(b)Notwithstanding the foregoing provision of this Section 2.2, it is the intention of the parties hereto that the Parity Lien Secured Parties of each Series of Parity Lien Debt (and not the Parity Lien Secured Parties of any other Series of Parity Lien Debt) bear their own risk of (i) any determination by a court of competent jurisdiction that (1) any Parity Lien Obligations of such Series of Parity Lien Debt are unenforceable under applicable law or are subordinated to any other obligations, (2) any Parity Lien Obligations of such Series of Parity Lien Debt do not have a valid and perfected Lien on any of the Collateral securing any Parity Lien Obligations of any other Series of Parity Lien Debt and/or (3) any Person (other than any Parity Lien Secured Party) has a Lien on any Collateral that is senior in priority to the Lien on such Collateral securing Parity Lien Obligations of such Series of Parity Lien Debt, but junior to the Lien on such Collateral securing any Parity Lien Obligations of any other Series of Parity Lien Debt (any such Lien being referred to as an “Intervening Lien”, and any such Person being referred to as an “Intervening Creditor”), or (ii) the existence of any Collateral securing Parity Lien Obligations of any other Series of Parity Lien Debt that does not constitute Collateral with respect to Parity Lien Obligations of such Series of Parity Lien Debt (any condition referred to in clause (i) or (ii) with respect to Parity Lien Obligations of such Series of Parity Lien Debt being referred to as an “Impairment” of such Series of Parity Lien Debt). In the event an Impairment exists with respect to Parity Lien Obligations of any Series of Parity Lien Debt, the results of such Impairment shall be borne solely by the Parity Lien Secured Parties of such Series of Parity Lien Debt, and the rights of the Parity Lien Secured Parties of such Series of Parity Lien Debt (including the right to receive distributions pursuant to Section 3.4) set forth herein shall be modified to the extent necessary so that the results of such Impairment are borne solely by the Parity Lien Secured Parties of such Series of Parity Lien Debt. In furtherance of the foregoing, in the event Parity Lien Obligations of any Series of Parity Lien Debt shall be subject to an Impairment in the form of an Intervening Lien of any Intervening Creditor, the value of any Collateral or proceeds thereof that are allocated to such Intervening Creditor shall be deducted solely from the Collateral or proceeds thereof to be distributed in respect of Parity Lien Obligations of such Series of Parity Lien Debt.

Section 2.3Similar Collateral and Agreements. The parties to this Agreement agree that it is their intention that the Parity Liens be identical. In furtherance of the foregoing, the parties hereto agree that the Parity Lien Security Documents creating Liens upon Collateral securing any Parity Lien Obligation shall be in all material respects the same forms of documents (or the same documents) as the respective Notes Security Documents creating Liens on the Collateral.

Section 3.5Powers of the Collateral Trustee.

(a)The Collateral Trustee is irrevocably authorized and empowered to enter into and perform its obligations and protect, perfect, exercise and enforce its interest, rights, powers and remedies under the Parity Lien Security Documents, the Intercreditor Agreement and applicable law and in equity and to act as set forth in this Article 3 or, subject to the other provisions of this Agreement, as requested in any lawful written directions given to it from time to time in respect of any matter by an Act of Parity Lien Debtholders.

Parity Lien Obligations, and will distribute all proceeds received by it in realization thereon or from enforcement thereof solely and exclusively pursuant to the provisions of Section 3.4.

Section 3.8Additional Parity Lien Debt.

(a)The Collateral Trustee will, as trustee hereunder, perform its undertakings set forth in Section 3.1(a) with respect to any Parity Lien Obligations constituting Additional Notes or a Series of Parity Lien Debt that is issued or incurred after the date hereof; provided that:

(1)such Parity Lien Obligations are identified as Parity Lien Debt in accordance with the procedures set forth in Section 3.8(b); and

(2)except in the case of Additional Notes, the designated Parity Lien Representative identified pursuant to Section 3.8(b) signs a Collateral Trust Joinder and delivers the same to the Collateral Trustee.

(b)The Company will be permitted to designate as an additional holder of Parity Lien Debt hereunder each Person who is, or who becomes, the registered holder of Parity Lien Debt incurred by the Company or any Guarantor after the date of this Agreement in accordance with the terms of all applicable Parity Lien Documents, Priority Lien Documents and Junior Lien Documents. The Company may only effect such designation by delivering to the Collateral Trustee an Additional Parity Lien Debt Certificate that:

(1)states that the Company or other applicable Grantor intends to incur additional Parity Lien Debt (“Additional Parity Lien Debt”) that is permitted by the Credit Agreement and each applicable Parity Lien Document to be secured with a Parity Lien equally and ratably with all previously existing and future Parity Lien Debt;

(2)except in the case of Additional Notes, specifies the name, address and contact information of the Parity Lien Representative for such series of Additional Parity Lien Debt for purposes of Section 7.6;

(3)attaches as Exhibit 1 to such Additional Parity Lien Debt Certificate a Reaffirmation Agreement in substantially the form attached as Exhibit 1 to Exhibit A of this Agreement, which Reaffirmation Agreement has been duly executed by the Company and each Guarantor; and

(4)states that the Company has caused a copy of the Additional Parity Lien Debt Certificate and, except in the case of Additional Notes, the related Collateral Trust Joinder to be delivered to each then existing Parity Lien Representative.

Although the Company shall be required to deliver a copy of each Additional Parity Lien Debt Certificate and each Collateral Trust Joinder to each then existing Parity Lien Representative, the failure to so deliver a copy of the Additional Parity Lien Debt Certificate and/or Collateral Trust Joinder to any then existing Parity Lien Representative shall not affect the status of such debt as Additional Parity Lien Debt if the other requirements of this Section 3.8 are complied with. Each of the Collateral Trustee and the then existing Parity Lien Representatives shall have the right to

request that the Company provide a legal opinion or opinions of counsel (subject to customary assumptions and qualifications) as to the Additional Parity Lien Debt being secured by a valid and perfected security interest in the Collateral; provided that (i) such legal opinion or opinions need not address any collateral of a type not previously covered by any legal opinion delivered by or on behalf of the Company and (ii) nothing shall preclude such legal opinion or opinions from being delivered on a post-closing basis after the incurrence of such Additional Parity Lien Debt if permitted by the Parity Lien Representative for such Additional Parity Lien Debt. Notwithstanding the foregoing, nothing in this Agreement will be construed to allow the Company or any Guarantor to incur additional Indebtedness (including Additional Notes) unless otherwise permitted by the terms of all applicable Parity Lien Documents, Priority Lien Documents and Junior Lien Documents.

(c)With respect to any Parity Lien Obligations constituting Additional Notes or a Series of Parity Lien Debt that is issued or incurred after the date hereof, the Company and each of the Guarantors agrees to take such actions (if any) as may from time to time reasonably be requested by the Collateral Trustee, any Parity Lien Representative or any Act of Parity Lien Debtholders, and enter into such technical amendments, modifications and/or supplements to the then existing Guarantees and Parity Lien Security Documents (or execute and deliver such additional Parity Lien Security Documents) as may from time to time be reasonably requested by such Persons (including as contemplated by Section 3.8(d) below), to ensure that the Additional Notes or the other Additional Parity Lien Debt, as applicable, are secured by, and entitled to the benefits of, the Parity Lien Security Documents, and each Parity Lien Secured Party (by its acceptance of the benefits hereof) hereby agrees to, and authorizes the Collateral Trustee to enter into, any such technical amendments, modifications and/or supplements (and additional Parity Lien Security Documents). The Company and the Guarantors hereby further agree that, if there are any recording, filing or other similar fees payable in connection with any of the actions to be taken pursuant to this Section 3.8(c) or Section 3.8(d), all such amounts shall be paid by, and shall be for the account of, the Company and the Guarantors, on a joint and several basis.

(d)Without limitation of the foregoing, upon reasonable request of the Collateral Trustee, any Parity Lien Representative or any Act of Parity Lien Debtholders, each Mortgagor agrees to take the following actions with respect to any real property Collateral (including Oil and Gas Properties (as defined in the Indenture as in effect on the date hereof)) with respect to all Additional Parity Lien Debt (it being understood that any such actions may be taken following the incurrence of any such Additional Parity Lien Debt on a post-closing basis if permitted by the Parity Lien Representative for such Additional Parity Lien Debt):

(1)each applicable Mortgagor shall enter into, and deliver to the Collateral Trustee, a Mortgage modification or new Mortgage with regard to each real property subject to a Mortgage (each such property a “Mortgaged Property”), in proper form for recording in all applicable jurisdictions, in a form and substance reasonably satisfactory to the Collateral Trustee; and

(2)each applicable Mortgagor will cause to be delivered to the Collateral Trustee a local counsel opinion (subject to customary assumptions and qualifications) to the effect that the Collateral Trustee has a valid and perfected Lien with respect to each such Mortgaged Property, provided that, in the case of Additional Notes,

to the extent Mortgages have previously been recorded in the public records of the state applicable to such additional Mortgages or amendments or supplements to prior Mortgages, no such opinion shall be required unless a corresponding opinion will be delivered to the Priority Lien Agent.

The Company will deliver an Officers’ Certificate to the Collateral Trustee confirming that the foregoing conditions have been satisfied.

(c)The Collateral Trustee hereby agrees that:

(2)at any time when a Parity Lien Debt Default has occurred and is continuing, the Collateral Trustee will use reasonable efforts to deliver within three Business Days of the receipt by it of any Act of Parity Lien Debtholders pursuant to Section 4.1(a)(4), a copy of such Act of Parity Lien Debtholders to each Parity Lien Representative.

Section 4.2Delivery of Copies to Parity Lien Representatives. The Company will deliver to each Parity Lien Representative a copy of each Officers’ Certificate delivered to the Collateral Trustee pursuant to Section 4.1(b), together with copies of all documents delivered to the Collateral Trustee with such Officers’ Certificate.

Each Parity Lien Representative will endeavor, following receipt by it of the executed Officers’ Certificate and proposed release instrument(s) delivered to the Collateral Trustee pursuant to Section 4.1(b), deliver a copy of such Officers’ Certificate and proposed release instrument(s) to each registered holder of the Series of Parity Lien Debt for which it acts as Parity Lien Representative to the extent required by the applicable Parity Lien Debt Documents.

Section 4.5Release of Liens in Respect of any Series of Parity Lien Debt other than the Notes. In addition to any release pursuant to Section 4.1 hereof, as to any Series of Parity Lien Debt other than the Notes, the Collateral Trustee’s Parity Lien will no longer secure such Series of Parity Lien Debt if such Parity Lien Debt has been paid in full, all commitments to extend credit in respect of such Series of Parity Lien Debt have been terminated and all other Parity Lien Obligations related thereto that are outstanding and unpaid at the time such Series of Parity Lien Debt is paid are also paid in full, or upon written certification to that effect delivered by the applicable Parity Lien Representative to the Collateral Trustee in connection with a release under such Parity Lien Debt or the Intercreditor Agreement.

ARTICLE 5

IMMUNITIES OF THE COLLATERAL TRUSTEE

Section 5.1No Implied Duty. The Collateral Trustee will not have any fiduciary duties nor will it have responsibilities or obligations other than those expressly assumed by it in this Agreement, the other Parity Lien Security Documents and the Intercreditor Agreement. No implied covenants, functions, responsibilities, duties, obligations or liabilities, whether arising under statute, common law or otherwise, shall be read into this Agreement, the other Parity Lien Documents or the Intercreditor Agreement, or otherwise exist against the Collateral Trustee. Without limiting the generality of the foregoing sentences, the use of the term “trustee” in this Agreement with reference to the Collateral Trustee is not intended to connote any fiduciary or other implied (or express) obligations arising under trust or agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. The Collateral Trustee will not be required to take any action that is contrary to applicable law or any provision of this Agreement, the other Parity Lien Security Documents or the Intercreditor Agreement.

Section 5.2Appointment of Agents and Advisors. The Collateral Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys, accountants, appraisers or other experts or advisors selected by it in good faith as it may reasonably require and will not be responsible for any misconduct or negligence on the part of any of them.

Section 5.3Other Agreements. The Collateral Trustee has accepted its appointment as collateral trustee hereunder and is bound by the Parity Lien Security Documents executed by the Collateral Trustee as of the date of this Agreement, and the Collateral Trustee shall at the request of the Company execute additional Parity Lien Security Documents delivered to it after the date of this Agreement (including to secure Obligations arising under Additional Parity Lien Debt to the extent such Obligations are permitted to be incurred and secured under the Parity Lien Documents); provided that such additional Parity Lien Security Documents do not adversely affect the rights, privileges, benefits and immunities of the Collateral Trustee or conflict with the terms of the Intercreditor Agreement. The Collateral Trustee will not otherwise be bound by, or be held obligated by, the provisions of any credit agreement, indenture or other agreement governing Parity Lien Debt (other than this Agreement, the Indenture and the other Parity Lien Security Documents to which it is a party).

Section 5.4Solicitation of Instructions.

(a)The Collateral Trustee may at any time solicit written confirmatory instructions, in the form, including but not limited to, of an Act of Parity Lien Debtholders, an Officers’ Certificate, written instruction from Parity Lien Representatives or an order of a court of competent jurisdiction, as to any action that it may be requested or required to take, or that it may propose to take, in the performance of any of its obligations under this Agreement or the other Parity Lien Security Documents, and the Collateral Trustee will not be liable for any action it takes or omits to take in good faith in reliance on any such certificate, opinion or order. In the absence of bad faith on its part, the Collateral Trustee may rely, and will be protected in acting or refraining from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper Person. The Collateral Trustee need not investigate any fact or matter stated in the document, but, in the case of any document which is specifically required to be furnished to the Collateral Trustee pursuant to any provision hereof, the Collateral Trustee shall examine the document to determine whether it conforms to the requirements of this Agreement or the applicable Parity Lien Document (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(b)No written direction given to the Collateral Trustee by an Act of Parity Lien Debtholders that in the sole judgment of the Collateral Trustee imposes, purports to impose or might reasonably be expected to impose upon the Collateral Trustee any obligation or liability not set forth in or arising under this Agreement and the other Parity Lien Security Documents will be binding upon the Collateral Trustee unless the Collateral Trustee elects, at its sole option, to accept such direction.

(c)The Collateral Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Agreement at the request, order or direction of the Required Parity Lien Debtholders or an Act of Parity Lien Debtholders pursuant to the provisions of this Agreement, unless such holders shall have furnished to the Collateral Trustee reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby.

Section 5.5Limitation of Liability. The Collateral Trustee will not be responsible or liable for any action taken or omitted to be taken by it hereunder or under any other Parity Lien Security Document, except as determined by a court of competent jurisdiction in a final, non-appealable order or judgment to have resulted from the Collateral Trustee’s own gross negligence or willful misconduct.

Section 5.6Documents in Satisfactory Form. The Collateral Trustee will be entitled to require that all agreements, certificates, opinions, instruments and other documents at any time submitted to it, including those expressly provided for in this Agreement, be delivered to it in a form reasonably satisfactory to it. The Collateral Trustee (i) makes no representation as to the validity or adequacy of any Parity Lien Document and (ii) is not responsible for any statement in any Parity Lien Document other than its certificate of authentication and any representations and warranties specifically made by it.

Section 5.7Entitled to Rely. The Collateral Trustee may seek and rely upon, and shall be fully protected in relying upon, any judicial order or judgment, upon any advice, opinion or statement of legal counsel, independent consultants and other experts selected by it in good faith and upon any certification, instruction, notice or other writing delivered to it by the Company or any Guarantor in compliance with the provisions of this Agreement or delivered to it by any Parity Lien Representative as to the holders of Parity Lien Obligations for whom it acts, without being required to determine the authenticity thereof or the correctness of any fact stated therein or the propriety or validity of service thereof. The Collateral Trustee may act in reliance upon any instrument comporting with the provisions of this Agreement or any signature believed by it in good faith to be genuine and may assume that any Person purporting to give notice or receipt or advice or make any statement or execute any document in connection with the provisions hereof or the other Parity Lien Security Documents has been duly authorized to do so. To the extent an Officers’ Certificate or Opinion of Counsel is required or permitted under this Agreement to be delivered to the Collateral Trustee in respect of any matter, the Collateral Trustee may rely conclusively on an Officers’ Certificate or Opinion of Counsel as to such matter and such Officers’ Certificate or Opinion of Counsel shall be full warranty and protection to the Collateral Trustee for any action taken, suffered or omitted by it under the provisions of this Agreement and the other Parity Lien Security Documents. The Collateral Trustee (a) shall not be responsible to any Parity Lien Secured Party for any recitals, statements, information, representations or warranties of any other Person contained herein, in the Parity Lien Documents or in any document, certificate or other writing delivered in connection herewith or therewith or for the execution, effectiveness, genuineness, validity, enforceability, collectability, priority or sufficiency of this Agreement, the Parity Lien Documents or the financial condition of the Company, the Guarantors or any of them and (b) shall not be required to ascertain or inquire as to the performance or observation of any of the terms, covenants or conditions of this Agreement or any Parity Lien Document.

Section 5.8Parity Lien Debt Default. The Collateral Trustee will not be required to inquire as to the occurrence or absence of any Parity Lien Debt Default and will not be affected by or required to act upon any notice or knowledge as to the occurrence of any Parity Lien Debt Default unless and until it is directed by an Act of Parity Lien Debtholders.

Section 5.9Actions by Collateral Trustee. As to any matter not expressly provided for by this Agreement or the other Parity Lien Security Documents, the Collateral Trustee will act or refrain from acting as directed by an Act of Parity Lien Debtholders and will be fully protected if it does so, and any action taken, suffered or omitted pursuant hereto or thereto shall be binding on the holders of Parity Lien Debt.

Section 5.10Security or Indemnity in favor of the Collateral Trustee. The Collateral Trustee will not be required to advance or expend any funds or otherwise incur any financial liability in the performance of its duties or the exercise of its powers or rights hereunder unless it has been provided with reasonable security or indemnity satisfactory to it against any and all loss, liability or expense which may be incurred by it by reason of taking or continuing to take such action.

Section 5.11Rights of the Collateral Trustee. In the event of any conflict between any terms and provisions set forth in this Agreement and those set forth in any other Parity Lien Security Document, the terms and provisions of this Agreement shall supersede and control the terms and provisions of such other Parity Lien Security Document. In the event there is any bona fide, good faith disagreement between the other parties to this Agreement or any of the other Parity Lien Security Documents resulting in adverse claims being made in connection with Collateral held by the Collateral Trustee and the terms of this Agreement or any of the other Parity Lien Security Documents do not unambiguously mandate the action the Collateral Trustee is to take or not to take in connection therewith under the circumstances then existing, or the Collateral Trustee is in doubt as to what action it is required to take or not to take hereunder or under the other Parity Lien Security Documents, it will be entitled to refrain from taking any action (and will incur no liability for doing so) until directed otherwise in writing by a request signed jointly by the parties hereto entitled to give such direction or by order of a court of competent jurisdiction.

Section 5.12Limitations on Duty of Collateral Trustee in Respect of Collateral.

(a)Beyond the exercise of reasonable care in the custody of Collateral in its possession, the Collateral Trustee will have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Collateral Trustee will not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on the Collateral; provided that, notwithstanding the foregoing, the Collateral Trustee will have the right but not the obligation to execute, file or record UCC-3 continuation statements and other documents and instruments to preserve, protect or perfect the security interests granted to the Collateral Trustee (subject to the priorities set forth herein) if it shall receive a specific written request to execute, file or record the particular continuation statement or other specific document or instrument by any Parity Lien Representative. The Collateral Trustee shall deliver to each other Parity Lien Representative a copy of any such written request. The Collateral Trustee will be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property, and the Collateral Trustee will not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Trustee in good faith.

(b)Except as provided in Section 5.12(a), the Collateral Trustee will not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, for the validity or sufficiency of the Collateral or any agreement, annex, schedule, exhibit, description or assignment contained therein, for the validity of the title of any Mortgagor to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Collateral Trustee hereby disclaims any representation or warranty to the current and future holders of the Parity Lien Obligations concerning the perfection of the security interests granted to it or in the value of any Collateral. The Collateral Trustee shall not be under any obligation to the Trustee or any holder

of Parity Lien Debt to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this or any other Parity Lien Security Document or the Intercreditor Agreement or to inspect the properties, books or records of the Company or any Guarantor.

Section 5.13Assumption of Rights, Not Assumption of Duties. Notwithstanding anything to the contrary contained herein:

(1)each of the parties thereto will remain liable under each of the Parity Lien Security Documents (other than this Agreement) to the extent set forth therein to perform all of their respective duties and obligations thereunder to the same extent as if this Agreement had not been executed;

(2)the exercise by the Collateral Trustee of any of its rights, remedies or powers hereunder will not release such parties from any of their respective duties or obligations under the other Parity Lien Security Documents; and

(3)the Collateral Trustee will not be obligated to perform any of the obligations or duties of the Company, any Grantor or any other party to the Parity Lien Security Documents (other than the Collateral Trustee).

Section 5.14No Liability for Clean Up of Hazardous Materials. In the event that the Collateral Trustee is required to acquire title to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any fiduciary or trust obligation for the benefit of another, which in the Collateral Trustee’s sole discretion may cause the Collateral Trustee to be considered an “owner or operator” under any environmental laws or otherwise cause the Collateral Trustee to incur, or be exposed to, any environmental liability or any liability under any other federal, state or local law, the Collateral Trustee reserves the right, instead of taking such action, either to resign as Collateral Trustee (in accordance with Article 6) or to arrange for the transfer of the title or control of the asset to a court appointed receiver. The Collateral Trustee will not be liable to any Person for any environmental liability or any environmental claims or contribution actions under any federal, state or local law, rule or regulation by reason of the Collateral Trustee’s actions and conduct as authorized, empowered and directed hereunder or relating to any kind of discharge or release or threatened discharge or release of any hazardous materials into the environment.

Section 5.15Other Relationships with the Company or Guarantors. Wilmington Trust, National Association and its Affiliates (and any other bank or trust company serving as successor Collateral Trustee and its Affiliates) may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with the Company or any Guarantor and its Affiliates as though it was not the Collateral Trustee hereunder and without notice to or consent of the Parity Lien Representatives. The Parity Lien Representatives and the Parity Lien Secured Parties acknowledge that, pursuant to such activities, Wilmington Trust, National Association or its Affiliates (and any other bank or trust company serving as successor Collateral Trustee and its Affiliates) may receive information regarding the Company or any Guarantor or its Affiliates (including information that may be subject to confidentiality obligations in favor of

the Company, such Guarantor or such Affiliate) and acknowledge that (i) such knowledge is not imputed to the Collateral Trustee and (ii) the Collateral Trustee shall not be under any obligation to provide such information to the Parity Lien Secured Parties. Nothing herein shall impose or imply any obligation on the part of Wilmington Trust, National Association (or any other bank or trust company serving as successor Collateral Trustee) to advance funds.

Section 5.16No Liability for Interest. The Collateral Trustee shall not be liable for interest or investment income on any money or securities received by it, except as the Collateral Trustee may agree in writing with the Company.

Section 5.17No Duty to Acquire or Disseminate Information. The Collateral Trustee shall not be required to keep itself informed as to the performance or observance by the Company or any Guarantor of any of its obligations under this Agreement, any Parity Lien Document or any other document referred to or provided for herein or therein. Except for notices, reports and other documents and information expressly required to be furnished to any Parity Lien Secured Party by the Collateral Trustee hereunder, the Collateral Trustee shall have no duty or responsibility to provide any Parity Lien Secured Party with any credit or other information concerning the affairs, financial condition or business of the Company or any Guarantor that may come into the possession of the Collateral Trustee or any of its Affiliates.

(2)having a combined capital and surplus of at least $250,000,000.

Section 6.3Succession. When the Person so appointed as successor Collateral Trustee accepts such appointment:

ARTICLE 7

MISCELLANEOUS PROVISIONS

Section 7.1Amendment.

(a)Except as provided in the Intercreditor Agreement, no amendment or supplement to the provisions of any Parity Lien Security Document will be effective without the approval of the Collateral Trustee acting as directed by an Act of Parity Lien Debtholders, except that:

(1)any amendment or supplement that has the effect solely of:

(A)adding or maintaining Collateral, securing additional Parity Lien Debt that was otherwise permitted by the terms of the Parity Lien Documents, Priority Lien Documents and Junior Lien Documents to be secured by the Collateral or preserving, perfecting or establishing the Liens thereon or the rights of the Collateral Trustee therein;

(B)providing for the assumption of a Grantor’s obligations under any Parity Lien Document in the case of a merger or consolidation or sale

of all or substantially all of the properties or assets of a Grantor to the extent permitted by the terms of the Indenture and the other Parity Lien Documents, as applicable; or

(C)to cure any ambiguity.

will become effective when executed and delivered by the Company or any other applicable Grantor party thereto and, if required for effectiveness pursuant to its terms, the Collateral Trustee;

(2)no amendment or supplement that reduces, impairs or adversely affects the right of any Parity Lien Secured Party:

(A)to vote its outstanding Parity Lien Debt as to any matter described as subject to an Act of Parity Lien Debtholders or direction by the Required Parity Lien Debtholders (or amends the provisions of this clause (2) or the definition of “Act of Parity Lien Debtholders” or “Required Parity Lien Debtholders”),

(C)to require that Liens securing Parity Lien Obligations be released only as set forth in the provisions described in Sections 4.1, 4.4 or 4.5,

will become effective without the consent of the requisite percentage or number of holders of each Series of Parity Lien Debt adversely affected thereby under the applicable Parity Lien Document; and

(3)no amendment or supplement that imposes any obligation upon the Collateral Trustee or any Parity Lien Representative or adversely affects the rights of the Collateral Trustee or any Parity Lien Representative, respectively, in its individual capacity as such will become effective without the consent of the Collateral Trustee or such Parity Lien Representative, respectively.

Any amendment or supplement to the provisions of the Parity Lien Security Documents that releases Collateral will be effective only in accordance with the requirements set forth in the applicable Parity Lien Document referenced in Sections 4.1 or 4.5 hereof. Any amendment or supplement that results in the Collateral Trustee’s Liens upon the Collateral no longer securing the Notes and the other Obligations under the Indenture and other Note Documents may only be effected in accordance with Section 4.4 hereof.

(b)Notwithstanding anything to the contrary contained in Section 7.1(a) but subject to Sections 7.1(a)(2) and 7.1(a)(3):

(1)any Mortgage or other Parity Lien Security Document may be amended or supplemented with the approval of the Collateral Trustee acting as directed in writing by the Required Parity Lien Debtholders, unless such amendment or

supplement would not be permitted under the terms of this Agreement, the Intercreditor Agreement or any Priority Lien Documents;

(2)any amendment or waiver of, or any consent under, any provision of any security document that secures Priority Lien Obligations will apply automatically to any comparable provision of any comparable Parity Lien Security Document without the consent of or notice to any holder of Parity Lien Obligations and without any action by the Company or any Grantor or any holder of Notes or other Parity Lien Obligations provided, however, that (x) no such amendment, waiver or consent shall (i) release or remove assets subject to the Lien securing any Parity Lien Obligations, except to the extent such release is expressly required by the Intercreditor Agreement, (ii) materially adversely affect the rights or interests of the holders of Parity Lien Obligations in the Collateral and not the holders of Priority Lien Obligations in a like or similar manner or (iii) increase the obligations of or impose additional duties on the Collateral Trustee or any Parity Lien Representative that are adverse to it, without its prior written consent and (y) written notice of such amendment, waiver or consent shall have been given to the Collateral Trustee within 10 Business Days after the effectiveness of such amendment, waiver or consent; and

(3)any Mortgage or other Parity Lien Security Document, the Intercreditor Agreement and this Agreement may be amended or supplemented with the approval of the Collateral Trustee (but without the consent of or notice to any holder of Parity Lien Obligations and without any action by any holder of Notes or other Parity Lien Obligations), (i) to cure any ambiguity, defect or inconsistency, (ii) as may be necessary or advisable to preserve and confirm the relative priorities of the Secured Debt Documents as such priorities are contemplated by and set forth in the Intercreditor Agreement or (iii) solely with respect to a Mortgage or other Parity Lien Security Document, to make other changes that do not have an adverse effect on the validity of the Lien created thereby.

(c)The Collateral Trustee will not enter into any amendment or supplement unless it has received an Officers’ Certificate to the effect that such amendment or supplement will not result in a breach of any provision or covenant contained in this Agreement, the Intercreditor Agreement or any of the Parity Lien Documents. Prior to executing any amendment or supplement pursuant to this Section 7.1, the Collateral Trustee will be entitled to receive an Opinion of Counsel of the Company to the effect that the execution of such document is authorized or permitted hereunder, and with respect to amendments adding Collateral, an Opinion of Counsel of the Company addressing customary creation and perfection, and if such additional Collateral consists of equity interests of any Person which equity interests constitute certificated securities, priority matters with respect to such additional Collateral (which opinion may be subject to customary assumptions and qualifications).

(d)Upon request of the Collateral Trustee, each Parity Lien Representative shall provide written notice to the Collateral Trustee of the aggregate principal amount of outstanding Parity Lien Debt for which it is the Parity Lien Representative.

Section 7.2Voting. In connection with any matter under this Agreement requiring a vote of holders of Parity Lien Debt, each Series of Parity Lien Debt will cast its votes in accordance with the Parity Lien Documents governing such Series of Parity Lien Debt. The amount of Parity Lien Debt to be voted by a Series of Parity Lien Debt will equal (1) the aggregate principal amount of Parity Lien Debt held by such Series of Parity Lien Debt (including outstanding letters of credit whether or not then available or drawn), plus (2) other than in connection with an exercise of remedies, the aggregate unfunded commitments to extend credit which, when funded, would constitute Indebtedness of such Series of Parity Lien Debt (to the extent such unfunded commitments have not been terminated by the holders of such Series of Parity Lien Debt). Following and in accordance with the outcome of the applicable vote under its Parity Lien Documents, the Parity Lien Representative of each Series of Parity Lien Debt will vote the total amount of Parity Lien Debt under that Series of Parity Lien Debt as a block in respect of any vote under this Agreement. In connection with this Section 7.2, the Collateral Trustee may conclusively rely upon information supplied by the relevant Parity Lien Representative as to the amounts of Parity Lien Debt held by each Series of Parity Lien Debt.

Section 7.3Further Assurances.

(a)The Company and each of the Guarantors will do or cause to be done all acts and things that may be required, or that the Collateral Trustee from time to time may reasonably request, to assure and confirm that the Collateral Trustee holds, for the benefit of the holders of Parity Lien Obligations, duly created Liens upon the Collateral (including any property or assets constituting Collateral that are acquired or otherwise become, or are required by any Parity Lien Document to become, Collateral after the date hereof), in each case, as contemplated by, and, to the extent required to be perfected, perfected, and enforceable Liens, with the Lien priority required under the Parity Lien Documents. In connection with any merger or consolidation of any Grantor, such Grantor shall take such action as may be reasonably necessary to cause any newly acquired property and assets to be made subject to the Parity Liens in the manner and to the extent required under the Parity Lien Security Documents.

(b)Upon the reasonable request of the Collateral Trustee or any Parity Lien Representative at any time and from time to time, each of the Company and the other Grantors will promptly execute, acknowledge and deliver such security documents, instruments, certificates, notices and other documents, and take such other actions as may be reasonably required, or that the Collateral Trustee may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Parity Lien Documents for the benefit of Parity Lien Secured Parties; provided that no such security document, instrument or other document shall contain provisions that are materially more burdensome upon the Grantors than the Parity Lien Documents executed and delivered (or required to be executed and delivered promptly after the date hereof) by the Grantors in connection with the issuance of the Initial Notes.

(c)From and after the date hereof, the Company shall, or shall cause the applicable Guarantor to, deliver such documents and take such actions as are required by Article 11 of the Indenture.

(d)Upon the request of the Collateral Trustee, the Company and the Guarantors will permit the Collateral Trustee or any of its agents or representatives, at reasonable times and intervals upon reasonable prior notice, to visit their offices and sites and inspect any of the Collateral and to discuss matters relating to the Collateral with their respective officers and independent public accountants. The Company and the Guarantors shall, at any reasonable time and from time to time upon reasonable prior notice, permit the Collateral Trustee or any of its agents or representatives to examine and make copies of and abstracts from the records and books of account of the Company and the Guarantors and their Subsidiaries, all at the Company’s expense.

(e)Notwithstanding anything to the contrary contained herein or in any other Parity Lien Document, to the extent that the Company or any Guarantor delivers Mortgages or amendments or supplements to prior Mortgages naming the Collateral Trustee, as mortgagee or beneficiary pursuant to this Section 7.3 or any corresponding provision of any Parity Lien Document, no local counsel opinion or opinions to the effect that the Collateral Trustee has a valid and perfected Lien with respect to such Mortgaged Property (subject to customary assumptions and qualifications) will be required to be delivered to the extent Mortgages have previously been recorded in the public records of the state applicable to such additional Mortgages or amendments or supplements to prior Mortgages, unless a corresponding opinion has been or will be delivered to the Priority Lien Agent.

Section 7.4Successors and Assigns.

(a)Except as provided in Section 5.2 and 6.1 through 6.4, the Collateral Trustee may not, in its capacity as such, delegate any of its duties or assign any of its rights hereunder, and any attempted delegation or assignment of any such duties or rights will be null and void. All obligations of the Collateral Trustee hereunder will inure to the sole and exclusive benefit of, and be enforceable by, each Parity Lien Representative and each present and future holder of Parity Lien Obligations, each of whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns.

(b)Neither the Company nor any Guarantor may delegate any of its duties or assign any of its rights hereunder, and any attempted delegation or assignment of any such duties or rights will be null and void. All obligations of the Company and the Guarantors hereunder will inure to the sole and exclusive benefit of, and be enforceable by, the Collateral Trustee, each Parity Lien Representative and each present and future holder of Parity Lien Obligations, each of whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns.

Section 7.5Delay and Waiver. No failure to exercise, no course of dealing with respect to the exercise of, and no delay in exercising, any right, power or remedy arising under this Agreement or any of the other Parity Lien Security Documents will impair any such right, power or remedy or operate as a waiver thereof. No single or partial exercise of any such right, power or remedy will preclude any other or future exercise thereof or the exercise of any other right, power or remedy. The remedies herein are cumulative and are not exclusive of any remedies provided by law.

THIS INDEMNITY COVERS ORDINARY NEGLIGENCE OF ANY OF THE FOREGOING PARTIES.

(b)All amounts due under this Section 7.9 will be payable promptly upon written demand.

(c)To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth in Section 7.9(a) may be unenforceable in whole or in part because they violate any law or public policy, each of the Grantors will contribute the maximum portion that it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all Indemnified Liabilities incurred by Indemnitees or any of them.

(d)No Grantor will ever assert any claim against any Indemnitee, on any theory of liability, for any lost profits or special, indirect or consequential damages or (to the fullest extent a claim for punitive damages may lawfully be waived) any punitive damages arising out of, in connection with, or as a result of, this Agreement or any other Parity Lien Document or any agreement or instrument or transaction contemplated hereby or relating in any

Section 7.16Counterparts, Electronic Signatures. This Agreement may be executed in any number of counterparts (including by facsimile), each of which when so executed and delivered will be deemed an original, but all such counterparts together will constitute but one and the same instrument. The parties hereto may sign this Agreement and any Collateral Trust Joinder and transmit the executed copy by electronic means, including facsimile or noneditable.pdf files. The electronic copy of the executed Agreement and any Collateral Trust Joinder is and shall be deemed an original signature.

Section 7.17Effectiveness. This Agreement will become effective upon the execution of a counterpart hereof by each of the parties hereto and receipt by each party of written notification of such execution and written or telephonic authorization of delivery thereof.

Section 7.18Grantors and Additional Grantors. Each Grantor represents and warrants that it has duly executed and delivered this Agreement. The Company will cause each Person that hereafter becomes a Grantor or is required by any Parity Lien Document to become a party to this Agreement to become a party to this Agreement, for all purposes of this Agreement, by causing such Person to execute and deliver to the Collateral Trustee a Collateral Trust Joinder, whereupon such Person will be bound by the terms hereof to the same extent as if it had executed and delivered this Agreement as of the date hereof. The Company shall promptly provide each Parity Lien Representative with a copy of each Collateral Trust Joinder executed and delivered pursuant to this Section 7.18; provided that the failure to so deliver a copy of the Collateral Trust Joinder to any then existing Parity Lien Representative shall not affect the inclusion of such Person as a Grantor if the other requirements of this Section 7.18 are complied with.

Section 7.19Insolvency. This Agreement will be applicable both before and after the commencement of any Insolvency or Liquidation Proceeding by or against any Grantor. The relative rights, as provided for in this Agreement, will continue after the commencement of any such Insolvency or Liquidation Proceeding on the same basis as prior to the date of the commencement of any such case, as provided in this Agreement.

Section 7.20Rights and Immunities of Parity Lien Representatives. The Trustee and the Collateral Trustee will be entitled, to the extent applicable to such entity, to all of the rights, protections, immunities and indemnities set forth in the Indenture and any future Parity Lien Representative will be entitled to all of the rights, protections, immunities and indemnities set forth in the credit agreement, indenture or other agreement governing the applicable Parity Lien Debt with respect to which such Person will act as representative, in each case as if specifically set forth herein. In no event will any Parity Lien Representative be liable for any act or omission on the part of the Grantors or the Collateral Trustee hereunder.

Section 7.21Intercreditor Agreement. Each Person that is secured hereunder, by accepting the benefits of the security provided hereby, (i) consents (or is deemed to consent), to the subordination of Liens in favor of the Collateral Trustee as provided for in the Intercreditor Agreement, (ii) agrees (or is deemed to agree) that it will be bound by, and will take no actions contrary to, the provisions of the Intercreditor Agreement, and (iii) authorizes (or is deemed to

authorize) and instructs (or is deemed to instruct) the Collateral Trustee on behalf of such Person to enter into, and perform under, the Intercreditor Agreement as “Second Lien Collateral Trustee” (as defined in the Intercreditor Agreement). The Collateral Trustee agrees to enter into any amendments or joinders to the Intercreditor Agreement, without the consent of any holder of Parity Lien Debt or the Parity Lien Representatives, to add additional Indebtedness as Priority Lien Debt, Parity Lien Debt or Junior Lien Debt (to the extent permitted to be incurred and secured by the applicable Secured Debt Documents) and add other parties (or any authorized agent or trustee therefor) holding such Indebtedness thereto and to establish that the Lien on any Collateral securing such Indebtedness ranks equally with the Liens on such Collateral securing the other Priority Lien Debt, Parity Lien Debt or Junior Lien Debt, as applicable, then outstanding. The foregoing provisions are intended as an inducement to the lenders under the Credit Agreement to extend credit to the Company, as the borrower under the Credit Agreement, and such lenders are intended third party beneficiaries of this provision and the provisions of the Intercreditor Agreement. Notwithstanding anything to the contrary contained herein, to the extent that any Lien on any Collateral is perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of the Priority Lien Agent, or of agents or bailees of the Priority Lien Agent, the perfection actions and related deliverables described in this Agreement or the other Parity Lien Security Documents shall not be required.

Section 7.22Force Majeure. The Collateral Trustee shall not be liable for delays or failures in performance resulting from acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental regulations superimposed after the fact, fire, communication line failures, computer viruses, power failures, earthquakes or other disasters or similar acts beyond its control.

Section 7.23Representations and Warranties. The Collateral Trustee, the Company, each Guarantor and each Parity Lien Representative represents and warrants to the others as of the date hereof (or, in the case of any Parity Lien Representative that becomes a party hereto after the date hereof, on the date that it becomes party hereto), that: (a) neither the execution and delivery of this Agreement nor its performance of or compliance with the terms and provisions hereof will conflict with, or result in a breach of the terms, conditions, or provisions of, or constitute a default under, any other agreement to which it is now subject, which conflict, breach or default could reasonably be expected to have a Material Adverse Effect (as defined in the Credit Agreement as in effect on the date hereof); (b) it has all requisite authority to execute, deliver and perform its obligations under this Agreement; and (c) this Agreement constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, subject only to applicable bankruptcy, insolvency or similar laws and general principles of equity, regardless of whether considered in a proceeding in equity or at law.

Section 7.24Additional Persons Bound Hereby. Each Parity Lien Secured Party (other than the Parity Lien Representative) and each holder of any Parity Lien Debt (other than the Parity Lien Representative) agrees, by virtue of becoming a Parity Lien Secured Party or a holder of any Parity Lien Debt, as applicable, that it shall be bound by the terms of this Agreement as if it were a party hereto.

IN WITNESS WHEREOF, the parties hereto have caused this Collateral Trust Agreement to be executed by their respective officers or representatives as of the day and year first above written.
