 Discontinuance Of The Underlier; Alteration Of Method Of Calculation 

If the Underlier Sponsor discontinues publication of the Underlier, and the Underlier Sponsor or another entity publishes a
successor or substitute equity index that the Calculation Agent determines, in its sole discretion, to be comparable to the Underlier (a “Successor Underlier”), then, upon the Calculation Agent’s notification of that
determination to the Trustee and the Company, the Calculation Agent will substitute the Successor Underlier as calculated by the relevant Underlier Sponsor or any other entity and calculate the Final Underlier Level as described above. Upon any
selection by the Calculation Agent of a Successor Underlier, the Company will cause notice to be given to the Holder of this Security. 

In the event that the Underlier Sponsor discontinues publication of the Underlier prior to, and the discontinuance is
continuing on, the Determination Date and the Calculation Agent determines that no Successor Underlier is available at such time, the Calculation Agent will calculate a substitute Closing Level for the Underlier in accordance with the formula for
and method of calculating the Underlier last in effect prior to the discontinuance, but using only those securities that comprised the Underlier immediately prior to that discontinuance. If a Successor Underlier is selected or the Calculation Agent
calculates a level as a substitute for the Underlier, the Successor Underlier or level will be used as a substitute for the Underlier for all purposes, including the purpose of determining whether a Market Disruption Event exists. 

If on the Determination Date the Underlier Sponsor fails to calculate and announce the level of the Underlier, the
Calculation Agent will calculate a substitute Closing Level of the Underlier in accordance with the formula for and method of calculating the Underlier last in effect prior to the failure, but using only those securities that comprised the Underlier
immediately prior to that failure; provided that, if a Market Disruption Event occurs or is continuing on such day, then the provisions set forth below under “Market Disruption Events” shall apply in lieu of the foregoing.

 If at any time the Underlier Sponsor makes a material change in the formula for or the method of calculating the
Underlier, or in any other way materially modifies the Underlier (other than a modification prescribed in that formula or method to maintain the Underlier in the event of changes in constituent stock and capitalization and other routine events),
then, from and after that time, the Calculation Agent will, at the close of business in New York, New York, on each date that the Closing Level of the Underlier is to be calculated, calculate a substitute Closing Level of the Underlier in accordance
with the formula for and method of calculating the Underlier last in effect prior to the change, but using only those securities that comprised the Underlier immediately prior to that change. Accordingly, if the method of calculating the Underlier
is modified so that the level of the Underlier is a fraction or a multiple of what it would have been if it had not been modified, then the Calculation Agent will adjust the Underlier in order to arrive at a level of the Underlier as if it had not
been modified. 

  
 4 

 Market Disruption Events 

A “Market Disruption Event” means any of the following events as determined by the Calculation Agent in its
sole discretion: 
  

	 	(A)	 The occurrence or existence of a material suspension of or limitation imposed on trading by the Relevant Stock
Exchanges or otherwise relating to securities which then comprise 20% or more of the level of the Underlier or any Successor Underlier at any time during the one-hour period that ends at the Close of Trading on that day, whether by reason of
movements in price exceeding limits permitted by those Relevant Stock Exchanges or otherwise. 

  

	 	(B)	 The occurrence or existence of a material suspension of or limitation imposed on trading by any Related
Futures or Options Exchange or otherwise in futures or options contracts relating to the Underlier or any Successor Underlier on any Related Futures or Options Exchange at any time during the one-hour period that ends at the Close of Trading on that
day, whether by reason of movements in price exceeding limits permitted by the Related Futures or Options Exchange or otherwise. 

  

	 	(C)	 The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the
ability of market participants in general to effect transactions in, or obtain market values for, securities that then comprise 20% or more of the level of the Underlier or any Successor Underlier on their Relevant Stock Exchanges at any time during
the one-hour period that ends at the Close of Trading on that day. 

  

	 	(D)	 The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the
ability of market participants in general to effect transactions in, or obtain market values for, futures or options contracts relating to the Underlier or any Successor Underlier on any Related Futures or Options Exchange at any time during the
one-hour period that ends at the Close of Trading on that day. 

  

	 	(E)	 The closure on any Exchange Business Day of the Relevant Stock Exchanges on which securities that then
comprise 20% or more of the level of the Underlier or any Successor Underlier are traded or any Related Futures or Options Exchange prior to its Scheduled Closing Time unless the earlier closing time is announced by the Relevant Stock Exchange or
Related Futures or Options Exchange, as applicable, at least one hour prior to the earlier of (1) the actual closing time for the regular trading session on such Relevant Stock Exchange or Related Futures or Options Exchange, as applicable, and
(2) the submission deadline for orders to be entered into the Relevant Stock Exchange or Related Futures or Options Exchange, as applicable, system for execution at such actual closing time on that day. 

  
 5 

	 	(F)	 The Relevant Stock Exchange for any security underlying the Underlier or Successor Underlier or any Related
Futures or Options Exchange fails to open for trading during its regular trading session. 

 For purposes
of determining whether a Market Disruption Event has occurred: 
  

	 	(1)	 the relevant percentage contribution of a security to the level of the Underlier or any Successor Underlier
will be based on a comparison of (x) the portion of the level of such underlier attributable to that security and (y) the overall level of the Underlier or Successor Underlier, in each case immediately before the occurrence of the Market
Disruption Event; 

  

	 	(2)	 the “Close of Trading” on any Trading Day for the Underlier or any Successor Underlier means
the Scheduled Closing Time of the Relevant Stock Exchanges with respect to the securities underlying the Underlier or Successor Underlier on such Trading Day; provided that, if the actual closing time of the regular trading session of any
such Relevant Stock Exchange is earlier than its Scheduled Closing Time on such Trading Day, then (x) for purposes of clauses (A) and (C) of the definition of “Market Disruption Event” above, with respect to any security
underlying the Underlier or Successor Underlier for which such Relevant Stock Exchange is its Relevant Stock Exchange, the “Close of Trading” means such actual closing time and (y) for purposes of clauses (B) and (D) of the
definition of “Market Disruption Event” above, with respect to any futures or options contract relating to the Underlier or Successor Underlier, the “close of trading” means the latest actual closing time of the regular trading
session of any of the Relevant Stock Exchanges, but in no event later than the Scheduled Closing Time of the Relevant Stock Exchanges; 

  

	 	(3)	 the “Scheduled Closing Time” of any Relevant Stock Exchange or Related Futures or Options
Exchange on any Trading Day for the Underlier or any Successor Underlier means the scheduled weekday closing time of such Relevant Stock Exchange or Related Futures or Options Exchange on such Trading Day, without regard to after hours or any other
trading outside the regular trading session hours; and 

  

	 	(4)	 an “Exchange Business Day” means any Trading Day for the Underlier or any Successor Underlier
on which each Relevant Stock Exchange for the securities underlying the Underlier or any Successor Underlier and each Related Futures or Options Exchange are open for trading during their respective regular trading sessions, notwithstanding any such
Relevant Stock Exchange or Related Futures or Options Exchange closing prior to its Scheduled Closing Time. 

 If a Market
Disruption Event occurs or is continuing on the Determination Date, then the Determination Date will be postponed to the first succeeding Trading Day on which a Market Disruption Event has not occurred and is not continuing; however, if such first
succeeding Trading Day has not occurred as of the eighth Trading Day after the originally scheduled Determination Date, that eighth Trading Day shall be deemed to be the Determination Date. If 

  
 6 

 
the Determination Date has been postponed eight Trading Days after the originally scheduled Determination Date and a Market Disruption Event occurs or is continuing on such eighth Trading Day,
the Calculation Agent will determine the Closing Level of the Underlier on such eighth Trading Day in accordance with the formula for and method of calculating the Closing Level of the Underlier last in effect prior to commencement of the Market
Disruption Event, using the closing price (or, with respect to any relevant security, if a Market Disruption Event has occurred with respect to such security, its good faith estimate of the value of such security at the Scheduled Closing Time of the
Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange) on such date of each security included in the Underlier. As used herein, “closing price”
means, with respect to any security on any date, the Relevant Stock Exchange traded or quoted price of such security as of the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the
regular trading session of such Relevant Stock Exchange. 
 Calculation Agent 

The Calculation Agent will determine the Cash Settlement Amount and the Final Underlier Level. In addition, the Calculation
Agent will (i) determine if adjustments are required to the Closing Level of the Underlier under the circumstances described in this Security, (ii) if publication of the Underlier is discontinued, select a Successor Underlier or, if no
Successor Underlier is available, determine the Closing Level of the Underlier under the circumstances described in this Security, and (iii) determine whether a Market Disruption Event or non-Trading Day has occurred. 

The Company covenants that, so long as this Security is Outstanding, there shall at all times be a Calculation Agent (which
shall be a broker-dealer, bank or other financial institution) with respect to this Security. 

All determinations made by the Calculation Agent with respect to this Security will be at the sole discretion of the
Calculation Agent and, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and the Holder of this Security. 

Tax Considerations 

The Company agrees, and by acceptance of a beneficial ownership interest in this Security each Holder of this Security will be
deemed to have agreed (in the absence of a statutory, regulatory, administrative or judicial ruling to the contrary), for United States federal income tax purposes to characterize this Security as a prepaid derivative contract that is an “open
transaction.” 
 Redemption and Repayment 

This Security is not subject to redemption at the option of the Company or repayment at the option of the Holder hereof prior
to September 20, 2018. This Security is not entitled to any sinking fund. 

  
 7 

 Acceleration 

If an Event of Default, as defined in the Indenture, with respect to this Security shall occur and be continuing, the Cash
Settlement Amount (calculated as set forth in the next sentence) of this Security may be declared due and payable in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted
under the Indenture will be equal to the Cash Settlement Amount hereof calculated as provided herein as though the date of acceleration was the Determination Date. 
  

 

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions
shall for all purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication
hereon has been executed by the Trustee referred to on the reverse hereof by manual signature or its duly authorized agent under the Indenture referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

WELLS FARGO & COMPANY 

MEDIUM-TERM NOTE, SERIES K 

Due Nine Months or More From Date of Issue 

Principal at Risk Securities Linked to the S&P 500® Index 

This Security 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 July 21, 1999, as amended or supplemented from time to time (herein called the “Indenture”), between the Company and
Citibank, N.A., as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), 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 Security is
one of the series of the Securities designated as Medium-Term Notes, Series K, of the Company, which series is limited to an aggregate principal amount or face amount, as applicable, of $25,000,000,000 or the equivalent thereof in one or more
foreign or composite currencies. The amount payable on the Securities of this series may be determined by reference to the performance of one or more equity-, commodity- or currency-based indices, exchange traded funds, securities, commodities,
currencies, statistical measures of economic or financial performance, or a basket comprised of two or more of the foregoing, or any other market measure or may bear interest at a fixed rate or a floating rate. The Securities of this series may
mature at different times, be redeemable at different times or not at all, be repayable at the option of the Holder at different times or not at all and be denominated in different currencies. 

Article Sixteen of the Indenture shall not apply to this Security. 

The Securities are issuable only in registered form without coupons and will be either
(a) book-entry securities represented by one or more Global Securities recorded in the book-entry system maintained by the Depositary or (b) certificated
securities issued to and registered in the names of, the beneficial owners or their nominees. 
 The Company agrees, to the
extent permitted by law, not to voluntarily claim the benefits of any laws concerning usurious rates of interest against a Holder of this Security. 

Modification and Waivers 

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 of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the
Securities at the time Outstanding of all series to be affected, acting together as a class. The Indenture also contains 

  
 10 

 
provisions permitting the Holders of a majority in principal amount of the Securities of all series at the time Outstanding affected by certain provisions of the Indenture, acting together as a
class, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with those provisions of the Indenture. Certain past defaults under the Indenture and their consequences may be waived under the Indenture by the
Holders of a majority in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series. Solely for the purpose of determining whether any consent, waiver, notice or other action
or Act to be taken or given by the Holders of Securities pursuant to the Indenture has been given or taken by the Holders of Outstanding Securities in the requisite aggregate principal amount, the principal amount of this Security will be deemed to
be equal to the amount set forth on the face hereof as the “Face Amount” hereof. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of
any Security 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 Security.

Indenture and subject to the limitations provided therein and to the limitations described below, without charge except for any tax or other governmental charge imposed in connection therewith.

hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or any successor corporation, whether by virtue of
any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

	 	(a)	Conversions of Libor Loans and Bankers’ Acceptances may only be made on the last day of the Interest Period applicable thereto; 

 

	 	(b)	the Borrower may not convert a portion only or the whole of an outstanding Loan unless both the unconverted portion and converted portion of such Loan are equal to or exceed, in the relevant currency of each such
portion, the minimum amounts required for Drawdowns of Loans of the same type as that portion (as set forth in Section 2.5); 

  -
 31
 - 
  

	 	(c)	in respect of Conversions of a Loan denominated in one currency to a Loan denominated in another currency, the Borrower shall at the time of the Conversion repay the Loan or portion thereof being converted in the
currency in which it was denominated, but this shall not constitute a repayment under section 2.14; and 

  

	 	(d)	a Conversion shall not result in an increase in Outstanding Principal; increases in Outstanding Principal may only be effected by Drawdowns. 

 

	2.9	Libor Loan Rollovers; Selection of Libor Interest Periods

required hereunder for Drawdowns of Libor Loans) with respect to the aggregate amount of such Loan, deliver a Rollover Notice to the Agent selecting the next Interest Period applicable to the Libor Loan, which new Interest Period shall commence on
and include the last day of such prior Interest Period. If the Borrower fails to deliver a Rollover Notice to the Agent as provided in this Section, the Borrower shall be deemed to have given a Conversion Notice to the Agent electing to convert the
entire amount of the maturing Libor Loan into a U.S. Base Rate Loan. 
  

	2.10	Rollovers and Conversions not Repayments 

 Any amount converted shall be a Loan of
the type converted to upon such Conversion taking place, and any amount rolled over shall continue to be the same type of Loan under the Credit Facility as before the Rollover, but such Conversion or Rollover (to the extent of the amount converted
or rolled over) shall not of itself constitute a repayment or a fresh utilization of any part of the amount available under the Credit Facility. 
  

	2.11	Agent’s Obligations with Respect to Canadian Prime Rate Loans, U.S. Base Rate Loans and Libor Loans 

Upon receipt of a Drawdown Notice, Rollover Notice or Conversion Notice with respect to a Canadian Prime Rate Loan, U.S. Base Rate Loan or
Libor Loan, the Agent shall forthwith notify the Lenders of the requested type of Loan, the proposed Drawdown Date, Rollover Date or Conversion Date, each Lender’s Rateable Portion of such Loan and, if applicable, the account of the Agent to

Loan, a U.S. Base Rate Loan or a Libor Loan, credit the applicable Agent’s Account with such Lender’s Rateable Portion of each such requested Loan and for same day value on the same date the Agent shall pay to the Borrower the full amount
of the amounts so credited in accordance with any payment instructions set forth in the applicable Drawdown Notice. 

  -
 32
 - 
  

	2.13	Irrevocability 

 A Drawdown Notice, Rollover Notice, Conversion Notice or
Repayment Notice given by the Borrower hereunder shall be irrevocable and, subject to any options the Lenders may have hereunder in regard thereto and the Borrower’s rights hereunder in regard thereto, shall oblige the Borrower to take the
action contemplated on the date specified therein. 
  

	2.14	Optional Repayment of the Credit Facility 

 The Borrower may at any time and from
time to time repay, without penalty, to the Agent for the account of the Lenders the whole or any part of any Loan owing by it together with accrued interest thereon to the date of such repayment provided that: 

 

	 	(a)	the Borrower shall give a Repayment Notice (executed in accordance with the definition of Officer’s Certificate) to the Agent not later than: 

 

	 	(i)	10:00 a.m. (Calgary time) three Banking Days prior to the date of the proposed repayment, for Libor Loans; 

  

	 	(ii)	10:00 a.m. (Calgary time) two Banking Days prior to the date of the proposed repayment, for Banker’s Acceptances; and 

  

	 	(iii)	10:00 a.m. (Calgary time) one Banking Day prior to the date of the proposed repayment, for Canadian Prime Rate Loans and U.S. Base Rate Loans; 

 

	 	(b)	repayments pursuant to this Section may only be made on a Banking Day; 

  

	 	(c)	subject to the following provisions and Section 2.16, each such repayment may only be made on the last day of the applicable Interest Period with regard to a Libor Loan that is being repaid; 

 

	 	(d)	a Bankers’ Acceptance may only be repaid on its maturity unless collateralized in accordance with Section 2.16(2); 

  

	 	(e)	each such repayment shall be in a minimum amount of the lesser of: (i) the minimum amount required pursuant to Section 2.5 for Drawdowns of the type of Loan proposed to be repaid and (ii) the Outstanding
Principal of all Loans outstanding under the Credit Facility immediately prior to such repayment; any repayment in excess of such amount shall be in integral multiples of $1,000,000; and 

 

	 	(f)	the Borrower may not repay a portion only of an outstanding Loan unless the unpaid portion is equal to or exceeds, in the relevant currency, the minimum amount required pursuant to Section 2.5 for Drawdowns of the
type of Loan proposed to be repaid. 

  -
 33
 - 
  

	2.15	Mandatory Repayment of the Credit Facility 

 Subject to Section 10.2 and
Article 7, the Borrower shall repay or pay, as the case may be, to the Agent, on behalf of each of the Lenders, all Loans and other Obligations owing to each Lender on or before the Maturity Date. 

 

	2.16	Additional Repayment Terms 

 (1) If any Libor Loan is repaid on other than the
last day of the applicable Interest Period, the Borrower shall, within three Banking Days after notice is given by the Agent, pay to the Agent for the account of the Lenders all costs, losses, premiums and expenses incurred by the Lenders by reason
of the liquidation or re-deployment of deposits or other funds, or for any other reason whatsoever, resulting in each case from the repayment of such Loan or any part thereof on other than the last day of the
applicable Interest Period. If pursuant to the provisions of this Section or any other provision hereof the Borrower becomes obliged to pay such costs, losses, premiums and expenses, each Lender shall use reasonable efforts to minimize such costs,
losses, premiums and expenses; provided, however, that such Lender shall have no obligation to expend its own funds, suffer any economic hardship or take any action detrimental to its interests in connection therewith. Any Lender, upon becoming
entitled to be paid such costs, losses, premiums and expenses, shall deliver to the Borrower and the Agent a certificate of the Lender certifying as to such amounts and, in the absence of manifest error, such certificate shall be conclusive and
binding for all purposes. 
 (2) With respect to the repayment of unmatured Bankers’ Acceptances pursuant to Section 2.14(d) or
otherwise hereunder, it is agreed that the Borrower shall provide for the funding in full of the unmatured Bankers’ Acceptances to be repaid by paying to and depositing with the Agent cash collateral (the “Cash Collateral”) for
such unmatured Bankers’ Acceptances equal to the face amount payable at maturity thereof; such Cash Collateral deposited by the Borrower shall be invested by the Agent in Approved Securities as may be directed in writing by the Borrower from
time to time (the “Collateral Investments”), provided that the Borrower shall direct said investments so that they mature in amounts sufficient to permit payment of the Obligations for maturing Bankers’ Acceptances on the
maturity dates thereof, with interest thereon to be credited to the Borrower. In the event that the Agent is not provided with instructions from the Borrower to make Collateral Investments as provided herein, the Agent shall hold such Cash
Collateral in an interest bearing cash collateral account (the “Cash Collateral Account”) at rates prevailing at the time of deposit for similar accounts with the Agent. The (a) Cash Collateral, (b) Cash Collateral
Accounts, (c) Collateral Investments, (d) any accounts receivable, claims, instruments or securities evidencing or relating to the foregoing, and (e) any proceeds of any of the foregoing (collectively, the “Outstanding BAs
Collateral”) shall be assigned to the Agent as security for the obligations of the Borrower in relation to such Bankers’ Acceptances and the Security Interest of the Agent thereby created in such Outstanding BAs Collateral shall rank
in priority to all other Security Interests and adverse claims against such Outstanding BAs Collateral. Such Outstanding BAs Collateral shall be applied to satisfy the obligations of the Borrower for such Bankers’ Acceptances as they mature and
the Agent is hereby irrevocably directed by the Borrower to apply any such Outstanding BAs Collateral to such maturing Bankers’ Acceptances. The Outstanding BAs Collateral created herein shall not be released to the Borrower without the consent
of all of the Lenders; however, interest on such deposited amounts shall be for the account of the Borrower and 

  -
 34
 - 
  

 
may be withdrawn by the Borrower so long as no Default or Event of Default is then continuing. If, after maturity of the Bankers’ Acceptances for which such Outstanding BAs Collateral is
held and application by the Agent of the Outstanding BAs Collateral to satisfy the obligations of the Borrower hereunder with respect to the Bankers’ Acceptances being repaid, any interest or other proceeds of the Outstanding BAs Collateral
remains, such interest or other proceeds shall be promptly paid and transferred by the Agent to the Borrower so long as no Default or Event of Default is then continuing. 
  

	2.17	Currency Excess 

 (1) If the Agent shall determine that the aggregate Outstanding
Principal of the outstanding Loans under the Credit Facility exceeds the maximum amount of the Credit Facility (the amount of such excess is herein called the “Currency Excess”), then, upon written request by the Agent (which
request shall detail the applicable Currency Excess), the Borrower shall repay an amount of Canadian Prime Rate Loans or U.S. Base Rate Loans under the Credit Facility within (a) if the Currency Excess exceeds Cdn.$25,000,000, 5 Banking Days,
and (b) in all other cases, 20 Banking Days after receipt of such request, such that, except as otherwise contemplated in Section 2.17(2), the Equivalent Amount in Canadian Dollars of such repayments is, in the aggregate, at least equal to
the Currency Excess. 
 (2) If, in respect of any Currency Excess, the repayments made by the Borrower have not completely removed such
Currency Excess (the remainder thereof being herein called the “Currency Excess Deficiency”), the Borrower shall within the aforementioned 5 or 20 Banking Days, as the case may be, after receipt of the aforementioned request of the
Agent, place an amount equal to the Currency Excess Deficiency on deposit with the Agent in an interest-bearing account with interest at rates prevailing at the time of deposit for the account of the Borrower,
to be assigned to the Agent on behalf of the Lenders by instrument satisfactory to the Agent and to be applied to maturing Bankers’ Acceptances or Libor Loans (converted if necessary at the exchange rate for determining the Equivalent Amount on
the date of such application). The Agent is hereby irrevocably directed by the Borrower to apply any such sums on deposit to maturing Loans, as provided in the preceding sentence. In lieu of providing funds for the Currency Excess Deficiency, as
provided in the preceding provisions of this Section, the Borrower may within the said period of 5 or 20 Banking Days, as the case may be, provide to the Agent an irrevocable standby letter of credit in an amount equal to the Currency Excess
Deficiency and for a term which expires not sooner than 10 Banking Days after the date of maturity or expiry, as the case may be, of the relevant Bankers’ Acceptances or Libor Loans, as the case may be; such letter of credit shall be issued by
a financial institution, and shall be on terms and conditions, acceptable to the Agent in its sole discretion. The Agent is hereby authorized and directed to draw upon such letter of credit and apply the proceeds of the same to Bankers’
Acceptances or Libor Loans as they mature. Upon the Currency Excess being eliminated as aforesaid or by virtue of subsequent changes in the exchange rate for determining the Equivalent Amount, then, provided no Default or Event of Default is then
continuing, such funds on deposit, together with interest thereon, or such letters of credit shall be returned to the Borrower, in the case of funds on deposit, or shall be cancelled or reduced in amount, in the case of letters of credit.

	2.18	Takeover Notification 

 (1) In the event the Borrower wishes to utilize Drawdowns
to, or to provide funds to any Subsidiary to, finance a Hostile Acquisition then the following steps shall be followed: 
  

	 	(a)	at least 5 Banking Days prior to the delivery of any notice to the Agent pursuant to Section 2.7 requesting Drawdowns intended to be utilized for such Hostile Acquisition, the president, chief financial officer,
vice president and treasurer or general counsel of the Borrower shall advise a senior official of each Lender and the Agent (designated by each Lender and the Agent at the particular time for such purpose) of the particulars of such Hostile
Acquisition in sufficient detail to enable each Lender to determine whether it has an actual conflict of interest if Drawdowns from such Lender are utilized by the Borrower for such Hostile Acquisition ; and 

 

	 	(b)	within 3 Banking Days of being so advised: 

  

	 	(i)	if a Lender shall not have notified the Borrower and the Agent that an actual conflict of interest exists (such determination to be made by each Lender in the exercise of its sole discretion having regard to such
considerations as it deems appropriate), such Lender shall be deemed to have no such actual conflict of interest; or 

  

	 	(ii)	if a Lender has notified the Borrower and the Agent within such period of 3 Banking Days that such an actual conflict of interest exists, then upon the Borrower and the Agent being so notified, such Lender shall have no
obligation to provide Drawdowns directly or indirectly to finance such Hostile Acquisition notwithstanding any other provision of this Agreement to the contrary. 

(2) If any notification has been made by a Lender pursuant to Section 2.18(1)(b)(ii) then, except as provided in Section 2.18(3)
below, Rateable Portions of any Loans made to finance the Hostile Acquisition in respect of which such notice was given shall be determined without reference to the Commitment of such Lender; any such notification by a given Lender shall not relieve
any other Lender of any of its obligations hereunder, provided that, for certainty, no Lender shall be obligated by this Section to make or provide Loans in excess of its Commitment. 

(3) If the conflict of interest giving rise to a notification under Section 2.18(1)(b)(ii) ceases to exist (whether by successful
completion of the Hostile Acquisition or otherwise), then the Lender giving such notification shall, on the next Rollover or Conversion of or, in the case of a Canadian Prime Rate Loan or a U.S. Base Rate Loan, the next Interest Payment Date for,
the Loans made to finance the relevant Hostile Acquisition, purchase, and the other Lenders shall on a rateable basis sell and assign to such Lender, portions of such Loans equal in total to the notifying Lender’s Rateable Portion thereof
without regard to Sections 2.18(1) and 2.18(2). 
  

	2.19	Replacement of Lenders 

 The Borrower shall have the right, at its option, to
(a) replace (by causing a Lender to assign its rights and interests under the Credit Facility to additional financial institutions or to 

  -
 36
 - 
  

 
existing Lenders which have agreed to increase their Commitments) or (b) provided that no Default or Event of Default has occurred and is continuing, repay the Obligations outstanding and
cancel the Commitments of (without corresponding repayment to or cancellation of the Commitments of other Lenders) or (c) do any combination thereof with respect to: (i) those Lenders which have not agreed to a consent under, waiver of or
proposed amendment to the provisions of the Documents (each, a “Dissenting Lender”) requested by the Borrower, (ii) those Lenders which have notified the Borrower that they have a conflict of interest in respect of a Hostile
Acquisition pursuant to Section 2.18, (iii) in any calendar year, up to four Lenders which, in the aggregate, do not have Commitments which represent more than 15% of the Commitments of all Lenders, (iv) those Lenders which have
notified the Borrower and the Agent of an entitlement to receive Additional Compensation under Section 11.3, (v) those Lenders which, pursuant to Section 11.5, have declared their obligations under this Agreement in respect of any
Loan to be terminated and (vi) any Defaulting Lender (and such Lender described in clauses (i), (ii), (iii), (iv), (v) or (vi), a “Removed Lender”), and for such purposes the provisions of Section 2.19(b) and 2.19(c)
below shall apply thereto provided that, notwithstanding the foregoing: 
  

	 	(a)	the Borrower shall not be entitled to replace or repay a Dissenting Lender unless, after doing so, the requested consent, waiver or amendment would be approved in accordance with the Documents; 

 

	 	(b)	for certainty, the addition of new financial institutions as Lenders shall require the consent of the Agent, such consents not to be unreasonably withheld; 

 

	 	(c)	 the Borrower may require each Removed Lender to assign all of its rights, benefits and interests under the
Documents, its Commitment and its Rateable Portion of all Loans and other Obligations outstanding under the Credit Facility (collectively, the “Assigned Interests”) to (i) any other existing Lenders which have agreed to
increase their Commitments under the Credit Facility and purchase Assigned Interests, and (ii) to the extent the Assigned Interests are not transferred to other existing Lenders, financial institutions selected by the Borrower and acceptable to
the Agent, acting reasonably. Such assignments shall be effective upon execution of assignment documentation satisfactory to the relevant Removed Lender, the assignee, the Borrower and the Agent (each acting reasonably), upon payment to the relevant
Removed Lender (in immediately available funds) by the relevant assignee of an amount equal to its Rateable Portion of all Obligations being assigned and all accrued but unpaid interest and fees hereunder in respect of those portions of the Loans
and Commitments being assigned, upon payment by the relevant assignee to the Agent (for the Agent’s own account) of the recording fee contemplated in Section 14.6, and upon provision satisfactory to the relevant Removed Lender (acting
reasonably) being made for (i) payment at maturity of outstanding Bankers’ Acceptances accepted by it and (ii) any costs, losses, premiums or expenses incurred by such Removed Lender by reason of the liquidation or re-deployment of
deposits or other funds in respect of Libor Loans outstanding hereunder. Upon such assignment and transfer, the Removed Lender in question shall have no further right, interest, benefit or obligation in respect of the Credit Facility and the
assignee thereof shall succeed to the position of such Lender as if the same was an original party hereto in the place and stead of such Removed Lender; for such purpose, to the 

  -
 37
 - 
  

	 	 
extent that the assignee is not already a party hereto, the assignee shall execute and deliver an Assignment Agreement and such other documentation as may be reasonably required by the Agent and
the Borrower to confirm its agreement to be bound by the provisions hereof and to give effect to the foregoing; and 

  

	 	(d)	to the extent that any Removed Lender has not assigned its rights and interests to another Lender or other financial institution as provided in Section 2.19(c) above, the Borrower may, provided that no Default or
Event of Default has occurred and is continuing but otherwise notwithstanding any other provision hereof, repay the Removed Lender’s Rateable Portion of all Loans outstanding under the Credit Facility, together with all accrued but unpaid
interest and fees thereon with respect to its Commitment, without making corresponding repayment to the other existing Lenders and, upon such repayment and provision satisfactory to the relevant Removed Lender (acting reasonably) being made for
(i) payment at maturity of all outstanding Bankers’ Acceptances accepted by such Removed Lender and (ii) any costs, losses, premiums or expenses incurred by such Removed Lender by reason of a liquidation or re-deployments of deposits
or other funds in respect of Libor Loans outstanding hereunder, the Borrower shall cancel such Removed Lender’s Commitment; upon completion of the foregoing, such Removed Lender shall have no further right, interest, benefit or obligation in
respect of the Credit Facility and the Credit Facility shall be reduced by the amount of such Removed Lender’s cancelled Commitment.

 The Agent shall open and maintain books of account evidencing
all Loans and all other amounts owing by the Borrower to the Lenders hereunder. The Agent shall enter in the foregoing accounts details of all amounts from time to time owing, paid or repaid by the Borrower hereunder. The information entered in the

 ARTICLE 5 -
PAYMENTS OF INTEREST AND FEES 
  

	5.1	Interest on Canadian Prime Rate Loans 

 The Borrower shall pay interest on each
Canadian Prime Rate Loan owing by it during each Interest Period applicable thereto in Canadian Dollars at a rate per annum equal to the 

  -
 39
 - 
  

 
Canadian Prime Rate in effect from time to time during such Interest Period plus the Applicable Pricing Rate. Each determination by the Agent of the Canadian Prime Rate applicable from time to
time during an Interest Period shall, in the absence of manifest error, be prima facie evidence thereof. Such interest shall accrue daily and shall be payable in arrears on each Interest Payment Date for such Loan for the period from and
including the Drawdown Date or the preceding Conversion Date or Interest Payment Date, as the case may be, for such Loan to and including the day preceding such Interest Payment Date and shall be calculated on the principal amount of the Canadian
Prime Rate Loan outstanding during such period and on the basis of the actual number of days elapsed in a year of 365 days. Changes in the Canadian Prime Rate shall cause an immediate adjustment of the interest rate applicable to such Loans
without the necessity of any notice to the Borrower. 
  

	5.2	Interest on U.S. Base Rate Loans 

 The Borrower shall pay interest on each U.S.
Base Rate Loan owing by it during each Interest Period applicable thereto in United States Dollars at a rate per annum equal to the U.S. Base Rate in effect from time to time during such Interest Period plus the Applicable Pricing Rate. Each

and shall be calculated on the principal amount of the U.S. Base Rate Loan outstanding during such period and on the basis of the actual number of days elapsed in a year of 365 days. Changes in the U.S. Base Rate shall cause an immediate
adjustment of the interest rate applicable to such Loans without the necessity of any notice to the Borrower. 
  

	5.3	Interest on Libor Loans 

 The Borrower shall pay interest on each Libor Loan owing
by it during each Interest Period applicable thereto in United States Dollars at a rate per annum, calculated on the basis of a 360-day year, equal to the Libor Rate with respect to such Interest Period plus
the Applicable Pricing Rate. Each determination by the Agent of the Libor Rate applicable to an Interest Period shall, in the absence of manifest error, be prima facie evidence thereof. Such interest shall accrue daily and shall be payable in
arrears on each Interest Payment Date for such Loan for the period from and including the Drawdown Date or the preceding Rollover Date, Conversion Date or Interest Payment Date, as the case may be, for such Loan to and including the day preceding
such Interest Payment Date and shall be calculated on the principal amount of the Libor Loan outstanding during such period and on the basis of the actual number of days elapsed divided by 360. 

 

	5.4	Interest Act (Canada); Conversion of 360 Day Rates 

(1) Whenever a rate of interest hereunder is calculated on the basis of a year (the “deemed year”) which contains fewer days
than the actual number of days in the calendar year of calculation, such rate of interest shall be expressed as a yearly rate for purposes of the Interest Act (Canada) by multiplying such rate of interest by the actual number of days in the
calendar year of calculation and dividing it by the number of days in the deemed year. 

  -
 40
 - 
  

 (2) Whenever a rate of interest or other rate per annum hereunder is expressed or calculated
on the basis of a year of 360 days, such rate of interest or other rate shall be expressed as a rate per annum, calculated on the basis of a 365-day year, by multiplying such rate of interest or other
rate by 365 and dividing it by 360. 
  

	5.5	Nominal Rates; No Deemed Reinvestment 

 The principle of deemed reinvestment of
interest shall not apply to any interest calculation under this Agreement; all interest payments to be made hereunder shall be paid without allowance or deduction for deemed reinvestment or otherwise, before and after maturity, default and judgment.
The rates of interest specified in this Agreement are intended to be nominal rates and not effective rates. Interest calculated hereunder shall be calculated using the nominal rate method and not the effective rate method of calculation. 

 

	5.6	Standby Fees 

 (1) The Borrower shall pay to the Agent for the account of the
Lenders a standby fee in Canadian Dollars in respect of the Credit Facility calculated at a rate per annum equal to the Applicable Pricing Rate on the amount, if any, by which the amount of the Outstanding Principal under the Credit Facility for
each day in the period from the date hereof until 30 days from the date hereof is less than the maximum amount for each such day of the Credit Facility. Fees determined in accordance with this Section shall accrue daily from and after the date
hereof and be payable by the Borrower within 10 Banking Days from the date that is 30 days from the date hereof. 
  

	5.7	Agent’s Fees 

 The Borrower shall pay to the Agent, for its own account, from
time to time, until the Credit Facility has been fully cancelled and all Obligations hereunder have been paid in full, a non-refundable annual agency fee in the amount agreed in writing between the Borrower

	5.8	Interest on Overdue Amounts 

 Notwithstanding any other provision hereof, in the
event that any amount due hereunder (including, without limitation, any interest payment) is not paid when due (whether by acceleration or otherwise), the Borrower shall pay interest on such unpaid amount (including, without limitation, interest on
interest), if and to the fullest extent permitted by applicable law, from the date that such amount is due until the date that such amount is paid in full (but excluding the date of such payment if the payment is received for value at the required
place of payment on the date of such payment), and such interest shall accrue daily, be calculated and compounded monthly and be payable on demand, after as well as before maturity, default and judgment, at a rate per annum that is equal to
(a) in respect of amounts due in Canadian Dollars, the rate of interest then payable on Canadian Prime Rate Loans plus 2.0% per annum or (b) in respect of amounts due in United States Dollars, the rate of interest then payable on U.S.
Base Rate Loans plus 2.0% per annum. 

  -
 41
 - 
  

	5.9	Waiver 

 To the extent permitted by applicable law, the covenant of the Borrower
to pay interest at the rates provided herein shall not merge in any judgment relating to any obligation of the Borrower to the Lenders or the Agent and any provision of the Interest Act (Canada) or Judgment Interest Act (Alberta) which
restricts any rate of interest set forth herein shall be inapplicable to this Agreement and is hereby waived by the Borrower. 
  

	5.10	Maximum Rate Permitted by Law 

 No interest or fee to be paid hereunder shall be
paid at a rate exceeding the maximum rate permitted by applicable law. In the event that such interest or fee exceeds such maximum rate, such interest or fees shall be reduced or refunded, as the case may be, so as to be payable at the highest rate
recoverable under applicable law. 
 ARTICLE 6 - BANKERS’ ACCEPTANCES 

 

	6.1	Bankers’ Acceptances 

 The Borrower may give the Agent notice that
Bankers’ Acceptances will be required under the Credit Facility pursuant to a Drawdown, Rollover or Conversion. 
  

	6.2	Fees 

 Upon the acceptance by a Lender of a Bankers’ Acceptance, the Borrower
shall pay to the Agent for the account of such Lender an acceptance fee in Canadian Dollars equal to the Applicable Pricing Rate calculated on the principal amount at maturity of such Bankers’ Acceptance and for the period of time from and
including the date of acceptance to but excluding the maturity date of such Bankers’ Acceptance and calculated on the basis of the number of days elapsed in a year of 365 days. 

 

	6.3	Form and Execution of Bankers’ Acceptances 

 The following provisions shall
apply to each Bankers’ Acceptance hereunder: 
  

	 	(a)	the face amount at maturity of each draft drawn by the Borrower to be accepted as a Bankers’ Acceptance shall be a minimum amount of Cdn.$100,000 and integral multiples of Cdn.$1,000 for amounts in excess of such
minimum amount;; 

  

	 	(b)	the term to maturity of each draft drawn by the Borrower to be accepted as a Bankers’ Acceptance shall, subject to market availability as determined by all of the Lenders, be 1, 2, 3 or 6 months (or such other
longer or shorter term as agreed by all Lenders), as selected by the Borrower in the relevant Drawdown, Rollover or Conversion Notice, and each Bankers’ Acceptance shall be payable and mature on the last day of the Interest Period selected by
the Borrower for such Bankers’ Acceptance (which, for certainty, pursuant to the definition of “Interest Period” shall be on or prior to the Maturity Date); 

  -
 42
 - 
  

	 	(c)	each draft drawn by the Borrower and presented for acceptance by a Lender shall be drawn on the standard form of such Lender in effect at the time; provided, however, that the Agent may require the Lenders to use a
generic form of Bankers’ Acceptance, in a form satisfactory to each Lender, acting reasonably, provided by the Agent for such purpose in place of the Lenders’ own forms; 

 

	 	(d)	subject to Section 6.3(e) below, Bankers’ Acceptances shall be signed by duly authorized officers of the Borrower or, in the alternative, the signatures of such officers may be mechanically reproduced in
facsimile thereon and Bankers’ Acceptances bearing such facsimile signatures shall be binding on the Borrower as if they had been manually executed and delivered by such officers on behalf of the Borrower; notwithstanding that any person whose
manual or facsimile signature appears on any Bankers’ Acceptance may no longer be an authorized signatory for the 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 Borrower; and 

  

	 	(e)	in lieu of signing Bankers’ Acceptances in accordance with Section 6.3(d) above, the Borrower may provide a Power of Attorney to a Lender; for so long as a Power of Attorney is in force with respect to a given
Lender, such Lender shall execute and deliver Bankers’ Acceptances on behalf of the Borrower in accordance with the provisions thereof and, for certainty, all references herein to drafts drawn by the Borrower, Bankers’ Acceptances executed
by the Borrower or similar expressions shall be deemed to include Bankers’ Acceptances executed in accordance with a Power of Attorney, unless the context otherwise requires. 

 

	6.4	Power of Attorney; Provision of Bankers’ Acceptances to Lenders 

 (1) Unless
revoked with respect to a given Lender in accordance herewith, the Borrower hereby appoints each Lender, acting by any authorized signatory of the Lender in question, the attorney of the Borrower: 

 

	 	(a)	to sign for and on behalf and in the name of the Borrower as drawer, drafts in such Lender’s standard form which are depository bills as defined in the Depository Bills and Notes Act (Canada) (the
“DBNA”), payable to a “clearing house” (as defined in the DBNA) including CDS Clearing and Depository Services Inc., or its nominee, CDS & Co. (the “clearing house”); 

 

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

  

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

  

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

  -
 43
 - 
  

 provided that such acts in each case are to be undertaken by the Lender in question strictly in accordance
with instructions given to such Lender by the Borrower as provided in this Section. For certainty, signatures of any authorized signatory of a 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 Lender. 

Instructions from the Borrower to a Lender relating to the execution, completion, endorsement, deposit and/or delivery by that Lender on
behalf of the Borrower of Bankers’ Acceptances which the Borrower wishes to submit to the Lender for acceptance by the Lender shall be communicated by the Borrower in writing to the Agent by delivery to the Agent of Drawdown Notices, Conversion
Notices and Rollover Notices, as the case may be, in accordance with this Agreement which, in turn, shall be communicated by the Agent, on behalf of the Borrower, to the Lender. 

The communication in writing by the Borrower, or on behalf of the Borrower by the Agent, to a Lender of the instructions set out in the
Drawdown Notices, Conversion Notices and Rollover Notices referred to above shall constitute (a) the authorization and instruction of the Borrower to such Lender to sign for and on behalf and in the name of the 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 Borrower to such 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 Borrower acknowledges that a Lender shall not be obligated to accept any such Bankers’ Acceptances
except in accordance with the provisions of this Agreement. 
 A Lender shall be and it is hereby authorized to act on behalf of the
Borrower upon and in compliance with instructions communicated to that Lender as provided herein if the Lender reasonably believes such instructions to be genuine. If a Lender accepts Bankers’ Acceptances pursuant to any such instructions, that
Lender shall confirm particulars of such instructions and advise the Agent that it has complied therewith by notice in writing addressed to the Agent and served personally or sent by telecopier in accordance with the provisions hereof. A
Lender’s actions in compliance with such instructions, confirmed and advised to the Agent by such notice, shall be conclusively deemed to have been in accordance with the instructions of the Borrower. 

This power of attorney may be revoked by the Borrower with respect to any particular Lender at any time upon not less than 5 Banking
Days’ prior written notice served upon the Lender in question and the Agent, provided that no such revocation shall reduce, limit or otherwise affect the obligations of the 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. 
 (2)
Unless the Borrower has provided Powers of Attorney to the Lenders, to facilitate Drawdowns, Rollovers or Conversions of Bankers’ Acceptances, the Borrower shall, upon execution of this Agreement and thereafter from time to time as required by
all Lenders, provide to the Agent for delivery to each Lender drafts drawn in blank by the Borrower (pre-endorsed and otherwise in fully negotiable form, if applicable) in quantities sufficient for each Lender
to fulfil its 

  -
 44
 - 
  

 
obligations hereunder. Any such pre-signed drafts which are delivered by the Borrower to the Agent or a Lender shall be held in safekeeping by the Agent or
such Lender, as the case may be, with the same degree of care as if they were the Agent’s or such Lender’s property, and shall only be dealt with by the Lenders and the Agent in accordance herewith. No Lender shall be responsible or liable
for its failure to make its share of any Drawdown, Rollover or Conversion of Bankers’ Acceptances required hereunder if the cause of such failure is, in whole or in part, due to the failure of the Borrower to provide such pre-signed drafts to the Agent (for delivery to such Lender) on a timely basis. 
 (3) By 10:00 a.m.
(Calgary time) on the applicable Drawdown Date, Conversion Date or Rollover Date, the Borrower shall (a) either deliver to each Lender in Toronto, or, if previously delivered, be deemed to have authorized each Lender to complete and accept, or
(b) where the Borrower has provided a Power of Attorney to the Lender, be deemed to have authorized each such Lender to sign on behalf of the Borrower, complete and accept, drafts drawn by the Borrower on such Lender in a principal amount at
maturity equal to such Lender’s share of the Bankers’ Acceptances specified by the Borrower in the relevant Drawdown Notice, Conversion Notice or Rollover Notice, as the case may be, as notified to the Lenders by the Agent. 

 

	6.5	Mechanics of Issuance 

 (1) Upon receipt by the Agent of a Drawdown Notice,
Conversion Notice or Rollover Notice from the Borrower requesting the issuance of Bankers’ Acceptances, the Agent shall promptly notify the Lenders thereof and advise each Lender of the aggregate face amount of Bankers’ Acceptances to be
accepted by such Lender, the date of issue and the Interest Period for such Loan; the apportionment among the Lenders of the face amounts of Bankers’ Acceptances to be accepted by each Lender shall be determined by the Agent by reference and in
proportion to the respective Commitment of each Lender, provided that, when such apportionment cannot be evenly made, the Agent shall round allocations amongst such Lenders consistent with the Agent’s normal money market practices. 

(2) On each such Drawdown Date, Rollover Date or Conversion Date involving the issuance of Bankers’ Acceptances: 

 

	 	(a)	before 9:00 a.m. (Calgary time) on such date, the Agent shall determine the CDOR Rate and shall obtain quotations from each Schedule II/III Reference Lender of the Discount Rate then applicable to bankers’
acceptances accepted by such Schedule II/III Reference Lender in respect of an issue of bankers’ acceptances in a comparable amount and with comparable maturity to the Bankers’ Acceptances proposed to be issued on such date;

  

	 	(b)	on or about 9:00 a.m. (Calgary time) on such date, the Agent shall determine the BA Discount Rate applicable to each Lender and shall advise each Lender of the BA Discount Rate applicable to it; 

 

	 	(c)	 each Lender shall complete and accept, in accordance with the Drawdown Notice, Conversion Notice or Rollover
Notice delivered by the Borrower and advised by the Agent in connection with such issue, its share of the Bankers’ Acceptances to be 

  -
 45
 - 
  

	 	 
issued on such date and shall purchase such Bankers’ Acceptances for its own account at a purchase price which reflects the BA Discount Rate applicable to such issue; and

  

	 	(d)	in the case of a Drawdown, each Lender shall, for same day value on the Drawdown Date, remit the Discount Proceeds or advance the BA Equivalent Advance, as the case may be, payable by such Lender (net of the acceptance
fee payable to such Lender pursuant to Section 6.2) to the Agent for the account of the Borrower; the Agent shall make such funds available to the Borrower for same day value on such date. 

(3) Each 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 for its own account. 
  

	6.6	Rollover, Conversion or Payment on Maturity 

 In anticipation of the maturity of
Bankers’ Acceptances, the Borrower shall, subject to and in accordance with the requirements hereof, do one or a combination of the following with respect to the aggregate face amount at maturity of all such Bankers’ Acceptances: 

 

	 	(a)	(i) deliver to the Agent a Rollover Notice that the Borrower intends to draw and present for acceptance on the maturity date new Bankers’ Acceptances in an aggregate face amount up to the aggregate amount of
the maturing Bankers’ Acceptances and (ii) on the maturity date pay to the Agent for the account of the Lenders an additional amount equal to the difference between the aggregate face amount of the maturing Bankers’ Acceptances and
the Discount Proceeds of such new Bankers’ Acceptances; 

  

	 	(b)	(i) deliver to the Agent a Conversion Notice requesting a Conversion of the maturing Bankers’ Acceptances to another type of Loan under the Credit Facility and (ii) on the maturity date pay to the Agent
for the account of the Lenders an amount equal to the difference, if any, between the aggregate face amount of the maturing Bankers’ Acceptances and the amount of the Loans into which Conversion is requested; or 

 

	 	(c)	on the maturity date of the maturing Bankers’ Acceptances, pay to the Agent for the account of the Lenders an amount equal to the aggregate face amount of such Bankers’ Acceptances. 

If the Borrower fails to so notify the Agent or make such payments on maturity, the Agent shall effect a Conversion into a Canadian Prime Rate Loan of the
entire amount of such maturing Bankers’ Acceptances as if a Conversion Notice had been given by the Borrower to the Agent to that effect. 
  

	6.7	Restriction on Rollovers and Conversions 

 Subject to the other provisions hereof,
Conversions and Rollovers of Bankers’ Acceptances may only occur on the maturity date thereof. 

  -
 46
 - 
  

	6.8	Rollovers 

 In order to satisfy the continuing liability of the Borrower to a
Lender for the face amount of maturing Bankers’ Acceptances accepted by such Lender, the Lender shall receive and retain for its own account the Discount Proceeds of new Bankers’ Acceptances issued on a Rollover, and the Borrower shall on
the maturity date of the Bankers’ Acceptances being rolled over pay to the Agent for the account of the Lenders an amount equal to the difference between the face amount of the maturing Bankers’ Acceptances and the Discount Proceeds from
the new Bankers’ Acceptances, together with the acceptance fees to which the Lenders are entitled pursuant to Section 6.2. 
  

	6.9	Conversion into Bankers’ Acceptances 

 In respect of Conversions into
Bankers’ Acceptances, in order to satisfy the continuing liability of the Borrower to the Lenders for the amount of the converted Loan, each Lender shall receive and retain for its own account the Discount Proceeds of the Bankers’
Acceptances issued upon such Conversion, and the Borrower shall on the Conversion Date pay to the Agent for the account of the Lenders an amount equal to the difference between the principal amount of the converted Loan and the aggregate Discount
Proceeds from the Bankers’ Acceptances issued on such Conversion, together with the acceptance fees to which the Lenders are entitled pursuant to Section 6.2. 
  

	6.10	Conversion from Bankers’ Acceptances 

 In order to satisfy the continuing
liability of the Borrower to the Lenders for an amount equal to the aggregate face amount of the maturing Bankers’ Acceptances converted to another type of Loan, the Agent shall record the obligation of the Borrower to the Lenders as a Loan of
the type into which such continuing liability has been converted. 
  

	6.11	BA Equivalent Advances 

 Notwithstanding the foregoing provisions of this Article,
a Non-Acceptance Lender shall, in lieu of accepting Bankers’ Acceptances, make a BA Equivalent Advance. The amount of each BA Equivalent Advance shall be equal to the Discount Proceeds which would be
realized from a hypothetical sale of those Bankers’ Acceptances which, but for this Section, such Lender would otherwise be required to accept as part of such a Drawdown, Conversion or Rollover of Bankers’ Acceptances. To determine the
amount of such Discount Proceeds, the hypothetical sale shall be deemed to take place at the BA Discount Rate for such Loan. Any BA Equivalent Advance shall be made on the relevant Drawdown Date, Rollover Date or Conversion Date as the case may be
and shall remain outstanding for the term of the relevant Bankers’ Acceptances. Concurrent with the making of a BA Equivalent Advance, a Non-Acceptance Lender shall be entitled to deduct therefrom an
amount equal to the acceptance fee which, but for this Section, such Lender would otherwise be entitled to receive as part of such Loan. Subject to Section 6.6, upon the maturity date for such Bankers’ Acceptances, the Borrower shall pay
to each Non-Acceptance Lender an amount equal to the face amount at maturity of the Bankers’ Acceptances which, but for this Section, such Lender would otherwise be required to accept as part of such a
Drawdown, Conversion or Rollover of Bankers’ Acceptances as repayment of the amount of its BA Equivalent Advance plus payment of the interest accrued and payable thereon to such maturity date. 

  -
 47
 - 
  

 All references herein to “Loans” and “Bankers’ Acceptances” shall,
unless otherwise expressly provided herein or unless the context otherwise requires, be deemed to include BA Equivalent Advances made by a Non-Acceptance Lender as part of a Drawdown, Conversion or Rollover of
Bankers’ Acceptances. 
  

	6.12	Termination of Bankers’ Acceptances 

 If at any time a Lender ceases to
accept bankers’ acceptances in the ordinary course of its business, such Lender shall be deemed to be a Non-Acceptance Lender and shall make BA Equivalent Advances in lieu of accepting Bankers’
Acceptances under this Agreement. 
 ARTICLE 7 - PLACE AND APPLICATION OF PAYMENTS 

 

	7.1	Place of Payment of Principal, Interest and Fees; Payments to Agent 

 All payments
of principal, interest, fees and other amounts to be made by the Borrower to the Agent and the Lenders pursuant to this Agreement shall be made to the Agent (for, as applicable, the account of the Lenders or its own account) in the currency in which
the Loan is outstanding for value on the day such amount is due, and if such day is not a Banking Day on the Banking Day next following, by deposit or transfer thereof to the applicable Agent’s Account or at such other place as the Borrower and
the Agent may from time to time agree. Notwithstanding anything to the contrary expressed or implied in this Agreement, the receipt by the Agent in accordance with this Agreement of any payment made by the Borrower for the account of any of the
Lenders shall, insofar as the Borrower’s obligations to the relevant Lenders are concerned, be deemed also to be receipt by such Lenders and the Borrower shall have no liability in respect of any failure or delay on the part of the Agent in
disbursing and/or accounting to the relevant Lenders in regard thereto. 
  

	7.2	Designated Accounts of the Lenders 

 All payments of principal, interest, fees or
other amounts to be made by the Agent to the Lenders pursuant to this Agreement shall be made for value on the day required hereunder, provided the Agent receives funds from the Borrower for value on such day, and if such funds are not so received
from the Borrower or if such day is not a Banking Day, on the Banking Day next following, by deposit or transfer thereof at the time specified herein to the account of each Lender designated by such Lender to the Agent for such purpose or to such
other place or account as each Lender may from time to time notify the Agent. 
  

	7.3	Funds 

 Each amount advanced, disbursed or paid hereunder shall be advanced,
disbursed or paid, as the case may be, in such form of funds as may from time to time be customarily used in Calgary, Alberta, Toronto, Ontario and New York, New York in the settlement of banking transactions similar to the banking transactions
required to give effect to the provisions of this Agreement on the day such advance, disbursement or payment is to be made (for certainty, each such amount advanced, disbursed or paid hereunder shall be advanced, disbursed or paid, as the case may
be, in immediately available funds to the extent possible in the relevant jurisdiction). 

  -
 48
 - 
  

	7.4	Application of Payments 

 Except as otherwise agreed in writing by all of the
Lenders, if any Event of Default shall occur and be continuing, all payments made by the Borrower to the Agent and the Lenders shall be applied in the following order: 
  

	 	(a)	to amounts due hereunder as fees other than acceptance fees for Bankers’ Acceptances; 

  

	 	(b)	to amounts due hereunder as costs and expenses; 

  

	 	(c)	to amounts due hereunder as default interest; 

  

	 	(d)	to amounts due hereunder as interest or acceptance fees for Bankers’ Acceptances; and 

  

	 	(e)	to amounts due hereunder as principal (including reimbursement obligations in respect of Bankers’ Acceptances). 

  

	7.5	Payments Clear of Taxes 

 (1) Except as required by law or as expressly provided
in this Section 7.5, any and all payments by the Borrower to the Agent or the Lenders hereunder shall be made free and clear of, and without deduction or withholding for or on account of, any and all present or future Taxes and all liabilities
with respect thereto imposed on the Agent or the Lenders, excluding Excluded Taxes. In addition, the Borrower agrees to pay any present or future stamp, transfer, registration, excise, issues, documentary or other or similar charges or levies which
arise from any payment made under this Agreement or the Loans or in respect of the execution, delivery or registration or the compliance with this Agreement or the other Documents contemplated hereunder. The Borrower shall indemnify and hold
harmless the Agent and the Lenders for the full amount of all of the foregoing Taxes, charges or levies (other than Excluded Taxes) or other amounts paid or payable by the Agent or the Lenders and any liability (including penalties, interest,
additions to tax and reasonable out of pocket expenses) resulting therefrom or with respect thereto. A certificate of the Agent or such Lender as to the amount of such payment or liability delivered to the Borrower by the Agent or such Lender, as
the case may be, shall be conclusive absent manifest error. 
 (2) If the Borrower shall be required by law to deduct or withhold any amount
from any payment or other amount required to be paid to the Agent or the Lenders hereunder (other than in respect of Excluded Taxes) or if any liability in respect of any such withholding or deduction shall be imposed or shall arise from or in
respect of any sum payable to the Agent or the Lenders hereunder (other than in respect of Excluded Taxes), then the sum payable to the Agent or the Lenders hereunder shall be increased as may be necessary so that after making all required
deductions, withholdings, and additional income tax payments attributable thereto (including deductions, withholdings or income tax payable for additional sums payable under this provision) the Agent or the Lenders, as the case may be, receive an
amount equal to the amount they would have received had no such deductions or withholdings been required to be made or if such additional taxes had not been imposed; in addition, the Borrower shall pay the full amount deducted or withheld for such
liabilities to the relevant taxation authority or other authority in accordance 

  -
 49
 - 
  

 
with applicable law, such payment to be made (if the liability is imposed on the Borrower) for its own account or (if the liability is imposed on the Agent or the Lenders) on behalf of and in the
name of the Agent or the Lenders, as the case may be. If the liability is imposed on the Agent or the Lenders, the Borrower shall deliver to the Agent or the Lenders evidence satisfactory to the Agent or the Lenders, acting reasonably, of the
payment to the relevant taxation authority or other authority of the full amount deducted or withheld. 
 (3) (a) If any Taxes (other
than Excluded Taxes) are imposed on or with respect to any payment on or under this Agreement, in consequence of which the Borrower is required to make any indemnification payment to any Lender under Section 7.5(1) or any additional payment to
any Lender under Section 7.5(2), and if such Lender is entitled to a cash refund or to a credit which is applied against Taxes otherwise payable in a taxation year of such Lender and, in either case, which is both identifiable and quantifiable
by such Lender as being attributable to the imposition of such Taxes (a “Tax Refund”), and such Tax Refund may be obtained without increased liability to such Lender by filing one or more forms, certificates, documents, applications
or returns (collectively, the “Tax Forms”), then such Lender shall notify the Borrower and shall, if requested by the Borrower, file such Tax Forms in a timely fashion (provided such Lender receives such request from the Borrower in
a timely fashion). If such Lender subsequently receives a Tax Refund, and such Lender is able to identify the Tax Refund as being attributable, in whole or in part, to the Tax with respect to which such indemnification payment or additional payment
was made, then such Lender shall promptly reimburse the Borrower such amount as such Lender shall determine, acting reasonably and in good faith, to be the proportion of the Tax Refund, together with any interest received thereon, attributable to
such indemnification payment or additional payment as will leave such Lender, after the reimbursement, in the same position as it would have been if the indemnification payment or additional payment had not been required; provided that, if any Tax
Refund reimbursed by a Lender to the Borrower is subsequently disallowed, the Borrower shall repay such Lender such amount (together with interest and, if such refund resulted from a request by the Borrower, any applicable penalty payable by such
Lender to the relevant taxing authority) promptly after receipt of notice by such Lender of such disallowance. The Borrower agrees to reimburse each such Lender for such Lender’s reasonable out-of-pocket costs and expenses, if any, incurred in
complying with any request by the Borrower hereunder and agrees that all costs incurred by such Lender in respect of this Section 7.5(3)(a) may be deducted from the amount of any reimbursement to the Borrower in respect of any Tax Refund
pursuant to this Section 7.5(3)(a). 
 (b) In the event that the Borrower makes any indemnification payment to a Lender under
Section 7.5(1) or any additional payment to any Lender under Section 7.5(2) and in the event such Lender determines in its good faith judgment that it is not liable for the Taxes for which such indemnification payment or additional payment
was made, such Lender agrees, if requested by the Borrower, to use reasonable efforts to cooperate with the Borrower in contesting the liability for such Taxes; provided that, the Borrower shall reimburse such Lender for any reasonable out-of-pocket
costs and expenses incurred in providing such cooperation and shall indemnify and hold such Lender harmless from and against any liabilities incurred as a result of such Lender providing such cooperation or contesting such liability, and provided
further that no such cooperation shall be required if such contest shall, in such Lender’s good faith judgment, subject it to any liability not covered by such indemnity, and provided further that no Lender shall have any obligation to expend
its own funds, suffer any economic hardship or take any action detrimental to its interests (as 

  -
 50
 - 
  

 
determined by the relevant Lender, acting reasonably) in connection therewith unless it shall have received from the Borrower payment therefor or an indemnity with respect thereto, satisfactory
to it. 
  

	7.6	Set Off 

 (1) In addition to any rights now or hereafter granted under applicable
law and not by way of limitation of any such rights, upon the occurrence of an Event of Default which remains unremedied (whether or not the Loans have been accelerated hereunder), the Agent and each Lender shall have the right (and are hereby
authorized by the Borrower) at any time and from time to time to combine all or any of the Borrower’s accounts with the Agent or such Lender, as the case may be, and to set off and to appropriate and to apply any and all deposits (general or
special, term or demand) including, but not limited to, indebtedness evidenced by certificates of deposit whether matured or unmatured, and any other indebtedness at any time held by the Borrower or owing by such Lender or the Agent, as the case may
be, to or for the credit or account of the Borrower against and towards the satisfaction of any Obligations owing by the Borrower, and may do so notwithstanding that the balances of such accounts and the liabilities are expressed in different
currencies, and the Agent and each Lender are hereby authorized to effect any necessary currency conversions at the noon spot rate of exchange announced by the Bank of Canada on the Banking Day before the day of conversion. 

(2) The Agent or the applicable Lender, as the case may be, shall notify the Borrower of any such
set-off from the Borrower’s accounts within a reasonable period of time thereafter, although the Agent or the Lender, as the case may be, shall not be liable to the Borrower for its failure to so notify.

  

	7.7	Margin Changes; Adjustments for Margin Changes 

 (1) Changes in Applicable Pricing
Rate shall be effective: 
  

	 	(a)	in the case of outstanding Bankers’ Acceptances, upon the earlier of (i) 5 Banking Days after any change in the Debt Rating or when the relevant debt ceases to be rated, and (ii) the next Rollover or
Conversion thereof after such change or cessation in rating, as the case may be; 

  

	 	(b)	in all other cases, immediately upon any change in the relevant debt rating of the Borrower or when the relevant debt of the Borrower ceases to be rated; and 

 

	 	(c)	without the necessity of notice to the Borrower. 

 (2) For any Loans outstanding as of the
effective date of a change in an Applicable Pricing Rate: 
  

	 	(a)	in the case of increases in such rates per annum, the Borrower shall pay to the Agent for the account of the Lenders such additional interest or fees, as the case may be, as may be required to give effect to the
relevant increases in the interest or fees payable on or in respect of such Loans from and as of the effective date of the relevant increase in rates; and 

  -
 51
 - 
  

	 	(b)	in the case of decreases in such rates per annum, the Borrower shall receive a credit against subsequent interest payable on Loans or fees payable pursuant to Section 5.6, or Section 6.2, as the case may be,
to the extent necessary to give effect to the relevant decreases in the interest or fees payable on or in respect of such Loans from and as of the effective date of the relevant decrease in rates. 

(3) The additional payments required by Section 7.7(2)(a) shall be made on the first Banking Day of the calendar month immediately
following the calendar month in which the changes in Applicable Pricing Rate are effective. The adjustments required by Section 7.7(2)(b) shall be accounted for in successive interest and fee payments by the Borrower until the amount of the
credit therein contemplated has been fully applied; provided that, upon satisfaction in full of all Obligations and cancellation of the Credit Facility in accordance herewith, the Lenders shall pay to the Borrower an amount equal to any such credit
which remains outstanding. 
 (4) The Borrower shall give written notice to the Agent and agrees to give notice to the Agent of any change
in the Debt Rating by S&P or DBRS promptly upon becoming actually aware of such change. For certainty, the change in the Applicable Pricing Rate shall, subject to Section 7.7(1)(a), be effective from the date of the change in the Debt
Rating by S&P or DBRS, as the case may be, regardless of the date notice thereof is given by the Borrower to the Agent.

of a Drawdown Notice, Rollover Notice or Conversion Notice to the Agent by the Borrower with regard to any requested Libor Loan: 
  

	 	(a)	 the Agent (acting reasonably) determines that by reason of circumstances affecting the London interbank market,
adequate and fair means do not exist for ascertaining the rate of interest with respect to, or deposits are not available in sufficient amounts 

  -
 65
 - 
  

	 	 
in the ordinary course of business at the rate determined hereunder to fund, a requested Libor Loan during the ensuing Interest Period selected; 

 

	 	(b)	the Agent (acting reasonably) determines that the making or continuing of the requested Libor Loan by the Lenders has been made impracticable by the occurrence of an event which materially adversely affects the London
interbank market generally; or 

  

	 	(c)	the Agent is advised by Lenders holding at least 25% of the Commitments of all Lenders hereunder by written notice (each, a “Lender Libor Suspension Notice”), such notice received by the Agent no later
than 2:00 p.m. (Toronto time) on the third Banking Day prior to the date of the requested Drawdown, Rollover or Conversion, as the case may be, that such Lenders have determined (acting reasonably) that the Libor Rate will not or does not represent
the effective cost to such Lenders of United States Dollar deposits in such market for the relevant Interest Period, 

 then the Agent shall
give notice thereof to the Lenders and the Borrower as soon as possible after such determination or receipt of such Lender Libor Suspension Notice, as the case may be, and the Borrower shall, within one Banking Day after receipt of such notice and
in replacement of the Drawdown Notice, Rollover Notice or Conversion Notice, as the case may be, previously given by the Borrower, give the Agent a Drawdown Notice or a Conversion Notice, as the case may be, which specifies the Drawdown of any other
Loan or the Conversion of the relevant Libor Loan on the last day of the applicable Interest Period into any other Loan which would not be affected by the notice from the Agent pursuant to this Section 11.1. In the event the Borrower fails to
give, if applicable, a valid replacement Conversion Notice with respect to the maturing Libor Loans which were the subject of a Rollover Notice, such maturing Libor Loans shall be converted on the last day of the applicable Interest Period into U.S.
Base Rate Loans as if a Conversion Notice had been given to the Agent by the Borrower pursuant to the provisions hereof. In the event the Borrower fails to give, if applicable, a valid replacement Drawdown Notice with respect to a Drawdown
originally requested by way of a Libor Loan, then the Borrower shall be deemed to have requested a Drawdown by way of a U.S. Base Rate Loan in the amount specified in the original Drawdown Notice and, on the originally requested Drawdown Date, the
Lenders (subject to the other provisions hereof) shall make available the requested amount by way of a U.S. Base Rate Loan. 
  

	11.2	Market Disruption Respecting Bankers’ Acceptances 

 If: 

 

	 	(a)	the Agent (acting reasonably) makes a determination, which determination shall be conclusive and binding upon the Borrower, and notifies the Borrower, that there no longer exists an active market for bankers’
acceptances accepted by the Lenders; or 

  

	 	(b)	 the Agent is advised by Lenders holding at least 25% of the Commitments of all Lenders hereunder by written
notice (each, a “Lender BA Suspension Notice”) that such Lenders have determined (acting reasonably) that the BA Discount Rate will not or does not accurately reflect the cost of funds of such Lenders or the discount rate

  -
 66
 - 
  

	 	 
which would be applicable to a sale of Bankers’ Acceptances accepted by such Lenders in the market; 

then: 
  

	 	(c)	the right of the Borrower to request Bankers’ Acceptances or BA Equivalent Advances from any Lender shall be suspended until the Agent determines that the circumstances causing such suspension no longer exist, and
so notifies the Borrower and the Lenders; 

  

	 	(d)	any outstanding Drawdown Notice requesting a Loan by way of Bankers’ Acceptances or BA Equivalent Advances shall be deemed to be a Drawdown Notice requesting a Loan by way of Canadian Prime Rate Loans in the amount
specified in the original Drawdown Notice; 

  

	 	(e)	any outstanding Conversion Notice requesting a Conversion of a Loan by way of U.S. Base Rate Loans or Libor Loans into a Loan by way of Bankers’ Acceptances or BA Equivalent Advances shall be deemed to be a
Conversion Notice requesting a Conversion of such Loan into a Loan by way of Canadian Prime Rate Loans; and 

  

	 	(f)	any outstanding Rollover Notice requesting a Rollover of a Loan by way of Bankers’ Acceptances or BA Equivalent Advances, shall be deemed to be a Conversion Notice requesting a Conversion of such Loans into a Loan
by way of Canadian Prime Rate Loans. 

 The Agent shall promptly notify the Borrower and the Lenders of any suspension of the Borrower’s
right to request the Bankers’ Acceptances or BA Equivalent Advances and of any termination of any such suspension. A Lender BA Suspension Notice shall be effective upon receipt of the same by the Agent if received prior to 2:00 p.m. (Toronto
time) on a Banking Day and if not, then on the next following Banking Day, except in connection with a Drawdown Notice, Conversion Notice or Rollover Notice previously received by the Agent, in which case the applicable Lender BA Suspension Notice
shall only be effective with respect to such previously received Drawdown Notice, Conversion Notice or Rollover Notice if received by the Agent prior to 2:00 p.m. (Toronto time) two Banking Days prior to the proposed Drawdown Date, Conversion Date
or Rollover Date (as applicable) applicable to such previously received Drawdown Notice, Conversion Notice or Rollover Notice, as applicable. 
  

	11.3	Change in Law 

 (1) If the adoption of any applicable law, regulation, treaty or
official directive (whether or not having the force of law) or any change therein or in the interpretation or application thereof by any court or by any Governmental Authority or any other entity charged with the interpretation or administration
thereof or compliance by a Lender with any request or direction (whether or not having the force of law) of any such authority or entity in each case after the date hereof: 
  

	 	(a)	 subjects such Lender to, or causes the withdrawal or termination of a previously granted exemption with respect
to, any Taxes (other than Excluded Taxes), or changes the basis of taxation of payments due to such Lender, or increases any 

  -
 67
 - 
  

	 	 
existing Taxes (other than Excluded Taxes) on payments of principal, interest or other amounts payable by the Borrower to such Lender under this Agreement; 

 

	 	(b)	imposes, modifies or deems applicable any reserve, liquidity, special deposit, regulatory or similar requirement against assets or liabilities held by, or deposits in or for the account of, or loans by such Lender, or
any acquisition of funds for loans or commitments to fund loans or obligations in respect of undrawn, committed lines of credit or in respect of Bankers’ Acceptances accepted by such Lender; 

 

	 	(c)	imposes on such Lender or requires there to be maintained by such Lender any capital adequacy or additional capital requirements (including, without limitation, a requirement which affects such Lender’s allocation
of capital resources to its obligations) in respect of any Loan or obligation of such Lender hereunder, or any other condition with respect to this Agreement; or 

  

	 	(d)	directly or indirectly affects the cost to such Lender of making available, funding or maintaining any Loan or otherwise imposes on such Lender any other condition or requirement affecting this Agreement or any Loan or
any obligation of such Lender hereunder; 

 and the result of (a), (b), (c) or (d) above, in the sole determination of such Lender
acting in good faith, is: 
  

	 	(e)	to increase the cost to such Lender of performing its obligations hereunder with respect to any Loan; 

  

	 	(f)	to reduce any amount received or receivable by such Lender hereunder or its effective return hereunder or on its capital in respect of any Loan or the Credit Facility; or 

 

	 	(g)	to cause such Lender to make any payment with respect to or to forego any return on or calculated by reference to, any amount received or receivable by such Lender hereunder with respect to any Loan or the Credit
Facility; 

 such Lender shall determine that amount of money which shall compensate the Lender for such increase in cost, payments to be made
or reduction in income or return or interest foregone (herein referred to as “Additional Compensation”). Notwithstanding anything herein to the contrary, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act
and all regulations, requests, rules, guidelines or directives thereunder or issued in connection therewith and (ii) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on
Banking Supervision (or any successor or similar authority) or the United States, Canadian or other regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to be a change in applicable law for the purposes of this
Section 11.3(1), regardless of the date enacted, adopted or issued. Upon a Lender having determined that it is entitled to Additional Compensation in accordance with the provisions of this Section, such Lender shall promptly so notify the
Borrower and the Agent. The relevant Lender shall provide the Borrower and the Agent with a photocopy of the relevant law, rule, guideline, regulation, treaty or official directive (or, if it is impracticable to provide a photocopy, a written
summary of the same) and a certificate of a duly authorized officer of 

  -
 68
 - 
  

 
such Lender setting forth the Additional Compensation and the basis of calculation therefor, which shall be conclusive evidence of such Additional Compensation in the absence of manifest error.
The Borrower shall pay to such Lender within 10 Banking Days of the giving of such notice such Lender’s Additional Compensation. Each of the Lenders shall be entitled to be paid such Additional Compensation from time to time to the extent that
the provisions of this Section are then applicable notwithstanding that any Lender has previously been paid any Additional Compensation. 

(2) Each Lender agrees that it will not claim Additional Compensation from the Borrower under Section 11.3(1): 

 

	 	(a)	if it is not generally claiming similar compensation from its other customers in similar circumstances; 

  

	 	(b)	in respect of any period greater than 90 days prior to the delivery of notice in respect thereof by such Lender, unless the adoption, change or other event or circumstance giving rise to the claim for Additional
Compensation is retroactive or is retroactive in effect; or 

  

	 	(c)	to the extent (but only to the extent) the claim for Additional Compensation would duplicate additional amounts such Lender is already receiving pursuant to Section 7.5 in respect of the same adoption, change or
other event or circumstance giving rise to the claim for Additional Compensation. 

  

	11.4	Prepayment of Portion 

 In addition to the other rights and options of the
Borrower hereunder and notwithstanding any contrary provisions hereof, if a Lender gives the notice provided for in Section 11.3 with respect to any Loan (an “Affected Loan”), the Borrower may, upon 2 Banking Days’ notice
to that effect given to such Lender and the Agent (which notice shall be irrevocable), prepay in full without penalty such Lender’s Rateable Portion of the Affected Loan outstanding together with accrued and unpaid interest on the principal
amount so prepaid up to the date of such prepayment, such Additional Compensation as may be applicable to the date of such payment and all costs, losses and expenses incurred by such Lender by reason of the liquidation or re-deployment of deposits or other funds or for any other reason whatsoever resulting from the repayment of such Affected Loan or any part thereof on other than the last day of the applicable Interest Period, and
upon such payment being made that Lender’s obligations to make such Affected Loans to the Borrower under this Agreement shall terminate. 
  

	11.5	Illegality 

 If a Lender determines, in good faith, that the adoption of any
applicable law, regulation, treaty or official directive (whether or not having the force of law) or any change therein or in the interpretation or application thereof by any court or by any Governmental Authority or any other entity charged with
the interpretation or administration thereof or compliance by a Lender with any request or direction (whether or not having the force of law) of any such authority or entity, now or hereafter makes it unlawful or impossible for any Lender to make,
fund or maintain a Loan under the Credit Facility or to give effect to its obligations in respect of such a Loan, such Lender may, by written notice thereof to the Borrower and to the Agent declare its obligations under this Agreement

  -
 69
 - 
  

 
in respect of such Loan to be terminated whereupon the same shall forthwith terminate, and the Borrower shall, within the time required by such law (or at the end of such longer period as such
Lender at its discretion has agreed), either effect a Conversion of such Loan in accordance with the provisions hereof (if such Conversion would resolve the unlawfulness or impossibility) or prepay the principal of such Loan together with accrued
interest, such Additional Compensation as may be applicable with respect to such Loan to the date of such payment and all costs, losses and expenses incurred by the Lenders by reason of the liquidation or
re-deployment of deposits or other funds or for any other reason whatsoever resulting from the repayment of such Loan or any part thereof on other than the last day of the applicable Interest Period. If any
such change shall only affect a portion of such Lender’s obligations under this Agreement which is, in the opinion of such Lender and the Agent, severable from the remainder of this Agreement so that the remainder of this Agreement may be
continued in full force and effect without otherwise affecting any of the obligations of the Agent, the other Lenders or the Borrower hereunder, such Lender shall only declare its obligations under that portion so terminated. 

ARTICLE 12 - COSTS, EXPENSES AND INDEMNIFICATION 
  

	12.1	Costs and Expenses 

 The Borrower shall pay promptly upon notice from the Agent
all reasonable out-of-pocket costs and expenses of the Agent in connection with the Documents and the establishment and initial syndication of the Credit Facility,
including, without limitation, in connection with preparation, printing, execution and delivery of this Agreement and the other Documents whether or not any Drawdown has been made hereunder, and also including, without limitation, the reasonable
fees and out-of-pocket costs and expenses of Lenders’ Counsel with respect thereto and with respect to advising the Agent and the Lenders as to their rights and
responsibilities under this Agreement and the other Documents. Except for ordinary expenses of the Lenders and the Agent relating to the day-to-day administration of
this Agreement, the Borrower further agrees to pay within 30 days of demand by the Agent all reasonable out-of-pocket costs and expenses in connection with the
preparation or review of waivers, consents and amendments pertaining to this Agreement, and in connection with the establishment of the validity and enforceability of this Agreement and the preservation or enforcement of rights of the Lenders and
the Agent under this Agreement and other Documents, including, without limitation, all reasonable out-of-pocket costs and expenses sustained by the Lenders and the Agent
as a result of any failure by the Borrower to perform or observe any of its obligations hereunder or in connection with any action, suit or proceeding (whether or not an Indemnified Party is a party or subject thereto), together with interest
thereon from and after such 30th day if such payment is not made by such time. 
  

	12.2	General Indemnity 

 In addition to any liability of the Borrower to any Lender or
the Agent under any other provision hereof, the Borrower shall indemnify each Indemnified Party and hold each Indemnified Party harmless against any losses, claims, costs, damages or liabilities (including, without limitation, any expense or cost
incurred in the liquidation and re-deployment of funds acquired to fund or maintain any portion of a Loan and reasonable
out-of-pocket expenses and reasonable legal fees on a solicitor and his own client basis) incurred by the same as a result of or in connection with: 

  -
 70
 - 
  

	 	(a)	any cost or expense incurred by reason of the liquidation or re-deployment in whole or in part of deposits or other funds required by any Lender to fund any Bankers’
Acceptance or to fund or maintain any Loan as a result of the Borrower’s failure to complete a Drawdown or to make any payment, repayment or prepayment on the date required hereunder or specified by it in any notice given hereunder;

  

	 	(b)	subject to permitted or deemed Rollovers and Conversions, the Borrower’s failure to provide for the payment to the Agent for the account of the Lenders of the full principal amount of each Bankers’ Acceptance
on its maturity date; 

  

	 	(c)	the Borrower’s failure to pay any other amount, including without limitation any interest or fee, due hereunder on its due date after the expiration of any applicable grace or notice periods (subject, however, to
the interest obligations of the Borrower hereunder for overdue amounts); 

  

	 	(d)	the Borrower’s repayment or prepayment of a Libor Loan otherwise than on the last day of its Interest Period; 

  

	 	(e)	the prepayment of any outstanding Bankers’ Acceptance before the maturity date of such Bankers’ Acceptance; 

  

	 	(f)	the Borrower’s failure to give any notice required to be given by it to the Agent or the Lenders hereunder; 

  

	 	(g)	the failure of the Borrower to make any other payment due hereunder; 

  

	 	(h)	any inaccuracy or incompleteness of the Borrower’s representations and warranties contained in Article 8; 

  

	 	(i)	any failure of the Borrower to observe or fulfil its obligations under Article 9; 

  

	 	(j)	any failure of the Borrower to observe or fulfil any other Obligation not specifically referred to above; or 

  

	 	(k)	the occurrence of any Default or Event of Default in respect of the Borrower, 

 provided that this Section
shall not apply to any losses, claims, costs, damages or liabilities that arise by reason of the gross negligence or wilful misconduct of the Indemnified Party claiming indemnity hereunder. The provisions of this Section shall survive repayment of
the Obligations. 
  

	12.3	Environmental Indemnity 

 The Borrower shall indemnify and hold harmless the
Indemnified Parties forthwith on demand by the Agent from and against any and all claims, suits, actions, debts, damages, costs, losses, liabilities, penalties, obligations, judgments, charges, expenses and disbursements (including without
limitation, all reasonable legal fees and disbursements on a solicitor and his own client basis) of any nature whatsoever, suffered or incurred by the Indemnified Parties or any of them in connection with the Credit Facility, whether as
beneficiaries under the Documents, as successors in 

  -
 71
 - 
  

 
interest of the Borrower or any of its Subsidiaries, or voluntary transfer in lieu of foreclosure, or otherwise howsoever, with respect to any Environmental Claims relating to the property of the
Borrower or any of its Subsidiaries arising under any Environmental Laws as a result of the past, present or future operations of the Borrower or any of its Subsidiaries (or any predecessor in interest to the Borrower or its Subsidiaries) relating
to the property of the Borrower or its Subsidiaries, or the past, present or future condition of any part of the property of the Borrower or its Subsidiaries owned, operated or leased by the Borrower or its Subsidiaries (or any such predecessor in
interest), including any liabilities arising as a result of any indemnity covering Environmental Claims given to any person by the Lenders or the Agent or a receiver, receiver-manager or similar person
appointed hereunder or under applicable law (collectively, the “Indemnified Third Party”); but excluding any Environmental Claims or liabilities relating thereto to the extent that such Environmental Claims or liabilities arise by
reason of the gross negligence or wilful misconduct of the Indemnified Party or the Indemnified Third Party claiming indemnity hereunder. The provisions of this Section shall survive the repayment of the Obligations. 

 

	12.4	Judgment Currency 

 (1) If for the purpose of obtaining or enforcing judgment
against the Borrower in any court in any jurisdiction, it becomes necessary to convert into any other currency (such other currency being hereinafter in this Section referred to as the “Judgment Currency”) an amount due in Canadian
Dollars or United States Dollars under this Agreement, the conversion shall be made at the rate of exchange prevailing on the Banking Day immediately preceding: 
  

	 	(a)	the date of actual payment of the amount due, in the case of any proceeding in the courts of any jurisdiction that will give effect to such conversion being made on such date; or 

 

	 	(b)	the date on which the judgment is given, in the case of any proceeding in the courts of any other jurisdiction (the date as of which such conversion is made pursuant to this Section being hereinafter in this Section
referred to as the “Judgment Conversion Date”). 

 (2) If, in the case of any proceeding in the court of any
jurisdiction referred to in Section 12.4(1)(b), there is a change in the rate of exchange prevailing between the Judgment Conversion Date and the date of actual payment of the amount due, the Borrower shall pay such additional amount (if any)
as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of Canadian Dollars or United States Dollars, as the case may be, which
could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial order at the rate of exchange prevailing on the Judgment Conversion Date. 

(3) Any amount due from the Borrower under the provisions of Section 12.4(2) shall be due as a separate debt and shall not be affected by
judgment being obtained for any other amounts due under or in respect of this Agreement. 
 (4) The term “rate of exchange” in
this Section 12.4 means the noon rate of exchange for Canadian interbank transactions in Canadian Dollars or United States Dollars, as the case may 

  -
 72
 - 
  

 
be, in the Judgment Currency published by the Bank of Canada for the day in question, or if such rate is not so published by the Bank of Canada, such term shall mean the Equivalent Amount of the
Judgment Currency. 
 ARTICLE 13 - THE AGENT AND ADMINISTRATION OF THE CREDIT FACILITY 

 

	13.1	Authorization and Action 

 (1) Each Lender hereby irrevocably appoints and
authorizes the Agent to be its agent in its name and on its behalf to exercise such rights or powers granted to the Agent or the Lenders under this Agreement to the extent specifically provided herein and on the terms hereof, together with such
powers as are reasonably incidental thereto and the Agent hereby accepts such appointment and authorization. As to any matters not expressly provided for by this Agreement, the Agent shall not be required to exercise any discretion or take any
action, but, subject to Section 14.10, shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority of the Lenders and such instructions shall be
binding upon all Lenders; provided, however, that the Agent shall not be required to take any action which exposes the Agent to liability in such capacity or which could result in the Agent’s incurring any costs and expenses, without provision
being made for indemnity of the Agent by the Lenders against any loss, liability, cost or expense incurred, or to be incurred or which is contrary to this Agreement or applicable law. 

(2) The Lenders agree that all decisions as to actions to be or not to be taken, as to consents or waivers to be given or not to be given, as
to determinations to be made and otherwise in connection with this Agreement and the Documents, shall be made upon the decision of the Majority of the Lenders except in respect of a decision or determination where it is specifically provided in this
Agreement that “all of the Lenders” or “all Lenders” or words to similar effect, or the Agent alone, is to be responsible for same. Each of the Lenders shall be bound by and agrees to abide by and adopt all decisions made as
aforesaid and covenants in all communications with the Borrower to act in concert and to join in the action, consent, waiver, determination or other matter decided as aforesaid. 

 

	13.2	Procedure for Making Loans 

 (1) The Agent shall make Loans available to the
Borrower as required hereunder by debiting the account of the Agent to which the Lenders’ Rateable Portions of such Loans have been credited in accordance with Section 2.12 (or causing such account to be debited) and, in the absence of
other arrangements agreed to by the Agent and the Borrower in writing, by crediting the account of the Borrower or, at the expense of the Borrower, transferring (or causing to be transferred) like funds in accordance with the instructions of the
Borrower as set forth in the Drawdown Notice, Rollover Notice or Conversion Notice, as the case may be, in respect of each Loan; provided that the obligation of the Agent hereunder to effect such a transfer shall be limited to taking such steps as
are commercially reasonable to implement such instructions, which steps once taken shall constitute conclusive and binding evidence that such funds were advanced hereunder in accordance with the provisions relating thereto and the Agent shall not be
liable for any damages, claims or costs which may be suffered by the Borrower and occasioned by the failure of such Loan to reach the designated destination. 

  -
 73
 - 
  

 (2) Unless the Agent has been notified by a Lender at least one Banking Day prior to the
Drawdown Date, Rollover Date or Conversion Date, as the case may be, requested by the Borrower that such Lender will not make available to the Agent its Rateable Portion of such Loan, the Agent may assume that such Lender has made or will make such
portion of the Loan available to the Agent on the Drawdown Date, Rollover Date or Conversion Date, as the case may be, in accordance with the provisions hereof and the Agent may in its sole discretion, but shall be in no way obligated to, in
reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent such Lender shall not have so made its Rateable Portion of a Loan available to the Agent, such Lender agrees to pay to the Agent
forthwith on demand such Lender’s Rateable Portion of the Loan and all reasonable costs and expenses incurred by the Agent in connection therewith together with interest thereon (at the rate payable hereunder by the Borrower in respect of such
Loan or, in the case of funds made available in anticipation of a Lender remitting proceeds of a Bankers’ Acceptance, at the rate of interest per annum applicable to Canadian Prime Rate Loans) for each day from the date such amount is made
available to the Borrower until the date such amount is paid to the Agent; provided, however, that notwithstanding such obligation if such Lender fails to so pay, the Borrower covenants and agrees that, without prejudice to any rights the Borrower
may have against such Lender, it shall repay such amount to the Agent forthwith after demand therefor by the Agent. The amount payable to the Agent pursuant hereto shall be set forth in a certificate delivered by the Agent to such Lender and the
Borrower (which certificate shall contain reasonable details of how the amount payable is calculated) and shall be prima facie evidence thereof, in the absence of manifest error. If such Lender makes the payment to the Agent required herein,
the amount so paid shall constitute such Lender’s Rateable Portion of the Loan for purposes of this Agreement. The failure of any Lender to make its Rateable Portion of any Loan shall not relieve any other Lender of its obligation, if any,
hereunder to make its Rateable Portion of such Loan on the Drawdown Date, Rollover Date or Conversion Date, as the case may be, but no Lender shall be responsible for the failure of any other Lender to make the Rateable Portion of any Loan to be
made by such other Lender on the date of any Drawdown, Rollover or Conversion, as the case may be. 
  

	13.3	Remittance of Payments 

 Except for amounts payable to the Agent for its own
account and subject to Section 2.18, forthwith after receipt of any repayment pursuant hereto or payment of interest or fees pursuant to Article 5 or payment pursuant to Article 7, the Agent shall remit to each Lender its Rateable Portion of
such payment; provided that, if the Agent, on the assumption that it will receive on any particular date a payment of principal, interest or fees hereunder, remits to a Lender its Rateable Portion of such payment and the Borrower fails to make such
payment, each of the Lenders on receipt of such remittance from the Agent agrees to repay to the Agent forthwith on demand an amount equal to the remittance together with all reasonable costs and expenses incurred by the Agent in connection
therewith and interest thereon at the rate and calculated in the manner applicable to the Loan in respect of which such payment is made, or, in the case of a remittance in respect of Bankers’ Acceptances, at the rate of interest applicable to
Canadian Prime Rate Loans for each day from the date such amount is remitted to the Lenders without prejudice to any right such Lender may have against the Borrower. The exact amount of the repayment required to be made by the Lenders pursuant
hereto shall be as set forth in a certificate delivered by the Agent to each Lender, which certificate shall be conclusive and binding for all purposes in the absence of manifest error. 

  -
 74
 - 
  

	13.4	Redistribution of Payment 

 Each Lender agrees that: 

 

	 	(a)	if such Lender exercises any security against or right of counter-claim, set off or banker’s lien or similar right with respect to the property of the Borrower or if under
any applicable bankruptcy, insolvency or other similar law it receives a secured claim and collateral for which it is, or is entitled to exercise any set-off against, a debt owed by it to the Borrower, such
Lender shall apportion the amount thereof proportionately between: 

  

	 	(i)	such Lender’s Rateable Portion of all outstanding Obligations owing by the Borrower (including the face amounts at maturity of Bankers’ Acceptances accepted by the Lenders), which amounts shall be applied in
accordance with Section 13.4(b); and 

  

	 	(ii)	amounts otherwise owed to such Lender by the Borrower, 

 provided that (i) any cash
collateral account held by such Lender as collateral for a letter of credit or bankers’ acceptance (other than a Bankers’ Acceptance) issued or accepted by such Lender on behalf of the Borrower may be applied by such Lender to such amounts
owed by the Borrower to such Lender pursuant to such letter of credit or in respect of any such bankers’ acceptance without apportionment and (ii) these provisions do not apply to: 

 

	 	(A)	a right or claim which arises or exists in respect of a loan or other debt in respect of which the relevant Lender holds a Security Interest which is a Permitted Encumbrance; 

 

	 	(B)	cash collateral provided, or the exercise of rights of counterclaim, set-off or banker’s lien or similar rights, in respect of account positioning arrangements for the
Borrower and its Subsidiaries provided by a Lender in the ordinary course of business or in respect of other cash management services provided by a Lender in the ordinary course of business; or 

 

	 	(C)	any payment to which a Lender is entitled as a result of any credit derivative or other form of credit protection obtained by such Lender; 

 

	 	(b)	 if, in the aforementioned circumstances, such Lender, through the exercise of a right, or the receipt of a
secured claim described in Section 13.4(a) above or otherwise, receives payment of a proportion of the aggregate amount of Obligations due to it hereunder which is greater than the proportion received by any other Lender in respect of the
aggregate Obligations due to the Lenders (having regard to the respective Rateable Portions of the Lenders), such Lender receiving such proportionately greater payment shall purchase, on a non-recourse basis
at par, and make payment for a participation (which shall be deemed to have been done simultaneously with receipt of such payment) in the outstanding Loans of the other 

  -
 75
 - 
  

	 	 
Lender or Lenders so that their respective receipts shall be pro rata to their respective Rateable Portions; provided, however, that if all or part of such proportionately greater payment
received by such purchasing Lender shall be recovered by or on behalf of the Borrower or any trustee, liquidator, receiver or receiver-manager or person with analogous powers from the purchasing Lender, such
purchase shall be rescinded and the purchase price paid for such participation shall be returned to the extent of such recovery, but without interest unless the purchasing Lender is required to pay interest on such amount, in which case each selling
Lender shall reimburse the purchasing Lender pro rata in relation to the amounts received by it. Such Lender shall exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this
Section to share in the benefits of any recovery on such secured claims; and 

  

	 	(c)	if such Lender does, or is required to do, any act or thing permitted by Section 13.4(a) or (b) above, it shall promptly provide full particulars thereof to the Agent. 

 

	13.5	Duties and Obligations 

 Neither the Agent nor any of its directors, officers,
agents or employees (and, for purposes hereof, the Agent shall be deemed to be contracting as agent and trustee for and on behalf of such persons) shall be liable to the Lenders for any action taken or omitted to be taken by it or them under or in
connection with this Agreement except for its or their own gross negligence or wilful misconduct. Without limiting the generality of the foregoing, the Agent: 
  

	 	(a)	may assume that there has been no assignment or transfer by any means by the Lenders of their rights hereunder, unless and until the Agent receives written notice of the assignment thereof from such Lender and the Agent
receives from the assignee an executed Assignment Agreement providing, inter alia, that such assignee is bound hereby as it would have been if it had been an original Lender party hereto; 

 

	 	(b)	may consult with legal counsel (including receiving the opinions of Borrower’s counsel and Lenders’ Counsel required hereunder), independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; 

  

	 	(c)	shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telegram, cable, telecopier or telex) believed by it to be
genuine and signed or sent by the proper party or parties or by acting upon any representation or warranty of the Borrower made or deemed to be made hereunder; 

  

	 	(d)	may assume that no Default or Event of Default has occurred and is continuing unless it has actual knowledge to the contrary; 

  -
 76
 - 
  

	 	(e)	may rely as to any matters of fact which might reasonably be expected to be within the knowledge of any person upon a certificate signed by or on behalf of such person; 

 

	 	(f)	shall not be bound to disclose to any other person any information relating to the Borrower, any of its Subsidiaries or any other person if such disclosure would or might in its opinion constitute a breach of any
applicable law, be in default of the provisions hereof or be otherwise actionable at the suit of any other person; and 

  

	 	(g)	may refrain from exercising any right, power or discretion vested in it which would or might in its reasonable opinion be contrary to any applicable law or any directive or otherwise render it liable to any person, and
may do anything which is in its reasonable opinion necessary to comply with such applicable law. 

 Further, the Agent (i) does not make
any warranty or representation to any Lender nor shall it be responsible to any Lender for the accuracy or completeness of the representations and warranties of the Borrower herein or the data made available to any of the Lenders in connection with
the negotiation of this Agreement, or for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement; (ii) shall not have any duty to ascertain or to enquire as to the performance or
observance of any of the terms, covenants or conditions of this Agreement on the part of the Borrower or to inspect the property (including the books and records) of the Borrower or any of its Subsidiaries; and (iii) shall not be responsible to
any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any instrument or document furnished pursuant hereto. 

 

	13.6	Prompt Notice to the Lenders 

 Notwithstanding any other provision herein, the
Agent agrees to provide to the Lenders, with copies where appropriate, all information, notices and reports required to be given to the Agent by the Borrower, promptly upon receipt of same, excepting therefrom information and notices relating solely
to the role of Agent hereunder. 
  

	13.7	Agent’s and Lenders’ Authorities 

 With respect to its Commitment and
the Drawdowns, Rollovers, Conversions and Loans made by it as a Lender, the Agent shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Agent. Subject to the express
provisions hereof relating to the rights and obligations of the Agent and the Lenders in such capacities, the Agent and each Lender may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower and its
Subsidiaries or any corporation or other entity owned or controlled by any of them and any person which may do business with any of them without any duties to account therefor to the Agent or the other Lenders and, in the case of the Agent, all as
if it was not the Agent hereunder. 
  

	13.8	Lender Credit Decision 

 It is understood and agreed by each Lender that it has
itself been, and will continue to be, solely responsible for making its own independent appraisal of and investigations into the 

  -
 77
 - 
  

 
financial condition, creditworthiness, condition, affairs, status and nature of the Borrower and its Subsidiaries. Each Lender represents to the Agent that it is engaged in the business of making
and evaluating the risks associated with commercial revolving loans or term loans, or both, to corporations similar to the Borrower, that it can bear the economic risks related to the transaction contemplated hereby, that it has had access to all
information deemed necessary by it in making such decision (provided that this representation shall not impair its rights against the Borrower) and that it is entering into this Agreement in the ordinary course of its commercial lending business.
Accordingly, each Lender confirms with the Agent that it has not relied, and will not hereafter rely, on the Agent (i) to check or enquire on its behalf into the adequacy, accuracy or completeness of any information provided by the Borrower or
any other person under or in connection with this Agreement or the transactions herein contemplated (whether or not such information has been or is hereafter distributed to such Lender by the Agent), or (ii) to assess or keep under review on
its behalf the financial condition, creditworthiness, condition, affairs, status or nature of the Borrower or any of its Subsidiaries. Each Lender acknowledges that a copy of this Agreement has been made available to it for review and each Lender
acknowledges that it is satisfied with the form and substance of this Agreement. Each Lender hereby covenants and agrees that, subject to Section 13.4, it will not make any arrangements with the Borrower for the satisfaction of any Loans or
other Obligations without the consent of all the other Lenders. 
  

	13.9	Indemnification of Agent 

 The Lenders hereby agree to indemnify the Agent (to the
extent not reimbursed by the Borrower), on a pro rata basis in accordance with their respective Commitments as a proportion of the aggregate of all outstanding Commitments, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or any
action taken or omitted by the Agent under or in respect of this Agreement in its capacity as Agent; provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs expenses or disbursements resulting from the Agent’s gross negligence or wilful misconduct. If the Borrower subsequently repays all or a portion of such amounts to the Agent, the Agent shall reimburse the Lenders their pro rata
shares (according to the amounts paid by them in respect thereof) of the amounts received from the Borrower. Without limiting the generality of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its portion (determined
as above) of any out-of-pocket expenses (including counsel fees) incurred by the Agent in connection with the preservation of any rights of the Agent or the Lenders
under, or the enforcement of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower. 

 

	13.10	Successor Agent 

 The Agent may, as hereinafter provided, resign at any time by
giving 45 days’ prior written notice thereof to the Lenders and the Borrower. Upon any such resignation, the Lenders shall, after soliciting the views of the Borrower, have the right to appoint another Lender as a successor agent (the
“Successor Agent”) who shall be acceptable to the Borrower, acting reasonably. If no Successor Agent shall have been so appointed by the Lenders and shall have accepted such appointment within 30 days after the retiring
Agent’s giving of notice of resignation, 

  -
 78
 - 
  

 
then the retiring Agent shall, on behalf of the Lenders, appoint a Successor Agent who shall be a Lender acceptable to the Borrower, acting reasonably. Upon the acceptance of any appointment as
Agent 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 thereupon be discharged from its further
duties and obligations as Agent under this Agreement. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Article shall continue to enure to its benefit as to any actions taken or omitted to be taken by it as Agent
or in its capacity as Agent while it was Agent hereunder. 
  

	13.11	Taking and Enforcement of Remedies 

 Each of the Lenders hereby acknowledges that,
to the extent permitted by applicable law, the remedies provided hereunder to the Lenders are for the benefit of the Lenders collectively and acting together and not severally and further acknowledges that its rights hereunder are to be exercised
not severally, but collectively by the Agent upon the decision of the Majority of the Lenders regardless of whether acceleration was made pursuant to Section 10.2. Notwithstanding any of the provisions contained herein, each of the Lenders
hereby covenants and agrees that it shall not be entitled to individually take any action with respect to the Credit Facility, including, without limitation, any acceleration under Section 10.2, but that any such action shall be taken only by
the Agent with the prior written agreement or instructions of the Majority of the Lenders; provided that, notwithstanding the foregoing, if (i) the Agent, having been adequately indemnified against costs and expenses of so doing by the Lenders,
shall fail to carry out any such instructions of a Majority of the Lenders, any Lender may do so on behalf of all Lenders and shall, in so doing, be entitled to the benefit of all protections given the Agent hereunder or elsewhere, and (ii) in
the absence of instructions from the Majority of the Lenders and where in the sole opinion of the Agent the exigencies of the situation warrant such action, the Agent may without notice to or consent of the Lenders or any of them take such action on
behalf of the Lenders as it deems appropriate or desirable in the interests of the Lenders. Each of the Lenders hereby further covenants and agrees that upon any such written consent being given by the Majority of the Lenders, or upon a Lender or
the Agent taking action as aforesaid, it shall cooperate fully with the Lender or the Agent to the extent requested by the Lender or the Agent in the collective realization including, without limitation, and, if applicable, the appointment of a
receiver, or receiver and manager to act for their collective benefit. Each Lender covenants and agrees to do all acts and things and to make, execute and deliver all agreements and other instruments, including, without limitation, any instruments
necessary to effect any registrations, so as to fully carry out the intent and purpose of this Section; and each of the Lenders hereby covenants and agrees that, subject to Section 5.7, Section 13.4 and Section 9.2(a) it has not
heretofore and shall not seek, take, accept or receive any security for any of the obligations and liabilities of the Borrower hereunder or under any other document, instrument, writing or agreement ancillary hereto and shall not enter into any
agreement with any of the parties hereto or thereto relating in any manner whatsoever to the Credit Facility, unless all of the Lenders shall at the same time obtain the benefit of any such security or agreement. 

With respect to any enforcement, realization or the taking of any rights or remedies to enforce the rights of the Lenders hereunder, the Agent
shall be a trustee for each Lender, and all monies received from time to time by the Agent in respect of the foregoing shall be held in trust and shall be trust assets within the meaning of applicable bankruptcy or insolvency legislation and shall
be considered for the purposes of such legislation to be held separate and apart from the other assets 

  -
 79
 - 
  

 
of the Agent, and each Lender shall be entitled to their Rateable Portion of such monies. In its capacity as trustee, the Agent shall be obliged to exercise only the degree of care it would
exercise in the conduct and management of its own business and in accordance with its usual practice concurrently employed or hereafter instituted for other substantial commercial loans. 

 

	13.12	Reliance Upon Agent 

 The Borrower shall be entitled to rely upon any certificate,
notice or other document or other advice, statement or instruction provided to it by the Agent pursuant to this Agreement, and the Borrower shall generally be entitled to deal with the Agent with respect to matters under this Agreement which the
Agent is authorized to deal with without any obligation whatsoever to satisfy itself as to the authority of the Agent to act on behalf of the Lenders and without any liability whatsoever to the Lenders for relying upon any certificate, notice or
other document or other advice, statement or instruction provided to it by the Agent, notwithstanding any lack of authority of the Agent to provide the same. 
  

	13.13	No Liability of Agent 

 The Agent shall have no responsibility or liability to the
Borrower on account of the failure of any Lender to perform its obligations hereunder (unless such failure was caused, in whole or in part, by the Agent’s failure to observe or perform its obligations hereunder), or to any Lender on account of
the failure of the Borrower or any Lender to perform its obligations hereunder. 
  

	13.14	The Agent and the Defaulting Lenders 

 (1) Each Defaulting Lender shall be
required to provide to the Agent cash in an amount, as shall be determined from time to time by the Agent in its discretion, equal to all obligations of such Defaulting Lender to the Agent that are owing or may become owing pursuant to this
Agreement, including such Defaulting Lender’s obligation to pay its Rateable Portion of any indemnification or expense reimbursement amounts not paid by the Borrower. Such cash shall be held by the Agent in one or more cash collateral accounts,
which accounts shall be in the name of the Agent and shall not be required to be interest bearing. The Agent shall be entitled to apply the foregoing cash in accordance with Sections 13.9 and 13.14(3). 

(2) In addition to the indemnity and reimbursement obligations noted in Section 13.9, the Lenders agree to indemnify the Agent (to the
extent not reimbursed by the Borrower and without limiting the obligations of the Borrower hereunder) rateably according to their respective Rateable Portions (and in calculating the Rateable Portion of a Lender, ignoring the Commitments of
Defaulting Lenders) any amount that a Defaulting Lender fails to pay the Agent and which is due and owing to the Agent pursuant to Section 13.9. Each Defaulting Lender agrees to indemnify each other Lender for any amounts paid by such Lender
and which would otherwise be payable by the Defaulting Lender. 
 (3) The Agent shall be entitled to set off any Defaulting Lender’s
Rateable Portion of all payments received from the Borrower against such Defaulting Lender’s obligations to fund payments and Loans required to be made by it and to purchase participations required to be purchased by it in each case under this
Agreement and the other Documents. The Agent shall be entitled to withhold and deposit in one or more non-interest bearing cash collateral accounts in the 

  -
 80
 - 
  

 
name of the Agent all amounts (whether principal, interest, fees or otherwise) received by the Agent and due to a Defaulting Lender pursuant to this Agreement, which amounts shall be used by the
Agent: 
  

	 	(a)	first, to reimburse the Agent for any amounts owing to it by the Defaulting Lender pursuant to any Document; 

  

	 	(b)	second, to repay on a pro rata basis any (i) Loans made by a Lender pursuant to Section 14.2(4) in order to fund a shortfall created by a Defaulting Lender which repayment shall be in the form of an assignment
by each such Lender of such Loan to the Defaulting Lender against receipt of such repayment, and (ii) any payments made by a Lender pursuant to Section 13.14(2) in order to fund a shortfall created by a Defaulting Lender;

  

	 	(c)	third, to cash collateralize all other obligations of such Defaulting Lender to the Agent owing pursuant to this Agreement in such amount as shall be determined from time to time by the Agent in its discretion,
including such Defaulting Lender’s obligation to pay its Rateable Portion of any indemnification or expense reimbursement amounts not paid by the Borrower; and 

 

	 	(d)	fourth, to fund from time to time the Defaulting Lender’s Rateable Portion of Loans. 

 (4)
For greater certainty and in addition to the foregoing, neither the Agent nor any of its Affiliates nor any of their respective shareholders, officers, directors, employees, agents or representatives shall be liable to any Lender (including, without
limitation, a Defaulting Lender) for any action taken or omitted to be taken by it in connection with amounts payable by the Borrower to a Defaulting Lender and received and deposited by the Agent in a cash collateral account and applied in
accordance with the provisions of this Agreement, save and except for the gross negligence or wilful misconduct of the Agent as determined by a final non-appealable judgement of a court of competent jurisdiction. 

 

	13.15	Article for Benefit of Agent and Lenders 

 The provisions of this Article 13 which
relate to the rights and obligations of the Lenders to each other or to the rights and obligations between the Agent and the Lenders shall be for the exclusive benefit of the Agent and the Lenders, and, except to the extent provided in
Sections 13.1, 13.2, 13.6, 13.10, 13.11, 13.12, 13.13. 13.14 and this Section 13.15, the Borrower shall not have any rights or obligations thereunder or be entitled to rely for any purpose upon such provisions. Any Lender may waive in
writing any right or rights which it may have against the Agent or the other Lenders hereunder without the consent of or notice to the Borrower. 

ARTICLE 14 - GENERAL 
  

	14.1	Exchange and Confidentiality of Information 

 (1) The Borrower agrees that the
Agent and each Lender may provide any assignee or participant or any bona fide prospective assignee or participant pursuant to Sections 14.6 or 14.7 with any information concerning the financial condition of the Borrower and its

 81
 - 
  

 
provided such party agrees with the Agent or such Lender for the benefit of the Borrower to be bound by a like duty of confidentiality to that contained in this Section.

provided and to be provided to them by the Borrower pursuant hereto (the “Information”) and agrees to use all reasonable efforts to prevent the disclosure thereof provided, however, that: 

 

	 	(a)	the Agent and each of the Lenders may disclose all or any part of the Information if, in their reasonable opinion, such disclosure is required in connection with any actual or threatened judicial, administrative or
governmental proceedings (including proceedings initiated under or in respect of this Agreement) or upon the request of its independent auditors or a Governmental Authority having jurisdiction over it; 

 

	 	(b)	the Agent and each of the Lenders shall incur no liability in respect of any Information required to be disclosed by any applicable law or regulation, or by applicable order, policy or directive having the force of law,
to the extent of such requirement; 

  

	 	(c)	the Agent and each of the Lenders may provide Lenders’ Counsel and their other agents and professional advisors and insurers and reinsurers and any actual or prospective counterparty (or its advisors) to any
securitization, swap or derivative transaction relating to the Borrower, its Subsidiaries and the Obligations with any Information; provided that such persons shall be under a like duty of confidentiality to that contained in this Section;

  

	 	(d)	the Agent and each of the Lenders shall incur no liability in respect of any Information: (i) which is or becomes readily available to the public (other than by a breach hereof) or which has been made readily
available to the public by the Borrower or its Subsidiaries, (ii) which the Agent or the relevant Lender can show was, prior to receipt thereof from the Borrower, lawfully in the Agent’s or Lender’s possession and not then subject to
any obligation on its part to the Borrower to maintain confidentiality, or (iii) which the Agent or the relevant Lender received from a third party who was not, to the knowledge of the Agent or such Lender, under a duty of confidentiality to
the Borrower at the time the information was so received; 

  

	 	(e)	the Agent and each of the Lenders may disclose the Information to other financial institutions and other persons in connection with the syndication by the Agent or Lenders of the Credit Facility or the granting by a
Lender of a participation in the Credit Facility where such financial institution or other person agrees to be under a like duty of confidentiality to that contained in this Section; 

 

	 	(f)	 the Agent and each Lender may provide any Affiliate thereof with the Information to the extent reasonably
required to be disclosed thereto; provided that each such Affiliate shall be under a like duty of confidentiality to that contained in this Section 14.1 and further provided that the Agent or the Lender, as the case may be, providing

the Information shall be responsible for any breach by its Affiliate of the aforementioned like duty of confidentiality; and 

 

	 	(g)	the Agent and each of the Lenders may disclose all or any part of the Information so as to enable the Agent and the Lenders to initiate any lawsuit against the Borrower or to defend any lawsuit commenced by the Borrower

(3) With respect to each Lender, the provisions of this Article 14 shall survive repayment of the Obligations to such Lender and shall
continue for a period of two years after such Lender ceases to be a Lender hereunder. 
  

	14.2	Nature of Obligation under this Agreement; Defaulting Lenders 

 (1) The
obligations of each Lender and of the Agent under this Agreement are several. The failure of any Lender to carry out its obligations hereunder shall not relieve the other Lenders, the Agent or the Borrower of any of their respective obligations
hereunder. 
 (2) Without derogating from the operation of Section 13.14 and this Section 14.2, neither the Agent nor any Lender
shall be responsible for the obligations of any other Lender hereunder. 
 (3) Notwithstanding any provision of this Agreement to the
contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender: 
  

	 	(a)	the standby fees payable pursuant to Section 5.6 shall cease to accrue on the unused portion of the Commitment of such Defaulting Lender; 

 

	 	(b)	a Defaulting Lender shall not be included in determining whether, and the Commitment and the Rateable Portion of the Outstanding Principal of such Defaulting Lender shall not be included in determining whether, all
Lenders or the Majority of the Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 14.10), provided that any waiver, amendment or modification requiring the consent of all
Lenders or each affected Lender that (i) affects such Defaulting Lender differently than other affected Lenders, (ii) increases the Commitment of such Defaulting Lender, (iii) extends the Maturity Date applicable to such Defaulting
Lender, (iv) decreases the Applicable Pricing Rate applicable to such Defaulting Lender or (v) postpones, reduces or waives any principal payment due to such Defaulting Lender hereunder shall in each case shall require the consent of such
Defaulting Lender; and 

  

	 	(c)	for the avoidance of doubt, the Borrower shall retain and reserve its other rights and remedies respecting each Defaulting Lender. 

(4) Should any Lender fail to fund its Rateable Portion of a Loan hereunder, then each other Lender shall fund a portion of such defaulted
amount in an amount equal to such other 

  -
 83
 - 
  

 
Lender’s Rateable Portion (and in calculating the Rateable Portion of a Lender, ignoring the Commitments of Defaulting Lenders) of such unfunded portion; provided that, for certainty, no
Lender shall be obligated by this Section to make or provide Loans in excess of its Commitment. 
 (5) If any Lender shall cease to be a
Defaulting Lender, then, upon becoming aware of the same, the Agent shall notify the other Lenders and (in accordance with the written direction of the Agent) such Lender (which has ceased to be a Defaulting Lender) shall purchase, and the other
Lenders shall on a rateable basis sell and assign to such Lender, portions of such Loans equal in total to such Lender’s Rateable Portion thereof without regard to Section 14.2(4). 

(6) Each Defaulting Lender hereby indemnifies the Borrower for any losses, claims, costs, damages or liabilities (including reasonable
out-of-pocket expenses and reasonable legal fees on a solicitor and his own client basis) incurred by the Borrower as a result of such Defaulting Lender failing to comply with the terms of this Agreement including any failure to fund its portion of
any Loans required to be made by it hereunder; provided that this Section shall not apply to any losses, claims, costs, damages or liabilities that arise by reason of the gross negligence or wilful misconduct of the Borrower.

 This Agreement shall be governed by and construed in accordance
with the laws of the Province of Alberta and the laws of Canada applicable therein, without prejudice to or limitation of any other rights or remedies available under the laws of any jurisdiction where property or assets of the Borrower may be
found. 
  

	14.5	Benefit of the Agreement 

 This Agreement shall enure to the benefit of and be
binding upon the Borrower, the Lenders, the Agent and their respective successors and permitted assigns. 
  

	14.6	Assignment 

 Any Lender may, without consent during the continuance of an Event of
Default and at all other times with the prior written consent of the Borrower and the Agent, which consents shall not be unreasonably withheld or delayed, sell, assign, transfer or grant an interest in its Commitment, its Rateable Portion of the
Loans and its rights under the Documents; provided that, except during the continuance of an Event of Default, without the consent of the Borrower and the Agent, no Lender shall sell, assign, transfer or grant an interest in any Commitment, Loan or
Document if the effect thereof would be to have a Lender with a Commitment of less than Cdn.$25,000,000 (such amount to be reduced in proportion to any partial reductions in the Credit Facility), and further provided that, it shall be a precondition
to any such sale, assignment, transfer or grant that the contemplated assigning Lender shall have paid to the Agent, for the Agent’s own account, a transfer fee of Cdn.$3,500.00. Upon any such sale, assignment, transfer or grant, the assigning
Lender shall have no further obligation hereunder with respect to such interest. Upon any such sale, assignment, transfer or grant, the assigning Lender, the new Lender, the Agent and the Borrower shall execute and deliver an Assignment Agreement.
Subject to the provisions of Section 9.2(b), the Borrower shall not assign its rights or obligations hereunder without the prior written consent of all of the Lenders. Notwithstanding the foregoing, any Lender may at any time grant a Security
Interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any Security Interest to secure obligations to a U.S. Federal Reserve Bank; provided that no such grant of

  -
 86

a Security Interest shall release a Lender from any of its obligations hereunder or substitute any holder of such Security Interest for such Lender as a party hereto. 

 

	14.7	Participations 

 Any Lender may, without the consent of the Borrower, grant one or
more participations in its Commitment and its Rateable Portion of the Loans to other persons, provided that the granting of such a participation: (a) shall be at such Lender’s own cost and (b) shall not affect the obligations of such
Lender hereunder nor shall it increase the costs to the Borrower hereunder or under any of the other Documents. For certainty, no participant of a Lender shall have any rights or benefits hereunder, nor shall the consent or approval of such
participant be required for any consent, approval or waiver from such Lender. 
  

	14.8	Severability 

 Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall not invalidate the remaining provisions hereof and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 

 

	14.9	Whole Agreement 

 This Agreement and the other Documents constitute the whole and
entire agreement between the parties hereto regarding the subject matter hereof and thereof and cancel and supersede any prior agreements (including, without limitation, any commitment letters), undertakings, declarations, commitments,
representations, written or oral, in respect thereof. 
  

	14.10	Amendments and Waivers
