treaties, (ii) an Administrative Action, (iii) any amendment to, clarification of, or change in the official position or the interpretation of any Administrative Action or any interpretation or pronouncement that provides for a

asserted in writing against any other taxpayer that has raised capital through the issuance of securities that are substantially similar to the Notes, in each case of clauses (i), (ii), (iii) and (iv), that occurs on or after the date of

been discontinued, then the Calculation Agent shall consult with an investment bank of national standing to determine whether there is an industry accepted substitute or successor base rate to three-month LIBOR. If, after such consultation, the
Calculation Agent determines that there is an industry accepted substitute or successor base rate, the Calculation Agent shall use such substitute or successor base rate. In such case, the Calculation Agent in its sole discretion may (without
implying a corresponding obligation to do so) also implement changes to the business day convention, the definition of Business Day and LIBOR Business Day, the LIBOR Interest Determination Date and any method for obtaining the substitute or
successor base rate if such rate is unavailable on the relevant Business Day, in a manner that is consistent with industry accepted practices for such substitute or successor base rate. Unless the Calculation Agent determines that there is an
industry accepted substitute or successor base rate as so provided above, the provisions of the following paragraph will apply. 
 If no
rate appears on Reuters Page LIBOR01 on the LIBOR Interest Determination Date, the Calculation Agent shall request that the principal London offices of four major reference banks in the London Inter-Bank Market provide the Calculation Agent with
their offered quotations for deposits in 

  
 5 







 
U.S. dollars in a principal amount of not less than $1,000,000 for the period of three months, commencing on the LIBOR Rate Reset Date, to prime banks in the London Inter-Bank Market at
approximately 11:00 a.m., London time, on that LIBOR Interest Determination Date and in a principal amount that is representative for a single transaction in U.S. dollars in that market at that time. If at least two quotations are provided, then
the Three-Month LIBOR Rate will be the average (rounded, if necessary, to the nearest one-hundredth (0.01) of a percent) of such quotations. If fewer than two quotations are provided, then the
Three-Month LIBOR Rate will be the average (rounded, if necessary, to the nearest one hundredth (0.01) of a percent) of the rates quoted at approximately 11:00 a.m., Eastern time, on the LIBOR Interest Determination Date by three major banks in New
York City selected by the Calculation Agent for loans in U.S. dollars to leading European banks, having a three-month maturity and in a principal amount of not less than $1,000,000. If the banks selected by the Calculation Agent are not providing
quotations in the manner described herein, the Calculation Agent, after consulting such sources as it deems comparable to any of the foregoing quotations or display page, or any such source as it deems reasonable from which to estimate three-month
LIBOR or any of the foregoing lending rates, shall determine the rate for the Quarterly Interest Period following the LIBOR Interest Determination Date in its sole discretion. 

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

Section 1.02 Rules of Construction. 

The following provisions shall be applied wherever appropriate herein: 

(a) any references herein to a particular Section, Article, or Exhibit means a Section or Article of, or an Exhibit to, this
First Supplemental Indenture, unless otherwise expressly stated herein; and

thereof. 
 Section 2.02 Maturity.

Section 2.03 Form. 
 The Notes
and the related Trustee’s certificate of authentication shall be substantially in the form of Exhibit A to this First Supplemental Indenture with such appropriate insertions, omissions, substitutions and other variations as are required or
permitted by the Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as the Issuer may deem appropriate or as may be required or appropriate to comply with any laws or with
any rules made pursuant thereto or with the rules of any securities exchange or automated quotation system on which any of such Notes may be listed or traded, or to conform to general usage, or as may, consistently with the Indenture, be determined
by the officers executing such Notes, as evidenced by their execution thereof. 
 Such Exhibit A is hereby incorporated into this First
Supplemental Indenture. The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this First Supplemental Indenture, and to the extent applicable, the Issuer and the Trustee, by their execution and
delivery of this First Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. 
 The Notes shall be
issued only as Registered Securities. The Notes shall be issued upon original issuance in whole in the form of one or more Global Securities (the “Book-Entry Notes”). Each Book-Entry Note shall represent such of the Outstanding Notes as
shall be specified therein and shall provide that it shall represent the aggregate amount of Outstanding Notes from time to time endorsed thereon and that the aggregate amount of Outstanding Notes represented thereby may from time to time be reduced
or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Book-Entry Note to reflect the amount, or any increase or decrease in the amount, of Outstanding Notes represented thereby shall be made by the Trustee in
accordance with written instructions or such other written form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any Person having a beneficial interest in the Book-Entry Note. The Issuer initially
appoints DTC to act as Depositary with respect to the Book-Entry Notes. 
 Section 2.04 Registrar and Paying Agent.

Section 2.05 Transfer and Exchange. 

The transfer and exchange of Book-Entry Notes or beneficial interests therein shall be effected through the Depositary, in accordance with
Section 3.05 of the Original Indenture and the rules and procedures of the Depositary therefor. 

  
 7 







 Section 2.06 Interest Rates and Payment of Principal and Interest. 

(a) During the Fixed Rate Period, (A) the outstanding principal amount of the Notes and (B) to the extent permitted by applicable
law, any Deferred Interest or overdue interest thereon will bear interest at a per annum rate equal to the Fixed Rate until the commencement of the Floating Rate Period or, if earlier, until the principal thereof and all interest thereon is
paid, compounded semi-annually (in the case of deferred or overdue interest) and payable (subject to the provisions of Article IV) semi-annually in arrears on each Semi-Annual Interest Payment Date. 

(b) During the Floating Rate Period, (A) the outstanding principal amount of the Notes and (B) to the extent permitted by
applicable law, any Deferred Interest or overdue interest thereon will bear interest during each Quarterly Interest Period at a per annum rate equal to the applicable Floating Rate for such period, until the principal thereof and all interest
thereon is paid, compounded quarterly (in the case of deferred or overdue interest) and payable (subject to the provisions of Article IV) quarterly in arrears on each Quarterly Interest Payment Date. The Calculation Agent shall calculate the
Floating Rate with respect to each Floating Rate Period and the amount of interest payable on each Quarterly Interest Payment Date as promptly as practicable according to the appropriate method described herein. Promptly upon such determination, the
Calculation Agent shall notify the Issuer and the Trustee of the Floating Rate for the Quarterly Interest Period and the amount of interest (per $1,000 principal amount of Notes) payable to each Holder on each Quarterly Interest Payment Date.
The Floating Rate determined by the Calculation Agent, absent manifest error, will be binding and conclusive upon the beneficial owners and Holders of the Notes, the Issuer and the Trustee. 

(c) Payments of principal of, and premium, if any, and interest due on, Notes in book-entry form on any Interest Payment Date, upon redemption
or at final maturity will be made available to the Trustee by 11:00 a.m., Eastern time, on the applicable maturity date, Redemption Date or Interest Payment Date, unless such date falls on a day that is not a Business Day, in which case such
payments will be made available to the Trustee by 11:00 a.m., Eastern time, on the next succeeding Business Day; provided, however, that, during the Floating Rate Period, if such next succeeding Business Day falls in the next succeeding calendar
month, then such payments will be made available to the Trustee by 11:00 a.m., Eastern time, on the immediately preceding Business Day. As soon as possible thereafter, the Trustee will make such payments to the Depositary. Other than in connection
with the final maturity or redemption of the Notes or in connection with payment of Defaulted Interest, interest on the Notes may be paid only on an Interest Payment Date. Payments of principal of, and premium, if any, and interest due on, the
Notes other than Book-Entry Notes on any Interest Payment Date, upon redemption or at final maturity will be made in accordance with the provisions of the Original Indenture applicable to such payments with respect to certificated
Securities. Payments of interest due on the Notes shall be payable to the Person in whose name such Note is registered on the Regular Record Date immediately preceding the applicable Interest Payment Date; provided that
interest payable at final maturity or on a Redemption Date shall be paid to the Person to whom principal of the Note is payable. 
 (d) The
amount of interest payable on any Semi-Annual Interest Payment Date during the Fixed Rate Period will be computed on the basis of a 360-day year consisting of
twelve 30-day months. The amount of interest payable on any Quarterly Interest Payment Date during the Floating Rate Period will be computed on the basis of the actual number of days elapsed
during the immediately prior Quarterly Interest Period divided by 360. 
 (e) To the extent permitted by applicable law, interest not paid
when due hereunder, including, without limitation, all Deferred Interest and overdue interest thereon, shall compound until paid, (i) semi-annually in accordance with Section 2.06(a) at the Fixed Rate on each Semi-Annual Interest Payment
Date during the Fixed Rate Period and (ii) quarterly in accordance with Section 2.06(b) at the applicable Floating Rate on each Quarterly Interest Payment Date during the Floating Rate Period. 

  
 8 







 (f) If the Issuer shall make a partial payment of interest on any Interest Payment Date, such
payment shall be applied, first, to Deferred Interest until all such Deferred Interest has been paid and, second, to any Current Interest. 

(g) To the extent that the provisions of this Section 2.06 are inconsistent with the provisions of Article III of the Original Indenture,
the provisions of this Section 2.06 shall control. 
 Article III 

REDEMPTION OF THE NOTES 

Section 3.01 Optional Redemption. 

(a) At any time and from time to time on or after January 22, 2023, the Notes will be subject to redemption at the option of the
Issuer in whole or in part upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest (including any Additional Interest) on
the Notes being redeemed to the Redemption Date. 
 (b) In addition, before January 22, 2023, if a Tax Event shall occur
and be continuing, the Issuer may redeem the Notes following the occurrence of such Tax Event, in whole, but not in part, at a redemption price equal to 100% of the principal amount to be redeemed plus any accrued but unpaid interest
(including any Additional Interest) to the Redemption Date. 
 (c) In addition, before January 22, 2023, if a Rating Agency
Event shall occur and be continuing, the Issuer may redeem the Notes following the occurrence of such Rating Agency Event, in whole, but not in part, at a redemption price equal to 102% of the principal amount to be redeemed plus any accrued
but unpaid interest (including any Additional Interest) to the Redemption Date. 
 (d) In the event of redemption of the Notes in
part only, a new Note or Notes for the unredeemed portion will be issued in the name or names of the Holders thereof upon the surrender thereof. 

(e) Notice of redemption of the Notes pursuant to this Section 3.01 shall be given as provided in Section 11.04 of the

 Article IV 

DEFERRAL OF INTEREST 
 Section 4.01
Optional Deferral. 
 (a) So long as no Event of Default has occurred and is continuing, the Issuer shall have
the right, at any time and from time to time during the term of the Notes, to elect to defer payment of all or any portion of any Current Interest or Deferred Interest otherwise due on the Notes on any Interest Payment Date (an
“Optional Deferral”); provided, however, that the Issuer may not (i) elect to defer payment of any interest otherwise due on any Interest Payment Date if, as a result of such deferral, the Issuer shall have deferred payment of some or
all of the interest due on a number of consecutive Interest 

  
 9 







 
Payment Dates with respect to a number of consecutive Interest Periods which, when taken together as a single period, would exceed ten (10) consecutive years, or (ii) elect to defer
payment of any interest due on the final maturity date of the Notes, or, with respect to any Notes being redeemed, on the Redemption Date for such Notes. During an Optional Deferral Period, no interest on the Notes shall be due
and payable until the end of such Optional Deferral Period (except upon a redemption of the Notes during such period); however, interest shall accrue on the Notes during such period in accordance with Sections 2.06(a), 2.06(b) and
2.06(e). 
 (b) Following the termination of an Optional Deferral Period and the payment of all Deferred Interest accrued during
such Optional Deferral Period, the Issuer may again elect pursuant to Section 4.01(a) to make an Optional Deferral. 
 (c) On the
Interest Payment Date on which the Issuer desires to terminate an Optional Deferral Period or at the end of an Optional Deferral Period pursuant to clause (ii) of the definition of “Optional Deferral Period,” the Issuer shall pay all
Current Interest, Deferred Interest and, to the extent permitted by applicable law, Additional Interest. Such interest shall be payable to the Holders of the Notes in whose names the Notes are registered in the Security Register for the
Notes on the Regular Record Date with respect to such Interest Payment Date. 
 Section 4.02 Notice of Optional Deferrals. 

The Issuer shall give written notice to the Trustee of any election of an Optional Deferral pursuant to Section 4.01 not fewer than
ten (10) nor more than sixty (60) Business Days prior to the earlier of (i) the Interest Payment Date for which the interest on the Notes will be deferred or (ii) the date, if any, upon which the Issuer is required to give notice
of such Interest Payment Date or Regular Record Date therefor to the New York Stock Exchange or any applicable self-regulatory organization. In addition, the Issuer shall deliver to the Trustee an Officers’ Certificate stating that no default
or Event of Default shall have occurred and be continuing. Subject to receipt of such Officers’ Certificate, the Trustee shall forward such notice promptly to the Holders of the Notes. 

Article V 
 CERTAIN
COVENANTS 
 Section 5.01 Certain Covenants in Indenture Inapplicable to the
Notes. 
 Holders of the Notes shall not have the benefit of and shall not be entitled to enforce the covenants contained in
Sections 10.06 and 10.07 of the Original Indenture. Accordingly, for purposes of the Notes only, and not for purposes of any other series of Securities, Article X of the Original Indenture is hereby amended by deleting Sections 10.06 and 10.07
thereof. 
 Section 5.02 Restriction on Certain Payments During Optional Deferral Period. 

(a) Subject to Section 5.02(b), during any Optional Deferral Period, the Issuer shall not (i) declare, pay or make any distributions
with respect to, or redeem, purchase, acquire or make a liquidation payment with respect to, any of its equity securities and (ii) make any payment of interest, principal, or premium, if any, on or repay, repurchase or redeem any debt
securities (including guarantees) issued by the Issuer that rank pari passu with or junior to the Notes. 

  
 10 







 (b) Notwithstanding the provisions of Section 5.02(a), the Issuer may take any of the
following actions at any time, including during an Optional Deferral Period: (i) any of the actions described in Section 5.02(a) resulting from any reclassification of the Issuer’s equity securities or the exchange or conversion of
one class or series of the Issuer’s equity securities for another class or series of the Issuer’s equity securities; (ii) the purchase of fractional interests in the Issuer’s equity securities pursuant to the conversion or
exchange provisions of such equity security or the security being converted or exchanged; (iii) payments or distributions payable in the Issuer’s equity securities; (iv) redemptions, purchases or other acquisitions of the
Issuer’s equity securities in connection with any employment contract, incentive plan, benefit plan or other similar arrangement of the Issuer or any of the Issuer’s subsidiaries or in connection with a dividend or distribution
reinvestment plan; or (v) any declaration of a distribution in connection with implementation of any rights plan, or the issuance of rights, equity securities or other property under any such plan, or the redemption, repurchase or other
acquisition of any such rights pursuant thereto. 
 (c) For the avoidance of doubt, nothing contained herein shall prevent the Issuer from
issuing any other securities, whether senior to, pari passu with or subordinated to the Notes, including securities having covenants and provisions the same as or similar to those applicable to
the Notes, or any guarantees with respect thereto. 
 Article VI 

SUBORDINATION 
 Section 6.01
Subordination. 
 (a) The Notes shall be subordinated to all Senior Indebtedness (as defined in this First Supplemental
Indenture) of the Issuer on the terms and subject to the conditions set forth in Article XIV of the Original Indenture, as amended and supplemented hereby, and each Holder of Notes issued hereunder by such Holder’s acceptance thereof
acknowledges and agrees that all Notes shall be issued subject to the provisions of this Article VI and such Article XIV and that each Holder of Notes, whether upon original issuance or upon transfer or assignment thereof, accepts and
agrees to be bound by such provisions. 
 (b) The Notes shall be subordinated in right of payment to all of the Issuer’s present
and future Senior Indebtedness, and shall rank pari passu in right of payment with Indebtedness Ranking on a Parity with the Notes. 

Section 6.02 Amendment and Restatement of Certain Subordination Provisions. 

(a) For purposes of the Notes only, and not for purposes of any other Securities, Sections 14.02 and 14.03 of the Original Indenture
are hereby amended and restated in their entirety to read as follows: 
 Section 14.02
Liquidation, Dissolution and Bankruptcy. Upon any payment or distribution of the assets of the Partnership to creditors upon a total or partial liquidation
or a total or partial dissolution of the Partnership or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Partnership or its property: 

(a) holders of Senior Indebtedness of the Partnership shall be entitled to receive payment in full in cash of such Senior
Indebtedness (including interest, if any, accruing on or after the commencement of a proceeding in bankruptcy, regardless of whether allowed as a claim against the Partnership in such bankruptcy proceeding) before Holders of Notes shall be
entitled to receive any payment of principal of, or premium, if any, or interest on, the Notes; and 

  
 11 







 (b) until the Senior Indebtedness of the Partnership is paid in full, any such
distribution to which Holders of Notes would be entitled but for this Article XIV shall be made to holders of Senior Indebtedness of the Partnership as their interests may appear, except that such Holders may receive equity securities of
the Partnership and any debt securities of the Partnership that are subordinated to Senior Indebtedness of the Partnership to at least the same extent as the Notes. 

(b) For purposes of the Notes only, and not for purposes of any other Securities, Section 14.03 of the Original Indenture is hereby
amended and restated in its entirety to read as follows: 
 Section 14.03
Default on Senior Indebtedness. The Partnership may not (a) make any payments of the principal of, or premium, if any, or interest on,
the Notes, (b) make any deposit for the purpose of satisfaction and discharge of this Indenture with respect to the Notes or defeasance of the Notes pursuant to Article XIII or (c) purchase, redeem or otherwise retire
any Notes (the foregoing clauses (a), (b) and (c) collectively, “pay the Notes”) if (i) any principal, premium or interest with respect to Senior Indebtedness of the Partnership is not paid within any applicable grace
period (including at final maturity) or (ii) any other default on Senior Indebtedness of the Partnership occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms unless, in either case, (A) the
default has been cured or waived and any such acceleration has been rescinded or (B) such Senior Indebtedness has been paid in full in cash; provided, however, that the Partnership may pay the Notes without regard to the foregoing if
the Partnership and the Trustee receive written notice approving such payment from the Representative of each issue of Designated Senior Indebtedness of the Partnership. During the continuance of any default under any Senior Indebtedness of the
Partnership (other than a default described in the immediately preceding clause (A) or clause (B) of the preceding sentence) that may cause the maturity of any Designated Senior Indebtedness of the Partnership to be accelerated immediately
without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, the Partnership may not pay the Notes for a period (a “Payment Blockage Period”) commencing
upon the receipt by the Partnership and the Trustee (at its Corporate Trust Office) of written notice of such default (a “Blockage Notice”) from the Representative of any Designated Senior Indebtedness of the Partnership, specifying an
election to effect a Payment Blockage Period, and ending 179 days thereafter (or earlier if such Payment Blockage Period is terminated (1) by written notice received by the Partnership and the Trustee (at its Corporate Trust Office) from the
Person or Persons who gave such Blockage Notice, (2) by repayment in full in cash of the Designated Senior Indebtedness with respect to which the Blockage Notice was given or (3) because the default giving rise to such Payment Blockage
Period is no longer continuing). Notwithstanding the provisions described in the immediately preceding sentence (but subject to the provisions contained in the first sentence of this paragraph of this Section 14.03), unless the holders of such
Designated Senior Indebtedness shall have accelerated the maturity of such Designated Senior Indebtedness, the Partnership may pay the Notes after the expiration of such Payment Blockage Period. Not more than one Blockage Notice may be given in
any period of 360 consecutive days, irrespective of the number of defaults with respect to any number of issues of Designated Senior Indebtedness during such period; provided, however, that in no event may the total number of days during which any
Payment Blockage Period or Payment Blockage Periods is in effect exceed 179 days in the aggregate during any period of 360 consecutive days. For purposes of this Section 14.03, no default that existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated Senior Indebtedness of the Partnership 

  
 12 







 
initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the Representative of such Designated Senior Indebtedness,
regardless of whether within a period of 360 consecutive days, unless such default shall have been cured or waived for a period of not less than 90 consecutive days. 

Article VII 

APPLICABILITY OF DEFEASANCE AND COVENANT DEFEASANCE 

Section 7.01 Applicability of Defeasance and Covenant Defeasance 

The Notes will be subject to satisfaction, defeasance and discharge pursuant to Article XIII of the Original Indenture, as amended and
supplemented hereby, in accordance with the provisions of such Article. For the avoidance of doubt, the covenants applicable to the Notes set forth herein, including, but not limited to, pursuant to Section 5.02, may be terminated pursuant
to the covenant defeasance option set forth in Article XIII of the Original Indenture, as amended and supplemented hereby. 
 Article
VIII 
 EVENTS OF DEFAULT AND REMEDIES OF THE TRUSTEE 

AND HOLDERS OF NOTES 
 Section 8.01
Amendment and Restatement of Events of Default Provisions. 
 (a) For purposes of the Notes only, and not for purposes of any
other Securities, Section 5.01 of the Original Indenture is hereby amended and restated in its entirety to read as follows: 

Section 5.01 Events of Default.
“Event of Default,” wherever used herein with respect to the Notes, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 

(a) failure to pay principal of, or premium, if any, or interest on, the Notes when due at final maturity or earlier
redemption; 
 (b) failure to pay interest on the Notes (including Additional Interest) when due and payable (other
than at final maturity or upon earlier redemption) that continues for 30 days (it being understood that the deferral of interest as permitted by Article IV of the First Supplemental Indenture is not a default in payment of interest on
the Notes); or 
 (c) the occurrence of a Bankruptcy Event with respect to the Issuer. 

(b) For purposes of the Notes only, and not for purposes of any other Securities, Section 5.02 of the Original Indenture is hereby
amended and restated in its entirety to read as follows: 
 Section 5.02 Acceleration of
Maturity; Rescission and Annulment. If an Event of Default with respect to the Notes occurs and is continuing, then, and in each and every case that an Event of Default described in clause (a) or clause (b) with respect to
the Notes at the time Outstanding occurs and is continuing, unless the principal of, premium, if any, and accrued and unpaid interest on all the Notes shall have already become due and payable, either the Trustee or


  
 13 







 
the Holders of not less than 25% in aggregate principal amount of the Notes then Outstanding hereunder, by notice in writing to the Partnership (and to the Trustee if given by Holders), may,
and the Trustee at the request of such Holders shall, declare the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately
due and payable, anything in the Notes, this Indenture or in the First Supplemental Indenture contained to the contrary notwithstanding. If an Event of Default described in clause (c) occurs, then and in each and every such case, unless the
principal of and accrued and unpaid interest on all the Notes shall have become due and payable, the principal of, and accrued and unpaid interest on, all the Notes then Outstanding hereunder shall ipso facto become and be immediately due
and payable without any declaration or other act on the part of the Trustee or any Holders, anything in the Notes, this Indenture or in the First Supplemental Indenture contained to the contrary notwithstanding. 

The Holders of a majority in aggregate principal amount of the Notes then Outstanding by written notice to the Trustee may
rescind an acceleration and annul its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction already rendered and if all existing Events of Default with respect to the Notes have been
cured or waived except nonpayment of principal, premium, if any, or accrued and unpaid interest that has become due solely because of acceleration. Upon any such rescission, the parties hereto shall be restored respectively to their several
positions and rights hereunder, and all rights, remedies, and powers of the parties hereto shall continue as though no such proceeding had been taken. 

With respect to the Notes, the term “Default” shall mean the following event: default in the performance or
breach of any covenant or warranty of the Partnership in this Indenture (other than (i) a covenant or warranty a default in the performance of which or the breach of which is addressed in Section 5.01 or (ii) any other covenants and
warranties inapplicable to the Notes), and continuance of such default or breach for a period of 90 days after specified written notice to the Partnership by the Trustee, or to the Partnership and the Trustee by the holders of at least 25% in
principal amount of the Outstanding Notes. 
 Upon the occurrence and continuance of a Default, the Trustee and the holders
of the Notes shall have the same rights and remedies, and shall be subject to the same limitations, restrictions, protections and exculpations, and the Partnership will be subject to the same obligations and restrictions, in each case, as would
apply if such Default were an Event of Default or an event that after notice or lapse of time or both would become an Event of Default; provided that the principal of and accrued and unpaid interest on the Notes may not be declared immediately
due and payable by reason of the occurrence and continuation of a Default, and any notice of declaration or acceleration based on such Default shall be null and void with respect to the Notes; provided, further that in case a Default has
occurred and is continuing, the Trustee shall not be subject to the requirement to exercise, with respect to the Notes, the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs, unless an
Event of Default has occurred and is continuing. 
 The Trustee shall not be deemed to have notice of any Default or Event of
Default, except an Event of Default under Section 5.01(a) or Section 5.01(b), unless a Trust Officer has received written notice of such Default or Event of Default at the Corporate Trust Office.

 Article IX 

MISCELLANEOUS PROVISIONS 

Section 9.01 Ratification of Original Indenture and First Supplemental Indenture. 

The Original Indenture, as amended and supplemented by this First Supplemental Indenture, is in all respects ratified and confirmed, and this
First Supplemental Indenture shall be deemed part of the Original Indenture, in the manner and to the extent herein and therein provided; provided, however, that the provisions of this First Supplemental Indenture apply solely with respect to the
Notes. The Indenture shall, solely in respect of the Notes, be deemed a “junior subordinated indenture.” 
 Section 9.02 Non- Recourse to General Partner. 

Obligations of the Issuer under this First Supplemental Indenture, the Original Indenture and the Notes are
non-recourse to the General Partner, and its respective Affiliates (other than the Issuer), and payable only out of cash flow and assets of the Issuer. The Trustee, and each Holder of a Note by its acceptance
thereof, will be deemed to have agreed in the Indenture that (1) neither the General Partner nor its assets (nor any of its Affiliates, other than the Issuer, or their respective assets) shall be liable for any of the obligations of the Issuer
under the Indenture or the Notes, and (2) no director, officer, employee, stockholder, member or unitholder, as such, of the Issuer, the Trustee, the General Partner or any Affiliate of any of the foregoing entities shall have any personal
liability in respect of the obligations of the Issuer under the Indenture or the Notes by reason of his, her or its status. Each Holder of Notes by accepting a Note waives and releases the General Partner and its directors, officers, employees and
sole member from all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 
 Section 9.03
Treatment of the Notes. 
 By its acceptance of the Notes or a beneficial
interest therein, each Holder and beneficial owner of such Notes shall be deemed to have agreed to treat such Notes as indebtedness for all United States federal, state and local tax purposes.

reference only, are not to be considered a part hereof and shall in no way modify or restrict any of the terms or provisions hereof. 
 Section 9.05
Separability. 
 In case any one or more of the provisions contained in this First Supplemental Indenture or in the Notes shall
for any reason be held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions of this First Supplemental Indenture or of such Notes, but this First Supplemental
Indenture and such Notes shall be construed as if such invalid or illegal or unenforceable provision had never been contained herein or therein. 

Section 9.06 Counterpart Originals. 

The parties may sign any number of copies of this First Supplemental Indenture. Each signed copy shall be an original, but all of them together
represent the same agreement. The exchange of signed copies of this First Supplemental Indenture by facsimile transmission or emailed portable document format (pdf) shall constitute effective execution and delivery of this First Supplemental
Indenture as to 

  
 15 







 
the parties hereto and such copies may be used in lieu of the original First Supplemental Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or portable
document format (pdf) shall be deemed to be their original signatures for all purposes other than authentication of Notes by the Trustee. 

Section 9.07 Governing Law. 

THIS FIRST SUPPLEMENTAL INDENTURE AND THE NOTES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

 Section 9.08 Certain Trustee Matters. 

The recitals contained herein shall be taken as the statements of the Issuer, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this First Supplemental Indenture or the Notes or the proper authorization or the due execution hereof or thereof by the Issuer.

 [REVERSE OF SECURITY] 

BUCKEYE PARTNERS, L.P. 

JUNIOR SUBORDINATED NOTES DUE 2078 

The Notes are one of a duly authorized issue of Securities of the Issuer issued under and pursuant to the Indenture, to which Indenture
reference is hereby made for a description of the rights, limitations of rights, obligations, duties, and immunities thereunder of the Trustee, the Issuer and the Holders of the Securities. The Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as
provided in the Indenture. The Notes are of a series designated as the Junior Subordinated Notes due 2078 of the Issuer (the “Notes”). 
  

	1.	Interest. 

 During the Fixed Rate Period, the outstanding principal amount hereof and (to the
extent that payment of such interest is enforceable under applicable law) any Deferred Interest or overdue installment of interest hereon will bear interest at the per annum rate of 6.375%, payable (subject to the provisions of the Indenture
relating to interest deferrals more fully described below) semi-annually in arrears on January 22 and July 22 of each year, commencing July 22, 2018 through the end of the Fixed Rate Period, compounded semi-annually at such per annum
rate (in the case of any deferred or overdue interest). If an Interest Payment Date occurs during the Fixed Rate Period on a day that is not a Business Day, then payment of the interest payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of any such delay), with the same force and effect as if made on the date the payment was originally payable. 

During the Floating Rate Period, the outstanding principal amount hereof and (to the extent that payment of such interest is enforceable under
applicable law) any Deferred Interest or overdue installment of interest hereon will bear interest during each Quarterly Interest Period at the applicable Floating Rate for such Quarterly Interest Period calculated pursuant to the Indenture,
payable (subject to the provisions of the Indenture relating to interest deferrals more fully described below) quarterly in arrears on each Quarterly Interest Payment Date (as defined below) through the end of the Floating Rate Period, compounded
quarterly at such prevailing Floating Rate (in the case of any deferred or overdue interest). “Quarterly Interest Payment Date” means each January 22, April 22, July 22 and October 22 during the Floating Rate
Period, commencing April 22, 2023; provided, however, that if any such day (other than on January 22, 2078 or an earlier Redemption Date) is not Business Day, then the Quarterly Interest Payment Date shall be the next day that is a
Business Day, except that if such next day that is a Business Day falls in the next succeeding calendar month, then such payment shall be made on the immediately preceding Business Day. 

During the Fixed Rate Period, the amount of interest payable on any Semi-Annual Interest Payment Date will be computed on the basis of a 360-day year of twelve 30-day months. During the Floating Rate Period, the amount of interest payable on any Quarterly Interest Payment Date will be
computed on the basis of the actual number of days elapsed during the immediately prior Quarterly Interest Period divided by 360. 

  
 A-4 








	2.	Optional Deferral of Interest. 

 Subject to the terms of the Indenture, the Issuer shall have
the right, at any time and from time to time during the term of the Notes, to elect to defer payment of all or any portion of any Current Interest or Deferred Interest otherwise due on the Notes on any Interest Payment Date as set forth in
Article IV of the First Supplemental Indenture (as defined below). No interest on the Notes shall be due and payable on any Interest Payment Date during an Optional Deferral Period; however, interest shall accrue on the Notes during such period in
accordance with the Indenture. 
  

	3.	Method of Payment. 

 The Issuer shall pay interest on the Notes (except Defaulted Interest)
to the Persons who are the registered Holders at the close of business on the Regular Record Date immediately preceding the applicable Interest Payment Date. The Issuer shall pay principal, premium, if any, and interest in such coin or currency of
the United States of America as at the time of payment shall be legal tender for payment of public and private debts. Payments in respect of a Global Security (including principal, premium, if any, and interest) will be made by wire transfer of
immediately available funds to the accounts specified by the Depositary. Payments in respect of Notes in definitive form (including principal, premium, if any, and interest) will be made at the office or agency of the Issuer maintained for such
purpose within the contiguous United States, which initially will be the Corporate Trust Office, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders on the relevant Regular Record Date at their addresses
set forth in the Security Register of Holders or at the option of the Holder, payment of interest on Notes in definitive form will be made by wire transfer of immediately available funds to any account maintained in the United States, provided such
Holder has requested such method of payment and provided timely wire transfer instructions to the paying agent. The Holder must surrender this Note to a paying agent to collect payment of principal. 

 

	4.	Paying Agent and Registrar. 

 Initially, Branch Banking and Trust Company will act as paying
agent and Registrar. The Issuer may change any paying agent or Registrar at any time upon notice to the Trustee and the Holders. The Issuer may act as paying agent. 
  

	5.	Indenture. 

 The Notes are one of a duly authorized issue of Securities of the Issuer issued, or
to be issued, under the Indenture, dated as of January 22, 2018 (the “Original Indenture”) between Buckeye Partners, L.P., as issuer, and Branch Banking and Trust Company, as trustee (the “Trustee”), as amended and
supplemented by the First Supplemental Indenture thereto dated as of January 22, 2018 (the “First Supplemental Indenture”), between the Issuer and the Trustee, providing for the issuance of Securities of the series whose
designation appears on the face hereof. The Original Indenture, as amended and supplemented by the First Supplemental Indenture, and as may be further duly amended and supplemented in accordance with the terms thereof in relation to the Notes, is
referred to herein as the “Indenture.” Capitalized terms used but not defined herein shall have the respective meanings given to such terms in the Indenture. 

The terms of the Notes include those stated in the Indenture, those made part of the Indenture by reference to the TIA, as in effect on
the date of the First Supplemental Indenture, and those terms stated in the First Supplemental Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of them. The Notes are junior
subordinated obligations of the Issuer and are not secured by any of the assets of the Issuer. 

  
 A-5 








	6.	Denominations; Transfer; Exchange. 

 The Notes are to be issued in registered form, without
coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange, Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. 
  

	7.	Person Deemed Owners. 

 The registered Holder of Notes may be treated as the owner of it for all
purposes. 
  

	8.	Amendment; Supplement; Waiver. 

 Subject to certain exceptions, the Indenture may be amended or
supplemented, and any existing Event of Default or compliance with any provision may be waived, with the consent of the Holders of a majority in principal amount of the Outstanding Securities of each series affected. Without consent of any Holder of
Notes, the parties thereto may amend or supplement the Indenture to, among other things, cure any ambiguity or correct any inconsistency. Any such consent or waiver by the Holder of this Note (unless revoked as provided in the Indenture) shall
be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and any Notes that may be issued in exchange or substitution herefor, irrespective of whether any notation thereof is made upon this Note or such
other Notes. 
  

	9.	Defaults and Remedies. 

 Certain events of bankruptcy, insolvency or reorganization involving
the Issuer are Events of Default that will result in the principal amount of the Notes, together with accrued and unpaid interest thereon, becoming due and payable immediately upon the occurrence of such Events of Default. If any other Event of
Default with respect to the Notes occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then Outstanding may declare the principal amount of all the Notes,
together with accrued and unpaid interest thereon, to be due and payable immediately in the manner and with the effect provided in the Indenture. Notwithstanding the preceding sentence, however, at any time after such a declaration of acceleration
has been made, the Holders of a majority in principal amount of the Outstanding Notes, by written notice to the Trustee, may rescind such declaration and annul its consequences if the rescission would not conflict with any judgment or decree of
a court already rendered and if all Events of Default with respect to the Notes, other than the nonpayment of the principal, premium, if any, or accrued and unpaid interest that has become due solely by such declaration of acceleration, shall have
been cured or shall have been waived. No such rescission shall affect any subsequent default or shall impair any right consequent thereon. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee
may require indemnity or security satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Notes then Outstanding may direct the Trustee in its
exercise of any trust or power with respect to the Notes. 
 Upon the occurrence and continuance of a Default, the Trustee and the holders
of the Notes shall have the same rights and remedies, and shall be subject to the same limitations, restrictions, protections and exculpations, and the Issuer will be subject to the same obligations and restrictions, in each case, as would apply if
such Default were an Event of Default or an event that after notice or lapse of time or both would become an Event of Default; provided that the principal of and accrued and unpaid interest on the Notes may not be declared immediately due and
payable by reason of the occurrence and continuation of a Default, and any notice of declaration or acceleration based on such Default shall be null and void with 

  
 A-6 







 
respect to the Notes; provided, further that in case a Default has occurred and is continuing, the Trustee shall not be subject to the requirement to exercise, with respect to the Notes, the same
degree of care as a prudent individual would exercise in the conduct of his or her own affairs, unless an Event of Default has occurred and is continuing. 
  

	10.	Trustee Dealings with Issuer. 

 The Trustee under the Indenture, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for the Issuer or its Affiliates or any subsidiary of the Issuer’s Affiliates, and may otherwise deal with the Issuer or its Affiliates as if it were not the Trustee. 

 

	11.	Authentication. 

 This Note shall not be valid until the Trustee signs the certificate of
authentication on the other side of this Note. 
  

	12.	Abbreviations and Defined Terms. 

 Customary abbreviations may be used in the name of a Holder
of a Note or an assignee, such as: TEN COM (tenant in common), TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A (Uniform Gifts to Minors Act). 

 

	13.	CUSIP Numbers. 

 Pursuant to a recommendation promulgated by the Committee on Uniform Note
Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of such number as printed on the Notes and reliance may be placed
only on the other identification numbers printed hereon. 
  

	14.	Absolute Obligation. 

 No reference herein to the Indenture and no provision of the Notes or the
Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on the Notes in the manner, at the respective times, at the rate and in the coin or
currency therein and herein prescribed. 
  

	15.	No Recourse. 

 Obligations of the Issuer under the Notes, the First Supplemental Indenture and
the Original Indenture are non-recourse to the General Partner, and its respective Affiliates (other than the Issuer), and payable only out of cash flow and assets of the Issuer. The Trustee, and each Holder
of a Note by its acceptance thereof, will be deemed to have agreed in the Indenture that (1) neither the General Partner nor its assets (nor any of its Affiliates, other than the Issuer, or their respective assets) shall be liable for any of
the obligations of the Issuer under the Indenture or the Notes, and (2) no director, officer, employee, stockholder or unitholder, as such, of the Issuer, the Trustee, the General Partner or any Affiliate of any of the foregoing entities shall
have any personal liability in respect of the obligations of the Issuer under the Notes or the Indenture by reason of his, her or its status.

	16.	Ranking. 

 The Notes rank junior and subordinate in rank and priority of payment to all of the
Issuer’s Senior Indebtedness as more fully provided in Article XIV of the Indenture and Article VI of the First Supplemental Indenture. 
  

	17.	Optional Redemption. 

 The Notes are subject to redemption prior to final maturity at the
redemption prices and in the manner provided in the First Supplemental Indenture. 
  

	18.	Governing Law. 

 The Notes shall be construed in accordance with and governed by the laws of the
State of New York.
