Item 1.01 Entry into a Material Definitive Agreement.

On September 14, 2026, Plains All American

Pipeline, L.P. (“PAA” or the “Issuer”) completed the public offering (the “Offering”) of $700,000,000

aggregate principal amount of 6.750% Series A Junior Subordinated Notes due 2056 (the “Series A Notes”) and $800,000,000

aggregate principal amount of 7.000% Series B Junior Subordinated Notes due 2056 (the “Series B Notes,” and, together

with the Series A Notes, the “Notes”).

The terms of the Notes are governed by the Subordinated

Indenture (the “Subordinated Indenture,” and as amended and supplemented

by the Supplemental Indentures (defined below), the “Indenture”) dated as of September 14, 2026 by and between the Issuer

and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture,

dated as of September 14, 2026, by and between the Issuer and the Trustee (the “1st Supplemental Indenture”) relating

to the issuance of the Series A Notes and the Second Supplemental Indenture, dated as of September 14, 2026, by and between

the Issuer and the Trustee (the “2nd Supplemental Indenture,” and, together with the 1st Supplemental Indenture, the “Supplemental

Indentures”) relating to the issuance of the Series B Notes.

The Notes

will mature on December 15, 2056. Interest is payable on the Notes on each of June 15 and December 15, commencing on June 15,

2027.

The interest

rates on the Series A Notes and the Series B Notes will be subject to adjustment on December 15, 2031 and December 15,

2036, respectively (the “First Reset Date”), and on each five-year anniversary thereafter. The adjusted interest rates will

be based on the then applicable Five-Year U. S. Treasury Rate plus a spread; provided that the interest rate during such periods will

not reset below the initial interest rate of the applicable series of Notes. In addition, the Series A Notes and the Series B

Notes will be subject to redemption by PAA during the 90-day period prior to the applicable First Reset Date and thereafter on any applicable

interest payment date. Further, the Issuer may redeem some or all of the Notes at such other times and subject to such other restrictions

specified in the Indenture.

The Notes

are PAA’s unsecured obligations, and will rank junior and subordinate in right of payment to the prior payment of PAA’s existing

and future senior indebtedness. The Notes will rank equally in right of payment with any future unsecured indebtedness that PAA may incur

from time to time if the terms of such indebtedness provide that it ranks equally with the Notes in right of payment. None of PAA’s subsidiaries

will guarantee the Notes.

Other

material terms of the Notes, the Subordinated Indenture and the Supplemental Indentures are described in the prospectus supplement, dated

September 9, 2026 (the “prospectus supplement”), to the prospectus, dated September 6, 2024, which is included in

by reference to such Indenture (including the forms of Notes attached thereto). Copies of the Subordinated Indenture, 1st Supplemental

Indenture and the 2nd Supplemental Indenture are filed as Exhibit 4.1, Exhibit 4.2 and Exhibit 4.4, respectively, to this

necessary, except where the failure so to register or qualify would not (i) reasonably be expected to have a material adverse effect

upon the condition (financial or other), business, prospects, properties, net worth or results of operations of the Partnership’s

direct and indirect majority owned subsidiaries (collectively, the “Subsidiaries”) and the Partnership (collectively,

the “Plains Entities”), taken as a whole (a “Material Adverse Effect”), or (ii) subject

an “Organizational Document”) of the Partnership and the GP Entities, and such membership interests and limited

partner interests are fully paid (to the extent required under their applicable Organizational Documents) and nonassessable (except (A) in

the case of a limited partnership or Delaware limited liability company, as such nonassessability may be affected by Sections 17-303,

18-607 and 18-804 of the Delaware Limited Liability Company Act (the “Delaware LLC Act”), as applicable, or

(B) with respect to the general partner interest of any such entity); and such general partner, limited partner and membership interests

held by the GP Entities are owned by the applicable GP Entity free and clear of all liens, encumbrances, security interests, equities,

charges or claims (“Liens”), except (i) as disclosed in the Registration Statement, the Pricing Disclosure

and validly issued (in accordance with the Organizational Documents of such Material Subsidiary), are fully paid (in the case of an interest

in a limited partnership or limited liability company, to the extent required under the Organizational Documents of such Material Subsidiary)

and nonassessable (except (A) in the case of an interest in a Delaware limited partnership or Delaware limited liability company,

as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act or Sections 18-607 and 18-804 of

effective before the offering of the Notes may commence, the Issuer will endeavor to cause such post-effective amendment to become effective

as soon as possible and will advise the Representatives promptly and, if requested by the Representatives, will confirm such advice in

writing when such post-effective amendment has become effective.

(b)             Preparation

of Prospectus and Registration Statement. The Issuer will advise the Representatives promptly and, if requested by the Representatives,

will confirm such advice in writing: (i) of any request by the Commission for amendment of or a supplement to the Registration Statement,

the Preliminary Prospectus or the Prospectus or for additional information; (ii) of the issuance by the Commission of any stop order

suspending the effectiveness of the Registration Statement or of the suspension of qualification of the Notes for offering or sale in

any jurisdiction or the initiation of any proceeding for such purpose; and (iii) within the period of time referred to in paragraph (e) below,

of any change in the condition (financial or other), business, prospects, properties, net worth or results of operations of the Plains

Entities, taken as a whole, or of the happening of any event that makes any statement of a material fact made in the Registration Statement,

the Pricing Disclosure Package or the Prospectus (as then amended or supplemented) untrue or that requires the making of any additions

to or changes in the Registration Statement, the Pricing Disclosure Package or the Prospectus (as then amended or supplemented) in order

to state a material fact required by the Securities Act or the regulations thereunder to be stated therein or necessary in order to make

the statements therein (in the case of any Preliminary Prospectus or the Prospectus, in the light of the circumstances under which any

such statements were made) not misleading, or of the necessity to amend or supplement the Prospectus (as then amended or supplemented)

to comply with the Securities Act or any other applicable law. If at any time the Commission shall issue any stop order suspending the

effectiveness of the Registration Statement, the Partnership will make every commercially reasonable effort to obtain the withdrawal

of such order at the earliest possible time.

Term Sheet and Issuer Free Writing Prospectuses. The Issuer agrees (i) to prepare a final term sheet, containing a description

of the final terms of the Notes and the offering thereof, in the form approved by the Representatives and attached as Schedule II

hereto, and to file such term sheet pursuant to Rule 433 of the Rules and Regulations within the time required by such Rule and

(ii) not to make any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus without the prior written

consent of the Representatives.

(d)             Copies

of Registration Statement. The Issuer will furnish to the Underwriters, without charge, such number of copies of (i) the

manually signed copy of the registration statement corresponding to the Commission’s electronic data gathering, analysis and retrieval

system (“EDGAR”) version filed with the Commission and of each amendment thereto, including financial statements

and all exhibits to the registration statement, (ii) the registration statement as originally filed and of each amendment thereto,

without exhibits, (iii) the Incorporated Documents, without exhibits, and (iv) the exhibits to the Incorporated Documents,

in each case, as the Underwriters may reasonably request.

(e)             Filing

of Amendment or Supplement. For such period as in the opinion of counsel for the Underwriters a prospectus is required by the

Securities Act to be delivered in connection with sales by any Underwriter or any dealer, the Issuer will not file any amendment to the

Registration Statement, supplement to the Prospectus (or any other prospectus relating to the Notes filed pursuant to Rule 424(b) of

the Rules and Regulations that differs from the Prospectus as filed pursuant to such Rule 424(b)), or any Preliminary Prospectus

or Issuer Free Writing Prospectus of which the Representatives shall not previously have been advised or to which the Representatives

shall have reasonably objected in writing after being so advised unless the Issuer shall have determined based upon the advice of counsel

that such amendment, supplement or other filing is required by law; and the Issuer will promptly notify the Representatives after they

shall have received notice thereof of the time when any amendment to the Registration Statement becomes effective or when any supplement

to the Prospectus has been filed.

(f)             Copies

of Documents to the Underwriters. As soon after the Applicable Time as possible and thereafter from time to time for such period

as in the opinion of counsel for the Underwriters a prospectus is required by the Securities Act to be delivered in connection with sales

by any Underwriter or any dealer, the Issuer will expeditiously deliver to each Underwriter and each dealer that the Underwriters may

specify, without charge, as many copies of the Prospectus (and of any amendment or supplement thereto) as the Underwriters may reasonably

request. At any time after nine months after the time of issuance of the Prospectus, upon request and without charge, the Issuer will

deliver as many copies of an amended or supplemented Prospectus complying with Section 10(a)(3) of the Securities Act as the

Underwriters may reasonably request, provided that a prospectus is required by the Securities Act to be delivered in connection

with sales of the Notes by any Underwriter or any dealer. The Issuer consents to the use of the Prospectus (and of any amendment or supplement

thereto) in accordance with the provisions of the Securities Act and with the securities or Blue Sky laws of the jurisdictions in which

the Notes are offered by the Underwriters and by all dealers to whom Notes may be sold, both in connection with the offering and sale

of the Notes and for such period of time thereafter as the Prospectus is required by the Securities Act to be delivered in connection

with sales by any Underwriter or any dealer. If during such period of time any event shall occur that in the judgment of the Issuer or

in the opinion of counsel for the Underwriters and the Issuer is required to be set forth in the Prospectus (as then amended or supplemented)

or should be set forth therein in order to make the statements therein, in the light of the circumstances under which they were made,

not misleading, or if it is necessary to supplement or amend the Prospectus (or to file under the Exchange Act any document which, upon

filing, becomes an Incorporated Document) to comply with the Securities Act or any other law, the Issuer will forthwith prepare and,

subject to the provisions of paragraph (e) above, file with the Commission an appropriate supplement or amendment thereto

(or to such document), and will expeditiously furnish to the Underwriters and dealers a reasonable number of copies thereof; provided

that, if any such event necessitating a supplement or amendment to the Prospectus occurs at any time after nine months after the time

of issuance of the Prospectus, such supplement or amendment shall be prepared at the Underwriters’ expense. In the event that the

Issuer and the Representatives agree that the Prospectus should be amended or supplemented, the Issuer, if requested by the Representatives,

will promptly issue a press release announcing or disclosing the matters to be covered by the proposed amendment or supplement unless

the Issuer shall have determined, based on the advice of counsel, that the issuance of such press release would not be required by law.

(g)             Blue

Sky Laws. The Issuer will cooperate with the Representatives and with counsel for the Underwriters in connection with the registration

or qualification of the Notes for offering and sale by the Underwriters and by dealers under the securities or Blue Sky laws of such

jurisdictions as the Underwriters may reasonably designate and will file such consents to service of process or other documents reasonably

necessary or appropriate in order to effect such registration or qualification; provided that in no event shall any Plains Entity

be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject

it to service of process in suits, other than those arising out of the offering or sale of the Notes, in any jurisdiction where it is

not now so subject. The Issuer will promptly notify the Representatives of the receipt by the Issuer of any notification with respect

to the suspension of the qualification of the Notes for sale in any jurisdiction or the initiation or threatening of any proceeding for

such purpose.

(h)             Reports

to Security Holders. In accordance with Section 11(a) of the Securities Act and Rule 158 of the Rules and

Regulations, the Issuer will make generally available to their security holders an earnings statement (which need not be audited) in

reasonable detail covering the 12-month period beginning not later than the first day of the month next succeeding the month in which

occurred the effective date (within the meaning of such Rule 158) of the Registration Statement as soon as practicable after the

end of such period.

(i)             Copies

of Reports. Unless otherwise available on EDGAR, during the period of two years hereafter, the Issuer will furnish or make available

to the Underwriters (i) as soon as publicly available, a copy of each report of the Issuer mailed to unitholders or filed with the

Commission or the principal national securities exchange or automated quotation system upon which the Notes may be listed, and (ii) from

time to time such other information concerning the Issuer as the Underwriters may reasonably request.

(j)             Termination

Expenses. If this Agreement shall terminate or shall be terminated after execution pursuant to any provisions hereof (other than

pursuant to Section 9 hereof or Section 10 hereof (except pursuant to the first clause of Section 10(i)))

or if this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of the Issuer to comply with

the terms or fulfill any of the conditions of this Agreement, the Issuer agrees to reimburse the Underwriters for all reasonable and

documented out-of-pocket expenses (including reasonable and documented fees and expenses of counsel for the Underwriters) incurred by

the Underwriters in connection herewith.

(k)             Application

of Proceeds. The Issuer will apply the net proceeds from the sale of the Notes in accordance with the description set forth under

the caption “Use of Proceeds” in the Pricing Disclosure Package and the Prospectus.

(l)             Filing

of Prospectus. The Issuer will timely file the Prospectus, and any amendment or supplement thereto, pursuant to Rule 424(b) of

the Rules and Regulations and will advise the Underwriters of the time and manner of such filing.

(m)             Stabilization.

Except as stated in this Agreement and the Prospectus, the Issuer has not taken, nor will take, directly or indirectly, any action designed

to or that might reasonably be expected to cause or result in stabilization or manipulation of the price of any security of the Issuer

to facilitate the sale or resale of the Notes.

(n)             Investment

Company. The Issuer will take such steps as shall be necessary to ensure that none of the Plains Entities or the GP Entities

shall become an “investment company” within the meaning of such term under the Investment Company Act and the rules and

regulations of the Commission thereunder.

(o)             Exchange

Act Reports. The Issuer, during the period when the Prospectus is required to be delivered under the Securities Act, will file

all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange

Act.

(p)             Free

Writing Prospectuses. The Issuer has complied and will comply with the requirements of Rule 433 of the Rules and Regulations

applicable to any Issuer Free Writing Prospectus, including appropriate legending and timely filing with the Commission or retention

where required. The Issuer agrees that they will satisfy the conditions under Rule 433 of the Rules and Regulations to avoid

a requirement to file with the Commission any electronic road show. The Issuer agrees that if at any time following issuance of an Issuer

Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the

information in the Registration Statement, the most recent Preliminary Prospectus or the Prospectus or would include an untrue statement

of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances

then prevailing, not misleading, the Issuer will give prompt notice thereof to the Representatives and, if requested by the Representatives,

will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document that will correct such

conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements

or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the

Issuer by an Underwriter through the Representatives expressly for use therein, which information is specified in Section 12.

(q)             Clear

Market. During the period from the date hereof through and including the business day following the Delivery Date, the Issuer

will not, without the prior written consent of the Representatives, offer, sell, contract to sell or otherwise dispose of any debt securities

issued or guaranteed by the Issuer and having a tenor of more than one year.

6.             Indemnification

and Contribution.

(a)             The

Issuer agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter, each

affiliate of any Underwriter who has participated in the distribution of the Notes as an underwriter, each broker-dealer affiliate of

any Underwriter, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or

Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and expenses, joint or several

(including reasonable and documented costs of investigation), to which they or any of them became subject under the Securities Act, the

Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses arise out of, or are based upon, (i) any

untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus,

the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any “road show” (as defined

in Rule 433 of the Rules and Regulations) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus

Road Show”) or (ii) the omission or alleged omission to state in the Registration Statement, any Preliminary Prospectus,

the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show, any

material fact required to be stated therein or necessary to make the statements therein (in the case of any Preliminary Prospectus or

the Prospectus, in the light of the circumstances under which any such statements were made) not misleading, and shall reimburse each

Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other documented expenses

reasonably incurred by that Underwriter, director, officer, employee or controlling person in connection with investigating or defending

or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however,

that the Issuer shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out

of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement,

any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any

Non-Prospectus Road Show, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Issuer

through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely

of the information specified in Section 12. The foregoing indemnity agreement is in addition to any liability that the Issuer

may otherwise have to any Underwriter or to any director, officer, employee or controlling person of that Underwriter.

(b)             If

any action, suit or proceeding shall be brought against any Underwriter, any director, officer, employee or agent of any Underwriter

or any person controlling any Underwriter in respect of which indemnity may be sought against an Issuer, such Underwriter or such director,

officer, employee, agent or controlling person shall promptly notify the Partnership in writing, and the Issuer shall assume the defense

thereof, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all reasonable and documented

fees and expenses. The failure to notify the indemnifying party shall not relieve it from liability that it may have to an indemnified

party unless the indemnifying party is foreclosed by reason of such delay from asserting a defense otherwise available to it. Such Underwriter

or any such director, officer, employee, agent or controlling person shall have the right to employ separate counsel in any such action,

suit or proceeding and to participate in (but not control) the defense thereof, but the fees and expenses of such counsel shall be at

the expense of such Underwriter or such director, officer, employee, agent or controlling person unless (i) the Issuer has agreed

in writing to pay such fees and expenses, (ii) the Issuer has failed to assume the defense and employ counsel within a reasonable

period of time in light of the circumstances or (iii) such indemnified party or parties shall have reasonably concluded, based on

the advice of counsel, that there may be defenses available to it or them that are different from, additional to or in conflict with

those available to the Issuer (in which case the Issuer shall not have the right to direct the defense of such action, suit or proceeding

on behalf of the indemnified party or parties), in any of which events the Issuer shall pay the reasonable and documented fees and expenses

of such counsel as such fees and expenses are incurred (it being understood, however, that the Issuer shall not be liable for the expenses

of more than one separate counsel (in addition to any local counsel) in any one action, suit or proceeding or series of related actions,

suits or proceedings in the same jurisdiction representing the indemnified parties who are parties to such action, suit or proceeding).

Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Issuer, GP LLC’s directors and the officers who

signed the Registration Statement, and any person who controls the Issuer within the meaning of Section 15 of the Securities Act

or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Issuer to each Underwriter, but only with

respect to information furnished in writing by or on behalf of such Underwriter through the Representatives expressly for use in the

Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement

thereto or in any Non-Prospectus Road Show, which information is limited to the information set forth in Section 12. If any

action, suit or proceeding shall be brought against an Issuer, any of such directors and officers or any such controlling person based

on the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or

supplement thereto or in any Non-Prospectus Road Show, and in respect of which indemnity may be sought against any Underwriter pursuant

to this paragraph (c), such Underwriter shall have the rights and duties given to the Issuer by paragraph (b) above

(except that if the Issuer shall have assumed the defense thereof such Underwriter shall not be required to do so, but may employ separate

counsel therein and participate in (but not control) the defense thereof, but the fees and expenses of such counsel shall be at such

Underwriter’s expense), and the Issuer, any of such directors and officers and any such controlling person shall have the rights

and duties given to the Underwriters by paragraph (b) above. The foregoing indemnity agreement shall be in addition

to any liability that the Underwriters may otherwise have.

(d)             If

the indemnification provided for in this Section 6 is unavailable to an indemnified party under paragraph (a) or

(c) hereof in respect of any losses, claims, damages, liabilities or expenses referred to therein, then an indemnifying party,

in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result

of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits

received by the Issuer on the one hand and the Underwriters on the other hand from the offering of the Notes, or (ii) if the allocation

provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not

only the relative benefits referred to in clause (i) above but also the relative fault of the Issuer on the one hand

and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities

or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Issuer on the one hand and

the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting

expenses) received by the Issuer bear to the total underwriting discounts and commissions received by the Underwriters, in each case

as set forth in the table on the cover page of the Prospectus. The relative fault of the Issuer on the one hand and the Underwriters

on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material

fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuer or any affiliate of the

Issuer on the one hand, or by the Underwriters on the other hand, and the parties’ relative intent, knowledge, access to information

and opportunity to correct or prevent such statement or omission.

(e)             The

Issuer and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 6 were

determined by a pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of

allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount

paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities and expenses referred to in paragraph (d) above

shall be deemed to include, subject to the limitations set forth above, any legal or other documented expenses reasonably incurred by

such indemnified party in connection with investigating any claim or defending any such action, suit or proceeding. Notwithstanding the

provisions of this Section 6, no Underwriter shall be required to contribute any amount in excess of the amount by which

the total price of the Notes underwritten by it and distributed to the public exceeds the amount of any damages that such Underwriter

has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty

of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution

from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided

in this Section 6 are several and not joint.

(f)             No

indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably

withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit

or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are

actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release

of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings

of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action

effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying

party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless

any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(g)             Any

losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under

this Section 6 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities

or expenses are incurred. The indemnity and contribution agreements contained in this Section 6 and the covenants, representations

and warranties of the Issuer set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any

investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, or the Issuer, GP LLC, PAGP GP or any

of their respective directors or officers, or any person controlling the Issuer, (ii) acceptance of any Notes and payment therefor

in accordance with the terms of this Agreement, and (iii) any termination of this Agreement. A successor to any Underwriter or any

person controlling any Underwriter, or to the Issuer, GP LLC, PAGP GP or any of their respective directors or officers, or any person

controlling the Issuer shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this

Section 6.

7.             Conditions

to the Obligations of the Underwriters. The several obligations of the Underwriters to purchase the Notes are subject to the

following conditions:

(a)             All

be filed by the Issuer pursuant to Rule 433(d) of the Rules and Regulations shall have been filed with the Commission

within the applicable time period prescribed for such filing by Rule 433 of the Rules and Regulations. No stop order (i) suspending

the effectiveness of the Registration Statement or (ii) suspending or preventing the use of the most recent Preliminary Prospectus,

the Prospectus or any Issuer Free Writing Prospectus shall have been issued and no proceeding for that purpose shall have been instituted

or, to the knowledge of the Issuer or any Underwriter, threatened by the Commission, and any request of the Commission for additional

information (to be included in the Registration Statement or the Prospectus or otherwise) shall have been complied with to the reasonable

satisfaction of the Representatives.

(b)             Subsequent

to the Applicable Time, there shall not have occurred (i) any change, or any development involving a prospective change, that would

would materially adversely affect the market for the Notes, or (ii) any event or development relating to or involving any of the

Plains Entities or any executive officer or director of any of such entities that makes any statement made in the Prospectus untrue or

which, in the opinion of the Issuer and its counsel or the Underwriters and their counsel, requires the making of any addition to or

change in the Prospectus in order to state a material fact required by the Securities Act or any other law to be stated therein or necessary

in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, if amending or

supplementing the Prospectus to reflect such event or development would, in the Representatives’ opinion, materially adversely

affect the market for the Notes.

enforceable against each of them in accordance with its terms; provided that the enforceability thereof may be limited by (A) applicable

bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws from time to time in effect affecting creditors’

rights and remedies generally and by general principles of equity (regardless of whether such principles are considered in a proceeding

in equity or at law) and (B) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant

of good faith and fair dealing.

(v)            To

the knowledge of such counsel, Plains Canada has such Permits issued by the appropriate federal, provincial or regulatory authorities

as are necessary to own or lease its properties and to conduct its business as currently conducted and as proposed in the Registration

Statement, the Pricing Disclosure Package and the Prospectus to be conducted, subject to such qualifications as may be set forth in the

Registration Statement, the Pricing Disclosure Package and the Prospectus, and except for such Permits that, if not obtained would not

Default by

an Underwriter. If any one or more of the Underwriters shall fail or refuse to purchase Notes that it or they are obligated

to purchase hereunder on the Delivery Date, and the aggregate principal amount of Notes that such defaulting Underwriter or Underwriters

are obligated but fail or refuse to purchase is not more than one-tenth of the aggregate principal amount of the Notes that the Underwriters

are obligated to purchase on the Delivery Date, each non-defaulting Underwriter shall be obligated, severally, in the proportion that

the principal amount of Notes set forth opposite its name in Schedule I hereto bears to the aggregate principal amount of Notes

set forth opposite the names of all non-defaulting Underwriters or in such other proportion as the Representatives may specify in accordance

with the Agreement Among Underwriters of J.P. Morgan Securities LLC to purchase the Notes that such defaulting Underwriter or Underwriters

are obligated, but fail or refuse, to purchase. If any one or more of the Underwriters shall fail or refuse to purchase Notes that it

or they are obligated to purchase on the Delivery Date and the aggregate principal amount of Notes with respect to which such default

occurs is more than one-tenth of the aggregate principal amount of Notes that the Underwriters are obligated to purchase on the Delivery

Date and arrangements satisfactory to the Representatives and the Issuer for the purchase of such Notes by one or more non-defaulting

Underwriters or other party or parties approved by the Representatives and the Issuer are not made within 36 hours after such default,

this Agreement will terminate without liability on the part of any party hereto (other than any defaulting Underwriter). In any such

case that does not result in termination of this Agreement, either the Representatives or the Issuer shall have the right to postpone

the Delivery Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement

and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any

defaulting Underwriter from liability in respect of any such default of any such Underwriter under this Agreement. The term “Underwriter”

as used in this Agreement includes, for all purposes of this Agreement, any party not listed in Schedule I hereto who, with the

Representatives’ approval and the approval of the Issuer, purchases Notes that a defaulting Underwriter is obligated, but fails

or refuses, to purchase.

Any notice under this Section 9

may be given by telegram, telecopy or telephone but shall be subsequently confirmed by letter.

9.             Termination

of Agreement. This Agreement shall be subject to termination in the Representatives’ absolute discretion, without liability

on the part of any Underwriter to any Issuer, by notice to the Issuer prior to the Delivery Date, if at any time prior to such time (i) trading

in the Partnership’s Common Units shall have been suspended by the Commission or Nasdaq or trading in securities generally on the

New York Stock Exchange, the NYSE American LLC or the Nasdaq National Market shall have been suspended or limited or minimum prices shall

have been established; (ii) a banking moratorium shall have been declared either by federal or New York or Texas state authorities

or a material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred;

or (iii) there shall have occurred any outbreak or escalation of hostilities or acts of terrorism, declaration by the United States

of a national emergency or war or other calamity or crisis or any change in financial, political or economic conditions in the United

States or elsewhere, the effect of which on financial markets is such as to make it, in the sole judgment of the Underwriters, impractical

or inadvisable to proceed with the offering or delivery of the Notes as contemplated by the Prospectus (exclusive of any amendment or

supplement thereto). Notice of such termination may be given to the Issuer by telegram, telecopy or telephone and shall be subsequently

confirmed by letter.

that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research

reports with respect to the Issuer and/or the offering that differ from the views of their respective investment banking divisions. The

Issuer hereby waives and releases, to the fullest extent permitted by law, any claims that the Issuer may have against the Underwriters

with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts

and research departments may be different from or inconsistent with the views or advice communicated to the Issuer by such Underwriters’

investment banking divisions. The Issuer acknowledges that each of the Underwriters is a full-service securities firm and as such from

time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and

hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by

this Agreement.

13.           Recognition

of the U.S. Special Resolution Regimes.

(a)           In

the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer

in the Preliminary Prospectus. The Notes will not be guaranteed by any of our subsidiaries. The Notes will rank equally in right

of payment with any future unsecured indebtedness that we may incur from time to time if the terms of such indebtedness provide that

it ranks equally with the Notes in right of payment. The Notes will be effectively subordinated in right of payment to any secured

Schedule II-3

Optional

Interest Deferral:

The

terms of each series of Notes will provide that so long as no event of default (as defined in the Preliminary Prospectus) with respect

to the Notes of such series has occurred and is continuing, we may, at our option, defer interest payments on such series of Notes,

from time to time, for one or more deferral periods of up to 20 consecutive semi-annual Interest Payment Periods (as defined in the

Preliminary Prospectus) applicable to such series of Notes each (each such deferral period, commencing on the interest payment date

on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except

that no such Optional Deferral Period may extend beyond the final maturity date of the Notes of such series or end on a day other

than the day immediately preceding an interest payment date applicable to such series of Notes. In other words, with respect to each

series of Notes, we may declare at our discretion up to a ten-year interest payment moratorium and may choose to do that on one or

more occasions. No interest will be due or payable on the Notes of such series during an Optional Deferral Period, unless we elect,

at our option, to redeem any Notes of such series on any redemption date during such Optional Deferral Period, in which case all

accrued and unpaid interest on the Notes of such series to be redeemed to, but excluding, such redemption date will be due and payable

on such redemption date, or unless the principal of and interest on the Notes of such series shall have been declared due and payable

as the result of an event of default with respect to the Notes of such series, in which case, all accrued and unpaid interest, including,

to the extent permitted by applicable law, any interest on the deferred interest (“compound interest”), on the Notes

of such series shall become due and payable. We may elect, at our option, to extend the length of any Optional Deferral Period that

is shorter than 20 consecutive semi-annual Interest Payment Periods (so long as the entire Optional Deferral Period does not exceed

20 consecutive semi-annual Interest Payment Periods or extend beyond the final maturity date of the Notes of such series) and to

shorten the length of any Optional Deferral Period. With respect to each series of Notes, we cannot begin a new Optional Deferral

Period until we have paid all accrued and unpaid interest on the Notes of such series from any previous Optional Deferral Periods.

During any Optional Deferral Period applicable to a series of Notes, interest on the applicable series of Notes will continue to

accrue at the then-applicable interest rate on the Notes of such series (as reset from time to time on any Reset Date occurring during

such Optional Deferral Period in accordance with the terms of the Notes of such series). In addition, during any Optional Deferral

Period, interest on the deferred interest will accrue at the then-applicable interest rate on the Notes with respect to the Notes

of either series (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with

the terms of the Notes of such series), compounded semi-annually, to the extent permitted by applicable law.

Schedule II-4

Certain

Restrictions During an Optional Deferral Period:

During

any Optional Deferral Period, with respect to the Notes of either series, we (and our subsidiaries, as applicable) may not do any

of the following (subject to certain exceptions): (i) declare or pay dividends or distributions on any of our capital stock,

(ii) redeem, purchase, acquire or make a liquidation payment with respect to any of our capital stock, (iii) pay any principal,

interest or premium on, or repay, repurchase or redeem, any of our indebtedness that ranks equally with or junior to the Notes of

such series in right of payment, or (iv) make any payments with respect to any guarantees by us of any indebtedness if such

guarantees rank equally with or junior to the Notes of such series in right of payment.

Optional

Redemption:

The terms of each series of Notes will provide

that at our option, we may redeem some or all of the Notes of such series before their maturity, as follows:

·      in

whole or from time to time in part, (i) on any day in the period commencing on the date falling 90 days prior to the First Reset

Date (as defined in the Preliminary Prospectus) applicable to the Notes of such series and ending on (and including) such First Reset

Date and (ii) after such First Reset Date, on any applicable interest payment date, in each case at a redemption price in cash equal

to 100% of the principal amount of the Notes of such series to be redeemed, plus, subject to the terms described in the first paragraph

under “Description of the notes—Redemption—Redemption Procedures; Cancellation of Redemption” in the Preliminary

Prospectus, accrued and unpaid interest on the Notes of such series to be redeemed to, but excluding, such redemption date;

Schedule II-5

·      in

whole, but not in part, at any time within 120 days after the occurrence of a Tax Event (as defined in “Description of the notes—Redemption—Redemption

Following a Tax Event” in the Preliminary Prospectus) at a redemption price in cash equal to 100% of the principal amount of the

Notes of such series to be redeemed, plus, subject to the terms described in the first paragraph under “Description of the notes—Redemption—Redemption

Procedures; Cancellation of Redemption” in the Preliminary Prospectus, accrued and unpaid interest on the Notes of such series

to be redeemed to, but excluding, such redemption date; and

·      in

whole, but not in part, at any time during the continuance of and, in any event, within 120 days after the occurrence of, a Rating Agency

Event (as defined in the Preliminary Prospectus) at a redemption price in cash equal to 102% of the principal amount of the Notes of

such series to be redeemed, plus, subject to certain terms accrued and unpaid interest on the Notes of such series to be redeemed to,

but excluding, such redemption date.

the date of pricing of the notes (such settlement being referred to as “T+3”). Under Rule 15c6-1 of the Securities Exchange

before delivery will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify an alternate settlement

cycle at the time of any such trade to prevent failed settlement and should consult their own advisors.

CHIEF FINANCIAL OFFICER’S CERTIFICATE

September 9, 2026

The undersigned, in his capacity as the Chief

Financial Officer of Plains All American GP LLC, a Delaware limited liability company (the “General Partner”),

which is the general partner of Plains AAP, L.P., a Delaware limited liability partnership, which is the sole member of PAA GP LLC, a

Delaware limited liability company, which is the general partner of Plains All American Pipeline, L.P., a Delaware limited partnership

(the “Partnership”), does hereby certify as follows:

1. I

am providing this certificate (this “Certificate”) pursuant to

Section 7(n) of that certain Underwriting Agreement (the “Underwriting

Agreement”), dated as of September 9, 2026, by and among the Partnership

and J.P. Morgan Securities LLC whom J.P. Morgan Securities LLC, Citigroup Global Markets

Inc., Mizuho Securities USA LLC, MUFG Securities Americas Inc. and Truist Securities, Inc.

acting as the representatives of the several underwriters named in Schedule I thereto (the

“Underwriters”), relating to the sale to the Underwriters of $700,000,000

aggregate principal amount of 6.750% Series A Junior Subordinated Notes due 2056 (the

“Series A Notes”) and $800,000,000 aggregate principal amount

of 7.000% Series B Junior Subordinated Notes due 2056 (the “Series B

Notes,” and together with the Series A Notes, the “Notes”).

2. I

am the duly appointed, qualified and acting Chief Financial Officer of the General Partner

and am familiar with the accounting, operations and record systems of the Partnership. To

my knowledge after reasonable investigation, there has not been any material adverse change

in the financial position, results of operations, cash flows or working capital of the Partnership

since June 30, 2026. In addition, as of the date of this certificate, the total debt

of the Partnership is approximately $8.4 billion.

3. I have read the registration statement

on Form S-3 (File No. 333-281967), including the base prospectus, dated September 6,

2024, contained therein, together with the preliminary prospectus supplement and the final

prospectus supplement thereto, each dated September 9, 2026 (collectively, the “Registration

Statement”), and am familiar with the compilation of and have reviewed the

circled items contained in or incorporated by reference in the Registration Statement, such

circled items being attached hereto as Exhibit A (the “Identified Items”).

4. The

Identified Items include pro forma adjustments (the “Pro Forma Adjustments”)

to give effect to the purchase on October 31, 2025 of an aggregate 55% non-operated

equity interest in EPIC Crude Holdings, LP (“EPIC Crude Holdings”),

the entity that owns the EPIC Crude Oil Pipeline, and an aggregate 55% of the membership

interests in EPIC Crude Holdings GP, LLC (“EPIC GP”), the general

partner of EPIC Crude Holdings (the “EPIC 55% Transaction”) by

a wholly-owned subsidiary of the Partnership (the “Buyer”) and

the purchase effective as of November 1, 2025 of the remaining 45% equity interest in

EPIC Crude Holdings and the remaining 45% of the membership interests in EPIC GP by the Buyer

(the “EPIC 45% Transaction” and, together with the EPIC 55% Acquisition,

the “EPIC Transactions”) for the periods indicated.

Exhibit B

5. I

certify that the Pro Forma Adjustments were determined in good faith and based on assumptions

that provide a reasonable basis for presenting the effects of the EPIC Transactions for the

periods indicated. The assumptions and inputs used to calculate the Identified Items were

derived in good faith from (i) information in the Partnership’s accounting records

and (ii) other information made available to the Partnership by parties to, and in connection

with, the EPIC Transactions, in each case believed by me to be reliable. I, or members of

my staff under my supervision, have compared each of the Identified Items, as applicable,

to the corresponding amount in the records and information described above, or verified the

arithmetic accuracy of each such item, and found them to be in agreement in all material

respects.

6. Nothing

has come to my attention as the result of the procedures described above that causes me to

believe that the Identified Items are not accurate in all material respects.

7. Capitalized

terms used but not defined herein have the meanings assigned to them in the Underwriting

Agreement.

This certificate is to assist the Underwriters

in conducting and documenting their investigation of the affairs of the Partnership in connection with the offering of the Notes covered

by the Registration Statement, the Pricing Disclosure Package and the Prospectus.

or pursuant to such Board Resolutions and as set forth in such Officers’ Certificates or in any such Indenture supplemental hereto.

Section 2.04.

Execution of Debt Securities. The Debt Securities shall

be signed on behalf of the Partnership by the Chairman of the Board, the President or a Vice President of Plains All American GP. Such

signatures upon the Debt Securities may be the manual or facsimile signatures of the present or any future such authorized officers and

may be imprinted or otherwise reproduced on the Debt Securities. The seals of the Issuer, if any, may be in the form of a facsimile thereof

and may be impressed, affixed, imprinted or otherwise reproduced on the Debt Securities.

Only such Debt Securities

as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, signed manually by the Trustee,

shall be entitled to the benefits of the Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee upon any

Debt Security executed by the Issuer shall be conclusive evidence that the Debt Security so authenticated has been duly authenticated

and delivered hereunder.

In case any officer of Plains

All American GP who shall have signed any of the Debt Securities shall cease to be such officer before the Debt Securities so signed shall

have been authenticated and delivered by the Trustee, or disposed of by the Issuer, such Debt Securities nevertheless may be authenticated

and delivered or disposed of as though the Person who signed such Debt Securities had not ceased to be such officer of Plains All American

GP; and any Debt Security may be signed on behalf of the Issuer by such Persons as, at the actual date of the execution of such Debt Security,

shall be the proper officers of Plains All American GP, although at the date of such Debt Security or of the execution of the Indenture

any such Person was not such officer.

Section 2.05.

Authentication and Delivery of Debt Securities. At any time

and from time to time after the execution and delivery of the Indenture, the Issuer may deliver Debt Securities of any series executed

by the Issuer to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver said Debt Securities to or upon

an Issuer Order. The Debt Securities shall be dated the date of their authentication. In authenticating such Debt Securities and accepting

the additional responsibilities under the Indenture in relation to such Debt Securities, the Trustee shall be entitled to receive, and

(subject to Section 7.01) shall be fully protected in relying upon:

(1)

a copy of any Board Resolution of the Issuer, certified by the Secretary or Assistant Secretary of the Issuer, authorizing the

terms of issuance of any series of Debt Securities;

(2)

an executed supplemental Indenture, if any;

(3)

an Officers’ Certificate; and

(4)

an Opinion of Counsel prepared in accordance with Section 12.05 substantially to the effect that:

(a)

the form of such Debt Securities has been established by or pursuant to a Board Resolution of the Issuer or by a supplemental Indenture

as permitted by Section 2.01 in conformity with the provisions of the Indenture;

(b)

the terms of such Debt Securities have been established by or pursuant to a Board Resolution of the Issuer or by a supplemental

Indenture as permitted by Section 2.03 in conformity with the provisions of the Indenture; and

(c)

such Debt Securities, when authenticated and delivered by the Trustee and issued by the Issuer in the manner and subject to any

conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Issuer, enforceable in accordance

with their terms except as (i) the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting the

enforcement of creditors’ rights generally and (ii) rights of acceleration and the availability of equitable remedies may be

limited by equitable principles of general applicability.

Such Opinion of Counsel need

express no opinion as to whether a court in the United States would render a money judgment in a Currency other than Dollars.

The Trustee shall have the

right to decline to authenticate and deliver any Debt Securities under this Section 2.05 if the Trustee, being advised by counsel,

determines that such action may not lawfully be taken or if the Trustee in good faith by its board of directors or trustees, executive

committee or a trust committee of directors, trustees or vice presidents shall determine that such action would expose the Trustee to

personal liability to existing Holders.

The Trustee may appoint an

authenticating agent reasonably acceptable to the Issuer to authenticate Debt Securities of any series. Unless limited by the terms of

such appointment, an authenticating agent may authenticate Debt Securities whenever the Trustee may do so. Each reference in the Indenture

to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar,

paying agent or agent for service of notices and demands.

Section 2.06.

Denomination of Debt Securities. Unless otherwise provided

in the form of Debt Security for any series, the Debt Securities of each series shall be issuable only as Registered Securities in such

denominations as shall be specified or contemplated by Section 2.03. In the absence of any such specification with respect to the

Debt Securities of any series, the Debt Securities of such series shall be issuable in denominations of $1,000 and any integral multiple

thereof.

Section 2.07.

General Provisions for Registration of Transfer and Exchange.

(a) The Issuer shall keep or cause to be kept a register for each series of Registered Securities issued hereunder (hereinafter collectively

referred to as the “Debt Security Register”), in which, subject to such reasonable regulations as it may prescribe, the Issuer

shall provide for the registration of Registered Securities and the transfer of Registered Securities as in this Article II provided.

At all reasonable times the Debt Security Register shall be open for inspection by the Trustee. Subject to Section 2.15, upon due

presentment for registration of transfer of any Registered Security at any office or agency to be maintained by the Issuer in accordance

with the provisions of Section 4.02, the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the transferee

or transferees a new Registered Security or Registered Securities of authorized denominations for a like aggregate principal amount.

Unless and until otherwise

determined by a Board Resolution of the Issuer, the register of the Issuer for the purpose of registration, exchange or registration of

transfer of the Registered Securities shall be kept at the Corporate Trust Office of the Trustee and, for this purpose, the Trustee shall

be designated “Registrar”. No prior notice to the Holders of Debt Securities is required to effect the designation of a substitute

Registrar by the Issuer.

Registered Securities of any

series (other than a Global Security) may be exchanged for a like aggregate principal amount of Registered Securities of the same series

of other authorized denominations. Subject to Section 2.15, Registered Securities to be exchanged shall be surrendered at the office

or agency to be maintained by the Issuer as provided in Section 4.02, and the Issuer shall execute and the Trustee shall authenticate

and deliver in exchange therefor the Registered Security or Registered Securities that the Holder making the exchange shall be entitled

to receive.

(b)

All Registered Securities presented or surrendered for registration of transfer, exchange or payment shall (if so required by the

Issuer, the Trustee or the Registrar) be duly endorsed or be accompanied by a written instrument or instruments of transfer, in form satisfactory

to the Issuer, the Trustee and the Registrar, duly executed by the Registered Holder or his attorney duly authorized in writing.

All Debt Securities issued

in exchange for or upon transfer of Debt Securities shall be the legal, valid and binding obligations of the Issuer, evidencing the same

debt, and entitled to the same benefits under the Indenture as the Debt Securities surrendered for such exchange or transfer.

No service charge shall be

made for any exchange or registration of transfer of Debt Securities (except as provided by Section 2.09), but the Issuer may require

payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto, other than those expressly

provided in the Indenture to be made at the Issuer’s own expense or without expense or without charge to the Holders.

The Issuer shall not be required

(a) to issue, register the transfer of or exchange any Debt Securities of a series either (i) during a period beginning 15 Business

Days next preceding any selection for redemption or repurchase of Debt Securities of such series and ending on the close of business on

the day of giving the relevant notice of redemption or repurchase or (ii) between a record date and the next succeeding interest

payment date, or (b) to register the transfer of or exchange any Debt Security called for redemption or repurchase (except, in the

case of Debt Securities to be redeemed or repurchased in part, the portion not to be redeemed or repurchased).

Specific procedures for registration

of transfer and exchange of any series of Debt Securities may be set forth in the applicable supplemental Indenture for such Debt Securities.

Section 2.08.

Temporary Debt Securities. Pending the preparation of definitive

Debt Securities of any series, the Issuer may execute and the Trustee shall authenticate and deliver temporary Debt Securities (printed,

lithographed, photocopied, typewritten or otherwise produced) of any authorized denomination, and substantially in the form of the definitive

Debt Securities in lieu of which they are issued, and with such omissions, insertions and variations as may be appropriate for temporary

Debt Securities, all as may be determined by the Issuer with the concurrence of the Trustee. Temporary Debt Securities may contain such

reference to any provisions of the Indenture as may be appropriate.

Every temporary Debt Security

shall be executed by the Issuer and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and

with like effect, as the definitive Debt Securities.

If temporary Debt Securities

of any series are issued, the Issuer will cause definitive Debt Securities of such series to be prepared without unreasonable delay. After

the preparation of definitive Debt Securities of such series, the temporary Debt Securities of such series shall be exchangeable for definitive

Debt Securities of such series upon surrender of the temporary Debt Securities of such series at the office or agency of the Issuer at

a Place of Payment for such series, without charge to the Holder thereof, except as provided in Section 2.07 in connection with a

transfer, and upon surrender for cancellation of any one or more temporary Debt Securities of any series, the Issuer shall execute and

the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Debt Securities of the same series

of authorized denominations and of like tenor. Until so exchanged, temporary Debt Securities of any series shall in all respects be entitled

to the same benefits under the Indenture as definitive Debt Securities of such series, except as otherwise specified as contemplated by

Section 2.03 with respect to the payment of interest on Global Securities in temporary form.

Upon any exchange of a portion

of a temporary Global Security for a definitive Global Security or for the individual Debt Securities represented thereby pursuant to

Section 2.07 or this Section 2.08, the temporary Global Security shall be endorsed by the Trustee to reflect the reduction of

the principal amount evidenced thereby, whereupon the principal amount of such temporary Global Security shall be reduced for all purposes

by the amount so exchanged and endorsed.

Section 2.09.

Mutilated, Destroyed, Lost or Stolen Debt Securities. If

(i) any mutilated Debt Security is surrendered to the Trustee at the Corporate Trust Office of the Trustee (in the case of Registered

Securities) or (ii) the Issuer and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Debt

Security, and there is delivered to the Issuer and the Trustee such security or indemnity as may be required by them to save each of them

and any paying agent harmless, and neither the Issuer nor the Trustee receives written notice that such Debt Security has been acquired

by a bona fide purchaser, then the Issuer shall execute and, upon an Issuer Order, the Trustee shall authenticate and deliver, in exchange

for or in lieu of any such mutilated, destroyed, lost or stolen Debt Security, a new Debt Security of the same series of like tenor, form,

terms and principal amount, bearing a number not contemporaneously Outstanding. Upon the issuance of any substituted Debt Security, the

Issuer may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto

and any other expenses connected therewith. In case any Debt Security which has matured or is about to mature or which has been called

for redemption shall become mutilated or be destroyed, lost or stolen, the Issuer may, instead of issuing a substituted Debt Security,

pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Debt Security) if the applicant

for such payment shall furnish the Issuer and the Trustee with such security or indemnity as either may require to save it harmless from

all risk, however remote, and, in case of destruction, loss or theft, evidence to the satisfaction of the Issuer and the Trustee of the

destruction, loss or theft of such Debt Security and of the ownership thereof.

Every substituted Debt Security

of any series issued pursuant to the provisions of this Section 2.09 by virtue of the fact that any Debt Security is destroyed, lost

or stolen shall constitute an original additional contractual obligation of the Issuer, whether or not the destroyed, lost or stolen Debt

Security shall be found at any time, and shall be entitled to all the benefits of the Indenture equally and proportionately with any and

all other Debt Securities of that series duly issued hereunder. All Debt Securities shall be held and owned upon the express condition

that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities,

and shall preclude any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary

with respect to the replacement or payment of negotiable instruments or other securities without their surrender, in each case to the

fullest extent permitted by law.

Section 2.10.

Cancellation of Surrendered Debt Securities. All Debt Securities

surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to the Issuer or any paying agent or a

Registrar, be delivered to the Trustee for cancellation by it, or if surrendered to the Trustee, shall be canceled by it, and no Debt

Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of the Indenture. All canceled Debt

Securities held by the Trustee shall be disposed of by the Trustee in its customary manner. On request of the Issuer, the Trustee shall

deliver to the Issuer canceled Debt Securities held by the Trustee. If the Issuer shall acquire any of the Debt Securities, however, such

acquisition shall not operate as a redemption or satisfaction of the indebtedness represented thereby unless and until the same are delivered

or surrendered to the Trustee for cancellation. The Issuer may not issue new Debt Securities to replace Debt Securities it has redeemed,

paid or delivered to the Trustee for cancellation.

Section 2.11.

Provisions of the Indenture and Debt Securities for the Sole Benefit

of the Parties and the Holders. Nothing in the Indenture or in the Debt Securities, expressed or implied, shall give or be

construed to give to any Person, other than the parties hereto, the Holders or any Registrar or paying agent, any legal or equitable right,

remedy or claim under or in respect of the Indenture, or under any covenant, condition or provision herein contained, all its covenants,

conditions and provisions being for the sole benefit of the parties hereto, the Holders and any Registrar and paying agents.

Section 2.12.

Payment of Interest; Rights Preserved. (a) Interest

on any Registered Security that is payable and is punctually paid or duly provided for on any interest payment date shall be paid to the

Person in whose name such Registered Security is registered at the close of business on the regular record date for such interest notwithstanding

the cancellation of such Registered Security upon any transfer or exchange subsequent to the regular record date. Payment of interest

on Registered Securities shall be made at the Corporate Trust Office of the Trustee (except as otherwise specified pursuant to Section 2.03),

or at the option of the Issuer, by check mailed to the address of the Person entitled thereto as such address shall appear in the Debt

Security Register or, if provided pursuant to Section 2.03 and in accordance with arrangements satisfactory to the Trustee, at the

option of the Registered Holder by wire transfer to an account designated by the Registered Holder.

(b)

Subject to the foregoing provisions of this Section 2.12 and Section 2.17, each Debt Security of a particular series

delivered under the Indenture upon registration of transfer of or in exchange for or in lieu of any other Debt Security of the same series

shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Debt Security.

Section 2.13.

Securities Denominated in Foreign Currencies. (a) Except

as otherwise specified pursuant to Section 2.03 for Registered Securities of any series, payment of the principal of, and premium,

if any, and interest on, Registered Securities of such series will be made in Dollars.

(b)

For the purposes of calculating the principal amount of Debt Securities of any series denominated in a Foreign Currency or in units

of two or more Foreign Currencies for any purpose under the Indenture, the principal amount of such Debt Securities at any time Outstanding

shall be deemed to be the Dollar Equivalent of such principal amount as of the date of any such calculation.

In the event any Foreign Currency

or currencies or units of two or more Currencies in which any payment with respect to any series of Debt Securities may be made ceases

to be a freely convertible Currency on United States Currency markets, for any date thereafter on which payment of principal of, or premium,

if any, or interest on, the Debt Securities of a series is due, the Issuer shall select the Currency of payment for use on such date,

all as provided in the Debt Securities of such series. In such event, the Issuer shall, as provided in the Debt Securities of such series,

notify the Trustee of the Currency which it has selected to constitute the funds necessary to meet the Issuer’s obligations or such

payment date and of the amount of such Currency to be paid. Such amount shall be determined as provided in the Debt Securities of such

series. The payment to the Trustee with respect to such payment date shall be made by the Issuer solely in the Currency so selected.

Section 2.14.

Wire Transfers. Notwithstanding any other provision to the

contrary in the Indenture, the Issuer may make any payment of monies required to be deposited with the Trustee on account of principal

of, or premium, if any, or interest on, the Debt Securities (whether pursuant to optional or mandatory redemption payments, interest payments

or otherwise) by wire transfer of immediately available funds to an account designated by the Trustee on or before the date such moneys

are to be paid to the Holders of the Debt Securities in accordance with the terms hereof.

Section 2.15.

Securities Issuable in the Form of a Global Security.

(a)

If the Issuer shall establish pursuant to Sections 2.01 and 2.03 that the Debt Securities of a particular series are to be

issued in whole or in part in the form of one or more Global Securities, then the Issuer shall execute and the Trustee or its agent shall,

in accordance with Section 2.05, authenticate and deliver, such Global Security or Securities, which (i) shall represent, and

shall be denominated in an amount equal to the aggregate principal amount of, the Outstanding Debt Securities of such series to be represented

by such Global Security or Securities, or such portion thereof as the Issuer shall specify in an Officers’ Certificate, (ii) shall

be registered in the name of the Depositary for such Global Security or securities or its nominee, (iii) shall be delivered by the

Trustee or its agent to the Depositary or pursuant to the Depositary’s instruction and (iv) shall bear a legend substantially

to the following effect: “Unless and until it is exchanged in whole or in part for the individual Debt Securities represented hereby,

this Global Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the

Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or

a nominee of such successor Depositary”, or such other legend as may then be required by the Depositary for such Global Security

or Securities.

(b)

Notwithstanding any other provision of this Section 2.15 or of Section 2.07 to the contrary, and subject to the provisions

of paragraph (c) below, unless the terms of a Global Security expressly permit such Global Security to be exchanged in whole or in

part for definitive Debt Securities in registered form, a Global Security may be transferred, in whole but not in part and in the manner

provided in Section 2.07, only by the Depositary to a nominee of the Depositary for such Global Security, or by a nominee of the

Depositary to the Depositary or another nominee of the Depositary, or by the Depositary or a nominee of the Depositary to a successor

Depositary for such Global Security selected or approved by the Issuer, or to a nominee of such successor Depositary.

(c)

(i)   If at any time the Depositary for a Global Security or Securities notifies the Issuer that it is unwilling or unable to

continue as Depositary for such Global Security or Securities or if at any time the Depositary for the Debt Securities for such series

shall no longer be eligible or in good standing under the Exchange Act or other applicable statute, rule or regulation, the Issuer shall

appoint a successor Depositary with respect to such Global Security or Securities. If a successor Depositary for such Global Security

or Securities is not appointed by the Issuer within 90 days after the Issuer receive such notice or become aware of such ineligibility,

the Issuer shall execute, and the Trustee or its agent, upon receipt of an Issuer Order for the authentication and delivery of such individual

Debt Securities of such series in exchange for such Global Security, will authenticate and deliver, individual Debt Securities of such

series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the Global Security

in exchange for such Global Security or Securities.

(ii)

The Issuer may at any time and in its sole discretion determine that the Debt Securities of any series or portion thereof issued

or issuable in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such

event the Issuer will execute, and the Trustee, upon receipt of an Issuer Order for the authentication and delivery of individual Debt

Securities of such series in exchange in whole or in part for such Global Security, will authenticate and deliver individual Debt Securities

of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such series

or portion thereof in exchange for such Global Security or Securities.

(iii)

If specified by the Issuer pursuant to Sections 2.01 and 2.03 with respect to Debt Securities issued or issuable in the form

of a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for individual

Debt Securities of such series of like tenor and terms in definitive form on such terms as are acceptable to the Issuer, the Trustee and

such Depositary. Thereupon the Issuer shall execute, and the Trustee or its agent upon receipt of an Issuer Order for the authentication

and delivery of definitive Debt Securities of such series shall authenticate and deliver, without service charge, (1) to each Person

specified by such Depositary a new Debt Security or Securities of the same series of like tenor and terms and of any authorized denomination

as requested by such Person in aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the

Global Security, and (2) to such Depositary a new Global Security of like tenor and terms and in an authorized denomination equal

to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Debt

Securities delivered to Holders thereof, unless such Global Security is endorsed by the Trustee or other custodian to reflect a reduction

of such aggregate principal amount, in which case no new Global Security need be authenticated and delivered.

(iv)

In any exchange provided for in any of the preceding three paragraphs, the Issuer will execute and the Trustee or its agent will

authenticate and deliver individual Debt Securities. Upon the exchange of the entire principal amount of a Global Security for individual

Debt Securities, such Global Security shall be canceled by the Trustee or its agent. Except as provided in the preceding paragraph, Registered

Securities issued in exchange for a Global Security pursuant to this Section 2.15 shall be registered in such names and in such authorized

denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise,

shall instruct the Trustee or the Registrar. The Trustee or the Registrar shall deliver such Registered Securities to the Persons in whose

names such Registered Securities are so registered.

(v)

Payments in respect of the principal of and interest on any Debt Securities registered in the name of the Depositary or its nominee

will be payable to the Depositary or such nominee in its capacity as the registered owner of such Global Security. The Issuer and the

Trustee may treat the Person in whose name the Debt Securities, including the Global Security, are registered as the owner thereof for

the purpose of receiving such payments and for any and all other purposes whatsoever. None of the Issuer, the Trustee, any Registrar,

the paying agent or any agent of the Issuer or the Trustee will have any responsibility or liability for (a) any aspect of the records

relating to or payments made on account of the beneficial ownership interests of the Global Security by the Depositary or its nominee

or any of the Depositary’s direct or indirect participants, or for maintaining, supervising or reviewing any records of the Depositary,

its nominee or any of the Depositary’s direct or indirect participants relating to the beneficial ownership interests of the Global

Security, (b) the payments to the beneficial owners of the Global Security of amounts paid to the Depositary or its nominee, or (c) any

other matter relating to the actions and practices of the Depositary, its nominee or any of the Depositary’s direct or indirect

participants. None of the Issuer, the Trustee or any such agent will be liable for any delay by the Depositary, its nominee, or any of

the Depositary’s direct or indirect participants in identifying the beneficial owners of the Debt Securities, and the Issuer and

the Trustee may conclusively rely on, and will be protected in relying on, instructions from the Depositary or its nominee for all purposes

(including with respect to the registration and delivery, and the respective principal amounts, of the Debt Securities to be issued).

Section 2.16.

Medium Term Securities. Notwithstanding any contrary provision

herein, if all Debt Securities of a series are not to be originally issued at one time, it shall not be necessary for the Issuer to deliver

to the Trustee an Officers’ Certificate, a Board Resolution, a supplemental Indenture, an Opinion of Counsel or a written order

or any other document otherwise required pursuant to Section 2.01, 2.03, 2.05 or 12.05 at or prior to the time of authentication

of each Debt Security of such series if such documents are delivered to the Trustee or its agent at or prior to the authentication upon

original issuance of the first such Debt Security of such series to be issued; provided, that any subsequent request by the Issuer

to the Trustee to authenticate Debt Securities of such series upon original issuance shall constitute a representation and warranty by

the Issuer that, as of the date of such request, the statements made in the Officers’ Certificate delivered pursuant to Section 2.05

or 12.05 shall be true and correct as if made on such date and that the Opinion of Counsel delivered at or prior to such time of authentication

of an original issuance of Debt Securities shall specifically state that it shall relate to all subsequent issuances of Debt Securities

of such series that are identical to the Debt Securities issued in the first issuance of Debt Securities of such series.

An Issuer Order delivered

by the Issuer to the Trustee in the circumstances set forth in the preceding paragraph may provide that Debt Securities which are the

subject thereof will be authenticated and delivered by the Trustee or its agent on original issue from time to time upon the written order

of Persons designated in such written order and that such Persons are authorized to determine, consistent with the Officers’ Certificates,

supplemental Indenture or the applicable Board Resolutions relating to such written order, such terms and conditions of such Debt Securities

as are specified in such Officers’ Certificates, supplemental Indenture or such Board Resolutions.

Section 2.17.

Defaulted Interest. Any interest on any Debt Security of

a particular series which is payable, but is not punctually paid or duly provided for within applicable grace periods, on the dates and

in the manner provided in the Debt Securities of such series and in the Indenture (herein called “Defaulted Interest”) shall

forthwith cease to be payable to the Registered Holder thereof on the relevant record date by virtue of having been such Registered Holder,

and such Defaulted Interest may be paid by the Issuer, at its election in each case, as provided in clause (i) or (ii) below:

(i)

The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such

series are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed

in the following manner: The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each

such Registered Security of such series and the date of the proposed payment, and at the same time the Issuer shall deposit with the Trustee

an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements

satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust

for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a special

record date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date

of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee

shall promptly notify the Issuer of such special record date and, in the name and at the expense of the Issuer, shall cause notice of

the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first class postage prepaid, to each

Holder thereof at its address as it appears in the Debt Security Register, not less than 10 days prior to such special record date. Notice

of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest

shall be paid to the Persons in whose names the Registered Securities of such series are registered at the close of business on such special

record date.

(ii)

The Issuer may make payment of any Defaulted Interest on the Registered Securities of such series in any other lawful manner not

inconsistent with the requirements of any securities exchange on which the Registered Securities of such series may be listed, and upon

such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment pursuant

to this clause, such manner of payment shall be deemed practicable by the Trustee.

Section 2.18.

Judgments. The Issuer may provide pursuant to Section 2.03

for Debt Securities of any series that (a) the obligation, if any, of the Issuer to pay the principal of, and premium, if any, and

interest on, the Debt (b) Securities of any series in a Foreign Currency or Dollars (the “Designated Currency”) as may

be specified pursuant to Section 2.03 is of the essence and agrees that, to the fullest extent possible under applicable law, judgments

in respect of Debt Securities of such series shall be given in the Designated Currency; (c) the obligation of the Issuer to make

payments in the Designated Currency of the principal of, and premium, if any, and interest on, such Debt Securities shall, notwithstanding

any payment in any other Currency (whether pursuant to a judgment or otherwise), be discharged only to the extent of the amount in the

Designated Currency that the Holder receiving such payment may, in accordance with normal banking procedures, purchase with the sum paid

in such other Currency (after any premium and cost exchange) on the business day in the country of issue of the Designated Currency or

in the international banking community (in the case of a composite currency) immediately following the day on which such Holder receives

such payment; (d) if the amount in the Designated Currency that may be so purchased for any reason falls short of the amount originally

due, the Issuer shall pay such additional amounts as may be necessary to compensate for such shortfall; and (e) any obligation of

the Issuer not discharged by such payment shall be due as a separate and independent obligation and, until discharged as provided herein,

shall continue in full force and effect.

Section 2.19.

CUSIP Numbers. The Issuer in issuing the Debt Securities

may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices

of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness

of such numbers either as printed on the Debt Securities or as contained in any notice of a redemption and that reliance may be placed

only on the other identification numbers printed on the Debt Securities, and any such redemption shall not be affected by any defect in

or omission of such numbers. The Issuer will promptly notify the Trustee of any change in the “CUSIP” numbers.

Article III

Redemption of Debt Securities

Section 3.01.

Applicability of Article. The provisions of this Article

shall be applicable to the Debt Securities of any series which are redeemable before their Stated Maturity except as otherwise specified

as contemplated by Section 2.03 for Debt Securities of such series.

Section 3.02.

Notice of Redemption; Selection of Debt Securities. In case

the Issuer shall desire to exercise the right to redeem all or, as the case may be, any part of the Debt Securities of any series in accordance

with their terms, a Board Resolution of the Issuer or a supplemental Indenture, the Issuer shall fix a date for redemption and shall give

notice of such redemption at least 10 and not more than 60 days prior to the date fixed for redemption to the Holders of Debt Securities

of such series so to be redeemed as a whole or in part, in the manner provided in Section 12.03. Any redemption or notice of redemption

may, at the Issuer’s discretion, be subject to one or more conditions precedent, including completion of a corporate transaction.

If such redemption is subject to satisfaction of one or more conditions precedent, such notice may state that, in the Issuer’s discretion,

the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was delivered)

as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that

any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed, or such notice

may be rescinded at any time in the Issuer’s discretion if in the good faith judgment of the Issuer any or all of such conditions

will not be satisfied. The Issuer will provide written notice to the Trustee no later than 11:00 a.m., New York City time on the redemption

date if any such redemption has been rescinded or delayed. The notice if given in the manner herein provided shall be conclusively presumed

to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the

notice to the Holder of any Debt Security of a series designated for redemption as a whole or in part shall not affect the validity of

the proceedings for the redemption of any other Debt Security of such series.

Each such notice of redemption

shall specify the amount of Debt Securities of any series to be redeemed, the date fixed for redemption, the calculation of the redemption

price at which Debt Securities of such series are to be redeemed (but not the redemption price itself if it is not then determinable),

the Place or Places of Payment that payment will be made upon presentation and surrender of such Debt Securities, that any interest accrued

to the date fixed for redemption will be paid as specified in said notice, that the redemption is for a sinking fund payment (if applicable),

that on and after said date any interest thereon or on the portions thereof to be redeemed will cease to accrue, that in the case of Original

Issue Discount Securities original issue discount accrued after the date fixed for redemption will cease to accrue, the terms of the Debt

Securities of that series pursuant to which the Debt Securities of that series are being redeemed and that no representation is made as

to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Debt Securities of that series. If

less than all the Debt Securities of a series are to be redeemed the notice of redemption shall specify the CUSIP numbers of the Debt

Securities of that series to be redeemed. In case any Debt Security of a series is to be redeemed in part only, the notice of redemption

shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption,

upon surrender of such Debt Security, a new Debt Security or Debt Securities of that series will be issued in principal amount equal to

the unredeemed portion thereof.

At least five Business Days

before the giving of a notice of redemption, unless the Trustee consents to a shorter period, the Issuer shall give written notice to

the Trustee of the redemption date, the principal amount of Debt Securities to be redeemed and the series and terms of the Debt Securities

pursuant to which such redemption will occur. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel

to the effect that such redemption will comply with the conditions herein.

No later than 11:00 A.M.,

New York City time, on the redemption date for any Debt Securities, the Issuer shall deposit with the Trustee or with a paying agent (or,

if the Partnership is acting as its own paying agent, segregate and hold in trust) an amount of money in the Currency in which such Debt

Securities are denominated (except as provided pursuant to Section 2.03) sufficient to pay the redemption price of such Debt Securities

or any portions thereof that are to be redeemed on that date.

If less than all the Debt

Securities of like tenor and terms of a series are to be redeemed (other than pursuant to mandatory sinking fund redemptions), the Trustee

shall select the Debt Securities of that series or portions thereof (in multiples of $1,000) to be redeemed (i) if such Debt Securities

are listed on an exchange, in compliance with the requirements of the principal national securities exchange on which such Debt Securities

are listed, or (ii) if such Debt Securities are not listed on an exchange or such exchange has no selection requirements, on a pro

rata basis, by lot or by such other method as in its sole discretion the Trustee shall deem appropriate and fair. In any case where

more than one Debt Security of such series is registered in the same name, the Trustee in its discretion may treat the aggregate principal

amount so registered as if it were represented by one Debt Security of such series. The Trustee shall promptly notify the Issuer in writing

of the Debt Securities selected for redemption and, in the case of any Debt Securities selected for partial redemption, the principal

amount thereof to be redeemed. If any Debt Security called for redemption shall not be so paid upon surrender thereof on such redemption

date, the principal, premium, if any, and interest shall bear interest until paid from the redemption date at the rate borne by the Debt

Securities of that series. If less than all the Debt Securities of unlike tenor and terms of a series are to be redeemed, the particular

Debt Securities to be redeemed shall be selected by the Issuer. Provisions of the Indenture that apply to Debt Securities called for redemption

also apply to portions of Debt Securities called for redemption.

Section 3.03.

Payment of Debt Securities Called for Redemption. If notice

of redemption has been given as provided in Section 3.02, the Debt Securities or portions of Debt Securities of the series with respect

to which such notice has been given shall, subject to satisfaction of any conditions to the redemption, become due and payable on the

date and at the Place or Places of Payment stated in such notice at the applicable redemption price, together with any interest accrued

to the date fixed for redemption, and on and after said date (unless the Issuer shall default in the payment of such Debt Securities at

the applicable redemption price, together with any interest accrued to said date) any interest on the Debt Securities or portions of Debt

Securities of any series so called for redemption shall cease to accrue and any original issue discount in the case of Original Issue

Discount Securities shall cease to accrue. On presentation and surrender of such Debt Securities at the Place or Places of Payment in

said notice specified, the said Debt Securities or the specified portions thereof shall be paid and redeemed by the Issuer at the applicable

redemption price, together with any interest accrued thereon to the date fixed for redemption.

Any Debt Security that is

to be redeemed only in part shall be surrendered at the Corporate Trust Office of the Trustee or such other office or agency of the Issuer

as is specified pursuant to Section 2.03, if the Issuer, the Registrar or the Trustee so requires, due endorsement by, or a written

instrument of transfer in form satisfactory to the Issuer, the Registrar and the Trustee duly executed by, the Holder thereof or his attorney

duly authorized in writing, and the Issuer shall execute, and the Trustee shall authenticate and deliver to the Holder of such Debt Security

without service charge, a new Debt Security or Debt Securities of the same series, of like tenor and form, of any authorized denomination

as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the

Debt Security so surrendered; except that if a Global Security is so surrendered, the Issuer shall execute, and the Trustee shall authenticate

and deliver to the Depositary for such Global Security, without service charge, a new Global Security in a denomination equal to and in

exchange for the unredeemed portion of the principal of the Global Security so surrendered. In the case of a Debt Security providing appropriate

space for such notation, at the option of the Holder thereof, the Trustee, in lieu of delivering a new Debt Security or Debt Securities

as aforesaid, may make a notation on such Debt Security of the payment of the redeemed portion thereof.

Section 3.04.

Mandatory and Optional Sinking Funds. The minimum amount

of any sinking fund payment provided for by the terms of Debt Securities of any series, a Board Resolution or a supplemental Indenture

is herein referred to as a “mandatory sinking fund payment”, and any payment in excess of such minimum amount provided for

by the terms of Debt Securities of any series, a Board Resolution or a supplemental Indenture is herein referred to as an “optional

sinking fund payment.”

In lieu of making all or any

part of any mandatory sinking fund payment with respect to any Debt Securities of a series in cash, the Issuer may at its option (a) deliver

to the Trustee Debt Securities of that series theretofore purchased or otherwise acquired by the Issuer or (b) receive credit for

the principal amount of Debt Securities of that series which have been redeemed either at the election of the Issuer pursuant to the terms

of such Debt Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Debt Securities,

resolution or supplemental Indenture; provided, that such Debt Securities have not been previously so credited. Such Debt Securities

shall be received and credited for such purpose by the Trustee at the redemption price specified in such Debt Securities, the applicable

Board Resolution or supplemental Indenture for redemption through operation of the sinking fund and the amount of such mandatory sinking

fund payment shall be reduced accordingly.

Section 3.05.

Redemption of Debt Securities for Sinking Fund. Not less

than 60 days prior to each sinking fund payment date for any series of Debt Securities, the Issuer will deliver to the Trustee an Officers’

Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, any Board

Resolution or supplemental Indenture, the portion thereof, if any, which is to be satisfied by payment of cash in the Currency in which

the Debt Securities of such series are denominated (except as provided pursuant to Section 2.03) and the portion thereof, if any,

which is to be satisfied by delivering and crediting Debt Securities of that series pursuant to this Section 3.05 (which Debt Securities,

if not previously redeemed, will accompany such certificate) and whether the Issuer intend to exercise its right to make any permitted

optional sinking fund payment with respect to such series. Such certificate shall also state that no Event of Default has occurred and

is continuing with respect to such series.

Such certificate shall be

irrevocable and upon its delivery the Issuer shall be obligated to make the cash payment or payments therein referred to, if any, on or

before the next succeeding sinking fund payment date. Failure of the Issuer to deliver such certificate (or to deliver the Debt Securities

specified in this paragraph) shall not constitute a Default, but such failure shall require that the sinking fund payment due on the next

succeeding sinking fund payment date for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount

of such Debt Securities subject to a mandatory sinking fund payment without the option to deliver or credit Debt Securities as provided

in this Section 3.05 and without the right to make any optional sinking fund payment, if any, with respect to such series.

Any sinking fund payment or

payments (mandatory or optional) made in cash plus any unused balance of any preceding sinking fund payments made in cash which shall

equal or exceed $100,000 (or a lesser sum if the Issuer shall so request) with respect to the Debt Securities of any particular series

shall be applied by the Trustee on the sinking fund payment date on which such payment is made (or, if such payment is made before a sinking

fund payment date, on the sinking fund payment date following the date of such payment) to the redemption of such Debt Securities at the

redemption price specified in such Debt Securities, the applicable Board Resolution or supplemental Indenture for operation of the sinking

fund together with any accrued interest to the date fixed for redemption. Any sinking fund moneys not so applied or allocated by the Trustee

to the redemption of Debt Securities shall be added to the next cash sinking fund payment received by the Trustee for such series and,

together with such payment, shall be applied in accordance with the provisions of this Section 3.05. Any and all sinking fund moneys

with respect to the Debt Securities of any particular series held by the Trustee on the last sinking fund payment date with respect to

Debt Securities of such series and not held for the payment or redemption of particular Debt Securities shall be applied by the Trustee,

together with other moneys, if necessary, to be deposited sufficient for the purpose, to the payment of the principal of the Debt Securities

of that series at its Stated Maturity.

The Trustee shall select the

Debt Securities to be redeemed upon such sinking fund payment date in the manner specified in the last paragraph of Section 3.02

and the Issuer shall cause notice of the redemption thereof to be given in the manner provided in Section 3.02 except that the notice

of redemption shall also state that the Debt Securities are being redeemed by operation of the sinking fund. Such notice having been duly

given, the redemption of such Debt Securities shall be made upon the terms and in the manner stated in Section 3.03.

At least one business day

before each sinking fund payment date, the Issuer shall pay to the Trustee (or, if the Partnership is acting as its own paying agent,

the Partnership shall segregate and hold in trust) in cash a sum in the Currency in which the Debt Securities of such series are denominated

(except as provided pursuant to Section 2.03) equal to any interest accrued to the date fixed for redemption of Debt Securities or

portions thereof to be redeemed on such sinking fund payment date pursuant to this Section 3.05.

The Trustee shall not redeem

any Debt Securities of a series with sinking fund moneys or mail any notice of redemption of such Debt Securities by operation of the

sinking fund for such series during the continuance of a Default in payment of interest on such Debt Securities or of any Event of Default

(other than an Event of Default occurring as a consequence of this paragraph) with respect to such Debt Securities, except that if the

notice of redemption of any such Debt Securities shall theretofore have been mailed in accordance with the provisions hereof, the Trustee

shall redeem such Debt Securities if cash sufficient for that purpose shall be deposited with the Trustee for that purpose in accordance

with the terms of this Article III.

Except as aforesaid, any moneys

in the sinking fund for such series at the time when any such Default or Event of Default shall occur and any moneys thereafter paid into

such sinking fund shall, during the continuance of such Default or Event of Default, be held as security for the payment of such Debt

Securities; provided, however, that in case such Default or Event of Default shall have been cured or waived as provided

herein, such moneys shall thereafter be applied on the next sinking fund payment date for such Debt Securities on which such moneys may

be applied pursuant to the provisions of this Section 3.05.

Article IV

Covenants of the Issuer

Section 4.01.

Payment of Principal of, and Premium, If Any, and Interest on, Debt

Securities. The Issuer, for the benefit of each series of Debt Securities, will duly and punctually pay or cause to be paid

the principal of, and premium, if any, and interest on, each of the Debt Securities at the place, at the respective times and in the manner

provided herein and in the Debt Securities. Each installment of interest on the Debt Securities may at the Issuer’s option be paid

by mailing checks for such interest payable to the Person entitled thereto to the address of such Person as it appears on the Debt Security

Principal, premium and interest

in respect of Debt Securities of any series shall be considered paid on the date due if no later than 11:00 A.M., New York City time,

on such date the Trustee or any paying agent holds in accordance with the Indenture money sufficient to pay in the Currency in which the

Debt Securities of such series are denominated (except as provided pursuant to Section 2.03) all principal, premium and interest

The Issuer shall pay interest

or agency where Debt Securities of such series may be presented or surrendered for payment, where Debt Securities of such series may be

surrendered for transfer or exchange and where notices and demands to or upon the Issuer in respect of the Debt Securities of such series

and the Indenture may be served. The Issuer will give prompt written notice to the Trustee of the location, and any change in the location,

of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish

the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust

Office of the Trustee, and the Issuer hereby appoint the Trustee as its agent to receive all presentations, surrenders, notices and demands.

The Issuer may also from time

to time designate different or additional offices or agencies to be maintained for such purposes (in or outside of such Place of Payment),

and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall

in any manner relieve the Issuer of its obligations described in the preceding paragraph. The Issuer will give prompt written notice to

the Trustee of any such additional designation or rescission of designation and any change in the location of any such different or additional

office or agency.

Section 4.03.

Section 4.04.

Duties of Paying Agents, etc. (a) The Issuer shall

cause each paying agent, if any, other than the Trustee, to execute and deliver to the Trustee an instrument in which such agent shall

agree with the Trustee, subject to the provisions of this Section 4.04,

(i)

that it will hold all sums held by it as such agent for the payment of the principal of, and premium, if any, or interest on, the

Debt Securities of any series (whether such sums have been paid to it by the Issuer or by any other obligor on the Debt Securities of

such series) in trust for the benefit of the Holders of the Debt Securities of such series;

(ii)

that it will give the Trustee notice of any failure by the Issuer (or by any other obligor on the Debt Securities of such series)

to make any payment of the principal of and premium, if any, or interest on, the Debt Securities of such series when the same shall be

due and payable; and

(iii)

that it will at any time during the continuance of an Event of Default, upon the written request of the Trustee, forthwith pay

to the Trustee all sums so held by it as such agent.

(b)

If the Issuer or any of its Subsidiaries shall act as its own paying agent, it will, on or before 11:00 A.M., New York City time,

on each due date of the principal of, and premium, if any, or interest on, the Debt Securities if any, of any series, set aside, segregate

and hold in trust for the benefit of the Holders of the Debt Securities of such series a sum sufficient to pay such principal, premium,

if any, or interest so becoming due. The Issuer will promptly notify the Trustee of any failure by the Issuer or its Subsidiaries to take

such action or the failure by any other obligor on such Debt Securities to make any payment of the principal of, and premium, if any,

or interest on, such Debt Securities when the same shall be due and payable.

(c)

Anything in this Section 4.04 to the contrary notwithstanding, the Issuer may, at any time, for the purpose of obtaining a

it or any paying agent, as required by this Section 4.04, such sums to be held by the Trustee upon the same terms as those upon which

such sums were held by the Issuer or such paying agent.

(d)

Whenever the Issuer shall have one or more paying agents with respect to any series of Debt Securities, it will, prior to 11:00

A.M., New York City time, on each due date of the principal of, and premium, if any, or interest on, any Debt Securities of such series,

deposit with any such paying agent a sum sufficient to pay the principal, premium or interest so becoming due, such sum to be held in

trust for the benefit of the Persons entitled thereto, and (unless any such paying agent is the Trustee) the Issuer will promptly notify

the Trustee of its action or failure so to act.

(e)

Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 4.04

is subject to the provisions of Section 11.02.

(f)

Unless and until otherwise determined by the Issuer in Board Resolutions or pursuant to a supplemental Indenture, the Trustee will

act as paying agent under the Indenture. The Issuer may designate a substitute paying agent without prior notice to the Holders of Debt

Securities.

Section 4.05.

Statement by Officers as to Default. The Issuer will deliver

to the Trustee, on or before a date not more than four months after the end of each fiscal year of the Issuer (currently ending on December

of whom shall be the principal executive, financial or accounting officer of the Issuer, that (i) in the course of his performance

of his duties as an officer of Plains All American GP he would normally have knowledge of any Default, (ii) whether or not to the

the corporate, partnership or limited liability company existence and related rights and franchises (charges and statutory) of the Partnership

and each of its Subsidiaries; provided, however, that the Partnership shall not be required to preserve any such right or

franchise for the corporate, partnership or limited liability company existence of any such Subsidiary if the management of Plains All

American GP shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Partnership and

its Subsidiaries as a whole and that the loss thereof would not reasonably be expected to have a material adverse effect on the ability

of the Issuer or any obligor on the Debt Securities of any series to perform their obligations hereunder; and provided, further, however,

that the foregoing shall not prohibit a sale, transfer or conveyance of a Subsidiary of the Partnership or any of its assets in compliance

with the terms of the Indenture.

Section 4.07.

Calculation of Original Issue Discount. The Issuer shall

file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount

(including daily rates and accrual periods) accrued on Outstanding Original Issue Discount Debt Securities as of the end of such year

and (ii) such other specific information relating to such original issue discount as may then be relevant under the Code.

Section 4.08.

Stay, Extension and Usury Laws. The Issuer covenants (to

the extent that it may lawfully do so) that it shall not at any time insist upon, plead or in any manner whatsoever claim or take the

benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the

covenants or the performance of the Indenture; and the Issuer hereby expressly waives all benefit or advantage of any such law, and covenants

that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall

Debt Securities of such series for any purpose specified herein, by written request setting forth in reasonable detail the action proposed

to be taken at the meeting, and the Trustee shall not have made the first publication of the notice of such meeting within 30 days after

receipt of such request or shall not thereafter proceed to cause the meeting to be held as provided herein, then the Issuer or the Holders

of such series in the amount specified above, as the case may be, may determine the time and the place in Houston, Texas, in The Borough

of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) which the Partnership may be required

to file with the Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934; provided that

the Partnership shall be deemed to have filed copies of any such annual reports, documents or other reports with the Trustee to the extent

that such annual reports, documents or other reports are filed with the Commission via EDGAR (or any successor electronic delivery procedure).

The Issuer shall comply with the other provisions of Section 314(a) of the Trust Indenture Act.

(b)

The Issuer covenants and agrees, and any obligor hereunder shall covenant and agree, to file with the Trustee and the Commission,

in accordance with the rules and regulations prescribed from time to time by said Commission, such additional information, documents,

and reports with respect to compliance by the Issuer or such obligor, as the case may be, with the conditions and covenants provided for

in the Indenture as may be required from time to time by such rules and regulations.

(c)

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 notice of any information contained therein or determinable from information contained therein, including

the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’

Certificates).

Section 5.04.

Reports by Trustee. The Trustee shall transmit to Holders

such reports concerning the Trustee and its actions under the Indenture as may be required pursuant to the Trust Indenture Act at the

time and in the manner provided pursuant thereto.

Reports pursuant to this Section 5.04

shall be transmitted by mail:

(1)

to all Registered Holders, as the names and addresses of such Holders appear in the Debt Security Register; and

(2)

except in the cases of reports under Section 313(b)(2) of the Trust Indenture Act, to each holder of a Debt Security of any series

whose name and address appear in the information preserved at the time by the Trustee in accordance with Section 5.02.

A copy of each report at the

time of its mailing to Holders shall be filed with the Commission and each stock exchange (if any) on which the Debt Securities of any

series are listed. The Issuer agrees to notify promptly the Trustee whenever the Debt Securities of any series become listed on any stock

exchange and of any delisting thereof.

Section 5.05.

Record Dates for Action by Holders. If the Issuer shall

solicit from the Holders of Debt Securities of any series any action (including the making of any demand or request, the giving of any

direction, notice, consent or waiver or the taking of any other action), the Issuer may, at its option, by Board Resolution, fix in advance

a record date for the determination of Holders of Debt Securities entitled to take such action, but the Issuer shall have no obligation

to do so. Any such record date shall be fixed at the Issuer’s discretion. If such a record date is fixed, such action may be sought

or given before or after the record date, but only the Holders of Debt Securities of record at the close of business on such record date

shall be deemed to be Holders of Debt Securities for the purpose of determining whether Holders of the requisite proportion of Debt Securities

of such series Outstanding have authorized or agreed or consented to such action, and for that purpose the Debt Securities of such series

Outstanding shall be computed as of such record date.

Article VI

Remedies

of the Trustee and Holders in Event of Default

Section 6.01.

Events of Default. If any one or more of the following shall

have occurred and be continuing with respect to Debt Securities of any series (each of the following, an “Event of Default”):

(a)

the Issuer defaults for a period of 60 days in the payment when due of interest on any Debt Securities of that series; or

(b)

the Issuer defaults in the payment when due of principal of or premium, if any, on any Debt Securities of that series at maturity,

upon redemption or otherwise; or

(c)

default in the payment of any sinking fund payment with respect to any Debt Securities of that series as and when the same shall

become due and payable; or

(d)

failure on the part of the Issuer to comply with Article X; or

(e)

failure by the Issuer for 30 days after notice to comply to duly observe or perform any other of the covenants or agreements on

the part of the Issuer in the Debt Securities of that series in any Board Resolution authorizing the issuance of that series of Debt Securities,

in the Indenture with respect to such series or in any supplemental Indenture with respect to such series (other than a covenant a default

in the performance of which is elsewhere in this Section 6.01 specifically dealt with); or

(f)

pursuant to or within the meaning of Bankruptcy Law, the Issuer commences a voluntary case, consents to the entry of an order for

relief against it in an involuntary case, consents to the appointment of a custodian of it or for all or substantially all of its property,

makes a general assignment for the benefit of its creditors, or generally is not paying its debts as they become due; or

(g)

(i) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that is for relief against the Issuer

in an involuntary case, appoints a custodian of the Issuer, or orders the liquidation of the Issuer and (ii) such order or decree

remains unstayed and in effect for 60 consecutive days; or

(h)

any other Event of Default provided under the terms of the Debt Securities of that series; then and in each and every case that

an Event of Default with respect to Debt Securities of that series at the time outstanding occurs and is continuing, either the Trustee

or the Holders of at least 25% in aggregate principal amount of the Debt Securities of that series, may declare the principal of (or,

if the Debt Securities of that series are Original Issue Discount Debt Securities, such portion of the principal amount as may be specified

in the terms of that series) and interest on all the Debt Securities of that series to be due and payable immediately.

The Holders of a majority

in principal amount of the Debt Securities of a particular series by notice to the Trustee may rescind an acceleration and its consequences

if the rescission would not conflict with any judgment or decree already rendered and if all existing Events of Default have been cured

or waived except nonpayment of principal or 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 proceeding had been taken.

In case the Trustee or any

Holder shall have proceeded to enforce any right under the Indenture and such proceedings shall have been discontinued or abandoned because

of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee or such Holder, then and

in every such case 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.

The foregoing Events of Default

shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is

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.

The Issuer shall deliver to

the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event which

with the giving of notice and the lapse of time would become an Event of Default under clause (c), (d), (e), (f), (g) or (h), its

status and what action the Issuer is taking or propose to take with respect thereto.

Section 6.02.

Collection of Indebtedness by Trustee, etc. If an Event

of Default occurs and is continuing, 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 or enforce the performance

of any provision of the Debt Securities of the affected series or the Indenture, 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 any other obligor upon the Debt Securities of

such series (and collect in the manner provided by law out of the property of the Issuer or any other obligor upon the Debt Securities

of such series wherever situated the moneys adjudged or decreed to be payable).

In case there shall be pending

proceedings for the bankruptcy or for the reorganization of the Issuer or any other obligor upon the Debt Securities of any series under

Title 11 of the United States Code or any other Federal or State bankruptcy, insolvency or similar law, or in case a receiver, trustee

or other similar official shall have been appointed for its property, or in case of any other similar judicial proceedings relative to

the Issuer or any other obligor upon the Debt Securities of any series, its creditors or its property, the Trustee, irrespective of whether

the principal of Debt Securities of any series 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 6.02, shall be entitled and empowered,

by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any,

and interest (or, if the Debt Securities of such series are Original Issue Discount Debt Securities, such portion of the principal amount

as may be specified in the terms of such series) owing and unpaid in respect of the Debt Securities of such series, 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, its agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made,

by the Trustee except as a result of its negligence or bad faith) and of the Holders thereof allowed in any such judicial proceedings

relative to the Issuer, or any other obligor upon the Debt Securities of such series, its creditors or its property, and 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 such Holders and of the Trustee on their behalf, and any receiver, assignee or trustee in bankruptcy or reorganization is

hereby authorized by each of such Holders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making

of payments directly to such Holders, to pay to the Trustee such amount as shall be sufficient to cover reasonable compensation to the

Trustee, its agents, attorneys and counsel, and all other reasonable expenses and liabilities incurred, and all advances made, by the

Trustee except as a result of its negligence or bad faith.

All rights of action and of

asserting claims under the Indenture, or under any of the Debt Securities, of any series, may be enforced by the Trustee without the possession

of any such Debt Securities 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 (except for any

amounts payable to the Trustee pursuant to Section 7.06) shall be for the ratable benefit of the Holders of all the Debt Securities

in respect of which such action was taken.

In case of an Event of Default

hereunder the Trustee may in its discretion proceed to protect and enforce the rights vested in it by the Indenture by such appropriate

judicial proceedings as the Trustee shall deem necessary 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 the Indenture or in aid of the exercise of

any power granted in the Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture or by law.

Section 6.03.

Application of Moneys Collected by Trustee. Any moneys or

other property collected by the Trustee pursuant to Section 6.02 with respect to Debt Securities of any series shall be applied,

after giving effect to the provisions of Article XIII, in the order following, at the date or dates fixed by the Trustee for the

distribution of such moneys or other property, upon presentation of the several Debt Securities of such series in respect of which moneys

or other property have been collected, and the notation thereon of the payment, if only partially paid, and upon surrender thereof if

fully paid:

First: To the payment

of all money due the Trustee pursuant to Section 7.06;

Second: In case

the principal of the Outstanding Debt Securities in respect of which such moneys have been collected shall not have become due, to the

payment of interest on the Debt Securities of such series 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 rate or Yield to

Maturity (in the case of Original Issue Discount Debt Securities) specified in the Debt Securities of such series, such payments to be

made ratably to the Persons entitled thereto, without discrimination or preference;

Third: In case the

principal of the Outstanding Debt Securities in respect of which such moneys have been collected shall have become due, by declaration

or otherwise, to the payment of the whole amount then owing and unpaid upon the Debt Securities of such series for principal and premium,

if any, and interest, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected

by the Trustee) upon overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Debt Securities)

specified in the Debt Securities of such series; and, in case such moneys shall be insufficient to pay in full the whole amount so due

and unpaid upon the Debt Securities of such series, then to the payment of such principal and premium, if any, and interest, without preference

or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any installment

of interest over any other installment of interest, or of any Debt Security of such series over any Debt Security of such series, ratably

to the aggregate of such principal and premium, if any, and interest; and

Fourth: The remainder,

if any, shall be paid to the Issuer, its successors or assigns, or as a court of competent jurisdiction may direct.

The Trustee may fix a record

date and payment date for any payment to Holders pursuant to this Section 6.03. At least 15 days before such record date, the Issuer

shall mail to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid.

Section 6.04.

Limitation on Suits by Holders. No Holder of any Debt Security

of any series shall have any right by virtue or by availing of any provision of the Indenture to institute any action or proceeding at

law or in equity or in bankruptcy or otherwise, upon or under or with respect to the Indenture, or for the appointment of a receiver or

trustee, or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of

Default with respect to Debt Securities of that same series and of the continuance thereof and unless the Holders of not less than 33%

in aggregate principal amount of the Outstanding Debt Securities of that series shall have made written request upon the Trustee to institute

such action or proceedings in respect of such Event of Default in its own name as Trustee hereunder and shall have offered to the Trustee

such reasonable indemnity as it may require 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 proceedings

and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 6.06; it being understood

and intended, and being expressly covenanted by the Holder of every Debt Security with every other Holder and the Trustee, that no one

or more Holders shall have any right in any manner whatever by virtue or by availing of any provision of the Indenture to affect, disturb

or prejudice the rights of any Holders, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce

any right under the Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all such Holders.

For the protection and enforcement of the provisions of this Section 6.04, each and every Holder and the Trustee shall be entitled

to such relief as can be given either at law or in equity.

Notwithstanding any other

provision in the Indenture (but subject to Article XIII), the right of any Holder of any Debt Security to receive payment of the

principal of, and premium, if any, and (subject to Section 2.12) interest on, such Debt Security on or after the respective due dates

expressed in such Debt Security, and to institute suit for the enforcement of any such payment on or after such respective dates, shall

not be impaired or effected without the consent of such Holder.

Section 6.05.

Remedies Cumulative; Delay or Omission in Exercise of Rights Not a

Waiver of Default. All powers and remedies given by this Article VI to the Trustee or to the Holders shall, to the extent

permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or

the Holders, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained

in the Indenture, and no delay or omission of the Trustee or of any Holder to exercise any right or power accruing upon any Default occurring

and continuing as aforesaid, shall impair any such right or power, or shall be construed to be a waiver of any such Default or an acquiescence

therein; and, subject to the provisions of Section 6.04, every power and remedy given by this Article VI or by law to the Trustee

or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

Section 6.06.

Rights of Holders of Majority in Principal Amount of Debt Securities

to Direct Trustee and to Waive Default. The Holders of a majority in aggregate principal amount of the Debt Securities of any

series 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 Debt Securities of such series;

provided, however, that such direction shall not be otherwise than in accordance with law and the provisions of the Indenture,

and that subject to the provisions of Section 7.01, 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 so directed may not lawfully be taken, or if the Trustee shall by a Responsible

Officer or officers determine that the action so directed would involve it in personal liability or would be prejudicial to Holders of

Debt Securities of such series not taking part in such direction; and provided further, however, that nothing in the Indenture contained

shall impair the right of the Trustee to take any action deemed proper by the Trustee and which is not inconsistent with such direction

by such Holders. Prior to the acceleration of the maturity of the Debt Securities of any series, as provided in Section 6.01, the

Holders of a majority in aggregate principal amount of the Debt Securities of that series at the time Outstanding by notice to the Trustee

may on behalf of the Holders of all the Debt Securities of that series waive any past Default or Event of Default and its consequences

for that series specified in the terms thereof as contemplated by Section 2.03, except (i) a Default in the payment of the principal

of, and premium, if any, or interest on, any of the Debt Securities and (ii) a Default in respect of a provision that under Section 9.02

cannot be amended, supplemented or waived without the consent of each Holder affected thereby. In case of any such waiver, such Default

shall cease to exist, any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture, and

the Issuer, the Trustee and the Holders of the Debt Securities of that series 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.

Section 6.07.

Trustee to Give Notice of Defaults Known to It, but May Withhold Such

Notice in Certain Circumstances. The Trustee shall, within 90 days after the occurrence of a Default known to it with respect

to a series of Debt Securities give to the Holders thereof, in the manner provided in Section 12.03, notice of all Defaults with

respect to such series known to the Trustee, unless such Defaults shall have been cured or waived before the giving of such notice; provided

that, except in the case of Default in the payment of the principal of, or premium, if any, or interest on, any of the Debt Securities

of such series or in the making of any sinking fund payment with respect to the Debt Securities of such series, the Trustee shall be protected

in withholding such notice if and so long as the committee of Responsible Officers of the Trustee in good faith determine that the withholding

of such notice is in the interests of the Holders thereof.

Section 6.08.

Requirement of an Undertaking To Pay Costs in Certain Suits under the

Indenture or Against the Trustee. All parties to the Indenture agree, and each Holder of any Debt Security 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 the Indenture, or in any suit against the Trustee for any action taken 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 in the manner and to the extent provided in the Trust Indenture

Act, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, 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 6.08 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 ten percent in principal amount of the Outstanding Debt Securities of that series

or to any suit instituted by any Holder for the enforcement of the payment of the principal of, or premium, if any, or interest on, any

Debt Security on or after the due date for such payment expressed in such Debt Security.

Article VII

Concerning

the Trustee

Section 7.01.

Certain Duties and Responsibilities. The Trustee, prior

to the occurrence of an Event of Default 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 the Indenture. In case an Event of Default has occurred (which

has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by the 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 his own

affairs.

No provision of the 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)

this subsection shall not be construed to limit the effect of the first paragraph of this Section 7.01;

(b)

prior to the occurrence of an Event of Default with respect to the Debt Securities of a series and after the curing or waiving

of all Events of Default with respect to such series which may have occurred:

(1)           the

duties and obligations of the Trustee with respect to Debt Securities of any series shall be determined solely by the express provisions

of the Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations with respect to such series

as are specifically set forth in the Indenture, and no implied covenants or obligations with respect to such series shall be read into

the Indenture against the Trustee; and

(2)           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 certificates or opinions furnished to the Trustee and conforming to the requirements of the

Indenture; but in the case of any such 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

the Indenture;

(c)

the Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer, unless it shall be proved

that the Trustee was negligent in ascertaining the pertinent facts; and

(d)

the Trustee shall not be liable with respect to any action taken or omitted to be taken by it with respect to Debt Securities of

any series in good faith in accordance with the direction of the Holders of not less than a majority in aggregate principal amount of

the Outstanding Debt Securities of that series 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 the Indenture with respect to Debt Securities of such

series. None of the provisions of the Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any personal

financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there shall

be reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably

assured to it.

Whether or not therein expressly

so provided, every provision of the Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee

shall be subject to the provisions of this Section.

Section 7.02.

Certain Rights of Trustee. Except as otherwise provided

in Section 7.01:

(a)

the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate,

statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note or other paper or document (whether

in its original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b)

any request, direction, order or demand of the Issuer mentioned herein shall be sufficiently evidenced by an Issuer Order (unless

other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy

thereof certified by the Secretary or an Assistant Secretary of Plains All American GP;

(c)

the Trustee may consult with counsel of its own selection, and the advice of such counsel or any Opinion of Counsel shall be full

and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance

with such advice or Opinion of Counsel;

(d)

the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by the Indenture at the request,

order or direction of any of the Holders of Debt Securities of any series pursuant to the provisions of the Indenture, unless such Holders

shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which

may be incurred therein or thereby;

(e)

the Trustee shall not be liable for any action taken or omitted by it in good faith and reasonably believed by it to be authorized

or within the discretion or rights or powers conferred upon it by the Indenture;

(f)

prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, 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, direction, consent, order, approval or other paper or document, unless requested in writing to do so by the Holders

of a majority in aggregate principal amount of the then outstanding Debt Securities of a series affected by such matter; provided,

however, 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 not, in the opinion of the Trustee, reasonably assured to the Trustee by the security afforded

to it by the terms of the Indenture, the Trustee may require indemnity reasonably satisfactory to it against such costs, expenses or liabilities

as a condition to so proceeding; the Trustee shall be entitled to examine the books, records and premises of the Issuer during ordinary

business hours and for any purpose relevant to the Indenture, personally or by an agent or attorney at the sole cost of the Issuer and

shall incur no liability or additional liability of any kind by reason of such inquiry or investigation;

(g)

the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through

agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed

by it with due care hereunder;

(h)

if any property other than cash shall at any time be subject to a Lien in favor of the Holders, the Trustee, if and to the extent

authorized by a receivership or bankruptcy court of competent jurisdiction or by the supplemental instrument subjecting such property

to such Lien, shall be entitled to make advances for the purpose of preserving such property or of discharging tax Liens or other prior

Liens or encumbrances thereon; and

(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 Debt Securities and the Indenture; and

(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 to each agent, custodian

and other Person employed by the Trustee to act hereunder.

Section 7.03.

Trustee Not Liable for Recitals in Indenture or in Debt Securities.

The recitals contained herein and in the Debt Securities (except the Trustee’s certificate 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 representations

as to the validity or sufficiency of the Indenture or of the Debt Securities of any series, except that the Trustee represents that it

is duly authorized to execute and deliver the Indenture, authenticate the Debt Securities and perform its obligations hereunder, and that

the statements made by it or to be made by it in a Statement of Eligibility and Qualification 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 Debt Securities or of the proceeds

thereof.

Section 7.04.

Trustee, Paying Agent or Registrar May Own Debt Securities.

The Trustee or any paying agent or Registrar, in its individual or any other capacity, may become the owner or pledgee of Debt Securities

and subject to the provisions of the Trust Indenture Act relating to conflicts of interest and preferential claims may otherwise deal

with the Issuer with the same rights it would have if it were not Trustee, paying agent or Registrar; provided, however,

that if the Trustee acquires any such conflicting interest and an Event of Default or Default has occurred and is continuing, the Trustee

must eliminate such conflict within 90 days, apply to the Commission for permission to continue as trustee or resign.

Section 7.05.

Moneys Received by Trustee to Be Held in Trust. Subject

to the provisions of Section 11.02, 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 law.

The Trustee shall be under no liability for interest on any moneys received by it hereunder. So long as no Event of Default shall have

occurred and be continuing, all interest allowed on any such moneys shall be paid from time to time to the Issuer upon an Issuer Order.

Section 7.06.

Compensation and Reimbursement. The Issuer covenants and

agrees to pay in Dollars to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services

rendered by it hereunder (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express

trust), and, except as otherwise expressly provided herein, the Issuer will pay or reimburse in Dollars the Trustee upon its request for

all expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of the Indenture (including

the reasonable compensation and the expenses and disbursements of its agents, attorneys and counsel and of all Persons not regularly in

its employ) except any such expense, disbursement or advances as may arise from its negligence or bad faith. The Issuer also covenants

to fully indemnify in Dollars the Trustee and any predecessor Trustee for, and to hold it harmless against, any and all loss, liability,

claim, damage or expense incurred without negligence or willful misconduct on the part of the Trustee, arising out of or in connection

with the acceptance or administration of this trust or trusts hereunder, including the costs and expenses of defending itself against

any claim of liability in connection with the exercise or performance of any of its powers or duties hereunder. The obligations of the

Issuer under this Section 7.06 to compensate and indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements

and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of the Indenture. The

Issuer and the Holders agree that such additional indebtedness shall be secured by a Lien prior to that of the Debt Securities upon all

property and funds held or collected by the Trustee, as such, except funds held in trust for the payment of principal of, and premium,

if any, or interest on, particular Debt Securities.

When the Trustee incurs expenses

or renders services after an Event of Default specified in Section 6.01(g) or (h) occurs, the expenses and the compensation for the

services are intended to constitute expenses of administration under any bankruptcy, insolvency, reorganization or other similar law.

Section 7.07.

Right of Trustee to Rely on an Officers’ Certificate Where No

Other Evidence Specifically Prescribed. Except as otherwise provided in Section 7.01, whenever in the administration of

the provisions of the 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 the Indenture upon the faith thereof.

Section 7.08.

Separate Trustee; Replacement of Trustee. The Issuer may,

but need not, appoint a separate Trustee for any one or more series of Debt Securities. The Trustee may resign with respect to one or

more or all series of Debt Securities at any time by giving notice to the Issuer. The Holders of a majority in principal amount of the

Debt Securities of a particular series may remove the Trustee for such series and only such series by so notifying the Trustee and may

appoint a successor Trustee. The Issuer shall remove the Trustee if:

(1)

the Trustee fails to comply with Section 7.10;

(2)

the Trustee is adjudged bankrupt or insolvent;

(3)

a receiver or other public officer takes charge of the Trustee or its property; or

(4)

the Trustee otherwise becomes incapable of acting.

If the Trustee resigns, is

removed by the Issuer or by the Holders of a majority in principal amount of the Debt Securities of a particular series and such Holders

do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in

such event being referred to herein as the retiring Trustee), the Issuer shall promptly appoint a successor Trustee. No resignation or

removal of the Trustee and no appointment of a successor Trustee shall become effective until the acceptance of appointment by the successor

Trustee in accordance with the applicable requirements of this Section 7.08.

A successor Trustee shall

deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation or removal of the

retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under the

Indenture. The successor Trustee shall mail a notice of its succession to Holders of Debt Securities of each applicable series. The retiring

Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.06.

If a successor Trustee does

not take office within 60 days after the retiring Trustee gives notice of resignation or is removed, the retiring Trustee or the Holders

of 25% in principal amount of the Debt Securities of any applicable series may petition any court of competent jurisdiction for the appointment

of a successor Trustee for the Debt Securities of such series.

If the Trustee fails to comply

with Section 7.10, any Holder of Debt Securities of any applicable series may petition at the expense of the Issuer any court of

competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee for the Debt Securities of such series.

Notwithstanding the replacement

of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.06 shall continue for the benefit

of the retiring Trustee.

In the case of the appointment

hereunder of a separate or successor Trustee with respect to the Debt Securities of one or more series, the Issuer, any retiring Trustee

and each successor or separate Trustee with respect to the Debt Securities of any applicable series shall execute and deliver an Indenture

supplemental hereto (1) which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights,

powers, trusts and duties of any retiring Trustee with respect to the Debt Securities of any series as to which any such retiring Trustee

is not retiring shall continue to be vested in such retiring Trustee and (2) that shall add to or change any of the provisions of

the Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee,

it being understood that nothing herein or in such supplemental Indenture shall constitute such Trustees co-trustees of the same trust

and that each such separate, retiring or successor Trustee shall be Trustee of a trust or trusts hereunder separate and apart from any

trust or trusts hereunder administered by any other such Trustee.

Section 7.09.

Successor Trustee by Merger. If the Trustee consolidates

with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to, another corporation

or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the

successor Trustee, provided such Person shall be otherwise qualified and eligible under this Article VII, without the execution or

filing of any paper or any further act on the part of any of the parties hereto. As soon as practicable, the successor Trustee shall mail

a notice of its succession to the Issuer and the Holders of the Debt Securities then Outstanding.

In case at the time such successor

or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by the Indenture any of the Debt

Securities 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 Debt Securities so authenticated; and in case at that time any of the Debt Securities shall

not have been authenticated, any successor to the Trustee may authenticate such Debt Securities either in the name of any predecessor

hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is

anywhere in the Debt Securities or in the Indenture provided that the certificate of the Trustee shall have.

Section 7.10.

Eligibility; Disqualification. The Trustee shall at all

times satisfy the requirements of Section 310(a) of the Trust Indenture Act. The Trustee shall have a combined capital and surplus of

at least $50,000,000, as set forth in its most recently published annual report of condition. No obligor upon the Debt Securities of a

particular series or Person directly or indirectly controlling, controlled by or under common control with such obligor shall serve as

Trustee upon the Debt Securities of such series. The Trustee shall comply with Section 310(b) of the Trust Indenture Act; provided,

however, that there shall be excluded from the operation of Section 310(b)(1) of the Trust Indenture Act the Indenture or any 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 Section 310(b)(1) of the Trust Indenture Act are met.

Section 7.11.

Preferential Collection of Claims Against

Issuer. The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship

listed in Section 311(b) of the Trust Indenture Act. A Trustee who had resigned or been removed shall be subject to Section 311(a)

of the Trust Indenture Act to the extent indicated therein.

Section 7.12.

Compliance with Tax Laws. The Trustee hereby agrees to comply

with all U.S. Federal income tax information reporting and withholding requirements applicable to it with respect to payments of principal,

premium (if any) and interest on the Debt Securities, whether acting as Trustee, Security Registrar, paying agent or otherwise with respect

to the Debt Securities.

Article VIII

Concerning

the Holders

Section 8.01.

Evidence of Action by Holders. Whenever in the Indenture

it is provided that the Holders of a specified percentage in aggregate principal amount of the Debt Securities of any or all series may

take action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of any

other action) the fact that at the time of taking any such action the Holders of such specified percentage have joined therein may be

evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy

appointed in writing, (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in

accordance with the provisions of Section 5.02 or (c) by a combination of such instrument or instruments and any such record

of such a meeting of Holders.

Section 8.02.

Proof of Execution of Instruments and of Holding of Debt Securities.

Subject to the provisions of Sections 7.01, 7.02 and 12.09, proof of the execution of any instrument by a Holder or his agent or

proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such

manner as shall be satisfactory to the Trustee.

The ownership of Registered

Securities of any series shall be proved by the Debt Security Register or by a certificate of the Registrar for such series.

The Trustee may require such

additional proof of any matter referred to in this Section 8.02 as it shall deem necessary.

Section 8.03.

Who May Be Deemed Owner of Debt Securities. Prior to due

presentment for registration of transfer of any Registered Security, the Issuer, the Trustee, any paying agent and any Registrar may deem

and treat the Person in whose name any Registered Security shall be registered upon the books of the Issuer as the absolute owner of such

Registered Security (whether or not such Registered Security 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 premium, if any, and (subject to Section 2.12)

interest on such Registered Security and for all other purposes, and neither the Issuer nor the Trustee nor any paying agent nor any Registrar

shall be affected by any notice to the contrary; and all such payments so made to any such Holder for the time being, 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 Registered Security.

Section 8.04.

Instruments Executed by Holders Bind Future Holders. At

any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the

Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in the Indenture in connection

with such action and subject to the following paragraph, any Holder of a Debt Security which is shown by the evidence to be included in

the Debt Securities the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate

Trust Office of the Trustee and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Debt

Security. Except as aforesaid any such action taken by the Holder of any Debt Security shall be conclusive and binding upon such Holder

and upon all future Holders and owners of such Debt Security and of any Debt Security issued upon transfer thereof or in exchange or substitution

therefor, irrespective of whether or not any notation in regard thereto is made upon such Debt Security or such other Debt Securities.

Any action taken by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in the

Indenture in connection with such action shall be conclusively binding upon the Issuer, the Trustee and the Holders of all the Debt Securities

of such series.

The Issuer may, but shall

not be obligated to, fix a record date for the purpose of determining the Holders of Registered Securities entitled to give their consent

or take any other action required or permitted to be taken pursuant to the Indenture. If a record date is fixed, then notwithstanding

the immediately preceding paragraph, those Persons who were Holders of Registered Securities at such record date (or their duly designated

proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such

action, whether or not such Persons continue to be Holders of Registered Securities after such record date. No such consent shall be valid

or effective for more than 120 days after such record date unless the written consent of the Holders of the percentage in aggregate principal

amount of the Debt Securities of such series specified in the Indenture shall have been received within such 120-day period.

Article IX

Amendment,

Supplement and Waiver

Section 9.01.

Without Consent of Holders of Debt Securities. The Issuer

and the Trustee may from time to time and at any time, without the consent of Holders, enter into an Indenture or Indentures supplemental

that the uncertificated Debt Securities are described in Section 163(f)(2)(B) of the Code;

(c)

to provide for the assumption of the Issuer’s obligations to Holders pursuant to Article X;

(d)

to comply with the requirements of the Commission to permit the qualification of the Indenture or any Indenture supplemental hereto

under the Trust Indenture Act as then in effect, except that nothing herein contained shall permit or authorize the inclusion in any Indenture

supplemental hereto of the provisions referred to in Section 316(a)(2) of the Trust Indenture Act;

(g)

to evidence or provide for the acceptance of appointment hereunder by a successor or separate Trustee with respect to the Debt

affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise.

Any supplemental Indenture

authorized by the provisions of this Section 9.01 may be executed by the Issuer, any guarantors with respect to any Debt Securities

and the Trustee without the consent of the Holders of any of the Debt Securities at the time outstanding, notwithstanding any of the provisions

of Section 9.02.

After an amendment under this

Section 9.01 becomes effective, the Issuer shall mail to Holders of Debt Securities of each series affected thereby a notice briefly

describing such amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the

validity of an amendment under this Section 9.01.

Section 9.02.

With Consent of Holders of Debt Securities. Without notice

to any Holder but with the consent (evidenced as provided in Section 8.01) of the Holders of a majority in aggregate principal amount

of the outstanding Debt Securities of each series affected by such supplemental Indenture, (a) the Issuer and the Trustee may from

time to time and at any time enter into an Indenture or Indentures supplemental hereto (which shall conform to the provisions of the Trust

Indenture Act as in force at the date of execution thereof) for the purpose of adding any provisions to or changing in any manner or eliminating

any of the provisions of the Indenture or of any supplemental Indenture or of modifying in any manner the rights of the Holders of the

Debt Securities of such series, and (b) subject to the Sections 6.04 and 6.08, any existing Default or Events of Default or

compliance with any provision of the Indenture or the Debt Securities of such series may be waived; provided, that no such supplemental

under the Indenture, release any security that may have been granted in respect of the Debt Securities; (vii) make any Debt Security

series); (x) except as otherwise permitted under the Indenture with respect to Debt Securities that are guaranteed, release any guarantor

from its obligations under the Indenture or under its guarantee or change any guarantee in any manner that would adversely affect the

rights of Holders of such Debt Securities; (xi) make any change in Article XIII that adversely affects the rights of any Holder

under Article XIII; or (xii) make any change in Section 6.06 or this Section 9.02.

A supplemental Indenture which

changes or eliminates any covenant or other provision of the Indenture which has been expressly included solely for the benefit of one

or more particular series of Debt Securities or which modifies the rights of the Holders of Debt Securities of such series with respect

to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the Holders of Debt Securities of

any other series.

Upon the request of the Issuer,

accompanied by copies of Board Resolutions authorizing the execution of any such supplemental Indenture, and upon the filing with the

Trustee of evidence of the consent of Holders as aforesaid, the Trustee shall join with the Issuer and any guarantors with respect to

any Debt Securities in the execution of such supplemental Indenture unless such supplemental Indenture affects the Trustee’s own

rights, duties or immunities under the Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated

to enter into such supplemental Indenture.

It shall not be necessary

for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed supplemental Indenture, but

it shall be sufficient if such consent shall approve the substance thereof.

An amendment under this Section 9.02

may not make any change that adversely affects the rights under Article XIII of any holder of Senior Indebtedness then Outstanding

unless the holders of such Senior Indebtedness (or any group or Representative thereof authorized to give a consent) consents to such

change.

After an amendment or waiver

under this Section 9.02 becomes effective, the Issuer shall mail to Holders of Debt Securities of each series affected thereby a

notice briefly describing such amendment or waiver. The failure to give such notice to all such Holders, or any defect therein, shall

not impair or affect the validity of an amendment or waiver under this Section 9.02.

Section 9.03.

Effect of Supplemental Indentures. Upon the execution of

any supplemental Indenture pursuant to the provisions of this Article IX, the 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 the Indenture

of the Trustee, the Issuer and the Holders 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 supplemental Indenture shall be and be deemed to be part

of the terms and conditions of the Indenture for any and all purposes.

The Trustee, subject to the

provisions of Sections 7.01 and 7.02, may receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence

that any such supplemental Indenture complies with the provisions of this Article IX.

Section 9.04.

Debt Securities May Bear Notation of Changes by Supplemental Indentures.

Debt Securities of any series authenticated and delivered after the execution of any supplemental Indenture pursuant to the provisions

of this Article IX may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided

for in such supplemental Indenture. New Debt Securities of any series so modified as to conform, in the opinion of the Trustee and the

Board of Directors, to any modification of the Indenture contained in any such supplemental Indenture may be prepared and executed by

the Issuer, authenticated by the Trustee and delivered in exchange for the Debt Securities of such series then outstanding. Failure to

make the appropriate notation or to issue a new Debt Security of such series shall not affect the validity of such amendment.

Article X

Consolidation,

Merger, Sale or Conveyance

Section 10.01.

Consolidations and Mergers of the Issuer. The Issuer may

not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not the Issuer is the survivor); or

(2) sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or

more related transactions, to another Person; unless:

(1)

either (a) the Issuer is the surviving entity of such transaction; or (b) the Person formed by or surviving any such

consolidation or merger (if other than the Issuer) or to which such sale, assignment, transfer, lease, conveyance or other disposition

shall have been made (the “Successor Company”) is an entity organized or existing under the laws of the United States, any

state thereof or the District of Columbia;

(2)

the Successor Company assumes all the obligations of the Issuer under the notes and the Indenture pursuant to agreements reasonably

satisfactory to the Trustee;

(3)

immediately after such transaction no Default or Event of Default exists; and

(4)

the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation,

merger or transfer and, if a supplemental Indenture is required, such supplemental Indenture complies with the Indenture and all conditions

Section 10.02.

Rights and Duties of Successor Company. In case of any consolidation,

merger or disposition respecting the Issuer in accordance with the foregoing, the Successor Company shall succeed to and be substituted

for the Issuer, with the same effect as if it had been named herein as the party of the first part, and the Issuer shall be relieved of

any further obligation under the Indenture and the Debt Securities. The Successor Company thereupon may cause to be signed, and may issue

either in its own name or in the name of the Issuer, any or all the Debt Securities issuable hereunder which theretofore shall not have

been signed by the Issuer and delivered to the Trustee; and, upon the order of the Successor Company, instead of the Issuer, and subject

to all the terms, conditions and limitations in the Indenture prescribed, the Trustee shall authenticate and shall deliver any Debt Securities

which previously shall have been signed and delivered by the officers of the Issuer or Plains All American GP, as the case may be, to

the Trustee for authentication, and any Debt Securities which the Successor Company thereafter shall cause to be signed and delivered

to the Trustee for that purpose. All the Debt Securities so issued shall in all respects have the same legal rank and benefit under the

Indenture as the Debt Securities theretofore or thereafter issued in accordance with the terms of the Indenture as though all such Debt

Securities had been issued at the date of the execution hereof.

In case of any such consolidation,

merger or disposition such changes in phraseology and form (but not in substance) may be made in the Debt Securities appertaining thereto

thereafter to be issued as may be appropriate.

for, the Issuer’s obligations under Section 7.06, and the Trustee’s and each paying agent’s obligations under the

last paragraph of this Section 11.01 and Section 11.02) and the Trustee, on demand and at the expense of the Issuer, shall execute

(C)

are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption

by the Trustee in the name, and at the expense, of the Issuer, and the Issuer, in the case of clause (A), (B) or (C) above, has irrevocably

deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust for such purpose cash in Dollars or U.S. Government

Obligations, or a combination thereof, in an amount sufficient (without consideration of any reinvestment of interest and as certified

by an independent public accountant designated by the Partnership expressed in a written certification thereof delivered to the Trustee)

to pay and discharge the entire indebtedness of such Debt Securities not theretofore delivered to the Trustee for cancellation, for principal

(and premium, if any) and accrued and unpaid interest to the date of such deposit (in the case of Debt Securities which have become due

and payable) or the Stated Maturity or redemption date, as the case may be;

(b)

the Issuer has paid or caused to be paid all other sums then due and payable hereunder by them under the Indenture; and

(c)

the Partnership has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions

precedent herein provided for relating to the satisfaction and discharge of the Indenture have been complied with.

In order to have money available

on a payment date to pay principal (and premium, if any, on) and interest on the Notes, the U.S. Government Obligations shall be payable

as to principal (and premium, if any) or interest at least one Business Day before such payment date in such amounts as shall provide

the necessary money.

The Trustee shall hold in

trust money or U.S. Government Obligations deposited with it pursuant to this Article XI. It shall apply the deposited money and

the money from U.S. Government Obligations through any paying agent and in accordance with the Indenture to the payment of principal of,

principal, premium or interest that remains unclaimed for two years, and, thereafter, Holders entitled to such money must look to the

Issuer for payment as general creditors.

Section 11.03.

Indemnity for U.S. Government Obligations. The Issuer shall

pay and shall indemnify the Trustee and the Holders against any tax, fee or other charge imposed on or assessed against deposited U.S.

Reinstatement. If the Trustee or any paying agent is unable

to apply any money or U.S. Government Obligations in accordance with this Article XI by reason of any legal proceeding or by reason

of any order or judgment of any court or government authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s

obligations under the Indenture and the Debt Securities of the defeased series shall be revived and reinstated as though no deposit had

occurred pursuant to this Article XI until such time as the Trustee or any paying agent is permitted to apply all such money or U.S.

Government Obligations in accordance with this Article XI.

Article XII

Miscellaneous

Provisions

Section 12.01.

Failure to mail a notice or

communication to a Holder or any defect in it or any defect in any notice by publication as to a Holder shall not affect the sufficiency

upon Application or Demand by the Issuer. Upon any application or demand by the Issuer to the Trustee to take any action under

any of the provisions of the Indenture, the Issuer shall furnish to the Trustee an Officers’ Certificate stating that all conditions

precedent provided for in the Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that,

in the opinion of such counsel, all such conditions precedent have been complied with, except that in the case of any such application

repayment of any Debt Security or the making of any sinking fund payment shall not be a business day at any Place of Payment for the Debt

Securities of such series, then payment of interest or principal and premium, if any, or the making of such sinking fund payment need

not be made on such date at such Place of Payment, but may be made on the next succeeding business day at such Place of Payment with the

same force and effect as if made on the date of maturity or the date fixed for redemption, and no interest shall accrue for the period

after such date. If a record date is not a business day, the record date shall not be affected.

Section 12.07.

Provisions Required by Trust Indenture Act to Control. If

and to the extent that any provision of the Indenture limits, qualifies or conflicts with another provision included in the Indenture

provision shall control.

Section 12.08.

Article XIII

Subordination

of Debt Securities

Section 13.01.

Applicability of Article; Agreement to Subordinate. The

provisions of this Article XII shall be applicable to the Debt Securities of any series (Debt Securities of such series being referred

to in this Article XIII as “Subordinated Debt Securities”) except to the extent such provisions may be changed or added

to pursuant to Section 2.03. Each Holder by accepting a Subordinated Debt Security agrees that the indebtedness evidenced by such

Subordinated Debt Security is subordinated in right of payment, to the extent and in the manner provided in this Article XIII, to

the prior payment of all Senior Indebtedness and that the subordination is for the benefit of and enforceable by the holders of Senior

Indebtedness. All provisions of this Article XIII shall be subject to Section 13.12.

Section 13.02.

Liquidation, Dissolution, Bankruptcy. Upon any payment or

distribution of the assets of the Issuer to creditors upon a voluntary or involuntary liquidation or a dissolution of the Issuer or in

a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Issuer or its property:

(1)

holders of Senior Indebtedness shall be entitled to receive payment in full in cash of the Senior Indebtedness (including interest

(if any), accruing on or after the commencement of a proceeding in bankruptcy, whether or not allowed as a claim against the Issuer in

such bankruptcy proceeding) before Holders of Subordinated Debt Securities shall be entitled to receive any payment of principal of, or

premium, if any, or interest on, the Subordinated Debt Securities; and

(2)

until the Senior Indebtedness is paid in full, any distribution to which Holders of Subordinated Debt Securities would be entitled

but for this Article XIII shall be made to holders of Senior Indebtedness as their interests may appear, except that such Holders

may receive Equity Interests and any debt securities that are subordinated to Senior Indebtedness to at least the same extent as the Subordinated

Debt Securities.

Section 13.03.

Default on Senior Indebtedness. The Issuer may not pay the

principal of, or premium, if any, or interest on, the Subordinated Debt Securities or make any deposit into a defeasance trust or pursuant

to Article XI and may not repurchase, redeem or otherwise retire (except, in the case of Subordinated Debt Securities that provide

for a mandatory sinking fund pursuant to Section 3.04, by the delivery of Subordinated Debt Securities by the Issuer to the Trustee

pursuant to the first paragraph of Section 3.05) any Debt Securities (collectively, “pay the Subordinated Debt Securities”)

if (i) any principal, premium, interest or any other amount payable in respect of Senior Indebtedness is not paid within any applicable

grace period (including at maturity) or (ii) any other default on Senior Indebtedness occurs and the maturity of such Senior Indebtedness

is accelerated in accordance with its terms unless, in either case, (x) the default has been cured or waived and any such acceleration

has been rescinded or (y) such Senior Indebtedness has been paid in full in cash; provided, however, that the Issuer

may pay the Subordinated Debt Securities without regard to the foregoing if the Issuer and the Trustee receive written notice approving

such payment from the Representative of each issue of Designated Senior Indebtedness. During the continuance of any default (other than

a default described in clause (i) or (ii) of the preceding sentence) with respect to any Senior Indebtedness pursuant to which the

maturity thereof may 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 Issuer may not pay the Subordinated Debt Securities for a period (a “Payment

Blockage Period”) commencing upon the receipt by the Issuer and the Trustee of written notice of such default from the Representative

of any Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period (a “Blockage Notice”) and

ending 179 days thereafter (or earlier if such Payment Blockage Period is terminated (i) by written notice to the Trustee and the

Issuer from the Person or Persons who gave such Blockage Notice, (ii) by repayment in full in cash of such Designated Senior Indebtedness

or (iii) because the default giving rise to such Blockage Notice 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 Section 13.03), unless

the holders of such Designated Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of such Designated

Senior Indebtedness, the Issuer may resume payments on the Subordinated Debt Securities after such Payment Blockage Period. Not more than

one Blockage Notice may be given in any consecutive 360- day period, irrespective of the number of defaults with respect to any number

of issues of Senior Indebtedness during such period. For purposes of this Section 13.03, no default or event of default which existed

or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Senior Indebtedness 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 Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such default or event of default shall have

been cured or waived for a period of not less than 90 consecutive days.

Section 13.04.

Acceleration of Payment of Debt Securities. If payment of

the Subordinated Debt Securities is accelerated because of an Event of Default, the Issuer or the Trustee shall promptly notify the holders

of the Designated Senior Indebtedness (or their Representatives) of the acceleration.

Section 13.05.

When Distribution Must Be Paid Over. If a distribution is

made to Holders of Subordinated Debt Securities that because of this Article XIII should not have been made to them, the Holders

who receive such distribution shall hold it in trust for holders of Senior Indebtedness and pay it over to them as their interests may

appear.

Section 13.06.

Subrogation. After all Senior Indebtedness is paid in full

and until the Subordinated Debt Securities are paid in full, Holders thereof shall be subrogated to the rights of holders of Senior Indebtedness

to receive distributions applicable to Senior Indebtedness. A distribution made under this Article XIII to holders of Senior Indebtedness

which otherwise would have been made to Holders of Subordinated Debt Securities is not, as between the Issuer and such Holders, a payment

by the Issuer on Senior Indebtedness.

Section 13.07.

Relative Rights. This Article XIII defines the relative

rights of Holders of Subordinated Debt Securities and holders of Senior Indebtedness. Nothing in the Indenture shall:

(1)

impair, as between the Issuer and Holders of Subordinated Debt Securities, the obligation of the Issuer, which is absolute and

unconditional, to pay principal of, and premium, if any, and interest on, the Subordinated Debt Securities in accordance with their terms;

(2)

prevent the Trustee or any Holder of Subordinated Debt Securities from exercising its available remedies upon an Event of Default,

subject to the rights of holders of Senior Indebtedness to receive distributions otherwise payable to Holders of Subordinated Debt Securities.

Section 13.08.

Subordination May Not Be Impaired by Issuer. No right of

any holder of Senior Indebtedness to enforce the subordination of the indebtedness evidenced by the Subordinated Debt Securities shall

be impaired by any act or failure to act by the Issuer or by their failure to comply with the Indenture.

Section 13.09.

Rights of Trustee and Paying Agent. Notwithstanding Section 13.03,

the Trustee or any paying agent may continue to make payments on Subordinated Debt Securities and shall not be charged with knowledge

of the existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date

of such payment, a Responsible Officer of the Trustee receives notice satisfactory to it that payments may not be made under this Article XIII.

The Issuer, the Registrar, any paying agent, a Representative or a holder of Senior Indebtedness may give the notice; provided,

however, that, if an issue of Senior Indebtedness has a Representative, only the Representative may give the notice.

The Trustee in its individual

or any other capacity may hold Senior Indebtedness with the same rights it would have if it were not Trustee. The Registrar and any paying

agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article XIII with respect

to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness; and nothing

in Article VII shall deprive the Trustee of any of its rights as such holder. Nothing in this Article XIII shall apply to claims

of, or payments to, the Trustee under or pursuant to Section 7.06.

Section 13.10.

Distribution or Notice to Representative. Whenever a distribution

is to be made or a notice given to holders of Senior Indebtedness, the distribution may be made and the notice given to their Representative

(if any).

Section 13.11.

Article XIII Not to Prevent Defaults or Limit Right to Accelerate.

The failure to make a payment pursuant to the Debt Securities by reason of any provision in this Article XIII shall not be construed

as preventing the occurrence of a Default. Nothing in this Article XIII shall have any effect on the right of the Holders or the

Trustee to accelerate the maturity of the Subordinated Debt Securities.

Section 13.12.

Trust Moneys Not Subordinated. Notwithstanding anything

contained herein to the contrary, payments from money or the proceeds of U.S. Government Obligations held in a defeasance trust or in

trust under Article XI by the Trustee for the payment of principal of, and premium, if any, and interest on, the Subordinated Debt

Securities shall not be subordinated to the prior payment of any Senior Indebtedness or subject to the restrictions set forth in this

Article XIII, and none of the Holders thereof shall be obligated to pay over any such amount to the Issuer or any holder of Senior

Indebtedness or any other creditor of the Issuer.

Section 13.13.

Trustee Entitled to Rely. Upon any payment or distribution

pursuant to this Article XIII, the Trustee and the Holders shall be entitled to rely (i) upon any order or decree of a court

of competent jurisdiction in which any proceedings of the nature referred to in Section 13.02 are pending, (ii) upon a certificate

of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to such Holders or (iii) upon

the Representatives for the holders of Senior Indebtedness for the purpose of ascertaining the Persons entitled to participate in such

payment or distribution, the holders of the Senior Indebtedness and other indebtedness of the Issuer, the amount thereof or payable thereon,

the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XIII. In the event that

the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness

to participate in any payment or distribution pursuant to this Article XIII, the Trustee may request such Person to furnish evidence

to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person

is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article XIII,

and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right

of such Person to receive such payment. The provisions of Sections 7.01 and 7.02 shall be applicable to all actions or omissions

of actions by the Trustee pursuant to this Article XIII.

Section 13.14.

Trustee to Effectuate Subordination. Each Holder by accepting

a Subordinated Debt Security authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to

acknowledge or effectuate the subordination between the Holders of Subordinated Debt Securities and the holders of Senior Indebtedness

as provided in this Article XIII and appoints the Trustee as attorney-in-fact for any and all such purposes.

Section 13.15.

Trustee Not Fiduciary for Holders of Senior Indebtedness.

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders

if it shall mistakenly pay over or distribute to Holders of Subordinated Debt Securities or the Issuer or any other Person, money or assets

to which any holders of Senior Indebtedness shall be entitled by virtue of this Article XIII or otherwise.

Section 13.16.

Reliance by Holders of Senior Indebtedness on Subordination Provisions.

Each Holder by accepting a Subordinated Debt Security acknowledges and agrees that the foregoing subordination provisions are, and are

intended to be, an inducement and a consideration to each holder of any Senior Indebtedness, whether such Senior Indebtedness was created

or acquired before or after the issuance of the Subordinated Debt Securities, to acquire and continue to hold, or to continue to hold,

such Senior Indebtedness and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions

in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness.

The Trustee hereby accepts

the trusts in the Indenture upon the terms and conditions herein set forth.

IN WITNESS WHEREOF, the parties

hereto have caused the Indenture to be duly signed as of the date first written above.

WHEREAS, the Original Indenture,

to authorize the execution and delivery of this Supplemental Indenture and to make it a valid and binding obligation of the Issuer have

been done or performed.

NOW, THEREFORE, in consideration

of the agreements and obligations set forth herein and for other good and valuable consideration, the sufficiency of which is hereby acknowledged,

the parties hereto hereby agree as follows:

ARTICLE I

Section 1.01.

Establishment.  There is hereby established

of this Supplemental Indenture, the provisions of this Supplemental Indenture shall govern.

(e)

The modifications to the Original Indenture made by this Supplemental Indenture shall apply only with respect to the Notes, and

not with respect to other series of Debt Securities that may be issued under the Original Indenture.

of a partnership or limited liability company, partnership or membership interests (whether general or limited); and (iv) any other interest

than five Business Days appear, such number of Business Days appearing) under the caption “Treasury Constant Maturities” in

the most recent H.15 (as defined herein) as of 5:00 p.m. (Eastern Time); or (ii) if there are no such published yields on actively traded

U.S. treasury securities adjusted to constant maturity, for five-year maturities, then the rate will be determined by interpolation between

the average of the yields on actively traded U.S. treasury securities adjusted to constant maturity for two series of actively traded

U.S. treasury securities, (A) one maturing as close as possible to, but earlier than, the Reset Date following the next succeeding Reset

Interest Determination Date and (B) the other maturing as close as possible to, but later than, the Reset Date following the next succeeding

Reset Interest Determination Date, in each case for the five Business Days appearing (or, if fewer than five Business Days appear, such

meaning assigned to it in Section 1.01(a) hereof, and includes both the Notes issued on the Issue Date and any Additional Notes issued

thereafter.

“Rating Agency Event”

means, as of any date, a change, clarification or amendment in the methodology published by any nationally recognized statistical rating

organization within the meaning of Section 3(a)(62) of the Exchange Act (or any successor provision thereto), that then publishes a rating

for the Partnership (together with any successor thereto, a “rating agency”) in assigning equity credit to securities such

as the Notes, (a) as such methodology was in effect on September 9, 2026, in the case of any rating agency that published a rating for

the Issuer as of September 9, 2026, or (b) as such methodology was in effect on the date such rating agency first published a rating for

the Issuer, in the case of any rating agency that first publishes a rating for the Issuer after September 9, 2026 (in the case of either

clause (a) or (b), the “current methodology”), that results in (i) any shortening of the length of time for which a particular

level of equity credit pertaining to the Notes by such rating agency would have been in effect had the current methodology not been changed

or (ii) a lower equity credit (including up to a lesser amount) being assigned by such rating agency to the Notes as of the date of such

change, clarification or amendment than the equity credit that would have been assigned to the Notes by such rating agency had the current

Reset Date applicable to the Notes and thereafter each period from and including a Reset Date to, but excluding, the next following Reset

Date.

“Senior Indebtedness”

means, with respect to the Notes, (i) indebtedness of the Issuer, whether outstanding at the date of the Indenture or incurred, created

or assumed after such date, (a) in respect of money borrowed by the Issuer (including any financial derivative, hedging or futures contract

or similar instrument, to the extent any such item is primarily a financing transaction) and (b) evidenced by debentures, bonds, notes,

credit or loan agreements or other similar instruments or agreements issued or entered into by the Issuer; (ii) all synthetic lease obligations,

capitalized lease obligations and finance lease obligations of the Issuer; (iii) all obligations of the Issuer issued or assumed as the

deferred purchase price of property, all conditional sale obligations of the Issuer and all obligations of the Issuer under any title

retention agreement (but excluding trade accounts payable arising in the ordinary course of business and long-term purchase obligations);

(iv) all obligations of the Issuer for the reimbursement of any letter of credit, banker’s acceptance, security purchase facility

or similar credit transaction; and (v) all obligations of the type referred to in clauses (i) through (iv) above of other persons for

the payment of which the Issuer is responsible or liable as obligor, guarantor or otherwise, except for any obligations, instruments or

agreements of the type referred to in any of clauses (i) through (v) above that, by the terms of the instruments or agreements creating

or evidencing the same or pursuant to which the same is outstanding, are subordinated or equal in right of payment to the Notes.

“Tax Event” means

that the Partnership has received an opinion of counsel experienced in such matters to the effect that, as a result of:

(a)

any amendment to, clarification of, or change, including any announced prospective change, in the laws or treaties of the United

States or any of its political subdivisions or taxing authorities, or any regulations under those laws or treaties;

(b)

an administrative action, which means any judicial decision or any official administrative pronouncement, ruling, regulatory procedure,

notice or announcement, including any notice or announcement of intent to issue or adopt any administrative pronouncement, ruling, regulatory

procedure or regulation;

(c)

any amendment to, clarification of, or change in the official position or the interpretation of any administrative action or judicial

decision or any interpretation or pronouncement that provides for a position with respect to an administrative action or judicial decision

that differs from the previously generally accepted position, in each case by any legislative body, court, governmental authority or regulatory

body, regardless of the time or manner in which that amendment, clarification or change is introduced or made known; or

(d)

a threatened challenge asserted in writing in connection with a tax audit of the Partnership or any of its Subsidiaries, or a publicly-known

threatened challenge asserted in writing against any other taxpayer that has raised capital through the issuance of securities that are

substantially similar to the Notes,

which amendment, clarification

or change is effective or the administrative action is taken or judicial decision, interpretation or pronouncement is issued or threatened

challenge is asserted or becomes publicly-known after September 9, 2026, there is more than an insubstantial risk that interest payable

by the Partnership on such Notes is not deductible, or within 90 days would not be deductible, in whole or in part, by the Partnership

for U.S. federal income tax purposes.

ARTICLE III

THE NOTES

Section 3.01.

Form; General. The Notes shall be issued initially

in the form of one or more Global Securities. The Notes and Trustee’s certificate of authentication shall be substantially in the

form of Exhibit A hereto, the terms of which are incorporated in and made a part of this Supplemental Indenture, and the Issuer and the

Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to such terms and provisions and to be bound

thereby. The Notes are issuable only in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000

in excess thereof.

Section 3.02.

Title, Amount and Payment of Principal and Interest.

(a)

The Notes shall be entitled the “Series A Junior Subordinated Notes due 2056.” The Trustee shall authenticate

and deliver the Notes for original issue on the date hereof (the “Original Notes”) in the aggregate principal

amount of $700,000,000. The aggregate principal amount of Notes that may be outstanding at any time may not exceed $700,000,000 plus such

additional principal amounts as may be issued and authenticated pursuant to Section 3.07.

(b)

The Notes shall bear interest (i) from and including the Issue Date to, but excluding, the First Reset Date at the rate of

6.750% per annum and (ii) from and including the First Reset Date, during each Reset Period at a rate per annum equal to the Five-year

U.S. Treasury Rate as of the most recent Reset Interest Determination Date plus a spread of 2.141 percentage points, to be reset on each

Reset Date; provided, that the interest rate on the Notes during any Reset Period will not reset below 6.750%. The applicable interest

rate for each Reset Period will be determined by the Calculation Agent in accordance with this Section 3.02 and Section 3.06. The Notes

shall have a Stated Maturity of December 15, 2056 (the “Maturity Date”). Interest accumulating or payable

on the Notes for any Interest Payment Period (or portion thereof) will be calculated on the basis of a 360-day year of twelve 30-day months.

Interest on the Notes shall be payable semi-annually in arrears on each June 15 and December 15 (each, an “Interest Payment

Date”) of each year, beginning on June 15, 2027, to Holders of record at the close of business on the immediately preceding

Regular Record Date, subject to Section 3.04 hereof. If an Interest Payment Date is not a Business Day, payment of interest will

be made on the next succeeding Business Day, without any interest, additional interest, or other payment in lieu of interest or additional

interest accumulating with respect to this delay. The Partnership will give written notice of the relevant Five-year U.S. Treasury Rate

as soon as reasonably practicable following each Reset Interest Determination Date to the Trustee and paying agent.

(c)

If the Partnership, in its sole discretion, determines that the Five-year U.S. Treasury Rate cannot be determined pursuant

to the methods set forth herein, the Partnership may, in its sole discretion, designate an unaffiliated agent or advisor, which may include

an unaffiliated underwriter for the offering of the Notes or any affiliate of any such underwriter, but shall not include the Trustee

(the “Designee”), to determine whether there is an industry-accepted successor rate to the Five-year U.S. Treasury

Rate. If the Designee determines that there is such an industry-accepted successor rate, then the Five-year U.S. Treasury Rate shall be

such successor rate and, in that case, the Designee may adjust the spread and may determine and adjust the Business Day convention, the

definition of a “Business Day” and the Reset Interest Determination Date to be used and any other relevant methodology

for determining or otherwise calculating such successor rate, including any adjustment factor needed to make such successor rate comparable

to the Five-year U.S. Treasury Rate in each case, in a manner that is consistent with industry-accepted practices for the use of such

successor rate. If the Partnership, in its sole discretion, does not designate a Designee or if the Designee determines that there is

no industry-accepted successor rate, then the Five-year U.S. Treasury Rate will be the same rate determined for the prior Reset Interest

Determination Date or, if this sentence is applicable with respect to the first Reset Interest Determination Date, the applicable interest

rate for the First Reset Period (as defined below) will be 6.750%.

(d)

In no event shall the Trustee be responsible for determining whether there is an industry-accepted successor rate to the

Five-year U.S. Treasury Rate or for making any adjustments to any spread thereon or the Business Day convention or interest determination

dates with respect thereto or any other relevant methodology for calculating any such successor rate, including any adjustment factor

needed to make such successor rate comparable to the Five-year U.S. Treasury Rate in each case, in a manner that is consistent with industry-accepted

practices for the use of such successor rate. In connection with the foregoing, the Trustee shall be entitled to conclusively rely on

any determination made by the Partnership or its Designee and will have no liability for such actions taken at the Partnership’s

or Designee’s direction or otherwise in connection with respect to any such determination by the Partnership or its Designee.

Section 3.03.

Regular Record Date. With respect to each Interest

Payment Date, the record date for the Notes shall be June 1 and December 1 (whether or not a Business Day), as the case may be, next preceding

such Interest Payment Date (each, a “Regular Record Date”).

Section 3.04.

Deferral of Interest.

(a)

So long as no Event of Default with respect to the Notes has occurred and is continuing, the Partnership may, at its option, defer

interest payments on the Notes, from time to time, for one or more deferral periods of up to 20 consecutive Interest Payment Periods (each

such deferral period, commencing on the Interest Payment Date on which the first such deferred interest payment otherwise would have been

made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the Maturity Date

or end on a day other than the day immediately preceding an Interest Payment Date. During any Optional Deferral Period, interest on the

Notes will continue to accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring

during such Optional Deferral Period in accordance with the terms of the Notes). In addition, during any Optional Deferral Period, interest

on the deferred interest (“compound interest”) will accrue at the then-applicable interest rate on the Notes (as reset

from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes), compounded

semi-annually, to the extent permitted by applicable law.

(b)

No interest will be due or payable on the Notes during an Optional Deferral Period, except upon a redemption of any Notes on any

Redemption Date during such Optional Deferral Period (in which case, all accrued and unpaid interest (including, to the extent permitted

by applicable law, any compound interest) on the Notes to be redeemed to, but excluding, such Redemption Date will be due and payable

on such Redemption Date), or unless the principal of and interest on the Notes shall have been declared due and payable as the result

of an Event of Default with respect to the Notes (in which case, all accrued and unpaid interest, including, to the extent permitted by

applicable law, any compound interest, on the Notes, shall become due and payable). All references in the Notes and, insofar as relates

to the Notes, the Indenture to “interest” on the Notes shall be deemed to include any such deferred interest and, to the extent

permitted by applicable law, any compound interest, unless otherwise expressly stated or the context otherwise requires.

(c)

Before the end of any Optional Deferral Period that is shorter than 20 consecutive Interest Payment Periods, the Partnership may

elect, at its option, to extend such Optional Deferral Period, so long as the entire Optional Deferral Period does not exceed 20 consecutive

Interest Payment Periods or extend beyond the Maturity Date. The Partnership may also elect, at its option, to shorten the length of any

Optional Deferral Period. No Optional Deferral Period (including as extended or shortened) may end on a day other than the day immediately

preceding an Interest Payment Date. At the end of any Optional Deferral Period, if all amounts then due on the Notes, including all accrued

and unpaid interest thereon (including, without limitation and to the extent permitted by applicable law, any compound interest), are

paid, the Partnership may elect to begin a new Optional Deferral Period; provided, however, that, without limitation of the foregoing,

the Partnership may not begin a new Optional Deferral Period unless the Partnership has paid all accrued and unpaid interest on the Notes

(including, without limitation and to the extent permitted by applicable law, any compound interest) from any previous Optional Deferral

Periods.

(d)

During any Optional Deferral Period, the Partnership (and its Subsidiaries, as applicable) shall not do any of the following (subject

to the exceptions set forth in clause (e) of this Section 3.04):

(i)

declare or pay any dividends or distributions on any Capital Stock of the Partnership;

(ii)

redeem, purchase, acquire or make a liquidation payment with respect to any Capital Stock of the Partnership;

(iii)

pay any principal, interest or premium on, or repay, repurchase or redeem, any indebtedness of the Partnership that ranks equally

with or junior to the Notes in right of payment; or

(iv)

make any payments with respect to any guarantees by the Partnership of any indebtedness if such guarantees rank equally with or

junior to the Notes in right of payment.

(e)

However, during an Optional Deferral Period, the Partnership may (i) declare and pay dividends or distributions payable solely

in its common units (together with cash in lieu of any fractional unit) or options, warrants or rights to subscribe for or purchase units

of its common units, (ii) declare and pay any dividend or distribution in connection with the implementation of a plan (a “Rights

Plan”) providing for the issuance by the Partnership to all holders of its common units of rights entitling them to subscribe

for or purchase its common units or any class or series of its preferred equity, which rights (1) are deemed to be transferred with such

common units, (2) are not exercisable until the occurrence of a specified event or events and (3) are also issued in respect of future

issuances of its common units, (iii) issue any of shares of its Capital Stock under any Rights Plan or redeem or repurchase any rights

distributed pursuant to a Rights Plan, (iv) reclassify its Capital Stock or exchange or convert one class or series of its Capital Stock

for another class or series of its Capital Stock, (v) purchase fractional interests in shares of its Capital Stock pursuant to the conversion

or exchange provisions of such Capital Stock or the security being converted or exchanged, and (vi) purchase, acquire or withhold its

common units related to the issuance of its common units or rights under any dividend reinvestment plan or related to any of its benefit

plans for its directors, officers, employees, consultants or advisors, including any employment contract.

(f)

The Partnership will give the Holders of the Notes and the Trustee written notice of its election of, or any shortening or extension

of, an Optional Deferral Period at least 10 Business Days prior to the earlier of (i) the next succeeding Interest Payment Date or (ii)

the date upon which the Partnership is required to give notice to any applicable self-regulatory organization or to Holders of the Notes

of the next succeeding Interest Payment Date or the record date therefor. The record date for the payment of deferred interest and, to

the extent permitted by applicable law, any compound interest payable on the Interest Payment Date immediately following the last day

of an Optional Deferral Period will be the Regular Record Date with respect to such Interest Payment Date.

Section 3.05.

Interest Payments and Redemption. Notwithstanding

any provision of this Article III, installments of interest on the Notes that are due and payable on any Interest Payment Date falling

on or prior to a Redemption Date will be payable on that Interest Payment Date to the registered Holders thereof as of the close of business

on the relevant Regular Record Date according to the terms of the Notes and the Indenture, except that, if the Redemption Date for any

Notes falls on any day during an Optional Deferral Period, accrued and unpaid interest (including, to the extent permitted by applicable

law, any compound interest) on such Notes will be paid on such Redemption Date to the Persons entitled to receive the redemption price

of such Notes. The Interest Payment Date falling immediately after the last day of an Optional Deferral Period shall not be deemed to

fall on a day during such Optional Deferral Period.

Section 3.06.

Calculation Agent.

(a)

Unless the Partnership has validly called all of the outstanding Notes for redemption during the First Reset Period, the Partnership

will appoint a calculation agent (the “Calculation Agent”) for the Notes prior to the Reset Interest Determination

Date immediately preceding the First Reset Date; provided that, if the Partnership has called all of the outstanding Notes for

redemption on a Redemption Date occurring during the First Reset Period, but the Partnership does not redeem all of the outstanding Notes

on such Redemption Date, the Partnership will appoint a Calculation Agent for the Notes prior to the Reset Interest Determination Date

preceding the First Reset Date. The Partnership may terminate any such appointment and may appoint a successor Calculation Agent at any

time and from time to time (so long as there shall always be a Calculation Agent in respect of the Notes when so required). The Partnership

may appoint itself or an affiliate of the Partnership as Calculation Agent.

(b)

The applicable interest rate for each Reset Period will be determined by the Calculation Agent as of the applicable Reset Interest

Determination Date. Promptly upon such determination, the Calculation Agent will notify the Partnership of the interest rate for the Reset

Period and the Partnership will promptly notify, or cause the Calculation Agent to promptly notify, the Trustee and paying agent for the

Notes in writing of such interest rate, upon which the Trustee and paying agent will be permitted to conclusively rely. The Calculation

Agent’s determination of any interest rate, and its calculation of the amount of interest for any Interest Payment Period beginning

on or after the First Reset Date, will be on file at the Partnership’s principal offices, will be made available to any Holder or

beneficial owner of the Notes upon request and will be final and binding in the absence of manifest error.

Section 3.07.

Issuance of Additional Notes. The Issuer may,

from time to time, issue an unlimited amount of additional Notes (“Additional Notes”) under the Indenture, which shall

be issued in the same form as the Original Notes and which shall have identical terms as the Original Notes other than the offering price,

the date of issuance and, if applicable, the date from which interest thereon shall begin to accrue and the first Interest Payment Date,

and except that the provisions of the Notes specifying the rate of interest thereon to but excluding the applicable First Reset Date shall

not be applicable to any such additional Notes whose date of original issuance is on or after the applicable First Reset Date. If any

such Additional Notes are not fungible with the Original Notes for U.S. federal income tax purposes, they will have a different CUSIP,

ISIN, or other identifying number so that they are distinguishable from the Original Notes. The Original Notes and any Additional Notes

subsequently issued shall be treated as a single series for all purposes under the Indenture, including waivers, amendments, redemptions

and offers to purchase.

Section 3.08.

Global Security Legend. Each of the Global Securities

shall bear a legend in substantially the following form:

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE

OF THE DEPOSITORY TRUST COMPANY (“DTC”) (55 WATER STREET, NEW YORK, NEW YORK 10041) TO THE PARTNERSHIP OR ITS AGENT

FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER

NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY

BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON

IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY

SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE

AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN

THE INDENTURE REFERRED TO HEREIN.

ARTICLE IV

REDEMPTION

Section 4.01.

Optional Redemption.

The Partnership may at its

option redeem the Notes, in whole or from time to time in part, (i) on any day in the period commencing on the date falling 90 days prior

to the First Reset Date and ending on (and including) the First Reset Date (the “First Reset Period”) and (ii) after the First

Reset Date, on any applicable Interest Payment Date, in each case at a redemption price in cash equal to 100% of the principal amount

of the Notes to be redeemed, plus, subject to Section 3.05, accrued and unpaid interest on the Notes to be redeemed to, but excluding,

the redemption date.

Section 4.02.

Redemption Following a Tax Event.

The Partnership may at its

option redeem the Notes, in whole but not in part, at any time within 120 days after a Tax Event at a redemption price in cash equal to

100% of the principal amount of the Notes, plus, subject to Section 3.05, accrued and unpaid interest on the Notes

to, but excluding, the Redemption Date.

Section 4.03.

Redemption Following a Rating Agency Event.

The Partnership may at its

option redeem the Notes, in whole but not in part, at any time during the continuance of and, in any event, within 120 days after the

occurrence of, a Rating Agency Event at a redemption price in cash equal to 102% of the principal amount of the Notes, plus, subject to

Section 3.05, accrued and unpaid interest on the Notes to, but excluding, the Redemption Date.

Section 4.04.

Notices of Redemption.

The following provisions shall

apply with respect to redemptions of the Notes notwithstanding any contrary or inconsistent provisions of Section 3.02 of the Original

Indenture:

(a) Notice of redemption shall be given

by first-class mail, postage prepaid, or otherwise sent (or when the Notes are in the form of Global Securities, sent pursuant to the

applicable procedures of the Depositary) not less than 10 nor more than 60 days prior to the redemption date, to each Holder of Notes

to be redeemed, at the address of such Holder appearing in the register of Notes maintained by the Registrar, except that redemption notices

may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance or a satisfaction or

discharge of the Indenture with respect to the Notes.

Once notice of redemption is delivered,

the Notes called for redemption will become due and payable on the redemption date at the applicable redemption price, plus, subject to

Section 3.05, accrued and unpaid interest to, but excluding, the redemption date, and will be paid upon surrender thereof for redemption,

unless (a) the notice of redemption provides that such redemption shall be subject to the condition described in the next succeeding paragraph

and (b) such redemption shall have been canceled in accordance with the provisions of the next succeeding paragraph because such condition

shall not have been satisfied. If only part of a Note is redeemed, the Trustee will issue in the name of the registered Holder of the

Note and deliver to such Holder a new Note in a principal amount equal to the unredeemed portion of the principal of the Note surrendered

for redemption. If the Issuer elects to redeem all or a portion of the Notes, then, unless otherwise provided in such notice of redemption

as described in the next succeeding paragraph, the redemption will not be conditional upon receipt by the paying agent or the Trustee

of monies sufficient to pay the redemption price.

If, at the time a notice of redemption

is given, (i) the Issuer has not effected satisfaction and discharge of the Notes pursuant to Article XI of the Original Indenture and

(ii) such notice of redemption is not being given in connection with or in order to effect satisfaction and discharge of the Notes, then,

if the notice of redemption so provides and at the Issuer’s option, the redemption may be subject to the condition that the Trustee

shall have received, on or before the applicable redemption date, monies in an amount sufficient to pay the redemption price and accrued

and unpaid interest on the Notes called for redemption to, but excluding, the redemption date. If monies in such amount are not received

by the Trustee on or before such redemption date, such notice of redemption shall be automatically canceled and of no force or effect,

such proposed redemption shall be automatically canceled and the Issuer shall not be required to redeem the Notes called for redemption

on such redemption date. In the event that a redemption is canceled, the Issuer will, not later than the Business Day immediately following

the proposed redemption date, deliver, or cause to be delivered, notice of such cancellation to the registered Holders of the Notes called

for redemption (which notice will also indicate that any Notes or portions thereof surrendered for redemption shall be returned to the

applicable Holders), and the Issuer will direct the Trustee to, and the Trustee will, promptly return any Notes or portions thereof that

have been surrendered for redemption to the applicable Holders. Unless the Issuer defaults in payment of the redemption price or the proposed

redemption is canceled in accordance with the provisions set forth above, on and after the redemption date interest will cease to accrue

on the Notes or portions thereof called for redemption.

If less than all of the Notes of a series

are redeemed at any time, the Trustee will select the Notes or any portions thereof in integral multiples of $1,000 to be redeemed on

a pro rata basis, by lot or by any other method the Trustee deems fair and appropriate and, when the Notes are in the form of Global Securities,

in accordance with the applicable procedures of the Depositary

Section 4.05.

No Sinking Fund; Mandatory Redemption.

The Partnership is not required

to make any mandatory redemption, mandatory repurchase or sinking fund payments with respect to the Notes or to repurchase the Notes at

the option of Holders. The Partnership may at any time and from time to time purchase Notes in the open market or otherwise.

ARTICLE

COVENANTS

Section

5.01.          Compliance Certificate.

(a)

The Issuer shall, so long as any of the Notes are outstanding, deliver to the Trustee, within 30 days after the occurrence of any

Default or Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’

Certificate specifying such Default or Event of Default, its status and what action the Issuer is taking or proposes to take with respect

thereto.

ARTICLE

DEFAULTS AND REMEDIES

Section

6.01.         Events of Default.

With respect to the Notes, the provisions of this Section 6.01 shall apply in lieu of the provisions of Section 6.01 of the Original Indenture

in their entirety.

(a)

An “Event of Default” occurs if:

(i)

The Issuer does not pay any interest on any Note when it becomes due and payable and such default continues for 30 days (regardless

of whether such payment is prohibited by Article VII), except as the result of a deferral of interest payments in accordance with Section

3.04;

(ii)

The Issuer does not pay any principal of or premium, if any, on any Note when it becomes due and payable (regardless of whether

such payment is prohibited by Article VII);

(iii)

The Issuer remains in breach of any other covenant (excluding covenants solely applicable to one or more other series of Debt Securities

issued under the Original Indenture) in the Indenture or the Notes for 90 days after there has been given to the Issuer, by registered

or certified mail, a written notice of default specifying such default or breach and requiring remedy of the default or breach; the notice

must be sent by either the Trustee or registered Holders of at least 33% of the principal amount of the outstanding Notes; or

(iv)

(1) pursuant to or within the meaning of Bankruptcy Law, the Issuer commences a voluntary case, consents to the entry of an order

for relief against it in an involuntary case, consents to the appointment of a custodian of it or for all or substantially all of its

property, makes a general assignment for the benefit of its creditors, or generally is not paying its debts as they become due, or (2)(x)

a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that is for relief against the Issuer in an involuntary

case, appoints a custodian of the Issuer, or orders the liquidation of the Issuer and (y) such order or decree remains unstayed and in

effect for 60 consecutive days.

However, as discussed below,

neither the Trustee nor the Holders of the Notes will be entitled to declare the Notes to be due and payable immediately upon the occurrence

of an Event of Default described in clause (iii) above.

No Event of Default with respect

to the Notes will necessarily constitute an Event of Default with respect to the Debt Securities of any other series issued under the

Original Indenture, and no Event of Default with respect to any such other series of Debt Securities issued under the Original Indenture

will necessarily constitute an Event of Default with respect to the Notes. If an Event of Default, other than an Event of Default described

in Section 6.01(a)(iii), occurs and is continuing with respect to the Notes, then either the Trustee or the registered Holders of not

less than 33% in principal amount of the outstanding Notes may declare the principal amount of all of the Notes, together with accrued

and unpaid interest thereon, if any, to be due and payable immediately, by a notice in writing to the Issuer (and to the Trustee if given

by the registered Holders), and upon any such declaration, such principal amount of all outstanding Notes and accrued and unpaid interest,

if any, thereon shall become immediately due and payable. If an Event of Default described in Section 6.01(a)(iv) occurs and is continuing

with respect to all series of subordinated Debt Securities issued under the Original Indenture at the time outstanding, then either the

Trustee or the registered Holders of not less than 33% in principal amount of all such outstanding subordinated Debt Securities under

the Original Indenture may declare the principal amount of all such outstanding subordinated Debt Securities, together with accrued and

unpaid interest thereon, to be due and payable immediately, and upon any such declaration, such principal amount of all outstanding Notes

and accrued and unpaid interest, if any, thereon shall become immediately due and payable.

However, if an Event of Default

described in Section 6.01(a)(iii) occurs and is continuing, neither the Trustee nor the registered Holders of the Notes will be entitled

to declare the principal of the Notes, or accrued or unpaid interest thereon, to be due and payable immediately, by reason of the occurrence

and continuation of such Event of Default. However, they may exercise the other rights and remedies available under the Indenture upon

the occurrence of an Event of Default. The Holders of a majority in principal amount of the Notes may, by written notice to the Trustee,

rescind any acceleration with respect to the Notes and annul its consequences if rescission would not conflict with any judgment or decree

of a court of competent jurisdiction and all existing Events of Default with respect to the Notes, other than the nonpayment of the principal

of, premium, if any, and interest on the Notes that have become due solely by such acceleration, have been cured or waived.

Section

6.02.          Control By Holders. The following provisions shall apply with respect to the Notes in lieu

of Section 6.06 of the Original Indenture:

The Holders of a majority

in principal amount of the outstanding Notes shall have the right to (i) direct the time, method and place of conducting any proceeding

for any remedy available to the Trustee, or (ii) exercising any trust or power conferred on the Trustee, with respect to the Notes; provided

that

(a)

such direction shall not be in conflict with any law or with this Indenture,

(b)

the Trustee may take any other action deemed proper by the Trustee which is consistent with such direction,

(c)

the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall, by a Responsible Officer

or Officers of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability, and

(d)

the Holders have offered to the Trustee security or indemnity satisfactory to it against any cost, liability, or expense.

If an Event of Default is continuing

with respect to all outstanding Debt Securities (that are subordinated pursuant to Article VII hereof or a similar subordination provision),

the Holders of a majority in principal amount of all such outstanding Debt Securities, considered as one class, shall have the right to

make such direction, and not the Holders of such Debt Securities of any one series.

ARTICLE

VII

SUBORDINATION

Section

7.01.        Subordination. The

Notes will be subordinated in right of payment to the prior payment in full of all Senior Indebtedness in accordance with Article XIII

of the Original Indenture, except that the following provisions of this Section 7.01 shall apply in lieu of Sections 13.02 and 13.03 of

the Original Indenture.

Upon:

(a)

any payment by, or distribution of the assets of, the Partnership upon its dissolution, winding-up, liquidation or reorganization,

whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings,

(b)

a failure to pay any interest, principal or other monetary amounts due on any of the Senior Indebtedness when due and continuance

of that default beyond any applicable grace period, or

(c)

acceleration of the maturity of any Senior Indebtedness as a result of a default,

the Holders of all Senior Indebtedness

will be entitled to receive, in the case of clause (a) immediately above, payment of all amounts due or to become due on all Senior Indebtedness,

or in the case of clauses (b) and (c) immediately above, payment of all amounts due on all Senior Indebtedness, before the Holders of

the Notes are entitled to receive any payment. So long as any of the events in clauses (a), (b), or (c) immediately above has occurred

and is continuing, any amounts payable or assets distributable on the Notes will instead be paid or distributed, as the case may be, directly

to the Holders of Senior Indebtedness to the extent necessary to pay, in the case of clause (a) immediately above, all amounts due or

to become due upon all such Senior Indebtedness, or, in the case of clauses (b) and (c) immediately above, all amounts due on all such

Senior Indebtedness, and, if any such payment or distribution is received by the Trustee under the Indenture or the Holders of any of

the Notes before all Senior Indebtedness due and to become due or due, as applicable, is paid, such payment or distribution must be paid

over to the Holders of the unpaid Senior Indebtedness. Subject to paying the Senior Indebtedness due and to become due in the case of

clause (a) immediately above or the Senior Indebtedness due in the case of clauses (b) and (c) immediately above, the Holders of the Notes

will be subrogated to the rights of the Holders of the Senior Indebtedness to receive payments applicable to the Senior Indebtedness until

the Notes are paid in full.

LEGAL DEFEASANCE

Section

8.01.         Option to Effect Legal Defeasance.

The Issuer may, as set forth in an Officers’ Certificate, at any time, elect to have Section 8.02 be applied to all outstanding

Notes upon compliance with the conditions set forth below in this Article VIII.

Section

8.02.         Legal Defeasance and Discharge.

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuer shall, subject

to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect

to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this

purpose, Legal Defeasance means that the Issuer shall be deemed to have paid and discharged the entire Debt represented by the outstanding

Notes, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 8.05 hereof and the other

Sections of the Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and the Indenture,

except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(a)

the rights of Holders of Outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as

more fully set forth in such Section, payments in respect of the principal of, premium on, if any, and interest on such Notes when such

payments are due,

(b)

the Issuer’s obligations with respect to such Notes under Sections 2.07, 2.08, 2.09 and 4.02 of the Original Indenture,

(c)

the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s obligations in connection therewith,

(d)

this Article VIII, and

(e)

the Issuer’s rights of redemption under Article IV hereof.

Section

8.03.          [Reserved].

Section

8.04.         Conditions to Legal Defeasance.

The following shall be the conditions to the application of Section 8.02 hereof to the Outstanding Notes:

In order to exercise Legal

Defeasance:

(a)

the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in Dollars, U.S.

Government Obligations, or a combination thereof, in such amounts as shall be sufficient, in the written opinion of a nationally recognized

firm of independent public accountants, to pay the principal of, premium on, if any, and interest on the Outstanding Notes at the Stated

Maturity thereof or on the applicable redemption date, as the case may be, and the Issuer must specify whether the Notes are being defeased

to maturity or to a particular redemption date;

(b)

the Issuer shall have delivered to the Trustee an Opinion of Counsel confirming that (i) the Issuer has received from, or

there has been published by, the Internal Revenue Service a ruling or (ii) since the date of the Indenture, there has been a change in

the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that,

the Holders of the Outstanding Notes shall not recognize income, gain or loss for federal income tax purposes as a result of such Legal

Defeasance and shall 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 Legal Defeasance had not occurred;

(c)

no Default or Event of Default shall have occurred and be continuing either on the date of such deposit (other than a Default

or Event of Default resulting from the incurrence of Debt all or a portion of the proceeds of which shall be applied to such deposit);

(d)

such Legal Defeasance shall not result in a breach or violation of, or constitute a default under, any agreement or instrument

(other than the Notes and the Indenture) to which the Partnership or any of its Subsidiaries is a party or by which the Partnership or

any of its Subsidiaries is bound;

(e)

the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit,

the trust funds shall not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting

creditors’ rights generally;

(f)

the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuer

with the intent of preferring the Holders over any other creditors of the Issuer or with the intent of defeating, hindering, delaying

or defrauding any other creditors of the Issuer; and

(g)

the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all

conditions precedent provided for or relating to the Legal Defeasance have been complied with.

Section

8.05.         Deposited Money and U.S. Government Obligations to be Held in Trust; Other Miscellaneous

Provisions. Subject to Section 8.06 hereof, all money

and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively

for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding

Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and the Indenture, to the payment,

either directly or through any paying agent (including the Issuer acting as paying agent) as the Trustee may determine, to the Holders

of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not

be segregated from other funds except to the extent required by law.

The Issuer shall pay and indemnify

the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S. Government Obligations deposited pursuant

to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which

by law is for the account of the Holders of the Outstanding Notes.

Anything in this Article VIII

to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon the written request of the Issuer

any money or U.S. Government Obligations held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized

firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion

delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect

an equivalent Legal Defeasance.

Section

8.06.         Repayment to Issuer.

Any money deposited with the Trustee or any paying agent, or then held by the Issuer, in trust for the payment of the principal of, premium

on, if any, or interest on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become

due and payable shall be paid to the Issuer on its written request or (if then held by the Issuer) shall be discharged from such trust;

and the Holder of such Note shall thereafter, as an unsecured creditor, look only to the Issuer for payment thereof, and all liability

of the Trustee or such paying agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon

cease.

Section

8.07.        Reinstatement.

If the Trustee or paying agent is unable to apply any Dollars or U.S. Government Obligations in accordance with Section 8.02 hereof,

as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting

such application, then the Issuer’s obligations under the Indenture and the Notes shall be revived and reinstated as though no deposit

had occurred pursuant to Section 8.02 hereof until such time as the Trustee or paying agent is permitted to apply all such money

in accordance with Section 8.02 hereof, as the case may be; provided, however, that, if the Issuer makes any

payment of principal of, premium on, if any, or interest on any Note following the reinstatement of their obligations, the Issuer shall

be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or paying agent.

ARTICLE

AMENDMENT; SUPPLEMENT AND WAIVER

Section

9.01.         Amendment; Supplement and Waiver. The following provisions of this Section 9.01 shall

apply with respect to the Indenture (as it relates to the Notes) and the Notes, in lieu of Section 9.02 of the Original Indenture. Amendments

of the Indenture and the Notes may be made by the Issuer and the Trustee with the written consent of the Holders of a majority in principal

amount of the then outstanding Notes (including consents obtained in connection with a tender offer or exchange offer for the Notes).

However, without the consent of each Holder of an affected Note, no amendment may, among other things:

(1)           reduce

the percentage in principal amount of Notes whose Holders must consent to an amendment;

(2)            reduce

the rate of or extend the time for payment of interest, including default interest, on any Note beyond the maximum time period for any

permitted extension or deferral or to increase the maximum time period for any such interest extension or deferral or to increase the

maximum number of times the Issuer may extend or defer such interest payment;

(3)            reduce

the principal of or extend the stated maturity of any Note;

(4)            reduce

the premium payable upon the redemption of any Note as described above under Article IV;

(5)           change

any obligation of the Issuer to pay additional amounts with respect to any Note;

(6)           make

any Notes payable in money other than U.S. dollars;

(7)           impair

the right of any Holder to receive payment of the principal of and premium, if any, and interest on such Holder’s Note or to institute

suit for the enforcement of any payment on or with respect to such Holder’s Note;

(8)           waive

a continuing Default or Event of Default in the payment of principal and premium, if any, and interest with respect to such Holder’s

Note; or

(9)           make

any change in the amendment provisions which require each Holder’s consent or in the waiver provisions.

The Holders of a majority

in principal amount of the outstanding Notes, on behalf of all such Holders, may waive any past or existing Default or Event of Default

with respect to the Notes (including any such waiver obtained in connection with a tender offer or exchange offer for the Notes), except

a Default or Event of Default in the payment of principal, premium or interest or in respect of a provision that under the Indenture cannot

be modified or amended without the consent of the Holder of each outstanding Note affected. A waiver by the Holders of Notes of compliance

with a covenant, a Default or an Event of Default will not constitute a waiver of compliance with such covenant or such Default or Event

of Default with respect to any other series of Debt Securities issued under the Indenture to which such covenant, Default or Event of

Default applies.

The consent of the Holders

is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves

the substance of the proposed amendment. After an amendment with the consent of the Holders under the Indenture becomes effective, the

Issuer is required to send to all Holders of Notes a notice briefly describing such amendment. However, the failure to give such notice

to all such Holders, or any defect therein, will not impair or affect the validity of the amendment.

The following provisions of

this Section 9.01 shall apply with respect to the Indenture (as it relates to the Notes) and the Notes in lieu of the provisions of Section

9.01 of the Original Indenture: Without the consent of any Holder, the Issuer and the Trustee may amend the Indenture to:

(1)            cure

any ambiguity, omission, defect or inconsistency;

(2)           provide

for the assumption by a successor of the obligations of the Issuer under the Indenture;

(3)           provide

for uncertificated Notes in addition to or in place of certificated Notes;

(4)           secure

the Notes or add guarantees with respect to the Notes or release guarantees with respect to the Notes in accordance with the terms thereof;

(5)           comply

with any requirement in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act of 1939, as amended

(the “Trust Indenture Act”);

(6)           add

to the covenants of the Issuer for the benefit of the Holders or surrender any right or power conferred upon the Issuer;

(7)           add

any additional events of default;

(8)           make

any change that does not adversely affect the rights under the Indenture of any Holder;

(9)           supplement

any of the provisions of the Indenture to facilitate the defeasance and discharge of Notes pursuant to the terms of the Indenture;

(10)         comply

with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act;

(11)         conform

the text of the Indenture to any provision of the “Description of the notes” included in the prospectus under which the Notes

were initially offered and sold, to the extent that such text of the indenture was intended to reflect such provision of such “Description

of the notes” as specified in an Officers’ Certificate; and

(12)         provide

for a successor trustee.

Capitalized terms used herein

shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

Interest. Plains All American Pipeline, L.P., a Delaware limited partnership (the “Issuer”), promises to pay

interest on the principal amount of this Security, in accordance with the provisions hereof and of the Indenture, on each June 15 and

December 15 (each, an “Interest Payment Date”), commencing [June 15, 2027] (subject to the right of the Issuer to defer the

payment of interest, but not beyond the Maturity Date, in accordance with the Indenture), (i) from and including [September 14, 2026]

to, but excluding, the First Reset Date at the rate of 6.750% per annum and (ii) except as provided in the Indenture, from and including

the First Reset Date, during each Reset Period at a rate per annum equal to the Five-year U.S. Treasury Rate as of the most recent Reset

Interest Determination Date plus a spread of 2.141 percentage points, to be reset on each Reset Date in accordance with the Indenture;

provided, that the interest rate on the Notes during any Reset Period will not reset below 6.750%. Interest on the Note shall be computed

on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date, Redemption Date or the Maturity Date of the Note

is not a Business Day at any place of payment, then payment of the principal, premium, if any, and interest may be made on the next Business

Day at that place of payment. In that case, no interest will accrue on the amount payable for the period from and after the applicable

Interest Payment Date, Redemption Date or Maturity Date, as the case may be.

So long as no Event of Default

with respect to the Notes has occurred and is continuing, the Issuer may, at its option, defer interest payments on the Notes, from time

to time, as set forth in Section 3.04 of the Supplemental Indenture.

To be included only if the Note is issued in global form.

A-2

Method of Payment. The Issuer shall pay interest on the Notes (except defaulted interest) to the Persons who are registered

Holders of Notes at the close of business on the June 1 and December 1 next preceding the Interest Payment Date, even if such Notes are

canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.17 of the Original Indenture

with respect to defaulted interest, and the Issuer shall pay principal (and premium, if any) of the Notes upon surrender thereof to the

Trustee or a paying agent on or after the Stated Maturity thereof. The Notes shall be payable as to principal, premium, if any, and interest

at the office or agency of the Trustee maintained for such purpose within or without The City and State of New York, 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 register of Holders,

and provided that payment by wire transfer of immediately available funds shall be required with respect to principal of and interest

and premium, if any, on, each Global Security and all other Notes the Holders of which shall have provided wire transfer instructions

to the Issuer or the paying agent on or prior to the applicable record date. 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.

Paying Agent and Registrar. Initially, U.S. Bank Trust Company, National Association, 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.

Indenture. The Issuer issued the Notes under a Subordinated Indenture, dated as of September 14, 2026 (the “Original

Indenture”), as supplemented by the First Supplemental Indenture, dated as of September 14, 2026 (the “Supplemental Indenture”

and, together with the Original Indenture, the “Indenture”) between the Issuer 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. The Notes are obligations of the Issuer initially in aggregate principal amount of $700,000,000.

The Issuer may issue an unlimited aggregate principal amount of Additional Notes under the Indenture. Any such Additional Notes that are

actually issued shall be treated as issued and outstanding Notes (and as the same series (with identical terms other than with respect

to the issue date, the date of first payment of interest, if applicable, and the payment of interest accruing prior to the issue date)

as the initial Notes) for all purposes of the Indenture, including waivers, amendments, redemptions and offers to purchase.

A-3

Optional Redemption.

the Notes, plus, subject to Section 3.05 of the Supplemental Indenture, accrued and unpaid interest on the Notes to, but excluding, the

Redemption Date.

Notice of Redemption; Selection of Notes.

Notice of redemption shall

be mailed at least 10 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered

address, except as provided in the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples

of $1,000, unless all of the Notes held by a Holder are to be redeemed. Unless the Issuer default in payment of the redemption price,

on and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption. Notwithstanding anything

to the contrary in the Original Indenture, if less than all the Notes are to be redeemed, the Trustee shall select the Notes or portions

thereof (in multiples of $1,000) to be redeemed (i) if the Notes are listed on an exchange, in compliance with the requirements of the

principal national securities exchange on which the Notes are listed, or (ii) if the Notes are not listed on an exchange or such exchange

has no selection requirements, on a pro rata basis, by lot or, if the Notes are in the form of one or more Global Securities, by such

method as the Depositary shall require.

Any redemption or notice

of redemption may be subject to conditions, and may be rescinded or cancelled, as provided in the Indenture.

Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 and

integral multiples of $1,000.  The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture.

the Issuer may require a Holder to pay any taxes or other governmental charges 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 or repurchase, except for the

unredeemed or unrepurchased portion of any Note being redeemed or repurchased 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 repurchased or during the period between

a record date and the corresponding Interest Payment Date.

A-4

Persons Deemed Owners. The registered Holder of a Note shall be treated as its owner for all purposes.

Amendment, Supplement and Waiver.

Subject to certain exceptions,

the Indenture or the Notes may be amended or supplemented with the consent of the Holders of a majority in aggregate principal amount

of the then Outstanding Notes, and any existing Default or compliance with any provision of the Indenture or the Notes may be waived with

the consent of the Holders of a majority in aggregate principal amount of the then Outstanding Notes. Without the consent of any Holder

of a Note, the Indenture or the Notes may be amended or supplemented for certain the purposes set forth in the Indenture.

10.

Defaults and Remedies. Upon certain Events of Default, the Trustee or the Holders of at least 33% in aggregate principal

amount of the then Outstanding Notes may declare all the Notes to be due and payable as provided in the Indenture. Holders may not enforce

the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal

amount of the then Outstanding Notes may direct the Trustee in its exercise of any trust or power. If and so long as the board of directors,

an executive committee of the board of directors or trust committee of Responsible Officers of the Trustee in good faith so determines,

the Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal,

premium, if any, or interest) if it determines that withholding notice is in their interests. The Holders of a majority in aggregate principal

amount of the Notes then Outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any past Default

or Event of Default and its consequences under the Indenture except as provided in the Indenture.

11.

Subordination. The indebtedness represented by the Notes is, to the extent and in a manner set forth in the Indenture, expressly

subordinated in right of payment to the prior payment in full of all Senior Indebtedness, as defined in the Indenture, and this Note is

issued subject to such provisions, and each Holder of this Note, by acceptance thereof, agrees to and shall be bound by such provisions

and authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination

as provided in the Indenture and appoints the Trustee its attorney-in-fact, as the case may be, for any and all such purposes.

12.

Trustee Dealings with Issuer. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from,

and perform services for the Issuer or its affiliates, and may otherwise deal with the Issuer or its affiliates, as if it were not the

Trustee.

13.

No Recourse Against Others. No past, present or future director, officer, partner, employee, incorporator, manager, stockholder,

unitholder or member of the Issuer, the General Partner, Plains All American GP or any other obligor on the Notes of any series, as such,

shall have any liability for any obligations of the Issuer or such other obligors under the Notes, the Indenture or for any claim based

on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability.

The waiver and release are part of the consideration for issuance of the Notes.

the Issuer has caused CUSIP and corresponding ISIN numbers to be printed on the Notes, and the Trustee may use CUSIP and corresponding
