This Agreement is made and entered into as of the Date of Grant set forth in the Notice of Grant of Phantom Units (“Notice of Grant”) by and between Holly Logistic Services, L.L.C. (the “Company”), and you.

WHEREAS, the Company, as part of your compensation for services to the Company and Holly Energy Partners, L.P. (the “Partnership”) and in order to induce you to materially contribute to the success of the Company and the Partnership, agrees to grant you this phantom unit award;

WHEREAS, the Company adopted the Holly Energy Partners, L.P. Long-Term Incentive Plan, as it may be amended from time to time (the “Plan”) under which the Company is authorized to grant phantom unit awards to certain employees and service providers of the Company;

WHEREAS, a copy of the Plan has been furnished to you and shall be deemed a part of this Phantom Unit Agreement (Employee) (“Agreement”) as if fully set forth herein and the terms capitalized but not defined herein shall have the meanings set forth in the Plan; and

WHEREAS, you desire to accept the phantom unit award made pursuant to this Agreement.

NOW, THEREFORE, in consideration of the mutual covenants set forth herein and for other valuable consideration hereinafter set forth, the parties hereto agree as follows:

1.The Grant. Subject to the conditions set forth below, the Company hereby grants you effective as of the Date of Grant set forth in the Notice of Grant, as a matter of separate inducement but not in lieu of any cash or other compensation for your services for the Company or the Partnership an award (the “Award”) consisting of Phantom Units (“Phantom Units”) covering the aggregate number of Units set forth in the Notice of Grant in accordance with the terms and conditions set forth herein and in the Plan, plus the additional rights to receive possible distribution equivalents, in accordance with the terms and conditions set forth herein.

2.    No Unitholder Rights. The Phantom Units granted pursuant to this Agreement do not and shall not entitle you to any rights of a holder of Units prior to the date Units, if any, are issued to you in settlement of the Award.

3.    Distribution Equivalents. In the event that the Company declares and pays a distribution in respect of its outstanding Units on or after the Date of Grant and, on the record date for such distribution, you hold Phantom Units granted pursuant to this Agreement that have not been settled, the Company shall pay to you an amount in cash equal to the cash distributions you would have received if you were the holder of record as of such record date, of the number of Units related to the portion of your Phantom Units that have not been settled as of such record date, such payment (“Distribution Equivalents”) to be made on or promptly following the date that the Company pays such distribution (however, in no event shall the Distribution Equivalents be paid

later than 30 days following the date on which the Company pays such distribution to its unitholders generally).

4.    Restrictions; Forfeiture. The Phantom Units are restricted in that they cannot be sold, transferred or otherwise alienated or hypothecated until Units related to such Phantom Units are issued pursuant to Section 8 following the removal or expiration of the restrictions as contemplated in Section 5 (and Section 6, if applicable) of this Agreement and as described in the Notice of Grant. In the event you cease to be an employee of the Company and any of its subsidiaries, other than as provided in Section 6 below, the Phantom Units that are not vested on the date of such cessation of employment shall be immediately forfeited.

5.    Expiration of Restrictions and Risk of Forfeiture. The restrictions on the Phantom Units granted pursuant to this Agreement will expire and the Phantom Units will become nonforfeitable as set forth in the Notice of Grant, provided that you remain an employee of the Company and its subsidiaries until the applicable dates and times set forth therein. Phantom Units that have become vested and non-forfeitable as provided in this Agreement are referred to herein as “Vested.”

6.    Termination of Employment.

(a)    Termination Generally. Subject to subsections (b), (c), (d) and (e) below, if your employment relationship with the Company and its subsidiaries is terminated for any reason, then those Phantom Units that have not become Vested as of the date of termination shall become null and void and those Phantom Units shall be forfeited to the Company. The Phantom Units that are Vested as of the date of such termination shall not be forfeited to the Company and will be settled in accordance with Section 8.

(b)    Death or Disability. In the event of termination of your employment due to your (i) death or (ii) total and permanent disability, as determined by the Committee in its sole discretion, in either case, before all of the Phantom Units granted pursuant to this Agreement have become Vested, you will forfeit a number of Phantom Units equal to the number of Phantom Units specified in the Notice of Grant times the percentage that (A) the number of days beginning on the day on which the termination due to death or disability occurs and ending on the last day of the Service Period, (B) bears to the total number of days in the Service Period, and any remaining Phantom Units that are not vested will become Vested; provided, however, that any fractional Phantom Units will become null and void and automatically forfeited. In its sole discretion, the Committee may decide to vest all of the Phantom Units in lieu of the prorated number of Phantom Units as provided in this Section 6(b).

(c)     Retirement. In the event of termination of your employment with the Company and its subsidiaries due to your Retirement before all of the Phantom Units have become Vested, the Phantom Units granted pursuant to this Agreement that have not become Vested as of such date of termination shall become Vested on such date of termination.

(d)    Special Involuntary Termination. In the event of a Special Involuntary Termination, all of the Phantom Units granted pursuant to this Agreement will become Vested.

(e)    Effect of Employment Agreement. Notwithstanding any provision herein to the contrary, in the event of any inconsistency between this Section 6 and any employment, change in control, or similar agreement entered into by and between you and the Company (or any of its subsidiaries), the terms of the employment, change in control or similar agreement shall control, subject to compliance with Section 409A of the Code.

7.    Leave of Absence. With respect to the Award, the Company may, in its sole discretion, determine that if you are on leave of absence for any reason you will be considered to still be in the employ of, or providing services for, the Company or any of its subsidiaries, provided that rights to the Phantom Units during a leave of absence will be limited to the extent to which those rights were earned or vested when the leave of absence began.

8.    Issuance of Units. Units shall be issued to you in settlement of your Vested Phantom Units within 30 days following the date upon which such Phantom Units become Vested in accordance with the Agreement. At the time of settlement, the Company shall cause to be issued Units registered in your name in payment of the Award. The Company shall evidence the Units to be issued in payment of the Phantom Units in the manner it deems appropriate. The value of any fractional Phantom Unit shall be rounded down at the time Units, if any, are issued to you. No fractional Units, nor the cash value of any fractional Units, will be issuable or payable to you pursuant to this Agreement. The value of Units shall not bear any interest owing to the passage of time. Neither this Section 8 nor any action taken pursuant to or in accordance with this Section 8 shall be construed to create a trust or a funded or secured obligation of any kind.

9.    Payment of Taxes. The Company may require you to pay to the Company (or an Affiliate of the Company if you are an employee of an Affiliate of the Company), an amount the Company deems necessary to satisfy its (or its Affiliate’s) current or future withholding with respect to federal, state or local income or other taxes that you incur as a result of the Award. With respect to any tax withholding (and to the extent permissible pursuant to Rule 16b-3 under the Exchange Act, if applicable), you may (a) direct the Company to withhold from the Units to be issued to you under this Agreement the number of Units necessary to satisfy the Company’s withholding of such taxes, which determination will be based on the Units’ Fair Market Value at the time such determination is made; (b) deliver to the Company Units sufficient to satisfy the Company’s tax withholding, based on the Units’ Fair Market Value at the time such determination is made; or (c) deliver cash to the Company sufficient to satisfy its tax withholding. If you desire to elect to use the unit withholding option described in subparagraph (a), you must make the election at the time and in the manner the Company prescribes and the maximum number of Units that may be so withheld or surrendered shall be a number of Units that have an aggregate Fair Market Value on the date of withholding or repurchase of up to the aggregate amount of such tax liabilities determined based on the greatest withholding rates for you in your relevant federal, state, foreign and/or local tax jurisdiction, including payroll taxes, that may be utilized without creating adverse accounting treatment with respect to the Award. The Company, in its discretion, may deny your request to satisfy its tax withholding using a method described under subparagraph (a) or (b). In the event the Company determines that the aggregate Fair Market Value of the Units withheld as payment of any tax withholding is insufficient to discharge that tax withholding, then you must pay to the Company, in cash, the amount of that deficiency immediately upon the Company’s request.

10.    Adjustment of Phantom Units. The number of Phantom Units granted to you pursuant to this Agreement shall be adjusted to reflect distributions of the Partnership paid in units, unit splits or other changes in the capital structure of the Partnership, all in accordance with the Plan. All provisions of this Agreement shall be applicable to such new or additional or different units or securities distributed or issued pursuant to the Plan to the same extent that such provisions are applicable to the units with respect to which they were distributed or issued. In the event that the outstanding Units of the Partnership are exchanged for a different number or kind of units or other securities, or if additional, new or different units are distributed with respect to the Units through merger, consolidation, or sale of all or substantially all of the assets of the Partnership, each remaining unit subject to this Agreement shall have substituted for it a like number and kind of units or shares of new or replacement securities as determined in the sole discretion of the Committee, subject to the terms and provisions of the Plan.

11.    Compliance with Securities and Other Applicable Laws. Notwithstanding any provision of this Agreement to the contrary, the issuance of Units will be subject to compliance with all applicable requirements of federal, state, or foreign law with respect to such securities and with the requirements of any stock exchange or market system upon which the Units may then be listed. No Units will be issued hereunder if such issuance would constitute a violation of any applicable federal, state, or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Units may then be listed. In addition, Units will not be issued hereunder unless (a) registration statement under the Securities Act, is at the time of issuance in effect with respect to the Units issued or (b) in the opinion of legal counsel to the Company, the Units issued may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any Units subject to the Award will relieve the Company of any liability in respect of the failure to issue such Units as to which such requisite authority has not been obtained. As a condition to any issuance hereunder, the Company may require you to satisfy any qualifications that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect to such compliance as may be requested by the Company. From time to time, the Board and appropriate officers of the Company are authorized to take the actions necessary and appropriate to file required documents with governmental authorities, stock exchanges, and other appropriate Persons to make Units available for issuance.

12.    Legends. The Company may at any time place legends referencing any restrictions imposed on the Units pursuant to Sections 4 and 11 of this Agreement on all certificates representing Units issued with respect to this Award.

13.    Furnish Information. You agree to furnish to the Company all information requested by the Company to enable it to comply with any reporting or other requirements imposed upon the Company by or under any applicable statute or regulation.

14.    Remedies. The Company shall be entitled to recover from you reasonable attorneys’ fees incurred in connection with the successful enforcement of the terms and provisions of this

Agreement whether by an action to enforce specific performance or for damages for its breach or otherwise to the extent allowed by applicable law.

15.    Execution of Receipts and Releases. Any payment of cash or any issuance or transfer of Phantom Units or other property to you, or to your legal representative, heir, legatee or distributee, in accordance with the provisions hereof, will, to the extent thereof, be in full satisfaction of all claims of such Persons hereunder. In addition, the Company may require you or your legal representative, heir, legatee or distributee, as a condition precedent to such payment or issuance, to execute a general release of all claims in favor of the Company, the Partnership, any Affiliate and the employees, officers, stockholders or board members of the foregoing in such form as the Company may determine; provided, however, that any review period under such release will not modify the date of settlement with respect to your Award.

16.    Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any applicable law, then such provision will be deemed to be modified to the minimum extent necessary to render it legal, valid and enforceable; and if such provision cannot be so modified, then this Agreement will be construed as if not containing the provision held to be invalid, and the rights and obligations of the parties will be construed and enforced as if the illegal, invalid or unenforceable provision had never been included herein.

17.    Administration. This Agreement shall at all times be subject to the terms and conditions of the Plan. The Committee shall have sole and complete discretion with respect to all matters reserved to it by the Plan and decisions of a majority of the Committee with respect thereto and this Agreement shall be final and binding upon you and the Company. In the event of any conflict between the terms and conditions of this Agreement and the Plan, the provisions of the Plan shall control.

18.    Right of the Company and Subsidiaries to Terminate Services. Nothing in this Agreement confers upon you the right to continue in the employ of or performing services for the Partnership or the Company or any of its subsidiaries, or interfere in any way with the rights of the Partnership or the Company (or any of its subsidiaries) to terminate your employment or service relationship at any time.

19.    Governing Law. All questions arising with respect to the provisions of this Agreement shall be determined by application of the laws of the State of Texas, without giving any effect to any conflict of law provisions thereof, except to the extent Texas state law is preempted by federal law. The obligation of the Company to sell and deliver Units hereunder is subject to applicable laws and to the approval of any governmental authority required in connection with the authorization, issuance, sale, or delivery of such Units.

20.    Consent to Texas Jurisdiction and Venue. You hereby consent and agree that state courts located in Dallas, Texas and the United States District Court for the Northern District of Texas each shall have personal jurisdiction and proper venue with respect to any dispute between you and the Company arising in connection with the Phantom Units or this Agreement. In any dispute with the Company, you will not raise, and you hereby expressly waive, any objection or defense to any such jurisdiction as an inconvenient forum.

21.    Amendment. This Agreement may be amended the Board or by the Committee at any time (a) if the Board or the Committee determines, in its sole discretion, that amendment is necessary or advisable in light of any addition to or change in any federal or state, tax or securities law or other law or regulation, which change occurs after the Date of Grant and by its terms applies to the Award; or (b) other than in the circumstances described in clause (a) or provided in the Plan, with your consent.

22.    No Liability for Good Faith Determinations. The General Partner, the Partnership, the Company, HFC and the members of the Committee, the Board and the HFC Board shall not be liable for any act, omission or determination taken or made in good faith with respect to this Agreement or the Phantom Units granted hereunder.

23.    No Guarantee of Interests. None of the Board, the HFC Board, the General Partner, the Partnership, HFC nor the Company guarantee the Units from loss or depreciation.

24.    Company Records. Records of the Company or its subsidiaries regarding your period of employment or service, termination of service and/or employment and the reason(s) therefor, leaves of absence, re-employment, and other matters shall be conclusive for all purposes hereunder, unless determined by the Company to be incorrect.

25.    Notice. All notices required or permitted under this Agreement must be in writing and personally delivered or sent by mail and shall be deemed to be delivered on the date on which it is actually received by the person to whom it is properly addressed or, if earlier, the date it is sent via certified United States mail.

26.    Waiver of Notice. Any person entitled to notice hereunder may waive such notice in writing.

27.    Information Confidential. As partial consideration for the granting of the Award hereunder, you hereby agree to keep confidential all information and knowledge, except that which has been disclosed in any public filings required by law, that you have relating to the terms and conditions of this Agreement; provided, however, that such information may be disclosed as required by law and may be given in confidence to your spouse and tax and financial advisors. In the event any breach of this promise comes to the attention of the Company, it shall take into consideration that breach in determining whether to recommend the grant of any future similar award to you, as a factor weighing against the advisability of granting any such future award to you. Nothing in this Agreement will prevent you from: (a) making a good faith report of possible violations of applicable law to any governmental agency or entity or (b) making disclosures that are protected under the whistleblower provisions of applicable law. For the avoidance of doubt, nothing herein shall prevent you from making a disclosure that: (i) is made (A) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Further, an individual who files a lawsuit for retaliation by an employer of reporting a suspected violation of law may make disclosures without violating this Section 27 to the attorney of the individual and use such information in the court proceeding.

28.    Clawback. This Agreement is subject to any written clawback policies that the Company, with the approval of the Board or the Committee, may adopt to the extent allowed by applicable law. Any such policy may subject your Award and amounts paid or realized with respect to the Award under this Agreement to reduction, cancelation, forfeiture or recoupment if certain specified events or wrongful conduct occur, including but not limited to an accounting restatement due to the Company’s or Partnership’s material noncompliance with financial reporting regulations or other events or wrongful conduct specified in any such clawback policy adopted by the Company or Partnership, including any policy to conform to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and rules promulgated thereunder by the Securities and Exchange Commission and that the Company or the Partnership determines should apply to this Agreement.

29.    Section 409A. It is intended that the Phantom Units awarded hereunder shall comply with the requirements of Section 409A of the Code (and any regulations and guidelines issued thereunder), and this Agreement shall be interpreted on a basis consistent with such intent. Payments shall only be made on an event and in a manner permitted by Section 409A of the Code. Each payment under this Agreement is considered a separate payment for purposes of Section 409A of the Code. This Agreement may be amended without your consent in any respect deemed by the Committee to be necessary in order to preserve compliance with Section 409A of the Code. All payments to be made upon a termination of employment under this Agreement may only be made upon a “separation from service” under Section 409A of the Code. In no event may you, directly or indirectly, designate the calendar year of a payment. Notwithstanding anything in this Agreement to the contrary, if you are a “specified employee” under Section 409A of the Code at the time of separation from service and if payment of any amount under this Agreement is required to be delayed for a period of six months after the separation from service pursuant to Section 409A of the Code, payment of such amount shall be delayed as required by Section 409A of the Code, and the accumulated postponed amount shall be paid in a lump sum payment within 10 days after the end of the six-month period. If you die during the postponement period prior to the payment of postponed amount, the accumulated postponed amount shall be paid to the personal representative of your estate within 60 days after the date of your death.

30.    Successors. This Agreement shall be binding upon you, your legal representatives, heirs, legatees and distributees, and upon the Company, its successors and assigns.

31.    Company Action. Any action required of the Company shall be by resolution of the Board or by a person or entity authorized to act by resolution of the Board.
