On March 28, 2016, the Company’s senior credit facility with Prosperity Bank after Prosperity Bank’s most recent review of the Company’s currently owned producing properties was amended to decrease the Company’s borrowing base from $7.8 million to approximately $3.2 million, extend the term of the facility to January 30, 2018, and delete the Leverage Ratio covenant. For the quarter ended December 31, 2015, the Company was in default on compliance with the Leverage Ratio covenant. In addition, the amendment also added a Debt to Tangible Net Worth covenant, waived the default on the Interest Coverage ratio for the quarter ended December 31, 2015, waived the anticipated default for the quarter ended March 31, 2016, and waived compliance with the Interest Coverage ratio for all applicable periods through the maturity date. Although the Company was in default of the Leverage and Interest Coverage ratios for the quarter ended December 31, 2015, the Company was in compliance at March 28, 2016 as a result of the amendment and waivers. As of March 31, 2016, the Company was in compliance with all covenants. The borrowing base remains subject to the existing periodic redetermination provisions in the credit facility. The interest rate remained prime plus 0.50% per annum. This rate was 4.00% at the date of the amendment. The maximum line of credit of the Company under the Prosperity Bank credit facility remained $40 million. The next borrowing base review will take place in August 2016.
