 ARTICLE 1 

APPLICATION OF SUPPLEMENTAL INDENTURE 

Section 1.01 Application of Fourth Supplemental Indenture. Notwithstanding any other provision of this Fourth Supplemental
Indenture, all provisions of this Fourth Supplemental Indenture are expressly and solely for the benefit of the Holders of the Notes and any such provisions shall not be deemed to apply to any other series of Securities issued under the Base
Indenture and shall not be deemed to amend, modify or supplement the Base Indenture for any purpose other than with respect to the Notes. Unless otherwise expressly specified, references in this Fourth Supplemental Indenture to specific Article
numbers or Section numbers refer to Articles and Sections contained in this Fourth Supplemental Indenture as they amend or supplement the Base Indenture, and not the Base Indenture or any other document. 

ARTICLE 2 
 DEFINITIONS

 Section 2.01 Certain Terms Defined in the Indenture. For purposes of this Fourth Supplemental Indenture, all capitalized
terms used but not defined herein shall have the meanings ascribed to such terms in the Base Indenture, as amended to date and further amended hereby. 

  
 2 








 Section 2.02 Definitions. 

(1) For the benefit of the Holders of each series of the Notes, Section 101 of the Base Indenture shall be amended by adding the following
new definitions: 
 “Bankruptcy Law” means Title 11, U.S. Code or any similar federal or state law for the relief of
debtors. 
 “Guarantee” means the guarantee of the Company’s obligations under the Notes of the applicable series and
the Indenture by the Guarantor under this Supplemental Indenture. When used as a verb “Guarantee” shall have a corresponding meaning. 

“Guaranteed Obligations” has the meaning specified in Section 3.01(a) hereof. 

“Guarantor” means the Person named as the “Guarantor” in the first paragraph of this Fourth Supplemental Indenture
until a successor Person shall have become such pursuant to the applicable provisions of the Indenture, and thereafter “Guarantor” shall mean such successor Person. 

(2) Section 101 of the Base Indenture shall be further amended as follows: 

“Opinion of Counsel” shall be amended by inserting the words “or the Guarantor” after “the Company”. 

ARTICLE 3 
 GUARANTEE

 Section 3.01 Unconditional Guarantee. With respect to each series of Notes, the Guarantor hereby unconditionally and
irrevocably guarantees, as a primary obligor and not merely as a surety, on a senior unsecured basis to each Holder of that series of Notes and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the
Indenture, that series of Notes or the obligations of the Company to such Holders or the Trustee hereunder or thereunder: (a) (x) the full and punctual payment of the principal of, premium, if any, and interest on the Notes of that series
when and as the same shall become due and payable, whether at maturity, upon redemption or repurchase, by acceleration or otherwise, (y) the due and punctual payment of interest on the overdue principal and (to the extent permitted by law)
interest, if any, on the Notes of that series (including interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding relating to the Company or the Guarantor, whether or
not a claim for post-filing or post-petition interest is allowed in such proceeding) and (z) the due and punctual payment and performance of all other obligations of the Company, in each case, to the Holders of that series of Notes or the
Trustee hereunder or thereunder (including amounts due the Trustee under Section 607 of the Base Indenture), all in accordance with the terms hereof and thereof (collectively, the “Guaranteed Obligations”); and
(b) in case of any extension of time of payment or renewal of any Notes of that series or any of such other obligations, the due and punctual payment and performance of Guaranteed Obligations in accordance with the terms of the extension or
renewal, whether at maturity, upon redemption or repurchase, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, or failing performance of 

  
 3 








 
any other obligation of the Company to the Holders of a particular series of Notes under the Indenture or under the Notes of that series, for whatever reason, the Guarantor shall be obligated to
pay, or to perform or cause the performance of, the same immediately. An Event of Default under the Indenture or the Notes shall constitute an event of default under the Guarantee with respect to that series of Notes, and shall entitle the Holders
of such series of Notes to accelerate the obligations of the Guarantor thereunder in the same manner and to the same extent as the obligations of the Company. The Guarantor further agrees that the Guaranteed Obligations may be extended or renewed,
in whole or in part, without notice or further assent from the Guarantor, and that the Guarantor shall remain bound under this Section 3.01 notwithstanding any extension or renewal of any Guaranteed Obligation. 

The Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability
of the Notes of that series or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to
enforce the same, whether or not a Guarantee is affixed to any particular Note, or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of the Guarantor. The Guarantor hereby waives the benefit of
diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants
that its Guarantee of a particular series of Notes shall not be discharged except by complete performance of the obligations contained in the Notes of that series, the Indenture and the Guarantee. The Guarantee of each series of Notes is a guarantee
of payment and not of collection. If any Holder of a particular series of Notes or the Trustee is required by any court or otherwise to return to the Company or to the Guarantor, or any custodian, trustee, liquidator or other similar official acting
in relation to the Company or the Guarantor, any amount paid by the Company or the Guarantor to the Trustee or such Holder, the Guarantee of that series of Notes, to the extent theretofore discharged, shall be reinstated in full force and effect.
The Guarantor further agrees that, as between it, on the one hand, and the Holders of each series of Notes and the Trustee, on the other hand, (a) subject to this Article Three the maturity of the obligations of a particular series of
Notes guaranteed hereby may be accelerated as provided in Article Five of the Base Indenture for the purposes of the Guarantee of that series of Notes, notwithstanding any stay, injunction or other prohibition preventing such acceleration in
respect of the obligations of that series of Notes guaranteed hereby, and (b) in the event of any acceleration of such obligations as provided in Article Five thereof, such obligations of a particular series of notes (whether or not due
and payable) shall forthwith become due and payable by the Guarantor for the purpose of the Guarantee of that series of Notes. 

Section 3.02 Limitation on Guarantor Liability. Each Holder and the Trustee, hereby confirms that it is the intention of all such
parties that the Guarantee of the Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the
extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantor hereby irrevocably agree that the obligations of the Guarantor shall be limited to the maximum amount as will, after giving effect
to such maximum amount and all other contingent and fixed liabilities of the Guarantor that are relevant under such laws and result in the obligations of the Guarantor under its Guarantee not constituting a fraudulent transfer or conveyance. 

  
 4 








 Section 3.03 Execution and Delivery of Guarantee. 

The Guarantor hereby agrees that its Guarantee of a particular series of Notes set forth in Section 3.01 shall remain in full
force and effect notwithstanding any failure to endorse on each Note of that series a notation of such Guarantee. 
 If an Officer of the
Guarantor whose signature is on this Fourth Supplemental Indenture no longer holds that office at the time the Trustee authenticates the Note on which such Guarantee is endorsed or at any time thereafter, the Guarantor’s Guarantee of such Note
shall nevertheless be valid. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due
delivery of any Guarantee set forth in this Fourth Supplemental Indenture on behalf of the Guarantor. 
 Section 3.04 Defeasance or
Discharge. 
 The Guarantee of the Guarantor shall be released if the Company (1) exercises its option under
Section 1302 or 1303 of the Base Indenture or (2) discharges its Obligations under the Indenture in accordance with Section 401 of the Base Indenture. 

The Trustee shall execute an appropriate instrument prepared by the Company evidencing the release of the Guarantor from its obligations under
its Guarantee upon receipt of a request by the Company or the Guarantor accompanied by an Officers’ Certificate and an Opinion of Counsel certifying as to the compliance with this Section 3.04; provided, however, that
the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers’ Certificates of the Company. 

Section 3.05 Waiver of Subrogation. 

Until the Indenture is discharged and all of the Notes of a particular series are discharged and paid in full, the Guarantor hereby
irrevocably waives and agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of the Company’s obligations under that series
of Notes or the Indenture and the Guarantor’s obligations under the Guarantee with respect to that series of Notes and the Indenture, in any such instance including any right of subrogation, reimbursement, exoneration, contribution,
indemnification, and any right to participate in any claim or remedy of the Holders of a particular series of Notes against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including
the right to take or receive from the Company, directly or indirectly, in cash or other assets or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to the Guarantor in
violation of the preceding sentence and any amounts owing to the Trustee or the Holders under the Notes, the Indenture, or any other document or instrument delivered under or in connection with such agreements or instruments, shall not have been
paid in full, such amount shall have been deemed to have been paid to the 

  
 5 








 
Guarantor for the benefit of, and held in trust for the benefit of, the Trustee or the Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited
and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or unmatured, in accordance with the terms of the Indenture. The Guarantor acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated by the Indenture and that the waiver set forth in this Section 3.05 is knowingly made in contemplation of such benefits. 

Section 3.06 Guaranteed Obligations Not Reduced. 

The obligations of the Guarantor with respect to a particular series of Notes shall not be satisfied, reduced or discharged solely by the
payment of such principal, premium, if any, interest, fees and other monies or amounts as may at any time prior to discharge of the Indenture pursuant to Article Four of the Base Indenture be or become owing or payable under or by virtue of
or otherwise in connection with the Notes of a particular series or the Indenture. 
 Section 3.07 Guaranteed Obligations
Reinstated. 
 The obligations of the Guarantor with respect to a particular series of Notes shall continue to be effective or shall be
reinstated, as the case may be, if at any time any payment which would otherwise have reduced the obligations of the Guarantor with respect to that series of Notes (whether such payment shall have been made by or on behalf of the Company or by or on
behalf of the Guarantor) is rescinded or reclaimed from any of the Holders of that series of Notes upon the insolvency, bankruptcy, liquidation or reorganization of the Company or the Guarantor or otherwise, all as though such payment had not been
made. If demand for, or acceleration of the time for, payment by the Company or the Guarantor is stayed upon the insolvency, bankruptcy, liquidation or reorganization of the Company or the Guarantor, all such Indebtedness otherwise subject to demand
for payment or acceleration shall nonetheless be payable by the Guarantor as provided herein. 
 Section 3.08 Waiver. 

Without in any way limiting the provisions of Section 3.01, the Guarantor hereby waives notice of acceptance hereof, notice of any
liability of the Guarantor hereunder, notice or proof of reliance by the Holders of a particular series of notes upon the obligations of the Guarantor, and diligence, presentment, demand for payment on the Company, protest, notice of dishonor or
non-payment of any of the Guaranteed Obligations, or other notice or formalities to the Company or the Guarantor of any kind whatsoever. 

Section 3.09 No Obligation To Take Action Against the Company. 

Neither the Trustee nor any other Person shall have any obligation to enforce or exhaust any rights or remedies against the Company or any
other Person or any property of the Company or any other Person before the Trustee is entitled to demand payment and performance by the Guarantor of its liabilities and obligations under its Guarantees of a particular series of Notes or under the
Indenture. 

  
 6 








 Section 3.10 Default and Enforcement. 

If the Guarantor fails to pay in accordance with Section 3.06 hereof, the Trustee may proceed in its name as trustee hereunder in
the enforcement of the Guarantee of a particular series of Notes of the Guarantor and the Guarantor’s obligations with respect to that series of Notes by any remedy provided by law, whether by legal proceedings or otherwise, and to recover from
the Guarantor the obligations. 
 Section 3.11 Amendment Etc. 

No amendment, modification or waiver of any provision of the Indenture relating to the Guarantor or consent to any departure by the Guarantor
or any other Person from any such provision shall in any event be effective unless it is signed by the Issuer, the Guarantor and the Trustee. 

Section 3.12 Acknowledgment. 

The Guarantor hereby acknowledges communication of the terms of the Indenture and the Notes and consents to and approves of the same. 

Section 3.13 Costs and Expenses. 

The Guarantor shall pay on demand by the Trustee any and all costs, fees and expenses (including legal fees and expenses on a solicitor and
client basis) incurred by the Trustee, its agents, advisors and counsel or any of the Holders in enforcing any of their rights under any Guarantee of a particular series of Notes. 

Section 3.14 No Merger or Waiver; Cumulative Remedies. 

No Guarantee shall operate by way of merger of any of the obligations of the Guarantor under any other agreement, including the Indenture. No
failure to exercise and no delay in exercising, on the part of the Trustee or the Holders of a particular series of Notes, any right, remedy, power or privilege hereunder or under the Indenture or the Notes, shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, remedy, power or privilege hereunder or under the Indenture or the Notes preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights,
remedies, powers and privileges in the Guarantee and under the Indenture, the Notes and any other document or instrument between the Guarantor or the Company and the Trustee are cumulative and not exclusive of any rights, remedies, powers and
privilege provided by law. 
 Section 3.15 Guarantee in Addition to Other Guaranteed Obligations. 

The obligations of the Guarantor under its Guarantee of each series of Notes and the Indenture are in addition to and not in substitution for
any other obligations to the Trustee or to any of the Holders of that series of Notes in relation to the Indenture or the Notes and any guarantees or security at any time held by or for the benefit of any of them. 

  
 7 








 Section 3.16 Successors and Assigns. 

The Guarantee shall be binding upon and inure to the benefit of the Guarantor and the Trustee and the other Holders and their respective
successors and permitted assigns, except that the Guarantor may assign any of its obligations hereunder or thereunder. 
 ARTICLE 4

 ADDITIONAL EVENT OF DEFAULT WITH RESPECT TO THE NOTES 

Section 4.01 Event of Default. Section 501 of the Base Indenture is hereby amended, in connection with this Fourth
Supplemental Indenture and with respect to the Notes, by inserting the following clause (10): 
 (10) The Guarantee ceases to be in full
force and effect (except as contemplated by the terms hereof) or the Guarantor denies or disaffirms its obligations under the Indenture or the Guarantee, other than by reason of the release of the Guarantee in accordance with the terms of the
Indenture, and such Default continues for 10 days. 
 ARTICLE 5 

APPLICATION OF MONEY COLLECTED 

Section 5.01 Application of Money Collected. Section 506 of the Base Indenture is hereby amended, in connection with this
Fourth Supplemental Indenture and with respect to the Notes, by deleting “THIRD: To the Company or to such party as a court of competent jurisdiction shall direct” in its entirety and replacing it with: 

“THIRD: To the Company or, if applicable, the Guarantor, as their respective interests may appear, or to such party as a
court of competent jurisdiction shall direct;” 
 ARTICLE 6 

MISCELLANEOUS 

Section 6.01 Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the
Trust Indenture Act which is required under such Act or deemed to be a part of and govern this Fourth Supplemental Indenture, such required or deemed provision shall control. If any provision of this Fourth Supplemental Indenture modifies or
excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Fourth Supplemental Indenture as so modified or to be excluded, as the case may be. 

Section 6.02 New York Law to Govern. This Fourth Supplemental Indenture and the Notes shall be governed by and construed in
accordance with the laws of the State of New York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute). The Trustee, the Company and the Guarantor agree to submit to the
non-exclusive jurisdiction of any United States federal or state court located in the borough of Manhattan, in the city of New York in any action or proceeding arising out of or relating to this Fourth Supplemental Indenture or the Notes. This
Fourth Supplemental Indenture is subject to the provisions of the Trust Indenture Act that are required to be part of the Indenture and shall, to the extent applicable, be governed by such provisions. 

  
 8 








 The Trustee, the Company and the Guarantor hereby knowingly, voluntarily and intentionally waive
any rights they may have to a trial by jury in respect of any litigation based hereon, or arising out of, under or in connection with this Fourth Supplemental Indenture or any course of conduct, course of dealing, statements (whether oral or
written) or actions of the Trustee, the Company or the Guarantor relating thereto. The Company and the Guarantor acknowledge and agree that they have received full and sufficient consideration for this provision and that this provision is a material
inducement for the Trustee entering into this Fourth Supplemental Indenture. 
 Section 6.03 Counterparts. This Fourth
Supplemental Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. The exchange of copies of this
Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the
parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. 
 Section 6.04
Separability Clause. In case any provision in this Fourth Supplemental Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

Supplemental Indenture, is in all respects ratified and confirmed. The Indenture shall be read, taken and construed as one and the same instrument. All provisions included in this Fourth Supplemental Indenture supersede any conflicting provisions

Section 6.06 Effectiveness. The provisions of this Fourth Supplemental Indenture shall become effective as of the date hereof.

Indenture, but on the terms and conditions set forth in the Indenture, including the terms and provisions defining and limiting the liabilities and responsibilities of the Trustee. Without limiting the generality of the foregoing, the Trustee shall
not be responsible in any manner whatsoever for or with respect to any of the recitals or statements contained herein, all of which recitals or statements are made solely by the Company, or for or with respect to (i) the validity or sufficiency
of this Supplemental Indenture or any of the terms or provisions hereof, (ii) the proper authorization hereof by the Company by action or otherwise, (iii) the due execution hereof by the Company or (iv) the consequences of any
amendment herein provided for, and the Trustee makes no representation with respect to any such matters.
