Section 2.    Agreement to Use Services Relating to Pipeline Delivery, Tankage and Loading Rack.

The Parties intend to be strictly bound by the terms set forth in this Agreement, which sets forth revenues to El Dorado Logistics to be paid by Frontier El Dorado and requires El Dorado Logistics to provide certain transportation, storage and loading services to Frontier El Dorado. The principal objective of El Dorado Logistics is for Frontier El Dorado to meet or exceed its obligations with respect to the Minimum Pipeline Delivery Revenue Commitment, to meet or exceed its obligations with respect to the Minimum Tankage Revenue Commitment, and to meet or exceed its obligations with respect to the Minimum Loading Rack Revenue Commitment. The principal objective of Frontier El Dorado is for El Dorado Logistics to provide services to Frontier El Dorado in a manner that enables Frontier El Dorado to operate the Refinery.

(a)    Minimum Pipeline Delivery Revenue Commitment. During the Term and subject to the terms and conditions of this Agreement, Frontier El Dorado agrees as follows:

(i)    Subject to Section 4, Frontier El Dorado shall pay El Dorado Logistics throughput fees for pipeline delivery services that will satisfy the Minimum Pipeline Delivery Revenue Commitment in exchange for El Dorado Logistics providing Frontier El Dorado a minimum of 120,000 barrels per day of aggregate delivery capacity from the Tankage. The “Minimum Pipeline Delivery Revenue Commitment” shall be an amount of revenue to El Dorado Logistics for each Contract Quarter determined by multiplying the Minimum Pipeline Delivery Throughput by the Pipeline Delivery Base Tariff as such Pipeline Delivery Base Tariff may be revised pursuant to Section 2(a)(iii) or Section 2(m). Notwithstanding the foregoing, in the event that the Closing Date is any date other than the first day of a Contract Quarter, then the Minimum Pipeline Delivery Revenue Commitment for the initial Contract Quarter shall be prorated based upon the number of days actually in such contract quarter and the initial Contract Quarter.

(ii)    Pipeline delivery throughput shall be determined by the shipments of Products by pipeline (and not over the Loading Racks) by the Refinery. Frontier El Dorado will pay the Pipeline Delivery Base Tariff for each throughput barrel up to and including the Pipeline Delivery Incentive Tariff Threshold. If the average throughput for any Contract Quarter exceeds the Pipeline Delivery Incentive Tariff Threshold attributable to such Contract Quarter then, for each throughput barrel in excess of the Pipeline Delivery Incentive Tariff Threshold, Frontier El Dorado shall pay El Dorado Logistics throughput fees in the amount of the Pipeline Delivery Incentive Tariff as such amount may be revised pursuant to Section 2(a)(iii) or Section 2(m).

(iii)    The Pipeline Delivery Base Tariff and Pipeline Delivery Incentive Tariff shall be adjusted on July 1 of each calendar year commencing on July 1, 2012, by an amount

equal to the upper change in the annual change rounded to four decimal places of the Producers Price Index-Commodities-Finished Goods, (PPI), et al. (“PPI”), produced by the U.S. Department of Labor, Bureaus of Labor Statistics; provided that neither the Pipeline Delivery Base Tariff nor the Pipeline Delivery Incentive Tariff shall ever be increased by more than 3% for any such calendar year. The series ID is WPUSOP3000 as of June 1, 2011 – located at http://www.bls.gov/data/. The change factor shall be calculated as follows: annual PPI index (most current year) less annual PPI index (most current year minus 1) divided by annual PPI index (most current year minus 1). An example for year 2009 change is: [PPI (2008) – PPI (2007)] / PPI (2007) or (177.1 – 166.6) / 166.6 or .063 or 6.3%. If the PPI index change is negative in a given year then there will be no change in the Pipeline Delivery Base Tariff or Pipeline Delivery Incentive Tariff. If the above index is no longer published, then Frontier El Dorado and El Dorado Logistics 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 Pipeline Delivery Base Tariff and Pipeline Delivery Incentive Tariff. If Frontier El Dorado and El Dorado Logistics are unable to agree, a new index will be determined by binding arbitration in accordance with Section 13(e), and the same method of adjustment for increases in the new index shall be used to calculate increases in the Pipeline Delivery Base Tariff and Pipeline Delivery Incentive Tariff. To evidence the Parties’ agreement to each adjusted Pipeline Delivery Base Tariff and Pipeline Delivery Incentive Tariff, the Parties shall execute an amended, modified, revised or updated Schedule I and attach it to this Agreement. Such amended, modified, revised or updated Schedule I shall be sequentially numbered (e.g. Schedule I-1, Schedule I-2, etc.), dated and appended as an additional schedule to this Agreement and shall replace the prior version of Schedule I in its entirety after its date of effectiveness.

(iv)    If Frontier El Dorado is unable to transport the volumes of Products required to meet the Minimum Pipeline Delivery Revenue Commitment as a result of El Dorado Logistics’ operational difficulties, prorationing, or the inability to provide sufficient capacity for the Minimum Pipeline Delivery Throughput, then the Minimum Pipeline Delivery Revenue Commitment applicable to the Contract Quarter during which Frontier El Dorado is unable to transport such volumes of Products will be reduced by an amount equal to: (A) the volume of Products that Frontier El Dorado was unable to transport (but not to exceed the Minimum Pipeline Delivery Throughput), as a result of El Dorado Logistics’ operational difficulties, prorationing or inability to provide sufficient capacity to achieve the Minimum Pipeline Delivery Throughput, multiplied by (B) the Pipeline Delivery Base Tariff. This Section 2(a)(iv) shall not apply in the event El Dorado Logistics gives notice of a Force Majeure event in accordance with Section 4, in which case the Minimum Pipeline Delivery Revenue Commitment shall be suspended in accordance with and as provided in Section 4.

(b)    Minimum Tankage Revenue Commitment; Tankage Tariffs. During the Term and subject to the terms and conditions of this Agreement, Frontier El Dorado agrees as follows:

(i)    Subject to Section 4, Frontier El Dorado shall pay El Dorado Logistics throughput fees associated with the Tankage that will satisfy the Minimum Tankage Revenue

Commitment in exchange for El Dorado Logistics providing Frontier El Dorado a minimum of 140,000 bpd barrels of aggregate capacity in the Tankage. The “Minimum Tankage Revenue Commitment” shall be an amount of revenue to El Dorado Logistics for each Contract Quarter determined by multiplying the Minimum Tankage Throughput by the Tankage Base Tariff applicable to such Contract Quarter as such Tankage Base Tariff may be revised pursuant to Section 2(b)(iii), Section 2(b)(iv), Section 2(m), and Section 2(n). Notwithstanding the foregoing, in the event that the Closing Date is any date other than the first day of a Contract Quarter, then the Minimum Tankage Revenue Commitment for the initial Contract Quarter shall be prorated based upon the number of days actually in such contract quarter and the initial Contract Quarter. In the event that the Tankage Base Tariff is changed and such change is effective on any date other than the first day of a Contract Quarter, then the Minimum Tankage Revenue Commitment for such Contract Quarter shall be calculated by applying the prior Tankage Base Tariff to the portion of the Contract Quarter occurring before the date of the change and the Tankage Base Tariff as changed to the portion of the Contract Quarter occurring on and after the date of the change. Subject to (i) any Applicable Law and (ii) technical specifications of the Tankage, Frontier El Dorado may request that El Dorado Logistics change the service of any of the Tankage from storage of one Product to storage of a different Product. If El Dorado Logistics agrees to such request, Frontier El Dorado shall indemnify and hold El Dorado Logistics harmless from and against all costs and expenses associated with any such changing of service including but not limited to costs of complying with any Applicable Law affecting such change of service.

(ii)    Tankage throughput shall be determined by the sum of Products shipped by the Refinery but not including shipments of coke and sulfur. For the avoidance of doubt, no Tankage throughput fees shall be paid for movements of Products within the Refinery. Frontier El Dorado shall pay the Tankage Base Tariff for each throughput barrel up to and including the Tankage Incentive Tariff Threshold. If the average throughput for any Contract Quarter exceeds the Tankage Incentive Tariff Threshold attributable to such Contract Quarter then, for each throughput barrel in excess of the Tankage Incentive Tariff Threshold, Frontier El Dorado shall pay El Dorado Logistics throughput fees in the amount of the Tankage Incentive Tariff as such amount may be revised pursuant to Section 2(b)(iii) or Section 2(m).

(iii)    The Tankage Base Tariff and Tankage Incentive Tariff shall each be adjusted on July 1 of each calendar year commencing on July 1, 2012, by an amount equal to the upper change in the annual change rounded to four decimal places of the PPI following the same procedure as set forth in Section 2(a)(iii) above (including the provisions regarding binding arbitration); provided that the Tankage Base Tariff and Tankage Incentive Tariff shall never be increased by more than 3% for any such calendar year. To evidence the Parties’ agreement to each adjusted Tankage Base Tariff and Tankage Incentive Tariff, the Parties shall execute an amended, modified, revised or updated Schedule II and attach it to this Agreement. Such amended, modified, revised or updated Schedule II shall be sequentially numbered (e.g. Schedule II-1, Schedule II-2, etc.), dated and appended as an additional schedule to this Agreement and shall replace the prior version of Schedule II in its entirety after its date of effectiveness.

(iv)    El Dorado Logistics shall use its commercially reasonable efforts to construct the New Tank in accordance with the specifications set forth on Schedule V; provided that if El Dorado Logistics should fail to complete the New Tank or if the New Tank Commencement Date does not occur for the New Tank for a reason related to the fault of El Dorado Logistics or a matter that is within or under the control of El Dorado Logistics, El Dorado Logistics shall bear all costs, liabilities and expenses with respect to such incomplete New Tank, and if El Dorado Logistics should fail to complete the New Tank or if the New Tank Commencement Date does not occur for the New Tank for any other reason, Frontier El Dorado shall reimburse El Dorado Logistics for all costs, liabilities and expenses incurred by El Dorado Logistics with respect to such incomplete New Tank. Promptly following the New Tank Commencement Date, El Dorado Logistics will deliver a written certification to Frontier El Dorado certifying the final aggregate construction costs for the New Tank (the “Final Construction Cost”). From and after the New Tank Commencement Date, the Tankage Base Tariff shall be increased by an amount per barrel equal to:

For example, if the Final Construction Costs = $1,500,000, the per barrel increase in the Tankage Base Tariff would be calculated as follows:

$1,500,000/(0.9 x 8.1928 x 140,000 x 365) = $0.0040

Additionally, promptly following the New Tank Commencement Date, the Parties shall execute an amended Exhibit B reflecting the addition of the New Tank and attach it to this Agreement. Such amended Exhibit B shall be numbered Exhibit B-1, dated and appended as an additional schedule to this Agreement and shall replace the prior version of Exhibit B in its entirety after its date of effectiveness.

(v)    If Frontier El Dorado is unable to deliver to the Tankage the volumes of Refined Products required to meet the Minimum Tankage Revenue Commitment as a result of El Dorado Logistics’ operational difficulties, prorationing or the inability to provide sufficient capacity, then the Minimum Tankage Revenue Commitment applicable to the Contract Quarter during which Frontier El Dorado is unable to deliver such volumes of Refined Products will be reduced by an amount equal to: (A) the volume of Refined Products that Frontier El Dorado was unable to deliver to the Tankage (but not to exceed the Minimum Tankage Throughput), as a result of El Dorado Logistics’ operational difficulties, prorationing or inability to provide sufficient capacity to achieve the Minimum Tankage Throughput, multiplied by (B) the Tankage Base Tariff. This Section 2(b)(v) shall not apply in the event El Dorado Logistics gives notice of a Force Majeure event in accordance with Section 4, in which case the Minimum Tankage Revenue Commitment shall be suspended in accordance with and as provided in Section 4.

(c)    Minimum Loading Rack Revenue Commitment.

(i)    Subject to Section 4, Frontier El Dorado shall pay El Dorado Logistics throughput fees associated with the Loading Racks that will satisfy the Minimum Loading Rack Revenue Commitment in exchange for El Dorado Logistics providing Frontier El Dorado a minimum of 20,000 barrels per day of aggregate capacity at the Loading Racks. The “Minimum Loading Rack Revenue Commitment” shall be an amount of revenue to El Dorado Logistics for each Contract Quarter determined by multiplying the Minimum Loading Rack Throughput by the Loading Rack Tariff as such Loading Rack Tariff may be revised pursuant to Section 2(c)(ii) or Section 2(m). Frontier El Dorado will pay El Dorado Logistics the Loading Rack Tariff for all quantities of Products or other materials loaded at the Loading Racks or the asphalt loading rack and any Products or other materials shipped using the weight scales. Notwithstanding the foregoing, in the event that the Closing Date is any date other than the first day of a Contract Quarter, then the Minimum Loading Rack Revenue Commitment for the initial Contract Quarter shall be prorated based upon the number of days actually in such contract quarter and the initial Contract Quarter.

(ii)    The Loading Rack Tariff shall be adjusted on July 1 of each calendar year commencing on July 1, 2012, by an amount equal to the upper change in the annual change rounded to four decimal places of the PPI following the same procedure as set forth in Section 2(a)(iii) above (including the provisions regarding binding arbitration); provided that the Loading Rack Tariff shall never be increased by more than 3% for any such calendar year. To evidence the Parties’ agreement to each adjusted Loading Rack Tariff, the Parties shall execute an amended, modified, revised or updated Schedule III and attach it to this Agreement. Such amended, modified, revised or updated Schedule III shall be sequentially numbered (e.g. Schedule III-1, Schedule III-2, etc.), dated and appended as an additional schedule to this Agreement and shall replace the prior version of Schedule III in its entirety after its date of effectiveness.

(iii)    If Frontier El Dorado is unable to load at the Loading Rack the volumes of Products, in the aggregate, required to meet the Minimum Loading Rack Revenue Commitment as a result of El Dorado Logistics’ operational difficulties, prorationing or the inability to provide sufficient capacity, then the Minimum Loading Rack Revenue Commitment applicable to the Contract Quarter during which Frontier El Dorado is unable to load such volumes of Products will be reduced for such period of time by an amount equal to: (A) the volume of Products, in the aggregate, that Frontier El Dorado was unable to load at the Loading Rack (but not to exceed the Minimum Loading Rack Throughput), as a result of El Dorado Logistics’ operational difficulties, prorationing or inability to provide sufficient capacity to achieve the Minimum Loading Rack Throughput, multiplied by (B) the Loading Rack Tariff. This Section 2(c)(iii) shall not apply in the event El Dorado Logistics gives notice of a Force Majeure event in accordance with Section 4, in which case the Minimum Loading Rack Revenue Commitment shall be suspended in accordance with and as provided in Section 4.

In the event that such aggregate operating expenses are less than the Assumed OPEX, El Dorado Logistics shall decrease the Tankage Base Tariff by the amount necessary to decrease the Minimum Tankage Revenue Commitment by an

amount equal to the difference between the Assumed OPEX and such actual operating expenses for the remainder of the Term, and the Parties shall execute an amended, modified, revised or updated Schedule II reflecting such aggregate operating expenses as the new Assumed OPEX. In the event that the PPI increase for any given year is greater than seven percent (7%), then, in addition to any other applicable increases during such year, El Dorado Logistics shall increase the Tankage Base Tariff by an additional amount necessary to increase the Minimum Tankage Revenue Commitment by the OPEX Recovery Amount. Such OPEX Recovery Amount shall be added to the then-current Assumed OPEX, and the Parties shall execute an amended, modified, revised or updated Schedule IV reflecting the addition of such OPEX Recovery Amount to the Assumed OPEX. No operating expenses related solely to the New Tank shall be considered when calculating the OPEX Recovery Amount.

(o)    Tank Inspection and Repairs. Frontier El Dorado will reimburse El Dorado Logistics for the cost of performing the first API 653 inspection on each of the respective tanks included in the Tankage and any repairs or tests or consequential remediation that may be required to be made to such assets as a result of any discovery made during such inspection; provided, however, that if a tank is two (2) years old or less or has been inspected and repaired during the last twelve months prior to the Closing Date, then El Dorado Logistics will bear the cost of any API 653 inspection and any required repair, testing or consequential remediation of such tank. In addition, El Dorado Logistics will be responsible for the costs of painting any tanks included in the Tankage that require it.

(p)    Removal of Tank from Service. The Parties agree that if they mutually determine to remove a tank included in the Tankage from service, then El Dorado Logistics will not be required to utilize, operate or maintain such tank or provide the services required under this Agreement with respect to such tank (and there will be no adjustment to the Minimum Tankage Revenue Commitment).

(q)    Notice of Violation under Environmental Permits; RCRA Order. The Parties agree that, because El Dorado Logistics or one of its Affiliates is operating certain assets at the Refinery pursuant to permits, licenses, registrations or other operating authorizations (collectively, “Environmental Permits”) issued to HollyFrontier or one of its Affiliates under Environmental Laws, in the event that HollyFrontier or one of such Affiliates receives a notice of violation or enforcement action from the U.S. Environmental Protection Agency or a state agency alleging non-compliance with such Environmental Permits, and such non-compliance relates to the El Dorado Assets, then El Dorado Logistics (and not HollyFrontier or its Affiliates), will be responsible for responding to any such notice of violation or enforcement action. The applicable HollyFrontier Entity shall have the right, but not the duty, to be fully informed and to participate in the prosecution and/or settlement of any notice of violation or enforcement action relating to the El Dorado Assets. Additionally, the Parties Agree that Frontier El Dorado will retain responsibility for complying with the terms of the RCRA Order, including all obligations that apply or relate to the El Dorado Assets. The Parties acknowledge that any costs, penalties, fines or losses associated with responses to any notices of violation or enforcement action under any such Environmental Permits or the RCRA Order may be the subject of indemnification under the Omnibus Agreement (and nothing in this Section 2(q) shall be deemed to change, amend or expand the Parties’ obligations under such Omnibus Agreement

provisions other than with regard to the obligation to respond to such notice of violation or enforcement). El Dorado Logistics will and will cause its Affiliates to cooperate with and support Frontier El Dorado and its Affiliates in satisfying any applicable compliance and reporting obligations under the RCRA Order or Environmental Permits as they relate to the El Dorado Assets and does hereby authorize Frontier El Dorado to submit all reports, certifications and other compliance related submissions on its behalf in satisfaction of such compliance and reporting obligations. El Dorado Logistics confirms that it has received a copy of the RCRA Order. The Parties agree that, if, as a result of future circumstances or construction, it becomes necessary for the Parties to obtain additional Environmental Permits that relate to assets that will be located at the Refinery but owned by an HEP Entity, and the Parties agree that such Environmental Permit shall be held by or in the name of a HollyFrontier Entity, then such Environmental Permit shall be subject to the provisions of this Section 2(q) to the same extent as if the assets to which such Environmental Permits relate were El Dorado Assets.

(r)    Tank Inspection and Maintenance Plan. At least annually, El Dorado Logistics shall prepare and submit to Frontier El Dorado a tank inspection and maintenance plan (which shall include an inspection plan, a cleaning plan, a waste disposal plan, details regarding scheduling and a budget) for the Tankage. If Frontier El Dorado consents to the submitted plan (which consent shall not be unreasonably withheld or delayed), then El Dorado Logistics shall conduct tank maintenance in conformity with such approved tank maintenance plan (other than any deviations or changes from such plan to which Frontier El Dorado consents (which consent shall not be unreasonably withheld, conditioned or delayed)). El Dorado Logistics will use its commercially reasonable efforts to schedule the activities under such maintenance plan to minimize disruptions to the operations of Frontier El Dorado at the Refinery.

Section 3.    Agreement to Remain Shipper

With respect to any Crude Oil or Products that are transported, stored or handled in connection with any of the El Dorado Assets, Frontier El Dorado agrees that Frontier El Dorado or another HollyFrontier Entity will continue acting in the capacity of the shipper of any such Crude Oil or Products for its own account at all times that such Crude Oil or Products are being transported, stored or handled in such El Dorado Assets.

Section 4.    Notification of Shut-down or Reconfiguration; Force Majeure

(a)    Frontier El Dorado must deliver to El Dorado Logistics at least six months advance written notice of any planned shut down or reconfiguration (excluding planned maintenance turnarounds) of the Refinery or any portion of the Refinery that would reduce the Refinery’s output. Frontier El Dorado will use its commercially reasonable efforts to mitigate any reduction in revenues or throughput obligations under this Agreement that would result from such a shut down or reconfiguration.

(b)    If Frontier El Dorado shuts down or reconfigures the Refinery or any portion of the Refinery (excluding planned maintenance turnarounds) and reasonably believes in good faith that such shut down or reconfiguration will jeopardize its ability to satisfy its Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, or Minimum Loading Rack

Revenue Commitment under this Agreement, then within 90 days of the delivery of the written notice of the planned shut down or reconfiguration, Frontier El Dorado shall (A) propose a new Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, or Minimum Loading Rack Revenue Commitment under this Agreement, as applicable, such that the ratio of the new Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, or Minimum Loading Rack Revenue Commitment, as the case may be, under this Agreement over the anticipated production level following the shut down or reconfiguration will be approximately equal to the ratio of the original Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, or Minimum Loading Rack Revenue Commitment under this Agreement over the original production level and (B) propose the date on which the new Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, or Minimum Loading Rack Revenue Commitment under this Agreement shall take effect. Unless objected to by El Dorado Logistics within 60 days of receipt by El Dorado Logistics of such proposal, such new Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, or Minimum Loading Rack Revenue Commitment under this Agreement shall become effective as of the date proposed by Frontier El Dorado. To the extent that El Dorado Logistics does not agree with Frontier El Dorado’s proposal, any changes in Frontier El Dorado’s obligations under this Agreement, or the date on which such changes will take effect, will be determined by binding arbitration in accordance with Section 13(e). Any applicable exhibit or schedule to this Agreement will be updated, amended or revised, as applicable, in accordance with this Agreement to reflect any change in the Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, or Minimum Loading Rack Revenue Commitment under this Agreement agreed to in accordance with this Section 4(b).

(c)    In the event that any Party is rendered unable, wholly or in part, by a Force Majeure event from performing its obligations under this Agreement for a period of more than thirty (30) consecutive days, then, upon the delivery of notice and full particulars of the Force Majeure event in writing within a reasonable time after the occurrence of the Force Majeure event relied on (“Force Majeure Notice”), the obligations of the Parties, so far as they are affected by the Force Majeure event, shall be suspended for the duration of any inability so caused. Any suspension of the obligations of the Parties as a result of this Section 4(c) shall extend the Term (to the extent so affected) for a period equivalent to the duration of the inability set forth in the Force Majeure Notice. Frontier El Dorado will be required to pay any amounts accrued and due under this Agreement at the time of the Force Majeure event. The cause of the Force Majeure event shall so far as possible be remedied with all reasonable dispatch, except that no Party shall be compelled to resolve any strikes, lockouts or other industrial disputes other than as it shall determine to be in its best interests. In the event a Force Majeure event prevents El Dorado Logistics or Frontier El Dorado from performing substantially all of their respective obligations under this Agreement for a period of more than one (1) year, this Agreement may be terminated by El Dorado Logistics or Frontier El Dorado, by providing written notice thereof to the other Parties.

Section 5.    [Reserved.]

Section 6.    Effectiveness and Term

This Agreement shall be effective as of the Effective Time, and shall terminate at 12:01 a.m. Dallas, Texas, time on October 31, 2026, unless extended by written mutual agreement of the Parties or as set forth in Section 7 (the “Term). The Party(ies) desiring to extend this Agreement pursuant to this Section 6 shall provide prior written notice to the other Parties of its desire to so extend this Agreement; such written notice shall be provided not more than twenty-four (24) months and not less than the later of twelve (12) months prior to the date of termination or ten (10) days after receipt of a written request from another Party (which request may be delivered no earlier than twelve (12) months prior to the date of termination) to provide any such notice or lose such right.

Section 7.    Right to Enter into a New Agreement

(a)    In the event that Frontier El Dorado provides prior written notice to El Dorado Logistics of the desire of Frontier El Dorado to extend this Agreement by written mutual agreement of the Parties, the Parties shall negotiate in good faith to extend this Agreement by written mutual agreement, but, if such negotiations fail to produce a written mutual agreement for extension by a date six months prior to the termination date, then El Dorado Logistics shall have the right to negotiate to enter into one or more pipeline delivery, tankage and loading agreements with one or more third parties to begin after the date of termination; provided, however, that until the end of one year following termination without renewal of this Agreement, Frontier El Dorado will have the right to enter into a new pipeline delivery, tankage and loading agreement with El Dorado Logistics on commercial terms that substantially match the terms upon which El Dorado Logistics proposes to enter into an agreement with a third party for similar services with respect to all or a material portion of the El Dorado Assets. In such circumstances, El Dorado Logistics shall give Frontier El Dorado forty-five (45) days prior written notice of any proposed new pipeline delivery, tankage and loading agreement with a third party, and such notice shall inform Frontier El Dorado of the fee schedules, tariffs, duration and any other terms of the proposed third party agreement and Frontier El Dorado shall have forty-five (45) days following receipt of such notice to agree to the terms specified in the notice or Frontier El Dorado shall lose the rights specified by this Section 7(a) with respect to the assets that are the subject of such notice.

(b)    In the event that Frontier El Dorado fails to provide prior written notice to El Dorado Logistics of the desire of Frontier El Dorado to extend this Agreement by written mutual agreement of the Parties pursuant to Section 6, El Dorado Logistics shall have the right, during the period from the date of Frontier El Dorado’s failure to provide written notice pursuant to Section 6 to the date of termination of this Agreement, to negotiate to enter into a new pipeline delivery, tankage and loading agreement with a third party; provided, however, that at any time during the twelve (12) months prior to the expiration of the Term, Frontier El Dorado will have the right to enter into a new pipeline delivery, tankage and loading agreement with El Dorado Logistics on commercial terms that substantially match the terms upon which El Dorado Logistics proposes to enter into an agreement with a third party for similar services with respect to all or a material portion of the El Dorado Assets. In such circumstances, El Dorado Logistics shall give Frontier El Dorado forty-five (45) days prior written notice of any proposed new pipeline delivery, tankage and loading agreement with a third party, and such notice shall inform Frontier El Dorado of the fee schedules, tariffs, duration and any other terms of the proposed third party agreement and Frontier El Dorado shall have forty-five (45) days following receipt of such notice to agree to the terms specified in

the notice or Frontier El Dorado shall lose the rights specified by this Section 7(b) with respect to the assets that are the subject of such notice.

Section 9.    Deficiency Payments

(a)    As soon as practicable following the end of each Contract Quarter under this Agreement, El Dorado Logistics shall deliver to Frontier El Dorado a written notice (the “Deficiency Notice”) detailing any failure of Frontier El Dorado to meet its minimum revenue commitment obligations under Section 2(a)(i), Section 2(b)(i), or Section 2(c)(i); provided, however, that Frontier El Dorado’s obligations pursuant to the Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, and the Minimum Loading Rack Revenue Commitment shall, in each case, be assessed on a quarterly basis for the purposes of this Section 9. Notwithstanding the previous sentence, any deficiency owed by Frontier El Dorado due to its failure to satisfy the Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, or Minimum Loading Rack Revenue Commitment in any Contract Quarter shall be offset by any revenue owed to El Dorado Logistics in excess of the Minimum Pipeline Delivery Revenue Commitment, Minimum Tankage Revenue Commitment, or Minimum Loading Rack Revenue Commitment for such Contract Quarter. The Deficiency Notice shall (A) specify in reasonable detail the nature of any deficiency and (B) specify the approximate dollar amount that El Dorado Logistics believes would have been paid by Frontier El Dorado to El Dorado Logistics if Frontier El Dorado had complied with its minimum revenue commitment obligations pursuant to Section 2(a)(i), Section 2(b)(i), or Section 2(c)(i), as applicable (the “Deficiency Payment”). Frontier El Dorado shall pay the Deficiency Payment to El Dorado Logistics upon the later of: (1) ten (10) days after their receipt of the Deficiency Notice and (2) thirty (30) days following the end of the related Contract Quarter.

(b)    If Frontier El Dorado disagrees with any Deficiency Notice (the “Disputed Deficiency Notice”), then, following the payment of the undisputed portion of the deficiency payment related to the Disputed Deficiency Notice (the “Disputed Deficiency Payment”) to El Dorado Logistics, if any, Frontier El Dorado shall send written notice thereof regarding the disputed portion of the Disputed Deficiency Notice to El Dorado Logistics, and a senior officer of HollyFrontier (on behalf of Frontier El Dorado) and a senior officer of the Partnership (on behalf of El Dorado Logistics) shall meet or communicate by telephone at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary and shall negotiate in good faith to attempt to resolve any differences that they may have with respect to matters specified in the Disputed Deficiency Notice. During the 30-day period following the receipt of the Disputed Deficiency Notice, Frontier El Dorado shall have access to the working papers of El Dorado Logistics relating to the Disputed Deficiency Notice. If such differences are not resolved within thirty (30) days following Frontier El Dorado’s receipt of the Disputed Deficiency Notice, Frontier El Dorado, on the one hand, and El Dorado Logistics, on the other hand, shall, within forty-five (45) days following Frontier El Dorado’s receipt of the Disputed Deficiency Notice, submit any and all matters which remain in dispute and which were properly included in the Disputed Deficiency Notice to arbitration in accordance with Section 13(e).

(c)    If it is finally determined pursuant to this Section 9 that Frontier El Dorado is required to pay any or all of the disputed portion of the Disputed Deficiency Payment, Frontier El Dorado shall promptly pay such amount to El Dorado Logistics, as applicable, together with interest thereon at the Prime Rate, in immediately available funds.

(d)    The Parties acknowledge and agree that there shall be no carry-over of deficiency payments beyond each Contract Quarter provided for in Section 9(a) with respect to the Minimum Pipeline Delivery Revenue Commitment, the Minimum Tankage Revenue Commitment or the Minimum Loading Rack Revenue Commitment.

Section 10.    Indemnification. The Parties acknowledge the indemnification obligations between the Parties and their Affiliates with respect to the El Dorado Assets provided in the Omnibus Agreement.

Section 11.    Right of First Refusal. The Parties acknowledge the right of first refusal of Frontier El Dorado with respect to the El Dorado Assets provided in the Omnibus Agreement.

Section 12.    Limitation of Damages.

(a)    NOTWITHSTANDING ANYTHING CONTAINED TO THE CONTRARY IN ANY OTHER PROVISION OF THIS AGREEMENT AND EXCEPT FOR CLAIMS MADE BY THIRD PARTIES WHICH SHALL NOT BE LIMITED BY THIS PARAGRAPH, THE PARTIES AGREE THAT THE RECOVERY BY ANY PARTY OF ANY LIABILITIES, DAMAGES, COSTS OR OTHER EXPENSES SUFFERED OR INCURRED BY IT AS A RESULT OF ANY BREACH OR NONFULFILLMENT BY A PARTY OF ANY OF ITS REPRESENTATIONS, WARRANTIES, COVENANTS, AGREEMENTS OR OTHER OBLIGATIONS UNDER THIS AGREEMENT, SHALL BE LIMITED TO ACTUAL DAMAGES AND SHALL NOT INCLUDE OR APPLY TO, NOR SHALL ANY PARTY BE ENTITLED TO RECOVER, ANY INDIRECT, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES (INCLUDING, WITHOUT LIMITATION, ANY DAMAGES ON ACCOUNT OF LOST PROFITS OR OPPORTUNITIES OR BUSINESS INTERRUPTION OR DIMINUTION IN VALUE) SUFFERED OR INCURRED BY ANY PARTY; PROVIDED, HOWEVER, THAT SUCH RESTRICTION AND LIMITATION SHALL NOT APPLY (x) AS A RESULT OF A THIRD PARTY CLAIM FOR SUCH INDIRECT, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES OR (y) TO INDIRECT, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES (INCLUDING, WITHOUT LIMITATION, ANY DAMAGES ON ACCOUNT OF LOST PROFITS OR OPPORTUNITIES OR BUSINESS INTERRUPTION OR DIMINUTION IN VALUE) THAT ARE A RESULT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE BREACHING OR NONFULFILLING PARTY OR ITS AFFILIATES.

Section 13.    Miscellaneous

(a)    Amendments and Waivers. No amendment or modification of this Agreement shall be valid unless it is in writing and signed by the Parties. No waiver of any provision of this Agreement shall be valid unless it is in writing and signed by the Party against whom the waiver is sought to be enforced. Any of the exhibits or schedules to this Agreement may be amended, modified, revised

or updated by the Parties if each of the Parties executes an amended, modified, revised or updated exhibit or schedule, as applicable, and attaches it to this Agreement. Such amended, modified, revised or updated exhibits or schedules shall be sequentially numbered (e.g. Schedule I-1, Schedule I-2, etc.), dated and appended as an additional exhibit or schedule to this Agreement and shall replace the prior exhibit or schedule, as applicable, in its entirety after its date of effectiveness, except as specified therein. No failure or delay in exercising any right hereunder, and no course of conduct, shall operate as a waiver of any provision of this Agreement. No single or partial exercise of a right hereunder shall preclude further or complete exercise of that right or any other right hereunder.

(b)    Successors and Assigns. This Agreement shall inure to the benefit of, and shall be binding upon, Frontier El Dorado, El Dorado Logistics, and their respective successors and permitted assigns. Neither this Agreement nor any of the rights or obligations hereunder shall be assigned without the prior written consent of Frontier El Dorado (in the case of any assignment by El Dorado Logistics) or El Dorado Logistics (in the case of any assignment by Frontier El Dorado), in each case, such consent is not to be unreasonably withheld or delayed; provided, however, that (i) El Dorado Logistics may make such an assignment (including a partial pro rata assignment) to an Affiliate of El Dorado Logistics without Frontier El Dorado’s consent, (ii) Frontier El Dorado may make such an assignment (including a pro rata partial assignment) to an Affiliate of Frontier El Dorado without El Dorado Logistics’ consent, (iii) Frontier El Dorado may make a collateral assignment of its rights and obligations hereunder, and (iv) El Dorado Logistics may make a collateral assignment of its rights hereunder and/or grant a security interest in all or a portion of the El Dorado Assets to a bona fide third party lender or debt holder, or trustee or representative for any of them, without Frontier El Dorado’s consent, if such third party lender, debt holder or trustee shall have executed and delivered to Frontier El Dorado a non-disturbance agreement in such form as is reasonably satisfactory to Frontier El Dorado and such third party lender, debt holder or trustee and Frontier El Dorado executes an acknowledgement of such collateral assignment in such form as may from time to time be reasonably requested. Any attempt to make an assignment otherwise than as permitted by the foregoing shall be null and void. The Parties agree to require their respective successors, if any, to expressly assume, in a form of agreement reasonably acceptable to the other Parties, their obligations under this Agreement.

(c)    Severability. If any provision of this Agreement shall be held invalid or unenforceable by a court or regulatory body of competent jurisdiction, the remainder of this Agreement shall remain in full force and effect.

(d)    Choice of Law. 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.

(e)    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 13(e) and the Commercial Arbitration Rules or the Federal Arbitration Act, the terms of this Section 13(e) 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 any of Frontier El Dorado, El Dorado Logistics, 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. Frontier El Dorado, El Dorado Logistics, 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 Frontier El Dorado, El Dorado Logistics, 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.

(f)    Rights of Limited Partners. The provisions of this Agreement are enforceable solely by the Parties, and no limited partner of the Partnership shall have the right, separate and apart from the Partnership, to enforce any provision of this Agreement or to compel any Party to comply with the terms of this Agreement.

(g)    Further Assurances. In connection with this Agreement and all transactions contemplated by this Agreement, each signatory Party hereto agrees to execute and deliver such additional documents and instruments and to perform such additional acts as may be necessary or appropriate to effectuate, carry out and perform all of the terms, provisions and conditions of this Agreement and all such transactions.

(h)    Headings. Headings of the Sections of this Agreement are for convenience of the Parties only and shall be given no substantive or interpretative effect whatsoever. All references in this Agreement to Sections are to Sections of this Agreement unless otherwise stated.

(i)    No Novation. This Agreement shall be considered an amendment and restatement of the First Amended and Restated El Dorado Throughput Agreement, and the First Amended and

Restated El Dorado Throughput Agreement is hereby ratified, approved and confirmed in every respect, except as amended hereby. This Agreement is not intended to constitute a novation of the First Amended and Restated El Dorado Throughput Agreement and all of the obligations owing by the Parties under the First Amended and Restated El Dorado Throughput Agreement shall continue (from and after the date of this Agreement, as amended hereby).

Section 14.    Guarantee by HollyFrontier

HollyFrontier unconditionally, absolutely, continually and irrevocably guarantees, as principal and not as surety, to El Dorado Logistics the punctual and complete payment in full when due of all amounts due from Frontier El Dorado under the Agreement (collectively, the “Frontier El Dorado Payment Obligations”).

(e)    Reinstatement. The obligations of HollyFrontier under this Section 14 shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment of any of the Frontier El Dorado Payment Obligations is rescinded or must otherwise be returned to Frontier El Dorado or any other entity, upon the insolvency, bankruptcy, arrangement, adjustment, composition, liquidation or reorganization of Frontier El Dorado or such other entity, or for any other reason, all as though such payment had not been made.

(a)    Payment and Performance Guaranty. Each of the Partnership and the Operating Partnership unconditionally, absolutely, continually and irrevocably guarantees, as principal and not as surety, to Frontier El Dorado the punctual and complete payment in full when due of all amounts due from El Dorado Logistics under the Agreement (collectively, the “El Dorado Logistics Payment Obligations”). Each of the Partnership and the Operating Partnership agrees that Frontier El Dorado shall be entitled to enforce directly against the Partnership and the Operating Partnership any of the El Dorado Logistics Payment Obligations.

The obligations of each of the Partnership and the Operating Partnership 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 El Dorado Logistics Payment Obligations or otherwise.
