....................................... ..... ............... 751 FORWARD LOOKING STATEMEN T S

The information contained in this Report, in certain instances, includes forward

- looking statements within the meaning of applicable securities laws. Forward

- looking statements include statements regarding the Company’s “expectations,” “anticipations,” “intentions,” “beliefs,” or

“st rategies” or any similar word or phrase regarding the future. Forward

- looking statements also includ e statements regarding revenue margins, expenses, and earnings analysis for 201 2 and thereafter ; oil and gas prices; exploration activities; development expenditures; costs of regulatory compliance; environmental matters; technological developments; future products or product development; the Company’s products and distribution development strategies; potential acquisit ions or strategic alliances; liquidity and anticipated cash needs and availability; prospects for success of capital raising activities; prospects or the market for or price of the Company’s common stock; and control of the Company. All
forward

- looking st atements are based on information available to the Company as of the date hereof, and the Company assumes no obligation to update any such forward

- looking statement. The Company’s actual results could differ materially from the forward

- looking statements. Among the factors that could cause results to differ materially are the factors discussed in “Risk Factors” below in Item 1A of this Report.

Projecting the effects of commodity prices, which in past year s have been extremely volatile, on production and t iming of development expenditures includes many factors beyond the Company’s control. The future estimates of net cash flows from the Company’s proved reserves and their present value are based upon various assumptions about future production levels, pric es, and costs that may prove to be incorrect over time. Any significant variance from assumptions could result in the actual future net cash flows being materially different from the estimates.

GLOSSARY OF OIL AND GAS TERMS

The following are abbreviations and definitions of certain terms commonly used in the oil and gas industry and this document:

Bbl. One stock tank barrel, or 42 U.S. gallons liquid volume, used in reference to oil or other liquid hydrocarbons.

Bcf. One billion cubic feet of gas.

BOE . One stock tank barrel equivalent of oil, calculated by converting gas volumes to equivalent oil
barrels at a ratio of 6 thousand cubic feet of gas to 1 barrel of oil.

BOPD . Barrels of oil per day.

Btu. British thermal unit. One British thermal unit is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

Developed oil and gas reserves . Developed oil and gas reserves are reserves of any category that can be expected to be recovered: (i) through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii)2 through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

Development project . A development project is the means by which petroleum resources are brought to the status of economically producible. As examples, the development of a single reservoir or field, an incremental development in a producing field or the integrated development of a group of several fields and associated facilities with a common ownership may constitute a development project.

Development well . A well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive.

Differential . An adj ustment to the price of oil or gas from an established spot market price to reflect differences in the quality and / or location of oil or gas.

Economically producible . The term economically producible, as it relates to a resource, means a resource which gen erates revenue that exceeds, or is reasonably expected to exceed, the costs of the operation. The value of the products that generate revenue shall be determined at the terminal point of oil and gas producing activities. The terminal point is generally reg arded as the outlet valve on the lease or field storage tank.

Estimated ultimate recovery (EUR) . Estimated ultimate recovery is the sum of reserves remaining as of a given date and cumulative production as of that date,

Exploratory well . A we ll drilled to find a new field or to find a new reservoir in a field previously found to be productive of oil or gas in another reservoir. Generally, an exploratory well is any well that is not a development well, an extension well, a service well or a stratigraphic tes t well.

Farmout. An assignment of an interest in a drilling location and related acreage conditional upon the drilling of a well on that location.

Gas. Natural gas.

MBb l

. One thousand barrels of oil or other liquid hydrocarbons.

MBOE. One thousand BOE.

Mcf. One thousand cubic feet of gas.

Mcfd. One thousand cubic feet of gas per day

MMcfe. One million cubic feet of gas equivalent.

MMBOE. One million BOE.

MMBtu. One million British thermal units.

MMcf. One million cubic feet of gas.

NYMEX. New York Mercantile Exchange.3 Oil. Crude oil, condensate and natural gas liquids.

Operator. The individual or company responsible for the exploration and / or production of an oil or gas
well or lease.

Play. A geographic area with hydrocar bon potential.

Polymer

. The purpose of the polymer gel treatment is to reduce excessive water production and increase oil or gas production from wells that produce from water

- drive reservoirs. These wells are typically produced from naturally fractured carbonate reservoirs such as dolomites and limestone in mature fields. Successful treatments are also run in certain types of sandstone reservoirs. Other practical applications of polymer gels include the treatment of waterflood injection wells to correct channeling or change the injection profile, to improve the ability of the injected fluids to sweep the producing wells in the field, making the waterflood much more efficient and allowing the operator to recover more oil in a shorter period of time.

Proved oil and gas reserves. Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known re servoirs, and under existing economic conditions, operating methods, and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of
whether deterministic or probabilistic methods are used for estimation. The project to extract the hydrocarbons must have commenced, or the operator must be reasonably certain that it will commence the project, within a reasonable time.

The area of the reservoir c onsidered as proved includes all of the following : (i) the area identified by drilling and limited by fluid contacts, if any; and (ii) adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil and gas on the basis of available geoscience and engineering data.

In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons as seen in a well penetration unless geoscience, engineering or performance data and reliable technology establish a lower contact with reasonable certainty.

Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associ ated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering or performance data and reliable technology establish the higher contact with reasonable certainty.

Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when: (i) successful testing by a pilot project in an area of the reservoir with propertie s no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir or other evidence using reliable technology establishes the reasonable certainty of the engineering4 ana lysis on which the project or program was based; and (ii) the project has been approved for development by all necessary parties and entities, including governmental entities.

Existing economic conditions include prices and costs at which economic producib ility from a reservoir is to be determined. The price shall be the average price during the twelve

- month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first

- day

of

- the

- month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Proved reserve additions. The sum of additions to proved reserves from extensions, discoveries, improved recovery , acquisitions and revisions of previous estimates.

Reserves. Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known

a ccumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market and all permits and financing required to implement the project. Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves shou ld not be assigned to areas that are clearly separated from a known accumulation by a non

- productive reservoir (i.e., absence of reservoir, structurally low reservoir or negative test results). Such areas may contain prospective resources (i.e., potentiall y recoverable resources from undiscovered accumulations).

Reserve additions. Changes in proved reserves due to revisions of previous estimates, extensions, discoveries, improved recovery and other additions and purchases of reserves in

- place.

Reserve life. A measure of the productive life of an oil and gas property or a group of properties, expressed in years.

Royalty interest. An interest in an oil and gas lease that gives the owner of the interest the right to receive a portion of the production from the leased acreage (or of the proceeds of the sale thereof), but generally does not require the owner to pay any portion of the costs of drilling or operating the wells on the leased acreage. Royalties may be either landowner's royalties, which are reserved by the owner of the leased acreage at the time the lease is granted, or overriding royalties, which are usually reserved by an owner of the leasehold in connection with a transfer to a subsequent owner.

Standardized measure. The present value, discounted at 10% per year, of estimated future net revenues from the production of proved reserves, computed by applying sales prices use d in estimating proved oil and gas reserves to the year

- end quantities of those reserves in effect as of the dates of such estimates and held constant throughout the productive life of the reserves and deducting the estimated future costs to be
incurred in developing, producing and abandoning the proved reserves (computed based on year

- end costs and assuming continuation of existing economic conditions). Future income taxes are calculated by applying the appropriate year

- end statutory federal and state inco me tax rate with consideration of future tax rates already legislated, to pre

- tax future net cash flows, net of the tax basis of the properties involved and utilization of available tax carryforwards related to proved oil and gas reserves.5 SWD. Salt water disposal well

.
Undeveloped oil and gas reserves. Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditu re is required for recompletion. Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unles s the specific circumstances justify a longer time. Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, or by other evidence using reliable technology establishing reasonable certainty.

Waterflood

. A method of secondary recovery in which water is injec ted into the reservoir formation to displace residual oil. The water from injection wells physically sweeps the displaced oil to adjacent production wells.

Working interest. An interest in an oil and gas lease that gives the owner of the interest the right to drill for and produce oil and gas on the leased acreage and requires the owner to pay a share of the costs of drilling and production operations.

PART I

ITEM 1. BUSINESS.

History of the Company

The Company was initially organized in Utah in 1916 under a name later changed to Onasco Companies, Inc. In 1995, the Company changed its name from Onas co Companies, Inc. by merging into Tengasco, Inc., a Tennessee corporation, formed by the Company solely for this purpose. At the Company’s Annual Meeting held on June 11, 2011, the stockholders of the Company approved an Agreement and Plan of Merger prev iously adopted by the Company’s Board of Directors which provided for the merger of the Company into a wholly

- owned subsidiary formed in Delaware for the purpose of changing the Company’s state of incorporation from Tennessee to Delaware. The merger became effective on June 12, 2011 and the Company is now a Delaware corporation.

OVERVIEW

The Company is in the business of explor ation for and production of oil and natural gas. The Company’s primary area of oil exploration and production is in Kansas. The Co mp any’s primary area of

gas production is the Swan Creek field in Tennessee.6 The Company’s wholly

- owned subsidiary, Tengasco Pipeline Corporation (“TPC”) owns and operates a 65

- mile intrastate pipeline which it constructed to transport natural gas from the Company’s Swan Creek Field to customers in Kingsport, Tennessee.

The Company’s wholly

- owned subsidiary, Manufactured Methane Corporation (“MMC”) operates treatment and delivery facilities using the latest developments in available tre atment technologies for the extraction of methane gas from nonconventional sources for delivery through the nation ’ s existing natural gas pipeline system, including the Company’s p ipeline system in Tennessee for eventual sale to natural gas customers

.

The Company also ha d a management agreement with Hoactzin Partners, L.P. (“Hoactzin”) to manage Hoactzin’s oil and gas properties in the Gulf of Mexic o offshore Texas and Louisiana (See below, “General 4 . Management Agreement with Hoactzin ” )

. Peter E. Sala s, 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 Offshore Partners, L.P., which is the Compan y’s largest shareholder. This management agreement expired on December 18,

2012.

General

1. The Kansas Properties

The Kansas Properties are located in central Kansas and as of December 31, 2012 include 1 96 producing oil wells , 21 shut

- in wells, and 37 active disposal wells

. Our management and staff have a great deal of Kansas exploration and production experience. We have onsite production management and field personnel working in Kansas.

In 201 2 , the Company continued to focus on both development an d exploration drilling. Many of
the wells that were drilled were on leases that are still in effect because they are being held by existing production. The leases provide for a landowner royalty of 12.5%. Some wells are subject to an overriding royalty interest from 0.5% to 9%. Other than such wells bearing overriding royalties, the Company maintains a 100% working interest in most of its older wells and any undrilled acreage in Kansas. The terms for most of the Company’s newer leases in Kansas are fro m three to five years.

Dur ing 201 2 , the Company drilled 2 0 gross wells. The Company has a 100% working interest in
all of the wells

. The success rate of the 20 wells drilled by the Company in Kansas was 75% resulting in

1 5 producers and 5 dry h oles

.
Kansas as a whole is of major significance to the Company. The majority of the Company’s current reserve value, current production, revenue, and future development objectives are centered in the Company’s ongoing interest in Kansas. By using 3

- D seismic evaluation on existing locations owned by the Company in Kansas, the Company has added and continues to add proven direct offset locations.

A. Kansas Ten Well Drilling Program

On September 17, 2007, the Company entered into a ten well drilling program with Hoactzin

,7 consisting of three wildcat wells and seven developmental wells to be drilled on the Company’s Kansas Properties (the “Program”). Under the terms of the Program, Hoactzin paid the Company $0.4 million for
each producing we ll a nd $0.25 million for each per dry hole . The terms of the Program also provide d tha t
Hoactzin would receive all the working interest in the producing wells , and w ould pay an initial fee to the Company of 25% of its working interest revenues net of operating expenses

, referred to as a management
fee

. The fee paid to the Company by Hoactzin will increase to an 85% working interest when net revenues received by Hoactzin reach an agreed payout point of approximately 1.35 times Hoactzin’s purchase price (the “Payout Point”)

.

N ine of the ten wells in the program were completed as oil producers and during the 4 th quarter
201 2 had gro ss production of approximately 3 6 barrels per day in total. Hoactzin paid a total of $3

. 85
million (the “Purchase P rice”) for its interest in the P rogram resulting in the Payout Point being determined as $5

. 2 million . The Purchase Price paid by Hoactzin for its interest in the Program wells
exceeded the Co mpany’s actual drilling cost of approximately $2.6 million for the ten wells by more than $1 million.

In 20 1 2

, the wells from the Program produced 1 4.3 MBbl of which 9.1 MBbl were net to
Hoactzin. As of December 31, 20 1 2 , net revenues received by Hoactzi n from the Program total ed $ 4.6 million which leaves a balance of $ 0.6 million until the Payout Point is reached

.
Although production level of the Program wells will decline over time in accordance with expected decline curves

, based on the drilling results of the Program wells to date and the current price of oil, the Program wells are now expected to reach the Payout Point by late 2013 or early 2014 . However,
under the terms of the agreement reaching the Payou t Po i nt could be accelerated by applying 75% of the net profits Hoactzin receives from the methane extraction project developed by MMC at the Carter Valley, Tennessee landfill (the “Methane Project ” ) , toward reaching the Payout Point. (The Methane Project is discussed i n greater detail below.)

The reserve information for the parties’ respective Ten Well Program interests as of December 31, 201 2 is indicated in the table below. Reserve reports are obtained annually and estimates related to those reports are updated upo n receipt of the report. These calculations were made using commodity prices based on the twelve month arithmetic average of the first day of the month price for the period January through December 201 2 as required by SEC regulations. The table below reflects eventual pay as occurring through the realization of proceeds at prices used in the reserve report dated December 31, 201 2 of approximately $ 88. 08 per barrel.8 Reserve Information fo r Ten Well Program Interest as of December 31, 201 2

B. Kansas Production

The Company’s gross oil production in Kansas in creased from 241 MBbl in 2011 to 279 MBbl in
20 1 2

. Approximately 30 MBbl of the 279 MBbl in 2012 were related to production from the 15 successful wells drilled during 2012 and approximately 44 MBbl were related to production increases as a
result of the 12 polymer s that were performed during 2012. These increases were partially offset by normal production declines.

The c apital projects undertaken by the Company in 2012 were initially funded by borrowings from the Company credit facility . However, these additional borrowings under the Company’s c redit facility were repaid by December 31, 2012

.

2. The Tennessee Properties

In the early 1980’s Amoco Production Company owned numerous acres of oil and gas leases in the Eastern Overthrust in the Appalachian Basin, including the area now referred to as the Swan Creek Field. Amoco successfully drilled tw o natural gas discovery wells in the Swan Creek Field to the Knox
Formation. In the mid

- 1980’s, however, development of this f ield was cost prohibitive due to a
substantial decline in worldwide oil and gas prices which was further exacerbated by the high cost of constructing a necessary 23

- mile pipeline to deliver gas from the Swan Creek Field to the close s t market. In July 1995, the Company acquired the Swan Creek leases and began development of the field.

As of December 31, 2012, t he Company has evaluated Swan Creek and nearby properties for the purpose of determining the value of continued development. In addition, the Company has evaluated the likelihood of realizing additional revenues from tran sportation of third party gas. As a result of these evaluations, Management has determined that Swan Creek and Pipeline are no longer considered core properties to the Company

. At December 31, 2012, the Company was in the process of negotiating the
sale of the Swan Creek and Pipeline assets. On March 1, 2013, the Company entered into an agreement
with Swan Creek Partners LLC to sell the Company’s Swan Creek and Pipeline assets for $1.5 million. Final closing of this transaction is contingent upon custom ary due diligence as well as certain regulatory and easement holder approvals.9 A. Swan Creek Pipeline Facilities

The Company’s completed pipeline system is owned and operated by TPC and extends 65 miles from the Swan Creek Field to several meter stations in Kingsport, Tennessee. The pipeline system was built for a total cost of $16.4 million. The Company reviews the carrying value of the pipeline for impairment whenever events and circumstances indicate that the carrying value of an asset may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition.
In cases whe re undiscounted expected future cash flows are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of assets. The factors considered by management in performing this assessme nt include current operating results, trends, and prospects, as well as the effects of obsolescence, demand, competition, and other economic factors. During 2010 there were indicators the pipeline may be impaired and the Company performed an
assessment of the carrying value as of December 31, 2010 based on expected future cash flows. The assessment resulted in the Company recording an impairment of approximately $5.0 million for the year ended December 31, 2010. At December 31, 201 2 management determined t hat an additional impairment of approximately $5.2 million was required. This determination at December 31, 2012 was based on negotiations with a third part y regarding the sale of the pipeline assets as well as the Company’s inability
to realize additiona l revenues from transportation of third party gas.

The carrying value of the pipeline has been classified in assets held for sale and the associat ed revenues and expenses net of taxes have been classified as discontinued operations. The carrying value of the pipeline included in assets held for sale was approximately $ 1.4 million and $ 6.9 million at December 31, 201 2 and 201 1 , respectively.

B. Swan Creek Production and Development

The Company has concluded based on the results of previously drilled wells and seismic data that drilling new gas wells in the Swan Creek Field would not achieve any significant increase in daily gas production totals from the Field . C urrent wells in production in the Swan Creek Field would be capable of and would likely produce all the remaining reserves in that Field. As a result, the Company has not drilled any new gas wells in the Swan Creek Field since 2004.

Because no drilling for natural gas in the Knox formation in Swan Creek is anticipated in the future, the current production levels less decline are the sole value of natural gas reserves and natural gas producti on. The existing production from the current wells producing natural gas are showing typical Appalachian productio n declines, which exhibit a long

- lived nature but more modest volumes. The experienced decline in actual production levels from existing wells in the Swan Creek Field was expected and predictable. Although there can be no assurance, the Company expects t hese natural rates of decline in the future will be comparable to historical decline experienced over the 20 10

- 201 2 period

.
As the Swan Creek assets represent only a small portion of the Company’s full cost pool, these asset will remain in oil and gas prop erties and related operations will continue to be classified in continuing operations.10 D uring 201 2 , the Company had 1 4 producing gas wells and 4 producing oil wells in the Swan
Creek Field. G ross gas production from the Swan Creek Field d uring 201 2 average d 216 Mcfd compared

to 145 Mcfd in 20 1 1

. Gross o il sales volumes from the Swan Creek field during 201 2 averaged approximately 1 3 BOPD compared to 1 5 BOPD in 20 1 1

.
3. Methane Project

On October 24, 2006, the Company signed a twenty

- year Landfill Gas Sale and Purchase Agreement (the “Agreement”) with BFI Waste Systems of Tennessee, LLC (“BFI”), an affiliate of Allied Waste Industries (“Allied”). In 2008, Allied merged into Republic Serv ices, Inc. (“Republic”). The Company assigned its interest in the Agreement to MMC and provides that MMC will purchase the entire naturally produced gas stream being collected at the Carter Valley municipal solid waste landfill owned and operated by Republ ic in Church Hill, Tennessee and located about two miles from the Company’s pipeline. The Company installed a proprietary combination of advanced gas treatment technology to extract the methane component of the purchased gas stream. Methane is the princi pal component of natural gas and makes up about half of the purchased raw gas stream by volume. The Company constructed a pipeline to deliver the extracted methane gas to the Company’s existing pipeline (the “Methane Project”).

The total cost for the Meth ane Project, including pipeline construction, was approximately $4.5 million. The costs of the Methane Project were funded primarily by (a) the money received by the Company from Hoactzin to purchase its interest in the Ten Well Program which exceeded the Company’s actual costs of drilling the wells in that Program by more than $1 million; (b) cash flow from the Company’s operations; and (c) $0.8 million of the funds the Company borrowed under its then credit facility with Sovereign Bank of Dallas, Texas (“ Sovereign Bank”). Methane gas produced by the project facilities was initially mixed in the Company’s pipeline and delivered and sold to Eastman under the terms of the Company’s natural gas purchase and sale agreement with Eastman. The gas supply from thi s landfill is projected to grow over the years as the underlying operating landfill continues to expand and generate additional naturally produced gas, and for several years following the closing of the landfill, estimated by Republic to occur in 2041. Gas production will continue in commercial quantities up to approximately 14 years after closure of the landfill.

MMC declared startup of commercial operations on April 1, 2009. During the month of April, the facility produced and sold 14 MMcf of methane ga s to Eastman Chemical Company (“Eastman”) and was online about 91% of the calendar month. System maintenance and landfill supply adjustments accounted for the remainder of the time. On May 1, 2009, Eastman advised MMC that it was suspending
deliveries of the methane gas stream pending approval by the federal Environmental Protection Agency (“EPA”) of Eastman’s petition for inclusion of treated methane gas as natural gas within the meaning of the EPA’s continuous emission monitoring rules applicable to East man’s large boilers during the annual “smog season” beginning May 1 st of each year. Although Eastman had begun seeking this approval in February, 2009, with the assistance of the Air Quality Department of the Tennessee Department of
Environment and Conser vation, the EPA had not acted by May 1 , 2009 . Eastman furnished to the EPA information provided by MMC that establishes that the methane gas stream is better fuel under the rule standards than even “natural” gas, which is technically defined in the smog s eason rules to include gas11 being “found in geologic formations beneath the earth’s surface”. Because approval was not promptly received, MMC was forced to seek alternative markets for the methane gas stream.

The Company concluded an agreement for sale of the methane gas to Hawkins County Gas Utility District , a local utility commencing August 1, 2009 on a month to month basis

. Effective September 1, 2009 the Company also began sales of its Swan Creek gas production to Hawkins County
G as Utility District, because the physical mixing of Swan Creek natural gas with MMC’s methane gas caused Eastman to suspend deliveries of both categories of gas as mixed.

On August 27, 2009, the Company entered into a five

- year fixed price gas sales cont ract with Atmos Energy Marketing, LLC, (“AEM”) in Houston, Texas, a nonregulated unit of Atmos Energy Corporation (NYSE: ATO) for the sale of the methane component of landfill gas produced by MMC at the Carter Valley Landfill. The agreement provides for t he sale of up to 600 MMBtu per day. The contract was effective beginning with September 2009 gas production and ends July 31, 2014. The agreed contract price of over $6 per MMBtu was a premium to the then current five

- year strip price for natural gas on the NYMEX futures market.

MMC’s plant is capable of remain ing in operation for a full 24 hours per day. Daily production decreases during days when the plant operates less than 24 hours, whether due to any equipment or collection system supply issue. T he primary reason experienced for less

- than

- 24

- hour operation since April 2009 has been frequent spiking in the oxygen content in the raw gas collected by Republic and delivered to the plant, rather than being caused by equipment malfunctions in MMC’s plan t. Oxygen spikes shut down MMC’s equipment for safety reasons

, as high oxygen gas streams become explosive under the compression required in our treatment process. In mid

- 2010 the oxygen spikes increased from occasional spikes to an almost constant level of oxygen that caused longer downtime to our equipment. MMC’s plant had minimal production of sales methane during the fourth quarter of 2010 of approximately 5,500 MMBTU of methane gas for an average of 60 MMBTU per day. The MMC plant had no production of methane during the third quarter 2010. During the second quarter in 2010, the facility produced approximately 27,000 MMBtu of methane, an average of 300 MMBtu per day. In the first quarter of 2010, the facility had produced about 19,600 MMBtu, an aver age of 220 MMBtu per day.

These problems continued throughout 2011, with average production being 81MMBtu per day for
the twelve month period ending December 31 , 2011 or a total yearly production of 29,469 MMBtu. The final two months of 2011 had no produc tion at the methane plant, due to additions being made to MMC’s facility to allow installation and fueling of the electric generator described below.

In order to address the issue of significant plant downtime due to oxygen levels, MMC s ought to eliminate the recycling of a process methane gas stream within the methane plant. That recycling had the effect of increasing the oxygen percentages at plant inlet when it was recycled to the plant inlet in order to
extract some still

- remaining m ethane. By ceasing use of that recycle stream, methane extraction efficiency would be reduced, but run time would be increased by avoiding some oxygen

- caused shutdowns for safety. MMC determined the recycle gas stream could be repurposed to be used to f uel an electric generator onsite, which would offset electric utility costs at the methane plant, as well as providing an additional revenue source. In April 2011

, MMC purchased a Caterpillar genset from Parkway Services Group of Lafayette, Louisiana whic h was delivered in late 2011 and installed at the12 methane plant site for generation of electricity. Total cost of the generator including installation and interconnection with the power grid was approximately $1.1 million.

On January 25, 2012, MMC commen ced sales of electricity generated at the Carter Valley site of its methane extraction facilities. The electricity generated is sold under a ten year firm price contract with Holston Electric Cooperative, Inc., the local distributor, and Tennessee Valley Authority through TVA’s Generation Partners program. That program accepted generated renewable power only up to 999KW; MMC’s generation equipment is rated at 974 KW to maximize revenues under the favorable electricity pricing under the Generation Partners program. The price provision under this contract pays MMC the current retail price charged monthly to small commercial customers by Holston Electric Cooperative, plus a “green” premium of 3 cents per kilowatt hour (KWH). Current price paid to MMC is $.1 29 per KWH. The contract terminates in January 2022 but can be extended for an additional ten years at a purchase price to be negotiated at that time. Methane gas sales will continue under the Atmos contract simultaneously with electric ity sales and the same one

- eighth royalty on electricity revenues will be paid to the landfill owner as is paid on methane revenues . The electric generation also reduces oxygen input to the methane plant

. Although a portion of the gas used for generation of electricity wi ll not be available for methane extraction, the use of the gas for electricity generation is equivalent to sale of the methane for almost $15 per MMBtu, more than double the price currently received for methane sales and more than
four times the current natural gas spot market price. During 2012, the gas sales portion of MMC was online approximately 59% of the time resulting in gas sales revenues net of royalty of $0.219 million. During 2012, the electric sales portion of MMC was onli ne approximately 46% of the time resulting in electric sales revenues net of royalty of $0.447 million.

On September 17, 2007, Hoactzin, simultaneously with subscribing to participate in the Ten Well Program (the “Program”), pursuant to a separate agree ment with the Company was conveyed a 75% net profits interest in the Methane Project. Any net profits from the Methane Project, if received by Hoactzin, would be applied towards the determination of the Payout Point (as defined above) for the Ten Well Prog ram. When the Payout Point is reached from either the revenues from the wells drilled in the Program or the Methane Project or a combination thereof, Hoactzin’s net profits interest in the Methane Project will decrease to 7.5%. The agreed method of calcu lation of net profits takes into account specific costs and expenses as well as gross revenues for the project. As a result of the startup costs and ongoing operating expenses, and reduced production levels discussed above, no net profits as defined have been generated from project startup in April, 2009 through December 31, 201 2 for payment to Hoactzin under the net profits interest conveyed. As of the date of this report, all payments applied to reaching the Payout Point have been generated from the Pro gram.

4. Management Agreement with Hoactzin

On December 18, 2007, the Company entered into a Management Agreement with Hoactzin. On that same date, the Company also entered into an agreement with Charles Patrick McInturff employing

him as a Vice

- President of the Company. Pursuant to the Management Agreement with Hoactzin, Mr. McInturff’s duties while he is employed as Vice President of the Company include d the management on behalf of Hoactzin of its working interest in certain oil and g as properties owned by Hoactzin and located in the onshore Texas Gulf Coast, and offshore Texas and offshore Louisiana. As consideration for the Company entering into the Management Agreement, Hoactzin agreed that it would13 be responsible to reimburse the Company for the payment of one

- half of Mr. McInturff’s salary, as well as certain other benefits he receives during his employment by the Company. In further consideration for the Company’s agreement to enter into the Management Agreement, Hoactzin grante d to the Company an option to participate in up to a 15% working interest on a dollar for dollar cost basis in any new drilling or workover activities undertaken on Hoactzin’s managed properties during the term of the Management Agreement. The term of the Management Agreement ends on the earlier of the date Hoactzin sells its interest in its managed properties or five years (December 2012). The Management Agreement expired on December 18, 2012. As of the date of this Report, the Company is assisting Hoactzin with becoming operator of record of these wells and transferring the corresponding bonding liability from the Company
to Hoactzin. T he Company has entered into a transition agreement with Hoactzin whereby Hoactzin and its controlling member are indemnifying Tengasco for any costs or liabilities incurred by Tengasco resulting from such assistance, or the fact that Tengasco is still the operator of record on certain of these
wells.

The Compa ny became the operator of certain properties owned by Hoactzin in connection with the Management Agreement. The Company obtained from IndemCo, over time, bonds in the face amount of approximately $10.7 million for the purpose of covering plugging and aban donment obligations for operated properties located in federal offshore waters in favor of the Bureau of Ocean Energy Management (“BOEM”)

, as well as certain private parties. On October 12, 2012, the BOEM terminated $1.1 million of these bonds leaving a b alance of approximately $9.6 million at December 31, 2012.

In connection with the issuance of these bonds the Company entered into a Payment and Indemnity Agreement with IndemCo that guarantees payment of any bonding liabilities incurred by
IndemCo. Dol phin Direct Equity Partners, LP co

- signed the Payment and Indemnity Agreement, thereby becoming jointly and severally liable with the Company for the obligations to IndemCo. Hoactzin has provided $6.6 million in cash to IndemCo as collateral for the oblig ations. Dolphin Direct Equity Partners is a private equity fund controlled by Peter E. Salas that h a s a significant economic interest in
Hoactzin.

As operator, the Company ha d routinely contracted in its name for goods and services wit h vendors in connection with its operation of the Hoactzin properties. In practice, Hoactzin pa id directly these invoices for goods and services that are contracted in the Company’s name. During late 2009 and early 2010, Hoactzin undertook several significant operations, for which the Company contracted in the ordinary course. As a result of the ope rations performed in late 2009 and early 2010, Hoactzin currently has significant past due balances to several vendors, a portion of which are included on the Company’s
balance sheet. Payables related to these past due and ongoing operations remained outs tanding at the end
of 2012 and 2011 in the amount of $0.325 million and $ 0.265 million respectively. Because this amount is material, the Company has recorded the Hoactzin

- related payables and the corresponding receivable
from Hoactzin as of December 31

, 2012 and 2011 in its Consolidated Balance Sheets under “Accounts payable

– other” and “Accounts receivable

– related party”. During the quarter s ended September 30,
2012 and December 31, 2012 , Hoactzin ha d not made payments to reduce these past due balanc es. Based on these circumstances, the Company has elected to establish an allowance in the amount of $0.2 57
million of the $0.325 million balance outstanding at December 31 , 2012 . The $0.068 million difference between the balance and the allowance repres ent invoices paid by Hoactzin in early 2013

.14 The Company as designated operator was administratively issued an “Incidence of Non

Compliance” by BOEM concerning one of the Hoactzin wells operated by the Company pursuant to the Management Agreement . This a ction calls for payment of a civil penalty of $386,000 for the late filing of certain reports in 2011 by a contractor on the facility. The work to be reported had been timely performed, but the reports were not filed by the contractor. The contractor has since filed for bankruptcy. The Company was not at fault in this matter but is made administratively liable due to the status as designated operator of the well . The Company has filed an appeal of this action in order to attempt to significantly reduce the civil penalty. This appeal required a fully collateralized appeal bond to stay payment of the obligation until the appeal is determined. On November 1, 2012, t he Company posted and collateralized this bond with RLI Insurance Company. If the bond w as not posted, the appeal would be administratively denied and the order to the Company as operator to pay the $386,000 penalty would be final. While the Company believes it will ultimately prevail in the appeal process, it is reasonably possible to expec t that the Company may be required to pay a portion of this penalty. The Company estimates the range of this possible payment to be between zero and $386,000.

No funds have been advanced by Tengasco to pay any obligations of Hoactzin. No borrowing capability of Tengasco has been used by the Company in connection with its obligations under the Management Agreement

, except for those funds used to collateralize the appeal bond with RLI Insurance Company

. The Management Agreement expired on December 18, 2012.

5. Other Areas of Development

The Company may review potential acquisitions of additional existing oil and gas production in areas of Kansas, Oklahoma, and Texas. However, at the time of this report, the C ompany remains fully
focused on de velopment of the Company’s current Kansas holdings.

Govern mental Regulations

The Company is subject to numerous state and federal regulations, environmental and otherwise, that may have a substantial negative effect on its ability to operate at a profit. For a discussion of the risks involved as a result of such regulations, see, “Effect of Existing or Probable Governm ental Regulations
on Business and Costs and Effects of Compliance with Environmental Laws” hereinafter in this section.

Principal Products or Services and Markets

The principal markets for the Company’s crude oil are local refining companies. The principal markets for the Company’s natural gas and methane production are local utilities, private industry end

users, and gas marketing compani es.

At present , c rud e oil produced by the Company in Kansas is sold at or near the wells to Coffeyville Resources Refining and Marketing, LLC (“Coffeyville Refining”) in Kansas City, Kansas and to National Cooperative Refinery Associatio n (“NCRA”) in McPherson, Kansas. Both Coffeyville Refining and NCRA are solely responsible for transportation to their refiner ies of the oil they purchase. The Company may sell some or all of its production to one or more additional refineries in order to maximize revenues as purchases prices offered by the refineries fluctuate from time to time.15 Crude oil produced by the Company in Te nnessee is sold to Clearfield Appalachian (“Clearfield). Clearfield is solely responsible for transportation to the refinery of the oil they purchase.

Gas production from the Swan Creek Field can presently be delivered through the Company’s completed pipeline to th e Powell Valley Utility District in Hancock County, Hawkins County Gas Utility, Eastman and BAE in Sullivan County, other industrial customers in the Kingsport area, as well as gas marketing companies. The Company has acquired all necessary regulatory app rovals and necessary property rights for the pipeline system. The Company’s pipeline can provide transportation service not only for gas produced from the Company’s wells, but also for small independent producers in the local area as well or other pipelin es that may be connected to the Company’s pipeline in the future.

Drilling Equipment

The Company does not currently own a drilling rig or any related drilling equipment. The Company obtains drilling services as required from time to time from various c ompanies as available in the Swan Creek Field area and various drilling contractors in Kansas.

Distribution M ethods of Products or Services

Crud e oil is normally delivered to r efiner ies in Tennessee and Kansas by t ank truck and natural gas is distributed and transported by pipeline.

Competitive Business Conditions, Competitive Position in the Industry and Methods of Competition

The Company’s contemplated oil and gas exploration activities in the States of Tennessee and Kansas will be undertaken in a high ly competitive and speculative business atmosphere. In seeking any other suitable oil and gas properties for acquisition, the Company will be competing with a number of other companies, including large oil and gas companies and other independent operators with greater financial resources. Management does not believe that the Company’s competitive position in the oil and gas industry will be significant as the Company currently exists.

The Company has numerous competitors in the State of Tennessee that ar e in the business of exploring for and producing oil and natural gas in Kentucky and East Tennessee areas. Some of these companies are larger than the Company and have greater financial resources. These companies are in competition with the Company for l ease positions in the known producing areas in which the Company currently operates, as well as other potential areas of interest.

There are numerous producers in the area of the Kansas Properties. Some of these companies are larger than the Company and have greater financial resources. These companies are in competition with the Company for lease positions in the known producing areas in which the Company currently operates, as well as other potential areas of interest.

Although management does not for esee any difficulties in procuring contracted drilling rigs, several factors, including increased competition in the area, may limit the availability of drilling rigs, rig operators and related personnel and/or equipment in the future. Such limitations wou ld have a natural adverse impact on the profitability of the Company’s operations.16 The Company anticipates no difficulty in procuring well drilling permits in any state. They are usually issued within one week of application. The Company generally does not apply for a permit until it is actually ready to commence drilling operations.

The prices of the Company’s products are controlled by the world oil market and the United States natural gas market. Thus, competitive pricing beha viors are considered unlikely; however, competition in the oil and gas exploration industry exists in the form of competition to acquire the most promising acreage blocks and obtaining the most favorable process for transporting the product.

Sources and A v ailability of Raw Materials

Excluding the development of oil and gas reserves and the production of oil and gas, the Company’s operations are not dependent on the acquisition of any raw materials.

Dependence on One or a Few Major Customers

At present, cr ude oil from the Kansas Properties is being purchased at the well and trucked by Coffeyville Refining and NCRA, which are responsible for transportation of the crude oil purchased. The Company may sell some or all of its production to one or more addition al refineries in order to maximize revenues as purchase prices offered by the refineries fluctuate from time to time.

The Company is presently dependent upon a small number of customers for the sale of gas from the Swan Creek Field and the Methane Project

. These customers are principally gas marketing companies, utility districts, and industrial customers in the Kingsport area with which the Company may enter into gas sales contract s

.
Patents, Trademarks, Licenses, Franchises, Concessions, Royalty Agreements or Labor Contracts, Including Duration

On October 19, 2010, the Company’s subsidiary MMC was granted United States Patent No. 7,815,713 for Landfill Gas Purification Method and System, pursuant to application filed January 10, 2007. The paten t term is for twenty years from filing date plus adjustment period of 595 days due to the length of the review process resulting in grant of the patent. The patent is for the process designed and utilized by MMC at the Carter Valley landfill facility. Th e patent may result in a competitive advantage to MMC in seeking new projects, and in the receipt of licensing fees for other projects that may be using or wish to use the process in the future. However, the limited number of high Btu projects currently

e xisting and operated by others, the variety of processes available for use in high Btu projects, and the effects of current gas markets and decreasing or inapplicable green energy incentives for such projects in combination cause the materiality of any lic ensing opportunity presented by the patent to be difficult to determine or estimate, and thus the licensing fees from the patent, if any are received, may not be material to the Company’s overall results of operations.

Need For Governmental Approval of Pri ncipal Products or Services

None of the principal products offered by the Company require governmental approval, although permits are required for drilling oil or gas wells. In addition the transportation service offered by TPC is subjec t to regulation by the Tennessee Regulatory Authority to the extent of certain construction, safety,17 tariff rates and charges, and nondiscrimination requirements under state law. These requirements are typical of those imposed on regulated common carrier s or utilities in the State o f Tennessee or in other states. TPC presently has all required tariffs and approvals necessary to transport natural gas to all customers of the Company.

The City of Kingsport, Tennessee has enacted an ordinance granting to TP C a franchise for
twenty years (expires June 20, 2020 ) to construct, maintain and operate a gas system to import, transport, and sell natural gas to the City of Kingsport and its inhabitants, institutions and businesses for domestic, commercial, industrial and institutional uses. This ordinance and the franchise agreement it authorizes also require approval of the Tennessee Regulatory Authority under state law. The Company will not initiate the required approval process for the ordinance and franchise agr eement until such time that it can supply gas to the City of Kingsport. Although the Company anticipates that regulatory approval would be granted, there can be no assurances that it would be granted, or that such approval would be granted in a timely man ner, or that such approval would not be limited in some manner by the Tennessee Regulatory Authority.

Effect of Existing or Probable Governmental Regulations on Business

Exploration and pr oduction activities relating to oil and gas leases are subject to numerous environmental laws, rules and regulations. The Federal Clean Water Act requires the Company to construct a fresh water containment barrier between the surface of each drilling site and the underlying
water table. This involves the insertion of s teel casing into each well, with cement on the outside of the casing. The Company has fully complied with this environmental regulation, the cost of which is approximately $10,000 per well.

The State of Tennessee also requires the posting of a bond to en sure that the Company’s wells are properly plugged when abandoned. A separate cash $ 2,000 bond is required for each well drilled. The Company currently has the requisite amount of cash bonds in effect and are secured by a certificate of deposit in the am ount of $120,500.

As part of the Company’s purchase of the Kansas Properties , the Company acquired a statewide permit to drill in Kansas. Applications under such permit are applied for and issued within one to two weeks prior to drilling. At the present time, the State of Kansas does not require the posting of a bond either for permitting or to insure that the Company’s wells are properly plugged when abandoned. All of the wells in the Kansas Properties have all permits required and the Company believes that it is in compliance with the laws of the State of Kansas.

The Company’s exploration, production and marketing operations are regulated extensively at the federal, state and local levels. The Company has made and will continue to ma ke expenditures in its
efforts to comply with the requirements of environmental and other regulations. Further, the oil and gas regulatory environment could change in ways t hat might substantially increase these cost s . These regulations affect the Company’s operations and limit the quantity of hydrocarbons it may produce and sell. Other regulated matters include marketing, pricing, transportation and valuation of royalty
payments.18 The Company’s operations are also subject to numerous and frequently changing laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. The Company owns or leases, and has in the past owned or leased, properties that have been used for the exploration and production of o il and gas and these properties and the wastes disposed on these properties may be subject to the Comprehensive Environmental Response,
C ompensation and Liability Act, the Oil Pollution Act of 1990, the Resource Conservation and R ecovery Act , the Federal Water Pollution Control Act and analogous state laws. Under such laws, the Company
could be requ ired to remove or remediate prev iously released wastes or property conta mination.

Laws and regulations protecting the environment have generally become more stringent and, may in some cases, impose “strict liability” for environmental damage. Strict liability means that the Company may be held liable for damage without regar d to whether it was negligent or otherwise at fault. Environmental laws and regulations may expose the Company to liability for the conduct of or conditions caused by others or for acts that were in compliance with all applicable laws at the time they wer e performed. Failure to comply with these laws and regulations may result in the imposition of administrative, civil and criminal penalties.

While management believes that the Company’s operations are in substantial compliance with existing requirements of governmental bodies, the Company’s ability to conduct continued operations is subject to satisfying applicable regulatory and permitting controls. The Company’s current permits and authorizations and ability to get future permits and authorizations may be susceptible, on a going forward basis, to increased scrutiny, greater complexity resulting in increased costs or delays in receiving appropriate authorizations.

The Company maintains an Environmental Response Policy and Emergency Action Response
Polic y Program. A plan was adopted which provides for the erection of signs at each well and at strategic locations along the pipeline containing telephone numbers of the Company’s office. A list is maintained at the Company’s office and at the home of key personnel listing phone numbers for fire, police, emergency services and Company employees who will be needed to deal with emergencies.

The foregoing is only a brief summary of some of the existing environmental laws, rules and regulations to which the Co mpany’s business operations are subject, and there are many others, the effects of which could have an adverse impact on the Company. Future legislation in this area will no
doubt be enacted and revisions will be made in current laws. No assurance can be given as to that affect these present and future laws, rules and regulations will have on the Company’s current and future operations.

The risk factors described below are not exhaustive and you are encouraged to perform your own investigation with respect to the Company and its business. You should also read the other information included in this Form 10

- K, including the financial stat ements and related notes.

The Company’s indebtedness, global recession s , and disruption in the domestic and global financial markets could have an adverse effect on the Company’s operatin g results and financial condition.

As of Decembe r 31, 20 1 2

, the outstanding principal amount of the Company’s indebtedness under its credit facility with F&M Bank & Trust Company (“F&M Bank”) was approximately $ 1 0.1 million. The level of indebtedness, coupled with domestic and global economic conditions , the associated volatility of energy prices, and the l evels of disruption and continuing relative illiquidity in the credit markets may, if continued for an extended period, have several important and adverse consequences on the Company’s busine ss and operations. For example, any one or more of these factors could (i) make it difficult for the Company to service or refinance its existing indebtedness; (ii) increase the Company’s vulnerability to additional adverse changes in economic and industr y conditions; (iii) require the Company to dedicate a substantial portion or all of its cash flow from operations and proceeds of any debt or equity issuances or asset sales to pay or provide for its indebtedness; (iv) limit the Company’s ability to

respon d to changes in our businesses and the markets in which we operate; (v) place the Company at a20 disadvantage to our competitors that are not as highly leveraged; or (vi) limit the Company’s ability to borrow money or raise equity to fund our working capita l , capital expenditures, acquisitions, debt service requirement s , investments, general corporate activity or other financing needs. The Company continues to closely monitor the disruption in the global financial and credit markets, as well as the signific ant volatility in the market prices for oil and natural gas. As these events unfold, the Company will continue to evaluate and respond to any impact on Company operations. The Company has and will continue to adjust its drilling plans and capital expendi tures as necessary. However, external financing in the capital
markets may not be readily available, and without adequate capital resources, the Company’s drilling and other activities may be limited and the Company’s business, financial condition and results of operations may suffer. Additionally, in light of the credit markets and the volatility in pricing for oil and nat ural gas, the Company’s ability to enter into future beneficial relationships with third parties for exploration and production activities may be limited, and as a result, may have an adverse effect on current operational strategy and related business init iatives.

Agreements G overning the Company’s I ndebtedness may L imit the Company’s A bility to E xecute
C apital S pending or to R espond to O ther I nitiatives or O pportunities as they May A rise.

Because the availability of borrowings by the Company under the ter ms of the Company’s amended and restated credit facility with F&M Bank is subject to an upper limit of the borrowing base as determined by the lender’s calculated estimated future cash flows from the Company’s oil and natural gas

reserves , the Company expects any sharp decline in the pricing for these commodities, if continued for any extended period, would very likely result in a reduction in the Company’s borrowing base. A reduction in the Company’s borrowing base could be significant a nd as a result, would not only reduce the capital available to the Company but may also require repayment of principal to the lender under the terms of the facility. Additionally, the terms of the Company’s amended and restated credit facility with
F&M B an k restrict the Company’s ability to incur additional debt. The credit facility contains covenants and other restrictions customary for oil and gas borrowing base credit facilities, including limitations on debt, liens, and dividends , voluntary redemptions of debt, investments, and asset sales. In addition, the credit facility requires that the Company maintain compliance with certain financial tests and financial covenants. If future debt financing is not available to the Company when required as a resul t of limited
access to the credit markets or otherwise, or is not available on acceptable terms, the Company may be unable to invest needed capital for drilling and exploration activities, take advantage of business opportunities, respond to competitive pr essures or refinance maturing debt. In addition, the Company may be forced to sell some of the Company’s assets on an untimely basis or under unfavorable terms. Any of these results could have a material adverse effect on the Company’s operating results and financial
conditions.

The Company’s Borrowing Base Under its Credit Facility May be Reduced by the L ender

.

The borrowing base under the Company’s revolving credit facility will be determined from time to time by the lender, consistent with its customary natural gas and crude oil lending practices. Reductions in estimates of the Company’s natural gas and crude oil reserves could result in a reduction in the Company’s borrowing base, which would reduce the amount of financial resources available under the Company’s revolving credit facility to meet its capital requirements. Such a reduction could be the
result o f lower commodity prices or production, inability to drill or unfavorable drilling results, changes21 in natural gas and crude oil reserve engineering, the lender’s inability to agree to an adequate borrowing base or adverse changes in the lender ’ s practice s regarding estimation of reserves.

If either cash flow from operations or the Company’s borrowing base decreases for any reason, the Company’s ability to undertake exploration and development activities could be adversely affected.

As a result, the Compan y’s ability to replace production may be limited. In addition, if the borrowing base is reduced, it would be required to pay down its borrowings under the revolving credit facility so that outstanding borrowings do not exceed the reduced borrowing base. Th is requirement could further reduce the cash available to the Company for capital spending and, if the Company did not have sufficient capital to reduce its borrowing level, could cause the Company to default under its revolving credit facility

The Company ’s Credi t Facility i s Subject to Variable Rates of Interest, Which Could Negatively Impact the Company.

Borrowings under the Company’s credit facility with F&M Bank are at variable rates of interest and expose the Company to interest rate risk. If intere st rates increase, the Company’s debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and the Company’s income and cash flows would decrease. The Company’s credit facility
agreement c ontains certain financial covenants based on the Company’s performance. If the Company’s financial performance results in any of these covenants being violated, F&M Bank may choose to require repayment of the outstanding borrowings sooner than currently r equired by the agreement.

Declines in Oil or Gas Prices H ave and Will Materially Adversely Affect the Company ’s Revenues.

The Company’s financial condition and results of operations d epend in large part upon the pri ces obtainable for the Company’s oil and natural gas production and the costs of finding, acquiring, developing and producing reserves. As seen in recent years, prices for oil and natural gas are subject to extreme fluctuations in response to changes in supply, market uncertainty and a variety of additional factors that are beyond the Company’s control. These factors include worldwide political instability (especially in the Middle East and other oil producing regions), the foreign supply of oil and gas, the price of foreign imports, th e level of drilling activity, the level of consumer product demand, government regulations and taxes, the price and availability of alternative fuels speculating activities in the
commodities markets and the overall economic environment. The Company’s ope rations are substantially adversely impacted as oil prices decline. Lower prices dramatically affect the Company’s revenues from its drilling operations. Further, drilling of new wells, development of the Company’s leases and acquisitions of new properti es are also adversely affected and limited. As a result, the Company’s potential revenues from operations as well as the Company’s proved reserves may
substan tially decrease from levels achieved during the period when oil prices were much higher. There can be no assurances as to the future prices of oil or gas. A substantial or extended decline in oil or gas prices would have a material adverse effect on the Company’s financial position, results of operations, quantities of oil and gas that may be econo mically produced, and access to capital. Oil and natural gas prices have historically been and are likely to continue to be volatile.22 This volatility makes it difficult to estimate with precision the value of producing properties in

ac quisitions and to budget and project the return on exploration and development projects involving the Company ’ s oil and gas properties. In addition, unusually volatile prices often disrupt the market for oil and gas properties, as buyers and sellers have more difficulty agreeing on the purchase price of properties.

Risk in Rates of Oil and Gas Production, Development Expenditures, and Cash Flows May Have a Substantial Impact on the Company’s Finances.

Projecting the effects of commodity prices on production, and timing of development expenditures include many factors beyond the Company’s control. The future estimates of net cash flows from the Company’s proved and other reserves and their present value are based upon various assumptions about futu re production levels, prices, and costs that may prove to be incorrect over time. Any significant variance from assumptions could result in the actual future net cash flows being materially different from the estimates, which would have a significant impa ct on the Company’s financial position.

The Company has a History of Significant Losses.

During the early stages of the development of its oil and gas business the Company had a history of significant losses from operations, in particular its development of the S w an Creek Field, an d has an
accumulated deficit of $ 25. 6 million as of December 31, 20 1 2

. In 2009, t he Company recorded a net loss of $2.0 million. In 2010, the Company had a profit before pipeline impairment of $ 1.3 million, but due to

a non

- cash pipeline impairment of $5 million ($ 3.3 million net of tax effects) the Company recorded a net loss of $ 1.7 million. The Company also recorded a $0.6 million non

- cash unrealized gain on derivatives ($0.4 million net of tax effects). Net of both the non

- cash impairment and the non

- cash unrealized gain on derivatives the Company would have recorded an adjusted net income of $0.9 million. In 2011, the
Com pany recorded net income of $4.7 million

. In 2012, the Company recorded a net loss of $0.1 million primarily due to a non

- cash pipeline impairment of $5.2 million or $3.4 million net of tax effects

. In the event the Company experiences losses in the future, those losses may curtail the Company’s development and operating acti vities.

The Company’s Oil and Gas Operations Involve Substantial Cost and are Subject to Various
Economic Risks.

The Company’s oil and gas operations are subject to the economic risks typically associated with exploration, development, and production acti vities, including the necessity of making significant expenditures to locate or acquire new producing properties or to drill exploratory and developmental wells. In conducting exploration and development activities, the presence of unanticipated pressure or irregularities in formations, miscalculations, and accidents may cause the Company’s exploration, development, and production activities to be unsuccessful. This could result in a total loss of the
C ompany’s investment in such well (s) or property. In addition, the cost of drilling, completing and operating wells is often uncertain.23 The Company’s Failure to Find or Acquire Additional Reserves Will Result in the Decline of the Company’s Reserves Materially From Their Current Levels.

T he rate of production from the Company’s Kansas oil and Tennessee oil and natural gas properties generally declines as reserves are depleted. Except to the extent that the Company either acquires additional properties containing proved reserves, conducts successful exploration and development drilling, or successfully applies new technologies or identifies additional behind

- pipe zones or secondary recovery reserves, the Company’s properties proved reserves will decline materially as production from these p roperties continues. The Company’s future oil and natural gas production is therefore highly dependent upon the level of success in acquiring or finding additional reserves or other alternative sources of production. Any decline in oil prices and any pro longed period of lower prices will adversely impact the Company’s future reserves since the Company is less likely to acquire additional producing properties during such periods. The lower oil prices have a chilling effect on new drilling and development as such activities become far less likely to be profitable. Thus, any acquisition of new properties poses a greater risk to the Company’s financial conditions as such acquisitions may be commercially unreasonable

.

In addition, the Company’s drilling for oil and natural gas may involve unprofitable efforts not only from dry wells but also from wells that are productive b ut do not produce sufficient volumes to be commercially profitable after deducting drilling, operating , and other costs. Also , wells that are profitable may not achieve a targeted rate of return. The C ompany relies on seismic data and other technologies in identifying prospects and in conducting exploration activities. The seismic data and other technologies used do not allow the Company to know conclusively prior to drilling a well whether oil or natural gas is present or may be produced economically.

The ultimate costs of drilling, completing, and operating a well can adversely affect the economics of a project. Further drilling operations may be curtailed, delayed or canceled as a result of numerous factors, including unexpected drilling conditions, title problems, pressure or irregularities in formations, equipment failures

, accidents, adverse weather conditions, environmental and other governmental requirements and the cost of, or shortages or delays in the availability of drilling rigs, equipment, and services.

The Company’s Reserve Estimates May Be Subject to Other Material Downward Revisions.

The Company’s oil and natural gas reserve estimates may be subject to material downward
revisions for additional reasons other than the factors mentioned in the previ o u s risk factor entitled “The Company’s Failure to Find or Acquire Additional Reserves Will Result in the Decline of the C ompany’s

Reserves Materially from their Current L evels. ” While the f uture estimates of net cash flows from the Company’s proved reserves and their present value are based upon assumptions about future production levels, prices, and costs that may prove to be incorrect over time, those same assumptions, whether or not they prove to be correct, may cause the Company to make drilling or developmental decisions that will
result in some or all of the Company’s proved reserves to be removed from time to time f rom the proved reserve categories previously reported by the Company. This is particularly so if the price of oil declines sharply as it did during the period from mid

- 2008 through January 2009.24 This may occur because economic expectations or forecasts, together with the Company’s limited resources, may cause the Company to determine that drilling or development of certain of its properties may be delayed or may not foreseeably occur, and as a result of such decisions any ca tego r y of proved reserves relating t o those yet undrilled or undeveloped properties may be removed from the Company’ s reported prove d reserves. Consequently, the C ompany ’ s proved reserves of oil or of gas, or both, may be materially revised downward from time to time. As an example, the Company’s proved Swan Creek gas

reserves calculation has been revised downward in the past as a result of removal of portions of the Company’s reported gas reserves from the “proved undeveloped category ” (“PUD”) and the “prove d developed nonproducing” (“PDNP”) categories . This downward revision was based on the Company’s determination that additional drilling or development of Swan Creek may not occur in the f oreseeable
future because the economic returns from such drilling or development would not be favorable when compared to the costs and anticipated results of such activity . Although that particular revision at this time will not have a significant impact on overall results of operations in view of th e relatively small portion of the Company’s current business and assets founded in Swan Creek, other future revisions in oil
and gas reserves, may be significant and materially reduce oil or gas reserves.

In addition, the Company may elect to sell some or all of its oil or gas reserves in the normal
course of the Company’s business. Any such sale would result in all categories of those proved oil or gas
reserves that were sold no longer being reported by the Company

.
There is Risk That the Company May Be R equired to Write Down the Carrying Value of its Natural Gas and Crude Oil Properties.

The Company uses the full cost method to account for its natural gas and crude oil operations. Accordingly , the Company capitalizes the cost to acquire, explore for and develop natural gas and crude
oil properties

. Under full cost accounting rules, the net capitalized cost of natural gas and crude oil properties and related deferred income tax if any may not exceed a “ceiling limit” which is based upon the present value of estimated future net cash flows from proved reserves, discounted at 10% , p lus cost of properties not being amortized and the lower of cost or estimated fair value of unproven proper ties included in the cost being amortized. If net capitalized cost of natural gas and crude oil properties
exceed s the ceiling limit, the Company must charge the amount of the excess, net of any tax effects, to earnings. This charge does not impact cash flow from operating activities, but does reduce the Company’s stockholders ’ equity an d earnings. The risk that the C ompany will be required to write

- down the carrying value of natural gas and crude oil properties increases when natural gas and crude oil p r i ces are low. In addition, write

- downs may occur if the Company experiences substantial downward adjustments to its estimated proved reserves . An expense recorded in a period may not be reversed in a subsequent period even though higher natural gas and crude oil prices may have increased the ceiling applicable to the subsequent period

.

There is a Risk That the Company M ay Be Required to Write Down the Carrying Value of its Pipeline or Methane Facilities.

The Company’s Pipeline and Methane facility assets are subject to review for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable.25 The carrying amount is not recoverable if it exceeds the sum of the undiscounted cash flo ws expected to result from the use and eventual disposition of the pipeline or methane facility assets. Should this occur, the assets carrying amount will be reduced to its fair value and the excess over fair value to net of any tax effects, will be charg ed to earning s . This expense may not be reversed in future periods

. During 2010 and
2012 , the Company incurred w ritedown s of its pipeline asset of $5.0 million and $5.2 million, respectively and approximately $ 3.3 million and $ 3.4 million net of tax effect in 2010 and 2012

, respectively

. Th ese wr itedown s resulted from the Company’s assessment that cash flows generated from the pipeline were insufficient to recover the pipeline’s net book value. During the fourth quarter of 2010
and 2012

, the Company received expressions of interest from potential purchasers of the pipeline asset which were significantly below the asset’s pre

- writedown net book value

. These expressions of interest as well as the Company’s inability to realize additional rev enues from transportation of third party gas indicated that the carrying amount of the pipeline may not be recoverable. The carrying value of the pipeline asset at December 31, 2012 is approximately $ 1.4 million. The pipeline asset is classified as an

as set held for sale.

Use of the Company’s Net Operating Loss Carryforwards May Be Limited.

At December 31, 20 1 2 , the Company had, subject to the limitations discussed in this risk factor

, substantial amounts of net operating loss carryforwards for U.S. federal and state income tax purposes.
These loss carryforwards will eventually expire if not utilized. In ad dition, as to a portion of the U.S. net operating loss carryforwards, the amoun t of such carryforwards that the Company can use annually is
limited under U.S. ta x laws

. Uncertainties exist as to both the calculation of the appropriate deferred tax
assets based upon the existence of these loss carryforwards, as well as the future uti lization of the operating loss carryforwards under the criteria set forth under FASB ASC 740, Income Taxes . In addition,
limitations exist upon use of these carryforwar d s in the event of a change in control of the Company
occurs. There are risks that the Company ma y not be able to utilize some or all of the remaining carryforwards, or that deferred tax assets that were previously booked based upon such carryforwards may be written down or reversed based on future economic factors that may be experienced by the Company. The effect of such write downs or reversals, if they occur, may be material and substantially
adverse.

Shortages of Oil Field Equipment, Services and Qualified Personnel Could Adversely Affect the Company’s Results of Operations

.
The demand for qualified and experienced field personnel to drill wells and conduct field operations, geologist s , geophysicists, engineers and other professionals in the oil and natural gas industry can fluctuate significantly, often in correlation with oil and natural gas prices, causing periodic shortages. The Company does not own any drilling rigs and is dependent upon third parties to obtain and provide such equipment as needed for the Company’s drilling activities. There have also bee n shortages of drilling rigs and other equipment when oil prices have risen . As prices increased, the demand for rigs and equipment increase d along with the number of wells being drilled. These factors also cause significant increases in costs for equipm ent, services and personnel. Higher oil prices in Kansas have currently
stimulate d and increased demand and this has result ed in increased prices for drilling rigs, crews and associated supplies, equipment and services , as well as increased potential that the Company’s experienced employee base in Kansas conducting field operations may be offered employment by26 competing companies and the Company may not be capable of replacing such departing personnel at existing salary levels, or at all. These shortages or price increases could adversely affect the Company’s profit margin, cash f low, and operating results or restrict the Company’s ability to drill wells and conduct ordinary operations.

The Company has Significant Cost s to Conform to Govern ment Regulation of the Oil and Gas Industry.

The Company’s exploration, production, and marketing operations are regulated extensively at the federal, state and local levels. The Company is currently in compliance with these regulations. In order to maintain its compliance, the Company has made and will have to continue to make substantial expenditures in its efforts to comply with the requirements of environmental and other regulations. Further, the oil and gas regulatory environment could change in ways that might substantially increase these costs. Hydrocarbon

- producing states regulate conservation practices and the protection of correlative right s. These regulations affect the Company’s operations and limit the quantity of hydrocarbons it may produce and sell. Other regulated matters include marketing, pricing, transportation and valuation of royalty payments.

The Company has Significant Costs Related to Environmental Matters.

The Company’s operations are also subject to numerous and frequently changing laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. The Company owns or leases, and has owned or leased, properties that have been leased for the exploration and production of oil and gas and these properties and the wastes disposed on these properties may be subject to the Comprehensive Environmental Response, Compen sation and Liability Act, the Oil Pollution Act of 1990, the Resource Conservation and Recovery Act, the Federal
Water Pollution Control Act and similar state laws . Under such laws

, the Company could be required to remove or remediate wastes or property c ontamination.

Laws and regulations protecting the environment have generally become more stringent and, may in some cases, impose “strict liability” for environmental damage. Strict liability means that the Company may be held liable for damage without r egard to whether it was negligent or otherwise at fault.
Environmental laws and regulations may expose the Company to liability for the conduct of or conditions caused by other s or for acts that were in compliance with all applicable laws at the time they were performed . Failure to comply with these laws and regulations m ay result in the imposition of administrative, civil and criminal penalties.

The Company’s ability to conduct continued operations is subject to satisfying applicable regulatory and perm itting controls. The Company’s current permits and authorizations and ability to get future permits and authorizations may be susceptible, on a going forward basis, to increased scrutiny, greater complexity resulting in increased cost or delays in receivi ng appropriate authorizations.

Insurance Does Not Cover All Risks.

Exploration for and development and production of oil and natural gas and the Company’s transportation and other activities can be hazardous, involving unforeseen occurrences such as blowouts,
fires and loss of well control , which can result in damage to or destruction of wells or production27 facilities, injury to persons, loss of life or da mage to property or to the environment. Although the Company maintains insurance against certain losses or liabilities arising from its operations in accordance with customary industry practices and in amounts that management believes to be pru dent, insur ance is
not available to the Company against all operational risks.

The Company’s Methane Extraction Operations from Non

- conventional Reserves Involve Substantial Cost and are Subject to Various Economic, Operational, and Regulatory Risks.

The Company’s o perations in projects involving the extraction of methane gas from non

conventional reserves such as landfill gas streams, require investment of substantial capital and are subject to the risks typically associated with capital intensive operations, includ ing risks associated with
the availability of financing for r equired equipment, construction schedules, air and water environmental permitting, and locating transportation facilities and customers for the products produced from those operations which may d elay or prevent startup of such projects. After startup of commercial operations, the presence of unanticipated pressures or irregularities in constituents of the raw materials used in such projects from time to time, miscalculations or accidents may caus e the Company ’s project activities to be unsuccessful. Although the technologies to be utilized in such projects is believed to be effective and economical, there are operational risks in the use of such technologies in the combination to be utilized by

t he Company as a result of both the combination of technologies and t h e early stages of commercial development and use of such technologies for methane extraction f ro m non

- conventional sources such as those to be used by the Company. This risk could result in total or partial loss of the Company’s
investment in such projects . The economic risks of such projects include the marketing risks resulting from price volatility of the methane gas produced from such projects, which is similar to the pr ice volatility of natural gas. These projects are also subject to the risk that the products manufactured m ay not be accepted for transportation in common carrier gas transportation facilities

, although the products meet specified requirements for such tr ansportation, or may be accepted on such terms that reduce the returns of such projects to the Company. These projects are also subject to the risk that the product manufactured may not be accepted by purchasers thereof from time to time and the viability of such projects would be dependent upon the Company’s ability to locate a replacement market for physical delivery of the gas produced from the project.

The Company’s methane extraction business is the subject of a patent granted to the Company.

There can be no assurance that our existing patent will not be invalidated, circumvented or challenged, or that we will be issued any patents sought in the future, or that the rights granted or to be granted under any patents will provide us competitive advantag es.

We have been granted one U.S. patent and have a continuation U.S. patent application pending relating to certain aspects of our methane extraction technology and we may seek additional patents on
future innovations. Our ability to license our technology is substantially dependent on the validity and enforcement of this patent. We cannot assure you that our patent will not be invalidated, circumvented or challenged, that patents will be issued for our continuation patent pending, th at the rights granted under the patents will provide us competitive advantages, or that our current and future patent a pplications will be granted. In addition, third parties may seek to challenge, invalidate, circumvent or render unenforceable any patent s or proprietary rights owned by or licensed to us based on, among other things: subsequently discovered prior art; lack of entitlement to the priority of an earlier, related application; or28 failure to comply with the written description, best mode, enable ment or other applicable requirements. If a third party is successful in challenging the validity of our patent, our inability to enforce our intellectual property rights could materially harm our methane extraction business. Furthermore, our technology m ay be the subject of claims of intellectual property infringement in the future. Our technology may not be
able to withstand third

- party claims or rights against their use.

Any intellectual property claims, with or without merit, could be time

- consuming, expensive to litigate or settle, could divert resources and attention and could require us to obtain a license to use the intellectual property of third parties. We may be unable to obtain licenses from these third parties on favorable terms, if at all. Even if a license is available, we may have to pay substantial royalties to obtain
a license. If we cannot defend such claims or obtain necessary licenses on reasonable terms, we may be precluded from offering most or all of our technology and our methane extraction business may be adversely affected.

The Company Faces Significant Competition with Respect to Acquisitions or Personnel.

The oil and gas business is highly competitive. In seeking any suitable oil and gas properties for acquisition, or drilli ng rig operators and related personnel and equipment, the Company is a small entity with limited financial resources and may not be able to compete with most other companies, including large oil and gas companies and other independent operators with greate r financial and technical resources and longer history and experience in property acquisition and operation.

The Company Depends on Key Personnel, Whom it May Not be Able to Retain or Recruit.

Jeffrey R. Bailey, the Company’s Chief Executive Officer, othe r members of present management and certain Company employees have substantial expertise in the areas of endeavor presently conducted and to be engaged in by the Company specifically including engineering, petrophysical analysis, and well completion design . To the extent that their services become unavailable,
the Company would be required to retain other and additional qualified personnel to perform these multiple services in several technical areas upon which the Company is dependent to conduct explorati on and production activities . The Company does not know whether it would be able to recruit and h ire qualified and additional persons upon acceptable terms. The Company does not maintain “Key Person”
insurance or retention agreements for any of the Compa ny’s key employees.

The Company’s Operations are Subject to Changes in the General Economic Conditions.

Virtually all of the Company’s operations are subject to the risks and uncertainties of adverse changes in general econ omic conditions, the outcome of potential legal or regulatory proceedings, changes in environmental, tax, labor and other laws and regulations to which the Company is subject, and the condition of the capital markets utilized by the Company to finance its operations.

Being a Public Compa ny Significantly Increases the Company’s Administrative Costs.

The Sarbanes

- Oxley Act of 2002, as well as rules subsequently implemented by the SEC and listing requirements subsequently adopted by the NYSE MKT , the exchange on which the Company’s stock is traded, in response to Sarbanes

- Oxley, have required changes in corporate governance practices, internal control policies and audit committee practices of public companies. Although the Company is a29 relatively small public company

, th ese rules , regulations, and requirements for the most part apply to the

same extent as they apply t o all major publicly t raded companies. As a result, they have significantly
increased the Company’s legal, financial, compliance and administrative costs, an d have made certain
other activities more time consuming and costly , as well as requiring substantial time and attention of our senior management. The Company expects its continued compliance with these and future rules and regulations to continue to requ ire significant resources. These rules and regulations also may make it more difficult and more expensive for the Company to obtain director and officer liability insurance in the future, and co uld make it more difficult for it t o attract and retain quali fied members for the Comp a n y’ s Board of Directors, particularly to serve on its audit committee.

The Com pany’s Chairman of the Board Beneficially Controls a Substantial Amount of the Company’s Common Stock and Has Significan t Influence over the Company’s B usiness.

Peter E. Salas, the Chairman of the Company ’ s Board of Directors, is the sole shareholder and controlling person of Dolphin Management, Inc. the general partner of Dolphin Offshore Partners, L.P. (“Dolphin”) , and a member of SSB Ventures LLC (“SS B”) which is the Company ’s largest shareholder.

At March 15, 2013 , Mr. Salas through Dolphin and SSB controls 21,057,492 shares of the Company’s common stock and had options granting him the right to acquire an additional 1 50,000 shares of common
stock. His ownership and voting control o f approximately 3 5 % of the Company’s common stock gives him significant influence on the outcome of corporate transactions or other matters submitted to the Board of Directors or shareholders for approval, including merger s, consolidations and the sale of all or substantially all of the Company’s assets.

Shares Eligible for Future Sale May Depress the Company’s Stock Price.

As of March 1 5

, 201 3 the Company had 60, 842 ,413 shares of common stock outs tanding of
which 22, 076,212 shares were held by affiliates . I n addition, options to purchase 991,000 shares of unissued common stock were granted under the Tengasco, Inc. Stock Incentive Plan of whi ch options to purchase 831,000 shares were vested at March 1 5 , 201 3

.

All of the shares of common stock held by affiliates are restricted or controlled securities under Rule 144 promulgated under the Securities Act of 1933, as amended (the “Securities Act”). The shares of the common stock issuable upon exercise of the s t ock optio ns have been registered under the Securities Act. Sales of shares of common stock under Rule 144 or another exemption under the S ecurities Act or pursuant to a registration statement could have a material adverse effect on the price of the common stock

an d could impair the Company’s ability to raise addition al capital through the sale of equity securities.

Future Issuance of Additional Shares of the Company’s Common Stock Could Cause Dilution of Ownership Interest and Adversely Affect Stock Price.

The Comp any may in the future issue prev iously authorized and unissued securities, resulting in the dilution of the ownership interest of its current stockholders. The C ompany is currently authorized to
issue a total of 100 million shares of common stock with such rights as determined by the Board of Directors. Of that amount, approximately 61 million shares have been issued. The potential issuance of the approximately 39 million remaining authorized but unissued shares of common stock may create30 downward pressure on the trading price of the Company’s common stock.

The Company may also issue additional shares of its common stock or other securities that are convertible into or exercisable for common stock for rai sing capital or other business purposes. Future
sales of substantial amounts of common stock, or the perception that sales could occur, could have a material adverse effect on the price of the Company’s common stock.

The Company May I ssue Shares of Prefer red Stock w ith Greater Rights than Common
Stock.

Subject to the rules of the NYSE MKT , the Company’s charter authorizes the B oard of D irectors

t o issue one or more series of preferred stock and set the terms of the preferred stock without seeking any
furt her approval from holders of the Company’s common stock. Any preferred stock that is issued may rank ahead of the Company’s common stock in terms of dividends, priority and liquidation premiums and may have greater voting rights than the Company’s common stock.

Kansas Properties

The Kansas Properties as of December 31, 20 12 contained approximately 20,600 gross acres in the vicinity of Hays, Kansas. Of these 20,600 gross acres, 13,751 acres were held by production and 6,849 acres were undeveloped.

I n 20 1 2 , the Company continued to focus on retaining properties with geologic value

. Many of these leases are still in effect because they are being held by production. The se leases provide for a royalty of 12.5%. Some wells are subject to an overriding royalty interest from 0.5% to 9%. T he Company maintains a 100% working interest in most of its older wells and any undrilled acreage in
Kansas. The primary term for most of the Co mpany’s newer leases in Kansas is from three to five years31 from the date of the lease.

During 201 2 , the Company drilled and completed as producers 1 5 wells

, and also drilled 5 dry
ho les in Kansas

.
Kansas as a whole is of major significance to the Company. The majority of the Company’s current reserve value, current production, revenue, and future development objectives are centered in the Company’s ongoing interest s in Kansas

. By using 3

Reserve Analyses

The Company’s estimated total net proved reserves of oil and nat ural gas as of December 31,
201 2 and 20 1 1 , and the present values of estimated future net revenues attributable to those reserves as of those dates, are presented in the following tables. All of the Company’s reserves were located in the United States. These estimates were prepared by LaRoche Pet roleum Consultants, Ltd. (“LaRoche”) of Dallas, Texas, and are part of their reserve reports on the Company’s oil and gas properties. LaRoche and its employees and its registered petroleum engineers have no interest in the Company and performed
those ser vices at their standard rates. LaRoche’s estimates were based on a review of geologic, economic, ownership, and engineering data provided to them by the Company. In accordance with SEC regulations, no price or cost escalation or reduction was considered. The technical persons at LaRoche responsible for

Historically, all drilling has primarily been funded by cash flows from operations with supplement al funding provided by the Company’s credit facility

. During 201 2 , approximately 57 MBbl of proved undeveloped reserves that existed at December 31, 20 1 1 were converted into proved developed reserves from drilling and completion

. All proved undeveloped reserves included in the Company’s
report at December 31, 201 2 and 20 1 1 related to oil prospects in Kansas. During 20 1 1

, approximately
140 M Bbl of proved undeveloped reserves that existed at December 31, 20 10 were converted into proved developed reserves.35 The oil and natural gas prices after basis adjustments used in our December 31, 20 1 2 reserve valuation were $ 88. 08 per Bbl and $ 2.76 per Mcf. The oil and natural gas prices after basis adjustments used in our December 31, 20 1 1 reserve valuation were $ 88.53 per Bbl and $4. 16 per Mcf. The per Bbl
decrease in oil price and the reduction of i dentifi ed proved undeveloped locations were the primary
factor s in the decreased 20 1 2 reserve volumes and values as compared to 20 1 1 level s

. ( Refer to Note 16

, Supplemental Oil and Gas Information, Standardized Measure of Discounted F uture Net Cash Flows in the Company’s Notes to Consolidated Financial Statements for additional reserve information. )

The prices used in calculating the estimated future net revenue attributable to proved reserves do not reflect market prices for natural gas and oil production sold subsequent to December 31, 20 1 2 . There can be no assurance that all of the estimated proved reserves will be produced and sold at the assumed prices. Ac cordingly, the foregoing prices should not be interpreted as a prediction of future prices.

I n substance, the LaRoche Report used estimates of oil and gas reserves based upon standard petroleum engineering methods which include production data, decline cu rve analysis, volumetric calculations, pressure history, analogy, various correlations and technical factors. Information for this purpose was obtained from owners of interests in the areas involved, state regulatory agencies, commercial services, outside operators and files of LaRoche.

Management has established, and is responsible for, internal controls designed to provide reasonable assurance that the estimates of Proved Reserves are computed and reported in accordance with SEC rules and regulations as well as with established industry practices. The Company’s CEO and the Vice President responsible for management of Hoactzin’s properties located offshore Texas/Louisiana each have extensive professional engineering experience evaluating both domestic and international reserves on a well by well basis and on a company wide basis. Prior to generation of the annual reserves

,

mana gement and staff meet with LaRoche to review properties and discuss assumptions to be used in the calculation of reserves. Management reviews all information submitted to LaRoche to ensure the accuracy of the data. Management also reviews the final report from LaRoche and discusses any differences from Management expectations with LaRoche.36 Production

AND RESULTS OF OPERATIONS

Results of Operations

The Company reported net income from continuing operations of $ 4. 2 million or $ 0.0 7 per share
in 201 2 compared to net income from continuing operations of $ 5.0 million or $0.0 8 per share in 201 1
and net income from continuing operations of $ 1. 9 million or $0.0 3 per share in 20 10

. The Company reported a net loss from discontinued operations of $ ( 4.3 ) million or $ ( 0.07 ) per share in 2012 compared

to a net loss from discontinued operations of $ (0.2 9 ) million or $ ( 0.0 0) per share in 2011 and a net loss from discontinued operations of $ (3. 7 ) million or $ ( 0.0 6) per share in 20 10

. The net loss es from discontinued operations in 2012 and 2010 w ere primarily due to impairments of the Company’s pipeline
assets i n the amount s of approximately $ 3. 4 million and $ 3. 3 million, respectively

. Discontinued operations are net of associated taxes.

The Company realized revenues of $ 20.6 million in 201 2 compared to $ 17.1 million in 20 1 1 and $ 13.2 million in 20 10

. During 2012, revenues increased $3.5 million of which $3.3 million related to

increases in oil sales volumes from 189.5 MBbl in 2011 to 226.6 MBbl in 2012. In addition, Methane Project revenues increased $0.5 million in 2012 primarily from electricity sales which commenced in January 2012. These increases were partially offset by a $(0.3) million decrease related to a $(1.21) per

barrel decrease i n the average oil price received from $88.13 per barrel in 2011 to $86.92 per barrel

received in 2012. During 2011, r evenues increa sed $ 3. 9 million from 2010 of which $2.8 million related to a $16.01 per barrel in crease in the average oil price received f rom $72.14 per barrel in 2010 to $ 88.15 per barrel in 201 1 and $1.2 million related to increase s in sales volumes primarily from drilling and polymers

. These increase s in 2011 were partially offset by a $(0.1) million decrease in Methane Project

revenues.

Gas prices received for sales of gas from the Swan Creek Field averaged $3.35 per Mcf in 2012, $4. 28 per Mcf in 201 1

, and $ 4.90 per Mcf in 2010

. Oil prices received for sales of oil from the Swan Creek field averaged $88.29 per barrel in 2012, $ 87.33 p er barrel in 201 1

, and $ 71.05 per barrel in 20 10

.
The Company’s p rod uction cost s and taxes w ere $7. 18 million in 2012, $ 5.94 million in 201 1

, and $ 5.85 million in 2010

. The $1. 24 million increase in 2012 was primarily due to a $0.3 million

increase in Kansas field expenses

, a $0.29 million incr ease in Kansas property taxes, and a $0.26 million

increase in Methane Project costs

.
Depreciation, d epletion, and amortization was $3. 4 million in 2012, $2. 5 million in 2011

, and $2. 2 million in 20 10

. The $0.9 million increase in 2012 was primarily related to higher oil and gas depletion expense due to increased sales volumes and an increase in the depletion rate

.
The Company’s general and administrative cost w as $2. 6 million in 2012 and $ 2.3 million in
each 2011 and 2010

. The $0. 3 million increase in 2012 was primarily related to a $0.26 million

allowance recorded in 2012 for Hoactzin related receivables , a $0.1 million increase in tax preparation and consulting costs related to reviews o f prior year tax returns, a $0.1 million increase in non

- tax consulting cost, partially offset by a $(0.17) million decrease in bonus cost

.43 The 2012, 20 1 1

, and 20 10 cost included non

- cash charges related to stock options of $0.05 million, $0.2 million

, and $ 0. 1 million , respectively.

Interest expense was $0.74 million in 2012, $0.6 4 million in 201 1

, and $0.6 6 million in 2010

. The increase in interest expense in 2012 was due to increased borrowings from the Company’s credit facility with F&M Bank to s upplement funding of material inventory purchases in early 2012 and to supplement funding of the Company’s 2012 drilling and polymer program. Although the credit facility balance at December 31, 2012 was $1.4 million lower than the balance at December 31, 2011, the average balance during 2012 was approximately $1.9 million higher than the average borrowing during 2011. Interest was applied against these balances at an annual rate of 5.25%.

During 2012, the Company recorded a $(0.14) million loss on deriv atives. The 2012 loss on derivatives was comprised solely of an unrealized loss. During 2011, the Company recorded a $(0.4 1 )
million loss on derivatives. The 2011 loss was comprised of a $0.45 million unrealized gain, offset by $ ( 0.86 ) million of settle ment payments made to Macquarie Bank Limited (“Macquarie”) pursuant to a hedging agreement it entered into with Macquarie in August 2009 (see, Item 7A, “Commodity Risk”). During 2010, the Company recorded a $0.5 million gain on derivatives. The gain was comp ri sed of a $0.6 million unrealized gain partially offset by $0.1 million of settlement payments made to Mac quarie.

In 2012 and in 2010, the Company recorded non

- cash impairments of its pipeline assets in the
amounts of $5 .2 million ($ 3. 4 million net of tax effect) and $5 million ($ 3. 3 million net of tax effect)

, respectively

. The pipeline assets are classified as assets held for sale in the Company’s Consolidated
Balance Sheets. Th ese write down s resulted from the Company’s assessment that cash flow s generated from the pipeline were insufficient to recover the pipeline’s net book value. During 2012 and 2010 the Company received expressions of interest from potential purchasers of the pipeline asset which were significantly below the asset’s pre write down net book value s . These expressions of interest indicated that the carrying amount of the pipeline may not be recoverable. At December 31, 2012, the Company was in the process of negotiating an agreement to sell the pipeline assets and the Swan Creek Field wells and associated equipment. Preliminary allocation of the sales value to the pipeline assets indicated a write down of approximately $5.2 million, before tax effect, was necessary.

The Company recorded income tax expen se on continuing o perations of $ 2. 3 million in 2012, $ 0.3 million in 2011, and an income tax expense of $ 0.8 million in 2010

. The tax expense in 2011 was impacted by removal of the $1.7 million valuation allowance. Had this valuation allowance not been removed the Company would have recorded tax expense of $ 2.0 million in 2011. (See Note 14

. ) Income Taxes in Notes to Consolidated Financial Statements)

Liquidity and Capital Resources

At December 31, 2012 , the Company had a revolving credit facility with F&M Bank & Trust Company (“F&M Bank”). Under the credit facility, loans and letters of credit are available to the Company on a revolving basis in an amount outstandin g not to exceed the lesser of $4 0 million or the Company’s borrowing base in effect from ti me to time. As of December 31, 2012, the Company’s borrowing base was $21.5 million. The borrowing base was reduced to $20.5 million with the March 6, 2013 amendment to the credit agreement. The credit facility is secured by substantially all of the Comp any’s producing and non

- producing oil and gas properties and pipeline and the Company’s Methane44 Project assets. The credit facility includes certain covenants with which the Company is required to comply. These covenants include leverage, interest cover age, minimum liquidity, and general and administrative coverage ratios. During 2012 and 2011 the Company was in compliance with all

covenants.

On March 14, 2012, the Company’s senior credit facility with F&M Bank after F&M Bank’s
semiannual review of the Company’s then owned producing properties was amended to increase the Company’s borrowing base from $20 million to $23 million and extend the term of the facility to January 27, 2014. The interest rate remained the greater of prime plus 0.25% or 5.25% per annum. The Company’s interest rate at December 31, 2012 was 5.25%.

On September 12, 2012, the Company’s senior credit facility with F&M Bank after F&M Bank’s semiannual review of the Company’s then owned producing properties was amended to decrease the Company’s borrowing base from $23 million to $21.5 million. The term of the facility and interest rate remained unchanged.

On January 31, 2013, the Company’s senior credit facility with F&M Bank was amended to revise the “Change in Control” definition. N o other changes we re made to the credit facility.

On March 6, 2013 , the Company’s senior credit facility with F&M Bank after F&M Bank’s semiannual review of the Company’s then owned producing properties was amended to reduce the Company’s borrowing base from $2 1.5 million to $2 0.5 million and extend the term of the facility to January 27, 201 5 . The interest rate remained the greater of prime plus 0.25% or 5.25% per annum.

The total borrowing by the Company under the facility at December 31, 2012 and D ecember 31,

2011 was $ 10.1 million and $ 11.5 million, respectively. The next borrowing base review will take place
in June 2013

.

Although the Company has not been required as of the date of this Report to make any payment

o f principal t o F&M B ank under the borrowing base in effect at any time, the Company can make no assurance that in view of the conditions in the national and world economies, including the realistic possibility of low commodity prices being received for the Company’s oil and gas product ion for
extended periods, that F&M may in the future make a redetermination of the Company’s borrowing base to a point below the level of the installment or other payments to F&M in such amount and at such times in order to reduce the principal of the Company’s outstanding borrowing to a level not in excess of the borrowing base as it may be re dete rmined.

During 20 1 2 and 20 1 1

, the Company focused on increasing its oil production and carefully used
its cash flow and available credit to do so. However, the Company can make no assurance that it can continue normal operations indefinitely or for any specific period of time in the event of extended periods
of low commodity prices , such as occurred in late 2008 and early 2009, or upon the o ccurrence of any significant downturn or losses in operations. In such event, the Company may b e required to reduce costs of operations by various means, including not undertaking certain maintenance or reworkin g operations that may be necessary to keep some of the Company’s properties in production or to seek additional45 working capital by additional means such as issuance of equity including preferred stock or such other means as may be considered and authorized by the Company’s Board of Directors from time to time.

Net cash provided by operating activities from continuing operations was $9. 3 million in 2012, $8. 7 million in 2011, and $4. 2 million in 2010

. Net cash used in operating activities from discontinued operations was $(0.29) million in 2012, $(0.24) million in 2011, and $ (0.16) million in 2010

. The increase in cash provided by operating activities from continuing operations in 2012 was primarily due to a $3.3 million increase related to increased sales volumes , partially offset by a $(1.3) million increase in production costs and taxes and a $(1.2) million decrease in changes in working capital . The increase in cash provided by operating activities from continuing operations in 2011 was primarily due t o a $4.0

million increase related to higher oil prices and increased sales volumes as well as $0.6 increase to changes in working capital

. Cash flow used in working capital was $( 1.1 ) million in 2012, $0.3 million

was prov ided by working capital in 2011, a nd $(0. 4 ) million was used for working capital in 2010

. The
difference in change s in working capital in 2012 as compared to 2011 was primarily related a decrease in accounts payable related primarily to a reduction in year

- end drilling and polymer activity compared to 2011, posting of cash collateral related to the appeal bond, and an increase in equipment and materials inventory. The difference in changes in working capital in 2011 as compared to 2010 was primarily
related to an increase in accounts payable related primarily to increases in year

- end drilling and polymer activity compared to 2010.

Net cash used in investing activit ies from continuing operations was $7.6 million in 2012, $10.4 million in 2011, and $ 3. 7 in 2010

. The $2.8 million decrease in investing activities in 2012 as compared to 2011 was due to a $1.2 million decrease in derivative cost, receipt of a $1.0 millio n payment in lieu of tax credits related to the methane facility, a $0.35 million reduction in capital spending related to the Methane Facility, and a $0.2 million reduction in drilling and polymer cost. The $(6. 7 ) million increase

in investing activities in 2011 as compared to 2010 w as primarily due to a $(4.8) million increase in drilling and polymer spending, $ ( 0.8 ) million of additional capital used to purchase and install an electric generator at the Methane Facility , and a $(1.2) million increase in derivative related costs

. T he Company was required to make $ ( 0.86 ) million of derivative settlement payments to Macquarie as well as a $ ( 0 .37 ) million payment to Cargill Incorporated (“Cargill”) to purchase a $65 floor (See Item 7A. “Commodity
Risk” for a discussion of the agreement with Cargill )

.

In 2012, $(1. 8 ) million was used in financing activities from continuing operations to pay down the Company’s credit facility. In 2011, $1. 6 million was provided by financing activities from continuing operation s from bank funding which was used primarily to fund drilling and polymer activities during
2011. In 2010, $0. 75 million of cash was used in financing activities from continuing operations related primarily to the Company entering into a sweep account arr angement allowing excess cash balances to be used to temporarily pay down the credit facility, thereby, reducing overall interest cost. Net cash provided by financing activities from discontinued operations was $0.29 million in 2012, $0.24 million in

2011 , and $0.18 million in 2010. This funding was used to finance the Company’s pipeline operations.

Critical Accounting Policies

The Company prepares its Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America, which require the Company to make estimates and assumptions that affect the reported amounts of assets a nd liabilities and disclosures of

## Tengasco, Inc. and Subsidiaries
Notes to Cons olidated Financial Statements

46 contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the year. Actual results could differ from those estimates. The Company considers the fo llowing policies to be the most critical in understanding the judgments that are involved in preparing the Company ’s financial statements and the uncertainties that could impact the Company’s results of operations, financial condition and cash flows.

Reven ue Recognition

Revenues are recognized based on actual volumes of oil , natural gas , methane gas, and electricity sold to purchasers at a fixed or determinable price, when delivery has occurred and title has transferred, and collectability is reasonably as sured. Crude oil is stored and at the time of delivery to the purchasers, revenues are recognized. Natural gas meters are placed at the customer’s location and usage is billed each month. There were no material natural gas imbalances at December 31, 201 2

. Methane gas and electricity sales meters are located at the tailgate of the Company’s Methane Facility and sales are billed each month.

Full Cost Method of Accounting

The Company follows the full cost method of accounting for oil and gas property

acq uisition, exploration, and development activities. Under this method, all costs incurred in connection with acquisition, exploration and development of oil and gas reserves are capitalized. Capitalized costs include lease acquisitions, seismic related co sts

, certain internal exploration

costs, drilling, completion, and estimated asset retirement costs. The capitalized costs of oil and gas properties, plus estimated future development costs relating to proved reserves and estimated asset retirement costs, which are not already included net of est imated salvage value, are
amortized on the unit

- of

- production method based on total proved reserves. The Company has determined its reserves based upon reserve reports provided by LaRoche Petroleum Consultants
Ltd. in 2012, 201 1 , 20 10 , and 200 9 . The costs of unproved properties are excluded from amortization until the properties are evaluated, subject to an annual assessment of whether impairment has occurred. The Company ha d $0.457 million and $0.268 million in unevaluated properties as of December 31, 20 12 and 201 1, respectively . Proceeds from the sale of oil and gas properties are accounted for as reductions to capitalized costs unless such sales cause a significant change in the relationship between costs and the estimated value of proved reserves, in which case a gain or loss is recognized. At the end of each reporting period, the Company performs a “ceiling test” on the value of the net capitalized cost of oil and gas properties. This test compares the net capitalized cost (capitalized cost of oil an d gas properties, net of accumulated depreciation, depletion and amortization and related deferred income taxes) to the present value of estimated future net revenues from oil and gas properties using an average price (arithmetic average of the beginning o f month prices for the prior 12 months) and current cost discounted at 10% plus cost of properties not being amortized and the lower of cost or estimated fair value of unproven properties included in the cost being amortized (ceiling).

Oil and Gas Reserves/Depletion Depreciation and Amortization of Oil and Gas Properties47 The capitalized costs of oil and gas properties, plus estimated future development costs relating to proved reserves and estimated costs of plugging and abandonment, net of costs relating to proved reserves and estimated costs of plugging and abandonment, net of estimated salvage value, are amortized on the
unit

- of

- production method based on total proved reserves. The costs of unproved properties are excluded from amortization until the properties are evaluated, subject to an annual assessment of whether impairment has occurred.

The Company’s proved oil and gas reserves as of December 31, 2012 were determined by LaRoche Petroleum Consultants, Ltd. P rojecting the effects of commodity prices on production, and timing of development expenditures includes many factors beyond the Company’s control. The future estimates of net cash flows from the Company’s proved reserves and their present value are based upon various assumptions about future production levels, prices, and costs that may prove to be incorrect over time. Any significant variance from assumptions could result in the actual future net cash flows being materially different from the estimates.

Asset Retirement Obligations

The Company’s asset retirement obligations relate to the plugging, dismantling and removal of wells drilled to date. The Company follows the requirements of FASB ASC 410, “ Asset Retirement Obligations and Environmental Obligat ions ” . Among other things, FASB ASC 410 requires entities to record a liability and corresponding increase in long

- lived assets for the present value of material obligations associated with the retirement of tangible long

- lived assets. Over the passage of time, accretion of the liability is recognized as an operating expense and the capitalized cost is depleted over
the estimated useful life of the related asset

. If the estimated future cost of the asset retirement obligation changes, an adjustment is reco rded to both the asset retirement obligation and the long

- lived asset. Revisions to estimated asset retirement obligations can result from changes in retirement cost estimates,
revisions to estimated inflation rates and changes in the estimated timing of a bandonment. The Company currently use s an estimated useful life of wells ranging from 30

- 40 years

. Management continues to periodically evaluate the appropriateness of these assumptions.

Income Taxes

Income taxes are reported in accordance with U.S. GAAP, which requires the establishment of deferred tax accounts for all temporary differences between the financial reporting and tax bases of assets and liabilities, using currently enacted federal and sta te income tax rates. In addition, deferred tax accounts must be adjusted to reflect new rates if enacted into law. Temporary differences result principally from federal and state net operating loss carryforwards, differences in oil and gas property
value s resulting from a 2008 ceiling test write down, differences in pipeline values resulting from a 2010
and a 2012 impairment, and differences in methods of reporting depreciation and amortization. Management routinely assesses the ability to realize our de ferred tax assets and reduces such assets by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not
be recognized.48 At December 31, 2012, federal net operating loss carryforwards a mounted to approximately $21.8 million which expire between 2019 and 2031. The total deferred tax asset was $ 9.4 million and $10.2 million at December 31, 2012 and 2011, respectively.

Realization of deferred tax assets is contingent on the generation of f uture taxable income. As a result, management considers whether it is more likely than not that all or a portion of such assets will be realized during periods when they are available, and if not, management provides a valuation allowance
for amounts not likely to be recovered.

Management periodically evaluates tax reporting methods to determine if any uncertain tax positions exist that would require the establishment of a loss contingency. A loss contingency would be recognized if it were probable that a liability has been incurred as of the date of the financial statements and the amount of the loss can be reasonably estimated.

The amount recognized is subject to estimates and management’s judgment with respect to the likely outcome of each uncert ain tax position. The amount that is ultimately incurred for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount recognized.

Although management considers our valuation allowance and loss contingency as of December 31, 2012 and 2011 adequate, material changes in these amounts may occur in the future based on tax audits and changes in legislation.

Recent Accounting Pronouncements

In December 2011, the FASB issued ASU No. 2011

ITEM 7A. Q UANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET
RISKS

Commodity Risk

The Company’s major market risk exposure is in the pricing applicable to its oil and gas production. Realized pricing is primarily driven by the prevailing worldwide price for crude oil and spot prices applicable to natural gas production. Historically, prices receiv ed for oil and gas production have
been volatile and unpredictable and price volatility is expected to continue. Monthly oil price realizations

range d from a low of $ 76.04 per barrel to a high of $ 99.59 per barrel during 20 1 2 . Gas prices realizations

ran ged from monthly low of $ 2.26 per Mcf to a monthly high of $ 6.84 per Mcf during the same period.

In order to help mitigate commodity price risk, the Company has entered into a long term fixed price contract for MMC gas sales. On August 27, 2009, the Company entered into a five

- year fixed price gas sales contract with Atmos Energy Marketing, LLC, (“AEM”) in Houston, Texas, a nonregulated unit of Atmos Energy Corporation (NYSE: ATO) for the sale of the methane component of landfill gas

pro duced by MMC at the Carter Valley Landfill. The agreement provides for the sale of up to 600 MMBtu per day. The contract is effective beginning with September 2009 gas production and ends July

1 The credit facility maturity date of January 27, 201 5 is based on the March 6 , 201 3 amendment to the credit agreement50 31, 2014. The agreed contract price of over $6 per MMBtu wa s a premium to the then current five

- year strip price for natural gas on the NYMEX futures market.

In addition, during 2010, 2011, and 2012, the Company participated in derivative agreement s on a specified number of barrels of oil of its production. On J uly 28, 2009, the Company entered into a two

year agreement on crude oil pricing applicable to a specified number of barrels of oil that then constituted approximately two

- thirds of the Company’s daily production. Due to increased production levels, as we ll as a drop in the specified monthly barrels from 9,500 to 7,375 in 2011, th e number of barrels subject to this agreement constituted less than half of the Company’s average daily production at July 31 , 2011.

This “costless collar” agreement was effecti ve August 1, 2009 through July 31, 2011 and had a $60.00 per barrel floor and $81.50 per barrel cap on a volume of 9,500 barrels per month during the period from August 1, 2009 through December 31, 2010, and 7,375 barrels per month from January 1,
2011 thr ough July 31, 2011. The prices referenced in this agreement were WTI NYMEX. While the agreement was based on WTI NYMEX prices, the Company receives a price based on Kansas Common plus bonus, which results in a price approximately $7 per barrel less than cu rrent WTI NYMEX prices.

Under the “costless collar” agreement, no payment was made or received by the Company, as long as the settlement price was between the floor price and cap price (“within the collar”). However, if the settlement price was above the cap, the Company was required to pay the counterparty an amount equal to the excess of the settlement price over the cap times the monthly volumes hedged. If the settlement price was below the floor, the counterparty was required to pay the Company the de ficit of the settlement price below the floor times the monthly volumes hedged. As of August 1 2011, the “costless collar” agreement had expired.

On June 27, 2011 the Company entered into an agreement with Cargill Incorporated (“Cargill”)

, for the period from August 1, 2011 through December 31, 2012. The agreement provides to the Company a $65 per barrel floor on a stated quantity of 10,000 barrels per month, which is approximately half of the Company’s current production of oil. If the average price fal ls below $65 per barrel, then Cargill will pay to the Company the difference between $65 and the lower average price for 10,000 barrels per month in each month during when such lower average prices occur. However, unlike the “costless collar”
arrangement, the Company will not have a price cap on any portion of its production volumes. The cost of the Cargill agreement to the Company , which was paid on June 27, 2011, was $2.20 per barrel per month or a total of $374,000 for the entire period of the agreemen t. This agreement ended on December 31, 2012.

These agreements were primarily intended to help maintain and stabilize cash flow from operations if lower oil prices return.

Interest Rate Risk

At December 31, 20 1 2 , the Company had debt outstanding of approximately $ 1 0

. 3 million including, as of that date, $ 1 0.1 million owed on its credit facility with F&M Bank. The interest rate on the credit facility is variable at a rate equal to the greater of prime rate plus 0.25%

, or 5.25% per annu m

. The Company’s remaining debt of $ 0. 2 million has fixed interest rates ranging from 3.9 % to 7 .25%.51 As a result, the Company annual interest cost in 20 1 2 fluctuated based on shor t

- term interest rates on approximately 9 8 % of its total debt outstanding at December 31, 20 1 2

. During 20 1 2 , the Company paid approximately $0. 7 million of interest on the F&M Bank line of credit. The impact on interest expense and the Company’s c ash flows of a 10 % increase in the interest rate on the F&M Bank credit facility would be approximately $ 0. 05 million assuming borrowed amount s un d er the credit facility remained at the same amount owed as of December 31, 20 1 2 . The Company did not have any open derivative contracts relating to interest rates at D ecember 31, 20 1 2

.

Forward

- Looking Statements and Risk

Certain statements in this Report, including statements of the future plans, objectives, and expected performance of the Company, are forward

- looking statements that are dependent upon certain

events, risks and uncertainties that may be outside the Company’s control, and which would cause actual results to differ materially from those anticipated. Some of these include, but are not limited to, the market prices of oil and gas, economic and competitive conditions, inflation rates, legislative and regulatory changes, financial market conditions, political and economic uncertainties of foreign governments, future business decisions, and other uncertainties, all of which are difficult to predict.

There are numerous uncertainties inherent in projecting future rates of production and the timing of development expenditures. The total amount or timing of actual future production may vary significantly from estimates. The drilling of exploratory wells can involve significant risks, including those related to timing, success rates and cost overruns. Lease and rig availability, complex geology and
other factors can also affect these risks. Additionally, fluctuations in oil and gas prices, or a prolonge d period of low prices, may substantially adversely affect the Company ’s financial position, results of operations and cash flows.

ITEM 9 A

. C ONTROLS AND PROCEDURES

The Company’s Chief Executive Officer and Chief Financial Officer, and other members of management team have evaluated the effectiveness of the Company’s disclosure controls and procedures52 (as defined in Exchange Act Rules 13a

- 15(e) and 15d

- 15(e)). Based on such evalu ation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures, as of the end of the period covered by this Report, were adequate and effective to provide reasonable assurance t hat information required to be disclosed by the Company in reports that is files or submits under the Exchange Act, is recorded, processed, summarized and reported, within the
time periods specified in the SEC’s rules and forms.

The effectiveness of a sys tem of disclosure controls and procedures is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the soundness of internal controls, and fraud. Due to s uch inherent limitations, there can be no assurance that any system of disclosure controls and procedures will be successful in preventing all errors or fraud, or in making all material information known in a timely manner to the appropriate levels of mana gement.

Managements Annual Report on Internal Control O ver Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a

- 15(f) and 15d

- 15(f) promulgated under the Securities Exchange Act of 1934 . Internal control over financial reporting re fers to the process designed by , or under the supervision of the Company’s Chief Executive Officer and Chief Financial Officer, and effected by the Company ’s Board of Directors, management and other personnel, to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial

statem ents for external purposes in accordance with generally accepted accounting princi ples, and
includes those policies and procedures that:

• Pertain to the maintenance o f records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the Company’s assets;

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures a re being made only in accordance with authorizations of the Company’s management and directors; and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the
C ompany’s financial statements.

Because of it s inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness into future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, the Company’s management conducted an evaluation of the effectiveness of the Company internal control over financial reporting as of December 31, 2012

.5 3 In making this assessment, the Company’s management used the criteria set forth in the framework in
“Internal Control

- Integrated

- Framework” issued by the Committee of Sponsoring O rganizations of the Treadway Commission (“COSO”). Based on the evaluation conducted under the framework in “Internal
Control

- Integrated Framework,” issued by COSO the Company’s management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2012

.
This annual report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our registered public acco unting firm pursuant to rules of the Securities and Exchange Commission that permit the C ompany to provide only management’s report in this annual report.

Changes in Internal Control Over Financial Reporting

As part of a continuing effort to improve th e Co mpany’s business processes, m anagement is evaluating its internal controls and may update certain controls to accommodate any modifications to its business processes or accounting procedures. There have been no other changes to the Company’s system
of internal control over financial reporting during the year ended December 31, 201 2 that have materially affected, or are reasonably likely to materially affect, the Company’s system of controls over financial reporting.

Compensation and Stock Option Comm ittee

The members of the Compensation/Stock Option Committee in Fiscal 201 2 were Matthew K. Behrent and Hughree F. Brooks with Mr. Brooks acting as Chairman. Messrs. Behrent and Brooks meet the current independence standards established by the NYSE MKT R ules.

The Board of Directors has adopted a charter for the Compensation/Stock Option Committee which is available at the Company’s internet website, www.tengasco.com

.

4 Mr. Rugen's 16 0,000 unexercisable share options will vest a t the rate of 80,000 share options per year on 9/27/2013, and 9/27/2014.63 The Compensation/Stock Option Committee’s functions, in conjunction with the Board of Directors, are to provide recommendations with respect to general and specific compensation policies and practices of the Company for directors, officers and other employees of the Company. The Compe nsation/Stock Option Committee expects to periodically review the approach to executive compensation and to make changes as competitive conditions and other circumstances warrant and will seek to ensure the Company's compensation philosophy is consistent w ith the Company's best interests and is properly implemented. The Committee determines or recommends to the Board of Directors for determination the specific compensation of the Company’s Chief Executive Officer and all of the Company’s other officers. Alt hough the Committee may seek the input of the Company’s Chief Executive Officer in determining the compensation of the Company’s other executive officers, the Chief Executive Officer may not be present during the voting or deliberations with respect to his compensation. The Committee may not delegate any of its responsibilities unless it is to a subcommittee formed by the Committee, but only if such subcommittee consists entirely of directors who meet the independence requirements of the NYSE MKT Rules.

T he Compensation/Stock Option Committee is also charged with administering the Tengasco, Inc. Stock Incentive Plan (the “Stock Incentive Plan”). The Compensation/Stock Option Committee has complete discretionary authority with respect to the awarding of op tions and Stock Appreciation Rights (“SARs”), under the Stock Incentive Plan, including, but not limited to, determining the individuals who shall receive options and SARs; the times when they shall receive them; whether an option shall be an
incentive or a non

- qualified stock option; whether an SAR shall be granted separately, in tandem with or in addition to an option; the number of shares to be subject to each option and SAR; the term of each option and SAR; the date each option and SAR shall become exer cisable; whether an option or SAR shall be exercisable in whole, in part or in installments and the terms relating to such installments; the exercise price of each option and the base price of each SAR; the form of payment of the exercise price; the form

o f payment by the Company upon the exercise of an SAR; whether to restrict the sale or other disposition of the shares of common stock acquired upon the exercise of an option or SAR; to subject the exercise of all or any portion of an option or SAR to the f ulfillment of a contingency, and to determine whether such contingencies have been met; with the consent of the person receiving such option or SAR, to cancel or modify an option or SAR, provided such option or SAR as modified would be permitted to be gran ted on such date under the terms of the Stock Incentive Plan; and to make all other determinations necessary or advisable for administering the Plan.

The Compensation/Stock Option Committee met seven (7) times in Fiscal 201 2 . The Committee
has the author ity to retain a compensation consultant or other advisors to assist it in the evaluation of compensation and has the sole authority to approve the fees and other terms of retention of such
consultants and advisors and to terminate their services.

Compensa tion of Directors

The Board of Directors has resolved to compensate members of the Board of Directors for attendance at meetings at the rate of $250 per day, together with direct out

- of

- pocket expenses incurred in attendance at the meetings, including travel. The Directors, however, have waived such fees due to them as of this date for prior meetings.64 Members of the Board of Directors may also be requested to perform consulting or other professional services for the Company from time t o time, although at this time no such arrangements are in place. The Board of Directors has reserved to itself the right to review all directors' claims for compensation on an ad hoc basis.

Board members currently receive fees from the Company for their services as director. They may also from time to time be granted stock options under the Tengasco, Inc. Stock Incentive Plan. A separate plan to issue cash and/or shares of stock to independent directors for service on the Board and
various committees of the Board of Directors was authorized by the Board of Directors and approved by the Company ’ s shareholders. A copy of the Plan is posted at the Company ’ s website at www.tengasco.com. No award was made to any independent director under this plan in Fiscal 2012.

### 1. Description of Business and Significant Accounting Policies

Tengasco, Inc

. is a Delaware corporation (“Tengasco” or the “Company”).

The Company is in the business of explor ation and production of oil and natural gas. The Company’s primary area of oil exploration and production is in Kansas. The Company’s primary area of
natural gas exploration an d production is the Swan Creek F ield in Tennessee.

The Company’s wholly

- owned subsidiary, Tengasco Pipeline Corporation (“TPC”)

, owns and operates a 65 mile intrastate pipeline which it constructed to transport natural gas from the Company’s Swan Creek Field to customers in Kingsport, Tennessee.

The Compa ny’s wholly

- owned subsidiary, Manufactur ed Methane Corporation (“MMC”) operates treatment and delivery facilities using the latest developments in available treatment technologies for the extraction of methane gas from nonconventional sources for delivery through the nations existing natural gas pipeline system, including the Company’s TPC pipeline system in Tennessee for eventual sale to natural gas customers.

Principles of Consolidation

The accompanying consolidated financial statements are presented in accordance with accepted accounting principles generally accepted in the United States (“U.S. GAAP”) . The consolidated financial statements include the accounts of the Company, and its wholly

- owned subsidiaries after elimination of all significant int ercompany transactions and balances.

Use of Estimates

The accompanying consolidated financial statements are prepared in conformity with U.S. GAAP which require management to make estimates and assumptions that affect the reported amounts of assets
and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include reserve quantities and estimated future cash flows associated with proved reserves, which si gnificantly impact depletion expense and potential impairments of oil and natural gas properties, income taxes and the valuation of deferred tax assets, stock

based compensation and commitments and contingencies. We analyze our estimates based on historic al experience and various other assumptions that we believe to be reasonable. While we believe that our estimates and assumptions used in preparation of the consolidated financial statements are appropriate,
actual results could differ from those estimates

.

Revenue Recognition

Revenues are recognized based on actual volumes of oil , natural gas , methane gas, and electricity sold to purchasers at a fixed or determinable price, when delivery has occurred and title has transferred, and collectability is reasonably assured. Crude oil is stored and at the time of delivery to the

- 13 purchasers, revenues are recognized. Natural gas meters are placed at the customer’s location and usage
is billed each month. There were no material natural gas imbalances at December 31, 201 2 or 2011

. Methane gas and electricity sales meters are located at the tailgate of the Company’s Met hane Facility and
sales are billed each month.

Cash and Cash Equivalents

Cash and cash equivalents include temporary cash investments with a maturity of ninety days or less at date of purchase. The Company has elected to enter into a sweep account arrangement allowing excess cash balances to be used to temporarily pay down the credit facility, thereby, reducing overall
interest cost.

Restricted Cash

As security required by Tennessee oil and g as regulations, the Company placed $120,500 in a Certificate of Deposit to cover future asset retirement obligations for the Company’s Tennessee wells. At December 31, 2012 and 2011, this amount was recorded in the Consolidated Balance Sheets under

“Restr icted cash”.

In addition, during the 4 th quarter of 2012, the Company place d $386,000 as collateral for a bond to appeal a civil penalty related to issuance of an “Incidence of Non

- Compliance” by the Bureau of Ocean Energy Management (“ BOEM ”) concerning one of the Hoactzin wells operated by the Company pursuant to the Management Agreement

. At December 31, 2012, this amount was recorded in the Consolidated
Balance Sheets under “Restricted cash”. ( S ee Note 9

Inv entory

Inventory consists of crude oil in tanks and is carried at lower of cost or market value. The cost component of the oil inventory is calculated using the average per barrel cost which includes production costs and taxes, allocated general and ad ministrative costs, and allocated interest cost. The market component is calculated using the average December oil sales price for the Company’s Kansas properties.

I n addition, the Company also carried equipment and materials to be used in its Kansas operation and is
carried at the lower of cost or market value. The cost component of the equipment and materials inventory represents the original cost paid for the equipment and materials. The market component is
based on estimated sales value fo r similar equipment and materials at the end of each year. At December 31, 2012 and 2011 , inventory consisted of the following (in thousands):

- 14 Oil and Gas Properties

The Company follows the full cost method of accounting for oil and gas property acquisition, exploration, and development activities. Under this method, all cost s incurred in connection with acquisition, exploration and development of oil and gas reserves are capitalized. Capitalized costs include lease acquisitions, seismic related costs

, certain internal exploration costs, drilling, completion, and estimated asset retirement costs. The capi talized costs of oil and gas properties, plus estimated future development costs relating to proved reserves and estimated asset retirement costs, which are not already included net of estimated salvage value, are amortized on the unit

- of

- production method based on total proved reserves. The Company has determined its reserves based upon reserve reports provided by
LaRoche Petroleum Consultants Ltd. in 2012, 20 1 1 , 20 10 , and 200 9 . The costs of unproved properties are excluded from amortization until the prop erties are evaluated, subject to an annual assessment of whether impairment has occurred. The Company ha d $0.45 7 million and $0.268 million in unevaluated properties as of December 31, 2012 and 20 1 1 , respectively . Proceeds from the sale of oil and gas pr operties are accounted for as reductions to capitalized costs unless such sales cause a significant change in the relationship between costs and the estimated value of proved reserves, in which case a gain or loss is recognized.

At the end of each report ing period, the Company performs a “ceiling test” on the value of the net capitalized cost of oil and gas properties. This test compares the net capitalized cost (capitalized cost of oil and gas properties, net of accumulated depreciation, depletion and am ortization and related deferred income taxes) to the present value of estimated future net revenues from oil and gas properties using an average price (arithmetic average of the beginning of month prices for the prior 12 months) and current
cost discounted at 10% plus cost of properties not being amortized and the lower of cost or estimated fair value of unproven properties included in the cost being amortized (ceiling)

Asset Retirement Obligation

An asset retirement obligation associated with the retirement of a tangible long

- lived asset is recognized as a liability in the period incurred, with an associated increase in the carrying amount of the related long

- lived asset, our oil and natural gas properties. The cost of the tangible asset, including the asset retirement cost, is depleted over the useful life of the asset. The asset retirement obligation is recorded at its estimated fair value, measured by reference to the expected future cash outflows require d to satisfy the retirement obligation discounted at our credit

- adjusted risk

- free interest rate. Accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. Accretion expense is recorded as a “Produc tion costs and taxes” in the Consolidated Statements of Operations. If the estimated future cost of the asset retirement obligation changes, an adjustment is recorded to both the asset retirement obligation and the long

- lived asset. Revisions to estimated asset retirement obligations can result from changes in retirement cost estimates, revisions to estimated
inflation rates and changes in the estimated timing of abandonment.F

- 15 Pipeline Facilities

The pipeline was placed into service in 2001 . The pipeline is being depreciated over its estimated useful life of 30 years

. The Company reviews the carrying value of the pipeline for impairment whenever events and circumstances indicate that the carrying value of an asset may
not be recover able from the estimated future cash flows expected to result from its use and eventual disposition. In cases where undiscounted expected future cash flows are less than the carrying value, an impairment loss is recognized equal to an amount by which the ca rrying value exceeds the fair value of assets. The factors considered by management in performing this assessment include current operating results, trends, and prospects, as well as the effects of obsolescence, demand, competition, and other economic fact ors. During 2010 and 2012, there were indicators the pipeline may be impaired and the Company performed an assessment of the carrying value as of December 31, 2010 and December 31, 2012 based on expected future cash
flows. The assessment s resulted in the Company recording an impairment of approximately $5.0

million or $3. 3 million net of tax for the year ended December 31, 2010 and $5.2 million or $ 3. 4
million net of tax for the year ended December 31, 2012

. At December 31, 2011 management
determined ther e were no indicators of impairment, therefore, there is no impairment charge for the year ended December 31, 2011. The Company’s pipeline facilities are classified as an asset held for sale the related operations are classified as discontinued operations i n the accompanying
financial statements

. ( See Note 7

. Assets Held for Sale and Discontinued Operations )

Manufactured Methane Facilities

The methane facilities were placed into service on April 1, 2009. The methane facilities are being depreciated ov er an estimated useful life of 32 years and 9 months beginning at the time it was placed in service. This useful life is based on the estimated landfil l closure date of
December 2041

. (See Note 5

. Methane Project)

In June 2012, the Company received a payment in the amount of approximately $1.0 million from the United States Department of the Treasury for a cash payment in lieu of tax credits relating to the methane facilities. The payment to the Company was authorized under
Section 1603 of Division B of the American Recovery and Reinvestment Act of 2009. The grant amount was calculated pursuant to provisions applicable to a “landfill gas project,” defined in this statute as a project generating electricity from landfill gas. The Company may not take
investme nt tax credits for this facility as a result of accepting the cash payment, and is subject to annual reporting of the status of the project and recapture of all or a portion of the payment in the event the project were to be assigned to an ineligible nonpr ofit or governmental entity, during the five year period following the date of the award. The Company does not anticipate that the payment will be subject to recapture. Pursuant to the terms of the implementing federal regulations, the cash payment award ed is not treated as taxable income, but does reduce the taxable basis of the project by half of the grant amount. However, the book carrying amount of the property was reduced by the full amount of the payment.F

- 16 Other Property and Equi pment

Other property and equipment is carried at cost. The Company provides for depreciation of other property and equipment using the straight

- line method over the estimated useful lives of the assets which range from two to seven years. Net gains or losses on other property and equipment disposed of are included in operating income in the period in which the transaction

occurs. (See Note 6

. Other Property and Equipment)

Stock

- Based Compensation

The Company records stock

- based compensation to employees based on the estimated
fair value of the award at grant date . We recognize expense on a straight line basis over the requisite service period

. For stock

- based compensation that vests immediately, the Company recognizes the entire expense in the quarter in which the stock

- based compensation is granted. The Company recorded compensation expense of $ 0.05 million in 2012

, $ 0.2 million in 2011 and $ 0.1 million in 2010

.

Accounts Receivable

Accounts receivable consist of uncollateralized joint interest owner obligations due
within 30 days of the invoice date

, uncollateralized accrued revenues due under normal trade terms, generally requiring payment within 30 days of production , and other miscellaneous
receivables . No interest is charged on past

- du e balances. Payments made on accounts receivable are applied to the earliest unpaid items. We review accounts receivable periodically and reduce the carrying amount by a valuation allowance that reflects our best estimate of the amount that may not be c ollectible. No such allowance was considered necessary at December 31, 2012 or 2011

. At December 31, 2012 and 2011, accounts receivable consisted of the following (in thousands):

December 31,

2012 2011

Revenue $ 1,517 $ 1,412

Joint i nterest 65 112

Other 26 55

Total accounts receivable $ 1,608 $ 1,579

Income Taxes

Income taxes are reported in accordance with U.S. GAAP, which requires the establishment of deferred tax accounts for all temporary differences between the financial reporting and tax bases of assets and liabilities, using currently enacted federal and sta te income tax rates. In addition, deferred tax accounts must be adjusted to reflect new rates if enacted into
law. Management routinely assesses the ability to realize our deferred tax assets and reduces such assets by a valuation allowance if it is more likely than not that some portion or all of the
deferred tax assets will not be recognized.F

- 17 At December 31, 2012 , federal net operating loss carryforwards amounted to approximately $ 21.8 million which expire between 2019 and 2031 . The total deferred tax asset

was $ 9.4 million and $ 10.2 million at December 31, 2012 and 2011 , respectively

.

Realization of deferred tax assets is contingent on the generation of future taxable income. As a result, management considers whether it is mo re likely than not that all or a portion of such assets will be realized during periods when they are available, and if not, management provides a valuation allowance for amounts not likely to be recovered.

Management periodically evaluates tax reportin g methods to determine if any uncertain tax positions exist that would require the establishment of a loss contingency. A loss contingency would be recognized if it were probable that a liability has been incurred as of the date of the
financial statements and the amount of the loss can be reasonably estimated.

The amount recognized is subject to estimates and management’s judgment with respect to the likely outcome of each uncertain tax position. The amount that is ultimately incurred for an

in dividual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount recognized.

Although management considers our valuation allowance and loss contingency as of December 31, 2012 and 2011 adequate, material ch anges in these amounts may occur in the future based on tax audits and changes in legislation.

Concentration of Credit Risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash a nd accounts receivable. Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed federally insured limits. We have never experienced any losses related to these balances.

The Company’s primary business activ ities include oil and gas sales to a limited number of customers in the states of Kansas and Tennessee. The related trade receivables subject the Company to a concentration of credit risk.

The Company sells a majority of its crude oil primarily to one cu stomer in Tennessee and
two customers in Kansas. Additionally, t he Company presently sells all gas from the Swan Creek
Field and the Methane Facility to one customer

. In addition, the Company sell s the electricity generated at the Methane Facility to a local utility. Although management believes that customers could be replaced in the ordinary course of business, if the present customers were to discontinue business with the Company, it may have a significant adverse effect on the Company’s projected results of operations.F

Discontinued Operations

During 2012, the Company committed to a plan to sell the Swan Creek and Pipeline

assets. At December 31, 201 2, the Company was in the process of negotiating th is sale and on March 1, 2013, the Company entered into an agreement to sell the Company’s Swan Creek and Pipeline assets for $1.5 million. Final closing of this transaction is contingent upon customary

du e diligence as well as certain regulatory and easement holder approvals. T he Company has
elected to classif y the Pipeline assets as “Non

- current assets held for sale” in the Consolidated Balance Sheets for the years ended December 31, 2012 and 2011. The related results of operations have been classified as “Net loss from discontinued operations in the Consolida ted Statements of Operations for the years ended December 31, 2012, 2011 , and 2010. The related cash flows have been classified as “Net cash (used in) operating activities

– discontinued operations”, “Net cash (used in) investing activities

– discontinued operations”, and Net cash (used in) financing activities

– discontinued operations”. As the Swan Creek assets represent only a small portion of the Company’s full cost pool, these asset s will remain in oil and gas properties and related operations and wi ll continue to be classified in continuing operations. Unless otherwise indicated, the information in these notes relate to the Company’s continuing operations. Information related to the assets held for sale and discontinued operations is included
in “No te 7 . Assets Held for Sale and Discontinued Operations”.

2. Recent Accounting Pronouncements

In December 2011, the FASB issued ASU No. 2011

On September 17, 2007, the Company entered into a drilling program with Hoactzin Partners, L.P. (“Hoactzin”) for ten wells consisting of approximately three wildcat wells and seven developmental wells to be drilled on the Company’s Kansas Properties (the “Ten Well Program”). Peter E. Salas, the Chairman of the Board of Directors of the Company, is the controlling person of Hoactzin. He is a lso the sole shareholder and controlling person of Dolphin Management, Inc.

, the general partner of Dolphin Offshore Partners, L.P., which is the Company’s largest shareholder.

Under the terms of the Ten Well Program, Hoactzin paid the Company $0.4 milli on for each well drilled in the Ten Well Program completed as a producing well and $0.25 million for

each well that was non

- productive. The terms of the Ten Well Program also provide that Hoactzin will receive all the working interest in the ten wells in t he Program, but will pay an initial fee to the Company of 25% of its working interest revenues net of operating expenses. This is referred to as a management fee but, as defined, is in the nature of a net profits interest. The fee paid to the Company by Hoactzin will increase to 85% when and if net revenues received by Hoactzin reach an agreed payout point of approximately 1.35 times Hoactzin’s purchase price (the “Payout Point”) for its interest in the Ten Well Program.

In March 2008, the Company drilled and completed the tenth and final well in the Ten Well Program. Of the ten wells drilled, nine were completed as oil producers and are curr ently producing approximately 3 6 barrels per day in total. Hoactzin paid a total of $3.85 million (the

“Purch ase Price”) for its interest in the Ten Well Program resulting in the Payout Point being determined as $5.2 million. The amount paid by Hoactzin for its interest in the Program wells exceeded the Company’s actual drilling costs of approximately $2.8 milli on for the ten wells by more than $1 million.

U nder the terms of the Company’s agreement with Hoactzin, reaching the Payout Point may be accelerated by operation of a second agreement by which Hoactzin will apply 75% of the net profits it may receive from a methane extraction project discussed below developed by the Company’s wholly

- owned subsidiary, Manufactured Methane Corporation (“MMC”), to the Payout Point.

On September 17, 2007, Hoactzin, simultaneously with subscribing to participate in the

Ten W ell Program, pursuant to the second agreement referred to above with the Company was conveyed a 75% net profits interest in the methane extraction project developed by MMC at the Carter Valley landfill owned and operated by Republic Services in Church Hill , Tennessee (the "Methane Project"). Net profits, if any

, from the Project received by Hoactzin will be applied towards the determination of the Payout Point (as defined above) for the Ten Well Program.

Through December 31, 201 2 , no payments have been made to Hoactzin for its 75% net profits interest in the Methane Project, because no net profits have been generated.F

- 21 The method of calculation of the net profits interest takes into account specific costs and expenses as well as gross revenues for the project. As a result of the startup costs and ongoing operating expenses, no net profits

, as defined in the agreement

, have been generated from project startup in April, 2009 through December 31 , 201 2 for payment to Hoactzin under the net profits interest conveyed. When the Payout Point is reached from either the revenues from the wells
drilled in the Ten Well Program or Hoactzin’s share of the net profits from the Methane Project or a combination thereof, Hoactzin’s net profits in terest in the Methane Project will decrease to a 7.5% net profits interest.

As of December 31, 20 12 , net revenues received by Hoactzin from the Ten Well Program totaled $ 4.6 million which leaves a balance of $ 0.6 million until the Payout Point is reached

. On December 18, 2007, the Company entered into a Management Agreement with Hoactzin. On that same date, the Company also entered into an agreement with Charles Patrick McInturff employing him as a Vice

- President of the Company. Pursuant to the Managem ent Agreement with Hoactzin, Mr. McInturff’s duties while he is employed as Vice

- President of the Company will include the management on behalf of Hoactzin of its working interest in certain oil and gas properties owned by Hoactzin and located in the onsho re Texas Gulf Coast, and offshore Texas
and offshore Louisiana.

As consideration for the Company entering into the Management Agreement, Hoactzin agreed that it would be responsible to reimburse the Company for the payment of one

- half of Mr. McInturff’s salary, as well as certain other benefits he receives during his employment by the Company. In further consideration for the Company’s agreement to enter into the Mana gement Agreement, Hoactzin granted to the Company an option to participate in up to a 15% working interest on a dollar for dollar cost basis in any new drilling or workover activities undertaken on Hoactzin’s managed properties during the term of the Manag ement Agreement. The term of the Management Agreement ends on the earlier of the date Hoactzin sells its interest in its managed properties or five years. The Management Agreement terminated on December 18, 2012 . As of the date of this Report, the Compa ny is assisting Hoactzin with becoming operator of record of these wells and transferring the corresponding bonding liability from the Company to Hoactzin.

T he Company has entered into a transition agreement with Hoactzin whereby Hoactzin and its controlling member are indemnifying Tengasco for any costs or liabilities incurred by Tengasco resulting from such assistance, or the fact that Tengasco is still the operator of record on certain
of these wells.

During the course of the Management Agreeme nt, t he Company became the operator of certain properties owned by Hoactzin. The Company obtained from IndemCo, over time, bonds in the face amount of approximately $10.7 million for the purpose of covering plugging and abandonment obligations for Hoactzi n’s operated properties located in federal offshore waters in favor of the Bureau of Ocean Energy Management ( “ BOEM ” )

, as well as certain private parties. On October 12, 2012, the BOEM terminated $1.1 million of these bonds leaving a balance of approximat ely $9.6 million at December 31, 2012.F

- 22 In connection with the issuance of these bonds the Company entered into a Payment and Indemnity Agreement with IndemCo whereby the Company guarantees payment of any bonding

li abilities incurred by IndemCo. Dolphin Direct Equity Partners, LP co

- signed the Payment and Indemnity Agreement, thereby becoming jointly and severally liable with the Company for the obligations to IndemCo. Hoactzin has provided $6.6 million in cash to IndemCo as collateral for
these potential obligations. Dolphin Direct Equity Partners is a private equity fund controlled by
Peter E. Salas that h a s a significant economic interest in Hoactzin.

As operator, the Company routinely contracted in its name for goods and services with vendors in connection with its operation of the Hoactzin properties. In practice, Hoactzin directly paid these invoices for goods and services that were contracted in the Company’s name. During late 2009 and early 2010, Hoactzin undertook several si gnificant operations, for which the Company contracted in the ordinary course. As a result of the operations performed in late 2009 and early 2010, Hoactzin currently has significant past due balances to several vendors, a portion
of which are included on the Company’s balance sheet. Payables related to these past due and ongoing operations remained outstanding at the end of 2012 and 2011 in the amount of $ 0.325 million and $ 0.265 million respectively. T he Company has recorded the Hoactzin

- related payabl es and the corresponding receivable from Hoactzin as of December 31

, 2012 and 2011 in its Consolidated Balance Sheets under “Accounts payable

– other” and “Accounts receivable

– related party”. During the quarter s ended September 30, 2012 and December 31, 2012 , Hoactzin
ha d not made payments to reduce these past due balances. Based on these circumstances, the Company has elected to establish an allowance in the amount of $0.2 57 million for the balance outstanding at December 31 , 2012 less $0.068 million paid by Hoactzin in early 2013 . This
allowance was recorded in the Company’s Consolidated Balance Sheets under “Accounts
receivable

– related party” and in its Consolidated Statements of Operations in “General and
administrative”. No Teng asco funds have been advanced by Tengasco to pay any obligations of Hoactzin. No borrowing capability of Tengasco has been used by the Company in connection with its obligations under the Management Agreement

, except for those funds used to

collateralize the appeal bond with RLI Insurance Company (see Note 9 Commitments and Contingencies)

The bank credit facility payment is based on a maturity date of January 27, 2015.

At December 31, 2012 , the Company had a revolving credit facility with F&M Bank & Trust Company (“F&M Bank”). Under the credit facility, loans and letters of credit are availableF

- 25 to the Company on a revolving basis in an amount outstandin g not to exceed the lesser of $4 0 million or the Company’s borrowing base in effect from time t o time. As of December 31, 2012, the Company’s borrowing base was $21.5 million. The borrowing base was reduced to $20.5 million with the March 6, 2013 amendment to the credit agreement. The credit facility 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 credit facility includes certain

covenants with which the Company is required to comply. These covenants include leverage, interest coverage, minimum liquidity, and general and administrative coverage ratios. T he Company is in compliance with all covenants

.
On March 14, 2012, the Company’s senior credit facility with F&M Bank after F&M Bank’s semiannual review of the Company’s then owned produc ing properties was amended to
increase the Company’s borrowing base from $20 million to $23 million and extend the term of the facility to January 27, 2014. The interest rate remained the greater of prime plus 0.25% or 5.25% per annum. The Company’s inte rest rate at December 31, 2012 was 5.25%.

On September 12, 2012, the Company’s senior credit facility with F&M Bank after F&M Bank’s semiannual review of the Company’s then owned producing properties was amended to decrease the Company’s borrowing base from $23 million to $21.5 million. The term of the facility and interest rate remained unchanged.

On January 31, 2013, the Company’s senior credit facility with F&M Bank was amended to revise the “Change in Control” definition. No other changes we re made to the credit facility.

On March 6, 2013 , the Company’s senior credit facility with F&M Bank after F&M Bank’s semiannual review of the Company’s then owned producing properties was amended to

. Commitments and Contingencies

The Company is a party to lawsuits in the ordinary course of its business. The Company
does not believe that it is probable that the outcome of any individual action will have a material adverse effect, or that it is likely that adverse outcomes of individually insignificant actions will be significant enough, in number or magnitude, to have in the a ggregate a material adverse effect
on its financial statements. On March 1, 2010, the Company entered into a lease for office space in Knoxville, T ennessee . The term of the lease is 41 months (five of which are free) and expires on July 31, 201 3. The pay ment on this lease was $7,284 per month through December 2011 andF

- 26 is $7,294 per month for the remainder of the lease

. Future non

- cancellable commitments related to this lease total approximately $51,000 due in 2013.

Office rent expense for each of the three years ended December 31, 2012

, 2011

, and 2010 was $0.1 million

.

The Company as designated operator was administratively issued an “Incidence of Non

Compliance” by BOEM concerning one of the Hoactzin wells operated by the Company pursuant to the Management Agreement . This action calls for payment of a civil penalty of $386,000 for the late filing of certain reports in 2011 by a contractor on the facility. The Company has filed an appeal of this action in order to attempt to significantly reduce the civil penalty. This appeal required a fully collateralized appeal bond to stay payment of the obligation until the appeal is
determined. On November 1, 2012, t he Company posted and collateralized this bond wi th RLI Insurance Company. If the bond was not posted, the appeal would be administratively denied and the order to the Company as operator to pay the $386,000 penalty would be final. While the Company believes it will ultimately prevail in the appeal pro cess, it is reasonably possible to expect that the Company may be required to pay a portion of this penalty. The Company estimates the range of this possible payment to be between zero and $386,000.



### 10 . Fair Value Measurements

FASB ASC 820, “Fair Val ue Measurements and Disclosures”, establishes a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority

to u nadjusted quoted prices in active markers for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under FASB ASC 820 are described as fo llows:

Level 1

– Observable inputs, such as unadjusted quoted prices in active markets, for substantially
identical assets and liabilities.

Level 2

– Observable inputs other than quoted prices within Level 1 for similar assets and
liabilities. These include quoted prices for similar assets and liabilities in active markets, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. If the ass et or liability has a specified or contractual term, the input must be observable for substantially the full term of the asset or liability.

Level 3

– Unobservable inputs that are supported by little or no market activity, generally requiring a significant amount of judgment by management. The assets or liabilities fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximi ze the use of observable inputs and minimize the use of unobservable inputs. Following is a description of the valuation methodologies used for assets measured at fair value.F

- 27 The methods described above may produce a fair value calcula tion that may not be indicative of net realizable value or reflective of future fair values. Further, although the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or a ssumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting
date. The Company’s commodity derivative instruments are recorded at fair value on a recurring basis in our balance sheet with changes in fair value recorded in our income statement. The following table sets forth by level, within the fair value hierarchy, the Company’s assets and
liabilities at fair value on a recurring basis as of December 31, 2012 and December 31, 2 0 11. During 2012 and 2011, there were no changes in the fair value level classification . ( in thousands )

The fair value of the Company’s commodity derivative instruments are estimated using a pricing model which has various inputs including forward price curves, volatilities

, interest rates and contract terms. Contract terms related to the Company’s commodity derivative instruments
are defined in footnote 1 2 Derivatives.

Upon completion of wells, the Company records an asset retirement obligation at fair value using Level 3 assumptions.

Nonfinancial assets and liabilities are measured at fair value on a nonrecurring basis upon impairment

. Derivatives

On July 28, 2009, the Company entered into a two

- year agreement on crude oil pricing

. This “costless collar” agreement was effective from August 1, 2009 through July 31, 2011 and had a $60.00 per barrel floor and $81.50 per barrel cap on a volume of 9,500 barrels per month during the period from August 1, 2009 through December 31, 2010, and 7,375 barrels per month from January 1, 2011 through July 31, 2011. The prices referenced in this agreement were WTI NYMEX. While the agreement was based on WTI NYMEX prices, the Company receives a price based on Kansas Common plus bonus, which results in a price approximately $7 per barrel less than current WTI NYMEX prices. As of August 1 2011, the “costless collar” agreement had expired.

On June 27, 2011 the Company entered into an ag reement with Cargill, Incorporated for the period from August 1, 2011 through December 31, 2012 (“Cargill Agreement”). The agreement provides to the Company a $65 per barrel floor on a stated quantity of 10,000 barrels per month, which is approximately ha lf of the Company’s current production of oil. If the average price falls below $65 per barrel, then Cargill will pay to the Company the difference between $65 and the lower average price for 10,000 barrels per month in each month during when such lower a verage prices occur. However, unlike the “costless collar” arrangement, the Company will not have a price cap on any portion of its production volumes. The cost to the Company was $2.20 per barrel per month or a total of $374,000 for the entire period of the agreement. This cost was paid by the Company on June 27, 2011. These agreements were primarily intended to help maintain and stabilize cash flow from operations if lower oil prices return.

As of December 31 , 2011, the C ompany’s open forward posit ions were as follows (fair value is
based on meth odology described in footnote 10 Fair Value Measurement):F

The Company records changes in the unrealized derivative asset or liability as a “Gain (loss) on derivatives” in the Consolidated Statements of Operations. The Company recorded unrealized gains of $ 0.14 mi llion , $0.45 million, and $0.63 million during 2012 , 2011, and 2010, respectively.

During 2011, the Company made settlement payments related to the “costless collar” of $0.86 million. During 2010, the Company made settlement payments of $0.13 million. These realized losses were recorded as a “Gain (loss) on derivatives” in the Consolidated Statements of Operation. During 2012 , the Company made no settlement payments

. Stock Options

In October 2000, the Company approved a Stock Incentive Plan which was effective for a

ten

- year period commencing on October 25, 2000 and end ed on October 24, 2010. The aggregate
number of shares of Common Stock as to which options and S tock Appreciation Rights may be

gra nted to participants under the original P lan was not to exceed 7,000,000. The most recent amendment to the Plan increasing the number of shares that may be issued under the Plan by 3,500,000 shares and extending the Plan for another ten years was approved by t he Company’s Board of Directors on February 1, 2008 and approved by the Company’s shareholders at the Annual Meeting of Stockholders held on June 2, 2008. Options are not transferable, are exercisable for 3 months after voluntary resignation from the Comp any , and terminate immediately upon involuntary termination from the Company . The purchase price of shares subject to this P lan shall be determined a t the time the options are granted, but are not permitted
to be less than 85% of the fair market value of such shares on the date of grant. Furthermore, a participant in the Plan may not, immediately prior to the grant of an Incentive Stock Option

, own stock in the Company representing more than ten percent of the total voting power of all classes of stock of the Company unless the per share option price specified by the Board for the Incentive Stock Options granted such a participant is at least 110% of the fair market value of the Company’s sto ck on the date of grant and such option, by its terms , is not exercisable after the expiration of 5 years from the date such stock option is granted.

The Company does not believe that any of its positions it has taken will not prevail on a more likely than not basis. As such no disclosure of such positions was deemed n ecessary. Management continuously estimates its ability to recognize a deferred

tax asset related to prior period net operating loss carry forwards based on its anticipation of the likely timing and adequacy of future net income. As of December 31, 2012

, the Company had available approximately $ 21.8 million of federal net operating loss carryforwards to offset future taxable income.

As of December 31, 2012, management using the “more likely that not” criteria for recognition determined that, upon sale of the Pipeline asset, the Company would not be able to utilize the state net operating loss carryforwards associated with TPC, and therefore has established an allowance for these state net operating loss carryforwards.

As of December 31, 2011

, managemen t using the “more likely than not” criteria for recognition determined that increases in current projections of taxable income were sufficient that the valuation allowance was no longer necessary, therefore, the $1.7 million valuation allowance was removed

.

During the year ended December 31, 20 1 0

, m anagement , using the “more likely than not” criteria for recognition, elected to recognize a deferred tax asset of $ 1.1 million. The recognition of the deferred

tax asset i n 20 10 relates to net operating loss carryforwards , impairment of pipeline in 2010, and will provide a better matching of income tax expense with taxable income in future periods.

As of December 31, 2012 , the Compa ny had net operating loss carry forwards of approximately $ 21.8 million which will expire between 2019 and 2031 if not utilized. Our open tax years in clude all
