LIMITED WAIVER AND CONSENT

Exhibit 4.4.1

LIMITED WAIVER AND CONSENT

RECITALS:

Reference is made to that certain Seventh Amended and Restated Credit Agreement dated as of November 2, 2007 (the “ Agreement ”), among Chesapeake Energy Corporation (“ CEC ”), Chesapeake Exploration, L.L.C. (“ Chesapeake Exploration ”) and Chesapeake Appalachia, L.L.C. (“ Chesapeake Appalachia ”, and together with Chesapeake Exploration, collectively, “ Borrowers ”), Union Bank of California, N.A., as Administrative Agents (“ Agent ”), the other agents named therein and the Lenders from time to time parties thereto (“ Lenders ”). Terms used and not defined herein shall have the meanings given them in the Agreement.

Chesapeake Appalachia intends to execute a conveyance (the “ VPP Conveyance ”) of a volumetric production payment (the “ VPP ”) to be carved out of its working interests in approximately 4,200 specified presently producing wells (the “ VPP Wells ”) in Kentucky and West Virginia that are not included in the Collateral. The VPP Conveyance will not cover any other wells in which Chesapeake Appalachia owns an interest. In connection with the VPP, Chesapeake Appalachia intends to (i) enter into a Purchase and Sale Agreement (the “ VPP PSA ”), containing certain representations, warranties and covenants relating to the VPP and the VPP Wells and a restriction on further assignments of the VPP Wells, (ii) enter into a Gas Purchase Contract with the buyer of the VPP (the “ Gas Purchase Contract ”) to purchase the VPP buyer’s share of production at or near the wellhead at an index price (reduced for anticipated and estimated shrinkage and escalating transportation costs) and (iii) grant Liens on its retained interests in the VPP Wells and the production therefrom and its rights, titles and interests related thereto pursuant to one or more mortgages and deeds of trust (the “ VPP Mortgages ”), to secure performance of its ongoing covenants and obligations pursuant to the VPP Conveyance, the VPP PSA, and the Gas Purchase Contract. CEC intends to guaranty (the “ CEC Guaranty ”) Chesapeake Appalachia’s performance of these same covenants and obligations.

CEC and Borrowers have requested that Agent and Lenders constituting Majority Lenders consent to, and waive certain violations of the Agreement which would otherwise result from, the transactions described above.

LIMITED WAIVER AND CONSENT:

Subject to the conditions and limitations set forth below, Agent and Lenders hereby (i) consent to the conveyance of the VPP and the entering into and performance of the VPP Mortgages and the CEC Guaranty, and (ii) waive any violations of (A) Section 7.02 of the Agreement that would result from the Indebtedness of Chesapeake Appalachia in respect of the VPP and the Indebtedness of CEC in respect of the CEC Guaranty, (B) Section 7.03 of the Agreement that would result from the Liens under the VPP Mortgages, and (C) Section 7.12 of the Agreement that would result from any restrictions on Chesapeake Appalachia’s ability to assign or grant Liens on its retained interests in the VPP Wells and the assets subject to the VPP Mortgages.

[L IMITED W AIVER AND C ONSENT ]

For the avoidance of doubt with respect to the treatment of the VPP under the Credit Agreement, CEC, Borrowers and Lenders acknowledge and agree that, (i) Consolidated Indebtedness shall not include any Indebtedness in respect of the VPP and (ii) without duplication with respect to any other provision subtracting or excluding such income or gain in determining Consolidated EBITDA, any income or gain reflected in Consolidated Net Income for any period in respect of the VPP shall be subtracted from Consolidated Net Income for purposes of determining Consolidated EBITDA for such period.

Notwithstanding anything to the contrary under the Credit Agreement, CEC and Borrowers agree that no Group Member shall enter into or be subject to any Qualifying Production Call Obligation, and the exclusion of Qualifying Production Call Obligations from (i) the definition of “Indebtedness” in the Agreement and (ii) the restrictions on Liens provision under Section 7.3(o) of the Agreement, shall no longer be applicable.
