If (a) a portion of the Assets is damaged or destroyed by fire or other casualty prior to Closing (“Casualty Loss”) and such Casualty Loss is not a Major Casualty Loss, or (b) such Casualty Loss is a Major Casualty Loss but neither Seller nor Buyer elect to terminate this Agreement as permitted in this Section 5.2, then (i) this Agreement will remain in full force and effect and the Parties shall proceed to close the Transaction, without adjustment or reduction to the Purchase Price, (ii) the insurance proceeds shall be paid to Seller to be used and applied as provided in the Lease, and (iii) Seller will commence to repair, restore and/or replace the Assets or part thereof damaged or destroyed by such fire or other casualty as soon as reasonably practicable to substantially the same condition as immediately prior to the Casualty Loss and in a manner consistent with the applicable

provisions of the Lease (the “Restoration Operations”), (iv) if the Restoration Operations cannot be completed prior to the Closing Date but can be completed prior to the Outside Closing Date, the Closing Date shall be automatically extended until the Restoration Operations are complete (but not beyond the Outside Closing Date), and (v) if the Major Casualty Notice indicates that the Restoration Operations cannot be completed by the Outside Closing Date and neither Seller or Buyer terminates the Agreement pursuant to this Section 5.2, then the Outside Closing Date shall be automatically extended until the estimated completion date for the Restoration Operations as set forth in the Major Casualty Notice. If Seller determines in good faith that either (A) the Casualty Loss is greater than Ten Million Dollars ($10,000,000), or (B) the casualty cannot be repaired, restored or replaced prior to the Outside Closing Date (each, a “Major Casualty Loss”), Seller shall so notify Buyer in writing (“Major Casualty Notice”), and either Seller or Buyer may elect to terminate this Agreement by giving written notice of termination to the other Party within five (5) Business Days following the date of Seller’s Major Casualty Notice. Upon any such termination, neither Seller nor Buyer shall have any further rights or obligations hereunder except those which expressly survive termination. Seller shall consult with Buyer regarding any Casualty Loss in excess of Two Million ($2,000,000.00) and consider in good faith any input from Buyer as to whether such Casualty Loss is a Major Casualty Loss prior to making any determination in respect thereof.

(a) Buyer and Seller acknowledge that BLM consent to the assignment of a right of way or easement from BLM is customarily not requested or obtained until after the closing of the actual assignment of such right of way or easement. Buyer and Seller shall use commercially reasonable efforts after Closing to obtain the BLM Consent, through submission of the BLM Request for Consent to Assignment to Buyer in the form attached hereto as Exhibit B, with such changes to such form as may be required by changes in applicable law or regulations after the Effective Date. Buyer shall pay any costs or expenses assessed by BLM in connection with such BLM Request for Consent to Assignment to Buyer.

(b) Prior to Closing, Seller shall request of the BLM that the BLM Easement issued under the Federal Land Policy Management Act be converted to a right-of-way under the Mineral Leasing Act of 1920 (or issue a new right-of-way under the Mineral Leasing Act of 1920 covering the same lands for the same purposes). If such conversion (or new issuance) is not completed by September 1, 2013, Seller shall, as expeditiously as possible, either (i) obtain the written approval of the BLM to Lessee’s use of such BLM Easement pursuant to the Lease, or (ii) obtain an amendment to such BLM Easement to allow such use and the sublease thereof. Such September 1, 2013, date may be extended by Buyer if Seller has demonstrated to Buyer’s reasonable satisfaction that the conversion (or new issuance) is imminent. Seller shall, as expeditiously as possible, take all action the BLM deems necessary or appropriate (including making any such filings, providing such information, materials and documentation and obtaining such approvals, consents and other action as is necessary or appropriate) in connection with the transfer of the BLM Easements to Buyer, the lease of the BLM Easements by Lessee pursuant to the Lease, and the use of such BLM Easements by Lessee pursuant thereto. For purposes of this Agreement, the term “Other BLM Matters” means the issues, matters and obligations under this Section 5.3(b).

(c) Except for the BLM Consent and the Other BLM Matters, if prior to Closing Seller or Buyer discovers a consent necessary for the valid assignment of the Assets, or a portion thereof, required by either (a) the contract or agreement granting or creating Seller’s rights in an Asset component (other than a consent to assignment of the Records or any part of the Records, which shall not be considered an Additional Required Consent) or (b) a law applicable to the transfer of an Asset component from Seller to Buyer hereunder (other than the BLM Request for Consent to Assignment to Buyer) (each, and except for the BLM Consent and the Other BLM Matters (which are governed by subsections (a) and (b), above), an “Additional Required Consent”) such Party shall promptly notify the other of the need for such Additional Required Consent, the Seller shall use commercially reasonable efforts to obtain such Additional Required Consent, and Buyer shall cooperate (without any obligation on Buyer’s part to make any payments or incur any liabilities) with Seller in a commercially reasonable manner. In connection with Seller’s efforts to acquire any Additional Required Consent, “commercially reasonable efforts” may include the payment of reasonable costs and expenses in connection therewith. Unless and until any such Additional Required Consent is obtained, to the extent permitted by applicable law, the Parties will cooperate in good faith to establish an arrangement reasonably satisfactory to Buyer and Seller under which Buyer would obtain the claims, rights and benefits associated with the Assets (or portion thereof) affected by such Additional Required Consents (the “Non-Assignable Assets”) and under which Seller would enforce for the benefit of Buyer any and all claims, rights and benefits of Seller associated with the Non-Assignable Assets against a third party thereto. Nothing in this Section 5.3 shall be deemed to constitute an agreement by Buyer to exclude from the Assets any of the Non-Assignable Assets. Seller will convey such Non-Assignable Assets to Buyer promptly upon receipt of the requisite Additional Required Consents with the Closing Date for such Non-Assignable Assets being adjusted appropriately, but subject in all other respects to the terms and conditions of this Agreement. Buyer and Seller agree, upon the request and at the expense of Buyer, to use commercially reasonable efforts to acquire consent to the assignment of any of the Records for which consent to assignment is required.

5.4 Nerd Farm Mortgage and Nerd Farm Judgment. For each of the Nerd Farm Mortgage and the Nerd Farm Judgment, Seller shall use commercially reasonable efforts to obtain prior to Closing either (a) a subordination to the Nerd Farm Easement, (b) a release, or (c) agreement of the Title Company to issue to Buyer the Nerd Farm Title Policy without exception for the Nerd Farm Mortgage and Nerd Farm Judgment. Upon receipt of any release or subordination, Seller shall cause such releases and subordinations to be recorded in the applicable public records of Sublette County, Wyoming.

6.1 No Disclosure or Use of Confidential Information. Except as permitted in this Agreement, each Party agrees not to disclose the Confidential Information to any other Person not having a need to know such Confidential Information in connection with the evaluation of the Transaction, and to use all reasonable efforts to protect the confidentiality of such Confidential Information. Notwithstanding the foregoing, each Party may disclose Confidential Information to its Representatives; provided that each Party shall obtain an agreement from such Representatives to abide by the Confidentiality Provisions.

(a) If the Recipient Party is requested, through legal or administrative process, to disclose any Confidential Information, the Recipient Party must (a) disclose only that portion of the Confidential Information that the Recipient Party’s legal counsel advises is required to be disclosed, (b) use its reasonable efforts to ensure that the Confidential Information is treated confidentially, (c) notify the Disclosing Party as promptly as possible of the request for disclosure and the items of Confidential Information to be disclosed; and (d) if requested by Disclosing Party, reasonably cooperate with the Disclosing Party, at the Disclosing Party’s expense, in the Disclosing Party’s efforts to limit disclosure of such Confidential Information.

(b) The Parties acknowledge: (i) that Tortoise Capital Resources Corporation changed its name to CorEnergy and CorEnergy will conduct a public offering of its common stock to partially finance the Transaction and (ii) that the public offering will require or make appropriate the public disclosure of certain Confidential Information. In addition, the Parties acknowledge that CorEnergy is subject to the reporting obligations of the Securities Exchange Act of 1934 (the “34 Act”) and, as a result, it will be required or appropriate that CorEnergy make public disclosure of certain Confidential Information on a periodic basis. Further, the Parties acknowledge that the partners of Buyer will be entitled, under state partnership law and Buyer’s partnership agreement, to access to certain Confidential Information. Notwithstanding the foregoing, the Parties agree that neither Buyer nor CorEnergy shall, under any circumstance contemplated in this subparagraph (b), disclose any Proprietary Information in any securities law filing or to any Person who is a Disqualified Person as that term is defined in the Lease.

6.3 Ownership and Return. All Confidential Information will remain the property of the Disclosing Party, and no right or license is granted to the Recipient Party with respect to any Confidential Information. Except as explicitly noted in Section 13.3(f), nothing in this Agreement creates an agency or partnership relationship between the Parties. Upon the request of the Disclosing Party, the Recipient Party agrees to (a) immediately return to the Disclosing Party or destroy all Confidential Information, including copies of the same, and (b) destroy any memoranda, summaries, reports, documents or analyses created by the Recipient Party that contain or are based in any way on the Confidential Information. Upon the Disclosing Party’s request, the fact of any such destruction must be certified in writing to the Disclosing Party by an officer of the Recipient Party. Notwithstanding the foregoing, in the event the Recipient Party is required by federal securities laws to retain certain records, nothing herein shall prevent the Recipient Party from complying with its ordinary records retention policy, and each Recipient Party may retain Confidential Information contained or reflected in materials presented to its board of directors, to the extent required by law, or which would be unreasonably burdensome for it to destroy (such as archived computer records).

6.4 Standstill. The Recipient Party agrees that while it is in possession of material nonpublic information concerning the Disclosing Party, it will not purchase, sell or otherwise engage in any transaction in or related to the securities of: (a) the Disclosing Party, or (b) any entity in which the Disclosing Party has invested or advises and that is the subject of any of the Confidential Information. Each Party confirms that it is familiar with federal and state securities laws concerning material non-public information. Each Party hereby confirms that it will not use the Confidential Information in any manner inconsistent with those laws.

6.5 Attorneys’ Fees. Notwithstanding anything set forth in this Agreement to the contrary, if the Disclosing Party commences a lawsuit or other proceeding against the Recipient Party under this Article VI and successfully enforces any of the provisions of this Article VI or on account of any damages sustained by the Disclosing Party by reason of the Recipient Party’s proven violation of any provisions of this Article VI, the Recipient Party agrees that it will pay, in addition to other costs and damages, the Disclosing Party’s reasonable attorneys’ fees.

6.6 Announcements. Seller and Buyer shall consult with each other with regard to, and shall jointly review prior to issuance, all press releases and other announcements issued on or after the Effective Date concerning this Agreement or the transactions contemplated hereby so as to ensure consistency of description of the Transaction.

6.7 Injunctive Relief. Notwithstanding anything set forth in this Agreement to the contrary, the Recipient Party agrees that if it breaches any provision of this Article VI, the Disclosing Party may suffer irreparable damages and its remedy at law may be inadequate. Therefore, if the Recipient Party breaches this Agreement, the Disclosing Party will be entitled, in addition to the damages provided for in Section 6.5, above, and all other remedies available to it at law or in equity, to seek equitable relief, including specific performance and injunctive relief to enforce any provision hereof and to restrain the Recipient Party from using or disclosing, in whole or in part, directly or indirectly, any Confidential Information.

6.8 Survival. The Parties shall comply with this Article VI until Closing. The actions of the Parties with respect to Confidential Information after Closing shall be governed by the provisions of the Lease. Notwithstanding the foregoing, the rights of the Parties to enforce the provisions of this Article VI for actions taken prior to Closing shall survive Closing. If, for any reason, this Agreement is terminated and Closing does not occur, the provisions of this Article VI shall survive termination of this Agreement for a period of twelve (12) months following the date of such termination.

7.20 Disclaimers. THE EXPRESS REPRESENTATIONS AND WARRANTIES OF SELLER CONTAINED IN THIS AGREEMENT (COLLECTIVELY “Seller’s Warranties”) ARE EXCLUSIVE AND ARE IN LIEU OF ALL OTHER REPRESENTATIONS AND WARRANTIES, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE. SELLER EXPRESSLY DISCLAIMS ANY AND ALL SUCH OTHER REPRESENTATIONS AND WARRANTIES. WITHOUT LIMITATION OF THE FOREGOING AND, EXCEPT FOR SELLER’S WARRANTIES, THE INTEREST IN THE ASSETS TO BE CONVEYED TO BUYER SHALL BE CONVEYED PURSUANT HERETO WITHOUT (i) ANY WARRANTY, COVENANT OR REPRESENTATION WHETHER EXPRESS, IMPLIED, STATUTORY OR OTHERWISE RELATING TO TITLE TO THE ASSETS (OTHER THAN BY, THROUGH OR UNDER SELLER), THE CONDITION, QUANTITY, QUALITY, EXISTENCE OF DEFECTS, FITNESS FOR A PARTICULAR PURPOSE, CONFORMITY TO THE MODELS OR SAMPLES OF MATERIALS OR MERCHANTABILITY OF ANY EQUIPMENT OR PROPERTY OR ITS FITNESS FOR ANY PURPOSE OR (ii) ANY OTHER EXPRESS, IMPLIED, STATUTORY OR OTHER WARRANTY OR REPRESENTATION WHATSOEVER.

Notwithstanding anything to the contrary in this Agreement, if Buyer elects to proceed to Closing notwithstanding Buyer’s knowledge of the existence of a breach by Seller with respect to any Seller Warranty, Buyer shall be deemed to have waived each such breach and any and all rights and remedies in connection therewith. Seller shall have no liability or obligation to Buyer with respect to the breach of any representation or warranty of which Buyer first learns after Closing unless Buyer delivers written notice to Seller of the alleged breach prior to the end of the Survival Period, which notice must include the information described in clauses (i), (ii) and (iii) of Subsection 14.5(a).

8.7 Buyer’s Evaluation. Buyer has made a complete and thorough investigation and examination of the Assets and the Transaction, employing the levels of due diligence as Buyer has elected to perform in its sole and absolute discretion. To the extent Buyer does not currently have available its own employees who are competent to conduct such examinations and inspections, Buyer has retained such consultants, independent contractors and other professional advisors as necessary to enable it to complete its due diligence and investigation of the Assets and the Transaction as Buyer determines is necessary in its sole and absolute discretion. Except for the Seller Warranties, Buyer acknowledges and agrees that Seller has not made any other representations or warranties, express or implied, written or oral, as to the accuracy or completeness of the information supplied by Seller or any other information relating to the Assets or the Transaction furnished or to be furnished to Buyer or its representatives by or on behalf of Seller, including without limitation any estimate of the value of the Assets or reserves or any projections as to future events. Buyer acknowledges and affirms that it has relied on and will rely solely on the terms of this Agreement and upon its own independent analysis, evaluation and investigation of, and judgment with respect to, the business, economic, legal, tax or other consequences of this Transaction including, without limitation, its estimate and appraisal of the extent, condition and value of the Assets. Buyer and its Representatives have been given opportunities to examine the Assets and the books and records relating to the ownership of the Assets.

8.8 Loan Documents and Ownership Documents and Information.

If Seller first learns of the breach prior to Closing, Seller’s remedies shall be governed solely and exclusively by Section 11.2. Notwithstanding anything to the contrary in this Agreement, in the event Seller elects to proceed to Closing notwithstanding Seller’s knowledge of the existence of a breach by Buyer with respect to any Buyer Warranties, Seller shall be deemed to have waived each such breach and any and all rights and remedies in connection therewith. Buyer shall have no liability or obligation to Seller with respect to the breach of any representation or warranty of which Seller first learns after Closing unless Seller delivers written notice to Buyer of the alleged breach prior to the end of the Survival Period, which notice must include the information described in clauses (i), (ii) and (iii) of Subsection 14.5(a).

During the period following the Effective Date and until Closing, upon Seller’s Knowledge thereof, Seller shall promptly notify Buyer of any events or circumstances which would cause any of Seller’s Warranties to be untrue or inaccurate in any material respect.

(i) Not sell, transfer, lease, encumber, or create a Lien on, exchange, or otherwise dispose of any of the Assets (other than the sale of worn-out or obsolete equipment, spare parts, or minor or insignificant Assets) in a manner which would cause Seller’s Warranties under Section 7.14 hereof to be untrue or incorrect;

(iii) not grant in favor of any Person a preferential purchase right to purchase any Assets;

During the Interim Period, upon acquiring knowledge thereof, Buyer shall promptly notify Seller of any events or circumstances which would cause any of Buyer’s Warranties to be untrue or inaccurate in any material respect.

Notwithstanding anything to the contrary in this Agreement, if Buyer elects to proceed to Closing notwithstanding Buyer’s knowledge of the existence of a breach by Seller with respect to any of such covenants and agreements, Buyer shall be deemed to have waived each such breach and any and all rights and remedies in connection therewith. If Seller first learns of the breach prior to Closing, Seller’s remedies shall be governed solely and exclusively by Section 11.1. Notwithstanding anything to the contrary in this Agreement, in the event Seller elects to proceed to Closing notwithstanding Seller’s knowledge of the existence of a breach by Buyer with respect to any such covenant or agreement, Seller shall be deemed to have waived each such breach and any and all rights and remedies in connection therewith.

The Parties will promptly inform one another of any challenge by any Taxing Authority to any allocation made pursuant to this Section 10.4 and agree to consult and keep one another informed with respect to the status of, and any discussion, proposal or submission with respect to, such challenge.

10.5 Like Kind Exchange.

14.5 Procedure. The indemnifications contained in this Article XIV shall be implemented as follows:

(a) Claim Notice. The Party seeking indemnification under the terms of this Agreement (“Indemnified Party”) shall submit a written “Claim Notice” to the other Party (“Indemnifying Party”) which, to be effective, must state: (i) the amount of each payment claimed by an Indemnified Party to be owing, (ii) the basis for such claim, with supporting documentation, and (iii) a list identifying to the extent reasonably possible each separate item of Loss for which payment is so claimed. The amount claimed shall be paid by the Indemnifying Party to the extent required herein within 30 days after receipt of the Claim Notice, or after the amount of such payment has been finally established, whichever last occurs; provided, however, that any objection to the Claim Notice by the Indemnifying Party must be provided to the Indemnified Party within 15 days of receipt of the Claim Notice and any undisputed portion of the Claim paid within 30 days of receipt of the Claim Notice, or the Indemnifying Party waives its right to protest the Claim.

(b) Information. Within 60 days after the Indemnified Party receives notice of a claim or legal action that may result in a Loss for which indemnification may be sought under this Agreement (a “Claim”), the Indemnified Party shall give written notice of such Claim to the Indemnifying Party. If the Indemnifying Party or its counsel so requests, the Indemnified Party shall furnish the Indemnifying Party with copies of all pleadings and other information with respect to such Claim. At the election of the Indemnifying Party made within 60 days after receipt of such notice, the Indemnified Party shall permit the Indemnifying Party to assume control of such Claim (to the extent only that such Claim, legal action or other matter relates to a Loss for which the Indemnifying Party is liable), including the determination of all appropriate actions, the negotiation of settlements on behalf of the Indemnified Party, and the conduct of litigation through attorneys of the Indemnifying Party’s choice. No settlement of a Claim can result in any liability or cost to the Indemnified Party for which it is entitled to be indemnified hereunder without its consent. If the Indemnifying Party elects to assume control, (i) any expense incurred by the Indemnifying Party thereafter for investigation or defense of the matter shall be borne by the Indemnifying Party, and (ii) the Indemnified Party shall give all reasonable information and assistance, other than pecuniary, that the Indemnifying Party shall deem necessary to the proper defense of such Claim, legal action, or other matter. In the absence of such an election to assume control by the Indemnifying Party, the Indemnified Party will use commercially reasonable efforts to defend, at the Indemnifying Party’s expense, any claim, legal action or other matter to which such other Party’s indemnification under this Article XIV applies until the Indemnifying Party assumes such defense, and, if the Indemnifying Party fails to

assume such defense within the time period provided above, settle the same in the Indemnified Party’s reasonable discretion at the Indemnifying Party’s expense. If such a Claim requires immediate action, the Parties agree to cooperate in good faith to take appropriate action so as not to jeopardize defense of such Claim or either Party’s position with respect to such Claim.

14.6 No Insurance; Subrogation. The indemnifications provided in this Agreement shall not be construed as a form of insurance. Buyer and Seller hereby waive for themselves, their successors or assigns including, without limitation, any insurers, any rights to subrogation for Losses for which each of them is respectively liable or against which each respectively indemnifies the other, and, if required by applicable policies, Buyer and Seller shall obtain waiver of such subrogation from their respective insurers.

14.7 Reservation as to Non-Parties. Nothing herein is intended to limit or otherwise waive any recourse Buyer or Seller may have against any Person not a Party to this Agreement for any obligations or liabilities that may be incurred with respect to the Assets.

B. In order to induce Landlord to enter into the Lease, Guarantor agreed to execute and deliver to Landlord this Guaranty. Guarantor acknowledges that Landlord would not have entered into the Lease without the execution and delivery by Guarantor of this Guaranty.

NOW THEREFORE, in consideration of the premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by Guarantor, Guarantor hereby agrees in favor of Landlord (and Landlord’s successors and assigns) as follows:

1. Guarantor irrevocably guarantees the full and prompt collection of the payment obligations, whether now in existence or hereafter arising, of Tenant to Landlord under the Lease, including without limitation all amounts due to the Landlord as rent or otherwise under the Lease (the “Obligations”); provided, that (a) the amount payable by Guarantor hereunder shall not under any circumstances exceed the sum of Eighty Million and No/100 Dollars (US$80,000,000), and (b) this Guaranty is limited and conditional in that it is a guaranty of collection only and Guarantor shall be obligated to make payments hereunder only after (i) the Landlord has reduced its claims with respect to the Obligations against the Tenant to judgment and execution has been returned unsatisfied and has not been paid by any Lessee Guarantor (as such term is defined in the Lease) or (ii) if a bankruptcy proceeding has been commenced with respect to Tenant, the closing of the bankruptcy proceeding after its administration under 11 U.S.C.

2.

Guarantor hereby irrevocably waives any and all suretyship defenses, defenses that could be asserted by Tenant (except payment or performance) and all other defenses that would otherwise be available to Guarantor. All payments by Guarantor pursuant to this Guaranty shall be made without setoff. The Landlord shall not be obligated to file any claim relating to the Obligations in the event that the Tenant becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of the Landlord so to file shall not affect the Guarantor’s obligations under this Guaranty. Guarantor irrevocably waives any defense arising by reason of any disability, bankruptcy, reorganization or similar proceeding involving the Tenant. In the event that any payment in respect of any Obligations is rescinded or must otherwise be returned for any reason whatsoever, Guarantor shall remain liable under this Guaranty in respect of such Obligations as if such payment had not been made.

3. Guarantor agrees that the Landlord may at any time and from time to time, either before or after the maturity thereof, without notice to or further consent of the Guarantor, extend the time of payment of, or performance of, or renew, any of the Obligations, and may also make any agreement with the Tenant or with any other party to or person liable on any of the Obligations, or interested therein, for the extension, renewal, payment, compromise, waiver, discharge or release thereof, in whole or in part, or for any amendment or modification of the terms thereof or of the Lease or any other agreement between the Landlord and the Tenant or any such other party or person, without in any way impairing, releasing or affecting the liabilities of the Guarantor under this Guaranty.

5. This Guaranty shall remain in full force and effect and be binding upon the Guarantor, its successors and assigns until all of the Obligations have been satisfied in full and the Lease shall have been terminated or fully performed. This Guaranty may not be modified, discharged or terminated orally or in any manner other than by an agreement in writing signed by Landlord and Guarantor. This is a continuing Guaranty relating to all Obligations, including any arising during any holdover term or arising under transactions renewing or extending the term of the Lease, changing the terms of any Obligations, or creating new or additional Obligations after prior Obligations have in whole or in part been satisfied, regardless of any lapse of time. If any

of the present or future Obligations are guaranteed by persons, partnerships, corporations or other entities in addition to Guarantor, the death, release or discharge, in whole or in part, or the bankruptcy, liquidation or dissolution of one or more of them shall not discharge or affect the liabilities of Guarantor under this Guaranty. The obligations of Guarantor hereunder shall be additional to, and not in substitution for, any security or other guarantee or indemnity at any time existing in respect of Tenant’s obligations, liabilities and covenants under the Lease.

6. No failure on the part of the Landlord to exercise, and no delay in exercising, any right, remedy or power under this Guaranty shall operate as a waiver thereof, nor shall any single or partial exercise by the Landlord of any right, remedy or power under this Guaranty preclude any other or future exercise of any right, remedy or power under this Guaranty. Each and every right, remedy and power granted to the Landlord under this Guaranty or allowed it by law or by the Lease or any other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Landlord from time to time.

(collectively, “Prudential”) as a “Partner”, “Recipient Party”, “Representative” or otherwise agree to maintain the confidentiality of all Confidential Information (herein defined) provided to Lessor or Prudential pursuant to the LGS Transaction Documents. The confidentiality provisions contained in this Exhibit D are intended to consolidate into a single document the confidentiality provisions applicable to Prudential both before and after the effective date of the LGS Equity Investors’ Agreement (the “Effective Date”). The terms of this Exhibit D (as they relate to Prudential) shall be operative and supersede any and all other confidentiality obligations or undertakings contained in any of the LGS Transaction Documents or related agreements. Terms used but not otherwise defined herein shall have the meanings set forth in the LGS Transaction Documents.

(a) General Confidentiality Provisions. Prudential agrees to maintain the confidentiality of the Confidential Information in accordance with procedures adopted in good faith to protect confidential information of third parties delivered to Prudential, provided that Prudential may deliver or disclose Confidential Information to (i) its directors, officers and employees (to the extent such disclosure reasonably relates to the administration of the investment represented by interests in the Partnership, including the Class B Limited Partnership Interests and to the extent such Person is subject to an obligation of confidentiality), (ii) Prudential’s financial advisors, attorneys and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Exhibit D or who are otherwise subject to a professional obligation of confidentiality, (iii) any other Partner in the Partnership which is not a Disqualified Person, (iv) any institutional investor (other than a Disqualified Person) to which Prudential sells or makes a bona fide offer to sell its interests in the Partnership (in accordance with the terms of the Partnership Agreement); provided that such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of Section 26.10 of the Lease, (v) any Person (other than a Disqualified Person) from which Prudential offers to purchase any interest in the Partnership; provided, such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Exhibit D, (vi) any federal or state regulatory authority having jurisdiction over Prudential, (vii) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information about Prudential’s investment portfolio or (viii) any other Person to which such delivery or disclosure may be necessary (w) to effect compliance with any law, rule, regulation or order applicable to Prudential, (x) in response to any subpoena or other legal process, or (y) if a Lessee Event of Default has occurred and is continuing, to the extent Prudential reasonably determines such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under the Lease or other LGS Transaction Documents; provided that in the case of clauses (i) and (ii) above, Prudential shall be responsible for any disclosure by such person in contravention of the terms of this Exhibit D). Prudential agrees in connection with any transfer of an interest in the Partnership to require the transferee to agree and confirm, in writing, that such purchaser accepts the terms and agrees to be bound by the confidentiality provisions contained in the Partnership Agreement, the Equity Investors’ Agreement and the Lease.

(b) Standstill. Prudential acknowledges and agrees that the Confidential Information may constitute material nonpublic information and confirms that it is familiar with federal and state securities laws concerning material non-public information. Prudential confirms that it will not use the Confidential Information in any manner inconsistent with those laws.

(c) Special Restrictions Regarding Proprietary Information. Notwithstanding anything to the contrary set forth in this Exhibit D or elsewhere in the LGS Transaction Documents, no Proprietary Information may, under any circumstance at any time during the term of the Lease and for a period of two (2) years following its termination, be (i) disclosed to any Person who, at the time of such disclosure, is a Disqualified Person, or (ii) without the written consent of Lessee, be disclosed in any document, agreement or exhibit filed pursuant to the federal securities laws or any rules or regulations promulgated thereunder.

(d) Survival, Specific Performance and Equitable Remedies. The obligations of Prudential under this Exhibit D, and of all Persons to whom Confidential Information or Proprietary Information is disclosed by Prudential, shall survive the expiration and termination of the LGS Equity Investors’ Agreement and the Lease and shall continue for a period of two (2) years after termination of the Lease. Prudential acknowledges and agrees (and all Persons to whom Confidential Information or Proprietary Information is disclosed shall be deemed to acknowledge and agree) that Lessee may suffer irreparable harm in the event of a breach of the provisions of this Exhibit D, or by a disclosure of Confidential Information or Proprietary Information by any other Person to whom Confidential Information or Proprietary Information is disclosed hereunder, in each case for which Lessee has no adequate remedy at law. Therefore, in addition to all other remedies available pursuant to the terms of the LGS Equity Investors’ Agreement or at law, Lessee shall have the right to obtain immediate injunctive or other equitable relief upon a breach of this Exhibit D by Prudential or any other Person to whom Confidential Information or Proprietary Information is disclosed.

Base Rent shall be payable on the first day of each calendar month, in advance, during the Term, with the first payment payable on the Effective Date. If Lessee is obligated to pay Base Rent for less than a full calendar month, Base Rent shall be prorated on a daily basis based upon the actual number of days in the prorated month.

5.2 Account for Payment of Base Rent. All payments of Base Rent shall be made to Account No. , reference “ ”, held at , ABA No. , or such other account as Lessor shall advise Lessee in writing from time-to-time, but at least ten (10) Business Days before the date any payment of Base Rent is due.

5.3 Payment to Party Claiming Rent. If any party other than Lessor demands payment of Base Rent or Additional Rent due hereunder and alleges its right to receive the Base Rent or Additional Rent as a result of a Transfer of Lessor’s interest in this Lease or otherwise, Lessee shall not be obligated to honor the demand unless Lessee receives written instructions to do so from the party to whom Lessee is then paying Base Rent or Additional Rent or shall have otherwise received evidence acceptable to Lessee of the right of the party making the demand. The withholding by Lessee of Base Rent or Additional Rent pending the determination of the rights of the party making the demand shall not be a default by Lessee and no interest at the Default Interest Rate or otherwise shall be due with respect to the delay pending such determination.

5.4 Past Due Rent. If any installment of Base Rent is not paid when due, Lessee shall pay to Lessor, on demand, as Additional Rent, interest on such installment from the date such installment was due to the date such installment is paid at the Default Interest Rate. If any other Additional Rent (except for such payments as Lessee is contesting in good faith or pursuant to a Tax Challenge or a Permitted Lessee Contest) is not paid within ten (10) Business Days following written demand from Lessor to Lessee (the “Due Date for Other Additional Rent”), Lessee shall pay to Lessor, on demand, as Additional Rent, interest on such installment from the applicable Due Date for Other Additional Rent to the date such other Additional Rent is paid at the Default Interest Rate.

6.1 Taxes and Impositions. Subject to the other terms and provisions of this Article VI, Lessee shall, before interest or penalties are due thereon, pay directly to the applicable third party and discharge all Taxes and Impositions accruing with respect to the Leased Property during the Term.

6.2 Payment. In the event that any Taxes or Impositions against any of the Leased Property may be paid in installments, Lessee shall have the option to pay such Taxes or Impositions in installments; and in such event, Lessee shall be liable only for those installments which become due and payable during the Term and which accrue or arise with respect to the Leased Property during the Term. Lessee shall prepare and file all tax reports required by Governmental Authorities which relate to the Taxes which accrue or arise with respect to the Leased Property during the Term. Lessee shall be deemed to have satisfied its obligation to pay Taxes as required hereby by paying such Taxes before the earlier of the date (i) any penalty (other than non-delinquent interest) accrues thereon, or (ii) any Lien is imposed against any Leased Property pursuant to Applicable Legal Requirements as a result of such failure (excluding Liens arising and attaching as a matter of law prior to the date such Taxes are due).

6.3 Exclusions from Taxes and Impositions. Notwithstanding the foregoing and for the avoidance of doubt, in no event will Lessee be required to pay, and the terms “Taxes” and “Impositions” shall exclude any and all of the following (collectively, the “Excluded Matters”):

(a) net income taxes (however denominated), gross receipts, net receipts or gross income taxes (however denominated, that are imposed in lieu of net or gross receipts or income taxes) or franchise taxes of Lessor, any Equity Investor or any Affiliate of Lessor; and

(b) any tax imposed with respect to the sale, exchange or other disposition by Lessor, any Equity Investor or any Affiliate of Lessor, in whole or in part, of the Leased Property, Lessor’s interest in this Lease or any Equity Investor Interest; and

(c) taxes on, or with respect to or measured by the capital or net worth of Lessor, any Equity Investor or any Affiliate of Lessor or in the nature of a franchise, use, or margin tax or a tax for the privilege of doing business; and

(e) excess profits taxes, accumulated earnings taxes, capital gains taxes, succession or estate taxes or personal holding company taxes; and

(f) taxes imposed on or against or with respect to Lessor, any Equity Investor or any Affiliate of Lessor to the extent such taxes would not have been imposed if Lessor, any Equity Investor or any Affiliate of Lessor had not engaged in activities, or had a presence in, the taxing jurisdiction which activities or presence is unrelated to this Lease; and

(g) taxes imposed as a result of any voluntary or Involuntary sale, Transfer or other conveyance by Lessor, any Equity Investor or any Affiliate of Lessor; and

(h) taxes that are interest, penalties or additions to tax (or similar fees or charges) that are imposed as a result of the failure of Lessor, any Equity Investor or any Affiliate of Lessor to file any return or other filing properly and timely unless such failure is caused by Lessee failing to fulfill its obligations under this Lease; and

(i) any tax resulting from or that would not have been imposed but for the existence of Liens attributable to Lessor, any Equity Investor or any Affiliate of Lessor; and

(j) taxes to the extent that the amount of such tax is greater than the amount of taxes that would have been imposed if Lessor were not a successor or assignee of Pinedale Op .Co., LP; and

(k) taxes imposed under the Code or ERISA with respect to any Person other than Lessee and its Affiliates; and

(l) sales, transfer, recording, mortgage and similar taxes which Lessor is required to pay pursuant to the Purchase Agreement; and

(o) any increase in taxes resulting from a Transfer or other conveyance by Lessor or any Equity Investor of all or any portion of the Leased Property or Lessor or any interest therein; and

(q) taxes, fees or amounts due and owing under or in connection with any Lien against the Leased Property, this Lease or any Equity Investor Interest; and

(r) assessments, charges or other matters due and owning under any Other Recorded Documents executed by, through or under Lessor in violation of this Lease.

6.4 Payment of Taxes and Impositions. If bills or invoices in respect of a Tax or an Imposition are received by Lessor, Lessor shall, within ten (10) Business Days of Lessor’s receipt thereof, but in any event at least ten (10) Business Days prior to the due date for the related Tax or Imposition (provided that Lessor has received such bill or invoice prior to ten (10) Business Days preceding such due date), deliver to Lessee any bill or invoice with respect to any Tax or Imposition. All taxing authorities shall be instructed to send all Tax invoices to Lessee. Within thirty (30) days after Lessor or Lessee has received confirmation of payment on account of Taxes, such Party shall provide to the other Party a copy of such confirmation that such Tax was paid.

6.5 Abatements. For the purpose of determining payments due from Lessee under this Article VI, Taxes and Impositions shall be the Taxes and Impositions assessed until such time as the Taxes and Impositions are reduced by abatement, refund or rebate. If any abatement, refund or rebate is granted, the Taxes or Impositions, as applicable, shall be the Taxes or Impositions as so reduced. Any rebate, refund or abatement received subsequent to payment of such Taxes or Impositions by Lessee shall be refunded to Lessee by Lessor within ten (10) Business Days of receipt by Lessor, even if the abatement is received after the expiration or earlier termination of this Lease, and such obligations shall survive termination of this Lease. If Lessor or any taxing authority applies any rebate, refund or abatement as a credit against Taxes or Impositions due for a period following the termination of this Lease, then the rebate, refund or abatement shall be deemed received by Lessor upon granting of the rebate, refund or abatement. If Lessor or any taxing authority fails to refund any rebate, refund or abatement to Lessee within thirty (30) days after receipt (other than any rebate, refund or abatement that will be applied as a credit against Taxes and Impositions due for another period), Lessee shall be entitled to interest calculated at the Default Interest Rate from the date payment was due until the date payment is made. Any rebate, refund or abatement realized by Lessor prior to payment of the Taxes and Impositions by Lessee shall result in the immediate reduction of Taxes and Impositions then due from Lessee to Lessor.

6.6 Right to Contest Taxes. Lessee shall have the right to file and prosecute to completion an application contesting the amount, validity, or application of any Taxes, contesting the assessed value of all or any portion of any Leased Property, or seeking an abatement of any Taxes (any such application, a “Tax Challenge”) either in its own name or in the name of Lessor, at no cost or expense to Lessor other than any de minimus cost or expense and throughout all administrative and judicial proceedings (trial court and all appeals) until there is a final, nonappealable determination. Lessee may discontinue a Tax Challenge at any time. If Lessee files or prosecutes a Tax Challenge, Lessor and its Affiliates shall cooperate and furnish any pertinent information needed for the Tax Challenge, at no cost or expense to Lessor other than any de minimus cost or expense. Lessee shall be entitled to be reimbursed out of the award for the reasonable costs and expenses occurred in connection with a Tax Challenge. Lessor shall not have the right to file a Tax Challenge with respect to any Taxes accruing during the Term unless the taxing authority requires the Tax Challenge to be filed by Lessor and Lessee requests Lessor to do so. Lessor shall immediately provide Lessee with a copy of any notices or demands from any Governmental Authority or other Persons which concerns Taxes. Upon request of Lessor at any time or from time-to-time, Lessee shall provide a written report to Lessor regarding the status of any such Tax Challenge.

In no event shall the manner in which Lessee pursues any Tax Challenge exacerbate in any material respect the risk to Lessor of civil or criminal liability, penalty or sanction, in addition to such risks as may

exist for the matters that are the subject of the Tax Challenge prior to such Tax Challenge, and except for liabilities, penalties or sanctions for which Lessee may, and in fact does, post a bond. Further, the manner in which Lessee pursues a Tax Challenge shall not exacerbate in any material respect the risk to Lessor of defeasance of its interest in the Leased Property in addition to the risk of such defeasance as may exist for the matters that are the subject of the Tax Challenge prior to such Tax Challenge and except for such risk which Lessee may, and in fact does, bond around. Lessee agrees that Lessee shall use commercially reasonable efforts to diligently prosecute any such Tax Challenge to a final conclusion, except that Lessee shall have the right to attempt to settle or compromise such contest through negotiations and to discontinue any such Tax Challenge at any time. Lessee shall promptly after the final determination of such Tax Challenge, fully pay and discharge the amounts which shall be levied, assessed, charged or imposed or be determined to be payable therein or in connection therewith, together with all penalties, fines, interest, costs and expenses thereof or in connection therewith, and perform all acts the performance of which shall be ordered or decreed as a result thereof.

6.7 Right to Contest Impositions. Lessee shall have the right to contest Impositions pursuant to Permitted Lessee Contests.

7.1 Lessee Maintenance of Leased Property. During the Term, Lessee shall (a) maintain the Leased Property in Good Condition and Repair, subject to reasonable and ordinary wear and tear, and subject to the provisions of Articles X, XV and XVI, and (b) pay all maintenance and operating costs of the Leased Property in the ordinary course of business. Lessee waives any right to (i) require Lessor to maintain, repair, replace or rebuild all or any part of the Leased Property or (ii) make repairs at the expense of Lessor pursuant to any Applicable Legal Requirements at any time in effect. Subject to Permitted Lessee Contests and the other provisions of this Lease, Lessee, at its own expense, will make (or cause to be made) such alterations and modifications in and additions to the Improvements and Personal Property as may be required from time-to-time to satisfy Applicable Legal Requirements in all material respects in a manner consistent with Article X. Nothing in this Section 7.1 or otherwise in this Lease imposes any obligations upon Lessee, or waives any of Lessee’s rights, with respect to Lessor’s Environmental Liabilities.

7.2 No Trespass. Lessor authorizes Lessee to enforce any no trespass actions regarding any Real Property and to initiate any proceedings to remove any third parties from the Land (to the extent allowable under the applicable Easements) which Lessee, in Lessee’s reasonable business judgment, deems necessary or appropriate for Lessee’s continued quiet enjoyment of the Leased Property. Lessee shall endeavor to give Lessor notice when exercising rights under this Section 7.2.

8.1 Payment of Utility Charges. Lessee shall contract for, in its own name, and pay when due, all charges for the connection and use of water, gas, electricity, and other utility services, if any, supplied to the Leased Property during the Term. Under no circumstances shall Lessor be responsible for any interruption of any such utility service unless caused by the negligence, gross negligence or willful acts or omissions of any Lessor Party. If utilities serving the Leased Property are so disrupted on account of the negligence, gross negligence, or willful act or omission of any such Lessor Party, Lessor shall promptly restore the utilities at Lessor’s sole cost and expense.

9.1 Lessee Use. The Leased Property may be used for any use permitted by Applicable Legal Requirements and the terms and conditions of the Easements and other Record Agreements. During such time as this Lease is in effect, Lessee shall, at Lessee’s sole cost and expense and subject to Permitted Lessee Contests, comply in all material respects with all Applicable Legal Requirements now or hereafter in force relating to or affecting the Leased Property and Lessee’s use, occupancy, operation, maintenance, alteration and/or improvement thereof. Notwithstanding the preceding or any other provision of this Lease to the contrary, (a) Lessor shall be fully responsible for any violation of Applicable Legal Requirements caused at any time by (i) any Lessor Party or (ii) any Lessor Lender; or (iii) any of their respective officers, agents, contractors, servants or employees, except to the extent such violation is caused by the failure of Lessee to perform its obligations hereunder, and (b) Lessee shall have no responsibility for any such matter described in subsection (a). Lessee shall have the right to delay making the changes, alterations and/or additions Lessee is responsible for making pursuant to the immediately preceding provisions of this Section 9.1 while Lessee is contesting in good faith the action or actions being taken by a Governmental Authority pursuant to a Permitted Lessee Contest.

9.2 Operating Requirement. In no event shall Lessee be obligated to keep all or any part of any Leased Property operating. If Lessee discontinues operations, Lessee shall comply in all material respects with all Applicable Legal Requirements and otherwise comply in all material respects with the terms and conditions of this Lease except as to the continuing operation of the Leased Property. Subject to the other terms and conditions of this Lease regarding Lessee’s right in certain circumstances to terminate this Lease and / or to offset Base Rent and Additional Rent against amounts due from Lessor hereunder, Lessee shall pay the Base Rent as and when due under this Lease during any period in which Lessee discontinues operations in whole or in part.

(a) Permitted Capital Improvements and Additional Lines. Notwithstanding anything set forth in this Lease, Lessee, at its own expense and without Lessor’s approval, shall have the right, at any time and from time-to-time as Lessee deems necessary or desirable, to make Permitted Capital Improvements and Additional Lines.

(b) Non-Removable Additions. If Lessee proposes to construct Permitted Capital Improvements and Additional Lines that are not readily removable or cannot be detached from the Liquids Gathering System without adversely affecting the structural integrity or functionality of the Liquids Gathering System (each, a “Non-Removable Addition”), Lessee may provide Lessor written notice (a “Notice of Non-Removable Addition”), which Notice of Non-Removable Addition shall (i) describe the Non-Removable Addition in reasonable detail, (ii) provide a good faith estimate of the total cost of constructing the Non-Removable Addition, (iii) offer Lessor the option to both (A) pay for such Non-Removable Addition, and (B) engage the services of Lessee as construction agent for Lessor with respect to the construction of such Non-Removable Addition, and (iv) specify an increase in the Base Rate if Lessor elects to pay for and engage Lessee as Lessor’s construction agent for such Non-Removable Addition. Lessor shall not have the option to pay for such Non-Removable Addition unless Lessor also engages the services of Lessee as construction agent for such Non-Removable Addition. Lessor shall, by written notice delivered to Lessee within ten (10) Business Days after receipt of the Notice of Non-Removable Addition, elect in writing either to pay for and engage Lessee as Lessor’s construction agent for such Non-Removable Addition or to refrain from paying

for such Non-Removable Addition; failure to give such timely notice shall constitute Lessor’s election not to pay for such Non-Removable Addition; provided, however, that Lessor shall consider such offer as set forth in such Notice of Non-Removable Addition in good faith and use commercially reasonable efforts to obtain financing for such Non-Removable Addition. If Lessor accepts such offer, Lessor shall pay for such Non-Removable Addition and engage Lessee as Lessor’s construction agent for such Non-Removable Addition. In the event Lessor elects to pay for such Non-Removable Addition and engage Lessee as Lessor’s construction agent, such Non-Removable Addition shall become a part of the Leased Property under this Lease, with an increase in Base Rent as indicated in the Notice of Non-Removable Addition, unless Lessor and Lessee instead agree that such Non-Removable Addition shall be the subject of a separate lease, upon substantially the same terms as this Lease, but with Base Rent as set forth in the Notice of Non-Removable Addition. In the event Lessor timely elects to pay for such Non-Removable Addition and engage Lessee as Lessor’s construction agent for such Non-Removable Addition on the terms in the Notice of Non-Removable Addition, (I) Lessor and Lessee shall execute the necessary documents to evidence such amendment to this Lease or a new lease for such Non-Removable Addition, as applicable, (II) Lessor and Lessee shall execute documents, reasonably satisfactory to each of them, governing advances by Lessor to pay costs of such Non-Removable Addition, (III) upon completion of such Non-Removable Addition, Base Rent under this Lease shall be increased or shall be payable under the new lease at the rate provided in the Notice of Non-Removable Addition, and (IV) Lessor shall be the owner of, and Lessee shall be the lessee of, such Non-Removable Addition. If Lessor elects not to pay for such Non-Removable Addition and Lessee elects to proceed with construction of the Non-Removable Addition, then subject to subsection (e), below, such Non-Removable Addition shall remain the sole property of Lessee, and this Lease shall continue in full force and effect.

(c) Removable Additions. If Lessee proposes to construct Permitted Capital Improvements and Additional Lines that are not Non-Removable Additions (each, a “Removable Addition”), Lessee may provide Lessor written notice (a “Notice of Removable Addition”), which Notice of Removable Addition shall (i) describe the Removable Addition in reasonable detail, (ii) provide a good faith estimate of the total cost of constructing the Removable Addition,(iii) offer Lessor the option to both (A) pay for such Removable Addition, and (B) engage the services of Lessee as construction agent for Lessor with respect to the construction of such Removable Addition, and (iv) specify an increase in the Base Rate if Lessor elects to pay for and engage Lessee as Lessor’s construction agent for such Removable Addition. Lessor shall not have the option to pay for such Removable Addition unless Lessor also engages the services of Lessee as construction agent for such Removable Addition. Lessor shall, by written notice delivered to Lessee within ten (10) Business Days after receipt of the Notice of Removable Addition, elect in writing either to pay for and engage Lessee as Lessor’s construction agent for such Removable Addition or to refrain from paying for such Removable Addition; failure to give such timely notice shall constitute Lessor’s election not to pay for such Removable Addition; provided, however, that Lessor shall consider such offer as set forth in such Notice of Removable Addition in good faith and use commercially reasonable efforts to obtain financing for such Removable Addition. If Lessor accepts such offer, Lessor shall pay for such Removable Addition and engage Lessee as Lessor’s construction agent for construction of such Removable Addition. In the event Lessor elects to pay for such Removable Addition and engage Lessee as Lessor’s construction agent, such Removable Addition shall become a part of the Leased Property under this Lease, with an increase in Base Rent as indicated in the Notice of Removable Addition, unless Lessor and Lessee instead agree that such Removable Addition shall be the subject of a separate lease, upon substantially the same terms as this Lease, but with Base Rent as set forth in the Notice of Removable Addition. In the event Lessor timely elects to pay for such Removable Addition and engage Lessee as Lessor’s construction agent for such Removable Addition on the terms in the Notice of Removable Addition, (I) Lessor and Lessee shall execute the necessary documents to evidence such amendment to this Lease or a new lease for such Removable Addition, as applicable, (II) Lessor and Lessee shall execute documents, reasonably satisfactory to each of them, governing advances by Lessor to pay costs of such Removable Addition, (III) upon completion of such Removable Addition, Base Rent under this Lease shall be increased or shall be payable under the new lease at the rate provided in the Notice of Removable Addition, and (IV) Lessor shall be the owner of, and Lessee

shall be the lessee of, such Removable Addition. If Lessor elects not to pay for such Removable Addition and Lessee elects to proceed with construction of the Removable Addition, then subject to subsection (e), below, such Removable Addition shall remain the sole property of Lessee, and this Lease shall continue in full force and effect.

(d) Third Party Financing for Permitted Capital Improvements and Additional Lines. Lessee shall at all times have the right to finance any Permitted Capital Improvements and Additional Lines with a third party without Lessor’s consent; provided, however, that Lessee will notify Lessor in advance of entering into any such financing secured by a Lien on such Permitted Capital Improvements and Additional Lines (as applicable) and give Lessor an opportunity to make a proposal (non-binding on Lessee) to pay for, and engage Lessee as Lessor’s construction agent for, such Permitted Capital Improvements and Additional Lines (as applicable). If requested by Lessee, Lessor agrees to cooperate in good faith with Lessee in the financing of any such Permitted Capital Improvements and Additional Lines (as applicable) that Lessee deems to be necessary or desirable for the operation of the Leased Property or the Lessee Other Activities.

(e) End of Term Ownership. At the end of the Term, (i) all Non-Removable Additions which Lessor elected not to pay for and make a part of the Leased Property pursuant to subsection (b), above, will become the property of Lessor without compensation or reimbursement to Lessee, and (ii) all Removable Additions which Lessor elected not to pay for and make a part of the Leased Property pursuant to subsection (c), above shall be removed by Lessee or, in the case of Additional Lines, detached by Lessee from the Liquids Gathering System unless otherwise agreed by Lessor in writing, and Lessee shall repair any damage to the Leased Property caused by such removal. The transfer of all Non-Removable Additions which become the property of Lessor at the end of the Lease Term pursuant to subsection (i), (A) shall be made on an AS IS WHERE IS basis, without any express or implied warranties from Lessee other than special warranties of title (except as otherwise expressly agreed between the parties at the time of such transfer), provided, however, that such conveyance shall in any event be made by Lessee to Lessor free and clear of (I) any Liens placed on the Leased Property by, through or under Lessee, and (II) any Other Recorded Documents executed by, through or under Lessee in violation of this Lease, and (B) shall be evidenced by Lessee’s execution of such deeds, bills of sale, or other appropriate documents conveying title to such Non-Removable Additions as Lessor and Lessee may reasonably agree, consistent with subsection (A) of this sentence.

10.2 Replacement of Parts. Lessee may, at its own cost and expense, remove in the ordinary course of maintenance, service, repair, overhaul or testing, or as otherwise required or permitted by this Lease, any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use. Lessee will, at its own cost and expense, replace any such Parts as is necessary to maintain the Leased Property in accordance with the standards for Lessee’s maintenance obligations as set forth in Section 7.1 of this Lease. All replacement Parts shall be in as good operating condition as, and shall have a value (including the residual value), utility and remaining useful life at least equal to the Parts replaced, assuming such replaced Parts were in condition and repair required to be maintained by, and otherwise in compliance with, the terms of this Lease (nothing in this Lease, however, shall be construed to require Lessee to replace any Parts having a useful life adequate to operate the Leased Property through the end of the Term). All Parts at any time removed from any item or portion of the Leased Property shall remain the property of Lessor until such time as such Parts shall be replaced by Parts which have been incorporated or installed in or attached to such item or portion of the Leased Property and which meet the requirements for replacement Parts specified above. Immediately upon any replacement Part becoming incorporated into or installed in or attached to any item or portion of the Leased Property, without further act (except in the case of replacement property temporarily installed on an emergency basis), (a) title to such replacement Part shall thereupon vest in Lessor, (b) such replacement Part shall become subject to this Lease and be deemed part of the Leased Property for all purposes to the same extent as the Parts originally incorporated or installed in or attached to the Leased Property, and (c) title to the removed Part shall thereupon vest in Lessee AS IS WHERE IS, free and clear of all rights of Lessor, and shall no longer

be deemed a part of the Leased Property. Notwithstanding the foregoing, “Parts” means all appliances, parts, instruments, appurtenances, accessories, furnishings, spare parts, and other equipment and property of whatever nature which constitute a portion of the Improvements or Personal Property and any replacements or substitutions therefor made under this Section 10.2. “Parts” shall not in any event include (i) any Lessee Property, (ii) removed Parts as provided in subsection (c), above, or (iii) any Permitted Capital Improvements and Additional Lines, which Permitted Capital Improvements and Additional Lines shall be governed by Section 10.1, above. Title to replacements and substitutions for Parts made under this Section 10.2 shall remain a portion of the Leased Property.

10.3 Lessee Other Activities. Notwithstanding anything set forth in this Lease, Lessee, at its own expense and without Lessor’s approval, shall have the right at any time and from time-to-time to conduct Lessee Other Activities.

11.1 Lessee’s Rights. Except (i) as provided in Section 11.2, below, and (ii) to the extent Lessor is required to engage in such communications by Applicable Legal Requirements which are not the subject of a Permitted Lessee Contest and after consultation with Lessee regarding Lessor’s concern that Lessor’s communication with Governmental Authorities is required by Applicable Legal Requirements, but notwithstanding any other provision of this Lease to the contrary:

(a) Ultra Lessee; Leased Property. For so long as an Ultra Entity Person is the Lessee under this Lease, Lessee shall have the exclusive right and obligation to (I) deal with all Governmental Authorities, including the Bureau of Land Management and the Wyoming Oil and Gas Conservation Commission, and (II) conduct all regulatory proceedings, governing or affecting the Leased Property or the ownership, use or operation thereof.

(b) All Lessees; Lessee Property and Lessee Other Activities. Lessee shall have the exclusive right and obligation to (I) deal with all Governmental Authorities, including the Bureau of Land Management and the Wyoming Oil and Gas Conservation Commission, and (II) conduct all regulatory proceedings, governing or affecting the ownership, use or operation of the Lessee Property or the Lessee Other Activities.

(c) Other Lessees; Leased Property. If an Ultra Entity Person is not the Lessee under this Lease, Lessee shall have the right and obligation, but not the exclusive right and obligation, to (I) deal with all Governmental Authorities, including the Bureau of Land Management and the Wyoming Oil and Gas Conservation Commission, and (II) conduct all regulatory proceedings, governing or affecting the use or operation of the Leased Property.

Consistent with the foregoing subsections (a) through (c) of this Section 11.1, Lessor hereby designates Lessee as Lessor’s agent with respect to, and solely with respect to, the exercise of Lessor’s Easement Rights in and to the BLM Easements, but only during the term of and to the limited extent set forth in this Lease. This designation creates a special agency relationship, and Lessee and Lessor expressly acknowledge that the scope of Lessee’s authority to act as agent for Lessor is expressly limited to the use of the BLM Easements as set forth in this Lease and those certain Bureau of Land Management regulatory matters which are enumerated in subsections (a) through (c) of this Section 11.1. Except for such use and enumerated matters, Lessee has and shall have no other power, authority or right to act as agent for Lessor, and Lessee shall have no implied powers or authority to act as agent for Lessor.

At Lessee’s request, Lessor shall execute all such documents and take all such action as may be necessary to ensure and/or evidence Lessee’s rights under this Section 11.1 unless, in Lessor’s reasonable and good faith judgment, such documents or actions will directly result in payments required to be made by Lessor which

Lessee is unwilling to pay on behalf of Lessor and, upon such determination by Lessor and prior to taking any such action, Lessor shall promptly notify Lessee in writing of such determination by Lessor, and Lessor and Lessee shall work diligently and in good faith to resolve their differences with respect to the requested action or document(s). Notwithstanding the foregoing, Lessor shall in any event be required to execute such documents and take all such actions as may be required for Lessee to pursue a Tax Challenge or a Permitted Lessee Contest. Notwithstanding the foregoing, the Parties will cooperate to execute such documents as may be required to extend the terms of the BLM Easements if such documents are required to extend the term of the BLM Easements beyond the Lease Term, it being understood, however, that nothing set forth herein shall obligate Lessor or Lessee for the payment of any extension fee or similar charge imposed by BLM as a condition to such extension other than de minimus costs and expenses.

For the avoidance of doubt, but subject to the introductory language of this Section 11.1 and the immediately preceding paragraph, (i) Lessor shall not in any event engage in any written or verbal communication with any Governmental Authority, including the Bureau of Land Management and the Wyoming Oil and Gas Conservation Commission, regarding or in any way relating to the ownership, use or operation of the Lessee Property or any Lessee Other Activities, (ii) for so long as an Ultra Entity Person is the Lessee under this Lease, Lessor shall not engage in any written or verbal communication with any Governmental Authority, including the Bureau of Land Management and the Wyoming Oil and Gas Conservation Commission, regarding the ownership, use or operation of the Leased Property, and (iii) for so long as a Person other than an Ultra Entity Person is the Lessee under this Lease, Lessor shall not engage in any written or verbal communication with any Governmental Authority, including the Bureau of Land Management and the Wyoming Oil and Gas Conservation Commission, regarding the use or operation of the Leased Property without Lessee’s prior written consent, which consent may be conditioned, to the extent permitted by Applicable Legal Requirements, upon Lessee’s review and approval of any such written communications (including any written materials delivered to such Governmental Authority) and a representative of Lessee being present (via telephone or in person) for any verbal communications. Lessee shall promptly provide Lessor with a copy of any notices or demands received by Lessee from any Governmental Authority which concerns any Applicable Legal Requirement.

Lessor acknowledges and stipulates that Lessee may suffer irreparable harm in the event of a breach of the provisions of this Section 11.1 by Lessor for which Lessee has no adequate remedy at law. Therefore, in addition to all other remedies available pursuant to the terms of this Lease or at law, Lessee shall have the right to obtain immediate injunctive or other equitable relief upon a breach of this Section 11.1 by Lessor.

11.2 Lessor’s Rights. Notwithstanding the foregoing Section 11.1, but subject in any event to Lessee’s right to pursue Tax Challenges and Permitted Lessee Contests, at such time as an Ultra Entity Person is not the Lessee under this Lease, if Lessor determines, in Lessor’s reasonable judgment, that Lessee has not taken sufficient action to protect the interests of Lessor in regard to any such regulatory matter (including, without limitation, regulatory proceedings) with respect to the Leased Property, upon prior written notice to Lessee, Lessor may take such action as may be necessary in order for Lessor to be and remain in compliance with Applicable Legal Requirements as they relate to Lessor and the Leased Property. Lessor shall promptly provide Lessee with a copy of any notices or demands received by Lessor from any Governmental Authority which concerns any Applicable Legal Requirement.

11.3 No Application to Condemnation. Lessor and Lessee acknowledge and agree that the provisions of this Article XI shall not prohibit Lessor from cooperating in condemnation proceedings as required by Article XVI.

12.1 Lessee’s Obligations. If any mechanic’s, materialmen’s or other Liens against any of the Lessor’s interest in the Leased Property in connection with any materials, labor or equipment furnished or claimed to have been furnished to or for any Lessee Party are filed against Lessor’s interests in the Leased Property on account of action or inaction by any Lessee Party (including by Lessee in its capacity as Lessor’s construction agent for Removable Additions or Non-Removable Additions under Article X, other than any such Liens filed as a result of materials, labor or services for Removable Additions or Non-Removable Additions and for which Lessor has failed to meet its obligation to pay the cost of such materials, labor or services), then Lessee shall promptly cause such Lien to be discharged (whether by payment or bond), or, if Lessee desires to contest the Lien, Lessee may do so as long as the enforcement of the Lien is stayed pursuant to a Permitted Lessee Contest, and (b) if a Lessor Lender with respect to Permitted Indebtedness requires Lessor’s interest in the Leased Property to be free of such mechanic’s or materialmen’s liens, then upon request of Lessor or such Lessor Lender, Lessee shall either discharge the Lien or post a bond sufficient to cover the amount of the Lien and interest, penalties and costs that will be payable to discharge the Lien assuming its validity. Notwithstanding the foregoing, Lessee shall have no obligation whatsoever for or with respect to Liens arising from Lessor’s failure to advance payments for Non-Removable Additions or Removable Additions for which Lessor has engaged Lessee as Lessor’s construction agent as provided in Section 10.1.

12.2 Lessor’s Obligations. Lessor shall not permit any mechanic’s, materialmen’s or other Liens against any Leased Property in connection with any materials, labor or equipment furnished, or claimed to have been furnished, to or for Lessor, and if any such Liens shall be filed against any Leased Property on account of any action or inaction by Lessor (other than any action or inaction alleged against Lessor resulting from the failure of Lessee to perform its obligations hereunder), Lessor shall cause the Lien to be discharged, provided that if Lessor desires to contest any such Lien (whether by payment or bond), it may do so as long as enforcement of the Lien is stayed pursuant to a Permitted Lessor Contest.

13.1 No Lien. Lessee is and shall remain the owner of the Lessee Property, other than Non-Removable Additions at the end of the Lease Term as provided in Section 10.1(e). Lessor shall not have any Lien on any of the Lessee Property for the performance of Lessee’s obligations under this Lease or otherwise. LESSOR WAIVES AND DISCLAIMS ALL STATUTORY AND CONTRACTUAL LIEN RIGHTS IN LESSEE PROPERTY NOW OR HEREAFTER PLACED AT OR WITH THE LEASED PROPERTY. Lessor agrees to execute an agreement with Lessee or Lessee’s lender to evidence such waiver of Lessor’s Lien rights in Lessee Property and, following a default by Lessee under any Lessee mortgage, allow Lessee’s lender access to the Leased Property to seize and remove Lessee Property subject to the terms of such agreement, provided that the form and substance of any such agreement is reasonably satisfactory to Lessor, Lessee and Lessee’s lender (including in such agreement reasonable conditions and time periods within which such Lessee Property may be removed). Lessee shall have the right to remove Lessee Property at any time or times during the Term and for a period of thirty (30) days after the expiration of the Term, without any obligation to pay Lessor holdover rent under Section 26.4.

13.2 Sole Risk of Lessee. All of Lessee Property is at Lessee’s sole risk and if any of the Lessee Property is destroyed or damaged other than as a result of the negligence or willful misconduct of a Lessor

Party, no part of the destruction or damage shall be the responsibility of Lessor. If the damage is caused by the negligence or willful misconduct of a Lessor Party, Lessor shall be responsible for any damage or destruction, subject, however, to the waiver of subrogation provisions of Section 14.4. The term “negligence” as used in this Section 13.2 shall not include negligence imputed as a matter of law to Lessor solely by reason of Lessor’s failure to act in respect of matters which are or were the obligation of Lessee under this Lease or solely as a result of Lessor’s ownership of the Leased Property.

13.3 Lessee’s Ability to Grant Liens on Lessee Property. Nothing contained in this Lease shall be deemed to limit or otherwise restrict Lessee’s ability to grant a Lien on Lessee’s interest in the Leased Property under this Lease or on Lessee Property, in any such case to a lender not Affiliated with Lessee for the purpose of securing indebtedness of Lessee or its Affiliates to such lender. Lessor acknowledges and agrees, following a default by Lessee under any Lessee mortgage, to allow Lessee’s lender access to the Leased Property to seize and remove all or any of the Lessee Property and Lessor agrees to execute an agreement with Lessee’s lender to evidence such right as provided in Section 13.1.

14.1 Insurance Coverage. Subject to Section 14.3 below, from and after the Effective Date, Lessee shall maintain with respect to the Leased Property at all times during the Term, at no cost or expense to Lessor, the following types and amounts of insurance:

(a) Liability Insurance. Commercial general liability insurance against claims for bodily injury, death or property damage occurring on, in or about the Leased Property, which insurance shall (i) be written on an “Occurrence Basis”, and shall provide minimum protection with a combined single limit in the amount of $1,000,000 per occurrence and $2,000,000 annual aggregate; and (ii) include premises and operations liability coverage, products and completed operations liability coverage, and blanket contractual liability coverage. In addition, Lessee shall maintain auto liability insurance in an amount not less than $1,000,000;

(b) Worker’s Compensation and Employer’s Liability Insurance. Worker’s Compensation and Employer’s Liability Insurance in accordance with all applicable federal and state law, which shall cover all Lessee’s personnel, invitees, sublessors, guests, consultants, and similar Persons performing under this Lease, with an Employer’s Liability limit shall of not less than one million Dollars ($1,000,000) or such greater amount as may be required by law; and

(c) Property Insurance. “All Risk” Insurance, equal to the full replacement value (as declared) of the Liquids Gathering System, which shall be payable in case of loss and held, paid or applied as provided in Section 15.1 hereof. The policy shall provide that no act or omission of any Person named as insured shall invalidate the interest of, or be a defense against, any other Person named as insured.

(d) Excess Liability Insurance. Excess Liability Insurance covering liabilities arising out of operations worldwide, with a combined minimum limit of not less than $25,000,000 over and above the primary liability limits of all underlying insurance policies as required in this Section.

(e) Builders Risk Insurance. For any alteration, addition, repair or replacement to the Leased Property by Lessee (but excluding any Removable Additions or Non-Removable Additions for which Lessee is acting as Lessor’s construction agent under Article X) for which the estimated cost exceeds $500,000, completed value builder’s risk insurance upon the entire work for the full insurable value replacement cost coverage.

Lessor and Lessee acknowledge and agree that the coverage required hereunder may be provided through a combination of policies that is different than those described above. In addition, Lessee may, at its election, maintain insurance covering additional casualties and events.

14.2 Insurance Requirements Generally. The insurance required by Section 14.1 shall be written by companies having an A.M. Best Insurance Reports rating of not less than “A-” and a financial size category of at least “VII”, and all such companies shall be authorized to do an insurance business in the State of Wyoming, or as otherwise agreed to by Lessor. All insurance policies required to be maintained pursuant to the terms of this Lease (other than the Worker’s Compensation Insurance), shall be endorsed to name Lessor and its successors and assigns (and, at Lessor’s written request and to the extent reasonably practicable, the Lessor Lender or its Agent, Administrative Agent or Collateral Agent) as additional insureds and to provide that such insurance shall be primary over any insurance that may be maintained by Lessor, and, except during the Lease Term (when all insurance proceeds are delivered and paid to Lessee, as loss payee). Notwithstanding anything to the contrary in this Lease, for so long as (a) an Ultra Entity Person, or (b) an Investment Grade Person is the Lessee under this Lease, then in any such case all insurance policies may have such deductibles and self-insured retention amounts as Lessee deems reasonable. If the Lessee is not as provided in the immediately preceding sentence, all insurance policies may have such deductibles and self-insured retention amounts approved by Lessor, which approval shall not be unreasonably withheld so long as the proposed deductibles and self-insurance retention amounts are in the amounts typically obtained for properties or operations similar to the Leased Property by responsible owners and lessees of such property. All insurance required by this Article may be blanket with other insurance maintained by Lessee or any Affiliate of Lessee and may be effected by any combination of basic and excess or umbrella coverage provided: (i) the total amount of the insurance available shall be at least the protection equivalent of separate policies in the amounts required; and (ii) in all other respects, all of the policies shall comply with the applicable provisions of this Article.

Lessee shall pay as they become due all premiums for the insurance required by this Article XIV, shall renew or replace each policy if required to comply with the insurance requirements of this Lease, and shall deliver to Lessor a certificate or other evidence of the existing policy and any renewal or replacement policy (on an ACORD 27 form, in the case of property insurance, and on an ACORD 25 form, in the case of liability insurance, and, in either case, otherwise reasonably satisfactory to Lessor, to the extent reasonably available) as soon as available, but in any event not later five (5) Business Days after the date the new coverage is effective (it being understood that in no event shall Lessee allow any insurance coverage to lapse if and to the extent such insurance is necessary to comply with the requirements of this Lease). In the event of Lessee’s failure to comply with any of the foregoing requirements of this Article XIV within five (5) Business Days of the giving of written notice by Lessor to Lessee (or such shorter period as may be required to maintain the insurance required by this Article XIV in full force and effect), Lessor shall be entitled to procure such insurance. Any sums expended by Lessor in procuring such insurance shall be Additional Rent and shall be repaid by Lessee upon written demand therefor by Lessor, together with interest thereon from the applicable Due Date for Other Additional Rent at the Default Interest Rate.

14.3 Self-Insurance. During any part of the Term, for so long as an Ultra Entity Person or another Investment Grade Person is the Lessee under this Lease, Lessee may self-insure for some or all insurance obligations contained hereunder. If the foregoing sentence is not applicable, the amount of any self-insurance retention shall be subject to the limitations set forth in Section 14.2 above. If Lessee desires to self-insure pursuant to this Section 14.3, Lessee shall deliver to Lessor prior to self-insuring a notice that it intends to self-insure hereunder and a brief summary of the extent to which it intends to self-insure. Ultra Wyoming, on behalf of itself and Ultra Resources and any successor Lessee who is an Ultra Entity Person, hereby notifies Lessor that it intends (and they intend) to self-insure with respect to fire, casualty and property insurance and builder’s risk insurance with respect to the Leased Property. The beneficiaries of Lessee’s self-insurance shall be afforded no less protection than if such self-insured portion was fully insured by an insurance company of the quality and caliber required hereunder, including the provision of a legal

defense and the payment of claims within the same time period that a third-party insurance carrier would have paid such claims. The waiver of subrogation provisions of Section 14.4 shall be applicable to any self-insured exposure.

14.4 Waiver of Subrogation. Each of Lessor and Lessee hereby releases the other from any and all liability for loss or damage caused by fire or any of the extended coverage casualties or any other casualty which shall be brought about by the fault or negligence of the other party or any persons for whom such other party is responsible, provided that this release shall be in force and effect only with respect to loss or damage occurring during such time as the respective party’s policies of property insurance shall contain a clause to the effect that this release shall not affect such policies or right of the releasing party to recover thereunder, and the release shall apply only to the extent of the releasing party’s insurance coverage, provided that, with respect to Lessee’s release of Lessor hereunder, such release shall also apply with respect to any loss occurring during such time as the Lessee is self-insured in accordance with the terms of Section 14.3. Any insurance policy held by Lessee or Lessor, to the extent that waiver is reasonably and customary for the policy in question, shall include a waiver of subrogation clause so long as the same is obtainable. Nothing herein shall be deemed an obligation on the part of Lessor to maintain any insurance and any insurance maintained by Lessor shall serve as excess coverage.

14.5 No Release from Liability. Except as provided in Section 14.4, nothing in this Article XIV shall be deemed to release either party from liability for damages resulting from the negligence or willful misconduct of such party or from responsibility for repairs necessitated by such negligence or willful misconduct. By requiring insurance as provided herein, neither Lessor nor Lessee represents that coverage and limits will necessarily be adequate to protect Lessee or Lessor, and such coverage and limits shall not be deemed as a limitation of the liability of Lessee or Lessor under any indemnification provisions in this Lease. Failure of Lessor to demand such certificate or other evidence of full compliance with these insurance requirements or failure of Lessor to identify a deficiency from evidence that is provided shall not be construed as a waiver of Lessee’s obligation to maintain such insurance.

(a) General Provisions. If all or any part of the Leased Property is damaged or destroyed by fire or other casualty during the Term, then Lessee shall give prompt notice of such event to Lessor and, except as otherwise provided in this Article, Lessee shall, at Lessee’s cost and expense, promptly thereafter repair, restore or replace the Leased Property, or any such part thereof, to substantially the same condition it was in immediately prior to the casualty (subject to any changes to all or any such part of the Leased Property that Lessee intends to make to the extent permitted under this Lease). Notwithstanding the foregoing or anything to the contrary in this Article XV or otherwise, if this Lease is terminated under this Article XV or Section 25.5 (Burdensome Buyout Event) as a result of such fire or other casualty, (i) Lessee shall not be obligated to repair, restore or replace the Leased Property after such fire or other casualty or to pay for such repairs, restoration or replacement, and (ii) neither Lessor nor any other Lessor Indemnified Party shall have any claim against Lessee with respect to the repair, restoration or replacement of the Leased Property or Losses arising from termination of this Lease or Lessee’s purchase of the Leased Property pursuant to this Section 15.1 or Section 25.5. Unless this Lease is terminated pursuant to this Section 15.1 or Section 25.5 as a result of such fire or other casualty,(A) this Lease shall remain in effect following such fire or other casualty, (B) Lessee shall, at Lessee’s cost and expense, promptly repair, restore or replace the Leased Property, or any part thereof, as a result of such fire or other casualty, to substantially the same condition it was in immediately prior to the casualty (subject to changes permitted herein), (C) the rights and obligations of Lessor and Lessee shall remain in effect without abatement, (D) all Base Rent shall continue unabated, and (E) subject to Section 15.2, below, all Casualty Proceeds recovered on account of any damage or destruction to all or any part of the Leased Property by fire or other casualty shall be paid to Lessee.

(b) Lease Termination Option and Purchase Offer. Notwithstanding the above, if the value, as determined by Lessee in good faith, of the damaged or destroyed portions of the Leased Property (determined as of the Casualty Date as if such damage or destruction had not occurred) is greater than fifty percent (50%) of the Insured Value, then Lessee may, by written notice delivered to Lessor within sixty (60) days after such determination, either (i) propose to continue this Lease in effect, or (ii) propose to terminate this Lease and purchase the Leased Property for the purchase price as specified by Lessee in such notice (any such written notice by Lessee electing under subsection (ii) to terminate this Lease and purchase the Leased Property shall be referred to as a “Lessee Casualty Termination Notice”). Lessee’s failure to deliver its Lessee Casualty Termination Notice within such sixty (60) day period shall constitute Lessee’s election to continue the Lease in effect and to repair, restore or replace the damaged or destroyed Leased Property as provided in Section 15.1(a).

(c) Casualty Response Notice. If Lessee delivers its Lessee Casualty Termination Notice to Lessor, then Lessor shall have a period of no more than fifteen (15) days in which to notify Lessee in writing of Lessor’s acceptance or rejection of the Lessee Casualty Termination Notice (“Casualty Response Notice”). Lessor’s failure to provide its Casualty Response Notice within such fifteen (15) day period shall be deemed a rejection of the Lessee Casualty Termination Notice and the Lease shall continue in effect.

(d) Acceptance of Lessee Casualty Termination Notice and Termination of Lease. If Lessor accepts the Lessee Casualty Termination Notice, (i) Lessee shall purchase the Leased Property from Lessor as provided in Section 15.1(e) on a date no later than sixty (60) days after Lessor’s Casualty Response Notice and this Lease shall terminate on such date (the “Casualty Termination Date”), (ii) except the terms and provisions of this Lease which survive termination, neither Lessor nor Lessee shall have any rights or obligations under this Lease arising from and after the Casualty Termination Date, (iii) no further Base Rent or Additional Rent shall accrue with respect to the period after the Casualty Termination Date, (iv) Lessee shall have no repair, restoration or replacement obligations with respect to the fire or other casualty giving rise to the Lessee Casualty Termination Notice and no obligation to pay for such repair, restoration of replacement, (v) neither Lessor nor any other Lessor Indemnified Party shall have any claim against Lessee with respect to the repair, restoration or replacement of the Leased Property or Losses arising from termination of this Lease or Lessee’s purchase of the Leased Property pursuant to this Section 15.1, (vi) each Lessee Guarantor shall be released of liability and obligations under its Lessee Guaranty, Ultra Resources shall be released of liability and obligations under the Resources Guaranty, and each Lessor Guarantor shall be released of liability and obligations under its Lessor Guaranty with respect to (x) as to Lessee Guarantors and Ultra Resources only, matters for which Lessee is released in subsections (iv) and (v), preceding, and (y) matters arising or accruing from and after the Casualty Termination Date, it being understood and agreed, however, that Lessee Guarantors, Ultra Resources and Lessor Guarantors shall remain liable with respect to matters or claims arising or accruing prior to the Casualty Termination Date except those matters described in subsections (iv) and (v) of this Section 15.1(d), and (vii) all Casualty Proceeds shall be paid to Lessee.

(e) Closing of Purchase Offer. In addition, if Lessor accepts the Lessee Casualty Termination Notice, on the Casualty Termination Date, (i) Lessee shall pay to Lessor the purchase price specified by Lessee in the Lessee Casualty Termination Notice or such other purchase price as Lessor and Lessee may mutually agree, (ii) Lessor shall convey the Leased Property to Lessee or its designee on an AS IS WHERE IS basis, without any express or implied warranties from Lessor other than special warranties of title, provided, however, that such conveyance shall in any event be made by Lessor to Lessee or its designee free and clear of (A) all Permitted Lessor Liens, (B) any other Liens placed on the Leased Property by, through or under Lessor; and (C) any Other Recorded Documents executed by, through or under Lessor in violation of this Lease, and (iii) Lessor will deliver to Lessee or its designee such conveyance documents, each in form and substance reasonably satisfactory to Lessee, as Lessee may reasonably request, to transfer the ownership of the Leased Property to Lessee free and clear of the Liens and other items described in subsections (A)-(C) above.

(f) Continuation of Lease if Lessor Rejects the Lessee Casualty Termination Notice. If Lessor rejects or is deemed to have rejected the Lessee Casualty Termination Notice, such Lessee Casualty Termination Notice with respect to termination of the Lease and Lessee’s offer to purchase the Leased Property shall be deemed to be automatically rescinded and this Lease shall remain in full force and effect in accordance with its terms.

(g) No Waiver. Upon each occurrence of a fire or other casualty for which Lessee has the right under this Section 15.1 to give a Lessee Casualty Termination Notice, Lessee shall be entitled to give its Lessee Casualty Termination Notice with respect to such fire or other casualty, even if Lessee previously elected not to give such notice with respect to the occurrence of a prior fire or other casualty and even if prior Lessee Casualty Termination Notice(s) were rejected or deemed rejected by Lessor hereunder.

15.2 Restoration Conditions. Provided that this Lease has not been terminated pursuant to this Article XV above, then Lessee’s repair, restoration or replacement of the Leased Property shall be subject to the following requirements:

(a) Payment of Casualty Proceeds to Lessee. All Casualty Proceeds shall be paid by the insurer to Lessee.

(b) Repair Costs in Excess of $2,000,000. If the cost of such repairs, restoration or replacement as a result of a casualty exceeds $2,000,000 with respect to such casualty, (A) Lessee shall provide to Lessor and Lessor Lender (or the Agent for such Lessor Lender if requested in writing by Lessor) such reasonable documentation related to such repairs, restoration or replacement as Lessor and Lessor Lender (or the Agent for such Lessor Lender if requested in writing by Lessor) may reasonably request to confirm that such repairs, restoration or replacements have been made in the manner required by this Lease, (B) if such repairs, restoration or replacement have not been completed within ninety (90) days following the date of such casualty, Lessee shall pay to the Lessor Lender (or the Agent for such Lessor Lender if requested in writing by Lessor) the amount by which the total cost of such repairs, restoration or replacement exceeds $2,000,000, reduced by repairs, restoration and replacement costs in excess of $2,000,000 completed and paid as of such date, which amounts shall be held and disbursed by such Lessor Lender to Lessee as such repairs, restoration or replacements progress, and (C) Lessor and Lessor Lender (or the Agent for such Lessor Lender if requested in writing by Lessor) will have the right to inspect the Leased Property during normal business hours and after prior reasonable written notice, with Lessee’s representative present and upon the condition that Lessor and Lessor Lender (or the Agent for such Lessor Lender if requested in writing by Lessor) comply with Lessee’s rules and regulations, including safety, (I) to inspect the damage, and (II) to confirm that such repairs, restoration or replacements are being or have been made in the manner required by this Lease; provided that no such inspection shall interfere with the normal operation of the Leased Property or the business of Lessee or its Affiliates.

16.1 Condemnation Damages and Awards. Except to the extent Lessor may be required to make the same available to Lessee under this Article XVI and as otherwise set forth in this Article XVI, Lessee assigns to Lessor any and all rights it may have to any Taking Proceeds and agrees to execute such instruments as may be requested by Lessor to evidence the assignment of such Taking Proceeds to Lessor. Notwithstanding the foregoing, Lessee may make a separate claim for any damages payable for any of the Lessee Property, any so-called special damages to Lessee for interruption to Lessee’s operations or otherwise, or any damages for relocation (collectively, the “Lessee Condemnation Proceeds”), and none of

such Lessee Condemnation Proceeds shall constitute Taking Proceeds. Unless this Lease is terminated pursuant to this Article XVI or Section 25.5 (Burdensome Buyout Event) in connection with a Taking, this Lease shall remain in effect, and the rights and obligations of Lessor and Lessee shall remain in effect without abatement. Lessor and Lessee shall cooperate in good faith to maximize the Taking Proceeds (but without impairing Lessee’s claim for Lessee Condemnation Proceeds) consistent with the terms of this Lease.

(a) General Taking Provisions. If all or any part of the Leased Property is subject to a Taking during the Term, then Lessee shall give prompt notice of such event to Lessor and except as otherwise provided in this Article, Lessee shall, at Lessee’s cost and expense, promptly thereafter repair, restore or replace the Leased Property, or any such part thereof, to substantially the same condition it was in immediately prior to the Taking (subject to any changes to all or any such part of the Leased Property that Lessee intends to make to the extent permitted under this Lease). Notwithstanding the foregoing or anything to the contrary in this Article XVI or otherwise, if this Lease is terminated under this Article XVI or Section 25.5 (Burdensome Buyout Event) as a result of such Taking, (i) Lessee shall not be obligated to repair, restore or replace the Leased Property after such Taking or to pay for such repairs, restoration or replacement, and (ii) neither Lessor nor any other Lessor Indemnified Party shall have any claim against Lessee with respect to such repair, restoration or replacement of the Property or Losses arising from termination of this Lease or Lessee’s purchase of the Leased Property pursuant to this Section 16.2 or Section 25.5. Unless this Lease is terminated pursuant to this Section 16.2 or Section 25.5 in connection with such Taking, this Lease shall remain in effect following such Taking, the rights and obligations of Lessor and Lessee shall remain in effect without abatement, all Base Rent shall continue unabated, and all Lessee Condemnation Proceeds and, subject to Section 16.3, below, Taking Proceeds recovered on account of such Taking shall be paid to Lessee.

(b) Lease Termination Option and Purchase Offer. Notwithstanding the above, if as a result of the Taking, in Lessee’s good faith judgment, the Leased Property can no longer be profitably operated or is no longer suitable for its intended use, then Lessee may, in lieu of repairing, restoring or replacing the same, by written notice delivered to Lessor within sixty (60) days after such determination, either (i) propose to continue this Lease in effect, or (ii) propose to terminate this Lease and purchase the Leased Property for the purchase price specified by Lessee in such notice (any such written notice by Lessee electing under subsection (ii) to terminate this Lease and purchase the Leased Property shall be referred to as a “Lessee Taking Termination Notice”). Lessee’s failure to deliver its Lessee Taking Termination Notice within such sixty (60) day period shall constitute Lessee’s election to continue the Lease in effect and to restore, repair or replace the damaged or destroyed Leased Property as provided in subsection (i) of this Section 16.2(b).

(c) Taking Response Notice. If Lessee delivers its Lessee Taking Termination Notice to Lessor, then Lessor shall have a period of no more than fifteen (15) days in which to notify Lessee in writing of Lessor’s acceptance or rejection of the Lessee Taking Termination Notice (“Taking Response Notice”). Lessor’s failure to provide its Taking Response Notice within such fifteen (15) day period shall be deemed a rejection of the Lessee Taking Termination Notice and the Lease shall continue in effect.

(d) Acceptance of Lessee Taking Termination Notice and Termination of Lease. If Lessor accepts the Lessee Taking Termination Notice, (i) Lessee shall purchase the Leased Property from Lessor as provided in Section 16.2(e) on a date no later than sixty (60) days after Lessor’s Taking Response Notice and this Lease shall terminate on such date (the “Taking Termination Date”), (ii) except as provided in Sections 25.2, 25.3 and 25.4, and the other terms and provisions of this Lease which survive termination, neither Lessor nor Lessee shall have any rights or obligations under this Lease arising from and after the Taking Termination Date, (iii) no further Base Rent or Additional Rent shall accrue with respect to the period after the Taking Termination Date, (iv) Lessee shall have no repair, restoration or replacement obligations or

payment obligations with respect thereto with respect to such Taking or damages caused thereby, (v) neither Lessor nor any other Lessor Indemnified Party shall have any claim against Lessee with respect to repair, restoration or replacement of the Leased Property or Losses arising from termination of this Lease or Lessee’s purchase of the Leased Property pursuant to this Section 16.2, (vi) each Lessee Guarantor shall be released of liability and obligations under its Lessee Guaranty, Ultra Resources shall be released of liability and obligations under the Resources Guaranty, and each Lessor Guarantor shall be released of liability and obligations under its Lessor Guaranty with respect to (x) as to Lessee Guarantors and Ultra Resources only, matters for which Lessee is released in subsections (iv) and (v) of this Section 16.2(d), preceding, and (y) matters arising or accruing from and after the Taking Termination Date, it being understood and agreed, however, that Lessee Guarantors, Ultra Resources and Lessor Guarantors shall remain liable with respect to matters or claims arising or accruing prior to the Taking Termination Date except those matters described in subsections (iv) and (v), and (vii) all Taking Proceeds shall be paid to Lessee. Following a termination of this Lease under this Section 16.2, Lessee’s right of first refusal under, and the other terms and conditions of, Sections 25.2, 25.3 and 25.4, and the other terms and provisions of this Lease which survive termination, shall remain in full force and effect.

(e) Closing of Purchase Offer. In addition, if Lessor accepts the Lessee Taking Termination Notice, on the Taking Termination Date (i) Lessee shall pay to Lessor the purchase price specified by Lessee in the Lessee Taking Termination Notice or such other purchase price as may be agreed by Lessor and Lessee, (ii) Lessor shall convey the Leased Property to Lessee or its designee on an AS IS WHERE IS basis, without any express or implied warranties from Lessor other than special warranties of title, provided, however, that such conveyance shall in any event be made by Lessor to Lessee or its designee free and clear of (A) all Permitted Lessor Liens, (B) any other Liens placed on the Leased Property by, through or under Lessor; and (C) any Other Recorded Documents executed by, through or under Lessor in violation of this Lease, and (iii) Lessor will deliver to Lessee or its designee such conveyance documents, each in form and substance reasonably satisfactory to Lessee, as Lessee may reasonably request, to transfer the ownership of the Leased Property to Lessee free and clear of the Liens and other items described in subsections (A)-(C) above.

(f) Continuation of Lease if Lessor Rejects the Lessee Taking Termination Notice. If Lessor rejects or is deemed to have rejected the Lessee Taking Termination Notice, such Lessee Taking Termination Notice with respect to termination of the Lease and Lessee’s offer to purchase the Leased Property shall be deemed to be automatically rescinded and this Lease shall remain in full force and effect in accordance with its terms.

(g) No Waiver. Upon each occurrence of a Taking for which Lessee has the right under this Section 16.2 to give a Lessee Taking Termination Notice, Lessee shall be entitled to give its Lessee Taking Termination Notice with respect to such Taking, even if Lessee previously elected not to give such notice with respect to the occurrence of a prior Taking and even if prior Lessee Taking Termination Notice(s) were rejected or deemed rejected by Lessor hereunder.

16.3 Restoration Conditions. Provided that this Lease has not been terminated pursuant to Section 16.2, above, in connection with a Taking, then Lessee shall repair, restore or replace the Leased Property damaged as a result of such Taking, as and to the extent required by Section 16.2 and the Taking Proceeds shall be paid as follows:

(a) Payment of Casualty Proceeds to Lessee. All Takings Proceeds shall be paid to Lessee.

(b) Repair Costs in Excess of $2,000,000. If the cost of repairs, restoration or replacement of the Taking exceeds $2,000,000 with respect to such Taking, (A) Lessee shall provide to Lessor and Lessor Lender (or the Agent for such Lessor Lender if requested in writing by Lessor) such reasonable documentation related to such repairs, restoration or replacement as Lessor and Lessor Lender (or the Agent

This subsection (c) shall not in any event be deemed to give Lessor approval rights as to any proposed Permitted Lessee Transferee where such approval rights are not expressly given in the definition of such term, nor shall this subsection (c) be deemed to expand the scope or basis for any such Lessor approval beyond the scope provided in the definition of the term “Permitted Lessee Transferee”.

(d) Lessor Consent to Lease Assignments and Subleases. Exclusive of and separate from Lessor consent rights with respect to a proposed Permitted Lessee Transferee, which are governed by the definition of the term “Permitted Lessee Transferee” and subsection (c), above, Lessor shall not unreasonably withhold its consent for any Lease Assignment or for any Sublease as provided in Sections 17.1(a)(ii) or 17.1(b)(ii), above, and Lessor’s approval of a Lease Assignment or Sublease to the extent required by Sections 17.1(a)(ii) or 17.1(b)(ii), above shall be based solely on the following: (i) the use contemplated under any such Lease Assignment or Sublease does not breach the provisions of Article IX and would not, in Lessor’s reasonable judgment, impair the structural integrity, functionality or value of the Leased Property in any material respect, and (ii) the proposed sublessee or assignee enters into an agreement in a form reasonably satisfactory to Lessor recognizing that such Lease Assignment or Sublease, and any renewals or extensions thereof, are subordinate and subject to the terms of this Lease.

Notwithstanding anything to the contrary set forth in Article XXIII of this Lease or otherwise, and except where a prior Lessee and its Lessee Guarantor and Ultra Resources have been released from liability under this Lease in accordance with Section 17.4, upon the

occurrence of an event or circumstance which would, with the giving of notice or passage of time, or both, constitute a Lessee Event of Default, Lessor shall not declare a Lessee Event of Default or exercise any rights or remedies on account of such Lessee Event of Default unless and until Lessor gives notice of such default to such prior Lessee(s), their respective Lessee Guarantor(s), and Ultra Resources and the opportunity to cure such default, within the period of time permitted under Section 23.1 of this Lease for curing such event or circumstance, but with such cure period as to such prior Lessee, such prior Lessee Guarantor and Ultra Resources beginning only upon receipt by such prior Lessee(s), its Lessee Guarantor(s) or Ultra Resources, as applicable, of such notice.

Subject to the waiver of subrogation provisions in Section 14.4, and except for Losses for which Lessee is responsible pursuant to Section 21.1, and subject to the provisions in Article XIV and Section 26.3, Lessor, to the fullest extent permissible by Applicable Legal Requirements:

(a) Release of Lessee and Lessee Indemnified Parties. Releases Lessee and each other Lessee Indemnified Party from any Losses from any source arising out of or based upon, in whole or in part, (i) any acts or omissions by any Lessor Party, Lessor Indemnified Party or Lessor Lender in violation of the terms of this Lease, the SNDA or the Equity Investor Agreement, (ii) any acts or omissions of any Lessor Party, Lessor Indemnified Party or Lessor Lender with respect to this Lease, the Leased Property, the SNDA or the Equity Investor Agreement, (iii) any Lessor Event of Default, or (iv) the fraud, negligence or willful misconduct of any Lessor Party, Lessor Indemnified Party or Lessor Lender in connection with the Leased Property or the transactions contemplated by this Lease, or in connection with the Equity Investor Agreement or the SNDA; and

(b) Lessor Indemnification of Lessee and Lessee Indemnified Parties. Agrees to indemnify, hold harmless and defend Lessee and each other Lessee Indemnified Party from and against any and all Losses, from any source arising out of or based upon, in whole or in part, (i) any acts or omissions by any Lessor Party or Lessor Indemnified Party in violation of the terms of this Lease, the SNDA or the Equity Investor Agreement, (ii) any acts or omissions of any Lessor Party or Lessor Indemnified Party with respect to this Lease or the Leased Property, the SNDA or the Equity Investor Agreement, (iii) any Lessor Event of Default, or (iv) the fraud, negligence or willful misconduct of any Lessor Party or Lessor Indemnified Party in connection with the Leased Property or the transactions contemplated by this Lease, or in connection with the Equity Investor Agreement or the SNDA;

Provided, however, that in the case of subsections (a) and (b) above, to the extent and in the proportion such Losses also arise out of or are based upon (A) any breach of this Lease by Lessee, (B) the fraud, negligence or willful misconduct of Lessee or any other Lessee Party with respect to the Leased Property, this Lease, the SNDA or the Equity Investor Agreement, (C) Taxes for which Lessee is responsible pursuant to this Lease, or (D) breach by Lessee of any representations made by it in this Lease, then Lessor’s release and indemnification under this subsection (b) shall not apply.

21.3 Concurrent Negligence. Notwithstanding the provisions of Section 21.1 and Section 21.2, in the event of the concurrent negligence or intentional misconduct of Lessee, any other Lessee Party or any Lessee Indemnified Party on the one hand and the concurrent negligence or intentional misconduct of Lessor, any other Lessor Party or Lessor Indemnified Party, on the other hand, a party’s (the “Indemnifying Party”) obligation to indemnify the other as set forth in this Article XXI shall be limited to the extent of the Indemnifying Party’s negligence and/or intentional misconduct (and that of the Lessee Indemnified Parties (if Lessee is the Indemnifying Party) or the Lessor Indemnified Parties (if Lessor is the Indemnifying Party)), including the Indemnifying Party’s proportionate share of reasonable costs, attorneys’ fees, and expenses incurred in connection with any claim, action, or proceeding brought with respect to such injury or damage.

21.4 Survival. The obligations of Lessee and Lessor under this Article XXI shall survive the expiration or earlier termination of this Lease.

21.5 Claims Procedure. In the case of any Losses asserted by an Indemnified Party under this Article XXI, such Indemnified Party shall give prompt notice thereof to the Indemnifying Party and in any event within no less than 60 days after the Indemnified Party receives notice of such assertion; provided that failure to so notify the Indemnifying Party shall not reduce the Indemnifying Party’s obligations to indemnify any Indemnified Party hereunder except to the extent such failure adversely affects the Indemnifying Party’s rights, or materially compromises such Indemnifying Party’s ability, to defend such Losses or results in additional liability on such Indemnifying Party’s part. The Indemnifying Party shall be entitled, at its expense, acting through counsel selected by it (and reasonably satisfactory to such Indemnified Party), to participate in or to assume and control (if it promptly so elects upon notice of the Losses), the negotiation, litigation and/or settlement of any such Losses. Such Indemnified Party may (but shall not be obligated to) participate at its own expense and with its own counsel in any proceeding conducted by the Indemnifying Party in accordance with the foregoing, in which case the Indemnifying Party shall keep such Indemnified Party and its counsel fully informed of all proceedings and filings. Notwithstanding the foregoing, but subject to Article XI and the right of Lessee to pursue Tax Challenges and Permitted Lessee Contests and the right of Lessor to pursue Permitted Lessor Contests, the Indemnifying Party shall not be entitled to assume and control the defense of any Losses if (a) Lessee is the Indemnifying Party, a Level I Lessee Default has occurred and is continuing, or, if Lessor is the Indemnifying Party, a Level 1 Lessor Default has occurred and is continuing, (b) the proceeding involves possible imposition of any criminal liability or penalty or unindemnified civil penalty on the Indemnified Party, or (c) the proceeding involves the granting of injunctive relief against the Indemnified Party not related to this Lease.

22.1 Environmental Undertakings. Lessee’s operations on the Leased Property from and after the Effective Date shall comply with Environmental Laws in all material respects. Lessor will conduct no operations on the Leased Property. After either party discovers or is informed of the existence of a material violation of Environmental Laws with respect to the Leased Property, or receipt of any notices alleging non-ordinary course of business liabilities under Environmental Laws with respect to the Leased Property, that party shall give prompt notice to the other party of such event.

(a) Lessee’s Obligations for Certain Corrective Actions. Except as otherwise provided in Section 25.5, Lessee shall be responsible for performing Corrective Action required under Environmental Law to the extent arising from Lessee Environmental Liabilities, such Corrective Actions to be performed in material compliance with Environmental Laws. Lessee’s obligations to conduct Corrective Action shall be limited to those activities designed to achieve the least stringent remediation permitted under Environmental Laws for a property in similar use as the property requiring Corrective Action.

(b) Lessor’s Obligations for Certain Corrective Actions. Upon Lessee’s written request to Lessor requesting that Lessor take such Corrective Action, Lessor shall be responsible for performing any Corrective Action required under Environmental Laws to the extent arising from Lessor Environmental Liabilities, such Corrective Actions to be performed in material compliance with Environmental Laws. Lessor’s obligations to conduct Corrective Action shall be limited to those activities designed to achieve the least stringent remediation permitted under Environmental Laws for a property in similar use as the property requiring Corrective Action.

22.3 Lessee Environmental Indemnity. Lessee shall, at no cost to Lessor, protect, defend, indemnify, release and hold harmless each of the Lessor Indemnified Parties and each Lessor Lender for, from and against any and all Losses (including engineers’ fees, environmental consultants’ fees, and costs of investigation (including sampling, testing, and analysis of soil, water, air, building materials and other materials and substances whether solid, liquid or gas)) imposed upon or incurred by or asserted against any Lessor Indemnified Parties, but only to the extent arising out of any one or more of the following:

(b) Lessee breach of its covenants in this Article XXII (including Lessee’s obligation to take Corrective Action under Section 22.2(a)).

Lessee’s indemnification obligation does not cover any Losses to the extent attributable to (i) a breach of this Lease by Lessor or any other Lessor Party, (ii) the fraud, negligence or willful misconduct of Lessor, any other Lessor Party or any Lessor Lender, (iii) Lessor Environmental Liabilities, or (iv) Exclusions from Lessee’s Indemnity Obligations. Lessor’s and Lessor Indemnified Parties’ sole and exclusive remedy, either at law, under statute or in equity, against Lessee for Lessee Environmental Liabilities, violations of Environmental Law by Lessee or any other Lessee Party or Releases of Hazardous Materials by Lessee or any other Lessee Party are the remedies in this Section 22.3 and no other rights or remedies shall be applicable thereto, except that Lessee’s failure to perform the Corrective Actions required by Lessee under Section 22.2(a) shall, if not cured within the notice and cure periods provided in Section 23.1(f), or such earlier date as such Corrective Action must be completed to comply with applicable Environmental Law (but subject to any pending Permitted Lessee Contests with respect to same), entitle Lessor to exercise its self-help remedies under Section 23.2 for so long as such Corrective Action remains incomplete.

22.4 Lessor Environmental Indemnity. Lessor shall, at no cost to Lessee, protect, defend, indemnify, release and hold harmless each of the Lessee Indemnified Parties for, from and against any and all Losses (including engineers’ fees, environmental consultants’ fees, and costs of investigation (including sampling, testing, and analysis of soil, water, air, building materials and other materials and substances whether solid, liquid or gas)) imposed upon or incurred by or asserted against any Lessee Indemnified Party, but only to the extent arising out of any one or more of the following:

Lessor’s indemnification obligation does not cover any Losses to the extent attributable to (i) a breach of this Lease by Lessee or any other Lessee Party, (ii) the fraud, negligence or willful misconduct of Lessee or any other Lessee Party, or (iii) Lessee Environmental Liabilities. Lessee’s and Lessee Indemnified Parties’ sole and exclusive remedy, either at law, under statute or in equity, against Lessor for Lessor’s Environmental Liabilities, violations of Environmental Law by Lessor or any other Lessor Party or Releases of Hazardous Materials by Lessor or any other Lessor Party are the remedies in this Section 22.4, except that Lessor’s failure to perform the Corrective Actions required by Lessor under Section 22.2(b) shall, if not cured within the notice and cure periods provided in Section 23.4(i) or such earlier date as such Corrective Action must be completed to comply with applicable Environmental Law (but subject to any pending Permitted Lessor Contests with respect to same), entitle Lessee to exercise its self-help remedies under Section 23.4 for so long as such Corrective Action remains incomplete.

22.5 Claims Procedure. In the case of any Losses asserted by an Indemnified Party under this Article XXII, such Indemnified Party shall give prompt notice thereof to the Indemnifying Party and in any event within no less than 60 days after the Indemnified Party receives notice of such assertion; provided that failure to so notify the Indemnifying Party shall not reduce the Indemnifying Party’s obligations to indemnify any Indemnified Party hereunder except to the extent such failure adversely affects the Indemnifying Party’s rights, or materially compromises such Indemnifying Party’s ability, to defend such Losses or results in additional liability on such Indemnifying Party’s part. The Indemnifying Party shall be entitled, at its expense, acting through counsel selected by it (and reasonably satisfactory to such Indemnified Party), to participate in or to assume and control (if it promptly so elects upon notice of the Losses), the negotiation, litigation and/or settlement of any such Losses. Such Indemnified Party may (but shall not be obligated to) participate at its own expense and with its own counsel in any proceeding conducted by the Indemnifying Party in accordance with the foregoing, in which case the Indemnifying Party shall keep such Indemnified Party and its counsel fully informed of all proceedings and filings. Notwithstanding the foregoing, but subject to Article XI and Lessee’s right to pursue Tax Challenges and Permitted Lessee Contests and Lessor’s right to pursue Permitted Lessor Contests, the Indemnifying Party shall not be entitled to assume and control the defense of any Losses if (a) Lessee is the Indemnifying Party, a Level I Lessee Default has occurred and is continuing, or, if Lessor is the Indemnifying Party, a Level 1 Lessor Default has occurred and is continuing, (b) the proceeding involves possible imposition of any criminal liability or penalty or unindemnified civil penalty on the Indemnified Party, or (c) the proceeding involves the granting of injunctive relief against the Indemnified Party not related to this Lease.

22.6 Survival. It is expressly understood and agreed that Lessee’s and Lessor’s obligations under this Article XXII shall survive the expiration or earlier termination of this Lease.

23.1 Lessee Events of Default. Each of the following shall be an event of default under this Lease (each, subject to the additional notice and cure provisions of Section 17.3, a “Lessee Event of Default”):

(a) Lessee fails to make any payment of Base Rent when due and such failure continues for five (5) Business Days after Lessee’s receipt of written notice from Lessor of such failure; or

(b) Lessee fails to make any Additional Rent (other than a failure to pay Base Rent and except for such payments as Lessee is contesting in good faith or pursuant to a Tax Challenge or a Permitted Lessee Contest) and such failure continues for fifteen (15) Business Days after Lessee’s receipt of written notice of such failure from Lessor; or

(c) any representation and warranty made by Lessee under this Lease is false at the time made and which, individually or in the aggregate with respect to each other such false representation or warranty, is material; or

(d) Lessee makes or permits a Lease Assignment or a Sublease in violation of Article XVII of this Lease, and with respect to a Lease Assignment or Sublease to or with an Affiliate of Lessee, Lessee fails to unwind or terminate such Lease Assignment or Sublease within sixty (60) days after Lessee’s receipt of written notice from Lessor of such breach; or

(e) Lessee fails to maintain property insurance on the Leased Property in material compliance with this Lease, and such failure continues for fifteen (15) Business Days after Lessee’s receipt of written notice of such failure from Lessor; or

(f) Lessee fails to observe or perform any other covenant of Lessee under this Lease and that failure continues for sixty (60) days after Lessee’s receipt of written notice of that breach from Lessor (or if the cure of that failure reasonably requires more than sixty (60) days to complete, if Lessee fails to commence the cure within such sixty (60) day period and thereafter diligently pursue such cure to completion), but with respect to the foregoing, no such uncured failure shall constitute a Lessee Event of Default unless individually or in the aggregate with each other such uncured failure, such failure is material; or

(g) the filing by or against Lessee or Lessee Guarantor of a petition for relief under any Debtor Relief Laws (unless, in the case of a petition filed against Lessee or Lessee Guarantor, the same is dismissed within ninety (90) days after filing), or the appointment of a trustee or receiver to take possession of all, or substantially all, of Lessee’s or Lessee Guarantor’s assets or of Lessee’s interest in this Lease, where such appointment is not discharged in ninety (90) days after appointment of said trustee or receiver, or the voluntary filing of a petition for the appointment of the same; or

(h) Lessee or Lessee Guarantor (i) fails to make any payment of principal or interest with respect to any Material Debt after giving effect to any applicable cure period or (ii) fails to observe or perform any other agreement contained in any agreement or instrument relating to that Material Debt that is a default (other than a failure to pay specified in subsection (i) of this paragraph) and such default continues after the applicable grace or cure period, if any, specified in such agreement or instrument, if the effect of the failure specified in subsection (i) or (ii) is to accelerate the maturity of that Material Debt; or

(i) a breach or default has occurred and is continuing by Lessee under the SNDA and such breach or default continues for thirty (30) days after Lessee’s receipt of written notice of such breach or default from Lessor.

23.2 Lessor’s Remedies for a Lessee Event of Default. Upon the occurrence and during the continuance of a Lessee Event of Default, with or without notice or demand, except such notice as may be required by statute and cannot be waived by Lessee and such notice as is specifically required by the terms of this Lease (all other notices being hereby waived), Lessor shall be entitled to exercise, at its option, the following remedies, Lessor hereby waiving all other rights and remedies to which Lessor may be entitled at law or in equity:

(a) Lessor’s Remedies for a Level 1 Lessee Default. Following the occurrence and during the continuance of a Level 1 Lessee Default only, Lessor shall have, with respect to each such Level 1 Lessee Default either, but not both, of the rights and remedies specified in subsection (i) and subsection (ii), below.

(i) Option to Terminate the Lease. Upon the occurrence and during the continuance of a Level 1 Lessee Default, Lessor may give Lessee written notice of Lessor’s intention to terminate this Lease as a result of such Level 1 Lessee Default (except for the terms and provisions hereof which survive termination) on a date specified in such notice (which date shall be no sooner than sixty (60) days after the date of the notice), in which case, upon the date therein specified, the Term and the estate hereby granted shall expire and terminate as if such date were the date hereinabove fixed for the expiration of the Term except the terms and provisions hereof which survive the Lease Term. Upon such termination, Lessee shall surrender possession of the Leased Property to Lessor and Lessor may take possession of the same on the termination date without being deemed guilty in any manner of trespass or becoming liable for any loss or damage resulting therefrom, without resort to legal or judicial process, procedure or action. If Lessor so terminates this Lease, Lessor may, as full and complete damages for such Level 1 Lessee Default, bring an action against Lessee for any or all of the following:

(A) Accrued and Unpaid Base Rent. All Base Rent accrued and unpaid to the termination date and not otherwise paid by Lessee; and

(B) Accrued and Unpaid Additional Rent. All Additional Rent accrued and unpaid to the termination date and not otherwise paid by Lessee (including Lessee’s indemnity obligations under Sections 21.2 and 22.3 with respect to matters or circumstances arising prior to the date of Lease termination, whether or not Lessor has asserted such indemnity claims prior to the date of Lease termination), but without duplication for amounts for which Lessor seeks damages under this Lease; and

(C) Failure to Surrender Leased Property. Losses resulting from Lessee’s failure to surrender the Leased Property as required by Section 18.1, but without duplication for amounts for which Lessor seeks damages or indemnification under this Lease; and

(D) Collection Costs. All reasonable out-of-pocket expenses incurred by Lessor in enforcing its remedies under this Section 23.2(a)(i) with respect to such Level 1 Lessee Default, including reasonable attorneys’ fees, court costs, expert witness fees, costs of tests and analyses, travel and accommodation expenses, deposition and trial transcripts, copies and other similar costs and fees, paid or incurred by Lessor as a result of its exercise of remedies under this subsection (a)(i) with respect to such Level 1 Lessee Default, regardless of whether or not legal proceedings are actually commenced, subject to Section 26.9 of this Lease, and

(E) Termination Damages. The amount, if any, by which (1) the unpaid Base Rent (as calculated below) payable under this Lease which would have been earned after termination for the balance of the Term (had this Lease not been terminated and without giving effect to any unexercised extension options), discounted to present value at the Discount Rate exceeds (2) the Fair Market Rent for such period, also discounted to present value at the Discount Rate. For purposes of calculating Base Rent which would have been earned after termination for the balance of the Term under (1) above, the Variable Rent component of Total Rents shall be calculated based on the average Variable Rent payable during the one year period prior to the termination of this Lease.

Notwithstanding the foregoing or anything to the contrary set forth in this Lease, the amount required to be paid by Lessee pursuant to Sections 23.2(a)(i)(A), (B), (C), (D) and (E) shall be limited as follows: The Inception Date Present Value of the amount paid by Lessee pursuant to Sections 23.2(a)(i)(A), (B), (C), (D) and (E) plus the Inception Date Present Value of the Aggregate Minimum Rent shall not in any event exceed $200,250,000. As used herein, (I) “Aggregate Minimum Rent” means the Minimum Rent paid by Lessee during the period beginning on Effective Date and continuing through the date of termination of the Lease Term, (II) “Inception Date Present Value” of an amount means the present value of such amount as of the Effective Date, calculated using the Specified Discount Rate, and (III) “Specified Discount Rate” means eight percent (8%).

In addition, and notwithstanding the foregoing, in the event that as of the Lease termination date specified in Lessor’s notice to Lessee such Level 1 Lessee Default has been cured, such termination notice shall be deemed to have been rescinded, this Lease shall remain in effect and Lessor shall only be entitled to Base Rent and Additional Rent which has accrued under the Lease under subsections (A) and (B), above, and Lessor’s reasonable out-of-pocket expenses under subsection (D) above.

(ii) Option to Exercise Remedies Other Than Lease Termination Upon a Level 1 Lessee Default. In the event that Lessor elects NOT to exercise its remedies under subsection (i) above with respect to a Level 1 Lessee Default, and in lieu of its remedies under subsection (i), above, upon the occurrence and during the continuance of a Level 1 Lessee Default, Lessor may exercise any or all of its rights or remedies under subsection (b), below, with respect to such Level 1 Lessee Default.

(b) Lessor’s Remedies for a Lessee Event of Default Other Than Termination Available for a Level 1 Lessee Default. Except as otherwise provided in Section 23.2(a) above with respect to the

exclusivity of such remedies, following the occurrence and during the continuance of any Lessee Event of Default, but only so long as either (x) such Lessee Event of Default does not constitute a Level 1 Lessee Default, or (y) such Lessee Event of Default does constitute a Level 1 Lessee Default and Lessor has elected not to pursue its termination rights as set forth in subsection (a)(i), above, this Lease shall remain in full force and effect, Lessee shall be entitled to remain in possession of the Leased Property hereunder and shall remain obligated and liable for Lessee’s obligations hereunder, and Lessor may exercise the following remedies, concurrently, successively, or in any combination (except NOT in combination with any of the remedies set forth in subsection (a)(i), above, and excluding any other or additional remedies):

(i) Accrued, Unpaid Base Rent. Lessor may bring an action against Lessee for all Base Rent accrued, unpaid and due and owing to the date of such action and not otherwise paid by Lessee; and

(ii) Accrued, Unpaid Additional Rent. Lessor may bring an action against Lessee for all Additional Rent accrued, unpaid and due and owing to the date of such action and not otherwise paid by Lessee (including Lessee’s indemnity obligations under Sections 21.2 and 22.3), but in any case without duplication for claims made under subsection (iii) of this Section 23.2(b), below; and

(iii) Damages. Lessor may bring an action against Lessee for Lessor’s damages which are proximately caused by such Lessee Event of Default, but without duplication for amounts for which Lessee seeks damages or indemnification under this Lease; and

(iv) Specific Performance. Lessor may bring an action against Lessee for specific performance by Lessee of its unperformed obligations under this Lease, but without duplication for other amounts for which Lessor seeks damage or indemnification under this Lease. All covenants and agreements of Lessee in this Lease shall be deemed special, unique and extraordinary, and any breach of any covenant or agreement by Lessee shall be deemed to cause Lessor irreparable injury not properly compensable by damages in an action at law, such that the rights and remedies of Lessor may be enforced both at law or in equity

(v) Self-Help Remedies. Lessor may perform, on Lessee’s behalf, any unperformed covenant or obligation under this Lease constituting such Lessee Event of Default if such covenant or obligation remains unperformed on the date that is not less than ten (10) Business Days after entry of a final and non-appealable court order confirming such Lessee Event of Default, in which event, Lessee shall reimburse Lessor for all reasonable costs, expenses and disbursements incurred by Lessor in doing so, plus together with interest thereon at the Default Interest Rate from the Due Date for Additional Rent, but in any event without duplication for amounts for which Lessor seeks damages or indemnification under this Lease; provided, however, that any action taken by Lessor in accordance with this Section 23.2(b)(v) shall be made in compliance with Lessee’s rules and regulations with respect to the Leased Property; and

(vi) Costs of Collection. Lessor shall be entitled to recover from Lessee all out-of-pocket costs and expenses, including reasonable attorneys’ fees, court costs, expert witness fees, costs of tests and analyses, travel and accommodation expenses, deposition and trial transcripts, copies and other similar costs and fees, paid or incurred by Lessor in exercising its remedies under this Section 23.2(b) as a result of such Lessee Event of Default, regardless of whether or not legal proceedings are actually commenced, subject to Section 26.9 of this Lease.

(c) No Waiver or Election of Remedies. No delay or omission of Lessor to exercise any right or power accruing upon the occurrence and during the continuance of any Lessee Event of Default shall impair any other or subsequent Lessee Event of Default or impair any rights or remedies consequent thereto unless such Lessee Event of Default is cured. Except with respect to the exclusivity of certain remedies as

provided in Sections 23.2(a) and (b), every power and remedy given by this Section to Lessor may be exercised from time-to-time, and as often as may be deemed expedient, by Lessor, subject at all times to Lessor’s right to change any course of action undertaken by Lessor. Lessor hereby irrevocably waives and releases any and all rights and remedies with respect to any Lessee Event of Default other than as expressly granted in this Section 23.2 provided, however, that this sentence shall not be deemed to prohibit collection by Lessor of Base Rent and Additional Rent which has accrued or arisen during the Term, including indemnification claims which arose during the Term pursuant to Sections 21.1 and 22.3, but without duplication of any amounts for which Lessor seeks damages or indemnification under this Lease

23.3 Lessor Events of Default. Each of the following shall be an event of default under this Lease (each, a “Lessor Event of Default”):

(d) Certain Specified Lessor Defaults.

(e) Lessor Default under the SNDA. Any breach, default or failure of performance by Lessor under the SNDA, and such breach, default or failure of performance remains uncured for thirty (30) days after Lessor’s receipt of written notice of such breach, default or failure of performance; or

Any breach, default or failure of performance under (i) Section 17.5(a)(v), (ii) Section 17.5(a)(vi), or (iii) Sections 27.1(b), (c) or (h), and such breach, default or failure of performance remains uncured for sixty (60) days after Lessor’s receipt of written notice of such breach, default or failure of performance, provided, however, that with respect to any such breach, default or failure of performance, Lessor shall be deemed to have cured such breach, default or failure of performance so long as (A) the Transfer which gave rise to such breach, default or failure of performance is null and void ab initio under Lessor’s Governing Documents, (B) Lessor does not recognize any Lessor Equity Interest Owner who (or whose Beneficial Owner(s)) gave rise to such breach, default or failure of performance, (C) Lessor notifies such Lessor Equity Owner(s) in writing that the Transfer which gave rise to such breach, default or failure of performance is null and void, (D) Lessor does not pay or otherwise permit to be made any distribution or other funds or amounts to (I) the transferee of a Lessor Equity Owner if the Transfer to such transferee gave rise to such breach, default or failure of performance, or (II) to a Lessor Equity Interest Owner if one or more of its Beneficial Owner(s) gave rise to such breach, default or failure of performance, (E) Lessor does not make or permit to be made any allocations or other adjustments to the capital or similar account of a Lessor Equity Interest Owner(s) as a result of Lessor income, revenue, gains or otherwise if one or more of its Beneficial Owners gave rise to such breach, default or failure of performance, and (F) Lessor does not permit or allow a Lessor Equity Interest Owner(s) (if one or more of its Beneficial Owners gave rise

to such breach, default or failure of performance) or its Beneficial Owner(s) to: (I) vote or have any influence or involvement in any governance matter, approval, consent or election with respect to Lessor, the Leased Property, Lessee or this Lease, (II) receive from Lessor or any of Lessor’s beneficial owners any financial or other information with respect to Lessor, Lessee, the Leased Property or this Lease, or (III) inspect the Leased Property or otherwise participate in any rights or benefits of Lessor under this Lease; provided further, that even if the conditions in subsections (A)-(F) above remain satisfied, if any Person receives a final judgment holding that (X) such Transfer giving rise to such breach, default or failure of performance is enforceable and remains in effect, or (Y) any of the actions or conditions in subsections (A)-(F), above must cease or are otherwise unenforceable, then such breach, default or failure of performance shall be deemed not to be cured for purposes of this Lease; or

The filing by or against Lessor of a petition for relief under any Debtor Relief Laws (unless the same is dismissed within ninety (90) days after filing), or the appointment of a trustee or receiver to take possession of all, or substantially all, of Lessor’s assets or of Lessor’s interest in this Lease, where such appointment is not discharged in ninety (90) days after appointment of said trustee or receiver, or the voluntary filing of a petition for the appointment of the same.

Upon the occurrence and during the continuance of a Lessor Event of Default, with or without notice or demand, except such notice as may be required by statute and cannot be waived by Lessor and such notice as is specifically required by the terms of this Lease (all other notices being hereby waived), this Lease shall remain in full force and effect, Lessee shall be entitled to remain in possession of the Leased Property hereunder and shall remain obligated and liable for Lessee’s obligations hereunder (subject to Lessee’s offset rights set forth below), and Lessee shall have and may exercise the following remedies, concurrently, successively, or in any combination, Lessee hereby waiving all other rights and remedies to which Lessee may be entitled at law or in equity:

(i) Amounts Due by Lessor under the Lease. Lessee may collect and bring an action against Lessor for all amounts due, owing and unpaid by Lessor as of the date of such action, including Lessor’s indemnity obligations under this Lease with respect to matters or circumstances arising prior to the date of such action, but in any case without duplication for claims made under subsection (a)(ii) below; and

(ii) Damages. Lessee may bring an action against Lessor for Lessee’s damages which are proximately caused by such Lessor Event of Default, but without duplication for other amounts and indemnities for which Lessor may be obligated under this Lease; and

(iii) Specific Performance. Lessee may bring an action against Lessor for specific performance by Lessor of its unperformed obligations under this Lease, but without duplication for other amounts, damages and indemnities for which Lessor may be obligated under this Lease. All covenants and agreements of Lessor in this Lease shall be deemed special, unique and extraordinary, and any breach of any covenant or agreement by Lessor shall be deemed to cause Lessee irreparable injury not properly compensable by damages in an action at law, such that the rights and remedies of Lessee may be enforced both at law or in equity; and

(iv) Self-Help. Lessee may perform, on Lessor’s behalf, any unperformed covenant or obligation under this Lease constituting such Lessor Event of Default if such covenant or obligation remains unperformed on the date that is not less than ten (10) Business Days after entry of a final and non-appealable court order confirming such Lessor Event of Default, in which event, Lessor shall reimburse Lessee for all reasonable costs, expenses and disbursements incurred by Lessee in doing so, plus together with interest thereon at the Default Interest Rate from the date which is ten (10) Business Days after Lessee makes demand on Lessor for payment of same, but in any event without duplication for amounts for which Lessor seeks damages or indemnification under this Lease; and

(v) Enforcement Costs. Lessee shall be entitled to recover from Lessor all out-of-pocket costs and expenses, including reasonable attorneys’ fees, court costs, expert witness fees, costs of tests and analyses, travel and accommodation expenses, deposition and trial transcripts, copies and other similar costs and fees, paid or incurred by Lessee in exercising its remedies under this Section 23.4(a) as a result of such Lessor Event of Default, regardless of whether or not legal proceedings are actually commenced, subject to Section 26.9 of this Lease; and

(vi) Special Payment for a Level 1A Lessor Default. So long as an Ultra Entity Person is the Lessee under this Lease and no Level 1 Lessee Default has occurred and is continuing, upon the occurrence and during the continuance of one or more Level 1A Lessor Defaults, beginning immediately upon notice from Lessee to Lessor, Lessor shall pay to Lessee an amount equal to $10,000 per day until all Level 1A Lessor Defaults are cured (the “Level 1A Lessor Default Payment Amount”). Lessor may choose to pay the Level 1A Lessor Default Payment Amount due hereunder on a monthly basis, on or before the date five (5) Business Days prior to the end of each calendar month, in the amount of the aggregate unpaid Level 1A Lessor Default Payment Amount due through the end of such calendar month. If on the date five (5) Business Days prior to the end of any calendar month Lessor has not paid to Lessee the aggregate Level 1 A Lessor Default Payment Amount due through the end of such calendar month, then Lessee may offset against the monthly payment of Base Rent for the immediately succeeding calendar month the unpaid Level 1A Lessor Default Payment Amount, but in no event may Lessee offset such unpaid Level 1A Lessor Default Payment Amount against any monthly payment of Base Rent in an amount which, when added to any offsets to such monthly payment of Base Rent under subsection (vii) below, would cause such monthly payment of Base Rent hereunder to be less than the Monthly Debt Service for such payment date. Following the cure of all Level 1A Lessor Defaults hereunder, within ten (10) Business Days following delivery of written notice from Lessor to Lessee of (a) evidence reasonably acceptable to Lessee that all Level 1A Lessor Defaults have been cured, and (b) a correct calculation of the total Level 1A Lessor Default Payment Amounts paid by Lessor to Lessee or offset against Base Rent with respect to such Level 1A Lessor Defaults (collectively, with respect to such Level 1A Lessor Defaults, the “Level 1A Default Payments”), then (x) the Level 1A Lessor Payment Amount that has accrued and remains unpaid shall automatically be extinguished, and (y) Lessee shall pay to Lessor (or as otherwise directed by Lessor under this Lease or by Lessor Lender with respect to payment of

Base Rent) the amount of such Level 1A Lessor Default Payments, less any amounts owing to Lessee under the preceding subsections (i)-(v) as of such date, and without payment by Lessee of interest at the Default Interest Rate thereon. Neither payment by Lessor to Lessee of any Level 1A Lessor Default Payment Amount nor Lessee’s offset of any Level 1A Lessor Default Payment Amount against Base Rent as permitted by this subsection (vi) shall be exclusive of any other remedies available under this Section 23.4(a), and Lessee may pursue its other remedies under this Lease with respect to such Level 1A Lessor Default. Lessor and Lessee agree that Lessor’s damages resulting from a Level 1A Lessor Default would be impractical and extremely difficult, if not impossible, to estimate or to determine, and the Level 1A Lessor Default Payment Amount is a fair and reasonable estimate of those damages which has been agreed to in an effort to cause the amount of such damages to be certain; and

(vii) Right to Offset. So long as no Level 1 Lessee Default has occurred and is continuing, in the event Lessor fails to pay to Lessee any amounts due to Lessee pursuant to subsections (i), (ii), (iii), (iv), or (v), above, within ten (10) Business Days after written demand from Lessee, Lessee may offset such delinquent amounts, including interest thereon at the Default Interest Rate, from Base Rent otherwise due and owing by Lessee, whether previously or thereafter due and owing provided, however, that Lessee shall not offset such amounts against any monthly payment of Base Rent in an amount which, when added to any offsets under subsection (vi), above, with respect to such monthly payment of Base Rent, would cause any payment of monthly Base Rent hereunder to be less than the Monthly Debt Service for such payment date.

(b) Delays and Waivers of Other Remedies. No delay or omission of Lessee to exercise any right or power accruing upon the occurrence and during the continuance of any Lessor Event of Default shall impair any other or subsequent Lessor Event of Default or impair any rights or remedies consequent thereto unless such Lessor Event of Default is cured. Subject to the provisions of subsection (a), above, which provide that such remedies are available without duplication of certain other claims, every power and remedy given by this Section 23.4 to Lessee may be exercised from time-to-time, and as often as may be deemed expedient, by Lessee, subject at all times to Lessee’s right to change any course of action undertaken by Lessee. Lessee hereby irrevocably waives and releases any and all rights and remedies with respect to any Lessor Event of Default other than as expressly granted in this Section 23.4. provided, however, that this sentence shall not be deemed to prohibit collection by Lessee of amounts due and owing from Lessor which payment obligation has accrued or arisen with respect to facts or circumstances during the Term, including indemnification claims which arose during the Term pursuant to Sections 21.2 and 22.4, but without duplication of any such amounts or claims and such remedies.

23.5 Mitigation of Damages. Notwithstanding anything to the contrary contained in this Article XXIII, (a) upon the occurrence of a Lessee Event of Default, Lessor shall be obligated to mitigate its damages hereunder, and (b) upon the occurrence of a Lessor Event of Default, Lessee shall be obligated to mitigate its damages hereunder.

24.1 Notices. Except where otherwise specifically provided in this Lease, all notices, demands, requests or other communications (each, a “Notice”) which either party is required to or may desire to give to the other shall be in writing and shall be given by (a) personal delivery, (b) mailing a copy thereof by certified or registered mail, postage prepaid, return receipt requested, or (c) nationally recognized overnight courier service (such as Federal Express or UPS), all charges prepaid, furnishing a receipt upon delivery, in each case addressed to the party to whom the notice is directed at the Notice Address of such party set forth below. A notice given by Lessee may be given, in addition to the methods set forth in the preceding sentence, via electronic mail, and any Notice sent by Lessee via electronic mail shall be deemed to have been received by the addressee upon Lessee sending the email to the addressee’s designated email address below. The Notice Address of each party is:

The addresses to which notices and demands shall be delivered or sent may be changed from time-to-time by notice served by either party upon the other as provided above.

24.2 Deemed Receipt. Unless otherwise provided in this Lease, and except for deemed receipt of email notices as provided in Section 24.1, notice shall be deemed to have been received by the addressee as follows: (a) if a Notice is delivered in person, or sent by registered or certified mail, or nationally recognized overnight courier, upon receipt by the addressee or delivery to the address of the addressee; and (b) if the addressee rejects or otherwise refuses to accept the Notice, or if the Notice cannot be delivered because of a change in address for which no Notice was given, then upon the rejection, refusal, or inability to deliver the Notice.

24.3 Delivery; Time of Notice. Notwithstanding the foregoing, if any Notice is received after 5:00 p.m. on a Business Day where the addressee is located, or on a day that is not a Business Day where the addressee is located, then the Notice is deemed received at 9:00 a.m. local time on the next business day where the addressee is located.

(a) Renewal Rights. Provided no Level 1 Lessee Default has occurred and remains uncured as of the end of the Current Lease Term End, Lessee shall have the right and option (the “Renewal Option”) to extend the term of the Lease with respect to all (but not less than all) of the Leased Property for successive renewal terms, each for a length of time equal to five (5) years, provided, however, that the maximum aggregate Term shall in no event exceed 99 years. Base Rent during each Renewal Term shall be the Fair Market Rent, determined as set forth below.

(b) Lessee Renewal Notice. Prior to the date that is twenty-one (21) months before the Current Lease Term End (the “Renewal Notice Date”), Lessee may exercise its Renewal Option if Lessee and Lessor agree in writing upon the Fair Market Rent for the applicable Renewal Term (the “Agreed FMV Rent”).

(c) Determination of Agreed Fair Market Rent. Lessor and Lessee shall negotiate in good faith to reach agreement as to the Fair Market Rent and, if requested by Lessee, one or more Responsible Officers of Lessor shall meet with one or more Responsible Officers of Lessee at Lessee’s offices in Houston, Texas or such other location as the parties shall mutually agree to conduct such negotiations in person. The Agreed FMV Rent shall be the Base Rent for the Leased Property for the applicable Renewal Term. If Lessor and Lessee are unable to agree upon the Fair Market Rent on or prior to the Renewal Notice Date, Lessee may notify Lessor in writing of its intent to exercise its Renewal Option subject to an acceptable determination of Fair Market Rent on or prior to the Renewal Notice Date (such notice, a “Fair Market Rent Determination Notice”). If the Lessee does not deliver the Fair Market Rent Determination Notice on or before the Renewal Notice Date, Lessee will be deemed to have decided not to elect to exercise the Renewal Term Option and the Lease will expire on the Current Lease Term End. If Lessee delivers a Fair Market Rent Determination Notice to Lessor, then each of Lessor and Lessee shall submit to the other in writing (the “Designation Notice”), no sooner than fifteen (15) Business Days after Lessee’s delivery of such Fair Market Rent Determination Notice and no later than thirty (30) Business Days after Lessee’s delivery of such Fair Market Determination Notice, (i) its good faith estimate of the Fair Market Rent during the applicable Renewal Term (collectively referred to as the “Estimates”), and (ii) the name of the Independent Appraiser appointed by it to determine which of the two (2) Estimates most closely reflects the Fair Market Rent for the Leased Property during the applicable Renewal Term, and Fair Market Rent shall be determined as follows:

(i) If either Lessor or Lessee fails to appoint an Independent Appraiser within the fifteen (15) Business Day period referred to above, the Independent Appraiser appointed by the other party shall be the sole Independent Appraiser for the purposes hereof and shall determine which of the two (2) Estimates most closely reflects the Fair Market Rent within twenty (20) Business Days after the Designation Notice appointing such Independent Appraiser, and the Estimate so chosen shall be binding on both Lessor and Lessee as the Base Rent for the Leased Property during the applicable Renewal Term.

(ii) If both Lessor and Lessee appoint an Independent Appraiser within the fifteen (15) Business Day period referred to above, Lessor’s and Lessee’s Independent Appraisers shall work together in good faith to agree upon which of the two (2) Estimates most closely reflects the Fair Market Rent for the Leased Property within twenty (20) Business Days after the Designation Notices appointing such Independent Appraisers (or the later of the two Designation Notices). The Estimate chosen by such Independent Appraisers shall be binding on both Lessor and Lessee as the Base Rent for the Leased Property during the applicable Renewal Term.

(iii) If the two (2) Independent Appraisers have not agreed upon which of the two (2) Estimates most closely reflects the Fair Market Rent by midnight on the date which is twenty (20) Business Days after the Designation Notices appointing such Independent Appraisers (or the later of the two Designation Notices), then, within ten (10) Business Days after the expiration of such twenty (20) Business Day period, the two (2) Independent Appraisers shall select a third Independent Appraiser. Once the third Independent Appraiser has been selected, then, as soon thereafter as practicable but in any case within fifteen (15) Business Days, the third Independent Appraiser shall make his or her determination of which of the two (2) Estimates most closely reflects the Fair Market Rent and such Estimate shall be binding on both Lessor and Lessee as the Base Rent for the Leased Property during the applicable Renewal Term. If the two (2) Independent Appraisers are unable to agree upon a third Independent Appraiser within such fifteen (15) Business Day period, the third Independent Appraiser shall be appointed as soon as possible by the American Arbitration Association (or any successor organization, or if no successor organization shall then exist, by a court of competent jurisdiction residing in Harris County, Texas, or such other jurisdiction as Lessor and Lessee mutually agree), subject to the qualification requirements set out herein. In the event of the failure, refusal or inability of any Independent Appraiser to act, a new Independent Appraiser shall be appointed in his stead, which appointment shall be made in the same manner as set forth above for the appointment of such resigning Independent Appraiser.

(iv) Notwithstanding the foregoing procedures of this Section 25.1(c), Lessor and Lessee may terminate the foregoing procedures to determine the Fair Market Rent for the applicable Renewal Term, if at any time during the process, they agree in writing as to what constitutes the Fair Market Rent for the applicable Renewal Term and such determination shall be binding on both Lessor and Lessee as the Base Rent for the Leased Property during the applicable Renewal Term.

(v) The parties shall share equally in the costs of the third Independent Appraiser. The fees of any appraiser, counsel or experts engaged directly by Lessor or Lessee shall be borne by the party retaining the appraiser, counsel or expert.

(d) Lessee Right to Rescind Upon Final Determination of Fair Market Rent. If Fair Market Rent is determined pursuant to subsection (c), above, then on or before the date which is thirty (30) days following the determination of the Fair Market Rent pursuant to subsection (c), above, Lessee shall elect, by written notice to Lessor, whether to (i) rescind Lessee’s election to extend the Lease Term for the applicable Renewal Term, in which case Lessee shall be deemed to have elected not to extend the Lease Term for the applicable Renewal Term (although to the extent that Lessee’s rescission notice is given after the date which would otherwise have been the commencement date of such Renewal Term, the Lease shall be deemed to have been extended for such period and Lessee’s possession during such period shall not constitute a default or “holding over” after the Lease Term), or (ii) renew the Lease for the applicable Renewal Term for the Fair Market Rent as so determined, in which case during such Renewal Term all of the terms and conditions of this Lease will continue in full force and effect, with Base Rent being determined as set forth in subsection (c), above. Any failure of the parties to determine Fair Market Rent within the timeframes set forth in this Section 25.1 shall not invalidate any of Lessee’s rights under this subsection (d) or any other provision of this Section 25.1. If Lessee fails to timely notify Lessor in writing of Lessee’s decision to rescind its extension notice or to renew the Lease as provided in this subsection (d), Lessee will be deemed to have elected to rescind its election to extend the Lease Term for such Renewal Term as provided in subsection (i), above. Upon expiration of the Lease Term due to failure of Lessee to extend the Lease Term for a Renewal Term or actual or deemed rescission by Lessee of its election to so extend for the Renewal Term, (A) Lessor may (but shall not be obligated to) market the Leased Property for sale or lease, subject in each case to Sections 25.3 and 25.4 hereof, and (B) the Lease shall terminate except the provisions hereof which survive termination, including Sections 25.3 and 25.4 hereof.

(e) Payment of Renewal Term Base Rent Prior to Final Determination of Fair Market Rent. In the event the procedures outlined in subsections (c) and (d), above, are not completed and, therefore, the Fair Market Rent for the applicable Renewal Term is not determined as of the Current Lease Term End, then Lessee shall pay Base Rent for the Leased Property during the applicable Renewal Term based on the average of the Estimates provided by Lessor’s Independent Appraiser and Lessee’s Independent Appraiser. If it is thereafter determined that the Fair Market Rent for the applicable Renewal Term is an amount different than the amount paid by Lessee, the Fair Market Rent as so determined shall be effective from the date of commencement of the applicable Renewal Term, and Lessee or Lessor, as the case may be, shall pay to the other party, within twenty (20) Business Days after the determination of such Fair Market Rent for the applicable Renewal Term, the difference between the rent payable based upon the Fair Market Rent for the applicable Renewal Term as determined in accordance with the foregoing from the commencement date of the applicable Renewal Term and the total Base Rent actually paid to the date of such payment. If the amount due by Lessor to Lessee or Lessee to Lessor, as the case may be, under the foregoing sentence is not paid within such twenty (20) Business Day period, such amount shall thereafter bear interest from the Due Date for Additional Rent (with respect to payments by Lessee) or ten (10) Business Days following written demand from Lessee to Lessor (with respect to payments by Lessor) at a rate equal to the Default Interest Rate.

25.2 Lessee as Operator After Term. If Lessor elects by written notice to Lessee given no later than 90 days prior to the end of the Lease Term, then following the termination of this Lease, Lessee or its Affiliate will continue to operate the Leased Property after the Term as an operator and not a lessee, pursuant to the Services Agreement and, in such event, Lessee or its Affiliate may elect to use the Leased Property during any such period pursuant to the Gathering Agreement, in each case with such revisions as Lessor and Lessee shall mutually agree (together and with such mutually acceptable revisions, the “Operating Agreements”), for a Monthly Operating Fee equal to the fair market value for applicable services and use under the Operating Agreements as Lessor and Lessee shall negotiate in good faith, for a period of up to two (2) years following the end of the Lease Term, as specified in the notice from Lessor, but subject in any event to the termination rights provided in the Operating Agreements. Upon timely written request from Lessor as provided in this Section 25.2, Lessor and Lessee shall execute and deliver the Operating Agreements and pay or cause to be paid the Monthly Operating Fee in connection therewith.

25.3 Right of First Refusal With Respect to the Transfer of All of the Leased Property.

(a) Limitations on Lessor Transfers. Lessor covenants and agrees that (i) during the ROFR Transfer Period, Lessor shall not Transfer less than all of its right, title or interest in the Leased Property or this Lease, (ii) any Transfer of all of Lessor’s right, title and interest in the Leased Property and this Lease during the Lease Term shall be subject to Section 17.5 and this Section 25.3, and (iii) any Transfer of all of Lessor’s right, title and interest in the Leased Property and this Lease after the end of the Lease Term, but during the remainder of the ROFR Transfer Period, shall be subject to this Section 25.3.

(b) Transfers Subject to ROFR Rights. If at any time or from time-to-time during the ROFR Transfer Period Lessor desires to Transfer or agrees to Transfer all of its right, title and interest in and to the Leased Property and in and under this Lease, in any such case to a Person that is not an Affiliate of Lessor and Lessor has received a Third Party Asset Offer with respect to such Transfer, then (subject to the immediately succeeding sentence of this Section 25.3(b)), Lessor may not consummate such Transfer unless Lessor first complies with the terms and conditions of this Section 25.3. Notwithstanding the foregoing or anything in this Section 25.3 to the contrary, (i) Lessor shall not be permitted to consummate any Transfer of all or any portion of its right, title and interest in and to the Leased Property and in and under this Lease during the Lease Term which is not a Permitted Sale even if Lessee does not elect to exercise its right of first refusal under this Section 25.3 with respect to such Transfer, (ii) the restrictions on Transfers by Lessor under Section 17.5 shall not be applicable to any Transfer of Lessor’s right, title and interest in and to the Leased Property and in and under this Lease after the Lease Term, although the prohibition on partial

Transfers as set forth in subsection (a), above, shall remain applicable during the remaining ROFR Transfer Period, and (iii) this Section 25.3 shall not be applicable, and Lessor shall not be required to comply with this Section 25.3 with respect to a proposed Transfer by Lessor of all or any portion of its right, title and interest in and to the Leased Property and in and under this Lease after the Lease Term if either (A) this Lease has been terminated by Lessor pursuant to Section 23.2(a)(i) as a result of a Level 1 Lessee Default, or (B) as of the end of the Lease Term an Ultra Entity Person is not the Lessee under this Lease. Lessee’s rights under this Section 25.3 are absolute, appurtenant and shall run with the land with respect to the Leased Property and shall survive termination of this Lease for the ROFR Transfer Period.

(c) ROFR Asset Sale Notice. If Lessor desires to accept a Third Party Asset Offer (or if the Third Party Asset Offer is a binding contract that Lessor desires to execute), then Lessor shall provide written notice to Lessee of the Third Party Asset Offer (an “ROFR Asset Sale Notice”). The ROFR Asset Sale Notice will include the following information:

(i) a copy of the Third Party Asset Offer and any related documents (such as an agreed upon form of contract);

(ii) a package containing any information about the Leased Property that Lessor has provided to the proposed buyer;

(iii) an identification of the direct and indirect owners of the proposed buyer (and each Person that will have Controlling Lease Rights) and information as to the business, character, reputation and financial capacity of the proposed buyer and the principals associated therewith to carry out the terms of the Third Party Asset Offer and, during the Lease Term, to comply with all requirements of this Lease and the Equity Investor Agreement in the event such Transfer is consummated; and

(iv) during the Lease Term, such other documents and information as Lessee may reasonably require to evidence that the proposed Transfer will qualify as a Permitted Sale hereunder.

(d) ROFR Asset Offer. The delivery of the ROFR Asset Sale Notice constitutes an offer (an “ROFR Asset Offer”) by Lessor to sell the Leased Property to Lessee in accordance with the terms set forth in this Section 25.3.

(e) Lessee Election. Lessee will have fifteen (15) Business Days from the date of its receipt of the ROFR Asset Offer (the “ROFR Asset Election Period”) to elect to acquire the Leased Property pursuant to the same terms the proposed buyer would acquire the Leased Property under the Third Party Asset Offer. If Lessee desires to acquire the Leased Property pursuant to such terms, then prior to the end of the ROFR Asset Election Period, Lessee must deliver a notice of acceptance (the “ROFR Asset Acceptance Notice”) to Lessor. If Lessee rejects the Third Party Asset Offer or does not timely accept such offer, then Lessor may proceed to close on the Third Party Asset Offer with the proposed buyer in accordance with the substantially unmodified terms of the Third Party Asset Offer only if such Transfer is completed within one hundred fifty (150) days after the last day of the ROFR Asset Election Period. If the terms of such Transfer are modified pursuant to a Material Amendment or such Transfer is not completed within such one hundred and fifty (150) day period, then Lessee shall again have the opportunity to be the buyer under such transaction, meaning that Lessor must send Lessee a new ROFR Asset Sale Notice and comply again with this Section 25.3. At no time during the Lease Term may Lessor elect to Transfer all or any portion of the Lessor Interests or any interest therein except pursuant to a Permitted Sale, whether or not Lessee has elected or rejected the ROFR Asset Offer and any such Transfer by Lessor in violation of this Section 25.3 or Section 17.5 shall be void ab initio. This restriction on Transfer and Lessee’s right of first refusal rights under this Section 25.3 are absolute, appurtenant, and shall run with the land with respect to the Leased Property and this Lease.

(f) Closing. The closing of the purchase of the Leased Property by Lessee under this Section 25.3 will be held within sixty (60) days after the delivery of the ROFR Asset Acceptance Notice or such longer period as required to complete the process described in Subsection (g) below, if applicable. At the closing, Lessor will deliver conveyance documents, each in form and substance contemplated by the Third Party Asset Offer, to transfer the ownership of the Leased Property to Lessee.

(g) Determination of FMV of Non-Cash Consideration. If any part of the consideration to acquire the Leased Property as described in the Third Party Asset Offer is not in cash, then before the end of the ROFR Asset Election Period, Lessee may also elect to have the fair market value of such non-cash consideration (the “Non-Cash Consideration”) determined pursuant to this Section.

(i) Lessor and Lessee will attempt to agree on the Fair Market Value of the Non-Cash Consideration as of the date of the ROFR Asset Offer (the “Non-Cash Consideration Value”). If Lessor and Lessee do not agree within ten (10) Business Days following the ROFR Asset Election Period as to the deemed Non-Cash Consideration Value, then Lessor and Lessee will attempt to agree on an Independent Appraiser to determine such Non-Cash Consideration Value. If Lessor and Lessee agree on such Independent Appraiser on or before fifteen (15) Business Days following the end of the ROFR Asset Election Period, then such Independent Appraiser will determine such Non-Cash Consideration Value on or before thirty (30) Business Days following the end of the ROFR Asset Election Period, which determination will be binding and conclusive on each of Lessor and Lessee. If Lessor and Lessee do not agree on such Independent Appraiser on or before fifteen (15) Business Days following the end of the ROFR Asset Election Period, then Lessee and Lessor will comply with the following procedure to determine the Independent Appraiser and the Non-Cash Consideration Value as of the date of the ROFR Asset Offer:

(ii) On or before twenty (20) Business Days following the end of ROFR Asset Election Period, each of Lessee and Lessor will submit to each other in writing a list of three proposed Independent Appraisers. If either Lessor or Lessee fails to timely provide such list to the other, then the Independent Appraiser will be decided by the other from its list of proposed Independent Appraisers.

(iii) If the name of exactly one proposed Independent Appraiser appears on both the list submitted by Lessor and the list submitted by Lessee, then such Independent Appraiser will be the Independent Appraiser. If the name of more than one Independent Appraiser appears on both the list submitted by Lessor and the list submitted by Lessee, then the proposed Independent Appraiser who appears on both such lists and whose surname is first in an alphabetical list of the proposed Independent Appraisers who appear on both such lists will be the Independent Appraiser. If the name of no proposed Independent Appraiser appears on both the list submitted by Lessor and the list submitted by Lessee, then one proposed Independent Appraiser will be drawn by lot from the six proposed Independent Appraisers by a representative of Lessee in the presence of a representative of Lessor, and the name so drawn will be the Independent Appraiser. Such drawing will occur twenty-five (25) Business Days following the ROFR Asset Election Period.

(iv) The Independent Appraiser, as selected by the process described in this Section, will, within forty (40) Business Days following the end of the ROFR Asset Election Period, (i) determine the Non-Cash Consideration Value as of the date of the Third Party Asset Offer; and (ii) notify in writing Lessor and Lessee of such determination.

(v) The conclusions of the Independent Appraiser as to the Non-Cash Consideration Value as of the date of the Third Party Asset Offer will be binding on each of Lessor and Lessee. The fees and expenses of the Independent Appraiser (and any appraisers engaged by it) will be paid one-half by each of Lessor and Lessee.

(vi) Once the Non-Cash Consideration Value as of the date of the Third Party Asset Offer is determined pursuant to the procedures above and such determination is made known in writing to Lessee, then Lessee will have a right to do any of the following: (A) rescind the ROFR Asset Acceptance Notice (in which event Lessor may proceed under Section 25.3(e) as if the ROFR Asset Acceptance Notice has not been given except that the 150 day period referred to in Section 25.3(e) shall commence as of the date that Lessee elects to rescind the ROFR Asset Acceptance Notice), (B) not rescind the ROFR Asset Acceptance Notice but elect to not pay the Non-Cash Consideration to Lessor and instead pay the Non-Cash Consideration Value to Lessor, or (C) not rescind ROFR Asset Acceptance Notice and pay the Non-Cash Consideration (in addition to the cash consideration as specified in the Third Party Asset Offer) to Lessor. Such election shall be made within ten (10) Business Days after the date the Independent Appraiser advises Lessee and Lessor in writing of the Non-Cash Consideration Value, and if not timely made, Lessee shall be a deemed to have made an election under subsection (A) above.

(a) Limitations on Lessor Lease Transactions. Lessor covenants and agrees that (i) Lessor shall not enter into (A) a Lessor Lease Transaction having a lease term which includes all or any portion of the Lease Term, or (B) at any time during the ROFR Lease Period, any Lessor Lease Transaction with respect to less than all of the Leased Property, (ii) any Lessor Lease Transaction with respect to all of the Leased Property during the Lease Term with a lease term which will begin after the end of the Lease Term shall be subject this Section 25.4, and (iii) any Lessor Lease Transaction during the ROFR Lease Period with respect to all of the Leased Property shall be subject to this Section 25.4.

(b) Lease Transactions Subject to ROFR. If at any time or from time-to-time (i) either (A) during the Lease Term Lessor desires to enter into a Lessor Lease Transaction with a lease term which will begin after the end of the Lease Term, or (B) during the ROFR Lease Period Lessor desires to enter into a Lessor Lease Transaction, in the case of either such subsections (A) or (B) with respect to all or any portion of the Leased Property (the portion of the Leased Property (which may be all of the Leased Property) that Lessor desires to lease is referred to as the “Applicable Leased Assets”) to a Person that is not an Affiliate of Lessor and Lessor has received a Third Party Lease Offer with respect thereto, and (ii) the Lease was or is not terminated by Lessor pursuant to Section 23.2(a)(i) as a result of a Level 1 Lessee Default, and (iii) an Ultra Entity Person was or is the Lessee under this Lease as of the end of the Lease Term, then (I) Lessor may consummate such Lessor Lease Transaction of the Applicable Leased Assets only if Lessor complies with the terms and conditions of this Section 25.4, and (II) Lessor may not enter into a Lessor Lease Transaction within two (2) years after the end of the Term without complying with this Section 25.4. In addition, Lessor shall not enter into a Lessor Lease Transaction which would be subject to this Section 25.4 except for all cash consideration. For the avoidance of doubt, if (X) this Lease is terminated by Lessor pursuant to Section 23.2(a)(i) as a result of a Level 1 Lessee Default, or (Y) as of the end of the Lease Term an Ultra Entity Person was not or is not the Lessee under this Lease, the provisions of this Section 25.4 shall not apply and Lessor may consummate a Lessor Lease Transaction without complying with the terms and conditions of this Section 25.4. This restriction on Lessor Lease Transactions and Lessee’s right of first refusal rights under this Section 25.4 are absolute, appurtenant, shall run with the land with respect to the Leased Property and this Lease, and survive termination of this Lease for the ROFR Lease Period.

(c) ROFR Lease Notice. If Lessor desires to accept a Third Party Lease Offer (or if the Third Party Lease Offer is a binding contract that Lessor desires to execute), then Lessor shall provide written notice to Lessee of the Third Party Lease Offer (a “ROFR Lease Notice”). The ROFR Lease Notice will include the following information:

(ii) a copy of the Third Party Lease Offer and any related documents (such as an agreed upon form of lease); and

(iii) a package containing any information about the Leased Property that Lessor has provided to the proposed lessee, licensee or sublessee; and

(iv) an identification of the principals associated with the proposed lessee, licensee or sublessee under such Third Party Lease Offer and information as to the business, character, reputation and financial capacity of the proposed lessee, licensee or sublessee and the principals associated therewith to carry out the terms of the Third Party Lease Offer.

(d) ROFR Lease Offer. The delivery of the ROFR Lease Notice constitutes an offer (a “ROFR Lease Offer”) by Lessor to lease the Applicable Lease to Lessee in accordance with the terms set forth in this Section 25.4.

(e) Lessee ROFR Election. Lessee will have a period of fifteen (15) Business Days from the date of its receipt of the ROFR Lease Offer (this 15-Business Day period is the “ROFR Lease Election Period”) to elect to enter into the Lessor Lease Transaction pursuant to the same terms the proposed lessee would lease the Applicable Lease Assets under the Third Party Lease Offer (and, to the extent that the Applicable Lease Offer provides for any Non-Cash Consideration, Lessor and Lessee shall apply the same procedures to determine the Non-Cash Consideration Value a is set forth in Section 25.3). If Lessee desires to lease the Applicable Lease Assets pursuant to such terms, then prior to the end of the ROFR Lease Election Period, Lessee must deliver a written notice of acceptance (the “ROFR Lease Acceptance Notice”) to Lessor. If Lessee rejects the Third Party Lease Offer or does not timely accept such offer, then Lessor may proceed to close on the Third Party Lease Offer with the proposed lessee, licensee or sublessee in accordance with the substantially unmodified terms of the Third Party Lease Offer, provided that if such Lessor Lease Transaction does not occur within one hundred fifty (150) days after the date of delivery of the ROFR Asset Acceptance Notice or if the terms of such Lessor Lease Transaction are modified pursuant to a Material Amendment, then Lessee shall again have the opportunity to be the lessee, licensee or sublessee under such Lessor Lease Transaction, meaning that Lessor must send Lessee a new ROFR Lease Notice and comply again with this Section 25.4. Any Lessor Lease Transaction in violation of this Section 25.4 shall be void ab initio. This restriction on Lessor Lease Transactions is absolute, appurtenant, and shall run with the land with respect to the Leased Property.

(f) Closing. A Lessor Lease Transaction of the Applicable Lease Assets by Lessee under this Section (i) will be evidenced by a lease in the form included in and which is a part of the ROFR Lease Notice, but if no such lease form is included in and a part of such ROFR Lease Notice, then in substantially the form of this Lease, revised as necessary or appropriate to conform to the terms of ROFR Lease Notice, and (ii) such lease and any other documents required thereby shall be executed by Lessor and Lessee within thirty (30) days after the date of delivery of the ROFR Lease Acceptance Notice. Notwithstanding the foregoing, Lessor and Lessee agree that no lessee guarantor, lessee guaranty or Resources Guaranty, or lessor guarantor or lessor guaranty shall be required unless as and to the extent required by the ROFR Lease Notice.

(a) Burdensome Buyout Notice. At any time and from time-to-time, upon the occurrence and during the continuance of a Burdensome Event, Lessee shall have the option, but not the obligation, to provide written notice (the “Burdensome Buyout Notice”) to Lessor proposing a termination of this Lease and offering to purchase all of the Leased Property as provided in this Section 25.5 for the purchase price as specified by Lessee in such Burdensome Buyout Notice.

(b) Burdensome Buyout Response Notice. If Lessee delivers its Burdensome Buyout Notice to Lessor, then Lessor shall have a period of no more than fifteen (15) days in which to either notify Lessee in writing of Lessor’s acceptance or rejection of Lessee’s Burdensome Buyout Notice (“Burdensome Buyout Response Notice”). Lessor’s failure to provide its Burdensome Buyout Response Notice within such fifteen (15) day period shall be deemed a rejection of Lessee’s Burdensome Buyout Notice and the Lease shall continue in effect.

(c) Termination of Lease. If Lessor accepts the Burdensome Buyout Notice, (i) this Lease shall terminate on a date no later than sixty (60) days after the Burdensome Buyout Response Notice specified in the Burdensome Buyout Notice and this Lease shall terminate on such date (the “Burdensome Buyout Lease Termination Date”), (ii) except as provided in Sections 25.2, 25.3 and 25.4, and the other terms and provisions of this Lease which survive termination, neither Lessor nor Lessee shall have any rights or obligations under this Lease arising from and after the Burdensome Buyout Lease Termination Date, (iii) no further Base Rent or Additional Rent shall accrue with respect to the period after the Burdensome Buyout Lease Termination Date, (iv) Lessee shall have no obligation to take any Corrective Action with respect to the circumstances giving rise to the Burdensome Event, (v) neither Lessor nor any other Lessor Indemnified Party shall have any claim against Lessee with respect to any Corrective Action with respect to the circumstances giving rise to the Burdensome Event, or Losses arising from termination of this Lease or Lessee’s purchase of the Leased Property pursuant to this Section 25.5, (vi) all Lessee Guarantors shall be released of liability and obligations under their Lessee Guarantees, Ultra Resources shall be released of liability and obligations under the Resources Guaranty and all Lessor Guarantors shall be released of liability and obligations under their Lessor Guarantees with respect to (x) as to Lessee Guarantors and Ultra Resources only, matters for which Lessee is released in subsections (iv) and (v), preceding, and (y) matters arising or accruing from and after the Burdensome Buyout Lease Termination Date, it being understood and agreed, however, that Lessee Guarantors, Ultra Resources and Lessor Guarantors shall remain liable with respect to matters or claims arising or accruing prior to the Burdensome Buyout Lease Termination Date except those matters described in subsections (iv) and (v), preceding, and (vii) if the circumstances giving rise to such Burdensome Event include a casualty or a Taking, then the Casualty Proceeds or the Taking Proceeds, as applicable, shall be paid to Lessee.

(d) Closing of Purchase Offer. If Lessor accepts the Burdensome Buyout Notice, on the Burdensome Buyout Lease Termination Date (i) Lessee shall pay to Lessor the purchase price specified by Lessee in the Burdensome Buyout Notice or such other purchase price as Lessor and Lessee mutually agree, (ii) Lessor shall convey the Leased Property to Lessee or its designee on an AS IS WHERE IS basis, without any express or implied warranties from Lessor other than special warranties of title, provided, however, that such conveyance shall in any event be made by Lessor to Lessee or its designee free and clear of (A) all Permitted Lessor Liens, (B) any other Liens placed on the Leased Property by, through or under Lessor, and (C) any Other Recorded Documents executed by, through or under Lessor in violation of this Lease, and (iii) Lessor will deliver to Lessee or its designee such conveyance documents, each in form and substance reasonably satisfactory to Lessee, as Lessee may reasonably request, to transfer the ownership of the Leased Property to Lessee free and clear of the Liens and other items described in subsections (A)-(C) above.

(e) Continuation of Lease if Lessor Rejects Lessee’s Burdensome Buyout Notice. If Lessor rejects or is deemed to have rejected Lessee’s Burdensome Buyout Notice, such Burdensome Buyout Notice with respect to termination of the Lease and Lessee’s offer to purchase the Leased Property shall be deemed to be automatically rescinded and this Lease shall remain in full force and effect in accordance with its terms.

(f) No Waiver. Upon each occurrence of a Burdensome Event, Lessee shall be entitled to give its Burdensome Buyout Notice with respect to such Burdensome Event, even if Lessee previously elected not to give such notice with respect to the occurrence of a prior Burdensome Buyout and even if Lessee’s prior Burdensome Buyout Notice(s) were rejected by Lessor hereunder.`

25.6 Application of Certain Right of First Refusal Rights to a Foreclosure Sale. Notwithstanding anything to the contrary herein, Lessee’s right of first refusal rights under Section 25.3 hereof shall not be applicable to a Transfer of the Leased Property made pursuant to a foreclosure or deed in lieu of foreclosure with respect to a Permitted Lessor Lien. For the avoidance of doubt, Lessee’s rights under both Section 25.3 and 25.4 shall survive any foreclosure sale or deed in lieu of foreclosure or similar conveyance with respect to the Leased Property and this Lease.

26.1 Memorandum/Notice of Lease. Simultaneously with the execution of this Lease, Lessor and Lessee shall execute and deliver the Memo of Lease and cause it to be recorded in the Official Public Records. Upon termination of this Lease, upon the request of either party, the other party will execute an instrument in recordable form indicating that this Lease has been terminated. No mortgages, deeds of trust, fixture filings, UCC financing statements or other Lien filings will be recorded by Lessor or any Lessor Lender in the Official Public Records or in personal property UCC records naming Lessee as a debtor with respect to any of the Leased Property.

26.2 Force Majeure. If either party shall be delayed or hindered in, or prevented from, the performance of any act required under this Lease by reason of strikes, lockouts, labor troubles, riots, insurrection, war or other reasons of a like nature beyond the reasonable control of the party delayed in performing work or doing acts required under the terms of this Lease (any such delay, hindrance or prevention being referred to as “Force Majeure”), then performance of such act shall be excused for the period of delay, and the period of the performance of any such act shall be extended for a period equivalent to the period of such delay unless otherwise specifically provided to the contrary in this Lease. The provisions of this Section shall not apply to delays in the payment of amounts due and owing by Lessee or Lessor hereunder or resulting from the inability of a party to obtain financing or to satisfy its obligations under this Lease because of a lack of funds.

26.3 Consequential Damages. Notwithstanding anything in this Lease to the contrary, in no event shall Lessor or Lessee be liable or responsible for (a) consequential, punitive, special or indirect damages, or loss of profits, or (b) except to the extent not excluded from “Losses” in the definition of such term in this Lease, diminution in value under this Lease, and including with respect to both subsections (a) and (b), any holding over by Lessee under Section 26.4 of this Lease.

26.4 Holding Over. Except for continuations of Lessee’s occupancy after the Lease Term pending determination of rent for a Renewal Term as provided in Section 25.1(e), if Lessee remains in possession of any Leased Property after the expiration of the Term without having timely executed its right, if any, to extend the Term, such continuing possession shall create a month to month tenancy on the terms of this Lease except that the monthly Base Rental shall be 125% of the Base Rent applicable as of the end of the Term, and such tenancy may be terminated at the end of any month thereafter by either party giving at least sixty (60) days’ notice to the other party.

26.5 Quiet Enjoyment. Lessor agrees that so long as this Lease is in effect, Lessee shall and may peaceably and quietly have, hold and enjoy the Leased Property and all rights of Lessee hereunder during the Term without any manner of hindrance or molestation from Lessor, Lessor Lender, or anyone claiming by, through or under Lessor or Lessor Lender.

26.6 Cost and Expense. Wherever it is provided in this Lease that an act is to be undertaken by any Person, such act shall be done by such Person or caused to be done by such Person at no cost or expense to the other party, other than any de minimus cost or expense, unless a contrary intent is expressed.

(a) Access and Inspection Rights. Lessor and Lessor Lender (or the Agent for such Lessor Lender if requested in writing by Lessor) may, at their sole cost and expense, inspect the Leased Property during normal business hours at such locations where the same is located or kept in Lessee’s ordinary course of business, after not less than five (5) Business Days prior notice to Lessee; provided, however, neither Lessor, any Lessor Lender nor any Agent for any Lessor Lender shall have any right to inspect any of the Leased Property without a representative of Lessee being present and Lessor and Lessor Lender (or its Agent, if applicable) shall abide by Lessee’s reasonable rules and regulations (including those governing matters of health and safety) when making such inspections; provided, further, that, unless (i) Lessee’s interest under this Lease has been assigned to a Person that is not a Permitted Lessee Transferee or (ii) a Level 1 Lessee Default has occurred and is continuing, and excluding inspections made with respect to restorations following a casualty or condemnation as such inspections are permitted by and pursuant to Article XV or Article XVI, Lessor Lender (or the Agent for such Lessor Lender if requested in writing by Lessor) may inspect the Leased Property no more frequently than once per calendar year and Lessor may inspect the Leased Property no more frequently than twice per calendar year. Lessee shall use commercially reasonable efforts to cause its representative to be present for Lessor’s inspection when notice is given as required by this subsection (a). In the event Lessee is unable to provide a representative of Lessee to be present for a Lessor or Lessor Lender inspection at any time during a thirty (30) consecutive day period, Lessee shall pay to Lessor a $10,000 penalty. Under no circumstances shall Lessor permit its inspection or any inspection by Lessor Lender (or the Agent for such Lessor Lender if requested in writing by Lessor) to interfere with Lessee’s ordinary operation of the Leased Property or with Lessee’s business. Under no circumstances may Lessor or Lessor Lender permit any Disqualified Persons to inspect the Leased Property; provided, however, that if Lessee has not elected to renew this Lease beyond the Current Lease Term End, then commencing the last day on which the Renewal Option may be exercised, Lessor may allow a potential purchaser or replacement lessee of all or any part of the Leased Property (including a Disqualified Person) to accompany it in an inspection conducted under this Section, provided that any such Person shall execute a confidentiality agreement containing the restrictions on disclosure herein set forth prior to any such inspection. Lessor acknowledges and stipulates that Lessee may suffer irreparable harm in the event of a breach of the provisions of this Section 26.7(a) for which Lessee has no adequate remedy at law. Therefore, in addition to all other remedies available pursuant to the terms of this Lease or at law, Lessee shall have the right to obtain immediate injunctive or other equitable relief upon a breach of this Section 26.7(a).

(i) furnish, not later than 60 days after the end of each calendar month during the Term, a report stating the Actual Daily Product Volume for such prior month;

(ii) use its commercially reasonable efforts to provide to Lessor the financial statements and Audit Report provided for in paragraphs (iii), (iv) and (v) of this Section prior to the date such financial statements must be filed by Lessor or Lessor Guarantor with the Securities and Exchange Commission, and will provide Lessor its best estimate of the dates on which Lessee Guarantor plans to file its Forms 10-K and Forms 10-Q with the Securities and Exchange Commission at least five days prior to any such filing date;

(iii) not later than the date on which a large accelerated filer (as defined in the rules of the Securities and Exchange Commission) with a fiscal year ending on December 31 is required to file its Form 10-K with the Securities and Exchange Commission, including any extension permitted by Rule 12b-25 of the Exchange Act, cause Lessee Guarantor (or, if there is no Lessee Guarantor, then Lessee) to furnish to Lessor such Person’s audited consolidated balance sheet and related statements of operations, stockholders’ equity and cash flows as of the end of and for such its most recently completed fiscal year, as well as related footnotes;

(iv) not later than the date on which a large accelerated filer with a fiscal year ending December 31 is required to file its Form 10-Q with the Securities and Exchange Commission, including any extension permitted by Rule 12b-25 of the Exchange Act, cause Lessee Guarantor (or, if there is no Lessee Guarantor, then Lessee) to furnish to Lessor such Person’s unaudited consolidated balance sheet and related statements of operations, stockholders’ equity and cash flows as of the end of and for its most recently completed fiscal quarter, as well as related footnotes;

(v) If Lessor has advised Lessee in writing that Lessor or Lessor Guarantor is required to file an Auditor’s Report with respect to Lessee Guarantor’s (or Lessee’s) financial information delivered under Section 26.7(b)(iii), in filings to be made by Lessor or Lessor Guarantor with the Securities and Exchange Commission, then Lessee or Lessee Guarantor shall use commercially reasonable efforts to cause its auditor to provide the Auditor’s Report at the sole cost and expense of Lessor and Lessor Guarantor (which costs and expenses will be reimbursed by Lessor and Lessor Guarantor within 30 days of receiving an invoice for such costs and expenses from Lessee or Lessee Guarantor); and

(vi) provide prompt written notice to Lessor of any failure by Lessee or Lessee Guarantor to pay any installment of principal or interest under its Material Debt when due if such failure is not cured or waived within the applicable grace period with respect to such Material Debt.

(c) Financial statements, reports and other information required or permitted to be furnished by Lessee or Lessee Guarantor pursuant to this Lease, including the financial statements and other information furnished pursuant to this Section 26.7(b)(iii) and (iv), may be submitted by Lessee or Lessee Guarantor by email addressed to Lessor. In the event that any information or documents furnished by Lessee or Lessee Guarantor pursuant to this Lease is publicly available on the Securities and Exchange Commission EDGAR database (or any successor database), such documents or information shall be deemed to have been delivered to Lessor by Lessee on the date on which Lessee or Lessee Guarantor files such financial statements or other information with the Securities and Exchange Commission and provides notice to Lessor of such filing, which notice may be given by email. In addition, Lessor agrees that if the issuer of the financial statements required to be delivered by paragraphs (iii) and (iv) of this Section is not a large accelerated filer, or has a fiscal year other than December 31^st, the Lessor and Lessor Guarantor will cooperate in good faith with the Lessee, including making appropriate request of the staff of the Securities and Exchange Commission, to permit the issuer required to provide such financial statements to do so on a schedule proposed by such issuer and reasonably acceptable to the Lessee, provided that such schedule is approved by the staff of the Securities and Exchange Commission.

(d) Periodic Discussions. In addition to the reports and statements to be delivered by Lessee pursuant to Section 26.7(b), Lessor and Lessee agree, within fifteen (15) Business Days after the end of each calendar quarter during the Term, to convene a conference call with at least one Responsible Officer of each party to discuss the operations and financial performance of the Liquids Gathering System, the reports and statements delivered by Lessee pursuant to Section 26.7(b) and other relevant information regarding the Leased Property, provided, however, that the Responsible Officers of Lessee may delegate participation in such calls to other representatives of Lessee who are appropriate to participate in discussions of the operation and performance of the Liquids Gathering System.

(a) Lessor. Acceptance by Lessor of any partial payment of any amount payable by Lessee hereunder shall not constitute an accord and satisfaction by Lessor of any of Lessee’s obligations hereunder and Lessor shall be entitled to collect from Lessee the balance of any amount remaining due.

(b) Lessee. Acceptance by Lessee of any partial payment of any amount due from Lessor hereunder shall not constitute an accord and satisfaction by Lessee of any of Lessor’s obligations hereunder and Lessee shall be entitled to collect from Lessor the balance of any amount remaining due.

26.9 Prevailing Party. If any action at law is necessary to enforce or interpret the terms of this Lease, the prevailing party shall be entitled to reasonable attorneys’ fees and costs of the proceeding up to and including all trial and appellate levels in addition to any other relief to which it may be entitled. If any action in equity is necessary to enforce or interpret the terms of this Lease, the prevailing party shall be entitled to reasonable attorneys’ fees and costs up to and including all trial and appellate levels in addition to any other relief to which it may be entitled. For purposes of this Section, a party will be considered to be the “prevailing party” if (a) such party initiated the litigation and substantially obtained the relief which it sought (whether by judgment, voluntary agreement or action of the other party, trial, or alternative dispute resolution process), (b) such party did not initiate the litigation and either (i) received a judgment in its favor, or (ii) did not receive judgment in its favor, but the party receiving the judgment did not substantially obtain the relief which it sought, or (c) the other party to the litigation withdrew its claim or action without having substantially received the relief which it was seeking.

(a) General Confidentiality Provisions. Lessor shall, and shall cause any Person receiving Proprietary Information or other Confidential Information directly or indirectly from Lessor, to hold all Proprietary Information and other Confidential Information in strict confidence. Subject to subsection (b), below, (i) Lessor may disclose Proprietary Information and other Confidential Information only to the Lessor Parent, Lessor Lenders and prospective Lessor Lenders, holders of Lessor Equity Interests and prospective holders of Lessor Equity Interests, and any prospective purchaser of the Leased Property and, on a need to know basis, to their respective Affiliates, directors, officers, employees, accountants, legal counsel and other advisors who are involved in the administration, analysis and accounting for this Lease, and (ii) in the event Lessee is no longer the operator of the Leased Property, Lessor may disclose to a successor operator of the Liquids Gathering System and its advisors and consultants the Records and such other portions of the Proprietary Information and other Confidential Information as are necessary or prudent to permit them to safely and effectively manage and operate the Leased Property, provided that in the case of both subsections (i) and (ii), Lessor shall be responsible for the compliance by each such Person to whom disclosure is made with the confidentiality provisions of this Section 26.10 (including the acknowledgments and stipulations under subsection (c) of this Section), and Lessor shall remain liable for any breach of the provisions of this Section by any such Person. Notwithstanding the foregoing, Lessor shall not be responsible for any failure by Ross Avenue Investments, LLC, the limited partner of Pinedale Corridor, LP, to comply with the confidentiality requirements of this Section 26.10(a) so long as Ross Avenue Investments, LLC, is in full compliance with Exhibit D to the Equity Investor Agreement dated of even date with this Lease. Neither Lessor nor any Person to whom disclosure is made pursuant to this subsection (a) may disclose Proprietary Information or other Confidential Information to any other Person or entity except (A) to the extent required by any regulatory authority, (B) to the extent required by applicable laws or regulations or by subpoena or similar legal process, in each case after adequate notice to Lessee in order to allow Lessee to seek a protective order or other protection therefor, (C) with the prior written consent of Lessee, (D) to the extent such information becomes publicly available other than as a result of a breach of this Section, or (E) to the extent disclosure of such Proprietary Information or other Confidential Information by CorEnergy Infrastructure Trust, Inc. (or any successor Lessor Parent) is necessary or appropriate pursuant to the provisions of the federal securities laws or the rules or regulations promulgated thereunder. For the avoidance of doubt, nothing contained in this Section 26.10 shall limit the ability of Lessee or any of its Affiliates to disclose Proprietary Information or other Confidential Information.

(b) Special Restrictions Regarding Proprietary Information. Notwithstanding anything to the contrary set forth in this Section 26.10 or elsewhere in this Lease, no Proprietary Information may, under any circumstance at any time during this Lease or following its termination, be (i) disclosed to any Person who, at the time of such disclosure, is a Disqualified Person, or (ii) disclosed in any document, agreement or exhibit filed pursuant to the federal securities laws or any rules or regulations promulgated thereunder.

(c) Survival, Specific Performance and Equitable Remedies. The obligations under this Section 26.10 of Lessor, and of all Persons to whom Confidential Information or Proprietary Information is disclosed, shall survive the expiration and termination of this Lease. Lessor acknowledges and stipulates (and all Persons to whom Confidential Information or Proprietary Information is disclosed shall be deemed to acknowledge and stipulate) that Lessee may suffer irreparable harm in the event of a breach of the provisions of this Section 26.10 by Lessee, or by a disclosure of Confidential Information or Proprietary Information by any other Person to whom Confidential Information or Proprietary Information is disclosed hereunder, in each case for which Lessee has no adequate remedy at law. Therefore, in addition to all other remedies available pursuant to the terms of this Lease or at law, Lessee shall have the right to obtain immediate injunctive or other equitable relief upon a breach of this Section 26.10 by Lessor or any other Person to whom Confidential Information or Proprietary Information is disclosed.

26.11 Consent of Lessor and Lessee. Unless specified otherwise herein and except for consents or approvals for which a specific standard is expressly set forth herein (such as “not unreasonably withheld”, “sole discretion”, etc.) and specific provisions which describe the issues which may be considered when making or withholding approval (Permitted Lessee Transferee, etc.), Lessor’s consent to any request of Lessee shall not be unreasonably withheld, conditioned, or delayed and Lessee’s consent to any request of Lessor shall not be unreasonably withheld, conditioned, or delayed.

26.12 Permitted Lessee Contests. Lessee shall not be required to pay any cost, expense or charge or perform any obligation so long as Lessee contests in good faith and at its own expense the amount or validity thereof by appropriate proceedings which shall operate to prevent the collection thereof or realization thereon and the sale, foreclosure or forfeiture of the Leased Property or any part thereof to satisfy the same, and Lessee shall have furnished any security as may be required in the applicable proceeding, and, pending any such proceedings, Lessor shall not have the right to pay or perform the same. In no event shall the manner in which Lessee pursues any such contest exacerbate in any material respect the risk to Lessor of civil or criminal liability, penalty or sanction, in addition to such risks as may exist for the matters that are the subject of such contest prior to such contest, and except for liabilities, penalties or sanctions for which Lessee may, and in fact does, post a bond. Further, the manner in which Lessee pursues any such contest shall not exacerbate in any material respect the risk to Lessor of defeasance of its interest in the Leased Property in addition to the risk of such defeasance as may exist for the matters that are the subject of such contest prior to such contest and except for such risk which Lessee may, and in fact does, bond around. Lessee shall use commercially reasonable efforts to diligently prosecute any such contest to a final conclusion, except that Lessee shall have the right to attempt to settle or compromise such contest through negotiations and to discontinue any such contest at any time. Lessee shall promptly after the final determination of such contest, fully pay any amounts determined to be payable thereon and/or fully perform any obligations to be performed thereon, together will all penalties, fines, interest, costs and expenses resulting from such contest. Upon Lessee’s request, Lessor shall prosecute such contest, if required by Applicable Legal Requirements, at no cost or expense to Lessor other than de minimus cost or expense. Upon reasonable request of Lessor at any time or from time-to-time, Lessee shall provide a written report to Lessor regarding the status of any such contests.

26.13 Waiver. Failure of either party to complain of any act or omission by the other party, no matter how long the same may continue, shall not be deemed to be a waiver by the party of any of its rights hereunder. No waiver by either party at any time, whether express or implied, of any breach of any provision of this Lease shall be deemed a waiver of a breach of any other provision of this Lease or a consent to any subsequent breach of the same or any other provision. All rights and remedies which either party may have under this Lease or by law upon a breach hereunder shall be distinct, separate and cumulative and shall not be deemed inconsistent with each other. Except as and to the extent this Lease provides that certain rights or remedies are limited or exclusive, no right or remedy, whether exercised by a party or not, shall be deemed to be in exclusion of any other right or remedy and any two (2) or more or all of such rights and remedies may be exercised at the same time, but without duplication of recovery for any such matter.

26.14 Interpretation. If any provision of this Lease or the application of any provision to any Person or any circumstance shall be determined to be invalid or unenforceable, then such determination shall not affect any other provision of this Lease or the application of such provision to any other Person or circumstance, all of which other provisions shall remain in full force and effect. It is the intention of the parties that if any provision of this Lease is capable of two constructions, one of which would render the provision void and the other of which would render the provision valid, the provision shall have the meaning which renders it valid. This Lease shall be interpreted and enforced without the aid of any canon, custom or rule of law requiring or suggesting construction against the party drafting or causing the drafting of the provision in question.

26.15 No Derivative Liability. Notwithstanding anything set forth in this Lease or otherwise, no direct or indirect (through tiered ownership or otherwise) advisor, trustee, director, officer, employee, beneficiary, shareholder, participant, partner, member, owner, investor, representative or agent of a party or its applicable Affiliates shall have any personal liability, directly or indirectly, under or in connection with this Lease, the Lessee Guaranty, the Resources Guaranty or the Lessor Guaranty or any amendment or amendments to any of the foregoing made at any time or times, heretofore or hereafter, and the other party and its successors and assigns and, without limitation, all other persons and entities, shall look solely to the assets of such party or its applicable Affiliates for the payment of any claim or for any performance, and each other party, on behalf of itself and its successors and assigns, hereby waive any and all such personal liability. Nothing in this Section 26.15 is intended or shall be deemed to impair or limit the liability of any Person under any Lessor Guaranty, any Lessee Guaranty, the Resources Guaranty or any Guaranty Agreement executed and delivered in connection with the Purchase Agreement or the liability of any Equity Investor or Lessor Parent under the Equity Investor Agreement.

26.16 Successors and Assigns. The words “Lessor” and “Lessee” and the pronouns referring thereto, as used in this Lease, shall mean where the context requires or admits, the Persons named herein as Lessor and as Lessee respectively, and (subject to the provisions hereof prohibiting certain Transfer, leases, subleases, assignments and Liens) their respective successors and assigns, irrespective of whether singular or plural, masculine, feminine or neuter. The agreements and conditions to be performed by Lessor shall be binding upon Lessor and its successors and assigns and shall inure to the benefit of Lessee and its successors and assigns, and the agreements and conditions to be performed by Lessee shall be binding upon Lessee and its successors and assigns and shall inure to the benefit of Lessor and its successors and assigns.

26.17 No Offer; Entire Agreement. This Lease is transmitted for examination only and does not constitute an offer to lease and shall become effective only upon execution and unconditional delivery by Lessor and Lessee and delivery of the Lessor Guaranty, the Lessee Guaranty and the Resources Guaranty required hereby. This instrument, the Purchase Agreement, the SNDA and the Equity Investor Agreement contain the entire and only agreement between the parties, and no oral statements or representations or prior written matter not contained in this Lease or any such other documents shall have any force or effect. This Lease shall not be modified in any way except by a writing subscribed by both parties.

26.18 Headings. The headings for the various articles and sections of this Lease are used only as a matter of convenience for reference and are not to be considered a part of this Lease or used in determining the intent of the parties to this Lease.

26.19 Counterparts. This Lease may be executed in one or more counterparts, any one or all of which shall constitute one and the same instrument.
