     Section 2. Agreement to Use Services Relating to Roadrunner Pipeline.

     The Parties intend to be strictly bound by the terms set forth in this Agreement, which sets forth revenues to HEP Operating to be paid by Navajo Refining and requires HEP Operating to provide certain Crude Oil transportation services to Navajo Refining. The principal objective of HEP Operating is for Navajo Refining to meet or exceed its obligations with respect to the Minimum Pipeline Revenue Commitment. The principal objective of Navajo Refining is for HEP Operating to provide services to Navajo Refining in a manner that enables Navajo Refining to transport Crude Oil on the Roadrunner Pipeline.

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

     (i) Subject to Section 4, Navajo Refining shall pay HEP Operating throughput fees associated with the Roadrunner Pipeline that will satisfy the Minimum Pipeline Revenue Commitment in exchange for HEP Operating providing Navajo Refining a minimum of 40,000 barrels per day of aggregate capacity in the Roadrunner Pipeline. In the event that any third party transports Crude Oil on the Roadrunner Pipeline for ultimate delivery to Holly or any of its subsidiaries and such third party pays throughput fees equal to or greater than the Pipeline Base Tariff for each such barrel of Crude Oil transported on the Roadrunner Pipeline for ultimate delivery to Holly or any of its subsidiaries (“Qualified Third-Party Throughput”), then revenues paid to HEP Operating by such third party for such Qualified Third-Party Throughput shall be credited towards the Minimum Pipeline Revenue Commitment hereunder. The “Minimum Pipeline Revenue Commitment” shall be an amount of revenue to HEP Operating for each Contract Quarter determined by multiplying the Minimum Pipeline Throughput by the Pipeline Base Tariff, as such Pipeline Base Tariff may be revised pursuant to Section 2(a)(iii). Notwithstanding the foregoing, in the event that the Effective Time is any date

Pipeline Throughput Agreement (Roadrunner)

other than the first day of a Contract Quarter, then the Minimum Pipeline 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) If the average throughput for any Contract Quarter (including Qualified Third-Party Throughput) exceeds the Minimum Pipeline Throughput attributable to such Contract Quarter, then for each throughput barrel in excess of the Minimum Pipeline Throughput, Navajo Refining shall pay HEP Operating throughput fees in the amount of the Pipeline Incentive Tariff as such amount may be revised pursuant to Section 2(a)(iii).

     (iii) The Pipeline Base Tariff and Pipeline Incentive Tariff shall be adjusted on July 1 of each calendar year commencing on July 1, 2011, 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. The series ID is WPUSOP3000 as of September 7, 2009 – 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 Base Tariff or Pipeline Incentive Tariff. Notwithstanding anything to the contrary herein, in the event that the PPI for any given calendar year increases by more than three percent (3%), then the Pipeline Base Tariff and Pipeline Incentive Tariff will be increased by a percentage equal to three percent (3%) plus one-half of the PPI increase in excess of three percent (3%) for such calendar year. If the above index is no longer published, then Navajo Refining and HEP Operating 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 Base Tariff and Pipeline Incentive Tariff. If Navajo Refining and HEP Operating are unable to agree, a new index will be determined by binding arbitration in accordance with Section 12(e), and the same method of adjustment for increases in the new index shall be used to calculate increases in the Pipeline Base Tariff and Pipeline Incentive Tariff. To evidence the Parties’ agreement to each adjusted Pipeline Base Tariff and Pipeline 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.

     (iv) If Navajo Refining is unable to transport on the Roadrunner Pipeline the volumes of Crude Oil required to meet the Minimum Pipeline Revenue Commitment as a result of HEP Operating’s operational difficulties, prorationing, or the inability to provide sufficient capacity for the Minimum Pipeline Throughput, then the Minimum Pipeline Revenue Commitment applicable to the Contract Quarter during which Navajo Refining is unable to transport such volumes of Crude Oil will be reduced by an amount equal to: (A) the volume of Crude Oil that Navajo Refining was unable to transport on the

Pipeline Throughput Agreement (Roadrunner)

Roadrunner Pipeline (but not to exceed the Minimum Pipeline Throughput), as a result of HEP Operating’s operational difficulties, prorationing or inability to provide sufficient capacity on the Roadrunner Pipeline to achieve the Minimum Pipeline Throughput, multiplied by (B) the Pipeline Base Tariff. This Section 2(a)(iv) shall not apply in the event HEP Operating gives notice of a Force Majeure event in accordance with Section 4, in which case the Minimum Pipeline Revenue Commitment shall be suspended in accordance with and as provided in Section 4.

     (b) Volumetric Gains and Losses. Navajo Refining shall, during the Term, (i) absorb all volumetric gains in the Roadrunner Pipeline, and (ii) be responsible for all volumetric losses in the Roadrunner Pipeline up to a maximum of 0.5%. HEP Operating shall be responsible for all volumetric losses in excess of 0.5% in the Roadrunner Pipeline during the Term

     (c) Obligations of HEP Operating. During the Term and subject to the terms and conditions of this Agreement, including Section 12(b), HEP Operating agrees to: (i) own or lease, operate and maintain (directly or through a subsidiary) the Roadrunner Pipeline and all related assets necessary to handle the Crude Oil from Navajo Refining; (ii) provide the services required under this Agreement and perform all operations relating to the Roadrunner Pipeline including, but not limited to, interaction with third party pipelines; and (iii) maintain adequate property and liability insurance covering the Roadrunner Pipeline and any related assets owned by HEP Operating and necessary for the operation of the Roadrunner Pipeline. Notwithstanding the preceding sentence, subject to Section 12(b) of this Agreement and Article V of the Omnibus Agreement, HEP Operating is free to sell any of its assets, including assets that provide services under this Agreement, and Navajo Refining is free to merge with another entity and to sell all of its assets or equity to another entity at any time.

     (d) Drag Reducing Agents and Additives. If HEP Operating determines that adding drag reducing agents (“DRA”) to the Crude Oil is reasonably required to move Crude Oil in the quantities necessary to meet Navajo Refining’s schedule or as may be otherwise be required to safely move such quantities of Crude Oil, HEP Operating shall provide Navajo Refining with an analysis of the proposed cost and benefits thereof. In the event that Navajo Refining agrees to use such additives as proposed by HEP Operating, Navajo Refining shall reimburse HEP Operating for the costs of adding any DRA to the Crude Oil.

     (e) Change in Roadrunner Pipeline Direction; Product Service or Origination and Destination. Without Navajo Refining’s prior written consent, HEP Operating shall not (i) reverse the direction of the Roadrunner Pipeline; (ii) change, alter or modify the product service of the Roadrunner Pipeline; or (iii) change, alter or modify the origination or destination of the Roadrunner Pipeline; provided, however, that HEP Operating may take any necessary emergency action to prevent or remedy a release of Crude Oil from the Roadrunner Pipeline without obtaining the consent required by this Section 2(e). Navajo Refining shall have the right to reverse the direction of the Roadrunner Pipeline if Navajo Refining agrees to (i) reimburse HEP Operating for the additional costs and expenses incurred by HEP Operating as a result of such change in direction (both to reverse and re-reverse); (ii) reimburse the HEP Operating for all costs arising out of HEP Operating’s inability to perform under any transportation service contract due to the reversal of the direction of the Roadrunner Pipeline; and (iii) pay the Pipeline

Pipeline Throughput Agreement (Roadrunner)

Base Tariff and Pipeline Incentive Tariff set forth on Schedule I, as it may be amended from time-to-time in accordance with this Agreement, for any such flow reversal.

     (f) Notification of Utilization. Upon request by HEP Operating, Navajo Refining will provide to HEP Operating written notification of Navajo Refining’s reasonable good faith estimate of their anticipated future utilization of the Roadrunner Pipeline as soon as reasonably practicable after receiving such request.

     (g) Scheduling and Accepting Movement. HEP Operating will use its reasonable commercial efforts to schedule movement and accept movements of Crude Oil in a manner that is consistent with the historical dealings between the Parties, as such dealings may change from time to time.

     (h) Taxes. Navajo Refining will pay all taxes, import duties, license fees and other charges by any Governmental Authority levied on or with respect to the Crude Oil handled by Navajo Refining for transportation by HEP Operating. Should any Party be required to pay or collect any taxes, duties, charges and or assessments pursuant to any Applicable Law or authority now in effect or hereafter to become effective which are payable by the any other Party pursuant to this Section 2(h) the proper Party shall promptly reimburse the other Party therefor.

     (i) Timing of Payments. Navajo Refining will make payments to HEP Operating by electronic payment with immediately available funds on a monthly basis during the Term with respect to services rendered or reimbursable costs or expenses incurred by HEP Operating under this Agreement in the prior month. Payments not received by HEP Operating on or prior to the applicable payment date will accrue interest at the Prime Rate from the applicable payment date until paid.

     (j) Increases in Tariff Rates. If new Applicable Laws are enacted that require HEP Operating to make capital expenditures with respect to the Roadrunner Pipeline, HEP Operating may amend the Pipeline Base Tariff in order to recover HEP Operating’s cost of complying with these Applicable Laws (as determined in good faith and including a reasonable return); provided, however, that HEP Operating may not amend the Pipeline Base Tariff pursuant to this Section 2(j) unless and until HEP Operating has made capital expenditures of $1,000,000.00 in the aggregate with respect to the Roadrunner Pipeline in order to comply with such new Applicable Laws. Navajo Refining and HEP Operating shall use their reasonable commercial efforts to comply with these Applicable Laws, and shall negotiate in good faith to mitigate the impact of these Applicable Laws and to determine the amount of the new tariff rates. If Navajo Refining and HEP Operating are unable to agree on the amount of the new tariff rates that HEP Operating will charge, such tariff rates will be determined by binding arbitration in accordance with Section 12(e). Schedule I or any other applicable exhibit or schedule to this Agreement will be updated, amended or revised, as applicable, in accordance with this Agreement to reflect any changes in tariff rates agreed to in accordance with this Section 2(j).

     Section 3. Agreement to Remain Shipper

     With respect to any Crude Oil that is transported in the Roadrunner Pipeline, Navajo Refining agrees that it will continue acting in the capacity of the shipper of any such Crude Oil

Pipeline Throughput Agreement (Roadrunner)

for its own account at all times that such Crude Oil is being transported in the Roadrunner Pipeline.

     Section 4. Force Majeure

     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 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. Navajo Refining 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 HEP Operating or Navajo Refining 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 HEP Operating or Navajo Refining by providing written notice thereof to the other Party.

     Section 5. Agreement Not to Challenge Tariffs

     Navajo Refining agrees to any tariff rate changes for the Roadrunner Pipeline in accordance with this Agreement. Navajo Refining agrees (a) not to challenge, nor to cause their Affiliates to challenge, nor to encourage or recommend to any other Person that it challenge, or voluntarily assist in any way any other Person in challenging, in any forum, tariffs (including joint tariffs) of HEP Operating that HEP Operating has filed or may file containing rates, rules or regulations that are in effect at any time during the Term and regulate the transportation of the Crude Oil, and (b) not to protest or file a complaint, nor cause their Affiliates to protest or file a complaint, nor encourage or recommend to any other Person that it protest or file a complaint, or voluntarily assist in any way any other Person in protesting or filing a complaint, with respect to regulatory filings that the HEP Operating has made or may make at any time during the Term to change tariffs (including joint tariffs) for transportation of Crude Oil in each case so long as such tariffs, regulatory filings or rates changed do not conflict with the terms of this Agreement.

     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 December 1, 2024, unless extended by written mutual agreement of the Parties or as set forth in Section 7 (the “Term).

quarterly basis for the purposes of this Section 9. The Deficiency Notice shall (i) specify in reasonable detail the nature of any deficiency and (ii) specify the approximate dollar amount that HEP Operating believes would have been paid by Navajo Refining to HEP Operating if Navajo Refining had complied with its obligations pursuant to Section 2(a)(i) (the “Deficiency Payment”). Navajo Refining shall pay the Deficiency Payment to HEP Operating upon the later of: (A) ten (10) days after their receipt of the Deficiency Notice and (B) thirty (30) days following the end of the related Contract Quarter.

     (b) If Navajo Refining disagrees with the Deficiency Notice, then, following the payment of the undisputed portion of the Deficiency Payment to HEP Operating, if any, Navajo Refining shall send written notice thereof regarding the disputed portion of the Deficiency Payment to HEP Operating and a senior officer of Holly (on behalf of Navajo Refining) and a senior officer of the Partnership (on behalf of HEP Operating) 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 Deficiency Notice. During the 30-day period following the payment of the Deficiency Payment, Navajo Refining shall have access to the working papers of HEP Operating relating to the Deficiency Notice. If such differences are not resolved within thirty (30) days following Navajo Refining’s receipt of the Deficiency Notice, Navajo Refining and HEP Operating shall, within forty-five (45) days following Navajo Refining’s receipt of the Deficiency Notice, submit any and all matters which remain in dispute and which were properly included in the Deficiency Notice to arbitration in accordance with Section 12(e).

     (c) If it is finally determined pursuant to this Section 9 that Navajo Refining is required to pay any or all of the disputed portion of the Deficiency Payment, Navajo Refining shall promptly pay such amount to HEP Operating, together with interest thereon at the Prime Rate, in immediately available funds.

     (d) The fact that Navajo Refining has exceeded or fallen short of the Minimum Pipeline Revenue Commitment (after taking into account Qualified Third-Party Throughput) with respect to any Contract Quarter shall not be considered in determining whether Navajo Refining meets, exceeds or falls short of the Minimum Pipeline Revenue Commitment (after taking into account Qualified Third-Party Throughput) with respect to any other Contract Quarter, and the amount of any such excess or shortfall shall not be counted towards or against the Minimum Pipeline Revenue Commitment with respect to any other Contract Quarter.

     Section 10. Right of First Refusal. The Parties acknowledge the right of first refusal of Holly with respect to the Roadrunner Pipeline as provided in the Omnibus Agreement.

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, 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, Navajo Refining, HEP Operating 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 Navajo Refining (in the case of any assignment by HEP Operating) or HEP Operating (in the case of any assignment by Navajo Refining), in each case,

Pipeline Throughput Agreement (Roadrunner)

such consent is not to be unreasonably withheld or delayed; provided, however, that (i) HEP Operating may make such an assignment (including a partial pro rata assignment) to an Affiliate of HEP Operating without Navajo Refining’s consent, (ii) Navajo Refining may make such an assignment (including a pro rata partial assignment) to an Affiliate of Navajo Refining without HEP Operating’s consent, (iii) Navajo Refining may make a collateral assignment of their rights and obligations hereunder, and (iv) HEP Operating may make a collateral assignment of their rights hereunder and/or grant a security interest in its rights and obligations hereunder to a bona fide third party lender or debt holder, or trustee or representative for any of them, without Navajo Refining’s consent, if such third party lender, debt holder or trustee shall have executed and delivered to Navajo Refining a non-disturbance agreement in such form as is reasonably satisfactory to Navajo Refining and such third party lender, debt holder or trustee. 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 12(e) and the Commercial Arbitration Rules or the Federal Arbitration Act, the terms of this Section 12(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 Navajo Refining, HEP Operating or any of their Affiliates and (ii) have not less than seven (7) years experience in the petroleum transportation industry. The hearing will be

Pipeline Throughput Agreement (Roadrunner)

conducted in Dallas, Texas and commence within thirty (30) days after the selection of the third arbitrator. Navajo Refining, HEP Operating 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 Navajo Refining, HEP Operating 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.
