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 April 5, 2018 (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

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 are “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

their direct and indirect transferees of the Notes will be entitled to the benefits of a Registration Rights Agreement (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 Notes or the Exchange Notes (as defined in the

binding obligations of the Issuers, entitled to the benefits of the Indenture, and enforceable against the Issuers in accordance with their terms, except that the enforcement thereof may be subject to the Enforceability Exceptions. 

(viii) The Issuers and the Covered Guarantors have all requisite partnership, limited liability company or corporate power and
authority to execute, deliver and perform their obligations under the Registration Rights Agreement; the Registration Rights Agreement has been duly and validly authorized by the Issuers and the Covered Guarantors and, when duly executed and
delivered by the Issuers and the Covered Guarantors (assuming due authorization, execution and delivery thereof by the Initial Purchasers and SouthOk), will constitute the valid and legally binding agreement of the Issuers and the Guarantors,
enforceable against the Issuers and the Guarantors in accordance with its terms, except that (A) the enforcement thereof may be subject to the Enforceability Exceptions and (B) any rights to indemnity or contribution thereunder may be
limited by federal and state securities laws and public policy considerations. 
 (ix) The Issuers and the Covered
Guarantors have all requisite corporate, partnership or limited liability company power and authority to execute, deliver and perform their obligations under this Agreement and to consummate the transactions contemplated hereby; this Agreement and
the consummation by the Issuers and the Covered Guarantors of the transactions contemplated hereby have been duly and validly authorized by the Issuers and the Covered Guarantors. This Agreement has been duly executed and delivered by the Issuers
and the Covered Guarantors. 
 (x) (a) The descriptions of the Indenture, the Notes and the Registration Rights Agreement
contained in the Pricing Disclosure Package and the Final Memorandum are accurate in all material respects, and (b) the statements under the caption “Certain United States Federal Income Tax Considerations” in the Pricing Disclosure
Package and the Final Memorandum insofar as they purport to constitute a summary of United States federal tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the matters described therein in all
material respects, subject to the assumptions and qualifications set forth therein. 
 (xi) The execution, delivery and
performance of this Agreement, the Indenture, the Registration Rights Agreement and the 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 

  
 23 







 
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 Covered 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 Covered 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. 
 (xii) 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. 
 (xiii) None of the Issuers or the Covered 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. 
 (xiv) 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)(x)), 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).

documents, opinions, certificates, letters, schedules and instruments in such 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(a)(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 qualified institutional
buyers in transactions under Rule 144A (each, a “QIB”) 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. 
 (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) 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 (ii) it has offered the Notes and will offer and sell the Notes (A) as part of its distribution at

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. 

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

  
 27 







 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 Representative 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. 

(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 

  
 28 







 
the Initial Purchasers through the Representative 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 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 

  
 29 







 
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 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 

  
 30 







 
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. 
 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 or Targa Resources Corp. shall have been
suspended by the Commission or the New York Stock Exchange; 
 (ii) there shall have been, in the sole judgment of the
Representative, 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; 

  
 31 







 (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
Representative, 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. Default of One or More of the
Several Initial Purchasers. 
 (a) If any one or more of the several Initial Purchasers shall fail or refuse to purchase
the Notes that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of the Notes which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the
aggregate number of the Notes to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the number of Notes set forth opposite their respective names
on Schedule 1 bears to the aggregate number of the Notes set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be
specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Notes which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused
to purchase on the Closing Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase the Notes and the aggregate number of the Notes with respect to which such default occurs exceeds 10% of the aggregate number of the Notes
to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Issuers for the purchase of such Notes are not made within 48 hours after such default, this Agreement shall terminate without liability of any
party to any other party except that the provisions of Sections 6 and 9 hereof shall at all times be effective and shall survive such termination. In any such case either the Initial Purchasers or the Issuers shall have the right to postpone
the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Final Offering Memorandum or any other documents or arrangements may be effected. 

  
 32 







 (b) As used in this Agreement, the term “Initial Purchaser”
shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 12. Any action taken under this Section 12 shall not relieve any defaulting Initial Purchaser from liability in respect of any default
of such Initial Purchaser under this Agreement. 
 Section 13. 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 fourth paragraph and the tenth 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. 
 Section 14. Notices. All communications hereunder shall be in writing and,
if sent to the Initial Purchasers, shall be mailed or delivered to Merrill Lynch, Pierce, Fenner & Smith Incorporated at One Bryant Park, New York, New York 10036, Attention: High Yield Legal Department, Facsimile: (212) 901-7897; and if sent to the Partnership, shall be mailed or delivered to the Partnership at 1000 Louisiana Street, Suite 4300, Houston, Texas 77002, Attention: Chief Financial Officer; with a copy to
Vinson & Elkins L.L.P., 1001 Fannin Street, Suite 2500, Houston, Texas 77002, Attention: Christopher S. Collins. 

All such notices and communications shall be deemed to have been duly given: when delivered by hand, if personally delivered;
five business days after being deposited in the mail, postage prepaid, if mailed; and one business day after being timely delivered to a next-day air courier. 

Section 15. Successors. This Agreement shall inure to the benefit of and be binding upon the 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 under or in respect
of this Agreement, or any provisions herein contained; this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of such persons and for the benefit of no other person except that
(i) the indemnities of the Issuers contained in Section 9 of this Agreement shall also be for the benefit of the directors, officers and employees of the Initial Purchasers and any person or persons who control the Initial Purchasers
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and (ii) the indemnities of the Initial Purchasers contained in Section 9 of this Agreement shall also be for the benefit of the directors of the
Issuers, their officers and any person or persons who control the Issuers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act. No purchaser of Notes from the Initial Purchasers will be deemed a successor because
of such purchase. 
 Section 16. APPLICABLE LAW. THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT, ANY CLAIM,
COUNTERCLAIM OR DISPUTE OF ANY KIND OR NATURE WHATSOEVER ARISING OUT OF OR IN ANY WAY RELATING TO THIS AGREEMENT, DIRECTLY OR INDIRECTLY, AND THE TERMS AND CONDITIONS SET FORTH HEREIN SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED WHOLLY THEREIN, WITHOUT GIVING EFFECT TO ANY PROVISIONS THEREOF RELATING TO CONFLICTS OF LAW. 

  
 33

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 either of the Issuers, (iii) no
Initial Purchaser has assumed an advisory or fiduciary responsibility in favor of either 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 either of the Issuers on other matters) or any other obligation to the Issuers except the obligations expressly set forth in this Agreement and (iv) each of the Issuers has consulted its own legal and financial advisors to
the extent it deemed appropriate. Each of the Issuers agrees that it will not claim that any Initial Purchaser has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to either of the Issuers, in connection with
such transaction or the process leading thereto.

requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies their
respective clients, including the Issuers, which information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients.
