Re: Engagement of Southcoast Capital L.L.C.
    ---------------------------------------

Gentlemen:

Representatives of Southcoast Capital L.L.C. ("SCC") and Tengasco, Inc. (the
"Company"), have discussed on a confidential basis, the Company's short-term and
long-term financial and business objectives, goals and needs and the financial
advisory and investment banking services (collectively, "Investment Banking
Services") which SCC can provide to the Company. More specifically, the Company
has requested that SCC assist the Company with a proposed private placement of
convertible preferred stock, although the placement may ultimately consist of
convertible preferred stock, debentures, common stock, warrants or a combination
thereof, all of such securities either individually or collectively being
referred to hereinafter as the "Securities."

 Accordingly, the purpose of this letter (this "Agreement") is to confirm and
 set forth the following terms and conditions under which SCC will render
 Investment Banking Services to the Company based on its understanding of the
 Company's current intentions:

 1.  Engagement. The Company will engage SCC as its exclusive financial advisor
     to the Company for the purpose of providing Investment Banking Services
     with respect to a private placement of Securities as described herein. In
     addition, during the term of its engagement, SCC will provide such other
     Investment Banking Services as the officers of the Company may reasonably
     request. For purposes hereof, the term "Company" shall include any
     subsidiary or affiliate of the Company.

2.   Private Placement. The Securities of the Company will be privately offered
     and sold in reliance upon certain exemptions from registration under the
     Securities Act

     of 1933 (the "Securities Act") including Regulation D under the Securities
     Act on a "best efforts" basis. The Securities will be sold to persons who
     are "accredited investors" (as defined in Rule 506 of Regulation D under
     the Securities Act) or persons who are otherwise suitable for such an
     investment. The Company, with SCC's assistance, will prepare a disclosure
     document to be used in connection with the offer and sale of the
     Securities. The disclosure will conform to the Securities Act and the rules
     and regulations thereunder, including Regulation D, and applicable state
     securities laws. The disclosure document shall be satisfactory in all
     material respects to our legal counsel.

3.   Offering Price. The offering price for the Securities will be determined by
     agreement among the Company, SCC and the investor(s). The aggregate gross
     proceeds from the sale of the Securities will be at least $3,000,000,
     unless otherwise agreed by SCC and the Company.

4.   Compensation. The Company agrees to pay SCC an initial financial advisory
     fee of $10,000, payable upon the signing of this Agreement. Such initial
     financial advisory fee shall be creditable against any other fees earned by
     SCC hereunder. As a placement fee, SCC shall be entitled to an amount of
     cash equal to eight percent (8%) of the total gross proceeds resulting from
     the placement of the Securities. In addition, the Company shall issue to
     SCC a warrant (the "Warrant") to purchase a number of shares of the
     Company's Common Stock equal to ten percent (10%) of the total number of
     shares of any Common Stock placed hereunder and/or the underlying Common
     Stock into which any of the Securities are convertible. The Warrant will be
     for a term of five (5) years and the purchase price for shares of Common
     Stock subject to the Warrant shall equal for Common Stock placed hereunder,
     the price per share at which it is placed and, for convertible securities
     placed hereunder, the conversion price per share of Common Stock. If the
     Common Stock trades at a 200% premium to the offering or convertible price
     for 20 consecutive trading days at any time during the life of the Warrant,
     the Company may exercise its call provision to redeem the Warrants for
     $0.05 per underlying share of Common Stock. The Company will register the
     Common Stock underlying the Warrant when it next files a registration
     statement with the Securities and Exchange Commission and keep such
     registration statement current and active for such time as the Warrant is
     exercisable. The Company also agrees to reimburse SCC for its out of pocket
     expenses, including the fees and expenses of SCC's legal counsel, provided
     that, without the prior agreement of the Company, the aggregate of such
     expenses shall not exceed $15,000.

5.   Introduction to Financing Sources. In connection with providing its
     services hereunder, SCC will contact and may introduce the Company to
     various potential financing sources, (each an "Identified Party"). Before
     or within thirty (30) days after introduction of an Identified Party, SCC
     will send to the Company a letter confirming the identification of such
     party to the Company at which time such Identified Party shall become
     subject to, the terms of the Agreement, and SCC shall be entitled to a
     placement fee calculated in accordance with paragraph 4 above with

                                                                               2
<PAGE>

     respect to any financing transaction entered into within one (1) year of
     the termination of this Agreement.

 6.  Terms of Securities. The Securities will have such rights and privileges
     concerning, among other things, conversion and redemption rights, interest
     rates or dividend rates and voting rights as determined by agreement among
     the Company, SCC and the investor(s) who subscribe to purchase the
     Securities. The Company will register the common stock (the "Common Stock")
     of the Company into which the Securities are convertible ("Underlying
     Common Stock") and keep such registration statement current and active for
     such time as the Securities are convertible into the underlying Common
     Stock.

 7.  Legal Counsel. The Company's legal counsel will make all required filings
     with the various states in which the Securities are offered. In this
     regard, the Company will supply SCC's legal counsel with such number of
     complete copies of the disclosure document, and all exhibits, as may be
     required to be filed. The Company will be responsible for filing a Form D
     with the U.S. Securities and Exchange Commission and will provide SCC with
     evidence of such filing.

 8.  Cost and Expenses. The Company will be responsible for and bear all
     expenses incurred in connection with the proposed offering, including, but
     not limited to, the cost of preparation of the disclosure document and any
     supplements or amendments thereto, and all filing fees and costs connected
     with the "blue sky" laws of those states in which the offering is to be
     made.

9.   Due Diligence Investigation. From and after the date of execution and
     delivery of this Letter, the Company will continue to afford SCC and its
     agents, attorneys and accountants reasonable access to the business records
     and properties of the Company and will furnish to SCC all information
     concerning its business for the purpose of enabling SCC to make such
     financial, accounting, legal or other investigations deemed necessary or
     appropriate by SCC.

10.  Capitalization. The Company will have authorized sufficient amounts of the
     Securities for the offering contemplated herein, including the conversion
     of the Securities and the exercise of the Warrant. The Company agrees to
     undertake such corporate actions as may be necessary and appropriate to
     authorize and consummate the proposed offering, and take such other action
     or actions as SCC may reasonable request.

 11.  Dissemination of Information. The Company will consult with SCC prior to
      any public dissemination of any information or documentation regarding the
      Company, its affiliates, or its business during the period of the offering
      or any term of the offering and will provide SCC with all such material
      prior to any dissemination during the term of the offering.

                                                                               3

12.  General Conditions. SCC's intentions as expressed herein are subject to the
     following further general conditions:

             12.1 There shall have been no materially adverse change in the
                  business or conditions (financial or otherwise) of the Company
                  or any materially adverse change in the securities market or
                  any other event or occurrence which, in the sole judgement of
                  SCC may adversely affect the ability of SCC to proceed with
                  the offering. SCC shall be satisfied with the Company's
                  progress as well as its outlook on the future.

     the Company or SCC and without liability or continuing obligation by either
     party to the other (other than for any fees or other compensation earned
     and expenses incurred by SCC up to the date of any such termination).

14.  Disavowal of Agency. In no event shall SCC or any of its principals or
     employees be deemed to be an agent or employee of the Company and shall not

 15. Confidentiality. Except as otherwise agreed to by the Company or as is
     required by law or is necessary to complete its engagement hereunder, SCC
     will keep confidential all information which is supplied by the Company and
     which has not previously entered the public domain, and will not use any
     such information for its own benefit except in connection with the matters
     undertaken pursuant to the terms of this engagement. At the termination of
     this agreement, upon the request of the Company, SCC shall return all

     AGAINST AND FROM ANY AND ALL LOSSES, CLAIMS, DAMAGES, OR LIABILITIES, JOINT
     OR SEVERAL, TO WHICH SCC MAY BECOME SUBJECT IN CONNECTION WITH THE
     TRANSACTIONS REFERRED TO HEREIN UNDER ANY OF THE FEDERAL SECURITIES LAWS,
     UNDER ANY OTHER STATUTE, AT COMMON LAW OR OTHERWISE, AND TO REIMBURSE SCC

       At the end of the initial ten year term of this agreement, the District
shall have the option to extend this agreement for an additional ten-year term.
If the District exercises its option to extend this agreement for an additional
ten-year term, the District shall own all facilities installed by TPC at the end
of such additional term and Sections 5 and 5.1 hereof shall not apply. TPC shall
transfer ownership of such facilities to the District by appropriate instruments
at that time and the District shall expressly assume all obligations under the
gas purchase contracts whereby TPC purchases or is to purchase gas for supply to
the District. If the District does not exercise its option to extend this
agreement for a second ten-year term, then the District shall be obligated to

       SECTION 4. All work undertaken or performed, all service rendered, and

provisions of this

                                       4

<PAGE>

franchise shall be the standard required by law, by the orders of the Tennessee
Regulatory Authority of the State of Tennessee, and by any other body or
governmental authority having jurisdiction in the premises. All facilities or
equipment of the Grantee to be laid, constructed, erected, installed or
repaired, in, upon, along, across, under or over the streets of the District, or
removed from the streets of the District pursuant to the provisions of this
franchise, shall be laid, constructed, erected, installed, repaired or removed
in accordance with the rules and regulations of the District now or hereafter
adopted or prescribed with the agreement of TPC which agreement shall not be
unreasonably withheld, except where in conflict with the State law, orders of
the Tennessee Regulatory Authority, or other governmental authority having
jurisdiction in the premises.

       SECTION 5. The ownership of the Facilities shall remain in TPC while this
agreement is in effect. The Facilities may be sold by TPC to the District at the
following times and under the following terms: (1) at the sole option of the
District at the end of the initial ten-year term hereof only; (2) by agreement
of TPC at any time during and prior to the end of the initial term; or (3) if

end of the second ten-year term. At any time the Facilities are purchased by the
District, the District shall be entitled to purchase and TPC shall be obligated
to sell the Facilities of TPC installed pursuant to this Agreement at the fair
market value of the Facilities. The District shall, at the time of any purchase,
assume all of TPC's gas contracts for gas to supply the District. The fair
market value of the Facilities shall include an element for replacement cost and
going concern value as well as net book value and shall be determined in the
exercise of sole reasonable discretion by TPC. Should the District not agree

                                       5

<PAGE>

with the fair market value so determined, at the end of the initial term only,
the fair market value at that time only shall be determined by a single
arbitrator in binding arbitration under the Commercial Arbitration Rules of the
American Arbitration Association as then in force, or by any other means of
binding arbitration by one or more arbitrators upon which the parties to this
agreement may specifically agree in writing. In all other instances when fair
market value is to be determined, the fair market value is in the sole
reasonable discretion of TPC.

       SECTION 5.1 If the termination of this agreement occurs at the expiration
of the ten year initial term, TPC agrees that the net book value of the
Facilities shall be deemed to have been paid to TPC in the rates charged and
collected, to the extent and only to the extent that such rates charged and
collected have been in excess of TPC's cost of service (gas costs, operating
costs, taxes, interest expense on monies borrowed by TPC to install the
facilities, and return on investment). TPC expressly agrees that any excess of
the fair market value as may be determined by the provisions of Section 5 which
may exceed the net book value deemed paid pursuant to the previous sentence, if
any, maybe paid by promissory note or other obligation of the District as the
District may elect which shall not cause the District to attempt to issue bonds
in any amount which may not be supported by law. Any promissory note or other
obligation for any portion of the fair market value shall be payable for a
period not exceeding five (5) years and at an interest rate of not less than
prime (Wall Street Journal) plus one percent as published most recently prior to
the date of such note, payable monthly, unless TPC agrees to other terms. In
such instance where a promissory note may be given, TPC shall transfer ownership
of the facilities in place to the District, and the District shall secure
payment of any such promissory note or other agreed obligation by a security
interest

                                        6

<PAGE>

in the facilities so transferred.

       SECTION 5.2 All billing and administrative functions in connection with
services hereunder shall be performed by TPC or its designee as agent of the
District. The District shall not be charged any fee for such functions. The
District shall have access at all reasonable times to the books and records of
TPC or its designee insofar as all records of TPC or its designee under this
agreement are concerned in order to verify the accuracy of any computations
required hereunder.

       SECTION 6. The Grantee of this franchise shall not lay, construct, erect
or install its facilities or equipment, in, upon, along, across, under or over
the streets of the District until and unless the proposed location of such
facilities or equipment shall have been approved by the District, or such other
officer of the District as the District may direct, and which approval shall not
be unreasonably withheld.

       SECTION 7. (a) Before making any opening or excavation in any street, or
before distributing the earth beneath the surface of any street, regardless of
whether the surface thereof is damaged or removed or not, except in case of
emergency, the Grantee shall file with the District a drawing or plan showing
the proposed location, elevation above or below the established grade of the
center line of the street, and the character of its facilities or equipment to
be laid, constructed, erected, installed, used, repaired in, upon, along,
across, under or over the streets of the District, or removed from the streets
of the District for all its facilities except service connections which shall be
furnished within thirty (30) days after installation.

       (b) If the proposed location of any facilities or equipment to be

                                       7
<PAGE>

laid, constructed, erected, used, repaired or replaced by the Grantee in, upon,
along, across, under or over the streets of the District, or removed from the
streets of the District by the Grantee does not interfere (1) with the use of
the streets for the purpose of travel, (2) with any proposed or contemplated use
of the streets by the District either above or below the surface of the street,
for which plans have been prepared, or for which plans are in the course of
preparation, which plans have been authorized by the District, or the
legislative body of the District, (3) with personal property lawfully in, upon,
along, across, under or over the streets, and otherwise complies with this
franchise, and any agreement, rule or regulation of the District in force and
effect at the time of such application, the District shall approve said
application and a permit shall be issued therefor by the proper District
authority.

       SECTION 8. The work of laying, constructing, erecting, installing, using,
operating, maintaining, repairing or replacing in, upon, along, across, under or
over the streets of the District, or removing from the streets of the District,
any facilities or equipment of the Grantee, shall be done, performed, or
conducted with the least practicable hindrance of the use of the streets for the
purpose of travel or any other public purpose.

       SECTION 9. (a) When any opening or excavation is made, or work done, in,
upon, along, across, under or over the streets, for any purpose whatsoever by
the Grantee, in connection with the exercise of any right or privilege granted
by this franchise, any portion of said streets affected or damaged thereby shall
be restored as promptly as practicable by the Grantee to as useful, safe,
durable and good condition as existed prior to the making of such opening or
such excavation or the doing of such work.

       (b) By the acceptance of this franchise, the Grantee agrees that

                                       8

<PAGE>

after the work of restoring such portion of said street has been completed as
provided in the paragraph above, it will keep such portion of said street so
restored, in as useful, safe, durable and good condition as existed prior to the
making of such opening or excavation or the doing of such work, ordinary wear,
tear and use excepted, for a period of twelve (12) months, if the District
determines that such portion of such street was affected or damaged by such
opening or excavation made, or such work done in, upon, along, across or over
the said street by the Grantee, provided such obligation on the part of the
Grantee shall terminate twelve (12) months after the date of any such original
restoration.

       SECTION 10. After any work has been commenced by the Grantee in, upon,
along, across, under or over the streets of the District, pursuant to the
provisions of this franchise, the same shall be prosecuted in good faith and
with due diligence until completed.

       SECTION 11. (a) Any pipe, pipe line, tube, main, service, conduit, duct
or other structure laid, constructed, erected, or installed pursuant to the
provisions of this franchise, or any tunnel or bore dug or made in the streets
of the District in connection with the laying, constructions, erection or
installation of the property above mentioned in this section, shall be not less
than thirty (30) inches below the surface of the street or the ground, as the
case may be, when such installation is three (3) inches or over in diameter and

three (3) inches in diameter and measured in each instance from said established
grade of the nearest point to said property, tunnel or bore as the case may be.

                   (b) Where, however, such depths are impracticable due to

<PAGE>

duly authorized officer of the District as to the suitable depth or location of
said property, tunnel or bore and the same shall be placed in conformity with
such approved location or depth, and in a manner reasonably satisfactory to the
District or other authorized officer of the District.

                   (c) All manholes, vaults, traps, catch basins or other
structures, shall be so capped and covered as to be flush with the surface of
the street, and shall not interfere in any way with the use of the streets for
the purpose of travel.

                   (d) The Grantee shall not lay, construct, erect, or install
in the streets of the District any vent pipe from any vault, manhole or other
structure of the Grantee except in the manner and at the location or locations
prescribed or approved by the District and only in accordance with sound
engineering practices.

       SECTION 12. Upon abandonment of any of the facilities or equipment of the
Grantee located above or below the surface of the streets, the Grantee shall
notify the District in writing of such abandonment within twenty (20) days
thereafter; and if such abandoned facilities or equipment will then unreasonably
interfere with the then contemplated use of said street by the District, the
District shall give written notice thereof to the Grantee within twenty (20)
days after receipt of said notice of abandonment and the Grantee shall commence
the removal of same within twenty (20) days after receipt of said notice from
the District and prosecute said work to completion with reasonable diligence and
at its own cost and expense.

       SECTION 13. If during the term of this franchise, the District shall
change the grade, width or location of any street, or improve any street in any
manner, including laying of any sewer, storm drain, conduit, water or other
pipe, or construct any pedestrian tunnel

                                       10

<PAGE>

or other improvement, and, in the opinion of the District such work shall render
necessary any change in the position or location of any facilities or equipment
of the Grantee in the streets including the support thereof while such work is
being done or performed, the Grantee, at its own cost and expense, within twenty
(20) days after written notice from the District so to do, shall begin the work
of doing any and all things to effect such change in position or location in
conformity with such written instructions.

       SECTION 14. If the Grantee is dissatisfied with any determination of the
District permitted by the foregoing Sections hereof, it may petition the
District to review the same within ten (10) days after such determination, but
such remedy shall be cumulative and not exclusive.

       SECTION 15. The District shall not impose any rental, license fee, charge
or tax upon the Grantee for the rights hereby granted, or the exercise thereof,
that is not uniformly imposed and collected by the District upon the same basis
on all other publicly or privately owned competing public service companies.

       SECTION 16. TPC shall maintain a policy of general liability insurance in
the amount of ten million dollars, including umbrella coverage, at all times
this agreement is in effect. The District and the directors of the District
shall be named as additional insureds on such policy.

       TPC agrees to provide at its initial cost and expense, for the benefit of
the District a performance bond in the amount of $200,000 guaranteeing its
performance of obligations under this Franchise Agreement, and payable to the
District in the event and to the extent judgment is rendered in a court of
competent jurisdiction that the District has incurred and is entitled to receive
damages as a result of any breach of this agreement by TPC, and to

                                       11

<PAGE>

maintain that bond in force during the term of this agreement. The District
agrees that because the bond is required and maintained for benefit of the
District and its customers, the annual cost of acquiring and maintaining this
bond shall be either deducted in equal monthly installments from the five
percent of gross proceeds to which the District is entitled under this agreement
until repaid in full to TPC, or collected as an additional charge from consumers
purchasing gas from the District until paid in full and thereafter reimbursed to
TPC, as TPC and the District may agree.

       SECTION 17. The Grantee shall use reasonable care and precaution in
laying, constructing, erecting, installing, using, operating, repairing, or
maintaining its facilities and equipment located in, upon, along, across, under
or over the streets of the District to avoid damage or injury to persons or
property; and shall indemnify, defend (including payments of attorneys' fees,
court costs, etc.) and save harmless the District from any and all liability by
reason of damage or injury to persons or property on account of the Grantee's
negligence in such work, provided the District shall have notified the Grantee
in writing of any claims against the District on account thereof in ample time
to enable the Grantee to defend the same.

       The Grantee shall furnish the District annually certificate or
certificates evidencing its insurance coverage of the foregoing risks in good
and solvent insurance companies authorized to do business in the State of
Tennessee.

       SECTION 18. The Grantee shall run a service pipe to the gas meter serving
all buildings on the lines of its mains, provided a written application is made
by the consumer agreeing to use gas, and provided that the point wherever the
service pipe to the gas meter

                                       12

<PAGE>

serving the building shall not be more than sixty (60) feet inside the property
line. The Grantee shall also maintain, repair and keep in good condition all of
the service pipes, and keep the same free from all obstruction up to the point
of entrance to the building free of charge to the consumer. The Grantee shall
not be obligated to extend its mains except upon written application therefor by
the prospective consumer upon Grantee's customary forms, agreeing to accept and
pay for service in accordance with Grantee's rules and regulations and tariffs
on file. Grantee shall not in any event be required to install or extend any
mains if in Grantee's reasonable judgment it would be uneconomical to do so.
Nothing contained in this Section 18 shall be construed as limiting or impairing
the authority of the Tennessee Regulatory Authority of the State of Tennessee.

       SECTION 19. All gas transmitted, distributed, supplied and sold by the
Grantee under this agreement, shall be furnished and paid for in accordance
with, and subject to, all of the provisions of the applicable rates, and
schedule of charges and such change or changes as may be made in the terms and
conditions of service from time to time.

       The District shall have jurisdiction to prescribe and fix rates, charges,
terms and conditions governing the furnishing of said gas service, which shall
be sufficient to yield the Grantee a reasonable return upon the fair value of
its Facilities, including Facilities paid for with either borrowed or invested
capital, used and useful in rendering said service. Because the number of
customers, the purchased volumes, and investment costs are uncertain, the
District agrees that to assure a reasonable return to TPC, the rates prescribed
by the District shall not be less than an average of rates for comparable
service provided by at least three districts adjacent to or near the District to
be selected by TPC, unless TPC agrees in its sole

                                       13

<PAGE>

discretion to a lesser rate.

       SECTION 20. No transfer, assignment or lease, or attempted transfer,
assignment or lease, of this franchise, or of any right, privilege or interest
therein, to any person, firm or corporation shall have any force, effect or
validity unless and until: .

       (1) The Grantee shall have duly executed a good and sufficient instrument
making such transfer, assignment or lease, and a duplicate original thereof
shall have been filed in the office of the District.

       (2) The transferee, assignee, or lessee shall have duly executed a good
and sufficient instrument accepting such transfer, assignment or lease, and
assuming all the obligations of the Grantee (including without limitation all
gas contracts entered into by TPC for purchase of gas to be supplied to the
District) under this franchise, and an original thereof shall have been filed in
the office of the District.

       Nothing contained in this Section 20 shall be construed to apply or
effect in any manner any mortgage, deed of trust, indenture or other instrument
given by the Grantee (or by any person, firm or corporation under a transfer,
assignment or lease made in full accordance with the provisions of this Section)
to secure an issue of bonds or other evidence of indebtedness. However, the
terms of clauses (1) and (2) shall apply to the surviving corporation pursuant
to any statutory merger.

       SECTION 21. Any written notice herein required to be given by the
District, or any of its officers or agents, to the Grantee, shall be deemed to
have been duly served if delivered in person to any officer of the Grantee or to
its local agent or manager, or if sent by certified mail to the postal address
of the Grantee, or by facsimile transmission.

                                       14

<PAGE>

       SECTION 22. The use of the singular number herein shall include the
plural, and the use of the plural number shall include the singular.

       SECTION 23. This agreement shall become effective and all its terms,
provisions and conditions binding upon both the District and the Grantee fifteen
(15) days after its execution by the District, provided the Board of Directors
of Grantee approves the agreement and Grantee shall within said fifteen (15)
days endorse on the original document its acceptance of this agreement in words
and figures following: "Tengasco Pipeline Corporation hereby accepts this
Agreement this 25th day of January 2000."
