B. The Borrower has provided to the Administrative Agent and the Lenders the financial information for the four-quarter period ended June 30, 2016, which demonstrated that the Borrower had breached one or more of the financial ratios under Section 9.01 of the Credit Agreement for such period.

C. Yuma Energy, Inc. (“Yuma Energy”), certain merger subsidiaries of Yuma Energy and Davis Petroleum Acquisition Corp.

D. After the Borrower advised the Administrative Agent that the consummation of the Merger had been delayed until the third quarter 2016 and informed the Administrative Agent that the Borrower had failed to satisfy certain milestones established by the Ninth Amendment, the Borrower, the Administrative Agent and the Lenders entered into the Tenth Amendment to waive conditionally, among other breaches, the Borrower’s failure to comply with the covenants set forth in Section 6 of the Ninth Amendment and to establish updated milestones for the consummation of the Merger.

E.  Pursuant to the Tenth Amendment, failure of the S-4 to become effective on or before August 15, 2016 constitutes a Waiver and Amendment Extension Termination Date event.

F. The Borrower has informed the Administrative Agent and the Lenders that the S-4 did not become effective on or before August 15, 2015.

G. The Borrower has advised the Administrative Agent that consummation of the Merger, which was originally contemplated to be completed on or before September 30, 2016, likely has been delayed until the fourth quarter of 2016.

I. The Borrower has requested certain amendments, supplements, waivers and modifications to the Tenth Amendment and, subject to the conditions precedent set forth herein, the parties hereto have agreed to so amend, supplement, waive or otherwise modify the Tenth Amendment as set forth herein.

1. Same Terms. All terms used herein which are defined in the Credit Agreement shall have the same meanings when used herein, unless the context hereof otherwise requires or provides. In addition, (i) all references in the Loan Documents to the “Agreement” shall mean the Credit Agreement, as amended by this Waiver and Amendment, and (ii) all references in the Loan Documents to the “Loan Documents” shall mean the Loan Documents, as amended by this Waiver and Amendment, as the same shall hereafter be amended from time to time.

2. Amendments to Tenth Amendment. The Tenth Amendment is amended as follows:

B. Both the Borrower, on the one hand, and the Administrative Agent and the Lenders, on the other hand, agree that the reduction of the Borrowing Base pursuant to Section 3(A) shall continue to constitute the spring 2016 Scheduled Redetermination (and, in any event, shall not constitute an Interim Redetermination).

4. Limited Waiver.

A. The failure by the Borrower to comply with (i) the financial ratios set forth in Section 9.01(b) of the Credit Agreement for the fiscal quarter ended September 30, 2015, Section 9.01(a) and Section 9.01(b) of the Credit Agreement for the fiscal quarter ended December 31, 2015, Section 9.01(a) and Section 9.01(b) of the Credit Agreement for the fiscal quarter ended March 31, 2016, and Section 9.01(a), Section 9.01(b) and Section 9.01(c) for the fiscal quarter ended June 30, 2016, (ii) the covenants set forth in Section 6 of the Ninth Amendment, (iii) the requirement set forth in Section 8.01(a) of the Credit Agreement that the audited financial statements for the fiscal year ending December 31, 2015, not contain a “going concern” or like qualification, (iv) the covenants set forth in Section 8.16 of the Credit Agreement as a result of the Borrower’s failure to maintain Amegy Bank National Association as its principal depositary bank at all times prior to the effectiveness of the Tenth Amendment, (v) the requirement set forth in Section 3(A) of the Tenth Amendment, as in effect prior to this Waiver and Amendment, that the Borrower make a single lump sum payment in an amount equal to the lesser of the Borrowing Base Deficiency and $9,800,000 within two Business Days following the automatic reduction of the Borrowing Base and (vi) any Defaults or Events of Default arising as a result thereof, are each hereby conditionally waived (and any breach of any representation or warranty under the Credit Agreement or any other Loan Document as a result of the existence of such failures to comply is hereby similarly conditionally waived); provided that if the Borrower fails to make any mandatory payments as required by Section 3(A) of this Waiver and Amendment (if any), the foregoing waivers shall automatically expire at 5:00 p.m. eastern time on the Business Day any such mandatory payment becomes due but remains unpaid, and an Event of Default shall be deemed to have occurred as of September 30, 2015, and shall then continue and any and all remedies may be exercised unless or until each of the foregoing breaches has (i) been cured or (ii) further waived in accordance with the Credit Agreement. In the event that the mandatory payments required by Section 3(A) of this Waiver and Amendment (if any) are timely paid, the foregoing waivers shall become permanent.

B. The post-default rate of interest (which would otherwise apply as a result of the breaches described in the foregoing clause (A) of this Section 4 to the aggregate outstanding amount of all Loans from and after September 30, 2015) is hereby waived; provided that the waiver of the post-default rate of interest (1) shall be waived only so long as the provisions of Section 3(A) of this Waiver and Amendment are satisfied and the limited waivers described in clause (A) of this Section 4 have not terminated and (2) shall not apply to any other Default or Event of Default now existing or that may hereafter occur.
