corporation, partnership, limited liability company, limited partnership, joint venture or other business association or entity, foreign or domestic.

of the transactions contemplated hereby and thereby will not, (i) violate, conflict with, or result in any breach of any provision of Seller’s organizational documents or (ii) subject to obtaining the Consents or making the
registrations, declarations or filings set forth in the next sentence, violate in any material respect any Applicable Law or material Contract binding upon such Seller. Except as set forth on Schedule 4.4(a), no Consent of any Governmental

4.6. Title to LLC Interest; Capitalization. 

(a) Seller is the record owner of and has good and valid title to the LLC Interest, free and clear of all Encumbrances, and sole and
unrestricted voting power and power of disposition with respect to all of the LLC Interest. Except for any Claims arising under this Agreement and any other agreement entered into by Seller in connection with this Agreement, Seller and its
Affiliates have no Claims of any kind against the Company, or any of its officers, managers, directors or employees. The LLC Interest has been duly authorized and validly issued in accordance with Applicable Laws and the organizational documents of
the Company, including its limited liability company agreement, and is fully paid (to the extent required by the limited liability company agreement of the Company) and nonassessable (except to the extent such nonassessability may be affected by

LLC Interest, (ii) there are no outstanding options, warrants, subscriptions, puts, calls or other rights, agreements, arrangements or commitments (preemptive, contingent or otherwise) obligating Seller or Company to offer, issue, sell, redeem,
repurchase, otherwise acquire or transfer, pledge or encumber any securities of or equity interest in the Company; and (iii) there are no outstanding securities or obligations of any kind of any of the Company that are convertible into or
exercisable or exchangeable for any equity interest in the Company. 

  
 5 








 (c) Upon payment of the Purchase Price, Buyer will have the entire record and beneficial
ownership of the LLC Interest, free and clear of all Encumbrances. 
 4.7. No Undisclosed Liabilities. Except as set forth on
Schedules 4.7 and 4.13, the Company does not now have any indebtedness or liability (whether absolute, accrued, contingent or otherwise) of any nature, other than its obligations under the Material Contracts and Permits, and
(a) neither Seller (or any other HFC Entity, as the case may be) nor to Seller’s Knowledge, any counterparty thereto, was in material breach of its obligations under the Material Contracts at the time of the Asset Contribution and
(b) neither the Company, nor to Seller’s Knowledge, any counterparty thereto, is currently in material breach of its obligations under the Material Contracts. 

4.8. No Employees. The Company does not now have nor has it ever had any employees. 

4.9. Taxes. The Company has filed, on or before the applicable due date (including any extensions thereof), all material tax returns
that it was required to file, and all such tax returns were accurate, correct, and complete in all material respects. All taxes due and owing by the Company have been paid in full or are being properly contested. The Company is, and at all time
since its formation has been, disregarded as an entity separate from Seller for U.S. federal income tax purposes, and no election has been filed on or before the Closing Date that would change such classification on or after the Closing Date. 

4.10. Brokers and Finders. No investment banker, broker, finder, financial advisor or other intermediary has been retained by or is
authorized to act on behalf of Seller who is entitled to receive from Buyer any fee or commission in connection with the transactions contemplated by this Agreement. 

4.11. Condition of Assets. To Seller’s Knowledge, the Assets are in good operating condition and repair (normal wear and tear
excepted), are free from material defects (patent and latent), are suitable for the purposes for which they are currently used and are not in need of material maintenance or repairs except for ordinary routine maintenance and repairs. 

4.12. Title to Assets. The Company owns, leases or has the legal right to use all the properties and assets used by the Company in the
operation of its business, in each case subject to no Encumbrances, except Permitted Encumbrances. All of the Company’s assets consist of the Assets. Except as disclosed in Schedule 4.7, the Company owns the Assets free and clear of all
Encumbrances other than Permitted Encumbrances. 
 4.13. Permits. Except as set forth in Schedule 4.13, the Company owns or
holds all franchises, licenses, permits, consents, approvals and authorizations of any Governmental Authority necessary for the ownership and operation of the Assets (collectively, the “Permits”). Each Permit is in full force and
effect, and the Company is in compliance with all of its obligations with respect thereto. To the Knowledge of Seller, no event has occurred that causes, or upon the giving of notice or the lapse of time or otherwise would cause, revocation or
termination of any Permit. All Permits shall be, subject to Permitted Encumbrances, owned or held by the Company at Closing. 

  
 6 








 4.14. Banking Relationships. Schedule 4.14 sets forth a complete and accurate list
of all accounts, including checking accounts, cash contribution accounts, safe deposit boxes, borrowing arrangements and certificates of deposit that the Company has with any banks, savings and loan associations or other financial institutions,
indicating in each case account numbers, if applicable, and the person or persons authorized to act or sign on behalf of the Company in respect of the foregoing. No person holds any power of attorney or similar authority from the Company with
respect to such accounts. 
 4.15. Material Contracts. Except as set forth on Schedule 4.15, and other than the Construction
Contracts, there are no material Contracts relating to the activities currently conducted by the Company with respect to the Assets, or by which the Company or the Assets are bound. 

4.16. Seller Security. Schedule 4.16 contains a true and complete listing of the cash collateral, letters of credit, and
guaranties in effect as of the date of this Agreement securing the performance of the Company under the Material Contracts and other obligations of the Company with respect to the activities currently conducted by the Company with respect to the
Assets. 
 4.17. Insurance. All insurance policies covering the Company or its operations and Assets provided by Seller (which, for
the avoidance of doubt, excludes insurance policies covering the Company or its operations and Assets provided by the Partnership and its Affiliates) are in full force and effect, all premiums with respect thereto covering all periods up to and
including the Closing Date have been paid, and no written notice of cancellation or termination has been received with respect to any such policy. Such policies, including without limitation products liability insurance, (a) are sufficient for
compliance in all material respects with all requirements of Applicable Law and of all Material Contracts for matters covered by such policies, and (b) are, to the Knowledge of Seller, valid policies, enforceable against the Company and the
other parties thereto, in accordance with their respective terms, except to the extent that such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar
Applicable Laws affecting creditors’ rights and remedies generally and (ii) equitable principles which may limit the availability of certain equitable remedies (such as specific performance) in certain instances. 

4.18. Information Provided by Seller. 

(a) Seller and its Affiliates have not knowingly withheld disclosure from the Buyer of any fact that would, individually or in the aggregate,
have a Material Adverse Effect on the Partnership, the Buyer, the Company or the Assets. 
 (b) The information for the Assets provided to

 ARTICLE IX

9.2. Defense of Third-Party Claims. An Indemnified Party shall give prompt written notice to Seller or Buyer, as applicable (the
“Indemnifying Party”), of the commencement or assertion of any action, proceeding, demand, or claim by a third party (collectively, a “third- party action”) in
respect of 

  
 10 








 
which such Indemnified Party seeks indemnification hereunder. Any failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it, he, or she may
have to such Indemnified Party under this Article IX unless the failure to give such notice materially and adversely prejudices the Indemnifying Party. The Indemnifying Party shall have the right to assume control of the defense of, settle,
or otherwise dispose of such third-party action on such terms as it deems appropriate; provided, however, that: 
 (a) The
Indemnified Party shall be entitled, at its own expense, to participate in the defense of such third-party action (provided, however, that the Indemnifying Party shall pay the attorneys’ fees of the Indemnified Party if
(i) the employment of separate counsel shall have been authorized in writing by the Indemnifying Party in connection with the defense of such third-party action, (ii) the Indemnifying Party shall not have employed counsel reasonably
satisfactory to the Indemnified Party to have charge of such third-party action, (iii) the Indemnified Party shall have reasonably concluded that there may be defenses available to such Indemnified Party that are different from or additional to
those available to the Indemnifying Party, or (iv) the Indemnified Party’s counsel shall have advised the Indemnified Party in writing, with a copy delivered to the Indemnifying Party, that there is a material conflict of interest that
could violate applicable standards of professional conduct to have common counsel); 
 (b) The Indemnifying Party shall obtain the prior
written approval of the Indemnified Party before entering into or making any settlement, compromise, admission, or acknowledgment of the validity of such third-party action or any liability in respect thereof if, pursuant to or as a result of such
settlement, compromise, admission, or acknowledgment, injunctive or other equitable relief would be imposed against the Indemnified Party or if, in the opinion of the Indemnified Party, such settlement, compromise, admission, or acknowledgment could
have a Material Adverse Effect on its business; 
 (c) The Indemnifying Party shall not consent to the entry of any judgment or enter into
any settlement that does not include as an unconditional term thereof the giving by each claimant or plaintiff to each Indemnified Party of a release from all liability in respect of such third-party action; and 

(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
prior written consent of such Indemnifying Party. 
 The Parties shall extend reasonable cooperation in connection with the defense of any third-party
action pursuant to this Article IX and, in connection therewith, shall furnish such records, information, and testimony and attend such conferences, discovery proceedings, hearings, trials, and appeals as may be reasonably requested. 

9.3. Direct Claims. In any case in which an Indemnified Party seeks indemnification hereunder which is not subject to
Section 9.2 because no third-party action is involved, the Indemnified Party shall notify the Indemnifying Party in writing of any Indemnified Costs which such Indemnified Party claims are subject to indemnification under the terms
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. 

  
 11 








 9.4. Limitations. The following provisions of this Section 9.4 shall limit the
indemnification obligations hereunder: 
 (a) Limitation as to Time. The Indemnifying Party shall not be liable for any Indemnified
Costs pursuant to this Article IX unless a written claim for indemnification in accordance with Section 9.2 or Section 9.3 is given by the Indemnified Party to the Indemnifying Party with respect thereto on or before
5:00 p.m., Dallas, Texas time, on the anniversary of the Closing Date; provided that the Indemnifying Party shall be liable for Indemnified Costs with respect to claims for indemnification for breach of 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), if a written claim for indemnification in accordance with Section 9.2 or Section 9.3 is given by the Indemnified Party to the Indemnifying Party at
any time prior to the expiration of the applicable statute of limitations. 
 (b) Sole and Exclusive Remedy. Each Party acknowledges
and agrees that, after the Closing Date, notwithstanding any other provision of this Agreement to the contrary, Buyer’s and the other Buyer Indemnified Parties’ and Seller and the other Seller Indemnified Parties’ sole and exclusive
remedy with respect to the Indemnified Costs shall be in accordance with, and limited by, the provisions set forth in this Article IX. The Parties further acknowledge and agree that the foregoing is not the remedy for and does not limit the
Parties’ remedies for matters covered by the indemnification provisions contained in the Omnibus Agreement. 
 9.5. Tax Related
Adjustments. Seller and Buyer agree that any payment of Indemnified Costs made hereunder will be treated by the Parties on their tax returns as an adjustment to the Purchase Price.

 (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.

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.

 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.
