5

Secured Parties or the Second Priority Secured Parties, the priority and rights as between the First Priority Secured Parties and the Second Priority Secured Parties with respect to the Common Collateral shall be as set forth herein.

2.2 Nature of First Priority Obligations. The Second Priority Representative on behalf of itself and the other Second Priority Secured Parties acknowledges that a portion of the First Priority Obligations represents debt that is revolving in nature and that the amount thereof that may be outstanding at any time or from time to time may be increased or reduced and subsequently reborrowed, and that the terms of the First Priority Obligations may be modified, extended, or amended from time to time, and that the aggregate amount of the First Priority Obligations may be increased, replaced, or refinanced, in each event, without notice to or consent by the Second Priority Secured Parties and without affecting the provisions hereof.

2.3 Agreements Regarding Actions to Perfect Liens.

(a) The Second Priority Representative on behalf of itself and the other Second Priority Secured Parties agrees that UCC-1 financing statements with respect to the Common Collateral filed or recorded by or on behalf of the Second Priority Representative shall be in form satisfactory to the First Priority Representative and shall not be filed or recorded until such time as the First Priority Representative has filed and/or recorded its UCC-1 financing statement with respect to the Common Collateral.

(b) The Second Priority Representative agrees on behalf of itself and the other Second Priority Secured Parties that all pledge agreements (including, without limitation, any Comparable Second Priority Security Document), similar instruments, and financing statements (collectively, “Common Collateral Agreements”) now or thereafter entered into or filed with respect to the Common Collateral in favor of or for the benefit of the Second Priority Representative or the Second Priority Creditors shall be in form and substance satisfactory to the First Priority Representative and shall contain the following notation: “The security interests created by this agreement on the property described herein are junior and subordinate to the security interests on such property created by any pledge agreement or similar instrument now or hereafter granted to JPMorgan Chase Bank, N.A., as Administrative Agent, and its successors and assigns, in such property, in accordance with the provisions of the Intercreditor Agreement dated as of August 31, 2012 among JPMorgan Chase Bank, N.A., as Administrative Agent, Jefferies Finance LLC, as Administrative Agent, Par Petroleum Corporation, and Par Piceance Energy Equity LLC, as amended from time to time.”

(c) The First Priority Representative hereby acknowledges that, to the extent that it holds, or a third party holds on its behalf, physical possession of or “control” (as defined in the Uniform Commercial Code) over Common Collateral pursuant to the Parent Pledge Agreement, such possession or control is also for the benefit of the Second Priority Representative and the other Second Priority Secured Parties solely to the extent required to perfect their security interest in such Common Collateral under the Uniform Commercial Code. Nothing in the preceding sentence shall be construed to impose any duty on the First Priority Representative (or any third party acting on its behalf) with respect to such Common Collateral or provide the Second Priority Representative or any other Second Priority Secured Party with any rights with respect to such Common Collateral beyond those specified in this Agreement and the Second Priority Security Documents, provided that promptly after the occurrence of the First Priority Obligations Payment Date, the First Priority Representative shall (i) deliver to the Second Priority Representative, at Par Piceance’s and/or PPC’s sole cost and expense, the Common Collateral in its

possession or control together with any necessary endorsements in its possession to the extent required by the Second Priority Documents or (ii) direct and deliver such Common Collateral as a court of competent jurisdiction otherwise directs, and provided, further, that the provisions of this Agreement are intended solely to govern the respective Lien priorities as between the First Priority Secured Parties and the Second Priority Secured Parties and shall not impose on the First Priority Secured Parties any obligations in respect of the disposition of any Common Collateral (or any proceeds thereof) that would conflict with prior perfected Liens or any claims thereon in favor of any other Person that is not a Secured Party.

2.4 Restriction on New Liens and Certain PEL Credit Parties. So long as the First Priority Obligations Payment Date has not occurred, the parties hereto agree that (a) there shall be no Lien, and no PEL Credit Party (including Par Piceance) shall have any right to create any Lien, on any assets of any PEL Credit Party securing any Second Priority Obligation other than the Common Collateral, (b) no PEL Credit Party (other than Par Piceance) may be a guarantor of any Second Priority Obligation, and (c) no PEL Credit Party (other than Par Piceance) may be a Credit Party (as defined in the PPC Credit Agreement) or otherwise subject to any covenants set forth in any Second Priority Document.

Upon the occurrence and during the continuance of a default or an event of default under the First Priority Documents, the First Priority Representative and the other First Priority Secured Parties may take and continue any Enforcement Action with respect to the First Priority Obligations and the Common Collateral in such order and manner as they may determine in their sole discretion.

7

(b) they will not contest, oppose, object to, interfere with, hinder, or delay, in any manner, whether by judicial proceedings (including without limitation the filing of an Insolvency Proceeding) or otherwise, any foreclosure, sale, lease, exchange, transfer, or other disposition of the Common Collateral by any First Priority Secured Party or any other Enforcement Action with respect to the Common Collateral taken (or any forbearance from taking any Enforcement Action) by or on behalf of any First Priority Secured Party;

(c) they have no right to (i) direct either the First Priority Representative or any other First Priority Secured Party to exercise any right, remedy, or power with respect to the Common Collateral or pursuant to the Parent Pledge Agreement of the other First Priority Documents or (ii) consent or object to the exercise by the First Priority Representative or any other First Priority Secured Party of any right, remedy, or power with respect to the Common Collateral or pursuant to the Parent Pledge Agreement or the other First Priority Documents or to the timing or manner in which any such right is exercised or not exercised (or, to the extent they may have any such right described in this clause (c), whether as a junior lien creditor or otherwise, they hereby irrevocably waive such right);

(d) they will not institute any suit or other proceeding or assert in any suit, Insolvency Proceeding, or other proceeding any claim against any First Priority Secured Party seeking damages from or other relief by way of specific performance, instructions or otherwise, with respect to, and no First Priority Secured Party shall be liable for, any action taken or omitted to be taken by any First Priority Secured Party in accordance with this Agreement with respect to the Common Collateral or pursuant to the First Priority Documents;

(e) they will not make any judicial or nonjudicial claim or demand or commence any judicial or non-judicial proceedings against any PEL Credit Party (including Par Piceance) under or with respect to any Comparable Second Priority Security Document seeking payment or damages from or other relief by way of specific performance, instructions, or otherwise under or with respect to any Comparable Second Priority Security Document or exercise any right, remedy, or power under or with respect to, or otherwise take any action to enforce any Comparable Second Priority Security Document other than in accordance with this Agreement;

(f) they will not commence judicial or nonjudicial foreclosure proceedings with respect to, seek to have a trustee, receiver, liquidator, or similar official appointed for or over, attempt any action to take possession of any Common Collateral, exercise any right, remedy, or power with respect to, or otherwise take any action to enforce their interest in or realize upon, the Common Collateral or pursuant to any Comparable Second Priority Security Documents; and

(g) they will not seek, and hereby waive any right, to have the Common Collateral or any part thereof marshaled upon any foreclosure or other disposition of the Common Collateral.

3.3 Judgment Creditors. In the event that any Second Priority Secured Party becomes a judgment lien creditor in respect of Common Collateral as a result of its enforcement of its rights as an unsecured creditor, such judgment lien shall be subject to the terms of this Agreement for all purposes (including in relation to the First Priority Liens and the First Priority Obligations) to the same extent as all other Liens in the Common Collateral securing the Second Priority Obligations are subject to the terms of this Agreement.

8

3.4 Cooperation. The Second Priority Representative, on behalf of itself and the other Second Priority Secured Parties, agrees that each of them shall take such actions as the First Priority Representative shall reasonably request in connection with the exercise by the First Priority Secured Parties of their rights set forth herein.

Except as provided in Section 3.6, if any First Priority Secured Party or Second Priority Secured Party shall enforce its rights or remedies in violation of the terms of this Agreement, Par Piceance and PPC shall not be entitled to use such violation as a defense to any action by any First Priority Secured Party or Second Priority Secured Party, nor to assert such violation as a counterclaim or basis for set off or recoupment against any First Priority Secured Party or Second Priority Secured Party.

3.6 Actions Upon Breach.

(a) If any Second Priority Secured Party, contrary to this Agreement, commences or participates in any action or proceeding against Par Piceance or the Common Collateral, Par Piceance, with the prior written consent of the First Priority Secured Representative, may interpose as a defense or dilatory plea the making of this Agreement, and any First Priority Secured Party may intervene and interpose such defense or plea in its or their name or in the name of Par Piceance.

(b) Should any Second Priority Secured Party, contrary to this Agreement, in any way take, attempt to, or threaten to take any action with respect to the Common Collateral (including, without limitation, any attempt to realize upon or enforce any remedy with respect to this Agreement), or fail to take any action when and as required by this Agreement, any First Priority Secured Party (in its own name or in the name of Par Piceance) or Par Piceance may obtain relief against such Second Priority Secured Party by injunction, specific performance, and/or other appropriate equitable relief, it being understood and agreed by the Second Priority Representative on behalf of each Second Priority Secured Party that (i) the First Priority Secured Parties’ damages from its actions may at that time be difficult to ascertain and may be irreparable, and (ii) each Second Priority Secured Party waives any defense that Par Piceance and/or the First Priority Secured Parties cannot demonstrate damage and/or be made whole by the awarding of damages.

(b) The Second Priority Representative shall promptly execute and deliver such release documents and instruments and shall take such further actions as the First Priority Representative shall reasonably request to evidence any release of the Second Priority Lien described in paragraph (a). The Second Priority Representative hereby appoints the First Priority Representative and any officer or duly authorized person of the First Priority Representative, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power of attorney in the place and stead of the Second Priority Representative and in the name of the Second Priority Representative or in the First Priority Representative’s own name, from time to time, in the First Priority Representative’s sole discretion, for the purposes of carrying out the terms of this Section 4.2, to take any and all appropriate action and to

(a) Until the First Priority Obligations Payment Date has occurred, the Second Priority Representative agrees on behalf of itself and the other Second Priority Secured Parties that no Second Priority Secured Party shall, in or in connection with any Insolvency Proceeding with respect to Par Piceance or the Common Collateral, file any pleadings or motions, take any position at any hearing or proceeding of any nature, or otherwise take any action whatsoever, in each case in respect of any of the Common Collateral, including, without limitation, with respect to the determination of any Liens or claims held by the First Priority Representative (including the validity and enforceability thereof) or any other First Priority Secured Party or the value of any claims of such parties under Section 506(a) of the Bankruptcy Code or otherwise, in each case without the prior written consent of the First Priority Representative; provided that (A) the Second Priority Representative or the Second Priority Secured Parties may file a proof of claim or statement of interest in an Insolvency Proceeding, subject to the limitations contained in this Agreement and only if consistent with the terms and the limitations on the Second Priority Representative and the Second Priority Secured Parties imposed hereby, (B) the Second Priority Representative and the Secured Parties shall be entitled to file any necessary or responsive defensive pleadings in opposition to any motion, claim, adversary proceeding or other pleading made by any person objecting to or otherwise seeking the disallowance of the claims of the Second Priority Secured Parties, including without limitation, any claim secured by the Common Collateral, if any, in each case if not otherwise in contravention of this Agreement, (C) the Second Priority Secured Parties shall be entitled to file any pleadings, objections, motions or agreements which assert rights or interests available to unsecured creditors arriving under either the Bankruptcy Code or applicable non-bankruptcy law, in each case if not otherwise in contravention of the terms of this Agreement, (D) the Second Priority Secured Parties shall be entitled to file any proof of claim and other filings and make any arguments and motions in order to preserve or protect its Liens on the Common Collateral that are, in each case, not otherwise in contravention of the terms of this Agreement, with respect to the Second Priority Obligations and the Common Collateral, (E) the Second Priority Representative or any Second Priority Secured Party

11

may exercise any of its rights or remedies with respect to the Common Collateral after the termination of the Standstill Period to the extent permitted herein, including, without limitation, Section 3.1 above, and (F) in any Insolvency Proceeding with respect to Par Piceance or the Common Collateral, the Second Priority Secured Parties shall be entitled to vote on any plan or reorganization, to the extent consistent with the provisions hereof.

(b) Prior to the First Priority Obligations Payment Date but subject to Section 5.5 hereof, if the First Priority Secured Parties receive an allowance in any Insolvency Proceeding of First Priority Obligations consisting of Post-Petition Interest, fees or expenses, then no First Priority Secured Party shall oppose or seek to challenge any claim by any Second Priority Secured Party for an allowed claim in any plan of reorganization in any Insolvency Proceeding of the Second Priority Obligations consisting of Post-Petition Interest, fees or expenses to the extent of the value of the Lien of the Second Priority Representative, on behalf of the Second Priority Secured Parties in the Common Collateral (after taking into account the value of the Lien in the Common Collateral securing the First Priority Obligations).

5.2 Relief From the Automatic Stay. The Second Priority Representative agrees, on behalf of itself and the other Second Priority Secured Parties, that none of them will seek relief from the automatic stay or from any other stay in any Insolvency Proceeding or take any action in derogation thereof, in each case in respect of any Common Collateral, without the prior written consent of the First Priority Representative (except if the First Priority Representative, on behalf of itself and the First Priority Secured Parties, seeks relief from the automatic stay to exercise its rights against the Common Collateral, then the Second Priority Representative, on behalf of itself and the other Second Priority Secured Parties, may seek limited relief from the automatic stay only to preserve its right to receive proceeds of the Common Collateral payable to it and the other Second Priority Secured Parties, as applicable, under and in accordance with this Agreement).

5.3 Avoidance Issues. If any First Priority Secured Party is required in any Insolvency Proceeding or otherwise to disgorge, turn over, or otherwise pay to the estate of any PEL Credit Party, because such amount was avoided or ordered to be paid or disgorged for any reason, including without limitation because it was found to be a fraudulent or preferential transfer, any amount (a “Recovery”), whether received as proceeds of security, enforcement of any right of set-off, or otherwise, then the First Priority Obligations shall be reinstated to the extent of such Recovery and deemed to be outstanding as if such payment had not occurred and the First Priority Obligations Payment Date shall be deemed not to have occurred. If this Agreement shall have been terminated prior to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair, or otherwise affect the obligations of the parties hereto. The Second Priority Secured Parties agree that none of them (solely in their capacity as Second Priority Secured Parties) shall be entitled to benefit from any avoidance action affecting or otherwise relating to any distribution or allocation with respect to the Common Collateral made in accordance with this Agreement, whether by preference or otherwise, it being understood and agreed that the benefit of such avoidance action otherwise allocable to them shall instead be allocated and turned over for application in accordance with the priorities set forth in this Agreement.

5.4 Asset Dispositions in an Insolvency Proceeding. Neither the Second Priority Representative nor any other Second Priority Secured Party shall, in an Insolvency Proceeding or otherwise, oppose any sale or disposition of the Common Collateral that is supported by the First Priority Secured Parties, and the Second Priority Representative and each other Second Priority Secured Party will be deemed to have consented under Section 363 of the Bankruptcy Code (and otherwise) to any sale supported by the First Priority Secured Parties; provided, that nothing in this Section 5.4 shall impair the ability of the Second Priority Secured Parties to make a credit bid pursuant to Section 363(k) of the Bankruptcy Code so long as the First Priority Obligations Payment Date occurs in connection therewith (if the First Priority Obligations Payment Date has not already occurred).

12

5.5 Separate Grants of Security and Separate Classification. Each Second Priority Secured Party acknowledges and agrees that (a) the grants of Liens pursuant to the Parent Pledge Agreement and the Comparable Second Priority Security Documents constitute two separate and distinct grants of Liens and (b) because of, among other things, their differing rights in the Common Collateral, the Second Priority Obligations are fundamentally different from the First Priority Obligations and must be separately classified in any plan of reorganization proposed or adopted in an Insolvency Proceeding. To further effectuate the intent of the parties as provided in the immediately preceding sentence, if it is held that the claims of the First Priority Secured Parties and Second Priority Secured Parties in respect of the Common Collateral constitute only one secured claim (rather than separate classes of senior and junior secured claims), then the Second Priority Secured Parties hereby acknowledge and agree that all distributions shall be made as if there were separate classes of senior and junior secured claims against Par Piceance in respect of the Common Collateral (with the effect being that, to the extent that the aggregate value of the Common Collateral is sufficient (for this purpose ignoring all claims held by the Second Priority Secured Parties), the First Priority Secured Parties shall be entitled to receive, in addition to amounts distributed to them in respect of principal, pre-petition interest, and other claims, all amounts owing in respect of Post-Petition Interest before any distribution is made in respect of the claims held by the Second Priority Secured Parties. The Second Priority Secured Parties hereby acknowledge and agree to turn over to the First Priority Secured Parties amounts otherwise received or receivable by them to the extent necessary to effectuate the intent of the preceding sentence, even if such turnover has the effect of reducing the claim or recovery of the Second Priority Secured Parties.

5.6 No Waivers of Rights of First Priority Secured Parties. Nothing contained herein shall prohibit or in any way limit the First Priority Representative or any other First Priority Secured Party from objecting in any Insolvency Proceeding or otherwise to any action taken by any Second Priority Secured Party, including the seeking by any Second Priority Secured Party of adequate protection or the asserting by any Second Priority Secured Party of any of its rights and remedies under the Second Priority Documents or otherwise.

5.7 Effectiveness in Insolvency Proceedings. This Agreement, which the parties hereto expressly acknowledge is a “subordination agreement” under section 510(a) of the Bankruptcy Code, shall be effective before, during and after the commencement of an Insolvency Proceeding.

SECTION 6. Second Priority Documents and First Priority Documents.

(a) Each of Par Piceance, PPC and the Second Priority Representative, on behalf of itself and the Second Priority Secured Parties, agrees that it shall not at any time execute or deliver any amendment or other modification to any of the Second Priority Documents (i) the effect of which is to shorten the maturity date of the Second Priority Obligations to a date that is prior to August 31, 2016, or (ii) that is otherwise inconsistent with or in violation of this Agreement. Any attempt to enter into any amendment or modification in violation of the previous sentence shall be void ab inito.

(b) Each of Par Piceance and the First Priority Representative, on behalf of itself and the First Priority Secured Parties, agrees that it shall not at any time execute or deliver any amendment or other modification to any of the First Priority Documents inconsistent with or in violation of this Agreement.

(c) In the event the First Priority Representative enters into any amendment, waiver, or consent in respect of the Parent Pledge Agreement for the purpose of adding to, or deleting from, or

13

waiving or consenting to any departures from any provisions of, the Parent Pledge Agreement or changing in any manner the rights of any parties thereunder, then such amendment, waiver, or consent shall apply automatically to the Comparable Second Priority Security Documents without the consent of or action by any Second Priority Secured Party (with all such amendments, waivers and modifications subject to the terms hereof); provided that, (i) no such amendment, waiver, or consent shall have the effect of removing assets subject to the Lien of any Comparable Second Priority Security Document, except to the extent that a release of such Lien is permitted by Section 4.2, (ii) any such amendment, waiver, or consent that materially and adversely affects the rights of the Second Priority Secured Parties and does not affect the First Priority Secured Parties in a like or similar manner shall not apply to the Comparable Second Priority Security Documents without the consent of the Second Priority Representative and (iii) notice of such amendment, waiver, or consent shall be given to the Second Priority Representative no later than 30 days after its effectiveness, provided that the failure to give such notice shall not affect the effectiveness and validity thereof.

SECTION 7. Reliance; Waivers; etc.

7.1 Reliance. The First Priority Documents are deemed to have been executed and delivered, and all extensions of credit thereunder are deemed to have been made or incurred, in reliance upon this Agreement.
