Guarantors giving specific consideration in this transaction for such agreement to pay the Applicable Premium under the circumstances described herein, (D) the Applicable Premium shall not constitute unmatured interest, whether under section 502(b) of the Bankruptcy Code or otherwise, (E) the Applicable Premium does not constitute a penalty or an otherwise unenforceable or invalid obligation, (F) the Issuer and the Guarantors shall not challenge or question, or support any other person in challenging or questioning, the validity or enforceability of the Applicable Premium or any similar or comparable prepayment fee under the circumstances described herein, and the Issuer and the Guarantors shall be estopped from raising or relying on any judicial decision or ruling questioning the validity or enforceability of any prepayment fee similar or comparable to the Applicable Premium, and (G) the Issuer and the Guarantors shall be estopped hereafter from claiming differently than as agreed to in this paragraph. The Issuer and the Guarantors expressly acknowledge that its agreement to pay or guarantee the payment of the Applicable Premium to the beneficial holders as herein described are individually and collectively a material inducement to the beneficial holders to purchase the Securities. Any reference to “par” will include any Applicable Premium or accrued and unpaid interest that is added to principal theretofore so added. The parties acknowledge that the Applicable Premium provided for under this Indenture is believed to represent a genuine estimate of the losses that would be suffered by the beneficial holders as a result of the Issuer’s and the Guarantors’ breach of its obligations under this Indenture. The Issuer and the Guarantors waive, to the fullest extent permitted by law, the benefit of any statute affecting its liability hereunder or the enforcement hereof. Nothing in this paragraph is intended to limit, restrict, or condition any of the Issuer’s and the Guarantors’ obligations, rights or remedies hereunder.

129

Section 10.02. Applicability of Article. This Article 10 shall govern any redemption of the Securities pursuant to Section 10.01.

Section 10.03. Election to Redeem; Notice to Trustee. The election of the Issuer to redeem any Securities pursuant to Section 10.01 shall be evidenced by a Board Resolution of the Issuer delivered to the Trustee. The Issuer shall notify the Trustee of such Redemption Date and of the principal amount of Securities to be redeemed no less than 10 days (unless a shorter notice shall be satisfactory to the Trustee) prior to the delivery to the Holders of a notice of such redemption 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 10.04. 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 10.04. 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, by lot or by such other method as the Trustee shall deem appropriate and which may provide for the selection for redemption of portions of the principal of Securities 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 the minimum denomination of $1.00.

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 10.05. Notice of Redemption. Notice of redemption shall be given in the manner provided for in Section 1.06 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 3.10) to be redeemed and shall state:

(a) the Redemption Date,

(b) the Redemption Price and the amount of accrued interest to, but not including, the Redemption Date payable as provided in Section 10.07, if any,

(c) 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,

130

(d) 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,

(e) 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,

(f) 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 10.07) 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

(g) 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 10.06. 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 9.03) 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.

Section 10.07. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, 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.

131

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 10.08. Securities Redeemed in Part. Any Security held in physical form 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 9.02 (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 physical 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.

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 11.02 or Section 11.03 be applied to all Outstanding Securities upon compliance with the conditions set forth below in this Article 11.

Section 11.02. Defeasance and Discharge. Upon the Issuer’s exercise under Section 11.01 of the option applicable to this Section 11.02, 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 11.04 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 11.05 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 3.03, 3.06, 3.07, 9.02 and 9.03 and the Issuer’s rights under Section 10.01, (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 9.07) 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 11. Subject to compliance with this Article 11, the Issuer may exercise its option under this Section 11.02 notwithstanding the prior exercise of its option under Section

11.03 with respect to the Securities. If the Issuer exercises its option under this Section 11.02, (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 Subsidiary. Upon the Issuer’s exercise under Section 11.01 of the option applicable to this Section 11.02, all Liens on the Collateral securing the Indebtedness evidenced by the Securities shall be released and the Collateral Documents shall cease to be of further effect.

Section 11.03. Covenant Defeasance. Upon the Issuer’s exercise under Section 11.01 of the option applicable to this Section 11.03, the Issuer and each Guarantor shall be released from their obligations under any covenant contained in Sections 7.01(a)(ii), 7.03(a)(ii)(B)(3), (4) and (5), in Sections 7.04, 7.06, 9.05 and 9.18, Sections 9.07 through 9.22 and Section 12.01 and from the operation of Sections 5.01(f), (g), (h), (i), (j) and (k) (but, in the case of Sections 5.01(i) and (j), with respect only to Significant Subsidiaries) and from Section 9.22, 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. 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 5.01(c), (d), (e), (f), (g), (h), (i), (j) or (k) (but, in the case of Section 5.01(i) or (j), 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 11.03, (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 Subsidiary. Upon the Issuer’s exercise under Section 11.01 of the option applicable to this Section 11.03, all Liens on the Collateral securing the Indebtedness evidenced by the Securities shall be released and the Collateral Documents shall cease to be of further effect.

133

Section 11.04. Conditions to Defeasance or Covenant Defeasance. The following shall be the conditions to application of either Section 11.02 or Section 11.03 to the Outstanding Securities:

(a) The Issuer shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 6.08 who shall agree to comply with the provisions of this Article 11 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 Stated Maturity of the Securities: (i) money in an amount, or (ii) 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 (iii) 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 10.03, a notice of their election to redeem all of the Outstanding Securities at a future date in accordance with Article 10, which notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given effect in applying the foregoing.

(b) 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 5.01(i) and Section 5.01(j) 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).

(c) 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.

(d) In the case of an election under Section 11.02, 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 U.S. 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 U.S. federal income tax purposes as a result of such defeasance and will be subject to U.S. 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.

(e) In the case of an election under Section 11.03, 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 U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. 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.

(f) 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 11.02 or the covenant defeasance under Section 11.03 (as the case may be) have been complied with.

134

Section 11.05. Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 9.03 and any governing law, all money and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 11.05, the “Trustee”) pursuant to Section 11.04 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 11.04 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.

Anything in this Article 11 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 11.04 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 11.

Section 11.06. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 4.01 or 11.05 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 4.01, 11.02 or 11.03, 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.

135

ARTICLE 12

NOTE GUARANTEES

Section 12.01. Guarantees. Each Guarantor hereby unconditionally guarantees, jointly and severally, to each Holder and to the Trustee and Collateral Agent 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 12 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 and Collateral Agent 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 and Collateral Agent for the Obligations of any of them; (e) the failure of any Holder or the Trustee and Collateral Agent to exercise any right or remedy against any other guarantor of the Obligations; or (f) any change in the ownership of such Guarantor.

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 and Collateral Agent to any security held for payment of the Obligations.

Except as expressly set forth in Sections 7.05, 7.06, 9.14, 11.02, 11.03, 12.03 and 12.08, 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 Guarantee of the 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.

136

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 5 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 5, such Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section 12.01.

Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee and Collateral Agent or any Holder in enforcing any rights under this Section 12.01.

The Issuer shall cause each of its direct or indirect Subsidiaries that is not an Excluded Subsidiary and that guarantees or becomes a borrower under any First Lien Obligations to execute and deliver to the Trustee, within 30 days of such event (which such period will be automatically extended in 30 day increments so long as the Issuer uses commercially reasonable efforts), a supplemental indenture substantially in the form of Exhibit B hereto pursuant to which such Subsidiary will guarantee the Obligations. For the avoidance of doubt, no Excluded Subsidiary shall be required to guarantee the Obligations, become a party to the Collateral Agreement or any other Collateral Document or create Liens on its assets to secure the Obligations.

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) or Junior Lien Obligations 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.

137

Section 12.02. 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 Issue Date and the denominator of which shall be the aggregate net worth of the Issuer and all the Guarantors on the Issue Date (or, in the case of any Guarantor becoming a party hereto pursuant to Section 8.01, the date of the supplemental indenture executed and delivered by such Guarantor).

Section 12.03. Release of Guarantees. The Note Guarantee of a Guarantor that is a Subsidiary shall be automatically and unconditionally released:

(a) upon consummation of any transaction permitted hereunder if (x) resulting in such Guarantor ceasing to constitute a Subsidiary (including because such Subsidiary is designated an “Unrestricted Subsidiary”) or (y) in the case of any Guarantor that would not be required to be a Guarantor because it is, or has become, an Excluded Subsidiary as a result of a transaction following which it has become (or remains) a Subsidiary of the Issuer or a Guarantor, and upon notice to the Trustee (which failure to deliver such notice shall not effect the release without delivery of any instrument or any action by any party); provided that, any release pursuant to preceding clause (y) shall only be effective if:

(A) no Event of Default under Section 5.01(a), (b), (i) or (j) has occurred and is continuing or would result therefrom,

(B) at the time of such release (and after giving effect thereto), all outstanding Indebtedness of, and Investments in, such Subsidiary would then be permitted to be made in accordance with the relevant provisions of Sections 9.08 and 9.11 (for this purpose, with the Issuer being required to reclassify any such items made in reliance upon the respective Subsidiary being a Guarantor on another basis as would be permitted by such applicable Section) (and all items described above in this clause (B) shall thereafter be deemed recharacterized as provided above in this clause (B)),

(C) such Subsidiary shall not be (or shall be simultaneously released as) a guarantor (if applicable) with respect to the any First Lien Notes, Other First Lien Debt, Second Lien Notes, Permitted Consolidated Cash Flow Debt, Existing Unsecured Notes, Subordinated Indebtedness, any other Indebtedness secured by a Junior Lien or any Permitted Refinancing Indebtedness (and successive Permitted Refinancing Indebtedness) with respect to the foregoing; and

138

(D) the transaction resulting in such release is a legitimate business transaction and not for a “liability management transaction” as reasonably determined by the Issuer;

(b) [reserved],

(c) [reserved],

(d) if such Guarantor is (or immediately after being released from its Note Guarantee of the Securities will be) released from its Guarantee of all First Lien Obligations and Junior 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 Other Notes and is not otherwise required to Guarantee the Securities under this Indenture in accordance with Section 12.01,

(e) if the Issuer exercises the legal defeasance option or covenant defeasance option or effects a satisfaction and discharge of this Indenture, in each case in accordance with Article 11, or

(f) if such Guarantee was originally Incurred to permit such Guarantor to Incur or guarantee Indebtedness not otherwise permitted pursuant to Section 9.08 or Section 9.10 and the Indebtedness so Incurred or guaranteed (and any permitted refinancing Indebtedness thereof) has been repaid or discharged (provided that, after giving effect to such release, such Guarantor does not have any outstanding Indebtedness or guarantee that would violate Section 9.08 or Section 9.10 if such outstanding Indebtedness 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)).

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, shall 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 12.04. Successors and Assigns. This Article 12 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 Collateral Agent and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee and Collateral Agent, 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 12.05. 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 12 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 Collateral Agent 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 12 at law, in equity, by statute or otherwise.

139

Section 12.06. Modification. No modification, amendment or waiver of any provision of this Article 12, 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 Collateral Agent, 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 12.07. Execution of Supplemental Indenture for Future Guarantors.

(a) 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 12 and shall guarantee the Obligations. Concurrently with the execution and delivery of any such supplemental indenture by Level 3 Communications, Level 3 Communications 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 Communications 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 Communications is a legal, valid and binding obligation of Level 3 Communications, enforceable against Level 3 Communications in accordance with its terms. Each person then a Guarantor authorizes the Issuer to enter into such a supplemental indenture on its behalf.

Section 12.08. 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 Code, 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 12, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

ARTICLE 13

COLLATERAL AND SECURITY

Section 13.01. 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 interest on the Securities, according to the terms hereunder or

140

thereunder, and all other obligations of the Collateral Guarantors to the Holders or the Trustee or the Collateral Agent under the Note Documents are secured as provided in the Collateral Documents which the Collateral Guarantors have entered into simultaneously with the execution of this Indenture and will be secured as provided by the Collateral Documents hereafter delivered as required by this Indenture, which define the terms of the Liens that secure the Obligations, subject to the terms of the Intercreditor Agreements. The Trustee and the Issuer hereby acknowledge and agree that the 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 Collateral Documents. The Issuer and the Guarantors shall make all filings (including filings of continuation statements and amendments to Uniform Commercial Code financing statements that may be necessary to continue the effectiveness of such Uniform Commercial Code financing statements and filings with the United States Patent and Trademark Office and the United States Copyright Office of notices of grant of security interest in Intellectual Property) and take all other actions, in each case as are required by the Collateral Documents, to create, maintain, perfect, record, continue, enforce or protect (at the sole cost and expense of the Issuer and the Guarantors) the security interests created by the Collateral Documents in the Collateral (subject to the terms of the Intercreditor Agreements and the Collateral Documents) as a perfected security interest and within the time frames set forth therein subject to permitted Liens and the priority required by the Intercreditor Agreement and the other Collateral Documents.

(b) Each Holder, by its acceptance of a Securities, (i) consents and agrees to the terms of each Collateral Document (including, without limitation, the provisions providing for possession, use, release and foreclosure of Collateral), the First Lien/First Lien Intercreditor Agreement, the Multi-Lien Intercreditor Agreement, any Permitted Junior Intercreditor Agreement and any other Intercreditor Agreement 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 Collateral Agent to act on its behalf as “collateral agent” under this Indenture and the Collateral Documents, (iii) authorizes the Issuer to appoint the Collateral Agent to act on behalf of the Secured Parties as the Collateral Agent under this Indenture and the Collateral Documents, (iv) authorizes and directs the Collateral Agent to enter into the Collateral Documents to which it is or becomes a party, the First Lien/First Lien Intercreditor Agreement, the Multi-Lien Intercreditor Agreement, any Permitted Junior Intercreditor Agreement and any other Intercreditor Agreement and to perform its obligations and exercise its rights and powers thereunder in accordance therewith, (v) authorizes and empowers the Collateral Agent to bind the Holders and other holders of First Lien Obligations and Junior Lien Obligations as set forth in the Collateral Documents to which the Collateral Agent is a party and (vi) authorizes the Trustee to authorize the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Collateral Agent by the terms of the Collateral Documents and the Intercreditor Agreements, including for purposes of acquiring, holding, enforcing and foreclosing on 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 the Issuer or any Subsidiary to amend, waive or otherwise modify the Collateral Documents in accordance with their terms.

141

(c) Neither the Issuer nor any Guarantor will take or omit to take any action which would materially adversely affect or impair the validity or enforceability of the Liens in favor of the Collateral Agent on behalf of the Secured Parties 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.

(d) Subject to Article 6, neither the Trustee nor the Collateral Agent nor any of their respective officers, directors, employees, attorneys or agents will be responsible or liable for the existence, genuineness, value or protection of any Collateral, for the legality, validity, enforceability, effectiveness or sufficiency of the Collateral Documents, for the creation, perfection, priority, sufficiency or protection of any Lien securing First Lien Obligations, or for any defect or deficiency as to any such matters, or for any failure to demand, collect, foreclose or realize upon or otherwise enforce any of the Liens securing First Lien Obligations or the Collateral Documents or any delay in doing so.

(e) The Holders agree that the Collateral Agent shall be entitled to the rights, privileges, protections, immunities, indemnities and benefits provided to the Collateral Agent by this Indenture, the Intercreditor Agreements and the Collateral Documents. Furthermore, each Holder, by accepting a Security, consents to the terms of and authorizes and directs the Trustee (in each of its capacities) and the Collateral Agent to enter into and perform each of the First Lien/First Lien Intercreditor Agreement, the Multi-Lien Intercreditor Agreement, any Permitted Junior Intercreditor Agreement and any other Intercreditor Agreement and the Collateral Documents in each of its capacities thereunder.

(f) If the Issuer (i) Incurs Other First Lien Debt Obligations at any time when no intercreditor agreement is in effect or at any time when First Lien Obligations (other than the Securities) entitled to the benefit of the First Lien/First Lien Intercreditor Agreement are concurrently retired, and (ii) delivers to the Collateral Agent an Officers’ Certificate so stating and requesting the Collateral Agent to enter into an intercreditor agreement (on substantially the same terms as the First Lien/First Lien Intercreditor Agreement) in favor of a designated agent or representative for the holders of the Other First Lien Debt so Incurred, the Collateral Agent shall (and is hereby authorized and directed to) enter into such intercreditor agreement, bind the holders on the terms set forth therein and perform and observe its obligations thereunder.

(g) If the Issuer (i) Incurs Junior Lien Obligations at any time when no applicable intercreditor agreement is in effect or at any time when Indebtedness constituting Junior Lien Obligations entitled to the benefit of a Permitted Junior Intercreditor Agreement is concurrently retired, and (ii) delivers to the Collateral Agent and/or the Trustee, as applicable, an Officers’ Certificate so stating and requesting the Collateral Agent and/or the Trustee, as applicable, to enter into a Permitted Junior Intercreditor Agreement in favor of a designated agent or representative for the holders of the Indebtedness constituting Junior Lien Obligations so Incurred, the Collateral Agent and/or the Trustee, as applicable, shall (and each is hereby authorized and directed to) enter into such intercreditor agreement bind the holders on the terms set forth therein and perform and observe its obligations thereunder.

142

(h) At all times when the Trustee is not itself the Collateral Agent, the Issuer will, upon request, deliver to the Trustee copies of all Collateral Documents delivered to the Collateral Agent and copies of all documents delivered to the Collateral Agent pursuant to this Indenture and the Collateral Documents.

Section 13.02. New Collateral Guarantors. (a) [reserved].

(b) Substantially concurrently with any Subsidiary becoming a Guarantor pursuant to Section 12.01, the Issuer shall cause all of such Subsidiary’s assets (other than Excluded Property) to be subjected to a Lien securing the Obligations for the benefit of the Collateral Agent and thereafter shall take, or cause such Subsidiary to take, such actions as shall be necessary or reasonably requested by the Collateral Agent to grant and perfect or record such Lien, in each case to the extent contemplated by the Collateral Documents, all at the Issuer’s expense; provided that the Collateral in any event shall exclude Excluded Property. Notwithstanding anything to the contrary herein, no Regulated Subsidiary shall guarantee the Securities or pledge Collateral to secure such Guarantee prior to the satisfaction of the Guarantee Permit Condition or Collateral Permit Condition, as applicable.

(c) Subject to the limitations set forth in the Collateral Documents and the Intercreditor Agreements, 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 Collateral Agent may from time to time reasonably request, 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 Collateral Agent (including the payment of any fees and Taxes required in connection with the execution and delivery of the Collateral Documents, the granting of such security interests and the filing of any financing statements or other documents in connection therewith), in each case to the extent required by the Collateral Documents.

(d) Notwithstanding anything to the contrary in this Indenture or the 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 any 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 such First Lien Obligations.

Section 13.03. Collateral Agent. (a) The Issuer hereby appoints Wilmington Trust, National Association, to act on behalf of the Secured Parties as the Collateral Agent under this Indenture and each of the Collateral Documents and Intercreditor Agreements and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Collateral Documents, and Wilmington Trust, National Association agrees to act as such. The provisions of this Section 13.03 are solely for the benefit of the 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 Collateral Agent in accordance with the provisions of this Indenture, the Intercreditor Agreement and the Collateral Documents, and the exercise by the Collateral Agent of any rights or remedies set forth herein and therein shall be authorized and binding upon all

143

Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture or the Collateral Documents, the Collateral Agent shall not have any duties or responsibilities except those expressly set forth in this Indenture, the Collateral Documents to which it is party and in the Intercreditor Agreements. The 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 (as determined by a court of competent jurisdiction in a final, non-appealable order). The 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 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 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.

(b) Subject to the provisions of the Intercreditor Agreements and the Collateral Documents, the Trustee and the Collateral Agent are authorized and empowered to receive for the benefit of the Holders any funds collected or distributed under the Collateral Documents and Intercreditor Agreements to which the Collateral Agent or Trustee is a party and to make further distributions of such funds to Holders according to the provisions of this Indenture.

(c) Each Holder and other Secured Party hereby agrees that (A) it will be bound by and will take no actions contrary to the provisions of any such intercreditor agreement or other agreements or documents, (B) agrees that the Liens on the Collateral securing the Obligations shall be subject in all respects to the provisions thereof and (C) agrees that the Trustee and the Collateral Agent are authorized to take or refrain from taking any actions in accordance with the terms of an Intercreditor Agreement.

Without limiting the generality of the foregoing and subject to the Collateral Documents, the 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 Collateral Documents or Intercreditor Agreement that the Collateral Agent is required to exercise;

(iii) shall not, except as expressly set forth in the 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 Collateral Agent or any of its Affiliates in any capacity;

144

(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 or any other Collateral Document. The Collateral Agent shall be deemed not to have actual knowledge of any Event of Default unless and until written notice describing such Event of Default is given by the Trustee or the Issuer and received by a Responsible Officer of the Collateral Agent;

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

(vi) shall not be responsible or liable for creating, preserving, perfecting or validating the security interest granted to the Trustee and the Collateral Agent pursuant to the Collateral Documents or any lien and/or any filing, or recording or otherwise creating, perfecting, continuing or maintaining any lien or the perfection thereof.

(iii) Notwithstanding any other provisions of this Appendix A (other than the provisions set forth in Section 2.4), 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 2.4, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (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.

(v) In the case of a transfer of a beneficial interest in a Regulation S Global Security or a Rule 144A Global Security for an interest in an IAI Global Security, the transferee must furnish a signed letter substantially in the form of Exhibit 2 to the Trustee.

[FORM OF REVERSE SIDE OF SECURITY]

10.750% First Lien Notes due 2030

Capitalized terms used and not otherwise defined herein shall have the meanings assigned to such terms in the Indenture referred to below.

1. Interest

LEVEL 3 FINANCING, INC., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Issuer”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Issuer will pay interest semiannually on May 15 and November 15 of each year, commencing May 15, 2024, and on the maturity date. Interest on the Security will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from March 22, 2024. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

2. Method of Payment

The Issuer will pay interest 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. The Issuer will pay interest on the Securities on the maturity date to the persons entitled to the principal of the Securities. 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).

3. Paying Agent and Security Registrar

Initially, WILMINGTON TRUST, NATIONAL ASSOCIATION, 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.

15

4. Indenture

The Issuer issued the Securities under an Indenture dated as of March 22, 2024 (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 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 $678,367,000. 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 $678,367,000 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 Subsidiaries to, among other things, incur Indebtedness and create and incur Liens. The Indenture also imposes limitations on the ability of Level 3 Parent, the Issuer and their respective 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, Level 3 Parent has unconditionally guaranteed the Securities on an unsubordinated basis pursuant to the terms of the Indenture.

5. Optional Redemption

At any time prior to March 22, 2027, the Securities may be redeemed, in whole or from time to time in part, at a Redemption Price equal to the sum of (A) 100.0% of the principal amount of the Securities redeemed, plus (B) the Make-Whole Premium as of the date of the redemption, plus (C) accrued and unpaid interest, if any thereon, to, but excluding, the date of the redemption (subject to the right of Holders of Record on the relevant record date to receive interest due on the relevant Interest Payment Date).

At any time on or after March 22, 2027, the Securities may be redeemed, in whole or from time to time in part, at the Redemption Prices (expressed as percentages of principal amount of the Securities to be redeemed) set forth in the table below, plus accrued and unpaid interest, if any, thereon to, but excluding, 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), during the twelve-month period beginning on March 22 of each of the years indicated below:

16

Year |  | Percentage |
2027 |  |  | 105.375 | %
2028 |  |  | 102.688 | %
2029 |  |  | 100.000 | %

Any redemption described above or notice thereof may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of a corporate transaction or other event. 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 may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed or such notice or offer may be rescinded at any time in the Issuer’s discretion if the Issuer reasonably believes that any or all of such conditions will not be satisfied or waived.

Notwithstanding the foregoing, in connection with any tender offer for the Securities, including any offer to purchase Securities pursuant to Sections 9.07 and 9.12 of the Indenture, 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 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 paid to any holder in such tender offer payment) and (ii) par, plus accrued and unpaid interest (if any) thereon, to, but excluding the date of redemption or Redemption 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 date of redemption or Redemption Date.

6. Sinking Fund

The Securities are not subject to any sinking fund.

7. Notice of Redemption

Notice of redemption shall be given in the manner provided for in Section 1.06 of the Indenture 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.

17

8. Repurchase of Securities at the Option of Holders upon Change of Control Triggering Event; Offers to Purchase by Application of Excess Proceeds

(a) 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, but excluding, 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) as provided in, and subject to the terms of, the Indenture.

(b) After the Issuer or a Subsidiary consummates any Asset Sale, the Issuer may be required to purchase the Securities, as further specified in the Indenture.

9. Denominations; Transfer; Exchange

The Securities are in registered form without coupons in denominations of $1.00 and whole multiples of $1.00. 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 or co-registrar need not register the transfer of or exchange of any Security for a period beginning 15 days before the delivery of a notice of redemption or an offer to repurchase Securities 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, premium (if any), or interest remains unclaimed for two years, the Trustee or Paying Agent shall notify the Issuer and pay the money back to the Issuer at its written request after following specified procedures. After any such payment, Holders entitled to the money must look only to the Issuer and not to the Trustee for payment.

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 and/or Government Securities for the payment of principal, premium (if any) and interest on the Securities to redemption or maturity, as the case may be.

18

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 least a majority in principal amount of the Outstanding Securities. Subject to certain exceptions set forth in the Indenture, the Issuer, the Guarantors, the Trustee and the Collateral Agent may, at any time and from time to time, without notice to or consent of any Holders of Securities, (a) enter into one or more supplemental indentures and/or (b) amend, supplement or otherwise modify 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 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 Events 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 Collateral Agent in each case pursuant to the requirements of the Indenture; (vi) to secure the Securities; (vii) to comply with 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 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, the Collateral Documents and the Intercreditor Agreements, as and when permitted or required by the Indenture, the Collateral Documents or the Intercreditor Agreements; or (xi) to effect any provision of the Indenture or to make changes to the Indenture to provide for the issuance of Additional Securities. The intercreditor provisions of the Collateral Documents, the Intercreditor Agreements 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 Collateral Documents, the Intercreditor Agreements and any other applicable intercreditor agreement to designate Indebtedness as “First-Priority Obligations”, or as any other Indebtedness subject to the terms and provisions of such agreement.

19

14. Defaults and Remedies

Subject to certain exceptions set forth in the Indenture, 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 satisfactory to it in its sole discretion. 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. 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 principal or premium (if any) that has become due solely because of the acceleration.

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. However, the Trustee must comply with Section 6.08 of the Indenture.

16. No Recourse Against Others

A director, officer, employee, incorporator or stockholder, as such, of the Issuer or any Guarantor shall not 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 such person. 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 signs the certificate of authentication on the other side of this Security.

20

18. Abbreviations

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

19. Governing Law

THIS SECURITY 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.

20. CUSIP Numbers

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

21. Indenture Controls

The Securities are subject to all terms and provisions of the Indenture, and the Holders are referred to the Indenture for a statement of such terms and provisions.

Ladies and Gentlemen:

This certificate is delivered to request a transfer of $[_______] principal amount of the 10.750% First Lien Notes due 2030 (the “Securities”) of Level 3 Financing, Inc. (the “Company”).

Upon transfer, the Securities would be registered in the name of the new beneficial owner as follows:

Name:________________________

Address:______________________

Taxpayer ID Number:____________

The undersigned represents and warrants to you that:

1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the Securities, for investment purposes and not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Securities, and we invest in or purchase securities similar to the Securities in the normal course of our business. We, and any accounts for which we are acting, are each able to bear the economic risk of our or its investment.

2. We understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date that is one year after the later of the date of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction Termination Date”) only in accordance with the Restricted Notes Legend (as such term is defined in Appendix A of the indenture under which the Securities were issued) on the Securities

28

and any applicable securities laws of any state of the United States. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to Section 2.3(b) of Appendix A to the indenture under which the Securities were issued prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Securities for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Securities with respect to applicable transfers described in the Restricted Notes Legend to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to the Company and the Trustee.
