 (jj) ERISA Compliance. Except as otherwise disclosed in the General Disclosure Package and the Final Offering Memorandum, the Company and its subsidiaries and any “employee benefit plan”
(as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974 (as amended, “ERISA,” which term, as used herein, includes the regulations and published interpretations thereunder) established or maintained
by the Company, its subsidiaries or their ERISA Affiliates (as defined below) are in compliance in all material respects with ERISA and, to the knowledge of the 

  
 11 








 
Company or the Guarantors, each “multiemployer plan” (as defined in Section 4001 of ERISA) to which the Company, its subsidiaries or an ERISA Affiliate contributes (a
“Multiemployer Plan”) is in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company or a subsidiary, any member of any group of organizations described in
Section 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986 (as amended, the “Code,” which term, as used herein, includes the regulations and published interpretations thereunder) of which the Company or such
subsidiary is or, within the last six years, has been a member. No “reportable event” (as defined in Section 4043 of ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan”
established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates. No “single employer plan” (as defined in Section 4001 of ERISA) established or maintained by the Company, its subsidiaries or any of their
ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined in Section 4001 of ERISA) that could, individually or in the aggregate (with any other
such “single employer plan”), reasonably be expected to result in a Material Adverse Effect. Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability (i) under
Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) that could, individually or in the aggregate, reasonably be expected to result in a Material Adverse Change under Sections 430,
4971, 4975 or 4980B of the Code. To the knowledge of the Company or the Guarantors, each “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified

(nn) Tax Returns. The Company and its subsidiaries have filed all federal, state, local and foreign tax returns

as would not, individually or in the aggregate, have a Material Adverse Effect.

Materials. The Company has not distributed and, prior to the Closing Date, will not distribute, any offering material in connection with the offering and sale of the Offered Securities other than the Preliminary Offering Memorandum, the Final
Offering Memorandum and any Issuer Free Writing Communication to which the Initial Purchaser has consented.

 (b) The Initial Purchaser acknowledges that the Offered Securities have not
been registered under the Securities Act and may 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 or pursuant to an exemption from the registration
requirements of the Securities Act. The Initial Purchaser represents and agrees that it has offered and sold the Offered Securities, and will offer and sell the Offered Securities (i) as part of its distribution at any time and
(ii) otherwise until 40 days after the later of the commencement of the offering and the Closing Date, only in accordance with Rule 903 or Rule 144A. Accordingly, neither the Initial Purchaser nor its affiliates, nor any persons acting on its
or their behalf, have engaged or will engage in any directed selling efforts with respect to the Offered Securities, and the Initial Purchaser, its affiliates and all persons acting on its or their behalf have complied and will comply with the
offering restrictions requirement of Regulation S. The Initial Purchaser agrees that, at or prior to confirmation of sale of the Offered Securities, other than a sale pursuant to Rule 144A, the Initial Purchaser will have sent to each distributor,
dealer or person receiving a selling concession, fee or other remuneration that purchases the Offered Securities from it during the restricted period a confirmation or notice to substantially the following effect: 

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933 (the “Securities Act”) and
may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the date of the commencement of the
offering and the closing date, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meanings given to them by Regulation S.” 

Terms used in this subsection (b) have the meanings given to them by Regulation S.

 15 








 (e) The Initial Purchaser represents and warrants and agrees that:

 (i) In relation to each Member State of the European Economic Area which has implemented the Prospectus

Date”), it has not made and will not make an offer of Offered Securities 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 Offered Securities

consent of the Initial Purchaser 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 Offered Securities to the public” in relation to any Offered Securities 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 Offered Securities to be offered so as to enable an investor to decide to purchase or subscribe for the Offered Securities, 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.

 (f) The Initial Purchaser acknowledges and agrees that the Company and the
Guarantors and, for purposes of the opinions to be delivered to the Initial Purchaser pursuant to Sections 7(c) and (d), counsel for the Company and the Guarantors and counsel for the Initial Purchaser, may rely upon the accuracy of the
representations and warranties of the Initial Purchaser, and compliance by the Initial Purchaser with its agreements, contained herein, and the Initial Purchaser hereby consents to such reliance. 

5. Certain Agreements of the Company and each Guarantor. The Company and each Guarantor agree with the Initial Purchaser that:

 (a) Amendments and Supplements to Offering Memoranda. The Company and the Guarantors will promptly
advise the Initial Purchaser of any proposal to amend or supplement the Preliminary Offering Memorandum or the Final Offering Memorandum and will not effect such amendment or supplementation without the Initial Purchaser’s consent. If, at any
time prior to the completion of the resale of the Offered Securities by the Initial Purchaser, there occurs an event or development as a result of which any document included in the Preliminary Offering Memorandum or the Final Offering Memorandum,
the General Disclosure Package or any Supplemental Marketing Material, if republished immediately following such event or development, included or would include an untrue statement of a material fact or omitted or would 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, the Company and the Guarantors promptly will notify the Initial Purchaser of such event and promptly will prepare
and furnish, at their own expense, to the Initial Purchaser and the dealers and to any other dealers at the request of the Initial Purchaser, an amendment or supplement which will correct such statement or omission. Neither the Initial
Purchaser’s consent to, nor the Initial Purchaser’s delivery to offerees or investors of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof. 

(b) Furnishing of Offering Memoranda. The Company and the Guarantors will furnish to the Initial Purchaser copies
of the Preliminary Offering Memorandum, each other document comprising a part of the General Disclosure Package, the Final Offering Memorandum, all amendments and supplements to such documents and each item of Supplemental Marketing Material, in
each case as soon as available and in such quantities as the Initial Purchaser requests. 
 (c) Blue Sky
Qualifications. The Company and the Guarantors will arrange for the qualification or registration of the Offered Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions in the United
States and Canada as the Initial Purchaser designates and will continue such qualifications or registrations in effect so long as required for the resale of the Offered Securities by the Initial Purchaser, provided that the Company and the
Guarantors will not be required to qualify as a foreign corporation or other entity, to file a general consent to service of process in any such jurisdiction, or subject themselves to taxation in any such jurisdiction where they are not then so
subject. 

  
 17 








 (d) Reporting Requirements. For so long as the Offered Securities
remain outstanding, the Company and the Guarantors will furnish to the Initial Purchaser, as soon as practicable after the end of each fiscal year, a copy of the Company’s annual report to stockholders for such year; and the Company and the
Guarantors will furnish to the Initial Purchaser (i) as soon as available, a copy of each report and any definitive proxy statement of the Company filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from
time to time, such other information concerning the Company and the Guarantors as the Initial Purchaser may reasonably request. However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d)
of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”), it is not required to furnish such reports or statements to the Initial Purchaser. At
any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company and the Guarantors will promptly furnish or cause to be furnished to the Initial Purchaser and, upon request of holders and prospective purchasers
of the Offered Securities, to such holders and purchasers, copies of the information required to be delivered to holders and prospective purchasers of the Offered Securities pursuant to Rule 144A(d)(4) (or any successor provision thereto) in order
to permit compliance with Rule 144A in connection with resales by such holders of the Offered Securities. The Company will pay the expenses of printing and distributing to the Initial Purchaser all such documents. 

(e) Transfer Restrictions. During the period of one year after the Closing Date, the Company will, upon request,
furnish to the Initial Purchaser and any holder of Offered Securities a copy of the restrictions on transfer applicable to the Offered Securities. 
 (f) No Resales by Affiliates. During the period of one year after the Closing Date, the Company will not, and will not permit any of its affiliates (as defined in Rule 144) to, resell any of the
Offered Securities that have been reacquired by any of them. 
 (g) Investment Company. During the period
of two years after the Closing Date or, if earlier, until such time as the Offered Securities are no longer “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, neither the Company nor any Guarantor will
be or become, an open-end investment company, unit investment trust or face-amount certificate company that is or is required to be registered under Section 8 of the Investment Company Act. 

(h) Payment of Expenses. The Company and the Guarantors will pay all expenses incidental to the performance of
their respective obligations under this Agreement, the Indenture and the Registration Rights Agreement, including but not limited to (i) the fees and expenses of the Trustee and its professional advisers; (ii) all expenses in connection
with the execution, issue, authentication, packaging and initial delivery of the Offered Securities and, as applicable, the Exchange Securities, the preparation and printing of this Agreement, the Registration Rights Agreement, the Offered
Securities, the Indenture, the Preliminary Offering Memorandum, any other documents comprising any part of the General Disclosure Package, the Final Offering Memorandum, all amendments and supplements thereto, each item of Supplemental


  
 18 








 
Marketing Material and any other document relating to the issuance, offer, sale and delivery of the Offered Securities and, as applicable, the Exchange Securities; (iii) the cost of any
advertising approved by the Company in connection with the issue of the Offered Securities; (iv) any expenses (including fees and disbursements of counsel to the Initial Purchaser) incurred in connection with qualification of the Offered
Securities or the Exchange Securities for sale under the laws of such jurisdictions in the United States and Canada as the Initial Purchaser designates and the preparation and printing of memoranda relating thereto; (v) any fees charged by
investment rating agencies for the rating of the Offered Securities or the Exchange Securities; and (vi) expenses incurred in distributing the Preliminary Offering Memorandum, any other documents comprising any part of the General Disclosure
Package, the Final Offering Memorandum (including any amendments and supplements thereto) and any Supplemental Marketing Material to the Initial Purchaser. The Company and the Guarantors will also pay or reimburse the Initial Purchaser (to the
extent incurred by the Initial Purchaser) for costs and expenses of the Initial Purchaser and the Company’s officers and employees and any other expenses of the Initial Purchaser and the Company and the Guarantors relating to investor
presentations on any “road show” in connection with the offering and sale of the Offered Securities including, without limitation, any travel expenses of the Company’s and the Guarantors’ officers and employees and any other
expenses of the Company and the Guarantors, provided, however, that the Initial Purchaser will pay fifty percent of the cost of any aircraft chartered in connection with the road show. For avoidance of doubt, except as provided in clause
(iv) above, the Initial Purchaser shall be responsible for its own counsel’s fees. 
 (i) Use of
Proceeds. The Company will use the net proceeds received in connection with this offering in the manner described in the “Use of Proceeds” section of the General Disclosure Package and the Final Offering Memorandum and, except as
disclosed in the General Disclosure Package and the Final Offering Memorandum, the Company does not intend to use any of the proceeds from the sale of the Offered Securities hereunder to repay any outstanding debt owed to any affiliate of the
Initial Purchaser. 
 (j) Absence of Manipulation. In connection with this offering, until the Initial
Purchaser shall have notified the Company of the completion of the resale of the Offered Securities, neither the Company, the Guarantors nor any of their affiliates will, either alone or with one or more other persons, bid for or purchase for any
account in which it or any of its affiliates has a beneficial interest any Offered Securities or attempt to induce any person to purchase any Offered Securities; and neither they nor any of their affiliates will make bids or purchases for the
purpose of creating actual, or apparent, active trading in, or of raising the price of, the Offered Securities. 

(k) Restriction on Sale of Securities. For a period of 60 days after the date hereof, neither the Company nor any
Guarantor will, directly or indirectly, offer, sell, issue, contract to sell, pledge or otherwise dispose of with respect to any United States dollar-denominated debt securities issued or guaranteed by the Company or such Guarantor and having a
maturity of more than one year from the date of issue, without the prior written consent of the Initial Purchaser. Neither the Company nor any 

  
 19 








 
Guarantor will at any time directly or indirectly, take any action referred to in the previous sentence with respect to any securities under circumstances where such offer, sale, pledge, contract
or disposition would cause the exemption afforded by Section 4(2) of the Securities Act or the safe harbor of Regulation S thereunder to cease to be applicable to the offer and sale of the Offered Securities. 

6. Free Writing Communications. 
 (a) Issuer Free Writing Communications. The Company and each Guarantor each represents and agrees that, unless it obtains the prior consent of the Initial Purchaser, and the Initial Purchaser
represents and agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Communication. 

(b) Term Sheets. The Company consents to the use by the Initial Purchaser of a Free Writing Communication that
(i) contains only (A) information describing the preliminary terms of the Offered Securities or their offering or (B) information that describes the final terms of the Offered Securities or their offering and that is included in or is
subsequently included in the Final Offering Memorandum, including by means of a pricing term sheet in the form of Exhibit A hereto, or (ii) does not contain any material information about the Company or any Guarantor or their
securities that was provided by or on behalf of the Company or any Guarantor, it being understood and agreed that the Company and each Guarantor shall not be responsible to the Initial Purchaser for liability arising from any inaccuracy in such Free
Writing Communications referred to in clause (i) or (ii) as compared with the information in the Preliminary Offering Memorandum, the Final Offering Memorandum or the General Disclosure Package. 

7. Conditions of the Obligations of the Initial Purchaser. The obligations of the Initial Purchaser to purchase and pay for the
Offered Securities will be subject to the accuracy of the representations and warranties of the Company and the Guarantors herein (as though made on the Closing Date), to the accuracy of the statements of officers of the Company and the Guarantors

Agreement, there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or otherwise), results of operations, business, properties or prospects of the Company and its
subsidiaries taken as a whole which, in the judgment of the Initial Purchaser, is material and adverse and makes it impractical or inadvisable to market the Offered Securities; (ii) any downgrading in the rating of any debt securities of the
Company or any Guarantor by any 

  
 20

of the Initial Purchaser, impractical to market or to enforce contracts for the sale of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market; (iv) any suspension or material limitation of
trading in securities generally on the New York Stock Exchange, or any setting of minimum or maximum prices for trading on such exchange; (v) or any suspension of trading of any securities of the Company or any Guarantor on any exchange or in

upon any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Offering Memorandum or the Final Offering Memorandum, in each case as amended or supplemented, or any Issuer Free Writing Communication or arise
out of or are based upon the omission or the alleged omission of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, 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 furnished to the Company by the Initial Purchaser specifically for use therein,
and will reimburse any legal or other expenses reasonably incurred by such Initial Purchaser Indemnified Party in connection with investigating, preparing or defending against any such loss, claim, damage, liability, action, litigation,
investigation or proceeding whatsoever (whether or not such Initial Purchaser Indemnified Party is a party thereto) whether threatened or commenced in connection with the enforcement of this provision with respect to any of the above as such
expenses are incurred, it being understood and agreed that the only such information furnished by the Initial Purchaser consists of the following information in the Preliminary and Final Offering


  
 23 








 
Memorandum: the second, ninth and tenth paragraphs under the caption “Plan of Distribution”; provided, however, that the Initial Purchaser shall not be liable for any losses, claims,
damages or liabilities arising out of or based upon the Company’s failure to perform its obligations under Section 5(a) of this Agreement. 
 (c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from
any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure
to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (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 satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes (i) an unconditional release of such indemnified party from all liability on any claims that are the subject matter
of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party. 

(d) Contribution. If the indemnification provided for in this Section 8 is unavailable or insufficient to hold
harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in
subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchaser on the other from the offering of the Offered Securities 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
Company and the Guarantors on the one hand and the Initial Purchaser on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations.
The relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchaser on the other shall be deemed to be in the same proportion as the total net 

  
 24 








 
proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Initial Purchaser from the Company under this Agreement.
The relative fault 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 Company
and the Guarantors or the Initial Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the
losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending
any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the total price at which
the Offered Securities purchased by it were resold exceeds the amount of any damages which the Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Company,
the Guarantors and the Initial Purchaser agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the
equitable considerations referred to in this Section 8(d). 
 9. Survival of Certain Representations and
Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Guarantors or their respective officers and of the Initial Purchaser set forth in or made pursuant to this Agreement will
remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Initial Purchaser, the Company, the Guarantors or any of their respective representatives, officers or directors or
any controlling person, and will survive delivery of and payment for the Offered Securities. If for any reason the purchase of the Offered Securities by the Initial Purchaser is not consummated, the Company and the Guarantors shall remain
responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company, the Guarantors and the Initial Purchaser pursuant to Section 8 shall remain in effect. If the purchase of the
Offered Securities by the Initial Purchaser is not consummated for any reason other than solely because of the occurrence of any event specified in clauses (iii), (iv), (vi), (vii) or (viii) of Section 7(b), the Company and the
Guarantors will reimburse the Initial Purchaser for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by the Initial Purchaser in connection with the offering of the Offered Securities. 

10. Notices. All communications hereunder will be in writing and, if sent to the Initial Purchaser will be mailed, delivered or
telegraphed and confirmed to the Initial Purchaser at RBC Capital Markets, LLC, Three World Financial Center, 200 Vesey Street, 10th Floor, New York, New York 10281-8098, Facsimile: (212) 618-2210, Attention: High Yield Capital Markets, or, if
sent to the Company or the Guarantors, will be mailed, delivered or telegraphed and confirmed to it at Three Allen Center, 333 Clay Street, Suite 4620, Houston, Texas 77002, Attention: Bradley J. Dodson. 

  
 25 








 11. Successors. This Agreement will inure to the benefit of and be binding upon the
parties hereto and their respective successors and the controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder, except that holders of Offered Securities shall be entitled to enforce the
agreements for their benefit contained in the second and third sentences of Section 5(b) hereof against the Company as if such holders were parties thereto. 
 12. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same
Agreement. 
 13. Absence of Fiduciary Relationship. The Company and the Guarantors acknowledge and agree that:

 (a) No Other Relationship. The Initial Purchaser has been retained solely to act as initial purchaser
in connection with the initial purchase, offering and resale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Company or the Guarantors and the Initial Purchaser has been created in respect of any of the
transactions contemplated by this Agreement or the Preliminary Offering Memorandum or the Final Offering Memorandum, irrespective of whether the Initial Purchaser has advised or is advising the Company or the Guarantors on other matters; 

(b) Arm’s-Length Negotiations. The purchase price of the Offered Securities set forth in this Agreement was
established by the Company and the Guarantors following discussions and arms-length negotiations with the Initial Purchaser and the Company and the Guarantors are capable of evaluating and understanding and understand and accept the terms, risks and
conditions of the transactions contemplated by this Agreement; 
 (c) Absence of Obligation to Disclose.
The Company has and the Guarantors have been advised that the Initial Purchaser and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company or the Guarantors and that the Initial
Purchaser has no obligation to disclose such interests and transactions to Company or the Guarantors by virtue of any fiduciary, advisory or agency relationship; and 

(d) Waiver. The Company and each Guarantor waive, to the fullest extent permitted by law, any claims it may have
against the Initial Purchaser for breach of fiduciary duty or alleged breach of fiduciary duty and agree that the Initial Purchaser shall have no liability (whether direct or indirect) to the Company or the Guarantors in respect of such a fiduciary
duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company or the Guarantors. 

14. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New
York. 

  
 26 








 The Company and the Guarantors hereby submit to the non-exclusive jurisdiction of the
Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company and the Guarantors irrevocably and
unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in The City of New York
and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

 Exhibit B 
 Form of Opinion of Vinson & Elkins L.L.P. 
 (a) Each of the
Company and each Guarantor is validly existing and in good standing as a corporation or other business entity under the laws of its jurisdiction of incorporation, organization or formation, as the case may be, with full power and authority
(corporate and other) necessary to own or lease its properties and to conduct its business, in each case as described in the General Disclosure Package and the Final Offering Memorandum in all material respects. Each of the Company and each
Guarantor is duly registered or qualified to do business as a foreign corporation or other business entity, as the case may be, in good standing under the laws of each jurisdiction set forth opposite its name on Exhibit A to such opinion.

 (b) Each of the Company and each Guarantor has all requisite corporate, limited liability company, or limited partnership
power and authority to execute, deliver and perform its obligations under the Purchase Agreement, the Indenture, the Offered Securities and the Exchange Securities to which it is a party and to consummate the transactions contemplated thereby. The
Purchase Agreement has been duly executed and delivered by the Company. 
 (c) The Indenture has been duly and validly
authorized, executed and delivered by the Company and each of the Guarantors and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes the valid and legally binding agreement of the Company and each of the
Guarantors, enforceable against them in accordance with its terms, except that the enforcement thereof may be subject to the Enforceability Exceptions. 
 (d) The Offered Securities have been duly and validly authorized and executed by the Company and, when the Offered Securities are duly executed, issued and delivered by the Company and, when authenticated
in accordance with the provisions of the Indenture and delivered to and paid for by the Initial Purchaser pursuant to the Purchase Agreement on the Closing Date (assuming the due authorization, execution and delivery of the Indenture by the Trustee
and due authentication and delivery of the Offered Securities by the Trustee in accordance with the Indenture), such Offered Securities will constitute the valid and legally binding obligations of the Company, entitled to the benefits of the
Indenture, and enforceable against the Company in accordance with their terms, subject to the Enforceability Exceptions. 
 (e)
The Guarantee endorsed on the Offered Securities by each Guarantor has been duly and validly authorized and executed by such Guarantor and, when the Offered Securities are delivered to and paid for by the Initial Purchaser pursuant to the Purchase
Agreement on the Closing Date (assuming the due authorization, execution and delivery of the Indenture by the Trustee and due authentication and delivery of the Offered Securities by the Trustee in accordance with the Indenture), the Guarantee of
each Guarantor endorsed thereon will constitute valid and legally binding obligations of such Guarantor, entitled to the benefits of the Indenture, and enforceable in accordance with its terms, subject to the Enforceability Exceptions. 

(f) The Registration Rights Agreement has been duly authorized, executed and delivered by the Company and the Guarantors and, assuming
the due authorization, execution and delivery thereof by the Initial Purchaser, constitutes the valid and legally binding obligations

 (g) No consent, approval, authorization, or order of, or
filing or registration with, any person (including any governmental agency or body or any court) is required for the execution, delivery and performance of the Purchase Agreement by the Company and the Guarantors, the consummation of the
transactions contemplated by the Purchase Agreement, the Indenture and the Registration Rights Agreement in connection with the offering, issuance and sale of the Offered Securities and the Guarantees by the Company and the Guarantors, and the
application of the proceeds from the sale of the Offered Securities by the Company as described under “Use of Proceeds” in the General Disclosure Package and the Final Offering Memorandum, except for, (i) if required, the order of the
Commission declaring effective the Exchange Offer Registration Statement or, if required, the Shelf Registration Statement (each as defined in the Registration Rights Agreement), (ii) if required, the qualification of the Indenture under the
Trust Indenture Act in connection with the issuance of the Exchange Notes, (iii) such as have previously been obtained and (iv) applicable federal, state or foreign securities laws in connection with the purchase and sale of the Offered
Securities by the Initial Purchaser as to which such counsel need express no opinion other than the opinion provided in paragraph (j) below.

of the Offered Securities and the Guarantees by the Company and the Guarantors and compliance with the terms and provisions thereof, and the application of the proceeds from the sale of the Offered Securities by the Company as described under
“Use of Proceeds” in the General Disclosure Package and the Final Offering Memorandum will not (i) result in a breach or violation of any of the terms or provisions of, or constitute a default or a Debt Repayment Triggering Event
under, or result in the imposition of any lien, charge or encumbrance upon any property or assets of the Company or its subsidiaries pursuant to, any instrument to which the Company is a party and which is filed as an exhibit and set forth on the

 Exhibit B-2








 (i) Neither the Company nor any Guarantor is, after giving effect to the offering and sale
of the Offered Securities and the application of the proceeds thereof as described in the General Disclosure Package and the Final Offering Memorandum, will be, an “investment company” within the meaning of such term under the Investment
Company Act. 
 (j) Assuming the accuracy of the representations, warranties and agreements of the Company, the Guarantors and
the Initial Purchaser contained in the Purchase Agreement, (A) no registration under the Securities Act of the Offered Securities is required in connection with the sale of the Offered Securities to the Initial Purchaser or in connection with
the initial resale of the Offered Securities by the Initial Purchaser, in each case as contemplated by the Purchase Agreement, the General Disclosure Package and the Final Offering Memorandum, and (B) prior to the commencement of the Exchange
Offer or the effectiveness of any registration statement prepared in connection with the Company’s obligations under the Registration Rights Agreement, the Indenture is not required to be qualified under the Trust Indenture Act. 

(k) The statements in the General Disclosure Package and the Final Offering Memorandum under the captions “Description of the
Notes,” “Description of Other Indebtedness,” and “Certain United States Federal Income Tax Consequences”, insofar as such statements summarize legal matters, agreements, documents or proceedings discussed therein, have been
reviewed by us and are accurate in all material respects. 
 In addition, such counsel shall also state that it has participated
in conferences with representatives of the Company and with representatives of its independent registered public accounting firm at which conferences the contents of the General Disclosure Package and the Final Offering Memorandum and related
matters were discussed. Although such counsel has not undertaken to determine independently, and does not assume any responsibility for, or express any opinion regarding the accuracy, completeness or fairness of the statements contained in the
General Disclosure Package or the Final Offering Memorandum (except as expressly provided above), based upon the participation described above, nothing has come to the attention of such counsel to cause such counsel to believe that the General
Disclosure Package, as of the Applicable Time, or that the Final Offering Memorandum, as of its date or at the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make
the statements therein, in the light of the circumstances under which they were made, not misleading. In making the foregoing statement, such counsel need not express any comment or belief with respect to the financial statements and notes and
related schedules and other financial and accounting data contained in or omitted from the General Disclosure Package or the Final Offering Memorandum.
