If the Parties cannot agree on any such arrangement within a reasonable time, or any such arrangement would not be reasonably practicable, to provide the Buyer in question with materially all the benefits of such Asset or materially all the obligations of such Assumed Liability, as the case may be, then such Asset or Assumed Liability shall be excluded from the transactions contemplated under this Agreement and shall be deemed to be an Excluded Asset or an Excluded Liability, as the case may be, and, with respect to the Key Material Contracts only, the Seller and Buyer in question shall negotiate in good faith an equitable adjustment in the applicable Buyer’s portion of the Purchase Price, or resolve any disagreement in respect to such adjustment subject to the terms of Section 11.6 . For the avoidance of doubt, the covenants set forth in this Section 2.5 apply pre-Closing and post-Closing.

          2.6.3 Purchase Price Adjustments .

               2.6.3.1 The Purchase Price payable by Holly Tulsa shall be adjusted to include the value of the Hydrocarbon Inventory established in accordance with the procedures set forth in this Section 2.6.3 (the “ Hydrocarbon Inventory Value ”).

               2.6.3.2 At least five (5) days, but no more than ten (10) days prior to the Closing Date, the Seller will measure, and Holly Tulsa will provide one or more persons to witness the Seller’s measurements of, the Hydrocarbon Inventory and the Excluded Hydrocarbon Inventory as of such date . At least five (5) days prior to Closing Date, the Seller shall prepare

and deliver to Holly Tulsa a statement (the “ Estimated Hydrocarbon Inventory Statement ”) setting forth the Estimated Hydrocarbon Inventory Value established in accordance with Schedule 2.6.3.2 taking into account the foregoing measurements as of such date, together with reasonably detailed information supporting the calculated Estimated Hydrocarbon Inventory Value, and reduced or increased by significant transactions during the period between the measurement of the Hydrocarbon Inventory and the day such statement is delivered to Holly Tulsa (the “ Estimated Closing Date Hydrocarbon Inventory Value ”). The Parties intend that the Hydrocarbon Inventory target volumes by product type at the Closing Date shall be as set forth in Schedule 2.6.3.2 hereto.

               2.6.3.3 On the morning of the Closing Date, Holly Tulsa and the Seller will cause the Petroleum Inspection Company to measure, pursuant to the procedures on Schedule 2.6.3.2 , the Hydrocarbon Inventory and the Excluded Hydrocarbon Inventory as of such time (the “ Hydrocarbon Inventory Transfer Time ”). Holly Tulsa and the Seller shall each pay 50% of the costs of such measurement by the Petroleum Inspection Company. As soon as practicable on the Closing Date, and following the measurement of the Hydrocarbon Inventory and the Excluded Hydrocarbon Inventory by the Petroleum Inspection Company, the Seller will deliver to Holly Tulsa a statement setting forth a revised Estimated Hydrocarbon Inventory Value as of the Hydrocarbon Inventory Transfer Time (such revised value being referred to as the “ Closing Date Hydrocarbon Inventory Value ”), taking into account the foregoing measurements as of the Hydrocarbon Inventory Transfer Time by the Petroleum Inspection Company and such amount shall be paid as part of any Adjustment Balance in accordance with Section 2.6.4 .

               2.6.3.4 Notwithstanding the foregoing, if the Estimated Closing Date Hydrocarbon Inventory Value reflects more than 1,000,000 barrels of Hydrocarbon Inventory, then the amount payable by Holly Tulsa at Closing pursuant to Section 2.6.1.2.(1) shall be recalculated based on the assumption that there were only 1,000,000 barrels of Hydrocarbon Inventory. In recalculating such amount, the inventory shall be deemed adjusted by first excluding finished gasoline inventory, second by excluding finished diesel fuel inventory and third by excluding crude oil to the extent necessary to reduce the applicable Hydrocarbon Inventory to 1,000,000 barrels. If the Estimated Closing Date Hydrocarbon Inventory Value does reflect more than 1,000,000 barrels of Hydrocarbon Inventory, then Holly Tulsa shall pay Seller on the fifth Business Day following Closing an amount equal to the Estimated Closing Date Hydrocarbon Inventory Value (without regard to the 1,000,000 barrel limit) less the portion of the Estimated Closing Date Hydrocarbon Inventory Value that was paid to Seller on the Closing Date.

          2.6.4 Post-Closing Adjustments . The following adjustments shall be made following Closing:

               2.6.4.1 As soon as practicable, but in any event no later than sixty (60) days following the Closing Date, Holly Tulsa shall cause to be prepared and delivered to the Seller a statement (the “ Post-Closing Statement ”) setting forth the aggregate value of all

adjustments to the Purchase Price required by Section 2.6.3.1 and Section 2.7.3 not previously effected (the “ Adjustment Balance ”) (with adjustments reducing the Purchase Price to an amount less than the amount of estimated Purchase Price paid at Closing being a negative number to the extent of the deficit and adjustments increasing the Purchase Price to an amount in excess of the amount of estimated Purchase Price paid at Closing being a positive number to the extent of such surplus) together with reasonably detailed information supporting the Adjustment Balance. Upon receipt of the Post-Closing Statement, the Seller and the Seller’s independent accountants shall be permitted during the succeeding thirty (30) day period to examine the Post-Closing Statement, the supporting information provided by the Buyers and such other documents as the Seller may reasonably request in connection with its review. If, within thirty (30) days following delivery of the Post-Closing Statement, the Seller shall not have given Holly Tulsa notice of the Seller’s objection to any of the computations in the Post-Closing Statement (which notice shall contain a reasonably detailed statement of the basis of such objection), then the Post-Closing Statement will be final and binding upon the Parties. If the Seller gives notice to Holly Tulsa of the Seller’s objection, and the Seller and Holly Tulsa are unable to resolve the issues in dispute within thirty (30) days after delivery of such notice of objection, such dispute shall be finally and exclusively referred to and settled by arbitration under the Commercial Arbitration Rules of the American Arbitration Association (the “ AAA ”); provided , that the foregoing shall not prevent any Party from seeking any court order in aid of arbitration and, provided further, that only disputes between the Parties related to the Adjustment Balance shall be submitted to and determined through arbitration, and this provision shall not limit the applicability of Section 11.6 below to all other disputes arising out of or related to this Agreement. In the event of any conflict between the Commercial Arbitration Rules of the AAA and the provisions of this Section, the provisions of this Section shall govern and control. The arbitration shall be heard and determined by three (3) neutral arbitrators. Each side shall appoint an arbitrator of its choice within five (5) days of the submission of a notice of arbitration. The Party-appointed arbitrators shall in turn appoint a presiding arbitrator of the tribunal within five (5) days following the appointment of both Party-appointed arbitrators. If the Party-appointed arbitrators cannot reach agreement on a presiding arbitrator of the tribunal and/or one Party fails or refuses to appoint its Party-appointed arbitrator within the prescribed period, the appointing authority for the presiding arbitrator and/or such Party-appointed arbitrator shall be the AAA, which, in each case, shall appoint an independent arbitrator who does not have any financial interest in the dispute, controversy or claim or bear any relationship to either Party. Unless otherwise expressly agreed in writing by the parties to the arbitration proceedings: (i) the arbitration proceedings shall be held in Dallas, Texas; (ii) the arbitrators shall be and remain at all times wholly independent and impartial; (iii) the arbitration proceedings shall be conducted under the Commercial Arbitration Rules of the AAA, as amended from time to time; (iv) any procedural issues not determined under the arbitration rules selected pursuant hereto shall be determined by the arbitration act and any other Laws of the State of Utah, other than those laws which would refer the matter to another jurisdiction; (v) all decisions and awards by the arbitration tribunal with respect to the determination of the Adjustment Balance shall be made by majority vote, shall be reduced to writing, shall state the reasoning on which the award is based, shall be final and binding without the right of appeal and shall constitute the final and exclusive determination of the Adjustment Balance for purposes of the Post-Closing Statement; (vi) the Adjustment Balance determined by the arbitrators shall be promptly paid free of any deduction or offset; and (vii) any costs or fees incident to enforcing the Adjustment Balance determined by the arbitrators shall, to the

maximum extent permitted by Law, be charged against the Party resisting such enforcement. The fees of the arbitrators shall be borne by Holly Tulsa, on the one hand, and the Seller, on the other hand, in the same proportion that the dollar amount of disputed items lost by Holly Tulsa, on the one hand, or the Seller, on the other hand, bears to the total dollar amount in dispute that is resolved by the arbitrators, and the arbitrators shall set forth apportionment of such fees (according to the foregoing) as part of their decision. Each of the respective Parties shall bear all other fees, costs and expenses of the arbitration proceedings (including reasonable attorneys’ fees and costs) incurred by such Party. The arbitration shall proceed in the absence of a Party who, after due notice, fails to answer or appear; determination of the Adjustment Balance shall not be made solely on the default of a Party, but the arbitrator(s) shall require the Party that is present to submit such evidence as the arbitrators may determine is reasonably required to determine the Adjustment Balance.

               2.6.4.2 If the Adjustment Balance, as finally determined pursuant to Section 2.6.4.1 , is less than zero, then the Seller shall pay to Holly Tulsa an amount equal to such deficit by wire transfer of immediately available funds to such account or accounts of Holly Tulsa, as may be designated by Holly Tulsa. If the Adjustment Balance is greater than zero, Holly Tulsa shall pay to the Seller an amount equal to the surplus by wire transfer of immediately available funds to such account or accounts of the Seller, as may be designated by the Seller. Such amounts shall be paid by the applicable Party to the other Party within two (2) Business Days of the final determination of the Adjustment Balance pursuant to Section 2.6.4.1 , which amount of the payment shall bear interest from and including the Closing Date to, but excluding, the date of payment at a rate per annum equal to 4%. Such interest shall be payable at the same time as the payments to which it relates and shall be calculated on the basis of a year of three hundred sixty-five (365) days and the actual number of days for which it is due.

               2.6.4.3 Each Party agrees that, following the Closing, it shall not knowingly take any actions with respect to the accounting books, records, policies and procedures of the Business that would obstruct or prevent the preparation of the Post-Closing Statement as provided in this subsection. The Seller shall cooperate in the preparation of the Post-Closing Statement, including providing customary certifications to each Buyer, or, if requested, to each Buyer’s independent accountants or the accounting firm selected by mutual agreement of the Parties pursuant to this Section. The Buyers and the Seller shall each bear its own expenses incurred in connection with the preparation and review of the Post-Closing Statement.

In addition, the Seller will reasonably cooperate with the applicable Buyer’s efforts to: obtain surveys, title commitments and vesting and exception documents identified therein or reasonably required in connection with a commercially reasonable review and evaluation of the same; cause the Title Company to remove coverage exceptions from the title commitments with respect to the Owned Real Property that are inappropriately listed as exceptions or the substance of which, if such exceptions continue to be applicable to the Owned Real Property, will materially detract from the value of the Owned Real Property as currently used or materially interfere with the applicable Buyer’s use and operation of the Owned Real Property as currently used in connection with the Business. Notwithstanding the foregoing, such cooperation shall not require the Seller to expend or pay any monies or otherwise assume or become subject to any Liabilities that are not otherwise contemplated hereby; provided, however , that Seller shall remove or cause to be removed (or, in the case of involuntary liens, such as mechanics or materialman liens, to bond around to the satisfaction of the Title Company and the Buyers (which consent by the Buyers shall not be unreasonably withheld)) any lien or other monetary encumbrance on the Owned Real Property securing the payment of an obligation arising by, through or under Seller.

Without limiting the generality of the preceding sentence, each of the Buyers agrees to provide the Seller and its Affiliates reasonable access to and the right to make copies of the Books and Records delivered to such Buyer hereunder after the Closing Date for the purposes of assisting the Seller and its Affiliates (a) in complying with the Seller’s obligations under this Agreement (including to comply with any indemnity obligations), (b) in preparing and delivering any accounting statements provided for under this Agreement and adjusting, prorating and settling the charges and credits provided for in this Agreement, (c) in owning or operating the Excluded Assets or Excluded Liabilities, (d) in preparing Tax returns, (e) in responding to or disputing any Tax audit, (f) in asserting, defending or otherwise dealing with any claim or dispute, known or unknown, under this Agreement or with respect to Excluded Assets or Excluded Liabilities or (g) in asserting, defending or otherwise dealing with any Third Party Claim or dispute by or against the Seller or its Affiliates relating to the Business.

All goodwill arising from such use shall inure to the Seller. The nature and quality of all goods and services rendered by either Buyer in connection with the retained name shall be advertised, offered and provided in a manner consistent with the quality control standards previously used by the Seller, and each Buyer will use the Retained Name in compliance with all applicable laws and regulations.

On the Effective Date, the Seller shall provide to each Buyer a list of all active employees of the Seller or an Affiliate of the Seller, other than those identified in a separate list that Seller and Buyers have agreed to on the Effective Date (the “ Excluded Employee List ”), who are employed in the operation of the Business and located at the Facilities (the “ Current Employees ”), including employees who are receiving short-term disability or are on family and medical leave, military leave, or other extended leave (the “ Current Employees List ”). The Excluded Employee List is a list of the employees, by name and job title, which the Buyers and the Seller agree will not be included on the Current Employees List and are employees the Seller or an Affiliate of the Seller may retain and transfer to other jobs with the Seller or an Affiliate of the Seller outside of the Facilities and with no continuing access to the Facilities. The Seller shall also provide on the Effective Date a list (the “ Leased Personnel List ”) of staffing companies or agencies and independent contractors (the “ Leased Personnel ”) that are not Affiliates of the Seller and that have a written agreement with the Seller or an Affiliate of the Seller to provide individual workers to perform work at the Facilities or to support the operations of the Business as of the Effective Date or a date no more than three business days prior to the Effective Date. The Current Employees List shall include each Current Employee’s (a) name, (b) current job title or position and duty station, (c) service dates recognized by the Seller, (d) current base salary or the base hourly rate, and (e) status (e.g., full-time, part-time, exempt, non-exempt, on leave), and if on leave, the type of leave (e.g., vacation, short-term disability or FMLA leave, military leave or other leave) and, if known, the expected date of the employee’s return from such leave. The Leased Personnel List shall include a brief summary of the classification or type of services and fee arrangement for each listed company, agency or independent contractor. The Seller or its Affiliate, as applicable, will not transfer any Current Employee from the Facility between the Effective Date and the Closing Date except as agreed by the Buyers. The Seller or its Affiliate, as applicable, shall not terminate any Current Employees stationed at the Facilities other than for cause, as reasonably determined by the Seller

or its Affiliate, during the 30-day period preceding the Closing Date without the written approval of the Buyers, which such approval will not be unreasonably withheld. The Seller shall provide the Buyers with an updated Current Employees List not later than two Business Days prior to the Closing Date. Within three Business Days after the Effective Date, the Seller shall deliver to the Buyers electronic files (in a format compatible with the Buyers’ information systems) that include all of the foregoing information together with, to the extent permitted by applicable Laws, such other information as Buyer and Seller agree in writing.

          6.3.2 Employment Offers . After the Effective Date, and with Seller or its Affiliate’s consent (which shall not be unreasonably withheld), each Buyer shall be permitted to interview Seller’s managers during regular business hours (in person or by telephone). At least 21 days prior to the Closing Date (but in no event sooner than November 1, 2009), each of the Buyers shall make offers of employment, effective as of the Closing Date and contingent upon the occurrence of the Closing, to those Current Employees to whom such Buyer has elected to extend an offer; provided , however , that for purposes of clarity, it is hereby noted that offers of employment shall not be made to the employees listed on the Excluded Employee List. The offers of employment by the Buyers shall be made to not less than the minimum number of Current Employees (excluding Current Employees who are part-time employees as defined in the WARN Act) set forth on Schedule 6.3.2 (the “ Minimum Offer Number ”), or such greater number as Buyers in their sole discretion elect. The Seller represents to Buyers that the Minimum Offer Number constitutes more than 67% of the employees of the Seller and its Affiliates who must be taken into account in determining whether the transactions contemplated by this Agreement will give rise to or constitute a “mass layoff” or “plant closing” by the Seller and its Affiliates for purposes of the WARN Act. The Buyers shall cause all such offers of employment by the Buyers to the Minimum Offer Number of Current Employees to be on terms and conditions of employment such that if the representation by the Seller in the immediately preceding sentence regarding the Minimum Offer Number is correct, no Current Employees shall, as a result of ceasing to be employed by the Seller or its Affiliates immediately prior to, on or after the Closing Date or any action contemplated by this Agreement taken by Buyers, be deemed to have been terminated by the Seller or its Affiliates in a “mass layoff” or “plant closing” as defined in the WARN Act for purposes of imposing any obligation or Liability on the Seller or any of its Affiliates under the WARN Act with respect to its Current Employees. The Current Employees to whom either Buyer extends an offer are referred to as the “ Selected Employees .” Each such offer shall provide that, during the portion of the one-year period beginning on the Closing Date that the employee continues to be employed by the Buyer or an Affiliate of the Buyer, such Buyer shall provide the employee with employee benefits on a basis substantially similar to those provided to similarly situated new employees of the Buyer and its Affiliates, but with credit for welfare plan out-of-pocket payments and prior service to the extent provided in Sections 6.3.6, 6.3.7, 6.3.8 and 6.3.9 . The Seller shall not take any action that is intended to discourage or interfere with either Buyer’s attempt to hire the Selected Employees. Each of the Buyers will provide the Seller with a list at least two (2) Business Days before the Closing Date, which shall contain as of that date the names of the Selected Employees, a certification that the offer to each Selected Employee satisfied the requirements of this Section 6.3 , and whether the Selected Employee accepted the offer. Any Selected Employee who accepts a Buyer’s offer of employment and who on the Closing Date is (i) actively at work or (ii) on a holiday, scheduled day off pursuant to his or her regular schedule, or a vacation

authorized prior to the Closing Date by the Seller or an Affiliate of the Seller and returns to work as scheduled, shall become or be deemed employed by the applicable Buyer as of the Closing Date (the “ Employment Date ”). Any Selected Employee who accepts a Buyer’s offer of employment and who on the Closing Date is on a leave of absence or short-term disability leave consistent with the Seller’s or an Affiliate of Seller’s established policies and practices that was authorized by the Seller or an Affiliate of the Seller prior to the Closing Date, including any FMLA leave or military leave, and returns to work at the end of such authorized leave, shall become employed by the applicable Buyer as of the date of his or her return to work with such date being deemed the Employment Date for such employee; provided that any such Selected Employee shall be required to comply with the applicable Buyer’s return-to-work policies and practices, including, but not limited to, any requirement that the employee establish he or she is able to perform the essential functions of the position, with or without reasonable accommodation. Each Selected Employee who becomes employed by a Buyer shall be referred to herein as a “ Continuing Employee ” of that Buyer.

          6.3.3 Retained Employees; Severance Liabilities . The Current Employees who are on long-term leave on the Closing Date, the Current Employees who are not Selected Employees and those Selected Employees who are offered and do not accept employment with either Buyer or do not become employed by either Buyer shall be referred to collectively as the “ Retained Employees .” The Seller or its Affiliates may retain the services of any Retained Employee except for any Retained Employees who do not accept offers of employment from a Buyer or terminate the employment of any Retained Employee on or following the Closing Date. The Seller shall retain Liability and be responsible for and indemnify and hold harmless the Buyers and their respective Affiliates against all salaries or wages and benefits and all other claims, costs, expenses and Liabilities relating to or arising out of the employment or termination of the employment of the Retained Employees by the Seller or its Affiliates; provided , however , that (a) each of the Buyers shall assume Liability and be responsible for and indemnify and hold harmless the Seller and its Affiliates against all Liabilities arising out of any selection or pre-employment process applied by that Buyer to the Current Employees and (b) Holly Tulsa shall reimburse the Seller and its Affiliates for all “Severance Costs” as defined on Schedule 6.3.3 in excess of the threshold amount set forth in Section C on Schedule 6.3.3 (which excess shall be paid by Holly Tulsa to the Seller promptly after the Seller or its Affiliates pay such costs).

          6.3.4 Continuing Employees . All Continuing Employees shall cease to be employees of Seller and its Affiliates as of the time immediately preceding their Employment Date and shall become employees of Holly Tulsa or HEP Tulsa, as applicable, as of their Employment Date and, at such time, the applicable Buyer shall, subject to Section 6.3.13 , assume and be responsible for and indemnify and hold harmless the Seller and its Affiliates against payment of all salaries or wages and benefits and all other claims, costs, expenses and Liabilities relating to the Continuing Employees’ employment with or termination of employment with that Buyer and its Affiliates that arise on or after their Employment Date. Subject to Section 6.3.2 and Section 6.3.3 , the Seller shall retain Liability and be responsible for and indemnify and hold harmless the Buyers against all salaries or wages and benefits and all other claims, costs, expenses and Liabilities related to or arising out of Seller’s employment decisions or practices relating to its employment or termination of the Continuing Employees prior to their Employment Date. Subject to Section 6.3.13 , nothing in this Agreement shall limit

the right of a Buyer that initially employs a Continuing Employee to later terminate the employment of that Continuing Employee following his or her Employment Date, with or without cause; provided , however , that the Buyers and their Affiliates shall not terminate the employment of a Continuing Employee or take any other action if such termination or action gives rise to any obligation or Liability on behalf of the Seller or any of its Affiliates under the WARN Act (including penalties under the WARN Act and any pay made in lieu of WARN Act-required notice). For purposes of clarity, it is agreed that any termination of employment by the Seller or its Affiliates of any Current Employee or Retained Employee shall not relieve the Buyers and their Affiliates of their obligations not to terminate the employment of a Continuing Employee or take any other action with respect to a Continuing Employee, or reduce the Buyers’ Liability with respect thereto, if such termination or action by the Buyers will give rise to any obligation or Liability under the WARN Act on behalf of the Seller or any of its Affiliates. The Seller waives any claims against the Buyers and the Continuing Employees arising under any employment, confidentiality or non-disclosure agreement, or non-competition agreement between any such Continuing Employee and the Seller to the extent that any breach of such Continuing Employee’s employment, confidentiality or non-competition agreement is with respect to the information or matters relating to the Business or the Assets required for such Continuing Employee’s employment with either Buyer. The Seller shall not solicit for employment or the provision of other services, for a period of two (2) years following the Closing Date, any Continuing Employee designated by a Buyer in writing to the Seller within ten (10) days following the Closing Date; provided , however , that the foregoing restriction shall not apply to any general solicitations not directed to any such individual.

          6.3.5 Buyer Plans . Each Continuing Employee shall cease active participation in all Seller Plans as of 11:59 p.m. on the date preceding his or her Employment Date; provided , however , that if a Continuing Employee was covered immediately prior to his or her Employment Date under the Seller Plan that provides group medical benefits, and if such Employment Date occurs on other than the first day of a calendar month, then the Continuing Employee shall continue to receive coverage under such Seller Plan until 11:59 p.m. on the last day of the calendar month in which such Employment Date occurs. Each Buyer and its respective Affiliates shall take such action as may be reasonably necessary so that, as of his or her Employment Date, Continuing Employees who are eligible to so participate under the terms of the applicable Buyer’s benefit plans that are required to be made available to Continuing Employees pursuant to Section 6.3.2 (each a “ Buyer Plan ”), are offered an opportunity to participate in such Buyer Plans. Subject to Section 6.3.3 , the Seller shall retain and the Buyers shall not have any responsibilities, liabilities or obligations, whether to Current Employees, former employees, their beneficiaries or to any other Person, under or with respect to any Seller Plan, including any severance plan or plan providing post-employment welfare benefits. Nothing contained herein, whether express or implied, shall limit the right of any Buyer or any of its Affiliates to amend, terminate, or otherwise modify any Buyer Plan following the Closing Date. The Seller shall not have any responsibility, liability or obligation, whether to Continuing Employees, their beneficiaries or to any other Person, with respect to any Buyer Plan.

          6.3.6 Savings Plan . Effective as of the Closing Date, each of the Buyers shall take all action reasonably necessary and appropriate to include the Continuing Employees hired by it in the U.S. tax-qualified defined contribution savings and investment 401(k) plan

established or to be established by that Buyer (the “ Buyer Savings Plan ”), subject to the eligibility requirements of the applicable Buyer Savings Plan. Each Buyer shall grant to the Continuing Employees hired by the Buyer service credit for service recognized by the Seller or its Affiliates for eligibility to participate and vest in the Buyer Savings Plan.

          6.3.7 Welfare and Other Non-Pension Fringe Benefits . Effective as of the Closing Date, each of the Buyers shall take all action reasonably necessary and appropriate to include the Continuing Employees hired by such Buyer in the Buyer’s existing, broad-based group health, life and disability plans as well as other employee welfare and fringe benefit plans and programs to the extent the Continuing Employees meet eligibility requirements for such plans, including any requirements for verification of dependent eligibility and verification of prior creditable coverage, that are substantially the same as the requirements applied to similarly situated new employees of the applicable Buyer and its Affiliates, without any credit for prior years of service with Seller under Section 6.3.9 or otherwise. Each Buyer shall provide coverage and benefits under the Buyers’ broad-based welfare and other non-pension fringe benefit plans to each Continuing Employee hired by the Buyer beginning on such Continuing Employee’s Buyer Welfare Plan Start Date. The Seller or its Affiliates shall have no responsibility for providing benefits under any welfare benefit plan of Seller or its Affiliates to a Continuing Employee from and after such Continuing Employee’s Seller Welfare Plan End Date; provided , however , that the Seller or its Affiliates shall remain liable for any claims of each Continuing Employee incurred prior to such Continuing Employee’s Seller Welfare Plan End Date under the Seller’s or its Affiliates’ medical and life insurance, flexible spending, dependent care and all other welfare programs in accordance with the terms of such plans as in effect prior to the Continuing Employee’s Seller Welfare Plan End Date, and the Seller or its Affiliates shall continue to fully process all claims incurred by each Continuing Employee (and to the extent applicable, each Continuing Employee’s spouse, dependents, or beneficiaries) prior to such Continuing Employee’s Seller Welfare Plan End Date for all benefits under the Seller’s or its Affiliates’ medical and life insurance, flexible spending, dependent care and all other welfare programs in which the Continuing Employee was eligible to participate at any time prior to the Continuing Employee’s Seller Welfare Plan End Date. For the purposes of this Section 6.3.7 , a claim will be deemed incurred, in the case of hospital, medical or dental benefits, when the services that are the subject of the charge are performed and, in the case of other benefits (such as disability or life insurance), when an event has occurred that entitles the employee to the benefit. The Buyer Plans will credit each Continuing Employee hired by the sponsoring Buyer for all participant payments made by such Continuing Employee for health care expenses under the Seller Plans for purposes of deductibles and maximum out-of-pocket limits during the applicable Buyers’ plan year in which the Continuing Employee’s Buyer Welfare Plan Start Date occurs provided the Seller, the Seller’s applicable carrier or the Continuing Employee provides documentation of such deductibles and out-of-pocket charges to the Buyer in question’s carrier in a format useable by that carrier as soon as practicable after such Buyer Welfare Plan Start Date. It is hereby acknowledged and agreed that neither Buyer’s welfare benefit plans are, nor shall they become, by virtue of this Agreement or actions taken in compliance herewith, the successor to any welfare benefit plans of the Seller. It is also understood that each of the Buyers reserves the right to change, modify, discontinue or terminate any or all of its own welfare benefit plans at the discretion of the sponsoring Buyer at any time following the Closing Date.

          6.3.8 Vacation . With respect to each Continuing Employee, the Buyer that hires that Continuing Employee shall not assume such Continuing Employee’s unpaid, accrued vacation benefits under Seller’s or its Affiliate’s applicable vacation policy for the calendar year in which the Continuing Employee’s Employment Date occurs. As of the Continuing Employee’s Employment Date, the Continuing Employee will be entitled to vacation under the then applicable vacation policy or practices (as may be amended from time to time) of the Buyer that hired the Continuing Employee, which will recognize the number of years of service with the Seller and its Affiliates (and their affiliated predecessor entities) in determining the Continuing Employee’s vacation entitlement, including eligibility to participate and levels of vacation and vacation accrual. Vacation for the year in which the Continuing Employee’s Employment Date occurs under the applicable Buyer’s vacation policy or practices will be prorated based on the number of days from the Continuing Employee’s Employment Date to the last day of such year.

          6.3.9 Service Credit . Except as otherwise provided in this Agreement, for all purposes (including determining eligibility to participate and vesting and determining the level or amount of severance benefits), periods of service by a Continuing Employee with the Seller or its Affiliates (or any predecessor employer) prior to the Continuing Employee’s Employment Date that were recognized by the Seller and its Affiliates under Seller Plans shall be treated as service recognized under the analogous Buyer Plans of the Buyer that hires the Continuing Employee in question; provided , however , that such service shall not be recognized (a) for purposes of determining eligibility to participate in either Buyer’s retiree medical coverage plan, (b) for benefit accrual purposes under any Buyer Plan that is a qualified defined benefit pension plan, or (c) to the extent that such recognition would result in any duplication of benefits.

          6.3.10 Workers’ Compensation . The Seller shall retain all Liabilities of the Seller for workers’ compensation claims with respect to any Continuing Employee or his or her beneficiary if the incident or alleged incident giving rise to the claim occurred prior to his or her Employment Date. The Buyer who hires a Continuing Employee shall be responsible for any workers’ compensation claims with respect to that Continuing Employee or his or her beneficiary if the incident or alleged incident giving rise to the claim occurred on or after his or her Employment Date with the Buyer in question. In the event of doubt as to the date of the occurrence of the incident or alleged incident, the applicable Buyer shall process the claim; provided , however , that the Buyer shall be required to promptly inform the Seller of the existence and nature of any such claim and the Seller shall have the right to assist the Buyer in the processing of any such claim. Unless the Buyer who employs the Continuing Employee or its Affiliates is found to be liable for the incident in whole, the Seller shall pay or reimburse the Buyer for the payment of the claim and reasonable expenses of processing such claim in direct proportion to the percentage of the Seller’s Liability to the total amount of the Liability paid under the claim.

          6.3.11 Employee Information . The Parties agree to furnish each other with such information concerning employees and employee benefit plans, and to take all such other action, as is necessary and appropriate to effect the transactions contemplated by this Section 6.3 and permitted by Laws. Where any required information is in the possession of Third Parties

controlled by the Seller, such as insurers or trustees, the Seller shall use reasonable efforts to cause those Third Parties to cooperate in providing any such information to the applicable Buyer.

          6.3.12 No Third Party Beneficiaries; No Amendments to Plans . Nothing herein express or implied shall confer upon any employee, Continuing Employees or any other persons any rights or remedies, including any right to employment, or continued employment for any specified period, of any nature or kind whatsoever under or by reason of this Agreement. Nothing in this Agreement shall be construed to create any obligation to any third party on the part of any Buyer as a successor employer of Seller with respect to any collective bargaining agreement or obligation. Nothing in this Agreement shall constitute an amendment to, or be construed as amending, any benefit plan, program or agreement sponsored, maintained or contributed to by the Seller, either Buyer or any of their respective Affiliates.

          6.3.13 COBRA Continuation Coverage . The Seller will be responsible for providing any continuation coverage as required by COBRA (“ COBRA Continuation Coverage ”) for all employees, former employees, and their dependents where the qualifying event as defined in Section 4980B of the Code (the “ Qualifying Event ”) occurs before the applicable Employment Date.

Should either or both of the U.S. Department of Justice or ODEQ not execute the joint motion, then the Seller and the Buyers shall execute the joint motion and the Seller shall thereafter file the motion with the Global CAA Consent Decree Court.

               6.7.1.2 From and after the Closing Date, and subject to Section 6.7.1.7 below, the Seller shall be responsible for completion of each of the capital improvement projects described on Schedule 6.7.1.2 (the “ Environmental Compliance Projects ”), including the timely construction, installing, commissioning, start-up, performance testing and other demonstrations of compliance with emission limitations and reductions associated with those improvements listed on Schedule 6.7.1.2 in compliance with the Tulsa Global CAA Consent Decree Obligations relating to the Environmental Compliance Projects. The Parties shall use diligent and good faith efforts to appropriately establish reasonable standards for all of the foregoing requirements (including, for example, the identification of reasonable, shorter alternatives to lengthy testing and/or demonstration requirements under the Tulsa Global CAA Consent Decree Obligations). The Environmental Compliance Projects and Seller’s obligations pursuant to this Section 6.7.1.2 shall be deemed to have been completed when all of the Environmental Compliance Projects have each achieved Final Completion, and upon payment of the amounts provided for in Section 6.7.1.3(a), (b) and (c), Buyer shall be deemed to have accepted that Final Completion has occurred; provided that nothing herein shall constitute a waiver of any contractual right, claim, warranty, guarantee from or with any Third Party in relation to the Environmental Compliance Projects.

               6.7.1.3 Holly Tulsa shall pay to the Seller the following amounts in connection with the Environmental Compliance Projects (the “ Capex Amounts ”):

                    (a) Ten Million Dollars ($10,000,000) payable either (i) at Closing, if Mechanical Completion of each of the Wet Gas Scrubber, SCR on boilers numbers 1 through 3, the wastewater treatment plant modifications, and the Flare gas recovery system has occurred prior to Closing, or (ii) fifteen (15) days following Mechanical Completion of all such projects, if Mechanical Completion of such projects occurs any time following the Closing Date;

                    (b) Five Million Five Hundred Thousand Dollars ($5,500,000) within fifteen (15) days after Final Completion of those portions of the Environmental Compliance Projects identified in Section 6.7.1.3(a) and the SCR on boiler number 4;

                    (c) Five Hundred Thousand Dollars ($500,000) within fifteen (15) days after Final Completion of all Environmental Compliance Projects; and

For the avoidance of doubt, Seller shall pay, and shall be solely responsible for, all amounts relating to the costs of the Environmental Compliance Projects that exceed $17,000,000.

               6.7.1.4 For purposes of this Agreement, the term “Qualified Capital Expenses” means all Environmental Compliance Projects related capital expenditures that the Seller reasonably incurs on or after July 1, 2009 with respect to the Facilities and Other Assets for materials and services purchased by the Seller from third parties which expenses (i) are required to be capitalized under GAAP; (ii) are necessary and appropriate to complete the Environmental Compliance Projects as described on Schedule 6.7.1.2 ; (iii) in the case of purchases from Affiliates of the Seller, are on pricing and other terms commensurate with arms-length transactions between unrelated parties; and (iv) are consistent with the applicable Environmental Compliance Projects Contracts related to such materials and services. In the case of purchases of Environmental Compliance Projects related materials, the Seller will be deemed to have incurred the expense in question on the date the materials in question were received by the Seller. In the case of Environmental Compliance Projects related services, the Seller will be deemed to have incurred the expense on the date the service in question is rendered. Accordingly, the portion of any capital expenditures for Environmental Compliance Projects related materials received by the Seller prior to July 1, 2009 or Environmental Compliance Projects related services with respect to the Facility rendered prior to July 1, 2009 are not Qualified Capital Expenses. For purposes of clarity, Qualified Capital Expenses of the Seller shall include progress payments due and paid on or after July 1, 2009 with respect to capital equipment purchased for the Environmental Compliance Projects with respect to the Facility, but only to the extent any such progress payment is attributable to work performed or materials received on or after July 1, 2009.

               6.7.1.5 Within forty-five (45) days after Final Completion, the Seller shall provide to Holly Tulsa a reasonably detailed statement (the “ Capex Statement ”) setting forth the Seller’s calculation of the Capex Amounts payable by Holly Tulsa under Section 6.7.1.3(d) , and itemizing and describing all Qualified Capital Expenses incurred by the Seller on and after July 1, 2009 (including the dates such expenses were incurred and paid, the nature of the materials or services obtained, the amounts paid therefor, and the names of the applicable vendors). The Capex Statement shall be accompanied by copies of the applicable vendor invoices for the expenses shown, a listing of the dates the materials in question were received or the services in question were rendered, evidence that all vendors, contractors and other persons providing any work, equipment, materials services or labor and who might be able to file a lien against the Facilities have been paid in full or will be paid in full out of the payment in Section 6.7.1.3(d), and such other supporting documentation as Holly Tulsa reasonably requests provided that the Seller may contest in good faith any amounts claimed due to a vendor or contractor if the Seller provides a bond or other financial assurance reasonably acceptable to the Buyers that protects the Buyers and the Assets from any Damages related to such claim. In the event that Holly Tulsa objects to the Seller’s calculation of the Capex Amounts in the Capex Statement, the Parties shall promptly attempt to resolve their unresolved differences as to the Capex Amounts. Upon reasonable advance notice, Buyers shall have the right to inspect and copy any of the Sellers’ books and records relating to Qualified Capital Expenses, Mechanical Completion and Final Completion. If any portion of the Capex Amounts remains in dispute on the eightieth (80th) day following completion of the Environmental Compliance Projects, such disputed

portion shall be resolved in accordance with the arbitration provisions of Section 2.6.4.1 and paid within thirty (30) days after the final arbitration decision is rendered.

               6.7.1.6. [Intentionally omitted].

               6.7.1.7. If any of the Environmental Compliance Projects or other Equipment present at the Facilities or Tulsa Refinery that is required for compliance with the Tulsa Global CAA Consent Decree do not pass or satisfy the performance tests and other demonstrations of compliance with emission limitations and reductions specified under the limitations or requirements (if any) imposed under the Tulsa Global CAA Consent Decree Obligations by the Applicable CAA Deadline for reasons not attributable to the fault of Buyers or their Affiliates, the Seller shall reimburse each Buyer for any fines or penalties that may be imposed on such Buyer as a consequence of such failures and for any resulting additional costs incurred by the Buyers to meet the Tulsa Global Consent Decree Obligations in relation to such failure, but Seller shall not be responsible for any consequential damages including lost profits unless such damages are recoverable from a Third Party. Additionally, if the Seller does not complete any phase of the Environmental Compliance Projects by the Applicable CAA Deadline for reasons not attributable to the fault of Buyers or their Affiliates, and such failure has or may result in fines, penalties, or enforcement action pursuant to Tulsa Global CAA Consent Decree, Holly Tulsa at its option may assume management, control and oversight over the Environmental Compliance Projects.

               6.7.1.8 If Holly Tulsa assumes management and control over the completion of the Environmental Compliance Projects in accordance with Section 6.7.1.7 or the Seller otherwise defaults on its obligations under Section 6.7.1.2 to successfully complete the Environmental Compliance Projects by the Applicable CAA Deadlines, the Seller shall within thirty (30) days after written request from Holly Tulsa reimburse Holly Tulsa for all costs (properly capitalized under GAAP) that Buyers or their Affiliates reasonably incur to complete the Environmental Compliance Projects to the extent that: (i) the sum of such costs of completion, plus all amounts paid or payable by Holly Tulsa to the Seller under Section 6.7.1.3 and Section 6.7.1.6 . exceed (ii) Sixteen Million Dollars ($16,000,000). Any request for reimbursement by Holly Tulsa hereunder shall be accompanied by reasonable documentation of the costs of completion for which reimbursement is sought.

               6.7.1.9 Upon written request to the Seller, the Seller shall assign to Holly Tulsa all of the Sellers’ rights, but not its obligations, under any or all of the Environmental Compliance Projects Contracts in accordance with the form of Assignment of Rights attached hereto as Exhibit J .

               6.7.1.10 Prior to Final Completion of the Environmental Compliance Projects, Seller and its contractors shall have a license to enter on the Owned Real Property for the purpose of achieving Mechanical Completion and Final Completion of the Environmental Projects. Such access shall be subject at all times to applicable Laws and Buyers’ rules and regulations relating to health, safety, environment, indemnification and insurance that are generally applicable to contractor’s entering the Owned Real Property. Such license shall automatically terminate upon the first to occur of (i) Final Completion of the Environmental Compliance Projects, or (ii) the exercise by Holly Tulsa of its rights pursuant to Section 6.7.1.7.

If an Environmental Permit cannot be transferred from the Seller to the applicable Buyer effective as of the Closing Date, then Seller hereby grants to that Buyer the right to operate the Assets in question under Seller’s Environmental Permit; provided , however , that Seller shall have no responsibility or liability with respect to any violation of any such Environmental Permit occurring on or after the Closing Date and the applicable Buyer shall indemnify and hold harmless Seller with respect to any and all Liabilities arising from any such violations except as provided for in Section 6.7.1.2 .

Holly Tulsa shall also keep the Seller advised of its progress in performing any Remedial Work by promptly providing the Seller with copies of material, non-privileged reports to and correspondence with Third Parties and Governmental Authorities relating to the Remedial Work. To the extent practicable, prior to proposing any particular remedy or remedial action to any Governmental Authority, Holly Tulsa shall confer with the Seller regarding the action to be taken and shall incorporate to the extent reasonable the Seller’s comments with respect to the proposed action before proceeding to communicate with the Governmental Authority.

               8.3.1.1 any inaccuracy or breach of any representation or warranty made by Holly Tulsa under this Agreement or in any other document or certificate delivered by or on behalf of Holly Tulsa or any of its Affiliates pursuant to this Agreement;

               8.3.1.2 any breach of, or failure to perform, any covenant or agreement made by Holly Tulsa or any of Holly Tulsa’s Affiliates under this Agreement (including this Article 8 ) or in any other document or certificate delivered by or on behalf of Holly Tulsa or any of Holly Tulsa’s Affiliates pursuant to this Agreement; or

               8.3.1.3 any of the Assumed Liabilities other than those for which HEP Tulsa is responsible under Section 2.3 .

               8.3.2.1 any inaccuracy or breach of any representation or warranty made by HEP Tulsa under this Agreement or in any other document or certificate delivered by or on behalf of HEP Tulsa or any of its Affiliates pursuant to this Agreement;

               8.3.2.2 any breach of, or failure to perform, any covenant or agreement made by HEP Tulsa or any of HEP Tulsa’s Affiliates under this Agreement (including this Article 8 ) or in any other document or certificate delivered by or on behalf of HEP Tulsa or any of HEP Tulsa’s Affiliates pursuant to this Agreement; or

               8.3.2.3 any of the Assumed Liabilities for which HEP Tulsa is responsible under Section 2.3 .

          Section 8.4 Limitations of Liability . Notwithstanding the foregoing or anything herein provided to the contrary:

               8.4.1 subject to Section 8.4.10 , no Buyer Indemnified Party or Seller Indemnified Party seeking indemnification under Section 8.2 or Section 8.3 shall make any claim for indemnification, and shall not be entitled to indemnification, for any claim involving less than $200,000 of Damages arising out of any single occurrence or matter or series of related or similar occurrences or matters (“ Minor Claims ”); provided, however that the foregoing shall not apply to any claim for indemnification asserted insofar as such claims relate to any breach of a Fundamental Representation; provided further , however, that the foregoing shall also not apply to any claim for indemnification asserted insofar as such claim relates to any breach of a representation or warranty qualified by the term “material”;

               8.4.2 subject to Section 8.4.10 , no indemnification shall be payable pursuant to:

               8.4.2.1 Section 8.2.1 unless and until the total of all Damages for which the Seller would otherwise have an indemnification obligation under such Section exceeds $1,500,000 in the aggregate (the “ Threshold Amount ”), whereupon the Indemnified Party may claim indemnification for the amount, if any, in excess of the Threshold Amount. Notwithstanding the foregoing, such Threshold Amount shall not apply to any claims asserted under Section 8.2 insofar as such claims relate to any breach of a Fundamental Representation or any certificate based on such representations or warranties.

               8.4.2.2 Section 8.3.1 or Section 8.3.2 unless and until the total of all Damages for which either of the Buyers would otherwise have indemnification obligations under such Sections exceeds the Threshold Amount, whereupon the Indemnified Party may claim indemnification for the amount, if any, in excess of the Threshold Amount. For the avoidance of doubt, the Threshold Amount pursuant to this Section 8.4.2.2 is an aggregate amount shared by the Buyers. The Threshold Amount shall be applied to indemnification claims in the order in which they are asserted by Indemnified Parties. For example, if the first indemnification claim made under Section 8.3 was for $1,000,000 pursuant to Section 8.3.1 and a second indemnification claim was made for $750,000 pursuant to Section 8.3.2 , the Threshold Amount would apply to the entire first claim and to $500,000 of the second claim, at which point the Threshold Amount pursuant to this Section 8.4.2.2 would be exhausted and $250,000 would be payable to the Indemnified Party under the second claim. Notwithstanding the foregoing, such Threshold Amount shall not apply to any claims asserted under Section 8.3 insofar as such claims relate to any breach of a Fundamental Representation or any certificate based on such representations or warranties;

               8.4.3 subject to Section 8.4.10 , Indemnified Parties may not recover in the aggregate more than $45,000,000 (the “ Indemnity Cap ”) with respect to the following:

(a) for Buyer Indemnified Parties, pursuant to (i) Section 8.2.1.1 and (ii) Section 8.2.1.3 for Environmental Liabilities, including Retained Environmental Liabilities (provided that Retained Environmental Liabilities set forth in Sections 2.4.3.5, 2.4.3.6 and 2.4.3.7 are not subject to the foregoing cap and are unlimited); and

(b) for Seller Indemnified Parties, pursuant to Sections 8.3.1.1 and 8.3.2.1 .

For the avoidance of doubt, the Indemnity Cap applicable to Sections 8.3.1.1 and 8.3.2.1 is an aggregate amount shared by the Buyer Indemnified Parties. Indemnification claims shall be applied towards the Indemnity Cap in the order in

which they are asserted by Indemnified Parties. For example, if after application of the Minor Claim and Threshold Amount, the first indemnification claim made under Section 8.3 was for $40,000,000 pursuant to Section 8.3.1 and a second indemnification claim was made for $7,500,000 pursuant to Section 8.3.2 , the Indemnity Cap would apply to $2,500,000 of the second claim. Notwithstanding the foregoing, such Indemnity Cap shall not apply to (and the Indemnified Parties shall be entitled to be indemnified for all Damages relating to) any claims asserted under Article 8 insofar as such claims relate to any breach of a Fundamental Representation or any certificate based on such representations or warranties; provided , however , that in no event may Indemnified Parties recover in the aggregate an amount greater than $75,000,000 pursuant to Section 8.2 or pursuant to Section 8.3 ;

          8.4.4 no Buyer Indemnified Party shall be entitled to indemnification pursuant to this Agreement with respect to Damages to the extent such Damages result from or arise out of, or are attributable to, the coming into force of, or the change in any Environmental Law on or after the Closing Date;

          8.4.5 no Buyer Indemnified Party shall be entitled to indemnification pursuant to this Agreement with respect to any Damages that constitute, or for which the underlying event, effect, condition, fact, circumstance, or occurrence constitutes, Assumed Environmental Liabilities;

          8.4.6 no Buyer Indemnified Party shall be entitled to indemnification pursuant to this Agreement with respect to Damages to the extent such Damages that result from, arise out of or are otherwise incurred as a result of (i) any sampling or other investigation of environmental conditions by any Buyer Indemnified Party or anyone acting on their behalf, except for those investigations that are performed under the Prudent Businessman Standard or are required to be performed pursuant to applicable Environmental Laws or pursuant to the order or directive of a Governmental Authority, (ii) any investigation, claim or proceeding initiated or instituted by any Governmental Authority that is instigated or encouraged, directly or indirectly, by a Buyer Indemnified Party, unless such claim or proceeding arose out of the submission of a report to a Governmental Authority that was required by applicable Environmental Laws, (iii) any shutdown of or discontinuation of operations at any Facility or any change in use of any of the Assets after the Closing Date;

          8.4.7 no Buyer Indemnified Party shall be entitled to indemnification pursuant to this Agreement with respect to any Retained Environmental Liability pursuant to Section 8.2.1.3 or otherwise in respect of any Environmental Liability pursuant to Section 8.2 unless a Claim Notice relating thereto has been delivered to the Seller within ten (10) years following the Closing Date, except that the foregoing limitation shall not apply to the extent that any such claim results or arises from, or is attributable to, a breach by Seller of its obligations under the covenants in Sections 5.12, 6.7.5, 6.7.6, 6.12, 6.16 or 6.17 or is a claim for indemnification pursuant to Section 8.2.1.3 with respect to those Retained Environmental Liabilities identified in Sections 2.4.3.5, 2.4.3.6 or 2.4.3.7;

          8.4.8 if title to the Owned Real Properties is affected by matters that are recorded in the real estate records for Tulsa County, Oklahoma and that are not reflected as exceptions on the owner’s policy of title insurance obtained by the Buyer of that property, then the applicable Buyer agrees that it shall first pursue diligently its rights and remedies against the title insurer and only pursue the Seller for breach of representations and warranties contained in Section 4.1.1.1 with respect to such matters or pursuant to the applicable deed with respect to

such matters to the extent of recoverable Damages in excess of applicable insurance proceeds with respect to any such matters;

          8.4.9 if any Damages that are asserted against, imposed upon, incurred by or suffered by a Buyer Indemnified Party other than Holly Tulsa relate to or result from any Retained Environmental Liability or any breach by the Seller of any of the representations and warranties contained in Section 4.1.8 , any of Seller’s covenants under Sections 6.7.1 , 6.12 , 6.16 or 6.17 or any other express obligation of Seller under this Agreement related to environmental matters with respect to which a Buyer Indemnified Party is entitled to indemnification (“ Buyer Environmental Damages ”), Holly Tulsa may directly file and pursue a claim for indemnification under Section 8.2 with respect to such Buyer Environmental Damages in place of the Buyer Indemnified Party that incurred or suffered such Damages as long as such proceeds are applied toward the claim for which such indemnification has been requested. If Holly Tulsa files and pursues a claim for indemnification for Buyer Environmental Damages in place of another Buyer Indemnified Party: (i) any amounts paid by Seller for the Buyer Environmental Damages in question shall be paid to and may be retained by Holly Tulsa; (ii) the Buyer Indemnified Party that actually incurred the Buyer Environmental Damages in question shall be deemed to have assigned all of its indemnification rights against Seller with respect to such Damages to Holly Tulsa; (iii) each of Holly Tulsa and the Buyer Indemnified Party that incurred such Buyer Environmental Damages shall be considered an “Indemnified Party” for purposes of applying the provisions of Sections 8.6 through Section 8.8 ; and (iv) the fact that a Buyer Indemnified Party other than Holly Tulsa actually incurred the Buyer Environmental Damages in question shall not bar Holly Tulsa from receiving amounts from the Seller for such Damages; provided that nothing herein shall (a) obligate the Seller to make or provide duplicative payments with respect to any Buyer Environmental Damages or (b) increase or expand the Seller’s indemnity obligations pursuant to this Agreement; and

     Section 8.5 Exclusive Remedy .

          8.5.1 The Parties acknowledge and agree that, subject to Section 8.5.2 , the indemnification provisions in this Article 8 and the indemnification provisions in Article 10 shall be the exclusive remedies of the Seller, the Seller Indemnified Parties and their Affiliates, on the one hand, and the Buyers, the Buyer Indemnified Parties and their Affiliates, on the other hand, with respect to claims for Damages or otherwise, in connection with, arising out of or resulting from the transactions contemplated by this Agreement. Each Party agrees that nothing in this Section 8.5 shall limit or otherwise affect any nonmonetary right or remedy that any Party may have under this Agreement or otherwise limit or affect any Party’s right to seek equitable relief, including the remedy of specific performance for nonmonetary relief. Except as otherwise provided in this Agreement, the Seller on the one hand, and Buyers, on the other hand, hereby waive to the fullest extent permitted under applicable Laws, any and all rights, claims and causes of action they may have against the other relating to the subject matter of this Agreement and the other agreements contemplated hereby arising under or based on any Laws or otherwise, including such rights, claims and causes of action either Buyer may have against Seller under CERCLA, breaches of statutory or implied warranties or otherwise, nuisance or other tort actions, and common law rights of contribution. Without limiting the generality of the foregoing, each Buyer understands and agrees that the rights accorded under this Article 8 are its sole and exclusive remedy against Seller or any of its Affiliates with respect to the Assets or Facilities relating to Environmental Laws. Each Buyer hereby waives any right to seek contribution or other recovery from Seller or any of its Affiliates with respect to the Assets or Facilities under Environmental Laws, and each Buyer hereby releases Seller and its Affiliates from any claims, demands or causes of action that either Buyer has or may have in the future against Seller and/or its Affiliates with respect to the Assets or Facilities under Environmental Laws.

          8.5.2 Notwithstanding anything to the contrary contained in this Agreement or any documents or certificates delivered in connection with this Agreement, nothing in this Agreement or any documents or certificates delivered in connection with this Agreement (including Section 8.5.1 ) shall limit any liability for Fraud and Section 8.9 (Limitation of Damages) shall not apply to liabilities for Fraud.

     Section 8.6 Third Party Claims .

          8.6.1 If any Third Party shall notify any Party with respect to any action or claim by a Third Party (a “ Third Party Claim ”) that may give rise to a right to claim for indemnification against any other Party under Section 8.2 or 8.3 , then the Indemnified Party shall promptly notify the Indemnifying Party thereof in writing (which notice shall describe the Third Party Claim in reasonable detail, to the extent known, and shall indicate the amount (estimated, if necessary, and if then estimable) of the Damages that have been or may be suffered) (the “ Third Party Claim Notice ”); provided , however , that failure to give timely notice shall not affect the right to indemnification to the extent such failure to give timely notice is not prejudicial to the Indemnifying Party. Each Indemnifying Party to which a Third Party Claim Notice is given shall respond to any Indemnified Party that has given a Third Party Claim Notice (a “ Third Party Claim Response ”) within thirty (30) days (the “ Third Party Response Period ”) after the date that the Third Party Claim Notice is given. Any Third Party Claim Notice or Third Party Claim Response shall be given in accordance with the notice requirements hereunder, and any Third

Party Claim Response shall specify whether or not the Indemnifying Party giving the Third Party Claim Response disputes, or reserves its right to dispute, the claim for indemnification described in the Third Party Claim Notice and whether, if permitted under this Agreement, it will defend any Third Party Claim specified in such Claim Notice at its own cost and expense, which defense may be with a reservation of rights to deny liability under this Agreement or otherwise. If any Indemnifying Party fails to give a Third Party Claim Response within the Third Party Response Period, such Indemnifying Party shall be deemed to have elected not to assume the defense of such Third Party Claim. The Indemnified Party shall promptly deliver to the Indemnifying Party copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim.

          8.6.2 If a Third Party Claim is made against an Indemnified Party, the Indemnified Party shall permit, upon the written request of the Indemnifying Party, the Indemnifying Party to assume the defense thereof (it being understood that the Indemnified Party shall control such defense unless the Indemnifying Party assumes (if permitted under this Agreement) the defense of the Third Party Claim and it being understood that the Indemnifying Party may assume such defense with a reservation of rights to deny liability under this Agreement or otherwise); provided that, (a) the Indemnifying Party’s selected counsel must be reasonably satisfactory to the Indemnified Party, (b) the Third Party Claim does not seek to impose any Liability on the Indemnified Party other than money damages, and (c) the Third Party Claim is not a separable part of a larger claim or series of related claims that do not relate to Damages hereunder. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party, it being understood, however, that if the Indemnifying Party has properly assumed the defense in accordance with this Agreement, the Indemnifying Party shall control such defense subject to the obligation of the Indemnifying Party and the Indemnified Party to cooperate in the defense of such Third Party Claim as provided below. If it is determined that the Indemnifying Party has an obligation under this Agreement to indemnify the Indemnified Party, the Indemnifying Party shall be liable for the reasonable fees and expenses of one counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof in accordance with this Agreement or during the period in which the Indemnified Party’s legal counsel shall have advised the Indemnified Party in writing, with a copy delivered to the Indemnifying Party, that there exists one or more legal or equitable defenses available to them or that a conflict of interest exists that in either case would make it inappropriate under applicable standards of professional conduct to have common counsel. If the Indemnifying Party chooses to defend any Third Party Claim in accordance with this Agreement, the Parties shall reasonably cooperate in the defense or prosecution of such Third Party Claim. Such cooperation shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information that are reasonably relevant to such Third Party Claim and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (not to be unreasonably withheld, conditioned or delayed) unless the judgment or proposed settlement involves only the payment of money damages by the Indemnifying Party, does not impose an injunction or other equitable relief or

any other obligations upon the Indemnified Party, and provides for the full, final and unqualified release of the Indemnified Party in respect of such Third Party Claim.

          8.6.3 Unless and until the Indemnifying Party assumes the defense of the Third Party Claim as provided in Section 8.6.2 , the Indemnified Party may defend against the Third Party Claim in any commercially reasonable manner, which shall be for the account of the Indemnifying Party assuming that such Third Party Claim is covered by the Indemnifying Party’s indemnification obligations under this Agreement.

          8.6.4 If the Indemnifying Party assumes the defense of the Third Party Claim as provided in Section 8.6.2 , then in no event will the Indemnified Party consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed.

          8.6.5 If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim that the Indemnifying Party elects to contest; provided , however , that such cooperation shall not include the making of any related counterclaim or cross-complaint against any Person.

          8.6.6 The Party that is conducting the defense against the Third Party Claim shall provide each other Party such information possessed by the Party that is conducting such defense as such other Party shall reasonably request with respect to the Third Party Claim and the defense thereof to the extent such information may be provided without contractual liability to the defending Party or waiver of attorney-client privilege.

     Section 8.7 Direct Claims . The Party seeking indemnification under Section 8.2 or 8.3 (the “ Indemnified Party ”) for a claim that is not a Third Party Claim may make claims for indemnification hereunder by giving written notice (a “ Claim Notice ”) to the Party required to provide indemnification hereunder (the “ Indemnifying Party ”). Such notice shall briefly explain the nature of the claim in reasonable detail and the parties known to be involved, and shall specify the amount thereof (estimated, if necessary, and if then estimable). Subject to Section 8.1, the failure to give a Claim Notice on a timely basis shall not affect the indemnification provided hereunder except to the extent that the failure to give timely notice is prejudicial to the Indemnifying Party. Each Indemnifying Party to which a Claim Notice is given shall respond to any Indemnified Party that has given a Claim Notice (a “ Claim Response ”) within thirty (30) days (the “ Response Period ”) after the date that the Claim Notice is given. Any Claim Notice or Claim Response shall be given in accordance with the notice requirements hereunder, and any Claim Response shall specify whether or not the Indemnifying Party giving the Claim Response disputes the claim for indemnification described in the Claim Notice. The failure of any Indemnifying Party to give a Claim Response within the Response Period, shall not affect the right of such Indemnifying Party to dispute the claim of indemnification described in the Claim Notice to the extent such failure to give such Claim Response is not prejudicial to the Indemnified Party.

     Section 8.8 Determination of Amount of Damages; Mitigation . Except as provided in Section 8.5.2 , the Damages giving rise to any indemnification obligation hereunder shall be limited to the actual loss suffered by the Indemnified Party and shall be reduced by any insurance proceeds or other payment or monetary recoupment received or that may be realized or retained (including tax benefits that may be realized or retained) by the Indemnified Party as a result of the events giving rise to the claim for indemnification. Any Indemnified Party that becomes aware of Damages for which it intends to seek indemnification hereunder shall use commercially reasonable efforts to collect any amounts to which it may be entitled under insurance policies or from third parties (pursuant to indemnification agreements or otherwise) and shall use commercially reasonable efforts to mitigate such Damages.

     Section 8.9 Limitation of Damages . NOTWITHSTANDING ANYTHING CONTAINED TO THE CONTRARY IN ANY OTHER PROVISION OF THIS AGREEMENT AND EXCEPT FOR CLAIMS MADE BY THIRD PARTIES THAT SHALL NOT BE LIMITED BY THIS PARAGRAPH, THE PARTIES AGREE THAT THE INDEMNIFICATION OBLIGATIONS OF EACH PARTY, AND THE RECOVERY BY ANY PARTY OR INDEMNITEE OF ANY COVERED LIABILITIES 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 OR INDEMNITEE BE ENTITLED TO RECOVER, ANY INDIRECT, CONSEQUENTIAL, SPECIAL, EXEMPLARY OR PUNITIVE DAMAGES (INCLUDING ANY DAMAGES ON ACCOUNT OF LOST PROFITS OR OPPORTUNITIES OR BUSINESS INTERRUPTION OR DIMINUTION IN VALUE) SUFFERED OR INCURRED BY ANY PARTY OR INDEMNITEE.

     Section 8.10 Tax Treatment of Indemnity Payments . All indemnification payments made under this Agreement shall be treated as purchase price adjustments for Tax purposes to the extent permitted under applicable Laws.

conveyance of the Assets shall be the liability of the Buyer acquiring such Assets. The Seller and the Buyers agree that except for certain office furniture, computers and supplies as well as certain ancillary property, no OK Sales Tax will be collected and reported on any of the Assets transferred to the Buyers provided that such Assets fall within one of the above-mentioned exceptions to the OK Sales Tax.

If any exemption claimed by the Buyers or by the Seller is subsequently denied by any Taxing Authority and, as a result, the Seller is assessed additional Taxes, the Buyers shall reimburse the Seller, or its assignees, for such Taxes.

     Section 10.4 Oklahoma Realty Transfer Tax (Documentary Stamp Tax) . Each of the Buyers will be responsible for paying the Oklahoma Realty Transfer Tax (Documentary Stamp Tax) attributable to the filing of a deed recording the Buyer’s purchase of the Owned Real Property.

     Section 10.5 Oklahoma Motor Vehicle Excise Tax . Oklahoma imposes a Tax on the transfer of legal ownership of any registered motor vehicle. At Closing, the Seller shall not collect from the Buyers any excise Taxes on motor vehicles included in the Assets; rather, each of the Buyers shall remit such Taxes on the motor vehicles it has purchased to the appropriate Taxing Authorities when the Buyer retitles such motor vehicles. The Buyers agree to retitle the motor vehicles they purchase from Seller within thirty (30) days after the Closing Date.

     Section 10.6 Access to Information . After the Closing, the Seller shall grant to the Buyers (or their designees) access at all reasonable times to all of the information, books, and records relating to the Assets or the Business within the possession of the Seller (including Tax work papers and correspondence with Taxing Authorities), and shall afford the Buyers (or their designees) the right (at each Buyer’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit the Buyers (or their designees) to prepare Tax Returns and to conduct negotiations with Taxing Authorities. After the Closing, the Buyers shall grant to the Seller (or its designees) access at all reasonable times to all of the information, books and records relating to the Assets or the Business within the possession of the Buyers (including Tax work papers and correspondence with Taxing Authorities), and shall afford the Seller (or its designees) the right (at the Seller’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit the Seller (or its designees) to prepare Tax Returns and to conduct negotiations with Taxing Authorities.

     Section 10.7 Tax Indemnity . Notwithstanding any other provisions of this Agreement, Section 8.1 , this Section 10.7 and Section 10.8 shall apply to indemnification by the Seller to the Buyers for, and shall be the sole remedy of the Buyers in respect of, the Damages described in the following sentence. The Seller agrees to indemnify and hold harmless each of the Buyers

from and against the entirety of any and all Damages that the Buyers may suffer for (i) any breach of the representations and warranties found in Section 4.1.7 or the covenants of Seller contained in Section 10.1 through Section 10.6 and (ii) any Taxes attributable to the Assets or the Business with respect to any Tax year ending before the Closing Date or for any Tax year beginning before and ending on or after the Closing Date to the extent allocable (determined in a manner consistent with Section 10.1 ) to the portion of such period ending before the Closing Date. In no event shall the Seller’s obligation to indemnify the Buyers for any Damages under this Section 10.7 exceed the applicable Indemnity Cap (but subject to Section 8.5.2 ). No right to indemnity shall exist to the extent the Damages are the result of actions of the Buyers or their Affiliates.

     Section 10.8 Tax Indemnity Claims . The provisions of this Section 10.8 shall apply only to the indemnification provided for under Section 10.7 . If a claim for Taxes is made against any Buyer and if the Buyer intends to seek indemnity with respect thereto under Section 10.7 , the Buyer shall promptly furnish written notice to the Seller of such claim. Failure of the Buyer to so notify the Seller within sixty (60) days of the claim being made against the Buyer shall terminate all rights of the Buyer to indemnity by the Seller as to such claim to the extent the Seller’s position is prejudiced as a result thereof (whether due to an adverse effect on its ability to contest such claim or otherwise). The Seller shall have thirty (30) days after receipt of such notice to undertake, conduct, and control (through counsel of its own choosing and at its own expense) the settlement or defense thereof, and the Buyer in question shall cooperate with it in connection therewith. The Seller shall permit the Buyer to participate in such settlement or defense through counsel chosen by the Buyer (but the fees and expenses of such counsel shall be paid by the Buyer). So long as the Seller, at the Seller’s cost and expense, (i) has undertaken the defense of, and assumed full responsibility for all indemnified Damages with respect to, such claim, (ii) is reasonably contesting such claim in good faith by appropriate proceedings, and (iii) has taken such action (including the posting of a bond, deposit, or other security) as may be necessary to prevent any action to foreclose a lien against or attachment of the property of the Buyer seeking indemnity for payment of such claim, the Buyer shall not pay or settle any such claim. Notwithstanding compliance by the Seller with the preceding sentence, the Buyer in question shall have the right to pay or settle any such claim, but in such event it shall waive any right to indemnity by the Seller for such claim. If within thirty (30) days after the receipt of the Buyer’s notice of a claim of indemnity hereunder, the Seller does not notify the Buyer that it elects (at the Seller’s cost and expense) to undertake the defense thereof and assume full responsibility for all indemnified Damages with respect thereto, or, if the Seller gives such notice and thereafter fails to contest such claim in good faith or to prevent action to foreclose a lien against or attachment of the Buyer’s property as contemplated above, the Buyer shall have the right to contest, settle, or compromise such claim, and the Buyer shall not thereby waive any right to indemnity for such claim under this Agreement.

     Section 10.9 Tax Refunds . Refunds of Taxes paid or payable with respect to Taxes attributable to the Assets or the Business shall be promptly paid as follows (or to the extent payable but not paid due to offset against other Taxes shall be promptly paid by the Party receiving the benefit of the offset as follows): (i) to the Seller if attributable to Taxes with respect to any Tax period ending before the Closing Date or for any Tax period beginning before and ending on or after the Closing Date to the extent allocable (determined in a manner

consistent with Section 10.1 ) to the portion of such period ending before the Closing Date; and (ii) to the applicable Buyer if attributable to Taxes with respect to any Tax period beginning on or after the Closing Date or for any Tax period beginning before and ending on or after the Closing Date to the extent allocable (determined in a manner consistent with Section 10.1 ) to the portion of such period beginning on or after the Closing Date.

     Section 10.10 Certification of Nonforeign Status . On the Closing Date, the Seller shall deliver to each of the Buyers a certificate (in the form attached hereto as Exhibit F signed under penalties of perjury (i) stating that it is not a foreign corporation, foreign partnership, foreign trust or foreign estate, (ii) providing its U.S. Employer Identification Number, and (iii) providing its address, all pursuant to Section 1445 of the Code.

      WHEREAS , as a mutual inducement to the Parties to consummate the transactions contemplated in the ASPA, and in order to effect an efficient transition of the Assets and the Facilities from Provider to Buyers, the Parties desire to enter into this Agreement; and

      WHEREAS , in connection with the ASPA and the transactions contemplated therein, Buyers desire to retain Provider to perform and provide certain transition services to Buyers.

      NOW, THEREFORE , in consideration of the premises and the mutual promises contained herein, and for other good and valuable consideration, the receipt of which is hereby acknowledged, and intending to be legally bound hereby, the Parties agree as follows:

ARTICLE I

TRANSITION SERVICES

     1.1 Definitions . All capitalized terms used in this Agreement and not otherwise defined herein shall have the meanings given them in the ASPA. Provider and Buyers are sometimes referred to herein together as the “Parties,” and each of Provider, on the one hand, and Buyers on the other hand, are individually referred to as a “Party.”

     1.2 Transition Services . This Agreement sets forth the terms and conditions for the provision by Provider to Buyers of certain transition services which are described on Schedule A attached hereto (the “ Transition Services ”). It is the intention of the Parties to cooperate with each other in effecting, as rapidly as is practicable and commercially reasonable after Closing, the separation of the Business from Seller and the transition of the Business to Buyers. Buyers agree to transition each of the Transition Services to its own internal organization or other third party providers as promptly as reasonably practicable, but in no case no later than the expiration of the Term of the applicable Transition Service.

     1.3 Engagement of Provider . Buyers hereby engage Provider to provide the Transition Services, and Provider hereby accepts its engagement by Buyers.

     1.4 Term . The term of this Agreement (the “ Term ”) shall commence as of the Closing Date and shall continue until the expiration of the terms of all of the Transition Services as set forth

on Schedule A (the “ Expiration Date ”), subject to earlier termination pursuant to Article V or pursuant to written agreement by the Parties. The Term shall automatically terminate at such time as all Transition Services have been terminated.

     1.5 Provision of Transition Services .

     (a) Provider shall use its commercially reasonable efforts to provide or cause to be provided each Transition Service from the Closing Date for the time set forth on Schedule A , except (i) as automatically modified by termination of a particular Transition Service by Buyers in accordance with this Agreement, (ii) as otherwise agreed to by the Parties in writing, or (iii) in the event of the earlier termination of this Agreement.

     (b) Provider shall provide the Transition Services to Buyers through Dedicated Employees (defined below) and Other Employees (defined below). Provider shall be entitled to rely upon any written or oral instructions received from Buyers’ designated representatives relating to the Transition Services. The quantity or quality of Transition Services provided by Provider will be limited to the services provided by the Dedicated Employees and Other Employees, and is not required to be higher than the quantity and quality of the same or similar services that Provider has historically provided with respect to the Assets and the Facilities.

     (c) Those employees of Provider who will devote 100% of their business time to the provision of Transition Services hereunder (each, a “ Dedicated Employee ”) are designated on Schedule A . If any Dedicated Employee’s employment with Provider is terminated for any reason, Provider will use commercially reasonable efforts to provide a replacement of such employee, who must be reasonably acceptable to Buyers; provided, however, that until such replacement has been approved by Buyers, Provider shall not be responsible for providing the Transition Services that were to be provided by the Dedicated Employee who is unavailable.

     (d) Provider may provide certain of the Transition Services through employees who are not Dedicated Employees and who will not devote 100% of their business time to the provision of Transition Services (“Other Employees”). The Other Employees might not be the same employees who provided the service to Provider and might be simultaneously involved in the conduct of other business for Provider and Provider’s Affiliates. Provider agrees to use reasonable efforts to have such Other Employees available to Buyers on an incidental and part-time basis throughout the Term of this Agreement; provided that Other Employees will not be required to forego their primary employment obligations with Provider and Provider’s Affiliates or otherwise take any actions which could have an adverse impact on the operations of Provider and Provider’s Affiliates.

     (e) Provider may, but will not be obligated to, provide or acquire equipment, computer programs, or outside service providers to enable Provider to provide the Transition Services, provided, that such service providers must be reasonably acceptable to Buyers, and Buyers will not be obligated to reimburse Provider for the costs of such equipment, programs or providers unless Buyers have agreed in advance in writing.

     (f) Any information provided by Provider, Dedicated Employees or Other Employees in the course of performing Transition Services shall be limited solely to factual

matters relating to the historical operation of the Facilities and the Business; and shall in no way constitute advisory or consulting services.

     (g) Buyers understand that the Transition Services provided hereunder are transitional in nature and are furnished by Provider for the purpose of facilitating the transactions contemplated by the ASPA. Buyers further understand that Provider is not in the business of providing Services to third parties and will not provide a Service beyond its applicable Term.

     (h) Buyers understand that certain Transition Services will be provided to it by Provider pursuant to agreements between Provider and various vendors. Buyers will reasonably cooperate with any third party providing such Transition Services on behalf of Provider in order to facilitate the provision and receipt of such Transition Services. Buyers acknowledge that such Transition Services are dependent on such cooperation, and that its failure to so cooperate shall relieve Provider of its obligation to provide the related Transition Services to the extent such failure renders such provision impractical or impossible.

     (i) Buyers will use commercially reasonable efforts to provide information, data and documentation that are necessary for Provider to provide the Transition Services. Buyers will provide such information, data and documentation in the format as reasonably requested by Provider. Buyers acknowledge that certain Transition Services are dependent upon such information and documentation, and that its failure to provide such information and documentation as set forth herein shall relieve Provider of its obligation to provide the related Transition Services to the extent such failure renders such provision impractical or impossible. Provider shall assist the Buyers in identifying which types of information and data are required for the provision of the Transition Services.

     (j) Buyers will reasonably cooperate with Provider in order to facilitate the provision and receipt of the Transition Services. Buyers acknowledge that such Transition Services are dependent on such cooperation, and that its failure to so cooperate shall relieve Provider of its obligation to provide the related Transition Services to the extent such failure renders such provision impractical or impossible.

     (k) Buyers will comply with all reasonable applicable policies and procedures of Provider that are provided in advance to Buyers in writing in connection with its receipt of the Transition Services.

     (l) PROVIDER SPECIFICALLY DISCLAIMS ANY REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED (i) RELATING TO THE TRANSITION SERVICES, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR A PARTICULAR PURPOSE; (ii) RELATING TO THE RESULTS TO BE OBTAINED FROM THE TRANSITION SERVICES; AND (iii) THAT THE TRANSITION SERVICES ARE ERROR-FREE OR NON-INTERRUPTIBLE.

     1.6 System Security.

     (a) If either Party is given access to the other Party’s computer systems or software (collectively, “ Systems ”) in connection with the Transition Services, the Party given access (“ Availed Party ”) shall comply with all of the other Party’s system security policies, procedures and requirements that have been provided to the Availed Party in advance and in writing (collectively, “ Security Regulations ”), and will not tamper with, compromise or circumvent any security or audit measures employed by such other Party. The Availed Party shall access and use only those Systems of the other Party for which it has been granted the right to access and use.

     (b) Each Party will use commercially reasonable efforts to ensure that only those of its personnel who are specifically authorized to have access to the Systems of the other Party gain such access, and use commercially reasonable efforts to prevent unauthorized access, use, destruction, alteration or loss of information contained therein, including notifying its personnel of the restrictions set forth in this Agreement and of the Security Regulations.

     (c) If, at any time, the Availed Party determines that any of its personnel has sought to circumvent, or has circumvented, the Security Regulations, that any unauthorized Availed Party personnel has accessed the Systems, or that any of its personnel has engaged in activities that may lead to the unauthorized access, use, destruction, alteration or loss of data, information or software of the other Party, the Availed Party shall immediately terminate any such person’s access to the Systems and immediately notify the other Party. In addition, such other Party shall have the right to deny personnel of the Availed Party access to its Systems upon notice to the Availed Party in the event that the other Party reasonably believes that such personnel have engaged in any of the activities set forth above in this Section 1.6 or otherwise pose a security concern. The Availed Party will use commercially reasonable efforts to cooperate with the other Party in investigating any apparent unauthorized access to such other Party’s Systems.

     (a) Buyers acknowledge that the Transition Services that are provided through third parties or using third party Intellectual Property are subject to external resources, which must contain a confidentiality agreement and other terms and conditions of any applicable agreements between Provider and such third parties, and Buyers agree to comply with such terms and conditions to the extent that Buyers are or have been made aware of them.

     (b) Provider shall use commercially reasonable efforts to obtain any consents from third parties that Provider believes are necessary in order to provide any of the Transition Services under this Agreement; provided, however, that Provider shall not be required to pay any fees to any third party to obtain such consent. In the event that Provider is unable to obtain any such consent, the Parties will work together to agree upon a commercially reasonable alternative arrangement, and any costs and expenses arising in connection therewith will be borne by Buyers.

     1.8 Purchase of Additional or Modified Transition Services . From time to time, Buyers may request that Provider provide additional or modified transition services that are not described on Schedule A . Provider will use commercially reasonable efforts to accommodate any reasonable

requests, but is not bound to provide such additional or modified transition services unless and until agreed to in writing by the Parties.

     (g) If Sinclair discovers, prior to delivery, that any Product tendered for delivery fails to comply with the Specifications (“ Off-Spec Product ”), Sinclair may reject such Product or, at its option and upon notice to Holly, may accept such Product, in which case price adjustments shall be made by mutual agreement.

ARTICLE III
PRODUCT PRICE; PAYMENT

     Section 3.1. Product Price . Sinclair shall pay Holly by wire transfer to the bank account designated by Holly from time to time the price (the “ Product Price ”) for all Products purchased and taken by Sinclair under this Agreement as follows, without deduction, setoff or other reduction except as expressly provided herein:

          (a) For Product delivered into the Magellan Pipeline, the Product Price shall be determined based on a three day average (the “ Three Day Wrap ”) of the price of the Product, determined the day of, day before, and day after, the date of delivery (based on the beginning of pump into the Magellan Pipeline) (each of such three days being a “ Pipeline Pricing Day ”). If a Pipeline Pricing Day falls on a Saturday then the Pipeline Pricing Day for such delivery will be the preceding Friday. If a Pipeline Pricing Day falls on a Sunday then the Pipeline Pricing Day for such delivery shall be the following Monday. If a Pipeline Pricing Day falls on a holiday where no pricing is available, then the Pipeline Pricing Day for such delivery shall be the nearest pricing day. If there is a tie, the Pipeline Pricing Day for such delivery shall roll forward to the next pricing day. Subject to the provisions above, the price of the Product for each Pipeline Pricing Day in a Three Day Wrap used to determine the Product Price shall be determined in accordance with Exhibit D .

          (b) For Product delivered at the Tulsa Rack, the Product Price shall be the price of the Product for the date of delivery (the “ Rack Pricing Day ”) determined in accordance with Exhibit D . If a Rack Pricing Day falls on a Saturday or Sunday, then the Rack Pricing Day for such delivery will be the immediately preceding Friday. If the Rack Pricing Day falls on a

holiday where no pricing is available, then the Rack Pricing Day for such delivery shall be the immediately preceding pricing day.

     Section 3.2. Additives .

          (a) Sinclair Additives may be provided by Sinclair to Holly prior to delivery of the Products. If Sinclair provides Holly with a Sinclair Additive for a Product, Holly shall inject such Sinclair Additive prior to delivery of such Product to Sinclair at Sinclair’s designated dosage. A fee of $0.0015/gallon of Product to which Sinclair Additives are added will be collected as an administrative fee by Holly from Sinclair for the amount of Sinclair Additives added to the Products. Sinclair shall be entitled to use the additive injection system and related equipment and storage facilities at the Tulsa Refinery for purposes of adding Sinclair Additives to the Products and Holly agrees to cooperate in good faith with Sinclair in connection with such activities.

          (b) If Holly provides a Sinclair Additive for a Product at Sinclair’s request, in addition to the administrative fee provided for in Section 3.2(a), Sinclair shall pay Holly for the cost of such Sinclair Additives plus a fee of $0.004/gallon of Product to which Sinclair Additives are added.

          (c) Sinclair shall provide Sinclair Additives for Holly’s use at Sinclair’s out of pocket third party cost for such Sinclair Additives plus 10%.

Sinclair shall pay undisputed amounts in Holly’s invoice by wire transfer not later than three days from the date of Holly’s invoice. Sinclair shall notify Holly with regard to any portion of Holly’s invoice which it disputes in good faith and the reasons therefore, not later than three Business Days following receipt of Holly’s invoice. Any overdue balance owed by a Party, except an amount that is disputed in good faith by said Party, shall accrue daily interest charges at a rate equal to the lesser of (i) 150% of the Bank Rate (as in effect on the past due date) calculated on the basis of a 360-day year and (ii) the maximum rate of interest permitted by applicable Law. Any overdue balance owed by a Party that is disputed by such Party in good faith shall bear interest at a rate equal to the lesser of (i) 100% of the Bank Rate (as in effect on the past due date) calculated on the basis of a 360-day year and (ii) the maximum rate of interest permitted by applicable Law. The Parties shall work together to resolve any invoice disputes by not later than two (2) days following the date payment was originally due. If a payment due date falls on a Saturday or a bank or federal holiday, other than Monday, the payment shall be due on the immediately preceding Business Day. If the payment due date falls on a Sunday or Monday bank or federal holiday, the payment shall be due on the following Business Day.

          (b) In addition to its other rights and remedies, in the event Sinclair fails to make any payment when due, Holly may (i) terminate this Agreement, in whole or in part,

forthwith and without notice if Sinclair does not pay all undisputed amounts due to Holly within thirty (30) calendar days after Holly’s exercise of Holly’s right of suspension under Section 3.3(b)(ii), (ii) if Sinclair does not pay to Holly all undisputed amounts within one (1) Business Day of a payment due date pursuant to the terms of this Section 3.3, suspend deliveries until all indebtedness is paid in full, and/or (iii) if Sinclair does not pay to Holly all undisputed amounts within one (1) Business Day of a payment due date pursuant to the terms of this Section 3.3, place Sinclair on a cash-on-delivery or prepayment basis.

     Section 3.4. Financial Responsibility . Prior to the Effective Date, Sinclair shall either: (i) pledge HOC Stock and/or HEP Units to Holly pursuant to a pledge and security agreement in a form mutually satisfactory to the Parties or (ii) provide letters of credit, cash collateral or other financial assurances, reasonably satisfactory to Holly to provide adequate assurances of Sinclair’s payment of amounts due or to become due under this Agreement. Upon Sinclair’s request, Holly shall periodically update its credit evaluation to determine, in Holly’s discretion reasonably exercised, an open credit limit, if any, to be granted to Sinclair or its guarantor hereunder. Sinclair shall promptly provide Holly with such financial and other information as Holly may reasonably request to allow Holly to update Holly’s credit evaluation. If Holly determines in good faith that changes to Sinclair’s financial condition warrant a change in Holly’s open credit limit, Holly will advise Sinclair of such and Sinclair shall increase or decrease its pledge of HOC Stock and/or HEP Units, letters of credit, cash collateral or other financial assurances accordingly.

     Section 3.5. Platts Product Price References . All references in this Agreement to “Platts Group 3 Spot” prices shall refer to the prices for Products published by Platts on the relevant day on page 18 of the Platts Global Alert for “Platts US Group 3 Product Assessments” (the “ Platts Index Page ”), two examples of which are attached as Exhibit E hereto. References in this Agreement to the “Platts Group 3 Spot Low” price shall refer to the low price quoted for a Product on the Platts Index Page on the relevant day. References in this Agreement to the “Platts Group 3 Spot Mean” price shall refer to the average of the low price and the high price quoted for a Product on the Platts Index Page on the relevant day.

     Section 3.6. Replacement Index .

          (a) Except as expressly set forth in Exhibit D , in the event that (i) the Platts Index Page ceases to exist or contain any of the data necessary to determine the Product Price in question for a Product, (ii) the Platts Index Page changes the basis for the determination of any of such data in a manner that is adverse to either of the Parties or (iii) there is a variation in the Products and the Platts Index Page does not publish a price for such Product, then the Product Price in question shall be based on such alternative publication, index or manner as most closely approximates the pricing methods then adopted by firms in the refining and marketing industry for deliveries at locations near the Delivery Point and as reasonably acceptable to both Holly and Sinclair. In the event that no agreement is reached regarding an alternative pricing method in such a situation, then the matter shall be referred to an Expert for determination in accordance with Section 10.3.

          (b) The Parties acknowledge this is a long-term refined products supply agreement and it is their intent for this Agreement to continue to apply if the Products listed in

Exhibit A are no longer produced at the Tulsa Refinery during the term of this Agreement as a result of market changes, changes in Law or other factors. If as a result of market changes, changes in Law or other factors, all or part of the Products listed in Exhibit A are no longer produced at the Tulsa Refinery, then the Parties agree that the new refined products produced at the Tulsa Refinery shall be made available for delivery to Sinclair and this Agreement shall continue to apply to such new refined products. If the Parties are unable to agree on the pricing and other arrangements for such new refined products, then the matter shall be referred to an Expert for determination in accordance with Section 10.3. Nothing in this Section 3.6(b) shall affect or diminish in any way the rights of the Parties pursuant to Article VII.

     Section 3.7. Adjustment . The fees provided for in Section 3.2(a), Section 3.2(b), Part 4 of Exhibit D and the Ethanol Fee are subject to adjustment as provided in this Section 3.7. Such fees will be adjusted each January 1 commencing January 1, 2011 to reflect any upward change in the annual change rounded to four decimal places of the Producer Price Index-Commodities — Finished Goods, (PPI), as revised, produced by the U.S. Department of Labor, Bureau of Labor Statistics. The series ID is WPUSOP3000 as of 10/1/2009 — located at http://www.bls.gov/data/ . The change factor (“ Change Factor ”) for the fees described in the first sentence of this Section 3.7 shall be equal to a percentage amount calculated as follows: the annual PPI index figure for the most current year less the annual PPI index figure for the immediately preceding year, which amount shall be divided by the annual PPI index figure for the immediately preceding year; provided the Change Factor in any year shall not be greater than four (4) percent. If the annual PPI index change in a given year from the immediately preceding year is negative, then the Change Factor will be deemed to be “zero.”

ARTICLE IV
DELIVERY POINT; PRODUCT MEASUREMENT

     Section 4.1. Delivery Point and Title and Risk of Loss . All Products shall be tendered by Holly and taken by Sinclair at the point where the Products pass from Holly’s delivery equipment at the Tulsa Refinery’s last outlet flange/Magellan Pipeline custody transfer meter into the Magellan Pipeline or into Sinclair’s (or Sinclair’s designees) railcars or truck transports at the Tulsa Rack (the “ Delivery Point ”). Title and risk of loss to Products shall pass from Holly to Sinclair at the Delivery Point. Sinclair shall coordinate the shipment of Product with Holly on a daily basis. Holly shall be responsible for scheduling all deliveries of Product into the Magellan Pipeline directly with Magellan. Sinclair shall be responsible for transportation of all Products from the Delivery Point, including contracting for all rail and truck transportation services, and such rail and truck transportation services shall meet Holly’s site access, insurance, safety and other requirements applicable to Persons entering the Tulsa Refinery generally.

     Section 4.2. Measurements and Tests .

          (a) Unless otherwise specified, quantities delivered (i) into transport trucks shall be measured by the calibrated weight scales or calibrated meters at the Tulsa Refinery; or (ii) into pipelines shall be measured by calibrated meters maintained by the Magellan Pipeline, or if such are not available, by terminal tank gauges. Upon reasonable prior notice to the other

Party, either Party may require presence of an independent petroleum inspector at the line of delivery. Such inspector shall be appointed jointly, and the cost of the inspector’s services shall be paid by the Party requiring the presence of the inspector. The inspector’s determinations shall be conclusive and binding upon both Parties. Each Party shall have the right, upon reasonable prior notice, to have a representative present to witness all gauges, tests, and measurements. In the absence of either Party’s representative, the gauges, tests and measurements of the other Party shall be deemed to be correct.

          (b) All measurements shall represent 100 percent volume, consisting of United States barrels of 42 gallons, the quantity and gravity of which will be adjusted to 60 degrees Fahrenheit temperature. Temperature corrections to 60 degrees Fahrenheit shall be made in accordance with the latest edition of Table 6A or 6B of the Petroleum Measurement Tables of the American Petroleum Institute (API) Standard 2540/American Society of Testing and Materials (ASTM) D 1250/Institute of Petroleum (IP) Designation 200, whichever is in use at the discharge terminal. Automatic temperature compensators for metered delivery are acceptable when in compliance with Table 6A or 6B, whichever applies, except where local Laws prohibit temperature correction for the Product, delivery method, and the Delivery Point.

          (c) Sinclair shall have the right, but not the duty, to inspect the Products prior to delivery. The warranties provided by Holly in Article V shall remain in effect if Sinclair exercises such inspection rights. Notwithstanding anything in this Agreement to the contrary, regardless of whether Sinclair exercises such inspection rights or if a quality issue arises after the Delivery Point, absent manifest error, Holly’s samples and quality results for any Product delivered at the Magellan Pipeline shall be binding on the Parties and shall govern any dispute with respect to such deliveries at the Magellan Pipeline accepted by Magellan. Samples of the Products shall be taken from the tank(s) or pipeline as appropriate. The sample shall be by line-sampling devices where available. Tests to determine quality shall be made from such samples and shall be made in accordance with standard test methods specified in the official publications of either the American Society for Testing and Materials (“ ASTM ”) or the American Petroleum Institute (“ API ”), whichever are in general use at the discharge terminal. Other appropriate test methods as mutually agreed may be used for the qualities where no methods are prescribed in ASTM or API publications on the delivery date. In any event, written notice of any claim which Sinclair may have relating to quantity or quality of Product in each delivery must be delivered to Holly within five Business Days after the date of delivery of the Product or such claim shall be deemed waived.

     Section 10.2. Allocation of RINs . If Sinclair generates RINs that Sinclair is entitled to in respect of the Products after delivery by Holly at the Delivery Point, Holly shall not be entitled to any of the benefits associated with such RINs until the later of January 1, 2011 or until the Tulsa Refinery no longer receives a “small refinery” exemption, at which time Sinclair shall provide Holly with 50% of the benefits associated with such RINs at no cost. In addition, Holly may purchase the 50% of such RINs retained by Sinclair at a mutually agreed market price.

     Section 10.3. Product Pricing . If at any time the standard practice in the industry provides for the Platts Group 3 Spot price to include the retention of RINs by a seller of the Products, then the Product Price under Section 10.1 or Section 10.2 shall be altered to be consistent with such industry standards. If Sinclair and Holly cannot agree on whether the Platts Group 3 Spot price is so set within ten (10) days after the request by either Party to do so, either Party may submit the matter to an expert (the “ Expert ”). The Expert shall be a firm or an individual having appropriate expertise in the refining and marketing industry as selected by the

mutual agreement of Holly and Sinclair or, if the Parties do not agree on such firm, as selected by a major accounting firm that is not then providing accounting services to either Party or its Affiliates. No Expert may have a relationship with either Party and must not have provided services to, or otherwise had any such relationship with, either Party within the five year period prior to its appointment. Any Person appointed or to be appointed as an Expert shall disclose to the Parties any circumstance likely to give rise to justifiable doubt as to the Expert’s impartiality or independence, including any bias or any financial or personal interest in the result of any matter referred to the Expert or any past or present relationship with the Parties or their representatives. The Parties shall cooperate with the Expert and shall provide the Expert access to such books and records as may be reasonably necessary to permit a determination by the Expert. The resolution by the Expert shall be final and binding on the Parties. The Expert shall use commercially reasonable efforts to complete its work within 30 days following its engagement. The expenses of the Expert shall be shared equally by Holly and Sinclair.

ARTICLE XI
CONFIDENTIALITY

     Section 11.1. Obligations . Each Party shall retain the other Parties’ Confidential Information in confidence and not disclose the same to any third party nor use the same, except as authorized by the disclosing Party in writing or as expressly permitted in this Article XI. Each Party further agrees to take the same care with the other Party’s Confidential Information as it does with its own, but in no event less than a reasonable degree of care.

          (c) is obtained by the receiving Party without an obligation of confidence from a third party who is rightfully in possession of such information and, to the receiving Party’s knowledge, is under no obligation of confidentiality to the disclosing Party; or

          (d) is independently developed by the receiving Party without reference to or use of the disclosing Party’s Confidential Information.

For the purpose of this Section 11.1, a specific item of Confidential Information shall not be deemed to be within the foregoing exceptions merely because it is embraced by, or underlies, more general information in the public domain or in the possession of the receiving Party.
