 Ladies and Gentlemen: 

Holly Energy Partners, L.P., a Delaware limited partnership (“Holly Energy Partners” or the
“Partnership”) and Holly Energy Finance Corp., a Delaware corporation (“Finance Corp.” and, together with Holly Energy Partners, the “Issuers”), and each of the Guarantors (defined herein)
agree with you as follows: 
 1. Issuance of Notes. The Issuers propose to issue and sell to Citigroup Global Markets
Inc., (the “Representative”) and the other initial purchasers listed on Schedule I hereto (together with the Representative, the “Initial Purchasers”) $400,000,000 in aggregate principal amount of 6.000%
Senior Notes due 2024 (the “Notes”). The Issuers’ obligations under the Notes and the Indenture (as defined below) will be, jointly and severally, unconditionally guaranteed (the “Guarantees” and, together with
the Notes, the “Securities”), on a senior basis, by each of the Subsidiaries (as defined below) listed on the signature pages hereto (each individually, a “Guarantor” and collectively, the
“Guarantors”). The Securities will be issued pursuant to an indenture (the “Indenture”), to be dated as of the Closing Date (as defined herein) by and among the Issuers, the Guarantors and U.S. Bank National
Association, as trustee (the “Trustee”). 
 The Securities will be offered and sold to the Initial Purchasers
pursuant to an exemption from the registration requirements under the Securities Act of 1933, as amended (the “Act”). The Issuers have prepared a preliminary offering memorandum, dated as of July 12, 2016 (the
“Preliminary Offering Memorandum”), and a pricing supplement thereto dated the date hereof (the “Pricing Supplement”). The Preliminary Offering Memorandum and the Pricing Supplement are herein referred to as the
“Pricing Disclosure Package.” Promptly after the execution of this Purchase Agreement (this “Agreement”), the Issuers will prepare a final offering memorandum dated the date hereof (the “Final Offering
Memorandum”). Unless stated to the contrary, any references herein to the terms “Pricing Disclosure Package” and “Final Offering Memorandum” shall be deemed to refer to and include any information filed under the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), prior to the date hereof and incorporated by reference therein, and any references herein to the terms “amend”, “amendment” or
“supplement” with respect to the Final Offering Memorandum shall be deemed to refer to and include any information filed under the Exchange Act subsequent to the date hereof that is incorporated by reference therein. All references in this
Agreement to financial statements and schedules  







 
and other information which is “contained,” “included” or “stated” (or other references of like import) in the Pricing Disclosure Package (including the Preliminary
Offering Memorandum) or Final Offering Memorandum shall be deemed to mean and include all such financial statements and schedules and other information which are incorporated by reference in the Pricing Disclosure Package or Final Offering
Memorandum, as the case may be. 
 The Initial Purchasers have advised the Issuers that the Initial Purchasers intend, as soon as
they deem practicable after this Agreement has been executed and delivered, to resell (the “Exempt Resales”) the Securities in private sales exempt from registration under the Act on the terms set forth in the Pricing Disclosure
Package, solely to (i) persons whom the Initial Purchasers reasonably believe to be “qualified institutional buyers” (“QIBs”), as defined in Rule 144A under the Act (“Rule 144A”), in accordance with
Rule 144A and (ii) other eligible purchasers pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Act (“Regulation S”) in accordance with Regulation S (the persons
specified in clauses (i) and (ii), the “Eligible Purchasers”). 
 This Agreement, the Notes and the
Indenture are hereinafter sometimes referred to collectively as the “Note Documents.” The issuance and sale of the Securities is referred to as the “Offering.” 

For the avoidance of doubt, references in this Agreement to the “Subsidiaries” (as defined below) shall be deemed to include
Finance Corp. and the Guarantors. 
 2. Agreements to Sell and Purchase. On the basis of the representations,
warranties and covenants contained in this Agreement, the Issuers and Guarantors agree to issue and sell to the Initial Purchasers, and on the basis of the representations, warranties and covenants contained in this Agreement, and subject to the

Partnership in accordance with Section 8(j) on or prior to the Closing Date, or by such means as the parties hereto shall agree prior to the Closing Date. The Securities shall be evidenced by one or more certificates in global form registered

Securities under any securities laws, and if at any time any securities commission or other regulatory authority shall issue an order suspending the qualification or exemption of any of the Securities under any securities laws, the Issuers shall use
their reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest possible time.

party to any indenture, mortgage, deed of trust, loan agreement or other agreement to which either Issuer or any Subsidiary is a party or by which any of them is bound or to which any of their respective properties is subject, is in default under
any such agreement, which breach, default or violation would, if continued, reasonably be expected to have a Material Adverse Effect. 

(xx) The execution, delivery and performance of this Agreement and the other Note Documents and the consummation of the
transactions contemplated hereby and thereby do not and will not (A) violate the certificate of limited partnership, agreement of limited partnership, certificate of formation, limited liability company agreement, certificate or articles of
incorporation, or bylaws of the Issuers or any Subsidiary, (B) conflict with or constitute a breach of or a default under (or an event that with notice or the lapse of time, or both, would constitute a default), any indenture, mortgage, deed of
trust, loan agreement, lease or other agreement or instrument to which either Issuer or any Subsidiary is a party or by which any of them or any of their respective properties may be bound, (C) violate any statute, law or regulation or any
order, judgment, decree or injunction of any court or governmental agency or body having authority over either Issuer or any Subsidiary or any of their properties in a proceeding to which any of them or their property is a party or (D) result
in the creation or imposition of any lien, charge or encumbrance upon any property or assets of either Issuer or any Subsidiary, which conflicts, breaches, violations or defaults, in the case of clauses (B), (C) or (D), would, individually or
in the aggregate, reasonably be expected to have a Material Adverse Effect.

 (xxi) No consent, approval, authorization, order, registration, filing or
qualification of or with any court, governmental agency or body is required for the offering, issuance and sale by the Issuers of the Notes, the issuance of the Guarantees by the Guarantors, the execution, delivery and performance of this Agreement
and the other Note Documents by the Issuers and the Guarantors or the consummation by the Issuers and the Guarantors of the transactions contemplated hereby or thereby, except (i) for such consents, approvals and similar authorizations required
under the Securities Act, the Exchange Act and state securities or “Blue Sky” laws, and (ii) for such consents which, if not obtained would not, individually or in the aggregate, reasonably be expected to have a Material Adverse
Effect. 
 (xxii) The public accountants whose reports appear or are incorporated by reference in the Offering
Memorandum are independent public accountants with respect to the Partnership within the meaning of Rule 101 of the Code of Professional Conduct of the American Institute of Certified Public Accountants and as required by the Public Company
Accounting Oversight Board (the “PCAOB”). The historical financial statements (including the notes thereto) included or incorporated by reference in the Offering Memorandum present fairly in all material respects the consolidated
combined financial position, results of operations, cash flows and changes in partner’s equity of the entities to which they relate at the respective dates and for the respective periods indicated. All such financial statements have been
prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) applied on a consistent basis throughout the periods presented (except as disclosed therein) and in compliance with Regulation S-X (“Regulation S-X”) under the Exchange Act, except that the interim financial statements do not include full footnote disclosure. The financial information
set forth under the captions “Summary – Summary Historical Financial and Operating Data” and “Selected Financial Data” included in or incorporated by reference in the Offering Memorandum has been prepared on a basis
consistent with that of the audited and unaudited financial statements from which it is derived.  
 (xxiii) Since the
date as of which information is given in the Offering Memorandum, except as set forth or contemplated in the Offering Memorandum, (A) neither Issuer nor any Subsidiary has (1) incurred any liabilities or obligations, direct or contingent,
that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect, or (2) entered into any material transaction not in the ordinary course of business and (B) except for the Partnership’s regular
distribution of $0.575 per unit, announced on April 22, 2016 and payable on May 13, 2016 to holders of record of the Partnership’s common units on May 2, 2016, there has been no dividend or distribution of any kind declared, paid
or made by the Partnership on any of its equity interests. The interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Offering Memorandum fairly presents the information called for in all material
respects and have been prepared in accordance with the Commission’s rules and guidelines applicable thereto. 
 (xxiv)
Except as set forth in the Offering Memorandum, there are no legal or governmental proceedings pending to which either Issuer or any Subsidiary is a party or of which any property of either Issuer or any Subsidiary is the subject which, if
determined adversely to such Issuer or Subsidiary, as the case may be, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect and, to the best knowledge of the Issuers and the Guarantors, no such proceedings
are threatened. 

  
 11 








 (xxv) No labor dispute with the employees of the Issuers or any Subsidiary exists
or, to the knowledge of the Issuers and the Guarantors, is imminent and the Issuers are not aware of any existing or imminent labor disturbance by the employees of any of their or the Subsidiaries’ principal suppliers, contractors or customers,
in each case, that is reasonably likely to result in a Material Adverse Effect. 
 (xxvi) Except as disclosed in the
Offering Memorandum, the Partnership and its Subsidiaries (i) are in compliance with any and all applicable foreign, federal, state and local laws and regulations relating to the protection of human health and safety and the environment or
imposing liability or standards of conduct, including the transport of, concerning any Hazardous Material (as defined below) (“Environmental Laws”), (ii) have received, and maintain in full force and effect, all Permits (as
defined below) required of them under applicable Environmental Laws to conduct their respective businesses, (iii) are in compliance with the terms and conditions of any such Permits, and (iv) to the knowledge of the Partnership, do not
have any liability in connection with either noncompliance with Environmental Laws or with the release into the environment of any Hazardous Materials, and (v) are not subject to any pending or, to the knowledge of the Partnership, threatened
claim or other legal proceeding under any Environmental Laws, except where such noncompliance with the Environmental Laws, failure to receive required Permits, failure to comply with the terms and conditions of such Permits or liability in
connection with such noncompliance, releases, claims or legal proceedings would not reasonably be expected to, individually or in the aggregate, have a Material Adverse Effect. The term “Hazardous Material” means (A) any
“hazardous substance” as defined in the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, (B) any “hazardous waste” as defined in the Resource Conservation and Recovery Act, as
amended, (C) any petroleum or petroleum product, (D) any polychlorinated biphenyl and (E) any pollutant or contaminant or hazardous, dangerous or toxic chemical, material, waste or substance regulated under or within the meaning of
any other Environmental Law. 
 (xxvii) In the ordinary course of its business, the Partnership periodically reviews
the effect of Environmental Laws on the business, operations and properties of the Partnership and its Subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or
operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the
basis of such review, the Partnership has concluded that such associated costs and liabilities as of the date hereof would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

(xxviii) Each of the Issuers and the Subsidiaries has such permits, consents, licenses, franchises, certificates and
authorizations of governmental or regulatory authority (“Permits”) as are necessary to own its properties and to conduct its business in the manner described in the Offering Memorandum, subject to such qualifications as may be set
forth in the Offering Memorandum (exclusive of any amendment or supplement thereto) and except for such Permits which, if not obtained, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; each of
the Issuers and the Subsidiaries has fulfilled and performed all its material obligations with respect to such Permits which are due to have been fulfilled and performed and no event has occurred which allows, or after notice or lapse of time would
allow, revocation or termination thereof or results in any impairment of the rights of the holder of any such Permit, except for such revocations, terminations and impairments that would not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect, subject in each case to such qualifications as may be set forth in the Offering Memorandum  

  
 12 








 
(exclusive of any amendment or supplement thereto); and except as described in the Offering Memorandum, none of the Permits contains any restriction that is materially burdensome to the
Partnership and the Subsidiaries, taken as a whole. 
 (xxix) The Operating Partnership and the other Subsidiaries
have such consents, easements, rights-of-way, permits or licenses from each person (collectively, “rights-of-way”) as are necessary to conduct its business in the manner described, and subject to the limitations contained, in the
Offering Memorandum, except for (A) qualifications, reservations and encumbrances which would not reasonably be expected to have a Material Adverse Effect upon the ability of the Partnership and its Subsidiaries, taken as a whole, to conduct
their businesses in all material respects as currently conducted and as contemplated by the Offering Memorandum to be conducted and (B) such rights-of-way that, if not obtained, would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect upon the ability of the Partnership and its Subsidiaries, taken as a whole, to conduct their businesses in all material respects as currently conducted and as contemplated by the Offering Memorandum to be
conducted; other than as set forth, and subject to the limitations contained, in the Offering Memorandum, each of the Partnership and its Subsidiaries has fulfilled and performed all its material obligations with respect to such rights-of-way and no
event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or would result in any impairment of the rights of the holder of any such rights-of-way, except for such revocations, terminations and
impairments that would not have a Material Adverse Effect upon the ability of the Partnership and its Subsidiaries, taken as a whole, to conduct their businesses in all material respects as currently conducted and as contemplated by the Offering
Memorandum to be conducted; and, except as described in the Offering Memorandum, none of such rights-of-way contains any restriction that is materially burdensome to the Partnership and its Subsidiaries, taken as a whole. 

(xxx) The Issuers and the Subsidiaries have filed (or have obtained extensions with respect to) all federal, state and foreign
income and franchise tax returns required to be filed through the date hereof, which returns are complete and correct in all material respects, and have timely paid all taxes shown to be due pursuant to such returns, other than those (A) which,
if not paid, would not reasonably be expected to have a Material Adverse Effect or (B) which are being contested in good faith and for which adequate reserves have been established in accordance with generally accepted accounting principles.

 (xxxi) There is and has been no failure on the part of the Partnership or any member, officer or director of the
Partnership, the General Partner or GP L.L.C., in their capacities as such, to comply in all material respects with any provision of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the
“Sarbanes-Oxley Act”), including Section 402 relating to loans and Sections 302 and 906 relating to certifications. 

(xxxii) None of the Partnership or any of its Subsidiaries nor, to the knowledge of the Partnership, any member,
officer, agent, employee or affiliate of the Partnership or any of its Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a violation or a sanction for violation by such persons of (i) the Foreign
Corrupt Practices Act of 1977, as amended, or the rules or regulations thereunder (the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance
of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the
FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA, (ii)  

  
 13 








 
the U.K. Bribery Act 2010, as amended, or the rules or regulations thereunder (together with the FCPA, the “Anti-Bribery Laws”) or (iii) any similar law of any other
relevant jurisdiction or the rules or regulations thereunder; the Partnership, the Subsidiaries and, to the knowledge of the Partnership, their affiliates, have conducted their businesses in compliance with the Anti-Bribery Laws and similar laws of
any other relevant jurisdiction and the rules and regulations thereunder, and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith; and no
part of the proceeds from the sale of the Securities will be used, directly or indirectly, in violation of the Anti-Bribery Laws or any similar law of any other relevant jurisdiction, or the rules or regulations thereunder.  

(xxxiii) The operations of the Partnership and its Subsidiaries are and have been conducted at all times in compliance
with applicable financial recordkeeping and reporting requirements and the money laundering statutes and the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any
governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Partnership or any of its
Subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Partnership, threatened. 

(xxxiv) Neither the Partnership nor any of its Subsidiaries nor, to the knowledge of the Partnership, any member,
officer, agent, employee or affiliate of the Partnership or any of its Subsidiaries (i) is, or is controlled or 50% or more owned by or is acting on behalf of, an individual or entity that is currently subject to any sanctions administered or
enforced by the United States (including any administered or enforced by the Office of Foreign Assets Control of the U.S. Treasury Department, the U.S. Department of State, or the Bureau of Industry and Security of the U.S. Department of Commerce)
or other relevant sanctions authority (collectively, “Sanctions” and such persons, “Sanctioned Persons”), (ii) is located, organized or resident in a country or territory that is, or whose government is, the
subject of Sanctions that broadly prohibit dealings with that country or territory (collectively, “Sanctioned Countries” and each a “Sanctioned Country”) or (iii) will directly or indirectly, use the proceeds
of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity for the purpose of financing the activities of any Sanctioned Person, or in any other manner that would
result in a violation of any Sanctions by, or could result in the imposition of Sanctions against, any individual or entity (including any individual or entity participating in the offering, whether as underwriter, advisor, investor or
otherwise). 
 (xxxv) Except as has been disclosed to the Initial Purchasers or is not material to the analysis under
any Sanctions, neither the Partnership nor any of the Subsidiaries has engaged in any dealings or transactions with or for the benefit of a Sanctioned Person, or with or in a Sanctioned Country, in the preceding 3 years, nor does the Partnership or
any of the Subsidiaries have any plans to increase its dealings or transactions with or for the benefit of Sanctioned Persons, or with or in Sanctioned Countries. 

(xxxvi) The statements set forth in the Offering Memorandum under the caption “Description of Notes”, insofar as they
purport to constitute a summary of the terms of the Notes, under the caption “Certain Material U.S. Federal Income Tax Considerations”, and under the caption “Plan of Distribution”, insofar as they purport to describe the
provisions of the laws and documents referred to therein, are accurate, complete and fair; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with
information furnished in writing to the Partnership by or on behalf of any Initial Purchaser through the Representative expressly for use therein. 

  
 14 








 (xxxvii) None of the Issuers or the Guarantors is, nor, after giving effect to
the Offering and the application of the proceeds thereof, will be, an “investment company” or a company “controlled by” an “investment company” as such terms are defined in the Investment Company Act of 1940, as
amended. 
 (xxxviii) The Partnership and the Subsidiaries maintain a system of internal control over financial reporting (as
such term is defined in Rule 13(a)-15(f) under the Exchange Act) that complies with the requirements of the Exchange Act and has been designed by the Partnership’s principal executive officer and principal financial officer, or under their
supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and that the interactive data
in eXtensible Business Reporting Language included or incorporated by reference in the Offering Memorandum fairly presents the information called for in all material respects and is prepared in accordance with the Commission’s rules and
guidelines applicable thereto. The Partnership’s internal control over financial reporting is effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles and the Partnership is not aware of any material weaknesses in its internal controls over financial reporting. 

(xxxix) Since the date of the latest audited financial statements included or incorporated by reference in the Offering
Memorandum, there has been no change in the Partnership’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

 (xl) The Partnership maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the
Exchange Act) that comply with the requirements of the Exchange Act; such disclosure controls and procedures have been designed to ensure that material information relating to the Partnership and the Subsidiaries is made known to the
Partnership’s principal executive officer and principal financial officer by others within those entities; and such disclosure controls and procedures are effective. 

(xli) The Issuers and the Subsidiaries maintain, or are entitled to the benefits of, insurance in such amounts and covering
such risks as the Issuers reasonably believe is adequate for the conduct of the business of the Partnership and the Subsidiaries. Neither the Partnership nor any of the Subsidiaries has received notice from any insurer or agent of such insurer that
substantial capital improvements or other expenditures will have to be made in order to continue such insurance, and all such insurance is outstanding and duly in force on the date hereof and will be outstanding and duly in force at Closing Date.

 (xlii) The Partnership is a partnership for U.S. federal income tax purposes. 

(xliii) The assumptions used in the preparation of the adjusted financial information included in the Offering Memorandum
(including “EBITDA” and “distributable cash flow”) are reasonable, and the adjustments used therein are appropriate to give effect to the transactions or circumstances referred to therein. 

  
 15 








 (xliv) No Subsidiary is currently prohibited, directly or indirectly, from paying
any dividends to the Partnership, from making any other distribution on such Subsidiary’s capital stock (or other ownership interests, as the case may be), from repaying to the Partnership any loans or advances to such Subsidiary from the
Partnership or from transferring any of such Subsidiary’s property or assets to the Partnership or any other Subsidiary, except as described in or contemplated in the Offering Memorandum. 

(xlv) Except as described in the section entitled “Plan of Distribution” in the Offering Memorandum, there are no
contracts, agreements or understandings between either Issuer or any Subsidiary and any other person other than the Initial Purchasers pursuant to this Agreement that would give rise to a valid claim against either Issuer, any Subsidiary or any of
the Initial Purchasers for a brokerage commission, finder’s fee or like payment in connection with the issuance, purchase and sale of the Securities. 

(xlvi) None of the Issuers, the Guarantors or any of their affiliates (as defined in Rule 501(b) of Regulation D under the Act)
has, directly or through any person acting on its or their behalf (other than any Initial Purchaser, as to which no representation is made), (A) taken, directly or indirectly, any action designed to, or that might reasonably be expected to,
cause or result in stabilization or manipulation of the price of any security of any Issuer to facilitate the sale or resale of the Securities, (B) sold, bid for, purchased or paid any person any compensation for soliciting purchases of the
Securities in a manner that would require registration of the Securities under the Act or paid or agreed to pay to any person any compensation for soliciting another to purchase any other securities of any Issuer in a manner that would require
registration of the Securities under the Act, (C) sold, offered for sale, contracted to sell, pledged, solicited offers to buy or otherwise disposed of or negotiated in respect of any security (as defined in the Act) that is currently or will
be integrated with the sale of the Securities in a manner that would require the registration of the Securities under the Act or (D) engaged in any directed selling effort (as defined by Regulation S) with respect to the Securities, and each of
them has complied with the offering restrictions requirement of Regulation S. 
 (xlvii) No form of general solicitation or
general advertising (prohibited by the Act in connection with offers or sales such as the Exempt Resales) was used by the Issuers or any person acting on its behalf (other than any Initial Purchaser, as to which no representation is made) in
connection with the offer and sale of any of the Securities or in connection with Exempt Resales, including, but not limited to, articles, notices or other communications published in any newspaper, magazine or similar medium or broadcast over
television or radio or the Internet, or any seminar or meeting whose attendees have been invited by any general solicitation or general advertising within the meaning of Regulation D under the Act. Neither the Issuers nor any of their
affiliates has entered into, or will enter into, any contractual arrangement with respect to the distribution of the Securities except for this Agreement. 

(xlviii) Neither the issuance, sale and delivery of the Securities nor the application of the proceeds thereof by the Issuers
as described in the Offering Memorandum will violate Regulation T, U or X of the Board of Governors of the Federal Reserve System or any other regulation of such Board of Governors. 

Each certificate signed by any officer of either Issuer or any Guarantor and delivered to the Initial Purchasers or counsel for the Initial
Purchasers pursuant to, or in connection with, this Agreement shall be deemed to be a representation and warranty by the Issuers and Guarantors to the Initial Purchasers as to the matters covered by such certificate. 

  
 16 








 The Issuers acknowledge that the Initial Purchasers and, for purposes of the opinions to be
delivered to the Initial Purchasers pursuant to Section 8 of this Agreement, counsel to the Partnership and counsel to the Initial Purchasers will rely upon the accuracy and truth of the foregoing representations and the Issuers hereby consent
to such reliance. 
 (b) Each Initial Purchaser represents that it is a QIB and acknowledges that it is purchasing the Securities pursuant
to a private sale exemption from registration under the Act, and that the Securities have not been registered under the 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 pursuant
to an exemption from the registration requirements of the Act. Each Initial Purchaser, severally and not jointly, represents, warrants and covenants to the Issuers and Guarantors that: 

(i) Neither it, nor any person acting on its behalf, has or will solicit offers for, or offer or sell, the Securities 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 it has and will solicit offers for the
Securities only from, and will offer and sell the Securities only to, (1) persons whom such Initial Purchaser reasonably believes to be QIBs or, if any such person is buying for one or more institutional accounts for which such person is acting
as fiduciary or agent, only when such person has represented to such Initial Purchaser that each such account is a QIB to whom notice has been given that such sale or delivery is being made in reliance on Rule 144A, and, in each case, in reliance on
the exemption from the registration requirements of the Act pursuant to Rule 144A, or (2) persons other than U.S. persons outside the United States in reliance on, and in compliance with, the exemption from the registration requirements of the
Act provided by Regulation S. 
 (ii) With respect to offers and sales outside the United States, such Initial Purchaser
has offered the Securities and will offer and sell the Securities (1) as part of its distribution at any time and (2) otherwise until 40 days after the later of the commencement of the offering of the Securities and the Closing Date, only
in accordance with Rule 903 of Regulation S or another exemption from the registration requirements of the Act. Accordingly, neither such Initial Purchasers nor any person acting on their behalf has engaged or will engage in any directed
selling efforts (within the meaning of Regulation S) with respect to the Securities, and any such persons have complied and will comply with the offering restrictions requirements of Regulation S. Terms used in this
Section 5(b)(ii) have the meanings given to them by Regulation S. 
 Each Initial Purchaser severally agrees that, at or prior
to confirmation of a sale of Securities pursuant to Regulation S it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it or through it during the restricted
period a confirmation or notice to substantially the following effect: 
 “The Securities covered hereby have not been
registered under the United States Securities Act of 1933, as amended (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 and (ii) otherwise until forty days after the later of the date upon which the offering of the Securities commenced and the date of closing, except in either case in accordance with Regulation S or Rule 144A under the
Securities Act. Terms used above have the meaning given to them by Regulation S.” 

  
 17 








 The Initial Purchasers understand that the Issuers and Guarantors and, for purposes of the
opinions to be delivered to them pursuant to Section 8 hereof, counsel to the Issuers and Guarantors and counsel to the Initial Purchasers will rely upon the accuracy and truth of the foregoing representations, and each Initial Purchaser hereby
consents to such reliance. 
 6. Indemnification. (a) The Issuers and Guarantors, jointly and severally, agree to indemnify and
hold harmless the Initial Purchasers, each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, the agents, employees, officers and directors of any
Initial Purchaser and the agents, employees, officers and directors of any such controlling person from and against any and all losses, liabilities, claims, damages and expenses whatsoever (including, but not limited, to reasonable attorneys’
fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all reasonable amounts paid in settlement of any claim or
litigation) (collectively, “Losses”) to which they or any of them may become subject under the Act, the Exchange Act or otherwise insofar as such Losses (or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the Pricing Disclosure Package, any Issuer Written Communication (including, but not limited to, any electronic roadshow), the Final Offering Memorandum, or in any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;
provided that none of the Issuers and Guarantors will be liable in any such case to the extent, but only to the extent, that any such Loss arises out of or is based upon any such untrue statement or alleged untrue statement or omission or
alleged omission relating to an Initial Purchaser made therein in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Initial Purchaser through the Representative expressly for use therein.
This indemnity agreement will be in addition to any liability that the Issuers and Guarantors may otherwise have, including, but not limited to, liability under this Agreement. 

(b) Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless the Issuers and Guarantors, and each person, if
any, who controls any of the Issuers and Guarantors within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, the agents, employees, officers and directors of any of the Issuers and Guarantors and of any such
controlling person from and against any and all Losses to which they or any of them may become subject under the Act, the Exchange Act or otherwise insofar as such Losses (or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the Pricing Disclosure Package or the Final Offering Memorandum, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact necessary 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 any such Loss arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged omission relating to such Initial Purchaser made therein in reliance upon and in conformity with information furnished in writing to the Partnership by or on behalf of such
Initial Purchaser through the Representative expressly for use therein. The Issuers and Guarantors and the Initial Purchasers acknowledge that the information described in Section 9 is the only information furnished in writing by the Initial
Purchasers to the Issuers expressly for use in the Preliminary Offering Memorandum or the Final Offering Memorandum. 
 (c) Promptly
after receipt by an indemnified party under subsection 6(a) or 6(b) above of notice of the commencement of any action, suit or proceeding (collectively, an “action”), such indemnified party shall, if a claim in respect
thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the commencement of such action (but the failure so to notify the indemnifying party will not
relieve it from  

  
 18 








 
liability under paragraph (a) or (b) above unless and to the extent it has been prejudiced in any material respect by such failure). In case any such action is brought against any
indemnified party, and it notifies an indemnifying party of the commencement of such action, the indemnifying party will be entitled to participate in such action, and to the extent it may elect by written notice delivered to the indemnified party
promptly after receiving the aforesaid notice from such indemnified party, to assume the defense of such action with counsel satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right
to employ its or their own counsel in any such action, but the reasonable fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in
writing by the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to take charge of the defense of such action within a reasonable time after notice of commencement
of the action, or (iii) the named parties to such action (including any impleaded parties) include such indemnified party and the indemnifying parties (or such indemnifying parties have assumed the defense of such action), and such indemnified
party or parties shall have reasonably concluded that there may be defenses available to it or them that are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not
have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such reasonable fees and expenses of counsel shall be borne by the indemnifying parties. In no event shall the indemnifying
parties be liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for all indemnified parties in connection with any one action or separate but substantially similar or related actions arising
in the same jurisdiction out of the same general allegations or circumstances. An indemnifying party shall not be liable for any settlement of any claim or action effected without its written consent, which consent may not be unreasonably withheld.
No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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 (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) does not include a
statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
 7.
Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 6 of this Agreement is for any reason held to be unavailable from the indemnifying party, or is insufficient
to hold harmless a party indemnified under Section 6 of this Agreement, each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such aggregate Losses (i) in such proportion as is
appropriate to reflect the relative benefits received by the Issuers and Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities or (ii) if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Issuers and Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the
statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be
deemed to be in the same proportion as (x) the total proceeds from the offering of Securities (net of discounts and commissions but before deducting expenses) received by the Issuers and Guarantors are to (y) the total discount and
commissions received by the Initial Purchasers. The relative fault of the Issuers and Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by an Issuer or the Initial Purchasers and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission or alleged statement or omission. 

  
 19 








 The Issuers and Guarantors and the Initial Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to above. Notwithstanding the provisions of
this Section 7, (i) in no case shall any Initial Purchaser be required to contribute any amount in excess of the amount by which the total discount and commissions applicable to the Securities purchased by such Initial Purchaser pursuant
to this Agreement exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission and (ii) 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. For purposes of this Section 7, each person, if any, who
controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each person, if any, who controls an Issuer or a
Guarantor within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and each director, officer, employee and agent of an Issuer or a Guarantor shall have the same rights to contribution as the Issuers and
Guarantors. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made against another party or parties under this
Section 7, notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may
have under this Section 7 or otherwise, but the failure so to notify the contributing party will not relieve it from liability under this Section 7 unless and to the extent it has been prejudiced in any material respect by such failure;
provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 6 for purposes of indemnification. Anything in this section to the contrary notwithstanding,
no party shall be liable for contribution with respect to any action or claim settled without its written consent; provided, however, that such written consent was not unreasonably withheld. The contribution obligations of the Initial
Purchasers under this Section 7 are several in proportion to their respective purchase obligations with respect to the Securities and not joint. 

8. Conditions of Initial Purchasers’ Obligations. The obligations of the Initial Purchasers to purchase and pay for the
Securities, as provided for in this Agreement, shall be subject to satisfaction of the following conditions prior to or concurrently with such purchase: 

(a) All of the representations and warranties of the Issuers and the Guarantors contained in this Agreement shall be true and
correct on the date of this Agreement and on the Closing Date. The Issuers and the Guarantors shall have performed or complied with all of the agreements and covenants contained in this Agreement and required to be performed or complied with by them
at or prior to the Closing Date. The Initial Purchasers shall have received a certificate, dated the Closing Date, signed by the Chief Financial Officer and Treasurer of the Issuers, certifying as to the foregoing and to the effect in
Section 8(c); 
 (b) The Final Offering Memorandum shall have been printed and copies distributed to the Initial
Purchasers as required by Section 4(b). No stop order suspending the qualification or exemption from qualification of the Securities in any jurisdiction shall have been issued and no proceeding for that purpose shall have been commenced or
shall be pending or threatened; 
 (c) Since the execution of this Agreement, there shall not have been any decrease in the
rating of any debt of the Issuers or any Subsidiary by any “nationally recognized statistical rating organization” (as defined in Section 3(a)(62) of the Exchange Act), or any notice given of any intended or potential decrease in any
such rating or of a possible change in any such rating that does not indicate the direction of the possible change; 

  
 20 








 (d) The Initial Purchasers shall have received on the Closing Date opinions dated
the Closing Date, addressed to the Initial Purchasers, of (i) Vinson & Elkins LLP, counsel to the Issuers and the Guarantors and (ii) Denise C. McWatters, general counsel of the Issuers and the Guarantors, substantially in the
form of Annex II(a) and Annex II(b) attached hereto; 
 (e) The Initial Purchasers shall have received on the
Closing Date an opinion dated the Closing Date of Latham & Watkins LLP, counsel to the Initial Purchasers, in form and substance satisfactory to the Representative. Such counsel shall have been furnished with such certificates and documents
as they may reasonably request to enable them to review or pass upon the matters referred to in this Section 8 and in order to evidence the accuracy, completeness or satisfaction in all material respects of any of the representations,
warranties or conditions contained in this Agreement; 
 (f) The Issuers, the Guarantors and the Trustee shall have executed
and delivered the Indenture and the Initial Purchasers shall have received copies thereof; 
 (g) On the date hereof, the
Initial Purchasers shall have received a “comfort letter” from the independent public accountants for the Partnership, dated the date of this Agreement, addressed to the Initial Purchasers and in form and substance satisfactory to the
Representative and counsel to the Initial Purchasers, covering the financial and accounting information in the Pricing Disclosure Package. In addition, the Initial Purchasers shall have received a
“bring-down comfort letter” from the independent public accountants for the Partnership, dated as of the Closing Date, addressed to the Initial Purchasers and in the form of the “comfort
letter” delivered on the date hereof, except that (i) it shall cover the financial and accounting information in the Final Offering Memorandum and any amendment or supplement thereto and (ii) procedures shall be brought down to a date
no more than 3 business days prior to the Closing Date, and otherwise in form and substance satisfactory to the Representative and counsel to the Initial Purchasers; 

(h) (i) Neither the Partnership nor any of its Subsidiaries shall have sustained since the date of the latest audited
financial statements included or incorporated by reference in the Final Offering Memorandum any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any court or
governmental action, order or decree, otherwise than as set forth or contemplated in the Final Offering Memorandum (exclusive of any amendment or supplement thereto), and (ii) since the respective dates as of which information is given in the
Final Offering Memorandum there shall not have been any change in the capital stock or long-term debt of the Partnership or any of its Subsidiaries or any change, or any development involving a prospective change, in or affecting the general
affairs, management, financial position, partners’ or stockholders’ equity or results of operations of the Partnership or any of its Subsidiaries, otherwise than as set forth or contemplated in the Final Offering Memorandum (exclusive of
any amendment or supplement thereto), the effect of which, in any such case described in clause (i) or (ii), is in your judgment so material and adverse as to make it impracticable or inadvisable to proceed with the offering or the delivery of
the Securities on the terms and in the manner contemplated in the Final Offering Memorandum (exclusive of any amendment or supplement thereto); 

(i) The Initial Purchasers shall have been furnished with written instructions for the application of the proceeds of the
Securities in accordance with this Agreement and such other information as they may reasonably request; and 

  
 21 








 (j) All agreements set forth in the blanket representation letter of the Issuers
to DTC relating to the approval of the Notes by DTC for “book-entry” transfer shall have been complied with. 
 If any of the
conditions specified in this Section 8 shall not have been fulfilled when and as required by this Agreement to be fulfilled (or waived by the Initial Purchasers), this Agreement may be terminated by the Initial Purchasers on notice to the
Issuers at any time at or prior to the Closing Date, and such termination shall be without liability of any party to any other party, except to the extent set forth in Section 11(d) hereof. 

The documents required to be delivered by this Section 8 will be delivered at the office of counsel for the Initial Purchasers on the
Closing Date. 
 9. Initial Purchasers Information. The Issuers, the Guarantors and the Initial Purchasers severally
acknowledge that, for all purposes (including Sections 5(a)(i) and 6), that (a) the statements relating to stabilization transactions and penalty bids set forth in the ninth and tenth paragraphs, and the fourth and fifth sentences of the eighth
paragraph, each under “Plan of Distribution” in the Preliminary Offering Memorandum and the Final Offering Memorandum and (b) the name and contact information of the Initial Purchasers in the Preliminary Offering Memorandum and the
Final Offering Memorandum, constitute the only information furnished in writing by or on behalf of any Initial Purchaser expressly for use in the Pricing Disclosure Package or the Final Offering Memorandum. 

10. Survival of Representations and Agreements. All representations and warranties, covenants and agreements contained in this
Agreement, including the agreements contained in Sections 4(f) and 11(d), the indemnity agreements contained in Section 6 and the contribution agreements contained in Section 7, shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of the Initial Purchasers or any controlling person thereof or by or on behalf of the Issuers, the Guarantors or any controlling person thereof, and shall survive delivery of and payment for the
Notes to and by the Initial Purchasers. The agreements contained in Sections 4(f), 6, 7, 9 and 11(d), and in Sections 13 through 19 shall survive the termination of this Agreement, including any termination pursuant to Sections 8, 11
or 12. 
 11. Effective Date of Agreement; Termination. (a) This Agreement shall become effective upon execution and
delivery of a counterpart hereof by each of the parties hereto. 
 (b) The Initial Purchasers shall have the right to terminate this
Agreement at any time prior to the Closing Date by notice to the Partnership from the Initial Purchasers, without liability (other than with respect to Sections 6 and 7) on the Initial Purchasers’ part to the Partnership or any affiliate
thereof if, on or prior to such date, (i) the Partnership shall have failed, refused or been unable to perform any agreement on its part to be performed under this Agreement when and as required; (ii) any other condition to the obligations
of the Initial Purchasers under this Agreement to be fulfilled by the Issuers and Guarantors pursuant to Section 8 is not fulfilled when and as required; (iii) trading in any securities of the Partnership shall be suspended or limited by
the Commission or the New York Stock Exchange, or trading in securities generally on the New York Stock Exchange, the NYSE MKT LLC or the Nasdaq Global Market shall have been suspended or materially limited, or minimum prices shall have been
established thereon by the Commission, or by such exchange or other regulatory body or governmental authority having jurisdiction; (iv) a general moratorium shall have been declared by either Federal or New York State authorities or a
material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred; (v) there is an outbreak or escalation of hostilities or national or international calamity in any case involving
the United States, on or after the date of this Agreement, or if there has been a declaration by the United States of a national 

  
 22 








 
emergency or war or other national or international calamity or crisis (economic, political, financial or otherwise) which affects the U.S. and international markets, making it, in the
Representative’s judgment, impracticable to proceed with the offering or delivery of the Securities on the terms and in the manner contemplated in the Pricing Disclosure Package; or (vi) there shall have been such a material adverse change
in general economic, political or financial conditions or the effect (or potential effect if the financial markets in the United States have not yet opened) of international conditions on the financial markets in the United States shall be such as,
in the Representative’s judgment, to make it inadvisable or impracticable to proceed with the offering or delivery of the Securities on the terms and in the manner contemplated in the Pricing Disclosure Package. 

(c) Any notice of termination pursuant to this Section 11 shall be given at the address specified in Section 13 below by telephone
or facsimile, confirmed in writing by letter. 
 (d) If this Agreement shall be terminated pursuant to Section 11(b)(i) or (ii), the
Issuers and Guarantors, jointly and severally, will reimburse the Initial Purchasers for all of their reasonable out-of-pocket expenses (including, without limitation,
the fees and expenses of the Initial Purchasers’ counsel) incurred in connection with this Agreement and the transactions contemplated hereby. 

12. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities
agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to
take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Notes set forth opposite the names of all the remaining
Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Notes which the defaulting
Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Notes set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall
not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the
Partnership. In the event of a default by any Initial Purchaser as set forth in this Section 12, the Closing Date shall be postponed for such period, not exceeding seven Business Days, as the Representative shall determine in order that the
required changes in the Final Offering Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Partnership or any
nondefaulting Initial Purchaser for damages occasioned by its default hereunder. 
 13. Notices. In all dealings hereunder,
you shall act on behalf of each of the Initial Purchasers, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Initial Purchaser made or given jointly by Citigroup Global Markets
Inc., as the Representative, except as otherwise provided herein. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Initial Purchasers shall be delivered or sent by mail or facsimile transmission to
(i) you as the Representative in care of Citigroup Global Markets Inc. at 388 Greenwich Street, New York, New York 10013, Facsimile: (212) 816-7912, Attention: General Counsel; and (ii) Latham & Watkins LLP, 885 Third Avenue,
New York, NY 10022 (fax number: 212-751-4864), Attention: Jonathan R. Rod, Esq.; and if sent to the Issuers and Guarantors, shall be mailed, delivered or telecopied and confirmed in writing to Holly Energy Partners, L.P., 2828 N. Harwood, Suite
1300, Dallas, Texas, 75201, (fax: 214-237-3051), Attention: Stephen D. Wise, Vice President and Treasurer, with a copy for information purposes only to Vinson & Elkins LLP, Trammell Crow Center, 2001 Ross Avenue, Suite 2700, Dallas, Texas
75201-2975, Attention: Alan Bogdanow, Esq. 

  
 23 








 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; when receipt acknowledged by telecopier machine, if telecopied; and one business day after being timely delivered to a next day air
courier. 
 In accordance with the 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 Partnership, 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. 
 14. Parties.
This Agreement shall inure solely to the benefit of, and shall be binding upon, the Initial Purchasers, the Issuers and Guarantors and the other indemnified parties referred to in Sections 6 and 7, and their respective successors and assigns, and no
other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Agreement or any provision herein contained. The term “successors and assigns” shall not include a
purchaser, in its capacity as such, of Securities from the Initial Purchasers. 
 15. CONSTRUCTION; GOVERNING LAW. THIS
AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO ANY PROVISIONS THEREOF RELATING TO CONFLICTS OF LAW). 

16. Submission to Jurisdiction; Waiver of Jury Trial. No proceeding related to this Agreement or the transactions contemplated hereby
may be commenced, prosecuted or continued in any court other than the courts of competent subject matter jurisdiction of the State of New York located in the City and County of New York or in the United States District Court for the Southern
District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Issuers and Guarantors hereby consent to the jurisdiction of such courts and personal service with respect thereto. The Issuers and Guarantors
hereby waive all right to trial by jury in any proceeding (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Issuers and Guarantors agree that a final judgment in any such proceeding brought
in any such court shall be conclusive and binding upon the Issuers and Guarantors and may be enforced in any other courts in the jurisdiction of which the Issuers and Guarantors are or may be subject, by suit upon such judgment. 

17. Captions. The captions included in this Agreement are included solely for convenience of reference and are not to be
considered a part of this Agreement. 
 18. Counterparts. This Agreement may be executed in various counterparts that together
shall constitute one and the same instrument. 
 19. No Fiduciary Relationship. The Issuers and Guarantors hereby acknowledge that
the Initial Purchasers are acting solely as initial purchasers in connection with the purchase and sale of the Securities. The Issuers and Guarantors further acknowledge that each of the Initial Purchasers is acting pursuant to a contractual
relationship created solely by this Agreement entered into on an arm’s length basis and in no event do the parties intend that any Initial Purchaser act or be responsible as a fiduciary to the Issuers and Guarantors, their management,
stockholders, creditors or any other person in connection with any activity that such Initial Purchaser may undertake or has undertaken in furtherance of the 

  
 24 








 
purchase and sale of the Securities, either before or after the date hereof. The Initial Purchasers hereby expressly disclaim any fiduciary or similar obligations to the Issuers and Guarantors,
either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Issuers and Guarantors hereby confirm their understanding and agreement to that effect. The Issuers and Guarantors and
each Initial Purchaser agree that they are each responsible for making their own independent judgments with respect to any such transactions, and that any opinions or views expressed by any Initial Purchaser to the Issuers and Guarantors regarding
such transactions, including but not limited to any opinions or views with respect to the price or market for the Securities, do not constitute advice or recommendations to the Issuers and Guarantors. The Issuers and Guarantors hereby waive and
release, to the fullest extent permitted by law, any claims that such Issuers and Guarantors may have against the Initial Purchasers with respect to any breach or alleged breach of any fiduciary or similar duty to the Issuers and Guarantors in
connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

(29) and (30) above, based on such counsel’s participation described above (relying with respect to factual matters to the extent such counsel deemed appropriate upon statements by officers and other representatives of the Issuers,
the Guarantors, the General Partner, or GP LLC), no facts have come to such counsel’s attention to cause such counsel to believe that any part of the Pricing Disclosure Package, as of July 13, 2016, or the Final Offering Memorandum, as of
its date and as of the date of this letter, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in light of the circumstances in which they were made,
not misleading; provided that such counsel need express no view, belief, or comment with respect to the financial statements and the other financial or accounting data included or incorporated by reference in or omitted from the Pricing Disclosure
Package or the Final Offering Memorandum.

FORM OF OPINION OF GENERAL COUNSEL FOR THE ISSUERS 

General Counsel Opinion 
 The
opinion of Denise C. McWatters, general counsel for the Issuers and the Guarantors (capitalized terms not otherwise defined herein shall have the meanings provided in the Purchase Agreement, to which this is an Annex), to be delivered pursuant to

 1. to the knowledge of such counsel, none of the offering,
issuance and sale by the Issuers and the Guarantors of the Securities, the execution, delivery and performance by each Issuer and each Guarantor of the Note Documents, or the consummation of the transactions contemplated thereby constitutes or will
constitute a breach or violation of, or a default under (or an event which, with notice or lapse of time or both, would constitute such a default), or require consent or waiver under any agreement or lease or other instrument to which either Issuer
or any Guarantor is a party or by which any of their respective properties may be bound, which breach, violation or default, or failure to acquire consent or waiver would, if continued, reasonably be expected to have a Material Adverse Effect (as
defined in the Purchase Agreement), other than such consents and waivers as have been obtained or will be obtained prior to the Closing Date and which, on the Closing Date, will be in full force and effect; 

2. to the knowledge of such counsel, none of the offering, issuance and sale by the Issuers and the Guarantors of the Securities, the
execution, delivery and performance by each Issuer and each Guarantor of the Note Documents to which it is a party, or the consummation of the transactions contemplated thereby constitutes or will constitute a breach or violation of, or a default
under (or an event which, with notice or lapse of time or both, would constitute such a default), or require consent or waiver under, any order, judgment, decree or injunction of any federal, Texas or Delaware court or government agency or body
directed to either Issuer or any Guarantor or any of their respective properties in a proceeding to which any of them or any such property is a party, which breach, violation or default would reasonably be expected to have a Material Adverse Effect;

 3. to the knowledge of such counsel, neither Issuer nor any Guarantor is in (i) violation of its certificate or agreement of limited
partnership, certificate of formation or limited liability company agreement, articles of incorporation or bylaws or other organizational documents, or (ii) violation of any law, statute, ordinance, administrative or governmental rule or
regulation applicable to it or of any decree of any court or governmental agency or body having jurisdiction over it, or in breach, default (or an event which, with notice or lapse of time or both, would constitute such a default) or violation in
the performance of any obligation, agreement or condition contained in any bond, debenture, note, or any other evidence of indebtedness or in any agreement, indenture, lease or other instrument to which it is a party or by which it or any of its
properties may be bound, which violation or breach, default or violation would, if continued, reasonably be expected to have a Material Adverse Effect; and 

4. to the knowledge of such counsel, there are no pending or threatened actions, suits or proceedings against or affecting either Issuer or
any Guarantor or any of their respective properties that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

In rendering such opinion, such counsel may (A) rely in respect of matters of fact upon information obtained from officers and employees
of GP L.L.C., the General Partner, the Partnership and the Subsidiaries and from public officials, (B) assume that all documents submitted to her as originals are authentic, that all copies submitted to her conform to the originals thereof, and
that the signatures on all 







 
documents examined by such counsel are genuine, (C) state that such counsel’s opinion is limited to federal laws, the DRULPA, the Delaware LLC Act, the DGCL, the TRLPA and the laws of
the State of Texas and (D) state that such counsel expresses no opinion with respect to state or local taxes or tax statutes.

and counsel for the Initial Purchasers, at which the contents of the Pricing Disclosure Package and the Final Offering Memorandum, and related matters, were discussed. Although such counsel is not passing upon and does not assume any responsibility
for or express any opinion regarding, the accuracy, completeness or fairness of the statements contained in the Pricing Disclosure Package and the Final Offering Memorandum, no facts have come to her attention to cause her to believe that any part
of the Pricing Disclosure Package, as of July 13, 2016, or the Final Offering Memorandum, as of its date and as of the date of this letter, contained or contains an untrue statement of a material fact or omitted or omits to state a material
fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided that such counsel need express no view, belief, or comment with respect to the financial statements and related schedules
and the other financial or accounting data included or incorporated by reference in or omitted from the Pricing Disclosure Package or the Final Offering Memorandum.
