         could not be eliminated without unreasonable effort or expense;

         Form 10-K, Form 20-F, 11-K or Form N-SAR, or portion thereof, will be

PART III - NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 11-K, 10-Q, N-SAR,
or the transition report or portion thereof, could not be filed within the
prescribed time period.

Registrant is unable to complete its financial statements in time to file by the
March 31, 1999 filing date. The delay in completing the financial statements is
due to the company's inability to provide the company's auditors with the
necessary information on a timely basis to allow them to complete their audit
wihtin the required time period. It is expected that the audit will be completed
shortly and the Form 10-KSB will be filed by the end of the extension period.

    Securities Exchange Act of 1934 or Section 30 of the Investment Company Act

    earnings statements to be included in the subject report or portion thereof?
                                                        /x/ Yes  / / No

           ---------------------------------------------------------
                 (Name of Registrant as Specified in Charter)

has caused this notification to be signed on its behalf by the undersigned
hereunto duly authorized.

Date:  March 29, 1999                By Robert M. Carter
                                        Robert M. Carter
                                        President

        Tengasco, Inc. (the "Company") expects to have a loss for the year ended
December 31, 1998 in the amount of $3,204,394 as opposed to a loss for the year
ended Deceber 31, 1997 in the amount of $4,370,570.

        The Company produced revenues of $2,078,100 from its oil and gas wells
in Kansas and its Swan Creek location in Tennessee. Production costs from these
wells was $1,943,944. The decrease in loss for the year ended December 31, 1998
is attributable principally to two items -- the Company's interest expense
decreased $1,310,542 for the year; however, this was offset by an increase in
legal and accounting fees of $265,807.
