ITEM 1.   DESCRIPTION OF BUSINESS.

     Pan Western Energy Corporation (the "Company") is an independent oil and
gas company engaged in the acquisition, development and production of oil and
gas in the United States.  The Company was incorporated in 1981 under the laws
of the State of Oklahoma with the objective of exploring for, developing,
producing and managing oil and gas reserves.  Early efforts of the Company
focused on exploratory drilling in Oklahoma, Colorado, Kansas, Nebraska and
Texas.  Since 1989, the Company has focused primarily on the acquisition of
producing oil and gas properties in Oklahoma and Texas.  During 1995 and 1996,
the Company acquired the producing oil and gas properties of six limited
partnerships in which the Company was the general partner.  These producing
properties, along with producing properties acquired from others during the same
period, significantly increased the Company's asset base.

     The Company currently owns and operates producing oil and gas properties
located in the states of Texas and Oklahoma and owns royalty interests in 14
non-operated wells located in the state of Ohio.  Daily gross production from
109 wells operated by the Company in these states currently averages
approximately 234 Bbls of oil and 1,395 Mcf of gas.  Total daily production from
both operated and non-operated wells, net to the Company's interest, currently
averages approximately 175 Bbls of oil and 788 Mcf of gas from a total of 68 net
wells.

     In seeking to acquire additional oil and gas properties, the Company
focuses primarily on properties with producing oil and gas reserves which it
believes have potential for additional exploitation through additional
development and enhanced recovery via lateral completions and improved operating
techniques rather than highly speculative exploration efforts.  The Company
intends to focus its acquisition program on producing properties in which the
Company will become the operator following acquisition, allowing the Company to
maintain a low cost operating structure.  The Company will also seek properties
that are underdeveloped, overly burdened with expenses or owned by financially
troubled companies.  Management intends to focus on oil and gas properties
located in the mid-continent region of the United States where Company personnel
are best able to draw on their prior oil and gas experience.  The Company
intends to acquire properties using internally generated cash flow, bank
borrowings and, when appropriate, Common Stock of the Company.

     The Company's principal offices are located at 1850 South Boulder Avenue,
Suite 300, Tulsa, Oklahoma 74119 and its telephone number is (918) 582-4957.

CAUTIONARY STATEMENT AND RISK FACTORS

     Cautionary Statement Regarding Forward-Looking Statements.  In the interest
of providing the Company's shareholders and potential investors with certain
information regarding the Company, including management's assessment of the
Company's future plans and operations, certain statements set forth in this
Registration Statement contain or are based on the Company's projections or
estimates of revenue, income, earnings per share and other financial items or
relate to management's future plans and objectives or to the Company's future
economic and financial performance.  All such statements, other than statements
of historical fact, contained in this Registration Statement, including
statements in "Item 1. Description of Business, Item 2. Management's Discussion
and Analysis or Plan of Operation and Item 3. Description of Property" generally
are accompanied by words such as "anticipate," "believe," "intend," "estimate,"
"project" or "expect" or similar statements.  Such statements are "forward-
looking statements" within the meaning of Section 27A of the Securities Act

                                       5
<PAGE>
 
of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as
amended, and are made pursuant to and in reliance on the safe harbor provisions
of such sections.

     Although any forward-looking statements contained in this Registration
Statement or otherwise expressed by or on behalf of the Company are, to the
knowledge and in the judgment of the officers and directors of the Company,
reasonable and expected to prove true, management is not able to predict the
future with certainty and no assurance can be given that such statements will
prove correct.  Forward-looking statements involve known and unknown risks and
uncertainties which may cause the Company's actual performance and financial
results in future periods to differ materially from any projection, estimate or
forecasted result.  These risks and uncertainties include, among other things:
general economic and business conditions; oil and gas industry conditions and
trends; volatility of oil and gas prices; product supply and demand; market
competition; risks inherent in the Company's oil and gas operations; imprecision
of reserve estimates; the Company's ability to replace and expand oil and gas
reserves; the Company's ability to generate sufficient cash flow from operations
to meet its current and future obligations; the Company's ability to access and
terms of external sources of debt and equity capital; and such other risks and
uncertainties described from time to time in the Company's periodic reports and
filings with the Securities and Exchange Commission.  These and other risks are
described elsewhere in this Registration Statement and will be described from
time to time in the Company's future filings with the Securities and Exchange
Commission.  Accordingly, shareholders and potential investors are cautioned
that certain events or circumstances could cause actual results to differ
materially from those projected, estimated or predicted.  In addition, forward-
looking statements are based on management's knowledge and judgment as of the
date of this Registration Statement, and the Company does not intend to update
any forward-looking statements to reflect events occurring or circumstances
existing hereafter.

     History of Losses; Accumulated Deficit.  For the fiscal years ended
December 31, 1996 and 1995, the Company incurred net losses of $252,444 and
$364,092 respectively.  At December 31, 1996, the Company had an accumulated
deficit of $880,537 and its working capital deficit was $1,361,893.  It is
expected that the Company will continue to experience losses in the near term.
The Company's ability to achieve profitability and generate cash flow will be
dependent upon obtaining additional debt or equity capital and acquiring or
developing additional oil and gas properties.  There can be no assurance that
the Company will be able to do so.  See "Item 2. Management's Discussion and
Analysis or Plan of Operation" and the Company's Financial Statements included
elsewhere in this Registration Statement.

     Limited Available Capital; Need for Additional Financing.  Without raising
additional capital, the Company will be unable to acquire additional producing
oil and gas properties and its ability to develop its existing oil and gas
properties will be limited to the extent of available cash flow.  Accordingly,
in order for the Company to achieve its business objective and achieve
profitable operations, it will be necessary to generate additional cash flow
from operations, raise additional capital or enter into joint oil and gas
development arrangements.  Management intends to fund future acquisitions and
develop its oil and gas reserves using cash flow from operations as well as
borrowings, public and private sales of debt and equity securities and joint oil
and gas development arrangements, among other possible sources.  The Company has
no present arrangements for future borrowings and its cash flow from operations
is not expected to be adequate to provide the funds needed for these purposes.
There can be no assurance the Company will be able to raise additional funds in
sufficient amounts to allow the Company to successfully implement its present
business strategy of additional oil

                                       6
<PAGE>
 
and gas property acquisitions or the development of its existing oil and gas
reserves.  No assurance can be given as to the availability or terms of any
additional financing or joint development arrangements or that such terms as are
available may not be dilutive to the interests of the Company's shareholders.

     Industry Conditions; Impact on Company's Profitability.  The profitability
and revenues of the Company are dependent, to a significant extent, upon
prevailing market prices for oil and gas.  In the past, oil and gas prices and
markets have been volatile.  Prices are subject to wide fluctuations in response
to changes in supply of, and demand for, oil and gas, market uncertainty and a
variety of additional factors that are beyond the control of the Company.  Such
factors include world political conditions, weather conditions, government
regulations, the price and availability of alternative fuels and overall
economic conditions.  Crude oil and natural gas prices have increased
significantly over the past 12 months.  Any decline from current oil or gas
prices would have a material adverse effect on the Company's revenues and
operating income and might, under certain conditions, require a write-down of
the book value of the Company's oil and gas properties.

     Acquisition Strategy.  The Company must acquire producing properties or
locate and develop new oil and gas reserves to replace those being depleted by
production.  Without acquisition of producing properties or successful drilling
and exploration activities, the Company's reserves and revenues will decline as
reserves are depleted by production from existing properties.  Subject to the
availability of sufficient capital, the Company intends to acquire additional
producing oil and gas properties, although no funds are currently available to
the Company for this purpose.  Although the Company engages in discussions
regarding the acquisition of additional properties on a regular basis, as of the
date of this Registration Statement the Company has no agreements or
understandings to acquire any other properties and there can be no assurance
that the Company will be able to identify and acquire additional producing oil
and gas properties that will prove to be profitable to the Company.  The process
of integrating acquired properties into the Company's operations may result in
unforeseen difficulties and may require a disproportionate amount of
management's attention and the Company's resources.  In connection with
acquisitions, the Company could become subject to significant contingent
liabilities arising from the exploration and development activities conducted on
the acquired properties to the extent the Company assumes, or an acquired entity
becomes liable for, unknown or contingent liabilities or in the event that such
liabilities are imposed on the Company under theories of successor liability.
See "Acquisition and "Exploitation Activities" and "Production".

     Reliance on Estimates of Proved Reserves; Depletion of Reserves.  There are
numerous uncertainties inherent in estimating quantities of proved oil and gas
reserves and in projecting future rates of production and timing of development
expenditures, including many factors beyond the control of the Company.  The oil
and gas reserve data set forth in this Registration Statement represents
estimates only.  Oil and gas reserve engineering is a subjective process of
estimating underground accumulations of oil and gas that cannot be measured in
an exact manner, and estimates by other engineers might differ from those
included in this Registration Statement.  The accuracy of any reserve estimate
is a function of the quality of available data and of engineering and geological
interpretation and judgment.  This Registration Statement contains estimates of
the Company's proved oil and gas reserves and the projected future net revenue
therefrom, which have been prepared by an independent petroleum engineering
firm.  Actual future production, oil and gas prices, revenue, capital
expenditures, taxes and operating expenses may vary substantially from those
assumed in making estimates, and the Company's reserves may be subject to
material upward or downward revision.  In addition, the Company's ability to
develop its reserves will be dependent upon the timely availability of capital
for this purpose without

                                       7
<PAGE>
 
which the Company's ability to produce the projected amounts of oil and gas will
be adversely affected, thereby adversely affecting the projected future net
revenue.  See "Reserves".

     Dependence on Other Operators.  With respect to wells not operated by the
Company in which it owns an interest, the operators are, in some cases,
privately-held companies which may have limited financial resources.  If a third
party operator experiences financial difficulty and fails to pay for materials
and services in a timely manner, the wells operated by such third party
operators could be subject to material and workmen's liens.  In such event, the
Company would incur costs in discharging such liens.  The Company has no reason
to believe that its current operators are experiencing significant financial
difficulties.

     Competition.  The oil and gas industry is highly competitive.  The Company
competes with major integrated and independent oil and gas companies in
acquiring oil and gas properties.  Many competitors have resources substantially
exceeding the resources of the Company.  See "Competition".

     Acquisition and Production Risks.  The successful acquisition and
exploitation of producing oil and gas properties requires an assessment of the
recoverable reserves, future oil and gas prices, operating costs, the existence
of potential environmental and other liabilities and other factors.  Such
assessments are necessarily inexact and their accuracy is inherently uncertain.
Although the Company's management will perform a review of the assets of all
proposed acquisitions which management believes to be consistent with standard
industry practices, such reviews are inherently incomplete.  The Company intends
to focus its due diligence efforts on the properties that management believes
contain the majority of the value in a proposed acquisition and sample the
balance of included properties.  Even an in-depth review of all properties and
records of a proposed acquisition will not necessarily reveal existing or
potential problems or risks nor will it permit the Company to become
sufficiently familiar with the properties to fully assess their deficiencies,
liabilities and capabilities.  Inspections are not likely to be performed on
each and every well, and potential environmental problems are not necessarily
observable even when an inspection is undertaken.  Although the Company's
management has substantial experience in the oil and gas business, the
particular oil and gas assets that the Company may acquire may be unfamiliar.

     Operational and Environmental Hazards; Insurance.  The oil and gas industry
involves a number of operating risks, such as the risks of fire, blowouts,
explosions, cratering, pipe failure, casing collapse and abnormally pressured
formations, the occurrence of any of which could materially and adversely affect
the Company.  The business is also subject to environmental hazards including
oil and saltwater spills, gas leaks, ruptures and discharges of toxic gases.
These risks could result in substantial losses to the Company due to injury and
loss of life, severe damage to and destruction of property and equipment,
pollution and other environmental damage, and suspension of operations.  As the
owner of working interests in its oil and gas properties, the Company bears its
proportionate share of the obligations and liabilities arising out of the
exploration and development of those properties.  Generally, owners of working
interests in oil and gas properties are jointly and severally liable for all
such obligations and liabilities.  As a result, there exists a risk that the
Company could become liable for amounts in excess of its proportionate share of
such obligations and liabilities, although generally the Company would have a
right of contribution against the other working interest owners.  In accordance
with customary industry practices, the Company maintains insurance against some,
but not all, of such risks and losses.  The occurrence of such an event not
fully covered by insurance could have a material adverse effect on the financial
position and operations of the Company.  The Company does

                                       8
<PAGE>
 
not carry insurance covering environmental impairment liabilities.  The Company
can provide no assurance that the insurance it carries will be adequate to cover
any loss or exposure to liability, or that such insurance will continue to be
available on terms acceptable to the Company.  See "Operational Hazards and
Insurance".

     Government Regulation.  The Company's business is subject to extensive
federal, state and local laws and regulations relating to the exploration for,
development, production, marketing and transmission of oil and gas, as well as
environmental and safety matters.  Such laws and regulations have generally
become more stringent in recent years, often imposing greater liability on a
larger number of potentially responsible parties.  Because the requirements
imposed by such laws and regulations are frequently changed, the Company is
unable to predict the ultimate cost of compliance with such requirements.  The
states of Oklahoma and Texas have adopted revisions to its production allowable
rules under which they regulate the quantities of natural gas which producers
may produce within their respective borders.  Legislation has recently been
introduced in the United States Congress to restrict the ability of states to
regulate the production of natural gas.  It is impossible at this time to
determine the effect, if any, these developments may have on the natural gas
industry as a whole.  However, the Company does not believe these developments
will materially affect its operations.  There is no assurance that federal,
state or local laws and regulations enacted in the future will not adversely
affect the Company's ability to explore for, produce and market oil and natural
gas.  See "Regulation."

     Reliance on Key Personnel.  The Company is dependent upon the services of
Sid L. Anderson, President; Buddie E. Livingston, II, its Vice President of
Operations, and Vincent R. Kemendo, its Vice President of Finance.  The loss of
the services of any of these individuals could have a material adverse effect
upon the Company.  The Company does not maintain insurance on the lives of
Messrs. Anderson, Livingston, or Kemendo.  See "Item 5. Directors, Executive
Officers, Promoters and Control Persons."

     Authorization and Discretionary Issuance of Preferred Stock; Anti-takeover
Provisions.  The Company's Certificate of Incorporation authorizes the issuance
of Preferred Stock with such designations, rights and preferences as may be
determined from time to time by the Board of Directors.  Accordingly, the Board
of Directors is empowered, without shareholder approval, to issue Preferred
Stock with dividend, liquidation, conversion, voting or other rights which could
adversely affect the voting power or other rights of holders of the Company's
Common Stock.  In the event of issuance, the Preferred Stock could be utilized,
under certain circumstances, as a method of discouraging, delaying or preventing
a change in control of the Company, which could have the effect of discouraging
bids for the Company and thereby prevent shareholders from receiving a premium
for their shares over the then-current market prices.  Although the Company has
no present intention to issue any additional shares of its Preferred Stock,
there can be no assurance that the Company will not do so in the future.

     The Oklahoma General Corporation Act includes provisions which are intended
to encourage persons considering unsolicited tender offers or other unilateral
takeover proposals to negotiate with the Company's Directors rather than pursue
non-negotiated takeover attempts.  These existing takeover provisions may have a
significant effect on the ability of a shareholder to benefit from certain kinds
of transactions that may be opposed by the incumbent Directors.

     Qualification Requirements for Nasdaq Securities.  There is currently no
trading market for the Common Stock of the Company.  For the Company's Common
Stock to be eligible for initial

                                       9
<PAGE>
 
inclusion on Nasdaq, the Company must, among other things, maintain at least
$4,000,000 in total assets, and have at least $2,000,000 of capital and surplus.
In addition, the bid price of the Common Stock must be at least $3.00 per share,
the market value of the outstanding Common Stock must be at least $1,000,000 and
there must be at least 300 holders of the Common Stock.   The Company does not
currently meet these requirements and there can be no assurance that the
Company's Common Stock will meet the requirements for inclusion on Nasdaq in the
future.  It is currently anticipated that trading, if any, in the Common Stock
will be conducted in the over-the-counter market on the OTC Bulletin Board, a
NASD-sponsored inter-dealer quotation system, or in what are commonly referred
to as the "pink sheets."  As a result, a shareholder may find it more difficult
to dispose of, or to obtain accurate quotations as to the market value of, the
Company's Common Stock.  In addition, the Company's Common Stock is currently
subject to a Commission rule that imposes additional sales practice requirements
on broker-dealers who sell such securities to persons other than established
customers and accredited investors.  For transactions covered by this rule, the
broker-dealer must make a special suitability determination for the purchaser
and have received the purchaser's written consent to the transaction prior to
sale.  Consequently, the rule may affect the ability of broker-dealers to sell
the Company's Common Stock and the ability of shareholders to sell their shares
of Common Stock in the secondary market.  See "Part II, Item 1. Market Price and
Dividends on the Registrant's Common Equity and Other Shareholder Matters."

     Dividends Unlikely.  The Company has never declared or paid dividends on
its Common Stock and currently does not intend to pay dividends in the
foreseeable future.  The Company currently intends to follow a policy of
retaining all earnings, if any, to finance the expansion and development of its
business.  In any event, future dividend policy will depend upon the Company's
earnings, financial condition, working capital requirements, and will be at the
discretion of the Board of Directors.

BUSINESS STRATEGY

     The Company's business strategy has been and will continue to be the
acquisition of producing oil and gas properties and exploitation of those
properties to maximize production and ultimate reserve recovery.  The Company's
present business strategy is to concentrate on expanding its asset base and cash
flow primarily through emphasis on the following activities:

     .    Acquiring additional producing oil and gas properties, including
          properties with potential for developmental drilling to maintain a
          significant inventory of undeveloped prospects and to enhance the
          Company's foundation for future growth;

     .    Increasing production cash flow and asset value by developing the
          Company's proven undeveloped reserves;

     .    Building on the Company's existing base of operations by concentrating
          its development activities in its primary operating areas of Texas and
          Oklahoma;

     .    Serving as operator of its wells to ensure technical performance and
          reduce costs;

     .    Expanding its relationships with major and large independent oil and
          gas companies to access their producing as well as undeveloped
          properties, seismic data and financial

                                       10
<PAGE>
 
          resources;

     .    Managing financial risk and mitigating technical risk by:

          .    drilling in known productive trends with multi-horizon geologic
               potential;

          .    diversifying investment over a large number of wells in the
               Company's primary operating areas;

          .    developing properties that provide a balance between short and
               long reserve lives;

     .    Using, where appropriate, the horizontal drilling technology licensed
          by the Company from Amoco Corporation to enhance recovery of oil and
          gas from producing properties;

     .    Offering horizontal drilling services on a contract basis to third
          parties using the horizontal drilling technology licensed by the
          Company from Amoco Corporation; and

     .    Maintaining low general and administrative expenses and increasing
          economies of scale to reduce per unit Operating Costs and reserve
          addition costs.

ACQUISITION AND EXPLOITATION ACTIVITIES

     Acquisitions.  Historically, the Company has allocated a substantial
portion of its capital expenditures to the acquisition of producing oil and gas
properties.  During fiscal years 1996 and 1995, the Company acquired 706,949 and
1,843,970 Mcf of natural gas and 428,519 and 1,258,830 Bbls of oil for total
costs of approximately $222,000 and $2,246,000 respectively.  These acquisitions
represent a cost of $0.41 per Boe in 1996 and $1.43 per Boe in 1995.  The
Company has financed its acquisitions primarily through cash flow, bank
borrowings and issuance of Common Stock.

     To the extent that it has the capital resources to do so, the Company
intends to continue to pursue a business strategy that emphasizes reserve
additions through acquisitions.  The Company intends to focus its acquisition
program on producing properties which it believes have potential for additional
exploitation through additional development and enhanced recovery via lateral
completions and improved operating techniques.  The Company will seek properties
that are underdeveloped, overly burdened with expenses or owned by financially
troubled companies.  Management intends to focus on properties located in the
mid-continent region of the United States, primarily in the states of Texas and
Oklahoma, where Company personnel are best able to draw on their prior oil and
gas experience.  It is anticipated that a majority of the potential acquisition
opportunities will be internally generated by Company personnel, although some
opportunities may be brought to the Company by non-employee Directors or
stockholders of the Company.  The Company does not currently have any plans to
engage professional firms or consultants that specialize in acquisitions but may
do so in the future.  The Company may utilize any one or a combination of lines
of credit with banks, public and private sales of debt and equity securities,
joint oil and gas development arrangements and internally-generated cash flow to
finance its acquisition efforts.  No assurance can be given that sufficient
external or internal funds will be available to fund the Company's desired
acquisitions.

                                       11
<PAGE>
 
     The Company maintains its own land, geological, petroleum engineering and
accounting staff which participate in evaluating prospective acquisitions.  The
Company utilizes an acquisitions screening approach using applicable engineering
and geological criteria in the review and evaluation process.  This evaluation
process helps to form the basis of the purchase price for a potential
acquisition.  The Company generally considers the following in its decision-
making process:  discounted future net revenues, payout, dollars per proven
barrels of oil and/or Mcf of gas and other potential behind pipe zones or
drilling opportunities.  The Company will continue to weigh the comparative
value of various methods of reserve acquisitions and employ the method it
believes is most advantageous in any given transaction.  After the acquisition
of oil and gas properties, management generally develops a reservoir depletion
plan to maximize production rates, ultimate reserve recovery and cash flow
generation.  Such plans consider field operating procedures, workovers,
recompletions, secondary recovery implementation, additional drilling and such
other procedures as the situation dictates.

     The Company does not have a specific budget for the acquisition of oil and
gas properties since the timing and size of acquisitions are difficult to
forecast.  However, the Company is constantly reviewing acquisition
possibilities.

     Development Activities.  The Company concentrates its acquisition efforts
on proved producing properties which demonstrate a potential for significant
additional development through workovers, behind-pipe recompletions, secondary
recovery operations, the drilling of development or infill wells, and other
exploitation activities which the Company may find appropriate.  The Company has
pursued an active workover and recompletion program on the properties it has
acquired and intends to continue its workover and recompletion program in the
future as properties acquired warrant.  In connection with oil and gas property
acquisitions, properties are reviewed and evaluated by the Company with a view
toward taking the appropriate actions to maximize production.  Such actions may
include repair or replacement of equipment or more extensive efforts such as
recompletion in a different producing zone or implementation of secondary
recovery operations.  The expenditures required for the Company's workover and
recompletion program have historically been financed, and it is expected that
they will continue to be financed, by borrowings and internally generated funds.

     Exploratory drilling has been minimal to date.  The Company reviews
exploration proposals from other companies and individuals and may from time to
time participate in certain ventures where the risk-reward ratio is sufficiently
high to warrant capital outlays.  The Company does not anticipate generating
exploration projects utilizing its own staff at the present time.  Consequently,
exploratory drilling within the United States will likely only remain a small
part of the Company's business.

PRODUCTION

     The Company owns and operates producing oil and gas properties located in
the states of Texas and Oklahoma and owns royalty interests in 14 non-operated
wells located in the state of Ohio.  The Company continuously evaluates the
profitability of its oil, gas and related activities and has a policy of
divesting itself of unprofitable oil and gas properties or areas of operation
that are not consistent with its operating philosophy.

     The Company operates 109 producing wells and owns non-operated interests in
14 producing wells and units in these states. Oil and gas sales from the
Company's producing oil and gas properties

                                       12
<PAGE>
 
accounted for substantially all of the Company's revenues for the years ended
December 31, 1995 and 1996.

     The following summarizes the Company's principal areas of oil and gas
production activity.

OIL AND GAS PARTNERSHIPS

     The Company is the sole general partner in Pan Western 1986 Drilling
Program, Ltd. limited partnership ("1986 Program") and Pan Western 1987
Production Program, Ltd. limited partnership ("1987 Program"), whose purposes
are the acquisition, drilling, development, production, marketing and operation
of oil and gas properties.  As general partner, the Company is entitled to
18.57% and 15% of the current earnings or losses for the 1986 and 1987 Programs,
respectively, and is also entitled to a "back-in" interest upon payout.  For
additional information regarding these partnerships, See Note 3 to the Company's
Consolidated Financial Statements elsewhere in this Registration Statement.

HORIZONTAL DRILLING

     The Company has entered into a license agreement with Amoco Corporation for
a patented short-radius horizontal drilling and completion technology.  The
technology is designed to permit enhanced recovery of oil and gas from producing
formations which have high bottom hole pressures but low permeability.  This
technology has been used in several oil and gas fields at both foreign and
domestic locations.  The Company currently plans to use this technology to
maximize recoverable oil and gas reserves on a number of the Company's
properties and to offer the technology as a service to other oil and gas
producers.  The Company intends to offer its customers a complete package of
services needed to complete a short-radius horizontal extension without having
to rely on several different contractors as is the case with most of the other
companies offering horizontal drilling services.  The Company plans to offer
these services through its wholly-owned subsidiary, Lateral Completion
Technologies, Inc. ("LCT").  The Company will require additional capital to fund
the start-up operations of LCT.  No assurance can be given that such capital
will be available on terms satisfactory to the Company.

MARKETING

     The availability of a market for oil and gas produced or marketed by the
Company is dependent upon a number of factors beyond its control which cannot be
accurately predicted. These factors include the proximity of wells to, and the
available capacity of, natural gas pipelines, the extent of competitive domestic
production and imports of oil and gas, the availability of other sources of
energy, fluctuations in seasonal supply and demand, and governmental regulation.
In addition, there is always the possibility that new legislation may be enacted
which would impose price controls or additional taxes upon crude oil or natural
gas, or both. In the event a productive gas well is completed in an area that is
distant from existing gas pipelines, the Company may allow the well to remain
shut-in until a pipeline is extended to the well or until additional wells are
drilled to establish the existence of sufficient producing reserves to justify
the cost of extending existing pipelines to the area. It appears that the United
States is emerging from a period of oversupply of natural gas which has, and may
still, cause delays, restrictions or reductions of natural gas production and
which in the past has adversely affected gas prices. Oversupplies of natural gas
can be expected to recur from time to time and may result in depressed gas
prices and in the gas producing wells of the Company being shut-in.

     Since the early 1970's the supply and market price for crude oil has been
significantly affected by policies adopted by the member nations of OPEC.
Members of OPEC establish among themselves prices and production quotas for
petroleum products from time to time with the intent of manipulating the global
supply and price levels for crude oil.  In addition, Canada recently revised its
laws affecting the exportation of natural gas to the United States.  Mexico also
continues to fine tune its import/export policies.  The oil and gas policies of
the United States, Canada and Mexico are impacted by the Canadian/U.S. Free
Trade Agreement, the General Agreement on Tariffs and Trade, and the North
American Free Trade Agreement.  These factors are expected to increase
competition and may adversely affect the price of natural gas in certain areas
of the United States.  The Company is unable to predict the effect, if any,
which OPEC, Canadian and Mexican policies, and emerging international trade
doctrines will have on the amount of, or the prices received for, oil and
natural gas produced and sold by the Company.

     Changes in oil and natural gas prices significantly affect the revenues and
cash flow of the Company and the value of its oil and gas properties.
Significant declines in the prices of oil and natural gas could have a material
adverse effect on the business and financial condition of the Company.  The
Company is unable to predict accurately whether the price of oil and natural gas
will rise, stabilize or decline in the future.

     Substantially all of the Company's crude oil and condensate production is
sold at posted prices under short term contracts, as is customary in the
industry.  The most significant purchasers of the Company's oil and gas
production during the year ended December 31, 1996 were Conoco Oil Company, Sun
Oil Company, Total Petroleum, Inc., and Octagon Resources, Inc. which accounted
for 18%, 16%, 15% and 11% of the Company's total oil and gas revenues,
respectively.  No other purchaser of crude oil or natural gas during this period
exceeded 10% of the Company's oil and gas sales.

     The Company's gas production is sold primarily on the spot market or under
market sensitive long term agreements with a variety of purchasers, including
intrastate and interstate pipelines, their marketing affiliates, independent
marketing companies and other purchasers who have the ability to

                                       14
<PAGE>
 
move the gas under firm transportation agreements.

COMPETITION

     Competition in the acquisition of producing oil and gas properties and in
the exploration and production of oil and gas is intense.  In seeking to obtain
desirable producing properties, new leases and exploration prospects, the
Company faces competition from both major and independent oil and gas companies
as well as from numerous individuals.  Many of these competitors have financial
and other resources substantially in excess of those available to the Company.

     Increases in worldwide energy production capability and decreases in energy
consumption as a result of conservation efforts have brought about substantial
surpluses in energy supplies in recent years.  This, in turn, has resulted in
substantial competition for markets historically served by domestic natural gas
resources both with alternate sources of energy and among domestic gas
suppliers.  As a result, there have been reductions in oil and gas prices,
widespread curtailment of gas production and delays in producing and marketing
gas after it is discovered.  Changes in government regulations relating to the
production, transportation and marketing of natural gas have also resulted in
significant changes in the historical marketing patterns of the industry.
Generally, these changes have resulted in the abandonment by many pipelines of
long-term contracts for the purchase of natural gas, the development by gas
producers of their own marketing programs to take advantage of new regulations
requiring pipelines to transport gas for regulated fees, and the emergence of
various types of gas marketing companies and other aggregators of gas supplies.
As a consequence, gas prices, which were once effectively determined by
government regulation, are now largely established by market competition.
Competitors of the Company in this market include other producers, gas pipelines
and their affiliated marketing companies, independent marketers, and providers
of alternate energy supplies.

REGULATION

     The oil and gas industry is extensively regulated by federal, state and
local authorities.  Legislation affecting the oil and gas industry is under
constant review for amendment or expansion.  Numerous departments and agencies,
both federal and state, have issued rules and regulations applicable to the oil
and gas industry and its individual members, some of which carry substantial
penalties for the failure to comply.  The regulatory burden on the oil and gas
industry increases its cost of doing business and, consequently, affects its
profitability.  Inasmuch as such laws and regulations are frequently amended or
reinterpreted, the Company is unable to predict the future cost or impact of
complying with such regulations.

     Exploration and Production.  Exploration and production operations of the
Company are subject to various types of regulation at the federal, state and
local levels.  Such regulation includes requiring permits for the drilling of
wells, maintaining bonding requirements in order to drill or operate wells, and
regulating the location of wells, the method of drilling and casing wells, the
surface use and restoration of properties upon which wells are drilling and
producing, and the plugging and abandoning of wells.  The Company's operations
are also subject to various conservation matters.  These include the regulation
of the size of drilling and spacing units or proration units, the density of
wells which may be drilled, and the unitization or pooling of oil and gas
properties or interests.  In this regard, some states allow the forced pooling
or integration of tracts to facilitate exploration while other states rely on
voluntary pooling of lands and leases.  In addition, state conservation laws
establish maximum

                                       15
<PAGE>
 
rates of production from oil and gas wells, generally prohibit the venting or
flaring of gas, and impose certain requirements regarding the rate of
production.  The effect of these regulations is to limit the amounts of oil and
gas the Company can produce from its wells, and to limit the number of wells or
the locations at which the Company can drill.

     The states of Oklahoma and Texas have adopted or are considering revisions
to their production allowable rules under which they regulate the quantities of
natural gas which may be produced within their borders.  The stated rationale
behind such prorationing legislation and rulemaking is the conservation of
natural resources, prevention of waste and protection of the correlative rights
of oil and gas interest owners by limiting production to the available market.
It is impossible at this time to determine the effect, if any, these
developments may have on the natural gas industry as a whole.  The Company does
not believe the developments will materially affect its operations.

     Certain of the Company's oil and gas leases are granted by the federal
government and administered by various federal agencies.  Such leases require
compliance with detailed federal regulations and orders which regulate, among
other matters, drilling and operations on these leases and calculation of
royalty payments to the federal government.  The Mineral Lands Leasing Act of
1920 places limitations on the number of acres under federal leases that may be
owned in any one state.  While the Company does not have a substantial federal
lease acreage position in any state or in the aggregate, the Company does own
interests in federal oil and gas leases which produce amounts of oil and gas
material to the Company  The Mineral Lands Leasing Act of 1920 and related
regulations also may restrict a corporation from holding title to federal
onshore oil and gas leases if stock of such corporation is owned by citizens of
foreign countries which are not deemed reciprocal under such Act.  Reciprocity
depends, in large part, on whether the laws of the foreign jurisdiction
discriminate against a United States person's ownership of rights to minerals in
such jurisdiction.  The purchase of shares in the Company by citizens of foreign
countries who are not deemed to be reciprocal under such Act could have an
impact on the Company's ownership of federal leases.

     The Company's operations are subject to extensive federal, state and local
laws and regulations relating to the generation, storage, handling, emission,
transportation and discharge of materials into the environment.  Permits are
required for various of the Company's operations, and these permits are subject
to revocation, modification and renewal by issuing authorities.  Governmental
authorities have the power to enforce compliance with their regulations, and
violations are subject to fines, injunctions or both.  It is possible that
increasingly strict requirements will be imposed by environmental laws and
enforcement policies thereunder.  The Company is also subject to laws and
regulations concerning occupational safety and health.  It is not anticipated
that the Company will be required in the near future to expend amounts that are
material in the aggregate to the Company's overall operations by reason of
environmental or occupational safety and health laws and regulations, but
inasmuch as such laws and regulations are frequently changed, the Company is
unable to predict the ultimate cost of compliance.

     Natural Gas Sales and Transportation.  Federal legislation and regulatory
controls have historically affected the price of the gas produced by the Company
and the manner in which such production is marketed.  The transportation and
sale for resale of gas in interstate commerce are regulated pursuant to the
Natural Gas Act of 1938 (the "NGA") and the Natural Gas Policy Act of 1978 (the
"NGPA") and Federal Energy Regulatory Commission ("FERC") regulations
promulgated

                                       16
<PAGE>
 
thereunder.  Since 1978, maximum selling prices of certain categories of gas,
whether sold in interstate or intrastate commerce, have been regulated pursuant
to the NGPA.  The NGPA established various categories of gas and provided for
graduated deregulation of price controls of several categories of gas and the
deregulation of sales of certain categories of gas.  All price deregulation
contemplated under the NGPA has already taken place.

TITLE TO PROPERTIES

     As is customary in the oil and gas industry, the Company performs a minimal
title investigation before acquiring oil and gas properties, which generally
consists of obtaining a title report from legal counsel covering title to the
major properties (for example, properties comprising at least 80% by value of
the acquired properties) and due diligence reviews by independent landmen of the
remaining properties.  The Company believes that it has satisfactory title to
such properties in accordance with standards generally accepted in the oil and
gas industry.  A title opinion is obtained prior to the commencement of any
drilling operations on such properties.  The Company's properties are subject to
customary royalty interests, liens incident to operating agreements, liens for
current taxes and other burdens which the Company believes do not materially
interfere with the use of or affect the value of such properties.  Substantially
all of the Company's oil and gas properties are and will continue to be
mortgaged to secure borrowings under the Company's credit facilities.

OPERATIONAL HAZARDS AND INSURANCE

     The operations of the Company are subject to all risks inherent in the
exploration for and production of oil and gas, including such natural hazards as
blowouts, cratering and fires, which could result in damage or injury to, or
destruction of, drilling rigs and equipment, formations, producing facilities or
other property, or could result in personal injury, loss of life or pollution of
the environment.  Any such event could result in substantial expense to the
Company which could have a material adverse effect upon the financial condition
of the Company to the extent it is not fully insured against such risk.  The
Company carries insurance against certain of these risks but, in accordance with
standard industry practice, the Company is not fully insured for all risks,
either because such insurance is unavailable or because the Company elects not
to obtain insurance coverage because of cost.  Although such operational risks
and hazards may to some extent be minimized, no combination of experience,
knowledge and scientific evaluation can eliminate the risk of investment or
assure a profit to any company engaged in oil and gas operations.

EMPLOYEES

     The Company employs a total of seven full time personnel at its offices in
Tulsa, Oklahoma and one field employee in the state of Texas.  The Company also
engages the services of 17 additional contract field personnel.  The Company
believes its relations with its employees and contractors are excellent.

RESULTS OF OPERATIONS

     The Company follows the "successful efforts" method of accounting for its
oil and gas properties whereby costs of productive wells and productive leases
are capitalized and depleted on a unit-of-production basis over the life of the
remaining proved reserves.  Depletion of capitalized costs is provided on a
well-by-well basis.  Exploratory expenses, including geological and geophysical
expenses and annual delay rentals, are charged to expense as incurred.
Exploratory drilling costs, including the cost of stratigraphic test wells, are
initially capitalized, but charged to expense if and when the well is determined
to be unsuccessful.

     The factors which most significantly affect the Company's results of
operations are (i) the sale prices of crude oil and natural gas, (ii) the level
of oil and gas sales, (iii) the level of lease operating expenses, (iv) the
level of exploratory activities, and (v) the level of and interest rates on
borrowings.  Total sales volumes and the level of borrowings are significantly
impacted by the degree of success the Company experiences in its efforts to
acquire oil and gas properties and its ability to maintain or increase
production from existing oil and gas properties through its development and
production enhancement activities.  The following table reflects certain
historical operating data for the periods presented.

     Relatively modest changes in either oil or gas prices significantly impact
the Company's results of operations and cash flow and could significantly impact
the Company's borrowing capacity.  Prices received by the Company for sales of
oil and natural gas have fluctuated significantly from period to period. The
Company's ability to maintain current borrowing capacity and to obtain
additional capital on attractive terms is substantially dependent on oil and gas
prices. Domestic spot oil prices have ranged from a low of approximately $11 per
barrel in July 1986 to a high of approximately $40 per barrel in October 1991,
with a current price of approximately $18.50 per barrel.  The fluctuations in
oil prices during these periods reflect market uncertainty regarding OPEC's
ability to control the production of its member countries, as well as concerns
related to the global supply and demand for crude oil.  Since the end of the
Gulf War in early 1991, crude oil prices have experienced continued weakness,
primarily as a result of OPEC's inability to maintain disciplined production
quotas by member countries and the uncertainty associated with Iraq's return to
the crude oil export market.  These factors continue to overhang the market and
will create significant price volatility for the foreseeable future.

     Natural gas prices received by the Company fluctuate generally with changes
in the spot market price for gas.  Spot market gas prices have generally
declined in recent years because of lower worldwide energy prices as well as
excess deliverability of natural gas in the United States.  However, natural gas
prices have rebounded recently and appear to be poised for further
strengthening. Domestic spot natural gas prices have ranged from a low of
approximately $0.90 per Mcf in January 1992 to a high of approximately $4.44 per
Mcf in December 1996, with a current price of approximately $3.25 per Mcf.
Environmental concerns coupled with recent increases in the use of natural gas
to produce electricity have combined to improve prices.  As part of continued
deregulation of natural gas, U.S. pipelines have been made more accessible to
both buyers and sellers of natural gas and, as a result, natural gas will be
able to more effectively compete for market share with other end-use energy
forms.

     The Company's principal source of cash flow is the production and sale of
its crude oil and natural gas reserves, which are depleting assets.  Cash flow
from oil and gas sales depends upon the

                                       19
<PAGE>
 
quantity of production and the price obtained for such production.  An increase
in prices permits the Company to finance its operations to a greater extent with
internally generated funds.  A decline in oil and gas prices reduces the cash
flow generated by the Company's operations, which in turn reduces the funds
available for servicing debt, acquiring additional oil and gas properties and
exploring for an developing new oil and gas reserves.

     In addition to the foregoing, the results of the Company's operations vary
due to seasonal fluctuations in the sales prices and volumes of natural gas.  In
recent years, natural gas prices have been generally higher in the fall and
winter.  Due to these seasonal fluctuations, results of operations for
individual annual and quarterly periods may not be indicative of results which
may be realized on an annual basis.

     The following events have directly affected the comparability of the
results of operations and financial position of the Company during the periods
presented:

     .    Effective April 1, 1995, the Company acquired all of the limited
          partners' interests in four oil and gas limited partnerships in which
          it was the sole general partner and liquidated the partnerships.  In
          addition, effective April 1, 1995, the Company acquired approximately
          74% and 96% of the limited partners' interest in two additional oil
          and gas limited partnerships in which the Company was also the sole
          general partner.  The consideration paid by the Company for these
          limited partnership interests was 1,349,900 shares of the Company's
          Common Stock, $8,392 in cash, and the assumption of approximately
          $611,000 in partnership debt.  The stock was valued at approximately
          $1,267,000 based upon the estimated value of the partnerships' oil and
          gas reserves.

     .    On December 1, 1995, the Company purchased the 50% partnership
          interest it did not already own in South Boulder Associates, Ltd. and
          liquidated the partnership.  The Company previously owned a 50%
          interest in this partnership and was the general partner.  South
          Boulder Associates, Ltd. owned the office building located at 1850
          South Boulder Avenue, Tulsa, Oklahoma which is the location of the
          executive offices of the Company.  The purchase price for this
          partnership interest was $50,000 in cash and the assumption of
          approximately $168,000 in partnership debt.

     .    In December 1995, the Company acquired the producing oil and gas
          property known as the West Flowers Unit, located in Stonewall County,
          Texas.  The Company paid $625,000 for this property and expended an
          additional $134,485 in capitalized costs during the year ended
          December 31, 1996.  Sales of oil and gas from this property accounted
          for approximately 21% of the oil and gas revenues and approximately
          18% of the lease operating expense of the Company during the year
          ended December 31, 1996.

     .    In January 1996, the Company acquired the producing oil and gas
          property known as the Northwest Antelope Mississippi Chat Unit,
          located in Noble and Garfield Counties, Oklahoma.  The Company paid
          $152,500 for this property and incurred an additional $218,113 in
          capitalized costs on the property during the year ended December 31,
          1996.  Sales of oil and gas from this property accounted for
          approximately 9% of the oil and gas revenues and approximately 18% of
          the lease

                                       20
<PAGE>
 
          operating expenses of the Company for the year ended December 31,
          1996.

     .    In May 1996, the Company acquired the remaining limited partnership
          interests which it had not acquired in April 1995 in two oil and gas
          limited partnerships which the Company then liquidated.  The
          consideration paid for these interests was 46,320 shares of Common
          Stock which was valued at approximately $59,000 based on the estimated
          value of the partnership oil and gas assets acquired.

     Year ended December 31, 1996 compared to year ended December 31, 1995.
Total revenues for the year ended December 31, 1996 increased 55.9% to
$1,797,717 compared to $1,152,532 for the year ended December 31, 1995.  Oil and
gas revenues increased from $983,841 for the year ended December 31, 1995 to
$1,675,193 for the year ended December 31, 1996.  These increases were
attributable to both increases in production and increases in average prices
received during the year.  Average prices received by the Company were $20.85
per Bbl of oil and $1.86 per Mcf of gas during fiscal 1996 compared to $18.34
per Bbl of oil and $1.31 per Mcf of gas received during fiscal 1995.

     Oil and gas production for the year ended December 31, 1996 was 18,694 Bbls
and 47,167 Mcf higher than production volumes experienced during the prior year.
These production increases were primarily attributable to the production from
producing oil and gas properties purchased in December 1995 and January 1996.
Production from the Northwest Antelope Mississippi Chat Unit, which the Company
acquired in January 1996, amounted to 4,919 Bbls of oil and 21,029 Mcf of gas
during fiscal 1996 and production from the West Flowers Unit, which the Company
acquired in December 1995, amounted to 16,294 Bbls of oil and 4,627 Mcf of gas
during fiscal 1996.

     Operating income declined from $168,891 during the year ended December 31,
1995 to $122,524 during the year ended December 31, 1996.  The decline is
attributable to the loss of operating revenues received from the various limited
partnerships which were acquired by the Company in April 1995.  Prior to their
acquisition, the Company had charged these partnerships for administrative
overhead and field supervision in connection with the Company's activities in
operating the wells for the partnerships.  The Company continues to charge third
party working interest owners these overhead fees on a monthly basis on wells
that the Company operates.

     Lease operating expenses increased from $473,927 during 1995 to $725,432
during the year ended December 31, 1996.  Lease operating expense is comprised
of the normal and recurring expenses incurred in the operation of oil and gas
wells, production taxes, compression and dehydration fees and transportation
costs.  Normal and recurring lease operating expense increased from $410,198 in
fiscal 1995 to $624,074 during fiscal 1996.  Oil and gas properties acquired
during December 1995 and January 1996 accounted for approximately $238,200 of
this increase while normal lease operating expense on wells the Company owned
during both fiscal 1995 and 1996 declined by approximately $24,300 due to more
efficient operating procedures.  Production taxes during 1996 amounted to
$96,939 compared to $57,446 in the prior year.  The increase in taxes is a
direct result of increased revenue from oil and gas sales experienced during the
year ended December 31, 1996.  Compression and dehydration fees increased from
$1,889 during fiscal 1995 to $3,304 during fiscal 1996 and transportation costs
paid by the Company declined to $1,114 during fiscal 1996 from $4,394 during the
prior year.

     Compensation expense increased from $273,953 during fiscal 1995 to $375,482
during fiscal

                                       21
<PAGE>
 
1996.  Approximately $70,000 of this increase is a result of the inclusion of a
full year's salary for two executive officers who joined the Company in
September and December 1995.  The remainder of the increase is attributable to
increases in compensation to existing employees.

     Depreciation, depletion and amortization expense for the year ended
December 31, 1996 was $318,556 compared to $302,618 for the prior year.
Depletion of oil and gas assets is based on a unit of production method and
support equipment is depreciated over its estimated useful life.  The increase
is attributable to both increased production of oil and gas during 1996 and
increased capitalized costs being depleted during the year.  The increase in
capitalized costs is primarily attributable to the purchase of producing oil and
gas properties during December 1995 and January 1996.

     General and administrative expenses for the year ended December 31, 1996
increased to $378,535 from $364,280 for the prior year reflecting primarily
increases in professional fees, insurance costs, and travel and transportation
costs.

     Other expense increased from $106,191 in 1995 to $252,156 in 1996.  This
increase is comprised primarily of the loss from operations for the office
building which the Company owns and the increase in interest expense.  During
December 1995, the Company acquired the remaining outside interest in the
partnership which owned the office building in which its executive offices are
located.  During fiscal 1995, the Company paid rent to this partnership in the
amount of $25,800.  Interest expense increased from $97,252 during fiscal 1995
to $233,411 during fiscal 1996.  The increase is attributable to both the debt
assumed when the Company acquired the oil and gas limited partnerships during
the year and the additional debt incurred to purchase producing oil and gas
properties acquired in December 1995 and January 1996.

     Year ended December 31, 1995 compared to year ended December 31, 1994.  The
Company's operations for the year ended December 31, 1995 include nine months of
activity of six oil and gas limited partnerships in which the company was the
general partner.  These partnership interests were acquired from the limited
partners in exchange for Common Stock of the Company effective April 1, 1995.

     Total revenues were $1,152,532 for the year ended December 31, 1995
compared to $811,202 for the year ended December 31, 1994.  This represents a
42% increase in total revenues for the period.  Oil and gas revenues for the
period ended December 31, 1995 were $983,841 with $700,408 coming from oil sales
and $283,433 from gas sales.  Oil sales were based on the sale of 38,177 barrels
at an average price of $18.34 per barrel.  Gas sales were based on the sale of
215,956 Mcf at an average price of $1.31 per Mcf.  Operating income, which
consists of revenues received from other working interest holders in wells that
the Company operates including reimbursement of allocated Company overhead,
field supervision overhead, and compressor fee income, amounted to $168,691 for
the year ended December 31, 1995 compared to $255,638 for the year ended
December 31, 1994.  The decline in operating income during the year ended
December 31, 1995 was almost entirely attributable to the loss of revenues from
the limited partnerships which were acquired by the Company in fiscal 1995.

     Lease operating expenses for the year ended December 31, 1995 were $473,927
compared to $251,024 for the year ended December 31, 1994.  This increase is
primarily a result of the inclusion of lease operating expenses associated with
the oil and gas properties owned by the limited partnerships acquired by the
Company in fiscal 1995.  Lease operating expenses include production taxes paid,

                                       22
<PAGE>
 
compression and dehydration charges, transportation fees paid, and normal
operating expenses incurred.

     Depreciation, depletion and amortization expenses increased to $302,618 for
the year ended December 31, 1995 from $109,214 for the prior year.  The increase
is primarily a result of depreciation and depletion expenses incurred on oil and
gas properties which were previously owned by the limited partnerships acquired
by the Company.

     General and administrative and compensation expense were $638,233 during
the year ended December 31, 1995 compared with $693,509 for the year ended
December 31, 1994.  The reduction in these expenses is primarily a result of a
decrease in bad debt expense associated with non-payment of invoices by outside
working interest owners on wells operated by the Company.

     Interest expense for the year ended December 31, 1995 amounted to $97,252
compared to $41,640 for the year ended December 31, 1994.  This increase is
attributable to the assumption, by the Company, of notes payable which were
previously liabilities of the limited partnerships acquired by the Company.

     Net gain on the sale of assets during the year ended December 31, 1995
amounted to $5,777 compared to $113,112 for the year ended December 31, 1994.
During the year ended December 31, 1994 the Company sold three oil and gas
properties to third parties and realized significant gains on the sale.  During
the year ended December 31, 1995 the Company sold a greater number of oil and
gas properties, but the properties sold had been developed by the Company, were
approaching the end of their economic lives, and were sold at lower prices for
only slight losses or gains.

CAPITAL RESOURCES AND LIQUIDITY

     The Company's capital requirements relate primarily to the acquisition of
developed oil and gas properties and undeveloped leasehold acreage and
exploration and development activities.  In general, because the Company's oil
and gas reserves are depleted by production, the success of its business
strategy is dependent upon a continuous acquisition and exploration and
development program.

     The domestic spot price for crude oil has ranged from $11.00 to $40.00 per
barrel over the past ten years.  To the extent that crude oil prices continue
fluctuating in this manner, the Company expects material fluctuations in
revenues from quarter to quarter which, in turn, could adversely affect the
Company's ability to timely service its debt to its principal banks and fund its
ongoing operations and could, under certain circumstances, require a write-down
of the book value of the Company's oil and gas reserves.

     Since the Company is engaged in the business of acquiring producing oil and
gas properties, from time to time it acquires certain non-strategic and marginal
properties in some of its purchases.  A portion of the Company's on-going
profitability is related to the disposition of these non-strategic properties on
a regular basis.  The  Company expects to continue to pursue sales of these
types of properties in the future.  In most cases the revenue from these
properties is insignificant and in many cases does not exceed the lease
operating expense.  As a result, a portion of the Company's capital resources
are generated by the sale of assets from continuing operations.  Sales of non-
strategic and

                                       23
<PAGE>
 
minor interests oil and gas properties accounted for $7,326 in losses during
fiscal 1996 and $5,777 in gains during fiscal 1995.

     Capital Expenditures.  The timing of most of the Company's capital
expenditures is discretionary.  Currently there are no material long-term
commitments associated with the Company's capital expenditure plans.
Consequently, the Company has a significant degree of flexibility to adjust the
level of such expenditures as circumstances warrant.  The Company primarily uses
internally generated cash flow and proceeds from the sale of oil and gas
properties to fund capital expenditures, other than significant acquisitions,
and to fund its working capital needs.  If the Company's internally generated
cash flows should be insufficient to meet its debt service or other obligations,
the Company may reduce the level of discretionary capital expenditures or
increase the sale of non-strategic oil and gas properties in order to meet such
obligations.  The level of the Company's capital expenditures will vary in
future periods depending on energy market conditions and other related economic
factors.  The Company anticipates that its cash flow will be sufficient to fund
its operations and debt service at their current levels for the next year.

     Substantially all of the Company's capital expenditures have been made to
acquire oil and gas properties.  During the year ended December 31, 1995, the
Company completed five acquisitions of oil and gas properties for a cost of
approximately $2,246,000, including the value of the oil and gas properties
acquired by the Company in connection with the acquisition of 100% of the
limited partners' interest in four limited partnerships and approximately 74%
and 97% of the limited partners' interest in two additional limited
partnerships, respectively, for a total of 1,349,900 shares of the Company's
Common Stock, $8,392 in cash and the assumption of approximately $611,000 in
partnership debt.  During the year ended December 31, 1996, the Company
completed three acquisitions of oil and gas properties for a cost of
approximately $222,000, including the value of the remaining limited partners'
interest in the two limited partnerships which were not 100% acquired in fiscal
1995.  These remaining limited partnership interests were acquired for 46,320
shares of the Company's Common Stock.  The Company's strategy is to continue to
expand its reserve base principally through acquisitions of producing oil and
gas properties.  As a result, it is likely that capital expenditures will exceed
cash provided by operating activities in years where significant growth occurs
in the Company's oil and gas reserve base. In such cases, additional external
financing will be required.

     The Company intends to continue its practice of reserve replacement and
growth through the acquisition of producing oil and gas properties, although at
this time it is unable to predict the number and size of such acquisitions, if
any, which will be completed.  The Company's ability to finance its oil and gas
acquisitions is determined by its cash flow from operations and available
sources of debt and equity financing.

     Financing Arrangements.  To date, the Company has financed its acquisitions
of oil and gas properties primarily through bank borrowings and issuance of
Common Stock.  At December 31, 1996, the Company was indebted to three principal
lenders in the aggregate amount of $2,176,603.  Aggregate monthly payments on
this indebtedness are approximately $63,000 and interest rates range from 8.6%
to 10.0%.  At maturity of this indebtedness, which will occur from May 1997 to
March 2001, principal amounts due will range from $25,000 to $682,000.  The
Company anticipates that at maturity it will be able to refinance this
indebtedness as necessary on satisfactory terms.  Substantially all of the
Company's oil and gas properties are subject to mortgages granted to secure this
debt.

                                       24
<PAGE>
 
     The Company owns the office building in Tulsa, Oklahoma in which its
executive offices are located.  The Company financed the acquisition of this
building through borrowing from a bank.  At December 31, 1996, the Company was
indebted to this bank in the principal amount of $210,969.  This loan bears
interest at the rate of 9.5% per year, and requires monthly payments of $2,261,
with approximately $175,000 due at maturity in March 2001.  The Company has
granted a mortgage on the building to secure this debt.

     For additional information regarding the indebtedness of the Company at
December 31, 1996, see Note 5 to the Company's Consolidated Financial Statements
elsewhere in this Registration Statement.

SEASONALITY

     The results of operations of the Company are somewhat seasonal due to
seasonal fluctuations in the price for crude oil and natural gas.  Recently,
crude oil prices have been generally higher in the third calendar quarter and
natural gas prices have been generally higher in the first calendar quarter.
Due to these seasonal fluctuations, results of operations for individual
quarterly periods may not be indicative of results which may be realized on an
annual basis.

INFLATION AND PRICES

     In recent years, inflation has not had a significant impact on the
Company's operations or financial condition.  The generally downward pressure on
oil and gas prices during most of such periods has been accompanied by a
corresponding downward pressure on costs incurred to acquire, develop and
operate oil and gas properties as well as the costs of drilling and completing
wells on properties.


ITEM 3.   DESCRIPTION OF PROPERTY

OIL AND GAS PROPERTIES

     All of the Company's oil and gas properties, reserves and activities are
located onshore in the continental United States in the states of Texas and
Oklahoma.  There are no quantities of oil or gas produced by the Company which
are subject to long-term supply or similar agreements with foreign governmental
authorities.

     Oil and Gas Reserves.  Sycamore Resources, LLC ("Sycamore Resources)", an
independent petroleum engineering consulting firm, has made estimates of the
Company's oil and gas reserves as of January 1, 1997. Sycamore Resources' report
covers the estimated present value of future net cash flows before income taxes
(discounted at 10%) attributable to the Company's proved developed reserves, as
well as its proved undeveloped reserves and estimated future net cash flows from
such reserves. The Sycamore Resources report includes the Company's oil and gas
properties located in the state of Kansas which have subsequently been sold, and
does not include the Company's royalty interests in 14 wells located in the
state of Ohio which are not material to the Company's total oil and gas
reserves.

                                       25
<PAGE>
 
     The quantities of the Company's proved reserves of oil and natural gas
presented below include only those amounts which the Company reasonably expects
to recover in the future from known oil and gas reservoirs under existing
economic and operating conditions.  Proved developed reserves are limited to
those quantities which are recoverable commercially at current prices and costs,
under existing regulatory practices and with existing technology.  Accordingly,
any changes in prices, operating and development costs, regulations, technology
or other factors could significantly increase or decrease estimates of the
Company's proved developed reserves.  The Company's proved undeveloped reserves
include only those quantities which the Company reasonably expects to recover
from the drilling of new wells based on geological evidence from offsetting
wells.  The risks of recovering these reserves are higher from both geological
and mechanical perspectives than the risks of recovering proved developed
reserves.

     Set forth below are estimates of the Company's net proved reserves and
proved developed reserves and the estimated future net revenues from such
reserves and the present value thereof based upon the standardized measure of
discounted future net cash flows relating to proved oil and gas reserves in
accordance with the provisions of Statement of Financial Accounting Standards
No. 69.  "Disclosures about Oil and Gas Producing Activities."  Estimated future
net cash flows from proved reserves are determined by using estimated quantities
of proved reserves and the periods in which they are expected to be developed
and produced based on economic conditions at the date of the report.  The
estimated future production is priced at current prices at the date of the
report.  The resulting estimated future cash inflows are then reduced by
estimated future costs to develop and produce reserves based on cost levels at
the date of the report.  No deduction has been made for depletion, depreciation
or income taxes or for indirect costs, such as general corporate overhead.
Present values were computed by discounting future net revenues at 10% per
annum.

     The following table sets forth estimates of the proved oil and natural gas
reserves of the Company as of January 1, 1997, as evaluated by Sycamore
Resources.

     in the state of Kansas.  See "Sale of Kansas Oil and Gas Properties."

     The following table sets forth amounts as of December 31, 1996 determined
in accordance with the requirements of the applicable accounting standards, of
the estimated future net cash flows from production and sale of the proved
reserves attributable to the Company's oil and gas properties before income

     The estimation of oil and gas reserves is a complex and subjective process
which is subject to continued revisions as additional information becomes
available.  Reserve estimates prepared by different engineers from the same data
can vary widely.  Therefore, the reserve data presented herein should not be
construed as being exact.  Any reserve estimate depends in part on the quality
of available data, engineering and geologic interpretation, and thus represents
only an informed professional judgment.  Subsequent reservoir performance may
justify upward or downward revision of such estimate.

     Estimates of the Company's proved reserves have never been filed or
included in reports to any federal authority or agency.

     For further information on reserves, costs relating to oil and gas
activities, and results of operations from producing activities, see Note 16 to
the Company's Consolidated Financial Statements - Supplementary Financial
Information About Oil and Gas Producing Activities (unaudited).

(1)  The components of production costs may vary substantially among wells
     depending on the methods of recovery employed and other factors, but
     generally include production taxes, lease overhead, maintenance and repair,
     labor and utilities.

     Drilling Activity.  During the years ended December 31, 1995 and 1996, the
Company did not drill or participate in the drilling of any exploratory or
development wells.  To the extent the Company engages in drilling activities in
the future other than horizontal drilling activities (See "Item 1. Description
of Business - Horizontal Drilling"), all such activities will be conducted with
independent contractors.  The Company currently owns no drilling equipment.

     Sale of Kansas Oil and Gas Properties.  Effective February 1, 1997, the
Company sold all of its producing oil and gas properties in the state of Kansas.
This sale included 7 gross (5.6 net) wells which had average daily gross
production of 20.5 (12.9 net) barrels of oil per day.  Total proved developed
oil reserves at December 31, 1996 amounted to 33,010 barrels of oil.  There were
no proved undeveloped oil reserves associated with these properties.  The sale
price received by the Company was $120,000 which resulted in a gain on sale of
assets of approximately $52,000.

OFFICE FACILITIES

     The Company owns the office building in Tulsa, Oklahoma in which its
executive offices are located.  The Company occupies approximately 2,862 square
feet of space in this building with the remaining 5,724 square feet available
for rental to third parties.  At present, approximately 1,430 square feet are
unoccupied.  The building is subject to a mortgage in the current principal
amount of $210,969 payable in monthly installments of $2,261 until March 2001 at
which time the balance of approximately $175,000 will be due.  The Company
believes this facility is adequate for its present requirements.  Except for
this office building, the Company owns no material properties other than its oil
and gas properties.

year, respectively. In addition, Messrs. Livingston and Kemendo are entitled to
participate in all benefit programs the Company makes available to employees.
Under their agreements, Messrs. Livingston and Kemendo are eligible to
participate in the Company's incentive compensation bonus plan. See "Bonus
Plan". The Company has the right to terminate each of these employment
agreements upon written notice and, unless the agreement has been terminated for
cause, as defined, the Company is obligated to pay the terminated individual the
compensation payable for the remainder of the term of his agreement, including
any incentive compensation, vacation pay or accrued employee benefits. Messrs.
Livingston and Kemendo each have the right to terminate their employment
agreements with the Company upon 30 days written notice to the Company in which
event the Company is only obligated to compensate the individual up to the date
of termination. Each of the Employment Agreements also contain certain
provisions restricting Messrs. Livingston and Kemendo from engaging in business
activities in competition with the Company.

ITEM 7.   CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

     Until December 1, 1995, the Company leased its executive offices in Tulsa
Oklahoma from a partnership in which the Company was a general partner and owned
a 50% interest. During 1995, $25,800 was paid to the partnership as rent.
Effective December 1, 1995, the Company acquired the remaining 50% interest in
the partnership for $50,000 in cash and assumption of approximately $168,000 of
partnership debt. The partnership was then liquidated. See "Item 3. Description
of Properties - Office Facilities".

     Through August 1995, the Company sold gas produced from certain wells it
operates to a gas marketing company owned by Sid L. Anderson, Chairman of the
Board, President and Chief Executive Officer of the Company. Such sales for the
year ended December 31,1995 were approximately $89,000. The gas marketing
company collected a 3% commission on the resale of such gas, which was utilized
to pay income and other taxes of the gas marketing company. Effective September
1, 1995, the Company began to sell gas produced from the wells to an
unaffiliated purchaser.

     In 1995, the Company began paying a fee to Sid L. Anderson, Chairman of the
Board, President and Chief Executive Officer of the Company, pursuant to the
terms of a Guaranty Fee Agreement. Under the terms of this Agreement, Mr.
Anderson receives an annual fee for guaranteeing Company debt equal to the
greater of $15,000 or 3% of the guaranteed debt. During 1996 and 1995, fees paid
to Mr. Anderson under this Agreement were approximately $76,000 and $30,000,
respectively. See "Item 6. Executive Compensation - Employment Agreements".

     The Company incurs fees for tax and accounting services provided by a firm
in which Clayton E. Woodrum, Executive Vice President and a Director of the
Company, is a partner. Amounts paid by the Company to this firm during 1996 and
1995 were $39,943 and $34,476, respectively. In addition, during 1996, the
Company issued a total of 35,700 shares of Common Stock to this firm in payment
for services rendered. The value assigned to this stock, $49,980, was based on
billings received from the firm. At the request of the firm, 17,850 of these
shares were issued to Pat Woodrum, spouse of Clayton E. Woodrum, and 17,850 of
these shares were issued to Andrea Kemendo, spouse of a

                                       36
<PAGE>
 
     partner in the firm.

          During October, 1995 the Company purchased two producing oil and gas
     properties from KATO Operating Company ("KATO"), Livingston Oil and other
     third parties for a purchase price of $975,000. Subsequent to this
     transaction, Mr. B. E. Livingston, who is the President and owner of both
     KATO and Livingston Oil, was elected as a Director of the Company. The
     producing properties purchased consisted of a field containing 10 producing
     wells and several shut-in wells and a group of five producing leases which
     contain a total of nine producing wells. Additionally, in January, 1996 the
     Company purchased a producing oil and gas property from several individuals
     and entities, including an affiliate of KATO, for $152,000. KATO was the
     operator of the property purchased and the interest acquired from the KATO
     affiliate amounted to a 2.03% working interest in the property. These
     transactions were reviewed by the Board of Directors and were determined,
     based on negotiations that occurred at the time, to be on terms no less
     favorable to the Company than could have been obtained at the time and
     under the same circumstances from non-affiliated persons.

          During 1995, the Company paid $5,000 to McKittrick and Associates and
     paid $20,000 and issued 12,205 shares of Common Stock, valued at $1.39 per
     share, to Southern Financial Group, Inc. for investment banking services
     rendered in connection with the acquisition by the Company of limited
     partner interests in six limited partnerships in which the Company was the
     sole general partner. Mr. C. Dennis McKittrick, a Director of the Company,
     is the President of McKittrick and Associates and President and Chief
     Executive Officer of Southern Financial Group, Inc. Management believes,
     based on negotiations that occurred at the time, that these transactions
     were no less favorable to the Company than could have been obtained at the
     time and under the same circumstances from non-affiliated persons.

          Pursuant to an agreement signed in February 1996, B. E. (Bud)
     Livingston, a member of the Company's Board of Directors, will provide
     evaluation and reservoir engineering services to the Company with respect
     to oil and gas wells in Coal County, Oklahoma and Borden and Stonewall
     Counties, Texas in exchange for an amount equal to the net of a percentage
     of the net revenue interest and a percentage of the lease operating
     expenses attributable to certain producing oil and gas wells located in
     Garfield and Noble Counties, Oklahoma. During 1996, no amounts were paid by
     the Company to Mr. Livingston pursuant to this Agreement.

     ITEM 8.   DESCRIPTION OF SECURITIES

          On February 18, 1997, the Company declared a four-for-one stock split
     in the form of a stock dividend payable to the Company's shareholders of
     record on April 1, 1997. All references to outstanding shares, share
     ownership and per share amounts in this Registration Statement are
     presented giving effect to such stock dividend.

          The authorized capital stock of the Company consists of 25,000,000
     shares of Common Stock, par value $0.01 per share ("Common Stock"), and
     25,000,000 shares of Preferred Stock, par value $0.05 per share ("Preferred
     Stock"). As of the date of this Registration Statement, the Company had
     3,233,560 issued and outstanding shares of Common Stock, excluding
     1,081,250 shares held by the Company as treasury stock. No shares of
     Preferred Stock are issued and outstanding as of the effective date of this
     Registration Statement.

                                       37
<PAGE>
 
     The following description of certain matters relating to the capital stock
of the Company is a summary and is qualified in its entirety by the provisions
of the Company's Certificate of Incorporation and Bylaws, copies of which have
been filed with the Securities and Exchange Commission as exhibits to this
Registration Statement.

COMMON STOCK

     The holders of Common Stock are entitled to one vote per share on all
matters submitted to a vote of shareholders of the Company. In addition, such
holders are entitled to receive ratably such dividends, if any, as may be
declared from time to time by the Board of Directors out of funds legally
available therefor, subject to the preferential right to receive dividends with
respect to any Preferred Stock that from time to time may be outstanding. In the
event of the dissolution, liquidation or winding up of the Company, the holders
of Common Stock are entitled to share ratably in all assets remaining after
payment of all liabilities of the Company and subject to the prior distribution
rights of the holders of any Preferred Stock that may be outstanding at that
time. The holders of Common Stock do not have cumulative voting rights or
preemptive or other rights to acquire or subscribe for additional, unissued or
treasury shares. All outstanding shares of Common Stock are fully paid and
nonassessable.

PREFERRED STOCK

     The Board of Directors has the authority to issue 25,000,000 shares of
Preferred Stock, in one or more series, and to fix the rights, preferences,
qualifications, privileges, limitations or restrictions of each such series
without any further vote or action by the shareholders, including the dividend
rights, dividend rate, conversion rights, voting rights, terms of redemption
(including sinking fund provisions), redemption price or prices, liquidation
preferences and the number of shares constituting any series or the designations
of such series. No shares of Preferred Stock have ever been issued, and the
Company has no present plans to issue any Preferred Stock.

STOCKHOLDER ACTION

     Pursuant to the Company's Certificate of Incorporation, with respect to any
act or action required of or by the holders of the Company's Common Stock, the
affirmative vote of the holders of a majority of the issued and outstanding
Common Stock entitled to vote thereon is sufficient to authorize, affirm, ratify
or consent to such act or action, except as otherwise provided by law.

     The Bylaws of the Company provides that shareholders may take certain
action without the holding of a meeting by written consent or consents signed by
the holders of a majority of the outstanding shares of the capital stock of the
Company entitled to vote thereon. Prompt notice of the taking of any action
without a meeting by less than unanimous consent of the stockholders will be
given to those stockholders who do not consent in writing to the action. The
purposes of this provisions are to facilitate action by stockholders and to
reduce the corporate expense associated with annual and special meetings of
stockholders. Pursuant to rules and regulations of the Commission, if
stockholder action is taken by written consent, the Company will be required to
send each stockholder entitled to vote on the matter acted on, but whose consent
was not solicited, an information statement containing information substantially
similar to that which would have been contained in a proxy statement.

                                       38
<PAGE>
 
CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK

     The Company's authorized but unissued capital stock consists of 21,766,440
shares of Common Stock (including 1,081,250 shares held in treasury) and
25,000,000 shares of Preferred Stock.  One of the effects of the existence of
authorized but unissued capital stock may be to enable the Board of Directors to
render more difficult or to discourage an attempt to obtain control of the
Company by means of a merger, tender offer, proxy contest or otherwise, and
thereby to protect the continuity of the Company's management.  If in the due
exercise of its fiduciary obligations, for example, the Board of Directors were
to determine that a takeover proposal was not in the Company's best interests,
such shares could be issued by the Board of Directors without stockholder
approval in one or more private offerings or other transactions that might
prevent or render more difficult or costly the completion of the takeover
transaction by diluting the voting or other rights of the proposed acquirer or
insurgent stockholder or stockholder group, by creating a substantial voting
block in institutional or other hands that might undertake to support the
position of the incumbent Board of Directors, by effecting an acquisition that
might complicate or preclude the takeover, or otherwise.  In this regard, the
Company's Certificate of Incorporation grants the board of Directors broad power
to establish the rights and preferences of the authorized and unissued shares of
Preferred Stock, one or more series of which could be issued entitling holders
to vote separately as a class on any proposed merger or consolidation, to
convert shares of Preferred Stock into a larger number of shares of Common Stock
or other securities, to demand redemption at a specified price under prescribed
circumstances related to a change in control, or to exercise other rights
designed to impede a takeover.  The issuance of shares of Preferred Stock
pursuant to the Board's authority described above could decrease the amount of
earnings and assets available for distribution to holders of Common Stock, and
adversely affect the rights and powers, including voting rights, of such holders
and may have the effect of delaying, deferring or preventing a change in control
of the Company.  The Board of Directors does not currently intend to seek
stockholder approval prior to any issuance of authorized but unissued stock,
unless otherwise required by law.

CERTIFICATE OF INCORPORATION AND BYLAWS

     Under Oklahoma law, the exclusive power to adopt, amend and repeal bylaws
of a corporation is conferred solely upon the shareholders unless the
corporation's certificate of incorporation also confers such power upon its
Board of Directors.  Under the Company's Certificate of Incorporation, the Board
of Directors has been granted this power.  The Company's Bylaws also provide
that the number of directors shall be no fewer than three and no greater than
nine as fixed from time to time by resolution of the board of Directors.  These
provisions, in addition to the existence of authorized but unissued capital
stock, may have the effect, either alone or in combination with each other, of
making more difficult or discouraging an acquisition of the Company deemed
undesirable by the Board of Directors.

OKLAHOMA TAKEOVER STATUTES

     Upon this Registration Statement becoming effective, the Company will
become subject (unless the Company's Certificate of Incorporation is amended by
the Company's shareholders to be excluded) to the control share provisions of
Section 1090.1 of the Oklahoma General Corporation Act ("OGCA").  Generally, and
subject to various conditions and exceptions, the control share provisions of
the OGCA deny voting rights to "control shares" of a public company meeting
certain jurisdictional

                                       39
<PAGE>
 
nexus requirements.  "Control shares" are shares acquired by a person that, when
added to other shares owned by the "acquiring person," have voting power in the
election of directors within any of the following ranges:  20% or more but less
than 33 1/3%; 33 1/3% or more but less than a majority; or a majority or more.
Full voting rights may be returned by resolution of the shareholders approved by
a majority vote of all voting power, excluding interested shares.

     The Company is also subject to Section 1090.3 of the OGCA which in general,
prevents an "interested shareholder" from engaging in a "business combination"
with an Oklahoma corporation for three years following the date such person
became an interested shareholder, unless (i) prior to the date such person
became an interested shareholder, the board of directors of the corporation
approved the transaction in which the interested shareholder became an
interested shareholder or approved the business combination; (ii) upon
consummation of the transaction that resulted in the interested shareholder's
becoming an interested shareholder, the interested shareholder owns at least 85%
of the voting stock of the corporation outstanding at the time the transaction
commenced (excluding stock held (x) by directors who are also officers of the
corporation and (y) by employee stock plans that do not provide employees with
the rights to determine confidentially whether shares held subject to the plan
will be tendered in a tender or exchange offer); or (iii) on or subsequent to
the date of the transaction in which such person became an interested
shareholder, the business combination is approved by the board of directors of
the corporation and authorized at a meeting of shareholders by the affirmative
vote of the holders of two-thirds of the outstanding voting stock of the
corporation now owned by the interested shareholder.  Under Section 1090.3, the
restrictions described above do not apply to certain business combinations
proposed by an interested shareholder following the announcement or notification
of one of a number of extraordinary transactions involving the corporation and a
person who had not been an interested shareholder during the previous three
years or who became an interested shareholder during the previous three years or
who became an interested holder with the approval of a majority of the
corporation's directors, if such extraordinary transaction is approved or not
opposed by a majority of the directors who were directors prior to any person
becoming an interested stockholder during the previous three years or were
recommended for election or elected to succeed such directors by a majority of
such directors.

     Section 1090.3 defines a "business combination" to include (i) any merger
or consolidation involving the corporation and an interested stockholder, (ii)
any sale, transfer, pledge or other disposition involving an interested
stockholder of 10% or more of the assets of the corporation, (iii) subject to
certain exceptions, any transaction which results in the issuance or transfer by
the corporation of any stock of the corporation to an interested stockholder,
(iv) any transaction involving the corporation which has the effect of
increasing the proportionate share of the stock of any class or series of the
corporation beneficially owned by the interested shareholder or (v) the receipt
by an interested shareholder of any loans, guarantees, pledges or other
financial benefits provided by or through the corporation.  In addition, Section
1090.3 defines an "interested shareholder" as any entity or person beneficially
owning 15% or more of the outstanding voting stock of the corporation and any
entity or person affiliated with or controlling or controlled by such an entity
or person.

SHAREHOLDER REPORTS

     The Company will furnish to its shareholders annual reports containing
audited financial statements reported on by independent auditors for each fiscal
year.  Quarterly reports containing unaudited financial information for the
first three quarters of each fiscal year will be furnished to a

                                       40

shareholder upon request.


                                    PART II

ITEM 1.  MARKET PRICE OF AND DIVIDENDS ON THE REGISTRANT'S COMMON EQUITY AND
         OTHER SHAREHOLDER MATTERS

MARKET INFORMATION

     The shares of Common Stock of the Company have limited transferability and
there is no established trading market for the Company's Common Stock.  Further,
there can be no predictions or assurance as to whether a trading market may
ultimately develop in the Company's Common Stock.  The Company has no present
plans or intentions to initiate any public offering of its Common Stock or other
securities in the foreseeable future, nor has the Company agreed to register any
of its outstanding shares of Common Stock under the Securities Act on behalf of
any shareholder.  To the extent that a public trading market develops in the
Company's Common Stock after the effective date of this Registration Statement,
such market would be in the general over-the-counter securities market.

HOLDERS

     In addition to the 3,233,560 shares of Common Stock currently issued and
outstanding, there are outstanding options to purchase a total of 642,500 shares
of Common Stock at exercise prices ranging from $1.30 to $1.40 per share.  Of
these options, 300,500 are currently exercisable.  In addition, there are
outstanding warrants to purchase 225,000 shares of Common Stock at exercise
prices ranging from $1.20 to $1.60 per share.

     As of March 17, 1997, the Company had 153 holders of record of its Common
Stock.

DIVIDENDS

     The Company has never paid any dividends on its Common Stock.  The Company
expects to retain all available earnings generated by its operations for the
development and growth of its business and does not anticipate paying any cash
dividends in the foreseeable future.  Any future determination as to the payment
of dividends will be made at the discretion of the Board of Directors and will
depend on a number of factors, including the future earnings, capital
requirements, financial condition and future prospects of the Company,
restrictions in the Company's current or future financing agreements and such
other factors as the Board of Directors may deem relevant.

TRANSFER AGENT

     The Company currently serves as its own transfer agent for the Company's
Common Stock.

SHARES ELIGIBLE FOR FUTURE SALE

     In general, under Rule 144, as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned restricted shares for at
least two years, including an "affiliate",

                                       41
<PAGE>
 
is entitled to sell, within any three-month period, a number of shares that does
not exceed the greater of (i) 1% of the then outstanding shares of the Company's
Common Stock or (ii) an amount equal to the average weekly reported volume of
trading in such shares during the four calendar weeks preceding such sale.
Sales under Rule 144 are also subject to certain manner of sale limitations,
notice requirements and the availability of current public information about the
Company.  A person (or persons whose shares are aggregated) who is not deemed an
"affiliate" of the Company and who has beneficially owned Restricted Shares for
at least three years is entitled to sell such shares under Rule 144 without
regard to these volume or other limitations.  Restricted shares properly sold in
reliance on Rule 144 are thereafter freely tradable without restriction or
registration under the Securities Act, unless thereafter held by an "affiliate"
of the Company.

     Of  the 3,233,560 shares of the Company's Common Stock outstanding,
1,418,750 are eligible for sale under Rule 144 immediately following the
effective date of this Registration Statement.  Substantially all of the
remaining 1,814,810 outstanding shares of Common Stock which are currently
subject to Rule 144 resale restrictions will be eligible for resale under Rule
144 commencing in November 1997 through January 1999.

     No predictions can be made of the effect, if any, of future public sales of
restricted shares or the availability of restricted shares for sale in the
public market.  Sales of substantial amounts of Common Stock under Rule 144
could adversely affect prevailing market prices.


ITEM 2.   LEGAL PROCEEDINGS

     The Company is not currently a party to any material legal proceeding.
From time to time the Company is a defendant in various legal proceedings which
are considered routine litigation incidental to the Company's business, the
disposition of which management does not anticipate will have a material effect
on the financial position or result of operations of the Company.


ITEM 3.   CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS

     Not applicable.


ITEM 4.   RECENT SALES OF UNREGISTERED SECURITIES

     Within the three-year period immediately preceding the filing date of this
Registration Statement, the Company issued securities not registered under the
Securities Act of 1933 (the "Securities Act") as set forth below.  In each such
transaction, an exemption from registration was claimed under Sections 3(b) or
4(2) of the Securities Act and regulations promulgated thereunder because no
public offering was involved and the securities were purchased for investment
and not with a view to the distribution thereof.  No underwriter was involved in
any of the stock transactions discussed below nor were any underwriting
discounts, except as noted, or commission paid.  Each certificate representing
shares issued bears a restrictive legend and stop transfer instructions were
entered on the Company's stock transfer records with respect thereto.

                                       42
<PAGE>
 
     In November 1995 (effective April 1, 1995) the Company exchanged a total of
1,337,695 newly issued shares of Common Stock, valued at $0.95 per share, $8,293
in cash and assumption of approximately $611,000 in debt for (i) 100% of the
limited partners' interests in four Oklahoma limited partnerships, (ii) 96% of
the limited partners' interest in an Oklahoma limited partnership, and (iii) 74%
of the limited partners' interest in an Oklahoma limited partnership.  Effective
May 31, 1996, the Company acquired the remaining limited partners' interests in
the latter two partnerships in exchange for 46,320 newly issued shares of the
Company's Common Stock, valued at $0.95 per share.  The Company was the sole
general partner in each of these partnerships which owned oil and gas properties
in the states of Oklahoma, Texas and Kansas.  The shares were issued to
approximately 90 limited partners in exchange for their limited partner
interests.  Subsequent to completion of the exchange, each of the partnerships
was liquidated and the oil and gas properties were conveyed to the Company as
the sole remaining partner.  The Company paid $5,000 to McKittrick and
Associates and $20,000 and 12,205 newly issued shares of Common Stock to
Southern Financial Group, Inc. as investment banking fees for their assistance
in completing the exchange.  C. Dennis McKittrick, President of McKittrick and
Associates and President and Chief Executive Officer of Southern Financial
Group, Inc., is a Director of the Company.

     In November 1995 the Company issued 168,750 shares of Common Stock to
Pangloss International, S.A. in partial payment of indebtedness of the Company.
For the purpose of this transaction, the Common Stock was valued at $0.33 per
share.


     During the period of January through November 1996 the Company issued a
total of 126,640 shares of Common Stock to 33 persons for a purchase price of
$1.40 per share paid in cash.

     In March 1996 the Company sold 87,500 shares of Common Stock to Pangloss
International, S.A. for a purchase price of $1.20 per share paid in cash.

     In January 1997 the Company issued a total of 35,700 shares of Common Stock
in payment for tax and accounting services rendered by the firm of Woodrum,
Wilson, Kemendo & Cuite, P.C. at a value of $1.40 per share.  At the request of
the firm, 17,850 of these shares were issued to Andrea Kemendo, spouse of a
partner in the firm, and 17,850 of these shares were issued to Pat Woodrum.  Pat
Woodrum is the wife of Clayton E. Woodrum, a partner with the firm and Executive
Vice President and a Director of the Company.

     The Company is currently conducting a private placement for up to 75,000
shares of the Company's Common Stock for a purchase price of $2.00 per share.
The offering period extends to March 31, 1997.


ITEM 5.   INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Amended and Restated Certificate of Incorporation of the Company
authorizes and the Amended and Restated Bylaws of the Company provide that the
Company shall indemnify its officers and directors to the fullest extent
permitted by applicable law.  Section 1031 of the Oklahoma General Corporation
Act (the "OGCA") provides, in general, that each director and officer of a
corporation may be indemnified against expenses (including attorneys' fees,
judgments, fines and amounts paid in

                                       43
<PAGE>
 
settlement) actually and reasonably incurred in connection with the defense or
settlement of any threatened, pending or completed legal proceedings in which he
is involved by reason of the fact that he is or was a director of officer of
such corporation, if he acted in good faith in a manner that he reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceedings, if he had no reasonable
cause to believe that his conduct was unlawful.  If the legal proceeding,
however, is by or in the right of the corporation, the director or officer may
not be indemnified in respect of any claim, issue or manner as to which he shall
have been adjudged to be liable to the corporation unless a court determines
otherwise.

     As permitted by Section 1006 of OGCA, the Amended and Restated Certificate
of Incorporation of the Company provides that no director of the Company shall
be personally liable to the Company or its stockholders for monetary damages for
breach of his fiduciary duty as a director, provided, however, that such
provision shall not apply to any liability of a director (1) for any breach of a
director's duty of loyalty to the Company or its stockholders, (2) for acts or
omissions that are not in good faith or involve intentional misconduct or a
knowing violation of the law, (3) under Section 1053 of the OGCA or (4) for any
transaction from which the director derived an improper personal benefit.


                                   PART F/S

     The Consolidated Financial Statements of the Company as of December 31,
1996 and 1995 included in this Registration Statement have been audited by an

Statement.

INDEPENDENT AUDITORS' REPORT


To the Board of Directors
Pan Western Energy Corporation:

We have audited the accompanying consolidated balance sheets of Pan Western
Energy Corporation and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for the years then ended.  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 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 overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the consolidated financial position of Pan Western Energy Corporation
and subsidiaries at December 31, 1996 and 1995 and the consolidated results of
their operations and their cash flows for the years then ended in conformity
with generally accepted accounting principles.

PAN WESTERN ENERGY CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1996 AND 1995
- --------------------------------------------------------------------------------

1.   ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION - Pan Western Energy Corporation (the "Company") was organized
     effective September 2, 1981 under the laws of the State of Oklahoma. The
     purpose of the Company is the acquisition, drilling, development,
     production and operation of oil and gas properties.

     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.

     PRINCIPLES OF CONSOLIDATION - The consolidated financial statements include
     the accounts of the Company's majority-owned partnerships, Pan Western 
     1993-A Production Program, Ltd. and Pan Western 1993-C Production Program,
     Ltd. The Company acquired the majority interest in these partnerships
     effective April 1, 1995 and the remaining partnership interests were
     acquired effective June 1, 1996. In 1996, the Company formed Lateral
     Completion Technologies, Inc. ("LCT"), a wholly owned subsidiary. LCT did
     not have any activities in 1996. All material intercompany transactions and
     balances are eliminated in consolidation.

     INVESTMENTS IN AFFILIATED PARTNERSHIPS - Investments in affiliated oil and
     gas partnerships in which the Company owns less than a majority interest
     are accounted for using the equity method, with amounts stated at original
     cost, adjusted for the Company's share of undistributed earnings or losses.
     Management regularly reviews the carrying amount of these investments for
     impairment and will adjust the carrying amount when, based on these
     reviews, they determine that such amount is not recoverable.

     OIL AND GAS PROPERTIES - The Company follows the successful efforts method
     of accounting for oil and gas producing activities. Costs to acquire
     mineral interests in oil and gas properties, to drill and equip exploratory
     wells that find proved reserves and to drill and equip development wells
     are capitalized. Costs to drill exploratory wells that do not find proved
     reserves, geological and geophysical costs, and costs of carrying and
     retaining unproved properties are expensed.

     Capitalized costs of producing oil and gas properties are depreciated and
     depleted by the unit-of-production method. Support equipment is depreciated
     over its estimated useful life.

     On the sale or retirement of a complete unit of a proved property, the cost
     and related accumulated depreciation, depletion, and amortization are
     eliminated from the property accounts, and the resultant gain or loss is
     recognized. On the retirement or sale of a partial unit of proved property,
     the cost is charged to accumulated depreciation, depletion, and
     amortization with a resulting gain or loss recognized in income.

     Valuation allowances are provided if the net capitalized cost of oil and
     gas properties exceed their estimated realizable value based on the
     undiscounted future net revenues. Unproved oil and gas properties

                                      -6-
<PAGE>
 
     are periodically assessed for impairment of value and, if necessary, a loss
     is recognized by providing an allowance.
     
     OTHER PROPERTY AND EQUIPMENT - Other property and equipment is stated at
     cost and is depreciated using accelerated methods over the estimated lives
     of the respective assets which range from 5 to 27.5 years.

     OPERATING INCOME - Operating income represents income earned by the Company
     as operator of oil and gas properties and as general partner for certain
     limited partnerships. Operating income consists primarily of administrative
     overhead fees, field supervision charges and compressor charges.

     INCOME TAXES - The Company accounts for income taxes in accordance with
     Statement of Financial Accounting Standards ("SFAS") No. 109, "Accounting
     for Income Taxes". SFAS No. 109 requires the recognition of deferred tax
     liabilities and assets for the tax effects of (a) temporary differences
     between tax bases and financial reporting bases of assets and liabilities,
     and (b) operating loss and tax credit carryforwards. The Company records a
     valuation allowance for the amount of net deferred tax assets when, in
     management's opinion, it is more likely than not that such assets will not
     be realized.

     LONG-LIVED ASSET IMPAIRMENT - Effective January 1, 1996, the Company
     adopted Statement of Financial Accounting Standards No. 121, "Accounting
     for Impairment of Long-lived Assets and for Long-lived Assets to be
     Disposed Of," ("SFAS 121"). SFAS 121 requires that long-lived assets and
     certain identifiable intangibles to be held and used by an entity be
     reviewed for impairment whenever events or changes in circumstances
     indicate that the carrying amount of an asset may not be recoverable. SFAS
     121 also requires that assets to be disposed of be reported at the lower of
     carrying amount or fair value less cost to sell. The adoption of SFAS 121
     did not have a significant effect on the Company's consolidated financial
     statements.

     STOCK-BASED COMPENSATION - In October 1995, the Financial Accounting
     Standards Board issued Statement of Financial Accounting Standards No. 123
     ("SFAS 123"), "Accounting for Stock-Based Compensation." SFAS 123
     establishes a fair value method and disclosure standards for stock-based
     employee compensation arrangements, such as stock purchase plans and stock
     options. It also applies to transactions in which an entity issues its
     equity instruments to acquire goods or services from non-employees,
     requiring that such transactions be accounted for based on fair value. As
     allowed by SFAS 123, the Company will continue to follow the provisions of
     Accounting Principles Board Opinion No. 25 for its stock-based employee

     FAIR VALUE OF FINANCIAL INSTRUMENTS - Statement of Financial Accounting
     Standards No. 107 "Disclosures about Fair Value of Financial Instruments"
     requires disclosure regarding the fair value of financial instruments for
     which it is practical to estimate that value. For accounts receivable and
     accounts payable, the carrying amount approximates fair value because of
     the short maturity of those instruments. The fair value of the Company's
     long-term debt is estimated to approximate carrying value based on the
     borrowing rates currently available to the Company for bank loans with
     similar terms and maturities.

     EARNINGS (LOSS) PER SHARE - Loss per share is calculated based on the
     weighted average common shares outstanding retroactively adjusted for the
     four-for-one stock split effected in the form of a stock dividend declared
     by the Company on February 18, 1997 (see Note 10). Outstanding stock
     options and warrants are not included in the computation since their effect
     on loss per share is antidilutive.

     RESTRICTED CASH - Restricted cash consists of a certificate of deposit that
     serves as collateral on a line of credit with a bank.

 2.  PARTNERSHIP ACQUISITIONS

     In 1995 and 1996, the company acquired several entities. These acquisitions
     were accounted for using the purchase method and the purchase price was
     allocated to assets acquired, primarily oil and gas properties, and
     liabilities assumed based on their estimated fair values. The results of
     operations of the entities have been included in the Company's consolidated
     financial statements subsequent to the dates of acquisition.

     Effective April 1, 1995, the Company acquired all of the limited partners'
     interests in several oil and gas limited partnerships for which it was the
     general partner and liquidated the partnerships. The partnership interests
     acquired were: the Pan Western 1991-A Production Program, Ltd.; the Pan
     Western 1991-B Production Program, Ltd.; the Pan Western 1992-B Production
     Program, Ltd.; and the Pan Western 1993-B Production Program, Ltd.

     In addition, effective April 1, 1995, the Company acquired 96% of the
     limited partners' interest in the Pan Western 1993-A Production Program,
     Ltd. ("1993-A"), and approximately 74% of the limited partners' interest in
     the Pan Western 1993-C Production Program, Ltd. ("1993-C"). The Company is
     the general partner in these partnerships.

     The consideration paid by the Company for these limited partnership
     interests consisted of 1,349,900 shares of the Company's common stock
     (valued at approximately $1,267,000 based on the estimated value of the
     partnerships' oil and gas reserves) and $8,392 in cash, and included
     approximately $611,000 in partnerships' debt.

     Effective May 31, 1996, the Company acquired the remaining interests in the
     1993-A and 1993-C partnerships in exchange for 46,320 shares of the
     Company's common stock (valued at approximately $59,000 based on estimated
     value of the partnerships' oil and gas reserves).

     On December 1, 1995, the Company purchased the remaining 50% partnership
     interest in South Boulder Associates, Ltd. and liquidated the partnership.
     The Company previously owned a 50% interest in this partnership and was the
     general partner. South Boulder Associates, Ltd. owns and manages the office
     building known as "Boulder on the Park", located at 1850 South Boulder
     Avenue, Tulsa, Oklahoma. The purchase price paid for the remaining interest
     was $50,000 in cash, and included approximately $168,000 in partnership
     debt.

     The following unaudited pro-forma information combines the results of
     operations of the Company and the various partnerships discussed above, as
     if the acquisitions had taken place on January 1, 1995, after giving effect
     to the effect on depreciation and depletion based upon purchase amounts
     allocated to producing oil and gas properties and other property.

 3.  INVESTMENTS IN AFFILIATED PARTNERSHIPS

     The Company is general partner in Pan Western 1986 Drilling Program, Ltd.
     ("1986 Program"), Pan Western 1987 Production Program, Ltd. ("1987
     Program") and Pan Western 1989-A Production Program Joint Venture ("1989-
     A"), whose purpose is the acquisition, drilling, development, production,
     marketing and operation of oil and gas leases. As general partner, the
     Company is entitled to 18.57% and 15% of the current earnings or losses for
     the 1986 and 1987 Programs, respectively, and is also entitled to a "back-
     in" interest upon payout. The Company is entitled to a "back-in" interest
     only on 1989-A.

     The summary information below does not include information on the 1989-A
     since the Company has never received a back-in interest.

     Summary financial information for these partnerships as of and for the
     years ended December 31, 1996 and 1995 follows:

</TABLE> 

     During 1989, the Company's share of losses exceeded the carrying value of
     its investment in the 1986 and 1987 Programs, and the equity method of
     accounting was discontinued with no additional losses recorded by the
     Company. However, during 1995, the total partners' capital of the 1986
     Program became a deficit. Accordingly, as general partner, the Company
     recorded additional losses under the equity method to the extent of the
     1986 Programs' capital deficit. During 1996, the total partners' capital of
     the 1986 Program became positive, and the additional losses previously
     recorded by the Company were reversed. The Company's share of unrecorded
     losses for the 1986 and 1987 Programs was approximately $31,255 and $25,600
     at December 31, 1996 and 1995, respectively.

     At December 31, 1996, the Company had net operating loss carryforwards of
     approximately $561,000 which will expire during the years 2009 through
     2011.

     The difference between the Company's effective tax rate and the statutory
     Federal income tax rate results from the valuation allowance established
     for net operating loss carryforwards, the effect of state income taxes,
     graduated Federal income tax rates, and nondeductible travel and
     entertainment expenses.

 7.  RELATED PARTIES

     Until December 1, 1995, the Company leased office space under an operating
     lease from a partnership in which it had a 50% interest. Effective December
     1, 1995, the Company acquired the remaining 50% interest in the partnership
     (see Note 2). During 1995, $25,800 was paid to the partnership as rent.

     Through August 1995, the Company sold gas produced from certain wells it
     operates to a gas marketing company owned by the president of the Company.
     Such sales for the years ended December 31, 1995 were approximately
     $89,000. The gas marketing company collected a 3% commission on the resale
     of

                                      -13-
<PAGE>
 
     such gas, which was utilized to pay income and other taxes of the gas
     marketing company. No funds were paid to the president of the Company in
     connection with these transactions.

     In 1995, the Company began paying a fee to the Company president based on
     the terms of a "Guaranty Fee Agreement". Under the agreement he receives an
     annual fee for guaranteeing the Company debt equal to the greater of
     $15,000 or 3% of the guaranteed debt. During 1996 and 1995, this fee was
     approximately $76,000 and $30,000, respectively.

     The Company incurs fees for accounting and consulting services provided by
     a firm in which a board member of the Company is a partner. Such amounts
     incurred during 1996 and 1995 were $39,943 and $34,476, respectively.
     During 1996, the Company issued 35,700 shares of its common stock to this
     firm for services rendered. The value assigned to this stock, $49,980, was
     based on billings received from the firm.

     During 1995 the Company paid $20,100 and issued 12,205 shares of Company
     stock to a company for services related to the conversion of limited
     partnership interests to common stock interests (see Note 2). The chief
     executive officer of this Company is a member of the Company's board of
     directors.

     Pursuant to an agreement signed in February 1996, a director of the Company
     will provide evaluation and reservoir engineering services to the Company
     in exchange for an amount equal to the net of a percentage of the net
     revenue interest of a certain well and a percentage of the lease operating
     expenses attributable to the same well.

8.   STOCK OPTION PLANS

     The Company established the Pan Western Energy Corporation 1992 Directors
     Stock Option Plan (the "Directors Plan") under which non-employee directors
     of the Company may be granted options to purchase shares of common stock.
     The plan provides that the option price shall be the fair value of the
     common stock at the date granted and that options are exercisable for 10
     years and 30 days from date granted. At December 31, 1996 and 1995, 135,000
     and 127,500 shares were available for grant of stock options and options
     covering 15,000 and 22,500 shares which were granted in July 1993 at $1.30
     per share were exercisable at December 31, 1996 and 1995, respectively.

     On January 21, 1997, the Board of Directors approved the grant of options
     to acquire 50,000 shares of the Company's common stock at $1.40 per share
     under the Directors Plan.

     The 1992 Employee Stock Option Plan (the "Employee Plan") has also been
     adopted by the Company's board of directors and approved by the
     shareholders. There are 100,000 options available for grant under this Plan
     and no options have been granted under the Plan.

     Outstanding options granted under both the Directors and Employee Stock
     Option Plans are terminated if the option holder ceases to be an employee
     or director of the Company.

     In July 1993, the Board of Directors approved the grant of options to the
     Company's president to acquire 7,500 shares of common stock at $1.30 per
     share (the estimated fair value at the date granted). These options are
     exercisable at any time up to ten years from date of grant. On January 21,
     1997, the Board of Directors approved the grant of options to certain
     executive officers to acquire 570,000 shares of the Company's common stock
     at $1.40 per share. These options vest at 40% on date of grant; 30% one
     year from date of grant; and the remaining 30% two years from date of
     grant. These options were not granted pursuant to the existing Employee
     Plan.

9.   STOCK PURCHASE WARRANTS

     In March 1996, Pangloss International, S.A. ("Pangloss") acquired 87,500
     shares of the Company's common stock for $1.20 per share, and concurrently
     was granted warrants to purchase 125,000 shares at $1.60 per share.
     Pangloss was granted additional warrants in July 1996 to purchase 100,000
     shares of the Company's common stock at $1.20 per share. These warrants
     were issued in connection with a $105,000 loan from Pangloss that was
     repaid in December 1996. 

     All of the warrants issued to Pangloss are exercisable at any time prior to
     April 15, 2001.

10.  STOCKHOLDERS' EQUITY

     On June 20, 1996, the Company's stockholders approved amendments to the
     Certificate of Incorporation to increase the authorized common stock to
     25,000,000 shares, and to establish a class of preferred stock. The Board
     of Directors was authorized to fix the rights and terms applicable to the
     preferred stock prior to issuance.

     On February 18, 1997, the Board of Directors approved a four-for-one stock
     split effected in the form of a stock dividend. The record date for the
     dividend is April 1, 1997. Common share, per share data, and stockholders'
     equity amounts in the accompanying consolidated financial statements and
     footnotes (unless otherwise indicated) have been retroactively adjusted to
     reflect this stock split.

11.  COMMITMENTS AND CONTINGENCIES

     The Company has executed employment agreements with certain executive
     officers which expire on the later of specified dates in the year 2000 or
     the date to which the agreement has been extended; or, in the case of the
     Company's president, as long as the president guarantees the Company's
     debt. Under the terms of these agreements, the executives will receive
     annual salaries aggregating $238,000. In addition, the Company's president
     will receive incentive compensation equal to 10% of the Company's annual
     pre-tax income in excess of $150,000. The other executive officers will
     share in a bonus pool equal to 10% of the Company's net income in excess of
     $100,000. In the event of the executives' termination without just cause,
     as defined in the agreements, the Company must pay them these amounts for
     the remaining term of the agreements.

     The Company has received billings of approximately $178,000 from a law firm
     which represented the Company in a lawsuit filed as plaintiff. The Company
     eventually lost the suit and is disputing the amount of the law firm's
     billing. The Company has not recorded a liability for approximately $88,000
     of this billed amount.

12.  SIGNIFICANT CUSTOMERS

     There were four purchasers in 1996 which represented approximately 18%,
     16%, 15% and 11% of the Company's total revenues. There were three
     purchasers in 1995 which represented approximately 37%, 34% and 17% of the
     Company's total revenues.

13.  BUSINESS DEVELOPMENTS

     During 1996, the Company acquired a license from Amoco Corporation to
     utilize their patented short radius curve drilling technology. The patent
     was originally issued in 1993. The Company paid $40,000 for the license and
     will pay a scheduled royalty for its use in the future. The Company plans
     to use the 

                                      -15-
<PAGE>
 
     technology to develop reserves currently owned by the Company.
     In addition, the Company intends to provide the technology to other
     operators through a wholly owned subsidiary, Lateral Completion
     Technologies, Inc., and develop reserves for other operators in return for
     working and net revenue interests in those reserves. The Company is
     currently pursuing financing alternatives to provide the funds needed to
     fund the capital expenditures and initial operating costs of Lateral
     Completion Technologies, Inc. These alternatives include a private
     placement of debt or equity or a combination thereof.

14.  SALE OF COMMON STOCK

     The Company is currently attempting to sell 15,000 shares of its common
     stock at $10 per share (75,000 shares at $2 per share after giving effect
     to the stock split discussed in Note 10) through an offering pursuant to
     Regulation D and Rule 504 of the Securities Act of 1933. Purchases of
     common stock under this offering will be limited to 100 shares per
     individual. The Company's sole purpose for this offering is to increase the
     shareholder base to at least 300 in order to meet one of the requirements
     imposed by NASDAQ to qualify for trading on the NASDAQ Small Cap Market.


15.  REGISTRATION OF COMMON STOCK

     The Company is in the process of preparing a Form-10-SB to be filed with
     the Securities and Exchange Commission on or about March 15, 1997. The
     purpose of this filing is to register all issued and outstanding shares of
     the Company's common stock.

16.  SUPPLEMENTAL INFORMATION ABOUT OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED)

     The following information summarizes the Company's net proved reserves of
     oil and gas and the present values thereof for the years ended December 31,
     1996 and 1995. The information presented for 1996 and 1995 is based upon
     estimates prepared by Sycamore Resources, LLC, which was engaged to perform
     an evaluation of the present value of estimated future net cash flows
     before income tax (discounted at 10%). The information was prepared in
     accordance with Statement of Financial Accounting Standards No. 69.

     Prices of crude oil, condensate, and gas were those prices in effect at the
     respective date. Estimated future production costs, which include lease
     operating costs and severance taxes (estimated assuming existing economic
     conditions will continue over the lives of the individual leases, with no
     adjustment for inflation), have been deducted in arriving at the estimated
     future net revenues. The present value amounts should not necessarily be
     equated with fair market value of the Company's oil and gas reserves. All
     reserves are located in the United States.

     The reliability of any reserve estimate is a function of the quality of
     available information and of engineering interpretation and judgment. These
     reserves should be accepted with the understanding that subsequent drilling
     activities or additional information might require their revision.

Officers or have a financial interest, shall be void or voidable solely for this
reason, or solely because the Directors or Officers are present at or
participate in the meeting of the Board or Committee thereof which authorizes
the contract or transaction, or solely because the Directors or Officers or
their votes are counted for such purpose.  Common or interested Directors may be
counted in determining the presence of a quorum at a meeting of the Board of
Directors or a committee thereof which authorizes the contract or transaction.

     TENTH:  To the extent and in the manner provided by the laws of the State
of Oklahoma, the Board of Directors is expressly authorized to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding whether civil,
criminal, administrative or investigative, by reason of the fact that such
person is or was a Director, Officer, employee or agent of the Corporation or is
or was serving at the request of the Corporation as a Director, Officer,
employee or agent of another Corporation, partnership, joint venture, trust or
other enterprise against expenses, including attorneys' fees, judgments, fines
and amounts paid in settlement actually and reasonably incurred.

     ELEVENTH:  No director of the Corporation shall be personally liable to the

Neither the amendment nor repeal of this Article 11, nor the adoption of any
provision of the Corporation's Certificate of Incorporation inconsistent with
this Article 11, shall eliminate or reduce the effect of this Article 11 in
respect of any matter occurring, or any cause of action, suit or claim that, but
for this Article 11, would accrue or arise, prior to such amendment, repeal or
adoption of an inconsistent provision.

any other fiscal year of the Corporation in which Anderson is not employed
hereunder for the entire fiscal year.  The Corporation's fiscal year is the
calendar year.  No change in the Corporation's fiscal year will result in the
reduction of any amounts payable under this subsection.  For purposes of this
Section 3 (b), the Corporation's pre-tax net profit in any year shall be that
shown on the Corporation's annual audited financial statements. This definition
is for the sole purpose of determining Anderson's annual incentive compensation
and shall have no effect on the Corporation's financial reporting. Anything to
the contrary set forth herein notwithstanding, this Section 3 (b) shall not be
construed to create any liability or obligation of Anderson to the Corporation
with regard to any period during the term hereof in which the Corporation's pre-
tax net profit fails to exceed the amounts set forth above.

     4.  Covenant Not to Compete.  Anderson covenants and agrees that, during
         -----------------------                                             
the term of his employment and for a period of two (2) years thereafter, he will
not, directly or indirectly, engage in or become financially or otherwise
interested in any business in which the Corporation (or any affiliate) is now
engaged or in which it becomes engaged at any time during the term of Anderson's
employment with the Corporation relating to the primary business of the
Corporation. The area covered by this covenant includes the continental United
States. This covenant extends to Anderson, whether
<PAGE>
 
as a principal, agent, manager, employee, lessor, consultant, partner,
shareholder, director, officer or otherwise. This covenant does not extend to
Anderson's ownership of less than two percent (2%) of the voting interests in a
publicly held corporation. Anderson expressly acknowledges that his execution of
this covenant not to compete is a material factor in the Corporation's execution
of this Agreement; that its specific terms were bargained for; that this
covenant not to compete is of material import to the Corporation as the business
in which the Corporation is engaged is highly competitive; and that the covenant
not to compete does not constitute an unreasonable restriction on Anderson.

     5.  Disclosure of Information.  It is agreed that any and all improvements,
         -------------------------                                              
discoveries or results of research, whether patentable or not, which are made,
discovered or invented by Anderson, any other employee, contractor, or
consultant to the Corporation, which relate in any manner to any products,
equipment, work or other business activity of the Corporation or any affiliated
corporation during the term of Anderson's employment, shall be and become the
exclusive property of the Corporation.  Anderson expressly acknowledges that the
list of the Corporation's customers, its trade secrets and other information
pertaining to the patent rights, designs, methods, systems, improvements,
proprietary information, sales data, trademarks, products, and business affairs
of the Corporation, as the same may exist from time to time, are the sole
property of the Corporation (or its affiliated corporations as the case may be),
are strictly confidential, and shall be held in trust solely for the benefit and
use of the Corporation (or its affiliated corporations as the case may be). All
knowledge and information which Anderson may acquire by, from or through the
Corporation during the course of rendering services under this Agreement, or
from the employees or consultants to the Corporation (or of any affiliated
corporation as the case may be), with respect to any such information as is
specified above, and other confidential matters shall for all purposes, be
regarded as strictly confidential and held in trust and solely for the benefit
and use of the Corporation (or its affiliated corporations as the case may be).
Anderson covenants and agrees that he shall not, during the term of this
Agreement, or at any time after the termination hereof, disclose any such
information to any person, firm, corporation, association or other entity or
group of persons, for any reason or purpose whatsoever; provided, however, that
the covenants contained in this Section 5 shall not prevent Anderson from making
such disclosures (i) as may be necessary in the performance of the services
hereunder, (ii) as may be necessary to comply with legal process or
governmental order, or (iii) to the extent such information is already in the
public domain at the date of such disclosure.

     6.  Termination of Employment.
         ------------------------- 

     (a) Termination for Just Cause.  For just cause due to the fault of
         --------------------------                                     
Anderson, the Corporation may terminate Anderson's employment at any time upon
ten (10) days written notice to Anderson and the Corporation shall be obligated
to pay Anderson the compensation 
<PAGE>
 
under Section 3 due him only up to the date of termination, including any
accrued employee benefits and/or vacation pay. As used in this Agreement, the
term "just cause" shall mean (i) Anderson shall engage in willful and material
misconduct in the performance or nonperformance of this Agreement; and (ii)
Anderson shall commit actual fraud or a felony criminal act on or after the date
of execution hereof, and any such act shall have been determined by the Board of
Directors to be materially harmful to the Corporation. Said Board action shall
only be taken after reasonable notice to Anderson and after having provided
Anderson an opportunity to present his position. Anderson's commission of fraud
or a felony criminal act shall be determined by a court of competent
jurisdiction or admitted by Anderson. Termination under this subsection 6(a)
shall result in the termination for future periods of all compensation otherwise
payable to Anderson under Section 3 (a), and shall render null and void ab
                                                                        --
initio the Corporation's obligation to pay the incentive compensation specified
- ------
in Section 3 (b). Anderson's termination under this Section 6(a) shall not
affect Anderson's obligations under Sections 4 or 5 hereof.

     (b) Termination Without Just Cause.  The Corporation may terminate
         ------------------------------                                
Anderson's employment without just cause, but in such event the Corporation
shall be obligated to pay to Anderson the compensation otherwise payable under
Section 3(a) for the remainder of the term of his employment as determined in
Section 2, including any accrued employee benefits and/or vacation pay. Any
amount of such Section 3(a) compensation in a gross amount before withholding
taxes up to the greater of One Hundred Thousand Dollars ($100,000) or the amount
of Anderson's combined federal and estate income taxes, if any, resulting from
the Corporation's obligation to pay such remaining Section 3(a) compensation
which are due in the year of termination (or not later than the due date for the
filing of Anderson's individual income tax returns for such year), shall be paid
in cash thirty (30) days following the date of Anderson's termination. The
amount, if any, of Anderson's Section 3(a) compensation exceeding such amount
shall be paid in cash in two equal annual installments, on the first and second
anniversaries of Anderson's termination. No interest shall accrue on such
payments, and the Corporation shall deduct therefrom all normal employee
withholding taxes. If the Corporation terminates Anderson's employment under
this Section 6(b), the incentive compensation otherwise due to Anderson under
Section 3(b) shall be payable at the time(s) and in the form and manner set
forth in Section 3(b). Termination of Anderson's employment under this
subsection 6(b) shall not affect Anderson's obligations under Sections 4 or 5
hereof. The foregoing notwithstanding, Anderson may, within ninety (90) days
following the termination of his employment under this Section 3 (b), notify the
Corporation in accordance with Section 8(b) that he has determined to take
actions which would otherwise violate Section 4 hereof. In such case, and
subject to the following conditions, Anderson shall be relieved of his
obligations under Section 4 hereof. In order to be relieved of such Section 4
obligations, Anderson agrees that his compensation under Sections 3(a) and 3(b)
shall terminate as of the date of his termination, and
<PAGE>
 
Anderson shall forfeit and return to the Corporation any Section 3(a)
compensation and evidences of indebtedness of the Corporation therefor
applicable to periods after his termination; Anderson's Section 3(b)
compensation shall accrue only to the date of his termination and it shall be
paid as and when it would otherwise be paid under Section 3(b). Anderson may be
terminated under this Section 6(b) only by unanimous vote of the Board of
Directors of the Corporation, including Anderson if he is a director of the
Corporation at the time the vote is taken. The Corporation shall have the right
to prepay all or any part of any payments provided for in this Section 6(b) at
any time without penalty.

     (c) Termination by Anderson.  Anderson may terminate his employment at any
         -----------------------                                               
time on thirty (30) days prior written notice to the Corporation, end in such
event, the Corporation shall be obligated to pay Anderson his Section 3(a)
compensation only up to the date of termination, including any accrued employee
benefits and/or vacation pay.  If Anderson dies during the term of this
Agreement, his compensation shall continue only to the date of his death.  If he
becomes disabled such that he cannot perform his principal duties hereunder for
a period of longer than three (3) months, the Corporation may terminate his
employment after the end of such three (3) month period and in such event
Anderson's compensation shall terminate at such date.  Termination under this
subsection 6(c) shall not affect Anderson's obligations under Sections 4 or 5.
If Anderson's employment terminates under this Section 6(c), the incentive
compensation otherwise due to Anderson under Section 3(b) shall accrue to the
date of termination of his employment under this Section 6(c).  The Corporation
shall have the right to prepay all or any part of any payments provided for in
this Section 6(c) at any time without penalty.

     7.  Remedy for Breach.

                             GUARANTY FEE AGREEMENT
                             ----------------------


     THIS GUARANTY FEE AGREEMENT ("Agreement") is made as of November 1, 1995,
by and PAN WESTERN ENERGY CORPORATION, an Oklahoma corporation (the
"Corporation"), and SIDNEY L. ANDERSON, a resident of Tulsa, Oklahoma
("Anderson"), and is made with reference to the following:

     A.   Anderson is the sole guarantor of the Corporation's indebtedness and
obligations to State Bank and Trust Company, N.A., Tulsa, Oklahoma, First Bank
and Trust, Wagoner, Oklahoma, and other creditors of the Corporation.

     B.   The Corporation has not previously paid Anderson an annual guaranty
fee.  In the parties' judgment, the Corporation should pay to Anderson an annual
guaranty fee so long as Anderson or any member of his immediate family is
required to guaranty the Corporation's obligations to any creditors of the
Corporation, including but not limited to the creditors named above.

     NOW, THEREFORE, in consideration of the mutual promises, covenants and
agreements set forth in the Agreement, the parties agree as follows:

     1.   Guaranty Fee.  So long as Anderson is required, as a condition to the
          ------------                                                         
granting of credit or the making of loans to the Corporation, to guaranty any
obligation or indebtedness of the Corporation to any creditor of the
Corporation, the corporation shall pay to Anderson, annually, a guaranty fee
equal to the greater of Fifteen Thousand Dollars ($15,000) or three percent (3%)
of the amount guarantied by him.  For the purposes of this Agreement, the amount
guaranteed by Anderson shall include, without limitation, any undrawn amounts
under lines of credit extended to the Corporation and any accrued interest under
any outstanding loans to the extent covered by the agreements signed by Anderson
guarantying such obligations or indebtedness.  The guaranty fed shall be paid in
cash in semi-annual installments on June 30 and December 31 of each year in
which Anderson's guaranty or guarantees are outstanding.

     2.   Guaranty Fee for Amounts Guarantied by Anderson's Family Members. If
          ----------------------------------------------------------------
any member of Anderson's immediate family, including his spouse or children, in
any, is required by any creditor of the Corporation to separately guaranty any
amounts owed to said creditor, such amounts shall be deemed to be guarantied by
Anderson for the purposes of this Agreement and a guaranty fee shall be paid to
Anderson in a like amount as set forth in Section 1 hereof if he is living at
the time the family member's guaranty is outstanding. If he is not living at the
time, the guaranty fee shall be paid to his family member. The foregoing
notwithstanding, if Anderson and his family member(s) are guarantying the same
indebtedness at the same time pursuant to guaranty agreements which are
effective at the same time and Anderson is collecting a guaranty fee pursuant to
Section l, then only one guaranty fee shall be paid in respect of
<PAGE>
 
said indebtedness. In such event, the guaranty fee shall be calculated based on
the highest amount guarantied. For example, if a creditor extends $1 million
there f,- and his spouse separately guarantees $500,000 of such obligations, the
guaranty fee payable to Anderson shall be based on $1 million.

     3.   Miscellaneous.

     4.   Covenant Not to Compete.  Livingston covenants and agrees that, during

Livingston's employment with the Corporation relating to the primary business of
the Corporation.  The area covered by this covenant includes the Oklahoma and
its adjoining states.  This covenant extends to Livingston, whether as a
principal, agent, manager, employee, lessor, consultant, partner, shareholder,
director, officer or otherwise. This covenant does not extend to Livingston's
ownership of less than two percent (2%) of the voting interests in a publicly
held corporation.  Livingston expressly acknowledges that his execution of this
covenant not to compete is a material factor in the Corporation's execution of
this Agreement; that its specific terms were bargained for; that this covenant

the Corporation is engaged is highly competitive; and that the covenant not to
compete does not constitute an unreasonable restriction on Livingston. Excluded
from this Paragraph 4. are working interests, royalty interests and overriding
royalty interests owned by Livingston prior to the effective date of this
Agreement.  Further, this Paragraph 4. will not apply to any working interests,
royalty interests or overriding royalty interests conveyed to Livingston as

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

consultant to the Corporation, which relate in any manner to any products,
equipment, work or oth-
<PAGE>
 
er business activity of the Corporation or any affiliated corporation during the
term of Livingston's employment, shall be and become the exclusive property of
the Corporation. Further, Livingston expressly acknowledges that the list of the
Corporation's customers, its trade secrets and other information pertaining to
the patent rights, designs, methods, systems, improvements, proprietary
information, sales data, trademarks, products, and business affairs of the
Corporation, as the same may exist from time to time, are the sole property of
the Corporation (or its affiliated corporations as the case may be), are
strictly confidential, and shall be held in trust solely for the benefit and use
of the Corporation (or its affiliated corporations as the case may be). All
knowledge and information which Livingston may acquire by, from or through the
Corporation during the course of rendering services under this Agreement, or
from the employees or consultants to the Corporation (or of any affiliated
corporation as the case may be), with respect to any such information as is
specified above, and other confidential matters shall for all purposes, be
regarded as strictly confidential and held in trust and solely for the benefit
and use of the Corporation (or its affiliated corporations as the case may be).
Livingston covenants and agrees that he shall not, during the term of this
Agreement, or at any time after the termination hereof, disclose any such
information to any person, firm, corporation, association or other entity or
group of persons, for any reason or purpose whatsoever; provided, however, that
the covenants contained in this Section 5 shall not prevent Livingston from
making such disclosures (i) as may be necessary in the performance of the
services hereunder, (ii) as may be necessary to comply with legal process or
governmental order, or (iii) to the extent such information is already in the
public domain at the date of such disclosure.

     6.   Termination of Employment.
          ------------------------- 

     (a)  Termination for Just Cause.  For just cause due to the fault of
          --------------------------                                     
Livingston, the Corporation may terminate Livingston's employment at any time
upon ten (10) days written notice to Livingston and the Corporation shall be
obligated to pay Livingston the compensation under Section 3 due him only up to
the date of termination, including any accrued employee benefits and/or vacation
pay.  As used in this Agreement, the term "just cause" shall mean (i) Livingston
shall engage in willful and material misconduct in the performance or
nonperformance of this Agreement; and (ii) Livingston shall commit actual fraud
or a felony criminal act on or after the date of execution hereof.  Such action
shall only be taken after reasonable notice to Livingston and after having
provided Livingston an opportunity to present his position.  Livingston's
commission of fraud or a felony criminal act shall be determined by a court of
competent jurisdiction or admitted by Livingston.  Termination under this
subsection 6(a) shall result in the termination for future periods of all
compensation otherwise payable to Livingston under Section 3 (a), and shall
render null and void ab initio the Corporation's obligation to pay the incentive
                     -- ------
compensation specified in Section 3(b).  Livingston's termination under this
Section 6(a) shall not affect Livingston's obligations under Sec-
<PAGE>
 
tions 4 or 5 hereof.

     (b)  Termination Without Just Cause.  The Corporation may terminate
          ------------------------------                                
Livingston's employment without just cause, but in such event the Corporation
shall be obligated to pay to Livingston the compensation otherwise payable under
Section 3 (a) for the remainder of the term of his employment as determined in
Section 2, including any accrued employee benefits and/or vacation pay.  Any
amount of such Section 3 (a) compensation in a gross amount before withholding
taxes up to the greater of One Hundred Thousand Dollars ($100,000) or the amount
of Livingston's combined federal and state income taxes, if any, resulting from
the Corporation's obligation to pay such remaining Section 3(a) compensation
which are due in the year of termination (or not later than the due date for the
filing of Livingston's individual income tax returns for such year), shall be
paid in cash thirty (30) days following the date of Livingston's termination.
The amount, if any, of Livingston's Section 3(a) compensation exceeding such
amount shall be paid in cash in two equal annual installments, on the first and
second anniversaries of Livingston's termination.  No interest shall accrue on
such payments, and the Corporation shall deduct there from all normal employee
withholding taxes.  If the Corporation terminates Livingston's employment under
this Section 6(b), the incentive compensation otherwise due to Livingston, if
any, under Section 3(b) shall be payable at the time(s) and in the form and
manner set forth in Section 3 (b). Termination of Livingston's employment under
this subsection 6(b) shall not affect Livingston's obligations under Sections 4
or 5 hereof.  The foregoing notwithstanding, Livingston may, within ninety (90)
days following the termination of his employment under this Section 3 (b),
notify the Corporation in accordance with Section 8(b) that he has determined to
take actions which would otherwise violate Section 4 hereof.  In such case, and
subject to the following conditions, Livingston shall be relieved of his
obligations under Section 4 hereof.  In order to be relieved of such Section 4
obligations, Livingston agrees that his compensation under Sections 3(a) and
3(b) shall terminate as of the date of his termination, and Livingston shall
forfeit and return to the Corporation any Section 3(a) compensation and
evidences of indebtedness of the Corporation there for applicable to periods
after his termination; Livingston's Section 3(b) compensation shall accrue only
to the date of his termination and it shall be paid as and when it would
otherwise be paid under Section 3(b).  Livingston may be terminated under this
Section 6(b) only by a seventy five percent (75%) vote of the Board of Directors
of the Corporation, including Livingston's if he is a director of the
Corporation at the time the vote is taken. The Corporation shall have the right
to prepay all or any part of any payments provided for in this Section 6(b) at
any time without penalty.

     (c)  Termination by Livingston.  Livingston may terminate his employment at
          -------------------------                                             
any time on thirty (30) days prior written notice to the Corporation, and in
such event, the Corporation shall be obligated to pay Livingston his Section
3(a) compensation only up to the date of termination, including any accrued
employee benefits 
<PAGE>
 
and/or vacation pay. If Livingston dies during the term of this Agreement, This
compensation shall continue only to the date of his death. If he becomes
disabled such that he cannot perform his principal duties hereunder for a period
of longer than three (3) months, the Corporation may terminate his employment
after the end of such three (3) month period and in such event Livingston's
compensation shall terminate at such date. Termination under this subsection
6(c) shall not affect Livingston's obligations under Sections 4 or 5. If
Livingston's employment terminates under this Section 6(c), the incentive
compensation otherwise due to Livingston under Section 3(b) shall accrue to the
date of termination of his employment under this Section 6(c). The Corporation
shall have the right to prepay all or any part of any payments provided for in
this Section 6(c) at any time without penalty.

     7.   Remedy for Breach.

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

receive annually vacation time as specified in the Corporation's Personnel
Manual, which may be carried over one year.  Salary shall be payable in
installments twice monthly.

     (b) Annual Incentive Compensation.  As annual incentive compensation, the
         -----------------------------                                        
Corporation will establish a bonus pool equal to ten percent (10%) of the
Corporation's net income in excess of $100,000 as reflected by the Corporation's
annual audited financial statements.  This sum shall be paid to those
individuals participating in said bonus pool as incentive compensation within
forty five (45) days from the date the annual audited financial statements are
delivered to the Corporation's Board of Directors.  The amount to be paid to
each individual participant shall be determined by the Corporation's Board of
Directors based upon recommendations made to it by the Corporation's Chief
Executive Officer.  Kemendo shall be eligible to participate in this bonus pool.
As further incentive compensation, Kemendo shall be eligible to participate in

     4.  Covenant Not to Compete.  Kemendo covenants and agrees that, during the
         -----------------------                                                
term of his employment and for a period of two (2) years thereafter, he will
not, directly or indirectly, engage in or become financially or otherwise
interested in any business in which the Corporation (or any affiliate) is now
engaged or in which it becomes engaged at any time during the term of Kemendo's
employment with the Corporation relating to the primary business of the
Corporation.  The area covered by this covenant includes the Oklahoma and its
adjoining states.  This covenant extends to Kemendo, whether as a principal,
agent, manager, employee, lessor, consultant, partner, shareholder, director,
officer or otherwise.  This covenant does not extend to Kemendo's ownership of
less than two percent (2%) of the voting interests in a publicly held-
corporation.  Kemendo expressly acknowledges that his execution of this covenant
not to compete is a material factor in the Corporation's execution of this
Agreement; that its specific terms were bargained for; that this covenant not to
compete is of material import to the Corporation as the business in which the
Corporation is engaged is highly competitive; and that the covenant not to
compete does not constitute an unreasonable restriction on Kemendo.

     5.  Disclosure of Information.  It is agreed that any and all improvements,
         -------------------------                                              
discoveries or results of research, whether patentable or not, which are made,
discovered or invented by Kemendo, any other employee, contractor, or consultant
to the Corporation, which relate in any manner to any products, equipment, work
or other business activity of the Corporation or any affiliated corporation
during the term of Kemendo's employment, shall be and become the exclusive
property of the Corporation. Further, Kemendo expressly acknowledges that the
list of the Corporation's customers, its trade secrets and other information
pertaining to the patent
<PAGE>
 
rights, designs, methods, systems, improvements, proprietary information, sales
data, trademarks, products, and business affairs of the Corporation, as the same
may exist from time to time, are the sole property of the Corporation (or its
affiliated corporations as the case may be), are strictly confidential, and
shall be held in trust solely for the benefit and use of the Corporation (or its
affiliated corporations as the case may be). All knowledge and information which
Kemendo may acquire by, from or through the Corporation during the course of
rendering services under this Agreement, or from the employees or consultants to
the Corporation (or of any affiliated corporation as the case may be), with
respect to any such information as is specified above, and other confidential
matters shall for all purposes, be regarded as strictly confidential and held in
trust and solely for the benefit and use of the Corporation (or its affiliated
corporations as the case may be). Kemendo covenants and agrees that he shall
not, during the term of this Agreement, or at any time after the termination
hereof, disclose any such information to any person, firm, corporation,
association or other entity or group of persons, for any reason or purpose
whatsoever; provided, however, that the covenants contained in this Section 5
shall not prevent Kemendo from making such disclosures (i) as may be necessary
in the performance of the services hereunder, (ii) as may be necessary to comply
with legal process or governmental order, or (iii) to the extent such
information is al- ready in the public domain at the date of such disclosure.

     6.  Termination of Employment.
         ------------------------- 

     (a) Termination for Just Cause.  For just cause due to the fault of
         --------------------------                                     
Kemendo, the Corporation may terminate Kemendo's employment at any time upon ten
(10) days written notice to Kemendo and the Corporation shall be obligated to
pay Kemendo the compensation under Section 3 due him only up to the date of
termination, including any accrued employee benefits and/or vacation pay.  As
used in this Agreement, the term "just cause" shall mean (i) Kemendo shall
engage in willful and material misconduct in the performance or nonperformance
of this Agreement; and (ii) Kemendo shall commit actual fraud or a felony
criminal act on or after the date of execution hereof.  Such action shall only
be taken after reasonable notice to Kemendo and after having provided Kemendo an
opportunity to present his position.  Kemendo's commission of fraud or a felony
criminal act shall be determined by a court of competent jurisdiction or
admitted by Kemendo.  Termination under this subsection 6(a) shall result in the
termination for future periods of all compensation otherwise payable to Kemendo
under Section 3(a), and shall render null and void ab initio the Corporation's
                                                   -- ------                  
obligation to pay the incentive compensation specified in Section 3(b).
Kemendo's termination under this Section 6(a) shall not affect Kemendo's
obligations under Sections 4 or 5 hereof.

     (b) Termination Without Just Cause.  The Corporation may terminate
         ------------------------------                                
Kemendo's employment without just cause, but in such event the Corporation shall
be obligated to pay to kemendo the compensation otherwise payable under Section
3(a) for the remainder of the 
<PAGE>
 
term of his employment as determined in Section 2, including any accrued
employee benefits and/or vacation pay. Any amount of such Section 3(a)
compensation in a gross amount before withholding taxes up to the greater of One
Hundred Thousand Dollars ($100,000) or the amount of Kemendo's combined federal
and state income taxes, if any, resulting from the Corporation's obligation to
pay such remaining Section 3 (a) compensation which are due in the year of
termination (or not later than the due date for the filing of Kemendo's
individual income tax returns for such year), shall be paid in cash thirty (30)
days following the date of Kemendo's termination. The amount, if any, of
Kemendo's Section 3(a) compensation exceeding such amount shall be paid in cash
in two equal annual installments, on the first and second anniversaries of
Kemendo's termination. No interest shall accrue on such payments, and the
Corporation shall deduct therefrom all normal employee withholding taxes. If the
Corporation terminates Kemendo's employment under this Section 6(b), the
incentive compensation otherwise due to Kemendo, if any, under Section 3(b)
shall be payable at the time(s) and in the form and manner set forth in Section
3(b). Termination of Kemendo's employment under this subsection 6(b) shall not
affect Kemendo's obligations under Sections 4 or 5 hereof. The foregoing
notwithstanding, Kemendo may, within ninety (90) days following the termination
of his employment under this Section 3 (b), notify the Corporation in accordance
with Section 8(b) that he has determined to take actions which would otherwise
violate Section 4 hereof. In such case, and subject to the following conditions,
Kemendo shall be relieved of his obligations under Section 4 hereof. In order to
be relieved of such Section 4 obligations, Kemendo agrees that his compensation
under Sections 3(a) and 3(b) shall terminate as of the date of his termination,
and Kemendo shall forfeit and return to the Corporation any Section 3(a)
compensation and evidences of indebtedness of the Corporation there for
applicable to periods after his termination; Kemendo's Section 3(b) compensation
shall accrue only to the date of his termination and it shall be paid as and
when it would otherwise be paid under Section 3 (b). Kemendo may be terminated
under this Section 6(b) only by a seventy five percent (75%) vote of the Board
of Directors of the Corporation, including Kemendo's if he is a director of the
Corporation at the time the vote is taken. The Corporation shall have the right
to prepay all or any part of any payments provided for in this Section 6(b) at
any time without penalty.

     (c) Termination by Kemendo. Kemendo may terminate his employment at any
         ----------------------                                             
time on thirty (30) days prior written notice to the Corporation, and in such
event, the Corporation shall be obligated to pay Kemendo his Section 3(a)
compensation only up to the date of termination, including any accrued employee
benefits and/or vacation pay. If Kemendo dies during the term of this Agreement,
his compensation shall continue only to the date of his death. If he becomes
disabled such that he cannot perform his principal duties hereunder for a period
of longer than three (3) months, the Corporation may terminate his employment
after the end of such three (3) month period and in such event Kemendo's
compensation shall terminate at such date. Termination under this subsection
6(c) shall 
<PAGE>
 
not affect Kemendo's obligations under Sections 4 or 5. If Kemendo's employment
terminates under this Section 6(c), the incentive compensation otherwise due to
Kemendo under Section 3(b) shall accrue to the date of termination of his
employment under this Section 6(c). The Corporation shall have the right to
prepay all or any part of any payments provided for in this Section 6(c) at any
time without penalty.

provision, covenant, duty or requirement made herein or required herein on its
part, then Kemendo, in his sole discretion, shall be entitled to (i) actual

Agreement by the Corporation and an injunction restraining the Corporation from
violating the terms of this Agreement, and (iii) to the fullest extent permitted
by applicable law, recovery of his attorneys fees, court costs, and all related

wellbore is used to drill three laterals, the number of "Curved Boreholes" is
three. Similarly, if a one vertical wellbore is used to drill two laterals and
if another vertical wellbore is used to drill only one lateral, the number of
"Curved Boreholes" is three.

For the purpose of this definition, a Curved Borehole is "Drilled" in performing
Licensed Service, if any part of a lateral is formed and drilling is not
                                                                     ---

feet and less than or equal to forty-five (45) feet; or

     at least ninety (90) feet for a curve whose radius is more than forty-five
(45) feet and less than or equal to sixty (60) feet.

For purposes of this definition, distance is measured from the kick-off point
(i.e., the location where an attempt is made to drill a curve borehole).

     1.13 "Anniversary Year" is the one year period beginning on the Effective
Date or the anniversary thereof.


                         ARTICLE II. GRANT TO LICENSEE
                         -----------------------------

Fifty Thousand Dollars ($50,000.00)         July 15, 2001 and every Anniversary
  multiplied by the Inflation Factor        Year thereafter.
- --------------------------------------------------------------------------------
</TABLE>

In the event that this Agreement expires or terminates before the end of an
Anniversary Year, LICENSEE agrees to pay to AMOCO the annual royalty set forth
above multiplied by the ratio (expressed as a decimal rounded to the nearest
one-tenth) of the number of calendar days that the Agreement was in effect to
the number three hundred and sixty-five (365). Such amount will be paid within
thirty (30) days of the effective date of termination or expiration date.

     FOR EXAMPLE, if during the eight Anniversary Year, the Agreement is
     terminated and the effective date of termination is on the 183rd day of
     that year, the annual royalty due to Amoco is $50,000.00 (multiplied by the
     Inflation Factor) multiplied by 0.5, where 0.5 = 183/365.

     3.03 Beginning on July 15, 2001 and during every Anniversary Year
thereafter, if the Curved Boreholes Drilled in any Anniversary Year (or pad
thereof, if this Agreement expires or is terminated before the end of that
Anniversary Year) are in excess of fifty (50), LICENSEE agrees to pay an
additional royalty of One Thousand Dollars ($1,000.00), multiplied by the
Inflation Factor, for each Curved Borehole Drilled after the first fifty Curved
Boreholes. Such amount will be paid within thirty (30) days of the end of that
Anniversary Year.

     FOR EXAMPLE, if during the eight Anniversary Year, LICENSEE drills 60
     curved boreholes, the annual royalty during the fifth Anniversary 

                                       5
<PAGE>
 
          Year is $50,000.00 (multiplied by the Inflation Factor) for the first
          fifty Curved Boreholes Drilled and $10,000.00 (multiplied by the
          Inflation Factor) for the remaining ten Curved Boreholes Drilled, for
          a total of annual royalty of $60,000.00 (multiplied by the Inflation
          Factor). And if LICENSEE drills only 40 curved boreholes during the
          ninth Anniversary Year, the annual royalty is $50,000.00 (multiplied
          by the Inflation Factor).



                        ARTICLE IV. GRANT-BACK TO AMOCO

members of the Board. The Committee shall be appointed by the Board, which may
at any time, and from time to time, remove any member of the Committee, with or
without cause, appoint additional members to the Committee and fill vacancies,
however caused, in the Committee. A majority of the members of the Committee
shall constitute a quorum and all determinations of the Committee shall be made
by a majority of such quorum. Any decision or determination of the Committee

<PAGE>
 
Committee shall be fully as effective as if it had been made at a meeting duly
called and held. A Participant may receive Options under this Directors' Plan
whether or not such Participant also serves as a member of the Committee.

     (b)  Options shall be automatically granted to Participants in accordance
with Section 6 hereof and shall be issued upon terms and conditions set forth in
section 7 hereof. Accordingly, the persons to whom Options shall be granted, the
number of shares subject thereto and the material terms and conditions governing
the Options, will not be subject to the discretion of the Committee. However, if
any questions of interpretation of the Directors' Plan or of any Options issued
hereunder shall arise, they shall be determined by the Committee and such
determination shall be final and binding upon all persons having an interest in
the Directors' Plan.

     SECTION 6.  Terms and Conditions of Options; Stock Option Agreements.  Each
                 --------------------------------------------------------       
Option granted pursuant to this Directors' Plan shall be evidenced by a written
agreement between the Participant and the Company which shall contain the
following terms and conditions:

          (a)  Option Price.  The exercise price of each Directors' Option shall
               ------------                                                     
     bc one hundred percent (100%) of the fair market value of the shares
     subject to such Option on the date of grant.  For purposes of this Section,
     the fair market value of a share of Common Stock shall mean (i) in the
     event the Common Stock is not publicly traded, the fair market value on
     such day as determined in good faith by the Committee or (ii) in the event
     the Common Stock is publicly traded, the average of the last sale price of
     a share of Common Stock as reported by the principal quotation service on
     which the Common Stock is listed, for the ten business days preceding the
     date of grant; (iii) if last sale prices are not reported with respect to
     the Common Stock, the average of the high bid and low asked prices of a
     share of Common Stock as reported by such quotation service for the ten
     business days preceding the date of grant; or (iv) if bid and asked
     quotations are not reported, the average between the closing bid and asked
     prices of a share of Common Stock for the ten business days preceding the
     date of grant as furnished by a broker-dealer which regularly furnishes
     price quotations for the Common Stock.

          (b)  Medium and Time of Payment.  The exercise price of the shares to
               --------------------------                                      
     be purchased pursuant to a Directors' Option shall be paid (i) in full in
     cash or by check, (ii) by delivery (i.e. surrender) of shares of Common
     Stock of the Company then owned by the Participant with a Fair Market Value
     at the time of exercise of the Option equal to the exercise price, or (iii)
     by a combination of (i) and (ii).  
<PAGE>
 
          (c)  Term and Exercise of Options.  The term of each Option shall
               ----------------------------      
     commence on the date it is granted and, unless sooner terminated as set
     forth herein, shall expire ten years and thirty days after its date of
     grant unless extended as set forth herein. If the Participant shall die or
     become disabled within the meaning of Section 22(3) (e) of the Internal
     Revenue Code of 1986, as amended, while still serving as a director or
     prior to the termination of the Option in accordance with the preceding
     sentence, the Option shall terminate on the anniversary of the
     Participant's death or disability, as the case may be. In the event of the
     Participants death, the Option may be exercised by the person or persons
     entitled to do so under the Participant's will or,if the Participant shall
     fail to make testamentary disposition of the Option, or shall die
     intestate, by the Participant's legal representative.

          (d)  Transferability.  Each Option shall be nontransferable by the
               ---------------                                              
     Participant except by will or by the laws of descent and distribution, and
     shall be exercisable during the Participant's lifetime only by him.

          (e)  Investment Purpose.  Each Participant shall represent and warrant
               ------------------                                               
     that he is acquiring the Option and in the event the Option is exercised,
     the shares of Common Stock issuable thereunder, for investment, for his own
     account and not with a view to the distribution thereof, and that he will
     not offer or sell the shares unless a registration statement under the
     Securities Act of 1933, as amended (the "Securities Act") and any
     applicable state securities law is in effect, or unless counsel
     satisfactory to the Company renders a reasoned opinion that the proposed
     sale is exempt from the registration requirements of the Securities Act and
     such state security act.

     SECTION 8.  Adjustment of Number of Shares.  In the event that a dividend
                 ------------------------------                               
shall be declared upon the shares of Common Stock payable in shares of Common
Stock, the number of shares of Common Stock then subject to any option granted
hereunder, and the number of shares reserved for issuance pursuant to this
Directors' Plan but not yet covered by an Option, shall be adjusted by adding to
each of such shares the number of shares which would be distributable thereon if
such share had been outstanding on the date fixed for determining the
stockholders entitled to receive such stock dividend. In the event that the
outstanding shares of Common Stock shall be changed into or exchanged for a
different number or kind of shares of stock or other securities of the Company
or of another corporation, whether through reorganization, recapitalization,
stock split-up, combination or shares, merger or consolidation, then there shall
be substituted for each share of Common Stock subject to any such Option and for
each share of Common Stock reserved for issuance pursuant to this Directors'
<PAGE>
 
Plan but not yet covered by an Option, the number and kind of shares of stock or
other securities into which each outstanding share of Common Stock shall be so
changed or for which each such share shall be exchanged. In the case of any such
substitution or adjustment as provided for in this Section, the option price in
each stock option agreement for each share covered thereby prior to such
substitution or adjustment will be the total option price for all shares of
stock or other securities which shall have been substituted for each such share
or to which such share shall have been adjusted pursuant to this Section 8. No
adjustment or substitution provided for in this Section shall require the
Company, in any stock option agreement, to sell a fractional share, and the
total substitution or adjustment with respect to each stock option agreement
shall be limited accordingly.

     SECTION 9.  Effective Date and Term of Plan.  Subject to approval by the
                 -------------------------------                             
stockholders of the Company, this Plan shall become effective as of the date of
its adoption by the Board of Directors of the Company.  Except to the extent
necessary to govern outstanding Options issued, this Plan shall terminate on,
and no additional Options shall be granted after, the third anniversary of its
effective date unless earlier terminated by the Board of Directors in accordance
with Section 10 Thereof.

     SECTION 10.  Amendment of the Plan.  This Plan may be terminated or
                  ---------------------                                 
amended from time to time by vote of the Board of Directors; provided, however,
that no such termination or amendment shall materially adversely affect or
impair any then outstanding Directors' Option without the consent of the
Participant and no amendment which shall (i) increase the maximum number of
shares subject to this Directors' Plan; (ii) increase the maximum number of
shares issuable to any Participant under this Directors' Plan; or (iii) change
the designation of Participants eligible to receive Options under this
Directors' Plan, shall be effective without the approval of the stockholders.

Options and Non-incentive Stock Options shall be collectively referred to herein
as "Options".

     SECTION 3.  Eligibility.  All employees of the Company or any of its
                 -----------

     SECTION 5.  Administration.
                 -------------- 

     (a) This Plan shall be administered by the committee (the "Committee")
referred to in paragraph (b) of this Section. Subject to the express provisions
of this plan, the Committee shall have regulations relating to it, to determine
the terms and provisions of the respective option agreements (which need not be
identical), to determine the Grantees to whom, and the times and the prices at
which, Options shall be granted, the option periods, the number of shares of the
Common Stock to be subject to each Option and whether each Option shall be an
Incentive Stock Option or a Non-incentive Stock Option, and to make all other
determinations necessary or advisable for the administration of the Plan.  Each
Option shall be clearly identified at the time of grant as to its status.  In
making such determinations, the Committee may take into account the nature of
the services rendered by the respective Grantees, their present and potential
contributions to the success of the Company and such other factors as the
Committee, in its discretion, shall deem relevant.  Nothing contained in this
Plan shall be deemed to give any Grantee any right to be granted an Opt ion to
purchase shares of Common Stock except to the extent and upon such terms and
conditions as may be determined by the Committee.  The Committee's determination
on all of the matters referred to in this Section 5 shall be conclusive.

     (b) The Committee shall consist of from three (3) to five (5) individuals
who may, but need not, be members of the Board. Each member of the Committee
shall be a person who, at the time of his appointment to, and at all times
during his service as a member of, the Committee is a "disinterested person" as
that term is then defined under Regulation 16b-3 promulgated under the
Securities Exchange Act of 1934, as amended, or any successor statute or
regulation regarding the same subject matter.  The Committee shall be appointed
by the Board, which may at any time, and from time to time, remove any member of
the Committee, with or without cause, appoint additional members to the
Committee and fill vacancies, however caused, in the Committee.  A majority of
the members of the Committee shall constitute a quorum and all determinations of
the Committee shall be made by a majority of such quorum.  Any decision or
determination of the Committee reduced to writing and signed by all of the
members of the Committee shall be fully as effective as if it had been made at a
meeting duly called and held.

     (c) The Committee may at its election provide in any option agreement
covering the grant of Options under this Plan that, upon the exercise of such
Options, the Company will loan to the holder thereof such amount as shall equal
the purchase price of the 
<PAGE>
 
shares of Common Stock issuable upon such exercise, such loan to be on terms and
conditions deemed appropriate by the Committee.

     (d) Notwithstanding any provision hereof to the contrary, the Committee
shall have sole and exclusive authority with respect to the grant of Options to
Directors.

     SECTION 6.  Terms of Incentive Stock Options.  Each Incentive Stock Option
                 --------------------------------                              
granted under this Plan shall be evidenced by an Incentive Stock Option
Agreement which shall be executed by the Company and by the person to whom such
Incentive Stock Option is granted, and shall be subject to the following terms
and conditions:

          (a) The price at which shares of Common Stock covered by each
     Incentive Stock Option may be purchased pursuant thereto shall be
     determined in each case on the date of grant by the Committee, but shall be
     an amount not less than the par value of such shares and not less than the
     fair market value of such shares on the date of grant.  For purposes of
     this Section, the fair market value of shares of Common Stock on any day
     shall be (i) in the event the Common Stock is not publicly traded, the fair
     market value on such day as determined in good faith by the Committee or
     (ii) in the event the Common Stock is publicly traded, the last sale price
     of a share of Common Stock as reported by the principal quotation service
     on which the Common Stock is listed, if available, or, if last sale prices
     are not reported with respect to the Common Stock, the mean of the high bid
     and low asked prices of a share of Common Stock as reported by such
     quotation service for such day, such fair market value shall be the average
     of (i) the last sale price (or, if last sale prices are not reported with
     respect to the Common Stock, the mean of the high bid and low asked prices)
     on the day next preceding such day for which there was a report and (ii)
     the last sale price (or, if last sale prices are not reported with respect
     to the Common Stock, the mean of the high bid and low asked prices) on the
     day next succeeding such day for which there was a report, or as otherwise
     determined by the Committee in its discretion pursuant to any reasonable
     method contemplated by Section 422A of the Code and any regulations issued
     pursuant to that Section.

          (b) The option price of the shares to be purchased pursuant to each
     Incentive Stock Option shall be paid in full in cash, or by delivery (i.e.
     surrender) of shares of Common Stock of the Company then owned by the
     Grantee, at the time of the exercise of the Incentive Stock Option.  Shares
     of Common Stock so delivered will be valued on the day of delivery for the
     purpose of determining the extent to which the option price has been paid
     thereby, in the same manner as provided for the purchase price of Incentive
     Stock Options as

     set forth in paragraph (a) of this Section, or as otherwise determined by
     the Committee, in its discretion, pursuant to any reasonable method
     contemplated by Section 422A of the Code and any regulations issued
     pursuant to that Section.

          (c) Each Incentive Stock Option Agreement shall provide that such
     Incentive Stock Option may be exercised by the Grantee, in such parts and
     at such times as nay be specified in such Agreement, within a period not
     exceeding ten years after the date on which the Incentive Stock Option is
     granted (hereinafter called the "Incentive Stock Option Period") and, in
     any event, only during the continuance of the employee's employment by the
     Company or any of its Subsidiaries or during the period of three months
     after the termination of such employment to the extent that the right to
     exercise such Incentive Stock Option had accrued at the date of such
     termination; provided, however, that if Incentive Stock Options as to 100
     or more shares are held by a Grantee, then such Incentive Stock Options may
     not be exercised for less than 100 shares at any one time, and if Incentive
     Stock Options for less than 100 shares are held by a Grantee, then
     Incentive Stock Options for all such shares must be exercised at one time;
     and provided, further, that if the Grantee, while still employed by the
     Company or any of its Subsidiaries, shall die within the Incentive Stock
     Option Period, the Incentive Stock Option may be exercised, to the extent
     specified in the Incentive Stock Option Agreement, and has herein provided,
     but only prior to the first to occur of:

               (i) the expiration of the period of one year after the date of
     the Grantee's death, or

               (ii) the expiration of the Incentive Stock Option Period, by the
          person or persons entitled to do so under the Grantee's will, or, if
          the Grantee shall fail to make testamentary disposition of said
          Incentive Stock Option, or shall die intestate, by the Grantee's legal
          representative or representatives.

          (d) Each Incentive Stock Option granted under this Plan shall by its
     terms be nontransferable by the Grantee except by will or by the laws of
     descent and distribution, and each Incentive stock Option shall by its
     terms be exercisable during the Grantee's lifetime only by him.

          (e) Notwithstanding the foregoing, if an Incentive Stock Option is
     granted to a person at any time when such person owns, within the meaning
     of Section 425(d) of the Code, more that 10% of the total combined voting
     power of all classes of stock of the employer corporation (or a parent or
     subsidiary of such corporation within the meaning of Section 425 of the
     Code) the price at which each share of Common Stock Covered 
<PAGE>
 
     by such Incentive Stock Option may be purchased pursuant to such Incentive
     stock Option shall not be less than 110% of the fair market value
     (determined as in paragraph (a) of this Section) of the shares of Common
     stock at the time the Incentive stock Option is granted, and such Incentive
     Stock Option must be exercised within a period specified in the Incentive
     Stock Option Agreement which does not exceed five years after the date on
     which such Incentive Stock Option is granted.

          (f) The Incentive Stock Option Agreement entered into pursuant hereto
     may contain such other terms, provisions and conditions not inconsistent
     herewith as shall be determined by the Committee including, without
     limitation, provisions (i) requiring the giving of satisfactory assurances
     by the Grantee that the shares are purchased for investment and not with a
     view to resale in connection with a distribution of such shares, and will
     not be transferred in violation of applicable securities laws, (ii)
     restricting the transferability of such shares during a specified period
     and (iii) requiring the resale of such shares to the Company at the option
     price if the employment of the employee terminates prior to a specified
     time.  In addition, the Committee, in its discretion, may afford to holders
     of Incentive Stock Options granted under this Plan the right to require the
     Company to cause to be registered under the Securities Act of 1933, as
     amended, for public sale by the holders thereof, shares of Common Stock
     subject to such Incentive Stock Options upon such terms and subject to such
     conditions as the Committee may determine to be appropriate.

          (g) In the discretion of the Committee, a single Stock Option
     Agreement may include both Incentive Stock Options and Non-incentive Stock
     Options, or those options may be included in separate stock option
     agreements.

     SECTION 7.  Terms of Non-incentive Stock Options.  Each Non-incentive Stock
                 ------------------------------------                           
Option granted under this Plan shall be evidenced by a Non-incentive Stock
Option Agreement which shall be executed by the Company and by the person to
whom such Non-incentive Stock Option is granted, and shall be subject to the
following terms and conditions.

          (a) The price at which shares of Common Stock covered by each Non-
     incentive Stock Option may be purchased pursuant thereto shall be an amount
     not less than the par value of such shares.

          (b) Each Non-incentive Stock Option Agreement shall provide that such
     Non-incentive Stock Option may be exercised by the Grantee, in such parts
     and at such times as may be specified in such Agreement, within a period up
     to and
<PAGE>
 
     including ten years and thirty days after the date on which the Non-
     incentive Stock Option is granted.

     (c)  Each Non-incentive Stock Option granted under this Plan shall by its
     terms be non-transferable by the optionee except by will or by the laws of
     descent and distribution, and each Non-incentive Stock Option shall by its
     terms be exercisable during the Grantee's lifetime only by him.

     (d)  The Non-incentive Stock Option Agreement entered into pursuant hereto
     may contain such other terms, provisions and conditions not inconsistent
     herewith as shall be determined by the Committee, in its sole discretion,
     including without limitation the terms, provisions and conditions set forth
     in Section 6(f) with respect to Incentive Stock Option Agreements.

     SECTION 8.  Limit on Option Amount.  Notwithstanding any provision
                 ----------------------                                
contained herein, the aggregate fair market value (determined under Section 6(a)
as of the time such Incentive Stock Options are granted) of the shares of Common
Stock with respect to which Incentive Stock Options are first exercisable by any
employee during any calendar-year (under all stock option plans of the
employee's employer corporation and its parent and subsidiary corporation within
the meaning of Section 425 of the Code) shall not exceed $100,000. An option may
be granted which exceeds this $100,000 limitation, as long as under then
applicable law only the portion of such an option which is exercisable for
shares of Common Stock in excess of the $100,000 limitation shall be treated as
a Non-incentive Stock Option.  The limit in this paragraph shall not apply to
options which are designated as Non-incentive Stock Options, and, except as
otherwise provided herein, there shall be no limit on the amount of such options
which may be first exercisable in any year.

     SECTION 9.  Adjustment of Number of Shares.  ln the event that a dividend
                 ------------------------------                               
shall be declared upon the shares of Common stock payable in shares of Common
Stock, the number of shares of Common Stock then subject to any option granted
hereunder, and the number of shares reserved for issuance pursuant to this Plan
but not yet covered by an option, shall be adjusted by adding to each of such
shares the number of shares which would be distributable thereon if such share
had been outstanding on the date fixed for determining the stockholders entitled
to receive such stock dividend. In the event that the outstanding shares of
Common Stock shall be changed into or exchanged for a different number or kind
of shares of stock or other securities of the Company or of another corporation,
whether through reorganization, recapitalization, stock split-up, combination or
shares, merger or consolidation, then there shall be substituted for each share
of Common Stock subject to any such Option and for each share of Common Stock
reserved for issuance pursuant to the Plan but not 
<PAGE>
 
yet covered by an Option, the number and kind of shares of stock or other
securities into which each outstanding share of Common Stock shall be so changed
or for which each such share shall be exchanged; provided, however, that in the
event that such change or exchange results from a merger or consolidation, and
in the judgment of the Board of Directors such substitution cannot be effected
or would be inappropriate, or if the Company shall sell all or substantially all
of its assets, the Company shall use reasonable efforts to effect some other
adjustment of each then outstanding Option which the Board of Directors, in its
sole discretion, shall deem equitable. In the event that there shall be any
change, other than as specified above in this Section 9, in the number or kind
of outstanding shares of Common Stock or of any stock or other securities into
which such shares of Common Stock shall have been changed or for which they
shall have been exchanged, then, if the Board of Directors shall determine that
such change equitable requires an adjustment in the number or kind of shares
theretofore reserved for issuance pursuant to the Plan but not yet covered by an
Option and of the shares then subject to an Option or Options, such adjustment
shall be made by the Board of Directors and shall be effective and binding for
all purposes of this Plan and of each stock option agreement. Notwithstanding
the foregoing, if any adjustment in the number of shares which may be issued and
sold pursuant to Options is required by the Code or regulations issued pursuant
thereto to be approved by the stockholders in order to enable the Company to
issue Incentive Stock Options pursuant to this Plan, then no such adjustment
shall be made without the approval of the stockholders. In the case of any such
substitution or adjustment as provided for in this Section, the option price in
each stock option agreement for each share covered thereby prior to such
substitution or adjustment will be the total option price for all shares of
stock or other securities which shall have been substituted for each such share
or to which such share shall have been adjusted pursuant to this Section 9. No
adjustment or substitution provided for in this Section 9 shall require the
Company, in any stock option agreement, to sell a fractional share, and the
total substitution or adjustment with respect to each stock option agreement
shall be limited accordingly. Notwithstanding the foregoing, in the case of
Incentive Stock Options, if the effect of the adjustments or substitution is to
cause the Incentive Stock Option to fail to continue to qualify as an Incentive
Stock Option or to cause a modification, extension or renewal of such Incentive
Stock Option within the meaning of Section 425 of the Code, the Board of
Directors shall use reasonable efforts to effect such other adjustment of each
then outstanding option as the Board of Directors, in its sole discretion, shall
deem equitable.

     SECTION 10.  Amendments.  This Plan may be terminated or amended from time
                  ----------                                                   
to time by vote of the Board of Directors; provided, however, that no such
termination or amendment shall materially adversely affect or impair any then
outstanding Option 
<PAGE>
 
without he consent of the Grantee thereof and no amendment which shall (i)
change the total number of shares which may be issued and sold pursuant to
Options granted under this Plan, or (ii) change the designation of employees
eligible to receive Incentive Stock Options or the class of employees or other
persons eligible to receive Options, shall be effective without the approval of
the stockholders. Notwithstanding the foregoing, the Plan may be amended by the
Committee to incorporate any amendments made to the Code which the Committee
deems to be necessary or desirable to preserve incentive stock option status for
outstanding Incentive Stock Options and to preserve the ability to issue
Incentive Stock Options pursuant to this Plan.

     SECTION 11.  Termination.  Except to the extent necessary to govern
                  -----------                                           
outstanding Options, this Plan shall terminate on, and no additional Options
shall be granted after, ten years from the date the Plan is adopted, or ten
years from the date the Plan is approved by the stockholders, whichever is
earlier.

Mr. Bud E. Livingston
Kato Operating Company
P.O. Box 960
Bristow, OK 74010

RE:  Northwest Antelope Mississippi Chat Unit
     Garfield County, and Noble County, Oklahoma

Dear Bud:

     Pursuant to our conversation yesterday, the following represents my
understanding of the agreement reached between Pan Western Energy Corporation
("PWEC") and Bud E. Livingston ("BEL"):

1.   Pan Western will pay to BEL monthly, commencing with February 1, 1996
production revenues, an amount equal to 3.93694% of net revenues less 4.77328%
of the lease operating expenses attributable to the above referenced unit.

2.   Notwithstanding Paragraph 1. above, PWEC will receive the first Six
Thousand Dollars ($6,000.00) of net revenues less lease operating expenses
attributable to the BEL interest prior to BEL receiving any distributions
attributable to said interest.

3.   PWEC will pay all workover costs associated with the implementation of the
water flood unit hereinabove described and no such costs will be attributed to
the BEL interest.

4.   In consideration of the remuneration described in Paragraphs 1., 2., and
3., above, BEL will provide to PWEC evaluation and reservoir engineering
services relating to the following fields and wells:

     A.   Centrahoma Field, Coal County, Oklahoma
     B.   Borden County, Texas Wells
     C.   West Flowers Unit, Stonewall County, Texas

5.   The evaluation and reservoir engineering services to be provided by BEL to
PWEC shall be designed to result in recommendations by BEL to PWEC as to how
PWEC can maximize the recovery of all its oil 
<PAGE>
 
and gas reserves located in and under the hereinabove described fields and/or
wells set forth in Paragraph 4. BEL's recommendations will be accompanied by
supporting data as deemed necessary and appropriate to assist PWEC with its
annual independent reserve report and sale of any prospect(s), re-works or
developmental opportunities identified by BEL in the areas hereinabove set forth
in Paragraph 4.

6.   For purposes of this agreement, the order of priority of the projects to be
undertaken by BEL will be as set forth in Paragraph 4. above.  Since it is
understood by both parties that time is of the essence, the overall services to
be performed by BEL will be completed by June 30, 1996.  BEL's services relating
to the Centrahoma Field, Coal County, Oklahoma will be completed by February 21,
1996.

7.   The effective date of this agreement is February 1, 1996.

     If the above summation clearly reflects your understanding of the agreement
reached between Pan Western Energy Corporation and yourself, please execute the
enclosed copy of this letter where indicated and return same to the undersigned
as soon as possible.

          My best regards,

Gentlemen:

Pan Western has requested that a review of audited reserves be performed on the
attached properties. We reviewed company records and verified these against
public production records. Based on our observations, the following value is
presented:

</TABLE> 
              

METHOD OF APPRAISAL

The properties were evaluated on the basis of future net cash flow, which is
defined as the amount of income estimated to accrue to the appraised interest by
operation of the property to its economic limit. Future net cash flow values
were determined for various discount rates. Discounting was performed by
compounding continuously.
<PAGE>
 
GENERAL ASSUMPTIONS

PRICES -  The oil and gas price was initiated at the December 1996 price for
each property. No escalation was applied.

OPERATING EXPENSES - The operating expenses were supplied by Pan Western based
on the past twelve months and recent changes to gathering systems. These have
been reviewed and appear to be reasonable. No overhead charges were applied.

SALVAGE VALUE -  Salvage value or plug and abandonment expenses were not
included in the cashflow models. Normally the two will equalize, and any surplus
or expense is insignificant due to time delay.

SEVERANCE TAX -  A severance tax of 7.095% on all products was applied to
Oklahoma wells. Texas severance tax was applied at 4.6% for oil, and 7.5% for
gas. Kansas severance tax was applied at 8%. No ad valorem tax has been applied.


                              RESERVE CATEGORIES

PROVED PRODUCING -  Proved producing as defined by the Society of Petroleum
Engineers, February 27, 1989 are "Estimates of volumes of crude oil, condensate,
natural gas, natural gas liquids, and associated substances anticipated to be
commercially recoverable from a known accumulation from a given date forward,
under existing conditions, by established operating practices and current
government regulations. Proved reserves must have facilities to process and
transport to market that are operational at the time of the estimate, or
reasonable expectation to install such facilities in the future."

PROVED NONPRODUCING - Proved producing reserves are defined as reserves from
zones in existing wells that have not been previously perforated or stimulated.
The reserves have been weighted to account for factors such as production type,
subnormal pressure, log abnormalities, and partial recovery of oil and gas in
place by offset production. Because expenditures occur during recompletion, each
well is assigned adequate investment funds. These reserves have a higher risk
associated with them as compared to PROVED PRODUCING.

PROVED UNDEVELOPED - Proved undeveloped reserves are defined as reserves from
established produced zones that will require expenses in excess of a simple
recompletion attempt. This can include offset drilling and side track drilling
of existing wells. These reserves have a higher risk associated with them as
compared to PROVED NONPRODUCING.
<PAGE>
 
                             RESERVE DETERMINATION


PROVED PRODUCING - These reserves were determined by production decline curve
analysis, supported when available by P/Z plots. No volumetric analysis was
applied.

PROVED NONPRODUCING AND UNDEVELOPED - These reserves were prepared based on
previous work and reservoir studies by Conoco, Sun Oil, and KATO Operating
Company. More recent work on horizontal sidetracking from existing wellbores was
prepared as a joint effort of KATO and SYCAMORE. We find that the reserves
portrayed are reasonable, and that the assumptions used are conservative in
nature.

COALGATE FIELD - PDP
An increase in production is noted in this field due to the drop in gathering
line pressure. This increases the net worth of the properties by lowering cost
and increasing rates.

NORTHWEST ANTELOPE - PDP
Production for 1996 indicates that an increase in production rate from remedial
work has been accomplished. In addition, the beginning of stimulation is
evidenced in some areas. Consequently, reserves equivalent to 100 MBBLS have
been moved from the Proved Nonproducing to the Proved Producing category. Pan
Western plans to continue remedial workovers and increase injection capacity.

WEST FLOWERS UNIT - PNP
This field is presently on a 4% decline. A reservoir study should be performed
in order to recover the full potential of the field. Expenditures and reserves
presented involve mostly recompletion and enhancement of existing wellbores.

HORIZONTAL DRILLING - PUD
The horizontal work presented in the PROVED UNDEVELOPED category require the use
of a relatively new but highly successful tool. The technique is short radius
sidetracking. A window is cut in the existing casing over the perforations. A
new hole is bored at a 900 angle into the existing zone for a distance of 400'
to 700'. The results to date in the industry have been good. We have tempered
the reserves not to exceed the ultimate recovery of the well being sidetracked.
This should be considered low on the risk scale of PUD.

                       REPRESENTATION AND QUALIFICATIONS

The gas balancing situation (if any) has not been addressed in this report. No
on site inspection was made of any of the properties by the evaluator. No effort
was made to check for equipment liens on the above properties.

No environmental audit was made of the properties, to ascertain what
requirements will be needed to bring the wells into
<PAGE>
 
compliance with state and federal regulations.  

The reserve estimates were determined in a manner consistent with accepted
engineering practice. However, because of the nature of oil and gas production,
the data quality, and the many variables involved, it should in no way be
construed that the properties are warranted to behave in the forecasted manner.
Additional activities on the leases, or information obtained subsequent to this
report will require revision of the stated value.

The use or release of this report constitutes an agreement of license with the
author, and releases the author from any liability thereof. Sycamore Resources
LLC, its employees and associates neither own nor expect to own any interest in
the wells, properties, or portions of companies which are partners of Pan
Western Energy, it's employees or associates.

We would be pleased to discuss the report in detail at your convenience.


                                        Respectfully submitted,
