Ladies and Gentlemen:

Par Pacific Holdings, Inc., a Delaware corporation (the “Company”), confirms its agreement with ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated (“▇▇▇▇▇▇▇ ▇▇▇▇▇”) and each of the other Initial Purchasers named in Schedule A hereto (collectively, the “Initial Purchasers,” which term shall also include any initial purchaser substituted as hereinafter provided in Section 11 hereof), for whom ▇▇▇▇▇▇▇ ▇▇▇▇▇ is acting as Representative (in such capacity, the “Representative”), with respect to (i) the sale by the Company and the purchase by the Initial Purchasers, acting severally and not jointly, of $100,000,000 aggregate principal amount of the Company’s 5.00% Convertible Senior Notes due 2021 (the “Initial Securities”) and (ii) the grant by the Company to the Initial Purchasers, acting severally and not jointly, of an option to purchase all or any part of the additional $15,000,000 aggregate principal amount of its 5.00% Convertible Senior Notes due 2021 (the “Option Securities” and, together with the Initial Securities, the “Securities”). The Securities are to be issued pursuant to an indenture dated as of June 16, 2016 (the “Indenture”) between the Company and Wilmington Trust, National Association, as trustee (the “Trustee”). The Notes will be convertible into cash, shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), including any such shares issuable upon conversion in connection with a “make-whole fundamental change” (as defined in the Final Offering Memorandum) (the “Underlying Common Stock”), or a combination of cash and shares of Common Stock, at the Company’s election, as set forth in the Final Offering Memorandum.

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (“Subsequent Purchasers”) at any time after this Agreement has been executed and delivered. The Securities are to be offered and sold through the Initial Purchasers without being registered under the Securities Act of 1933, as amended (the “1933 Act”), in reliance upon exemptions therefrom. Pursuant to the terms of the Securities and the Indenture, investors that acquire Securities may only resell or otherwise transfer such Securities if such Securities are hereafter registered under the 1933 Act or if an exemption from the registration requirements of the 1933 Act is available (including the exemption afforded by Rule 144A (“Rule 144A”) of the rules and regulations promulgated under the 1933 Act (the “1933 Act Regulations”) by the Securities and Exchange Commission (the “Commission”)).

The Company has prepared and delivered to each Initial Purchaser copies of a preliminary offering memorandum dated June 15, 2016 prior to the Applicable Time (as defined below) (the “Preliminary Offering Memorandum”) and has prepared and will deliver to each Initial Purchaser, on the date hereof or the next succeeding day, copies of a final offering memorandum (the “Final Offering Memorandum”), each for use by such Initial Purchaser in connection with its solicitation of purchases of, or offering of, the Securities. “Offering Memorandum” means, with respect to any date or time referred to in this Agreement, the most recent offering memorandum (whether the Preliminary Offering Memorandum or the Final Offering Memorandum, or any amendment or supplement to either such document), including exhibits thereto and any documents incorporated therein by reference, which has been prepared and delivered by the Company to the Initial Purchasers, in the case of the Preliminary Offering Memorandum prior to the Applicable Time, in connection with their solicitation of purchases of, or offering of, the Securities. The Company will prepare a final term sheet reflecting the final terms of the Securities, in the form set forth in Schedule B hereto (the “Final Term Sheet”), and will deliver such Final Term Sheet to the Initial Purchasers prior to the Applicable Time in connection with their solicitation of purchases of, or offering of, the Securities. The Company agrees that, unless it obtains the prior written consent of the Representative, it will not make any offer relating to the Securities by any written materials other than the Offering Memorandum and the Issuer Written Information. “Issuer Written Information” means (i) any writing intended for general distribution to investors as evidenced by its being specified in Schedule C hereto, including the Final Term Sheet, and (ii) any “road show” that is a “written communication” within the meaning of the 1933 Act. “General Disclosure Package” means the Preliminary Offering Memorandum and any Issuer Written Information specified on Schedule C hereto and issued at or prior to 8:45 A.M., New York City time, on June 16, 2016 or such other time as agreed by the Company and ▇▇▇▇▇▇▇ ▇▇▇▇▇ (such date and time, the “Applicable Time”).

The Securities will be issued pursuant to an indenture, to be dated as of June 21, 2016 (the “Indenture”), between the Company and Wilmington Trust, National Association, as trustee (the “Trustee”). The Securities will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”), pursuant to a letter of representations to be dated on or before the Closing Time (as defined below) (the “DTC Agreement”), among the Company, the Trustee and the Depositary.

It is understood and agreed by the parties hereto that on June 14, 2015, Black Elk Refining, LLC, a Delaware limited liability company (“Black Elk”), Par Wyoming, LLC, a Delaware limited liability company, and the Company, entered into a Unit Purchase Agreement (the “Acquisition Agreement”) pursuant to which, among other things, Black Elk agreed to sell, transfer, assign, convey and deliver to the Company 100% of the issued and outstanding membership interests (the “Membership Interests”) in Hermes Consolidated, LLC, a Delaware limited liability company (d/b/a Wyoming Refining Company) and wholly owned subsidiary of Black Elk, and the Company agreed to purchase, acquire and accept the Membership Interests, for total consideration of approximately $270.1 million, including approximately $58 million of Wyoming Refining Company’s indebtedness (the “Black Elk Acquisition”), if and when the transactions contemplated by the Acquisition Agreement are completed.

Holders of the Securities (including the Initial Purchasers and their direct and indirect transferees) will be entitled to the benefits of a Registration Rights Agreement, to be entered into at the Closing Time (as defined below) (the “Registration Rights Agreement”), pursuant to which the Company will be required to file with the Commission under the circumstances set forth therein, a shelf registration statement pursuant to Rule 415 of the 1933 Act relating to the resale of the Underlying Common Stock by certain holders of the Securities, and in each case, to use its best efforts to cause such registration statements to be declared effective.

Pursuant to that certain backstop agreement dated June 14, 2016 by and among the Company, funds managed by Highbridge Capital Management, LLC and funds managed on behalf of Whitebox Advisors LLC, certain investors have committed to fully backstop the sale by the Company and the purchase by the Initial Purchasers of the Securities (the “Backstop Agreement”).

The Acquisition Agreement, this Agreement, the Registration Rights Agreement, the DTC Agreement, the Delayed Draw Term Loan and Bridge Loan Credit Agreement (as defined below), the Indenture and Backstop Agreement are referred to herein as the “Transaction Documents.”

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Company. The Company represents and warrants to each Initial Purchaser as of the date hereof, the Applicable Time, the Closing Time (as defined below) and any Date of Delivery (as defined below), and agrees with each Initial Purchaser, as follows:

(i) General Disclosure Package; Rule 144A Eligibility. The Company hereby confirms that it has authorized the use of the General Disclosure Package, including the Preliminary Offering Memorandum and the Final Term Sheet, and the Final Offering Memorandum in connection with the offer and sale of the Securities by the Initial Purchasers. The Securities are eligible for resale pursuant to Rule 144A and will not be, at the Closing Time, of the same class as securities listed on a national securities exchange registered under Section 6 of the 1934 Act, or quoted in a U.S. automated interdealer quotation system.

(ii) No Registration Required; No General Solicitation. Subject to compliance by the Initial Purchasers with the representations and warranties of the Initial Purchasers and the procedures set forth in Section 6 hereof, it is not necessary in connection with the offer, sale and delivery of the offered Securities to the Initial Purchasers and to each Subsequent Purchaser in the manner contemplated by this Agreement, the General Disclosure Package and the Final Offering Memorandum to register the Securities under the 1933 Act or to qualify the Indenture under the Trust Indenture Act of 1939, as amended. None of the Company, its Affiliates (as defined below) or any person acting on its or any of their behalf (other than the Initial Purchasers, as to whom the

Company makes no representation) has engaged, in connection with the offering of the offered Securities, in any form of general solicitation or general advertising within the meaning of Rule 502(c) under the 1933 Act Regulations.

(iii) Accurate Disclosure. As of the Applicable Time, neither (A) the General Disclosure Package nor (B) any Issuer Written Information, when considered together with the General Disclosure Package, included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Final Offering Memorandum, as of its date, at the Closing Time or at any Date of Delivery, does not and will not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The documents incorporated or deemed to be incorporated by reference in the General Disclosure Package and the Final Offering Memorandum, when such documents incorporated by reference were filed with the Commission, as the case may be, when read together with the other information in the General Disclosure Package or the Final Offering Memorandum, as the case may be, did not and will not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The representations and warranties in this subsection shall not apply to statements in or omissions from the General Disclosure Package or the Final Offering Memorandum made in reliance upon and in conformity with written information furnished to the Company by any Initial Purchaser through the Representative expressly for use therein. For purposes of this Agreement, the only information so furnished shall be the information in the first paragraph under the heading “Plan of Distribution–Commissions and Discounts” and the information in the first paragraph under the heading “Plan of Distribution–Price Stabilization, Short Positions” in the Offering Memorandum (collectively, the “Initial Purchaser Information”).

(iv) Independent Accountants.

The supporting schedules, if any, present fairly, in all material respects, in accordance with GAAP the information required to be stated therein. The selected financial data and the summary financial information included in the General Disclosure Package and the Final Offering Memorandum present fairly, in all material respects, the information shown therein and have been compiled on a basis consistent with that of the audited financial statements included therein. Except as included or incorporated by reference therein, no historical or pro forma financial statements or supporting schedules are required to be included or incorporated by reference in the Offering Memorandum under the 1933

The execution, delivery and performance of this Agreement, the Transaction Documents and the consummation of the Transactions contemplated herein and in the General Disclosure Package and the Final Offering Memorandum (including the issuance and sale of the Securities, the issuance of the Underlying Common Stock upon conversion of the Securities, and the use of the proceeds from the sale of the Securities as described therein under the caption “Use of Proceeds”) and compliance by the Company with its obligations hereunder have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any properties or assets of the Company or any subsidiary pursuant to, the Agreements and Instruments (except for such conflicts, breaches, defaults or Repayment Events or liens, charges or encumbrances that would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter, by-laws or similar organizational document of the Company or any of its subsidiaries or any law, statute, rule, regulation, judgment, order, writ or decree of any Governmental Entity.

(xxi) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any Governmental Entity is necessary or required for the performance by the Company of its obligations hereunder, in connection with the offering, issuance or sale of the Securities hereunder or the consummation of the Transactions contemplated by this Agreement, except such as have been already obtained or as may be required under the 1933 Act, the 1933 Act Regulations, the rules of the NYSE MKT LLC (“NYSE MKT”), state securities laws or the rules of Financial Industry Regulatory Authority, Inc. (“FINRA”).

The Company and its subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate Governmental Entities necessary to conduct the business now operated by them, except where the failure so to possess would not reasonably be expected to result in a Material Adverse Effect. The Company and its subsidiaries are in compliance with the terms and conditions of all Governmental Licenses, except where the failure so to comply would not reasonably be expected to result in a Material Adverse Effect. All of the Governmental Licenses are valid and in full force and effect, except where the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any Governmental Licenses which, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to result in a Material Adverse Effect.

(xxiii) Title to Property. The Company and its subsidiaries have good and marketable title to all real property owned by them and good title to all other properties owned by them, in each case, free and clear of all mortgages, pledges, liens, security interests, claims, restrictions or encumbrances of any kind except such as (A) are described in the General Disclosure Package and the Final Offering Memorandum or (B) do not, singly or in the aggregate, materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company or any of its subsidiaries; and all of the leases and subleases material to the business of the Company and its subsidiaries, considered as one enterprise, and under which the Company or any of its subsidiaries holds properties described in the General Disclosure Package or the Final Offering Memorandum, are in full force and effect, and neither the Company nor any such subsidiary has any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or any subsidiary under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company or such subsidiary to the continued possession of the leased or subleased premises under any such lease or sublease except to the extent any claim or adverse effect on the Company or such subsidiary’s rights thereto would not reasonably be expected to result in a Material Adverse Effect.

(xxiv) Possession of Intellectual Property. The Company and its subsidiaries own or have valid, binding and enforceable licenses or other rights under, or can acquire on reasonable terms, adequate patents, patent rights, licenses, inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), trademarks, service marks, trade names or other intellectual property (collectively, “Intellectual Property”) necessary to carry on the business now operated by them, and neither the Company nor any of its subsidiaries has received any notice of any claim of infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances which would reasonably be expected to render any Intellectual Property invalid or inadequate to protect the interest of the Company or any of its subsidiaries therein, and which infringement or conflict (if the subject of any unfavorable decision, ruling or finding) or invalidity or inadequacy, would reasonably be expected to result in a Material Adverse Effect.

(xxv) Environmental Laws. Except as described in the General Disclosure Package and the Final Offering Memorandum or as would not, singly or in the aggregate, result in a Material Adverse Effect, (A) neither the Company nor any of its subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products, asbestos-containing materials or mold (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (B) the Company and its subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements, (C) there are no pending or, to the knowledge of the Company, threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigations or proceedings relating to any Environmental Law against the Company or any of its subsidiaries and (D) there are no events or circumstances that would reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or Governmental Entity, against or affecting the Company or any of its subsidiaries relating to Hazardous Materials or any Environmental Laws.

(xxvi) Accounting Controls and Disclosure Controls. The Company and each of its subsidiaries maintain a system of internal control over financial reporting (as defined under Rule 13-a15 and 15d-15 under the 1934 Act Regulations) to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, which system is effective in all material respects for the purpose for which it was designed. The Company and each of its subsidiaries also maintain a system of internal accounting controls sufficient to provide reasonable assurances that (A) transactions are executed in accordance with management’s general or specific authorization; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (C) access to assets is permitted only in accordance with management’s general or specific authorization; (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (E) the interactive data in eXtensible Business Reporting Language incorporated by reference in the General Disclosure Package and the Final

Offering Memorandum fairly presents the information called for in all material respects and is prepared in accordance with the Commission’s rules and guidelines applicable thereto. Except as described in the General Disclosure Package and the Final Offering Memorandum, since the end of the Company’s most recent audited fiscal year, there has been (1) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (2) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company and each of its subsidiaries have established and maintain disclosure controls and procedures (as defined in Rule 13a-15 and Rule 15d-15 under the 1934 Act Regulations) that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and is accumulated and communicated to the Company’s management, including its principal executive officer or officers and principal financial officer or officers, as appropriate, to allow timely decisions regarding required disclosure, which system is effective in all material respects for the purpose for which it was designed.

(xxvii) Compliance with the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act. There is and has been no failure on the part of the Company or, to the knowledge of the Company, any of the Company’s directors or officers, in their capacities as such, to comply in all material respects with the applicable provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations promulgated in connection therewith, including Section 402 related to loans and Sections 302 and 906 related to certifications.

(xxviii) Payment of Taxes. All United States federal income tax returns of the Company and its subsidiaries required by law to be filed through the date hereof (after giving effect to extensions) have been filed and all United States federal income taxes shown by such returns or otherwise assessed, which are due and payable, have been paid, except assessments against which appeals have been or will be promptly taken and as to which adequate reserves have been provided. The Company and its subsidiaries have filed all other tax returns that are required to have been filed through the date hereof (after giving effect to extensions) by them pursuant to applicable foreign, state, local or other law except insofar as the failure to file such returns would not reasonably be expected to result in a Material Adverse Effect, and have paid all taxes due pursuant to such returns or pursuant to any assessment received by the Company and its subsidiaries, except for such taxes, if any, as are being contested in good faith and as to which adequate reserves have been established by the Company. The charges, accruals and reserves on the books of the Company in respect of any income and corporation tax liability for any years not finally determined are adequate to meet any assessments or re-assessments for additional income tax for any years not finally determined, except to the extent of any inadequacy that would not reasonably be expected to result in a Material Adverse Effect.

SECTION 2. Sale and Delivery to Initial Purchasers; Closing.

(a) Initial Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Initial Purchaser and each Initial Purchaser, severally and not jointly, agrees to purchase from the Company, at the price set forth in Schedule A, the aggregate principal amount of Initial Securities set forth in Schedule A opposite the name of such Initial Purchaser, plus any additional principal amount of Initial Securities which such

Initial Purchaser may become obligated to purchase pursuant to the provisions of Section 11 hereof, subject, in each case, to such adjustments among the Initial Purchasers as ▇▇▇▇▇▇▇ ▇▇▇▇▇ in its sole discretion shall make to ensure that any sales or purchases are in authorized denominations.

(b) Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Initial Purchasers, severally and not jointly, to purchase the Option Securities, at the price set forth in Schedule A. The option hereby granted may be exercised for 30 days after the date hereof and may be exercised in whole or in part from time to time upon notice by the Representative to the Company setting forth the amount of Option Securities as to which the several Initial Purchasers are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representative, but shall not be later than seven full business days nor earlier than two full business days after the exercise of said option, nor in any event prior to the Closing Time. If the option is exercised as to all or any portion of the Option Securities, each of the Initial Purchasers, acting severally and not jointly, will purchase that proportion of the total principal amount of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Initial Purchaser bears to the total principal amount of Initial Securities, subject in each case to such adjustments as ▇▇▇▇▇▇▇ ▇▇▇▇▇ in its sole discretion shall make to ensure that any sales or purchases are in authorized denominations.

(c) Payment. Payment of the purchase price for, and delivery of certificates or security entitlements for, the Initial Securities shall be made at the offices of ▇▇▇▇▇▇ & ▇▇▇▇▇▇ L.L.P., ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, or at such other place as shall be agreed upon by the Representative and the Company, at 9:00 A.M. (New York City time) on the third (fourth, if the pricing occurs after 4:30 P.M. (New York City time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 11 ), or such other time not later than ten business days after such date as shall be agreed upon by the Representative and the Company (such time and date of payment and delivery being herein called the “Closing Time”).

In addition, in the event that any or all of the Option Securities are purchased by the Initial Purchasers, payment of the purchase price for, and delivery of certificates or security entitlements for, such Option Securities shall be made at the above mentioned offices, or at such other place as shall be agreed upon by the Representative and the Company, on each Date of Delivery as specified in the notice from ▇▇▇▇▇▇▇ ▇▇▇▇▇ to the Company.

Payment shall be made to the Company by wire transfer of immediately available funds to bank accounts designated by the Company against delivery to the Representative for the respective accounts of the Initial Purchasers of certificates or security entitlements for the Securities to be purchased by them. It is understood that each Initial Purchaser has authorized the Representative, for its account, to accept delivery of, receipt for and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. ▇▇▇▇▇▇▇ ▇▇▇▇▇, individually and not as representative of the Initial Purchasers, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities and Option Securities, if any, to be purchased by any Initial Purchaser whose funds have not been received by the Closing Time ore the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Initial Purchaser from its obligations hereunder.

SECTION 3. Covenants of the Company. The Company covenants with each Initial Purchaser as follows:

(a) Delivery of Offering Memorandum. The Company has delivered to each Initial Purchaser, without charge, as many copies of the Preliminary Offering Memorandum (as amended or supplemented) thereto and documents incorporated by reference therein as such Initial Purchaser

The Company will advise the Representative promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities or the Underlying Common Stock for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its commercially reasonable efforts to obtain the withdrawal thereof at the earliest possible moment.

(iii) Restriction on Repurchases. Except as permitted under the Registration Rights Agreement, until the expiration of one year after the original issuance of the offered Securities, the Company will not, and will cause its Affiliates not to, resell any offered Securities that have been reacquired by them, which are “restricted securities” (as such term is defined under Rule 144(a)(3)), whether as beneficial owner or otherwise (except as agent acting as a securities broker on behalf of and for the account of customers in the ordinary course of business in unsolicited broker’s transactions).

Each Initial Purchaser severally represents and agrees that it has not offered or sold, and will not offer or sell, any offered Securities constituting part of its allotment within the United States except in accordance with Rule 144A or another applicable exemption from the registration requirements of the 1933 Act. Accordingly, neither it nor any person acting on its behalf has made or will make offers or sales of the Securities in the United States by means of any form of general solicitation or general advertising (within the meaning of Regulation D) in the United States. Each Initial Purchaser will take reasonable steps to inform, and cause each of its affiliates (as such term is defined in Rule 501(b) under the 1933 Act Regulations (each, an “Affiliate”)) to take reasonable steps to inform, persons acquiring Securities from such Initial Purchaser or Affiliate, as the case may be, in the United States that the Securities (A) have not been and will not be registered under the 1933 Act, (B) are being sold to them without registration under the 1933 Act in reliance on Rule 144A or in accordance with another exemption from registration under the 1933 Act, as the case may be, and (C) may not be offered, sold or otherwise transferred except (1) to the Company, (2) outside the United States in accordance with Regulation S or (3) inside the United States in accordance with (x) Rule 144A to a person whom the seller reasonably believes is a Qualified Institutional Buyer that is purchasing such Securities for its own account or for the account of a Qualified Institutional Buyer to whom notice is given that the offer, sale or transfer is being made in reliance on Rule 144A or (y) pursuant to another available exemption from registration under the 1933 Act.

SECTION 7. Indemnification.

(a) Indemnification of Initial Purchasers by the Company. The Company agrees to indemnify and hold harmless each Initial Purchaser, its Affiliates, its selling agents and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact included in any Preliminary Offering Memorandum, the Final Offering Memorandum, the information contained in the Final Term Sheet, any Issuer Written Information or any other information used by or on behalf of the Company in connection with the offer or sale of the Securities (or any amendment or supplement to the foregoing) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any

investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by ▇▇▇▇▇▇▇ ▇▇▇▇▇), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in any Preliminary Offering Memorandum, the Final Offering Memorandum or the information contained in the Final Term Sheet (or any amendment or supplement to the foregoing) in reliance upon and in conformity with the Initial Purchaser Information.

(b) Indemnification of Company, Directors and Officers. Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Company, its directors, its officers and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in any Preliminary Offering Memorandum, the Final Offering Memorandum or the information contained in the Final Term Sheet (or any amendment or supplement to the foregoing) in reliance upon and in conformity with the Initial Purchaser Information.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by ▇▇▇▇▇▇▇ ▇▇▇▇▇, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 8. Contribution. If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount received by the Initial Purchasers, on the other hand, bear to the aggregate offering price of the Securities as set forth on the cover of the Final Offering Memorandum.

The relative fault of the Company, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, on the other hand, or by the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 8, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it and distributed to the public were offered to the public exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Initial Purchaser’s Affiliates and selling agents shall have the same rights to contribution as such Initial Purchaser, and each director of the Company, each officer of the Company, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the aggregate principal amount of the Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 9. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Initial Purchaser or its Affiliates or selling agents, any person controlling any Initial Purchaser, its officers or directors, any person controlling the Company and (ii) delivery of and payment for the Securities.

SECTION 10. Termination of Agreement.

(a) Termination. The Representative may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, in the judgment of the Representative, since the time of execution of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Final Offering Memorandum, any Material Adverse Effect, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representative, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE MKT, or (iv) if trading generally on the NYSE MKT or the New York Stock Exchange or in the NASDAQ Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream Banking, S.A. or Euroclear plc systems in Europe, or (vi) if a banking moratorium has been declared by either federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 7, 8, 9, 15, 16 and 17 shall survive such termination and remain in full force and effect.

SECTION 11. Default by One or More of the Initial Purchasers. If one or more of the Initial Purchasers shall fail at the Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Initial Purchasers, or any other initial purchasers, to purchase all, but not less than all, of the Defaulted

Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such date, each of the non-defaulting Initial Purchasers shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Initial Purchasers, or

(ii) if the number of Defaulted Securities exceeds 10% of the number of the aggregate principal amount of the Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Initial Purchasers to purchase, and the Company to sell, the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Initial Purchaser.

No action taken pursuant to this Section shall relieve any defaulting Initial Purchaser from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Initial Purchasers to purchase and the Company to sell the relevant Option Securities, as the case may be, either the (i) Representative or (ii) the Company shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the General Disclosure Package or the Final Offering Memorandum or in any other documents or arrangements. As used herein, the term “Initial Purchaser” includes any person substituted for an Initial Purchaser under this Section 11.

SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Initial Purchasers shall be directed to ▇▇▇▇▇▇▇ ▇▇▇▇▇ at ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, attention of Syndicate Department (facsimile: (▇▇▇) ▇▇▇-▇▇▇▇), with a copy to ECM Legal (facsimile: (▇▇▇) ▇▇▇-▇▇▇▇); notices to the Company shall be directed to it at Par Pacific Holdings, Inc., One Memorial Plaza, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, attention of J. ▇▇▇▇▇▇▇ ▇▇▇▇▇▇.

SECTION 13. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the initial offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Initial Purchasers, on the other hand, (b) in connection with the offering of the Securities and the process leading thereto, each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Company, any of its subsidiaries, or its respective stockholders, creditors, employees or any other party, (c) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of the Securities or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company, any of its subsidiaries on other matters) and no Initial Purchaser has any obligation to the Company with respect to the offering of the Securities except the obligations expressly set forth in this Agreement, (d) the Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of each of the Company, and (e) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 14. Parties. This Agreement shall inure to the benefit of and be binding upon the Initial Purchasers and the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Initial Purchasers and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Initial Purchasers and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor by reason merely of such purchase.

SECTION 15. Trial by Jury. The Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates), and each of the Initial Purchasers hereby irrevocably waives, to the fullest extent permitted by applicable law, 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.

SECTION 16. GOVERNING LAW. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF, THE STATE OF NEW YORK WITHOUT REGARD TO ITS CHOICE OF LAW PROVISIONS.

SECTION 17. Consent to Jurisdiction; Waiver of Immunity. Any legal suit, action or proceeding arising out of or based upon this Agreement or the Transactions contemplated hereby shall be instituted in (i) the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court, as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum.

SECTION 18. TIME. TIME SHALL BE OF THE ESSENCE OF THIS AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 19. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

SECTION 20. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

SECTION 21. Xtract Research LLC. The Company hereby agrees that the Initial Purchasers may provide copies of the Preliminary Offering Memorandum and the Final Offering Memorandum relating to the offering of the Securities and any other agreements or documents relating thereto, including, without limitation, any trust indentures, to Xtract Research LLC (“Xtract”) following the completion of the offering for inclusion in an online research service sponsored by Xtract, access to which is restricted to Qualified Institutional Buyers.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Initial Purchasers and the Company in accordance with its terms.

Hedging Restrictions:		In connection with its purchase of Notes, each beneficial owner of the Notes has agreed in writing with the Issuer that until the earlier of (x) the date that is 10 calendar days following the pricing date for the Subscription Rights Offering, if any, and (y) August 9, 2016 (such earlier date, the “Cut-off Date”), neither it nor any of its affiliates will, directly or indirectly: • offer, pledge, sell, short sell or contract to sell any shares of Common Stock; • sell any option or contract to purchase any shares of Common Stock; • purchase any option or contract to sell any shares of Common Stock; • grant any option, right or warrant to purchase any shares of Common Stock; • otherwise transfer or dispose of or transfer any shares of Common Stock; or • enter into any swap or any other agreement that transfers, in whole or in part, the economic consequence of ownership of Common Stock, whether any such swap or transaction is to be settled by delivery of shares or other securities, in cash or otherwise (the foregoing activities, “Share Dispositions” and the foregoing restrictions, the “Hedging Restrictions”); provided, however, the foregoing Hedging Restrictions shall not apply to (1) any purchases, sales or exercises of the transferrable subscription rights issued in the Subscription Rights Offering, if any or (2) any Share Dispositions by ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated or any of its affiliates in connection with its (or any affiliate’s) ordinary course market-making, brokerage or other trading activity unrelated to trading of the Notes. In addition, each beneficial owner of the Notes has agreed in writing that it may not transfer any of its Notes to any other party prior to the Cut-off Date unless that party agrees in writing with the Issuer to be bound by the Hedging Restrictions and this limitation on transfers, if and as applicable.

Schedule B - 1


Restrictions on Ownership:		Notwithstanding any other provision of the Notes, during any period of time in which a person’s beneficial ownership of shares of Common Stock is less than 5%, such person shall not have the right to convert all or any portion of any of its Notes into shares of Common Stock to the extent that, upon and after giving effect to such conversion, such person (together with such person’s affiliates and any other persons or entities whose beneficial ownership of shares of Common Stock would be aggregated with such person’s for purposes of Section 13(d) of the Exchange Act (the “affiliated parties”) (including shares held by any “group” of which such person or any of its affiliated parties is a member)) would have beneficial ownership of more than 4.99% of the total number of shares of Common Stock then issued and outstanding; provided that such person may, from time to time, at its option and upon not less than 61 days’ prior notice to the Issuer, elect to increase such limitation to any other percentage not in excess of 9.99% of the total number of shares of Common Stock then issued and outstanding. Any such increase will not be effective until the 61st day after such notice is delivered to the Issuer. The Issuer will agree under the indenture not to adopt any shareholder rights plan or take any other action that would have the effect of restricting or adversely affecting a person’s election to change such percentage limitation. For the avoidance of doubt, if a person purports to convert any of its Notes into shares of Common Stock and any delivery otherwise owed to such person is not made, in whole or in part, as a result of the then applicable ownership limitation (as determined in accordance with the indenture), then the person’s rights under the Notes pursuant to which such delivery was not made will not be extinguished and instead such Notes will be deemed to have never been converted by such person and will remain outstanding under the indenture. In addition, the election to increase the maximum ownership percentage for purposes of Section 13(d) of the Exchange Act shall be subject to, and in no event affect or otherwise limit, the transfer restrictions contained in Article 11 of the Issuer’s certificate of incorporation.

Registration Rights:		Under a registration rights agreement that the Issuer will enter into with the initial purchasers of the Notes, the Issuer will: • agree to file a shelf registration statement (which shall be an automatic shelf registration statement if it is then a well-known seasoned issuer, or WKSI) with the SEC as soon as practicable following the date hereof, and in any event, on or prior to the 90th day after the first date of original issuance of the Notes, covering resales

Schedule B - 1


		of the shares of Common Stock, if any, issuable upon conversion of the Notes and in respect of any make-whole premium;

		• if it is not a WKSI on such 90th day, use its best efforts to cause the shelf registration statement to become effective within 180 days after the first date of original issuance of the Notes; and • use its best efforts to keep the shelf registration statement effective until the earlier of (1) the 120th calendar day immediately following the maturity date or (2) the date on which there are no longer outstanding any Notes or restricted shares of Common Stock that have been received upon conversion of the Notes or in respect of any make-whole premium. If the Issuer does not fulfill certain of its obligations under the registration rights agreement with respect to the Notes, it will be required to pay liquidated damages to holders of the Notes. If a holder of the Notes converts some or all of its Notes into shares of Common Stock or receives shares of Common Stock in respect of any make-whole premium, such holder will not be entitled to liquidated damages with respect to such shares of Common Stock. However, if a holder of the Notes converts its Notes or if the Issuer delivers any shares of Common Stock in respect of any make-whole premium when there exists a registration default with respect to shares of Common Stock, the Issuer will increase the conversion rate or the amount of such make-whole premium, as the case may be, by 3% as described under “Description of Notes—Registration Rights” in the Preliminary Offering Memorandum instead of paying any liquidated damages on such shares of Common Stock.

Optional Redemption:		If the unit purchase agreement relating to the Issuer’s pending acquisition of Hermes Consolidated, LLC d/b/a Wyoming Refining Company terminates, the Issuer may redeem all, but not less than all, of the outstanding Notes for cash by delivering notice of such redemption on or prior to August 9, 2016, at a redemption price equal to 102% of the principal amount of Notes to be redeemed, plus any accrued and unpaid interest on such Notes to, but excluding, the redemption date (an “Acquisition Redemption”).

		Except as set forth in the immediately preceding paragraph, the Issuer may not redeem the Notes prior to June 20, 2019. The Issuer may redeem for cash all or any portion of the Notes, at its option, on or after June 20, 2019 if the last reported sale price of the Common Stock has been at least 140% of the conversion price then in effect (i) on the trading day immediately preceding the date on which the Issuer provides notice of redemption and (ii) for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the

Schedule B - 1

trading day immediately preceding the date on which the Issuer provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, payable in cash, plus a “make-whole premium” payment or delivery, as the case may be, in cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Issuer’s election, with a value equal to the present value of the remaining scheduled payments of interest on the Notes to be redeemed through June 15, 2021 (excluding interest accrued to, but excluding, the redemption date). The present value of the remaining interest payments will be computed using a discount rate equal to the reference discount rate.

The “reference discount rate” means, in respect of any make-whole premium, the yield to maturity of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two business days prior to such date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the relevant redemption date to the maturity date of the Notes; provided, however, that if the period from the relevant redemption date to the maturity date is less than one year, the weekly average yield on actively traded United States Treasury securities adjusted to a constant maturity of one year will be used. Any such reference discount rate shall be obtained by the Issuer.

If the Issuer elects to satisfy some or all of the make-whole premium through the delivery of shares of Common Stock, then the number of shares of Common Stock a holder will receive will be that number of shares that have a value equal to the cash amount of the make-whole premium payment to be made to such holder in shares, divided by the product of (1) the average of the last reported sale prices of Common Stock over the five trading day period ending on, and including, the third trading day immediately preceding the earlier of (x) if a holder converts its Notes and the relevant conversion date occurs after the date on which the Issuer delivers notice of the relevant redemption (other than an Acquisition Redemption) and prior to the close of business on the scheduled trading day immediately preceding the related redemption date, such conversion date and (y) such redemption date and (2) 97%.

The Issuer must make the make-whole premium payment on all Notes called for redemption (other than for an Acquisition Redemption) prior to June 15, 2021, including Notes converted after the date the Issuer provides the notice of redemption and prior to the close of business on the scheduled trading day immediately preceding the related redemption date.

Schedule B - 1


		The redemption date in respect of any redemption of Notes will not be less than 40 nor more than 60 scheduled trading days following delivery of the relevant redemption notice. No “sinking fund” is provided for the Notes, which means that the Issuer is not required to redeem or retire the Notes periodically. Notwithstanding the foregoing, unless the Issuer has elected cash settlement in respect of all conversions of Notes for which the relevant conversion date occurs after the date on which the Issuer delivers a notice of redemption and prior to the close of business on the scheduled trading day immediately preceding the related redemption date, in no event will the Issuer have the right to optionally redeem the Notes at any time at which a shelf registration statement covering resales of the shares of Common Stock, if any, issuable upon conversion of the Notes (as described under “Description of Notes—Registration Rights” in the Preliminary Offering Memorandum) is not effective or the use of such shelf registration statement is then suspended.

Use of Proceeds:		The Issuer estimates that the net proceeds to it from the Offering will be approximately $96.0 million (or $110.6 million if the initial purchasers exercise their option to purchase additional Notes in full), after deducting estimated underwriting discounts and commissions and estimated expenses payable by the Issuer. The Issuer intends to use the net proceeds from the Offering (including any proceeds from the exercise of the initial purchasers’ option to purchase additional Notes) to fund a portion of the purchase price of the Wyoming Refining Acquisition (as defined in the Preliminary Offering Memorandum) and to prepay $5 million of the outstanding principal amount of the term loan under its delayed draw term loan credit agreement. Pending the closing of the Wyoming Refining Acquisition, the Issuer is required to use approximately $5 million of the net proceeds from the Offering to repay borrowings outstanding under its delayed draw term loan credit agreement and it expects to invest the remainder of the net proceeds from the Offering in short-term liquid investment grade securities. If the Wyoming Refining Acquisition does not close, the Issuer intends to use the net proceeds from the Offering allocated for investment in short-term liquid investment grade securities for general corporate purposes, including working capital, capital expenditures and acquisitions, other than the $5 million used to prepay the outstanding principal amount of the term loan under its delayed draw term loan credit agreement.

Voting:		The indenture governing the Notes will not disregard any Notes owned by affiliates of the Issuer or their subsidiaries for purposes of determining whether holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under the

Schedule B - 1


		indenture. The outcome of any such direction, consent, waiver or other action by holders may be different than if such Notes held by affiliates of the Issuer or their subsidiaries were disregarded for these voting purposes under the indenture.

Subscription Rights Offering:		Following the Offering, the Issuer expects to offer, to all holders of the Common Stock, transferrable subscription rights to purchase shares of Common Stock for an aggregate purchase price of not more than $50 million in a registered public offering. The Offering is not contingent upon the consummation of the Subscription Rights Offering, and the Subscription Rights Offering is not contingent on the consummation of the Offering. The conversion rate of the Notes will not be adjusted for the issuance of any subscription rights to holders of Common Stock in the Subscription Rights Offering, if any, consummated on or prior to September 30, 2016.

The exact stock prices and effective dates may not be set forth in the table above, in which case

•

If the stock price is between two stock prices in the table or the effective date is between two effective dates in the table, the number of additional shares by which the conversion rate will be increased will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock prices and the earlier and later effective dates, as applicable, based on a 365-day year.

Schedule B - 1

•

If the stock price is greater than $80.00 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above as described under “Description of Notes—Conversion Rights—Conversion Rate Adjustments” in the Preliminary Offering Memorandum), no additional shares will be added to the conversion rate.

•

If the stock price is less than $15.63 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above as described under “Description of Notes—Conversion Rights—Conversion Rate Adjustments” in the Preliminary Offering Memorandum), no additional shares will be added to the conversion rate.

Notwithstanding the foregoing, in no event will the conversion rate per $1,000 principal amount of Notes exceed 63.9795 shares of Common Stock, subject to adjustment in the same manner as the conversion rate as set forth under “Description of Notes—Conversion Rights—Conversion Rate Adjustments” in the Preliminary Offering Memorandum.

Re:

Proposed Sale of 5.00% Convertible Senior Notes due 2021 by Par Pacific Holdings, Inc.

Dear Sirs:

The undersigned, a stockholder and/or an officer and/or director of Par Pacific Holdings, Inc., a Delaware corporation (the “Company”), understands that ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated (“▇▇▇▇▇▇▇ ▇▇▇▇▇”) proposes to enter into a purchase agreement (the “Purchase Agreement”) with the Company providing for the purchase and sale of the Company’s 5.00% Convertible Senior Notes due 2021 (the “Securities”). In recognition of the benefit that such an offering will confer upon the undersigned as a stockholder or as an officer and/or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each initial purchaser to be named in the Purchase Agreement that, during the period beginning on the date hereof and ending on the date that is 75 days from the date of the Purchase Agreement (subject to extensions as discussed below), the undersigned will not, without the prior written consent of ▇▇▇▇▇▇▇ ▇▇▇▇▇, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”) or any securities convertible into or exercisable or exchangeable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (collectively, the “Lock-Up Securities”), or exercise any right with respect to, or make any demand for, the registration of any of the Lock-Up Securities, or file or cause to be filed any registration statement in connection therewith, under the Securities Act of 1933, as amended, or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise.

Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer the Lock-Up Securities without the prior written consent of ▇▇▇▇▇▇▇ ▇▇▇▇▇, provided that (1) ▇▇▇▇▇▇▇ ▇▇▇▇▇ receives a signed lock-up agreement for the balance of the lockup period from each donee, trustee, distributee, or transferee, as the case may be (except with respect to item (viii) below), (2) any such transfer shall not involve a disposition for value, (3) such transfers are not required to be reported with the Securities and Exchange Commission on Form 4 in accordance with Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers:

(i)

as a bona fide gift or gifts; or

B-1

(ii)

to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this lock-up agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin); or

(iii)

as a distribution to limited partners, members or stockholders of the undersigned; or

(iv)

to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned; or

(v)

to any beneficiary of the undersigned pursuant to a will or other testamentary document or applicable laws of descent; or

(vi)

to any corporation, partnership, limited liability company or other entity all of the beneficial ownership interests of which are held by the undersigned or the immediate family of the undersigned; or

(vii)

pursuant to a qualified domestic order or in connection with a divorce settlement; or

(viii)

as a surrender to the Company of incentive awards granted under existing equity incentive plans for no additional consideration.

Furthermore, the undersigned may sell shares of Common Stock of the Company purchased by the undersigned on the open market following the purchase and sale contemplated by the Purchase Agreement if and only if (i) such sales are not required to be reported in any public report or filing with the Securities and Exchange Commission, or otherwise and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales.

Notwithstanding the foregoing, the undersigned, in order to satisfy U.S. federal tax obligations due upon the vesting of shares of restricted Common Stock, may dispose of shares of Common Stock to the Company; provided however that shares of Common Stock received upon such vesting shall be subject to the restrictions set forth herein; and provided further, if the undersigned is required to file a report under the Exchange Act, the undersigned shall include a statement in such report to the effect that the filing relates to the withholding of shares by the Company for tax purposes.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions.

Nothing in this Lock-Up Letter Agreement shall prevent the establishment by the undersigned of any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act; provided that it shall be a condition to the establishment of any such Plan that no sales of the Company’s capital stock shall be made pursuant to such a Plan prior to the expiration of the Lock-Up Period; and provided, further, such a Plan may only be established if no public announcement of the establishment or the existence thereof, and no filing with SEC or any other regulatory authority shall be required or shall be made voluntarily by the undersigned, the Company or any other person, prior to the expiration of the Lock-Up Period.

It is understood that, (i) if the Company notifies the Initial Purchasers that it does not intend to proceed with the purchase and sale contemplated by the Purchase Agreement, (ii) if the Purchase

B-2

Agreement does not become effective, (iii) if the Purchase Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities, (iv) if the Registration Statement is withdrawn, or (v) if the Purchase Agreement is not executed by the Company on or prior to June 24, 2016, the undersigned will be released from its obligations under this Lock-Up Letter Agreement.


Very truly yours,
