RECITALS 
 WHEREAS, the
Borrower, the Company, the Lenders and Bank of America, N.A., as Agent and as the Issuing Bank and as Swing Line Bank have entered into that certain Credit Agreement dated as of July 28, 2014 (as amended or modified from time to time, the
“Credit Agreement”); 
 WHEREAS, in connection with the Credit Agreement, the Company and the other Guarantors have each
executed and delivered in favor of the Agent and the Lenders a certain Guaranty pursuant to which the Company and the other Guarantors have guaranteed the Borrower’s obligations under the Credit Agreement; 

WHEREAS, the Borrower has requested that the Lenders agree to amend the Credit Agreement as described below; 

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1. Amendments.
Subject to the satisfaction of the conditions set forth in Section 2 hereof, the Credit Agreement is hereby amended as follows: 

(a) Section 1.01 of the Credit Agreement is hereby amended to restate the proviso at the end of the definition of
“Eurodollar Rate” in its entirety to read as follows: 
 “provided that (i) to the
extent a comparable or successor rate is approved by the Agent in connection with any rate set forth in this definition, the approved rate shall be applied in a manner consistent with market practice; provided, further that to the extent such market
practice is not administratively feasible for the Agent, such approved rate shall be applied in a manner as otherwise reasonably determined by the Agent and (ii) if the Eurodollar Rate shall be less than zero, such rate shall be deemed zero for
purposes of this Agreement.” 
 (b) Section 1.01 of the Credit Agreement is hereby amended to restate the
definition of “Obligations” in its entirety to read as follows: 
 ““Obligations”
means all advances to, and debts, liabilities, obligations, covenants and duties of, the Borrower or the Company arising under any Loan Document or otherwise with respect to any Loan or Letter of Credit, whether direct or indirect (including those
acquired by assignment), absolute or contingent, due or to become due, now existing or hereafter arising and including (i) interest and fees that accrue after the commencement by or against the Borrower or any Guarantor or any Affiliate thereof
of any Insolvency Proceeding naming such Person as the debtor in such Insolvency Proceeding regardless of whether such interest and fees are allowed claims in such Insolvency Proceeding and (ii) obligations of the Borrower or the Company under
any Swap Contract to which a Lender or any Affiliate of a Lender is a party; provided that the Obligations shall exclude any Excluded Swap Obligations.” 

 (c) Section 2.03 of the Credit Agreement is hereby amended to replace all
references to “11:00 a.m.” contained in the first sentence of clause (a) thereof with “1:00 p.m.”. 

(d) Section 2.04 of the Credit Agreement is hereby amended to replace all references to “11:00 a.m.” contained
in clause (b) thereof with “1:00 p.m.”. 
 (e) Section 2.06 of the Credit Agreement is hereby amended to
replace the reference to “11:00 a.m.” contained therein with “1:00 p.m.”. 
 (f) Clause (c) of
Section 2.07 of the Credit Agreement is hereby amended and restated in its entirety to read as follows: 
 “(c)
General. Any prepayments pursuant to this Section 2.07 shall be applied first to any Base Rate Loans then outstanding, then to Eurodollar Rate Loans with the shortest Interest Periods remaining and then to any amounts due under
any Swap Contract between the Company or the Borrower and any Lender, or any Affiliate of a Lender, ratably among the Lenders (and, in the case of such Swap Contracts, Affiliates of Lenders); provided that if due to a Defaulting Lender’s
failure to fund any requested Borrowing, there are Non-Ratable Loans outstanding at the time of any prepayment, such prepayment shall be applied first to Non-Ratable Loans and then in accordance with the foregoing order. The Borrower shall pay,
together with each prepayment under this Section 2.07, accrued interest on the amount prepaid and any amounts required pursuant to Section 4.04.” 

(g) Clause (d) of Section 2.15 of the Credit Agreement is hereby amended and restated in its entirety to read as
follows: 
 “(d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting
Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable
Lender (or, as appropriate, its assignee following compliance with Section 11.08(g))) or (ii) the Agent’s good faith determination that there exists excess Cash Collateral; provided, however, (x) that Cash Collateral
furnished by or on behalf of the Borrower shall not be released during the continuance of a Default or Event of Default (and following application as provided in this Section 2.15 may be otherwise applied in accordance with
Section 9.04 during the continuance of an Event of Default), and (y) the Person providing Cash Collateral and the Issuing Bank or Swing Line Bank, as applicable, may agree that Cash Collateral shall not be released but instead held
to support future anticipated Fronting Exposure or other obligations.” 
 (h) Section 3.02 of the Credit
Agreement is hereby amended to replace the reference to “11:00 a.m.” contained therein with “1:00 p.m.”. 

(i) Section 4.01 of the Credit Agreement is hereby amended to add the following new clause (g) immediately at the end
of the existing clause (f) thereof: 
 “(g) For purposes of determining withholding Taxes imposed under FATCA,
from and after October 16, 2015, the Borrower and the Agent shall treat (and the Lenders hereby authorize the Agent to treat) this Agreement as not qualifying as a “grandfathered obligation” within the meaning of Treasury Regulation
Section 1.1471-2(b)(2)(i).” 

 (j) Article IX of the Credit Agreement is hereby amended to add the following new
Section 9.04 immediately at the end of the existing Section 9.03 thereof: 
 “9.04 Application of
Funds. After the exercise of remedies provided for in Section 9.02 (or after the Loans have automatically become immediately due and payable and the L/C Obligations have automatically been required to be Cash Collateralized as set
forth in the proviso to Section 9.02), any amounts received on account of the Obligations shall, subject to the provisions of Sections 2.15 and 2.16, be applied by the Agent in the following order: 

First, to payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts (including fees,
charges and disbursements of counsel to the Agent and amounts payable under Article IV) payable to the Agent in its capacity as such; 

Second, to payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts (other than
principal, interest and Letter of Credit Fees) payable to the Lenders and the Issuing Bank (including fees, charges and disbursements of counsel to the respective Lenders and the Issuing Bank and amounts payable under Article IV),
ratably among them in proportion to the amounts described in this clause Second payable to them; 
 Third, to payment of
that portion of the Obligations constituting accrued and unpaid Letter of Credit Fees and interest on the Loans and L/C Borrowings and fees, premiums and scheduled periodic payments, and any interest accrued thereon, due under any Swap Contract
between the Company or the Borrower and any Lender, or any Affiliate of a Lender, ratably among the Lenders (and, in the case of such Swap Contracts, Affiliates of Lenders) and the Issuing Bank in proportion to the respective amounts described in
this clause Third payable to them; 
 Fourth, to payment of that portion of the Obligations constituting unpaid
principal of the Loans and L/C Borrowings, payment of breakage, termination or other payments, and any interest accrued thereon, due under any Swap Contract between the Company or the Borrower and any Lender, or any Affiliate of a Lender, ratably
among the Lenders (and, in the case of such Swap Contracts, Affiliates of Lenders) and the Issuing Bank in proportion to the respective amounts described in this clause Fourth held by them; 

Fifth, to the Agent for the account of the Issuing Bank, to Cash Collateralize that portion of L/C Obligations comprised of the
aggregate undrawn amount of Letters of Credit to the extent not otherwise Cash Collateralized by the Borrower pursuant to Article III, Section 2.07 and/or 2.15; and 

Last, the balance, if any, after all of the Obligations have been indefeasibly paid in full, to the Borrower or as otherwise a
Requirement of Law. 
 Subject to Article III and Section 2.15, amounts used to Cash Collateralize the aggregate
undrawn amount of Letters of Credit pursuant to clause Fifth above shall be applied to satisfy drawings under such Letters of Credit as they occur. If any amount remains on deposit as Cash Collateral after all Letters of Credit have either
been fully drawn or expired, such remaining amount shall be applied to the other Obligations, if any, in the order set forth above. Excluded Swap Obligations with respect to any Guarantor shall not be paid with amounts received from such Guarantor
or its assets, but appropriate adjustments shall be made with respect to payments from other Guarantors to preserve the allocation to Obligations otherwise set forth above in this Section.” 

 (k) Section 10.10 of the Credit Agreement is hereby amended and restated in
its entirety to read as follows: 
 “10.10 Guaranty Matters. The Lenders irrevocably authorize the Agent, at
its option and in its discretion to release any Guarantor from its obligations under the Guaranty if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder. Upon request by the Agent at any time, the Majority Lenders
will confirm in writing the Agent’s authority to release any Guarantor from its obligations under the Guaranty pursuant to this Section 10.10. Except as otherwise expressly set forth herein, no Lender or Affiliate of a Lender in its
capacity as a party to a Swap Contract with the Borrower or the Company that obtains the benefit of the provisions of Section 9.04 or the Guaranty by virtue of the provisions hereof or any other Loan Document shall have any right to notice of
any action or to consent to, direct or object to any action hereunder or under any other Loan Document (including notice of or to consent to any amendment, waiver or modification of the provisions hereof or of the Guaranty or any other Loan
Document) other than in its capacity as a Lender and, in such case, only to the extent expressly provided in the Loan Documents. Notwithstanding any other provision of this Article X to the contrary, the Agent shall not be required to verify the
payment of, or that other satisfactory arrangements have been made with respect to, Obligations arising under Swap Contracts except to the extent expressly provided herein. The Agent shall not be required to verify the payment of, or that other
satisfactory arrangements have been made with respect to, Obligations arising under Swap Contracts in the case of the Revolving Termination Date.” 

(l) Clause (e) of Section 11.01 of the Credit Agreement is hereby amended and restated in its entirety to read as
follows: 
 “(e) change Section 2.14 or Section 9.04 in a manner that would alter the pro rata sharing of
payments required thereby without the written consent of each Lender;” 
 (m) Clause (f) of Section 11.08
of the Credit Agreement is hereby amended to restate the proviso at the end thereof in its entirety to read as follows: 

“provided that notwithstanding anything contained herein to the contrary the Agent is under no obligation to agree to
accept electronic signatures in any form or in any format unless expressly agreed to by the Agent pursuant to procedures approved by it; provided further without limiting the foregoing, upon the request of the Agent, any electronic signature shall
be promptly followed by such manually executed counterpart.” 
 2. Condition Precedent. This Agreement shall
be effective upon receipt by the Agent of counterparts of this Agreement duly executed by the Borrower, the Company, the other Guarantors and the Lenders. 

3. Miscellaneous. 

(a) The Credit Agreement, and the obligations of the Borrower, the Company and each Guarantor thereunder and under the other
Loan Documents, are hereby ratified and confirmed and shall remain in full force and effect according to their terms. This Agreement shall constitute a Loan Document. 

(b) The Company and each other Guarantor, (i) acknowledges and consents to all of the terms and conditions of this
Agreement, (ii) affirms all of each Guarantor’s obligations under the Loan Documents (as amended hereby) and (iii) agrees that this Agreement and all documents executed in 

 
connection herewith do not operate to reduce or discharge each Guarantor’s obligations under the Credit Agreement (as amended hereby) or the Loan Documents. 

(c) The Borrower and the Company hereby represent and warrant as follows: 

(i) Each of the Borrower and the Company has taken all necessary action to authorize the execution, delivery and performance
of this Agreement. 
 (ii) This Agreement has been duly executed and delivered by the Company and the Borrower and
constitutes each of the Borrower’s and the Company’s legal, valid and binding obligations, enforceable in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, or similar laws
affecting the enforcement of creditors’ rights generally or by equitable principles relating to enforceability, regardless of whether considered in a proceeding in equity or at law. 

(iii) No consent, approval, exemption, authorization or other action by, or notice to, or filing with, any Governmental
Authority or any other Person is necessary or required in connection with the execution, delivery or performance by the Borrower or the Company of this Agreement. 

(d) Each of the Borrower and the Company represents and warrants to the Lenders that (i) its representations and
warranties set forth in Article VI of the Credit Agreement and in each other Loan Document are true and correct in all material respects (and in all respects if any such representation or warranty is already qualified by materiality) as of the date
hereof with the same effect as if made on and as of the date hereof, except to the extent such representations and warranties expressly relate solely to an earlier date, in which case they shall be true and correct in all material respects (and in
all respects if any such representation or warranty is already qualified by materiality) as of such earlier date and (ii) no event has occurred and is continuing which constitutes a Default or an Event of Default. 

(e) This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be an
original, but all of which shall constitute one and the same instrument. Delivery of an executed counterpart of this Agreement by telecopy or other electronic transmission shall be effective as an original and shall constitute a representation that
an executed original shall be delivered. 
 (f) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND ANY CLAIMS, CONTROVERSY,
DISPUTE OR CAUSE OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT (EXCEPT, AS TO ANY OTHER LOAN DOCUMENT, AS EXPRESSLY SET FORTH THEREIN) AND THE TRANSACTIONS
CONTEMPLATED HEREBY AND THEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK (INCLUDING SECTIONS 5-1401 AND 5-1402 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK BUT OTHERWISE WITHOUT REGARD TO
THE CONFLICT OF LAW PRINCIPLES THEREOF WHICH WOULD RESULT IN THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION).

(d) The Indemnifying Party shall not be entitled to control (but shall be entitled to participate at its own expense in the defense of), and
the Indemnified Party shall be entitled to have sole control over, the defense or settlement, compromise, admission, or acknowledgment of any third-party action (i) as to which the Indemnifying Party fails to assume the defense within a
reasonable length of time or (ii) to the extent the third-party action seeks an order, injunction, or other equitable relief against the Indemnified Party which, if successful, would materially adversely affect the business, operations, assets,
or financial condition of the Indemnified Party; provided, however, that the Indemnified Party shall make no settlement, compromise, admission, or acknowledgment that would give rise to liability on the part of any Indemnifying Party without the

hereof. Subject to the limitations set forth in Section 9.4(a), the failure of the Indemnified Party to exercise promptness in such notification shall not amount to a waiver of such claim unless the resulting delay materially prejudices
the position of the Indemnifying Party with respect to such claim.

 (b) Any Party may at any time change its address for service from time to time by giving notice
to the other Parties in accordance with this Section 10.2. 
 10.3. Severability. If any term or other provision of this
Agreement is invalid, illegal, or incapable of being enforced under Applicable Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance
of the transactions contemplated herein are not affected in any manner adverse to any Party. Upon such determination that any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced, the Parties shall negotiate
in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated herein are consummated as originally contemplated to the
fullest extent possible. 
 10.4. Governing Law; Jurisdiction; Waiver of Jury Trial. This Agreement shall be subject to and governed
by the laws of the State of Delaware, excluding any conflicts-of-law rule or principle that might refer the construction or interpretation of this Agreement to the laws of another state. Each Party hereby submits to the jurisdiction of the state and
federal courts in the State of Texas and to venue in Dallas, Texas. EACH OF THE PARTIES IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY. 
 10.5. Arbitration Provision. Any and all Arbitrable Disputes must be resolved through the use of binding arbitration using
three arbitrators, in accordance with the Commercial Arbitration Rules of the American Arbitration Association, as supplemented to the extent necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the
United States Code). If there is any inconsistency between this Section 10.5 and the Commercial Arbitration Rules or the Federal Arbitration Act, the terms of this Section 10.5 will control the rights and obligations of
the Parties. Arbitration must be initiated within the time limits set forth in this Agreement, or if no such limits apply, then within a reasonable time or the time period allowed by the applicable statute of limitations. Arbitration may be
initiated by a Party (“Claimant”) serving written notice on the other Party (“Respondent”) that the Claimant elects to refer the Arbitrable Dispute to binding arbitration. Claimant’s notice initiating binding
arbitration must identify the arbitrator Claimant has appointed. The Respondent shall respond to Claimant within thirty (30) days after receipt of Claimant’s notice, identifying the arbitrator Respondent has appointed. If the
Respondent fails for any reason to name an arbitrator within the 30-day period, Claimant shall petition the American Arbitration Association for appointment of an arbitrator for Respondent’s account. The
two arbitrators so chosen shall select a third arbitrator within thirty (30) days after the second arbitrator has been appointed. The Claimant will pay the compensation and expenses of the arbitrator named by it, and the Respondent will pay the
compensation and expenses of the arbitrator named by or for it. The costs of petitioning for the appointment of an arbitrator, if any, shall be paid by Respondent. The Claimant and Respondent will each pay one-half of the compensation and expenses
of the third arbitrator. All arbitrators must (i) be neutral parties who have never been officers, directors or employees of Seller, Buyer or any of their Affiliates and (ii) have not less than seven (7) years’ experience in the
petroleum transportation industry. The hearing will be conducted in Dallas, Texas and commence within thirty (30) days after the selection of the third arbitrator. Seller, Buyer and the arbitrators shall proceed diligently and in good faith in
order that the award may be made as promptly as possible. Except as provided in the Federal Arbitration Act, the decision of the arbitrators will be binding on and non-appealable by the Parties hereto. The arbitrators shall have no right to grant or
award indirect, consequential, punitive or exemplary damages of any kind. The Arbitrable Disputes may be arbitrated in a common proceeding along with disputes under other agreements between Seller, Buyer or their Affiliates to the extent that the
issues raised in such disputes are related. Without the written consent of the Parties, no unrelated disputes or third party disputes may be joined to an arbitration pursuant to this Agreement. 

  
 14 

 10.6. Parties in Interest. This Agreement shall be binding upon and inure solely to the
benefit of each Party and their successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to confer upon any other person any rights or remedies of any nature whatsoever under or by reason of this Agreement.

 10.7. Assignment of Agreement. At any time, the Parties may make a collateral assignment of their rights under this Agreement to
any of their bona fide lenders or debt holders, or a trustee or a representative for any of them, and the non-assigning Parties shall execute an acknowledgment of such collateral assignment in such form as may from time to time be reasonably
requested; provided, however, that unless written notice is given to the non-assigning Parties that any such collateral assignment has been foreclosed upon, such non-assigning Parties shall be entitled to deal exclusively with Seller or HFC,
as the case may be, as to any matters arising under this Agreement, the Ancillary Documents or the Amended and Restated Omnibus Agreement (other than for delivery of notices required by any such collateral assignment). Except as otherwise provided
in this Section 10.7, neither this Agreement nor any of the rights, interests, or obligations hereunder may be assigned by any Party without the prior written consent of the other Parties. 

10.8. Captions. The captions in this Agreement are for purposes of reference only and shall not limit or otherwise affect the
interpretation hereof. 
 10.9. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same instrument. 
 10.10. Director and Officer Liability.
The directors, managers, officers, partners and stockholders of HFC, Buyer, Seller and their respective Affiliates shall not have any personal liability or obligation arising under this Agreement (including any claims that another party may assert)
other than, if applicable, as a direct party to or as an assignee of this Agreement or pursuant to a written guarantee. 
 10.11.
Integration. This Agreement, the Ancillary Documents and the Amended and Restated Omnibus Agreement supersede any previous understandings or agreements among the Parties, whether oral or written, with respect to their subject matter. This
Agreement, the Ancillary Documents and the Amended and Restated Omnibus Agreement contain the entire understanding of the Parties with respect to the subject matter hereof and thereof. No understanding, representation, promise or agreement, whether
oral or written, is intended to be or shall be included in or form part of this Agreement, the Ancillary Documents or the Amended and Restated Omnibus Agreement unless it is contained in a written amendment hereto or thereto and executed by the
Parties hereto or thereto after the date of this Agreement, the Ancillary Documents or the Amended and Restated Omnibus Agreement. To the extent that there is any conflict between the Ancillary Documents and this Agreement, this Agreement shall
prevail. 
 10.12. Effect of Agreement. The Parties ratify and confirm that except as otherwise expressly provided herein, in the
event this Agreement conflicts in any way with the Amended and Restated Omnibus Agreement, the terms and provisions of the Amended and Restated Omnibus Agreement shall control. 

  
 15 

 10.13. Amendment; Waiver. This Agreement may be amended only in a writing signed by all
parties hereto. Any waiver of rights hereunder must be set forth in writing. A waiver of any breach or failure to enforce any of the terms or conditions of this Agreement shall not in any way affect, limit or waive any party’s rights at any
time to enforce strict compliance thereafter with every term or condition of this Agreement. 
 10.14. Survival of Representations and
Warranties. The representations and warranties set forth in this Agreement shall survive the Closing until 5:00 p.m., Dallas, Texas time on, on the anniversary of the Closing Date, except that the representations and warranties contained in
Sections 4.1 (Organization), 4.2 (Authorization), 4.3(a) (Company Status), 4.6 (Title to LLC Interest; Capitalization), 4.9 (Taxes), 4.19 (Waivers and Disclaimers), 5.1 (Organization), 5.2
(Authorization), 6.1 (Organization) and 6.2 (Authorization) shall survive until the expiration of the applicable statute of limitations; provided, however, that any representation and warranty that is the subject of a claim for
indemnification hereunder which claim was timely made pursuant to Section 9.4(a) shall survive with respect to such claim until such claim is finally paid or adjudicated. 

ARTICLE XI 
 GUARANTEE

 11.1. Payment and Performance Guaranty. HFC unconditionally, absolutely, continually and irrevocably guarantees, as principal
and not as surety, to Buyer the punctual and complete payment in full when due of all Buyer Indemnified Costs by the Indemnifying Party under the Agreement (collectively, the “Payment Obligations”). HFC agrees that Buyer shall be
entitled to enforce directly against HFC any of the Payment Obligations. 
 11.2. Guaranty Absolute. HFC hereby guarantees that the
Payment Obligations will be paid strictly in accordance with the terms of the Agreement. The obligations of HFC under this Agreement constitute a present and continuing guaranty of payment, and not of collection or collectability. The liability of
HFC under this Agreement shall be absolute, unconditional, present, continuing and irrevocable irrespective of: 
 (a) any assignment or
other transfer of the Agreement or any of the rights thereunder of Buyer; 
 (b) any amendment, waiver, renewal, extension or release of or
any consent to or departure from or other action or inaction related to the Agreement; 
 (c) any acceptance by Buyer of partial payment or
performance from the Indemnifying Party; 
 (d) any bankruptcy, insolvency, reorganization, arrangement, composition, adjustment,
dissolution, liquidation or other like proceeding relating to the Indemnifying Party, or any action taken with respect to the Agreements by any trustee or receiver, or by any court, in any such proceeding; 

(e) any absence of any notice to, or Knowledge of, HFC, of the existence or occurrence of any of the matters or events set forth in the
foregoing subsections (a) through (d); or 
 (f) any other circumstance which might otherwise constitute a defense available to, or a
discharge of, a guarantor. 

  
 16 

 The obligations of HFC hereunder shall not be subject to any reduction, limitation, impairment or
termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or
unenforceability of the Payment Obligations or otherwise. 
 11.3. Waiver. HFC hereby waives promptness, diligence, all setoffs,
presentments, protests and notice of acceptance and any other notice relating to any of the Payment Obligations and any requirement for Buyer to protect, secure, perfect or insure any security interest or lien or any property subject thereto or
exhaust any right or take any action against the Indemnifying Party, any other entity or any collateral. 
 11.4. Subrogation Waiver.
HFC agrees that it shall not have any rights (direct or indirect) of subrogation, contribution, reimbursement, indemnification or other rights of payment or recovery from the Indemnifying Party for any payments made by HFC under this Article
XI until all Payment Obligations have been indefeasibly paid, and HFC hereby irrevocably waives and releases, absolutely and unconditionally, any such rights of subrogation, contribution, reimbursement, indemnification and other rights of
payment or recovery it may now have or hereafter acquire against the Indemnifying Party until all Payment Obligations have been indefeasibly paid. 

11.5. Reinstatement. The obligations of HFC under this Article XI shall continue to be effective or shall be reinstated, as the
case may be, if at any time any payment of any of the Payment Obligations is rescinded or must otherwise be returned to the Indemnifying Party or any other entity, upon the insolvency, bankruptcy, arrangement, adjustment, composition, liquidation or
reorganization of the Indemnifying Party or such other entity, or for any other reason, all as though such payment had not been made. 

11.6. Continuing Guaranty. This Article XI is a continuing guaranty and shall (i) remain in full force and effect until the
first to occur of the indefeasible payment in full of all of the Payment Obligations, (ii) be binding upon HFC, its successors and assigns and (iii) inure to the benefit of and be enforceable by Buyer and its successors, transferees and
assigns. 
 11.7. No Duty to Pursue Others. It shall not be necessary for Buyer (and HFC hereby waives any rights which HFC may have
to require Buyer), in order to enforce such payment by HFC, first to (i) institute suit or exhaust its remedies against the Indemnifying Party or others liable on the Payment Obligations or any other person, (ii) enforce Buyer’s
rights against any other guarantors of the Payment Obligations, (iii) join the Indemnifying Party or any others liable on the Payment Obligations in any action seeking to enforce this Article XI, (iv) exhaust any remedies available
to Buyer against any security which shall ever have been given to secure the Payment Obligations, or (v) resort to any other means of obtaining payment of the Payment Obligations.

B. In connection with each transaction between Relevant Asset Owner and the Related Refinery Owner, the Relevant Asset Owner leased from the
Related Refinery Owner real property at the Related Refinery Owner’s Refinery Complex on which all or a part of the Relevant Asset Owner’s Assets are located; 

C. Each Related Refinery Owner and the Relevant Asset Owner (except El Dorado Operating) has previously entered into a Prior Services
Agreement pursuant to which the applicable Related Refinery Owner provides certain Service Items to the Relevant Asset Owner that are necessary to operate and maintain such Relevant Asset Owner’s Assets at the Refinery Complex; 

D. Each Related Refinery Owner and each Relevant Asset Owner (except El Dorado Operating) entered into the Original Master Site Services
Agreement which amended and restated in its entirety their respective Prior Agreement from and after January 1, 2015, all in accordance with the terms and conditions set forth in the Original Master Site Services Agreement; and 

E. Each Related Refinery Owner and each Relevant Asset Owner now desires to amend and restate the Original Master Site Services Agreement in
its entirety, in accordance with the terms and conditions set forth herein. 
 NOW, THEREFORE, in consideration of the premises and the
covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows: 

ARTICLE 1 
 DEFINITIONS
AND INTERPRETATIONS 
 1.1 Definitions. Capitalized terms used throughout this Agreement and not otherwise defined herein shall
have the meanings set forth on Exhibit B. 
 1.2 Interpretation. Matters relating to the interpretation of this Agreement are set
forth on Exhibit C. 
 1.3 Independent Obligations. The Parties hereby acknowledge and agree that (a) the obligations of each

ARTICLE 2 
 RELATIONSHIP
OF PARTIES 
 2.1 Rights and Obligations. The Parties hereby enter into this Agreement for the purpose of setting forth their
respective rights and obligations relating to the provision by the Related Refinery Owner of the Service Items to the Relevant Asset Owner in connection with the Relevant Asset Owner’s ownership, operation and maintenance of its Relevant
Assets. 
 2.2 Nature of the Relationship. 

2.2.1 No Limitation on Separate Businesses. Except as provided herein, this Agreement shall not in any manner limit the Parties in
carrying on their respective separate businesses or operations or impose upon any Party a fiduciary duty vis-à-vis any other Party. 

2.2.2 Independent Operations. Each Related Refinery Owner and each applicable Relevant Asset Owner recognize that portions of each of
their respective businesses and operations are conducted within the Refinery Complex, and that necessary interactions result from such proximity. The respective businesses and operations of the Related Refinery Owner and Relevant Asset Owner will be
managed and conducted by them, as independent companies, and each shall act and conduct its business and operations independently wherever possible. Further, each Related Refinery Owner and Relevant Asset Owner recognize their mutual responsibility
to support the capability of each other to conduct their respective businesses and operations for routine and non-routine activities (including start-ups, shut downs, turnarounds, emergencies and other infrequent events). 

2.2.3 No Partnership. Notwithstanding the foregoing, nothing in this Agreement and no actions taken by the Related Refinery Owner and
the Relevant Asset Owner shall constitute a partnership, joint venture, association or other co-operative entity among the Related Refinery Owner and the Relevant Asset Owner or authorize either the Related Refinery Owner or the Relevant Asset Owner
to represent or contract on behalf of the other. Each Related Refinery Owner, as the supplier of the Service Items, is acting solely as an independent contractor and is not an agent of any Relevant Asset Owner. The provision of the Service Items
hereunder shall be under the sole supervision, control and direction of the Related Refinery Owner and not the Relevant Asset Owner. No Party is authorized to legally bind or act as an agent for any other Party. 

2.2.4 Permits. Notwithstanding the Relevant Asset Owner’s obligation to maintain and operate the Relevant Assets and Additional
Improvements and comply with Applicable Laws, the Related Refinery Owner and the Relevant Asset Owner acknowledge that the Related Refinery Owner may, as required by any applicable Governmental Authorities, maintain air quality and other
environmental permits in its name. Consequently and also for the ease of administration, the Related Refinery Owner may maintain in its name the air quality permits and other authorizations applicable to all, or part of, the Relevant Assets and
Additional Improvements and may be responsible for making any reports or other notifications to Governmental Authorities pursuant to such permits or Applicable Laws; provided that 

  
 2 

 
upon the Related Refinery Owner’s written request the Relevant Asset Owner shall apply for, obtain and maintain any such permits in its name. Nothing in this Agreement shall reduce the
Relevant Asset Owner’s obligations under Applicable Laws with respect to the Relevant Assets and Additional Improvements. 
 ARTICLE
3 
 PROVISION OF SERVICE ITEMS 

3.1 Provision of Service Items. 

3.1.1 Service Items. During the Applicable Term of this Agreement, the Related Refinery Owner shall make available and provide to the
Relevant Asset Owner, in accordance with the terms and conditions of this Agreement, the Service Items for such Relevant Asset Owner as described more fully on Exhibit D to this Agreement for use by the Relevant Asset Owner and any of its
Affiliates and agents in connection with the Relevant Asset Owner’s ownership, operation and maintenance of the Relevant Assets and any Additional Improvements. 

3.1.2 Quality of Service Items. If the Relevant Asset Owner reasonably believes in good faith that a Service Item
provided is not of the quality or quantity necessary to operate and maintain the Relevant Assets and any Additional Improvements as currently operated and maintained, the Relevant Asset Owner may deliver written notice of such claim to the Related
Refinery Owner. If the Related Refinery Owner does not reasonably satisfy the Relevant Asset Owner’s claim pursuant to the foregoing sentence within 30 days after receipt of such notice (or if such claim is of a nature that cannot be
resolved within 30 days, if the Related Refinery Owner does not commence to satisfy such claim within 30 days after receipt of such notice and thereafter diligently pursue satisfying such claim to completion), then the Relevant Asset Owner
may reject such Service Item and submit a proposal to the Related Refinery Owner to reduce the amount of the Annual Service Fee set forth on Exhibit E in accordance with Section 4.3. If the Related Refinery Owner refuses to
reduce the Annual Service Fee, the Dispute shall be resolved in accordance with the provisions of Article 9. 
 3.1.3
Notifications. The Related Refinery Owner shall notify the Relevant Asset Owner as soon as practicable of any actual or anticipated changes in the character of any Service Item or any actual or anticipated interruptions, shut-downs,
turnarounds or similar events that may adversely affect the provision of any Service Item. 
 3.1.4 Standard of Care. The Related
Refinery Owner shall provide all Service Items to the Relevant Asset Owner and perform all services hereunder in accordance with Standard Operating Practice. The provision of all Service Items and services hereunder shall be on a non-discriminatory
basis comparable to that provided or performed by the Related Refinery Owner with respect to its own business at the Refinery Complex unless otherwise specified herein. 

3.2 Increased Quantities and Additional Service Items. 

3.2.1 Adjustments to Service Items. If subsequent to the date hereof increased quantities of any Service Items are reasonably required
by a Relevant Asset Owner from the Related Refinery Owner in connection with its ownership, operation or maintenance of the Relevant Assets or any improvements or additions thereto, the Related Refinery Owner shall use commercially reasonable
efforts to provide such increased quantities of such Service Item on the same terms and conditions set forth in Exhibit D, so long as the provision of such increased quantities does not interfere in any material respect with the Related
Refinery Owner’s operations at the Refinery Complex or require the Related Refinery Owner to make a capital improvement to any Service Asset. If the provision by the Related Refinery 

  
 3 

 
Owner of increased quantities of any Service Item requested by the Relevant Asset Owner would require the Related Refinery Owner to make such a capital improvement, then the Relevant Asset Owner
may submit a request to the Related Refinery Owner pursuant to Section 6.1. The applicable Annual Service Fee with respect to increased quantities of any Service Item requested by a Relevant Asset Owner may be increased in accordance
with Article 4. Notwithstanding anything to the contrary herein, in the event that: 
 (a) the Relevant Asset Owner
uses the Relevant Assets to provide services to third parties, 
 (b) the Relevant Asset Owner’s provision of such
third-party services results in a material increase of any Service Item required by the Relevant Asset Owner, and 
 (c)
provision of such Service Items is available to the Relevant Asset Owner from third-party vendors on commercially reasonable terms, 
 then the Related
Refinery Owner may decline to provide such increased and additional Service Item. Further, if, in the Related Refinery Owner’s sole discretion, the provision of any Service Item by the Related Refinery Owner in connection with the Relevant
Asset Owner’s provision of services to third parties could expose the Related Refinery Owner or the Related Refinery Owner’s assets to environmental risk or liability, then the Related Refinery Owner may refuse to provide such Service Item
in connection with the Relevant Asset Owner’s provision of services to third parties. 
 3.2.2 New Service Items. If subsequent
to the date hereof one or more additional Service Items not specifically described herein, but which are being produced or utilized by the Related Refinery Owner or its Affiliates in the normal course of their operations at the Refinery Complex
(“Additional Service Items”), are or become reasonably necessary to operate or maintain the Relevant Assets and any Additional Improvements, the Related Refinery Owner shall use commercially reasonable efforts to provide such
Additional Service Items to the Relevant Asset Owner on terms and conditions consistent with the provision of the existing Service Items provided by the Related Refinery Owner. The applicable Annual Service Fee with respect to such Additional
Service Items may be increased in accordance with Article 4. 
 3.3 Use of Service Items. Each Relevant Asset Owner agrees to
utilize the Service Items provided to it by the Related Refinery Owner solely in connection with its ownership, operation and maintenance of the Relevant Assets and any Additional Improvements; provided, however, that no provision of this Agreement
shall obligate any Relevant Asset Owner in any way to utilize all or part of the Service Items provided by the Related Refinery Owner. 

3.4 Service Assets. Subject to Article 8, each Related Refinery Owner shall be responsible for operating and maintaining its respective
Service Assets, at its sole cost and expense, in accordance with Standard Operating Practice. Except for any capital improvement project proposed by a Relevant Asset Owner under Article 6 or undertaken by a Relevant Asset Owner under Article 5, the
Related Refinery Owner shall be responsible for all costs and expenses of any capital improvements to, or acquisitions of additional, Services Assets. 

3.5 Access. The relative rights of access for the Related Refinery Owner and the Relevant Asset Owner for each Refinery Complex are set
forth in the Master Lease and Access Agreement. 

  
 4 

 ARTICLE 4 

ANNUAL SERVICE FEE 
 4.1
Annual Service Fee. Within thirty (30) days following the end of each calendar month, the Relevant Asset Owner will pay the Related Refinery Owner an amount equal to one-twelfth (1/12) of the aggregate of its fees set forth on
Exhibit E (the “Annual Service Fee”) for the provision by the Related Refinery Owner and its Affiliates to the Relevant Asset Owner during such calendar month of all the Service Items described in Exhibit D. The monthly payment
for the first month under the Applicable Term of this Agreement will be prorated based on the number of days elapsed from the date of this Agreement through the last day of the first calendar month and the number of days in such calendar month. 

4.2 Increases in Annual Service Fee. 

4.2.1 Annual Adjustment. The Annual Service Fee shall be adjusted on July 1 of each calendar year, commencing on the first
July 1 following the Effective Date, by an amount equal to the PPI Adjustment; provided, that, effective as of the date hereof, the Annual Service Fee shall never be increased by more than 3% for any such calendar year. If the PPI is no longer
published, then the Parties shall negotiate in good faith to agree on a new index that gives comparable protection against inflation, and the same method of adjustment for increases in the new index shall be used to calculate increases in the Annual
Service Fee. If the Parties are unable to agree, a new index will be determined by binding arbitration in accordance with Section 9.1.4. 

4.2.2 Additional Cost Adjustment. Each Related Refinery Owner may also increase the Annual Service Fee to be paid by the Relevant Asset
Owner for any calendar year by an amount equal to the actual cost to the Related Refinery Owner of providing increased quantities of any Service Item or of providing any Additional Service Items pursuant to Section 3.2.1 and
Section 3.2.2 to the Relevant Asset Owner. 
 4.3 Reduction of Annual Service Fee. Within thirty (30) days following
the end of each calendar year, the Relevant Asset Owner will have the right to submit to the Related Refinery Owner a proposal to reduce the amount of the Annual Service Fee or other charges paid (or to be paid) for that year if the Relevant Asset
Owner reasonably believes, in good faith, that one or more Service Items provided by the Related Refinery Owner for that year was not of the quality or quantity necessary to operate and maintain the Relevant Assets as currently operated and
maintained. If the Relevant Asset Owner submits such a proposal to the Related Refinery Owner, the Relevant Asset Owner and the Related Refinery Owner shall determine in good faith the reduction, if any, to the Annual Service Fee for that year. If
the Parties are unable to reach an agreement with respect to any such proposals, such Dispute shall be resolved in accordance with Article 9. 

ARTICLE 5 
 CONNECTION
FACILITIES 
 5.1 Connection Facilities. 

5.1.1 Connection Facilities. Where necessary, the Relevant Asset Owner shall install or cause to be installed, at the expense of the
Relevant Asset Owner or, if mutually agreed, the Related Refinery Owner, one or more Connection Facilities, which shall be of a quality and type reasonably necessary to establish appropriate interconnections between the Relevant Assets and the
Service Assets. The design of any necessary Connection Facilities shall be submitted by the Relevant Asset Owner for review by the Related Refinery Owner. The Related Refinery Owner shall have thirty (30) days in which

  
 5 

 
to notify the Relevant Asset Owner of any modifications that are necessary to conform the design to Standard Operating Practices and to comply with requirements of Governmental Authorities,
otherwise the Related Refinery Owner shall be deemed to have approved such design. 
 5.1.2 Cooperation. The Relevant Asset Owner and
the Related Refinery Owner shall reasonably cooperate with one another with respect to the installation, operation and maintenance of the Connection Facilities so as to minimize any disruption to the operation of the Refinery Complex, the Relevant
Assets and the Service Assets. 
 ARTICLE 6 

CAPITAL IMPROVEMENTS 
 6.1
Capital Improvements Relating to Provision of Service Items. 
 6.1.1 Requests for Capital Improvements. The Relevant Asset Owner may
submit from time to time to the Related Refinery Owner written requests for the Related Refinery Owner to undertake capital improvement projects relating to the provision by the Related Refinery Owner of Service Items. Any such requests shall
specify in reasonable detail: 
 (a) the capital improvements to be made; 

(b) any permits that may be required; 

(c) the estimated cost of such capital improvements; 

(d) any proposed changes to this Agreement; and 

(e) any other relevant information relating to such capital improvement project. 

6.1.2 Response to Requests for Capital Improvements. The Related Refinery Owner agrees that it will consider in good faith any request
pursuant to Section 6.1.2, but it shall have no obligation to agree to undertake any such capital improvement project and may reject such request. The Related Refinery Owner shall provide the Relevant Asset Owner a written explanation for the
rejection of any request. If the Related Refinery Owner agrees to undertake any such capital improvement project, the Relevant Asset Owner shall be responsible for all costs associated with such project, without duplication of other amounts paid or
payable by the Relevant Asset Owner under this Agreement, including: 
 (a) the cost of completing the capital improvements;

 (b) the Related Refinery Owner’s costs and expenses incurred in connection with such project; and 

(c) any increased costs of operation incurred or to be incurred by the Related Refinery Owner as a result of such project; 

provided, however, that if other Persons receive any of the benefits of such capital improvement project, such other Persons shall bear their
respective pro rata shares of all costs associated with such project (based upon and only to the extent of the relative benefits received by them), and the Relevant Asset Owner’s costs with respect thereto shall be reimbursed by the Related
Refinery Owner as, when, if and to the extent savings are received or as, when, if and to the extent the other Person utilizes such benefits.

 ARTICLE 7 

MONITORING COMMITTEE 
 7.1
Monitoring Committee. 
 7.1.1 Monitoring Committee. Each Related Refinery Owner and Relevant Asset Owner shall jointly
establish a committee (the “Monitoring Committee”) to review the performance by the Related Refinery Owner and Relevant Asset Owner of this Agreement and the provision of Service Items by the Related Refinery Owner to the Relevant
Asset Owner hereunder in an effort to ensure the smooth and efficient performance of this Agreement. The Monitoring Committee shall be comprised of one representative from the Related Refinery Owner and one representative from the Relevant Asset

for processing.
