If an Interest Period would otherwise end on a day which is not a Business Day, such Interest Period shall instead end on the next Business Day in that calendar month (if there is one) or the immediately preceding Business Day (if there is not).

Any determination, decision or election that may be made by the Facility Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 5.8 (Benchmark Replacement Setting), including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Finance Document, except, in each case, as expressly required pursuant to this Section 5.8 (Benchmark Replacement Setting). (d) Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Finance Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate (including the Term SOFR Reference Rate) and either (A) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Facility Agent in its reasonable discretion or (B) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is not or will not be representative, then the Facility Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is not or will not be representative for a Benchmark (including a Benchmark Replacement), then the Facility Agent may modify the definition of “Interest Period” (or any similar or analogous definition) for all Benchmark settings at or after such time to reinstate such previously removed tenor. (e) Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any pending request for a Loan during any Benchmark Unavailability Period.

47 5.9 Market Disruption for Term SOFR.

(a) If this Section 5.10 (Cost of Funds) applies, the rate of interest on the Loan for the relevant Interest Period shall be the percentage rate per annum which is the sum of: (i) the Applicable Margin; and (ii) the rate notified to the Facility Agent by each Lender as soon as practicable and in any event by close of business on the date falling fifteen (15) Business Days after the LIBOR Quotation Day or Periodic Term SOFR Determination Day, as applicable, (or, if earlier, on the date falling three (3) Business Days before the date on which interest is due to be paid in respect of that Interest Period), to be that which expresses as a percentage rate per annum the cost of the relevant Lender of funding an amount equal to its participation in the Loan from whatever source it may reasonably select. (b) If this Section 5.10 (Cost of Funds) applies and the Facility Agent or the Borrower so requires, the Facility Agent and the Borrower shall enter into negotiations (for a period of not more than thirty (30) days) with a view to agreeing a substitute basis for determining the rate of interest. (c) Any alternative basis agreed pursuant to paragraph (b) above shall, with the prior consent of all the Lenders of such Class and the Borrower, be binding on all parties. (d) If this Section 5.10 (Cost of Funds) applies but any Lender does not supply a quotation by the time specified in paragraph (a)(ii) above, the rate of interest shall be calculated on the basis of the quotations of the remaining Lenders of such Class. 5.11 Break Costs. (a) The Borrower shall indemnify, compensate and reimburse each Lender for all Break Costs which such Lender may sustain: (i) if the Borrower withdraws or reduces the amount specified for a Utilization in a

48 Utilization Request or fails to satisfy any of the conditions precedent specified in Article 11 (Conditions Precedent) after delivering a Utilization Request (unless waived by the Lenders pursuant to Section 22.4 (Amendment and Waiver); provided, that if the Borrower withdraws or reduces the amount specified for any Utilization Request, then the Applicable Margin shall be included in the calculation of Break Costs but in all other cases (including clauses (ii) and (iii) of this Section 5.11 (Break Costs), the Applicable Margin should not be included in the calculation of Break Costs). (ii) if the Borrower fails to pay any amount of principal of the Loans due and payable under a Finance Document on its due date; or (iii) if any repayment or prepayment (whether mandatory or voluntary) of its Loan occurs on a date that is not the last day of the current Interest Period therefor for the Loan, in accordance with Article 4 (Repayment, Prepayment and Cancellation) of this Agreement. (b) Each Lender shall furnish to the Borrower a certificate setting forth in reasonable detail the basis and amount of each request by such Lender for compensation under this Section 5.11 (Break Costs), which certificate shall be conclusive and binding on the Borrower in the absence of manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within three (3) Business Days after receipt thereof. 5.12 Fees. (a) Covered Loan Commitment Fee. The Borrower shall pay to the Facility Agent (for the account of each Lender) a Covered Loan Commitment Fee at a rate per annum equal to 0.40% of the daily Unused Commitment of Covered Loans of such Covered Lender, for the period from and including the Original Effective Date to but excluding the last day of the Covered Loan Commitment Period. Accrued Covered Loan Commitment Fees shall be payable quarterly in arrears starting from the Original Effective Date, or, in the case of the last installment of the Covered Loan Commitment Fee payable hereunder, on the last day of the Covered Loan Commitment Period. No other commitment fees will be payable to the Facility Agent or the Covered Lenders on account of the Covered Loans. Notwithstanding the foregoing, no Covered Lender shall be entitled to receive any commitment fee for any period during which such Covered Lender is a Defaulting Lender (and the Borrower shall not be required to pay any commitment fee that otherwise would have been required to be paid to that Defaulting Lender). (b) Commercial Loan Commitment Fee. The Borrower shall pay to the Facility Agent (for the account of each Lender) a Commercial Loan Commitment Fee at a rate per annum equal to 1.00% of the daily Unused Commitment of Commercial Loans of such Commercial Lender, for the period from and including the Original Effective Date to but excluding the last day of the Commercial Loan Commitment Period. Accrued Commercial Loan Commitment Fees shall be payable quarterly in arrears starting from the Original Effective Date, in the case of the last installment of the Commercial Loan Commitment Fee payable hereunder, on the last day of the Commercial Loan Commitment Period. No

49 other commitment fees will be payable to the Facility Agent or the Commercial Lenders on account of the Commercial Loans. Notwithstanding the foregoing, no Commercial Lender shall be entitled to receive any commitment fee for any period during which such Commercial Lender is a Defaulting Lender (and the Borrower shall not be required to pay any commitment fee that otherwise would have been required to be paid to that Defaulting Lender). (c) OeKB Guarantee Premium. Subject to the issuance of the OeKB Guarantee, the Borrower shall pay the OeKB Guarantee Premium in the amounts, at such time and manner specified in the OeKB Guarantee, which payment shall be made with the proceeds of the Premium Loans after disbursement thereof in accordance with the terms of this Agreement. (d) Other Fees. The Borrower shall pay such other fees in the amounts and manner agreed between any Finance Party and the Borrower in any Fee Letter. Article 6 TAXES (a) Defined Terms. For purposes of this Article 6 (Taxes), the term “Applicable Law” includes FATCA. (b) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower under any Finance Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of the Borrower) requires the deduction or withholding of any Tax from any such payment by the Borrower, then the Borrower shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Body in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Article 6 (Taxes)), the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding for Indemnified Taxes been made. (c) Payment of Other Taxes by Borrower. The Borrower shall timely pay to the relevant Governmental Body in accordance with Applicable Law, or at the option of the Facility Agent timely reimburse it for the payment of, any Other Taxes. (d) Indemnification by Borrower. The Borrower shall indemnify each Recipient, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Article 6 (Taxes)) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, other than any penalties and interest resulting from the willful misconduct or fraud of the Facility Agent or such Lender, and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were

50 correctly or legally imposed or asserted by the relevant Governmental Body. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Facility Agent), or by the Facility Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. (e) Indemnification by the Lenders. Each Lender shall severally indemnify the Facility Agent within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Facility Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 13.1(j) (Assignment by Lenders) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Facility Agent in connection with any Finance Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Body. A certificate as to the amount of such payment or liability delivered to any Lender by the Facility Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Facility Agent to set off and apply any and all amounts at any time owing to such Lender under any Finance Document or otherwise payable by the Facility Agent to the Lender from any other source against any amount due to the Facility Agent under this paragraph (e). (f) Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Body pursuant to this Article 6 (Taxes), the Borrower shall deliver to the Facility Agent the original or a certified copy of a receipt issued by such Governmental Body evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Facility Agent. (g) Status of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Finance Document shall deliver to the Borrower and the Facility Agent, at the time or times reasonably requested by the Borrower or the Facility Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Facility Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Facility Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Facility Agent as will enable the Borrower or the Facility Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in paragraphs (g)(ii)(A), (ii)(B) and (ii)(D) of this Article 6 (Taxes)) 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. (ii) Without limiting the generality of the foregoing,

51 (A) any Lender that is a U.S. Person shall deliver to the Borrower and the Facility Agent on or about the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Facility Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding Tax; (B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Facility Agent (in such number of copies as shall be requested by the recipient) on or about the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Facility Agent), whichever of the following is applicable: (1) in the case of a Foreign Lender claiming the benefits of an income Tax treaty to which the United States of America is a party (x) with respect to payments of interest under any Finance Document, executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such Tax treaty and (y) with respect to any other applicable payments under any Finance Document, IRS Form W-8BEN or IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such Tax treaty; (2) executed copies of IRS Form W-8ECI; (3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit A-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 871(h)(3)(B) of the Code, or a “controlled foreign corporation” related to the Borrower as described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E; or (4) to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, IRS Form W-8BEN-E, a U.S. Tax Compliance Certificate substantially in the form of Exhibit A-2 or Exhibit A-3, IRS Form W-9, and other certification documents from each beneficial owner, as applicable; provided, that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender

52 may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit A-4 on behalf of each such direct and indirect partner; (C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Facility Agent (in such number of copies as shall be requested by the recipient) on or about the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Facility Agent), executed copies of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrower or the Facility Agent to determine the withholding or deduction required to be made; and (D) each Lender shall deliver to the Borrower and the Facility Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Facility Agent such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Facility Agent as may be necessary for the Borrower and the Facility 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, if any, to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Facility Agent in writing of its legal inability to do so. (h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes (including any tax credit in lieu of a refund) as to which it has been indemnified pursuant to this Article 6 (Taxes) (including by the payment of additional amounts pursuant to this Article 6 (Taxes)), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Article 6 (Taxes) with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Body with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Body) in the event that such indemnified party is required to repay such refund to such Governmental Body. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had

53 not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph (h) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person. (i) Survival. Each party’s obligations under this Article 6 (Taxes) shall survive the resignation or replacement of the Facility Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Finance Document. Article 7 OTHER PROVISIONS RELATING TO THE LOANS 7.1 Payments Generally. (a) The Borrower shall make each payment required to be made by it under this Agreement on the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. (b) Any amounts received after close of business on any date may, in the discretion of the Facility Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. (c) All such payments shall be made to the Facility Agent at the Facility Agent’s Account, except that payments pursuant to Sections 7.3 (Change in Circumstances), 7.4 (Payment of Out-of-Pocket Costs and Expenses) and 7.5 (Indemnities) shall be made directly to the Persons entitled thereto. (d) The Facility Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. (e) All payments under or in connection with this Agreement shall be made in U.S. Dollars unless otherwise specified. 7.2 Illegality. If any Applicable Law comes into force after the Original Effective Date, or if any change in any existing Applicable Law or in the interpretation or application thereof by any court of competent jurisdiction or Governmental Body now or hereafter makes it unlawful for a Lender to have advanced or acquired an interest in any of the Loans or to fund or otherwise maintain any of the Loans or to give effect to its obligations in respect thereof, such Lender may, by written notice thereof to the Borrower, declare its obligations under this Agreement to be terminated, and the Borrower shall immediately cancel any available Commitments of such Lender and prepay, within the time required by such law and if not so required by any time, promptly after such notice, the Loans and any other amounts owing under this Agreement (including accrued and unpaid interest) as may be applicable to, but not including, the date of such payment. If any such event shall, in the

54 opinion of such Lender, only affect part of its obligations under this Agreement, the remainder of this Agreement shall be unaffected and the obligations of the Borrower under the Finance Documents shall continue. Each Lender agrees to use commercially reasonable efforts to designate a different lending office if such designation will avoid the need for such notice and will not, in the judgment of such Lender, acting reasonably, otherwise be materially disadvantageous (including among others, reduction in rate of return) to such Lender. The Borrower hereby agrees to pay all reasonable out-of-pocket costs and expenses Incurred by any Lender in connection with any such designation or assignment. 7.3 Change in Circumstances. (a) If the introduction of or any change in any Applicable Law relating to a Lender or any change in the interpretation or application thereof by any Governmental Body or compliance by a Lender with any request or direction of any Governmental Body: (i) subjects such Lender to any Taxes (other than Indemnified Taxes, Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; (ii) imposes, modifies or deems applicable any reserve, liquidity, cash margin, capital, special deposit, deposit insurance or assessment, or any other regulatory or similar requirement or any additional or increased cost against assets held by, or deposits in or for the account of, or loans by, or any other acquisition of funds for loans by, such Lender or any direct or indirect holding company of such Lender; (iii) imposes on such Lender or any direct or indirect holding company of such Lender or requires there to be maintained by such Lender any capital adequacy, liquidity or additional liquidity capital requirement (including, without limitation, a requirement which affects such Lender’s or such holding company’s allocation of capital resources to its obligations) in respect of such Lender’s obligations hereunder; or (iv) imposes on such Lender any other condition or requirement with respect to this Agreement (provided, however, that this Section 7.3(a)(iv) (Change in Circumstances) shall not apply with respect to any Taxes, but shall not limit any rights or obligations arising under Section 7.3(a)(i) (Change in Circumstances)); (b) and subject to paragraph (c) below, such occurrence has the effect of: (i) increasing the cost to such Lender of agreeing to make or making, maintaining or funding the Loan or any portion thereof; (ii) reducing the amount of the Obligations (including reduction in the rate of return) owing to such Lender; (iii) directly or indirectly reducing the effective return to such Lender under this Agreement or on its overall capital as a result of entering into this Agreement or as

55 a result of any of the transactions or obligations contemplated by this Agreement; or (iv) causing such Lender to make any payment or to forgo any interest, fees or other return on or calculated by reference to any sum received or receivable by such Lender under this Agreement; then, upon written request of such Lender, the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs Incurred or reduction suffered. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender and delivered to the Borrower, shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof. (c) For purposes of the foregoing, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, regulations, guidelines, requirements and directives thereunder, issued in connection therewith or in implementation thereof and (ii) all requests, rules, regulations, guidelines or directives whether concerning capital adequacy or liquidity promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States of America or foreign regulatory authorities, in each case pursuant to Basel III, shall, in each case, be deemed a “change in Applicable Law” regardless of the date enacted, adopted, applied or issued. 7.4 Payment of Out-of-Pocket Costs and Expenses. The Borrower shall pay to the Facility Agent and the Lenders on demand all reasonable out-of- pocket costs and expenses (including, without limitation, all reasonable fees, properly invoiced and documented out-of-pocket expenses and disbursements of outside legal counsel) (other than in the case of Section 7.4(d) (Payment of Out-of-Pocket Costs and Expenses) below, in which case the Borrower shall pay the Facility Agent and the Lenders on demand all out-of-pocket costs and expenses) of the Agents and the Lenders and their agents, counsel, and any receiver or receiver- manager appointed by them or by a court in connection with this Agreement and the other Finance Documents and the OeKB Guarantee, including, without limitation: (a) the preparation, negotiation, and completion of the Finance Documents and the OeKB Guarantee, or any actual or proposed amendment or modification thereof or any waiver thereunder and all instruments supplemental or ancillary thereto; (b) fees and expenses of the Lenders Incurred as part of the Lenders’ due diligence; (c) obtaining advice as any Agent’s or the Lenders’ rights and responsibilities under this Agreement or the other Finance Documents or the OeKB Guarantee; (d) the defense, establishment, protection or enforcement of any of the rights or remedies of the Lenders under this Agreement or any of the other Finance Documents or the OeKB Guarantee, including all out-of-pocket costs and expenses of establishing the validity and enforceability of, or of collection of amounts owing under, this Agreement; and

56 (e) translation costs, including, but not limited to, the translation of the OeKB Guarantee from German into English. 7.5 Indemnities. (a) The Borrower shall indemnify and hold harmless each Agent, each Lender and the OeKB Guarantor and their Affiliates, officers, directors and employees (each, an “Indemnified Party”) from all Claims (including the properly invoiced and documented fees, out-of- pocket expenses and disbursements of outside legal counsel to the Lenders and the OeKB Guarantor in each applicable jurisdiction), which may be Incurred by any Indemnified Party as a consequence of or in respect of: (i) default by the Borrower in the payment when due of any Obligation or any other Default or Event of Default hereunder which is continuing; (ii) the entering into by the relevant Agents and the Lenders of this Agreement and any amendment, waiver or consent relating hereto, and the performance by such Agents and the Lenders of their obligations under this Agreement; (iii) failure of the Borrower to comply with any Applicable Law, including, without limitation, any Environmental Law or applicable Anti-Corruption Laws or Sanctions, with respect to the Project Upgrades; (iv) any Environmental Matter and Environmental Claim with respect to the Project Upgrades; (v) the application by the Borrower of the proceeds of the Loan; or (vi) any material Claim arising in connection with the Project Upgrades, except for any such Claim that a final and non-appealable court of competent jurisdiction determined arose primarily on account of the relevant Indemnified Party’s gross negligence or willful misconduct. (b) In connection with any Claim described in Section 7.5(a) (Indemnities) above, the applicable Indemnified Party shall deliver a certificate of an officer of the Facility Agent or the applicable Lender as to: (i) any such Claim; and (ii) containing reasonable details of the calculation (which calculation shall be, absent manifest error, prima facie evidence of the calculation of the amount of such Claim) and any supporting documentation, including but not limited to invoices and receipts.

The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Facility Agent (in its capacity as Facility Agent) shall have no responsibility for maintaining a Participant Register. (k) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank or any other central bank; provided, that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. (l) In connection with any assignment, participation or pledge made pursuant to this Section 13.1 (Assignment by Lenders), the Borrower agrees to enter into such documents as may reasonably be required by a Lender to evidence such assignment, participation or pledge. 13.2 Assignment by Borrower.

(e) Without prejudice to any provision of any Finance Document or the OeKB Guarantee, as applicable, excluding or limiting an Administrative Party’s liability, any liability of an Administrative Party arising under or in connection with any Finance Document, the OeKB Guarantee, as applicable, shall be limited to the amount of actual loss which has been finally judicially determined to have been suffered (as determined by reference to the date of default of such Administrative Party or, if later, the date on which the loss arises as a result of such default) but without reference to any special conditions or circumstances known to such Administrative Party at any time which increase the amount of such loss.

Any successor and each of the other Administrative Parties shall have the same rights and obligations amongst themselves as they would have had if such successor had been an original party. (g) Pursuant to the terms of the OeKB Guarantee, the parties hereto acknowledge that any successor ECA Agent shall be required to act as “Guarantee Holder” under the OeKB Guarantee.

(b) The retiring ECA Agent shall (at its own cost if it is an Impaired Agent and otherwise at the expense of the Covered Lenders) make available to the successor ECA Agent such documents and records and provide such assistance as the successor ECA Agent may reasonably request for the purposes of performing its functions as ECA Agent under the Finance Documents.

101 14.19 Agent’s Confidentiality. (a) In acting as an agent for the Finance Parties, each Administrative Party shall be regarded as acting through its agency division which shall be treated as a separate entity from any other of its divisions and departments. (b) If information is received by another division or department of any Administrative Party, it may be treated as confidential to such division or department and such Administrative Party shall not be deemed to have notice of it. 14.20 Consent of the OeKB Guarantor.

The Facility Agent shall notify the Covered Lenders that such consent has been obtained or denied, as the case may be. (b) Notwithstanding the foregoing or anything else to the contrary in this Agreement or the Finance Documents, the parties hereto acknowledge and agree that, pursuant to the terms of the OeKB Guarantee, the OeKB Guarantor shall have sole consent and approval rights over any waivers, amendments, supplements or modifications of or under this Agreement and shall, in its sole discretion, direct the voting of the Covered Lenders through the ECA Agent. 14.21 Credit Appraisal by the Covered Lenders. Without affecting the responsibility of the Borrower for information supplied by it or on its behalf in connection with any Finance Document or the OeKB Guarantee, as applicable, each Covered Lender confirms to the Administrative Parties that it has been, and shall continue to be, solely responsible for making its own independent appraisal and investigation of all risks arising under or in connection with any Finance Document and the OeKB Guarantee, including but not limited to: (a) the financial condition, creditworthiness, status and nature of the Borrower; (b) the legality, validity, effectiveness, adequacy or enforceability of any Finance Document, the OeKB Guarantee and any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Finance Document; (c) whether such Covered Lender has recourse, and the nature and extent of such recourse, against any Finance Party or any of its respective assets under or in connection with any Finance Document, the OeKB Guarantee, the transactions contemplated by the Finance Documents, the OeKB Guarantee, or any other agreement, arrangement or document entered into made or executed in anticipation of, under or in connection with any Finance Document, the OeKB Guarantee, as applicable; and

102 (d) the adequacy, accuracy and completeness of any reports and any other information provided by any Administrative Party, by any Finance Party or by any other person under or in connection with any Finance Document, the OeKB Guarantee, the transactions contemplated by the Finance Documents and OeKB Guarantee, or any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Finance Document and the OeKB Guarantee. 14.22 Deduction from Amounts Payable by Administrative Parties. If any Finance Party owes an amount to any Administrative Party under the Finance Documents or the OeKB Guarantee, as applicable, such Administrative Party may, after giving notice to such Finance Party, deduct an amount not exceeding such amount from any payment to such Finance Party which such Administrative Party would otherwise be obligated to make under the Finance Documents or the OeKB Guarantee, as applicable, and apply the amount deducted in or towards satisfaction of the amount owed. For the purposes of the Finance Document or the OeKB Guarantee, as applicable, such Finance Party shall be regarded as having received the amount so deducted. 14.23 Notice Period. Where a Finance Document or the OeKB Guarantee, as applicable, specifies a minimum period of notice to be given to any Administrative Party, such Administrative Party may, at its discretion, accept a shorter notice period. 14.24 Payments.

(b) Following an Event of Default that is continuing, provided the Facility Agent has declared all Obligations immediately due and payable, all payments shall be made to the Facility Agent for distribution to the Lenders in accordance with this Agreement, such that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the Applicable Percentage of the Covered Loans or Commercial Loans, as the case may be, owing to them; provided, that the provisions of this Section 14.24 (Payments) shall not be construed to apply to: (i) any payment made in respect of an obligation that is secured by a Permitted Lien or that is otherwise entitled to priority over the Borrower’s obligations under or in connection with the Finance Documents or the OeKB Guarantee, as applicable; or (ii) any payment to which such Lender is entitled in its capacity as a party to any Finance Document or the OeKB Guarantee, as applicable. 14.25 Agents as Lender. With respect to its Commitment and the Loans made by it, any Person serving as an Agent hereunder shall have the same rights and powers under the Finance Documents as any other Lender

103 and may exercise the same as though it were not such Agent. The term “Lender” or “Finance Party”, when used with respect to each Agent, shall unless otherwise expressly indicated, include such Agent in its individual capacity. Each Agent and its Affiliates may accept deposits from, lend money to, act as trustee under, act as financial advisor or in any other advisory capacity for and generally engage in any kind of business with, any Person as if such Agent were not the applicable Agent hereunder, without any duty to account therefor to the Lenders or Finance Parties. Article 15 CONDUCT OF BUSINESS BY THE FINANCE PARTIES 15.1 Conduct of Business by the Finance Parties. No provision of any Finance Document or the OeKB Guarantee, as applicable, will: (a) interfere with the right of any Finance Party to arrange its affairs (Tax or otherwise) in whatever manner it deems appropriate; (b) obligate any Finance Party to investigate or claim any credit, relief, remission or repayment available to it or the extent, order and manner of any claim; or (c) obligate any Finance Party to disclose any information relating to its affairs (Tax or otherwise) or any computations in respect of Tax. Article 16 PAYMENT MECHANICS 16.1 Payments to the Agents. (a) On each date on which the Borrower or a Lender is required to make a payment under a Finance Document (including as relates to any payments to be made in respect of the OeKB Guarantee), the Borrower or such Lender shall make the same available to the Facility Agent or (in the case of any disbursement or payment expressed to be made or payable under the terms of any Finance Document) to the relevant Agent, for value on the due date at the time and in U.S. Dollars. (b) Payment shall be made to such account as the Facility Agent specifies. 16.2 Distributions by the Agents. Each payment received by an Agent under the Finance Documents or the OeKB Guarantee, as applicable, for another Finance Party shall, subject to Section 16.3 (Distributions to the Borrower) and Section 16.4 (Clawback), be made available by that Agent as soon as practicable after receipt to the Finance Party entitled to receive payment in accordance with the Finance Documents or the OeKB Guarantee, and: (a) in the case of payment for the Borrower, to the account identified in writing by the Borrower to an Agent;

104 (b) in the case of payment for a Lender, for the account of its lending office; and (c) in the case of payment for any other Finance Party (other than the Borrower or a Lender), to such account with a bank in New York City as that Finance Party may notify to the Facility Agent by not less than five (5) Business Days’ prior notice. 16.3 Distributions to the Borrower. Each Agent may (with the consent of the Borrower or in accordance with Article 17 (Set-Off)) apply any amount received by it for the Borrower in or towards payment (as soon as practicable after receipt) of any amount due from the Borrower under the Finance Documents. For this purpose, the relevant Agent may apply the received sum in or towards the purchase of any amount of any currency to be paid. 16.4 Clawback. (a) Where a sum is to be paid to an Agent under the Finance Documents or the OeKB Guarantee, as applicable, for another Finance Party, such Agent is not obligated to pay that sum to that other Finance Party (or to enter into or perform any related exchange contract) until it has been able to establish to its satisfaction such it has actually received that sum. (b) If an Agent pays an amount to another Finance Party and it proves to be the case that such Agent has not actually received such amount, then the Finance Party to whom such amount (or the proceeds of any related exchange contract) was paid by such Agent shall on demand refund such amount to such Agent. 16.5 No Set-Off by the Borrower. All payments to be made by the Borrower under the Finance Documents will be calculated and be made without (and free and clear of any deduction for) set-off or counterclaim, it being understood that deduction for withholding Taxes is addressed by Article 6 (Taxes). 16.6 Business Days. (a) Any payment which is due to be made on a day that is not a Business Day will be made on the next Business Day in the same calendar month (if there is one) or the preceding Business Day (if there is not). If the Final Maturity Date is not a Business Day, any payment due on the Final Maturity Date shall be made on the next Business Day in the same calendar month (if there is one) or the preceding Business Day (if there is not). (b) During any extension of the due date for payment of any principal or Unpaid Sum approved by the Finance Parties under a Finance Document and the OeKB Guarantee, interest is payable on the principal or Unpaid Sum at the rate payable on the original due date. 16.7 Currency of Account.

(b) If a change in any currency of a country occurs (including where there is more than one currency or currency unit recognized at the same time as the lawful currency of a country), the Finance Documents will, to the extent the Facility Agent (acting reasonably and after consultation with the Borrower) specifies to be necessary, be amended to comply with any generally accepted conventions and market practice in the relevant interbank market and otherwise reflect the change in currency. Article 17 SET-OFF A Finance Party may set off any matured obligation due from the Borrower under the Finance Documents and the OeKB Guarantee (to the extent beneficially owned by that Finance Party) against any matured obligation owed by that Finance Party to the Borrower, regardless of the place of payment, booking branch or currency of either obligation. If the obligations are in different currencies, the Finance Party may convert either obligation at a market rate of exchange in its usual course of business for the purpose of the set-off. Article 18 BAIL-IN PROVISIONS Notwithstanding anything to the contrary in any Finance Document, the OeKB Guarantee, or in any other agreement, arrangement or understanding among any such Finance Parties, each Finance Party hereto acknowledges that any liability of any Affected Financial Institution arising under any Finance Document, to the extent such liability is unsecured, may be subject to the write-down and conversion powers of the applicable Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

113 (i) an extension of the date of payment of any amount to a Lender under the Finance Documents; (ii) an increase in, or an extension of, a Commitment or the Total Commitments; or (iii) any other amount or provision that requires the consent of the OeKB Guarantor in accordance with the OeKB General Terms and Conditions. 22.5 English Language.

Whether before or after the happening of an Event of Default, the Borrower shall at its own expense do, make, execute or deliver, or cause to be done, made, executed or delivered, all such further acts, things, agreements, documents and instruments in connection with this Agreement, the other Finance Documents or the OeKB Guarantee as the Facility Agent may reasonably request from time to time for the purpose of giving effect to the terms of this Agreement, the other Finance Documents or the OeKB Guarantee, all promptly upon the request of the Facility Agent. 22.7 Judgment Currency. If for the purpose of obtaining or enforcing judgment in any court it is necessary to convert a sum due hereunder or under any other Finance Document in U.S. Dollars into another currency (the “Judgment Currency”), the rate of exchange which shall be applied shall be that at which in accordance with normal banking procedures a Finance Party, as applicable, could purchase such U.S. Dollars in the United States of America with the Judgment Currency on the Business Day next preceding the day on which such judgment is rendered. The obligation of the Borrower in respect of any such sum due from it to such Finance Party hereunder or under any other Finance Document (an “Entitled Person”) shall, notwithstanding the rate of exchange actually applied in rendering such judgment, be discharged only to the extent that on the Business Day following the receipt by such Entitled Person of any sum adjudged to be due hereunder or under any other Finance Document in the Judgment Currency, such Entitled Person may in accordance with normal banking procedures purchase and transfer U.S. Dollars to the United States of America with the amount of the Judgment Currency so adjudged to be due; and the Borrower hereby, as a separate obligation and notwithstanding any such judgment, agrees to indemnify such Entitled Person on demand, in U.S. Dollars, for the amount (if any) by which the sum originally due to such Entitled

114 Person in U.S. Dollars hereunder or under any other Finance Document exceeds the amount of the U.S. Dollars so purchased and transferred. 22.8 Remedies Cumulative. Subject to Applicable Law, no failure or delay on the part of any Finance Party in exercising any right, power or privilege hereunder or under any other Finance Document or the OeKB Guarantee and no course of dealing between the Borrower or any its Affiliates, on the one hand and any Finance Party, on the other hand, shall impair any such right, power or privilege or operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Finance Document or the OeKB Guarantee preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights, powers and remedies herein or in any other Finance Document or the OeKB Guarantee expressly provided are cumulative and not exclusive of any rights, powers or remedies which any party thereto would otherwise have. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of any Finance Party to any other or further action in any circumstances without notice or demand. 22.9 Entire Agreement. This Agreement, the other Finance Documents and the OeKB Guarantee constitute the entire agreement between the parties pertaining to the subject matter described herein and therein. There are no warranties, conditions or representations (including any that may be implied by statute) and there are no agreements in connection with such subject matter except as specifically set forth or referred to in this Agreement, the other Finance Documents and the OeKB Guarantee. No reliance is placed on any warranty, representation, opinion, advice or assertion of fact made either prior to, contemporaneously with, or after the entering into of this Agreement, the other Finance Documents or the OeKB Guarantee, or any amendment or supplement thereto, by any party to this Agreement or any of the other Finance Documents or its directors, officers, partners, employees or agents, where applicable, to any other party to this Agreement or any of the other Finance Documents or its directors, officers, partners, employees or agents, where applicable, except to the extent that the same has been reduced to writing and included as a term of this Agreement or any of the other Finance Documents or the OeKB Guarantee. 22.10 Governing Law; Jurisdiction.
