(c)Spacing of Wells.  ARP Purchaser and AGP Purchaser will cooperate to comply with the spacing regulations applicable to the Existing Units; provided, however, that in no event shall either of such Parties request Contract Operator to drill any well within 165 feet of any border between any of the ARP Purchaser Ownership Area and any of the AGP Purchaser Ownership Area without the prior written consent of each other Party.

8.2Rights of Way. Each Party hereby grants, and shall cause its Subsidiaries to grant, to each other Party a non-exclusive right (to the extent such right is transferable, and each Party shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to obtain consents to transfer such right if it is transferrable with consent) for no consideration to use any surface fee interests, surface leases, sub-surface easements, easements, rights-of-way, licenses, servitudes, or other surface real property rights within such Party’s portion of the Assets (collectively, the “Rights of Way”) as necessary to allow the Parties to conduct oil and gas operations with respect to the Assets in accordance with this Agreement, but only to the extent such use or access does not unreasonably interfere with the existing operations of or use by the Party or such Party’s Subsidiaries that hold such Rights of Way, and subject in all cases to (a) the express terms, conditions, obligations and limitations set forth in the documents or instruments establishing such Rights of Way, (b) applicable Law relating to the Rights of Way areas or the use thereof, (c) any right of access or use (and any such access or use) of any co-owner of such Rights of Way existing on the Closing Date or existing as of the date of acquisition of such Rights of Way, and (d) any contractual obligation existing on the Closing Date that the Party holding such Rights of Way may have to convey or provide use of Rights of Way to the Party.  Rights to Rights of Way granted under this Section 8.4 shall terminate upon the termination of this Agreement.

8.3Joint HBP Units.  

(a)Each of ARP Purchaser and AGP Purchaser shall provide to the other Party, no later than 10 days following the end of each month, a written report identifying each well in which the notifying Party owns an interest that (i) is located within the boundaries of a pooled oil and gas unit memorialized by a Pooling Agreement in which the other Party also owns an interest in the same unit (each, a “Joint HBP Unit”), and (ii) has average daily liquid hydrocarbon production in the prior month of less than five barrels/day.  Each such report shall identify the relevant Joint HBP Unit, the well names and the average daily production for the prior month for each such well.

(b)If a well is holding a Joint HBP Unit by production (each such well, a “Subject Well”) and the Party that owns an interest in such Subject Well (the “Subject Well Owner”) makes a determination to abandon or permanently shut in such Subject Well or determines that such Subject Well is no longer producing in sufficient quantities to continue holding the applicable Joint HBP Unit by production, the Subject Well Owner shall promptly

-13-

provide the other Party who owns an interest in the Joint HBP Unit written notice of such determination.  Within 45 days of such notice, such other Party shall have the right, to the extent permitted by the applicable Pooling Agreement, as may be amended, to take over such Subject Well and receive an assignment of the remainder of the unit and the associated leasehold interest (or partial leasehold interest) held by the Subject Well Owner, in each case for no additional consideration by delivering to the Subject Well Owner an irrevocable written notice of such election (the date of such written notice being the “Assignment Effective Date”).  Within ten days after the Assignment Effective Date, the Subject Well Owner shall deliver an assignment and bill of sale for the Subject Well and the remainder of the acreage within the Joint HBP Unit, effective as of the Assignment Effective Date.  Upon receipt of the assignment and bill of sale from the Subject Well Owner, the other Party who owns an interest in the Joint HBP Unit will be deemed to have acquired the Subject Well and the Subject Well Owner’s associated leasehold interest in the Joint HBP Unit as of the Assignment Effective Date together with all rights, responsibilities, assets and liabilities of the Subject Well Owner associated with or arising from such Subject Well and the assignment of the interests therein, including associated plugging, abandonment, restoration, reclamation, environmental, lessee and other liabilities of any kind or character.
