Seller agrees to assign to Buyer all rights, claims, and causes of action on title warranties given or made by Seller’s respective predecessors, and that Buyer is specifically subrogated to all rights which Seller may have against its predecessors, to the extent that Seller may legally transfer such rights and grant such subrogation. Section 3.2 Consents. (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 7

changes to such form as may be required by changes in applicable law or regulations after the Execution Date. Buyer shall pay any costs or expenses assessed by BLM in connection with such BLM Request for Consent to Assignment to Buyer, and Seller shall not be obligated to incur any out-of-pocket expenses or obligations to obtain the BLM Consent. (b) Except for the BLM Consent, 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, an “Additional Required Consent”) such Party shall promptly notify the other of the need for such Additional Required Consent, the Seller and Buyer shall use commercially reasonable efforts to obtain such Additional Required Consent. 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 3.2 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 shall pay any costs or expenses incurred to obtain any Additional Required Consent (which for the avoidance of doubt, does not include any consents under the Loan Documents); provided, however, that in no event shall Buyer be responsible for any out-of-pocket attorney’s fees incurred by Seller with respect to any Additional Required Consent.

(b) To Seller’s Knowledge, there are not pending any, and Seller has received no written notice of any currently proposed, material adjustments by any Taxing Authority in connection with any Tax Returns relating to the Assets which if unpaid would result in the filing 9

Notwithstanding anything herein to the contrary, assuming Closing occurs on or prior to the Outside Closing Date, Buyer shall not be responsible for rental payments to Seller under the LGS Lease from and after June 30, 2020.

Buyer and Seller agree that they will not take any Tax position inconsistent with allocations made in this Agreement, if any, provided, however, that (a) Buyer’s cost for the Assets may differ from the total amount allocated thereunder to reflect Buyer’s capitalized transaction costs so allocated, and (b) Seller’s amount realized on the sale of the Assets may differ from the total amount so allocated to reflect Seller’s transaction costs that reduce the amount realized.

(c) All liability or obligation of any Party with respect to any indemnity or other obligation contained in Section 11.1 or Section 11.2(a), or (b) of this Agreement shall lapse and be of no further force or effect with respect to any matters not described in reasonable detail in a Claim Notice delivered to such Party by the other Party on or prior to the end of the applicable period described in Section 11.3(a) or (b).

The indemnifications contained in this Article XI 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, or the Indemnifying Party waives its right to protest the Claim. Any undisputed portion of the Claim must be paid within 30 days of receipt of the Claim Notice. 19

(b) Information. Within 60 days after the Indemnified Party receives notice of a claim or legal action by a third party 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 XI 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. Section 11.5 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. Section 11.6 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. Section 11.7 Consequential Damages. Notwithstanding anything set forth in this Agreement, Buyer and Seller, on behalf of themselves and their respective Affiliates, expressly waive any and all rights to consequential, special, incidental, punitive, or exemplary damages and loss of profits resulting from a breach of this Agreement, including under or with respect to any indemnifications required hereby, and agree that the indemnifications set forth herein shall not include or cover any consequential, special, incidental, punitive, or exemplary damages or loss of profits (except to the extent constituting direct damages). Nothing in this Section 11.7 shall constitute a waiver by any Party to a claim under this Article XI with respect to diminution in value to the extent diminution in value is expressly included in the definition of the “Losses” covered by the Section of this Article under which the claim is made. 20

Section 11.8 No Derivative Liability. Notwithstanding anything set forth in this Agreement, the Closing Deliveries or otherwise, no direct or indirect (through tiered ownership or otherwise) advisor, trustee, director, officer, employee, beneficiary, shareholder, participant, partner, member, owner, investor, lender, representative or agent of a Party or its applicable Affiliates shall have any personal liability, directly or indirectly, under or in connection with this Agreement or any Closing Deliveries 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, if expressly applicable, the assets of such Party’s Affiliate) 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. Section 11.9 Attorneys’ Fees. If it shall be necessary for any Party to this Agreement to employ an attorney to enforce its rights pursuant to this Agreement, the non-prevailing Party shall reimburse the prevailing Party for its reasonable attorneys’ fees and the reasonable attorneys’ fees of the prevailing Party’s applicable Affiliates, if any, in such proceeding. ARTICLE XII MISCELLANEOUS Section 12.1 Expenses. Except as otherwise specifically provided, all fees, costs and expenses incurred by Buyer or Seller in negotiating this Agreement or in consummating the Transaction shall be paid by the Party incurring the same, including without limitation, engineering, land, title, legal and accounting fees, costs and expenses. This Section 12.1 shall survive termination of this Agreement and Closing. Section 12.2 Notices.

Any Notice shall be deemed to have been duly made and the receiving Party charged with notice (a) if personally delivered, or sent by registered or certified mail, or nationally recognized overnight courier, when received; (b) if sent by electronic transmission (with read receipt requested); and (c) 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; provided, however, that if a Notice is sent by electronic transmission, the party sending the Notice also must send, on the same date, a confirmation copy of the Notice (including the acknowledgement/transmission report described above) by one of the other methods set forth in this Section.
