Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant

        On December 17, 2007, Tengasco, Inc. (the “Company”) executed an assignment of a revolving senior credit facility between the Company and Citibank Texas, N.A.to Sovereign Bank (“Sovereign”) of Dallas, Texas as requested by the Company.

        Under the facility as assigned to Sovereign, loans and letters of credit will be available to the Company on a revolving basis in an amount outstanding not to exceed the lesser of $20,000,000 or the borrowing base in effect from time to time. The Company’s initial borrowing base with Sovereign was set at $7.0 million, an increase from the borrowing base of $3.3 million in effect with Citibank prior to the assignment.

        The initial borrowing on December 17, 2007 by the Company under the new facility with Sovereign was approximately $4.2 million to bear interest at a floating rate equal to prime as published in the Wall Street Journal plus 0.25%, resulting in a current rate of interest of approximately 7.5%. Interest only is payable during the term of the loan and the principal balance of the loan is due December 31, 2010. The facility as assigned is secured by substantially all of the Company’s producing and non-producing oil and gas properties and pipeline and the Company’s methane project assets.

        The Company used a portion of the $4.2 million borrowed from Sovereign to pay off the $3.3 million it previously borrowed from Citibank. The remaining $900,000 borrowed from Sovereign was used to pay bank fees and attorney fees relating to the assignment in the amount of approximately $75,000 and the balance of approximately $825,000 was used to pay a portion of the purchase price for equipment to be utilized in the methane extraction facility currently under construction in Carter Valley, Tennessee by the Company’s wholly-owned subsidiary, Manufactured Methane Corporation (“MMC”). It is anticipated that the Carter Valley methane project will cost approximately $4.1 million, which includes treatment equipment, pipeline construction, compression and controls. To date, MMC has paid approximately $2.6 million or 63% of the total expected methane project costs of which approximately $1.8 million has been paid from the Company’s operating revenues. The Company anticipates that most of the remaining balance of the methane project costs will also be paid from the Company’s cash flow.

        The information in this Form 8-K (including Exhibit 99.1) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, except as expressly set forth by specific reference in such a filing.
