amount equal to the Maximum Available Commitment at such time, and shall be used to fund the Class A Cash Collateral Account in accordance with said Section 3.5(d) and Section 3.5(f) of the Intercreditor Agreement. 

(c)    A Downgrade Advance shall be made in a single Borrowing upon the occurrence of a Downgrade Event (as provided for
in Section 3.5(c) of the Intercreditor Agreement), unless (i) a Replacement Liquidity Facility to replace this Agreement shall have been previously delivered to the Borrower within thirty-five (35) days after the Downgrade Event or
(ii) the relevant Rating Agency shall have provided confirmation within thirty (30) days after the Downgrade Event that such Downgrade Event will not result in a downgrading, withdrawal or suspension by such Rating Agency of the rating
then in effect for the related Class of Certificates, in each case of clause (i) and (ii), in accordance with said Section 3.5(c), by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially
the form of Annex III attached hereto, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used to fund the Class A Cash Collateral Account in accordance with
said Section 3.5(c) and Section 3.5(f) of the Intercreditor Agreement. Upon the occurrence of a Downgrade Event, the Liquidity Provider shall promptly deliver notice thereof to the Borrower, the Class A Trustee and United.

 [Revolving Credit Agreement (2019-2A)] 

 

 (d)    A Final Advance shall be made in a single Borrowing upon the
receipt by the Borrower of a Termination Notice from the Liquidity Provider pursuant to Section 6.01 hereof by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex IV attached
hereto, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used to fund the Class A Cash Collateral Account (in accordance with Sections 3.5(f) and 3.5(i) of
the Intercreditor Agreement). 
 (e)    Each Borrowing shall be made on notice in writing (a “Notice of
Borrowing”) in substantially the form required by Section 2.02(a), 2.02(b), 2.02(c), 2.02(d) or 2.02(g), as the case may be, given by the Borrower to the Liquidity Provider. If a Notice of Borrowing is delivered by the Borrower in
respect of any Borrowing no later than 1:00 p.m. (New York City time) on a Business Day, upon satisfaction of the conditions precedent set forth in Section 4.02 with respect to a requested Borrowing, the Liquidity Provider shall make
available to the Borrower, in accordance with its payment instructions, the amount of such Borrowing in U.S. dollars and immediately available funds, before 4:00 p.m. (New York City time) on such Business Day. If a Notice of Borrowing is
delivered by the Borrower in respect of any Borrowing on a day that is not a Business Day or after 1:00 p.m. (New York City time) on a Business Day, upon satisfaction of the conditions precedent set forth in Section 4.02 with respect to a
requested Borrowing, the Liquidity Provider shall make available to the Borrower, in accordance with its payment instructions, the amount of such Borrowing in U.S. dollars and in immediately available funds, before 12:00 Noon (New York City time) on
the first Business Day next following the day of receipt of such Notice of Borrowing. Payments of proceeds of a Borrowing shall be made by wire transfer of immediately available funds to the Borrower in accordance with such wire transfer
instructions as the Borrower shall furnish from time to time to the Liquidity Provider for such purpose. Each Notice of Borrowing shall be irrevocable and binding on the Borrower. Each Notice of Borrowing shall be effective upon receipt of a copy
thereof by the Liquidity Provider at the address specified pursuant to Section 7.02. 
 (f)    Upon the making of
any Advance requested pursuant to a Notice of Borrowing, in accordance with the Borrower’s payment instructions, the Liquidity Provider shall be fully discharged of its obligation hereunder with respect to such Notice of Borrowing, and the
Liquidity Provider shall not thereafter be obligated to make any further Advances hereunder in respect of such Notice of Borrowing to the Borrower or to any other Person. If the Liquidity Provider makes an Advance requested pursuant to a Notice of
Borrowing before 12:00 Noon (New York City time) on the second Business Day after the date of payment specified in Section 2.02(e), the Liquidity Provider shall have fully discharged its obligations hereunder with respect to such Advance and an
event of default shall not have occurred hereunder. Following the making of any Advance pursuant to Section 2.02(b), (c), (d) or (g) hereof to fund the Class A Cash Collateral Account, the Liquidity Provider shall have no
interest in or rights to the Class A Cash Collateral Account, the funds constituting such Advance or any other amounts from time to time on deposit in the Class A Cash Collateral Account; provided that the foregoing shall not affect
or impair the obligations of the Subordination Agent to make the distributions contemplated by Section 3.5(e) or (f) of the Intercreditor Agreement, and provided, further, that the foregoing shall not affect or impair the rights of
the Liquidity Provider to provide written instructions with respect to the investment and reinvestment of amounts in the Class A Cash Collateral Account to the extent provided in Section 2.2(b) of the Intercreditor Agreement. By

  
 10 

 [Revolving Credit Agreement (2019-2A)] 

 

 
paying to the Borrower proceeds of Advances requested by the Borrower in accordance with the provisions of this Agreement, the Liquidity Provider makes no representation as to, and assumes no
responsibility for, the correctness or sufficiency for any purpose of the amount of the Advances so made and requested. 

(g)    A Special Termination Advance shall be made in a single Borrowing upon the receipt by the Borrower of a Special
Termination Notice from the Liquidity Provider pursuant to Section 6.02, by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex VII, signed by a Responsible Officer of the
Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used to fund the Class A Cash Collateral Account (in accordance with Section 3.5(f) and Section 3.5(m) of the Intercreditor Agreement). 

Section 2.03    Fees. The Borrower agrees to pay to the Liquidity Provider the fees set forth in the Fee
Letter applicable to this Agreement. 
 Section 2.04    Reductions or Termination of the Maximum Commitment.

 (a)    Automatic Reduction. Promptly following each date on which the Required Amount is reduced as a result of
a reduction in the Pool Balance of the Class A Certificates or otherwise, the Maximum Commitment shall automatically be reduced to an amount equal to such reduced Required Amount (as calculated by the Borrower); provided that on (or, as
applicable, immediately following) the first Regular Distribution Date, the Maximum Commitment shall automatically be reduced to the then Required Amount. The Borrower shall give notice of any such automatic reduction of the Maximum Commitment to
the Liquidity Provider within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not affect such automatic reduction of the Maximum Commitment. 

(b)    Termination. Upon the making of any Provider Advance or Special Termination Advance or the making of or
conversion to a Final Advance hereunder or the occurrence of the Termination Date, the obligation of the Liquidity Provider to make further Advances hereunder shall automatically and irrevocably terminate, and the Borrower shall not be entitled to
request any further Borrowing hereunder, except in the case of a Downgrade Advance, as provided in Section 2.06(d). 

Section 2.05    Repayments of Interest Advances, the Special Termination Advance or the Final Advance. Subject
to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees, without notice of an Advance or demand for repayment from the Liquidity Provider (which notice and demand are hereby waived by the Borrower), to pay, or to cause to be paid, to
the Liquidity Provider on each date on which the Liquidity Provider shall make an Interest Advance, the Special Termination Advance or the Final Advance, an amount equal to (a) the amount of such Advance (any such Advance, until repaid, is
referred to herein as an “Unpaid Advance”) (if multiple Interest Advances are outstanding any such repayment to be applied in the order in which such Interest Advances have been made, starting with the earliest), plus
(b) interest on the amount of each such Unpaid Advance as provided in Section 3.07 hereof; provided that if (i) the Liquidity Provider shall make a Provider Advance at any time after making one or more Interest Advances which
shall not have been repaid in accordance with this Section 2.05 or (ii) this 

  
 11 

 [Revolving Credit Agreement (2019-2A)] 

 

 
Liquidity Facility shall become a Downgraded Facility or Non-Extended Facility at any time when unreimbursed Interest Advances have reduced the Maximum
Available Commitment to zero, then such Interest Advances shall cease to constitute Unpaid Advances and shall be deemed to have been changed into an Applied Downgrade Advance or an Applied Non-Extension
Advance, as the case may be, for all purposes of this Agreement (including, without limitation, for the purpose of determining when such Interest Advance is required to be repaid to the Liquidity Provider in accordance with Section 2.06 and for
the purposes of Section 2.06(b)); provided, further, that amounts in respect of a Special Termination Advance withdrawn from the Class A Cash Collateral Account for the purpose of paying interest on the Class A
Certificates in accordance with Section 3.5(f) of the Intercreditor Agreement (the amount of any such withdrawal being an “Applied Special Termination Advance”) shall thereafter (subject to Section 2.06(b)) be
treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon; provided, further, that if, following the making of a Special Termination Advance, the
Liquidity Provider delivers a Termination Notice to the Borrower pursuant to Section 6.01, such Special Termination Advance shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the
Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof and treated as an Applied Special Termination Advance for purposes of Section 2.6(c) of the Intercreditor Agreement, and, provided,
further, that if, after making a Provider Advance, the Liquidity Provider delivers a Special Termination Notice to the Borrower pursuant to Section 6.02, any Unapplied Provider Advance shall be converted to and treated as a Special
Termination Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof under the Intercreditor Agreement. The Borrower and the Liquidity Provider agree
that the repayment in full of each Interest Advance, the Special Termination Advance and Final Advance on the date such Advance is made is intended to be a contemporaneous exchange for new value given to the Borrower by the Liquidity Provider. 

Section 2.06    Repayments of Provider Advances. (a) Amounts advanced hereunder in respect of a Provider
Advance shall be deposited in the Class A Cash Collateral Account, invested and withdrawn from the Class A Cash Collateral Account as set forth in Sections 3.5(c), (d), (e) and (f) of the Intercreditor Agreement. Subject to
Sections 2.07 and 2.09, the Borrower agrees to pay to the Liquidity Provider, on each Regular Distribution Date, commencing on the first Regular Distribution Date after the making of a Provider Advance, interest on the principal amount of any such
Provider Advance as provided in Section 3.07; provided, however, that amounts in respect of a Provider Advance withdrawn from the Class A Cash Collateral Account for the purpose of paying interest on the Class A
Certificates in accordance with Section 3.5(f) of the Intercreditor Agreement (the amount of any such withdrawal being (y) in the case of a Downgrade Advance, an “Applied Downgrade Advance” and (z) in the case
of a Non-Extension Advance, an “Applied Non-Extension Advance” and, together with an Applied Downgrade Advance, an “Applied Provider
Advance”) shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the dates on which such
interest is payable; provided, further, however, that if, following the making of a Provider Advance, the Liquidity Provider delivers a Termination Notice to the Borrower pursuant to Section 6.01 hereof, such Provider Advance
shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate 

  
 12 

 [Revolving Credit Agreement (2019-2A)] 

 

 
for interest payable thereon and the obligation for repayment thereof and treated as an Applied Downgrade Advance or Applied Non-Extension Advance, as the
case may be, for the purposes of Section 2.6(c) of the Intercreditor Agreement. Subject to Sections 2.07 and 2.09 hereof, immediately upon the withdrawal of any amounts from the Class A Cash Collateral Account on account of a
reduction in the Required Amount, the Borrower shall repay to the Liquidity Provider a portion of the Provider Advances in a principal amount equal to the amount of such reduction, plus interest on the principal amount prepaid as provided in
Section 3.07 hereof. 
 (b)    At any time when an Applied Provider Advance or an Applied Special Termination
Advance (or any portion thereof) is outstanding, upon the deposit in the Class A Cash Collateral Account of any amount pursuant to clause “fourth” of Section 3.2 of the Intercreditor Agreement (any such amount being a
“Replenishment Amount”) for the purpose of replenishing or increasing the balance thereof up to the amount of the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Provider
Advances or the Applied Special Termination Advance (and of Provider Advances treated as an Interest Advance for purposes of determining the Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such
Replenishment Amount (if multiple Applied Provider Advances are outstanding, such Replenishment Amount to be applied in the order in which such Applied Provider Advances have been made, starting with the earliest) and (ii) the aggregate
outstanding principal amount of all Unapplied Provider Advances or of the Unapplied Special Termination Advance shall be automatically increased by the amount of such Replenishment Amount. 

(c)    Upon the provision of a Replacement Liquidity Facility in replacement of this Agreement in accordance with
Section 3.5(e) of the Intercreditor Agreement, amounts remaining on deposit in the Class A Cash Collateral Account after giving effect to any Applied Provider Advance or Applied Special Termination Advance on the date of such replacement
shall be reimbursed to the replaced Liquidity Provider, but only to the extent such amounts are necessary to repay in full to the replaced Liquidity Provider all amounts owing to it hereunder. 

(d)    If, at any time after making a Downgrade Advance, the Liquidity Provider satisfies the Threshold Rating and
delivers a written notice to that effect to the Borrower and United, as of the second Business Day following receipt of such notice, (i) the Unapplied Downgrade Advance shall be withdrawn from the Class A Cash Collateral Account and
reimbursed to the Liquidity Provider, (ii) the Maximum Commitment shall be reinstated by an amount equal to the amount of such Unapplied Downgrade Advance so reimbursed, but not to exceed the Maximum Commitment and the obligation of the
Liquidity Provider to make Advances shall be reinstated in an equal amount, and (iii) the proviso in the definition of Maximum Available Commitment shall no longer apply to such Downgrade Advance. 

Section 2.07    Payments to the Liquidity Provider Under the Intercreditor Agreement. In order to provide for
payment or repayment to the Liquidity Provider of any amounts hereunder, the Intercreditor Agreement provides that amounts available and referred to in Articles II and III of the Intercreditor Agreement, to the extent payable to the
Liquidity Provider pursuant to the terms of the Intercreditor Agreement (including, without limitation, Section 3.5(f) of the Intercreditor Agreement), shall be paid to the Liquidity Provider in accordance with the terms thereof. Amounts so
paid to, and not required to be returned by, the Liquidity Provider shall be 

  
 13 

 [Revolving Credit Agreement (2019-2A)] 

 

 
applied by the Liquidity Provider to Liquidity Obligations then due and payable in accordance with the Intercreditor Agreement and shall discharge in full the corresponding obligations of the
Borrower hereunder (or, if not provided for in the Intercreditor Agreement, then in such manner as the Liquidity Provider shall deem appropriate). 

Section 2.08    Book Entries. The Liquidity Provider shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower resulting from Advances made from time to time and the amounts of principal and interest payable hereunder and paid from time to time in respect thereof; provided,
however, that the failure by the Liquidity Provider to maintain such account or accounts shall not affect the obligations of the Borrower in respect of Advances. 

Section 2.09    Payments from Available Funds Only. All payments to be made by the Borrower under this
Agreement, including, without limitation, Sections 7.05 and 7.07, shall be made only from the amounts that constitute Scheduled Payments, Special Payments or payments under Section 8.1 of the Participation Agreements and payments under the Fee
Letter applicable to this Agreement and Section 6 of the Note Purchase Agreement and only to the extent that the Borrower shall have sufficient income or proceeds therefrom to enable the Borrower to make payments in accordance with the terms
hereof after giving effect to the priority of payments provisions set forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will look solely to such amounts in respect of payments to be made by the Borrower hereunder to the
extent available for distribution to it as provided in the Intercreditor Agreement and this Agreement and that the Borrower, in its individual capacity, is not personally liable to it for any amounts payable or liability under this Agreement except
as expressly provided in this Agreement, the Intercreditor Agreement or any Participation Agreement. Amounts on deposit in the Class A Cash Collateral Account shall be available to the Borrower to make payments under this Agreement only to the
extent and for the purposes expressly contemplated in Section 3.5(f) of the Intercreditor Agreement. 

Section 2.10    Non-Extension of the Expiry Date; Non-Extension Advance. If in any calendar year the Liquidity Provider advises the Borrower before the 25th day prior to the anniversary date of the Closing
Date in such calendar year (such 25th day, the “Notice Date”) that the Expiry Date shall not be extended beyond such anniversary date (and if this Agreement shall not have been
replaced in accordance with Section 3.5(e) of the Intercreditor Agreement), the Borrower shall be entitled on and after such Notice Date (but prior to the then effective Expiry Date) to request a
Non-Extension Advance in accordance with Section 2.02(b) hereof and Section 3.5(d) of the Intercreditor Agreement; provided, however, that if in any calendar year the Liquidity Provider
does not so advise the Borrower before the Notice Date in such calendar year, the Expiry Date shall be automatically extended to the anniversary date of the Closing Date in the next calendar year. 

ARTICLE III 

OBLIGATIONS OF THE BORROWER 

Section 3.01    Increased Costs. The Borrower shall pay to the Liquidity Provider from time to time such
amounts as may be necessary to compensate the Liquidity Provider for any 

  
 14 

 [Revolving Credit Agreement (2019-2A)] 

 

 
increased costs incurred by the Liquidity Provider which are attributable to its making or maintaining any Advances hereunder or its obligation to make any such Advances hereunder, or any
reduction in any amount receivable by the Liquidity Provider under this Agreement or the Intercreditor Agreement in respect of any such Advances or such obligation (such increases in costs and reductions in amounts receivable being herein called
“Additional Costs”), resulting from any change after the date of this Agreement in U.S. federal, state, municipal, or foreign laws or regulations (including Regulation D of the Board of Governors of the Federal Reserve
System), or the adoption or making after the date of this Agreement of any interpretations, directives, or requirements applying to a class of banks including the Liquidity Provider under any U.S. federal, state, municipal, or any foreign laws or
regulations (whether or not having the force of law) by any court, central bank or monetary authority charged with the interpretation or administration thereof (a “Regulatory Change”), which: (1) changes the basis of
taxation of any amounts payable to the Liquidity Provider under this Agreement in respect of any such Advances or such obligation (other than Excluded Taxes); or (2) imposes or modifies any reserve, special deposit, compulsory loan or similar
requirements relating to any extensions of credit or other assets of, or any deposits with other liabilities of, the Liquidity Provider (including any such Advances or such obligation or any deposits referred to in the definition of LIBOR Rate or
related definitions). For the avoidance of doubt, any Regulatory Changes based on the consultative papers of The Basel Committee on Banking Supervision of December 2009 entitled “Strengthening the resilience of the banking sector” and
“International framework for liquidity risk measurement, standards and monitoring”, in each case together with any amendments thereto (collectively, “Basel III”), will not be treated, for purposes of determining
whether the Liquidity Provider is entitled to compensation under this Section 3.01, as having been adopted or having come into effect before the date hereof, and any such Regulatory Changes based on Basel III shall be determined to be adopted
only when the national banking supervisory authorities, or other relevant administrative or legislative bodies having primary jurisdiction or regulatory authority over the Liquidity Provider, adopt any such Regulatory Changes based on Basel III in
the primary jurisdiction of the Liquidity Provider. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would
avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider. 

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.01 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts
owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.01 of the effect of any Regulatory Change on its costs of making or maintaining Advances or on amounts receivable by it in respect of Advances, and
of the additional amounts required to compensate the Liquidity Provider in respect of any Additional Costs, shall be prima facie evidence of the amount owed under this Section. 

Notwithstanding the preceding two paragraphs, the Liquidity Provider and the Subordination Agent agree that any permitted assignee or
participant of the initial Liquidity Provider which is not a bank shall not be entitled to the benefits of the preceding two paragraphs (but without limiting the provisions of Section 7.08 hereof). 

  
 15 

 [Revolving Credit Agreement (2019-2A)] 

 

 Section 3.02    Capital Adequacy and Liquidity Coverage. If
(1) the adoption, after the date hereof, of any applicable governmental law, rule or regulation regarding capital adequacy or liquidity coverage, (2) any change, after the date hereof, in the interpretation or administration of any such
law, rule or regulation by any central bank or other governmental authority charged with the interpretation or administration thereof or (3) compliance by the Liquidity Provider or any corporation or bank controlling the Liquidity Provider with
any applicable guideline or request of general applicability, issued after the date hereof, by any central bank or other governmental authority (whether or not having the force of law) that constitutes a change of the nature described in
clause (2), has the effect of (x) requiring an increase in the amount of capital or liquid assets required to be maintained by the Liquidity Provider or any corporation or bank controlling the Liquidity Provider, or (y) reducing the
rate of return on assets or capital of the Liquidity Provider (or such corporation or bank) and such adoption, change or compliance, as the case may be, relates to a category of claims or assets that includes the Liquidity Provider’s
obligations hereunder (including funded obligations) and other similar obligations, the Borrower shall, subject to the provisions of the next paragraph, pay to the Liquidity Provider from time to time such additional amount or amounts as are
necessary to compensate the Liquidity Provider for such portion of such increase or reduction as shall be reasonably allocable to the Liquidity Provider’s obligations to the Borrower hereunder. For the avoidance of doubt, the adoption of any
law, rule or regulation described in clause (1) of the first sentence of this Section 3.02, and the taking of any action described in clauses (2) and (3) of such sentence, that in each case is based on Basel III, will not be treated,
for purposes of determining whether the Liquidity Provider (or any corporation or bank controlling the Liquidity Provider) is entitled to compensation under this Section 3.02, as having been adopted, come into effect, been issued or been taken
before the date hereof, and any such law, rule or regulation and any of the actions described in clauses (2) and (3) of such sentence that is based on Basel III shall be determined to have been adopted, come into effect, been issued or been
taken only when the central bank or other legislative or administrative governmental authorities in the primary jurisdiction of the Liquidity Provider (or any corporation or bank controlling the Liquidity Provider) adopt any such law, rule or
regulation or take any such actions. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would avoid the need
for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise materially disadvantageous to the Liquidity Provider. 

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.02 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts
owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.02 of the effect of any increase in the amount of capital or liquid assets required to be maintained by the Liquidity Provider and of the amount
allocable to the Liquidity Provider’s obligations to the Borrower hereunder shall be conclusive evidence of the amounts owed under this Section, absent manifest error. 

  
 16 

 [Revolving Credit Agreement (2019-2A)] 

 

 Notwithstanding the preceding two paragraphs, the Liquidity Provider and the Subordination
Agent agree that any permitted assignee or participant of the initial Liquidity Provider which is not a bank shall not be entitled to the benefits of the preceding two paragraphs (but without limiting the provisions of Section 7.08 hereof).

 Section 3.03    Payments Free of Deductions. (a) Unless required by applicable law, all payments
made by the Borrower under this Agreement shall be made free and clear of, and without reduction for or on account of, any present or future stamp or other taxes, levies, imposts, duties, charges, fees, deductions, withholdings, restrictions or
conditions of any nature whatsoever now or hereafter imposed on, levied, collected, withheld or assessed, excluding Excluded Taxes (such non-excluded taxes being referred to herein, collectively, as
“Non-Excluded Taxes” and each, individually, as a “Non-Excluded Tax”). If any
Non-Excluded Taxes are required to be withheld from any amounts payable to the Liquidity Provider under this Agreement, (i) the Borrower shall within the time prescribed therefor by applicable law pay to
the appropriate governmental or taxing authority the full amount of any such Non-Excluded Taxes (and any additional Non-Excluded Taxes in respect of the additional
amounts payable under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) the amounts so payable to the Liquidity Provider shall be
increased to the extent necessary to yield to the Liquidity Provider (after payment of all Non-Excluded Taxes) interest or any other such amounts payable under this Agreement at the rates or in the amounts
specified in this Agreement. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would avoid the
need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider. From time to time upon the
reasonable request of the Borrower, the Liquidity Provider agrees to provide to the Borrower two original Internal Revenue Service Forms W-8BEN-E, W-8ECI or W-9, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that the Liquidity Provider is exempt from or entitled to
a reduced rate of United States withholding tax on payments pursuant to this Agreement. Within 30 days after the date of each payment hereunder, the Borrower shall furnish to the Liquidity Provider the original or a certified copy of (or other
documentary evidence of) the payment of the Non-Excluded Taxes applicable to such payment. 

(b)    Unless required by applicable law, all payments (including, without limitation, Advances) made by the Liquidity
Provider under this Agreement shall be made free and clear of, and without reduction for or on account of, any Taxes. If any Taxes are required to be withheld or deducted from any amounts payable to the Borrower under this Agreement, the Liquidity
Provider shall (i) within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the additional amounts payable under
clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) pay to the Borrower an additional amount which (after deduction of all such Taxes)
will be sufficient to yield to the Borrower the full amount which would have been received by it had no such withholding or deduction been made. Within 30 days after the date of each payment hereunder, the Liquidity Provider shall furnish to the
Borrower the original or a certified copy of (or other documentary evidence of) the payment of the Taxes applicable to such payment. 

  
 17 

 [Revolving Credit Agreement (2019-2A)] 

 

 (c)    On or before the Closing Date, the Borrower shall provide the
Liquidity Provider with a fully executed Internal Revenue Service Form W-9, showing a complete exemption from U.S federal backup withholding tax. If any other exemption from, or reduction in the rate of, any
Taxes required to be borne by the Liquidity Provider under Section 3.03(b) is reasonably available to the Borrower without providing any information regarding the holders or beneficial owners of the Certificates, the Borrower shall deliver the
Liquidity Provider such form or forms and such other evidence of the eligibility of the Borrower for such exemption or reductions (but without any requirement to provide any information regarding the holders or beneficial owners of the Certificates)
as the Liquidity Provider may reasonably identify to the Borrower as being required as a condition to exemption from, or reduction in the rate of, such Taxes. 

(d)    If a payment made to the Liquidity Provider or Borrower hereunder would be subject to U.S. federal withholding Tax
imposed by FATCA if the Borrower or Liquidity Provider, as applicable, were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471 (b) or 1472 (b) of the U.S. Internal Revenue Code, as
applicable), it shall deliver to the Borrower or the Liquidity Provider, as applicable, at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or Liquidity Provider, as applicable, such documentation
prescribed by applicable law (including as prescribed by Section 1471 (b)(3)(C)(i) of the U.S. Internal Revenue Code) and such additional documentation reasonably requested by the Borrower or Liquidity Provider, as applicable, as may be
necessary for the Borrower or Liquidity Provider, as applicable, to comply with its obligations under FATCA and to determine that the Liquidity Provider or Borrower has complied with the Liquidity Provider’s or Borrower’s obligations under
FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this paragraph, “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 

Section 3.04    Payments. The Borrower shall make or cause to be made each payment to the Liquidity Provider
under this Agreement so as to cause the same to be received by the Liquidity Provider not later than 1:00 P.M. (New York City time) on the day when due. The Borrower shall make all such payments in lawful money of the United States of America,
to the Liquidity Provider in immediately available funds, by wire transfer to the account specified for the Liquidity Provider in Schedule B or to such other U.S. bank account as the Liquidity Provider may from time to time direct the Borrower in
writing. 
 Section 3.05    Computations. All computations of interest based on the Base Rate shall be made
on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the LIBOR Rate (other than where the LIBOR Rate is determined based on the Base Rate or any Benchmark Replacement Rate with determinations based
on a year of 365 or 366 days, as the case may be) shall be made on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is
payable. 
 Section 3.06    Payment on Non-Business Days. Whenever
any payment to be made hereunder to the Liquidity Provider shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and no additional interest shall be due as a result. If any
payment in respect of interest on an Advance is so deferred to the next succeeding Business Day, such deferral shall not delay the commencement of the next Interest

Period for such Advance (if such Advance is a LIBOR Advance) or reduce the number of days for which interest will be payable on such Advance on the next interest payment date for such Advance.

 Section 3.07    Interest. (a) Subject to Section 2.09, the Borrower shall pay, or shall cause
to be paid, without duplication, interest on (i) the unpaid principal amount of each Advance from and including the date of such Advance (or, in the case of an Applied Provider Advance or Applied Special Termination Advance, from and including
the date on which the amount thereof was withdrawn from the Class A Cash Collateral Account to pay interest on the Class A Certificates) to but excluding the date such principal amount shall be paid in full (or, in the case of an Applied
Provider Advance or Applied Special Termination Advance, the date on which the Class A Cash Collateral Account is fully replenished in respect of such Advance) and (ii) any other amount due hereunder (whether fees, commissions, expenses or
other amounts or, to the extent permitted by law, installments of interest on Advances or any such other amount) which is not paid when due (whether at stated maturity, by acceleration or otherwise) from and including the due date thereof to but
excluding the date such amount is paid in full, in each such case, at a fluctuating interest rate per annum for each day equal to the Applicable Liquidity Rate (as defined below) for such Advance or such other amount, as the case may be, as in
effect for such day, but in no event at a rate per annum greater than the maximum rate permitted by applicable law; provided, however, that, if at any time the otherwise applicable interest rate as set forth in this Section 3.07
shall exceed the maximum rate permitted by applicable law, then any subsequent reduction in such interest rate will not reduce the rate of interest payable pursuant to this Section 3.07 below the maximum rate permitted by applicable law until
the total amount of interest accrued equals the amount of interest that would have accrued if such otherwise applicable interest rate as set forth in this Section 3.07 had at all times been in effect. 

(b)    Except as provided in clause (e) below, each Advance will be either a Base Rate Advance or a LIBOR Advance as
provided in this Section. Each such Advance will be a Base Rate Advance for the period from the date of its Borrowing to (but excluding) the third LIBOR Business Day following the Liquidity Provider’s receipt of the Notice of Borrowing for such
Advance. Thereafter, such Advance shall be a LIBOR Advance. 
 (c)    Each LIBOR Advance shall bear interest during each
Interest Period at a rate per annum equal to the LIBOR Rate for such Interest Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on the last day of such Interest Period and, in the event of the payment of principal of such
LIBOR Advance on a day other than such last day, on the date of such payment (to the extent of interest accrued on the amount of principal repaid). 

(d)    Each Base Rate Advance shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin
for such Base Rate Advance, payable in arrears on each Regular Distribution Date and, in the event of the payment of principal of such Base Rate Advance on a day other than a Regular Distribution Date, on the date of such payment (to the extent of
interest accrued on the amount of principal repaid). 
 (e)    Each outstanding Unapplied
Non-Extension Advance, Unapplied Downgrade Advance and Unapplied Special Termination Advance shall bear interest in an amount equal to the Investment Earnings on amounts on deposit in the Class A Cash
Collateral Account plus the 

  
 19 

 [Revolving Credit Agreement (2019-2A)] 

 

 
Applicable Margin for such Unapplied Non-Extension Advance, Unapplied Downgrade Advance or Unapplied Special Termination Advance, as applicable, on the
amount of such Unapplied Non-Extension Advance, Unapplied Downgrade Advance or Unapplied Special Termination Advance, as applicable, from time to time, payable in arrears on each Regular Distribution Date.

 (f)    Each amount not paid when due hereunder (whether fees, commissions, expenses or other amounts or, to the
extent permitted by applicable law, installments of interest on Advances but excluding Advances) shall bear interest at a rate per annum equal to the Base Rate plus 2.00% per annum until paid. 

(g)    If at any time, the Liquidity Provider shall have determined (which determination shall be conclusive and binding
upon the Borrower, absent manifest error) that, by reason of circumstances affecting the relevant interbank lending market generally (other than a Benchmark Replacement Event), the LIBOR Rate determined or to be determined for the current or the
immediately succeeding Interest Period will not adequately and fairly reflect the cost to the Liquidity Provider (as conclusively certified by the Liquidity Provider, absent manifest error) of making or maintaining LIBOR Advances, the Liquidity
Provider shall give facsimile or telephonic notice thereof (a “Rate Determination Notice”) to the Borrower (any such telephonic notice to be promptly confirmed in writing and transmitted by telecopier to the Borrower in
accordance with Section 7.02). If such notice is given, then the outstanding principal amount of the LIBOR Advances shall be converted to Base Rate Advances effective from the date of the Rate Determination Notice; provided that the
Applicable Liquidity Rate in respect of such Base Rate Advances shall be increased by one percent (1.00%). The Liquidity Provider shall withdraw a Rate Determination Notice given hereunder when the Liquidity Provider determines that the
circumstances giving rise to such Rate Determination Notice no longer apply to the Liquidity Provider, and the Base Rate Advances shall be converted to LIBOR Advances effective as of the first day of the next succeeding Interest Period after the
date of such withdrawal. 
 (h)    Each change in the Base Rate shall become effective immediately. The rates of
interest specified in this Section 3.07 with respect to any Advance or other amount shall be referred to as the “Applicable Liquidity Rate”. 

Section 3.08    Replacement of Borrower. From time to time and subject to the successor Borrower’s
meeting the eligibility requirements set forth in Section 6.9 of the Intercreditor Agreement applicable to the Subordination Agent, upon the effective date and time specified in a written and completed Notice of Replacement Subordination Agent
in substantially the form of Annex VI attached hereto (a “Notice of Replacement Subordination Agent”) delivered to the Liquidity Provider by the then Borrower, the successor Borrower designated therein shall be substituted
for the Borrower for all purposes hereunder. 
 Section 3.09    Funding Loss Indemnification. The Borrower
shall pay to the Liquidity Provider, upon the request of the Liquidity Provider, such amount or amounts as shall be sufficient (in the reasonable opinion of the Liquidity Provider) to compensate it for any loss, cost, or expense incurred by reason
of the liquidation or redeployment of deposits or other funds acquired by the Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of anticipated profits) incurred as a result of: 

(1)    Any repayment of a LIBOR Advance on a date other than the last day of the Interest Period for such
Advance; or 

  
 20 

 [Revolving Credit Agreement (2019-2A)] 

 

 (2)    Any failure by the Borrower to borrow a LIBOR
Advance on the date for borrowing specified in the relevant notice under Section 2.02. 
 Calculation of all amounts payable to the
Liquidity Provider under this Section 3.09 shall be made as though the Liquidity Provider had actually funded the related LIBOR Advance through the purchase of a LIBOR deposit bearing interest at the LIBOR Rate in an amount equal to its LIBOR
Advance and having a maturity comparable to the relevant Interest Period; provided, however, that the Liquidity Provider may fund any LIBOR Advance in any manner it sees fit and the foregoing assumptions shall be utilized only for the
purposes of calculating amounts payable under this Section 3.09. 
 Section 3.10    Illegality.
Notwithstanding any other provision in this Agreement, if any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by the Liquidity Provider (or its Facility Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall
make it unlawful or impossible for the Liquidity Provider (or its Facility Office) to maintain or fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity Provider, the outstanding principal amount of the LIBOR Advances shall be
converted to Base Rate Advances (a) immediately upon demand of the Liquidity Provider, if such change or compliance with such request, in the judgment of the Liquidity Provider, requires immediate repayment; or (b) at the expiration of the
last Interest Period to expire before the effective date of any such change or request. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Facility
Office if making such change would avoid or cure the aforesaid illegality and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

Section 7.01    Amendments, Etc. No amendment or waiver of any provision of this Agreement, nor consent
to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Liquidity Provider, and, in the case of an amendment or of a waiver by the Borrower, the Borrower, and then such waiver
or consent shall be effective only in the specific instance and for the specific purpose for which given. 

Section 7.02    Notices, Etc. Except as otherwise expressly provided herein, all notices and other
communications provided for hereunder shall be in writing (including telecopier and mailed or delivered or sent by telecopier) addressed to the applicable party at its address specified on Schedule B or to such other address as shall be designated

either party shall in addition be delivered to each of the parties to the Participation Agreements at their respective addresses set forth therein. 

Section 7.03    No Waiver; Remedies. No failure on the part of the Liquidity Provider to exercise, and no
delay in exercising, any right under this Agreement shall operate as a waiver 

  
 25 

 [Revolving Credit Agreement (2019-2A)] 

 

 
thereof; nor shall any single or partial exercise of any right under this Agreement preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided
are cumulative and not exclusive of any remedies provided by law. 
 Section 7.04    Further Assurances. The
Borrower agrees to do such further acts and things and to execute and deliver to the Liquidity Provider such additional assignments, agreements, powers and instruments as the Liquidity Provider may reasonably require or deem advisable to carry into

Section 7.05    Indemnification; Survival of Certain Provisions. The Liquidity Provider shall be indemnified
hereunder to the extent and in the manner described in Section 8.1 of the Participation Agreements. In addition, the Borrower agrees to indemnify, protect, defend and hold harmless the Liquidity Provider from, against and in respect of, and
shall pay on demand, all Expenses of any kind or nature whatsoever (other than any Expenses of the nature described in Section 3.01, 3.02 or 7.07 hereof or in the Fee Letter applicable to this Agreement (regardless of whether indemnified
against pursuant to said Sections or in such Fee Letter)), that may be imposed, incurred by or asserted against any Liquidity Indemnitee, in any way relating to, resulting from, or arising out of or in connection with any action, suit or proceeding
by any third party against such Liquidity Indemnitee and relating to this Agreement, the Fee Letter applicable to this Agreement, the Intercreditor Agreement or any Financing Agreement; provided, however, that the Borrower shall not be
required to indemnify, protect, defend and hold harmless any Liquidity Indemnitee in respect of any Expense of such Liquidity Indemnitee to the extent such Expense is (i) attributable to the gross negligence or willful misconduct of such
Liquidity Indemnitee or any other Liquidity Indemnitee, (ii) ordinary and usual operating overhead expense, or (iii) attributable to the failure by such Liquidity Indemnitee or any other Liquidity Indemnitee to perform or observe any
agreement, covenant or condition on its part to be performed or observed in this Agreement, the Intercreditor Agreement, the Fee Letter applicable to this Agreement or any other Operative Agreement to which it is a party. The indemnities contained
in Section 8.1 of the Participation Agreements, and the provisions of Sections 3.01, 3.02, 3.03, 3.09, 7.05 and 7.07 hereof, shall survive the termination of this Agreement. 

Section 7.06    Liability of the Liquidity Provider. (a) Neither the Liquidity Provider nor any of its
officers, employees, directors or Affiliates shall be liable or responsible for: (i) the use which may be made of the Advances or any acts or omissions of the Borrower or any beneficiary or transferee in connection therewith; (ii) the
validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; or (iii) the making of Advances by the Liquidity
Provider against delivery of a Notice of Borrowing and other documents which do not comply with the terms hereof; provided, however, that the Borrower shall have a claim against the Liquidity Provider, and the Liquidity Provider shall
be liable to the Borrower, to the extent of any damages suffered by the Borrower which were the result of (A) the Liquidity Provider’s willful misconduct or negligence in determining whether documents presented hereunder comply with the
terms hereof, or (B) any breach by the Liquidity Provider of any of the terms of this Agreement, including, but not limited to, the Liquidity Provider’s failure to make lawful payment hereunder after the delivery to it by the Borrower of a
Notice of Borrowing strictly 

  
 26 

 [Revolving Credit Agreement (2019-2A)] 

 

 
complying with the terms and conditions hereof. In no event, however, shall the Liquidity Provider be liable on any theory of liability for any special, indirect, consequential or punitive
damages (including, without limitation, any loss of profits, business or anticipated savings). 
 (b)    Neither the
Liquidity Provider nor any of its officers, employees, directors or Affiliates shall be liable or responsible in any respect for (i) any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice,
however transmitted, in connection with this Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action, inaction or omission which may be taken by it in good faith, absent willful misconduct or gross negligence (in which
event the extent of the Liquidity Provider’s potential liability to the Borrower shall be limited as set forth in the immediately preceding paragraph), in connection with this Agreement or any Notice of Borrowing. 

Section 7.07    Costs, Expenses and Taxes. The Borrower agrees to pay, or cause to be paid (A) on the
Effective Date and on such later date or dates on which the Liquidity Provider shall make demand, all reasonable out-of-pocket costs and expenses (including, without
limitation, the reasonable fees and expenses of outside counsel for the Liquidity Provider) of the Liquidity Provider in connection with the preparation, negotiation, execution, delivery, filing and recording of this Agreement, any other Operative
Agreement and any other documents which may be delivered in connection with this Agreement and (B) on demand, all reasonable costs and expenses (including reasonable counsel fees and expenses) of the Liquidity Provider in connection with
(i) the enforcement of this Agreement or any other Operative Agreement, (ii) the modification or amendment of, or supplement to, this Agreement or any other Operative Agreement or such other documents which may be delivered in connection
herewith or therewith (whether or not the same shall become effective) or any waiver or consent thereunder (whether or not the same shall be effective), (iii) the replacement of this Agreement by a Replacement Liquidity Facility pursuant to
Section 3.5(e)(i) of the Intercreditor Agreement or (iv) any action or proceeding relating to any order, injunction, or other process or decree restraining or seeking to restrain the Liquidity Provider from paying any amount under this
Agreement, the Intercreditor Agreement or any other Operative Agreement or otherwise affecting the application of funds in the Class A Cash Collateral Account. In addition, the Borrower shall pay any and all recording, stamp and other similar
taxes and fees payable or determined to be payable in connection with the execution, delivery, filing and recording of this Agreement, any other Operative Agreement and such other documents, and agrees to hold the Liquidity Provider harmless from
and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such taxes or fees. 

Section 7.08    Binding Effect; Participations. (a) This Agreement shall be binding upon and inure to the
benefit of the Borrower and the Liquidity Provider and their respective successors and assigns, except that neither the Liquidity Provider (except as otherwise provided in this Section 7.08 and in Section 3.5(l) of the Intercreditor
Agreement) nor (except as contemplated by Section 3.08) the Borrower shall have the right to assign its rights or obligations hereunder or any interest herein without the prior written consent of the other party, subject to the requirements of
Section 7.08(b). The Liquidity Provider may grant participations herein or in any of its rights hereunder (including, without limitation, funded participations and participations in rights to receive interest payments hereunder) and under the
other Operative Agreements to such Persons (other than United and its Affiliates) as the Liquidity Provider may in its sole 

  
 27 

 [Revolving Credit Agreement (2019-2A)] 

 

 
discretion select, subject to the requirements of Section 7.08(b). No such granting of participations by the Liquidity Provider, however, will relieve the Liquidity Provider of its
obligations hereunder. In connection with any participation or any proposed participation, the Liquidity Provider may disclose to the participant or the proposed participant any information that the Borrower is required to deliver or to disclose to
the Liquidity Provider pursuant to this Agreement. The Borrower acknowledges and agrees that the Liquidity Provider’s source of funds may derive in part from its participants. Accordingly, references in this Agreement and the other Operative
Agreements to determinations, reserve, capital adequacy and liquidity coverage requirements, increased costs, reduced receipts, additional amounts due pursuant to Section 3.03 and the like as they pertain to the Liquidity Provider shall be
deemed also to include those of each of its participants that are banks (subject, in each case, to the maximum amount that would have been incurred by or attributable to the Liquidity Provider directly if the Liquidity Provider, rather than the
participant, had held the interest participated). 
 (b)    If, pursuant to subsection (a) above, the Liquidity
Provider sells any participation in this Agreement to any bank or other entity (each, a “Transferee”), then, concurrently with the effectiveness of such participation, the Transferee shall (i) represent to the Liquidity
Provider (for the benefit of the Liquidity Provider and the Borrower) either (A) that it is incorporated under the laws of the United States or a state thereof or (B) that under applicable law and treaties, no taxes will be required to be
withheld with respect to any payments to be made to such Transferee in respect of this Agreement, (ii) furnish to the Liquidity Provider and the Borrower either (x) a statement that it is incorporated under the laws of the United States or
a state thereof or (y) if it is not so incorporated, two copies of a properly completed United States Internal Revenue Service Form W-8ECI, Form W-8BEN-E or Form W-9, as appropriate, or other applicable form, certificate or document prescribed by the Internal Revenue Service certifying, in each case, such
Transferee’s entitlement to a complete exemption from United States federal withholding tax in respect to any and all payments to be made hereunder, and (iii) agree (for the benefit of the Liquidity Provider and the Borrower) to provide
the Liquidity Provider and the Borrower a new Form W-8ECI, Form W-8BEN-E or Form W-9, as
appropriate, (A) on or before the date that any such form expires or becomes obsolete or (B) after the occurrence of any event requiring a change in the most recent form previously delivered by it and prior to the immediately following due
date of any payment by the Borrower hereunder, certifying in the case of a Form W-8ECI, Form W-8BEN-E or Form W-9 that such Transferee is entitled to a complete exemption from United States federal withholding tax on payments under this Agreement. Unless the Borrower has received forms or other documents reasonably
satisfactory to it (and required by applicable law) indicating that payments hereunder are not subject to United States federal withholding tax, the Borrower will withhold taxes as required by law from such payments at the applicable statutory rate.

 (c)    Notwithstanding the other provisions of this Section 7.08, the Liquidity Provider may assign and pledge
all or any portion of the Advances owing to it to any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by
such Federal Reserve Bank, provided that any payment in respect of such assigned Advances made by the Borrower to the Liquidity Provider in accordance with the terms of this Agreement shall satisfy the Borrower’s obligations hereunder in
respect of such assigned Advance to the extent of such payment. No such assignment shall release the Liquidity Provider from its obligations hereunder.

 Section 7.09    Severability. Any provision of this Agreement
which is prohibited, unenforceable or not authorized in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition, unenforceability or non-authorization without
invalidating the remaining provisions hereof or affecting the validity, enforceability or legality of such provision in any other jurisdiction.

OF THE STATE OF NEW YORK. 
 Section 7.11    Submission to Jurisdiction; Waiver of Jury Trial; Waiver of

agrees, on the terms and conditions hereinafter set forth, to make Advances to the Borrower from time to time on any Business Day during the period from the Effective Date until 1:00 p.m. (New York City time) on the Expiry Date (unless the

 [Revolving Credit Agreement (2019-2B)] 

 

 Section 2.02    Making the Advances. (a) Interest
Advances shall be made in one or more Borrowings by delivery to the Liquidity Provider of one or more written and completed Notices of Borrowing in substantially the form of Annex I attached hereto, signed by a Responsible Officer of the
Borrower, in an amount not exceeding the Maximum Available Commitment at such time and shall be used solely for the payment when due of interest on the Class B Certificates at the Stated Interest Rate therefor in accordance with
Section 3.5(a) of the Intercreditor Agreement. Each Interest Advance made hereunder shall automatically reduce the Maximum Available Commitment and the amount available to be borrowed hereunder by subsequent Advances by the amount of such
Interest Advance (subject to reinstatement as provided in the next sentence). Upon repayment to the Liquidity Provider in full or in part of the amount of any Interest Advance made pursuant to this Section 2.02(a), together with accrued
interest thereon (as provided herein), the Maximum Available Commitment shall be reinstated by the amount of such repaid Interest Advance but not to exceed the Maximum Commitment; provided, however, that, subject to
Section 2.06(d), the Maximum Available Commitment shall not be so reinstated at any time if (x) (i) a Liquidity Event of Default shall have occurred and be continuing and (ii) there is a Performing Note Deficiency or (y) a Final
Advance, a Special Termination Advance, a Downgrade Advance or a Non-Extension Advance shall have been made or an Interest Advance shall have been converted into a Final Advance. 

(b)    A Non-Extension Advance shall be made in a single Borrowing if this
Agreement is not extended in accordance with Section 3.5(d) of the Intercreditor Agreement (unless a Replacement Liquidity Facility to replace this Agreement shall have been delivered to the Borrower as contemplated by said Section 3.5(d)
within the time period specified in such Section) by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex II attached hereto, signed by a Responsible Officer of the Borrower, in an
amount equal to the Maximum Available Commitment at such time, and shall be used to fund the Class B Cash Collateral Account in accordance with said Section 3.5(d) and Section 3.5(f) of the Intercreditor Agreement. 

(c)    A Downgrade Advance shall be made in a single Borrowing upon the occurrence of a Downgrade Event (as provided for
in Section 3.5(c) of the Intercreditor Agreement), unless (i) a Replacement Liquidity Facility to replace this Agreement shall have been previously delivered to the Borrower within thirty-five (35) days after the Downgrade Event or
(ii) the relevant Rating Agency shall have provided confirmation within thirty (30) days after the Downgrade Event that such Downgrade Event will not result in a downgrading, withdrawal or suspension by such Rating Agency of the rating
then in effect for the related Class of Certificates, in each case of clause (i) and (ii), in accordance with said Section 3.5(c), by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially
the form of Annex III attached hereto, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used to fund the Class B Cash Collateral Account in accordance with
said Section 3.5(c) and Section 3.5(f) of the Intercreditor Agreement. Upon the occurrence of a Downgrade Event, the Liquidity Provider shall promptly deliver notice thereof to the Borrower, the Class B Trustee and United.

 [Revolving Credit Agreement (2019-2B)] 

 

 (d)    A Final Advance shall be made in a single Borrowing upon the
receipt by the Borrower of a Termination Notice from the Liquidity Provider pursuant to Section 6.01 hereof by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex IV attached
hereto, signed by a Responsible Officer of the Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used to fund the Class B Cash Collateral Account (in accordance with Sections 3.5(f) and 3.5(i) of
the Intercreditor Agreement). 
 (e)    Each Borrowing shall be made on notice in writing (a “Notice of
Borrowing”) in substantially the form required by Section 2.02(a), 2.02(b), 2.02(c), 2.02(d) or 2.02(g), as the case may be, given by the Borrower to the Liquidity Provider. If a Notice of Borrowing is delivered by the Borrower in
respect of any Borrowing no later than 1:00 p.m. (New York City time) on a Business Day, upon satisfaction of the conditions precedent set forth in Section 4.02 with respect to a requested Borrowing, the Liquidity Provider shall make
available to the Borrower, in accordance with its payment instructions, the amount of such Borrowing in U.S. dollars and immediately available funds, before 4:00 p.m. (New York City time) on such Business Day. If a Notice of Borrowing is
delivered by the Borrower in respect of any Borrowing on a day that is not a Business Day or after 1:00 p.m. (New York City time) on a Business Day, upon satisfaction of the conditions precedent set forth in Section 4.02 with respect to a
requested Borrowing, the Liquidity Provider shall make available to the Borrower, in accordance with its payment instructions, the amount of such Borrowing in U.S. dollars and in immediately available funds, before 12:00 Noon (New York City time) on
the first Business Day next following the day of receipt of such Notice of Borrowing. Payments of proceeds of a Borrowing shall be made by wire transfer of immediately available funds to the Borrower in accordance with such wire transfer
instructions as the Borrower shall furnish from time to time to the Liquidity Provider for such purpose. Each Notice of Borrowing shall be irrevocable and binding on the Borrower. Each Notice of Borrowing shall be effective upon receipt of a copy
thereof by the Liquidity Provider at the address specified pursuant to Section 7.02. 
 (f)    Upon the making of
any Advance requested pursuant to a Notice of Borrowing, in accordance with the Borrower’s payment instructions, the Liquidity Provider shall be fully discharged of its obligation hereunder with respect to such Notice of Borrowing, and the
Liquidity Provider shall not thereafter be obligated to make any further Advances hereunder in respect of such Notice of Borrowing to the Borrower or to any other Person. If the Liquidity Provider makes an Advance requested pursuant to a Notice of
Borrowing before 12:00 Noon (New York City time) on the second Business Day after the date of payment specified in Section 2.02(e), the Liquidity Provider shall have fully discharged its obligations hereunder with respect to such Advance and an
event of default shall not have occurred hereunder. Following the making of any Advance pursuant to Section 2.02(b), (c), (d) or (g) hereof to fund the Class B Cash Collateral Account, the Liquidity Provider shall have no
interest in or rights to the Class B Cash Collateral Account, the funds constituting such Advance or any other amounts from time to time on deposit in the Class B Cash Collateral Account; provided that the foregoing shall not affect
or impair the obligations of the Subordination Agent to make the distributions contemplated by Section 3.5(e) or (f) of the Intercreditor Agreement, and provided, further, that the foregoing shall not affect or impair the rights of
the Liquidity Provider to provide written instructions with respect to the investment and reinvestment of amounts in the Class B Cash Collateral Account to the extent provided in Section 2.2(b) of the Intercreditor Agreement. By

  
 10 

 [Revolving Credit Agreement (2019-2B)] 

 

 
paying to the Borrower proceeds of Advances requested by the Borrower in accordance with the provisions of this Agreement, the Liquidity Provider makes no representation as to, and assumes no
responsibility for, the correctness or sufficiency for any purpose of the amount of the Advances so made and requested. 

(g)    A Special Termination Advance shall be made in a single Borrowing upon the receipt by the Borrower of a Special
Termination Notice from the Liquidity Provider pursuant to Section 6.02, by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex VII, signed by a Responsible Officer of the
Borrower, in an amount equal to the Maximum Available Commitment at such time, and shall be used to fund the Class B Cash Collateral Account (in accordance with Section 3.5(f) and Section 3.5(m) of the Intercreditor Agreement). 

Section 2.03    Fees. The Borrower agrees to pay to the Liquidity Provider the fees set forth in the Fee
Letter applicable to this Agreement. 
 Section 2.04    Reductions or Termination of the Maximum Commitment.

 (a)    Automatic Reduction. Promptly following each date on which the Required Amount is reduced as a result
of a reduction in the Pool Balance of the Class B Certificates or otherwise, the Maximum Commitment shall automatically be reduced to an amount equal to such reduced Required Amount (as calculated by the Borrower); provided that on (or, as
applicable, immediately following) the first Regular Distribution Date, the Maximum Commitment shall automatically be reduced to the then Required Amount. The Borrower shall give notice of any such automatic reduction of the Maximum Commitment to
the Liquidity Provider within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not affect such automatic reduction of the Maximum Commitment. 

(b)    Termination. Upon the making of any Provider Advance or Special Termination Advance or the making of or
conversion to a Final Advance hereunder or the occurrence of the Termination Date, the obligation of the Liquidity Provider to make further Advances hereunder shall automatically and irrevocably terminate, and the Borrower shall not be entitled to
request any further Borrowing hereunder, except in the case of a Downgrade Advance, as provided in Section 2.06(d). 

Section 2.05    Repayments of Interest Advances, the Special Termination Advance or the Final Advance. Subject
to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees, without notice of an Advance or demand for repayment from the Liquidity Provider (which notice and demand are hereby waived by the Borrower), to pay, or to cause to be paid, to
the Liquidity Provider on each date on which the Liquidity Provider shall make an Interest Advance, the Special Termination Advance or the Final Advance, an amount equal to (a) the amount of such Advance (any such Advance, until repaid, is
referred to herein as an “Unpaid Advance”) (if multiple Interest Advances are outstanding any such repayment to be applied in the order in which such Interest Advances have been made, starting with the earliest), plus
(b) interest on the amount of each such Unpaid Advance as provided in Section 3.07 hereof; provided that if (i) the Liquidity Provider shall make a Provider Advance at any time after making one or more Interest Advances which
shall not have been repaid in accordance with this Section 2.05 or (ii) this 

  
 11 

 [Revolving Credit Agreement (2019-2B)] 

 

 
Liquidity Facility shall become a Downgraded Facility or Non-Extended Facility at any time when unreimbursed Interest Advances have reduced the Maximum
Available Commitment to zero, then such Interest Advances shall cease to constitute Unpaid Advances and shall be deemed to have been changed into an Applied Downgrade Advance or an Applied Non-Extension
Advance, as the case may be, for all purposes of this Agreement (including, without limitation, for the purpose of determining when such Interest Advance is required to be repaid to the Liquidity Provider in accordance with Section 2.06 and for
the purposes of Section 2.06(b)); provided, further, that amounts in respect of a Special Termination Advance withdrawn from the Class B Cash Collateral Account for the purpose of paying interest on the Class B
Certificates in accordance with Section 3.5(f) of the Intercreditor Agreement (the amount of any such withdrawal being an “Applied Special Termination Advance”) shall thereafter (subject to Section 2.06(b)) be
treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon; provided, further, that if, following the making of a Special Termination Advance, the
Liquidity Provider delivers a Termination Notice to the Borrower pursuant to Section 6.01, such Special Termination Advance shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the
Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof and treated as an Applied Special Termination Advance for purposes of Section 2.6(c) of the Intercreditor Agreement, and, provided,
further, that if, after making a Provider Advance, the Liquidity Provider delivers a Special Termination Notice to the Borrower pursuant to Section 6.02, any Unapplied Provider Advance shall be converted to and treated as a Special
Termination Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the obligation for repayment thereof under the Intercreditor Agreement. The Borrower and the Liquidity Provider agree
that the repayment in full of each Interest Advance, the Special Termination Advance and Final Advance on the date such Advance is made is intended to be a contemporaneous exchange for new value given to the Borrower by the Liquidity Provider. 

Section 2.06    Repayments of Provider Advances. (a) Amounts advanced hereunder in respect of a Provider
Advance shall be deposited in the Class B Cash Collateral Account, invested and withdrawn from the Class B Cash Collateral Account as set forth in Sections 3.5(c), (d), (e) and (f) of the Intercreditor Agreement. Subject to
Sections 2.07 and 2.09, the Borrower agrees to pay to the Liquidity Provider, on each Regular Distribution Date, commencing on the first Regular Distribution Date after the making of a Provider Advance, interest on the principal amount of any such
Provider Advance as provided in Section 3.07; provided, however, that amounts in respect of a Provider Advance withdrawn from the Class B Cash Collateral Account for the purpose of paying interest on the Class B
Certificates in accordance with Section 3.5(f) of the Intercreditor Agreement (the amount of any such withdrawal being (y) in the case of a Downgrade Advance, an “Applied Downgrade Advance” and (z) in the case
of a Non-Extension Advance, an “Applied Non-Extension Advance” and, together with an Applied Downgrade Advance, an “Applied Provider
Advance”) shall thereafter (subject to Section 2.06(b)) be treated as an Interest Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon and the dates on which such
interest is payable; provided, further, however, that if, following the making of a Provider Advance, the Liquidity Provider delivers a Termination Notice to the Borrower pursuant to Section 6.01 hereof, such Provider Advance
shall thereafter be converted to and treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate 

  
 12 

 [Revolving Credit Agreement (2019-2B)] 

 

 
for interest payable thereon and the obligation for repayment thereof and treated as an Applied Downgrade Advance or Applied Non-Extension Advance, as the
case may be, for the purposes of Section 2.6(c) of the Intercreditor Agreement. Subject to Sections 2.07 and 2.09 hereof, immediately upon the withdrawal of any amounts from the Class B Cash Collateral Account on account of a
reduction in the Required Amount, the Borrower shall repay to the Liquidity Provider a portion of the Provider Advances in a principal amount equal to the amount of such reduction, plus interest on the principal amount prepaid as provided in
Section 3.07 hereof. 
 (b)    At any time when an Applied Provider Advance or an Applied Special Termination
Advance (or any portion thereof) is outstanding, upon the deposit in the Class B Cash Collateral Account of any amount pursuant to clause “fourth” of Section 3.2 of the Intercreditor Agreement (any such amount being a
“Replenishment Amount”) for the purpose of replenishing or increasing the balance thereof up to the amount of the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Provider
Advances or the Applied Special Termination Advance (and of Provider Advances treated as an Interest Advance for purposes of determining the Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such
Replenishment Amount (if multiple Applied Provider Advances are outstanding, such Replenishment Amount to be applied in the order in which such Applied Provider Advances have been made, starting with the earliest) and (ii) the aggregate
outstanding principal amount of all Unapplied Provider Advances or of the Unapplied Special Termination Advance shall be automatically increased by the amount of such Replenishment Amount. 

(c)    Upon the provision of a Replacement Liquidity Facility in replacement of this Agreement in accordance with
Section 3.5(e) of the Intercreditor Agreement, amounts remaining on deposit in the Class B Cash Collateral Account after giving effect to any Applied Provider Advance or Applied Special Termination Advance on the date of such replacement
shall be reimbursed to the replaced Liquidity Provider, but only to the extent such amounts are necessary to repay in full to the replaced Liquidity Provider all amounts owing to it hereunder. 

(d)    If, at any time after making a Downgrade Advance, the Liquidity Provider satisfies the Threshold Rating and
delivers a written notice to that effect to the Borrower and United, as of the second Business Day following receipt of such notice, (i) the Unapplied Downgrade Advance shall be withdrawn from the Class B Cash Collateral Account and
reimbursed to the Liquidity Provider, (ii) the Maximum Commitment shall be reinstated by an amount equal to the amount of such Unapplied Downgrade Advance so reimbursed, but not to exceed the Maximum Commitment and the obligation of the
Liquidity Provider to make Advances shall be reinstated in an equal amount, and (iii) the proviso in the definition of Maximum Available Commitment shall no longer apply to such Downgrade Advance. 

Section 2.07    Payments to the Liquidity Provider Under the Intercreditor Agreement. In order to provide for
payment or repayment to the Liquidity Provider of any amounts hereunder, the Intercreditor Agreement provides that amounts available and referred to in Articles II and III of the Intercreditor Agreement, to the extent payable to the
Liquidity Provider pursuant to the terms of the Intercreditor Agreement (including, without limitation, Section 3.5(f) of the Intercreditor Agreement), shall be paid to the Liquidity Provider in accordance with the terms thereof. Amounts so
paid to, and not required to be returned by, the Liquidity Provider shall be 

  
 13 

 [Revolving Credit Agreement (2019-2B)] 

 

 
applied by the Liquidity Provider to Liquidity Obligations then due and payable in accordance with the Intercreditor Agreement and shall discharge in full the corresponding obligations of the
Borrower hereunder (or, if not provided for in the Intercreditor Agreement, then in such manner as the Liquidity Provider shall deem appropriate). 

Section 2.08    Book Entries. The Liquidity Provider shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower resulting from Advances made from time to time and the amounts of principal and interest payable hereunder and paid from time to time in respect thereof; provided,
however, that the failure by the Liquidity Provider to maintain such account or accounts shall not affect the obligations of the Borrower in respect of Advances. 

Section 2.09    Payments from Available Funds Only. All payments to be made by the Borrower under this
Agreement, including, without limitation, Sections 7.05 and 7.07, shall be made only from the amounts that constitute Scheduled Payments, Special Payments or payments under Section 8.1 of the Participation Agreements and payments under the Fee
Letter applicable to this Agreement and Section 6 of the Note Purchase Agreement and only to the extent that the Borrower shall have sufficient income or proceeds therefrom to enable the Borrower to make payments in accordance with the terms
hereof after giving effect to the priority of payments provisions set forth in the Intercreditor Agreement. The Liquidity Provider agrees that it will look solely to such amounts in respect of payments to be made by the Borrower hereunder to the
extent available for distribution to it as provided in the Intercreditor Agreement and this Agreement and that the Borrower, in its individual capacity, is not personally liable to it for any amounts payable or liability under this Agreement except
as expressly provided in this Agreement, the Intercreditor Agreement or any Participation Agreement. Amounts on deposit in the Class B Cash Collateral Account shall be available to the Borrower to make payments under this Agreement only to the
extent and for the purposes expressly contemplated in Section 3.5(f) of the Intercreditor Agreement. 

Section 2.10    Non-Extension of the Expiry Date; Non-Extension Advance. If in any calendar year the Liquidity Provider advises the Borrower before the 25th day prior to the anniversary date of the
Closing Date in such calendar year (such 25th day, the “Notice Date”) that the Expiry Date shall not be extended beyond such anniversary date (and if this Agreement shall
not have been replaced in accordance with Section 3.5(e) of the Intercreditor Agreement), the Borrower shall be entitled on and after such Notice Date (but prior to the then effective Expiry Date) to request a
Non-Extension Advance in accordance with Section 2.02(b) hereof and Section 3.5(d) of the Intercreditor Agreement; provided, however, that if in any calendar year the Liquidity Provider
does not so advise the Borrower before the Notice Date in such calendar year, the Expiry Date shall be automatically extended to the anniversary date of the Closing Date in the next calendar year. 

ARTICLE III 

OBLIGATIONS OF THE BORROWER 

Section 3.01    Increased Costs. The Borrower shall pay to the Liquidity Provider from time to time such
amounts as may be necessary to compensate the Liquidity Provider for any 

  
 14 

 [Revolving Credit Agreement (2019-2B)] 

 

 
increased costs incurred by the Liquidity Provider which are attributable to its making or maintaining any Advances hereunder or its obligation to make any such Advances hereunder, or any
reduction in any amount receivable by the Liquidity Provider under this Agreement or the Intercreditor Agreement in respect of any such Advances or such obligation (such increases in costs and reductions in amounts receivable being herein called
“Additional Costs”), resulting from any change after the date of this Agreement in U.S. federal, state, municipal, or foreign laws or regulations (including Regulation D of the Board of Governors of the Federal Reserve
System), or the adoption or making after the date of this Agreement of any interpretations, directives, or requirements applying to a class of banks including the Liquidity Provider under any U.S. federal, state, municipal, or any foreign laws or
regulations (whether or not having the force of law) by any court, central bank or monetary authority charged with the interpretation or administration thereof (a “Regulatory Change”), which: (1) changes the basis of
taxation of any amounts payable to the Liquidity Provider under this Agreement in respect of any such Advances or such obligation (other than Excluded Taxes); or (2) imposes or modifies any reserve, special deposit, compulsory loan or similar
requirements relating to any extensions of credit or other assets of, or any deposits with other liabilities of, the Liquidity Provider (including any such Advances or such obligation or any deposits referred to in the definition of LIBOR Rate or
related definitions). For the avoidance of doubt, any Regulatory Changes based on the consultative papers of The Basel Committee on Banking Supervision of December 2009 entitled “Strengthening the resilience of the banking sector” and
“International framework for liquidity risk measurement, standards and monitoring”, in each case together with any amendments thereto (collectively, “Basel III”), will not be treated, for purposes of determining
whether the Liquidity Provider is entitled to compensation under this Section 3.01, as having been adopted or having come into effect before the date hereof, and any such Regulatory Changes based on Basel III shall be determined to be adopted
only when the national banking supervisory authorities, or other relevant administrative or legislative bodies having primary jurisdiction or regulatory authority over the Liquidity Provider, adopt any such Regulatory Changes based on Basel III in
the primary jurisdiction of the Liquidity Provider. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would
avoid the need for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider. 

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.01 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts
owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.01 of the effect of any Regulatory Change on its costs of making or maintaining Advances or on amounts receivable by it in respect of Advances, and
of the additional amounts required to compensate the Liquidity Provider in respect of any Additional Costs, shall be prima facie evidence of the amount owed under this Section. 

Notwithstanding the preceding two paragraphs, the Liquidity Provider and the Subordination Agent agree that any permitted assignee or
participant of the initial Liquidity Provider which is not a bank shall not be entitled to the benefits of the preceding two paragraphs (but without limiting the provisions of Section 7.08 hereof). 

  
 15 

 [Revolving Credit Agreement (2019-2B)] 

 

 Section 3.02    Capital Adequacy and Liquidity Coverage. If
(1) the adoption, after the date hereof, of any applicable governmental law, rule or regulation regarding capital adequacy or liquidity coverage, (2) any change, after the date hereof, in the interpretation or administration of any such
law, rule or regulation by any central bank or other governmental authority charged with the interpretation or administration thereof or (3) compliance by the Liquidity Provider or any corporation or bank controlling the Liquidity Provider with
any applicable guideline or request of general applicability, issued after the date hereof, by any central bank or other governmental authority (whether or not having the force of law) that constitutes a change of the nature described in
clause (2), has the effect of (x) requiring an increase in the amount of capital or liquid assets required to be maintained by the Liquidity Provider or any corporation or bank controlling the Liquidity Provider, or (y) reducing the
rate of return on assets or capital of the Liquidity Provider (or such corporation or bank) and such adoption, change or compliance, as the case may be, relates to a category of claims or assets that includes the Liquidity Provider’s
obligations hereunder (including funded obligations) and other similar obligations, the Borrower shall, subject to the provisions of the next paragraph, pay to the Liquidity Provider from time to time such additional amount or amounts as are
necessary to compensate the Liquidity Provider for such portion of such increase or reduction as shall be reasonably allocable to the Liquidity Provider’s obligations to the Borrower hereunder. For the avoidance of doubt, the adoption of any
law, rule or regulation described in clause (1) of the first sentence of this Section 3.02, and the taking of any action described in clauses (2) and (3) of such sentence, that in each case is based on Basel III, will not be treated,
for purposes of determining whether the Liquidity Provider (or any corporation or bank controlling the Liquidity Provider) is entitled to compensation under this Section 3.02, as having been adopted, come into effect, been issued or been taken
before the date hereof, and any such law, rule or regulation and any of the actions described in clauses (2) and (3) of such sentence that is based on Basel III shall be determined to have been adopted, come into effect, been issued or been
taken only when the central bank or other legislative or administrative governmental authorities in the primary jurisdiction of the Liquidity Provider (or any corporation or bank controlling the Liquidity Provider) adopt any such law, rule or
regulation or take any such actions. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would avoid the need
for, or reduce the amount of, any amount payable under this Section that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise materially disadvantageous to the Liquidity Provider. 

The Liquidity Provider will notify the Borrower of any event occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.02 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, which notice shall describe in reasonable detail the calculation of the amounts
owed under this Section. Determinations by the Liquidity Provider for purposes of this Section 3.02 of the effect of any increase in the amount of capital or liquid assets required to be maintained by the Liquidity Provider and of the amount
allocable to the Liquidity Provider’s obligations to the Borrower hereunder shall be conclusive evidence of the amounts owed under this Section, absent manifest error. 

  
 16 

 [Revolving Credit Agreement (2019-2B)] 

 

 Notwithstanding the preceding two paragraphs, the Liquidity Provider and the Subordination
Agent agree that any permitted assignee or participant of the initial Liquidity Provider which is not a bank shall not be entitled to the benefits of the preceding two paragraphs (but without limiting the provisions of Section 7.08 hereof).

 Section 3.03    Payments Free of Deductions. (a) Unless required by applicable law, all payments
made by the Borrower under this Agreement shall be made free and clear of, and without reduction for or on account of, any present or future stamp or other taxes, levies, imposts, duties, charges, fees, deductions, withholdings, restrictions or
conditions of any nature whatsoever now or hereafter imposed on, levied, collected, withheld or assessed, excluding Excluded Taxes (such non-excluded taxes being referred to herein, collectively, as
“Non-Excluded Taxes” and each, individually, as a “Non-Excluded Tax”). If any
Non-Excluded Taxes are required to be withheld from any amounts payable to the Liquidity Provider under this Agreement, (i) the Borrower shall within the time prescribed therefor by applicable law pay to
the appropriate governmental or taxing authority the full amount of any such Non-Excluded Taxes (and any additional Non-Excluded Taxes in respect of the additional
amounts payable under clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) the amounts so payable to the Liquidity Provider shall be
increased to the extent necessary to yield to the Liquidity Provider (after payment of all Non-Excluded Taxes) interest or any other such amounts payable under this Agreement at the rates or in the amounts
specified in this Agreement. The Liquidity Provider agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Facility Office if making such change would avoid the
need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider. From time to time upon the
reasonable request of the Borrower, the Liquidity Provider agrees to provide to the Borrower two original Internal Revenue Service Forms W-8BEN-E, W-8ECI or W-9, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that the Liquidity Provider is exempt from or entitled to
a reduced rate of United States withholding tax on payments pursuant to this Agreement. Within 30 days after the date of each payment hereunder, the Borrower shall furnish to the Liquidity Provider the original or a certified copy of (or other
documentary evidence of) the payment of the Non-Excluded Taxes applicable to such payment. 

(b)    Unless required by applicable law, all payments (including, without limitation, Advances) made by the Liquidity
Provider under this Agreement shall be made free and clear of, and without reduction for or on account of, any Taxes. If any Taxes are required to be withheld or deducted from any amounts payable to the Borrower under this Agreement, the Liquidity
Provider shall (i) within the time prescribed therefor by applicable law pay to the appropriate governmental or taxing authority the full amount of any such Taxes (and any additional Taxes in respect of the additional amounts payable under
clause (ii) hereof) and make such reports or returns in connection therewith at the time or times and in the manner prescribed by applicable law, and (ii) pay to the Borrower an additional amount which (after deduction of all such Taxes)
will be sufficient to yield to the Borrower the full amount which would have been received by it had no such withholding or deduction been made. Within 30 days after the date of each payment hereunder, the Liquidity Provider shall furnish to the
Borrower the original or a certified copy of (or other documentary evidence of) the payment of the Taxes applicable to such payment. 

  
 17 

 [Revolving Credit Agreement (2019-2B)] 

 

 (c)    On or before the Closing Date, the Borrower shall provide the
Liquidity Provider with a fully executed Internal Revenue Service Form W-9, showing a complete exemption from U.S federal backup withholding tax. If any other exemption from, or reduction in the rate of, any
Taxes required to be borne by the Liquidity Provider under Section 3.03(b) is reasonably available to the Borrower without providing any information regarding the holders or beneficial owners of the Certificates, the Borrower shall deliver the
Liquidity Provider such form or forms and such other evidence of the eligibility of the Borrower for such exemption or reductions (but without any requirement to provide any information regarding the holders or beneficial owners of the Certificates)
as the Liquidity Provider may reasonably identify to the Borrower as being required as a condition to exemption from, or reduction in the rate of, such Taxes. 

(d)    If a payment made to the Liquidity Provider or Borrower hereunder would be subject to U.S. federal withholding Tax
imposed by FATCA if the Borrower or Liquidity Provider, as applicable, were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471 (b) or 1472 (b) of the U.S. Internal Revenue Code, as
applicable), it shall deliver to the Borrower or the Liquidity Provider, as applicable, at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or Liquidity Provider, as applicable, such documentation
prescribed by applicable law (including as prescribed by Section 1471 (b)(3)(C)(i) of the U.S. Internal Revenue Code) and such additional documentation reasonably requested by the Borrower or Liquidity Provider, as applicable, as may be
necessary for the Borrower or Liquidity Provider, as applicable, to comply with its obligations under FATCA and to determine that the Liquidity Provider or Borrower has complied with the Liquidity Provider’s or Borrower’s obligations under
FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this paragraph, “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 

Section 3.04    Payments. The Borrower shall make or cause to be made each payment to the Liquidity Provider
under this Agreement so as to cause the same to be received by the Liquidity Provider not later than 1:00 P.M. (New York City time) on the day when due. The Borrower shall make all such payments in lawful money of the United States of America,
to the Liquidity Provider in immediately available funds, by wire transfer to the account specified for the Liquidity Provider in Schedule B or to such other U.S. bank account as the Liquidity Provider may from time to time direct the Borrower in
writing. 
 Section 3.05    Computations. All computations of interest based on the Base Rate shall be made
on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the LIBOR Rate (other than where the LIBOR Rate is determined based on the Base Rate or any Benchmark Replacement Rate with determinations based
on a year of 365 or 366 days, as the case may be) shall be made on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is
payable. 
 Section 3.06    Payment on Non-Business Days. Whenever
any payment to be made hereunder to the Liquidity Provider shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and no additional interest shall be due as a result. If any
payment in respect of interest on an Advance is so deferred to the next succeeding Business Day, such deferral shall not delay the commencement of the next Interest 

  
 18 

 [Revolving Credit Agreement (2019-2B)] 

 

 
Period for such Advance (if such Advance is a LIBOR Advance) or reduce the number of days for which interest will be payable on such Advance on the next interest payment date for such Advance.

 Section 3.07    Interest. (a) Subject to Section 2.09, the Borrower shall pay, or shall cause
to be paid, without duplication, interest on (i) the unpaid principal amount of each Advance from and including the date of such Advance (or, in the case of an Applied Provider Advance or Applied Special Termination Advance, from and including
the date on which the amount thereof was withdrawn from the Class B Cash Collateral Account to pay interest on the Class B Certificates) to but excluding the date such principal amount shall be paid in full (or, in the case of an Applied
Provider Advance or Applied Special Termination Advance, the date on which the Class B Cash Collateral Account is fully replenished in respect of such Advance) and (ii) any other amount due hereunder (whether fees, commissions, expenses or
other amounts or, to the extent permitted by law, installments of interest on Advances or any such other amount) which is not paid when due (whether at stated maturity, by acceleration or otherwise) from and including the due date thereof to but
excluding the date such amount is paid in full, in each such case, at a fluctuating interest rate per annum for each day equal to the Applicable Liquidity Rate (as defined below) for such Advance or such other amount, as the case may be, as in
effect for such day, but in no event at a rate per annum greater than the maximum rate permitted by applicable law; provided, however, that, if at any time the otherwise applicable interest rate as set forth in this Section 3.07
shall exceed the maximum rate permitted by applicable law, then any subsequent reduction in such interest rate will not reduce the rate of interest payable pursuant to this Section 3.07 below the maximum rate permitted by applicable law until
the total amount of interest accrued equals the amount of interest that would have accrued if such otherwise applicable interest rate as set forth in this Section 3.07 had at all times been in effect. 

(b)    Except as provided in clause (e) below, each Advance will be either a Base Rate Advance or a LIBOR Advance as
provided in this Section. Each such Advance will be a Base Rate Advance for the period from the date of its Borrowing to (but excluding) the third LIBOR Business Day following the Liquidity Provider’s receipt of the Notice of Borrowing for such
Advance. Thereafter, such Advance shall be a LIBOR Advance. 
 (c)    Each LIBOR Advance shall bear interest during each
Interest Period at a rate per annum equal to the LIBOR Rate for such Interest Period plus the Applicable Margin for such LIBOR Advance, payable in arrears on the last day of such Interest Period and, in the event of the payment of principal of such
LIBOR Advance on a day other than such last day, on the date of such payment (to the extent of interest accrued on the amount of principal repaid). 

(d)    Each Base Rate Advance shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin
for such Base Rate Advance, payable in arrears on each Regular Distribution Date and, in the event of the payment of principal of such Base Rate Advance on a day other than a Regular Distribution Date, on the date of such payment (to the extent of
interest accrued on the amount of principal repaid). 
 (e)    Each outstanding Unapplied
Non-Extension Advance, Unapplied Downgrade Advance and Unapplied Special Termination Advance shall bear interest in an amount equal to the Investment Earnings on amounts on deposit in the Class B Cash
Collateral Account plus the 

  
 19 

 [Revolving Credit Agreement (2019-2B)] 

 

 
Applicable Margin for such Unapplied Non-Extension Advance, Unapplied Downgrade Advance or Unapplied Special Termination Advance, as applicable, on the
amount of such Unapplied Non-Extension Advance, Unapplied Downgrade Advance or Unapplied Special Termination Advance, as applicable, from time to time, payable in arrears on each Regular Distribution Date.

 (f)    Each amount not paid when due hereunder (whether fees, commissions, expenses or other amounts or, to the
extent permitted by applicable law, installments of interest on Advances but excluding Advances) shall bear interest at a rate per annum equal to the Base Rate plus 2.00% per annum until paid. 

(g)    If at any time, the Liquidity Provider shall have determined (which determination shall be conclusive and binding
upon the Borrower, absent manifest error) that, by reason of circumstances affecting the relevant interbank lending market generally (other than a Benchmark Replacement Event), the LIBOR Rate determined or to be determined for the current or the
immediately succeeding Interest Period will not adequately and fairly reflect the cost to the Liquidity Provider (as conclusively certified by the Liquidity Provider, absent manifest error) of making or maintaining LIBOR Advances, the Liquidity
Provider shall give facsimile or telephonic notice thereof (a “Rate Determination Notice”) to the Borrower (any such telephonic notice to be promptly confirmed in writing and transmitted by telecopier to the Borrower in
accordance with Section 7.02). If such notice is given, then the outstanding principal amount of the LIBOR Advances shall be converted to Base Rate Advances effective from the date of the Rate Determination Notice; provided that the
Applicable Liquidity Rate in respect of such Base Rate Advances shall be increased by one percent (1.00%). The Liquidity Provider shall withdraw a Rate Determination Notice given hereunder when the Liquidity Provider determines that the
circumstances giving rise to such Rate Determination Notice no longer apply to the Liquidity Provider, and the Base Rate Advances shall be converted to LIBOR Advances effective as of the first day of the next succeeding Interest Period after the
date of such withdrawal. 
 (h)    Each change in the Base Rate shall become effective immediately. The rates of
interest specified in this Section 3.07 with respect to any Advance or other amount shall be referred to as the “Applicable Liquidity Rate”. 

Section 3.08    Replacement of Borrower. From time to time and subject to the successor Borrower’s
meeting the eligibility requirements set forth in Section 6.9 of the Intercreditor Agreement applicable to the Subordination Agent, upon the effective date and time specified in a written and completed Notice of Replacement Subordination Agent
in substantially the form of Annex VI attached hereto (a “Notice of Replacement Subordination Agent”) delivered to the Liquidity Provider by the then Borrower, the successor Borrower designated therein shall be substituted
for the Borrower for all purposes hereunder. 
 Section 3.09    Funding Loss Indemnification. The Borrower
shall pay to the Liquidity Provider, upon the request of the Liquidity Provider, such amount or amounts as shall be sufficient (in the reasonable opinion of the Liquidity Provider) to compensate it for any loss, cost, or expense incurred by reason
of the liquidation or redeployment of deposits or other funds acquired by the Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of anticipated profits) incurred as a result of: 

(1)    Any repayment of a LIBOR Advance on a date other than the last day of the Interest Period for such
Advance; or 

  
 20 

 [Revolving Credit Agreement (2019-2B)] 

 

 (2)    Any failure by the Borrower to borrow a LIBOR
Advance on the date for borrowing specified in the relevant notice under Section 2.02. 
 Calculation of all amounts payable to the
Liquidity Provider under this Section 3.09 shall be made as though the Liquidity Provider had actually funded the related LIBOR Advance through the purchase of a LIBOR deposit bearing interest at the LIBOR Rate in an amount equal to its LIBOR
Advance and having a maturity comparable to the relevant Interest Period; provided, however, that the Liquidity Provider may fund any LIBOR Advance in any manner it sees fit and the foregoing assumptions shall be utilized only for the
purposes of calculating amounts payable under this Section 3.09. 
 Section 3.10    Illegality.
Notwithstanding any other provision in this Agreement, if any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by the Liquidity Provider (or its Facility Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall
make it unlawful or impossible for the Liquidity Provider (or its Facility Office) to maintain or fund its LIBOR Advances, then upon notice to the Borrower by the Liquidity Provider, the outstanding principal amount of the LIBOR Advances shall be
converted to Base Rate Advances (a) immediately upon demand of the Liquidity Provider, if such change or compliance with such request, in the judgment of the Liquidity Provider, requires immediate repayment; or (b) at the expiration of the
last Interest Period to expire before the effective date of any such change or request. The Liquidity Provider agrees to use reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the jurisdiction of its Facility
Office if making such change would avoid or cure the aforesaid illegality and would not, in the reasonable judgment of the Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.

or consent shall be effective only in the specific instance and for the specific purpose for which given. 

Section 7.02    Notices, Etc. Except as otherwise expressly provided herein, all notices and other
communications provided for hereunder shall be in writing (including telecopier and mailed or delivered or sent by telecopier) addressed to the applicable party at its address specified on Schedule B or to such other address as shall be designated

Section 7.03    No Waiver; Remedies. No failure on the part of the Liquidity Provider to exercise, and no

 25 

 [Revolving Credit Agreement (2019-2B)] 

 

 
thereof; nor shall any single or partial exercise of any right under this Agreement preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided
are cumulative and not exclusive of any remedies provided by law. 
 Section 7.04    Further Assurances. The
Borrower agrees to do such further acts and things and to execute and deliver to the Liquidity Provider such additional assignments, agreements, powers and instruments as the Liquidity Provider may reasonably require or deem advisable to carry into

shall pay on demand, all Expenses of any kind or nature whatsoever (other than any Expenses of the nature described in Section 3.01, 3.02 or 7.07 hereof or in the Fee Letter applicable to this Agreement (regardless of whether indemnified
against pursuant to said Sections or in such Fee Letter)), that may be imposed, incurred by or asserted against any Liquidity Indemnitee, in any way relating to, resulting from, or arising out of or in connection with any action, suit or proceeding
by any third party against such Liquidity Indemnitee and relating to this Agreement, the Fee Letter applicable to this Agreement, the Intercreditor Agreement or any Financing Agreement; provided, however, that the Borrower shall not be
required to indemnify, protect, defend and hold harmless any Liquidity Indemnitee in respect of any Expense of such Liquidity Indemnitee to the extent such Expense is (i) attributable to the gross negligence or willful misconduct of such
Liquidity Indemnitee or any other Liquidity Indemnitee, (ii) ordinary and usual operating overhead expense, or (iii) attributable to the failure by such Liquidity Indemnitee or any other Liquidity Indemnitee to perform or observe any
agreement, covenant or condition on its part to be performed or observed in this Agreement, the Intercreditor Agreement, the Fee Letter applicable to this Agreement or any other Operative Agreement to which it is a party. The indemnities contained
in Section 8.1 of the Participation Agreements, and the provisions of Sections 3.01, 3.02, 3.03, 3.09, 7.05 and 7.07 hereof, shall survive the termination of this Agreement.

Provider against delivery of a Notice of Borrowing and other documents which do not comply with the terms hereof; provided, however, that the Borrower shall have a claim against the Liquidity Provider, and the Liquidity Provider shall
be liable to the Borrower, to the extent of any damages suffered by the Borrower which were the result of (A) the Liquidity Provider’s willful misconduct or negligence in determining whether documents presented hereunder comply with the
terms hereof, or (B) any breach by the Liquidity Provider of any of the terms of this Agreement, including, but not limited to, the Liquidity Provider’s failure to make lawful payment hereunder after the delivery to it by the Borrower of a
Notice of Borrowing strictly 

  
 26 

 [Revolving Credit Agreement (2019-2B)] 

 

 
complying with the terms and conditions hereof. In no event, however, shall the Liquidity Provider be liable on any theory of liability for any special, indirect, consequential or punitive
damages (including, without limitation, any loss of profits, business or anticipated savings). 
 (b)    Neither the
Liquidity Provider nor any of its officers, employees, directors or Affiliates shall be liable or responsible in any respect for (i) any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice,
however transmitted, in connection with this Agreement or any Notice of Borrowing delivered hereunder, or (ii) any action, inaction or omission which may be taken by it in good faith, absent willful misconduct or gross negligence (in which

Section 7.07    Costs, Expenses and Taxes. The Borrower agrees to pay, or cause to be paid (A) on the
Effective Date and on such later date or dates on which the Liquidity Provider shall make demand, all reasonable out-of-pocket costs and expenses (including, without
limitation, the reasonable fees and expenses of outside counsel for the Liquidity Provider) of the Liquidity Provider in connection with the preparation, negotiation, execution, delivery, filing and recording of this Agreement, any other Operative
Agreement and any other documents which may be delivered in connection with this Agreement and (B) on demand, all reasonable costs and expenses (including reasonable counsel fees and expenses) of the Liquidity Provider in connection with
(i) the enforcement of this Agreement or any other Operative Agreement, (ii) the modification or amendment of, or supplement to, this Agreement or any other Operative Agreement or such other documents which may be delivered in connection
herewith or therewith (whether or not the same shall become effective) or any waiver or consent thereunder (whether or not the same shall be effective), (iii) the replacement of this Agreement by a Replacement Liquidity Facility pursuant to
Section 3.5(e)(i) of the Intercreditor Agreement or (iv) any action or proceeding relating to any order, injunction, or other process or decree restraining or seeking to restrain the Liquidity Provider from paying any amount under this
Agreement, the Intercreditor Agreement or any other Operative Agreement or otherwise affecting the application of funds in the Class B Cash Collateral Account. In addition, the Borrower shall pay any and all recording, stamp and other similar
taxes and fees payable or determined to be payable in connection with the execution, delivery, filing and recording of this Agreement, any other Operative Agreement and such other documents, and agrees to hold the Liquidity Provider harmless from
and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such taxes or fees. 

Section 7.08    Binding Effect; Participations. (a) This Agreement shall be binding upon and inure to the
benefit of the Borrower and the Liquidity Provider and their respective successors and assigns, except that neither the Liquidity Provider (except as otherwise provided in this Section 7.08 and in Section 3.5(l) of the Intercreditor
Agreement) nor (except as contemplated by Section 3.08) the Borrower shall have the right to assign its rights or obligations hereunder or any interest herein without the prior written consent of the other party, subject to the requirements of
Section 7.08(b). The Liquidity Provider may grant participations herein or in any of its rights hereunder (including, without limitation, funded participations and participations in rights to receive interest payments hereunder) and under the
other Operative Agreements to such Persons (other than United and its Affiliates) as the Liquidity Provider may in its sole 

  
 27 

 [Revolving Credit Agreement (2019-2B)] 

 

 
discretion select, subject to the requirements of Section 7.08(b). No such granting of participations by the Liquidity Provider, however, will relieve the Liquidity Provider of its
obligations hereunder. In connection with any participation or any proposed participation, the Liquidity Provider may disclose to the participant or the proposed participant any information that the Borrower is required to deliver or to disclose to
the Liquidity Provider pursuant to this Agreement. The Borrower acknowledges and agrees that the Liquidity Provider’s source of funds may derive in part from its participants. Accordingly, references in this Agreement and the other Operative
Agreements to determinations, reserve, capital adequacy and liquidity coverage requirements, increased costs, reduced receipts, additional amounts due pursuant to Section 3.03 and the like as they pertain to the Liquidity Provider shall be
deemed also to include those of each of its participants that are banks (subject, in each case, to the maximum amount that would have been incurred by or attributable to the Liquidity Provider directly if the Liquidity Provider, rather than the
participant, had held the interest participated). 
 (b)    If, pursuant to subsection (a) above, the Liquidity
Provider sells any participation in this Agreement to any bank or other entity (each, a “Transferee”), then, concurrently with the effectiveness of such participation, the Transferee shall (i) represent to the Liquidity
Provider (for the benefit of the Liquidity Provider and the Borrower) either (A) that it is incorporated under the laws of the United States or a state thereof or (B) that under applicable law and treaties, no taxes will be required to be
withheld with respect to any payments to be made to such Transferee in respect of this Agreement, (ii) furnish to the Liquidity Provider and the Borrower either (x) a statement that it is incorporated under the laws of the United States or
a state thereof or (y) if it is not so incorporated, two copies of a properly completed United States Internal Revenue Service Form W-8ECI, Form W-8BEN-E or Form W-9, as appropriate, or other applicable form, certificate or document prescribed by the Internal Revenue Service certifying, in each case, such
Transferee’s entitlement to a complete exemption from United States federal withholding tax in respect to any and all payments to be made hereunder, and (iii) agree (for the benefit of the Liquidity Provider and the Borrower) to provide
the Liquidity Provider and the Borrower a new Form W-8ECI, Form W-8BEN-E or Form W-9, as
appropriate, (A) on or before the date that any such form expires or becomes obsolete or (B) after the occurrence of any event requiring a change in the most recent form previously delivered by it and prior to the immediately following due
date of any payment by the Borrower hereunder, certifying in the case of a Form W-8ECI, Form W-8BEN-E or Form W-9 that such Transferee is entitled to a complete exemption from United States federal withholding tax on payments under this Agreement. Unless the Borrower has received forms or other documents reasonably
satisfactory to it (and required by applicable law) indicating that payments hereunder are not subject to United States federal withholding tax, the Borrower will withhold taxes as required by law from such payments at the applicable statutory rate.

 (c)    Notwithstanding the other provisions of this Section 7.08, the Liquidity Provider may assign and pledge
all or any portion of the Advances owing to it to any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by
such Federal Reserve Bank, provided that any payment in respect of such assigned Advances made by the Borrower to the Liquidity Provider in accordance with the terms of this Agreement shall satisfy the Borrower’s obligations hereunder in
respect of such assigned Advance to the extent of such payment. No such assignment shall release the Liquidity Provider from its obligations hereunder.

 Section 7.09    Severability. Any provision of this Agreement

registered or certified mail (or any substantially similar form of mail), postage prepaid, to each party hereto at its address set forth in Section 7.02 hereof, or at such other address of which the Liquidity Provider shall have been notified
pursuant thereto; and 
 (iv)    agrees that nothing herein shall affect the right to effect service of process in any
other manner permitted by law or shall limit the right to sue in any other jurisdiction. 
 (b)    THE BORROWER AND THE
LIQUIDITY PROVIDER EACH HEREBY AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE
RELATIONSHIP THAT IS BEING ESTABLISHED, including, without limitation, contract claims, tort claims, breach of duty claims and all other common law and statutory claims. The Borrower and the Liquidity Provider each warrant and represent that it has
reviewed this waiver with its legal counsel, and that it knowingly and voluntarily waives its jury trial rights following consultation with such legal counsel. THIS WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS
WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT. 

  
 29

 (c)    To the extent that the Liquidity Provider or any of its properties
has or may hereafter acquire any right of immunity, whether characterized as sovereign immunity or otherwise, and whether under the United States Foreign Sovereign Immunities Act of 1976 (or any successor legislation) or otherwise, from any legal
proceedings, whether in the United States or elsewhere, to enforce or collect upon this Agreement, including, without limitation, immunity from suit or service of process, immunity from jurisdiction or judgment of any court or tribunal or execution
of a judgment, or immunity of any of its property from attachment prior to any entry of judgment, or from attachment in aid of execution upon a judgment, the Liquidity Provider hereby irrevocably and expressly waives any such immunity, and agrees
not to assert any such right or claim in any such proceeding, whether in the United States or elsewhere. 

Section 7.12    Execution in Counterparts. This Agreement may be executed in any number of counterparts and by

Section 7.13    Entirety. This Agreement, the Intercreditor Agreement and the other Operative Agreements to
which the Liquidity Provider is a party constitute the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior understandings and agreements of such parties.

act) be deemed to have assumed all of the Class B Trustee’s rights, title, interest and obligations in, to and under this Agreement, and, thereafter, each reference to the Borrower herein and in the other Operative Agreements shall be
deemed a reference to the trustee of the Successor Trust.
