 REVERSE OF NOTE 
 This Security is one of the duly authorized issue of unsecured debentures, notes or other evidences of indebtedness of the Company (hereinafter called the “Securities”), of the series hereinafter specified,
all issued or to be issued under and pursuant to the indenture dated as of [            ], 2006 (hereinafter called the “Indenture”), duly executed and delivered by the Company
and Law Debenture Trust Company of New York, as Trustee (herein called the “Trustee”, which term includes any successor Trustee under the Indenture), to which Indenture and any other indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, obligations, duties, and immunities thereunder of the Trustee and any agent of the Trustee, any paying agent, the Company and the Holders of the Securities and of the terms upon which
the Securities are issued and are to be authenticated and delivered. This Security is one of the series designated on the face hereof. By the terms of the Indenture, additional Securities of this series and of other separate series, which may vary
as to date, amount, seniority, stated maturity (if any), interest rate or method of calculating the interest rate and in other respects as therein provided, may be issued in an unlimited amount. 
 Payments of principal and interest on the Securities will be made without withholding or deduction for or on account of any present or future taxes,
duties, assessments or other governmental charges imposed or levied by or on behalf of Japan of any political subdivision thereof having power to tax, unless otherwise required by law. If any such withholding or deduction is required by Japanese
law, a Holder of Securities will be paid, as long as such Holder is not a Japanese corporation or a resident of Japan for Japanese tax purposes, such additional amounts as may be necessary in order that every net payment made by the Company on the
Securities after deduction or withholding for or on account of any such present or future tax, duty, assessment or other governmental charge will not be less than the amount that, in the absence of such deduction or withholding, would have been due
and payable on such Securities. However, additional amounts will not be required to be paid under any of the following circumstances: 
  

	 	•	 	the Holder or beneficial owner of the Security is subject to such tax, duty, assessment or other governmental charge by reason of having some connection to Japan, other than the
mere holding of the Security; 

  

	 	•	 	the tax, duty, assessment or other governmental charge is imposed or withheld because the Holder or beneficial owner failed to make a declaration or satisfy any information
requirements that the statutes, treaties, regulations or administrative practices of Japan require as a precondition to exemption from all or part of such tax or governmental charge; 

  

	 	•	 	the Security is presented for payment more than 30 days after the Security became due or after the full payment was provided for, whichever occurs later, except to the extent that
the Holder thereof would have been entitled to additional amounts on presenting the same for payment on the last day of such period of 30 days; 

  

	 	•	 	the withholding or deduction is imposed pursuant to the European Union Directive 2003/48/EC regarding the taxation of savings income, or any law implementing such directive;

  

	 	•	 	the withholding or deduction is imposed on a Holder or beneficial owner who could have avoided such withholding or deduction by presenting its Security to another paying agent;

  

 -1- 

	 	•	 	the Holder is a fiduciary or partnership or is not the sole beneficial owner of the payment of the principal of, or any interest on, any Security, and the laws of the taxing
jurisdiction require the payment to be included for tax purposes in the income of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner, in each case, who would not have been entitled to such
additional amounts had it been the Holder of such Security; or 

  

	 	•	 	any combination of the above. 

 The Company will
(i) make any required withholding or deduction and (ii) remit the full amount deducted or withheld to the Japanese taxing authority in accordance with applicable law. The Company will use all reasonable efforts to obtain certified copies
of tax receipts evidencing the payment of any tax, duty, assessment or other governmental charge so deducted or withheld from the Japanese taxing authority imposing such tax, duty, assessment or other governmental charge and will provide such
certified copies to each holder. The Company will attach to each certified copy a certificate stating (x) that the amount of withholding tax, duty, assessment or other governmental charge evidenced by the certified copy was paid in connection
with payments in respect of the principal amount of Securities then outstanding and (y) the amount of such withholding tax, duty, assessment or other governmental charge paid per $1,000 principal amount of the Securities. Copies of such
documentation will be available for inspection during ordinary business hours at the office of the Trustee by the Holders of the Securities upon request and will be made available at the office of the paying agent. 
 The obligation to pay additional amounts with respect to any taxes, duties, assessments and other governmental charges shall not apply to (A) any
estate, inheritance, gift, sales, transfer, personal property or any similar tax, duty, assessment, fee or other governmental charge or (B) any tax, duty, assessment, fee or other governmental charge which is payable otherwise than by deduction
or withholding from payments of principal or interest on this Security; provided that, except as otherwise set forth herein and in the Indenture, the Company shall pay all stamp, court or documentary taxes or any excise or property taxes, charges or
similar levies and other duties, if any, which may be imposed by Japan, the United States or any respective political subdivision or any taxing authority thereof or therein, with respect to the Indenture or as a consequence of the issuance,
execution, delivery or registration of this Security. 
 References to principal or interest in respect of the Securities shall be deemed to
include any additional amounts due which may be payable as set forth here and in the Indenture. 
 The Company has the option to redeem the
Securities prior to maturity if, upon any change in Japanese law occurring on or after the issue date, the Company would be required to pay additional amounts as described above, in which case the Company may redeem the Securities in whole, but not
in part, at a redemption price equal to 100% of the principal amount of the Securities plus accrued interest to the redemption date. Furthermore, the Company must give the Holders between 30 and 60 days notice before redeeming the Securities.

 So long as any of the Securities remain outstanding the Company may not create or permit to subsist any pledge, lien or other charge upon
the whole or any part of its undertaking, assets or revenues present or future to secure, for the benefit of the holders thereof, any External Indebtedness, as defined below, without according or procuring to be accorded to the debt obligations of
the Company under the Securities and the Indenture the same security as is granted to such External Indebtedness or such other security or guarantee as shall be approved by more than 50% of the outstanding principal amount of the Securities.
External Indebtedness means any of indebtedness of the Company or any of its consolidated subsidiaries, with a stated maturity of more than one year from the creation thereof, which is represented by bonds, debentures, notes or any other similar
debt securities which are quoted, listed or ordinarily dealt in, or are intended to be quoted, listed or ordinarily dealt in, on a stock exchange or on any over-the-counter or any other similar securities market outside Japan and which are by their
terms repayable or confer a right to receive repayment in any currency other than yen or are denominated in yen, if a majority of the aggregate nominal amount thereof is initially distributed outside Japan by or with the Company’s authorization
(or guarantees, indemnities or other like obligations (in each case granted or undertaken for the benefit of the holders of such securities to secure the payment of such indebtedness) in respect of such indebtedness). 
  

 -2- 

 The Company reserves the right, from time to time, without the consent of the Holders of the Securities,
to issue additional Securities on terms and conditions identical to those of the Securities, which additional Securities shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the Securities. The
Company may also issue other securities under the Indenture as part of a separate series that have different terms from the Securities. 
 The Company may change the paying agent or registrar without prior notice to the Holders of the Securities, and the Company or any of its subsidiaries may act as paying agent or registrar. 
 A Holder of Securities issued in definitive form may transfer or exchange Securities in accordance with the Indenture. As described in the legend on the
face of this global note, interest payments on such Securities issued in definitive form will be subject to Japanese income taxation unless the Holder establishes the matters set forth therein. Such legend concerning Japanese taxation shall also be
included on the face of any Securities issued in definitive form. The registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and to pay any taxes and fees required by law or
permitted by the Indenture. The Company will treat the registered Holder of a Security as the owner of that Security for all purposes, except as described above. 
 If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided
in the Indenture. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the
rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of at least not less than a majority
in aggregate principal amount of the Securities at the time Outstanding of all series to be affected (voting as a class). The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 
 No reference herein to the
Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the
coin or currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of
this Security is registrable, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the security registrar duly executed by, the Holder hereof or his attorney duly authorized in writing and thereupon one or more new Securities of this series and of like tenor,
of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
  

 -3- 

 The Securities of this series are issuable only in registered form without coupons in denominations of
$1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like
tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any
such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. 
 Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Security shall be governed by and construed in accordance with the laws of the State of New York, except with respect to its authorization and
execution by the Company and other matters required to be governed by the laws of Japan. 
 All terms used in this Security which are defined
in the Indenture shall have the meanings assigned to them in the Indenture.

Trustee may require a Paying Agent to pay all funds held by it relating to the Notes to the Trustee. The Issuer at any time may require a Paying Agent to pay all funds held by it relating to the Notes to the Trustee. Upon payment over to the
Trustee, the Paying Agent (if other than the Issuer) shall have no further liability for such funds. If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all funds
held by it as Paying Agent. Upon any Event of Default under Sections 4.1(d) and (e) hereof relating to the Issuer, the Trustee shall serve as Paying Agent for the Notes.

at such other times as the Trustee may request in writing, a list in such form and as of such date or such shorter time as the Trustee may allow, as the Trustee may reasonably require of the names and addresses of the Holders and the Issuer shall

 (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. The Issuer shall exchange Global Notes for
Definitive Notes if: (1) the Issuer delivers to the Trustee a notice from the Depositary that the Depositary is unwilling or unable to continue to act as Depositary for the Global Notes or that it has ceased to be a clearing agency registered
under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuer within 120 days after the date of such notice from the Depositary; (2) the Issuer at its option determines that the Global Notes shall be
exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; or (3) a Default or Event of Default shall have occurred and be continuing. Upon the occurrence of any of the preceding events in clauses (1),
(2) or (3) above, Definitive Notes shall be issued in denominations of $1,000 or integral multiples thereof and in such names as the Depositary shall instruct the Trustee in writing. Global Notes also may be exchanged or replaced, in whole
or in part, as provided in Sections 2.7 and 2.10 hereof. Except as provided above, every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.6 or Section 2.7 or
2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.6(a), and beneficial interests in a Global Note may not
be transferred and exchanged other than as provided in Section 2.6(b), (c), (d), (e) or (h) hereof.

instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.6(b). 
 (c)
Transfer and Exchange of Beneficial Interests for Definitive Notes. Subject to Section 2.6(a) hereof, if any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to
transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Note, then, the Trustee shall 
  

 12 

 reduce or cause to be reduced in a corresponding amount pursuant to Section 2.6(g) hereof the aggregate principal
amount of the applicable Global Note, and the Issuer shall execute and, upon receipt of an Authentication Order in accordance with Section 2.2 hereof, the Trustee shall authenticate and deliver a Definitive Note in the appropriate principal
amount to the Person designated by the holder of such beneficial interest in instructions delivered to the Registrar by the Depositary and the applicable Participant or Indirect Participant on behalf of such holder. Any Definitive Note issued in
exchange for a beneficial interest pursuant to this Section 2.6(c) shall be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest shall designate in such instructions.
The Trustee shall deliver such Definitive Notes to the Persons in whose names such Notes are registered. 
 (d) Transfer and Exchange of
Definitive Notes for Beneficial Interests. A holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Note to a Person who takes delivery thereof in the form of a beneficial
interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer in form satisfactory to the Registrar, the Trustee shall cancel the applicable Definitive Note and increase or cause to be increased in a corresponding
amount pursuant to Section 2.6(g) hereof the aggregate principal amount of one of the Global Notes. 
 (e) Transfer and Exchange of
Definitive Notes for Definitive Notes. Upon request by a holder of Definitive Notes and such holder’s compliance with the provisions of this Section 2.6(e), the Registrar shall register the transfer or exchange of Definitive Notes.

Note shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who shall
take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global
Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest

Order in accordance with Section 2.2 hereof, shall authenticate a replacement Note. If required by the Trustee or the Issuer, the Holder of such Note shall provide indemnity sufficient, in the judgment of the Trustee or the Issuer, as
applicable, to protect the Issuer, the Trustee, any Agent and any Authenticating Agent from any loss that any of them may suffer in connection with such replacement. If required by the Issuer, such Holder shall reimburse the Issuer for its
reasonable expenses in connection with such replacement.

 In determining whether the Holders of
the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or by any Affiliate of the Issuer shall be considered as though not Outstanding, except that for the purposes of determining whether
the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned shall be so disregarded.

 Until certificates representing Notes are ready for
delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order in accordance with Section 2.2 hereof, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may

notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer shall fix or cause to be fixed each such special record date and payment date, provided that no such
special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the
expense of the Issuer) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
 Section 2.13 CUSIP or ISIN Numbers. 
 The Issuer in issuing the Notes
may use “CUSIP” and/or “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” and/or “ISIN” numbers in notices of redemption as a convenience to Holders; provided, however, that
any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or notice of an offer to purchase and that reliance may be placed only on the
other identification numbers printed on the Notes, and any such redemption or offer to purchase shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly notify the Trustee of any change in the “CUSIP”
and/or “ISIN” numbers.

 (1) the
aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; and 
 (2)

(except for leases of three years or less), whereby such property has been or is to be sold or transferred by the Issuer or any Subsidiary to such Person (herein referred to as a “Sale and Lease-Back Transaction”), unless: 
 (i) the Issuer or any Subsidiary would, at the time of entering into a Sale and Lease-Back Transaction, be entitled to incur Indebtedness

more than 15 days prior to the time such information is furnished. Holders may communicate pursuant to §312(b) of the Trust Indenture Act of 1939 with other Holders with respect to their rights under this Indenture or the Notes. The Issuer, the

 The Issuer covenants to file with the Trustee, within 15 days after the Issuer is required
to file the same with the Commission, copies of the annual reports and of the information, documents, and other reports which the Issuer may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Securities
Exchange Act of 1934. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
 Section 3.9 Reports by the Trustee.

preceding the reporting date, no report need be transmitted. The Trustee shall also comply with §313(b) of the Trust Indenture Act.

or whose breach is elsewhere in this Section specifically dealt with) and continuance of such default or breach for a period of 60 days (or 180 days in the case of a Reporting Failure) after there has been given, by registered or certified mail, to
the Issuer and the Guarantor by the Trustee or to the Issuer, the Guarantor and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Notes, a written notice specifying such default or breach and requiring it to
be remedied and stating that such notice is a “Notice of Default” hereunder; or 
 (d) either (1) default in payment of any
Indebtedness of the Issuer, the Guarantor or any Subsidiary of the Issuer within any applicable grace period after final maturity or (2) the acceleration of Indebtedness of the Issuer, the Guarantor or any Subsidiary of the Issuer by the

Guarantor or any Significant Subsidiary or for any substantial part of its property, or the making by the Issuer, the Guarantor or any Significant Subsidiary of any general assignment for the benefit of creditors; 
  

 24 

 provided, however, that the occurrence of any of the events described in the foregoing clause (c) shall not
constitute an Event of Default if such occurrence is the result of changes in generally accepted accounting principles as recognized by the American Institute of Certified Public Accountants at the date as of which this Indenture is executed and a
certificate to such effect is delivered to the Trustee by the Issuer’s independent public accountants. 
 If an Event of Default
described in clauses (a), (b), (c) or (d) above occurs and is continuing, then, and in each and every such case, unless the principal of all the Notes shall have already become due and payable, either the Trustee or the Holders of not less
than 25% in aggregate principal amount of all the Notes then Outstanding hereunder, by notice in writing to the Issuer and the Guarantor (and to the Trustee if given by Noteholders), may declare the entire principal of all of the Notes then
Outstanding, and interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable. If an Event of Default described in clause (e) or (f) occurs and is
continuing, then and in each and every such case, unless the principal of all the Notes shall have already become due and payable, the entire principal of all of the Notes then Outstanding, and interest accrued thereon, if any, will become
immediately due and payable without any declaration of acceleration or other act on the part of the Trustee or any Holders. 
 The foregoing
provisions, however, are subject to the condition that if, at any time after the principal of the Notes shall have been so declared due and payable or become automatically due and payable, and before any judgment or decree for the payment of the
moneys due shall have been obtained or entered as hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all the Notes and the principal of any and all Notes
which shall have become due otherwise than by acceleration (with interest upon such principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest, at the same rate as the rate of
interest specified in the Notes and such amount as shall be sufficient to cover reasonable compensation to the Trustee and each predecessor Trustee and their agents, attorneys and counsel, and all other expenses and liabilities incurred, and all
advances made, by the Trustee and each predecessor Trustee except as a result of negligence or bad faith, and if any and all Events of Default under this Indenture, other than the non-payment of the principal of Notes which shall have become due by
acceleration, shall have been cured, waived or otherwise remedied as provided herein then and in every such case the Holders of a majority in aggregate principal amount of all the Notes then Outstanding, by written notice to the Issuer, the
Guarantor and to the Trustee, may waive all defaults with respect to the Notes and rescind and annul such declaration and its consequences, but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or
shall impair any right consequent thereon. 
 Section 4.2 Collection of Indebtedness by Trustee; Trustee May Prove
Debt. 
 The Issuer covenants that (a) in case default shall be made in the payment of any installment of interest on any of the
Notes when such interest shall have become due and payable, and such default shall have continued for a period of 30 days or (b) in case default shall 
  

 25 

 be made in the payment of all or any part of the principal of any of the Notes when the same shall have become due and
payable, whether upon maturity of the Notes or upon any redemption or by declaration or otherwise, then upon demand of the Trustee, the Issuer will pay to the Trustee for the benefit of the Holders of the Notes the whole amount that then shall have
become due and payable on all Notes for principal or interest, as the case may be (with interest to the date of such payment upon the overdue principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue
installments of interest at the same rate as the rate of interest specified in the Notes); and in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the
Trustee and each predecessor Trustee, their respective agents, attorneys and counsel, and any expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee except as a result of its negligence or bad faith.

 Until such demand is made by the Trustee, the Issuer may pay the principal of and interest on the Notes to the registered Holders, whether
or not the principal of and interest on Notes be overdue. 
 In case the Issuer shall fail forthwith to pay such amounts upon such demand,
the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or
proceedings to judgment or final decree, and may enforce any such judgment or final decree against the Issuer or other obligor upon the Notes and collect in the manner provided by law out of the property of the Issuer or other obligor upon the
Notes, wherever situated, the moneys adjudged or decreed to be payable. 
 In case there shall be pending proceedings relative to the Issuer,
the Guarantor or any other obligor upon the Notes under Title 11 of the United States Code or any other applicable federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Issuer, the Guarantor or their property or such other obligor, or in case of any other comparable judicial proceedings relative to
the Issuer, the Guarantor or other obligor upon the Notes, or to the creditors or property of the Issuer, the Guarantor or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such proceedings or otherwise: 
 (a) to file and prove a claim or claims for the whole amount of principal and interest owing and unpaid in respect of the Notes, and to
file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation to the Trustee and each predecessor Trustee, and their respective agents, attorneys and
counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of negligence or bad faith) and of the Holders allowed in any judicial proceedings
relative to the Issuer or other obligor upon the Notes, or to the creditors or property of the Issuer or such other obligor, 
  

 26 

 (b) unless prohibited by applicable law and regulations, to vote on behalf of the Holders
of the Notes in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or Person performing similar functions in comparable proceedings, and 
 (c) to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received
with respect to the claims of the Holders and of the Trustee on their behalf, and any trustee, receiver, or liquidator, custodian or other similar official is hereby authorized by each of the Holders to make payments to the Trustee, and, in the
event that the Trustee shall consent to the making of payments directly to the Holders, to pay to the Trustee such amounts as shall be sufficient to cover reasonable compensation to the Trustee, each predecessor Trustee and their respective agents,
attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee except as a result of negligence or bad faith. 
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Holder any
plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding except, as aforesaid, to vote
for the election of a trustee in bankruptcy or similar Person. 
 All rights of action and of asserting claims under this Indenture, or under
any of the Notes, may be enforced by the Trustee without the possession of any of the Notes or the production thereof in any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought
in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Holders of the Notes in respect of which such action was taken. 
 In any proceedings brought by the Trustee (and also
any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes in respect to which such action was taken, and it shall not be
necessary to make any Holders of the Notes parties to any such proceedings. 
 Section 4.3 Application of
Proceeds. 
 Any moneys collected by the Trustee pursuant to this Article Four shall be applied in the following order at the date or
dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal or interest, upon presentation of the several Notes in respect of which monies have been collected and stamping (or otherwise noting) thereon the
payment, or issuing Notes in reduced principal amounts in exchange for the presented Notes, if only partially paid, or upon surrender thereof if fully paid: 
  

 27 

 FIRST: To the payment of costs and expenses applicable to the Notes in respect of which
monies have been collected, including reasonable compensation to the Trustee and each predecessor Trustee and their respective agents and attorneys and of all expenses and liabilities incurred, and all advances made, by the Trustee and each
predecessor Trustee except as a result of negligence or bad faith; 
 SECOND: In case the principal of the Notes in respect of
which moneys have been collected shall not have become and be then due and payable, to the payment of interest on the Notes in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest
has been collected by the Trustee) upon the overdue installments of interest at the same rate as the rate of interest specified in such Notes, such payments to be made ratably to the Persons entitled thereto, without discrimination or preference;

 THIRD: In case the principal of the Notes in respect of which moneys have been collected shall have become and shall be
then due and payable, to the payment of the whole amount then owing and unpaid upon all the Notes for principal and interest, with interest upon the overdue principal, and (to the extent that such interest has been collected by the Trustee) upon
overdue installments of interest at the same rate as the rate of interest specified in the Notes; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Notes, then to the payment of such principal
and interest, without preference or priority of principal over interest, or of interest over principal, or of any installment of interest over any other installment of interest, ratably to the aggregate of such principal and accrued and unpaid
interest; and 
 FOURTH: To the payment of the remainder, if any, to the Issuer. 
 Section 4.4 Suits for Enforcement. 
 In case an Event of Default has occurred, has not been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture
or in aid of the exercise of any power granted in this Indenture or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 
 Section 4.5 Restoration of Rights on Abandonment of Proceedings. 
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee, then and in every such
case the Issuer, the Guarantor and the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Issuer, the Guarantor, the Trustee and the Holders shall continue as though no
such proceedings had been taken. 
  

 28 

 Section 4.6 Limitations on Suits by Holders. 
 No Holder of any Note shall have any right by virtue or by availing of any provision of this Indenture to institute any action or proceeding at law or in
equity or in bankruptcy or otherwise upon or under or with respect to this Indenture, or for the appointment of a trustee, receiver, liquidator, custodian or other similar official or for any other remedy hereunder, unless such Holder previously
shall have given to the Trustee written notice of default and of the continuance thereof, as herein before provided, and unless also the Holders of not less than 25% in aggregate principal amount of the Notes shall have made written request upon the
Trustee to institute such action or proceedings in its own name as Trustee hereunder and shall have offered to the Trustee such indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred therein or thereby and
the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee
pursuant to Section 4.9; it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee, that no one or more Holders of Notes shall have any right in any
manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other such Holder of Notes, or to obtain or seek to obtain priority over or preference to any other such Holder or to
enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Notes. For the protection and enforcement of the provisions of this Section, each and every Holder and the
Trustee shall be entitled to such relief as can be given either at law or in equity. 
 Section 4.7 Unconditional
Right of Holders to Institute Certain Suits. 
 Notwithstanding any other provision in this Indenture and any provision of any Note,
the right of any Holder of any Note to receive payment of the principal of and interest on such Note on or after the respective due dates expressed or provided for in such Note, or to institute suit for the enforcement of any such payment on or
after such respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 4.8
Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default. 
 Except as provided in Section 4.6, no right
or remedy herein conferred upon or reserved to the Trustee or to the Holders of Notes is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every
other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy. 
 No delay or omission of the Trustee or of any Holder of Notes to exercise any right or power accruing upon
any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an acquiescence therein; and, subject to Section 4.6, every power and remedy
given by this Indenture or by law to the Trustee or to the Holders of Notes may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders of Notes. 
  

 29 

 Section 4.9 Control by Holders of Notes. 
 The Holders of a majority in aggregate principal amount of the Notes at the time Outstanding shall have the right to direct the time, method, and place of
conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to the Notes by this Indenture; provided that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture and provided further that (subject to the provisions of Section 5.1) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that
the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith by its board of directors, the executive committee, or a trust committee of directors or Responsible Officers of the Trustee shall determine that the
action or proceedings so directed would involve the Trustee in personal liability or if the Trustee in good faith shall so determine that the actions or forebearances specified in or pursuant to such direction would be unduly prejudicial to the
interests of Holders of the Notes not joining in the giving of said direction, it being understood that (subject to Section 5.1) the Trustee shall have no duty to ascertain whether or not such actions or forebearances are unduly prejudicial to
such Holders. 
 Nothing in this Indenture shall impair the right of the Trustee in its discretion to take any action deemed proper by the
Trustee and which is not inconsistent with such direction or directions by Holders. 
 Section 4.10 Waiver of Past
Defaults. 
 Prior to the acceleration of the maturity of any Notes as provided in Section 4. 1, the Holders of a majority in
aggregate principal amount of the Notes at the time Outstanding with respect to which an Event of Default shall have occurred and be continuing may on behalf of the Holders of all such Notes waive any past default or Event of Default described in
Section 4.1 and its consequences, except a default in respect of a covenant or provision hereof which cannot be modified or amended without the consent of the Holder of each Note affected. In the case of any such waiver, the Issuer, the
Guarantor, the Trustee and the Holders of all such Notes shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

 Upon any such waiver, such default shall cease to exist and be deemed to have been cured and not to have occurred, and any Event of
Default arising therefrom shall be deemed to have been cured, and not to have occurred for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent
thereon. 
  

 30

Defaults known to the Trustee (i) if any Notes are then Outstanding, to the Holders thereof, by publication at least once in an Authorized Newspaper in the Borough of Manhattan, The City of New York and at least once in an Authorized Newspaper
in London (and, if required by Section 3.8, at least once in an Authorized Newspaper in Luxembourg) and (ii) to all Holders of Notes in the manner and to the extent provided in §313(c) of the Trust Indenture Act of 1939, unless in
each case such Defaults shall have been cured before the mailing or publication of such notice; provided that, except in the case of default in the payment of the principal of or interest on any of the Notes, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors or trustees and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in
the interests of the Holders. 
 Section 4.12 Right of Court to Require Filing of Undertaking to Pay Costs.

 All parties to this Indenture agree, and each Holder of any Note by his acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of
the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder or group of Holders holding in the aggregate more than 10% in
aggregate principal amount of the Notes or, in the case of any suit relating to or arising under clause (c) or (f) of Section 4.1 or to any suit instituted by any Holder for the enforcement of the payment of the principal of or
interest on any Note on or after the due date expressed in such Note or any date fixed for redemption. 
 ARTICLE FIVE 
 CONCERNING THE TRUSTEE 
 Section 5.1 Duties and Responsibilities of the Trustee; During Default; Prior to Default. 
 With respect to the Holders of Notes issued hereunder, the Trustee, prior to the occurrence of an Event of Default with respect to the Notes and after the curing or waiving of all Events of Default which may have occurred, undertakes to
perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default with respect to the Notes has occurred (which has not been cured or waived) the Trustee shall exercise with respect to the Notes
such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

  

 31 

 No provision of this Indenture shall be construed to relieve the Trustee from liability for its own
negligent action, its own negligent failure to act or its own willful misconduct, except that 
 (a) prior to the occurrence of an Event of
Default with respect to the Notes and after the curing or waiving of all such Events of Default with respect to which may have occurred: 
 (i) the duties and obligations of the Trustee with respect to the Notes shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such
duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such statements, certificates or opinions which by any
provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the
accuracy or mathematical calculations or other facts stated therein); 
 (b) the Trustee shall not be liable for any error of judgment made
in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the
Holders pursuant to Section 4.9 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture. 
 None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there shall be reasonable ground for believing that the repayment of such funds or adequate indemnity against such liability is not reasonably
assured to it. 
 The provisions of this Section 5.1 are in furtherance of and subject to Sections 315 and 316 of the Trust Indenture
Act of 1939. 
  

 32 

 Section 5.2 Certain Rights of Trustee. 
 In furtherance of and subject to the Trust Indenture Act of 1939, and subject to Section 5.1:

party or parties;

assistant secretary of Boardwalk GP; 
 (c) the Trustee may consult with counsel of its selection and any advice or any
Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in reliance thereon in accordance with such advice or Opinion of Counsel;

 (d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture at the
request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities
which might be incurred therein or thereby, 
 (e) the Trustee shall not be liable for any action taken or omitted by it in
good faith and believed by it to be authorized or within the discretion, rights or powers conferred upon it by this Indenture; 
 (f) prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all Events of Default, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order, approval, appraisal, bond, debenture, note, Note, or other paper or document unless requested in writing so to do by the Holders of not less than a majority in aggregate
principal amount of the Notes then Outstanding; provided that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a condition to proceeding; the reasonable expenses of
every such investigation shall be paid by the Issuer or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the Issuer upon demand; 
 (g) the Trustee may execute any of the trusts or powers or perform any duties either directly or by or through agents or attorneys not regularly in its employ and the Trustee shall not be responsible for any
misconduct or negligence on the part of any such agent or attorney appointed by it with due care; 
  

 33 

 (h) in no event shall the Trustee be responsible or liable for special, indirect, or
consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; 
 (i) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture; 
 (j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; and

officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in
any such certificate previously delivered and not superseded.

Disposition of Notes or Applications of Proceeds Thereof. 
 The recitals contained herein and in the Notes, except the Trustee’s
certificates of authentication, shall be taken as the statements of the Issuer, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representation as to the validity or sufficiency of this Indenture or of
the Notes, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform all its obligations hereunder, and that the statements made by it in the Statement of Eligibility on
Form T-1 supplied to the Issuer are true and accurate. The Trustee shall not be accountable for the use or application by the Issuer of any of the Notes or of the proceeds thereof. 
 Section 5.4 Trustee and Agents May Hold Notes; Collections etc. 
 The Trustee or any agent of the Issuer or the Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee or such agent and may otherwise deal with
the Issuer and receive, collect, hold and retain collections from the Issuer with the same rights it would have if it were not the Trustee or such agent, subject to the provisions of the Trust Indenture Act of 1939 relating to conflicts of interest
and preferential claims. 
 Section 5.5 Moneys Held by Trustee. 
 Subject to the provisions of Section 9.4 hereof, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust
for the purposes for which they were received, but need not be segregated from other funds except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of the Issuer or the Trustee shall be under any liability for
interest on any moneys received by it hereunder.

 Section 5.6 Compensation and Indemnification of Trustee and Its Prior
Claim. 
 Each of the Issuer and the Guarantor covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, such compensation as shall be agreed upon in writing (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and each of the Issuer and the Guarantor covenants and agrees to
pay or reimburse the Trustee and each predecessor Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ) except any such expense, disbursement or advance as shall be determined to have been caused by its own
negligence or willful misconduct. Each of the Issuer and the Guarantor also covenants to indemnify the Trustee and each predecessor Trustee for, and to hold it harmless against, any and all loss, liability claim, damage or expense, including taxes
(other than those based on or measured by the income of the Trustee) incurred without negligence or willful misconduct faith on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder
and its duties hereunder, including the costs and expenses of defending itself against or investigating any claim of liability (whether asserted by the Issuer, any Holder or any other Person) in the premises. The obligations of the Issuer and the
Guarantor under this Section to compensate and indemnify the Trustee and each predecessor Trustee and to pay or reimburse the Trustee and each predecessor Trustee for expenses, disbursements and advances shall constitute additional indebtedness
hereunder and shall survive the satisfaction and discharge of this Indenture or the resignation or removal of the Trustee. Such additional indebtedness shall be a senior claim to that of the Notes upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the benefit of the Holders of particular Notes, and the Notes are hereby subordinated to such senior claim. When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 4.1(d) or 4.1(e), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or state
bankruptcy, insolvency or other similar law. 
 Section 5.7 Right of Trustee to Rely on Officers’
Certificate. 
 Subject to Sections 5.1 and 5.2, whenever in the administration of the trusts of this Indenture the Trustee shall deem
it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of
negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof. 
  

 35 

 Section 5.8 Persons Eligible for Appointment as Trustee. 
 The Trustee shall at all times be a corporation organized and doing business under the laws of the United States of America or of any state or the
District of Columbia having a combined capital and surplus of at least $50,000,000, and which is eligible in accordance with the provisions of § 310(a) of the Trust Indenture Act of 1939. If such corporation publishes reports of condition at
least annually, pursuant to law or to the requirements of a federal, state or District of Columbia supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be
its combined capital and surplus as set forth in its most recent report of condition so published. No obligor on the Notes or Person directly or indirectly controlling, controlled by, or under common control with such obligor shall serve as Trustee.
The Trustee shall comply with § 310(b) of the Trust Indenture Act of 1939; provided that, there shall be excluded from the operation of § 310(b)(1) of the Trust Indenture Act of 1939, this Indenture or indentures under which other
securities or certificates of interest, or participation in other securities of the Issuer are outstanding if the requirements for such exclusion set forth in § 310(b)(1) of the Trust Indenture Act of 1939 are met. 
 Section 5.9 Resignation and Removal; Appointment of Successor Trustee 
 (a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign with respect to the Notes by giving written notice of resignation
to the Issuer and (i) if any Notes are then Outstanding, by giving notice of such resignation to the Holders thereof, by publication at least once in an Authorized Newspaper in the Borough of Manhattan, The City of New York, and at least once
in an Authorized Newspaper in London (and, if required by Section 3.8, at least once in an Authorized Newspaper in Luxembourg), (ii) if any Notes affected are then Outstanding, by mailing notice of such resignation to the Holders thereof
who have filed their names and addresses with the Trustee pursuant to §313(c)(2) of the Trust Indenture Act of 1939 at such addresses as were so furnished to the Trustee and (iii) by mailing notice of such resignation to the Holders of
then Outstanding Notes at their addresses as they shall appear on the registry books. Upon receiving such notice of resignation, the Issuer shall promptly appoint a successor trustee or trustees by written instrument in duplicate, executed by
authority of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee or trustees. If no successor trustee shall have been so appointed and have accepted appointment
within 30 days after the mailing of such notice of resignation, the resigning trustee may petition any court of competent jurisdiction at the expense of the Issuer for the appointment of a successor trustee, or any Holder who has been a bona fide
Holder of a Note or Notes for at least six months may, subject to the provisions of Section 4.12, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 
 (b) In case at any time any of the
following shall occur: 
 (i) the Trustee shall fail to comply with the provisions of §310(b) of the Trust Indenture Act
of 1939 with respect to the Notes after written request therefor by the Issuer or by any Holder who has been a bona fide Holder of a Note or Notes for at least six months; or 
  

 36 

 (ii) the Trustee shall cease to be eligible in accordance with the provisions of §
310(a) of the Trust Indenture Act of 1939 and shall fail to resign after written request therefor by the Issuer or by any Holder; or 
 (iii) the Trustee shall become incapable of acting with respect to the Notes, or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Trustee or of its property shall be appointed, or any public officer shall take
charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; 
 then, in any such case, the
Issuer may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor
trustee, or, subject to § 315(e) of the Trust Indenture Act of 1939, any Holder who has been a bona fide Holder of a Note or Notes for at least six months may on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. If an
instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee being removed may petition, at the expense of the Issuer, any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Notes. 
 (c) The Holders of a majority in aggregate principal
amount of the Notes Outstanding may at any time remove the Trustee with respect to the Notes and appoint a successor trustee with respect to the Notes by delivering to the Trustee so removed, to the successor trustee so appointed and to the Issuer
the evidence provided for in Section 6.1 of the action in that regard taken by the Holders. 
 (d) Any resignation or removal of the
Trustee and any appointment of a successor trustee pursuant to any of the provisions of this Section 5.9 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 5.10 
 Section 5.10 Acceptance and Appointment of Successor Trustee. 
 Any successor trustee appointed as provided in Section 5.9 shall execute and deliver to the Issuer and to its predecessor trustee an instrument
accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee with respect to the Notes shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested
with all rights, powers, duties and obligations with respect to the Notes of its predecessor hereunder, with like effect as if originally named as trustee for such Notes hereunder; but, nevertheless, on the written request of the Issuer or of the
successor trustee, upon payment of its charges then unpaid, the trustee ceasing to act shall, subject to Section 9.4, pay over to the successor trustee all moneys at the time held by it hereunder and 
  

 37 

 shall execute and deliver an instrument transferring to such successor trustee all such rights, powers, duties and
obligations. Upon request of any such successor trustee, the Issuer shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to
act shall, nevertheless, retain a prior claim upon all property or funds held or collected by such trustee to secure any amounts then due it pursuant to the provisions of Section 5.6. 
 Upon acceptance of appointment by any successor trustee as provided in this Section 5.10, the issuer shall give notice thereof (a) if any Notes
are then Outstanding, to the Holders thereof, by publication of such notice at least once in an Authorized Newspaper in the Borough of Manhattan, The City of New York and at least once in an Authorized Newspaper in London (and, if required by
Section 3.8, at least once in an Authorized Newspaper in Luxembourg), (b) if any Notes are then Outstanding, to the Holders thereof who have filed their names and addresses with the Trustee pursuant to § 313(c)(2) of the Trust
Indenture Act of 1939, by mailing such notice to such Holders at such addresses as were so furnished to the Trustee (and the Trustee shall make such information available to the Issuer for such purpose) and (c) to the Holders of Registered
Notes, by mailing such notice to such Holders at their addresses as they shall appear on the registry books. If the acceptance of appointment is substantially contemporaneous with the resignation, then the notice called for by the preceding sentence
may be combined with the notice called for by Section 5.9. If the Issuer fails to give such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be given at the
expense of the Issuer. 
 Section 5.11 Merger, Conversion, Consolidation or Succession to Business of Trustee.

 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided that
such corporation shall be eligible under the provisions of Section 5.8, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. 
 In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated
but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee and deliver such Notes so authenticated; and, in case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificate shall have the full force which it is anywhere in the Notes or in
this Indenture provided that the certificate of the Trustee shall have; provided, that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only
to its successor or successors by merger, conversion or consolidation. 
  

 38 

 Section 5.12 Appointment of Authenticating Agent. 
 As long as any Notes remain Outstanding, the Trustee may, by an instrument in writing, appoint with the approval of the Issuer an authenticating agent
(the “Authenticating Agent”) which shall be authorized to act on behalf of the Trustee to authenticate Notes, including Notes issued upon exchange, registration of transfer, partial redemption or pursuant to Section 2.7. Notes
authenticated by such Authenticating Agent shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee. Whenever reference is made in this Indenture to the authentication
and delivery of Notes by the Trustee or to the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of
authentication executed on behalf of the Trustee by such Authenticating Agent. Such Authenticating Agent shall at all times be a corporation organized and doing business under the laws of the United States of America or of any State, authorized
under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000 (determined as provided in Section 5.8 with respect to the Trustee) and subject to supervision or examination by Federal or State
authority. 
 Any corporation into which any Authenticating Agent may be merged or converted, or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which any Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency business of any Authenticating Agent, shall continue to be the
Authenticating Agent with respect to the Notes without the execution or filing of any paper or any further act on the part of the Trustee or such Authenticating Agent. 
 Any Authenticating Agent may at any time, and if it shall cease to be eligible shall, resign by giving written notice of resignation to the Trustee and to the Issuer. The Trustee may at any time terminate the agency
of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Issuer. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease
to be eligible in accordance with the provisions of this Section 5.12 , the Trustee may upon receipt of an Issuer Order appoint a successor Authenticating Agent and the Issuer shall provide notice of such appointment to all Holders of Notes in
the manner and to the extent provided in Section 5.10. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all rights, powers, duties and responsibilities of its predecessor hereunder, with
like effect as if originally named as Authenticating Agent. The Issuer agrees to pay to the Authenticating Agent from time to time reasonable compensation. The Authenticating Agent for the Notes shall have no responsibility or liability for any
action taken by it as such at the direction of the Trustee. 
 Sections 5.2, 5.3, 5.4, 5.6, 5.8 and 6.3 shall be applicable to any
Authenticating Agent. 
 Section 5.13 Preferential Collection of Claims Against Issuer. 
 The Trustee shall comply with § 311(a) of the Trust Indenture Act of 1939, excluding any creditor relationship listed in § 311(b) of the Trust
Indenture Act of 1939. A Trustee who has resigned or has been removed shall be subject to the Trust Indenture Act of 1939 to the extent indicated therein.

 ARTICLE SIX 
 CONCERNING THE HOLDERS 
 Section 6.1 Evidence of Action Taken by Holders.

 Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken
by a specified percentage in principal amount of the Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Holders in person or by an agent duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee. Proof of execution of any instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Sections 5.1 and 5.2) conclusive in favor of the Trustee, the Issuer and the Guarantor, if made in the manner provided in this Article Six. 
 Section 6.2 Proof of Execution of Instruments and of Holding of Notes. 
 Subject to Sections 5.1 and 5.2, the execution of any instrument by a Holder or his agent or proxy may be proved in the following manner: 
 (i) the fact and date of the execution by any Holder of any instrument may be proved by the certificate of any notary public or other
officer of any jurisdiction authorized to take acknowledgments of deeds or administer oaths that the Person executing such instruments acknowledged to him the execution thereof, or by an affidavit of a witness to such execution sworn to before any
such notary or other such officer. Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute sufficient proof of the authority of the Person executing the same. The fact
of the holding by any Holder of a Note, and the identifying number of such Note and the date of his holding the same, may be proved by the production of such Note or by a certificate executed by any trust company, bank, banker or recognized
securities dealer wherever situated satisfactory to the Trustee, if such certificate shall be deemed by the Trustee to be satisfactory. Each such certificate shall be dated and shall state that on the date thereof a Note bearing a specified
identifying number was deposited with or exhibited to such trust company, bank, banker or recognized securities dealer by the Person named in such certificate. Any such certificate may be issued in respect of one or more Notes specified therein. The
holding by the Person named in any such certificate of any Notes specified therein shall be presumed to continue for a period of one year from the date of such certificate unless at the time of any determination of such holding (1) another
certificate bearing a later date issued in respect of the same Notes shall be produced, or (2) the Note specified in such certificate shall be produced by some other Person, or (3) the Note specified in such certificate shall have ceased
to be Outstanding. The fact and date of the execution of any such instrument and the amount and numbers of Notes held by the Person so executing such instrument and the amount and numbers of any Note or Notes may also be proven in accordance with
such reasonable rules and regulations as may be prescribed by the Trustee or in any other manner which the Trustee may deem sufficient. 
  

 40 

 (ii) The ownership of Notes shall be proved by the Security Register or by a certificate
of the Registrar. 
 Section 6.3 Holders to be Treated as Owners. 
 The Issuer, the Guarantor, the Trustee and any agent of the Issuer, the Guarantor or the Trustee may deem and treat the Person in whose name any Note
shall be registered upon the Note register as the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of
the principal of and, subject to the provisions of this Indenture, interest on such Note and for all other purposes; and neither the Issuer, the Guarantor nor the Trustee nor any agent of the Issuer, the Guarantor or the Trustee shall be affected by
any notice to the contrary. The Issuer, the Guarantor, the Trustee and any agent of the Issuer, the Guarantor or the Trustee may treat the Holder of any Note as the absolute owner of such Note (whether or not such Note shall be overdue) for the
purpose of receiving payment thereof or on account thereof and for all other purposes and neither the Issuer, the Guarantor, the Trustee, nor any agent of the Issuer, the Guarantor or the Trustee shall be affected by any notice to the contrary. All
such payments so made to any such Person, or upon his order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Note. 
 Section 6.4 Notes Owned by Issuer Deemed Not Outstanding. 
 In determining whether the Holders of the requisite aggregate principal amount of Outstanding Notes have concurred in any direction, consent or waiver
under this Indenture, Notes which are owned by the Issuer, the Guarantor or any other obligor on the Notes with respect to which such determination is being made or by any Person directly or indirectly controlling or controlled by or under direct or
indirect common control with the Issuer, the Guarantor or any other obligor on the Notes with respect to which such determination is being made shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except
that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver only Notes which the Trustee knows are so owned shall be so disregarded. Notes so owned which have been pledged in good
faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Notes and that the pledgee is not the Issuer, the Guarantor or any other obligor upon the
Notes or any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer, the Guarantor or any other obligor on the Notes. In case of a dispute as to such right, the advice of counsel shall
be full protection in respect of any decision made by the Trustee in accordance with such advice. Upon request of the Trustee, the Issuer shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any,
known by the Issuer to be owned or held by or for the account of any of the above-described Persons; and, subject to Sections 5.1 and 5.2, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts
therein set forth and of the fact that all Notes not listed therein are Outstanding for the purpose of any such determination. 
  

 41 

 Section 6.5 Right of Revocation of Action Taken. 
 At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 6. 1, of the taking of any action by the Holders of the
percentage in aggregate principal amount of the Notes, specified in this Indenture in connection with such action, any Holder the serial number of which is shown by the evidence to be included among the serial numbers of the Notes the Holders of
which have consented to such action may, by filing written notice at the Corporate Trust Office and upon proof of holding as provided in this Article Six, revoke such action so far as concerns such Note. Except as aforesaid any such action taken by
the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor or on registration of transfer thereof, irrespective of whether
or not any notation in regard thereto is made upon any such Note. Any action taken by the Holders of the percentage in aggregate principal amount of the Notes, specified in this Indenture in connection with such action shall be conclusively binding
upon the Issuer, the Guarantor, the Trustee and the Holders of all the Notes affected by such action. 
 ARTICLE SEVEN 
 AMENDMENTS

Amendments and Supplements Without Consent of Holders. 
 The Issuer, when authorized by a resolution of its Board of Directors
(which resolution may provide general terms or parameters for such action and may provide that the specific terms of such action may be determined in accordance with or pursuant to an Officers’ Certificate), and the Trustee may from time to
time and at any time amend or supplement this Indenture for one or more of the following purposes: 
 (a) to convey, transfer, assign,
mortgage or pledge to the Trustee as security for the Notes any property or assets; 
 (b) to evidence the succession of another Person to

 (c) to add to the covenants of the Issuer such further covenants, restrictions, conditions or provisions as the Issuer and the Trustee shall consider to be for the protection of the Holders of Notes, and to make the
occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions, conditions or provisions an Event of Default permitting the enforcement of all or any of the several remedies provided in this Indenture as
herein set forth; provided, that in respect of any such additional covenant, restriction, condition or provision such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or longer than that
allowed in the case of other defaults) or may provide for an immediate enforcement upon such an Event of Default or may limit the 
  

 42 

 remedies available to the Trustee upon such an Event of Default or may limit the right of the Holders of a majority in
aggregate principal amount of the Notes to waive such an Event of Default; 
 (d) to cure any ambiguity or to correct or supplement any
provision contained herein or in any supplemental indenture which may be defective or inconsistent with any other provision contained herein or in any supplemental indenture, or to make any other provisions as the Issuer may deem necessary or

 (e) to provide for
the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the date hereof;

 (g) to

of the trusts hereunder by more than one trustee, pursuant to the requirements of Section 5.10. 
 The Trustee is hereby authorized to
join with the Issuer and the Guarantor in the execution of any such amendment or supplement, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or
pledge of any property thereunder, but the Trustee shall not be obligated to enter into any such amendment or supplement which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any amendment or supplement to this Indenture authorized by the provisions of this Section may be executed without the consent of the Holders of any of
the Notes at the time Outstanding, notwithstanding any of the provisions of Section 7.2. 
 Section 7.2 Amendments and
Supplements With Consent of Holders 
 With the consent (evidenced as provided in Article Six) of the Holders of not less than a
majority in aggregate principal amount of the Notes at the time Outstanding, the Issuer, when authorized by a resolution of its Board of Directors (which resolution may provide general terms or parameters for such action and may provide that the
specific terms of such action may be determined in accordance with or pursuant to an Issuer Order), the Guarantor and the Trustee may, from time to time and at any time, amend or supplement this Indenture for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of this Indenture or of any amendment or supplement hereto or of modifying in any manner the rights of the Holders of the Notes; provided, that no such amendment or supplement shall
(a) extend the final maturity of any Note, or reduce the principal amount thereof, or reduce the rate or extend 
  

 43 

 the time of payment of interest thereon, or reduce any amount payable on redemption thereof, or make the principal
thereof (including any amount in respect of original issue discount) or interest thereon payable in any coin or currency other than that provided in the Notes or in accordance with the terms thereof, or impair or affect the right of any Holder to
institute suit for the payment thereof or, if the Notes provide therefor, any right of repayment at the option of the Holder, in each case without the consent of the Holder of each Note so affected, or (b) reduce the aforesaid percentage of
Notes, the consent of the Holders of which is required for any such amendment or supplement, without the consent of the Holders of each Note so affected. 
 Upon the request of the Issuer, accompanied by a copy of a resolution of the Board of Directors (which resolution may provide general terms or parameters for such action and may provide that the specific terms of such
action may be determined in accordance with or pursuant to an Issuer Order) certified by the secretary or an assistant secretary of the Issuer authorizing the execution of any such amendment or supplement, and upon the filing with the Trustee of
evidence of the consent of the Holders of the Notes as aforesaid and other documents, if any, required by Section 6.1, the Trustee shall join with the Issuer and the Guarantor in the execution of such amendment or supplement unless such
amendment or supplement affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amendment or supplement.

 It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment or
supplement to this Indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
 Promptly after the execution
by the Issuer, the Guarantor and the Trustee of any amendment or supplement to this Indenture pursuant to the provisions of this Section, the Trustee shall give notice thereof (i) to the Holders of then Outstanding Registered Notes by mailing a
notice thereof by first-class mail to such Holders at their addresses as they shall appear on the Note register, (ii) if any Notes are then Outstanding, to the Holders thereof who have filed their names and addresses with the Trustee pursuant
to § 313(c)(2) of the Trust Indenture Act of 1939, by mailing a notice thereof by first-class mail to such Holders at such addresses as were so furnished to the Trustee and (iii) if any Notes are then Outstanding, to all Holders thereof,
by publication of a notice thereof at least once in an Authorized Newspaper in the Borough of Manhattan, The City of New York, and in each case such notice shall set forth in general terms the substance of such amendment or supplement. Any failure
of the Issuer to give such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment or supplement. 
 Section 7.3 Effect of Amendment and Supplement to this Indenture. 
 Upon the execution of
any amendment or supplement to this Indenture pursuant to the provisions hereof, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and
immunities under this Indenture of the Trustee, the Issuer, the Guarantor and the Holders of Notes shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and
conditions of any such amendment or supplement shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

 The Issuer shall not consolidate with or merge into any other Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, unless: 
 (i) the Person formed by such consolidation or into which the Issuer is merged or the Person which acquires by conveyance, transfer or
lease the properties and assets of the Issuer substantially as an entirety shall expressly assume, by a supplemental indenture hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the
principal of and interest on all the Notes, according to their tenor, and the performance of every covenant of this Indenture on the part of the Issuer to be performed or observed; 
 (ii) immediately after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time, or both,
would become an Event of Default, shall have happened and be continuing; 
 (iii) the Issuer has delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel each stating that such consolidation, merger, conveyance, transfer or lease and such supplemental indenture comply with this Article Eight and that all conditions precedent herein provided for
relating to such transaction have been complied with; 
  

 45 

 (iv) the Issuer has delivered to the Trustee such other documents as the Trustee may, in
its discretion, reasonably require; and 
 (v) if the Issuer is not the continuing Person, then the Guarantor shall confirm
that its guarantee shall continue to apply to the obligations under the Note and this Indenture. 
 Section 8.2 Successor
Person Substituted. 
 In case of any such consolidation, merger, sale, lease or conveyance, and following such an assumption by the
successor Person, such successor Person shall succeed to and be substituted for the Issuer, with the same effect as if it had been named herein. Such successor Person may cause to be signed, and may issue either in its own name or in the name of the
Issuer prior to such succession any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Issuer and delivered to the Trustee; and, upon the order of such successor Person, instead of the Issuer, and subject to
all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Notes which previously shall have been signed and delivered by the officers of the Issuer to the Trustee for authentication,
and any Notes which such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All of the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes
theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. 
 In case of any such consolidation, merger, sale, lease or conveyance such changes in phrasing and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 
 In the event of any such sale or conveyance (other than a conveyance by way of lease) the Issuer or any successor Person which shall theretofore have
become such in the manner described in this Article Eight shall be discharged from all obligations and covenants under this Indenture and the Notes and may be liquidated and dissolved.

 SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS

 Section 9.1 Satisfaction and Discharge of Indenture. 
 (a) If at any time (a) the Issuer shall have paid or caused to be paid the principal of and interest on all the Notes Outstanding hereunder (other
than Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.7) as and when the same shall have become due and payable, or (b) the Issuer shall have delivered to the Trustee for
cancellation all Notes theretofore authenticated (other than any Notes which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.7) or (c) in the case of Notes where the exact or
maximum amount of principal of and interest due on which can be determined at the time of making the deposit referred to in clause (ii) below, (i) all the Notes not theretofore delivered to the Trustee for cancellation shall 
  

 46 

 have become due and payable, or are by their terms to become due and payable within one year or are to be called for
redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and (ii) the Issuer shall have irrevocably deposited or caused to be deposited with the Trustee as trust funds the entire amount
in cash (other than moneys repaid by the Trustee or any paying agent to the Issuer in accordance with Section 9.4) or direct obligations of the United States of America, backed by its full faith and credit (“U.S. Government
Obligations”), maturing as to principal and interest at such times and in such amounts as will insure the availability of cash, or a combination thereof, sufficient in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee, to pay (A) the principal of and interest on all Notes on each date that such principal or interest is due and payable and (B) any mandatory sinking fund
payments applicable to Notes on the dates on which such payments are due and payable in accordance with the terms of the Indenture and the Notes; and if, in any such case, the Issuer shall also pay or cause to be paid all other sums payable
hereunder by the Issuer with respect to the Notes, then this Indenture with respect to the Notes shall cease to be of further effect (except as to (i) rights of registration of transfer and exchange of Notes and the Issuer’s right of
optional redemption, if any, (ii) substitution of mutilated, defaced, destroyed, lost or stolen Notes, (iii) rights of Holders of Notes to receive payments of principal thereof and interest thereon, upon the original stated due dates
therefor (but not upon acceleration), and remaining rights of the Holders to receive mandatory sinking fund payments, if any, (iv) the rights, obligations, duties and immunities of the Trustee hereunder, and (v) the rights of the Holders
of Notes as beneficiaries hereof with respect to the property so deposited with the Trustee payable to all or any of them) and the Trustee, on demand of the Issuer accompanied by an Officers’ Certificate and an Opinion of Counsel and at the
cost and expense of the Issuer, shall execute proper instruments acknowledging such satisfaction of and discharging this Indenture with respect to the Notes; provided that the rights of Holders of the Notes to receive amounts in respect of principal
of and interest on the Notes held by them shall not be delayed longer than required by then-applicable mandatory rules or policies of any securities exchange upon which the Notes are listed. The Issuer agrees to reimburse the Trustee for any costs
or expenses thereafter reasonably and properly incurred and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Notes. 
 (b) In addition to discharge of the Indenture pursuant to the next preceding paragraph, in the case of Notes the exact or maximum amounts (including the
currency of payment) of principal of and interest due on which can be determined at the time of making the deposit referred to in clause (a) below, the Issuer shall be deemed to have paid and discharged the entire indebtedness on all the Notes
on the 91st day after the date of the deposit referred to in subparagraph (a) below, and the provisions of this Indenture with respect to the Notes shall no longer be in effect (except as to (i) rights of registration of transfer and
exchange of Notes and the Issuer’s right of optional redemption, if any, (ii) substitution of mutilated, defaced, destroyed, lost or stolen Notes, (iii) rights of Holders of Notes to receive payments of principal thereof and interest

request, execute proper instruments acknowledging the same, if: 
  

 47 

 (i) with reference to this provision the Issuer has irrevocably deposited or caused to be
irrevocably deposited with the Trustee as trust funds in trust, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Notes (i) cash in an amount, or (ii) U.S. Government Obligations, maturing as
to principal and interest at such times and in such amounts as will insure the availability of cash or (iii) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay (A) the principal of and interest on all Notes on each date that such principal or interest is due and payable and (B) any mandatory sinking fund payments on the dates on which
such payments are due and payable in accordance with the terms of the Indenture and the Notes; 
 (ii) such deposit will not
result in a breach or violation of, or constitute a default under, any agreement or instrument to which the Issuer is a party or by which it is bound; 
 (iii) the Issuer has delivered to the Trustee an Opinion of Counsel based on the fact that (x) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (y) since
the date hereof, there has been a change in the applicable Federal income tax law, in either case to the effect that, and such opinion shall confirm that, the Holders of the Notes will not recognize income, gain or loss for Federal income tax
purposes as a result of such deposit, defeasance and discharge and will be subject to Federal income tax on the same amounts, in the same manner and at the same times, as would have been the case if such deposit, defeasance and discharge had not
occurred; 
 (iv) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each
stating that all conditions precedent provided for relating to the defeasance contemplated by this provision have been complied with;

subsections 4.1(d) and (e) are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period); and

 (vi) Such covenant defeasance contemplated by this provision shall not cause any Notes then listed on any registered
national securities exchange under the Securities Exchange Act of 1934, as amended, to be delisted. 
 (c) In the case of Notes the exact or
maximum amounts (including the currency of payment) of principal of and interest due on which can be determined at the time of making the deposit referred to in clause (a) below, the Issuer shall be released from its obligations under Sections
3.4, 3.5 and 8.1 with respect to the Outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “covenant defeasance”). For this purpose, such covenant defeasance means that, with respect to the
Outstanding Notes, the Issuer 
  

 48 

 may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in such
Sections, whether directly or indirectly by reason of any reference elsewhere herein to such Sections or by reason of any reference in such Sections to any other provision herein or in any other document and such omission to comply shall not
constitute an Event of Default under Section 4.1, but the remainder of this Indenture and such Notes shall be unaffected thereby. The following shall be the conditions to application of this subsection (c) of this Section 9.1:

 (i) The Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose
of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Notes, (i) cash in an amount, or (ii) U.S. Government Obligations maturing as to principal and interest at
such times and in such amounts as will insure the availability of cash or (iii) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay (A) the principal of and interest on all Notes on each date that such principal and interest is due and payable and (B) any mandatory sinking fund payments applicable to such Notes on the day on which such
payments are due and payable in accordance with the terms of the Indenture and the Notes; 
 (ii) No Event of Default or event
which with notice or lapse of time or both would become an Event of Default with respect to the Notes shall have occurred and be continuing on the date of such deposit or, insofar as subsections 4.1(d) and (e) are concerned, at any time during
the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period); 
 (iii) Such covenant defeasance shall not cause the Trustee to have a conflicting interest as described in §310 of the Trust Indenture
Act of 1939 with respect to any securities of the Issuer; 
 (iv) Such covenant defeasance shall not result in a breach or
violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Issuer is a party or by which it is bound; 
 (v) Such covenant defeasance shall not cause any Notes then listed on any registered national securities exchange under the Securities Exchange Act of 1934, as amended, to be delisted; 
 (vi) The Issuer shall have delivered to the Trustee an Officers’ Certificate and Opinion of Counsel to the effect that the Holders of
the Notes will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the
case if such covenant defeasance had not occurred; and

Opinion of Counsel, each stating that all conditions precedent provided for relating to the covenant defeasance contemplated by this provision have been complied with.

acting as its own paying agent), to the Holders of the Notes for the payment or redemption of which such moneys have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest; but such money need not be
segregated from other funds except to the extent required by law. 
 Section 9.3 Repayment of Moneys Held by Paying
Agent. 
 In connection with the satisfaction and discharge of this Indenture with respect to Notes, all moneys then held by any
paying agent under the provisions of this Indenture with respect to the Notes shall, upon demand of the Issuer, be repaid to it or paid to the Trustee and thereupon such paying agent shall be released from all further liability with respect to such
moneys. 
 Section 9.4 Return of Moneys Held by Trustee and Paving Agent Unclaimed for Two Years. 
 Any moneys deposited with or paid to the Trustee or any paying agent for the payment of the principal of or interest on any Note and not applied but
remaining unclaimed for two years after the date upon which such principal or interest shall have become due and payable, shall, upon the written request of the Issuer and unless otherwise required by mandatory provisions of applicable escheat or
abandoned or unclaimed property law, be repaid to the Issuer by the Trustee or such paying agent, and the Holder of the Notes shall, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property laws,
thereafter look only to the Issuer for any payment which such Holder may be entitled to collect, and all liability of the Trustee or any paying agent with respect to such moneys shall thereupon cease; provided, however, that the Trustee or such
paying agent, before being required to make any such repayment with respect to moneys deposited with it for any payment (a) in respect of Registered Notes shall at the expense of the Issuer, mail by first-class mail to Holders of such Notes at
their addresses as they shall appear on the Note register, and (b) shall at the expense of the Issuer cause to be published once, in an Authorized Newspaper in the Borough of Manhattan, The City of New York and once in an Authorized Newspaper
in London, notice, that such moneys remain and that, after a date specified therein, which shall not be less than 30 days from the date of such mailing or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer.

 The Trustee shall deliver to the Issuer from time to time upon Issuer Order any U.S. Government Obligations or
money held by it as provided in Section 9.1 which, as expressed in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may include the
applicable opinion delivered to the Trustee pursuant to Section 9. 1), are then in excess of the amount thereof which then would have been required to be deposited for the purpose for which such obligations or money were deposited or received.

 ARTICLE ELEVEN 
 REDEMPTION AND PREPAYMENT 
 Section 11.1 Notices to Trustee. 
 If the Issuer elects to redeem
Notes pursuant to the optional redemption provisions of Section 11.7 hereof, it shall furnish to the Trustee, at least 45 days but not more than 90 days before a redemption date (or such shorter period as allowed by the Trustee), an
Officers’ Certificate setting forth (i) the applicable section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the
redemption price. 
 Section 11.2 Selection of Notes to Be Redeemed. 
 If less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed among the Holders of the Notes in
compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or in accordance with any other method the Trustee deems fair and
appropriate (and in compliance with applicable legal requirements). However, no Notes of a principal amount of $1,000 or less shall be redeemed in part, and, if a partial redemption of Notes is made with the proceeds of a public offering of common
equity securities of the Issuer, selection of the Notes or portions of the Notes for redemption shall be made by the Trustee only on a proportional basis or on as nearly a proportional basis as is practicable (except as required by the procedures of
the Depositary), unless that method is otherwise prohibited. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the
redemption date by the Trustee from the Outstanding Notes not previously called for redemption. 
  

 55 

 The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption and, in the
case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or integral multiples of $1,000, except that if all of the Notes of a Holder are to be
redeemed, the entire Outstanding amount of Notes held by such Holder, even if not an integral multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption
also apply to portions of Notes called for redemption. 
 Section 11.3 Notice of Redemption. 
 At least 30 days but not more than 60 days prior to a redemption date, the Issuer shall mail or cause to be mailed, by first class mail, a notice of
redemption to each Holder whose Notes are to be redeemed at such Holder’s address appearing in the securities register maintained in respect of the Notes by the Registrar (the “Security Register”). 
 The notice shall identify the Notes to be redeemed (including the CUSIP number) and shall state: 
 (a) the redemption date; 
 (b) The
appropriate calculation of the redemption price, but need not include the redemption price itself. The actual redemption price, calculated as described above, shall be set forth in an Officers’ Certificate delivered to the Trustee no later than
two (2) Business Days prior to the redemption date unless clause (b) of the definition of “Comparable Treasury Price” is applicable, in which case such Officer’s Certificate should be delivered on the redemption date;

 (c) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption
date upon surrender of such Note, if applicable, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note; 
 (d) the name and address of the Paying Agent; 
 (e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
 (f) that, unless
the Issuer defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; 
 (g) the applicable section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and 
 (h) that
no representation is made as to the correctness of the CUSIP and/or ISIN numbers, if any, listed in such notice or printed on the Notes. 
 At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at its expense; provided, however, that the Issuer shall have delivered to the 
  

 56 

 Trustee, at least 45 days (or such shorter period allowed by the Trustee) prior to the redemption date, an Officers’
Certificate requesting that the Trustee give such notice (in the name and at the expense of the Issuer) and setting forth the information to be stated in such notice as provided in this Section 11.3. 
 Section 11.4 Effect of Notice of Redemption. 
 Once notice of redemption is mailed in accordance with Section 11.3 hereof, Notes called for redemption shall become irrevocably due and payable on the redemption date at the redemption price. A notice of
redemption may not be conditional. 
 Section 11.5 Deposit of Redemption Price. 
 On or prior to 11:00 a.m. Eastern time on the Business Day prior to any redemption date, the Issuer shall deposit with the Trustee or with the Paying
Agent money sufficient to pay the redemption price of and, if applicable, accrued and unpaid interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly, and in any event within two (2) Business Days after
the redemption date, return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption price of, and, accrued and unpaid interest, if any, on all Notes to be
redeemed. 
 If the Issuer complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to
accrue on Notes or portions of Notes called for purchase or redemption in accordance with Section 2.8(d) hereof, whether or not such Notes are presented for payment. If a Note is redeemed on or after a Regular Record Date but on or prior to the
related Interest Payment Date, then any accrued and unpaid interest, if any, shall be paid to the Person in whose name such Note was registered at the close of business on such Regular Record Date. If any Note called for redemption shall not be so
paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal from the redemption date until such principal is paid, and to the extent lawful on any
interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 
 Section 11.6 Notes Redeemed in Part. 
 Upon surrender of a Note that is redeemed in part,
the Issuer shall issue and, upon the Issuer’s written request, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered. 
 Section 11.7 Optional Redemption. 
 (a) The Notes will be redeemable as a whole or in part, at the option of the Issuer at any time at a redemption price equal to the greater of (i) 100% of the principal amount of such Notes and (ii) the sum
of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus
         basis points, plus in each case accrued interest thereon to the date of redemption.

Sections 11.1 through 11.6 hereof. 
 Section 11.8 Mandatory Redemption.

 ARTICLE TWELVE 
 GUARANTEE

 Section 12.1 Unconditional Guarantee. 
 (a) For value received, the Guarantor hereby fully, unconditionally and absolutely guarantees (the “Guarantee”) to the Holders and to the
Trustee the due and punctual payment of the principal of, and premium, if any, and interest on the Notes and all other amounts due and payable under this Indenture and the Notes by the Issuer, when and as such principal, premium, if any, and
interest shall become due and payable, whether at the stated maturity or by declaration of acceleration, call for redemption or otherwise, according to the terms of the Notes and this Indenture, subject to the limitations set forth in
Section 12.3. 
 (b) Failing payment when due of any amount guaranteed pursuant to the Guarantee, for whatever reason, the Guarantor
will be obligated to pay the same immediately. The Guarantee hereunder is intended to be a general, unsecured, senior obligation of the Guarantor and will rank pari passu in right of payment with all Indebtedness of the Guarantor that is not, by its
terms, expressly subordinated in right of payment to the Guarantee. The Guarantor hereby agrees that its obligations hereunder shall be full, unconditional and absolute, irrespective of the validity, regularity or enforceability of the Notes, the
Guarantee or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, the Guarantor, or any
action to enforce the same or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of the Guarantor. The Guarantor hereby agrees that in the event of a default in payment of the principal of, or premium,
if any, or interest on the Notes, whether at the stated maturity or by declaration of acceleration, call for redemption or otherwise, legal proceedings may be instituted by the Trustee on behalf of the Holders or, subject to Section 4.6, by the
Holders, on the terms and conditions set forth in this Indenture, directly against the Guarantor to enforce the Guarantee without first proceeding against the Partnership. 
 (c) The obligations of the Guarantor under this Article Twelve shall be as aforesaid full, unconditional and absolute and shall not be impaired,
modified, released or limited by any occurrence or condition whatsoever, including, without limitation, (A) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations
and liabilities of the Issuer, the Guarantor contained in the Notes or this Indenture, (B) any impairment, modification, release or limitation of the liability of the Issuer, the Guarantor, or any of their estates in bankruptcy, or any remedy
for the enforcement thereof, resulting from the operation of any present or future provision of any applicable Bankruptcy 
  

 58 

 Law, as amended, or other statute or from the decision of any court, (C) the assertion or exercise by the Issuer,
the Guarantor, or the Trustee of any rights or remedies under the Notes or this Indenture or their delay in or failure to assert or exercise any such rights or remedies, (D) the assignment or the purported assignment of any property as security
for the Notes, including all or any part of the rights of the Issuer or the Guarantor under this Indenture, (E) the extension of the time for payment by the Issuer, the Guarantor of any payments or other sums or any part thereof owing or
payable under any of the terms and provisions of the Notes or this Indenture or of the time for performance by the Issuer or the Guarantor of any other obligations under or arising out of any such terms and provisions or the extension or the renewal
of any thereof, (F) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Issuer or the Guarantor set forth in this Indenture, (G) the voluntary or involuntary liquidation, dissolution,
sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or
other similar proceeding affecting, the Issuer or the Guarantor or any of their respective assets, or the disaffirmance of the Notes, the Guarantee or this Indenture in any such proceeding, (H) the release or discharge of the Issuer or the
Guarantor from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law, (I) the unenforceability of the Notes, the Guarantee or this Indenture or (J) any other
circumstances (other than payment in full or discharge of all amounts guaranteed pursuant to the Guarantee) which might otherwise constitute a legal or equitable discharge of a surety or guarantor. 
 (d) The Guarantor hereby (A) waives diligence, presentment, demand of payment, filing of claims with a court in the event of the merger, insolvency
or bankruptcy of the Issuer or the Guarantor and all demands whatsoever, (B) acknowledges that any agreement, instrument or document evidencing the Guarantee may be transferred and that the benefit of its obligations hereunder shall extend to
each holder of any agreement, instrument or document evidencing the Guarantee without notice to it and (C) covenants that the Guarantee will not be discharged except by complete performance of the Guarantee. The Guarantor further agrees that if
at any time all or any part of any payment theretofore applied by any Person to the Guarantee is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of the Issuer
or the Guarantor the Guarantee shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the Guarantee shall continue to be effective or be reinstated,
as the case may be, as though such application had not been made. 
 (e) The Guarantor shall be subrogated to all rights of the Holders and
the Trustee against the Issuer in respect of any amounts paid by the Guarantor pursuant to the provisions of this Indenture, provided, however, that the Guarantor, shall not be entitled to enforce or to receive any payments arising out of, or based
upon, such right of subrogation until all of the Notes and the Guarantee shall have been paid in full or discharged. 
 Section 12.2 Execution and Delivery of Guarantee. 
 To further evidence the Guarantee set
forth in Section 12.1, the Guarantor hereby agrees that a notation relating to such Guarantee, substantially in the form attached hereto as 
  

 59 

 Annex A, shall be endorsed on each Note entitled to the benefits of the Guarantee authenticated and delivered by the
Trustee and executed by either manual or facsimile signature of an officer of Boardwalk GP. The Guarantor hereby agrees that the Guarantee set forth in Section 12.1 shall remain in full force and effect notwithstanding any failure to endorse on
each Note a notation relating to the Guarantee. If any officer of Boardwalk GP or any Affiliate, whose signature is on this Indenture or a Note no longer holds that office at the time the Trustee authenticates such Note or at any time thereafter,
the Guarantee of such Note shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantor.

 Section 12.3 Limitation on Liability of the Guarantor. 
 The Guarantor and by its acceptance hereof each Holder of a Note entitled to the benefits of the Guarantee hereby confirm that it is the intention of all
such parties that the guarantee by the Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Federal or state law. To effectuate the foregoing intention, the Holders of a Note entitled to the
benefits of the Guarantee and the Guarantor hereby irrevocably agree that the obligations of the Guarantor under its Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of the
Guarantor and to any collections from or payments made by or on behalf of the Guarantor in respect of the obligations of the Guarantor under its Guarantee, result in the obligations of the Guarantor under the Guarantee not constituting a fraudulent
conveyance or fraudulent transfer under Federal or state law. 
 Section 12.4 Release of Guarantor from Guarantee.

 (a) Notwithstanding any other provisions of this Indenture, the Guarantee of the Guarantor may be released upon the terms and subject
to the conditions set forth in this Section 12.4. Provided that no Default shall have occurred and shall be continuing under this Indenture, any Guarantee incurred by the Guarantor pursuant to this Article Twelve shall be unconditionally
released and discharged upon (i) the Issuer’s exercise of its legal defeasance option or its covenant defeasance option in accordance with Article Nine hereof or (ii) the merger of the Guarantor into the Issuer or the liquidation or
dissolution of the Guarantor (in each case to the extent not prohibited by this Indenture) or (iii) following delivery of a written notice of such release or discharge by the Issuer, the Trustee, upon the release or discharge of all guarantees
by the Guarantor of any debt of the Issuer other than obligations arising under this Indenture and any Notes issued hereunder, except a discharge or release by or as a result of payment under such guarantees. 
 (b) The Trustee shall deliver an appropriate instrument evidencing any release of the Guarantor from the Guarantee upon receipt of a written request of
the Issuer accompanied by an Officers’ Certificate and an Opinion of Counsel that the Guarantor is entitled to such release in accordance with the provisions of this Indenture.

 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 1. Interest. Boardwalk Pipelines, LP, a Delaware limited partnership (the “Issuer”), promises to pay interest on the principal amount of
this Note at             % per annum until maturity relating to these Notes. The Issuer shall pay interest semi-annually in arrears in cash on
             and              of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an “Interest Payment Date”). Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from
[            ], 200[    ];provided, however, that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date
referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be
[            ], 200[    ]. The Issuer shall pay interest (including post-petition interest in any proceeding under any 
  

 A-2 

 Bankruptcy Law) on overdue principal and premium, if any, from time to time at a rate that is 1% per annum in excess
of the interest rate then in effect under the Indenture and this Note; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace
periods), from time to time at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. 
 2. Method of Payment. The Issuer shall pay interest on the Notes (except defaulted interest) to the Persons in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on
             or              preceding the Interest Payment Date, even if such Notes are cancelled after such
record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes shall be payable as to principal, premium, if any, and interest at the office or
agency of the Issuer maintained for such purpose, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the Security Register; provided, however, that payment by wire transfer
of immediately available funds shall be required with respect to principal of and interest and premium, if any, on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuer or the Paying
Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 3. Paying Agent and Registrar. Initially, The Bank of New York, the Trustee under the Indenture, shall act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to
any Holder. The Issuer or any of its Subsidiaries may act in any such capacity. 
 4. Indenture. The Issuer issued the Notes under an
Indenture, dated as of November __, 2006 (“Indenture”), among the Issuer, the Guarantor and the Trustee. 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, as amended (15 U.S.Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with
the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 
 5. Optional Redemption.

 (a) The Notes will be redeemable as a whole or in part, at the option of the Issuer at any time at a redemption price equal to the greater
of (i) 100% of the principal amount of such Notes and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Treasury Rate, as defined in the Indenture, plus [            ] basis points, plus in each case accrued interest thereon to the date of
redemption. 
 (b) Any prepayment pursuant to this paragraph shall be made pursuant to the provisions of Sections 11.1 through 11.6 of the

 6. Mandatory Redemption. The Issuer shall not be required to make mandatory redemption or sinking
fund payments with respect to the Notes. 
 7. Notice of Redemption. Notices of redemption shall be mailed at least 30 days but not
more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in integral multiples of $1,000, unless all of the Notes
held by a Holder are to be redeemed. On and after the redemption date interest shall cease to accrue on Notes or portions thereof called for redemption. 
 8. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. This Note shall represent the aggregate principal amount of
Outstanding Notes from time to time endorsed hereon and the aggregate principal amount of Notes represented hereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. The transfer of Notes may be
registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any
taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also,
the Issuer need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 
 9. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes. 
 10. Amendment, Supplement and Waiver. Subject to certain exceptions, the Issuer and the Trustee may amend or supplement the Indenture or the Notes
with the consent of the Holders of at least a majority in principal amount of the Notes then Outstanding, and, subject to Section 4.10 of the Indenture, any existing Default or Event of Default (except a continuing Default or Event of Default
(i) in the payment of principal, premium, if any, interest, if any, on the Notes and (ii) in respect of a covenant or provision which under the Indenture cannot be modified or amended without the consent of the Holder of each Note affected
by such modification or amendment) or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of at least a majority in principal amount of the Notes. Without the consent of any Holder, the Issuer
and the Trustee may amend or supplement the Indenture or the Notes: (a) to convey, transfer, assign, mortgage or pledge to the Trustee as security for the Notes any property or assets; (b) to evidence the succession of another Person to
the Issuer, or successive successions, and the assumption by the successor Person of the covenants, agreements and obligations of the Issuer pursuant to Article Eight of the Indenture; (c) to add to the covenants of the Issuer such further
covenants, restrictions, conditions or provisions as the Issuer and the Trustee shall consider to be for the protection of the Holders of Notes, and to make the occurrence, or the occurrence and continuance, of a default in any such additional
covenants, restrictions, conditions or provisions an Event of Default permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided, that in respect of any such additional covenant,
restriction, condition or provision such supplemental indenture 
  

 A-4 

 may provide for a particular period of grace after default (which period may be shorter or longer than that allowed in
the case of other defaults) or may provide for an immediate enforcement upon such an Event of Default or may limit the remedies available to the Trustee upon such an Event of Default or may limit the right of the Holders of a majority in aggregate
principal amount of the Notes to waive such an Event of Default; (d) to cure any ambiguity or to correct or supplement any provision contained herein or in any supplemental indenture which may be defective or inconsistent with any other
provision contained herein or in any supplemental indenture, or to make any other provisions as the Issuer may deem necessary or desirable, provided that no such action shall materially adversely affect the interests of the Holders of the Notes;
(e) to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture; and (f) to evidence and provide for the acceptance of appointment hereunder by a successor trustee with respect to the Notes
and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee, pursuant to the requirements of Section 5.10 of the
Indenture. 
 11. Defaults and Remedies. Each of the following constitutes an Event of Default with respect to the Notes:
(a) default in the payment of any installment of interest upon any of the Notes as and when the same shall become due and payable, and continuance of such default for a period of 30 days; or (b) default in the payment of all or any part of
the principal on any of the Notes as and when the same shall become due and payable either at maturity, upon any redemption, by declaration or otherwise; or (c) default in the performance, or breach, of any covenant or warranty of the Issuer or
the Guarantor in respect of the Notes (other than a covenant or warranty in respect of the Notes a default in whose performance or whose breach is elsewhere in this Section is specifically dealt with) and continuance of such default or breach for a
period of 60 days after there has been given, by registered or certified mail, to the Issuer and the Guarantor by the Trustee or to the Issuer, the Guarantor and the Trustee by the Holders of at least 25% in aggregate principal amount of the
Outstanding Notes, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or (d) either (1) default in payment of any Indebtedness of
the Issuer, the Guarantor or any Subsidiary of the Issuer within any applicable grace period after final maturity or (2) the acceleration of Indebtedness of the Issuer, the Guarantor or any Subsidiary of the Issuer by the holders thereof
because of a default and, in either case, the total amount of the Indebtedness unpaid or accelerated exceeds $50 million; or (e) the entry of a decree or order by a court having jurisdiction in the premises adjudging the Issuer, the Guarantor
or any Significant Subsidiary as bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Issuer, the Guarantor or any Significant Subsidiary under the
federal bankruptcy law or any other applicable federal or state law, or appointing a receiver, liquidator, assignee, trustee, sequestrator (or other similar official) of the Issuer, the Guarantor or any Significant Subsidiary or for any substantial
part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or (f) the institution by the Issuer, the Guarantor or
any Significant Subsidiary of proceedings to be adjudicated as bankrupt or insolvent or the consent by the Issuer, the Guarantor or any Significant Subsidiary to the institution of bankruptcy or insolvency proceedings against it, or the filing by
the Issuer, the Guarantor or any Significant Subsidiary of a petition or answer or consent seeking reorganization or relief under the federal bankruptcy law or any other applicable 
  

 A-5 

 federal or state law, or the consent by the Issuer or any Significant Subsidiary to the filing of any such petition or to
the appointment of a receiver, liquidator, assignee, trustee, sequestrator (or other similar official) of the Issuer, the Guarantor or any Significant Subsidiary or for any substantial part of its property, or the making by the Issuer, the Guarantor
or any Significant Subsidiary of any general assignment for the benefit of creditors; provided, however, that the occurrence of any of the events described in the foregoing clause (c) of Section 4.1 of the Indenture shall not
constitute an Event of Default if such occurrence is the result of changes in generally accepted accounting principles as recognized by the American Institute of Certified Public Accountants at the date as of which this Indenture is executed and a
certificate to such effect is delivered to the Trustee by the Issuer’s independent public accountants. 
 If an Event of Default
described in clauses (a), (b), (c) or (d) of Section 4.1 of the Indenture occurs and is continuing, then, and in each and every such case, unless the principal of all the Notes shall have already become due and payable, either the
Trustee or the Holders of not less than 25% in aggregate principal amount of all the Notes then Outstanding hereunder, by notice in writing to the Issuer and the Guarantor (and to the Trustee if given by Noteholders), may declare the entire
principal of all of the Notes then Outstanding, and interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable. If an Event of Default described in clause
(e) or (f) of Section 4.1 of the Indenture occurs and is continuing, then and in each and every such case, unless the principal of all the Notes shall have already become due and payable, the entire principal of all of the Notes then
Outstanding, and interest accrued thereon, if any, will become immediately due and payable without any declaration of acceleration or other act on the part of the Trustee or any Holders. 
 The foregoing provisions, however, are subject to the condition that if, at any time after the principal of the Notes shall have been so declared due and
payable or become automatically due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a sum sufficient
to pay all matured installments of interest upon all the Notes and the principal of any and all Notes which shall have become due otherwise than by acceleration (with interest upon such principal and, to the extent that payment of such interest is
enforceable under applicable law, on overdue installments of interest, at the same rate as the rate of interest specified in the Notes to the date of such payment or deposit) and such amount as shall be sufficient to cover reasonable compensation to
the Trustee and each predecessor Trustee and their agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee except as a result of negligence or bad faith, and
if any and all Events of Default under the Indenture, other than the non-payment of the principal of Notes which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as provided herein—then and in every
such case the Holders of a majority in aggregate principal amount of all the Notes then Outstanding, by written notice to the Issuer, the Guarantor and to the Trustee, may waive all defaults with respect to the Notes and rescind and annul such
declaration and its consequences, but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or shall impair any right consequent thereon. 
  

 A-6 

 12. No Recourse. 
 None of Boardwalk GP, the respective general partners of the Issuer and the Guarantor or their respective directors, officers, employees, partners and members, as such, shall have any liability for any obligations of,
the Guarantor or the Issuer under the Notes, the Indenture or the Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting the Securities waives and releases all such
liability. The waiver and release are part of the consideration for issuance of the Securities.

CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption or notices of Offers to Purchase as a convenience to Holders. No representation is made as to the correctness of such numbers either
as printed on the Notes or as contained in any notice of redemption or notice of an offer to purchase and reliance may be placed only on the other identification numbers printed thereon and any such redemption or offer to purchase shall not be
affected by any defect in or omission of such numbers.
