(e)     Except as otherwise set forth herein, interest on each Revolving Loan and Incremental Term Loan (i) shall accrue on a daily basis and shall be payable in arrears on each Interest Payment Date with respect to interest accrued on and to each such payment date; (ii) shall accrue on a daily basis and shall be payable in arrears upon any prepayment of that Revolving Loan or Incremental Term Loan, as applicable , whether voluntary or mandatory, to the extent accrued on the amount being prepaid; and (iii) shall accrue on a daily basis and shall be payable in arrears at maturity of the Revolving Loans or Incremental Term Loans, as applicable , including final maturity of the Revolving Loans or Incremental Term Loans, as applicable .

For the purposes of the Interest Act (Canada) and disclosure under such act, whenever interest to be paid under this Agreement is to be calculated on the basis of a year of 360 or 365 days or any other period of time that is less than a calendar year, the yearly rate of interest to which the rate used pursuant to such calculation is equivalent is the rate so used multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by either 360 or 365 or such other period of time, as the case may be.

fifth , if an Event of Default shall have occurred and be continuing, to provide Cash Collateral for undrawn Letters of Credit; provided that such Cash Collateral shall be subsequently released and returned to Borrower (i) at such time as such Event of Default is no longer continuing and (ii) if such Event of Default is continuing, (x) in proportion to any reductions in the maximum exposure with respect to such Letters of Credit and (y) in full upon the termination and return of such Letters of Credit undrawn; provided that, (1) in the case of a release pursuant to clause (i) above, if any Obligations set forth in priority second are outstanding at the time of such release or (2) in the case of a release pursuant to clause (ii) above, if any Obligations set forth in priorities second through fourth are outstanding, then, such Cash Collateral shall first be applied to the repayment of such Obligations, as applicable, in accordance with this Section 2.13(b) .

(c)     Application of Prepayments of Revolving Loans to Base Rate Loans, Primate Rate Loans, Eurodollar Rate Loans and CDOR Loans . Considering each Type of Loan being prepaid separately, any prepayment thereof shall be applied first to Base Rate Loans or

Agent together with interest thereon, for each day from such Credit Date until the date such amount is paid to Administrative Agent, at the rate payable hereunder for Base Rate Loans or Canadian Prime Rate Loans for such Type of Loan. Nothing in this Section 2.14(b) shall be deemed to relieve any Lender from its obligation to fulfill its Revolving Commitments hereunder or to prejudice any rights that Borrowers may have against any Lender as a result of any default by such Lender hereunder. A notice of Administrative Agent to any Lender or Borrowers with respect to any amount owing under this subsection (b) shall be conclusive, absent manifest error.

(c)    Unless Administrative Agent shall have received notice from Borrowers prior to the date on which any payment is due to Administrative Agent for the account of the Lenders or the LC Issuing Banks hereunder that Borrowers will not make such payment, Administrative Agent may assume that Borrowers have made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the LC Issuing Banks, as the case may be, the amount due. In such event, if Borrowers have not in fact made such payment, then each of the Lenders or the LC Issuing Banks, as the case may be, severally agrees to repay to Administrative Agent forthwith on demand the amount so distributed to such Lender or the LC Issuing Banks, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to Administrative Agent, at the Overnight Rate.

(d)    All payments in respect of the principal amount of any Loan (other than voluntary prepayments of Loans that are Base Rate Loans or Canadian Prime Rate Loans as provided in Section 2.11(a)(ii)(2) shall be accompanied by payment of accrued interest on the principal amount being repaid or prepaid. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest, fees, costs and expenses then due hereunder, such funds shall be applied (i) first , towards payment of interest, fees costs and expenses then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second , towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(e)    Administrative Agent (or its agent or sub-agent appointed by it) shall promptly distribute to each Lender at such address as such Lender shall indicate in writing, such Lender’s applicable share of all payments and prepayments of principal and interest due hereunder, together with all other amounts due thereto, including all fees payable with respect thereto, to the extent received by Administrative Agent, pro rata in accordance with the amounts thereof then due and payable.

(f)    Notwithstanding the foregoing provisions hereof, if any Conversion/Continuation Notice is withdrawn as to any Affected Lender or if any Affected Lender makes Base Rate Loans or Canadian Prime Rate Loans in lieu of its Pro Rata Share of any Eurodollar Rate Loans or CDOR Loans (as applicable), Administrative Agent shall give effect thereto in apportioning payments received thereafter.

(g)    Subject to the provisos set forth in the definition of “Interest Period” as they may apply to Revolving Loans or Incremental Term Loans , whenever any payment to be made hereunder with respect to any Revolving Loan or Incremental Term Loan shall be stated to

Due to such other Lender, then the Lender receiving such proportionately greater payment shall (a) notify Administrative Agent and each other Lender of the receipt of such payment and (b) apply a portion of such payment to purchase participations (which it shall be deemed to have purchased from each seller of a participation simultaneously upon the receipt by such seller of its portion of such payment) in the Aggregate Amounts Due to the other Lenders so that all such recoveries of Aggregate Amounts Due shall be shared by all Lenders in proportion to the Aggregate Amounts Due to them; provided , if all or part of such proportionately greater payment received by such purchasing Lender is thereafter recovered from such Lender upon the bankruptcy or reorganization of Borrowers or otherwise, those purchases shall be rescinded and the purchase prices paid for such participations shall be returned to such purchasing Lender ratably to the extent of such recovery, but without interest. Borrowers expressly consent to the foregoing arrangement and agree that any holder of a participation so purchased may exercise any and all rights of banker’s lien, set-off or counterclaim with respect to any and all monies owing by Borrowers to that holder with respect thereto as fully as if that holder were owed the amount of the participation held by that holder. The provisions of this Section 2.15 shall not be construed to apply to (a) any payment made by Borrowers pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (b) any payment obtained by any Lender as consideration for the assignment or sale of a participation in any of its Loans or other Obligations owed to it or (c) any payment to an LC Issuing Bank or the Swingline Lenders of a reimbursement obligation in accordance with Section 2.3(c)(i) or Section 2.1(c) , as applicable.

(1)      in the event that Administrative Agent (upon the written instruction of the Required Lenders) shall have determined in good faith (which determination shall be final and conclusive and binding upon all parties hereto), on any Interest Rate Determination Date with respect to any Eurodollar Rate Loans or CDOR Loans, that (1) by reason of circumstances affecting the applicable interbank market adequate and fair means do not exist for ascertaining the interest rate applicable to such Loans on the basis provided for in the definition of Eurodollar Rate or CDOR Rate or (2) deposits are not being offered to banks in the applicable offshore interbank market for such currency for the applicable amount and Interest Period of such Eurodollar Rate Loan or CDOR Loan, Administrative Agent shall on such date give notice (by facsimile or by telephone confirmed in writing) to Borrowers and each Lender of such determination, whereupon (i) (x) no Loans may be made as, or converted to, Eurodollar Rate Loans or CDOR Loans and (ii) (y) in the event of a determination with respect to the Eurodollar Rate component of the Base Rate or the CDOR Rate component of the Canadian Prime Rate, the utilization of the Eurodollar Rate or CDOR Rate component in determining the Base Rate or Canadian Prime Rate shall be

suspended, in each case until Administrative Agent (upon the written instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, Borrowers may revoke any pending Borrowing Notice And Certificate or Conversion/Continuation Notice of Eurodollar Rate Loans or CDOR Loans in the affected currency or currencies or, failing that, will be deemed to have converted such request into a request for a borrowing of Base Rate Loans or Canadian Prime Rate Loans in the amount specified therein . ; and

(2)      if at any time the Required Revolving Lenders determine (which determination shall be conclusive absent manifest error) that the Eurodollar Rate shall cease to exist, then the Required Revolving Lenders and the Borrower shall endeavor to establish an alternate rate of interest to the Eurodollar Rate that gives due consideration to the then prevailing market convention for determining a rate of interest for syndicated loans in the United States at such time, and shall enter into an amendment to this Agreement to reflect such alternate rate of interest and such other related changes to this Agreement as may be applicable.

(ii)      With respect to any 2019 Incremental Term Loans:

(1)      if prior to the commencement of any Interest Period for a Eurodollar Rate Loan:

a.      by reason of circumstances affecting the applicable interbank market adequate and fair means do not exist for ascertaining the interest rate applicable to such Loans on the basis provided for in the definition of Eurodollar Rate; or

b.      deposits are not being offered to banks in the applicable offshore interbank market for such currency for the applicable amount and Interest Period of such Eurodollar Rate Loan,

then the Administrative Agent shall give notice thereof to the Borrowers and the 2019 Incremental Term Loan Lenders by telephone, telecopy or electronic mail as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrowers and the 2019 Incremental Term Loan Lenders that the circumstances giving rise to such notice no longer exist, any Conversion/Continuation Notice that requests the conversion of any Loan to, or continuation of any Loan as, a Eurodollar Rate Loan shall be ineffective, and, such Borrowing (unless prepaid) shall be continued as, or converted to, a Base Rate Loan; provided that (x) if the circumstances giving rise to such notice do not affect all the 2019 Incremental Term Loan Lenders, then requests by the Borrowers for Eurodollar Rate Loans may be made to 2019 Incremental Term Loan Lenders that are not affected thereby and (y) if the

circumstances giving rise to such notice affect only one Type of Loan, then the other Type of Loan shall be permitted.

(2)      if the Administrative Agent (i) determines that the circumstances described in clauses (a)(ii)(1)(a) or (a)(ii)(1)(b) of this Section 2.16 have arisen and such circumstances are unlikely to be temporary, (ii) determines that the circumstances described in clauses (a)(ii)(1)(a) or (a)(ii)(1)(b) of this Section 2.16 have not arisen but the supervisor for the administrator of the Eurodollar Rate or a Governmental Authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which the Eurodollar Rate shall no longer be used for determining interest rates for loans or (iii) new syndicated loans have started to adopt a new benchmark interest rate, then the Administrative Agent and the Borrowers shall endeavor to establish an alternate rate of interest to the Eurodollar Rate that gives due consideration to the then prevailing market convention for determining a rate of interest for syndicated loans in the United States at such time, and shall enter into an amendment to this Agreement to reflect such alternate rate of interest and such other related changes (including administrative changes) to this Agreement as may be applicable; provided that to the extent that the Administrative Agent determines that adoption of any portion of such market convention is not administratively feasible or that no market convention for the administration of such alternate rate of interest exists, the Administrative Agent shall administer such alternate rate of interest in a manner determined by the Administrative Agent in consultation with the Borrowers. Notwithstanding anything to the contrary in Section 10.5, such amendment shall become effective without any further action or consent of any other 2019 Incremental Term Loan Lender so long as the Administrative Agent shall not have received, within five (5) Business Days of the date notice of such alternate rate of interest is provided to the 2019 Incremental Term Loan Lenders, a written notice from the Required 2019 Incremental Term Loan Lenders stating that such Required 2019 Incremental Term Loan Lenders object to such amendment. If a notice of an alternate rate of interest has been given and no such alternate rate of interest has been determined, and (x) the circumstances under clause (i) or (iii) above exist or (y) the specific date referred to in clause (ii) has occurred (as applicable), the Base Rate shall apply without regard to clause (iii) of the definition thereof; provided that, if such alternate rate of interest shall be less than zero, such rate shall be deemed to be zero for the purposes of this Agreement.

(b)     Illegality or Impracticability of Eurodollar Rate Loans or CDOR Loans . In the event that on any date any Lender shall have determined in good faith (which determination shall be final and conclusive and binding upon all parties hereto but shall be made only after consultation with Borrowers and Administrative Agent) that the making, maintaining or

continuation of its Eurodollar Rate Loans or CDOR Loans (i) has become unlawful as a result of compliance by such Lender in good faith with any Governmental Rule (or would conflict with

borrowing, or a conversion to or continuation of any Eurodollar Rate Loan or CDOR Loan does not occur on a date specified therefor in a Conversion/Continuation Notice or a telephonic request for conversion or continuation; (ii) if any prepayment or other principal payment under Sections 2.11 or 2.12 of, or any conversion of, any of its Eurodollar Rate Loans or CDOR Loans occurs on a date prior to the last day of an Interest Period applicable to that Loan; (iii) if any prepayment of any of its Eurodollar Rate Loans or CDOR Loans is not made on any date specified in a notice of prepayment given by Borrowers; and (iv) if an assignment of any Loan by a Terminated Lender pursuant to Section 2.16(c) occurs on a date prior to the last day of an Interest Period applicable to that Loan.

(d)     Assumptions Concerning Funding of Eurodollar Rate Loans or CDOR Loans . Calculation of all amounts payable to a Lender under Section 2.16(c) shall be made as though such Lender had actually funded each of its relevant Eurodollar Rate Loans or CDOR Loans through the purchase of a Eurodollar deposit bearing interest at the rate obtained pursuant to clause (i) of the definition of Eurodollar Rate or CDOR Rate in an amount equal to the amount of such Eurodollar Rate Loan or CDOR Loan and having a maturity comparable to the relevant Interest Period and through the transfer of such Eurodollar deposit or CDOR deposit from an offshore office of such Lender to a domestic office of such Lender in the United States of America; provided , however , each Lender may fund each of its Eurodollar Rate Loans or CDOR Loans in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under Section 2.16(c) .

2.17    Increased Costs; Capital or Liquidity Adequacy

(a)     Compensation For Increased Costs and Taxes . Subject to the provisions of Section 2.18 (which shall be controlling with respect to the matters covered thereby), in the event that any Lender (which term shall include each LC Issuing Bank for purposes of this Section 2.17(a) ) shall determine that any Change in Law: (i) subjects such Lender (or its applicable lending office) to any additional Tax (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) with respect to this Agreement or any of the other Credit Documents or any of its obligations hereunder or thereunder or any payments to such Lender (or its applicable lending office) of principal, interest, fees or any other amount payable hereunder; (ii) imposes, modifies or holds applicable any reserve (including any marginal, emergency, supplemental, special or other reserve), special deposit, compulsory loan, FDIC insurance or similar requirement against assets held by, or deposits or other liabilities in or for the account of, or advances or loans by, or other credit extended by, or any other acquisition of funds by, any office of such Lender, or (iii) imposes any other condition, cost or expense (other than with respect to Taxes) on or affecting such Lender (or its applicable lending office) or its obligations hereunder or the applicable interbank market; and the result of any of the foregoing is to increase the cost to such Lender of agreeing to make, making, continuing, converting into or maintaining Revolving Loans hereunder or to reduce any amount received or receivable by such Lender (or its applicable lending office) with respect thereto; then each Borrower shall promptly pay to such Lender, upon receipt of the statement referred to in the next sentence, such additional amount or amounts (in the form of an increased rate of, or a different method of calculating, interest

or otherwise as such Lender in its sole discretion shall determine) as may be necessary to compensate such Lender for any such increased cost or reduction in amounts received or

10.18    Usury Savings Clause.

(a)    Notwithstanding any other provision herein, the aggregate interest rate charged with respect to any of the Obligations, including all charges or fees in connection therewith deemed in the nature of interest under applicable Governmental Rules shall not exceed the Highest Lawful Rate. If the rate of interest (determined without regard to the preceding sentence) under this Agreement at any time exceeds the Highest Lawful Rate, the outstanding amount of the Revolving Loans made hereunder shall bear interest at the Highest Lawful Rate until, to the extent permitted by Governmental Rules, the total amount of interest due hereunder equals the amount of interest which would have been due hereunder if the stated rates of interest set forth in this Agreement had at all times been in effect. In addition, if when the Revolving Loans made hereunder are repaid in full the total interest due hereunder (taking into account the increase provided for above) is less than the total amount of interest which would have been due hereunder if the stated rates of interest set forth in this Agreement had at all times been in effect, then to the extent permitted by

Governmental Rules, Borrowers shall pay to Administrative Agent an amount equal to the difference between the amount of interest paid and the amount of interest which would have been paid if the Highest Lawful Rate had at all times been in effect. Notwithstanding the foregoing, it is the intention of Lenders and Borrowers to conform strictly to any applicable usury laws. Accordingly, if any Lender contracts for, charges, or receives any consideration which constitutes interest in excess of the Highest Lawful Rate, then any such excess shall be deemed to be adjusted to the Highest Lawful Rate as if such excess had never existed, cancelled automatically and, if previously paid, shall at such Lender’s option be applied to the outstanding amount of the Revolving Loans made hereunder or be refunded to Borrowers.

(b)     Canadian Usury . If any provision of this Agreement would obligate the Canada Borrower to make any payment of interest or other amount payable to any Lender domiciled in Canada in an amount or calculated at a rate which would be prohibited by law or would result in a receipt by that Lender of “interest” at a “criminal rate” (as such terms are construed under the Criminal Code (Canada)), then, notwithstanding such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by law or so result in a receipt by such Lender domiciled in Canada of “interest” at a “criminal rate”, such adjustment to be effected, to the extent necessary (but only to the extent necessary), as follows: (i) first, by reducing the amount or rate of interest or the amount or rate of any Letter of Credit Fee required to be paid to the affected Lender under Section 2.10(b)(ii) , and (ii) thereafter, by reducing any fees, commissions, premiums and other amounts required to be paid to the affected Lender which would constitute interest for purposes of Section 347 of the Criminal Code (Canada).
