    Resale of 4,007,719 Shares of Common Stock, par value $0.001 Per Share


                             INFORMATION STATEMENT
                          TEXAS NEVADA OIL & GAS CO.


     This prospectus/information statement is being furnished to the
shareholders of Texas Nevada Oil & Gas Co., a Texas corporation, and the
stockholders of Houston American Energy Corp., a Delaware corporation, in
connection with the merger of TNOG with and into Houston American.

     On July 31, 2001, Houston American and TNOG entered into a Plan and
Agreement of Merger relating to the merger, which was amended and restated as of
September 26, 2001.  The completion of the merger was previously approved by a
number of TNOG's shareholders holding in excess of two-thirds of the outstanding
shares of TNOG common stock and by all of our current stockholders, subject to
completion, filing and effectiveness of the registration statement of which this
prospectus/information statement is a part.

     TNOG is a wholly-owned subsidiary of Unicorp, Inc., a Nevada corporation.
Unicorp will spin-off shares of TNOG's common stock to Unicorp's shareholders
prior to the merger of TNOG with and into Houston American. Since 1992, TNOG has
not undertaken any business operations.

     The merger of TNOG with and into Houston American will be completed 20 days
after the effectiveness of this registration statement and delivery of this
prospectus/information statement to TNOG's shareholders and our stockholders.
Immediately upon filing the required certificates related to the merger with the
Secretary of State of Texas and the Secretary of State of Delaware, we will
issue an aggregate of 596,469 shares of our common stock to TNOG's shareholders,
in exchange for their shares of TNOG common stock.  Our current stockholders
will retain their current shares of our common stock, an aggregate of 11,403,414
shares, and they will not be required to take any further action with respect to
the merger.

     This prospectus/information statement provides TNOG's shareholders with
detailed information about the merger, a description of which begins on page 18.
Each TNOG shareholder should give all of this information his careful attention,
as it describes his rights to either accept the consideration he is to receive
in the merger or to exercise his appraisal rights.  Each of TNOG's shareholders
should also carefully read the section entitled "Risk Factors" beginning on page
5 for a discussion of specific risks that he should consider in connection with
the merger.

     In addition to registering the resale of the 596,469 shares of our common
stock to be issued to TNOG's shareholders as a result of the merger, this
prospectus/information statement also relates to the aggregate resale of
4,007,719 shares of our common stock held by certain of our current
stockholders, all of which may be sold from time to time by the selling
stockholders.

     Neither the SEC nor any state securities regulator has approved the
securities to be issued under this prospectus/information statement or
determined if this prospectus/information statement is accurate or adequate.
Any representation to the contrary is a criminal offense.

       This prospectus/information statement is dated __________, 2001.


The information in this preliminary prospectus is not complete and may be
changed.  These securities may not be sold until the registration statement
filed with the Securities and Exchange Commission is effective.  This
preliminary prospectus is not an offer to sell nor does it seek an offer to buy
these securities in any state where the offer or sale is not permitted.

                    QUESTIONS AND ANSWERS ABOUT THE MERGER

Q.  What transaction is being proposed?

A.  We are proposing to acquire all of the outstanding shares of TNOG common
stock.  The acquisition will be effected by the merger of TNOG with and into
Houston American.

Q.  Why are the two companies proposing to merge?

A.  The merger provides TNOG's shareholders the opportunity to realize an
increase in the value of their original investment in Unicorp, Inc. due to
Houston American's ongoing oil and gas exploration and development activities.
Our stockholders will benefit from the merger because we will obtain TNOG's
relatively large shareholder base which could be useful in helping us develop a
public market for our common stock by providing the necessary float of publicly
held shares.  Due to the recent downturn in the economy, it has become
increasingly more difficult for companies without a public exit vehicle to raise
additional capital in private placements.  Therefore, developing a public market
for our common stock is expected to provide Houston American with greater access
to additional financing from public and private sources should it be necessary
for us to raise additional outside capital in the future.

Q.  What will I receive in the merger?

A.  TNOG's shareholders will be entitled to receive one share of Houston
American common stock in exchange for each share of TNOG common stock they own
at the time of the merger.  Our current stockholders will retain their current
shares of Houston American common stock and will not receive any additional
consideration as a result of the merger.  As of the date of this
prospectus/information statement, neither the TNOG common stock nor our common
stock is publicly traded.

Q.  As a TNOG shareholder, how will the merger affect me?

A.  After the merger, you will own shares of Houston American common stock and
you will have the same voting rights as our currently outstanding common stock.
We explained the merger's effect on the rights of our current stockholders to
each of them at the time they consented to the merger.



Q.  Why is there no TNOG shareholder meeting about this transaction?

A.  A TNOG shareholder meeting is not necessary because a number of TNOG
shareholders owning a sufficient number of shares of TNOG common stock to
approve the merger have already executed a written consent in favor of the
merger.

Q.  Why is there no meeting of our stockholders about this transaction?

A.  A meeting of our stockholders is not necessary because all of our current
stockholders have previously executed a written consent in favor of the merger.


Q.  Do TNOG's shareholders have dissenters' rights?

A.  Yes.  Under Texas law, TNOG's shareholders are entitled to dissenters'
rights.

Q.  When do you expect the merger to be completed?

A.  The merger will be completed 20 days after the date this
prospectus/information statement is first mailed to TNOG's shareholders and our
stockholders.  TNOG set July 1, 2001 and we set September 26, 2001 as the record
dates to determine TNOG's shareholders and our stockholders who are entitled to
be sent a copy of this prospectus/information statement.

                                       i
<PAGE>

Q.  Will the shares of Houston American common stock be listed on any stock
exchange?

A.  Following the merger, we will apply to list the shares of Houston American
common stock on the OTC Bulletin Board.

Q.  Will I be able to sell the shares that I receive in the merger?

A.  Only TNOG's shareholders and our stockholders whose shares of Houston
American common stock are being registered for resale pursuant to the
registration statement of which this prospectus/information statement is a part
will be able to resale their shares of Houston American common stock.  However,
if you are an affiliate of TNOG or Houston American, you will be subject to the
securities laws restrictions placed on the selling of shares by affiliates.

Q.  What are the tax consequences of the merger to me?

A.  The merger will be a taxable event to the TNOG shareholders.  The TNOG
shareholders will recognize gain or loss equal to the difference between (i) the
sum of the fair market value of the shares of our common stock they receive in
the merger and any cash they may have received in connection with the merger,
and (ii) their tax basis in their shares of TNOG common stock.  The merger will
not be a taxable event to the Houston American shareholders.  We urge you to
carefully read the complete explanation of the tax consequences of the merger on
pages 18 through 21.

Q.  What will my tax basis be in the shares I receive in the merger?

A.  The tax basis in shares of our common stock TNOG shareholders receive in the
merger will equal the fair market value of Houston American shares at the date
you own the shares.

Q.  Should TNOG's shareholders send in their stock certificates now?

A.  No.  After the merger is completed, we will appoint a transfer agent to
coordinate the exchange of TNOG's shareholders' current stock certificates
representing their shares of TNOG common stock.  The transfer agent will send
each TNOG shareholder a letter of transmittal and written instructions on how to
exchange their stock certificates.

Q.  Who can help answer my questions?

A.  If you would like additional copies of this prospectus/information
statement, or if you have questions about the merger, you should contact:

                                  THE MERGER

     TNOG will be merged with and into Houston American no sooner than 20 days
after the registration statement of which this prospectus/information statement
is a part has been declared effective and this prospectus/information statement
has been mailed to TNOG's shareholders and our stockholders.  The merger has
previously been approved by a number of TNOG's shareholders holding in excess of
two-thirds of the outstanding shares of TNOG common stock and by all of our
current stockholders.  Upon the effectiveness of the merger, TNOG's shareholders
will receive an aggregate of 596,469 shares of our common stock, or one share
for each share of TNOG common stock surrendered.  Our current stockholders will
retain their current shares of our common stock, an aggregate of 11,403,414
shares, and they will not be required to take any further action with respect to
the merger.  The terms and provisions of the agreement relating to the merger,
which is attached to this prospectus/information statement as Appendix A, are
                                                              ----------

     Under Texas law, TNOG's shareholders have the right to dissent from the

only receive the cash payment if they correctly dissent from the merger by
following specified procedures.  The relevant sections of the Texas Business
Corporation Act are attached to this prospectus/information statement as
Appendix B.

Reasons for the Merger

     TNOG's management believes that the merger will enable TNOG's shareholders
to realize an increase in the value of their original investment in Unicorp,
Inc. due to Houston American's ongoing oil and gas exploration and production
activities.  Over the last several years, there has been very little business
activity in Unicorp, Inc. and no business activity with respect to TNOG, despite
attempts to generate significant opportunities for both companies.  The
management of both Unicorp and TNOG concluded that the proposed merger with
Houston American provided the best prospect to establish value for their
shareholders.

     Our management believes that our stockholders will benefit from the merger
because Houston American will obtain TNOG's relatively large shareholder base
which could be useful in helping us develop a public market for our common stock
by providing the necessary float of publicly held shares.  Due to the recent
downturn in the economy, it has become increasingly more difficult for companies
without a public exit vehicle to raise additional capital in private placements.
Therefore, developing a public market for our common stock is expected to
provide Houston American with greater access to additional financing from public
and private sources should it be necessary to obtain additional outside capital
in the future.  The registration of shares for resale of certain of our existing
stockholders will also provide an exit strategy for them.  Without the merger
with TNOG and the acquisition of its shareholder base, there would be no
meaningful market for the resale of our stock.

Governmental Approvals

     We are not aware of any governmental approvals required to complete the
merger other than compliance with the applicable corporate and securities laws
of the States of Texas and Delaware.

Certain Tax Consequences (See page 20)

     It is expected that, for United States federal income tax purposes, the
merger will not qualify as a tax-free reorganization.  Accordingly, the merger
will be a taxable transaction for the TNOG shareholders.  Our current
stockholders will not recognize gain or loss as a result of the merger.


     The actual tax consequences of the merger to you will depend on your
specific situation.  We strongly urge you to consult your own tax adviser for a
full understanding of the merger's tax consequences.

Risk Factors (See page 5)

     An investment in our common stock involves significant risks and should not
be made without reference to the risk factors incorporated into this
prospectus/information statement.

Registration of Shares

     This prospectus/information statement relates to the aggregate resale of
596,469 shares of our common stock which are to be issued to TNOG's shareholders
as a result of the merger, as well as the aggregate resale of 4,007,719 shares
of our common stock held by certain of our current shareholders, all of which
may be sold from time to time by the selling stockholders. We will not receive
any proceeds from the resale of any of the common stock by the selling
stockholders.

Forward-Looking Statements

     There are forward-looking statements in this prospectus/information
statement and in other documents to which you are referred that are subject to
risks and uncertainties.  These forward-looking statements include information
about our possible or assumed future results of operations or our performance
after the merger is completed.  When any of the words "believes," "expects,"
"anticipates," "intends," "estimates" or similar expressions are used, forward-
looking statements are being made.  Many possible events or factors could affect
the actual financial results and performance of each of the companies before the
merger and of the combined company after the merger, and these events or factors
could cause those results or performance to differ significantly from those
expressed in these forward-looking statements.  Many of these risks and
uncertainties are not within our

                       COMPARATIVE PER SHARE INFORMATION

     The table below contains historical and pro forma per share information
about the net loss and book value of Houston American. and TNOG. The per share
information has been derived from the audited, unaudited and unaudited pro forma
financial statements referred to above in "Selected Historical and Unaudited Pro
Forma Financial Information" for Houston American and in "Selection Historical
Financial Information" for TNOG. You should read the information below together
with "Houston American Energy Corp. Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Texas Nevada Oil & Gas Co.
Management's Discussion and Analysis of Financial Condition and Results of
Operations."


     The unaudited pro forma combined per share information does not necessarily
indicate the operating results that would have been achieved had the merger of
Houston American and TNOG actually occurred at the beginning of the periods
presented nor does it indicate future results of operations of financial
condition.

             MARKET VALUE OF SECURITIES AND FUTURE DIVIDENDS POLICY

     As of the date of this prospectus/information statement, neither the TNOG
common stock nor our common stock is publicly traded, although the TNOG common
stock has been registered under the Securities Exchange Act of 1934. We
anticipate applying to list our common stock on the OTC Bulletin Board prior to
the effectiveness of the merger. Following UniCorp's spin-off of the TNOG shares
to UniCorp's shareholders, there will be approximately 992 shareholders of
record of TNOG common stock. As of September 28, 2001, there were 30
stockholders of record of our common stock.

     We presently anticipate that all of our future earnings will be retained
for the development of our business.  Therefore, we do not expect to pay any
cash dividends in the foreseeable future.  The payment of any future dividends
will be at the discretion of our board of directors and will be based on our
future earnings, financial condition, capital requirements and other relevant
factors.

                                  RISK FACTORS

     An investment in our common stock involves certain risks.  Prospective
investors should carefully review the following factors, together with the other
information contained in this prospectus/information statement, prior to making
a decision to invest in our common stock.  The future trading price of shares of
our common stock will be affected by the performance of our business relative
to, among other things, competition, market conditions and general economic and
industry conditions.


RISKS RELATING TO AN INVESTMENT IN HOUSTON AMERICAN

Revenue from our oil and gas properties often depends on factors beyond our
control

     The profitability of our oil and gas operations depends upon factors which
are beyond our control, including:

     .  Natural gas and crude oil prices, which are subject to substantial
        fluctuations as a result of variations in supply and demand and
        seasonality;

     .  Future market, economic and regulatory factors which may materially
        affect our sales of gas production; and

     .  Business practices of our competitors in the oil and gas operating
        sector.

We may be unable to meet our capital requirements which may slow down or curtail
our business plans

     Since our inception on April 2, 2001 to June 30, 2001, we have suffered
operational losses totaling $19,517 and we expect to continue to have
substantial capital expenditure and working capital needs. If low natural gas
and oil prices, operating difficulties or other factors, many of which are
beyond our control, cause our revenues or cash flows from operations to
decrease, we may be limited in our ability to obtain the capital necessary to
complete our development, exploitation and exploration programs. We have not
thoroughly investigated whether this capital would be available, who would
provide it, and on what terms. If we are unable, on acceptable terms, to raise
the required capital, our business may be seriously harmed or even
terminated.

The estimates of any proved reserves on our leaseholds are currently unknown

     As of the date of this prospectus/information statement, we have not
obtained estimates of the proved natural gas and oil reserves on our leaseholds,
if any.  Determining the estimates of proved reserves is a complex process that
requires significant decisions and assumptions in the evaluation of available
geological, geophysical, engineering and economic data for each reservoir.  We
anticipate obtaining a determination of the estimates of our proved reserves, if
any, prior to the end of 2001.  The actual survey of our leaseholds may
determine that our properties do not have proved natural gas and oil reserves,
which could have a material adverse effect on our business, financial condition,
results of operations and ability to continue our operations.

We are not the operator of our oil and gas properties

     Under the terms of the Operating Agreements related to our oil and gas
properties, Moose Operating Co., Inc., a Texas corporation affiliated with John
F. Terwilliger, our sole director and executive officer, is the operator of our
oil and gas wells and controls the drilling activities to be conducted on our
properties.  Therefore, we have limited control over certain decisions related
to activities on our properties, which could effect our results of operations.
Decisions over which we have limited control include:

     .  the timing and amount of capital expenditures;

     .  the timing of initiating the drilling and recompleting of wells;

     .  the extent of operating costs; and

     .  the level of ongoing production.


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 stockholders

     Upon the effectiveness of the merger, John F. Terwilliger, our sole
director and executive officer, will beneficially own approximately 61.6 percent
of our outstanding common stock. As a result, he will continue to be in a
position to significantly influence or control the outcome of matters requiring
a stockholder vote, including the election of directors, the adoption

                                       7
<PAGE>

of any amendment to our certificate of incorporation or bylaws, and the approval
of mergers and other significant corporate transactions. His control of Houston
American may delay or prevent a change of control on terms favorable to the
other stockholders and may adversely affect the voting and other rights of other
stockholders.

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 retain John F. Terwilliger, our
sole director and executive officer, and to attract other experienced management
and non-management employees, including engineers, geoscientists and other
technical and professional staff. 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.

Our certificate of incorporation and bylaws and the Delaware General Corporation
Law contain provisions that could discourage an acquisition or change of control
of Houston American

     Our certificate of incorporation authorizes our board of directors to issue
preferred stock and common stock without stockholder approval. If our board of
directors elects to issue preferred stock, it could be more difficult for a
third party to acquire control of us. In addition, provisions of our certificate
of incorporation and bylaws could also make it more difficult for a third party
to acquire control of us. These provisions include a denial of cumulative voting
rights, limitations on stockholder proposals at meetings of stockholders, and
restrictions on the ability of our stockholders to call special meetings. Our
certificate of incorporation provides that our board of directors is divided
into three classes, each elected for staggered three-year terms. Although we
currently have only one director, we anticipate additional directors will be
added to our board of directors shortly after the completion of the merger.
Thus, control of our board of directors cannot be changed in one year; rather,
at least two annual meetings must be held before a majority of the members of
our board of directors could be changed. In addition, the Delaware General
Corporation Law imposes restrictions on mergers and other business combinations
between us and any holder of 15 percent or more of our outstanding common stock.

     These provisions of Delaware law and our certificate of incorporation and
bylaws may delay, defer or prevent a tender offer or takeover attempt that a
stockholder might consider in his best interest, including attempts that might
result in a premium over the market price for the common stock.

TNOG shareholders may succeed to a portion of the TNOG tax liability

     The merger will be a taxable transaction for federal income tax purposes.
It is likely that the Internal Revenue Service will consider the merger a
taxable sale by TNOG of its assets and the subsequent liquidation of TNOG.  If
we do not pay the tax liability created by this deemed sale of assets, there is
a risk that the Internal Revenue Service would assert that the TNOG shareholders
are distributees of property of TNOG and that each TNOG shareholder is liable
for the unpaid taxes to the extent of the value of property it received in the
deemed liquidation.

TNOG's shareholders are entitled to dissenter's rights

     TNOG's shareholders who do not consent to the merger may, under certain
circumstances and by following procedures prescribed by the Texas Business
Corporation Act exercise dissenter's rights and receive cash for the fair value
of their shares. Dissenters must follow the appropriate procedures under Texas
law or suffer the termination or waiver of such rights. In the event a TNOG
shareholder relinquishes or loses his dissenter rights, he will receive the same
number of shares of our common stock that he would have received in the merger
had such dissenter not attempted to exercise his dissenter's rights.

Need for additional financing

     We are a development stage company and our revenue is currently
insufficient to cover our ongoing exploration and development expenses and our
general operating costs. Therefore, our ability to continue as a going concern.
Our ability to continue our operations is dependent on the willingness and
ability of Moose Oil & Gas Company and Moose Operating Co., Inc.


                                       8
<PAGE>

(entities affiliated with John F. Terwilliger, our sole director and executive
officer) to continue funding our operations and our ability to obtain additional
sources of financing as discussed below in "Houston American Energy Corp.
Management's Discussion and Analysis of Financial Condition and Results of
Operations - Liquidity and Capital Resources." As of the date of this
prospectus/information statement, our relationships with Moose Oil & Gas Company
and Moose Operating Co., Inc. are stable and we have no reason to doubt the
willingness of those two entities to continue providing additional funding.
However, if Moose Oil & Gas Company and Moose Operating Co., Inc. discontinue
funding our operations and we are unable to obtain alternative financing when
needed on acceptable terms, if at all, we may be unable to continue our
operations.

Shares of our common stock may be "penny stocks"

     If the market price per share of our common stock is less than $5.00, the
shares of our common stock will be "penny stocks" as defined in the Exchange
Act. As a result, an investor may find it more difficult to dispose of or obtain
accurate quotations as to the price of the shares of our common stock being
registered under this prospectus/information statement. In addition, the "penny
stock" rules adopted by the SEC under the Exchange Act subject the sale of
shares of our common stock to regulations which impose sales practice
requirements on broker-dealers. For example, broker-dealers selling penny stocks
must, prior to effecting the transaction, provide their customers with a
document which discloses the risks of investing in penny stocks.

     Furthermore, if the person purchasing the securities is someone other than
an accredited investor or an established customer of the broker-dealer, the
broker-dealer must also approve the potential customer's account by obtaining
information concerning the customer's financial situation, investment experience
and investment objectives. The broker-dealer must also make a determination
whether the transaction is suitable for the customer and whether the customer
has sufficient knowledge and experience in financial matters to be reasonably
expected to be capable of evaluating the risk of transactions in penny stocks.
Accordingly, the SEC's rules may limit the number of potential purchasers of
shares of our common stock. Moreover, various state securities laws impose
restrictions on transferring "penny stocks," and, as a result, investors in our
common stock may have their ability to sell their shares impaired.


RISKS RELATED TO THE NATURAL GAS AND OIL INDUSTRY

Our operations may expose us to environmental liabilities

     Any leakage of crude oil and saltwater from the subsurface portions of our
wells could cause degradation of fresh groundwater resources, as well as surface
damage, potentially resulting in suspension of operation of the wells, fines and
penalties from governmental agencies, expenditures for remediation of the
affected resource, and liabilities to third parties for property damages and
personal injuries.

Oil and natural gas prices are volatile, which could have a material adverse
effect on our business

     Natural gas and oil prices are subject to wide fluctuations in response to
relatively minor changes in or perceptions regarding supply and demand.
Historically, the markets for natural gas and oil have been volatile, and they
are likely to continue to be volatile in the future.  It is impossible to
predict oil and natural gas price movements with certainty.  Lower natural gas
and oil prices may not only decrease our revenues on a per unit basis but also
may reduce the amount of natural gas and oil that we can produce economically.
A substantial or extended decline in natural gas and oil prices may have a
material adverse affect on our future business, financial condition, results of
operations, liquidity and ability to finance planned capital expenditures.

Drilling wells is speculative, often involving significant costs

     Developing and exploring for natural gas and oil reserves involves a high
degree of operational and financial risk.  The budgeted costs of drilling,
completing and operating wells are often exceeded and can increase significantly
when drilling costs rise due to a tightening in the supply of various types of
oilfield equipment and related services.  If our actual drilling and development
costs are significantly more than our estimated costs, our business could be
negatively affected.



                                       9
<PAGE>

The natural gas and oil business involves many uncertainties and operating risks
which can prevent us from realizing profits and cause substantial losses

     Development, exploitation and exploration activities may be unsuccessful
for many reasons, including title problems, weather, cost overruns, and
mechanical difficulties.  Moreover, the successful drilling of a natural gas or
oil well does not ensure a profit on investment.  Exploratory wells bear a much
greater risk of loss than development wells.  A variety of factors, both
geological and market-related, can cause a well to become uneconomical or only
marginally economic.  If we experience any of these problems, it could have a
material adverse effect on our results of operations and we could suffer
substantial losses.

Competition in our industry is intense and we may not be able to compete
effectively

     Competition for the acquisition of natural gas and oil properties and the
equipment and labor required to operate and to develop properties is very
intense in the oil and gas industry.  We compete with many major and independent
companies, many of which have greater financial and other resources than Houston
American.  Therefore, our future results of operations will depend on our
ability to conduct operations, to evaluate and select suitable properties and to
consummate transactions in this highly competitive environment.

We are subject to complex laws and regulations, including environmental
regulations, which can adversely affect the cost, manner or feasibility of doing
business

     The natural gas and oil industry is subject to extensive laws and
regulations, including environmental laws and regulations.  Compliance with
environmental and other governmental regulations often requires large
expenditures.  Additionally, failure to comply with these laws and regulations,
which are subject to change over time, may subject us to administrative, civil
and criminal penalties and, in some instances, could result in the suspension or
termination of our operations.  Accordingly, the costs of complying with these
laws and regulations and any penalties, suspensions, terminations or regulatory
changes could have a material adverse effect on our business, financial
condition and results of operations.


                  HOUSTON AMERICAN ENERGY CORP. MANAGEMENT'S
                          DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATION


     The following discussion contains certain forward-looking statements that
are subject to business and economic risks and uncertainties, and actual results
could differ materially from those forward-looking statements. The following
discussion regarding our financial condition and results of operations should be
read in conjunction with the financial statements and related notes.

General

     Houston American Energy Corp. is an oil and gas exploration and production
company. Currently, Houston American's business activities are conducted in the
State of Texas.

Results of Operations

     Since our inception on April 2, 2001 to June 30, 2001, we have incurred an
operating loss of $19,517. Our revenues during that period were approximately
$2,900 and our total exploration and development costs associated with the three
wells we have drilled were $199,733.

Liquidity and Capital Resources

     Our management anticipates that our current financing in place will meet
our anticipated objectives and business operations for approximately the next 24
months.  For that period, we anticipate that our committed share of the costs
associated with completing, testing and connecting our third well, Sartwell
No. 5, will be approximately $875,000.  Additionally, we anticipate drilling
expenses and costs of approximately $1,250,000 related to our



                                       10
<PAGE>

interest in two deep wells which will be drilled in the next six to eight
months, and an additional $1,250,000 for two other wells we anticipate drilling
prior to the end of the year 2002.

     As discussed by our accountants in the audited financial statements
attached to this prospectus/information statement, our revenue is currently
insufficient to cover our costs and expenses. In addition to the income we are
receiving from our wells, Moose Oil & Gas Company and Moose Operating Co., Inc.
are currently loaning us the funds needed to continue our operations. John F.
Terwilliger, our sole director and executive officer, is also the sole director,
chief executive officer and majority shareholder of Moose Oil & Gas Company,
which is the parent of Moose Operating Co., Inc. All funds advanced to us by
Moose Oil & Gas Company and Moose Operating Co., Inc. bear interest at 10
percent per annum and are payable on demand.

     To the extent our revenue shortfall exceeds the willingness and ability of
Moose Oil & Gas Company and Moose Operating Co., Inc. to continue loaning us the
funds needed for our operations, we anticipate raising any additional capital
needed from outside investors coupled with bank or mezzanine lenders. As of the
date of this prospectus/information statement, we have not entered into any
negotiations with any third parties to provide such capital. If Moose Oil & Gas
Company and Moose Operating Co., Inc. discontinue funding our operations and we
are unable to obtain additional capital from third parties, it could have a
material adverse effect on our business, financial condition and results of
operations and could cause us to discontinue our operations.

                   BUSINESS OF HOUSTON AMERICAN ENERGY CORP.

Current Strategy

     Our primary focus over the next 12 months is the exploration and production
of two significant leasehold interests we own in Lavaca County, Texas.  In
addition to seeking out oil and gas property prospects using advanced seismic
techniques, we will utilize our management's contacts to identify potential
acquisition targets.  In searching for potential acquisition targets, we will
focus primarily in the Onshore Texas Gulf Coast Region of the State of Texas,
where our management has been involved in oil and gas exploration and production
activities since 1983.

     In addition to our own drilling activities and acquisition strategy, we may
encourage others in the oil and gas industry to enter into partnerships or joint
ventures with us for purposes of acquiring properties and conducting drilling
and exploration activities.

Exploration and Development Activities

     Our exploration and development activities focus on the identification and
drilling of new productive wells and the acquisition of existing producing wells
from other producers.

Drilling Activities

     As of the date of this prospectus/information statement, we have drilled
and completed two gross wells (0.45 net wells), including connecting the wells
to the pipeline system, and we have drilled and are completing the last of our
three test wells we are committed to drill on three of our four leaseholds in
Lavaca County, Texas. Based on log analysis comparing the first two wells to
other producing wells in the immediate area, we believe them to be capable of
profitable production. Currently, those wells are producing a non-material
amount of natural gas. As of the date of this prospectus/information statement,
we have not flow tested any of the wells.

     The log analysis conducted during the drilling of the third well causes us
to believe that the third well is also capable of profitable production. As of
the date of this prospectus/information statement, production casing has been
run on the third well and it is awaiting a completion rig in order to attempt to
complete the well. If the third well is successful, it will be immediately
connected to the pipeline system.

     Our goal in drilling our first two wells was to test the Frio and Miocene
Formations at different depths above 3,500 feet. The third well was drilled in
order to test the Lower Wilcox Formation at depths down to 16,500 feet.



                                       11
<PAGE>

     The following table summarizes our development drilling activity for the
period from our inception on April 2, 2001 through August 31, 2001. There is no
correlation between the number of productive wells completed during any period
and the aggregate reserves attributable to those wells. All of the wells we have
drilled are natural gas wells.

      Total                Productive                Dry
      -----                ----------                ---

   Drilled     Net    Drilled      Net     Drilled         Net

      3       1.00       2        0.45        0             0

     A "gross well" is a well in which we own a working interest. A "net well"
is deemed to exist when the sum of the fractional working interests in gross
wells equals one. The total of 1.00 net wells included in the foregoing chart
includes our third well (0.55 net wells). Our original interest in that well
(0.15 net wells) increased as a result of the election by several working
interest owners to be treated as non-consenting parties on the well. Pursuant to
the terms of the operating agreement related to the well, which is between Louis
Dreyfus, Seisgen Exploration, Inc. and Moose Oil & Gas Company and is attached
as an exhibit to the registration statement of which this prospectus/information
statement is a part, we will continue to own our respective share of each non-
consenting party's interest in the well (an additional 0.40 net wells) until the
total proceeds from the sale of gas produced from the well attributable to each
non-consenting party's interest in the well is equal to the total of:

     .  100 percent of the costs of operating the well attributable to the
        applicable non-consenting party's original interest in the well;
        and

     .  400 percent of the costs and expenses of drilling, testing and
        completing the well attributable to the applicable non-consenting
        party's original interest in the well.

Marketing

     We anticipate marketing substantially all of the oil and gas to be produced
from our properties to Kinder Morgan Pipeline, Inc., Pinnacle Natural Gas Co.
and Texas Gas Plants, L.P. As of the date of this prospectus, we have entered
into gas purchase agreements with Kinder Morgan and Pinnacle (as successor to
Dominion Pipeline Company) with respect to the Kalmus No. 1 well and the Carl
Klimitchek No. 2 well, respectively. Each of those agreements, which are
attached as exhibits to the registration statement of which this
prospectus/information statement is a part, were entered into by Moose Operating
Co., Inc. and we were assigned the rights to the agreements in connection with
the purchase of our oil and gas interests from Moose Oil & Gas Company. Each
agreement requires us to sell all of the gas we produce from the applicable well
to the purchaser at fluctuating prices, which are based on the appropriate index
and, in the case of the agreement with Pinnacle, the average gas liquids content
of the gas we deliver.

     Although we have not entered into an agreement with Texas Gas Plants, L.P.
as of the date of this prospectus/information statement, we have held
preliminary discussions with representatives of Texas Gas Plants regarding
entering into a gas purchase agreement related to the Sartwelle No. 5 well.  Due
to the proximity of an available connection to Texas Gas Plants' pipeline to the
location of the Sartwelle No. 5 well (less than a mile) and the prior
contractual relationships between Moose Operating Co. and Shell Western E&P,
Inc., an affiliate of Texas Gas Plants, we believe that entering into a gas
purchase agreement with Texas Gas Plants will represent our best opportunity for
marketing the gas we produce from the Sartwelle No. 5 well.  Although we cannot
be certain that our initial discussions will result in an actual agreement, the
representatives of Texas Gas Plants have expressed an interest in entering into
a gas purchase agreement if the testing of the Sartwelle No. 5 well establishes
that it appears capable of profitable production.

Production

     As of the date of this prospectus/information statement, we have not had
any material production of oil or natural gas from our wells. Each of our first
two wells began producing natural gas in the first week of July 2001. Through
August 31, 2001, we have received total gross revenues of $7,671.44, excluding
production taxes, from the sale of the natural gas produced from the wells.



                                       12
<PAGE>

Reserves

     Inasmuch as we have only recently completed the drilling of our first two
test wells, the proved reserves on our leaseholds, if any, have not been
established as of the date of this prospectus/information statement. We
anticipate that a proved reserve determination will be made for each of our
wells by the end of 2001. However, if our third well, Sartwell No. 5, is
completed and begins producing prior to that time, we will immediately contract
for a proved reserve study.

Leaseholds


     As of the date of this prospectus/information statement, we have leasehold
interests in four oil and gas properties in Lavaca County, Texas, which
represent a total of 943.8 gross and 157.55 net developed acres and 1,195 gross
and 149.38 net undeveloped acres. A "gross acre" is an acre in which a working
interest is owned. The number of gross acres represents the sum of acres in
which a working interest is owned. A "net acre" is deemed to exist when the sum
of the fractional working interests in gross acres equals one. The number of net
acres is the sum of the fractional working interests in gross acres expressed in
whole numbers or fractions.

     Operational Hazards and Insurance.  Our development, exploitation and
exploration activities may be unsuccessful for many reasons, including weather,
cost overruns, equipment shortages and mechanical difficulties.  Moreover, the
successful drilling of a natural gas and oil well does not ensure a profit on
investment.  A variety of factors, both geological and market-related, can cause
a well to become uneconomical or only marginally profitable.

     Our business involves a variety of operating risks which may adversely
affect our profitability, including:

     .  fires;

     .  explosions;

     .  blow-outs and surface cratering;

     .  uncontrollable flows of oil, natural gas, and formation water;

     .  natural disasters, such as hurricanes and other adverse weather
        conditions;

     .  pipe, cement, or pipeline failures;

     .  casing collapses;

     .  embedded oil field drilling and service tools;

     .  abnormally pressured formations; and

     .  environmental hazards, such as natural gas leaks, oil spills, pipeline
        ruptures and discharges of toxic gases.

     If we experience any of these problems, it could affect well bores,
gathering systems and processing facilities, which could adversely impact our
ability to conduct operations.  We could also incur substantial losses as a
result of:

     .  injury or loss of life;

     .  severe damage to and destruction of property, natural resources and
        equipment;

     .  pollution and other environmental damage;



                                       13
<PAGE>

     .  clean-up responsibilities;

     .  regulatory investigation and penalties;

     .  suspension of our operations; and

     .  repairs to resume operations.

     In accordance with industry practice, our insurance protects us against
some, but not all, operational risks and we do not carry business interruption
insurance at levels that would provide enough funds for us to continue operating
without access to additional funds. For some risks, we may not obtain insurance
if we believe the cost of available insurance is excessive relative to the risks
presented. In addition, pollution and environmental risks generally are not
fully insurable. Therefore, our insurance may be inadequate to cover any losses
or exposure for liability. If a significant accident or other event occurs and
is not fully covered by insurance, it could adversely affect our operations and
financial condition.

     Reserves. Our business strategy requires us to develop reserves through
acquisitions of proved natural gas and oil properties, further development of
our existing properties, and exploration activities. Properties may not be
available for acquisition in the future on terms we find attractive. A
substantial decrease in the availability of proved natural gas and oil
properties in our areas of operation, or a substantial increase in their cost,
would adversely affect our ability to develop and continuously replace our
reserves as they are depleted. In addition, our exploration and development
activities may not be successful. If we fail to develop and continuously replace
our reserves, our level of production and cash flows will be adversely affected.

     We have undeveloped properties that will require substantial costs to
develop. We expect to continue incurring costs to acquire, explore and develop
oil and gas properties, and our management predicts that these costs, together
with general and administrative expenses, will be in excess of funds available
from revenues from properties owned by us. It is anticipated that the source of
funds to carry out exploration and development will come from a combination of
our production revenues, sales of our securities, and funds from other funding
transactions in which we might engage.

     We will periodically review the carrying value of our natural gas and oil
properties under the full cost accounting rules of the SEC. Under these rules,
capitalized costs of proved natural gas and oil properties may not exceed the
present value of estimated future net revenues from proved reserves, discounted
at an annual rate of 10 percent. Application of this "ceiling" test requires
pricing future revenue at the unescalated prices in effect as of the end of each
fiscal quarter and requires a write-down for accounting purposes if the ceiling
is exceeded, even if prices were depressed for only a short period of time. In
the future, we may be required to write down the carrying value of our natural
gas and oil properties when natural gas and oil prices are depressed or
unusually volatile, which would result in a charge against our earnings. Once
incurred, a write-down of the carrying value of our natural gas and oil
properties is not reversible at a later date.

Financing of Drilling Activities

     Shortages or an increase in costs of drilling rigs, equipment, supplies or
personnel could delay or adversely affect our operations, which could have a
material adverse effect on our business, financial condition and results of
operations.  Recently, drilling activity in many geographic areas has increased,
resulting in increases in associated costs, including those related to drilling
rigs, equipment, supplies and personnel and the services and products of other
vendors to the industry.  We do not have any contracts with providers of
drilling rigs and we may find that drilling rigs will not be readily available
when we need them.

Volatility of Oil and Gas Prices

     As an independent oil and gas producer, our revenue, profitability and
future rate of growth are substantially dependent upon the prevailing prices of,
and demand for, natural gas, oil, and condensate.  Our realized profits affect
the amount of cash flow available for capital expenditures.  Our ability to
maintain or increase our borrowing capacity and to obtain additional capital on
attractive terms is also substantially dependent upon oil and



                                       14
<PAGE>

gas prices. From time to time, oil and gas prices have been depressed. However,
prices for oil and gas have recently increased materially, only to fall back to
their current levels. It is impossible to predict future oil and natural gas
price movements with any certainty. Any continued and extended decline in the
price of oil or gas could have a material adverse effect on our financial
position, cash flows and results of operations and may reduce the amount of our
oil and natural gas that can be produced economically.

     Prices for oil and natural gas are subject to wide fluctuation in response
to relatively minor changes in the supply of, and demand for, oil and gas,
market uncertainty and a variety of additional factors that are beyond our
control. Among the factors that can cause the volatility of oil and gas prices
are:

     .  worldwide or regional demand for energy, which is affected by economic
        conditions;

     .  the domestic and foreign supply of natural gas and oil;

     .  weather conditions;

     .  domestic and foreign governmental regulations;

     .  political conditions in natural gas and oil producing regions;

     .  the ability of members of the Organization of Petroleum Exporting
        Countries to agree upon and maintain oil prices and production levels;
        and

     .  the price and availability of other fuels.

Competition

     Competition in the oil and gas industry is intense and we compete with
major and other independent oil and gas companies with respect to the
acquisition of producing properties and proved undeveloped acreage. Our
competitors actively bid for desirable oil and gas properties, as well as for
the equipment and labor required to operate and develop the properties. Many of
our competitors, however, have financial resources and exploration and
development budgets that are substantially greater than ours and may be able to
absorb the burden of any changes in federal, state and local laws and
regulations more easily than we can, which would adversely affect our
competitive position. These competitors may be able to pay more for natural gas
and oil properties and may be able to define, evaluate, bid for and purchase a
greater number of properties than we can. Our ability to acquire additional
properties and develop new and existing properties in the future will depend on
our capability to conduct operations, to evaluate and select suitable properties
and to consummate transactions in this highly competitive environment.

Regulation

     Our business and the oil and gas industry in general are subject to
extensive laws and regulations, including environmental laws and regulations. We
may be required to make large expenditures to comply with environmental and
other governmental regulations. State and federal regulations, including those
enforced by the Texas Railroad Commission as the primary regulator of the oil
and gas industry in the State of Texas, are generally intended to prevent waste
of oil and gas, protect rights to produce oil and gas between owners in a common
reservoir and control contamination of the environment. Matters subject to
regulation in the State of Texas include:

     .  location and density of wells;

     .  the handling of drilling fluids and obtaining discharge permits for
        drilling operations;

     .  accounting for and payment of royalties on production from state,
        federal and Indian lands;

     .  bonds for ownership, development and production of natural gas and oil
        properties;



                                       15
<PAGE>

     .  transportation of natural gas and oil by pipelines;

     .  operation of wells and reports concerning operations; and

     .  taxation.

     Under these laws and regulations, we could be liable for personal injuries,
property damage, oil spills, discharge of hazardous materials, remediation and
clean-up costs and other environmental damages. Failure to comply with these
laws and regulations also may result in the suspension or termination of our
operations and subject us to administrative, civil and criminal penalties.
Moreover, these laws and regulations could change in ways that substantially
increase our costs. Accordingly, any of these liabilities, penalties,
suspensions, terminations or regulatory changes could materially adversely
affect our financial condition and results of operations.

     The availability of a ready market for oil and gas production depends on
several factors beyond our control. These factors include regulation of oil and
gas production, federal and state regulations governing environmental quality
and pollution control, the amount of oil and gas available for sale, the
availability of adequate pipeline and other transportation and processing
facilities and the marketing of competitive fuels.

     Pipelines are subject to the jurisdiction of various federal, state and
local agencies. We take all necessary steps to comply with applicable
regulations and we believe that we are in substantial compliance with applicable
statutes, rules, regulations and governmental orders although we cannot be
certain that this is or will remain the case. The following discussion of the
regulation of the United States natural gas industry is not intended to
constitute a complete discussion of the various statutes, rules, regulations and
environmental orders to which our operations may be subject.

     Regulation of Natural Gas Exploration and Production. Our natural gas
operations are subject to various types of regulation at the federal, state and
local levels. Prior to commencing drilling activities for a well, we are
required to procure permits and/or approvals for the various stages of the
drilling process from the applicable state and local agencies in the state in
which the area to be drilled is located. Permits and approvals include those for
the drilling of wells, and regulations include maintaining bonding requirements
in order to drill or operate wells and the location of wells, the method of
drilling and casing wells, the surface use and restoration of properties on
which wells are drilled, the plugging and abandoning of wells, and the disposal
of fluids used in connection with operations.

     Our operations are also subject to various conservation laws and
regulations. These include the regulation of the size of drilling and spacing
units or portion units and the density of wells, which may be drilled and the
unitization or pooling of natural gas properties. In this regard, some states
allow the forced pooling or integration of tracts to facilitate exploration
while other states rely primarily or exclusively on voluntary pooling of lands
and leases. In areas where pooling is voluntary, it may be more difficult to
form units, and therefore, more difficult to develop a project if the operator
owns less than 100 percent of the leasehold.

     In addition, some states have conservation laws that establish maximum
rates of production from natural gas reservoirs and impose some requirements
regarding the ratability of production. The effect of these regulations may
limit the amount of natural gas we can produce from our wells and may limit the
number of wells or the locations at which we can drill. The regulatory burden on
the natural gas industry increases our cost of doing business and, consequently,
affects our profitability. Inasmuch as laws and regulations are frequently
expanded, amended, and reinterpreted, we are unable to predict the future cost
or impact of complying with regulations.

     Regulation of Sales and Transportation of Natural Gas. Historically, the
transportation and resale of natural gas in interstate commerce have been
regulated by the Natural Gas Act of 1938, the Natural Gas Policy Act of 1978,
and the regulations promulgated by the Federal Energy Regulatory Commission.
Maximum selling prices of some categories of natural gas sold in "first sales,"
whether sold in interstate or intrastate commerce, were regulated under the
NGPA. The Natural Gas Well Head Decontrol Act removed, as of January 1, 1993,
all remaining federal price controls from natural gas sold in "first sales" on
or after that date. FERC's jurisdiction over natural gas transportation was
unaffected by the Decontrol Act. While sales by producers of natural gas and all
sales



                                       16
<PAGE>

of crude oil, condensate and natural gas liquids can currently be made at market
prices, Congress could reenact price controls in the future.

     Our sales of natural gas are affected by the availability, terms and cost
of transportation. The price and terms for access to pipeline transportation are
subject to extensive regulation. In recent years, FERC has undertaken various
initiatives to increase competition within the natural gas industry. As a result
of initiatives like FERC Order No. 636, issued in April 1992, the interstate
natural gas transportation and marketing system has been substantially
restructured to remove various barriers and practices that historically limited
non-pipeline natural gas sellers, including producers, from effectively
competing with interstate pipelines for sales to local distribution companies
and large industrial and commercial customers. The most significant provisions
of Order No. 636 require that interstate pipelines provide transportation
separate or "unbundled" from their sales service, and require that pipelines
make available firm and interruptible transportation service on an open access
basis that is equal for all natural gas suppliers.

     In many instances, the result of Order No. 636 and related initiatives has
been to substantially reduce or eliminate the interstate pipelines' traditional
role as wholesalers of natural gas in favor of providing only storage and
transportation services. Another effect of regulatory restructuring is the
greater transportation access available on interstate pipelines. In some cases,
producers and marketers have benefited from this availability. However,
competition among suppliers has greatly increased and traditional long-term
producer pipeline contracts are rare. Furthermore, gathering facilities of
interstate pipelines are no longer regulated by FERC, thus allowing gatherers to
change higher gathering rates.

     Additional proposals and proceedings that might affect the natural gas
industry are nearly always pending before Congress, FERC, state commissions and
the courts. The natural gas industry historically has been very heavily
regulated; therefore, we cannot be certain that the less stringent regulatory
approach recently pursued by FERC and Congress will continue. We cannot
determine to what extent our future operations and earnings will be affected by
new legislation, new regulations, or changes in existing regulations, at the
federal, state or local levels.

     Environmental Regulations. Our anticipated operations are subject to
additional laws and regulations governing the discharge of materials into the
environment or otherwise relating to environmental protection. Public interest
in the protection of the environment has increased dramatically in recent years.
The trend of more expansive and stricter environmental legislation and
regulations could continue. To the extent laws are enacted or other governmental
action is taken that restrict drilling or impose environmental protection
requirements that result in increased costs to the natural gas industry in
general, our business and prospects could be adversely affected.

     We generate wastes that may be subject to the Federal Resource Conservation
and Recovery Act ("RCRA") and comparable state statutes. The U.S. Environmental
Protection Agency and various state agencies have limited the approved methods
of disposal for some hazardous wastes. Furthermore, some wastes generated by our
operations that are currently exempt from treatment as "hazardous wastes" may in
the future be designated as "hazardous wastes," and therefore be subject to more
rigorous and costly operating and disposal requirements.

     We currently own or lease properties that for many years have been used for
the exploration and production of oil and natural gas.  Although we believe that
we have utilized good operating and waste disposal practices, prior owners and
operators of these properties may not have utilized similar practices, and
hydrocarbons or other wastes may have been disposed of or released on or under
the properties owned or leased by us or on or under locations where wastes have
been taken for disposal.  These properties and the wastes disposed on the
properties may be subject to the Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA"), RCRA and analogous state laws as well
as state laws governing the management of oil and natural gas wastes.  Under
those laws, we could be required to remove or remediate previously disposed
wastes, including waste disposed of or released by prior owners or operators, or
property contamination, including groundwater contamination, or to perform
remedial plugging operations to prevent future contamination.

     CERCLA and similar state laws impose liability, without regard to fault or
the legality of the original conduct, on some classes of persons that are
considered to have contributed to the release of a "hazardous substance" into
the environment.  These persons include the owner or operator of the disposal
site or sites where the release occurred and companies that disposed of or
arranged for the disposal of the hazardous substances found at the site.
Persons who are or were responsible for release of hazardous substances under
CERCLA may be subject to



                                       17
<PAGE>

joint and several liability for the costs of cleaning up the hazardous
substances that have been released into the environment and for damages to
natural resources, and it is not uncommon for neighboring landowners and other
third parties to file claims for personal injury and property damage allegedly
caused by the hazardous substances released into the environment.

     Our anticipated operations may be subject to the Clean Air Act and
comparable state and local requirements.  Amendments to the CAA were adopted in
1990, and contain provisions that may result in the gradual imposition of
pollution control requirements with respect to air emissions from our
operations.  The EPA and the states have been developing regulations to
implement these requirements.  We may be required to incur capital expenditures
in the next several years for air pollution control equipment in connection with
maintaining or obtaining operating permits and approvals addressing other air
emission related issues.

Employees

     As of August 31, 2001, we had one full-time employee and no part time
employees.  Our employee is not covered by a collective bargaining agreement,
nor do we anticipate that any of our future employees will be so covered.  If
our operations continue to grow as expected, we anticipate hiring as many as
three additional employees over the next six to eight months.

Facilities

     We currently share on a rent free basis approximately 3,400 square feet of
office space provided by Moose Oil & Gas Company in Houston, Texas as our
executive offices.  As we add employees and expand our business over the next
six to eight months, we anticipate that we will need to lease new space for our
executive offices.

Legal Proceedings

     As of the date of this prospectus/information statement, we are not
involved in any legal proceedings.


                    TEXAS NEVADA OIL & GAS CO. MANAGEMENT'S
                           DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATION

     Since 1992, TNOG has not conducted any material business activities.  From
1981 to 1991, TNOG held and operated all of the mineral interests of Unicorp,
Inc. in the State of Texas.  TNOG has not had any revenues after 1991, when it
ceased operations and began liquidating its operating assets.  Beginning in
1992, TNOG's activities have consisted primarily of maintaining its corporate
status through filing franchise tax returns and paying franchise taxes in the
State of Texas.  TNOG currently has only nominal assets.

                                  THE MERGER

     This section of the prospectus/information statement describes material
aspects of the proposed merger, including the agreement between TNOG and Houston
American relating to the merger.  While we believe that the description covers
the material terms of the merger, this summary may not contain all of the
information that is important to you.  You should read this entire document and
the other documents we refer to carefully for a more complete understanding of
the merger.

Background of the Merger


     On March 23, 2001, Opportunity Acquisition Company, a Texas corporation
which was wholly owned by John F. Terwilliger, our sole director and executive
officer, entered into an agreement with Unicorp, Inc., a Nevada corporation,
Equitable Assets Incorporated, a Belize corporation and the controlling
shareholder of Unicorp, and TNOG, a wholly owned subsidiary of Unicorp, a public
company, relating to merger of TNOG with and into Opportunity Acquisition
Company following the spin-off of TNOG's common stock to the shareholders of




                                       19
<PAGE>


Unicorp. Mr. Terwilliger learned of the possibility of merging TNOG and
Opportunity Acquisition Company from Mr. Norman T. Reynolds, our legal counsel.
Mr. Reynolds previously represented Unicorp and was aware of Unicorp's desire to
spin-off TNOG in a transaction of this nature. Other than the relationships
described in this paragraph, there is no affiliation between Houston American,
Opportunity Acquisition Company and John F. Terwilliger and the other parties to
the March Agreement, TNOG, Unicorp and Equitable Assets Incorporated.

     The terms of the March Agreement were negotiated by John F. Terwilliger, in
his capacity as the then president of Opportunity Acquisition Company, and Louis
G. Mehr, the president of TNOG and Unicorp.  As a result of those negotiations,
Messrs. Terwilliger and Mehr agreed that Opportunity Acquisition Company would
pay up to $75,000 of Unicorp's expenses in connection with the spin-off of TNOG
and TNOG's shareholders would receive an aggregate of five percent of the issued
and outstanding capital stock of Opportunity Acquisition Company, after giving
effect to the merger.  As a result of the merger of Opportunity Acquisition
Company with and into Houston American on April 12, 2001, which was solely
completed in order to cause the surviving public company in the anticipated
merger with TNOG to be a Delaware corporation, Houston American succeeded to the
rights and obligations of Opportunity Acquisition Company under the terms of the
March agreement.

     Prior to the merger, Unicorp will spin-off shares of TNOG's common stock to
Unicorp's stockholders as a dividend.  Unicorp has registered the TNOG common
stock under the Exchange Act by filing a Form 10-SB, which became effective in
September 2001.  Since the effective date of the Form 10-SB, TNOG has been a
fully reporting company under the Exchange Act.

     On July 31, 2001, we entered into an Plan and Agreement of Merger with
TNOG, whereby the companies memorialized the terms of the merger of TNOG with
and into Houston American as previously defined in the March agreement. Due to
the completion of the forward split of our common stock on an approximate 11.4
for one basis on September 25, 2001, the Plan and Agreement of Merger was
amended and restated as of September 26, 2001. The Amended and Restated Plan and
Agreement of Merger is attached to this prospectus/information statement as
Appendix A and is incorporated herein by this reference.
----------

     Upon the effectiveness of the merger, we will be the surviving entity, the
separate existence of TNOG will cease, and we will succeed to all of TNOG's
rights and properties and shall be subject to all of TNOG's debts and
liabilities.  Additionally, as TNOG's successor, we will succeed to its status
as a fully reporting public company under the Exchange Act.  Prior to the
delivery of this prospectus/information statement, the completion of the merger
was approved by the consent of a majority of TNOG's shareholders and over two-
thirds of our stockholders, subject to completion, filing and effectiveness of
the registration statement of which this prospectus/information statement is a
part.

Texas Nevada Oil & Gas Co.'s Reasons for the Merger

     TNOG's management believes that the merger will enable TNOG's shareholders
to realize an increase in the value of their original investment in Unicorp,
Inc. due to Houston American's ongoing oil and gas exploration and production
activities.  Over the last several years, there has been very little business
activity in Unicorp, Inc. and no business activity with respect to TNOG, despite
attempts to generate significant opportunities for both companies. The
management of both Unicorp and TNOG concluded that the proposed merger with
Houston American provided the best prospect to establish value for their
shareholders.

Our Reasons for the Merger

     Our management believes that our stockholders will benefit from the merger
because Houston American will obtain TNOG's relatively large shareholder base
which could be useful in helping us develop a public market for our common stock
by providing the necessary float of publicly held shares.  Due to the recent
downturn in the economy, it has become increasingly more difficult for companies
without a public exit vehicle to raise additional capital in private placements.
Therefore, developing a public market for our common stock is expected to
provide Houston American with greater access to additional financing from public
and private sources should it be necessary to obtain additional outside capital
in the future.  The registration of shares for resale of certain of our existing
stockholders will also provide an exit strategy for them.  Without the merger
with TNOG and the acquisition of its shareholder base, there would be no
meaningful market for the resale of our stock.  In the opinion of our


                                       20
<PAGE>

management, the anticipated benefits of becoming a public company far outweigh
the reporting and disclosure burdens associated with becoming a public
company.

     The foregoing discussion is not exhaustive of all of the factors considered
by our board of directors and TNOG's board of directors in deciding to approve
the merger.  Each director may have considered different factors, and the boards
evaluated these factors as a whole and did not qualify or otherwise assign
relative weights to the factors considered.

Completion and Effectiveness of the Merger

     The merger will be completed upon the filing of the necessary certificates
with the Secretary of State of Texas and the Secretary of State of Delaware,
which will not be prior to 20 days after the effectiveness of the registration
statement of which this prospectus/information statement is a part and the
notification of TNOG's shareholders.

Exchange of the TNOG Common Stock

     Upon completion of the merger, each outstanding share of TNOG common stock
will be exchanged for one share of our common stock.  After the merger is
complete, the certificates representing the shares of TNOG common stock
currently own by TNOG's shareholders should be sent to the transfer agent, with
any required documentation, in exchange for new certificates representing the
shares of our common stock to be issued as a result of the merger.

Material United States Federal Income Tax Consequences of the Merger

     The following are the material United States federal income tax
consequences of the merger.  The following discussion is based on and subject to
the Internal Revenue Code of 1986, the regulations promulgated thereunder,
existing administrative interpretations and court decisions and any related
laws, all of which are subject to change, possibly with retroactive effect.  The
following discussion assumes you hold your current shares of TNOG common stock
as capital assets within the meaning of Section 1221 of the Code.  This
discussion does not address all aspects of United States federal income taxation
that may be important to you in light of your particular circumstances or if you
are subject to special rules, such as rules relating to:

     .    shareholders who are not citizens or residents of the United States;

     .    financial institutions;

     .    tax exempt organizations;

     .    insurance companies; and

     .    dealers in securities.

     Our tax counsel has concluded that the merger will not qualify as a tax-
free reorganization and accordingly it will be a taxable transaction.  It is
likely that the Internal Revenue Service will characterize the transaction as if
TNOG sold all of its assets to us in a taxable transaction in exchange for our
stock, any cash paid to any shareholders of TNOG and the assumption of
liabilities of TNOG, and that TNOG subsequently distributed such stock and cash
to its shareholders in exchange for their TNOG shares.  If the merger is
considered this way, it will have the following federal income tax consequences:

     .    TNOG will recognize gain for federal income tax purposes equal to the
          difference between (i) the fair market value of our stock and any cash
          delivered to TNOG shareholders in connection with the merger, plus the
          liabilities of TNOG; and (ii) TNOG's adjusted basis of its assets.

     .    The TNOG shareholders will recognize gain or loss equal to the
          difference between (i) the fair market value of our common stock
          received by them and any cash received in connection with the merger,
          and (ii) their tax basis of their shares of TNOG.



                                       21
<PAGE>

     .    The tax basis of our common stock received by TNOG shareholders in the
          merger will equal the fair market value of the shares at the date the
          TNOG shareholders own the shares.

     .    The holding period for the shares of our common stock received by TNOG
          shareholders will not include the holding period of their TNOG shares.

     .    Houston American shareholders will not recognize gain or loss as a
          result of the merger.

     The foregoing discussion is not based upon an advance ruling by the United
States Treasury Department but upon an opinion of Jackson Walker LLP, counsel to
Houston American, which is attached as an exhibit to the registration statement
of which this prospectus/information statement is a part.  The foregoing
discussion is not intended to be a complete analysis or description of all
potential United States federal income tax consequences or any other
consequences of the merger.  In addition, the discussion does not address tax
consequences which may vary with, or are contingent on, your individual
circumstances.  Moreover, this discussion does not address any non-income tax or
any foreign, state or local tax consequences of the merger.  Accordingly, we
strongly urge you to consult with your tax adviser to determine the particular
United States federal, state, local or foreign income or other tax consequences
to you of the merger.

Regulatory Filings and Approvals Required to Complete the Merger

     We are not aware of any material governmental or regulatory approval
required for completion of the merger, other than compliance with the applicable
corporate laws of the States of Texas and Delaware.


                            DISSENTERS' RIGHTS

     Under Texas law, TNOG's shareholders are entitled, after complying with
certain requirements of Texas law, to dissent to the approval of the merger,
pursuant to Article 5.11 of the Texas Business Corporation Act, and to be paid
the "fair value" of their shares of TNOG common stock in cash by complying with
the procedures set forth in Articles 5.12 and 5.13 of the Texas Business
Corporation Act.  Set forth below is a summary of the procedures relating to the
exercise of dissenters' rights by TNOG's shareholders.  This summary does not
purport to be a complete statement of the provisions of Articles 5.11, 5.12 and
5.13 of the Texas Business Corporation Act and is qualified in its entirety by
reference to Articles 5.11, 5.12 and 5.13 of the Texas Business Corporation Act,
which are attached as Appendix B to this prospectus/information statement.
                      ----------

     Within 10 days after the effective date of the merger, we will deliver a
written dissenters' notice to each of TNOG's shareholders of record.  The
dissenters' notice must:

     .    notify the shareholder of the effective date of the merger; and

     .    be accompanied by a copy of Articles 5.11, 5.12, and 5.13 of the Texas
          Business Corporation Act.

     Any TNOG shareholder who did not consent to the merger can exercise his
dissenters' rights by making written demand on us, within 20 days after the
mailing of the dissenters' notice, for payment of the fair value of his shares
of TNOG common stock.  The shareholder's demand must state:

     .    the number of shares of TNOG common stock owned by the dissenting
          shareholder; and

     .    the fair value of the shares, as of the date of the consent approving
          the merger, as estimated by the shareholder.

     Any shareholder failing to make demand within the 20-day period will be
bound by the merger and will lose his right to be paid the fair value of his
shares.  Within 20 days after receipt of a demand for payment, we will deliver
or mail to the shareholder a written notice that shall either:



                                       22
<PAGE>

     .    set out that we accept the amount claimed by the shareholder and agree
          to pay that amount within 90 days after the action was effected,
          provided the shareholder has surrendered the certificates representing
          the shareholder's shares of TNOG common stock; or

     .    contain our estimate of the fair value of the shares, together with an
          offer to pay our estimate within 90 days after the action was
          effected, upon receipt of notice within 60 days after that date from
          the shareholder that the shareholder agrees to accept our estimate,
          provided the shareholder has surrendered the certificates representing
          the shareholder's shares of TNOG common stock.

     If we are unable to agree upon the fair value of any shareholder's shares
of TNOG common stock within 60 days of the date the merger was effected, either
party may, within 60 days of the expiration of such 60 day period, file a
petition in any court of competent jurisdiction in Harris County, Texas asking
for a finding and determination of the fair value of the shareholder's shares of
TNOG common stock.  Upon the filing of a petition by a TNOG shareholder, we are
required to file, within 10 days of service, a list containing the names and
addresses of all of TNOG's shareholders who have demanded payment and with whom
agreements as to the value of their shares have not been reached.  If we file a
petition, we must file the applicable shareholder list at the same time as the
petition.  If necessary, we shall, within 90 days of the court's determination
of fair value and upon surrender of the applicable certificates representing the
TNOG common stock, pay the applicable shareholders the fair value of their
respective shares.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Our oil and gas properties were purchased, at cost, from Moose Oil & Gas
Company, a Texas corporation and an affiliate of John F. Terwilliger, our sole
director and executive officer.  As payment for the properties, we issued Moose
Oil & Gas a promissory note in the amount of $216,981.  The note bears interest
at a rate of 10 percent per annum and is due on demand.  Our payment of the note
is secured by our interests in our oil and gas properties.  Should we fail to
make any required payment or otherwise default on the note, Moose Oil & Gas
would have the right to foreclose on our interests in our oil and gas
properties, which would have a materially adverse effect on our ability to
conduct our business.

     On April 6, 2001, we entered into an Operating Agreement with Moose
Operating Co., Inc., a Texas corporation and a subsidiary of Moose Oil & Gas.
The following summary of the material terms of the Operating Agreement is
qualified in its entirety by reference to the Operating Agreement, which is
attached as an exhibit to the registration statement of which this
prospectus/information statement is a part.

     Under the terms of the Operating Agreement, Moose Operating has full
control over the drilling activities to be conducted on our current leaseholds
in Lavaca County, Texas.  The Operating Agreement initially obligated Moose
Operating to commence drilling the first of our test wells prior to March 31,
2001, which Moose Operating completed timely.  Although Moose Operating is
initially responsible for the payment of all costs associated with  development
and operation, we, along with Moose Oil & Gas, are ultimately responsible for
our proportionate share of the costs based on our respective working interests.
Our respective share of the anticipated costs under the Operating Agreement are
discussed above in "Houston American Energy Corp. Management's Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources."

     In order to secure repayment of the costs, the Operating Agreement grants
Moose Operating a security interest in our proportionate share of the oil or gas
produced from any wells.  In addition to being entitled to utilize and receive
payment for the use of its own equipment and labor in conducting the operations,
the Operating Agreement entitles Moose Operating to receive monthly fixed
overhead payments of $4,500 per well being drilled and $500 per producing well.

     This summary of the material similarities and differences in the
corporation laws of Texas and Delaware, TNOG's amended Articles of Incorporation
and amended and restated Bylaws and our Certificate of Incorporation and Bylaws
does not purport to be a complete listing of the differences in the rights and
remedies of holders of shares of a Texas corporation as opposed to a Delaware
corporation and TNOG's shareholders and our stockholders in particular.  The
differences can be determined in full by reference to Texas law, Delaware law,
TNOG's amended Articles of Incorporation and amended and restated Bylaws and our
Certificate of Incorporation and Bylaws.

                  INDEMNIFICATION AND LIMITATION OF LIABILITY

     As permitted by the Delaware General Corporation Law, our certificate of
incorporation includes, subject to the limitations described below, a provision
that would limit or eliminate our directors' liability for monetary damages for
breaches of their fiduciary duties.  A director's liability cannot be limited or
eliminated for:

     .    breaches of the duty of loyalty;

     .    acts or omissions not in good faith or that involve intentional
          misconduct or a knowing violation of law;

     .    the payment of unlawful dividends or expenditure of funds for unlawful
          stock purchases or redemptions; or

     .    transactions from which the director derived an improper personal
          benefit.

     In addition, the limitation of liability provisions may not restrict a
director's liability for violation of, or otherwise relieve the corporation or
its directors from, the necessity of complying with federal or state securities
laws or affect the availability of nonmonetary remedies such as injunctive
relief or rescission.

     Our certificate of incorporation provides that we shall, to the extent
legally permissible, indemnify each of our former or present directors or
officers against all liabilities and expenses imposed upon or incurred by any of
them in connection with, or arising out of, the defense or disposition of any
action, suit or other proceeding, civil or criminal, in which he may be
threatened or involved, by reason of his having been a director or officer, if
it is determined that he acted in good faith and reasonably believed:

     .    in the case of conduct in his official capacity on our behalf that his
          conduct was in our best interests;

     .    in all other cases, that his conduct was not opposed to our best
          interests; and

     .    with respect to any proceeding which is a criminal action, that he had
          no reasonable cause to believe his conduct was unlawful.

     The termination of any proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself be determinative of whether the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to our best
interests, and, with respect to any proceeding which is a criminal action, had
no reasonable cause to believe that his conduct was unlawful.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling Houston American
pursuant to the foregoing provisions, or otherwise, we are aware that, in the
opinion of the SEC, such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable.

                       INTERESTED DIRECTOR TRANSACTIONS

     Under Delaware law, certain contracts or transactions between a corporation
and one or more of its directors or officers, or between a Delaware corporation
and any other corporation, partnership, association or other organization in
which one or more of its directors or officers, are directors or officers, or
have a financial interest, is


                                       31
<PAGE>

not void or voidable solely for that reason, or solely because the interested
director or officer was present at or participates in the board or board
committee meeting that authorizes the contract or transaction, or solely because
the director's or officer's votes are counted for that purpose, if:

     .    the material facts as to the director's or officer's relationship or
          interest and as to the contract or transaction are disclosed or known
          to the board of directors or committee, and the board or committee in
          good faith authorizes the contract or transaction by the affirmative
          votes of a majority of the disinterested directors, even though the
          disinterested directors constitute less than a quorum; or

     .    the material facts as to the director's or officer's relationship or
          interest and as to the contract or transaction are disclosed or known
          to the stockholders entitled to vote on the contract or transaction,
          and the contract or transaction is specifically approved in good faith
          by vote of the stockholders; or

     .    the contract or transaction is fair as to the corporation as of the
          time it is authorized, approved or ratified by the board of directors,
          a board committee or the stockholders.

                             PLAN OF DISTRIBUTION

     All securities referenced above under "Selling Stockholders" may be offered
by the identified stockholders from time to time on the OTC Bulletin Board in
privately negotiated sales or on other markets.  We believe that virtually all
of such sales will occur in transactions at prevailing market rates.  Any
securities sold in brokerage transactions will involve customary brokers'
commissions.  No underwriters will participate in any such sales on behalf of
the selling stockholders.

                          AUDITED FINANCIAL STATEMENTS

                          INDEPENDENT AUDITORS REPORT

Houston American Energy Corp.
Houston, Texas

We have audited the accompanying balance sheet of Houston American Energy Corp.
(a development stage company) as of April 15, 2001, and the related statement of
loss, stockholders' deficit, and cash flows for the period from April 2, 2001
(date of inception), to April 15, 2001. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the over-all
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects the financial position of Houston American Energy Corp. as
of April 15, 2001, and the results of its operations and its cash flows from
April 2, 2001 (date of inception), to April 15, 2001, in conformity with
accounting principles generally accepted in the United States of America.

The Company is in the development stage as of April 15, 2001. As discussed in
Note 2 to the financial statements, successful completion of the Company's fund
raising activities and, ultimately, the attainment of profitable operations is
dependent upon future events, including obtaining adequate financing to fulfill
its development activities and achieving a level of revenue adequate to support
the Company's cost structure.

                         HOUSTON AMERICAN ENERGY CORP.
                          A DEVELOPMENT STAGE COMPANY
                       NOTES TO THE FINANCIAL STATEMENTS
           FROM APRIL 2, 2001 (DATE OF INCEPTION) TO APRIL 15, 2001
           --------------------------------------------------------

NOTE 1. - NATURE OF COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Houston American Energy Corp. (a Delaware Corporation) ("the Company") was
incorporated on April 2, 2001.  The Company was organized to engage in the
exploration, development and acquisition of domestic oil and gas properties
principally in the State of Texas.


The Company completed a stock split as of September 25, 2001, which resulted in
total outstanding shares of 11,403,414. The Company has retroactively applied
this stock split to all share amounts and per share amounts in these financial
statements and footnotes.

Oil and Gas Revenues Receivables - The Company recognizes oil and gas revenue
--------------------------------
from its interest in producing wells as oil and gas is produced and sold from
those wells.  The Company does not anticipate that the oil and gas sold will be
significantly different from the Company's production entitlement.

Oil and Gas Properties and Equipment - The Company follows 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.  Gains 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 April 15, 2001.

The capitalized costs of oil and gas properties, plus estimated future
development costs relating to proved reserves are amortized on a unit-of-
production method over the estimated productive life of the proved oil and gas
reserves.  Unevaluated oil and gas properties are excluded from this
calculation.  As of April 15, 2001, the Company has not had any oil and gas
revenue, therefore, no amortization of the capitalized cost is necessary.

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 at prices in effect as of the balance
sheet date (with consideration of price changes only to the extent provided by
contractual arrangements) 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.  Excess costs are
charged to proved properties impairment expense.

Unevaluated Oil and Gas Properties - Unevaluated oil and gas properties consist
----------------------------------
principally of the Company's acquisition costs in 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 depletable oil and gas
properties.  Additionally, the Company reviews 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.  The Company records an allowance for impairment
based on the review with the corresponding charge being made to depletable oil
and gas properties.  There is no such allowance for impairment presented in the
accompanying financial statements.

Unevaluated oil and gas properties not subject to amortization include the
following:

          Acquisition costs            $155,730
                                       ========

                         HOUSTON AMERICAN ENERGY CORP.
                          A DEVELOPMENT STAGE COMPANY
                       NOTES TO THE FINANCIAL STATEMENTS
           FROM APRIL 2, 2001 (DATE OF INCEPTION) TO APRIL 15, 2001
           --------------------------------------------------------

NOTE 1. - NATURE OF COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES,
continued...

The Company anticipates that approximately $31,000 representing the acquisition
cost of an oil and gas property in Lavaca County, Texas will be moved to the
cost subject to amortization within the next three months.  The balance of
approximately $125,000 is for another oil and gas property in Lavaca County,
Texas.  The Company is maintaining this property and anticipates a well will be
drilled within the next twelve months.

Deferred Assets - Deferred assets consist of expenditures associated with a
---------------
potential merger discussion in Note 7.

Accrued Liabilities - Accrued liabilities consisted of attorneys fees.
-------------------


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 carryforwards.  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.

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.

Statement of Cash Flows - Cash equivalents consists of demand deposits and cash
-----------------------
investments with initial maturity dates of less than three months.  The Company
paid no interest or taxes during the period of the accompanying financial
statements.

Net Loss Per Share - Basic loss per share is computed by dividing the net loss
------------------
available to the common shareholders by the weighted average of common shares
outstanding during the period, as retroactively adjusted by the stock split
described in the second paragraph of Note 1.

Use of Estimates - The preparation of financial statements in conformity with
----------------
generally accepted accounting principles requires the Company to make estimates
and assumptions that could affect certain reported amounts and disclosures.
Accordingly, actual results could differ from those estimates.

NOTE 2. - DEVELOPMENT STAGE

The Company is in the development stage and does not have any revenue to support
its operations.  It is dependent on an affiliated entity to fund its operations
and costs associated with the acquisition, exploration and development of oil
and gas properties.  Management intends to obtain funds through private and/or
public securities offerings.  In the event that the affiliated entities ceases
to fund the Company's operations, the oil and gas properties would be used to
reduce the amounts due the affiliates.

NOTE 3. - NOTES PAYABLE

Notes payable at April 15, 2001, in the amount of $216,981, is due to an
affiliated company. The note bears interest at 10%, is due on demand for
principal and interest and is secured by all the oil and gas properties owned by
the Company.

                          A DEVELOPMENT STAGE COMPANY
                       NOTES TO THE FINANCIAL STATEMENTS
      FROM APRIL 2, 2001 (DATE OF INCEPTION) TO JUNE 30, 2001 (UNAUDITED)
      -------------------------------------------------------------------

NOTE 1. - NATURE OF COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Houston American Energy Corp. (a Delaware Corporation) ("the Company") was
incorporated on April 2, 2001.  The Company was organized to engage in the
exploration, development and acquisition of domestic oil and gas properties
principally in the State of Texas.

The Statement of Loss and Shareholders' Deficit Accumulated in Development Stage
for the period from April 2, 2001 (Date of Inception) to June 30, 2001, the
Statement of Cash Flows for the period April 2, 2001 (Date of Inception) to June
30, 2001, and the Balance Sheet as of June 30, 2001 include, in the opinion of
management, all of the adjustments necessary, consisting only of normal
recurring adjustments, for a fair presentation of the results for this period
and the financial condition as of that date.  Historical interim results are not
necessarily indicative of results that may be expected for any future period.


The Company completed a stock split as of September 25, 2001, which resulted in
total outstanding shares of 11,403,414. The Company has retroactively applied
this stock split to all share amounts and per share amounts in these financial
statements and footnotes.

Oil and Gas Revenues Receivables - The Company recognizes oil and gas revenue
--------------------------------
from its interest in producing wells as oil and gas is produced and sold from
those wells.  The Company does not anticipate that the oil and gas sold will be
significantly different from the Company's production entitlement.


Oil and Gas Properties and Equipment - The Company follows 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 June 30, 2001.

The capitalized costs of oil and gas properties, plus estimated future
development costs relating to proved reserves are amortized on a unit-of-
production method over the estimated productive life of the proved oil and gas
reserves.  Unevaluated oil and gas properties are excluded from this
calculation.  As of June 30, 2001, the Company has not had any oil and gas
revenue, therefore, no amortization of the capitalized cost is necessary.

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 at prices in effect as of the balance
sheet date (with consideration of price changes only to the extent provided by
contractual arrangements) 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.  Excess costs are
charged to proved properties impairment expense.

Unevaluated Oil and gas Properties - Unevaluated oil and gas properties consist
-----------------------------------
principally of the Company's acquisition costs in 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 depletable oil and gas
properties.  Additionally, the Company reviews 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.  The Company records an allowance for impairment
based on the review with the corresponding charge being made to depletable oil
and gas properties.  There is no such allowance for impairment presented in the
accompanying financial statements.

                          A DEVELOPMENT STAGE COMPANY
                       NOTES TO THE FINANCIAL STATEMENTS
      FROM APRIL 2, 2001 (DATE OF INCEPTION) TO JUNE 30, 2001 (UNAUDITED)
      -------------------------------------------------------------------

NOTE 1. - NATURE OF COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

continued . . .


Unevaluated oil and gas properties not subject to amortization include the
following:

          Acquisition costs            $155,730
                                       ========

The Company anticipates that approximately $31,000 representing the acquisition
cost of an oil and gas property in Lavaca County, Texas will be moved to the
cost subject to amortization within the next three months.  The balance of
approximately $125,000 is for another oil and gas property in Lavaca County,
Texas.  The Company is maintaining this property and anticipates a well will be
drilled within the next twelve months.

Deferred Assets - Deferred assets consist of expenditures associated with a
----------------
potential merger discussion in Note 7.

Accrued Liabilities - Accrued liabilities consisted of attorneys fees and other
-------------------
accrued expenditures.

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 carryforwards.  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.

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.

Statement of Cash Flows - Cash equivalents consists of demand deposits and cash
-----------------------
investments with initial maturity dates of less than three months.  The Company
paid no interest or taxes during the period of the accompanying financial
statements.


Net Loss Per Share - Basic loss per share is computed by dividing the net loss
-------------------
available to common shareholders by the weighted average of common shares
outstanding during the period, as retroactively adjusted by the stock split
described in the second paragraph of Note 1.

Use of Estimates - The preparation of financial statements in conformity with
-------------------
generally accepted accounting principles requires the Company to make estimates
and assumptions that could affect certain reported amounts and disclosures.
Accordingly, actual results could differ from those estimates.

NOTE 2. - DEVELOPMENT STAGE

The Company is in the development stage and does not have any revenue to support
its operations.  It is dependent on an affiliated entity to fund its operations
and cost associated with the acquisition, exploration and development of oil and
gas properties.  Management intends to obtain funds through private and/or
public securities offerings.  In the event, that the affiliated entities ceases
to fund the Company's operations, the oil and gas properties would be used to
reduce the amounts due the affiliates.

NOTE 3. - NOTES PAYABLE

Notes payable at June 30, 2001, in the amount of $216,981, is due to an
affiliated company.  The note bears interest at 10%, is due on demand for
principal and interest and is secured by all the oil and gas properties owned by
the Company.

                    from inception of the development stage,

                       Report of Independent Accountants

Board of Directors and Stockholder
Texas Nevada Oil & Gas Co.

We have audited the accompanying balance sheet of Texas Nevada Oil & Gas Co. (a
corporation in the development stage) as of December 31, 2000 and the related
statements of operations, stockholder's equity and cash flows for the two years
in the period then ended and for the period from inception of the development
stage, January 1, 1999, to December 31, 2000.  These financial statements are
the responsibility of the Company's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the 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 financial statements referred to above present fairly, in
all material respects, the financial position of Texas Nevada Oil & Gas Co. as
of December 31, 2000, and the results of its operations and its cash flows for
the two years in the period then ended and for the period from inception of the
development stage, January 1, 1999, to December 31, 2000, in conformity with
generally accepted accounting principles.

                   (A Corporation in the Development Stage)
                         NOTES TO FINANCIAL STATEMENTS
                         -----------------------------

1.   Description Of Business
     -----------------------

     Texas Nevada Oil & Gas Co. (the "Company") was incorporated on June 15,
     1981 in the state of Texas. The Company is a wholly-owned subsidiary of
     Unicorp, Inc. (the "Parent") and was originally formed for the purpose of
     holding and operating the Parent's mineral interests in the State of Texas.
     The Company has not been engaged in any significant activities since 1991
     when it ceased active operations and liquidated its operating assets. The
     Company is now considered a development stage enterprise because it has not
     yet commenced new commercial operations and because its current efforts are
     focused almost entirely on corporate structure and capital raising
     activities.

     The date of inception of the development stage of the Company for purposes
     of financial reporting is considered to be January 1, 1999, because on or
     about that date management began planning future activities for the dormant
     Company. Accordingly, in accordance with Statement of Financial Accounting
     Standards #1, Accounting and Reporting by Development Stage Enterprises,
                   ---------------------------------------------------------
     the accompanying financial statements include cumulative amounts from
     January 1, 1999, the inception of the development stage.

2.    Summary of Significant Accounting Policies
      ------------------------------------------

      Cash and Cash Equivalents
      -------------------------

      Cash and cash equivalents include all cash balances and any highly liquid
      short-term investments with an original maturity of three months or less.

      Income Taxes
      ------------

      The Company uses the asset and liability method of accounting for income
      taxes. Under the asset and liability method, deferred tax assets and
      liabilities are recognized for the estimated future tax consequences
      attributable to differences between the financial statement carrying
      amounts of existing assets and liabilities and their respective tax bases.
      This method also requires the recognition of future tax benefits such as
      net operating loss carryforwards, to the extent that realization of such
      benefits is more likely than not. Deferred tax assets and liabilities are
      measured using enacted tax rates expected to apply to taxable income in
      the years in which those temporary differences are expected to be
      recovered or settled. The effect on deferred tax assets and liabilities of
      a change in tax rates is recognized in income in the period that includes
      the enactment date.

      Net Loss Per Common Share
      -------------------------

      Basic and dilutive net loss per common share for the years ended December
      31, 2000 and 1999 have been computed by dividing net loss by the weighted
      average number of shares of common stock outstanding during these periods.

      Estimates
      ---------

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosure of contingent assets and liabilities at the date of the
      financial statements and the reported amounts of revenues and expenses
      during the reporting period. Actual results could differ from those
      estimates.

                         NOTES TO FINANCIAL STATEMENTS
                         -----------------------------

2.   Summary of Significant Accounting Policies, continued
     -----------------------------------------------------

     Fair Value of Financial Instruments
     -----------------------------------

     The Company includes fair value information in the notes to the financial
     statements when the fair value of its financial instruments is different
     from the book value. When the book value approximates fair value, no
     additional disclosure is made.

     Comprehensive Income
     --------------------

     The Company has adopted Statement of Financial Accounting Standard ("SFAS")
     No. 130, "Reporting Comprehensive Income". Comprehensive income includes
     such items as unrealized gains or losses on certain investment securities
     and certain foreign currency translation adjustments. The Company's
     financial statements include none of the additional elements that affect
     comprehensive income. Accordingly, comprehensive income and net income are
     identical.

     Segment Information
     -------------------

     The Company has adopted SFAS 131, "Disclosures About Segments of an
     Enterprise and Related Information". SFAS 131 requires a company to
     disclose financial and other information, as defined by the statement,
     about its business segments, their products and services, geographic areas,
     major customers, revenues, profits, assets and other information. The
     Company currently operates in only one business segment and does not have
     geographically diversified business operations.

3.   Income Taxes
     ------------

     The tax effects of temporary differences that give rise to deferred tax
     assets at December 31, 2000 are as follows:

          Net operating loss carryforward             $    150
                                                      --------

         Total gross deferred tax assets                   150

         Less valuation allowance                         (150)
                                                      --------
         Net deferred tax assets                      $      -
                                                      ========

4.   Subsequent Event
     ----------------

     On March 23, 2001, the Company entered into an agreement with the Parent,
     the controlling stockholder of the Parent, and Opportunity Acquisition
     Company ("Opportunity") under which the Company agreed to merge with
     Opportunity in a transaction (the "Transaction") that will be treated as a
     recapitalization of Opportunity. Under the Transaction, the parties agreed
     to the following:

     .    The Parent will "spin-off" the Company to its stockholders and
          promptly thereafter the Parent and the Company will register the
          Company's common stock on Form 10-SB in accordance with the Securities
          Exchange Act of 1934, as amended (the "Exchange Act").

      .   Following the completion of the spin-off and effective registration of
          the Company's common stock, Opportunity will merge (the "Merger") with
          the Company through the exchange of 5% of its common stock for 100% of
          the Company's common stock.

      .   The Company and the Parent will prepare and send to the stockholders
          of the Parent an information statement (the "Information Statement")
          required by the Exchange Act in connection with obtaining approval for
          the Merger.

4.   Subsequent Event, continued
     ---------------------------

     .   Opportunity, in connection with the Information Statement and as part
         of the merger, will prepare a registration statement on Form S-4 under
         the Securities Act of 1933 to register the Opportunity common stock
         received by the Company's stockholders.

     .   If the Company, the Parent and the controlling stockholder of the
         Parent comply with all requirements of the Transaction, Opportunity
         will pay up to $75,000 of the costs of the Transaction through
         cancellation of a $75,000 promissory note that was originated as part
         of the Transaction.

                NOTES TO UNAUDITED INTERIM FINANCIAL STATEMENTS
                -----------------------------------------------

1. Description of Business
   -----------------------

   Texas Nevada Oil & Gas Co. (the "Company") was incorporated on June 15, 1981
   in the state of Texas. The Company is a wholly-owned subsidiary of Unicorp,
   Inc. (the "Parent") and was originally formed for the purpose of holding and
   operating the Parent's mineral interests in the State of Texas. The Company
   has not been engaged in any significant activities since 1991 when it ceased
   active operations and liquidated its operating assets. The Company is now
   considered a development stage enterprise because it has not yet commenced
   new commercial operations and because its current efforts are focused almost
   entirely on corporate structure and capital raising activities.

   The date of inception of the development stage of the Company for purposes of
   financial reporting is considered to be January 1, 1999, because on or about
   that date management began planning future activities for the dormant
   Company. Accordingly, in accordance with Statement of Financial Accounting
   Standards #1, Accounting and Reporting by Development Stage Enterprises, the
                 ---------------------------------------------------------
   accompanying financial statements include cumulative amounts from January 1,
   1999, the inception of the development stage.

2. Interim Financial Statements
   ----------------------------

   The accompanying unaudited financial statements have been prepared in
   accordance with generally accepted accounting principles for interim
   financial information and with the instructions to Form 10-SB and Article 10
   of Regulation S-B. Accordingly, they do not include all of the information
   and footnotes required by generally accepted accounting principles for
   complete financial statements. In the opinion of management, all adjustments
   (consisting of normal recurring accruals) considered necessary for a fair
   presentation have been included. Operating results for the six months ended
   June 30, 2001 and 2000 are not necessarily indicative of the results that may
   be expected for the respective full years.

   A summary of the Company's significant accounting policies and other
   information necessary to understand these financial statements is presented
   in the Company's audited financial statements for the years ended December
   31, 2000 and 1999. Accordingly, the Company's audited financial statements
   should be read in connection with these financial statements.

3. Merger with Opportunity Acquisition Company
   -------------------------------------------

   On March 23, 2001, the Company entered into an agreement with the Parent, the
   controlling stockholder of the Parent, and Opportunity Acquisition Company
   ("Opportunity") under which the Company agreed to merge with Opportunity in a
   transaction (the "Transaction") that will be treated as a recapitalization of
   Opportunity. Under the Transaction, the parties agreed to the following:

   . The Parent will "spin-off" the Company to its stockholders and promptly
     thereafter the Parent and the Company will register the Company's common
     stock on Form 10-SB in accordance with the Securities Exchange Act of 1934,
     as amended (the "Exchange Act").

   . Following the completion of the spin-off and effective registration of the
     Company's common stock, Opportunity will merge (the "Merger") with the
     Company through the exchange of 5% of its common stock for 100% of the
     Company's common stock.

   . The Company and the Parent will prepare and send to the stockholders of the
     Parent an information statement (the "Information Statement") required by
     the Exchange Act in connection with obtaining approval for the Merger.

                -----------------------------------------------

3. Merger with Opportunity Acquisition Company, continued
   ------------------------------------------------------

   . Opportunity, in connection with the Information Statement and as part of
     the Merger, will prepare a registration statement on Form S-4 under the
     Securities Act of 1933 to register the Opportunity common stock received by
     the Company's stockholders.

   . If the Company, the Parent and the controlling stockholder of the Parent
     comply with all requirements of the Transaction, Opportunity will pay up to
     $75,000 of the costs of the Transaction through cancellation of a
     promissory note that will be funded as part of the Transaction.

     WHEREAS, in order to correct certain provisions of the Original Plan to
reflect the Split, TNOG and HAEC desire to amend and restate the Original Plan

immediately prior to the merger (the "Merger").

          (d)  The Surviving Corporation will be responsible for the payment of
all fees and franchise taxes of the constituent entities payable to the State of
Delaware and the State of Texas, if any.

undersigned, being of the age of 18 years or more and acting as the incorporator
of HOUSTON AMERICAN ENERGY CORP. (the "Company"), under the laws of the State of

Company shall have authority to issue is 110,000,000, consisting of 100,000,000

Stock").

     2.   Preferred Stock.  The Preferred Stock may be issued from time to time
          ---------------
in one or more series.  The Company's board of directors (the "Board of
Directors") is hereby authorized to create and provide for the issuance of
shares of Preferred Stock in series and, by filing a certificate pursuant to the
applicable section of the DGCL (the "Preferred Stock Designation"), to establish
from time to time the number of shares to be included in each such series, and
to fix the designations, powers, preferences and rights of the shares of each
such series and the qualifications, limitations or restrictions thereof.  The
authority of the Board of Directors with respect to each series shall include,
but not be limited to, determination of the following:

     (a)  The designation of the series, which may be by distinguishing number,
letter or title.

     (b)  The number of shares of the series, which number the Board of
Directors may thereafter (except where otherwise provided in the Preferred Stock

any other class or series, or any other security, of the Company or any other
corporation, and, if so, the specification of such other class or series of such
other security, the conversion price or prices or rate or rates, any adjustments
thereof, the date or dates at which such shares shall be convertible and all
other terms and conditions upon which such conversion may be made.

     (i)  Restrictions on the issuance of shares of the same series or of any
other class or series.

thereof as the Board of Directors shall determine.

     3.   Common Stock.  The Common Stock shall be subject to the express terms
          ------------
of the Preferred Stock and any series thereof.  Each share of the Common Stock
shall be equal to each other share of Common Stock.  The holders of shares of
the Common Stock shall be entitled to one vote for each such share upon all
questions presented to the stockholders.

     4.   Voting Rights.  Except as may be provided in this Certificate of
          -------------
Incorporation or in a Preferred Stock Designation, or as may be required by
applicable law, the Common Stock shall have the exclusive right to vote for the

stockholders at which they are not entitled to vote.  At each election for
directors every stockholder entitled to vote at such election shall have the
right to vote, in person or by proxy, the number of shares owned by him for as
many persons as there are directors to be elected and for whose election he has
a right to vote.  It is expressly prohibited for any stockholder to cumulate his
votes in any election of directors.

     5.   Denial of Preemptive Rights.  No stockholder of the Company shall by
          ---------------------------
reason of his holding shares of any class have any preemptive or preferential
right to purchase or subscribe to any shares of any class of the Company now or
hereafter to be authorized or any notes, debentures, bonds, or other securities
convertible into or carrying options or warrants to purchase shares of any
class, now or hereafter to be authorized, whether or not the issuance of any
such shares, or such notes, debentures, bonds or other securities would
adversely affect dividend or voting rights of such stockholder, other than such
rights, if any, as the Board of Directors in its discretion may fix; and the
Board of Directors may issue shares of any class of the Company, or any notes,
debentures, bonds, or other securities convertible into or carrying options or
warrants to purchase shares of any class, without offering any such shares of
any class, either in whole or in part, to the existing stockholders of any
class.

                                  ARTICLE VI
                             Election of Directors

     1.   Number.  The number of directors constituting the initial Board of
          ------
Directors of the Company is one.  The name and address of the person who is to
serve as the initial director until the first annual meeting of the
stockholders, or until his successor(s) have been elected and qualified is:

               Name                                    Address

        John F. Terwilliger                    801 Travis, Suite 1425
                                                Houston, Texas 77002

     The business and affairs of the Company shall be conducted and managed by,
or under the direction of, the Board of Directors.  The total number of
directors constituting the entire Board of Directors shall be fixed and may be
altered from time to time by or pursuant to a resolution passed by the Board of
Directors.

     2.   Classes of Directors.  The Board of Directors shall be divided into
          --------------------
three classes, Class A, Class B and Class C.  Such classes shall be as nearly
equal in number of directors as possible.  Each director shall serve for a term
expiring at the third annual meeting following the annual meeting at which such
director was elected; provided, however, that the directors first elected to
Class A shall serve for an initial term expiring at the annual meeting following
the end of the Company's 2001 fiscal year, the directors first elected to Class
B shall serve for an initial term expiring at the second annual meeting next
following the end of the Company's 2001 fiscal year, and the directors first
elected to Class C shall serve for an initial term expiring at the third annual
meeting next following the end of the Company's 2001 fiscal year.
Notwithstanding anything herein contained to the contrary, the person named in
subparagraph 1 of this Article VI shall be a Class C director.  Moreover, except
as otherwise provided in this Certificate of Incorporation or any Preferred
Stock Designation, directors who are elected at an annual meeting of
stockholders, and directors elected in the interim to fill vacancies and newly
created directorships, shall hold office for the term for which elected and
until their successors are elected and qualified or until their earlier death,
resignation or removal.  Whenever the holders of any class or classes of stock
or any series thereof shall be entitled to elect one or more directors pursuant
to any Preferred Stock Designation, and except as otherwise provided herein or
therein, vacancies and newly created directorships of such class or classes or
series thereof may be filled by a majority of the directors elected by such
class or classes or series thereof then in office, by a sole remaining director
so elected or by the unanimous written consent or the affirmative vote of a
majority of the outstanding shares of such class or classes or series entitled
to elect such director or directors.

     3.   Vacancies.  Except as otherwise provided for herein, newly created
          ---------
directorships resulting from any increase in the authorized number of directors,
and any vacancies on the Board of Directors resulting from death, resignation,
disqualification, removal or other cause, may be filled only by the affirmative
vote of a majority of the remaining directors then in office, even though less
than a quorum of the Board of Directors.  Any director elected in accordance
with the preceding sentence shall hold office for the remainder of the full term
of the newly created directorship or for the directorship in which the vacancy
occurred, and until such director's successor shall have been duly elected and
qualified, subject to his earlier death, disqualification, resignation or
removal.  Subject to the provisions of this Certificate of Incorporation, no
decrease in the number of directors constituting the Board of Directors shall
shorten the term of any incumbent director.

     4.   Removal of Directors.  Except as otherwise provided in any Preferred
          --------------------
Stock Designation, any director may be removed from office only by the
affirmative vote of the holders of two-thirds (2/3) or more of the combined
voting power of the then outstanding shares of capital stock of the Company
entitled to vote at a meeting of stockholders called for that purpose, voting
together as a single class.

                                  ARTICLE VII
                       Powers of the Board of Directors

     In furtherance and not in limitation of the powers conferred by statute,
the Board of Directors is expressly authorized:

     (a)  To authorize and cause to be executed mortgages and liens upon the
real and personal property of the Company.

<PAGE>

     (b)  To set apart out of any of the funds of the Company available for
dividends a reserve or reserves for any proper purpose and to abolish any such
reserve in the manner in which it was created.

     (c)  The Board of Directors may, by resolution adopted by a majority of the
whole Board, designate an Executive Committee, and one or more additional
committees, to exercise, subject to applicable provisions of law, such powers of
the Board of Directors in the management of the business and affairs of the
Company as set forth in said resolution, but no such committee shall have the
power or authority in reference to the following matters: (i) approving or
adopting, or recommending to the stockholders, any action or matter expressly
required to be submitted to the stockholders for approval or, (ii) adopting,
amending or repealing any Bylaw of the Company.  The Executive Committee and
each such other committee shall consist of two or more directors of the Company.
The Board of Directors may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee.  Any such committee may to the extent permitted by law
exercise such powers and shall have such responsibilities as shall be specified
in the designating resolution.  In the absence or disqualification of any member
of such committee or committees, the member or members thereof present at any
meeting and not disqualified from voting, whether or not constituting a quorum,
may unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.

     (d)  When and as authorized by the stockholders in accordance with law, to
sell, lease or exchange all or substantially all of the property and assets of
the Company, including its good will and its corporate franchises, upon such
terms and conditions and for such consideration, which may consist in whole or
in part of money or property including shares of stock in, and/or other
securities of, any other corporation or corporations, as its board of directors
shall deem expedient and for the best interests of the Company.

                                 ARTICLE VIII
                            Receivers and Trustees

     Whenever a compromise or arrangement is proposed between the Company and
its creditors or any class of them and/or between the Company and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of the Company or
of any creditor or stockholder thereof, on the application of any receiver or
receivers appointed for the Company under the provisions of Section 291 of the
DGCL or on the application of trustees in dissolution or of any receiver or
receivers appointed for the Company under the provisions of Section 279 of the
DGCL, order a meeting of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of the Company, as the case may be, to be
summoned in such manner as the said court directs.  If a majority in number
representing three-fourths in value of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of the Company, as the case
may be, agree to any compromise or arrangement and to any reorganization of the
Company as a consequence of such compromise or arrangement, the said compromise
or arrangement and said reorganization shall, if sanctioned by the court to
which the said application has been made, be binding on all the creditors or
class of creditors, and/or on all the stockholders or class of stockholders, of
the Company, as the case may be, and also on the Company.

                                  ARTICLE IX
                                    Bylaws

     Bylaws of the Company may be adopted, amended or repealed by the Board of
Directors or by the affirmative vote of the holders of a majority of the
Company's stock, outstanding and entitled to vote at the meeting at which any
Bylaw is adopted, amended or repealed.  Such Bylaws may contain any provision
for the regulation and management of the affairs of the Company and the rights
or powers of its stockholders, directors, officers or employees not inconsistent
with statute or this Certificate of Incorporation.

     The Company reserves the right to amend, alter, change or repeal any
provision contained in this Certificate of Incorporation, in the manner now or

                                  ARTICLE XII
                            Limitation of Liability

     A director of the Company shall not be personally liable to the Company or
its stockholders for monetary damages for breach of his fiduciary duty as a
director; provided, however, that this Article XII shall not eliminate or limit
the liability of a director: (a) for any breach of the director's duty of
loyalty to the Company or stockholders, (b) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the DGCL, or (d) for any transaction from which the
director derived an improper personal benefit.

     If the DGCL is amended after the date of filing of this Certificate of
Incorporation to authorize corporate action further limiting or eliminating the
personal liability of a director, then the liability of the directors of the
Company shall be limited or eliminated to the fullest extent permitted by the
DGCL, as so amended.  Any repeal or modification of this Article by the
stockholders of the Company or otherwise shall not adversely affect any right or
protection of a director of the Company existing at the time of such repeal or
modification.

                                 ARTICLE XIII
              Business Combinations with Interested Stockholders

may be indemnified, to the fullest extent permitted by Section 145 of the DGCL
("Section 145"), as it may be amended from time to time, in each and every
situation where the Company is obligated to make such indemnification pursuant
to Section 145.  In addition, the Company shall indemnify each of the Company's
directors and officers in each and every situation where, under Section 145, the
Company is not obligated, but is permitted or empowered, to make such
indemnification.  The Company may, in the sole discretion of the Board of
Directors, indemnify any other person who may be indemnified pursuant to Section
145 to the extent the Board of Directors deems advisable, as permitted by such
section.  The Company shall promptly make or cause to be made any determination
which Section 145 requires.

     No contract or transaction between the Company and one or more of its
directors or officers, or between the Company and any other corporation,
partnership, association, or other organization in which one or more of its
directors or officers, are directors or officers, or have a financial interest,
shall be void or voidable solely for this reason, or solely because the director

                            CERTIFICATE OF AMENDMENT
                                     TO THE
                          CERTIFICATE OF INCORPORATION
                                       OF
                         HOUSTON AMERICAN ENERGY CORP.

     Houston American Energy Corp., a corporation organized and existing under
and by virtue of the General Corporation Law of the State of Delaware (the
"Company"), does hereby certify that:

     FIRST:  The name of the Company is Houston American Energy Corp.

     SECOND:  The Board of Directors of the Company, acting pursuant to Section
141(f) of the Delaware General Corporation Law ("DGCL"), duly adopted a
resolution proposing the amendment to the Certificate of Incorporation of the
Company described below, declaring said amendment to be advisable and
recommending its approval to the stockholders of the Company for consideration
thereof, and the Company's stockholders have duly adopted such amendment in
accordance with Section 228 of the DGCL.

     THIRD:  The Certificate of Incorporation of the Company is hereby amended
to effect an 11.403431 for one stock split of the Company's outstanding shares
of common stock, par value $.001 per share, on the date hereof and immediately
before the filing of this Certificate of Amendment, by adding the following
language after the first paragraph of Article IV, Section 1:

"Simultaneously with the filing of this amendment (the "Effective Time"), each
share of Common Stock issued and outstanding immediately before the Effective
Time (such shares, the "Old Common Stock") shall automatically and without any
action on the part of the holder thereof, be split, subdivided and changed into
11.403431 shares of Common Stock (such shares, the "Common Stock").  The number
of shares of the Common Stock to be issued to each holder of Old Common Stock
shall be rounded to the nearest whole share.  In lieu of any fractional share to
which any such holder would be entitled, the Company shall pay such holder an
amount of cash equal to the fair value of such fractional share as of the
Effective Time.  Each holder of a certificate or certificates that immediately
before the Effective Time represented outstanding shares of the Old Common Stock
(the "Old Common Certificates") shall be entitled to receive, on surrender of
the Old Common Certificates to the Company's secretary for cancellation, a
certificate or certificates representing the number of shares of Common Stock
(the "Common Certificates") into which and for which the shares of the Old
Common Stock, formerly represented by the Old Common Certificates so
surrendered, are being split and subdivided under the terms hereof.  From and
after the Effective Time, the Old Common Certificates shall represent only the
right to receive the Common Certificates pursuant to the provisions hereof.  If
more than one Old Common Certificate shall be surrendered at one time for the
account of the same stockholder, the number of full shares of Common Stock for
which Common Certificates shall be issued shall be computed on the basis of the
aggregate number of shares represented by the Old Common Certificates so
surrendered."

     FOURTH:  The aforesaid amendment was duly adopted in accordance with the
provisions of Section 242 of the General Corporation Law of the State of
Delaware.

     IN WITNESS WHEREOF, the Company has caused this Certificate to be signed by
John F. Terwilliger, its President, this 24/th/ day of September, 2001.

          ----------------------------------------------

          A.  Annual Meetings of Stockholders.
              -------------------------------

              (1)   Nominations of persons for election to the Board of
Directors of the Company and the proposal of business to be considered by the
stockholders may be made at an annual meeting of stockholders (a) pursuant to
the Company's notice of meeting delivered pursuant to Paragraph 2.4 of these
Bylaws, (b) by or at the direction of the Board of Directors, or (c) by any
stockholder of the Company who is entitled to vote at the meeting, who complied
with the notice procedures set forth in clauses (2) and (3) of this Paragraph
2.7(A) and these Bylaws and who was a stockholder of record at the time such
notice is delivered to the Secretary of the Company.

              (2)   For nominations or other business to be properly brought
before an annual meeting by a stockholder pursuant to clause (c) of Paragraph
2.7(A)(1) of these Bylaws, the stockholder must have given timely notice thereof
in writing to the Secretary of the Company and such other business must
otherwise be a proper matter for stockholder action. To be timely, a
stockholder's notice shall be delivered to the Secretary at the principal office
of the Company not less than 70 days nor more than 90 days prior to the first
anniversary of the preceding year's annual meeting; provided, however, that in
the event that the date of an annual meeting is advanced by more than 30 days,
or delayed by more than 70 days, from the first anniversary date of the previous
year's annual meeting, notice by the stockholder to be timely must be so
delivered not earlier than the 90th day prior to such annual meeting and not
later than the close of business on the later of the 70th day prior to such
annual meeting or the 10th day following the day on which public announcement of
the date of such meeting is first made by the Company. Such stockholder's notice
shall set forth (a) as to each person whom the stockholder proposes to nominate
for election or reelection as a director all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
directors, or is otherwise required, in each case pursuant to Regulation 14A
under the Securities Exchange Act of 1934, as amended (the "Exchange Act") and
the regulations promulgated thereunder, including such person's written consent
to being named in the proxy statement as a nominee and to serving as a director
if elected; (b) as to any other business that the stockholder proposes to bring
before the meeting, a brief description of the business desired to be brought
before the meeting, the reasons for conducting such business at the meeting and
any material interest in such business of such stockholder and the beneficial
owner, if any, on whose behalf the proposal is made; and (c) as to the
stockholder giving the notice and the beneficial owner, if any, on whose behalf
the nomination or proposal is made (i) the name and address of such stockholder,
as they appear on the Company's books, and of such beneficial owner, and (ii)
the class and number of shares of the Company which are owned beneficially and
of record by such stockholder and such beneficial owner.

              (3)   Notwithstanding anything in the second sentence of Paragraph
2.7(A)(2) of these Bylaws to the contrary, in the event that the number of
directors to be elected to the Board of Directors of the Company is increased
and there is no public announcement by the Company naming all of the nominees
for director or specifying the size of the increased Board of Directors made by
the Company at least 80 days prior to the first anniversary of the preceding
year's annual meeting, a stockholder's notice required by these Bylaws shall
also be considered timely, but only with respect to nominees for any new
positions created by such increase, if it shall be delivered to the Secretary at
the principal office of the Company not later than the close of business on the
10th day following the day on which such public announcement is first made by
the Company.

          B.  Special Meetings of Stockholders.  Only such business shall be
              --------------------------------
conducted at a special meeting of stockholders as shall have been brought before
the meeting pursuant to the Company's notice of meeting pursuant to Paragraph
2.4 of these Bylaws.  Nominations of persons for election to the Board of
Directors may be made at a special meeting of stockholders at which directors
are to be elected pursuant to the Company's notice of meeting (a) by or at the

                                      A-13
<PAGE>

direction of the Board of Directors, or (b) by any stockholder of the Company
who is entitled to vote at the meeting, who complies with the notice procedures
set forth in these Bylaws and who is a stockholder of record at the time such
notice is delivered to the Secretary of the Company.  Nominations by
stockholders of persons for election to the Board of Directors may be made at
such a special meeting of stockholders if the stockholder's notice as required
by Paragraph 2.7(A)(2) of these Bylaws shall be delivered to the Secretary at
the principal executive offices of the Company not earlier than the 90th day
prior to such special meeting and not later than the close of business on the
later of the 70th day prior to such special meeting or the 10th day following
the day on which public announcement is first made of the date of the special
meeting and of the nominees proposed by the Board of Directors to be elected at
such meeting.

          C.  General.
              -------

              (1)   Only persons who are nominated in accordance with the
procedures set forth in these Bylaws shall be eligible to serve as directors and
only such business shall be conducted at a meeting of stockholders as shall have
been brought before the meeting in accordance with the procedures set forth in
these Bylaws. Except as otherwise provided by law, the Certificate of
Incorporation or these Bylaws, the chairman of the meeting shall have the power
and duty to determine whether a nomination or any business proposed to be
brought before the meeting was made or proposed in accordance with the
procedures set forth in these Bylaws and, if any proposed nomination or business
is not in compliance with these Bylaws, to declare that such defective proposal
or nomination shall be disregarded.

              (2)   For purposes of these Bylaws, "public announcement" shall
mean disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable national news service or in a document publicly
filed by the Company with the Securities and Exchange Commission pursuant to
Sections 13, 14 or 15(d) of the Exchange Act.

              (3)   Notwithstanding the foregoing provisions of these Bylaws, a
stockholder shall also comply with all applicable requirements of the Exchange
Act and the rules and regulations thereunder with respect to the matters set
forth in these Bylaws.  Nothing in these Bylaws shall be deemed to affect any
rights of stockholders to request inclusion of proposals in the Company's proxy
statement pursuant to Rule 14a-8 under the Exchange Act.

     2.8  Procedure for Election of Directors.  Election of directors at all
          -----------------------------------
meetings of the stockholders at which directors are to be elected may be by
written ballot, and, subject to the rights of the holders of any series of
Preferred Stock to elect additional directors under specific circumstances,
directors shall be elected by a plurality of the votes cast at such meetings.
Except as otherwise provided by law, the Certificate of Incorporation or these
Bylaws, all matters other than the election of directors submitted to the
stockholders at any meeting shall be decided by a majority of the votes cast
with respect thereto.

     2.9  Inspectors of Elections; Opening and Closing the Polls.
          ------------------------------------------------------

          A.  The Board of Directors by resolution shall appoint one or more
inspectors, which inspector or inspectors may include individuals who serve the
Company in other capacities, including, without limitation, as officers,
employees, agents or representatives of the Company, to act at a meeting of
stockholders and make a written report thereof.  One or more persons may be
designated as alternate inspectors to replace any inspector who fails to act.
If no inspector or alternate has been appointed to act, or if all inspectors or
alternates who have been appointed are unable to act at a meeting of
stockholders, the chairman of the meeting shall appoint one or more inspectors
to act at the meeting.  Each inspector, before discharging his duties, shall
take and sign an oath faithfully to execute the duties of inspector with strict
impartiality and according to the best of his ability.  The inspectors shall
have the duties prescribed by the Delaware General Corporation Law (the "DGCL").

          B.  The secretary of the meeting shall fix and announce at the meeting
the date and time of the opening and the closing of the polls for each matter
upon which the stockholders will vote at a meeting.

    2.10  Stockholder Action by Written Consent.  Any action required to be
          -------------------------------------
taken at any annual or special meeting of stockholders, or any action which may
be taken at any such meeting, may be taken without a meeting, without prior
notice and without a vote, if a consent or consents in writing, setting forth
the action so taken, shall be signed by the holders of outstanding stock having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted.

powers of the Company and do all such lawful acts and things as are not by law
or by the Certificate of Incorporation or by these Bylaws required to be
exercised or done by the stockholders.

     3.2  Number, Tenure and Qualifications.  Subject to the rights of the
          ---------------------------------
holders of any series of Preferred Stock to elect directors under specific
circumstances, the number of directors shall be fixed by, and may be increased
from time to time by, the affirmative vote of a majority of the members at any
time constituting the Board of Directors.  Each director shall hold office for
the full term for which such director is elected and until his successor shall
have been duly elected and qualified or until his earlier death, resignation or
removal in accordance with the Certificate of Incorporation or these Bylaws.
Directors need not be residents of the State of Delaware or stockholders of the
Company.

     3.3  Place of Meeting; Order of Business.  Except as otherwise provided by
          -----------------------------------
law, meetings of the Board of Directors, regular or special, may be held either
within or without the State of Delaware, at whatever place is specified by the
person or persons calling the meeting.  In the absence of specific designation,
the meetings shall be held at the principal office of the Company.  At all
meetings of the Board of Directors, business shall be transacted in such order
as shall from time to time be determined by the Chairman of the Board, or in his
absence by the President, or by resolution of the Board of Directors.

     3.4  Regular Meetings.  A regular meeting of the Board of Directors may be
          ----------------
held without other notice than these Bylaws immediately after, and at the same
place as, each annual meeting of stockholders.  The Board of Directors may, by
resolution, provide the time and place, and charges thereof, for the holding of
additional regular meetings without other notice than such resolution.

     3.5  Special Meetings.  Special meetings of the Board of Directors shall be
          ----------------

or a majority of the Board of Directors.  The person or persons authorized to

the meetings.

     3.6  Notice of Special Meetings.  Notice of any special meeting shall be
          --------------------------
given to each director at such director's business or residence in writing or by
telegram or by telephone communication.  If mailed, such notice shall be deemed
adequately delivered when deposited in the United States mail so addressed, with
postage thereon prepaid, at least five days before such meeting.  If by
telegram, such notice shall be deemed adequately delivered when the telegram is
delivered to the telegraph company at least 24 hours before such meeting.  If by
facsimile transmission, such notice shall be transmitted at least 24 hours

held at any time without notice if all the directors are present or if those not
present waive notice of the meeting in writing, either before or after such
meeting.

     3.7  Quorum.  A majority of the Board of Directors shall constitute a
          ------
quorum for the transaction of business, but if at any meeting of the Board of
Directors there shall be less than a quorum present, a majority of the directors
present may adjourn the meeting from time to time without further notice.  The
act of the majority of the directors present at a meeting at which a quorum is
present shall be the act of the Board of Directors.  The directors present at a
duly organized meeting may continue to transact business until adjournment,
notwithstanding the withdrawal of enough directors to leave less than a quorum.

     3.8  Vacancies.  Subject to the rights of the holders of any series of
          ---------
Preferred Stock to elect additional directors under specific circumstances, and
except as provided in the Certificate of Incorporation, vacancies resulting from
death, resignation or removal, and newly created directorships resulting from
any increase in the authorized number of directors, shall be filled by the
affirmative vote of a majority of the remaining directors then in office, though
less than a quorum of the Board of Directors, and directors so chosen shall hold
office for the remainder of the full term of the class of directors in which the
vacancy occurred or the new directorship was created and until such director's
successor

                                      A-15
<PAGE>

shall have been duly elected and qualified or until his earlier death,
resignation or removal. No decrease in the number of authorized directors shall
shorten the term of any incumbent director.

     3.9  Executive and Other Committees.  The Board of Directors may, by
          ------------------------------
resolution adopted by a majority of the whole Board, designate an Executive
Committee, and one or more additional committees, to exercise, subject to
applicable provisions of law, such powers of the Board in the management of the
business and affairs of the Company as set forth in said resolution, but no such
committee shall have the power or authority in reference to the following
matters: (i) approving or adopting, or recommending to the stockholders, any
action or matter expressly required to be submitted to the stockholders for
approval or (ii) adopting, amending or repealing any Bylaw of the Company.  The
Executive Committee and each such other committee shall consist of two or more
directors of the Company.  The Board of Directors may designate one or more
directors as alternate members of any committee, who may replace any absent or
disqualified member at any meeting of the committee.  Any such committee may to
the extent permitted by law exercise such powers and shall have such
responsibilities as shall be specified in the designating resolution.  In the
absence or disqualification of any member of such committee or committees, the
member or members thereof present at any meeting and not disqualified from
voting, whether or not constituting a quorum, may unanimously appoint another
member of the Board of Directors to act at the meeting in the place of any such
absent or disqualified member.  Each committee shall keep written minutes of its
proceedings and shall report such proceedings to the Board of Directors when
required.

     A majority of any committee may determine its action and fix the time and
place of its meetings, unless the Board of Directors shall otherwise provide.

manner provided for in Paragraph 3.6 of these Bylaws.  The Board of Directors
shall have power at any time to fill vacancies in, to change the membership of,
or to dissolve any such committee.  Nothing herein shall be deemed to prevent
the Board of Directors from appointing one or more committees consisting in
whole or in part of persons who are not directors of the Company; provided,
however, that no such committee shall have or may exercise any authority of the
Board of Directors.

     3.10 Action Without a Meeting.  Unless otherwise restricted by the
          ------------------------
Certificate of Incorporation or these Bylaws, any action required or permitted
to be taken at a meeting of the Board of Directors, or any committee thereof,

committee, as the case may be, and filed with the Secretary.

Board of Directors, or members of any committee designated by the Board of
Directors, may participate in and hold a meeting by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and participation in a meeting
pursuant to this Paragraph 3.11 shall constitute presence in person at such
meeting, except where a person participates in the meeting for the express
purpose of objecting to the transaction of any business on the ground that the
meeting is not lawfully called or convened.

     3.12 Removal.  Subject to the rights of the holders of any series of
          -------

          A.   The interest of each stockholder of the Company shall be
evidenced by certificates for shares of stock in such form as the appropriate
officers of the Company may from time to time prescribe, unless it shall be
determined by, or pursuant to, a resolution adopted by the Board of Directors
that the shares representing such interest be uncertificated. The shares of the
stock of the Company shall be transferred on the books of the Company by the
holder thereof in person or by such person's attorney, upon surrender for
cancellation of certificates for the same number of shares, with an assignment
and power of transfer endorsed thereon or attached thereto, duly executed, with
such proof of the authenticity of the signature as the Company or its agents may
reasonably require.

          B.   The certificates of stock shall be signed, countersigned and
registered in such manner as the Board of Directors may by resolution prescribe,
which resolution may permit all or any of the signatures on such certificates to
be in facsimile.  In case any officer, transfer agent or registrar who has

ceased to be such officer, transfer agent or registrar before such certificate
is issued, it may be issued by the Company with the same effect as if he were
such officer, transfer agent or registrar at the date of issue.

                                Indemnification

     6.1  Mandatory Indemnification.  Each person who was or is made a party or
          -------------------------
is threatened to be made a party, or who was or is a witness without being named
a party, to any threatened, pending or completed action, claim, suit or
proceeding, whether civil, criminal, administrative or investigative, any appeal
in such an action, suit or proceeding, and any inquiry or investigation that
could lead to such an action, suit or proceeding (a "Proceeding"), by reason of
the fact that such individual is or was a director or officer of the Company, or
while a director or officer of the Company is or was serving at the request of
the Company as a director, officer, partner, venturer, proprietor, trustee,
employee, agent or similar functionary of another corporation, partnership,
trust, employee benefit plan or other enterprise, shall be indemnified and held
harmless by the Company from and against any judgments, penalties (including
excise taxes), fines, amounts paid in settlement and reasonable expenses
(including court costs and attorneys' fees) actually incurred by such person in
connection with such Proceeding if it is determined that he acted in good faith
and reasonably believed (A) in the case of conduct in his official capacity on
behalf of the Company that his conduct was in the Company's best interests, (B)
in all other cases, that his conduct was not opposed to the best interests of
the Company, and (C) with respect to any Proceeding which is a criminal action,
that he had no reasonable cause to believe his conduct was unlawful; provided,
however, that in the event a determination is made that such person is liable to
the Company or is found liable on the basis that personal benefit was improperly
received by such person, the indemnification is limited to reasonable expenses
actually incurred by such person in connection with the Proceeding and shall not
be made in respect of any Proceeding in which such person shall have been found
liable for willful or intentional misconduct in the performance of his duty to
the Company.  The termination of any Proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself be determinative of whether the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Company, and, with respect to any Proceeding which is a
criminal action, had no reasonable cause to believe that his conduct was
unlawful.  A person shall be deemed to have been found liable in respect of any
claim, issue or matter only after the person shall have been so adjudged by a
court of competent jurisdiction after exhaustion of all appeals therefrom.

     6.2  Determination of Indemnification.  Any indemnification under the
          --------------------------------
foregoing Paragraph 6.1 (unless ordered by a court of competent jurisdiction)
shall be made by the Company only upon a determination that indemnification of
such person is proper in the circumstances by virtue of the fact that it shall
have been determined that such person has met the applicable standard of
conduct.  Such determination shall be made (A) by a majority vote of a quorum
consisting of directors who at the time of the vote are not named defendants or
respondents in the Proceeding; (B) if such quorum cannot be obtained, by a
majority vote of a committee of the Board of Directors, designated to act in the
matter by a majority of all directors, consisting solely of two or more
directors who at the time of the vote are not named defendants or respondents in
the Proceeding; (C) by special legal counsel (in a written opinion) selected by
the Board of Directors or a committee of the Board of Directors by a vote as set
forth in clause (A) or (B) of this Paragraph

                                      A-18
<PAGE>

6.2, or, if such quorum cannot be obtained and such committee cannot be
established, by a majority vote of all directors (in which directors who are
named defendants or respondents in the Proceeding may participate); or (D) by
the stockholders of the Company in a vote that excludes the shares held by
directors who are named defendants or respondents in the Proceeding.

     6.3  Advance of Expenses.  Reasonable expenses, including court costs and
          -------------------
attorneys' fees, incurred by a person who was or is a witness or who was or is
named as a defendant or respondent in a Proceeding, by reason of the fact that
such individual is or was a director or officer of the Company, or while a
director or officer of the Company is or was serving at the request of the
Company as a director, officer, partner, venturer, proprietor, trustee,
employee, agent, or similar functionary of another corporation, partnership,
trust, employee benefit plan or other enterprise, shall be paid by the Company
at reasonable intervals in advance of the final disposition of such Proceeding,
and without the determination specified in the foregoing Paragraph 6.2, upon
receipt by the Company of a written affirmation by such person of his good faith
belief that he has met the standard of conduct necessary for indemnification
under this Article 6, and a written undertaking by or on behalf of such person
to repay the amount paid or reimbursed by the Company if it is ultimately
determined that he is not entitled to be indemnified by the Company as
authorized in this Article 6.  Such written undertaking shall be an unlimited
obligation of such person and it may be accepted without reference to financial
ability to make repayment.

     6.4  Permissive Indemnification.  The Board of Directors of the Company may
          --------------------------
authorize the Company to indemnify employees or agents of the Company, and to
advance the reasonable expenses of such persons, to the same extent, following
the same determinations and upon the same conditions as are required for the
indemnification of and advancement of expenses to directors and officers of the
Company.

     6.5  Nature of Indemnification.  The indemnification and advancement of
          -------------------------
expenses provided hereunder shall not be deemed exclusive of any other rights to
which those seeking indemnification may be entitled under the Certificate of
Incorporation, these Bylaws, any agreement, vote of stockholders or
disinterested directors or otherwise, both as to actions taken in an official
capacity and as to actions taken in any other capacity while holding such
office, shall continue as to a person who has ceased to be a director, officer,
employee or agent of the Company and shall inure to the benefit of the heirs,
executors and administrators of such person.

     6.6  Insurance.  The Company shall have the power and authority to purchase
          ---------
and maintain insurance or another arrangement on behalf of any person who is or
was a director, officer, employee or agent of the Company, or who is or was
serving at the request of the Company as a director, officer, partner, venturer,
proprietor, trustee, employee, agent, or similar functionary of another foreign
or domestic corporation, partnership, joint venture, sole proprietorship, trust,
employee benefit plan or other enterprise against any liability, claim, damage,
loss or risk asserted against such person and incurred by such person in any
such capacity or arising out of the status of such person as such, irrespective
of whether the Company would have the power to indemnify and hold such person
harmless against such liability under the provisions hereof.  If the insurance
or other arrangement is with a person or entity that is not regularly engaged in
the business of providing insurance coverage, the insurance or arrangement may
provide for payment of a liability with respect to which the Company would not
have the power to indemnify the person only if including coverage for the
additional liability has been approved by the stockholders of the Company.
Without limiting the power of the Company to procure or maintain any kind of
insurance or other arrangement, the Company may, for the benefit of persons
indemnified by the Company, (A) create a trust fund; (B) establish any form of
self-insurance; (C) secure its indemnity obligation by grant of a security
interest or other lien on the assets of the Company; or (D) establish a letter
of credit, guaranty, or surety arrangement.  The insurance or other arrangement
may be procured, maintained, or established within the Company or with any
insurer or other person deemed appropriate by the Board of Directors regardless
of whether all or part of the stock or other securities of the insurer or other
person are owned in whole or part by the Company.  In the absence of fraud, the
judgment of the Board of Directors as to the terms and conditions of the
insurance or other arrangement and the identity of the insurer or other person
participating in the arrangement shall be conclusive and the insurance or
arrangement shall not be voidable and shall not subject the directors approving
the insurance or arrangement to liability, on any ground, regardless of whether
directors participating in the approval are beneficiaries of the insurance or
arrangement.

     6.7  Notice.  Any indemnification or advance of expenses to a present or
          ------
former director of the Company in accordance with this Article 6 shall be
reported in writing to the stockholders of the Company with or before the notice
or waiver of notice of the next stockholders' meeting or with or before the next
submission of a consent to action without a meeting and, in any case, within the
next twelve month period immediately following the indemnification or advance.

                                      A-19

     6.8  Change of Control.  Following any "change of control" of the Company
          ----------------
of the type required to be reported under Item 1 of Form 8-K promulgated under
the Exchange Act, any determination as to entitlement to indemnification shall
be made by independent legal counsel selected by the claimant which independent
legal counsel shall be retained by the Board of Directors on behalf of the
Company.

     6.9  Amendment.  Any amendment or repeal of this Article VI shall not
          ---------
adversely affect any right or protection existing hereunder in respect of any
act or omission occurring prior to such amendment or repeal.

                                  ARTICLE VII
                           Miscellaneous Provisions

     7.3  Seal.  The corporate seal may bear in the center the emblem of some
          ----
object, and shall have inscribed thereunder the words "Corporate Seal" and

     7.4  Waiver of Notice.  Whenever any notice is required to be given to any
          ----------------
stockholder or director of the Company under the provisions of the DGCL, a
waiver thereof in writing, signed by the person or persons entitled to such
notice, whether before or after the time stated therein, shall be deemed
equivalent to the giving of such notice.  Neither the business to be transacted
at, nor the purpose of, any annual or special meeting of the stockholders or of
the Board of Directors need be specified in any waiver of notice of such
meeting.

     7.5  Audits.  The accounts, books and records of the Company shall be
          ------
audited upon the conclusion of each fiscal year by an independent certified
public accountant selected by the Board of Directors, and it shall be the duty
of the Board of Directors to cause such audit to be made annually.

     7.6  Resignations.  Any director or any officer, whether elected or
          ------------
appointed, may resign at any time by serving written notice of such resignation
on the Chairman of the Board, the Chief Executive Officer, the President, if
any, or the Secretary, and such resignation shall be deemed to be effective as
of the close of business on the date said notice is received by the Chairman of
the Board, the Chief Executive Officer, the President, if any, or the Secretary
or at such later date as is stated therein.  No formal action shall be required
of the Board of Directors or the stockholders to make any such resignation
effective.

a majority of the Company's stock, outstanding and entitled to vote at the
meeting at which any Bylaw is adopted, amended or repealed.

     Adopted April 2, 2001.

Actions

A.   Any shareholder of a domestic corporation shall have the right to dissent
from any of the following corporate actions:

     (1)  Any plan of merger to which the corporation is a party if shareholder
approval is required by Article 5.03 or 5.16 of this Act and the shareholder
holds shares of a class or series that was entitled to vote thereon as a class
or otherwise;

     (2)  Any sale, lease, exchange or other disposition (not including any
pledge, mortgage, deed of trust or trust indenture unless otherwise provided in
the articles of incorporation) of all, or substantially all, the property and
assets, with or without good will, of a corporation if special authorization of
the shareholders is required by this Act and the shareholders hold shares of a
class or series that was entitled to vote thereon as a class or otherwise;

     (3)  Any plan of exchange pursuant to Article 5.02 of this Act in which the
shares of the corporation of the class or series held by the shareholder are to
be acquired.

B.   Notwithstanding the provisions of Section A of this Article, a shareholder
shall not have the right to dissent from any plan of merger in which there is a
single surviving or new domestic or foreign corporation, or from any plan of
exchange, if:

     (1)  the shares held by the shareholder are part of a class or series,
shares of which are on the record date fixed to determine the shareholders
entitled to vote on the plan of merger or plan of exchange:

Art. 5.12.  Procedure for Dissent by Shareholders as to Said Corporate Actions

A.   Any shareholder of any domestic corporation who has the right to dissent
from any of the corporate actions referred to in Article 5.11 of this Act may
exercise that right to dissent only by complying with the following procedures:

     (1)  (a)  With respect to proposed corporate action that is submitted to a
vote of shareholders at a meeting, the shareholder shall file with the
corporation, prior to the meeting, a written objection to the action, setting
out that the shareholder's right to dissent will be exercised if the action is
effective and giving the shareholder's address, to which notice thereof shall be
delivered or mailed in that event. If the action is effected and the shareholder
shall not have voted in favor of the action, the corporation, in the case of
action other than a merger, or the surviving or new corporation (foreign or
domestic) or other entity that is liable to discharge the shareholder's right of
dissent, in the case of a merger, shall, within ten (10) days after the action
is effected, deliver or mail to the shareholder written notice that the action
has been effected, and the shareholder may, within ten (10) days from the
delivery or mailing of the notice, make written demand on the existing,
surviving, or new corporation (foreign or domestic) or other entity, as the case
may be, for payment of the fair value of the shareholder's shares. The fair
value of the shares shall be the value thereof as of the day immediately
preceding the meeting, excluding any appreciation or depreciation in
anticipation of the proposed action. The demand shall state the number and class
of the shares owned by the shareholder and the fair value of the shares as
estimated by the shareholder. Any shareholder failing to make demand within the
ten (10) day period shall be bound by the action.

          (b)  With respect to proposed corporate action that is approved
pursuant to Section A of Article 9.10 of this Act, the corporation, in the case
of action other than a merger, and the surviving or new corporation (foreign or
domestic) or other entity that is liable to discharge the shareholder's right of
dissent, in the case of a merger, shall, within ten (10) days after the date the
action is effected, mail to each shareholder of record as of the effective date
of the action notice of the fact and date of the action and that the shareholder
may exercise the shareholder's right to dissent from the action. The notice
shall be accompanied by a copy of this Article and any articles or documents
filed by the corporation with the Secretary of State to effect the action. If
the shareholder shall not have consented to the taking of the action, the
shareholder may, within twenty (20) days after the mailing of the notice, make
written demand on the existing, surviving, or new corporation (foreign or
domestic) or other entity, as the case may be, for payment of the fair value of
the shareholder's shares. The fair value of the shares shall be the value
thereof as of the date the written consent authorizing the action was delivered
to the corporation pursuant to Section A of Article 9.10 of this Act, excluding
any appreciation or depreciation in anticipation of the action. The demand shall
state the number and class of shares owned by the dissenting shareholder and the
fair value of the shares as estimated by the shareholder. Any shareholder
failing to make demand within the twenty (20) day period shall be bound by the
action.

     (2)  Within twenty (20) days after receipt by the existing, surviving, or
new corporation (foreign or domestic) or other entity, as the case may be, of a
demand for payment made by a dissenting shareholder in accordance with
Subsection (1) of this Section, the corporation (foreign or domestic) or other
entity shall deliver or mail to the shareholder a written notice that shall
either set out that the corporation (foreign or domestic) or other entity
accepts the amount claimed in the demand and agrees to pay that amount within
ninety (90) days after the date on which the action was effected, and, in the
case of shares represented by certificates, upon the surrender of the
certificates duly endorsed, or shall contain an estimate by the corporation
(foreign or domestic) or other entity of the fair value of the shares, together
with an offer to pay the amount of that estimate within ninety (90) days after
the date on which the action was effected, upon receipt of notice within sixty
(60) days after that date from the shareholder that the shareholder agrees to
accept that amount and, in the case of shares represented by certificates, upon
the surrender of the certificates duly endorsed.

     (3)  If, within sixty (60) days after the date on which the corporate
action was effected, the value of the shares is agreed upon between the
shareholder and the existing, surviving, or new corporation (foreign or
domestic) or other entity, as the case may be, payment for the shares shall be
made within ninety (90) days after the date on which the action was effected
and, in the case of shares represented by certificates, upon surrender of the
certificates

                                      B-2
<PAGE>

duly endorsed. Upon payment of the agreed value, the shareholder shall cease to
have any interest in the shares or in the corporation.

B.   If, within the period of sixty (60) days after the date on which the
corporate action was effected, the shareholder and the existing, surviving, or
new corporation (foreign or domestic) or other entity, as the case may be, do
not so agree, then the shareholder or the corporation (foreign or domestic) or
other entity may, within sixty (60) days after the expiration of the sixty (60)
day period, file a petition in any court of competent jurisdiction in the county
in which the principal office of the domestic corporation is located ` asking
for a finding and determination of the fair value of the shareholder's shares.
Upon the filing of any such petition by the shareholder, service of a copy
thereof shall be made upon the corporation (foreign or domestic) or other
entity, which shall, within ten (10) days after service, file in the office of
the clerk of the court in which the petition was filed a list containing the
names and addresses of all shareholders of the domestic corporation who have
demanded payment for their shares and with whom agreements as to the value of
their shares have not been reached by the corporation (foreign or domestic) or
other entity. If the petition shall be filed by the corporation (foreign or
domestic) or other entity, the petition shall be accompanied by such a list. The
clerk of the court shall give notice of the time and place fixed for the hearing
of the petition by registered mail to the corporation (foreign or domestic) or
other entity and to the shareholders named on the list at the addresses therein
stated. The forms of the notices by mail shall be approved by the court. All
shareholders thus notified and the corporation (foreign or domestic) or other
entity shall thereafter be bound by the final judgment of the court.

C.   After the hearing of the petition, the court shall determine the
shareholders who have complied with the provisions of this Article and have
become entitled to the valuation of and payment for their shares, and shall
appoint one or more qualified appraisers to determine that value.  The
appraisers shall have power to examine any of the books and records of the
corporation the shares of which they are charged with the duty of valuing, and
they shall make a determination of the fair value of the shares upon such
investigation.  The appraisers shall also afford a reasonable opportunity to the
parties interested to submit to them pertinent evidence as to the value of the
shares. The appraisers shall also have such power and authority as may be
conferred on Masters in Chancery by the Rules of Civil Procedure or by the order
of their appointment.

D.   The appraisers shall determine the fair value of the shares of the
shareholders adjudged by the court to be entitled to payment for their shares
and shall file their report of that value in the office of the clerk of the
court. Notice of the filing of the report shall be given by the clerk to the
parties in interest. The report shall be subject to exceptions to be heard
before the court both upon the law and the facts. The court shall by its
judgment determine the fair value of the shares of the shareholders entitled to
payment for their shares and shall direct the payment of that value by the
existing, surviving, or new corporation (foreign or domestic) or other entity,
together with interest thereon, beginning 91 days after the date on which the
applicable corporate action from which the shareholder elected to dissent was
effected to the date of such judgment, to the shareholders entitled to payment
The judgment shall be payable to the holders of uncertificated shares
immediately but to the holders of shares represented by certificates only upon,
and simultaneously with, the surrender to the existing, surviving, or new
corporation (foreign or domestic) or other entity, as the case may be, of duly
endorsed certificates for those shares. Upon payment of the judgment, the
dissenting shareholders shall cease to have any interest in those shares or in
the corporation.  The court shall allow the appraisers a reasonable fee as court
costs, and all court costs shall be allotted between the parties in the manner
that the court determines to be fair and equitable.

E.   Shares acquired by the existing, surviving, or new corporation (foreign or
domestic) or other entity, as the case may be, pursuant to the payment of the
agreed value of the shares or pursuant to payment of the judgment entered for
the value of the shares, as in this Article provided, shall, in the case of a
merger, be treated as provided in the plan of merger and, in all other cases,
may be held and disposed of by the corporation as in the case of other treasury
shares.

F.   The provisions of this Article shall not apply to a merger if, on the date
of the filing of the articles of merger, the surviving corporation is the owner
of all the outstanding shares of the other corporations, domestic or foreign,
that are parties to the merger.

G.   In the absence of fraud in the transaction, the remedy provided by this
Article to a shareholder objecting to any corporate action referred to in
Article 5.11 of this Act is the exclusive remedy for the recovery of the value
of his shares or money damages to the shareholder with respect to the action. If
the existing, surviving, or new

                                      B-3
<PAGE>

corporation (foreign or domestic) or other entity, as the case may be, complies
with the requirements of this Article, any shareholder who fails to comply with
the requirements of this Article shall not be entitled to bring suit for the
recovery of the value of his shares or money damages to the shareholder with
respect to the action.

Art. 5.13.  Provisions Affecting Remedies of Dissenting Shareholders

A.   Any shareholder who has demanded payment for his shares in accordance with
either Article 5.12 or 5.16 of this Act shall not thereafter be entitled to vote
or exercise any other rights of a shareholder except the right to receive
payment for his shares pursuant to the provisions of those articles and the
right to maintain an appropriate action to obtain relief on the ground that the
corporate action would be or was fraudulent, and the respective shares for which
payment has been demanded shall not thereafter be considered outstanding for the
purposes of any subsequent vote of shareholders.

B.   Upon receiving a demand for payment from any dissenting shareholder, the
corporation shall make an appropriate notation thereof in its shareholder
records. Within twenty (20) days after demanding payment for his shares in
accordance with either Article 5.12 or 5.16 of this Act, each holder of
certificates representing shares so demanding payment shall submit such
certificates to the corporation for notation thereon that such demand has been
made. The failure of holders of certificated shares to do so shall, at the
option of the corporation, terminate such shareholder's rights under Articles
5.12 and 5.16 of this Act unless a court of competent jurisdiction for good and
sufficient cause shown shall otherwise direct. If uncertificated shares for
which payment has been demanded or shares represented by a certificate on which
notation has been so made shall be transferred, any new certificate issued
therefor shall bear similar notation together with the name of the original
dissenting holder of such shares and a transferee of such shares shall acquire
by such transfer no rights in the corporation other than those which the
original dissenting shareholder had after making demand for payment of the fair
value thereof.

C.   Any shareholder who has demanded payment for his shares in accordance with
either Article 5.12 or 5.16 of this Act may withdraw such demand at any time
before payment for his shares or before any petition has been filed pursuant to
Article 5.12 or 5.16 of this Act asking for a finding and determination of the
fair value of such shares, but no such demand may be withdrawn after such
payment has been made or, unless the corporation shall consent thereto, after
any such petition has been filed. If, however, such demand shall be withdrawn as
hereinbefore provided, or if pursuant to Section B of this Article the
corporation shall terminate the shareholder's rights under Article 5.12 or 5.16
of this Act, as the case may be, or if no petition asking for a finding and
determination of fair value of such shares by a court shall have been filed
within the time provided in Article 5.12 or 5.16 of this Act, as the case may
be, or if after the hearing of a petition filed pursuant to Article 5.12 or
5.16, the court shall determine that such shareholder is not entitled to the
relief provided by those articles, then, in any such case, such shareholder and
all persons claiming under him shall be conclusively presumed to have approved
and ratified the corporate action from which he dissented and shall be bound
thereby, the right of such shareholder to be paid the fair value of his shares
shall cease, and his status as a shareholder shall be restored without prejudice
to any corporate proceedings which may have been taken during the interim, and
such shareholder shall be entitled to receive any dividends or other
distributions made to shareholders in the interim.

                                    Part II

                    INFORMATION NOT REQUIRED IN PROSPECTUS
                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

     As permitted by the DGCL, our certificate of incorporation includes,
subject to the limitations described below, a provision that would limit or
eliminate our directors' liability for monetary damages for breaches of their
fiduciary duties. A director's liability cannot be limited or eliminated for:

     .  breaches of the duty of loyalty;

     .  acts or omissions not in good faith or that involve intentional
        misconduct or a knowing violation of law;

     .  the payment of unlawful dividends or expenditure of funds for unlawful
        stock purchases or redemptions; or

     .  transactions from which the director derived an improper personal
        benefit.

     In addition, the limitation of liability provisions may not restrict a
director's liability for violation of, or otherwise relieve the corporation or
its directors from, the necessity of complying with federal or state securities
laws or affect the availability of nonmonetary remedies such as injunctive
relief or rescission.

     Our certificate of incorporation provides that we shall, to the extent
legally permissible, indemnify each of our former or present directors or
officers against all liabilities and expenses imposed upon or incurred by any of
them in connection with, or arising out of, the defense or disposition of any
action, suit or other proceeding, civil or criminal, in which he may be
threatened or involved, by reason of his having been a director or officer, if
it is determined that he acted in good faith and reasonably believed:

     .  in the case of conduct in his official capacity on our behalf that his
        conduct was in our best interests;

     .  in all other cases, that his conduct was not opposed to our best
        interests; and

     .  with respect to any proceeding which is a criminal action, that he had
        no reasonable cause to believe his conduct was unlawful.

     The termination of any proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself be determinative of whether the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to our best
interests, and, with respect to any proceeding which is a criminal action, had
no reasonable cause to believe that his conduct was unlawful.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling Houston American
pursuant to the foregoing provisions, or otherwise, we are aware that, in the
opinion of the SEC, such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable

The undersigned Registrant hereby undertakes:

              (1)   To file, during any period in which it offers or sells
              securities, a post-effective amendment to this registration
              statement to:

               (i)   Include any prospectus required by section 10(a)(3) of the
               Securities Act;

               (ii)  Reflect in the prospectus any facts or events which,
               individually or together, represent a fundamental change in the
               information in the registration statement.  Notwithstanding the
               foregoing, any increase or decrease in volume of securities
               offered (if the total dollar value of securities offered would
               not exceed that which was registered) and any deviation from the
               low or high end of the estimated maximum offering range may be
               reflected in the form of prospectus filed with the Commission
               pursuant to Rule 424(b) if, in the aggregate, the changes in
               volume and price represent no more than a 20% change in the
               maximum aggregate offering price set forth in the "Calculation of

          (2)  For determining liability under the Securities Act, treat each
          post-effective amendment as a new registration statement of the
          securities offered, and the offering of the securities at that time to
          be the initial bona fide offering.

          (3)  File a post-effective amendment to remove from registration any
          of the securities that remain unsold at the end of the offering.

          (4)  The undersigned registrant hereby undertakes to respond to
          requests for information that is incorporated by reference into the
          prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within
          one business day of receipt of such request, and to send the
          incorporated documents by first class mail or other equally prompt
          means. This includes information contained in documents filed
          subsequent to the effective date of the registration statement through
          the date of responding to the request.

          (5)  The undersigned registrant hereby undertakes to supply by means
          of a post-effective amendment all information concerning a
          transaction, and the company being acquired involved therein, that was
          not the subject of and included in the registration statement when it
          became effective.
