margin for any Revolving Loans or Swingline Loans than that described in the immediately preceding sentence (each, a “Start Date”) to and including the applicable End Date described below, the Applicable Margins for such Tranches of
Loans (hereinafter, the “Adjustable Applicable Margins”) shall be those set forth below opposite the Total Leverage Ratio indicated to have been achieved in any certificate delivered in accordance with the following sentences:

  

							
	 Total Leverage Ratio
	  	Revolving Loan
Eurodollar Margin	 	 	Revolving Loan and
Swingline Loan
Base Rate Margin	 
	 Equal to or greater than 4.00 to 1.00

	  	3.00	%	 	2.00	%
	 Less than 3.00 to 1.00
	  	2.75	%	 	1.75	%

 The Total Leverage Ratio used in a determination of Adjustable Applicable Margins shall be
determined based on the delivery of a certificate of the Borrower (each, a “Quarterly Pricing Certificate”) by an Authorized Officer of the Borrower to the Administrative Agent (with a copy to be sent by the Administrative Agent to
each Lender), within 45 days after the last day of any fiscal quarter of the Borrower (or within 90 days after the last day of the fourth fiscal quarter of the Borrower). The Quarterly Pricing Certificate shall set forth the calculation of the Total
Leverage Ratio as at the last day of the Test Period ended immediately prior to the relevant Start Date and the Adjustable Applicable Margins which shall be thereafter applicable (until such Adjustable Applicable Margins are changed or cease to
apply in accordance with the following sentences). The Adjustable Applicable Margins so determined shall apply, except as set forth in the succeeding sentence, from the relevant Start Date to the earlier of (x) the date on which the next
Quarterly Pricing Certificate is delivered to the Administrative Agent or (y) the date which is 45 days (or 90 days in the case of the fourth fiscal quarter of the Borrower) following the last day of the fiscal quarter of the Borrower for which
the Adjustable Applicable Margins were most recently determined pursuant to this definition (such earlier date, the “End Date”), at which time, if no Quarterly Pricing Certificate has been delivered to the Administrative Agent
indicating an entitlement to new Adjustable Applicable Margins (and thus commencing a new Start Date), the Adjustable Applicable Margins shall be those set forth in the first sentence of this definition (such Adjustable Applicable Margins as so

  

 -3- 

 
determined, the “Highest Adjustable Applicable Margins”). Notwithstanding anything to the contrary contained above in this definition, the
Adjustable Applicable Margins for Revolving Loans and Swingline Loans shall be the Highest Adjustable Applicable Margins (x) at all times during which a Default or an Event of Default shall occur and be continuing and (y) at all times

 “Asset Sale” shall mean any sale, transfer or other disposition by the Borrower or any of its Subsidiaries to any Person (including by
way of redemption by such Person) other than to the Borrower or a Wholly-Owned Subsidiary of the Borrower of any asset (including, without limitation, any Capital Stock or other securities of, or Equity Interests in, another Person), but excluding
sales of inventory in the ordinary course of business and sales, transfers or other dispositions of assets pursuant to Sections 10.02(ii), (v), (vi), (vii), (viii), (ix), (x), (xii), (xiii), and (xiv). For purposes of this Agreement, and

other Loan designated or deemed designated as such by the Borrower at the time of the incurrence thereof or conversion thereto.

 (b) Subject to and upon the terms and conditions set forth herein, each Lender with an Incremental Term Loan Commitment for a

an amount equal to the Total Revolving Loan Commitment at such time, and (v) shall not exceed in aggregate principal amount at any time outstanding the Maximum Swingline Amount. Notwithstanding anything to the contrary contained in this
Section 2.01(d), (i) the Swingline Lender shall not be obligated to make any Swingline Loans at a time when a Lender Default exists with respect to an RL Lender unless the Swingline Lender has entered into arrangements satisfactory to it
and the Borrower to eliminate the Swingline Lender’s risk with respect to the Defaulting Lender’s or Defaulting Lenders’ participation in such Swingline Loans, including by cash collateralizing such Defaulting Lender’s or
Defaulting Lenders’ RL Percentage of the outstanding Swingline Loans, and (ii) the Swingline Lender shall not make any Swingline Loan after it has received written notice from the Borrower, any other Credit Party or the Required Lenders
stating that a Default or an Event of Default exists and is continuing until such time as the Swingline Lender shall have received written notice (A) of rescission of all such notices from the party or parties originally delivering such notice
or notices or (B) of the waiver of such Default or Event of Default by the Required Lenders. 
 (e) On any Business Day, the Swingline
Lender may, in its sole discretion, give notice to the RL Lenders that the Swingline Lender’s outstanding Swingline Loans shall be funded with one or more Borrowings of Revolving Loans (provided that such notice shall be deemed to have
been automatically given upon the occurrence of a Default or an Event of Default under Section 11.05 or upon the exercise of any of the remedies provided in the last paragraph of Section 11), in which case one or more Borrowings of
Revolving Loans constituting Base Rate Loans (each such Borrowing, a “Mandatory Borrowing”) shall be made on the immediately succeeding Business Day by all RL Lenders pro rata based on each such RL Lender’s RL Percentage
(determined before giving effect to any termination of the Revolving Loan Commitments pursuant to the last paragraph of Section 11) and the proceeds thereof shall be applied directly by the Swingline Lender to repay the Swingline Lender for
such outstanding Swingline Loans. Each RL Lender hereby irrevocably agrees to make Revolving Loans upon one Business Day’s notice pursuant to each Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on
the date specified in writing by the Swingline Lender notwithstanding (i) the amount of the Mandatory Borrowing may not comply with the Minimum Borrowing Amount otherwise required hereunder, (ii) whether any conditions specified in
Section 7 are then satisfied, (iii) whether a Default or an Event of Default then exists, (iv) the date of such Mandatory Borrowing, and (v) the amount of the Total Revolving Loan Commitment at such time. In the event that any
Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under the Bankruptcy Code with respect to the Borrower), then each RL Lender
hereby agrees that it shall forthwith purchase (as of the date the Mandatory Borrowing would otherwise have occurred, but adjusted for any payments received from the 

  

 -41- 

 
Borrower on or after such date and prior to such purchase) from the Swingline Lender such participations in the outstanding Swingline Loans as shall be
necessary to cause the RL Lenders to share in such Swingline Loans ratably based upon their respective RL Percentages (determined before giving effect to any termination of the Revolving Loan Commitments pursuant to the last paragraph of
Section 11), provided that (x) all interest payable on the Swingline Loans shall be for the account of the Swingline Lender until the date as of which the respective participation is required to be purchased and, to the extent
attributable to the purchased participation, shall be payable to the participant from and after such date and (y) at the time any purchase of participations pursuant to this sentence is actually made, the purchasing RL Lender shall be required
to pay the Swingline Lender interest on the principal amount of participation purchased for each day from and including the day upon which the Mandatory Borrowing would otherwise have occurred to but excluding the date of payment for such
participation, at the overnight Federal Funds Rate for the first three days and at the interest rate otherwise applicable to Revolving Loans maintained as Base Rate Loans hereunder for each day thereafter. 
 2.02. Minimum Amount of Each Borrowing. The aggregate principal amount of each Borrowing of Loans under a respective Tranche shall not be less
than the Minimum Borrowing Amount applicable to such Tranche. More than one Borrowing may occur on the same date, but at no time shall there be outstanding more than fifteen Borrowings of Eurodollar Loans in the aggregate for all Tranches of Loans.

 2.03. Notice of Borrowing. (a) Whenever the Borrower desires to incur (x) Eurodollar Loans hereunder, the Borrower shall
give the Administrative Agent at the Notice Office at least three Business Days’ prior notice of each Eurodollar Loan to be incurred hereunder and (y) Base Rate Loans hereunder (excluding Swingline Loans and Revolving Loans made pursuant
to a Mandatory Borrowing), the Borrower shall give the Administrative Agent at the Notice Office at least one Business Day’s prior notice of each Base Rate Loan to be incurred hereunder, provided that (in each case) any such notice shall
be deemed to have been given on a certain day only if given before 11:00 A.M. (New York City time) on such day. Each such notice (each, a “Notice of Borrowing”), except as otherwise expressly provided in Section 2.10, shall be
irrevocable and shall be in writing, or by telephone promptly confirmed in writing, in the form of Exhibit A-1, appropriately completed to specify: (i) the aggregate principal amount of the Loans to be incurred pursuant to such Borrowing,
(ii) the date of such Borrowing (which shall be a Business Day), (iii) whether the Loans being incurred pursuant to such Borrowing shall constitute Initial Term Loans, Incremental Term Loans or Revolving Loans and, if Incremental Term
Loans, the specific Tranche thereof, (iv) whether the Loans being incurred pursuant to such Borrowing are to be initially maintained as Base Rate Loans or, to the extent permitted hereunder, Eurodollar Loans and, if Eurodollar Loans, the
initial Interest Period to be applicable thereto, and (v) in the case of a Borrowing of Revolving Loans the proceeds of which are to be utilized to finance, in whole or in part, a Permitted Acquisition (or to pay any fees and expenses incurred
in connection therewith), the amount of the Total Unutilized Revolving Loan Commitment after giving effect to such Borrowing. The Administrative Agent shall promptly give each Lender which is required to make Loans of the Tranche specified in the
respective Notice of Borrowing, notice of such proposed Borrowing, of such Lender’s proportionate share thereof and of the other matters required by the immediately preceding sentence to be specified in the Notice of Borrowing. 
  

 -42- 

 (b) (i) Whenever the Borrower desires to incur Swingline Loans hereunder, the Borrower shall give
the Swingline Lender no later than 1:00 P.M. (New York City time) on the date that a Swingline Loan is to be incurred, written notice or telephonic notice promptly confirmed in writing of each Swingline Loan to be incurred hereunder. Each such
notice shall be irrevocable and specify in each case (A) the date of Borrowing (which shall be a Business Day), (B) the aggregate principal amount of the Swingline Loans to be incurred pursuant to such Borrowing, and (C) in the case of a Borrowing
of Swingline Loans the proceeds of which are to be utilized to finance, in whole or in part, a Permitted Acquisition (or to pay any fees and expenses incurred in connection therewith), the amount of the Total Unutilized Revolving Loan Commitment
after giving effect to such Borrowing. 
 (ii) Mandatory Borrowings shall be made upon the notice specified in Section 2.01(e), with the
Borrower irrevocably agreeing, by its incurrence of any Swingline Loan, to the making of the Mandatory Borrowings as set forth in Section 2.01(e). 
 (c) Without in any way limiting the obligation of the Borrower to confirm in writing any telephonic notice of any Borrowing or prepayment of Loans, the Administrative Agent or the Swingline Lender, as the case may be,
may act without liability upon the basis of telephonic notice of such Borrowing or prepayment, as the case may be, believed by the Administrative Agent or the Swingline Lender, as the case may be, in good faith to be from an Authorized Officer of
the Borrower, prior to receipt of written confirmation. In each such case, the Borrower hereby waives the right to dispute the Administrative Agent’s or the Swingline Lender’s record of the terms of such telephonic notice of such Borrowing
or prepayment of Loans, as the case may be, absent manifest error. 
 2.04. Disbursement of Funds. No later than 1:00 P.M. (New York
City time) on the date specified in each Notice of Borrowing (or (x) in the case of Swingline Loans, no later than 4:00 P.M. (New York City time) on the date specified pursuant to Section 2.03(b)(i) or (y) in the case of Mandatory
Borrowings, no later than 1:00 P.M. (New York City time) on the date specified in Section 2.01(e)), each Lender with a Commitment of the respective Tranche will make available its pro rata portion (determined in accordance with
Section 2.07) of each such Borrowing requested to be made on such date (or in the case of Swingline Loans, the Swingline Lender will make available the full amount thereof). All such amounts will be made available in Dollars and in immediately
available funds at the Payment Office, and the Administrative Agent will, except in the case of Revolving Loans made pursuant to a Mandatory Borrowing, make available to the Borrower at the Payment Office the aggregate of the amounts so made
available by the Lenders. Unless the Administrative Agent shall have been notified by any Lender prior to the date of Borrowing that such Lender does not intend to make available to the Administrative Agent such Lender’s portion of any
Borrowing to be made on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date of Borrowing and the Administrative Agent may (but shall not be obligated to), in
reliance upon such assumption, make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender, the Administrative Agent shall be entitled to recover such
corresponding amount on demand from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the Borrower and the Borrower shall
immediately 
  

 -43- 

 
pay such corresponding amount to the Administrative Agent. The Administrative Agent also shall be entitled to recover on demand from such Lender or the
Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to the Borrower until the date such corresponding amount is recovered
by the Administrative Agent, at a rate per annum equal to (i) if recovered from such Lender, the overnight Federal Funds Rate for the first three days and at the interest rate otherwise applicable to such Loans for each day thereafter and
(ii) if recovered from the Borrower, the rate of interest applicable to the respective Borrowing, as determined pursuant to Section 2.08. Nothing in this Section 2.04 shall be deemed to relieve any Lender from its obligation to make
Loans hereunder or to prejudice any rights which the Borrower may have against any Lender as a result of any failure by such Lender to make Loans hereunder. 
 2.05. Notes. (a) The Borrower’s obligation to pay the principal of, and interest on, the Loans made by each Lender shall be evidenced in the Register maintained by the Administrative Agent pursuant to
Section 13.15 and shall, if requested by such Lender, also be evidenced (i) in the case of Initial Term Loans, by a promissory note duly executed and delivered by the Borrower substantially in the form of Exhibit B-1, with blanks
appropriately completed in conformity herewith (each, an “Initial Term Note” and, collectively, the “Initial Term Notes”), (ii) in the case of Revolving Loans, by a promissory note duly executed and delivered
by the Borrower substantially in the form of Exhibit B-2, with blanks appropriately completed in conformity herewith (each, a “Revolving Note” and, collectively, the “Revolving Notes”), (iii) in the case of
Swingline Loans, by a promissory note duly executed and delivered by the Borrower substantially in the form of Exhibit B-3, with blanks appropriately completed in conformity herewith (the “Swingline Note”), and (iv) in the case
of Incremental Term Loans, by a promissory note duly executed and delivered by the Borrower substantially in the form of Exhibit B-4, with blanks appropriately completed in conformity herewith (each, an “Incremental Term Note” and,
collectively, the “Incremental Term Notes”). 
 (b) Each Lender will note on its internal records the amount of each Loan
made by it and each payment in respect thereof and prior to any transfer of any of its Notes will endorse on the reverse side thereof the outstanding principal amount of Loans evidenced thereby. Failure to make any such notation or any error in such
notation shall not affect the Borrower’s obligations in respect of such Loans. 
 (c) Notwithstanding anything to the contrary contained
above in this Section 2.05 or elsewhere in this Agreement, Notes shall only be delivered to Lenders which at any time specifically request the delivery of such Notes. No failure of any Lender to request or obtain a Note evidencing its Loans to
the Borrower shall affect or in any manner impair the obligations of the Borrower to pay the Loans (and all related Obligations) incurred by the Borrower which would otherwise be evidenced thereby in accordance with the requirements of this
Agreement, and shall not in any way affect the security or guaranties therefor provided pursuant to the various Credit Documents. Any Lender which does not have a Note evidencing its outstanding Loans shall in no event be required to make the
notations otherwise described in preceding clause (b). At any time when any Lender requests the delivery of a Note to evidence any of its Loans, the Borrower shall promptly execute and deliver to the respective Lender the requested Note in the
appropriate amount or amounts to evidence such Loans. 
  

 -44- 

 2.06. Conversions. The Borrower shall have the option to convert, on any Business Day, all or a
portion equal to at least the Minimum Borrowing Amount of the outstanding principal amount of Loans (other than Swingline Loans which may not be converted pursuant to this Section 2.06) made pursuant to one or more Borrowings (so long as of the
same Tranche) of one or more Types of Loans into a Borrowing (of the same Tranche) of another Type of Loan, provided that (i) except as otherwise provided in Section 2.10(b), Eurodollar Loans may be converted into Base Rate Loans
only on the last day of an Interest Period applicable to the Loans being converted and no such partial conversion of Eurodollar Loans shall reduce the outstanding principal amount of such Eurodollar Loans made pursuant to a single Borrowing to less
than the Minimum Borrowing Amount applicable thereto, (ii) unless the Required Lenders otherwise agree, Base Rate Loans may only be converted into Eurodollar Loans if no Default or Event of Default is in existence on the date of the conversion,
(iii) unless the Administrative Agent has otherwise agreed or has determined that the Syndication Date has occurred (at which time this clause (iii) shall no longer be applicable), conversions of Base Rate Loans into Eurodollar Loans may
only be made if any such conversion is effective on the first day of the Interest Period referred to in clause (B) of Section 2.01(a)(iii) and so long as such conversion does not result in a greater number of Borrowings of Eurodollar Loans
than are permitted under Section 2.01(a)(iii), and (iv) no conversion pursuant to this Section 2.06 shall result in a greater number of Borrowings of Eurodollar Loans than is permitted under Section 2.02. Each such conversion
shall be effected by the Borrower by giving the Administrative Agent at the Notice Office prior to 11:00 A.M. (New York City time) at least (x) in the case of conversions of Base Rate Loans into Eurodollar Loans, three Business Days’ prior
notice and (y) in the case of conversions of Eurodollar Loans into Base Rate Loans, one Business Day’s prior notice (each, a “Notice of Conversion/Continuation”), in each case in the form of Exhibit A-2, appropriately
completed to specify the Loans to be so converted, the Borrowing or Borrowings pursuant to which such Loans were incurred and, if to be converted into Eurodollar Loans, the Interest Period to be initially applicable thereto. The Administrative Agent
shall give each Lender prompt notice of any such proposed conversion affecting any of its Loans. 
 2.07. Pro Rata Borrowings. All
Borrowings of Initial Term Loans, Incremental Term Loans and Revolving Loans under this Agreement shall be incurred from the Lenders pro rata on the basis of their Initial Term Loan Commitments, applicable Incremental Term Loan Commitments or
Revolving Loan Commitments, as the case may be, provided that all Mandatory Borrowings shall be incurred from the RL Lenders pro rata on the basis of their RL Percentages. It is understood that no Lender shall be responsible for any
default by any other Lender of its obligation to make Loans hereunder and that each Lender shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to make its Loans hereunder.

 2.08. Interest. (a) The Borrower agrees to pay interest in respect of the unpaid principal amount of each Base Rate Loan from
the date of Borrowing thereof until the earlier of (i) the maturity thereof (whether by acceleration or otherwise) and (ii) the conversion of such Base Rate Loan to a Eurodollar Loan pursuant to Section 2.06 or 2.09, as applicable, at
a rate per annum which shall be equal to the sum of the relevant Applicable Margin plus the Base Rate, each as in effect from time to time. 
  

 -45- 

 (b) The Borrower agrees to pay interest in respect of the unpaid principal amount of each Eurodollar Loan
from the date of Borrowing thereof until the earlier of (i) the maturity thereof (whether by acceleration or otherwise) and (ii) the conversion of such Eurodollar Loan to a Base Rate Loan pursuant to Section 2.06, 2.09 or 2.10, as
applicable, at a rate per annum which shall, during each Interest Period applicable thereto, be equal to the sum of the relevant Applicable Margin as in effect from time to time during such Interest Period plus the Eurodollar Rate for such
Interest Period. 
 (c) Overdue principal and, to the extent permitted by law, overdue interest in respect of each Loan shall, in each case,
bear interest at a rate per annum equal to the greater of (x) the rate which is 2% in excess of the rate then borne by such Loans and (y) the rate which is 2% in excess of the rate otherwise applicable to Base Rate Loans of the respective
Tranche from time to time, and all other overdue amounts payable hereunder and under any other Credit Document shall bear interest at a rate per annum equal to the rate which is 2% in excess of the rate applicable to Revolving Loans that are
maintained as Base Rate Loans from time to time. Interest that accrues under this Section 2.08(c) shall be payable on demand. 
 (d)
Accrued (and theretofore unpaid) interest shall be payable (i) in respect of each Base Rate Loan, (x) quarterly in arrears on each Quarterly Payment Date, (y) on the date of any repayment or prepayment in full of all outstanding Base
Rate Loans of any Tranche, and (z) at maturity (whether by acceleration or otherwise) and, after such maturity, on demand, and (ii) in respect of each Eurodollar Loan, (x) on the last day of each Interest Period applicable thereto
and, in the case of an Interest Period in excess of three months, on each date occurring at three month intervals after the first day of such Interest Period, and (y) on the date of any repayment or prepayment (on the amount repaid or prepaid),
at maturity (whether by acceleration or otherwise) and, after such maturity, on demand. 
 (e) Upon each Interest Determination Date, the
Administrative Agent shall determine the Eurodollar Rate for each Interest Period applicable to the respective Eurodollar Loans and shall promptly notify the Borrower and the Lenders thereof. Each such determination shall, absent manifest error, be
final and conclusive and binding on all parties hereto. 
 2.09. Interest Periods. At the time the Borrower gives any Notice of
Borrowing or Notice of Conversion/Continuation in respect of the making of, or conversion into, any Eurodollar Loan (in the case of the initial Interest Period applicable thereto) or prior to 11:00 A.M. (New York City time) on the third
Business Day prior to the expiration of an Interest Period applicable to such Eurodollar Loan (in the case of any subsequent Interest Period), the Borrower shall have the right to elect the interest period (each, an “Interest
Period”) applicable to such Eurodollar Loan, which Interest Period shall, at the option of the Borrower (but otherwise subject to the provisions of clause (B) of the proviso in Section 2.01(a)(iii)), be a one, two, three, six or,
in the case of Revolving Loans only, to the extent approved by each Lender with a Revolving Loan Commitment, nine or twelve month period (or in the case of the initial Interest Period for a given Tranche of Incremental Term Loans that are to be
added to (and form a part of) a then existing Tranche of Term Loans, such other period, not to exceed one month, as is acceptable to the Administrative Agent), provided that (in each case): 
  

 -46- 

 (i) all Eurodollar Loans comprising a Borrowing shall at all times have the same Interest
Period; 
 (ii) the initial Interest Period for any Eurodollar Loan shall commence on the date of Borrowing of such Eurodollar
Loan (including the date of any conversion thereto from a Base Rate Loan) and each Interest Period occurring thereafter in respect of such Eurodollar Loan shall commence on the day on which the next preceding Interest Period applicable thereto
expires; 
 (iii) if any Interest Period for a Eurodollar Loan begins on a day for which there is no numerically corresponding
day in the calendar month at the end of such Interest Period, such Interest Period shall end on the last Business Day of such calendar month; 
 (iv) if any Interest Period for a Eurodollar Loan would otherwise expire on a day which is not a Business Day, such Interest Period shall expire on the next succeeding Business Day, provided, however,
that if any Interest Period for a Eurodollar Loan would otherwise expire on a day which is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the next preceding
Business Day; 
 (v) unless the Required Lenders otherwise agree, no Interest Period may be selected at any time when a
Default or an Event of Default is then in existence; 
 (vi) no Interest Period in respect of any Borrowing of any Tranche of
Loans shall be selected which extends beyond the Maturity Date for such Tranche of Loans; and 
 (vii) no Interest Period in
respect of any Borrowing of Term Loans shall be selected which extends beyond any date upon which a mandatory repayment of such Term Loans will be required to be made under Section 5.02(b), if the aggregate principal amount of such Term Loans
which have Interest Periods which will expire after such date will be in excess of the aggregate principal amount of such Term Loans then outstanding less the aggregate amount of such required repayment. 
 If by 11:00 A.M. (New York City time) on the third Business Day prior to the expiration of any Interest Period applicable to a Borrowing of Eurodollar Loans, the
Borrower has failed to elect, or is not permitted to elect, a new Interest Period to be applicable to such Eurodollar Loans as provided above, the Borrower shall be deemed to have elected to convert such Eurodollar Loans into Base Rate Loans
effective as of the expiration date of such current Interest Period. 
 2.10. Increased Costs, Illegality, etc. (a) In the event that
any Lender shall have determined (which determination shall, absent manifest error, be final and conclusive and binding upon all parties hereto but, with respect to clause (i) below, may be made only by the Administrative Agent): 
 (i) on any Interest Determination Date that, by reason of any changes arising after the date of this Agreement affecting the applicable
interbank Eurodollar market, 

  

 -47- 

 
adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of Eurodollar Rate; or

 (ii) at any time, that such Lender shall incur increased costs or reductions in the amounts received or receivable
hereunder with respect to any Eurodollar Loan because of (x) any change since the Effective Date in any applicable law or governmental rule, regulation, order, guideline or request (whether or not having the force of law) or in the
interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, order, guideline or request, such as, but not limited to: (A) a change in the basis of taxation of payment to any Lender of
the principal of or interest on such Eurodollar Loans or the Notes or any other amounts payable hereunder (except for changes in the rate of tax on, or determined by reference to, the net income or net profits of such Lender pursuant to the laws of
the jurisdiction in which it is organized or in which its principal office or applicable lending office is located or any subdivision thereof or therein) or (B) a change in official reserve requirements, but, in all events, excluding reserves
required under Regulation D to the extent included in the computation of the Eurodollar Rate and/or (y) other circumstances arising since the Effective Date affecting such Lender, the applicable interbank Eurodollar market or the position of
such Lender in such market; or 
 (iii) at any time, that the making or continuance of any Eurodollar Loan has been made
(x) unlawful by any law or governmental rule, regulation or order, (y) impossible by compliance by any Lender in good faith with any governmental request (whether or not having force of law) or (z) impracticable as a result of a
contingency occurring after the Effective Date which materially and adversely affects the interbank Eurodollar market; 
 then, and in any such event, such
Lender (or the Administrative Agent, in the case of clause (i) above) shall promptly give notice (by telephone promptly confirmed in writing) to the Borrower and, except in the case of clause (i) above, to the Administrative Agent of such
determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of clause (i) above, Eurodollar Loans shall no longer be available until such time as the Administrative
Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist, and any Notice of Borrowing or Notice of Conversion/Continuation given by the Borrower with respect to
Eurodollar Loans which have not yet been incurred (including by way of conversion) shall be deemed rescinded by the Borrower, (y) in the case of clause (ii) above, the Borrower agrees to pay to such Lender, upon such Lender’s written
request therefor, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender in its sole reasonable discretion shall determine) as shall be required to compensate such
Lender for such increased costs or reductions in amounts received or receivable hereunder (a written notice as to the additional amounts owed to such Lender, showing in reasonable detail the basis for the calculation thereof, submitted to the
Borrower by such Lender shall, absent manifest error, be final and conclusive and binding on all the parties hereto) and (z) in the case of clause (iii) above, the Borrower shall take one of the actions specified in Section 2.10(b) as
promptly as possible and, in any event, within any applicable time period required by law. 
  

 -48- 

 (b) At any time that any Eurodollar Loan is affected by the circumstances described in
Section 2.10(a)(ii), the Borrower may, and in the case of a Eurodollar Loan affected by the circumstances described in Section 2.10(a)(iii), the Borrower shall, either (x) if the affected Eurodollar Loan is then being made initially
or pursuant to a conversion, cancel such Borrowing by giving the Administrative Agent telephonic notice (confirmed in writing) on the same date that the Borrower was notified by the affected Lender or the Administrative Agent pursuant to
Section 2.10(a)(ii) or (iii) or (y) if the affected Eurodollar Loan is then outstanding, upon at least three Business Days’ written notice to the Administrative Agent, require the affected Lender to convert such Eurodollar Loan
into a Base Rate Loan, provided that, if more than one Lender is affected at any time, then all affected Lenders must be treated the same pursuant to this Section 2.10(b). 
 (c) If any Lender determines that after the Effective Date the introduction of or any change in any applicable law or governmental rule, regulation,
order, guideline, directive or request (whether or not having the force of law) concerning capital adequacy, or any change in interpretation or administration thereof by the NAIC or any Governmental Authority, central bank or comparable agency, will
have the effect of increasing the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender based on the existence of such Lender’s Commitments hereunder or its obligations hereunder, then
the Borrower agrees to pay to such Lender, upon its written demand therefor, such additional amounts as shall be required to compensate such Lender or such other corporation for the increased cost to such Lender or such other corporation or the
reduction in the rate of return to such Lender or such other corporation as a result of such increase of capital. In determining such additional amounts, each Lender will act reasonably and in good faith and will use averaging and attribution
methods which are reasonable, provided that such Lender’s determination of compensation owing under this Section 2.10(c) shall, absent manifest error, be final and conclusive and binding on all the parties hereto. Each Lender, upon
determining that any additional amounts will be payable pursuant to this Section 2.10(c), will give prompt written notice thereof to the Borrower, which notice shall show in reasonable detail the basis for calculation of such additional
amounts. 
 2.11. Compensation. The Borrower agrees to compensate each Lender, upon its written request (which request shall set forth
in reasonable detail the basis for requesting such compensation), for all losses, expenses and liabilities (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or reemployment of deposits or other
funds required by such Lender to fund its Eurodollar Loans but excluding loss of anticipated profits) which such Lender may sustain: (i) if for any reason (other than a default by such Lender or the Administrative Agent) a Borrowing of, or
conversion from or into, Eurodollar Loans does not occur on a date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation (whether or not withdrawn by the Borrower or deemed withdrawn pursuant to Section 2.10(a));
(ii) if any prepayment or repayment (including any prepayment or repayment made pursuant to Section 5.01, Section 5.02 or as a result of an acceleration of the Loans pursuant to Section 11) or conversion of any of its Eurodollar
Loans occurs on a date which is not the last day of an Interest Period with respect thereto; (iii) if any prepayment of any of its Eurodollar Loans is not made on any date specified in a notice of prepayment given by the Borrower; or
(iv) as a consequence of (x) any other default by the Borrower to repay Eurodollar 

  

 -49- 

 
Loans when required by the terms of this Agreement or any Note held by such Lender or (y) any election made pursuant to Section 2.10(b).

 2.12. Change of Lending Office. Each Lender agrees that on the occurrence of any event giving rise to the operation of
Section 2.10(a)(ii) or (iii), Section 2.10(c), Section 3.06 or Section 5.04 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans or Letters of Credit affected by such event, with the object of avoiding the consequence of the event giving rise to the operation of such Section, provided that such designation is made on such
terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage. Nothing in this Section 2.12 shall affect or postpone any of the obligations of the Borrower or the right of any Lender provided in
Sections 2.10, 3.06 and 5.04. 
 2.13. Replacement of Lenders. (x) If any Lender becomes a Defaulting Lender, (y) upon
the occurrence of any event giving rise to the operation of Section 2.10(a)(ii) or (iii), Section 2.10(c), Section 3.06 or Section 5.04 with respect to any Lender which results in such Lender charging to the Borrower increased
costs in excess of those being generally charged by the other Lenders or (z) in the case of a refusal by a Lender to consent to a proposed change, waiver, discharge or termination with respect to this Agreement which has been approved by the
Required Lenders as (and to the extent) provided in Section 13.12(b), the Borrower shall have the right, in accordance with Section 13.04(b), if no Default or Event of Default then exists or would exist after giving effect to such
replacement, to replace such Lender (the “Replaced Lender”) with one or more other Eligible Transferees, none of whom shall constitute a Defaulting Lender at the time of such replacement (collectively, the “Replacement
Lender”) and each of which shall be reasonably acceptable to the Administrative Agent or, in the case of a replacement as provided in Section 13.12(b) where the consent of the respective Lender is required with respect to less than all
Tranches of its Loans or Commitments, to replace the Commitments and/or outstanding Loans of such Lender in respect of each Tranche where the consent of such Lender would otherwise be individually required, with identical Commitments and/or Loans of
the respective Tranche provided by the Replacement Lender, provided that: 
 (a) at the time of any replacement
pursuant to this Section 2.13, the Replacement Lender shall enter into one or more Assignment and Assumption Agreements pursuant to Section 13.04(b) (and with all fees payable pursuant to such Section 13.04(b) to be paid by the
Replacement Lender and/or the Replaced Lender (as may be agreed to at such time by and among the Borrower, the Replacement Lender and the Replaced Lender)) pursuant to which the Replacement Lender shall acquire all of the Commitments and outstanding
Loans (or, in the case of the replacement of only (a) the Revolving Loan Commitment, the Revolving Loan Commitment and outstanding Revolving Loans and participations in Letter of Credit Outstandings and/or (b) the outstanding Term Loans of
a Tranche, the outstanding Term Loans of such Tranche) of, and in each case (except for the replacement of only the outstanding Term Loans of the respective Lender) all participations in Letters of Credit by, the Replaced Lender and, in connection
therewith, shall pay to (x) the Replaced Lender in respect thereof an amount equal to the sum of (A) an amount equal to the principal of, and all accrued interest on, all outstanding Loans of the respective Replaced Lender under each
Tranche with respect to which such Replaced Lender is being replaced, (B) an amount equal to all Unpaid 

  

 -50- 

 
Drawings (unless there are no Unpaid Drawings with respect to the Tranche being replaced) that have been funded by (and not reimbursed to) such Replaced
Lender, together with all then unpaid interest with respect thereto at such time and (C) an amount equal to all accrued, but theretofore unpaid, Fees owing to the Replaced Lender (but only with respect to the relevant Tranche, in the case of
the replacement of less than all Tranches of Loans then held by the respective Replaced Lender) pursuant to Section 4.01, (y) except in the case of the replacement of only the outstanding Term Loans of a Replaced Lender, each Issuing
Lender an amount equal to such Replaced Lender’s RL Percentage of any Unpaid Drawing relating to Letters of Credit issued by such Issuing Lender (which at such time remains an Unpaid Drawing) to the extent such amount was not theretofore funded
by such Replaced Lender and (z) in the case of any replacement of Revolving Loan Commitments, the Swingline Lender an amount equal to such Replaced Lender’s RL Percentage of any Mandatory Borrowing to the extent such amount was not
theretofore funded by such Replaced Lender to the Swingline Lender; and 
 (b) all obligations of the Borrower then owing to
the Replaced Lender (other than those (a) specifically described in clause (a) above in respect of which the assignment purchase price has been, or is concurrently being, paid, but including all amounts, if any, owing under
Section 2.11 or (b) relating to any Tranche of Loans and/or Commitments of the respective Replaced Lender which will remain outstanding after giving effect to the respective replacement) shall be paid in full to such Replaced Lender
concurrently with such replacement. 
 Upon receipt by the Replaced Lender of all amounts required to be paid to it pursuant to this Section 2.13, the
Administrative Agent shall be entitled (but not obligated) and authorized to execute an Assignment and Assumption Agreement on behalf of such Replaced Lender, and any such Assignment and Assumption Agreement so executed by the Administrative Agent
and the Replacement Lender shall be effective for purposes of this Section 2.13 and Section 13.04(b). Upon the execution of the respective Assignment and Assumption Agreement, the payment of amounts referred to in clauses (a) and
(b) above, recordation of the assignment on the Register by the Administrative Agent pursuant to Section 13.15 and, if so requested by the Replacement Lender, delivery to the Replacement Lender of the appropriate Note or Notes executed by
the Borrower, (x) the Replacement Lender shall become a Lender hereunder and, unless the respective Replaced Lender continues to have outstanding Term Loans and/or a Revolving Loan Commitment hereunder, the Replaced Lender shall cease to
constitute a Lender hereunder, except with respect to indemnification provisions under this Agreement (including, without limitation, Sections 2.10, 2.11, 3.06, 5.04, 12.06, 13.01 and 13.06), which shall survive as to such Replaced Lender and
(y) except in the case of the replacement of only outstanding Term Loans pursuant to this Section 2.13, the RL Percentages of the Lenders shall be automatically adjusted at such time to give effect to such replacement. 
 2.14. Incremental Term Loan Commitments. (a) The Borrower shall have the right, after the occurrence of the Syndication Date, to request from time
to time (by written notice to the Administrative Agent, who shall send a copy of such notice to each Lender) that one or more Lenders (and/or one or more other Persons, reasonably acceptable to the Administrative Agent, which will become Lenders as
provided below) provide Incremental Term Loan Commitments and, subject to the terms and conditions contained in this Agreement and the 

  

 -51- 

 
relevant Incremental Term Loan Commitment Agreement, make Incremental Term Loans pursuant thereto, so long as (w) no Default or Event of Default then
exists or would result therefrom, (x) all Incremental Term Loans are incurred on the date of the effectiveness of the respective Incremental Term Loan Commitment Agreement pursuant to which the related Incremental Term Loan Commitments are
provided, (y) the Borrower shall have demonstrated to the Administrative Agent’s reasonable satisfaction that the full amount of the respective Incremental Term Loans may be incurred without violating the terms of any Permitted
Subordinated Debt, any other material Indebtedness of the Borrower or any of its Subsidiaries or the documentation governing any such Indebtedness and (z) calculations are made by the Borrower demonstrating compliance, on a Pro Forma
Basis, with each of the Financial Covenants for the Calculation Period most recently ended prior to the date of the respective incurrence of Incremental Term Loans (determined as if the full amount of such Incremental Term Loans had been incurred on
the first day of such Calculation Period); it being understood and agreed, however, that (i) no Lender shall be obligated to provide an Incremental Term Loan Commitment as a result of any such request by the Borrower, and until such
time, if any, as such Lender has agreed in its sole discretion to provide an Incremental Term Loan Commitment and executed and delivered to the Administrative Agent an Incremental Term Loan Commitment Agreement as provided in clause (b) of this
Section 2.14, such Lender shall not be obligated to fund any Incremental Term Loans, (ii) any Lender (or any other Person, reasonably acceptable to the Administrative Agent, which will qualify as an Eligible Transferee) may so provide an
Incremental Term Loan Commitment without the consent of any other Lender, (iii) the amount of each Tranche of Incremental Term Loan Commitments (whether constituting a new Tranche of Incremental Term Loans or being added to (and thereafter
constituting a part of) a then outstanding Tranche of Term Loans) shall be in a minimum aggregate amount (for all Lenders and Eligible Transferees which will become Lenders) of at least $25,000,000, (iv) the aggregate amount of all Incremental
Term Loan Commitments permitted to be provided pursuant to this Section 2.14 shall not exceed $100,000,000, (v) the up-front fees and, if applicable, any unutilized commitment fees and/or other fees, payable to each Incremental Term Loan
Lender in respect of each Incremental Term Loan Commitment shall be separately agreed to by the Borrower, the Administrative Agent and each such Incremental Term Loan Lender, (vi) each Tranche of Incremental Term Loans shall (I) have an
Incremental Term Loan Maturity Date of no earlier than the Initial Term Loan Maturity Date, (II) have a Weighted Average Life to Maturity of no less than the Weighted Average Life to Maturity as then in effect for the Initial Term Loans and (III) be
subject to the Applicable Margins that are set forth in the Incremental Term Loan Commitment Agreement governing such Tranche of Incremental Term Loans, (vii) each Incremental Term Loan Commitment Agreement shall specifically designate the
Tranche or Tranches of the Incremental Term Loan Commitments being provided thereunder (which Tranche shall be a new Tranche (i.e., not the same as the Initial Term Loans or any other then existing Tranche of Term Loans) unless the
requirements of Section 2.14(c) are satisfied), (viii) all Incremental Term Loans (and all interest, fees and other amounts payable thereon) shall be Obligations under this Agreement and the other applicable Credit Documents and shall be
secured by the Security Documents, and guaranteed under the Subsidiaries Guaranty, on a pari passu basis with all other Obligations secured by the Security Documents and guaranteed under the Subsidiaries Guaranty, (ix) each Lender (including
any Eligible Transferee who will become a Lender) agreeing to provide an Incremental Term Loan Commitment pursuant to an Incremental Term Loan Commitment Agreement shall, subject to the satisfaction of the relevant 

  

 -52- 

 
conditions set forth in this Agreement, make Incremental Term Loans under the Tranche specified in such Incremental Term Loan Commitment Agreement as
provided in Section 2.01(b) and such Incremental Term Loans shall thereafter be deemed to be Incremental Term Loans under such Tranche for all purposes of this Agreement and the other applicable Credit Documents and (x) all actions taken
by the Borrower pursuant to this Section 2.14 shall be done in coordination with the Administrative Agent. 
 (b) In connection with any
provision of Incremental Term Loan Commitments pursuant to this Section 2.14, (i) the Borrower, the Administrative Agent and each such Lender or other Eligible Transferee reasonably acceptable to the Administrative Agent (each, an
“Incremental Term Loan Lender”) which agrees to provide an Incremental Term Loan Commitment shall execute and deliver to the Administrative Agent an Incremental Term Loan Commitment Agreement substantially in the form of Exhibit K
(appropriately completed) (each, an “Incremental Term Loan Commitment Agreement”), with the effectiveness of such Incremental Term Loan Lender’s Incremental Term Loan Commitment to occur upon delivery of such Incremental Term
Loan Commitment Agreement to the Administrative Agent, the payment of any fees required in connection therewith (including, without limitation, any agreed upon up-front or arrangement fees owing to the Administrative Agent) and the satisfaction of
the other terms and conditions described in this Section 2.14 and in the respective Incremental Term Loan Commitment Agreement, and (ii) the Borrower shall deliver to the Administrative Agent (x) an opinion or opinions, in form and
substance reasonably satisfactory to the Administrative Agent, from counsel to the Borrower reasonably satisfactory to the Administrative Agent and dated the applicable Incremental Term Loan Borrowing Date, covering such matters relating to the
provision of the Incremental Term Loan Commitments as may be reasonably requested by the Administrative Agent, (y) a solvency certificate from the Chief Financial Officer of the Borrower, dated the applicable Incremental Term Loan Borrowing
Date, substantially in the form of Exhibit J (with appropriate modifications that are reasonably acceptable to the Administrative Agent to reflect the Incremental Term Loans and any related transactions to occur on such date) and (z) such other
officers’ certificates, board of director resolutions and evidence of good standing as the Administrative Agent shall reasonably request. The Administrative Agent shall promptly notify each Lender as to the effectiveness of each Incremental
Term Loan Commitment Agreement, and at such time (A) Schedule I shall be deemed modified to reflect the Incremental Term Loan Commitments of such Incremental Term Loan Lenders and (B) to the extent requested by any Incremental Term Loan
Lender, an appropriate Incremental Term Note will be issued at the Borrower’s expense to such Incremental Term Loan Lender, to be in conformity with the requirements of Section 2.05 (with appropriate modification) to the extent needed to
reflect the new Incremental Term Loans made by such Incremental Term Loan Lender.
 (c) Notwithstanding anything to the contrary contained
above in this Section 2.14, the Incremental Term Loan Commitments provided by an Incremental Term Loan Lender or Incremental Term Loan Lenders, as the case may be, pursuant to each Incremental Term Loan Commitment Agreement shall constitute a
new Tranche, which shall be separate and distinct from the existing Tranches pursuant to this Agreement (with a designation which may be made in letters (i.e., A, B, C, etc.), numbers (1, 2, 3, etc.) or a combination thereof (i.e., A-1, A-2,
A-3, B-1, B-2, B-3, C-1, C-2, C-3, etc.), provided that, with the consent of the Administrative Agent, the parties to a given Incremental Term Loan Commitment Agreement may specify therein that 

  

 -53- 

 
the respective Incremental Term Loans made pursuant thereto shall constitute part of, and be added to, a then outstanding Tranche of Term Loans so long as
the following requirements are satisfied: 
 (i) the Incremental Term Loans to be made pursuant to such Incremental Term Loan
Commitment Agreement shall have the same Maturity Date and shall have the same Applicable Margins as the Tranche of Term Loans to which the new Incremental Term Loans are being added; 
 (ii) the new Incremental Term Loans to be made pursuant to such Incremental Term Loan Commitment Agreement shall have the same Scheduled
Repayment Dates as then remain with respect to the Tranche of Term Loans to which such new Incremental Term Loans are being added, with the amount of each Scheduled Repayment applicable to such new Incremental Term Loans to be the same (on a
proportionate basis) as was theretofore applicable to the Tranche of Term Loans to which such new Incremental Term Loans are being added, thereby increasing the amount of each then remaining Scheduled Repayment of the respective Tranche of Term
Loans proportionately; and 
 (iii) on the date of the making of such new Incremental Term Loans, and notwithstanding anything
to the contrary set forth in Section 2.09, such new Incremental Term Loans shall be added to (and form part of) each Borrowing of outstanding Term Loans of the respective Tranche on a pro rata basis (based on the relative sizes of the various
outstanding Borrowings), so that each Lender will participate proportionately in each then outstanding Borrowing of Term Loans of the respective Tranche. 
 To the extent the provisions of preceding clause (iii) require that Lenders making new Incremental Term Loans add such Incremental Term Loans to the then outstanding Borrowings of Eurodollar Loans of the respective Tranche of Term
Loans, it is acknowledged that the effect thereof may result in such new Incremental Term Loans having short Interest Periods (i.e., an Interest Period that began during an Interest Period then applicable to outstanding Eurodollar Loans of
the respective Tranche and which will end on the last day of such Interest Period). In connection therewith, the Borrower hereby agrees to compensate the Lenders making the new Incremental Term Loans of the respective Tranche for funding Eurodollar
Loans during an existing Interest Period on such basis as may be reasonably determined by the respective Lenders to compensate them for funding the various Incremental Term Loans during an existing Interest Period (rather than at the beginning of
the respective Interest Period, based upon rates then applicable thereto). All determinations by any Lender pursuant to the immediately preceding sentence shall, absent manifest error, be final and conclusive and binding on all parties hereto.

 SECTION 3. Letters of Credit. 
 3.01. Letters of Credit. (a) Subject to and upon the terms and conditions set forth herein, the Borrower may request that an Issuing Lender issue, at any time and from time to time on and after the Initial Borrowing Date and
prior to the 30th day prior to the Revolving Loan Maturity Date, for the account of the Borrower and for the benefit of (x) any holder (or any trustee, agent or other similar representative for any such holders) of L/C Supportable Obligations,
an irrevocable standby letter of credit, in a form customarily used by such Issuing 

  

 -54- 

 
Lender or in such other form as is reasonably acceptable to such Issuing Lender, and (y) sellers of goods to the Borrower or any of its Subsidiaries, an
irrevocable trade letter of credit, in a form customarily used by such Issuing Lender or in such other form as has been approved by such Issuing Lender (each letter of credit issued pursuant to this Section 3.01(a), together with each letter of
credit described in the immediately succeeding sentence, a “Letter of Credit”). It is hereby acknowledged and agreed that each of the letters of credit described in Part A of Schedule II (the “Existing Inside Letters of
Credit”), which were issued under the Existing First-Lien Credit Agreement and remain outstanding on the Initial Borrowing Date, shall constitute a “Letter of Credit” for all purposes of this Agreement and shall be deemed issued
under this Agreement on the Initial Borrowing Date. All Letters of Credit shall be denominated in Dollars and shall be issued on a sight basis only. 
 (b) Subject to and upon the terms and conditions set forth herein, each Issuing Lender agrees that it will, at any time and from time to time on and after the Initial Borrowing Date and prior to the 30th day prior to
the Revolving Loan Maturity Date, following its receipt of the respective Letter of Credit Request, issue for the account of the Borrower, one or more Letters of Credit as are permitted to remain outstanding hereunder without giving rise to a
Default or an Event of Default, provided that no Issuing Lender shall be under any obligation to issue any Letter of Credit of the types described above if at the time of such issuance: 
 (i) any order, judgment or decree of any Governmental Authority or arbitrator shall purport by its terms to enjoin or restrain such
Issuing Lender from issuing such Letter of Credit or any requirement of law applicable to such Issuing Lender or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such Issuing
Lender shall prohibit, or request that such Issuing Lender refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such Issuing Lender with respect to such Letter of Credit any
restriction or reserve or capital requirement (for which such Issuing Lender is not otherwise compensated hereunder) not in effect with respect to such Issuing Lender on the date hereof, or any unreimbursed loss, cost or expense which was not
applicable or in effect with respect to such Issuing Lender as of the date hereof and which such Issuing Lender reasonably and in good faith deems material to it; or 
 (ii) such Issuing Lender shall have received from the Borrower, any other Credit Party or the Required Lenders prior to the issuance of
such Letter of Credit notice of the type described in the second sentence of Section 3.03(b). 
 3.02. Maximum Letter of Credit
Outstandings; Final Maturities. Notwithstanding anything to the contrary contained in this Agreement, (i) no Letter of Credit shall be issued the Stated Amount of which, when added to the Letter of Credit Outstandings (exclusive of Unpaid
Drawings which are repaid on the date of, and prior to the issuance of, the respective Letter of Credit) at such time would exceed either (x) the L/C Sublimit or (y) when added to the sum of (I) the aggregate principal amount of all
Revolving Loans then outstanding and (II) the aggregate principal amount of all Swingline Loans then outstanding, an amount equal to the Total Revolving Loan Commitment at such time, and (ii) each Letter of Credit shall by its terms
terminate (x) in the case of standby Letters of Credit, on or before the earlier of (A) the date which occurs 12 months after the date of the issuance thereof (although any such 

  

 -55- 

 
standby Letter of Credit may be extendible for successive periods of up to 12 months, but, in each case, not beyond the tenth Business Day prior to the
Revolving Loan Maturity Date, on terms reasonably acceptable to the respective Issuing Lender) and (B) 10 Business Days prior to the Revolving Loan Maturity Date, and (y) in the case of trade Letters of Credit, on or before the
earlier of (A) the date which occurs 180 days after the date of issuance thereof and (B) 10 Business Days prior to the Revolving Loan Maturity Date. 
 3.03. Letter of Credit Requests; Minimum Stated Amount. (a) Whenever the Borrower desires that a Letter of Credit be issued for its account, the Borrower shall give the Administrative Agent and the
respective Issuing Lender at least five Business Days’ (or such shorter period as is acceptable to such Issuing Lender) written notice thereof (including by way of facsimile). Each notice shall be in the form of Exhibit C, appropriately
completed (each, a “Letter of Credit Request”). 
 (b) The making of each Letter of Credit Request shall be deemed to be a
representation and warranty by the Borrower to the Lenders that such Letter of Credit may be issued in accordance with, and will not violate the requirements of, Section 3.02. Unless the respective Issuing Lender has received notice from the
Borrower, any other Credit Party or the Required Lenders before it issues a Letter of Credit that one or more of the conditions specified in Section 6 or 7 are not then satisfied, or that the issuance of such Letter of Credit would violate
Section 3.02, then such Issuing Lender shall, subject to the terms and conditions of this Agreement, issue the requested Letter of Credit for the account of the Borrower in accordance with such Issuing Lender’s usual and customary
practices. Upon the issuance of or modification or amendment to any standby Letter of Credit, each Issuing Lender shall promptly notify the Borrower and the Administrative Agent, in writing, of such issuance, modification or amendment and such
notice shall be accompanied by a copy of such Letter of Credit or the respective modification or amendment thereto, as the case may be. Promptly after receipt of such notice, the Administrative Agent shall notify the Participants, in writing, of
such issuance, modification or amendment. On the first Business Day of each week, each Issuing Lender shall furnish the Administrative Agent with a written (including via facsimile) report of the daily aggregate outstandings of Letters of Credit
issued by such Issuing Lender for the immediately preceding week. Notwithstanding anything to the contrary contained in this Agreement, in the event that a Lender Default exists with respect to an RL Lender, no Issuing Lender shall be required to
issue any Letter of Credit unless such Issuing Lender has entered into arrangements satisfactory to it and the Borrower to eliminate such Issuing Lender’s risk with respect to the participation in Letters of Credit by the Defaulting Lender or
Lenders, including by cash collateralizing such Defaulting Lender’s or Lenders’ RL Percentage of the Letter of Credit Outstandings. 
 (c) The initial Stated Amount of each Letter of Credit shall not be less than $25,000 or such lesser amount as is acceptable to the respective Issuing Lender. 
 3.04. Letter of Credit Participations. (a) Immediately upon the issuance by an Issuing Lender of any Letter of Credit, such Issuing Lender shall be deemed to have sold and transferred to each RL
Lender, and each such RL Lender (in its capacity under this Section 3.04, a “Participant”) shall be deemed irrevocably and unconditionally to have purchased and received from such Issuing Lender, without recourse or warranty,
an undivided interest and participation, 
  

 -56- 

 
to the extent of such Participant’s RL Percentage, in such Letter of Credit, each drawing or payment made thereunder and the obligations of the Borrower
under this Agreement with respect thereto, and any security therefor or guaranty pertaining thereto. Upon any change in the Revolving Loan Commitments or RL Percentages of the Lenders pursuant to Section 2.13 or 13.04(b), it is hereby agreed
that, with respect to all outstanding Letters of Credit and Unpaid Drawings relating thereto, there shall be an automatic adjustment to the participations pursuant to this Section 3.04 to reflect the new RL Percentages of the assignor and
assignee Lender, as the case may be. 
 (b) In determining whether to pay under any Letter of Credit, no Issuing Lender shall have any
obligation relative to the other Lenders other than to confirm that any documents required to be delivered under such Letter of Credit appear to have been delivered and that they appear to substantially comply on their face with the requirements of
such Letter of Credit. Any action taken or omitted to be taken by an Issuing Lender under or in connection with any Letter of Credit issued by it shall not create for such Issuing Lender any resulting liability to the Borrower, any other Credit
Party, any Lender or any other Person unless such action is taken or omitted to be taken with gross negligence or willful misconduct on the part of such Issuing Lender (as determined by a court of competent jurisdiction in a final and non-appealable
decision). 
 (c) In the event that an Issuing Lender makes any payment under any Letter of Credit issued by it and the Borrower shall not
have reimbursed such amount in full to such Issuing Lender pursuant to Section 3.05(a), such Issuing Lender shall promptly notify the Administrative Agent, which shall promptly notify each Participant of such failure, and each Participant shall
promptly and unconditionally pay to such Issuing Lender the amount of such Participant’s RL Percentage of such unreimbursed payment in Dollars and in same day funds. If the Administrative Agent so notifies, prior to 12:00 Noon (New York City
time) on any Business Day, any Participant required to fund a payment under a Letter of Credit, such Participant shall make available to the respective Issuing Lender in Dollars such Participant’s RL Percentage of the amount of such payment on
such Business Day in same day funds (and, to the extent that such notice is given after 12:00 Noon (New York City time) on any Business Day, such amount will be made available by each Participant on the immediately succeeding Business Day). If and
to the extent such Participant shall not have so made its RL Percentage of the amount of such payment available to respective Issuing Lender, such Participant agrees to pay to such Issuing Lender, forthwith on demand such amount, together with
interest thereon, for each day from such date until the date such amount is paid to such Issuing Lender at the overnight Federal Funds Rate for the first three days and at the interest rate applicable to Revolving Loans that are maintained as Base
Rate Loans for each day thereafter. The failure of any Participant to make available to an Issuing Lender its RL Percentage of any payment under any Letter of Credit issued by such Issuing Lender shall not relieve any other Participant of its
obligation hereunder to make available to such Issuing Lender its RL Percentage of any payment under any Letter of Credit on the date required, as specified above, but no Participant shall be responsible for the failure of any other Participant to
make available to such Issuing Lender such other Participant’s RL Percentage of any such payment. 
 (d) Whenever an Issuing Lender
receives a payment of a reimbursement obligation as to which it has received any payments from the Participants pursuant to clause 

  

 -57- 

 
(c) above, such Issuing Lender shall pay to each such Participant which has paid its RL Percentage thereof, in Dollars and in same day funds, an amount
equal to such Participant’s share (based upon the proportionate aggregate amount originally funded by such Participant to the aggregate amount funded by all Participants) of the principal amount of such reimbursement obligation and interest
thereon accruing after the purchase of the respective participations. 
 (e) Upon the request of any Participant, each Issuing Lender shall
furnish to such Participant copies of any standby Letter of Credit issued by it and such other documentation as may reasonably be requested by such Participant. 
 (f) The obligations of the Participants to make payments to each Issuing Lender with respect to Letters of Credit shall be irrevocable and not subject to any qualification or exception whatsoever and shall be made in
accordance with the terms and conditions of this Agreement under all circumstances, including, without limitation, any of the following circumstances: 
 (i) any lack of validity or enforceability of this Agreement or any of the other Credit Documents; 
 (ii) the existence of any claim, setoff, defense or other right which the Borrower or any of its Subsidiaries may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for
whom any such transferee may be acting), the Administrative Agent, any Participant, or any other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including
any underlying transaction between the Borrower or any Subsidiary of the Borrower and the beneficiary named in any such Letter of Credit); 
 (iii) any draft, certificate or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in
any respect; 
 (iv) the surrender or impairment of any security for the performance or observance of any of the terms of any
of the Credit Documents; or 
 (v) the occurrence of any Default or Event of Default. 
 3.05. Agreement to Repay Letter of Credit Drawings. (a) The Borrower agrees to reimburse each Issuing Lender, by making payment to the
Administrative Agent in immediately available funds at the Payment Office, for any payment or disbursement made by such Issuing Lender under any Letter of Credit issued by it (each such amount, so paid until reimbursed by the Borrower, an
“Unpaid Drawing”), not later than one Business Day following receipt by the Borrower of notice of such payment or disbursement (provided that no such notice shall be required to be given if a Default or an Event of Default
under Section 11.05 shall have occurred and be continuing, in which case the Unpaid Drawing shall be due and payable immediately without presentment, demand, protest or notice of any kind (all of which are hereby waived by the Borrower)), with
interest on the amount so paid or disbursed by such Issuing Lender, to the extent not reimbursed prior to 12:00 Noon (New York City time) on the date of 

  

 -58- 

 
such payment or disbursement, from and including the date paid or disbursed to but excluding the date such Issuing Lender was reimbursed by the Borrower
therefor at a rate per annum equal to the Base Rate as in effect from time to time plus the Applicable Margin as in effect from time to time for Revolving Loans that are maintained as Base Rate Loans, provided, however, to the
extent such amounts are not reimbursed prior to 12:00 Noon (New York City time) on the third Business Day following the receipt by the Borrower of notice of such payment or disbursement or following the occurrence of a Default or an Event of Default
under Section 11.05, interest shall thereafter accrue on the amounts so paid or disbursed by such Issuing Lender (and until reimbursed by the Borrower) at a rate per annum equal to the Base Rate as in effect from time to time plus the
Applicable Margin for Revolving Loans that are maintained as Base Rate Loans as in effect from time to time plus 2%, with such interest to be payable on demand. Each Issuing Lender shall give the Borrower prompt written notice of each Drawing
under any Letter of Credit issued by it, provided that the failure to give any such notice shall in no way affect, impair or diminish the Borrower’s obligations hereunder. 
 (b) The obligations of the Borrower under this Section 3.05 to reimburse each Issuing Lender with respect to drafts, demands and other presentations
for payment under Letters of Credit issued by it (each, a “Drawing”) (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or
defense to payment which the Borrower or any of its Subsidiaries may have or have had against any Lender (including in its capacity as an Issuing Lender or as a Participant), including, without limitation, any defense based upon the failure of any
Drawing under a Letter of Credit to conform to the terms of the Letter of Credit or any nonapplication or misapplication by the beneficiary of the proceeds of such Drawing; provided, however, that the Borrower shall not be obligated to
reimburse any Issuing Lender for any wrongful payment made by such Issuing Lender under a Letter of Credit issued by it as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such Issuing Lender (as
determined by a court of competent jurisdiction in a final and non-appealable decision). 
 3.06. Increased Costs. If at any time
after the Effective Date, the introduction of or any change in any applicable law, rule, regulation, order, guideline or request or in the interpretation or administration thereof by the NAIC or any Governmental Authority charged with the
interpretation or administration thereof, or compliance by any Issuing Lender or any Participant with any request or directive by the NAIC or by any such Governmental Authority (whether or not having the force of law), shall either (i) impose,
modify or make applicable any reserve, deposit, capital adequacy or similar requirement against letters of credit issued by any Issuing Lender or participated in by any Participant, or (ii) impose on any Issuing Lender or any Participant any
other conditions relating, directly or indirectly, to this Agreement or any Letter of Credit; and the result of any of the foregoing is to increase the cost to any Issuing Lender or any Participant of issuing, maintaining or participating in any
Letter of Credit, or reduce the amount of any sum received or receivable by any Issuing Lender or any Participant hereunder or reduce the rate of return on its capital with respect to Letters of Credit (except for changes in the rate of tax on, or
determined by reference to, the net income or net profits of such Issuing Lender or such Participant pursuant to the laws of the jurisdiction in which it is organized or in which its principal office or applicable lending office is located or any
subdivision thereof or therein), then, upon the delivery of the certificate referred to below to the Borrower by any Issuing Lender or any Participant (a copy of which certificate shall be sent by such Issuing Lender or such 

  

 -59- 

 
Participant to the Administrative Agent), the Borrower agrees to pay to such Issuing Lender or such Participant such additional amount or amounts as will
compensate such Issuing Lender or such Participant for such increased cost or reduction in the amount receivable or reduction on the rate of return on its capital. Any Issuing Lender or any Participant, upon determining that any additional amounts
will be payable to it pursuant to this Section 3.06, will give prompt written notice thereof to the Borrower, which notice shall include a certificate submitted to the Borrower by such Issuing Lender or such Participant (a copy of which
certificate shall be sent by such Issuing Lender or such Participant to the Administrative Agent), setting forth in reasonable detail the basis for the calculation of such additional amount or amounts necessary to compensate such Issuing Lender or
such Participant. The certificate required to be delivered pursuant to this Section 3.06 shall, absent manifest error, be final and conclusive and binding on the Borrower. 
 SECTION 4. Commitment Commission; Fees; Reductions of Commitment. 
 4.01. Fees. (a) The Borrower agrees to pay to the Administrative Agent for
distribution to each Non-Defaulting RL Lender a commitment commission (the “Commitment Commission”) for the period from and including the Effective Date to and including the Revolving Loan Maturity Date (or such earlier date on
which the Total Revolving Loan Commitment has been terminated) computed at a rate per annum equal to  1/2 of 1%
of the Unutilized Revolving Loan Commitment of such Non-Defaulting RL Lender as in effect from time to time. The accrued Commitment Commission shall be due and payable quarterly in arrears on each Quarterly Payment Date and on the date upon which
the Total Revolving Loan Commitment is terminated. 
 (b) The Borrower agrees to pay to the Administrative Agent for distribution to
each RL Lender (based on each such RL Lender’s respective RL Percentage) a fee in respect of each Letter of Credit (the “Letter of Credit Fee”) for the period from and including the date of issuance of such Letter of Credit to
and including the date of termination or expiration of such Letter of Credit, computed at a rate per annum equal to the Applicable Margin as in effect from time to time during such period with respect to Revolving Loans that are maintained as
Eurodollar Loans on the daily Stated Amount of each such Letter of Credit. Accrued Letter of Credit Fees shall be due and payable quarterly in arrears on each Quarterly Payment Date and on the first day on or after the termination of the Total
Revolving Loan Commitment upon which no Letters of Credit remain outstanding. 
 (c) The Borrower agrees to pay to each Issuing Lender, for
its own account, a facing fee in respect of each Letter of Credit issued by it (the “Facing Fee”) for the period from and including the date of issuance of such Letter of Credit to and including the date of termination or expiration
of such Letter of Credit, computed at a rate per annum equal to 1/4 of 1% on the daily Stated Amount of such Letter of Credit, provided that in any event the minimum amount of Facing Fees payable in any twelve-month period for each Letter of
Credit shall be not less than $500, it being agreed that, on the day of issuance of any Letter of Credit and on each anniversary thereof prior to the termination or expiration of such Letter of Credit, if $500 will exceed the amount of Facing Fees
that will accrue with respect to such Letter of Credit for the immediately succeeding twelve-month period, the full $500 shall be payable on the date of issuance of such Letter of Credit and on each such anniversary thereof. Except as otherwise
provided in the proviso to the immediately preceding sentence, accrued Facing Fees shall be due 

  

 -60- 

 
and payable quarterly in arrears on each Quarterly Payment Date and upon the first day on or after the termination of the Total Revolving Loan Commitment
upon which no Letters of Credit remain outstanding. 
 (d) The Borrower agrees to pay to each Issuing Lender, for its own account, upon each
payment under, issuance of, or amendment to, any Letter of Credit issued by it, such amount as shall at the time of such event be the administrative charge and the reasonable expenses which such Issuing Lender is generally imposing in connection
with such occurrence with respect to letters of credit. 
 (e) The Borrower agrees to pay to the Administrative Agent such fees as may be
agreed to in writing from time to time by the Borrower, PAETEC Parent, US LEC or any of their respective Subsidiaries and the Administrative Agent. 
 (f) The Borrower shall pay to the Administrative Agent for distribution to the respective Incremental Term Loan Lenders such fees and other amounts, if any, as are specified in each Incremental Term Loan Commitment Agreement, with such fees
and other amounts, if any, to be payable on the respective Incremental Term Loan Borrowing Date. 
 4.02. Voluntary Termination of
Unutilized Revolving Loan Commitments. (a) Upon at least one Business Day’s prior written notice to the Administrative Agent at the Notice Office (which notice the Administrative Agent shall promptly transmit to each of the Lenders),
the Borrower shall have the right, at any time or from time to time, without premium or penalty to terminate the Total Unutilized Revolving Loan Commitment in whole, or reduce it in part, pursuant to this Section 4.02(a), in an integral
multiple of $1,000,000 in the case of partial reductions to the Total Unutilized Revolving Loan Commitment, provided that each such reduction shall apply proportionately to permanently reduce the Revolving Loan Commitment of each RL Lender.

 (b) In the event of certain refusals by a Lender to consent to certain proposed changes, waivers, discharges or terminations with respect
to this Agreement which have been approved by the Required Lenders as (and to the extent) provided in Section 13.12(b), the Borrower shall have the right, subject to obtaining the consents required by Section 13.12(b), upon five Business
Days’ prior written notice to the Administrative Agent at the Notice Office (which notice the Administrative Agent shall promptly transmit to each of the Lenders), to terminate the entire Revolving Loan Commitment of such Lender, so long as all
Loans, together with accrued and unpaid interest, Fees and all other amounts, owing to such Lender (including all amounts, if any, owing pursuant to Section 2.11 but excluding the payment of amounts owing in respect of Loans of any Tranche
maintained by such Lender, if such Loans are not being repaid pursuant to Section 13.12(b)) are repaid concurrently with the effectiveness of such termination (at which time Schedule I shall be deemed modified to reflect such changed amounts)
and such Lender’s RL Percentage of all outstanding Letters of Credit is cash collateralized in a manner satisfactory to the Administrative Agent and the respective Issuing Lenders, and at such time, unless the respective Lender continues to
have outstanding Term Loans hereunder, such Lender shall no longer constitute a “Lender” for purposes of this Agreement, except with respect to indemnifications under this Agreement (including, without 

  

 -61- 

 
limitation, Sections 2.10, 2.11, 3.06, 5.04, 12.06, 13.01 and 13.06), which shall survive as to such repaid Lender. 
 4.03. Mandatory Reduction of Commitments. (a) The Total Commitment (and the Commitment of each Lender) shall terminate in its entirety on
April 30, 2007, unless the Initial Borrowing Date has occurred on or prior to such date. 
 (b) In addition to any other mandatory
commitment reductions pursuant to this Section 4.03, the Total Initial Term Loan Commitment (and the Initial Term Loan Commitment of each Lender) shall terminate in its entirety on the Initial Borrowing Date (after giving effect to the
incurrence of Initial Term Loans on such date). 
 (c) In addition to any other mandatory commitment reductions pursuant to this
Section 4.03, the Total Incremental Term Loan Commitment (and the Incremental Term Loan Commitment of each Lender) under each Tranche of Incremental Term Loans pursuant to the applicable Incremental Term Loan Commitment Agreement shall
terminate in its entirety on the Incremental Term Loan Borrowing Date for such Tranche of Incremental Term Loans (after giving effect to the incurrence of Incremental Term Loans of such Tranche on such date). 
 (d) In addition to any other mandatory commitment reductions pursuant to this Section 4.03, the Total Revolving Loan Commitment shall terminate in
its entirety upon the earlier of (i) the Revolving Loan Maturity Date and (ii) unless the Required Lenders otherwise agree in writing, the date on which a Change of Control occurs. 
 (e) In addition to any other mandatory commitment reductions pursuant to this Section 4.03, the Total Revolving Loan Commitment shall be permanently
reduced from time to time to the extent required by Section 5.02(g). 
 (f) Each reduction to, or termination of, the Total Revolving
Loan Commitment pursuant to this Section 4.03 shall be applied to proportionately reduce or terminate, as the case may be, the Revolving Loan Commitment of each Lender with a Revolving Loan Commitment. 
 SECTION 5. Prepayments; Payments; Taxes. 
 5.01. Voluntary Prepayments. (a) The Borrower shall have the right to prepay the Loans, without premium or penalty, in whole or in part at any time and from time to time on the following terms and conditions: (i) the
Borrower shall give the Administrative Agent prior to 12:00 Noon (New York City time) at the Notice Office (x) at least one Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) of its intent to prepay
Base Rate Loans (or same day notice in the case of a prepayment of Swingline Loans) and (y) at least three Business Days’ prior written notice (or telephonic notice promptly confirmed in writing) of its intent to prepay Eurodollar Loans,
which notice (in each case) shall specify whether Initial Term Loans, Incremental Term Loans under a given Tranche, Revolving Loans or Swingline Loans shall be prepaid, the amount of such prepayment and the Types of Loans to be prepaid and, in the
case of Eurodollar Loans, the specific Borrowing or Borrowings pursuant to which such Eurodollar Loans were made, and which notice the Administrative Agent shall, except in the case of a prepayment of Swingline Loans, promptly transmit to each of
the Lenders; (ii) (x)

  

 -62- 

 
each partial prepayment of Term Loans pursuant to this Section 5.01(a) shall be in an aggregate principal amount of at least $1,000,000 (or such lesser
amount as is acceptable to the Administrative Agent in any given case), (y) each partial prepayment of Revolving Loans pursuant to this Section 5.01(a) shall be in an aggregate principal amount of at least $250,000 (or such lesser amount
as is acceptable to the Administrative Agent) and (z) each partial prepayment of Swingline Loans pursuant to this Section 5.01(a) shall be in an aggregate principal amount of at least $100,000 (or such lesser amount as is acceptable to the
Administrative Agent in any given case), provided that if any partial prepayment of Eurodollar Loans made pursuant to any Borrowing shall reduce the outstanding principal amount of Eurodollar Loans made pursuant to such Borrowing to an amount
less than the Minimum Borrowing Amount applicable thereto, then such Borrowing may not be continued as a Borrowing of Eurodollar Loans (and such Borrowing shall automatically be converted into a Borrowing of Base Rate Loans) and any election of an
Interest Period with respect thereto given by the Borrower shall have no force or effect; (iii) each prepayment pursuant to this Section 5.01(a) in respect of any Loans made pursuant to a Borrowing shall be applied pro rata
among such Loans, provided that at the Borrower’s election in connection with any prepayment of Revolving Loans pursuant to this Section 5.01(a), such prepayment shall not, so long as no Default or Event of Default then exists, be
applied to any Revolving Loan of a Defaulting Lender; (iv) each prepayment in respect of any Tranche of Term Loans made pursuant to this Section 5.01(a) shall be allocated among each of the outstanding Tranches of Term Loans on a
pro rata basis, with each Tranche of Term Loans to be allocated its Term Loan Percentage of the amount of such prepayment; and (v) each prepayment of any Tranche of Term Loans pursuant to this Section 5.01(a) shall reduce the
then remaining Scheduled Repayments of such Tranche on a pro rata basis (based upon the then remaining amounts of such Scheduled Repayments of such Tranche). 
 (b) In the event of certain refusals by a Lender to consent to certain proposed changes, waivers, discharges or terminations with respect to this
Agreement which have been approved by the Required Lenders as (and to the extent) provided in Section 13.12(b), the Borrower may, upon five Business Days’ prior written notice to the Administrative Agent at the Notice Office (which notice
the Administrative Agent shall promptly transmit to each of the Lenders), repay all Loans of such Lender (including all amounts, if any, owing pursuant to Section 2.11), together with accrued and unpaid interest, Fees and all other amounts then
owing to such Lender (or owing to such Lender with respect to each Tranche which gave rise to the need to obtain such Lender’s individual consent) in accordance with, and subject to the requirements of, such Section 13.12(b), so long as
(A) in the case of the repayment of Revolving Loans of any Lender pursuant to this clause (b), (x) the Revolving Loan Commitment of such Lender is terminated concurrently with such repayment pursuant to Section 4.02(b) (at which time
Schedule I shall be deemed modified to reflect the changed Revolving Loan Commitments) and (y) such Lender’s RL Percentage of all outstanding Letters of Credit is cash collateralized in a manner satisfactory to the Administrative Agent and
the respective Issuing Lenders and (B) the consents, if any, required by Section 13.12(b) in connection with the repayment pursuant to this clause (b) shall have been obtained. Each prepayment of any Tranche of Term Loans pursuant to
this Section 5.01(b) shall reduce the then remaining Scheduled Repayments of such Tranche of Term Loans on a pro rata basis (based upon the then remaining principal amount of each such Scheduled Repayment of such Tranche after
giving effect to all prior reductions thereto). 
  

 -63- 

 5.02. Mandatory Repayment. (a) On any day on which the sum of (I) the aggregate
outstanding principal amount of all Revolving Loans (after giving effect to all other repayments thereof on such date), (II) the aggregate outstanding principal amount of all Swingline Loans (after giving effect to all other repayments thereof on
such date) and (III) the aggregate amount of all Letter of Credit Outstandings, exceeds the Total Revolving Loan Commitment at such time, the Borrower shall prepay on such day the principal of Swingline Loans and, after all Swingline Loans have been
repaid in full or if no Swingline Loans are outstanding, Revolving Loans in an amount equal to such excess. If, after giving effect to the prepayment of all outstanding Swingline Loans and Revolving Loans, the aggregate amount of the Letter of
Credit Outstandings exceeds the Total Revolving Loan Commitment at such time, the Borrower shall pay to the Administrative Agent at the Payment Office on such day an amount of cash and/or Cash Equivalents equal to the amount of such excess (up to a
maximum amount equal to the Letter of Credit Outstandings at such time), such cash and/or Cash Equivalents to be held as security for all Obligations of the Borrower to the Issuing Lenders and the Lenders hereunder in a cash collateral account to be
established by the Administrative Agent. 
 (b) (i) In addition to any other mandatory repayments pursuant to this Section 5.02, on each
date set forth below (each, a “Scheduled Initial Term Loan Repayment Date”), the Borrower shall be required to repay that principal amount of Initial Term Loans, to the extent then outstanding, as is set forth opposite each such
date below (each such repayment, as the same may be (x) reduced as provided in Section 5.01(a), 5.01(b) or 5.02(g) or (y) increased as provided in Section 2.14(c), a “Scheduled Initial Term Loan Repayment”):

 (ii) In addition to any other mandatory repayments pursuant to this Section 5.02, the
Borrower shall be required to make, with respect to each Tranche of Incremental Term Loans, to the extent then outstanding, scheduled amortization payments of such Tranche of Incremental Term Loans on the dates and in the principal amounts set forth
in the respective Incremental Term Loan Commitment Agreement (each such date, a “Scheduled Incremental Term Loan Repayment Date”, and each such repayment, as the same may be (x) reduced as provided in Section 5.01(a),
5.01(b) or 5.02(g) or (y) increased as provided in Section 2.14(c), a “Scheduled Incremental Term Loan Repayment”). 
 (c) In addition to any other mandatory repayments or commitment reductions pursuant to this Section 5.02, on each date on or after the Initial Borrowing Date upon which the Borrower or any of its Subsidiaries receives any cash proceeds
from any issuance or incurrence by the Borrower or any of its Subsidiaries of Indebtedness (other than Indebtedness permitted to be issued or incurred pursuant to Section 10.04 as such Section is in effect on the Effective Date), an amount
equal to 100% of the Net Cash Proceeds of the respective issuance or incurrence of Indebtedness shall be applied on such date as a mandatory repayment and/or commitment reduction in accordance with the requirements of Sections 5.02(g) and (h).

 (d) In addition to any other mandatory repayments or commitment reductions pursuant to this Section 5.02, on each date on or after
the Initial Borrowing Date upon which the Borrower or any of its Subsidiaries receives any cash proceeds from any Asset Sale, an amount equal to 100% of the Net Sale Proceeds therefrom shall be applied on such date as a mandatory repayment and/or
commitment reduction in accordance with the requirements of Sections 5.02(g) and (h); provided, however, that with respect to no more than $7,500,000 in the aggregate of such Net Sale Proceeds received by the Borrower and/or its
Subsidiaries in any fiscal year of the Borrower, such Net Sale Proceeds shall not be required to be so applied on such date so long as no Default or Event of Default then exists and such Net Sale Proceeds shall be used to purchase assets (other than
inventory and working capital) used or to be used in the businesses permitted pursuant to Section 10.12, or in the case of the Net Cash Proceeds from the sale of the Existing US LEC Minority Interest, shall be invested in the businesses
permitted pursuant to Section 10.12, in either case within 365 days following the date of such Asset Sale, and provided further, that if all or any portion of such Net Sale Proceeds not required to be so applied as provided above
in this Section 5.02(d) are not so used within such 365-day period, or such earlier date, if any, as the Borrower or the relevant Subsidiary determines not to reinvest the Net Sale Proceeds from such Asset Sale as set forth above, such
remaining portion shall be applied on the last day of such 365-day period as a mandatory repayment and/or commitment reduction as provided above in this Section 5.02(d) (without giving effect to the immediately preceding proviso). 

 

 -66- 

 (e) In addition to any other mandatory repayments or commitment reductions pursuant to this
Section 5.02, on each Excess Cash Payment Date, an amount equal to the Applicable Excess Cash Flow Prepayment Percentage of the Excess Cash Flow for the related Excess Cash Payment Period shall be applied as a mandatory repayment and/or
commitment reduction in accordance with the requirements of Sections 5.02(g) and (h). 
 (f) In addition to any other mandatory repayments or
commitment reductions pursuant to this Section 5.02, on each date on or after the Initial Borrowing Date upon which the Borrower or any of its Subsidiaries receives any cash proceeds from any Recovery Event (other than Recovery Events where the
Net Cash Proceeds therefrom do not exceed $50,000), an amount equal to 100% of the Net Cash Proceeds from such Recovery Event shall be applied on such date as a mandatory repayment and/or commitment reduction in accordance with the requirements of
Sections 5.02(g) and (h); provided, however, that so long as no Default or Event of Default then exists, such Net Cash Proceeds shall not be required to be so applied on such date to the extent that the Borrower has delivered a
certificate to the Administrative Agent on or prior to such date stating that such Net Cash Proceeds shall be (i) used to replace or restore any properties or assets in respect of which such Net Cash Proceeds were paid within 180 days following
the date of the receipt of such Net Cash Proceeds or (ii) contractually committed within 180 days following the date of the receipt of such Net Cash Proceeds to be so used within 270 days following the date of the receipt of such Net Cash
Proceeds (which certificate shall set forth the estimates of the Net Cash Proceeds to be so expended), and provided further, that (x) so long as no Default or Event of Default then exists and to the extent that the amount of such Net
Cash Proceeds equals or exceeds $20,000,000, the amount of such Net Cash Proceeds, together with other cash available to the Borrower and its Subsidiaries and permitted to be spent by them on Capital Expenditures during the relevant period, equals
at least 100% of the cost of replacement or restoration of the properties or assets in respect of which such Net Cash Proceeds were paid as determined by the Borrower and as supported by such information as the Administrative Agent may reasonably
request, then the entire amount of the Net Cash Proceeds from such Recovery Event (and not just the portion thereof in excess of $20,000,000) shall be deposited with the Administrative Agent pursuant to a cash collateral arrangement reasonably
satisfactory to the Administrative Agent whereby such proceeds shall be disbursed to the Borrower or its relevant Subsidiary from time to time as needed to pay or reimburse the Borrower or such Subsidiary for the actual costs incurred by it in
connection with the replacement or restoration of the respective properties or assets (pursuant to such certification requirements as may be reasonably established by the Administrative Agent), although at any time while an Event of Default has
occurred and is continuing, the Required Lenders may direct the Administrative Agent (in which case the Administrative Agent shall, and is hereby authorized by the Borrower to, follow such directions) to apply any or all proceeds then on deposit in
such collateral account in accordance with the requirements of Sections 5.02(g) and (h) and (y) if (I) all or any portion of such Net Cash Proceeds not required to be so applied pursuant to the preceding proviso are not so used within
180 days after the date of the receipt of such Net Cash Proceeds (or contractually committed within such period to be used with 270 days following the date of the receipt of such Net Cash Proceeds), or such earlier date, if any, as the Borrower or
its relevant Subsidiary determines not to reinvest the Net Cash Proceeds relating to such Recovery Event as set forth above, such remaining portion shall be applied on the last day of such 180-day period as a mandatory repayment and/or commitment
reduction as provided above in this Section 5.02(f) (without giving effect to the immediately preceding proviso) and 

  

 -67- 

 
(II) all or any portion of such Net Cash Proceeds are not required to be applied on the last day of such 180-day period referred to in clause (I) of
this proviso because such amount is contractually committed to be used and then subsequent to such date such contract is terminated or expires without such portion being so used or such Net Cash Proceeds are not so reinvested within 270 days
following the date of such Recovery Event, such remaining portion shall be applied on the last day of such 270-day period as a mandatory repayment and/or commitment reduction as provided above in this Section 5.02(f) (without giving effect to
the immediately preceding proviso). 
 (g) Each amount required to be applied pursuant to Sections 5.02(c), (d), (e) and (f) in
accordance with this Section 5.02(g) shall be applied (i) first, to repay the outstanding principal amount of Term Loans and shall be allocated among each Tranche of outstanding Term Loans on a pro rata basis, with
each Tranche of Term Loans to be allocated its Term Loan Percentage of the amount of the respective repayment, and (ii) second, except for amounts required to be applied pursuant to Section 5.02(e), to the extent in excess of the
amounts so required to be applied pursuant to the preceding clause (i), to reduce the Total Revolving Loan Commitment in the manner provided in Sections 4.03(e) and (f) (it being understood and agreed that (x) the amount of any reduction
to the Total Revolving Loan Commitment as provided in immediately preceding clause (ii) shall be deemed to be an application of proceeds for purposes of this Section 5.02(g) even though cash is not actually applied and (y) any cash
received by the Borrower or any of its Subsidiaries will be retained by such Person except to the extent that either (A) such cash is otherwise required to be applied as provided in Section 5.02(a) as a result of any reduction to the Total
Revolving Loan Commitment or (B) a Default or an Event of Default then exists, in which case such cash (after giving effect to any application otherwise required pursuant to preceding sub-clause (A)) shall be deposited with the Administrative
Agent as security for all Obligations of the Borrower to the Lenders hereunder in a cash collateral account to be established by the Administrative Agent)). The amount of each principal repayment of each Tranche of Term Loans made as required by
Sections 5.02(c), (d), (e) and (f) shall be applied to reduce the then remaining Scheduled Repayments of such Tranche of Term Loans on a pro rata basis (based upon the then remaining amounts of such Scheduled Repayments of
the respective Tranche). 
 (h) With respect to each repayment of Loans required by this Section 5.02, the Borrower may designate the
Types of Loans of the respective Tranche which are to be repaid and, in the case of Eurodollar Loans, the specific Borrowing or Borrowings of the respective Tranche pursuant to which such Eurodollar Loans were made, provided that:
(i) repayments of Eurodollar Loans pursuant to this Section 5.02 may only be made on the last day of an Interest Period applicable thereto unless all Eurodollar Loans of the respective Tranche with Interest Periods ending on such date of
required repayment and all Base Rate Loans of the respective Tranche have been paid in full; (ii) if any repayment of Eurodollar Loans made pursuant to a single Borrowing shall reduce the outstanding Eurodollar Loans made pursuant to such
Borrowing to an amount less than the Minimum Borrowing Amount applicable thereto, such Borrowing shall be automatically converted into a Borrowing of Base Rate Loans; and (iii) each repayment of any Loans made pursuant to a Borrowing shall be
applied pro rata among such Loans. In the absence of a designation by the Borrower as described in the preceding sentence, the Administrative Agent shall, subject to the above, make such designation in its sole discretion. 

 

 -68- 

 (i) In addition to any other mandatory repayments pursuant to this Section 5.02, (i) all then
outstanding Loans of a respective Tranche shall be repaid in full on the respective Maturity Date for such Tranche of Loans, and (ii) unless the Required Lenders otherwise agree in writing, all then outstanding Loans shall be repaid in full on
the date on which a Change of Control occurs. 
 5.03. Method and Place of Payment, etc. (a) Except as otherwise specifically provided
herein, all payments under this Agreement and under any Note shall be made to the Administrative Agent for the account of the Lender or Lenders entitled thereto not later than 12:00 Noon (New York City time) on the date when due and shall be made in
Dollars in immediately available funds at the Payment Office. Notwithstanding anything to the contrary contained in this Agreement, whenever any payment to be made under this Agreement or under any Note shall be stated to be due on a day which is
not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest shall be payable at the applicable rate during such extension. 
 (b) Notwithstanding anything to the contrary contained in this Agreement, if it is subsequently determined that the Total Leverage Ratio set forth in any
Quarterly Pricing Certificate delivered to the Administrative Agent is inaccurate for any reason and the result thereof is that the RL Lenders received interest or Letter of Credit Fees for any period at an Applicable Margin that is less than that
which would have been applicable thereto had the Total Leverage Ratio been accurately determined, then the Borrower shall pay to the Administrative Agent for the account of each RL Lender such additional interest and/or Letter of Credit Fees for
such period in an amount equal to the remainder of (x) the amount of interest and/or Letter of Credit Fees to which such RL Lenders would have received had the Total Leverage Ratio been correctly computed minus (y) the amount of
interest and/or Letter of Credit Fees actually paid to such RL Lenders for such period, together with interest on such additional amounts (to the extent permitted by law) for such period at a rate per annum equal to the Base Rate that was in effect
from to time during such period plus the Applicable Margin during such period (reflecting the correct Total Leverage Ratio) for Revolving Loans maintained as Base Rate Loans. Such additional interest and/or Letter of Credit Fees shall be due and
payable within three (3) Business Days after at the Borrower obtains knowledge (including by way of notification thereof from the Administrative Agent or the Required Lenders) that the Total Leverage Ratio was inaccurately computed. Upon the
payment in full of any accrued additional interest and/or Letter of Credit Fees pursuant to this Section 5.03(b), any Default or Event of Default that may have arisen solely as a result of the Quarterly Pricing Certificate miscalculating the
Total Leverage Ratio for purposes of calculating the Applicable Margin (but not for purposes of calculating the Total Leverage Ratio under Section 10.08 or any other Section of this Agreement or as a result of any other inaccuracy or
misrepresentation set forth in such Quarterly Pricing Certificate) shall be deemed cured. 
 5.04. Net Payments. (a) All payments
made by the Borrower hereunder and under any Note will be made without setoff, counterclaim or other defense. Except as provided in Section 5.04(b), all such payments will be made free and clear of, and without deduction or withholding for, any
present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature now or hereafter imposed by any jurisdiction or by any political subdivision or taxing authority thereof or therein with respect to such payments
(but excluding, 
  

 -69- 

 
except as provided in the second succeeding sentence, any tax, levy, impost, duty, fee, assessment or other charge imposed on or measured by the net income
or net profits of a Lender pursuant to the laws of the jurisdiction in which it is organized or the jurisdiction in which the principal office or applicable lending office of such Lender is located or any subdivision thereof or therein, including,
without limitation, any franchise tax, levy, impost, duty, fee, assessment or other charge imposed in lieu of net income tax) and all interest, penalties or similar liabilities with respect to such non-excluded taxes, levies, imposts, duties, fees,
assessments or other charges (all such non-excluded taxes, levies, imposts, duties, fees, assessments or other charges being referred to collectively as “Taxes”). If any Taxes are so levied or imposed, the Borrower agrees to pay the
full amount of such Taxes, and such additional amounts as may be necessary so that every payment of all amounts due under this Agreement or under any Note, after withholding or deduction for or on account of any Taxes, will not be less than the
amount provided for herein or in such Note. If any amounts are payable in respect of Taxes pursuant to the preceding sentence, the Borrower agrees to reimburse each Lender, upon the written request of such Lender, for taxes imposed on or measured by
the net income or net profits of such Lender pursuant to the laws of the jurisdiction in which such Lender is organized or in which the principal office or applicable lending office of such Lender is located or under the laws of any political
subdivision or taxing authority thereof or therein and for any withholding of taxes as such Lender shall determine are payable by, or withheld from, such Lender, in respect of such amounts so paid to or on behalf of such Lender pursuant to the
preceding sentence and in respect of any amounts paid to or on behalf of such Lender pursuant to this sentence, which request shall be accompanied by a statement from such Lender setting forth, in reasonable detail, the computations used in
determining such amounts and including, where available, a copy of the receipt or other reasonably satisfactory evidence of the demand of such amounts or their payment. The Borrower will furnish to the Administrative Agent within 45 days after the
date of the payment of any Taxes due pursuant to applicable law certified copies of tax receipts evidencing such payment by the Borrower. The Borrower agrees to indemnify and hold harmless each Lender, and reimburse such Lender upon its written
request, for the amount of any Taxes so levied or imposed and paid by such Lender. 
 (b) Each Lender agrees to deliver to the Borrower and
the Administrative Agent on or prior to the Effective Date or, in the case of a Lender that is an assignee or transferee of an interest under this Agreement pursuant to Section 2.13 or 13.04(b) (unless the respective Lender was already a Lender
hereunder immediately prior to such assignment or transfer), on the date of such assignment or transfer to such Lender, (I) in the case of a Lender that is not a United States person (as such term is defined in Section 7701(a)(30) of the
Code) for U.S. Federal income tax purposes, (i) two accurate and complete original signed copies of Internal Revenue Service Form W-8ECI or Form W-8BEN (with respect to a complete exemption under an income tax treaty) (or successor forms)
certifying to such Lender’s entitlement as of such date to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement and under any Note, or (ii) if the Lender is not a “bank”
within the meaning of Section 881(c)(3)(A) of the Code and cannot deliver either Internal Revenue Service Form W-8ECI or Form W-8BEN (with respect to a complete exemption under an income tax treaty) (or any successor forms) pursuant to clause
(i) above, (x) a certificate substantially in the form of Exhibit D (any such certificate, a “Section 5.04(b)(ii) Certificate”) and (y) two accurate and complete original signed copies of Internal Revenue Service Form
W-8BEN (with respect to the portfolio interest exemption) (or successor form) certifying to such Lender’s entitlement as of 

  

 -70- 

 
such date to a complete exemption from United States withholding tax with respect to payments of interest to be made under this Agreement and under any Note,
and (II) in the case of a Lender that is a United States person (as such term is defined in Section 7701(a)(30) of the Code) for U.S. Federal income tax purposes (other than a Lender that may be treated as an exempt recipient based on the
indicators described in U.S. Treasury Regulation Section 1.6049-4(c)(1)(ii) except to the extent required by U.S. Treasury Regulation Section 1.1441-1(d)(4) (and any successor provision)), two accurate and complete original signed copies
of Internal Revenue Service Form W-9 (or successor forms) certifying to such Lender’s entitlement as of such date to a complete exemption from United States backup withholding tax with respect to payments to be made under this Agreement
and under any Note. In addition, each Lender agrees that from time to time after the Effective Date, when a lapse in time or change in circumstances renders the previous certification obsolete or inaccurate in any material respect, such Lender will
deliver to the Borrower and the Administrative Agent two new accurate and complete original signed copies of Internal Revenue Service Form W-8ECI, Form W-8BEN (with respect to the benefits of any income tax treaty), Form W-8BEN (with respect to the
portfolio interest exemption) and a Section 5.04(b)(ii) Certificate, or Form W-9, as the case may be, and such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued exemption from or
reduction in United States withholding tax with respect to payments under this Agreement and any Note, or such Lender shall immediately notify the Borrower and the Administrative Agent of its inability to deliver any such Form or Certificate, in
which case such Lender shall not be required to deliver any such Form or Certificate pursuant to this Section 5.04(b). Notwithstanding anything to the contrary contained in Section 5.04(a), but subject to Section 13.04(b) and the
immediately succeeding sentence, (x) the Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold income or similar taxes imposed by the United States (or any political subdivision or taxing authority
thereof or therein) from interest, Fees or other amounts payable hereunder for the account of any Lender to the extent that such Lender has not provided to the Borrower Internal Revenue Service Forms or a Section 5.04(b)(ii) Certificate, as the
case may be, that establish a complete exemption from such deduction or withholding and (y) the Borrower shall not be obligated pursuant to Section 5.04(a) to gross-up payments to be made to a Lender in respect of, or otherwise indemnify,
income or similar taxes imposed by the United States if (I) such Lender has not provided to the Borrower the Internal Revenue Service Forms required to be provided to the Borrower pursuant to this Section 5.04(b) or (II) in the case of a
payment, other than interest, to a Lender described in clause (ii) above, to the extent that such forms do not establish a complete exemption from withholding of such taxes. Notwithstanding anything to the contrary contained in the preceding
sentence or elsewhere in this Section 5.04 and except as set forth in Section 13.04(b), the Borrower agrees to pay any additional amounts and to indemnify each Lender in the manner set forth in Section 5.04(a) (without regard to the
identity of the jurisdiction requiring the deduction or withholding) in respect of any amounts (other than United States backup withholding tax) deducted or withheld by it as described in the immediately preceding sentence as a result of any changes
that are effective after the later of the Effective Date or the date on which such Lender became a party to this Agreement, in any applicable law, treaty, governmental rule, regulation, guideline or order, or in the interpretation thereof, relating
to the deducting or withholding of such Taxes. 
 (c) If any Lender, in its sole discretion, determines that it has received or been granted
a refund or credit in respect of any Taxes paid as to which indemnification has been paid 

  

 -71- 

 
by the Borrower pursuant to this Section 5.04, it shall promptly remit to the Borrower such refund (including any interest received in respect thereof)
or an amount that the Lender shall, in its sole discretion, determine is equal to the net benefit, after tax, that was obtained by the Lender in such year as a consequence of such credit, net of all out-of-pocket costs and expenses of the Lender;
provided, however, that the Borrower agrees to promptly return any such amount to such Lender in the event such Lender is required to repay such refund or credit to the relevant taxing authority (plus interest at the rate applicable to
underpayments of tax). Nothing contained herein shall impose an obligation on any Lender to apply for any such refund or credit or disclose its tax returns or any other information regarding its taxes that it deems confidential. No Lender shall be
required to pay any amounts pursuant to this Section 5.04(c) at any time that a Default or an Event of Default exists.

Consolidated EBITDA shall include the Synergy Cost Savings add-back referred to in clause (A)(vi) in the definition of “Consolidated EBITDA”. 
 6.17. Fees. On the Initial Borrowing Date, the Borrower shall have paid to each Agent (and its relevant affiliates) and each Lender all costs, fees and expenses (including, 

  

 -78- 

 
without limitation, legal fees and expenses) and other compensation contemplated hereby payable to such Agent (or its relevant affiliate) or such Lender to
the extent then due. 
 In determining the satisfaction of the conditions specified in this Section 6, (x) to the extent any item
is required to be satisfactory to any Lender, such item shall be deemed satisfactory to each Lender which has not notified the Administrative Agent in writing prior to the occurrence of the Initial Borrowing Date that the respective item or matter
does not meet its satisfaction and (y) in determining whether any Lender is aware of any fact, condition or event that has occurred and which would reasonably be expected to have a Merger Agreement Material Adverse Effect, each Lender which has
not notified the Administrative Agent in writing prior to the occurrence of the Initial Borrowing Date of such fact, condition or event shall be deemed not to be aware of any such fact, condition or event on the Initial Borrowing Date. Upon the
Administrative Agent’s good faith determination that the conditions specified in this Section 6 have been met (after giving effect to the preceding sentence), then the Initial Borrowing Date shall have been deemed to have occurred,
regardless of any subsequent determination that one or more of the conditions thereto had not been met (although the occurrence of the Initial Borrowing Date shall not release the Borrower from any liability for failure to satisfy one or more of the
applicable conditions contained in this Section 6).

provided in Section 2.01(e) and (y) as hereinafter indicated), to the satisfaction of the following conditions: 
 7.01. No
Default; Representations and Warranties. At the time of each such Credit Event and also after giving effect thereto (i) there shall exist no Default or Event of Default and (ii) all representations and warranties contained herein and

representation or warranty which by its terms is made as of a specified date shall be required to be true and correct in all material respects only as of such specified date). 
 7.02. Notice of Borrowing; Letter of Credit Request. (a) Prior to the making of each Loan (other than a Swingline Loan or a Revolving Loan
made pursuant to a Mandatory Borrowing), the Administrative Agent shall have received a Notice of Borrowing meeting the requirements of Section 2.03(a). Prior to the making of each Swingline Loan, the Swingline Lender shall have received the

Tranche, the Borrower shall have satisfied all of the applicable conditions set forth in Section 2.14 and in the relevant Incremental Term Loan Commitment Agreement. 
 The acceptance of the benefits of each Credit Event shall constitute a representation and warranty by the Borrower to the Administrative Agent and each of the Lenders that all the conditions specified in
Section 6 (with respect to Credit Events on the Initial Borrowing Date) and in this Section 7 (with respect to Credit Events on or after the Initial Borrowing Date) and applicable to such Credit Event are satisfied as of that time. All of
the Notes, certificates, legal opinions and other documents and papers referred to in Section 6 and in this Section 7, unless otherwise specified, shall be delivered to the Administrative Agent at the Notice Office for the account of each
of the Lenders and, except for the Notes, in sufficient counterparts or copies for each of the Lenders and shall be in form and substance reasonably satisfactory to the Administrative Agent and the Required Lenders. 
 SECTION 8. Representations, Warranties and Agreements. 
 In order to induce the Lenders to enter into this Agreement and to make the Loans, and issue (or participate in) the Letters of Credit as provided herein, the Borrower makes the following representations, warranties
and agreements, in each case after giving effect to the Transaction, all of which shall survive the execution and delivery of this Agreement and the Notes and the making of the Loans and the issuance of the Letters of Credit, with the occurrence of
each Credit Event on or after the Initial Borrowing Date being deemed to constitute a representation and warranty that the matters specified in this Section 8 are true and correct in all material respects on and as of the Initial Borrowing Date
and on the date of each such other Credit Event (it being understood and agreed that any representation or warranty which by its terms is made as of a specified date shall be required to be true and correct in all material respects only as of such
specified date). 
 8.01. Company Status. Each of the Borrower and each of its Subsidiaries (i) is a duly organized and validly
existing Company in good standing under the laws of the jurisdiction of its organization, (ii) has the Company power and authority to own its property and assets and to transact the business in which it is engaged and presently proposes to
engage and (iii) is duly qualified and is authorized to do business and is in good standing in each jurisdiction where the ownership, leasing or operation of its property or the conduct of its business requires such qualifications except for
failures to be so qualified or authorized which, either individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. 
 8.02. Power and Authority. Each Credit Party has the Company power and authority to execute, deliver and perform the terms and provisions of each of the Documents to which it is party and has taken all
necessary Company action to authorize the execution, delivery and performance by it of each of such Documents. Each Credit Party has duly executed and delivered each of the Documents to which it is party, and each of such Documents constitutes its
legal, valid and binding obligation enforceable in accordance with its terms, except to the extent that the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws generally
affecting creditors’ rights and by equitable principles (regardless of whether enforcement is sought in equity or at law). 
  

 -80- 

 8.03. No Violation. Neither the execution, delivery or performance by any Credit Party of the
Documents to which it is a party, nor compliance by it with the terms and provisions thereof, (i) will contravene or violate any material provision of any applicable material law, statute, rule or regulation or any material order, writ,
injunction or decree of any court or Governmental Authority, (ii) will conflict with or result in any breach of any of the terms, covenants, conditions or provisions of, or constitute a default under, or result in the creation or imposition of
(or the obligation to create or impose) any Lien (except pursuant to the Security Documents) upon any material portion of the property or assets of any Credit Party or any of its Subsidiaries pursuant to the terms of any material indenture,
mortgage, deed of trust, credit agreement or loan agreement, or any other material agreement, contract or instrument, in each case to which any Credit Party or any of its Subsidiaries is a party or by which it or any of its property or assets is
bound or to which it may be subject (including, without limitation, on and after the execution and delivery thereof, any Permitted Subordinated Debt Document), or (iii) will contravene or violate any provision of the certificate or articles of
incorporation, certificate of formation, limited liability company agreement or by-laws (or equivalent organizational documents), as applicable, of any Credit Party or any of its Subsidiaries. 
 8.04. Approvals. (a) No material order, consent, approval, license, authorization or validation of, or filing, recording or registration with

perfect the security interests created under the Security Documents, which filings will be made within ten days following the Initial Borrowing Date), or exemption by, any Governmental Authority is required to be obtained or made by, or on behalf
of, any Credit Party to authorize, or is required to be obtained or made by, or on behalf of, any Credit Party in connection with, (i) the execution, delivery and performance of any Document or (ii) the legality, validity, binding effect
or enforceability of any such Document. 
 (b) Each of the Borrower and each of its Subsidiaries holds all material Governmental Approvals
and all material approvals of any Governmental Authority having jurisdiction over the Borrower or any such Subsidiary, as applicable, which Governmental Approvals and approvals are necessary or required for the construction and operation of the
Systems. Such Governmental Approvals and other approvals for each System as of the Initial Borrowing Date are correctly listed on Schedule V and constitute the only Governmental Approvals and other material approvals of any Governmental Authority
required in connection with the Systems as are presently operating. All material Governmental Approvals of the Borrower and each of its Subsidiaries are in full force and effect, are duly issued in the name of, or validly assigned to, the Borrower
or such Subsidiary, and the Borrower or such Subsidiary has the power and authority to operate thereunder. 
 8.05. Financial Statements;
Financial Condition; Undisclosed Liabilities; Projections. (a)(i) (I) The audited consolidated balance sheet of each of PAETEC Parent and US LEC at December 31, 2005 and December 31, 2004 and the related consolidated statements of
income and cash flows and changes in stockholders’ equity of each of PAETEC Parent and US LEC for their respective fiscal years ended on such dates (as well as for the fiscal year ended December 31, 2003), in each case furnished to the
Lenders prior to the Effective Date, present fairly in all material respects the consolidated financial position of each of PAETEC Parent and 

  

 -81- 

 
US LEC, respectively, at the date of such financial statements and the results of their respective operations for the respective periods covered thereby and
(II) the unaudited consolidated balance sheet of each of PAETEC Parent and US LEC at June 30, 2006 and at September 30, 2006 and the related consolidated statements of income and cash flows of each of PAETEC Parent and US LEC for the
six-month and ninth-month periods ended on such dates, in each case furnished to the Lenders prior to the Effective Date, present fairly in all material respects the consolidated financial condition of each of PAETEC Parent and US LEC, respectively,
at the date of such financial statements and the results of their respective operations for the periods covered thereby, subject to normal year-end audit adjustments and the absence of footnotes. All such financial statements have been prepared in
accordance with GAAP consistently applied except to the extent provided in the notes to such financial statements and subject, in the case of the unaudited financial statements, to normal year-end audit adjustments (all of which are of a recurring
nature and none of which, individually or in the aggregate, would be material) and the absence of footnotes. 
 (ii) The pro
forma consolidated financial statements of the Borrower and its Subsidiaries as of September 30, 2006 (after giving effect to the Transaction and the financing therefor), a copy of which has been furnished to the Lenders prior to the
Effective Date, present a good faith estimate based on assumptions believed by the Borrower to be reasonable as of the date of delivery thereof and as of the Initial Borrowing Date, of both the pro forma consolidated financial position
of the Borrower and its Subsidiaries as of such date and the pro forma consolidated results of operations of the Borrower and its Subsidiaries for the period covered thereby. 
 (b) On and as of the date of each Credit Event, and after giving effect to all Indebtedness (including the Loans) being incurred or assumed and Liens
created by the Credit Parties in connection therewith on such date, (i) the sum of the assets, at a fair valuation, of each of the Borrower (on a stand-alone basis) and of each Credit Party and its Subsidiaries (taken as a whole) will exceed
its or their respective debts, (ii) each of the Borrower (on a stand-alone basis) and each Credit Party and its Subsidiaries (taken as a whole) has or have not incurred and does or do not intend to incur, and does or do not believe that it or
they will incur, debts beyond its or their respective ability to pay such debts as such debts mature, and (iii) each of the Borrower (on a stand-alone basis) and each Credit Party and its Subsidiaries (taken as a whole) will have sufficient
capital with which to conduct its or their respective businesses. For purposes of this Section 8.05(b), “debt” means any liability on a claim, and “claim” means (a) right to payment, whether or not such a
right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured, or unsecured or (b) right to an equitable remedy for breach of performance if such breach gives rise
to a payment, whether or not such right to an equitable remedy is reduced to judgment, fixed, contingent, matured, unmatured, disputed, undisputed, secured or unsecured. The amount of contingent liabilities at any time shall be computed as the
amount that, in the light of all the facts and circumstances existing at such time, represents the amount that can reasonably be expected to become an actual or matured liability. 
 (c) Except as fully disclosed in the financial statements referred to in Section 8.05(a), and except for the Indebtedness incurred under the Credit
Documents, there were as of the Initial Borrowing Date no liabilities or obligations with respect to the Borrower or 

  

 -82- 

 
any of its Subsidiaries of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether or not due) which, either individually or in
the aggregate, shall have caused a Material Adverse Effect. As of the Initial Borrowing Date, the Borrower knows of no basis for the assertion against it or any of its Subsidiaries of any liability or obligation of any nature whatsoever that is not
fully disclosed in the financial statements referred to in Section 8.05(a) or referred to in the immediately preceding sentence which, either individually or in the aggregate, shall have caused a Material Adverse Effect. 
 (d) The Projections have been prepared in good faith and are based on assumptions believed to be reasonable at the time of preparation thereof and as of
the Initial Borrowing Date, and there are no statements or conclusions in the Projections which are based upon or include information known to the Borrower or any of its Subsidiaries at the time of preparation thereof or as of the Initial Borrowing
Date to be misleading in any material respect or which fail to take into account material information known to the Borrower or any of its Subsidiaries regarding the matters reported therein, it being understood that the actual results during the
period or periods covered by the Projections may differ from the projected results and such differences may be material. 
 (e) After giving
effect to the Transaction (but for this purpose assuming that the Transaction and the related financing had occurred prior to December 31, 2005), since December 31, 2005, nothing has occurred that has had, or could reasonably be expected
to have, a Material Adverse Effect. 
 8.06. Litigation. There are no actions, suits or proceedings pending or, to the knowledge of
the Borrower, threatened in writing (i) with respect to any Document or (ii) that have had, or could reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect. 
 8.07. True and Complete Disclosure. The factual information contained in the Confidential Information Memorandum was true and accurate in all
material respects as of the date thereof and not incomplete by omitting to state any fact necessary to make such information (taken as a whole) not misleading in any material respect at such date in light of the circumstances under which such
information was provided, it being understood and agreed that for purposes of this Section 8.07, such factual information shall not include the Projections or any pro forma financial information contained in the Confidential
Information Memorandum. 
 8.08. Use of Proceeds; Margin Regulations. (a) All proceeds of the Initial Term Loans will be used by
the Borrower to finance, in part, the Refinancing and the Preferred Stock Repurchase and to pay the fees and expenses incurred in connection with the Transaction. 
 (b) The proceeds of all Incremental Term Loans shall be utilized for the working capital, capital expenditures and other general corporate purposes of the Borrower and its Subsidiaries. 
 (c) All proceeds of the Revolving Loans and the Swingline Loans will be used for the working capital, capital expenditures and other general corporate
purposes of the 

  

 -83- 

 
Borrower and its Subsidiaries, provided that no proceeds from Revolving Loans or Swingline Loans may be used for the purposes described in
Section 8.08(a). 
 (d) Except for proceeds of the Initial Term Loans that are used to effect the Preferred Stock Repurchase, no part of
any Credit Event (or the proceeds thereof) will be used to purchase or carry any Margin Stock or to extend credit for the purpose of purchasing or carrying any Margin Stock. Neither the making of any Loan nor the use of the proceeds thereof nor the
occurrence of any other Credit Event will violate or be inconsistent with the provisions of Regulation T, U or X of the Board of Governors of the Federal Reserve System. The fair market value of all Margin Stock owned by the Borrower and its
Subsidiaries (excluding Capital Stock of the Borrower held in treasury) does not exceed $4,000,000. At the time of each Credit Event, not more than 25% of the value of the assets of the Borrower and its Subsidiaries taken as a whole (including all
Capital Stock of the Borrower held in treasury) will constitute Margin Stock. 
 8.09. Tax Returns and Payments. Each of the Borrower
and each of its Subsidiaries has timely filed or caused to be timely filed with the appropriate taxing authority all Federal and other material tax returns, statements, forms and reports for taxes (the “Returns”) required to be
filed by, or with respect to the income, properties or operations of, the Borrower and/or any of its Subsidiaries. The Returns accurately reflect in all material respects all liability for taxes of the Borrower and its Subsidiaries, as applicable,
for the periods covered thereby. Each of the Borrower and each of its Subsidiaries has paid all taxes and assessments payable by it which have become due, other than those that are immaterial and those that are being contested in good faith and
adequately disclosed and fully provided for on the financial statements of the Borrower and its Subsidiaries in accordance with GAAP. There is no material action, suit, proceeding, investigation, audit or claim now pending or, to the knowledge of
the Borrower, threatened by any authority regarding any taxes relating to the Borrower or any of its Subsidiaries. As of the Initial Borrowing Date, neither the Borrower nor any of its Subsidiaries has entered into an agreement or waiver or been
requested to enter into an agreement or waiver extending any statute of limitations relating to the payment or collection of taxes of the Borrower or any of its Subsidiaries, or is aware of any circumstances that would cause the taxable years or
other taxable periods of the Borrower or any of its Subsidiaries not to be subject to the normally applicable statute of limitations. 
 8.10. Compliance with ERISA. Schedule VI sets forth each Plan as of the Initial Borrowing Date; each Plan (and each related trust, insurance contract or fund) is in substantial compliance with its terms and with all applicable laws,
including, without limitation, ERISA and the Code; each Plan (and each related trust, if any) which is intended to be qualified under Section 401(a) of the Code has received a determination letter (or there is pending a submission seeking a
determination letter) from the Internal Revenue Service to the effect that it meets the requirements of Sections 401(a) and 501(a) of the Code or is maintained pursuant to a prototype plan document which is the subject of a favorable opinion letter
from the Internal Revenue Service to the sponsor of the prototype plan document; no Reportable Event has occurred; no Plan which is a multiemployer plan (as defined in Section 4001(a)(3) of ERISA) is insolvent or in reorganization; no Plan has

 -84- 

 
accumulated funding deficiency, within the meaning of such sections of the Code or ERISA, or has applied for or received a waiver of an accumulated funding
deficiency or an extension of any amortization period, within the meaning of Section 412 of the Code or Section 303 or 304 of ERISA; all contributions required to be made with respect to a Plan have been timely made; neither the Borrower
nor any Subsidiary of the Borrower nor any ERISA Affiliate has incurred any material liability (including any indirect, contingent or secondary liability) to or on account of a Plan pursuant to Section 409, 502(i), 502(l), 515, 4062, 4063,
4064, 4069, 4201, 4204 or 4212 of ERISA or Section 401(a)(29), 4971 or 4975 of the Code or expects to incur any such material liability under any of the foregoing sections with respect to any Plan; no condition exists which presents a material
risk to the Borrower or any Subsidiary of the Borrower or any ERISA Affiliate of incurring a material liability to or on account of a Plan pursuant to the foregoing provisions of ERISA and the Code; no proceedings have been instituted to terminate
or appoint a trustee to administer any Plan which is subject to Title IV of ERISA; no action, suit, proceeding, hearing, government audit or investigation with respect to the administration, operation or the investment of assets of any Plan (other
than routine claims for benefits and other immaterial matters) is pending, expected or threatened; using actuarial assumptions and computation methods consistent with Part 1 of subtitle E of Title IV of ERISA, the aggregate liabilities of the
Borrower and its Subsidiaries and its ERISA Affiliates to all Plans which are multiemployer plans (as defined in Section 4001(a)(3) of ERISA) in the event of a complete withdrawal therefrom, as of the close of the most recent fiscal year of
each such Plan ended prior to the date of the most recent Credit Event, would not exceed $4,000,000; each group health plan (as defined in Section 607(1) of ERISA or Section 4980B(g)(2) of the Code) which covers or has covered employees or
former employees of the Borrower, any Subsidiary of the Borrower, or any ERISA Affiliate has at all times been operated in material compliance with the provisions of Part 6 of subtitle B of Title I of ERISA and Section 4980B of the Code; each
group health plan (as defined in 45 Code of Federal Regulations Section 160.103) which covers or has covered employees or former employees of the Borrower, any Subsidiary of the Borrower, or any ERISA Affiliate has at all times been operated in
material compliance with the provisions of the Health Insurance Portability and Accountability Act of 1996 and the regulations promulgated thereunder; no lien imposed under the Code or ERISA on the assets of the Borrower or any Subsidiary of the
Borrower or any ERISA Affiliate exists or is likely to arise on account of any Plan; and the Borrower and its Subsidiaries may cease contributions to or terminate any employee benefit plan (within the meaning of Section 3(3) of ERISA)
maintained by any of them without incurring any material liability.

Security Agreement are effective to create in favor of the Collateral Agent for the benefit of the Secured Creditors a legal, valid and enforceable security interest in all right, title and interest of the Credit Parties in the Security Agreement
Collateral described therein, and the Collateral Agent, for the benefit of the Secured Creditors, has (or within 10 days following the Initial Borrowing Date will have) a fully perfected security interest in all right, title and interest in all of
the Security Agreement Collateral described therein, subject to no other Liens other than Permitted Liens. The recordation of (x) the Grant of Security Interest in U.S. Patents and (y) the Grant of Security Interest in U.S. Trademarks in
the respective form attached to the Security Agreement, in each case in the United States Patent and Trademark Office, together with filings on Form UCC-1 made pursuant to the Security Agreement, will create, as may be perfected by such filings and
recordation, a perfected security interest in the United States trademarks and patents covered by 
  

 -85- 

 
the Security Agreement, and the recordation of the Grant of Security Interest in U.S. Copyrights in the form attached to the Security Agreement with the
United States Copyright Office, together with filings on Form UCC-1 made pursuant to the Security Agreement, will create, as may be perfected by such filings and recordation, a perfected security interest in the United States copyrights covered by
the Security Agreement. 
 (b) The security interests created under the Pledge Agreement in favor of the Collateral Agent, as Pledgee, for
the benefit of the Secured Creditors, constitute perfected security interests in the Pledge Agreement Collateral described in the Pledge Agreement, subject to no security interests of any other Person other than non-consensual Permitted Liens. No
filings or recordings are required in order to perfect (or maintain the perfection or priority of) the security interests created in the Pledge Agreement Collateral under the Pledge Agreement other than with respect to that portion of the Pledge
Agreement Collateral constituting a “general intangible” under the UCC. 
 (c) After the execution, delivery and recordation
thereof in the appropriate filing office, each Mortgage creates, as security for the obligations purported to be secured thereby, a valid and enforceable perfected security interest in and mortgage lien on the respective Mortgaged Property in favor
of the Collateral Agent (or such other trustee as may be required or desired under local law) for the benefit of the Secured Creditors, superior and prior to the rights of all third Persons (except that the security interest and mortgage lien
created on such Mortgaged Property may be subject to the Permitted Encumbrances related thereto which may be superior and other Permitted Liens related thereto) and subject to no other Liens (other than the Permitted Liens related thereto).

 8.12. Properties. All Real Property owned or leased by the Borrower or any of its Subsidiaries as of the Initial Borrowing Date,
and the nature of the interest therein, is set forth in Schedule IV. Each of the Borrower and each of its Subsidiaries has good and indefeasible title to all material properties (and to all buildings, fixtures and improvements located on any
material Real Property) owned by it, including all material property reflected in the most recent historical balance sheets referred to in Section 8.05(a) (except as sold or otherwise disposed of since the date of such balance sheet in the
ordinary course of business or as permitted by the terms of this Agreement), free and clear of all Liens, other than Permitted Liens. Each of the Borrower and each of its Subsidiaries has a valid and indefeasible leasehold interest in the material
properties leased by it free and clear of all Liens other than Permitted Liens. 
 8.13. Capitalization. On the Initial Borrowing
Date, the authorized Capital Stock of the Borrower consists of (i) 300,000,000 shares of Common Stock, par value $0.01 per share (such authorized shares of Common Stock, together with any subsequently authorized shares of Common Stock of the
Borrower, the “Borrower Common Stock”), and (ii) 20,000,000 shares of preferred stock, par value $0.01 per share, of which no shares are issued and outstanding. All outstanding shares of Capital Stock of the Borrower have been
duly and validly issued, are fully paid and non-assessable and have been issued free of preemptive rights. On the Initial Borrowing Date, the Borrower does not have outstanding any securities convertible into or exchangeable for its Capital Stock or
outstanding any rights to subscribe for or to purchase, or any options for the purchase of, or any agreement providing for the issuance (contingent or otherwise) of, or any calls, commitments or claims of any character relating to, its Capital Stock

  

 -86-

Permitted Acquisition for a reasonable period thereafter. 
 9.09. Performance of Obligations. The Borrower will, and will cause each
of its Subsidiaries to, perform in all material respects all of its material obligations under the terms of 

  

 -96- 

 
each mortgage, indenture, security agreement, loan agreement or credit agreement and each other material agreement, contract or instrument by which it is
bound. 
 9.10. Payment of Taxes. The Borrower will pay and discharge, and will cause each of its Subsidiaries to pay and discharge,
all taxes, assessments and governmental charges or levies imposed upon it or upon its income or profits or upon any properties belonging to it, prior to the date on which penalties attach thereto, and all lawful claims which, if unpaid, might become
a Lien or charge upon any properties of the Borrower or any of its Subsidiaries not otherwise permitted under Section 10.01(i), provided that neither the Borrower nor any of its Subsidiaries shall be required to pay any such tax,
assessment, charge, levy or claim which is immaterial or which is being contested in good faith and by proper proceedings if the Borrower or such Subsidiary has maintained adequate reserves with respect thereto in accordance with GAAP. 

9.11. Use of Proceeds. The Borrower will use the proceeds of the Loans only as provided in Section 8.08. 
 9.12. Additional Security; Further Assurances; etc. (a) The Borrower will, and will cause each other Credit Party to, grant to the Collateral
Agent for the benefit of the Secured Creditors security interests and Mortgages in such assets and fee-owned Real Property of the Borrower and the other Credit Parties as are not covered by the original Security Documents and as may be reasonably
requested from time to time by the Administrative Agent or the Required Lenders (collectively, the “Additional Security Documents”). All such security interests and Mortgages shall be granted pursuant to documentation reasonably
satisfactory in form and substance to the Collateral Agent and, following delivery of assets to the Collateral Agent and the filing and/or recordation of the necessary UCC-1 financing statements, documents with the United States Patent and Trademark
Office and the United States Copyright Office (with respect to intellectual property rights, to the extent that such perfection and priority may be achieved by filings made in the United States Patent and Trademark Office and the United States
Copyright Office or otherwise deemed advisable by the Administrative Agent), and/or mortgages in the appropriate jurisdiction, shall constitute valid and enforceable perfected security interests, hypothecations and Mortgages superior to and prior to
the rights of all third Persons (except that the security interest and mortgage lien created in such Real Property may be subject to Permitted Encumbrances which may be superior) and enforceable against third parties and subject to no other Liens
except for Permitted Liens or, in the case of Real Property, the Permitted Encumbrances related thereto. The Additional Security Documents or instruments related thereto shall be duly recorded or filed in such manner and in such places as are
required by law to establish, perfect, preserve and protect the Liens in favor of the Collateral Agent required to be granted pursuant to the Additional Security Documents and all taxes, fees and other charges payable in connection therewith shall
be paid in full. 
 (b) The Borrower will, and will cause each of the other Credit Parties to, at the expense of the Borrower, make, execute,
endorse, acknowledge, file and/or deliver to the Collateral Agent from time to time such schedules, confirmatory assignments, conveyances, financing statements, transfer endorsements, powers of attorney, certificates, real property surveys on
Mortgaged Properties, reports, landlord waivers, control agreements and other assurances or instruments and take such further steps relating to the Collateral covered by any of 

  

 -97- 

 
the Security Documents as the Collateral Agent may reasonably require (including, without limitation, amending and/or causing amendments to the Credit
Documents relating to Collateral matters, as the Administrative Agent shall reasonably request). Furthermore, the Borrower will, and will cause the other Credit Parties to, deliver to the Collateral Agent such opinions of counsel, title insurance on
Mortgaged Properties and other related documents as may be reasonably requested by the Administrative Agent to assure itself that this Section 9.12 has been complied with. 
 (c) If the Administrative Agent, the Collateral Agent or the Required Lenders reasonably determine that they are required by law or regulation to have
appraisals prepared in respect of any Real Property of the Borrower and the other Credit Parties constituting Collateral, the Borrower will, at its own expense, provide to the Collateral Agent appraisals which satisfy the applicable requirements of
the Real Estate Appraisal Reform Amendments of the Financial Institution Reform, Recovery and Enforcement Act of 1989, as amended, and which shall otherwise be in form and substance reasonably satisfactory to the Collateral Agent. 
 (d) At the request of the Collateral Agent or the Required Lenders, the Borrower will, or will cause the relevant Subsidiary of the Borrower to, deliver
to the Collateral Agent (i) collateral assignments of all material third party agreements relating to each System, consented to by the applicable third parties thereto, (ii) evidence that all necessary Governmental Approvals for each
System have been obtained and (iii) with respect to each real estate and material equipment lease and each mortgage relating to each System (x) the right from the applicable lessors and mortgagees to cure all payment defaults under such
leases and mortgages by making payments directly to the applicable lessors and mortgagees and (y) in the case of a leased facility, landlord waivers and consents or such other documentation as the Collateral Agent may require. 
 (e) The Borrower agrees that each action required by clauses (a) through (d) of this Section 9.12 shall be completed as soon as possible,
but in no event later than 60 days after such action is requested to be taken by the Administrative Agent, the Collateral Agent or, as applicable, the Required Lenders (as such date may be extended by the Administrative Agent in its sole
discretion), provided that, except with respect to the actions set forth in clause (ii) of Section 9.12(d), in no event will the Borrower or any of its Subsidiaries be required to take any action, other than using its commercially
reasonable efforts, to obtain consents from third parties with respect to its compliance with this Section 9.12 (it being understood and agreed that such commercially reasonable efforts shall not include the payment of any amounts to
third-parties other than the payment of reasonable fees and disbursements of counsel to such third-parties in connection therewith). 
 9.13.
Ownership of Subsidiaries; etc. Except as otherwise permitted by this Agreement, the Borrower will, and will cause each of its Subsidiaries to, own 100% of the Equity Interests of each of their Subsidiaries (other than directors’
qualifying shares or investments by foreign nationals to the extent required by applicable law). 
 9.14. Interest Rate Protection. No
later than 90 days following the Initial Borrowing Date, the Borrower will enter into (and thereafter maintain) Interest Rate Protection Agreements mutually acceptable to the Borrower and the Administrative Agent, having a term of 

  

 -98- 

 
at least two years, establishing a fixed or maximum interest rate for an aggregate notional principal amount equal to at least 50% of the aggregate principal
amount of the Initial Term Loans incurred on the Initial Borrowing Date. 
 9.15. Permitted Acquisitions. (a) Subject to the
provisions of this Section 9.15 and the requirements contained in the definition of Permitted Acquisition, the Borrower, each Wholly-Owned Domestic Subsidiary of the Borrower which is a Subsidiary Guarantor and, in the case of Foreign Permitted
Acquisition, each Wholly-Owned Foreign Subsidiary of the Borrower, may from time to time effect Permitted Acquisitions, so long as (in each case except to the extent the Required Lenders otherwise specifically agree in writing in the case of a
specific Permitted Acquisition): (i) no Default or Event of Default shall have occurred and be continuing at the time of the consummation of the proposed Permitted Acquisition or immediately after giving effect thereto; (ii) the Borrower
shall have given to the Administrative Agent at least 10 Business Days’ prior written notice of any Permitted Acquisition (or such shorter period of time as may be reasonably acceptable to the Administrative Agent), which notice shall
describe in reasonable detail the principal terms and conditions of such Permitted Acquisition; (iii) calculations are made by the Borrower with respect to the Financial Covenants for the respective Calculation Period on a Pro
Forma Basis as if the respective Permitted Acquisition (as well as all other Permitted Acquisitions theretofore consummated after the first day of such Calculation Period) had occurred on the first day of such Calculation Period, and such
calculations shall show that the Financial Covenants would have been complied with as of the last day of such Calculation Period if the Permitted Acquisition had occurred on the first day of such Calculation Period; (iv) all representations and
warranties contained herein and in the other Credit Documents shall be true and correct in all material respects with the same effect as though such representations and warranties had been made on and as of the date of such Permitted Acquisition
(both before and after giving effect thereto), unless stated to relate to a specific earlier date, in which case such representations and warranties shall be true and correct in all material respects as of such earlier date; (v) in the case of
a Foreign Permitted Acquisition, the Aggregate Consideration payable for the proposed Foreign Permitted Acquisition, when added to the Aggregate Consideration paid or payable for all other Foreign Permitted Acquisitions theretofore consummated since
the Initial Borrowing Date, does not exceed the sum of (I) $25,000,000 plus (II) the Foreign Permitted Acquisition Additional Equity Amount; (vi) immediately before and after giving effect to such Permitted Acquisition (but, for
this purpose calculated as if the payment of all post-closing purchase price adjustments required (in the reasonable determination of the Borrower) in connection with such Permitted Acquisition (and all other Permitted Acquisitions for which such
purchase price adjustments may be required to be made) and all Capital Expenditures (and the financing thereof) reasonably anticipated by the Borrower to be made in the business acquired pursuant to such Permitted Acquisition within the 360-day
period (such period for any Permitted Acquisition, a “Post-Closing Period”) following such Permitted Acquisition (and in the businesses acquired pursuant to all other Permitted Acquisitions with Post-Closing Periods ended during the
Post-Closing Period of such Permitted Acquisition) were then being paid with the proceeds of Revolving Loans), the sum of (x) the Unrestricted cash and Cash Equivalents of the Borrower and the Subsidiary Guarantors plus (y) the
Total Unutilized Revolving Loan Commitment at such time shall equal or exceed $20,000,000; and (vii) the Borrower shall have delivered to the Administrative Agent a certificate executed by its Chief Financial Officer, certifying to the best of
such officer’s knowledge, compliance with the requirements of preceding clauses (i) through (vi), inclusive, 

  

 -99- 

 
and containing the calculations (in reasonable detail) required by preceding clauses (iii), (v) (in the case of a Foreign Permitted Acquisition) and
(vi). 
 (b) At the time of each Permitted Acquisition involving the creation or acquisition of a Subsidiary, or the acquisition of Capital
Stock of any Person, the Capital Stock thereof created or acquired in connection with such Permitted Acquisition shall be pledged for the benefit of the Secured Creditors pursuant to (and to the extent required by) the Pledge Agreement. 

(c) The Borrower will cause each Subsidiary which is formed to effect, or is acquired pursuant to, a Permitted Acquisition to comply with, and to
execute and deliver all of the documentation as and to the extent required by, Sections 9.12 and 10.13, to the reasonable satisfaction of the Administrative Agent and the Collateral Agent. 
 (d) The consummation of each Permitted Acquisition shall be deemed to be a representation and warranty by the Borrower that the certifications pursuant
to this Section 9.15 are true and correct and that all conditions thereto have been satisfied and that same is permitted in accordance with the terms of this Agreement, which representation and warranty shall be deemed to be a representation
and warranty for all purposes hereunder, including, without limitation, Sections 8 and 11. 
 9.16. Foreign Subsidiaries Security. If following a change in the relevant sections of the Code or the regulations, rules, rulings, notices or other official pronouncements issued or promulgated thereunder,
counsel for the Borrower reasonably acceptable to the Administrative Agent does not within 30 days after a request from the Administrative Agent or the Required Lenders deliver evidence, in form and substance mutually satisfactory to the
Administrative Agent and the Borrower, with respect to any Foreign Subsidiary of the Borrower which has not already had all of its Equity Interests pledged pursuant to the Pledge Agreement to secure all of the Obligations (as defined in the Pledge
Agreement) that (i) a pledge of 66 2/3% or more of the total combined voting power of all classes of Equity
Interests of such Foreign Subsidiary entitled to vote, (ii) the entering into by such Foreign Subsidiary of a security agreement in substantially the form of the Security Agreement, (iii) the entering into by such Foreign Subsidiary of a
pledge agreement in substantially the form of the Pledge Agreement and (iv) the entering into by such Foreign Subsidiary of a guaranty in substantially the form of the Subsidiaries Guaranty, in any such case could reasonably be expected to
cause the undistributed earnings of such Foreign Subsidiary as determined for U.S. Federal income tax purposes to be treated as a deemed dividend to such Foreign Subsidiary’s United States parent for U.S. Federal income tax purposes, then in
the case of a failure to deliver the evidence described in clause (i) above, that portion of such Foreign Subsidiary’s outstanding Equity Interests so issued by such Foreign Subsidiary, in each case not theretofore pledged pursuant to the
Pledge Agreement to secure all of the Obligations (as defined in the Pledge Agreement), shall be pledged to the Collateral Agent for the benefit of the Secured Creditors pursuant to the Pledge Agreement (or another pledge agreement in substantially
similar form, if needed), and in the case of a failure to deliver the evidence described in clause (ii) or (iii) above, such Foreign Subsidiary shall execute and deliver the Security Agreement (or another security agreement in
substantially similar form, if needed) or the Pledge Agreement (or another pledge agreement in substantially similar form, if needed), as the case may be, granting to the Collateral Agent for the benefit of the Secured 

  

 -100- 

 
Creditors a security interest in all of such Foreign Subsidiary’s assets or Equity Interests and promissory notes, in each case, owned by such Foreign
Subsidiary, as the case may be, and securing the obligations of the Borrower under the Credit Documents and under any Interest Rate Protection Agreement entitled to the benefits of such Security Documents and, in the event the Subsidiaries Guaranty
shall have been executed by such Foreign Subsidiary, the obligations of such Foreign Subsidiary thereunder, and in the case of a failure to deliver the evidence described in clause (iv) above, such Foreign Subsidiary shall execute and deliver
the Subsidiaries Guaranty (or another guaranty in substantially similar form, if needed), guaranteeing the obligations of the Borrower under the Credit Documents and under any Interest Rate Protection Agreement entitled to the benefits of such
Subsidiaries Guaranty, in each case to the extent that the entering into of such Security Agreement, the Pledge Agreement or the Subsidiaries Guaranty (or substantially similar document) is permitted by the laws of the respective foreign
jurisdiction and with all documents delivered pursuant to this Section 9.16 to be in form and substance reasonably satisfactory to the Administrative Agent and/or the Collateral Agent. 
 9.17. Corporate Separateness. The Borrower will take, and will cause each of its Subsidiaries and Unrestricted Subsidiaries to take, all
action as is necessary to keep the operations of the Borrower and its Subsidiaries separate and apart from those of any Unrestricted Subsidiaries, including, without limitation, ensuring that all customary formalities regarding their respective
corporate existence, including holding regular board of directors’ and shareholders’ meetings and maintenance of corporate offices and records, are followed. Neither the Borrower nor any of its Subsidiaries will make any payment to a
creditor of any Unrestricted Subsidiary in respect of any liability of any Unrestricted Subsidiary (other than tax or other payments to Governmental Authorities for which the Borrower generally makes payments on behalf of its consolidated group).
All financial statements provided to creditors shall clearly evidence the corporate separateness of the Borrower and its Subsidiaries from any Unrestricted Subsidiaries, and the Borrower and its Subsidiaries will maintain their own respective
payroll and separate books of account and bank accounts from Unrestricted Subsidiaries. Each Unrestricted Subsidiary will pay its respective liabilities, including all administrative expenses, from its own separate assets, and assets of the Borrower
and its Subsidiaries will at all times be separately identified and segregated from the assets of Unrestricted Subsidiaries. Neither the Borrower nor any of its Subsidiaries or Unrestricted Subsidiaries will take any action, or conduct its affairs
in a manner, which is likely to result in the corporate existence of any Unrestricted Subsidiary being ignored, or in the assets and liabilities of any Unrestricted Subsidiary being substantively consolidated with those of the Borrower or any of its
Subsidiaries in a bankruptcy, reorganization or other insolvency proceeding. 
 SECTION 10. Negative Covenants. 
 The Borrower hereby covenants and agrees that on and after the Effective Date and until the Total Commitment and all Letters of Credit have terminated
and the Loans, Notes and Unpaid Drawings (in each case, together with interest thereon), Fees and all other Obligations (other than any indemnities described in Section 13.13 which are not then due and payable) incurred hereunder and
thereunder, are paid in full: 
 10.01. Liens. The Borrower will not, and will not permit any of its Subsidiaries to, create, incur,
assume or suffer to exist any Lien upon or with respect to any property or assets 

  

 -101- 

 
(real or personal, tangible or intangible) of the Borrower or any of its Subsidiaries, whether now owned or hereafter acquired, or sell any such property or
assets subject to an understanding or agreement, contingent or otherwise, to repurchase such property or assets (including sales of accounts receivable with recourse to the Borrower or any of its Subsidiaries), or assign any right to receive income
or permit the filing of any financing statement under the UCC or any other similar notice of Lien under any similar recording or notice statute, provided that the provisions of this Section 10.01 shall not prevent the creation,
incurrence, assumption or existence of the following (Liens described below are herein referred to as “Permitted Liens”): 
 (i) inchoate Liens for taxes, assessments or governmental charges or levies not yet due or Liens for taxes, assessments or governmental charges or levies being contested in good faith and by appropriate proceedings
for which adequate reserves have been established in accordance with GAAP;

liens and other similar Liens arising in the ordinary course of business, and (x) which do not in the aggregate materially detract from the value of the Borrower’s or such Subsidiary’s property or assets or materially impair the use
thereof in the operation of the business of the Borrower or such Subsidiary or (y) which are being contested in good faith by appropriate proceedings for which adequate reserves have been established in accordance with GAAP, which proceedings
have the effect of preventing the forfeiture or sale of the property or assets subject to any such Lien; 
 (iii) Liens in
existence on the Initial Borrowing Date which are listed, and the property subject thereto described, in Schedule IX, but only to the respective date, if any, set forth in such Schedule IX for the removal, replacement and termination of any such
Liens, plus renewals, replacements and extensions of such Liens, provided that (x) the aggregate principal amount of the Indebtedness, if any, secured by such Liens does not increase from that amount outstanding at the time of any
such renewal, replacement or extension and (y) any such renewal, replacement or extension does not encumber any additional assets or properties of the Borrower or any of its Subsidiaries; 
 (iv) Liens created by or pursuant to this Agreement and the other Credit Documents; 
 (v) (x) licenses, sublicenses, leases or subleases granted by the Borrower or any of its Subsidiaries to other Persons not materially

Subsidiaries;

after the Initial Borrowing Date and used in the ordinary course of business of the Borrower or any of its Subsidiaries and placed at the time of the acquisition thereof by the Borrower or such Subsidiary or within 180 days thereafter to secure
Indebtedness incurred to pay all or a portion of the purchase price thereof or to secure Indebtedness incurred solely for the purpose of financing the acquisition of any such Telecommunications Equipment and other equipment or machinery or
extensions, renewals or replacements of any of the foregoing for the same or a lesser amount, provided that (x) the Indebtedness secured by such Liens is permitted by Section 10.04(iv) and (y) in all events, the Lien
encumbering the equipment or machinery so acquired does not encumber any other asset of the Borrower or such Subsidiary; 
 (viii) easements, rights-of-way, restrictions, encroachments and other similar charges or encumbrances, and minor title deficiencies, in each case not securing Indebtedness and not materially interfering with the conduct of the business of
the Borrower or any of its Subsidiaries; 
 (ix) Liens arising from precautionary UCC financing statement filings regarding
operating leases entered into in the ordinary course of business or from UCC financing statement filings or any other similar notices of Lien under any similar recording or notice statute regarding Liens permitted under any other clauses of this
Section 10.01; 
 (x) Liens arising out of the existence of judgments or awards in respect of which the Borrower or any
of its Subsidiaries shall in good faith be prosecuting an appeal or proceedings for review and in respect of which there shall have been secured a subsisting stay of execution pending such appeal or proceedings, provided that the aggregate
amount of all cash and the Fair Market Value of all other property subject to such Liens does not exceed $15,000,000 at any time outstanding; 
 (xi) statutory and common law landlords’ liens under leases to which the Borrower or any of its Subsidiaries is a party;

not incurred in connection with, or in contemplation or anticipation of, such Permitted Acquisition and do not attach to any other asset of the Borrower or any of its Subsidiaries; 
 (xv) Liens arising out of any conditional sale, title retention, consignment or other similar arrangements for the sale of goods entered
into by the Borrower or any of its Subsidiaries in the ordinary course of business to the extent such Liens do not attach to any assets other than the goods subject to such arrangements; 
 (xvi) Liens incurred in the ordinary course of business in connection with the purchase or shipping of goods or assets (or the related

facilitate the purchase, shipment or storage of such goods or assets; 
 (xvii) bankers’ Liens, rights of setoff and
other similar Liens existing solely with respect to (x) cash and Cash Equivalents on deposit in one or more accounts maintained by the Borrower or any Subsidiary of the Borrower, in each case granted in the ordinary course of business in favor

their respective duties hereunder by or through its respective officers, directors, agents, employees or affiliates. 
 (b) The provisions of
this Section 12 are solely for the benefit of the Administrative Agent, the Syndication Agent, the Documentation Agent and the Lenders, and neither the Borrower nor any of its Subsidiaries shall have any rights as a third party beneficiary of

of each Note, to the extent it deems appropriate, has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of the Borrower and its Subsidiaries in connection with the making and the
continuance of the Loans and the taking or not taking of any action in connection herewith and (ii) its own appraisal of the creditworthiness of the Borrower and its Subsidiaries and, except as expressly provided in this Agreement or any other

possession before the making of the Loans or at any time or times thereafter. No Agent shall be responsible to any Lender or the holder of any Note for any recitals, statements, information, representations or warranties herein or in any document,
certificate or other writing delivered in connection herewith or for the execution, effectiveness, genuineness, validity, enforceability, perfection, collectibility, priority or sufficiency of this Agreement or any other Credit Document or the
financial condition of the Borrower or any of its Subsidiaries or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement or any other Credit Document or the

Agent shall be entitled to refrain from such act or taking such action unless and until such Agent shall have received instructions from the Required Lenders; and such Agent shall not incur liability to any Lender by reason of so refraining. Without
limiting the foregoing, neither any Lender nor the holder of any Note shall have any right of action whatsoever against any Agent as a result of such Agent acting or refraining from acting hereunder or under any other Credit Document in accordance
with the instructions of the Required Lenders. 
 12.05. Reliance. Each Agent shall be entitled to rely, and shall be fully protected
in relying, upon any note, writing, resolution, notice, statement, certificate, telecopier message, order or other document or telephone message signed, sent or made by any Person that such Agent believed to be the proper Person, and, with respect
to all legal matters pertaining to this Agreement and any other Credit Document and its duties hereunder and thereunder, upon advice of counsel selected by such Agent. 
 12.06. Indemnification. (a) To the extent any Agent (or any affiliate thereof) is not reimbursed and indemnified by the Borrower, the Lenders will reimburse and indemnify such Agent (and any
affiliate thereof) in proportion to their respective “percentage” as used in determining the Required Lenders (determined as if there were no Defaulting Lenders), for and against any and all liabilities, obligations, losses, damages,
penalties, claims, actions, judgments, 

  

 -127- 

 
costs, expenses or disbursements of whatsoever kind or nature which may be imposed on, asserted against or incurred by such Agent (or any affiliate thereof)
in performing its respective duties hereunder or under any other Credit Document or in any way relating to or arising out of this Agreement or any other Credit Document, provided that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, claims, actions, judgments, suits, costs, expenses or disbursements resulting from such Agent’s (or such affiliate’s) gross negligence or willful misconduct (as determined by a court of
competent jurisdiction in a final and non-appealable decision). 
 (b) Any Agent shall be fully justified in failing or refusing to take any
action hereunder and under any other Credit Document (except actions expressly required to be taken by it hereunder or under the Credit Documents) unless it shall first be indemnified to its satisfaction by the Lenders pro rata against
any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action. 
 (c) The agreements in
this Section 12.06 shall survive the payment of all Obligations. 
 12.07. The Agents in Their Individual Capacities. With
respect to its obligation to make Loans, or issue or participate in Letters of Credit, under this Agreement, each Agent shall have the rights and powers specified herein for a “Lender” and may exercise the same rights and powers as
though it were not performing the duties specified herein; and the term “Lender”, “Required Lenders”, “Majority Lenders”, “holders of Notes” or any similar terms shall, unless the context clearly indicates
otherwise, include each Agent in its individual capacity. Each Agent and its affiliates may accept deposits from, lend money to, and generally engage in any kind of banking, investment banking, trust or other business with, or provide debt
financing, equity capital or other services (including financial advisory services) to, any Credit Party or any Affiliate of any Credit Party (or any Person engaged in a similar business with any Credit Party or any Affiliate thereof) as if they
were not performing the duties specified herein, and may accept fees and other consideration from any Credit Party or any Affiliate of any Credit Party for services in connection with this Agreement and otherwise without having to account for the
same to the Lenders. 
 12.08. Holders. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all
purposes hereof unless and until a written notice of the assignment, transfer or endorsement thereof, as the case may be, shall have been filed with the Administrative Agent. Any request, authority or consent of any Person who, at the time of making
such request or giving such authority or consent, is the holder of any Note shall be conclusive and binding on any subsequent holder, transferee, assignee or endorsee, as the case may be, of such Note or of any Note or Notes issued in exchange
therefor. 
 12.09. Resignation of the Agents. (a) The Administrative Agent may resign from the performance of all its
functions and duties hereunder and/or under the other Credit Documents at any time by giving 15 Business Days’ prior written notice to the Lenders and, unless a Default or an Event of Default under Section 11.05 then exists, the Borrower.
Any such resignation by the Administrative Agent hereunder shall also constitute its resignation as an Issuing Lender and the Swingline Lender, in which case the resigning Administrative Agent 

  

 -128- 

 
(x) shall not be required to issue any further Letters of Credit make any additional Swingline Loans hereunder and (y) shall maintain all of its rights
as Issuing Lender or Swingline Lender, as the case may be, with respect to any Letters of Credit issued by it, or Swingline Loans made by it, prior to the date of such resignation. Such resignation shall take effect upon the appointment of a
successor Administrative Agent pursuant to clauses (b) and (c) below or as otherwise provided below. 
 (b) Upon any such notice of
resignation by the Administrative Agent, the Required Lenders shall appoint a successor Administrative Agent hereunder or thereunder who shall be a commercial bank or trust company acceptable to the Borrower, which acceptance shall not be
unreasonably withheld or delayed (provided that the Borrower’s approval shall not be required if an Event of Default then exists). 
 (c) If a successor Administrative Agent shall not have been so appointed within such 15 Business Day period, the Administrative Agent, with the consent of the Borrower (which consent shall not be unreasonably withheld or delayed,
provided that the Borrower’s consent shall not be required if an Event of Default then exists), shall then appoint a successor Administrative Agent who shall serve as Administrative Agent hereunder or thereunder until such time, if any,
as the Required Lenders appoint a successor Administrative Agent as provided above. 
 (d) If no successor Administrative Agent has been
appointed pursuant to clause (b) or (c) above by the 20th Business Day after the date such notice of resignation was given by the Administrative Agent, the Administrative Agent’s resignation shall become effective and the Required
Lenders shall thereafter perform all the duties of the Administrative Agent hereunder and/or under any other Credit Document until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided above. 
 (e) Each of the Syndication Agent and the Documentation Agent may resign from the performance of all its functions and duties hereunder and/or under the
other Credit Documents at any time by giving five Business Days’ prior written notice to the Lenders. Such resignation shall take effect at the end of such five Business Day period. 
 (f) Upon a resignation of any Agent pursuant to this Section 12.09, such Agent shall remain indemnified to the extent provided in this Agreement and
the other Credit Documents and the provisions of this Section 12 (and the analogous provisions of the other Credit Documents) shall continue in effect for the benefit of such Agent for all of its actions and inactions while serving as such
Agent. 
 12.10. Collateral Matters. (a) Each Lender authorizes and directs the Collateral Agent to enter into the
Security Documents for the benefit of the Lenders and the other Secured Creditors. Each Lender hereby agrees, and each holder of any Note by the acceptance thereof will be deemed to agree, that, except as otherwise set forth herein, any action taken
by the Required Lenders in accordance with the provisions of this Agreement or the Security Documents, and the exercise by the Required Lenders of the powers set forth herein or therein, together with such other powers as are reasonably incidental
thereto, shall be authorized and binding upon all of the Lenders. The Collateral Agent is hereby authorized on behalf of all of 

  

 -129- 

 
the Lenders, without the necessity of any notice to or further consent from any Lender, from time to time prior to an Event of Default, to take any action
with respect to any Collateral or Security Documents which may be necessary to perfect and maintain perfected the security interest in and liens upon the Collateral granted pursuant to the Security Documents. 
 (b) The Lenders hereby authorize the Collateral Agent, at its option and in its discretion, to release any Lien granted to or held by the Collateral
Agent upon any Collateral (i) upon termination of the Commitments and payment and satisfaction of all of the Obligations (other than inchoate indemnification obligations) at any time arising under or in respect of this Agreement or the Credit
Documents or the transactions contemplated hereby or thereby, (ii) constituting property being sold or otherwise disposed of (to Persons other than the Borrower and its Subsidiaries) upon the sale or other disposition thereof in compliance with
Section 10.02, (iii) if approved, authorized or ratified in writing by the Required Lenders (or all of the Lenders hereunder, to the extent required by Section 13.12) or (iv) as otherwise may be expressly provided in the relevant
Security Documents. Upon request by the Administrative Agent at any time, the Lenders will confirm in writing the Collateral Agent’s authority to release particular types or items of Collateral pursuant to this Section 12.10. 

(c) The Collateral Agent shall have no obligation whatsoever to the Lenders or to any other Person to assure that the Collateral exists or is owned by
any Credit Party or is cared for, protected or insured or that the Liens granted to the Collateral Agent herein or pursuant hereto have been properly or sufficiently or lawfully created, perfected, protected or enforced or are entitled to any
particular priority, or to exercise or to continue exercising at all or in any manner or under any duty of care, disclosure or fidelity any of the rights, authorities and powers granted or available to the Collateral Agent in this Section 12.10
or in any of the Security Documents, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, the Collateral Agent may act in any manner it may deem appropriate, in its sole discretion, given
the Collateral Agent’s own interest in the Collateral as one of the Lenders and that the Collateral Agent shall have no duty or liability whatsoever to the Lenders, except for its gross negligence or willful misconduct (as determined by a court
of competent jurisdiction in a final and non-appealable decision). 
 12.11. Delivery of Information. The Administrative Agent shall
not be required to deliver to any Lender originals or copies of any documents, instruments, notices, communications or other information received by the Administrative Agent from any Credit Party, any Subsidiary, the Required Lenders, any Lender or
any other Person under or in connection with this Agreement or any other Credit Document except (i) as specifically provided in this Agreement or any other Credit Document and (ii) as specifically requested from time to time in writing by
any Lender with respect to a specific document, instrument, notice or other written communication received by and in the possession of the Administrative Agent at the time of receipt of such request and then only in accordance with such specific
request. 
 12.12. Notice of Default, etc. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence
of any Default or Event of Default unless the Administrative Agent has actually received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a
“notice of default.” In the event that the Administrative Agent receives such a notice, 

  

 -130- 

 
the Administrative Agent shall give prompt notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or
Event of Default as shall be reasonably directed by the Required Lenders; provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such
action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders (as determined by the Administrative Agent in its sole discretion). 
 SECTION 13. Miscellaneous. 
 13.01.
Payment of Expenses, etc. The Borrower hereby agrees to: (i) whether or not the transactions herein contemplated are consummated, pay all reasonable out-of-pocket costs and expenses of the Administrative Agent (including, without
limitation, the reasonable fees and disbursements of White & Case LLP and the Administrative Agent’s other counsel and consultants) in connection with the preparation, execution, delivery and administration of this Agreement and the
other Credit Documents and the documents and instruments referred to herein and therein and any amendment, waiver or consent relating hereto or thereto, of the Administrative Agent and its Affiliates in connection with its or their syndication
efforts with respect to this Agreement and of the Administrative Agent and, after the occurrence of an Event of Default, each of the Issuing Lenders and Lenders in connection with the enforcement of this Agreement and the other Credit Documents and
the documents and instruments referred to herein and therein or in connection with any refinancing or restructuring of the credit arrangements provided under this Agreement in the nature of a “work-out” or pursuant to any insolvency or
bankruptcy proceedings (including, in each case without limitation, the reasonable fees and disbursements of counsel and consultants for the Administrative Agent and, after the occurrence of an Event of Default, counsel for each of the Issuing
Lenders and Lenders); (ii) pay and hold the Administrative Agent, each of the Issuing Lenders and each of the Lenders (and their respective Affiliates) harmless from and against any and all present and future stamp, documentary, transfer, sales
and use, value added, excise and other similar taxes with respect to the foregoing matters, the performance of any obligation under this Agreement or any other Credit Document or any payment thereunder, and save the Administrative Agent, each of the
Issuing Lenders and each of the Lenders harmless from and against any and all liabilities with respect to or resulting from any delay or omission (other than to the extent attributable to the Administrative Agent, such Issuing Lender or such Lender)
to pay such taxes; and (iii) indemnify the Administrative Agent, the Syndication Agent, the Documentation Agent, the Joint Lead Arrangers, the Joint Lead Bookrunners, each Issuing Lender, each Lender and each of their respective Affiliates, and
each of their and their Affiliates’ respective officers, directors, employees, representatives, agents, affiliates, trustees and investment advisors from and hold each of them harmless against any and all liabilities, obligations (including
removal or remedial actions), losses, damages, penalties, claims, actions, judgments, suits, costs, expenses and disbursements (including reasonable attorneys’ and consultants’ fees and disbursements) incurred by, imposed on or assessed
against any of them as a result of, or arising out of, or in any way related to, or by reason of, (a) any investigation, litigation or other proceeding (whether or not the Administrative Agent, the Syndication Agent, the Documentation Agent,
any Joint Lead Arranger, any Joint Lead Bookrunner, any Issuing Lender or any Lender is a party thereto and whether or not such investigation, litigation or other proceeding is brought by or on behalf of any Credit Party) related to the entering
into and/or performance of this Agreement or any other 

  

 -131- 

 
Credit Document or the use of any Letter of Credit or the proceeds of any Loans hereunder or the consummation of the Transaction or any other transactions
contemplated herein or in any other Credit Document or the exercise of any of their rights or remedies provided herein or in the other Credit Documents, or (b) the actual or alleged Release or threatened Release of Hazardous Materials in the
air, surface water or groundwater or on the surface or subsurface of any Real Property at any time owned, leased or operated by the Borrower or any of its Subsidiaries, the generation, storage, transportation, handling or disposal of Hazardous
Materials by the Borrower or any of its Subsidiaries at any location, whether or not owned, leased or operated by the Borrower or any of its Subsidiaries, the non-compliance by the Borrower or any of its Subsidiaries with any Environmental Law
(including applicable permits thereunder) applicable to any Real Property, or any Environmental Claim asserted against the Borrower, any of its Subsidiaries or any Real Property at any time owned, leased or operated by the Borrower or any of its
Subsidiaries, including, in each case, without limitation, the reasonable fees and disbursements of counsel and other consultants incurred in connection with any such investigation, litigation or other proceeding (but excluding any losses,
liabilities, claims, damages or expenses to the extent incurred by reason of the gross negligence or willful misconduct of the Person to be indemnified (as determined by a court of competent jurisdiction in a final and non-appealable decision)). To
the extent that the undertaking to indemnify, pay or hold harmless the Administrative Agent, the Syndication Agent, the Documentation Agent, any Joint Lead Arranger, any Joint Lead Bookrunner, any Issuing Lender or any Lender or any other Person set
forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, the Borrower shall make the maximum contribution to the payment and satisfaction of each of the indemnified liabilities which is permissible
under applicable law.  
 13.02. Right of Setoff. In addition to any rights now or hereafter granted under applicable law or
otherwise, and not by way of limitation of any such rights, upon the occurrence and during the continuance of an Event of Default, the Administrative Agent, the Collateral Agent, each Issuing Lender and each Lender is hereby authorized at any time
or from time to time, without presentment, demand, protest or other notice of any kind to any Credit Party or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and apply any and all deposits (general
or special) and any other Indebtedness at any time held or owing by the Administrative Agent, the Collateral Agent, such Issuing Lender or such Lender (including, without limitation, by branches and agencies of the Administrative Agent, the
Collateral Agent, such Issuing Lender or such Lender wherever located) to or for the credit or the account of the Borrower or any other Credit Party against and on account of the Obligations and liabilities of the Credit Parties to the
Administrative Agent, the Collateral Agent, such Issuing Lender or such Lender under this Agreement or under any of the other Credit Documents, including, without limitation, all interests in Obligations purchased by such Lender pursuant to
Section 13.04(b), and all other claims of any nature or description arising out of or connected with this Agreement or any other Credit Document, irrespective of whether or not the Administrative Agent, the Collateral Agent, such Issuing Lender
or such Lender shall have made any demand hereunder and although such Obligations, liabilities or claims, or any of them, shall be contingent or unmatured. 
 13.03. Notices. Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including telecopier communication) and mailed, telecopied or
delivered: if to any Credit Party, at the address 

  

 -132- 

 
specified opposite its signature below or in the other relevant Credit Documents; if to any Lender, at its address specified on Schedule XII; and if to the
Administrative Agent, at the Notice Office; or, as to any Credit Party or the Administrative Agent, at such other address as shall be designated by such party in a written notice to the other parties hereto and, as to each Lender, at such other
address as shall be designated by such Lender in a written notice to the Borrower and the Administrative Agent. All such notices and communications shall, when mailed, telecopied or sent by overnight courier, be effective when deposited in the
mails, delivered to the overnight courier or sent by telecopier, except that notices and communications to the Administrative Agent and the Borrower shall not be effective until received by the Administrative Agent or the Borrower, as the case may
be. 
 13.04. Benefit of Agreement; Assignments; Participations. (a) This Agreement shall be binding upon and inure to the
benefit of and be enforceable by the respective successors and assigns of the parties hereto, provided, however, the Borrower may not assign or transfer any of its rights, obligations or interest hereunder without the prior written
consent of the Lenders and, provided further, that, although any Lender may grant participations in its rights hereunder, such Lender shall remain a “Lender” for all purposes hereunder (and may not transfer or assign all or
any portion of its Commitments or Loans hereunder, except as provided in Sections 2.13 and 13.04(b)) and the participant shall not constitute a “Lender” hereunder and, provided further, that no Lender shall transfer or grant
any participation under which the participant shall have rights to approve any amendment to or waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver would (i) extend the final scheduled maturity of
any Loan, Note or Letter of Credit (unless such Letter of Credit is not extended beyond the Revolving Loan Maturity Date) in which such participant is participating, or reduce the rate or extend the time of payment of interest or Fees thereon
(except in connection with a waiver of applicability of any post-default increase in interest rates) or reduce the principal amount thereof (it being understood that any amendment or modification to the financial definitions in this Agreement or to
Section 13.07(a) shall not constitute a reduction in the rate of interest or Fees payable hereunder), or increase the amount of the participant’s participation over the amount thereof then in effect (it being understood that a waiver of
any Default or Event of Default or of a mandatory reduction in the Total Commitment shall not constitute a change in the terms of such participation, and that an increase in any Commitment (or the available portion thereof) or Loan shall be
permitted without the consent of any participant if the participant’s participation is not increased as a result thereof), (ii) consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement
or (iii) release all or substantially all of the Collateral under all of the Security Documents (except as expressly provided in the Credit Documents) supporting the Loans or Letters of Credit hereunder in which such participant is
participating. In the case of any such participation, the participant shall not have any rights under this Agreement or any of the other Credit Documents (the participant’s rights against such Lender in respect of such participation to be those
set forth in the agreement executed by such Lender in favor of the participant relating thereto) and all amounts payable by the Borrower hereunder shall be determined as if such Lender had not sold such participation. 
 (b) Notwithstanding the foregoing, any Lender (or any Lender together with one or more other Lenders) may (x) assign all or a portion of its
Commitments and related outstanding Obligations (or, if the Commitments with respect to the relevant Tranche have terminated, outstanding Obligations) hereunder to (i)(A) its parent company and/or any affiliate 

  

 -133- 

 
of such Lender which is at least 50% owned (directly or indirectly) by such Lender or its parent company or to any fund that invests in loans and is managed
or advised by such Lender or by an affiliate of such Lender or (B) to one or more other Lenders or any affiliate of any such other Lender which is at least 50% owned (directly or indirectly) by such other Lender or its parent company
(provided that any fund that invests in loans and is managed or advised by the same investment advisor of another fund which is a Lender (or by an Affiliate of such investment advisor) shall be treated as an affiliate of such other Lender for
the purposes of this sub-clause (x)(i)(B)), or (ii) in the case of any Lender that is a fund that invests in loans, any other fund that invests in loans and is managed or advised by the same investment advisor of any Lender or by an Affiliate
of such investment advisor or (y) assign all, or if less than all, a portion equal to at least $1,000,000 in the aggregate for the assigning Lender or assigning Lenders, of such Commitments and related outstanding Obligations (or, if the
Commitments with respect to the relevant Tranche have terminated, outstanding Obligations) hereunder to one or more Eligible Transferees (treating any fund that invests in loans and any other fund that invests in loans and is managed or advised by
the same investment advisor of such fund or by an Affiliate of such investment advisor as a single Eligible Transferee), each of which assignees shall become a party to this Agreement as a Lender by execution of an Assignment and Assumption
Agreement, provided that (i) at such time, Schedule I shall be deemed modified to reflect the Commitments and/or outstanding Loans, as the case may be, of such new Lender and of the existing Lenders, (ii) upon the surrender of the
relevant Notes by the assigning Lender (or, upon such assigning Lender’s indemnifying the Borrower for any lost Note pursuant to a customary indemnification agreement) new Notes will be issued, at the Borrower’s expense, to such new Lender
and to the assigning Lender upon the request of such new Lender or assigning Lender, such new Notes to be in conformity with the requirements of Section 2.05 (with appropriate modifications) to the extent needed to reflect the revised
Commitments and/or outstanding Loans, as the case may be, (iii) the consent of the Administrative Agent and, so long as no Default or Event of Default then exists and the Syndication Date has theretofore occurred, the Borrower, shall be
required in connection with any such assignment pursuant to clause (y) above (each of which consents shall not be unreasonably withheld or delayed), (iv) the Administrative Agent shall receive at the time of each such assignment, from the
assigning or assignee Lender, the payment of a non-refundable assignment fee of $3,500, and (v) no such transfer or assignment will be effective until recorded by the Administrative Agent on the Register pursuant to Section 13.15. To the
extent of any assignment pursuant to this Section 13.04(b), the assigning Lender shall be relieved of its obligations hereunder with respect to its assigned Commitments and outstanding Loans. At the time of each assignment pursuant to this
Section 13.04(b) to a Person which is not already a Lender hereunder and which is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for U.S. Federal income tax purposes, the respective assignee Lender
shall, to the extent legally entitled to do so, provide to the Borrower the appropriate Internal Revenue Service Forms (and, if applicable, a Section 5.04(b)(ii) Certificate) described in Section 5.04(b). To the extent that an assignment
of all or any portion of a Lender’s Commitments and related outstanding Obligations pursuant to Section 2.13 or this Section 13.04(b) would, at the time of such assignment, result in increased costs under Section 2.10, 3.06 or
5.04 from those being charged by the respective assigning Lender prior to such assignment, then the Borrower shall not be obligated to pay such increased costs (although the Borrower, in accordance with and pursuant to the other provisions of this
Agreement, shall 

  

 -134- 

 
be obligated to pay any other increased costs of the type described above resulting from changes after the date of the respective assignment). 
 (c) Nothing in this Agreement shall prevent or prohibit any Lender from pledging its Loans and Notes hereunder to a Federal Reserve Bank in support of
borrowings made by such Lender from such Federal Reserve Bank and, with prior notification to the Administrative Agent (but without the consent of the Administrative Agent or the Borrower), any Lender which is a fund may pledge all or any portion of
its Loans and Notes to its trustee or to a collateral agent or to another creditor providing credit or credit support to such Lender in support of its obligations to such trustee, such collateral agent, such other creditor or a holder of such
obligations, as the case may be. No pledge pursuant to this clause (c) shall release the transferor Lender from any of its obligations hereunder. 
 (d) Any Lender which assigns all of its Commitments and/or Loans hereunder in accordance with Section 13.04(b) shall cease to constitute a “Lender” hereunder, except with respect to indemnification
provisions under this Agreement (including, without limitation, Sections 2.10, 2.11, 3.06, 5.04, 12.06, 13.01 and 13.06), which shall survive as to such assigning Lender. 
 13.05. No Waiver; Remedies Cumulative. No failure or delay on the part of the Administrative Agent, the Collateral Agent, any Issuing Lender or any Lender in exercising any right, power or privilege hereunder
or under any other Credit Document and no course of dealing between the Borrower or any other Credit Party and the Administrative Agent, the Collateral Agent, any Issuing Lender or any Lender shall operate as a waiver thereof; nor shall any single
or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights, powers and
remedies herein or in any other Credit Document expressly provided are cumulative and not exclusive of any rights, powers or remedies which the Administrative Agent, the Collateral Agent, any Issuing Lender or any Lender would otherwise have. No
notice to or demand on any Credit Party in any case shall entitle any Credit Party to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Administrative Agent, the Collateral Agent, any
Issuing Lender or any Lender to any other or further action in any circumstances without notice or demand. 
 13.06. Payments Pro
Rata. (a) Except as otherwise provided in this Agreement, the Administrative Agent agrees that promptly after its receipt of each payment from or on behalf of the Borrower in respect of any Obligations hereunder, the Administrative Agent
shall distribute such payment to the Lenders entitled thereto (other than any Lender that has consented in writing to waive its pro rata share of any such payment) pro rata based upon their respective shares, if any, of
the Obligations with respect to which such payment was received. 
 (b) Each of the Lenders agrees that, if it should receive any amount
hereunder (whether by voluntary payment, by realization upon security, by the exercise of the right of setoff or banker’s lien, by counterclaim or cross action, by the enforcement of any right under the Credit Documents, or otherwise), which is
applicable to the payment of the principal of, or interest on, the Loans, Unpaid Drawings, Commitment Commission or Letter of Credit Fees, of a 

  

 -135- 

 
sum which with respect to the related sum or sums received by other Lenders is in a greater proportion than the total of such Obligation then owed and due to
such Lender bears to the total of such Obligation then owed and due to all of the Lenders immediately prior to such receipt, then such Lender receiving such excess payment shall purchase for cash without recourse or warranty from the other Lenders
an interest in the Obligations of the respective Credit Party to such Lenders in such amount as shall result in a proportional participation by all the Lenders in such amount, provided that if all or any portion of such excess amount is
thereafter recovered from such Lenders, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest. 
 (c) Notwithstanding anything to the contrary contained herein, the provisions of the preceding Sections 13.06(a) and (b) shall be subject to the express provisions of this Agreement which require, or permit,
differing payments to be made to Non-Defaulting Lenders as opposed to Defaulting Lenders. 
 13.07. Calculations; Computations.
(a) The financial statements to be furnished to the Lenders pursuant hereto shall be made and prepared in accordance with GAAP consistently applied throughout the periods involved (except as set forth in the notes thereto or as otherwise
disclosed in writing by the Borrower to the Lenders), provided that (i) to the extent expressly provided herein, certain calculations shall be made on a Pro Forma Basis, and (ii) for purposes of calculating the
Applicable Margin, Excess Cash Flow, financial ratios, financial covenants and all related definitions, the financial results of Unrestricted Subsidiaries shall be ignored. 
 (b) All computations of interest, Commitment Commission and other Fees hereunder shall be made on the basis of a year of 360 days (except for interest
calculated by reference to the Prime Lending Rate, which shall be based on a year of 365 or 366 days, as applicable) for the actual number of days (including the first day but excluding the last day; except that in the case of Letter of Credit Fees
and Facing Fees, the last day shall be included) occurring in the period for which such interest, Commitment Commission or Fees are payable. 
 13.08. GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE; WAIVER OF JURY TRIAL. (a) THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL, EXCEPT AS
OTHERWISE PROVIDED IN ANY MORTGAGE, BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK (WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES). ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER
CREDIT DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES IN THE DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, IN EACH CASE WHICH ARE LOCATED IN THE COUNTY OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF
THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT, THE BORROWER HEREBY IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. THE BORROWER HEREBY FURTHER IRREVOCABLY WAIVES
ANY CLAIM THAT ANY SUCH COURTS LACK PERSONAL JURISDICTION OVER THE 

  

 -136- 

 
BORROWER, AND AGREES NOT TO PLEAD OR CLAIM, IN ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT BROUGHT IN ANY OF
THE AFOREMENTIONED COURTS, THAT SUCH COURTS LACK PERSONAL JURISDICTION OVER THE BORROWER. THE BORROWER FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF
COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO THE BORROWER AT ITS ADDRESS SET FORTH OPPOSITE ITS SIGNATURE BELOW, SUCH SERVICE TO BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING. THE BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION
TO SUCH SERVICE OF PROCESS AND FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY ACTION OR PROCEEDING COMMENCED HEREUNDER OR UNDER ANY OTHER CREDIT DOCUMENT THAT SERVICE OF PROCESS WAS IN ANY WAY INVALID OR INEFFECTIVE. NOTHING
HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT, ANY LENDER OR THE HOLDER OF ANY NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE BORROWER IN
ANY OTHER JURISDICTION. 
 (b) THE BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE
OF ANY OF THE AFORESAID ACTIONS OR PROCEEDINGS ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT BROUGHT IN THE COURTS REFERRED TO IN CLAUSE (a) ABOVE AND HEREBY FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO PLEAD
OR CLAIM IN ANY SUCH COURT THAT ANY SUCH ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. 
 (c)
EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY
OR THEREBY. 
 13.09. Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto

prepayment, repayment or commitment reduction as a result of the actions described below, alter the required application of any prepayments or repayments (or commitment reduction), as between the various Tranches, pursuant to Section 5.02(g)
(it being understood, however, that the Required Lenders may waive, in whole or in part, any such prepayment, repayment or commitment reduction, so long as the application, as amongst the various Tranches, of any such prepayment, repayment or
commitment reduction which is still required to be made is not altered), (7) without the consent of the Majority Lenders of the respective Tranche affected thereby, amend the definition of Majority Lenders (it being understood that, with the

each such non-consenting Lender or Lenders (or, at the option of the Borrower, if the respective Lender’s consent is required with respect to less than all Tranches of Loans (or related Commitments), to replace only the Revolving Loan
Commitments and/or Loans of the respective non-consenting Lender which gave rise to the need to obtain such Lender’s individual consent) with one or more Replacement Lenders pursuant to Section 2.13 so long as at the time of such
replacement, each such Replacement Lender consents to the proposed change, waiver, discharge or termination or (B) terminate such non-consenting Lender’s Revolving Loan Commitment (if such Lender’s consent is required as a result of

replaced in full at such time through the addition of new Lenders or the increase of the Commitments and/or 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), the Required Lenders (determined after giving effect to the proposed action) shall specifically consent thereto, provided further, that the Borrower shall not have the right to replace a Lender, terminate its
Commitment or repay its Loans solely as a result of the exercise of such Lender’s rights (and the withholding of any required consent by such Lender) pursuant to the second proviso to Section 13.12(a). 
 (c) Notwithstanding anything to the contrary contained in clause (a) above of this Section 13.12, the Borrower, the Administrative Agent and
each Incremental Term Loan Lender may, in accordance with the provisions of Section 2.14, enter into an Incremental Term Loan Commitment Agreement, provided that after the execution and delivery by the Borrower, the Administrative Agent

Section 13.12. 
 13.13. Survival. All indemnities set forth herein including, without limitation, in Sections 2.10, 2.11, 3.06,
5.04, 12.06 and 13.01 shall survive the execution, delivery and termination of this Agreement and the Notes and the making and repayment of the Obligations. 
 13.14. Domicile of Loans. Each Lender may transfer and carry its Loans at, to or for the account of any office, Subsidiary or Affiliate of such Lender. Notwithstanding anything to the contrary contained
herein, to the extent that a transfer of Loans pursuant to this Section 13.14 would, at the time of such transfer, result in increased costs under Section 2.10, 2.11, 3.06 or 5.04 from those being charged by the respective Lender prior to
such transfer, then the Borrower shall not be obligated to pay such increased costs (although the Borrower shall be obligated to pay any other increased costs of the type described above resulting from changes in any applicable law, treaty,
governmental rule, regulation, guidelines or order, or in the interpretation thereof, after the date of the respective transfer). 
 13.15.
Register. The Borrower hereby designates the Administrative Agent to serve as its agent, solely for purposes of this Section 13.15, to maintain a register (the “Register”) on which it will maintain a list of the names of
each of the Lenders and record the Commitments of each of the Lenders, the Loans made by each of the Lenders and each repayment in respect of the principal amount of the Loans of each Lender. The entries in the Register shall, in the absence of
manifest error, be conclusive, and the Borrower, the Administrative Agent and the Lenders shall 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. With respect to any Lender, the transfer of the Commitments of such Lender and the rights to the principal of, and interest on, any Loan made pursuant to such Commitments shall not be effective until such
transfer is recorded on the Register maintained by the Administrative Agent with respect to ownership of such Commitments and Loans and prior to such recordation all amounts owing to the transferor with respect to such Commitments and Loans shall
remain owing to the transferor. The registration of 

  

 -140- 

 
assignment or transfer of all or part of any Commitments and Loans shall be recorded by the Administrative Agent on the Register only upon the acceptance by
the Administrative Agent of a properly executed and delivered Assignment and Assumption Agreement pursuant to Section 13.04(b). Coincident with the delivery of such an Assignment and Assumption Agreement to the Administrative Agent for
acceptance and registration of assignment or transfer of all or part of a Loan, or as soon thereafter as practicable, the assigning or transferor Lender shall surrender the Note (if any) evidencing such Loan, and thereupon one or more new Notes in
the same aggregate principal amount shall be issued to the assigning or transferor Lender and/or the new Lender at the request of any such Lender. Any provision of Incremental Term Loan Commitments pursuant to Section 2.14 shall be recorded by
the Administrative Agent on the Register only upon the acceptance by the Administrative Agent of a properly executed and delivered Incremental Term Loan Commitment Agreement. The Borrower agrees to indemnify the Administrative Agent from and against
any and all losses, claims, damages and liabilities of whatsoever nature which may be imposed on, asserted against or incurred by the Administrative Agent in performing its duties under this Section 13.15. 
 13.16. Confidentiality. (a) Subject to the provisions of clause (b) of this Section 13.16, each Lender agrees that it will maintain
as confidential and not disclose without the prior written consent of the Borrower (other than to such Lender’s employees, managers, trustees, pledgees, auditors, advisors, counsel or representatives or to another Lender if such Lender or such
Lender’s holding or parent company in its sole discretion determines that any such party should have access to such information, provided such Persons shall be subject to the provisions of this Section 13.16 to the same extent as
such Lender) any information with respect to the Borrower or any of its Subsidiaries which is now or in the future furnished pursuant to this Agreement or any other Credit Document, provided that any Lender may disclose any such information
(i) as has become generally available to the public other than by virtue of a breach of this Section 13.16(a) by the respective Lender, (ii) as may be required or appropriate in any report, statement or testimony submitted to any
municipal, state or Federal regulatory body or self-regulatory body having or claiming to have jurisdiction over such Lender or to the Federal Reserve Board or the Federal Deposit Insurance Corporation or similar organizations (whether in the United
States or elsewhere) or their successors, (iii) as may be required or appropriate in respect to any summons or subpoena or in connection with any litigation, (iv) in order to comply with any law, order, regulation or ruling applicable to
such Lender, (v) to the Administrative Agent or the Collateral Agent, (vi) to any direct or indirect contractual counterparty in any swap, hedge or similar agreement (or to any such contractual counterparty’s professional advisor), so
long as such contractual counterparty (or such professional advisor) agrees to be bound by the provisions of this Section 13.16 prior to its receipt of any such information, (vii) to any prospective or actual transferee or participant in
connection with any contemplated transfer or participation of any of the Notes or Commitments or any interest therein by such Lender, provided that such prospective transferee agrees to be bound by the confidentiality provisions contained in
this Section 13.16 and (viii) to any rating agency when required by it (it being understood that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any such information received by it from
such Lender). 
 (b) The Borrower hereby acknowledges and agrees that each Lender may share with any of its affiliates, and such affiliates
may share with such Lender (and, in each case, any of their respective employees, managers, trustees, pledgees, auditors, advisors, counsel or 

  

 -141- 

 
representatives), any information related to the Borrower or any of its Subsidiaries (including, without limitation, any non-public customer information
regarding the creditworthiness of the Borrower and its Subsidiaries), provided such Persons shall be subject to the provisions of this Section 13.16 to the same extent as such Lender. 
 13.17. Patriot Act. Each Lender subject to the USA PATRIOT ACT (Title 111 of Pub. L. 107-56 (signed into law October 26, 2001)) (the
“Patriot Act”) hereby notifies the Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrower and the other Credit Parties and other
information that will allow such Lender to identify the Borrower and the other Credit Parties in accordance with the Patriot Act. 
 13.18.
Post-Closing Actions. Notwithstanding anything to the contrary contained in this Agreement or in the other Credit Documents, the parties hereto acknowledge and agree that: 
 (a) UCC Filings; Filings with respect to Intellectual Property; etc. The Borrower and its Subsidiaries are not required to have
filed (or cause to have filed) on or prior to the Initial Borrowing Date Financing Statements (Form UCC-1) or any filings with the United States Patent and Trademark Office or the United States Copyright Office necessary to perfect the security
interest purported to be created by the Security Agreement or the Pledge Agreement, as applicable. Not later than the 10th day after the Initial Borrowing Date, the Borrower and its Subsidiaries shall have filed (or cause to have filed) all of such
Financing Statements (Form UCC-1) and any filings with the United States Patent and Trademark Office or the United States Copyright Office necessary to perfect the security interest purported to be created by the Security Agreement or the Pledge
Agreement, as the case may be. 
 (b) Landlord Waivers. The Borrower and its Subsidiaries shall use all commercially
reasonable efforts to obtain, on or before the date that is 120 days after the Initial Borrowing Date, an executed landlord waiver for the benefit of the Administrative Agent for properties leased by the Borrower or any Subsidiary Guarantor in which
any Switching Equipment is located on the Initial Borrowing Date. 
 (c) Share Certificates; Certificate of Good
Standing. No later than 5 Business Days after the Initial Borrowing Date, the Borrower shall deliver (or cause to be delivered) to the Administrative Agent (i) stock certificates for each Subsidiary of US LEC, to the extent required by

 -142- 

 All conditions precedent and representations contained in this Agreement and the other Credit Documents
shall be deemed modified to the extent necessary to effect the foregoing (and to permit the taking of the actions described above within the time periods required above, rather than as elsewhere provided in the Credit Documents), provided
that (x) to the extent any representation and warranty would not be true because the foregoing actions were not taken on the Borrowing Date, the respective representation and warranty shall be required to be true and correct in all material
respects at the time the respective action is taken (or was required to be taken) in accordance with the foregoing provisions of this Section 13.18 and (y) all representations and warranties relating to the Security Documents shall be
required to be true immediately after the actions required to be taken by this Section 13.18 have been taken (or were required to be taken). The acceptance of the benefits of each Credit Event shall constitute a representation, warranty and
covenant by the Borrower to each of the Lenders that the actions required pursuant to this Section 13.18 will be, or have been, taken within the relevant time periods referred to in this Section 13.18 and that, at such time, all
representations and warranties contained in this Agreement and the other Credit Documents shall then be true and correct without any modification pursuant to this Section 13.18, and the parties hereto acknowledge and agree that the failure to
take any of the actions required above, within the relevant time periods required above, shall give rise to an immediate Event of Default pursuant to this Agreement.

sole securities entitled to the benefits of this Agreement. 
 (b) For the purposes of this Agreement, Registrable Common Shares held in the
name of any Stockholder, other than each Management Stockholder, shall cease to be Registrable Common Shares (and such Stockholder shall cease to have any registration rights with respect to such securities under this Agreement), and Registrable
Common Shares held by any Management Stockholder shall cease to be Registrable Common Shares entitled to demand registration rights pursuant to Section 3 (provided that such Management Stockholder shall thereafter continue to have piggyback
registration rights with respect to such securities pursuant to Section 4), on the date and to the extent that (i) a Registration Statement covering such Registrable Common Shares has been declared effective under the Securities Act and
such Registrable Common Shares have been disposed of pursuant to such effective Registration Statement, (ii) such Registrable Common Shares have been sold or transferred in accordance with the requirements of Rule 144 or Rule 145(d),
(iii) such Registrable Common Shares have been otherwise transferred or disposed of, certificates therefor not bearing a legend restricting further transfer or disposition thereof shall have been delivered by the Company and, at such time,

Warrant Shares shall not cease to be Registrable Common Shares until the Stockholder thereof has had the right to include such Warrant Shares in, and dispose of such Warrant Shares pursuant to, at least one registration, regardless of whether such
Stockholder elects to include such Warrant 

  

 -6- 

 
Shares in, or dispose of such Warrant Shares pursuant to, such registration. If a Stockholder wishes to dispose of Warrant Shares subject to issuance upon

 3.
Demand Registration Rights. 
 (a) At any time following the date that is 120 days following the Closing Date, upon the written
request of any Demand Stockholder (the “Initiating Demand Stockholder”) that the Company effect the registration under the Securities Act of all or part of such Initiating Demand Stockholder’s Registrable Common Shares (which
written request shall specify the aggregate number of Registrable Common Shares requested to be registered), the Company shall (i) as soon as reasonably practicable, but no later than 45 Business Days after its receipt of such request, file
with the SEC a Registration Statement with respect to such requested registration (or, if the Company shall be legally prohibited from making such a filing or if financial statements required to be included in such a filing are not reasonably
available, in each case, within 45 Business Days after its receipt of such request, as soon thereafter as is legally permissible or as such financial statements are reasonably available) and (ii) within seven Business Days after its receipt of
such request, notify in writing all other Demand Stockholders and all Warrant Stockholders (collectively, the “Non-Initiating Stockholders”) of such request and indicate in such notice the planned initial filing date of such
Registration Statement. Subject to reduction pursuant to Section 5(a), such Registration Statement shall cover the Registrable Common Shares requested by the Initiating Demand Stockholder to be registered and such other Registrable Common
Shares as the Non-Initiating Stockholders shall request, by written notice to the Company given no later than ten Business Days prior to such planned initial filing date, to be registered. 
 (b) Notwithstanding the provisions of Section 3(a), the Company shall not be required to take any action pursuant to this Section 3:

 (i) if, prior to the date of a request by Mr. Chesonis pursuant to Section 3(a), the Company shall have
effected two registrations pursuant to Section 3(a) at the request of Mr. Chesonis; 
 (ii) if, prior to the date of
a request by the US LEC Demand Stockholder pursuant to Section 3(a), the Company shall have effected two registrations pursuant to Section 3(a) at the request of the US LEC Demand Stockholder; 
  

 -7- 

 (iii) if, prior to the date of a request by the Blackstone Stockholder pursuant to
Section 3(a), the Company shall have effected one registration pursuant to Section 3(a) at the request of the Blackstone Stockholder; 
 (iv) if, prior to the date of a request by the MDCP Stockholder pursuant to Section 3(a), the Company shall have effected one registration pursuant to Section 3(a) at the request of the MDCP
Stockholder; 
 (v) if the Company shall have effected a registration pursuant to Section 3(a) within the 180-day period
immediately preceding the date of such request; 
 (vi) if the Registrable Common Shares of the Initiating Demand
Stockholder which the Company shall have been requested to register shall have an anticipated aggregate offering price of less than $20,000,000, as determined in good faith by the Company at the time of its receipt of a request for registration
pursuant to Section 3(a), unless such registration request is for all remaining Registrable Common Shares held by such Initiating Demand Stockholder; or 
 (vii) during the pendency of any Blackout Period; 
 provided, however, that the Company shall be permitted to satisfy its obligations under Section 3(a) by amending (to the extent permitted by applicable law) within 45 days after a written request for
registration, any Registration Statement previously filed by the Company under the Securities Act so that such Registration Statement (as amended) shall permit the disposition pursuant to an Underwritten Offering of all of the Registrable Common
Shares for which a demand for registration has been made under Section 3(a). If the Company shall so amend a previously filed Registration Statement, it shall be deemed to have effected a registration for purposes of this Section 3.

 (c) The Initiating Demand Stockholder delivering a request pursuant to Section 3(a) may distribute the Registrable Common Shares
covered by such demand only by means of an Underwritten Offering. 
 (d) Subject to Section 3(e), and notwithstanding the last
sentence of Section 3(b), a registration requested pursuant to this Section 3 shall not be deemed to be effected for purposes of this Section 3 if (i) the Registration Statement for such registration has not been declared
effective by the SEC or has not become effective in accordance with the Securities Act and the rules and regulations thereunder, or (ii) the Initiating Demand Stockholder shall not be entitled to include in such registration at least 75% of the
Registrable Common Shares that the Initiating Demand Stockholder requested pursuant to Section 3(a) to be so included in such registration. 
 (e) The Initiating Demand Stockholder may, at any time prior to the effective date of the Registration Statement relating to such registration, revoke such request by providing a written notice to the Company revoking such request. The
Company shall be 

  

 -8- 

 
deemed to have effected a registration pursuant to Section 3(a) in the case of any such revocation unless the Initiating Demand Stockholder reimburses
the Company for all Registration Expenses incurred by the Company with respect to such revoked request. Except as otherwise contemplated by the immediately preceding sentence, no revocation pursuant to this Section 3(e) shall relieve the
Company of its obligation hereunder to pay the Registration Expenses in connection with any such request. 
 (f) Any request or notice
furnished by an Initiating Demand Stockholder pursuant to this Section 3 shall only be effective if signed by the Stockholders holding a Majority of the Registrable Common Shares held by all of the Stockholders that collectively constitute such
Initiating Demand Stockholder. Any such properly furnished request or notice shall be binding upon each Stockholder holding Registrable Common Shares that constitutes a part of such Initiating Demand Stockholder. 
 4. Piggy-Back Registration Rights. 
 (a) If the Company shall propose to file a Registration Statement under the Securities Act relating to a public offering of Common Stock or other equity securities (other than in connection with an Excluded Registration) for the
Company’s own account or for the account of any holder or holders of Common Stock or other securities (including an Initiating Demand Stockholder) pursuant to the exercise of registration rights (the Person or the Persons, collectively, for
whose account such a Registration Statement is proposed to be filed, the “Initiating Securityholder”), in each case, on a registration form and in a manner that would permit the registration of Registrable Common Shares for sale to
the public under the Securities Act, the Company shall (i) give written notice at least 15 Business Days prior to the filing thereof to each Stockholder holding Registrable Common Shares, specifying the approximate date on which the Company
proposes to file such Registration Statement and advising such Stockholder of its right to have any or all of the Registrable Common Shares of such Stockholder included among the securities to be covered thereby, and (ii) at the written request
of any such Stockholder given to the Company within ten Business Days after written notice from the Company has been given to the Stockholder, include among the securities covered by such Registration Statement the number of Registrable Common
Shares which such Stockholder (a “Requesting Stockholder”) shall have requested be so included (subject, however, to reduction, in accordance with the applicable provisions of Section 5). Notwithstanding the foregoing, if the
Initiating Securityholder shall be an Initiating Demand Stockholder that has delivered a written request for registration pursuant to Section 3(a), the Company shall provide written notice of the proposed filing of such Registration Statement
to all other Demand Stockholders and the Warrant Stockholders then eligible to registration rights pursuant to Section 3 in accordance with Section 3(a), rather than this Section 4(a). 
 (b) Nothing in this Section 4 shall create any liability on the part of the Company to any Stockholder holding Registrable Common Shares if for
any reason the Company shall decide not to file, or to delay the filing of, a Registration Statement proposed to be filed under Section 4(a) or to withdraw such Registration Statement subsequent to its filing, regardless of any action
whatsoever that a Stockholder may have taken, whether as a result of the issuance by the Company of any notice hereunder or otherwise, provided, however, that the Company shall not be relieved of its obligation hereunder to pay the Registration
Expenses in connection with any such filing or proposed filing. 
  

 -9- 

 5. Cutbacks. 
 (a) Offerings by the Demand Stockholders. In connection with any offering covered by a Registration Statement filed pursuant to Section 3, if the lead managing underwriters give written notice (a
“Cutback Notice”) to the Company (it being understood that the Company shall as soon as reasonably practicable deliver copies of any such notice to all Stockholders who have requested to include Registrable Common Shares in such
offering) that, in their reasonable and good faith opinion, the Registrable Common Shares and other shares of Common Stock and other securities requested to be included in such offering exceed the number which can be sold in such offering without
being likely to have a significant adverse effect on the offering price, timing or distribution of the securities offered or the market for the class of securities offered or for the Common Stock (an “Adverse Offering Effect”), then
the Company shall include in such offering only the number of Registrable Common Shares and other shares of Common Stock that, in the good faith opinion of such underwriters, can be included without having an Adverse Offering Effect. In such event,
the Registrable Common Shares and other shares of Common Stock and other securities to be included in such offering shall consist of (i) first, all of the Registrable Common Shares that the Demand Stockholders and Warrant Stockholders propose
to sell pursuant to Section 3 (with any reduction in such number being allocated among the Demand Stockholders and the Warrant Stockholders pro-rata based on the number, as of the date of delivery of the first Cutback Notice delivered to the
Stockholders in connection with such offering, of Registrable Common Shares requested by the Demand Stockholders and the Warrant Stockholders to be included in such offering) and (ii) second, the number of Registrable Common Shares that the
Other Stockholders propose to sell pursuant to Section 4 that, in the reasonable and good faith opinion of such lead managing underwriters, can be sold without having an Adverse Offering Effect (with any reduction in such number being allocated
among the Other Stockholders pro-rata based on the number, as of the date of delivery of the first Cutback Notice delivered to the Stockholders in connection with such offering, of Registrable Common Shares requested by the Other Stockholders to be
included in such offering). No other securities shall be included in such offering except to the extent that, in the reasonable and good faith opinion of such lead managing underwriters, such securities can be included without having an Adverse
Offering Effect. 
 (b) Offerings by the Company. Each Stockholder who wishes to include Registrable Common Shares pursuant to
Section 4(a) in any offering covered by a Registration Statement filed by the Company relating to a public offering of Common Stock or other equity securities for its own account (other than in connection with an Excluded Registration) shall
have the right to include such Registrable Common Shares in any such offering only to the extent that the inclusion of such Registrable Common Shares can be included without having an Adverse Offering Effect. In connection with the inclusion of
Registrable Common Shares pursuant to Section 4(a) in any such offering by the Company, if the lead managing underwriter or underwriters in an Underwritten Offering delivers a Cutback Notice to the Company (it being understood that the Company
shall as soon as 

  

 -10- 

 
reasonably practicable deliver copies of any such notice to all Stockholders who have requested to include Registrable Common Shares in such offering) or (if
the offering shall not be an Underwritten Offering) the Company delivers a Cutback Notice to the Stockholders, then the Company shall include in such offering, in addition to the securities the Company proposes to sell for its own account, only the
aggregate number of Registrable Common Shares that, in the reasonable and good faith opinion of such lead managing underwriter or underwriters or (if the offering shall not be an Underwritten Offering) the Company, can be included without having an
Adverse Offering Effect. Such aggregate number of Registrable Common Shares to be included in such offering shall be allocated pro-rata among the Stockholders who have requested Registrable Common Shares be so included based on the number, as of the
date of delivery of the first Cutback Notice delivered to the Stockholders in connection with such offering, of Registrable Common Shares requested by the Stockholders to be included in such offering. No other securities shall be included in such
offering except to the extent that, in the reasonable and good faith opinion of such lead managing underwriter or underwriters or (if the offering shall not be an Underwritten Offering) the Company, such securities can be included without having an
Adverse Offering Effect. 
 (c) Other Offerings In connection with any offering described in Section 4(a), other than an
offering covered by a Registration Statement filed pursuant to Section 3 or an offering by the Company for its own account, if the lead managing underwriter or underwriters (if the offering shall be an Underwritten Offering) or the Initiating
Securityholder (if the offering shall not be an Underwritten Offering) delivers a Cutback Notice to the Company (it being understood that the Company shall as soon as reasonably practicable deliver copies of any such notice to all Stockholders who
have requested to include Registrable Common Shares in such offering), then the Company shall include in such offering only the number of Registrable Common Shares and other securities that, in the good faith opinion of such underwriter or
underwriters or (if the offering shall not be an Underwritten Offering) the Initiating Securityholder, can be included without having an Adverse Offering Effect. In such event, the Registrable Common Shares and other securities to be included in
such offering shall consist of (i) first, all of the Other Registrable Securities that the Initiating Securityholder propose to sell, and (ii) second, all of the Registrable Common Shares that the Stockholders propose to sell pursuant to
Section 4 that, in the reasonable and good faith opinion of such lead managing underwriter or underwriters or (if the offering shall not be an Underwritten Offering) the Initiating Securityholder, can be sold without having an Adverse Offering
Effect (with any reduction in such number being allocated pro-rata based on the number, as of the date of delivery of the first Cutback Notice delivered to the Stockholders, of Registrable Common Shares requested by the Stockholders to be included
in such offering). No other securities shall be included in such offering except to the extent that, in the reasonable and good faith opinion of such lead managing underwriter or underwriters or (if the offering shall not be an Underwritten
Offering) the Company, such securities can be included without having an Adverse Offering Effect. 
 (d) Existing Registration Rights.
Notwithstanding any provision of this Agreement, to the extent that any holder of Other Registrable Securities as of the date of this Agreement shall have rights with respect to any offering that are inconsistent with the rights of the Stockholders
pursuant to this Agreement with respect to such offering, the rights of the 

  

 -11- 

 
Stockholders under this Agreement shall be modified so that the rights of the Stockholders under this Agreement with respect to such offering shall not be
inconsistent with the rights of such holder of Other Registrable Securities with respect to such offering. 
 6. Selection of
Underwriters. 
 (a) In connection with any Registration Statement filed pursuant to Section 3, the Initiating Demand Stockholder
shall have the right to select a lead managing underwriter or underwriters to administer such offering, which lead managing underwriter or underwriters shall be reasonably satisfactory to the Company; provided, however, that the Company shall have
the right to select a co-managing underwriter or underwriters for such offering, which co-managing underwriter or underwriters shall be reasonably satisfactory to the Initiating Demand Stockholder. 
 (b) Any selection or determination made by an Initiating Demand Stockholder pursuant to Section 6(a) shall only be effective if signed by the
Stockholders holding a Majority of the Registrable Common Shares held by all of the Stockholders that collectively constitute such Initiating Demand Stockholder. Any such properly made selection or determination shall be binding upon each
Stockholder holding Registrable Common Shares that constitutes a part of such Initiating Demand Stockholder. 
 7. Blackout Periods;
Holdback. 
 (a) If the Company determines that the registration and distribution of Registrable Common Shares (i) would
materially impede, delay, interfere with or otherwise adversely affect any pending financing, registration of securities by the Company in a primary offering for its own account, acquisition, corporate reorganization, debt restructuring or other
significant transaction involving the Company or (ii) would require disclosure of non-public material information that the Company has a bona fide business purpose for preserving as confidential, as determined by the Company’s Board
of Directors in good faith, the Company shall be entitled to defer the filing or effectiveness of a Registration Statement, or to suspend the use of an effective Registration Statement, for the shortest period of time reasonably required (each such
period, a “Blackout Period”); provided that the Company shall not be entitled to obtain deferrals or suspensions under (x) clause (i) of this Section 7(a), for more than an aggregate of 120 days in any 12-month period
or (y) clause (ii) of this Section 7(a), for more than 30 days on any one occasion, on more than two occasions in any 12-month period or for more than an aggregate of 60 days in any 12-month period. The Company shall notify each
Stockholder of the expiration or earlier termination of a Blackout Period and, as soon as reasonably practicable after such expiration or termination, shall amend or supplement any effective Registration Statement to the extent necessary to permit
the Stockholders to resume use thereof in connection with the offer and sale of their Registrable Common Shares in accordance with applicable law. 
 (b) In the case of an Underwritten Offering of securities of the Company, each Stockholder agrees, if requested in writing by the lead managing underwriter of such Underwritten Offering, that it shall not effect any public sale or
public distribution (but 

  

 -12- 

 
excluding any sales made in accordance with (i) Rule 144 and Rule 145(d), in each case, to the extent applicable to such sales, and (ii) the volume
limitations of Rule 144(e), regardless of whether applicable to such sales) of any Registrable Common Shares or Similar Securities held by such Stockholder during the period beginning seven days before, and ending 90 days (or such shorter
period as may be permitted by such lead managing underwriter) after, the effective date of the Registration Statement filed in connection with such registration, except for Registrable Common Shares included in such registration. If requested by
such managing underwriter, each Stockholder shall enter, and shall use commercially reasonable efforts to ensure that all Affiliates of such Stockholder holding Registrable Common Shares or Similar Securities enter, into a lock-up agreement with the
applicable underwriters that is consistent with the agreement in the preceding sentence. 
 (c) Notwithstanding any provision of
Section 7(a) or 7(b) to the contrary, the cumulative period of any Blackout Periods pursuant to Section 7(a) and of any holdbacks pursuant to Section 7(b) shall not exceed, in the aggregate, 120 days in any 12-month period.

 (d) In the case of any Underwritten Offering of Registrable Common Shares initiated by a Demand Stockholder pursuant to
Section 3(a), the Company agrees, if requested in writing by the lead managing underwriters of such Underwritten Offering, not to effect (or register for sale) any public sale or distribution of any securities that are Similar Securities for
the Company’s own account during the period beginning seven days before, and ending 90 days (or such lesser period as may be permitted by such lead managing underwriter) after, the effective date of the Registration Statement filed in
connection with such registration, except for securities of the Company to be offered for the Company’s account in such Underwritten Offering. Notwithstanding the foregoing, the Company may effect a public sale or distribution of Common Stock
and other securities that are Similar Securities for the Company’s own account during the period described above (i) pursuant to registrations on Forms S-4 or S-8 or any successor registration forms, (ii) as part of any registration
of securities for offering and sale to employees, directors or consultants of the Company pursuant to any stock plan or other benefit plan arrangement or (iii) in an amount that shall not exceed the volume limitations set forth in Rule
144(e)(1). The Company agrees to use commercially reasonable efforts to obtain from directors or executive officers of the Company who holds Common Stock or other securities that are Similar Securities an agreement not to effect any public sale or
distribution of such Similar Securities (other than any sale under Rule 144 or Rule 145(d)) for the account of such director or executive officer during any period referred to in this Section 7(d), except as part of any Underwritten Offering
contemplated in this Section 7(d). 
 8. Registration Procedures. In connection with the registration obligations of the Company
under Sections 3 and 4, the Company shall: 
 (a) prepare and file with the SEC a Registration Statement with respect to such Registrable
Common Shares on any registration form adopted by the SEC for which the Company then qualifies or which counsel for the Company shall deem appropriate, and which form shall be available for the sale of the Registrable Common Shares in accordance
with the intended methods of distribution thereof, and use commercially reasonable efforts to 

  

 -13- 

 
cause such Registration Statement to become and remain effective; provided that, at least five Business Days prior to filing a Registration Statement or
Prospectus or any amendment or supplement thereto, the Company shall furnish to a single counsel selected by (x) Stockholders holding a Majority of the Registrable Common Shares being registered on behalf of the Initiating Demand Stockholder,
in the case of a registration pursuant to Section 3(a), or (y) Stockholders holding a Majority of the Registrable Common Shares being registered on behalf of all Stockholders, in the case of a registration made pursuant to
Section 4(a) by a Person other than an Initiating Demand Stockholder, copies of such Registration Statement or Prospectus (or amendment or supplement) as proposed to be filed (including, upon the request of such counsel, documents to be
incorporated by reference therein), which documents shall be subject to the reasonable review and comments of such counsel and the Stockholders holding the Registrable Common Shares included or to be included in such Registration Statement during
such five-Business-Day period; 
 (b) prepare and file with the SEC amendments
and post-effective amendments to such Registration Statement and such amendments and supplements to the Prospectus used in connection therewith as may be necessary to maintain the effectiveness of such registration or as may be required by the

date on which the Registrable Common Shares covered by such Registration Statement cease to be Registrable Common Shares or have been sold or withdrawn and (ii) subject to Sections 8(e) and 8(k), in the case of a Registration Statement filed
pursuant to Section 3, for at least 120 days plus such longer period (not to exceed 90 days after the 120th
day) as, in the opinion of counsel for the underwriter or underwriters of such Underwritten Offering, is required by law for the delivery of a Prospectus in connection with the sale of Registrable Common Shares by an underwriter or dealer, and cause
the Prospectus as so amended and supplemented to be filed pursuant to Rule 424 under the Securities Act, and otherwise use reasonable best efforts to comply with the provisions of the Securities Act with respect to the disposition of all securities
covered by such Registration Statement until such time as is specified in clause (i) or (ii) above, as the case may be;

Section 9(b)) of the Prospectus or any amendment or supplement thereto in connection with such disposition); 
 (d) use
commercially reasonable efforts to register or qualify such Registrable Common Shares covered by such Registration Statement under such other securities or blue sky laws of such jurisdictions as each Stockholder shall reasonably request, and to do
any and all other acts and things which may be reasonably necessary to enable such Stockholder to consummate the disposition in such jurisdictions of the Registrable Common Shares held by such Stockholder, except that the Company shall not be
required for any such

 (e) promptly notify each Stockholder holding any such Registrable Common Shares covered by such Registration Statement, at any time when a Prospectus relating thereto is required to be delivered under the
Securities Act within the applicable period referred to in Section 8(b), that the Company has become aware that the Prospectus included in such Registration Statement, as then in effect, includes an untrue statement of material fact or omits to
state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing (the period during which the Stockholders are required in such case pursuant to
Section 9(b) to refrain from effecting public sales or distributions of Registrable Common Shares referred to herein as a “Section 8(e) Period”), and prepare and furnish to such Stockholder, as soon as reasonably practicable,
without charge to such Stockholder, a reasonable number of copies of an amendment to such Registration Statement or supplement to such related Prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable
Common Shares, such Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then
existing; provided that if the Company gives such notice, the Company shall extend the period during which such Registration Statement shall be maintained effective as provided in Section 8(b) by the number of days in the Section 8(e)
Period; 
 (f) promptly notify each Stockholder holding Registrable Common Shares covered by such Registration Statement at any time:

customarily covered in opinions requested in comparable Underwritten Offerings; 
 (iii) use commercially reasonable

such denominations and registered in such names as the managing underwriter or underwriters or agents, if any, or such Stockholders, may request; 
 (j) if reasonably requested by the managing underwriter or underwriters or a Stockholder holding Registrable Common Shares being sold in connection with an Underwritten Offering, incorporate in a Prospectus supplement or post-effective
amendment to the Registration Statement such information as the managing underwriters and the Stockholders holding a Majority of the Registrable Common Shares being sold by all Stockholders agree should be included therein relating to the plan of
distribution with respect to such Registrable Common Shares, including information with respect to the amount of Registrable Common Shares being sold to such underwriters, the purchase price being paid therefor by such underwriters and any other
terms of the Underwritten Offering of the Registrable Common Shares to be sold in such offering and make all required filings of such Prospectus supplement or post-effective amendment upon being notified of the matters to be incorporated in such
Prospectus supplement or post-effective amendment; 
 (k) in the event of the issuance of any stop order of which the Company is aware
suspending the effectiveness of the Registration Statement, or of any order suspending or preventing the use of any related Prospectus or suspending the qualification of any Registrable Common Shares included in the Registration Statement for sale
in any 

  

 -16- 

 
jurisdiction, use commercially reasonable efforts to obtain at the earliest practicable time the withdrawal of such stop order or other order (the period
between the issuance and withdrawal of any stop order or other order referred to herein as a “Section 8(k) Period”); provided that the Company shall extend the period during which such Registration Statement will be maintained
effective as provided in Section 8(b) by the number of days in the Section 8(k) Period; 
 (l) use reasonable best efforts to
cause all Common Stock covered by such Registration Statement to be listed on any securities exchange on which the Common Stock is then listed, if the Common Stock covered by such Registration Statement is not already so listed and if such listing
is then permitted under the rules of such securities exchange; 
 (m) in the case of an Underwritten Offering, cause the senior
executive officers of the Company to participate in the customary “road show” presentations that may be reasonably requested by the lead managing underwriter in any such Underwritten Offering and otherwise to cooperate with and participate
in customary selling efforts related thereto; 
 (n) not later than the effective date of the applicable Registration Statement, provide
a CUSIP number for all Registrable Common Shares and, unless such Registrable Common Shares shall be registered in book-entry form, provide the applicable transfer agent and registrar for such Registrable Common Shares with printed certificates for
the Registrable Common Shares, which certificates shall be in a form eligible for deposit with The Depository Trust Company; 
 (o) provide and cause to be maintained a transfer agent and registrar for all Registrable Common Shares covered by the applicable Registration Statement from and after a date not later than the effective date of such Registration
Statement; and 
 (p) make available upon reasonable notice at reasonable times and for reasonable periods for inspection by one
representative appointed by (x) the Stockholders holding a Majority of the Registrable Common Shares being registered on behalf of the Initiating Demand Stockholder, in the case of a registration pursuant to Section 3(a), or
(y) Stockholders holding a Majority of the Registrable Common Shares being registered on behalf of all Stockholders, in the case of a registration made pursuant to Section 4(a) by a Person other than an Initiating Demand Stockholder, by
any managing underwriter or underwriters participating in any Underwritten Offering to be effected pursuant to such Registration Statement, and by any attorney, accountant or other agent retained by such Stockholders or any such managing
underwriter, all pertinent financial and other records, pertinent corporate documents and properties of the Company, and cause all of the Company’s officers, directors and employees and the independent registered public accounting firm that has
certified the Company’s financial statements to make themselves available during normal business hours to discuss the business of the Company and to supply all information reasonably requested by any such Stockholders or managing underwriter or
agent thereof in connection with such Registration Statement as shall be necessary to enable such Persons to exercise their due diligence responsibility (subject to the entry by each Person referred to in this Section 8(p) into customary
confidentiality agreements in a form reasonably acceptable to the Company). 
  

 -17- 

 9. Agreements of Stockholders. 
 (a) As a condition to the Company’s obligation under this Agreement to cause Registrable Common Shares of any Stockholder to be included in a
Registration Statement, such Stockholder shall timely provide the Company with all of the information required to be provided in the Registration Statement with respect to such Stockholder pursuant to Items 507 and 508 (or any successor Items) of
Regulation S-K under the Securities Act and such other information as otherwise may reasonably be requested by the Company in connection with the Registration Statement. 
 (b) Each Stockholder shall comply with the prospectus delivery requirements of the Securities Act in connection with the offer and sale of Registrable Common Shares made by such Stockholder pursuant to any
Registration Statement. Upon receipt of any notice from the Company of the occurrence of any event of the kind described in Section 8(e) or Section 8(k), each Stockholder holding Registrable Common Shares shall forthwith discontinue the
disposition of Registrable Common Shares pursuant to the Prospectus or Registration Statement covering such Registrable Common Shares until such Stockholder’s receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 8(e) or the withdrawal of any stop order or other order referred to in Section 8(k), and, if so directed by the Company, shall deliver to the Company all copies, other than permanent file copies then in such Stockholder’s
possession, of the Prospectus covering such Registrable Common Shares at the time of receipt of such notice. 
 (c) To the extent
required by the Securities Act or rules or regulations thereunder, as reasonably determined by the Company, a Stockholder shall consent to disclosure in any Registration Statement to the effect that such Stockholder is or may be deemed to be an
underwriter for purposes of the Securities Act in connection with the offering of Registrable Common Shares of such Stockholder included in such Registration Statement. 
 (d) Each Stockholder shall comply with Regulation M under the Exchange Act in connection with the offer and sale of Registrable Common Shares made by such Stockholder pursuant to any Registration Statement. Each
Stockholder shall provide the Company with such information about such Stockholder’s offer and sale of Registrable Common Shares pursuant to any Registration Statement as the Company shall reasonably request to enable the Company and its
Affiliates to comply with Regulation M under the Exchange Act in connection with any such offer and sale. 
 10. Registration
Expenses. The Company shall pay all Registration Expenses in connection with all registrations pursuant to this Agreement to the extent provided herein. In connection with all such registrations, each Stockholder shall pay all underwriting
discounts and fees, brokerage and sales commissions, and transfer and documentary stamp taxes, if any, relating to the sale or disposition of such Stockholder’s Registrable Common Shares pursuant to the Registration Statement, and, except as
provided in clause (g) of the definition of Registration Expenses, all fees and expenses of counsel to such Stockholder. 
  

 -18- 

 11. Indemnification; Contribution. 
 (a) The Company shall indemnify and hold harmless, to the fullest extent permitted by law, each Stockholder in any offering or sale of Registrable
Common Shares pursuant to this Agreement, each Person, if any, who participates as an underwriter in any such offering and sale of Registrable Common Shares, and each Person, if any, who controls such Stockholder or such underwriter within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and their respective directors, trustees, officers, partners, agents, employees and affiliates against all losses, claims, damages, liabilities and expenses
(including reasonable attorneys’ fees, disbursements and expenses, as incurred, and any amounts paid in any settlement effected with the Company’s consent, which consent shall not be unreasonably withheld or delayed) (collectively,
“Losses”) incurred by such party pursuant to any actual or threatened action, suit, proceeding or investigation arising out of or based upon: (i) any untrue or alleged untrue statement of a material fact contained in, or any
omission or alleged omission of a material fact required to be stated in, the Registration Statement, Prospectus or preliminary Prospectus or any amendment or supplement to any of the foregoing, any Issuer Free Writing Prospectus or any “issuer
information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or necessary to make the statements therein (in the case of a Prospectus, a preliminary Prospectus, an Issuer Free Writing Prospectus or “issuer
information,” in the light of the circumstances then existing) not misleading, except in each case insofar as such statements or omissions arise out of or are based upon (A) any such untrue statement or alleged untrue statement or omission
or alleged omission made in reliance on and in conformity with information with respect to such Stockholder furnished in writing to the Company by such Stockholder or its counsel expressly for use therein, (B) the use of any Prospectus, Issuer
Free Writing Prospectus or “issuer information” after such time as the obligation of the Company to keep effective the Registration Statement of which such Prospectus forms a part has expired or (C) the use of any Prospectus, Issuer
Free Writing Prospectus or “issuer information” after such time as the Company has advised the Stockholders that the filing of an amendment or supplement thereto is required, except such Prospectus, Issuer Free Writing Prospectus or
“issuer information” as so amended or supplemented; or (ii) any violation by the Company of any other federal or state securities laws or regulations applicable to the Company and relating to action required of or inaction by the
Company in connection with any such registration. Notwithstanding the foregoing provisions of this Section 8(a), the Company shall not be liable to any such Stockholder or underwriter or to any other indemnified party under the indemnity
agreement in this Section 8(a) for any Losses that arise out of or are based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Prospectus if either: (i) (A) such Stockholder or
underwriter failed to send or deliver a copy of the Prospectus with or prior to the delivery of written confirmation of the sale of Registrable Common Shares by such Stockholder or underwriter to the Person asserting the claim from which such Losses
arise and (B) the Prospectus would have corrected such untrue statement or alleged untrue statement or such omission or alleged omission; or (ii) (A) such untrue statement or alleged untrue statement or omission or alleged omission is
corrected in an amendment or 

  

 -19- 

 
supplement to the Prospectus and (B) having previously been furnished by or on behalf of the Company with copies of the Prospectus as so amended or
supplemented as required hereunder, such Stockholder or underwriter thereafter fails to deliver such Prospectus, as so amended or supplemented, with or prior to the delivery of written confirmation of the sale of Registrable Common Shares by such
Stockholder or underwriter to the Person asserting the claim from which such Losses arise. Such rights to indemnity and reimbursement of expenses shall survive the transfer of the Registrable Common Shares by such indemnified party. 
 (b) In connection with any Registration Statement filed pursuant to this Agreement, each Stockholder holding Registrable Common Shares to be covered
thereby shall, severally and not jointly with any other Stockholders, indemnify and hold harmless, to the fullest extent permitted by law, the Company, each Person, if any, who participates as an underwriter in any such offering and sale of
Registrable Common Shares and each Person, if any, who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and their respective directors, trustees, officers,
partners, agents, employees and affiliates, against all Losses incurred by such party pursuant to any actual action, suit, proceeding or investigation arising out of or based upon any untrue or alleged untrue statement of a material fact contained
in, or any omission or alleged omission of a material fact required to be stated in, the Registration Statement, Prospectus or preliminary Prospectus or any amendment or supplement to any of the foregoing, any Issuer Free Writing Prospectus or
“issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or necessary to make the statements therein (in case of a Prospectus, preliminary Prospectus or Issuer Free Writing Prospectus, in the
light of the circumstances then existing) not misleading, but only to the extent that any such untrue statement or omission is made in reliance on and in conformity with information with respect to such Stockholder furnished in writing to the
Company by such Stockholder or its counsel specifically for use therein; provided, however, that no Stockholder shall be required to indemnify the Company or any other indemnified party under this Section 11(b) with respect to any amount in
excess of the amount of the total net proceeds received by such Stockholder from sales of the Registrable Common Shares of such Stockholder under such Registration Statement. 
 (c) Any Person entitled to indemnification hereunder agrees to give prompt written notice to the indemnifying party after the receipt by such
indemnified party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which such indemnified party may claim indemnification or contribution pursuant to this Agreement,
provided that failure to give such notification shall not affect the obligations of the indemnifying party pursuant to this Section 11 except to the extent the indemnifying party shall have been actually and materially prejudiced as a result of
such failure. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it
shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the 

  

 -20- 

 
indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation, unless in the reasonable judgment of any indemnified party, based on the opinion of counsel, a conflict of interest is likely to
exist between the indemnifying party and such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall not be liable for the fees and expenses of (i) more than one
counsel for all Stockholders holding Registrable Common Shares who are indemnified parties, selected by the Stockholders holding a Majority of the Registrable Common Shares held by all Stockholders who are indemnified parties (which selection shall
be reasonably satisfactory to the Company), (ii) more than one counsel for the underwriters in an Underwritten Offering or (iii) more than one counsel for the Company, in each case in connection with any one action or separate but similar
or related actions. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party
with respect to such claim, unless in the reasonable judgment of any indemnified party, based on the opinion of counsel, a conflict of interest is likely to exist between an indemnified party and any other of such indemnified parties with respect to
such claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of such additional counsel, provided that the indemnifying party shall not be liable for the fees and expenses of (i) more than one counsel for
all Stockholders holding Registrable Common Shares who are indemnified parties, selected by the Stockholders holding a Majority of the Registrable Common Shares who are indemnified parties (which selection shall be reasonably satisfactory to the
Company), (ii) more than one counsel for the underwriters in an Underwritten Offering or (iii) more than one counsel for the Company, in each case in connection with any one action or separate but similar or related actions. No
indemnifying party, in defense of any such action, suit, proceeding or investigation, shall, except with the consent of each indemnified party, consent to the entry of any judgment or entry into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such action, suit, proceeding or investigation to the extent such liability is covered by the indemnity
obligations set forth in this Section 11. No indemnified party shall consent to entry of any judgment or entry into any settlement without the consent of each indemnifying party. 
 (d) If the indemnification from the indemnifying party provided for in this Section 11 is unavailable to an indemnified party hereunder in
respect of any Losses, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect
the relative fault of the indemnifying party and indemnified party in connection with the actions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that no Stockholder shall be required to
contribute any amount in excess of the amount of the total net proceeds received by such Stockholder from sales of the Registrable Common Shares of the Stockholder under the applicable Registration Statement. The relative fault of such indemnifying
party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue statement or alleged untrue statement of a material 

  

 -21- 

 
fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or
indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses referred to above shall be deemed to
include, subject to the limitations set forth in Section 11(c), any legal or other fees and expenses reasonably incurred by such indemnified party in connection with any investigation or proceeding. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The parties agree that it would not be just and equitable
if contribution pursuant to this Section 11(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the consideration referred to in this Section 11(d). If indemnification is available
under this Section 11, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Section 11(a) or 11(b), as the case may be, without regard to the relative fault of such indemnifying parties or
indemnified party or any other equitable consideration provided for in this Section 11(d). 
 (e) The provisions of this
Section 11 shall be in addition to any liability which any indemnifying party may have to any indemnified party and shall survive the termination of this Agreement. 
 (f) The indemnification and contribution required by this Section 11 shall be made by periodic payments of the amount thereof during the course of any action, suit, proceeding or investigation, as and when
invoices are received or Losses are incurred. 
 12. Participation in Underwritten Offerings. No Stockholder holding Registrable
Common Shares may participate in any Underwritten Offering pursuant to this Agreement unless such Stockholder (i) agrees to sell such Stockholder’s Registrable Common Shares on the basis provided in any underwriting arrangements approved
by the Company, which approval shall not be unreasonably withheld, conditioned or delayed, and (ii) completes and executes all questionnaires, powers of attorney, custody agreements, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements. 
 13. Reports Under the Exchange Act. For so long as any
Registrable Common Shares remain outstanding and the Company is required under the Exchange Act and rules and regulations thereunder to file with the SEC reports pursuant to Section 13 or 15(a) of the Exchange Act, the Company shall use
reasonable best efforts to file such reports with the SEC in a timely manner. 
 14. No Inconsistent Agreements. The Company shall not
after the date of this Agreement enter into any agreement which is inconsistent with the rights granted pursuant to this Agreement to the Stockholders holding Registrable Common Shares. The Stockholders agree for purposes of this Section 14
that a registration rights agreement in customary form relating to a Rule 144A Resale Shelf Registration shall not be deemed inconsistent with the rights of the Stockholders hereunder. 
  

 -22- 

 15. Assignment of Registration Rights. 
 (a) The right to cause the Company to register Registrable Common Shares pursuant to this Agreement may be assigned (but only with all related obligations
hereunder) by any Stockholder holding Registrable Common Shares as of the date of this Agreement only in connection with a transfer of such Registrable Common Shares to a Person that is (i) an Affiliate of such Stockholder, (ii) if such
Stockholder is a natural person, the heir or legal representative of such Stockholder, the executor or administrator of such Stockholder’s estate, or an inter vivos trust for the benefit of such Stockholder or such Stockholder’s
spouse or lineal descendants, or (iii) a partner, member or shareholder of such Stockholder, provided that such transfer is effected in accordance with the terms of the partnership agreement or other organizational document of such Stockholder
and is made for no consideration; provided, that, in each case, as a condition to the effectiveness of any such assignment, such Person shall be required to execute a counterpart of this Agreement. Upon such Person’s execution of such
counterpart, such Person shall be a Stockholder under this Agreement and shall be entitled to the benefits of, and shall be subject to the restrictions contained in, this Agreement, as amended from time to time, that are applicable hereunder to the
Stockholder from whom such rights hereunder were assigned. From and after the date of any such effective assignment, the term “Stockholders” as used herein shall also refer to such Person. 
 (b) In connection with any merger, consolidation, reorganization or similar transaction involving the Company (i) in which the Company is not the
surviving corporation or entity or (ii) which results in the Company becoming the wholly-owned subsidiary of another corporation or other entity, effective provisions shall be made in the instruments pursuant to which such transaction shall be
consummated so that the surviving corporation (in the case of a transaction of the type specified in clause (i)) or the entity which becomes the wholly-owned parent of the Company (in the case of a transaction of the type specified in clause (ii))
shall expressly assume the obligations of the Company hereunder effective upon the consummation of such transaction. In such event, all references herein to the Company shall thereafter be references to the assuming entity and all references to the
Common Stock shall thereafter be references to the class of equity securities (if any) of the assuming entity issued to all holders of the Common Stock as consideration pursuant to such transaction. 
 16. Binding Effect; Benefit. This Agreement shall inure to the benefit of and be binding upon the parties hereto, any Stockholder and any
successor, permitted assign, heir and legal representative thereof; provided, however, that, except as provided in Section 15, this Agreement and the provisions of this Agreement that are for the benefit of the Stockholders shall not be
assignable by any Stockholder, and any such purported assignment shall be null and void. Except to the extent provided in Section 11, nothing in this Agreement, expressed or implied, is intended to confer upon any Person other than the Company,
the Stockholders and their respective successors, permitted assigns, heirs and legal representatives any rights, remedies, obligations or liabilities under or by reason of this Agreement. No purchaser of Registrable Common Shares from a Stockholder
shall be deemed to be a successor or assignee of such Stockholder merely by reason of such purchase. 
  

 -23- 

 17. Amendments and Waivers. 
 (a) The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to
departures from the provisions hereof (each such amendment, modification, supplement, waiver or consent, an “Amendment”) may not be given, unless the Company consents thereto and has obtained the written consent thereto of
Stockholders holding a Majority of the Registrable Common Shares; provided that, if any Amendment would adversely affect any Demand Stockholder, then such Amendment shall also require the written consent of such Demand Stockholder; and provided
further that, if any Amendment would materially and adversely affect any Stockholder other than the Demand Stockholders disproportionately relative to any other Stockholder or Stockholders, then such Amendment shall also require the written consent
of the Stockholders other than the Demand Stockholders holding a Majority of the Registrable Common Shares held by all such Stockholders so disproportionately affected. 
 (b) Notwithstanding the foregoing, an Amendment with respect to a matter that relates exclusively to the rights of Stockholders holding Registrable Common Shares whose securities are being included in a Registration
Statement, but only to the extent that such rights (i) relate exclusively to the distribution of Registrable Common Shares pursuant to such Registration Statement and (ii) do not directly or indirectly affect the rights of other
Stockholders holding Registrable Common Shares, shall be effective if consented to by Stockholders holding at least a Majority of the Registrable Common Shares being included in such Registration Statement; provided that, if any such Amendment would
adversely affect any Stockholder disproportionately relative to any other Stockholder or Stockholders, then such Amendment shall also require the written consent of such Stockholder. 
 (c) Any written consent given by a Demand Stockholder pursuant to Section 17(a) shall only be effective if signed by the Stockholders holding a
Majority of the Registrable Common Shares held by all of the Stockholders that collectively constitute such Demand Stockholder, and any such properly given written consent shall be binding upon each Stockholder holding Registrable Common Shares that
constitutes a part of such Demand Stockholder. Each Stockholder from time to time shall be bound by any Amendment effected pursuant to this Section 17, whether or not any notice, writing or marking indicating such Amendment appears on the
Registrable Common Shares or is delivered to such Stockholder. 
 18. Notices. All notices, demands, requests, consents or other
communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given when (i) delivered personally to the recipient, (ii) sent by confirmed facsimile or
confirmed electronic mail transmission before 5:00 p.m. New York City time on a Business Day, and otherwise on the next Business Day, or (iii) one Business Day after being sent to the recipient by reputable overnight courier service (charges

writing to the Stockholders from time to time, and (ii) if to any Stockholder, to such Stockholder at the address of such Stockholder set forth on the signature pages hereto, or to such other address of any Stockholder as such Stockholder shall
designate in writing to the Company from time to time. 
 19. Interpretation. The headings contained in this Agreement are for
convenience only and shall not affect the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words
“without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this
Agreement. 
 20. Counterparts; Effectiveness. This Agreement may be executed in any number of counterparts, each of which shall be
deemed to be an original and all of which together shall be deemed to be one and the same instrument. This Agreement shall become effective as between the Company and any Stockholder when the Company and such Stockholder shall have received a copy
of counterparts hereof signed by the other. 
 21. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ITS PRINCIPLES OR RULES OF CONFLICT OF LAWS TO THE EXTENT SUCH PRINCIPLES OR RULES WOULD REQUIRE OR PERMIT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. EACH OF THE
PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY CONSENTS TO SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES OF AMERICA LOCATED IN THE COUNTY OF NEW YORK FOR ANY ACTION OR PROCEEDING
ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY (AND AGREES NOT TO COMMENCE ANY ACTION OR PROCEEDING RELATING THERETO EXCEPT IN SUCH COURTS), AND FURTHER AGREES THAT SERVICE OF ANY PROCESS, SUMMONS, NOTICE OR
DOCUMENT BY U.S. REGISTERED MAIL TO ITS RESPECTIVE ADDRESS SET FORTH IN SECTION 18 SHALL BE EFFECTIVE SERVICE OF PROCESS FOR ANY ACTION OR PROCEEDING BROUGHT AGAINST IT IN ANY SUCH COURT. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND
UNCONDITIONALLY WAIVES ANY OBJECTION TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN THE COURTS OF THE STATE OF NEW YORK OR THE UNITED STATES OF AMERICA LOCATED IN THE
COUNTY OF NEW YORK, AND HEREBY FURTHER IRREVOCABLY AND UNCONDITIONALLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

  

 -25- 

 22. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO
TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 23.
Effectiveness; Termination. 
 (a) Notwithstanding any other provision of this Agreement, this Agreement shall become effective at the
Effective Time, provided that, if the Effective Time shall not occur prior to the termination of the Merger Agreement, this Agreement shall not become effective and shall be null and void ab initio. 
 (b) This Agreement shall terminate with respect to any Stockholder (including any Demand Stockholder) on the earlier to occur of (i) the date on
which such Stockholder first ceases to hold any Registrable Common Shares or (ii) the date on which such Stockholder notifies the Company in writing that such Stockholder irrevocably and forever withdraws as a Stockholder under this Agreement.
Notwithstanding any such termination of this Agreement by any Stockholder, all rights, liabilities and obligations of such Stockholder under Sections 10 and 11 shall remain in effect in accordance with their terms. No termination of any
provision of this Agreement shall relieve any party of any liability for any breach of such provision occurring prior to such termination. 
 24. Entire Agreement; Termination of Old PAETEC Agreement and Old US LEC Agreement. 
 (a) This Agreement is intended by the
parties to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and the registration rights granted by the Company with respect to the Registrable Common
Shares. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein, with respect to the registration rights granted by the Company with respect to the Registrable Common Shares. No party hereto
shall have any rights, duties or obligations other than those specifically set forth in this Agreement. This Agreement supersedes all prior agreements and undertakings among the parties with respect to such registration rights. 
 (b) Without limiting the generality of Section 24(a), (i) upon the execution and delivery of this Agreement by Old PAETEC and each Stockholder
set forth on the signature pages hereof that is a party to the Old PAETEC Agreement, the Old PAETEC Agreement shall automatically and with no further action on the part of any Holder thereunder terminate and be of no further force or effect, and
(ii) upon the execution and delivery of this Agreement by US LEC and each Stockholder set forth on the signature pages hereof that is a party to the Old US LEC Agreement, the Old US LEC Agreement shall automatically and with no further action
on the part of any Investor thereunder terminate and be of no further force or effect. 
 25. Specific Performance. Without limiting
the rights of each party hereto to pursue all other legal and equitable rights available to such party for any other parties’ failure 

  

 -26- 

 
to perform their obligations under this Agreement, the parties hereto acknowledge and agree that the remedy at law for any failure to perform their
obligations hereunder would be inadequate and that each of them, respectively, to the extent permitted by applicable law, shall be entitled to specific performance, injunctive relief or other equitable remedies in the event of any such failure,
without bond or other security being required. 
 26. Severability. In the event that any one or more of the provisions contained
herein, or the application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the parties shall negotiate in good faith with a view to the substitution therefor of a suitable and equitable solution
in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid provision, provided, however, that the validity, legality and enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be in any way impaired thereby, it being intended that all of the rights and privileges of the parties hereto shall be enforceable to the fullest extent permitted by law.
