 [Reverse of Security] 
 FEDERAL REALTY INVESTMENT TRUST 
 6.20% Note due 2017 
 This Note is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or
more series under an Indenture, dated as of September 1, 1998 (herein called the “Indenture”), between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee”, which term includes any successor
trustee under the Indenture with respect to the series of which this Note is a part), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Note is one of the duly authorized series of Securities designated
as “6.20% Notes due 2017” (collectively, the “Notes”), and the aggregate principal amount of the Notes to be issued under such series is initially limited to $130,000,000 (except for Notes authenticated and delivered upon
transfer of, or in exchange for, or in lieu of other Notes). The Company may, without the consent of the Holders of any Securities, create and issue additional notes in the future having the same terms other than the date of original issuance, the
issue price and the date on which interest begins to accrue so as to form a single series with the Notes. The Notes are the unsecured and unsubordinated obligations of the Company and rank equally with all existing and future unsecured and
unsubordinated indebtedness of the Company. All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 
 If an Event of Default, as defined in the Indenture, shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the
Indenture. 
 The Notes are subject to redemption at any time, in whole or in part, at the election of the Company, at a redemption price
equal to the greater of (1) 100% of the principal amount of the Notes being redeemed, or (2) as determined by the Quotation Agent (as defined below), the sum of the present values of the remaining scheduled payments of principal and
interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate (as defined below) plus 20 basis points plus, in each case, accrued interest thereon to the Redemption Date; provided, however, that installments of interest on this Note whose Stated Maturity Date is on or prior to such Redemption
Date will be payable to the Holder of this Note, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. 
 As used herein: 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable 
  

 4 

 Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for such Redemption Date. 
 “Comparable Treasury
Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and
lowest such Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than three such Reference Treasury Dealer quotations, the average of all such Quotations. 
 “Quotation Agent” means the Reference Treasury Dealer appointed by the Company. 
 “Reference Treasury Dealer” means (1) Citigroup Global Markets Inc. and other primary U.S. Government securities
dealers in New York City selected by Wachovia Capital Markets, LLC, and their respective successors; provided, however, that if Citigroup Global Markets Inc. ceases to be a primary U.S. Government securities dealer (a “Primary Treasury
Dealer”), the Company will substitute therefor another Primary Treasury Dealer; and (2) any other Primary Treasury Dealer selected by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the
average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third Business Day preceding such Redemption Date. 
 Notice of any redemption will be given by mail to Holders of
Securities, not less than 30 nor more than 60 days prior to the Redemption Date, all as provided in the Indenture. 
 In the event of
redemption of this Note in part only, a new Note or Notes for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the
Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of all Securities issued under the Indenture at the time Outstanding and affected thereby. The
Indenture also contains provisions permitting the Holders of not less than a majority of the aggregate principal amount of the Outstanding Securities, on behalf of the Holders of all such 
  

 5 

 Securities, to waive compliance by the Company with certain provisions of the Indenture. Furthermore, provisions in the
Indenture permit the Holders of not less than a majority of the aggregate principal amount, in certain instances, of the Outstanding Securities of any series to waive, on behalf of all of the Holders of Securities of such series, certain past
defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and other Notes issued upon the registration of
transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
 No
reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at
the times, places and rate, and in the coin or currency, herein prescribed. 
 The Company will not, and will not permit any Subsidiary to,
incur any Debt (as defined below) if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds thereof, the aggregate principal amount of all outstanding Debt of the Company and its Subsidiaries on a
consolidated basis determined in accordance with generally accepted accounting principles is greater than 60% of the sum of (without duplication) (i) Total Assets as of the end of the calendar quarter covered in the Company’s Annual Report
on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Securities and Exchange Commission (or, if such filing is not permitted under the Securities Exchange Act of 1934, with the Trustee) prior to the
incurrence of such additional Debt and (ii) the purchase price of any real estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire real
estate assets or mortgages receivable or used to reduce Debt), by the Company or any Subsidiary since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Debt. 
 In addition to the foregoing limitation on the incurrence of Debt, the Company will not, and will not permit any Subsidiary to, incur any Debt secured by
any mortgage, lien, charge, pledge, encumbrance or security interest of any kind upon any of the property of the Company or any Subsidiary if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds
thereof, the aggregate principal amount of all outstanding Debt of the Company and its Subsidiaries on a consolidated basis which is secured by any mortgage, lien, charge, pledge, encumbrance or security interest on property of the Company or any
Subsidiary is greater than 40% of the sum of (without duplication) (1) Total Assets as of the end of the calendar quarter covered in the Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most
recently filed with the Securities and Exchange Commission (or, if such filing is not permitted under the Securities Exchange Act of 1934, with the Trustee) prior to the incurrence of such additional Debt and (2) the purchase price of any real
estate assets or mortgages receivable acquired, and the amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire real estate assets or mortgages receivable or used to reduce Debt), by the Company or
any Subsidiary since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Debt; provided, however, that for purposes of this limitation, the amount of obligations under capital
leases shown as a liability on the Company’s consolidated balance sheet shall be deducted from Debt and Total Assets. 
  

 6 

 Furthermore, the Company will not, and will not permit any Subsidiary to, incur any Debt if the ratio of
Consolidated Income Available for Debt Service (as defined below) to the Annual Debt Service Charge (as defined below) for the four consecutive fiscal quarters most recently ended prior to the date on which such additional Debt is to be incurred
shall have been less than 1.5 to 1, on an unaudited pro forma basis after giving effect thereto and to the application of the proceeds therefrom, and calculated on the assumption that (i) such Debt and any other Debt incurred by the Company and
its Subsidiaries since the first day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Debt, had occurred at the beginning of such period; (ii) the repayment or retirement of any other Debt
by the Company and its Subsidiaries since the first day of such four-quarter period had been repaid or retired at the beginning of such period (except that, in making such computation, the amount of Debt under any revolving credit facility shall be
computed based upon the average daily balance of such Debt during such period); (iii) in the case of Acquired Debt or Debt incurred in connection with any acquisition since the first day of such four-quarter period, the related acquisition had
occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition being included in such unaudited pro forma calculation; and (iv) in the case of any acquisition or disposition by the Company or its
Subsidiaries of any asset or group of assets since the first day of such four-quarter period, whether by merger, stock purchase or sale, or asset purchase or sale, such acquisition or disposition or any related repayment of Debt had occurred as of
the first day of such period with the appropriate adjustments with respect to such acquisition or disposition being included in such unaudited pro forma calculation. 
 Furthermore, the Company and its Subsidiaries taken as a whole, will, at all times maintain an Unencumbered Total Asset Value (as defined below) in an amount not less than 150% of the aggregate outstanding principal
amount of the unsecured Debt of the Company and its Subsidiaries, taken as a whole. 
 As used herein, 
 “Acquired Debt” means Debt of a Person (i) existing at the time such Person becomes a Subsidiary or (ii) assumed in
connection with the acquisition of assets from such Person, in each case, other than Debt incurred in connection with, or in contemplation of, such Person becoming a Subsidiary or such acquisition. Acquired Debt shall be deemed to be incurred on the
date of the related acquisition of assets from any Person or the date the acquired Person becomes a Subsidiary. 
 “Annual Debt Service Charge” as of any date means the maximum amount which is payable in any period for interest on, and original issue discount of, Debt of the Company and its Subsidiaries and the amount of dividends which are
payable in respect of any Disqualified Stock (as defined below).

any thereof. 
 “Consolidated Income Available for Debt Service” for any period means Funds from Operations (as
defined below) of the Company and its Subsidiaries plus amounts which have been deducted for interest on Debt of the Company and its Subsidiaries.

instruments, (ii) indebtedness secured by any mortgage, pledge, lien, charge, encumbrance or any security interest existing on property owned by the Company or any Subsidiary, (iii) the reimbursement obligations, contingent or otherwise,

conditional sale obligations or obligations under any title retention agreement, (iv) the principal amount of all obligations of the Company or any Subsidiary with respect to redemption, repayment or other repurchase of any Disqualified Stock
or (v) any lease of property by the Company or any Subsidiary as lessee which is reflected on the Company’s consolidated balance sheet as a capitalized lease in accordance with generally accepted accounting principles to the extent, in the
case of items of indebtedness under (i) through (iii) above, that any such items (other than letters of credit) would appear as a liability on the Company’s consolidated balance sheet in accordance with generally accepted accounting
principles, and also includes, to the extent not otherwise included, any obligation of the Company or any Subsidiary to be liable for, or to pay, as obligor, guarantor or otherwise (other than for purposes of collection in the ordinary course of
business or for the purposes of guaranteeing the payment of all amounts due and owing pursuant to leases to which the Company is a party and has assigned its interest, provided that such assignee of the Company is not in default of any amounts due
and owing under such leases), Debt of another Person (other than the Company or any Subsidiary) (it being understood that Debt shall be deemed to be incurred by the Company or any Subsidiary whenever the Company or such Subsidiary shall create,
assume, guarantee or otherwise become liable in respect thereof).

determined in accordance with generally accepted accounting principles (but excluding goodwill).

be issued if 
  

 30 

 after giving effect thereto the sum of (A) the aggregate outstanding principal amount of Canadian
Revolving Loans plus (B) the aggregate Letter of Credit Liabilities relating to Canadian Letters of Credit plus (C) the aggregate Bankers’ Acceptance Liabilities would exceed the Maximum Canadian Available Amount. No U.K. Letter of
Credit may be issued if after giving effect thereto the sum of (A) the aggregate outstanding principal amount of U.K. Revolving Loans plus (B) the aggregate Letter of Credit Liabilities relating to U.K. Letters of Credit would exceed the
Maximum U.K. Available Amount. On each day during the period commencing with the issuance of any Letter of Credit and until such Letter of Credit shall have expired or been terminated, the U. S. Commitment, Canadian Commitment or U.K. Commitment, as
the case may be, of each applicable Lender shall be deemed to be utilized for all purposes hereof, including Section 2.5(a), in an amount equal to such Lender’s Commitment Percentage of the amount then available for drawings under
such Letter of Credit (or any unreimbursed drawings under such Letter of Credit). 
 (iii) Upon receipt from the beneficiary
of any Letter of Credit of any demand for payment thereunder, the applicable Issuer shall notify the Agents and thereafter the U.S. Agent, the Canadian Agent or the U.K. Agent, as the case may be, shall promptly notify the applicable Borrower and
each applicable Lender as to the amount to be paid as a result of such demand and the payment date therefor. If at any time prior to the earlier of the expiration date of a Letter of Credit or the Termination Date any applicable Issuer shall have
made a payment to a beneficiary of a Letter of Credit in respect of a drawing under such Letter of Credit, each applicable Lender will pay to the U.S. Agent, the Canadian Agent or the U.K. Agent, as the case may be, immediately upon demand by such
Issuer at any time during the period commencing after such payment until reimbursement thereof in full by the applicable Borrower, an amount equal to such Lender’s Commitment Percentage of such payment, together with interest on such amount for
each day from the date of demand for such payment (or, if such demand is made after 11:00 a.m. Houston, Texas time (in the case of a U.S. Letter of Credit) or 12:00 noon Toronto, Ontario time (in the case of a Canadian Letter of Credit) or 11:00
a.m. London, United Kingdom time (in the case of a U.K. Letter of Credit) on such date, from the next succeeding Business Day) to the date of payment by such Lender of such amount at a rate of interest per annum equal to the Federal Funds Rate. To
the extent that it is ultimately determined that the applicable Borrower is relieved of its obligation to reimburse the applicable Issuer because of such Issuer’s gross negligence or willful misconduct in determining that documents received
under any applicable Letter of Credit comply with the terms thereof, the applicable Issuer shall be obligated to refund to the paying Lenders all amounts paid to such Issuer to reimburse Issuer for the applicable drawing under such Letter of Credit,
together with interest from the date of payment by such Lender to the date of repayment by the Issuing Bank at the interest rates set forth above applicable to such Lenders. 
 (iv) U.S. Borrower, the Canadian Borrower or U.K. Borrower, as the case may be, shall be irrevocably and unconditionally obligated
forthwith to reimburse the appropriate Agent, on the date on which such Agent notifies U.S. Borrower, the Canadian Borrower or U.K. Borrower, as the case may be, of the date and amount of any payment by the applicable Issuer of any drawing or
payment made under a Letter of Credit, for the 
  

 31 

 amount paid by such Issuer upon such drawing or payment, without presentment, demand, protest or other
formalities of any kind, all of which are hereby waived. Such reimbursement may, subject to satisfaction of the conditions in Sections 5.1 and 5.2 hereof, the limitations on size contained in Section 2.1 and to the Maximum
U.S. Available Amount, Maximum Canadian Available Amount or Maximum U.K. Available Amount, as the case may be (after adjustment in the same to reflect the elimination of the corresponding Letter of Credit Liability), be made by the borrowing of
Loans or, in the case of the Canadian Borrower, by the issuance, acceptance and purchase of Bankers’ Acceptances. The applicable Agent will pay to each Lender such Lender’s Commitment Percentage of all amounts received from U.S. Borrower,
the Canadian Borrower or the U.K. Borrower, as the case may be, for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Letter of Credit, but only to the extent such Lender has made payment to the
applicable Agent in respect of such Letter of Credit pursuant to clause (iii) above. To the extent such applicable Agent does not pay such Lender within the timeframes which are applicable to such Lenders in clause
(iii) above, such applicable Agent shall pay interest to such Lenders at the interest rates set forth in clause (iii) above applicable to such Lenders for such period of delay. 
 (v) U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, will pay to the appropriate Agent at the Principal
Office of such Agent for the account of each applicable Lender a letter of credit fee with respect to each Letter of Credit equal to the greater of (x) $750 or (y) the Margin Percentage then in effect with respect to LIBOR Borrowings
multiplied by the daily average amount available for drawings under each Letter of Credit (and computed on the basis of the actual number of days elapsed in a year composed of 360 days), in each case for the period from and including the date of
issuance of such Letter of Credit to and including the date of expiration or termination thereof, such fee to be due and payable quarterly in arrears on each three (3) month anniversary of the issuance of the applicable Letter of Credit and
upon expiration or termination of the applicable Letter of Credit. The applicable Agent will pay to each applicable Lender, promptly after receiving any payment in respect of letter of credit fees referred to in this clause (v), an amount
equal to the product of such Lender’s Commitment Percentage times the amount of such fees. In addition to and cumulative of the above described fees, U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, shall
pay to the appropriate Agent, for the account of the applicable Issuer, in advance on the date of the issuance of the applicable Letter of Credit, a fronting fee in an amount equal to the greater of (x) $500 or (y) 1/8% of the face amount
of the applicable Letter of Credit (such fronting fee to be retained by the applicable Issuer for its own account). 
 (vi)
The issuance by the applicable Issuer of each Letter of Credit shall, in addition to the conditions precedent set forth in Section 5 hereof, be subject to the conditions precedent (A) that such Letter of Credit shall be in such form
and contain such terms as shall be reasonably satisfactory to applicable Agent, and (B) that U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, shall have executed and delivered such Applications and other
instruments and agreements relating to such Letter of Credit as the applicable Agent shall have reasonably requested and are not inconsistent with the terms of this Agreement. In the event of a conflict between the terms of this Agreement and the
terms of any Application, the terms hereof shall control. 
  

 32 

 (vii) Each Issuer will send to U.S. Borrower, the Canadian Borrower or the U.K. Borrower,
as the case may be, and each applicable Lender, immediately upon issuance of any Letter of Credit issued by such Issuer or any amendment thereto, a true and correct copy of such Letter of Credit or amendment. 
 (c) Indemnification; Release. U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, hereby indemnifies and holds harmless
each Agent, each Lender and each Issuer from and against any and all claims, damages, losses, liabilities, costs or expenses which such Agent, such Lender or such Issuer may incur (or which may be claimed against such Agent, such Lender or such
Issuer by any Person whatsoever), REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY OF THE INDEMNIFIED PARTIES, in connection with the execution and delivery of any Letter of Credit or transfer of or payment or failure
to pay under any Letter of Credit; provided that U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, shall not be required to indemnify or hold harmless any party seeking indemnification for any claims, damages,
losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the party seeking indemnification or exoneration, or (ii) the failure by the party seeking
indemnification to pay under any Letter of Credit after the presentation to it of a request required to be paid under applicable law. U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, hereby releases, waives and
discharges each Agent, each Lender and each Issuer from any claims, causes of action, damages, losses, liabilities, reasonable costs or expenses which may now exist or may hereafter arise, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE
NEGLIGENCE OF ANY OF THE INDEMNIFIED PARTIES, by reason of or in connection with the failure of any Agent, any Issuer or any other Lender to fulfill or comply with its obligations to such Agent, such Lender or such Issuer, as the case may be,
hereunder (but nothing herein contained shall affect any rights U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, may have against such defaulting party or may have in respect of gross negligence or willful misconduct).
Nothing in this Section 2.2(c) is intended to limit the obligations of U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, under any other provision of this Agreement. 
 (d) Additional Costs in Respect of Letters of Credit. Subject to Sections 11.7 and 11.17 hereof, if as a result of any Regulatory
Change there shall be imposed, modified or deemed applicable any tax (other than any tax based on or measured by net income), reserve, special deposit or similar requirement against or with respect to or measured by reference to Letters of Credit
issued or to be issued hereunder or participations in such Letters of Credit, and the result shall be to increase the cost to any Lender of issuing or maintaining any Letter of Credit or any participation therein, or materially reduce any amount
receivable by any Lender hereunder in respect of any Letter of Credit or any participation therein (which increase in cost, or reduction in amount receivable, shall be the result of such Lender’s reasonable allocation of the aggregate of such
increases or reductions resulting from such event), then such Lender shall notify U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, through the appropriate Agent (which notice shall be accompanied by a statement setting
forth in reasonable 
  

 33 

 detail the basis for the determination of the amount due), and within 15 Business Days after demand therefor by such
Lender through such Agent, U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, shall pay to such Lender, from time to time as specified by such Lender, such additional amounts as shall be sufficient to compensate such
Lender for such increased costs or reductions in amount. Such statement as to such increased costs or reductions in amount incurred by such Lender, submitted by such Lender to U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case
may be, shall be conclusive as to the amount thereof, absent manifest error, and may be computed using any reasonable averaging and attribution method. Each Lender will notify U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case
may be, through the appropriate Agent of any event occurring after the date of this Agreement which will entitle such Lender to compensation pursuant to this Section 2.2(d) as promptly as practicable after any executive officer of such
Lender obtains knowledge thereof and determines to request such compensation, and (if so requested by U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, through the appropriate Agent) will designate a different lending
office of such Lender for the issuance or maintenance of Letters of Credit by such Lender or will take such other action as U.S. Borrower, the Canadian Borrower or the U.K. Borrower, as the case may be, may reasonably request if such designation or
action is consistent with the internal policy of such Lender and legal and regulatory restrictions, can be undertaken at no additional cost, will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of
such Lender, be disadvantageous to such Lender (provided that no such U.S. Lender shall have any obligation so to designate a different lending office which is not located in the United States of America, no such Canadian Lender shall have
any obligation so to designate a different lending office which is not located in Canada and no such U.K. Lender shall have any obligation so to designate a different lending office which is not located in the United Kingdom). 
 2.3 Certain Provisions Relating to Bankers’ Acceptances. 
 (a) Subject to the terms and conditions hereof, each Canadian Lender severally agrees to accept and purchase Bankers’ Acceptances drawn upon it by the Canadian Borrower denominated in Canadian Dollars. The
Canadian Borrower shall notify the Canadian Agent by irrevocable written notice (each a “Bankers’ Acceptance Notice”) by 12:00 noon (Toronto, Ontario time) two (2) Business Days prior to the proposed date of any borrowing
by way of Bankers’ Acceptances. Each borrowing by way of Bankers’ Acceptances shall be in a minimum aggregate face amount of C$1,000,000.00 and integral multiples of C$100,000.00 in excess thereof. The face amount of each Bankers’
Acceptance shall be C$100,000.00 or any integral multiple thereof. Each Bankers’ Acceptance Notice shall be in the form of Exhibit G. 
 (1) Bankers’ Acceptances shall be issued and shall mature on a Business Day. Each Bankers’ Acceptance shall have a term of approximately 1, 2 or 3 months or, if available, 6 months excluding days of grace
and shall mature on a Business Day on or before the Revolving Loan Maturity Date and shall be in form and substance reasonably satisfactory to each Canadian Lender. 
 (2) Subject to Section 2.3(a)(3), Bankers’ Acceptances shall be signed by duly authorized officers of the Canadian
Borrower or, in the alternative, the signatures of such officers may be mechanically reproduced in facsimile thereon and Bankers’ Acceptances 
  

 34 

 bearing such facsimile signatures shall be binding on the Canadian Borrower as if they had been manually
executed and delivered by such officers on behalf of the Canadian Borrower; notwithstanding that any person whose manual or facsimile signature appears on any Bankers’ Acceptance may no longer be an authorized signatory for the Canadian
Borrower on the date of issuance of a Bankers’ Acceptance, such signature shall nevertheless be valid and sufficient for all purposes as if such authority had remained in force at the time of such issuance and any such Bankers’ Acceptance
shall be binding on the Canadian Borrower; 
 (3) In lieu of the Canadian Borrower signing Bankers’ Acceptances in
accordance with Section 2.3(a)(2) and, for so long as the power of attorney in Section 2.3(a)(5) is in force with respect to a given Canadian Lender, such Canadian Lender shall execute and deliver Bankers’ Acceptances on
behalf of the Canadian Borrower in accordance with the provisions thereof and, for certainty, all references herein to drafts drawn by the Canadian Borrower, Bankers’ Acceptances executed by the Canadian Borrower or similar expressions shall be
deemed to include Bankers’ Acceptances executed in accordance with a power of attorney, unless the context otherwise requires; 
 (4) If and for so long as the power of attorney referred to in Section 2.3(a)(5) is in force with respect to each of the Canadian Lenders, it is intended that pursuant to the DBNA, all Bankers’ Acceptances accepted by the
Canadian Lenders under this Agreement will be issued in the form of a “depository bill” (as defined in the DBNA), deposited with a “clearing house” (as defined in the DBNA including The Canadian Depository for Securities Ltd. or
its nominee CDS & Co.). In order to give effect to the foregoing, the Canadian Agent will, subject to the approval of the Canadian Borrower and the Canadian Lenders, establish and notify the Canadian Borrower and the Canadian Lenders of any
additional procedures, consistent with the terms of this Agreement and the DBNA, as are reasonably necessary to accomplish such intention, including: 
  

	 	(i)	any instrument held by the Canadian Lenders for the purposes of Bankers’ Acceptances will have marked prominently and legibly on its face and within its text, at or before the
time of issue, the words “This is a depository bill subject to the Depository Bills and Notes Act (Canada)”; 

  

	 	(ii)	any reference to the authentication of the Bankers’ Acceptance will be removed; and 

  

	 	(iii)	any reference to the “bearer” will be removed and such Bankers’ Acceptances will not be marked with any words prohibiting negotiation, transfer or assignment of it or
of an interest in it. 

 (5) To facilitate the issuance and acceptance of Bankers’ Acceptances under this
Agreement, the Canadian Borrower hereby appoints each Canadian Lender, acting by any authorized signatory of such Lender, as its attorney: 
  

	 	(i)	to sign for and on behalf and in the name of the Canadian Borrower as drawer, drafts in such Canadian Lender’s standard form which are 

  

 35 

 depository bills as defined in the DBNA, payable to a “clearing house” (as defined in the
DBNA) including, without limitation, The Canadian Depository For Securities Limited or its nominee, CDS & Co. (the “clearing house”); 
  

	 	(ii)	for drafts which are not depository bills, to sign for and on behalf and in the name of the Canadian Borrower as drawer and to endorse on its behalf, Bankers’ Acceptances drawn
on the Canadian Lender payable to the order of the undersigned or payable to the order of such Canadian Lender; 

  

	 	(iii)	to fill in the amount, date and maturity date of such Bankers’ Acceptances; and 

  

	 	(iv)	to deposit and/or deliver such Bankers’ Acceptances which have been accepted by such Canadian Lender, 

 provided that such acts in each case are to be undertaken by the Canadian Lender in question strictly in accordance with instructions given to such
Canadian Lender by the Canadian Borrower as provided in this Section. For certainty, signatures of any authorized signatory of a Canadian Lender may be mechanically reproduced in facsimile on Bankers’ Acceptances in accordance herewith and such
facsimile signatures shall be binding and effective as if they had been manually executed by such authorized signatory of such Canadian Lender. The communication in writing by the Canadian Borrower, or on behalf of the Canadian Borrower by the
Canadian Agent, to the Canadian Lender of the instructions set out in the Bankers’ Acceptance Notice shall constitute (a) the authorization and instruction of the Canadian Borrower to the Canadian Lender to sign for and on behalf and in
the name of the Canadian Borrower as drawer the requested Bankers’ Acceptances and to complete and/or endorse Bankers’ Acceptances in accordance with such information as set out above and (b) the request of the Canadian Borrower to
the Canadian Lender to accept such Bankers’ Acceptances and deposit the same with the clearing house or deliver the same, as the case may be, in each case in accordance with this Agreement and such instructions. The Canadian Borrower
acknowledges that a Canadian Lender shall not be obligated to accept any such Bankers’ Acceptances except in accordance with the provisions of this Agreement. A Canadian Lender shall be and it is hereby authorized to act on behalf of the
Canadian Borrower upon and in compliance with instructions communicated to that Canadian Lender as provided herein if the Canadian Lender reasonably believes such instructions to be genuine. If a Canadian Lender accepts Bankers’ Acceptances
pursuant to any such instructions, that Canadian Lender shall confirm particulars of such instructions and advise the Canadian Agent that it has complied therewith by notice in writing addressed to the Canadian Agent and served personally or sent by
telecopier in accordance with the provisions hereof. A Canadian Lender’s actions in compliance with such instructions, confirmed and advised to the Canadian Agent by such notice, shall be conclusively deemed to have been in accordance with the
instructions of the Canadian Borrower. This power of attorney may be revoked by the Canadian Borrower with respect to any particular Canadian Lender at any time upon not less than five (5) Banking Days’ prior written notice served upon the
Canadian Lender in question and the Canadian Agent, 
  

 36 

 provided that no such revocation shall reduce, limit or otherwise affect the obligations of the Canadian
Borrower in respect of any Bankers’ Acceptance executed, completed, endorsed, deposited and/or delivered in accordance herewith prior to the time at which such revocation becomes effective. 
 (6) If the power of attorney in Section 2.3(a)(5) is revoked with respect to any Canadian Lender, the Canadian Borrower shall,
from time to time as required by the applicable Canadian Lenders, provide to the Canadian Agent for delivery to each such Canadian Lender drafts drawn in blank by the Canadian Borrower (pre-endorsed and otherwise in fully negotiable form, if
applicable) in quantities sufficient for each such Canadian Lender to fulfill its obligations hereunder. Any such pre-signed drafts which are delivered by the Canadian Borrower to the Canadian Agent or a Canadian Lender shall be held in safekeeping
by the Canadian Agent or such Canadian Lender, as the case may be, with the same degree of care as if they were the Canadian Agent’s or such Canadian Lender’s property, and shall only be dealt with by the Canadian Lenders and the Canadian
Agent in accordance herewith. No Canadian Lender shall be responsible or liable for its failure to make its share of any Bankers’ Acceptances required hereunder if the cause of such failure is, in whole or in part, due to the failure of the
Canadian Borrower to provide such pre-signed drafts to the Canadian Agent (for delivery to such Canadian Lender) on a timely basis. 
 (7) Promptly following receipt of a Bankers’ Acceptance Notice, the Canadian Agent shall so advise the Canadian Lenders and shall advise each Canadian Lender of the face amount of each Bankers’ Acceptance to be accepted by it and
the term thereof. The aggregate face amount of Bankers’ Acceptances to be accepted by a Canadian Lender shall be determined by the Canadian Agent by reference to the respective Canadian Commitments of the Canadian Lenders, except that, if the
face amount of a Bankers’ Acceptance, which would otherwise be accepted by a Canadian Lender, would not be C$100,000.00 or an integral multiple thereof, such face amount shall be increased or reduced by the Canadian Agent in its sole and
unfettered discretion to the nearest integral multiple of C$100,000.00. 
 (8) Each Bankers’ Acceptance to be accepted by
a Canadian Lender shall be accepted at such Canadian Lender’s office shown on the signature pages hereof or as otherwise designated by such Canadian Lender from time to time. 
 (9) On the relevant borrowing date, each Canadian Lender severally agrees to purchase from the Canadian Borrower, at the face amount
thereof discounted by the Applicable BA Discount Rate, any Bankers’ Acceptance accepted by it and provide to the Canadian Agent, for the account of the Canadian Borrower, the BA Discount Proceeds in respect thereof after deducting therefrom the
amount of the Acceptance Fee payable by the Canadian Borrower to such Canadian Lender under Section 2.3(c) in respect of such Bankers’ Acceptance. 
 (10) Each Canadian Lender may at any time and from time to time hold, sell, rediscount or otherwise dispose of any or all Bankers’
Acceptances accepted and purchased by it. 
  

 37 

 (11) The Canadian Borrower waives presentment for payment and any other defense to
payment of any amounts due to a Canadian Lender in respect of a Bankers’ Acceptance accepted by it pursuant to this Agreement which might exist solely by reason of such Bankers’ Acceptance being held, at the maturity thereof, by such
Canadian Lender in its own right and the Canadian Borrower agrees not to claim any days of grace if such Canadian Lender as holder sues the Canadian Borrower on the Bankers’ Acceptances for payment of the amount payable by the Canadian Borrower
thereunder. 
 (b) With respect to each Bankers’ Acceptance, the Canadian Borrower, prior to the occurrence and continuation of a
Default, may give irrevocable telephone or written notice (or such other method of notification as may be agreed upon between the Canadian Agent and the Canadian Borrower) to the Canadian Agent at or before 12:00 noon (Toronto, Ontario time) two
(2) Business Days prior to the maturity date of such Bankers’ Acceptance followed by written confirmation electronically transmitted to the Canadian Agent on the same day, of the Canadian Borrower’s intention to issue one or more
Bankers’ Acceptance on such maturity date (each a “Refunding Bankers’ Acceptance”) to provide for the payment of such maturing Bankers’ Acceptance (it being understood that payments by the Canadian Borrower and
fundings by the Canadian Lenders in respect of each maturing Bankers’ Acceptance and each related Refunding Bankers’ Acceptance shall be made on a net basis reflecting the difference between the face amount of such maturing Bankers’
Acceptance and the BA Discount Proceeds (net of the applicable Acceptance Fee) of such Refunding Bankers’ Acceptance). Any funding on account of any maturing Bankers’ Acceptance must be made at or before 12:00 noon (Toronto, Ontario time)
on the maturity date of such Bankers’ Acceptance. If the Canadian Borrower fails to give such notice and does not otherwise pay to the Canadian Agent all Bankers’ Acceptance Liabilities on the maturity date of any such Bankers’
Acceptance, then subject to satisfaction of the conditions in Section 5 hereof and to the Maximum Canadian Available Amount, the Canadian Borrower shall be irrevocably deemed to have requested and to have been advanced a Canadian Prime
Loan in the face amount of such maturing Bankers’ Acceptance on the maturity date of such Bankers’ Acceptance from the Canadian Lender which accepted such maturing Bankers’ Acceptance, which Canadian Prime Loan shall thereafter bear
interest as such in accordance with the provisions hereof until paid in full. 
 (c) An Acceptance Fee shall be payable by the Canadian
Borrower to each Canadian Lender in advance (in the manner specified in Section 2.3(a)(6)) in respect of, and as a condition precedent to the acceptance by such Canadian Lender of, a Bankers’ Acceptance to be accepted by such
Canadian Lender calculated at the rate per annum equal to the Margin Percentage applicable to LIBOR Borrowings, calculated on the face amount of such Bankers’ Acceptance and computed on the basis of the number of days in the term of such
Bankers’ Acceptance and a year of 365 days. 
 2.4 Terminations, Reductions or Reallocations of Commitments. 
 (a) Mandatory. On the Termination Date, all U.S. Commitments, Canadian Commitments and U.K. Commitments shall be terminated in their entirety.

  

 38 

 (b) Optional Termination or Reduction. U.S. Borrower, Canadian Borrower or U.K. Borrower, as the
case may be, shall have the right to terminate or reduce the unused portion of the U.S. Commitments, the Canadian Commitments or the U.K. Commitments, as the case may be, at any time or from time to time, provided that (i) U.S. Borrower,
Canadian Borrower or U.K. Borrower, as the case may be, shall give notice of each such termination or reduction to the appropriate Agent as provided in Section 4.3 hereof and (ii) each such partial reduction shall be in an integral
multiple of $1,000,000. Notwithstanding the foregoing, U.S. Borrower may not reduce the U.S. Commitments below the then outstanding principal balance of the U.S. Obligations, Canadian Borrower may not reduce the Canadian Commitments below the then
outstanding principal balance of the Canadian Obligations and U.K. Borrower may not reduce the U.K. Commitments below the then outstanding principal balance of the U.K. Obligations. No termination or reduction of the Commitments pursuant to this
provision may be reinstated without the prior written approval of Agents and the Lenders. 
 (c) Optional Increase. At any time after
the date hereof and so long as no Default or Event of Default shall have occurred which is continuing, U.S. Borrower shall have the right to increase the U.S. Commitments by an amount not exceeding $50,000,000, in the aggregate, provided that
(i) the U.S. Borrower shall give notice of each such increase to the U.S. Agent as provided in Section 4.3 hereof, (ii) no Lender shall be required to increase its U.S. Commitment unless it shall have expressly agreed to such
increase in writing (but otherwise, no notice to or consent by any Lender shall be required, notwithstanding anything to the contrary set forth in Section 11.5 hereof), (iii) the addition of new U.S. Lenders shall be subject to the
terms and provisions of Section 11.6 hereof as if such new U.S. Lenders were acquiring an interest in the U.S. Revolving Loans by assignment from an existing U.S. Lenders (to the extent applicable, i.e. required approvals, minimum
amounts, execution of new U.S. Revolving Notes and the like), (iv) the U.S. Borrower shall execute and deliver such additional or replacement U.S. Revolving Notes and such other documentation (including evidence of proper authorization) as may
be reasonably requested by the U.S. Agent, any new U.S. Lenders or any U.S. Lenders which is increasing its Commitment and (v) each such increase shall be in an aggregate amount of at least $5,000,000. If the U.S. Borrower shall terminate or
reduce the U.S. Commitments pursuant to Section 2.4(b) hereof, it shall have no further right to increase the U.S. Commitments pursuant to this Section. U.S. Borrower shall be required to pay (or to reimburse each applicable U.S. Lender
for) any breakage costs incurred by any U.S. Lender in connection with the need to reallocate existing U.S. Revolving Loans among the U.S. Lenders following any increase in the U.S. Commitments pursuant to this provision. 
 (d) Reallocations. Subject to agreement by the Borrowers, any Dual Lender may reallocate its existing U.S. Commitment and Canadian Commitment or
U.K. Commitment, as the case may be, so long as the sum of such U.S. Commitment and Canadian Commitment or U.K. Commitment, as the case may be, remains unchanged. In addition, with the prior written consent of all of the Dual Lenders, any U.S.
Lender may agree with Borrowers to convert a portion of its U.S. Commitment into a Canadian Commitment or a U.K. Commitment, thereby becoming a Dual Lender, any Canadian Lender may agree with Borrowers to convert a portion of its Canadian Commitment
into a U.S. Commitment and any U.K. Lender may agree with Borrowers to convert a portion of its U.K. Commitment into a U.S. Commitment, in each case so long as (i) each Lender continues to be a U.S. Lender with a U.S. Commitment of at least
$1,000,000 and (ii) the sum of such Lender’s U.S. Commitment and Canadian Commitment or U.K. 
  

 39 

 Commitment, as the case may be, remains equal to the aggregate amount of such Lender’s U.S. Commitment and Canadian
Commitment or U.K. Commitment, as the case may be, prior to such reallocation. Borrowers shall give written notice to the Agents of any reallocation pursuant to this provision at least ten (10) Business Days prior to the effective date of any
such reallocation. No Lender shall be required to agree to any such reallocation, but may do so at its option, in its sole discretion. The following conditions precedent must be satisfied prior to any such reallocation becoming effective:

 (1) no Default or Event of Default shall have occurred and be continuing; 
 (2) if, as a result of any such reallocation, the aggregate U.S. Obligations would exceed the aggregate of all of the U.S. Commitments,
then the U.S. Borrower shall, on the effective date of such reallocation, repay or prepay U.S. Revolving Loans (or provide Cover for Letter of Credit Liabilities relating to U.S. Letters of Credit) in accordance with this Agreement in an aggregate
principal amount such that, after giving effect thereto, the aggregate U.S. Obligations shall not exceed the aggregate of all of the U.S. Commitments; 
 (3) if, as a result of any such reallocation, the Canadian Obligations would exceed the aggregate of all of the Canadian Commitments, then the Canadian Borrower shall, on the effective date of such reallocation, repay
or prepay Canadian Revolving Loans (or provide Cover for Letter of Credit Liabilities relating to Canadian Letters of Credit or for Bankers’ Acceptance Liabilities) in accordance with this Agreement in an aggregate principal amount such that,
after giving effect thereto, the Canadian Obligations shall not exceed the aggregate of all of the Canadian Commitments; 
 (4) if, as a result of any such reallocation, the U.K. Obligations would exceed the aggregate of all of the U.K. Commitments, then the U.K. Borrower shall, on the effective date of such reallocation, repay or prepay U.K. Revolving Loans (or
provide Cover for Letter of Credit Liabilities relating to U.K. Letters of Credit) in accordance with this Agreement in an aggregate principal amount such that, after giving effect thereto, the U.K. Obligations shall not exceed the aggregate of all
of the U.K. Commitments; 
 (5) Borrowers shall have paid any amounts (or shall have provided Cover) due under Sections
2.9(c) or (d) hereof on the date of such reallocation; 
 (6) the Maximum Canadian Available Amount shall be
adjusted to equal the sum of all of the Canadian Commitments after giving effect to such reallocation, the Maximum U.K. Available Amount shall be adjusted to equal the sum of all of the U.K. Commitments after giving effect to such reallocation and
the Maximum U.S. Available Amount shall be adjusted to equal the sum of all of the U.S. Commitments after giving effect to such reallocation; 
 (7) participations by the Lenders in the outstanding Letters of Credit and the Letter of Credit Liabilities and the outstanding Loans of the Lenders shall be adjusted to give effect to such reallocation;
provided, however, that in lieu of requiring any 
  

 40 

 prepayment of any Bankers’ Acceptances in order to make appropriate adjustments to give effect to
such reallocations, Canadian Borrower shall be required to provide additional Cover for any applicable portion of the Bankers’ Acceptance Liabilities; 
 (8) each Lender whose U.S. Commitment, Canadian Commitment or U.K. Commitment shall be the subject of any reallocation shall have received from the Borrowers a fee equal to the greater of $3,000.00 or 1/16% of the
amount of the increase or decrease, as the case be, in its Canadian Commitment or U.K. Commitment, as the case may be. 
 (9)
No such reallocation may be effectuated if, as a result thereof, the aggregate amount of U.S. Obligations which are denominated in any Alternative Currencies would exceed $15,000,000. 
 2.5 Commitment Fees. 
 (a) U.S.
Borrower shall pay to U.S. Agent for the account of each U.S. Lender, Canadian Borrower shall pay to Canadian Agent for the account of each Canadian Lender and U.K. Borrower shall pay to U.K. Agent for the account of each U.K. Lender, commitment
fees for the Availability Period at a rate per annum equal to the Commitment Fee Percentage. Such commitment fees shall be computed (on the basis of the actual number of days elapsed in a year composed of 360 days) on each day and shall be based on
the excess of (x) the aggregate amount of each Lender’s U.S. Commitment, Canadian Commitment or U.K. Commitment, as the case may be, for such day over (y) the sum of (i) the aggregate unpaid principal balance (in Dollars) of such
Lender’s applicable Note or Notes on such day plus (ii) the aggregate applicable Letter of Credit Liabilities as to such Lender for such day plus, in the case of Canadian Lenders only, (iii) the aggregate Bankers’
Acceptance Liabilities outstanding on such day. Accrued commitment fees shall be payable in arrears on the Quarterly Dates prior to the Termination Date and on the Termination Date, with any Obligations which are denominated in any Alternative
Currency converted to Dollars at the Exchange Rate on each such date for the purposes of each such calculation. 
 (b) All past due fees
payable under this Section shall bear interest at the Past Due Rate. 
 2.6 Several Obligations. The failure of any Lender to make any
Loan to be made by it or to accept and purchase any Bankers’ Acceptance required to be so accepted and purchased by it on the date specified therefor shall not relieve any other Lender of its obligation to make its Loan or to accept and
purchase its Bankers’ Acceptance on such date, but neither any Agent nor any Lender shall be responsible or liable for the failure of any other Lender to make a Loan or to accept and purchase any Bankers’ Acceptance or to participate in,
or co-issue, any Letter of Credit. Notwithstanding anything contained herein to the contrary, (i) if a U.S. Lender fails to make a U.S. Revolving Loan as and when required hereunder, then upon each subsequent event which would otherwise result
in payments of principal being made to the defaulting U.S. Lender, the amount which would have been paid to the defaulting U.S. Lender shall be divided among the non-defaulting U.S. Lenders ratably according to their respective Commitment
Percentages until the Obligations of each U.S. Lender (including the defaulting U.S. Lender) are equal to 
  

 41 

 such U.S. Lender’s Commitment Percentage of the total U.S. Obligations, (ii) if a Canadian Lender fails to make
a Canadian Revolving Loan or accept and purchase any Bankers’ Acceptance as and when required hereunder, then upon each subsequent event which would otherwise result in payments of principal being made to the defaulting Canadian Lender, the
amount which would have been paid to the defaulting Canadian Lender shall be divided among the non-defaulting Canadian Lenders ratably according to their respective Commitment Percentages until the Obligations of each Canadian Lender (including the
defaulting Canadian Lender) are equal to such Canadian Lender’s Commitment Percentage of the total Canadian Obligations and (iii) if a U.K. Lender fails to make a U.K. Revolving Loan as and when required hereunder, then upon each
subsequent event which would otherwise result in payments of principal being made to the defaulting U.K. Lender, the amount which would have been paid to the defaulting U.K. Lender shall be divided among the non-defaulting U.K. Lenders ratably
according to their respective Commitment Percentages until the Obligations of each U.K. Lender (including the defaulting U.K. Lender) are equal to such U.K. Lender’s Commitment Percentage of the total U.K. Obligations. 
 2.7 Notes. The U.S. Revolving Loans made by each U.S. Lender shall be evidenced by a single U.S. Revolving Note of U.S. Borrower in substantially
the form of Exhibit D hereto payable to the order of such U.S. Lender in a principal amount equal to the U.S. Commitment of such U.S. Lender, and otherwise duly completed. The Canadian Revolving Loans made by each Canadian Lender shall be
evidenced by a single Canadian Revolving Note of Canadian Borrower in substantially the form of Exhibit C hereto payable to the order of such Canadian Lender in a principal amount equal to the Canadian Commitment of such Canadian Lender, and
otherwise duly completed. The U.K. Revolving Loans made by each U.K. Lender shall be evidenced by a single U.K. Revolving Note of U.K. Borrower in substantially the form of Exhibit H hereto payable to the order of such U.K. Lender in a
principal amount equal to the U.K. Commitment of such U.K. Lender, and otherwise duly completed. The promissory notes described in this Section are each, together with all renewals, extensions, modifications and replacements thereof and
substitutions therefor, called a “Note” and collectively called the “Notes”. Each Lender is hereby authorized by each Borrower to endorse on the schedule (or a continuation thereof) that may be attached to each Note of such
Lender, to the extent applicable, the date, amount, type of and the applicable period of interest for each Loan made by such Lender to the applicable Borrower hereunder, and the amount of each payment or prepayment of principal of such Loan received
by such Lender, provided, that any failure by such Lender to make any such endorsement shall not affect the obligations of any Borrower under such Note or hereunder in respect of such Loan. 
 2.8 Use of Proceeds. The proceeds of the Loans, of the Letters of Credit and of the acceptance and purchase of Bankers’ Acceptances shall be
used by the Borrowers to refinance existing Borrowed Money Indebtedness of the Borrowers and for acquisitions and for other working capital and general corporate purposes. Neither any Agent nor any Lender shall have any responsibility as to the use
of any proceeds of the Loans or of the acceptance and purchase of Bankers’ Acceptances. 
  

 42 

 2.9 Currency Fluctuations; Market Disruptions. 
 (a) Not later than 1:00 p.m. (Houston, Texas time) on each Calculation Date, the U.S. Agent shall determine the Exchange Rate applicable to each
applicable Alternative Currency as of such Calculation Date. For purposes of this Section, the Exchange Rate so determined shall become effective on the first Business Day immediately following the relevant Calculation Date (a “Reset
Date”). 
 (b) Not later than 4:00 p.m. (Houston, Texas time) on each Reset Date, the U.S. Agent shall consult with the other Agents
to determine the aggregate Canadian Obligations, the aggregate U.S. Obligations and the aggregate U.K. Obligations. 
 (c) If, on any Reset
Date or on the date of any reallocation of the U.S. Commitments, the Canadian Commitments and the U.K. Commitments pursuant to Section 2.4(c) hereof, the sum of the aggregate U.S. Obligations, the U.K. Obligations and the Canadian
Obligations exceeds the aggregate of all of the U.S. Commitments, the Canadian Commitments and the U.K. Commitments, then (i) the Agents shall give notice thereof to the Lenders and Borrowers and (ii) the Borrowers shall within two
(2) Business Days thereafter, repay or prepay Loans (or provide Cover for Letter of Credit Liabilities or Bankers’ Acceptance Liabilities) in accordance with this Agreement in an aggregate principal amount sufficient to reduce the sum of
the aggregate U.S. Obligations, the U.K. Obligations and the Canadian Obligations to the aggregate of all of the U.S. Commitments, the Canadian Commitments and the U.K. Commitments. 
 (d) If, on any day prior to the Termination Date, the U.S. Obligations exceed the aggregate of all of the U.S. Commitments, then (i) the U.S. Agent
shall give notice thereof to the U.S. Borrower and the U.S. Lenders and (ii) within two (2) Business Days thereafter, the U.S. Borrower shall repay or prepay U.S. Revolving Loans (or provide Cover for Letter of Credit Liabilities relating
to U.S. Letters of Credit) in accordance with this Agreement in an aggregate principal amount such that, after giving effect thereto, the U.S. Obligations shall not exceed the aggregate of all of the U.S. Commitments. If, on any day prior to the
Termination Date, the Canadian Obligations exceed the aggregate of all of the Canadian Commitments, then (i) the Canadian Agent shall give notice thereof to the Canadian Borrower and the Canadian Lenders and (ii) within two
(2) Business Days thereafter, the Canadian Borrower shall repay or prepay Canadian Revolving Loans (or provide Cover for Letter of Credit Liabilities relating to Canadian Letters of Credit or Bankers’ Acceptance Liabilities) in accordance
with this Agreement in an aggregate principal amount such that, after giving effect thereto, the Canadian Obligations shall not exceed the aggregate of all of the Canadian Commitments. If, on any day prior to the Termination Date, the U.K.
Obligations exceed the aggregate of all of the U.K. Commitments, then (i) the U.K. Agent shall give notice thereof to the U.S. Borrower and the U.K. Lenders and (ii) within two (2) Business Days thereafter, the U.K. Borrower shall
repay or prepay U.K. Revolving Loans (or provide Cover for Letter of Credit Liabilities relating to U.K. Letters of Credit) in accordance with this Agreement in an aggregate principal amount such that, after giving effect thereto, the U.K.
Obligations shall not exceed the aggregate of all of the U.K. Commitments. 
 (e) If at any time the aggregate amount of U.S. Obligations
which are denominated in any Alternative Currencies exceeds $15,000,000, the U.S. Agent may, by notice to the U.S., 
  

 43 

 Borrower, suspend the option of the U.S. Borrower to designate any Eurocurrency Borrowing denominated in any Alternative
Currency until such time as the aggregate amount of U.S. Obligations which are denominated in any Alternative Currencies shall be less than $15,000,000. 
 (f) Notwithstanding the satisfaction of all conditions referred to in the Loan Documents with respect to any Borrowing in any Alternative Currency, if there shall occur on or before the date of such Borrowing any
change in national or international financial, political or economic conditions or currency exchange rates or exchange controls which would in the reasonable opinion of the applicable Agent make it impracticable for such Borrowing to be denominated
in the applicable Alternative Currency, then the applicable Agent shall forthwith give notice thereof to the applicable Borrower and the applicable Lenders, and the request for such Borrowing shall be deemed to have been cancelled. If any applicable
Agent has notified the applicable Lenders and the applicable Borrower that a currency previously designated as an available Alternative Currency shall no longer be an available Alternative Currency, then promptly, but in any event within ten
(10) Business Days of receipt of such notice from the applicable Agent, the applicable Borrower shall repay all Loans in such affected currency or convert such Loans into Loans denominated in Dollars or in another Alternative Currency, all
subject to the other terms set forth in this Agreement. 
 3. Borrowings, Prepayments and Interest Options. 
 3.1 Borrowings. The applicable Borrower shall give the applicable Agent notice of each borrowing to be made hereunder as provided in
Section 4.3 hereof and the applicable Agent shall promptly notify each applicable Lender of such request. Not later than 11:00 a.m. Houston, Texas time (in the case of U.S. Revolving Loans which are same day fundings), 2:00 p.m. Houston,
Texas time (in the case of U.S. Revolving Loans which are not same day fundings), 11:00 a.m. Toronto, Ontario time (in the case of Canadian Revolving Loans which are same day fundings and Bankers’ Acceptances), 1:00 p.m. Toronto, Ontario time
(in the case of Canadian Revolving Loans which are not same day fundings), 11:00 a.m. London, United Kingdom time (in the case of U.K. Revolving Loans which are same day fundings) or 1:00 p.m. London, United Kingdom time (in the case of U.K.
Revolving Loans which are not same day fundings) on the date specified for each such borrowing hereunder, each applicable Lender shall make available the amount of the Loan, if any, to be made by it on such date and/or the proceeds of the acceptance
and purchase of any Bankers’ Acceptances, if any, to be so accepted and purchased by it on such date to the applicable Agent at its Principal Office, in immediately available funds, for the account of the applicable Borrower. Such amounts
received by the applicable Agent will be held in an account maintained by the applicable Borrower with the applicable Agent. The amounts so received by the applicable Agent shall, subject to the terms and conditions of this Agreement, be made
available to the applicable Borrower by wiring or otherwise transferring, in immediately available funds, such amount to an account designated by the applicable Borrower and approved by the applicable Agent. 
 3.2 Prepayments. 
 (a) Optional
Prepayments. Except as provided in Section 3.3 hereof, each Borrower shall have the right to prepay, on any Business Day, in whole or in part, without the payment of any premium, penalty or fee, any of the Obligations (other than
Obligations relating to Bankers’ 
  

 44 

 Acceptances) at any time or from time to time, provided that the applicable Borrower shall give the applicable
Agent notice of each such prepayment as provided in Section 4.3 hereof. Each optional prepayment shall be in an amount equal to $1,000,000 or an integral multiple of $100,000 in excess thereof in respect of Loans denominated in Dollars
or, if the Loans are denominated in any Alternative Currency, the approximate equivalent thereof in such Alternative Currency. Bankers’ Acceptances may not be prepaid. 
 (b) Mandatory Prepayments and Cover. Except, in each case, as provided in Section 3.3 hereof, 
 (1) Sale of Certain Assets. Within forty-five days after the receipt by U.S. Borrower or its applicable Subsidiary of proceeds from
the sale of assets outside of the ordinary course of business by U.S. Borrower or any of its Subsidiaries, an amount equal to the net proceeds (after taxes) in excess of (x) $2,000,000 (in any fiscal year) realized from the sale of assets
(other than real Property acquired after the date hereof) or (y) $3,000,000 (in any fiscal year) realized from the sale of real Property acquired after the date hereof minus the portion of such proceeds utilized to replace or acquire or
contractually committed to replace or acquire assets within such forty-five (45) day period shall be applied as a prepayment on the Loans. 
 (2) Equity Proceeds. Within forty-five (45) days after the receipt by U.S. Borrower of the proceeds realized from the issuance of any equity securities by U.S. Borrower in connection with any public
offering of equity securities, an amount equal to one hundred percent (100%) of the net proceeds (after taxes) realized from such issuance minus the portion of such proceeds utilized to replace or acquire or contractually committed to
replace or acquire assets within such forty-five (45) day period shall be applied as a prepayment on the Loans. 
 (c) Interest
Payments. Accrued and unpaid interest on the unpaid principal balance of the Loans shall be due and payable on the Interest Payment Dates. 
 (d) Payments and Interest on Reimbursement Obligations. Each Borrower will pay to the applicable Agent for the account of each applicable Lender the amount of each Reimbursement Obligation owed by such Borrower. Such payment shall be
due on the date on which the applicable Agent notifies the applicable Borrower of the date and amount of the applicable payment by an Issuer of any drawing under a Letter of Credit or on the date of maturity of any Bankers’ Acceptance. The
amount of any Reimbursement Obligation may, if the applicable conditions precedent specified in Sections 5.1 and 5.2 hereof have been satisfied, be paid with the proceeds of Loans or, in the case of Canadian Obligations, of the
acceptance and purchase or Bankers’ Acceptances. Subject to Section 11.7 hereof, each Borrower will pay to the applicable Agent for the account of each applicable Lender interest on any Reimbursement Obligation at the Base Rate plus
the applicable Margin Percentage from the date such Reimbursement Obligation arises until the date five (5) Business Days thereafter and (ii) at the applicable Past Due Rate thereafter until the same is paid in full. 
  

 45 

 3.3 Interest Options 
 (a) Options Available. The outstanding principal balance of the Notes shall bear interest at the applicable Base Rate; provided, that (1) all past due amounts, both principal and accrued interest,
shall bear interest at the Past Due Rate, and (2) subject to the provisions hereof, each Borrower shall have the option of having all or any portion of the principal balances of its Notes from time to time outstanding bear interest at a
Eurocurrency Rate. The records of Agents and each of the Lenders with respect to Interest Options, Interest Periods and the amounts of Loans to which they are applicable shall be binding and conclusive, absent manifest error. Interest on the amount
of each advance against the Notes shall be computed on the amount of that advance and from the date it is made. Notwithstanding anything in this Agreement to the contrary, for the full term of the Notes the interest rate produced by the aggregate of
all sums paid or agreed to be paid to the holders of the Notes for the use, forbearance or detention of the debt evidenced thereby (including all interest on the Notes at the Stated Rate plus the Additional Interest) shall not exceed the Ceiling
Rate. Except for Borrowings made by way of Bankers’ Acceptances, Canadian Prime Loans and U.K. Prime Loans as herein provided, all Base Rate Borrowings shall be made in Dollars. 
 (b) Designation and Conversion. Each Borrower shall have the right to designate or convert its Interest Options in accordance with the provisions
hereof. Provided no Event of Default has occurred and is continuing and subject to the last sentence of Section 3.3(a) and the provisions of Section 3.3(c), each Borrower may elect to have a Eurocurrency Rate apply or
continue to apply to all or any portion of the principal balance of its Notes. Each change in Interest Options shall be a conversion of the rate of interest applicable to the specified portion of the Loans, but such conversion shall not change the
respective outstanding principal balances of the applicable Notes. The Interest Options shall be designated or converted in the manner provided below: 
  

	 	(i)	The applicable Borrower shall give the applicable Agent telephonic notice, promptly confirmed by a Rate Designation Notice (and the applicable Agent shall promptly inform each
applicable Lender thereof). Each such telephonic and written notice shall specify the amount of the Loan (in Dollars or, if applicable, in the applicable Alternative Currency with the Dollar amount thereof calculated using the then current Exchange
Rate) and type (i.e. U.S. Revolving Loan, Canadian Revolving Loan or U.K. Revolving Loan) which is the subject of the designation, if any; the amount of borrowings which are to be converted or for which an Interest Option is designated; the proposed
date for the designation or conversion and the Interest Period or Periods, if any, selected by the applicable Borrower. Such telephonic notice shall be irrevocable and shall be given to the applicable Agent no later than the applicable Rate
Designation Date. 

  

	 	(ii)	No more than six (6) LIBOR Borrowings shall be in effect with respect to the U.S. Revolving Loans at any time, no more than six (6) LIBOR Borrowings shall be in effect
with respect to the Canadian Revolving Loans at any time and no more than six (6) LIBOR Borrowings shall be in effect with respect to the U.K. Revolving Loans at any time. No single LIBOR Borrowing may include any combination of any two or more
of U.S. Revolving Loans, Canadian Revolving Loans and U.K. Revolving Loans. 

  

 46 

	 	(iii)	Each designation or conversion of a LIBOR Borrowing shall occur on a Business Day. 

  

	 	(iv)	Except as provided in Section 3.3(c) hereof, no LIBOR Borrowing may be converted to a Base Rate Borrowing or another LIBOR Borrowing on any day other than the last day
of the applicable Interest Period. 

  

	 	(v)	Each request for a LIBOR Borrowing shall be in the amount equal to $1,000,000 or an integral multiple of $100,000 in excess thereof. 

  

	 	(vi)	Each designation of an Interest Option with respect to the U.S. Revolving Notes shall apply to all of the U.S. Revolving Notes ratably in accordance with their respective
outstanding principal balances. Each designation of an Interest Option with respect to the Canadian Revolving Notes shall apply to all of the Canadian Revolving Notes ratably in accordance with their respective outstanding principal balances. Each
designation of an Interest Option with respect to the U.K. Revolving Notes shall apply to all of the U.K. Revolving Notes ratably in accordance with their respective outstanding principal balances. If any Lender assigns an interest in any of its
Notes when any LIBOR Borrowing is outstanding with respect thereto, then such assignee shall have its ratable interest in such LIBOR Borrowing. 

 (c) Special Provisions Applicable to LIBOR Borrowings. 
 (i) Options Unlawful. If the adoption
of any applicable Legal Requirement after the Effective Date or any change after the Effective Date in any applicable Legal Requirement or in the interpretation or administration thereof by any Governmental Authority or compliance by any Lender with
any request or directive (whether or not having the force of law) issued after the Effective Date by any central bank or other Governmental Authority shall at any time make it unlawful or impossible for any Lender to permit the establishment of or
to maintain any LIBOR Borrowing, the commitment of such Lender to establish such LIBOR Borrowing shall forthwith be canceled and the applicable Borrower shall forthwith, on the last day of the Interest Period relating to any outstanding LIBOR
Borrowing (or within such earlier period as may be required by applicable law) (1) convert the LIBOR Borrowing of such Lender with respect to which such demand was made to a Base Rate Borrowing; (2) pay all accrued and unpaid interest to
date on the amount so converted; and (3) pay any amounts required to compensate each Lender for any additional cost or expense which any Lender may incur as a result of such adoption of or change in such Legal Requirement or in the
interpretation or administration thereof and any Funding Loss which any Lender may incur as a result of such conversion. If, when any Agent so notifies any Borrower, such Borrower has given a Rate Designation Notice specifying a LIBOR Borrowing but
the selected Interest Period has not yet begun, as to the applicable Lender such Rate Designation Notice shall be deemed to be of no force and effect, as if never made, and the balance of the Loans made by such Lender specified in such Rate
Designation Notice shall bear interest at the Base Rate until a different available Interest Option shall be designated in accordance herewith. 
  

 47 

 (ii) Increased Cost of Borrowings. Subject to Section 11.17, if the adoption after the
Effective Date of any applicable Legal Requirement or any change after the Effective Date in any applicable Legal Requirement or in the interpretation or administration thereof by any Governmental Authority or compliance by any Lender with any
request or directive (whether or not having the force of law) issued after the Effective Date by any central bank or Governmental Authority shall at any time as a result of any portion of the principal balances of the Notes being maintained on the
basis of a Eurocurrency Rate: 
  

	 	(1)	subject any Lender to any Taxes, or any deduction or withholding for any Taxes, on or from any payment due under any LIBOR Borrowing or other amount due hereunder, other than income
and franchise taxes of the United States or its political subdivisions or such other jurisdiction in which the applicable Lender has its principal office or applicable lending office; or 

  

	 	(2)	change the basis of taxation of payments due from any Borrower to any Lender under any LIBOR Borrowing (otherwise than by a change in the rate of taxation of the overall net income
of such Lender); or 

  

	 	(3)	impose, modify, increase or deem applicable any reserve requirement (excluding that portion of any reserve requirement included in the calculation of the applicable Eurocurrency
Rate), special deposit requirement or similar requirement (including, but not limited to, state law requirements) against assets of any Lender, or against deposits with any Lender, or against loans made by any Lender, or against any other funds,
obligations or other Property owned or held by any Lender; or 

  

	 	(4)	impose on any Lender any other condition regarding any LIBOR Borrowing; 

 and the result of any of the foregoing is to increase the cost to any Lender of agreeing to make or of making, renewing or maintaining such LIBOR Borrowing, or reduce the amount of principal or interest received by any Lender, then, within
15 Business Days after demand by any Agent (accompanied by a statement setting forth in reasonable detail the applicable Lender’s basis therefor), the applicable Borrower shall pay to the applicable Agent additional amounts which shall
compensate each Lender for such increased cost or reduced amount. The reasonable, good faith determination by any Lender of the amount of any such increased cost, increased reserve requirement or reduced amount shall be conclusive and binding,
absent manifest error. Each Borrower shall have the right, if it receives from any Agent any notice referred to in this paragraph, upon three Business Days’ notice to the applicable Agent (which shall notify each affected Lender), either
(i) to repay in full (but not in part) any borrowing with respect to which such notice was given, together with any accrued interest thereon, or (ii) to convert the LIBOR Borrowing which is the subject of the notice to a Base Rate
Borrowing; provided, that any such repayment or conversion shall be accompanied by payment of (x) the amount required to 
  

 48 

 compensate each Lender for the increased cost or reduced amount referred to in the preceding paragraph; (y) all
accrued and unpaid interest to date on the amount so repaid or converted; and (z) any Funding Loss which any Lender may incur as a result of such repayment or conversion. Each Lender will notify the applicable Borrower through the applicable
Agent of any event occurring after the date of this Agreement which will entitle such Lender to compensation pursuant to this Section as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, and (if
so requested by the applicable Borrower through the applicable Agent) will designate a different lending office of such Lender for the applicable LIBOR Borrowing or will take such other action as the applicable Borrower may reasonable request if
such designation or action is consistent with the internal policy of such Lender and legal and regulatory restrictions, will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be
disadvantageous to such Lender. 
 (iii) Inadequacy of Pricing and Rate Determination. If, for any reason with respect to any Interest
Period, the applicable Agent (or, in the case of clause 3 below, the applicable Lender) shall have reasonably and in good faith determined (which determination shall be conclusive and binding upon the applicable Borrower, absent manifest
error) that: 
  

	 	(1)	such Agent is unable through its customary general practices to determine any applicable Eurocurrency Rate, or 

  

	 	(2)	by reason of circumstances affecting the applicable market, generally, such Agent is not being offered deposits in United States dollars or in the applicable Alternative Currency,
as the case may be, in such market, for the applicable Interest Period and in an amount equal to the amount of any applicable LIBOR Borrowing requested by the applicable Borrower, or 

  

	 	(3)	any applicable Eurocurrency Rate will not adequately and fairly reflect the cost to any Lender of making and maintaining such LIBOR Borrowing hereunder for any proposed Interest
Period, 

 then the applicable Agent shall give the applicable Borrower notice thereof and thereupon, (A) any Rate Designation Notice
previously given by such Borrower designating the applicable LIBOR Borrowing which has not commenced as of the date of such notice from such Agent shall be deemed for all purposes hereof to be of no force and effect, as if never given, and
(B) until the applicable Agent shall notify such Borrower that the circumstances giving rise to such notice from such Agent no longer exist, each Rate Designation Notice requesting the applicable Eurocurrency Rate shall be deemed a request for
a Base Rate Borrowing, and any applicable LIBOR Borrowing then outstanding shall be converted, without any notice to or from the applicable Borrower, upon the termination of the Interest Period then in effect with respect to it, to a Base Rate
Borrowing. 
 (iv) Funding Losses. Each Borrower shall indemnify each applicable Lender against and hold each applicable Lender
harmless from any Funding Loss relating to Loans to such Borrower or relating to Bankers’ Acceptances requested by such Borrower. Subject to Section 11.17, this indemnity shall survive the payment of the Notes. Within 15 Business
Days after 
  

 49 

 demand by any Agent (accompanied by a certificate of the applicable Lender setting forth in reasonable detail the amount
and calculation of the amount claimed as to any Funding Losses, which shall be conclusive and binding upon the applicable Borrower, absent manifest error), the applicable Borrower shall pay to such Agent, for the account of such Lender, the amount
of such Funding Losses. 
 (d) Funding Offices; Adjustments Automatic; Calculation Year. Any Lender may, if it so elects, fulfill its
obligation as to any LIBOR Borrowing by causing a branch or affiliate of such Lender to make such Loan and may transfer and carry such Loan at, to or for the account of any branch office or affiliate of such Lender; provided, that in such
event for the purposes of this Agreement such Loan shall be deemed to have been made by such Lender and the obligation of the applicable Borrower to repay such Loan shall nevertheless be to such Lender and shall be deemed held by it for the account
of such branch or affiliate. Without notice to any Borrower or any other Person, each rate required to be calculated or determined under this Agreement shall automatically fluctuate upward and downward in accordance with the provisions of this
Agreement. Interest at the Canadian Prime Rate, the U.K. Prime Rate or any applicable Prime Rate shall be computed on the basis of the actual number of days elapsed in a year consisting of 365 or 366 days, as the case may be. All other interest
required to be calculated or determined under this Agreement shall be computed on the basis of the actual number of days elapsed in a year consisting of 360 days, unless the Ceiling Rate would thereby be exceeded, in which event, to the extent
necessary to avoid exceeding the Ceiling Rate, the applicable interest shall be computed on the basis of the actual number of days elapsed in the applicable calendar year in which accrued. 
 (e) Funding Sources. Notwithstanding any provision of this Agreement to the contrary, each Lender shall be entitled to fund and maintain its
funding of all or any part of the Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Lender had actually funded and maintained each LIBOR
Borrowing during each Interest Period through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the Eurocurrency Rate for such Interest Period. 
 4. Payments; Pro Rata Treatment; Computations, Etc. 
 4.1 Payments. 
 (a) Except to the extent otherwise provided herein, all payments of principal, interest, Reimbursement
Obligations and other amounts to be made by any Borrower hereunder, under the Notes and under the other Loan Documents shall be made, without set-off or counterclaim, in (i) with respect to Bankers’ Acceptance Liabilities and Canadian
Prime Loans, Canadian Dollars, (ii) with respect to U.K. Prime Loans, Pounds or Euros, as the case may be, and (iii) in all other cases, in Dollars or in the applicable Alternative Currency, in immediately available funds, to the
applicable Agent at its Principal Office (or in the case of a successor U.S. Agent, at the principal office of such successor U.S. Agent in the United States, in the case of a successor Canadian Agent, at the principal office of such successor
Canadian Agent in Canada and in the case of a successor U.K. Agent, at the principal office of such successor U.K. Agent in the United Kingdom), not later than 11:00 a.m. Houston, Texas time (in the case of any payment by the U.S. 
  

 50 

 Borrower), 12:00 noon Toronto, Ontario time (in the case of any payment by the Canadian Borrower) or 11:00 a.m. London,
United Kingdom time (in the case of any payment by the U.K. Borrower) on the date on which such payment shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day).
With respect to payments made in Alternative Currencies, any applicable Agent may designate an alternative office to which such payments should be made so long as such alternative payment office shall be reasonably accessible to the applicable
Borrower. If currency control or exchange regulations are imposed in the country which issues any applicable Alternative Currency with the result that such Alternative Currency no longer exists or the applicable Borrower is not able to make payment
in such Alternative Currency, then all payments to be made by the applicable Borrower hereunder in such Alternative Currency shall instead be made when due in Dollars in an amount equal to the Dollar Amount (as of the date of repayment) of such
payment due, it being the intention of the parties hereto that the Borrowers take all risks of the imposition of any such currency control or exchange regulations. 
 (b) Each Borrower shall, at the time of making each payment hereunder, under any Note or under any other Loan Document, specify to the applicable Agent the Obligations payable by such Borrower hereunder or thereunder
to which such payment is to be applied. Each payment received by any Agent hereunder, under any Note or under any other Loan Document for the account of a Lender shall be paid promptly to such Lender, in immediately available funds. If any Agent
fails to send to any Lender the applicable amount by the close of business on the date any such payment is received by such Agent if such payment is received prior to 11:00 a.m. Houston, Texas time (in the case of any payment to a U.S. Lender) or
12:00 noon Toronto, Ontario time (in the case of any payment to a Canadian Lender) or 11:00 a.m. London, United Kingdom time (in the case of any payment to a U.K. Lender) (or on the next succeeding Business Day with respect to payments which are
received after such time), such Agent shall pay to the applicable Lender interest on such amount from such date at a rate of interest per annum equal to (i) in respect of Obligations which are denominated in Dollars or in any Alternative
Currency, the Federal Funds Rate and (ii) in respect of Canadian Obligations which are denominated in Canadian Dollars, the CDOR Rate. Borrowers, Lenders and Agents acknowledge and agree that this provision and each other provision of this
Agreement or any of the other Loan Documents relating to the application of amounts in payment of the Obligations shall be subject to the provisions of Section 4.2(d) regarding pro rata application of amounts after an Event
of Default shall have occurred and be continuing. 
 (c) If the due date of any payment hereunder or under any other Loan Document falls on a
day which is not a Business Day, the due date for such payments (except as otherwise provided in clause (2) of the definition of “Interest Period”) shall be extended to the next succeeding Business Day and interest shall be
payable for any principal so extended for the period of such extension. 
 (d) All payments by any Borrower hereunder or under any other Loan
Document shall be made free and clear of and without deduction for or on account of any present or future income, stamp, or other taxes, fees, duties, withholding or other charges of any nature whatsoever imposed by any taxing authority excluding in
the case of each Agent, each Issuer and each Lender taxes imposed on or measured by its net income or franchise taxes imposed by the jurisdiction in which it is organized or through which it acts for purposes of this Agreement 
  

 51 

 (such non-excluded items being hereinafter referred to as “Taxes”). If any withholding or deduction from
any payment to be made to, or for the account of, any Agent, any Issuer or any Lender by any Borrower hereunder or under any other Loan Document is required in respect of any Taxes pursuant to any applicable law, rule, or regulation, then such
Borrower will (i) pay to the relevant authority the full amount required to be so withheld or deducted; (ii) to the extent available, promptly forward to the applicable Agent an official receipt or other documentation reasonably
satisfactory to such Agent evidencing such payment to such authority; and (iii) pay to the applicable Agent, for the account of each affected Person, such additional amount or amounts as are necessary to ensure that the net amount actually
received by such Person will equal the full amount such Lender would have received had no such withholding or deduction been required. Each such Person shall reasonably and in good faith determine such additional amount or amounts payable to it
(which determination shall, in the absence of manifest error, be conclusive and binding on each Borrower). If any Agent, any Issuer or any Lender becomes aware that any such withholding or deduction from any payment to be made by any Borrower
hereunder or under any other Loan Document is required, then such Person shall promptly notify the applicable Agent and the applicable Borrower thereof stating the reasons therefor and the additional amount required to be paid under this Section.
Each Lender shall execute and deliver to the applicable Agent and the applicable Borrower such forms as it may be required to execute and deliver pursuant to Section 11.13 hereof. To the extent that any such withholding or deduction
results from a breach of a representation by a Lender set forth herein or from the failure of a Lender to provide a form required by Section 11.13 hereof (unless such failure is due to some prohibition under applicable Legal
Requirements), the applicable Borrower shall have no obligation to pay the additional amount required by clause (iii) above. Anything in this Section notwithstanding, if any Lender elects to require payment by any Borrower of any
material amount under this Section, the applicable Borrower may, within 60 days after the date of receiving notice thereof and so long as no Default shall have occurred and be continuing, elect to terminate such Lender as a party to this Agreement;
provided that, concurrently with such termination the applicable Borrower shall (i) if the Agents and each of the other Lenders shall consent, pay that Lender all principal, interest and fees and other amounts owed to such Lender through
such date of termination or (ii) have arranged for another financial institution approved by the Agents (such approval not to be unreasonably withheld or delayed) as of such date, to become a substitute Lender for all purposes under this
Agreement in the manner provided in Section 11.6; provided further that, prior to substitution for any Lender, the applicable Borrower shall have given written notice to the Agents of such intention and the Lenders shall have the
option, but no obligation, for a period of 60 days after receipt of such notice, to increase their U.S. Commitments, Canadian Commitments or U.K. Commitments, as the case may be, in order to replace the affected Lender in lieu of such substitution.

 4.2 Pro Rata Treatment. Except to the extent otherwise provided herein: (a) each borrowing from the Lenders under
Section 2.1 hereof shall be made (w) in the case of Canadian Revolving Loans, ratably from the Canadian Lenders in accordance with their respective Canadian Commitments, (x) in the case of U.K. Revolving Loans, ratably from the
U.K. Lenders in accordance with their respective U.K. Commitments and (y) in the case of U.S. Revolving Loans, ratably from the U.S. Lenders in accordance with their respective U.S. Commitment; (b) each payment of commitment fees shall be
made for the account of the Lenders, and each termination or reduction of the U.S. Commitments, Canadian Commitments or U.K. Commitments of the Lenders under Section 2.3 hereof shall be applied, pro rata, according to the 
  

 52 

 Lenders’ respective U.S. Commitments, Canadian Commitments or U.K. Commitments, as the case may be; (c) each
payment by any Borrower of principal of or interest on the Canadian Revolving Loans, U.K. Revolving Loans, U.S. Revolving Loans or any Bankers’ Acceptance, as the case may be, prior to the occurrence of an Event of Default (or after the
applicable Event of Default shall have been fully cured or waived) shall be made to the applicable Agent for the account of the applicable Lenders pro rata in accordance with the respective unpaid principal amounts of the Canadian Revolving Loans,
U.K. Revolving Loans or U.S. Revolving Loans (as the case may be) held by or Bankers’ Acceptances accepted by such Lenders; (d) each payment by any Borrower of principal of or interest on the Canadian Revolving Loans, U.K. Revolving Loans,
U.S. Revolving Loans or any Bankers’ Acceptance, as the case may be, while an Event of Default shall have occurred and be continuing, shall be made to the applicable Agent for the account of the Lenders pro rata in accordance with the
respective unpaid principal amounts of the Obligations held by the Lenders (i.e. such payments shall be shared by all of the Lenders and not restricted to the holders of U.S. Revolving Notes, Canadian Revolving Notes or U.K. Revolving Notes, or
Lenders having accepted Bankers’ Acceptances, as the case may be, regardless of any attempted contrary designation by any Borrower); and (e) the applicable Lenders (other than the applicable Issuer) shall purchase from the applicable
Issuer participations in each Letter of Credit to the extent of their respective Commitment Percentages. 
 4.3 Certain Actions, Notices,
Etc. Notices to the applicable Agent of any termination or reduction of U.S. Commitments, Canadian Commitments or U.K. Commitments, as the case may be, and of borrowings and optional prepayments of Loans and requests for issuances of Letters of
Credit shall be irrevocable and shall be effective only if received by the applicable Agent not later than noon Houston, Texas time (in the case of U.S. Revolving Loans which are same day fundings), 11:00 a.m. Houston, Texas time (in the case of

Commitment or U.K. Commitment to be terminated or reduced. Each such notice of borrowing or prepayment shall specify the amount of the Loans to be borrowed or prepaid and the date of borrowing or prepayment (which shall be a Business Day). The
applicable Agent shall promptly notify the affected Lenders of the contents of each such notice. 
 4.4 Non-Receipt of Funds by Any
Agent. Unless the applicable Agent shall have been notified by a Lender or a Borrower (the “Payor”) prior to the date on which such Lender is to make payment to such Agent of the proceeds of a Loan (or funding of a drawing under a
Letter of Credit or reimbursement with respect to any drawing under a Letter of Credit or funding of a payment under a Bankers’ Acceptance or reimbursement with respect to any payment under a Bankers’ Acceptance) to be made by it hereunder
or the applicable Borrower is to make a payment to such Agent for the account of one or more of the Lenders, as the case may be (such payment being herein called the “Required Payment”), which notice shall be effective upon receipt, that
the Payor does not intend to make the Required Payment to such Agent, the applicable Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available
to the intended recipient on such date and, if the Payor has not in fact made the Required Payment to such Agent, the recipient of such payment (or, if such recipient is the beneficiary of a Letter of Credit, the applicable Borrower and, if such
Borrower fails to pay the amount thereof to the applicable Agent forthwith upon demand, the applicable Lenders ratably in proportion to their respective Commitment Percentages) shall, on demand, pay to such Agent the amount made available by such
Agent, together with interest thereon in respect of the period commencing on the date such amount was so made available by such Agent until the date Agent recovers such amount at a rate per annum for such period equal to (i) in respect of
Obligations which are denominated in Dollars or any Alternative Currency, the Federal Funds Rate and (ii) in respect of Canadian Obligations which are denominated in Canadian Dollars, the CDOR Rate. 
  

 54 

 4.5 Sharing of Payments, Etc. If a Lender shall obtain payment of any principal of or interest on
any Loan made by it under this Agreement, on any Reimbursement Obligation or on any other Obligation then due to such Lender hereunder, through the exercise of any right of set-off (including, without limitation, any right of setoff or Lien granted
under Section 9.2 hereof), banker’s lien, counterclaim or similar right, or otherwise, it shall promptly purchase from the other Lenders participations in the Loans made, or Reimbursement Obligations or other Obligations held, by
the other Lenders in such amounts, and make such other adjustments from time to time as shall be equitable to the end that all the Lenders shall share the benefit of such payment (net of any expenses which may be incurred by such Lender in obtaining
or preserving such benefit) pro rata in accordance with the unpaid Obligations then due to each of them. To such end all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such
payment is rescinded or must otherwise be restored. Each Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any Lender so purchasing a participation in the Loans made, or Reimbursement Obligations or other
Obligations held, by other Lenders may exercise all rights of set-off, bankers’ lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans, Reimbursement Obligations or other
Obligations in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to
any other indebtedness or obligation of any Borrower. 
 5. Conditions Precedent. 
 5.1 Initial Loans, Letters of Credit and Bankers’ Acceptances. The obligation of each Lender or each Issuer to make its initial Loans or issue

of its Board of Directors authorizing the transactions contemplated thereby), and (iii) such certificates as may be appropriate to demonstrate the qualification and good standing of each Obligor in the jurisdiction of its organization and in

to which it is a party related to any Loan, the issuance of any Letter of Credit or the acceptance of any Bankers’ Acceptance and (ii) who will, until replaced by other officer(s) or other authorized individual(s) duly authorized

  

 55 

 for that purpose, act as its representative for the purposes of signing documents and giving notices and other

Agent may require) of any prior Liens which are not permitted hereunder.

hazard insurance and, to the extent reasonably required by U.S. Agent with respect to Property covered by any Mortgage a policy or policies of title insurance issued by a nationally recognized title insurance company, insuring the Lien of each such
Mortgage as a valid first Lien on the Property described therein, free of any other Liens except as permitted hereunder, together with such endorsements, coinsurance and reinsurance as the U.S. Agent may reasonably request, and such surveys,
abstracts and appraisals as may be required pursuant to such Mortgages or as the U.S. Agent may reasonably request. 
 (l) Other
Documents. Agents shall have received such other documents consistent with the terms of this Agreement and relating to the transactions contemplated hereby as Agents may reasonably request. 
 5.2 All Loans, Letters of Credit and Bankers’ Acceptances. The obligation of each Lender to make any Loan to be made by it hereunder or to
issue or participate in any Letter of Credit or to accept and purchase any Bankers’ Acceptance is subject to (a) the accuracy, in all material respects, on the date of such Loan or such issuance or such acceptance and purchase of all

 6. Representations
and Warranties. 
 To induce Agents, the Issuers and the Lenders to enter into this Agreement and to make the Loans and issue or
participate in the Letters of Credit and accept and purchase Bankers’ Acceptances, U.S. Borrower, Canadian Borrower and U.K. Borrower each represents and warrants (such representations and warranties to survive any investigation and the making
of the Loans and the issuance of any Letters of Credit and the acceptance and purchase of any Bankers’ Acceptances) to the Lenders, Issuers and Agents as follows: 
 6.1 Organization. Each Obligor (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization; (b) has all necessary power and authority to conduct
its business as presently conducted; and (c) is duly qualified to do business and in good standing in the jurisdiction of its organization and in all jurisdictions in which the failure to so qualify could reasonably be expected to have a
Material Adverse Effect. 
  

 57 

 6.2 Financial Statements. Borrowers have furnished to Agents (a) audited consolidated
financial statements (including a balance sheet) as to U.S. Borrower that fairly present in all material respects, in accordance with GAAP, the consolidated financial condition and the results of operations of U.S. Borrower as at the end of the
fiscal year ended December 31, 2005; (b) unaudited consolidating financial statements (including a balance sheet) as to U.S. Borrower and its Subsidiaries which fairly present in all material respects, in accordance with GAAP, the
consolidating financial condition and the results of operations of U.S. Borrower and its Subsidiaries, on a consolidating basis, as at the end of the fiscal year ended December 31, 2005; and (c) unaudited consolidated and consolidating
financial statements (including a balance sheet) as to U.S. Borrower and its Subsidiaries which fairly present in all material respects, in accordance with GAAP, the consolidated and consolidating financial condition and the results of operations of
U.S. Borrower and its Subsidiaries as at the end of the fiscal quarter ended March 31, 2006. No events, conditions or circumstances have occurred from the date that the financial statements were delivered to Agent through the Effective Date
which would cause said financial statements to be misleading in any material respect. Except for the Loan Documents, there are no material instruments or liabilities which should be reflected in such financial statements provided to Agent which are
not so reflected. 
 6.3 Enforceable Obligations; Authorization. The Loan Documents to which the applicable Obligors are parties are
legal, valid and binding obligations of each applicable Obligor, enforceable in accordance with their respective terms, except as may be limited by bankruptcy, insolvency and other similar laws and judicial decisions affecting creditors’ rights
generally and by general equitable principles. The execution, delivery and performance of the Loan Documents by the respective Obligors (a) have all been duly authorized by all necessary corporate action; (b) are within the corporate power
and authority of each applicable Obligor; (c) do not and will not contravene or violate any Legal Requirement applicable to any applicable Obligor or the Organizational Documents of any applicable Obligor, the contravention or violation of
which could reasonably be expected to have a Material Adverse Effect; (d) do not and will not result in the breach of, or constitute a default under, any material agreement or instrument by which any Obligor or any of its Property may be bound;
and (e) do not and will not result in the creation of any Lien upon any Property of any Obligor, except in favor of Agents as expressly contemplated herein or therein. All necessary permits, registrations and consents for such making and
performance have been obtained. Except as otherwise expressly stated in the Security Documents, the Liens of the Loan Documents will constitute valid and perfected first and prior Liens on the Property described therein, subject to no other Liens
whatsoever except Permitted Liens. 
 6.4 Other Debt. No Obligor is in default in the payment of any other Borrowed Money Indebtedness
or under any agreement, mortgage, deed of trust, security agreement or lease to which it is a party and which default could reasonably be expected to have a Material Adverse Effect. 
 6.5 Litigation. Except as set forth on Schedule 6.5 hereto, there is no material litigation or administrative proceeding, to the knowledge
of any executive officer of any 
  

 58 

 Borrower, pending or threatened against, nor any material outstanding judgment, order or decree against, any Obligor
before or by any Governmental Authority. No Obligor is in default with respect to any judgment, order or decree of any Governmental Authority where such default could reasonably be expected to have a Material Adverse Effect. 
 6.6 Title. Each Obligor has good and defensible title to the Collateral, if any, pledged (or purported to be pledged) by such Obligor pursuant to
the Security Documents, free and clear of all Liens (except Liens permitted under Section 8.2 hereof). 
 6.7 Taxes. Each
Obligor has filed all tax returns required to have been filed by it and paid all taxes shown thereon to be due, except those for which extensions have been obtained and those which are being contested in good faith or where the failure to make
required filings or pay required taxes could not reasonably be expected to have a Material Adverse Effect. 
 6.8 Regulations U and X.
None of the proceeds of any Loan or proceeds from the acceptance and purchase of Bankers’ Acceptances will be used for the purpose of purchasing or carrying directly or indirectly any margin stock or for any other purpose that would constitute
this transaction a “purpose credit” within the meaning of Regulations U and X of the Board of Governors of the Federal Reserve System, as any of them may be amended from time to time. 
 6.9 Subsidiaries. As of the Effective Date, U.S. Borrower has no Subsidiaries other than as set forth on Schedule 6.9 hereto. The
percentage of the issued and outstanding Equity Interests in each applicable Subsidiary which is owned by U.S. Borrower or one or more of its Subsidiaries is set forth on Schedule 6.9 hereto. 
 6.10 No Untrue or Misleading Statements. No document, instrument or other writing furnished to the Lenders by or on behalf of any Obligor in
connection with the transactions contemplated in any Loan Document contains any untrue statement of material fact or omits to state any such fact necessary to make the representations, warranties and other statements contained herein or in such
other document, instrument or writing not misleading in any material respect. 
 6.11 ERISA. With respect to each Plan, each Borrower
and each member of the Controlled Group have fulfilled their obligations, including obligations under the minimum funding standards of ERISA and the Code and are in compliance in all material respects with the provisions of ERISA and the Code. No
event has occurred which could result in a liability of any Borrower or any member of the Controlled Group to the PBGC or a Plan (other than to make contributions in the ordinary course) that could reasonably be expected to have a Material Adverse
Effect. There have not been any nor are there now existing any events or conditions that would cause the Lien provided under Section 4068 of ERISA to attach to any Property of any Borrower or any member of the Controlled Group. Except as
described on Schedule 6.11 hereto, the aggregate Unfunded Liabilities in respect of all Plans as of the date hereof do not exceed $5,000,000. No “prohibited transaction” has occurred with respect to any Plan. 
 6.12 Investment Company Act. No Obligor is an investment company within the meaning of the Investment Company Act of 1940, as amended, or,
directly or indirectly, controlled by or acting on behalf of any Person which is an investment company, within the meaning of said Act.

Borrower and its Subsidiaries, on a consolidated basis, Canadian Borrower and its Subsidiaries, on a consolidated basis, or U.K. Borrower and its Subsidiaries, on a consolidated basis, is “insolvent,” as such term is used and defined in
(i) the Bankruptcy Code and (ii) the fraudulent conveyance statutes of the State of Texas or of any jurisdiction in which any of the Collateral may be located or unable to pay its debts within the meaning of Section 123 of the
Insolvency Act 1986 (England and Wales). 
 6.14 Fiscal Year. The fiscal year of each Obligor ends on December 31. 
 6.15 Compliance. Each Obligor is in compliance with all Legal Requirements applicable to it, except to the extent that the failure to comply
therewith could not reasonably be expected to have a Material Adverse Effect. 
 6.16 Environmental Matters. Each Obligor has, to the
best knowledge of their respective executive officers, obtained and maintained in effect all Environmental Permits (or the applicable Person has initiated the necessary steps to transfer the Environmental Permits into its name or obtain such
permits), the failure to obtain which could reasonably be expected to have a Material Adverse Effect. Each Obligor and its Properties, business and operations have been and are, to the best knowledge of their respective executive officers, in
compliance with all applicable Requirements of Environmental Law and Environmental Permits the failure to comply with which could reasonably be expected to have a Material Adverse Effect. Each Obligor and its Properties, business and operations are
not subject to any (A) Environmental Claims or (B), to the best knowledge of their respective executive officers (after making reasonable inquiry of the personnel and records of their respective Corporations), Environmental Liabilities, in
either case direct or contingent, arising from or based upon any act, omission, event, condition or circumstance occurring or existing on or prior to the date hereof which could reasonably be expected to have a Material Adverse Effect. None of the
officers of any Obligor has received any notice of any violation or alleged violation of any Requirements of Environmental Law or Environmental Permit or any Environmental Claim in connection with its Properties, liabilities, condition (financial or
otherwise), business or operations which could reasonably be expected to have a Material Adverse Effect. None of U.S. Borrower, Canadian Borrower or U.K. Borrower knows of any event or condition with respect to currently enacted Requirements of
Environmental Laws presently scheduled to become effective in the future with respect to any of the Properties of any Obligor which could reasonably be expected to have a Material Adverse Effect, for which the applicable Obligor has not made good
faith provisions in its business plan and projections of financial performance. 
 6.17 Collateral Covered. As of the Effective Date,
the Collateral covered by the Security Documents constitutes substantially all real Property (other than the Excluded Real Property) and substantially all material personal Property owned by U.S. Borrower and its Subsidiaries (other than Excluded
Subsidiaries and Foreign Subsidiaries which are not Subsidiaries of Canadian Borrower or U.K. Borrower) and all of the issued and outstanding Equity Interests in all of the Subsidiaries of U.S. Borrower (other than Excluded Subsidiaries and

  

 60 

 Foreign Subsidiaries which are not Subsidiaries of Canadian Borrower or U.K. Borrower) owned by U.S. Borrower or any of
its Subsidiaries (with the Collateral being allocated among Canadian Obligations, U.K. Obligations and U.S. Obligations as herein provided). 
 6.18 Property of Excluded Subsidiaries and Certain Foreign Subsidiaries. The aggregate value (based on the greater of book or market value) of the Property owned by Excluded Subsidiaries or by Foreign Subsidiaries of U.S. Borrower
(other than Canadian Borrower, U.K. Borrower or their Subsidiaries) as of the Effective Date is no greater than $10,000,000. 
 7. Affirmative
Covenants. 
 U.S. Borrower, Canadian Borrower and U.K. Borrower each covenants and agrees with Agents and the Lenders that prior to the
payment of all Obligations and the termination of all U.S. Commitments, Canadian Commitments and U.K. Commitments it will do or cause to be done, and cause each other Obligor (unless limited by the language of the applicable provision to less than
all of the Obligors) to do or cause to be done, each and all of the following: 
 7.1 Taxes, Existence, Regulations, Property, Etc. At
all times, except where failure or noncompliance could not reasonably be expected to have a Material Adverse Effect: (a) pay when due all taxes and governmental charges of every kind upon it or against its income, profits or Property, unless
and only to the extent that the same shall be contested diligently in good faith and adequate reserves in accordance with GAAP have been established therefor; (b) do all things necessary to preserve its existence, qualifications, rights and
franchises; (c) comply with all applicable Legal Requirements (including without limitation Requirements of Environmental Law) in respect of the conduct of its business and the ownership of its Property; and (d) cause its Property to be

or special, time or demand, provisional or final (but excluding the funds held in accounts clearly designated as escrow or trust accounts held by U.S. Borrower, Canadian Borrower, U.K. Borrower or any other Obligor for the benefit of Persons which
are not Affiliates of any Obligor), whether or not such setoff results in any loss of interest or other penalty, and including without limitation all certificates of deposit, at any time held, and any other funds or Property at any time held, and
other Borrowed Money Indebtedness at any time owing by such Lender to or for the credit or the account of U.S. Borrower, Canadian Borrower, U.K. Borrower or any other Obligor against any and all of the Obligations irrespective of whether or not such
Lender or any Agent will have made any demand under this Agreement, the Notes or any other Loan Document. Should the right of any Lender to realize funds in any manner set forth hereinabove be challenged and any application of such funds be
reversed, whether by court order or otherwise, the Lenders shall make restitution or refund to U.S. Borrower, Canadian Borrower or U.K. Borrower or the applicable other Obligor, as the case may be, pro rata in accordance with their U.S. Commitments,
Canadian Commitments or U.K. Commitments, as the case may be. Each Lender agrees to promptly notify U.S. Borrower, Canadian Borrower, U.K. Borrower and Agents after any such setoff and application, provided that the failure to give such notice will
not affect the validity of such setoff and application. The rights of Agents and the Lenders under this Section are in addition to other rights and remedies (including without limitation other rights of setoff) which Agents or the Lenders may have.
This Section is subject to the terms and provisions of Sections 4.5 and 11.7 hereof. Notwithstanding anything to the contrary contained herein or in any of the other Loan Documents, any amounts realized under this Section which
constitute an asset of any Foreign Subsidiary shall only be applied to the payment of Canadian Obligations or U.K. Obligations. 
 9.3
Collateral Account. U.S. Borrower hereby agrees, in addition to the provisions of Section 9.1 hereof, that upon the occurrence and during the continuance of any Event of Default, it shall, if requested by any Agent or by the
Majority Lenders (through any Agent), pay to U.S. Agent an amount in immediately available funds equal to the then aggregate amount available for drawings under all outstanding U.S. Letters of Credit, which funds shall be held by U.S. 
  

 73 

 Agent as Cover. Canadian Borrower hereby agrees, in addition to the provisions of Section 9.1 hereof, that
upon the occurrence and during the continuance of any Event of Default, it shall, if requested by any Agent or by the Majority Lenders (through any Agent), pay to Canadian Agent an amount in immediately available funds equal to the sum of the then
aggregate amount available for drawings under all outstanding Canadian Letters of Credit plus the unpaid principal balance of all outstanding Bankers’ Acceptances, which funds shall be held by Canadian Agent as Cover. U.K. Borrower hereby
agrees, in addition to the provisions of Section 9.1 hereof, that upon the occurrence and during the continuance of any Event of Default, it shall, if requested by any Agent or by the Majority Lenders (through any Agent), pay to U.K.
Agent an amount in immediately available funds equal to the then aggregate amount available for drawings under all outstanding U.K. Letters of Credit, which funds shall be held by U.K. Agent as Cover. 
 9.4 Preservation of Security for Letter of Credit Liabilities. In the event that, following (i) the occurrence of an Event of Default and the
exercise of any rights available to any Agent or any Lender under the Loan Documents, and (ii) payment in full of the principal amount then outstanding of and the accrued interest on the Loans and Reimbursement Obligations and fees and all
other amounts payable hereunder and under the Loan Documents and all other amounts secured by the Security Documents, any Letters of Credit or Bankers’ Acceptances shall remain outstanding and undrawn upon, the applicable Agent shall be
entitled to hold (and each Borrower and each other Obligor hereby grants and conveys to Agent a security interest in and to) all cash or other Property (“Proceeds of Remedies”) realized or arising out of the exercise of any rights
available under the Loan Documents, at law or in equity, including, without limitation, the proceeds of any foreclosure, as collateral for the payment of any amounts due or to become due under or in respect of such Letters of Credit and/or such
Bankers’ Acceptances. Such Proceeds of Remedies shall be held for the ratable benefit of the U.S. Lenders, the Canadian Lenders or U.K. Lenders, as the case may be. The rights, titles, benefits, privileges, duties and obligations of the
applicable Agent with respect thereto shall be governed by the terms and provisions of this Agreement and, to the extent not inconsistent with this Agreement, the applicable Security Documents. The applicable Agent may, but shall have no obligation
to, invest any such Proceeds of Remedies in such manner as such Agent, in the exercise of its sole discretion, deems appropriate. Such Proceeds of Remedies shall be applied to Reimbursement Obligations arising in respect of any such Letters of
Credit, the payment of any Lender’s obligations under any such Letter of Credit and/or the Obligations relating to any such Bankers’ Acceptance when such Letter of Credit is drawn upon or such Bankers’ Acceptance matures, as the case
may be. Nothing in this Section shall cause or permit an increase in the maximum amount of the Obligations permitted to be outstanding from time to time under this Agreement. Notwithstanding anything to the contrary contained herein or in any of the
other Loan Documents, any amounts realized under this Section which constitute an asset of any Foreign Subsidiary shall only be applied to the payment of Canadian Obligations or U.K. Obligations. 
 9.5 Remedies Cumulative. No remedy, right or power conferred upon any Agent or any Lender is intended to be exclusive of any other remedy, right
or power given hereunder or now or hereafter existing at law, in equity, or otherwise, and all such remedies, rights and powers shall be cumulative. 
  

 74 

 10. Agents. 
 10.1 Appointment, Powers and Immunities. Each U.S. Lender hereby irrevocably appoints and authorizes U.S. Agent to act as its agent hereunder, under the U.S. Letters of Credit and under the other Loan Documents with such powers as
are specifically delegated to U.S. Agent by the terms hereof and thereof, together with such other powers as are reasonably incidental thereto. Each Canadian Lender hereby irrevocably appoints and authorizes Canadian Agent to act as its agent
hereunder, under the Canadian Letters of Credit and under the other Loan Documents with such powers as are specifically delegated to Canadian Agent by the terms hereof and thereof, together with such other powers as are reasonably incidental
thereto. Each U.K. Lender hereby irrevocably appoints and authorizes U.K. Agent to act as its agent hereunder, under the U.K. Letters of Credit and under the other Loan Documents with such powers as are specifically delegated to U.K. Agent by the
terms hereof and thereof, together with such other powers as are reasonably incidental thereto. Any Loan Documents executed in favor of any Agent shall be held by such Agent for the ratable benefit of the applicable Lenders. None of the Agents
(“Agents” as used in this Section 10 shall include reference to their Affiliates and their own and their Affiliates’ respective officers, shareholders, directors, employees and agents) (a) shall have any duties or
responsibilities except those expressly set forth in this Agreement, the Letters of Credit, and the other Loan Documents, and shall not by reason of this Agreement or any other Loan Document be a trustee or fiduciary for any Lender; (b) shall
be responsible to any Lender for any recitals, statements, representations or warranties contained in this Agreement, the Letters of Credit or any other Loan Document, or in any certificate or other document referred to or provided for in, or
received by any of them under, this Agreement, the Letters of Credit or any other Loan Document, or for the value, validity, effectiveness, genuineness, enforceability, execution, filing, registration, collectibility, recording, perfection,
existence or sufficiency of this Agreement, the Letters of Credit, or any other Loan Document or any other document referred to or provided for herein or therein or any Property covered thereby or for any failure by any Obligor or any other Person
to perform any of its obligations hereunder or thereunder, or shall have any duty to inquire into or pass upon any of the foregoing matters; (c) shall be required to initiate or conduct any litigation or collection proceedings hereunder or
under the Letters of Credit or any other Loan Document except to the extent requested and adequately indemnified by the Majority Lenders; (d) shall be responsible for any mistake of law or fact or any action taken or omitted to be taken by it
hereunder or under the Letters or Credit or any other Loan Document or any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith, including, without limitation, pursuant to its own
negligence, except for its own gross negligence or willful misconduct; (e) shall be bound by or obliged to recognize any agreement among or between any Borrower and any Lender to which such Agent is not a party, regardless of whether such Agent
has knowledge of the existence of any such agreement or the terms and provisions thereof; (f) shall be charged with notice or knowledge of any fact or information not herein set out or provided to such Agent in accordance with the terms of this
Agreement or any other Loan Document; (g) shall be responsible for any delay, error, omission or default of any mail, telegraph, cable or wireless agency or operator; and (h) shall be responsible for the acts or edicts of any Governmental
Authority. Any Agent may employ agents and attorneys-in-fact and none of the Agents shall be responsible for the negligence or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. Without in any way limiting any of
the foregoing, each Lender acknowledges that none of the Agents (nor any Issuer) shall have greater responsibility in the operation of the Letters of 
  

 75 

 Credit than is specified in the Uniform Customs and Practice for Documentary Credits (1993 Revision, International
Chamber of Commerce Publication No. 500). In any foreclosure proceeding concerning any Collateral, each holder of an Obligation if bidding for its own account or for its own account and the accounts of other Lenders is prohibited from including
in the amount of its bid an amount to be applied as a credit against the Obligations held by it or the Obligations held by the other Lenders; instead, such holder must bid in cash only. However, in any such foreclosure proceeding, (i) U.S.
Agent may (but shall not be obligated to) submit a bid for all U.S. Lenders (including itself) in the form of a credit against the U.S. Obligations, and U.S. Agent or its designee may (but shall not be obligated to) accept title to such collateral
for and on behalf of all U.S. Lenders, (ii) Canadian Agent may (but shall not be obligated to) submit a bid for all Canadian Lenders (including itself) in the form of a credit against the Canadian Obligations, and Canadian Agent or its designee
may (but shall not be obligated to) accept title to such collateral for and on behalf of all Canadian Lenders and (iii) U.K. Agent may (but shall not be obligated to) submit a bid for all U.K. Lenders (including itself) in the form of a credit
against the U.K. Obligations, and U.K. Agent or its designee may (but shall not be obligated to) accept title to such collateral for and on behalf of all U.K. Lenders. 
 10.2 Reliance. Each Agent shall be entitled to rely upon any certification, notice or other communication (including any thereof by telephone, telegram or cable) believed by it to be genuine and correct and to
have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel (which may be counsel for any Borrower), independent accountants and other experts selected by such Agent. None of the Agents
shall be required in any way to determine the identity or authority of any Person delivering or executing the same. As to any matters not expressly provided for by this Agreement, the Letters of Credit, or any other Loan Document, each Agent shall
in all cases be fully protected in acting, or in refraining from acting, hereunder and thereunder in accordance with instructions of the Majority Lenders, and any action taken or failure to act by U.S. Agent pursuant thereto shall be binding on all
of the U.S. Lenders, any action taken or failure to act by Canadian Agent pursuant thereto shall be binding on all of the Canadian Lenders and any action taken or failure to act by U.K. Agent pursuant thereto shall be binding on all of the U.K.
Lenders. Pursuant to written instructions of the Majority Lenders, the Agents shall have the authority to execute releases of the Security Documents on behalf of the Lenders without the joinder of any Lender. If any order, writ, judgment or decree
shall be made or entered by any court affecting the rights, duties and obligations of any Agent under this Agreement or any other Loan Document, then and in any of such events such Agent is authorized, in its sole discretion, to rely upon and comply
with such order, writ, judgment or decree which it is advised by legal counsel of its own choosing is binding upon it under the terms of this Agreement, the relevant Loan Document or otherwise; and if such Agent complies with any such order, writ,
judgment or decree, then it shall not be liable to any Lender or to any other Person by reason of such compliance even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated. 
 10.3 Defaults. None of the Agents shall be deemed to have knowledge of the occurrence of a Default (other than the non-payment of principal of or
interest on Loans or Reimbursement Obligations) unless such Agent has received notice from a Lender or a Borrower specifying such Default and stating that such notice is a “Notice of Default.” In the event that any Agent receives such a
Notice of Default, such Agent shall give prompt notice thereof to the 
  

 76 

 Lenders (and shall give each Lender prompt notice of each such non-payment). Each Agent shall (subject to
Section 10.7 hereof) take such action with respect to such Notice of Default as shall be directed by the Majority Lenders and within its rights under the Loan Documents and at law or in equity, provided that, unless and until an Agent
shall have received such directions, such Agent may (but shall not be obligated to) take such action, or refrain from taking such action, permitted hereby with respect to such Notice of Default as it shall deem advisable in the best interests of the
Lenders and within its rights under the Loan Documents, at law or in equity. 
 10.4 Material Written Notices. In the event that any
Agent receives any written notice of a material nature from any Borrower or any Obligor under the Loan Documents, such Agent shall promptly inform each of the Lenders thereof. 
 10.5 Rights as a Lender. With respect to their U.S. Commitments, Canadian Commitments or U.K. Commitments, as the case may be, and the
Obligations, each of Wells Fargo, HSBC Canada and HSBC U.K., in its capacity as a Lender hereunder, shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting in its agency capacity,
and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include each Agent in its individual capacity. Each Agent may (without having to account therefor to any Lender) accept deposits from, lend money
to and generally engage in any kind of banking, trust, letter of credit, agency or other business with any Borrower (and any of their Affiliates) as if it were not acting as an Agent, and each Agent may accept fees and other consideration from any
Borrower (in addition to the fees heretofore agreed to between any Borrower and any Agent) for services in connection with this Agreement or otherwise without having to account for the same to the Lenders. 
 10.6 Indemnification. The Canadian Lenders, the U.S. Lenders and U.K. Lenders, respectively, agree to indemnify each of (x) Canadian Agent
and the Issuers of the Canadian Letters of Credit; (y) U.S. Agent and the Issuers of the U.S. Letters of Credit, and (z) U.K. Agent and the Issuers of the U.K. Letters of Credit, respectively (to the extent not reimbursed under
Section 2.2(c), Section 11.3 or Section 11.4 hereof, but without limiting the obligations of any Borrower under said Sections 2.2(c), 11.3 and 11.4), ratably in accordance with the sum of the
applicable Lenders’ respective Canadian Commitments, U.S. Commitments and U.K. Commitments, for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature
whatsoever, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY INDEMNIFIED PARTIES, which may be imposed on, incurred by or asserted against the applicable Agent or Issuer in any way relating to or arising out of this
Agreement, the Letters of Credit or any other Loan Document or any other documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby (including, without limitation, the costs and expenses which any
Borrower is obligated to pay under Sections 2.2(c), 11.3 and 11.4 hereof, interest, penalties, attorneys’ fees and amounts paid in settlement, but excluding, unless a Default has occurred and is continuing, normal
administrative costs and expenses incident to (a) in the case of an Agent, the performance of its agency duties hereunder, and (b) in the case of an Issuer, the performance of its duties as Issuer hereunder) or the enforcement of any of
the terms hereof or thereof or of any such other documents; provided that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the party to be indemnified. The obligations of
the Lenders under this Section 10.6 shall survive the termination of this Agreement and the repayment of the Obligations. 
  

 77 

 10.7 Non-Reliance on Agents and Other Lenders. Each Lender agrees that it has received current
financial information with respect to each Borrower and each other Obligor and that it has, independently and without reliance on any Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own
credit analysis of each Borrower and each other Obligor and decision to enter into this Agreement and that it will, independently and without reliance upon any 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 analysis and decisions in taking or not taking action under this Agreement or any of the other Loan Documents. None of the Agents shall be required to keep itself informed as to the performance or
observance by any Obligor of this Agreement, the Letters of Credit or any of the other Loan Documents or any other document referred to or provided for herein or therein or to inspect the properties or books of any Obligor. Except for notices,
reports and other documents and information expressly required to be furnished to the Lenders by an Agent hereunder, under the Letters of Credit or the other Loan Documents, none of the Agents shall have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial condition or business of any Obligor (or any of their Affiliates) which may come into the possession of any Agent. 
 10.8 Failure to Act. Except for action expressly required of an Agent hereunder, under the Letters of Credit or under the other Loan Documents,
each Agent shall in all cases be fully justified in failing or refusing to act hereunder and thereunder unless it shall receive further assurances to its satisfaction by the Lenders of their indemnification obligations under Section 10.6
hereof against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. 
 10.9 Resignation or Removal of Agent. Subject to the appointment and acceptance of a successor U.S. Agent, Canadian Agent or U.K. Agent, as the case may be, as provided below, U.S. Agent, Canadian Agent and U.K. Agent, respectively,
may resign at any time by giving notice thereof to the U.S. Lenders, the Canadian Lenders and U.K. Lenders, respectively, and to U.S. Borrower, Canadian Borrower and U.K. Borrower, respectively. Any Agent may be removed at any time with or without
cause by the Majority Lenders; provided, that such Agent shall continue as U.S. Agent, Canadian Agent or U.K. Agent, as the case may be, until such time as any successor shall have accepted appointment hereunder as U.S. Agent, Canadian Agent or U.K.
Agent, as the case may be. Upon any such resignation or removal, (i) the Majority Lenders without the consent of any Borrower shall have the right to appoint a successor U.S. Agent, Canadian Agent or U.K. Agent, as the case may be, so long as
such successor U.S. Agent, Canadian Agent or U.K. Agent, as the case may be, is also a Lender at the time of such appointment and (ii) the Majority Lenders shall have the right to appoint a successor U.S. Agent, Canadian Agent or U.K. Agent, as
the case may be, that is not a Lender at the time of such appointment so long as Borrowers consent to such appointment (which consent shall not be unreasonably withheld). If no successor U.S. Agent, Canadian Agent or U.K. Agent, as the case may be,
shall have been so appointed by the Majority Lenders and accepted such appointment within 30 days after the retiring U.S. Agent’s, Canadian Agent’s or U.K. Agent’s, as the case may be, giving of notice of resignation or the Majority
Lenders’ removal of the retiring U.S. 
  

 78 

 Agent, Canadian Agent or U.K. Agent, as the case may be, then the retiring Agent may, on behalf of the applicable
Lenders, appoint a successor U.S. Agent, Canadian Agent or U.K. Agent, as the case may be, without the necessity of any consent on the part of any Borrower or any Lender. Any successor U.S. Agent shall be a bank which has an office in the United
States and a combined capital and surplus of at least $250,000,000, any successor Canadian Agent shall be a bank which has an office in Canada and a combined capital and surplus of at least C$250,000,000 and any successor U.K. Agent shall be a bank
which has an office in the United Kingdom and a combined capital and surplus of at least £100,000,000. Upon the acceptance of any appointment as U.S. Agent, Canadian Agent or U.K. Agent, as the case may be, hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent and the retiring Agent shall be discharged from its duties and obligations hereunder and under any other Loan
Documents. Such successor Agent shall promptly specify by notice to Borrowers its Principal Office referred to in Section 3.1 and Section 4 hereof. After any retiring Agent’s resignation or removal hereunder as an Agent,
the provisions of this Section 10 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent. 
 10.10 No Partnership. Neither the execution and delivery of this Agreement nor any of the other Loan Documents nor any interest the Lenders,
Agents or any of them may now or hereafter have in all or any part of the Obligations shall create or be construed as creating a partnership, joint venture or other joint enterprise between the Lenders or among the Lenders and any Agent. The
relationship between the Lenders, on the one hand, and any Agent, on the other, is and shall be that of principals and agent only, and nothing in this Agreement or any of the other Loan Documents shall be construed to constitute any Agent as trustee
or other fiduciary for any Lender or to impose on any Agent any duty, responsibility or obligation other than those expressly provided for herein and therein. 
 10.11 Authority of Agent. Each Lender acknowledges that the rights and responsibilities of each Agent under this Agreement and the Loan Documents with respect to any action taken by such Agent or the exercise
or non-exercise by any Agent of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement and/or the other Loan Documents shall, as between such Agent and the Lenders, be governed
by this Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between such Agent and the Obligors, such Agent shall be conclusively presumed to be acting as agent for the applicable Lenders
with full and valid authority so to act or refrain from acting; and each Obligor shall not be under any obligation, or entitlement, to make any inquiry respecting such authority. 
 10.12 Syndications Agent. Bank of America, N.A., in its capacity as Syndications Agent, shall have no rights, powers, duties, obligations or
liabilities under this Agreement or any of the other Loan Documents, but to the extent that for any reason any Person makes a claim against Bank of America, N.A. in its capacity as Syndications Agent and not as a Lender the indemnification
provisions in Sections 10.6 and 11.4 shall apply in connection with such claim as if Bank of America, N.A. was an Agent under this Agreement. 
  

 79 

 11. Miscellaneous. 
 11.1 Waiver. No waiver of any Default or Event of Default shall be a waiver of any other Default or Event of Default. No failure on the part of any Agent or any Lender to exercise and no delay in exercising,
and no course of dealing with respect to, any right, power or privilege under any Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege thereunder preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law or in equity. 
 11.2 Notices. All notices and other communications provided for herein (including, without limitation, any modifications of, or waivers or
consents under, this Agreement) shall be given or made by telegraph, telecopy (confirmed by mail), cable or other writing and telecopied, telegraphed, cabled, mailed or delivered to the intended recipient at the “Address for Notices”

Lenders, Issuers or Agents under this Agreement or any other Loan Document, including, without limitation, fees and expenses incurred in connection with such Lender’s, Issuer’s or Agent’s participation as a member of a creditor’s

 11.4 Indemnification. Borrowers, jointly and severally, shall indemnify each Agent,
each Lender, each Issuer and each Affiliate thereof and their respective directors, officers, employees and agents from, and hold each of them harmless against, any and all losses, liabilities, claims or damages to which any of them may become
subject, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY INDEMNIFIED PARTIES, insofar as such losses, liabilities, claims or damages arise out of or result from any (i) actual or proposed use by any Borrower of
the proceeds of any extension of credit (whether a Loan, a Bankers’ Acceptance or a Letter of Credit) by any Lender or Issuer hereunder; (ii) breach by any Obligor of this Agreement or any other Loan Document; (iii) violation by any
Obligor of any Legal Requirement; or (iv) investigation, litigation or other proceeding relating to any of the foregoing, and Borrowers, jointly and severally, shall reimburse each Agent, each Lender, each Issuer and each Affiliate thereof and
their respective directors, officers, employees and agents, upon demand for any reasonable and customary expenses (including reasonable and customary legal fees) incurred in connection with any such investigation or proceeding; provided, however,
that none of the Borrowers shall have any obligations pursuant to this Section with respect to any losses, liabilities, claims, damages or expenses incurred by the Person seeking indemnification by reason of the gross negligence or willful
misconduct of that Person or with respect to any disputes between or among any of Agents, Lenders and Issuers. Nothing in this Section is intended to limit the obligations of any Borrower under any other provision of this Agreement. Each Agent,
Lender and Issuer, respectively, shall indemnify Borrowers and hold Borrowers harmless from and against the gross negligence or willful misconduct of such Agent, Lender or Issuer, as the case may be. Nothing in this Section shall render Canadian
Borrower or U.K. Borrower liable in respect of the U.S. Obligations. In the case of any indemnification hereunder, the applicable Agent or the respective Lender or Issuer, as appropriate, shall give written notice to the applicable Borrower of any
such claim or demand being made against an indemnified person and the applicable Borrower shall 
  

 81 

 have the non-exclusive right to join in the defense against any such claim or demand, provided that if such Borrower
provides a defense, the indemnified person shall bear its own cost of defense unless there is a conflict of interests between such Borrower and such indemnified person. No indemnified person may settle any claim to be indemnified without the consent
of the applicable Borrower, such consent not to be unreasonably withheld or delayed. 
 11.5 Amendments, Etc. No amendment or
modification of this Agreement, the Notes or any other Loan Document shall in any event be effective against any Borrower or any other Obligor party thereto unless the same shall be agreed or consented to in writing by such Person. No amendment,
modification or waiver of any provision of this Agreement, the Notes or any other Loan Document, nor any consent to any departure by any Obligor therefrom, shall in any event be effective against the Lenders unless the same shall be agreed or
consented to in writing by the Majority Lenders, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, that no amendment, modification, waiver or consent shall,
unless in writing and signed by each Lender and Issuer affected thereby, do any of the following: (a) increase any U.S. Commitments, Canadian Commitments or U.K. Commitments of any of the Lenders (or reinstate any termination or reduction of
the U.S. Commitments, Canadian Commitments or U.K. Commitments), or subject any of the Lenders to any additional obligations; (b) reduce the principal of, or interest on, any Loan, Reimbursement Obligation, fee or other amount due hereunder;
(c) postpone or extend the Revolving Loan Maturity Date, the Termination Date, the Availability Period or any scheduled date fixed for any payment of principal of, or interest on, any Loan, Reimbursement Obligation, fee or other sum to be paid
hereunder or waive any Event of Default described in Section 9.1(a) hereof; (d) change the percentage of any of the U.S. Commitments, Canadian Commitments or U.K. Commitments, as the case may be, or of the aggregate unpaid principal
amount of Obligations, or the percentage of Lenders, which shall be required for the Lenders or any of them to take any action under this Agreement; (e) change any provision contained in Sections 2.2, 7.9, 11.3 or
11.4 hereof or this Section 11.5; (f) except to the extent expressly authorized under the Loan Documents, release any Person from liability under a Guaranty or release all or substantially all of the security for the
Obligations or release Collateral (exclusive of Collateral with respect to which any Agent is obligated to provide a release pursuant to this Agreement or any of the other Loan Documents or by law) in any one (1) calendar year ascribed an
aggregate value on the most recent financial statements of the applicable Borrower delivered to Agents in excess of $2,500,000; or (h) modify the provisions of Sections 4.1(b) or 4.2 hereof regarding pro rata application of
amounts after an Event of Default shall have occurred and be continuing. Notwithstanding anything in this Section 11.5 to the contrary, no amendment, modification, waiver or consent shall be made with respect to Section 10
without the consent of U.S. Agent to the extent it affects U.S. Agent, as U.S. Agent or Canadian Agent to the extent it affects Canadian Agent, as Canadian Agent or U.K. Agent to the extent it affects U.K. Agent, as U.K. Agent. 
 11.6 Successors and Assigns. 
 (a)
This Agreement shall be binding upon and inure to the benefit of Borrowers, Agents and the Lenders and their respective successors and assigns; provided, however, that, except as permitted by Section 8.4 hereof, no Borrower
may assign or transfer any of its rights or obligations hereunder without the prior written consent of all of the Lenders, and any such 
  

 82 

 assignment or transfer without such consent shall be null and void. Each Lender may sell participations to any Person in
all or part of any Loan or Bankers’ Acceptance, or all or part of its Notes, U.S. Commitments, Canadian Commitments or U.K. Commitments, as the case may be, or interests in Letters of Credit or Bankers’ Acceptances, in which event, without
limiting the foregoing, the provisions of the Loan Documents shall inure to the benefit of each purchaser of a participation; provided, however, the pro rata treatment of payments, as described in Section 4.2
hereof and rights to compensation under Section 3.3 hereof, shall be determined as if such Lender had not sold such participation. No Lender that sells one or more participations to any Person shall be relieved by virtue of such
participation from any of its obligations to Borrowers under this Agreement. In the event any Lender shall sell any participation, such Lender shall retain the sole right and responsibility to enforce the obligations of Borrowers hereunder,
including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement other than amendments, modifications or waivers with respect to (i) any fees payable hereunder to the Lenders,
(ii) the amount of principal or the rate of interest payable on, or the dates fixed for the scheduled repayment of principal of, any of the Obligations and (iii) the release of the Liens on all or substantially all of the Collateral.

 (b) Each U.S. Lender may assign to one or more U.S. Lenders or any other Person all or a portion of its interests, rights and obligations
under this Agreement; provided, however, that (i) the aggregate amount of the U.S. Commitments of the assigning U.S. Lender subject to each such assignment shall in no event be less than $3,000,000 and (ii) other than in the
case of an assignment to another U.S. Lender (that is, at the time of the assignment, a party hereto) or to a Lender Affiliate of such U.S. Lender or to a Federal Reserve Bank, Agents and the Issuers of the then-outstanding U.S. Letters of Credit
and, so long as no Event of Default shall have occurred and be continuing, U.S. Borrower must each give its prior written consent, which consents shall not be unreasonably withheld. Each Canadian Lender may assign to one or more Canadian Lenders or
any other Person all or a portion of its interests, rights and obligations under this Agreement; provided, however, that (i) the aggregate amount of the Canadian Commitments of the assigning Canadian Lender subject to each such
assignment shall in no event be less than $3,000,000 and (ii) other than in the case of an assignment to another Canadian Lender (that is, at the time of the assignment, a party hereto) or to a Lender Affiliate of such Canadian Lender, Agents
and the Issuers of the then-outstanding Canadian Letters of Credit and, so long as no Event of Default shall have occurred and be continuing, Canadian Borrower must each give its prior written consent, which consents shall not be unreasonably
withheld. Each U.K. Lender may assign to one or more U.K. Lenders or any other Person all or a portion of its interests, rights and obligations under this Agreement; provided, however, that (x) the aggregate amount of the U.K.
Commitments of the assigning U.K. Lender subject to each such assignment shall in no event be less than $3,000,000 and (y) other than in the case of an assignment to another U.K. Lender (that is, at the time of the assignment, a party hereto)
or to a Lender Affiliate of such U.K. Lender, Agents and the Issuers of the then-outstanding U.K. Letters of Credit and, so long as no Event of Default shall have occurred and be continuing, U.K. Borrower must each give its prior written consent,
which consents shall not be unreasonably withheld. After giving effect to any assignment (other than an assignment of all of the commitments and Loans of the assigning Lender), the assigning Lender shall have commitments and Loans aggregating at
least $3,000,000 unless otherwise agreed to by the U.S. Borrower and the U.S. Agent. As a condition precedent to any such assignment, the parties to each such assignment shall execute and deliver to the applicable Agent, for its acceptance an
Assignment and Acceptance in substantially the 
  

 83 

 form of Exhibit E hereto (each an “Assignment and Acceptance”) with blanks appropriately
completed, together with any Note or Notes subject to such assignment and a processing and recording fee of $3,000 paid by the assignee (for which Borrowers will have no liability). Upon such execution, delivery and acceptance, from and after the
effective date specified in each Assignment and Acceptance, (A) the assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and
(B) the Lender thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an
assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto except in respect of provisions of this Agreement which survive payment of the Obligations and termination of the U.S. Commitments,
Canadian Commitments or U.K. Commitments, as the case may be). Notwithstanding anything contained in this Agreement to the contrary, any Lender may at any time assign all or any portion of its rights under this Agreement and the other Loan Documents
as collateral to a Federal Reserve Bank; provided that no such assignment shall release such Lender from any of its obligations hereunder. 
 (c) By executing and delivering an Assignment and Acceptance, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than the representation
and warranty that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim, such Lender assignor makes no representation or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or any of the other Loan Documents or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any of the other Loan
Documents or any other instrument or document furnished pursuant thereto; (ii) such Lender assignor makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Borrower or any Obligor or the
performance or observance by any Borrower or any Obligor of any of its obligations under this Agreement or any of the other Loan Documents to which it is a party or any other instrument or document furnished pursuant hereto; (iii) such assignee
confirms that it has received a copy of this Agreement, together with copies of the financial statements most recently delivered under either Section 6.2 or Section 7.2 hereof and such other documents and information as it
has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon any Agent, such Lender assignor or any other Lender and based on
such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents; (v) such assignee appoints and authorizes U.S.
Agent, Canadian Agent or U.K. Agent, as the case may be, to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to such Agent by the terms hereof, together with such
powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all obligations that by the terms of this Agreement and the other Loan Documents are required to be performed by it
as a Lender. 
 (d) The entries in the records of each applicable Agent as to each Assignment and Acceptance delivered to it and the names
and addresses of the Lenders and the U.S. 
  

 84 

 Commitments, Canadian Commitments or U.K. Commitments of, and principal amount of the Obligations owing to, each Lender
from time to time shall be conclusive, in the absence of manifest error, and Obligors, Agents and the Lenders may treat each Person the name of which is recorded in the books and records of the applicable Agent as a Lender hereunder for all purposes
of this Agreement and the other Loan Documents. 
 (e) Upon the applicable Agent’s receipt of an Assignment and Acceptance executed by
an assigning Lender and the assignee thereunder, together with any Note or Notes subject to such assignment and the written consent to such assignment (to the extent consent is required), such Agent shall, if such Assignment and Acceptance has been
completed with blanks appropriately filled, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in its records and (iii) give prompt notice thereof to the applicable Borrower. Within five Business
Days after receipt of notice, the applicable Borrower, at its own expense, shall execute and deliver to the applicable Agent new Notes payable to the order of such assignee in the appropriate amounts and, if the assigning Lender has retained U.S.
Commitments, Canadian Commitments or U.K. Commitments, as the case may be, new Notes to the order of the assigning Lender in the appropriate amounts. Such new Notes shall be dated the effective date of such Assignment and Acceptance and shall
otherwise be in the forms required hereunder. Thereafter, the replaced Notes shall be surrendered to the applicable Agent by the applicable Lender or Lenders, marked renewed and substituted and the originals thereof delivered to the applicable
Borrower (with copies to be retained by the applicable Agent). 
 (f) Any Lender may, in connection with any assignment or participation or
proposed assignment or participation pursuant to this Section 11.6, disclose to the assignee or participant or proposed assignee or participant, any information relating to any Borrower furnished to such Lender by or on behalf of any
Borrower; provided such Person agrees to maintain the confidentiality of such information in accordance with Section 11.19. 
 11.7 Limitation of Interest. U.S. Borrower, U.K. Borrower, U.S. Lenders and U.K. Lenders intend to strictly comply with all applicable usury laws of the United States and Texas (or the usury laws of any jurisdiction, including Canada
and the United Kingdom, whose usury laws are deemed to apply to the Notes or any other Loan Documents despite the intention and desire of the parties to apply the usury laws of the State of Texas). Canadian Borrower and the Canadian Lenders intend
to strictly comply with all applicable usury laws in effect in Canada (or the usury laws of any jurisdiction, including the State of Texas, whose usury laws are deemed to apply to the Notes or any other Loan Documents despite the intention and
desire of the parties to apply the usury laws in effect in Canada). Accordingly, the provisions of this Section 11.7 shall govern and control over every other provision of this Agreement or any other Loan Document which conflicts or is
inconsistent with this Section, even if such provision declares that it controls. As used in this Section, the term “interest” includes the aggregate of all charges, fees, benefits or other compensation which constitute interest under
applicable law, provided that, to the maximum extent permitted by applicable law, (a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money and not
as interest and (b) all interest at any time contracted for, reserved, charged or received shall be amortized, prorated, allocated and spread during the full term of the Obligations. In no event shall Borrowers or any other Person be obligated
to pay, or any Agent, any Issuer or any Lender have any right or privilege to reserve, receive or retain, (a) any interest 
  

 85 

 in excess of the maximum amount of nonusurious interest permitted under applicable laws or (b) total interest in
excess of the amount which such Person could lawfully have contracted for, reserved, received, retained or charged had the interest been calculated for the full term of the Obligations at the Ceiling Rate. None of the terms and provisions contained
in this Agreement or in any other Loan Document (including, without limitation, Section 9.1 hereof) which directly or indirectly relate to interest shall ever be construed without reference to this Section 11.7, or be
construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Ceiling Rate. If the term of any Obligation is shortened by reason of acceleration of maturity as a result of any Default or by
any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason any Agent, any Issuer or any Lender at any time, including but not limited to, the stated maturity, is owed or receives (and/or has
received) interest in excess of interest calculated at the Ceiling Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the
excess, and, if such excess interest has been paid to such Person, it shall be credited pro tanto against the then-outstanding principal balance of the applicable Borrower’s obligations to such Person, effective as of the date or dates when the
event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor.

 11.8 Survival. The obligations of Borrowers under Sections 2.2(c), 2.2(d), 7.9, 11.3 and 11.4
hereof and all other obligations of Borrowers in any other Loan Document (to the extent stated therein), the obligations of each Issuer under the last sentence of Section 2.2(b)(iii) and the obligations of the Lenders under Sections
4.1(d), 10.6, 11.7, 11.13, 11.18 and 11.19 hereof, shall, notwithstanding anything herein to the contrary, survive the repayment of the Loans and Reimbursement Obligations and the termination of the U.S.
Commitments, the Canadian Commitments, the U.K. Commitments and the Letters of Credit. 
 11.9 Captions. Captions and section headings
appearing herein are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement. 
 11.10 Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same agreement and any of the parties hereto may execute this Agreement
by signing any such counterpart. 
 11.11 Governing Law. THIS AGREEMENT AND (EXCEPT AS THEREIN PROVIDED) THE OTHER LOAN DOCUMENTS
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES OF AMERICA FROM TIME TO TIME IN EFFECT; PROVIDED, HOWEVER, THAT, EXCEPT AS MAY BE REQUIRED UNDER APPLICABLE LAWS, THE USURY LAWS OF
THE STATE OF TEXAS OR THE UNITED STATES OF AMERICA SHALL NOT APPLY TO LOANS MADE TO AND BANKERS ACCEPTANCES ACCEPTED IN CANADA BY CANADIAN LENDERS DRAWN BY CANADIAN BORROWER, BUT RATHER THE USURY LAWS IN EFFECT IN CANADA SHALL GOVERN IN SUCH
CONTEXT. 
  

 86 

 11.12 Severability. Whenever possible, each provision of the Loan Documents shall be interpreted
in such manner as to be effective and valid under applicable law. If any provision of any Loan Document shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality and enforceability of the remaining
provisions of such Loan Document shall not be affected or impaired thereby. 
 11.13 Tax Forms; Net Payments. 
 (a) Each U.S. Lender which is organized under the laws of a jurisdiction outside the United States shall, on the day of the initial borrowing from each
such U.S. Lender hereunder and from time to time thereafter if requested by U.S. Borrower or U.S. Agent, provide U.S. Agent and U.S. Borrower with the forms prescribed by the Internal Revenue Service of the United States certifying as to such U.S.
Lender’s status for purposes of determining exemption from United States withholding taxes with respect to all payments to be made to such U.S. Lender hereunder or other documents satisfactory to such U.S. Lender, U.S. Borrower and U.S. Agent
indicating that all payments to be made to such U.S. Lender hereunder are not subject to United States withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty. Unless U.S. Borrower and U.S. Agent shall have received
such forms or such documents indicating that payments to such U.S. Lender hereunder are not subject to United States withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty, U.S. Borrower and U.S. Agent shall be
entitled to withhold taxes from such payments at the applicable statutory rate. 
 (b) Each Canadian Lender is not a non-resident of Canada
for purposes of the Income Tax Act (Canada). 
 (c) Each U.K. Lender is a Qualifying Lender. In this Section 11.13(c),
“Qualifying Lender” means (a) a Lender which is within the charge to U.K. corporation tax in respect of, and beneficially entitled to, a payment of interest on a loan made by a person that was a bank for the purposes of section 349 of
the Income and Corporation Taxes Act 1988 (as currently defined in section 840A of the Income and Corporation Taxes Act) at the time the loan was made, or (b) a Lender which is, on the date a payment of interest falls due hereunder, resident
(as defined in the appropriate double taxation agreement) in a country with which the U.K. has a double taxation agreement giving residents of that country exemption from U.K. taxation on interest and does not carry on a business in the U.K. through
a permanent establishment with which the payment is effectively connected. 
 (d) Each U.K. Lender shall (i) promptly after the date
hereof or promptly after the date of an Assignment and Acceptance pursuant to which it became a Lender and (ii) from time to time thereafter upon the obsolescence or expiration of any previously delivered form or certificate (but only so long
as such Lender remains lawfully able to do so) provide the Borrowers and the Agents with any form or certificate that is required by any taxing authority, or other such forms as shall be appropriate to establish, that such Lender is (y) exempt
from Home Jurisdiction Withholding Taxes on payments pursuant to this Agreement or any other Loan Document. Each U.K. Lender represents and warrants that such information is true and complete in all material respects as of the date it is delivered.
Each such Lender shall promptly notify the Borrowers and the Agents if, because of any change in the jurisdiction of organization or the 
  

 87 

 principle office of such Lender, (A) it is required to withdraw or cancel any form or certificate previously
submitted by it or any form or certificate has otherwise become ineffective or inaccurate or (B) payments to it are or will be subject to withholding of any Home Jurisdiction Withholding Tax to a greater or lesser extent than the extent to
which payments to it pursuant to this Agreement, the Notes or any other Loan Document were previously subject. 
 (e) If a Lender shall
receive a refund of any Taxes paid by a Borrower pursuant to this Agreement by reason of the fact that such Taxes were not correctly or legally asserted, such Lender shall within 90 days after receipt of such refund pay to such Borrower the amount
of such refund along with any interest actually received by such Lender thereon, if any; provided, however, that such payments shall be required only to the extent any Lender can determine, in its good faith judgment, that such refunds are
attributable to payments made by or on behalf of such Borrower; and provided, further, that no Lender shall have any obligation under this Agreement to claim or otherwise seek to obtain any such refund, but agrees to use reasonable efforts to assist
a Borrower in doing so. 
 11.14 Interest Act (Canada). Whenever interest is calculated on the basis of a year of 360 or 365 days, for
the purposes of the Interest Act (Canada), the yearly rate of interest which is equivalent to the rate payable hereunder is the rate payable multiplied by the actual number of days in the year and divided by 360 or 365, as the case may be. All
interest will be calculated using the nominal rate method and not the effective rate method and the deemed reinvestment principle shall not apply to such calculations. 
 11.15 Judgment Currency. The obligation of each Borrower to make payments on any Obligation to the Lenders or to any Agent hereunder in any currency (the “first currency”) shall not be discharged or
satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any other currency (the “second currency”) except to the extent to which such tender or recovery shall result in the effective receipt by the
applicable Lender or the applicable Agent of the full amount of the first currency payable, and accordingly the primary obligation of each Borrower shall be enforceable as an alternative or additional cause of action for the purpose of recovery in
the second currency of the amount (if any) by which such effective receipt shall fall short of the full amount of the first currency payable and shall not be affected by a judgment being obtained for any other sum due hereunder. 
 11.16 Conflicts Between This Agreement and the Other Loan Documents. In the event of any conflict between the terms of this Agreement and the
terms of any of the other Loan Documents, the terms of this Agreement shall control. 
 11.17 Limitation on Charges; Substitute Lenders;
Non-Discrimination. Anything in Sections 2.2(d), 3.3(c) or 7.9 notwithstanding: 
 (1) No Borrower
shall be required to pay to any Lender reimbursement or indemnification with regard to any costs or expenses described in such Sections, unless such Lender notifies the applicable Borrower of such costs or expenses within 90 days after the date paid
or incurred; 
  

 88 

 (2) none of the Lenders shall be permitted to pass through to any Borrower charges and
costs under such Sections on a discriminatory basis (i.e., which are not also passed through by such Lender to other customers of such Lender similarly situated where such customer is subject to documents providing for such pass through); and

 (3) if any Lender elects to pass through to any Borrower any material charge or cost under such Sections or elects to
terminate the availability of LIBOR Borrowings for any material period of time, the applicable Borrower may, within 60 days after the date of such event and so long as no Default shall have occurred and be continuing, elect to terminate such Lender
as a party to this Agreement; provided that, concurrently with such termination such Borrower shall (i) if Agents and each of the other Lenders shall consent, pay that Lender all principal, interest and fees and other amounts owed to
such Lender through such date of termination or (ii) have arranged for another financial institution approved by Agents (such approval not to be unreasonably withheld or delayed) as of such date, to become a substitute Lender for all purposes
under this Agreement in the manner provided in Section 11.6; provided further that, prior to substitution for any Lender, the applicable Borrower shall have given written notice to Agents of such intention and the Lenders shall
have the option, but no obligation, for a period of 60 days after receipt of such notice, to increase their U.S. Commitments, Canadian Commitments or U.K. Commitments, as the case may be, in order to replace the affected Lender in lieu of such
substitution. 
 11.18 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).
EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND
(B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
 11.19 Confidentiality. Each of the Agents, Wells Fargo, HSBC Canada, HSBC U.K. and the Lenders agrees to maintain the confidentiality of the
