<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
preparation of financial statements in conformity with generally accepted accounting principles in the United States (&ldquo;GAAP&rdquo;)
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during
the reporting period. Significant estimates include oil and natural gas reserves that are used in the calculation of depreciation,
depletion, amortization and impairment of the carrying value of evaluated oil and natural gas properties; realizability of unevaluated
properties; production and commodity price estimates used to record accrued oil and natural gas sales receivables; futures prices
of commodities used in the valuation of commodity derivative contracts; valuation of warrant instruments; valuation of real estate
assets held for sale; and the cost of future asset retirement obligations. The Company evaluates its estimates on an on-going
basis and bases its estimates on historical experience and on various other assumptions the Company believes to be reasonable.
Due to inherent uncertainties, including the future prices of oil and natural gas, these estimates could change in the near term
and such changes could be material. In early March 2020, the NYMEX WTI crude oil price decreased significantly due to the COVID-19
pandemic and although it has recovered to pre-COVID-19 levels, it remained low for most of 2020. Lower oil and natural gas prices
not only decrease our revenues, but an extended decline in oil or gas prices may materially and adversely affect our future business,
financial position, cash flows, results of operations, liquidity, ability to finance planned capital expenditures and the oil
and natural gas reserves that we can economically produce.</FONT></P>

Company&rsquo;s results of operations and operating cash flows are affected by changes in market prices for crude oil and
natural gas. To manage a portion of its exposure to price volatility from producing crude oil, the Company entered into a
crude oil derivative swap contract during the three months ended March 31, 2021 to protect against price declines in future
periods. The Company does not designate commodity derivative contracts as cash flow hedges, and therefore the contract does
not qualify for hedge accounting. Changes in fair value of the swap contract are recorded in the condensed consolidated
statement of operations. The fair value of the swap contract is recorded as either an asset or a liability on the condensed
consolidated balance sheet.</FONT></P>

The New Horizon Acquisition gives the Company operated properties in its core area of operations. The New Horizon Properties consist
of nine gross wells (five net wells), and approximately 1,300 net acres located primarily in McKenzie and Divide Counties, North
Dakota, which are 100% held by production and average a 63% working interest.</FONT></P>

Company owns a 14-acre tract in Riverton, Wyoming with a two-story, 30,400 square foot office building and an additional 13-acre
parcel of land adjacent to the building. The building served as the Company&rsquo;s corporate headquarters until 2015 and is currently
being leased to government agencies and other non-affiliated companies. During the year ended December 31, 2020, the Company made
the decision to sell the land and building and began a process to determine the price at which it would list the property for
sale. The process included obtaining an appraisal, analyzing operating statements for the building, reviewing capitalization rates
and consulting a large national commercial real estate company. The Company determined that the realizable value of the building
and the building land was in the range of $700 thousand to $900 thousand and the realizable value of the additional land was in
the range of $250 thousand to $300 thousand. A special committee of the board of directors was formed to evaluate the sales process.
During 2020, the Company entered into an agreement with a large national commercial broker and a local broker in Riverton, Wyoming
to sell the building and the land. During the year ended December 31, 2020, the Company recognized a loss on the land and building
of $1,054 thousand. The following are estimated fair values and the estimated net proceeds relating to the real estate assets
held for sale at March 31, 2021 and December 31, 2020:</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
Company&rsquo;s revenues are primarily derived from its non-operated interest in the sales of oil and natural gas production.
The sales of oil and natural gas are made under contracts that operators of the wells have negotiated with third-party customers.
The Company receives payment from the sale of oil and natural gas production between one to three months after delivery. At the
end of each period when the performance obligation is satisfied, the variable consideration can be reasonably estimated and amounts
due from customers are accrued in oil and natural gas sales receivable in the consolidated balance sheets. Variances between the
Company&rsquo;s estimated revenue and actual payments are recorded in the month the payment is received; however, differences
have been and are insignificant. Accordingly, the variable consideration is not constrained. As a non-operator of its oil and
natural gas properties, the Company records its share of the revenues and expenses based upon the information provided by the
operators within the revenue statements.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
Company&rsquo;s oil and natural gas production is typically sold at delivery points to various purchasers under contract terms
that are common in the oil and natural gas industry. Regardless of the contract type, the terms of these contracts compensate
the well operators for the value of the oil and natural gas at specified prices, and then the well operators remit payment to
the Company for its share in the value of the oil and natural gas sold.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">During
2020, the Company acquired operated oil and gas producing properties (see Note 2, above). The Company sells its oil production
at the delivery point specified in the contract and collects an agreed-upon index price, net of pricing differentials. The purchaser
takes custody, title and risk of loss of the oil at the delivery point; therefore, control passes at the delivery point. The Company
recognizes revenue at the net price received when control transfers to the purchaser. Natural gas and natural gas liquid (&ldquo;NGL&rdquo;)
are sold at the lease location, which is generally when control of the natural gas and NGL transfers to the purchaser, and revenue
is recognized as the amount received from the purchaser.</FONT></P>

Company does not disclose the values of unsatisfied performance obligations under its contracts with customers as it applies the
practical exemption in accordance with Accounting Standards Codification (ASC) 606. The exemption applies to variable consideration
that is recognized as control of the product is transferred to the customer. Since each unit of product represents a separate
performance obligation, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to the remaining
performance obligations is not required.</FONT></P>

Company reports revenue as the gross amount received from the well operators before taking into account production taxes and transportation

were reported gross for the three months ended March 31, 2021 and 2020, as the gross amounts were known.</FONT></P>

the Company used $40.01 per barrel for oil and $2.16 per one million British Thermal Units (MMbtu) for natural gas (as further
adjusted for property, specific gravity, quality, local markets and distance from markets) to compute the future cash flows of
the Company&rsquo;s producing properties. The discount factor used was 10%.</FONT></P>

March 4, 2021, the Company closed a Debt Conversion Agreement (the &ldquo;Conversion Agreement&rdquo;) with APEG Energy II, L.P.(
&ldquo;APEG&rdquo;), which entity Patrick E. Duke, a former director of the Company, has shared voting power and shared investment
power over. The Conversion Agreement was related to a $375,000 related party secured note payable the Company borrowed from APEG
on September 24, 2020 (the &ldquo;Note&rdquo;). The Note accrued interest at 10% per annum and had a maturity date of September
24, 2021. The Note was secured by the Company&rsquo;s wholly-owned subsidiary, Energy One&rsquo;s oil and natural gas producing
properties. Under the terms of the Note, the Company may repay the Note prior to maturity, however, in the event of a prepayment
of the Note, the Company was required to pay APEG the amount of interest which would have accrued through maturity (at 10% per
annum). Pursuant to the Conversion Agreement, the Company converted the related party secured note payable of $375,000 and accrued
interest to the date of the Note&rsquo;s September 24, 2021 maturity of $37,500 by issuing 97,962 shares of unregistered common
stock with a value on the date of the Conversion Agreement of $438,000. The difference of $25,500 between the value of the shares
issued and the $412,500 amount of the Note and accrued interest through the date of maturity is recorded as interest expense,

Company&rsquo;s results of operations and cash flows are affected by changes in market prices for crude oil and natural gas. To
manage a portion of its exposure to price volatility from producing crude oil, the Company entered into a fixed-price swap commodity
derivative contract to protect against price declines in future periods on 100 barrels of crude oil per day from March 1 to December
31, 2021, at $61.90, based on the calendar month average of West Texas Intermediate Crude Oil (&ldquo;WTI&rdquo;). There are no
collateral requirements for the fixed-price swap derivative contract. The Company does not enter into derivative contracts for
speculative purposes. The Company has not elected to designate the fixed-price swap as a cash flow hedge; therefore, the instrument
does not qualify for hedge accounting. Accordingly, changes in the fair value of the fixed-price swap contract are recoded in
the unaudited condensed consolidated statements of operations and are included in cash flows from operating activities in the
condensed consolidated statement of cash flows.</FONT></P>

APEG initiated a shareholder derivative action in Colorado against Mr. Veltri due to his refusal to recognize the Board&rsquo;s

Company has asset retirement obligations (&ldquo;AROs&rdquo;) associated with the future plugging and abandonment of proved properties.
Initially, the fair value of a liability for an ARO is recorded in the period in which the ARO is incurred with a corresponding
increase in the carrying amount of the related asset. The liability is accreted to its present value each period and the capitalized
cost is depleted over the life of the related asset. If the liability is settled for an amount other than the recorded amount,
an adjustment to the full-cost pool is recognized. The Company had no assets that are restricted for the purpose of settling AROs.</FONT></P>

the fair value calculation for the ARO there are numerous assumptions and judgments, including the ultimate retirement cost, inflation
factors, credit-adjusted risk-free discount rates, timing of retirement and changes in legal, regulatory, environmental, and political
environments. To the extent future revisions to assumptions and judgments impact the present value of the existing ARO, a corresponding
adjustment is made to the oil and natural gas property balance.</FONT></P>

tax assets (&ldquo;DTAs&rdquo;) are recognized for the expected future tax consequences of temporary differences between the financial
reporting and tax basis of assets and liabilities and for operating losses and tax credit carry-forwards. We review our DTAs and
valuation allowance on a quarterly basis. As part of our review, we consider positive and negative evidence, including cumulative
results in recent years. Consistent with the position at March 31, 2021, the Company maintains a full valuation allowance recorded
against all DTAs. The Company, therefore, had no recorded DTAs as of March 31, 2021. We anticipate that we will continue to record
a valuation allowance against our DTAs in all jurisdictions until such time as we are able to determine that it is &ldquo;more-likely-than-not&rdquo;
that those DTAs will be realized.</FONT></P>

$8.9 million in net operating loss carryovers (after limitations). During the three months ended March 31, 2021 and year ended December
31, 2020, the Company issued approximately 1.3 million and 2.0 million additional shares of common stock, respectively in various transactions.
The Company is currently evaluating whether these issuances represented an ownership change that would have triggered a loss limitation
under Internal Revenue Code (&ldquo;I.R.C.&rdquo;) Section 382. However, since the Company maintains a valuation allowance against these
tax assets there is no impact to the condensed consolidated statement of operations for the three months ended March 31, 2021.</P>

net loss per common share is calculated by dividing net loss attributable to common shareholders by the weighted-average number
of common shares outstanding for the respective period. Diluted net loss per common share is calculated by dividing adjusted net
loss by the diluted weighted average number of common shares outstanding, which includes the effect of potentially dilutive securities.
Potentially dilutive securities for this calculation consist of stock options and warrants, which are measured using the treasury
stock method, the conversion feature of the Series A Preferred Stock prior to redemption, and unvested shares of restricted common
stock. When the Company recognizes a net loss, as was the case for the three months ended March 31, 2021 and 2020, all potentially
dilutive shares are anti-dilutive and are consequently excluded from the calculation of dilutive net loss per common share.</FONT></P>

Company&rsquo;s fair value measurements are estimated pursuant to a fair value hierarchy that requires us to maximize the use
of observable inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy is based upon
the transparency of inputs to the valuation of an asset or liability as of the measurement date, giving highest priority to quoted
prices in active markets (Level 1) and the lowest priority to unobservable data (Level 3). In some cases, the inputs used to measure
fair value might fall in different levels of the fair value hierarchy. The lowest level input that is significant to a fair value
measurement in its entirety determines the applicable level in the fair value hierarchy. Assessing the significance of a particular
input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability,
and may affect the valuation of the assets and liabilities and their placement within the hierarchy level. The three levels of
inputs that may be used to measure fair value are defined as:</FONT></P>

markets, or other observable inputs that can be corroborated by observable market data.</FONT></P>

value requires significant management judgment or estimation.</FONT></P>

warrants contain a dilutive issuance and other provisions that cause the warrants to be accounted for as a liability. Such warrant
instruments are initially recorded and valued as a Level 3 liability and are accounted for at fair value with changes in fair
value reported in earnings. There were no changes in the methodology to value the warrants. The Company worked with a third-party
valuation expert to estimate the value of the warrants at March 31, 2021 and December 31, 2020 using a Black Scholes model, with
the following observable and unobservable inputs:</FONT></P>

Energy Corp. - is a Wyoming corporation organized in 1966. We are an independent energy company focused on the acquisition and
development of oil and natural gas producing properties in the continental United States. Our business activities are currently
focused in South Texas, the Williston Basin in North Dakota, Lea County in New Mexico and Converse County in Wyoming.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">We
have historically explored for and produced oil and natural gas through a non-operator business model. As a non-operator, we rely
on our operating partners to propose, permit, drill, complete and produce oil and natural gas wells. Before a well is drilled,
the operator provides all oil and natural gas interest owners in the designated well the opportunity to participate in the drilling
and completion costs and revenues of the well on a pro-rata basis. Our operating partners also produce, transport, market and
account for all oil and natural gas production. With recent acquisitions in 2020 of New Horizon Resources, certain FieldPoint
Petroleum wells and certain wells in Liberty County, Texas we now operate a small portion of our production.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">In
early March 2020, there was an outbreak of a novel strain of coronavirus, which causes the infectious disease known as COVID-19,
which resulted in a drastic decline in global demand of certain mineral and energy products including crude oil. As a result of
the lower demand caused by the COVID-19 pandemic and the oversupply of crude oil, spot and future prices of crude oil fell to
historic lows during the second quarter of 2020, which remained depressed for the majority of 2020. Operators in North Dakota&rsquo;s
Williston Basin responded by significantly decreasing drilling and completion activity and shutting in or curtailing production
from a significant number of producing wells, all of which have since come back online. Operator&rsquo;s decisions on these matters
are changing rapidly and it is difficult to predict the future effects on the Company&rsquo;s business. Lower oil and natural
gas prices not only decrease our revenues, but an extended decline in oil or gas prices may materially and adversely affect our
future business, financial position, cash flows, results of operations, liquidity, ability to finance planned capital expenditures
and the oil and natural gas reserves that we can economically produce.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">Additionally,
the outbreak of COVID-19 and decreases in commodity prices resulting from oversupply, government-imposed travel restrictions,
and other constraints on economic activity have caused a significant decrease in the demand for oil and has created disruptions
and volatility in the global marketplace for oil and gas which began in the first quarter of 2020, and continued through most
of 2020, which negatively affected our results of operations and cash flows. While demand and commodity prices have recently recovered
and are back to pre-pandemic levels, our financial results may continue to be depressed in future quarters. The extent to which
the COVID-19 pandemic impacts our business going forward will depend on numerous evolving factors we cannot reliably predict,
including the duration and scope of the pandemic; governmental, business, and individuals&rsquo; actions in response to the pandemic;
the availability and efficacy of vaccines, and the willingness of individuals to obtain such vaccines; and the impact on economic
activity including the possibility of recession or financial market instability. These factors may adversely impact the supply
and demand for oil and gas and our ability to produce and transport oil and gas and perform operations at and on our properties.
This uncertainty also affects management&rsquo;s accounting estimates and assumptions, which could result in greater variability
in a variety of areas that depend on these estimates and assumptions, including investments, receivables, and forward-looking
guidance.</FONT></P>

July 2020, the Company received a request for arbitration from its former Chief Executive Officer, David Veltri claiming that
the Company breached his employment agreement. The Company intends to vigorously contest this matter and believes these claims
are without merit. The employment agreement requires that any disputes be submitted to binding arbitration. The Company has insurance
for these types of claims and has reported the request for arbitration to its insurance carrier. Through March 31, 2021, the Company
has incurred defence costs in this matter of $90 thousand and has accrued $10 thousand for future defence costs, representing
the Company&rsquo;s responsibility for costs under the insurance policy.</FONT></P>

February 2019 until August 2020, the Company was involved in litigation with its former Chief Executive Officer, David Veltri
and at the time its largest shareholder, APEG Energy II, L.P. (&ldquo;APEG II&rdquo;) and APEG II&rsquo;s general partner, APEG
Energy II, GP (together with APEG II, &ldquo;APEG&rdquo;). In addition, Patrick E. Duke, a former director of the Company, had
shared voting and shared investment power over APEG. The litigation arose as a result of a vote at the February 25, 2019 board
of directors meeting to terminate Mr. Veltri for using Company funds outside of his authority and for other reasons (the &ldquo;Texas
Litigation&rdquo;). In a separate lawsuit, APEG initiated a shareholder derivative action in Colorado against Mr. Veltri due to
his refusal to recognize the Board&rsquo;s decision to terminate him (the &ldquo;Colorado Litigation&rdquo;). The Company was
named as a nominal defendant in the Colorado Litigation. The Colorado litigation was dismissed in May 2020 and the Texas Litigation
was dismissed in August 2020. Through March 31, 2021, the Company had incurred legal costs of approximately $1.7 million related
to the litigation. On March 4, 2021, the Company issued 90,846 shares of unregistered common stock, which had a value on the date
of issuance of $406 thousand, to APEG in reimbursement of APEG&rsquo;s legal costs in the Colorado and Texas Litigation.</FONT></P>

statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these
estimates under different assumptions or conditions. A summary of our significant accounting policies is detailed in <I>Part II,

Company&rsquo;s results of operations and operating cash flows are affected by changes in market prices for crude oil and
natural gas. To manage a portion of our exposure to price volatility from producing crude oil, we entered into a crude oil
derivative swap contract during the three months ended March 31, 2021, to protect against price declines in future periods.
The Company does not designate commodity derivative contracts as a cash flow hedges and therefore the contract does not
qualify for hedge accounting. Changes in fair value of the swap contract are recorded in the condensed consolidated statement
of operations. The fair value of the swap contract is recorded as either an asset or a liability on the condensed
consolidated balance sheet.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
increase in our oil and gas revenue of $288 thousand for the three months ended March 31, 2021, as compared to the three
months ended March 31, 2020, was due to an increase in oil production of 8% and an increase in the realized price received
for our oil production of 23%. The increase in oil prices is primarily due to stronger demand for crude oil on a global basis
as the world recovers from government mandated lockdowns which began in mid-March 2020 in order to reduce the spread of the
COVID-19 pandemic. The increase in oil production volumes is primarily the result of the acquisitions of operated properties
we completed during 2020, and our efforts to return idle wells to production. During the three months ended March 31, 2021,
we produced 7,056 Bbls from operated properties acquired in 2020. These production increases were partially offset by
production declines from our South Texas wells drilled in late 2018 and early 2019.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">For
the three months ended March 31, 2021, we produced 25,905 BOE, or an average of 288 BOE per day, as compared to 27,204 BOE or
299 BOE per day during the comparable period in 2020; however, the production mix shifted to become more oil weighted in 2021,
due to the acquisition in 2020 of operated oil properties. During the three months ended March 31, 2021, our BOE production mix
was 84% oil and 16% natural gas compared to 75% oil and 25% gas in the comparable period of 2020. The gas production declines
are primarily coming from our South Texas region where we have experienced steep production declines from initial production rates
for wells drilled in late 2018 and 2019 as the wells have matured.</FONT></P>

in the value of our common stock during the period, which was partially offset by a decrease in the warrant liability due to the
exercise of warrants to purchase 50,000 shares of common stock (leaving warrants to purchase 50,000 shares of common stock outstanding),

own a 14-acre tract in Riverton, Wyoming with a two-story, 30,400 square foot office building and an additional 13-acre parcel
of land adjacent to the building. The building served as our corporate headquarters until 2015 and is currently being leased to
government agencies and other non-affiliated companies. During 2020, we made the decision to sell the land and building and began
a process to determine the price at which we would list the property for sale. The process included obtaining an appraisal, analysing
operating statements for the building, reviewing capitalization rates and consulting a large national commercial real estate company.
We determined the realizable value of the real estate assets was in the range of $950 thousand to $1.2 million. A special committee
of the board of directors was formed to evaluate the sales process and during 2020, we entered into an agreement with a large
national commercial broker and a local broker in Riverton, Wyoming to sell our real estate assets. We plan to sell the property
in 2021.</FONT></P>

material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there

31, 2020, filed with the SEC on March 26, 2021, in connection with our assessment of the effectiveness of our internal control
over financial reporting at the end of our last fiscal year, management identified the following material weaknesses in our internal
control over financial reporting as of December 31, 2020 and is in the process of remediating such material weaknesses as of March

Our financial condition as of March 31, 2021, and operating results for the three months ended March 31, 2021,&#13;are not necessarily indicative of the financial condition and results of operations that may be expected for any future interim period&#13;or for the year ending December 31, 2021.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Use of Estimates&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The preparation of financial statements in conformity&#13;with generally accepted accounting principles in the United States (&amp;#8220;GAAP&amp;#8221;) requires management to make estimates and assumptions&#13;that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial&#13;statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include oil and natural&#13;gas reserves that are used in the calculation of depreciation, depletion, amortization and impairment of the carrying value of evaluated&#13;oil and natural gas properties; realizability of unevaluated properties; production and commodity price estimates used to record accrued&#13;oil and natural gas sales receivables; futures prices of commodities used in the valuation of commodity derivative contracts; valuation&#13;of warrant instruments; valuation of real estate assets held for sale; and the cost of future asset retirement obligations. The Company&#13;evaluates its estimates on an on-going basis and bases its estimates on historical experience and on various other assumptions the Company&#13;believes to be reasonable. Due to inherent uncertainties, including the future prices of oil and natural gas, these estimates could change&#13;in the near term and such changes could be material. In early March 2020, the NYMEX WTI crude oil price decreased significantly due to&#13;the COVID-19 pandemic and although it has recovered to pre-COVID-19 levels, it remained low for most of 2020. Lower oil and natural gas&#13;prices not only decrease our revenues, but an extended decline in oil or gas prices may materially and adversely affect our future business,&#13;financial position, cash flows, results of operations, liquidity, ability to finance planned capital expenditures and the oil and natural&#13;gas reserves that we can economically produce.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Significant Accounting Policies&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&amp;#8217;s results of operations and operating&#13;cash flows are affected by changes in market prices for crude oil and natural gas. To manage a portion of its exposure to price volatility&#13;from producing crude oil, the Company entered into a crude oil derivative swap contract during the three months ended March 31, 2021 to&#13;protect against price declines in future periods. The Company does not designate commodity derivative contracts as cash flow hedges, and&#13;therefore the contract does not qualify for hedge accounting. Changes in fair value of the swap contract are recorded in the condensed&#13;consolidated statement of operations. The fair value of the swap contract is recorded as either an asset or a liability on the condensed&#13;consolidated balance sheet.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Principles of Consolidation&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The accompanying financial statements include the&#13;accounts of U.S. Energy Corp. and its wholly owned subsidiaries Energy One LLC (&amp;#8220;Energy One&amp;#8221;) and New Horizon Resources LLC&#13;(&amp;#8220;New Horizon&amp;#8221;).

The Company accounted for the acquisition of the New Horizon Properties as&#13;a business combination.

The New Horizon Acquisition gives the Company&#13;operated properties in its core area of operations. The New Horizon Properties consist of nine gross wells (five net wells), and approximately&#13;1,300 net acres located primarily in McKenzie and Divide Counties, North Dakota, which are 100% held by production and average a 63% working&#13;interest.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The properties were acquired from FieldPoint&#13;Petroleum Corporation (&amp;#8220;FieldPoint&amp;#8221;) pursuant to FieldPoint&amp;#8217;s Chapter 7 bankruptcy process (the &amp;#8220;FieldPoint Properties&amp;#8221;).&#13;The Company accounted for the acquisition of the FieldPoint Properties as an asset acquisition. The total amount paid for the FieldPoint&#13;Properties as of December 31, 2020, was $597 thousand, which includes the purchase price of $500 thousand and transaction costs of $97&#13;thousand, of which $29 thousand were paid via the issuance of 7,075 shares of the Company&amp;#8217;s common stock. The Company also recorded&#13;purchase price adjustments of $31 thousand for net revenues received, less operating expenses related to periods prior to the closing&#13;of the transaction. In addition, the Company recorded asset retirement obligations of $203 thousand for the assets acquired. Substantially&#13;all of the value of the acquired FieldPoint Properties consists of mature proved developed producing reserves.

The&#13;transaction closed on December 1, 2020 with an effective date of November 1, 2020. The assets include operated producing properties in&#13;Liberty County, Texas (the &amp;#8220;Liberty County Properties&amp;#8221;). The Liberty County Properties include 41 wells which have a 100%&#13;working interest and an average 86% net revenue interest and approximately 680 net acres located primarily in Liberty County, Texas which&#13;are 100% held by production. The Company issued 67,254 shares of its common stock, which at the closing price of $4.24 on the date of&#13;the closing of the PSA, were valued at $285 thousand, in consideration for the acquisition. The Company accounted for the acquisition&#13;of the Liberty County Properties as an asset acquisition. The total amount paid as of December 31, 2020, was $326 thousand including transaction&#13;costs of $41 thousand. In addition, the Company recorded asset retirement obligations of $192 thousand for the assets acquired. Substantially&#13;all of the value of the Liberty County Properties acquired consisted of mature proved developed producing reserves and proved developed&#13;non-producing reserves. Following is a summary of the amounts recorded for the assets acquired:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif;

The building served as the Company&amp;#8217;s corporate headquarters until 2015 and is currently being leased to government agencies&#13;and other non-affiliated companies. During the year ended December 31, 2020, the Company made the decision to sell the land and building&#13;and began a process to determine the price at which it would list the property for sale. The process included obtaining an appraisal,&#13;analyzing operating statements for the building, reviewing capitalization rates and consulting a large national commercial real estate&#13;company. The Company determined that the realizable value of the building and the building land was in the range of $700 thousand to $900&#13;thousand and the realizable value of the additional land was in the range of $250 thousand to $300 thousand. A special committee of the&#13;board of directors was formed to evaluate the sales process. During 2020, the Company entered into an agreement with a large national&#13;commercial broker and a local broker in Riverton, Wyoming to sell the building and the land. During the year ended December 31, 2020,&#13;the Company recognized a loss on the land and building of $1,054 thousand.

Duke, a former&#13;director of the Company, has shared voting power and shared investment power over. The Conversion Agreement was related to a $375,000&#13;related party secured note payable the Company borrowed from APEG on September 24, 2020 (the &amp;#8220;Note&amp;#8221;). The Note accrued interest&#13;at 10% per annum and had a maturity date of September 24, 2021. The Note was secured by the Company&amp;#8217;s wholly-owned subsidiary,&#13;Energy One&amp;#8217;s oil and natural gas producing properties. Under the terms of the Note, the Company may repay the Note prior to maturity,&#13;however, in the event of a prepayment of the Note, the Company was required to pay APEG the amount of interest which would have accrued&#13;through maturity (at 10% per annum). Pursuant to the Conversion Agreement, the Company converted the related party secured note payable&#13;of $375,000 and accrued interest to the date of the Note&amp;#8217;s September 24, 2021 maturity of $37,500 by issuing 97,962 shares of unregistered&#13;common stock with a value on the date of the Conversion Agreement of $438,000. The difference of $25,500 between the value of the shares&#13;issued and the $412,500 amount of the Note and accrued interest through the date of maturity is recorded as interest expense, net, in&#13;the condensed consolidated statements of operations.&lt;/p&gt;</us-gaap:DebtDisclosureTextBlock>

To manage a portion of its exposure to price volatility&#13;from producing crude oil, the Company entered into a fixed-price swap commodity derivative contract to protect against price declines&#13;in future periods on 100 barrels of crude oil per day from March 1 to December 31, 2021, at $61.90, based on the calendar month average&#13;of West Texas Intermediate Crude Oil (&amp;#8220;WTI&amp;#8221;). There are no collateral requirements for the fixed-price swap derivative contract.&#13;The Company does not enter into derivative contracts for speculative purposes. The Company has not elected to designate the fixed-price&#13;swap as a cash flow hedge; therefore, the instrument does not qualify for hedge accounting. Accordingly, changes in the fair value of&#13;the fixed-price swap contract are recoded in the unaudited condensed consolidated statements of operations and are included in cash flows&#13;from operating activities in the condensed consolidated statement of cash flows.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The Company intends&#13;to vigorously contest this matter and believes these claims are without merit. The employment agreement requires that any disputes be&#13;submitted to binding arbitration. The Company has insurance for these types of claims and has reported the request for arbitration to&#13;its insurance carrier. Through March 31, 2021, the Company has incurred defence costs in this matter of $90 thousand and has accrued $10&#13;thousand for future defence costs, representing the Company&amp;#8217;s responsibility for costs under the insurance policy.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;APEG II Litigation&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"&gt;From February 2019 until&#13;August 2020, the Company was involved in litigation with its former Chief Executive Officer, David Veltri and at the time its largest&#13;shareholder, APEG II and APEG II&amp;#8217;s general partner, APEG Energy II, GP (together with APEG II, &amp;#8220;APEG&amp;#8221;). In addition,&#13;Patrick E. Duke, a former director of the Company, had shared voting and shared investment power over APEG. The litigation arose as a&#13;result of a vote at the February 25, 2019 board of directors meeting to terminate Mr. Veltri for using Company funds outside of his authority&#13;and for other reasons (the &amp;#8220;Texas Litigation&amp;#8221;). In a separate lawsuit, APEG initiated a shareholder derivative action in&#13;Colorado against Mr. Veltri due to his refusal to recognize the Board&amp;#8217;s decision to terminate him (the &amp;#8220;Colorado Litigation&amp;#8221;).&#13;The Company was named as a nominal defendant in the Colorado Litigation. The Colorado litigation was dismissed in May 2020 and the Texas&#13;Litigation was dismissed in August 2020. Through March 31, 2021, the Company had incurred legal costs of approximately $1.7 million related&#13;to the litigation. On March 4, 2021, the Company issued 90,846 shares of unregistered common stock, which had a value on the date of&#13;issuance of $406 thousand, to APEG in reimbursement of APEG&amp;#8217;s legal costs in the Colorado and Texas Litigation.&lt;/p&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

The liquidation preference on the date of redemption was $3.6 million. The difference between the redemption&#13;price and the liquidation preference of the preferred stock was included as a reduction of the net loss available to common shareholders&#13;in the calculation of loss per share.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company had issued the 50,000 shares of Preferred&#13;Stock on February 12, 2016, to Mt. Emmons Mining Company (&amp;#8220;MEM&amp;#8221;), a subsidiary of Freeport McMoRan Inc., in connection with&#13;the disposition of the Company&amp;#8217;s mining segment, whereby MEM acquired the property and replaced the Company as permittee and operator&#13;of a water treatment plant (the &amp;#8220;Acquisition Agreement&amp;#8221;). The Preferred Stock was issued at $40 per share for an aggregate&#13;of $2 million. The Preferred Stock liquidation preference, initially $2 million, increased by quarterly dividends of 12.25% per annum&#13;(the &amp;#8220;Adjusted Liquidation Preference&amp;#8221;). At the option of the holder, each share of Preferred Stock initially could have&#13;been converted into 1.33 shares of the Company&amp;#8217;s $0.01 par value Common Stock (the &amp;#8220;Conversion Rate&amp;#8221;) for an aggregate&#13;of 66,667 shares. The Conversion Rate was subject to anti-dilution adjustments for stock splits, stock dividends and certain reorganization&#13;events and to price-based anti-dilution protections, subject to a price floor. At March 31, 2020, the aggregate number of shares of Common&#13;Stock issuable upon conversion was 79,334 shares, which was the maximum number of shares issuable upon conversion.&lt;/p&gt;</us-gaap:PreferredStockTextBlock>

Concurrently, the investors received warrants&#13;to purchase 100,000 shares of common stock of the Company at an exercise price of $20.05 per share, for a period of five years from the&#13;final closing date of June 21, 2017. The warrants include anti-dilution rights. The total net proceeds received by the Company were approximately&#13;$1.32 million. The fair value of the warrants upon issuance were $1.24 million, with the remaining $0.08 million being attributed to common&#13;stock. On September 29, 2020, the Company received proceeds of $565 thousand related to the exercise of warrants to purchase 50,000 shares&#13;of common stock. The warrants have been classified as liabilities due to features in the warrant agreement that give the warrant holder&#13;an option to require the Company to redeem the warrant at a calculated fair value in the event of a &amp;#8220;Fundamental Transaction,&amp;#8221;&#13;as defined in the warrant agreement. The fair value of the remaining warrants to purchase 50,000 shares of common stock was $115 thousand&#13;and $95 thousand at March 31, 2021 and December 31, 2020, respectively.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Pursuant to the original warrant agreement, as a result&#13;of common stock issuances at various prices, the warrant exercise price has been reduced from its original $20.50 exercise price to the&#13;floor price of $3.92, which is the exercise price of the warrants at March 31, 2021.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Stock Options&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;From time to time, the Company may grant stock options&#13;under its incentive plan covering shares of common stock to employees of the Company.

Diluted&#13;net loss per common share is calculated by dividing adjusted net loss by the diluted weighted average number of common shares outstanding,&#13;which includes the effect of potentially dilutive securities. Potentially dilutive securities for this calculation consist of stock options&#13;and warrants, which are measured using the treasury stock method, the conversion feature of the Series A Preferred Stock prior to redemption,&#13;and unvested shares of restricted common stock. When the Company recognizes a net loss, as was the case for the three months ended March&#13;31, 2021 and 2020, all potentially dilutive shares are anti-dilutive and are consequently excluded from the calculation of dilutive net&#13;loss per common share.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

Significant estimates include oil and natural&#13;gas reserves that are used in the calculation of depreciation, depletion, amortization and impairment of the carrying value of evaluated&#13;oil and natural gas properties; realizability of unevaluated properties; production and commodity price estimates used to record accrued&#13;oil and natural gas sales receivables; futures prices of commodities used in the valuation of commodity derivative contracts; valuation&#13;of warrant instruments; valuation of real estate assets held for sale; and the cost of future asset retirement obligations. The Company&#13;evaluates its estimates on an on-going basis and bases its estimates on historical experience and on various other assumptions the Company&#13;believes to be reasonable. Due to inherent uncertainties, including the future prices of oil and natural gas, these estimates could change&#13;in the near term and such changes could be material. In early March 2020, the NYMEX WTI crude oil price decreased significantly due to&#13;the COVID-19 pandemic and although it has recovered to pre-COVID-19 levels, it remained low for most of 2020. Lower oil and natural gas&#13;prices not only decrease our revenues, but an extended decline in oil or gas prices may materially and adversely affect our future business,&#13;financial position, cash flows, results of operations, liquidity, ability to finance planned capital expenditures and the oil and natural&#13;gas reserves that we can economically produce.&lt;/p&gt;</us-gaap:UseOfEstimates>

The Company&amp;#8217;s effective tax rate used to estimate income taxes on a current year-to-date&#13;basis is 0% for the three months ended March 31, 2021 and 2020.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Deferred tax assets (&amp;#8220;DTAs&amp;#8221;) are recognized&#13;for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities&#13;and for operating losses and tax credit carry-forwards. We review our DTAs and valuation allowance on a quarterly basis. As part of our&#13;review, we consider positive and negative evidence, including cumulative results in recent years. Consistent with the position at March&#13;31, 2021, the Company maintains a full valuation allowance recorded against all DTAs. The Company, therefore, had no recorded DTAs as&#13;of March 31, 2021. We anticipate that we will continue to record a valuation allowance against our DTAs in all jurisdictions until such&#13;time as we are able to determine that it is &amp;#8220;more-likely-than-not&amp;#8221; that those DTAs will be realized.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;At December 31, 2020, the Company had approximately&#13;$8.9 million in net operating loss carryovers (after limitations). During the three months ended March 31, 2021 and year ended December&#13;31, 2020, the Company issued approximately 1.3 million and 2.0 million additional shares of common stock, respectively in various transactions.&#13;The Company is currently evaluating whether these issuances represented an ownership change that would have triggered a loss limitation&#13;under Internal Revenue Code (&amp;#8220;I.R.C.&amp;#8221;) Section 382. However, since the Company maintains a valuation allowance against these&#13;tax assets there is no impact to the condensed consolidated statement of operations for the three months ended March 31, 2021.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company recognizes, measures, and discloses uncertain&#13;tax positions whereby tax positions must meet a &amp;#8220;more-likely-than-not&amp;#8221; threshold to be recognized.

The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability&#13;as of the measurement date, giving highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable&#13;data (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The lowest&#13;level input that is significant to a fair value measurement in its entirety determines the applicable level in the fair value hierarchy.&#13;Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors&#13;specific to the asset or liability, and may affect the valuation of the assets and liabilities and their placement within the hierarchy&#13;level. The three levels of inputs that may be used to measure fair value are defined as:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Level 1 - Quoted prices for identical assets and liabilities&#13;traded in active exchange markets.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Level 2 - Observable inputs other than Level 1 that&#13;are directly or indirectly observable for the asset or liability, including quoted prices for similar assets or liabilities in active&#13;markets, quoted prices for identical or similar assets or liabilities inactive markets, or other observable inputs that can be corroborated&#13;by observable market data.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Level 3 - Unobservable inputs supported by little&#13;or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or&#13;similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Warrant Valuation&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The warrants contain a dilutive issuance and other&#13;provisions that cause the warrants to be accounted for as a liability. Such warrant instruments are initially recorded and valued as a&#13;Level 3 liability and are accounted for at fair value with changes in fair value reported in earnings. There were no changes in the methodology&#13;to value the warrants. The Company worked with a third-party valuation expert to estimate the value of the warrants at March 31, 2021&#13;and December 31, 2020 using a Black Scholes model, with the following observable and unobservable inputs:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The fair value of the oil and gas properties is determined based upon estimated&#13;future discounted cash flow, a Level 3 input, using estimated production which we reasonably expect, and estimated prices adjusted for&#13;differentials. Unobservable inputs include estimated future oil and natural gas production, prices, operating and development costs, and&#13;a discount rate of 10%, all Level 3 inputs within the fair value hierarchy.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company evaluates the fair value on a non-recurring&#13;basis of its Riverton, Wyoming real estate assets when circumstances indicate that the value has been impaired. The change in the economic&#13;environment due to the COVID-19 pandemic and the property&amp;#8217;s remote location has caused a lack of relevant comparable sales to use&#13;as a basis for estimating fair value. At March 31, 2021, the Company estimated the fair value of the real estate based upon offers it&#13;had received for the real estate, the expected annual net operating income of the building, estimated capitalization rates for properties&#13;in rural areas and values for vacant land based on comparable sales, all Level 3 inputs within the fair value hierarchy.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

REVENUE RECOGNITION&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&amp;#8217;s revenues are primarily derived&#13;from its non-operated interest in the sales of oil and natural gas production. The sales of oil and natural gas are made under contracts&#13;that operators of the wells have negotiated with third-party customers. The Company receives payment from the sale of oil and natural&#13;gas production between one to three months after delivery. At the end of each period when the performance obligation is satisfied, the&#13;variable consideration can be reasonably estimated and amounts due from customers are accrued in oil and natural gas sales receivable&#13;in the consolidated balance sheets. Variances between the Company&amp;#8217;s estimated revenue and actual payments are recorded in the month&#13;the payment is received; however, differences have been and are insignificant. Accordingly, the variable consideration is not constrained.&#13;As a non-operator of its oil and natural gas properties, the Company records its share of the revenues and expenses based upon the information&#13;provided by the operators within the revenue statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&amp;#8217;s oil and natural gas production&#13;is typically sold at delivery points to various purchasers under contract terms that are common in the oil and natural gas industry. Regardless&#13;of the contract type, the terms of these contracts compensate the well operators for the value of the oil and natural gas at specified&#13;prices, and then the well operators remit payment to the Company for its share in the value of the oil and natural gas sold.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;During 2020, the Company acquired operated oil and&#13;gas producing properties (see Note 2, above). The Company sells its oil production at the delivery point specified in the contract and&#13;collects an agreed-upon index price, net of pricing differentials. The purchaser takes custody, title and risk of loss of the oil at the&#13;delivery point; therefore, control passes at the delivery point. The Company recognizes revenue at the net price received when control&#13;transfers to the purchaser. Natural gas and natural gas liquid (&amp;#8220;NGL&amp;#8221;) are sold at the lease location, which is generally&#13;when control of the natural gas and NGL transfers to the purchaser, and revenue is recognized as the amount received from the purchaser.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company does not disclose the values of unsatisfied&#13;performance obligations under its contracts with customers as it applies the practical exemption in accordance with Accounting Standards&#13;Codification (ASC) 606. The exemption applies to variable consideration that is recognized as control of the product is transferred to&#13;the customer. Since each unit of product represents a separate performance obligation, future volumes are wholly unsatisfied, and disclosure&#13;of the transaction price allocated to the remaining performance obligations is not required.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company reports revenue as the gross amount received&#13;from the well operators before taking into account production taxes and transportation costs. Production taxes are reported separately,&#13;and transportation costs are included in lease operating expense in the accompanying unaudited condensed consolidated statements of operations.&#13;The revenue and costs in the consolidated statements of operations were reported gross for the three months ended March 31, 2021 and 2020,&#13;as the gross amounts were known.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company disaggregates revenues from its share&#13;of revenue from the sale of oil and natural gas and liquids by state.

subsidiaries, Energy One LLC and New Horizon Resources, LLC, referred to as the &#8220;Company&#8221; in these Notes to Unaudited Condensed
Consolidated Financial Statements) was incorporated in the State of Wyoming on January 26, 1966. The Company&#8217;s principal business
activities are focused on the acquisition, exploration and development of oil and natural gas properties in the United States.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The accompanying unaudited condensed consolidated
financial statements are presented in accordance with U.S. generally accepted accounting principles (&#8220;GAAP&#8221;) and have been
prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the &#8220;SEC&#8221;) regarding
interim financial reporting. Accordingly, certain information and footnote disclosures required by GAAP for complete financial statements
have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, all adjustments (consisting
of normal recurring adjustments) considered necessary for a fair presentation of the consolidated financial statements have been included.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For further information, refer to the consolidated
financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with
the SEC on March 26, 2021. Our financial condition as of March 31, 2021, and operating results for the three months ended March 31, 2021,
are not necessarily indicative of the financial condition and results of operations that may be expected for any future interim period
or for the year ending December 31, 2021.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The preparation of financial statements in conformity
with generally accepted accounting principles in the United States (&#8220;GAAP&#8221;) requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include oil and natural
gas reserves that are used in the calculation of depreciation, depletion, amortization and impairment of the carrying value of evaluated
oil and natural gas properties; realizability of unevaluated properties; production and commodity price estimates used to record accrued
oil and natural gas sales receivables; futures prices of commodities used in the valuation of commodity derivative contracts; valuation
of warrant instruments; valuation of real estate assets held for sale; and the cost of future asset retirement obligations. The Company
evaluates its estimates on an on-going basis and bases its estimates on historical experience and on various other assumptions the Company
believes to be reasonable. Due to inherent uncertainties, including the future prices of oil and natural gas, these estimates could change
in the near term and such changes could be material. In early March 2020, the NYMEX WTI crude oil price decreased significantly due to
the COVID-19 pandemic and although it has recovered to pre-COVID-19 levels, it remained low for most of 2020. Lower oil and natural gas
prices not only decrease our revenues, but an extended decline in oil or gas prices may materially and adversely affect our future business,
financial position, cash flows, results of operations, liquidity, ability to finance planned capital expenditures and the oil and natural
gas reserves that we can economically produce.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s results of operations and operating
cash flows are affected by changes in market prices for crude oil and natural gas. To manage a portion of its exposure to price volatility
from producing crude oil, the Company entered into a crude oil derivative swap contract during the three months ended March 31, 2021 to
protect against price declines in future periods. The Company does not designate commodity derivative contracts as cash flow hedges, and
therefore the contract does not qualify for hedge accounting. Changes in fair value of the swap contract are recorded in the condensed
consolidated statement of operations. The fair value of the swap contract is recorded as either an asset or a liability on the condensed
consolidated balance sheet.</p>

in North Dakota (the &#8220;New Horizon Properties&#8221;). The Company accounted for the acquisition of the New Horizon Properties as
a business combination. The consideration paid at closing consisted of 59,498 shares of the Company&#8217;s restricted common stock, $150,000
in cash and the assumption of certain liabilities (the &#8220;New Horizon Acquisition&#8221;). The New Horizon Acquisition gives the Company

1,300 net acres located primarily in McKenzie and Divide Counties, North Dakota, which are 100% held by production and average a 63% working

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">For the three months ended
March 31, 2021, the Company recorded revenues of approximately $36 thousand, and lease operating and workover expenses of approximately
$21 thousand related to the New Horizon Properties. Assuming that the acquisition of the New Horizon properties had occurred on January
1, 2020, the Company would have recorded revenues of $32 thousand and expenses of $25 thousand for the three months ended March 31, 2020,
These results are not necessarily indicative of the results that would have occurred had the Company completed the acquisition on the
date indicated, or that will be attained in the future. Subsequent to the closing of the New Horizon Acquisition, the Company repaid the
outstanding liabilities assumed at closing.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">The Company owns a 14-acre
tract in Riverton, Wyoming with a two-story, 30,400 square foot office building and an additional 13-acre parcel of land adjacent to the
building. The building served as the Company&#8217;s corporate headquarters until 2015 and is currently being leased to government agencies
and other non-affiliated companies. During the year ended December 31, 2020, the Company made the decision to sell the land and building
and began a process to determine the price at which it would list the property for sale. The process included obtaining an appraisal,
analyzing operating statements for the building, reviewing capitalization rates and consulting a large national commercial real estate
company. The Company determined that the realizable value of the building and the building land was in the range of $700 thousand to $900
thousand and the realizable value of the additional land was in the range of $250 thousand to $300 thousand. A special committee of the
board of directors was formed to evaluate the sales process. During 2020, the Company entered into an agreement with a large national
commercial broker and a local broker in Riverton, Wyoming to sell the building and the land. During the year ended December 31, 2020,
the Company recognized a loss on the land and building of $1,054 thousand. The following are estimated fair values and the estimated net
proceeds relating to the real estate assets held for sale at March 31, 2021 and December 31, 2020:</p>

<td class="text"><p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"><b>4. REVENUE RECOGNITION</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s revenues are primarily derived
from its non-operated interest in the sales of oil and natural gas production. The sales of oil and natural gas are made under contracts
that operators of the wells have negotiated with third-party customers. The Company receives payment from the sale of oil and natural
gas production between one to three months after delivery. At the end of each period when the performance obligation is satisfied, the
variable consideration can be reasonably estimated and amounts due from customers are accrued in oil and natural gas sales receivable
in the consolidated balance sheets. Variances between the Company&#8217;s estimated revenue and actual payments are recorded in the month
the payment is received; however, differences have been and are insignificant. Accordingly, the variable consideration is not constrained.
As a non-operator of its oil and natural gas properties, the Company records its share of the revenues and expenses based upon the information
provided by the operators within the revenue statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s oil and natural gas production
is typically sold at delivery points to various purchasers under contract terms that are common in the oil and natural gas industry. Regardless
of the contract type, the terms of these contracts compensate the well operators for the value of the oil and natural gas at specified
prices, and then the well operators remit payment to the Company for its share in the value of the oil and natural gas sold.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">During 2020, the Company acquired operated oil and
gas producing properties (see Note 2, above). The Company sells its oil production at the delivery point specified in the contract and
collects an agreed-upon index price, net of pricing differentials. The purchaser takes custody, title and risk of loss of the oil at the
delivery point; therefore, control passes at the delivery point. The Company recognizes revenue at the net price received when control
transfers to the purchaser. Natural gas and natural gas liquid (&#8220;NGL&#8221;) are sold at the lease location, which is generally
when control of the natural gas and NGL transfers to the purchaser, and revenue is recognized as the amount received from the purchaser.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company does not disclose the values of unsatisfied
performance obligations under its contracts with customers as it applies the practical exemption in accordance with Accounting Standards
Codification (ASC) 606. The exemption applies to variable consideration that is recognized as control of the product is transferred to
the customer. Since each unit of product represents a separate performance obligation, future volumes are wholly unsatisfied, and disclosure
of the transaction price allocated to the remaining performance obligations is not required.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company reports revenue as the gross amount received
from the well operators before taking into account production taxes and transportation costs. Production taxes are reported separately,
and transportation costs are included in lease operating expense in the accompanying unaudited condensed consolidated statements of operations.
The revenue and costs in the consolidated statements of operations were reported gross for the three months ended March 31, 2021 and 2020,
as the gross amounts were known.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company disaggregates revenues from its share
of revenue from the sale of oil and natural gas and liquids by state. The Company&#8217;s revenues in its North Dakota, Texas and other
states for the three months ended March 31, 2021 and 2020, are presented in the following table:</p>

In the calculation of the ceiling test as of March 31, 2021, the Company used $40.01 per barrel for oil and $2.16 per one million British
Thermal Units (MMbtu) for natural gas (as further adjusted for property, specific gravity, quality, local markets and distance from markets)
to compute the future cash flows of the Company&#8217;s producing properties. The discount factor used was 10%.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On March 4, 2021, the Company closed a Debt Conversion
Agreement (the &#8220;Conversion Agreement&#8221;) with APEG Energy II, L.P.( &#8220;APEG&#8221;), which entity Patrick E. Duke, a former
director of the Company, has shared voting power and shared investment power over. The Conversion Agreement was related to a $375,000
related party secured note payable the Company borrowed from APEG on September 24, 2020 (the &#8220;Note&#8221;). The Note accrued interest
at 10% per annum and had a maturity date of September 24, 2021. The Note was secured by the Company&#8217;s wholly-owned subsidiary,
Energy One&#8217;s oil and natural gas producing properties. Under the terms of the Note, the Company may repay the Note prior to maturity,
however, in the event of a prepayment of the Note, the Company was required to pay APEG the amount of interest which would have accrued
through maturity (at 10% per annum). Pursuant to the Conversion Agreement, the Company converted the related party secured note payable
of $375,000 and accrued interest to the date of the Note&#8217;s September 24, 2021 maturity of $37,500 by issuing 97,962 shares of unregistered
common stock with a value on the date of the Conversion Agreement of $438,000. The difference of $25,500 between the value of the shares
issued and the $412,500 amount of the Note and accrued interest through the date of maturity is recorded as interest expense, net, in
the condensed consolidated statements of operations.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s results of operations and cash
flows are affected by changes in market prices for crude oil and natural gas. To manage a portion of its exposure to price volatility
from producing crude oil, the Company entered into a fixed-price swap commodity derivative contract to protect against price declines
in future periods on 100 barrels of crude oil per day from March 1 to December 31, 2021, at $61.90, based on the calendar month average
of West Texas Intermediate Crude Oil (&#8220;WTI&#8221;). There are no collateral requirements for the fixed-price swap derivative contract.
The Company does not enter into derivative contracts for speculative purposes. The Company has not elected to designate the fixed-price
swap as a cash flow hedge; therefore, the instrument does not qualify for hedge accounting. Accordingly, changes in the fair value of
the fixed-price swap contract are recoded in the unaudited condensed consolidated statements of operations and are included in cash flows
from operating activities in the condensed consolidated statement of cash flows.</p>

from its former Chief Executive Officer, David Veltri claiming that the Company breached his employment agreement. The Company intends
to vigorously contest this matter and believes these claims are without merit. The employment agreement requires that any disputes be
submitted to binding arbitration. The Company has insurance for these types of claims and has reported the request for arbitration to
its insurance carrier. Through March 31, 2021, the Company has incurred defence costs in this matter of $90 thousand and has accrued $10
thousand for future defence costs, representing the Company&#8217;s responsibility for costs under the insurance policy.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">From February 2019 until
August 2020, the Company was involved in litigation with its former Chief Executive Officer, David Veltri and at the time its largest
shareholder, APEG II and APEG II&#8217;s general partner, APEG Energy II, GP (together with APEG II, &#8220;APEG&#8221;). In addition,
Patrick E. Duke, a former director of the Company, had shared voting and shared investment power over APEG. The litigation arose as a
result of a vote at the February 25, 2019 board of directors meeting to terminate Mr. Veltri for using Company funds outside of his authority
and for other reasons (the &#8220;Texas Litigation&#8221;). In a separate lawsuit, APEG initiated a shareholder derivative action in
Colorado against Mr. Veltri due to his refusal to recognize the Board&#8217;s decision to terminate him (the &#8220;Colorado Litigation&#8221;).
The Company was named as a nominal defendant in the Colorado Litigation. The Colorado litigation was dismissed in May 2020 and the Texas
Litigation was dismissed in August 2020. Through March 31, 2021, the Company had incurred legal costs of approximately $1.7 million related
to the litigation. On March 4, 2021, the Company issued 90,846 shares of unregistered common stock, which had a value on the date of
issuance of $406 thousand, to APEG in reimbursement of APEG&#8217;s legal costs in the Colorado and Texas Litigation.</p><span></span>

million and issuing 328,000 shares of its common stock, which at the date of the redemption had a value of $3.68 per share for a total
redemption price of $3.2 million. The liquidation preference on the date of redemption was $3.6 million. The difference between the redemption
price and the liquidation preference of the preferred stock was included as a reduction of the net loss available to common shareholders
in the calculation of loss per share.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company had issued the 50,000 shares of Preferred

the disposition of the Company&#8217;s mining segment, whereby MEM acquired the property and replaced the Company as permittee and operator
of a water treatment plant (the &#8220;Acquisition Agreement&#8221;). The Preferred Stock was issued at $40 per share for an aggregate
of $2 million. The Preferred Stock liquidation preference, initially $2 million, increased by quarterly dividends of 12.25% per annum
(the &#8220;Adjusted Liquidation Preference&#8221;). At the option of the holder, each share of Preferred Stock initially could have
been converted into 1.33 shares of the Company&#8217;s $0.01 par value Common Stock (the &#8220;Conversion Rate&#8221;) for an aggregate
of 66,667 shares. The Conversion Rate was subject to anti-dilution adjustments for stock splits, stock dividends and certain reorganization
events and to price-based anti-dilution protections, subject to a price floor. At March 31, 2020, the aggregate number of shares of Common
Stock issuable upon conversion was 79,334 shares, which was the maximum number of shares issuable upon conversion.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In December 2016, the Company completed a registered
direct offering of 100,000 shares of common stock at a net gross price of $15.00 per share. Concurrently, the investors received warrants
to purchase 100,000 shares of common stock of the Company at an exercise price of $20.05 per share, for a period of five years from the
final closing date of June 21, 2017. The warrants include anti-dilution rights. The total net proceeds received by the Company were approximately
$1.32 million. The fair value of the warrants upon issuance were $1.24 million, with the remaining $0.08 million being attributed to common
stock. On September 29, 2020, the Company received proceeds of $565 thousand related to the exercise of warrants to purchase 50,000 shares
of common stock. The warrants have been classified as liabilities due to features in the warrant agreement that give the warrant holder
an option to require the Company to redeem the warrant at a calculated fair value in the event of a &#8220;Fundamental Transaction,&#8221;
as defined in the warrant agreement. The fair value of the remaining warrants to purchase 50,000 shares of common stock was $115 thousand
and $95 thousand at March 31, 2021 and December 31, 2020, respectively.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Pursuant to the original warrant agreement, as a result
of common stock issuances at various prices, the warrant exercise price has been reduced from its original $20.50 exercise price to the
floor price of $3.92, which is the exercise price of the warrants at March 31, 2021.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">From time to time, the Company may grant stock options
under its incentive plan covering shares of common stock to employees of the Company. Stock options, when exercised, are settled through
the payment of the exercise price in exchange for new shares of stock underlying the option. These awards typically expire ten years from
the grant date.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has asset retirement obligations (&#8220;AROs&#8221;)
associated with the future plugging and abandonment of proved properties. Initially, the fair value of a liability for an ARO is recorded
in the period in which the ARO is incurred with a corresponding increase in the carrying amount of the related asset. The liability is
accreted to its present value each period and the capitalized cost is depleted over the life of the related asset. If the liability is
settled for an amount other than the recorded amount, an adjustment to the full-cost pool is recognized. The Company had no assets that
are restricted for the purpose of settling AROs.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In the fair value calculation for the ARO there are
numerous assumptions and judgments, including the ultimate retirement cost, inflation factors, credit-adjusted risk-free discount rates,
timing of retirement and changes in legal, regulatory, environmental, and political environments. To the extent future revisions to assumptions
and judgments impact the present value of the existing ARO, a corresponding adjustment is made to the oil and natural gas property balance.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The following is a reconciliation of the changes in

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Deferred tax assets (&#8220;DTAs&#8221;) are recognized
for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities
and for operating losses and tax credit carry-forwards. We review our DTAs and valuation allowance on a quarterly basis. As part of our
review, we consider positive and negative evidence, including cumulative results in recent years. Consistent with the position at March
31, 2021, the Company maintains a full valuation allowance recorded against all DTAs. The Company, therefore, had no recorded DTAs as
of March 31, 2021. We anticipate that we will continue to record a valuation allowance against our DTAs in all jurisdictions until such
time as we are able to determine that it is &#8220;more-likely-than-not&#8221; that those DTAs will be realized.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">At December 31, 2020, the Company had approximately
$8.9 million in net operating loss carryovers (after limitations). During the three months ended March 31, 2021 and year ended December
31, 2020, the Company issued approximately 1.3 million and 2.0 million additional shares of common stock, respectively in various transactions.
The Company is currently evaluating whether these issuances represented an ownership change that would have triggered a loss limitation
under Internal Revenue Code (&#8220;I.R.C.&#8221;) Section 382. However, since the Company maintains a valuation allowance against these
tax assets there is no impact to the condensed consolidated statement of operations for the three months ended March 31, 2021.</p>

tax positions whereby tax positions must meet a &#8220;more-likely-than-not&#8221; threshold to be recognized. During the three months

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Basic net loss per common share is calculated by dividing
net loss attributable to common shareholders by the weighted-average number of common shares outstanding for the respective period. Diluted
net loss per common share is calculated by dividing adjusted net loss by the diluted weighted average number of common shares outstanding,
which includes the effect of potentially dilutive securities. Potentially dilutive securities for this calculation consist of stock options
and warrants, which are measured using the treasury stock method, the conversion feature of the Series A Preferred Stock prior to redemption,
and unvested shares of restricted common stock. When the Company recognizes a net loss, as was the case for the three months ended March
31, 2021 and 2020, all potentially dilutive shares are anti-dilutive and are consequently excluded from the calculation of dilutive net
loss per common share.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The following table sets forth the calculation of
basic and diluted net loss per share for the three months ended March 31, 2021 and 2020:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s fair value measurements are estimated
pursuant to a fair value hierarchy that requires us to maximize the use of observable inputs and minimize the use of unobservable inputs
when measuring fair value. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability
as of the measurement date, giving highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable
data (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The lowest
level input that is significant to a fair value measurement in its entirety determines the applicable level in the fair value hierarchy.
Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors
specific to the asset or liability, and may affect the valuation of the assets and liabilities and their placement within the hierarchy
level. The three levels of inputs that may be used to measure fair value are defined as:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Level 1 - Quoted prices for identical assets and liabilities
traded in active exchange markets.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Level 2 - Observable inputs other than Level 1 that
are directly or indirectly observable for the asset or liability, including quoted prices for similar assets or liabilities in active
markets, quoted prices for identical or similar assets or liabilities inactive markets, or other observable inputs that can be corroborated
by observable market data.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Level 3 - Unobservable inputs supported by little
or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or
similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The warrants contain a dilutive issuance and other
provisions that cause the warrants to be accounted for as a liability. Such warrant instruments are initially recorded and valued as a
Level 3 liability and are accounted for at fair value with changes in fair value reported in earnings. There were no changes in the methodology
to value the warrants. The Company worked with a third-party valuation expert to estimate the value of the warrants at March 31, 2021
and December 31, 2020 using a Black Scholes model, with the following observable and unobservable inputs:</p>

environment due to the COVID-19 pandemic and the property&#8217;s remote location has caused a lack of relevant comparable sales to use
as a basis for estimating fair value. At March 31, 2021, the Company estimated the fair value of the real estate based upon offers it

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The preparation of financial statements in conformity
with generally accepted accounting principles in the United States (&#8220;GAAP&#8221;) requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include oil and natural
gas reserves that are used in the calculation of depreciation, depletion, amortization and impairment of the carrying value of evaluated
oil and natural gas properties; realizability of unevaluated properties; production and commodity price estimates used to record accrued
oil and natural gas sales receivables; futures prices of commodities used in the valuation of commodity derivative contracts; valuation
of warrant instruments; valuation of real estate assets held for sale; and the cost of future asset retirement obligations. The Company
evaluates its estimates on an on-going basis and bases its estimates on historical experience and on various other assumptions the Company
believes to be reasonable. Due to inherent uncertainties, including the future prices of oil and natural gas, these estimates could change
in the near term and such changes could be material. In early March 2020, the NYMEX WTI crude oil price decreased significantly due to
the COVID-19 pandemic and although it has recovered to pre-COVID-19 levels, it remained low for most of 2020. Lower oil and natural gas
prices not only decrease our revenues, but an extended decline in oil or gas prices may materially and adversely affect our future business,
financial position, cash flows, results of operations, liquidity, ability to finance planned capital expenditures and the oil and natural
gas reserves that we can economically produce.</p><span></span>

Securities outstanding equals securities issued minus securities held in treasury. Temporary equity is a security with redemption features that are outside the control of the issuer, is not classified as an asset or liability in conformity with GAAP, and is not mandatorily redeemable. Includes any type of security that is redeemable at a fixed or determinable price or on a fixed or determinable date or dates, is redeemable at the option of the holder, or has conditions for redemption which are not solely within the control of the issuer. If convertible, the issuer does not control the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the conversion option if the holder exercises the option to convert the stock to another class of equity. If the security is a warrant or a rights issue, the warrant or rights issue is considered to be temporary equity if the issuer cannot demonstrate that it would be able to deliver upon the exercise of the option by the holder in all cases. Includes stock with put option held by ESOP and stock redeemable by holder only in the event of a change in control of the issuer.</p></div>
