The principal objective of the Partnership Entities is for the ▇▇▇▇▇ Entities to meet or exceed their obligations with respect to the Minimum Pipeline Revenue Commitment, and to meet their obligations with respect to the Tankage Revenue Commitment and the Roswell Terminal Payment. The principal objective of the ▇▇▇▇▇ Entities is for the Partnership Entities to provide services to the ▇▇▇▇▇ Entities in a manner that enables the ▇▇▇▇▇ Entities to operate their assets in a manner as favorably as their historical practice when the ▇▇▇▇▇ Entities were the owners of the Drop-Down Assets.

     (a) Minimum Pipeline Revenue Commitment. During the Term and subject to the terms and conditions of this Agreement, the ▇▇▇▇▇ Entities agree as follows:

     (i) Subject to Section 3, commencing on the Effective Time, the ▇▇▇▇▇ Entities will ship (1) on the Crude Oil Trunk Pipelines an amount of Crude Oil in the aggregate having a quantity and consistency that will produce revenue to the Partnership Entities in an amount at least equal to $13,552,450 annually (the “Minimum Trunk Pipeline Revenue Commitment”); (2) on the Crude Oil Gathering Pipelines and store at the Artesia Crude Oil Pipeline Tankage and the Lovington Crude Oil Pipeline Tankage, an amount of Crude Oil in the aggregate that will produce revenue to the Partnership Entities in an amount at least equal to $8,688,750 annually (the “Minimum Gathering Pipeline Revenue Commitment”); (3) on the ▇▇▇▇▇ Cross Pipelines an amount of Crude Oil and Refined Product that will, in the aggregate, produce revenue to the Partnership Entities in an amount at least equal to $730,000 annually (the “Minimum ▇▇▇▇▇ Cross Pipeline Revenue Commitment”); and (4) on the Roswell Products Pipeline an amount of Refined Product in the aggregate that will produce revenue to the Partnership Entities in an amount at least equal to $35,000 per Contract Quarter (the “Minimum Roswell Pipeline Revenue Commitment”, together with the Minimum Trunk Pipeline Revenue Commitment, the Minimum Gathering Pipeline Revenue Commitment and the Minimum ▇▇▇▇▇ Cross Pipeline Revenue Commitment, collectively, the “Minimum Pipeline Revenue Commitment”). Notwithstanding the foregoing, in the event that the Effective Time is any date other than the first day of a Contract Year or Contract Quarter, then the Minimum Trunk Pipeline Revenue Commitment, Minimum Gathering Pipeline Revenue Commitment and Minimum ▇▇▇▇▇ Cross Pipeline Revenue Commitment for the initial Contract Year shall each be prorated based upon the number of days actually in such contract year and the initial Contract Year, and the Minimum Roswell Pipeline Revenue Commitment for the initial Contract Quarter shall be prorated based upon the number of days actually in such calendar quarter and the initial Contract Quarter.

     (ii) The Minimum Pipeline Revenue Commitment shall be adjusted on July 1 of each Contract Year commencing on July 1, 2008, by an amount equal to the percentage increase, if any, between the two (2) preceding calendar years, in the Producer Price Index for Finished Goods, seasonally adjusted, as published by the Department of Labor (“PPI”); provided, however, that the Minimum Pipeline Revenue Commitment will not decrease as a result of any decrease in the PPI. If that index is no longer published, the ▇▇▇▇▇ Entities and the Partnership Entities 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 Minimum Pipeline Revenue Commitments. If the ▇▇▇▇▇ Entities and the Partnership Entities are unable to agree, a new index will be determined by binding arbitration in accordance with Section 11(e) of this Agreement and the same method of adjustment for increases in the new index shall be used to calculate increases in the Minimum Pipeline Revenue Commitment.

     (iii) If the ▇▇▇▇▇ Entities are unable for a period in excess of thirty (30) consecutive days to transport on the Crude Oil Trunk Pipelines, the Crude Oil Gathering Pipelines, the ▇▇▇▇▇ Cross Pipelines or the Roswell Product Pipeline the respective volumes of Crude Oil and Refined Product required to meet the Minimum Pipeline Revenue Commitment as a result of the Partnership Entities’ operational difficulties, prorationing, or, (1) with respect to the Crude Oil Trunk Pipelines, the inability to provide 79,000 bpd capacity (the “Trunk Pipeline Minimum Capacity”); (2) with respect to the Crude Oil Gathering Pipelines (including storage in the Artesia Crude Oil Pipeline Tankage and Lovington Crude Oil Pipeline Tankage, but excluding storage in the Refinery Tankage), the inability to provide: (A) from the Effective Date until the fifth anniversary of the Effective Date: 50,000 bpd; (B) from the fifth anniversary of the Effective Date until the tenth anniversary of the Effective Date: 47,500 bpd; and (C) from the tenth anniversary of the Effective Date until the expiration of the Term: 45,000 bpd (collectively, the “Gathering Pipeline Minimum Capacity”); (3) with respect to the ▇▇▇▇▇ Cross Pipelines, the inability to provide 8,000 bpd capacity (the “▇▇▇▇▇ Cross Minimum Capacity”); or (4) with respect to the Roswell Products Pipeline, the inability to provide 36,000 bpq capacity (the “Roswell Pipeline Minimum Capacity”), then upon written notice by the ▇▇▇▇▇ Entities to the Partnership Entities, the Minimum Pipeline Revenue Commitment, as affected, will be reduced for such period of time by an amount equal to: (A) the volume of Crude Oil or Refined Product that the ▇▇▇▇▇ Entities are unable to transport on the Crude Oil Trunk Pipelines, the Crude Oil Gathering Pipelines, the ▇▇▇▇▇ Cross Pipelines or the Roswell Product Pipeline, as applicable, as a result of the Partnership Entities’ operational difficulties, prorationing or inability to provide the Trunk Pipeline Minimum Capacity, the Gathering Pipeline Minimum Capacity, the ▇▇▇▇▇ Cross Minimum Capacity or the Roswell Pipeline Minimum Capacity, as applicable, multiplied by (B) the applicable tariffs.

     (b) Tariffs and Tankage Fees.

     (i) The tariff rates applicable to (A) service on the Crude Oil Trunk Pipelines shall be as set forth in Exhibit A attached hereto and made a part hereof for all purposes; (B) service on the Crude Oil Gathering Pipelines shall be as set forth in Exhibit B attached hereto and made a part hereof for all purposes; (C) service on the ▇▇▇▇▇ Cross Pipelines shall be as set forth in Exhibit C attached hereto and made a part hereof for all purposes; and (D) service on Roswell Product Pipeline shall be as set forth in Exhibit D attached hereto and made a part hereof for all purposes. The rules and regulations governing service on the Pipeline Assets shall be as set forth in the applicable rules and regulations tariffs with respect to such service. The tariff rates shall be adjusted on July 1 of each Contract Year commencing on July 1, 2008, by an amount equal to the

percentage change, if any, between the two (2) immediately preceding calendar years, in the FERC Oil Pipeline Index. If that index is no longer published, the ▇▇▇▇▇ Entities and the Partnership Entities shall negotiate in good faith to agree on a new index that gives comparable protection against inflation or deflation and the same method of adjustment for increases in the new index shall be used to calculate increases in the tariff rates. If the ▇▇▇▇▇ Entities and the Partnership Entities are unable to agree, a new index will be determined by binding arbitration in accordance with Section 11(e) of this Agreement and the same method of adjustment for increases in the new index shall be used to calculate increases in the tariff rates. Notwithstanding that the Minimum Pipeline Revenue Commitment will be determined on a Contract Year basis, the applicable initial fees, tariff rates and other charges provided for in this Agreement will become effective as of the Effective Time. The Partnership Entities shall have the right to change the tariff rates applicable to the Crude Oil Trunk Pipelines, the Crude Oil Gathering Pipelines, the ▇▇▇▇▇ Cross Pipelines and the Roswell Product Pipeline in the event that the Partnership Entities incur increased expenses (or lower revenues) or capital costs, as a direct result of a change in the quality and/or consistency of the Crude Oil or Refined Product, as applicable, and to the extent thereof.

     (ii) In the event that Crude Oil throughput at the Navajo Refinery exceeds 110,000 bpd or if Crude Oil viscosity exceeds 50 SSU on greater than 10,000 bpd of such Crude Oil throughput, and the Partnership Entities incur increased expenses (or lower revenues) or capital costs, as a direct result thereof, the Parties will renegotiate the tariff rates in good faith in order to compensate the Partnership Entities on account of such incremental expenses (or lower revenues) or capital costs, which capital costs shall also include a reasonable rate of return. If the ▇▇▇▇▇ Entities and the Partnership Entities are unable to agree upon renegotiated tariff rates, the renegotiated tariff rates will be determined by binding arbitration in accordance with Section 11(e) of this Agreement.

     (c) Tankage Revenue Commitment. During the Term of this Agreement, upon the Effective Time, the ▇▇▇▇▇ Entities shall pay the Partnership Entities throughput fees associated with the Refinery Tankage in the amount of $184,000 per month (the “Tankage Revenue Commitment”) in exchange for the Partnership Entities providing to the ▇▇▇▇▇ Entities 613,333 barrels per month of crude oil storage capacity at the Refinery Tankage. The amount of the Tankage Revenue Commitment shall be adjusted upward on July 1 of each Contract Year commencing on July 1, 2008, by an amount equal to the percentage change, if any, between the two (2) immediately preceding calendar years, in the FERC Oil Pipeline Index. If that index is no longer published, the ▇▇▇▇▇ Entities and the Partnership Entities 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 Tankage Revenue Commitment. If the ▇▇▇▇▇ Entities and the Partnership Entities are unable to agree, a new index will be determined by binding arbitration in accordance with Section 11(e) of this Agreement and the same method of adjustment for increases in the new index shall be used to calculate increases in the Tankage Revenue Commitment. Notwithstanding that the Tankage Revenue Commitment will be determined on a Contract Year basis, the applicable fees, tariff rates and other charges provided for in this Agreement will become effective as of the Effective Time.

     (d) Roswell Terminal Operating Expenses and Payment.

If that index is no longer published, the ▇▇▇▇▇ Entities and the Partnership Entities 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 Roswell Terminal Payment. If the ▇▇▇▇▇ Entities and the Partnership Entities are unable to agree, a new index will be determined by binding arbitration in accordance with Section 11(e) of this Agreement and the same method of adjustment for increases in the new index shall be used to calculate increases in the Roswell Terminal Payment. The Partnership Entities shall exercise the same level of care in the operation of the Roswell Terminal as they exercise in the operation of their own terminals and pipeline assets.

     (e) Volumetric Gains and Losses. The ▇▇▇▇▇ Entities shall, during the Term, (i) absorb all volumetric gains in the Crude Oil Trunk Pipelines and Crude Oil Gathering Pipelines, and (ii) be responsible for all volumetric losses in the Crude Oil Trunk Pipelines and the Crude Oil Gathering Pipelines up to a maximum of 0.5%.

To the extent that the ▇▇▇▇▇ Entities are entitled to an exception under Section 3 of this Agreement to their obligations under Section 2(a) of this Agreement, the corresponding obligations of the Partnership Entities under this Section 2(f) will be proportionately reduced.

     (g) Drag Reducing Agents and Additives. If the Partnership Entities determine that adding drag reducing agents (“DRA”) and additives to the Crude Oil and Refined Products is reasonably required to move Crude Oil and Refined Product in the quantities necessary to meet the ▇▇▇▇▇ Entities’ schedule or as may be otherwise be required to safely move such quantities of Crude Oil and Refined Product, the Partnership Entities shall provide the ▇▇▇▇▇ Entities with an analysis of the proposed cost and benefits thereof. In the event that the ▇▇▇▇▇ Entities agree to use such additives as proposed by the Partnership Entities, the ▇▇▇▇▇ Entities shall reimburse the Partnership Entities for the costs of adding any additive, including DRA and/or other additives to the Crude Oil and Refined Product. All fuel additives, anti-icers and DRA (collectively, “Additives”) added to the Crude Oil and Refined Product pursuant to this Section 2(g) will be provided by the ▇▇▇▇▇ Entities at no cost to the Partnership Entities or, if the Partnership Entities provide Additives, then the ▇▇▇▇▇ Entities agree to reimburse the Partnership Entities for the costs of the Additives.

     (h) Reimbursement for Initial Tank Inspections. The ▇▇▇▇▇ Entities will, during the period that commences on the Effective Time and ends five (5) years thereafter (the “Initial Tank Inspection Period”), reimburse the Partnership Entities for the actual costs incurred by the Partnership Entities in performing the first regularly scheduled API 653 inspection conducted after the Effective Time of the tanks included within the Tankage Assets (the “Initial Tank Inspections”), and any repairs or tests or consequential remediation that may be required to be made to such Tankage Assets as a result of any discovery made during the Initial Tank Inspections; provided, however, that (i) the ▇▇▇▇▇ Entities are not obligated to reimburse the Partnership Entities for any costs associated with or arising from any inspection of Relocated Tank 437 or Replacement Tank 439, and (ii) upon expiration of the Initial Tank Inspection Period, all of the obligations of the ▇▇▇▇▇ Entities pursuant to this Section 5(h) shall terminate, except that the Initial Tank Inspection Period shall be extended if, and only to the extent that (a) inaccessibility of the Tankage Assets during the Initial Tank Inspection Period caused the delay of an Initial Tank Inspection originally scheduled to be performed during the Initial Tank Inspection Period, and (b) the ▇▇▇▇▇ Entities received notice from the Partnership Entities regarding such delay at the time it occurred.

     (i) Taxes. The ▇▇▇▇▇ Entities will pay all taxes, import duties, license fees and other charges by any Governmental Authority levied on or with respect to the Crude Oil and Refined Product delivered by the ▇▇▇▇▇ Entities for transportation by the Partnership Entities in the Crude Oil Trunk Pipelines including, but not limited to, any New Mexico gross receipts and compensating (use) taxes. The ▇▇▇▇▇ Entities will reimburse the Partnership Entities for

the New Mexico gross receipts tax, but not income tax, levied on or with respect to the transportation services provided by the Partnership Entities to the ▇▇▇▇▇ Entities under this Agreement. Should any Party be required to pay or collect any taxes, duties, charges and or assessments pursuant to any federal, state, county or municipal law or authority now in effect or hereafter to become effective which are payable by the any other Party pursuant to this Section 2(i) the proper Party shall promptly reimburse the other Party therefor.

     (j) Timing of Payments. The ▇▇▇▇▇ Entities will make payments to the Partnership Entities by electronic payment with immediately available funds on a monthly basis during the Term with respect to services rendered by the Partnership Entities under this Agreement in the prior month. Payments not received by the Partnership Entities on or prior to the applicable payment date will accrue interest at the Prime Rate from the applicable payment date until paid.

     (k) Marketing of Transportation and Storage Services. The Partnership may market transportation and storage services to third parties on the Crude Oil Trunk Pipelines or the Crude Oil Gathering Pipelines, provided that (i) the Partnership provides the ▇▇▇▇▇ Entities with prior written notice describing the purported transportation and/or storage services to the extent permitted by law; and (ii) the ▇▇▇▇▇ Entities remain satisfied that such transportation and storage services marketed by the Partnership has not negatively affected the ▇▇▇▇▇ Entities’ ability to utilize the Drop-Down Assets in any material respect and the quality and quantity of the Crude Oil has not been materially degraded or otherwise impaired.

     (l) Change in Pipeline Direction; Product Service or Origination and Destination. Without Holly’s prior written consent, which shall not be unreasonably withheld, the Partnership Entities shall not (i) reverse the direction of any of the Pipeline Assets; (ii) change, alter or modify the product service of any of the Pipeline Assets; or (iii) change, alter or modify the origination or destination of any of the Pipeline Assets; provided, however, that the Partnership Entities may take any necessary emergency action to prevent or remedy a release of Crude Oil or Refined Product, as applicable, from any of the Pipeline Assets without obtaining the consent required by this Section 2(l). The ▇▇▇▇▇ Entities shall have the right to reverse the direction of any of the Pipeline Assets if the ▇▇▇▇▇ Entities agree to (i) reimburse the Partnership Entities for the additional costs and expenses incurred by the Partnership Entities as a result of such change in direction (both to reverse and re-reverse); (ii) reimburse the Partnership Entities for all costs arising out of the Partnership Entities’ inability to perform under any transportation service contract due to the reversal of the direction of the Pipeline Assets; and (iii) pay the flow reversal rates as set forth on Exhibit E. The tariff rates applicable to any such flow reversal shall be as set forth on Exhibit E and shall be adjusted each year as provided in Section 2(a)(ii).

     (m) Notification of Utilization. Upon request by the Partnership Entities, ▇▇▇▇▇ will provide to the Partnership Entities written notification of Holly’s reasonable good faith estimate of its anticipated future utilization of any of the Drop-Down Assets.

     (n) Scheduling and Accepting Deliveries. The Partnership Entities will use their reasonable commercial efforts to schedule movement and accept deliveries of Crude Oil and Refined Product in a manner that is consistent with the historical dealings between the Parties, as such dealings may change from time to time.

     (o) Increases in Pipeline Tariff Rates and Tankage Fees. If new laws or regulations are enacted that require the Partnership Entities to make capital expenditures with respect to the Drop-Down Assets, the Partnership Entities may amend the tariff rates in order to recover the Partnership Entities’ cost of complying with these laws or regulations (including a reasonable return). The ▇▇▇▇▇ Entities and the Partnership Entities shall use their reasonable commercial efforts to comply with these laws and regulations, and shall negotiate in good faith to mitigate the impact of these laws and regulations and to determine the amount of the new tariff rates. If the ▇▇▇▇▇ Entities and the Partnership Entities are unable to agree on the amount of the new tariff rates that the Partnership Entities will charge, such tariff rates will be determined by binding arbitration in accordance with Section 11(e) of this Agreement.

     Section 3. 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 3 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. The ▇▇▇▇▇ Entities 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 the Partnership Entities or the ▇▇▇▇▇ Entities 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 the Partnership Entities or the ▇▇▇▇▇ Entities. Nothing in this Section 3(a) shall alter the liability of the Partnership Entities as set forth in the applicable rules and regulations tariffs for the Pipeline Assets.

     Section 4. Agreement to Remain Shipper

     With respect to any Refined Product that is produced at a Refinery and transported in the Roswell Products Pipeline or any Crude Oil that is acquired by the ▇▇▇▇▇ Entities and transported on the Crude Oil Trunk Pipelines and stored in the Artesia Crude Oil Pipeline Tankage or Lovington Crude Oil Pipeline Tankage, the ▇▇▇▇▇ Entities agree that they will continue their historical commercial practice of owning such Crude Oil or Refined Product, as applicable, from such point as (i) the Refined Product leaves the Refinery until at least such point as it will not be further transported in the Roswell Products Pipeline and to continue acting in the capacity of the shipper of such Refined Product for their own account at all times that such Refined Product is in the Roswell Products Pipeline; and (ii) the Crude Oil is received into the Crude Oil Gathering Pipelines by the Partnership Entities until such time that it is delivered to the Artesia Refinery or delivered to the Lovington Crude Oil Pipeline Tankage at the Lovington Refinery.

     Section 7. Right to Enter into a New Agreement

     (a) In the event that the ▇▇▇▇▇ Entities provide prior written notice to the Partnership Entities of the desire of the ▇▇▇▇▇ Entities 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 the Partnership Entities shall have the right to negotiate to enter into one or more pipeline and tankage agreements with one or more third parties to begin after the date of termination, provided that until the end of one year following termination without renewal of this Agreement, the ▇▇▇▇▇ Entities will have the right to enter into a new pipelines and tankage agreement with the Partnership Entities on commercial terms that substantially match the terms upon which the Partnership Entities propose to enter into

an agreement with a third party for similar services with respect to all or a material portion of the Drop-Down Assets. In such circumstances, the Partnership Entities shall give the ▇▇▇▇▇ Entities forty-five (45) days prior written notice of any proposed new pipelines and tankage agreement with a third party, and such notice shall inform the ▇▇▇▇▇ Entities of the fee schedules, tariffs, duration and any other terms of the proposed third party agreement and the ▇▇▇▇▇ Entities shall have forty-five (45) days following receipt of such notice to agree to the terms specified in the notice or the ▇▇▇▇▇ Entities shall lose the rights specified by this Section 7(a) 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, the Partnership Entities shall deliver to the ▇▇▇▇▇ Entities a written notice (the “Deficiency Notice”) detailing any failure of the ▇▇▇▇▇ Entities to meet their obligations under Section 2(a)(i), Section 2(c) or Section 2(d) of this Agreement, provided that the ▇▇▇▇▇ Entities’ obligations pursuant to the Minimum Trunk Pipeline Revenue Commitment, Minimum Gathering Pipeline Revenue Commitment, Minimum ▇▇▇▇▇ Cross Pipeline Revenue Commitment and the Minimum Roswell Pipeline Revenue Commitment shall, in each case, be assessed on a 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 the Partnership Entities believe would have been paid by the ▇▇▇▇▇ Entities to the Partnership Entities if the ▇▇▇▇▇ Entities had complied with their respective obligations pursuant to Section 2(a)(i), Section 2(c) or Section 2(d) of this Agreement, as applicable (the “Deficiency Payment”). The ▇▇▇▇▇ Entities shall pay the Deficiency Payment to the Partnership Entities 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 the ▇▇▇▇▇ Entities disagree with the Deficiency Notice, then, following the payment of the Deficiency Payment to the Partnership Entities, a senior officer of ▇▇▇▇▇ (on behalf of the ▇▇▇▇▇ Entities) and a senior officer of ▇▇▇▇▇ GP (on behalf of the Partnership Entities) 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, the ▇▇▇▇▇ Entities shall have access to the working papers of the Partnership Entities relating to the Deficiency Notice. If such differences are not resolved within thirty (30) days

following the payment of the Deficiency Payment, the ▇▇▇▇▇ Entities and the Partnership Entities shall, within forty-five (45) days following the payment of the Deficiency Payment, submit any and all matters which remain in dispute and which were properly included in the Deficiency Notice to arbitration in accordance with Section 11(e).

     (c) If it is finally determined pursuant to this Section 9 that the ▇▇▇▇▇ Entities are not required to make any or all of the Deficiency Payment (the “Refund”), the Partnership Entities shall promptly pay to the ▇▇▇▇▇ Entities the Refund, 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 volumes with respect to the Minimum Pipeline Revenue Commitment.

     (e) The Parties acknowledge and agree that the Minimum Pipeline Revenue Commitment shall not be aggregated for purposes of determining any deficiency pursuant to this Section 9.

     (f) No Party shall have a right to setoff revenue in excess of the minimum revenue commitment of the Minimum Trunk Pipeline Revenue Commitment, the Minimum Gathering Pipeline Revenue Commitment, the Minimum ▇▇▇▇▇ Cross Pipeline Revenue Commitment or the Minimum Roswell Pipeline Revenue Commitment with respect to any deficiency under the Minimum Trunk Pipeline Revenue Commitment, the Minimum Gathering Pipeline Revenue Commitment, the Minimum ▇▇▇▇▇ Cross Pipeline Revenue Commitment or the Minimum Roswell Pipeline Revenue Commitment.

     Section 10. Right of First Refusal The Parties acknowledge that the ▇▇▇▇▇ Entities shall, at any time during the twelve (12) months prior to the expiration of the Term, have a right of first refusal with respect to the Drop-Down Assets to the extent provided by the Omnibus Agreement and made applicable to the Drop-Down Assets pursuant to Section 11.4(a) of the Purchase Agreement.

     Section 11. 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 hereto and, in the case of any amendment or modification adverse to the Partnership Entities, approved by the Conflicts Committee. 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, and, in the case of any waiver by the Partnership Entities, approved by the Conflicts Committee. 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, the ▇▇▇▇▇ Entities, the Partnership Entities 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 ▇▇▇▇▇ (in the case of any assignment by the Partnership Entities) or the Conflicts Committee (in the case of any assignment by the ▇▇▇▇▇

Entities), in each case, such consent is not to be unreasonably withheld or delayed; provided, however, that (i) the Partnership Entities may make such an assignment (including a partial pro rata assignment) to an Affiliate of the Partnership Entities without Holly’s consent, (ii) the ▇▇▇▇▇ Entities may make such an assignment (including a pro rata partial assignment) to an Affiliate of the ▇▇▇▇▇ Entities without the consent of the Conflicts Committee, (iii) the ▇▇▇▇▇ Entities may make a collateral assignment of their rights and obligations hereunder and/or grant a security interest in all or a portion of the Drop-Down Assets to any bona fide third party lender or debt holder, or trustee or representative for any of them, and (iv) the Partnership Entities may make a collateral assignment of their rights hereunder and/or grant a security interest in all or a portion of the Drop-Down Assets to a bona fide third party lender or debt holder, or trustee or representative for any of them, if such third party lender, debt holder or trustee shall have executed and delivered to the ▇▇▇▇▇ Entities a non-disturbance agreement in such form as is reasonably satisfactory to the ▇▇▇▇▇ Entities and the ▇▇▇▇▇ Entities execute 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 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 Texas, 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 11(e) and the Commercial Arbitration Rules or the Federal Arbitration Act, the terms of this Section 11(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 or for 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 the ▇▇▇▇▇ Entities, the Partnership Entities or any of their Affiliates and (ii) have not less than seven (7) years experience in the energy industry. The hearing will be conducted in Dallas, Texas and commence within thirty (30) days after the selection of the third arbitrator. The ▇▇▇▇▇ Entities, the Partnership Entities 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.

     (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.
