Notwithstanding the foregoing, if at any time all of the following conditions have been satisfied:
(1)    all Liens securing the Parity Lien Obligations have been released as provided in Section 4.1;
(2)    the Collateral Trustee holds no other property in trust as part of the Trust Estate;
(3)    no monetary obligation (other than indemnification and other contingent obligations not then due and payable and letters of credit that have been cash collateralized at the lower of (A) 105% of the aggregate undrawn amount and (B) the percentage of the aggregate undrawn amount required for release of Liens under the terms of the applicable Parity Lien Documents) is outstanding and payable under this Agreement to the Collateral Trustee or any of its co-trustees or agents (whether in an individual or representative capacity); and
(4)    the Company delivers to the Collateral Trustee an Officers’ Certificate stating that all Parity Liens of the Collateral Trustee have been released in compliance with all applicable provisions of the Parity Lien Documents and that the Grantors are not required by any Parity Lien Document to grant any Parity Lien upon any property, 
then the Trust Estate arising hereunder will terminate, except that all provisions set forth in Sections 7.8 and 7.9 that are enforceable by the Collateral Trustee or any of its co-trustees or agents (whether in an individual or representative capacity) will remain enforceable in accordance with their terms.
The parties further declare and covenant that the Trust Estate will be held and distributed by the Collateral Trustee subject to the further agreements herein.
Section 2.2    Collateral Shared Equally and Ratably. The parties to this Agreement agree that the payment and satisfaction of all of the Parity Lien Obligations will be secured equally and ratably by the Parity Lien established in favor of the Collateral Trustee for the benefit of the Parity Lien Secured Parties, notwithstanding the time of incurrence of any Parity Lien Obligations or time or method of creation or perfection of any Parity Liens securing such Parity Lien Obligations.
Section 2.3    Similar 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 (other than the Notes Security Documents) shall be in all material respects the same forms of documents as the respective Notes Security Documents creating Liens on the Collateral.

(d)    Notwithstanding anything to the contrary contained in this Agreement, neither the Company nor any of its Affiliates may serve as Collateral Trustee.
Section 3.2    Release or Subordination of Liens. The Collateral Trustee will not release or subordinate any Lien of the Collateral Trustee or consent to the release or subordination of any Lien of the Collateral Trustee, except:
(a)    as directed by an Act of Parity Lien Debtholders accompanied by an Officers’ Certificate to the effect that the release or subordination was permitted by each applicable Parity Lien Document and otherwise setting forth the requirements of Section 4.1(b)(1) and 4.1(b)(2);
(b)    as required by Article 4;

If the Collateral Trustee at any time receives written notice from a Parity Lien Representative stating that any event has occurred that constitutes a default under any Parity Lien Document entitling the Collateral Trustee to foreclose upon, collect or otherwise enforce its Liens under the Parity Lien Security Documents, the Collateral Trustee will promptly deliver written notice thereof to each Parity Lien Representative. Thereafter, the Collateral Trustee may await direction by an Act of Parity Lien Debtholders and, subject to the terms of the Intercreditor Agreement, will act, or decline to act, as directed by an Act of Parity Lien Debtholders, in the exercise and enforcement of the Collateral Trustee’s interests, rights, powers and remedies in respect of the Collateral or under the Parity Lien Security Documents or applicable law and, following the initiation of such exercise of remedies, the Collateral Trustee will act, or decline to act, with respect to the manner of such exercise of remedies as directed by an Act of Parity Lien Debtholders. 
Section 3.4    Application of Proceeds.
(a)    Subject to the terms of the Intercreditor Agreement, the Collateral Trustee will apply the proceeds of any collection, sale, foreclosure or other realization upon, or exercise of any right or remedy with respect to, any Collateral and the proceeds of any title insurance or other insurance policy required under any Parity Lien Document or otherwise covering the Collateral, and any condemnation proceeds with respect to the Collateral, in the following order of application:
FIRST, to the payment of all amounts payable under this Agreement on account of the Collateral Trustee’s fees and any reasonable legal fees, costs and expenses or other liabilities of any kind incurred by the Collateral Trustee or any co-trustee or agent of the Collateral Trustee in connection with any Parity Lien Security Document (including, but not limited to, indemnification obligations);
SECOND, to the respective Parity Lien Representatives equally and ratably for application to the payment of all outstanding Parity Lien Debt and any other Parity Lien Obligations that are then due and payable in such order as may be provided in the Parity Lien Documents in an amount sufficient to pay in full in cash all outstanding Parity Lien Debt and all other Parity Lien Obligations that are then due and payable (including, to the extent legally permitted, all interest accrued thereon after the commencement of any Insolvency or Liquidation Proceeding at the rate, including any applicable post-default rate, specified in the Parity Lien Documents, even if such interest is not enforceable, allowable or allowed as a claim in such proceeding), and including the discharge or cash collateralization (at the lower of (1) 105% of the aggregate undrawn amount and (2) the percentage of the aggregate undrawn amount required for release of Liens under the terms of the applicable Parity Lien Document) of all outstanding letters of credit constituting Parity Lien Debt;
THIRD, to the repayment of Indebtedness and other Obligations secured by a permitted Junior Lien on the Collateral sold or realized upon; and
FOURTH, any surplus remaining after the payment in full in cash of the amounts described in the preceding clauses will be paid to the Company or the applicable Subsidiary Guarantor, as the case may be, and as directed in writing by the Company, its successors or assigns, or as a court of competent jurisdiction may direct.
(b)    This Section 3.4 is intended for the benefit of, and will be enforceable as a third party beneficiary by, each present and future holder of Parity Lien Obligations, each present and future Parity Lien Representative and the Collateral Trustee as holder of Parity Liens. The Parity Lien Representative of each future Series of Parity Lien Debt will be required to deliver a Collateral Trust Joinder including an Additional Secured Debt Designation as provided in Section 3.8 at the time of incurrence of such Series of Parity Lien Debt (it being understood that the Trustee shall be the Parity Lien Representative of the holders of the Initial Notes and any Additional Notes, and no Collateral Trust Joinder shall be required in connection with an issuance of Additional Notes).
(c)    In connection with the application of proceeds pursuant to Section 3.4(a), except as otherwise directed by an Act of Parity Lien Debtholders, the Collateral Trustee may (but shall not be obligated to) sell any non-cash proceeds for cash prior to the application of the proceeds thereof.
(d)    In making the determinations and allocations in accordance with Section 3.4(a), the Collateral Trustee may conclusively rely upon information supplied by the relevant Parity Lien Representative as to the amounts of unpaid principal and interest and other amounts outstanding with respect to such Parity Lien Representative’s respective Parity Lien Debt and any other applicable Parity Lien Obligations, and if such Parity Lien Representative does not provide such information to the Collateral Trustee, then the Collateral Trustee may conclusively rely upon such information provided by the Company.
Section 3.5    Powers of the Collateral Trustee.
(a)    Subject to the terms and conditions of the Intercreditor Agreement, 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 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.
(b)    No Parity Lien Representative or holder of Parity Lien Obligations (other than, subject to Section 5.5, the Collateral Trustee) will have any liability whatsoever for any act or omission of the Collateral Trustee, and the Collateral Trustee will have no liability whatsoever for any act or omission of any Parity Lien Representative or any holder of Parity Lien Obligations.
Section 3.6    Documents and Communications. The Grantors will permit each Parity Lien Representative and each holder of Parity Lien Obligations upon reasonable written notice and at reasonable times from time to time to inspect and copy, at the cost and expense of the party requesting such copies, any and all Parity Lien Security Documents and other documents, notices, certificates, instructions or communications provided by the Company or any Grantor to the Collateral Trustee in its capacity as such.
Section 3.7    For Sole and Exclusive Benefit of Holders of Parity Lien Obligations. The Collateral Trustee will accept, hold, administer and enforce all Liens on the Collateral at any time transferred or delivered to it and all other interests, rights, powers and remedies at any time granted to or enforceable by the Collateral Trustee and all other property of the Trust Estate solely and exclusively for the benefit of the present and future holders of present and future 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 3.8    Additional Parity Lien Debt.
(a)    The Collateral Trustee will, as collateral 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 to the extent 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 Subsidiary Guarantor after the date of this Agreement in accordance with the terms of all applicable Parity 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 Subsidiary Guarantor; and  
(4)    states that the Company has caused a copy of the Additional Parity Lien Debt Certificate and 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 Subsidiary Guarantor to incur additional Indebtedness (including Additional Notes) unless otherwise permitted by the terms of the Credit Agreement and all applicable Parity 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 Subsidiary Guarantors agrees to take such actions (if any) as may from time to time reasonably be requested by the Collateral Trustee or any Parity Lien Representative or pursuant to 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 clause (d) below), to ensure that the Additional Notes or the other Additional Parity Lien Debt, as applicable, is 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 each Subsidiary Guarantor hereby further agrees 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 respective Subsidiary Guarantors, on a joint and several basis.
(d)    Without limitation of the foregoing, upon reasonable request of the Collateral Trustee or any Parity Lien Representative or pursuant to any Act of Parity Lien Debtholders, each Grantor agrees to take the following actions with respect to any 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 Grantor shall enter into, and deliver to the Collateral Trustee a mortgage modification or new mortgage or deed of trust with regard to any Collateral subject to a mortgage or deed of trust (each such mortgage or deed of trust, as modified, a “Mortgage” and each such property constituting Collateral a “Mortgaged Property”), in proper form for recording in all applicable jurisdictions;
(2)    each applicable Grantor will cause to be delivered 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 that Mortgages have previously been recorded in the public records of the counties to which such additional Mortgage or amendments or supplements to any such existing Mortgages, no opinion shall be required unless a corresponding opinion will be required to be delivered to the Priority Lien Agent, and all opinion requirements shall be subject to any such opinion requirements set forth in the applicable Parity Lien Documents; 
(3)    each applicable Grantor will cause a title company to have delivered to the Collateral Trustee an endorsement to each title insurance policy for any real property Collateral (excluding Oil and Gas Properties), if any, then in effect for the benefit of the Parity Lien Secured Parties, date down(s) or other evidence (which may include a new title insurance policy) (each such delivery, a “Title Datedown Product”), in each case insuring that (i) validity, enforceability and the priority of the Liens of the applicable Mortgage(s) as security for the Parity Lien Obligations has not changed and, if a new Mortgage is entered into, that the Lien of such new Mortgage securing the Parity Lien Debt then being incurred shall be enforceable and have the same priority as any existing Mortgage securing then existing Parity Lien Obligations, (ii) since the later of the original date of such title insurance product and the date of the Title Datedown Product delivered most recently prior to (and not in connection with) such Additional Parity Lien Debt, there has been no change in the condition of title and (iii) there are no intervening liens or encumbrances which may then or thereafter take priority over the Lien of the applicable Mortgage(s), in each case other than with respect to Liens permitted by each Parity Lien Document; and
(4)    the Grantors shall deliver to the approved title company, the Collateral Trustee and/or all other relevant third parties all other items reasonably necessary to record each such Mortgage, to issue a Title Datedown Product and to create, perfect or preserve the validity, enforceability and priority of the Lien of the mortgage(s) as set forth above and contemplated hereby and by the Parity Lien Documents.
The Company will deliver an Officers’ Certificate to the Collateral Trustee confirming that the foregoing conditions have been satisfied.

(4)    the proposed instrument or instruments releasing such Lien as to such property in recordable form, if applicable;

(h)    The Collateral Trustee hereby agrees that:
(5)    in the case of any release pursuant to Section 4.1(a)(3), if the terms of any such sale, transfer or other disposition require the payment of the purchase price to be contemporaneous with the delivery of the applicable release, then, subject to the Intercreditor Agreement and at the written request of and at the expense of the Company or other applicable Grantor, the Collateral Trustee will either (A) be present at and deliver the release at the closing of such transaction or (B) deliver the release under customary escrow arrangements that permit such contemporaneous payment and delivery of the release; and
(6)    at any time when a Parity Lien Debt Default has occurred and is continuing, the Collateral Trustee will make best 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 4.2    Delivery 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. The Parity Lien Representatives will not be obligated to take notice thereof or to act thereon. 
Section 4.3    Collateral Trustee not Required to Serve, File or Record. Subject to Section 3.2, the Collateral Trustee is not required to serve, file, register or record any instrument releasing or subordinating its Liens on any Collateral; provided that if the Company or any other Grantor shall make a written demand for a termination statement under Section 9-513(c) of the UCC, the Collateral Trustee shall comply with the written request of the Company or any other Grantor to comply with the requirements of such UCC provision; provided, further, that the Collateral Trustee must first confirm with the Parity Lien Representatives that the requirements of such UCC provisions have been satisfied.

ARTICLE 5     
IMMUNITIES OF THE COLLATERAL TRUSTEE
Section 5.1    No 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 5.2    Appointment 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 5.3    Other 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 and the other Parity Lien Security Documents to which it is a party).
Section 5.4    Solicitation of Instructions.
(a)    The Collateral Trustee may at any time solicit written confirmatory instructions, in the form of, including but not limited to, an Act of Parity Lien Debtholders, an Officers’ Certificate, written instructions 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.
(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 pursuant to 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 5.5    Limitation 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 for its own gross negligence or willful misconduct as determined by a non-appealable final order or judgment of a court of competent jurisdiction.
Section 5.6    Documents 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 satisfactory to it.
Section 5.7    Entitled 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 Subsidiary 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.
Section 5.8    Parity 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 5.9    Actions 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 or the Required Parity Lien Debtholders, as applicable, 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 Parity Lien Secured Parties.  The Collateral Trustee shall not be liable for any action it takes or omits to take in good faith in accordance with an Act of Parity Lien Debtholders.
Section 5.10    Security 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 (or any omission to perform or exercise) unless it has been provided with security or indemnity reasonably 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 or omitting to take such action.
Section 5.11    Rights 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 5.12    Limitations on Duty of Collateral Trustee in Respect of Collateral.
(a)    Beyond the exercise of reasonable care in the custody of Collateral in its possession or control, 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 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 accompanied by such continuation statement, document or instrument in proper recordable form. 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 or assignment contained therein, for the validity of the title of any Grantor 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 Subsidiary Guarantor.
Section 5.13    Assumption 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 5.14    No 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 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 5.15    No 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 5.16    Non-Reliance on Collateral Trustee. The Collateral Trustee shall not be required to keep itself informed as to the performance or observance by the Company or a Subsidiary 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 Subsidiary Guarantor that may come into the possession of the Collateral Trustee or any of its Affiliates. 
Section 5.17    Other Relationships with the Company or Subsidiary 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 Subsidiary Guarantor and its Affiliates as though it was not the Collateral Trustee hereunder and without notice to or consent of the Trustee. 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 Subsidiary Guarantor or its Affiliates (including information that may be subject to confidentiality obligations in favor of the Company, such Subsidiary Guarantor or such Affiliate) and acknowledge that (i) such knowledge is not imputed to the Collateral Trustee or the Trustee and (ii) Wilmington Trust, National Association and its Affiliates 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.

(1)    authorized to exercise corporate trust powers; and
(2)    having a combined capital and surplus of at least $250,000,000.

(8)    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 to be secured by the Collateral or preserving, perfecting or establishing the Liens thereon or the rights of the Collateral Trustee therein; or
(B)    providing for the assumption of the Company’s or any Subsidiary Guarantor’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 the Company or such Subsidiary Guarantor to the extent permitted by the terms of the Indenture and the other Parity Lien Documents, as applicable;
will become effective when executed and delivered by the Company or any other applicable Grantor party thereto and the Collateral Trustee;

(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”),

(10)    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.

(8)    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 Subsidiary Guarantor or any holder of Notes or other Parity Lien Obligations; and
(9)    any Mortgage or other Parity Lien Security Document 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, or (ii) to make other changes that do not have an adverse effect on the validity of the Lien created thereby.
(e)    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 the Intercreditor Agreement or any of the Parity Lien Documents.

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 and the information described in clause (2) of the immediately preceding paragraph.
Section 7.3    Further Assurances.

(b)    Upon the reasonable request of the Collateral Trustee or any Parity Lien Representative at any time and from time to time, the Company and each of the Subsidiary Guarantors will promptly execute, acknowledge and deliver such security documents, instruments, certificates, notices and other documents, and take such other actions as shall 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 holders of Parity Lien Obligations; provided that no such security document, instrument or other document shall be materially more burdensome upon the Company and the Subsidiary Guarantors than the Parity Lien Document executed and delivered (or required to be executed and delivered promptly after the date hereof) by the Company and the Subsidiary Guarantors in connection with the issuance of the Notes on or about the date hereof.
(c)    From and after the date hereof, the Company shall, or shall cause the applicable Subsidiary Guarantor to, deliver such documents and takes such actions as are required by Article 12 of the Indenture.

Section 7.4    Successors and Assigns.
(j)    Except as provided in Section 5.2, 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.
