Each Lender is liable to, and by entering into this Agreement agrees to, indemnify and hold harmless the Fronting Lender in relation to the Fronting Lender's liability as issuer of a Fronted Letter of Credit to the extent of such Lender's Proportionate Share of such liability. The Principal Outstanding under the Revolver Facility shall be adjusted in the circumstances and in the manner contemplated by Section 11.7 in order to reflect the issuance of Fronted Letters of Credit by the Fronting Lender on behalf of the Lenders. (b) Documents and Payment Demands. WFT and each Lender hereby authorize the Fronting Lender to review on behalf of each Lender each document presented under a Fronted Letter of Credit. The determination of the Fronting Lender as to the conformity of any document presented under a Fronted Letter of Credit to the requirements of such Fronted Letter of Credit shall be conclusive and binding on WFT and each Lender, provided the Fronting Lender acts in accordance with the standards of reasonable care specified in the Uniform Customs. The Fronting Lender shall, within a reasonable time after its receipt thereof, examine all documents purporting to represent a demand for payment under any Fronted Letter of Credit. (c) Payment of Amounts Drawn under Fronted Letter of Credit. WFT shall reimburse the Fronting Lender on demand for any amount paid by the Fronting Lender upon a drawing under a Fronted Letter of Credit (the "drawn amount"). The amount so payable by WFT shall include interest on the drawn amount at the rate per annum applicable to Prime Rate Advances (if the drawn amount was in Canadian Dollars) or the rate per annum applicable to US Base Rate Advances (if the drawn amount was in US Dollars), for the period from and including the date the drawn amount was paid by the Fronting Lender to but excluding the date of reimbursement of the drawn amount (together with interest) by WFT. If WFT has failed to reimburse the Fronting Lender for a drawn amount (together with interest) by 1:00 p.m. (Toronto time) on the second Business Day following the date of demand by the Fronting Lender (the "demand date"), then:

Each such notice shall specify whether the Letter of Credit is to be a POA Letter of Credit or a Fronted Letter of Credit.

(a) Indemnity. In addition to amounts payable as elsewhere provided in this Article, WFT hereby agrees to protect, indemnify, pay and save the Agent, the Fronting Lender and each other Lender and their respective directors, officers, employees, agents and representatives harmless from and against any and all claims, demands, liabilities, damages, losses, costs, charges and expenses (including legal fees and expenses) which the indemnitee may incur or be subject to as a consequence, direct or indirect, of the issuance of any Letter of Credit, or the failure of the indemnitee to honour a drawing under any Letter of Credit as a result of any act or omission, whether rightful or wrongful, of any present or future de jure or de facto Governmental Authority (all such acts or omissions called in this Section, "Government Acts"). (b) Risk.

It is expressly understood and agreed that the respective rights and remedies of the Agent and the Lenders under this Agreement are cumulative and are in addition to and not in substitution for any rights or remedies provided by law or by equity; and any single or partial exercise by the Agent or the Lenders of any right or remedy for a default or breach of any term, covenant, condition or agreement contained in this Agreement shall not be deemed to be a waiver of or to alter, affect or prejudice any other right or remedy to which the Agent or the Lenders may be lawfully entitled for such default or breach. 8.5 Right of Set-Off. In addition to any rights now or hereafter granted under applicable Law and not by way of limitation of any such rights, after the occurrence of an Event of Default and the Obligations becoming due and payable, except where there is an agreement to the contrary, each Lender is hereby authorized by each Borrower at any time or from time to time without notice to such Borrower or to any other person, any such notice being hereby expressly waived to the extent permitted by Law, to set off and to appropriate and to apply any and all deposits (general or special), time or demand, in each case whether matured or unmatured (and any other indebtedness) at any time held or owing by such Lender to or for the credit or account of such Borrower against and on account of the obligations of such Borrower to such Lender, including all claims of any nature or description arising out of or connected with this Agreement or any of the other Credit Facility Documents, and although such obligations and liabilities or any of them shall be contingent and unmatured. For greater certainty, the right of set-off conferred upon the Lenders under this Section shall not constitute a security interest in respect of any property of any Borrower.

- 86 - 1380-6618-2422.9 8.6 Currency Conversion After Acceleration. At any time following the occurrence of an Event of Default and the Obligations becoming due and payable, each Lender shall be entitled to convert, with two Business Days' prior notice to the Borrowers, its unpaid and outstanding US Dollar Advances, or any of them, to Prime Rate Advances. Any such conversion shall be calculated so that the resulting Prime Rate Advances shall be the Canadian Dollar Equivalent on the date of conversion of the amount of US Dollars so converted. Any accrued and unpaid interest denominated in US Dollars at the time of any such conversion shall be similarly converted to Canadian Dollars, and such Prime Rate Advances and accrued and unpaid interest thereon shall thereafter bear interest in accordance with Article 3. ARTICLE 9 CHANGES IN CIRCUMSTANCES; TAXES 9.1 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable lending office to make, maintain or fund Accommodations whose interest is determined by reference to any Benchmark, or to determine or charge interest rates based upon any Benchmark, then, upon notice thereof by such Lender to the applicable Borrower (an "Illegality Notice"), (i) any obligation of such Lender to make or continue such Accommodation, or to effect a Rollover of or a Conversion into a Benchmark Advance shall be suspended, and (ii) if such notice asserts the illegality of such Lender making or maintaining US Base Rate Advances or Prime Rate Advances, the interest rate on which is determined by reference to the Term SOFR component of the US Base Rate, or the Adjusted Term CORRA component of the Prime Rate, as applicable, the interest rate on which US Base Rate Advances or Prime Rate Advances, as applicable, of such Lender shall, if necessary to avoid such illegality, be determined by the Agent and the applicable Borrower without reference to the Term SOFR component of the US Base Rate or the Adjusted Term CORRA component of the Prime Rate, as applicable, in each case until such Lender notifies the Agent and the applicable Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of an Illegality Notice, the applicable Borrower or Borrowers shall, upon demand from such Lender (with a copy to the Agent), prepay or, if applicable, convert each affected Benchmark Advance of such Lender to an applicable Benchmark Fallback Advance, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Benchmark Advances to such day, or immediately, if such Lender may not lawfully continue to maintain such Benchmark Advances. Upon any such prepayment or Conversion, the applicable Borrower or Borrowers shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to this Agreement. 9.2 Suspension of US Base Rate Advances. If a Canadian Lender or an Term Lender determines in good faith, and notifies the Agent in writing, that by reason of circumstances affecting financial markets inside or outside Canada, such Lender is unable to fund US Dollar Advances in Canada, then it shall so notify WFT and all Canadian Lenders and Term Lenders, and the right of WFT to request US Base Rate Advances shall be suspended. 9.3 Temporary Market Disruption.

Upon a Lender having determined that it is entitled to Compensation, the Agent shall promptly notify the relevant Borrower and shall provide such Borrower with a certificate of the Lender setting forth the amount of the Compensation and the basis for it. In preparing such certificate the Lender shall not be required to "match" or isolate particular transactions or credit facilities, shall be entitled to use estimates and averages and shall act in a commercially reasonable manner.

A certificate as to the amount of such payment or liability delivered to such Borrower by a Lender (with a copy to the Agent), or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent demonstrable error. (d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Borrower to a Governmental Authority, such Borrower shall deliver to the Agent, the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent.

In addition, any Lender, if requested by WFT, WFUS or the Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by WFT, WFUS or the Agent as will enable WFT, WFUS or the Agent to determine whether or not such Lender is subject to withholding or information reporting requirements.

Each Lender also acknowledges that it will, independently and without reliance upon the Agent and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

Unless the Agent shall have received notice from a Lender prior to the relevant date that such Lender will not make available to the Agent the amount required to be made available by such Lender in respect of an Advance, the Agent may assume that such Lender has made such amount available to the Agent on such date in accordance with this Agreement and the Agent may, in reliance upon such assumption, make available to the applicable Borrower on such date a corresponding amount. If and to the extent such Lender shall not have so made such amount available to the Agent, such Lender shall pay such corresponding amount to the Agent, forthwith on demand. If such Lender shall pay such corresponding amount to the Agent, the amount so paid shall constitute such Lender's share of the relevant Accommodation. If such Lender shall not pay such corresponding amount to the Agent forthwith on demand, the applicable Borrower shall pay such corresponding amount to the Agent forthwith on demand and each Borrower hereby agrees and acknowledges that any such amount received and so reimbursed would not and will not constitute an Accommodation hereunder. The Agent shall also be entitled to recover from such Lender, or if such Lender fails to make payment, the applicable Borrower, interest (without duplication of interest otherwise payable hereunder) on such corresponding amount, for each day from the date such amount is made available to such Borrower until the date such amount is paid to the Agent, in the case of a repayment by the Lender, at a rate determined by the Agent (such rate to be conclusive and binding on such Lender) in accordance with such Agent's usual banking

The Agent may resign at any time by giving 30 days' written notice thereof to the Lenders and the Borrowers. Upon receipt of any such notice of resignation, the Lenders shall have the right to appoint a successor Agent. A successor Agent shall be a Canadian chartered bank approved by the Borrowers (such approval not to be unreasonably withheld). If no successor Agent shall have been so appointed by the Lenders and shall have accepted such appointment within 30 days after delivery of the notice of resignation of the retiring Agent, the retiring Agent, on behalf of the Lenders, shall use reasonable commercial efforts to appoint a successor Agent, which shall be a Lender (or an affiliate of a Lender) approved by the Borrowers (such approval not to be unreasonably withheld). 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, the retiring Agent shall be discharged from its duties and obligations under this Agreement, and the Lender which is such successor Agent shall thereupon become the Issuing Lender hereunder. After any resignation or removal of the Agent, the provisions of this Article shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

(a) Any amendment or waiver of any provision of this Agreement or of any of the other Credit Facility Documents, any consent to any departure by a Borrower therefrom, and any consent or approval contemplated to be given by the Lenders under this Agreement, shall be effective and binding on the Lenders only if in writing and signed by the Majority Lenders (or by the Agent with the consent of the Majority Lenders), except as provided in paragraph (g) below. Notwithstanding the foregoing, no amendment, waiver or consent shall, unless in writing and signed by all the Lenders (or by the Agent with the consent of all the Lenders): (i) waive any of the conditions specified in Article 5; (ii) reduce the principal of, or interest on or discount rate applicable to, the Accommodations or any fees hereunder;

- 101 - 1380-6618-2422.9 11.6 Expenses. The Borrowers shall promptly pay all reasonable costs and expenses of the Agent and the Lenders, including without limitation all reasonable out-of-pocket expenses and disbursements of the Agent and the Lenders and the reasonable fees and expenses of counsel for the Agent or the Lenders, incurred in connection with the preparation, negotiation, execution, registration and administration of this Agreement, the other Credit Facility Documents or any agreement or instrument contemplated hereby or thereby and the carrying out of due diligence in connection with the transactions contemplated hereby, whether or not the transactions contemplated hereunder are completed or any Accommodations are made, or in connection with any requested amendments, waivers or consents or matters initiated by any Borrower pursuant to or in respect of the provisions hereof. The Borrowers shall, subject to applicable Law, promptly pay all costs and expenses of the Agent and the Lenders, including without limitation all out-of-pocket expenses and disbursements of the Agent and the Lenders and the fees and expenses of counsel for the Agent or the Lenders (on a solicitor and client basis), incurred in connection with the enforcement or preservation of rights under this Agreement, the other Credit Facility Documents or any agreement or instrument contemplated hereby or thereby or the collection of Borrowings or any litigation, proceeding or dispute to which the Agent or a Lender is a named party in any way relating to Borrowings. The Borrowers shall pay interest on any amount due under this Section that remains unpaid more than two Business Days after the Agent notifies the Borrowers of such amount, at the Prime Rate plus 2.0% per annum (in the case of an amount in Canadian Dollars) or at the US Base Rate plus 2.0% per annum (in the case of an amount in US Dollars), until such amount is paid. 11.7 Sharing of Payments; Swingline and Fronting Lenders. Upon the occurrence of an Event of Default, adjustments shall be made among the Lenders as set forth below: (a) Unless the Swingline Lenders and the Majority Lenders agree otherwise, if an Event of Default occurs, then each of the Swingline Lenders will promptly request the Agent on behalf of WFT and WFUS, as applicable (and for this purpose the Swingline Lenders are irrevocably authorized by WFT and WFUS respectively to do so) for an Advance: (i) by way of a Prime Rate Advance or a US Base Rate Advance from the Canadian Lenders pursuant to Article 3 to repay to the WFT Swingline Lender the applicable outstanding WFT Swingline Advances; and (ii) by way of a NY Prime Rate Advance from the US Lenders pursuant to Article 3 to repay to the WFUS Swingline Lender the applicable outstanding WFUS Swingline Advances. The Canadian Lenders are irrevocably directed by WFT or WFUS, as applicable, to make any Prime Rate Advance, US Base Rate Advance or NY Prime Rate Advance (as applicable) if so requested by such Swingline Lender and pay the proceeds thereof directly to the Agent, for the account of such Swingline Lender. At all times thereafter the Commitment of such Swingline Lender to make Swingline Advances under Section 2.10 shall be terminated and the Canadian Lenders or the US Lenders, as the case shall be, shall make such adjusting payments amongst themselves in the manner contemplated by Section 11.8 as

If, after the occurrence of an Event of Default, any Letter of Credit is drawn upon which results in a payment by the Fronting Lender thereunder (in this Section, an "LC Payment"), the Fronting Lender will promptly request the Agent on behalf of WFT (and for this purpose the Fronting Lender is irrevocably authorized by WFT to do so) for an Advance by way of a Prime Rate Advance or US Base Rate Advance (as applicable) from the Canadian Lenders pursuant to Article 3 to reimburse the Fronting Lender for such LC Payment and the foregoing provisions of this paragraph (a) shall equally apply to each such further Advance. Each Canadian Lender agrees to pay to the Agent for the account of the WFT Swingline Lender such Canadian Lender's rateable portion of each Advance requested by the WFT Swingline Lender on behalf of WFT to repay WFT Swingline Advances made by the WFT Swingline Lender. Each US Lender agrees to pay to the Agent for the account of the WFUS Swingline Lender such US Lender's rateable portion of each Advance requested by the WFUS Swingline Lender on behalf of WFUS to repay WFUS Swingline Advances made by the WFUS Swingline Lender. Each Canadian Lender agrees to pay to the Agent for the account of the Fronting Lender such Canadian Lender's rateable portion of each Advance requested by the Agent on behalf of WFT to repay LC Payments made by the Fronting Lender. (b) Except as provided in paragraph (c) below, the obligations of each Lender under paragraph (a) are unconditional, shall not be subject to any qualification or exception whatsoever and shall be performed in accordance with the terms and conditions of this Agreement under all circumstances, including: (i) any lack of validity or enforceability of the obligations of WFT; (ii) the occurrence of any Default or Event of Default or the exercise of any rights by the Agent under Section 8.2; and (iii) the absence of any demand for payment being made, any proof of claim being filed, any proceeding being commenced or any judgment being obtained by the Swingline Lender or the Fronting Lender against WFT or WFUS, as applicable. (c) If a Lender (a "Defaulting Lender") fails to make payment on the due date therefor of any amount due from it for the account of the Swingline Lender or the Fronting Lender pursuant to paragraph (a) above (the balance thereof for the time being unpaid being referred to in this paragraph (c) as an "overdue amount") then, until the Swingline Lender or the Fronting Lender has received payment of that amount (plus interest as provided below) in full (and without in any way limiting the rights of the Swingline Lender or the Fronting Lender in respect of such failure): (i) the Swingline Lender or the Fronting Lender shall be entitled to receive any payment which the Defaulting Lender would otherwise have been entitled to receive in respect of the Revolver Facility or otherwise in respect of any Credit Facility Document; and (ii) the overdue amount shall bear interest payable by the Defaulting Lender to the Swingline Lender or the Fronting Lender at the rate payable by WFT

- 103 - 1380-6618-2422.9 or WFUS in respect of the Accommodations which gave rise to such overdue amount. (d) If for any reason an Advance may not be made pursuant to paragraph (a) to reimburse the Swingline Lender or the Fronting Lender as contemplated thereby, then promptly upon receipt of notification of such fact from the Agent, each Canadian Lender or US Lender, as applicable, shall deliver to the Agent for the account of the Swingline Lender or the Fronting Lender in immediately available funds the purchase price for such Canadian Lender's or US Lender's participation interest in the unreimbursed Swingline Advances or LC Payments (including interest then accrued thereon and unpaid by WFT or WFUS, as the case may be). Without duplication, each Canadian Lender or US Lender, as applicable, shall, upon demand by the Swingline Lender or the Fronting Lender made to the Agent, deliver to the Agent for the account of the applicable Swingline Lender or the Fronting Lender interest on such Canadian Lender's or US Lender's rateable portion from the date of payment by the Swingline Lender or the Fronting Lender of such unreimbursed Swingline Advances or LC Payments until the date of delivery of such funds to the Swingline Lender or the Fronting Lender by such Canadian Lender or US Lender at a rate per annum equal to the Federal Funds Rate (if reimbursement is to be made in US Dollars) or one month Term CORRA (if reimbursement is to be made in Canadian Dollars) for such period. Such payment shall only, however, be made by the relevant Canadian Lenders or US Lenders in the event and to the extent the Swingline Lender or the Fronting Lender has not been reimbursed in full by WFT or WFUS, as applicable, for interest on the amount of such unreimbursed Swingline Advances or LC Payments. (e) The Swingline Lender or the Fronting Lender shall, forthwith upon its receipt of any reimbursement (in whole or in part) by WFT or WFUS, as applicable, for any unreimbursed Swingline Advances or LC Payments in relation to which other Canadian Lenders or US Lenders, as applicable, have purchased a participation interest pursuant to paragraph (d), or of any other amount from WFT or WFUS or any other person in respect of such payment (other than pursuant to Section 2.14), transfer to such other Canadian Lender or US Lender such other Canadian Lender's or US Lender's rateable share of such reimbursement or other amount. In the event that any receipt by a Swingline Lender or the Fronting Lender of any reimbursement or other amount from WFT or WFUS is found to have been a transfer in fraud of creditors or a preferential payment under any applicable insolvency legislation or is otherwise required to be returned, such Canadian Lender or US Lender shall promptly return to the Swingline Lender or the Fronting Lender any portion of such reimbursement or other amount previously transferred to it by the Swingline Lender or the Fronting Lender, without interest to the extent that interest is not payable by the Swingline Lender or the Fronting Lender in connection therewith. 11.8 Sharing Generally. In the event that: (a) any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off pursuant to Section 8.5 or at law or equity, or otherwise) on account of any Accommodation made by it under a Credit Facility

- 104 - 1380-6618-2422.9 (other than Compensation paid to it) in excess of its rateable share of payments on account of such Accommodation; or (b) without regard to outstanding Compensation, any Lender shall at the time of acceleration of the outstanding Accommodations have outstanding Accommodations under a Credit Facility which are less than its rateable share of all outstanding Accommodations under such Credit Facility; then such Lender shall forthwith purchase from the other Lenders under such Credit Facility such participations in the Accommodations made by such other Lenders as shall be necessary to cause such purchasing Lender to share the excess payment or be owed the outstanding Accommodations rateably with such other Lenders. In the case of paragraph (a) of this Section, if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each other Lender shall be rescinded and each relevant Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such other Lender's rateable share (according to the proportion that the amount such other Lender's required repayment bears to the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. Any Lender purchasing a participation from another Lender pursuant to this Section may, to the fullest extent permitted by Law, exercise all its rights of payment (including the right of set- off) with respect to such participation as fully as if such Lender were a direct creditor of the Borrowers in the amount of such participation. 11.9 Erroneous Payments. (a) If the Agent: (i) notifies a Lender or any Person who has received funds on behalf of a Lender (any such Lender or other recipient (and each of their respective successors and assigns), a "Payment Recipient") that the Agent, has determined in its sole discretion (whether or not after receipt of any notice under Section 11.9(b)) that any funds (as set forth in such notice) received by such Payment Recipient from the Agent or any of its respective Affiliates were erroneously or mistakenly transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender or other Payment Recipient on its behalf) (any such funds, whether transmitted or received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an "Erroneous Payment"); and (ii) demands in writing the return of such Erroneous Payment (or a portion thereof), such Erroneous Payment shall at all times remain the property of the Agent, pending its return or repayment as contemplated in this Section 11.9 and held in trust for the benefit of the Agent, and such Lender shall (or, with respect to any Payment Recipient who received such funds on its behalf, shall cause such Payment Recipient to) promptly, but in no event later than two Business Days

A notice of the Agent to any Payment Recipient under this Section 11.9(a) shall be conclusive, absent manifest error. (b) Without limiting Section 11.9(a), each Payment Recipient hereby further agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Agent (or any of its respective Affiliates): (i) that is in a different amount than, or on a different date from, that specified in this Agreement or in a notice of payment, prepayment or repayment sent by the Agent (or any of its respective Affiliates) with respect to such payment, prepayment or repayment; (ii) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Agent (or any of its respective Affiliates); or (iii) that such Payment Recipient otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part) in each case, then in each such case: (iv) such Payment Recipient acknowledges and agrees that an error and mistake shall be presumed to have been made (absent written confirmation from the Agent to the contrary) (in the case of paragraphs (i) and (ii) above), or an error and mistake has been made (in the case of paragraph (iii) above), in each case, with respect to such payment, prepayment or repayment; and (v) such Lender shall (and shall cause any other Payment Recipient that receives funds on its behalf to) promptly (and, in all events, within one Business Day of its knowledge of the occurrence of any of the circumstances described in paragraphs (i), (ii) and (iii) above) notify the

For the avoidance of doubt, the failure to deliver a notice to the Agent pursuant to this Section 11.9(b) shall not have any effect on a Payment Recipient's obligations pursuant to Section 11.9(a) or on whether or not an Erroneous Payment has been made. (c) Each Lender hereby authorizes the Agent, to set off, net and apply any and all amounts at any time owing to such Lender under any Credit Facility Document, or otherwise payable or distributable by the Agent to such Lender under any Credit Facility Document with respect to any payment of principal, interest, fees or other amounts, against any amount that the Agent has demanded to be returned under Section 11.9(a). (d) In the event that an Erroneous Payment (or portion thereof) is not recovered (such unrecovered amount, an "Erroneous Payment Return Deficiency") by the Agent for any reason, after demand therefor in accordance with Section 11.9(a), from any Lender that has received such Erroneous Payment Return Deficiency (and/or from any Payment Recipient who received such Erroneous Payment Return Deficiency on its respective behalf), upon notice from the Agent to such Lender at any time, then effective immediately (with the consideration therefor being acknowledged by the parties hereto): (i) such Lender shall be deemed to have assigned (the "Erroneous Payment Deficiency Assignment") its outstanding Accommodations (but not its Commitments) of the relevant type(s) with respect to which such Erroneous Payment was made in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Agent may specify) on a cashless basis and such amount calculated at par plus any accrued and unpaid interest (with the assignment fee to be waived by the Agent in such instance), and is hereby (together with the Borrowers) deemed to execute and deliver a Lender Assignment Agreement (or, to the extent applicable, an agreement incorporating a Lender Assignment Agreement by reference pursuant to an approved electronic platform as to which the Agent and such parties are participants) with respect to such Erroneous Payment Deficiency Assignment; (ii) the Agent, as the assignee Lender, shall be deemed to acquire the Erroneous Payment Deficiency Assignment; (iii) upon such deemed acquisition, the Agent, as the assignee Lender shall become a Lender, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender shall cease to be a Lender, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, such Lender's obligations under the indemnification provisions of this Agreement and its applicable Commitment which shall survive as to such assigning Lender;

For the avoidance of doubt, no Erroneous Payment Deficiency Assignment will reduce the Commitments of any Lender and such Commitments shall remain available in accordance with the terms of this Agreement. (e) Subject to Sections 11.16, 11.17 and 11.18 (but excluding, in all events, any assignment consent or approval requirements (whether from the Borrowers or otherwise)), the Agent may, in its discretion, sell any Accommodations acquired pursuant to an Erroneous Payment Deficiency Assignment and upon receipt of the proceeds of such sale, the Erroneous Payment Return Deficiency owing by the applicable Lender shall be reduced by the net proceeds of the sale of such Accommodations (or portion thereof), and the Agent, shall retain all other rights, remedies and claims against such Lender (and/or against any Payment Recipient that receives funds on its respective behalf). In addition, an Erroneous Payment Return Deficiency owing by the applicable Lender: (i) shall be reduced by the proceeds of prepayments or repayments of principal and interest, or other distribution in respect of principal and interest, received by the Agent on or with respect to any such Accommodations acquired from such Lender pursuant to an Erroneous Payment Deficiency Assignment (to the extent that any such Accommodations are then owned by the Agent); and (ii) may, in the sole discretion of the Agent, be reduced by any amount specified by the Agent in writing to the applicable Lender from time to time. (f) The parties hereto agree that: (i) irrespective of whether the Agent may be equitably subrogated, in the event that an Erroneous Payment (or portion thereof) is not recovered from any Payment Recipient that has received such Erroneous Payment (or portion thereof) for any reason, the Agent, shall be subrogated to all the rights and interests of such Payment Recipient (and, in the case of any Payment Recipient who has received funds on behalf of a Lender, to the rights and interests of such Lender) under the Credit Facility Documents with respect to such amount (the "Erroneous Payment Subrogation Rights") (provided that the Borrowers' Obligations under the Credit Facility Documents in respect of the Erroneous Payment Subrogation Rights shall not be duplicative of such Obligations in respect of Accommodations that have been assigned to the Agent under an Erroneous Payment Deficiency Assignment); and (ii) an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any Obligations owed by the Borrowers; provided that this Section

(g) To the extent permitted by applicable law, no Payment Recipient shall assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Agent for the return of any Erroneous Payment received, including, without limitation, any defense based on "discharge for value" or any similar doctrine. (h) Each party's obligations, agreements and waivers under this Section shall survive the resignation or replacement of the Agent, any transfer of rights or obligations by, or the replacement of, a Lender, the termination of the Commitments and/or the repayment, satisfaction or discharge of all Obligations (or any portion thereof) under any Credit Facility Document. 11.10 Environmental Indemnity. Each Borrower will protect, indemnify and hold the Agent and the Lenders and all directors, officers, employees and agents of the Agent or the Lenders harmless from and against any and all actual or potential claims, liabilities, damages (including punitive and consequential damages), losses, fines, penalties, sanctions, judgments, awards, costs and expenses whatsoever (including, without limitation, costs and expenses of investigating, denying or defending any of the foregoing and costs and expenses for preparing any necessary environmental assessment report or other such reports) which arise out of or relate in any way to: (a) the presence, use, handling, production, transportation, storage, release, deposit, discharge or disposal of any Hazardous Materials in, on or about any properties or assets owned, operated or occupied by such Borrower and its Subsidiaries, whether by such Borrower, its Subsidiaries or any other Person; (b) any remedial action taken by the Agent or any Lender in connection with any matter referred to in paragraph (a), including without limitation any repair, clean-up, remediation or detoxification of any of such properties or assets and the preparation of any closure or other required plans; and (c) any breach by such Borrower or any of its Subsidiaries of any Environmental Law. The indemnity provisions set forth above in this Section shall not apply in respect of claims occurring by reason of any trustee in bankruptcy having failed to comply with any Law (including any Environmental Law) in respect of any property, and are not intended to indemnify any indemnified party for its own gross negligence or wilful misconduct.

If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder to a Lender from the Original Currency into the Judgment Currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Lender could purchase the Original Currency with the Judgment Currency on the Business Day preceding that on which final judgment is paid or satisfied. The obligations of the Borrowers in respect of any sum due in the Original Currency to the Lender under any of the Credit Facility Documents shall, notwithstanding any judgment in any Judgment Currency, be discharged only to the extent that on the Business Day following receipt by the Lender of any sum adjudged to be so due in such Judgment Currency, the Lender may in accordance with normal banking procedures purchase the Original Currency with such Judgment Currency. If the amount of the Original Currency so purchased is less than the sum originally due to the Lender in the Original Currency, the applicable Borrower shall, as a separate obligation and notwithstanding any such judgment, indemnify the Lender against such loss, and if the amount of the Original Currency so purchased exceeds the sum originally due to the Lender in the Original Currency the Lender agrees to remit such excess to the applicable Borrower. 11.12 Governing Law. This Agreement and the Credit Facility Documents shall be governed by, and construed in accordance with, the laws of the Province of British Columbia and of Canada applicable therein and shall be treated in all respects as British Columbia contracts. 11.13 Consent to Jurisdiction. The Borrowers, the Lenders, the Agent hereby irrevocably submit to the jurisdiction of any British Columbia court sitting in Vancouver, British Columbia, in any action or proceeding arising out of or relating to this Agreement or any other Credit Facility Document, and each of them hereby irrevocably agrees that all claims in respect of any such action or proceeding may be heard and determined in such British Columbia court. Each of them hereby irrevocably waives, to the fullest extent each may effectively do so, the defence of an inconvenient forum to the maintenance of such action or proceeding. Nothing in this Section shall affect the right of any Lender, the Agent to serve legal process in any other manner permitted by Law or the right of any Lender, the Agent to bring any action or proceeding against any Borrower or its property in the courts of other jurisdictions. 11.14 Lenders' Several Liability. The obligations of the Lenders hereunder are several and not joint. No Lender shall be responsible for the failure of any other Lender to make an Advance or perform any other obligation hereunder, and the failure of any Lender to make any Advance or perform any other obligation shall not relieve any other Lender of its obligations hereunder.

- 110 - 1380-6618-2422.9 11.15 Successors and Assigns. This Agreement shall become effective when it has been executed by the Borrowers, the Agent and the Lenders and thereafter shall be binding upon and enure to the benefit of the Borrowers, the Agent, the Lenders and their respective successors and permitted assigns. No Borrower shall have the right to assign its rights or obligations hereunder or any interest herein without the prior consent of the Lenders. 11.16 Assignment. Any Lender may assign all or any part of its Commitment under one or more of the Credit Facilities and its interest in the outstanding Accommodations under such Credit Facility or Credit Facilities to one or more Assignees in respect of an assigned Commitment amount of not less than US$5,000,000 under each Credit Facility for each such Assignee, upon payment by the assigning Lender to the Agent of a fee of US$5,000 for each occurrence. Any such assignment shall be subject to: (a) the approval of the Borrowers (such approval not to be unreasonably withheld or delayed), provided that no such approval of the Borrowers shall be required during the continuance of a Default or an Event of Default, and provided further that the Borrowers shall be deemed to have approved any proposed assignment if the Borrowers fail to either approve or decline to approve such assignment in response to any request for such approval within five Business Days after receipt of such request; (b) the approval of the Agent (such approval not to be unreasonably withheld or delayed); (c) in the case of an assignment by a US Lender, to the approval of the Agent (such approval not to be unreasonably withheld or delayed); and (d) in the case of an assignment in respect of the Revolver Facility, the approval of the WFT Swingline Lender, the WFUS Swingline Lender and the Fronting Lender (each such approval not to be unreasonably withheld or delayed). Such Lender shall deliver to the Borrowers and the Agent (and, in the case of an assignment by a US Lender, the Agent) a Lender Assignment Agreement executed by the Assignee, the Borrowers and the Agent, under which the Assignee assumes the obligations and agrees to be bound by all the terms and conditions of this Agreement, all as if such Assignee had been an original party hereto, and agrees to make Accommodations in respect of the Credit Facilities so assigned through a lending office in Canada, in the case of an assignment by a Canadian Lender or an Term Lender. Upon any such assignment and such assumption of the obligations of the Lender by an Assignee, the assigning Lender and the Borrowers shall be mutually released from their respective obligations hereunder to the extent of such assignment and assumption and shall thenceforth have no liability or obligations to each other to such extent, except in respect of matters which have arisen prior to such assignment. A Lender may, on notice to the Borrowers as to the recipient, deliver a copy of any financial statement or any other information relating to the business, assets or condition (financial or otherwise) of the Borrowers which may be furnished to it under this Agreement or otherwise to any Assignee or any prospective Assignee to the extent reasonably required by such Assignee in connection with its

All such Assignees or prospective Assignees shall agree to maintain the confidential nature of such information. 11.17 Participation. Any Lender may at any time, without the consent of, or notice to, the Borrowers, the Agent or any other Lender, sell participations to any Person (other than a natural Person, a Borrower or any Affiliate of a Borrower) (each, a "Participant") in all or a portion of such Lender's rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or its interest in the outstanding Accommodations); provided that (i) such Lender's obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrowers, the Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement. Any payment by a Participant to a Lender in connection with a sale of a participation shall not be or be deemed to be a repayment by a Borrower or a new Accommodation to a Borrower. Subject to Section 11.18, the Borrowers agree that each Participant shall be entitled to the benefits of Sections 9.6 and 9.7 to the same extent as if the Participant were a Lender and had acquired its interest by assignment pursuant to Section 11.16, provided such Participant: (a) in the case of a participation as a Canadian Lender and/or in the Term Facility: (i) is organized under the laws of Canada (or any province or territory of Canada), is an authorized foreign bank under the Bank Act (Canada), or is otherwise considered or deemed to be resident for income tax or withholding tax purposes in Canada; and (ii) agrees that any contribution to Accommodations to WFT in respect of the Revolver Facility and/or the Term Facility will be made by such Participant through a lending office in Canada; or (b) in the case of a participation as a US Lender, is organized under the laws of the United States (or any state of the United States or the District of Columbia) or is otherwise considered or deemed to be resident for income tax or withholding tax purposes in the United States. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.5 as though it were a Lender, provided such Participant agrees to be subject to Section 11.8 as though it were a Lender. 11.18 Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 9.6 or 9.7 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrowers' prior written consent. In addition:

The Borrowers hereby agree to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. (b) In the event that: (i) any Lender requests Compensation pursuant to Section 9.6 or requires the Borrowers to pay any additional amount to such Lender or any Governmental Authority for the account of any Lender pursuant to Section 9.7; (ii) any Lender's obligations are suspended pursuant to Section 9.1; or (iii) any Lender defaults in its obligation to fund Accommodations hereunder, then a Borrower may, at its sole effort and expense (including any assignment fee payable to the Agent under Section 11.16), upon 10 days' notice to such Lender and the Agent (and the Agent if such Lender is a US Lender), and provided the circumstance giving rise to such Compensation or payment, such suspension or such default, as the case may be, is then continuing, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 11.16), all of such Lender's interests, rights and obligations under this Agreement and the related Credit Facility Documents to an assignee (which may be another Lender) that shall assume such obligations, provided that:

The provisions of this Agreement are intended to be severable. If any provision of this Agreement shall be held invalid or unenforceable in whole or in part in any jurisdiction, such provision shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without in any manner affecting the validity or enforceability thereof in any other jurisdiction or the remaining provisions hereof in any jurisdiction. 11.21 Prior Understandings. This Agreement supersedes all other understandings and agreements, whether written or oral, among the parties hereto relating to the transactions provided for herein. 11.22 Time of Essence. Time shall be of the essence hereof 11.23 Counterparts. This agreement, and all documents to be delivered on or before the Closing Date hereunder, may be executed electronically and in counterparts, each of which shall be deemed an original and which, taken together, shall constitute one and the same instrument, and any executed counterpart may be delivered by facsimile, by transmission of a pdf or scanned copy or by similar means of recorded communication. 11.24 Patriot Act. Each Lender that is subject to the requirements of the Patriot Act hereby notifies the Borrowers and their Subsidiaries that, pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrowers and their Subsidiaries, which information includes the name and address of the Borrowers and their Subsidiaries and other information that will allow such Lender to identify the Borrowers and their Subsidiaries in accordance with the Patriot Act. 11.25 FATCA.

Each such Lender shall, whenever a lapse in time or change in circumstances renders such documentation expired, obsolete or inaccurate in any respect, deliver promptly to the Borrowers and the Agent updated or other appropriate documentation (including any new documentation reasonably requested by the applicable withholding agent) or promptly notify the Borrowers and the Agent of its inability to do so. In addition, any Lender, if reasonably requested by a Borrower or the Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by a Borrower or the Agent as will enable the Borrowers or the Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. (b) Notwithstanding anything to the contrary in Section 11.25(a), the completion, execution and submission of such documentation (other than such documentation set forth in Section 11.25(c)) shall not be required if in the Lender's reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. (c) If a payment made to a Lender under any Credit Facility Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the IRC, as applicable), such Lender shall deliver to the Borrowers and the Agent at the time or times prescribed by law and at such time or times reasonably requested by a Borrower or the Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the IRC) and such additional documentation reasonably requested by a Borrower or the Agent as may be necessary for the Borrowers and the Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender's obligations under FATCA or to determine the amount to deduct and withhold from such payment. 11.26 Acknowledgment Regarding any Supported QFCs. (a) As used in this Section 11.26, the following terms have the following meanings: (i) "BHC Act Affiliate" of a party means an "affiliate" (as such term is defined under, and interpreted in accordance with, 12 U.

(ii) In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a US Special Resolution Regime, Default Rights under the Credit Facility Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the US Special Resolution Regime if the Supported QFC and the Credit Facility Documents were governed by the laws of the United States or a state of the United States. 11.27 Waiver of Jury Trial.
