          (a) In consideration of the rents, covenants, and agreements set forth herein and subject to the terms and conditions hereof, Lessor hereby leases to Lessee and Lessee hereby leases from Lessor, the Premises for a term commencing on the effective date hereof (the “Commencement Date”) and ending at midnight on the date which is fifty (50) years after the date hereof, and after such date the term of this Lease shall be automatically renewed for a maximum of four (4) successive ten-year periods thereafter (the “Term”); provided, however, Lessee may terminate this Lease at the end of such initial period or any subsequent ten-year period by delivering written notice to Lessor, on or before 180 days prior to the end of any such period, that Lessee has elected to terminate this Lease.

          (b) At Lessee’s option, Lessee may terminate this Lease, by providing written notice to Lessor on or before 180 days prior to the desired termination date if Lessee ceases to operate the Relevant Assets and Additional Improvements or ceases its business operations. In the event of such termination pursuant to this Section 2.1(b), Lessor shall retain one half of the remaining Rent (as defined below) for the then current 12-month rental period as set forth in Section 2.3 below as its sole and exclusive remedy for such early termination and shall refund to Lessee the remaining Rent.

     2.2 Access.

          (a) Lessor hereby grants to Lessee and its respective Affiliates, agents, employees and contractors (collectively, “Lessee’s Parties”) free of charge, an irrevocable, non-exclusive right of access to and use of those portions of the Refinery Site that are reasonably necessary for access to and/or the operation of the Relevant Assets and Additional Improvements by Lessee as a stand-alone enterprise, all so long as such access and use by any of Lessee’s Parties does not unreasonably interfere in any material respect with Lessor’s operations at the Refinery Site and complies with Lessor’s rules, norms and procedures governing safety and security at the Refinery Site. The facilities on the Refinery Site that are subject to the access and use rights provided under this Section, are referred to herein as the “Shared Access Facilities”.

Notwithstanding the foregoing, the provisions of this Section 2.2(a) shall relate only to access and use of the Shared Access Facilities, and the Site Services Agreement shall cover all services that are to be provided by Lessor under the terms of the Site Services Agreement.

          (b) Lessor hereby retains for itself and its Affiliates, agents, employees and contractors (collectively, “Lessor’s Parties”), the right of access to all of the Premises and the Relevant Assets (i) to determine whether the conditions and covenants contained in this Lease are being kept and performed, (ii) to comply with Environmental Laws, and (iii) to inspect, maintain, repair, improve and operate the SUMF Assets and the Shared Access Facilities and any assets of Lessor located on the Premises or to install or construct any structures or equipment necessary for the maintenance, operation or improvement of any such assets or the installation, construction or maintenance of any Connection Facilities, all so long as such access by Lessor’s Parties does not unreasonably interfere in any material respect with Lessee’s operations on the Premises and complies with Lessee’s rules, norms and procedures governing safety and security at the Premises.

     2.3 Rent. As rental for the Premises during the Term, Lessee agrees to pay to Lessor for each 12-month period of the Term One Hundred and 00/100 ($100.00) (the “Rent”) on or before the 1st day of each 12-month period, the first such payment being due within 30 days of the Commencement Date of the Term.

     2.4 Place of Payment. All Rent shall be payable in lawful money of the United States of America at Lessor’s address set forth in Section 11.7.

     2.5 Net Lease. Except as herein otherwise expressly provided in this Lease and in the Ancillary Agreements, this is a net lease and Lessor shall not at any time be required to pay any utility charges or any costs associated with the maintenance, repair, alteration or improvement of the Premises or to provide any services or do any act or thing with respect to the Premises or any part thereof or any appurtenances thereto, and the Rent reserved herein shall be paid without any claim on the part of Lessee for diminution, setoff or abatement and nothing shall suspend, abate or reduce any Rent to be paid hereunder, except as expressly provided herein.

ARTICLE III
CONDUCT OF BUSINESS

     3.1 Use of Premises. Lessee shall have the right to use the Premises for the purpose of owning, operating, maintaining, repairing, replacing, improving, and expanding the Relevant Assets and the Additional Improvements and for any other lawful purpose associated with the operation and ownership of the Relevant Assets and the Additional Improvements.

     3.2 Waste. Subject to the obligations of Lessor under the Ancillary Agreements, Lessee shall not commit, or suffer to be committed, any waste to the Premises, ordinary wear and tear or casualty excepted.

     3.3 Governmental Regulations. Subject to the obligations of Lessor to Lessee under this Lease and the Ancillary Agreements including the indemnity provisions contained in the Ancillary Agreements, Lessee shall, at Lessee’s sole cost and expense, at all times comply with

all applicable requirements (including requirements under Environmental Laws) of all Governmental Authorities now in force, or which may hereafter be in force, pertaining to the Premises, and shall faithfully observe all Laws now in force or which may hereafter be in force pertaining to the Premises or the use, maintenance or operation thereof. Lessee shall give prompt written notice to Lessor of Lessee’s receipt from time to time of any notice of non-compliance, order or other directive from any court or other Governmental Authority under Environmental Laws relating to the Premises. If Lessor reasonably believes at any time that Lessee is not complying with all applicable legal requirements (including requirements under Environmental Laws) with respect to the Relevant Assets and Additional Improvements, it will provide reasonable notice to Lessee of such condition. If Lessee fails to take appropriate action to cause such assets to comply with applicable Laws or take other actions required under applicable Laws within 30 days of Lessor’s reasonable notice, Lessor may, without further notice to Lessee, take such actions for Lessee’s account. Within 30 days following the date Lessor delivers to Lessee evidence of payment for those actions by Lessor reasonably necessary to cause the Relevant Assets and Additional Improvements to achieve compliance with applicable Laws because of Lessee’s failure to do so, Lessee shall reimburse Lessor all amounts paid by Lessor on Lessee’s behalf.

     3.4 Air Quality Permits. Notwithstanding Lessee’s obligation to maintain and operate the Relevant Assets and Additional Improvements and comply with applicable Laws, Lessor and Lessee acknowledge that Lessor may, as required by any applicable Governmental Authorities, maintain air quality permits in its name. Consequently and also for the ease of administration, Lessor 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 Laws; provided that upon Lessor’s written request Lessee shall apply for, obtain and maintain any such permits in its name. Except as provided in the preceding sentence, nothing in this Lease shall reduce Lessee’s obligations under Laws with respect to the Relevant Assets and Additional Improvements.

     3.5 Utilities. Lessor shall provide all utilities (electricity, natural gas, water, steam, etc.) necessary for Lessee’s operation of the Relevant Assets and the Additional Improvements in accordance with the provisions of the Site Services Agreement.

ARTICLE IV
ALTERATIONS, ADDITIONS AND IMPROVEMENTS

     Subject to the provisions of this Article IV, Lessee may make any alterations, additions, improvements or other changes to the Premises and the Relevant Assets as may be necessary or useful in connection with the operation of the Relevant Assets (collectively, the “Additional Improvements”). If such Additional Improvements require alterations, additions or improvements to the Premises or any of the Shared Access Facilities, Lessee shall notify Lessor in writing in advance and the parties shall negotiate in good faith any increase to the fees paid by Lessee under the Site Services Agreement by Lessee or otherwise provide for reimbursement of any material increase in cost (if any) to Lessor under the Site Services Agreement that results from any modifications to the Premises or the Shared Access Facilities necessary to accommodate the Additional Improvements, or as otherwise mutually agreed by the parties. Any

alteration, addition, improvement or other change to the Premises, Relevant Assets or Additional Improvements (and, if agreed by Lessee and Lessor, to the Shared Access Facilities) by Lessee shall be made in a good and workmanlike manner and in accordance with all applicable Laws. The Relevant Assets and all Additional Improvements shall remain the property of Lessee and shall be removed by Lessee within one (1) year after termination of this Lease (provided that such can be removed by Lessee without unreasonable damage or harm to the Premises) or, at Lessee’s option exercisable by notice to Lessor, surrendered to Lessor upon the termination of this Lease. Lessee shall not have the right or power to create or permit any lien of any kind or character on the Premises by reason of repair or construction or other work. In the event any such lien is filed against the Premises, Lessee shall cause such lien to be discharged or bonded within thirty (30) days of the date of filing thereof.

ARTICLE V
MAINTENANCE OF PREMISES

     5.1 Maintenance by Lessee. Except as otherwise expressly provided in this Article V and in Article VII or elsewhere in this Lease and subject to the obligations of Lessor and Lessee under the Ancillary Agreements, including any indemnity provisions contained in the Ancillary Agreements, Lessee shall at its sole cost, risk and expense at all times keep the Premises and Additional Improvements (to the extent such Additional Improvements are located on the Shared Access Facilities) in good order and repair and make all necessary repairs thereto, structural and nonstructural, ordinary and extraordinary, and unforeseen and foreseen. When used in this Section 5.1, the term “repairs” shall include all necessary replacements, renewal, alterations and additions. All repairs made by Lessee shall be made in accordance with normal and customary practices in the industry, in a good and workmanlike manner, and in accordance with all applicable Laws.

     5.2 Operation of Premises. Subject to the obligations of Lessor and Lessee in this Lease and under the Ancillary Agreements, including any indemnity provisions contained in the Ancillary Agreements, Lessee covenants and agrees to operate the Relevant Assets and Additional Improvements located on the Premises in accordance with normal and customary practices in the industry and all applicable Laws and other requirements of applicable Governmental Authorities now in force, or which may hereafter be in force, pertaining to the Premises or the use or operation thereof.

     5.3 Surrender of Premises. Lessee shall at the expiration of the Term or at any earlier termination of this Lease, surrender the Premises to Lessor in as good condition as it received the same, ordinary wear and tear, and limitations permitted by Article VII excepted and in accordance with the provisions of Article IV.

     5.4 Release of Hazardous Substances. Lessee shall give prompt notice to Lessor of any release of any Hazardous Substances on or at the Premises not in compliance with Environmental Laws that occur during the Term. Lessor shall immediately take all steps necessary to contain or remediate (or both) any such release and provide any governmental notifications required by Law. If Lessor believes at any time that Lessee is failing to contain or remediate in compliance with all applicable Laws (including Environmental Laws) any release arising from Lessee’s operation of the Relevant Assets or Additional Improvements or Lessee’s

failure to comply with its obligations pursuant to this Lease, Lessor will provide reasonable notice to Lessee of such failure. If Lessee fails to take appropriate action to contain or remediate such a release or take other actions required under applicable Laws or this Lease within 30 days of Lessor’s reasonable notice, Lessor may, without further notice to Lessee, take such actions for Lessee’s account. Within 30 days following the date Lessor delivers to Lessee evidence of payment for those actions by Lessor reasonably necessary to contain or remediate a release or otherwise achieve compliance with applicable Laws or this Lease because of Lessee’s failure to do so, Lessee shall reimburse Lessor all amounts paid by Lessor on Lessee’s behalf.

ARTICLE VI
TAXES, ASSESSMENTS

     6.1 Lessee’s Obligation to Pay. Lessee shall pay during the Term, all federal, state and local real and personal property ad valorem taxes, assessments, and other governmental charges, general and special, ordinary and extraordinary, including assessments for public improvements or benefits assessed against the Premises, or improvements situated thereon, including the Relevant Assets and all Additional Improvements (but excluding any Shared Access Facilities and any SUMF Assets) for the period after the Commencement Date, that are payable to any lawful authority assessed against or with respect to the Premises or the use or operation thereof during the Term, including any federal, state or local income, gross receipts, withholding, franchise, excise, sales, use, value added, recording, transfer or stamp tax, levy, duty, charge or withholding of any kind imposed or assessed by any federal, state or local government, agency or authority, together with any addition to tax, penalty, fine or interest thereon, other than state or U.S. federal income tax imposed upon the taxable income of Lessor and any franchise taxes imposed upon Lessor (such taxes and assessments being hereinafter called “Taxes”). In the event that Lessee fails to pay its share of such Taxes in accordance with the provisions of this Section 6.1 prior to the time the same become delinquent, Lessor may pay the same and Lessee shall reimburse Lessor all amounts paid by Lessor on Lessee’s behalf within 30 days following the date Lessor delivers to Lessee evidence of such payment.

     6.2 Manner of Payment. Upon notice by Lessee to Lessor, Lessor and Lessee shall use commercially reasonable efforts to cause the Premises and the Relevant Assets (including all Additional Improvements but excluding Shared Access Facilities and any SUMF Assets) to be separately assessed for purposes of Taxes as soon as reasonably practicable following the Commencement Date (to the extent allowed by applicable Law). During the Term but subject to the provisions of Section 6.1, Lessee shall pay all Taxes assessed directly against the Premises, the Relevant Assets and the Additional Improvements (but excluding the Shared Access Facilities and any SUMF Assets) directly to the applicable taxing authority prior to delinquency and shall promptly thereafter provide Lessor with evidence of such payment. Until such time as Lessor and Lessee can cause the Premises, the Relevant Assets and the Additional Improvements (but excluding the Shared Access Facilities and any SUMF Assets) to be separately assessed as provided above, Lessee shall reimburse Lessor, upon request, for any such Taxes paid by Lessor to the applicable taxing authorities (such reimbursement to be based upon the mutual agreement of the Lessor and Lessee as to the portion of such Taxes attributable to the Premises, the Relevant Assets and the Additional Improvements), subject to the terms of Section 6.1. The certificate issued or given by the appropriate officials authorized or designated by law to issue or give the same or to receive payment of such Taxes shall be prima facie evidence of the existence,

payment, nonpayment and amount of such Taxes. Lessee may contest the validity or amount of any such Taxes or the valuation of the Premises and/or the Relevant Assets and the Additional Improvements (to the extent any of the foregoing may be separately issued), at Lessee’s sole cost and expense, by appropriate proceedings, diligently conducted in good faith in accordance with applicable Law. If Lessee contests such items then Lessor shall cooperate with Lessee in any such contesting of the validity or amount of any such Taxes or the valuation of the Premises and/or the Relevant Assets and the Additional Improvements. Taxes for the first and last years of the Term shall be prorated between the Parties based on the portions of such years that are coincident with the applicable tax years and for which each applicable Party is responsible.

ARTICLE VII
EMINENT DOMAIN; CASUALTY; INSURANCE

     7.1 Total Condemnation of Premises. If the whole of the Premises are acquired or condemned by eminent domain for any public or quasi-public use or purpose, then this Lease shall terminate as of the date title vests in any public agency. All rentals and other charges owing hereunder shall be prorated as of such date.

     7.2 Partial Condemnation. If any part of the Premises is acquired or condemned as set forth in Section 7.1, and if in Lessee’s reasonable opinion such partial taking or condemnation renders the Premises unsuitable for the business of Lessee, then this Lease shall terminate at Lessee’s election as of the date title vests in any public agency, provided Lessee delivers to Lessor written notice of such election to terminate within 60 days following the date title vests in such public agency. In the event of such termination, all rentals and other charges owing hereunder shall be prorated as of such effective date of termination.

     7.3 Damages and Right to Additional Property. Lessor shall be entitled to any award and all damages payable as a result of any condemnation or taking of the fee title of the Premises, provided that the net amount which may be awarded or tendered to Lessor in such condemnation proceedings (less all legal and other expenses incurred by Lessor in connection with such taking) shall (as long as Lessee is not then in default hereunder) be used to pay for any restoration by Lessee of the Relevant Assets, the Additional Improvements and/or the remainder of the Premises hereof to the extent Lessee desires any of the same to be restored. Lessee shall have the right to claim and recover from the condemning authority, but not from Lessor, such compensation as may be separately awarded or recoverable by Lessee in Lessee’s own right on account of any and all damage to the Relevant Assets, the Additional Improvements and/or Lessee’s business by reason of the condemnation, including loss of value of any unexpired portion of the Term, and for or on account of any cost or loss to which Lessee might be put in removing Lessee’s personal property, fixtures, leasehold improvements and equipment, including the Relevant Assets and the Additional Improvements, from the Premises.

          During any periods of time during which the Relevant Assets and/or Additional Improvements are destroyed, damaged, or are being restored or reconstructed (each a “Casualty Event”) under the terms of this Section, Rent hereunder shall be abated in the proportion that Lessee’s use thereof is impacted by such Casualty Event, on the condition that Lessee uses commercially reasonable efforts to mitigate the disruption to its business caused by such Casualty Event.

     7.4 Insurance. Except as otherwise agreed by Lessor and Lessee, Lessee shall, at all times, maintain or cause to be maintained insurance with respect to the Premises, the Relevant Assets and the Additional Improvements in accordance with the requirements identified on Schedule 7.4 hereto.

ARTICLE VIII
ASSIGNMENT AND SUBLETTING

     8.1 Assignment and Subletting. This Agreement may be assigned in connection with, and subject to the terms and conditions set forth in Section 13(b) of, the Throughput Agreement, which such terms and conditions are incorporated herein by reference.

     8.2 Release of Lessor. Any assignment of this Lease by Lessor in accordance with Section 8.1 shall operate to terminate the liability of Lessor for all obligations under this Lease accruing after the date of any such assignment.

     8.3 Release of Lessee. Any assignment of this Lease by Lessee in accordance with Section 8.1 shall operate to terminate the liability of Lessee for all obligations under this Lease accruing after the date of any such assignment.

DEFAULTS; REMEDIES; TERMINATION

     9.1 Default by Lessee. The occurrence of any one or more of the following events shall constitute a material default and breach of this Lease by Lessee:

          (a) The failure by Lessee to make when due any payment of Rent or any other payment required to be made by Lessee hereunder, if such failure continues for a period of 90 days following written notice from Lessor;

          (b) The failure by Lessee to observe or perform any of the other covenants, conditions or provisions of this Lease to be observed or performed by Lessee, if such failure continues for a period of 90 days following written notice from Lessor; provided, however, if a reasonable time to cure such default would exceed 90 days, Lessee shall not be in default so long as Lessee begins to cure such default within 90 days of receiving written notice from Lessor and thereafter completes the curing of such default within reasonable period of time (under the circumstances) following the receipt of such written notice from Lessor; or

          (c) The occurrence of any Bankruptcy Event.

     9.2 Lessor’s Remedies.

          (a) In the event of any such material default under or material breach of the terms of this Lease by Lessee, Lessor may, at Lessor’s option, at any time thereafter that such default or breach remains uncured, without further notice or demand, terminate this Lease and Lessee’s right to possession of the Premises and forthwith repossess the Premises by any lawful means in which event Lessee shall immediately surrender possession of the Premises to Lessor; and any such action on the part of Lessor shall be in addition to any other remedy that may be

available to Lessor for arrears of Rent or breach of contract, or otherwise, including the right of setoff.

          (b) If, by the terms of this Lease, Lessee is required to do or perform any act or to pay any sum to a Third Party, and fails or refuses to do so, Lessor, after 30 days written notice to Lessee, without waiving any other right or remedy hereunder for such default, may do or perform such act, at Lessee’s expense, or pay such sum for and on behalf of Lessee, and the amounts so expended by Lessor shall be repayable on demand, and bear interest from the date expended by Lessor until paid at a rate equal to the lesser of (i) an interest rate equal to the “Prime Rate” as published in The Wall Street Journal, Southwest Edition, in its listing of “Money Rates” plus two percent (2%) or (ii) the maximum non-usurious rate of interest permitted to be charged Lessee under applicable Law (the “Post-Maturity Rate”). Past due Rent and any other past due payments required hereunder shall bear interest from maturity until paid at the Post-Maturity Rate.

     9.3 Default by Lessor. The occurrence of any one or more of the following events shall constitute a material default and breach of this Lease by Lessor:

          (b) The occurrence of a Bankruptcy Event.

     9.4 Lessee’s Remedies. In the event of any such default under or breach of the terms of this Lease by Lessor, Lessee may, at Lessee’s option, at any time thereafter that such default or breach remains uncured, after ten days prior written notice to Lessee, perform any act that Lessor is required to do or perform any act or to pay any sum to a Third Party, at Lessor’s expense (to the extent the terms of this Lease require such performance at Lessor’s expense) or pay such sum for and on behalf of Lessor, and the amounts so expended by Lessee shall be repayable on demand, and bear interest from the date expended by Lessee until paid at the Post-Maturity Rate. Lessee may, at Lessee’s option, deduct any such amounts so expended by Lessee from the Rent and any other amounts owed hereunder or under any Ancillary Agreement and any such action on the part of Lessee shall be in addition to any other remedy that may be available to Lessee for default or breach of contract, or otherwise, including the right of setoff.

obligations, losses, damages, penalties, demands, claims (including claims involving strict or absolute liability in tort), actions, suits, costs, expenses and disbursements (including reasonable legal fees and expenses) of any kind and nature whatsoever (collectively, the “Claims”) which may be imposed on, incurred by or asserted against any of the Lessee Indemnified Parties, in any way relating to or arising out of (a) any failure to perform any covenant or agreement made or undertaken by Lessor in this Lease, or (b) the exercise of Lessor’s rights and obligations under Section 2.2(b); provided, however, Lessor shall not have any obligation to indemnify the Lessee Indemnified Parties for any such Claim under clauses (a) or (b) to the extent resulting from or arising out of the willful misconduct or negligence (standard negligence or gross negligence) of any of the Lessee Indemnified Parties. To the extent that the Lessee Indemnified Parties in fact receive full indemnification payments from Lessor under the indemnification provisions of this Section 10.1, Lessor shall be subrogated to the Lessee Indemnified Parties’ rights with respect to the transaction or event requiring or giving rise to such indemnity. NOTWITHSTANDING ANYTHING CONTAINED IN THIS LEASE TO THE CONTRARY, IN NO EVENT SHALL LESSOR BE LIABLE FOR INCIDENTAL, INDIRECT, SPECIAL, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES IN TORT, CONTRACT OR OTHERWISE UNDER OR ON ACCOUNT OF THIS LEASE, EXCEPT THOSE PAYABLE TO THIRD PARTIES FOR WHICH LESSOR WOULD BE LIABLE UNDER THIS SECTION.

To the extent that the Lessor Indemnified Parties in fact receive full indemnification payments from Lessee under the indemnification provisions of this Section 10.2, Lessee shall be subrogated to the Lessor Indemnified Parties’ rights with respect to the transaction or event requiring or giving rise to such indemnity. NOTWITHSTANDING ANYTHING CONTAINED IN THIS LEASE TO THE CONTRARY, IN NO EVENT SHALL LESSEE BE LIABLE FOR INCIDENTAL, INDIRECT, SPECIAL, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES IN TORT, CONTRACT OR OTHERWISE UNDER OR ON ACCOUNT OF THIS LEASE, EXCEPT THOSE PAYABLE TO THIRD PARTIES FOR WHICH LESSEE WOULD BE LIABLE UNDER THIS SECTION.

     10.3 Matters Involving a Third Party. If any Third Party shall notify either Lessor or Lessee with respect to any action or claim by a Third Party (a “Third-Party Claim”) that may give rise to a right to claim for indemnification against the other Party under Section 10.1 or

Section 10.2, then the Indemnified Party shall promptly notify the Indemnifying Party thereof in writing; provided, however, that failure to give timely notice shall not affect the right to indemnification to the extent such failure to give timely notice is not prejudicial to the Indemnifying Party.

     10.5 Ancillary Agreements. The Ancillary Agreements contain additional indemnity provisions. The indemnities contained in this Article X are in addition to and not in lieu of the indemnity provisions contained in the Ancillary Agreements.

ARTICLE XI
GENERAL PROVISIONS

     11.1 Estoppel Certificates. Lessee and Lessor shall, at any time and from time to time upon not less than 20 days prior written request from the other party, execute, acknowledge and deliver to the other a statement in writing (a) certifying that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease, as so modified, is in full force and effect) and the date to which Rent and other charges are paid, and (b) acknowledging that there are not, to the executing party’s knowledge, any uncured defaults on the part of the other party hereunder (or specifying such defaults, if any are claimed). Any such statement may be conclusively relied upon by any prospective purchaser of the Premises or the leasehold evidenced by this Lease or any lender with respect to the Premises or the leasehold evidenced by this Lease. Nothing in this Section 11.1 shall be construed to waive the conditions elsewhere contained in this Lease applicable to assignment or subletting of the Premises by Lessee.

     11.2 Severability. The invalidity or unenforceability of any provision of this Lease, as determined by a court of competent jurisdiction, shall in no way affect the validity or enforceability of any other provision hereof.

     11.3 Time of Essence. Time is of the essence in the performance of all obligations falling due hereunder.

     11.4 Captions. The headings to Articles, Sections and other subdivisions of this Lease are inserted for convenience of reference only and will not affect the meaning or interpretation of this Lease.

     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 11.7.

     11.8 Waivers. No waiver or waivers of any breach or default or any breaches or defaults by either Party of any term, condition or liability of or performance by the other party of any duty or obligation hereunder shall be deemed or construed to be a waiver or waivers of subsequent breaches or defaults of any kind, character or description under any circumstance. The acceptance of Rent hereunder by Lessor shall not be a waiver of any preceding breach by Lessee of any provision hereof, other than the failure of Lessee to pay the particular Rent so accepted, regardless of Lessor’s knowledge of such preceding breach at the time of acceptance of such Rent.

     11.9 No Partnership. The relationship between Lessor and Lessee at all times shall remain solely that of landlord and tenant and shall not be deemed a partnership or joint venture.

     11.10 No Third Party Beneficiaries. Subject to the provisions of Article X and Section 11.14 hereof, this Lease inures to the sole and exclusive benefit of Lessor and Lessee, their respective Affiliates, successors, legal representatives, sublessees and assigns, and confers no benefit on any third party.

     11.11 Waiver of Landlord’s Lien. To the extent permitted by Law, Lessor hereby expressly waives any and all liens (constitutional, statutory, contractual or otherwise) upon Lessee’s personal property now or hereafter installed or placed in or on the Premises, which otherwise might exist to secure payment of the sums herein provided to be paid by Lessee to Lessor.

     11.12 Mutual Cooperation; Further Assurances. Upon request by either Party from time to time during the Term, each Party hereto agrees to execute and deliver all such other and additional instruments, notices and other documents and do all such other acts and things as may be reasonably necessary to carry out the purposes of this Lease and to more fully assure the Parties’ rights and interests provided for hereunder. Each of Lessor and Lessee agrees to reasonably cooperate with the other on all matters relating to required Permits and regulatory compliance by either Lessee or Lessor in respect of the Premises so as to ensure continued full operation of the Premises by Lessee pursuant to the terms of this Lease.

     11.13 Recording. Upon the request of Lessor or Lessee, Lessor and Lessee shall execute, acknowledge, deliver and record a “short form” memorandum of this Lease in the form of Exhibit B attached hereto and made a part hereof for all purposes. Promptly upon request by Lessor at any time following the expiration or earlier termination of this Lease, however such termination may be brought about, Lessee shall execute and deliver to Lessor an instrument, in recordable form, evidencing the termination of this Lease and the release by Lessee of all of Lessee’s right, title and interest in and to the Premises existing under and by virtue of this Lease (the “Lessee Release”) and Lessee grants Lessor an irrevocable power of attorney coupled with an interest for the purpose of executing the Lessee Release in the name of the Lessee. This Section 11.13 shall survive the termination of this Lease.

     11.14 Binding Effect. Except as herein otherwise expressly provided, this Lease shall be binding upon and inure to the benefit of the Parties and their respective successors, sublessees and assigns. Nothing in this Section shall be construed to waive the conditions elsewhere contained in this Lease applicable to assignment or subletting of the Premises by the Parties.

     11.15 Choice of Law. The provisions of this Lease shall be governed by and construed in accordance with the laws of the State of Kansas, excluding any conflicts-of-law rule or principle that might require the application of laws of another jurisdiction.

     11.16 Warranty of Peaceful Possession. Lessor covenants and warrants that Lessee, upon paying the Rent reserved hereunder and observing and performing all of the covenants, conditions and provisions on Lessee’s part to be observed and performed hereunder, may peaceably and quietly have, hold, occupy, use and enjoy, and, subject to the terms of this Lease, shall have the full, exclusive, and unrestricted use and enjoyment of, all the Premises during the Term for the purposes permitted herein, and Lessor agrees to warrant and forever defend title to the Premises against the claims of any and all persons whomsoever lawfully claiming or to claim the same or any part thereof.

     11.17 Force Majeure. In the event of Lessor or Lessee being rendered unable, wholly or in part, by Force Majeure to carry out its obligations under this Lease, other than to make payments due hereunder and the obligations under Section 11.16, it is agreed that on such Party’s giving notice and full particulars of such Force Majeure to the other Party as soon as practicable after the occurrence of the cause relied on, then the obligations of the Parties, so far as they are affected by such Force Majeure, shall be suspended during the continuance of any inability so caused but for no longer period, and such cause shall, as far as possible, be remedied with all reasonable dispatch. It is understood and agreed that the settlement of strikes or lockouts shall be entirely within the discretion of the Party having the difficulty, and that the above requirements that any Force Majeure shall be remedied with all reasonable dispatch shall not require the settlement of strikes or lockouts by acceding to the demands of the opposing party when such course is inadvisable in the discretion of the Party having the difficulty. Notwithstanding anything in this Lease to the contrary, inability of a Party to make payments when due, be profitable or to secure funds, arrange bank loans or other financing, obtain credit or have adequate capacity or production (other than for reasons of Force Majeure) shall not be regarded as events of Force Majeure.

     11.18 Survival. All obligations of Lessor and Lessee that shall have accrued under this Lease prior to the expiration or earlier termination hereof shall survive such expiration or termination to the extent the same remain unsatisfied as of the expiration or earlier termination of this Lease. Lessor and Lessee further expressly agree that all provisions of this Lease which contemplate performance after the expiration or earlier termination hereof shall survive such expiration or earlier termination of this Lease.

     11.19 AS IS, WHERE IS. SUBJECT TO ALL OF THE OBLIGATIONS OF LESSOR UNDER THIS LEASE INCLUDING THOSE SET FORTH IN ARTICLE V, ARTICLE X AND SECTION 11.16, LESSEE HEREBY ACCEPTS THE PREMISES “AS IS”, “WHERE IS”, AND “WITH ALL FAULTS”, AND LESSOR MAKES NO REPRESENTATIONS OR WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, UNDER THIS LEASE AS TO THE PHYSICAL CONDITION OF THE PREMISES, INCLUDING THE PREMISES’ MERCHANTABILITY, HABITABILITY, CONDITION, FITNESS, OR SUITABILITY FOR ANY PARTICULAR USE OR PURPOSE.

     11.20 Relocation of Pipelines; Amendment. If Lessor elects to move certain pipelines within the Refinery Site, and such relocation of the pipelines requires relocation of any of the Relevant Assets, then this Agreement shall continue in full force and effect; provided, however, the Parties shall execute an amendment hereto reflecting the new location(s) of the Relevant Assets.

     11.21 Option. Following the termination or expiration of the Throughput Agreement, including any renewal, extension, or replacement agreement thereof subject to Section 7 of the Throughput Agreement, Lessor shall have an option, and Lessee hereby grants such option, to purchase the Relevant Assets at a cost equal to the fair market value thereof, as reasonably determined by Lessor and Lessee. In the event that Lessor and Lessee cannot agree as to the fair market value of the Relevant Assets, each party shall select a qualified appraiser. The two appraisers shall give their opinion of the fair market value of the Relevant Assets within 20 days after their retention. In the event the opinions of the two appraisers differ and, after good faith efforts over the succeeding 20-day period, they cannot mutually agree, the appraisers shall immediately and jointly appoint a third qualified appraiser. The third appraiser shall immediately (within five days) choose either the determination of Lessor’s appraiser or Lessee’s appraiser and such choice of this third appraiser shall be final and binding on Lessor and Lessee. Each party shall pay its own costs for its appraiser. Following the determination of the fair market value of the Relevant Assets by the appraisers, the parties shall equally share the costs of any third appraiser. Upon Lessor’s exercise of the option granted pursuant to this Section, Lessor and Lessee shall cooperate to convey the Relevant Assets from Lessee to Lessor. The terms and conditions of this Section 11.21 shall survive the termination or expiration of this Agreement or the Throughput Agreement. If Lessor chooses to exercise its option granted pursuant to this Section, the sale of the Relevant Assets shall be subject to the receipt of any consents or waivers required pursuant to the Second Amended and Restated Credit Agreement, dated as of February 14, 2011 (the “Credit Agreement”), among Holly Energy Partners — Operating, L.P., Wells Fargo Bank, N.A., individually and as Administrative Agent, Union Bank, N.A., as administrative agent under the Prior Credit Agreement (as defined in the Credit Agreement) and syndication agent, BBVA Compass Bank and U.S. Bank, N.A., as co-documentation agents, and each of the Lenders (as defined in the Credit Agreement), as such agreement may be amended, restated, otherwise modified or refinanced from time to time.
