 Section 1. The Securities. Subject to the terms and conditions
herein contained, the Issuers propose to issue and sell to the Initial Purchasers $400,000,000 aggregate principal amount of their
6 3/8% Senior Notes due 2022 (the
“Notes”), which will be unconditionally guaranteed on a senior basis as to principal, premium, if any, and interest (the “Guarantees”) by the Subsidiaries of the Partnership named in Schedule 4 hereto (each
individually, a “Guarantor” and collectively, the “Guarantors” and, together with the Non-Guarantor Subsidiaries (other than the entities named in Schedule 5 hereto), the “Material
Subsidiaries”). The Guarantors, other than Sound Pipeline Company, LLC, a Washington limited liability company (the “Washington Guarantor”), are referred to herein as the “Delaware Guarantors.” The Notes
are to be issued under an indenture (the “Indenture”) to be dated as of January 31, 2012, by and among the Issuers, the Guarantors and U.S. Bank National Association, as Trustee (the “Trustee”).

 The Notes will be offered and sold to the Initial Purchasers without being registered under the Securities Act of
1933, as amended (the “Act”), in reliance on exemptions therefrom. 
 In connection with the sale of the Notes,
the Issuers have prepared a preliminary offering memorandum dated January 26, 2012 (including any documents incorporated therein by reference, the “Preliminary Memorandum”) setting forth or including a description of the terms
of the Notes, the terms of the offering of the Notes, a description of the Partnership and any material developments relating to the Partnership after the date of the most recent historical financial statements included therein. As used herein,
“Pricing Disclosure Package” shall mean the Preliminary Memorandum, as supplemented or amended by the written communications listed on Annex A hereto in the most recent form that has been prepared and delivered by the Issuers
to the Initial Purchasers in connection with their solicitation of offers to purchase Notes prior to the time when sales of the Notes were first made (the “Time of Execution”). Promptly after the Time of Execution and in any event
no later than the second Business Day following the Time of Execution, the Issuers will prepare and deliver to each Initial Purchaser a final offering memorandum (including any documents incorporated therein by reference, the “Final
Memorandum”), which will consist of the Preliminary Memorandum with such changes therein as are required to reflect the information contained in the amendments or supplements listed on Annex A hereto. The Issuers hereby confirm that
each of the Issuers has authorized the use of the Pricing Disclosure Package, the Final Memorandum and the Recorded Road Show (defined below) in connection with the offer and sale of the Notes by the Initial Purchasers. 

All references in this Agreement to financial statements and schedules and other information which is “contained,”
“included” or “stated” in the Offering Memorandum (as defined below) (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which are
incorporated by reference in the Offering Memorandum; and all references in this Agreement to amendments or supplements to the Offering Memorandum shall be deemed to mean and include the filing of any document under the Securities Exchange Act of
1934 (the “Exchange Act”) which is incorporated by reference in the Offering Memorandum. 
 The Initial
Purchasers and their direct and indirect transferees of the Notes will be entitled to the benefits of the Registration Rights Agreement, substantially in the form attached hereto as Exhibit A (the “Registration Rights
Agreement”), pursuant to which the Issuers and the Guarantors will agree, among other things, to file a registration statement (the “Registration Statement”) with the Securities and Exchange Commission (the
“Commission”) registering the 

  
 2 

 
Notes or the Exchange Notes (as defined in the Registration Rights Agreement) under the Act, unless (i) the Notes are freely transferable without volume restrictions by holders that are not
affiliates of the Issuers in accordance with Rule 144 (or any similar provision then in effect), (ii) the Notes do not bear a restrictive legend and (iii) the Notes do not bear a restricted CUSIP number as of the 370th day after the Closing Date (as defined in Section 3 below).

 Section 2. Representations and Warranties. As of the Time of Execution and at the Closing Date, the Issuers and the
Guarantors jointly and severally represent and warrant to and agree with each of the Initial Purchasers as follows (references in this Section 2 to the “Offering Memorandum” are to (i) the Pricing Disclosure Package in the
case of representations and warranties made as of the Time of Execution and (ii) both the Pricing Disclosure Package and the Final Memorandum in the case of representations and warranties made at the Closing Date): 

(a) The Preliminary Memorandum, on the date thereof, did not contain any untrue statement of a material fact or omit to
state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. At the Time of Execution, the Pricing Disclosure Package did not, and on the Closing Date, will not, and
the Final Memorandum as of its date and on the Closing Date will not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were
made, not misleading; provided, however, that the Issuers and the Guarantors make no representation or warranty as to the information contained in or omitted from the Pricing Disclosure Package and Final Memorandum, in reliance upon
and in conformity with information furnished in writing to the Partnership by or on behalf of the Initial Purchasers through the Representatives specifically for inclusion therein. The Issuers and the Guarantors have not distributed or referred to
and will not distribute or refer to any written communications (as defined in Rule 405 of the Act) that constitute an offer to sell or solicitation of an offer to buy the Notes (each such communication by the Issuers and the Guarantors or each of
their agents and representatives (other than the Pricing Disclosure Package and Final Memorandum) an “Issuer Written Communication”) other than the Pricing Disclosure Package, the Final Memorandum and the recorded electronic road
show made available to investors (the “Recorded Road Show”). Any information in an Issuer Written Communication that is not otherwise included in the Pricing Disclosure Package and the Final Memorandum does not conflict with the
Pricing Disclosure Package or the Final Memorandum and, each Issuer Written Communication, when taken together with the Pricing Disclosure Package does not at the Time of Execution and when taken together with the Final Memorandum at the Closing
Date will not, contain any 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 under which they were made, not misleading.

stated therein at the respective dates or for the respective periods to which they apply, and have been prepared in accordance with generally accepted accounting principles consistently applied throughout the periods involved, except to the extent
disclosed therein. The summary and selected financial, statistical and operating information in the Offering Memorandum is accurately presented in all material respects and prepared on a basis consistent with the audited and unaudited historical
consolidated financial statements, as applicable, from which it has been derived. PricewaterhouseCoopers LLP, which has certified certain financial statements of the Partnership and its Subsidiaries and delivered its report with respect to the

the rules and regulations promulgated thereunder. The interactive data in eXtensbile Business Reporting Language included or incorporated by reference in the Pricing Disclosure Package and the Final Memorandum fairly presents the information called
for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto in all material respects. 
 (r) Except as set forth or contemplated in the Offering Memorandum, there is (i) no action, suit or proceeding before or by any court, arbitrator or governmental agency, body or official, domestic or

subject, (ii) to the knowledge of the Partnership, no statute, rule, regulation or order that has been enacted, adopted or issued by any governmental agency and (iii) no injunction, restraining order or order of any nature issued by a
federal or state court or foreign court of competent jurisdiction to which any of the Issuers or Material Subsidiaries is or may be subject, that, in the case of clauses (i), (ii) and (iii) above, is reasonably expected to
(A) individually or in the aggregate have a Material Adverse Effect, (B) prevent the consummation of the issuance or sale of the Notes to be sold hereunder, or (C) draw into question the validity of this Agreement. 

(s) Each of the Issuers and the Material Subsidiaries possesses such permits, licenses, approvals, consents and other
authorizations (collectively, “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct their respective businesses, except where the failure so to possess
would not, individually or in the aggregate, result in a Material Adverse Effect; each of the Issuers and each Material Subsidiary is in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to
comply would not, individually or in the aggregate, result in a Material Adverse Effect; all of the 

  
 8 

 
Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect
would not, individually or in the aggregate, result in a Material Adverse Effect; and except as described in the Offering Memorandum, neither of the Issuers and no Material Subsidiary has received any notice of proceedings relating to the revocation
or modification of any such Governmental Licenses which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Effect. 

(t) Since the date of the most recent financial statements appearing in the Offering Memorandum and except as set forth
or contemplated in the Offering Memorandum, (i) none of the Issuers or the Material Subsidiaries has incurred any liabilities or obligations, direct or contingent, or entered into or agreed to enter into any transactions or contracts (written
or oral) not in the ordinary course of business, which liabilities, obligations, transactions or contracts would, individually or in the aggregate, be material to the general affairs, management, business, condition (financial or otherwise),
prospects or results of operations of the Partnership and its Subsidiaries, taken as a whole and (ii) the Partnership has not purchased any of its outstanding equity interests, nor declared, paid or otherwise made any distribution of any kind
on its equity interests (other than (A) the Partnership’s quarterly distributions and (B) with respect to any of the Subsidiaries, the purchase of, or dividend or distribution on, capital stock or equity interests owned by the
Partnership). 
 (u) Except as set forth or contemplated in the Offering Memorandum, each of the Issuers and the
Material Subsidiaries has filed all foreign, federal, state and local tax returns that are required to be filed or has requested extensions thereof, except in any case in which the failure so to file, individually or in the aggregate, would not have
a Material Adverse Effect, and has paid all taxes required to be paid by it and any other assessment, fine or penalty levied against it, to the extent that any of the foregoing is due and payable, except for any such assessment, fine or penalty that
is currently being contested in good faith or as, individually or in the aggregate, would not have a Material Adverse Effect. 
 (v) Immediately after the consummation of the transactions contemplated by this Agreement, the fair value and present fair saleable value of the assets of each of the Issuers and the Material Subsidiaries
(each on a consolidated basis) will exceed the sum of its stated liabilities and identified contingent liabilities. Each of the Issuers and the Guarantors is not now nor after giving effect to the issuance of the Notes and the execution, delivery
and performance of this Agreement, the Registration Rights Agreement and the Indenture, and the consummation of the transactions contemplated thereby or described in the Offering Memorandum, will be (i) insolvent, (ii) left with
unreasonably small capital with which to engage in its anticipated business or (iii) incurring debts or other obligations beyond its ability to pay such debts or obligations as they become due. 

(w) Any statistical and market-related data included in the Offering Memorandum are based on or derived from sources that
each of the Issuers and the Guarantors believe to be reliable and accurate, and the Issuers have obtained the written consent to the use of such data from such sources to the extent required.

Memorandum, (ii) Liens that arise under the Partnership Credit Agreement or the TRI Credit Agreement or (iii) to the extent the failure to have such title or the existence of such Liens would not, individually or in the aggregate, have a
Material Adverse Effect; provided that, with respect to any real property and buildings held under lease by the Partnership and the Material Subsidiaries, such real property and buildings are held under valid and subsisting and enforceable
leases with such exceptions as do not materially interfere with the use of the properties of the Partnership and the Material Subsidiaries taken as a whole as they have been used in the past as described in the Offering Memorandum and are proposed
to be used in the future as described in the Offering Memorandum, except to the extent the failure to hold such valid and subsisting and enforceable leases would not, individually or in the aggregate, have a Material Adverse Effect. 

(y) The Partnership and the Material Subsidiaries have such easements or rights-of-way (collectively,
“rights-of-way”) as are necessary to conduct their business in the manner described, and subject to the limitations contained, in the Offering Memorandum, except for (i) qualifications, reservations and encumbrances that would
not have, individually or in the aggregate, a Material Adverse Effect, (ii) such rights-of-way that, if not obtained, would not have, individually or in the aggregate, a Material Adverse Effect and (iii) rights-of-way held by affiliates of
the Partnership as nominee for the benefit of the Partnership and the Material Subsidiaries.

such exceptions that would not reasonably be expected to result in a Material Adverse Effect, (i) each of the Issuers and each Material Subsidiary owns or possesses, or can acquire or use on reasonable terms, adequate patents, patents rights,

Subsidiary has not received any notice and is not otherwise aware of any infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances that would render any Intellectual
Property invalid or inadequate to protect any of its interest therein. 
 (aa) There are no legal or
governmental proceedings pending or, to the knowledge of the Partnership, threatened or contemplated, against either of the Issuers or the Material Subsidiaries or any of their respective properties or assets that would be required to be described
in a prospectus pursuant to the Act that are not described in the Offering Memorandum, nor are there any agreements, contracts, indentures, leases or other instruments that would be required to be described in a prospectus pursuant to the

  
 10 

 
Act that are not described in the Offering Memorandum. Except as set forth or contemplated in the Pricing Disclosure Package and the Final Memorandum, to the knowledge of the Partnership, no
legal or governmental proceedings are pending or threatened to which either of the Issuers or any of the Material Subsidiaries is a party or to which the property or assets of the Issuers or any Material Subsidiary is subject that, if determined
adversely to the Issuers or the Material Subsidiaries, could be reasonably expected to result, individually or in the aggregate, in a Material Adverse Effect. 
 (bb) The Partnership is in compliance in all material respects with all applicable provisions of the Sarbanes Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the

would reasonably be expected to result in the receipt of such notice; and (iv) to the knowledge of the Partnership, there are no releases of Hazardous Materials (as defined below) that would reasonably be expected to give rise to liabilities or
obligations under any Environmental Law. 
 For purposes of this Agreement: (i) “Environmental Law” means

Initial Purchasers as follows: 
 (a) Until the later of (i) the completion of the distribution of the
Notes by the Initial Purchasers and (ii) the Closing Date, the Issuers will not amend or supplement the Pricing Disclosure Package or the Final Memorandum or otherwise distribute or refer to any Issuer Written Communication (other than the

Initial Purchasers or counsel for the Initial Purchasers, make any amendments or supplements to the Pricing Disclosure Package and the Final Memorandum that may be necessary or advisable in connection with the resale of the Notes by the Initial
Purchasers. 
 (b) The Issuers will cooperate with the Initial Purchasers in arranging for the qualification of
the Notes for offering and sale under the securities or “Blue Sky” laws of such jurisdictions as the Initial Purchasers may designate and will continue such qualifications in effect for as long as may be necessary to complete the resale of
the Notes; provided, however, that in connection therewith, the Issuers shall not be required to qualify as a foreign limited partnership or corporation or to execute a general consent to service of process in any jurisdiction or
subject itself to taxation in any such jurisdiction where it is not then so subject. 
 (c) (1) If, at any time
prior to the completion of the sale by the Initial Purchasers of the Notes, any event occurs or information becomes known as a result of which the Final Memorandum as then amended or supplemented would include any untrue statement of a material
fact, or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if for any other reason it is necessary at any time to amend or supplement the Final
Memorandum to comply with applicable law, the Issuers will promptly notify the Initial Purchasers thereof and will prepare, at the expense of the Partnership, an amendment or supplement to the Final Memorandum that corrects such statement or

  
 16 

 
omission or effects such compliance and (2) if at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which any of the Pricing
Disclosure Package as then amended or supplemented would include any 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 under which they were
made, not misleading or any Issuer Written Communication would conflict with the Pricing Disclosure Package as then amended or supplemented, or (ii) it is necessary to amend or supplement any of the Pricing Disclosure Package so that any of the
Pricing Disclosure Package or any Issuer Written Communication will comply with law, the Issuers will immediately notify the Initial Purchasers thereof and forthwith prepare and, subject to paragraph (a) above, furnish to the Initial Purchasers
such amendments or supplements to any of the Pricing Disclosure Package or any Issuer Written Communication (it being understood that any such amendments or supplements may take the form of an amended or supplemented Final Memorandum) as may be
necessary so that the statements in any of the Pricing Disclosure Package as so amended or supplemented will not, in light of the circumstances under which they were made, be misleading or so that any Issuer Written Communication will not conflict
with the Pricing Disclosure Package or so that the Pricing Disclosure Package or any Issuer Written Communication as so amended or supplemented will comply with law. 

(d) The Issuers will, without charge, provide to the Initial Purchasers and to counsel for the Initial Purchasers as many
copies of the Pricing Disclosure Package, any Issuer Written Communication and the Final Memorandum or any amendment or supplement thereto as the Initial Purchasers may reasonably request.

Pricing Disclosure Package and the Final Memorandum; provided, however, that the Issuers do not need to furnish such financial statements to the Initial Purchasers if they are available on the Commission’s website. 

(g) None of the Issuers or any of its affiliates that it controls will, and the Issuers will use their commercially
reasonable efforts to cause their other affiliates (other than Warburg Pincus LLC and its affiliates (other than Targa Resources Corp. and its subsidiaries)) not to, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of
any “security” (as defined in the Act) that could be integrated with the sale of the Notes in a manner which would require the registration under the Act of the Notes. 

(h) The Issuers will not, and will not permit any of their subsidiaries or their respective affiliates that they control
or persons acting on their behalf to, and the Issuers will use their commercially reasonable efforts to cause their other affiliates (other than Warburg Pincus LLC and its affiliates (other than Targa Resources Corp. and its

  
 17 

 
subsidiaries)) not to, engage in any form of general solicitation or general advertising (as those terms are used in Regulation D under the Act) in connection with the offering of the Notes or in
any manner involving a public offering within the meaning of Section 4(2) of the Act. 
 (i) For so long as
any of the Notes remain outstanding, the Issuers will make available at their expense, upon request, to any holder of such Notes and any prospective purchasers thereof the information specified in Rule 144A(d)(4) under the Act, unless either of
the Issuers is then subject to Section 13 or 15(d) of the Exchange Act. 
 (j) The Issuers will use their
commercially reasonable best efforts to permit the Notes to be eligible for clearance and settlement through The Depository Trust Company. 
 (k) During the period beginning on the date hereof and continuing to the date that is 45 days after the Closing Date, without the prior written consent of Deutsche Bank Securities Inc., the Issuers will
not offer, sell, contract to sell or otherwise dispose of, except as provided hereunder, any securities of the Issuers (or guaranteed by the Issuers) that are substantially similar to the Notes (except for the Notes which would be issuable pursuant
to the exchange offer described in the Preliminary Memorandum and the Final Memorandum). 
 (l) In connection
with Notes offered and sold in an offshore transaction (as defined in Regulation S) the Issuers will not register any transfer of such Notes not made in accordance with the provisions of Regulation S and will not, except in accordance with the
provisions of Regulation S, if applicable, issue any such Notes in the form of definitive securities. 
 (m)
None of the Issuers or any of their affiliates that they control will engage in any directed selling efforts (as that term is defined in Regulation S) with respect to the Notes. 

(n) For a period of one year (calculated in accordance with paragraph (d) of Rule 144 under the Act) following
the date any Notes are acquired by either of the Issuers or any of their affiliates, if the Notes are Registrable Securities (as defined in the Registration Rights Agreement), neither of the Issuers or any of their respective affiliates that they
control will sell any such Notes. 
 (o) For so long as any Notes are outstanding, the Issuers and the
Guarantors will conduct their operations in a manner that will not subject the Issuers or any Guarantor to registration as an investment company under the Investment Company Act. 

(p) Each Note will bear a legend substantially to the following effect until such legend shall no longer be necessary or
advisable because the Notes are no longer subject to the restrictions on transfer described therein:

consummation of the transactions contemplated hereby and thereby (including, without limitation, the issuance and sale of the Notes to the Initial Purchasers) will not constitute or result in a breach or a default under (or an event that with notice
or passage of time or both would constitute a default under) any of (i) the terms or provisions of any Contract listed on Annex B hereto, (ii) the Organizational Documents of any of the Issuers or the Guarantors, or (iii) any
statute, judgment, decree, order, rule or regulation (excluding any securities laws, rules or regulations) known to such counsel to be applicable to the Issuers or any of the Guarantors or any of their respective properties or assets, except, with
respect to clauses (i) and (iii) only, for any such conflict, breach or violation that could not reasonably be expected to, individually or in the aggregate, have a Material Adverse Effect. 

(xi) No consent, approval, authorization or order of any governmental authority is required for the issuance and sale by
the Issuers of the Notes to the Initial Purchasers or the consummation by the Issuers of the other transactions contemplated hereby, except such as may be required under securities laws, as to which such counsel need express no opinion in this
paragraph, and those which have previously been obtained. 
 (xii) None of the Issuers or the Guarantors is, or
immediately after the sale of the Notes to be sold hereunder and the application of the proceeds from such sale (as described in the Pricing Disclosure Package and the Final Memorandum under the caption “Use of Proceeds”) will be, an
“investment company” as such term is defined in the Investment Company Act of 1940, as amended. 

(xiii) No registration under the Act of the Notes is required in connection with the sale of the Notes to the Initial
Purchasers or in connection with the initial resale of the Notes by the Initial Purchasers, in each case, as contemplated by this Agreement and the Pricing Disclosure Package and the Final Memorandum, and prior to the commencement of the Exchange
Offer (as defined in the Registration Rights Agreement) or the effectiveness of the Shelf Registration Statement (as defined in the Registration Rights Agreement), the Indenture is not required to be qualified under the TIA.

 At the time the foregoing opinion is delivered, Vinson & Elkins L.L.P. shall
additionally state that it has participated in conferences with officers and other representatives of the Issuers, representatives of the independent registered public accountants for the Issuers, representatives of the Initial Purchasers and
counsel for the Initial Purchasers, at which conferences the contents of the Pricing Disclosure Package and the Final Memorandum and related matters were discussed, and, although it has not independently verified, and is not passing on and assumes
no responsibility for the accuracy, completeness or fairness of the statements contained in the Pricing Disclosure Package and the Final Memorandum (except to the extent specified in subsection 7(a)(ix)), no facts have come to its attention
which lead it to believe that the Pricing Disclosure Package, as of the Time of Execution or at the Closing Date, or that the Final Memorandum, as of its date or at the Closing Date, contained an untrue statement of a material fact or omitted to
state a material fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading (it being understood that such firm need make no comment with respect to the financial statements and
related notes thereto and the other financial and accounting data derived from the Issuers’ books and records included in the Pricing Disclosure Package or the Final Memorandum).

quantities as the Initial Purchasers shall reasonably request. 
 Section 8. Offering of Notes; Restrictions on Transfer.

 (a) Each of the Initial Purchasers agrees with the Issuers (as to itself only) that (i) it has not and will not solicit
offers for, or offer or sell, the Notes by any form of general solicitation or general advertising (as those terms are used in Regulation D under the Act) or in any manner involving a public offering within the meaning of Section 4(2) of the
Act; and (ii) it has and will solicit offers for the Notes only from, and will offer the Notes only to (A) in the case of offers inside the United States, persons whom the Initial Purchasers reasonably believe to be QIBs, in transactions
under Rule 144A and (B) in the case of offers outside the United States, to persons other than U.S. persons (“non-U.S. purchasers,” which term shall include dealers or other professional fiduciaries in the United States
acting on a discretionary basis for non-U.S. beneficial owners (other than an estate or trust)); provided, however, that, in the case of this clause (B), in purchasing such Notes such persons are deemed to have represented and agreed
as provided under the caption “Transfer Restrictions” contained in the Pricing Disclosure Package and the Final Memorandum. 

  
 26 

 (b) Each of the Initial Purchasers represents and warrants (as to itself only) that
(1) it is a QIB and (2) with respect to offers and sales outside the United States that (i) it has and will comply with all applicable laws and regulations in each jurisdiction in which it acquires, offers, sells or delivers Notes or
has in its possession or distributes any Pricing Disclosure Package or Final Memorandum or any such other material, in all cases at its own expense; (ii) the Notes have not been and will not be offered or sold within the United States or to, or
for the account or benefit of, U.S. persons except in accordance with Regulation S under the Act or pursuant to an exemption from the registration requirements of the Act; and (iii) it has offered the Notes and will offer and sell the Notes
(A) as part of its distribution at any time and (B) otherwise until 40 days after the later of the commencement of the offering and the Closing Date, only in accordance with Rule 903 of Regulation S and, accordingly, neither it nor
any persons acting on its behalf have engaged or will engage in any directed selling efforts (within the meaning of Regulation S) with respect to the Notes, and any such persons have complied and will comply with the offering restrictions
requirement of Regulation S. 
 (c) Each Initial Purchaser, severally and not jointly, represents and warrants and agrees with
the Issuers that: 
 (i) in relation to each Member State of the European Economic Area which has implemented
the Prospectus Directive (as defined below) (each, a “Relevant Member State”), with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant
Implementation Date”), it has not made and will not make an offer of Notes to the public in that Relevant Member State, except that it may, with effect from and including the Relevant Implementation Date, make an offer of Notes to the
public in that Relevant Member State at any time: (A) to any legal entity which is a qualified investor as defined in the Prospectus Directive; (B) to fewer than 100 or, if the Relevant Member State has implemented the relevant provision
of the 2010 PD Amending Directive (as defined below), 150, natural or legal persons (other than qualified investors as defined in the Prospectus Directive), as permitted under the Prospectus Directive, subject to obtaining the prior consent of the
Representatives for any such offer; or (C) in any other circumstances falling within Article 3(2) of the Prospectus Directive; 
 For the purposes of this provision, the expression an “offer of notes to the public” in relation to any Notes in any Relevant Member State means the communication in any form and by any
means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to purchase or subscribe for the Notes, as the same may be varied in that Member State by any measure implementing the
Prospectus Directive in that Member State, the expression “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State),
and includes any relevant implementing measure in the Relevant Member State and the expression “2010 PD Amending Directive” means Directive 2010/73/EU. 

  
 27 

 (ii) it has only communicated or caused to be communicated and will only
communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act of 2000 (the “FSMA”)) received by it in connection
with the issue or sale of the Notes in circumstances in which Section 21(1) of the FSMA does not apply to the Issuers; and 
 (iii) it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the Notes in, from or otherwise involving the United Kingdom.

 Terms used in this Section 8 and not defined in this Agreement have the meanings given to them in Regulation S.

 Section 9. Indemnification and Contribution. 
 (a) The Issuers and the Guarantors, jointly and severally, agree to indemnify and hold harmless the Initial Purchasers, their directors, officers, affiliates and each person, if any, who controls any
Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which any Initial Purchaser, any such director, officer, affiliate or controlling person
may become subject under the Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon the following: 

(i) any untrue statement or alleged untrue statement of any material fact contained in the Pricing Disclosure Package,
any Issuer Written Communication or Final Memorandum or any amendment or supplement thereto; or 
 (ii) the
omission or alleged omission to state, in the Pricing Disclosure Package, any Issuer Written Communication or the Final Memorandum or any amendment or supplement thereto, a material fact necessary to make the statements therein not misleading;

 and will reimburse, as incurred, the Initial Purchasers, any such director, officer, affiliate and controlling person for any legal or other
expenses reasonably incurred by the Initial Purchasers, their directors, officers, affiliates or controlling persons in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim,
damage, liability or action; provided, however, neither the Issuers nor the Guarantors will be liable in any such case to the extent that any such loss, claim, damage, expense or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in the Pricing Disclosure Package or Final Memorandum or any amendment or supplement thereto in reliance upon and in conformity with written information concerning such
Initial Purchaser furnished to the Partnership by the Initial Purchasers through the Representatives specifically for use therein. The indemnity provided for in this Section 9 will be in addition to any liability that the Partnership may
otherwise have to the indemnified parties. Neither the Issuers nor the Guarantors will be liable under this Section 9 for any settlement of any claim or action effected without its prior written consent, which shall not be unreasonably
withheld. 

  
 28 

 (b) Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless
each of the Issuers and Guarantors, and their respective directors, officers and each person, if any, who controls the Issuers or Guarantors within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses,
claims, damages or liabilities to which the Issuers or Guarantors or any such director, officer or controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Pricing Disclosure Package or Final Memorandum or any amendment or supplement thereto, or
(ii) the omission or the alleged omission to state therein a material fact necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with written information concerning the Initial Purchasers, furnished to the Issuers and Guarantors by the Initial Purchasers through the Representatives specifically for use
therein; and subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses reasonably incurred by the Issuers or Guarantors or any such director, officer or controlling person in
connection with investigating or defending against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action in respect thereof. The indemnity provided for in this Section 9 will be in addition
to any liability that the Initial Purchasers may otherwise have to the indemnified parties. The Initial Purchasers shall not be liable under this Section 9 for any settlement of any claim or action effected without their consent, which shall
not be unreasonably withheld. 
 (c) Promptly after receipt by an indemnified party under this Section 9 of notice of the
commencement of any action for which such indemnified party is entitled to indemnification under this Section 9, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9,
notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the extent such
failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification
obligation provided in paragraphs (a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to
participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however,
that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the
indemnifying party, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the 

  
 29 

 
indemnified party within a reasonable time after receipt by the indemnifying party of notice of the institution of such action, then, in each such case, the indemnifying party shall not have the
right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties.
After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such
indemnified party under this Section 9 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party
shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one
separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Initial Purchasers in the case
of paragraph (a) of this Section 9 or the Issuers and Guarantors in the case of paragraph (b) of this Section 9, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who
are parties to such action or actions) or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. All fees and expenses reimbursed pursuant to this
paragraph (c) shall be reimbursed as they are incurred. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by
such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnifying party waived in writing its rights under this Section 9, in which case the
indemnified party may effect such a settlement without such consent. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of any pending or threatened proceeding in respect of
which any indemnified party is or could have been a party, or indemnity could have been sought hereunder by any indemnified party, unless such settlement (A) includes an unconditional written release of the indemnified party, in form and
substance reasonably satisfactory to the indemnified party, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on
behalf of any indemnified party. 
 (d) In circumstances in which the indemnity agreement provided for in the preceding
paragraphs of this Section 9 is unavailable to, or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for
just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect
(i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Notes or if the allocation provided by the foregoing clause (i) is not permitted by
applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions
that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Issuers and Guarantors on the one hand 

  
 30 

 
and the Initial Purchasers on the other shall be deemed to be in the same proportion as the total proceeds from the offering (after deducting discounts and commissions but before deducting
expenses) received by the Issuers and Guarantors bear to the total discounts and commissions received by such Initial Purchaser. The relative fault of the parties 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 Issuers and Guarantors on the one hand, or such Initial Purchaser on the other, the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The Issuers, the Guarantors and the
Initial Purchasers agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations
referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Initial Purchaser shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts,
commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of the untrue or alleged untrue statements
or the omissions or alleged omissions to state a material fact, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The obligations of the Initial Purchasers are several and not joint. For purposes of this paragraph (d), each director, officer and affiliate of the Initial Purchasers and each person, if any, who controls any
Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each director of either of the Issuers or any of the Guarantors, each
officer of either of the Issuers or any of the Guarantors and each person, if any, who controls either of the Issuers or any of the Guarantors within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the
same rights to contribution as the Partnership. 
 Section 10. Survival Clause. The respective representations,
warranties, agreements, covenants, indemnities and other statements of each of the Issuers, Guarantors, their respective officers and the Initial Purchasers set forth in this Agreement or made by or on behalf of them pursuant to this Agreement shall
remain in full force and effect, regardless of (i) any investigation made by or on behalf of any of the Issuers, Guarantors, any of their respective officers or directors, the Initial Purchasers, any of their officers, directors, affiliates or
controlling persons referred to in Section 9 hereof and (ii) delivery of and payment for the Notes. The respective agreements, covenants, indemnities and other statements set forth in Sections 6, 9, 10 and 15 hereof shall remain in
full force and effect, regardless of any termination or cancellation of this Agreement. 

  
 31 

 Section 11. Termination. 

(a) This Agreement may be terminated in the sole discretion of the Initial Purchasers by notice to the Issuers given prior to the Closing
Date in the event that the Issuers shall have failed, refused or been unable to perform all obligations and satisfy all conditions on its part to be performed or satisfied hereunder at or prior thereto or, if, after the date hereof and at or prior
to the Closing Date, 
 (i) trading in securities of the Partnership shall have been suspended by the
Commission or the New York Stock Exchange; 
 (ii) there shall have been, in the sole judgment of the
Representatives, any event or development that, individually or in the aggregate, has or could be reasonably likely to have a Material Adverse Effect (including without limitation a change in control of the Issuers or the Guarantors), except in each
case as described in the Pricing Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto); 
 (iii) trading in securities generally on the New York Stock Exchange shall have been suspended or materially limited or minimum or maximum prices shall have been established on any such exchange or
market; 
 (iv) a banking moratorium shall have been declared by New York or United States authorities or a
material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred; 
 (v) there shall have been (A) an outbreak or escalation of hostilities between the United States and any foreign power or (B) an outbreak or escalation of any other insurrection or armed
conflict involving the United States or any other national or international calamity or emergency, which in the case of (A) and (B) above and in the sole judgment of the Representatives, makes it impracticable or inadvisable to proceed
with the offering or the delivery of the Notes as contemplated by the Pricing Disclosure Package and the Final Memorandum; or 
 (vi) any securities of the Partnership shall have been downgraded by any nationally recognized statistical rating organization or any such organization shall have publicly announced that it has under
surveillance or review, or has changed its outlook with respect to, its ratings of any securities of the Partnership (other than an announcement with positive implications of a possible upgrading). 

(b) Termination of this Agreement pursuant to this Section 11 shall be without liability of any party to any other party except as
provided in Section 10 hereof. 
 Section 12. Information Supplied by the Initial Purchasers. The statements set
forth in the last paragraph on the front cover page (as such paragraph is supplemented by the item on Annex A) and in the third paragraph and the eighth through twelfth paragraphs under the heading “Plan of Distribution” in the
Preliminary Memorandum and the Final Memorandum (to the extent such statements relate to the Initial Purchaser) constitute the only information furnished by the Initial Purchasers to the Issuers for the purposes of Sections 2(a) and 9 hereof.

Initial Purchasers, the Issuers and their respective successors and legal representatives, and nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim

 33 

 Section 16. No Advisory or Fiduciary Responsibility. The Issuers and the Guarantors
acknowledge and agree that (i) the purchase and sale of the Notes pursuant to this Agreement is an arm’s-length commercial transaction between the Issuers, on the one hand, and the Initial Purchasers, on the other, (ii) in connection
therewith and with the process leading to such transaction each Initial Purchaser is acting solely as a principal and not the agent or fiduciary of any of the Issuers, (iii) no Initial Purchaser has assumed an advisory or fiduciary
responsibility in favor of any of the Issuers with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising any of the Issuers on other matters)
