 AMOUNT AND TERMS OF THE COMMITMENT 

Section 2.01 The Advances. The Liquidity Provider hereby irrevocably 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 12:00 noon (New York City time) on the Expiry Date (unless the obligations of the Liquidity Provider shall be earlier terminated in
accordance with the terms of Section 2.04(b)) in an aggregate amount at any time outstanding not to exceed the Maximum Commitment. 

Section 2.02 Making of Advances. (a) Subject to Section 2.06(d), each Interest Advance shall be made by the Liquidity
Provider upon delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex I, signed by a Responsible Officer of the Borrower, such Interest Advance to be in an amount not exceeding the
Maximum Available Commitment at such time and used solely for the payment when due of interest with respect to the Class B Certificates at the Stated Interest Rate therefor in accordance with Section 3.05(a) and 3.05(b) 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 an amount equal to the amount of such Interest Advance so repaid, 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) both a Performing Note Deficiency exists and a Liquidity Event of Default shall have occurred and be continuing or (y) a Final Advance, a Downgrade Advance, a Non-Extension Advance
or a Special Termination Advance shall have occurred. 
 (b) (i) A Non-Extension Advance shall be made by the Liquidity Provider if this
Agreement is not extended in accordance with Section 3.05(d) of the Intercreditor Agreement unless a Replacement Liquidity Facility to replace this Agreement shall have been previously delivered to the Borrower in accordance with said

 (ii) A Downgrade Advance shall be made by the Liquidity Provider if this Liquidity Facility
becomes a Downgraded Facility (as provided for in Section 3.05(c) of the Intercreditor Agreement) unless within 35 days of such Downgrade Event (i) a Replacement Liquidity Facility to replace this Agreement shall have been previously
delivered to the Borrower in accordance with said Section 3.05(c) of the Intercreditor Agreement, or (ii) the relevant Rating Agency shall have provided a written confirmation to the effect that the occurrence of such Downgrade Event will
not result in the downgrading, withdrawal or suspension by such Rating Agency of the ratings then issued by such Rating Agency for the Class B Certificates, by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in
substantially the form of Annex III, 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 3.05(c) and 3.05(f) of the Intercreditor Agreement. 
 (c) A Final Advance shall be made by the Liquidity Provider following the
receipt by the Borrower of a Termination Notice from the Liquidity Provider pursuant to Section 6.01(a) upon delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex IV, 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 3.05(f) and 3.05(i) of the Intercreditor
Agreement. 
 (d) 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 6.01(b), by delivery to the Liquidity Provider of a written and completed Notice of Borrowing in substantially the form of Annex V, 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 3.05(f) and Section 3.05(k) of the Intercreditor Agreement. 

(e) Each Borrowing shall be made by notice in writing (a “Notice of Borrowing”) in substantially the form required by
Section 2.02(a), 2.02(b), 2.02(c) or 2.02(d), 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 12:30 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 such requested Borrowing, the Liquidity Provider shall make available to the Borrower, in accordance with its payment instructions, the
amount of such Borrowing in Dollars and immediately available funds, before 4:00 p.m. (New York City time) on such Business Day or before 12:30 p.m. (New York City time) on such later Business Day specified in such Notice of Borrowing. If a Notice

Liquidity

		 		 	Revolving Credit Agreement (Class B)
		 		 	(American Airlines 2021-1 EETC)

 
Provider shall make available to the Borrower, in accordance with its payment instructions, the amount of such Borrowing in Dollars and immediately available funds, before 1:00 p.m. (New York
City time) on the first Business Day next following the day of receipt of such Notice of Borrowing or on such later Business Day specified by the Borrower in 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 delivery of a copy thereof to the Liquidity Provider at the address and in the manner specified in Section 7.02 hereof. 

(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 (including the Class B Trustee or any Class B Certificateholder). 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), 2.02(c) or 2.02(d) 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, 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 3.05(c)(v), 3.05(e) or 3.05(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 2.02(b) of the Intercreditor Agreement. By 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. 

Section 2.03 Fees. The Borrower agrees to pay to the Liquidity Provider the fees set forth in the Fee Letter. 

Section 2.04 Reduction 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). The Borrower shall give notice of any such automatic reduction of the Maximum Commitment to the Liquidity Provider and American within two Business Days thereof. The failure by the Borrower to furnish any such notice shall not
affect any such automatic reduction of the Maximum Commitment.

		 		 	(American Airlines 2021-1 EETC)

 (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 (a) 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 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 in the amounts and on the dates determined as provided in Section 3.07; 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 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 3.05(f) of the Intercreditor Agreement (the portion of the outstanding Special Termination Advance equal to the amount of any such withdrawal, but not in excess of the outstanding Special Termination Advance, 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(a), such Special Termination Advance
(including any portion thereof that is an Applied Special Termination Advance) shall thereafter be treated as a Final Advance under this Agreement for purposes of determining the Applicable Liquidity Rate for interest payable thereon; and,
provided, further, that if, after making a Provider Advance, the Liquidity Provider delivers a Special Termination Notice to the Borrower pursuant to Section 6.01(b), 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, 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. For the avoidance of doubt, interest payable on an Interest Advance, Special Termination Advance or the Final Advance shall not be regarded as overdue unless such interest is not paid when due under Section 3.07.

hereunder in respect of a Provider Advance shall be deposited in the Class B Cash Collateral Account and invested and withdrawn from the Class B Cash Collateral Account as set forth in Sections 3.05(c), 3.05(d), 3.05(e) and 3.05(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, in the amounts determined 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 3.05(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; 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(a), such Provider Advance shall thereafter be treated as a Final Advance under this Agreement for purposes
of determining the Applicable Liquidity Rate for interest payable thereon. Subject to Sections 2.07 and 2.09, 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 such reduction, plus interest on the principal amount so repaid as provided in Section 3.07. 

(b) At any time when an Applied Provider Advance or 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 3.02 of the Intercreditor Agreement (any such amount being a “Replenishment Amount”) for the purpose of
replenishing or increasing the balance thereof up to the Required Amount at such time, (i) the aggregate outstanding principal amount of all Applied Provider Advances and Applied Special Termination Advances (and of Provider Advances and
Special Termination Advances treated as Interest Advances for purposes of determining the Applicable Liquidity Rate for interest payable thereon) shall be automatically reduced by the amount of such Replenishment Amount, and (ii) the aggregate
outstanding principal amount of all Unapplied Provider Advances 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 3.05(e) of the
Intercreditor Agreement, as provided in Section 3.05(f) 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 Liquidity Provider, but only to the extent such amounts are necessary to repay in full to the Liquidity Provider all amounts owing to it hereunder.

		 		 	(American Airlines 2021-1 EETC)

 (d) If, at any time after making a Downgrade Advance, the Liquidity Provider satisfies the
Threshold Rating and delivers written notice to that effect to the Borrower and American, as of the second Business Day following receipt of such notice, (i) this Liquidity Facility shall cease to be a Downgraded Facility, (ii) any
Unapplied Downgrade Advance shall be withdrawn from the Class B Cash Collateral Account and reimbursed to the Liquidity Provider, (iii) any Applied Downgrade Advance shall be converted to an Interest Advance, (iv) the Maximum Available
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, (v) the Borrower shall be entitled to request Borrowings and (vi) the proviso in the definition of Maximum Available Commitment and the proviso in the final sentence of Section 2.02(a) shall, in each case, 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 3.05(f) of the Intercreditor Agreement), shall be paid to the Liquidity Provider in accordance with the terms thereof (but, for the
avoidance of doubt, without duplication of or increase in any amounts payable hereunder). Amounts so paid to the Liquidity Provider shall be applied by the Liquidity Provider in the order of priority required by the applicable provisions of Articles
II and III of the Intercreditor Agreement and shall discharge in full the corresponding obligations of the Borrower hereunder. 

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 shall be made only
from the amounts that constitute Scheduled Payments, Special Payments and other payments under the Operative Agreements, including payment under Section 4.02 of the Participation Agreements and payments under Section 2.14 of the
Indentures, 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 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 3.05(f) of the Intercreditor Agreement.

Date”) that its obligation to make Advances hereunder shall not be extended beyond the immediately following anniversary date of the Closing Date (and if the Liquidity Provider shall not have been replaced in accordance with

Section 3.05(d) of the Intercreditor Agreement. 
 Section 2.11 LIBOR Replacement. Notwithstanding anything to the contrary

USD LIBOR’s administrator (“IBA”), announced in a public statement the future cessation or loss of representativeness of overnight/Spot Next, 1-month, 3-month, 6-month and 12-month USD LIBOR tenor settings. On the earlier of
(i) the date that all Available Tenors of the USD LIBOR have either permanently or indefinitely ceased to be provided by IBA or have been announced by the FCA pursuant to public statement or publication of information to be no longer
representative and (ii) the Early Opt-in Effective Date, if the then-current Benchmark is the LIBOR Rate, the Benchmark Replacement will replace such Benchmark for all purposes hereunder in respect of any setting of such Benchmark on such day
and all subsequent settings without any amendment to, or further action or consent of any other party to this Agreement. If the Benchmark Replacement is Daily Simple SOFR, all interest payments will be payable on a monthly basis. 

(b) Upon the occurrence of a Benchmark Transition Event, the Benchmark Replacement will replace the then current Benchmark for all purposes
hereunder in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Borrower by the Liquidity Provider without any
amendment to, or further action or consent of any other party to this Agreement, or further action or consent of the Borrower or any other Person, so long as the Liquidity Provider has not received, by such time, written notice of objection to such
Benchmark Replacement from the Borrower. 
 (c) In connection with the implementation of a Benchmark Replacement, the Liquidity Provider will
have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any
further action or consent of the Borrower or any other party hereto. 
 (d) The Liquidity Provider will promptly notify the Borrower and the
Class B Trustee of (i) the implementation of any Benchmark Replacement and (ii) the effectiveness of any Benchmark Replacement Conforming Changes. Any determination, decision or election that may be made by the Liquidity Provider pursuant
to this Section 2.11, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be
conclusive and binding absent manifest error and may be made in its sole discretion and without consent from the Borrower or any other party hereto, except, in each case, as expressly required pursuant to this Section.

		 		 	(American Airlines 2021-1 EETC)

 (e) At any time (including in connection with the implementation of a Benchmark
Replacement), (i) if the then-current Benchmark is a term rate (including Term SOFR or USD LIBOR), then the Liquidity Provider may remove any tenor of such Benchmark that is unavailable or non-representative for Benchmark (including Benchmark
Replacement) settings and (ii) the Liquidity Provider may reinstate any such previously removed tenor for Benchmark (including Benchmark Replacement) settings. 

(f) As used in this Section 2.11, the following terms have the following meanings: 

“Available Tenor” means, as of any date of determination and with respect to the then-current Benchmark, as applicable,
(x) if the then-current Benchmark is a term rate, any tenor for such Benchmark that is or may be used for determining the length of an Interest Period or (y) otherwise, any payment period for interest calculated with reference to such
Benchmark, as applicable, pursuant to this Agreement as of such date. 
 “Benchmark” means, initially, the LIBOR Rate;
provided that if a replacement of the Benchmark has occurred pursuant to this Section 2.11, then “Benchmark” means the applicable Benchmark Replacement to the extent that such Benchmark Replacement has replaced such prior benchmark
rate. Any reference to “Benchmark” shall include, as applicable, the published component used in the calculation thereof. 

“Benchmark Replacement” means, for any Available Tenor: 

(1) For purposes of clause (a) of this Section 2.11, the first alternative set forth below that can be determined by
the Liquidity Provider: 
 (a) the sum of: (i) Term SOFR and (ii) 0.11448% (11.448 basis points) for an Available Tenor of
one-month’s duration, 0.26161% (26.161 basis points) for an Available Tenor of three-months’ duration, and 0.42826% (42.826 basis points) for an Available Tenor of six-months’ duration, or 

(b) the sum of: (i) Daily Simple SOFR and (ii) the spread adjustment recommended by the Relevant Governmental Body for the
replacement of the tenor of the LIBOR Rate with a SOFR-based rate having approximately the same length as the interest payment period specified in clause (a) of this Section 2.11; and; 

(2) For purposes of clause (b) of this Section 2.11, the sum of (a) the alternate benchmark rate and (b) an
adjustment (which may be a positive or negative value or zero), in each case, that has been selected by the Liquidity Provider as the replacement for such Available Tenor of such Benchmark giving due consideration to any evolving or then-prevailing
market convention, including any applicable recommendations made by the Relevant Governmental Body, for U.S. dollar-denominated syndicated or bilateral credit facilities at such time;

		 		 	(American Airlines 2021-1 EETC)

operational changes (including changes to the definition of “Business Day”, the definition of “Interest Period”, timing and frequency of determining rates and making payments of interest, timing of borrowing requests or
prepayment, conversion or continuation notices, the applicability and length of lookback periods, the applicability of breakage provisions, and other technical, administrative or operational matters) that the Liquidity Provider decides may be
appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by the Liquidity Provider in a manner substantially consistent with market practice (or, if the Liquidity Provider decides
that adoption of any portion of such market practice is not administratively feasible or if the Liquidity Provider determines that no market practice for the administration of such Benchmark Replacement exists, in such other manner of administration

authority with jurisdiction over the administrator for such Benchmark or a court or an entity with similar insolvency or resolution authority over the administrator for such Benchmark, announcing or stating that (a) such administrator has
ceased or will cease on a specified date to provide all Available Tenors of such Benchmark, permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide
any Available Tenor of such Benchmark or (b) all Available Tenors of such Benchmark are or will no longer be representative of the underlying market and economic reality that such Benchmark is intended to measure and that representativeness
will not be restored. 
 “Daily Simple SOFR” means, for any day, SOFR, with the conventions for this rate (which will
include a lookback) being established by the Liquidity Provider in accordance with the conventions for this rate recommended by the Relevant Governmental Body for determining “Daily Simple SOFR” for business loans; provided, that if the
Liquidity Provider decides that any such convention is not administratively feasible for it, then the Liquidity Provider may establish another convention in its reasonable discretion. 

“Early Opt-in Effective Date” means, with respect to any Early Opt-in Election, the sixth (6th) Business Day after the
date notice of such Early Opt-in Election is provided to the Borrower, so long as the Liquidity Provider has not received, by 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Early Opt-in Election is
provided to the Borrower, written notice of objection to such Early Opt-in Election from the Borrower.

credit facilities are identified in the notice to the Borrower described in clause (2) below and are publicly available for review), and 

(2) the election by the Liquidity Provider to trigger a fallback from the LIBOR Rate and the provision by the Liquidity
Provider of written notice of such election to any other party hereto.

overnight financing rate identified as such by the administrator of the secured overnight financing rate from time to time).

 ARTICLE III 
 OBLIGATIONS OF
THE BORROWER 
 Section 3.01 Increased Costs. Without duplication of any rights created by Section 3.03, if as a result of any
Regulatory Change there shall be any increase by an amount reasonably deemed by the Liquidity Provider to be material in the actual cost to the Liquidity Provider of making, funding or maintaining any Advances or its obligation to make any such
Advances or there shall be any reduction by an amount reasonably deemed by the Liquidity Provider to be material in the amount receivable by the Liquidity Provider under this Agreement or the Intercreditor Agreement in respect thereof, and in case
of either such an increase or reduction, such event does not arise from the gross negligence or willful misconduct of the Liquidity 

  

					
		 	20	 	
		 		 	Revolving Credit Agreement (Class B)
		 		 	(American Airlines 2021-1 EETC)

 
Provider, from its breach of any of its representations, warranties, covenants or agreements contained herein or in the Intercreditor Agreement or from its failure to comply with any such
Regulatory Change (any such increase or reduction being referred to herein as an “Increased Cost”), then, subject to Sections 2.07 and 2.09, the Borrower shall from time to time pay to the Liquidity Provider an amount equal
to such Increased Cost within 10 Business Days after delivery to the Borrower and American of a certificate of an officer of the Liquidity Provider describing in reasonable detail the event by reason of which it claims such Increased Cost and the
basis for the determination of the amount of such Increased Cost; provided that the Borrower shall be obligated to pay amounts only with respect to any Increased Costs accruing from the date 120 days prior to the date of delivery of such
certificate. Such certificate, in the absence of manifest error, shall be considered prima facie evidence of the amount of the Increased Costs for purposes of this Agreement; provided that any determinations and allocations by the Liquidity
Provider of the effect of any Regulatory Change on the costs of maintaining the Advances or the obligation to make Advances are made on a reasonable basis. For the avoidance of doubt, the Liquidity Provider shall not be entitled to assert any claim
under this Section 3.01 in respect of or attributable to Excluded Taxes. The Liquidity Provider will notify the Borrower and American as promptly as practicable of any event occurring after the date of this Agreement that will entitle the
Liquidity Provider to compensation under this Section 3.01. The Liquidity Provider agrees to investigate all commercially reasonable alternatives for reducing any Increased Costs and to use all commercially reasonable efforts to avoid or
minimize, to the greatest extent possible, any claim in respect of Increased Costs, including, without limitation, by designating a different Lending Office, if such designation or other action would avoid the need for, or reduce the amount of, any
such claim; provided that the foregoing shall not obligate the Liquidity Provider to take any action that would, in its reasonable judgment, cause the Liquidity Provider to take any action that is not materially consistent with its internal
policies or is otherwise materially disadvantageous to the Liquidity Provider or that would cause the Liquidity Provider to incur any material loss or cost, unless the Borrower or American agrees to reimburse or indemnify the Liquidity Provider
therefor. If no such designation or other action is effected, or, if effected, such notice fails to avoid the need for any claim in respect of Increased Costs, American may arrange for a Replacement Liquidity Facility in accordance with
Section 3.05(e) of the Intercreditor Agreement. 
 Notwithstanding the foregoing provisions, in no event shall the Borrower be required
to make payments under this Section 3.01: (a) in respect of any Regulatory Change proposed by any applicable governmental authority (including any branch of a legislature), central bank or comparable agency of the United States or the
Liquidity Provider’s jurisdiction of organization or in which its Lending Office is located and pending as of the date of this Agreement (it being agreed that the Regulatory Changes contemplated by (i) all requests, rules, guidelines or
directives promulgated or issued by the Basel Committee on Banking Supervision (or any successor or similar authority) including, but not limited to the Consultative Documents entitled “Strengthening the resilience of the banking sector”
and “International framework for liquidity risk measurement, standards and monitoring,” each dated December 2009 or the United States regulatory authorities, in each case pursuant to Basel III and (ii) the Dodd-Frank Wall Street
Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder or issued in connection therewith, shall not be considered to have been proposed or pending as of the date of this Agreement); (b) if a claim
hereunder in respect of an Increased Cost arises 

  

					
		 	21	 	
		 		 	Revolving Credit Agreement (Class B)
		 		 	(American Airlines 2021-1 EETC)

 
through circumstances peculiar to the Liquidity Provider and that do not affect similarly organized commercial banking institutions in the same jurisdiction generally that are in compliance with
the law, rule, regulation or interpretation giving rise to the Regulatory Change relating to such Increased Cost; (c) if the Liquidity Provider shall fail to comply with its obligations under this Section 3.01 or (d) if the Liquidity
Provider is not also seeking payment for similar increased costs in other similarly situated transactions related to the airline industry. 

Section 3.02 Intentionally omitted. 

Section 3.03 Withholding Taxes. (a) All payments made by the Borrower under this Agreement shall be made without deduction or
withholding for or on account of any Taxes, unless such deduction or withholding is required by law. If any Taxes are so required to be withheld or deducted from any amounts payable to the Liquidity Provider under this Agreement, then, subject to
Sections 2.07 and 2.09, the Borrower shall (i) deduct or withhold and shall pay to the relevant authorities the full amount so required to be deducted or withheld, (ii) without duplication of any rights created by Section 3.01, if
such Taxes are Covered Taxes, pay to the Liquidity Provider such additional amounts as shall be necessary to ensure that the net amount actually received by the Liquidity Provider (after deduction or withholding of all Covered Taxes) shall be equal
to the full amount that would have been received by the Liquidity Provider had no withholding or deduction of Covered Taxes been required and (iii) within 30 days after the date of a payment to the relevant authorities furnish to the Liquidity
Provider the original or a certified copy of (or other reasonable evidence of) the payment of the Taxes applicable to such payment. The Borrower agrees to indemnify the Liquidity Provider, within 10 Business Days of demand therefor the full amount
of Covered Taxes paid or payable by the Liquidity Provider in respect of payments by the Borrower under this Agreement and any reasonable expenses arising therefrom or with respect thereto. If the Borrower provides a written request (which shall be
considered prior written consent under subsection (vi) of the definition of Covered Taxes), the Liquidity Provider agrees to use commercially reasonable efforts (consistent with applicable legal and regulatory restrictions) to change the
jurisdiction of its Lending 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
materially disadvantageous to the Liquidity Provider. If the Liquidity Provider receives a refund of, or realizes a net Tax benefit not otherwise available to it as a result of, any Taxes for which additional amounts were paid by the Borrower
pursuant to this Section 3.03, the Liquidity Provider shall pay to the Borrower (for deposit into the Collection Account) the amount of such refund (and any interest thereon), net of any related out-of-pocket expenses, or net benefit. The
Borrower, upon the request of the Liquidity Provider, shall repay to the Liquidity Provider the amount paid over pursuant to this paragraph (a) (plus any penalties, interest or other charges imposed by the relevant governmental or taxing
authority) in the event that the Liquidity Provider is required to repay such refund to such governmental or taxing authority. Notwithstanding anything to the contrary in this paragraph (a), in no event will the Liquidity Provider be required to pay
any amount to the Borrower pursuant to this paragraph (a) the payment of which would place the Liquidity Provider in a less favorable net after-Tax position than the Liquidity Provider would have been in if the Tax subject to indemnification
and giving rise to such refund or net Tax benefit had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph (a) shall not be
construed to require the Liquidity Provider to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the Borrower or any other Person. 

  

					
		 	22	 	
		 		 	Revolving Credit Agreement (Class B)
		 		 	(American Airlines 2021-1 EETC)

 The Liquidity Provider will (i) provide (on its behalf and on behalf of any participant
holding a Participation pursuant to Section 7.08) to the Borrower (x) on or prior to the Effective Date two valid completed and executed originals of Internal Revenue Service Form W-9, W-8BEN-E or W-8ECI (whichever is applicable),
including thereon a valid United States taxpayer identification number (or, with respect to any such participant, such other form or documentation as may be applicable) covering all amounts receivable by it in connection with the transactions
contemplated by the Operative Agreements and (y) thereafter from time to time such additional forms or documentation as may be necessary to establish an available exemption from withholding of United States Tax on payments hereunder so that
such forms or documentation are effective for all periods during which it is the Liquidity Provider and (ii) provide timely notice to the Borrower if any such form or documentation is or becomes inaccurate. The Liquidity Provider shall deliver
to the Borrower such other forms or documents as may be reasonably requested by the Borrower or required by applicable law to establish that payments hereunder are exempt from or entitled to a reduced rate of Covered Taxes. 

If a payment made to the Liquidity Provider or Borrower hereunder would be subject to United States 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 United States 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 United States 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. 

(b) 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. 

  

					
		 	23	 	
		 		 	Revolving Credit Agreement (Class B)
		 		 	(American Airlines 2021-1 EETC)

 On or before the Closing Date, the Borrower shall provide the Liquidity Provider with its
fully executed Internal Revenue Service Form W-9, showing a complete exemption from United States federal withholding tax and backup withholding. If any other exemption from, or reduction in the rate of, any Taxes required to be borne by the
Liquidity Provider under this 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. 

Section 3.04 Payments. Subject to Sections 2.07 and 2.09, 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 Dollars, to the Liquidity
Provider in immediately available funds, by wire transfer to the account set forth below or such other United States bank account as the Liquidity Provider may from time to time direct the Subordination Agent:

 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 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 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 (and if so made, shall be deemed to
have been made when due). 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 Sections 2.07 and 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 

  

					
		 	24	 	
		 		 	Revolving Credit Agreement (Class B)
		 		 	(American Airlines 2021-1 EETC)

 
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), to the extent permitted by law, any other amount due hereunder (whether fees, commissions, expenses or other amounts or installments of interest on
Advances or any such other amount) that 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 the interest
rate per annum for each day that such amount remains overdue and unpaid equal to the Applicable Liquidity Rate for such Advance or such other amount, as the case may be, as in effect for such day, but in no event in any case referred to in clause
(i) or (ii) above 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 to the maximum extent permitted by applicable law 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 absolute amount of interest that would have accrued (without additional interest thereon) if such otherwise applicable interest rate as set forth in this
Section 3.07 had at all relevant times been in effect. 
 (b) Except as provided in Section 3.07(e), each Advance will be either a
Base Rate Advance or a LIBOR Advance as provided in this Section 3.07. Each such Advance will be a Base Rate Advance for the period from the date of its Borrowing to (but excluding) the third Business Day following the Liquidity Provider’s
receipt of the Notice of Borrowing for such Advance. Thereafter, such Advance shall be a LIBOR Advance; provided that an Applied Provider Advance and an Applied Special Termination Advance shall be a LIBOR Advance from the date of its
withdrawal from the Class B Cash Collateral Account. 
 (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 (each, an
“Unapplied Advance”), as the case may be, shall bear interest, payable in arrears on each Regular Distribution Date, in an amount equal to the sum of (i) the Investment Earnings on amounts on deposit in the Class B Cash
Collateral Account on account of such Unapplied Advance during the period beginning on the later of the date of deposit of such Unapplied Advance and the preceding Regular Distribution Date and ending on the last day prior to such Regular
Distribution Date and (ii) an amount equal to interest at the Applicable Margin on the amount of such Unapplied Advance during such period.

		 		 	Revolving Credit Agreement (Class B)
		 		 	(American Airlines 2021-1 EETC)

 (f) Each amount not paid when due hereunder (whether fees, commissions, expenses or other
amounts or installments of interest on Advances but excluding Advances) shall bear interest, to the extent permitted by applicable law, at a rate per annum equal to the Base Rate plus 2.0% 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 the occurrence of a Benchmark Transition Event as addressed in Section 2.11), the LIBOR Rate determined or to be
determined for the next 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 Advances, the
Liquidity Provider shall give facsimile or telephonic notice thereof (a “Rate Determination Notice”) to the Borrower and American. 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. 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. Subject to Section 5.02, from time to time and subject to the successor Borrower’s
meeting the eligibility requirements set forth in Section 6.09 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 VIII (a “Notice of Replacement Subordination Agent”) delivered to the Liquidity Provider by the then Borrower, the successor Borrower designated therein shall become 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 the Applicable Margin or 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 

(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.

		 		 	Revolving Credit Agreement (Class B)
		 		 	(American Airlines 2021-1 EETC)

 Section 3.10 Illegality. Notwithstanding any other provision in this Agreement,
if any change in any law, rule or regulation applicable to or binding on the Liquidity Provider, 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 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 to maintain or fund its LIBOR Advances, then upon notice to the Borrower and American 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 reasonable judgment of the Liquidity Provider, requires immediate conversion; 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 will notify the Borrower and American as promptly as practicable of any event that will or to its knowledge is reasonably likely to lead to the
conversion of LIBOR Advances to Base Rate Advances under this Section 3.10; provided that a failure by the Liquidity Provider to notify the Borrower or American of an event that is reasonably likely to lead to such a conversion prior to
the time that it is determined that such event will lead to such a conversion shall not prejudice the rights of the Liquidity Provider under this Section 3.10. The Liquidity Provider agrees to investigate all commercially reasonable
alternatives for avoiding the need for such conversion, including, without limitation, designating a different Lending Office, if such designation or other action would avoid the need to convert such LIBOR Advances to Base Rate Advances;
provided that the foregoing shall not obligate the Liquidity Provider to take any action that would, in its reasonable judgment, cause the Liquidity Provider to incur any material loss or cost, unless the Borrower or American agrees to
reimburse or indemnify the Liquidity Provider therefor. If no such designation or other action is effected, or, if effected, fails to avoid the need for conversion of the LIBOR Advances to Base Rate Advances, American may arrange for a Replacement
Liquidity Facility in accordance with Section 3.05(e) of the Intercreditor Agreement.

conditions are satisfied with respect to any Participation, the Liquidity Provider may grant such Participation): (i) such Participation is to a Permitted Transferee, (ii) such Participation is made in accordance

  

					
		 	33	 	
		 		 	Revolving Credit Agreement (Class B)
		 		 	(American Airlines 2021-1 EETC)

 
with all applicable laws, including, without limitation, the Securities Act of 1933, as amended, the Trust Indenture Act of 1939, as amended, any laws or regulations imposing United States
economic sanctions measures or any orders or licenses issued thereunder and any other applicable laws relating to the transfer of similar interests and (iii) such Participation shall not be made under circumstances that require registration
under the Securities Act of 1933, as amended, or qualification of any indenture under the Trust Indenture Act of 1939, as amended. Notwithstanding any such Participation, the Liquidity Provider agrees that (1) the Liquidity Provider’s
obligations under the Operative Agreements shall remain unchanged, and such participant shall have no rights or benefits as against American or the Borrower or under any Operative Agreement, (2) the Liquidity Provider shall remain solely
responsible to the other parties to the Operative Agreements for the performance of such obligations, (3) the Liquidity Provider shall remain the maker of any Advances, and the other parties to the Operative Agreements shall continue to deal
solely and directly with the Liquidity Provider in connection with the Advances and the Liquidity Provider’s rights and obligations under the Operative Agreements, (4) the Liquidity Provider shall be solely responsible for any withholding
Taxes or any filing or reporting requirements relating to such Participation and shall hold the Borrower and American and their respective successors, permitted assigns, affiliates, agents and servants harmless against the same and (5) neither
American nor the Borrower shall be required to pay to the Liquidity Provider any amount under Section 3.01 or Section 3.03 greater than it would have been required to pay had there not been any grant of a Participation by the Liquidity
Provider. The Liquidity Provider may, in connection with any Participation or proposed Participation pursuant to this Section 7.08(b), disclose to the participant or proposed participant any information relating to the Operative Agreements or
to the parties thereto furnished to the Liquidity Provider thereunder or in connection therewith and permitted to be disclosed by the Liquidity Provider; provided, however, that prior to any such disclosure, the participant or proposed
participant shall agree in writing for the express benefit of the Borrower and American to preserve the confidentiality of any confidential information included therein (subject to customary exceptions). The Borrower acknowledges and agrees that the
Liquidity Provider’s source of funds may derive in part from its participants. Accordingly, in determining amounts due by the Borrower to the Liquidity Provider pursuant to Section 3.01 and Section 3.03 of this Agreement, references
in this Agreement to determinations, reserve, liquidity and capital adequacy 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 commercial banking institutions and of whose participation the Borrower has been notified, in each case up to the maximum amount that would have been incurred by or attributable to the
Liquidity Provider directly had there not been any grant of a Participation by the Liquidity Provider, and references to the Liquidity Provider therein and in related definitions shall be treated as references to such participants where applicable;
provided that in any event, neither American nor the Borrower shall be required to pay any amount under Section 3.01 or Section 3.03 greater than it would have been required to pay had there not been any grant of a Participation by
the Liquidity Provider. If the Liquidity Provider sells a Participation, it shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each participant and the principal amounts
(and stated interest) of each participant’s interest in this Agreement.

from the transactions contemplated by the Operative Agreements, (ii) furnish to the Liquidity Provider and the Borrower two properly completed executed originals of 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 participant’s entitlement to a complete exemption from United States federal withholding tax and backup
withholding for all income derived by it from the transactions contemplated by the Operative Agreements, (iii) agree (for the benefit of the Liquidity Provider and the Borrower) to provide each of the Liquidity Provider and the Borrower a new
Form W-8ECI, Form W-8BEN-E or Form W-9, as appropriate, or other applicable form, certificate or document (A) on or before the date that any such form, certificate or document expires or becomes obsolete or (B) after the occurrence of any
event requiring a change in the most recent form, certificate or document previously delivered by it and prior to the immediately following due date of any payment to be made to the participant pursuant to the Operative Agreements, certifying that
such participant is entitled to a complete exemption from or reduction in United States federal withholding tax and backup withholding for all income derived by it from the transactions contemplated by the Operative Agreements or that it is no
longer so entitled and (iv) agree (for the benefit of the Liquidity Provider and the Borrower) to provide such other forms or documents as may be reasonably requested by the Borrower or required by applicable law to establish that all income
derived by it from the transactions contemplated by the Operative Agreements is exempt from or entitled to a reduced rate of Covered Taxes. The Liquidity Provider shall provide to the Borrower such information as the Borrower may reasonably request
about the Liquidity Provider or a participant to satisfy any reporting or other Tax obligations of the Borrower with respect to this Agreement; provided that the Liquidity Provider shall not be required to provide any such information (other
than the names of participants, percentage of participation and copies of such participants’ withholding tax forms) which is not within its possession or which is confidential. 

(d) 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. To the extent permitted by applicable law, any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

 WHEREAS, the
Original Indenture provides that by means of a supplemental indenture, the Issuer may create one or more series of its debt securities and establish the form and terms and conditions thereof. 

WHEREAS, the Issuer intends by this Twentieth Supplemental Indenture to (i) create a series of debt securities, in an initial

 NOW, THEREFORE IT IS AGREED: 

ARTICLE ONE 

Definitions, Creation, Form and Terms and Conditions of the Debt Securities 

SECTION 1.01. Definitions. Capitalized terms used in this Twentieth Supplemental Indenture and not otherwise defined shall have
the meanings ascribed to them in the Original Indenture. In addition, the following terms shall have the following meanings to be equally applicable to both the singular and the plural forms of the terms defined: 

“DTC” means The Depository Trust Company. 

“Electronic Means” means the following communications methods: e-mail,
facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection
with its services hereunder. 

  
 1 

 “Global Note” means a single fully-registered global note in book-entry
form, without coupons, substantially in the form of Exhibit A attached hereto. 
 “Indenture” means the Original
Indenture as supplemented by this Twentieth Supplemental Indenture. 
 “Make-Whole Amount” means, in connection with any
optional redemption or accelerated payment of any Note, the excess, if any, of (i) the aggregate present value as of the date of such redemption or accelerated payment of each dollar of principal being redeemed or paid and the amount of
interest (exclusive of interest accrued to the date of redemption or accelerated payment) that would have been payable in respect of each such dollar through October 15, 2031, if such redemption or accelerated payment had been made on
October 15, 2031, determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (determined on the third Business Day preceding the date such notice of redemption is given or declaration of acceleration
is made) from the respective dates on which such principal and interest would have been payable if such redemption or accelerated payment had been made on October 15, 2031, over (ii) the aggregate principal amount of the Notes being
redeemed or paid. 
 “Notes” means the Issuer’s 2.250% Senior Notes due January 15, 2032, a form of which is
attached hereto as Exhibit A. 
 “Redemption Price” means the sum of (i) the principal amount of the Notes

October 15, 2031, the Redemption Price shall mean the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date without any payment of a Make-Whole Amount. The Redemption Price
shall be calculated by the Issuer or such other party appointed by the Issuer. 
 “Reinvestment Rate” means 0.150% plus the
arithmetic mean of the yields under the respective heading “Week Ending” published in the most recent Statistical Release under the caption “Treasury Constant Maturities” for the maturity (rounded to the nearest month)
corresponding to the remaining life to maturity (which maturity shall be deemed to be October 15, 2031), as of the payment date of the principal being redeemed or paid. If no maturity exactly corresponds to such maturity, yields for the two
published maturities most closely corresponding to such maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding
in each of such relevant periods to the nearest month. For the purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used. 

“Statistical Release” means the statistical release designated “H.15” or any successor publication which is
published weekly by the Federal Reserve System and which establishes yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any determination
under the Indenture, then such other reasonably comparable index which shall be designated by the Issuer. 

  
 2 

 SECTION 1.02. Creation of the Debt Securities. In accordance with
Section 301 of the Original Indenture, the Issuer hereby creates the Notes as a separate series of its debt securities issued pursuant to the Indenture. The Notes shall be issued in an aggregate principal amount initially limited to
$500,000,000. 
 The Issuer may issue, in addition to the Notes originally issued on the date hereof, additional Notes, so long as such
additional Notes are fungible for U.S. federal income tax purposes with the Notes. The Notes originally issued on the date hereof and any additional Notes originally issued subsequent to the date hereof shall be a single series for all purposes
under the Original Indenture. 
 SECTION 1.03. Form of the Debt Securities. The Notes will be represented by a single
fully-registered global note in book-entry form, without coupons, registered in the name of the nominee of DTC. The Notes shall be in the form of Exhibit A attached hereto. So long as DTC, or its nominee, is the registered owner of a Global
Note, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the notes represented by such Global Note for all purposes under the Indenture. Ownership of beneficial interests in the Global Note will be shown on, and
transfers thereof will be effected only through, records maintained by DTC (with respect to beneficial interests of participants) or by participants or persons that hold interests through participants (with respect to beneficial interests of
beneficial owners). 
 SECTION 1.04. Terms and Conditions of the Debt Securities. The Notes shall be governed by all the terms
and conditions of the Original Indenture, as supplemented and modified by this Twentieth Supplemental Indenture, and in particular, the following provisions shall be terms of the Notes: 

(a) Optional Redemption. The Issuer may redeem the Notes at any time at the option of the Issuer, in whole or from time to time in
part, at a redemption price equal to the Redemption Price. 
 If notice has been given as provided in the Original Indenture and funds for
the redemption of any Notes called for redemption shall have been made available on the Redemption Date referred to in such notice, such Notes will cease to bear interest on the date fixed for such redemption specified in such notice and the only
right of the Holders of the Notes will be to receive payment of the Redemption Price. 
 Notice of any optional redemption of any Notes will
be given to Holders at their addresses, as shown in the Security Register, not more than 60 nor less than 15 days prior to the date fixed for redemption. The notice of redemption will specify, among other items, the Redemption Price and the
principal amount of the Notes held by such Holder to be redeemed. 
 If less than all the Notes are to be redeemed at the option of the
Issuer, the Issuer will notify the Trustee at least 45 days prior to giving notice of redemption (or such shorter period as is satisfactory to the Trustee) of the aggregate principal amount of Notes to be redeemed and their Redemption Date. The
Trustee shall select, in such manner as it shall deem fair and appropriate, no less than 45 days prior to the Redemption Date and in accordance with applicable depositary procedures, the Notes to be redeemed in part. 

  
 3 

 (b) Payment of Principal and Interest. Principal and interest payments on interests
represented by a Global Note will be made to DTC or its nominee, as the case may be, as the registered owner of such Global Note. All payments of principal and interest in respect of the Notes will be made by the Issuer in immediately available
funds. 
 (c) Applicability of Defeasance or Covenant Defeasance. The provisions of Article 14 of the Original Indenture shall apply
to the Notes. 
 (d) Definition of Total Unencumbered Assets. For purposes of the covenants entitled “Limitations on Incurrence
of Debt” and “Maintenance of Total Unencumbered Assets” in Sections 1004 and 1005 of the Original Indenture, the following terms shall be defined, solely with respect to the Notes, as follows: 

(i) “Debt” of the Issuer or any Subsidiary means any indebtedness of the Issuer or any Subsidiary, whether or not
contingent, in respect of (i) borrowed money evidenced by bonds, notes, debentures or similar instruments, (ii) indebtedness secured by any mortgage, pledge, lien, charge, encumbrance or any security interest existing on property owned by
the Issuer or any Subsidiary, (iii) the reimbursement obligations, contingent or otherwise, in connection with any letters of credit actually issued or amounts representing the balance deferred and unpaid of the purchase price of any property
except any such balance that constitutes an accrued expense or trade payable or (iv) any lease of property by the Issuer or any Subsidiary as lessee which is reflected on the Issuer’s consolidated balance sheet as a financing lease in
accordance with GAAP, in the case of items of indebtedness under (i) through (iii) above to the extent that any such items (other than letters of credit) would appear as a liability on the Issuer’s consolidated balance sheet in accordance
with GAAP, and also includes, to the extent not otherwise included, any obligation by the Issuer or any Subsidiary to be liable for, or to pay, as obligor, guarantor or otherwise (other than for purposes of collection in the ordinary course of
business), indebtedness of another person (other than the Issuer or any Subsidiary) (it being understood that Debt shall be deemed to be incurred by the Issuer and its Subsidiaries on a consolidated basis whenever the Issuer and its Subsidiaries on
a consolidated basis shall create, assume, guarantee or otherwise become liable in respect thereof). 
 (ii) “Total
Assets” as of any date means the sum of (i) the Undepreciated Real Estate Assets and (ii) all other assets of the Issuer and its Subsidiaries on a consolidated basis determined in accordance with GAAP (but excluding non-real estate intangibles, operating lease assets and accounts receivable). 
 (iii)
“Total Unencumbered Assets” means the sum of (i) those Undepreciated Real Estate Assets not subject to an encumbrance and (ii) all other assets of the Issuer and its Subsidiaries not subject to an encumbrance determined in
accordance with GAAP (but excluding non-real estate intangibles, operating lease assets and accounts receivable); provided, however, that all investments by the Issuer and its Subsidiaries in unconsolidated
joint ventures, unconsolidated limited partnerships, unconsolidated limited liability companies and other unconsolidated entities shall be excluded from the calculation of Total Unencumbered Assets to the extent that such investments would have
otherwise been included. 

  
 4 

 (iv) “Undepreciated Real Estate Assets” means as of any date the
cost (original cost plus capital improvements) of real estate assets of the Issuer and its Subsidiaries on such date, before depreciation and amortization, determined on a consolidated basis in accordance with GAAP. 

(e) Cross-Acceleration. For purposes of the Event of Default provided for in Section 501(5) of the Original Indenture, all
references to the amount of $5,000,000 shall be increased to $50,000,000; provided, however, that for so long as any of the securities issued pursuant to any supplemental indenture to the Original Indenture that preceded this Twentieth Supplemental
Indenture are outstanding and provide for this same Event of Default but for a lower amount of such recourse debt, the reference to $50,000,000 in this paragraph is replaced by such lower amount. 

ARTICLE TWO 
 Trustee

 SECTION 2.01. Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity
or sufficiency of this Twentieth Supplemental Indenture or the due execution thereof by the Issuer. The recitals of fact contained herein shall be taken as the statements solely of the Issuer, and the Trustee assumes no responsibility for the
correctness thereof. The Trustee shall be entitled to make any withholding or deduction from payments under the Indenture to the extent necessary to comply with Sections 1471 through 1474 of the U.S. Internal Revenue Code and the rules and
regulations thereunder (as in effect from time to time). 
 SECTION 2.02. Electronic Communications. The Trustee shall have
the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Issuer shall provide to the Trustee an
incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Issuer
whenever a person is to be added or deleted from the listing. If the Issuer elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of
such Instructions shall be deemed controlling. The Issuer understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to
have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Issuer shall be responsible for ensuring that only Authorized Officers transmit such Instructions to
the Trustee and that the Issuer and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Issuer. The Trustee
shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and 

  
 5 

 
compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Issuer agrees: (i) to assume all risks arising out
of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully
informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Issuer; (iii) that
the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee
immediately upon learning of any compromise or unauthorized use of the security procedures. 
 ARTICLE THREE 

Miscellaneous Provisions 

SECTION 3.01. Ratification of Original Indenture. This Twentieth Supplemental Indenture is executed and shall be construed as an
indenture supplemental to the Original Indenture, and as supplemented and modified hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Twentieth Supplemental Indenture shall be read, taken
and construed as one and the same instrument. Notwithstanding anything herein to the contrary, to the extent any provision of this Twentieth Supplemental Indenture is inconsistent with any provision of the Original Indenture, the terms of this
Twentieth Supplemental Indenture shall govern and apply to the Notes. 
 SECTION 3.02. Effect of Headings. The Article and
Section headings herein are for convenience only and shall not affect the construction hereof. 
 SECTION 3.03. Successors and
Assigns. All covenants and agreements in this Twentieth Supplemental Indenture by the Issuer shall bind its successors and assigns, whether so expressed or not.

shall for any reason be held to be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

laws of the State of New York. This Twentieth Supplemental Indenture is subject to the provisions of the Trust Indenture Act of 1939, as amended, that are required to be part of this Twentieth Supplemental Indenture and shall, to the extent
applicable, be governed by such provisions.

 6 

 SECTION 3.07. Execution, Authentication and Delivery. The words
“execution,” “signed,” “signature,” and words of like import in the Indenture shall include images of manually executed signatures transmitted by facsimile, email or other electronic format (including, without
limitation, “pdf,” “tif” or “jpg”) and other electronic signatures (including without limitation, DocuSign and AdobeSign). The use of electronic signatures and electronic records (including, without limitation, any
contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system
to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation,
any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code. Without limitation to the foregoing, and anything in the Indenture to the contrary notwithstanding, (a) any Officers’ Certificate, Issuer Order,
Opinion of Counsel, Security, Note, certificate of authentication appearing on or attached to any Security or Note, any supplemental indenture or other certificate, instrument, agreement or other document delivered pursuant to the Indenture may be

 DUKE REALTY LIMITED PARTNERSHIP 

2.250% Senior Notes due 2032 

Duke Realty Limited Partnership, an Indiana limited partnership (the “Issuer,” which term includes any successor under the Indenture
hereinafter referred to), for value received, hereby promises to pay to Cede & Co. or its registered assigns, the principal sum of Five Hundred Million Dollars on January 15, 2032 (the “Maturity Date”), and to pay interest
thereon from and including November 10, 2021 (or from the most recent interest payment date to which interest has been paid or duly provided for) in U.S. dollars semi-annually in arrears on January 15 and July 15 of each year, each,
an “Interest Payment Date,” commencing on January 15, 2022, and on the Maturity Date, at the rate of 2.250% per annum, until payment of said principal sum has been made or duly provided for. 

 The interest so payable and punctually paid or duly provided for on any Interest Payment
Date and on the Maturity Date will be paid to the Holder in whose name this Note (or one or more predecessor Notes) is registered at the close of business on the “Record Date” for such payment, which will be 15 days (regardless of whether
such day is a Business Day (as defined below)) prior to such payment date or the Maturity Date, as the case may be. Any interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Record Date, and
shall be paid to the Holder in whose name this Note (or one or more predecessor Notes) is registered at the close of business on a subsequent Record Date for the payment of such defaulted interest (which shall be not less than five Business Days (as
defined below) prior to the date of the payment of such defaulted interest) established by notice given by mail by or on behalf of the Issuer to the Holders of the Notes not less than 15 days preceding such subsequent Record Date. Interest on this
Note will be computed on the basis of a 360-day year of twelve 30-day months. 

The principal of this Note payable on the Maturity Date will be paid against presentation and surrender of this Note at the office or agency
of the Issuer maintained for that purpose. The Issuer hereby initially designates the Corporate Trust Office of the Trustee at Global Corporate Trust, 2 N. LaSalle Street, Suite 700, Chicago, Illinois 60602 as the office to be maintained by it where
Notes may be presented for payment, registration of transfer, or exchange and where notices or demands to or upon the Issuer in respect of the Notes or the Indenture referred to on the reverse hereof may be served. 

Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest
accrued from and including the immediately preceding Interest Payment Date (or from and including November 10, 2021, in the case of the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date,
as the case may be. If any Interest Payment Date or the Maturity Date falls on a day that is not a Business Day (as defined below), the required payment of interest or principal or both, as the case may be, will be made on the next Business Day with
the same force and effect as if it were made on the date such payment was due and no interest will accrue on the amount so payable for the period from and after such Interest Payment Date or the Maturity Date, as the case may be. “Business
Day” means any day, other than a Saturday or a Sunday, on which banking institutions in The City of New York are open for business. 

Payments of principal and interest in respect of this Note will be made by wire transfer of immediately available funds in such coin or
currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts. 
 Reference
is made to the further provisions of this Note set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place. 

This Note shall not be entitled to the benefits of the Indenture referred to on the reverse hereof or be valid or become obligatory for any
purpose until the certificate of authentication hereon shall have been signed by the Trustee under such Indenture. 

 IN WITNESS WHEREOF, the Issuer has caused this instrument to be signed manually or by
facsimile by its authorized officers.

 REVERSE OF NOTE 

DUKE REALTY LIMITED PARTNERSHIP 

2.250% Senior Notes due 2032 

This security is one of a duly authorized issue of debentures, notes, bonds, or other evidences of indebtedness of the Issuer (hereinafter
called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture dated as of July 28, 2006 (hereinafter called the “Indenture”), duly executed and delivered by the
Issuer to The Bank of New York Mellon Trust Company, N.A. (as successor to J.P. Morgan Trust Company, National Association), as Trustee (hereinafter called the “Trustee,” which term includes any successor trustee under the Indenture with
respect to the series of Securities of which this Note is a part), to which the Indenture and all indentures supplemental thereto relating to this security reference is hereby made for a description of the rights, limitations of rights, obligations,
duties, and immunities thereunder of the Trustee, the Issuer, and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. The Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), and may otherwise vary as provided in
the Indenture or any indenture supplemental thereto. This security is one of a series designated as the 2.250% Senior Notes due 2032 of the Issuer, initially limited in aggregate principal amount to $500,000,000. 

In case an Event of Default with respect to this security shall have occurred and be continuing, the principal hereof and Make-Whole Amount,
if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect, and subject to the conditions provided in the Indenture. 

The Issuer may redeem this security at any time at the option of the Issuer, in whole or in part, at a redemption price equal to the sum of
(i) the principal amount of this security being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date, and (ii) the Make-Whole Amount, if any, with respect to this security (the “Redemption
Price”); provided, however, that if the Redemption Date is any time on or after October 15, 2031, the Redemption Price shall mean the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding,
the Redemption Date without any payment of a Make-Whole Amount. Notice of any optional redemption of any Securities will be given to Holders at their addresses, as shown in the Security Register, not more than 60 days nor less than 15 days prior to
the date fixed for redemption. The notice of redemption will specify, among other items, the Redemption Price and the principal amount of the Securities held by such Holder to be redeemed. 

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the Holders of not less than a majority of the
aggregate principal amount of the Securities at the time outstanding of all series to be affected (voting as one class), evidenced as provided in the Indenture, to execute supplemental indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the Holders of the Securities of each series; provided, however, that no such supplemental indenture shall, without the
consent of the Holder of each Security so affected, (i) change 

 
the Stated Maturity of the principal of (or premium, if any, on) or any installment of principal of or interest on, any Security, or reduce the principal amount thereof or the rate or amount of
interest thereon or any premium payable upon the redemption thereof, or adversely affect any right of repayment at the option of the Holder of any Security, or change any Place of Payment where, or the currency or currencies, currency unit or units
or composite currency or currencies in which, any Security or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof, or (ii) reduce
the aforesaid percentage of Securities, the Holders of which are required to consent to any such supplemental indenture, or (iii) reduce the percentage of Securities, the Holders of which are required to consent to any waiver of compliance with
certain provisions of the Indenture or any waiver of certain defaults thereunder. It is also provided in the Indenture that, with respect to certain defaults or Events of Default regarding the Securities of any series, the Holders of a majority in
aggregate principal amount outstanding of the Securities of such series (or, in the case of certain defaults or Events of Default, all series of Securities) may on behalf of the Holders of all the Securities of such series (or all of the Securities,
as the case may be) waive any such past default or Event of Default and its consequences, prior to any declaration accelerating the maturity of such Securities, or, subject to certain conditions, may rescind a declaration of acceleration and its
consequences with respect to such Securities. Any such consent or waiver by the Holder of this security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of the
security and any securities that may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this security or such other securities. 

No reference herein to the Indenture and no provision of this security or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and any Make-Whole Amount and interest on this security in the manner, at the respective times, at the rate and in the coin or currency herein prescribed. 

This security is issuable only in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000
in excess thereof. Securities may be exchanged for a like aggregate principal amount of securities of this series of other authorized denominations at the office or agency of the Issuer, in the manner and subject to the limitations provided in the
Indenture, but without the payment of any service charge except for any tax or other governmental charge imposed in connection therewith. 

Upon due presentment for registration of transfer of Securities at the office or agency of the Issuer, one or more new Securities of the same
series of authorized denominations in an equal aggregate principal amount will be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge
imposed in connection therewith. 
 The Issuer, the Trustee or any authorized agent of the Issuer or the Trustee may deem and treat the
Person in whose name this security is registered as the absolute owner of this security (whether or not this security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of,
or on account of, the principal hereof and Make-Whole Amount, if any, and subject to the provisions on the face hereof, interest hereon, and for all other purposes, and neither the Issuer nor the Trustee nor any authorized agent of the Issuer or the
Trustee shall be affected by any notice to the contrary. 

 The Indenture and each Security shall be deemed to be a contract under the laws of the State
of New York, and for all purposes shall be construed in accordance with the laws of such state, except as may otherwise be required by mandatory provisions of law. 

Capitalized terms used herein which are not otherwise defined shall have the respective meanings assigned to them in the Indenture and all
indentures supplemental thereto relating to this security.
