 2.1 Loans; Commitments. 
  

 35 







 (a) Subject to the terms and conditions hereof, each Revolving Lender severally agrees to make revolving
credit loans (“Revolving Loans”) to the Borrower from time to time during the Revolving Commitment Period in an aggregate principal amount at any one time outstanding which, when added to such Lender’s Revolving Percentage of
the sum of (a) the L/C Obligations then outstanding and (b) the aggregate principal amount of the Swingline Loans then outstanding, does not exceed the amount of such Lender’s Revolving Commitment. During the Revolving Commitment
Period the Borrower may use the Revolving Commitments by borrowing, prepaying the Revolving Loans in whole or in part, and reborrowing, all in accordance with the terms and conditions hereof. 
 (b) The Revolving Loans and Term Loans, if any, may from time to time be Eurodollar Loans or ABR Loans, as determined by the Borrower and notified to the
Administrative Agent in accordance with Sections 2.2 and 2.10. 
 2.2 Procedure for Borrowing. In order to effect a borrowing
hereunder, the Borrower shall give the Administrative Agent written irrevocable notice (which notice must be received by the Administrative Agent prior to 12:00 Noon, New York City time, (a) three Business Days prior to the requested Borrowing
Date, in the case of Eurodollar Loans, or (b) one Business Day prior to the requested Borrowing Date, in the case of ABR Loans), specifying (i) the Facility under which such borrowing is to be made, (ii) the amount and Type of Loans
to be borrowed, (iii) the requested Borrowing Date and (iv) in the case of Eurodollar Loans, the respective amounts of each such Type of Loan and the respective lengths of the initial Interest Period therefor. Each borrowing shall be in an
aggregate amount equal to (x) in the case of ABR Loans, $5,000,000 or a whole multiple of $1,000,000 in excess thereof (or, if the then aggregate Available Revolving Commitments are less than $5,000,000, such lesser amount) and (y) in the
case of Eurodollar Loans, $5,000,000 or a whole multiple of $1,000,000 in excess thereof (or, if the then aggregate Available Revolving Commitments are less than $5,000,000, such lesser amount); provided that the Swingline Lender may request,
on behalf of the Borrower, borrowings under the Revolving Commitments that are ABR Loans in other amounts pursuant to Section 2.5; and provided, further, that Revolving Loans that refund draws under the Letters of Credit or
Swingline Loans may be in amounts less than specified above. Upon receipt of any such notice from the Borrower, the Administrative Agent shall promptly notify each relevant Lender thereof. Each relevant Lender will make the amount of its pro rata
share of each borrowing available to the Administrative Agent for the account of the Borrower at the Funding Office prior to 12:00 Noon, New York City time, on the Borrowing Date requested by the Borrower in funds immediately available to the
Administrative Agent. Such borrowing will then be made available to the Borrower by the Administrative Agent crediting the account of the Borrower on the books of such office with the aggregate of the amounts made available to the Administrative
Agent by the relevant Lenders and in like funds as received by the Administrative Agent. 
 2.3 Repayment of Loans; Early Maturity.

  

 36 







 (a) (i) All then outstanding Revolving Loans shall be repaid, and all then outstanding Revolving
Commitments shall be terminated, on the Revolving Termination Date and (ii) all then outstanding Term Loans shall be repaid on the applicable final maturity date as set forth in the Term Loan Joinder pursuant to which such Term Loans are made.

 (b) Notwithstanding anything to the contrary in this Agreement, all outstanding Loans shall be repaid and all outstanding Commitments
shall be terminated on the date that is six months prior to the date of any scheduled maturity or redemption of the Holdings Existing Preferred Stock (unless the Holdings Existing Preferred Stock has been amended, amended and restated, replaced,
refinanced or otherwise modified so that the scheduled maturity or redemption date thereof is at least six months after the maturity date of all outstanding Term Loans) or any preferred stock issued by Holdings after the Closing Date that has a
maturity date earlier than six months following the maturity date of all outstanding Term Loans. For avoidance of doubt, if any preferred stock of Holdings is refinanced or otherwise extended such that it becomes scheduled to mature or be redeemed
on a later date, such preferred stock will be considered thereafter to be scheduled to mature or be redeemed on such later date. 
 (c) At
least 45 days but not more than 60 days prior to the Revolving Termination Date, the Borrower may, by written notice to the Administrative Agent (which notice the Administrative Agent shall promptly transmit to each Revolving Lender), request that
each Revolving Lender agree to an extension of the Revolving Termination Date for a period of 364 days from its then scheduled expiration. Each Revolving Lender shall respond to such extension request (each such response being delivered to the
Administrative Agent) in accordance with instructions provided by the Administrative Agent (which response shall not be required earlier than 30 days (such date, the “Last Response Date”) prior to the Revolving Termination Date),
with the failure of any Revolving Lender to respond being deemed to be a negative response. Each Revolving Lender shall decide in its sole discretion whether or not to agree to such extension of the Revolving Termination Date. So long as the
Majority Facility Lenders (including, for this purpose any Replacement Lender (as defined below) and excluding any Non-Extending Lender (as defined below) that will be replaced by a Replacement Lender) under the Revolving Facility have approved such
extension request and no Default or Event of Default is in existence at such time, then each Revolving Lender that has responded affirmatively as set forth above (each such Revolving Lender, an “Extending Lender”) shall be deemed to
have agreed (such agreement to become effective on the then effective Revolving Termination Date (such date, as “Extension Date”)) to cause the Revolving Termination Date to be extended as to each Extending Lender until the date
which is 364 days after the then effective Revolving Termination Date. In the event that one or more Revolving Lenders (each, a “Non-Extending Lender”) do not agree to such extension, the Borrower may elect, with respect to each
such Non-Extending Lender, on or before the Revolving Termination Date then in effect, to have, with the consent of the Administrative Agent, another bank or financial institution or entity (each, a “Replacement Lender”) acquire the
Revolving Commitment of and Revolving Loans owing to each such Non-Extending Lender, which assignment of each such Non-Extending Lender’s Revolving Commitment and Revolving Loans shall be effected pursuant to an Assignment and Assumption
executed by the applicable Non-Extending Lender, such other bank or financial institution or entity, the Borrower and the Administrative Agent. On such Extension Date, the 

  

 37 







 
Revolving Commitment of any Non-Extending Lender shall, unless assigned in accordance with the immediately preceding sentence, automatically terminate in
whole without any further notice or other action by the Borrower, such Non-Extending Lender or any other Person and all principal, interest and fees owing to such Non-Extending Lender shall be paid in full by the Borrower; provided that such
Non-Extending Lender’s rights under Sections 2.16, 2.17, 2.18, 2.22 and 10.5 shall survive the Extension Date for such Non-Extending Lender as to matters occurring on or prior to such date. 
 2.4 Swingline Commitment. 
 (a)
Subject to the terms and conditions hereof, the Swingline Lender agrees to make a portion of the credit otherwise available to the Borrower under the Revolving Commitments from time to time during the Revolving Commitment Period by making swingline
loans (“Swingline Loans”) to the Borrower; provided that (i) the aggregate principal amount of Swingline Loans outstanding at any time shall not exceed the Swingline Commitment then in effect (notwithstanding that the Swingline
Loans outstanding at any time, when aggregated with the Swingline Lender’s other outstanding Revolving Loans hereunder, may exceed the Swingline Commitment then in effect) and (ii) the Borrower shall not request, and the Swingline Lender
shall not make, any Swingline Loan if, after giving effect to the making of such Swingline Loan, the aggregate amount of the Available Revolving Commitments would be less than zero. During the Revolving Commitment Period, the Borrower may use the
Swingline Commitment by borrowing, repaying and reborrowing, all in accordance with the terms and conditions hereof. Swingline Loans shall be ABR Loans only. 
 (b) The Borrower shall repay all outstanding Swingline Loans on the Revolving Termination Date. 
 2.5
Procedure for Swingline Borrowing; Refunding of Swingline Loans. 
 (a) Whenever the Borrower desires that the Swingline Lender make
Swingline Loans it shall give the Swingline Lender irrevocable telephonic notice confirmed promptly in writing (which telephonic notice must be received by the Swingline Lender not later than 2:00 P.M., New York City time, on the proposed Borrowing
Date), specifying (i) the amount to be borrowed and (ii) the requested Borrowing Date (which shall be a Business Day during the Revolving Commitment Period). Each borrowing under the Swingline Commitment shall be in an amount equal to
$500,000 or a whole multiple of $100,000 in excess thereof. Not later than 3:00 P.M., New York City time, on the Borrowing Date specified in a notice in respect of Swingline Loans, the Swingline Lender shall make available to the Administrative
Agent at the Funding Office an amount in immediately available funds equal to the amount of the Swingline Loan to be made by the Swingline Lender. The Administrative Agent shall make the proceeds of such Swingline Loan available to the Borrower on
such Borrowing Date by depositing such proceeds in the account of the Borrower with the Administrative Agent on such Borrowing Date in immediately available funds. 
  

 38 







 (b) The Swingline Lender, at any time and from time to time in its sole and absolute discretion may, on
behalf of the Borrower (which hereby irrevocably directs the Swingline Lender to act on its behalf), on one Business Day’s notice given by the Swingline Lender no later than 12:00 Noon, New York City time, request each Revolving Lender to make,
and each Revolving Lender hereby agrees to make, a Revolving Loan, in an amount equal to such Revolving Lender’s Revolving Percentage of the aggregate amount of the Swingline Loans (the “Refunded Swingline Loans”) outstanding
on the date of such notice, to repay the Swingline Lender. Each Revolving Lender shall make the amount of such Revolving Loan available to the Administrative Agent at the Funding Office in immediately available funds, not later than 10:00 A.M., New
York City time, one Business Day after the date of such notice. The proceeds of such Revolving Loans shall be immediately made available by the Administrative Agent to the Swingline Lender for application by the Swingline Lender to the repayment of
the Refunded Swingline Loans. 
 (c) If prior to the time a Revolving Loan would have otherwise been made pursuant to Section 2.5(b),
one of the events described in Section 8(f) shall have occurred and be continuing with respect to the Borrower or if for any other reason, as determined by the Swingline Lender in its sole discretion, Revolving Loans may not be made as
contemplated by Section 2.5(b), each Revolving Lender shall, on the date such Revolving Loan was to have been made pursuant to the notice referred to in Section 2.5(b) (the “Refunding Date”), purchase for cash an undivided
participating interest in the then outstanding Swingline Loans by paying to the Swingline Lender an amount (the “Swingline Participation Amount”) equal to (i) such Revolving Lender’s Revolving Percentage times
(ii) the sum of the aggregate principal amount of Swingline Loans then outstanding that were to have been repaid with such Revolving Loans. 
 (d) Whenever, at any time after the Swingline Lender has received from any Revolving Lender such Lender’s Swingline Participation Amount, the Swingline Lender receives any payment on account of the Swingline Loans, the Swingline Lender
will distribute to such Lender its Swingline Participation Amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded and, in the
case of principal and interest payments, to reflect such Lender’s pro rata portion of such payment if such payment is not sufficient to pay the principal of and interest on all Swingline Loans then due); provided, however, that in
the event that such payment received by the Swingline Lender is required to be returned, such Revolving Lender will return to the Swingline Lender any portion thereof previously distributed to it by the Swingline Lender. 
 (e) Each Revolving Lender’s obligation to make the Loans referred to in Section 2.5(b) and to purchase participating interests pursuant to
Section 2.5(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such Revolving Lender or the Borrower may have against the
Swingline Lender, the Borrower or any other Person for any reason whatsoever; (ii) the occurrence or continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions specified in Section 5;
(iii) any adverse change in the 

  

 39 







 
condition (financial or otherwise) of the Borrower; (iv) any breach of this Agreement or any other Loan Document by the Borrower, any other Loan Party
or any other Revolving Lender; or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. 
 2.6 Commitment Fees, etc. 
 (a) The Borrower agrees to pay to the Administrative Agent for the account of each Revolving
Lender a nonrefundable commitment fee for the period from and including the Closing Date to the last day of the Revolving Commitment Period, computed at the Commitment Fee Rate on the average daily amount of the Available Revolving Commitment of
such Lender during the period for which payment is made, payable quarterly in arrears on the last day of each March, June, September and December and on the Revolving Termination Date. 
 (b) The Borrower agrees to pay to the Administrative Agent or any Lender the fees in the amounts and on the dates previously agreed to in writing by the
Borrower and the Administrative Agent or such Lender. 
 2.7 Termination or Reduction of Commitments. The Borrower shall have the
right, upon not less than three Business Days’ notice to the Administrative Agent, to terminate the Revolving Commitments or, from time to time, to reduce the amount of the Revolving Commitments; provided that no such termination or
reduction of Revolving Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Revolving Loans and Swingline Loans made on the effective date thereof, the Total Revolving Extensions of Credit would exceed the
Total Revolving Commitments. Any such reduction shall be in an amount equal to $5,000,000, or a whole multiple of $1,000,000 in excess thereof, and shall reduce permanently the Revolving Commitments then in effect. 
 2.8 Optional Prepayments. The Borrower may at any time and from time to time prepay the Loans, in whole or in part, without premium or penalty,
upon irrevocable notice delivered to the Administrative Agent at least three Business Days prior thereto in the case of Eurodollar Loans and at least one Business Day prior thereto in the case of ABR Loans, which notice shall specify the date and
amount of prepayment and whether the prepayment is of Eurodollar Loans or ABR Loans; provided that if a Eurodollar Loan is prepaid on any day other than the last day of the Interest Period applicable thereto, the Borrower shall also pay any
amounts owing pursuant to Section 2.18. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on
the date specified therein, together with (except in the case of Revolving Loans that are ABR Loans and Swingline Loans) accrued interest to such date on the amount prepaid. Partial prepayments of Term Loans and Revolving Loans shall be in an
aggregate principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Partial prepayments of Swingline Loans shall be in an aggregate principal amount of $1,000,000 or a whole multiple of $500,000 in excess thereof.

 (a) If any Indebtedness shall be incurred by the Borrower or any Subsidiary (excluding any Excluded Indebtedness), (i) in the case of the incurrence
of any such Indebtedness in the form of Additional Tower Notes, the proceeds thereof shall, as soon as such proceeds become available to the Issuer Entity, but in any event no later than the next Payment Date (as that term is defined in the Tower
Notes Indenture) in respect of the Collection Period (as that term is defined in the Tower Notes Indenture) in which such Additional Tower Notes are issued, be applied toward the prepayment of the Term Loans and the reduction of the Revolving
Commitments as set forth in Section 2.9(e) in an amount equal to the lesser of (y) 100% of the aggregate face amount of such Additional Tower Notes, net of any expenses reasonably incurred by the Issuers in connection with such issuance,
or (z) if such proceeds are deposited into the Collection Account, the amount available to be distributed to or at the direction of the Issuer Entity pursuant to clause Twentieth of Section 5.01(a) of the Tower Notes Indenture on such next
Payment Date and (ii) in the case of the incurrence of all other such Indebtedness, an amount equal to 100% of the Net Cash Proceeds thereof shall be applied on the date of such incurrence toward the prepayment of the Term Loans and the
reduction of the Revolving Commitments as set forth in Section 2.9(e).

its Subsidiaries (excluding (i) Capital Stock issued to the Borrower or any other Subsidiary of Holdings, (ii) Capital Stock issued by Holdings and contributed to the Borrower solely for the purpose of making an Investment permitted by
Section 7.7(i), (iii) Capital Stock issued by Holdings in connection with the Global Signal Acquisition and (iv) Capital Stock issued by Holdings to any of its officers, directors, employees or consultants pursuant to any employee
benefit plan, stock purchase plan or employment agreement approved by the board of directors of Holdings), an amount equal to 50% of the Net Cash Proceeds thereof shall be applied on the date of such incurrence toward the prepayment of the Term Loan
and the reduction of the Revolving Commitments as set forth in Section 2.9(e). 
 (c) If on any date the Borrower or any Subsidiary
shall receive Net Cash Proceeds from any Asset Sale or Recovery Event then, unless such proceeds are required to be applied to (x) the redemption of the Tower Notes pursuant to the Tower Notes Indenture or (y) upon and after consummation
of the Global Signal Acquisition, the prepayment of the Global Signal 2004 Loans or the Global Signal 2006 Loans pursuant to the Global Signal 2004 Loan Agreement or the Global Signal 2006 Loan Agreement, as applicable, or a Reinvestment Notice
shall be delivered in respect thereof, such Net Cash Proceeds shall be applied on such date toward the prepayment of the Term Loans and the reduction of the Revolving Commitments as set forth in Section 2.9(e); provided that,
notwithstanding the foregoing, (i) the aggregate Net Cash Proceeds of Asset Sales and Recovery Events that may be excluded from the foregoing requirement pursuant to a Reinvestment Notice shall not exceed $20,000,000 in any fiscal year of the
Borrower and (ii) on each Reinvestment Prepayment Date, an amount equal to the Reinvestment Prepayment Amount with respect to the relevant Reinvestment Event shall be

 (d) If, for any fiscal year of the Borrower commencing with the fiscal year ending December 31, 2007, there shall be Excess Cash Flow, the Borrower
shall, on the relevant Excess Cash Flow Application Date, apply 50% of such Excess Cash Flow toward the prepayment of the Term Loans and the reduction of the Revolving Commitments as set forth in Section 2.9(e); provided that if a Cash
Trap Condition, or upon and after consummation of the Global Signal Acquisition, a Cash Trap Event has occurred and is continuing, then only that portion of Excess Cash Flow that is distributed to the Borrower by the Subsidiaries shall be required
to be applied pursuant to this Section 2.9(d). Each such prepayment and commitment reduction shall be made on a date (an “Excess Cash Flow Application Date”) no later than five days after the earlier of (i) the date on
which the financial statements of the Borrower referred to in Section 6.1(b), for the fiscal year with respect to which such prepayment is made, are required to be delivered to the Lenders and (ii) the date such financial statements are
actually delivered. 
 (e) Amounts to be applied in connection with prepayments and Commitment reductions made pursuant to this
Section 2.9 shall be applied, first, to prepay the Term Loans and, second, to reduce permanently the Revolving Commitments; provided that any prepayments and commitment reductions made pursuant to Section 2.9(c) shall be made on a
pro rata basis to the prepayment of Terms Loans and to reduce permanently the Revolving Commitments. Any reduction of the Revolving Commitments shall be accompanied by prepayment of the Revolving Loans and/or Swingline Loans to the extent, if any,
that the Total Revolving Extensions of Credit exceed the amount of the Total Revolving Commitments as so reduced; provided that if the aggregate principal amount of Revolving Loans and Swingline Loans then outstanding is less than the amount
of such excess (because L/C Obligations constitute a portion thereof), the Borrower shall, to the extent of the balance of such excess, replace outstanding Letters of Credit and/or deposit an amount in cash in a cash collateral account established
with the Administrative Agent for the benefit of the Lenders on terms and conditions satisfactory to the Administrative Agent. The application of any prepayment pursuant to this Section 2.9 shall be made, first, to ABR Loans and, second, to
Eurodollar Loans. Each prepayment of the Loans under this Section 2.9 (except in the case of Revolving Loans that are ABR Loans and Swingline Loans) shall be accompanied by accrued interest to the date of such prepayment on the amount prepaid.

 2.10 Conversion and Continuation Options. 
 (a) The Borrower may elect from time to time to convert Eurodollar Loans to ABR Loans by giving the Administrative Agent at least three Business Days’ prior written irrevocable notice of such election;
provided that any such conversion of Eurodollar Loans may only be made on the last day of an Interest Period with respect thereto. The Borrower may elect from time to time to convert ABR Loans to Eurodollar Loans by giving the Administrative
Agent at least three Business Days’ prior written irrevocable notice of such election (which notice shall specify the length of the initial Interest Period therefor); provided that no ABR Loan under a particular Facility may be converted
into a Eurodollar Loan when any Event of Default 

  

 42 







 
has occurred and is continuing and the Administrative Agent or the Majority Facility Lenders in respect of such Facility have determined in its or their sole
discretion not to permit such conversions. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. 
 (b) Any Eurodollar Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Borrower giving written irrevocable notice to the Administrative Agent, in
accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Loans; provided that no Eurodollar Loan under a particular
Facility may be continued as such when any Event of Default has occurred and is continuing and the Administrative Agent has or the Majority Facility Lenders in respect of such Facility have determined in its or their sole discretion not to permit
such continuations; and provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso each such Loan shall
be automatically converted to a Eurodollar Loan with an Interest Period of one month on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

 2.11 Limitations on Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions
and continuations of Eurodollar Loans hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the
Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no more than twenty Eurodollar Tranches shall be outstanding at any one time. 
 2.12 Interest Rates and Payment Dates. 
 (a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin. 
 (b) Each ABR Loan shall bear interest at a rate per annum equal to the ABR plus the Applicable Margin. 
 (c) (i) If all or a portion of the principal amount of any Loan or Reimbursement Obligation 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 equal to (x) in the case of the Loans, the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2%
or (y) in the case of Reimbursement Obligations, the rate applicable to ABR Loans under the Revolving Facility plus 2%, and (ii) if all or a portion of any interest payable on any Loan or Reimbursement Obligation or any commitment fee or
other amount payable hereunder shall not be paid when due (whether at the stated maturity, 

  

 43 







 
by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the rate then applicable to ABR Loans under the relevant
Facility plus 2% (or, in the case of any such other amounts that do not relate to a particular Facility, the rate then applicable to ABR Loans under the Revolving Facility plus 2%), in each case, with respect to clauses (i) and (ii) above,
from the date of such non-payment until such amount is paid in full (as well after as before judgment). 
 (d) Interest shall be payable in
arrears on each Interest Payment Date; provided that interest accruing pursuant to paragraph (c) of this Section shall be payable from time to time on demand. 
 2.13 Computation of Interest and Fees. 
 (a) Interest and fees payable pursuant hereto shall be
calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to ABR Loans the rate of interest on which is calculated on the basis of the Prime Rate, the interest thereon shall be calculated on the basis of a 365-
(or 366-, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a
Loan resulting from a change in the ABR or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the
Borrower and the relevant Lenders of the effective date and the amount of each such change in interest rate. 
 (b) Each determination of an
interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower,
deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.12(a). 
 2.14 Inability to Determine Interest Rate. If prior to the first day of any Interest Period: 
 (a) the
Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the
Eurodollar Rate for such Interest Period, or 
 (b) the Administrative Agent shall have received notice from the Majority Facility Lenders in
respect of the relevant Facility that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining
their affected Loans during such Interest Period, 

  

 44 







 the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the relevant Lenders as
soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans under the relevant Facility requested to be made on the first day of such Interest Period shall be made as ABR Loans, (y) any Loans under the relevant
Facility that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and (z) any outstanding Eurodollar Loans under the relevant Facility shall be converted, on the last day of
the then-current Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans under the relevant Facility shall be made or continued as such, nor shall the Borrower have the right to
convert Loans under the relevant Facility to Eurodollar Loans. 
 2.15 Pro Rata Treatment and Payments. 
 (a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee and any reduction of the
Revolving Commitments of the Lenders shall be made pro rata according to the respective Term Loan Commitments or Revolving Commitments, as the case may be, of the relevant Lenders. 
 (b) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Term Loans shall be made pro rata according
to the respective outstanding principal amounts of the Term Loans then held by the Term Loan Lenders (except as otherwise provided in Section 2.15(d)). Any prepayment of Term Loans shall be applied (i) in the case of prepayments made
pursuant to Section 2.8, to reduce the remaining scheduled repayments of Term Loans as directed by the Borrower and (ii) in the case of prepayments made pursuant to Section 2.9, (A) first, to reduce, in direct order of maturity,
the scheduled repayments of the Term Loans on the two consecutive scheduled payment dates next following the date of such prepayment unless and until each such scheduled repayment has been eliminated as a result of reductions hereunder and
(B) second, to reduce ratably the remaining scheduled repayments of the Term Loans. Amounts repaid or prepaid on account of the Term Loans may not be reborrowed. 
 (c) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Revolving Loans shall be made pro rata according to the respective outstanding principal amounts of the
Revolving Loans then held by the Revolving Lenders. 
 (d) Notwithstanding anything to the contrary in this Agreement, with respect to the
amount of any mandatory prepayment of the Term Loans pursuant to Section 2.9 that is allocated to Term Loans (such amount, the “Term Loan Prepayment Amount”), at any time when Revolving Loans remain outstanding, the Borrower
will, in lieu of applying such amount to the prepayment of Term Loans, on the date specified in Section 2.9 for such prepayment, give the Administrative Agent telephonic notice (promptly confirmed in writing) requesting that the Administrative
Agent prepare and provide to each Term Loan Lender a notice (each, a “Prepayment Option Notice”) as described below. As promptly as practicable after receiving 

  

 45 







 
such notice from the Borrower, the Administrative Agent will send to each Term Loan Lender a Prepayment Option Notice, which shall be in the form of Exhibit
G, and shall include an offer by the Borrower to prepay on the date (each a “Prepayment Date”) that is 10 Business Days after the date of the Prepayment Option Notice, the Term Loans of such Lender by an amount equal to the portion
of the Prepayment Amount indicated in such Lender’s Prepayment Option Notice as being applicable to such Lender’s Term Loans. On the Prepayment Date, (i) the Borrower shall pay to the relevant Term Loan Lenders the aggregate amount
necessary to prepay that portion of the outstanding relevant Term Loans in respect of which such Lenders have accepted prepayment as described in the Prepayment Option Notice and (ii) the Borrower shall pay to the Revolving Lenders an amount
equal to the portion of the Term Loan Prepayment Amount not accepted by the relevant Lenders, and such amount shall be applied to the prepayment of the Revolving Loans (and a permanent reduction of the Revolving Commitments). 
 (e) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be
made without setoff or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in immediately available funds.
The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business
Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day
unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant
to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension. 
 (f) Unless the
Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent
may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such
amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the daily average
Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this
paragraph shall be conclusive in the absence of manifest error. If such Lender’s share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days of such Borrowing Date, the Administrative
Agent shall be entitled to recover such amount with interest thereon at the rate per annum applicable to ABR Loans under the relevant Facility, on demand, from the Borrower. 
  

 46 







 (g) Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date
of any payment being made hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required
to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days of such required date,
the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average
Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower. 
 (h) If and whenever any Event of Default has occurred and is continuing, unless this Agreement expressly provides that such payment or amount shall be allocated to a particular Lender or to the Lenders under a particular Facility, the
Administrative Agent shall apply all payments made by or on behalf of the Borrower or any Guarantor and all or any part of Proceeds (as defined in the Security Documents) constituting Collateral in payment of the Obligations in the following order:
first, to unpaid and unreimbursed costs, expenses and fees of the Administrative Agent, in its capacity as such (including to reimburse ratably any other Lender (or its Affiliates) which has advanced any of the same to the Administrative
Agent), second, to the Administrative Agent, for application by it toward payment of all amounts then due and owing and remaining unpaid in respect of the Obligations, pro rata among the Lenders (or their Affiliates) according to the amount
of the Obligations then due and owing and remaining unpaid to the Lenders (or their Affiliates), and third, to the Administrative Agent, for application by it toward prepayment of the Obligations, pro rata among the Lenders (or their
Affiliates) according to the amount of the Obligations then held by the Lenders (or their Affiliates). Any balance of such Proceeds remaining after the Obligations have been paid in full and all commitments to extend credit under the Loan Documents
have terminated shall be paid over to the Borrower or to whomsoever may be lawfully entitled to receive the same. 
 2.16 Requirements of
Law. 
 (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by
any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the Closing Date: 
 (i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any Application or
any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.17 and changes in the rate of tax on the overall net income of such Lender);

  

 47 







 (ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory
loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise
included in the determination of the Eurodollar Rate hereunder; or 
 (iii) shall impose on such Lender any other condition;

 and the result of any of the foregoing is to increase the cost to such Lender, by an amount that such Lender deems to be material, of
making, converting into, continuing or maintaining Eurodollar Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such
Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this paragraph, it shall promptly
notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled. 
 (b) If any Lender
shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or
directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the Closing Date shall have the effect of reducing the rate of return on such Lender’s or such corporation’s
capital as a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into
consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the
Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction; provided that the Borrower shall not be required to compensate a
Lender pursuant to this paragraph for any amounts incurred more than six months prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; and provided, further, that, if
the circumstances giving rise to such claim have a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect. 
 (c) A certificate, setting forth a reasonably detailed explanation as to the reason for any additional amounts payable pursuant to this Section, submitted by any Lender to the Borrower (with a copy to the
Administrative Agent) shall be conclusive in the absence of manifest error. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable
hereunder. 
  

 48 







 2.17 Taxes. 
 (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies,
imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed
on the Administrative Agent or any Lender as a result of a present or former connection between the Administrative Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other
Loan Document). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or Other Taxes are required to be withheld from any amounts payable to the Administrative
Agent or any Lender hereunder, (i) the amounts so payable to the Administrative Agent or such Lender shall be increased as necessary so that after making all required deductions and withholdings (including deductions and withholdings applicable
to additional sums payable under this Section 2.17), the Administrative Agent or such Lender, as the case may be, receives an amount equal to the sum it would have received had no such deduction or withholdings been made, (ii) the Borrower
shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority; provided, however, that the Borrower shall not be required to increase any such amounts payable to the
Administrative Agent or any Lender with respect to any Non-Excluded Taxes (x) that are attributable to the Administrative Agent’s or such Lender’s failure to comply with the requirements of paragraph (d) or (e) of this
Section 2.17 or (y) that are United States withholding taxes imposed on amounts payable to the Administrative Agent or such Lender at the time the Lender becomes a party to this Agreement (or designates a new lending office), except to the
extent that the Administrative Agent or such Lender’s assignor (if any) was entitled, pursuant to this paragraph, at the time of assignment, to receive additional amounts from the Borrower with respect to such Non-Excluded Taxes. 
 (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 
 (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the
Administrative Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof or other evidence of such payment reasonably
satisfactory to the Administrative Agent. If the Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate Governmental Authority or fails to remit to the Administrative Agent the required receipts or other required
documentary evidence, the Borrower shall indemnify the Administrative Agent and the Lenders for any Non-Excluded Taxes or Other Taxes paid by the Lenders or the Administrative Agent (whether or not such Non-Excluded Taxes or Other Taxes were
correctly or legally imposed or 

  

 49 







 
asserted by the relevant Governmental Authority), and any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any
Lender as a result of any such failure. 
 (d) Each Lender (or Transferee) that is not a “U.S. Person” as defined in
Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased)
two copies of fully-completed and executed originals of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of
the Code with respect to payments of “portfolio interest”, a statement substantially in the form of Exhibit H and a copy of a fully completed and executed original of U.S. Internal Revenue Service Form W-8BEN, or any subsequent versions
thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan
Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement or designates a new lending office (or, in the case of any Participant, on or before the date such Participant purchases the
related participation). In addition, each Non-U.S. Lender shall deliver copies of updated, fully-completed and executed originals of such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender.
Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer legally able to deliver any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing
authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver. 
 (e) If the Administrative Agent or any Lender receives a refund in respect of any amounts paid by the Borrower pursuant to this Section 2.17, which
refund in the sole reasonable judgment of such Administrative Agent or such Lender is allocable to such payment, it shall pay the amount of such refund to the Borrower, net of all out-of-pocket expenses of the Administrative Agent or such Lender;
provided, however, that the Borrower, upon the request of such Lender or the Administrative Agent, agrees to repay the amount paid over to the Borrower to the Administrative Agent or such Lender in the event such Administrative Agent
or the Lender is required to repay such refund. Nothing contained herein shall interfere with the right of the Administrative Agent or any Lender to arrange its tax affairs in whatever manner it deems fit nor oblige the Administrative Agent or any
Lender to apply for any refund or to disclose any information relating to its affairs or any computations in respect thereof. 
 (f) The
agreements in this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder. 
 2.18 Indemnity. The Borrower agrees to indemnify each Lender and to hold each Lender harmless from any loss or expense that such Lender sustains or incurs as a 

  

 50 







 
consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a
notice (or is deemed to have given notice) requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment of or conversion from Eurodollar Loans after the Borrower has given a
notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount
equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or
continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans
provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank eurodollar market. A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error.
This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder. 
 2.19
Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.16 or 2.17(a) with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts
(subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event with the object of avoiding the consequences of such event; provided that such designation is made on terms
that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage; and provided, further, that nothing in this Section shall affect or postpone any of the
obligations of the Borrower or the rights of any Lender pursuant to Section 2.16 or 2.17(a). 
 2.20 Replacement of Lenders. The
Borrower shall be permitted to replace any Lender that (a) requests reimbursement for amounts owing pursuant to Section 2.16 or 2.17(a) or (b) defaults in its obligation to make Loans hereunder, with a replacement financial
institution; provided that (i) such replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) prior to any such replacement,
such Lender shall have taken no action under Section 2.19 so as to eliminate the continued need for payment of amounts owing pursuant to Section 2.16 or 2.17(a), (iv) the replacement financial institution shall purchase, at par, all
Loans and other amounts owing to such replaced Lender on or prior to the date of replacement, (v) the Borrower shall be liable to such replaced Lender under Section 2.18 if any Eurodollar Loan owing to such replaced Lender shall be
purchased other than on the last day of the Interest Period relating thereto, (vi) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to the Administrative Agent, (vii) the replaced Lender
shall be obligated to make such replacement in accordance with the provisions of Section 10.6 (provided that the Borrower shall be obligated to pay the registration and processing fee referred to therein), (viii) until such time as
such replacement shall be consummated, the Borrower shall pay all additional amounts (if any) required pursuant to Section 2.16 or 2.17(a), as the case may be, and (ix) any such replacement 

  

 51 







 
shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

 2.21 Evidence of Debt. (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing
indebtedness of the Borrower to such Lender resulting from each Loan of such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement. 
 (b) The Administrative Agent, on behalf of the Borrower, shall maintain the Register pursuant to Section 10.6, and a subaccount therein for each
applicable Lender, in which shall be recorded (i) the amount of each Loan made to such Lender hereunder, the Type of such Loan and each Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to
become due and payable from the Borrower to such Lender hereunder and (iii) both the amount of any sum received by the Administrative Agent (or, in the case of an assignment not required to be recorded in the Register in accordance with the
provisions of Section 10.6, the assigning Lender) hereunder from the Borrower and such Lender’s share thereof. 
 (c) The entries
made in the Register shall, to the extent permitted by applicable law and absent manifest error, be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the
failure of any Lender or the Administrative Agent to maintain the Register or any such account, or any error therein, shall not in any manner affect the obligation of the Borrower to repay (with applicable interest) the Loans made to the Borrower by
such Lender in accordance with the terms of this Agreement. 
 (d) The Borrower agrees that, upon the request to the Administrative Agent by
any Lender, the Borrower will execute and deliver to such Lender a promissory note of the Borrower evidencing any Term Loans, Revolving Loans or Swingline Loans, as the case may be, of such Lender, substantially in the forms of Exhibit K-1, K-2 or
K-3, respectively, with appropriate insertions as to date and principal amount. 
 2.22 Illegality. Notwithstanding any other
provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the
commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert ABR Loans to Eurodollar Loans shall forthwith be canceled and (b) such Lender’s Loans then outstanding as Eurodollar Loans, if any,
shall be converted automatically to ABR Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day
which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 2.18. 
 2.23 Term Loans. 
  

 52 







 (a) Borrower Request. At any time and from time to time prior to the later of (x) the
Revolving Termination Date and (y) the latest final maturity date with respect to any outstanding Term Loans, the Borrower may by written notice to the Administrative Agent elect to request the establishment of one or more new Term Loan
Commitments; provided that the aggregate principal amount of Loans made pursuant to any Term Loan Commitment (“Term Loans”) shall not exceed $700,000,000 and each tranche of Term Loans shall be in minimum increments of
$50,000,000. Each such notice shall specify (i) the date (each, a “Term Loan Effective Date”) on which the Borrower proposes that the Term Loan Commitments shall be effective, which shall be a date not less than 3 Business Days
after the date on which such notice is delivered to the Administrative Agent (or such other date as shall be set forth in the applicable Term Loan Joinder), (ii) the identity of each Person (which, if not a Lender, an Approved Fund or an
Affiliate of a Lender, shall be reasonably satisfactory to the Administrative Agent and shall become a Lender under this Agreement pursuant to a Term Loan Joinder) to whom the Borrower proposes any portion of such Term Loan Commitment be allocated
and the amounts of such allocations and (iii) the terms and provisions of the Term Loans that will be made pursuant to such Term Loan Commitment; provided that any existing Lender approached to provide all or a portion of the Term Loan
Commitment may elect or decline, in its sole discretion, to provide such Term Loan Commitment. 
 (b) Conditions. A Term Loan
Commitment shall become effective, as of the applicable Term Loan Effective Date; provided that: 
 (i) each of the
conditions set forth in Section 5.2 shall be satisfied; 
 (ii) after giving pro forma effect to the Term Loans to be
borrowed on such Term Loan Effective Date and any change in Consolidated Adjusted EBITDA and any increase in Indebtedness, in each case resulting from the consummation of any Investment made concurrently with such borrowing, as of the last day of
the most recently completed fiscal quarter for which financial statements were required to be delivered pursuant to Section 6.1, the Borrower shall be in compliance with each of the covenants set forth in Section 7.1; 
 (iii) the Loan Parties shall deliver or cause to be delivered any legal opinions or other documents reasonably requested by the
Administrative Agent in connection with any such transaction, including, without limitation, a reaffirmation agreement in a form reasonably acceptable to the Administrative Agent; and 
 (iv) the Global Signal Acquisition shall have been consummated. 
  

 53 







 (c) Terms of Term Loans and Term Loan Commitments. The Term Loan Commitments shall be effected by
a joinder agreement (the “Term Loan Joinder”) executed by the Borrower, the Administrative Agent and each existing Lender and other Person making such Term Loan Commitment, in form and substance satisfactory to each of them. The
Term Loan Joinder 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 opinion of the Administrative Agent, to effect the provisions of this
Section 2.23. The terms and provisions of the Term Loans shall be as set forth herein or in the applicable Term Loan Joinder. 
 (d)
Making of Term Loans. On any Term Loan Effective Date on which Term Loan Commitments are effective, subject to the satisfaction of the foregoing terms and conditions, each Lender with any such Term Loan Commitment shall make a Term Loan to
the Borrower in an amount equal to its Term Loan Commitment. 
 (e) Equal and Ratable Benefit. The Term Loans and Term Loan
Commitments established pursuant to this Section 2.23 shall constitute Loans and Commitments under, and shall be entitled to all the benefits afforded by, this Agreement and the other Loan Documents, and shall, without limiting the foregoing,
benefit equally and ratably with the Obligations from the Guaranty and security interests created by the Security Documents. The Loan Parties shall take any actions reasonably required by the Administrative Agent to ensure and/or demonstrate that
the Lien and security interests granted by the Security Documents continue to be perfected under the UCC or otherwise after giving effect to the establishment of any such class of Term Loans or any such Term Loan Commitments. 
 SECTION 3. LETTERS OF CREDIT 
 3.1 L/C Commitment.

 (a) Subject to the terms and conditions hereof, each Issuing Lender, in reliance on the agreements of the other Revolving Lenders set forth
in Section 3.4(a), agrees to issue letters of credit (“Letters of Credit”) for the account of the Borrower on any Business Day during the Revolving Commitment Period in such form as may be approved from time to time by such
Issuing Lender; provided that no Issuing Lender shall have an obligation to issue (and no Revolving Lenders shall have an obligation to participate in) any Letter of Credit if, after giving effect to such issuance, (i) the L/C
Obligations would exceed the L/C Commitment or (ii) the aggregate amount of the Available Revolving Commitments would be less than zero. Each Letter of Credit shall (i) be denominated in Dollars, (ii) have a face amount of at least
$100,000 (unless otherwise agreed by the relevant Issuing Lender) and (iii) expire no later than the date that is five Business Days prior to the Revolving Termination Date. 
 (b) No Issuing Lender shall at any time be obligated to issue any Letter of Credit hereunder if such issuance would conflict with, or cause such Issuing
Lender or any L/C Participant to exceed any limits imposed by, any applicable Requirement of Law. 
  

 54 







 3.2 Procedure for Issuance of Letter of Credit. The Borrower may from time to time request that
any Issuing Lender issue a Letter of Credit by delivering to such Issuing Lender at its address for notices specified herein an Application therefor, completed to the satisfaction of such Issuing Lender, and such other certificates, documents and
other papers and information as such Issuing Lender may request. Upon receipt of any Application, the relevant Issuing Lender will process such Application and the certificates, documents and other papers and information delivered to it in
connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby (but in no event shall such Issuing Lender be required to issue any Letter of Credit earlier than three Business Days
after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed to
by such Issuing Lender and the Borrower. The relevant Issuing Lender shall furnish a copy of such Letter of Credit to the Borrower promptly following the issuance thereof. The relevant Issuing Lender shall promptly furnish to the Administrative
Agent, which shall in turn promptly furnish to the Lenders, notice of the issuance of each Letter of Credit (including the amount thereof). 
 3.3 Fees and Other Charges. 
 (a) The Borrower will pay a fee on all outstanding Letters of Credit at a per annum rate equal
to the Applicable Margin then in effect with respect to Eurodollar Loans under the Revolving Facility, shared ratably among the Revolving Lenders and payable quarterly in arrears on each L/C Fee Payment Date after the issuance date. In addition, the
Borrower shall pay to the relevant Issuing Lender for its own account a fronting fee of 0.25% per annum on the face amount of each Letter of Credit, payable quarterly in arrears on each L/C Fee Payment Date after the Issuance Date. 

(b) In addition to the foregoing fees, the Borrower shall pay or reimburse the relevant Issuing Lender for such normal and customary costs and
expenses as are incurred or charged by such Issuing Lender in issuing, negotiating, effecting payment under, amending or otherwise administering any Letter of Credit. 
 3.4 L/C Participations. 
 (a) Each Issuing Lender irrevocably agrees to grant and hereby grants to
each L/C Participant, and, to induce the Issuing Lenders to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from each Issuing Lender, on the terms and conditions set
forth below, for such L/C Participant’s own account and risk an undivided interest equal to such L/C Participant’s Revolving Percentage in each Issuing Lender’s obligations and rights under and in respect of each Letter of Credit
issued by it hereunder and the amount of each draft paid by such Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably agrees with each Issuing Lender that, if a draft is paid under any Letter of Credit for which such
Issuing Lender is not reimbursed in full by the Borrower in accordance with the terms of this Agreement, such L/C Participant shall pay to such Issuing Lender upon demand at such Issuing Lender’s address for notices specified herein an 

  

 55 







 
amount equal to such L/C Participant’s Revolving Percentage of the amount of such draft, or any part thereof, that is not so reimbursed. Each L/C
Participant’s obligation to pay such amount shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such L/C Participant may have
against the Issuing Lender, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or continuance of a Default or an Event of Default or the failure to satisfy any of the other conditions specified in Section 5,
(iii) any adverse change in the condition (financial or otherwise) of the Borrower, (iv) any breach of this Agreement or any other Loan Document by the Borrower, any other Loan Party or any other L/C Participant or (v) any other
circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. 
 (b) If any amount required to be paid by any
L/C Participant to any Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by such Issuing Lender under any Letter of Credit is paid to such Issuing Lender within three Business Days after the
date such payment is due, such L/C Participant shall pay to such Issuing Lender on demand an amount equal to the product of (i) such amount, times (ii) the daily average Federal Funds Effective Rate during the period from and including the
date such payment is required to the date on which such payment is immediately available to such Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is
360. If any such amount required to be paid by any L/C Participant pursuant to Section 3.4(a) is not made available to the relevant Issuing Lender by such L/C Participant within three Business Days after the date such payment is due, such
Issuing Lender shall be entitled to recover from such L/C Participant, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to ABR Loans under the Revolving Facility. A certificate of the
relevant Issuing Lender submitted to any L/C Participant with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error. 
 (c) Whenever, at any time after the relevant Issuing Lender has made payment under any Letter of Credit and has received from any L/C Participant its pro rata share of such payment in accordance with
Section 3.4(a), such Issuing Lender receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of collateral applied thereto by such Issuing Lender), or any payment of interest on
account thereof, such Issuing Lender will distribute to such L/C Participant its pro rata share thereof; provided, however, that in the event that any such payment received by such Issuing Lender shall be required to be returned by
such Issuing Lender, such L/C Participant shall return to such Issuing Lender the portion thereof previously distributed by such Issuing Lender to it. 
 3.5 Reimbursement Obligation of the Borrower. The Borrower agrees to reimburse the relevant Issuing Lender on each date next succeeding the date on which such Issuing Lender notifies the Borrower of the date
and amount of a draft presented under any Letter of Credit and paid by such Issuing Lender for the amount of (a) such draft so paid and (b) any taxes, fees, charges or other costs or expenses incurred by such Issuing Lender in connection
with such payment. Each such payment shall be made to the relevant Issuing Lender at its address for notices specified herein in lawful money of the United States and in immediately 

  

 56 







 
available funds. Interest shall be payable on any and all amounts remaining unpaid by the Borrower under this Section from the date on which the relevant
draft is paid or the relevant costs or expenses are incurred, as the case may be, until payment in full at the rate set forth in (i) until the second Business Day following such date, Section 2.12(b) and (ii) thereafter,
Section 2.12(c). 
 3.6 Obligations Absolute. The Borrower’s obligations under this Section 3 shall be absolute and
unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that the Borrower may have or have had against any Issuing Lender, any beneficiary of a Letter of Credit or any other Person. The
Borrower also agrees with each Issuing Lender that no Issuing Lender shall be responsible for, and the Borrower’s Reimbursement Obligations under Section 3.5 shall not be affected by, among other things, the validity or genuineness of
documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such
Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee. No Issuing Lender shall be liable for any error, omission, interruption or delay in transmission,
dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the
gross negligence or willful misconduct of the relevant Issuing Lender. The Borrower agrees that any action taken or omitted by any Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the
absence of gross negligence or willful misconduct and in accordance with the standards of care specified in the Uniform Commercial Code of the State of New York, shall be binding on the Borrower and shall not result in any liability of any Issuing
Lender to the Borrower. 
 3.7 Letter of Credit Payments. If any draft shall be presented for payment under any Letter of Credit, the
relevant Issuing Lender shall promptly notify the Borrower of the date and amount thereof. The responsibility of each Issuing Lender to the Borrower in connection with any draft presented for payment under any Letter of Credit shall, in addition to
any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are substantially in conformity
with such Letter of Credit. 
 3.8 Applications. To the extent that any provision of any Application related to any Letter of Credit
is inconsistent with the provisions of this Section 3, the provisions of this Section 3 shall apply. 
 SECTION 4. REPRESENTATIONS AND WARRANTIES

 To induce the Administrative Agent and the Lenders to enter into this Agreement and to make the Loans and issue or participate in the
Letters of Credit, Holdings and the Borrower hereby jointly and severally represent and warrant to the Administrative Agent and each Lender that:

foregoing. Each of the Pro Forma Balance Sheets has been prepared based on the best information available to the Borrower as of the date of delivery thereof, and presents fairly on a pro forma basis the estimated financial position of (i) the

Subsidiaries) as at December 31, 2005, and the related consolidated statements of income and of cash flows for the fiscal year ended on such date, reported on by and accompanied by an unqualified report from KPMG, LLP, present fairly the
consolidated financial condition of Holdings and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the fiscal year then ended. The unaudited consolidated financial statements of
Holdings and its Subsidiaries as at March 31, 2006, June 30, 2006 and September 30, 2006, and the related unaudited consolidated statements of income and cash flows for the three-month, six-month or nine-month period (as

ended (subject to the absence of footnotes and normal year-end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the
periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). Holdings and its Subsidiaries do not have any material Contingent Obligations, contingent liabilities and liabilities for taxes, or any long-term

referred to in this paragraph or not otherwise permitted pursuant to the terms hereof. During the period from December 31, 2005 to and including the Closing Date there has been no Disposition by Holdings or any of its Subsidiaries of any
material part of its business or property. 
 4.2 No Change. Since December 31, 2005, there has been no development or event that
has had or could reasonably be expected to have a Material Adverse Effect.

property or the conduct of its business requires such qualification except to the extent that the failure to be so qualified and in good standing could not, in the aggregate, reasonably be expected to have a Material Adverse Effect and (d) is
in compliance with all Requirements of Law except to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect. 
 4.4 Corporate Power; Authorization; Enforceable Obligations. Each Loan Party has the corporate power and authority, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and, in the case of the Borrower, to obtain extensions of credit hereunder. Each Loan Party has taken all necessary corporate action to authorize the execution, delivery and performance
of the Loan Documents to which it is a party and, in the case of the Borrower, to authorize the extensions of credit on the terms and conditions of this Agreement. No material consent or authorization of, filing with, notice to or other act by or in
respect of, any Governmental Authority (including without limitation, the FCC, the FAA or any other Licensing Authority) or any other Person is required in connection with the extensions of credit hereunder or with the execution, delivery,
performance, validity or enforceability of this Agreement or any of the Loan Documents, except (i) consents, authorizations, filings and notices described in Schedule 4.4, which consents, authorizations, filings and notices have been obtained
or made and are in full force and effect and (ii) the filings referred to in Section 4.19. Each Loan Document has been duly executed and delivered on behalf of each Loan Party party thereto. This Agreement constitutes, and each other Loan
Document upon execution will constitute, a legal, valid and binding obligation of each Loan Party party thereto, enforceable against each such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). 
 4.5 No Legal Bar. The execution, delivery and performance of this Agreement and the other Loan Documents, the issuance of Letters of Credit, the
borrowings hereunder and the use of the proceeds thereof will not violate any Governing Document, Requirement of Law (including any rule, regulation or policy of the FCC, the FAA or any other Licensing Authority), any Contractual Obligation of
Holdings, the Borrower or any of their respective Subsidiaries and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual
Obligation (other than the Liens created by the Security Documents). 
 4.6 Litigation. No litigation, investigation or proceeding of
or before any arbitrator or Governmental Authority is pending or, to the knowledge of Holdings or the Borrower, threatened by or against Holdings, the Borrower or any of their respective Subsidiaries or against any of their respective Licenses,

in title. 
 4.9 Intellectual Property. Holdings, the Borrower and each of their respective Subsidiaries owns, or is licensed to use,
all Intellectual Property necessary for the conduct of its business as currently conducted. No material claim has been asserted and is pending by any Person challenging or questioning the use of any Intellectual Property or the validity or
effectiveness of any Intellectual Property, nor does Holdings or the Borrower know of any valid basis for any such claim. The use of Intellectual Property by Holdings, the Borrower and their respective Subsidiaries does not infringe on the rights of
any Person in any material respect.

or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all material taxes shown to be due and payable on said returns or on any assessments made against it or any of its property and all

which reserves in conformity with GAAP have been provided on the books of Holdings, the Borrower or their respective Subsidiaries, as the case may be); no tax Lien has been filed, and, to the knowledge of Holdings and the Borrower, no claim is being

a Material Adverse Effect: 
 (a) the facilities and properties owned, leased or operated by Holdings, the Borrower or any of their respective

 4.18 Accuracy of Information, etc. No statement or information
contained in this Agreement, any other Loan Document, any confidential information memorandum distributed to any Lender or prospective Lender or any other document, certificate or statement furnished by or on behalf of any Loan Party to the
Administrative Agent or the Lenders, or any of them, for use in connection with the transactions contemplated by this Agreement or the other Loan Documents, contained as of the date such statement, information, document or certificate was so
furnished, any untrue statement of a material fact or omitted to state a material fact necessary to make the statements contained herein or therein not misleading. The projections and pro forma financial information contained in the materials
referenced above are based upon good faith estimates and assumptions believed by management of the Borrower to be reasonable at the time made, it being recognized by the Lenders that such financial information as it relates 

  

 62 







 
to future events is not to be viewed as fact and that actual results during the period or periods covered by such financial information may differ from the
projected results set forth therein by a material amount. 
 4.19 Security Interests. (a) Each of the Security Documents is
effective to create in favor of the Administrative Agent, for the benefit of the Lenders, a legal, valid and enforceable security interest in the Collateral described therein and proceeds thereof. In the case of the Stock Interests (as defined in
the Pledge Agreement) described in the Pledge Agreement, when stock certificates, partnership interest certificates or limited liability company interest certificates representing such Stock Interests are delivered to the Administrative Agent, and
in the case of the other Collateral described in the Security Documents, when financing statements and other filings specified on Schedule 4.19 in appropriate form are filed in the offices specified on Schedule 4.19 and the Control Agreements are
executed and delivered by all parties thereto, each of the Security Documents shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of the Loan Parties in such Collateral and the proceeds thereof, as
security for the Obligations (as defined in each Security Document), in each case prior and superior in right to any other Person (other than Liens permitted by Section 7.3). 
 4.20 Solvency. Each Loan Party is, and after giving effect to the incurrence of all Indebtedness and obligations being incurred in connection
herewith will be and will continue to be, Solvent. 
 4.21 Licenses and Registrations. Holdings and each of its Subsidiaries hold all
of the material Licenses that are necessary for the lawful ownership, construction, management or operation of all Tower Sites or of the business of the Holdings and its Subsidiaries in the manner and to the full extent they are currently owned,
constructed, managed and operated. All of the material Licenses of Holdings and its Subsidiaries have been duly and validly issued to and are legally held by the Holdings or such Subsidiary and are in full force and effect without condition except
those of general application. Except as could not reasonably be expected to have a Material Adverse Effect, such Licenses have been issued in compliance with all applicable laws and regulations, are legally binding and enforceable in accordance with
their terms and are in good standing. Neither Holdings nor any of its Subsidiaries know of any facts or conditions that would constitute grounds for any Licensing Authority to deny any pending material application for a License with respect to any
Material Towers, to suspend, revoke, materially adversely modify or annul any License with respect to any Material Towers or to impose a material financial penalty on Holdings or any Subsidiary. All Material Towers that are required to be registered
with the FCC have either been so registered or are in the process of being registered.

Loan Agreement; Global Signal 2006 Loan Agreement; Holdings Securities Filings. 
 (a) The execution, delivery and performance by each
Loan Party of this Agreement and the Loan Documents and all actions and transactions contemplated hereby and thereby will not violate, be in conflict with, result in a breach of or constitute (with due notice or lapse of time or both) a default in
any material respect under the Tower Notes Indenture, any

 (b) Upon and after the consummation of the Global Signal Acquisition, the execution, delivery and performance by each Loan Party of this Agreement and
the Loan Documents and all actions and transactions contemplated hereby and thereby will not violate, be in conflict with, result in a breach of or constitute (with due notice or lapse of time or both) a default in any material respect under the
Global Signal 2004 Loan Agreement or the Global Signal 2006 Loan Agreement. 
 (c) The Borrower has provided to the Administrative Agent
complete and correct copies of each of the Tower Notes Indenture Documents. No default or event of default has occurred and is continuing under any of the Tower Notes Indenture Documents, and each Tower Notes Indenture Document is in full force and
effect. No Tower Notes Indenture Document has been amended or modified except as expressly permitted pursuant to Section 7.8(d). 
 (d)
Upon the consummation of the Global Signal Acquisition, the Borrower has provided to the Administrative Agent complete and correct copies of each of the Global Signal Loan Documents. Upon and after the consummation of the Global Signal Acquisition,

Global Signal Loan Document has been amended or modified except as expressly permitted pursuant to Section 7.8(d).

misleading.

 then, and in any such event, (A) if such event is an Event of Default specified in clause (i) or (ii) of paragraph (f) above with respect to the

Borrower and the other Loan Parties hereunder and under the other Loan Documents shall have been paid in full, the balance, if any, in such cash collateral account shall be returned to the Borrower (or such other Person as may be lawfully entitled
thereto). Except as expressly provided above in 

  

 94 







 
this Section, presentment, demand, protest and all other notices of any kind are hereby expressly waived by the Borrower. 
 SECTION 9. THE ADMINISTRATIVE AGENT 
 9.1 Appointment.
Each Lender hereby irrevocably designates and appoints the Administrative Agent as the agent of such Lender under this Agreement and the other Loan Documents, and each such Lender irrevocably authorizes the Administrative Agent, in such capacity, to
take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent by the terms of this Agreement and the
other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, the Administrative Agent shall not have any duties or responsibilities, except
those expressly set forth herein, or any fiduciary relationship with any Lender, 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 Agent. 
 9.2 Delegation of Duties. The Administrative Agent may execute any of its duties under this
Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or
misconduct of the Administrative Agent or attorneys in-fact selected by it with reasonable care. 
 9.3 Exculpatory Provisions.
Neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with
this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from its or such Person’s own gross negligence or
willful misconduct) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in
any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of any Loan Party a party thereto to perform its obligations hereunder or thereunder. The Administrative Agent shall not be under any
obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan
Party. 
 9.4 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely, and shall be fully protected in
relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to Holdings or the Borrower), independent accountants and other 

  

 95 







 
experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any promissory note evidencing Loans as the owner
thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, (a) the Majority Facility Lenders with respect to the Revolving Facility or
(b) all Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The
Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement,
(a) the Majority Facility Lenders with respect to the Revolving Facility or (b) all Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the
Loans. 
 9.5 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any
Default or Event of Default hereunder unless the Administrative Agent has received notice from a Lender, Holdings or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice
of default”. In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default
as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders); provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall
not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders. 
 9.6 Non-Reliance on Administrative Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or Affiliates have made any representations or warranties to it and that no act by the Administrative Agent hereafter taken, including any review of the affairs of a Loan Party or any
Affiliate of a Loan Party, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the
Administrative Agent or any other Lender, bookrunner or arranger and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other
condition and creditworthiness of the Loan Parties and their Affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement
and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their Affiliates. Except for
notices, reports and other documents expressly required 

  

 96 







 
to be furnished to the Lenders by the Administrative Agent hereunder or under the other Loan Documents, the Administrative Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of any Loan Party or any Affiliate of a Loan Party that may
come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates. 
 9.7 Indemnification. The Lenders agree to indemnify the Administrative Agent in its capacity as such (to the extent not reimbursed by Holdings or the Borrower and without limiting the obligation of Holdings or the Borrower to do so),
ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments shall have terminated and
the Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans) be imposed on, incurred by or asserted against the Administrative Agent in any way relating to or arising out of, the
Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Administrative Agent under or in
connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are
found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the Administrative Agent’s gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and
all other amounts payable hereunder. 
 9.8 Administrative Agent in Its Individual Capacity. The Administrative Agent and its
Affiliates may make loans to, accept deposits from and generally engage in any kind of business with any Loan Party as though the Administrative Agent were not the Administrative Agent. With respect to its Loans made or renewed by it and with
respect to any Letter of Credit issued or participated in by it, the Administrative Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not the
Administrative Agent, and the terms “Lender” and “Lenders” shall include the Administrative Agent in its individual capacity. 
 9.9 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 30 days’ notice to the Lenders and the Borrower. If the Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 8(a) or Section 8(f) with
respect to the Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of
the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall
be terminated, without any other or further act 

  

 97 







 
or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has
accepted appointment as Administrative Agent by the date that is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and
the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. After any retiring Administrative Agent’s resignation
as Administrative Agent, the provisions of this Section 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents. 
 9.10 Other Agents; Lead Arrangers. None of the Lenders identified on the cover page or signature pages of this Agreement as a
“bookrunner” or “lead arranger” shall have any rights, powers, obligations, liabilities, responsibilities or duties under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of
the Lenders so identified shall have or be deemed to have any fiduciary relationship with any Lender. 
 SECTION 10. MISCELLANEOUS 
 10.1 Amendments and Waivers. Except as reasonably necessary to effect Term Loans pursuant to Section 2.23 of this Agreement, neither this
Agreement, any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 10.1. The Required Lenders and each Loan Party party to the relevant Loan
Document may, or, with the written consent of the Required Lenders, the Administrative Agent and each Loan Party party to the relevant Loan Document may, from time to time, (a) enter into written amendments, supplements or modifications hereto

scheduled date of maturity of any Loan or Reimbursement Obligation, extend the scheduled date of any amortization payment in respect of any Term Loan, reduce the stated rate of any interest, fee or other amount payable hereunder (except (x) in
connection with the waiver of applicability of any post-default increase in interest rates, which waiver shall be effective with the consent of the Majority Facility Lenders of each adversely affected Facility and (y) that any amendment or
modification of defined terms used in the financial covenants in this Agreement shall not constitute a reduction in the rate of interest or fees for purposes of this clause (i)) or extend the scheduled date of any payment thereof, or increase the
amount or extend the expiration date of any Lender’s Commitment, in each case without the written consent of each Lender directly affected thereby; (ii) eliminate or reduce the voting or consent rights of any Lender under this
Section 10.1 or any other Section of this Agreement without the written consent of such Lender; (iii) reduce any percentage specified in the definition of Required Lenders (it being understood that, with the consent of the Required

Guarantors from their obligations hereunder, in each case without the written consent of all Lenders, or reduce any percentage specified in the definition of Majority Facility Lender without the consent of each Lender under the affected Facility or
reduce any Lender’s Revolving Percentage without the consent of such Lender; (iv) amend, modify or waive any condition precedent to any extension of credit under any Facility set forth in Section 5.2 (including in connection with any

Default under Section 8(a) shall require the written consent of all Lenders; (v) reduce the amount, or change the order of application, of Net Cash Proceeds or Excess Cash Flow required to be applied to prepay Loans under this Agreement

those rights of the Revolving Lenders, in each case without the consent of the Majority Facility Lenders under the Facility so adversely affected; or (xii) amend any provision of Section 10.7(a) without the consent of each Lender. Any such
waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the Administrative Agent and all future holders of the Loans. In the case of any waiver,
the Loan Parties, the Lenders and the Administrative Agent shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing,
but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. 
 10.2

right, remedy, power or privilege hereunder or under the other Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise

reasonable out-of-pocket costs and expenses incurred in connection with the development, preparation and execution of, and any 

  

 100 







 
amendment, supplement or modification to, this Agreement and the other Loan Documents and any other documents prepared in connection herewith or therewith,
and the consummation and administration of the transactions contemplated hereby and thereby, including the reasonable fees and disbursements of counsel to the Administrative Agent and filing and recording fees and expenses, with statements with
respect to the foregoing to be submitted to the Borrower prior to the Closing Date (in the case of amounts to be paid on the Closing Date) and from time to time thereafter on a quarterly basis or such other periodic basis as the Administrative Agent
shall deem appropriate, (b) to pay or reimburse each Lender and the Administrative Agent for all its costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents and
any such other documents, including the fees and disbursements of counsel to each Lender and of counsel to the Administrative Agent, (c) to pay, indemnify, and hold each Lender and the Administrative Agent harmless from, any and all recording
and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, that may be payable or determined to be payable in connection with the execution and delivery of, or
consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and
(d) to pay, indemnify, and hold each Lender and the Administrative Agent and their respective officers, directors, employees, Affiliates, agents, trustees and investment advisers and controlling persons (each, an “Indemnitee”)
harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Agreement, the other Loan Documents and any such other documents, including any of the foregoing relating to the Commitments, use of proceeds of the Loans or the violation of, noncompliance with or liability
under, any Environmental Law applicable to the operations of Holdings, the Borrower, any of their respective Subsidiaries or any of their properties and the reasonable fees and expenses of legal counsel in connection with claims, actions or
proceedings by any Indemnitee against any Loan Party under any Loan Document (all the foregoing in this clause (d), collectively, the “Indemnified Liabilities”); provided that the Borrower shall have no obligation hereunder
to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful
misconduct of such Indemnitee. Without limiting the foregoing, and to the extent permitted by applicable law, the Borrower agrees not to assert and to cause the Subsidiaries not to assert, and hereby waives and agrees to cause the Subsidiaries to
waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that
any of them might have by statute or otherwise against any Indemnitee. All amounts due under this Section 10.5 shall be payable not later than 10 days after written demand therefor. Statements payable by the Borrower pursuant to this
Section 10.5 shall be submitted to Treasurer and General Counsel (Telephone No. (713) 570-3000) (Telecopy No. (713) 570-3150), at the address of the Borrower set forth in Section 10.2, or to such other Person or address as may be
hereafter designated by the Borrower in a written notice to the Administrative Agent. The agreements in this Section 10.5 shall survive the termination of this Agreement and the repayment of the Loans and all other amounts payable hereunder.

  

 101 







 It is understood and agreed that, to the extent not precluded by a conflict of interest, each Indemnitee
shall endeavor to reasonably work cooperatively with the Borrower with a view to minimizing the legal and other expenses associated with any defense and any potential settlement or judgment. To the extent reasonably practicable and not
disadvantageous to any Indemnitee, it is anticipated that a single counsel will be used. Settlement of any claim or litigation involving any material indemnified amount will require the approval of the Borrower (not to be unreasonably withheld).

 10.6 Successors and Assigns; Participations and Assignments. 
 (a) This Agreement shall be binding upon and inure to the benefit of Holdings, the Borrower, the Subsidiary Guarantors, the Lenders, the Administrative
Agent, all future holders of the Loans and their respective successors and assigns, except that (i) the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of each Lender
and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. 
 (b)
(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees (each, an “Assignee”) all or a portion of its rights and obligations under this Agreement (including all or a portion
of its Revolving Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld or delayed) of: 
 (A) the Borrower; provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a
Lender, an Approved Fund (as defined below) or, if an Event of Default has occurred and is continuing, any other Person; and 
 (B) the Administrative Agent; provided that no consent of the Administrative Agent shall be required for an assignment of (x) any Revolving Commitment to an assignee that is a Lender with a Revolving Commitment immediately prior
to giving effect to such assignment or (y) all or any portion of a Term Loan to a Lender, an Affiliate of a Lender or an Approved Fund. 
 (ii) Assignments shall be subject to the following additional conditions: 
 (A) except in the
case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Revolving Commitment or Loans under any Facility, the amount of the Revolving Commitment
or 

  

 102 







 
Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is
delivered to the Administrative Agent) shall not be less than $5,000,000, in the case of the Revolving Loans, or $1,000,000, in the case of the Term Loans, unless each of the Borrower and the Administrative Agent otherwise consent; provided that
(1) no such consent of the Borrower shall be required (x) if an Event of Default has occurred or (y) prior to the earlier of 30 days following the Closing Date or the date on which the Administrative Agent notifies the Borrower that
the Facilities have been syndicated and (2) such amounts shall be aggregated in respect of each Lender and its Affiliates or Approved Funds, if any; 
 (B) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; provided that only one such fee
shall be payable in the case of simultaneous assignments by or to related Approved Funds; and 
 (C) the Assignee, if it shall
not be a Lender, shall deliver to the Administrative Agent an administrative questionnaire and any tax forms required by Section 2.17(d) as well as all documentation and other information required by bank regulatory authorities under applicable
“know your customer” and anti-money laundering rules and regulations, including the Patriot Act, as reasonably requested by the Administrative Agent. 
 For the purposes of this Section 10.6, “Approved Fund” means any Person (other than a natural person) that is
engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course of its activities and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or
(c) an entity or an Affiliate of an entity that administers or manages a Lender. 
 (iii) Subject to acceptance and
recording thereof pursuant to paragraph (b)(iv) below, from and after the effective date specified in each Assignment and Assumption the Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and
Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement
(and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections
2.16, 2.17, 2.18 and 10.5). Any assignment or transfer by a Lender of rights or obligations under 

  

 103 







 
this Agreement that does not comply with this Section 10.6 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 (c) of this Section. 
 (iv) The Administrative Agent, acting
for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and
principal amount of the Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent,
the Issuing Lender and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Borrower and each Lender, at any reasonable time and from time to time upon reasonable prior notice. 
 (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an Assignee, the Assignee’s completed administrative questionnaire and any tax forms required by Section 2.17(d) (unless the
Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent
shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

 (c) (i) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other
entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans owing to it); provided that (A) such
Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the
Issuing Lender and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement 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 may provide that such Lender will not,
without the consent of the Participant, agree to any amendment, modification or waiver that (1) requires the consent of each Lender directly affected thereby pursuant to the proviso to the second sentence of Section 10.1 and
(2) directly affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.16, 2.17 and 2.18 to the same 

  

 104 







 
extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law,
each Participant also shall be entitled to the benefits of Section 10.7(b) as though it were a Lender; provided such Participant shall be subject to Section 10.7(a) as though it were a Lender. 
 (ii) A Participant shall not be entitled to receive any greater payment under Section 2.16 or 2.17 than the applicable Lender would
have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. Any Participant that would be a Non-U.S.
Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to the Participant and such Participant agrees, for the benefit of the Borrower, to comply with
Section 2.17(d) as though it were a Lender. 
 (d) Any Lender may, without the consent of the Borrower or the Administrative Agent, at
any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall
not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or Assignee for
such Lender as a party hereto. 
 (e) The Borrower, upon receipt of written notice from the relevant Lender, agrees to issue promissory notes
to any Lender requiring such notes to facilitate transactions of the type described in paragraph (d) above. 
 (f) Notwithstanding the
foregoing, any Conduit Lender may assign any or all of the Loans it may have funded hereunder to its designating Lender without the consent of the Borrower or the Administrative Agent and without regard to the limitations set forth in
Section 10.6(b). Each of Holdings, the Borrower, each Lender and the Administrative Agent hereby confirms that it will not institute against a Conduit Lender or join any other Person in instituting against a Conduit Lender any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceeding under any state bankruptcy or similar law, in connection with any obligations of such Conduit Lender under the Loan Documents, for one year and one day after the payment in full of
the latest maturing commercial paper note issued by such Conduit Lender; provided, however, that each Lender designating any Conduit Lender hereby agrees to indemnify, save and hold harmless each other party hereto for any loss, cost,
damage or expense arising out of its inability to institute such a proceeding against such Conduit Lender during such period of forbearance. Such indemnity shall survive the repayment of all Obligations and the termination of the Commitments.

 10.7 Adjustments; Set-off. 
  

 105 







 (a) Except to the extent that this Agreement expressly provides for payments to be allocated to a
particular Lender or to the Lenders under a particular Facility, if any Lender (a “Benefitted Lender”) shall, at any time after the Loans and other amounts payable hereunder shall immediately become due and payable pursuant to
Section 8, receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in
Section 8(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of the Obligations owing to such other Lender, such Benefitted Lender shall purchase for cash from the
other Lenders a participating interest in such portion of the Obligations owing to each such other Lender, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share
the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase
shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. 
 (b) In addition to
any rights and remedies of the Lenders provided by law, if an Event of Default shall have occurred and be continuing, each Lender shall have the right, without prior notice to Holdings or the Borrower, any such notice being expressly waived by
Holdings and the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by Holdings or the Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply
against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent,
matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of Holdings or the Borrower, as the case may be. Each Lender agrees promptly to notify the Borrower and the
Administrative Agent after any such setoff and application made by such Lender; provided that the failure to give such notice shall not affect the validity of such setoff and application. 
 10.8 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all
of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart
hereof. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent. 
 10.9 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 
 10.10 Integration. This Agreement and the other Loan Documents represent the entire agreement of Holdings, the Borrower, the Administrative Agent
and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, 

  

 106 







 
representations or warranties by the Administrative Agent or any Lender relative to the subject matter hereof not expressly set forth or referred to herein
or in the other Loan Documents. 
 10.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS
AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 
 10.12 Submission To

 (a) submits for itself and its
property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts
of the State of New York, the courts of the United States for the Southern District of New York, and appellate courts from any thereof; 
 (b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was
brought in an inconvenient court and agrees not to plead or claim the same; 
 (c) agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to Holdings or the Borrower, as the case may be at its address set forth in Section 10.2 or at
such other address of which the Administrative Agent shall have been notified pursuant thereto; 
 (d) agrees that nothing herein shall
affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and 
 (e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages. 
 10.13 Acknowledgements. Each of Holdings and the Borrower hereby acknowledges that: 
 (a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents; 
  

 107 







 (b) neither the Administrative Agent nor any Lender has any fiduciary relationship with or duty to
Holdings or the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent and Lenders, on one hand, and Holdings and the Borrower, on the other hand, in
connection herewith or therewith is solely that of debtor and creditor; and 
 (c) no joint venture is created hereby or by the other Loan
Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among Holdings, the Borrower and the Lenders. 
 10.14 Releases of Guarantees and Liens. 
 (a) Notwithstanding anything to the contrary contained herein or in any other Loan
Document, the Administrative Agent is hereby irrevocably authorized by each Lender (without requirement of consent of any Lender except as expressly required by Section 10.1) to take any action requested by the Borrower having the effect of
releasing any Collateral or Contingent Obligations (i) to the extent necessary to permit consummation of any transaction not inconsistent with any Loan Document or that has been consented to in accordance with Section 10.1 or
(ii) under the circumstances described in paragraph (b) below. 
 (b) At such time as the Loans, the Reimbursement Obligations and
the other Obligations under the Loan Documents (other than Obligations under or in respect of Swap Agreements) shall have been paid in full, the Commitments have been terminated, no Letters of Credit shall be outstanding, the Collateral shall be
released from the Liens created by the Security Documents, and the Security Documents and all obligations (other than those expressly stated to survive such termination) of the Administrative Agent and each Loan Party under the Security Documents
shall terminate, all without delivery of any instrument or performance of any act by any Person. 
 10.15 Confidentiality. 

(a) Each of the Administrative Agent and each Lender agrees to keep confidential all non-public information provided to it by any Loan Party pursuant
to this Agreement that is designated by such Loan Party as confidential; provided that nothing herein shall prevent the Administrative Agent or any Lender from disclosing any such information (a) to the Administrative Agent, any other
Lender, any Affiliate of any Lender or any Approved Fund, (b) to any (i) actual or prospective Transferee, (ii) Swap Agreement counterparty or (iii) direct or indirect contractual counterparty in swap agreements (or such
contractual counterparty’s professional advisor), in each case that agrees to comply with the provisions of this Section, (c) to its employees, directors, agents, attorneys, accountants and other professional advisors or those of any of
its Affiliates, (d) upon the request or demand of any Governmental Authority, (e) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any Requirement of Law, (f) if
requested or required to do so in connection with any litigation or similar proceeding, (g) that has been publicly disclosed (other than as a 

  

 108 







 
result of a breach of this Section), (h) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized
rating agency that requires access to information about a Lender’s investment portfolio in connection with ratings issued with respect to such Lender, or (i) in connection with the exercise of any remedy hereunder or under any other Loan
Document. 
 (b) Notwithstanding anything herein to the contrary, each party hereto (and any employee, representative or other agent of each
party hereto) may disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and the U.S. federal income tax structure of the transactions contemplated hereby and all materials of any kind (including
opinions or other tax analyses) that are provided to it relating to such tax treatment and tax structure; provided that no disclosure of any information relating to such tax treatment or tax structure may be made to the extent nondisclosure
is reasonably necessary in order to comply with applicable securities laws. 
 10.16 WAIVERS OF JURY TRIAL. HOLDINGS, THE BORROWER,
THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN. 
 10.17 Patriot Act. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Loan Parties that
pursuant to the requirements of the Patriot Act, it may be required to obtain, verify and record information that identifies each Loan Party, which information includes the name and address of such Loan Party and other information that will allow
such Lender or the Administrative Agent, as applicable, to identify such Loan Party in accordance with the Patriot Act. The Borrower shall, and shall cause each Subsidiary to, provide, to the extent commercially reasonable, such information and take
such actions as are reasonably requested by the Administrative Agent or any Lenders in order to assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act. 
 SECTION 11. GUARANTY 
 11.1 Guaranty; Limitation of
Liability. 
 (a) Each Guarantor hereby absolutely, unconditionally and irrevocably guarantees the punctual payment when due, whether at
scheduled maturity or on any date of a required prepayment or by acceleration, demand or otherwise, of all Obligations of the Borrower and each other Guarantor now or hereafter existing under or in respect of this Agreement or any Loan Document
(including, without limitation, any extensions, modifications, substitutions, amendments or renewals of any or all of the foregoing Obligations), whether direct or indirect, absolute or contingent, and whether for principal, interest, premiums,
fees, indemnities, contract causes of action, costs, expenses or otherwise (such Obligations being the “Guarantied Obligations”), and agrees to pay any and all expenses incurred by the Administrative Agent or any Lender in enforcing
any rights under this Agreement or any Loan Document. Without 

  

 109 







 
limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guarantied Obligations and
would be owed by any other Loan Party to the Administrative Agent or any Lender under or in respect of this Agreement and the Loan Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving such other Loan Party. 
 (b) Each of the Guarantors, the Administrative Agent and the Lenders
hereby confirms that it is the intention of all such Persons that this Guaranty and the Obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of Debtor Relief Laws, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar law to the extent applicable to this Guaranty and the Obligations of each Guarantor hereunder. To effectuate the foregoing intention, the Administrative Agent, the Lenders and the Guarantors
hereby irrevocably agree that the Obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the Obligations of such Guarantor under this Guaranty not constituting a fraudulent transfer or
conveyance. 
 (c) Each Guarantor hereby unconditionally and irrevocably agrees that in the event any payment shall be required to be made to
the Administrative Agent or any Lender under this Guaranty, such Guarantor will contribute, to the maximum extent permitted by law, such amounts to each other Guarantor so as to maximize the aggregate amount paid in respect of this Agreement and the
Loan Documents. 
 11.2 Guaranty Absolute. Each Guarantor guarantees that the Guarantied Obligations will be paid strictly in
accordance with the terms of this Agreement and the Loan Documents, regardless of any law now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Administrative Agent or any Lender with respect thereto. The
Obligations of each Guarantor under or in respect of this Guaranty are independent of the Guarantied Obligations or any other Obligations of any other Loan Party under or in respect of this Agreement or the Loan Documents, and a separate action or
actions may be brought and prosecuted against each Guarantor to enforce this Agreement, irrespective of whether any action is brought against the Borrower or any other Loan Party or whether the Borrower or any other Loan Party is joined in any such
action or actions. This Guaranty is a present and continuing, absolute and unconditional guaranty of payment when due, and not of collection, by each Guarantor jointly and severally with any other Guarantor of the Guarantied Obligations. The
liability of each Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives, to the extent permitted by applicable law, any defenses it may now have or hereafter
acquire in any way relating to, any or all of the following: 
 (a) any lack of validity or enforceability of this Agreement or any Loan
Document or any agreement or instrument relating thereto; 
 (b) any change in the time, manner or place of payment of, or in any other term
of, all or any of the Guarantied Obligations or any other Obligations of any other Loan 

  

 110 







 
Party under or in respect of this Agreement or the Loan Documents, or any other amendment or waiver of or any consent to departure from this Agreement or any
Loan Document, including, without limitation, any increase in the Guarantied Obligations resulting from the extension of additional credit to any Loan Party or any of its Subsidiaries or otherwise; 
 (c) any taking, exchange, release, subordination or non-perfection of any Collateral, or any taking, release, subordination or amendment or waiver of, or
consent to departure from, any other guaranty, for all or any of the Guarantied Obligations;

otherwise, all as though such payment had not been made.

 (a) Each
Guarantor hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Borrower, any other Loan Party or any other guarantor that arise from the existence, payment, performance or
enforcement of such Guarantor’s Obligations under or in respect of this Agreement or any Loan Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution (pursuant to Section 11.1(c) or

right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Borrower, any other Loan Party or any other guarantor, directly or indirectly, in cash or other property or by
setoff or in any other manner, payment or security on account of such claim, remedy or right, unless and until the Guarantied Obligations have been paid in full and the Lenders have no further obligation to extend credit pursuant hereto. 

(b) Each Guarantor hereby agrees that any and all debts, liabilities and other obligations owed to such Guarantor by each other Loan Party, including
pursuant to Section 11.1(c) (collectively, the “Subordinated Obligations”), are hereby subordinated to the prior payment in full in cash of the Obligations of such other Loan Party hereunder and under the Loan Documents to the
extent and in the manner hereinafter set forth in this Section 11.4(b):

and the Lenders shall be entitled to receive payment in full in cash of all Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Debtor Relief Law, whether or not constituting an allowed claim in
such proceeding (“Post Petition Interest”)) before such Guarantor receives payment of any Subordinated Obligations. 
 (iii) After the occurrence and during the continuance of any Event of Default, each Guarantor shall, if the Administrative Agent so requests, collect, enforce and receive payments on account of the Subordinated Obligations 

  

 113 







 
as trustee for the Administrative Agent and the Lenders and deliver such payments to the Administrative Agent for application to the Guarantied Obligations
(including all Post Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of such Guarantor under the other provisions of this Agreement.

 (iv) After the occurrence and during the continuance of any Event of Default, the Administrative Agent is authorized and
empowered (but without any obligation to so do), in its discretion, (A) in the name of any Guarantor, to collect and enforce, and to submit claims in respect of, Subordinated Obligations and to apply any amounts received thereon to the
Guarantied Obligations (including any and all Post Petition Interest), and (B) to require any Guarantor (1) to collect and enforce, and to submit claims in respect of, Subordinated Obligations and (2) to pay any amounts received on
such obligations to the Administrative Agent for application to the Guarantied Obligations (including any and all Post Petition Interest). 
 (c) If any amount shall be paid to any Guarantor in violation of this Section 11.4, such amount shall be received and held in trust for the benefit of the Administrative Agent and the Lenders, shall be segregated from other property
and funds of such Guarantor and shall forthwith be paid or delivered to the Administrative Agent in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the Guarantied Obligations and all other
amounts payable under this Agreement or any of the Loan Documents, whether matured or unmatured, in accordance with the terms of this Agreement or any of the Loan Documents, or to be held as Collateral for any Guarantied Obligations or other amounts
payable under this Agreement or any of the Loan Documents thereafter arising. 
 11.5 Continuing Guaranty. This Guaranty is a
continuing agreement of each Guarantor and shall: (a) be binding upon such Guarantor, its successors and assigns and (b) inure to the benefit of and be enforceable by the Administrative Agent and the Lenders and their successors,

 Annex A 
 PRICING GRID FOR REVOLVING LOANS AND 
 SWINGLINE LOANS

	 	 Applicable Margin for
 Base Rate Loans

	 I
	 	2.000%	 	1.000%
	 II
	 	1.875%	 	0.875%
	 III
	 	1.750%	 	0.750%
	 IV

 The Applicable Margin for Revolving Loans and Swingline Loans shall be adjusted, on and after the first Adjustment
Date (as defined below) occurring after the completion of one full fiscal quarter of Holdings after the Closing Date and on each subsequent Adjustment Date, based on changes in the Consolidated Leverage Ratio, with such adjustments to become
effective on the date (the “Adjustment Date”) that is three Business Days after the date on which the relevant financial statements are delivered to the Lenders pursuant to Section 6.1 and to remain in effect until the next
adjustment to be effected pursuant to this paragraph. If any financial statements referred to above are not delivered within the time periods specified in Section 6.1, then, until the date that is three Business Days after the date on which
such financial statements are delivered, the highest rate set forth in each column of the Pricing Grid shall apply. On each Adjustment Date, the Applicable Margin for Revolving Loans and Swingline Loans shall be adjusted to be equal to the
Applicable Margin opposite the Pricing Level determined to exist on such Adjustment Date from the financial statements relating to such Adjustment Date. 
 As used herein, the following rules shall govern the determination of Pricing Levels on each Adjustment Date: 
 “Pricing Level I” shall exist on an Adjustment Date if the Consolidated Leverage Ratio for the relevant period is greater than or equal to 8.00 to 1.00. 
 “Pricing Level II” shall exist on an Adjustment Date if the Consolidated Leverage Ratio for the relevant period is less than 8.00 to
1.00 but greater than or equal to 7.50 to 1.00. 
 “Pricing Level III” shall exist on an Adjustment Date if the Consolidated
Leverage Ratio for the relevant period is less than 7.50 to 1.00 but greater than or equal to 7.00 to 1.00. 






 “Pricing Level IV” shall exist on an Adjustment Date if the Consolidated Leverage Ratio
for the relevant period is less than 7.00 to 1.00.
