Re:    Suspension of Services and Payments
 
Ladies and Gentlemen:
 
Reference is made to the Services and Investment Agreement, dated as of March 31, 2015, by and among Energy Strategic Advisory Services LLC, a Delaware limited liability company (“ESAS”), and EXCO Resources, Inc., a Texas corporation (“EXCO”), as amended by the Acknowledgement of Amendment dated as of May 26, 2015 and by Amendment No. 2 dated as of September 8, 2015 (as the same may be amended or amended and restated from time to time in accordance with its terms, the “Services and Investment Agreement”), and the Letter Agreement Regarding Nomination of Designee to the Board of Directors of EXCO, dated September 8, 2015, between ESAS and EXCO (as the same may be amended or amended and restated from time to time in accordance with its terms, the “Nomination Agreement”).  All capitalized terms used but not otherwise defined herein shall have the respective meanings set forth in the Services and Investment Agreement.

Wilder’s Resignation

As we have discussed, Wilder intends to resign from the Board of Directors of EXCO and from his position as Executive Chairman of EXCO (the effective time of such resignation is referred to herein as the “Effective Time”).

Suspension of Services and Payments

ESAS and EXCO agree that, during the Suspension Period (as defined below), (i) ESAS shall not be required to provide any Services pursuant to the Services and Investment Agreement, and ESAS’ obligations to provide such Services shall be suspended, (ii) EXCO shall not be required to pay any Monthly Fee or any Incentive Payment in respect of the Suspension Period, and EXCO’s obligations to make such payments shall be suspended, and (iii) ESAS shall not have the right or obligation to nominate any person for election to the Board of Directors of EXCO, and ESAS’ and EXCO’s rights and obligations under the Nomination Agreement shall be suspended.  EXCO agrees 

that it shall pay the Monthly Fee for all periods prior to the commencement of the Suspension Period in accordance with the Services and Investment Agreement.

For purposes of this letter agreement, “Suspension Period” shall mean the period that begins at the Effective Time and ends on the date that EXCO provides written notice to ESAS that EXCO elects to have ESAS recommence provision of the Services; provided however, that if EXCO commences chapter 11 proceedings, the Suspension period shall end on the earlier of the date that (i) EXCO provides written notice to ESAS after entry of a Comfort Order (as defined below) that EXCO elects to have ESAS recommence provision of the Services and (ii) the effective date of a plan of reorganization with respect to EXCO that has been confirmed by a bankruptcy court.

For purposes of this letter agreement, a “Comfort Order” is an order entered by a bankruptcy court that provides that neither ESAS nor its Affiliates nor their respective representatives will be considered “insiders” of EXCO as a result of ESAS’ provision of the Services pursuant to the Services and Investment Agreement at EXCO’s election during the Suspension Period.

Warrants

ESAS and EXCO hereby agree that, effective as of the Effective Time, the four Warrants dated March 31, 2015 issued by EXCO to ESAS pursuant to the Services and Investment Agreement shall be forfeited and cancelled and EXCO shall have no further obligations under the Warrants.

Comfort Order

EXCO shall use its reasonable best efforts to procure a Comfort Order as expeditiously as possible after the commencement of chapter 11 proceedings, if any, with respect to EXCO and EXCO requests ESAS to recommence the provision of the Services.

Affirmation of Services and Investment Agreement

ESAS and EXCO agree that the Services and Investment Agreement and the Nomination Agreement are in full force and effect and that neither ESAS nor EXCO is in breach thereunder.  Except as expressly modified herein, all of the terms and conditions of the Services and Investment Agreement and the Nomination Agreement shall remain in full force and effect.  EXCO agrees that it will not terminate the Services and Investment Agreement or the Nomination Agreement during the Suspension Period.  

Miscellaneous

ESAS represents and warrants to EXCO that this letter agreement has been duly and validly authorized by ESAS.  EXCO represents and warrants to ESAS that this letter agreement has been duly and validly authorized by the independent members of the Board of Directors of EXCO.  This letter agreement shall be governed by, and construed in accordance with, the laws of the State of Texas without regard to principles of conflicts of law.  The terms of this letter agreement may not 

2

be amended, modified or supplemented, and waivers or consents to departures from the terms hereof may not be given, except by the written consent of all of the parties hereto.  This letter agreement may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts together shall constitute one and the same instrument.

 [REVERSE OF FORM OF 2021 NOTE] 

THE AES CORPORATION 
 4.000%
SENIOR NOTE DUE 2021 
 1.    Interest. THE AES CORPORATION, a Delaware corporation (the
“Company,” which definition shall include any successor thereto in accordance with the Indenture (as defined below)), promises to pay, until the principal hereof is paid or made available for payment, interest on the principal
amount set forth on the reverse side hereof at a rate of 4.000% per annum. Interest on the Notes will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid, from March 15, 2018
through but excluding the date on which interest is paid. Interest shall be payable in arrears on March 15 and September 15 of each year (each an “Interest Payment Date”), commencing September 15, 2018. Interest will
be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the Notes is not a Business Day, then
payment of the interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. 

2.    Method of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who
are registered Holders of Notes at the close of business on each March 1 and September 1 immediately preceding each Interest Payment Date (each, a “Regular Record Date”). Holders must surrender Notes to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. At the Company’s option, interest may be paid by check
sent to the registered address of the Holder of this Note. 
 3.    Paying Agent and Registrar. Initially,
Deutsche Bank Trust Company Americas (the “Trustee”) will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co-Registrar without notice. 

4.    Indenture. The Company issued the Notes under an Indenture dated as of December 8, 1998 between the
Company and the Trustee as supplemented by the Ninth Supplemental Indenture dated as of April 3, 2003 and the Twenty-Second Supplemental Indenture dated as of March 15, 2018 between the Company and the Trustee (said Indenture, as so
supplemented, the “Indenture”). This Note is one of an issue of Securities of the Company issued under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) as amended from time to time. The Notes are subject to all such terms, and Holders of the Notes are referred to the Indenture and such Act for a statement of them. Capitalized
terms used herein and not otherwise defined have the meanings set forth in the Indenture. The Notes are general unsecured and unsubordinated obligations of the Company ranking pari passu with all of the Company’s unsecured and unsubordinated
obligations. The Company may, subject to the terms of the Indenture and applicable law, issue Additional Notes  

  
 A-1-3 

 
under the Twenty-Second Supplemental Indenture. The Notes issued on March 15, 2018 and any Additional Notes subsequently issued shall be treated as a single class for all purposes of the
Twenty-Second Supplemental Indenture. The Indenture limits the ability of the Company to incur certain secured indebtedness and to enter into certain sale and leaseback transactions. 

5.    Optional Redemption.  

At any time prior to March 15, 2021, the Company may redeem all or a part of the Notes, on any one or more occasions, at a redemption
price equal to 100% of the principal amount of Notes to be redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the redemption date, subject to the rights of holders of record of the Notes on
the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the redemption date. Calculation of the Applicable Premium is the responsibility of the Company, and the Trustee shall have no duty
to calculate or verify the calculation of the Applicable Premium. Such redemption may, at the Company’s discretion, be subject to one or more conditions precedent. 

“Applicable Premium” means, with respect to any Note on any redemption date, the excess, if any, of (i) the present
value on such redemption date of all required remaining scheduled interest payments due on such Note (excluding accrued but unpaid interest, if any, to, but not including, the redemption date) computed using a discount rate equal to the Treasury
Rate as of such redemption date plus 50 basis points, over (ii) the principal amount of such Note. 
 “Comparable Treasury
Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the maturity date of the Notes that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities of comparable maturity. 
 “Comparable Treasury
Price” means, with respect to any redemption date: (a) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day preceding such
redemption date, as set forth in the most recently published statistical release designated “H.15 (519)” (or any successor release) published by the Board of Governors of the Federal Reserve System and which establishes yields on actively
traded United States treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” or (b) if such release (or any successor release) is not published or does not contain such prices on such
Business Day, the average of the Reference Treasury Dealer Quotations for such redemption date. 
 “Disqualified Capital
Stock” means that portion of any Capital Stock that, by its terms (or by the terms of any security into which it is convertible or for which it is exchangeable at the option of the holder thereof), or upon the happening of any event (other
than an event which would constitute a Change of Control), matures or is mandatorily redeemable, pursuant to a sinking fund obligation or otherwise, or is redeemable at the sole option of the holder thereof (except, in each case, upon the occurrence
of a Change of Control) on or prior to the date 91 days after the final maturity date of the Notes. 

  
 A-1-4 

 “Equity Interests” means Capital Stock and all warrants, options or other rights
to acquire Capital Stock (but excluding any debt security that is convertible into, or exchangeable for, Capital Stock). 
 “Equity
Offering” means a public or private sale of Equity Interests of the Company (other than Disqualified Capital Stock and other than to a Subsidiary of the Company) by the Company. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company. 

“Reference Treasury Dealer” means Morgan Stanley & Co. LLC plus two other Primary Treasury Dealers (as defined
below) selected by the Company; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall
substitute therefor another Primary Treasury Dealer. 
 “Reference Treasury Dealer Quotations” means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day preceding such redemption date. 

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the yield to maturity of the
Comparable Treasury Issue, compounded semi-annually, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. 

6.    Change of Control Offer. Upon the occurrence of a Change of Control Triggering Event, the Company shall be
required, as and to the extent set forth in the Indenture, to offer to purchase all of the outstanding Notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to, but not including,
the date of repurchase (subject to the right of the Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the repurchase date). 

7.    Sinking Fund. No sinking fund is provided for the Notes. 

8.    Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of
$2,000 and integral multiples of $1,000 thereafter. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to
pay to it any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Notes or portion of a Note selected for redemption, or transfer or exchange any Notes for a period of 15 days before
selection of such Notes to be redeemed. 

  
 A-1-5 

 9.    Persons Deemed Owners. The registered holder of a Note may be
treated as the owner of it for all purposes. 
 10.    Unclaimed Money. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an
“abandoned property” law designates another Person. 
 11.    Amendment, Supplement, Waiver. The
Company and the Trustee may, without the consent of the holders of any outstanding Notes, amend, waive or supplement the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or
inconsistencies, maintaining the qualification of the Indenture under the Trust Indenture Act of 1939 or making any other change that does not adversely affect the rights of any Holder in any material respect. Other amendments and modifications of
the Indenture or the Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of the outstanding Securities of all series affected, subject to certain exceptions
requiring the consent of the Holders of the particular Securities. 
 12.    Successor Corporation. When a
successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture and the transaction complies with the terms of Article 5 of the Senior Indenture, the predecessor corporation, subject to certain exceptions, will
be released from those obligations. 
 13.    Defaults and Remedies. Events of Default are set forth in the
Indenture. Subject to certain limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Section 6.1(d) or (e) of the Senior Indenture with respect to the Company) occurs and is continuing, then the
holders of not less than 25% in aggregate principal amount of the outstanding Notes may, or the Trustee may, by written notice to the Company, and the Trustee at the request of not less than 25% in aggregate principal amount of the outstanding Notes
will, declare the principal of, plus accrued interest, if any, to be due and payable immediately. If an Event of Default specified in Section 6.1(d) or (e) of the Senior Indenture with respect to the Company occurs and is continuing, the
Principal of and accrued interest on all of the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of the Notes may not enforce the Indenture or the
Notes except as provided in the Indenture. The Trustee may require indemnity reasonably satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then
outstanding Securities of all series issued under the Indenture that are affected may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing default (except a default in
payment of principal or interest) if it determines in good faith that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee. 

14.    Trustee Dealing with Company. The Trustee, in its individual or any other capacity, may make loans to,
accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee. 

  
 A-1-6 

 15.    No Recourse Against Others. A director, officer, employee,
stockholder or beneficiary, as such, of the Company shall not have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each
Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes. 

16.    Defeasance. The Indenture contains provisions (which provisions apply to this Note) for defeasance at any
time of (a) the entire indebtedness of the Company in respect of this Note and (b) certain restrictive covenants and Defaults and Events of Default, in each case upon compliance by the Company with certain conditions set forth therein.

 [REVERSE OF FORM OF 2023 NOTE] 

THE AES CORPORATION 
 4.500%
SENIOR NOTE DUE 2023 
 1.    Interest. THE AES CORPORATION, a Delaware corporation (the
“Company,” which definition shall include any successor thereto in accordance with the Indenture (as defined below)), promises to pay, until the principal hereof is paid or made available for payment, interest on the principal
amount set forth on the reverse side hereof at a rate of 4.500% per annum. Interest on the Notes will accrue from and including the most recent date to which interest has been paid or, if no interest has been paid, from March 15, 2018
through but excluding the date on which interest is paid. Interest shall be payable in arrears on March 15 and September 15 of each year (each an “Interest Payment Date”), commencing September 15, 2018. Interest will
be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the Notes is not a Business Day, then
payment of the interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. 

2.    Method of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who
are registered Holders of Notes at the close of business on each March 1 and September 1 immediately preceding each Interest Payment Date (each, a “Regular Record Date”). Holders must surrender Notes to a Paying Agent to
collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. At the Company’s option, interest may be paid by check
sent to the registered address of the Holder of this Note. 
 3.    Paying Agent and Registrar. Initially,
Deutsche Bank Trust Company Americas (the “Trustee”) will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co-Registrar without notice. 

4.    Indenture. The Company issued the Notes under an Indenture dated as of December 8, 1998 between the
Company and the Trustee as supplemented by the Ninth Supplemental Indenture dated as of April 3, 2003 and the Twenty-Second Supplemental Indenture dated as of March 15, 2018 between the Company and the Trustee (said Indenture, as so
supplemented, the “Indenture”). This Note is one of an issue of Securities of the Company issued under the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) as amended from time to time. The Notes are subject to all such terms, and Holders of the Notes are referred to the Indenture and such Act for a statement of them. Capitalized
terms used herein and not otherwise defined have the meanings set forth in the Indenture. The Notes are general unsecured and unsubordinated obligations of the Company ranking pari passu with all of the Company’s unsecured and unsubordinated
obligations. The Company may, subject to the terms of the Indenture and applicable law, issue Additional Notes  

  
 A-2-3 

 
under the Twenty-Second Supplemental Indenture. The Notes issued on March 15, 2018 and any Additional Notes subsequently issued shall be treated as a single class for all purposes of the
Twenty-Second Supplemental Indenture. The Indenture limits the ability of the Company to incur certain secured indebtedness and to enter into certain sale and leaseback transactions. 

5.    Optional Redemption.  

(a)    On or after March 15, 2020, the Company may redeem all or a part of the Notes, on any one or more occasions,

	 2022 and thereafter
	  	 	100.000	% 

 (b)    At any time prior to March 15, 2020, the Company may also redeem all or a part
of the Notes, on any one or more occasions, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but not including, the redemption
date, subject to the rights of holders of record of the Notes on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the redemption date. Calculation of the Applicable Premium is the
responsibility of the Company and the Trustee shall have no duty to calculate or verify the calculation of the Applicable Premium. 

(c)    At any time prior to March 15, 2020, the Company may, on any one or more occasions, use the net cash proceeds
from one or more Equity Offerings, to redeem in the aggregate for all such redemptions up to 35.0% of the aggregate principal amount of Notes issued (including the aggregate principal amount of any Additional Notes) at a redemption price equal to
104.500% of the aggregate principal amount of the Notes redeemed, plus accrued and unpaid interest thereon, if any, to, but not including, the applicable redemption date (subject to the right of Holders of record of the Notes on the relevant Regular
Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the redemption date), provided that: (A) at least 65.0% of the aggregate principal amount of Notes originally issued (including any
Additional Notes) remains outstanding immediately after the occurrence of such redemption and (B) each such redemption occurs within 90 days of the date of, and may be conditioned on, the closing of each such Equity Offering.

conditions precedent. 
 “Applicable Premium” means, with respect to any Note on any redemption date, the excess, if any,

payments due on such Note through March 15, 

  
 A-2-4 

 
2020 (excluding accrued but unpaid interest, if any, to, but not including, the redemption date) computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis
points, over (ii) the principal amount of such Note. 
 “Comparable Treasury Issue” means the United States Treasury

maturity under the caption “Treasury Constant Maturities,” or (b) if such release (or any successor release) is not published or does not contain such prices on such Business Day, the average of the Reference Treasury Dealer
Quotations for such redemption date. 
 “Disqualified Capital Stock” means that portion of any Capital Stock that, by its
terms (or by the terms of any security into which it is convertible or for which it is exchangeable at the option of the holder thereof), or upon the happening of any event (other than an event which would constitute a Change of Control), matures or
is mandatorily redeemable, pursuant to a sinking fund obligation or otherwise, or is redeemable at the sole option of the holder thereof (except, in each case, upon the occurrence of a Change of Control) on or prior to the date 91 days after the

 “Reference Treasury Dealer Quotations” means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount)

 A-2-5 

 “Treasury Rate” means, with respect to any redemption date, the rate per annum

 6.    Change of Control Offer. Upon the occurrence of a Change of Control Triggering Event,
the Company shall be required, as and to the extent set forth in the Indenture, to offer to purchase all of the outstanding Notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon

pay to it any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Notes or portion of a Note selected for redemption, or transfer or exchange any Notes for a period of 15 days before
selection of such Notes to be redeemed. 
 9.    Persons Deemed Owners. The registered holder of a Note may be
treated as the owner of it for all purposes. 
 10.    Unclaimed Money. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an
“abandoned property” law designates another Person. 
 11.    Amendment, Supplement, Waiver. The
Company and the Trustee may, without the consent of the holders of any outstanding Notes, amend, waive or supplement the Indenture or the Notes for certain specified purposes, including, among other things, curing ambiguities, defects or
inconsistencies, maintaining the qualification of the Indenture under the Trust Indenture Act of 1939 or making any other change that does not adversely affect the rights of any Holder in any material respect. Other amendments and modifications of
the Indenture or the Notes may be made by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of the outstanding Securities of all series affected, subject to certain exceptions
requiring the consent of the Holders of the particular Securities. 
 12.    Successor Corporation. When a
successor corporation assumes all the obligations of its predecessor under the Notes and the Indenture and the transaction complies with the terms of Article 5 of the Senior Indenture, the predecessor corporation, subject to certain exceptions, will
be released from those obligations. 

  
 A-2-6 

 13. Defaults and Remedies. Events of Default are set forth in the Indenture. Subject to
certain limitations in the Indenture, if an Event of Default (other than an Event of Default specified in Section 6.1(d) or (e) of the Senior Indenture with respect to the Company) occurs and is continuing, then the holders of not less
than 25% in aggregate principal amount of the outstanding Notes may, or the Trustee may, by written notice to the Company, and the Trustee at the request of not less than 25% in aggregate principal amount of the outstanding Notes will, declare the
principal of, plus accrued interest, if any, to be due and payable immediately. If an Event of Default specified in Section 6.1(d) or (e) of the Senior Indenture with respect to the Company occurs and is continuing, the Principal of and
accrued interest on all of the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee may require indemnity reasonably satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities of
all series issued under the Indenture that are affected may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing default (except a default in payment of principal or
interest) if it determines in good faith that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee. 

14. Trustee Dealing with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee. 

15. No Recourse Against Others. A director, officer, employee, stockholder or beneficiary, as such, of the Company shall not have any
liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issue of the Notes. 
 16. Defeasance. The Indenture contains
provisions (which provisions apply to this Note) for defeasance at any time of (a) the entire indebtedness of the Company in respect of this Note and (b) certain restrictive covenants and Defaults and Events of Default, in each case upon
compliance by the Company with certain conditions set forth therein. 
 17. Authentication. This Note shall not be valid until the
Trustee signs the certificate of authentication on the other side of this Note. 
 18. Abbreviations. Customary abbreviations may be
used in the name of a Holder of Notes or an assignee, such as: TEN COM (= tenants in common), TENANT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (=
