PART I

General

Houston American Energy Corp is an independent oil and gas company focused on the development, exploration, exploitation, acquisition, and production of natural gas and crude oil

properties in the U.S. Gulf Coast region and in South America. Our oil and gas reserves and operations are concentrated primarily in the South American country of Colombia and in the onshore

Gulf Coast region, particularly Texas and Louisiana.

Our mission is to deliver outstanding net asset value per share growth to our investors via attractive oil and gas investments. Our strategy is to focus on early identification of, and

entrance into, existing and emerging resource plays, particularly in South America and the U.S. Gulf Coast. We typically seek to partner with larger operators in the development of resources or

retain interests, with or without contribution on our part, in prospects identified, packaged and promoted to larger operators. By entering these plays earlier and partnering with, or promoting to,

larger operators, we believe we can capture larger resource potential at lower cost and minimize our exposure to drilling risks and costs and ongoing operating costs.

We, along with our partners, actively manage our resources through opportunistic acquisitions and divestitures where reserves can be identified, developed, monetized and financial

resources redeployed with the objective of growing reserves, production and shareholder value.

Properties

Our exploration and development projects are focused on existing property interests, and future acquisition of additional property interests, in South America, particularly Colombia, and in

the onshore Texas Gulf Coast region and Louisiana.

Each of our properties differs in scope and character and consists of one or more types of assets, such as 3

- D seismic data, leasehold positions, lease options, working interests in leases,

partnership or limited liability company interests or other mineral rights. Our percentage interest in each property represents the portion of the interest in the property we share with other

partners in the property. Because each property consists of a bundle of assets that may or may not include a working interest in the project, our stated interest in a property simply represents our

proportional ownership in the bundle of assets that constitute the property. Therefore, our interest in a property should not be confused with the working interest that we will own when a given

well is drilled. Each of our exploration and development projects represents a negotiated transaction between the project partners relating to one or more properties. Our working interest may be

higher or lower than our stated interest. Filer: Houston American Energy Corp Form Type: 10

Item 1. Business

3Consistent with our strategy of opportunistically divesting holdings and redeploying financial resources to grow our reserve positions, in early 2012, our indirect interests in two

concessions in Colombia were sold for net proceeds, before escrow holdbacks, of $1.2 million. The interests sold accounted for 82% of our estimated proved oil and natural gas reserves at

December 31, 2011 and 7% of our oil and natural gas revenues in 2011. During 2012, proceeds from that sale were redeployed principally to exploration costs associated with our CPO 4 prospect

in Colombia.

The following table sets forth information relating to our principal properties as of December 31, 2012:

In March 2013, we entered into a settlement agreement with SK Innovation, operator of the 345,452 acre CPO 4 prospect in Colombia, pursuant to which we assigned to SK Innovation our

37.5% interest in the prospect and each party provided mutual releases of all rights and obligations relating to the prospect, including any obligation on our part relating to past and future

funding obligations.

- United States Properties:

In the United States, our properties and operations are principally located in the on

- shore Gulf Coast region of Louisiana and Texas.

Louisiana Properties

Our principal producing and exploration properties in Louisiana consist of the following:

4- Colombian Properties:

At December 31, 2012, we held interests in multiple prospects in Colombia covering 737,657 gross acres. As noted, during the first quarter of 2013, we terminated our interest in the 345,452

acre CPO 4 prospect. Giving effect to the termination of our interest in the CPO 4 prospect, our holdings in Colombia are located entirely within the Caguan Putumayo Basin. We identify our

Colombian prospects by the concessions operated.

The following table sets forth information relating to our interests in prospects in Colombia at December 31, 2012, giving effect to the subsequent termination of our interest in the CPO 4

prospect:

At December 31, 2012 we held interests in three concessions operated by Hupecol Operating Co. in Colombia. The Loc Picachos, Macaya and Serrania concessions are located in the

Caguan Putumayo Basin of Colombia. The concessions cover an aggregate area of 392,205 acres. Our interest in each of the concessions is subject to an escalating royalty ranging from 8% to

20% depending upon production volumes and pricing and an additional 6% to 10% per concession when 5,000,000 barrels of oil have been produced on a field in a concession.

During the first quarter of 2012, we sold our interest in the 48,000 La Cuerva concession and the 40,000 acre LLA 62 concession, both of which were operated by Hupecol. Included in our

interest sold in the La Cuerva concession was our entire interest in 16 gross (0.256 net) wells which accounted for approximately 51 barrels of oil per day to our interest at the time of sale. As of

December 31, 2012, no production had taken place on any of the fields in our then existing concessions in Colombia.

As operator of our various prospects, Hupecol has substantial control over the timing of drilling and selection of prospects to be drilled and we have limited ability to influence the

selection of prospects to be drilled or the timing of such drilling operations and have no effective means of controlling the costs of such drilling operations. Accordingly, our drilling budget is

subject to fluctuation based on the prospects selected to be drilled by Hupecol, the decisions of Hupecol regarding timing of such drilling operations and the ability of Hupecol to drill and

operate wells within estimated budgets.

For 2013, Hupecol has advised us that they plan to drill the first two wells on the Serrania concession as well as begin seismic on the Los Picachos and Macaya concessions. Hupecol ’ s

drilling and seismic plans for 2013 may change based on field conditions and other factors beyond our control or the control of Hupecol. Our estimated net cost associated with drilling the first

two wells on the Serrania concession as well as our portion of the seismic expenses related to the Los Picachos and Macaya concessions is approximately $2.5 million.

Serrania Block

Our interest in the Serrania concession was acquired through a Farmout Agreement with the original operator of the block pursuant to which we will pay 25% of designated Phase 1

geological and seismic costs in return for a 12.5% interest in the Contract for Exploration and Production covering the concession.

Seismic work on the Serrania Block was completed in 2010. Drilling preparation and seismic processing work was performed in 2011 and 2012 in connection with the planned drilling of

initial test wells on the concession. The National Hydrocarbon Agency of Colombia (the “ ANH ” ) has granted extensions of required development commitments, including drilling of a first test

well on the Serrania concession, until security conditions allow operations.

Los Picachos and Macaya Prospects

Our Los Picachos and Macaya prospects adjoin our Serrania concession. Hupecol has advised us that they plan to begin seismic on the Los Picachos and Macaya concessions during

2013. Filer: Houston American Energy Corp Form Type: 10

5Drilling Activity

During 2012, we participated in the drilling of a total of 5 gross wells, all of which were in Colombia. Of the 5 wells drilled, 3 were classified as exploratory and 2 were classified as

development. Our 2012 drilling program achieved a 40% success rate. The following table summarizes the number of wells drilled during 2012, 2011, and 2010, excluding any wells drilled under

farmout agreements, royalty interest ownership, or any other wells in which we do not have a working interest.

Productive wells are wells that are found to be capable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of the production exceed production expenses

and taxes.

As of December 31, 2012, we had no wells in progress or awaiting completion.

Productive Wells

Productive wells consist of producing wells and wells capable of production, including shut

- in wells. A well bore with multiple completions is counted as only one well. As of December

31, 2012, we owned interests in 6 gross wells. As of December 31, 2012, we had ownership interests in productive wells, categorized by geographic area, as follows: Filer: Houston American Energy Corp Form Type: 10

6Volume, Prices and Production Costs

The following table sets forth certain information regarding the production volumes, average prices received and average production costs associated with our sales of gas and oil,

categorized by geographic area, for each of the three years ended December 31, 2012:

Natural Gas and Oil Reserves

Reserve Estimates

The following tables sets forth, by country and as of December 31, 2012, our estimated net proved oil and natural gas reserves, and the estimated present value (discounted at an annual

rate of 10%) of estimated future net revenues before future income taxes (PV

- 10) and after future income taxes (Standardized Measure) of our proved reserves, each prepared in accordance with

assumptions prescribed by the Securities and Exchange Commission (SEC).

The PV

- 10 value is a widely used measure of value of oil and natural gas assets and represents a pre

- tax present value of estimated cash flows discounted at ten percent. PV

- 10 is

considered a non

- GAAP financial measure as defined by the SEC. We believe that our PV

- 10 presentation is relevant and useful to our investors because it presents the discounted future net

cash flows attributable to our proved reserves before taking into account the related future income taxes, as such taxes may differ among various companies because of differences in the

amounts and timing of deductible basis, net operating loss carry forwards and other factors. We believe investors and creditors use our PV

- 10 as a basis for comparison of the relative size and

value of our proved reserves to the reserve estimates of other companies. PV

- 10 is not a measure of financial or operating performance under GAAP and is not intended to represent the current

market value of our estimated oil and natural gas reserves. PV

- 10 should not be considered in isolation or as a substitute for the standardized measure of discounted future net cash flows as

defined under GAAP. Filer: Houston American Energy Corp Form Type: 10

7These calculations were prepared using standard geological and engineering methods generally accepted by the petroleum industry and in accordance with SEC financial accounting and

reporting standards.

Due to the inherent uncertainties and the limited nature of reservoir data, proved reserves are subject to change as additional information becomes available. The estimates of reserves,

future cash flows and present value are based on various assumptions, including those prescribed by the SEC, and are inherently imprecise. Although we believe these estimates are reasonable,

actual future production, cash flows, taxes, development expenditures, operating expenses and quantities of recoverable oil and natural gas reserves may vary substantially from these estimates.

Reserve Estimation Process, Controls and Technologies

The reserve estimates, including PV

- 10 and Standard Measure estimates, set forth above were prepared by Lonquist & Co., LLC.

(1) In accordance with applicable financial accounting and reporting standards of the SEC, the estimates of our proved reserves and the PV

- 10 set forth herein reflect estimated future gross

revenue to be generated from the production of proved reserves, net of estimated production and future development costs, using prices and costs under existing economic conditions

at December 31, 2012. For purposes of determining prices, we used the unweighted arithmetical average of the prices on the first day of each month within the 12

- month period ended

December 31, 2012. The average prices utilized for purposes of estimating our proved reserves were $95.05 per barrel of oil and $2.86 per mcf of natural gas for our US properties,

adjusted by property for energy content, quality, transportation fees and regional price differentials. The prices should not be interpreted as a prediction of future prices. The amounts

shown do not give effect to non

- property related expenses, such as corporate general administrative expenses and debt service, future income taxes or to depreciation, depletion and

amortization.

(2) Natural gas is converted on the basis of six Mcf of gas per one barrel of oil equivalent.

(3) The Standard Measure differs from PV

- 10 only in that the Standard Measure reflects estimated future income taxes.

8Our year

- end reserve report is prepared by Lonquist & Co. based upon a review of property interests being appraised, production from such properties, current costs of operation and

development, current prices for production, agreements relating to current and future operations and sale of production, geosciences and engineering data, and other information provided to

them by our management team. Lonquist & Co. also prepares reserve estimates for the various Hupecol entities. Upon analysis and evaluation of data provided, Lonquist & Co. issues a

preliminary appraisal report of our reserves. The preliminary appraisal report and changes in our reserves are reviewed by our President for reasonableness of the results obtained. Once any

questions have been addressed, Lonquist & Co. issues the final appraisal report, reflecting their conclusions.

Lonquist & Co. is an independent professional engineering firm specializing in the technical and financial evaluation of oil and gas assets. Lonquist & Co ’ s report was conducted under

the direction of Don E. Charbula, P.E., Vice President of Lonquist & Co. Mr. Charbula holds a BS in Petroleum Engineering from The University of Texas at Austin and is a registered professional

engineer with more than 30 years of experience in production engineering, reservoir engineering, acquisitions and divestments, field operations and management. Lonquist & Co., and its

employees, have no interest in our Company and were objective in determining our reserves.

The SEC ’ s rules with respect to technologies that a company can use to establish reserves allows use of techniques that have been proved effective by actual production from projects in

the same reservoir or an analogous reservoir or by other evidence using reliable technology that establishes reasonable certainty. Reliable technology is a grouping of one or more technologies

(including computational methods) that has been field tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being

evaluated or in an analogous formation.

Lonquist & Co. used a combination of production and pressure performance, simulation studies, offset analogies, seismic data and interpretation, geophysical logs and core data to

calculate our reserves estimates.

Proved Undeveloped Reserves

As of December 31, 2012, our proved undeveloped reserves totaled 0 mbbls of oil and 0 mcf of natural gas, for a total of 0 mbbls compared to 63.8 mbbls of oil and 0.0 mcf of natural gas, for

a total of 63.8 mbbls as of December 31, 2011.

Changes in Proved Undeveloped ( “ PUD ” ) Reserves

Changes in PUD Reserves that occurred during 2012 were due to the sale of our interest in the La Cuerva prospect which contained all of our PUD Reserves at December 31, 2011.

Developed and Undeveloped Acreage

The following table sets forth the gross and net developed and undeveloped acreage (including both leases and concessions), categorized by geographical area, which we held as of

December 31, 2012:

As noted above, subsequent to December 31, 2012, we agreed to transfer to SK Innovation our entire 37.5% interest in the 345,452 acre CPO 4 prospect in Colombia.

Developed acreage is comprised of leased acres that are within an area spaced by or assignable to a productive well. Undeveloped acreage is comprised of leased acres with defined

remaining terms and not within an area spaced by or assignable to a productive well.

As is customary in the oil and natural gas industry, we can generally retain our interest in undeveloped acreage by drilling activity that establishes commercial production sufficient to

maintain the leases or by paying delay rentals during the remaining primary term of leases. The oil and natural gas leases in which we have an interest are for varying primary terms and, if

production under a lease continues from our developed lease acreage beyond the primary term, we are entitled to hold the lease for as long as oil or natural gas is produced. Filer: Houston American Energy Corp Form Type: 10

2012, the expiration periods of the gross and net acres that are subject to leases or concessions summarized in the above table of undeveloped acreage.

Title to Properties

Title to properties is subject to royalty, overriding royalty, carried working, net profits, working and other similar interests and contractual arrangements customary in the gas and oil

industry, liens for current taxes not yet due and other encumbrances. As is customary in the industry in the case of undeveloped properties, little investigation of record title is made at the time

of acquisition (other than preliminary review of local records).

Investigation, including a title opinion of local counsel, generally is made before commencement of drilling operations.

Marketing

At December 31, 2012, we had no contractual agreements to sell our gas and oil production and all production was sold on spot markets.

Employees

As of December 31, 2012, we had 4 full

- time employees and no part time employees. The employees are not covered by a collective bargaining agreement, and we do not anticipate that any

of our future employees will be covered by such agreements.

Competition

We encounter intense competition from other oil and gas companies in all areas of our operations, including the acquisition of producing properties and undeveloped acreage. Our

competitors include major integrated oil and gas companies, numerous independent oil and gas companies and individuals. Many of our competitors are large, well

- established companies with

substantially larger operating staffs and greater capital resources and have been engaged in the oil and gas business for a much longer time than our Company. These companies may be able to

pay more for productive oil and gas properties, exploratory prospects and to define, evaluate, bid for and purchase a greater number of properties and prospects than our financial or human

resources permit. Our ability to acquire additional properties and to discover reserves in the future will be dependent upon our ability to evaluate and select suitable properties and to

consummate transactions in this highly competitive environment.

Regulatory Matters

Regulation of Oil and Gas Production, Sales and Transportation

The oil and gas industry is subject to regulation by numerous national, state and local governmental agencies and departments. Compliance with these regulations is often difficult and

costly and noncompliance could result in substantial penalties and risks. Most jurisdictions in which we operate also have statutes, rules, regulations or guidelines governing the conservation

of natural resources, including the unitization or pooling of oil and gas properties, minimum well spacing, plugging and abandonment of wells and the establishment of maximum rates of

production from oil and gas wells. Some jurisdictions also require the filing of drilling and operating permits, bonds and reports. The failure to comply with these statutes, rules and regulations

could result in the imposition of fines and penalties and the suspension or cessation of operations in affected areas. Filer: Houston American Energy Corp Form Type: 10

10Environmental Regulation

Various federal, state and local laws and regulations relating to the protection of the environment, including the discharge of materials into the environment, may affect our exploration,

development and production operations and the costs of those operations. These laws and regulations, among other things, govern the amounts and types of substances that may be released

into the environment, the issuance of permits to conduct exploration, drilling and production operations, the discharge and disposition of generated waste materials and waste management, the

reclamation and abandonment of wells, sites and facilities, financial assurance and the remediation of contaminated sites. These laws and regulations may impose substantial liabilities for

noncompliance and for any contamination resulting from our operations and may require the suspension or cessation of operations in affected areas.

The environmental laws and regulations applicable to our U.S. operations include, among others, the following United States federal laws and regulations:

Colombia has similar laws and regulations designed to protect the environment.

We routinely obtain permits for our facilities and operations in accordance with these applicable laws and regulations on an ongoing basis. There are no known issues that have a

significant adverse effect on the permitting process or permit compliance status of any of our facilities or operations.

The ultimate financial impact of these environmental laws and regulations is neither clearly known nor easily determined as new standards are enacted and new interpretations of existing

standards are rendered. Environmental laws and regulations are expected to have an increasing impact on our operations. In addition, any non

- compliance with such laws could subject us to

material administrative, civil or criminal penalties, or other liabilities. Potential permitting costs are variable and directly associated with the type of facility and its geographic location. Costs, for

example, may be incurred for air emission permits, spill contingency requirements, and discharge or injection permits. These costs are considered a normal, recurring cost of our ongoing

operations and not an extraordinary cost of compliance with government regulations.

Although we do not operate the properties in which we hold interests, noncompliance with applicable environmental laws and regulations by the operators of our oil and gas properties

could expose us, and our properties, to potential costs and liabilities associated with such environmental laws. While we exercise no oversight with respect to any of our operators, we believe

that each of our operators is committed to environmental protection and compliance. However, since environmental costs and liabilities are inherent in our operations and in the operations of

companies engaged in similar businesses and since regulatory requirements frequently change and may become more stringent, there can be no assurance that material costs and liabilities will

not be incurred in the future. Such costs may result in increased costs of operations and acquisitions and decreased production. Filer: Houston American Energy Corp Form Type: 10

11Climate Change Legislation and Greenhouse Gas Regulation

Federal, state and local laws and regulations are increasingly being enacted to address concerns about the effects the emission of “ greenhouse gases ” may have on the environment and

climate worldwide. These effects are widely referred to as “ climate change. ” Since its December 2009 endangerment finding regarding the emission of greenhouse gases, the EPA has begun

regulating sources of greenhouse gas emissions under the federal Clean Air Act. Among several regulations requiring reporting or permitting for greenhouse gas sources, the EPA finalized its

“ tailoring rule ” in May 2010 that determines which stationary sources of greenhouse gases are required to obtain permits to construct, modify or operate on account of, and to implement the best

available control technology for, their greenhouse gases. In November 2010, the EPA also finalized its greenhouse gas reporting requirements, beginning in March 2012, for certain oil and gas

production facilities.

Moreover, in recent past the U.S. Congress has considered establishing a cap

- and

- trade program to reduce U.S. emissions of greenhouse gases. Under past proposals, the EPA would

issue or sell a capped and steadily declining number of tradable emissions allowances to certain major sources of greenhouse gas emissions so that such sources could continue to emit

greenhouse gases into the atmosphere. These allowances would be expected to escalate significantly in cost over time. The net effect of such legislation, if ever adopted, would be to impose

increasing costs on the combustion of carbon

- based fuels such as crude oil, refined petroleum products, and natural gas. In addition, while the prospect for such cap

- and

- trade legislation by the

U.S. Congress remains uncertain, several states have adopted, or are in the process of adopting, similar cap

- and

- trade programs.

As a crude oil and natural gas company, the debate on climate change is relevant to our operations because the equipment we use to explore for, develop and produce crude oil and

natural gas emits greenhouse gases. Additionally, the combustion of carbon

- based fuels, such as the crude oil and natural gas we sell, emits carbon dioxide and other greenhouse gases. Thus,

any current or future federal, state or local climate change initiatives could adversely affect demand for the crude oil and natural gas we produce by stimulating demand for alternative forms of

energy that do not rely on the combustion of fossil fuels, and therefore could have a material adverse effect on our business. Although our compliance with any greenhouse gas regulations may

result in increased compliance and operating costs, we do not expect the compliance costs for currently applicable regulations to be material. Moreover, while it is not possible at this time to

estimate the compliance costs or operational impacts for any new legislative or regulatory developments in this area, we do not anticipate being impacted to any greater degree than other

similarly situated competitors.

12Our business activities and the value of our securities are subject to significant hazards and risks, including those described below. If any of such events should occur, our business,

financial condition, liquidity and/or results of operations could be materially harmed, and holders and purchasers of our securities could lose part or all of their investments.

Our cash flows and profitability may fluctuate by large amounts as a result of our strategy of investment in drilling and exploration of unproven properties and opportunistic asset

divestitures.

We have historically experienced large fluctuations in our cash flows and profitability associated with our drilling and development of properties, divestitures of interests in select

properties and reinvestment in drilling and development of unproven properties. Our strategy has historically focused on early identification of, and entrance into, existing and emerging

resource plays. As part of that strategy, we and our partners have participated in accumulating positions and drilling unproven acreage, that may be perceived to be higher risk, where

acquisition, drilling and operation costs may be lower with a view to proving reserves, divesting selected assets on an opportunistic basis to operators willing to pay higher prices for proven

prospects without early stage drilling risk and reinvesting operating cash flow and sales proceeds in accumulating, drilling and developing additional, and larger, acreage positions. As a result

of such strategy, we sold acreage positions in 2008, 2010 and 2012 that provided one

- time profits and cash proceeds and substantially reduced our proved reserves, production and operating

cash flows immediately following such sales and after which we invested substantial portions of sales proceeds in the accumulation and exploratory drilling of larger acreage positions. While

our reserves, production, operating cash flows and operating profitability have historically grown as properties have been drilled and developed and have fallen following strategic asset

divestitures when we are incurring costs to drill and develop properties, there is no assurance that our strategy will produce such results in the future and, in fact, that strategy did not produce

new reserves, production, cash flow or profitability when deployed on our CPO 4 prospect. As a result of drilling and other risks, there can be no assurance that our reserve and production

growth strategy will allow us to grow, and replace, our acreage position, reserves, production and profitability following divestitures and we may continue to experience large fluctuations in such

positions.

Our divestiture strategy exposes us to risks associated with a lack of diversification and a concentration of properties, increased dependence on a small number of properties and

disproportionate risk of loss associated with drilling results and operations of one or a small number of properties.

Because a significant element of our strategy has been the opportunistic divestiture of properties and redeployment of resources to new properties, we have historically been focused on

development of a small number of geographically concentrated prospects. Accordingly, we lack diversification with respect to the nature and geographic location of our holdings. As a result,

we are exposed to higher dependence on individual resource plays and may experience substantial losses should a single individual prospect prove unsuccessful. Absent other operating

properties, the failure or underperformance of a single prospect could materially adversely affect our financial resources, reserve and production outlook and profitability. In particular, during

2011 and 2012 we committed a substantial portion of the proceeds received from our 2010 divestiture of Hupecol properties to a drilling program on our CPO 4 prospect. Between 2011 and 2012,

we participated in the drilling of three test wells on our CPO 4 prospect, each of which was determined to be noncommercial and, ultimately, plugged and abandoned. Given our focus on

development of the CPO 4 prospect, including the commitment of substantial financial resources and the lack of current production from our other prospects, the failure to complete a commercial

well on the prospect materially adversely affected our financial position and operating outlook.

Unless we replace our oil and natural gas reserves, our reserves and production will decline, which would adversely affect our cash flows and income.

Unless we conduct successful development, exploitation and exploration activities or acquire properties containing proved reserves, our proved reserves will decline as those reserves are

produced. Producing oil and natural gas reservoirs generally are characterized by declining production rates that vary depending upon reservoir characteristics and other factors. Our future oil

and natural gas reserves and production, and, therefore our cash flow and income, are highly dependent on our success in efficiently developing and exploiting our current reserves and

economically finding or acquiring additional recoverable reserves. If we are unable to develop, exploit, find or acquire additional reserves to replace our current and future production, our cash

flow and income will decline as production declines, until our existing properties would be incapable of sustaining commercial production. Filer: Houston American Energy Corp Form Type: 10

Item 1A. Risk Factors

13A substantial percentage of our properties are unproven and undeveloped; therefore the cost of proving and developing our properties and risk associated with our success is greater than

would be the case if the majority of our properties were categorized as proved developed producing.

Because a substantial percentage of our properties are unproven and undeveloped, we require significant capital to prove and develop such properties before they may become

productive. Following the sale of our principal producing property in Colombia in March 2012, substantially all of our net acreage was unproven and undeveloped. Because of the inherent

uncertainties associated with drilling for oil and gas, some of these properties may never be successfully drilled and developed to the extent that they result in positive cash flow. Even if we are

successful in our drilling and development efforts, it could take several years for a significant portion of our unproven properties to be converted to positive cash flow.

Prospects that we decide to drill may not yield oil or natural gas in commercially viable quantities.

Our prospects are properties on which we have identified what we believe, based on available seismic and geological information, to be indications of oil or natural gas potential. Our

prospects are in various stages of evaluation, ranging from a prospect that is ready to drill to a prospect that will require substantial seismic data processing and interpretation. There is no way

to predict in advance of drilling and testing whether any particular prospect will yield oil or natural gas in sufficient quantities to recover drilling or completion costs or to be economically viable.

The use of seismic data and other technologies and the study of producing fields in the same area will not enable us to know conclusively prior to drilling whether oil or natural gas will be

present or, if present, whether oil or natural gas will be present in commercial quantities. We cannot assure that the analogies we draw from available data from other wells, more fully explored

prospects or producing fields will be applicable to our drilling prospects.

Drilling for and producing oil and natural gas are high risk activities with many uncertainties that could adversely affect our business, financial condition or results of operations.

Our future success will depend on the success of our exploitation, exploration, development and production activities. Our oil and natural gas exploration and production activities are

subject to numerous risks beyond our control, including the risk that drilling will not result in commercially viable oil or natural gas production. Our decisions to purchase, explore, develop or

otherwise exploit prospects or properties will depend in part on the evaluation of data obtained through geophysical and geological analyses, production data and engineering studies, the

results of which are often inconclusive or subject to varying interpretations. Please read “ Reserve estimates depend on many assumptions that may turn out to be inaccurate ” ( below) for a

discussion of the uncertainty involved in these processes. Our cost of drilling, completing and operating wells is often uncertain before drilling commences. Overruns in budgeted expenditures

are common risks that can make a particular project uneconomical. Further, many factors may curtail, delay or cancel drilling, including the following:

Cost overruns, curtailments, delays and cancellations of operations as a result of the above factors and other factors common in our industry may materially adversely affect our

operating results and financial position and our ability to maintain our interests in prospects. Filer: Houston American Energy Corp Form Type: 10

14We may incur substantial uninsured losses and be subject to substantial liability claims as a result of our oil and natural gas operations.

We are not insured against all risks. Losses and liabilities arising from uninsured and underinsured events could materially and adversely affect our business, financial condition or results

of operations. Our oil and natural gas exploration and production activities are subject to all of the operating risks associated with drilling for and producing oil and natural gas, including the

possibility of:

Any of these risks could adversely affect our ability to conduct operations or result in substantial losses to our company. We may elect not to obtain insurance if we believe that the cost

of available insurance is excessive relative to the risks presented. In addition, pollution and environmental risks generally are not fully insurable. The occurrence of a significant accident or other

event that is not fully covered by insurance could have a material adverse effect on our business, results of operations or financial condition.

We are dependent upon third party operators of our oil and gas properties.

Under the terms of the operating agreements related to our oil and gas properties, third parties act as the operator of each of our oil and gas wells and control the drilling and operating

activities to be conducted on our properties. Therefore, we have limited control over certain decisions related to activities on our properties, which could affect our results of operations.

Decisions over which we have limited control include:

Decisions made by our operators may be different than those we would make reflecting priorities different than our priorities and may materially adversely affect our operating results and

financial position.

The unavailability or high cost of drilling rigs, equipment, supplies, personnel and oil field services could adversely affect our ability to execute on a timely basis our exploration and

development plans within our budget.

Shortages or the high cost of drilling rigs, equipment, supplies or personnel could delay or adversely affect our development and exploration operations. As the price of oil and natural gas

increases, the demand for production equipment and personnel will likely also increase, potentially resulting, at least in the near

- term, in shortages of equipment and personnel. In addition, larger

producers may be more likely to secure access to such equipment by virtue of offering drilling companies more lucrative terms. If we are unable to acquire access to such resources, or can obtain

access only at higher prices, not only would this potentially delay our ability to convert our reserves into cash flow, but could also significantly increase the cost of producing those reserves,

thereby negatively impacting anticipated net income. Filer: Houston American Energy Corp Form Type: 10

15We may need additional financing to support operations and future capital commitments.

At December 31, 2012, our estimated drilling budget for 2013 was approximately $2.5 million, principally relating to the drilling of two test wells on the Serrania prospect as well as shooting

seismic on the Los Picachos and Macaya Concessions. While we believe that our cash on hand at December 31, 2012, together with funds expected to be received from federal tax refunds and

the release of certain restricted funds, will support or drilling budget and overhead during 2013, there is no assurance that we will not require additional financing to support drilling operations

and other cash requirements during 2013 or in future years. Our drilling budget can vary substantially based on the timing and results of drilling operations as well as determinations to

participate in the drilling and development of new prospects. We have no commitments to provide any additional financing and there is no guarantee that we will be able to secure additional

financing on acceptable terms, or at all, if needed to fully fund our 2013 drilling budget and to support future acquisitions and development activities.

If our access to markets is restricted, it could negatively impact our production, our income and ultimately our ability to retain our leases.

Market conditions or the unavailability of satisfactory transportation arrangements may hinder our access to oil and natural gas markets or delay our production. The availability of a

ready market for our oil and natural gas production depends on a number of factors, including the demand for and supply of oil and natural gas and the proximity of reserves to pipelines and

terminal facilities. Our ability to market our production depends in substantial part on the availability and capacity of gathering systems, pipelines and processing facilities owned and operated

by third parties. Our failure to obtain such services on acceptable terms could materially harm our business.

We may operate in areas with limited or no access to pipelines, thereby necessitating delivery by other means, such as trucking, or requiring compression facilities. Such restrictions on

our ability to sell our oil or natural gas could have several adverse effects, including higher transportation costs, fewer potential purchasers (thereby potentially resulting in a lower selling price)

or, in the event we were unable to market and sustain production from a particular lease for an extended time, possibly causing us to lose a lease due to lack of production.

A substantial or extended decline in oil and natural gas prices may adversely affect our business, financial condition or results of operations and our ability to meet our capital

expenditure obligations and financial commitments.

The price we receive for our oil and natural gas production heavily influences our revenue, profitability, access to capital and future rate of growth. Oil and natural gas are commodities

and, therefore, their prices are subject to wide fluctuations in response to relatively minor changes in supply and demand. Historically, the markets for oil and natural gas have been volatile.

These markets will likely continue to be volatile in the future. The prices we receive for our production, and the levels of our production, depend on numerous factors beyond our control. These

factors include, but are not limited to, the following: Filer: Houston American Energy Corp Form Type: 10

16Lower oil and natural gas prices may not only decrease our revenues on a per unit basis but also may reduce the amount of oil and natural gas that we can produce economically. Lower

prices will also negatively impact the value of our proved reserves. A substantial or extended decline in oil or natural gas prices may materially and adversely affect our future business, financial

condition, results of operations, liquidity or ability to finance planned capital expenditures.

Global economic growth drives demand for energy from all sources, including fossil fuels. Should the U.S. and global economies experience weakness, such as that experienced during the

global financial crisis of 2008

- 2009, demand for energy and accompanying commodity prices may decline and our financial position may deteriorate along with our ability to operate profitably and

our ability to obtain financing to support operations and the cost and terms of the same, is unclear. With respect to our business, the crisis experienced during the 2008

- 2009 period resulted in a

steep decline in the price of oil and natural gas, a marked decline in the value of our reserves, a determination in March 2009 to temporarily shut

- in production from our Colombian wells and

reduced revenues and profitability.

If oil and natural gas prices decrease, we may be required to take write

- downs of the carrying values of our oil and natural gas properties, potentially negatively impacting the trading

value of our securities.

Accounting rules require that we review periodically the carrying value of our oil and natural gas properties for possible impairment. Based on specific market factors and circumstances at

the time of prospective impairment reviews, and the continuing evaluation of development plans, production data, economics and other factors, we have and may be required to further write

down the carrying value of our oil and natural gas properties. A write

- down would constitute a non

- cash charge to earnings. It is likely the cumulative effect of a write

- down could also

negatively impact the trading price of our securities.

Reserve estimates depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions will materially affect the

quantities and present value of our reserves.

The process of estimating oil and natural gas reserves is complex, requiring interpretations of available technical data and many assumptions, including assumptions relating to economic

factors. Any significant inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of reserves reported.

In order to prepare our estimates, we must project production rates and timing of development expenditures. We must also analyze available geological, geophysical, production and

engineering data. The extent, quality and reliability of this data can vary. The process also requires economic assumptions about matters such as oil and natural gas prices, drilling and operating

expenses, capital expenditures, taxes and availability of funds. Therefore, estimates of oil and natural gas reserves are inherently imprecise.

Actual future production, oil and natural gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oil and natural gas reserves most likely

will vary from our estimates. Any significant variance could materially affect the estimated quantities and present value of our reserves. In addition, we may adjust estimates of proved reserves to

reflect production history, results of exploration and development activities, prevailing oil and natural gas prices and other factors, many of which are beyond our control.

The present value of future net revenues from our proved reserves, as reported from time to time, should not be assumed to be the current market value of our estimated oil and natural gas

reserves. In accordance with SEC requirements, we generally base the estimated discounted future net cash flows from our proved reserves on costs on the date of the estimate and average

prices over the preceding twelve months. Actual future prices and costs may differ materially from those used in the present value estimate. If future prices decline or costs increase it could

negatively impact our ability to finance operations, and individual properties could cease being commercially viable, affecting our decision to continue operations on producing properties or to

attempt to develop properties. All of these factors would have a negative impact on earnings and net income, and most likely the trading price of our securities. Filer: Houston American Energy Corp Form Type: 10

17Our operations in Colombia are subject to risks relating to political and economic instability.

We currently have interests in multiple oil and gas concessions in Colombia and anticipate that operations in Colombia will constitute a substantial element of our strategy going forward.

The political climate in Colombia is unstable and could be subject to radical change over a very short period of time. In the event of a significant negative change in the political or economic

climate in Colombia, we may be forced to abandon or suspend our operations in Colombia.

A 40

- year armed conflict between government forces and anti

- government insurgent groups and illegal paramilitary groups

— both funded by the drug trade

— continues in Colombia.

Insurgents continue to attack civilians and violent guerilla activity continues in many parts of the country. While our operators take measures to protect our assets, operations and personnel

from guerilla activity, continuing attempts to reduce or prevent guerilla activity may not be successful and guerilla activity may disrupt our operations in the future. There can also be no

assurance that we can maintain the safety of our operations and personnel in Colombia or that this violence will not affect our operations in the future. Continued or heightened security

concerns in Colombia could also result in a significant loss to us.

Additionally, Colombia is among several nations whose eligibility to receive foreign aid from the United States is dependent on its progress in stemming the production and transit of

illegal drugs, which is subject to an annual review by the President of the United States. Although Colombia is currently eligible for such aid, Colombia may not remain eligible in the future. A

finding by the President that Colombia has failed demonstrably to meet its obligations under international counternarcotics agreements may result in any of the following:

Each of these consequences could result in adverse economic consequences in Colombia and could further heighten the political and economic risks associated with our operations there.

Any changes in the holders of significant government offices could have adverse consequences on our relationship with key governmental agencies and the Colombian government ’ s ability to

control guerrilla activities and could exacerbate the factors relating to our foreign operations. Any sanctions imposed on Colombia by the United States government could threaten our ability to

obtain necessary financing to develop the Colombian properties or cause Colombia to retaliate against us, including by nationalizing our Colombian assets. Accordingly, the imposition of the

foregoing economic and trade sanctions on Colombia would likely result in a substantial loss and a decrease in the price of our common stock. The United States may impose sanctions on

Colombia in the future, and we cannot predict the effect in Colombia that these sanctions might cause.

Our operations in Colombia are controlled by operators which may carry out transactions affecting our Colombian assets and operations without our consent.

Our operations in Colombia are subject to a substantial degree of control by the operators of the properties in which we hold interests in Colombia. We are an investor in a number of

properties operated by Hupecol and our interest in the assets and operations of Hupecol related entities and ventures represent a substantial portion of our current assets in Colombia. During

2008, 2010 and 2012, respectively, Hupecol sold its interest in multiple concessions and entities holding multiple concessions each representing, at the time, the largest prospect(s) in terms of

reserves and revenues in which we then held an interest. In early March 2009, Hupecol determined to temporarily shut

- in production from our Colombian properties. It is possible that Hupecol

will carry out similar sales or acquisitions of prospects or make similar decisions in the future. Our management intends to closely monitor the nature and progress of future transactions by

Hupecol in order to protect our interests. However, we have no effective ability to alter or prevent a transaction and are unable to predict whether or not any such transactions will in fact occur

or the nature or timing of any such transaction. Filer: Houston American Energy Corp Form Type: 10

● all bilateral aid, except anti

- narcotics and humanitarian aid, would be suspended;

● the Export

- Import Bank of the United States and the Overseas Private Investment Corporation would not approve financing for new projects in Colombia;

● United States representatives at multilateral lending institutions would be required to vote against all loan requests from Colombia, although such votes would not constitute

vetoes; and

● the President of the United States and Congress would retain the right to apply future trade sanctions.

18In addition to the control exercised by Hupecol with respect to the properties it operates, as minority owners, we are, or may be, subject to substantial control of other properties in

Colombia in which we hold interests that are operated by third party operators, other than Hupecol. Our Colombian assets presently consist, and in the future are expected to continue to consist,

exclusively of minority, non

- operator project interests in certain Colombian assets owned and operated by third party operators. Our passive investments in such Colombian assets constitute

our principal assets, and as a result, our financial results are directly affected by the independent strategies and decisions of the operators of those properties.

We may be exposed to additional expenses and losses arising from the financial position of our joint interest partners in Colombia.

Our Colombian properties are developed under financial arrangements with various joint interest partners. If other joint interest partners are unable, or unwilling, to satisfy their various

obligations relating to prospects, we may be required to pay a proportionately higher share of development costs on those prospects or the prospect may be inadequately capitalized to achieve

optimal results.

We may be exposed to substantial fines and penalties if we or our partners fail to comply with laws and regulations associated with our activities in foreign countries, including Colombia,

regarding U.S. laws such as the Foreign Corrupt Practices Act and local laws prohibiting corrupt payments to governmental officials and other corrupt practices.

Our Colombian assets constitute our principal assets and consist exclusively of minority, non

- operator project interests. Third parties act as the operator of each of our oil and gas wells

and control all drilling and operating activities conducted with respect to our Colombian properties. Therefore, we have limited control over decisions related to activities on our properties, and

we cannot provide assurance that our partners or their employees, contractors or agents will not take actions in violation of applicable anti

- corruption laws and regulations. In the course of

conducting business in Colombia, we have relied primarily on the representations and warranties made by our operating and non

- operating partners in the farmout and joint operating agreements

which govern our respective project interests to the effect that:

While we periodically inquire as to the continuing accuracy of these representations, as a minority non

- operator, we are limited in our ability to assure compliance. Consequently, we

cannot provide assurance that the procedural safeguards, if any, adopted by our partners or the representations and warranties contained in these agreements and our reliance on them will

protect us from liability should a violation occur. Any violations of the anti

- bribery, accounting controls or books and records provisions of the Foreign Corrupt Practices Act by us or our

partners could subject us and, where deemed appropriate, individuals, in certain cases, to a broad range of civil and criminal penalties, including but not limited to, imprisonment, injunctive relief,

disgorgement, substantial fines or penalties, prohibitions on our ability to offer our products in one or more countries, imposed modifications to business practices and compliance programs,

including retention of an independent monitor to oversee compliance, and could also materially damage our reputation, our business and our operating results.

Our operations will be subject to environmental and other government laws and regulations that are costly and could potentially subject us to substantial liabilities.

Crude oil and natural gas exploration and production operations in the United States and in Colombia are subject to extensive federal, state and local laws and regulations. Oil and gas

companies are subject to laws and regulations addressing, among others, land use and lease permit restrictions, bonding and other financial assurance related to drilling and production

activities, spacing of wells, unitization and pooling of properties, environmental and safety matters, plugging and abandonment of wells and associated infrastructure after production has

ceased, operational reporting and taxation. Failure to comply with such laws and regulations can subject us to governmental sanctions, such as fines and penalties, as well as potential liability

for personal injuries and property and natural resources damages. We may be required to make significant expenditures to comply with the requirements of these laws and regulations, and future

laws or regulations, or any adverse change in the interpretation of existing laws and regulations, could increase such compliance costs. Regulatory requirements and restrictions could also delay

or curtail our operations and could have a significant impact on our financial condition or results of operations. Filer: Houston American Energy Corp Form Type: 10

19Our oil and gas operations are subject to stringent laws and regulations relating to the release or disposal of materials into the environment or otherwise relating to environmental

protection. These laws and regulations:

Failure to comply with these laws and regulations may result in:

Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent or costly waste handling, storage, transport, disposal or cleanup

requirements could require us to make significant expenditures to attain and maintain compliance and may otherwise have a material adverse effect on our industry in general and on our own

results of operations, competitive position or financial condition. Although we intend to be in compliance in all material respects with all applicable environmental laws and regulations, we

cannot assure you that we will be able to comply with existing or new regulations. In addition, the risk of accidental spills, leakages or other circumstances could expose us to extensive liability.

We are unable to predict the effect of additional environmental laws and regulations that may be adopted in the future, including whether any such laws or regulations would materially

adversely increase our cost of doing business or affect operations in any area.

Under certain environmental laws that impose strict, joint and several liability, we may be required to remediate our contaminated properties regardless of whether such contamination

resulted from the conduct of others or from consequences of our own actions that were or were not in compliance with all applicable laws at the time those actions were taken. In addition, claims

for damages to persons or property may result from environmental and other impacts of our operations. Moreover, new or modified environmental, health or safety laws, regulations or

enforcement policies could be more stringent and impose unforeseen liabilities or significantly increase compliance costs. Therefore, the costs to comply with environmental, health or safety

laws or regulations or the liabilities incurred in connection with them could significantly and adversely affect our business, financial condition or results of operations. In addition, many

countries as well as several states and regions of the U.S. have agreed to regulate emissions of “ greenhouse gases. ” Methane, a primary component of natural gas, and carbon dioxide, a

byproduct of burning of natural gas and oil, are greenhouse gases. Regulation of greenhouse gases could adversely impact some of our operations and demand for some of our services or

products in the future.

Certain U.S. federal income tax deductions currently available with respect to oil and gas exploration and development may be eliminated as a result of future legislation.

The Obama Administration has proposed legislation that would, if enacted into law, make significant changes to United States tax laws, including the elimination of certain key U.S. federal

income tax incentives currently available to oil and natural gas exploration and production companies. These changes include, but are not limited to, (i) the repeal of the percentage depletion

allowance for oil and natural gas properties, (ii) the elimination of current deductions for intangible drilling and development costs, (iii) the elimination of the deduction for certain domestic

production activities, and (iv) an extension of the amortization period for certain geological and geophysical expenditures. It is unclear whether any such changes will be enacted or how soon

any such changes could become effective. The passage of any legislation as a result of these proposals or any other similar changes in U.S. federal income tax laws could eliminate certain tax

deductions that are currently available with respect to oil and gas exploration and development, and any such change could negatively affect our financial condition and results of operations. Filer: Houston American Energy Corp Form Type: 10

20Competition in the oil and natural gas industry is intense, which may adversely affect our ability to compete.

We operate in a highly competitive environment for acquiring properties, marketing oil and natural gas and securing trained personnel. Many of our competitors possess and employ

financial, technical and personnel resources substantially greater than ours, which can be particularly important in the areas in which we operate. Those companies may be able to pay more for

productive oil and natural gas properties and exploratory prospects and to evaluate, bid for and purchase a greater number of properties and prospects than our financial or personnel resources

permit. Our ability to acquire additional prospects and to find and develop reserves in the future will depend on our ability to evaluate and select suitable properties and to consummate

transactions in a highly competitive environment. Also, there is substantial competition for capital available for investment in the oil and natural gas industry. We may not be able to compete

successfully in the future in acquiring prospective reserves, developing reserves, marketing hydrocarbons, attracting and retaining quality personnel and raising additional capital.

Our success depends on our management team and other key personnel, the loss of any of whom could disrupt our business operations.

Our success will depend on our ability to attract and retain our management and non

- management employees, including engineers, geoscientists and other technical and professional staff

and, in particular, our President, John Terwilliger, who is principally responsible for sourcing our resource plays. We will depend, to a large extent, on the efforts, technical expertise and

continued employment of such personnel and members of our management team. If members of our management team should resign or we are unable to attract the necessary personnel, our

business operations could be adversely affected.

The price of our common stock may fluctuate significantly, and this may make it difficult to resell common stock when, or at prices, desired.

The price of our common stock constantly changes. We expect that the market price of our common stock will continue to fluctuate.

Our stock price may fluctuate as a result of a variety of factors, many of which are beyond our control. These factors include: Filer: Houston American Energy Corp Form Type: 10

21Our stock has suffered significant declines over the past year mirroring, among other things, the delays in drilling and ultimate determination to cease completion efforts on test wells on

the CPO 4 prospect and the announcement that the SEC is conducting an investigation of our company.

In addition, in recent years, the stock market in general has experienced extreme price and volume fluctuations. This volatility has had a significant effect on the market price of securities

issued by many companies for reasons often unrelated to their operating performance. These broad market fluctuations may adversely affect our stock price, regardless of our operating results.

The sale of a substantial number of shares of our common stock may affect our stock price.

Future sales of substantial amounts of our common stock or equity

- related securities in the public market or privately, or the perception that such sales could occur, could adversely affect

prevailing trading prices of our common stock and could impair our ability to raise capital through future offerings of equity or equity

- related securities. No prediction can be made as to the

effect, if any, that future sales of shares of common stock or the availability of shares of common stock for future sale will have on the trading price of our common stock.

Our charter and bylaws, as well as provisions of Delaware law, could make it difficult for a third party to acquire our company and also could limit the price that investors are willing to

pay in the future for shares of our common stock.

Delaware corporate law and our charter and bylaws contain provisions that could delay, deter or prevent a change in control of our Company or our management. These provisions could

also discourage proxy contests and make it more difficult for our stockholders to elect directors and take other corporate actions without the concurrence of our management or board of

directors. These provisions:

We are also subject to anti

- takeover provisions under Delaware law, which could also delay or prevent a change of control. Taken together, these provisions of our charter, bylaws, and

Delaware law may discourage transactions that otherwise could provide for the payment of a premium over prevailing market prices of our common stock and also could limit the price that

investors are willing to pay in the future for shares of our common stock.

Our management owns a significant amount of our common stock, giving them influence or control in corporate transactions and other matters, and their interests could differ from those

of other shareholders.

At December 31, 2012, our directors and executive officers owned approximately 21.4% of our outstanding common stock. As a result, our current directors and executive officers are in a

position to significantly influence or control the outcome of matters requiring a shareholder vote, including the election of directors, the adoption of any amendment to our certificate of

incorporation or bylaws, and the approval of mergers and other significant corporate transactions. Such level of control of the Company may delay or prevent a change of control on terms

favorable to the other shareholders and may adversely affect the voting and other rights of other shareholders. Filer: Houston American Energy Corp Form Type: 10

22We may incur costs and be subject to sanctions and uncertainties relating to the ongoing investigation of our company by the SEC.

We are the subject of an ongoing formal investigation by the SEC. Pursuant to the investigation, we received subpoenas issued by the SEC calling for the testimony of our principal

officers and the delivery of certain documents. The subpoenas were issued pursuant to a nonpublic formal order of private investigation issued by the SEC on March 1, 2011, which followed a

nonpublic informal inquiry commenced by the SEC in October 2010. We received a copy of the nonpublic formal order of private investigation on February 10, 2012 in connection with a February

2012 subpoena issued by the SEC. The SEC has indicated that it is trying to determine whether there have been any violations of the federal securities laws and appears to have narrowed the

focus of their investigation to matters relating to disclosure of reserve potential on the CPO 4 prospect. A determination by the SEC that we have violated the U.S. securities laws would likely

have a material adverse effect on our consolidated financial position, results of operations or cash flows.

We could be negatively impacted by securities class action complaints.

On April 27, 2012, a purported class action lawsuit was filed in the U.S. District Court for the Southern District of Texas against us and certain of our executive officers, which we refer to as

the Silverman litigation. The complaint generally alleges that, between March 29, 2010 and April 18, 2012, all of the defendants violated Sections 10(b) of the Securities Exchange Act of 1934 and

SEC Rule 10b

- 5 and the individual defendants violated Section 20(a) of the Exchange Act in making materially false and misleading statements including certain statements related to the status

and viability of the first test well on the CPO 4 prospect. The complaint seeks unspecified damages, interest, attorneys ’ fees, and other costs. It will take time and money to defend against this

suit and may distract us from more productive activities. We may not be successful in defending this litigation, and insurance proceeds may not be sufficient to cover any liability under such

claims. Additional class actions have since been filed against us, and may in the future be filed against us, as a result of, or based on, the same factual allegations set out in the Silverman

litigation and all such actions would also take time and corporate resources to defend against. If the plaintiffs in the Silverman litigation, or the plaintiffs in any other class action litigation, are

successful in their litigation, the payment by us of damages, interest, attorneys ’ fees and costs would have a material adverse effect on our consolidated financial position, results of operations,

or cash flows.

We are subject to uncertainty with respect to the calculation of certain tax obligations in Colombia and may incur additional tax liability in Colombia.

At December 31, 2012, we had engaged our tax advisors in Colombia to evaluate certain tax and other filings made in Colombia by them and other advisors for 2009, 2010 and 2011. Our

advisors identified inconsistencies between tax and non

- tax filings with respect to equity investments made in Colombia. Based on guidance from our advisors, we estimated and recorded a

foreign tax liability related to these matters of approximately $1.9 million in 2012. It is possible that we may be subject to additional tax obligations in Colombia related to these matters; if based

upon a review of the work performed by our advisors, the Colombian tax authority and regulatory agencies disagree with our advisors assessment.

Not applicable.

We currently lease approximately 4,739 square feet of office space in Houston, Texas as our executive offices. Management anticipates that our space will be sufficient for the foreseeable

future. The average monthly rental under the lease, which expires on May 31, 2017, is $7,701. A description of our interests in oil and gas properties is included in “ Item 1. Business. ” Filer: Houston American Energy Corp Form Type: 10

the Securities Exchange Act of 1934 and SEC Rule 10b

- 5 and the individual defendants violated Section 20(a) of the Exchange Act in making materially false and misleading statements including

interest, attorneys ’ fees, and other costs. On September 20, 2012, the court consolidated the class action lawsuits and appointed a lead plaintiff and on November 15, 2012 the lead plaintiffs filed

an amended complaint. On January 14, 2013, we filed a motion to dismiss which remains pending before the court. We believe all of the claims in the consolidated class action lawsuits are

without merit and intend to vigorously defend against these claims. It is not possible at this time to predict the timing or outcome of the class action lawsuits that have or may be filed.

American Energy, as nominal defendant: E. Howard King, Jr., derivatively, on behalf of Houston American Energy Corp., v. John F. Terwilliger, John P. Boylan, Orrie Lee Tawes III, Stephen

Hartzell, James J. Jacobs, Kenneth A. Jeffers, defendants, and Houston American Energy Corp., as nominal defendant, Case No. 4:12

shareholder on behalf of Houston American against certain of our directors and senior executive officers in connection with the June 11, 2012 approval of payment of certain bonuses, increases

in salary, grant of certain stock options and entry into certain Change in Control Agreements. The complaint alleges that the approval of such matters constituted breach of fiduciary duty and

corporate waste and seeks injunctive relief to bar each of the actions in question and seeks restitution. No damages have been or, by the nature of the derivative cause of action, are expected to

be alleged against us. On February 26, 2013, an order was entered granting a motion by the Company to dismiss the lawsuit and providing leave to the plaintiff to amend its complaint to cure

pleading deficiencies. The Plaintiff ’ s allotted time to amend its complaint by the Court expired on March 26, 2013, and no amendment was made by the Plaintiff, effectively ending the lawsuit.

At December 31, 2012, the Company was the subject of a formal investigation being conducted by the Securities and Exchange Commission (the “ SEC ” ). Pursuant to the investigation, the

Company received subpoenas issued by the SEC. The subpoenas called for the testimony of certain of the Company ’ s officers and the delivery of certain documents. The subpoenas were

issued pursuant to a nonpublic formal order of private investigation issued by the SEC on March 1, 2011, which followed a nonpublic informal inquiry commenced by the SEC in October 2010.

there have been any violations of the federal securities laws and appears to have narrowed the focus of their investigation to matters relating to disclosures in the late 2009 and early 2010 time

period regarding resource potential for the CPO 4 prospect. The Company has presented information supporting its disclosure relative to resource potential on the CPO 4 prospect. The

investigation does not represent a conclusion by the staff that there have been any violations of the federal securities laws nor whether the staff would conclude that any enforcement action is

appropriate. At this time, the Company has not been made aware of a finding by the SEC of any securities violations. Also, as stated in the subpoenas issued by the SEC, the investigation does

not mean that the SEC has a negative opinion of any person, entity or security. The Company has cooperated fully, and is committed to continuing to cooperate fully, with the SEC in this matter.

It is not possible at this time to predict the timing or outcome of the SEC investigation, including whether or when any proceedings might be initiated, when these matters may be resolved or

what, if any, penalties or other remedies may be imposed, and whether any such penalties or remedies would have a material adverse effect on the Company ’ s consolidated financial position,

results of operations, or cash flows.

Item 6. Selected Financial Data

25General

We are an independent energy company focused on the development, exploration, exploitation, acquisition, and production of natural gas and crude oil properties in the U.S. Gulf Coast

region and in South America. Our oil and gas reserves and operations are concentrated primarily in the South American country of Colombia and in the onshore Gulf Coast region, particularly

Texas and Louisiana.

Our mission is to deliver outstanding net asset value per share growth to our investors via attractive oil and gas investments. Our strategy is to focus on early identification of, and

entrance into, existing and emerging resource plays, particularly in South America and the U.S. Gulf Coast. We typically seek to partner with larger operators in development of resources or

retain interests, with or without contribution on our part, in prospects identified, packaged and promoted to larger operators. By entering these plays earlier and partnering with, or promoting to,

larger operators, we believe we can capture larger resource potential at lower cost and minimize our exposure to drilling risks and costs and ongoing operating costs.

We, along with our partners, actively manage our resources through opportunistic acquisitions and divestitures where reserves can be identified, developed, monetized and financial

resources redeployed with the objective of growing reserves, production and shareholder value.

Generally, we generate nearly all our revenues and cash flows from the sale of produced natural gas and crude oil, whether through royalty interests, working interests or other

arrangements. We may also realize gains and additional cash flows from the periodic divestiture of assets.

Recent Developments

Drilling Activity

During 2012, we drilled 5 international wells in Colombia, as follows:

At December 31, 2012, no wells were being drilled.

During 2012, no domestic wells were drilled.

Sale of La Cuerva and LLA 62 Blocks

During the first quarter of 2012, we sold all of our interest in Hupecol Cuerva, LLC ( “ HC, LLC ” ), which holds interests in the La Cuerva block and, pending approval of the Colombian

authorities, the LLA 62 block, together covering approximately 90,000 acres in the Llanos Basin in Colombia.

HC, LLC sold for $75 million, adjusted for working capital. 13.3% of the sales price of HC, LLC will be held in escrow to fund potential claims arising from the sale. Pursuant to our 1.6%

ownership interest in HC, LLC, we received 1.6% in the net sale proceeds after deduction of commissions, overriding royalty interest, and transaction expenses; subject to the escrow holdback

and a further contingency holdback by Hupecol of 1.3% of the sales price. Following completion of the sale of HC, LLC, we have no continuing interest in the La Cuerva and LLA 62 blocks.

At December 31, 2011, our estimated proved reserves associated with the La Cuerva and LLA 62 blocks totaled 94,619 barrels of oil, which represented 82% of our estimated proved oil and

natural gas reserves. Sales of oil and gas properties under the full cost method of accounting are accounted for as adjustments of capitalized costs with no gain or loss recognized, unless the

adjustment significantly alters the relationship between capitalized costs and reserves. Since the sale of these oil and gas properties would significantly alter the relationship, we recognized a

gain on the sale of $315,119 during 2012, computed as follows: Filer: Houston American Energy Corp Form Type: 10

Item 7. Management ’ s Discussion and Analysis of Financial Condition and Results of Operations

● 2 wells were drilled on the La Cuerva concession in which we hold a 1.6% working interest, of which 2 were completed and brought onto production (both wells were sold in

connection with the sale of our interest in HC, LLC. See “ Sale of La Cuerva and LLA 62 Blocks ” ).

● 3 wells were drilled on the CPO 4 block in Colombia, each of which was determined to be non

- commercial.

26The following table presents pro forma data that reflects revenue, income from continuing operations, net loss and loss per common share for 2011 and 2012 as if the HC, LLC sale had

occurred at the beginning of each period and excludes the gain on sale.

2012 Capital Expenditure Program

During 2012, we invested $26,033,065 for the development of oil and gas properties, consisting of (1) drilling and drilling preparation costs on 5 wells in Colombia of $25,915,741 and

leasehold costs on U.S. properties of $117,324.

CPO 4 Developments

During 2012, we completed operations on three test wells on our CPO 4 block in Colombia. Each of the test wells was determined to be noncommercial and was plugged and

abandoned. As a result of the determinations to plug and abandon each of those test wells, we included the costs related to those wells in the full cost pool for inclusion in the ceiling test. We

recorded an impairment charge of $46,235,574 during 2012 to write off costs not being amortized that were attributable to the drilling of the test wells on the CPO 4 block as well as to write off

seismic exploration and evaluation cost, general and administrative cost and environmental and governmental cost that were attributable to the test wells through December 31, 2012.

Following drilling of the unsuccessful test wells on the CPO 4 prospect, in March 2013, we entered into a settlement agreement with SK Innovation, operator of the CPO 4 prospect, and

terminated our interest in the prospect and were released from past and future funding and other obligations relating to the prospect, including our accrued cash call commitments of $3,219,128.

Serrania Developments

With respect to development of our Serrania Block, the National Hydrocarbon Agency of Colombia (the “ ANH ” ) has granted extensions of required development commitments, including

drilling of a first test well, until security conditions allow operations. Based on those conditions, we anticipate that drilling of a first test well on the Serrania Block will occur in 2013.

Gulf United Note Receivable

As a result of Gulf United Energy ’ s delinquency in satisfying its financial obligations with respect to the CPO 4 prospect, during 2012, we wrote

27Financing Activities

On May 8, 2012, we sold to institutional investors 6,200,000 units, with each unit consisting of one of our common shares and one warrant to purchase one common share, for gross

proceeds of approximately $13.14 million, before deducting placement agent fees and estimated offering expenses of $527,000 recorded as cost of capital, in a "registered direct" offering. The

investors purchased the units at a purchase price of $2.12 per unit. The warrants, which represent the right to acquire an aggregate of up to 6,200,000 common shares, are exercisable at any time

on or after November 9, 2012 and prior to November 9, 2015 at an exercise price of $2.68 per share, which was 120% of the closing price of our common shares on the NYSE MKT on May 2, 2012.

On October 4, 2012, we sold 14,814,815 units, with each unit consisting of one of our common shares, one Class A Warrant and one Class B Warrant, for gross proceeds of approximately

$10.0 million, before deducting placement agent fees and estimated offering expenses of $828,000 recorded as cost of capital, in a "registered direct" public offering. The investors purchased the

units at a purchase price of $0.675 per unit. The Class A Warrants represent the right to acquire one

- half common share per warrant, or an aggregate of up to 7,407,407 common shares for a

period of six months at an exercise price of $0.81 per share. The Class B Warrants represent the right to acquire one

- half common share per warrant, or an aggregate of up to 7,407,407 common

shares for a period of three years at an exercise price of $0.90 per share.

Legal Proceedings

At December 31, 2012, we were the subject of a formal investigation being conducted by the Securities and Exchange Commission (the “ SEC ” ). Pursuant to the investigation, we received

subpoenas issued by the SEC. The subpoenas called for the testimony of certain of our officers and the delivery of certain documents. The subpoenas were issued pursuant to a nonpublic

formal order of private investigation issued by the SEC on March 1, 2011, which followed a nonpublic informal inquiry commenced by the SEC in October 2010. We received a copy of the

nonpublic formal order of private investigation on February 10, 2012 in connection with a subpoena issued by the SEC. The SEC is investigating whether there have been any violations of the

federal securities laws and appears to have narrowed the focus of their investigation to matters relating to disclosures in the late 2009 and early 2010 time period regarding resource potential for

the CPO 4 prospect. We have presented information supporting our disclosure relative to resource potential on the CPO 4 prospect. The investigation does not represent a conclusion by the

staff that there have been any violations of the federal securities laws nor whether the staff would conclude that any enforcement action is appropriate. At this time, we have not been made

aware of a finding by the SEC of any securities violations. Also, as stated in the subpoenas issued by the SEC, the investigation does not mean that the SEC has a negative opinion of any

person, entity or security. We have cooperated fully, and are committed to continuing to cooperate fully, with the SEC in this matter. It is not possible at this time to predict the timing or outcome

of the SEC investigation, including whether or when any proceedings might be initiated, when these matters may be resolved or what, if any, penalties or other remedies may be imposed, and

whether any such penalties or remedies would have a material adverse effect on our consolidated financial position, results of operations, or cash flows.

In connection with the ongoing investigation being conducted by the SEC and indemnification provisions contained in an engagement agreement with Global Hunter Securities, LLC

relating to our 2009 equity offering, in July 2012, we entered into an agreement with Global Hunter to settle any and all claims by Global Hunter related to reimbursement of attorney ’ s fees under

the indemnity provision. During 2012, we paid a total of $490,850 to Global Hunter and in exchange for the payments, we were granted a full release by Global Hunter Securities of any future

claims or liabilities asserted by Global Hunter in connection with the offering. The payment to Global Hunter Securities was recorded as a charge to additional paid in capital and is listed under

the Cash Flow from Financing Activities in the statement of cash flows as Cost of capital.

On April 27, 2012, a purported class action lawsuit was filed in the U.S. District Court for the Southern District of Texas against us and certain of our executive officers: Steve Silverman v.

Houston American Energy Corp. et al ., Case No. 4:12

- CV

- 1332. The complaint generally alleges that, between March 29, 2010 and April 18, 2012, all of the defendants violated Sections 10(b) of

the Securities Exchange Act of 1934 and SEC Rule 10b

- 5 and the individual defendants violated Section 20(a) of the Exchange Act in making materially false and misleading statements including

certain statements related to the status and viability of the Tamandua #1 well. Two additional class action lawsuits were filed against us in May 2012. The complaints seek unspecified damages,

interest, attorneys ’ fees, and other costs. On September 20, 2012, the court consolidated the class action lawsuits and appointed a lead plaintiff. We believe all of the claims in the consolidated

class action lawsuits are without merit and intend to vigorously defend against these claims. It is not possible at this time to predict the timing or outcome of the class action lawsuits that have or

may be filed. We expect to incur costs and to devote management time and resources to defending such lawsuits. Filer: Houston American Energy Corp Form Type: 10

28On July 19, 2012, a purported derivative cause of action was filed in the U.S. District Court for the Southern District of Texas against certain of our directors and officers and Houston

American Energy, as nominal defendant: E. Howard King, Jr., derivatively, on behalf of Houston American Energy Corp., v. John F. Terwilliger, John P. Boylan, Orrie Lee Tawes III, Stephen

Hartzell, James J. Jacobs, Kenneth A. Jeffers, defendants, and Houston American Energy Corp., as nominal defendant, Case No. 4:12

- CV

- 02182. The complaint asserts a cause of action by a

shareholder on behalf of Houston American against certain of our directors and senior executive officers in connection with the June 11, 2012 approval of payment of certain bonuses, increases

in salary, grant of certain stock options and entry into certain Change in Control Agreements. The complaint alleges that the approval of such matters constituted breach of fiduciary duty and

corporate waste and seeks injunctive relief to bar each of the actions in question and seeks restitution. No damages have been or, by the nature of the derivative cause of action, are expected to

be alleged against us. We may, however, incur certain costs and demands on management time and resources in connection with the lawsuit. On February 26, 2013, an order was entered

granting a motion by the company to dismiss the lawsuit and providing leave to the plaintiff to amend its complaint to cure pleading deficiencies.

Compensation Expense

In June 2012, our board of directors approved, and we paid, cash bonuses to our senior management team totaling $403,199 and grants of stock options to acquire an aggregate of

1,200,000 shares of common stock and, effective July 1, 2012, we increased the base salary of members of our senior management team by amounts ranging from 5% to 15%.

The options granted vested on the grant date, have a ten year life and have an exercise price of $1.65 per share. Of those options, 429,000 are exercisable commencing 6 months from the

date of grant and 771,000 are exercisable on and after shareholder approval of an amendment to our 2008 Equity Incentive Plan to increase the shares reserved under the plan to facilitate exercise.

The option grants to employees, excluding grants that are subject to shareholder approval of amendment to the 2008 Equity Incentive Plan, were valued on the date of grant at $354,098 using the

Black

- Scholes option

- pricing model. Of that value, all were recognized as compensation expense at the date of grant. Option grants that remain subject to shareholder approval of amendment to

the 2008 Equity Incentive Plan will be valued and accounted for at the time of shareholder approval of the amendment.

In June 2012, our board of directors approved grants of stock options to purchase 25,000 shares of common stock, consistent with our existing director compensation program, to each of

our non

- employee directors and one

- time extraordinary grants of stock options to purchase 75,000 shares of common stock to each of our non

- employee directors. Each of the options vest 20%

on the grant date and 80% nine months from the grant date and is exercisable for a term of 10 years at an exercise price of $1.65 per share; provided, however, that 48,175 of the options granted to

each of the directors shall not be exercisable, in part or in whole, until such time as our shareholders shall have approved an amendment to our 2008 Equity Incentive Plan increasing the shares

reserved for issuance under the plan to an amount sufficient to permit issuance of such shares. The option grants to non

- employee directors, excluding grants that are subject to shareholder

approval of amendment to the 2008 Equity Incentive Plan, were valued on the date of grant at $128,328 using the Black

- Scholes option

- pricing model. Of that value, $25,665 was recognized as

compensation expense at the date of grant and $102,663 will be recognized upon vesting.

In June 2012, our board of directors amended our cash compensation arrangements for non

- employee directors, effective June 30, 2012, to increase all amounts payable thereunder by 50%

to: annual retainer of $9,000; annual retainer for service on each committee of $3,000; annual retainer for service as chairman of the audit committee of $3,750; and annual retainer for service as

chairman of the compensation committee of $2,250.

In June 2012, our board of directors approved the entry into Change in Control Agreements (the “ Change in Control Agreements ” ) with our President and Chief Executive Officer, John

Terwilliger, Chief Financial Officer, James J. Jacobs, and Senior Vice President

– Exploration, Kenneth Jeffers. Pursuant to the Change in Control Agreements, if we undergo a change in control

and a covered officer is terminated without cause or resigns for good reason within 90 days prior to or within 12 months following a change in control, the subject officer is entitled to (i) a lump

sum cash severance payment equal to 250% of his average annual cash compensation (including salary and bonuses) during the three years ending on the termination date, and (ii) acceleration

29In July 2012, we appointed a new non

- employee director following the resignation of a non

- employee director. In connection with the appointment, we granted stock options to purchase

25,000 shares of common stock at $1.18 per share with a fair value of $19,375 using the Black

- Scholes option

- pricing model. Of that value, $5,572 was recognized as compensation expense at the

date of grant and $13,803 will be recognized upon vesting.

During 2012, we recognized non

- cash compensation expense associated with grants of restricted stock totaling $226,440.

As of December 31, 2012, excluding grants that remain subject to shareholder approval of amendment to the 2008 Equity Incentive Plan, there was $358,055 of total unrecognized

compensation cost related to unvested restricted stock and $1,300,747 of total unrecognized compensation cost related to unvested, or un

- exercisable, stock options. The cost is expected to be

recognized over a weighted average period of approximately 1.45 years for restricted stock and 1.27 years for stock options. Option grants that remain subject to shareholder approval of

amendment to the 2008 Equity Incentive Plan will be valued and accounted for at the time of shareholder approval of the amendment.

Strategic Alternative Review

In July 2012, our board authorized the engagement of an investment banking firm, and we engaged Canaccord Genuity, Inc., to assist in the evaluation of a broad range of financial and

strategic alternatives, including, but not limited to, seeking additional financing to support the long

- term development of our oil and gas properties, seeking financial and/or industry partners to

participate in the development of our properties, selling some of or all of our assets or interests in those assets, and the possible sale of our company, among other alternatives. Our board

concluded the review of strategic alternatives determining that satisfactory alternatives were not available and that we should seek additional financing to support the ongoing development of

our assets. Following that determination, we consummated the October 1, 2012 financing described above.

Colombian Tax

During 2012, we engaged our tax advisors in Colombia to evaluate certain tax and other filings made in Colombia by them and other advisors for 2009, 2010 and 2011. Our advisors

identified inconsistencies between tax and non

- tax filings with respect to equity investments made by us in Colombia. Based on guidance from our advisors, during 2012 we recorded a current

foreign tax liability of $1,689,868, which we expect to pay during 2013, and a non

- current foreign tax liability of $193,398, which we expect to pay during 2014, relating primarily to a newly enacted

Colombian equity tax measure based on the equity of our Colombian branch as of January 1, 2011.

Critical Accounting Policies

The following describes the critical accounting policies used in reporting our financial condition and results of operations. In some cases, accounting standards allow more than one

alternative accounting method for reporting. Such is the case with accounting for oil and gas activities described below. In those cases, our reported results of operations would be different

should we employ an alternative accounting method.

Full Cost Method of Accounting for Oil and Gas Activities. We follow the full cost method of accounting for oil and gas property acquisition, exploration and development activities.

Under this method, all productive and nonproductive costs incurred in connection with the exploration for and development of oil and gas reserves are capitalized. Capitalized costs include lease

acquisition, geological and geophysical work, delay rentals, costs of drilling, completing and equipping successful and unsuccessful oil and gas wells and related internal costs that can be

directly identified with acquisition, exploration and development activities, but does not include any cost related to production, general corporate overhead or similar activities. Gain or loss on

the sale or other disposition of oil and gas properties is not recognized unless significant amounts of oil and gas reserves are involved. No corporate overhead has been capitalized as of

December 31, 2012. The capitalized costs of oil and gas properties, plus estimated future development costs relating to proved reserves, are amortized on a units

- of

- production method over the

estimated productive life of the reserves. Unevaluated oil and gas properties are excluded from this calculation. The capitalized oil and gas property costs, less accumulated amortization, are

limited to an amount (the ceiling limitation) equal to the sum of: (a) the present value of estimated future net revenues from the projected production of proved oil and gas reserves, calculated

using the average oil and natural gas sales price received by the Company as of the first trading day of each month over the preceding twelve months (such prices are held constant throughout

the life of the properties) and a discount factor of 10%; (b) the cost of unproved and unevaluated properties excluded from the costs being amortized; (c) the lower of cost or estimated fair value

of unproved properties included in the costs being amortized; and (d) related income tax effects. Costs in excess of this ceiling are charged to proved properties impairment expense. Filer: Houston American Energy Corp Form Type: 10

30Unevaluated Oil and Gas Properties. Unevaluated oil and gas properties consist principally of our cost of acquiring and evaluating undeveloped leases, net of an allowance for

impairment and transfers to depletable oil and gas properties. When leases are developed, expire or are abandoned, the related costs are transferred from unevaluated oil and gas properties to oil

and gas properties subject to amortization. Additionally, we review the carrying costs of unevaluated oil and gas properties for the purpose of determining probable future lease expirations and

abandonments, and prospective discounted future economic benefit attributable to the leases.

Unevaluated oil and gas properties not subject to amortization include the following at December 31, 2012 and 2011:

The carrying value of unevaluated oil and gas prospects includes $4,836,412 and $22,028,895 expended for properties in South America at December 31, 2012 and December 31, 2011,

respectively. We are maintaining our interest in these properties and development has or is anticipated to commence within the next twelve months.

- pricing model, which requires the input of highly subjective assumptions. These assumptions include estimating the

volatility of our common stock price over the expected life of the options, dividend yield, an appropriate risk

- free interest rate and the number of options that will ultimately not complete their

vesting requirements. Changes in the subjective assumptions can materially affect the estimated fair value of stock

- based compensation and consequently, the related amount recognized on the

Statements of Operations.

Results of Operations

Year Ended December 31, 2012 Compared to Year Ended December 31, 2011

Oil and Gas Revenues . Total oil and gas revenues decreased 64.4%, to $411,349, in 2012 from $1,156,178 in 2011.

The decrease in revenue was due to the 2012 sale of our interest in the La Cuerva block.

The following table sets forth the gross and net producing wells, net oil and gas production volumes and average hydrocarbon sales prices for 2012 and 2011:

The change in gross and net producing wells and production reflects the sale, during the first quarter of 2012, of our interest in wells associated with the La Cuerva block.

The change in average sales prices realized reflects fluctuations in global commodity prices. Filer: Houston American Energy Corp Form Type: 10

31Oil and gas sales revenues for 2012 and 2011 by region were as follows:

Lease Operating Expenses. Lease operating expenses, excluding joint venture expenses relating to our Colombian operations discussed below, decreased 77.1% to $195,381 in 2012 from

$854,319 in 2011.

The decrease in total lease operating expenses was attributable to the 2012 sale of our interest in the La Cuerva block.

Following is a summary comparison of lease operating expenses for the periods.

Consistent with our business model and operating history, we experience steep declines in lease operating expenses following strategic divestitures and anticipate lease operating

expenses to ramp up to levels consistent with regional costs as new wells are brought on line.

Joint Venture Expenses . Joint venture expenses totaled $3,244 in 2012 compared to $13,930 in 2011. The joint venture expenses represent our allocable share of the indirect field operating

and region administrative expenses billed by Hupecol. The decrease in joint venture expenses was attributable to reduced allocated administrative costs following the March 2012 divestiture of

assets operated by Hupecol.

Depreciation and Depletion Expense. Depreciation and depletion expense decreased by 64% to $66,971 in 2012 from $185,931 in 2011. The decrease in depreciation and depletion was due

to the 2012 sale of assets discussed above.

Gain (Loss) on Sale of Oil and Gas Properties. The sale of our indirect interests in Hupecol Cuerva, LLC and post

- closing price adjustments related to the sale resulted in a gain of

$387,314 during 2012. Post

- closing purchase price adjustments relating to our 2010 sale of Colombian assets and our prior 2008 sale of Colombian assets resulted in a loss on sale of oil and gas

properties of $1,026,608 in 2011.

Impairment Expense . Termination of our testing and completion efforts on, and abandonment of, three test wells on our CPO 4 block resulted in impairment expense of $46,235,574 during

2012.

General and Administrative Expenses. General and administrative expense increased by 1.5% to $5,027,024 in 2012 from $4,952,560 in 2011. The change in general and administrative

expense reflects a combination of (1) an increase in legal fees and professional fees (up $426,636) relating to litigation commenced during 2012 and the ongoing SEC investigation, (2) a decrease

in non

- cash stock based compensation (down $319,719) reflecting lower stock price and a resulting lower value of equity grants, and (3) decreased cash compensation (down $66,093) attributable

to reduced bonuses paid during 2012.

Bad Debt Expense. As a result of Gulf United Energy ’ s delinquency in satisfying its financial obligations with respect to the CPO 4 prospect, during 2012, we wrote

- down our receivable

from Gulf United for $3,951,370.

Foreign Equity Tax

. During 2012, we recorded an foreign equity tax expense of $1,689,039 relating to a newly enacted Colombian equity tax measure based on the equity of our Colombian

branch as of January 1, 2011.

Other Income (Expense) . Other income (expense) consists of interest earned on cash balances net of other bank fees. Net other expense totaled $73,319 in 2012 as compared to net other

expense of $29,020 in 2011. The change was attributable to reduced interest income during 2012 reflecting lower interest rates and lower cash holdings. Filer: Houston American Energy Corp Form Type: 10

32Income Tax Expense/Benefit

. We reported income tax expense of approximately $216,923 in 2012 as compared to an income tax benefit of approximately $1.6 million in 2011. During 2012,

we generated net operating losses, from which a current benefit in the amount of $3.4 million was realized as a result of carrying back the respective net operating losses to 2010. The current tax

benefit was entirely offset by the release in the valuation allowance. We expect a refund of U.S. income taxes in the amount of approximately $3.4 million as a result of such net operating loss

carryback. Except for this tax benefit, we believe that it is more likely than not that the deferred tax assets at the end of 2012 will not be realized. As such, we fully reserved all of the net deferred

tax assets at December 31, 2012.

Financial Condition

Liquidity and Capital Resources. At December 31, 2012, we had a cash balance of $5,626,345 and working capital of $9,144,869 compared to a cash balance of $9,930,284 and working

capital of $19,636,540 at December 31, 2011. The decrease in cash and working capital during 2012 was primarily attributable to the operating losses incurred during 2012, including the costs of

drilling operations on the CPO 4 block which were written off during 2012, partially offset by the receipt of approximately $23,144,000 from capital raising transactions during 2012. As a result of

our settlement with SK Innovation, subsequent to year

- end, we received a release from our accrued capital call commitments on CPO 4 which totaled $3,219,128 at December 31, 2012. As

adjusted to reflect the release of such commitments, our pro forma working capital at December 31, 2012 totaled $12,363,997.

Cash Flows . Operating activities used $2,620,837 of cash during 2012 compared to $4,633,032 of cash used during 2011. The decrease in cash used in operations was primarily attributable

to changes in operating assets and liabilities and various non

- cash expenses which more than offset the increase in net loss.

Investing activities used $23,041,556 of cash during 2012 as compared to $11,930,534 of cash used during 2011. Funds used in investing activities during 2012 principally reflect

investments in oil and gas properties and assets of $26,033,065 and purchases of marketable securities of $156,817 partially offset by proceeds from sale of securities of $660,625, escrow

receivable of $1,460,633 and proceeds from the sale of our interest in Hupecol Cuerva, LLC of $1,027,068.

Financing activities provided $21,358,454 of cash during 2012 from our May 2012 and October 2012 offerings of common stock and warrants.

Long

- Term Liabilities. At December 31, 2012, we had long

- term liabilities of $201,270 as compared to $45,039 at December 31, 2011. Long

- term liabilities at December 31, 2012 consisted of

reserve for plugging costs $7,872 and foreign income taxes of $193,398. Long

- term liabilities at December 31, 2011 consisted of a reserve for plugging costs and deferred rent liability.

Capital and Exploration Expenditures and Commitments. Our principal capital and exploration expenditures relate to our ongoing efforts to acquire, drill and complete prospects.

During 2012, we invested $26,033,065 for the acquisition and development of oil and gas properties, which included expenses related to (1) drilling of 5 wells in Colombia ($25,915,741),

including the drilling costs on two wells on the La Cuerva block sold during 2012, as well as leasehold costs on U.S. properties ($117,324).

At December 31, 2012, our only material contractual obligation requiring determinable future payments on our part was our lease relating to our executive offices.

The following table details our contractual obligations as of December 31, 2012:

In addition to the contractual obligations requiring that we make fixed payments, in conjunction with our efforts to secure oil and gas prospects, financing and services, we have, from time

to time, granted overriding royalty interests (ORRI) in various properties, and may grant ORRIs in the future, pursuant to which we will be obligated to pay a portion of our interest in revenues

from various prospects to third parties. All present and future prospects in Colombia are subject to a 1.5% ORRI in favor of each of John Terwilliger and O. Lee Tawes, III.

Planned Drilling, Leasehold and Other Activities. As of December 31, 2012, our acquisition and drilling budget for 2013 totaled approximately $2.5 million and related principally to (1)

drilling 2 wells on the Serrania Block; and (2) shooting seismic on the Los Picachos and Macaya Concessions. Additional wells may be drilled at locations to be determined based on the results

of the planned drilling projects. Our acquisition and drilling budget has historically been subject to substantial fluctuation over the course of a year based upon successes and failures in drilling

and completion of prospects and the identification of additional prospects during the course of a year. Filer: Houston American Energy Corp Form Type: 10

such financing and there is no guarantee that we will be able to secure additional financing on acceptable terms, or at all, if necessary to fully fund our 2013 drilling budget and to support future

acquisitions and development activities.

Off

- Balance Sheet Arrangements

We had no off

- balance sheet arrangements or guarantees of third party obligations at December 31, 2012.

Inflation

We believe that inflation has not had a significant impact on our operations since inception.

Commodity Price Risk

The price we receive for our oil and gas production heavily influences our revenue, profitability, access to capital and future rate of growth. Crude oil and natural gas are commodities and,

therefore, their prices are subject to wide fluctuations in response to relatively minor changes in supply and demand. Historically, the markets for oil and gas have been volatile, and these

markets will likely continue to be volatile in the future. The prices we receive for production depends on numerous factors beyond our control.

We have not historically entered into any hedges or other derivative commodity instruments or transactions designed to manage, or limit exposure to oil and gas price volatility.

To the Board of Directors and Shareholders

Houston American Energy Corp.

Houston, Texas

We have audited the accompanying consolidated balance sheets of Houston American Energy Corp. (the “ Company ” ) as of December 31, 2012 and 2011, and the related consolidated statements

of operations and comprehensive income, changes in shareholders ’ equity, and cash flows for the years ended December 31, 2012 and 2011. These consolidated financial statements are the

responsibility of the Company ’ s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to

obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the

amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as

evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Houston American Energy Corp. as of December 31, 2012

and 2011, and the results of their operations and their cash flows for the years ended December 31, 2012 and 2011, in conformity with accounting principles generally accepted in the United

States of America. Filer: Houston American Energy Corp Form Type: 10

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1

— NATURE OF COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

General

Houston American Energy Corp. (a Delaware Corporation) ( “ the Company ” or “ HUSA ” ) was incorporated on April 2, 2001. The Company is engaged, as a non

- operating joint owner, in

the exploration, development, and production of natural gas, crude oil, and condensate from properties located principally in the Gulf Coast area of the United States and international locations

with proven production, which to date has focused on Colombia, South America.

Consolidation

The accompanying consolidated financial statements include all accounts of HUSA and its subsidiaries (HAEC Louisiana E&P, Inc. and HAEC Caddo Lake E&P, Inc.). All significant inter

company balances and transactions have been eliminated in consolidation.

General Principles and Use of Estimates

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. In preparing financial statements,

management makes informed judgments and estimates that affect the reported amounts of assets and liabilities as of the date of the financial statements and affect the reported amounts of

revenues and expenses during the reporting period. On an ongoing basis, management reviews its estimates, including those related to such potential matters as litigation, environmental

liabilities, income taxes, and determination of proved reserves of oil and gas and asset retirement obligations. Changes in facts and circumstances may result in revised estimates and actual

results may differ from these estimates.

Reclassification

Certain amounts for prior periods have been reclassified to conform to the current presentation.

Cash and Cash Equivalents

Cash and cash equivalents consist of demand deposits and cash investments with initial maturity dates of less than three months.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk include cash and cash equivalents. The Company had cash deposits of approximately $8.3

million in excess of the FDIC ’ s current insured limit of $250,000 at December 31, 2012 for interest bearing accounts. The Company has not experienced any losses on its deposits of cash and cash

equivalents.

Marketable Securities

– Available for Sale

Management determines the appropriate classification of its investments in marketable securities at the time of purchase and reevaluates such determination at each balance sheet

date. Equity securities not classified as trading securities are classified as available

- for

- sale. Available

- for

- sale securities are reported at fair value and unrealized gains and losses are included in

stockholders' equity. Management determines fair value of its investments based on quoted market prices at each balance sheet date.

Accounts Receivable

Accounts receivable

– other and escrow receivables have been evaluated for collectability and are recorded at their net realizable values. Filer: Houston American Energy Corp Form Type: 10

- 7Allowance for Accounts Receivable

The Company regularly reviews outstanding receivables and provides for estimated losses through an allowance for doubtful accounts when necessary. In evaluating the need for an

allowance, the Company makes judgments regarding its customers' ability to make required payments, economic events and other factors. As the financial condition of these parties change,

circumstances develop or additional information becomes available, an allowance for doubtful accounts may be required. When the Company determines that a customer may not be able to make

required payments, the Company increases the allowance through a charge to income in the period in which that determination is made. As of December 31, 2012, the Company evaluated their

receivables and determined an allowance was not required.

Oil and Gas Revenues

The Company recognizes sales revenues, net of royalties and net profits interests, based on the amount of gas, oil, and condensate sold to purchasers when delivery to the purchaser has

occurred and title has transferred. This occurs when production has been delivered to a pipeline. The Company follows the sales method to account for natural gas imbalances. Sales may result

in more or less of the Company ’ s share of pro

- rata production from certain wells. When natural gas sales volumes exceeds the Company ’ s entitled share and the accumulated overproduced

balance exceeds the Company ’ s share of the remaining estimated proved natural gas reserves for a given property, the Company will record a liability. Historically, sales volumes have not

materially differed from the Company ’ s entitled share of natural gas production and the Company did not have a material imbalance position in terms of volumes or values at December 31, 2012 or

2011.

Oil and Gas Properties

The Company uses the full cost method of accounting for exploration and development activities as defined by the SEC. Under this method of accounting, the costs for unsuccessful, as

well as successful, exploration and development activities are capitalized as oil and gas properties. Capitalized costs include lease acquisition, geological and geophysical work, delay rentals,

costs of drilling, completing and equipping the wells and any internal costs that are directly related to acquisition, exploration and development activities but does not include any costs related

to production, general corporate overhead or similar activities. Proceeds from the sale or other disposition of oil and gas properties are generally treated as a reduction in the capitalized costs of

oil and gas properties, unless the impact of such a reduction would significantly alter the relationship between capitalized costs and proved reserves of oil and natural gas attributable to a

country.

The Company categorizes its full cost pools as costs subject to amortization and costs not being amortized. The sum of net capitalized costs subject to amortization, including estimated

future development and abandonment costs, are amortized using the unit

- of

- production method. Depletion and amortization for oil and gas properties was $49,391 and $168,351 for the years

ended December 31, 2012 and 2011, respectively and accumulated amortization, depreciation and impairment was $47,043,262 and $1,630,323 at December 31, 2012 and 2011, respectively.

Costs Excluded

Oil and gas properties include costs that are excluded from capitalized costs being amortized. These amounts represent costs of investments in unproved properties. The Company

excludes these costs on a country

- by

- country basis until proved reserves are found or until it is determined that the costs are impaired. All costs excluded are reviewed quarterly to determine if

impairment has occurred. The amount of any impairment is transferred to the costs subject to amortization.

Ceiling Test

Under the full cost method of accounting, a ceiling test is performed each quarter. The full cost ceiling test is an impairment test prescribed by SEC Regulation S

- X. The ceiling test

determines a limit, on a country

- by

- country basis, on the book value of oil and gas properties. The capitalized costs of proved oil and gas properties, net of accumulated depreciation, depletion,

amortization and impairment ( “ DD&A ” ) and the related deferred income taxes, may not exceed the estimated future net cash flows from proved oil and gas reserves, calculated for 2012 using the

average oil and natural gas sales price received by the Company as of the first trading day of each month over the preceding twelve months (such prices are held constant throughout the life of

the properties) with consideration of price change only to the extent provided by contractual arrangement, discounted at 10%, net of related tax effects. If capitalized costs exceed this limit, the

excess is charged to expense and reflected as additional accumulated DD&A. Filer: Houston American Energy Corp Form Type: 10

- 8Furniture and Equipment

Office equipment is stated at original cost and is depreciated on the straight

- line basis over the useful life of the assets, which ranges from three to five years.

Depreciation expense for office equipment was $17,580 and $17,580 for 2012 and 2011, respectively, and accumulated depreciation was $62,489 and $44,909 at December 31, 2012 and 2011,

respectively.

Asset Retirement Obligations

For the Company, asset retirement obligations ( “ ARO ” ) represent the systematic, monthly accretion and depreciation of future abandonment costs of tangible assets such as platforms,

wells, service assets, pipelines, and other facilities. The fair value of a liability for an asset ’ s retirement obligation is recorded in the period in which it is incurred if a reasonable estimate of fair

value can be made, and that the corresponding cost is capitalized as part of the carrying amount of the related long

- lived asset. The liability is accreted to its then present value each period, and

the capitalized cost is depreciated over the useful life of the related asset. If the liability is settled for an amount other than the recorded amount, an adjustment is made to the full cost pool, with

no gain or loss recognized, unless the adjustment would significantly alter the relationship between capitalized costs and proved reserves. Although the Company ’ s domestic policy with respect

to ARO is to assign depleted wells to a salvager for the assumption of abandonment obligations before the wells have reached their economic limits, the Company has estimated its future ARO

obligation with respect to its domestic operations. The ARO assets, which are carried on the balance sheet as part of the full cost pool, have been included in our amortization base for the

purposes of calculating depreciation, depletion and amortization expense. For the purposes of calculating the ceiling test, the future cash outflows associated with settling the ARO liability have

been included in the computation of the discounted present value of estimated future net revenues.

Joint Venture Expense

Joint venture expense reflects the indirect field operating and regional administrative expenses billed by the operator of the Colombian concessions.

Income Taxes

Deferred income taxes are provided on a liability method whereby deferred tax assets and liabilities are established for the difference between the financial reporting and income tax basis of

assets and liabilities as well as operating loss and tax credit carry forwards. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not

that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

Stock

- Based Compensation

The Company measures the cost of employee services received in exchange for stock and stock options based on the grant date fair value of the awards. The Company determines the fair

value of stock option grants using the Black

- Scholes option pricing model. The Company determines the fair value of shares of non

- vested stock based on the last quoted price of our stock on

the date of the share grant. The fair value determined represents the cost for the award and is recognized over the vesting period during which an employee is required to provide service in

exchange for the award. As share

- based compensation expense is recognized based on awards ultimately expected to vest, the Company reduces the expense for estimated forfeitures based on

historical forfeiture rates. Previously recognized compensation costs may be adjusted to reflect the actual forfeiture rate for the entire award at the end of the vesting period. Excess tax benefits, if

any, are recognized as an addition to paid

- in capital.

Preferred Stock

The Company has authorized 10,000,000 shares of preferred stock with a par value of $0.001. The Board of Directors shall determine the designations, rights, preferences, privileges and

voting rights of the preferred stock as well as any restrictions and qualifications thereon. No shares of preferred stock have been issued. Filer: Houston American Energy Corp Form Type: 10

- 9Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing the net income (loss) attributable to common shareholders by the weighted

- average number of common shares outstanding

during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) attributable to common shareholders by the weighted

- average number of common and

common equivalent shares outstanding during the period. Common share equivalents included in the diluted computation represent shares issuable upon assumed exercise of stock options and

warrants using the treasury stock and “ if converted ” method. For periods in which net losses are incurred, weighted average shares outstanding is the same for basic and diluted loss per share

calculations, as the inclusion of common share equivalents would have an anti

- dilutive effect.

For the year ended December 31, 2012, 2,443,057 outstanding options to purchase common stock were excluded from the calculation of diluted net loss per share because they were anti

dilutive. For the year ended December 31, 2011, 1,833,682 outstanding options to purchase common stock were excluded from the calculation of diluted net loss per share because they were anti

dilutive.

Concentration of Risk

The Company is dependent upon the industry skills and contacts of John F. Terwilliger, Ken Jeffers, and James J. Jacobs, the chief executive officer, senior vice president of exploration

and chief financial officer, respectively, to identify potential acquisition targets in the onshore coastal Gulf of Mexico region of Texas and Louisiana and in the South American country of

Colombia. Further, as a non

- operator oil and gas exploration and production company, and through its interest in a limited liability company ( “ Hupecol ” ) and concessions operated by Hupecol in

the South American country of Colombia, the Company is dependent on the personnel, management and resources of Hupecol to operate efficiently and effectively.

As a non

- operating joint interest owner, the Company has a right of investment refusal on specific projects and the right to examine and contest its division of costs and revenues

determined by the operator.

The Company currently has interests in concessions in Colombia and expects to be active in Colombia for the foreseeable future. The political climate in Colombia is unstable and could be

subject to radical change over a very short period of time. In the event of a significant negative change in political and economic stability in the vicinity of the Company ’ s Colombian operations,

the Company may be forced to abandon or suspend its efforts. Either of such events could be harmful to the Company ’ s expected business prospects.

At December 31, 2012, 96.5% of the Company ’ s net oil and gas property investment, and 64% of its revenue for the year ended December 31, 2012, was with or derived from interests

operated in Colombia.

For 2012, 100% of our oil production from the Company ’ s mineral interests was sold to an international integrated oil company. The gas production is sold to U.S. natural gas marketing

In June 2008, the Company, through Hupecol Caracara LLC as owner/operator under the Caracara Association Contract, sold all of its interest in the Caracara Association Contract and

related assets for a total cash consideration of $11,917,418.

Pursuant to the terms of the sale of the Caracara assets, on the closing date of the sale, a portion of the purchase price was deposited in escrow to settle post

- closing adjustments under

the purchase and sale agreement. The Company ’ s proportionate interest in the escrow deposit totaled $1,673,551, and was recorded as escrow receivable. During 2009, $1,158,613 of the funds

deposited in escrow was released to the Company based on post

- closing adjustments. During 2011, the Company was informed by Hupecol that approximately $136,430 of the Company ’ s funds

still held in escrow related to the Caracara sale will likely be used to pay a post

- closing settlement entered into between Hupecol and the purchaser of the Caracara assets. As such, during 2011,

the Company charged $136,430 to loss on sale of oil and gas properties on the income statement to account for the potential payment using the escrowed funds. During 2012, the Company

received $147,581 from Hupecol in settlement of the Caracara escrow and that account was closed.

Hupecol Dorotea and Cabiona, LLC and Hupecol Llanos, LLC Escrow

Pursuant to the terms of the sales of HDC, LLC and HL, LLC, on the closing date of the sale, a portion of the purchase price was deposited in escrow to settle post

- closing adjustments

under the purchase and sale agreement. The Company ’ s proportionate interest in the escrow deposit totaled $7,069,810, and was recorded as escrow receivable.

During 2011, the Company received a partial payment of $516,392 from Hupecol for the 5% contingency escrow related to HL, LLC, and was informed that Hupecol disbursed funds from

the 5% contingency escrow set up from the proceeds of the HDC, LLC sale to pay Colombian taxes as well as certain invoices related to post closing operating costs incurred on behalf of the

purchaser of these interests. Hupecol is currently seeking reimbursement from the purchaser for these expenses as part of the post

- closing process. As a result of this activity, the Company has

established a receivable from Hupecol for the Company ’ s proportionate share of the escrow funds disbursed for these expenses of $86,507 (See Note 2) and has reduced the 5% contingency

escrow account for HDC, LLC to reflect its current balance after payment of the taxes and post

- closing expenses paid on behalf of the purchaser.

In addition, during 2011, the Company received partial payments from the HL, LLC and HDC, LLC escrow accounts in the amounts of $474,786 and $508,717, respectively. The Company

was also informed that Hupecol made payments from the HL, LLC and HDC, LLC 15% escrow accounts to the purchaser for post

- closing expenses. As such, the Company reduced its

proportionate interest in the HL, LLC escrow by approximately $15,788 and its interest in the HDC, LLC escrow by $694,795 to reflect these payments and, during 2011, charged approximately

$710,583 to loss on sale of oil and gas properties on the statement of operations.

— OIL AND GAS PROPERTIES

Sale of La Cuerva and LLA 62 Blocks

During the first quarter of 2012, the Company sold all of its interest in Hupecol Cuerva, LLC ( “ HC, LLC ” ), which holds interests in the La Cuerva block and, pending approval of the

Colombian authorities, the LLA 62 block, together covering approximately 90,000 acres in the Llanos Basin in Colombia.

HC, LLC sold for $75 million, adjusted for working capital. 13.3% of the sales price of HC, LLC will be held in escrow to fund potential claims arising from the sale. Pursuant to its 1.6%

ownership interest in HC, LLC, the Company received 1.6% in the net sale proceeds after deduction of commissions, overriding royalty interest, and transaction expenses; subject to the escrow

holdback and a further contingency holdback by Hupecol of 1.3% of the sales price. Following completion of the sale of HC, LLC, the Company has no continuing interest in the La Cuerva and

LLA 62 blocks.

At December 31, 2011, the Company ’ s estimated proved reserves associated with the La Cuerva and LLA 62 blocks totaled 94,619 barrels of oil, which represented 82% of the Company ’ s

estimated proved oil and natural gas reserves. Sales of oil and gas properties under the full cost method of accounting are accounted for as adjustments of capitalized costs with no gain or loss

recognized, unless the adjustment significantly alters the relationship between capitalized costs and reserves. Since the sale of these oil and gas properties would significantly alter the

relationship, the Company recognized a gain on the sale of $315,119 during 2012, computed as follows:

The following table presents pro forma data that reflects revenue, income from continuing operations, net loss and loss per common share for 2012 and 2011 as if the HC, LLC sale had

occurred at the beginning of each period and excludes the gain on sale.

Impairments

During 2012, the Company completed operations on three test wells on the CPO 4 block in Colombia. Each of the test wells was determined to be noncommercial and was plugged and

abandoned. As a result of the determinations to plug and abandon each of those test wells, the Company included the costs related to those wells in the full cost pool for inclusion in the ceiling

test. The Company recorded an impairment charge of $46,235,574 during 2012 to write off costs not being amortized that were attributable to the drilling of the test wells on the CPO 4 block as

well as to write off seismic exploration and evaluation cost, general and administrative cost and environmental and governmental cost that were attributable to the test wells through December

- year life, an exercise price of $14.06 per share and were valued on the date of the grant using the

Black

- Scholes option

- pricing model with the following weighted average assumptions: risk

- free interest rate 2.095%, expected life of 5.685 years, (3) expected stock volatility 87.549%, and

expected future dividend yield of 0.142%. The Company determined the options qualify as ‘ plain vanilla ’ under the provisions of SAB 107 and the simplified method was used to estimate the

expected option life. Using this model yielded a value of $250,915 which was charged to expense in 2011. These options had a grant date fair value of $10.04 per share.

The 81,250 options granted under the annual director grants vest 20% on the grant date and 80% on March 13, 2012. These options had a ten

- 18Standby Letter of Credit

– CPO 4 Block

On November 5, 2009, JP Morgan Chase issued a Letter of Credit to Banco de Bogota S.A. for $2,037,500. Banco de Bogota then in turn issued a Stand by Letter of Credit to the Agency

De National Hydrocarbons to guaranty the Company ’ s compliance and proper execution of the work obligations relating to the phase one (1) work program of the CPO

- 4 block for the Company ’ s

25% interest in the Block. Per the Standby Letter of Credit issued between JP Morgan Chase and Banco de Bogota, the Company was required to keep on deposit with JP Morgan Chase

$2,037,500. In addition, the Company was required by JP Morgan Chase to pay fees associated with the Standby Letter of Credit equal to 1.0% per year of the amount, equal to $20,375.

On December 2, 2010, JP Morgan Chase amended the Letter of Credit to Banco de Bogota S.A. to increase the total amount of the Letter of Credit to $3,056,250. Banco de Bogota then in

turn issued an amended Stand by Letter of Credit to the Agency de National Hydrocarbons to guaranty the Company ’ s compliance and proper execution of the work obligations relating to the

phase one (1) work program for the CPO

- 4 block for the Company ’ s 37.5% interest in the Block. Per the amended Standby Letter of Credit issued between JP Morgan Chase and Banco de

Bogota, the date of expiration was extended until April 1, 2013 and the Company is required to keep on deposit with JP Morgan Chase $3,056,250. This increase in deposits was related to the

Company increasing its interest in the CPO 4 block from 25.0% to 37.5%. All other terms and conditions of the Letter of Credit remained unchanged. The Company paid JP Morgan fees

associated with the Standby Letter of Credit equal to 1.0% per year of the amount, equal to $32,070. The deposit with JP Morgan Chase is classified as Restricted cash

– letter of credit in the

accompanying balance sheets. Due to the settlement agreement with SK Innovation in which the Company assigned its 37.5% interest in the CPO

- 4 prospect, the Company will not be renewing

the Letter of Credit.

Legal Contingencies

The Company is subject to legal proceedings, claims and liabilities that arise in the ordinary course of its business. The Company accrues for losses associated with legal claims when

such losses are probable and can be reasonably estimated. These accruals are adjusted as further information develops or circumstances change.

At December 31, 2012, the Company was the subject of a formal investigation being conducted by the Securities and Exchange Commission (the “ SEC ” ). Pursuant to the investigation, the

Company received subpoenas issued by the SEC. The subpoenas called for the testimony of certain of the Company ’ s officers and the delivery of certain documents. The subpoenas were

issued pursuant to a nonpublic formal order of private investigation issued by the SEC on March 1, 2011, which followed a nonpublic informal inquiry commenced by the SEC in October 2010.

The Company received a copy of the nonpublic formal order of private investigation on February 10, 2012 in connection with a subpoena issued by the SEC. The SEC is investigating whether

there have been any violations of the federal securities laws and appears to have narrowed the focus of their investigation to matters relating to disclosures in the late 2009 and early 2010 time

period regarding resource potential for the CPO 4 prospect. The Company has presented information supporting its disclosure relative to resource potential on the CPO 4 prospect. The

investigation does not represent a conclusion by the staff that there have been any violations of the federal securities laws nor whether the staff would conclude that any enforcement action is

appropriate. At this time, the Company has not been made aware of a finding by the SEC of any securities violations. Also, as stated in the subpoenas issued by the SEC, the investigation does

not mean that the SEC has a negative opinion of any person, entity or security. The Company has cooperated fully, and is committed to continuing to cooperate fully, with the SEC in this matter.

It is not possible at this time to predict the timing or outcome of the SEC investigation, including whether or when any proceedings might be initiated, when these matters may be resolved or

what, if any, penalties or other remedies may be imposed, and whether any such penalties or remedies would have a material adverse effect on the Company ’ s consolidated financial position,

results of operations, or cash flows.

In connection with the ongoing investigation being conducted by the SEC and indemnification provisions contained in an engagement agreement with Global Hunter Securities, LLC

relating to our 2009 equity offering, in July 2012, the Company entered into an agreement with Global Hunter to settle any and all claims by Global Hunter related to reimbursement of attorney ’ s fees under the indemnity provision. During 2012, the Company paid a total of $490,850 to Global Hunter and in exchange for the payments, the Company was granted a full release by Global

Hunter Securities of any future claims or liabilities asserted by Global Hunter in connection with the offering. The payment to Global Hunter Securities was recorded as a charge to additional

paid in capital and is listed under the Cash Flow from Financing Activities in the statement of cash flows as Cost of capital. Filer: Houston American Energy Corp Form Type: 10

- 19On April 27, 2012, a purported class action lawsuit was filed in the U.S. District Court for the Southern District of Texas against the Company and certain of its executive officers: Steve

Silverman v. Houston American Energy Corp. et al ., Case No. 4:12

- CV

- 1332. The complaint generally alleges that, between March 29, 2010 and April 18, 2012, all of the defendants violated

Sections 10(b) of the Securities Exchange Act of 1934 and SEC Rule 10b

- 5 and the individual defendants violated Section 20(a) of the Exchange Act in making materially false and misleading

statements including certain statements related to the status and viability of the Tamandua #1 well. Two additional class action lawsuits were filed against the Company in May 2012. The

complaints seek unspecified damages, interest, attorneys ’ fees, and other costs. On September 20, 2012, the court consolidated the class action lawsuits and appointed a lead plaintiff and on

November 15, 2012 the lead plaintiffs filed an amended complaint. On January 14, 2013, we filed a motion to dismiss which remains pending before the court. The Company believes all of the

claims in the consolidated class action lawsuits are without merit and intends to vigorously defend against these claims. It is not possible at this time to predict the timing or outcome of the class

action lawsuits that have or may be filed. The Company expects to incur costs and to devote management time and resources to defending such lawsuits.

On July 19, 2012, a purported derivative cause of action was filed in the U.S. District Court for the Southern District of Texas against certain of the Company ’ s directors and officers and

the Company, as nominal defendant: E. Howard King, Jr., derivatively, on behalf of Houston American Energy Corp., v. John F. Terwilliger, John P. Boylan, Orrie Lee Tawes III, Stephen Hartzell,

James J. Jacobs, Kenneth A. Jeffers, defendants, and Houston American Energy Corp., as nominal defendant, Case No. 4:12

- CV

- 02182. The complaint asserts a cause of action by a shareholder

on behalf of the Company against certain of its directors and senior executive officers in connection with the June 11, 2012 approval of payment of certain bonuses, increases in salary, grant of

certain stock options and entry into certain Change in Control Agreements. The complaint alleges that the approval of such matters constituted breach of fiduciary duty and corporate waste and

seeks injunctive relief to bar each of the actions in question and seeks restitution. No damages have been or, by the nature of the derivative cause of action, are expected to be alleged against

the Company. The Company may, however, incur certain costs and demands on management time and resources in connection with the lawsuit. On February 26, 2013, an order was entered

granting a motion by the company to dismiss the lawsuit and providing leave to the plaintiff to amend its complaint to cure pleading deficiencies. The Plaintiff ’ s allotted time to amend its

complaint by the Court expired on March 26, 2013, and no amendment was made by the Plaintiff, effectively ending the lawsuit.

Environmental Contingencies

The Company ’ s oil and natural gas operations are subject to stringent federal, state and local laws and regulations relating to the release or disposal of materials into the environment or

otherwise relating to environmental protection. These laws and regulations may require the acquisition of a permit before drilling commences, restrict the types, quantities and concentration of

substances that can be released into the environment in connection with drilling and production activities, limit or prohibit drilling activities on certain lands lying within wilderness, wetlands

and other protected areas, and impose substantial liabilities for pollution resulting from our operations. Failure to comply with these laws and regulations may result in the assessment of

administrative, civil and criminal penalties, incurrence of investigatory or remedial obligations or the imposition of injunctive relief. Changes in environmental laws and regulations occur

frequently, and any changes that result in more stringent or costly waste handling, storage, transport, disposal or cleanup requirements could require the Company to make significant

expenditures to maintain compliance, and may otherwise have a material adverse effect on its results of operations, competitive position or financial condition as well as the industry in general.

Under these environmental laws and regulations, the Company could be held strictly liable for the removal or remediation of previously released materials or property contamination regardless of

whether the Company was responsible for the release or if its operations were standard in the industry at the time they were performed. The Company maintains insurance coverage, which it

believes is customary in the industry, although the Company is not fully insured against all environmental risks.

Development Commitments

During the ordinary course of oil and gas prospect development, the Company commits to a proportionate share for the cost of acquiring mineral interests, drilling exploratory or

development wells and acquiring seismic and geological information. Filer: Houston American Energy Corp Form Type: 10

- 22Reserve Information and Related Standardized Measure of Discounted Future Net Cash Flows

In December 2009, the Company adopted revised oil and gas reserve estimation and disclosure requirements. The primary impact of the new disclosures is to conform the definition of

proved reserves with the SEC Modernization of Oil and Gas Reporting rules, which were issued by the SEC at the end of 2008. The accounting standards update revised the definition of proved

oil and gas reserves to require that the average, first

- day

- of

- the

- month price during the 12

- month period before the end of the year rather than the year

- end price, must be used when estimating

whether reserve quantities are economical to produce. This same 12

- month average price is also used in calculating the aggregate amount of (and changes in) future cash inflows related to the

standardized measure of discounted future net cash flows. The rules also allow for the use of reliable technology to estimate proved oil and gas reserves if those technologies have been

demonstrated to result in reliable conclusions about reserve volumes. The unaudited supplemental information on oil and gas exploration and production activities has been presented in

accordance with the new reserve estimation and disclosure rules. Disclosures by geographic area include the United States and South America, which consists of our interests in Colombia. The

supplemental unaudited presentation of proved reserve quantities and related standardized measure of discounted future net cash flows provides estimates only and does not purport to reflect

realizable values or fair market values of the Company ’ s reserves. Volumes reported for proved reserves are based on reasonable estimates. These estimates are consistent with current

knowledge of the characteristics and production history of the reserves. The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries are more

imprecise than those of producing oil and gas properties. Accordingly, significant changes to these estimates can be expected as future information becomes available.

Proved reserves are those estimated reserves of crude oil (including condensate and natural gas liquids) and natural gas that geological and engineering data demonstrate with reasonable

certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved developed reserves are those expected to be recovered through

existing wells, equipment, and operating methods.

The reserve estimates set forth below were prepared by Lonquist & Co., LLC ( “ Lonquist ” ), utilizing reserve definitions and pricing requirements prescribed by the SEC. Lonquist is an

independent professional engineering firm specializing in the technical and financial evaluation of oil and gas assets. Lonquist ’ s report was conducted under the direction of Don E. Charbula,

P.E., Vice President of Lonquist. Mr. Charbula holds a BS in Petroleum Engineering from The University of Texas at Austin and is a registered professional engineer with more than 30 years of

experience in production engineering, reservoir engineering, acquisitions and divestments, field operations and management. Lonquist and its employees have no interest in the Company, and

were objective in determining the results of the Company ’ s reserves. Lonquist used a combination of production performance, offset analogies, seismic data and their interpretation, subsurface

geologic data and core data, along with estimated future operating and development costs as provided by the Company and based upon historical costs adjusted for known future changes in

operations or development plans, to estimate our reserves. The Company does not operate any of its oil and gas properties.

Total estimated proved developed and undeveloped reserves by product type and the changes therein are set forth below for the years indicated. Filer: Houston American Energy Corp Form Type: 10

- 23During 2012 and 2011, the Company recorded extensions and discoveries resulting principally from its ongoing drilling operations in Colombia. As of December 31, 2012, we had no proved

undeveloped ( “ PUD ” ) reserves. None of the PUD reserves as of December 31, 2011 were converted to proved developed producing reserves in 2012. All remaining PUD reserves as of December

31, 2011 were sold during 2012 in connection with the sale of our indirect 1.6% ownership in an entity holding interests in the La Cuerva and LLA 62 blocks in Colombia.

Negative revisions of 11,805 boe in PUD reserves during 2011 were due to the ongoing drilling program and subsequent changes in subsurface mapping. None of the PUD reserves as of

December 31, 2010 were converted to proved developed producing reserves in 2011.

The standardized measure of discounted future net cash flows relating to proved oil and gas reserves is computed using average first

- day

- of the

- month prices for oil and gas during the

preceding 12 month period (with consideration of price changes only to the extent provided by contractual arrangements), applied to the estimated future production of proved oil and gas

reserves, less estimated future expenditures (based on year

- end costs) to be incurred in developing and producing the proved reserves, less estimated related future income tax expenses (based

on year

- end statutory tax rates, with consideration of future tax rates already legislated), and assuming continuation of existing economic conditions. Future income tax expenses give effect to

permanent differences and tax credits but do not reflect the impact of continuing operations including property acquisitions and exploration. The estimated future cash flows are then discounted

using a rate of ten percent a year to reflect the estimated timing of the future cash flows. Filer: Houston American Energy Corp Form Type: 10

This report has been prepared to provide the management of Houston American Energy Corporation with a projection of estimated remaining Reserves and projected future net revenues as of

December 31, 2012. These estimates have not been adjusted for risk.

Standards of Practice

This report has been prepared in accordance with our understanding of the Securities and Exchange Commission, SX Reg. § 210.4

- 10, dated November 18, 1981 as amended September 19, 1989,

requiring adherence to definitions of “ Proved ” oil and gas Reserves. Additionally, at the request of Houston American, and within the most recently adopted and accepted SEC guidelines

( Modernization of Oil and Gas Reporting; Final Rule ; January 14, 2009), we have evaluated the Proved, Probable and Possible Reserves. The SEC oil and gas Reserve definitions are attached

hereto.

Liquid hydrocarbon volumes are expressed in standard 42

- gallon barrels. All natural gas volumes are sales gas expressed at the official pressure and temperature bases of the areas in which the

gas Reserves are located.

All currencies in this report are expressed in U.S. dollars.

Reserve Estimates

Extrapolation of historical production data was utilized for those producing properties where sufficient data were available to suggest decline trends. Reserves assigned to the remaining

producing properties and any non

- producing assets were determined by analogy to offset wells producing from similar formations or by volumetric analysis. Reserves assigned by analogy and

volumetric analysis are subject to greater revision than Reserves projected using established performance trends.

As of December 31, 2012, the PDP net remaining Reserves were estimated to be 2,100 barrels of oil/condensate, 150 barrels of natural gas liquids ( “ NGL ” ) and 33.93 MMcf of gas. The net present

value, discounted at 10%, of the PDP Reserves was $149,280. Of the total PDP revenue, 69% was derived from oil/condensate and natural gas liquids production. The Reserve life index ( “ R/P ” )

for the PDP Reserves was estimated to be 3.8 years based on a 6:1 conversion rate.

The PDNP behind

- pipe net remaining Reserves were estimated to be 4,070 barrels of oil/condensate and 50.45 MMcf of gas. The net present value, discounted at 10%, of the PDP Reserves was

$148,790. Of the total revenue, 71% was derived from oil/condensate production.

The total Proved net remaining Reserves were estimated to be 6,170 barrels of oil/condensate, 150 barrels of natural gas liquids and 84.38 MMcf of gas. The net present value, discounted at 10%,

of the total Reserves was $298,070. Of the total revenue, 70% was derived from oil, condensate, and natural gas liquids production. Filer: Houston American Energy Corp Form Type: 10

Page 3 of 5Operating Costs and Expenditures

Direct lease operating expenses were input as dollars per month into the economic models. These data were supplied by Houston American Energy Corporation. Where applicable, lease

operating costs were adjusted for non

- recurring costs. Operating costs were not escalated in this report. Severance and ad valorem taxes are deducted as a percentage of gross revenues or as a

charge per unit of production. The individual well projections of oil and gas cease when the operating expenses exceed the gross revenues.

Values Not Considered

In all cases, we have attempted to account for all deductions from gross revenues except for the following:

No value has been assigned to non

- producing acreage or to acreage held by production.

Report Qualifications

Estimates of future revenues were based on projections of recoverable hydrocarbons, rates of production, timing of recompletions and drilling, proration by state and federal agencies, operating

costs, direct taxes, and product prices. Any unusual combination of the many factors, including weather, political risk or acts of terrorism could result in future receipts being considerably less or

more than those estimated herein.

THE REVENUES AND PRESENT WORTH OF FUTURE NET REVENUES ARE NOT REPRESENTED TO BE MARKET VALUES EITHER FOR THE INDIVIDUAL PROPERTIES OR IN A

TOTAL PROPERTY BASIS.

The Reserves and revenues for specific properties should be considered in context with the overall report.

Data Sources

Historical production data were obtained from Houston American Energy Corporation and public sources, such as DrillingInfo.com, HPDI, LLC, Lasser Production Data Services, and IHS Energy

Data Services. This production data was generally updated though December 2012.

We retain in our files digital databases for all properties and certain other hard copy information that we believe pertinent. We have not inspected the properties evaluated in this report, nor have

we conducted independent well tests. Filer: Houston American Energy Corp Form Type: 10
