Dear Neighbor:

Chesapeake Exploration, L.L.C. (“Chesapeake”) is pleased to announce that we have recently reached an agreement with the Northeast Tarrant Gas Leasing Organization (“NETGLO”) Committee regarding the mineral development of your neighborhood. This important agreement comes as a result of months of negotiations and presents a very attractive leasing opportunity for the members of the NETGLO Community. Please take a moment to review this letter, as the endorsed agreement is customized to the individual landowners and involves multiple legal documents.

Every landowner will receive four documents, which are endorsed by the Committee and approved by the Neighborhoods legal counsel: (1) the Oil and Gas Lease form; (2) a Memorandum of Oil and Gas Lease; (3) a W9 Tax form, and (4) an Authorization Form to Request Subordination/Non-Disturbance Agreement.

Subject to final verification of title and contracts related to this transaction.

Please review our list of signing dates enclosed with this letter. We ask that you attend the meeting date corresponding with your property in order to expedite the process.

Due to the large number of homes and lessors involved in the NETGLO area, Chesapeake has retained Petrocasa Energy (Petrocasa) and Harding Energy Partners (HEP) as our independent contractors authorized to exclusively acquire leases in the NETGLO area on our behalf. There will be Petrocasa representatives present to assist in answering any questions you might have, and to facilitate the execution of the aforementioned lease documents. Petrocasa will prepare your personalized lease documents in advance of the meeting, and those documents will be on-hand at the meeting times shown on the attachment.

Please bring a photo ID, and if married, please have your spouse attend the meeting as well. If possible, please have your Social Security and mortgage information available in order to complete the lease package. Be assured we will do everything we can to make the signing of your lease hassle-free and convenient.

If you are unable to make it to your scheduled meeting or have any further questions or concerns please feel free to contact Petrocasa at (817) 820-0288 or via email at NETGLO@petrocasa.com.
