2.3 Indemnification Procedures.

(a) The Indemnified Party agrees that within a reasonable period of time after it becomes aware of facts giving rise to a claim for indemnification under this Article II, it will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim.

(b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article II, including the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such claim or any matter or any issues relating thereto; provided, however, that no such settlement for only the payment of money shall be entered into without the consent of the Indemnified Party unless it includes a full release of the Indemnified Party from such claim; provided, further, that no such settlement containing any form of injunctive or similar relief shall be entered into without the prior written consent of the Indemnified Party, which consent shall not be unreasonably delayed or withheld.

(c) The Indemnified Party agrees to cooperate in good faith and in a commercially reasonable manner with the Indemnifying Party with respect to all aspects of the defense of and pursuit of any counterclaims relating to any claims covered by the indemnification under this Article II, including the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense and counterclaims (provided, that the Indemnified Party has an opportunity to review the use of its name and does not reasonably object to such use), the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense and counterclaims, the making available to the Indemnifying Party of any employees of the Indemnified Party and the granting to the Indemnifying Party of reasonable access rights to the properties and facilities of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records and other information furnished by the Indemnified Party pursuant to this Section 2.3. The obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence shall not be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims and pursuit of any counterclaims with respect to any claims covered by the indemnification set forth in this Article II; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense and counterclaims. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense or counterclaim, but the Indemnifying Party shall have the right to retain sole control over such defense and counterclaims so long as the Indemnified Party is still seeking indemnification hereunder.

8

(d) In determining the amount of any loss, cost, damage or expense for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the Indemnified Party as a result of such claim and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons.

2.4 Limitations Regarding Indemnification.

(a) HEP shall not be obligated to indemnify, defend and hold harmless any Group Member under this Agreement until such time as the total aggregate amount of Losses incurred by the Partnership Group for such Losses exceeds $500,000 (the “Deductible”), at which time HEP shall be obligated to indemnify the Partnership Group for the amount of such Losses in excess of the Deductible.

(b) The Partnership Group shall not be obligated to indemnify, defend and hold harmless any HEP Group Member under Section 2.2 of this Agreement until such time as the total aggregate amount of Losses incurred by the HEP Group for such Losses exceeds the Deductible, at which time the Partnership Group shall be obligated to indemnify the HEP Group for the amount of such Losses in excess of the Deductible.

(c) For the avoidance of doubt, (i) there is no monetary cap on the amount of indemnity coverage provided by any Indemnifying Party under this Article II and (ii) the Partnership Group’s indemnification obligation under this Agreement shall be reduced on a dollar for dollar basis pro rata relative to HEP’s direct or indirect ownership interest in a Group Member that owns or leases or otherwise controls the Assets with respect to which an indemnification obligation for Losses exists.

(d) The indemnities set forth in Section 2.1(a), Section 2.1(b), Section 2.1(c), Section 2.1(d), Section 2.1(e) and Section 2.1(f) shall terminate on the third anniversary of the Closing Date. The indemnities set forth in Section 2.1(g) shall terminate on the fourth anniversary of the Closing Date. The indemnities set forth in Section 2.2 shall survive the Closing without time limit, to the fullest extent permitted by law. Notwithstanding the foregoing, there shall be no termination of any bona fide claim asserted pursuant to the indemnities in Section 2.1 prior to the date of termination for such indemnity.

(e) NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, TO THE FULLEST EXTENT PERMITTED BY LAW, IN NO EVENT SHALL ANY PARTY’S INDEMNIFICATION OBLIGATION HEREUNDER COVER OR INCLUDE CONSEQUENTIAL, INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, SPECIAL OR SIMILAR DAMAGES OR LOST PROFITS (INCLUDING ANY DIMINUTION IN VALUE OF ANY PARTY’S RESPECTIVE INVESTMENT IN THE PARTNERSHIP) SUFFERED, DIRECTLY OR INDIRECTLY, BY ANY OTHER PARTY ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT, EXCEPT AS A REIMBURSEMENT FOR ANY SUCH DAMAGES AS ARE PAID TO A GOVERNMENTAL AUTHORITY OR OTHER THIRD PARTY.

9

2.5 Express Negligence. TO THE FULLEST EXTENT PERMITTED BY LAW, THE INDEMNIFICATION, RELEASE, ASSUMPTION AND WAIVER PROVISIONS PROVIDED FOR IN THIS AGREEMENT SHALL BE APPLICABLE WHETHER OR NOT THE LIABILITIES IN QUESTION ARISE AS A RESULT OF THE STRICT LIABILITY OR NEGLIGENCE (JOINT, SEVERAL, ACTIVE, PASSIVE, SOLE OR CONCURRENT) OF OR BY ANY INDEMNIFIED PARTY. THE PARTIES ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS.

2.6 Exclusive Remedy. Notwithstanding anything to the contrary contained in this Agreement, from and after the Closing Date, to the fullest extent permitted by law, Section 2.1 and Section 2.2 contain the Parties’ exclusive remedy against each other with respect to breaches of the covenants of the Parties set forth in Article II. Except for (a) the remedies contained in Section 2.1 and Section 2.2, (b) any other remedies available to the Parties at law or in equity for breaches of provisions of this Agreement other than Article II and (c) the remedies available at law or in equity in connection with any other document delivered by a Party in connection with the transactions contemplated hereby (including pursuant to the Contribution Agreement), from and after the Closing Date, to the fullest extent permitted by law, each of the Parties releases, remises and forever discharges the other and its Affiliates and all such Persons’ equity holders, partners, members, officers, directors, employees, agents, advisors and representatives from any and all claims for Losses available at law or in equity, known or unknown, which such Parties might now or subsequently may have, based on, relating to or arising out of this Agreement or the transactions contemplated hereby.

ARTICLE III

SERVICES; REIMBURSEMENT

3.1 General and Administrative Services.

(a) HEP agrees to provide, and agrees to cause its Affiliates, including HEP Services, to provide, to the General Partner, for the Partnership Group’s benefit, the general and administrative services that have been traditionally provided in connection with the ownership and operation of the Assets, which consist of the services set forth on Schedule B (the “General and Administrative Services”).

(b) Absent the written agreement of the Parties to the contrary, the Parties agree that the General and Administrative Services will be received by the General Partner, for the benefit of the Partnership Group, at the General Partner’s principal place of business.

(c) The Parties acknowledge that the costs and expenses of the General and Administrative Services will be allocated among the Group Members (which, for the avoidance of doubt, includes OpCo and each Subsidiary of OpCo) in good faith using a reasonable allocation methodology as determined by HEP.

3.2 Administrative Fee.

(a) As consideration for HEP’s and its Affiliates’ provision of the General and Administrative Services, the Partnership Group will pay to HEP an annual fee that will reflect

10

the costs incurred by HEP and its Affiliates in providing such General and Administrative Services (other than those costs for which HEP and its Affiliates are entitled to reimbursement pursuant to Section 3.3), as determined in good faith by HEP in accordance with Schedule B (the “Administrative Fee”). The Parties acknowledge and agree that it is the intent of the Parties that the General and Administrative Services be provided based on an arm’s-length standard and that the Administrative Fee is intended to reflect such standard. For the avoidance of doubt, the Parties further acknowledge and agree that the Administrative Fee will cover the fully burdened cost of the General and Administrative Services provided by HEP and its Affiliates to the Partnership Group, as well as any third-party costs actually incurred by HEP and its Affiliates on behalf of the Partnership Group in providing such General and Administrative Services (other than those costs for which HEP and its Affiliates are entitled to reimbursement pursuant to Section 3.3), including the following:

(i) the compensation and employee benefits (other than unit-based compensation) of employees of HEP or its Affiliates, including HEP Services (and any employment, payroll or similar taxes related thereto), to the extent, but only to the extent, such employees perform General and Administrative Services for the Partnership Group’s benefit. With respect to employees that do not devote all of their business time to the Partnership Group, such compensation and employee benefits (and any withholding or payroll taxes related thereto) are intended to be allocated to the Partnership Group based on the annual weighted average of time spent and number of employees devoting services to the Partnership Group or pursuant to such other reasonable allocation methodology as HEP may determine;

(ii) any expenses incurred or payments made by HEP or its Affiliates on behalf of the Partnership Group for insurance coverage with respect to the Assets or the business of the Partnership Group; and

(iii) all sales, use, excise, value added or similar taxes, if any, that may be applicable from time to time with respect to the General and Administrative Services provided by HEP and its Affiliates to the Partnership Group pursuant to Section 3.1.

(b) The Parties acknowledge and agree that the Administrative Fee may change each calendar year or upon the occurrence of a material contribution, acquisition or disposition to or by the Partnership Group, in each case, as determined by HEP in good faith, to accurately reflect the degree and extent of the General and Administrative Services provided to the Partnership Group by HEP, or to accurately reflect any change in the cost of providing General and Administrative Services to the Partnership Group due to changes in any law, rule or regulation applicable to HEP and its Affiliates or the Partnership Group, including any interpretation of such laws, rules or regulations.

(c) The Administrative Fee shall be invoiced and paid as follows:

(i) Within 20 days following the end of each month during the term of this Agreement, the HEP Group will submit to the Partnership Group an invoice of the amounts due for such month for the Administrative Fee.

11

(ii) The Partnership Group will pay the Administrative Fee within 10 days after the receipt of the invoice therefor. The Partnership Group shall not offset any amounts owing to it by HEP or any of its Affiliates against the Administrative Fee payable hereunder.

3.3 Reimbursement of General and Administrative Expenses. In addition to the Administrative Fee payable under Section 3.2, the Partnership Group will reimburse HEP and its Affiliates on a monthly basis for any additional out-of-pocket costs and expenses actually incurred by HEP and its Affiliates in providing the General and Administrative Services, as well as any other out-of-pocket expenses incurred on behalf of the Partnership Group, including any employment, payroll or similar taxes paid by HEP and its Affiliates in connection with any long-term incentive plan (or similar compensation plan) of the General Partner or the Partnership Group. The HEP Group shall invoice the Partnership Group for reimbursable costs and expenses within three months of incurrence and each invoice will contain reasonably satisfactory support of such amounts and such other supporting detail as the General Partner may reasonably require.

ARTICLE IV

RIGHT OF FIRST REFUSAL

4.1 Right of First Refusal to Purchase Certain Assets.

(a) HEP hereby grants to the Partnership a right of first refusal for a period of seven years from the Closing Date on any proposed Transfer (other than a grant of a security interest to a bona fide third-party lender or a Transfer to another HEP Group Member) of a portion or all of (i) HEP’s [●]% limited partner interest in OpCo or (ii) HEP’s interest in those certain assets set forth on Schedule D (collectively, the “ROFR Assets”). The Parties acknowledge and agree that nothing in this Article IV shall prevent or restrict the Transfer of the capital stock, equity or ownership interests or other securities of the General Partner or the Partnership.

(b) The Parties acknowledge that all potential Transfers of ROFR Assets pursuant to this Article IV are subject to obtaining any and all required written consents of Governmental Authorities and other third parties and to the terms of all existing agreements in respect of the ROFR Assets; provided, however, that HEP represents and warrants that, to its knowledge after reasonable investigation, there are no terms in such agreements that would materially impair the rights granted to the Partnership pursuant to this Article IV with respect to any ROFR Asset.

(c) The Partnership shall have the right, in its sole discretion, to assign its rights under this Article IV to any Group Member.

4.2 Procedures for Transfer of ROFR Assets.

(a) In the event HEP proposes to Transfer any of the ROFR Assets (other than a grant of a security interest to a bona fide third-party lender or a Transfer to another HEP Group Member) pursuant to a bona fide third-party offer (an “Acquisition Proposal”), then HEP shall, prior to entering into any such Acquisition Proposal, first give notice in writing to the Partnership (a “Disposition Notice”) of HEP’s intention to enter into such Acquisition Proposal. The Disposition Notice shall include any material terms, conditions and details as would be necessary for the Partnership to determine whether to exercise its right of first refusal with respect to the

12

Acquisition Proposal, which terms, conditions and details shall at a minimum include: the name and address of the prospective acquiror (the “Proposed Transferee”), the ROFR Assets subject to the Acquisition Proposal (the “Sale Assets”), the purchase price offered by such Proposed Transferee (the “Offer Price”), reasonable detail concerning any non-cash portion of the proposed consideration, if any, to allow the Partnership to reasonably determine the fair market value of such non-cash consideration, HEP’s estimate of the fair market value of any non-cash consideration and all other material terms and conditions of the Acquisition Proposal that are then known to HEP. To the extent the Proposed Transferee’s offer consists of consideration other than cash (or in addition to cash), the Offer Price shall be deemed equal to the amount of any such cash plus the fair market value of such non-cash consideration. In the event the Partnership and HEP are able to agree on the fair market value of any non-cash consideration or if the consideration consists solely of cash, the Partnership will provide written notice of its decision regarding the exercise of its right of first refusal to purchase the Sale Assets (the “ROFR Response”) to HEP within 60 days of its receipt of the Disposition Notice (the “First ROFR Acceptance Deadline”). In the event the Partnership and HEP are unable to agree on the fair market value of any non-cash consideration prior to the First ROFR Acceptance Deadline, the Partnership shall indicate its desire to determine the fair market value of such non-cash consideration pursuant to the procedures outlined in the remainder of this Section 4.2(a) in a ROFR Response delivered prior to the First ROFR Acceptance Deadline. If no ROFR Response is delivered by the Partnership prior to the First ROFR Acceptance Deadline, then the Partnership shall be deemed to have waived its right of first refusal with respect to such Sale Asset, except to the extent reinstated as provided in Section 4.2(d). In the event (i) the Partnership’s determination of the fair market value of any non-cash consideration described in the Disposition Notice is less than the fair market value of such consideration as determined by HEP in the Disposition Notice and (ii) the Partnership and HEP are unable to mutually agree upon the fair market value of such non-cash consideration within 60 days after the Partnership notifies HEP of its determination thereof, HEP and the Partnership will engage a mutually agreed upon, nationally recognized investment banking firm or other mutually acceptable qualified appraiser to determine the fair market value of the non-cash consideration. The investment banking firm or appraiser will determine the fair market value of the non-cash consideration within 30 days of its engagement and furnish the Partnership and HEP with its determination. The fees of the investment banking firm or appraiser will be split equally between the Partnership and HEP. Once the investment banking firm or appraiser has submitted its determination of the fair market value of the non-cash consideration, the Partnership will provide a ROFR Response to HEP within 30 days after the investment banking firm or appraiser has submitted its determination (the “Second ROFR Acceptance Deadline”). If no ROFR Response is delivered by the Partnership prior to the Second ROFR Acceptance Deadline, then the Partnership shall be deemed to have waived its right of first refusal with respect to such Sale Asset, except to the extent reinstated as provided in Section 4.2(d).

(b) If the Partnership elects in a ROFR Response delivered prior to the applicable ROFR Acceptance Deadline to exercise its right of first refusal with respect to a Sale Asset, within 60 days of the delivery of the ROFR Response, such ROFR Response shall be deemed to have been accepted by HEP and HEP shall enter into an agreement with the Partnership providing for the consummation of the Acquisition Proposal upon the terms set forth in the ROFR Response. Unless otherwise agreed between the Partnership and HEP, the terms of the purchase and sale agreement will include the following:

13

(i) The Partnership will agree to deliver the Offer Price in cash (unless the Partnership and HEP agree that such consideration will be paid, in whole or in part, in equity securities of the Partnership, an interest-bearing promissory note, or any combination thereof);

(ii) HEP will represent that it has title to the Sale Asset and, if applicable, that such title is sufficient to operate the Sale Asset in accordance with its intended and historical use, subject to all recorded matters and all physical conditions in existence on the closing date for the purchase of the applicable Sale Asset, plus any other such matters as the Partnership may approve. If the Partnership desires to obtain any title insurance with respect to the Sale Asset, the full cost and expense of obtaining the same (including the cost of title examination, document duplication and policy premium) shall be borne by the Partnership;

(iii) HEP will grant to the Partnership the right, exercisable at the Partnership’s risk and expense prior to the delivery of the ROFR Response, to make such surveys, tests and inspections of the Sale Asset as the Partnership may deem desirable, so long as such surveys, tests or inspections do not damage the Sale Asset or interfere with the activities of HEP;

(iv) The Partnership will have the right to terminate its obligation to purchase the Sale Asset under this Article IV if the results of any title examination, survey, test or inspection under Section 4.2(b)(ii) or 4.2(b)(iii) above are, in the reasonable opinion of the Partnership, unsatisfactory;

(v) the closing date for the purchase of the Sale Asset shall occur no later than 180 days following receipt by HEP of the ROFR Response pursuant to Section 4.2(a);

(vi) HEP and the Partnership shall use commercially reasonable efforts to do or cause to be done all things that may be reasonably necessary or advisable to effectuate the consummation of any transactions contemplated by this Section 4.2(b), including causing their respective Affiliates to execute, deliver and perform all documents, notices, amendments, certificates, instruments and consents required in connection therewith; and

(vii) neither the Partnership nor HEP shall have any obligation to sell or buy the Sale Assets if any of the consents referred to in Section 4.1(b) have not been obtained.

(c) The Partnership and HEP shall cooperate in good faith in obtaining all necessary governmental and other third party approvals, waivers and consents required for the closing. Any such closing shall be delayed, to the extent required, until the third business day following the expiration of any required waiting periods under the HSR Act; provided, however, that such delay shall not exceed 60 days following the 180 days referred to in Section 4.2(b)(v) (the “ROFR Governmental Approval Deadline”) and, if governmental approvals and waiting periods shall not have been obtained or expired, as the case may be, by such ROFR Governmental Approval Deadline, then the Partnership shall be deemed to have waived its right of first refusal with respect to the Sale Assets described in the Disposition Notice and thereafter HEP shall be free to consummate the Transfer to the Proposed Transferee, subject to Section 4.2(d)(ii).

14

(d) If the Transfer to the Proposed Transferee (i) in the case of a Transfer other than a Transfer permitted under Section 4.2(c), is not consummated in accordance with the terms of the Acquisition Proposal within the later of (A) 180 days after the applicable ROFR Acceptance Deadline and (B) three business days after the satisfaction of all governmental approval or filing requirements, if any, or (ii) in the case of a Transfer permitted under Section 4.2(c), is not consummated within the later of (A) 60 days after the ROFR Governmental Approval Deadline and (B) three business days after the satisfaction of all governmental approval or filing requirements, if any, then in each case the Acquisition Proposal shall be deemed to lapse, and HEP may not Transfer any of the Sale Assets described in the Disposition Notice without complying again with the provisions of this Article IV if and to the extent then applicable.

The Receiving Party shall disclose only that portion of the Disclosing Party’s Confidential Information that it is required or obligated to disclose and, to the fullest extent permitted by law, shall cooperate with the Disclosing Party in allowing the Disclosing Party to seek such protective order or other relief.
