The facilities provided under the Amended and Restated Credit Agreement are to be used to refinance Borrowers prior outstanding revolving loan facility with Bank, dated July 3, 2008, and for working capital and general corporate purposes. At our option, loans under the facility will bear stated interest based on the Base Rate plus Base Rate Margin, or Floating Rate plus Floating Rate Margin (as those terms are defined in the Credit Agreement). The Base Rate will be, for any day, a fluctuating rate per annum equal to the higher of (a) the Federal Funds Rate plus 0.50% and (b) the Bank's prime rate. The Floating Rate shall mean, at Borrower's option, a per annum interest rate equal to (i) the Eurodollar Rate plus Eurodollar Margin, or (ii) the Base Rate plus Base Rate Margin (as those terms are defined in the Amended and Restated Credit Agreement). Eurodollar borrowings may be for one, two, three, or six months, as selected by the Borrowers. The margins for all loans are based on a pricing grid ranging from 0.00% to 0.75% for the Base Rate Margin and 2.25% to 3.00% for the Floating Rate Margin based on the Company's Borrowing Base Utilization Percentage (as defined in the Amended and Restated Credit Agreement). We entered into a First Amendment to Amended and Restated Credit Agreement and Second Amended and Restated Promissory Note in the amount of $50,000,000 with the Texas Capital Bank, which closed on December 15, 2011. The Amendment reflects the addition of Rantoul Partners, as an additional Borrower and adds as additional security for the loans the assets held by Rantoul Partners. We entered into a Second Amendment and Restated Credit Agreement and Second Amended and Restated Promissory Note in the amount of $50,000,000 with the Texas Capital Bank, which closed on August 31, 2012. The Amendment reflects the following changes: i) the reduction of the minimum interest rate to 3.75%, ii) an increase in the borrowing base to $7.0 million, iii) the addition of a provision resulting in an event of default if Robert G. Watson ceases to be the chief executive officer of any Borrower for any reason and a successor reasonably acceptable to Administrative Agent is not appointed within one hundred twenty (120) days thereafter, and iv) the addition of new leases to the collateral pool. We entered into a Third Amendment to Amended and Restated Credit Agreement and Second and Restated Promissory Note in the amount of $50,000,000 with The Texas Capital Bank which closed on November 5, 2012. The Amendment reflects the following changes: i) an increase in the borrowing base to $12.150 million, ii) the addition of a provision permitting the repurchase of up to 2,000,000 of common stock on or before December 31, 2013, subject to certain liquidity requirements, iii) the amendment of certain financial covenant definitions for the purposes of clarity, and iv) the provision of a limited waiver for the failure to comply with the Interest Coverage Ratio for the period ending December 31, 2011. Our Current borrowing base is $12.150 million, of which we had borrowed $8.5 million as of December 31, 2012. We intend to conduct an additional borrowing base review around the end of the first quarter of 2013 and we expect increases in production and the maturity of existing production to result in an additional borrowing base increase prior to such additional borrowing base review. For the year ended December 31, 2012 the interest rate was 3.75%. This facility expires on October 3, 2015. We financed the purchase of vehicles through a bank. The notes are for four years and the weighted average interest is 7.2% per annum. Vehicles collateralize these notes. At December 31, 2011 a $7,000 balance remained on the note. All amounts due on these notes were paid in 2012.

At our option, loans under the facility will bear stated interest based on the Base Rate plus Base Rate Margin, or Floating Rate plus Floating Rate Margin (as those terms are defined in the Credit Agreement). The Base Rate will be, for any day, a fluctuating rate per annum equal to the higher of (a) the Federal Funds Rate plus 0.50% and (b) the Bank's prime rate.

The Floating Rate shall mean, at Borrower's option, a per annum interest rate equal to (i) the Eurodollar Rate plus Eurodollar Margin, or (ii) the Base Rate plus Base Rate Margin (as those terms are defined in the Amended and Restated Credit Agreement). Eurodollar borrowings may be for one, two, three, or six months, as selected by the Borrowers. The margins for all loans are based on a pricing grid ranging from 0.00% to 0.75% for the Base Rate Margin and 2.25% to 3.00% for the Floating Rate Margin based on the Company's Borrowing Base Utilization Percentage (as defined in the Amended and Restated Credit Agreement).

We entered into a First Amendment to Amended and Restated Credit Agreement and Second Amended and Restated Promissory Note in the amount of $50,000,000 with the Texas Capital Bank, which closed on December 15, 2011. The Amendment reflects the addition of Rantoul Partners, as an additional Borrower and adds as additional security for the loans the assets held by Rantoul Partners.

The Amendment reflects the following changes: i) the reduction of the minimum interest rate to 3.75%, ii) an increase in the borrowing base to $7.0 million, iii) the addition of a provision resulting in an event of default if Robert G. Watson ceases to be the chief executive officer of any Borrower for any reason and a successor reasonably acceptable to Administrative Agent is not appointed within one hundred twenty (120) days thereafter, and iv) the addition of new leases to the collateral pool.
