proceeds thereof, to (b) the sum of, without duplication, (x) Consolidated Cash Flow Available for Fixed Charges of the Borrower and the Borrower Restricted Subsidiaries for the four full fiscal quarters next preceding such proposed
Incurrence of Indebtedness for which consolidated financial statements are available and (y) Consolidated Cash Flow Available for Fixed Charges of Level 3 and the Sister Restricted Subsidiaries to the extent such Consolidated Cash Flow

giving pro forma effect to such Asset Dispositions, Investments, acquisitions, mergers or consolidations as if such Asset Dispositions, Investments, acquisitions, mergers or consolidations occurred on the first day of such period. For purposes of
this definition, whenever “pro forma” effect is to be given to any Asset Disposition, Investment, acquisition, merger or consolidation, the calculations shall be performed in accordance with Article 11 of Regulation S-X
promulgated under the Securities Act, as interpreted in good faith by the chief financial officer of Level 3, except that any such pro forma calculation may include operating expense reductions for such period attributable to the transaction to
which pro forma effect is being given (including, without limitation, operating expense reductions attributable to execution or termination of any contract, reduction of costs related to administrative functions, the termination of any employees or
the closing (or the approval by the Board of Directors of Level 3 of the closing) of any facility) that have been realized or for which all steps necessary for the realization of which have been taken or are reasonably expected to be taken

 ARTICLE II 
 The Credits 
 SECTION 2.01. Commitments; Loans and Borrowings. (a) Subject to the terms and
conditions set forth herein, each Lender agrees to make a Loan to the Borrower on the Effective Date in a principal amount equal to its Commitment. The Loans made on the Effective Date shall be ABR Loans or Eurodollar Loans as the Borrower shall
have elected in a notice delivered to the Administrative Agent not later than 11:00 a.m. New York City time, three Business Days prior to the Effective Date. The Commitments shall expire at 5:00 p.m. New York City time on the Effective Date, and
amounts paid or prepaid in respect of Loans may not be reborrowed. 
 (b) At the commencement of each Interest Period for any Eurodollar
Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000. At the time of the making of or conversion of a Borrowing to an ABR Borrowing, such Borrowing shall be in an aggregate
amount that is an integral multiple of $500,000 and not less than $1,000,000. Borrowings of more than one Type may be outstanding at one time; provided that there shall not at any time be more than a total of 10 Eurodollar Borrowings
outstanding at any one time. 
 SECTION 2.02. Funding of Loans. (a) Each Lender shall make the Loan to be made by it hereunder on
the Effective Date by wire transfer of immediately available funds by 12:00 noon, New York City time, to the account designated by the Administrative Agent for such purpose by notice to the Lenders. The Administrative Agent will make the Loans
available to the Borrower (i) by applying the amounts so received to the payment of the Existing Term Loans and all interest, fees and other amounts accrued or owing and not yet paid under the Existing Amended and Restated 
  

 42 








 Credit Agreement and (ii) after such application, by crediting the remainder of the amounts so received, in
immediately available funds, to the account of the Borrower designated by it for such purpose and previously communicated to the Administrative Agent. 
 (b) Unless the Administrative Agent shall have received notice from a Lender prior to the Effective Date that such Lender will not make the Loan to be made by it, the Administrative Agent may assume that such Lender
has made such Loan on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made the amount of its
Loan available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date
such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent
in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to the Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute
such Lender’s Loan. 
 (c) The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of
its obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make a Loan as required. 
 SECTION 2.03. Interest Elections. (a) The Borrower may elect to convert a Borrowing to a different Type or to continue a Borrowing and, in
the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be
allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. 
 (b) To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone (a) in the case of a request to convert or continue a Borrowing as a Eurodollar
Borrowing, not later than 11:00 a.m., New York City time, three Business Days before the date of the proposed conversion or continuation or (b) in the case of a request to convert or continue a Borrowing as an ABR Borrowing, not later than
11:00 a.m., New York City time, one Business Day before the date of the proposed conversion or continuation (each such notice being called an “Interest Election Request”). Each such telephonic Interest Election Request shall be
irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower. 
  

 43 








 (c) Each telephonic and written Interest Election Request shall specify the following information in
compliance with Section 2.01: 
 (i) the Borrowing to which such Interest Election Request applies and, if different
options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be
specified for each resulting Borrowing); 
 (ii) the effective date of the election made pursuant to such Interest Election
Request, which shall be a Business Day; 
 (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing; and 
 (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto
after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”. 
 If any such Interest
Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. 
 (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such
Lender’s portion of each resulting Borrowing. 
 (e) If the Borrower fails to deliver a timely Interest Election Request with respect to
a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. 
 (f) Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to elect to convert or continue any Borrowing if the
Interest Period requested with respect thereto would end after the Maturity Date. 
 SECTION 2.04. Repayment of Loans; Evidence of
Debt. (a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Maturity Date. 
 (b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the Indebtedness of the Borrower to such Lender
resulting from the Loans made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. 
 (c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest 
  

 44 








 Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable
from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof. 
 (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of
the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein (including any failure to record the making or repayment of any
Loan) shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. 
 (e)
Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to
such Lender and its registered assigns) in substantially the form set forth in Exhibit D. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to
Section 9.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). 
 SECTION 2.05. Prepayments. (a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in
part without premium (but subject to Section 2.10). 
 (b) When the aggregate amount of Excess Proceeds exceeds $10,000,000, the
Borrower shall within 15 days notify the Administrative Agent thereof and prepay the Loans in the amount of such Excess Proceeds without premium (but subject to Section 2.10) (as reduced by any portion thereof which has been rejected by
Declining Lenders pursuant to clause (e) below and specified in a notice delivered by the Administrative Agent to the Borrower). To the extent there are any remaining Excess Proceeds following the completion of the prepayment required hereunder
as a result of Lender elections not to accept such prepayment, the Borrower shall apply such Excess Proceeds to the repayment of other Indebtedness of the Borrower or any Restricted Subsidiary that is a Subsidiary of the Borrower, to the extent
permitted or required under the terms thereof. Any other remaining Excess Proceeds may be applied to any use as determined by Level 3 which is not otherwise prohibited by this Agreement, and the amount of Excess Proceeds shall be reset to zero.

 (c) Not fewer than 30 days prior to any payment or prepayment of any principal amount of the Loan Proceeds Note, the Borrower shall notify
the Administrative Agent thereof and shall, on the date of such payment or prepayment, subject to paragraph (e) below, prepay the Loans at a price equal to the principal amount of the Loans without premium (but subject to Section 2.10);
provided, however that (i) on the date of such payment or prepayment of the Loan Proceeds Note, the Administrative 
  

 45 








 Agent shall notify the Borrower of the required amount of such prepayment (as reduced by any portion thereof which has
been rejected by Declining Lenders pursuant to clause (e) below) and (ii) the Borrower shall immediately prepay the Loans in such amount in accordance with clause (e) below. 
 (d) Upon the occurrence of a Change of Control Triggering Event, the Borrower shall within 30 days of such occurrence notify the Administrative Agent
thereof and prepay the Loans not later than 30 Business Days following such notification; provided, however that (i) at the expiration of such 30 Business Day period, the Administrative Agent shall notify the Borrower of the
required amount of such prepayment (as reduced by any portion thereof which has been rejected by Declining Lenders pursuant to clause (e) below) and the Borrower shall immediately prepay the Loans in such amount in accordance with clause
(e) below and (ii) the Borrower shall also pay, on the date of such prepayment, to each Lender receiving such prepayment a fee equal to 1.00% of the principal amount of the Loans prepaid to such Lender. 
 (e) With respect to any proposed mandatory prepayment of the Loans pursuant to clause (b), (c) or (d) above, any Lender may, at its
option, elect not to accept such prepayment (any Lender making such election being a “Declining Lender”) as follows: each Declining Lender shall give written notice thereof to the Administrative Agent not later than 10:00 a.m. New
York City time on the date which is two Business Days prior to the date on which the Administrative Agent is required to notify the Borrower of the amount of the applicable prepayment pursuant to clause (b), (c) or (d) above. On the
date of prepayment, an amount equal to that portion of the Loan then to be prepaid (less the amount thereof that would otherwise be payable to Declining Lenders) shall be paid to the Lenders that are not Declining Lenders in accordance with
subsection (f) below. In the event that the Administrative Agent has not, with respect to any mandatory prepayment, received a notice from a Lender in accordance with this clause (e), such Lender shall be deemed to have waived its rights
under this clause (e) to decline receipt thereof. 
 (f) The Borrower (or Level 3 on its behalf) shall notify the Administrative
Agent by telephone (confirmed by telecopy) of any prepayment hereunder not later than 1:00 p.m., New York City time, two Business Days before the date of prepayment or such lesser period as may be acceptable to the Administrative Agent. Each
such notice shall be irrevocable and shall specify the prepayment date, the principal amount to be prepaid and, in the case of a mandatory prepayment, a reasonably detailed calculation of the amount of such prepayment. Promptly following receipt of
any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.07. If any prepayment pursuant to this Section is made by the
Borrower other than on the last day of the Interest Period applicable to any prepaid Eurodollar Loans, the Borrower shall also pay to each Lender (other than any Declining Lender) on the date of such prepayment any amount owing to such Lender
pursuant to Section 2.10. 
  

 46 








 SECTION 2.06. Fees. (a) Level 3 and the Borrower agree to pay to the Administrative
Agent, for its own account, fees payable in the amounts and at the times separately agreed upon by the Borrower and the Administrative Agent. 
 SECTION 2.07. Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin. The Loans comprising each Eurodollar Borrowing shall bear interest at the LIBO Rate
for the Interest Period for such Borrowing plus the Applicable Margin. 
 (b) Notwithstanding the foregoing, if any principal of or interest
on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum
equal to (i) in the case of overdue principal of any Loan, 2.00% per annum plus the rate otherwise applicable to such Loan as provided in paragraph (a) of this Section or (ii) in the case of any other amount, 2.00% per annum
plus the rate that would at the time be applicable to an ABR Loan as provided in paragraph (a) of this Section. 
 (c) Accrued interest
on the Loans shall be payable in arrears on each Interest Payment Date; provided that (i) interest accrued pursuant to paragraph (b) of this Section shall be payable on demand and (ii) in the event of any repayment or
prepayment of the Loans, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment. 
 (d) All interest hereunder shall be computed on the basis of the actual number of days elapsed in a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first
day but excluding the last day). The applicable LIBO Rate or Alternate Base Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error. 
 SECTION 2.08. Alternate Rate of Interest. If, prior to the commencement of any Interest Period for a Eurodollar Borrowing, the Administrative
Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the LIBO Rate for such Interest Period, then the Administrative Agent shall give notice thereof to
Level 3 and the Lenders by telephone or telecopy as promptly as practicable thereafter, whereupon each Eurodollar Loan shall automatically, on the last day of the current Interest Period for such Eurodollar Loan, convert into an ABR Loan and
the obligations of the Lenders to make Eurodollar Loans shall be suspended until the Administrative Agent notifies Level 3 and the Lenders that the circumstances giving rise to such notice no longer exist. 
 SECTION 2.09. Increased Costs. (a) If any Lender shall notify the Administrative Agent and Level 3 at any time that Eurocurrency Reserve
Requirements are, or are scheduled to become, effective and that such Lender is or will be generally subject to such Eurocurrency Reserve Requirements and will, as a result, incur additional costs, then such Lender shall, for each day from the later
of the date of such notice and 
  

 47 








 the date on which such Eurocurrency Reserve Requirements become effective, be entitled to additional interest on each
Eurodollar Loan made by it at a rate per annum determined for such day (rounded upward to the nearest 100th of 1%) equal to the remainder obtained by subtracting (i) the LIBO Rate for such Eurodollar Loan from (ii) the rate obtained by
dividing such LIBO Rate by a percentage equal to 100% minus the Eurocurrency Reserve Requirements then-applicable to such Lender. Such additional interest will be payable in arrears to the Administrative Agent, for the account of such Lender, on
each Interest Payment Date relating to such Eurodollar Loan and on any other date when interest is required to be paid hereunder with respect to such Loan. Any Lender giving a notice under this paragraph (a) shall promptly withdraw such notice
(by written notice of withdrawal given to the Administrative Agent and Level 3) in the event Eurocurrency Reserve Requirements cease to apply to it or the circumstances giving rise to such notice otherwise cease to exist. 
 (b) If any Change in Law shall: 
 (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by any Lender (except any Eurocurrency Reserve Requirement); or 

(ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans of such
Lender; 
 and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan or to reduce the
amount of any sum received by such Lender, then Level 3 and the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. This Section shall not
apply to any additional costs or reductions relating to Taxes, which are governed by Section 2.11. 
 (c) If any Lender determines that
any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the
Loans made by such Lender to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s
holding company with respect to capital adequacy), then from time to time Level 3 and the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such
reduction suffered. 
 (d) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding
company, as the case may be, as specified in paragraph (b) or (c) of this Section shall be delivered to Level 3 and shall be conclusive absent manifest error. Level 3 and the Borrower, as the case may be, shall pay such Lender
the amount shown as due on any such certificate within 10 days after receipt thereof. 
  

 48 








 (e) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not
constitute a waiver of such Lender’s right to demand such compensation; provided that Level 3 and the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more
than 180 days prior to the date that such Lender notifies Level 3 of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the
Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof. 
 (f) The provisions of Section 2.09(a) and (c) shall only be available to Lenders regulated by Federal banking authorities. 
 SECTION 2.10. Break Funding Payments. In the event of (a) any payment of any principal of any Eurodollar Loan other than on the last day of
an Interest Period applicable thereto (including as a result of an Event of Default), (b) the failure to borrow or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (c) the assignment of any
Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by Level 3 pursuant to Section 2.13, then, in any such event, Level 3 and the Borrower, as applicable, shall compensate each
Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed not to include any lost profit (including loss of Applicable Margin) and shall be deemed to
include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such Loan had such event not occurred at the LIBO Rate that is or would have been applicable
to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such
Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount
and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to Level 3 and shall be conclusive absent
manifest error. Level 3 or the Borrower, as applicable, shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 
 SECTION 2.11. Taxes. (a) Any and all payments by or on account of the obligations of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 
  

 49 








 (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in
accordance with applicable law. 
 (c) Level 3 and the Borrower shall indemnify the Administrative Agent and each Lender, within 10 days
after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower
hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with
respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to Level 3 or the
Borrower by a Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. 
 (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent reasonably satisfactory evidence of such payment and the
original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment; provided however in no case shall the Borrower be required to deliver documentation not normally issued by such Governmental Authority.

 (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which
the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower and Level 3 (with a copy to the Administrative Agent), at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower and Level 3 as will permit such payments to be made without withholding or at a reduced rate. 
 SECTION 2.12. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) The Borrower shall make each payment required to be made by it
hereunder or under any other Loan Document (whether of principal, interest or fees, or of amounts payable under Section 2.09, 2.10 or 2.11, or otherwise) prior to 1:00 p.m., New York City time, on the date when due, in immediately
available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating
interest thereon. All such payments shall be made to the Administrative Agent at its offices at Merrill Lynch World Headquarters, North Tower, World Financial Center, New York, New York 10281-1201, except that payments pursuant to Sections 2.09,
2.10, 2.11 and 9.03 shall be made directly to the Persons entitled thereto and payments pursuant to other Loan Documents shall be made 
  

 50 








 to the Persons specified therein. The Administrative Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment under any Loan Document shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding
Business Day and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments under each Loan Document shall be made in dollars. 
 (b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees
then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and
(ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties. 
 (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on
any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion
shall purchase (for cash at face value) participations in the Loans of the other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of
and accrued interest on their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase
price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to Level 3 or any Subsidiary or Affiliate thereof (as to which the
provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation in an obligation owed by it pursuant to the
foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 
 (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute
to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with
interest thereon, for each day from and including the date such amount is distributed to it to but excluding the 
  

 51 








 date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by
the Administrative Agent in accordance with banking industry rules on interbank compensation. 
 (e) If any Lender shall fail to make any
payment required to be made by it hereunder, then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to
satisfy such Lender’s obligations until all such unsatisfied obligations are fully paid. 
 SECTION 2.13. Mitigation Obligations;
Replacement of Lenders. (a) If any Lender requests compensation under Section 2.09, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to
Section 2.11, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates
if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.09 or 2.11, as the case may be, in the future and (ii) would not subject such Lender to any
unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Level 3 and the Borrower hereby agree to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

 (b) If any Lender requests compensation under Section 2.09 (other than paragraph (a) of such Section), or if the Borrower is
required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.11, if any Lender defaults in its obligation to fund Loans hereunder or under the circumstances contemplated
by Section 9.02(d), Level 3 may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions
contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that
(i) Level 3 shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of
its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or Level 3 or the Borrower (in the case of all other
amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.09 or payments required to be made pursuant to Section 2.11, such assignment will result in a reduction in such compensation
or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling Level 3 to require such assignment and delegation cease
to apply.

 ARTICLE III 
 Representations and Warranties 
 On and as of the Effective Date, each of Level 3 and the Borrower
represents and warrants to the Lenders that: 
 SECTION 3.01. Organization; Powers. Each of Level 3, the Borrower and each Material
Subsidiary of Level 3 is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except where the failure to
do so, individually or in the aggregate, would not constitute or result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required. 
 SECTION 3.02. Authorization; Enforceability. The Transactions to be entered into by each Loan Party on the Effective Date are within such Loan
Party’s powers and have been duly authorized by all necessary corporate or other action and, if required, stockholder or member action. This Agreement has been duly executed and delivered by Level 3 and the Borrower and constitutes, and each
other Loan Document to which any Loan Party is to be a party, when executed by and delivered by such Loan Party, will constitute, a legal, valid and binding obligation of such Loan Party, enforceable in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 
 SECTION 3.03. Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing
with, or any other action by, any Governmental Authority, except such as are contemplated to be taken to satisfy the Guarantee Permit Condition and the Collateral Permit Condition and such as have been obtained or made and are in full force and
effect and filings necessary to perfect Liens created under the Loan Documents, (b) will not violate the charter, by-laws or other organizational documents of Level 3 or any of the Loan Parties and will not violate, except for any
violation which would not constitute or result in a Material Adverse Effect, (i) any applicable law or regulation of a type typically applicable to transactions of the type contemplated by the Transactions, (ii) any material order of any
Governmental Authority, (c) will not violate the Parent’s Indentures, the Subordinated Indentures or the Financing Inc. Indentures and (d) will not result in the creation or imposition of any Lien on any material assets of
Level 3, the Borrower or any Subsidiary of Level 3, except Liens created under the Loan Documents. 
 SECTION 3.04. Financial
Condition; No Material Adverse Change. (a) The Lenders have been given access to Level 3’s consolidated balance sheet and statements of income, stockholders equity and cash flows as of and for the fiscal year ended December 31,
2006, reported on by KPMG LLP, an independent public accounting firm. Such financial statements present fairly in all material respects the financial position and results of operations and cash flows of Level 3 and its consolidated Subsidiaries as
of such date and for such period in accordance with GAAP. 
  

 53 








 (b) Except for the Disclosed Matters, after giving effect to the Transactions, none of Level 3 or its
Subsidiaries will have, as of the Effective Date, any contingent liabilities, unusual long-term commitments or unrealized losses which would constitute or result in a Material Adverse Effect. 
 (c) Except as may be disclosed in Level 3’s reports and filings under the Exchange Act filed or furnished since January 1, 2007 and prior to
March 12, 2007 and available on the Securities and Exchange Commission’s website on the internet at www.sec.gov prior to the Effective Date, since December 31, 2006, there has been no material adverse change in the business, assets,
operations or condition, financial or otherwise, of Level 3 and its Subsidiaries, taken as a whole which would constitute or result in a Material Adverse Effect. 
 SECTION 3.05. Properties. Each of Level 3, the Borrower and each Subsidiary of Level 3 has good title to, or valid leasehold interests in, all its real and personal property material to its business,
except for minor defects in title that do not interfere with its ability to conduct its business as currently conducted or to utilize such properties for their intended purposes and such defects as would not constitute or result in a Material
Adverse Effect. 
 SECTION 3.06. Litigation and Environmental Matters. (a) There are no actions, suits or proceedings by or
before any arbitrator or Governmental Authority pending against or, to the knowledge of Level 3 or the Borrower, threatened against or affecting Level 3, the Borrower or any Material Subsidiary of Level 3 (i) as to which there is
a reasonable possibility of an adverse determination and that, if adversely determined, would, individually or in the aggregate, constitute or result in a Material Adverse Effect (other than the Disclosed Matters) or (ii) that involve any of
the Loan Documents or the Transactions. 
 (b) Except for the Disclosed Matters and except with respect to any other matters that,
individually or in the aggregate, would not constitute or result in a Material Adverse Effect, none of Level 3, the Borrower or any of the Subsidiaries of Level 3 (i) has failed to comply with any Environmental Law or to obtain, maintain or
comply with any permit, license or other approval required under any Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or
(iv) knows of any basis for any Environmental Liability. 
 SECTION 3.07. Compliance with Laws and Agreements. Level 3, the
Borrower and each of the Subsidiaries of Level 3 is in compliance with all laws, regulations and orders of any Governmental Authority applicable to it or its property and all indentures, agreements and other instruments binding upon it or its
property, except where the failure to do so, individually or in the aggregate, would not constitute or result in a Material Adverse Effect. No Default has occurred and is continuing. 
  

 54 








 SECTION 3.08. Investment Company Status. Neither Level 3 nor any of the Loan Parties is an
“investment company” or is controlled by an entity that is an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940. 
 SECTION 3.09. Taxes. Level 3, the Borrower and each of the Material Subsidiaries of Level 3 has timely filed or caused to be filed all tax returns
and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which Level 3, the Borrower or such
Subsidiary, as applicable, has set aside on its books adequate reserves or (b) to the extent that the failure to do so would not constitute or result in a Material Adverse Effect. 
 SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, would constitute or result in a Material Adverse Effect. The present value of all accumulated benefit obligations under each Plan (based on the assumptions used for purposes of Statement of Financial
Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of such Plan by an amount that would constitute or result in a Material Adverse
Effect, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent
financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans by an amount that would constitute or result in a Material Adverse Effect. 
 SECTION 3.11. Disclosure. None of the reports, financial statements, certificates or information furnished by or on behalf of any Loan Party to
the Administrative Agent or any Lender in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or thereunder (as modified or supplemented by other information so furnished), contains any material
misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 
 SECTION 3.12. Subsidiaries. Schedule 3.12 sets forth the name of, and the ownership interest of Level 3 in, each domestic Material
Subsidiary. 
 SECTION 3.13. Insurance. Schedule 3.13 sets forth a description of all insurance maintained by or on behalf of
Level 3, the Borrower and the Material Subsidiaries of Level 3 as of the Effective Date. To the knowledge of Level 3, such insurance complies with the requirements of Section 5.07. 
 SECTION 3.14. Labor Matters. As of the Effective Date, there are no material strikes, lockouts or slowdowns against Level 3, the Borrower or any
Subsidiary of Level 3 pending or, to the knowledge of Level 3 or the Borrower, threatened which would constitute or result in a Material Adverse Effect. The consummation of the 
  

 55 








 Transactions will not give rise to any right of termination or right of renegotiation on the part of any union under any
collective bargaining agreement to which Level 3, the Borrower or any Subsidiary of Level 3 is bound other than any right which would not constitute or result in a Material Adverse Effect. 
 SECTION 3.15. Intellectual Property. Each of Level 3, the Borrower and the Material Subsidiaries of Level 3 owns, or is licensed to use, all
trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by Level 3, the Borrower and each Material Subsidiary of Level 3, to the knowledge of Level 3 or the Borrower, does not
infringe upon the rights of any other Person except for any such infringements that, individually or in the aggregate, would not constitute or result in a Material Adverse Effect. 
 SECTION 3.16. Security Interests. (a) When executed and delivered, (i)(A) the Collateral Agreement will be effective to create in favor of
the Collateral Agent for the benefit of the Secured Parties a valid and enforceable security interest in the Collateral (as defined in the Collateral Agreement) and (B) the Loan Proceeds Note Collateral Agreement will be effective to create in
favor of the Secured Party (as defined in the Loan Proceeds Note Collateral Agreement) a valid and enforceable security interest in the Collateral (as defined in the Loan Proceeds Note Collateral Agreement), (ii) when the portion of the
Collateral (as defined in the Collateral Agreement) constituting certificated securities (as defined in the Uniform Commercial Code), is delivered to the Collateral Agent, together with instruments of transfer duly endorsed in blank, the Collateral
Agreement will constitute, under applicable Federal and State law, a fully perfected first priority Lien on, and security interest in all right, title and interest of the pledgors thereunder in such Collateral, prior and superior in right to any
other Person and (iii) when financing statements in sufficient form are filed in the offices specified in the Effective Date Perfection Certificate or in the Effective Date Loan Proceeds Note Perfection Certificate, as the case may be, each of
the Collateral Agreement and the Loan Proceeds Note Collateral Agreement will constitute, under applicable Federal and State law, a fully perfected (except with respect to undisclosed Commercial Tort Claims (as defined in the Collateral Agreement))
Lien on, and security interest in all right, title and interest of the grantors thereunder in such Collateral, to the extent perfection can be obtained by filing Uniform Commercial Code financing statements, other than the Intellectual Property (as
defined in the Security Agreements) in which a security interest may be perfected by filing, recording or registering a security agreement, financing statement or analogous document in the United States Patent and Trademark Office or the United
States Copyright Office, as applicable, in each case (other than with respect to undisclosed Commercial Tort Claims (as defined in the Collateral Agreement)) prior and superior in right to any other Person to the extent perfection can be obtained by
filing Uniform Commercial Code financing statements, other than with respect to the rights of Persons pursuant to Liens expressly permitted by Section 6.05. 
 (b) When the Collateral Agreement or memorandum thereof is filed in the United States Patent and Trademark Office and the United States Copyright Office, the security interest created thereunder shall constitute a
fully perfected Lien on, and security interest in, all right, title and interest of the Loan Parties in the Intellectual Property (as 
  

 56 








 defined in the Collateral Agreement) in which a security interest may be perfected by filing, recording or registering a
security agreement, financing statement or analogous document in the United States Patent and Trademark Office or the United States Copyright Office, as applicable, in each case prior and superior in right to any other Person, other than with
respect to the rights of Persons pursuant to Liens expressly permitted by Section 6.05 (it being understood that subsequent recordings in the United States Patent and Trademark Office and the United States Copyright Office may be necessary to
perfect a lien on registered trademarks, trademark applications and copyrights acquired by the Loan Parties after the date hereof). 
 SECTION 3.17. FCC Compliance. (a) Level 3, the Borrower and each Subsidiary of Level 3 are in compliance with the Communications Act except where the failure to be in compliance would not constitute or result in a Material
Adverse Effect. 
 (b) To the knowledge of Level 3, there is no investigation, notice of apparent liability, violation, forfeiture or
other order or complaint issued by or before the FCC, or any other proceedings of or before the FCC, affecting it, the Borrower or any Subsidiary of Level 3 which would constitute or result in a Material Adverse Effect. 
 (c) No event has occurred which (i) results in, or after notice or lapse of time or both would result in, revocation, suspension, adverse
modifications, non-renewal, impairment, restriction or termination of, or order of forfeiture with respect to, any License in any respect which would constitute or result in a Material Adverse Effect or (ii) affects or would reasonably be
expected in the future to affect any of the rights of Level 3, the Borrower or any Subsidiary of Level 3 under any License held by Level 3, the Borrower or such Subsidiary in any respect which would constitute or result in a Material
Adverse Effect. 
 (d) Level 3, the Borrower and each Subsidiary of Level 3 have duly filed in a timely manner all material
filings, reports, applications, documents, instruments and information required to be filed by it under the Communications Act, and all such filings were when made true, correct and complete in all respects except where the failure to do so would
not constitute or result in a Material Adverse Effect. 
 SECTION 3.18. Qualified Credit Facility; Senior Indebtedness. The Loans and
the other Obligations constitute a “Qualified Credit Facility” as defined in the Financing Inc. Indentures. The Loans and the other Obligations constitute “Senior Indebtedness” of the Parent, the Borrower and each other Loan
Party for purposes of any Indebtedness of the Parent, the Borrower or such other Loan Party that by its terms is subordinated to any other Indebtedness of such Person. 
 SECTION 3.19. Solvency. Immediately following the making of the Loans on the Effective Date and after giving effect to the application of the proceeds of the Loans, (a) the fair value of the assets of
Level 3 and its Subsidiaries on a consolidated basis, at a fair valuation, will exceed their debts and liabilities, subordinated, contingent or otherwise; (b) the present fair saleable value of the property of Level 3 and its Subsidiaries,
on a consolidated basis, will be greater than the amount that will be required 
  

 57 








 to pay the probable liability of their debts and other liabilities, subordinated, contingent or otherwise, as such debts
and other liabilities become absolute and matured; (c) Level 3 and its Subsidiaries on a consolidated basis, will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become
absolute and matured; and (d) Level 3 and its Subsidiaries, on a consolidated basis, will not have unreasonably small capital with which to conduct the business in which they are engaged as such business is now conducted and is proposed to
be conducted following the Effective Date.

satisfactory to the Collateral Agent) have been made under the Uniform Commercial Code or otherwise that are required in order for the Collateral Agent to continue at all times following such change to have a valid, legal and perfected security
interest in all the Collateral. Each of Level 3 and the Borrower also agrees promptly to notify the Collateral Agent if any material portion of the Collateral is damaged or destroyed.

to, do or cause to be done all things necessary to preserve, renew and keep in full force and effect its legal existence and its rights, charter and statutory, except where the failure to do so would not constitute or result in a Material Adverse
Effect; provided that the foregoing shall not prohibit any merger, consolidation, liquidation or dissolution permitted under Section 6.13. 
 SECTION 5.05. Payment of Taxes. Each of Level 3 and the Borrower will, and will cause each Subsidiary of Level 3 to, pay its material Tax obligations, before the same shall become delinquent or in default,

Level 3 may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent Level 3 from
discontinuing the maintenance of any of such properties if such discontinuance is, in the judgment of Level 3, desirable in the conduct of its business or the business of any Subsidiary of Level 3 and not disadvantageous in any material
respect to the Lenders. 
 SECTION 5.07. Insurance. Each of Level 3 and the Borrower will, and will cause each of the Restricted
Subsidiaries to, keep all of their respective properties

damage to the extent that property of a similar character is usually insured by companies similarly situated and owning like properties. Level 3 will furnish to the Lenders, upon the reasonable request of the Administrative Agent, but not more
than once during any calendar year unless a Default or an Event of Default has occurred and is continuing, information in reasonable detail as to the insurance so maintained. 
 SECTION 5.08. Casualty and Condemnation. Level 3 (a) will furnish to the Administrative Agent prompt written notice of any casualty or
other insured damage to any portion of any Collateral or the commencement of any action or proceeding for the taking of any Collateral or any part thereof or interest therein under power of eminent domain or by condemnation or similar proceeding in
each case only where Level 3 estimates in good faith that the expected proceeds from insurance, condemnation awards or otherwise will exceed $25,000,000 and (b) will ensure that the Net Available Proceeds of any such event (whether in the
form of insurance proceeds, condemnation awards or otherwise) are collected and applied in accordance with the applicable provisions of this Agreement and the Security Documents. Level 3 will act in good faith to collect or compromise all such
amounts. 
 SECTION 5.09. Annual Information Meeting. The Borrower shall, at the request of the Required Lenders, hold an annual

 SECTION 5.10. Compliance with Laws. Each of Level 3 and the Borrower will, and will cause each of the Restricted Subsidiaries of Level 3
to, comply with all laws (including the Communications Act), rules, regulations and orders of any Governmental Authority applicable to it or its property (including obligations under Licenses), except where the failure to do so, individually or in
the aggregate, would not constitute or result in a Material Adverse Effect. 
 SECTION 5.11. Use of Proceeds. The proceeds of the
Loans will be (a) used to refinance the Existing Term Loans and (b) to the extent of the remaining proceeds, advanced by the Borrower to Level 3 LLC against delivery of the Loan Proceeds Note. No part of the proceeds of the Loans will be
used, whether directly or indirectly, for any purpose that entails a violation of any of the Regulations of the Board, including Regulations T, U and X. 
 SECTION 5.12. Guarantee and Collateral Requirement; Further Assurances. Level 3 and the Borrower will cause the Guarantee and Collateral Requirement to be and remain satisfied at all times. Without limiting the
foregoing, Level 3 and the Borrower will, and will cause each Subsidiary of Level 3 to, execute any and all documents, financing statements, agreements and instruments, and take all other actions (including the filing of financing statements and
other documents), which shall be required under any applicable United States law, or which the Collateral Agent may reasonably request, to effectuate the transactions contemplated by the Loan Documents or 
  

 63 








 to grant, preserve, protect or perfect the Liens created or intended to be created by the Loan Documents or the validity
or priority of any such Lien, all at the expense of the Loan Parties. Level 3 and the Borrower also agree to provide to the Collateral Agent, from time to time upon request, evidence reasonably satisfactory to the Collateral Agent as to the
perfection of the Liens created or intended to be created by the Loan Documents. 
 SECTION 5.13. Guarantee Permit Condition and
Collateral Permit Condition. (a) Each of Level 3 and the Borrower will endeavor, and cause each Regulated Grantor and each Regulated Guarantor 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 and (B) cause the Guarantee Permit Condition to be satisfied with respect to such Regulated Guarantor, in each case at the earliest practicable date and
(ii) obtain the material (as determined in good faith by the General Counsel of Level 3) authorizations and consents of Federal and State Authorities required to cause any Restricted Subsidiary to become a Guarantor as required by Sections
6.01(d) and 6.02(d). For purposes of this Section, the requirement that Level 3, the Borrower or any Subsidiary of Level 3 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 shall determine in good faith to be adverse or materially burdensome.
Upon the reasonable request of Level 3 or the Borrower, the Administrative Agent and the Lenders will cooperate with Level 3 and the Borrower as necessary to enable them to comply with their obligations under this Section. 
 (b) If Level 3 shall determine that Level 3 LLC is able, consistent with applicable law, to create Liens on any Collateral owned by it and located in any
jurisdiction located in the United States to secure the Loan Proceeds Note prior to the satisfaction by it of the Collateral Permit Condition, it will cause Level 3 LLC promptly to create and perfect such Liens on terms and under documentation
reasonably satisfactory to Level 3 and the Collateral Agent.

of default thereunder), in each case on or prior to the Maturity Date, and (2) does not permit redemption or other retirement (including pursuant to an offer to purchase made by Level 3 but excluding through conversion into capital stock

Restricted Subsidiary ceases to be a Restricted Subsidiary, the provisions of this clause (vi) shall no longer be 
  

 66 








 applicable to such Indebtedness and such Indebtedness shall be deemed to have been Incurred by the issuer
thereof at the time of such transfer, conveyance or other disposition or when such Restricted Subsidiary ceases to be a Restricted Subsidiary; and (C) the payment obligation of (i) such Indebtedness (if clause (A) above applies)

Indebtedness being refinanced in accordance with this covenant, (1) the Person that Incurs the refinancing Indebtedness pursuant to this clause (viii) shall be a Guarantor and a Loan Proceeds Note Guarantor and (2) if the
Indebtedness to be refinanced is subordinated to the Loan Proceeds Note Guarantee of such Loan Proceeds Note Guarantor or the Guarantee of the Obligations of such Guarantor, the refinancing Indebtedness shall be subordinated to the same extent to
the Loan Proceeds Note Guarantee of the Loan Proceeds Note Guarantor or the Guarantee of the Obligations of such Guarantor, as the case may be, Incurring such refinancing Indebtedness, (B) the refinancing Indebtedness shall not be senior in
right of payment to the Indebtedness that is being refinanced and (C) in the case of any refinancing of Indebtedness Incurred pursuant to paragraph (a) above or 
  

 67

Indebtedness Incurred pursuant to any such clause, this clause (viii), the refinancing Indebtedness by its terms, or by the terms of any agreement or instrument pursuant to which such Indebtedness is issued, (x) does not provide for
payments of principal of such Indebtedness at stated maturity or by way of a sinking fund applicable thereto or by way of any mandatory redemption, defeasance, retirement or repurchase thereof by Level 3 or any Restricted Subsidiary (including
any redemption, retirement or repurchase which is contingent upon events or circumstances, but excluding any retirement required by virtue of the acceleration of any payment with respect to such Indebtedness upon any event of default thereunder), in
each case prior to the time the same are required by the terms of the Indebtedness being refinanced and (y) does not permit redemption or other retirement (including pursuant to an offer to purchase made by Level 3 or any Restricted
Subsidiary) of such Indebtedness at the option of the holder thereof prior to the time the same are required by the terms of the Indebtedness being refinanced, other than, in the case of clause (x) or (y), any such payment, redemption or
other retirement (including pursuant to an offer to purchase made by Level 3) which is conditioned upon a change of control pursuant to provisions substantially similar to those described under Section 2.05(d) or upon an asset sale
pursuant to provisions substantially similar to those described under Section 6.07(c);

Effective Date, such Guarantee is Incurred in accordance with (i) the last sentence of paragraph (d) of this Section 6.01 and (ii) Section 6.02. 
 (c) Notwithstanding any other provision of this Section 6.01, the maximum amount of Indebtedness that Level 3 or any Restricted Subsidiary may Incur pursuant to this Section 6.01 shall not be deemed to

sole discretion, shall classify, and may later reclassify, such item of Indebtedness in any manner that complies with this Section. To the extent permitted under applicable laws and regulations, in the event that any Restricted Subsidiary of
Level 3 Guarantees any of the Financing Inc. Notes, then Level 3 shall cause such Restricted Subsidiary to (i) become a Guarantor and a Loan Proceeds Note Guarantor, (ii) if such Restricted Subsidiary is a Borrower Restricted
Subsidiary, subordinate, in any bankruptcy, liquidation or winding up proceeding of such Borrower Restricted Subsidiary, such Borrower Restricted Subsidiary’s Guarantee of such Financing Inc. Notes to the Guarantee of the Obligations and the
Loan Proceeds Note Guarantee of such Borrower Restricted Subsidiary (or, in the case of Level 3 LLC, to the Loan Proceeds Note) and (iii) in the case of a Level 3 LLC Guarantee of the 2011 Floating Rate Notes, the 12.25% Notes, the 9.25% Notes,
the 8.75% Notes or the 2015 Floating Rate Notes, cause Level 3 LLC to enter into the Level 3 LLC 2011 Floating Rate Notes Supplemental Indenture, the Level 3 LLC 12.25% Notes Supplemental Indenture, the Level 3 LLC 9.25% Notes Supplemental
Indenture, the Level 3 LLC 8.75% Notes Supplemental Indenture or the Level 3 LLC 2015 Floating Rate Notes Supplemental Indenture, as the case may be. 
 SECTION 6.02. Limitation on Indebtedness of the Borrower and Borrower Restricted Subsidiaries. (a) The Borrower shall not, and shall not permit any Borrower Restricted Subsidiary to, directly or
indirectly, Incur any Indebtedness; provided, however, that (i) the Borrower or (ii) any Borrower Restricted Subsidiary may incur any Indebtedness if, after giving pro forma effect to such Incurrence and the receipt and
application of the net proceeds thereof, no Default or Event of Default would occur as a consequence of such Incurrence or be continuing following such Incurrence and the Borrower Debt Ratio would be less than (1) 4.0 to 1.0 if such
Indebtedness is Incurred on or prior to March 15, 2008 and (2) 3.75 to 1.0 if such Indebtedness is Incurred after March 15, 2008; provided, however, that any Borrower Restricted Subsidiary that Incurs Indebtedness

Section 6.01 in respect of Indebtedness previously Incurred pursuant to clause (ii) of paragraph (b) of Section 6.01, plus (D) the amount of all refinancing Indebtedness outstanding or available pursuant to clause
(vi) below in respect of Indebtedness previously Incurred pursuant to this clause (ii), at any one time not to exceed the greater of (x) $1,400,000,000 and (y) 1.5 times Pro Forma Consolidated Cash Flow Available for Fixed Charges of
the Borrower and the Borrower Restricted Subsidiaries for the four full fiscal quarters next preceding the Incurrence of such Indebtedness for which financial statements have been delivered pursuant to Section 5.01 or 5.02, as applicable, which
amount shall be permanently reduced by the amount of Net Available Proceeds used after the Effective Date to repay Indebtedness under any Credit Facilities (including the Loan Documents) or any refinancing Indebtedness in respect of any Credit
Facilities (including the Loan Documents) Incurred pursuant to clause (viii) of paragraph (b) of Section 6.01 or clause (vi) below), and not reinvested in Telecommunications/IS Assets or used to repay Indebtedness created under

Restricted Subsidiary or the Borrower of any Indebtedness so permitted to a Person other than the Borrower or another 
  

 70 








 Borrower Restricted Subsidiary or (y) if for any reason such Borrower Restricted Subsidiary ceases
to be a Borrower Restricted Subsidiary, the provisions of this clause (iv) shall no longer be applicable to such Indebtedness and such Indebtedness shall be deemed to have been Incurred by the borrower thereof at the time of such transfer,
conveyance or other disposition or when such Borrower Restricted Subsidiary ceases to be a Borrower Restricted Subsidiary and (C) the payment obligation of (i) such Indebtedness (if clause (A) above applies) and (ii) all

Proceeds Note Guarantor pursuant to clause (A) above until such time and only so long as such Foreign Restricted Subsidiary Guarantees any other Indebtedness of Level 3 or any Domestic Restricted Subsidiary; 
 (v) Indebtedness Incurred by a Person (other than Level 3 or any Sister Restricted Subsidiary) prior to the time (A) such Person
became a Borrower Restricted Subsidiary, (B) such Person merges into or consolidates with a Borrower Restricted Subsidiary or (C) a Borrower Restricted Subsidiary merges into or consolidates with such Person (in a transaction in which such

any Indebtedness pursuant to this clause (v), the Borrower could Incur at least $1.00 of additional Indebtedness pursuant to paragraph (a) above computed using “5.0 to 1.0” rather than “4.0 to 1.0” or “3.75 to
1.0,” as the case may be, as it appears therein and such Person or the Borrower Restricted Subsidiary into which such Person merges or consolidates is a Guarantor and a Loan Proceeds Note Guarantor; 
 (vi) Indebtedness of the Borrower or any Borrower Restricted Subsidiary Incurred to renew, extend, refinance, defease, repay, prepay,
repurchase, redeem, retire, exchange or refund (each, a “refinancing”) Indebtedness of the Borrower or any Borrower Restricted Subsidiary Incurred pursuant to paragraph (a) above or clause (i), (ii), (iii), (v) or

 (d) For purposes of determining any particular amount of Indebtedness under this Section 6.02, Guarantees (other than Guarantees of Indebtedness of
Level 3 or any Sister Restricted Subsidiary that are not Guarantees of Indebtedness Incurred by Level 3 or any Sister Restricted Subsidiary pursuant to clause (ii) of paragraph (b) of Section 6.01), Liens or obligations with
respect to letters of credit supporting Indebtedness otherwise included in the determination of such particular amount shall not be included and shall not be treated as Indebtedness. For purposes of determining compliance with this

cause such Borrower Restricted Subsidiary to (i) become a Guarantor and a Loan Proceeds Note Guarantor, (ii) to subordinate, in any bankruptcy, liquidation or winding up proceeding of such Borrower Restricted Subsidiary, such Borrower
Restricted Subsidiary’s Guarantee of such Financing Inc. Notes to the Guarantee of the Obligations and the Loan Proceeds Note Guarantee of such Borrower Restricted Subsidiary (or, in the case of Level 3 LLC, to the Loan Proceeds Note) and
(iii) in the case of a Level 3 LLC 
  

 73 








 Guarantee of the 2011 Floating Rate Notes, the 12.25% Notes, the 9.25% Notes, the 8.75% Notes or the 2015 Floating Rate
Notes, cause Level 3 LLC to enter into the Level 3 LLC 2011 Floating Rate Notes Supplemental Indenture, the Level 3 LLC 12.25% Notes Supplemental Indenture, the Level 3 LLC 9.25% Notes Supplemental Indenture, the Level 3 LLC 8.75% Notes Supplemental
Indenture or the Level 3 LLC 2015 Floating Rate Notes Supplemental Indenture, as the case may be. 
 SECTION 6.03. Limitation on
Restricted Payments. (a) Level 3: 
 (i) shall not, and shall not permit any Restricted Subsidiary to, directly
or indirectly, declare or pay any dividend, or make any distribution, in respect of its Capital Stock or to the holders thereof, excluding any dividends or distributions which are made solely to Level 3 or a Restricted Subsidiary (and, if such
Restricted Subsidiary is not a Wholly Owned Subsidiary, to the other stockholders of such Restricted Subsidiary on a pro rata basis or on a basis that results in the receipt by Level 3 or a Restricted Subsidiary of dividends or distributions of
greater value than it would receive on a pro rata basis) or any dividends or distributions payable solely in shares of Capital Stock of Level 3 (other than Disqualified Stock) or in options, warrants or other rights to acquire Capital Stock of
Level 3 (other than Disqualified Stock); 
 (ii) shall not, and shall not permit any Restricted Subsidiary to, purchase,
redeem, or otherwise retire or acquire for value (x) any Capital Stock of Level 3 or any Restricted Subsidiary or (y) any options, warrants or rights to purchase or acquire shares of Capital Stock of Level 3 or any Restricted
Subsidiary or any securities convertible or exchangeable into shares of Capital Stock of Level 3 or any Restricted Subsidiary, except, in any such case, any such purchase, redemption or retirement or acquisition for value (A) paid to
Level 3 or a Restricted Subsidiary (or, in the case of any such purchase, redemption or other retirement or acquisition for value with respect to a Restricted Subsidiary that is not a Wholly Owned Subsidiary, to the other stockholders of such
Restricted Subsidiary on a pro rata basis or on a basis that results in the receipt by Level 3 or a Restricted Subsidiary of payments of greater value than it would receive on a pro rata basis) or (B) paid solely in shares of Capital Stock
(other than Disqualified Stock) of Level 3; 
 (iii) shall not make, or permit any Restricted Subsidiary to make, any
Investment (other than an Investment in Level 3 or a Restricted Subsidiary or a Permitted Investment) in any Person, including the Designation of any Restricted Subsidiary as an Unrestricted Subsidiary, or the Revocation of any such
Designation, according to Section 6.10; 
 (iv) shall not, and shall not permit any Restricted Subsidiary to, redeem,
defease, repurchase, retire or otherwise acquire or retire for value, prior to any scheduled maturity, repayment or sinking fund payment, Indebtedness of Level 3 which is subordinate in right of payment to the Guarantee by Level 3 of the
Obligations or Indebtedness of any Restricted Subsidiary which is subordinate in 
  

 74 








 right of payment to the Loans (in the case of the Borrower) or the Guarantee of the Obligations (in the
case of Restricted Subsidiaries other than the Borrower) by such Restricted Subsidiary (other than any redemption, defeasance, repurchase, retirement or other acquisition or retirement for value made in anticipation of and satisfying a scheduled
maturity, repayment or sinking fund obligation due within one year thereof); and 
 (v) shall not, and shall not permit any
Restricted Subsidiary to, issue, transfer, convey, sell or otherwise dispose of Capital Stock of any Restricted Subsidiary to a Person other than Level 3 or another Restricted Subsidiary if the result thereof is that such Restricted Subsidiary shall
cease to be a Restricted Subsidiary, in which event the amount of such “Restricted Payment” shall be the Fair Market Value of the remaining interest, if any, in such former Restricted Subsidiary held by Level 3 and the other Restricted
Subsidiaries (each of clauses (i) through (v) being a “Restricted Payment”) 
 if: 
 (1) an Event of Default, or an event that with the passing of time or the giving of notice, or both, would constitute an Event of Default,
shall have occurred and be continuing, or 
 (2) upon giving effect to such Restricted Payment, Level 3 could not Incur
at least $1.00 of additional Indebtedness pursuant to paragraph (a) of Section 6.01, or 
 (3) upon giving effect to
such Restricted Payment, the aggregate of all Restricted Payments made on or after Measurement Date, including Restricted Payments made pursuant to clause (A) or (B) of the proviso at the end of this sentence, and Permitted
Investments made on or after the Measurement Date pursuant to clause (i) or (j) of the definition thereof (the amount of any such Restricted Payment or Permitted Investment, if made other than in cash, to be based upon Fair Market Value)
exceeds the sum of: 
 (A) 50% of cumulative Consolidated Net Income of Level 3 and its Restricted Subsidiaries (or
subtracting, in the case that Consolidated Net Income of Level 3 and its Restricted Subsidiaries shall be negative, 100% of such negative amount) since the end of the last full fiscal quarter prior to the Measurement Date through the last day of the
last full fiscal quarter ending prior to the date of such Restricted Payment for which consolidated financial statements have been delivered pursuant to Section 5.01 or 5.02, as applicable, and 
 (B) plus, in the case of any Revocation made after the Measurement Date, an amount equal to the lesser of the portion 

 

 75 








 (proportionate to Level 3’s equity interest in the Subsidiary to which such Revocation
relates) of the Fair Market Value of the net assets of such Subsidiary at the time of Revocation and the amount of Investments previously made (and treated as a Restricted Payment) by Level 3 or any Restricted Subsidiary in such Subsidiary;

 provided, however, that Level 3 or a Restricted Subsidiary may, without regard to the limitations in
clause (3) but subject to clauses (1) and (2), make (A) Restricted Payments in an aggregate amount not to exceed the sum of $50,000,000 and the aggregate net cash proceeds received after the Measurement Date (i) as capital
contributions to Level 3, from the issuance (other than to a Subsidiary or an employee stock ownership plan or trust established by Level 3 or any such Subsidiary for the benefit of their employees) of Capital Stock (other than
Disqualified Stock) of Level 3, and (ii) from the issuance or sale of Indebtedness of Level 3 or any Restricted Subsidiary (other than to a Subsidiary, Level 3 or an employee stock ownership plan or trust established by
Level 3 or any such Subsidiary for the benefit of their employees) that after the Measurement Date has been converted into or exchanged for Capital Stock (other than Disqualified Stock) of Level 3 and (B) Investments in Persons
engaged in the Telecommunications/IS Business in an aggregate amount not to exceed the after-tax gain on the sale, after the Measurement Date, of Special Assets to the extent sold for cash, Cash Equivalents, Telecommunications/IS Assets or the
assumption of Indebtedness of Level 3 or any Restricted Subsidiary (other than Indebtedness that is subordinated to the Loans, the Loan Proceeds Note or any applicable Guarantee of the Obligations or Loan Proceeds Note Guarantee) and release of
Level 3 and all Restricted Subsidiaries from all liability on the Indebtedness assumed. The aggregate net cash proceeds referred to in the immediately preceding clauses (A)(i) and (A)(ii) shall not be utilized to make Restricted
Payments pursuant to such clauses to the extent such proceeds have been utilized to make Permitted Investments under clause (i) of the definition of “Permitted Investments.” 
 (b) Notwithstanding the foregoing limitation, 
 (i) Level 3 may pay any dividend on Capital Stock of any class of Level 3 within 60 days after the declaration thereof if,
on the date when the dividend was declared, Level 3 could have paid such dividend in accordance with the foregoing provisions; provided, however, that at the time of such payment of such dividend, no other Event of Default shall
have occurred and be continuing (or result therefrom); 
 (ii) Level 3 may repurchase any shares of its Common Stock or
options to acquire its Common Stock from Persons who were formerly directors, officers or employees of Level 3 or any of its Subsidiaries or other Affiliates in an amount not to exceed $3,000,000 in any 12-month period; 
  

 76 








 (iii) Level 3 and any Restricted Subsidiary may refinance any Indebtedness otherwise
permitted by clause (viii) of paragraph (b) of Section 6.01 or clause (vi) of paragraph (b) of Section 6.02; 
 (iv) Level 3 and any Restricted Subsidiary may retire or repurchase any Capital Stock of Level 3 or of any Restricted Subsidiary or any Subordinated Debt of Level 3 in exchange for, or out of the
proceeds of substantially concurrent sale (other than to a Subsidiary or an employee stock ownership plan or trust established by Level 3 or any such Subsidiary for the benefit of their employees) of, Capital Stock (other than Disqualified
Stock) of Level 3; provided, however, that the proceeds from any such exchange or sale of Capital Stock shall be excluded from any calculation pursuant to clause (A)(i) in the proviso at the end of
paragraph (a) above or pursuant to clause (b) of the definition of “Invested Capital”; and 
 (v) Level 3 may pay cash dividends in any amount not in excess of $50,000,000 in any 12-month period in respect of Preferred Stock of Level 3 (other than Disqualified Stock). 
 The Restricted Payments described in the foregoing clauses (i), (ii) and (v) shall be included in the calculation of Restricted Payments; the Restricted
Payments described in clauses (iii) and (iv) shall be excluded in the calculation of Restricted Payments. 
 (c) The Borrower may
not, and may not permit any Borrower Restricted Subsidiary to, pay any dividend or make any distribution in respect of shares of its Capital Stock held by Level 3 or a Sister Restricted Subsidiary (whether in cash, securities or other Property)
or any payment (whether in cash, securities or other Property) on account of the purchase, redemption, retirement, acquisition, cancellation or termination of any such shares of Capital Stock (all such dividends, distributions and payments being
referred to herein as “Level 3 Transfers”), other than (i) Level 3 Transfers at such times and in such amounts as shall be necessary to permit Level 3 to pay administrative expenses attributable to the operations
of its Restricted Subsidiaries, (ii) Level 3 Transfers at such times and in such amounts as are sufficient for Level 3 to make the timely payment of interest, premium (if any) and principal (whether at stated maturity, by way of a
sinking fund applicable thereto, by way of any mandatory redemption, defeasance, retirement or repurchase thereof, including upon the occurrence of designated events or circumstances or by virtue of acceleration upon an event of default, or by way
of redemption or retirement at the option of the holder of the Indebtedness of Level 3, including pursuant to offers to purchase) according to the terms of any Indebtedness of Level 3, (iii) Level 3 Transfers (A) to permit
Level 3 to satisfy its obligations in respect of stock option plans or other benefit plans for management or employees of Level 3 and its Subsidiaries, (B) to permit Level 3 to pay dividends on Preferred Stock of Level 3 in
an amount not to exceed the aggregate net cash proceeds received by Level 3 (1) after September 30, 1999, from the issuance of Capital Stock, and 
  


 77 








 (2) from the issuance or sale of Indebtedness of Level 3 or any Restricted Subsidiary that after

Level 3 and (iv) additional Level 3 Transfers after October 1, 2003 in an aggregate amount not to exceed $50,000,000 in the aggregate. 
 SECTION 6.04. Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. (a) Level 3 shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly,
create or otherwise cause or suffer to exist or become effective any consensual encumbrance or restriction (other than pursuant to law or regulation) on the ability of any Restricted Subsidiary (i) to pay dividends (in cash or otherwise) or
make any other distributions in respect of its Capital Stock owned by Level 3 or any other Restricted Subsidiary or pay any Indebtedness or other obligation owed to Level 3 or any other Restricted Subsidiary, (ii) to make loans or
advances to Level 3 or any other Restricted Subsidiary or (iii) to transfer any of its Property to Level 3 or any other Restricted Subsidiary. 
 (b) Notwithstanding the foregoing limitation, Level 3 may, and may permit any Restricted Subsidiary to, create or otherwise cause or suffer to exist 
 (i) any encumbrance or restriction in effect on the Measurement Date, 
 (ii) any encumbrance or restriction under the Loan Documents, and any customary (as conclusively determined in good faith by the Chief
Financial Officer of Level 3) encumbrance or restriction applicable to a Restricted Subsidiary that is contained in an agreement or instrument governing or relating to Indebtedness contained in any Qualified Receivable Facility or Purchase
Money Debt Incurred pursuant to clause (ii) of paragraph (b) under Section 6.01 or clause (ii) of paragraph (b) under Section 6.02 (or refinancing Indebtedness thereof Incurred pursuant to
clause (viii) of paragraph (b) under Section 6.01 or clause (vi) of paragraph (b) under Section 6.02); provided, however, that such encumbrances and restrictions do not limit the ability of such Restricted
Subsidiary, directly or indirectly (including through another Subsidiary of the Borrower) (i) to pay dividends (in cash or otherwise) or make any other distributions in respect of its Capital Stock owned by the Borrower or any other Borrower
Restricted Subsidiary or pay any Indebtedness or other obligation owed to the Borrower, (ii) to make loans or advances to the Borrower or (iii) to transfer any of its Property (other than in the case of Purchase Money Debt, the
Telecommunications/IS Assets installed, constructed, acquired, leased, developed or improved with the proceeds of such Purchase Money Debt and any improvements or accessions thereto) to the Borrower, 
 (iii) any encumbrance or restriction pursuant to an agreement relating to any Acquired Debt, which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any Person, other than the Person so acquired, 
  

 78 








 (iv) any encumbrance or restriction pursuant to an agreement effecting a refinancing of
Indebtedness Incurred pursuant to an agreement referred to in clause (i), (ii) or (iii) of this paragraph (b); provided, however, that the provisions contained in such agreement relating to such encumbrance or
restriction are no more restrictive (as so determined) in any material respect than the provisions contained in the agreement the subject thereof, 
 (v) in the case of clause (iii) of paragraph (a) above, any encumbrance or restriction contained in any security agreement (including a Capital Lease Obligation) securing Indebtedness of
Level 3 or a Restricted Subsidiary otherwise permitted under this Agreement, but only to the extent such restrictions restrict the transfer of the Property subject to such security agreement, 
 (vi) in the case of clause (iii) of paragraph (a) above, customary provisions (A) that restrict the subletting,
assignment or transfer of any Property that is a lease, license, conveyance or similar contract, (B) contained in asset sale or other asset disposition agreements limiting the transfer of the Property being sold or disposed of pending the
closing of such sale or disposition or (C) arising or agreed to in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of Property of Level 3 or any
Restricted Subsidiary in any manner material to Level 3 or any Restricted Subsidiary, 
 (vii) any encumbrance or
restriction with respect to a Restricted Subsidiary imposed pursuant to an agreement which has been entered into for the sale or disposition of all or substantially all of the Capital Stock or Property of such Restricted Subsidiary; provided,
however, that the consummation of such transaction would not result in a Default or an Event of Default, that such restriction terminates if such transaction is abandoned and that the consummation or abandonment of such transaction occurs
within one year of the date such agreement was entered into, and 
 (viii) any encumbrance or restriction pursuant to this
Agreement. 
 SECTION 6.05. Limitation on Liens. Level 3 shall not, and shall not permit any Restricted Subsidiary to, directly or
indirectly, Incur or suffer to exist any Lien on or with respect to any Property now owned or acquired after the date hereof to secure any Indebtedness other than: 
 (i) Liens existing on the Effective Date and securing Indebtedness outstanding on the Effective Date, which in any event shall not include
Liens securing the Parent Intercompany Note or the Existing Notes; 
  

 79 








 (ii) Liens Incurred on or after the Effective Date: 
 (1) pursuant to the Loan Documents to secure Indebtedness permitted to be Incurred pursuant to clause (ii) of paragraph
(b) under Section 6.01 or clause (ii) of paragraph (b) under Section 6.02 (or refinancing Indebtedness in respect thereof Incurred pursuant to clause (viii) of paragraph (b) under Section 6.01 or clause
(vi) of paragraph (b) under Section 6.02); 
 (2) on Receivables, collections thereof and accounts established
solely for the collection of such Receivables to secure Indebtedness under Qualified Receivables Facilities permitted to be Incurred pursuant to clause (ii) of paragraph (b) under Section 6.01 or clause (ii) of paragraph
(b) under Section 6.02 (or refinancing Indebtedness thereof Incurred pursuant to clause (viii) of paragraph (b) under Section 6.01 or clause (vi) of paragraph (b) under Section 6.02); 
 (3) on cash to secure reimbursement obligations in respect of letters of credit permitted to be Incurred pursuant to clause (ii) of

(viii) of paragraph (b) under Section 6.01), provided that the amount of such cash does not exceed 110% of the face amount of such letters of credit; and 
 (4) on Property acquired after the Effective Date with the proceeds of Purchase Money Debt Incurred pursuant to clause (ii) of
paragraph (b) under Section 6.01 or clause (ii) of paragraph (b) under Section 6.02 (or refinancing Indebtedness thereof Incurred pursuant to clause (vi) of paragraph (b) under Section 6.02 or clause
(viii) of paragraph (b) under Section 6.01) to secure such Purchase Money Debt, provided that any such Lien may not extend to any Property other than the Telecommunications/IS Assets installed, constructed, acquired, leased,
developed or improved with the proceeds of such Purchase Money Debt and any improvements or accessions thereto (it being understood that all Indebtedness to any single lender or group of related lenders or outstanding under any single credit
facility, and in any case relating to the same group or collection of Telecommunications/IS Assets financed thereby, shall be considered a single Purchase Money Debt, whether drawn at one time or from time to time); 
 (iii) Liens in favor of Level 3 or any Restricted Subsidiary; provided, however, that any subsequent issue or transfer of
Capital Stock or other event that results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of the Indebtedness secured by any such Lien (except to Level 3 or a Restricted Subsidiary) shall be
deemed, in each case, to constitute the Incurrence of such Lien by the borrower thereof; 
  

 80 








 (iv) Liens outstanding on the Effective Date securing Purchase Money Debt and Liens on
Property acquired after the Effective Date with the proceeds of Purchase Money Debt Incurred pursuant to clause (iii) of paragraph (b) under Section 6.01 to secure such Purchase Money Debt, provided that any such Lien
may not extend to any Property other than the Telecommunications/IS Assets installed, constructed, acquired, leased, developed or improved with the proceeds of such Purchase Money Debt and any improvements or accessions thereto (it being understood
that all Indebtedness to any single lender or group of related lenders or outstanding under any single credit facility, and in any case relating to the same group or collection of Telecommunications/IS Assets financed thereby, shall be considered a
single Purchase Money Debt, whether drawn at one time or from time to time); 
 (v) Liens to secure Acquired Debt,
provided that (a) such Lien attaches to the acquired Property prior to the time of the acquisition of such Property and (b) such Lien does not extend to or cover any other Property; 
 (vi) Liens to secure Indebtedness Incurred to refinance, in whole or in part, Indebtedness secured by any Lien referred to in the
foregoing clauses (i), (iv) and (v) or this clause (vi) so long as such Lien does not extend to any other Property (other than improvements and accessions to the original Property) and the principal amount of Indebtedness so secured
is not increased except as otherwise permitted under clause (viii) of paragraph (b) of Section 6.01 or clause (vi) of paragraph (b) of Section 6.02; 
 (vii) Liens on Property (A) not constituting Collateral and (B) not required to become Collateral following the satisfaction of
the Guarantee Permit Condition and the Collateral Permit Condition, Incurred on or after the Measurement Date not otherwise permitted by the foregoing clauses (i) through (v) (but including in the computations of Liens permitted under this
clause (vii) Liens existing on the Effective Date which remain existing at the time of computation which are otherwise permitted under clause (i)) securing Indebtedness of Level 3 or any Restricted Subsidiary (other than the Borrower
or any Borrower Restricted Subsidiary) in an aggregate amount not to exceed 5% of Level 3’s Consolidated Tangible Assets. 
 (viii) Liens on Property of any Non-Telecommunications Subsidiary; provided, however, that the Incurrence of such Lien does not require the Person Incurring such Lien to secure any Indebtedness of any Person other than a
Non-Telecommunications Subsidiary; 
 (ix) Liens to secure Indebtedness Incurred pursuant to clause (viii) of
paragraph (b) of Section 6.02; and

 81 








 SECTION 6.06. Limitation on Sale and Leaseback Transactions. Level 3 shall not, and shall not
permit any Restricted Subsidiary to, directly or indirectly, enter into, assume, Guarantee or otherwise become liable with respect to any Sale and Leaseback Transaction, unless (i) Level 3 or such Restricted Subsidiary would be entitled to
Incur (a) Indebtedness in an amount equal to the Attributable Value of the Sale and Leaseback Transaction pursuant to Section 6.01 or Section 6.02 and (b) a Lien pursuant to Section 6.05, equal in amount to the Attributable
Value of the Sale and Leaseback Transaction, and (ii) the Sale and Leaseback Transaction is treated as an Asset Disposition and all of the conditions of Section 6.07 (including the provisions concerning the application of Net Available
Proceeds) are satisfied with respect to such Sale and Leaseback Transaction, treating all of the consideration received in such Sale and Leaseback Transaction as Net Available Proceeds for purposes of such Section 6.07. 
 SECTION 6.07. Limitation on Asset Dispositions. (a) Level 3 shall not, and shall not permit any Restricted Subsidiary to, make any Asset
Disposition unless: (i) Level 3 or the Restricted Subsidiary, as the case may be, receives consideration for such disposition at least equal to the Fair Market Value for the Property sold or disposed of as determined by the Board of
Directors of Level 3 in good faith and evidenced by a Board Resolution of Level 3; and (ii) at least 75% of the consideration for such disposition consists of cash or Cash Equivalents or the assumption of Indebtedness of the Borrower
or any Borrower Restricted Subsidiary (other than Indebtedness of the Borrower that is subordinated to the Obligations or Indebtedness of any Borrower Restricted Subsidiary that is subordinated to the Obligations of such Borrower Restricted
Subsidiary) and release of the Borrower and all Borrower Restricted Subsidiaries from all liability on the Indebtedness assumed (or if less than 75%, the remainder of such consideration consists of Telecommunications/IS Assets); provided,
however, that, to the extent such disposition involves Special Assets, all or any portion of the consideration may, at Level 3’s election, consist of Property other than cash, Cash Equivalents or the assumption of Indebtedness or
Telecommunications/IS Assets. 
 (b) If the Net Available Proceeds from any Asset Disposition (or any series of related Asset Dispositions)
consisting of Property that is Collateral or Property that would be required to become Collateral following the satisfaction of the Guarantee Permit Condition and the Collateral Permit Condition exceed $20,000,000, the Borrower shall deposit an
amount in cash or cash equivalents equal to such Net Available Proceeds (which such amount shall thereafter constitute the Net Available Proceeds of such Asset Disposition or related Asset Dispositions) into a deposit account in which the Collateral
Agent has a perfected security interest in favor of the Lenders. Prior to the time a Notice of Default shall have been delivered to the Borrower pursuant to Article VII, the Borrower may withdraw such Net Available Proceeds, and the Collateral
Agent, at the Request of the Borrower, shall take all actions necessary, at the expense of the Borrower, to promptly release the security interest in such Net Available Proceeds (i) to permit Level 3 or a Restricted Subsidiary to reinvest
such Net Available Proceeds in Telecommunications/IS Assets, (ii) to permit the Borrower to repay the Loans in accordance with Section 2.05(b) or (iii) following any prepayment of the Loans as required by Section 2.05(b), with
respect to any such Net Available Proceeds that have been rejected by Declining Lenders pursuant to Section 2.05(e), to Level 3 or any Restricted Subsidiary for any purpose. 
  

 82 








 (c) The Net Available Proceeds (or any portion thereof) from Asset Dispositions may be applied by
Level 3 or a Restricted Subsidiary, to the extent Level 3 or such Restricted Subsidiary elects: (1) to permanently prepay Borrowings in accordance with Section 2.05(b) or (c) or (2) to reinvest in Telecommunications/IS
Assets (including by means of an Investment in Telecommunications/IS Assets by a Restricted Subsidiary with Net Available Proceeds received by Level 3 or another Restricted Subsidiary). Level 3 shall not, and shall not permit any
Restricted Subsidiary, to acquire any Telecommunications/IS Assets with the Net Available Proceeds of any Asset Disposition consisting of Collateral or Property that would be required to become Collateral following the satisfaction of the Guarantee
Permit Condition and the Collateral Permit Condition unless such Telecommunications/IS Assets are Collateral or Property that would be required to become Collateral following the satisfaction of the Guarantee Permit Condition and the Collateral
Permit Condition. Any Net Available Proceeds from an Asset Disposition not applied in accordance with paragraph (b) within 330 days (or, in the case of a disposition of Special Assets identified in clause (a) of the definition thereof in
which the Net Available Proceeds exceed $500,000,000, 510 days) from the date of the receipt of such Net Available Proceeds shall constitute “Excess Proceeds.” The Borrower shall apply such Excess Proceeds to the extent and in
the manner required by Section 2.05. 
 (d) (1) The Borrower shall not, and shall not permit any Borrower Restricted Subsidiary, to
sell, transfer, lease or otherwise dispose of any Property that is Collateral or that would be required to become Collateral following the satisfaction of the Collateral Permit Condition to a Subsidiary of Level 3 (other than a Subsidiary that
is a Guarantor and a Grantor or that will become a Guarantor and a Grantor following satisfaction of the Guarantee Permit Condition and the Collateral Permit Condition), and (2) Level 3 shall not designate as an Unrestricted Subsidiary any
Borrower Restricted Subsidiary that owns, directly or indirectly, any Property that is Collateral or that would be required to become Collateral following the satisfaction of the Collateral Permit Condition unless either: 
 (A) (1) in the case of a sale, transfer, lease or other disposition, the Borrower or such Borrower Restricted Subsidiary receives
consideration for such sale, transfer, lease or other disposition at least equal to the Fair Market Value of such Property (which, in the case of the Offering Proceeds Notes, any other intercompany Indebtedness or the Loan Proceeds Note, is the
principal amount of such Offering Proceeds Note, such Indebtedness or the Loan Proceeds Note, as applicable, and any accrued and unpaid interest thereon), and 
 (2) in the case of a sale, transfer, lease or other disposition, the consideration consists of 100% in cash or Cash Equivalents; or

  

 83 








 (B) such transaction: 
 (1) is desirable in the conduct of the business of Level 3 and its Subsidiaries taken as a whole (as conclusively determined by the
Board of Directors of Level 3), and 
 (2) (i) in the case of a sale, transfer, lease or other disposition in which the
consideration does not consist of 100% cash or Cash Equivalents, the Fair Market Value of the Property that is Collateral so sold, transferred, leased or disposed of (net of any cash or Cash Equivalents received by the Borrower or such Borrower
Restricted Subsidiary in respect of such Collateral), or (ii) in the case of a designation of a Borrower Restricted Subsidiary as an Unrestricted Subsidiary, the Fair Market Value of all Property that is Collateral owned, directly or
indirectly, by such Borrower Restricted Subsidiary at the time it is designated an Unrestricted Subsidiary, when taken together with the Collateral Release Amount (determined prior to such sale, lease, transfer or other disposition or designation as
an Unrestricted Subsidiary), does not exceed 5.0% of Consolidated Tangible Assets as determined at the time of such sale, lease, transfer or other disposition or designation as an Unrestricted Subsidiary, on the basis of the most recent consolidated
balance sheet available to Level 3 (as conclusively determined in good faith by the Chief Financial Officer of Level 3). 
 For purposes of this
Section 6.07(d), “Collateral Release Amount” means an amount equal to: 
 (1) the sum of (x) the
Fair Market Value of any Property that constituted Collateral previously sold, transferred, leased or otherwise disposed of pursuant to this Section 6.07(d) for consideration not consisting of 100% cash or Cash Equivalents (net of any cash or
Cash Equivalents received by the transferor in consideration for such sale, transfer, lease or other disposition) plus (y) the Fair Market Value of all Property that constituted Collateral held directly or indirectly by each Borrower
Restricted Subsidiary previously designated as an Unrestricted Subsidiary pursuant to this Section 6.07(d), minus 
 (2) the sum of, without duplication, (x) the amount of any cash or Cash Equivalents received by the Borrower or a Borrower Restricted Subsidiary in repayment of principal or as a return of capital from an Investment made pursuant to
clause (B) of this Section 6.07(d) plus (y) the amount of any cash or Cash Equivalents received by the Borrower or a Borrower Restricted Subsidiary from a Borrower Restricted Subsidiary designated as an Unrestricted Subsidiary
pursuant to this Section 6.07(d) representing a return of capital, in the case of clauses (x) and (y), to the extent such cash or Cash Equivalents were treated as Net Available Proceeds from an Asset Disposition, plus (z) the Fair
Market Value 
  

 84 








 (determined at the time that such Property again becomes Collateral in accordance with the Security
Documents) of any Property which had ceased to be Collateral pursuant to this Section 6.07(d) and thereafter became Collateral in accordance with the terms of the Security Documents. 
 In the event of (a) a transfer of Property that constitutes Collateral made in accordance with this Section 6.07(d), such Property shall be
released from any Lien to which it is subject pursuant to the Security Documents in accordance with the procedures in Section 9.14 or (b) the designation of a Restricted Subsidiary as an Unrestricted Subsidiary in compliance with this
Section 6.07(d), such Restricted Subsidiary shall, by delivery of documentation providing for such release in form satisfactory to the Administrative Agent, be released from any Guarantee (in the case of a Guarantor) and its obligations under
the Collateral Agreement (in the case of a Grantor) previously made by such Subsidiary. 
 (e) The Borrower shall not, and shall not permit
any Borrower Restricted Subsidiary to, sell, transfer, lease or otherwise dispose of any Property that does not constitute Collateral to Level 3 or any Sister Restricted Subsidiary unless (i) the Borrower or such Borrower Restricted
Subsidiary receives consideration for such sale, transfer, lease or other disposition at least equal to the Fair Market Value of such Property and (ii) the consideration consists of either (A) 100% in cash or Cash Equivalents or
(B) Indebtedness of Level 3 or the Restricted Subsidiary to which Property was transferred that is secured by a Lien on such transferred Property. Level 3 or the Restricted Subsidiary to which Property was transferred for consideration
consisting of Indebtedness that is secured by a Lien on such Property in accordance with clause (ii)(B) of the prior sentence may substitute the Lien on such Property with a Lien on other Property (including any Property owned by the Borrower or a
Borrower Restricted Subsidiary) that, as determined by the Board of Directors of Level 3 in good faith and evidenced by a Board Resolution of Level 3 filed with the Agent upon request of the Agent, has a Fair Market Value of no less than the Fair
Market Value of the Property for which the substitution is made at the time of the substitution. The provisions of this paragraph do not apply to (a) dividends and distributions, (b) loans or advances and (c) purchases of services or
goods. 
 SECTION 6.08. Limitation on Issuance and Sales of Capital Stock of Restricted Subsidiaries. Level 3 shall at all times
own all the issued and outstanding Capital Stock of the Borrower. The Borrower shall at all times own all the issued and outstanding Capital Stock of Level 3 LLC. Level 3 shall not, and shall not permit any Restricted Subsidiary to, issue,
transfer, convey, sell or otherwise dispose of any shares of Capital Stock of a Restricted Subsidiary or securities convertible or exchangeable into, or options, warrants, rights or any other interest with respect to, Capital Stock of a Restricted
Subsidiary to any Person other than Level 3 or a Restricted Subsidiary except (i) a sale of all of the Capital Stock of such Restricted Subsidiary owned by Level 3 and any Restricted Subsidiary that complies with the provisions of
Section 6.07 to the extent such provisions apply, (ii) in a transaction that results in such Restricted Subsidiary becoming a Joint Venture, provided (x) such transaction complies with the provisions of 
  

 85 








 Section 6.07 to the extent such provisions apply and (y) the remaining interest of Level 3 or any other
Restricted Subsidiary in such Joint Venture would have been permitted as a new Restricted Payment or Permitted Investment under the provisions of Section 6.03, (iii) the issuance, transfer, conveyance, sale or other disposition of shares
of such Restricted Subsidiary so long as after giving effect to such transaction such Restricted Subsidiary remains a Restricted Subsidiary and such transaction complies with the provisions of Section 6.07 to the extent such provisions apply,
(iv) the transfer, conveyance, sale or other disposition of shares required by applicable law or regulation, (v) if required, the issuance, transfer, conveyance, sale or other disposition of directors’ qualifying shares,
(vi) Disqualified Stock issued in exchange for, or upon conversion of, or the proceeds of the issuance of which are used to refinance, shares of Disqualified Stock of such Restricted Subsidiary, provided that the amounts of the
redemption obligations of such Disqualified Stock shall not exceed the amounts of the redemption obligations of, and such Disqualified Stock shall have redemption obligations no earlier than those required by, the Disqualified Stock being exchanged,
converted or refinanced, (vii) in a transaction where Level 3 or a Restricted Subsidiary acquires at the same time not less than its Proportionate Interest in such issuance of Capital Stock, (viii) Capital Stock issued and outstanding
on the Measurement Date, (ix) Capital Stock of a Restricted Subsidiary issued and outstanding prior to the time that such Person becomes a Restricted Subsidiary so long as such Capital Stock was not issued in contemplation of such Person’s
becoming a Restricted Subsidiary or otherwise being acquired by Level 3 and (x) an issuance of Preferred Stock of a Restricted Subsidiary (other than Preferred Stock convertible or exchangeable into Common Stock of any Restricted
Subsidiary) otherwise permitted by this Agreement. In the event of (a) the consummation of a transaction referred to in any of the foregoing clauses that results in a Restricted Subsidiary that is a Guarantor or a Grantor (or both) no longer
being a Restricted Subsidiary and (b) the execution and delivery of documentation providing for such release in form satisfactory to the Administrative Agent, any such Guarantor or Grantor (or Guarantor and Grantor) shall be released from all
its obligations under its Guarantee (in the case of a Guarantor) and its obligations under the Collateral Agreement (in the case of a Grantor). 
 SECTION 6.09. Transactions with Affiliates. Level 3 shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, sell, lease, transfer, or otherwise dispose of any of its Property to, or purchase any
Property from, or enter into any contract, agreement, understanding, loan, advance, Guarantee or transaction (including the rendering of services) with or for the benefit of, any Affiliate (each of the foregoing, an “Affiliate
Transaction”), unless (a) such Affiliate Transaction or series of Affiliate Transactions is (i) in the best interest of Level 3 or such Restricted Subsidiary and (ii) on terms that are no less favorable to Level 3 or such
Restricted Subsidiary than those that would have been obtained in a comparable arm’s-length transaction by Level 3 or such Restricted Subsidiary with a Person that is not an Affiliate (or, in the event that there are no comparable transactions
involving Persons who are not Affiliates of Level 3 or the relevant Restricted Subsidiary to apply for comparative purposes, is otherwise on terms that, taken as a whole, Level 3 has determined to be fair to Level 3 or the relevant Restricted
Subsidiary) and (b) Level 3 obtains (i) with respect to any Affiliate Transaction or series of Affiliate Transactions involving aggregate payments in excess of $10,000,000 but less than $15,000,000, a certificate of the chief executive,
operating or 
  

 86 








 financial officer of Level 3 evidencing such officer’s determination that such Affiliate Transaction or series
of Affiliate Transactions complies with clause (a) above and (ii) with respect to any Affiliate Transaction or series of Affiliate Transactions involving aggregate payments equal to or in excess of $15,000,000, a Board Resolution of
Level 3 certifying that such Affiliate Transaction or series of Affiliate Transactions complies with clause (a) above and that such Affiliate Transaction or series of Affiliate Transactions has been approved by the Board of Directors
of Level 3, including a majority of the disinterested members of the Board of Directors of Level 3; provided, however, that, in the event that there shall not be at least two disinterested members of the Board of Directors of
Level 3 with respect to the Affiliate Transaction, Level 3 shall, at the request of the Administrative Agent, in addition to such Board Resolution, deliver to the Administrative Agent a written opinion from an investment banking firm of
national standing in the United States which, in the good faith judgment of the Board of Directors of Level 3, is independent with respect to Level 3 and its Affiliates and qualified to perform such task, which opinion shall be to the
effect that the consideration to be paid or received in connection with such Affiliate Transaction is fair, from a financial point of view, to Level 3 or such Restricted Subsidiary. 
 Notwithstanding the foregoing, the following shall not be deemed Affiliate Transactions: (i) any employment agreement entered into by Level 3
or any of its Restricted Subsidiaries in the ordinary course of business and consistent with industry practice; (ii) any agreement or arrangement with respect to the compensation of a director or officer of Level 3 or any Restricted
Subsidiary approved by a majority of the disinterested members of the Board of Directors of Level 3 and consistent with industry practice; (iii) transactions between or among Level 3 and its Restricted Subsidiaries; provided,
however, that no more than 5% of the Voting Stock (on a fully diluted basis) of any such Restricted Subsidiary is owned by an Affiliate of Level 3 (other than a Restricted Subsidiary); (iv) Restricted Payments and Permitted
Investments permitted by Section 6.03 (other than Investments in Affiliates that are not Level 3 or Restricted Subsidiaries); (v) transactions pursuant to the terms of any agreement or arrangement as in effect on the Measurement Date;
and (vi) transactions with respect to wireline or wireless transmission capacity, the lease or sharing or other use of cable or fiber optic lines, equipment, rights-of-way or other access rights, between Level 3 (or any Restricted
Subsidiary) and any other Person; provided, however, that, in the case of this clause (vi), such transaction complies with clause (a) in the immediately preceding paragraph. 
 SECTION 6.10. Limitation on Designations of Unrestricted Subsidiaries. Level 3 shall not designate (1) the Borrower or Level 3
LLC as an Unrestricted Subsidiary or (2) any other Subsidiary (other than a newly created Subsidiary in which no Investment has previously been made) as an “Unrestricted Subsidiary” under this Agreement (a
“Designation”) unless in the case of this clause (2): 
 (a) no Default or Event of Default shall have
occurred and be continuing at the time of or after giving effect to such Designation; 
 (b) immediately after giving effect
to such Designation, Level 3 would be able to Incur $1.00 of Indebtedness under paragraph (a) of Section 6.01; and 
  

 87 








 (c) Level 3 would not be prohibited under any provision of this Agreement from
making an Investment at the time of Designation (assuming the effectiveness of such Designation) in an amount (the “Designation Amount”) equal to the portion (proportionate to Level 3’s equity interest in such Restricted
Subsidiary) of the Fair Market Value of the net assets of such Restricted Subsidiary on such date. 
 In the event of any such Designation, Level 3
shall be deemed to have made an Investment constituting a Restricted Payment pursuant to Section 6.03 for all purposes of this Agreement in the Designation Amount; provided, however, that, upon a Revocation of any such Designation
of a Subsidiary, Level 3 shall be deemed to continue to have a permanent “Investment” in an Unrestricted Subsidiary of an amount (if positive) equal to (i) Level 3’s “Investment” in such Subsidiary at the time
of such Revocation less (ii) the portion (proportionate to Level 3’s equity interest in such Subsidiary) of the Fair Market Value of the net assets of such Subsidiary at the time of such Revocation. At the time of any Designation of
any Subsidiary as an Unrestricted Subsidiary, such Subsidiary shall not own any Capital Stock of Level 3 or any Restricted Subsidiary. In addition, neither Level 3 nor any Restricted Subsidiary shall at any time (x) provide credit
support for, or a Guarantee of, any Indebtedness of any Unrestricted Subsidiary (including any undertaking, agreement or instrument evidencing such Indebtedness); provided, however, that Level 3 or a Restricted Subsidiary may
pledge Capital Stock or Indebtedness of any Unrestricted Subsidiary on a nonrecourse basis such that the pledgee has no claim whatsoever against Level 3 other than to obtain such pledged Capital Stock or Indebtedness, (y) be directly or
indirectly liable for any Indebtedness of any Unrestricted Subsidiary or (z) be directly or indirectly liable for any Indebtedness which provides that the holder thereof may (upon notice, lapse of time or both) declare a default thereon or
cause the payment thereof to be accelerated or payable prior to its final scheduled maturity upon the occurrence of a default with respect to any Indebtedness, Lien or other obligation of any Unrestricted Subsidiary (including any right to take
enforcement action against such Unrestricted Subsidiary), except in the case of clause (x) or (y) to the extent permitted under Sections 6.03 and 6.09. 
 Unless Designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of Level 3 will be classified as a Restricted Subsidiary;
provided, however, that such Subsidiary shall not be designated as a Restricted Subsidiary and shall be automatically classified as an Unrestricted Subsidiary if either of the requirements set forth in clauses (a) and (b) of
the immediately following paragraph will not be satisfied immediately following such classification. Except as provided in the first sentence of this Section 6.10, no Restricted Subsidiary may be redesignated as an Unrestricted Subsidiary.

 A Designation may be revoked (a “Revocation”) by a Board Resolution of Level 3 delivered to the Administrative
Agent, provided that Level 3 will not make any Revocation unless: 
 (a) no Default or Event of Default shall
have occurred and be continuing at the time of and after giving effect to such Revocation; and 
  

 88 








 (b) all Liens and Indebtedness of such Unrestricted Subsidiary outstanding
immediately following such Revocation would, if Incurred at such time, have been permitted to be Incurred at such time for all purposes of this Agreement. 
 All Designations and Revocations must be evidenced by Board Resolutions of Level 3 delivered to the Administrative Agent (i) certifying compliance with the foregoing provisions and (ii) giving the effective date of such
Designation or Revocation. Upon Designation of a Restricted Subsidiary as an Unrestricted Subsidiary in compliance with this Section 6.10, such Restricted Subsidiary shall, by delivery of documentation providing for such release in form
satisfactory to the Administrative Agent, be released from any Guarantee (in the case of a Guarantor) and its obligations under the Collateral Agreement (in the case of a Grantor) previously made by such Subsidiary. 
 SECTION 6.11. Limitation on Actions with respect to Existing Intercompany Obligations. Without the consent of the holders of at least two-thirds
of the outstanding principal amount of the Loans: 
 (a) the Borrower shall not forgive or waive or fail to enforce any of its
rights under any Offering Proceeds Note, the Loan Proceeds Note, any Financing Inc. Notes Supplemental Indenture, the Omnibus Offering Proceeds Note Subordination Agreement or any other agreement with Level 3 or any Restricted Subsidiary to
subordinate a payment obligation on any Indebtedness to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note, a Loan Proceeds Note Guarantee, any Offering Proceeds Note or any Offering Proceeds Note Guarantee,
and the Borrower and Level 3 LLC may not amend the Loan Proceeds Note, a Loan Proceeds Note Guarantee, any Offering Proceeds Note or any Offering Proceeds Note Guarantee, in a manner adverse to the Lenders; provided, however, that
that in the event of an Event of Default of Level 3 LLC as described in clause (i) or (j) of Article VII, the principal then outstanding together with accrued interest thereon on the Loan Proceeds Note, each Offering Proceeds Note, the
Loan Proceeds Note Guarantee and each Offering Proceeds Note Guarantee shall automatically become due and payable without presentment, demand, protest or other notice of any kind; 
 (b) in the event Level 3 LLC (or any successor obligor under the Loan Proceeds Note) repays all or a portion of the Loan Proceeds Note,
the Borrower must prepay the Loans in a principal amount equal to the principal amount of the Loan Proceeds Note then repaid in accordance with, and if at such time permitted by, this Agreement; provided, however, that if at any time
the principal amount of the Loan Proceeds Note is greater than the principal amount of the Loans that remains outstanding, Level 3 LLC (or any successor obligor under the Loan Proceeds Note) may repay or forgive or waive an amount of the Loan
Proceeds Note equal to such excess without complying with this paragraph (b); 
 (c) Level 3 shall not, and shall not permit
any Restricted Subsidiary to, provide any Lien on its Property for the benefit of, or any Guarantee (other than a similarly subordinated Guarantee) or other form of credit enhancement in respect 
  

 89 








 of, (i) the Parent Intercompany Note or (ii) any other intercompany note required by
clause (vi) of paragraph (b) of Section 6.01 or clause (iv) of paragraph (b) of Section 6.02 to be subordinated to the prior payment in full in cash of all obligations with respect to the Loan
Proceeds Note or a Loan Proceeds Note Guarantee, or take any other action with the purpose or effect of making the Parent Intercompany Note senior to or equal in right of payment with any Offering Proceeds Note or the Loan Proceeds Note;

 (d) Level 3 shall not, and shall not permit any Restricted Subsidiary to, provide any Lien on its Property for the
benefit of, or any Guarantee (other than a similarly subordinated Guarantee) or other form of credit enhancement in respect of, (i) any Offering Proceeds Note or (ii) any other intercompany note required by clause (vi) of paragraph
(b) of Section 6.01 or clause (iv) of paragraph (b) of Section 6.02 to be subordinated to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note or a Loan Proceeds Note Guarantee, or take
any other action with the purpose or effect of making any Offering Proceeds Note senior to or equal in right of payment with the Loan Proceeds Note; 
 (e) Level 3 and Level 3 LLC shall not amend the terms of the Parent Intercompany Note or any Offering Proceeds Note in a manner adverse to the Lenders, the determination of which shall be made by the Board of
Directors of Level 3 acting in good faith and shall be evidenced by a Board Resolution of Level 3; 
 (f) Level 3, the
Borrower and Level 3 LLC shall not amend any of the Financing Inc. Notes Supplemental Indentures or the Omnibus Offering Proceeds Note Subordination Agreement in a manner adverse to the Lenders and Level 3 or any Restricted Subsidiary and the
Borrower shall not amend any other agreement between Level 3 or any Restricted Subsidiary and the Borrower to subordinate a payment obligation on any Indebtedness of Level 3 or any Restricted Subsidiary to the prior payment in full in cash of all
obligations with respect to the Loan Proceeds Note, in each case, the determination of which shall be made by the Board of Directors of Level 3 acting in good faith and shall be evidenced by a Board Resolution of Level 3; 
 (g) unless an Event of Default has occurred and is continuing, Level 3 shall neither cause nor permit the Borrower to demand
repayment of any Offering Proceeds Note prior to the satisfaction of the Guarantee Permit Condition and the Collateral Permit Condition; and 
 (h) Level 3 and the Borrower shall cause any Indebtedness of Level 3 LLC to Level 3 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 3 Business Days of the Incurrence of such Indebtedness. 
  

 90 








 SECTION 6.12. Covenant Suspension. During any period of time (a “Suspension
Period”) that (i) the ratings assigned to the Term Loan by both of the Rating Agencies are Investment Grade Ratings and (ii) no Default or Event of Default has occurred and is continuing, Level 3 and the Restricted Subsidiaries
will not be subject to the covenants set forth in Sections 6.01, 6.02, 6.03, 6.04, 6.06(i)(a), 6.07, 6.08 (other than the first two sentences thereof), 6.09, 6.13(a)(3) and (4), 6.13(c)(3) and (4) and clause (b) of the first sentence of
Section 6.10 (collectively, the “Suspended Covenants”). In the event that Level 3 and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the preceding sentence and, on
any subsequent date (the “Reversion Date”), one or both of the Rating Agencies withdraws its ratings or downgrades the ratings assigned to the Loan below the required Investment Grade Ratings or a Default or Event of Default occurs
and is continuing, then Level 3 and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants and calculations of the amount available to be made as Restricted Payments under Section 6.03 will be made as
though Section 6.03 had been in effect during the entire period of time from the Measurement Date. On the Reversion Date, all Indebtedness Incurred during the Suspension Period will be classified to have been Incurred pursuant to paragraph
(a) of Section 6.01 or one of the clauses set forth in paragraph (b) of Section 6.01 or paragraph (a) of Section 6.02 or one of the clauses set forth in paragraph (b) of Section 6.02 (in each case to the
extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to Indebtedness Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness
would not be permitted to be Incurred pursuant to paragraph (a) of Section 6.01 or one of the clauses set forth in paragraph (b) of Section 6.01 or paragraph (a) of Section 6.02 or one of the clauses set
forth in paragraph (b) of Section 6.02, such Indebtedness will be deemed to have been outstanding on the Measurement Date, so that it is classified as permitted under Section 6.01(b)(v) or Section 6.02(b)(iii). If the
Incurrence of any Indebtedness by a Restricted Subsidiary during the Suspension Period would have been prohibited or conditioned upon such Restricted Subsidiary entering into a Guarantee of the Obligations and a Loan Proceeds Note Guarantee had
Section 6.01 and Section 6.02 been in effect at the time of such Incurrence, such Restricted Subsidiary shall enter into a Guarantee of the Obligations and a Loan Proceeds Note Guarantee that are senior to or pari passu with such
Indebtedness within ten days after the Reversion Date. For purposes of determining compliance with Section 6.07 on the Reversion Date, the Net Available Proceeds from all Asset Dispositions not applied in accordance with the covenant will
be deemed to be reset to zero. Notwithstanding the foregoing, neither (a) the continued existence, after the date of such withdrawal or downgrade, of facts and circumstances or obligations that were Incurred or otherwise came into existence
during a Suspension Period nor (b) the performance of any such obligations, shall constitute a breach of any covenant set forth in the Agreement or cause a Default or Event of Default thereunder; provided, however, that
(1) Level 3 and its Restricted Subsidiaries did not Incur or otherwise cause such facts and circumstances or obligations to exist in anticipation of a withdrawal or downgrade below investment grade, (2) Level 3 reasonably
believed that such Incurrence or actions would not result in such a withdrawal or downgrade and (3) if so required each Restricted Subsidiary shall have entered into a Guarantee of the Obligations and a Loan Proceeds 
  

 91 








 Note Guarantee within the specified time period. For purposes of clauses (1) and (2) in the preceding
sentence, anticipation and reasonable belief may be determined by Level 3 and shall be conclusively evidenced by a board resolution to such effect adopted in good faith by the Board of Directors of Level 3. In reaching their determination, the
Board of Directors of Level 3 may, but need not, consult with the Rating Agencies. 
 SECTION 6.13. Consolidation, Merger, Conveyance,
Transfer or Lease. (a) Level 3 May Consolidate, etc., Only on Certain Terms. Level 3 shall not, in a single transaction or a series of related transactions, (i) consolidate with or merge into any other Person or
Persons or permit any other Person to consolidate with or merge into Level 3 or (ii) directly or indirectly, transfer, sell, lease, convey or otherwise dispose of all or substantially all its assets to any other Person or Persons unless:

 (1) in a transaction in which Level 3 is not the surviving Person or in which Level 3 transfers, sells, leases,
conveys or otherwise disposes of all or substantially all of its assets to any other Person, the resulting surviving or transferee Person (the “successor entity”) is organized under the laws of the United States of America or any State
thereof or the District of Columbia and shall expressly assume all of Level 3’s Obligations under the Loan Documents in a form satisfactory to the Administrative Agent; 
 (2) immediately before and after giving effect to such transaction and treating any Indebtedness which becomes an obligation of
Level 3 (or the successor entity) or a Restricted Subsidiary as a result of such transaction as having been Incurred by Level 3 or such Restricted Subsidiary at the time of the transaction, no Default or Event of Default shall have
occurred and be continuing; 
 (3) immediately after giving effect to such transaction and treating any Indebtedness which
becomes an obligation of Level 3 (or the successor entity) or a Restricted Subsidiary as a result of such transaction as having been Incurred by Level 3 or such Restricted Subsidiary at the time of the transaction, Level 3 (or the
successor entity) could Incur at least $1.00 of additional Indebtedness pursuant to paragraph (a) of Section 6.01; 
 (4) in the case of a transfer, sale, lease, conveyance or other disposition of all or substantially all of the assets of Level 3, such assets shall have been transferred as an entirety or virtually as an entirety to one Person and such
Person shall have complied with all the provisions of this paragraph; and 
 (5) Level 3 and the Borrower have delivered
to the Administrative Agent an Officers’ Certificate and Opinion of Counsel, each in form and substance reasonably satisfactory to the Administrative Agent, stating that such consolidation, merger, transfer, sale, lease, conveyance or other
disposition and the assumption by such Person of the Obligations under the Loan Documents, complies with this Section and that all conditions precedent herein have been complied with. 
  

 92 








 (b) Successor Level 3 Substituted. Upon any consolidation of Level 3 with or merger of
Level 3 with or into any other Person or any transfer, sale, lease, conveyance or other disposition of all or substantially all the assets of Level 3 to any Person or Persons in accordance with Section 6.13(a), the successor Person
formed by such consolidation or into which Level 3 is merged or to which such transfer, sale, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, Level 3 under
this Agreement with the same effect as if such successor Person had been named as Level 3 herein, and the predecessor Level 3 (which term shall for this purpose mean the Person named as “Level 3” in the first paragraph of
this Agreement or any successor Person which shall have become such in the manner described in Section 6.13(a)), except in the case of a lease, shall be released from all its obligations and covenants under this Agreement and the other Loan
Documents and may be dissolved and liquidated.

in a single transaction or a series of related transactions, (i) consolidate or merge into Level 3 or permit Level 3 to consolidate with or merge into the Borrower or (ii) except to the extent permitted under Section 6.03,
directly or indirectly, transfer, sell, lease, convey or otherwise dispose of all or substantially all its assets to Level 3. Additionally, the Borrower shall not, in a single transaction or a series of related transactions,
(i) consolidate with or merge into any other Person or Persons or permit any other Person to consolidate with or merge into the Borrower or (ii) (other than, to the extent permitted under Section 6.03, to a Restricted Subsidiary that
is or becomes a Guarantor and a Loan Proceeds Note Guarantor or to Level 3 so long as Level 3 is a Guarantor) directly or indirectly, transfer, sell, lease, convey or otherwise dispose of all or substantially all its assets to any other
Person or Persons, unless: 
 (1) in a transaction in which the Borrower is not the surviving Person or in which the Borrower
transfers, sells, leases, conveys or otherwise disposes of all or substantially all of its assets to any other Person, the successor entity is organized under the laws of the United States of America or any State thereof or the District of Columbia
and shall expressly assume all of the Borrower’s Obligations under the Loan and the Loan Documents in a form satisfactory to the Administrative Agent; 
 (2) immediately before and after giving effect to such transaction and treating any Indebtedness which becomes an obligation of the Borrower (or the successor entity) or a Borrower Restricted Subsidiary as a result of
such transaction as having been Incurred by the Borrower or such Borrower Restricted Subsidiary at the time of the transaction, no Default or Event of Default shall have occurred and be continuing; 
 (3) immediately after giving effect to such transaction, the Consolidated Net Worth of the Borrower (or the successor entity) is equal to
or greater than that of the Borrower immediately prior to the transaction; 
  

 93

the Borrower (or the successor entity) could Incur at least $1.00 of additional Indebtedness pursuant to paragraph (a) of Section 6.02; 
 (5) in the case of a transfer, sale, lease, conveyance or other disposition of all or substantially all of the assets of the Borrower, such assets shall have been transferred as an entirety or virtually as an entirety
to one Person and such Person shall have complied with all the provisions of this paragraph; and 
 (6) Level 3 and the
Borrower have delivered to the Administrative Agent an Officers’ Certificate and an Opinion of Counsel, each in form and substance reasonably satisfactory to the Administrative Agent, stating that such consolidation, merger, transfer, sale,
lease, conveyance or other disposition and the assumption by such Person of the Obligations under the Loan Documents complies with this Article and that all conditions precedent herein provided for relating to such transaction have been complied
with, and, with respect to such Officers’ Certificate, setting forth the manner of determination of the Consolidated Net Worth, in accordance with clause (3) of this subsection (c), of the Borrower or, if applicable, of the successor
entity as required pursuant to the foregoing. 
 (d) Successor Borrower Substituted. Upon any consolidation of the Borrower with or
merger of the Borrower with or into any other Person or any transfer, sale, lease, conveyance or other disposition of all or substantially all the assets of the Borrower to any Person or Persons in accordance with Section 6.13(c), the successor
Person formed by such consolidation or into which the Borrower is merged or to which such transfer, sale, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the

 (e) Guarantor (other than Level 3) May
Consolidate, etc., Only on Certain Terms. A Guarantor (other than Level 3) shall not, in a single transaction or a series of related transactions, (i) consolidate with or merge into any other Person or Persons (other than, with respect

Subsidiary or Level 3) or permit any other Person (other than, with respect to a Guarantor that is a Borrower Restricted Subsidiary, another Guarantor that is a Borrower 
  

 94 








 Restricted Subsidiary, and with respect to a Guarantor that is a Sister Restricted Subsidiary, Level 3 or another
Guarantor that is a Sister Restricted Subsidiary) to consolidate with or merge into such Guarantor or (ii) except to another Guarantor to the extent permitted under Section 6.03, directly or indirectly, transfer, sell, lease, convey or

 (2) either

into which such Guarantor is merged or to which such transfer, sale, lease, conveyance or other disposition is made (other than any such transaction made in accordance with Section 6.13(e)(2)(B)) shall succeed to, and be substituted for, and
may exercise every right and power of, such Guarantor under the Loan Documents with the same effect as if such successor Person had been named as a Guarantor herein, and the predecessor Guarantor (which term shall for this purpose mean the Person
named as the “Guarantor” in the first paragraph of the applicable supplement 
  

 95 








 to this Agreement or any successor Person which shall have become such in the manner described in subsection (e)),
except in the case of a lease, shall be released from all its Obligations and covenants under the Loan Documents and may be dissolved and liquidated. 
 (g) Loan Proceeds Note Guarantor May Consolidate, etc., Only on Certain Terms. A Loan Proceeds Note Guarantor shall not, in a single transaction or a series of related transactions, (i) consolidate with or

respect to an Loan Proceeds Note Guarantor that is a Sister Restricted Subsidiary, another Loan Proceeds Note Guarantor that is a Sister Restricted Subsidiary or Level 3) or permit any other Person (other than, with respect to an Loan Proceeds

Event of Default shall have occurred and be continuing; 
 (2) either (a) in a transaction in which such Loan Proceeds
Note Guarantor is not the surviving Person or in which such Loan Proceeds Note Guarantor transfers, sells, leases, conveys or otherwise disposes of all or substantially all of its assets to any other Person, the resulting surviving or transferee
Person is organized under the laws of the United States of America or any State thereof or the district of Columbia and shall expressly assume all of such Loan Proceed Note Guarantor’s obligations under the Loan Proceeds Note Guarantee and any
subordination agreement between the Borrower and such Loan Proceed Note Guarantor relating to the Loan Proceeds Note; or (b) such transaction complies with Section 6.07 (or Level 3 certifies in an Officers’ Certificate to the
Administrative Agent that it will comply with the requirements of such covenant relating to application of the proceeds of such transaction); and 
 (3) Level 3 and the Borrower have delivered to the Administrative Agent an Officers’ Certificate and an Opinion of Counsel, each in form and substance

 97

 then, and in every such event (other than an event with respect to the Borrower or Level 3 described in clause (i) or (j) of this Article), and at any
time thereafter during the continuance of such event, the Administrative Agent may, and at the request of the Required Lenders shall, by notice to the Borrower, take any or all of the following actions, at the same or different times: declare
the Loans then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be
due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which
are hereby waived by the Borrower and enforce, as Collateral Agent, all the rights and remedies under the Security Documents; and in case of any event with respect to Level 3 or the Borrower described in clause (i) or (j) of this
Article, the principal of the Loans then outstanding, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder, shall automatically become due and payable, without presentment, demand, protest or
other notice of any kind, all of which are hereby waived by the Borrower, and the Collateral Agent may, to the extent permitted by applicable law, exercise all rights and remedies under the Security Documents. 
 ARTICLE VIII 
 The Agent 
 Each of the Lenders hereby irrevocably appoints the Agent as its agent and authorizes the Agent to take such actions on its behalf and to exercise such
powers as are delegated to the Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto. 
 In the event the institution serving as the Agent hereunder shall also be a Lender, it shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were
not the Agent, and such institution and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with Level 3, the Borrower or any Subsidiary or Affiliate thereof as if it were not the Agent hereunder.

 The Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality
of the foregoing, (a) the Agent shall not be subject to any fiduciary or other implied duties, regardless of whether 
  

 99 








 a Default has occurred and is continuing, (b) the Agent shall not have any duty to take any discretionary action or
exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that the Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as
shall be necessary under the circumstances as provided in Section 9.02), and shall not have any duty to take any action or exercise any powers that would result in the incurrence by it of costs or expenses unless arrangements satisfactory to it
to ensure the prompt payment of all such costs or expenses shall have been made by the Lenders, and (c) except as expressly set forth in the Loan Documents, the Agent shall not have any duty to disclose, and shall not be liable for the failure
to disclose, any information relating to Level 3, the Borrower or any of the Subsidiaries of Level 3 that is communicated to or obtained by the institution serving as Agent or any of its Affiliates in any capacity. The Agent shall not be
liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the
absence of its own gross negligence or willful misconduct. The Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Agent by Level 3, the Borrower or a Lender, and the Agent shall
not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered
thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of
any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to
the Agent. As to any matters not expressly provided for by this Agreement and the other Loan Documents (including enforcement or collection), the Administrative Agent and the Collateral Agent shall not be required to exercise any discretion or take
any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Requisite Lenders, and such instructions shall be binding upon all Lenders,
provided, however, that the Administrative Agent and the Collateral Agent shall not be required to take any action that (i) the Administrative Agent or the Collateral Agent in good faith believes exposes it to personal liability
unless it receives an indemnification satisfactory to it from the Lenders with respect to such action or (ii) is contrary to this Agreement or applicable law. 
 The 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 Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Agent
may consult with legal counsel (who may be counsel for Level 3 or the Borrower), 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. 
  

 100 








 The Agent may perform any and all its duties and exercise its rights and powers by or through any one or
more sub-agents appointed by the Agent. The Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall
apply to any such sub-agent and to the Related Parties of each Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as
Agent. 
 Subject to the appointment and acceptance of a successor as provided in this paragraph, the Agent may resign at any time by
notifying the Lenders and Level 3. Upon any such resignation, the Required Lenders shall have the right, with, so long as no Default or Event of Default shall have occurred and be continuing, the consent of Level 3 (which consent shall not
be unreasonably withheld or delayed) to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation,
then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent which shall be a Lender or a bank with an office in New York, New York, or an Affiliate of such Lender or any such bank. Upon the acceptance of its appointment as Agent
hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees
payable by Level 3 and the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed with such successor. After the Agent’s resignation hereunder, the provisions of this Article and
Section 9.03 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Agent. 
 Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or related agreement or any document furnished hereunder or
thereunder.

 Any party hereto may change its address or telecopy number for notices and other communications

 SECTION 9.02. Waivers; Amendments; Addition of Term or Revolving Tranches. (a) No failure or delay by the Administrative Agent or any Lender
in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right
or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder and under the other Loan Documents are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed
as a waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time. 
 (b) Except as provided in paragraph (d) of this Section, none of this Agreement, any other Loan Document or any provision hereof or thereof may be waived, amended or modified except, in the case of this
Agreement, pursuant to an agreement or agreements in writing entered into by Level 3, the Borrower and the Required Lenders or, 
  

 102 








 in the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the
Administrative Agent and the Loan Party or Loan Parties that are parties thereto, in each case with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of or impose additional
obligations on any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon without the written consent of each Lender affected thereby, (iii) postpone the
scheduled date of payment of the principal amount of any Loan or any interest thereon, or reduce the amount of, waive or excuse any such payment, without the written consent of each Lender affected thereby, (iv) change Section 2.12(b) or
(c) in a manner that would alter the pro rata sharing of payments required thereby without the written consent of each Lender (except as provided in paragraph (d) of this Section), (v) change any of the provisions of this Section or
the definition of “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders required to waive, amend or modify any rights thereunder or make any determination or grant any consent
thereunder, without the written consent of each Lender (except as provided in paragraph (d) of this Section), (vi) release Level 3 or any other Guarantor from its Guarantee of the Obligations under the Guarantee Agreement (except as
expressly provided in Sections 6.07, 6.08, 6.10 or 9.14 or in the Guarantee Agreement), or limit its liability in respect of any such Guarantee, without the written consent of each Lender, (vii) release all or any substantial part of the
Collateral from the Liens of the Security Documents (except as expressly provided in Sections 6.07, 6.08, 6.10 or 9.14 or in Collateral Agreement), or subordinate such Liens, without the written consent of each Lender or (viii) except to the
extent necessary to comply with applicable law, amend or modify Section 9.04 in a manner that would by the terms of such amendment or waiver, as applicable, restrict the ability of the Lenders to make assignments, without the written consent of
each Lender, provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, without the prior written consent of the Administrative Agent. 
 (c) If, in connection with any proposed change, waiver, discharge or termination of any of the provisions of this Agreement referred to in any of
clauses (i) through (vii) of the first proviso in paragraph (b) of this Section, the consent of the Required Lenders shall be obtained but the consent of one or more other Lenders whose consent is sought shall not be obtained, then
the Borrower shall have the right, so long as all non-consenting Lenders whose individual consents are sought are treated as described in either clauses (A) or (B) below, to either (A) replace each such non-consenting Lender or
Lenders with one or more replacement Lenders in accordance with the provisions of Section 2.13(b) so long as, at the time of such replacement, each such replacement Lender consents to the proposed change, waiver, discharge or termination or
(B) repay the outstanding Loans of each such non-consenting Lender in accordance with Sections 2.05(a) and 2.10; provided that, unless the Loans that are repaid pursuant to preceding clause (B) are immediately replaced in full at
such time through the addition of new Lenders or the increase of the outstanding Loans of existing Lenders (who in each case must specifically consent thereto), then in the case of any action pursuant to preceding clause (B) each Lender
(determined after giving effect to the proposed action) shall specifically consent thereto. 
  

 103 








 (d) Notwithstanding anything in paragraph (b) of this Section to the contrary, this Agreement and
the other Loan Documents may be amended at any time and from time to time to establish revolving credit commitments or one or more additional classes of term loans by an agreement in writing entered into by Level 3, the Borrower, the
Administrative Agent, the Collateral Agent and each person (including any Lender) that shall agree to provide such a revolving credit commitment or make a term loan of any class so established (but without the consent of any other Lender), and each
such person that shall not already be a Lender shall, at the time such agreement becomes effective, become a Lender with the same effect as if it had originally been a Lender under this Agreement with the revolving credit commitment and/or term
loans set forth in such agreement; provided that the aggregate outstanding principal amount of the revolving credit commitments and term loans of all classes established pursuant to this paragraph shall at no time exceed the maximum principal
amount of the Indebtedness permitted to be incurred at such time under Section 6.01(b)(ii) and 6.02(b)(ii)). Any such agreement shall amend the provisions of this Agreement and the other Loan Documents to set forth the terms of the revolving
credit commitments or class of term loans established thereby (including the amount and final maturity thereof (which, in the case of any class of term loans, shall not be earlier than the Maturity Date), any provisions relating to amortization or
mandatory prepayments or offers to prepay (it being agreed that not more than 1% of the aggregate principal amount of the term loans of any class shall amortize during any calendar year prior to the Maturity Date and that provisions for mandatory
prepayments of and offers to prepay the term loans of any class may require such term loans to be prepaid or offered the right to be prepaid ratably with the Loans but shall not include any additional mandatory prepayment rights), the interest to
accrue and be payable thereon and any fees to be payable in respect thereof) and to effect such other changes (including changes to the provisions of this Section, Section 2.12 and the definition of “Required Lenders” and changes to
provide for a note of Level 3 LLC evidencing the advance of the proceeds of any loans) as Level 3, the Borrower and the Administrative Agent shall deem necessary or advisable in connection with the establishment of any such revolving
credit commitments or class of term loans; provided that no such agreement shall (i) effect any change described in any of clauses (i), (ii), (iii), (vi) or (vii) of paragraph (b) of this Section without the consent of
each person required to consent to such change under such clause (it being agreed, however, that the establishment of any revolving commitment or class of term loans will not, of itself, be deemed to effect any of the changes described in clauses
(vi) or (vii) of such paragraph (b)), or (ii) amend Article V, VI or VII to establish any affirmative or negative covenant, Event of Default or remedy that by its terms benefits any such revolving credit commitments or class of term
loans but not the Loans without the prior written consent of Lenders holding a majority in interest of the Loans. Without limiting the foregoing, a Qualified Receivable Facility permitted by Sections 6.01 and 6.02 may be established pursuant to and
in accordance with the provisions of this paragraph and may have a first priority Lien on Collateral consisting of Receivables, collections thereof and accounts established solely for the collection of such Receivables, and the Agent is authorized
and directed to enter into all such amendments to the Loan Documents as it shall deem necessary or advisable to establish such first priority Lien and to subordinate to such Lien on customary terms (as determined by the Agent and Level 3) the
Liens on such 
  

 104 








 Receivables securing the other Obligations. The loans of any class established pursuant to this paragraph shall, to the
extent provided in the amendment entered into in connection therewith, be entitled to all the benefits afforded by this Agreement and the other Loan Documents, and shall benefit equally and ratably (except as provided in the next preceding sentence)
from the Guarantees created by the Guarantee Agreement and security interests created by the Collateral Agreement and the other Security Documents. Level 3 and the Borrower shall take any actions reasonably required by the Administrative Agent
to ensure and/or demonstrate that the Guarantee and Collateral Requirement continues to be satisfied after the establishment of any such revolving credit commitments or class of term loans. Notwithstanding the foregoing of this paragraph (d), no
Regulated Grantor Subsidiary shall pledge any assets as collateral in support of any loans of any class established pursuant to this paragraph, nor shall any Regulated Guarantor Subsidiary Guarantee any such loans, unless it has obtained all
material (as determined in good faith by the General Counsel of Level 3) authorizations and consents of Federal and State Governmental Authorities required in order for such loans and all other loans outstanding hereunder to be secured by such
assets and guaranteed by such Regulated Guarantor Subsidiary. 
 (e) For each borrowing under an Additional Tranche, the Borrower shall use
the net proceeds of each such issuance and additional funds as necessary to lend to Level 3 LLC an amount equal to the principal amount of the Additional Tranche so issued, and the principal amount of the Loan Proceeds Note shall be increased
by such amount. 
 SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) Level 3 and the Borrower shall pay, on a joint and
several basis, (i) all reasonable out-of-pocket expenses incurred by the Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Agent, in connection with all ministerial activities in the
administration of the Loan Documents and any amendments, modifications or waivers of the provisions thereof and (ii) all reasonable out-of-pocket expenses incurred by the Agent and its Affiliates and each Lender in connection with the
enforcement of the Loan Documents, including rights under this Section, or in connection with the Loans, but Level 3 and the Borrower shall only be liable for the fees and expenses of counsel for the Agent and one other counsel for all such
other Persons (as well as separate local and regulatory counsel). The Borrower also shall pay all Lien search, filing, recording and similar fees incurred by the Collateral Agent in connection with the creation and perfection of the security
interests contemplated by the Loan Documents (other than the filing fees in connection with any local fixture filings and the expenses in connection with obtaining real estate descriptions for fixture filings). 
 (b) Level 3 and the Borrower shall indemnify, on a joint and several basis, the Agent, each Related Party of the Agent (each such Person being
called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of any Loan Document or any other agreement or instrument contemplated 
  

 105 








 hereby or thereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the
consummation of the Transactions or any other transactions contemplated hereby or thereby, or the Collateral, (ii) any Loan or the use of the proceeds thereof, (iii) any actual or alleged presence or release of Hazardous Materials on or
from any property owned or operated by Level 3, the Borrower or any of the Subsidiaries of Level 3, or any Environmental Liability related in any way to Level 3, the Borrower or any of the Subsidiaries of Level 3, or
(iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided
that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have
resulted from the gross negligence or willful misconduct of such Indemnitee. It is agreed that the expenses for which Level 3 and the Borrower agree to indemnify the Agent under this paragraph shall not include expenses associated with
(i) the arrangement and syndication of the Loans, (ii) the preparation, execution and delivery of the Loan Documents, (iii) the enforcement of the Loan Documents or (iv) the filing fees in connection with any local fixture
filings and the expenses in connection with obtaining real estate descriptions for fixture filings; provided, that nothing in this sentence shall have the effect of reducing any rights of the Agent or its Affiliates pursuant to paragraph
(a) of this Section or of reducing the Borrower’s responsibility for expenses related to claims, litigation, investigations or proceedings referred to in clause (iv) of the immediately preceding sentence. 
 (c) To the extent that Level 3 and the Borrower fail to pay any amount required to be paid by them to the Agent or any Related Party of the Agent
under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Agent such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought), based on
the amount of its Commitment or outstanding Loans or, if no Loans shall be outstanding, on the amount of its Loans on the most recent date on which Loans were outstanding, of such unpaid amount; provided that (i) the unreimbursed expense
or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Agent in its capacity as such and (ii) such indemnity shall not, as to the Agent or any Related Party, be available to
the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of the Agent or
such Related Party, as the case may be. 
 (d) To the extent permitted by applicable law, neither Level 3 nor the Borrower shall assert,
and each hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of this
Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof. 
  

 106 








 (e) All amounts due under this Section shall be payable promptly after written demand therefor.

 SECTION 9.04. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto, the Indemnitees and their respective successors and assigns permitted hereby, except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of
each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section.
Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, Indemnitees, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the
Related Parties of the Agent) any legal or equitable right, remedy or claim under or by reason of this Agreement. 
 (b) Any Lender may
assign to one or more assignees all or a portion of its rights under this Agreement (including all or a portion of the Loans at the time owing to it) to an Eligible Transferee; provided, that (i) except in the case of an assignment to a
Lender, the amount of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall be an integral multiple
of $1,000,000 (or the entire remaining amount of the assigning Lender’s Loans, if less than $1,000,000) unless the Administrative Agent shall otherwise consent, provided that (A) in the event of concurrent assignments to two or
more assignees that are Affiliates of one another, or to two or more Approved Funds managed by the same investment advisor or by affiliated investment advisors, all such concurrent assignments shall be aggregated in determining compliance with this
subsection and (B) in the event of concurrent assignments to or by two or more assignors that are Affiliates of one another, or to or by two or more Approved Funds managed by the same investment advisor or by affiliated investment advisors, all
such concurrent assignments shall be aggregated in determining compliance with this subsection; (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under
this Agreement; (iii) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 (except that in the event of (A) concurrent
assignments to two or more assignees that are Affiliates of one another, or to two or more Approved Funds managed by the same investment advisor or by affiliated investment advisors or (B) concurrent assignments by two or more assignees that
are Affiliates of one another, or by two or more Approved Funds managed by the same investment advisor or by affiliated investment advisors, only one such fee shall be payable); and (iv) the assignee, if it shall not be a Lender, shall deliver
to the Administrative Agent an Administrative Questionnaire. 
 (c) Subject to acceptance and recording thereof pursuant to
paragraph (d) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the 
  

 107 








 interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement,
and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the
assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.09, 2.10, 2.11 and 9.03). Any assignment or transfer by a Lender
of rights or obligations under this Agreement that does not comply with this Section shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (f) of
this Section. Each assignment hereunder shall be deemed to be an assignment of the related rights under the Security Documents. 
 (d) The
Administrative Agent shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans
owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender at any reasonable
time and from time to time upon reasonable prior notice. Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee
shall already be a Lender hereunder) and the processing and recordation fee referred to in paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the
Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. 
 (e) By executing and delivering an Assignment and Assumption, the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as
follows: (i) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim and that its Commitment and the outstanding balances of its Loans, in each case
without giving effect to assignments thereof that have not become effective, are as set forth in such Assignment and Assumption; (ii) except as set forth in clause (i) above, such assigning Lender makes no representation or warranty
and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or any other Loan Document or any other instrument or document furnished pursuant hereto or thereto, or the
execution, legality, validity, enforceability, genuineness, sufficiency or value of any of the foregoing, or the financial condition of the Loan Parties or the performance or observance by the Loan Parties of any of their obligations under this
Agreement or under any other Loan Document or any other instrument or document furnished pursuant hereto or thereto; (iii) each of the assignee and the assignor represents and warrants that it is 
  

 108 








 legally authorized to enter into such Assignment and Assumption; (iv) such assignee confirms that it has received a
copy of this Agreement, together with copies of any amendments or consents entered into prior to the date of such Assignment and Assumption and copies of the most recent financial statements delivered pursuant to Section 5.01 and such other
documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Assumption; (v) such assignee will independently and without reliance upon the Agents, such assigning Lender
or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (vi) such assignee appoints and authorizes
the Agents to take such action as agents on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to them by the terms hereof and thereof, together with such powers as are reasonably incidental
thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all the obligations that by the terms of this Agreement are required to be performed by it as a Lender. 
 (f) (i) Any Lender may, without the consent of the Borrower, or the Administrative Agent, sell participations to one or more other Persons (each a
“Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (i) such Lender’s
obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other
Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not,
without the consent of the Participant, agree to any amendment, modification or waiver that affects such Participant and that, under Section 9.02(b), would require the consent of each affected Lender. Subject to paragraph (f)(ii) of this
Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.09, 2.10 and 2.11 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this
Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.12(c) as though it were a Lender.

 (ii) A Participant shall not be entitled to receive any greater payment under Section 2.09, 2.10 or 2.11 than the
applicable Lender would have been entitled to receive with respect to the participation sold to such Participant unless the sale of the participation to such Participant is made with the Borrower’s prior written consent, which consent shall
specifically refer to this exception. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.11 unless the Borrower is notified of the participation sold to such Participant and such
Participant agrees, for the benefit of the Borrower, to comply with Section 2.11(e) as though it were a Lender. 
  

 109 








 (g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights
under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided
that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 
 SECTION 9.05. Survival. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in the
certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan
Documents and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any other amount payable under this Agreement is outstanding and
unpaid and so long as the Commitments have not expired or terminated. The provisions of Sections 2.09, 2.10, 2.11 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions
contemplated hereby, the repayment of the Loans or the termination of this Agreement or any provision hereof. 
 SECTION 9.06.
Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall
constitute a single contract. Delivery of an executed signature page to this Agreement by facsimile or electronic transmission shall be effective as delivery of a manually signed counterpart of this Agreement. This Agreement, the other Loan
Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. This Agreement shall become effective as provided in Section 4.01. 
 SECTION 9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

 SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be continuing and the Loans shall have become due and
payable pursuant to Article VII, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all 
  

 110 








 deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time
owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such
Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may
have. 
 SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in
accordance with and governed by the law of the State of New York. 
 (b) Each of Level 3 and the Borrower hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any
appellate court from any thereof, in any action or proceeding arising out of or relating to any Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all
claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent or
any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against Level 3, the Borrower or its properties in the courts of any jurisdiction. 
 (c) Each of Level 3 and the Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any
objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
 (d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this
Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
 SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE 
  

 111 








 TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO
(A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT
IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
 SECTION 9.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be
taken into consideration in interpreting, this Agreement. 
 SECTION 9.12. Confidentiality. The Administrative Agent and each Lender
agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other
advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory
authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to any pledgee
referred to in Section 9.04(g) or to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (g) with the consent of the Borrower, (h) to the extent
such Information (i) becomes publicly available other than as a result of a breach of this Section, (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than Level 3 or the
Borrower, (i) to any direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty
agrees to be bound by the provisions of this Section or (j) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized rating agency that requires access to information about a Lender’s
investment portfolio in connection with ratings issued with respect to such Lender. For the purposes of this Section, “Information” means all information received from Level 3 or the Borrower relating to Level 3 or the Borrower
or its business (including information obtained through the exercise of a Lender’s rights under Sections 5.01) other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to
disclosure by Level 3 or the Borrower. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree
of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. 
  

 112 








 SECTION 9.13. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any
time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the
“Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all
Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall
be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds
Effective Rate to the date of repayment, shall have been received by such Lender. 
 SECTION 9.14. Release of Subsidiary Loan Parties and
Collateral. (a) Notwithstanding any contrary provision herein or in any other Loan Document, if Level 3 shall request the release under any Security Document of (i) any of its Subsidiaries (other than the Borrower or Level 3 LLC)
or any Collateral to be sold or otherwise disposed of (including through the sale or disposition of any Subsidiary (other than the Borrower or Level 3 LLC) owning any such Subsidiary or Collateral) to a Person other than Level 3 or a
Subsidiary of Level 3 in a transaction permitted under the terms of this Agreement (including to the extent permitted by Section 6.07, 6.08 or 6.10), (ii) any Receivables, collections thereof and accounts established solely for the
collection of such Receivables to secure the Incurrence of Indebtedness pursuant to a Qualified Receivable Facility as permitted by Section 6.01(b)(ii) or 6.02(b)(ii) or (iii) any Property that is to become subject to any Lien permitted to
be Incurred under Section 6.05(ii)(3) or (4), and shall deliver to the Collateral Agent a certificate to the effect that such sale or other disposition and the application of the proceeds thereof will comply with the terms of this Agreement and
that no Event of Default shall have occurred and be continuing, the Collateral Agent, if satisfied that the applicable certificate is correct, and if satisfied with any arrangements for the receipt and deposit of proceeds of such transaction to the
extent required under Section 6.07(b), shall, unless an Event of Default has occurred and is continuing, execute and deliver all such instruments, releases, financing statements or other agreements, and take all such further actions, as shall
be necessary to effectuate the release of such Subsidiary or such Collateral substantially simultaneously with or at any time after the completion of such sale or other disposition; provided that if the Collateral to be sold or otherwise
disposed of is sold or otherwise disposed of by a Grantor in a transaction permitted by the Credit Agreement to a Person other than Level 3 or a Subsidiary of Level 3, then such Collateral shall be automatically released from any Lien
created by this Agreement or any other Loan Document upon the effectiveness of such sale or disposition. Any such release shall be without recourse to, or representation or warranty by, the Collateral Agent and shall not require the consent of any
Lender. The Collateral Agent shall execute and deliver all such releases, termination statements or other instruments, and take all such further actions, as shall be necessary to effectuate or confirm any release of Collateral required by this
paragraph. 
  

 113 








 (b) Without limiting the provisions of Section 9.03, Level 3 and the Borrower shall reimburse the
Collateral Agent for all reasonable out-of-pocket costs and expenses, including the reasonable fees, charges and disbursements of counsel, incurred by it in connection with any action contemplated by this Section. 
 (c) No such termination or cessation shall release, reduce or otherwise adversely affect the obligations of any other Loan Party under this Agreement or
any other Loan Document, all of which obligations continue to remain in full force and effect. 
 SECTION 9.15. Senior Debt Status. In
the event that Level 3 or any Subsidiary of Level 3 shall at any time issue or have outstanding any Indebtedness that by its terms is subordinated to any other Indebtedness of Level 3 or such Subsidiary, Level 3 shall take or
cause such Subsidiary to take all such actions as shall be necessary to cause the Obligations to constitute senior indebtedness (however denominated) in respect of such subordinated Indebtedness and to enable the Lenders to have and exercise any
payment blockage or other remedies available or potentially available to holders of senior indebtedness under the terms of such subordinated Indebtedness. Without limiting the foregoing, the Obligations are hereby designated as “senior
indebtedness” and, if relevant, as “designated senior indebtedness” in respect of all such subordinated Indebtedness and are further given all such other designations as shall be required under the terms of any such subordinated
Indebtedness in order that the Lenders may have and exercise any payment blockage or other remedies available or potentially available to holders of senior indebtedness under the terms of such subordinated indebtedness. 
 SECTION 9.16. No Fiduciary Relationship. Level 3 and the Borrower, on behalf of themselves and the Subsidiaries, agree that in connection with all
aspects of the transactions contemplated hereby and any communications in connection therewith, Level 3, the Borrower, the Subsidiaries and their Affiliates, on the one hand, and the Agent and the Lenders and their Affiliates, on the other hand,
will have a business relationship that does not create, by implication or otherwise, any fiduciary duty on the part of the Agent, the Lenders, or their Affiliates, and no such duty will be deemed to have arisen in connection with any such
transactions or communications.
