NOTE 4 – LINE OF CREDIT

The Company has a credit agreement with Whitney Bank and JPMorgan Chase Bank, N.A. (as amended, the “Credit Agreement”) that provides the Company with an $80 million revolving credit facility (the “Credit Facility”). The Credit Agreement also allows the Company to use up to the full amount of the available borrowing base for letters of credit and matures on December 31, 2014. We intend to renew the Credit Facility prior to its expiration.

The Credit Facility is secured by substantially all of our assets other than real property located in the state of Louisiana. Amounts borrowed under the Credit Facility bear interest, at our option, at either the prime lending rate established by JPMorgan Chase Bank, N.A. or LIBOR plus 1.5 percent. We pay a fee on a quarterly basis of one-fourth of one percent per annum on the weighted-average unused portion of the Credit Facility.

At June 30, 2014, no amounts were outstanding under the Credit Facility, and we had outstanding letters of credit totaling $47.8 million, reducing the unused portion of our revolving credit facility to $32.2 million. We are required to maintain certain financial covenants, including a minimum current ratio of 1.25 to 1, a net worth minimum requirement of $250.3 million, debt to net worth ratio of 0.5 to 1, and earnings before interest, taxes, depreciation and amortization (EBITDA) to interest expense ratio of 4.0 to 1. As of June 30, 2014, we were in compliance with all covenants.
