individual Letter of Credit as of any date of determination, the Available Letter of Credit Amount as of such date of determination. 
 (d) The Swing Line Loans. Subject to the terms and conditions of this Agreement, the Swing Line Bank, in its sole discretion, may from time to time on any Business Day after the Agreement Date but
prior to the Maturity Date, make Swing Line Loans to the Borrowers in an amount not to exceed the lessor of (i) Availability, to the extent in effect at such time of determination, as of such Business Day or (ii) $25,000,000. 

  
 50 









 (e) Overadvances. If at any time the amount of the Aggregate Revolving Credit
Obligations exceeds the aggregate Revolving Loan Commitment or any other applicable limitation set forth in this Agreement (including, without limitation, the limitations on Swing Line Loans, Agent Advances and Letters of Credit) such excess (an
“Overadvance”) shall nevertheless constitute a portion of the Obligations that are secured by the Collateral and are entitled to all benefits thereof. In no event, however, shall the Borrowers have any right whatsoever to
(i) receive any Revolving Loan, (ii) receive any Swing Line Loan, or (iii) request the issuance of any Letter of Credit if, before or after giving effect thereto, there shall exist a Default. In the event that (1) the Lenders
shall make any Revolving Loans, (2) the Swing Line Bank shall make any Swing Line Loan, (3) the Revolving Facility Administrative Agent shall make any Agent Advances or (4) the Issuing Bank shall agree to the issuance of any Letter of
Credit, which in any such case gives rise to an Overadvance, the Borrowers shall make, on demand, a payment on the Obligations to be applied to the Revolving Loans, the Swing Line Loans, the Agent Advances and the Letter of Credit Reserve Account,
as appropriate, in an aggregate principal amount equal to such Overadvance. 
 (f) Agent Advances. 

(i) Subject to the limitations set forth below and notwithstanding anything else in this Agreement to the contrary, the
Revolving Facility Administrative Agent is authorized by the Borrowers and the Revolving Facility Lenders, from time to time in the Revolving Facility Administrative Agent’s sole discretion, (A) at any time that a Default exists,
(B) at any time that any of the other conditions precedent set forth in Article 4 have not been satisfied, or (C) at any time an Overadvance exists or would result from any Agent Advance (as defined below), to make Base Rate Loans to
the Borrowers on behalf of the Lenders in an aggregate amount outstanding at any time not to exceed (together with the amount of Swing Line Loans made pursuant to Section 2.1(d) then outstanding) $2,000,000, which the Revolving Facility
Administrative Agent, in its sole discretion, deems necessary or desirable (1) to preserve or protect the Collateral, or any portion thereof, (2) to enhance the likelihood of, or maximize the amount of, repayment of the Loans and other
Obligations, or (3) to pay any other amount chargeable to the Borrowers pursuant to the terms of this Agreement, including costs, fees and expenses as provided under this Agreement (any of such advances are herein referred to as “Agent
Advances”); provided, that the Revolving Facility Majority Lenders may at any time revoke the Revolving Facility Administrative Agent’s authorization to make Agent Advances. Any such revocation must be in writing and shall
become effective prospectively upon the Revolving Facility Administrative Agent’s receipt thereof. The Revolving Facility Administrative Agent shall promptly provide to the Administrative Borrower written notice of any Agent Advance. In no
event shall the Aggregate Revolving Credit Obligations, after giving effect to any Agent Advance, exceed the Revolving Loan Commitment. 
 (ii) The Agent Advances shall be secured by the Collateral and shall constitute Obligations hereunder. Each Agent Advance shall bear interest as a Base Rate Loan. Each Agent Advance shall be subject to
all terms and conditions of this Agreement and the other Loan Documents applicable to Revolving Loans, except that all payments thereon shall be made to the Revolving Facility Administrative Agent solely for its own account and the making of any
Agent Advance shall not require the consent of the Borrowers. The Revolving Facility Administrative Agent shall have no duty or obligation to make any Agent Advance hereunder. 

  
 51 









 (iii) The Revolving Facility Administrative Agent shall notify each Lender
no less frequently than weekly, as determined by the Revolving Facility Administrative Agent, of the principal amount of Agent Advances outstanding as of 12:00 noon (New York, New York time) as of such date, and each Lender’s pro rata share
thereof. Each Lender shall before 2:00 p.m. (New York, New York time) on such Business Day make available to the Revolving Facility Administrative Agent, in immediately available funds, the amount of its pro rata share of such principal amount
of Agent Advances outstanding. Upon such payment by a Lender, such Lender shall be deemed to have made a Base Rate Loan to the Borrowers, notwithstanding any failure of the Borrowers to satisfy the conditions in Section 4.2. The
Revolving Facility Administrative Agent shall use such funds to repay the principal amount of Agent Advances. Additionally, if at any time any Agent Advances are outstanding, any of the events described in Section 9.1(g) or 9.1(h)
shall have occurred, then each Lender shall automatically, upon the occurrence of such event, and without any action on the part of the Revolving Facility Administrative Agent, the Borrowers or the Lenders, be deemed to have purchased an undivided
participation in the principal and interest of all Agent Advances then outstanding in an amount equal to such Lender’s Commitment Ratio and each Lender shall, notwithstanding such Event of Default, immediately pay to the Revolving Facility
Administrative Agent in immediately available funds, the amount of such Lender’s participation (and upon receipt thereof, the Revolving Facility Administrative Agent shall deliver to such Lender, a loan participation certificate dated the date
of receipt of such funds in such amount). The disbursement of funds in connection with the settlement of Agent Advances hereunder shall be subject to the terms and conditions of Section 2.2(e). 

Section 2.2 Manner of Borrowing and Disbursement of Loans. 

(a) Choice of Interest Rate, etc. Any Loan shall, at the option of the Borrowers, be made either as a Base Rate Loan or as a
Eurodollar Loan; provided, however, that (i) if the Administrative Borrower fails to give (x) the Revolving Facility Administrative Agent, in case of Revolving Loans and (y) the Term Facility Administrative Agent, in
case of Term Loans, written notice specifying whether a Eurodollar Loan is to be repaid, continued or converted on a Payment Date, such Loan shall be converted to a Base Rate Loan on the Payment Date in accordance with
Section 2.3(a)(iii), (ii) the Administrative Borrower may not select a Eurodollar Loan (A) on the Agreement Date, (B) with respect to Swing Line Loans, (C) with respect to any Loan, the proceeds of which are to
reimburse the Issuing Bank pursuant to Section 2.15, or (D) if, at the time of such Loan or at the time of the continuation of, or conversion to, a Eurodollar Loan pursuant to Section 2.2(c), a Default exists, and the
applicable Administrative Agent has notified the Administrative Borrower that no Eurodollar Loans may be selected by the Administrative Borrower during the continuance of such Default, and (iii) all Agent Advances shall be made as Base Rate
Loans. Any notice given to any Administrative Agent in connection with a requested Loan hereunder shall be given to the applicable Administrative Agent prior to 11:00 a.m. (New York, New York time) in order for such Business Day to count toward the
minimum number of Business Days required. 

  
 52 









 (b) Base Rate Loans. 

(i) Initial and Subsequent Loans. The Administrative Borrower shall give (x) the Revolving Facility
Administrative Agent, in case of Revolving Loans and (y) the Term Facility Administrative Agent, in case of Term Loans, in the case of Base Rate Loans irrevocable notice by telephone not later than 11:00 a.m. (New York, New York time) one
Business Day prior to the date of such Base Rate Loan and shall immediately confirm any such telephone notice with a written Request for Loan; provided, however, that the failure by the Administrative Borrower to confirm any notice by
telephone with a written Request for Loan shall not invalidate any notice so given. Except as otherwise provided in Section 2.2(f), each Base Rate Loan shall be in a principal amount of no less than $1,000,000 an in an integral multiple
of $100,000 in excess thereof. 
 (ii) Repayments and Conversions. The Borrowers may (A) subject to
Section 2.5, at any time without prior notice repay a Base Rate Loan, or (B) upon at least three (3) Business Days’ irrevocable prior written notice by the Administrative Borrower to (x) the Revolving Facility
Administrative Agent, in case of Revolving Loans and (y) the Term Facility Administrative Agent, in case of Term Loans, in each case, in the form of a Notice of Conversion/Continuation, convert all or a portion of the principal thereof to one
or more Eurodollar Loans; provided, however, that the Borrowers may not elect to convert any Base Rate Loans to Eurodollar Loans during the first thirty (30) days following the Agreement Date (or such earlier date as shall be
specified by the applicable Administrative Agent in its sole discretion by written notice to the Borrowers and the Lenders). Upon the date indicated by the Administrative Borrower, such Base Rate Loan shall be so repaid or converted. 

(c) Eurodollar Loans. 
 (i) Initial and Subsequent Loans. The Administrative Borrower shall give (x) the Revolving Facility Administrative Agent, in case of Revolving Loans and (y) the Term Facility
Administrative Agent, in case of Term Loans, in the case of Eurodollar Loans irrevocable notice by telephone not later than 11:00 a.m. (New York, New York time) three (3) days prior to the date of such Eurodollar Loan and shall immediately
confirm any such telephone notice with a written Request for Loan; provided, however, that the failure by the Administrative Borrower to confirm any notice by telephone with a written Request for Loan shall not invalidate any notice so
given. 
 (ii) Repayments, Continuations and Conversions. At least three (3) Business Days prior
to each Payment Date for a Eurodollar Loan, the Administrative Borrower shall give (x) the Revolving Facility Administrative Agent, in case of Revolving Loans and (y) the Term Facility Administrative Agent, in case of Term Loans, written
notice in the form of a Notice of Conversion/Continuation specifying whether all or a portion of such Eurodollar Loan outstanding on such Payment Date is to be continued in whole or in part as one or more new Eurodollar Loans and also specifying the
new Eurodollar Loan Period applicable to each such new Eurodollar Loan (and subject to the provisions of this Agreement, upon such Payment Date, such Eurodollar Loan shall be so continued). Upon such Payment Date, any Eurodollar Loan (or portion
thereof) not so continued shall be converted to a Base Rate Loan or, subject to Section 2.5, be repaid. 

  
 53 









 (iii) Miscellaneous. Notwithstanding any term or provision of this
Agreement which may be construed to the contrary, each Eurodollar Loan shall be in a principal amount of no less than $5,000,000 and in an integral multiple of $1,000,000 in excess thereof, and at no time shall the aggregate number of all Eurodollar
Loans then outstanding exceed twelve (12). 
 (d) Notification of Lenders. Upon receipt of (i) a Request for Loan or
a telephone, telecopy or deemed request for Loan, (ii) notification from the Issuing Bank that a draw has been made under any Letter of Credit (unless the Issuing Bank will be reimbursed through the funding of a Swing Line Loan), or
(iii) notice from the Administrative Borrower with respect to the prepayment of any outstanding Eurodollar Loan prior to the Payment Date for such Loan, the applicable Administrative Agent shall promptly notify each Lender by telephone or
telecopy of the contents thereof and the amount of each Lender’s portion of any such Loan. Each Lender shall, not later than 1:00 p.m. (New York, New York time) on the date specified for such Loan (under clause (i) or (ii) of this
Section 2.2 (d)) in such notice, make available to the applicable Administrative Agent at the applicable Administrative Agent’s Office, or at such account as such Administrative Agent shall designate, the amount of such
Lender’s portion of the Loan in immediately available funds. 
 (e) Disbursement. Prior to 3:00 p.m. (New York, New
York time) on the date of an Loan hereunder, the applicable Administrative Agent shall, subject to the satisfaction of the conditions set forth in Article 4, disburse the amounts made available to such Administrative Agent by the Lenders in
like funds by (i) transferring the amounts so made available by wire transfer to the Disbursement Account or (ii) in the case of an Loan the proceeds of which are to reimburse the Issuing Bank pursuant to Section 2.15,
transferring such amounts to such Issuing Bank. Unless the applicable Administrative Agent shall have received notice from a Lender prior to 12:00 noon (New York, New York time) on the date of any Loan that such Lender will not make available to
such Administrative Agent such Lender’s ratable portion of such Loan, such Administrative Agent may assume that such Lender has made or will make such portion available to such Administrative Agent on the date of such Loan and such
Administrative Agent may, in its sole discretion and in reliance upon such assumption, make available to the Borrowers or the Issuing Bank, as applicable, on such date a corresponding amount. If and to the extent such Lender shall not have so made
such ratable portion available to the applicable Administrative Agent, such Lender agrees to repay to such Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is
made available to the Borrowers or the Issuing Bank, as applicable, until the date such amount is repaid to such Administrative Agent, (x) for the first two (2) Business Days, at the Federal Funds Rate for such Business Days, and
(y) thereafter, at the Base Rate. If such Lender shall repay to the applicable Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s portion of the applicable Loan for purposes of this
Agreement and if both such Lender and the Borrowers shall pay and repay such corresponding amount, such Administrative Agent shall promptly relend to the Borrowers such corresponding amount. If such Lender does not repay such corresponding amount
immediately upon the applicable Administrative Agent’s demand therefor, such Administrative Agent shall notify the Administrative Borrower and the Borrowers shall immediately pay such corresponding amount to such Administrative Agent. The
failure of any Lender to fund its portion of any Loan shall not relieve any other Lender of its obligation, if any, hereunder to fund its respective portion of the Loan on the date of such borrowing, but no Lender shall be responsible for any such
failure of any other Lender. In the event that a Lender for any reason fails or refuses to fund its portion of an Loan in violation of this Agreement, then, until such time as such Lender has funded its portion of such Loan, or all other Lenders
have received payment in full (whether by repayment or prepayment) of the principal and interest due in respect of such Loan, such non-funding Lender shall not (i) have the right to vote regarding any issue on which voting is required or
advisable under this Agreement or any other Loan Document and, with respect to any such Lender, the amount of the Revolving Loan Commitment or Loans, as applicable, held by such Lender shall not be counted as outstanding for purposes of determining
“Majority Lenders” or “Revolving Majority Lenders” as applicable hereunder, and (ii) be entitled to receive any payments of principal, interest or fees from the Borrowers or the applicable Administrative Agent (or the other
Lenders) in respect of its Loans. 

  
 54 









 (f) Deemed Requests for Loan. Unless payment is otherwise timely made by the
Borrowers, the becoming due of any amount required to be paid under this Agreement or any of the other Loan Documents as principal, interest, reimbursement obligations in connection with Letters of Credit, premiums, fees, reimbursable expenses or
other sums payable hereunder shall be deemed irrevocably to be a Request for Loan on the due date of, and in an aggregate amount required to pay, such principal, interest, reimbursement obligations in connection with Letters of Credit, premiums,
fees, reimbursable expenses or other sums payable hereunder, and the proceeds of a Revolving Loan made pursuant thereto may be disbursed by way of direct payment of the relevant Obligation and shall bear interest as a Base Rate Loan. The Lenders
shall have no obligation to the Borrowers to honor any deemed Request for Loan under this Section 2.2(f) unless all the conditions set forth in Section 4.2 have been satisfied, but, with the consent of the Lenders required
under the last sentence of Section 4.2, may do so in their sole discretion and without regard to the existence of, and without being deemed to have waived, any Default and without regard to the existence or creation of an Overadvance or
the failure by the Borrowers to satisfy any of the conditions set forth in Section 4.2. No further authorization, direction or approval by the Borrowers shall be required to be given by the Borrowers for any deemed Request for Loan under
this Section 2.2(f). 
 (g) Special Provisions Pertaining to Swing Line Loans. 

(i) The Administrative Borrower shall give the Swing Line Bank written notice in the form of a Request for Loan, or notice
by telephone no later than 12:00 noon. (New York, New York time) on the date on which the Borrowers wish to receive any Swing Line Loan followed immediately by a written Request for Loan, with a copy to the Revolving Facility Administrative
Agent; provided, however, that the failure by the Administrative Borrower to confirm any notice by telephone with a written Request for Loan shall not invalidate any notice so given; provided further, however, that any
request by the Administrative Borrower of a Base Rate Loan under the Revolving Loan Commitment shall be deemed to be a request for a Swing Line Loan unless the Administrative Borrower specifically requests otherwise. Each Swing Line Loan shall bear
interest at the rate equal to the Swingline Rate. If the Swing Line Bank, in its sole discretion, elects to make the requested Swing Line Loan, the Swing Line Loan shall be made on the date specified in the notice or the Request for Loan and such
notice or Request for Loan shall specify (i) the amount of the requested Swing Line Loan, and (ii) instructions for the disbursement of the proceeds of the requested Swing Line Loan. Each Swing Line Loan shall be subject to all the terms
and conditions applicable to Revolving Loans, except that all payments thereon shall be payable to the Swing Line Bank solely for its own account. The Swing Line Bank shall have no duty or obligation to make any Swing Line Loans hereunder. The Swing
Line Bank shall not make any Swing Line Loans if the Swing Line Bank has received written notice from any Lender or the Revolving Facility Administrative Agent that one or more applicable conditions precedent set forth in Section 4.2
will not be satisfied (or waived pursuant to the last sentence of Section 4.2) on the requested Loan date. In the event the Swing Line Bank in its sole and absolute discretion elects to make any requested Swing Line Loan, the Swing Line
Bank shall make the proceeds of such Swing Line Loan available to the Borrowers by deposit of Dollars in same day funds by wire transfer to the Disbursement Account. In the event that the Swing Line Bank informs the Revolving Facility Administrative
Agent that it will not make the requested Loan as a Swing Line Loan, then such request will be deemed a request for a Base Rate Loan under the Revolving Loan Commitment. 

  
 55 









 (ii) The Swing Line Bank at any time and from time to time in its sole
discretion but in no event less frequently than once each calendar week, shall notify the Revolving Facility Administrative Agent of the principal amount of Swing Line Loans outstanding as of 3:00 p.m. (New York, New York time) as of such date and
each Lender’s pro rata share (based on its Commitment Ratio) thereof. Each Lender (including the Swing Line Bank) shall before 12:00 noon (New York, New York time) on the next Business Day make available to the Revolving Facility Administrative
Agent, in immediately available funds, the amount of its pro rata share (based on its Commitment Ratio) of such principal amount of Swing Line Loans outstanding. Upon such payment by a Lender, such Lender shall be deemed to have made a Revolving
Loan as a Base Rate Loan to the Borrowers, notwithstanding any failure of the Borrowers to satisfy the conditions in Section 4.2. The Revolving Facility Administrative Agent shall use such funds to repay the principal amount of Swing
Line Loans to the Swing Line Bank together with any interest due and payable on such Swing Line Loans. Additionally, if at any time any Swing Line Loans are outstanding, any of the events described in Section 9.1(g) or 9.1(h)
shall have occurred, then each Lender shall automatically upon the occurrence of such event and without any action on the part of the Swing Line Bank, the Borrowers, the Revolving Facility Administrative Agent or the Lenders be deemed to have
purchased an undivided participation in the principal and interest of all Swing Line Loans then outstanding in an amount equal to such Lender’s Commitment Ratio of the principal and interest of all Swing Line Loans then outstanding and each
Lender shall, notwithstanding such Event of Default, immediately pay to the Revolving Facility Administrative Agent for the account of the Swing Line Bank in immediately available funds, the amount of such Lender’s participation (and upon
receipt thereof, the Swing Line Bank shall deliver to such Lender a loan participation certificate dated the date of receipt of such funds in such amount). The disbursement of funds in connection with the settlement of Swing Line Loans hereunder
shall be subject to the terms and conditions of Section 2.2(e). 

  
 56 









 (h) Each Lender’s obligation to make a Base Rate Loan pursuant to subsection
(c) of this Section 2.2 or to purchase participating interests pursuant to subsection (d) of this Section 2.2 shall be absolute and unconditional and shall not be affected by any circumstance, including, without
limitation, (i) any set-off, counterclaim, recoupment, defense or other right that such Lender or any other Person may have or claim against the Swingline Lender, the Borrowers or any other Person for any reason whatsoever, (ii) the
existence of a Default or an Event of Default or the termination of any Lender’s Revolving Loan Commitment, (iii) the existence (or alleged existence) of any event or condition which has had or could reasonably be expected to have a
Material Adverse Effect, (iv) any breach of this Agreement or any other Loan Document by any Borrower Party, the Administrative Agents or any Lender or (v) any other circumstance, happening or event whatsoever, whether or not similar to
any of the foregoing. If such amount is not in fact made available to the Swing Line Lender by any Lender, the Swing Line Lender shall be entitled to recover such amount on demand from such Lender, together with accrued interest thereon for each day
from the date of demand thereof (x) at the Federal Funds Rate until the second Business Day after such demand and (y) at the Base Rate at all times thereafter. Until such time as such Lender makes its required payment, the Swing Line
Lender shall be deemed to continue to have outstanding Swingline Loans in the amount of the unpaid participation for all purposes of the Loan Documents. In addition, such Lender shall be deemed to have assigned any and all payments made of principal
and interest on its Loans and any other amounts due to it hereunder to the Swing Line Lender to fund the amount of such Lender’s participation interest in such Swing Line Loans that such Lender failed to fund pursuant to this Section, until
such amount has been purchased in full. 
 (i) Funding of Term Loans into Escrow. If the AboveNet Acquisition has not
occurred on or prior to July 2, 2012, each Term Facility Lender severally (and not jointly) shall, on July 3, 2012, make a single Term Loan in a principal amount equal to such Term Facility Lender’s Commitment, the gross proceeds of
such Term Loans, net upfront fees, shall be deposited into an escrow account pursuant to an Escrow Agreement and such Escrow Proceeds shall not be disbursed other than pursuant to the terms of such Escrow Agreement (which shall include, in any
event, without limitation, the prepayment of Term Loans with all amounts in such Escrow Account in the event the AboveNet Acquisition shall not have been consummated on or prior to December 18, 2012).

prior calendar quarter, commencing on September 30, 2012 in the case of Base Rate Loans and shall be payable monthly in arrears on the last day of each calendar month for the prior calendar month commencing July 30, 2012 in the case of
Swing Line Loans. Interest on Base Rate Loans and Swing Line Loans then outstanding shall also be due and payable on the Maturity Date (or the date of any earlier prepayment in full of the Obligations). Interest shall accrue and be payable on each
Base Rate Loan at the simple per annum interest rate equal to the sum of (A) the Base Rate and (B) the Applicable Margin. Interest shall accrue and be payable on each Swing Line Loan at the simple per annum interest rate equal to the

 57 









 (ii) On Eurodollar Loans. Interest on each Eurodollar Loan shall be
computed for the actual number of days elapsed on the basis of a hypothetical year of three hundred sixty (360) days and shall be payable in arrears on (x) the Payment Date for such Loan, and (y) if the Eurodollar Loan Period for such
Loan is greater than three (3) months, on the last day of such three (3) month period and on the last day of the applicable Eurodollar Loan Period for such Loan. Interest on Eurodollar Loans then outstanding shall also be due and payable
on the Maturity Date (or the date of any earlier prepayment in full of the Obligations). Interest shall accrue and be payable on each Eurodollar Loan at a rate per annum equal to the sum of (A) the Eurodollar Basis applicable to such Eurodollar

 (iii) If No Notice of Selection of Interest Rate. If the
Administrative Borrower fails to give the applicable Administrative Agent timely notice of its selection of a Eurodollar Basis, or if for any reason a determination of a Eurodollar Basis for any Loan is not timely concluded, the Base Rate shall
apply to such Loan. If the Administrative Borrower fails to elect to continue any Eurodollar Loan then outstanding prior to the last Payment Date applicable thereto in accordance with the provisions of Section 2.2, as applicable, the
Base Rate shall apply to such Loan commencing on and after such Payment Date. 
 (b) Upon Default. If all or a portion of
(i) the principal amount of any Loan or (ii) any interest payable thereon shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum which is the
rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section 2.3 plus 2.00% per annum from the date of such non-payment until the earliest to occur of (i) waiver of the applicable Event
of Default in accordance with Section 11.12, (ii) agreement by the Majority Lenders to rescind the charging of interest at the Default Rate, or (iii) payment in full of the Obligations. The Lenders shall not be required to

(a) Fee Letter. Each Borrower agrees, jointly and severally, to pay to the applicable Administrative Agent such fees as are set
forth in the Fee Letter. 
 (b) Unused Line Fee. Each Borrower agrees, jointly and severally, to pay to the Revolving
Facility Administrative Agent, for the account of the Revolving Facility Lenders in accordance with their respective Commitment Ratios, an unused line fee (“Unused Line Fee”) on the aggregate amount by which the Revolving Loan
Commitment exceeded the sum of the average daily amount of Aggregate Revolving Credit Obligations (other than with respect to any Swing Line Loans and Agent Advances) for each day from the Agreement Date through the Maturity Date (or the date of any
earlier prepayment in full of the Obligations), at a per annum rate equal to the Unused Line Fee Rate. Such Unused Line Fee shall be computed on the basis of a hypothetical year of three hundred sixty five (365)/three hundred sixty six
(366) days for the actual number of days elapsed, shall be payable in arrears on September 30, 2012, and shall be payable quarterly in arrears on the last day of each calendar quarter thereafter for the immediately preceding calendar

 (i) The Borrowers shall pay to the Revolving Loan Administrative Agent for the account of the Lenders, in accordance with their respective Commitment Ratios, a fee on the undrawn amount of each
outstanding Letter of Credit for each day such Letter of Credit is outstanding from the Date of Issue through the Maturity Date (or the date of any earlier prepayment in full of the Obligations) at a rate per annum on such amount equal to the
Applicable Margin with respect to Eurodollar Loans in effect from time to time. Such Letter of Credit fee shall be computed on the basis of a hypothetical year of three hundred sixty (360) days for the actual number of days elapsed, shall be
payable quarterly in arrears for each calendar quarter on the last day of the immediately preceding calendar quarter, commencing on September 30, 2012, and if then unpaid, on the Maturity Date (or the date of any earlier prepayment in full of

(360) days for the actual number of days elapsed, shall be payable quarterly in arrears on the last day of each calendar quarter for the immediately preceding calendar quarter, commencing on September 30, 2012 and, if then unpaid on the

Section 2.4, the first day of the applicable period shall be included and the date of the payment shall be excluded. 
 Section 2.5 Prepayments/Reduction of Commitments. 
 (a) Voluntary
Prepayments. The principal amount of any Base Rate Loan may be prepaid in full or in part at any time, upon delivery of a Notice of Prepayment to the applicable Administrative Agent not later than 11:00 a.m. (New York, New York time) one
(1) Business Days prior to such prepayment. The principal amount of any Eurodollar Loan may be prepaid prior to the applicable Payment Date, upon delivery of a Notice of Prepayment to the applicable Administrative Agent not later than 11:00
a.m. (New York, New York time) three (3) Business Days prior to such prepayment. Each Notice of Prepayment of any Eurodollar Loan shall be irrevocable. Upon receipt of any Notice of Prepayment or notice of repayment, the applicable
Administrative Agent shall promptly notify each applicable Lender of the contents thereof by telephone or telecopy and of such Lender’s portion of the repayment or prepayment. Prepayments of principal under this Section 2.5(a) shall
be in minimum amounts of, with respect to Base Rate Loans, $1,000,000 and integral multiples of $100,000 in excess thereof, and, with respect to Eurodollar Loans, $5,000,000, and integral multiples of $1,000,000 in excess thereof, or, if less, the
entire outstanding amount of such Loan. Upon the occurrence of a Repricing Event occurring on or prior to the date that is one year from the Agreement Date, the Borrowers shall pay to the Term Facility Administrative Agent for the benefit of the
affected Lenders an amount equal to 1.0% of the aggregate principal amount of Loans so prepaid or refinanced. Any prepayment of Loans shall not affect the Borrowers’ obligation to continue to make payments under any swap agreement (as defined
in 11 U.S.C. §101), including, without limitation, any such swap agreement that is a Lender Hedge Agreement, which shall remain in full force and effect notwithstanding such prepayment, subject to the terms of the applicable swap agreement. All
prepayments of Loans pursuant to this Section 2.5(a) shall be applied to the remaining amortization payments under the Term Loan Facility as directed by the Borrower. Notwithstanding the foregoing, the Borrowers shall not make any
repayment or prepayment of the Revolving Loans unless and until the balance of the Swing Line Loans and the Agent Advances then outstanding is zero. Except as provided in Section 2.5(b), any repayment and prepayment of Loans outstanding
under the Revolving Loan Commitment shall not reduce the Revolving Loan Commitment. 
 (b) Mandatory Prepayment.

 (i) Within five (5) Business Days after financial statements have been delivered pursuant to Section 7.2
and the related Compliance Certificate has been delivered pursuant to Section 7.3(a) (the date of such prepayment, the “ECF Payment Date”), the Borrowers shall cause to be prepaid an aggregate principal amount of Term
Loans equal to (A) 50% (such percentage as it may be reduced as described below, the “ECF Percentage”) of their Excess Cash Flow, if any, for the fiscal year covered by such financial statements (commencing with the first full
fiscal year ending after the Agreement Date) minus (B) at the Borrower’s option, the sum of all prepayments of Term Loans made under Section 2.5(a) during such fiscal year and after the end of such fiscal year and prior to the
ECF Payment Date to the extent (1) such amounts were not deducted from a previous mandatory prepayment under this Section 2.5(b)(i) in respect of a prior period and (2) such prepayments are not funded with the proceeds of long
term Funded Debt; provided that (x) the ECF Percentage shall be 25% if the Total Leverage Ratio at the end of the fiscal year covered by such financial statements is not greater than 3.5:1.0 and not less than or equal to 2.5:1.0 and
(y) the ECF Percentage shall be 0% if the Total Leverage Ratio at the end of the fiscal year covered by such financial statements is not greater than 2.5:1.0.

 (ii) (A) Subject to Section 2.5(b)(ii)(B), upon receipt by the Borrowers or any
of their Restricted Subsidiaries of any Net Cash Proceeds from Asset Sales in an aggregate amount, at any one time and in respect of an individual Asset Sale or several Asset Sales, equal to or greater than $50,000,000, the Borrowers shall make a
prepayment, in accordance with Section 2.5(b)(ii)(C), of an aggregate principal amount of Term Loans equal to the product of the aggregate amount of any such Net Cash Proceeds from Asset Sales realized or received multiplied by the Asset
Fraction; provided that no such prepayment shall be required pursuant to this Section 2.5(b)(ii)(A) with respect to such portion of such Net Cash Proceeds from Asset Sales that the Administrative Borrower shall have, on or prior
to such date, given written notice to the Term Facility Administrative Agent of its intent to reinvest in accordance with Section 2.5(b)(ii)(B) (which notice may only be provided if no Event of Default has occurred and is then
continuing); 
 (B) Any Net Cash Proceeds from Asset Sales received by a Borrower from any Asset Sale may, at the
Borrowers’ option, be reinvested within 360 days in Replacement Assets; provided, that (x) such newly acquired assets shall be subject to the Security Documents and Sections 5.1(w) and 6.16 and (y) the purchase of
the Replacement Assets is consummated no later than (1) the 360th day after such Asset Sale or (2) so long as a binding agreement with respect to the purchase of Replacement Assets is entered into within 360 days after the Asset Sale, 90
days after the date of such binding agreement; provided, however, that any Net Cash Proceeds from Asset Sales not applied (or, in the case of the foregoing clause (B)(y)(2), committed to be applied) during the 360 day period provided
for in this subsection (B) shall, immediately upon expiration of such 360 day period, constitute Net Cash Proceeds from Asset Sales which are required to be used to prepay Term Loans in accordance with the foregoing subsection (A) and are
not permitted to be retained pursuant to this subsection (B); 
 (C) On each occasion that the Borrowers must make a prepayment
of the Term Loans pursuant to this Section 2.5(b)(ii), the Borrowers shall, within three (3) Business Days after the date of realization or receipt of such Net Cash Proceeds from Asset Sales (or, in the case of prepayments required
pursuant to the proviso to Section 2.5(b)(ii)(B), within three (3) Business Days of the deadline specified in such proviso or of the date the Borrowers reasonably determine that such Net Cash Proceeds from Asset Sales are no longer
intended to be or cannot be so reinvested, as the case may be), make a prepayment of the principal amount of Term Loans in an amount equal to the product of any such Net Cash Proceeds from Asset Sales realized or received multiplied by the Asset
Fraction. 

  
 61 









 (iii) If a Borrower or any Restricted Subsidiary incurs or issues any Funded Debt not
expressly permitted to be incurred or issued pursuant to Section 8.1, the Borrowers shall cause to be prepaid an aggregate principal amount of Term Loans equal to 100% of all Net Cash Proceeds from Indebtedness received therefrom on or
prior to the date which is three (3) Business Days after the receipt of such Net Cash Proceeds from Indebtedness. 
 (iv)
In the event that the AboveNet Acquisition does not occur on or prior to December 18, 2012, the Borrowers shall cause, within three Business Days after such date, to be prepaid an aggregate principal amount of the outstanding Loans equal to
100% of the Escrow Proceeds. 
 (v) Each prepayment of Term Loans pursuant to this Section 2.5(b) shall be applied
first, with respect to the Term Loans ratably based on the then aggregate outstanding principal amounts thereof and to the installments thereof pro rata in direct order of maturity for the twenty four (24) months immediately following
the applicable prepayment event and second, to the remaining installments thereof pro rata. 
 (c) Interest and
Funding Losses. All prepayments of Loans under this Section 2.5 shall be accompanied by all accrued interest thereon together with, in the case of any such prepayment of a Eurodollar Loan on a date other than the last day of an
Interest Period therefor, any Funding Loss or reasonable out-of-pocket expenses incurred by the Lenders or applicable Administrative Agent in connection with such prepayment, as set forth in Section 2.9. Each prepayment of Loans under
this Section 2.5 shall be paid to the Lenders in accordance with their respective Commitment Ratios. 
 (d)
Reduction of Commitments. The Borrowers shall have the right, at any time and from time to time after the Agreement Date and prior to the Maturity Date, upon at least ten (10) Business Days’ prior written notice (which such notice
may be be conditioned upon the effectiveness of other credit facilities or another event) to the Revolving Facility Administrative Agent, without premium or penalty, to cancel or reduce permanently all or a portion of the Revolving Loan Commitment
on a pro rata basis among the Lenders in accordance with their respective Commitment Ratios; provided, that (i) any such partial reduction be made in an amount not less than $1,000,000 and in integral multiples of $1,000,000 in excess
thereof and (ii) the Revolving Loan Commitment may not be reduced to an amount below the then outstanding Letter of Credit Obligations unless in compliance with subsection (iii) below. As of the date of cancellation or reduction set
forth in such notice, the Revolving Loan Commitment shall be permanently canceled or reduced to the amount stated in the Administrative Borrower’s notice for all purposes herein, and the Borrowers shall (i) pay to the Revolving Facility
Administrative Agent for the account of the Lenders the amount necessary to repay in full the principal amount of the Agent Advances, Swing Line Loans and Revolving Loans or reduce the principal amount of the Agent Advances, Swing Line Loans and
Revolving Loans then outstanding to not more than the amount of the Revolving Loan Commitment as so reduced, together with accrued unpaid interest on the amount so prepaid and the Unused Line Fee accrued through the date of the reduction with
respect to the amount reduced, and (ii) reimburse the Revolving Facility Administrative Agent and the Lenders for any Funding Loss or reasonable out-of-pocket expense incurred by any of them in connection with such payment as set forth in
Section 2.9 and (iii) in the case of cancellation of the Revolving Loan Commitment, shall secure the Letter of Credit Obligations through the delivery of cash collateral to the Issuing Bank in an amount equal to one hundred five
percent (105%) of the Letters of Credit Obligations. 

  
 62 









 (d) Commitment Termination. The Term Loan Commitment of each Term Facility Lender
shall be automatically and permanently reduced to $0 upon the making of Term Loans by such Term Facility Lender pursuant to Section 2.1(a). 
 Section 2.6 Repayment. 
 (a) The Revolving Loans. All unpaid
principal and accrued interest on the Agent Advances, Swing Line Loans and Revolving Loans shall be due and payable in full on the Maturity Date. Notwithstanding the foregoing, however, in the event that at any time and for any reason there shall
exist an Overadvance, the Borrowers shall pay to the Revolving Facility Administrative Agent, on demand/in accordance with Section 2.1(e), an amount equal to the Overadvance, which payment shall constitute a mandatory payment of the
Revolving Loans, Agent Advances, Swing Line Loans and Letter of Credit Reserve Account, as appropriate. 
 (b) The Loans.
The Borrowers shall repay to the Term Facility Administrative Agent for the ratable account of the Term Facility Lenders (i) on the last Business Day of each March, June, September and December commencing the last Business Day of September
2012, an annual aggregate principal amount equal to 1.00% of the aggregate principal amount of all Term Loans outstanding on the Agreement Date (which payments shall be reduced as a result of the application of prepayments in accordance with
Section 2.5(a) and Section 2.5(b)(iv), in each case, solely to the extent of any such amounts applied to the prepayment of the Term Loans) and (ii) on the Maturity Date, the aggregate principal amount of all Term Loans
outstanding on such date. 
 (c) The Other Obligations. In addition to the foregoing, the Borrowers hereby promise,
jointly and severally, to pay all Obligations (other than Obligations in respect of Bank Products), including, without limitation, the principal amount of the Loans, amounts drawn under Letters of Credit and interest and fees on the foregoing, as
the same become due and payable hereunder and, in any event, on the Maturity Date. 
 Section 2.7 Notes; Loan
Accounts. 
 (a) The Loans shall be repayable in accordance with the terms and provisions set forth herein and, upon request
by any Lender, the Loans owed to such Lender shall be evidenced by Notes. A Note shall be payable to the order of each Lender requesting such a Note in accordance with the Commitment Ratio of such Lender. Each such Note shall be issued by the
Borrowers to the applicable Lender and shall be duly executed and delivered by an Authorized Signatory of each Borrower. 
 (b)
The applicable Administrative Agent shall open and maintain on its books in the name of the Borrowers a loan account with respect to the Loans and interest thereon (the “Loan Account”). The applicable Administrative Agent shall
debit such Loan Account for the principal amount of each Loan made by it on behalf of the Lenders, accrued interest thereon, and all other amounts which shall become due from the Borrowers pursuant to this Agreement and shall credit the Loan Account
for each payment which the Borrowers shall make in respect to the Obligations. The records of the applicable Administrative Agent with respect to such Loan Account shall be conclusive evidence of the Loans and accrued interest thereon, absent
manifest error. 

  
 63 









 Section 2.8 Manner of Payment. 

(a) When Payments Due. 
 (i) Each payment (including any prepayment) by the Borrowers on account of the principal of or interest on the Loans, fees, and any other amount owed to any member of the Lender Group under this Agreement
or the other Loan Documents shall be made not later than 1:00 p.m. (New York, New York time) on the date specified for payment under this Agreement or any other Loan Document to the applicable Administrative Agent at such Administrative Agent’s
Office, for the account of the Lenders, the Issuing Bank or the applicable Administrative Agent, as the case may be, in Dollars in immediately available funds. Any payment received by an Administrative Agent after 1:00 p.m. (New York, New York
time) shall be deemed received on the next Business Day. In the case of a payment for the account of a Lender, the applicable Administrative Agent will promptly thereafter distribute the amount so received in like funds to such Lender. In the case
of a payment for the account of the Issuing Bank, the Revolving Facility Administrative Agent will promptly thereafter distribute the amount so received in like funds to the Issuing Bank. If the applicable Administrative Agent shall not have
received any payment from the Borrowers as and when due, such Administrative Agent will promptly notify the Lenders accordingly. 
 (ii) Except as provided in the definition of Eurodollar Loan Period, if any payment under this Agreement or any other Loan Document shall be specified to be made on a day which is not a Business Day, it
shall be made on the next succeeding day which is a Business Day, and such extension of time shall in such case be included in computing interest and fees, if any, in connection with such payment. 

(b) No Deduction. 
 (i) Any and all payments of principal and interest, or of any fees or indemnity or expense reimbursements by the Borrowers hereunder or under any other Loan Documents (the “Borrower
Payments”) shall be made without setoff or counterclaim and free and clear of and without deduction for any and all current or future taxes, levies, imposts, deductions, charges or withholdings with respect to the Borrower Payments and all
interest, penalties or similar liabilities with respect thereto, excluding taxes imposed on the net income of any member of the Lender Group by the jurisdiction under the laws of which such member of the Lender Group is organized or conducts
business or any political subdivision thereof (all such nonexcluded taxes, levies, imposts, deductions, charges or withholdings and liabilities collectively or individually “Taxes”). If any Borrower shall be required to deduct any
Taxes from or in respect of any sum payable to any member of the Lender Group hereunder or under any other Loan Document, (i) the sum payable shall be increased by the amount (an “additional amount”) necessary so that after
making all required deductions (including deductions applicable to additional sums payable under this Section 2.8(b)(i)) such member of the Lender Group shall receive an amount equal to the sum it would have received had no such
deductions been made, (ii) such Borrower shall make such deductions, and (iii) such Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with Applicable Law. If a payment made to a Lender under
any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code,
as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by
applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative
Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Each Lender agrees that if any
form or certification it previously delivered pursuant to the immediately preceding sentence expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative
Agent in writing of its legal inability to do so. 

  
 64 









 (ii) In addition, the Borrowers shall pay to the relevant Governmental
Authority in accordance with Applicable Law any current or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery or registration
of, or otherwise with respect to, this Agreement or any other Loan Document (such taxes being “Other Taxes”). 
 (iii) The Borrowers shall indemnify the members of the Lender Group for the full amount of Taxes and Other Taxes with respect to Borrower Payments paid by such Person, and any liability (including
penalties, interest and expenses (including reasonable attorney’s fees and expenses)) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted by the relevant Governmental Authority.
A certificate setting forth and containing an explanation in reasonable detail of the manner in which such amount shall have been determined and the amount of such payment or liability prepared by a member of the Lender Group or the applicable
Administrative Agent on its behalf, absent manifest error, shall be final, conclusive and binding for all purposes. Such indemnification shall be made within thirty (30) days after the date the applicable Administrative Agent or such member, as
the case may be, makes written demand therefor. If any Taxes or Other Taxes for which the applicable Administrative Agent or any member of the Lender Group has received indemnification from the Borrowers hereunder shall be finally determined to have
been incorrectly or illegally asserted and are refunded to such Administrative Agent or such member, such Administrative Agent or such member, as the case may be, shall promptly forward to the Borrowers any such refunded amount (after deduction of
any Tax or Other Tax paid or payable by any member of the Lender Group as a result of such refund), not exceeding the increased amount paid by the Borrowers pursuant to this Section 2.8(b). 

  
 65 









 (iv) As soon as practicable after the date of any payment of Taxes or Other
Taxes by the Borrowers to the relevant Governmental Authority, the Administrative Borrower will deliver to each Administrative Agent, at its address, the original or a certified copy of a receipt issued by such Governmental Authority evidencing
payment thereof. 
 (v) On or prior to the Agreement Date (or, in the case of any Lender that becomes a party to
this Agreement pursuant to an Assignment and Acceptance, on or prior to the effective date of such Assignment and Acceptance), each Lender which is organized in a jurisdiction other than the United States or a political subdivision thereof (a
“Foreign Lender”) shall provide each of the Administrative Agents and the Administrative Borrower with either (A) two (2) properly executed originals of Form W-8ECI or Form W-8BEN (or any successor forms) prescribed by the
Internal Revenue Service or other documents satisfactory to the Administrative Borrower and the Administrative Agents, as the case may be, certifying (1) as to such Foreign Lender’s status for purposes of determining exemption from United
States withholding taxes with respect to all payments to be made to such Foreign Lender hereunder and under any other Loan Documents or Bank Products Documents or (2) that all payments to be made to such Foreign Lender hereunder and under any
other Loan Documents and Bank Products Documents are subject to such taxes at a rate reduced to zero by an applicable tax treaty, or (B)(1) a certificate executed by such Lender certifying that such Lender is not a “bank” and that
such Lender qualifies for the portfolio interest exemption under Section 881(c) of the Code, and (2) two (2) properly executed originals of Internal Revenue Service Form W-8BEN (or any successor form), in each case, certifying such
Lender’s entitlement to an exemption from United States withholding tax with respect to payments of interest to be made hereunder or under any other Loan Documents or Bank Products Documents. Each such Foreign Lender agrees to provide the
Administrative Agents and the Administrative Borrower with new forms prescribed by the Internal Revenue Service upon the expiration or obsolescence of any previously delivered form, or after the occurrence of any event requiring a change in the most
recent forms delivered by it to the Administrative Agents and the Administrative Borrower. 
 (vi) The Borrowers
shall not be required to indemnify any Foreign Lender, or to pay any additional amounts to such Foreign Lender pursuant to Section 2.8(b)(i) or 2.8(b)(iii) to the extent that (A) the obligation to withhold amounts with
respect to United States Federal, state or local withholding tax existed on the date such Foreign Lender became a party to this Agreement (or, in the case of a transferee, on the effective date of the Assignment and Acceptance pursuant to which such
transferee became a Lender) or, with respect to payments to a new lending office, the date such Foreign Lender designated such new lending office; provided, however, that this clause (A) shall not apply to any Foreign Lender that
became a Lender or new lending office that became a new lending office as a result of an assignment or designation made at the request of the Administrative Borrower; and provided further, however, that this clause (A) shall not
apply to the extent the indemnity payment or additional amounts, if any, that any member of the Lender Group through a new lending office would be entitled to receive (without regard to this clause (A)) do not exceed the indemnity payment or
additional amounts that the Person making the assignment or transfer to such member of the Lender Group making the designation of such new lending office would have been entitled to receive in the absence of such assignment, transfer or designation
or (B) the obligation to pay such additional amounts or such indemnity payments would not have arisen but for a failure by such member of the Lender Group to comply with the provisions of Section 2.8(b)(v). 

  
 66 









 (vii) Nothing contained in this Section 2.8(b) shall require any
member of the Lender Group to make available to the Borrowers any of its tax returns (or any other information) that it deems confidential or proprietary. 
 Section 2.9 Reimbursement. Whenever any Lender shall sustain or incur any Funding Losses (including losses of anticipated profits) or reasonable out-of-pocket expenses in connection with
(a) failure by the Borrowers to borrow or continue any Eurodollar Loan, or convert any Loan to a Eurodollar Loan, in each case, after having given notice of their intention to do so in accordance with Section 2.2 (whether by reason
of the election of the Borrowers not to proceed or the non-fulfillment of any of the conditions set forth in this Agreement), or (b) prepayment of any Eurodollar Loan in whole or in part for any reason or (c) failure by the Borrowers to
prepay any Eurodollar Loan after giving notice of its intention to prepay such Loan, each Borrower agrees, jointly and severally, to pay to such Lender, promptly upon such Lender’s demand therefor, an amount sufficient to compensate such Lender
for all such Funding Losses and reasonable out-of-pocket expenses. Such Lender’s good faith determination of the amount of such Funding Losses and reasonable out-of-pocket expenses, absent manifest error, shall be binding and conclusive. Losses
subject to reimbursement hereunder shall include, without limitation, expenses incurred by any Lender or any participant of such Lender permitted hereunder in connection with the re-employment of funds prepaid, repaid, not borrowed, or paid, as the
case may be, and any lost profit of such Lender or any participant of such Lender over the remainder of the Eurodollar Loan Period for such prepaid Loan. For purposes of calculating amounts payable to a Lender under this paragraph, each Lender shall
be deemed to have actually funded its relevant Eurodollar Loan through the purchase of a deposit bearing interest at the Eurodollar Rate in an amount equal to the amount of that Eurodollar Loan and having a maturity and repricing characteristics
comparable to the relevant Eurodollar Loan Period; provided, however, that each Lender may fund each of its Eurodollar Loans in any manner it sees fit, and the foregoing assumption shall be utilized only for the calculation of amounts
payable under this Section. 
 Section 2.10 Pro Rata Treatment. 

(a) Loans. Each Loan with respect to the Loans from the Lenders under this Agreement shall be made pro rata on the basis of their
respective Commitment Ratios. 

  
 67 









 (b) Payments. Each payment and prepayment of the principal of the Loans and each
payment of interest on the Loans received from the Borrowers shall be made by the applicable Administrative Agent to the applicable Lenders pro rata on the basis of their respective unpaid principal amounts thereof outstanding immediately prior to
such payment or prepayment (except in cases when a Lender’s right to receive payments is restricted pursuant to Section 2.2(e)). If any Lender shall obtain any payment (whether involuntary, through the exercise of any right of
set-off or otherwise) on account of the Loans in excess of its ratable share of Loans under its Commitment Ratio (or in violation of any restriction set forth in Section 2.2(e)), such Lender shall forthwith purchase from the other
Lenders such participation in the Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery without interest thereon unless the Lender
obligated to repay such amount is required to pay interest. Each Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.10(b) may, to the fullest extent permitted by law, exercise all
its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrowers in the amount of such participation. This Section 2.10(b) shall not apply to
any payments made on account of, or in connection with, an assignment of, or the sale of a participation in, any rights and obligations hereunder, in each case, in accordance with the provisions of Section 11.5, as such section may be
amended from time to time. 
 Section 2.11 Application of Payments. 

(a) Payments Prior to Event of Default. At all times during which an Event of Default has not occurred and is continuing, all
amounts received by any Administrative Agent from the Borrowers, shall be distributed by such Administrative Agent in the following order of priority: 
 FIRST, pro rata, to the payment of (i) out-of-pocket costs and expenses (including reasonable attorneys’ fees) of each Administrative Agent and the Collateral Agent incurred by such
Administrative Agent and the Collateral Agent in connection with the enforcement of the rights of the Lender Group under the Loan Documents pursuant to either Facility and (ii) any Agent Advances made by the Revolving Facility Administrative
Agent under or pursuant to the terms of the Loan Documents and interest accrued thereon; 
 SECOND, pro rata, to the payment of
any fees and reimbursable expenses then due and payable to each Administrative Agent, the Issuing Bank or the Swing Line Bank hereunder or under any other Loan Documents; 
 THIRD, pro rata, to the payment of all Obligations consisting of accrued fees and interest then due and payable to the Lenders hereunder; 

FOURTH, to the payment of principal then due and payable on the Loans and unreimbursed Letter of Credit Obligations (or cash collateral
up to 105% of outstanding exposure) on a pro rata basis; 
 FIFTH, to the payment of the Obligations arising in respect of Bank
Products then due and payable on a pro rata basis; 

  
 68 









 SIXTH, to the payment of all other Obligations not otherwise referred to in this
Section 2.11(a) then due and payable; and 
 SEVENTH, upon satisfaction in full of all Obligations, to the Borrowers
or as otherwise required by law. 
 (b) Payments Subsequent to Event of Default. Notwithstanding anything in this
Agreement or any other Loan Document which may be construed to the contrary, subsequent to the occurrence and during the continuance of an Event of Default, payments and prepayments with respect to the Obligations made to the Lender Group, or any of
them, or otherwise received by any member of the Lender Group (from realization on Collateral or otherwise) shall be distributed in the following order of priority (subject, as applicable, to Section 2.10 and to the terms and provisions
of the Intercreditor Agreement): 
 FIRST, pro rata, to the payment of (i) out-of-pocket costs and expenses (including
reasonable attorneys’ fees) of each Administrative Agent and the Collateral Agent incurred in connection with the enforcement of the rights of the Lender Group under the Loan Documents, and (ii) any Agent Advances made by the Revolving
Facility Administrative Agent under or pursuant to the terms of the Loan Documents (including any costs incurred in connection with the sale or disposition of any Collateral); 
 SECOND, pro rata, to payment of any fees owed to each Administrative Agent, the Issuing Bank or the Swing Line Bank hereunder or under any other Loan Document; 

THIRD, to the payment of out-of-pocket costs and expenses (including reasonable attorneys’ fees) of the Lenders incurred in
connection with the enforcement of their respective rights under the Loan Documents; 
 FOURTH, to the payment of all
Obligations consisting of accrued fees and interest payable to the Lenders hereunder; 
 FIFTH, pro rata, to (i) the payment
of principal on the Loans then outstanding, (ii) the Letter of Credit Reserve Account to the extent of one hundred five percent (105%) of any Letter of Credit Obligations then outstanding; 

SIXTH, and (iii) to the payment of any Obligation arising in respect of the Bank Products; 

SEVENTH, to any other Obligations not otherwise referred to in this Section 2.11(b); and 

EIGHTH, upon satisfaction in full of all Obligations, to the Borrowers or as otherwise required by law. 

Section 2.12 Use of Proceeds. The proceeds of the Loans shall be used by the Borrowers to consummate the Refinancing, to fund
the Transactions, to fund future acquisitions permitted hereunder, to support strategic growth initiatives, to provide for ongoing working capital and for the Borrowers’ and their Subsidiaries’ general corporate purposes and pay the fees
and expenses incurred in connection with the AboveNet Acquisition, the Refinancing and the Transactions. 

  
 69 









 Section 2.13 All Obligations to Constitute One Obligation. All Obligations shall
constitute one general obligation of the Borrowers and shall be secured by the Collateral Agent’s security interest (on behalf of, and for the benefit of, the Lender Group) and Lien upon all of the Collateral, and by all other security
interests and Liens heretofore, now or at any time hereafter granted by any Borrower Party to the Collateral Agent, any Administrative Agent or any other member of the Lender Group, to the extent provided in the Security Documents under which such
Liens arise. 
 Section 2.14 Maximum Rate of Interest. The Borrowers and the Lender Group hereby agree and stipulate
that the only charges imposed upon the Borrowers for the use of money in connection with this Agreement are and shall be the specific interest and fees described in this Article 2 and in any other Loan Document. Notwithstanding the foregoing,
the Borrowers and the Lender Group further agree and stipulate that all closing fees, agency fees, syndication fees, facility fees, underwriting fees, default charges, late charges, funding or “breakage” charges, increased cost charges,
attorneys’ fees and reimbursement for costs and expenses paid by any member of the Lender Group to third parties or for damages incurred by the Lender Group, or any of them, are charges to compensate the Lender Group for underwriting and
administrative services and costs or losses performed or incurred, and to be performed and incurred, by the Lender Group in connection with this Agreement and the other Loan Documents and shall under no circumstances be deemed to be charges for the
use of money pursuant to any Applicable Law. In no event shall the amount of interest and other charges for the use of money payable under this Agreement exceed the maximum amounts permissible under any law that a court of competent jurisdiction
shall, in a final determination, deem applicable. The Borrowers and the Lender Group, in executing and delivering this Agreement, intend legally to agree upon the rate or rates of interest and other charges for the use of money and manner of payment
stated within it; provided, however, that, anything contained herein to the contrary notwithstanding, if the amount of such interest and other charges for the use of money or manner of payment exceeds the maximum amount allowable under
Applicable Law, then, ipso facto as of the Agreement Date, the Borrowers are and shall be liable only for the payment of such maximum amount as allowed by law, and payment received from the Borrowers in excess of such legal maximum amount, whenever
received, shall be applied to reduce the principal balance of the Revolving Loans to the extent of such excess. 

Section 2.15 Letters of Credit 
 (a) Until the maturity or termination of the Revolving Loan Commitments, the Issuing Bank, in reliance upon the agreements of the other Lenders pursuant to subsections (d) and (e) of this
Section 2.15, may, in its sole discretion, issue, at the request of the Borrowers, Letters of Credit for the account of the Borrowers on the terms and conditions hereinafter set forth; provided that (i) each Letter of Credit shall
expire on the earlier of (A) the date one year after the date of issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (B) the date that is five
(5) Business Days prior to the Maturity Date of the Revolving Credit Facility; (ii) each Letter of Credit shall be in a stated amount of at least $500,000; and (iii) the Borrowers may not request any Letter of Credit if, after giving
effect to such issuance, (A) the aggregate Letter of Credit Obligations would exceed the aggregate Letter of Credit Commitment or (B) the aggregate outstanding Revolving Loans of all Lenders would exceed the Revolving Loan Facility. Each
Revolving Facility Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Issuing Bank without recourse a participation in each Letter of Credit equal to such Lender’s pro rata share of the aggregate
amount available to be drawn under such Letter of Credit (i) on the Agreement Date with respect to all Existing Letters of Credit and (ii) on the date of issuance with respect to all other Letters of Credit. Each issuance of a Letter of
Credit shall be deemed to utilize the Revolving Loan Commitment of each Lender by an amount equal to the amount of such participation. 

  
 70 









 (b) To request the issuance of a Letter of Credit (or any amendment, renewal
or extension of an outstanding Letter of Credit), the Borrowers shall give the Issuing Bank and the Administrative Agent irrevocable written notice at least three (3) Business Days prior to the requested date of such issuance specifying the
date (which shall be a Business Day) such Letter of Credit is to be issued (or amended, renewed or extended, as the case may be), the expiration date of such Letter of Credit, the amount of such Letter of Credit, the name and address of the
beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. In addition to the satisfaction of the conditions in Section 4.3, the issuance of such Letter of Credit (or
any amendment which increases the amount of such Letter of Credit) will be subject to the further conditions that such Letter of Credit shall be in such form and contain such terms as the Issuing Bank shall approve and that the Borrowers shall have
executed and delivered any additional applications, agreements and instruments relating to such Letter of Credit as the Issuing Bank shall reasonably require; provided that in the event of any conflict between such applications, agreements or
instruments and this Agreement, the terms of this Agreement shall control. 
 (c) At least two (2) Business
Days prior to the issuance of any Letter of Credit, the Issuing Bank will confirm with the Revolving Facility Administrative Agent (by telephone or in writing) that the Revolving Facility Administrative Agent has received such notice, and, if not,
the Issuing Bank will provide the Administrative Agent with a copy thereof. Unless the Issuing Bank has received notice from the Revolving Facility Administrative Agent, on or before the Business Day immediately preceding the date the Issuing Bank
is to issue the requested Letter of Credit, directing the Issuing Bank not to issue the Letter of Credit because such issuance is not then permitted hereunder because of the limitations set forth in subsection (a) of this
Section 2.15 or that one or more conditions specified in Section 4.3 are not then satisfied, then, subject to the terms and conditions hereof, the Issuing Bank shall, on the requested date, issue such Letter of Credit in
accordance with the Issuing Bank’s usual and customary business practices. 

  
 71 









 (d) The Issuing Bank shall examine all documents purporting to represent a
demand for payment under a Letter of Credit promptly following its receipt thereof. The Issuing Bank shall notify the Borrowers and the Revolving Facility Administrative Agent of such demand for payment and whether the Issuing Bank has made or will
make a disbursement under such Letter of Credit Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrowers of their obligation to reimburse the Issuing Bank and the Revolving
Facility Lenders with respect to such Letter of Credit Disbursement. The Borrowers shall be irrevocably and unconditionally obligated to reimburse the Issuing Bank for any Letter of Credit Disbursements paid by the Issuing Bank in respect of such
drawing, without presentment, demand or other formalities of any kind. Unless the Borrowers shall have notified the Issuing Bank and the Revolving Facility Administrative Agent prior to 11:00 a.m. on the Business Day immediately prior to the date on
which such drawing is honored that the Borrowers intend to reimburse the Issuing Bank for the amount of such drawing in funds other than from the proceeds of Revolving Loans, the Borrowers shall be deemed to have timely given a Request for Loan to
the Revolving Facility Administrative Agent requesting the Revolving Facility Lenders to make a Base Rate Loan on the date on which such drawing is honored in an exact amount due to the Issuing Bank; provided that for purposes solely of such
Borrowing, the conditions precedent set forth in Section 4.3 hereof shall not be applicable. The Revolving Facility Administrative Agent shall notify the Revolving Facility Lenders of such Borrowing in accordance with
Section 2.2, and each Lender shall make the proceeds of its Base Rate Loan included in such borrowing available to the Revolving Facility Administrative Agent for the account of the Issuing Bank in accordance with
Section 2.2. The proceeds of such Base Rate Loan shall be applied directly by the Revolving Facility Administrative Agent to reimburse the Issuing Bank for such Letter of Credit Disbursement. 

(e) If for any reason a Base Rate Loan may not be (as determined in the sole discretion of the Revolving Facility
Administrative Agent), or is not, made in accordance with the foregoing provisions, then each Revolving Facility Lender (other than the Issuing Bank) shall be obligated to fund the participation that such Revolving Facility Lender purchased pursuant
to subsection (a) of this Section 2.15 in an amount equal to its pro rata share of such Letter of Credit Disbursement on and as of the date which such Base Rate Borrowing should have occurred. Each Revolving Facility Lender’s
obligation to fund its participation shall be absolute and unconditional and shall not be affected by any circumstance, including, without limitation, (i) any set-off, counterclaim, recoupment, defense or other right that such Lender or any
other Person may have against the Issuing Bank or any other Person for any reason whatsoever, (ii) the existence of a Default or an Event of Default or the termination of the Revolving Loan Facility, (iii) any adverse change in the
condition (financial or otherwise) of the Borrowers or any of their Subsidiaries, (iv) any breach of this Agreement by the Borrowers or any other Lender, (v) any amendment, renewal or extension of any Letter of Credit or (vi) any
other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. On the date that such participation is required to be funded, each Revolving Facility Lender shall promptly transfer, in immediately available funds,
the amount of its participation to the Revolving Facility Administrative Agent for the account of the Issuing Bank. Whenever, at any time after the Issuing Bank has received from any such Revolving Facility Lender the funds for its participation in
a Letter of Credit Disbursement, the Issuing Bank (or the Revolving Facility Administrative Agent on its behalf) receives any payment on account thereof, the Revolving Facility Administrative Agent or the Issuing Bank, as the case may be, will
distribute to such Lender its pro rata share of such payment; provided that if such payment is required to be returned for any reason to the Borrowers or to a trustee, receiver, liquidator, custodian or similar official in any bankruptcy proceeding,
such Revolving Facility Lender will return to the Term Revolving Facility Administrative Agent or the Issuing Bank any portion thereof previously distributed by the Revolving Facility Administrative Agent or the Issuing Bank to it. 

  
 72 









 (f) To the extent that any Revolving Facility Lender shall fail to pay any
amount required to be paid pursuant to subsection (d) or (e) of this Section 2.15 on the due date therefor, such Revolving Facility Lender shall pay interest to the Issuing Bank (through the Revolving Facility Administrative
Agent) on such amount from such due date to the date such payment is made at a rate per annum equal to the Federal Funds Rate; provided that if such Revolving Facility Lender shall fail to make such payment to the Issuing Bank within three
(3) Business Days of such due date, then, retroactively to the due date, such Revolving Facility Lender shall be obligated to pay interest on such amount at the rate set forth in Section 2.3. 

(g) If any Event of Default shall occur and be continuing, on the Business Day that the Borrowers receive notice from the
Revolving Facility Administrative Agent or the Required Resolving Facility Lenders demanding that its reimbursement obligations with respect to the Letters of Credit be Cash Collateralized pursuant to this subsection, the Borrowers shall deposit in
an account with the Revolving Facility Administrative Agent, in the name of the Revolving Facility Administrative Agent and for the benefit of the Issuing Bank and the Revolving Facility Lenders, an amount in cash equal to 105% of the aggregate
Letter of Credit Obligations of all Revolving Facility Lenders as of such date plus any accrued and unpaid fees thereon; provided that such obligation to cash collateralize the reimbursement obligations of the Borrowers with respect to the Letters
of Credit shall become effective immediately, and such deposit shall become immediately due and payable, without demand or notice of any kind, upon the occurrence of any Event of Default with respect to the Borrowers described in
Section 9.1(g) or (h). Such deposit shall be held by the Revolving Facility Administrative Agent as collateral for the payment and performance of the obligations of the Borrowers under this Agreement. The Revolving Facility
Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. The Borrowers agree to execute any documents and/or certificates to effectuate the intent of this subsection. Other than
any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Revolving Facility Administrative Agent and at the Borrowers’ risk and expense, such deposits shall not bear
interest. Interest and profits, if any, on such investments shall accumulate in such account. Cash in such account shall be applied by the Revolving Facility Administrative Agent to reimburse the Issuing Bank for Letter of Credit Disbursements for
which it had not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrowers for the Letter of Credit Obligations at such time or, if the maturity of the Loans has been
accelerated, with the consent of the Required Revolving Facility Lenders, be applied to satisfy other obligations of the Borrowers under this Agreement and the other Loan Documents. If the Borrowers are required to cash collateralize its
reimbursement obligations with respect to the Letters of Credit as a result of the occurrence of an Event of Default, such cash collateral so posted (to the extent not so applied as aforesaid) shall be returned to the Borrowers within three
(3) Business Days after all Events of Default have been cured or waived. 

  
 73 









 (h) The Borrowers’ obligation to reimburse Letter of Credit
Disbursements hereunder shall be absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever and irrespective of any of the following circumstances:

 (i) any lack of validity or enforceability of any Letter of Credit or this Agreement; 

(ii) the existence of any claim, set-off, defense or other right which the Borrowers or any Subsidiary or Affiliate of
the Borrowers may have at any time against a beneficiary or any transferee of any Letter of Credit (or any Persons or entities for whom any such beneficiary or transferee may be acting), any Lender (including the Issuing Bank) or any other Person,
whether in connection with this Agreement or the Letter of Credit or any document related hereto or thereto or any unrelated transaction; 
 (iii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect;

 (iv) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document
to the Issuing Bank that does not comply with the terms of such Letter of Credit; 
 (v) any other event or
circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of set-off against, the Borrowers’ obligations
hereunder; or 
 (vi) the existence of a Default or an Event of Default. 

Neither the Revolving Facility Administrative Agent, the Issuing Bank, any Lender nor any Affiliates of any of the foregoing shall have any liability or
responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to above), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical
terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrowers to the extent of any actual direct damages (as opposed
to special, indirect (including claims for lost profits or other consequential damages), or punitive damages, claims in respect of which are hereby waived by the Borrowers to the extent permitted by applicable law) suffered by the Borrowers that are
caused by the Issuing Bank’s failure to exercise due care when determining whether drafts or other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross
negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised due care in each such determination. In furtherance of the foregoing
and without limiting the generality thereof, the parties agree that, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion,
either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in
strict compliance with the terms of such Letter of Credit. 

  
 74 









 (i) Unless otherwise expressly agreed by the Issuing Bank and the Borrowers
when a Letter of Credit is issued and subject to applicable laws, (i) each standby Letter of Credit shall be governed by the “International Standby Practices 1998” (ISP98) (or such later revision as may be published by the Institute
of International Banking Law & Practice on any date any Letter of Credit may be issued), (ii) each documentary Letter of Credit shall be governed by the Uniform Customs and Practices for Documentary Credits (2007 Revision),
International Chamber of Commerce Publication No. 600 (or such later revision as may be published by the International Chamber of Commerce on any date any Letter of Credit may be issued) and (iii) the Borrowers shall specify the foregoing
in each letter of credit application submitted for the issuance of a Letter of Credit. 
 (j) Existing Letters
of Credit. Subject to the terms and conditions hereof, each Existing Letter of Credit that is outstanding on the Agreement Date, listed on Schedule 1.1(d) shall, effective as of the Agreement Date and without any further action by the
Borrowers, be continued as a Letter of Credit hereunder, from and after the Agreement Date be deemed a Letter of Credit for all purposes hereof and be subject to and governed by the terms and conditions hereof. 

Section 2.16 Bank Products. Any Borrower Party may request and any Lender may, in its sole and absolute discretion, arrange
for such Borrower Party to obtain from such Lender or any Affiliate of such Lender, Bank Products although no Borrower Party is required to do so. If any Bank Products are provided by an Affiliate of any Lender, the Borrower Parties agree to
indemnify and hold the Lender Group, or any of them, harmless from any and all costs and obligations now or hereafter incurred by the Lender Group, or any of them, which arise from any indemnity given by such Lender to any of its Affiliates, as
applicable, related to such Bank Products; provided, however, nothing contained herein is intended to limit the Borrower Parties’ rights, with respect to such Lender or any of its Affiliates, as applicable, if any, which arise as
a result of the execution of documents by and between the Borrower Parties and such Person which relate to any Bank Products. The agreement contained in this Section shall survive termination of this Agreement. The Borrower Parties acknowledge and
agree that the obtaining of Bank Products from any Lender or its Affiliates (a) is in the sole and absolute discretion of such Lender or such Affiliates, and (b) is subject to all rules and regulations of such Lender or such Affiliates.

 Section 2.17 Additional Increase of Commitments; Additional Lenders. 

(a) Increase of the Revolving Loan Commitment. 

  
 75 









 (i) So long as no Event of Default has occurred and is continuing, the
Administrative Borrower may request the right to effectuate increases in the Revolving Loan Commitment (any such increase, a “Commitment Increase”), during the term of this Agreement by delivering a Notice of Requested Commitment
Increase to each Administrative Agent substantially in the form of Exhibit I-1 (a “Notice of Requested Commitment Increase”), provided that, in each case: (A) each Commitment Increase shall be at least
$5,000,000 and in integral multiples of $1,000,000 in excess thereof and (B) the proposed Commitment Increase shall have been consented to in writing by the Revolving Facility Administrative Agent (such consent not to be unreasonably withheld),
each Revolving Facility Lender (if any) who is increasing its portion of the Revolving Loan Commitment and any other bank or financial institution acceptable to the Borrowers and reasonably acceptable to the Revolving Facility Administrative Agent
that has agreed to become a Revolving Facility Lender in respect of all or a portion of the Commitment Increase (a “New Lender”). Each Notice of Requested Commitment Increase shall specify: (1) the amount of the proposed
Commitment Increase and (2) the requested date of the proposed Commitment Increase (which shall be at least ten (10) Business Days from the date of delivery of the Notice of Requested Commitment Increase). Each Notice of Requested
Commitment Increase shall be binding on all Borrowers. Upon the effective date of any Commitment Increase, the Administrative Borrower shall deliver to each Administrative Agent a certificate of the chief financial officer of the Administrative
Borrower certifying that no Default or Event of Default then exists or would be caused thereby. No Commitment Increase shall be effective (x) unless immediately prior to, and after giving effect to the incurrence of such Commitment Increase and
any transaction consummated in connection therewith, the Senior Secured Leverage Ratio is no greater, calculated on a pro forma basis, than 4.50 to 1.00, (y) the Commitment Increase shall be on the same terms as the existing Revolving Loan
Commitments and (z) until the Revolving Facility Administrative Agent shall have received amendments to this Agreement and the other Loan Documents, commitments of Revolving Facility Lenders or New Lenders in an aggregate amount equal to such
Commitment Increase, Lender Agreements for each Revolving Facility Lender or New Lender committing to such Commitment Increase, any upfront fees to be paid to the Revolving Facility Lenders committing to such Commitment Increase, and, if requested,
opinion letters, Revolving Loan Notes and such other agreements, documents and instruments requested by and reasonably satisfactory to the Revolving Facility Administrative Agent in its Permitted Discretion evidencing and setting forth the
conditions of such Commitment Increase. 
 (ii) If the Revolving Facility Administrative Agent approves a
proposed Commitment Increase, the Revolving Facility Administrative Agent shall deliver a copy of the Notice of Requested Commitment Increase relating thereto to each Revolving Facility Lender. No Revolving Facility Lender (or any successor thereto)
shall have any obligation to increase its portion of the Revolving Loan Commitment or its other obligations under this Agreement or the other Loan Documents, and any decision by a Revolving Facility Lender to increase its portion of the Revolving
Loan Commitment shall be made in its sole discretion independently from any other Lender. If the Revolving Facility Administrative Agent receives commitments from the Revolving Facility Lenders or the New Lenders in excess of the amount of the
proposed Commitment Increase, the Revolving Facility Administrative Agent shall, in consultation with the Borrower, have the right, to reduce and reallocate (within the minimum and maximum amounts specified by each such Revolving Facility Lender or
New Lender in its notice to the Revolving Facility Administrative Agent) the shares of such Commitment Increase of the Revolving Facility Lenders or New Lenders willing to fund the proposed Commitment Increase so that the total committed shares of
the proposed Commitment Increase equals the proposed Commitment Increase. The Revolving Facility Administrative Agent shall notify each Revolving Facility Lender or New Lender, as the case may be, whether its proposed share of the proposed
Commitment Increase has been accepted and, if so, the amount of its share of such Commitment Increase, and such Revolving Facility Lender shall thereafter execute and deliver a Lender Agreement with respect to its respective share of such Commitment
Increase. 

  
 76 









 (iii) Notwithstanding anything to the contrary contained herein, each
Commitment Increase meeting the conditions set forth in Section 2.17(a)(i) shall not require the consent of any Lender other than those Revolving Facility Lenders, if any, which have agreed to increase their portions of the Revolving
Loan Commitment in connection with such Commitment Increase and shall not constitute an amendment, modification or waiver that is subject to Section 11.12 and shall be effective as of the later of (a) the date specified in the
applicable Notice of Requested Commitment Increase and (b) the date upon which the foregoing conditions shall have been satisfied or waived by each Administrative Agent and the Revolving Facility Lenders which have agreed to increase their
portions of the Revolving Loan Commitment, or by the requisite Lenders in accordance with Section 11.12 in the case of a waiver of an Event of Default, as applicable. 

(iv) Effect of Commitment Increase. After giving effect to any Commitment Increase, the outstanding Revolving Loans
may not be held pro rata in accordance with the new Revolving Loan Commitment. In order to remedy the foregoing, on the effective date of each Commitment Increase, the Revolving Facility Lenders (including any New Lenders) shall reallocate the
Revolving Loans owed to them among themselves so that, after giving effect thereto, the Revolving Loans will be held by the Revolving Facility Lenders (including any New Lenders) on a pro rata basis in accordance with their respective Commitment
Ratios (after giving effect to such Commitment Increase). Each Revolving Facility Lender agrees to wire immediately available funds to the Revolving Facility Administrative Agent in accordance with this Agreement as may be required by the Revolving
Facility Administrative Agent in connection with the foregoing. Notwithstanding the provisions of Section 11.5, the reallocations so made by each Revolving Facility Lender whose Commitment Ratio has increased shall be deemed to be a
purchase of a corresponding amount of the Revolving Loans of the Revolving Facility Lender or Lenders whose Commitment Ratio have decreased and shall not be considered an assignment for purposes of Section 11.5. 

  
 77 









 (b) Incremental Loans. 

(i) The Borrowers may at any time or from time to time after the Agreement Date, upon not less than five (5) Business
Days written notice to each Administrative Agent (whereupon the applicable Administrative Agent shall promptly deliver a copy of such notice to each of the applicable Lenders), request that one or more new tranche of Term Loans (the
“Incremental Term Loans”) or one or more new tranche of Revolving Loans be made available to the Borrowers (the “Incremental Revolving Loans”, together the “Incremental Loans”) in an aggregate
amount, together with any Funded Debt incurred pursuant to Section 8.1(r), not to exceed $380,000,000, provided that, immediately prior to, and after giving effect to the incurrence of such Incremental Loans and any transaction
consummated in connection therewith, (A) the representations and warranties contained in Article V and the other Loan Documents are true and correct in all material respects, (B) no Default or Event of Default shall have
occurred and be continuing and (C) the Senior Secured Leverage Ratio is no greater, calculated on a pro forma basis, than 4.50 to 1.00. Each incurrence of Incremental Loans shall be in an aggregate principal amount that is not less than
$5,000,000. Incremental Loans (w) shall rank pari passu in right of payment and of security with the initial Term Loans incurred on the Agreement Date (the “Initial Term Loans”) and the existing Revolving Loan Commitments
(though such Incremental Loans may be secured by less than all of the Collateral), (x) shall not mature earlier than the Maturity Date with respect to the Initial Term Loans or existing Revolving Loan Commitments, (y) shall be treated
substantially the same as the Initial Term Loans and the existing Revolving Loan Commitments, as applicable, (including, without limitation, with respect to mandatory and voluntary prepayments) and (z) shall have interest rates and amortization
schedules as determined by the Borrowers and the lenders thereof; provided further that, as of the date of the incurrence of any Incremental Term Loan (1) the Weighted Average Life to Maturity of such Incremental Term Loan shall not be
shorter than that of the Initial Term Loans and (2) in the event that the All-In Yield applicable to such Incremental Term Loans exceeds the All-In Yield of the Initial Term Loans by more than 50 basis points, the interest rate margins for
existing such Initial Term Loans to the extent necessary so that the All-In Yield of such Loans is equal to the All-In Yield of the applicable Incremental Term Loans minus 50 basis points. 

(ii) Each notice from the Borrowers pursuant to this Section 2.17 shall set forth the requested amount and
proposed terms of the relevant Incremental Loans. Incremental Loans may be made by any applicable existing Lender (and each applicable existing Lender will have the right, but not an obligation, on terms permitted in this Section 2.17
and otherwise on terms reasonably acceptable to the applicable Administrative Agent, to make a portion of any Incremental Loan equal to the amount of Incremental Loans so requested by the Borrowers multiplied by such Lender’s Commitment Ratio)
or by any other bank or other financial institution reasonably acceptable to the Borrowers and the applicable Administrative Agent (any such other bank or other financial institution being called an “Additional Lender”). Incremental
Loans shall become Loans under this Agreement pursuant to an amendment (an “Incremental Amendment”) to this Agreement and, as appropriate, the other Loan Documents, executed by the Borrowers, each Lender agreeing to provide such
Loans, if any, each Additional Lender, if any, and each Administrative Agent. The Incremental Amendment may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or
appropriate, in the reasonable opinion of each Administrative Agent and the Borrowers, to effect the provisions of this Section 2.17. The effectiveness of any Incremental Amendment and the borrowings of Incremental Loans under this
Agreement (as amended by such Incremental Amendment) shall be subject to the satisfaction of such conditions as the parties thereto shall agree. The Borrowers will use the proceeds of any Incremental Loans for any purposes not prohibited by this
Agreement. No Lender shall be obligated to provide any Incremental Loans unless it so agrees. 

  
 78 









 (iii) This Section 2.17 shall supersede any provisions in
Section 2.10 or Section 11.12 to the contrary. 
 Section 2.18 Defaulting Lenders .
Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender: 

(a) the Unused Line Fees shall cease to accrue on the portion of the Revolving Loan Commitment held by such Lender so long
as it is a Defaulting Lender (except to the extent it is payable to the Issuing Bank pursuant to clause (b)(v) below); 
 (b) if any Swing Line Loans or Letter of Credit Obligations exist at the time a Lender becomes a Defaulting Lender then: 

(i) all or any part of such Swing Line Loans and Letter of Credit Obligations shall be reallocated among the
non-Defaulting Lenders in accordance with their respective Commitment Ratio but only to the extent the Aggregate Revolving Credit Obligations held by of all non-Defaulting Lenders’ plus the Commitment Ratio of such Defaulting Lender’s
Swing Line Loan and Letter of Credit Obligations does not exceed the portion of the Revolving Loan Commitment held by the non-Defaulting Lenders and the conditions precedent to borrowing pursuant to Section 4.2 are met; 

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, Borrowers shall
within one Business Day following notice by the applicable Administrative Agent (x) first, prepay the Swing Line Loan in an amount equal to such Defaulting Lender’s pro rata share of the Swing Line Loan and (y) second, cash
collateralize the Letters of Credit Obligations in an amount equal to such Defaulting Lender’s pro rata share of the Letter of Credit Obligations (after giving effect to any partial reallocation pursuant to clause (i) above) in an amount
equal to one hundred five percent (105%) of the Letter of Credit Obligations for so long as such Letter of Credit Obligations are outstanding; 
 (iii) if any portion of such Defaulting Lender’s pro rata share of the Letter of Credit Obligations is cash collateralized pursuant to clause (ii) above, Borrowers shall not be required
to pay the fees described in Section 2.4(c) with respect to such portion of such Defaulting Lender’s Letter of Credit Obligations so long as it is cash collateralized; 

  
 79 









 (iv) if any portion of such Defaulting Lender’s Letter of Credit
Obligations is reallocated to the non-Defaulting Lenders pursuant to clause (i) above, then the Letter of Credit Fees under Section 2.4(c) with respect to such portion shall be allocated among the non-Defaulting Lenders in
accordance with their Commitment Ratio; 
 (v) if any portion of such Defaulting Lender’s pro rata share of
the Letter of Credit Obligations is neither cash collateralized nor reallocated pursuant to this Section 2.18(b), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, the Unused Line Fee that
otherwise would have been payable to such Defaulting Lender (on account of the portion of such Defaulting Lender’s Revolving Loan Commitment that was utilized by such Letter of Credit Obligations) and the Letter of Credit Fee under
Section 2.4(c) payable with respect to such Defaulting Lender’s Letter of Credit Obligations shall be payable to the Issuing Bank until such Letter of Credit Obligations are cash collateralized and/or reallocated in accordance
herewith; and 
 (vi) so long as any Lender is a Defaulting Lender, the Swing Line Bank shall not be required to
fund any Swing Line Loan and the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Revolving Loan Commitment of the non-Defaulting
Lenders and/or cash collateralized in accordance with this Section 2.18(b), and participations in any such newly issued or increased Letter of Credit or newly made Swing Line Loan shall be allocated among non-Defaulting Lenders in
accordance with their respective Commitment Ratio (and Defaulting Lenders shall not participate therein); and 

(c) any amount payable to such Defaulting Lender hereunder (whether on account of principal, interest, fees or otherwise)
may, in lieu of being distributed to such Defaulting Lender, be retained by the applicable Administrative Agent in a segregated non-interest bearing account and, subject to any Applicable Law, be applied at such time or times as may be determined by
such Administrative Agent (i) first, to the payment of any amounts owing by such Defaulting Lender to such Administrative Agent hereunder, (ii) second, pro rata, to the payment of any amounts owing by such Defaulting Lender
to the Issuing Bank or Swing Line Bank hereunder, (iii) third, to the funding of any Loan or the funding or cash collateralization of any participation in any Swing Line Loan or Letter of Credit in respect of which such Defaulting Lender
has failed to fund its portion thereof as required by this Agreement, as determined by such Administrative Agent, (iv) fourth, if so determined by such Administrative Agent and the Administrative Borrower, held in such account as cash
collateral for future funding obligations of the Defaulting Lender under this Agreement, (v) fifth, pro rata, to the payment of any amounts owing to Borrowers or the Lenders as a result of any judgment of a court of competent
jurisdiction obtained by the Borrowers or any Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement and (vi) sixth, to such Defaulting Lender or as otherwise
directed by a court of competent jurisdiction; provided that if such payment is (x) a prepayment of the principal amount of any Loans or Letter of Credit Obligations in respect of Letters of Credit which a Defaulting Lender has funded
its participation obligations and (y) made at a time when the conditions set forth in Section 4.3 are satisfied, such payment shall be applied solely to prepay the Loans of, and Letter of Credit Obligations owed to, all
non-Defaulting Lenders, based on their Commitment Ratio, prior to being applied to the prepayment of any Loans, or Letter of Credit Obligations owed to, any Defaulting Lender. 

  
 80 









 In the event that the applicable Administrative Agent, the Borrowers, the Issuing Bank or the Swing Line
Bank, as the case may be, each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Swing Line Loans and Letter of Credit Obligations of the Lenders shall be readjusted to
reflect the inclusion of such Lender’s portion of the Revolving Loan Commitment and on such date such Lender shall purchase at par such of the Loans of the other Lenders as the applicable Administrative Agent shall determine may be necessary in
order for such Lender to hold such Loans in accordance with its Commitment Ratio. The rights and remedies against a Defaulting Lender under this Section 2.18 are in addition to other rights and remedies that the Borrowers, the applicable
Administrative Agent, the Issuing Bank, the Swing Line Bank and the non-Defaulting Lenders may have against such Defaulting Lender. The arrangements permitted or required by this Section 2.18 shall be permitted under this Agreement,
notwithstanding any limitation on Liens or the pro rata sharing provisions or otherwise. 
 ARTICLE 3. 

GUARANTY 

Section 3.1 Guaranty. 
 (a) Each Guarantor hereby irrevocably guarantees to the applicable Administrative Agent, for the benefit of the Lender Group, the full and prompt payment of the Obligations, including, without limitation,
any interest therein (including, without limitation, interest as provided in this Agreement, accruing after the filing of a petition initiating any Insolvency Proceedings, whether or not such interest accrues or is recoverable against the Borrowers
after the filing of such petition for purposes of the Bankruptcy Code or is an allowed claim in such proceeding), plus documented, reasonable attorneys’ fees and expenses if the obligations represented by this Guaranty are collected by law,
through an attorney-at-law, or under advice therefrom. 
 (b) Regardless of whether any proposed guarantor or any other Person
shall become in any other way responsible to the Lender Group, or any of them, for or in respect of the Obligations or any part thereof, and regardless of whether or not any Person now or hereafter responsible to the Lender Group, or any of them,
for the Obligations or any part thereof, whether under this Guaranty or otherwise, shall cease to be so liable, each Guarantor hereby declares and agrees that this Guaranty shall be a joint and several obligation, shall be a continuing guaranty and
shall be operative and binding until the Obligations shall have been indefeasibly paid in full in cash (or in the case of Letter of Credit Obligations, secured through delivery of cash collateral in an amount equal to one hundred five percent
(105%) of the Letter of Credit Obligations) and the Revolving Loan Commitment shall have been terminated. 

  
 81 









 (c) Each Guarantor absolutely, unconditionally and irrevocably waives any and all right to
assert any defense (other than the defense of payment in cash in full or performance, to the extent of its obligations hereunder, or a defense that such Guarantor’s liability is limited as provided in Section 3.1(g)), set-off,
counterclaim or cross-claim of any nature whatsoever with respect to this Guaranty or the obligations of the Guarantors under this Guaranty or the obligations of any other Person or party (including, without limitation, the Borrowers) relating to
this Guaranty or the obligations of any of the Guarantors under this Guaranty or otherwise with respect to the Obligations in any action or proceeding brought by any Administrative Agent or any other member of the Lender Group to collect the
Obligations or any portion thereof, or to enforce the obligations of any of the Guarantors under this Guaranty. 
 (d) The
Lender Group, or any of them, may from time to time, without exonerating or releasing any Guarantor in any way under this Guaranty, (i) take such further or other security or securities for the Obligations or any part thereof as they may deem
proper, or (ii) release, discharge, abandon or otherwise deal with or fail to deal with any Guarantor of the Obligations or any security or securities therefor or any part thereof now or hereafter held by the Lender Group, or any of them, or
(iii) amend, modify, extend, accelerate or waive in any manner any of the provisions, terms, or conditions of the Loan Documents, all as they may consider expedient or appropriate in their sole discretion. Without limiting the generality of the
foregoing, or of Section 3.1(e), it is understood that the Lender Group, or any of them, may, without exonerating or releasing any Guarantor, give up, modify or abstain from perfecting or taking advantage of any security for the
Obligations and accept or make any compositions or arrangements, and realize upon any security for the Obligations when, and in such manner, and with or without notice, all as such Person may deem expedient. 

(e) Each Guarantor acknowledges and agrees that no change in the nature or terms of the Obligations or any of the Loan Documents, or
other agreements, instruments or contracts evidencing, related to or attendant with the Obligations (including any novation), shall discharge all or any part of the liabilities and obligations of such Guarantor pursuant to this Guaranty; it being
the purpose and intent of the Guarantors and the Lender Group that the covenants, agreements and all liabilities and obligations of each Guarantor hereunder are absolute, unconditional and irrevocable under any and all circumstances. Without
limiting the generality of the foregoing, each Guarantor agrees that until each and every one of the covenants and agreements of this Guaranty is fully performed, and without possibility of recourse, whether by operation of law or otherwise, such
Guarantor’s undertakings hereunder shall not be released, in whole or in part, by any action or thing which might, but for this paragraph of this Guaranty, be deemed a legal or equitable discharge of a surety or guarantor, or by reason of any
waiver, omission of the Lender Group, or any of them, or their failure to proceed promptly or otherwise, or by reason of any action taken or omitted by the Lender Group, or any of them, whether or not such action or failure to act varies or
increases the risk of, or affects the rights or remedies of, such Guarantor or by reason of any further dealings between the Borrowers, on the one hand, and any member of the Lender Group, on the other hand, or any other guarantor or surety, and
such Guarantor hereby expressly waives and surrenders any defense to its liability hereunder, or any right of counterclaim or offset of any nature or description which it may have or may exist based upon, and shall be deemed to have consented to,
any of the foregoing acts, omissions, things, agreements or waivers. 

  
 82 









 (f) The Lender Group, or any of them, may, without demand or notice of any kind upon or to
any Guarantor, at any time or from time to time when any amount shall be due and payable hereunder by any Guarantor following and during the continuance of an Event of Default, if the Borrowers shall not have timely paid any of the Obligations (or
in the case of Letter of Credit Obligations, secured through delivery of cash collateral in an amount equal to one hundred five percent (105%) of the Letter of Credit Obligations), set-off and appropriate and apply to any portion of the
Obligations hereby guaranteed, and in such order of application as the applicable Administrative Agent may from time to time elect in accordance with this Agreement, any deposits, property, balances, credit accounts or moneys of any Guarantor in the
possession of any member of the Lender Group or under their respective control for any purpose. If and to the extent that any Guarantor makes any payment to any Administrative Agent or any other Person pursuant to or in respect of this Guaranty, any
claim which such Guarantor may have against any Borrower by reason thereof shall be subject and subordinate to the prior payment in full of the Obligations to the satisfaction of the Lender Group. 

(g) The creation or existence from time to time of Obligations in excess of the amount committed to or outstanding on the date of this
Guaranty is hereby authorized, without notice to any Guarantor, and shall in no way impair or affect this Guaranty or the rights of the Lender Group herein. It is the intention of each Guarantor and each Administrative Agent that each
Guarantor’s obligations hereunder shall be, but not in excess of, the Maximum Guaranteed Amount (as herein defined). The “Maximum Guaranteed Amount” with respect to any Guarantor, shall mean the maximum amount which could be
paid by such Guarantor without rendering this Guaranty void or voidable as would otherwise be held or determined by a court of competent jurisdiction in any action or proceeding involving any state or Federal bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance or other similar laws relating to the insolvency of debtors. 
 (h) Upon the bankruptcy or
winding up or other distribution of assets of any Borrower, or of any surety or guarantor (other than the applicable Guarantor) for any Obligations of the Borrowers to the Lender Group, or any of them, the rights of any Administrative Agent against
any Guarantor shall not be affected or impaired by the omission of any member of the Lender Group to prove its claim, or to prove the full claim, as appropriate, against any Borrower, or any other Borrower or any such other guarantor or surety, and
any Administrative Agent may prove such claims as it sees fit and may refrain from proving any claim and in its discretion may value as it sees fit or refrain from valuing any security held by it without in any way releasing, reducing or otherwise
affecting the liability to the Lender Group of each of the Guarantors. 

  
 83 









 (i) Each Guarantor hereby absolutely, unconditionally and irrevocably expressly waives,
except to the extent such waiver would be expressly prohibited by Applicable Law, the following: (i) notice of acceptance of this Guaranty, (ii) notice of the existence or creation of all or any of the Obligations, (iii) presentment,
demand, notice of dishonor, protest and all other notices whatsoever (other than notices expressly required hereunder or under any other Loan Document to which any Guarantor is a party), (iv) all diligence in collection or protection of or
realization upon the Obligations or any part thereof, any obligation hereunder, or any security for any of the foregoing, (v) until the Obligations shall have been paid in full in cash (or, in the case of a Letter of Credit Obligation, secured
through delivery of cash collateral in an amount equal to one hundred five percent (105%) of the Letter of Credit Obligations, all rights to enforce any remedy which the Lender Group, or any of them, may have against any Borrower and
(vi) until the Obligations shall have been paid in full in cash (or in the case of a Letter of Credit Obligations, secured through delivery of cash collateral in an amount equal to one hundred five percent (105%) of the Letter of Credit
Obligations), all rights of subrogation, indemnification, contribution and reimbursement from the Borrowers for amounts paid hereunder and any benefit of, or right to participate in, any collateral or security now or hereinafter held by the Lender
Group, or any of them, in respect of the Obligations. If a claim is ever made upon any member of the Lender Group for the repayment or recovery of any amount or amounts received by such Person in payment of any of the Obligations and such Person
repays all or part of such amount by reason of (A) any judgment, decree or order of any court or administrative body having jurisdiction over such Person or any of its property, or (B) any settlement or compromise of any such claim
effected by such Person with any such claimant, including any Borrower, then in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding upon such Guarantor, notwithstanding any revocation
hereof or the cancellation of any promissory note or other instrument evidencing any of the Obligations, and such Guarantor shall be and remain obligated to such Person hereunder for the amount so repaid or recovered to the same extent as if such
amount had never originally been received by such Person. 
 (j) This Guaranty is a continuing guaranty of the Obligations and
all liabilities to which it applies or may apply under the terms hereof and shall be conclusively presumed to have been created in reliance hereon. No failure or delay by any member of the Lender Group in the exercise of any right, power, privilege
or remedy shall operate as a waiver thereof, and no single or partial exercise by any Administrative Agent of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy and no course of dealing
between any Guarantor and any member of the Lender Group shall operate as a waiver thereof. No action by any member of the Lender Group permitted hereunder shall in any way impair or affect this Guaranty. For the purpose of this Guaranty, the
Obligations shall include, without limitation, all Obligations of the Borrowers to the Lender Group, notwithstanding any right or power of any third party, individually or in the name of any Borrower and the Lender Group, or any of them, to assert
any claim or defense as to the invalidity or unenforceability of any such Obligation, and no such claim or defense shall impair or affect the obligations of any Guarantor hereunder. 

(k) This is a guaranty of payment and not of collection. In the event any Administrative Agent makes a demand upon any Guarantor in
accordance with the terms of this Guaranty, such Guarantor shall be held and bound to such Administrative Agent directly as debtor in respect of the payment of the amounts hereby guaranteed. All costs and expenses, including, without limitation,
reasonable attorneys’ fees and expenses, incurred by any Administrative Agent in obtaining performance of or collecting payments due under this Guaranty shall be deemed part of the Obligations guaranteed hereby. 

  
 84 









 (l) Each Subsidiary Guarantor is a direct or indirect wholly owned Domestic Subsidiary of a
Borrower. Each Guarantor expressly represents and acknowledges that any financial accommodations by the Lender Group to the Borrowers, including, without limitation, the extension of credit, are and will be of direct interest, benefit and advantage
to such Guarantor. 
 (m) Each Guarantor shall be entitled to subrogation and contribution rights from and against the Borrowers
to the extent any Guarantor is required to pay to any member of the Lender Group any amount in excess of the Loans advanced directly to, or other Obligations incurred directly by, such Guarantor or as otherwise available under Applicable Law;
provided, however, that such subrogation and contribution rights are and shall be subject to the terms and conditions of this Section 3.1 and Section 13.4. The payment obligation of a Guarantor to any other
Guarantor under any Applicable Law regarding contribution rights among co-obligors or otherwise shall be subordinate and subject in right of payment to the prior payment in full of the obligations of such Guarantor under the other provisions of this
Guaranty, and such Guarantor shall not exercise any right or remedy with respect to such rights until payment and satisfaction in full of all such obligations. 
 Section 3.2 Special Provisions Applicable to Subsidiary Guarantors . Pursuant to Section 6.17 of this Agreement, any new Domestic Subsidiary of any Borrower other than an
Unrestricted Subsidiary is required to enter into this Agreement by executing and delivering to each Administrative Agent a Guaranty Supplement. Upon the execution and delivery of a Guaranty Supplement by such new Domestic Subsidiary, such Domestic
Subsidiary shall become a Guarantor and Borrower Party hereunder with the same force and effect as if originally named as a Guarantor or Borrower Party herein. The execution and delivery of any Guaranty Supplement (or any other supplement to any
Loan Document delivered in connection therewith) adding an additional Guarantor as a party to this Agreement or any other Applicable Loan Document shall not require the consent of any other party hereto. The rights and obligations of each party
hereunder shall remain in full force and effect notwithstanding the addition of any new Guarantor hereunder.

a Materially Adverse Effect. None of such Necessary Authorizations is the subject of any pending or, to the best of each Borrower Party’s knowledge, threatened attack, application, objection or any other petition with a Governmental Authority
for revocation, termination, suspension, denial or material modification of a Necessary Authorization, by the grantor of the Necessary Authorization except, other than with respect to the transactions contemplated by the Loan Documents, where the

in such Borrower Party not being authorized to own or operate any material portion of its Telecommunications Assets, or incur or remain liable with respect to any of the Obligations or Liens granted as security therefore. No Borrower Party has any
knowledge of any event or circumstance constituting (i) noncompliance (or any Person alleging noncompliance) with any rule or regulation of the FCC and (ii) noncompliance (or any Person alleging noncompliance) with any applicable
State Telecommunications Laws, except any noncompliance which has not had, and could not reasonably be expected to have, a Materially Adverse Effect or result in any Borrower Party not being authorized to own or operate any material portion of the

Party or such Subsidiary, as applicable, is currently contesting in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of such Borrower Party or such Subsidiary, as the
case may be. As of the Agreement Date, no adjustment relating to any tax returns has been proposed formally or informally by any Governmental Authority and, to the knowledge of each Borrower Party no basis exists for any such adjustment, except as
reflected in the charges, accruals and reserves on the books of the Borrower Parties and their Subsidiaries or except such as could not reasonably be expected to have a Materially Adverse Effect. Except as described in Schedule 5.1(j), no
Borrower Party has executed or filed with the Internal Revenue Service or any other Governmental Authority any agreement or other document extending, or having the effect of extending, the period for assessment or collection of any taxes. Except as
set forth on Schedule 5.1(j), as of the Agreement Date, none of the Borrower Parties and their respective predecessors are liable for any taxes: (i) under any agreement (including any tax sharing agreements) or (ii) to each Borrower
Party’s knowledge, as a transferee. As of the Agreement Date, no Borrower Party has agreed, or been requested, to make any adjustment under Code Section 481(a), by reason of a change in accounting method or otherwise, which would have a
Materially Adverse Effect. 
 (k) Financial Statements. The Borrowers have furnished, or have caused to be
furnished, to the Lenders (i) the Audited Financial Statements which are complete and correct in all material respects and present fairly in accordance with GAAP the respective financial positions of Zayo and AboveNet for the fiscal years
covered thereby and the results of operations for the fiscal years then ended, (ii) the Unaudited Financial Statements which are complete and correct in all material respects and present fairly in accordance with GAAP, subject to normal year
end adjustments, the respective financial positions of Zayo and AboveNet for the periods covered thereby, and the results of operations for the respective twelve-month periods then ended and (iii) the Pro Forma Financial Statements which have
been prepared in good faith, based on assumptions believed by the Borrowers to be reasonable as of the date hereof, and present fairly in all material respects on a Pro Forma Basis the estimated financial position of Zayo and its Subsidiaries as at
March 31, 2012 and the estimated results of operations for the periods covered thereby, assuming that the Transactions had actually occurred at the beginning of the periods covered thereby.

 (l) No Adverse Change. Since June 30, 2011, there has occurred
no event which has had or could reasonably be expected to have a Materially Adverse Effect. 
 (m) Investments
and Guaranties. As of the Agreement Date, no Borrower Party or any Subsidiary of a Borrower Party owns any Equity Interests of any Person except as disclosed on Schedules 5.1(c)-1 and 5.1(c)-2, or has outstanding loans or advances
to, or guaranties of the obligations of, any Person, except as reflected in the financial statements referred to in Section 5.1(k) or disclosed on Schedule 5.1(m). 

(n) Liabilities, Litigation, etc. As of the Agreement Date, except for liabilities incurred in the normal course of
business, no Borrower Party or any Subsidiary of any Borrower Party has any material (individually or in the aggregate) liabilities, direct or contingent, except as disclosed or referred to in the financial statements referred to in
Section 5.1(k) or with respect to the Obligations or the Senior Note Indebtedness. As of the Agreement Date, except as described on Schedules 5.1(n), there is no litigation, legal or administrative proceeding, or, to the knowledge
of the Borrower Parties, investigation or other action of any nature, pending or, to the knowledge of the Borrower Parties, threatened against or affecting any Borrower Party, any Subsidiary of any Borrower Party or any of their respective
properties which could reasonably be expected to result in any judgment against or liability of such Borrower Party or Subsidiary in excess of $10,000,000 individually or in the aggregate with respect to all Borrower Parties and their Subsidiaries,
or the loss of any certification or license material to the operation of such Borrower Party’s or Subsidiary’s business. None of such litigation disclosed on Schedules 5.1(n), individually or collectively, could reasonably be
expected to have a Materially Adverse Effect. 
 (o) ERISA. Schedule 5.1(o) lists (i) all
ERISA Affiliates and (ii) all Plans, and separately identifies all Title IV Plans (other than Multiemployer Plans), Multiemployer Plans, and Retiree Welfare Plans. Copies of all such listed Plans, together with a copy of the latest IRS/DOL 5500
series form for each Plan, have been delivered to the applicable Administrative Agent. Schedule SB, (Actuarial Information) to the most recent IRS/DOL 5500 series form for each Plan is complete and accurate and fairly presents the funding status of
such Plan, and since the date of such Schedule SB there has been no material adverse change in such funding status. Except with respect to Multiemployer Plans, each Plan intended to be qualified under Code Section 401 has been determined by the
Internal Revenue Service to qualify under Section 401 of the Code, the trusts created thereunder have been determined to be exempt from tax under the provisions of Sections 501 of the Code, and nothing has occurred that would reasonably be
expected to cause the loss of such qualification or tax exempt status. Except any such failure to comply which has not, and could not reasonably be expected to have, a Materially Adverse Effect, each Borrower Party


  
 94 









 
and each ERISA Affiliate and each of their respective Plans are in compliance with ERISA and the Code. No Borrower Party or, to each Borrower Party’s knowledge, any of its ERISA Affiliates
has made any promises of retirement or other benefits to employees, except (i) as set forth in the Plans and (ii) that could reasonably be expected to have a Materially Adverse Effect. No Borrower Party or ERISA Affiliate has incurred any
material liability to the PBGC in connection with any such Plan (other than the payment of premiums that are not past due). No Title IV Plan has any Unfunded Pension Liability. No ERISA Event has occurred, is continuing or is reasonably expected to
occur with respect to any Plan. Except as could not reasonably be expected to have a Materially Adverse Effect, there are no pending, or to the knowledge of any Borrower Party, threatened claims (other than claims for benefits in the normal course),
sanctions, actions or lawsuits, asserted or instituted against any Plan or any Person as fiduciary (as defined in Section 3(21) of ERISA) or sponsor of any Plan. Except as could not reasonably be expected to have a Materially Adverse Effect, no
Plan or trust created thereunder, or party in interest (as defined in Section 3(14) of ERISA), or any fiduciary (as defined in Section 3(21) of ERISA), has engaged in a non exempt “prohibited transaction” (as such term is defined
in Section 406 of ERISA or Section 4975 of the Code) which would subject any Plan of any Borrower Party or any of its ERISA Affiliates, any trust created thereunder, or any such party in interest or fiduciary, or any party dealing with any
such Plan or any such trust to any material penalty or tax on “prohibited transactions” imposed by Section 502 of ERISA or Section 4975 of the Code. 

(p) Intellectual Property; Licenses; Certifications. As of the Agreement Date, except as set forth on Schedule
5.1(p), no Borrower Party or any Subsidiary of a Borrower Party owns any registered patents, trademarks, service marks, copyrights, franchises, licenses and other intellectual property (collectively, “IP Rights”) and has no
pending registration applications with respect to any of the foregoing. No other IP Rights are necessary for the operation of the business of the Borrower Parties and their Subsidiaries, except for such IP Rights, the failure to obtain which could
not reasonably be expected to have a Materially Adverse Effect. No claim has been asserted and is pending by any Person challenging or questioning the use of any IP Rights or the validity or effectiveness of any IP Rights, nor does any Borrower
Party have knowledge of any such claim, and, to the knowledge of the Borrower Parties, the use of any IP Rights by any Borrower Party or any Subsidiary or the granting of a right or license in respect of any IP Rights from any Borrower Party or any
Subsidiary does not infringe on the rights of any Person, except, in each case, for such claims, and such infringements, as could not reasonably be expected to have a Materially Adverse Effect. Except as set forth on Schedule 5.1(p),
(a) none of the IP Rights owned by any of the Borrower Parties is subject to any licensing agreement or similar arrangement and (b) no material licenses or certifications are necessary for the operation of the Borrower Parties’ and
their Subsidiaries’ business, except, in each case, for such agreements and arrangements and such licenses and certifications, the failure to obtain which, could not reasonably be expected to have a Materially Adverse Effect. 

  
 95 









 (q) Compliance with Law. Each Borrower Party and each Subsidiary of a
Borrower Party is in compliance with all Applicable Laws and with all of the provisions of its certificate of incorporation or formation and by-laws or other governing documents except where the failure to be in compliance could not reasonably be
expected to have a Materially Adverse Effect. 
 (r) Accuracy and Completeness of Information. All
written information, reports, other papers and data relating to the Borrower Parties and their Subsidiaries furnished by or at the direction of the Borrower Parties to the Lender Group were, at the time furnished, taken as a whole with all other
such information, reports, other papers and data furnished previously or concurrently, complete and correct in all material respects and such information did not contain any material omission, misstatement or other material inaccuracy which has, or
could reasonably be expected to have, a Materially Adverse Effect. With respect to projections, estimates and forecasts given to the Lender Group, such projections, estimates and forecasts are based on the Borrower Parties’ good faith
assessment of the future of the business at the time made. The Borrower Parties had a reasonable basis for such assessment at the time made. 
 (s) Compliance with Regulations T, U, and X. No Borrower Party or any Subsidiary of a Borrower Party is engaged principally in the business of or has as one of its important activities in the
business of extending credit for the purpose of purchasing or carrying, and no Borrower Party or any Subsidiary of a Borrower Party owns or presently intends to acquire, any “margin security” or “margin stock” as defined in
Regulations T, U and X of the Board of Governors of the Federal Reserve System (herein called “Margin Stock”). None of the proceeds of the Loans will be used, directly or indirectly, for the purpose of purchasing or carrying
any Margin Stock or for the purpose of reducing or retiring any Funded Debt which was originally incurred to purchase or carry Margin Stock or for any other purpose which might constitute this transaction a “purpose credit” within the
meaning of said Regulations T, U and X. None of any Borrower Party, any Subsidiary of a Borrower Party or any bank acting on its behalf has taken or will take any action which would cause this Agreement or any other Loan Documents to violate
Regulation T, U or X or any other regulation of the Board of Governors of the Federal Reserve System or to violate the SEA, in each case as now in effect or as the same may hereafter be in effect. If so requested by any Administrative Agent,
the Borrower Parties and their Subsidiaries will furnish the Administrative Agents with a statement or statements in conformity with the requirements of Federal Reserve Form U-1 referred to in Regulation U of said Board of Governors. Neither
the making of the Loans nor the use of proceeds thereof will violate, or be inconsistent with, the provisions of Regulation T, U or X of said Board of Governors. 

(t) Solvency. As of the Agreement Date and after giving effect to the Transactions contemplated by the Loan
Documents (i) the property of the Borrower Parties, on a consolidated basis, at a fair valuation on a going concern basis, will exceed its debt; (ii) the capital of the Borrower Parties, on a consolidated basis, will not be unreasonably
small to conduct their business; and (iii) the Borrower Parties, on a consolidated basis, will not have incurred debts, or have intended to incur debts, beyond their ability to pay such debts as they mature. For purposes of this
Section 5.1(t), “debt” shall mean any liability on a claim, and “claim” shall mean (A) the right to payment, whether or not such right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured,
unmatured, undisputed, legal, equitable, secured or unsecured, or (B) the right to an equitable remedy for breach of performance if such breach gives rise to a right to payment, whether or not such right to an equitable remedy is reduced to
judgment, fixed, contingent, matured, unmatured, undisputed, secured or unsecured. 

  
 96 









 (u) Insurance. The Borrower Parties and their Subsidiaries have
insurance meeting the requirements of Section 6.5, and such insurance policies are in full force and effect. As of the Agreement Date, all insurance maintained by the Borrower Parties and their Subsidiaries is fully described on
Schedule 5.1(u). 
 (v) Broker’s or Finder’s Commissions. No broker’s or
finder’s fee or commission will be payable with respect to the execution and delivery of this Agreement and the other Loan Documents, and no other similar fees or commissions will be payable by the Borrower Parties for any other services
rendered to the Borrower Parties ancillary to the credit transactions contemplated herein.

than $1,000,000, and the name of the lessor of such real property, is set forth in Schedule 5.1(w)-1. The leases of each Borrower Party and each Subsidiary of a Borrower Party are valid, enforceable and in full force and effect, and, as of
the Agreement Date, have not been modified or amended, except as otherwise set forth in Schedule 5.1(w)-1 or as could not reasonably be expected to have a Materially Adverse Effect. All real property owned by each Borrower Party or a
Subsidiary of a Borrower Party as of the Agreement Date with a value in excess of $5,000,000 is set forth in Schedule 5.1(w)-2. The Administrative Borrower shall provide notice to each Administrative Agent upon the purchase by any Borrower
Party of any real property with a value in excess of $5,000,000 upon the request of the Collateral Agent, the applicable Borrower Party shall deliver a Mortgage with respect to such real property and all other documentation reasonably requested by
the Collateral Agent, including, without limitation, one or more opinions of counsel.

in the aggregate, reasonably be expected to have a Materially Adverse Effect, no Borrower Party or any Subsidiary thereof (A) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other
approval required under any Environmental Law, (B) has received notice of any claim with respect to any Environmental Law or (C) knows of any basis for any liability under any Environmental Law.

Borrower Party or any Subsidiary thereof is undertaking, either individually or together with other potentially responsible parties, any investigation or assessment or remedial or response action relating to any actual or threatened release,
discharge or disposal of Hazardous Materials at any site, location or operation, either voluntarily or pursuant to the order of any Governmental Authority or the requirements of any Environmental Law; and (ii) all Hazardous Materials generated,
used, treated, handled or stored at, or transported to or from, any property currently or formerly owned or operated by any Borrower Party or any Subsidiary thereof have been disposed of in a manner not reasonably expected to result in liability to
any Borrower Party or any Subsidiary thereof. 
 (y) Investment Company Act. No Borrower Party or any
Subsidiary of a Borrower Party is required to register under the provisions of the Investment Company Act of 1940, as amended, and neither the entering into or performance by the Borrower Parties of this Agreement nor the issuance of any Notes
violates any provision of such Act or requires any consent, approval, or authorization of, or registration with, any governmental or public body or authority pursuant to any of the provisions of such Act, in each case, that have not already been
obtained. 
 (z) Patriot Act. Neither any Borrower Party nor any of its Subsidiaries is an

hereunder will be used directly or indirectly to fund any operations in, finance any investments or activities in or make any payments to, a Sanctioned Person or a Sanctioned Country or for any payments to any governmental official or employee,
political party, official of a political party, candidate for political office, or anyone else acting in an official capacity, in order to obtain, retain or direct business or obtain any improper advantage, in violation of the United States Foreign
Corrupt Practices Act of 1977, as amended. 
 Section 5.2 Survival of Representations and Warranties, etc. All
representations and warranties made under this Agreement and the other Loan Documents shall be deemed to be made, and shall be true and correct, at and as of the Agreement Date and at the date of each Loan or issuance of a Letter of Credit hereunder
(except to the extent that such representation or warranty specifically refers to an earlier date, in which case it shall be so true and correct as of such earlier date). All representations and warranties made under this Agreement and the other

this Agreement. 
 ARTICLE 6. 
 GENERAL COVENANTS 
 Until the later of the date the Obligations are repaid
in full or the date the Borrowers no longer have the right to borrow, or have Letters of Credit issued, hereunder (whether or not the conditions to borrowing have been or can be fulfilled), and unless the Majority Lenders shall otherwise give their
prior consent in writing: 
 Section 6.1 Preservation of Existence and Similar Matters. Each Borrower Party will,
and will cause each of its Restricted Subsidiaries to (i) except as expressly permitted by Section 8.7, preserve and maintain its due organization, valid existence and good standing, in each case in its jurisdiction of incorporation
or organization, (ii) qualify and remain qualified and authorized to do business in each jurisdiction in which the character of its properties or the nature of its business requires such qualification or authorization except where the failure
to be so qualified would not reasonably be expected to have a Materially Adverse Effect, and (iii) maintain all Necessary Authorizations except where the failure to maintain such Necessary Authorizations could not reasonably be expected to have
a Materially Adverse Effect. 
 Section 6.2 Compliance with Applicable Law. Each Borrower Party will, and will cause
each of its Restricted Subsidiaries to, comply, in all material respects, with the requirements of all Applicable Law, except in such instances in which such requirement of Applicable Law is being contested in good faith by appropriate proceedings

 99 









 Section 6.3 Maintenance of Properties. Each Borrower Party will, and will cause
each of its Restricted Subsidiaries to, maintain or cause to be maintained in the ordinary course of business in good repair, working order and condition, normal wear and tear and disposal of obsolete equipment excepted, all properties used or
useful in its business (whether owned or held under lease), and from time to time make or cause to be made all needed and appropriate repairs, renewals, replacements, additions, betterments, and improvements thereto, except where the failure to do
so could not reasonably be expected to have a Materially Adverse Effect. 
 Section 6.4 Accounting Methods and Financial
Records. Zayo and its Subsidiaries shall maintain, on a consolidated basis, a system of accounting established and administered in accordance with GAAP and will keep adequate records and books of account in which complete entries will be made in
accordance with such accounting principles consistently applied and reflecting all transactions required to be reflected by such accounting principles. 
 Section 6.5 Insurance. Each Borrower Party will, and will cause each of its Restricted Subsidiaries to, maintain insurance including, but not limited to, property insurance, public liability,
comprehensive general liability with respect to losses and claims in excess of $1,000,000 individually, or $2,000,000 in the aggregate during any policy year, business interruption and fidelity coverage insurance, in such amounts and against such
risks as would be customary for companies in the same industry and of comparable size as the Borrower Parties and their Restricted Subsidiaries from financially sound and reputable insurance companies having and maintaining an A.M. Best rating of
“A minus” or better and being in a size category of VI or larger or otherwise acceptable to each Administrative Agent. In addition to the foregoing, each Borrower Party further agrees to maintain and pay for insurance upon all goods
constituting Collateral wherever located, in storage or in transit in vehicles, vessels or aircraft, including goods evidenced by documents, covering casualty, hazard, public liability and such other risks and in such amounts as would be customary
for companies in the same industry and of comparable size as the Borrower Parties and not less than replacement costs, from financially sound and reputable insurance companies having and maintaining an A.M. Best rating of “A minus” or
better and being in a size category of VI or larger or otherwise acceptable to each Administrative Agent to insure the Lender Group’s interest in such Collateral. All such property insurance policies covering goods that constitute Collateral

cause each of its Restricted Subsidiaries to, pay and discharge all taxes, assessments, and governmental charges or levies imposed upon it or its income or profit or upon any properties belonging to it prior to the date on which penalties attach
thereto, and all lawful claims for labor, materials and supplies which have become due and payable and which by law have or may become a Lien upon any of its Property; except that, no such tax, assessment, charge, levy, or claim need be paid which
is being contested in good faith by appropriate proceedings and for which adequate reserves shall have been set aside on the appropriate books, but only so long as such tax, assessment, charge, levy, or claim does not become a Lien or charge other
than a Permitted Lien. 
 Section 6.7 Visits and Inspections. Each Borrower Party will, and will cause each of its

Section 6.8 Intentionally Omitted. 
 Section 6.9 ERISA. Each Borrower Party shall at all times make, or cause to be made, prompt payment of contributions required to meet the minimum funding standards set forth in ERISA with
respect to each Borrower Party’s and its ERISA Affiliates’ Plans that are subject to such funding requirements; furnish to each Administrative Agent, promptly upon any Administrative Agent’s request therefor, copies of any annual

Agent to perfect or continue the perfection of the Collateral Agent’s (on behalf of, and for the benefit of, the Secured Parties) security interest in the Collateral. Each Borrower Party hereby authorizes the Collateral Agent to file any such

 Section 6.11 Blocked Account Agreements. 

(a) Each deposit account and securities account owned or maintained by the Borrower Parties (other than an Excluded Deposit Account)
shall be maintained at a bank or financial institution which is reasonably acceptable to the Collateral Agent (each such bank, a “Cash Management Bank”). As of the Agreement Date, each deposit account and securities account of the
Borrower Parties, other than Excluded Deposit Accounts with individual balances of less than $1,000,000, are listed on Schedule 6.11 and such schedule designates which accounts are deposit accounts. Except with respect to Excluded Deposit
Accounts or with the prior written consent of the Collateral Agent, each deposit account and securities account maintained by any Borrower Party shall be subject to a control agreement in form and substance satisfactory to each Administrative Agent
and such bank or financial institution (each such account, a “Blocked Account Agreement”). Each such Blocked Account Agreement shall provide, among other things, that from and after the Agreement Date, the relevant Cash Management
Bank, agrees, from and after the receipt of a notice (an “Activation Notice”) from the Collateral Agent (which Activation Notice shall be given by the Collateral Agent at any time at which an Event of Default has occurred and is
continuing), to forward immediately all amounts in each deposit account or securities account, as the case may be to the Collateral Agent per its instructions and to commence the process of daily sweeps from such account to the Collateral Agent.

 (b) In the event that any Borrower Party shall at any time receive any remittances of any of the foregoing directly or shall
receive any other funds representing proceeds of the Collateral, such Borrower Party shall hold the same as trustee for the Collateral Agent, shall segregate such remittances from its other assets, and shall promptly deposit the same into a Blocked
Account. All cash, cash equivalents, checks, notes, drafts or similar items of payment received by any Borrower Party shall be deposited into a Blocked Account promptly upon receipt thereof by such Borrower Party. 

Section 6.12 Further Assurances. Upon the request of any Administrative Agent, each Borrower Party will promptly cure, or
cause to be cured, defects in the creation and issuance of any Notes and the execution and delivery of the Loan Documents (including this Agreement) and any Bank Products Documents, resulting from any act or failure to act by any Borrower Party or
any employee or officer thereof. Each Borrower Party at its expense will promptly execute and deliver to each Administrative Agent and the Lenders, or cause to be executed and delivered to each Administrative Agent and the Lenders, all such other
and further documents, agreements, and instruments in compliance with or accomplishment of the covenants and agreements of the Borrower Parties in the Loan Documents (including this Agreement) and the Bank Products Documents, or more fully to effect
the purposes thereof or of any of the Loan Documents or the Bank Products Documents, or to ensure the continued validity, perfection and priority of the Liens in accordance with the terms hereof, all as may be necessary or appropriate in connection
therewith as may be reasonably requested by any Administrative Agent.

agrees to hold each member of the Lender Group harmless from and against any and all losses, liabilities, damages, costs and expenses which may be suffered or incurred by such member of the Lender Group in respect of any claim, suit, action or cause
of action now or hereafter asserted by a broker or any Person acting in a similar capacity arising from or in connection with the execution and delivery of this Agreement or any other Loan Document or Bank Products Document or the consummation of
the transactions contemplated herein or therein. This Section 6.13 shall survive termination of this Agreement. 

Section 6.14 Indemnity. Each Borrower Party will indemnify and hold harmless each Indemnified Person from and against any and
all claims, liabilities, investigations, losses, damages, actions, demands, penalties, judgments, suits, investigations and costs, expenses (including reasonable fees and expenses of experts, agents, consultants and counsel) and disbursements, in
each case, of any kind or nature (whether or not the Indemnified Person is a party to any such action, suit or investigation, and whether such claim, proceeding or action is brought by either any Borrower, any Guarantor, or any third party)
whatsoever which may be imposed on, incurred by, or asserted against an Indemnified Person resulting from any breach or alleged breach by the Borrower Parties of any representation or warranty made hereunder, or otherwise in any way relating to or
arising out of the Revolving Loan Commitment, this Agreement, the other Loan Documents, the Bank Products Documents or any other document contemplated by this Agreement, the making, administration or enforcement of the Loan Documents and the Loans
or any Bank Products Documents, any transaction contemplated hereby or any related matters unless, with respect to any of the above, such Indemnified Person or its officers, directors, employees or agents, is determined by a final non-appealable
judgment of a court of competent jurisdiction to have acted or failed to act with gross negligence or willful misconduct or to have been in material breach of any Loan Document; provided, that in the case of legal fees and expenses, the
Borrower Parties’ indemnification obligations shall be limited to the reasonable and documented out-of-pocket fees, disbursements and other charges of one counsel to all Indemnified Persons taken as a whole in any relevant jurisdiction and, in
the case of any conflict of interest (as reasonably determined by the Indemnified Persons affected by such conflict) one additional counsel in each relevant jurisdiction to each group of affected Indemnified Persons similarly situated taken as a
whole. NO INDEMNIFIED PERSON SHALL BE RESPONSIBLE OR LIABLE TO ANY OTHER PARTY TO ANY LOAN DOCUMENT, ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY BENEFICIARY OF SUCH PERSON OR ANY OTHER PERSON ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR
INDIRECT, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN EXTENDED, SUSPENDED OR TERMINATED UNDER ANY LOAN DOCUMENT OR AS A RESULT OF ANY OTHER TRANSACTION CONTEMPLATED HEREUNDER OR UNDER ANY OTHER
LOAN DOCUMENT. No Indemnified Person shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed to such unintended recipients by such Indemnified Person through telecommunications,
electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby other than for direct or actual damages resulting from the gross negligence or
willful misconduct of such Indemnified Person as determined by a final and nonappealable judgment of a court of competent jurisdiction. This Section 6.14 shall survive termination of this Agreement whether or not any Obligations remain
outstanding.

 ARTICLE 10. 

THE ADMINISTRATIVE AGENTS 
 Section 10.1 Appointment and Authorization . Each member of the Lender Group hereby irrevocably appoints and authorizes, and hereby agrees that it will require any transferee of any of its
interest in this Agreement and the other Loan Documents and its Loans, its portion of the Revolving Loan Commitment and, if applicable, Letter of Credit Commitment irrevocably to appoint and authorize, each Administrative Agent to take such actions
as its agent on its behalf and to exercise such powers hereunder and under the other Loan Documents as are delegated by the terms hereof and thereof, together with such powers as are reasonably incidental thereto. Without limiting the foregoing,
each member of the Lender Group hereby authorizes the applicable Administrative Agent to execute and deliver each Loan Document to which such Administrative Agent is, or is required to be, a party. Neither Administrative Agent nor any of their
directors, officers, employees, or agents shall be liable for any action taken or omitted to be taken by it hereunder or in connection herewith, except for their own gross negligence or willful misconduct as determined by a final non-appealable
order of a court of competent jurisdiction. 
 Section 10.2 Interest Holders . The applicable Administrative Agent
may treat each Lender, or the Person designated in the last notice filed with such Administrative Agent under this Section 10.2, as the holder of all of the interests of such Lender in this Agreement and the other Loan Documents, its
Loans and its portion of the Revolving Loan Commitment until written notice of transfer, signed by such Lender (or the Person designated in the last notice filed with the applicable Administrative Agent) and by the Person designated in such written
notice of transfer, in form and substance satisfactory to such Administrative Agent, shall have been filed with such Administrative Agent. 
 Section 10.3 Consultation with Counsel . Each Administrative Agent may consult with legal counsel selected by it and shall not be liable to any Lender or the Issuing Bank for any action taken
or suffered by it in good faith in reliance on the advice of such counsel. 
 Section 10.4 Documents . The
Administrative Agents shall not be under any duty to examine, inquire into, or pass upon the validity, effectiveness, or genuineness of this Agreement, any other Loan Document, or any instrument, document, or communication furnished pursuant hereto
or in connection herewith, and the Administrative Agents shall be entitled to assume that they are valid, effective, and genuine, have been signed or sent by the proper parties, and are what they purport to be. 

  
 125









 Section 10.5 Administrative Agents and Affiliates . With respect to the
Commitments and Loans, the Administrative Agents shall have the same rights and powers hereunder as any other Lender, and the Administrative Agents and their Affiliates, as the case may be, may accept deposits from, lend money to, and generally
engage in any kind of business with the Borrower Parties or any Affiliates of, or Persons doing business with, the Borrower Parties, as if it were not an Administrative Agent or affiliated with an Administrative Agent and without any obligation to
account therefor. The Lenders and the Issuing Bank acknowledge that the Administrative Agents and their Affiliates have other lending and investment relationships with the Borrower Parties and their Affiliates and in the future may enter into
additional such relationships. 
 Section 10.6 Responsibility of the Administrative Agents . Notwithstanding any
provision to the contrary contained elsewhere in this Agreement or in any other Loan Document, the Administrative Agents shall not have any duties or responsibilities, except those expressly set forth herein, nor shall the Administrative Agents have
or be deemed to have any fiduciary relationship with any other member of the Lender Group, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agents. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Agreement with reference to the Administrative Agents is not intended to connote any
fiduciary or other implied (or express) obligations arising under agency doctrine of any Applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between
independent contracting parties. The Administrative Agents shall be entitled to assume that no Default exists unless it has actual knowledge, or has been notified by any Borrower Party, of such fact, or has been notified by a Lender that such Lender
considers that a Default exists, and such Lender shall specify in detail the nature thereof in writing. The Administrative Agents shall provide each Lender with copies of such documents received from any Borrower Party as such Lender may reasonably
request. 
 Section 10.7 Action by Administrative Agents. 

(a) The Administrative Agents shall be entitled to use their discretion with respect to exercising or refraining from exercising any
rights which may be vested in it by, and with respect to taking or refraining from taking any action or actions which it may be able to take under or in respect of, this Agreement, unless the Administrative Agents shall have been instructed by the
Majority Lenders to exercise or refrain from exercising such rights or to take or refrain from taking such action. The Administrative Agents shall incur no liability under or in respect of this Agreement with respect to anything which it may do or
refrain from doing in the reasonable exercise of its judgment or which may seem to it to be necessary or desirable in the circumstances. 
 (b) The Administrative Agents shall not be liable to the Lenders and the Issuing Bank, or any of them, in acting or refraining from acting under this Agreement or any other Loan Document in accordance
with the instructions of the Majority Lenders (or all Lenders if expressly required by Section 11.12), and any action taken or failure to act pursuant to such instructions shall be binding on all Lenders and the Issuing Bank. 


  
 126









 Section 10.8 Notice of Default . In the event that any member of the Lender
Group shall acquire actual knowledge, or shall have been notified in writing, of any Default, such member of the Lender Group shall promptly notify the other members of the Lender Group, and the applicable Administrative Agent shall take such action
and assert such rights under this Agreement as the Majority Lenders shall request in writing, and the applicable Administrative Agent shall not be subject to any liability by reason of its acting pursuant to any such request. If the Majority Lenders
shall fail to request the applicable Administrative Agent to take action or to assert rights under this Agreement in respect of any Default after their receipt of the notice of any Default from a member of the Lender Group, or shall request
inconsistent action with respect to such Default, the applicable Administrative Agent may, but shall not be required to, take such action and assert such rights (other than rights under Article 9) as it deems in its discretion to be advisable
for the protection of the Lender Group, except that, if the Majority Lenders have instructed the applicable Administrative Agent not to take such action or assert such right, in no event shall the applicable Administrative Agent act contrary to such
instructions. 
 Section 10.9 Responsibility Disclaimed . The Administrative Agents shall not be under any liability
or responsibility whatsoever as an Administrative Agent: 
 (a) to any Borrower Party or any other Person or
entity as a consequence of any failure or delay in performance by or any breach by, any member of the Lender Group of any of its obligations under this Agreement; 

(b) to any Lender Group, or any of them, as a consequence of any failure or delay in performance by, or any breach by, any
Borrower Party or any other obligor of any of its obligations under this Agreement or any other Loan Document; or 
 (c) to any Lender Group, or any of them, for any statements, representations, or warranties in this Agreement, or any other document contemplated by this Agreement or any information provided pursuant to
this Agreement, any other Loan Document, or any other document contemplated by this Agreement, or for the validity, effectiveness, enforceability, or sufficiency of this Agreement, any other Loan Document, or any other document contemplated by this
Agreement. 
 Section 10.10 Indemnification . The Lenders agree to indemnify (to the extent not reimbursed by the
Borrowers) and hold harmless each Administrative Agent and each of their Affiliates, employees, representatives, officers and directors (each an “Administrative Agent Indemnified Person”) pro rata in accordance with their Commitment
Ratios from and against any and all claims, liabilities, investigations, losses, damages, actions, demands, penalties, judgments, suits, investigations, costs, expenses (including fees and expenses of experts, agents, consultants and counsel) and
disbursements, in each case, of any kind or nature (whether or not an Administrative Agent Indemnified Person is a party to any such action, suit or investigation) whatsoever which may be imposed on, incurred by, or asserted against an
Administrative Agent Indemnified Person resulting from any breach or alleged breach by the Borrower Parties, or any of them, of any representation or warranty made hereunder, or otherwise in any way relating to or arising out of the Commitments, the
Loans, the Letters of Credit, this Agreement, the other Loan Documents or any other document contemplated by this Agreement or any action taken or omitted by the Administrative Agents under this Agreement, any other Loan Document, or any other
document contemplated by this Agreement (other than Bank Products Documents), the making, administration or enforcement of the Loan Documents and the Loans or any transaction contemplated hereby or any related matters unless, with respect to any of
the above, such Administrative Agent Indemnified Person is determined by a final non-appealable judgment of a court of competent jurisdiction to have acted or failed to act with gross negligence or willful misconduct. This Section 10.10
is for the benefit of each Administrative Agent Indemnified Person and shall not in any way limit the obligations of the Borrower Parties under Section 6.14. The provisions of this Section 10.10 shall survive the termination
of this Agreement. 

  
 127









 Section 10.11 Credit Decision . Each member of the Lender Group represents and
warrants to each other member of the Lender Group and the Administrative Agents that: 
 (a) In making its
decision to enter into this Agreement and to make its Loans it has independently taken whatever steps it considers necessary to evaluate the financial condition and affairs of the Borrower Parties and that it has made an independent credit judgment,
and that it has not relied upon information provided by the Administrative Agents or any of their Affiliates; 

(b) So long as any portion of the Obligations remains outstanding, it will continue to make its own independent evaluation
of the financial condition and affairs of the Borrower Parties; and 
 (c) Except for notices, reports and other
documents expressly herein required to be furnished to the Lenders by the Administrative Agents, the Administrative Agents shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business,
prospects, operations, property, financial and other condition or creditworthiness of the Borrower Parties which may come into the possession of any of the Administrative Agents or any Affiliates of the Administrative Agents. 

Section 10.12 Successor Administrative Agents . Subject to the appointment and acceptance of a successor Administrative
Agent, as provided below, the applicable Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Administrative Borrower. Upon any such resignation, the Revolving Facility Majority Lenders or Term Facility
Majority Lenders, as applicable, shall have the right to appoint a successor Term Facility Administrative Agent or Revolving Facility Administrative Agent, as applicable (with the consent of the Administrative Borrower if no Event of Default then
exists). If no successor Administrative Agent shall have been so appointed pursuant to this Section 10.12, and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent’s giving of
notice of resignation (or such earlier day as shall be agreed by the Term Facility Majority Lenders or Revolving Facility Majority Lenders, as applicable) (the “Resignation Effective Date”), then the retiring Administrative Agent
may, on behalf of the Lenders, appoint a successor Term Facility Administrative Agent or Revolving Facility Administrative Agent, as applicable, which shall be any Lender or a Person organized under the laws of the US, a State or any political
subdivision thereof which has combined capital and reserves in excess of $250,000,000; provided that if the applicable Administrative Agent shall notify the Borrowers and the Lenders that no qualifying Person has accepted such appointment,
then, whether or not a successor has been appointed, such resignation shall nonetheless become effective in accordance with such notice on the Resignation Effective Date. Upon the acceptance of any appointment as an Administrative Agent hereunder by
a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges, duties, and obligations of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations hereunder. After any retiring Administrative Agent’s resignation hereunder as an Administrative Agent, the provisions of this Article 10 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting an Administrative Agent. 

  
 128









 Section 10.13 Administrative Agents May File Proofs of Claim . Each
Administrative Agent may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of such Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements
and advances of such Administrative Agent, its agents, financial advisors and counsel), the Lenders and the Issuing Bank allowed in any judicial proceedings relative to any Borrower Party, or any of their respective creditors or property, and shall

such Administrative Agent for the reasonable compensation, expenses, disbursements and advances of such Administrative Agent, its agents, financial advisors and counsel, and any other amounts due such Administrative Agent under
Section 11.2. Nothing contained in this Agreement or the Loan Documents shall be deemed to authorize any Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or the Issuing Bank any plan of
reorganization, arrangement, adjustment or composition affecting this Agreement, any Notes, the Letters of Credit or the rights of any holder thereof, or to authorize any Administrative Agent to vote in respect of the claim of any Lender or the
Issuing Bank in any such proceeding.

Products Documents and all interest, fees and expenses hereunder constitute one Funded Debt, secured by all of the Collateral. The Collateral Agent hereby appoints each Lender and the Issuing Bank as its agent (and each Lender and the Issuing Bank

delay by the Lender Group, or any of them, or the Majority Lenders in exercising any right shall operate as a waiver of such right. The Lender Group expressly reserves the right to require strict compliance with the terms of this Agreement in
connection with any funding of a request for an Loan. In the event the Lenders decide to fund a request for an Loan at a time when the Borrowers are not in strict compliance with the terms of this Agreement, such decision by the Lenders shall not be
deemed to constitute an undertaking by the Lenders to fund any further requests for Loans or preclude the Lenders from exercising any rights available to the Lenders under the Loan Documents or at law or equity. Any waiver or indulgence granted by
the Lenders or by the Majority Lenders shall not constitute a modification of this Agreement, except to the extent expressly provided in such waiver or indulgence, or constitute a course of dealing by the Lenders at variance with the terms of the
Agreement such as to require further notice by the Lenders of the Lenders’ intent to require strict adherence to the terms of the Agreement in the future. Any such actions shall not in any way affect the ability of the Lenders, in their
discretion, to exercise any rights available to them under this Agreement or under any other agreement, whether or not the Lenders are party, relating to the Borrowers. 

  
 133









 Section 11.4 Set-Off. In addition to any rights now or hereafter granted under
Applicable Law and not by way of limitation of any such rights, except to the extent limited by Applicable Law, at any time that an Event of Default exists, each member of the Lender Group and each subsequent holder of the Obligations is hereby
authorized by the Borrower Parties at any time or from time to time, without notice to the Borrower Parties 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, time or demand, including, but not limited to, Funded Debt evidenced by certificates of deposit, in each case whether matured or unmatured, but not including any amounts held by any member of the Lender Group or any of its Affiliates in
any escrow account) and any other Funded Debt at any time held or owing by any member of the Lender Group or any such holder to or for the credit or the account of any Borrower Party, against and on account of the obligations and liabilities of the
Borrower Parties, to any member of the Lender Group or any such holder under this Agreement, any Notes, any other Loan Document and any Bank Products Documents, including, but not limited to, all claims of any nature or description arising out of or
connected with this Agreement, any Notes, any other Loan Document or any Bank Products Document, irrespective of whether or not (a) the Lender Group shall have made any demand hereunder or (b) the Lender Group shall have declared the
principal of and interest on the Loans and any Notes and other amounts due hereunder to be due and payable as permitted by Section 9.2 and although said obligations and liabilities, or any of them, shall be contingent or unmatured. Any
sums obtained by any member of the Lender Group or by any subsequent holder of the Obligations shall be subject to the application of payments provisions of Article 2. 
 Section 11.5 Assignment. 
 (a) The provisions of this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that no Borrower Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior
written consent of each Lender (and any attempted assignment or transfer by any Borrower Party without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than
the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Indemnified Parties) any legal or equitable right, remedy or claim under or by reason of this Agreement.
Notwithstanding anything else in this Section 11.5, no assignments, participations or other transfers of rights under this Agreement shall be permitted to any Person that is a competitor, or an Affiliate of a competitor, or any Borrower
Party or any of its Subsidiaries; provided, however, that in connection with any assignment, participation or other transfer of rights to an entity other than any entity previously designated in writing by the Administrative Borrower (and made
available to the Lenders) as a competitor or an Affiliate of a competitor, a Lender may conclusively rely upon a representation by such entity that it is not a competitor or an Affiliate of a Competitor. 

  
 134









 (b) Any Lender (and any Lender that is an Issuing Bank) may assign to one or more Eligible
Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its portion of the Revolving Loan Commitment (which assignment shall automatically include an assignment of the Letter of Credit Commitment
which is a subset of the Revolving Loan Commitment) and the Loans at the time owing to it and excluding rights and obligations with respect to Bank Products Documents); provided that (i) except in the case of an assignment of the entire
remaining amount of the assigning Lender’s portion of the Revolving Loan Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the
aggregate amount of the portion of the Revolving Loan Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the applicable
Administrative Agent) shall not be less than $1,000,000, unless each of the applicable Administrative Agent and, so long as no Event of Default under Section 9.16(b), (g) or (h) has occurred and is continuing, the Administrative
Borrower otherwise consents (each such consent not to be unreasonably withheld), and (ii) the parties to each assignment shall execute and deliver to the applicable Administrative Agent an Assignment and Acceptance, together with (in the case
of assignments under the Revolving Loan Facility) a processing and recordation fee of $3,500 (unless such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund), and the Eligible Assignee, if it shall not be a Lender, shall deliver
to the applicable Administrative Agent an Administrative Questionnaire. Subject to acceptance and recording thereof by the applicable Administrative Agent pursuant to Section 11.5(c), from and after the effective date specified in each
Assignment and Acceptance, the Eligible Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s
rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.8(b), 2.9, 6.16, 12.3 and 12.5). Any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with
paragraph (d) of this Section 11.5. 
 (c) The applicable Administrative Agent, acting solely for this purpose
as an agent of the Borrowers, shall maintain at the applicable Administrative Agents’ Office a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the portion
of the Revolving Loan Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error,
and the Borrowers, the applicable Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary; provided, that failure to make any such recordation, or any error in such recordation, shall not affect the Commitment of any Lender. The Register shall be available for inspection by the Borrowers and any Lender, at any reasonable
time and from time to time upon reasonable prior notice. 

  
 135









 (d) Any Lender may, without the consent of, or notice to, the Borrowers or the
Administrative Agents, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its portion
of the Revolving Loan Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) the Borrowers and the Lender Group shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this
Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in Section 11.12(a)(i) that affects such
Participant. Subject to paragraph (e) of this Section, the Borrowers agree that each Participant shall be entitled to the benefits of Sections 2.8(b), 2.9, 6.16 and 12.3 to the same extent as if it were a Lender
and had acquired its interest by assignment pursuant to Section 11.5(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.4 as though it were a Lender, provided such
Participant agrees to be subject to Section 2.10 as though it were a Lender. 
 (e) A Participant shall not be
entitled to receive any greater payment under Section 2.8(b) or Section 12.3 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the
participation to such Participant is made with the Administrative Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.8(b) unless the
Administrative Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 2.8(b) as though it were a Lender. 

(f) Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a
register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant
Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any
commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in
registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the
Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agents (each in its capacity as an Administrative Agent) shall have
no responsibility for maintaining a Participant Register. 

  
 136









 (g) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement to secure obligations of such Lender, including without limitation (i) any pledge or assignment to secure obligations to a Federal Reserve Bank or any central bank having jurisdiction over such Lender and
(ii) in the case of any Lender that is a Fund, any pledge or assignment of all or any portion of such Lender’s rights under this Agreement to any holders of obligations owed, or securities issued, by such Lender as security for such
obligations or securities, or to any trustee for, or any other representative of, such holders, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security
interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 
 (h) Notwithstanding anything in this Agreement (including but not limited to Sections 2.6 and 2.10 (which provisions shall not be applicable to this Section 11.5(h)) or in any
other Loan Document to the contrary, any Borrower Party may purchase the outstanding Term Loans on the following basis: 
 (i)
Any Borrower Party shall have the right to purchase Term Loans at a discount to par pursuant to an Offer of Specified Discount Purchase, Solicitation of Discount Range Sale Offers or Solicitation of Discounted Sale Offers (any such purchase, a
“Discounted Loan Purchase”), in each case made in accordance with this Section 11.5(h); provided that, no Borrower Party shall initiate any action under this Section 11.5(h) in order to make a Discounted Loan
Purchase unless (I) at least ten (10) Business Days shall have passed since the consummation of the most recent Discounted Loan Purchase as a result of a purchase made by a Borrower Party on the applicable Discounted Purchase Effective
Date; or (II) at least three (3) Business Days shall have passed since the date the Borrower Party was notified that no Lender was willing to sell any Term Loan at the Specified Discount, within the Discount Range or at any discount to par
value, as applicable, or in the case of Solicitation of Discounted Sale Offers, the date of any Borrower Party’s election not to accept any Solicited Discounted Sale Offers; provided further that, none of the Borrower Parties shall
initiate any process to effect a Discounted Loan Purchase that shall coincide with any prepayment of Term Loans pursuant to Section 2.5(a) or (b), and any scheduled repayment of Term Loans pursuant to Section 2.6.

 (ii) (1) Subject to the proviso to subsection (i) above, any Borrower Party may from time to time offer to make a
Discounted Loan Purchase by providing the Auction Agent notice in the form of a Specified Discount Purchase Notice; provided that (I) any such offer shall be made available, at the sole discretion of the Borrower Party, to (x) each
Lender and/or (y) each Lender with respect to any Tranche of Term Loans on an individual Tranche basis, (II) any such offer shall specify the aggregate principal amount offered to be purchased (the “Specified Discount Purchase
Amount”) with respect to each applicable tranche, the tranche or tranches of Term Loans subject to such offer and the specific percentage discount to par (the “Specified Discount”) of such Term Loans to be purchased (it
being understood that different Specified Discounts and/or Specified Discount Purchase Amounts may be offered with respect to different Tranches of Term Loans and, in such event, each such offer will be treated as a separate offer pursuant to the
terms of this Section), (III) the Specified Discount Purchase Amount shall be in an aggregate amount not less than $5,000,000 and whole increments of $500,000 in excess thereof and (IV) each such offer shall remain outstanding through the Specified
Discount Purchase Response Date. The Auction Agent will promptly provide each Lender holding Term Loans in respect of which an Offer of Specified Discount Purchase is made with a copy of such Specified Discount Purchase Notice and a form of the
Specified Discount Purchase Response to be completed and returned by each such Lender to the Auction Agent (or its delegate) by no later than 5:00 p.m., New York time, on the third Business Day after the date of delivery of such notice to such
Lenders (which date may be extended for a period not exceeding three Business Days upon notice by the applicable Borrower Party to the Auction Agent (and the Auction Agent shall promptly notify the applicable Lenders)) (the “Specified
Discount Purchase Response Date”). 

  
 137









 (2) Each Lender receiving such offer shall notify the Auction Agent (or its delegate) by
the Specified Discount Purchase Response Date whether or not it agrees to sell any of its applicable then outstanding Term Loans at the Specified Discount and, if so (such accepting Lender, a “Discount Purchase Accepting Lender”),
the amount and the tranches of such Lender’s Term Loans to be sold at such offered discount. Each acceptance of a Discounted Loan Purchase by a Discount Purchase Accepting Lender shall be irrevocable. Any Lender whose Specified Discount
Purchase Response is not received by the Auction Agent by the Specified Discount Purchase Response Date shall be deemed to have declined to accept the applicable Offer of Specified Discount Purchase. 

(3) If there is at least one Discount Purchase Accepting Lender, the relevant Borrower Party will purchase the outstanding Term Loans of
each Discount Purchase Accepting Lender on the Discounted Purchase Effective Date in accordance with the respective outstanding amount and tranches of Term Loans specified in such Lender’s Specified Discount Purchase Response given pursuant to
subsection (2) above; provided that, if the aggregate principal amount of Term Loans tendered for sale by all Discount Purchase Accepting Lenders exceeds the Specified Discount Purchase Amount, such purchase shall be made pro rata among the
Discount Purchase Accepting Lenders in accordance with the respective principal amounts tendered to be sold by each such Discount Purchase Accepting Lender and the Auction Agent (in consultation with such Borrower Party and subject to rounding
requirements of the Auction Agent made in its reasonable discretion) will calculate such proration (the “Specified Discount Proration”). The Auction Agent shall promptly, and in any case within three (3) Business Days following
the Specified Discount Purchase Response Date, notify (I) the relevant Borrower Party of the respective Lenders’ responses to such offer, the Discounted Purchase Effective Date and the aggregate principal amount of the Discounted Loan
Purchase and the Tranches to be prepaid, (II) each Lender of the Discounted Purchase Effective Date, and the aggregate principal amount and the Tranches of Term Loans to be prepaid at the Specified Discount on such date and (III) each Discount
Purchase Accepting Lender of the Specified Discount Proration, if any, and confirmation of the principal amount, Tranche and Type of Term Loans of such Lender to be prepaid at the Specified Discount on such date. Each determination by the Auction
Agent of the amounts stated in the foregoing notices to the Borrower Party and such Lenders shall be conclusive and binding for all purposes absent manifest error. The payment amount specified in such notice to the Borrower Party shall be due and
payable by such Borrower Party on the Discounted Purchase Effective Date in accordance with subsection (iv) below (subject to subsection (x) below). 

  
 138









 (iii) (1) Subject to the proviso to subsection (i) above, any Borrower Party may from
time to time solicit Discount Range Sale Offers by providing the Auction Agent with notice in the form of a Discount Range Solicitation Notice; provided that (I) any such solicitation shall be extended, at the sole discretion of such Borrower
Party, to (x) each Lender and/or (y) each Lender with respect to any Tranche of Term Loans on an individual Tranche basis, (II) any such notice shall specify the maximum aggregate principal amount of the relevant Term Loans (the
“Discount Range Solicitation Amount”), the Tranche or Tranches of Term Loans subject to such offer and the maximum and minimum percentage discounts to par (the “Discount Range”) of the principal amount of such Term
Loans with respect to each relevant Tranche or Tranches of Term Loans willing to be purchased by such Borrower Party (it being understood that different Discount Ranges and/or Discount Range Solicitation Amounts may be offered with respect to
different Tranches of Term Loans and, in such event, each such offer will be treated as separate offer pursuant to the terms of this Section), (III) the Discount Range Solicitation Amount shall be in an aggregate amount not less than $5,000,000 and
whole increments of $500,000 in excess thereof and (IV) each such solicitation by the Borrower shall remain outstanding through the Discount Range Sale Response Date. The Auction Agent will promptly provide each Appropriate Lender with a copy of
such Discount Range Solicitation Notice and a form of the Discount Range Sale Offer to be submitted by a responding Lender to the Auction Agent (or its delegate) by no later than 5:00 p.m., New York time, on the third Business Day after the date of
delivery of such notice to such Lenders (which date may be extended for a period not exceeding three Business Days upon notice by the Borrower Party to the Auction Agent (and the Auction Agent shall promptly notify the applicable Lenders)) (the
“Discount Range Sale Response Date”). Each Lender’s Discount Range Sale Offer shall be irrevocable until the Discounted Purchase Effective Date (at which time such Discount Range Sale Offer shall be deemed to have been
automatically revoked by such Lender as to any of such Lender’s Term Loans not purchased by such Borrower Party on or prior to such date) and shall specify one or more (but no more than three for any Lender) discounts to par within the Discount
Range (the “Submitted Discount”) at which such Lender is willing to sell any or all of its then outstanding Term Loans of the applicable Tranche or Tranches and the maximum aggregate principal amount and tranches of such
Lender’s Term Loans (the “Submitted Amount”) such Lender is willing to sell at the Submitted Discount. Any Lender whose Discount Range Sale Offer is not received by the Auction Agent by the Discount Range Sale Response Date
shall be deemed to have declined to accept a Discounted Loan Purchase of any of its Term Loans at any discount to their par value within the Discount Range. 
 (2) The Auction Agent shall review all Discount Range Sale Offers received on or before the applicable Discount Range Sale Response Date and shall determine (in consultation with such Borrower Party and
subject to rounding requirements of the Auction Agent made in its sole reasonable discretion) the Applicable Discount and Term Loans to be purchased at such Applicable Discount in accordance with this subsection (iii). The relevant Borrower Party
agrees to accept on the Discount Range Sale Response Date all Discount Range Sale Offers received by Auction Agent within the Discount Range by the Discount Range Sale Response Date, in the order from the Submitted Discount that is the largest
discount to par to the Submitted Discount that is the smallest discount to par, up to and including the Submitted Discount that is the smallest discount to par within the Discount Range (such Submitted Discount that is the smallest discount to par
within the Discount Range being referred to as the “Applicable Discount”) which yields a Discounted Loan Purchase in an aggregate principal amount equal to the lower of (I) the Discount Range Solicitation Amount and (II) the
sum of all Submitted Amounts. Each Lender that has submitted a Discount Range Sale Offer to sell Term Loans at a discount to par that is larger than or equal to the Applicable Discount shall be deemed to have offered to sell Term Loans equal to its
Submitted Amount (subject to any required proration pursuant to the following subsection (3)) to such Borrower Party its at the Applicable Discount (each such Lender, a “Participating Lender”), which offer shall be irrevocable
until the Discounted Purchase Effective Date (at which time such Discount Range Sale Offer shall be deemed to have been automatically revoked by such Lender as to any of such Lender’s Term Loans not purchased by such Borrower Party on or prior
to such date). 

  
 139









 (3) If there is at least one Participating Lender, the relevant Borrower Party will accept
such Participating Lender’s Discount Range Sale Offer and purchase the respective outstanding Term Loans of each Participating Lender on the Discounted Purchase Effective Date in the aggregate principal amount and of the Tranches specified in
such Lender’s Discount Range Sale Offer at the Applicable Discount; provided that if the Submitted Amount by all Participating Lenders offered at a discount to par greater than the Applicable Discount exceeds the Discount Range Solicitation
Amount, the purchase of the principal amount of the relevant Term Loans for those Participating Lenders whose Submitted Discount is a discount to par greater than or equal to the Applicable Discount (the “Identified Participating
Lenders”) shall be made pro rata among the Identified Participating Lenders in accordance with the Submitted Amount of each such Identified Participating Lender and the Auction Agent (in consultation with such Borrower Party and subject to
rounding requirements of the Auction Agent made in its sole reasonable discretion) will calculate such proration (the “Discount Range Proration”). The Auction Agent shall promptly, and in any case within five (5) Business Days
following the Discount Range Sale Response Date, notify (I) the relevant Borrower Party of the respective Lenders’ responses to such solicitation, the Discounted Purchase Effective Date, the Applicable Discount, and the aggregate principal
amount of the Discounted Loan Purchase and the tranches to be prepaid, (II) each Lender of the Discounted Purchase Effective Date, the Applicable Discount, and the aggregate principal amount and tranches of Term Loans to be prepaid at the Applicable
Discount on such date, (III) each Participating Lender of the aggregate principal amount and tranches of such Lender to be prepaid at the Applicable Discount on such date, and (IV) if applicable, each Identified Participating Lender of the Discount
Range Proration. Each determination by the Auction Agent of the amounts stated in the foregoing notices to the relevant Borrower Party and Lenders shall be conclusive and binding for all purposes absent manifest error. The payment amount specified
in such notice to the Borrower Party shall be due and payable by such Borrower Party on the Discounted Purchase Effective Date in accordance with subsection (iv) below (subject to subsection (x) below). 

(iv) (1) Subject to the proviso to subsection (i) above, any Borrower Party may from time to time solicit Solicited Discounted Sale
Offers by providing the Auction Agent with notice in the form of a Solicited Discounted Solicitation Notice; provided that (I) any such solicitation shall be extended, at the sole discretion of such Borrower Party, to (x) each
Lender and/or (y) each Lender with respect to any Tranche of Term Loans on an individual Tranche basis, (II) any such notice shall specify the maximum aggregate amount of the Term Loans (the “Solicited Discounted Solicitation
Amount”) and the tranche or tranches of Term Loans the Borrower is willing to purchase at a discount (it being understood that different Solicited Discounted Solicitation Amounts may be offered with respect to different Tranches of Term
Loans and, in such event, each such offer will be treated as separate offer pursuant to the terms of this Section), (III) the Solicited Discounted Solicitation Amount shall be in an aggregate amount not less than $5,000,000 and whole increments of
$500,000 in excess thereof and (IV) each such solicitation by the Borrower shall remain outstanding through the Solicited Discounted Sale Response Date. The Auction Agent will promptly provide each Appropriate Lender with a copy of such Solicited
Discounted Solicitation Notice and a form of the Solicited Discounted Sale Offer to be submitted by a responding Lender to the Auction Agent (or its delegate) by no later than 5:00 p.m., New York time on the third Business Day after the date of
delivery of such notice to such Lenders (which date may be extended for a period not exceeding three Business Days upon notice by the Borrower Party to the Auction Agent (and the Auction Agent shall promptly notify the applicable Lenders)) (the
“Solicited Discounted Sale Response Date”). Each Lender’s Solicited Discounted Sale Offer shall (x) be irrevocable, (y) remain outstanding until the Acceptance Date, and (z) specify both one or more (but no more
than three) discounts to par (the “Offered Discount”) at which such Lender is willing to sell its then outstanding Loan and the maximum aggregate principal amount and Tranches of such Term Loans (the “Offered
Amount”) such Lender is willing to sell the Offered Discount. Any Lender whose Solicited Discounted Sale Offer is not received by the Auction Agent by the Solicited Discounted Sale Response Date shall be deemed to have declined to sell any
of any of its Term Loans at any discount. 

  
 140









 (2) The Auction Agent shall promptly provide the relevant Borrower Party with a copy of all
Solicited Discounted Sale Offers received on or before the Solicited Discounted Sale Response Date. Such Borrower Party shall review all such Solicited Discounted Sale Offers and select the largest of the Offered Discounts specified by the relevant
responding Lenders in the Solicited Discounted Sale Offers that is acceptable to the Borrower Party in its sole discretion (the “Acceptable Discount”), if any. If the Borrower Party elects, in its sole discretion, to accept any
Offered Discount as the Acceptable Discount, in no event later than by the third Business Day after the date of receipt by such Borrower Party from the Auction Agent of a copy of all Solicited Discounted Sale Offers pursuant to the first sentence of
this subsection (2) (the “Acceptance Date”), the Borrower Party may submit an Acceptance and Purchase Notice to the Auction Agent setting forth the Acceptable Discount. If the Auction Agent shall fail to receive an Acceptance
and Purchase Notice from the Borrower Party by the Acceptance Date, such Borrower Party shall be deemed to have rejected all Solicited Discounted Sale Offers. 
 (3) Based upon the Acceptable Discount and the Solicited Discounted Sale Offers received by Auction Agent by the Solicited Discounted Sale Response Date, within three (3) Business Days after receipt
of an Acceptance and Purchase Notice (the “Discounted Purchase Determination Date”), the Auction Agent will determine (in consultation with such Borrower Party and subject to rounding requirements of the Auction Agent made in its
sole reasonable discretion) the aggregate principal amount and the Tranches of Term Loans (the “Acceptable Purchase Amount”) to be purchased by the relevant Borrower Party at the Acceptable Discount in accordance with this
Section 11.5(h)(iv)(3). If the Borrower Party elects to accept any Acceptable Discount, then the Borrower Party agrees to accept all Solicited Discounted Sale Offers received by the Auction Agent by the Solicited Discounted Sale Response
Date, in the order from largest Offered Discount to smallest Offered Discount, up to and including the Acceptable Discount. Each Lender that has submitted a Solicited Discounted Sale Offer with an Offered Discount that is greater than or equal to
the Acceptable Discount shall be deemed to have irrevocably agreed to sell Term Loans equal to its Offered Amount (subject to any required pro-rata reduction pursuant to the following sentence) at the Acceptable Discount (each such Lender, a
“Qualifying Lender”). The Borrower Party may purchase outstanding Term Loans pursuant to this subsection (iv) from each Qualifying Lender in the aggregate principal amount and of the tranches specified in such Lender’s
Solicited Discounted Sale Offer at the Acceptable Discount; provided that if the aggregate Offered Amount by all Qualifying Lenders whose Offered Discount is greater than or equal to the Acceptable Discount exceeds the Solicited Discounted
Solicitation Amount, purchases of the principal amount of the Term Loans for those Qualifying Lenders whose Offered Discount is greater than or equal to the Acceptable Discount (the “Identified Qualifying Lenders”) shall be made pro
rata among the Identified Qualifying Lenders in accordance with the Offered Amount of each such Identified Qualifying Lender and the Auction Agent (in consultation with such Borrower Party and subject to rounding requirements of the Auction Agent
made in its sole reasonable discretion) will calculate such proration (the “Solicited Discount Proration”). On or prior to the Discounted Purchase Determination Date, the Auction Agent shall promptly notify (I) the relevant
Borrower Party of the Discounted Purchase Effective Date and Acceptable Purchase Amount comprising the Discounted Loan Purchase and the tranches to be purchased, (II) each Lender of the Discounted Purchase Effective Date, the Acceptable Discount,
and the Acceptable Purchase Amount of all Term Loans and the Tranches to be purchased at the Applicable Discount on such date, (III) each Qualifying Lender of the aggregate principal amount and the tranches of such Lender to be purchased at the
Acceptable Discount on such date, and (IV) if applicable, each Identified Qualifying Lender of the Solicited Discount Proration. Each determination by the Auction Agent of the amounts stated in the foregoing notices to such Borrower Party and
Lenders shall be conclusive and binding for all purposes absent manifest error. The payment amount specified in such notice to such Borrower Party shall be due and payable by such Borrower Party on the Discounted Purchase Effective Date in
accordance with subsection (iv) below (subject to subsection (x) below). 

  
 141









 (v) In connection with any Discounted Loan Purchase, the Borrower Parties and the Lenders
acknowledge and agree that the Auction Agent may require as a condition to any Discounted Loan Purchase, the payment of customary fees and expenses from a Borrower Party in connection therewith. 

(vi) If any Loan is purchased in accordance with subsections (ii) through (iv) above, a Borrower Party shall purchase such
Term Loans on the Discounted Purchase Effective Date without premium or penalty. The relevant Borrower Party shall make payment in respect of its purchase of such Term Loans to the applicable Administrative Agent, for the account of the Discount
Purchase Accepting Lenders, Participating Lenders, or Qualifying Lenders, as applicable, at the applicable Administrative Agent’s Office in immediately available funds not later than 1:00 p.m. (New York time) on the Discounted Purchase
Effective Date and all such purchases shall be applied to the remaining principal installments of the relevant tranche of Term Loans on a pro-rata basis across such installments. The Term Loans so purchased shall be accompanied by all accrued and
unpaid interest on the par principal amount so prepaid up to, but not including, the Discounted Purchase Effective Date. The consideration for each purchase of outstanding Term Loans pursuant to this Section 11.5(h) shall be paid to the
Discount Purchase Accepting Lenders, Participating Lenders, or Qualifying Lenders, as applicable, and shall be applied to the relevant Term Loans of such Lenders in accordance with their respective Commitment Ratios. The aggregate principal amount
of the tranches and installments of the relevant Term Loans outstanding shall be deemed reduced by the full par value of the aggregate principal amount of the tranches of Term Loans prepaid on the Discounted Purchase Effective Date in any Discounted
Loan Purchase. 

  
 142









 (vii) To the extent not expressly provided for herein, each Discounted Loan Purchase shall
be consummated pursuant to procedures consistent with the provisions in this Section 11.5(h) or as otherwise established by the Auction Agent acting in its reasonable discretion and as reasonably agreed by the Borrower. 

(viii) Notwithstanding anything in any Loan Document to the contrary, for purposes of this Section 11.5(h), to the extent an
Administrative Agent is the Auction Agent, each notice or other communication required to be delivered or otherwise provided to the Auction Agent (or its delegate) shall be deemed to have been given upon Auction Agent’s (or its delegate’s)
actual receipt during normal business hours of such notice or communication; provided that any notice or communication actually received outside of normal business hours shall be deemed to have been given as of the opening of business on the next
Business Day. 
 (ix) Each of the Borrower Parties and the Lenders acknowledge and agree that the Auction Agent may perform any
and all of its duties under this Section 11.5(h) by itself or through any Affiliate of the Auction Agent and expressly consents to any such delegation of duties by the Auction Agent to such Affiliate and the performance of such delegated
duties by such Affiliate. The exculpatory provisions pursuant to this Agreement shall apply to each Affiliate of the Auction Agent and its respective activities in connection with any Discounted Loan Purchase provided for in this
Section 11.5(h) as well as activities of the Auction Agent. 
 (x) Each Borrower Party shall have the right, by
written notice to the Auction Agent, to revoke or modify its offer to make a Discounted Loan Purchase and rescind the applicable Specified Discount Purchase Notice, Discount Range Solicitation Notice or Solicited Discounted Solicitation Notice
therefor at its discretion at any time on or prior to the applicable Specified Discount Purchase Response Date. 
 (xi) Any
failure by a Borrower Party to purchase Term Loans from a Lender pursuant to this Section 11.5(h) shall not constitute a Default or Event of Default under Section 9.1 or otherwise. 

(xii) To the extent the Auction Agent is required to deliver notices or communicate such other information to the Lenders pursuant to
this Section 11.5(h), the Auction Agent will work with the applicable Administrative Agent (and such Administrative Agent will cooperate with the Auction Agent) in order to procure the delivery of such notices and/or the communication of
such information to the applicable Lenders. 
 (xiii) Nothing in this Section 11.5(h) shall require the Borrower to
undertake any Discounted Loan Purchase. 
 (xiv) Each Discounted Loan Purchase shall be subject to the following conditions:

Agent to enter into amendments to the Intercreditor Agreement and the Security Agreement (each in form satisfactory to the Administrative Agent) for the purpose of allowing the Obligations and any Senior Notes to be secured by less than all of the
collateral which secures the Facilities. 
 Section 11.13 Other Relationships; No Advisory or Fiduciary

appropriate, either gender and both singular and plural, and the grammatical construction of sentences shall conform thereto. 

Section 11.15 Disclosure. The Borrower Parties agree that the Administrative Agents, and the Administrative Agents agree that

 Section 11.16 Replacement of Lender. In the event that a
Replacement Event occurs and is continuing with respect to any Lender, the Administrative Borrower may designate another financial institution (such financial institution being herein called a “Replacement Lender”) acceptable to the
applicable Administrative Agent and in the case of the Revolving Facility the Swingline Bank and the Issuing Bank, and which is not a Borrower or an Affiliate of any Borrower, to assume such Lender’s portion of the Revolving Loan Commitment
hereunder, to purchase the Loans and participations of such Lender and such Lender’s rights hereunder and (if such Lender is the Issuing Bank) to issue Letters of Credit in substitution for all outstanding Letters of Credit issued by such
Lender, without recourse to or representation or warranty by, or expense to, such Lender for a purchase price equal to the outstanding principal amount of the Loans payable to such Lender plus any accrued but unpaid interest on such Loans and
accrued but unpaid commitment fees and letter of credit fees owing to such Lender plus amounts necessary to cash collateralize any Letters of Credit issued by such Lender, and upon such assumption, purchase and substitution, and subject to the
execution and delivery to the applicable Administrative Agent by the Replacement Lender of documentation satisfactory to such Administrative Agent (pursuant to which such Replacement Lender shall assume the obligations of such original Lender under
this Agreement), the Replacement Lender shall succeed to the rights and obligations of such Lender hereunder and such Lender shall no longer be a party hereto or have any rights hereunder; provided that the obligations of the Borrowers to
indemnify such Lender with respect to any event occurring or obligations arising before such replacement shall survive such replacement; provided further that, (a) the Borrower shall have paid to the applicable Administrative Agent the
fee (if any) specified in Section 11.5(b), (b) in the case of any such assignment resulting from a claim for compensation under Section 12.3, such assignment will result in a reduction in such compensation thereafter,

consent. “Replacement Event” shall mean, with respect to any Lender, (x) the commencement of or the taking of possession by, a receiver, custodian, conservator, trustee or liquidator of such Lender, or the declaration by the
appropriate regulatory authority that such Lender is insolvent or such Lender shall become a Defaulting Lender, (y) the making of any claim by any Lender under Section 2.8(b), 12.3 or 12.5, unless the changing of the
lending office by such Lender would obviate the need of such Lender to make future claims under such Sections or (z) a refusal by such Lender to execute any amendment, waiver or consent which requires to the written consent of all of the
Lenders or each of the directly affected Lenders and to which the Majority Lenders, the Administrative Agents and the Borrowers have agreed (a “Non-Consenting Lender”). 

  
 147









 Section 11.17 Confidentiality. No member of the Lender Group shall disclose any
non-public confidential information regarding the Borrower Parties (“Confidential Information”; which shall include all information received from any Borrower Party or any of its Subsidiaries relating to any Borrower Party or any of
its Subsidiaries or any of their respective businesses, other than any such information that is available to or in the possession of the Lender Group (or any intended recipient) on a non-confidential basis prior to disclosure by any Borrower Party
or any of its Subsidiaries, provided that, such information was or is clearly identified at the time of delivery as confidential) to any other Person without the consent of the Borrowers, other than (i) to such member of the Lender
Group’s Affiliates and their officers, directors, employees, agents and advisors, to other members of the Lender Group and, as contemplated by Section 11.5, to actual or prospective assignees and participants, and then only on a

connection with the exercise of any remedy hereunder or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder. 

Section 11.18 Revival and Reinstatement of Obligations. If the incurrence or payment of the Obligations by any Borrower or
any Guarantor, or the transfer to the Lender Group of any property, should for any reason subsequently be declared to be void or voidable under any state or federal law relating to creditors’ rights, including provisions of the Bankruptcy Code
relating to fraudulent conveyances, preferences or other voidable or recoverable payments of money or transfers of property (collectively, a “Voidable Transfer”), and if the Lender Group, or any of them, is required to repay or
restore, in whole or in part, any such Voidable Transfer, or elects to do so upon the reasonable advice of its counsel, then, as to any such Voidable Transfer, or the amount thereof that the Lender Group, or any of them, is required or elects to
repay or restore, and as to all reasonable costs, expenses and attorneys fees of the Lender Group related thereto, the liability of the Borrowers or such Guarantor, as applicable, automatically shall be revived, reinstated and restored and shall
exist as though such Voidable Transfer had never been made. Moreover, each Lender severally agrees to pay to the applicable Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by such
Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders to make such repayment shall
survive the payment in full of the Obligations and the termination of this Agreement.

 Section 11.19 Electronic Transmissions. (a) Authorization. Subject to the
provisions of this Section 11.19(a), each of the Administrative Agents, the Borrowers, the Lenders, the Issuing Bank and each of their Affiliates is authorized (but not required) to transmit, post or otherwise make or communicate, in its
sole discretion, Electronic Transmissions in connection with any Loan Document and the transactions contemplated therein. Each of the Borrowers and the other Borrower Parties hereby acknowledges and agrees, and each of the Borrowers and the other
Borrower Parties shall cause each of their Subsidiaries to acknowledge and agree, that the use of Electronic Transmissions is not necessarily secure and that there are risks associated with such use, including risks of interception, disclosure and
abuse and each indicates it assumes and accepts such risks by hereby authorizing the transmission of Electronic Transmissions. 

(b) Separate Agreements. All uses of an E-System shall be governed by and subject to, in addition to the terms and conditions of
this Agreement, separate terms and conditions posted or referenced in such E-System and related contractual obligations executed by Borrower Parties or the members of the Lender Group in connection with the use of such E-System. 

(c) Limitation of Liability. All E-Systems and Electronic Transmissions shall be provided “as is” and “as
available”. None of Administrative Agent or any of its Affiliates warrants the accuracy, adequacy or completeness of any E-Systems or Electronic Transmission, and each disclaims all liability for errors or omissions therein. No warranty of any
kind is made by the Administrative Agents or any of their Affiliates in connection with any E-Systems or Electronic Transmission, including any warranty of merchantability, fitness for a particular purpose, non-infringement of third-party rights or
freedom from viruses or other code defects. Each of the Borrowers and the other Borrower Parties agrees that the Administrative Agents have no responsibility for maintaining or providing any equipment, software, services or any testing required in

Agent is required to obtain, verify and record information that identifies the Borrowers, which information includes the names and addresses of the Borrowers and other information that will allow such Lender or Administrative Agent, as applicable,
to identify the Borrowers in accordance with the USA Patriot Act. The Borrowers shall, promptly following a request by any Administrative Agent or any Lender, provide all documentation and other information that such Administrative Agent or such
Lender requests in order to comply with its ongoing obligations under applicable “know your customer” and anti-money laundering rules and regulations, including the USA Patriot Act.

 ARTICLE 12. 

YIELD PROTECTION 
 Section 12.1 Eurodollar Rate Basis Determination. Notwithstanding anything contained herein which may be construed to the contrary, if with respect to any proposed Eurodollar Loan for any
Eurodollar Loan Period, the applicable Administrative Agent (a) determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Eurodollar
Loan Period or (b) is advised by the Majority Lenders that the Eurodollar Basis for such Eurodollar Loan Period will not adequately and fairly reflect the cost to the Lenders of making or maintaining the Loans for such Eurodollar Loan Period,
such Administrative Agent shall forthwith give notice thereof to the Administrative Borrower and the Lenders, whereupon until such Administrative Agent notifies the Administrative Borrower that the circumstances giving rise to such situation no
longer exist, the obligations of the Lenders to make Eurodollar Loans shall be suspended. 
 Section 12.2
Illegality. If any change in Applicable Law, any change in the interpretation or administration of any Applicable Law by any Governmental Authority, central bank, or comparable agency charged with the interpretation or administration thereof,
or any change in compliance with Applicable Law as a result of any request or directive (whether or not having the force of law) of any such authority, central bank, or comparable agency after the Agreement Date, shall make it unlawful for any
Lender to make, maintain, or fund its Eurodollar Loans, such Lender shall so notify the applicable Administrative Agent, and such Administrative Agent shall forthwith give notice thereof to the other Lenders and the Administrative Borrower. Before
giving any notice to the applicable Administrative Agent pursuant to this Section 12.2, such Lender shall designate a different lending office if such designation will avoid the need for giving such notice and will not, in the good faith
judgment of such Lender, be otherwise disadvantageous to such Lender. Upon receipt of such notice, notwithstanding anything contained in Article 2, the Borrowers shall repay in full the then outstanding principal amount of each affected
Eurodollar Loan of such Lender, together with accrued interest thereon, either (a) on the last day of the then current Eurodollar Loan Period applicable to such Eurodollar Loan if such Lender may lawfully continue to maintain and fund such
Eurodollar Loan to such day or (b) immediately if such Lender may not lawfully continue to fund and maintain such Eurodollar Loan to such day. Concurrently with repaying each affected Eurodollar Loan of such Lender, notwithstanding anything
contained in Article 2, the Borrowers shall borrow a Base Rate Loan from such Lender, and such Lender shall make such Loan in an amount such that the outstanding principal amount of the Revolving Loans held by such Lender shall equal the
outstanding principal amount of such Revolving Loans immediately prior to such repayment. 

  
 150









 Section 12.3 Increased Costs. 

(a) If any change in Applicable Law, any change in the interpretation or administration of any Applicable Law by any Governmental
Authority, central bank, or comparable agency charged with the interpretation or administration thereof or any change in compliance with Applicable Law as a result of any request or directive (whether or not having the force of law) of such
Governmental Authority, central bank, or comparable agency after the Agreement Date: 
 (i) Shall subject an
Issuing Bank or any Lender to any tax, duty, or other charge with respect to its obligation to make Loans, or its Loans, or its obligation to issue Letters of Credit, maintain Letters of Credit or participate in Letters of Credit, or shall change
the basis of taxation of payments to any member of the Lender Group of any amounts due under or in respect of this Agreement or any other Loan Document (except for changes in the rate of tax on the overall net income of such Lender); 

(ii) Shall impose, modify, or deem applicable any reserve (including, without limitation, any imposed by the Board of
Governors of the Federal Reserve System, but excluding any included in an applicable Eurodollar Reserve Percentage), special deposit, assessment, or other requirement or condition against assets of, deposits (other than as described in
Section 12.5) with or for the account of, or commitments or credit extended by any Lender, or shall impose on any Lender or the eurodollar interbank borrowing market any other condition affecting its obligation to make such Eurodollar
Loans or its Eurodollar Loans; and the result of any of the foregoing is to increase the cost to such Lender of making or maintaining any such Eurodollar Loans, or to reduce the amount of any sum received or receivable by the Lender under this
Agreement or under any Notes with respect thereto, and such increase is not given effect in the determination of the Eurodollar Rate; or 
 (iii) Shall impose, modify, or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit, assessment, or other
requirement or condition against assets of, deposits (other than as described in Section 12.5) with or for the account of, or commitments or credit extended by the Issuing Bank, or shall impose on the Issuing Bank or any Lender any other
condition affecting the obligation to issue Letters of Credit, maintain Letters of Credit or participate in Letters of Credit; and the result of any of the foregoing is to increase the cost to the Issuing Bank or any Lender of issuing, maintaining
or participating in any such Letters of Credit or to reduce the amount of any sum received or receivable by the Issuing Bank or any Lender under this Agreement with respect thereto, 

then promptly upon demand by such Lender or Issuing Bank, the Borrowers agree to pay, without duplication of amounts due under
Section 2.8(b), to such Lender or Issuing Bank such additional amount or amounts as will compensate such Lender or Issuing Bank for such increased costs. Each Lender or Issuing Bank will promptly notify the Borrowers and the applicable
Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender or the Issuing Bank to compensation pursuant to this Section 12.3 and will designate a different lending office
if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Lender or the Issuing Bank, be otherwise disadvantageous to such Lender or the Issuing Bank. Failure or delay on the
part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 12.3 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the
Borrowers shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section 12.3 for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank notifies
the Borrowers of the change in Applicable Law or other occurrence giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the
change in Applicable Law or other occurrence giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof. 

  
 151









 (b) A certificate of any Lender or the Issuing Bank claiming compensation under this
Section 12.3 and setting forth the additional amount or amounts to be paid to it hereunder and calculations therefor shall be conclusive in the absence of manifest error. In determining such amount, such Lender or the Issuing Bank may
use any reasonable averaging and attribution methods. If any Lender demands compensation under this Section 12.3, the Borrowers may at any time, upon at least five (5) Business Days’ prior notice to such Lender, prepay in full
the then outstanding affected Eurodollar Loans of such Lender, together with accrued interest thereon to the date of prepayment, along with any reimbursement required under Section 2.9. Concurrently with prepaying such Eurodollar Loans,
the Borrowers shall borrow a Base Rate Loan, or a Eurodollar Loan not so affected, from such Lender, and such Lender shall make such Loan in an amount such that the outstanding principal amount of the Revolving Loans held by such Lender shall equal
the outstanding principal amount of such Revolving Loans immediately prior to such prepayment. 
 Section 12.4 Effect On
Other Loans. If notice has been given pursuant to Sections 12.1, 12.2 or 12.3 suspending the obligation of any Lender to make any, or requiring Eurodollar Loans of any Lender to be repaid or prepaid, then, unless and
until such Lender (or, in the case of Section 12.1, an Administrative Agent) notifies the Administrative Borrower that the circumstances giving rise to such repayment no longer apply, all Loans which would otherwise be made by such
Lender as to the Eurodollar Loans affected shall, at the option of the Administrative Borrower, be made instead as Base Rate Loans. 
 Section 12.5 Capital Adequacy. If after the Agreement Date, any Lender or Issuing Bank (or any Affiliate of the foregoing) shall have reasonably determined that the adoption of any Applicable
Law, governmental rule, regulation or order regarding the capital adequacy or liquidity of banks or bank holding companies, or any change therein, or any change in the interpretation or administration thereof by any Governmental Authority, central
bank or comparable agency charged with the interpretation or administration thereof, or compliance by such Lender or Issuing Bank (or any Affiliate of the foregoing) with any request or directive regarding capital adequacy (whether or not having the
force of law) of any such Governmental Authority, central bank or comparable agency (but only if such adoption, change, request or directive occurs after the Agreement Date), has or would have the effect of reducing the rate of return on such
Lender’s or Issuing Bank’s (or any Affiliate of the foregoing) capital as a consequence of such Lender’s or Issuing Bank’s portion of the Revolving Loan Commitment or obligations hereunder to a level below that which it could
have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or Issuing Bank’s (or any Affiliate of the foregoing) policies with respect to capital adequacy immediately before such adoption, change or
compliance and assuming that such Lender’s or Issuing Bank’s (or any Affiliate of the foregoing) capital was fully utilized prior to such adoption, change or 

  
 152









 compliance), then, promptly upon demand by such Lender or Issuing Bank, the Borrowers shall immediately pay
to such Lender or Issuing Bank such additional amounts as shall be sufficient to compensate such Lender or Issuing Bank for any such reduction actually suffered; provided, however, that there shall be no duplication of amounts paid to
a Lender pursuant to this sentence and Section 12.3; provided, further, that notwithstanding anything to the contrary contained herein, for the purposes of this Section 12.5, the following shall be deemed to
have occurred after the Agreement Date: (i) the adoption of the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder or issued in connection therewith and (ii) all requests,
rules, guidelines or directives promulgated by the Bank for International settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States regulatory authorities, in each case pursuant to Basel
III. A certificate of such Lender or Issuing Bank setting forth the amount to be paid to such Lender or Issuing Bank by the Borrowers as a result of any event referred to in this paragraph shall, absent manifest error, be conclusive. Such Lender or
the Issuing Bank will designate a different lending office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Lender or the Issuing Bank, be otherwise disadvantageous to
such Lender or the Issuing Bank. Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 12.5 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to
demand such compensation; provided that, other than in respect of matters covered by the second proviso to the first sentence of this Section 12.5, the Borrowers shall not be required to compensate a Lender or the Issuing Bank
pursuant to this Section 12.5 for any reductions in rate of return incurred more than 270 days prior to the date that such Lender or the Issuing Bank notifies the Borrowers of the change in Applicable Law or other occurrence giving rise
to such reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefore; provided further that, if the change in Applicable Law or other occurrence giving rise to such increased costs or reductions is
retroactive, then the 270 day period referred to above shall be extended to include the period of retroactive effect thereof.

 Section 13.4 All Obligations to Constitute Joint and Several Obligations.

 (a) All Obligations shall constitute joint and several obligations of the Borrowers and shall be secured by the Collateral
Agent’s Lien upon all of the Collateral, and by all other Liens heretofore, now or at any time hereafter granted by each Borrower to the Collateral Agent, for the benefit of the Lender Group, to the extent provided in the Loan Documents or Bank
Products Documents under which such Lien arises. Each Borrower expressly represents and acknowledges that it is part of a common enterprise with the other Borrowers and that any financial accommodations by the Administrative Agents, and the other
members of the Lender Group to any other Borrower hereunder and under the other Loan Documents and the Bank Products Documents are and will be of direct and indirect interest, benefit and advantage to all Borrowers. Each Borrower acknowledges that
any Request for Loan, Notice of Conversion/Continuation, Notice of Requested Commitment Increase, Request for Issuance of Letter of Credit or other notice or request given by any Borrower (including the Administrative Borrower) to the applicable
Administrative Agent shall bind all Borrowers, and that any notice given by such Administrative Agent or any other member of the Lender Group to any Borrower shall be effective with respect to all Borrowers. Each Borrower acknowledges and agrees
that each Borrower shall be liable, on a joint and several basis, for all of the Loans and other Obligations, regardless of which Borrower actually may have received the proceeds of any of the Loans or other extensions of credit or have had Letters
of Credit issued hereunder or the amount of such Loans received, Letters of Credit issued or the manner in which the applicable Administrative Agent or any other member of the Lender Group accounts among the Borrowers for such Loans, Letters of
Credit or other extensions of credit on its books and records, and further acknowledges and agrees that Loans and other extensions of credit to any Borrower inure to the mutual benefit of all of the Borrowers and that the applicable Administrative
Agent and the other members of the Lender Group are relying on the joint and several liability of the Borrowers in extending the Loans and other financial accommodations hereunder. Each Borrower shall be entitled to subrogation and contribution
rights from and against the other Borrowers to the extent any Borrower is required to pay to any member of the Lender Group any amount in excess of the Loans advanced directly to, or other Obligations incurred directly by, such Borrower or as
otherwise available under Applicable Law; provided, however, that such subrogation and contribution rights are and shall be subject to the terms and conditions of this Section 13.4. 

(b) In the event any Borrower Party (a “Funding Borrower Party”) shall make any payment or payments under this Agreement
or shall suffer any loss as a result of any realization upon any collateral granted by it to secure its obligations hereunder, such Funding Borrower Party shall have the right to seek contribution payments from each other Borrower Party (each, a
“Contributing Borrower Party”) to the extent permitted by Applicable Law. Nothing in this Section 13.4(b) shall affect any Borrower Party’s joint and several liability to the Lender Group for the entire amount of
its Obligations. Each Borrower Party covenants and agrees that (i) its right to receive any contribution hereunder from a Contributing Borrower Party shall be subordinate and junior in right of payment to all obligations of the Borrower Parties
to the Lender Group hereunder and (ii) it shall not exercise any such contribution rights unless and until the Obligations shall have been paid in full in cash (or, with respect to Letters of Credit, cash collateralized or supported by a letter
of credit) and the Revolving Loan Commitment terminated. 

  
 155









 (c) Nothing in this Section 13.4 shall affect any Borrower’s joint and
several liability to the Lender Group for the entire amount of its Obligations. Each Borrower Party covenants and agrees that its right to receive any contribution hereunder from a contributing Borrower Party shall be subordinate and junior in right
of payment to all Obligations of the Borrowers to the Lender Group hereunder. No Borrower Party will exercise any rights that it may acquire by way of subrogation hereunder or under any other Loan Document or any Bank Products Document or at law by
any payment made hereunder or otherwise, nor shall any Borrower Party seek or be entitled to seek any contribution or reimbursement from any other Borrower Party in respect of payments made by such Borrower Party hereunder or under any other Loan
Document or under any Bank Products Document, until all amounts owing to the Lender Group on account of the Obligations are paid in full in cash (or, with respect to Letters of Credit, are either cash collateralized or supported by a letter of
credit) and the Revolving Loan Commitment is terminated. If any amounts shall be paid to any Borrower Party on account of such subrogation or contribution rights at any time when all of the Obligations shall not have been paid in full, such amount
shall be held by such Borrower Party in trust for the Lender Group segregated from other funds of such Borrower Party, and shall, forthwith upon receipt by such Borrower Party, be turned over to the applicable Administrative Agent in the exact form
received by such Borrower Party (duly endorsed by such Borrower Party to the Administrative Agents, if required), to be applied against the Obligations, whether matured or unmatured, as provided for herein. 

Section 13.5 The Administrative Borrower . Each Borrower hereby irrevocably appoints Zayo as the borrowing agent and
attorney-in-fact for all Borrowers (the “Administrative Borrower”), which appointment shall remain in full force and effect unless and until any Administrative Agent shall have received prior written notice signed by each Borrower
that such appointment has been revoked and that another Borrower has been appointed the Administrative Borrower. Each Borrower hereby irrevocably appoints and authorizes the Administrative Borrower (i) to provide each Administrative Agent with
all notices with respect to Loans and Letters of Credit obtained for the benefit of any Borrower and all other notices and instructions under this Agreement and (ii) to take such action as the Administrative Borrower deems appropriate on its
behalf to obtain Loans and Letters of Credit and to exercise such other powers as are reasonably incidental thereto to carry out the purposes of this Agreement.

The “Assignor” and the “Assignee” referred to on Schedule 1 agree as follows: 

The Assignor hereby sells and assigns to the Assignee without recourse, and the Assignee hereby purchases and assumes from the Assignor,
an interest in and to the Assignor’s rights and obligations under the Credit Agreement as of the date hereof equal to the percentage interest specified on Schedule 1 of all outstanding rights and obligations under the Credit
Agreement. After giving effect to such sale and assignment, the Assignee’s Commitment and the amount of the Loans owing to the Assignee will be as set forth on Schedule 1. 

The Assignor (a) represents and warrants that it is the legal and beneficial owner of the interest being assigned by it hereunder
and that such interest is free and clear of any adverse claim, (b) makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with the Loan Documents
or the execution, legality, validity, enforceability, genuineness, sufficiency or value of the Loan Documents or any other instrument or document furnished pursuant thereto, and (c) makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Borrowers or the performance or observance by the Borrowers of any of their obligations under the Loan Documents or any other instrument or document furnished pursuant thereto.

financial statements delivered thereunder and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into this Assignment and Acceptance, (b) agrees that it will, independently

obligations that by the terms of the Credit Agreement are required to be performed by it as a Lender, and (f) attaches any U.S. Internal Revenue Service forms required under Section 2.8(b)(v) of the Credit Agreement.

same agreement. In proving this Assignment and Acceptance in any judicial proceedings, it shall not be necessary to produce or account for more than one such counterpart signed by the party against whom such enforcement is sought. Any signatures

FORM OF REVOLVING LOAN NOTE 
  

			
	US $[            ]	  	[DATE]

 FOR VALUE RECEIVED, the undersigned, ZAYO GROUP, LLC, a Delaware limited liability company (the
“Administrative Borrower”) and ZAYO CAPITAL, INC., a Delaware corporation (“Zayo Capital”; and together with Administrative Borrower, each, individually a “Borrower” and, collectively, the
“Borrowers”), hereby, jointly and severally, promise to pay to the order of [            ] (hereinafter, together with its successors and assigns, the
“Lender”), at the office of the Administrative Agent (as defined below), in immediately available funds, the principal sum of [            and
            /100s DOLLARS ($            )] of United States funds, or, if less, so much thereof as may from time to time be
advanced and outstanding as Revolving Loans by the Lender to the Borrowers hereunder, plus interest as hereinafter provided. Such Revolving Loans may be endorsed from time to time on the grid attached hereto, but the failure to make such notations
shall not affect the validity of the Borrowers’ obligations to repay unpaid principal and interest hereunder. 
 This Note
is one of the Revolving Loan Notes referred to in that certain Credit Agreement, dated as of July 2, 2012 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; capitalized terms
used herein without definitions shall have the meanings ascribed thereto in the Credit Agreement), by and among the Borrowers, the Persons party thereto from time to time as Guarantors, the financial institutions party thereto from time to time as
lender, SUNTRUST BANK, as the Issuing Bank, SUNTRUST BANK, as the Collateral Agent, MORGAN STANLEY SENIOR FUNDING, INC., as administrative agent for the Term Loan Facility (in such capacity, the “Term Facility Administrative
Agent”), and SUNTRUST BANK, as the administrative agent for the Revolving Loan Facility (in such capacity, the “Revolving Facility Administrative Agent” and, together with the Term Facility Administrative Agent, each,
individually an “Administrative Agent” and, collectively, the “Administrative Agents”). 
 All
principal amounts and other Obligations then outstanding hereunder shall be due and payable in full on the Maturity Date, or such earlier date as the Revolving Loans shall be due and payable in full, whether by acceleration or otherwise, pursuant to
the Credit Agreement. The Borrowers also shall repay the principal outstanding hereunder from time to time as provided in the Credit Agreement. 
 The Borrowers shall be entitled to borrow, repay and re-borrow funds hereunder pursuant to the terms and conditions of the Credit Agreement. Prepayment of the principal amount of any Revolving Loan may be
made only as provided in the Credit Agreement. 
 The Borrowers hereby, jointly and severally, promise to pay interest on the
unpaid principal amount hereof as provided in Article 2 of the Credit Agreement. Interest under this Note also shall be due and payable when this Note shall become due (whether at maturity, by reason of acceleration or otherwise). If all or a
portion of (i) the principal amount of any Loan or (ii) any interest payable thereon shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum
which is the rate that would otherwise be applicable thereto pursuant to the provisions of Section 2.3 of the Credit Agreement plus 2.00% per annum from the date of such non-payment until the earliest to occur of (i) waiver of the
applicable Event of Default in accordance with Section 11.12 of the Credit Agreement, (ii) agreement by the Majority Lenders, to rescind the charging of interest at the Default Rate, or (iii) payment in full of the Obligations.








 In no event shall the amount of interest due or payable hereunder exceed the maximum rate of
interest allowed by Applicable Law, and in the event any such payment is inadvertently made by the Borrowers or inadvertently received by the Lender, then such excess sum shall be credited as a payment of principal, unless the Borrowers shall notify
the Lender in writing that it elects to have such excess sum returned forthwith. It is the express intent hereof that the Borrowers not pay, and the Lender not receive, directly or indirectly, in any manner whatsoever, interest in excess of that
which may legally be paid by the Borrowers under Applicable Law. 
 This Note is one of the Notes referred to in, and is
entitled to the benefits of, the Credit Agreement. The Credit Agreement, among other things, (i) provides for the making of the Revolving Loans by the Lender to the Borrower in an amount not to exceed the U.S. dollar amount first above
mentioned, the indebtedness of the Borrower resulting from such Revolving Loan being evidenced by this Note, and (ii) contains provisions for acceleration of the maturity hereof upon the happening of certain stated events and also for
prepayments on account of principal hereof prior to the maturity hereof upon the terms and conditions therein specified. The Obligations of the Borrowers under this Note and the other Loan Documents, and the Obligations of the other Borrower Parties
under the Loan Documents, are secured by the Collateral as provided in the Loan Documents. 
 The Borrowers hereby, jointly and
severally, for themselves and their successors and assigns, hereby waive diligence, presentment for payment, protest and demand and notice of protest, demand, dishonor and non-payment of this Note. 

No delay or omission on the part of the Lender or any holder hereof in exercising its rights under this Note, or delay or omission on the
part of the Lender, the applicable Administrative Agent, the Majority Lenders or the Lender Group, or any of them, in exercising its or their rights under the Credit Agreement or under any other Loan Document, or course of conduct relating thereto,
shall operate as a waiver of such rights or any other right of the Lender or any holder hereof, nor shall any waiver by the Lender, the applicable Administrative Agent, the Majority Lenders or the Lender Group, or any of them, or any holder hereof,
of any such right or rights on any one occasion be deemed a bar to, or waiver of, the same right or rights on any future occasion. 
 Time is of the essence in this Note. 
 This Note shall be construed in accordance
with and governed by the laws of the State of New York.

 The Borrowers promise to pay interest on

Both principal and interest are payable in lawful money of the United States of America to Morgan Stanley Senior Funding, Inc. as Term
Facility Administrative Agent, at such office and in the manner specified in the Credit Agreement. The Term Loan owing to the Lender by the Borrowers and the maturity thereof, and all payments made on account of principal thereof, shall be recorded

Obligations of the Borrowers under this Note.

prior to the maturity hereof upon the terms and conditions therein specified. The Obligations of the Borrowers under this Note and the other Loan Documents, and the Obligations of the other Borrower Parties under the Loan Documents, are secured by
the Collateral as provided in the Loan Documents. 







 No delay or omission on the part of the Lender or any holder hereof in exercising its rights
under this Note, or delay or omission on the part of the Lender, the applicable Administrative Agent, the Majority Lenders or the Lender Group, or any of them, in exercising its or their rights under the Credit Agreement or under any other Loan
Document, or course of conduct relating thereto, shall operate as a waiver of such rights or any other right of the Lender or any holder hereof, nor shall any waiver by the Lender, the applicable Administrative Agent, the Majority Lenders or the
Lender Group, or any of them, or any holder hereof, of any such right or rights on any one occasion be deemed a bar to, or waiver of, the same right or rights on any future occasion. 

The Borrowers hereby, jointly and severally, for themselves and their successors and assigns, hereby waive diligence, presentment for
payment, protest and demand and notice of protest, demand, dishonor and non-payment of this Note. 
 This Note may not be
transferred or assigned by the Lender to any Person except in compliance with the terms of the Credit Agreement. The rights evidenced by this Note to receive principal and interest may only be transferred if the transfer is registered on a record of
ownership and the transferee is identified as the owner of an interest in the obligation pursuant to Section 11.5 of the Credit Agreement. This Note may not at any time be endorsed to, or to the order of, bearer.

 Whereas, pursuant to Section 6.16 of the Credit Agreement, a new Restricted Subsidiary that is a Domestic
Subsidiary (whether by acquisition, creation or designation) of the Borrowers is required to join the Credit Agreement as a Guarantor and become a Borrower Party by executing and delivering in favor of the Administrative Agent this Guaranty
Supplement. Upon the execution and delivery of this Guaranty Supplement by such Restricted Subsidiary that is a Domestic Subsidiary, such Restricted Subsidiary shall become a Guarantor of the Obligations and become a Borrower Party under the Credit
Agreement with the same force and effect as if originally named as a Guarantor therein. 
 The undersigned (the “New

the Lender Group, the full and prompt payment of the Obligations, including, without limitation, any interest thereon (including, without limitation, interest, as provided in the Credit Agreement, accruing after the filing of a petition initiating
any Insolvency Proceedings, whether or not such interest accrues or is recoverable against the Borrowers after the filing of such petition for purposes of the Bankruptcy Code or is an allowed claim in such proceeding), plus, solely to the extent
provided for in the Credit Agreement, reasonable attorneys’ fees and expenses if the obligations represented by the Credit Agreement are collected by law, through an attorney-at-law, or under advice therefrom. Each reference to a
“Guarantor” and “Borrower Party” in the Credit Agreement shall be deemed to include the New Guarantor. The Credit Agreement is incorporated herein by reference. 







 The New Guarantor represents and warrants to the Administrative Agents and the other members
of the Lender Group that this Guaranty Supplement has been duly executed and delivered by the New Guarantor and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, except to the extent that the
enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, or similar laws affecting the enforcement of creditors’ rights generally or by general principles of equity (regardless of whether such enforcement is
considered in a proceeding in equity or at law). 
 This Guaranty Supplement may be executed in any number of counterparts, each
of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same agreement. In proving this Guaranty Supplement in any judicial proceedings, it shall not be necessary to produce or account
for more than one such counterpart signed by the party against whom such enforcement is sought. Any signatures delivered by a party by facsimile transmission or other electronic transmission shall be deemed an original signature hereto. 

Except as expressly supplemented hereby, the Credit Agreement shall remain in full force and effect. 

THIS GUARANTY SUPPLEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. 

This Guaranty Supplement shall be considered a Loan Document for all purposes.

Taxes 
 Examinations or Audits 
 FiberNet 2009 federal tax return audit in process

 The Company received notification from the IRS of its intent to audit the tax return of American Fiber Systems
(“AFS”) for the short year ended September 30, 2010. No material issues are expected as AFS had been audited through the 2009 year. 
 AboveNet, Inc. tax audit for the state of New York in process. 
 AboveNet, Inc. New
York City utility tax audit in process. 
 AboveNet, Inc. federal income tax audit in process. 

Payment, filing of taxes and pending adjustments 
 Although the FiberNet 2009 federal tax audit is not complete, there is a known adjustment of $26,833,954 to the originally claimed net operating loss of $49,620,715, resulting in a new net operating loss
of $22,786,761. The adjustment relates to the disallowance of a deduction for warrants exercised that was calculated incorrectly. Although the audit is not complete, this is the only expected adjustment and will be adjusted by the IRS as part of the
closing process. 
 Legacy FiberNet tax assessment paid in the amount of $96,227.08 for Los Angeles city utility tax and business
license from 2006-2011. 
 AboveNet, Inc. has withheld taxes required by the Universal Service Administrative Company for
payments related to transmission relay services (“TRS”), currently totaling approximately $5.9 million; however, AboveNet has not received any invoices for such taxes and has yet to remit the amounts withheld. AboveNet also withheld
approximately $2.9 million in fees charged to customers pursuant to New York Tax Law § 186-a; however, AboveNet believes that such fees should not have been charged and intends to remit all such fees to the respective customers. Additionally,
AboveNet has approximately $1.6 million of accrued transaction taxes in certain jurisdictions which are accrued but have not been remitted. 







 Extensions or Waivers 

The statute of limitations for AboveNet’s federal tax returns for the period January 1, 2005 to March 31, 2009 has been
extended through June 30, 2012.
