            Item 1.01- Entry into a Material Definitive Agreement
            Item 1.02-Termination of a Material Definitive Agreement

On October 5, Tengasco, Inc. signed and accepted a subscription agreement whereby Hoactzin Partners, L.P. (“Hoactzin”) subscribed for a 94.275% working interest in a twelve well drilling program to be undertaken by the Company on its properties in Kansas. The Company retains the balance of the 5.725% working interest in the drilling program in Kansas not owned by Hoactzin. In exchange for its interest in the drilling program, Hoactzin surrendered to the Company two promissory notes made by the Company to Dolphin Offshore Partners, L.P. (“Dolphin”) in the aggregate principal amount of $2.514 million which had been assigned to Hoactzin. Hoactzin also will release all liens securing these notes. These notes had been issued in connection with loans made to the Company by Dolphin to fund the Company’s offer to holders of the Company’s Series A, B and C Preferred Stock to exchange their Preferred Stock for a discounted cash payment of the face value of their Preferred Stock together with any accrued unpaid dividends and interest thereon. Upon Hoactzin’s receipt of proceeds form its working interest in the drilling program in the amount of $3,016,800, Hoactzin will then pay to the Company a management fee equal to 85% of its net revenues attributable to its working interest in the drilling program for the remaining life of all the program wells. The Company has an option expiring March 31, 2006 to repurchase the obligations to drill the final six wells of the twelve well program for $222,222 per well, plus interest on that amount at 6% per annum until the date of any repurchase, plus a 1/16 overriding royalty to Hoactzin in the six program wells and the next six drilled by the Company in Kansas. Payout and management fee calculations would also be adjusted to reflect any reduction to a six well program.

Peter E. Salas, the Chairman of the Board of Directors of the Company, is the controlling person of Hoactzin. He is also the sole shareholder and controlling person of Dolphin Management, Inc., the general partner of Dolphin which is the Company’s largest shareholder.
