 Re: Project Safari 

Ladies and Gentlemen: 
 Reference is made to (a) the
Business Combination Agreement dated of even date herewith by and among The Sinclair Companies, a corporation organized under the laws of the State of Wyoming (“Sinclair”), HollyFrontier Corporation, a corporation organized under
the laws of the State of Delaware (“HFC”), and the other parties thereto (as the same may be amended, supplemented or otherwise modified, the “HFC Sinclair Agreement”), (b) the Contribution Agreement dated of even
date herewith by and among Sinclair, Holly Energy Partners, L.P., a limited partnership organized under the laws of the State of Delaware (“HEP” and, together with HFC, the “Parties”, and each of HFC and HEP,
individually, a “Party”), and the other parties thereto (as the same may be amended, supplemented or otherwise modified, the “HEP Sinclair Agreement” and, together with the HFC Sinclair Agreement, the
“Sinclair Agreements”), and (c) the Twenty-First Amended and Restated Omnibus Agreement, dated February 8, 2021, by and among HEP, HFC and the other parties thereto (as may be amended from time to time, the
“Omnibus Agreement”). 
 Consummation of the transactions contemplated by each Sinclair Agreement is conditioned upon consummation of the
transactions contemplated by the other Sinclair Agreement. As a material inducement to each Party to enter into its respective Sinclair Agreement, the Parties are entering into this letter agreement (this “Letter Agreement”) to
memorialize certain agreements between HEP and its subsidiaries (the “HEP Group”) and HFC and its subsidiaries (other than members of the HEP Group) (the “HFC Group”). As used in this Letter Agreement, an
“Affiliate” of HEP or HFC means members of the HEP Group or the HFC Group, respectively. 
 The Parties, each intending to be legally
bound, hereby agree to the following: 
 1.    Intercompany Agreements. Contemporaneously with Closing (as
defined in the HEP Sinclair Agreement) (the “HEP Closing”), each Party hereby agrees that it shall, and shall cause each of its applicable Affiliates to, execute and deliver amendments to the intercompany agreements by and among
members of the HEP Group and the HFC Group (each an “Intercompany Agreement”) identified on Exhibit A hereto to include within the scope thereof the assets to be acquired by HEP pursuant to the HEP Sinclair Agreement (such
assets, the “Sinclair Midstream Assets”), in each case, on the terms identified on Exhibit A hereto. 












 2.    Woods Cross. 

(a)    WX Purchase Agreement. If HFC commits to a Woods Cross Refinery Divestiture Action (as
defined in the HFC Sinclair Agreement), each Party hereby agrees that it shall, and shall cause each of its applicable Affiliates to, execute and deliver the purchase agreement in substantially the form attached hereto as Exhibit B-1 (the “WX Purchase Agreement”); provided, however, that HEP’s obligation in respect of this Section 2(a) shall be conditioned upon (a) the prior or
contemporaneous execution of a definitive agreement with respect to the Woods Cross Refinery Divestiture Action and (b) the closing conditions under the HEP Sinclair Agreement and the HFC Sinclair Agreement having been satisfied or waived. HFC
shall cause any Woods Cross Refinery Divestiture Action to be conditioned on, and become effective at or after, the Closing (as defined in the HFC Sinclair Agreement) (the “HFC Closing”). Prior to the execution of the WX Purchase
Agreement, HEP shall identify all assets of HEP Woods Cross, L.L.C. (“HEP WX”) which are unrelated to the Woods Cross Refinery (such assets, the “Non-WX Assets”). The Non-WX Assets shall include, without limitation, HEP’s refined products terminal located in Spokane, WA. HEP shall transfer the Non-WX Assets (and all associated
liabilities) to an Affiliate of HEP prior to the execution of the WX Purchase Agreement. 

(b)    Intercompany Agreement Amendments. Each Party hereby agrees that if the transactions
contemplated by the WX Purchase Agreement are consummated (the “WX Closing”), then contemporaneously with the WX Closing, it shall, and shall cause each of its applicable Affiliates to, execute and deliver amendments to the
Intercompany Agreements identified on Exhibit B-2 hereto to exclude from the scope thereof the assets that are the subject of the WX Purchase Agreement (the “HEP WX Assets”), in each
case, on the terms identified on Exhibit B-2 hereto. 

(c)    Intercompany Agreement Terminations. If the conditions in
Section 2(b) are met and the Parties and their applicable Affiliates enter into the WX Purchase Agreement, then effective as of the Effective Time (as defined in the WX Purchase Agreement), the Second Amended and Restated
Operating Agreement (Woods Cross), dated as of October 29, 2018, HollyFrontier Woods Cross Refining LLC and Holly Energy Partners – Operating, L.P., is hereby terminated and shall be of no further force effect, except to the extent
expressly provided otherwise therein. 
 3.    Omnibus Agreement - Business Opportunities. 

(a)    Permitted Assets. Each Party hereby acknowledges and agrees that although certain assets
acquired by HFC pursuant to the HFC Sinclair Agreement, including the assets identified on Exhibit C-1 hereto, constitute Permitted Assets (as defined in the Omnibus Agreement) (the “Sinclair
Permitted Assets”) HFC shall have no obligation to offer the Sinclair Permitted Assets to HEP pursuant to Article II of the Omnibus Agreement. 

(b)    Restricted Business Exception. Each Party hereby acknowledges and agrees that the
assets identified on Exhibit C-2 hereto, shall not constitute a Restricted Business (as defined in the Omnibus Agreement) and, therefore, shall not be subject to HEP’s rights under Article II of
the Omnibus Agreement. 

  
 2 













 4.    UNEV Class B. Each Party hereby waives,
and shall cause its applicable Affiliates to waive, application of Section 12.3 of the Amended and Restated Limited Liability Company Agreement of HEP UNEV Holdings LLC dated July 12, 2012 (the “UNEV LLCA”) in respect of
any UNEV Pipeline Divestiture Action (as defined in the HEP Sinclair Agreement). For the avoidance of doubt, this Section 4 shall not act as a waiver of the application of Section 12.3 of the UNEV LLCA to any future
UNEV Sale Event (as defined in the UNEV LLCA). 
 5.    Wrong Pockets. 

(a)    Misdirected Funds. If, following the HFC Closing, any member of the HEP Group (including any
entity acquired by the HEP Group in connection with the HEP Sinclair Agreement, such entity a “Sinclair Midstream Entity”) receives or collects any funds relating to (i) the Downstream Business (as defined in the HFC Sinclair
Agreement) or (ii) any asset of any Sinclair Downstream Entity (as defined below), then HEP shall, or shall cause its applicable Affiliates to, promptly remit such funds to HFC. If, following the HFC Closing, any member of the HFC Group
(including any entity acquired by the HFC Group in connection with the HFC Sinclair Agreement but excluding any Sinclair Midstream Entity, such entity a “Sinclair Downstream Entity”) receives or collects any funds relating to
(y) the Midstream Business (as defined in the HFC Sinclair Agreement) or (z) any asset of any Sinclair Midstream Entity, then HFC shall, or shall cause its applicable Affiliates to, promptly remit such funds to HEP. 

(b)    Misdirected Assets. If, following the HFC Closing, either Party determines that an asset
purportedly acquired by HFC pursuant to the HFC Sinclair Agreement (such asset, a “Sinclair Downstream Asset”) is owned by a Sinclair Midstream Entity, then HEP shall, or shall cause its applicable Affiliates to, promptly transfer,
on an “as is, where is” basis, such Sinclair Downstream Asset to HFC or its applicable Affiliates without any consideration therefor. If, following the HFC Closing, either Party determines that a Sinclair Midstream Asset is owned by a
Sinclair Downstream Entity, then HFC shall, or shall cause its applicable Affiliates to, promptly transfer, on an “as is, where is” basis, such Sinclair Midstream Asset to HEP or its applicable Affiliates without any consideration
therefor. 
  

	 	6.    Miscellaneous.	 



(a)    Amendments and Waivers. No amendment or modification of this Letter Agreement shall be valid
unless it is in writing and signed by each of the Parties. No waiver of any provision of this Letter Agreement shall be valid unless it is in writing and signed by the Party against whom the waiver is sought to be enforced. 

(b)    Choice of Law; Disputes. This Letter Agreement shall be subject to and governed by the laws
of the State of Delaware, excluding any conflicts-of-law rule or principle that might refer the construction or interpretation of this Letter Agreement to the laws of

another state. Any dispute, claim or controversy arising under this Letter Agreement shall be treated as an Arbitrable Dispute (as defined in the Omnibus Agreement) and resolved in the manner
provided in Article VIII of the Omnibus Agreement.

contemplated by this Letter Agreement, each Party agrees to execute and deliver such additional documents and instruments and to perform such additional acts as may be necessary or appropriate to effectuate, carry out and perform all of the terms,
provisions and conditions of this Letter Agreement and all such transactions. 

(e)    Counterparts. This Letter Agreement may be executed in any number of counterparts with the
same effect as if each of the Parties hereto had signed the same document. All counterparts shall be construed together and shall constitute one agreement. This Letter Agreement, to the extent signed and delivered by means of a facsimile machine or
via e-mail in .pdf file format, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original
signed version thereof delivered in person.

the defense of), and the Indemnified Party shall be entitled to have sole control over, the defense or settlement, compromise, admission, or acknowledgment of any third-party action (i) as to which the Indemnifying Party fails to assume the
defense within a reasonable length of time or (ii) to the extent the third-party action seeks an order, injunction, or other equitable relief against the Indemnified Party which, if successful, would materially adversely affect the business,
operations, assets, or financial condition of the Indemnified Party; provided, however, that the Indemnified Party shall make no settlement, compromise, admission, or acknowledgment that would give rise to liability on the part of any Indemnifying
Party without the prior written consent of such Indemnifying Party.

third-party action pursuant to this ARTICLE IX and, in connection therewith, shall furnish such records, information, and testimony and attend such conferences, discovery proceedings, hearings, trials, and appeals as may be reasonably
requested.

which is not subject to Section 9.2 because no third-party action is involved, the Indemnified Party shall notify the Indemnifying Party in writing of any Indemnified Costs which such Indemnified Party claims are subject to
indemnification under the terms hereof. Subject to the limitations set forth in Section 9.4(a), the failure of the Indemnified Party to exercise promptness in such notification shall not amount to a waiver of such claim
unless the resulting delay materially prejudices the position of the Indemnifying Party with respect to such claim. 

9.4    Limitations. The following provisions of this Section 9.4 shall limit the
indemnification obligations hereunder: 
 (a)    Limitation as to Time. The Indemnifying Party shall not be
liable for any Indemnified Costs pursuant to this ARTICLE IX unless a written claim for indemnification in accordance with Section 9.2 or Section 9.3 is given by the
Indemnified Party to the Indemnifying Party with respect thereto at any time prior to the expiration of the applicable statute of limitations. 

(b)    Sole and Exclusive Remedy. Each Party acknowledges and agrees that, after the Closing Date, notwithstanding
any other provision of this Agreement to the contrary, Buyer’s and the other Buyer Indemnified Parties’ and each Seller and the other Seller Indemnified Parties’ sole and exclusive remedy with respect to the Indemnified Costs shall be
in accordance with, and limited by, the provisions set forth in this ARTICLE IX. The Parties further acknowledge and agree that the foregoing is not the remedy for and does not limit the Parties’ remedies for matters covered by the
indemnification provisions contained in the Omnibus Agreement.

 (b)    Any Party may at any time change its address for service from
time to time by giving notice to the other Parties in accordance with this Section 10.2. 

10.3    Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being
enforced under Applicable Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated herein are not
affected in any manner adverse to any Party. Upon such determination that any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to
effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated herein are consummated as originally contemplated to the fullest extent possible. 

10.4    Governing Law; Jurisdiction; Waiver of Jury Trial. This Agreement shall be subject to and governed by the
laws of the State of Delaware, excluding any conflicts-of-law rule or principle that might refer the construction or interpretation of this Agreement to the laws of
another state. Each Party hereby submits to the jurisdiction of the state and federal courts in the State of Texas and to venue in Dallas, Texas. EACH OF THE PARTIES IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 10.5    Arbitration
Provision. Any and all Arbitrable Disputes must be resolved through the use of binding arbitration using three arbitrators, in accordance with the Commercial Arbitration Rules of the American Arbitration Association, as supplemented to the
extent necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the United States Code). If there is any inconsistency between this Section 10.5 and the Commercial Arbitration
Rules or the Federal Arbitration Act, the terms of this Section 10.5 will control the rights and obligations of the Parties. Arbitration must be initiated within the time limits set forth in this Agreement, or if no
such limits apply, then within a reasonable time or the time period allowed by the applicable statute of limitations. Arbitration may be initiated by a Party (“Claimant”) serving written notice on the other Party
(“Respondent”) that the Claimant elects to refer the Arbitrable Dispute to binding arbitration. Claimant’s notice initiating binding arbitration must identify the arbitrator Claimant has appointed. The Respondent shall respond
to Claimant within thirty (30) days after receipt of Claimant’s notice, identifying the arbitrator Respondent has appointed. If the Respondent fails for any reason to name an arbitrator within the
30-day period, Claimant shall petition the American Arbitration Association for appointment of an arbitrator for Respondent’s account. The two arbitrators so chosen shall select a third arbitrator within
thirty (30) days after the second arbitrator has been appointed. The Claimant will pay the compensation and expenses of the arbitrator named by it, and the Respondent will pay the compensation and expenses of the arbitrator named by or for it.
The costs of petitioning for the appointment of an arbitrator, if any, shall be paid by Respondent. The Claimant and Respondent will each pay one-half of the compensation and expenses of the third arbitrator.
All arbitrators must (i) be neutral parties who have never been officers, directors or employees of either Seller, Buyer or any of their respective Affiliates and (ii) have not less than seven (7) years’ experience in the
petroleum transportation industry. The hearing will be conducted in Dallas, Texas and commence within thirty (30) days after the selection of the third arbitrator. Sellers, Buyer and the 

  
 -14- 













 
arbitrators shall proceed diligently and in good faith in order that the award may be made as promptly as possible. Except as provided in the Federal Arbitration Act, the decision of the
arbitrators will be binding on and non-appealable by the Parties hereto. The arbitrators shall have no right to grant or award indirect, consequential, punitive or exemplary damages of any kind. The Arbitrable
Disputes may be arbitrated in a common proceeding along with disputes under other agreements between Sellers, Buyer or their respective Affiliates to the extent that the issues raised in such disputes are related. Without the written consent of the
Parties, no unrelated disputes or third party disputes may be joined to an arbitration pursuant to this Agreement. 

10.6    Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each Party and
their successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to confer upon any other person any rights or remedies of any nature whatsoever under or by reason of this Agreement. 

10.7    Assignment of Agreement. At any time, the Parties may make a collateral assignment of their rights under
this Agreement to any of their bona fide lenders or debt holders, or a trustee or a representative for any of them, and the non-assigning Parties shall execute an acknowledgment of such collateral assignment
in such form as may from time to time be reasonably requested; provided, however, that unless written notice is given to the non-assigning Parties that any such collateral assignment has been foreclosed
upon, such non-assigning Parties shall be entitled to deal exclusively with Sellers or the Partnership, as the case may be, as to any matters arising under this Agreement, the Ancillary Documents or the
Omnibus Agreement (other than for delivery of notices required by any such collateral assignment). Except as otherwise provided in this Section 10.7, neither this Agreement nor any of the rights, interests, or obligations
hereunder may be assigned by any Party without the prior written consent of the other Parties. 

10.8    Captions. The captions in this Agreement are for purposes of reference only and shall not limit or
otherwise affect the interpretation hereof. 
 10.9    Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 

10.10    Director and Officer Liability. The directors, managers, officers, partners and stockholders of the
Partnership, Buyer, Sellers and their respective Affiliates shall not have any personal liability or obligation arising under this Agreement (including any claims that another party may assert) other than, if applicable, as a direct party to or as
an assignee of this Agreement or pursuant to a written guarantee. 
 10.11    Integration. This Agreement,
the Ancillary Documents, the Letter Agreement and the Omnibus Agreement supersede any previous understandings or agreements among the Parties, whether oral or written, with respect to their subject matter. This Agreement, the Ancillary Documents,
the Letter Agreement and the Omnibus Agreement contain the entire understanding of the Parties with respect to the subject matter hereof and thereof. No understanding, representation, promise or agreement, whether oral or written, is intended to be
or shall be included in or form part of this Agreement, the Ancillary Documents, the Letter Agreement or the Omnibus Agreement unless it is contained in a written amendment hereto or thereto and executed by the


  
 -15- 













 
Parties hereto or thereto after the date of this Agreement, the Ancillary Documents, the Letter Agreement or the Omnibus Agreement. To the extent that there is any conflict between the Ancillary
Documents (other than the Omnibus Agreement) and this Agreement, this Agreement shall prevail. 
 10.12    Effect of
Agreement. The Parties ratify and confirm that except as otherwise expressly provided herein, in the event this Agreement conflicts in any way with the Omnibus Agreement or the Letter Agreement, the applicable terms and provisions of the Omnibus
Agreement or the Letter Agreement shall control. 
 10.13    Amendment; Waiver. This Agreement may be amended
only in a writing signed by all parties hereto. Any waiver of rights hereunder must be set forth in writing. A waiver of any breach or failure to enforce any of the terms or conditions of this Agreement shall not in any way affect, limit or waive
any party’s rights at any time to enforce strict compliance thereafter with every term or condition of this Agreement. 

10.14    Survival of Representations and Warranties. The representations and warranties set forth in this Agreement
shall survive the Closing until the expiration of the applicable statute of limitations; provided, however, that any representation that is the subject of a claim for indemnification hereunder which claim was timely made pursuant to
Section 9.4(a) shall survive with respect to such claim until such claim is finally paid or adjudicated.

(e)    any absence of any notice to, or Knowledge of, HFC, of the existence or occurrence of any of the matters or events
set forth in the foregoing subsections (a) through (d); or 
 (f)    any other circumstance which might otherwise
constitute a defense available to, or a discharge of, a guarantor. 
 The obligations of HFC hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by
reason of the invalidity, illegality or unenforceability of the HFC Guaranty Obligations or otherwise. 

11.3    Waiver. HFC hereby waives promptness, diligence, all setoffs, presentments, protests and notice of
acceptance and any other notice relating to any of the HFC Guaranty Obligations and any requirement for Sellers to protect, secure, perfect or insure any security interest or lien or any property subject thereto or exhaust any right or take any
action against the Indemnifying Party, any other entity or any collateral. 
 11.4    Subrogation Waiver. HFC

rights of payment or recovery it may now have or hereafter acquire against the Indemnifying Party until all HFC Guaranty Obligations have been indefeasibly paid.

adjustment, composition, liquidation or reorganization of the Indemnifying Party or such other entity, or for any other reason, all as though such payment had not been made. 

11.6    Continuing Guaranty. This ARTICLE XI is a continuing guaranty and shall (i) remain in
full force and effect until the first to occur of the indefeasible performance and payment in full of all of the HFC Guaranty Obligations, (ii) be binding upon HFC, its successors and assigns and (iii) inure to the benefit of and be
enforceable by Sellers and their respective successors, transferees and assigns. 
 11.7    No Duty to Pursue
Others. It shall not be necessary for Sellers (and HFC hereby waives any rights which HFC may have to require Sellers), in order to enforce such payment by HFC, first to (i) institute suit or exhaust its remedies against the Indemnifying
Party or others liable 

  
 -17- 













 
on the HFC Guaranty Obligations or any other person, (ii) enforce Sellers’ rights against any other guarantors of the HFC Guaranty Obligations, (iii) join the Indemnifying Party or
any others liable on the HFC Guaranty Obligations in any action seeking to enforce this ARTICLE XI, (iv) exhaust any remedies available to Sellers against any security which shall ever have been given to secure the HFC Guaranty
