WHEREAS, the Company has inadvertently failed to comply with (i) Section 10.05 of the Indenture requiring the delivery of the Reserve Report within 90 days after December 31, 2017, and (ii) Section 10.04(B) certifying compliance with the Minimum Mortgage Requirement concurrently with the delivery of the Reserve Report referenced in clause (i) above (the “Delivery Defaults”);

WHEREAS, during the period following the occurrence of the Mortgage Default, the Delivery Defaults, and the Certification Default, the Company declared and paid dividends on its Existing Preferred Stock in the months of April and May of 2018 unknowingly in breach of Section 3.11 of the Indenture, solely as the result of such other defaults, (the “Restricted Payment Default” and together with the Mortgage Default, the Delivery Defaults, the Certification Default, and any other Default or Event of Default as a result of any failure to comply with Section 3.06 of the Indenture in relation to the Mortgage Default, the Delivery Defaults, the Certification Default, or the Restricted Payment Default, collectively the “Existing Defaults”);

WHEREAS, the Company has announced, pursuant to a press release issued on June 11, 2018, that it has declared a dividend on its Existing Preferred Stock for the month of June 2018 to be payable to shareholders on July 2, 2018, and it has elected to suspend the declaration and payment of monthly cash dividends on its outstanding Existing Preferred Stock commencing July 2018 to maintain liquidity to support its capital investment program;

WHEREAS, Section 8.02 of the Indenture provides that, with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, the Company, the Guarantor, the Trustee and the Collateral Trustee may enter into an indenture supplemental to the Indenture for the purpose of amending or supplementing the Indenture or the Notes (subject to certain exceptions);

WHEREAS, the Company desires and has requested the Trustee and the Collateral Trustee to join with it and the Guarantor in entering into this Supplemental Indenture for the purpose of amending the Indenture and the Notes, as permitted by Section 8.02 of the Indenture, and to, subject to the satisfaction of the conditions set forth in Section 5 below, waive the Existing Defaults; and
