THE TRANSACTIONS

Section 2.1 Company Reorganization and Sinclair Contribution.

(a) Company Reorganization. Immediately prior to the execution of this Agreement, Sinclair HoldCo has executed and delivered the Reorganization Agreement, pursuant to which it has undertaken or will undertake various restructuring transactions. Following the date hereof, Sinclair HoldCo shall, and shall cause its Affiliates to, comply with the terms and conditions set forth in the Reorganization Agreement.

(b) Sinclair Contribution. Upon the terms and subject to the conditions set forth in this Agreement, at the Closing, Sinclair HoldCo shall contribute to HEP the Company LLC Interests in exchange for the consideration described in this Section 2.1(b) (the “Sinclair Contribution Consideration”). The aggregate consideration to be issued or paid by HEP to Sinclair HoldCo in connection with the Sinclair Contribution shall be (i) a number of HEP Common Units equal to 21,000,000, less the Divestiture Units, to the extent applicable in accordance with Section 2.1(f) (the “Sinclair Partnership Interest Consideration”), and (ii) an amount of cash equal to $325,000,000 (the “Base Cash Consideration”), (A) plus or minus the Estimated Adjustment Payment, which cash amount shall be subject to adjustment following the Closing pursuant to Section 2.2, and (B) if applicable, minus the Consent Adjustment.

(c) Equitable Adjustment. If, between the date of this Agreement and the Closing, the outstanding HEP Common Units shall have been changed into a different number of units or a different class of units by reason of any subdivision, reorganization, reclassification, recapitalization, combination or exchange of units, or any similar event shall have occurred, then the Sinclair Partnership Interest Consideration shall be equitably adjusted to proportionally reflect such change.

(d) Pre-Closing Statement; Payoff Letters. At least three (3) Business Days prior to the Closing Date, Sinclair HoldCo shall deliver to HEP a statement (the “Pre-Closing Statement”) setting forth its good faith estimates of the (i) (A) Closing Working Capital (the “Estimated Closing Working Capital”), (B) Closing Cash (the “Estimated Closing Cash”), and (C) Closing Indebtedness (the “Estimated Closing Indebtedness”), in each case, determined in accordance with the accounting principles set forth on Schedule 2.2(a) and in a format consistent with the illustrative calculation on Schedule 2.2(a), which assumes a Closing Date of December 31, 2020, and this Agreement, and (ii) the Estimated Adjustment Payment resulting from such estimates. At least three (3) Business Days prior to the Closing Date, Sinclair HoldCo shall deliver to HEP substantially final payoff letters for the Specified Funded Indebtedness (the “Payoff Letters”), which Payoff Letters shall authorize the release of all Encumbrances securing such Specified Funded Indebtedness upon payment of the applicable portion of the Indebtedness Payoff Amount in full at or prior to the Closing.

4

(e) Pre-Closing Cash Distribution, Issuance of Sinclair Partnership Interest Consideration and Payment of Base Cash Consideration and Estimated Adjustment Payment.

(i) At Closing, HEP shall deliver to Sinclair HoldCo the Sinclair Partnership Interest Consideration, in book-entry form.

(ii) If the Estimated Adjustment Payment is positive:

(A) prior to Closing, the Company shall distribute to Sinclair HoldCo an amount of cash equal to the lesser of (i) the Estimated Closing Cash and (ii) the Estimated Adjustment Payment; and

(B) at Closing, HEP shall pay to Sinclair HoldCo, by wire transfer of immediately available funds to an account designated by Sinclair HoldCo at least three (3) Business Days prior to the Closing Date, an amount of cash equal to the sum of the Base Cash Consideration and the excess, if any, of the Estimated Adjustment Payment over the amount distributed to Sinclair HoldCo pursuant to Section 2.1(e)(ii)(A).

(iii) If the Estimated Adjustment Payment is negative, at Closing, HEP shall pay to Sinclair HoldCo, by wire transfer of immediately available funds to an account designated by Sinclair HoldCo at least three (3) Business Days prior to the Closing Date, an amount of cash equal to the excess of the Base Cash Consideration over the Estimated Adjustment Payment.

(f) In the event of a UNEV Pipeline Divestiture Action, Sinclair HoldCo shall satisfy the Sinclair Divestiture Portion in accordance with this Section 2.1(f). Promptly following the date that the applicable HEP Entity enters into definitive agreements contemplating the UNEV Pipeline Divestiture Action, but no later than ten (10) Business Days prior to the Closing Date, HEP shall deliver a written notice (the “UNEV Pipeline Divestiture Notice”) to Sinclair HoldCo, which notice shall set forth the UNEV Pipeline Divestiture Proceeds and, in the event the UNEV Pipeline Divestiture Proceeds include (i) any non-cash consideration or (ii) any delayed, deferred or contingent consideration (other than customary post-closing adjustments for inventory and working capital) (collectively, “Other Consideration”), HEP’s good faith estimate of the fair market value of the Other Consideration, taking into account, in the case of clause (ii), the timing and likelihood of payment of such Other Consideration and such notice shall include in reasonable detail the basis for HEP’s calculation of such fair market value.

(i) In the event the UNEV Pipeline Divestiture Proceeds consist solely of cash payable at the closing of the UNEV Pipeline Divestiture Action and do not include any Other Consideration, then, HEP shall reduce the number of HEP Common Units to be issued at the Closing pursuant to Section 2.1(b) by the Divestiture Units.

(ii) In the event the UNEV Pipeline Divestiture Proceeds include any Other Consideration, then Sinclair HoldCo may, within five (5) Business Days after the UNEV Pipeline Divestiture Notice has been received by Sinclair HoldCo, dispute the fair market value of the Other Consideration contained therein by delivery of a written notice to HEP. Upon the delivery of such dispute notice to HEP, Sinclair HoldCo and HEP shall, during the ten (10) Business Days following the date of delivery of such dispute notice, negotiate in good faith to resolve the dispute. If Sinclair HoldCo and HEP cannot reach agreement as to the fair market value of the Other

5

Consideration during such period, Sinclair HoldCo and HEP shall refer such matter to a mutually agreed upon nationally recognized investment bank, or if Sinclair HoldCo and HEP are unable to mutually agree upon an investment bank, to an investment bank selected by the Houston Office of the American Arbitration Association. The investment bank’s determination of the fair market value of the Other Consideration shall be final and binding upon the Parties and the fee of the investment banking firm shall be split equally between HEP and Sinclair HoldCo.

(A) In the event that Sinclair HoldCo does not elect to dispute the fair market value of the Other Consideration set forth in the UNEV Pipeline Divestiture Notice, HEP shall reduce the number of HEP Common Units to be issued to Sinclair HoldCo at the Closing pursuant to Section 2.1(b) by the Divestiture Units.

(B) In the event that Sinclair HoldCo elects to dispute the fair market value of the Other Consideration set forth in the UNEV Pipeline Divestiture Notice, then, no later than five (5) Business Days following the final determination of the fair market value of the Other Consideration, Sinclair HoldCo shall forfeit to HEP a number of HEP Common Units equal to the Divestiture Units. For purposes of this Section 2.1(f):

(iii) “Sinclair Divestiture Portion” means an amount equal to (A)(I) $380 million multiplied by (II) the percentage (up to 50.1%) of the aggregate equity interest in UNEV Pipeline LLC sold as set forth in the definitive agreements contemplating the UNEV Pipeline Divestiture Action, minus (B) the UNEV Pipeline Divestiture Proceeds, multiplied by (C) 0.5;

(iv) “Divestiture Units” means a number of whole HEP Common Units (rounded to the nearest unit) equal to the (A) Sinclair Divestiture Portion, divided by (B) $22.50;

(v) “UNEV Pipeline Divestiture Proceeds” shall mean the base purchase price with respect to up to 50.1% of the aggregate equity interest in UNEV Pipeline LLC set forth in the definitive agreements contemplating the UNEV Pipeline Divestiture Action.

(g) Withholding. HEP and each of its Affiliates shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Agreement or any other Transaction Documents such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of local, state, federal, or foreign Tax Law; provided, however, HEP shall use reasonable best efforts to (i) notify Sinclair HoldCo of its intent to withhold any amounts under this Section 2.1(g) at least five (5) Business Days before Closing, (ii) provide Sinclair HoldCo with a reasonable opportunity to establish an exemption or other basis for reducing or eliminating such withholding tax and (iii) cooperate with Sinclair HoldCo to mitigate or reduce any such withholding taxes. To the extent that amounts are so deducted or withheld by HEP or such Affiliate and paid over to the applicable Governmental Authority, such deducted or withheld amounts shall be treated for all purposes of this Agreement or other applicable Transaction Document as having been paid to the Person in respect of which such deduction and withholding was made by HEP or such Affiliate.

Section 2.2 Closing Accounting Adjustment.

(a) As promptly as practicable, but no later than ninety (90) days after the Closing Date, HEP shall prepare and deliver to Sinclair HoldCo its calculation of the (i) Closing Working Capital, (ii) Closing Cash, (iii) Closing Indebtedness, and (iv) the resulting Closing Adjustment Amount (such calculation, the “Closing Accounting Statement”) and the work papers supporting such calculation. The Closing Accounting Statement shall be unaudited and prepared in accordance with the accounting principles set forth on Schedule 2.2(a) and in a format consistent with the illustrative calculation on Schedule 2.2(a), which assumes a Closing Date of December 31, 2020; provided, however, that the Closing Accounting Statement shall not take into account the Contemplated Transactions. From and after the Closing until the date on which the Final Closing Working Capital, Final Closing Cash, and Final Closing Indebtedness are finally determined in accordance with this Section 2.2, HEP shall not take any action with respect to the accounting books and records of the Company relating to the pre-closing period, or the items reflected thereon, on which the Closing Accounting Statement is to be based, that is inconsistent with the accounting principles set forth on Schedule 2.2(a). HEP and Sinclair HoldCo shall cooperate and assist in the preparation of the Closing Accounting Statement and the calculation of the items listed in the foregoing clauses (i) through (iv) and in the conduct of the review referred to in this Section 2.2, and HEP shall afford, and shall cause the Company and the Company Subsidiaries to afford, to Sinclair HoldCo and any accountants, counsel or financial advisors retained by Sinclair HoldCo, reasonable access to the books, personnel Representatives (including the Company’s accountants) and records of the Company and the Company Subsidiaries to the extent reasonably necessary for Sinclair HoldCo to review the Closing Accounting Statement; provided, that, any cooperation and assistance provided by HEP, the Company or any Company Subsidiaries shall be upon reasonable prior notice by Sinclair HoldCo and shall be during regular business hours and in a manner that does not interfere with the normal business or operations of HEP or its Affiliates.

(b) Sinclair HoldCo may, within 30 days after the Closing Accounting Statement has been received by Sinclair HoldCo, dispute any of the amounts reflected on the line items of the Closing Accounting Statement (each, a “Disputed Item”); provided, however, that in each case Sinclair HoldCo shall notify HEP in writing of each Disputed Item and specify in reasonable detail the amount in dispute and the basis therefor. To the extent Sinclair HoldCo does not notify HEP in writing that a certain line item of the Closing Accounting Statement is a Disputed Item within 30 days after the Closing Accounting Statement has been received by Sinclair HoldCo, such item shall become final and binding for the purposes of determining the (i) Final Closing Working Capital, (ii) Final Closing Cash, (iii) Final Closing Indebtedness, and (iv) the resulting Closing Adjustment Amount.

(c) If a notice of Disputed Item(s) shall be timely delivered pursuant to Section 2.2(b), then Sinclair HoldCo and HEP shall, during the 20 Business Days following the date of such delivery (the “Resolution Period”), negotiate in good faith to resolve the Disputed Item(s). If, during the Resolution Period, Sinclair HoldCo and HEP reach an agreement with respect to any or all Disputed Item(s), such agreement shall be evidenced in writing and the Closing Accounting Statement (as revised pursuant to such written agreement) shall become final and binding on the date of such agreement, with respect to each such agreed Disputed Item. If, during the Resolution Period, Sinclair HoldCo and HEP cannot reach agreement on a Disputed Item, then Sinclair HoldCo and HEP shall refer all remaining unresolved Disputed Items to Deloitte Touche Tohmatsu Limited (the “Independent Accountant”). If Deloitte Touche Tohmatsu Limited does not agree to serve as the Independent Accountant within 10 days after written request from Sinclair HoldCo and HEP to serve, then Sinclair HoldCo and HEP will mutually select and engage an alternative

7

independent nationally recognized accounting firm, or if Sinclair HoldCo and HEP are unable to agree upon such firm or such firm declines to serve as the Independent Accountant, then Sinclair HoldCo or HEP may request that the Houston office of the American Arbitration Association select the Independent Accountant, and Sinclair HoldCo and HEP will engage such Independent Accountant selected by the American Arbitration Association. Sinclair HoldCo and HEP shall cooperate with the Independent Accountant and promptly provide all documents and information requested by the Independent Accountant in connection with its determination with respect to the Disputed Item(s). The Independent Accountant shall review this Agreement and the Disputed Item(s) for the sole purposes of calculating the Disputed Item(s) and the resulting Closing Adjustment Amount, and in each case, in accordance with the accounting principles set forth on Schedule 2.2(a) and the terms of this Agreement, and shall make a determination, acting as an expert and not as an arbitrator, of each Disputed Item within 30 days after its engagement, which determination shall be made in accordance with the rules in this Section 2.2. With respect to each Disputed Item, the Independent Accountant shall select and adopt, without modification, only from the final offer of either Sinclair HoldCo or HEP in making its determination. The Independent Accountant shall deliver to Sinclair HoldCo and HEP, within such 30 day period, a report specifying (A) its final determination of the Closing Working Capital, Closing Cash, and Closing Indebtedness, (B) the resulting Closing Adjustment Amount, (C) its adjustments, if any, to the Closing Accounting Statement in connection with the items listed in the foregoing clauses (A) and (B), and (D) the calculations supporting such determinations and adjustments in the foregoing clauses (A), (B), and (C). Such report shall, absent manifest error, be final, conclusive and binding on the Parties. Each of the Closing Working Capital, Closing Cash, and Closing Indebtedness, as finally determined pursuant to this Section 2.2, is referred to herein as the “Final Closing Working Capital,” “Final Closing Cash,” and “Final Closing Indebtedness,” as applicable. The Independent Accountant shall determine the allocation of the cost of its review and report based on the inverse of the percentage its determination (before such allocation) bears to the total amount of the Disputed Items as originally submitted to the Independent Accountant. For example, should the Disputed Items amount to $1,000 and the Independent Accountant awards $600 in favor of Sinclair HoldCo’s position, sixty percent (60%) of the costs of its review would be borne by HEP and forty percent (40%) of the costs would be borne by Sinclair HoldCo. Any dispute arising under this Section 2.2 regarding the Independent Accountant’s determination of each Disputed Item, including enforcement of the determination by the Independent Accountant, must be resolved pursuant to Section 10.12. After the Closing Accounting Statement has become final and binding on the Parties in accordance with the terms of this Section 2.2, the following payments shall be made:

(i) If the Closing Adjustment Amount is positive, then HEP shall pay to Sinclair HoldCo, within three (3) Business Days after the determination of the Closing Adjustment Amount, by wire transfer of immediately available funds to the account or accounts designated in writing by Sinclair HoldCo, an amount of cash equal to the Closing Adjustment Amount.

(ii) If the Closing Adjustment Amount is negative, then Sinclair HoldCo shall pay to HEP, within three (3) Business Days after the determination of the Closing Adjustment Amount, by wire transfer of immediately available funds to the account or accounts designated in writing by HEP, an amount of cash equal to the absolute value of the Closing Adjustment Amount.

8

(iii) Upon payment of all of the amounts provided in this Section 2.2(c), none of the Parties may make or assert any claim under this Section 2.2 for any matter included in the Final Closing Working Capital, Final Closing Cash, or Final Closing Indebtedness or the resulting Closing Adjustment Amount.

(d) For U.S. federal income Tax purposes, any Closing Adjustment Amount paid by HEP to Sinclair HoldCo pursuant to Section 2.2(c)(i) and any Closing Adjustment Amount paid by Sinclair HoldCo to HEP pursuant to Section 2.2(c)(ii), respectively, will each be treated in a manner consistent with the Intended Tax Treatment, in each case except to the extent otherwise required pursuant to a “determination” that is final within the meaning of Section 1313(a) of the Code (or any similar provision of applicable state, local or non-U.S. Tax Law) or a change in applicable Law after the date hereof.

(e) Prior to the Closing, Sinclair HoldCo shall cause the applicable members of the Company Group to assign to Sinclair HoldCo or its designated Affiliate without recourse any account receivable that is individually in excess of $2,000,000, to the extent such account receivable will be excluded from Current Assets for purposes of this Section 2.2.

FURTHER AGREEMENTS

The Parties covenant and agree as follows:

Section 6.1 Efforts of the Parties.

(a) Subject to the terms and conditions of this Agreement, including Section 6.1(b) and Section 6.2, and the Business Combination Agreement in the case of the Business Combination, the Parties shall, as promptly as reasonably practicable, use reasonable best efforts to take, or cause to be taken, all action and do, or cause to be done, all things necessary under applicable Laws or otherwise proper and advisable to consummate and make effective the Contemplated Transactions and the Business Combination.

(b) The Parties shall give notices to and use reasonable best efforts to obtain any consent, authorization or approval of any private third party (other than any Governmental Authority) that may be or become necessary in connection with this Agreement or the Business Combination Agreement and the performance of its obligations pursuant to this Agreement or the Business Combination Agreement.

46

Section 6.2 Regulatory Clearance.

(a) Each of the Parties shall, and shall cause each of its respective Affiliates to, (i) file any required Notification and Report Forms with the DOJ and FTC pursuant to the HSR Act within fifteen (15) Business Days after the date of this Agreement; (ii) supply as promptly as reasonably practicable any additional information and documentary material that may be requested pursuant to the HSR Act or any other Antitrust Law; and (iii) use its reasonable best efforts to take or cause to be taken all other actions necessary, proper or advisable consistent with this Section 6.2 to satisfy the Closing condition in Section 7.1(b) as soon as practicable, which reasonable best efforts shall include avoiding and eliminating any impediment under the HSR Act and any other Antitrust Law and refraining from taking actions that would reasonably be expected to delay the expiration or termination of the applicable waiting periods, or receipt of required authorizations, as applicable, under the HSR Act and any other Antitrust Law. Without limiting the foregoing, the Parties shall request and shall use reasonable best efforts to obtain expiration or early termination of the waiting period under the HSR Act in connection with the Contemplated Transactions and the Business Combination as soon as practicable. In the event of a Woods Cross Refinery Divestiture Action (as defined in the Business Combination Agreement), HEP shall transfer to HFC all of HEP’s rights, title and interest in and to the Woods Cross Refinery Assets (as defined in the Business Combination Agreement); provided, however, that under no circumstances shall HEP be required to transfer any of its rights, title or interest in the SLC Pipeline or the Frontier Aspen Pipeline.

(b) Notwithstanding anything to the contrary set forth in this Agreement, HEP shall not have any obligation to, and Sinclair HoldCo or the Company may not without HEP’s written consent: (i) agree or commit to sell, divest, hold separate, or otherwise dispose of any particular asset, properties, category, equity interest, portion or part of an asset or business of HEP, the Company or their respective Subsidiaries (a “Divestiture Action”); (ii) terminate, modify, or assign existing relationships, Contracts, or obligations of HEP, the Company or their respective Subsidiaries; (iii) change or modify any course of conduct regarding future operations of HEP, the Company or their respective Subsidiaries; or (iv) otherwise take or commit to take any other action that would limit the freedom of action of HEP with respect to, or their ability to retain, one or more of its respective operations, divisions, businesses, product lines, customers, assets or rights or interests, or their freedom of action with respect to the assets, properties, or businesses to be acquired as part of the Contemplated Transactions or the Business Combination, except as otherwise contemplated in the Business Combination Agreement; provided, however, if required to satisfy the closing conditions in Section 7.1(a) and Section 7.1(b) and cause the Closing to occur no later than the End Date, HEP shall agree to a Divestiture Action with respect to up to 50.1% of the aggregate equity interest in UNEV Pipeline LLC (a “UNEV Pipeline Divestiture Action”); provided, further, that HEP shall not be required to agree to or take any such UNEV Pipeline Divestiture Action that is not conditioned on, or that becomes effective prior to, the Closing. Anything in this Agreement notwithstanding, nothing in this Section 6.2 or otherwise in this Agreement shall require HEP to take or cause to be taken any Divestiture Action with respect to any asset, property, business or equity interest of HEP or any of its Subsidiaries. Notwithstanding anything in this Agreement to the contrary, HEP may at its sole discretion compel the Company to take or agree to any Divestiture Action so long as the effectiveness of such Divestiture Action is conditioned upon the Closing and does not become effective prior to the Closing.

(c) Each of the Parties shall, and shall cause each of its respective Representatives to, (i) promptly keep each other Party apprised of the status of any communications with, and any inquiries or requests for additional information from, the DOJ, FTC or any other Governmental Authority, and shall substantially comply with any such inquiry or request as promptly as

47

practicable; (ii) cooperate and consult with each other in connection with the making of all filings, notifications and any other material actions pursuant to this Section 6.2, including, subject to applicable Laws relating to the exchange of information, by permitting counsel for the other Party to review in advance, and consider in good faith the views of the other Party in connection with, any proposed written communication to any Governmental Authority and provide counsel for the other Party with copies of all filings and submissions made by such Party and all correspondence and other written communications between such Party (and its advisors) and any Governmental Authority and any other information supplied by such Party or its respective Representatives, as the case may be, to a Governmental Authority or received from such a Governmental Authority in connection with the Contemplated Transactions or the Business Combination; provided, however, that materials may be redacted before being provided to the other Party (A) to remove references concerning the valuation of the Company Group, (B) as necessary to comply with contractual arrangements and (C) as necessary to address reasonable privilege, competition or confidentiality concerns; (iii) furnish to the other Party, as promptly as practicable, such information and assistance as such other Party reasonably may request in connection with the preparation of any submissions to, or agency proceedings by, any Governmental Authority under the HSR Act or any other applicable Law; and (iv) not have any meeting, teleconference, videoconference or substantive oral or written conversation or discussion with any Governmental Authority in respect of any filing or proceeding contemplated by this Section 6.2 unless it consults with the other Party in advance and, to the extent permitted by such Governmental Authority, gives the other Party the opportunity to participate. Pursuant to the terms of this Section 6.2, each Party shall, and shall cause each of its respective Representatives to, cooperate and use its reasonable best efforts to assist in any defense by any other Party before any Governmental Authority reviewing the Contemplated Transactions or the Business Combination under the HSR Act or any other applicable competition or Antitrust Law, including by providing as promptly as practicable such information as may be requested by such Governmental Authority or such assistance as may be reasonably requested by the other Party in such defense. Without limiting HEP’s obligations described in this Section 6.2, HEP will control the ultimate strategy for securing approvals and expiration or termination of the relevant waiting period under the HSR Act, including any filings, submissions and communications with or to any Governmental Authority in connection therewith, and taking into account in good faith, acting reasonably, any comments of the Company or its Representatives relating to such strategy.

(d) Each of the Parties shall not extend, directly or indirectly, any such waiting period or enter into any agreement with a Governmental Authority to delay or not to consummate the Contemplated Transactions or the Business Combination on the Closing Date, except with the prior written consent of the other Party, which consent shall not be unreasonably withheld.

Section 6.3 Certain Tax Matters.

(a) Tax Returns.

(i) Sinclair HoldCo shall prepare or cause to be prepared each Tax Return of the Company or any Company Subsidiary for a Pre-Closing Tax Period that is required to be filed on or after the Closing Date (each, a “Pre-Closing Tax Return”). Each Pre-Closing Tax Return shall be prepared in a manner consistent with past practice except to the extent required by applicable Law. Not later than 30 days prior to the due date (including extensions) for filing each

48

such Pre-Closing Tax Return, Sinclair HoldCo shall deliver a draft of such Pre-Closing Tax Return, together with all supporting documentation and workpapers, to HEP for its review and comment. Sinclair HoldCo shall consider in good faith any comments received from HEP not less than 15 days prior to the due date (including extensions) for filing such Pre-Closing Tax Return. Not later than five (5) days prior to the due date for filing such Pre-Closing Tax Return, Sinclair HoldCo shall provide such revised Pre-Closing Tax Return to HEP (executed, as may be required, by any present or former authorized owners or officers of the Company) for filing by HEP with the appropriate Governmental Authority, and HEP shall cause such Pre-Closing Tax Return (as revised to incorporate HEP’s comments agreed to by Sinclair HoldCo) to be timely executed and filed and cause all Taxes shown as due thereon to be timely paid. Sinclair HoldCo shall pay to HEP the amount of any Pre-Closing Taxes with respect to such Pre-Closing Tax Return no later than five (5) Business Days prior to the due date for payment of Taxes with respect to such Pre-Closing Tax Return.

(ii) HEP shall prepare or cause to be prepared each Tax Return of the Company or any Company Subsidiary for a Straddle Period (each, a “Straddle Tax Return”). Each Straddle Tax Return shall be prepared in a manner consistent with past practice except to the extent required by applicable Law. Not later than 30 days prior to the due date (including extensions) for filing such Straddle Tax Return, HEP shall deliver a draft of such Straddle Tax Return, together with all supporting documentation and workpapers, to Sinclair HoldCo for its review and comment. HEP shall (A) consider in good faith any comments received from Sinclair HoldCo not less than 15 days prior to the due date (including extensions) for filing such Straddle Tax Return, (B) cause such Straddle Tax Return (as revised to incorporate Sinclair HoldCo’s comments agreed to by HEP) to be timely executed and filed and all Taxes shown as due thereon to be timely paid, and (C) provide a copy thereof to Sinclair HoldCo. Sinclair HoldCo shall pay to HEP the amount of any Pre-Closing Taxes with respect to such Straddle Tax Return no later than five (5) Business Days prior to the due date for payment of Taxes with respect to such Straddle Tax Return.

(iii) If, in accordance with this Section 6.3(a), the Parties are unable to agree on the finalization of a Pre-Closing Tax Return or Straddle Tax Return prior to the due date (including extensions) for filing such Pre-Closing Tax Return or Straddle Tax Return, then (i) Sinclair HoldCo shall file such Pre-Closing Tax Return or such Straddle Tax Return, as applicable, in accordance with, as applicable, Sinclair HoldCo’s position relating to such disputed items (with respect to a Pre-Closing Tax Return) or HEP’s position relating to such disputed items (with respect to a Straddle Tax Return), (ii) the disputed items shall be resolved by the Independent Accountant in accordance with the procedures set forth in Section 2.2(c), whose determination shall be final and binding on the Parties, and (iii) to the extent the Independent Accountant’s determination differs from the position taken on the previously filed Pre-Closing Tax Return or Straddle Tax Return, as applicable, HEP shall amend (and, if necessary, Sinclair HoldCo shall cooperate to amend) such Pre-Closing Tax Return or Straddle Tax Return, as applicable, as need be to reflect the determination of the Independent Accountant. All costs related to preparing and filing such amended Tax Return will be borne by HEP and Sinclair HoldCo in the same proportion as any fees related to the Independent Accountant are borne as set forth in Section 2.2(c).

(b) Transfer Taxes. The Parties do not expect that any excise, sales, use, stamp, transfer, documentary, filing, recordation or value added Taxes or other similar Taxes or fees (collectively, “Transfer Taxes”) will be incurred as a result of or with respect to the Sinclair

49

Contribution. In the event that any Transfer Taxes are due as a result of or with respect to the Sinclair Contribution, HEP shall be responsible for fifty percent (50%) of such Transfer Taxes and Sinclair HoldCo shall be responsible for fifty percent (50%) of such Transfer Taxes. The Party customarily responsible under applicable Law for filing any Tax Returns remitting such Transfer Taxes shall properly do so in a timely manner, and the non-filing Party agrees to remit to the filing Party, upon demand, an amount in cash equal to such non-filing Party’s allocable share under this Section 6.3(b) of the Transfer Taxes shown on such Tax Return. If required by applicable Law, HEP and Sinclair HoldCo or their respective Affiliates, as applicable, will join in the execution of any Tax Returns required to remit such Transfer Taxes. The Parties shall reasonably cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any Transfer Taxes.

(c) Cooperation on Tax Matters. The HEP Entities and Sinclair HoldCo shall cooperate fully as and to the extent reasonably requested by another Party in respect of Tax matters arising under this Agreement, including in the preparation, review, and filing of Tax Returns and in connection with any audit, investigation, litigation, or other Proceeding (including a refund request, an objection or an appeal) with respect to the Intended Tax Treatment or with respect to Taxes imposed on or with respect to the assets, operations or activities of a member of the Company Group for a Pre-Closing Tax Period or a Straddle Period (each a “Tax Proceeding”). Such cooperation will include the retention and (upon the other Party’s reasonable request) the timely provision of all documents, data and other information which may be relevant to any such Tax Return or Tax Proceeding until the expiration of any applicable limitation period (taking into account applicable extensions) under applicable Law with respect to such Taxes and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Any information obtained by a Party or its Affiliates from another Party or its Affiliates in connection with any Tax matters to which this Agreement applies shall be kept confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or claims for a refund or in conducting an audit or other proceeding, or as may otherwise be necessary to enforce the provisions of this Agreement.

(d) Tax Proceedings. Each Party shall notify the other Parties in writing within fifteen (15) days of receipt by the applicable Party or its Affiliates of written notice of any Tax Proceeding. Such notification shall specify in reasonable detail the subject matter of such Tax Proceeding and shall include a copy of the relevant portion of any correspondence received from the Governmental Authority, provided, that failure to comply with this provision shall not affect the HEP Indemnified Parties’ right to indemnification hereunder except to the extent such failure actually and materially prejudices Sinclair HoldCo. Notwithstanding anything to the contrary in this Agreement or any Transaction Document, as of the Closing:

(i) Sinclair HoldCo shall control, at its sole cost and expense, any Tax Proceeding of Sinclair HoldCo with respect to the Intended Tax Treatment; provided, however, that Sinclair HoldCo shall keep HEP reasonably informed with respect to the defense and progress of such Tax Proceeding. Sinclair HoldCo shall control, at its sole cost and expense, any Tax Proceeding of a member of the Company Group for a Pre-Closing Tax Period; provided, however, that (A) subject to the procedures of Section 9.3 of this Agreement, Sinclair HoldCo shall acknowledge in writing its obligation to indemnify the HEP Indemnified Parties in respect of such Tax Proceedings, (B) HEP shall, at HEP’s sole cost and expense, have the right to participate in

50

any such Tax Proceeding, (C) Sinclair HoldCo shall keep HEP reasonably informed with respect to the defense and progress of such Tax Proceeding, (D) Sinclair HoldCo shall reasonably consult with HEP before taking any material or significant action in connection with such Tax Proceeding and shall consider in good faith any comments received from HEP (which comments shall not be unreasonably withheld or delayed), (E) Sinclair HoldCo shall not settle, compromise, abandon or otherwise resolve any such Tax Proceeding without HEP’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, and (F) Sinclair HoldCo shall conduct the control of such Tax Proceeding diligently and in good faith.

(ii) HEP shall control, at its sole cost and expense, any Tax Proceeding of the HEP Entities with respect to the Intended Tax Treatment, provided, however, that HEP shall keep Sinclair HoldCo reasonably informed with respect to the defense and progress of such Tax Proceeding. HEP shall control, at its sole cost and expense, any Tax Proceeding of a member of the Company Group for a Straddle Period; provided, however, that (A) Sinclair HoldCo, shall, at Sinclair HoldCo’s sole cost and expense, have the right to participate in any such Tax Proceeding, (B) HEP shall keep Sinclair HoldCo reasonably informed with respect to the defense and progress of such Tax Proceeding, (C) HEP shall reasonably consult with Sinclair HoldCo before taking any material or significant action in connection with such Tax Proceeding and shall consider in good faith any comments received from Sinclair HoldCo (which comments shall not be unreasonably withheld or delayed), (D) HEP shall not settle, compromise, abandon or otherwise resolve any such Tax Proceeding without Sinclair HoldCo’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, and (E) HEP shall conduct the control of such Tax Proceeding diligently and in good faith. For the avoidance of doubt, to the extent the procedures of this Section 6.3(d) conflict with the procedures set forth in Section 9.3(b), this Section 6.3(d) shall control over the procedures under Section 9.3(b) with respect to any Tax Proceedings or other matters governed by this Section 6.3(d).

(e) Post-Closing Actions Affecting Pre-Closing Tax Periods or Straddle Periods. HEP covenants that, following the Closing, the HEP Entities will not, and will not cause or permit the Company Group to, (i) make or change any Income Tax or other Tax election or take any position on any Income Tax Return or other Tax Return, in each case with respect to the Company Group, for (or that would have retroactive effect to) any Pre-Closing Tax Period or the pre-Closing portion of any Straddle Period, (ii) file, amend or otherwise modify any Income Tax Return or other Tax Return of the Company for any Pre-Closing Tax Period or Straddle Period or (iii) enter into an agreement to extend the statute of limitations with respect to any Income Tax Return or other Tax Return of the Company for any Pre-Closing Tax Period or any Straddle Period, except in each case to the extent that (A) such action is required by applicable Law, (B) Sinclair HoldCo has provided its prior written consent to any such action, which consent shall not be unreasonably withheld, conditioned or delayed, (C) such action is in accordance with the other provisions of this Section 6.3, (D) such action is directed or facilitated by Sinclair HoldCo in accordance with the provisions of this Section 6.3 (including, but not limited to, Section 6.3(d)), or (E) HEP agrees to waive any indemnity claim under Section 9.2 of this Agreement with respect to such action and HEP agrees to indemnify Sinclair HoldCo and each ultimate beneficial owner of Sinclair HoldCo for any additional Liability for Taxes owed by it as a result of or attributable to such action.

51

(f) Tax Treatment of the Sinclair Contribution.

(i) For U.S. federal (and where applicable, state and local) income Tax purposes, the relevant Parties intend to treat the Sinclair Contribution as a contribution of property to HEP under Section 721(a) of the Code, subject to Section 707(a)(2)(B) of the Code and its implementing Treasury Regulations; provided that (A) each liability of the Company or the Company Subsidiaries or to which their assets are subject assumed as part of the Sinclair Contribution shall be treated as a “qualified liability” (within the meaning of Treasury Regulation Section 1.707-5(a)(6)) to the extent (x) Sinclair HoldCo has provided a statement to HEP, in a form acceptable to HEP and inclusive of any necessary supporting documentation, representing that it has received advice from a nationally recognized accounting or law firm, that such liability should be treated as a “qualified liability” (within the meaning of Treasury Regulation Section 1.707-5(a)(6)), and (y) HEP has received concurring advice from a nationally recognized accounting or law firm to that obtained by Sinclair HoldCo in accordance with clause (x), and (B) the Parties agree to use reasonable best efforts to determine whether any transfers of cash (or deemed transfers of cash) to Sinclair HoldCo (which, for the avoidance of doubt, the Parties agree includes any amount of liabilities other than “qualified liabilities” (within the meaning of Treasury Regulation Section 1.707-5(a)(6)) assumed as part of the Sinclair Contribution) shall be treated as a reimbursement of preformation capital expenditures within the meaning of Treasury Regulation Section 1.707-4(d), and if the Parties are unable to agree, such determination shall be made by the Independent Accountant in accordance with the procedures set forth in Section 2.2(c) (the “Intended Tax Treatment”).

(ii) Each of HEP, the Company, and Sinclair HoldCo will, and will cause its Subsidiaries and Affiliates to, (A) use its reasonable best efforts to cause the Sinclair Contribution to qualify for the Intended Tax Treatment, and (B) not knowingly take any action (whether or not otherwise permitted under this Agreement), or cause any action to be taken, which action would prevent or impede, or that could reasonably be expected to prevent or impede, the Sinclair Contribution from qualifying for the Intended Tax Treatment. Each of the Parties will notify the other Party promptly after becoming aware of any reason to believe that the Sinclair Contribution likely will not qualify for the Intended Tax Treatment.

(iii) Each of the Parties has reviewed with its own Tax advisor the U.S. federal, state and local Tax consequences of the Contemplated Transactions. Each Party understands that it will be responsible for its own Tax liability, if any, that may arise as a result of the Contemplated Transactions.

(iv) The Parties shall prepare and file all Tax Returns consistent with the Intended Tax Treatment, and, except to the extent otherwise required by a final “determination” within the meaning of Section 1313(a) of the Code, take no Tax position inconsistent with the Intended Tax Treatment.

(g) Tax Sharing Agreements. All Tax sharing agreements or similar agreements with respect to or involving any of the Company and the Company Subsidiaries shall be terminated as of the Closing Date and, after the Closing Date, none of the Company nor any Company Subsidiaries shall be bound thereby or have any liability thereunder.

(h) Proration of Straddle Period Taxes. For all purposes of this Agreement, in order to apportion appropriately any Taxes relating to a Straddle Period, in the case of Taxes that are payable with respect to any Straddle Period, the portion of any such Taxes that are attributable to the portion of a Straddle Period ending on the Closing Date shall be:

52

(i) in the case of any Taxes that are imposed on a periodic basis with respect to the assets or capital of the Company or any Company Subsidiary, deemed to be the amount of such Taxes for the entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period) multiplied by a fraction, the numerator of which is the number of calendar days in the portion of such Straddle Period ending on and including the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period; and

(ii) in the case of all other Taxes (including, for the avoidance of doubt, Excise Taxes), deemed equal to the amount that would be payable if the relevant Straddle Period ended on and included the Closing Date (as if there was an interim period closing of the books); provided, that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the portion of the Straddle Period ending on and including the Closing Date and the portion of the Straddle Period beginning after the Closing Date in proportion to the number of calendar days in each portion of such Straddle Period.

(i) Tax Refunds. The amount of any refunds of Taxes (including, for the avoidance of doubt, any refunds of Excise Taxes) of the Company and any Company Subsidiary for any Pre-Closing Tax Period shall be for the account of Sinclair HoldCo. The amount of any refunds of Taxes (including, for the avoidance of doubt, any refunds of Excise Taxes) of the Company and any Company Subsidiary for any Tax period beginning after the Closing Date shall be for the account of HEP. The amount of any refund of Taxes of the Company and any Company Subsidiary for any Straddle Period shall be equitably apportioned between HEP and Sinclair HoldCo in accordance with the principles set forth in Section 6.3(h). Notwithstanding the foregoing, Sinclair HoldCo shall not be entitled to any refund of Taxes pursuant to this Section 6.3(i) (A) attributable to the carryback of any Tax attribute from a Tax period (or portion thereof) beginning after the Closing Date to any Pre-Closing Tax Period or to the pre-Closing portion of any Straddle Period, or (B) included in the calculation of the Closing Adjustment Amount (or any item included therein). Each Party shall forward, and shall cause its Affiliates to forward, to the Party entitled to receive a refund of Tax pursuant to this Section 6.3(i) the amount of such refund within 30 days after such refund is received, net of any third-party costs or expenses (including Taxes) incurred by such Party or its Affiliates in procuring such refund; provided, that, notwithstanding anything in this Agreement to the contrary, in the event that any refund of Taxes is subsequently determined by any Governmental Authority to be less than the amount paid to such Party pursuant to this Section 6.3(i), such Party shall promptly return any such disallowed amounts (plus any interest in respect of such disallowed amount owed to a Governmental Authority) to the payor Party.

(j) Purchase Price Allocation. Within 120 days following the Closing Date, HEP shall prepare an estimated allocation of the Base Cash Consideration and all items properly treated as consideration for U.S. federal income Tax purposes (including capitalized costs and any liabilities treated as assumed) among the assets of the Company and the Company Subsidiaries in accordance with Section 1060 of the Code and the Treasury Regulations thereunder (and any similar provision of state, local, or non-U.S. Law, as appropriate) and deliver a schedule setting forth such allocation

53

(the “Allocation Schedule”) to Sinclair HoldCo. Sinclair HoldCo shall cooperate fully as and to the extent reasonably requested by HEP in respect of the preparation of the Allocation Schedule, including timely and properly preparing, executing, filing and delivering all such documents, forms and other information as HEP may reasonably request in connection therewith. Sinclair HoldCo shall have thirty (30) days from the delivery of the Allocation Schedule by HEP to contest the allocations set forth in the Allocation Schedule by notifying HEP in writing and providing a detailed written explanation of the items contested by Sinclair HoldCo (including relevant workpapers). If Sinclair HoldCo timely contests the Allocation Schedule, HEP and Sinclair HoldCo shall cooperate in good faith to promptly resolve any disputes with respect to the Allocation Schedule. If the Parties are unable to resolve any disputed item in the Allocation Schedule within thirty (30) days after HEP’s receipt of Sinclair HoldCo’s contested items (or such other time period mutually agreed to by the Parties), such contest shall be determined by the Independent Accountant in accordance with the procedures set forth in Section 2.2(c). The Allocation Schedule, as agreed to or finally determined by the Independent Accountant pursuant to the procedures in Section 2.2(c) (or, if Sinclair HoldCo does not timely contest the Allocation Schedule pursuant to this Section 6.3(j), as delivered by HEP pursuant to this Section 6.3(j)) (the “Final Allocation”) shall be final and shall be binding upon the Parties, HEP and Sinclair HoldCo shall use commercially reasonable efforts to update the Final Allocation in accordance with Section 1060 of the Code following any adjustment to the Sinclair Contribution Consideration pursuant to this Agreement, and HEP and Sinclair HoldCo shall, and shall cause their Affiliates to, report consistently with the Final Allocation, as adjusted, on all Tax Returns, and none of the Parties, nor any of their respective Affiliates, shall take any position on any Tax Return or otherwise with respect to Taxes which is inconsistent with the Final Allocation except to the extent otherwise required following a “determination” that is final within the meaning of Section 1313(a) of the Code (or any similar provision of applicable state, local, or non-U.S. Tax Law); provided, however, that neither Party shall be unreasonably impeded in its ability and discretion to negotiate, compromise and/or settle any Tax proceeding in connection with such Final Allocation.

Section 6.4 Further Assurances.

(a) From time to time at the request of the other Party, (x) prior to the Closing, HEP, on the one hand, and the Company and Sinclair HoldCo, on the other hand, and, (y) from and after the Closing, HEP and the Company, on the one hand, and Sinclair HoldCo, on the other hand, shall, without further consideration, execute and deliver such documents, instruments and assurances of transfer, conveyance, assignment and assumption, and take such further actions as may reasonably be necessary or desirable to carry out and effectuate the provisions of this Agreement (including the Company Reorganization), including, if and to the extent it is determined at any time after the Closing (a) that legal title to, beneficial ownership of, or other interest in all or part of (i) any asset of the Retained Business (including any asset used to provide services contemplated by the Transition Services Agreement) is held by any member of the Company Group, or (ii) any asset of the Midstream Business (excluding any asset used to provide services contemplated by the Transition Services Agreement) is held by Sinclair HoldCo or any of its Affiliates, or (b) (i) that any member of the Company Group assumed or retained, as applicable, any of the Retained Liabilities, or (ii) that Sinclair HoldCo or any of its Affiliates assumed or retained, as applicable, any of the Assumed Liabilities, in each case taking such actions as HEP or Sinclair HoldCo may reasonably direct in order to carry out the purposes set forth herein, without further consideration.

54

(b) Sinclair HoldCo and HEP shall negotiate in good faith and use commercially reasonable efforts to prepare and finalize a mutually agreeable “Exhibit A” to the Transition Services Agreement within six (6) months from the date of this Agreement.

Section 6.5 Access, Information and Documents.

(a) From and after the date hereof until the Closing, on reasonable advance notice from HEP, the Company shall, and shall cause each other member of the Company Group to, to the extent permitted by Law, permit HEP and its Representatives to have reasonable access, during regular business hours, to the assets (including the Sinclair Real Property), Facilities, personnel, Contracts, books and records and other documents and data relating to the Company Group; provided, however, that (i) no such access (or related activities or investigations) shall unreasonably interfere with any of the Company Group’s normal business operations, (ii) no such access (or related activities or investigations) shall be permitted on any portion of Sinclair Leased Real Property if such access (or related activities or investigations) would violate the terms of the applicable Sinclair Lease and (iii) access to personnel of the Company Group shall be subject to the prior approval of the Company as to the scope and duration of such access and the specific personnel involved, such approval not to be unreasonably withheld, conditioned or delayed. HEP shall bear the risk of injury to itself, any of its Affiliates, and their respective Representatives conducting any investigation or inspection pursuant to this Section 6.5, except to the extent such injury is caused by the gross negligence or willful misconduct of the Company Group or any of its personnel. The Company shall have the right to have one or more Representatives accompany HEP and its Representatives at all times during HEP’s and its Representatives’ on-site inspection of the assets, Facilities, personnel, Contracts, books and records and other documents and data relating to the Company Group.

(b) Notwithstanding anything to the contrary in this Agreement, nothing in this Agreement shall be construed to permit HEP or its Representatives to (i) have access to any files, records, Contracts or documents of the Company Group relating to (A) particular terms of any Contracts to the extent that disclosure of such terms, based upon the advice of outside counsel of the Company, could risk violating any antitrust or similar applicable Law or (B) information that is subject to confidentiality restrictions or attorney-client or other legal privilege, provided, however, that in the event such information is not provided, Sinclair HoldCo shall provide HEP with notice thereof and a reasonable description of the nature of such withheld information, (ii) subject to Section 6.2(c), have access to competitively sensitive information, including proprietary technology or processes or trade or industrial secrets or (iii) conduct any invasive inspections, investigations, tests or assessments of any portion of Sinclair Real Property or any invasive environmental tests, including any sampling or other invasive investigation of the soil, water, air, soil gas, surface water, groundwater, building materials or other environmental media at any Sinclair Real Property or access the proprietary network of the Company Group (provided, however, that nothing herein shall prohibit licensed surveyors engaged by HEP from accessing the Sinclair Real Property for purposes of preparing ALTA/NSPS surveys thereof, which surveys Sinclair HoldCo hereby expressly permits). HEP shall ensure that the access permitted pursuant to Section 6.5 will be solely in connection with the Contemplated Transactions. During such access, HEP and its Representatives shall comply with the applicable policies and procedures of the Company Group that have been provided to HEP and its Representatives prior to or in connection with such access. If, at any time, the Company reasonably believes that any

55

Representative of HEP has not complied with such policies and procedures, then the Company may immediately terminate such Representative’s access. HEP shall indemnify and hold harmless Sinclair HoldCo, the Company and their respective Affiliates from and against all Damages that arise out of or result from any of HEP’s and its Representatives’ site visits and access to any property of the Company Group, except to the extent arising from or relating to the gross negligence or willful misconduct of the Company Group. Promptly upon completion of any such access, HEP shall repair at its sole expense any Damages caused by such access.

(c) From and after the date hereof until the Closing, if Sinclair HoldCo believes in good faith that a HEP Material Adverse Effect has occurred or would reasonably be expected to occur, then on reasonable advance notice from Sinclair HoldCo, HEP shall, and shall cause each other HEP Entity to, to the extent permitted by Law and solely to the extent reasonably necessary for Sinclair HoldCo to evaluate whether a HEP Material Adverse Effect has occurred or would reasonably be expected to occur, permit Sinclair HoldCo and its Representatives to have reasonable access, during regular business hours, to the assets and properties (including the HEP Real Property) of the applicable HEP Entities in respect of which Sinclair HoldCo reasonably believes a HEP Material Adverse Effect has occurred or would reasonably be expected to occur; provided, however, that (i) no such access (or related activities or investigations) shall unreasonably interfere with any HEP Entity’s normal business operations, (ii) no such access (or related activities or investigations) shall be permitted on any portion of HEP Leased Real Property if such access (or related activities or investigations) would violate the terms of the applicable HEP Lease, and (iii) no such access shall be permitted with respect to competitively sensitive information, including proprietary technology or processes or trade or industrial secrets. Sinclair HoldCo shall bear the risk of injury to itself, any of its Affiliates, and their respective Representatives conducting any investigation or inspection pursuant to this Section 6.5, except to the extent such injury is caused by the gross negligence or willful misconduct of the HEP Entities or any of their personnel. HEP shall have the right to have one or more Representatives accompany Sinclair HoldCo and its Representatives at all times during Sinclair HoldCo and its Representatives’ on-site inspection of the assets or properties relating to the HEP Entities.

(d) No Party, nor any of its Affiliates, or their respective Representatives, shall, prior to the Closing, contact any known customer, vendor, supplier, lessor, lessee, party to an easement, or employee of the other Party with respect to the Contemplated Transactions, except where it has received the prior written consent of such other Party. Notwithstanding the foregoing, but subject to the applicable terms of the Confidentiality Agreement, this Section 6.5(d) shall not limit or otherwise restrict any Party, its Affiliates, or their respective Representatives from contacting or having business dealings with any such Person with whom any such Party or its Affiliates has or may have business dealings, so long as such contact or business dealings do not relate to the other Party’s business dealings with such Person or with respect to any aspect of the Contemplated Transactions.

(e) Each of Sinclair HoldCo and HEP acknowledges and agrees that the Confidentiality Agreement remains in full force and effect and, in addition, shall keep confidential, in accordance with the provisions of the Confidentiality Agreement, information provided to such Party pursuant to this Section 6.5. If this Agreement is, for any reason, terminated prior to the Closing, the Confidentiality Agreement and the provisions of this Section 6.5(e) shall nonetheless continue in full force and effect in accordance with the terms thereof.

(vi) take any action (or omit to take any action) if such action (or omission) would reasonably be expected to cause any of the conditions set forth in Article 7 not being satisfied by the End Date; or

(vii) agree to take any of the foregoing actions.

(c) In furtherance of, and without limiting the Parties’ obligations in this Section 6.6, Sinclair HoldCo shall, from and after the date hereof until the Closing, cause each member of the Company Group to use commercially reasonable efforts to take the actions set forth on Schedule 6.6(c).

Section 6.7 280G Cooperation.

(a) As soon as reasonably practicable following the execution of this Agreement but in any case no later than thirty (30) Business Days prior to the Closing Date, Sinclair HoldCo shall provide to HEP and HEP’s advisors, for their reasonable review and comment, its preliminary analysis (“Section 280G Analysis”) regarding the application of Section 280G of the Code and the regulations promulgated thereunder (“Section 280G”) in connection with the Contemplated Transactions (either alone or in combination with any other additional or subsequent event, including a termination of employment) to each Person who is determined by Sinclair HoldCo to be a “disqualified individual” within the meaning of Section 280G (each such Person, a “280G Disqualified Individual”). No later than fifteen (15) Business Days prior to the Closing Date, Sinclair HoldCo shall provide to HEP and HEP’s advisors, for their reasonable review and comment, its final Section 280G Analysis.

(b) Sinclair HoldCo shall (i) use commercially reasonable efforts to obtain, prior to the solicitation of the 280G Approval (as defined below), a waiver agreement from each 280G Disqualified Individual who could otherwise receive or retain or have the right or entitlement to receive or retain any “parachute payment” within the meaning of Section 280G, waiving any and all rights or entitlements to receive or retain any such payment to the extent that the value thereof (determined in accordance with Section 280G) equals or exceeds three times such Person’s “base amount” (within the meaning of and determined in accordance with Section 280G), unless the 280G Approval is obtained (each such waiver agreement, a “280G Waiver”); provided that a

60

“disqualified individual’s” election not to execute a 280G Waiver despite Sinclair HoldCo’s commercially reasonable efforts to obtain such waiver will not, by itself, constitute a breach of this Section 6.7, and (ii) following the execution of the 280G Waivers by any applicable “disqualified individuals,” solicit and take commercially reasonable efforts to obtain any necessary stockholder approval of any such payments or benefits so waived in a manner that is intended to satisfy all the requirements of Section 280G(b)(5)(B) of the Code and the regulations promulgated thereunder (the “280G Approval”); provided that the stockholders’ failure to approve such waived payments and benefits pursuant to the 280G Approval despite Sinclair HoldCo’s commercially reasonable efforts to obtain such 280G Approval will not, by itself, constitute a breach of this Section 6.7.

(c) No later than ten (10) Business Days prior to soliciting the 280G Waivers as provided above, Sinclair HoldCo shall provide to HEP and HEP’s advisors drafts of the stockholder approval materials (including Section 280G Waivers, disclosure and consent documentation) for their reasonable review and comment (which such comments shall be considered in good faith by Sinclair HoldCo for incorporation into such documentation).

Section 6.8 Takeover Laws.

Each of HEP, the Company and Sinclair HoldCo, acting in its capacity as sole shareholder of the Company, shall (a) take no action to cause any Takeover Law to become applicable to this Agreement or the Contemplated Transactions and (b) if any Takeover Law is or becomes applicable to this Agreement or the Contemplated Transactions, take all reasonable action necessary to cause the Contemplated Transactions to be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such Takeover Law with respect to this Agreement and the Contemplated Transactions.

Section 6.9 Notification of Certain Matters.

Prior to the Closing, each of HEP and the Company shall, to the extent permitted by applicable Law, promptly notify the other Party of (a) any notice or other communication received from any Person alleging that the consent of such Person is or may be required in connection with the Contemplated Transactions, (b) any Action commenced or, to such Party’s knowledge, threatened against, that challenges the validity or legality of the Contemplated Transactions or seeks damages in connection therewith or (c) (i) any change, condition or event that results in any of the conditions in Sections 7.2(a) or 7.3(a) not being met or (ii) the failure of such Party to comply with or satisfy in any material respect any covenant, condition or agreement (including any condition set forth in Article 7) to be complied with or satisfied hereunder; provided, however, that no such notification shall affect any of the representations, warranties, covenants, rights or remedies, or the conditions to the obligations of, the Parties.

Section 6.10 Indemnification and Insurance.

(a) Following the Closing, HEP agrees (and shall cause the Company and each Company Subsidiary to agree) that all rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the Closing, whether asserted or claimed prior to, at or after the Closing (including in respect of any matters arising in connection with this Agreement and the Contemplated Transactions), in favor of a D&O Person as provided in the

61

organizational documents of any member of the Company Group (in each case as in effect on the date hereof) shall survive the Closing and shall continue in full force and effect in accordance with their respective terms for a period of six (6) years from the Closing Date, it being the intent of the Parties that all such D&O Persons shall continue to be entitled to such exculpation, indemnification and advancement of expenses to the fullest extent permitted by applicable Law; provided, however, that all rights to indemnification in respect of any pending or asserted Action or any claim made within such period shall continue until the disposition of such Action or resolution of such claim.

(b) In the event that HEP, the Company or any of their respective successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving company or entity of such consolidation or merger or (ii) transfers or conveys fifty percent (50%) or more of its properties and other assets to any Person (including by liquidation, dissolution or assignment for the benefit of creditors or similar action), then, and in each such case, HEP or the Company, as the case may be, shall cause proper provision to be made so that the applicable successors and assigns or transferees expressly assume the obligations set forth in this Section 6.10.

(c) The obligations of HEP under this Section 6.10 shall not be terminated, amended or modified in any manner so as to adversely affect any D&O Person to whom this Section 6.10 applies without the consent of such D&O Person. The provisions of this Section 6.10 are intended to be for the benefit of, and shall be enforceable by, each D&O Person, his or her heirs and his or her executors, administrators and personal representatives, each of whom is an intended third party beneficiary of this Section 6.10, and are in addition to, and not in substitution of, any other rights, including rights to indemnification or contribution that any such Person may have by Contract or otherwise. The provisions of this Section 6.10 shall survive the Closing.

Section 6.11 Termination of Affiliate Obligations.

On or before the Closing Date, except as set forth on Schedule 6.11, and except for this Agreement and the Transaction Documents, all Sinclair Affiliate Contracts shall be settled and terminated in full and there shall be no Liability or obligations of the Company or any Company Subsidiary surviving such termination, such termination being effective as of the completion of the Closing.

Section 6.12 Certain NYSE Matters.

HEP shall use its reasonable best efforts to cause the HEP Common Units comprising the Sinclair Partnership Interest Consideration as provided for in Article 2, to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Closing.

Section 6.13 Use of Certain Names.

Except as disclosed on Schedule 6.13, Sinclair HoldCo agrees that, within one hundred eighty (180) days after the Closing Date, except as otherwise permitted in a separate written agreement signed by HEP, Sinclair HoldCo shall, and shall cause its Affiliates to, cease using the Trademarks listed on Company Disclosure Schedule 4.11(a) (the “Company Marks”), including removing, or causing to be removed, all such Company Marks from any public-facing physical or digital products, facilities, signage or materials (including on any website or social media account).

62

Notwithstanding anything to the contrary provided in this Section 6.13, Sinclair HoldCo and its Affiliates may use (a) the Company Marks (i) in a neutral, non-trademark manner (e.g., to describe the historical relationship of the Parties), or (ii) to the extent required by Law, and (b) the names of any member of the Company Group to the extent necessary for any public filings or press releases made by Sinclair HoldCo or its Affiliates, but solely to the extent related to the Contemplated Transactions.

Section 6.14 Other Insurance Efforts.

(a) With respect to the Insurance Policies maintained by the Company Group, Sinclair HoldCo or its Affiliates at or prior to the Closing, the members of the Company Group may make claims under any such applicable Insurance Policy following the Closing with respect to claims made or occurrences prior to the Closing to the extent such claims or occurrences apply to the Midstream Business, including in the event that, after the date of this Agreement but prior to or on the Closing Date, any portion of the assets of the Midstream Business is damaged or destroyed by fire, explosion, hurricane, flood, storm, weather events, earthquake, act of nature, civil unrest or similar disorder, terrorist acts, war or any other hostilities or other casualty (each, a “Casualty Event”). Sinclair HoldCo shall (and shall cause its Affiliates to) use reasonable best efforts to assist the Company Group in asserting any such claims and making the benefits of any such Insurance Policies available to the Company Group. In furtherance of the foregoing, Sinclair HoldCo shall provide reasonable assistance to HEP and the Company Group in connection with HEP’s or the Company Group’s investigation of the facts and circumstances underlying any potential claims, and the Company Group’s assertion of any such claims under any such Insurance Policies, which shall include, for the avoidance of doubt, providing information and documentation reasonably requested by HEP or the Company Group and their respective Representatives, including access to facilities and personnel of Sinclair HoldCo, to the extent such information and documentation reasonably relates to any such potential claim, as soon as reasonably practicable, and in any event, with sufficient time to permit the Company Group to comply with the terms of the applicable Insurance Policy.

(b) In the event that a Casualty Event occurs prior to the Closing, Sinclair HoldCo and its Affiliates shall, and shall cause the members of the Company Group to, make all claims under the applicable Insurance Policies with respect to such Casualty Event and use, and cause the members of the Company Group to use, commercially reasonable efforts to restore the affected assets to the condition prior to such Casualty Event during the period prior to the Closing, in each case, to the extent reasonably practicable to do so prior to the Closing, as determined by Sinclair HoldCo in good faith, and without prejudice to any claim by Sinclair HoldCo or any of its Affiliates under the Insurance Policies. Following the Closing, HEP shall, and shall cause the members of the Company Group to, use commercially reasonable efforts to continue the pursuit of any such claims.

(i) If, prior to the Closing, Sinclair HoldCo and its Affiliates, including the members of the Company Group, actually receive proceeds for property damages coverage under a property Insurance Policy with respect to a Casualty Event that occurred prior to the Closing, all such proceeds shall be retained by or contributed to the applicable member of the Company Group that suffered such Casualty Event. In such case, (i) the amount of such proceeds equal to the excess of the reasonable documented out-of-pocket costs and expenses of Sinclair HoldCo or the

63

Company Group incurred in connection with pursuing and collecting such proceeds and restoring the affected assets prior to the Closing over the amounts of the applicable deductible(s) with respect to the applicable Casualty Event (such amount, the “Sinclair Casualty Expenses”) shall be included in the calculation of Closing Cash pursuant to Section 2.1(d) and Section 2.2(a), and (ii) all other amounts of such proceeds shall not be included in the calculation of Closing Cash pursuant to Section 2.1(d) and Section 2.2(a).

(ii) If, following the Closing, HEP or the Company Group actually receives proceeds for property damages coverage under a property Insurance Policy with respect to a Casualty Event that occurred prior to the Closing that are in excess of the reasonable documented out-of-pocket costs and expenses of HEP or the Company Group in pursuing and collecting such proceeds, HEP shall pay or shall cause the Company Group to pay to Sinclair HoldCo an amount equal to the Sinclair Casualty Expenses, and, for the avoidance of doubt, Sinclair HoldCo or the Company Group shall retain any amounts (and the right to receive any amounts) of such proceeds in excess thereof. If the Sinclair Casualty Expenses are less than the applicable deductible(s) with respect to the applicable Casualty Event, an amount equal to the difference between such deductible(s) and the Sinclair Casualty Expenses shall be included as a Current Liability for purposes of Section 2.1(d) and Section 2.2(a). By way of example only, if the applicable deductible(s) for a Casualty Event is $10,000,000 in the aggregate and the Sinclair Casualty Expenses are $12,000,000, the related Current Liability would be $0, but, if the Sinclair Casualty Expenses are $6,000,000, the related Current Liability would be $4,000,000.

(iii) If, following the Closing, HEP or the Company Group actually receives proceeds from an Insurance Policy covering business interruption with respect to a matter that occurred prior to the Closing, HEP shall, and shall cause the Company Group to, pay to Sinclair HoldCo the portion of the amount actually received that relates to the period prior to the Closing and that is in excess of the reasonable documented out-of-pocket costs and expenses of HEP or the Company Group in pursuing and collecting such proceeds.

(c) Other than as set forth in Section 6.14(a), HEP acknowledges that all insurance policies maintained by Sinclair HoldCo or its Affiliates shall be terminated as of Closing with respect to the Company Group, and HEP shall be solely responsible for obtaining insurance for the Company Group from and after the Closing.

(d) With respect to any insurance policies maintained by the Company Group at or prior to the Closing, Sinclair HoldCo or its Affiliates may make claims under an applicable policy following the Closing with respect to claims made or occurrences prior to the Closing, to the extent such claims or occurrences apply to the Retained Business, the Retained Liabilities or the Legacy Assets. HEP shall (and shall cause its Affiliates to) use reasonable best efforts to assist Sinclair HoldCo and its Affiliates in asserting any such claims and making the benefits of any such insurance policies available to Sinclair HoldCo and its Affiliates. In furtherance of the foregoing, HEP shall provide reasonable assistance to Sinclair HoldCo and its Affiliates in connection with Sinclair HoldCo’s or any of its Affiliate’s investigation of the facts and circumstances underlying any potential claims, and Sinclair HoldCo’s or its Affiliate’s assertion of any such claims under any such policies, which shall include, for the avoidance of doubt, providing information and documentation reasonably requested by Sinclair HoldCo or its Affiliates and its and their respective Representatives, including access to facilities and personnel of the Company Group members, to the extent such information and documentation reasonably relates to any such potential claim, as soon as reasonably practicable, and in any event, with sufficient time to permit Sinclair HoldCo and its Affiliates to comply with the terms of the applicable policy.

64

Section 6.15 Books and Records.

(a) HEP shall preserve and keep any books and records of the Company Group that relate to any period beginning on or before the Closing Date for a period of six (6) years after the Closing Date (or longer for Tax records if required by Section 6.3) and shall reasonably cooperate with Sinclair HoldCo and its Affiliates to make available to Sinclair HoldCo and its Affiliates, during normal business hours and in such a manner as to not unreasonably interfere with the business of HEP, the Company Group or their respective Affiliates, such books and records as are reasonably necessary in connection with any dispute, litigation or defense of any indemnification claim, or in order to enable Sinclair HoldCo or its Affiliates to comply with its obligations under this Agreement or to perform the Contemplated Transactions. Following such six (6) year period (or such longer period with respect to Tax records as may be required in Section 6.3), HEP may retain or destroy such books and records; provided, however, that HEP shall notify Sinclair HoldCo prior to any such destruction and, if requested by Sinclair HoldCo no more than fifteen (15) Business Days after such notification, shall deliver such books and records to Sinclair HoldCo, at Sinclair HoldCo’s sole expense, prior to such destruction. Notwithstanding anything in this Agreement to the contrary, Sinclair HoldCo and its Affiliates may retain copies of the books and records and minute books of the Company relating to the period on or before the Closing Date.

(b) Sinclair HoldCo shall preserve and keep any books and records of the Company Group that are not delivered to HEP or its Affiliates in connection with the Closing or prior to the termination of the Transition Services Agreement and relate to any period beginning on or before the Closing Date for a period of six (6) years after the Closing Date (or longer for Tax records if required by Section 6.3) and shall reasonably cooperate with HEP and its Affiliates to make available to HEP and its Affiliates, during normal business hours and in such a manner as to not unreasonably interfere with the business of Sinclair HoldCo or its Affiliates, such books and records as are reasonably necessary in connection with any dispute, litigation or defense of any indemnification claim, or in order to enable HEP or its Affiliates to comply with its obligations under this Agreement or to perform the Contemplated Transactions. Following such six (6) year period (or such longer period with respect to Tax records as may be required in Section 6.3), Sinclair HoldCo may retain or destroy such books and records; provided, however, that Sinclair HoldCo shall notify HEP prior to any such destruction and, if requested by HEP no more than fifteen (15) Business Days after such notification, shall deliver such books and records to HEP, at HEP’s sole expense, prior to such destruction.

Section 6.16 Wrong Pockets.

The Parties acknowledge that all assets (and rights to future payments related thereto) with respect to the Midstream Business are intended to be transferred to HEP pursuant to the Sinclair Contribution, except as otherwise provided herein. If, following the Closing, Sinclair HoldCo or any of its Affiliates receives or collects any funds relating to the Midstream Business or any asset of any member of the Company Group, on behalf of HEP, except as otherwise provided herein, Sinclair HoldCo shall, or shall cause its Affiliates to, promptly remit such funds to HEP. The

65

Parties acknowledge that all assets (and rights to future payments related thereto) with respect to the Retained Business are intended to be retained by Sinclair HoldCo or any Affiliates thereof. If, following the Closing, HEP or any of its Affiliates (including the Company Group) receives or collects any funds relating to the Retained Business on behalf of Sinclair HoldCo, HEP shall, or shall cause its Affiliates to, promptly remit such funds to Sinclair HoldCo.

Prior to the Closing, Sinclair HoldCo shall cause Company to convert into a limited liability company duly organized, validly existing and in good standing under the Laws of the state of Wyoming (the “Company Conversion”). The Company Conversion shall be completed pursuant to documents, agreements and certificates that are in form and substance reasonably acceptable to HEP.

Additionally, and notwithstanding anything in this Section 6.19 or elsewhere in this Agreement to the contrary, neither the issuance of, nor the commitment, agreement, or willingness on the part of the Title Insurance Company to issue, the HEP Title Policies (or any of them), regardless of form, shall in any event constitute a condition precedent to the obligation of HEP to consummate the Contemplated Transactions.

Section 6.20 Credit Support Arrangements.

(a) Prior to the Closing, HEP shall use commercially reasonable efforts to deliver to the applicable beneficiary or counterparty replacement or substitute guaranties, letters of credit, bonds, security deposits, and other surety obligations and evidence of financial capacity, in each case acceptable to the relevant beneficiary or counterparty, in substitution and replacement of those credit support arrangements relating to the Midstream Business set forth in Schedule 6.20 (the “Credit Support Arrangements”), and HEP and Sinclair HoldCo shall cooperate and use commercially reasonable efforts to secure the release as of the Closing of Sinclair HoldCo and its Affiliates from the obligations relating to the Credit Support Arrangements.

HEP, on the one hand, and Sinclair HoldCo, on the other, acknowledges and agrees that, from and after the Closing, except for Fraud and except as expressly provided in Section 9.2, such Party and its Affiliates (and any Person claiming under, or in the name or right of, such Party or any of its Affiliates), will not have any right of indemnification, contribution, subrogation or reimbursement from, or any other remedy against, the other Party, its Affiliates or its or their respective Representatives in respect of the representations, warranties, covenants or other agreements contained in this Agreement or any certificate delivered in respect hereof or any schedule (including the Company Disclosure Schedules and the HEP Disclosure Schedules, as applicable), certificate or other similar instrument delivered pursuant to this Agreement, regardless of applicable Law or the legal theory under which such remedy may be sought to be asserted, whether in contract or in tort or otherwise, or whether at law or in equity.

Section 9.2 Indemnification.

(a) Effective as of the Closing, HEP hereby indemnifies Sinclair HoldCo, its Affiliates and its and their respective Representatives (together, in each case, with their respective successors and assigns, the “Sinclair HoldCo Indemnified Parties”) against, and agrees to hold them harmless from, any and all Damages arising out of, resulting from or related to:

(i) any breach or inaccuracy of any of the HEP Fundamental Representations;

(ii) HEP’s breach of or failure to perform any of its covenants or agreements contained in this Agreement, to the extent they contemplate performance following the Closing; and

(iii) any Assumed Liabilities (including claims arising out of, resulting from or related to the failure of HEP to in due course pay or discharge any Assumed Liability).

(b) Effective as of the Closing, Sinclair HoldCo hereby indemnifies HEP, its Affiliates and its Representatives (together, in each case, with their respective successors and assigns, the “HEP Indemnified Parties”) against, and agrees to hold them harmless from, any and all Damages arising out of, resulting from or related to:

(i) any breach or inaccuracy of any of the Company Fundamental Representations;

75

(ii) Sinclair HoldCo’s or the Company’s breach or failure to perform any of its covenants or agreements contained in this Agreement, to the extent they contemplate performance following the Closing;

(iii) any Indebtedness of the Company Group as of the Closing, other than Indebtedness referred to in clauses (d), (g) and (i) (with respect to Indebtedness referred to in clauses (d) and (g) of the definition thereof) of the definition thereof;

(iv) any Retained Liabilities (including claims arising out of, resulting from or related to Sinclair HoldCo’s failure to in due course pay or discharge any Retained Liability); and

(v) Pre-Closing Taxes.

(c) Any indemnification payments hereunder shall be treated as adjustments to the Sinclair Contribution Consideration for all Tax purposes, except to the extent otherwise required by Law.

(d) No claim for indemnification (or otherwise) in connection with a representation, warranty, covenant or agreement shall be brought or made after the applicable date set forth in Section 9.1, except for particular claims that have been asserted in accordance with the terms of this Agreement by any Indemnified Party against any Indemnifying Party prior to or on the applicable date set forth in Section 9.1. For the avoidance of doubt, this Section 9.2(d) shall not apply to claims under Section 9.2(b)(v) with respect to Pre-Closing Taxes, and any Pre-Closing Tax claims under Section 9.2(b)(v) shall survive until thirty (30) days following the expiration of the applicable statute of limitations (as the same may be extended).

(e) Notwithstanding anything in this Article 9 to the contrary, the HEP Indemnified Parties will not be entitled to indemnification for any Damages pursuant to Section 9.2(b)(v) (except to the extent such Damages arise out of, result from or relate to (i) Income Taxes or (ii) Property Taxes, in which case this Section 9.2(e) shall not apply) unless and until the aggregate of all such indemnifiable Damages exceeds an aggregate amount of $1,000,000.

(f) Notwithstanding anything to the contrary in this Section 9.2, the Sinclair HoldCo Indemnified Parties, on the one hand, and the HEP Indemnified Parties, on the other hand, shall not be entitled to indemnification under this Article 9 for any Damages to the extent the amount of such Damages was taken into account in the calculation of the Closing Adjustment Amount.

Section 9.3 Procedures.

(a) If any Sinclair HoldCo Indemnified Party seeks indemnification pursuant to Section 9.2(a), or if any HEP Indemnified Party seeks indemnification pursuant to Section 9.2(b), the Person seeking indemnification (the “Indemnified Party”) shall give written notice to the Party from whom such indemnification is sought (the “Indemnifying Party”) promptly (and in any event within fifteen (15) days) after the Indemnified Party (or, if the Indemnified Party is not a natural person, any Representative of the Indemnified Party) becomes aware of the facts giving rise to such claim for indemnification (an “Indemnified Claim”) specifying in reasonable detail the factual basis of the Indemnified Claim, stating the amount of Damages (or if not known, a good faith estimate of the amount of Damages) and the method of computation thereof, containing a

76

reference to the provision of this Agreement in respect of which such Indemnified Claim arises and a copy of any papers theretofore served on or delivered to the Indemnified Party and demanding indemnification therefor. The failure of an Indemnified Party to provide notice in accordance with this Section 9.3(a), or any delay in providing such notice, shall not limit the Indemnified Party’s rights or constitute a waiver of the Indemnified Party’s claims to indemnification pursuant to Section 9.2, except to the extent that any such failure or delay in giving notice causes the amounts paid or to be paid by the Indemnifying Party to be greater than they otherwise would have been or otherwise results in prejudice to the Indemnifying Party. Notwithstanding anything to the contrary contained in this Agreement, HEP shall deliver notice of any Indemnified Claim on behalf of any HEP Indemnified Party and Sinclair HoldCo shall deliver notice of any Indemnified Claim on behalf of any Sinclair HoldCo Indemnified Party. For the avoidance of doubt, no HEP Indemnified Party (other than HEP) and no Sinclair HoldCo Indemnified Party (other than Sinclair HoldCo) shall be entitled to bring an indemnification claim hereunder, it being understood that HEP may bring, but shall not be required to bring, any indemnification claim on behalf of any HEP Indemnified Party and Sinclair HoldCo may bring, but shall not be required to bring, any indemnification claim on behalf of any Sinclair HoldCo Indemnified Party.

(b) The Indemnifying Party will have the right, upon written notice delivered to the Indemnified Party within thirty (30) days of receipt of written notice of such Indemnified Claim, to assume the defense and control of any Third Party Claim (so long as prior to assuming the defense of same, the Indemnifying Party acknowledges its obligation to indemnify the Indemnified Party in writing), including the appointment and selection of counsel on behalf of the Indemnified Party so long as such counsel is reasonably acceptable to the Indemnified Party; provided, however, if the Indemnifying Party declines or fails to assume the defense of such Third Party Claim pursuant to this Section 9.3(b), then any Damages relating to such Indemnified Claim will include the reasonable fees and expenses (including reasonable attorneys’ fees and expenses) incurred by the Indemnified Party with respect thereto. Notwithstanding anything to the contrary in this Section 9.3(b), the Indemnified Party will control such indemnification claim (i) to the extent that the object of such Third Party Claim is to obtain an injunction, restraining order, declaratory relief or other material non-monetary relief against the Indemnified Party, (ii) if the named parties to any such Proceeding (including any impleaded parties) include both the Indemnified Party and the Indemnifying Party and the former shall have been advised in writing by counsel (with a copy to the Indemnifying Party) that there are one or more legal or equitable defenses available to it that are different from or additional to those available to Indemnifying Party, (iii) if the Indemnifying Party fails to provide reasonable assurance to the Indemnified Party of its financial capacity to defend the Third Party Claim and provide indemnification with respect to such Third Party Claim, (iv) if the Third Party Claim arises in connection with any criminal Proceeding against the Indemnified Party, (v) if the Third Party Claim, if adversely determined, would materially and adversely affect it or its Affiliates other than as a result of monetary Damages for which it would be entitled to indemnification under this Agreement (including by being reasonably likely to establish a precedent or custom that would be materially adverse to the Indemnified Party, whether or not monetary Damages are also asserted in connection with such claim), or (vi) an actual or readily apparent conflict of interest exists between the Indemnifying Party and the Indemnified Party with respect to the Third Party Claim that precludes effective joint representation; provided, that, in each case the Indemnifying Party will have reasonable information and consultation rights in connection therewith and the Indemnified Party not shall

77

settle such Third Party Claim without the Indemnifying Party’s prior consent, such consent not to be unreasonably withheld, conditioned or delayed, unless (A) such settlement includes an unconditional release from all Damages with respect to the Third Party Claim in favor of the Indemnified Party or (B) the Indemnified Party stipulates in writing that there are no Damages for which it is entitled to indemnification under this Article 9. Whether the Indemnifying Party or the Indemnified Party is defending and controlling any such Third Party Claim, it shall select counsel, contractors, experts and consultants of recognized standing and competence, shall take reasonable steps necessary in the investigation, defense or settlement thereof, and shall diligently and promptly pursue the resolution thereof. The Indemnified Party shall, and shall cause each of its Affiliates and Representatives to, cooperate with the Indemnifying Party in connection with any Third Party Claim. Once the Indemnifying Party has duly assumed the defense of a Third Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense and to employ separate counsel of its choosing at its sole cost and expense. If the Indemnifying Party assumes the defense of any such Third Party Claim but fails to diligently prosecute such Third Party Claim, the Indemnified Party may assume control of such defense and in the event it is finally determined that the Third Party Claim was a matter for which the Indemnifying Party is required to provide indemnification under the terms of this Section 9.3, the Indemnifying Party will bear the reasonable costs and expenses of such defense (including reasonable attorneys’ fees and expenses).

(c) Notwithstanding anything to the contrary in this Agreement, the Indemnifying Party will not be permitted to settle, compromise, take any corrective or remedial action or enter into an agreed judgment or consent decree, in each case, (i) that does not unconditionally release the Indemnified Party from all Liabilities and obligations with respect to such Third Party Claim, (ii) that imposes injunctive or other equitable relief against the Indemnified Party, (iii) that contains any admission or statement admitting or suggesting any wrongdoing or Liability on behalf of the Indemnified Party, or (iv) under which the Indemnified Party would be required to pay any portion of any monetary Damages arising as a result of the Third Party Claim, in each case without the Indemnified Party’s prior written consent.

(d) If an Indemnifying Party makes any payment on an Indemnified Claim, the Indemnifying Party shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnified Party to any insurance benefits or other claims or benefits of the Indemnified Party with respect to such claim.
