Shares include 5,142,875 shares of Common Stock currently outstanding, 2,548,309
shares to be issued to various Selling Stockholders upon exercise of outstanding
warrants, up to 2,560,000 shares to be issued to certain Selling Stockholders
upon conversion of the outstanding 7% Secured Convertible Debentures due

      The Shares may be offered by the Selling Stockholders from time to time
in open market transactions (which may include block transactions) or otherwise
through the American Stock Exchange ("AMEX"), Canadian Dealing Network ("CDN"),
or in private transactions at prices relating to prevailing market prices or at
negotiated prices.  The Selling Stockholders may effect such transactions at
prices relating to prevailing market prices or at negotiated prices.  The
Selling Stockholders may effect such transactions by selling Shares to or
through broker-dealers, and such broker- dealers may receive compensation in
the form of discounts, concessions or commissions from the Selling Stockholders
and/or purchasers of the Shares, as the case may be, from whom such
broker-dealers may act as agent or to whom they sell as principal or both.  The
Selling Stockholders and any broker-dealer acting in connection with the sale
of the Shares offered hereby may be deemed to be "underwriters" within the
meaning of the Securities Act of 1933, as amended (the "Securities Act"), in
which event any discounts, concessions or commissions received by them, which
are not expected to exceed those customary in the types of transactions
involved, or any profit on resales of the Shares by them, may be deemed to be
underwriting commissions or discounts under the Securities Act.  See "Selling
Stockholders" and "Plan of Distribution."

      The costs, expenses and fees incurred in connection with the registration
of the Shares, which are estimated to be $115,000 (excluding selling
commissions and brokerage fees incurred by the Selling Stockholders), will be
paid by the Company.

      The Company's common stock, no par value (the "Common Stock"), is traded
on the AMEX under the symbol "KTN" and on the CDN under the symbol "CVZC."  On
March 10, 1998, the closing sales price of the Common Stock was US$1.63 per
share on the AMEX.  On January 30, 1998, the closing bid price was C$3.00 per
share on the CDN.  There have been no trades in the Company's Common Stock on

                                  THE COMPANY

GENERAL

         Cotton Valley Resources Corporation (referred to herein as either
"Cotton Valley" or the "Company") is an independent energy company engaged in
the exploration and development, acquisition and operation of oil and gas
properties with a geographic focus in major oil and gas producing regions in
the United States.  The Company was incorporated in the Province of Ontario,
Canada, originally as Cotton Valley Energy Limited, on February 15, 1995.  From
its inception through June 30, 1997, the Company was engaged principally in
organization and capitalization activities and did not generate material
revenues from operations.

         On June 30, 1995 in a one-for-one share and warrant exchange, the
Company acquired all the issued and outstanding shares of Cotton Valley Energy
Corporation ("CV Energy"), a Nevada corporation.  The Company intends to
conduct most of its acquisition, exploration and development of oil and gas
properties through CV Energy, which currently owns properties in Texas and an
option to participate in an offshore California exploration project.

         On June 14, 1996, the Company completed an amalgamation with Arjon
Enterprises, Inc. ("Arjon"), a Province of Ontario, Canada corporation.  As a
result of the Arjon amalgamation, the Company's name was changed to Cotton
Valley Resources Corporation and its shares of Common Stock began trading
through the Canadian Dealing Network.  Arjon was a public Canadian company
formed more than 50 years ago to operate a gold mine.  At the time of the
amalgamation, Arjon had not engaged in business for more than 25 years, it had
no material liabilities, and its only asset was a Cotton Valley Energy Limited
debenture in the amount of $146,300.  The stockholders of Arjon received
686,551 shares of Common Stock in the amalgamation.

         On April 30, 1996, the Company organized Cotton Valley Operating
Company, a Texas corporation ("CV Operating") to operate the Company's oil and
gas properties.  The Company on February 25, 1997, organized Cotton Valley
Energy, Inc., an Oklahoma corporation ("CVEI") to acquire and operate the N.E.
Alden Field properties in Caddo County, Oklahoma.  CVEI commenced operations on
March 3, 1997.  Aspen Energy Corporation, a Nevada corporation ("Aspen"), was
an inactive subsidiary of the Company formed on May 1, 1996, which was used to
accommodate the merger of Aspen Energy Corporation, a New Mexico corporation
("Old Aspen") into Aspen which was completed on July 31, 1997.  The principal
asset of Old Aspen was its interest in the Means Unit in Andrews County, Texas.

         On February 9, 1998, the Company continued into Canada's Yukon
Territory.  Under the law of the Yukon Territory, the Company's board of
directors need not be comprised of a majority of Canadian residents as
previously required under Ontario law.  Since the Company's principal offices,
management and properties are located in the United States, management believes
it is advantageous to have a majority of the Company's directors be residents
of the United States.  The Company may in the future continue from the Yukon
Territory to the State of Wyoming.





                                      -2-
<PAGE>   4

Management believes there are no significant differences in corporate law
concerning material stockholder rights between the Province of Ontario, the
Yukon Territory and the State of Wyoming.  The Company, at its annual meeting
held December 10, 1996, obtained stockholder approval for the continuance into
the Yukon Territory.

MUSTANG SERVICE COMPANIES

         In addition to CV Energy, CV Operating, CVEI and Aspen, the Company
recently organized Mustang Well Servicing Company, a Nevada corporation
("Mustang Well Servicing"), Mustang Oilfield Equipment Company, a Nevada
corporation ("Mustang Equipment"), and Mustang Horizontal Services, Inc., a
Nevada corporation ("Mustang Horizontal") (collectively, the "Mustang Service
Companies").  Mustang Equipment, Mustang Horizontal, Mustang Well Servicing, CV
Operating, CV Energy, CVEI and Aspen are currently wholly-owned Company
subsidiaries.  However, the Company has agreed to sell for nominal cost up to
15% of the common stock of Mustang Equipment, Mustang Horizontal and Mustang
Well Servicing to certain employees and officers of the Company, including
Eugene A. Soltero, Chairman of the Board, Chief Executive Officer, and James E.
Hogue, President and Chief Operating Officer. The total value of the 15%
interest to be received by these individuals is not expected to be significant
at the time of receipt based on the net book value of the companies.

         The Company believes that the current demand in the petroleum industry
for drilling and production equipment and services in general, and particularly
horizontal drilling equipment, provides the Company with an opportunity to
increase revenues and cash flow through the acquisition and refurbishment of
used oil field equipment and the use of well servicing rigs and related
equipment.  The Company has augmented its property acquisition and development
strategy with the addition of the Mustang Service Companies which the Company
believes can provide timely, quality services at competitive costs as well as
providing the Company with the capabilities to perform workovers, horizontal
drilling, and most significantly, the equipment and personnel necessary for the
Company to conduct its exploration and development activities.

CURRENT OPERATIONS

         Since January 1997, the Company has acquired oil and gas properties in
Oklahoma and Texas, certain horizontal drilling technology and equipment, and
two workover rigs and related equipment.  The Company also purchased and sold a
Canadian property.  To finance the acquisitions, the Company has raised capital
through the private sale of shares of Common Stock and warrants, the issuance
of debt instruments, including $4,320,000 of Convertible Debentures and from
July 1, 1997 through February 28, 1998, the exercise of options and warrants to
purchase approximately 1,677,609 shares of Common Stock for proceeds of
$2,920,122.  See "Business and Properties  -- Recent Developments."

         For the fiscal year ended June 30, 1997 and the six-month period ended
December 31, 1997, the Company recorded revenues of $276,230 and $1,157,985,
respectively, and had a net loss of $2,006,878 and a net profit of $54,403,
respectively.  As of December 31, 1997, the Company had an accumulated deficit
of $2,714,752 and working capital of $2,619,225.  The Company does not have a
bank line of credit.  The Company has funded its operating losses, acquisitions
and expansion costs primarily through a combination of private offerings of
debt and equity securities, including the issuance of the Convertible
Debentures.  See "Selected Historical Consolidated and Combined Financial
Information" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

BUSINESS STRATEGY

         The Company's current business strategy is to (i) continue to increase
reserves, production and cash flows by acquiring properties, or companies with
properties, with development opportunities, (ii) develop existing reserves
through low risk developmental drilling or recompletion programs, (iii)
concentrate on development activities within a limited number of core areas;
(iv) acquire and refurbish used oil field equipment for use in development
activities and for resale; and (v) provide well servicing for the Company's and
other wells.  Although the Company continuously is seeking acquisitions of
reserves and oil field equipment, there can be no assurance that the Company
will be able to identify and acquire reserves or oil field equipment upon terms
favorable to the Company or obtain the necessary financing on favorable terms.
See "Business and Properties."

<PAGE>   5


         The following are key elements of the Company's strategy:

         o       EXPLOITATION AND DEVELOPMENT OF EXISTING PROPERTIES.  The
                 Company has a significant inventory of exploitation projects,
                 including development drilling, workovers and recompletions.
                 The Company intends to maximize the value of its properties
                 through development activities including in-fill drilling,
                 waterflooding and other enhanced recovery techniques.

         o       MANAGEMENT OF OPERATING COSTS.  The Company emphasizes strict
                 cost controls in all aspects of its business and intends to
                 operate its properties wherever possible.  By operating its
                 properties, the Company believes it will be able to control
                 direct operating and drilling costs as well as to manage the
                 timing of development and exploration activities.

         o       PROPERTY ACQUISITIONS.  Although the Company has a significant
                 inventory of exploitation and development opportunities, it
                 continues to pursue strategic acquisitions which fit its
                 objectives of having Proved Reserves with development
                 potential and operating control.

         The success of the Company in maintaining positive working capital and
obtaining the necessary capital resources to fund future costs associated with
its operations and expansion plans is dependent upon the Company's ability to
(i) increase revenues through acquisitions and recovery of proved producing and
proved developed non- producing reserves; (ii) implement stringent costs
controls at the corporate administrative office and in field operations; (iii)
convert Convertible Debentures to equity; (iv) obtain the exercise of
outstanding warrants; and (v) obtain asset based commercial financing.
However, even if the Company achieves some success with its plans to maintain
or increase its working capital, there can be no assurance that it will be able
to generate sufficient revenues to achieve significant profitable operations or
fund its expansion and acquisition plans.

                              CURRENCY TRANSLATION

         The Company publishes annual financial statements in United States and

section of the Prospectus identify factors with respect to certain
forward-looking statements that could cause actual results to vary materially
from future results to which such forward-looking statements refer.  Other
factors which are not discussed in this section also could cause actual results
to vary materially from future results referred to in forward-looking
statements.  An investment in the securities offered hereby involves a high
degree of risk.  Prospective investors should consider carefully the following
risk factors in addition to the other information set forth in this Prospectus.

         LIMITED OPERATING HISTORY; CAPITAL INTENSIVE BUSINESS; NEED FOR
ADDITIONAL FUNDS.  From its inception in February 1995 through June 30, 1997,
the Company was engaged principally in organization and capitalization
activities and did not generate material revenues from operations.  The
Company's business is highly capital intensive requiring continuous development
and acquisition of oil and gas reserves.  In addition, capital is required to
operate and expand the Company's oil field operations and purchase equipment.
At December 31, 1997, the Company had a working capital of approximately
$2,600,000.  Because of the limited operating history of the Company and the
recent acquisitions of reserves and oil field equipment, the Company's working
capital requirements increased significantly over the last 12 months and are
expected to continue to do so.  The Company anticipates, based on its currently
proposed plans and assumptions relating to its operations, including proceeds
from the exercise of outstanding warrants, and proceeds from the private
offerings of debt and equity securities, together with cash expected to be
generated from operations, that it will be able to meet its cash requirements
for at least the next 12 months.  However, if such plans or assumptions change
or prove to be inaccurate, the Company could be required to seek additional
financing sooner than currently anticipated.  Although the Company is currently
negotiating with private investors and lenders with respect to additional
financing, the Company has no commitments to obtain any additional debt or
equity financing and there can be no assurance that additional funds will be
available, when required, on terms favorable to the Company.  Any future
issuances of equity securities would likely result in dilution to the Company's
then existing stockholders while the incurring of additional indebtedness would
result in increased interest expense and debt service changes.  See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business and Properties -- Business Strategy" and "-- Recent
Developments."

         CONSEQUENCES OF DEFAULT UNDER CONVERTIBLE DEBENTURES.  The Company has
$4,320,000 of outstanding 7% Secured Convertible Debentures due December 31,
2001 (the "Convertible Debentures"), representing approximately 16.1% of the
Company's capitalization at December 31, 1997.  The Convertible Debentures are
secured with approximately 25% of the Company's assets and are subject to
various operating and financial covenants.  The Company's ability to meet its
debt service obligations will depend on the Company's future operations, which
are subject to prevailing industry conditions and other factors, many of which
are beyond the Company's control.  In the event of a violation by the Company
of any of its loan covenants or any other default by the Company on its
obligations relating to its indebtedness, the lenders could declare such
indebtedness to be immediately due and payable and, in certain cases, foreclose
on some of the Company's assets.  Moreover, to the extent that 25% of the
Company's assets continue to be pledged to secure outstanding indebtedness
under the Convertible Debentures, such assets will not be available to secure
additional indebtedness, which may adversely affect the Company's ability to
borrow in the future.  See "Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Business and Properties -- Recent
Developments; Sale of Convertible Debentures" and "Description of Securities --
Convertible Debentures."

         HISTORY OF LOSSES.  The Company incurred operating losses of $712,360
and $2,006,878 for the fiscal years ended June 30, 1996, and 1997,
respectively, and had a net profit of $54,403 for the six-month period ended
December 31, 1997.  The Company's accumulated deficit as of December 31, 1997
was $2,714,752.  The





                                       -8-
<PAGE>   10
Company does not have a bank line of credit.  The Company has funded its
operating losses, acquisitions and expansion costs primarily through a
combination of the private offerings of debt and equity securities, including
the issuance of the Convertible Debentures.  The success of the Company in
obtaining the necessary capital resources to fund future costs associated with
its operations and expansion plans is dependent upon the Company's ability to
(i) increase revenues through acquisitions and recovery of the Company's proved
producing and proved developed non-producing revenues; (ii) implement stringent
costs controls at the corporate administrative office and in field operations;
(iii) convert the Convertible Debentures to equity; (iv) obtain the exercise of
outstanding warrants; and (v) obtain asset based commercial financing. However,
even if the Company achieves some success with its plans, there can be no
assurance that it will be able to generate sufficient revenues to achieve
significant profitable operations or fund its expansion and acquisition plans.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations."

         SIGNIFICANT CAPITAL EXPENDITURES NECESSARY FOR UNDEVELOPED PROPERTIES.
Except for its recent acquisition of properties in Oklahoma and Texas, almost
all of the Company's Proved Reserves are classified as proved undeveloped,
meaning very little production currently exists.  Recovery of the Company's
proved undeveloped reserves will require significant capital expenditures.
Management estimates that aggregate capital expenditures of approximately $20
million will be required to fully develop these reserves, of which $6 million
is expected to be incurred during calendar 1998.  No assurance can be given
that the Company's estimates of capital expenditures will prove accurate, that
its financing sources will be sufficient to fully fund its planned development
activities or that development activities will be either successful or in
accordance with the Company's schedule.  Additionally, any significant decrease
in oil and gas prices or any significant increase in the cost of development
could result in a significant reduction in the number of wells drilled and/or
reworked.  No assurance can be given that any wells will produce oil or gas in
commercially profitable quantities.  See "Management's Discussion and Analysis 
of Financial Condition and Results of Operations" and "Business and Properties
- -- Description of Properties" and "-- Oil and Gas Reserves."

         NO ASSURANCE OF ADDITIONAL FINANCING.  Development of the Company's
properties will require additional capital resources.  Although the Company is
presently negotiating with private lenders and investors with respect to
sources of additional financing, the Company has no commitments to obtain any
additional debt or equity financing and there can be no assurance that
additional financing will be available, when required, on favorable terms to
the Company.  The inability to obtain additional financing would have a
material adverse effect on the Company, including requiring the Company to
curtail significantly its oil and gas acquisition and development plans or
farm-out development of its properties.  Any additional financing may involve
substantial dilution to the interests of the Company's stockholders at that
time.  See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business and Properties."

         INCREASED CASH FLOW DEPENDENT UPON ABILITY TO DEVELOP CURRENT
PROPERTIES AND ACQUIRE ADDITIONAL RESERVES.  The Company's future oil and gas
reserves and production, and therefore its cash flows, are highly dependent
upon its success in exploiting its current reserve base and acquiring or
discovering additional reserves.  Without the addition of reserves through
acquisition, exploration or development activities, the Company's reserves and
production will decline over time as reserves are exploited.  The business of
exploring for, developing or acquiring reserves is capital intensive.  To the
extent cash flows from operations are insufficient and external sources of
capital become limited or unavailable, the Company's ability to make the
necessary capital investments to maintain and expand its oil and gas reserves
will be impaired.  In addition, no assurance can be given that the Company will
be able to find and develop or acquire additional reserves to replace
production at acceptable costs.

         DEPENDENCE UPON COMPANY'S ABILITY TO MANAGE GROWTH AND EXPANSION.  The
Company's ability to manage its growth, if any, will require it to continue to
improve and expand its management, operational and financial systems and
controls.  Any measurable growth in the Company's business will result in
additional demands on its management, administrative, operation, financial and
technical resources.  There can be no assurance that the Company will be able
to successfully address these additional demands.  There also can be no
assurance that the Company's operating and financial control systems will be
adequate to support its future operations and anticipated growth.  Failure to
manage the Company's growth properly could have a material adverse effect upon
the Company's business, financial condition and results of operations.  The
Company may also seek potential acquisitions of oil and gas properties and
related service businesses that could complement or





                                       -9-
<PAGE>   11
expand the Company's business.  In the event the Company were to identify an
appropriate acquisition candidate, there is no assurance that the Company would
be able to successfully negotiate, finance or integrate such acquired
properties or businesses into current operations.  Furthermore, such an
acquisition could cause a diversion of management's time and resources.  There
can be no assurance that a given acquisition, when consummated, would not
materially adversely effect the Company's business and results of operations.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business and Properties" and "Management."

         ACQUISITION RISKS.  The Company has grown primarily through
acquisitions and intends to continue acquiring oil and gas properties.
Although the Company performs a review of the properties proposed to be
acquired, such reviews are subject to uncertainties.  It generally is not
feasible to review in detail every individual property involved in an
acquisition.  Ordinarily, management review efforts are focused on the
higher-valued properties.  However, even a detailed review of all properties
and records may not reveal existing or potential problems; nor will it permit
the Company to become sufficiently familiar with the properties to assess fully
their deficiencies and capabilities.  Inspections are not always performed on
every well, and potential problems, such as mechanical integrity of equipment
and environmental conditions that may require significant remedial
expenditures, are not necessarily observable even when an inspection is
undertaken.  See "Business and Properties -- Business Strategy."

         The Company has recently begun to focus its acquisition efforts on
larger packages of oil and gas properties, such as the properties included in
the East Binger Unit and Zama Lake Property.  The acquisition of larger oil and
gas properties may involve substantially higher costs and may pose additional
issues regarding operations and management.  There can be no assurance that oil
and gas properties acquired by the Company will be successfully integrated into
the Company's operations or will achieve desired profitability objectives.  See
"Business and Properties -- Recent Developments."

         EXPLORATION AND DEVELOPMENT RISKS; WATERFLOOD PROJECTS.  The Company
intends to increase its development and, to a lesser extent, exploration
activities.  The Company does not intend to engage in any significant
exploration drilling activities in 1998.  Exploration drilling and, to a lesser
extent, development drilling of oil and gas reserves involve a high degree of
risk that no commercial production will be obtained and/or that production will
be insufficient to recover drilling and completion costs.  The cost of
drilling, completing and operating wells is often uncertain.  The Company's
drilling operations may be curtailed, delayed or canceled as a result of
numerous factors, including title problems, weather conditions, compliance with
governmental requirements and shortages or delays in the delivery of equipment.
Furthermore, completion of a well does not assure a profit on the investment or
a recovery of drilling, completion and operating costs.  See "Business and
Properties -- Development and Exploration Activities."

         There are certain risks associated with secondary recovery operations,
especially the use of waterflooding techniques, and drilling activities in
general.  Part of the Company's inventory of development prospects consists of
waterflood projects.  Waterflooding involves significant capital expenditures
and uncertainty as to the total amount of secondary reserves that can be
recovered.  In waterflood operations, there is generally a delay between the
initiation of water injection into a formation containing hydrocarbons and any
increase in production that may result.  The operating cost per unit of
production of waterflood projects is generally higher during the initial phases
of such projects due to the purchase of injection water and related costs, as
well as during the later stages of the life of the project as production
declines.  The degree of success, if any, of any secondary recovery program
depends on a large number of factors, including the porosity of the formation,
the technique used and the location of injector wells.  See "Business and
Properties --  Development and Exploration Activities."

         VOLATILITY OF OIL AND GAS PRICES.  The Company's revenues,
profitability and the carrying value of its oil and gas properties are
substantially dependent upon prevailing prices of, and demand for, oil and gas
and the costs of acquiring, finding, developing and producing reserves.  The
Company's ability to maintain or increase its borrowing capacity, to repay
current or future indebtedness, and to obtain additional capital on favorable
terms is also substantially dependent upon oil and gas prices.  Historically,
the markets for oil and gas have been volatile and are likely to continue to be
volatile in the future.  Prices for oil and gas are subject to wide
fluctuations in response to: (i) relatively minor changes in the supply of, and
demand for, oil and gas; (ii) market uncertainty; and (iii) a variety of
additional factors, all of which are beyond the Company's control.  These
factors include domestic





                                       -10-
<PAGE>   12
and foreign political conditions, the price and availability of domestic and
imported oil and gas, the level of consumer and industrial demand, weather,
domestic and foreign government relations, the price and availability of
alternative fuels and overall economic conditions.   Furthermore, the
marketability of the Company's production depends in part upon the
availability, proximity and capacity of gathering systems, pipelines and
processing facilities.  Volatility in oil and gas prices could affect the
Company's ability to market its production through such systems, pipelines or
facilities.  Substantially all of the Company's gas production is currently
sold to gas marketing firms or end users either on the spot market on a
month-to-month basis at prevailing spot market prices or under long-term
contracts based on current spot market prices.  The Company normally sells its
oil under month-to-month contracts with a variety of purchasers.  Accordingly,
the Company's oil and gas sales expose it to the commodities risks associated
with changes in market prices.  See "Business and Properties -- Marketing of
Production."

         UNCERTAINTY OF ESTIMATES OF RESERVES AND FUTURE NET CASH FLOWS.  This
Prospectus contains estimates of the Company's oil and gas reserves and the
future net cash flows from those reserves, which have been prepared or audited
by certain independent petroleum consultants.  There are numerous uncertainties
inherent in estimating quantities of Proved Reserves of oil and gas and in
projecting future rates of production and the timing of development
expenditures, including many factors beyond the Company's control.  The
estimates in this Prospectus are based on various assumptions, including, for
example, constant oil and gas prices, operating expenses, capital expenditures
and the availability of funds, and, therefore, are inherently imprecise
indications of future net cash flows.  Actual future production, cash flows,
taxes, operating expenses, development expenditures and quantities of
recoverable oil and gas reserves may vary substantially from those assumed in
the estimates.  Any significant variance in these assumptions could materially
affect the estimated quantity and value of reserves set forth in this
Prospectus.  Additionally, the Company's reserves may be subject to downward or
upward revision based upon actual production performance, results of future
development and exploration, prevailing oil and gas prices and other factors,
many of which are beyond the Company's control.  See "Business and Properties
- -- Oil and Gas Reserves."

         The SEC PV-10 of Proved Reserves referred to in this Prospectus should
not be construed as the current market value of the estimated Proved Reserves
of oil and gas attributable to the Company's properties.  In accordance with
applicable requirements of the Securities and Exchange Commission (the
"Commission"), the estimated discounted future net cash flows from Proved
Reserves are generally based on prices and costs as of the date of the
estimate, whereas actual future prices and costs may be materially higher or
lower.  Actual future net cash flows also will be affected by (i) the timing of
both production and related expenses; (ii) changes in consumption levels; and
(iii) governmental regulations or taxation.  In addition, the calculation of
the present value of the future net cash flows using a 10% discount as required
by the Commission is not necessarily the most appropriate discount factor based
on interest rates in effect from time to time and risks associated with the
Company's reserves or the oil and gas industry in general.  Furthermore, the
Company's reserves may be subject to downward or upward revision based upon
actual production, results of future development, supply and demand for oil and
gas, prevailing oil and gas prices and other factors.  See "Business and
Properties -- Oil and Gas Reserves."

         Under full cost accounting, the Company would be required to take a
non-cash charge against earnings to the extent capitalized costs of
acquisition, exploration and development (net of depletion and depreciation),
less deferred income taxes, exceed the SEC PV-10 of its Proved Reserves and the
lower of cost or fair value of unproved properties after income tax effects.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Background."

         OPERATING HAZARDS AND UNINSURED RISKS; PRODUCTION CURTAILMENTS.  The
Company's oil and gas business involves a variety of operating risks,
including, but not limited to, unexpected formations or pressures,
uncontrollable flows of oil, gas, brine or well fluids into the environment
(including groundwater contamination), blowouts, fires, explosions, pollution
and other risks, any of which could result in personal injuries, loss of life,
damage to properties and substantial losses.  Although the Company carries
insurance at levels which it believes are reasonable, it is not fully insured
against all risks.  The Company does not carry business interruption insurance.
Losses and liabilities arising from uninsured or under-insured events could
have a material adverse effect on the financial condition and operations of the
Company.





                                       -11-
<PAGE>   13
         From time to time, due primarily to contract terms, pipeline
interruptions or weather conditions, the producing wells in which the Company
owns an interest have been subject to production curtailments.  The
curtailments range from production being partially restricted to wells being
completely shut-in.  The duration of curtailments varies from a few days to
several months.  In most cases the Company is provided only limited notice as
to when production will be curtailed and the duration of such curtailments.
The Company is not currently experiencing any material curtailment on its
production.

         LAWS AND REGULATIONS.  The Company's operations are affected by
extensive regulation pursuant to various federal, state and local laws and
regulations relating to the exploration for and development, production,
gathering and marketing of oil and gas.  Matters subject to regulation include
discharge permits for drilling operations, drilling and abandonment bonds or
other financial responsibility requirements, reports concerning operations, the
spacing of wells, unitization and pooling of properties, and taxation.  From
time to time, regulatory agencies have imposed price controls and limitations
on production by restricting the rate of flow of oil and gas wells below actual
production capacity in order to conserve supplies of oil and gas.

         Operations of the Company are also subject to numerous environmental
laws, including but not limited to, those governing management of waste,
protection of water, air quality, the discharge of materials into the
environment, and preservation of natural resources.  Non-compliance with
environmental laws and the discharge of oil, gas, or other materials into the
air, soil or water may give rise to liabilities to the government and third
parties, including civil and criminal penalties, and may require the Company to
incur costs to remedy the discharge.  Laws and regulations protecting the
environment have become more stringent in recent years, and may in certain
circumstances impose retroactive, strict, and joint and several liability
rendering entities liable for environmental damage without regard to negligence
or fault.  From time to time the Company has agreed to indemnify sellers of
producing properties from whom the Company has acquired reserves against
certain liabilities for environmental claims associated with such properties.
There can be no assurance that new laws or regulations, or modifications of or
new interpretations of existing laws and regulations, will not increase
substantially the cost of compliance or otherwise adversely affect the
Company's oil and gas operations and financial condition or that material
indemnity claims will not arise against the Company with respect to properties
acquired by or from the Company.  While the Company does not anticipate
incurring material costs in connection with environmental compliance and
remediation, it cannot guarantee that material costs will not be incurred.  See
"Business and Properties -- Regulation."

         COMPETITION.  The Company encounters substantial competition in
acquiring properties, marketing oil and gas, securing trained personnel and
operating its properties.  Many competitors have financial and other resources
that substantially exceed those of the Company.  The Company's competitors in
acquisitions, development, exploration and production include major oil
companies, numerous independents, individual proprietors and others.
Therefore, competitors may be able to pay more for desirable leases and to
evaluate, bid for and purchase a greater number of properties or prospects than
the financial or personnel resources of the Company will permit.  See "Business
and Properties -- Competition."

         DEPENDENCE ON KEY PERSONNEL.   The Company depends to a large extent
on the services of Eugene A. Soltero, the Company's Chairman of the Board and
Chief Executive Officer, James E. Hogue, the President and Chief Operating
Officer of the Company, and Leon A. Romero, Senior Vice President and Chief
Financial Officer.  The loss of the services of any one of these individuals
could have a material adverse effect on the Company's operations.  The Company
has not entered into any employment contracts with any of its executive
officers, nor has it obtained key personnel life insurance.  The Company
believes that its success is also dependent on its ability to continue to
employ and retain skilled technical personnel.  See "Management."

         CONCENTRATION OF VOTING POWER.  Upon the sale of all of the Shares
offered hereby, the Company's executive officers, directors and their
affiliates will beneficially own approximately 14% of the Company's then
outstanding 22,821,557 shares of Common Stock.  Two officers of the Company
have the right under certain Voting Agreements to vote an additional
approximately 2.5 million shares of Common Stock representing approximately 11%
of the outstanding shares of Common Stock.  As a result, officers, directors
and their affiliates will have the ability to exert significant influence over
the business affairs of the Company, including the ability





                                       -12-
<PAGE>   14
to influence the election of directors and result of voting on all matters
requiring stockholder approval.  See "Management -- Voting Agreements" and
"Principal Stockholders."

         CONFLICTS OF INTERESTS.  Certain officers, directors and related
parties have engaged in business transactions with the Company which were not
the result of arms'-length negotiations between independent parties.
Management believes that the terms of these transaction were as favorable to
the Company as those that could have been obtained from unaffiliated parties
under similar circumstances.  All future transactions between the Company and
its affiliates will be on terms no less favorable than could be obtained from
unaffiliated third parties and will be approved by a majority of the
disinterested members of the Board of Directors of the Company.  See "Certain
Relationships and Related Transactions."

         PUBLIC MARKET AND POSSIBLE VOLATILITY OF SECURITIES.  The Common Stock
is traded on the AMEX and "over-the- counter"  in Canada on the Canadian
Dealing Network ("CDN").  The trading price of the Common Stock could be
subject to wide fluctuations in response to quarter-to-quarter variations in
operating results, announcements of drilling results by the Company and other
events or factors.  In addition, the U.S. stock market has from time to time
experienced extreme price and volume fluctuations which have particularly
affected the market price for many companies and which often have been
unrelated to the operating performance of these companies.  These broad market
fluctuations may adversely affect the market price of the Company's securities.
See "Common Stock Price Ranges and Dividends."

         NO DIVIDENDS.  The Company's board of directors presently intends to
retain all of its earnings for the expansion of its business.  The Company
therefore does not anticipate the distribution of cash dividends in the
foreseeable future.  Any future decision of the Company's board of directors to
pay cash dividends will depend, among other factors, upon the Company's
earnings, financial position and cash requirements.  See "Dividend Policy."

         POSSIBLE DILUTION FOR FUTURE SALES OF COMMON STOCK.  Under the
Company's Articles of Amalgamation, the Board of Directors has the authority to
issue an unlimited number of shares of Common Stock and to issue options and
warrants to purchase shares of the Company's Common Stock without stockholder
approval. Under the rules and regulations of the AMEX, stockholder approval
must be obtained if the Company issues more than 20% of its then outstanding
shares.  The issuance of additional shares of Common Stock or the issuance of
stock upon exercise of outstanding options or warrants may result in dilution
of the equity represented by the then outstanding shares of Common Stock held
by other stockholders.  The issuance of additional shares of Common Stock,
while potentially providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of making it
more difficult for a third party to acquire a majority of the outstanding
voting stock of the Company.  The Board could issue large blocks of Common
Stock to fend off unwanted tender offers or hostile takeovers without further
stockholder approval.  See "Description of Securities" and "Shares Eligible for
Future Sale."

         UNLIMITED AVAILABILITY OF PREFERRED STOCK; ANTI-TAKEOVER PROVISIONS.
The Company's board of directors is authorized, without further stockholder
action, to issue an unlimited number of shares of preferred stock in one or
more series and may designate the dividend rate, voting rights and other
rights, preferences and restrictions of each series.  The Board of Directors
has authorized the issuance of up to 2,000,000 shares of 8% Cumulative
Convertible Preferred Stock (the "Convertible Preferred Stock").  There are no
outstanding shares of preferred stock and the Company has no plans to issue any
preferred stock, including the Convertible Preferred Stock.  Any future
preferred stock issuances could have the effect of, among other things,
restricting Common Stock dividends, diluting Common Stock voting power,
impairing Common Stock liquidation rights and delaying or preventing a change
in control of the Company without further action by the stockholders.  See
"Description of Securities -- Preferred Stock."

         SHARES ELIGIBLE FOR FUTURE SALE; POSSIBLE ADVERSE EFFECT ON PUBLIC
MARKET.  Sales of the Shares offered hereby could have an adverse effect on the
market price of the Common Stock.  As of the date of this Prospectus, there will
be approximately 17,073,248 shares of Common Stock outstanding, which amount
does not include 3,941,106 shares which underlie outstanding options and
warrants, including 2,548,309 shares reserved for issuance upon exercise of
outstanding warrants held by certain Selling Stockholders, or up to 3.2 million
shares offered hereby by the Convertible Debenture holders.  Substantially all
of the Company's outstanding shares 





                                       -13-
<PAGE>   15
of Common Stock and the Shares are eligible for public sale without
restrictions, except for shares purchased by affiliates (those controlling or
controlled by or under common control with the Company and generally deemed to
include officers and directors) of the Company. Approximately 665,485 shares of
the Company's Common Stock are "restricted securities" as that term is defined
under Rule 144 promulgated under the Securities Act of 1933, as amended (the
"Securities Act"). Subject to the volume and holding period limitations of Rule
144, 596,638 outstanding shares of Common Stock are eligible for sale under Rule
144 as of the date of this Prospectus. No prediction can be made as to the
effect, if any, that future sales of additional shares of Common Stock or the
availability of such shares for sale under Rule 144, other applicable exemptions
or otherwise will have on the market price of the Common Stock prevailing from
time to time. Sales of substantial amounts of Common Stock in the public market,
or the perception that such sales could occur, could adversely affect prevailing
market prices of the Common Stock. See "Principal Stockholders" and "Shares
Eligible for Future Sale."

     EXCHANGE RATE FLUCTUATIONS.  The Company is exposed to foreign exchange
risks since it has granted stock options and warrants denominated in Canadian
currency while the majority of its expenditures will be in United States
dollars.  Any significant reduction in the value of the Canadian dollar may
decrease the value of funds in United States dollars the Company receives upon
exercise of warrants and options.

     CURRENT PROSPECTUS REQUIRED IN CONNECTION WITH SALE OF SHARES OFFERED
HEREBY.  The Selling Stockholders will be able to sell the Shares offered hereby
only if (i) there is a current prospectus relating to the Shares offered hereby
under an effective registration statement filed with the Commission, and (ii)
such Shares are then qualified for sale or exempt therefrom under applicable
state securities laws of the jurisdictions in which the various Selling
Stockholders reside.  The Company has agreed to use its best efforts to maintain
the effectiveness of the registration of the Shares being offered hereunder for
three years from the date of this Prospectus or such earlier date when all of
the Shares being offered hereunder have been sold or may be sold without volume
or other restrictions pursuant to Rule 144 under the Securities Act, as
determined by counsel to the Company pursuant to a written opinion letter. There
can be no assurance, however, that the Company will be successful in maintaining
a current registration statement. After a registration statement becomes
effective, it may require updating by the filing of a post-effective amendment.
A post-effective amendment is required (i) any time after nine months subsequent
to the effective date when any information contained in the prospectus is over
16 months old, (ii) when facts or events have occurred which represent a
fundamental change in the information contained in the registration statement,
or (iii) when any material change occurs in the information relating to the plan
or distribution of the securities registered by such registration statement. The
Company anticipates that it will be required to file a post-effective amendment
to this Registration Statement from time to time during the next 12 months to
reflect current information regarding the Company.

                    COMMON STOCK PRICE RANGES AND DIVIDENDS

         The Common Stock began trading through the Canadian Dealing Network on
June 24, 1996, under the symbol "CVZC." From June 24, 1996, through February
28, 1998, the following table sets forth the high and low bid information for
the Company's Common Stock in Canadian dollars as reported on the Canadian
Dealing Network.  The information in the table reflects inter-dealer prices,
without retail mark-up, mark-down or commission, and may not necessarily
represent actual transactions.  During this period, the Canadian dollar traded
in the $.69 to $.74 range.  On February 28, 1998 one Canadian dollar was worth
$0.72.

                                DIVIDEND POLICY

         The Company has not previously paid any cash dividends on its Common 
Stock and does not anticipate or contemplate paying dividends on the Common
Stock in the foreseeable future. It is the present intention of management to
utilize all available funds for the development of the Company's business. In
addition, the Company may not pay any dividends on common equity unless and
until all dividend rights on outstanding preferred stock, if any, have been
satisfied. The only other restrictions that limit the ability to pay dividends
on common equity or that are likely to do so in the future, are those
restrictions imposed by law or by certain credit agreements.

                                 CAPITALIZATION

         The following table sets forth the capitalization of the Company as of
December 31, 1997 and on a pro forma basis to reflect the exercise of certain
warrants, including the Debenture Warrants, held by Selling Stockholders,
conversion of the Convertible Debentures and cancellation of 270,000 shares of
Common Stock held in Treasury.  This table should be read in conjunction with

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         The following discussion should be read in conjunction with the
Company's Consolidated Financial Statements and "Selected Historical
Consolidated and Combined Financial Information" and respective notes thereto,
included elsewhere herein. The information below should not be construed to
imply that the results discussed herein will necessarily continue into the
future or that any conclusion reached herein will necessarily be indicative of
actual operating results in the future.  Such discussion represents only the
best present assessment of management of the Company.  Because of the Company's
recent acquisitions and the limited scale of the Company's operations prior to
1996, the results of operations from period to period are not necessarily
comparative.

BACKGROUND

         The Company pursued its acquisition program with the addition of three
properties in fiscal year 1997 and during the six-month period ended December
31, 1997.  Two Texas properties were acquired: the Means Unit in Andrews County
and the Sears Ranch Prospect in Nolan and Fisher Counties.  One Oklahoma
property was also acquired: the N.E.  Alden Field in Caddo County.  The
acquisition of the East Binger Unit, located in Caddo County, Oklahoma, is
scheduled to close on May 31, 1998, subject to certain conditions.  Combined
with the Cheneyboro Field in Navarro County, Texas, these properties provide an
excellent opportunity for future exploration and development drilling.  The
Company also purchased and subsequently resold an interest in the Zama Lake
area in Alberta, Canada, acquired certain horizontal drilling technology and
equipment, and acquired two recently rebuilt well servicing rigs and related
transportation and service equipment.  See "Business and Properties -- Recent
Developments."

         Management has focused on purchasing properties that are strong
candidates for either secondary recovery initiatives or the employment of
specialized drilling and production methods, such as horizontal drilling.  The
Company also believes that its ability to use the Mustang Servicing Companies
to drill both conventional vertical and advanced horizontal wells should lower
the Company's finding and development costs.

         The Company uses the full cost method of accounting for its investment
in oil and gas properties.  Under the full cost method of accounting, all costs
of acquisition, exploration and development of oil and gas reserves are
capitalized into a "full cost pool" as incurred, and properties in the pool are
depleted and charged to operations using the unit-of-production method based on
the ratio of current production to total proved oil and gas reserves.  To the
extent that such capitalized costs (net of accumulated depreciation, depletion
and amortization) less deferred taxes exceed the SEC PV-10 of estimated future
net cash flow from Proved Reserves of oil and gas, discounted at 10%, and the
lower of cost or fair value of unproved properties after income tax effects,
such excess costs are charged to operations.  Once incurred, a write-down of oil
and gas properties is not reversible at a later date even if oil or gas prices
increase.  While the Company has never been required to write-down its asset
base, significant downward revisions of quantity estimates or declines in oil
and gas prices from those in effect on June 30, 1997 which are not offset by
other factors could result in a write-down for impairment of oil and gas
properties.

         Certain statements in this section of the Prospectus and elsewhere
herein constitute "forward-looking statements" within the meaning of the

COMPARISON OF SIX MONTHS ENDED DECEMBER 31, 1997 TO SIX MONTHS ENDED DECEMBER
31, 1996

         During the six months ended December 31, 1997, the Company generated a
net profit after tax of $54,403 on revenue of $1,157,985 as compared with a net
loss of $602,116 on revenue of $41,365 for the six-month period ended December
31, 1996. The improvement results from the first used equipment sales by the
Company's subsidiary, Mustang Oilfield Equipment, oil and gas production
beginning March 1997 from the N.E. Alden Field and August 1997 from the Aspen
properties, oil and gas production beginning November 1997 from the Sears Ranch
Prospect, and continued production from the Company's Cheneyboro properties.

         Oil and gas sales increased 952% from $41,365 for the six months ended
December 31, 1996 to $435,289 for the six months ended December 31, 1997,
reflecting the addition of the Aspen, N.E. Alden and Sears Ranch acquisitions.
Oil and gas production costs increased to $225,925 for the six months ended
December 31, 1997, reflecting the addition of oil and gas properties and
continued remedial work required at the N.E. Alden Field.  The Company did not
have any significant oil and gas production costs for the six-month period
ended December 31, 1996.

         Equipment sales for the six months ended December 31, 1997 were
$713,622 as compared to no sales for the six months ended December 31, 1996.
Equipment purchase and refurbishing expenses were $259,573 for the six-month
period ended December 31, 1997 as compared to zero expenses for the comparable
period ended December 31, 1996.

         General and administrative costs were $413,444 for the six-month period
ended December 31, 1997, a decrease of $489,875 or 54% less than the $903,319
incurred for the six-month period ended December 31, 1996.  A substantial
portion of the decrease was due to an administrative cost reduction program
instituted by management in mid-June 1997. In addition, the Company allocated
approximately $200,000 of general and administrative expenses that were directly
associated with oil and gas acquisition and development activities during the
six months ended December 31, 1997 to oil and gas properties. No such costs were
allocated during the six months ended December 31, 1996 because the Company was
primarily involved in fund raising activities during that time period.

         The Company has provided for income taxes of $18,134 for the six-month
period ended December 31, 1997 as compared to recognition of an income tax
benefit of $295,000 for the six-month period ended December 31, 1996.  This is
directly related to the size of the profit or loss before income taxes during
such periods.

FISCAL YEAR 1997 AS COMPARED TO FISCAL YEAR 1996

         During the fiscal year ended June 30, 1997, the Company incurred a net
loss of $2,006,878 as compared to a loss of $712,360 for fiscal 1996. This 181%
increase in net loss is primarily attributable to increases in general and
administrative expenses.

         General and administrative costs were $2,825,678 in fiscal 1997, an
increase of $1,859,902 or 193% over the $965,776 incurred in fiscal 1996.
Included in 1997 general and administrative expenses is a compensation expense
of $1,286,800 (approximately 46% of total general and administrative expenses)
representing the value of shares and warrants issued to LFC for certain
investor relations services, and approximately $212,000 representing costs
incurred with respect to a public offering of securities which did not
materialize.  The remaining increase in general and administrative expense can
be attributed to the addition of staff and technical personnel during 1997 as
compared to a relatively small staff which was in place for only a part of
1996.  See "Certain Relationships and Related Transactions."

         Oil and gas production costs were $252,272 in 1997 as compared to none
in 1996.  These costs primarily relate to the N.E. Alden Field and particularly
to rehabilitation costs which were not capitalized.  The Company initially
acquired its interest in the N.E. Alden Field in December 1996 for $390,000 of
which $35,000 was paid in December 1996 and $355,000 was paid upon closing on
March 3, 1997.  Oil and gas sales from the N.E. Alden 



                                       -19-
<PAGE>   21
Field in fiscal 1997 were approximately $200,000.  Rehabilitation work on two
wells in the Cheneyboro Field in the fourth quarter of fiscal 1996 resulted in
oil and gas sales of $74,473 during fiscal 1997.

         The Company recognized an income tax benefit of $919,000 in fiscal
1997 compared to $387,000 in fiscal 1996.  This is directly related to the size
of the loss before income taxes during such periods.

         During fiscal 1996, the Company issued 300,000 shares to two former
officers of the Company for services which was recorded at $446,950.  Other
expenses during this period were $657,796 which includes $138,970 in interest
expense and officers and staff compensation.  The loss before income tax
benefit of $387,000 was $1,099,360 during fiscal 1996.

FISCAL YEAR 1996 AS COMPARED TO FISCAL PERIOD 1995

         From February 15, 1995 (inception), to June 30, 1996, the Company
accumulated a deficit of $762,277 after an income tax benefit of $412,000.
During this period, the Company acquired certain oil and gas properties,
completed the amalgamation with Arjon,  issued debentures and notes and sold
stock for cash.  See "Prospectus Summary -- The Company" and "Business and
Properties -- General."

         Legal, audit and accounting fees were $190,053, which represents 17%
of the net loss before tax through June 30, 1996.

         Management fees of $82,840 and salaries of $163,309, for a total of
$246,149, represent 22% of the net loss before tax through June 30, 1996.  The
Company paid management fees of $10,000 per month from its inception to July
31, 1995, and $20,000 per month from August 1, 1995 to March 31, 1996, for the
full-time services of Eugene A. Soltero, Chairman of the Board and Chief
Executive Officer, and James E. Hogue, President and Chief Operating Officer.
Effective April 1, 1996, each of these officers received a salary of $10,000
per month.  A third officer earned $10,000 per month from August 1, 1995.  A
fourth officer earned $10,000 per month from May 1, 1996.  See "Management --
Executive Compensation" and "Certain Relationships and Related Transactions."

         Management fees and salaries totaling $194, 951 from inception through
June 30, 1996, were capitalized into oil and gas properties and are not
included in the accumulated deficit as of that date.  These costs represent the
estimated portion of the compensation directly attributable to acquisition of
the properties in the Cheneyboro Field and related development activities.  See
"Business and Properties -- Description of Properties."

LIQUIDITY AND CAPITAL RESOURCES

         During the six months ended December 31, 1997, the Company generated
$187,000 in cash from operating activities, primarily from earnings before non
cash charges. Cash of $7,000,000 was used in investing activities in additions
to oil and gas properties, oilfield equipment and restricted cash. Cash of
approximately $6,600,000 was generated primarily from sale of stock and exercise
of warrants and from the issuance of the Convertible Debentures.

         During the year ended June 30, 1997, the Company used cash in operating
activities of approximately $1,200,000, resulting from a net loss of $2,006,000
reduced primarily by non cash charges against earnings. The Company generated
cash from financing activities during the year ended June 30, 1997 of
approximately $2,000,000 from the sale of stock, exercise of warrants and
issuance of notes payable. Approximately $950,000 of cash was used in the year
ended June 30, 1997 in investing activities to acquire property and equipment.
During the year ended June 30, 1996, the Company used $270,000 cash in operating
activities, generated $1,861,000 cash in financing activities and used
approximately, $800,000 cash in investing activities. The sources and uses of
the cash were similar in 1996 as to that described above for 1997.

         As of December 31, 1997, the Company had working capital of
$2,619,225, which includes $2,570,280 of restricted cash which may be used for
working capital, acquisition of oil and gas properties, oilfield equipment and
development of properties.  The restricted cash represents the remaining and
unutilized proceeds from the sale of Convertible Debentures.  Management
estimates that aggregate capital expenditures of approximately $6 million 


                                       -20-
<PAGE>   22
will be spent during the remainder of fiscal 1998 to acquire and develop oil and
gas reserves.  The Company intends to finance acquisition and development of oil
and gas properties with the proceeds from private placements of debt and equity
securities, proceeds from the exercise of outstanding warrants, traditional bank
debt and institutional mezzanine reserves based financing.  No assurance can be
given that the Company will be successful in these efforts.  See "Description of
Securities -- Convertible Debentures."

         Since July 1, 1997, the Company has raised $4,320,000 from the sale of
Convertible Debentures, approximately $454,500 through the sale of 272,700
shares of its Common Stock and warrants to purchase 322,700 shares, exercisable
at $2.08 per share until April 3, 2002, in a private placement and issued
$125,000 of 15% two-year notes.  In addition, from July 1, 1997 through
February 28, 1998, warrants to purchase approximately 1,677,609 shares of
Common Stock had been exercised for proceeds of $2,920,122.  See "Business and
Properties -- Recent Developments; Sale of Convertible Debentures" and
"Description of Securities -- Warrants; WPM Warrants."

         The Convertible Debentures require payments of interest only, at 7%,
until December 31, 2001, at which time principal is due in full.  Interest
payments may be made in shares of the Company's Common Stock, at the Company's
election.  The Debentures may be converted, at the option of the holders, at the
lesser of $2.70 per share or 90% of the average of the three lowest closing bid
prices during the ten trading days prior to the notice of conversion.  If the
conversion price is below $1.80 per share, no more than 10% of the Debentures of
any holder may be converted in any 30-day period. The Company will record an
expense for the difference between the conversion price and the market price of
the Company's Common Stock at the time Debentures become eligible for
conversion.

         The Company expects that its capital expenditure requirements will be
met as follows:

         -       through the proceeds received from the exercise of outstanding
                 warrants;
         -       institutional reserves based development mezzanine loans;
         -       traditional commercial bank asset lending;
         -       private sales of securities; and
         -       revenues from operations.

         Management believes a combination of the above sources of capital will
provide the necessary liquidity to operate the Company over the next 12 months.
No assurance can be given that any additional financing will be available to
the Company on acceptable terms, if at all.  The inability to obtain additional
financing would have a material adverse effect on the Company, including
requiring the Company to curtail significantly development of its properties.
Any financing may involve substantial dilution to the interests of the
Company's then existing stockholders.

INFLATION AND CHANGES IN PRICES

         During recent years, the Company believes that there has been some
inflation in oil and gas prices with moderate increases in property acquisition
and development costs.  The results of operations and cash flow of the Company
have been, and will continue to be, affected to a certain extent by the
volatility in oil and gas prices.  Should the Company experience a significant
increase in oil and gas prices that is sustained over a prolonged period, it
would expect that there would also be a corresponding increase in oil and gas
finding costs, lease acquisition costs, and operating expenses.  The Company
has not engaged in any hedging activities.

         The Company markets oil and gas for its own account, which exposes the
Company to the attendant commodities risk.  Substantially all of the Company's
gas production is currently sold to gas marketing firms or end users either on
the spot market on a month-to-month basis at prevailing spot market prices or
under long-term contracts based on current spot market prices.  The Company
normally sells its oil under month-to-month contracts with a variety of
purchasers.

YEAR 2000 MODIFICATIONS

         The Company is currently reviewing its computer systems in order to
evaluate necessary modifications for the year 2000.  The Company does not
currently anticipate that it will incur material expenditures to complete any
such modifications.

OTHER MATTERS

         In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128, Earnings Per Share ("SFAS
128").  SFAS 128 requires companies with complex capital structures that have
publicly held common stock or common stock equivalents to present both basic
and diluted earnings per share ("EPS") on the face of the income statement.
The presentation of basic EPS replaces the presentation of primary EPS
currently required by Accounting Principles Board Opinion No. 15 ("APB No.
15").  Basic EPS is calculated as income available to common stockholders
divided by the weighted average number of common shares outstanding during the
period.  Diluted EPS is calculated using the "if converted" method for
convertible securities and the treasury stock method for options and warrants
as prescribed by APB No. 15.  This statement is effective for financial
statements issued for interim and annual periods ending after December 15,
1997.  The Company adopted SFAS 128 as of December 31, 1997 for the period
ended December 31, 1997 and all prior periods.  The adoption of SFAS 128 has
not had a significant impact on the Company's reported EPS to date.

         In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 129, Disclosures of Information
About Capital Structure ("SFAS 129") which establishes standards for disclosing
information about an entity's capital structure.  The disclosures are not
expect to have a significant impact on the consolidated financial statements of
the Company.  SFAS 129 is effective for financial statements ending after 
December 15, 1997.

         In June 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income ("SFAS 130") which established standards for reporting and displaying
comprehensive income and its components (revenues, expenses, gains and losses)
in a full set of general purpose financial statements.  SFAS 130 requires that
all items that are required to be recognized under accounting standards as
components of comprehensive income be reported in a financial statement that is
displayed with the same prominence as other financial statements.  SFAS 130 is
effective for years beginning after December 15, 1997.  The Company does not
anticipate a material impact to its consolidated financial statements upon
adoption of this standard.

         In June 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 131, Disclosures About Segments
of an Enterprise and Related Information ("SFAS 131") which establishes
standards for the way public business enterprises are to report information
about operating segments in annual financial statements and requires those
enterprises to report selected information about operating segments in interim
financial reports issued to shareholders.  It also establishes the related
disclosures about products and services, geographic areas and major customers.
SFAS 131 replaces the "industry segment" concept of Financial Accounting
Standard No. 14 with a "management approach" concept as the basis for
identifying reportable segments.  SFAS 131 is effective for financial
statements for periods beginning after December 15, 1997.  The Company expects
additional disclosures will be required, but otherwise does not anticipate a
material impact to its consolidated financial statements upon adoption of this
standard.

                            BUSINESS AND PROPERTIES

GENERAL

         The Company, through its subsidiaries, is engaged in the exploration
and development, acquisition and operation of oil and gas properties with a
geographic focus in major oil and gas producing regions in the United States.
The Company was incorporated in the Province of Ontario, Canada, originally as
Cotton Valley Energy Limited, on February 15, 1995.  From its inception through
June 30, 1997, the Company was engaged principally in organization and
capitalization activities and did not generate material revenues from
operations.

         On June 30, 1995 in a one-for-one share and warrant exchange, the
Company acquired all the issued and outstanding shares of CV Energy.  The
Company intends to conduct most of its acquisition, exploration and development
of oil and gas properties through CV Energy, which currently owns properties in
Texas and an option to participate in an offshore California exploration
project.

         As a result of the Arjon amalgamation, which was completed on June 14,
1996, the Company's name was changed to Cotton Valley Resources Corporation and
its shares of Common Stock began trading through the Canadian Dealing Network
("CDN").  Arjon was a public Canadian company formed more than 50 years ago to
operate a gold mine.  At the time of the amalgamation, Arjon had not engaged in
business for more than 25 years, it had no material liabilities, and its only
asset was a Cotton Valley Energy Limited debenture in the amount of $146,300.
The stockholders of Arjon received 686,551 shares of Common Stock in the
amalgamation.

          On April 30, 1996, the Company organized CV Operating to operate the
Company's oil and gas properties.  The Company on February 25, 1997, organized
CVEI to acquire and operate the N.E. Alden Field properties in Caddo County,
Oklahoma.  CVEI commenced operations on March 3, 1997.  Aspen was an inactive
subsidiary of the Company formed on May 1, 1996, which was used to accommodate
the merger of Old Aspen into Aspen, a wholly-owned subsidiary of the Company,
which was completed on July 31, 1997.  The principal asset of Old Aspen was its
interest in the Means Unit in Andrews County, Texas.

         On February 9, 1998, the Company continued into Canada's Yukon
Territory.  Under the law of the Yukon Territory, the Company's board of
directors need not be comprised of a majority of Canadian residents as
previously required under Ontario law.  Since the Company's principal offices,
management and properties are located in the United States, management believes
it is advantageous to have a majority of the Company's directors be residents
of the United States.  The Company may in the future continue from the Yukon
Territory to the State of Wyoming.  Management believes there are no
significant differences in corporate law concerning material stockholder rights
between the Province of Ontario, the Yukon Territory and the State of Wyoming.
The Company, at its annual meeting held December 10, 1996, obtained stockholder
approval for the continuance into the Yukon Territory.

MUSTANG SERVICE COMPANIES

         In addition to CV Energy, CV Operating, CVEI and Aspen, the Company
recently organized the Mustang Service Companies. The Mustang Service Companies,
CV Operating, CV Energy, CVEI and Aspen are currently wholly-owned Company
subsidiaries.  However, the Company has agreed to sell for nominal cost up to
15% of the common stock of the Mustang Service Companies to certain employees
and officers of the Company, including Eugene A. Soltero, Chairman of the Board,
Chief Executive Officer, and James E. Hogue, President and Chief Operating
Officer. The total value of the 15% interest to be received by these individuals
is not expected to be significant at the time of receipt based on the net book
value of the companies.

         The Company believes that the current demand in the petroleum industry
for drilling and production equipment and services in general, and particularly
horizontal drilling equipment, provides the Company with an 



                                       -23-
<PAGE>   25
opportunity to increase revenues and cash flow through the acquisition and
refurbishment of used oil field equipment and the use of well servicing rigs and
related equipment.  The Company has augmented its property acquisition and
development strategy with the addition of the Mustang Service Companies which
the Company believes can provide timely, quality services at competitive costs
as well as providing the Company with the capabilities to perform workovers,
horizontal drilling, and most significantly, the equipment and personnel
necessary for the Company to conduct its exploration and development activities.

CURRENT OPERATIONS

         Since January 1997, the Company has acquired oil and gas properties in
Oklahoma and Texas, certain horizontal drilling technology and equipment, and
two workover rigs and related equipment.  The Company also purchased and sold a
Canadian property.  To finance the acquisitions, the Company has raised capital
through the private sale of shares of Common Stock and warrants, the issuance
of debt instruments, including $4,320,000 of Convertible Debentures and from
July 1, 1997 through February 28, 1998, the exercise of options and warrants to
purchase approximately 1,677,609 shares of Common Stock for proceeds of
$2,920,122.  See "Business and Properties  -- Recent Developments."

         For the fiscal year ended June 30, 1997 and the six-month period ended
December 31, 1997, the Company recorded revenues of $276,230 and $1,157,985,
respectively, and had a net loss of $2,006,878 and a net profit of $54,403,
respectively.  As of December 31, 1997, the Company had an accumulated deficit
of $2,714,752 and working capital of $2,619,225.  The Company does not have a
bank line of credit.  The Company has funded its operating losses, acquisitions
and expansion costs primarily through a combination of private offerings of
debt and equity securities, including the issuance of the Convertible
Debentures.  See "Selected Historical Consolidated and Combined Financial
Information" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

BUSINESS STRATEGY

         The Company's current business strategy is to (i) continue to increase
reserves, production and cash flows by acquiring properties, or companies with
properties, with development opportunities, (ii) develop existing reserves
through low risk developmental drilling or recompletion programs, (iii)
concentrate on development activities within a limited number of core areas;
(iv) acquire and refurbish used oil field equipment for use in development
activities and for resale; and (v) provide well servicing for the Company's and
other wells.  Although the Company continuously is seeking acquisitions of
reserves and oil field equipment, there can be no assurance that the Company
will be able to identify and acquire reserves or oil field equipment upon terms
favorable to the Company or obtain the necessary financing on favorable terms.
See "Business and Properties."

         The following are key elements of the Company's strategy:

         o       EXPLOITATION AND DEVELOPMENT OF EXISTING PROPERTIES.  The
                 Company has a significant inventory of exploitation projects,
                 including development drilling, workovers and recompletions.
                 The Company intends to maximize the value of its properties
                 through development activities including in-fill drilling,
                 waterflooding and other enhanced recovery techniques.

         o       MANAGEMENT OF OPERATING COSTS.  The Company emphasizes strict
                 cost controls in all aspects of its business and intends to
                 operate its properties wherever possible.  By operating its
                 properties, the Company believes it will be able to control
                 direct operating and drilling costs as well as to manage the
                 timing of development and exploration activities.

         o       PROPERTY ACQUISITIONS.  Although the Company has a significant
                 inventory of exploitation and development opportunities, it
                 continues to pursue strategic acquisitions which fit its
                 objectives of having Proved Reserves with development
                 potential and operating control.

         The success of the Company in maintaining positive working capital and
obtaining the necessary capital resources to fund future costs associated with
its operations and expansion plans is dependent upon the Company's 



                                       -24-
<PAGE>   26
ability to (i) increase revenues through acquisitions and recovery of proved
producing and proved developed non- producing reserves; (ii) implement stringent
costs controls at the corporate administrative office and in field operations;
(iii) convert Convertible Debentures to equity; (iv) obtain the exercise of
outstanding warrants; and (v) obtain asset based commercial financing.  However,
even if the Company achieves some success with its plans to maintain or increase
its working capital, there can be no assurance that it will be able to generate
sufficient revenues to achieve significant profitable operations or fund its
expansion and acquisition plans.

         ASPEN ACQUISITION.  Effective June 30, 1997, the Company, through its
wholly-owned subsidiary, Aspen, acquired Old Aspen, whose principal asset
consisted of a 100% working interest in the Means Unit in Andrews County,
Texas.  The purchase price consisted of $200,000 cash, $300,000 of short-term
notes, 2,511,317 shares of Common Stock, of which 270,000 shares were returned
to the Company by the Old Aspen shareholders in settlement of notes payable to
Old Aspen in the amount of $425,000.  The acquisition also included various
interests, having an aggregate value of less than $500,000, in two wells in
Utah, which were subsequently sold by the Company for $200,000, two wells in
Latimer County, Oklahoma, one well in Harrison County, Texas and several
shallow wells in Gregg County, Texas.  See "-- Description of Properties; Means
Unit" and "Agreements with Selling Stockholders -- Aspen Acquisition."

         SEARS RANCH PROSPECT.   In October, 1997, the Company, through its
subsidiary, CV Energy, completed the acquisition of a 100% working interest in
approximately 6,200 acres in the Sears Ranch area of Nolan and Fisher Counties,
Texas (the "Sears Ranch Prospect") for $400,000 cash.  Other consideration
received by the Company included pooling rights, existing contracts related to
the Sears Ranch Prospect and all personal property (including equipment)
located on or used in connection with the Sears Ranch Prospect.  The primary
purpose of this acquisition was to acquire oil field equipment, including
pumpjacks, tank batteries, injection pumps, separators, tubing and casing.

         The Sears Ranch Prospect has been productive in the Odem Lime
formation, with cumulative production of approximately eight million barrels.
Attempts to waterflood this property by predecessor operators have been
unsuccessful.  According to reports by the Company's independent consultants,
the Sears Ranch Prospect is an excellent candidate for redevelopment using
horizontal drilling.  In February 1998, the Company began testing this prospect
as a horizontal drilling prospect in the Odem Lime formation.  There can be no
assurance that the Company can economically develop any remaining reserves from
the Sears Ranch Prospect through either horizontal or vertical drilling.
Accordingly, the Company did not attribute any value to reserves in this
prospect in making this acquisition.

         M&M ACQUISITION.  Effective November 5, 1997, the Company, through its
subsidiary, Mustang Horizontal, acquired certain horizontal drilling technology
and equipment from M&M Directional Drilling Consultants ("M&M").  As partial
consideration for the purchase, the Company issued warrants to purchase 60,000
shares of Common Stock (the "Mustang Warrants") to M&M.  The Mustang Warrants
are exercisable at any time at an exercise price of $3.50 per share until
December 31, 2000.  In addition, the Company paid M&M $550,000 cash for the
horizontal drilling technology and equipment.  See "Description of Securities
- -- Warrants; Mustang Warrants."

         EQUIPMENT ACQUISITION.  On December 30, 1997, the Company, through its
subsidiary, Mustang Well Servicing, acquired from three institutional lenders,
who had obtained the equipment through a foreclosure proceeding, two recently
rebuilt well servicing rigs and related transportation and service equipment
(the "Equipment") for $1 million in cash and issuance of $220,000 of the
Convertible Debentures described below.  The Equipment was tooled out at Mustang
Well Servicing's facilities at Odessa, Texas and began workover and horizontal
drilling re-entry operations in February 1998 on the Company's Means Unit in
Andrews County, Texas and Sears Ranch Prospect in Nolan and Fisher Counties,
Texas.

         SALE OF CONVERTIBLE DEBENTURES.  On December 30, 1997, the Company
completed the private placement of $4,320,000 of its 7% Secured Convertible
Debentures ("Convertible Debentures") to a group of eight institutional
investment firms led by a Fort Worth, Texas institutional energy investor.
Approximately $1 million 



                                       -25-
<PAGE>   27
of the cash proceeds and $220,000 of Convertible Debentures were used to
purchase the Equipment.  The remaining funds will be used for the acquisition
and development of oil and gas properties and purchase of oil field equipment.

         The Convertible Debentures are due December 31, 2001 and are secured
by the Equipment and other assets of the Company, including the unutilized
proceeds from the sale of the Convertible Debentures (the "Restricted Cash").
At December 31, 1997, the Company had approximately $2.5 million of Restricted
Cash.  The Convertible Debentures are convertible into a minimum of
approximately 1.6 million shares of the Common Stock and a minimum of 400,000
warrants ("Debenture Warrants"), subject to adjustment upon certain events,
exercisable at prices related to the market price at the time of conversion,
with limits on rights to convert if the conversion price of the Common Stock
falls below a floor price of $1.80 per share (the "Floor Price").  The
conversion price is the lesser of $2.70 per share or 90% of the average of the
three lowest closing bid prices during the ten trading days prior to the notice
of conversion.  During any thirty-day period, any investor may not tender for
conversion more than 10% of his originally purchased Convertible Debentures at
a conversion price less than the Floor Price.  The Company may elect to redeem
(for a 10% premium) any Convertible Debentures tendered for conversion at any
price below the Floor Price.

         In addition to the usual and customary covenants contained in
convertible debenture agreements of this nature, the Company is required to
reserve shares of Common Stock in an amount not less than 200% of the number of
shares of Common Stock that would be issuable upon conversion in full of the
Convertible Debentures and full exercise of the Debenture Warrants granted
thereunder.  In furtherance of this covenant, the Company is required to seek
stockholder approval of an increase in the Company's authorized shares if
necessary to maintain such reserves.  Furthermore, any holder of Convertible
Debentures shall not be permitted to convert its Convertible Debentures or
exercise its Debenture Warrants to the extent that such conversion or exercise
would result in a beneficial ownership in the Company in excess of 4.999%.  The
Convertible Debenture holders have a right of first refusal for future
financing of the Company under certain conditions.  The Company has listed an
additional 3.2 million shares of its Common Stock on AMEX for the shares
underlying the Convertible Debentures and shares to be issued upon exercise of
the Debenture Warrants.  Although the Company's Registration Statement, of
which this Prospectus is a part, includes 3.2 million shares which the Company
currently believes will provide sufficient shares upon the conversion of the
Convertible Debentures and upon exercise of all the Debenture Warrants, the
Company has reserved for issuance a total of up to 4.8 million shares of its
Common Stock to be issued, if necessary, upon conversion of the Convertible
Debentures and up to 1.2 million shares to be issued, if necessary, upon
exercise of the Debenture Warrants.  See "Description of Securities --
Convertible Debentures," "Selling Stockholders" and "Agreements with Selling
Stockholders."

         ZAMA LAKE PROPERTY PURCHASE AND SALE.  In January 1998, the Company
completed the purchase of substantially all of the oil and gas interests in the
Zama Lake area in Alberta, Canada (the "Zama Property") owned by a Canadian
independent oil and gas producer.  The purchase price was $6.9 million.
Immediately following the purchase of the Zama Property, the Company sold all
of its interests to Phillips Petroleum Resources, Ltd. and certain of its
affiliates for $7.5 million.  

         The Zama Property consists of a total of 23,400 gross acres (11,672
net acres) of oil and gas leases and 42 producing wells in northwest Alberta
approximately 55 miles northeast of Rainbow Lake.  At the time of this
transaction, the Zama Property's production net to the interests acquired
averaged approximately 270 Bbls/D of oil, 6 MMcf/D of gas and 30 Bbls/D of
natural gas liquids.

         PURCHASE OF EAST BINGER UNIT, CADDO COUNTY, OKLAHOMA.  On January 14,
1998, CVEI, a subsidiary of the Company, and Phillips Petroleum Company
("Phillips") entered into an agreement for the purchase by CVEI of all of
Phillips' interests in certain oil and gas leases (the "Leases"), including the
wells, equipment and personal property located on the Leases, in the East
Binger Unit, Caddo County, Oklahoma ("East Binger Unit") for $4,000,000.
Closing of the transaction is subject to CVEI obtaining financing for the
purchase price and is currently scheduled for May 31, 1998.  The completion of
the transaction is further subject to title examinations and other conditions.
If CVEI meets all of the conditions to closing and is willing to waive any
conditions of closing applicable to Phillips which Phillips has not met, and
Phillips fails or refuses to close, CVEI will be entitled





                                       -26-
<PAGE>   28
to liquidated damages in the amount of $1,000,000.  Phillips owns a 23.358712%
working interest (18.358712% net revenue interest plus .020836% overriding
royalty interest) in the East Binger Unit.

         The Company is currently negotiating with several financial
institutions and private investors for the financing for the East Binger Unit
purchase.  Although the Company believes it will be able to obtain the
necessary financing within the required time schedule, there can be no
assurance that the Company will be able to timely obtain the necessary funds or
that such financing will be available on favorable terms to the Company.
Further, there is no assurance that all of the conditions necessary for closing
will be met by either Phillips or CVEI.

         Management believes the East Binger Unit acquisition will provide
increased cash flow and allow the Company to economically utilize personnel and
equipment which are already in place for the operation of the Company's
existing Oklahoma and Texas properties.  The East Binger Unit is an 80-well
enhanced oil recovery project which the Company's consulting engineers have
estimated contains reserves ranging from 1.0 million barrels oil equivalent
("BOE") of light sweet crude oil, natural gas and natural gas liquids to a
maximum of 2.5 million BOE.  The Company estimates the present value of future
net revenues (discounted at 10%) could range from net $4 million to $10
million, depending upon production decline rates, future percentages recovery
rates and oil prices.

         The East Binger Unit was the first commercially successful application
of nitrogen injection pressure maintenance for enhanced oil recovery and has
been operating since the early 1980s.  With 56 producing wells and 25 injection
wells, a cryogenic air separation plan and 20 million cubic feet per day
compression capacity, the East Binger Unit currently produces approximately
2,000 BOE daily.  The Company's interest in the East Binger Unit will be
approximately 23.4% working interest in the 13,000-acre unit and nitrogen
plant.  The Company will also obtain all of Phillip's interest in the other
shallower zones in the approximately 3,000 net acres of oil and gas leases
contributed by Phillips to the East Binger Unit.

DESCRIPTION OF PROPERTIES

         CHENEYBORO FIELD.  The Company owns approximately 6,000 net acres of
producing and non-producing oil and gas leases (with rights of first refusal to
acquire additional leases) in the Cheneyboro Field of Navarro County, Texas
(the "Cheneyboro Field").  The Company has entered into an Area of Mutual
Interest ("AMI") Agreement with a number of unaffiliated parties covering
approximately 33,000 acres in and around the Cheneyboro Field.  The Company has
the right to acquire up to a 75% working interest in any new lease acquired by
any of the other parties to the AMI Agreement.

         The Cheneyboro Field is located 17 miles southeast of Corsicana,
Texas, in Navarro County.  This field is productive in the Cotton Valley
Limestone formation (also called the "Cotton Valley Lime") at a vertical depth
of approximately 9,500 feet.  Field development continued following the initial
discovery in 1978 into the early 1980s.  Between 1978 and 1987, marginal wells
were drilled defining the limits of the field.  Approximately 30 interior
additional vertical wells in the Cheneyboro Field produced approximately 2.7
million Bbls of oil, representing an average of approximately 90,000 Bbls per
well.  Some of the vertical wells have produced over 200,000 Bbls, indicating
better drainage where the wells penetrated the fracture system.  In 1989,
approximately 12,000 acres of this field was expropriated and several producing
wells were plugged in order to build Richland/Chambers Creek Reservoir, a water
supply reservoir for the City of Fort Worth, Texas.  See "-- Oil and Gas
Reserves."

         The Company believes that horizontal drilling techniques will lead to
higher initial rates and better recovery efficiencies in this field than  those
experienced in the original vertical well completions.  Since much of the field
is under water, some directional drilling from the shoreline is anticipated.
Based on analogy to horizontal drilling in fractured limestone reservoirs in
other areas, increased productive capacity and ultimate reserves are
anticipated relative to historical, vertical per well averages.

         The Company is unaware of any regulatory restrictions on drilling near
the reservoir.  The Company will build the normal retaining walls around its
drilling and storage sites to prevent oil spills from spreading.  The





                                       -27-
<PAGE>   29
Company intends drilling to a depth of approximately 9,500 feet and does not
anticipate any special risks associated with drilling near a reservoir.  See
"-- Regulation; Environmental Regulation."

         MEANS UNIT.  The Means (Queen Sand) Unit is located in Northern
Andrews County, Texas (the "Means Unit") and consists of approximately 2,096
net acres on four separate leases with 16 producing wells and 52 infield proved
undeveloped locations.  The Company's consulting engineers estimate proved
undeveloped reserves between 1.5 and 2.8 million Bbls of oil and between 0.5
and 1.0 MMcf of natural gas.  The Means Unit was originally part of an
11,500-acre unit owned and operated by a major oil company.  Initial production
begin in the 1950's and the waterflood program was initiated in the 1960's.
The waterflood project was abandoned before 50% of the designed water volume
was injected, when concentration was shifted to CO2 flooding of zones below the
Queen Sand formation.   Currently there are 11 Queen Sand waterflood units near
the Company's Means Unit.  The Company believes the Means Unit has better
reservoir properties than the average of the adjoining ten units, but only half
as much oil has been produced as compared with the original oil in place.  This
is mostly due to the other units having been more densely and completely
developed.  The Company has designed an increased density redevelopment program
consisting of reworking oil wells, drilling new wells and installing
high-volume water injection and oil producing equipment.

         An engineering report, as of June  30, 1997, prepared by Ryder Scott
Company for the Company estimates that the Means Unit contains net proved
undeveloped reserves of 1.5 million Bbls of oil and 0.5 Bcf of gas.  The
Company estimates that it will require a capital investment of approximately
$7.5 million to develop this property.  See "-- Oil and Gas Reserves."

         N.E. ALDEN FIELD.   On March 3, 1997, the Company purchased all of the
interests held by the Homestake Company and certain other parties in the N.E.
Alden Field, Caddo County, Oklahoma.  Subsequently, the Company acquired
additional interests from other parties.  The properties, consisting of
approximately 550 net acres of oil and gas leases, 11 producing oil and gas
wells, three injection wells and two shut in wells, contain proved developed and
undeveloped net reserves of approximately 515,515 Bbl of oil and 5.2 Bcf of gas.
Working interests in the wells ranges from 50% to 100% and the net revenue
interest is at least 75% of the respective working interests.  As a result of
recent workover activity in the Hunton Formation, the Company expects certain
reserves currently classified as probable will be reclassified as proved
reserves.

         Located approximately 65 miles southwest of Oklahoma City, Oklahoma,
the field was discovered in 1956  and initially tested for 771 barrels of oil
and 608 Mcf of gas per day from the Bromide formation at a depth of
approximately 9,300 feet.  Since the discovery, the Bromide has been developed
and is now a unitized water flood consisting of four producing wells and three
water injection wells.  The remaining wells have been completed in other zones
above and below the Bromide.  Gas from the field is transported through a
gathering system and a one-mile pipeline owned by the Company.

         In addition to the current production, there are also potential zones
either behind existing wells, or reachable by deepening existing well bores.
During 1997, the Company completed a number of workovers of the existing wells
which improved production from existing zones and opened new zones for
additional production and reserves.  During fiscal 1998, the Company expects to
deepen at least one well to develop proved reserves in the Arbuckle Formation
offsetting a well which had initial flow rates of approximately 7,000 MCF of
gas per day.  The Company's total investment in this property, including
acquisition costs and workover expenditures, has been approximately $800,000 as
of February 28, 1998.

         OPTION TO ACQUIRE INTEREST IN SWORD UNIT.  The Company has entered
into option agreements to acquire a 51.8% working interest in the Sword Unit,
Offshore Santa Barbara County, California (the "Sword Unit") for $8 million.
The Company is also required to participate in a $4,000,000 letter of credit
related to the abandonment of two existing wells if it exercises the option.
The Sword Unit option expires on January 31, 1999.  Although the Company
believes that it will be able to form a syndicate to fund the exercise of the
option prior to its expiration.  There can be no assurance that the Company
will be able to successfully form such a syndicate or obtain the necessary
funds to exercise the option.





                                       -28-
<PAGE>   30
         The Sword Unit is located 10 miles off Point Conception, Santa Barbara
County, California, 800 to 1,800 feet underwater, at the juncture of the Santa
Barbara Channel and the offshore Santa Maria Basin.  Two successful wells have
been drilled and tested on the unit.  Both of these wells tested Monterey zones
at high rates.  A 3-D seismic survey has been shot, delineating a large
anticline.  The Upper Miocene fractured Monterey pay is 800 feet thick at the
crest and 1,200 feet thick on the flanks and is encountered at approximately
7,000 feet.  Proved recoverable reserves in the Sword Unit are estimated to be
314 million Bbls of oil and 397 million Mcf of gas.

         The regulatory framework within which the Company will develop the
Sword Field consists of: (i) Federal Offshore Lease and Administration,
including approvals of the development plan of the property; (ii) a Federally-
mandated environmental impact statement; (iii) State of California regulations
with respect of transport of oil and gas through state waters and the air
emissions from offshore and onshore facilities; and (iv) Santa Barbara County
regulations with respect to the construction and operation of onshore
facilities.  Permits and approvals from all three government levels will be
required to complete the development of the field and bring it into operation.

         The first three miles off the shore of the coastline are administered
by respective state agencies and are known as "State Waters".  Within State
Waters offshore Santa Barbara County, the State of California regulates oil and
gas leases, drilling, and the installation of permanent and temporary
production facilities.  Because the Sword Unit is located outside and beyond
the State Waters in the Outer Continental Shelf ("OCS"), leasing and drilling
at the Sword Unit are not regulated by the State of California.  However, to
the extent that the production from the Sword Unit would be transported to a
shore side facility from the field through the State Waters, the Company's
pipeline (or other transportation facilities) would be subject to California
State regulations.  Construction and operation of the pipeline would require
permits from the State.  State regulations also govern the construction and
operations of shore side facilities such as terminals, pumping stations, water
separation facilities, and water disposal, all of which require a comprehensive
permitting process.

         Santa Barbara County, through its Board of Supervisors, also has a
significant impact on the method and timing of any offshore field development
through its concurrent regulation of the construction and operation of shore
side facilities.

         Due to political opposition, the Federal Government has not issued new
OCS leases in the Santa Barbara area within the past ten years and is unlikely
to do so in the near future.  This means that any infrastructure for common use
by the different operators of existing leases in the Santa Barbara OCS will
have to rely solely on what is already in place and what would be built to
accommodate a limited number of now known, but undeveloped, properties and
cannot take into account the future growth of infrastructure from new
discoveries and a high level of exploratory activity.  For these reasons, the
development of any existing property in the OCS, including the Sword Unit,
would be much more expensive and take longer than similar projects located in a
mature and still growing offshore province such as the U.S.  Gulf Coast.

         Thus, the value of the proved undeveloped reserves, if acquired by the
Company upon exercise of the option, will be significantly lower than if the
same reserves were located onshore in a less environmentally sensitive area of
the United States that could be developed sooner.  Although oil sale prices are
not currently regulated, they have been in the past and could be regulated in
the future.  The rate of production could be affected by Minerals Management
Service regulations, which could also lower the value of the property.

         The Company currently does not have the capital, personnel or
technical resources to exploit the Sword Unit leases successfully, assuming
exercise of the option.  In order to effectively develop the Sword Unit leases
at the 51.8% working interest level, the Company would require substantial
capital.  The Company's current strategy for development of the Sword Unit is
to retain only that portion of the 51.8% it believes it will be able to
financially and technically support over the next five years (currently
estimated at 11.8%) and seek joint venture partners to participate in and
operate the remainder.  Due to regulation and environmental compliance, many
large independent oil and gas producers have avoided the Sword Unit area, and
the task of locating appropriate joint venture partners will be difficult.

TITLE OF PROPERTIES

          The Company follows industry practice when acquiring undeveloped
properties on minimal title investigation.  A title opinion is obtained before
drilling begins on the properties.  The Company has title opinions for a
majority of its properties .  The Company's properties are subject to royalty
interests, liens incident to operating agreements, liens for current taxes and
other burdens that the Company believes do not materially interfere with their
use or value.  The Company may incur additional expenses in obtaining titles or
doing remedial work on the titles, but in the opinion of management these
expenses would not be material.

DEVELOPMENT AND EXPLORATION ACTIVITIES

         OVERVIEW.  The Company presently intends to focus its exploration and
development efforts on its inventory of oil and gas properties, further
acquisitions and, to a lesser extent, selected exploratory drilling prospects.
The Company intends to conduct its drilling and workover activities through its
Mustang Service Companies and, if necessary, contracting with independent
drilling contractors and by outsourcing other services. The Company typically
compensates its drilling subcontractors on a turnkey (fixed price), footage or
day rate basis depending on the Company's assessment of risk and cost
considerations.  The Company occasionally utilizes contract services in its oil
field operations and will employ independent consultants from time to time to
evaluate Company prospects, reserves and other oil and gas assets.

         DEVELOPMENT DRILLING AND WORKOVER.  The Company's development strategy
focuses on maximizing the value and productivity of its oil and gas asset base
through development drilling, workovers and enhanced recovery projects.  The
Company has budgeted approximately $6 million for exploitation and development
activities for 1998.  The Company has identified over 100 development drilling
and workover locations (including both production and injection wells) on its
properties.  In exploiting its producing properties, the Company relies upon
its in-house technical staff and utilizes the services of outside consultants
on a selective basis.

         WATERFLOODS.  The Company believes it can enhance the value of its
Means Unit through in-fill drilling and water injection.  While waterfloods
typically take considerable time to respond to fluid injection, the Mean Unit
has some potential, based on staged installation of water flood facilities that
would result in a somewhat faster increase in production and cash flow.  The
Company has budgeted approximately $3 million in 1998 for the Means Unit
waterflood project.

         EXPLORATORY DRILLING.  Although the Company is not currently engaged
in any significant exploration drilling, it intends to increase its activities
in this area in the future and may spend up to $500,000 during the next 12
months for exploratory drilling.  The Company will attempt to lessen the risks
inherent in exploratory drilling by (i) concentrating in specific areas in the
United States where the Company's technical staff has considerable experience
and which are in known producing trends where the potential for significant
reserves exists; (ii) diversifying through investment in multiple prospects;
(iii) utilizing 3-D seismic and other advanced technologies, including
directional and horizontal drilling, and (iv) promoting out interests to
industry partners.

MARKETING OF PRODUCTION

         The Company markets all of its gas production as well as gas it
purchases from third parties to gas marketing firms or end users either on the
spot market on a month-to-month basis at prevailing spot market prices or at
negotiated prices under long-term contracts.  Marketing gas for its own account
exposes the Company to the attendant commodities risk.  During 1997, 54% of the
Company's gas sales were to HS Energy Services, an Oklahoma gas marketing firm.
Another 28% and 11% of sales were to two gas pipeline companies, Transok, Inc.
and Wasatch Energy, respectively.  During 1998, the Company anticipates that
the majority of its gas sales will go to HS Energy Services and Transok, Inc.
The Company does not believe that the loss of any one of its gas purchasers
will have any material adverse effect on the Company or its business.

         The Company normally sells its own oil under month-to-month contracts
with a variety of purchasers.  During 1997, the Company made 57% of its oil
sales to National Cooperative Refinery Association.  Another 15% of its oil
sales were to Phillips 66 Company.  During 1998, the Company anticipates the
majority of its oil sales





                                       -30-
<PAGE>   32
will be to these two purchasers.  While the Company has historically been able
to sell oil above posted prices, it is also exposed to the commodities risk
inherent in short-term contracts.  The Company does not believe that the loss
of any one of its oil purchasers will have any material adverse effect on the
Company or its business.

         The market for oil and gas produced by the Company depends on factors
beyond its control, including the extent of domestic production and imports of
oil and gas, the proximity and capacity of gas pipelines and other
transportation facilities, weather, demand for oil and gas, the marketing of
competitive fuels and the effects of state and federal regulation.  The oil and
gas industry also competes with other industries in supplying the energy and
fuel requirements of industrial, commercial and individual consumers.

OIL AND GAS RESERVES

         GENERAL.  All information set forth in this Prospectus regarding
estimated proved reserves, related estimated future net cash flows and SEC
PV-10 of the Company's oil and gas interests is taken from reports prepared (i)
by K&A Energy Consultants, Inc. with respect to the Company's interests in the
Cheneyboro Field and N.E. Alden Field and (ii) by Ryder Scott Company with
respect to the Means Unit at June 30, 1997.  The estimates of these independent
petroleum engineers were based upon their review of production histories and
other geological, economic, ownership and engineering data provided by the
Company.  There are minor additional interests related to the Old Aspen
acquisition located in Louisiana, Oklahoma and Texas which have not been
included in the following tables.  The following tables also do not include
1,500 net acres of additional leasehold interests in the Cheneyboro Field nor
do such tables reflect any reserve information for the Zama Lake Property,
Sears Ranch Prospect or East Binger Unit.

         In accordance with Commission guidelines, the estimates of future net
cash flows from Proved Reserves and their SEC PV-10 are made using oil and gas
sales prices in effect as of the dates of such estimates and are held constant
throughout the life of the properties.  The Company's estimates of Proved
Reserves, future net cash flows and SEC PV-10 were estimated based on $19.50
per Bbl of oil and $1.95 to $2.25 per Mcf of gas, before deduction of
production taxes.

         All reserves are evaluated at contract temperature and pressure which
can affect the measurement of gas reserves.  Operating costs, development costs
and certain production-related and ad valorem taxes were deducted in arriving
at the estimated future net cash flows.  No provision was made for income
taxes.  The following estimates set forth reserves considered to be
economically recoverable under normal operating methods and existing conditions
at the prices and operating costs prevailing at the dates indicated above.  The
estimates of the SEC PV-10 from future net cash flows differ from the
standardized measure of discounted future net cash flows set forth in the notes
to the Consolidated Financial Statements of the Company, which is calculated
after provision for future income taxes.  There can be no assurance that these
estimates are accurate predictions of future net cash flows from oil and gas
reserves or their present value.

         Proved Reserves are estimates of oil and gas to be recovered in the
future.  Reservoir engineering is a subjective process of estimating the sizes
of underground accumulations of oil and gas that cannot be measured in an exact
way.  The accuracy of any reserve estimates is a function of the quality of
available data and of engineering and geological interpretation and judgment.
Reserve reports of other engineers might differ from the reports contained
herein.  Results of drilling, testing, and production subsequent to the date of
the estimate may justify revision of such estimate.  Future prices received for
the sale of oil and gas may be different from those used in preparing these
reports.  The amounts and timing of future operating and development costs may
also differ from those used.  Accordingly, reserve estimates are often
different from the quantities of oil and gas that are ultimately recovered.
See "Risk Factors -- Uncertainty of Estimates of Reserves and Future Net Cash
Flows."

         Except for the effect of changes in oil and gas prices, no major
discovery or other favorable or adverse event is believed to have caused a
significant change in these estimates of the Company's proved reserves since
June 30, 1997.

         No estimates of Proved Reserves of oil and gas have been filed by the
Company with, or included in any report to, any United States authority or
agency (other than the Commission).

DRILLING ACTIVITY

         The Company did not drill any wells during the two fiscal years ended
June 30, 1997.  During the six-month period ended December 31, 1997, the
Company participated for a 12.5% working interest in a single exploratory well
which was a dry hole.

(1) The number of gross acres is the total number of acres in which a working
    interest is owned.
(2) The number of net acres is the sum of fractional working interests owned in
    gross acres expressed as whole numbers and fractions thereof.

         Substantially all of the Company's interests are leasehold working
interests or overriding royalty interests (as opposed to mineral or fee
interests) under standard onshore oil and gas leases.  As is customary in the
industry, the Company generally acquires oil and gas acreage without any
warranty of title except as to claims made by, through or under the transferor.
Although the Company has title examined by a landman or title attorney prior to
acquisition of developed acreage in those cases in which the economic
significance of the acreage justifies the cost, there can be no assurance that
losses will not result from title defects or from defects in the assignment of
leasehold rights.  In many instances, title opinions may not be obtained if in
the Company's judgment it would be uneconomical or impractical to do so.

COMPETITION

         The oil and gas industry is highly competitive.  Competitors of the
Company include major and other independent oil and gas companies, and
individual producers and operators, many of which have substantially greater
financial resources and larger staffs and facilities than those of the Company.
In addition, the Company frequently encounters competition in the acquisition
of oil and gas properties, and in its well service and equipment business.  The
principal means of competition for acquisitions are the amount and terms of the
consideration offered.  The principal means of such competition with respect to
the sale of oil and gas production are product availability and price.  The
price at which the Company's gas may be sold will continue to be affected by a
number of factors, including the price of alternate fuels such as oil and coal
and competition among various gas producers and marketers.  See "Risk Factors
- -- Competition."

REGULATION

         GENERAL FEDERAL AND STATE REGULATION.  The Company's oil and gas
exploration, production and related operations are subject to extensive rules
and regulations promulgated by federal and state agencies.  Failure to comply
with such rules and regulations can result in substantial penalties.  The
regulatory burden on the oil and gas industry increases the Company's cost of
doing business and affects its profitability.  Because such rules and
regulations are frequently amended or reinterpreted, the Company is unable to
predict the future cost or impact of complying with such laws.

         The State of Texas and many other states require permits for drilling
operations, drilling bonds and reports concerning operations and impose other
requirements relating to the exploration and production of oil and gas.  Such
states also have statutes or regulations addressing conservation matters,
including provisions for the unitization or pooling of oil and gas properties,
the establishment of maximum rates of production from wells, and the regulation
of spacing, plugging and abandonment of such wells.  Many states restrict
production to the market demand for oil and gas.  Some states have enacted
statutes prescribing ceiling prices for gas sold within their states.

         FERC regulates interstate gas transportation rates and service
conditions, which affect the marketing of gas produced by the Company, as well
as the revenues received by the Company for sales of such production.  Since
the mid-1980s, FERC has issued a series of orders, culminating in Order Nos.
636, 636-A and 636-B ("Order





                                      -34-
<PAGE>   36
636"), that have significantly altered the marketing and transportation of gas.
Order 636 mandates a fundamental restructuring of interstate pipeline sales and
transportation service, including the unbundling by interstate pipelines of the
sale, transportation, storage and other components of the city-gate sales
services such pipelines previously performed.  One of FERC's purposes in
issuing the orders is to increase competition within all phases of the gas
industry.  Order 636 and subsequent FERC orders on rehearing have been appealed
and are pending judicial review.  Because these orders may be modified as a
result of the appeals, it is difficult to predict the ultimate impact of the
orders on the Company and its gas marketing efforts.  Generally, Order 636 has
eliminated or substantially reduced the interstate pipelines' traditional role
as wholesalers of gas, and has substantially increased competition and
volatility in gas markets.

         The price the Company receives from the sale of oil and natural gas
liquids is affected by the cost of transporting products to market.  Effective
January 1, 1995, FERC implemented regulations establishing an indexing system
for transportation rates for oil pipelines, which, generally, would index such
rates to inflation, subject to certain conditions and limitations.  The Company
is not able to predict with certainty the effects, if any, of these regulations
on its operations.  However, the regulations may increase transportation costs
or reduce wellhead prices for oil and natural gas liquids.  Finally, from time
to time regulatory agencies have imposed price controls and limitations on
production by restricting the rate of flow of oil and gas wells below natural
production capacity in order to conserve supplies of oil and gas.  See "Risk
Factors -- Laws and Regulations."

         ENVIRONMENTAL REGULATION.  The Company's exploration, development, and
production of oil and gas, including its operation of water injection and
disposal wells, are subject to various federal, state and local environmental
laws and regulations.  Such laws and regulations can increase the costs of
planning, designing, installing and operating oil and gas wells.  The Company's
domestic activities are subject to a variety of environmental laws and
regulations, including but not limited to, the Oil Pollution Act of 1990
("OPA"), the Clean Water Act ("CWA"), the Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA"), the Resource Conservation and
Recovery Act ("RCRA"), the Clean Air Act ("CAA"), and the Safe Drinking Water
Act ("SDWA"), as well as state regulations promulgated under comparable state
statutes.  The Company also is subject to regulations governing the handling,
transportation, storage, and disposal of naturally occurring radioactive
materials that are found in its oil and gas operations.  Civil and criminal
fines and penalties may be imposed for non-compliance with these environmental
laws and regulations.  Additionally, these laws and regulations require the
acquisition of permits or other governmental authorizations before undertaking
certain activities, limit or prohibit other activities because of protected
areas or species, and impose substantial liabilities for cleanup of pollution.

         Under the OPA, a release of oil into water or other areas designated
by the statute could result in the Company being held responsible for the costs
of remediating such a release, certain OPA specified damages, and natural
resource damages.  The extent of that liability could be extensive, as set
forth in the statute, depending on the nature of the release.  A release of oil
in harmful quantities or other materials into water or other specified areas
could also result in the Company being held responsible under the CWA for the
costs of remediation, and civil and criminal fines and penalties.

         CERCLA and comparable state statutes, also known as "Superfund" laws,
can impose joint and several and retroactive liability, without regard to fault
or the legality of the original conduct, on certain classes of persons for the
release of a "hazardous substance" into the environment.  In practice, cleanup
costs are usually allocated among various responsible parties.  Potentially
liable parties include site owners or operators, past owners or operators under
certain conditions, and entities that arrange for the disposal or treatment of,
or transport hazardous substances found at the site.  Although CERCLA, as
amended, currently exempts petroleum, including but not limited to, crude oil,
gas and natural gas liquids from the definition of hazardous substance, the
Company's operations may involve the use or handling of other materials that
may be classified as hazardous substances under CERCLA.  Furthermore, there can
be no assurance that the exemption will be preserved in future amendments of
the act, if any.

         RCRA and comparable state and local requirements impose standards for
the management, including treatment, storage, and disposal of both hazardous
and nonhazardous solid wastes.  The Company generates hazardous and
nonhazardous solid waste in connection with its routine operations.  From time
to time, proposals





                                      -35-
<PAGE>   37
have been made that would reclassify certain oil and gas wastes, including
wastes generated during pipeline, drilling, and production operations, as
"hazardous wastes" under RCRA which would make such solid wastes subject to
much more stringent handling, transportation, storage, disposal, and clean-up
requirements.  This development could have a significant impact on the
Company's operating costs.  While state laws vary on this issue, state
initiatives to further regulate oil and gas wastes could have a similar impact.

         Because oil and gas exploration and production, and possibly other
activities, have been conducted at some of the Company's properties by previous
owners and operators, materials from these operations remain on some of the
properties and in some instances require remediation.  In addition, the Company
has agreed to indemnify sellers of producing properties from whom the Company
has acquired reserves against certain liabilities for environmental claims
associated with such properties.  While the Company does not believe that costs
to be incurred by the Company for compliance and remediating previously or
currently owned or operated properties will be material, there can be no
guarantee that such costs will not result in material expenditures.

         Additionally, in the course of the Company's routine oil and gas
operations, surface spills and leaks, including casing leaks, of oil or other
materials occur, and the Company incurs costs for waste handling and
environmental compliance.  Moreover, the Company is able to control directly
the operations of only those wells for which it acts as the operator.
Notwithstanding the Company's lack of control over wells owned by the Company
but operated by others, the failure of the operator to comply with applicable
environmental regulations may, in certain circumstances, be attributable to the
Company.

         It is not anticipated that the Company will be required in the near
future to expend amounts that are material in relation to its total capital
expenditures program by reason of environmental laws and regulations, but
inasmuch as such laws and regulations are frequently changed, the Company is
unable to predict the ultimate cost of compliance.  There can be no assurance
that more stringent laws and regulations protecting the environment will not be
adopted or that the Company will not otherwise incur material expenses in
connection with environmental laws and regulations in the future.  See "Risk
Factors -- Laws and Regulations."

EMPLOYEES

         At March 4, 1998, the Company had 31 full-time employees of which six
were management, six were administrative and 19 were field employees.  None of
the Company's employees are represented by a union.  The Company has
experienced no work stoppages and management considers its relations with
employees to be good.  The Company uses contract services in its field
operations and employs independent consultants, as needed, to evaluate Company
prospects, reserves and other oil and gas assets for potential acquisitions.

VOTING AGREEMENTS

         Under the terms of a Voting Trust Agreement (the "Voting Agreement"),
unaffiliated parties that transferred their interests in certain properties to
the Company in 1995 in exchange for securities provided a power of attorney to
Eugene A. Soltero and James E. Hogue to vote approximately 3.28 million shares
of Common Stock held by such property contributors until January 1, 2001.  The
Voting Agreement expires with respect to any of the shares of Common Stock
transferred to an unaffiliated third party by such shareholder.  The Company
believes that as of February 28, 1998, approximately 2.5 million shares of
Common Stock were subject to the Voting Agreement.  See "Principal
Stockholders."

         Liviakis Financial Communications, Inc., ("LFC") and its affiliates 
have agreed that, with respect to any shares of Common Stock acquired by them
pursuant to the LFC Consulting Agreement with the Company, they will vote such
shares of Common Stock until January 1, 2001 for directors nominated by Messrs.
Hogue and Soltero and certain other matters. Approximately 2,000,000 shares are
currently subject to this voting rights covenant.  See "Certain Relationships
and Related Transactions" and "Principal Stockholders."

         Pursuant to the terms of the definitive acquisition agreement, the
four previous shareholders of Old Aspen agreed, for a period of five years, to
vote their shares of Common Stock of the Company for directors nominated by
Messrs. Hogue and Soltero.  Messrs. Hogue and Soltero are obligated, upon the
Company's continuance into the Yukon Territory, a jurisdiction which allows a
majority of the directors to be U.S. citizens, to nominate and vote for Mr.
Leon A. Romero, former President of Old Aspen, as a director of the Company.
In February 1998, Mr. Romero was elected as a director, Senior Vice President
and Chief Financial Officer of the Company.  Approximately 2,240,000 shares are
currently subject to this voting covenant.  See "Business and Properties --
Recent Developments; Aspen Acquisition" and "Principal Stockholders."

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         In the Company's Annual Report on Form 10-KSB for the fiscal year
ended June 30, 1997, the Company reported that all persons or entities subject
to the reporting requirements of Section 16(a) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), timely filed all reports required
under the rules and regulations promulgated thereunder.  Subsequent to the
filing of the Annual Report with the Commission, the Company became aware that
both Wayne T. Egan and Richard J. Lachcik, each directors of the Company,
failed to file a Form 3 -- Initial Statement of Beneficial Ownership of
Securities, which filing was due in December 1996, and Form 4's -- Statement of
Changes in Beneficial Ownership of Securities for the months ended September
and October 1997.  On December 19, 1997, Messrs. Egan and Lachcik filed with
the Commission appropriate forms promulgated under Section 16(a) of the
Exchange Act for the purpose of reporting their respective ownership interest
and related transactions in the Company's Common Stock for the noted periods.





                                      -40-
<PAGE>   42
         Except for the events described in the foregoing paragraph, the
Company is not aware of any transactions in its outstanding securities by or on
behalf of any director, executive officer or 10% holder of the Common Stock,
which would require the filing of any report pursuant to Section 16(a) that was
not filed with the Company.

STOCK OPTION PLANS

         1995 PLAN.  Shortly after incorporation in February 1995, the
stockholders of the Company approved the 1995 Stock Option Plan (the "1995
Plan").  The 1995 Plan provided for the reservation of an amount of shares
necessary to cover the issuance of shares upon exercise of all options granted
thereunder, provided such reservation did not exceed 10% of the issued Common
Stock of the Company, or such greater number of shares as determined by the
Board of Directors or approved, if necessary, by the stockholders.  There
presently are outstanding options to purchase 594,000 shares of Common Stock at
a price of $1.83 per share.  The Company does not intend to issue any further
options under the 1995 Plan.

         1997 PLAN.  On February 10, 1998, the stockholders of the Company
approved the 1997 Stock Compensation Plan of Cotton Valley Resources
Corporation (the "1997 Plan") and reserved 1,400,000 shares of Common Stock for
issuance under the plan.  The 1997 Plan terminates on November 13, 2007 unless
previously terminated by the Board of Directors.  The 1997 Plan is administered
by the Compensation Committee or the entire Board of Directors as determined by
the Board of Directors.

         Eligible participants in the 1997 Plan include full time employees,
directors (other than Non-Employee Directors) and advisors of the Company and
its subsidiaries.  Options granted under the 1997 Plan are intended to qualify
as "incentive stock options" pursuant to the provisions of Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), or options which do not
constitute incentive stock options ("nonqualified options") as determined by
the Company's Compensation Committee (the "Committee").

         Under the 1997 Plan the Company may also grant "Restricted Stock"
awards.  "Restricted Stock" represents shares of Common Stock issued to
eligible participants under the 1997 Plan subject to the satisfaction by the
recipient of certain conditions and enumerated in the specific Restricted Stock
grant.  Conditions which may be imposed include, but are not limited to,
specified periods of employment, attainment of personal performance standards
or the overall performance of the Company.  The granting of Restricted Stock
represents an additional incentive for eligible participants under the 1997
Plan to promote the development of the Company, and may be used by the Company
as another means of attracting and retaining qualified individuals to serve as
employees of the Company or its subsidiaries.

         Incentive stock options may be granted only to employees of the
Company or a subsidiary who, in the judgment of the Committee, are responsible
for the management or success of the Company or a subsidiary and who, at the
time of the granting of the incentive stock option, are either an employee of
the Company or a subsidiary.  No incentive stock option may be granted under
the 1997 Plan to any individual who would, immediately before the grant of such
incentive stock option, directly or indirectly, own more than ten percent (10%)
of the total combined voting power of all classes of stock of the Company
unless (i) such incentive stock option is granted at an option price not less
than one hundred ten percent (110%) of the fair market value of the shares on
the date the incentive stock option is granted and (ii) such incentive stock
option expires on a date not later than five years from the date the incentive
stock option is granted.

         The purchase price of the shares of the Common Stock offered under the
1997 Plan must be one hundred percent (100%) of the fair market value of the
Common Stock at the time the option is granted or such higher purchase price as
may be determined by the Committee at the time of grant; provided, however, if
an incentive stock option is granted to an individual who would, immediately
before the grant, directly or indirectly own more than ten percent (10%) of the
total combined voting power of all classes of stock of the Company, the
purchase price of the shares of the Common Stock covered by such incentive
stock option may not be less than one hundred ten percent (110%) of the fair
market value of such shares on the day the incentive stock option is granted.
If the Common Stock is listed upon an established stock exchange or exchanges,
the fair market value of the Common Stock shall be the highest closing price of
the Common Stock on the day the option is granted or, if no sale of the Common
Stock is made on an established stock exchange on such day, on the next
preceding day on which there





                                      -41-
<PAGE>   43
was a sale of such stock.  As the price of the Common Stock is currently quoted
on the American Stock Exchange, the fair market value of the Common Stock
underlying options granted under the 1997 Plan shall be the closing sales price
of the Common Stock on the day the options are granted.  If there is no market
price for the Common Stock, then the Board of Directors and the Committee may,
after taking all relevant facts into consideration, determine the fair market
value of the Common Stock.

         Options are exercisable in whole or in part as provided under the
terms of the grant, but in no event shall an option be exercisable after the
expiration of ten years from the date of grant.  Except in case of disability
or death, no option shall be exercisable after an optionee ceases to be an
employee of the Company, provided that the Committee shall have the right to
extend the right to exercise for a period not longer than three months
following the date of termination of an optionee's employment.  If an
optionee's employment is terminated by reason of disability, the Committee may
extend the exercise period for a period not in excess of one year following the
date of termination of the optionee's employment.  If an optionee dies while in
the employ of the Company and shall not have fully exercised his options, the
options may be exercised in whole or in part at any time within one year after
the optionee's death by the executors or administrators of the optionee's
estate or by any person or persons who acquired the option directly from the
optionee by bequest or inheritance.

         Under the 1997 Plan, an individual may be granted one or more options,
provided that the aggregate fair market value (determined at the time the
option is granted) of the shares covered by incentive options which may be
exercisable for the first time during any calendar year shall not exceed
$100,000.  There presently are outstanding options to purchase 600,000 shares
of Common Stock at a price of $1.65 per share.  Under the 1997 Plan, the
Company granted in February 1998 to each of Eugene A. Soltero and James E.
Hogue, 300,000 options, each exercisable at a price of $1.65 per share until
February 23, 2003.

         NON-EMPLOYEE DIRECTORS STOCK OPTION PLAN.  The stockholders of the
Company in February 1998 approved the Non- Employee Directors Stock Option Plan
of Cotton Valley Resources Corporation (the "Directors Plan") and reserved for
issuance 200,000 shares of Common Stock for issuance under the plan.  The
Directors Plan terminates on November 13, 2007 unless previously terminated by
the Board of Directors.  The Directors Plan is administered by the Stock Option
Committee or by the entire Board of Directors as determined by the Board of
Directors.

         Eligible participants in the Directors Plan are non-employee directors
of the Company and its subsidiaries.  Options which do not constitute incentive
stock options (non-qualified options) may only be granted under the Directors
Plan.  The Directors Plan shall be administered by the Company's Stock Option
Committee (the "Stock Option Committee").

         Each non-employee director shall be granted, without further action on
the part of the Board of Directors or such individual an option to purchase
1,000 shares of Common Stock on the day of the non-employee director's
appointment or election to the Board of Directors, which ever comes first.
Thereafter, on each anniversary of the non-employee director's election or
appointment to the Board, such individual, without further action of the Board
of Directors or the individual shall receive an option to purchase 1,000 shares
of Common Stock, assuming said individual continues to be a non-employee
director.  Discretionary option grants may also be made to eligible
participants by the Stock Option Committee or the Board of Directors.

         The purchase price of the shares of the Common Stock offered under the
Directors Plan must be one hundred percent (100%) of the fair market value of
the Common Stock at the time the option is granted or such higher purchase
price as may be determined by the Stock Option Committee at the time of grant.
If the Common Stock is listed upon an established stock exchange or exchanges,
the fair market value of the Common Stock shall be the highest closing price of
the Common Stock on the day the option is granted or, if no sale of the Common
Stock is made on an established stock exchange on such day, on the next
preceding day on which there was a sale of such stock.  As the price of the
Common Stock is currently quoted on the American Stock Exchange, the fair
market value of the Common Stock underlying options granted under the Directors
Plan shall be the closing sales price of the Common Stock on the day the
options are granted.  If there is no market price for the Common Stock, then
the Board of Directors and the Stock Option Committee may, after taking all
relevant facts into consideration,





                                      -42-
<PAGE>   44
determine the fair market value of the Common Stock.  There presently are no
outstanding options granted under the Directors Plan.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         In February 1995, the Company issued a total of 560,001 shares of
Common Stock to Eugene A. Soltero, Chairman of the Board and Chief Executive
Officer, and James E. Hogue, President and Chief Operating Officer, for pre-
incorporation services valued at $1,401.  Shortly after incorporation, the
Company issued 2,100,000 special shares to Messrs. Soltero and Hogue which were
subsequently exchanged for 1,440,000 shares of Common Stock of the Company
valued at $5,832. See "Management" and "Principal Stockholders."

         In December 1995, the Company issued 80,000 shares of Common Stock to
each of Messrs. Soltero and Hogue for pre-incorporation services valued at
$0.04 per share.  Additionally, since June 14, 1996, the Company has granted to
each of Messrs. Soltero and Hogue options to purchase 83,333 shares of Common
Stock at $0.73 per share and options to purchase 500,000 shares at prices
ranging from $1.65 to $1.83 per share.

         During the fiscal years ended June 30, 1996 and 1995, the Company paid
management fees to two family corporations controlled by Messrs. Soltero and
Hogue aggregating $160,000 and $50,000, respectively, in lieu of salaries.  In
addition, the Company has received advances from these two companies which
totaled $139,710 at June 30, 1997.  As of December 31, 1997, $119,710 of the
advances remained outstanding.  The advances are unsecured and without interest
and are payable after January 1, 1999.

         During the year ended June 30, 1997, the Company paid to Weir & Foulds
approximately $50,000 in legal fees.  Most of the legal services were provided
by Richard Lachcik and Wayne Egan, directors of the Company, who are members of
Weir & Foulds. Messrs. Lachcik and Egan each received in fiscal year 1997
options to purchase 50,000 shares of Common Stock at $1.83 per share.

         In November 1996, the Company entered into a consulting agreement (the
"LFC Consulting Agreement") with Liviakis Financial Communications, Inc., a
California corporation ("LFC").  Under the terms of the LFC Consulting
Agreement, LFC was retained to assist and consult with the Company in matters
concerning corporate finance and to represent the Company in investors'
communications and public relations with existing stockholders, brokers and
other investment professionals.  As consideration for LFC undertaking the
engagement, the Company issued and delivered to LFC an aggregate of 1,490,000
shares of Company's Common Stock as non-forfeitable compensation.  The stock
issuance was recorded at $1,087,800 based on the Company's stock price at the
date of the LFC Consulting Agreement.

         In connection with LFC undertaking the consulting engagement, the
Company sold to LFC and Robert B. Prag, an affiliate of LFC, 500,000 units (the
"Units") for $375,000 or $0.75 per Unit.  Each Unit consisted of one share of
the Company's Common Stock and one stock purchase warrant (a "LFC Warrant")
which entitled the holder thereof to purchase a share of the Company's Common
Stock at an exercise price of $0.80 through November 7, 2001.  The estimated
value of the stock purchase warrants of $199,000 was recorded as an expense. See
"Description of Securities -- Warrants; LFC Warrants" and "Selling
Stockholders."

         The LFC Consulting Agreement provided that any shares of Common Stock
received by LFC and its affiliate under the LFC Consulting Agreement, either
directly or indirectly through the exercise of warrants, shall be voted in
connection with the election of directors for such nominees as may be
designated by Eugene A. Soltero, Chairman of the Board and Chief Executive
Officer of the Company, and James E. Hogue, President and Chief Operating
Officer of the Company, and with respect to related matters in such manner as
Messrs. Soltero and Hogue may designate.  The voting rights covenant is
applicable for any vote of stockholders for the election of directors or any
related matter (such as increasing or decreasing the number of directors or
creating a classified board of directors) until January 1, 2001.  Any shares of
Common Stock transferred by LFC and its affiliate to persons or entities not
subject to the control of LFC shall be transferred free of this voting rights
covenant.  At February 28, 1998, approximately 2,000,000 outstanding shares of
the Company's Common Stock owned by LFC and its affiliates were subject to the
voting rights covenant.  The LFC Consulting Agreement expired on January 2,
1998.  See "Management -- Voting Agreements," "Principal Stockholders" and
"Selling Stockholders."





                                      -43-
<PAGE>   45
         As further compensation to LFC, the Company agreed to compensate LFC
with a fee in the event that LFC introduces the Company, or its nominees, to a
lender or equity purchaser, not already having a pre-existing relationship with
the Company and such financing is ultimately consummated.  In connection with
the sale by the Company of its Convertible Debentures in December 1997, LFC
received a cash fee of $108,000.  See "Business and Properties -- Recent
Developments; Sale of Convertible Debentures" and "Description of Securities --
Convertible Debentures."

         On June 24, 1997, the Company issued to LFC a 9% Convertible Secured
Promissory Note (the "LFC Note") for a $579,000 loan.  On December 3, 1997, the
Company repaid $479,000 of the principal amount of the LFC Note and accrued
interest.  LFC converted the remaining principal amount of $100,000 into 60,000
shares of the Company's Common Stock ($1.67 per share).  As additional
consideration for the loan, the Company issued to LFC warrants (the "Liviakis
Warrants") expiring April 3, 2002 to purchase 161,351 shares of the Company's
Common Stock at an exercise price of $2.08 per share.  See "Description of
Securities -- Warrants; Liviakis Warrants."

         Additionally, in December 1997, the Company agreed to issue to LFC
warrants to purchase 100,000 shares of the Company's Common Stock exercisable at
$3.50 per share until December 31, 2000 (the "LFC Mustang Warrants"), as
additional compensation for LFC's assistance to the Company in completing
acquisitions and other financings during calendar 1997. LFC directed the Company
to issue 25,000 of the Mustang Warrants to Robert B. Prag, an officer of LFC. 
See "Description of Securities -- Warrants; Mustang Warrants."

         The LFC Consulting Agreement further provides that the Company shall
file with the Commission a registration statement under the Securities Act
covering, among other securities, the shares of Common Stock issued to LFC and
its affiliates including shares of stock underlying the LFC Warrants, Liviakis
Warrants and LFC Mustang Warrants.  Of the 10,891,184 Shares offered hereby,
2,811,351 shares are being offered by LFC and Robert B. Prag.  See "Selling
Stockholders" and "Description of Securities -- Warrants."

         Leon A. Romero, Senior Vice President, Chief Financial Officer and a
director of the Company received 977,771 net shares of Common Stock from the
Company in July 1997 as a result of the Aspen Acquisition.  Mr. Romero was one
of the selling stockholders of Old Aspen.  See "Business and Properties --
Recent Developments; Aspen Acquisition," "Management," "Selling Stockholders"
and "Agreements with Selling Stockholders."

         The transactions described in this section were ratified by a majority
of the Company's independent directors who did not have an interest in the
transactions and who had access, at the Company's expense, to the Company's or
independent counsel.

         Any future transactions between the Company and its affiliates will be
approved by a majority of disinterested directors and will be on terms no less
favorable to the Company than those which could be obtained from unrelated
third parties.  Any forgiveness of loans must be approved by a majority of the
Company's independent directors who do not have an interest in the transactions
and who have access, at the Company's expense, to the Company's or independent
legal counsel.

                           DESCRIPTION OF SECURITIES

COMMON STOCK

         The Company is presently authorized to issue an unlimited number of
shares of Common Stock, no par value, of which 17,073,248 shares were issued
and outstanding at March 9, 1998.  The holders of Common Stock are entitled to
equal dividends and distributions, per share, with respect to the Common Stock
when, as and if declared by the Board of Directors from funds legally available
therefor.  No holder of any shares of Common Stock has a preemptive right to
subscribe for any securities of the Company nor are any shares of Common Stock
subject to redemption or convertible into other securities of the Company.
Upon liquidation, dissolution or winding up of the Company, and after payment
of creditors and preferred shareholders, if any, the assets will be divided pro
rata on a share-for-share basis among the holders of the shares of Common
Stock.  All shares of Common Stock now outstanding are fully paid, validly
issued and non-assessable.  Holders of the Common Stock do not have cumulative
voting rights, so that holders of more than 50% of the combined shares voting
for the election of directors may elect all of the directors, if they choose to
do so and, in that event, the holders of the remaining shares will not be able
to elect any members to the Board of Directors.  At March 9, 1998, there are
reserved for issuance (i) 2,580,440 shares of Common Stock issuable upon
exercise of various outstanding warrants; (ii) 1,360,666 shares of Common Stock
issuable upon exercise of options held by management and other employees; (iii)
up to 4.8 million shares of Common Stock reserved for issuance upon conversion
of the Convertible Debentures; (iv) up to 1.2 million shares reserved for
issuance upon exercise of the Debenture Warrants; and (v) 1,000,000 shares
reserved for issuance upon grant of future options under the Company's 1997
Plan and Director's Plan.  See "Business and Properties -- Recent Developments;
Sale of Convertible Debentures," "Management -- Options," and "-- Stock Option
Plans." Also see "-- Warrants" and "-- Convertible Debentures" below.

PREFERRED STOCK

         Under the Company's Articles of Amalgamation, as amended, the Board of
Directors has the power, generally without further action by the holders of the
Common Stock, to designate the relative rights and preferences of the preferred
stock, no par value (the "Preferred Stock"), and issue the Preferred Stock in
one or more series as designated by the Board of Directors. The Board of
Directors has authorized the issuance of up to 2,000,000 shares of 8%
Cumulative Convertible Preferred Stock (the "Convertible Preferred Stock.")
The designation of rights and preferences could include preferences as to
liquidation, redemption and conversion rights, voting rights, dividends or
other preferences, any of which may be dilutive of the interest of the holders
of the Common Stock or other series of Preferred Stock.  The issuance of
Preferred Stock may have the effect of delaying or preventing a change in
control of the Company without further shareholder action and may adversely
affect the rights and powers, including voting rights, of the holders of Common
Stock.  In certain circumstances, the issuance of Preferred Stock could depress
the market price of the Common Stock.  There are no outstanding shares of
Preferred Stock and the Company does not have any present intention of issuing
any shares of Preferred Stock, including the Convertible Preferred Stock.

         If the Convertible Preferred Stock was issued, holders thereof would
be entitled to two votes per share on all matters submitted to a vote of the
Company's shareholders.  In addition, such holders would be entitled to receive
cumulative dividends at the rate of 8% per annum, payable at the election of
the Company in cash or in shares of Common Stock.  Holders of Convertible
Preferred Stock would have a liquidation preference, limited to $6.00 per share
of Convertible Preferred Stock; and each outstanding share of Convertible
Preferred Stock would be convertible at any time by the holder into two shares
of Common Stock.

LLC and two individuals.  Each Newport Warrant enables the holder thereof to

None of the Newport Warrants have been exercised.

CONVERTIBLE DEBENTURES

         On December 30, 1997, the Company completed the private placement of
$4,320,000 of its 7% Secured Convertible Debentures ("Convertible Debentures")
to a group of eight institutional investment firms led by a Fort Worth, Texas
institutional energy investor.  Approximately $1 million of the cash proceeds
and $220,000 of Convertible Debentures were used to purchase the Equipment.
The remaining funds will be used for the acquisition and development of oil and
gas properties and purchase of oil field equipment.

         The Convertible Debentures are due December 31, 2001 and are secured
by the Equipment and other assets of the Company, including the unutilized
proceeds from the sale of the Convertible Debentures (the "Restricted Cash").
At December 31, 1997, the Company had approximately $2.5 million of Restricted
Cash.  The Convertible Debentures are convertible into a minimum of 1.6 million
shares of the Company's Common Stock and a minimum of 400,000 warrants
("Debenture Warrants"), subject to adjustment upon certain events, exercisable
at prices related to the conversion price at the time of conversion, with
limits on rights to convert if the conversion price of the Company's Common
Stock falls below a floor price of $1.80 per share (the "Floor Price").  The
conversion price is the lesser of $2.70 per share or 90% of the average of the
three lowest closing bid prices during the ten trading days prior to the notice
of conversion.  During any thirty-day period, any investor may not tender for
conversion more than 10% of his originally purchased Convertible Debentures at
a conversion price less than the Floor Price.  The Company may elect to redeem
(for a 10% premium) any Convertible Debentures tendered for conversion at any
price below the Floor Price.

         In addition to the usual and customary covenants contained in
convertible debenture agreements of this nature, the Company is required to
reserve shares of Common Stock in an amount not less than 200% of the number of
shares of Common Stock that would be issuable upon conversion in full of the
Convertible Debentures and full exercise of the Debenture Warrants granted
thereunder.  In furtherance of this covenant, the Company is required to seek
stockholder approval of an increase in the Company's authorized shares if
necessary to maintain such reserves.  Furthermore, any holder of Convertible
Debentures shall not be permitted to convert its Convertible Debentures or
exercise its Debenture Warrants to the extent that such conversion or exercise
would result in a beneficial ownership in the Company in excess of 4.999%.  The
Convertible Debenture holders have a right of first refusal for future
financing of the Company under certain conditions.  The Company has listed an
additional 3.2





                                      -48-
<PAGE>   50
million shares of its Common Stock on AMEX for the shares underlying the
Convertible Debentures and shares to be issued upon exercise of the Debenture
Warrants.  Although the Company's Registration Statement, of which this
Prospectus is a part, includes 3.2 million shares, which the Company currently
believes will provide sufficient shares upon the conversion of the Convertible
Debentures and upon exercise of all the Debenture Warrants, the Company has
reserved for issuance up to 4.8 million shares of its Common Stock to be
issued, if necessary, upon conversion of the Convertible Debentures and up to
1.2 million shares to be issued, if necessary, upon exercise of the Debenture
Warrants.  See "Business and Properties -- Recent Developments; Sale of
Convertible Debentures," "Selling Stockholders" and "Agreements with Selling
Stockholders."

TRANSFER AGENT AND REGISTRAR

         The co-transfer agents and co-registrars for the Company's Common
Stock are Equity Transfer Services Inc. of Toronto, Ontario, Canada and
Continental Stock Transfer & Trust Co. of New York.

                        SHARES ELIGIBLE FOR FUTURE SALE

         Sales of Shares offered hereby could have an adverse effect on the
market price of the Common Stock.  As of the date of this Prospectus, there are
approximately 17,073,248 shares of Common Stock outstanding, which amount does
not include 3,941,106 shares which underlie outstanding options and warrants,
including 2,548,309 shares reserved for issuance upon exercise of outstanding
warrants held by certain Selling Stockholders, or up to 3.2 million shares
offered hereby by the Convertible Debenture holders, assuming conversion of the
Convertible Debentures and exercise of Debenture Warrants.  Substantially all of
the Company's outstanding shares of Common Stock and the Shares offered hereby
are eligible for public sale without restriction, except for shares purchased by
affiliates of the Company (those controlling or controlled by or under common
control with the Company and generally deemed to include officers and
directors).  Approximately 665,485 shares of the Company's outstanding Common
Stock are deemed "restricted securities," as that term is defined under Rule 144
promulgated under the Securities Act.  See "Management" and "Description of
Securities."

         A person, including an affiliate of the Company (or persons whose
shares are aggregated into such affiliate), who has owned restricted shares of
Common Stock beneficially for at least one year is entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of one
percent of the total number of outstanding shares of the same class or the
average weekly trading volume of the Common Stock during the four calendar
weeks preceding the sale.   Subject to the volume and holding period
limitations of Rule 144, 596,638 outstanding shares of Common Stock are
eligible for sale under Rule 144.  A person who has not been an affiliate of
the Company for at least the three months immediately preceding the sale and
who has beneficially owned shares of Common Stock for at least two years is
entitled to sell such shares under Rule 144(k) without regard to any of the
limitations described above.

         The possibility that substantial amounts of Common Stock may be sold
in the public market may adversely affect the prevailing market price for the
Common Stock and could impair the Company's ability to raise capital through
the sale of its equity securities.

"Description of Securities -- Warrants," "Certain Relationships and Related

                              PLAN OF DISTRIBUTION


     The Shares offered hereby may be sold by the Selling Stockholders, or by
pledgees, donees, transferees or other successors in interest thereof. 

     Offers and sales of the Shares may be made from time to time on one or
more exchanges or in the over-the-counter market, or otherwise, at prices and
on terms then prevailing or at prices related to the then-current market price,
or in negotiated transactions. The methods by which the Shares may be sold may
include, but not be limited to, the following: (a) a block trade in which the
broker or dealer so engaged will attempt to sell the Shares as agent but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a broker or dealer as principal and resale by
such broker or dealer for its account in accordance with any method of sale
described herein; (c) an exchange distribution in accordance with the rules of
such exchange; (d) ordinary brokerage transactions in which the broker solicits
purchasers; (e) privately negotiated transactions; (f) short sales; and (g) a
combination of any such methods of sale. In effecting sales, brokers and dealers
engaged by the Selling Stockholders may arrange for other brokers or dealers
to participate. Brokers or dealers may receive commissions or discounts from
the Selling Stockholders or from the purchasers in amounts to be negotiated
prior to the sale. The Selling Stockholders may also sell such Shares in
accordance with Rule 144 under the Securities Act of 1933, as amended (the
"Securities Act"), if available.

     From time to time the Selling Stockholders may engage in short sales,
short sales against the box, puts and calls and other transactions in
securities of the Company or derivatives thereof, and may sell and deliver the
Shares in connection therewith. From time to time Selling Stockholders may
pledge their Shares pursuant to the margin provisions of their respective
customer agreements with their respective brokers. Upon a default by a Selling
Stockholder, the broker may offer and sell the pledged Shares of Common Stock
from time to time.

     The Company has agreed to use its best efforts to maintain the
effectiveness of the registration of the Shares being offered hereunder for
three years from the date of this Prospectus or such earlier date when all of
the Shares being offered hereunder have been sold or may be sold without volume
or other restrictions pursuant to Rule 144 under the Securities Act, as
determined by counsel to the Company pursuant to a written opinion letter.

     The Selling Stockholders and any brokers participating in such sales may be
deemed to be underwriters within the meaning of the Securities Act. There can
be no assurance that the Selling Stockholders will sell any or all of the
Shares offered hereunder.

     All proceeds from any such sales will be the property of the Selling
Stockholder who will bear the expense of underwriting discounts and selling
commissions. The Company is required to pay all other fees and expenses
incident to the offering and sale of the Shares. The Company has agreed to
indemnify the Selling Stockholders against certain losses, claims, damages and
liabilities, including liabilities under the Securities Act.

                      AGREEMENTS WITH SELLING STOCKHOLDERS

ASPEN ACQUISITION

      On June 30, 1997, the Company acquired all the issued and outstanding
shares of Old Aspen (the "Old Aspen Shares") from Leon A. Romero, George W.
Peel, Albert Sena and Dorothy Carter (the "Aspen Shareholders").  The purchase
price for the Old Aspen Shares consisted of $200,000 cash, $300,000 of
short-term notes, 2,511,317 shares of Common Stock (the "Aspen Shares"), of
which 270,000 shares were returned to the Company by three Old Aspen
Shareholders in settlement of notes payable to Old Aspen in the amount of
$425,000.  The acquisition also included various interests, having an aggregate
value of less than $500,000, in two wells in Utah, which were subsequently sold
by the Company, two wells in Latimer County, Oklahoma, one well in Harrison
County, Texas and several shallow wells in Gregg County, Texas.

      Under the terms of the Aspen Agreement, the Aspen Shareholders agreed not
to sell or otherwise transfer the Aspen Shares except in compliance with the
Aspen Agreement.  This restriction terminates (i) as to 60,000 Aspen Shares
each month beginning on September 1, 1997 and continuing the first day of each
month thereafter through July 1, 1998, and (ii) as to any remaining shares on
August 1, 1998.  As of March 9, 1998, 1,821,317 Aspen Shares remain subject to
this restriction.

WPM FINANCING

      In September 1997, the Company completed a private offering of 15%
Two-Year Promissory Notes (the "WPM Notes") in the aggregate amount of $125,000
and issued 272,700 shares of its Common Stock and 322,700 WPM Warrants for
$454,500 (the "WPM Financing") to Bill J. Kemp, Dan Malone, Fred B. Dulock, Jack
Mabery, Darlene Mabery, Jim Phillips, John Malone, P.C., and R.J. Blanyer. WPM
Group, an affiliate of John Malone, acted as placement agent and received a cash
fee and 32,500 WPM Warrants for its services.  See "Description of Securities --
Warrants; WPM Warrants.".

      The WPM Notes provide for interest at the rate of 15% per annum with
interest payments due quarterly beginning October 18, 1998 and continuing until
the WPM Notes mature on July 17, 1999, when the entire balance of principal and
accrued interest is due.  The WPM Notes are secured by a deed of trust creating
a first lien on certain oil and gas leases situated in Navarro County, Texas.
At February 28, 1998, $125,000 of the WPM Notes were outstanding.

MALONE CONSULTING AGREEMENT

      On April 3, 1997, the Company entered into a consulting agreement (the
"Malone Consulting Agreement") with John Malone, P.C. ("Malone").  The Malone
Consulting Agreement expires on April 3, 1998.  Malone was retained by the
Company to assist the Company with its capital raising efforts during fiscal
1997.  As consideration for Malone undertaking this engagement, the Company
agreed to issue to Malone warrants to purchase 80,000 shares of the Company's
Common Stock for $1.84 per share which expire April 3, 2002 as well as such
additional warrants as determined in the sole discretion of the Company based
upon the performance of Malone under the Malone Consulting Agreement.  A total
of 116,900 Malone Warrants have been issued to Malone pursuant to this
Agreement.  See "Description of Securities -- Warrants; Malone Warrants."

HIBERNIA SECURITIES TRUST AGREEMENT

      Effective January 30, 1997, the Company entered into a subscription
agreement (the "Hibernia Agreement") with Hibernia Securities Trust
("Hibernia").  Pursuant to the terms of the Hibernia Agreement, Hibernia
subscribed for an aggregate of 266,667 Units, at a price of $1.64 per Unit as
determined in accordance with the terms of the Hibernia Agreement.  Pursuant to
the terms of the Hibernia Agreement, 266,667 shares of Common Stock and





                                      -53-
<PAGE>   55
266,667 HST Warrants were issued to Hibernia for aggregate proceeds of
$438,000.  See "Description of Securities -- Warrants; HST Warrants."

HIBERNIA MANAGEMENT COMPANY AGREEMENT

      In a private placement completed in January 1996, the Company issued to
HMC 200,000 shares of Common Stock and 300,000 HMC Warrants for total
consideration of $164,250.  During March 1997, affiliates of Mr. Soltero and
Mr. Hogue purchased the 200,000 shares from HMC for $164,250.  See "Description
of Securities -- Warrants; HMC Warrants."

CHENEYBORO NOTE CONVERSION

      During June 1997, the Company repaid $549,000 of outstanding notes
secured by oil and gas leases in the Cheneyboro Field by delivery to the
noteholder of $200,000 cash, 302,191 shares of Common Stock and 302,191
Cheneyboro Warrants.  The securities have been transferred to Euro Coach
America Corporation, NPCS, Inc. and Hibernia Management Company.  See
"Description of Securities -- Warrants; Cheneyboro Warrants."

                       CERTAIN INCOME TAX CONSIDERATIONS

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS FOR UNITED STATES RESIDENTS

         The following is a summary of certain of the Canadian federal income
tax considerations which will generally be applicable to holders of common
stock ("U.S. residents") who are residents of the United States for the
purposes of the Canada-United States Income Tax Convention (1980) ("the
Convention") and are not residents of Canada for the purposes of the Income Tax
Act (Canada) ("the Canadian Tax Act"), who deal at arm's length with the
Company for the purposes of the Canadian Tax Act and who do not use or hold and
are not deemed to use or hold such common stock in, or in the course of,
carrying on a business in Canada.  This summary is based upon the current
provisions of the Canadian Tax Act and the regulations thereunder, proposed
amendments thereto publicly announced by the Minister of Finance, Canada, prior
to the date hereof, and the provisions of the Convention as in effect on the
date hereof.

         THIS SUMMARY IS OF GENERAL NATURE ONLY AND IS NOT INTENDED TO BE LEGAL
OR TAX ADVICE TO ANY PARTICULAR U.S.  RESIDENT.  ACCORDINGLY, U.S. RESIDENTS
SHOULD CONSULT WITH THEIR OWN TAX ADVISORS FOR ADVICE WITH RESPECT TO THEIR OWN
PARTICULAR CIRCUMSTANCES.

         A U.S. resident will not be subject to tax in Canada on any capital
gain realized on a disposition of the Securities unless the value of the
Securities constitutes "taxable Canadian property" of the U.S. resident and the
value of the Securities is derived principally from real property situated in
Canada.  The value of these Securities is not derived principally from real
property situated in Canada.

         Dividends paid or credited or deemed to be paid or credited to a U.S.
resident in respect of the common stock will generally be subject to Canadian
withholding tax.  The Income Tax Act (Canada) requires 25% tax withholding from
any dividends paid or deemed to be paid to non-Canadian stockholders.  However,
under the Convention, the rate of Canadian withholding tax which would apply on
dividends paid by the Company to a resident of the United States is (i) 6% with
respect to dividends paid in 1996 and 5% thereafter if the beneficial owner of
the dividends is a company which owns at least 10% of the voting stock of the
Company, and (ii) 15% in all other cases.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

         The following is a general description of the material United States
federal income tax consequences applicable to U.S. holders of the Shares.  The
following discussion deals only with Shares held as a capital asset by U.S.
holders.  It does not deal with special situations, such as those of foreign
persons, dealers in securities, financial institutions, life insurance
companies, holders whose "functional currency" is not the United States dollar,
or certain "straddle" or hedging transactions.  A "U.S. holder" is (i) a
citizen (not resident in Canada pursuant to the convention) or resident of the
United States, (ii) a corporation created or organized under the laws of the
United States or any state thereof (including the District of Columbia) or
(iii) a person otherwise subject to United States federal income tax on its
worldwide income.  PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR TAX
ADVISORS REGARDING THE PARTICULAR TAX CONSEQUENCES ARISING UNDER ANY STATE OR
LOCAL LAW.

         The gross amount of a distribution with respect to Common Stock will
include the amount of any Canadian federal income tax withheld and will be
includable in gross income as a taxable dividend to the extent of the Company's
current and accumulated earnings and profits (calculated under United States
tax principles), as a return of capital to the extent in excess of such
earnings and profits and not in excess of the holder's tax basis in the Common
Stock, and as capital gain to the extent of any balance.  Dividends will not be
eligible for the dividends-received deduction. Holders generally will be
entitled, subject to certain limitations, to a credit against





                                      -55-
<PAGE>   57
their United States federal income tax for Canadian federal income taxes
withheld from such dividends.  Holders may claim a deduction for such taxes if
they do not elect to claim such foreign tax credit.

         If a dividend distribution is paid in Canadian dollars, the amount
includable in income will be the United States dollar value, on the date of
receipt, of the Canadian dollar amount distributed.  Any subsequent gain or
loss in respect of such Canadian dollars arising from exchange rate
fluctuations will be ordinary income or loss.

         The sale of Common Stock will generally result in the recognition of
gain or loss in an amount equal to the difference between the amount realized
on the sale and the holder's adjusted basis in such common stock.  Gain or loss
upon the sale of the Common Stock will be long-term or short-term capital gain
or loss, depending on whether the Common Stock has been held for more than one
year.

         Special rules are applicable to United States persons holding stock in
a "passive foreign investment company" (PFIC), any foreign corporation of which
at least 75% of its gross income for the taxable year is passive income (the
"Income Test") or at least 50% by value of the assets it holds during the
taxable year produce or are held for the production of passive income (the
"Asset Test").  For that purpose, "passive income" includes the excess of gains
over losses from certain commodities transactions, including certain
transactions involving oil and gas.  Gains from commodities transactions,
however, are generally excluded from the definition of passive income if
"substantially all" of a merchant's, producer's or handler's business is as an
active merchant, producer or handler of such commodities.

         The Company believes it is not currently and will not become a PFIC.
However, the application of the PFIC provisions of the Internal Revenue Code of
1986, as amended (the "Code"), to oil and gas producers is somewhat unclear.
Therefore, no assurance can be made regarding the PFIC status of the Company.

         If the Company was a PFIC, a U.S. holder of Common Stock would be
subject to a special tax regime with respect to certain dividends and with
respect to gain on a disposition of such shares (including a gift or pledge of
shares).  Such income would be allocated ratably over the holder's holding
period for the shares, would be taxed, in the year of dividend or disposition,
at ordinary income tax rates (using the highest tax rate in effect for each
period to which the income is allocated), and would be subject to an interest
charge reflecting the deferral of tax from the year to which the income was
allocated to the year of dividend or disposition.

         PURCHASERS OF SHARES ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING
THE POTENTIAL APPLICATION OF THE MATTERS DESCRIBED ABOVE.

                       LIMITATIONS ON DIRECTOR LIABILITY

         Under the securities law of the Yukon Territory, a right of action is
given for damages for a "misrepresentation" contained in a prospectus at the
time of purchase against every director of the issuer at the time the
prospectus or its later amendment was filed.  A misrepresentation is defined to
mean an untrue statement of material fact or an omission to state a material
fact that is required to be stated or that is necessary to make a statement not
misleading in the light of the circumstances in which it was made.  Every
person who purchases the security offered by the prospectus during the period
of distribution is deemed to have relied upon the misrepresentation if it was a
misrepresentation at the time of purchase.

         The general defense available for directors to such an action is proof
by the director that the purchaser purchased the securities with knowledge of
the misrepresentation.  In addition, specific defenses are available to
directors provided a director can demonstrate that the prospectus was filed
without the director's knowledge and consent and reasonable general notice was
given on becoming aware of the filing.  In addition, a director may also avoid
liability for a misrepresentation in a prospectus if the director did not
believe, as to the non-expertised portion of the prospectus, that a
representation is false or misleading, and if the director conducted a
reasonable





                                      -56-
<PAGE>   58
investigation so as to provide reasonable grounds for belief that there had
been no misrepresentation (the due diligence defense).

         A director of the Company is also subject to potential liability under
the Business Corporations Act "Yukon" ("YBCA").  The YBCA requires every
director of a corporation in exercising the director's power and discharging
the director's duties to act honestly and in good faith with a view to the best
interests of the corporation.  In addition, every director of a corporation is
required in exercising his or her powers and discharging his or her duties to
exercise the care, diligence and skill that a reasonably prudent person would
exercise in comparable circumstances.  Failure to meet these duties will result
in a director becoming liable for actions taken on behalf of the corporation.
A director may be indemnified by a corporation against all costs, charges and
expenses, including an amount paid to settle an action or satisfy a judgment,
reasonably incurred by the director in respect of any civil, criminal or
administrative action or proceeding to which the director is made a party by
reason of being or having been a director of the corporation, if the director
acted honestly and in good faith with a view to the best interests of the
corporation.

royalty, oil payments and other nonoperating interests.

PRODUCTIVE WELL.  A well that is producing oil or gas or that is capable of
production in paying quantities.

NON-PRODUCING RESERVES.  Proved Developed Reserves that consist of (i) proved
reserves from wells which have been completed and tested but are not producing
due to lack of market or minor completion problems which are expected to be
corrected and (ii) proved reserves currently behind the pipe in existing wells
and which are expected to be productive due to both the well log
characteristics and analogous production in the immediate vicinity of the
wells.

different formation or producing horizon from that in which the well was
previously completed.

RESERVE LIFE.  The estimated productive life of a proved reservoir based upon
the economic limit of such reservoir producing hydrocarbons in paying
quantities assuming certain price and cost parameters.  For purposes of this
Prospectus, reserve life is calculated by dividing the Proved Reserves (on an
Mcfe basis) at the end of the period by projected production volumes for the
next 12 months.

discounted future net cash flows from each of the properties at June 30, 1997,
or as otherwise indicated.  Net cash flow is defined as net revenues less,
after deducting production and ad valorem taxes, future capital costs and
operating expenses, but before deducting federal income taxes.  As required by
rules of the Commission, the future net cash flows have been discounted at





                                      -60-
<PAGE>   62
an annual rate of 10% to determine their "present value." The present value is
shown to indicate the effect of time on the value of the revenue stream and
should not be construed as being the fair market value of the properties.  In
accordance with Commission rules, estimates have been made using constant oil
and gas prices and operating costs, at June 30, 1997, or as otherwise
indicated.

UNDEVELOPED ACREAGE.  Lease acreage on which wells have not been drilled or
completed to a point that would permit the production of commercial quantities
of oil and gas regardless of whether such acreage contains proved reserves.

WORKING INTEREST.  The operating interest that gives the owner the right to
drill, produce and conduct operating activities on the property and a share of
production, subject to all royalties, overriding royalties and other burdens
and to all costs of exploration, development and operations and all risks in
connection therewith.

                          INDEPENDENT AUDITOR'S REPORT



Board of Directors
Cotton Valley Resources Corporation
Dallas, Texas


We have audited the accompanying consolidated balance sheets of Cotton Valley
Resources Corporation and subsidiaries (a development stage company) as of June
30, 1997 and 1996, and the related consolidated statements of operations,
stockholders' equity and cash flows for the years ended June 30, 1997 and 1996,
and the period from February 15, 1995 (date of incorporation) to June 30, 1995
and the period from February 15, 1995  to June 30, 1997.  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, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of the Company as of
June 30, 1997 and 1996, and the results of its operations and its cash flows
for the years ended June 30, 1997 and 1996, the period from February 15, 1995
(date of incorporation) to June 30, 1995 and the period from February 15, 1995
to June 30, 1997 in accordance with generally accepted accounting principles.

The carrying value of the Company's oil and gas properties is supported
primarily by proved undeveloped reserves.

                          (Expressed in U.S. Dollars)


1.  NATURE OF OPERATIONS

    The Company was incorporated under the laws of Ontario as Cotton Valley
    Energy Limited (CVEL) on February 15, 1995.  It acquired all of the shares
    of Cotton Valley Energy Corporation (CVEC), a Nevada corporation, on June
    30, 1995 in a one-for-one share and warrant exchange. CVEC was also
    incorporated in February 1995. CVEL had no substantive activity, so the
    acquisition of CVEC was accounted for as a recapitalization of CVEL with
    the net assets of CVEC.  These consolidated financial statements have been
    prepared as if the Company had acquired CVEC at the Company's inception.

    The Company also owns 100% of the outstanding shares of Mustang Oil Field
    Equipment Co., a Nevada corporation that was formed to conduct used oil
    field equipment refurbishing and trading activities, and Cotton Valley
    Operating Company, a Texas corporation formed to operate oil and gas wells.
    Neither of the subsidiaries had commenced operations as of June 30,  1997.
    In addition, the Company owns 100% of Cotton Valley Energy, Inc., which was
    formed in 1997 to complete the Alden acquisition (see Note 3).
    Intercompany accounts and transactions are eliminated in consolidation.

    On June 14, 1996, the Company merged with Arjon Enterprises, Inc. (Arjon),
    an Ontario corporation and reporting issuer in Ontario.  As a result of
    that merger the Company's name was changed to Cotton Valley Resources
    Corporation and a new capital structure was established.  Transactions in
    the accompanying financial statements are reflected as if the resulting
    capital structure was in existence since inception.  Arjon had no business
    activities and its only asset consisted of convertible debentures of the
    Company in the principal amount of $146,300.  The Company accounted for the
    transaction as an issuance of stock for the net monetary assets of Arjon
    accompanied by a recapitalization.  Former Arjon shareholders received
    686,551 common shares (representing approximately 7.5% of the then
    outstanding common shares) of the Company.

    The Company is in the development stage and has not had material revenues
    from operations through June 30, 1997.  The Company's planned principal
    business activity is to acquire, explore, and develop oil and gas
    properties.  The Company also intends to refurbish and trade in used oil
    field equipment.

    The recoverability of amounts capitalized for oil and gas properties is
    dependent upon the identification of economically recoverable reserves,
    together with obtaining the necessary financing to exploit such reserves
    and the achievement of profitable operations.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Oil and Gas Properties

    The Company follows the full-cost method of accounting for oil and gas
    properties.  Accordingly, all costs associated with acquisition,
    exploration and development of oil and gas reserves, including directly
    related overhead costs, are capitalized into a "full-cost pool."

    All capitalized costs of oil and gas properties, including the estimated
    future costs to develop proved reserves, are amortized on the
    unit-of-production  method using estimates of proved reserves.  Costs
    directly associated

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           (Expressed in U.S. Dollars)


    with the acquisition and evaluation of unproved properties are excluded
    from the amortization base until the related properties are evaluated.
    Such unproved properties are assessed periodically and a provision for
    impairment is made to the full-cost amortization base when appropriate.
    Sales of oil and gas properties are credited to the full-cost pool unless
    the sale would have a significant effect on the amortization rate.
    Abandonments of properties are accounted for as adjustments to capitalized
    costs with no loss recognized.

    The net capitalized costs are subject to a "ceiling test," which limits
    such costs to the aggregate of the estimated present value of future net
    revenues from proved reserves discounted at ten percent based on current
    economic and operating conditions.

    Revenue Recognition

    Revenue is accrued and recognized in the month the oil and gas is produced
    and sold.

    Office Equipment

    Office equipment is recorded at cost and depreciated on a straight-line
    basis over the estimated useful lives of the assets, which range from three
    to five years.

    Foreign Currency Translation

    The Company's assets and principal activities are in the United States and
    its functional currency is the U.S.  dollar.  The effects of exchange rate
    changes on transactions denominated in Canadian dollars or other currencies
    are charged to operations. Foreign exchange gains or losses were
    insignificant for all periods presented.

    Income Taxes

    Income taxes are provided for the tax effects of transactions reported in
    the financial statements and consist of taxes currently due, if any, plus
    net deferred taxes related primarily to differences between the bases of
    assets and liabilities for financial and income tax reporting.  Deferred
    tax assets and liabilities represent the future tax return consequences of
    those differences, which will either be taxable or deductible when the
    assets and liabilities are recovered or settled.  Deferred tax assets
    include recognition of operating losses that are available to offset future
    taxable income and tax credits that are available to offset future income
    taxes.  Valuation allowances are recognized to limit recognition of
    deferred tax assets where appropriate.  Such allowances may be reversed
    when circumstances provide evidence that the deferred tax assets will more
    likely than not be realized.

    Deferred Site Restoration

    A provision is established for estimated future costs of site restoration
    of oil and gas production interests, including the removal of production
    facilities at the end of their useful life.  Costs are based on
    management's estimates of the anticipated method and extent of site
    restoration.  The annual charge is determined on the same basis as the
    depletion and amortization of the underlying asset.

    Net Loss Per Share

    Per share information is based on the weighted average number of common
    stock and common stock equivalent shares outstanding. As required by the
    Securities and Exchange Commission rules, all warrants,

                          (Expressed in U.S. Dollars)


    options, and shares issued within a year prior to the initial filing of a
    registration statement are assumed to be outstanding for each year
    presented for purposes of the loss per share calculation.

    Cash Flow Statement

    For purposes of the statement of cash flows, the Company considers all
    highly liquid debt instruments purchased with an original maturity of three
    months or less to be cash equivalents.

    Stock-Based Compensation

    Statement of Financial Accounting Standards No. 123 - Accounting for
    Stock-Based Compensation (SFAS 123), which was effective for the Company
    beginning with its 1997 fiscal year, requires recognition of compensation
    expense for grants of stock, stock options, and other equity instruments
    based on fair value.  If the grants are to employees, companies may elect
    to disclose only the pro forma effect of such grants on net income and
    earnings per share in the notes to financial statements and continue to
    account for the grants pursuant to APB Opinion No. 25, "Accounting for
    Stock Issued to Employees".  The Company has elected the pro forma
    disclosure alternative for employee grants.

    Use of Estimates

    The preparation of the Company's consolidated financial statements in
    conformity with generally accepted accounting principles requires the
    Company to make estimates and assumptions that affect the amounts reported
    in these financial statements and accompanying notes.  Actual results could
    differ from those estimates.  Significant assumptions are required in the
    valuation of proved oil and gas reserves, which as described above may
    affect the amount at which oil and gas properties are recorded. It is at
    least reasonably possible those estimates could be revised in the near term
    and those revisions could be material.

3.  OIL AND GAS PROPERTIES

    Cheneyboro Field

    The Company acquired approximately 5,000 net acres of oil and gas leases in
    the Cheneyboro Field of Navarro County, Texas during fiscal years 1995 and
    1996.  The Company issued 3,252,533 common shares, granted 406,567 Class A
    warrants (see Note 5), and paid $500,000 in cash and a promissory note of
    $586,049 as consideration.  The stock was recorded at $5,935,281, based on
    the estimated fair value of the properties.  The Company determined fair
    value by reference to an independent engineering firm's reserve report.  In
    fiscal year 1997, an additional 1,500 net acres were acquired.  During the
    year ended June 30, 1996, the Company capitalized management fees and
    salaries of $195,476 directly related to the acquisition and proposed
    development of the property.  No such costs were capitalized in the year
    ended June 30, 1997.

    Movico Field, Mobile County, Alabama

    The Company acquired an option to acquire an interest in oil and gas leases
    in the Movico Field of Mobile County, Alabama in fiscal year 1995.
    Consideration included 77,928 Class A warrants and  623,424 common shares,
    which were recorded at $1,137,635, based on the estimated fair value of the
    properties.  The Company determined fair value by reference to an
    independent engineering firm's reserve report.  In June 1997, the Company
    transferred the option to the company from which the Sword Unit option (see
    below) was acquired in exchange for a reduction in that option price.

                          (Expressed in U.S. Dollars)


    Sword Unit, Offshore Santa Barbara, California

    The Company has entered into option agreements to acquire a working
    interest in the Sword Unit, Offshore Santa Barbara, California.  The
    Company paid $400,000 in fiscal year 1996 to acquire the option.  In
    addition, the Company agreed to pay an additional $125,000 in fiscal year
    1997 to settle a contingent liability of up to $1,000,000 due upon closing
    the acquisition.  To complete the option and acquire the working interest,
    the Company was initially required to pay $12,000,000 in cash and
    marketable securities (including the $1,000,000 referred to above) on
    closing sometime in 1997.  In June 1997, in connection with the transfer of
    the Movico property described above, the requirement was reduced to
    $8,000,000, of which $2,000,000 may be in the Company's stock at the
    election of the other party.  The Company is also required to participate
    in a $4,000,000 letter of credit related to the abandonment of two existing
    wells if it acquires the working interest.

    Alden Properties, Caddo County, Oklahoma

    In fiscal year 1997, the Company acquired an interest in the Alden
    properties for $390,000.

    Aspen Energy Corporation

    Subsequent to June 30, 1997, the Company acquired Aspen Energy Corporation
    as described in Note 9.

4.  NOTES PAYABLE AND LONG-TERM DEBT

    The Company has a $579,000 note payable at June 30, 1997 to a company that
    provided investor relations services to the Company and owns stock in the
    Company.  The note bears interest at 9% and is due October 24, 1997.  The
    note is collateralized by the Company's rights to certain oil and gas
    properties and is convertible into the Company's common stock at $1.67 per
    share.  Warrants to purchase 161,351 shares at $2.08 through April 30, 2002
    were also granted in connection with this transaction.  The estimated fair
    value of the warrants at the time of grant of $124,000 has been accounted
    for as a discount to the note.

    The Company has promissory notes payable totaling $200,000 and $586,049 at
    June 30, 1997 and 1996, respectively, for the unpaid purchase price of the
    Cheneyboro oil and gas properties (see Note 3).  The notes are
    collateralized by the properties and are due July 17, 1997. Interest is
    payable quarterly at 12%.  In June 1997, the creditor converted $349,000 of
    the balance to common stock.  In connection with the conversion, the
    creditor was granted warrants to purchase 302,191 shares as described in
    Note 5.

5.  STOCKHOLDERS' EQUITY

    The Company has an unlimited number of preferred shares authorized, which
    may be issued in series and include such rights and preferences as
    authorized by the board of directors.  The board of directors has
    authorized the issuance of up to 2,000,000 shares of 8% Cumulative
    Convertible Preferred Stock.  No such shares have been issued as of June
    30, 1997.  If the shares were to be issued, holders of the Preferred Stock
    would be entitled to two votes per share on all matters submitted to a vote
    of the Company's shareholders.  In addition, such holders would be entitled
    to receive cumulative dividends at the rate of 8% per annum, payable at the
    election of the Company in cash or in shares of common stock.  Holders of
    the Preferred Stock would have a liquidation preference, limited to $6.00
    per share of Preferred Stock; and each outstanding share of Preferred Stock
    would be convertible at any time by the holder into two shares of common
    stock.

                          (Expressed in U.S. Dollars)


    Shortly after incorporation, the Company issued 2,100,000 special shares
    for total cash consideration of $2.00 to officers, which were subsequently
    exchanged for 1,440,000 common shares of the Company.  The special shares
    were issued in exchange for preferred stock which had been issued upon
    incorporation of CVEC and subsequently canceled.

    In connection with the acquisition of oil and gas properties, including a
    property abandoned following its acquisition, the Company granted 518,345
    Class A warrants.  In connection with the issuance of notes payable and
    debentures, the Company granted 112,390 Class A warrants. The Company also
    issued 636,250 Class A warrants in conjunction with a private placement of
    common shares.  Each Class A warrant is a right to purchase one common
    share for $2.00 until December 31, 1997.  None of the Class A warrants had
    been exercised as of June 30, 1997.

    Effective January 31, 1996, each 2.5 outstanding shares of the Company's
    common stock were consolidated into one share and the previously authorized
    unlimited number of special shares were canceled. The financial statements
    reflect the consolidation of common shares as if it occurred on inception
    of the Company.

    In December 1995, the Company issued a total of 300,000 shares of common
    stock to two officers in exchange for services performed from June 1995
    through December 1995.  The shares were recorded at $446,950, which
    represented the estimated value of the shares.

    During the year ended June 30, 1996, the Company granted to senior
    employees options that enable the employees to purchase 800,000 shares of
    the Company's common stock for $1.83 per share until July 1, 2000.  In
    fiscal year 1997, options to purchase an additional 330,000 shares were
    granted directors and employees under substantially the same terms.  The
    Company is authorized to issue shares of common stock under its employee
    stock option plan to employees, officers, directors, consultants and other
    service providers, provided that insiders must not in the aggregate hold
    options exceeding 10% of the outstanding shares.  None of the director and
    employee options had been exercised as of June 30, 1997.

    The Company has granted to the placement agent of the debenture and private
    placement offerings that occurred in fiscal year 1996 three-year options to
    purchase up to 10% of the common shares issued upon conversion of the
    debentures at a price equal to the conversion price.  As a result, the
    agent has the right to buy 37,741 common shares at $1.48 per share until
    August 31, 1998; 73,739 common shares at $2.00 per share until December 31,
    1997; and 125,000 common shares at $1.64 per share until April 30, 1998.
    Certain of these warrants were exercised in fiscal year 1997.

    In conjunction with the merger with Arjon, a total of 431,755 common shares
    are issuable to former Arjon shareholders for Arjon warrants in existence
    prior to the merger.  These shares are issuable as follows: 333,334 common
    shares until December 31, 1998 at an exercise price of $0.48 per share and
    98,421 common shares at an exercise price of $1.64 per share until December
    31, 1997.  Certain of these warrants were exercised in fiscal year 1997.

    In November 1996, the Company entered into an agreement to obtain certain
    investor relations services.  The other party was granted 1,490,000 shares
    of the Company's common stock as non-forfeitable compensation.

    The stock was recorded at $1,087,800, based on the Company's stock price at
    the date of the agreement.  The other party was required to acquire 500,000
    units, with each unit consisting of one share of the Company's common stock
    and a warrant to purchase one share for $0.80 through November 2001, for
    $375,000.  As of June 30, 1997, the Company had received payment for the
    units, but 140,000 of the shares remained unissued. This has been recorded
    as common stock subscribed in the accompanying financial statements.  None
    of the warrants had been exercised as of June 30, 1997.  The estimated fair
    value of the warrants at the time of grant of $199,000 has been recorded as
    general and administrative expense.

    In fiscal year 1997, additional warrants were granted as set forth below.
    None of these warrants had been exercised as of June 30, 1997.

</TABLE>

    Fair value of warrants granted to non-employees for services or in
    connection with debt transactions during the year ended June 30, 1997 was
    determined using the Black-Scholes option pricing model.  Significant
    assumptions included a risk-free interest rate of 5.9%, expected volatility
    of 102%, and that no dividends would be declared during the expected term
    of the options.  The weighted average contractual term of the warrants was
    approximately 5.0 years compared to a weighted average expected term of 2.0
    years.  The estimated fair value of warrants described above amounted to
    $323,000 of which $124,000 is recorded as a debt issuance cost in the
    balance sheet and $199,000 is recorded as general and administrative
    expense in the statement of operations.

    Pro Forma Stock-Based Compensation Disclosures - The Company applies APB
    Opinion 25 and related interpretations in accounting for its stock options
    and warrants which are granted to employees.  Accordingly, compensation
    cost has not been recognized for grants of options and warrants to
    employees and directors unless the exercise prices were less than the fair
    value of the Company's common stock on the grant dates.  Had compensation
    cost been determined based on the fair value at the grant dates for awards
    under those plans consistent with the method of FASB 123, the Company's net
    loss and loss per share would have been increased to the pro forma amounts
    indicated below.

6.  RELATED PARTY TRANSACTIONS

    During the year ended June 30, 1996 and the period from February 15, 1995
    to June 30, 1995, the Company paid management fees in lieu of salaries to
    two corporations controlled by senior officers of the Company, aggregating
    $160,000 and $50,000, respectively.  In addition, the Company has received
    advances from these two companies, net of repayments, totaling  $139,710
    and $171,709 at June 30, 1997 and 1996, respectively.  The advances are
    unsecured, without interest and are due after June 30, 1998.

    The difference from the expected income tax benefit for the year ended June
    30, 1997 at the statutory federal tax rated of 34% and the actual income
    tax benefit is primarily the result of amounts related to the estimated
    value of warrants that were expensed for purposes of the financial
    statements, but are not deductible for

    income tax purposes.  At June 30, 1997, the Company has available net
    operating loss carryforwards of approximately $4,000,000  to reduce future
    taxable income.  These carryforwards expire from 2002 to 2004.

8.  CONCENTRATION OF CREDIT RISK AND  FAIR VALUE OF FINANCIAL INSTRUMENTS

    At June 30, 1997 and 1996, the Company had deposits in one financial
    institution that were approximately $543,000 and $700,000, respectively in
    excess of FDIC insurance limits.

    The Company's financial instruments at June 30, 1997 and 1996 are cash,
    accrued oil and gas sales, accounts payable, long-term debt and advances
    from related parties.  Management believes the fair market values of cash,
    accrued oil and gas sales and accounts payable approximate carrying values
    due to the short-term nature of these instruments.  Management has
    estimated the fair values of long-term debt and advances from related
    parties based on expected discounted cash flows and believes the fair
    values are not materially different than carrying values.

9.  SUBSEQUENT EVENTS

    On July 31, 1997, effective June 30, 1997, the Company acquired 100% of
    Aspen Energy Corporation, an oil and gas company, for $200,000 in cash, a
    $300,000 promissory note payable in two installments through January 1998
    and 2,511,317 shares of the Company's common stock.  In addition, the
    shareholders of Aspen agreed to deliver 270,000 of the shares they received
    in the transaction back to Aspen in satisfaction of obligations owed by
    such shareholders to Aspen in the amount of $425,000.

    In July 1997, the Company entered into a letter agreement with an
    investment banking firm to arrange a sale of part or all of the Company or
    a strategic alliance with a larger company.  The investment banking firm
    was granted exclusive representation rights for a period of nine months and
    will receive a fee, if the transaction is completed, varying from 3% to 10%
    of the transaction size.

    In July 1997, the Company initiated a private placement of its common stock
    and of 15% two-year notes.  Through September 15, 1997, the Company had
    sold 272,700 shares for net proceeds of $454,500 in the stock placement and
    raised $125,000 in the note offering.  In addition, warrants to purchase
    approximately 433,000  shares of stock had been exercised for proceeds of
    $866,000 from July 1, 1997 through September 15, 1997.

11. OIL AND GAS RESERVE INFORMATION (UNAUDITED)

    Proved oil and gas reserves are the estimated quantities of crude oil,
    condensate and natural gas which geological and engineering data
    demonstrate with reasonable certainty to be recoverable in future years
    from known reservoirs under existing economic and operating conditions.
    Proved developed oil and gas reserves are reserves that can be expected to
    be recovered through existing wells with existing equipment and operating
    methods.  The following estimated net interests in proved reserves are
    based upon subjective  engineering judgments and may be affected by the
    limitations inherent in such estimation.  The process of estimating
    reserves is subject to continual revision as additional information becomes
    available as a result of drilling, testing, reservoir studies and
    production history.  There can be no assurance that such estimates will not
    be materially revised in subsequent periods.

    The Company emphasizes that reserve estimates of new discoveries or
    undeveloped properties are more imprecise than those of producing oil and
    gas properties.  The Company's reserves are substantially from undeveloped
    properties.  Accordingly, these estimates are expected to change materially
    as future information becomes available.  The Company's reserves were
    estimated by independent petroleum engineers.  All of the Company's
    reserves are located onshore in the continental United States.  The
    recoverability of the proved undeveloped reserves is dependent upon
    obtaining financing to exploit the reserves.

    The following table sets forth proved oil and gas reserves at June 30,
    1997, 1996 and 1995 together with changes therein:

    The standardized measure of discounted future net cash flows at June 30,
    1997, 1996 and 1995 relating to proved oil and gas reserves is set forth
    below.  The assumptions used to compute the standardized measure are those
    prescribed by the Financial Accounting Standards Board and as such, do not
    necessarily reflect the Company's expectations of actual revenues to be
    derived from those reserves nor their present worth.  The limitations
    inherent in the reserve quantity estimation process described above are
    equally applicable to the standardized measure computations since these
    estimates are the basis for the valuation process.

                         NOTES TO FINANCIAL STATEMENTS
                          (Expressed in U.S. Dollars)

1.  NATURE OF BUSINESS AND BASIS OF PREPARATION AND PRESENTATION

    Cotton Valley Resources Corporation (the Company) has its primary business
    focus in the acquisition of ownership interests in, and the production of
    oil and gas from, existing oil and gas fields that indicate a potential for
    increased production through rehabilitation. The Company also purchases,
    repairs, rehabilitates and sells used oilfield production equipment. Also,
    beginning in February, 1998, the Company provides well servicing and
    horizontal drilling services on its own properties and for other operators.
    The Company was considered to be in the development stage until August 1,
    1997.

    The condensed consolidated financial statements of Cotton Valley Resources
    Corporation and subsidiaries (collectively Cotton Valley) included herein
    have been prepared by management of Cotton Valley without audit. Certain
    information and footnote disclosures normally included in financial
    statements prepared in accordance with generally accepted accounting
    principles have been condensed or omitted, since management  believes that
    the disclosures included are adequate to make the information presented not
    misleading. In the opinion of management, the condensed consolidated
    financial statements include all adjustments consisting of normal recurring
    adjustments necessary to present fairly the financial position, results of
    operations, and cash flows as of the dates and for the periods presented.
    These condensed consolidated financial statements should be read in
    conjunction with the consolidated financial statements and the notes
    thereto included for the fiscal year ended June 30, 1997.

    Restricted Cash

    Restricted cash at December 31, 1997 represents the unused funding of the
    Convertible Debenture (see Note 7). This cash may be used for working
    capital and other purposes upon submission of collateral under the terms of
    the agreement.

    Net Profit Per Share

    In February 1997, the Financial Accounting Standards Board issued Statement
    of Financial Accounting Standards No. 128, Earnings Per Share ("SFAS
    128"). SFAS 128 requires companies with complex capital structures that
    have publicly held common stock or common stock equivalents to present both
    basic and diluted earnings per share ("EPS") on the face of the income
    statement. The presentation of basic EPS replaces the presentation of
    primary EPS currently required by Accounting Principles Board Opinion No.
    15 ("APB No. 15"). Basic EPS is calculated as income available to common
    stockholders divided by the weighted average number of common shares
    outstanding during the period. Diluted EPS is calculated using the "if
    converted" method for convertible securities and the treasury stock method
    for options and warrants as prescribed by APB No. 15. This statement is
    effective for financial statements issued for interim and annual periods
    ending after December 15, 1997. The Company adopted SFAS 128 as of
    December 31, 1997 for the period ended December 31, 1997 and all prior
    periods. The adoption of SFAS 128 has not had a significant impact on the
    Company's reported EPS to date.

2.  COMMON STOCK

    During the six months ended December 31, 1997, Cotton Valley issued shares
    of common stock to four individuals to purchase Aspen Energy Corporation
    (Aspen) (see Note 3), issued 272,700 shares of common

    270,000 shares were returned to Cotton Valley by two Aspen shareholders in
    settlement of notes payable to Aspen in the amount of $425,000.  The
    acquisition was accounted for as a purchase and the operations of Aspen are
    consolidated with the Company beginning on August 1, 1997.  The following
    unaudited pro forma information for the six month period ended December 31,
    1996 has been prepared as if Aspen had been acquired on July 1, 1996:

7.  SECURED CONVERTIBLE DEBENTURES

    During the six month period ended December 31, 1997, Cotton Valley sold
    $4,320,000 of 7% Secured Convertible Debentures to a group of private
    investors.  Portions of the proceeds were used to complete the acquisition
    of the well service rigs and related equipment discussed in Note 6.  The
    debentures are due December 31, 2001 and are collateralized by the well
    service rigs and related equipment and by restricted cash with a balance of
    $2,570,820 at December 31, 1997.  The debentures are convertible into
    shares of common stock and warrants to purchase common stock.  The
    debentures are convertible at the lesser of $2.70

    per share or 90% of the average of the three lowest closing bid prices
    during the ten trading days prior to the notice of conversion.  If the
    conversion price is below $1.80 per share, no more than 10% of the
    debentures may be tendered for conversion during a thirty day period.  The
    warrants are exercisable at prices related to the market price at the time
    of conversion.  Costs of approximately $419,000 related to the debenture
    offering have been capitalized and will be amortized over the life of the
    notes.

8.  SUBSEQUENT EVENTS

    In January 1998, the Company completed the purchase of certain oil and gas
    interests in the Zama Lake area in Alberta, Canada (the "Zama Property").
    The purchase price was approximately $6,900,000.  Immediately following the
    purchase of the Zama Property, the Company sold all of its interests to a
    third party for approximately $7,500,000.

    Also in January 1998, the Company and Phillips Petroleum Company
    ("Phillips") entered into an agreement for the purchase by the Company of
    all of Phillips' interests in certain oil and gas leases (the "Leases"),
    including the wells, equipment and personal property located on the Leases,
    in the East Binger Unit, Caddo County, Oklahoma for $4,000,000.  Closing of
    the transaction is subject to the Company obtaining financing for the
    purchase price and is currently scheduled for May 31, 1998.  The completion
    of the transaction is further subject to title examinations and other
    conditions.

    In February 1998 the stockholders of the Company approved the 1997 Stock
    Compensation Plan (the "1997 Plan") and reserved 1,400,000 shares of Common
    Stock for issuance under the plan.  Eligible participants in the 1997 Plan
    include full-time employees, directors (other than Non-Employee Directors)
    and advisors of the Company and its subsidiaries.

    Also in February 1998, the stockholders of the Company approved the
    Non-Employee Directors Stock Option Plan (the "Directors Plan") and
    reserved for issuance 200,000 shares of Common Stock for issuance under the

              UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS


The following unaudited pro forma combined statement of operations is derived
from the financial statements of Cotton Valley Resources Corporation (the
Company) and Aspen Energy Corporation.  In July 1997, the Company acquired 100%
of the common stock of Aspen for a purchase price consisting of $200,000 in
cash, $300,000 non-interest bearing six month notes and 2,241,000 shares of the
Company's common stock (net of 270,000 shares transferred back to the Company
to retire $425,000 of loans from Aspen to the Aspen stockholders).  The
Unaudited Pro Forma Income Statement for the year ended June 30, 1997 has been
prepared assuming the acquisition had been consummated as of the beginning of
the fiscal year.

The unaudited combined pro forma financial statements should be read in
conjunction with the notes thereto and with the financial statements of the
Company as included in its Form 10-KSB and the financial statements of Aspen
included herein.

The unaudited combined pro forma financial statements are not indicative of the
financial position or results of operations of the Company which would actually
have occurred if the acquisition of Aspen had occurred at the date presented or
which may be obtained in the future.  In addition, future results may vary
significantly from the results reflected in such statements due to normal oil
and gas production declines, changes in prices paid for oil and gas, future
acquisitions, drilling activity and other factors.

         NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS
                        For the Year Ended June 30, 1997


(1)     Adjustments to add Aspen's operations for the six months ended June 30,
        1997, and deduct Aspen's operations for the six months ended June 30,
        1996, to its operations for the year ended December 31, 1996.  The
        adjustment is necessary to record Aspen's operations for the year ended
        June 30, 1997 as if Aspen had been acquired by Cotton Valley at the
        beginning of that fiscal year.

(2)     Adjustment to depletion expense to record the depletion expense as if
        Aspen had been acquired on July 1, 1996.

(3)     To record imputed interest expense on the $300,000 six month note
        payable issued the sellers of Aspen.

(4)     To record the effect of the pro forma adjustments on the income tax
        benefit.

(5)     To record the net shares issued in the acquisition as if they had been
        issued on July 1, 1996.

           (The period subsequent to December 31, 1996 is unaudited.)

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Nature of Operations

    Aspen Energy Corporation (the "Company") is engaged in the acquisition,
    operation and development of oil and gas properties, which are located
    primarily in Texas, Oklahoma and Utah as of December 31, 1996.

    Cash and Cash Equivalents

    The Company considers all highly liquid debt instruments purchased with a
    maturity of three months or less to be cash equivalents.

    Revenue Recognition

    The Company recognizes revenue as oil or gas is produced and sold.

    Oil and Gas Producing Operations

    The Company follows the full cost method of accounting for oil and gas
    properties.  Accordingly, all costs associated with acquisition,
    exploration, and development of oil and gas reserves, including directly
    related overhead costs, are capitalized in the full cost pool.  All
    capitalized costs of oil and gas properties, including the estimated future
    costs to develop proved reserves, are amortized on the unit-of-production
    method using estimates of proved reserves.

    In addition, capitalized costs are subject to a "ceiling test", which
    basically limits such costs to the aggregate of the estimated present
    value, discounted at a 10% interest rate, of future net revenues from
    proved reserves, based on current economic and operating conditions, plus
    the lower of cost or fair market value of unproved properties.

    Sales of proved and unproved properties are accounted for as adjustments of
    capitalized costs with no gain or loss recognized, unless such adjustments
    would significantly alter the relationship between capitalized costs and
    proved reserves of oil and gas, in which case the gain or loss is
    recognized in income.  Abondonments of properties are accounted for as
    adjustments of capitalized costs with no loss recognized.

    Income Taxes

    Income taxes are provided for the tax effects of transactions reported in
    the financial statements and consist of taxes currently due, if any, plus
    net deferred taxes related primarily to differences between the bases of
    assets and liabilities for financial and income tax reporting.  Deferred
    tax assets and liabilities represent the future tax return consequences of
    those differences, which will either be taxable or deductible when the
    assets and liabilities are recovered or settled.  Deferred tax assets
    include recognition of operating losses that are available to offset future
    taxable income and tax credits that are available to offset future income
    taxes.  Valuation allowances are recognized to limit recognition of
    deferred tax assets where appropriate.  Such allowances may be reversed
    when circumstances provide evidence that the deferred tax assets will more
    likely than not be realized.

    Financial Investments

    The Company's financial instruments are cash, accounts receivable and
    payable and loans receivable from related parties.  Management estimates
    that the fair values of these financial instruments approximate their
    carrying values due to their short-term nature.

                         NOTES TO FINANCIAL STATEMENTS
           (The period subsequent to December 31, 1996 is unaudited.)

    Loss Per Share

    Loss per share is computed based on the weighted average number of shares
    outstanding during the period.

    Use of Estimates and Certain Significant Estimates

    The preparation of the Company's financial statements in conformity with
    generally accepted accounting principles requires the Company's management
    to make estimates and assumptions that affect the amounts reported in these
    financial statements and accompanying notes.  Actual results could differ
    from those estimates.  Significant assumptions are required in the
    valuation of proved oil and gas reserves, which as described above may
    affect the amount at which oil and gas properties are recorded.  It is at
    least reasonably possible those estimates could be revised in the near term
    and those revisions could be material.

    Unaudited Information

    The balance sheet as of June 30, 1997 and the statements of operations for
    the six month periods ended June 30, 1997 and 1996 were taken from the
    Company's books and records without audit.  However, in the opinion of
    management, such information includes all adjustments which are necessary
    to properly reflect the financial position of the Company as of June 30,
    1997 and the results of its operations for the six months ended June 30,
    1997 and 1996.

2.  LOANS RECEIVABLE FROM RELATED PARTIES

    The Company had loans receivable from stockholders for cash advances that
    totaled $425,000 and $345,000 at June 30, 1997 and December 31, 1996,
    respectively.  The loans were unsecured, non-interest bearing and contained
    no specific repayment terms.  The loans were subsequently retired as
    described in Note 6, and have been classified as a reduction of
    stockholders' equity in the accompanying balance sheets.

3.  PRODUCTION PAYMENT LIABILITY

    The Company has a liability associated with the purchase of an oil and gas
    property that requires payment to the creditor of 25% of the net revenue
    earned from the property each month.  The liability does not have a stated
    interest rate. Therefore, interest was imputed at 10%.  The balance at June
    30, 1997 and December 31, 1996 is $62,791 and $65,800, respectively.

4.  CONCENTRATION OF CREDIT RISK AND SALES REVENUE

    The Company had the following concentrations in volume of oil and gas sales
    revenue in 1996:

<TABLE>
<CAPTION>
                   Customer
                   --------
                      <S>                  <C>
                      A                     43%
                      B                     29%
                      C                     22%
</TABLE>

    Additionally, the three customers above accounted for a substantial
    majority of accrued oil and gas sales as of December 31, 1996.

    The Company periodically maintains balances in financial institutions in
    excess of FDIC insurance limits.  The Company had a balance in one
    institution at December 31, 1996 that was $276,677 in excess of such limit.

           (The period subsequent to December 31, 1996 is unaudited.)

5.  INCOME TAXES

    The Company's income tax benefit of $237,143 for the year ended December
    31, 1996 was composed entirely of deferred taxes.

    The Company's deferred tax liability of $320,514 at December 31, 1996 was
    the result of different bases for book and tax purposes of the Company's
    oil and gas properties.

6.  SUBSEQUENT EVENT

    In 1997, 100% of the Company's stock was sold to Cotton Valley Resources
    Corporation.  In connection with that transaction, the loans receivable
    from related parties (Note 2) were retired.

7.  SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED)

    The following table sets forth certain information with respect to the oil
    and gas producing activities of the Company:

<TABLE>

</TABLE>

    The following table, based on information prepared by independent petroleum
    engineers, summarizes changes in the estimates of the Company's net
    interest in total proved reserves of crude oil and condensate and natural
    gas, all of which are domestic reserves:

</TABLE>

    All of the above reserves were classified as proved undeveloped and are
    located in the continental United States.  The Company has production on
    the property, but intends to convert the property to a waterflood project,
    which would entail conversion of the producing wells to injection wells.
    The Company also has other, relatively minor, producing properties for
    which reserve reports were not prepared.  To develop the Company's reserves
    will require a substantial investment of capital, which is currently not
    available.  Therefore, the Company will either have to raise additional
    capital or sell interests in its property, which would reduce the Company's
    net interest in its reserves.

           (The period subsequent to December 31, 1996 is unaudited.)

    Proved oil and gas reserves are the estimated quantities of crude oil,
    condensate and natural gas which_geological and engineering data
    demonstrate with reasonable certainty to be recoverable in future years
    from known reservoirs under existing economic and operating conditions.
    Proved developed oil and gas reserves are reserves that can be expected to
    be recovered through existing wells with existing equipment and operating
    methods.  The above estimated net interests in proved reserves are based
    upon subjective engineering judgments and may be affected by the
    limitations inherent in such estimation.  The process of estimating
    reserves is subject to continual revision as additional information becomes
    available as a result of drilling, testing, reservoir studies and
    production history, especially in connection with the Company as all the
    reserves are proved undeveloped.  There can be no assurance that such
    estimates will not be materially revised in subsequent periods.

8.  STANDARDIZED MEASURE OF CHANGES IN FUTURE NET REVENUES (UNAUDITED)

    The standardized measure of discounted future net cash flows at December
    31, 1996, relating to proved oil and gas reserves is set forth below.  The
    assumptions used to compute the standardized measure are those prescribed
    by the Financial Accounting Standards Board and, as such, do not
    necessarily reflect the Company's expectations of actual revenues to be
    derived from those reserves nor their present worth.  The limitations
    inherent in the reserve quantity estimation process are equally applicable
    to the standardized measure computations since these estimates are the
    basis for the valuation process.

ITEM 26.     RECENT SALES OF UNREGISTERED SECURITIES.

         Effective June 14, 1996, the Company, as consideration for the
amalgamation between Cotton Valley Energy Limited and Arjon Enterprises, Inc.
("Arjon"), issued an aggregate of  686,551 shares of Common Stock to the
shareholders of Arjon.  Pursuant to the amalgamation agreement between the
Company, Arjon and its shareholders, the Company acquired the only asset of
Arjon, a Cotton Valley Energy Limited debenture in the amount of $146,300, in
exchange for 686,551 shares of Common Stock.  As a result of the Arjon
amalgamation, the Company's name was changed to Cotton Valley Resources
Corporation and its shares of Common Stock began trading through the Canadian
Dealing Network.  Additionally, 431,755 shares of Common Stock were issued to
Arjon shareholders upon exercise of Arjon Warrants in existence prior to the
amalgamation.  Arjon was a public Canadian company formed more than 50 years
ago to operate a gold mine.  At the time of the amalgamation, Arjon had not
engaged in any business activity for more than 25 years.

         The Arjon/Cotton Valley amalgamation was consummated in accordance
with the laws of the Province of Ontario, Canada.  Documents, as required, were
filed with the Ontario Securities Commission.  A Registration Statement on Form
20-F as filed with the Securities and Exchange Commission in November 1996 was
declared effective by the Commission in January 1997, registering all the then
outstanding shares of Common Stock of the Company.





                                      II-1

         The Company has sold and issued unregistered securities in the
following transactions since the date of the amalgamation:

         a.  THE LIVIAKIS TRANSACTIONS.

         In November 1996, the Company entered into a consulting agreement (the 
"LFC Consulting Agreement") with Liviakis Financial Communications, Inc.
("LFC"). Pursuant to the terms of the LFC Consulting Agreement, the Company sold
to LFC and one of its officers, Robert B. Prag, for $0.75 per unit, 500,000
units, each unit consisting of one share of Common Stock and one stock purchase
warrant (a "Warrant," collectively with one share of Common Stock, a "Unit")
entitling the holder thereof to purchase a share of Common Stock at an exercise
price of $0.80 through November 7, 2001 (a "LFC Warrant").  The Company issued
to LFC 375,000 Units, for which the Company received a promissory note in the
amount of $281,250, and the Company issued to Robert B. Prag 125,000 Units, for
which the Company received a promissory note in the amount of $93,750.  Both
promissory notes were paid off within 90 days of issue.  As further
consideration for services performed by LFC pursuant to the terms of the LFC
Consulting Agreement, the Company issued 1,490,000 shares of Common Stock to
LFC.  The stock issuance was recorded at $1,087,800 based on the Company's stock
price on the Canadian Dealing Network ("CDN"). Additionally, in February 1998,
the Company issued to LFC warrants to purchase 100,000 shares of Common Stock
exercisable at $3.50 per share until December 31, 2000 (the "LFC Mustang
Warrants"), as additional compensation for LFC's assistance to the Company in
completing acquisitions and other financings during calendar 1997. LFC directed
the Company to issue to Robert B. Prag 25,000 of the LFC Mustang Warrants.


         Effective June 24, 1997, the Company executed a convertible secured
promissory note (the "LFC Note") to LFC whereby the Company promised to pay to
LFC on or before the Maturity Date of the LFC Note, the sum of $1,000,000 or so
much thereof as may have been advanced, whichever is less, plus interest of 9%
per annum.  Pursuant to the terms of the LFC Note, LFC immediately advanced to
the Company $579,000 and the Company issued to LFC 161,351 Common Stock
purchase warrants at an exercise price of $2.08 per share until April  3, 2002
(the "Liviakis Warrants").  The outstanding principal amount of the LFC Note
together with accrued but unpaid interest were convertible by LFC into shares
of Common Stock at a conversion price of $1.67 per share.  On December 3, 1997,
the Company repaid $479,000 of the principal amount of the LFC Note and all
interest accrued on the LFC Note, and LFC converted the remaining $100,000
principal amount of the LFC Note into 60,000 shares of Common Stock.

         The sale of securities above were made in reliance upon Section 4(2)
of the Securities Act, which provide exemptions for transactions not involving
a public offering.  The Company determined that the purchasers of securities

registration statement under the Securities Act or an exemption from such
registration requirements.

         b.  THE HIBERNIA TRANSACTIONS.

         In a Canadian private placement completed in November 1996 the Company

and two stock purchase warrants (the "Hibernia Warrants"), enabling the holder
thereof to purchase one share of Common Stock at an exercise price of $0.73 per
share through December 31, 1999.  None of the Hibernia Warrants have been
exercised.

         In a private placement of securities completed in January 1996, the
Company issued 200,000 shares of Common Stock and 200,000 warrants to Hibernia
Management Company ("HMC") for total consideration of $164,425.  Each warrant

Stock

<PAGE>   103

Company's Common Stock, of which 270,000 shares were returned to the Company by

Navarro County, Texas (the "Cheneyboro Field").  As partial consideration for
the purchase, the Company issued, in fiscal year 1996, a promissory note dated
July 17, 1997 in the amount of $586,047 to a limited partnership consisting of
HMC, Euro Coach America Corporation and NPCS, Inc.  The outstanding balance of

         f.  PRIVATE OFFERINGS.

             1.  PRIVATE OFFERING OF CONVERTIBLE DEBENTURES COMPLETED ON
                 DECEMBER 30, 1997.

         On December 30, 1997, the Company completed the private placement of
$4,320,000 of its 7% Secured Convertible Debentures ("Convertible Debentures")

limits on rights to convert if the conversion price of the Company's Common
Stock falls below a floor price of $1.80 per share (the "Floor Price").  The
conversion price is the lesser of $2.70 per share or 90% of the average of the
three lowest closing bid prices during the ten trading days prior to the notice
of conversion.  During any thirty-day period, any investor may not tender for
conversion more than 10% of his originally purchased Convertible Debentures at
a conversion price less than the Floor Price.  The Company may elect to redeem
(for a 10% premium) any Convertible Debentures tendered for conversion at any
price below the Floor Price.

         In addition to the usual and customary covenants contained in
convertible debenture agreements of this nature, the Company is required to
reserve shares of Common Stock in an amount not less than 200% of the number of
shares of Common Stock that would be issuable upon conversion in full of the
Convertible Debentures and full exercise of the Debenture Warrants granted
thereunder.  In furtherance of this covenant, the Company is required to seek
stockholder approval of an increase in the Company's authorized shares if
necessary to maintain such reserves.  Furthermore, any holder of Convertible
Debentures shall not be permitted to convert its Convertible Debentures or
exercise its Debenture Warrants to the extent that such conversion or exercise
would result in a beneficial ownership in the Company in excess of 4.999%.  The
Convertible Debenture holders have a right of first

refusal for future financing of the Company under certain conditions.  The
Company has listed an additional 3.2 million shares of its Common Stock on AMEX
for the shares underlying the Convertible Debentures and shares to be issued
upon exercise of the Debenture Warrants.  Although the Company's Registration
Statement includes 3.2 million shares, which the Company currently believes
will provide sufficient shares upon the conversion of the Convertible
Debentures and upon exercise of all the Debenture Warrants, the Company has
reserved for issuance up to 4.8 million shares of its Common Stock to be
issued, if necessary, upon conversion of the Convertible Debentures and up to
1.2 million shares to be issued, if necessary, upon exercise of the Debenture
Warrants.

total consideration of $579,500.  The Company also issued to the WPM Group, an
affiliate of John Malone, P.C., 32,500 WPM Warrants.  The WPM Warrants are
exercisable at $2.08 per share until April 3, 2002.  None of the WPM Warrants
have been exercised.

ITEM 28.     UNDERTAKINGS.

The undersigned registrant hereby undertakes:

         (1) To file, during any period in which it offers or sells securities,
             a post-effective amendment to this registration statement to:  (i)
             include any prospectus required by Section 10(a)(3) of the
             Securities Act; (ii) reflect in the prospectus any facts or events
             which, individually or together, represent a fundamental change in
             the information in the registration statement; and (iii) include
             any additional or changed material information on the plan of
             distribution.  Notwithstanding the foregoing, any increase or
             decrease in the volume of securities offered (if the total dollar
             value of securities offered would not exceed that which was
             registered) and any deviation from the low or high end of the
             estimated maximum offering range may be reflected in the form of
             prospectus filed with the





                                      II-8
<PAGE>   109
             Commission pursuant to Rule 424(b) if, in the aggregate, the
             changes in volume and price represent no more than a 20% change in
             the maximum aggregate offering price set forth in the "Calculation
             of Registration Fee" table in the effective registration
             statement.

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

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

         (4) To provide to the Placement Agent(s) at each closing specified in
             the Selling Agreement certificates in such denominations and
             registered in such names as required by the Placement Agents to
             permit prompt delivery to each purchaser.

         (5) Insofar as indemnification for liabilities arising under the
             Securities Act may be permitted to directors, officers or persons
             controlling the registrant pursuant to the foregoing provisions,
             or otherwise, the registrant has been advised that, in the opinion
             of the Commission, such indemnification is against public policy,
             as expressed in the Securities Act and is, therefore,
             unenforceable.  In the event that a claim for indemnification
             against such liabilities (other than the payment by the registrant
             of expenses incurred or paid by a director, officer or controlling
             person of the registrant in the successful defense of any action,
             suit or proceeding) is asserted by such director, officer or
             controlling person in connection with the shares of common stock
             being registered, the registrant will, unless in the opinion of
             its counsel the matter has been settled by controlling precedent,
             submit to a court of appropriate jurisdiction the question whether
             such indemnification by it is against public policy as expressed
             in the Securities Act and will be governed by the final
             adjudication of such issue.

         (6) For determining any liability under the Securities Act, to treat
             the information omitted from the form of prospectus filed as part
             of this registration statement in reliance upon Rule 430A and
             contained in the form of prospectus filed by the registrant
             pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities
             Act as part of this registration statement as of the time the
             Commission declared it effective.

         (7) For determining any liability under the Securities Act, to treat
             each post-effective amendment that contains a form of prospectus
             as a new registration statement for the securities offered in the
             registration statement, and that offering of the securities at
             that time as the initial bona fide offering of those securities.

(A)  The Common Shares of the Corporation shall have attached thereto the
following rights, privileges, restrictions and conditions:

1.   DIVIDENDS

1.1  Subject to the prior rights of the holders of the Preference Shares and to
any other shares ranking senior to the Common Shares with respect to priority in
the payment of dividends, the holders of the Common Shares shall be entitled to
receive dividends and the Corporation shall pay dividends thereon, as and when
declared by the board of directors of the Corporation, out of moneys properly
applicable to the payment of dividends, in such amount and in such form as the
board of directors may from time to time determine and all dividends which the
directors may declare on the Common Shares shall be declared and paid in equal
amounts per share on all Common Shares at the time outstanding.

2.   DISSOLUTION

2.1  In the event of the dissolution, liquidation or winding-up of the
Corporation, whether voluntary or involuntary, or any other distribution of
assets of the Corporation among its shareholders for the purpose of winding up
its affairs, subject to the prior rights of the holders of the Preference Shares
and to any other shares ranking senior to the Common Shares with respect to
priority in the distribution of assets upon dissolution, liquidation or

remaining property and assets of the Corporation.

3.   VOTING RIGHTS

3.1  The holders of the Common Shares shall be entitled to receive notice of
and to attend all meetings of the shareholders of the Corporation and shall

(B)  The rights, privileges, restrictions and conditions attaching to the
Preference Shares, as a class, are as follows:

1.   DIRECTORS' AUTHORITY TO ISSUE ONE OR MORE SERIES

1.1  The board of directors of the Corporation may issue the Preference Shares
at any time and from time to time in one or more series. Before the first shares
of a particular series are issued, the board of directors of the Corporation
shall fix the number of shares in such series and shall determine, subject to
the limitations set out in the articles, the designation, rights, privileges,
restrictions and conditions to attach to the shares of such series including,
without limiting the generality of the foregoing, the rate or rates, amount or
method or methods of calculation of preferential dividends, whether cumulative
or noncumulative or partially cumulative, and whether such rate(s), amount or
method(s) of calculation shall be subject to change or adjustment in the future,
the currency or currencies of payment, the date or dates and place or places of
payment thereof and the date or dates from which such preferential dividends
shall accrue, the redemption price and terms and conditions of redemption (if
any), the rights of retraction (if any), and the prices and other terms and
conditions of any rights of retraction and whether any additional rights of
retraction may be vested in such holders in the future, voting rights and
conversion or exchange rights (if any) and any sinking fund, purchase fund or
other provisions attaching thereto. Before the issue of the first shares of a
series, the board of directors of the Corporation shall send to the Director (as
defined in the Ontario Business Corporations Act) articles of amendment in the
prescribed form containing a description of such series including the
designation, rights, privileges, restrictions and conditions determined by the
directors.

2.   RANKING OF PREFERENCE SHARES

2.1  No rights, privileges, restrictions or conditions attaching to a series of
Preference Shares shall confer upon a series a priority in respect of dividends
or return of capital in the event of the liquidation, dissolution or
winding-up of the Corporation over any other series of Preference Shares. The
Preference Shares of each series shall rank on a parity with the Preference
Shares of every other series with respect to priority in the payment of
dividends and the return of capital and the distribution of assets of the
Corporation in the event of the liquidation, dissolution or winding-up of the
Corporation, whether voluntary or involuntary, or any other distribution of the
assets of the Corporation among its shareholders for the purpose of winding up
its affairs.

2.2  The Preference Shares shall be entitled to priority over the Common Shares
and over any other shares of any other class of the Corporation ranking junior
to the Preference Shares with respect to priority in the payment of dividends
and the return of capital and the distribution of assets in the event of the
liquidation, dissolution or winding-up of the
<PAGE>   4
                                      -3-

Corporation, whether voluntary or involuntary, or any other distribution of the
assets of the Corporation among its shareholders for the purpose of winding up
its affairs.

2.3  If any amount of cumulative dividends, whether or not declared, or
declared non-cumulative dividends or amount payable on a return of capital in
the event of the liquidation, dissolution or winding-up of the Corporation in
respect of a series of Preference Shares is not paid in full, the Preference
Shares of all series shall participate rateably in respect of all accumulated
cumulative dividends, whether or not declared, and all declared non-cumulative
dividends in accordance with the sums that would be payable on such shares if
all such dividends were declared and paid in full, and in respect of amounts
payable on return of capital in the event of the liquidation, dissolution or
winding-up of the Corporation in accordance with the sums that would be payable
on such repayment of capital if all sums so payable were paid in full; provided,
however, that in the event of there being insufficient assets to satisfy in full
all such claims as aforesaid, the claims of the holders of the Preference Shares
with respect to amounts payable on return of capital shall first be paid and
satisfied and any assets remaining thereafter shall be applied towards the
payment and satisfaction of claims in respect of dividends.

2.4  The Preference Shares of any series may also be given such other
preferences not inconsistent with the provisions hereof over the Common Shares
and over any other shares ranking junior to the Preference Shares as may be
determined in the case of such series of Preference Shares.

2.5  In the event of the liquidation, dissolution or winding-up of the
Corporation, whether voluntary or involuntary, or any other distribution of the
assets of the Corporation among its shareholders for the purpose of winding up
its affairs, the holders of each series of Preference Shares shall, before any
amount shall be paid to or any property or assets of the Corporation distributed
among the holders of the Common Shares or any other shares of the Corporation
ranking junior to the Preference Shares, be entitled to receive (i) an amount
equal to the stated capital attributed to each series of Preference Shares,
respectively, together with, in the case of a series of Preference Shares
entitled to cumulative dividends thereon, all unpaid accumulated cumulative
dividends, whether or not declared (which for such purpose shall be calculated
as if such cumulative dividends were accruing from day to day for the period
from the expiration of the last period for which such cumulative dividends were
paid up to but excluding the date of distribution) and, in the case of a series
of Preference Shares entitled to non-cumulative dividends, all declared and
unpaid non-cumulative dividends thereon, and (ii) if such liquidation,
dissolution, winding-up or distribution shall be voluntary, an additional
amount, if any, equal to any premium which would have been payable on the
redemption of any series of Preference Shares had they been called for
redemption by the Corporation effective the date of distribution and, if any
series of Preference Shares could not be redeemed on such date,
<PAGE>   5
                                      -4-

then an additional amount equal to the greatest premium, if any, which would
have been payable on the redemption of any other series of Preference Shares.

3.       RESTRICTIONS ON DIVIDENDS AND REDEMPTIONS, ETC.

3.1      Except with the approval of all the holders of the Preference Shares,
no dividends shall at any time be declared or paid or set apart for payment on
the Common Shares or any other shares of the Corporation ranking junior to the
Preference Shares unless all dividends up to and including the dividend payable
for the last completed period for which such dividends shall be payable on each
series of Preference Shares then issued and outstanding shall have been
declared and paid or set apart for payment at the date of such declaration or
payment or setting apart for payment on the Common Shares or such other shares
of the Corporation ranking junior to the Preference Shares; nor shall the
Corporation call for redemption, redeem, purchase for cancellation, acquire for
value or reduce or otherwise pay off any of the Preference Shares (less than
the total amount then outstanding) or any Common Shares or any other shares of
the Corporation ranking junior to the Preference Shares unless and until all
dividends up to and including the dividends payable for the last completed
period for which such dividends shall be payable on each series of Preference
Shares then issued and outstanding shall have been declared and paid or set
apart for payment at the date of such call for redemption, purchase,
acquisition, reduction or other payment.

4.       VOTING RIGHTS

4.1      Except as hereinafter referred to or as otherwise provided by law or
in accordance with any voting rights which may from time to time be attached to
any series of Preference Shares, the holders of the Preference Shares as a
class shall not be entitled as such to receive notice of, to attend or to vote
at any meeting of the shareholders of the Corporation.

5.       SPECIFIC MATTERS REQUIRING APPROVAL

5.1      The approval of the holders of the Preference Shares, given in the
manner described in section 6.1 below, shall be required for the creation of
any new shares ranking prior to or on a parity with the Preference Shares, and
if, but only so long as, any cumulative dividends are in arrears or any
declared non-cumulative dividends are unpaid on any outstanding series of
Preference Shares, for the issuance of any additional series of Preference
Shares or of any shares ranking prior to or on a parity with the Preference
Shares.

5.2      The provisions of clauses 1.1 to 6.1 inclusive may be deleted,
amended, modified or varied in whole or in part by a certificate of amendment
issued by the Director appointed
<PAGE>   6

under the Ontario Business Corporations Act, but only with the prior approval of
the holders of the Preference Shares given as hereinafter specified in addition
to any other approval required by the Ontario Business Corporations Act or any
other statutory provisions of like or similar affect, from time to time in
force.

6.   APPROVAL OF THE HOLDERS OF THE PREFERENCE SHARES

6.1  The approval of the holders of the Preference Shares with respect to any
and all matters hereinbefore referred to may be given by at least two thirds
of the votes cast at a meeting of the holders of the Preference Shares duly
called for that purpose and held upon at least 21 days' notice at which the
holders of a majority of the outstanding Preference Shares are present or
represented by proxy. If at any such meeting the holders of a majority of the
outstanding Preference Shares are not present or represented by proxy within
one half-hour after the time appointed for such meeting, then the meeting shall
be adjourned to such date being not less than 30 days later and to such time and
place as may be appointed by the chairman and not less than 21 days' notice

of the Preference Shares present or represented by proxy may transact the
business for which the meeting was originally called and a resolution passed
thereat by not less than two-thirds of the votes cast at such adjourned meeting
shall constitute the approval of the holders of the Preference Shares referred
to above. The formalities to be observed with respect to the giving of notice
of any such meeting or adjourned meeting and the conduct thereof shall be those
from time to time prescribed by the Ontario Business Corporations Act and the
by-laws of the Corporation with respect to meetings of shareholders. On every
poll taken at every such meeting or adjourned meeting every holder of

                      COTTON VALLEY RESOURCES CORPORATION
                 7% CONVERTIBLE DEBENTURE DUE DECEMBER 31, 2001

         THIS DEBENTURE is one of a series of duly authorized issued debentures
of Cotton Valley Resources Corporation, a corporation organized under the laws
of Ontario, Canada and having a principal place of business at 8350 N. Central
Expressway, Suite M2030, Dallas, Texas 75206 (the "Company"), designated as its
7% Convertible Debentures, due December 31, 2001 (the "Debentures"), in an
aggregate principal amount of $4,320,000.

         FOR VALUE RECEIVED, the Company promises to pay to ___________, or
registered assigns (the "Holder"), the principal sum of _________($______), on
or prior to December 31, 2001 or such earlier date as the Debentures are
required to be repaid as provided hereunder (the "Maturity Date") and to pay
interest to the Holder on the principal sum at the rate of 7% per annum, payable
annually on December 31 of each year, commencing December 31, 1997, and on each
Conversion Date (as defined in Section 4(a)(i) of this Debenture). Interest
shall accrue daily commencing on the Original Issue Date (as defined in Section
6 of this Debenture) until payment in full of the principal sum, together with
all accrued and unpaid interest and other amounts which may become due
hereunder, has been made. Interest shall be calculated on the basis of a 360-day
year and for the actual number of days elapsed. Interest hereunder will be paid
to the Person (as defined in Section 6 of this Debenture) in whose name this
Debenture is registered on the records of the Company regarding registration and
transfers of the Debentures (the "Debenture Register"). All overdue, accrued
<PAGE>   2
and unpaid interest and other amounts due hereunder shall bear interest at the
rate of 18% per annum and accrue daily from the date such interest is due
hereunder through and including the date of payment. The principal of, and
interest on, this Debenture are payable in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts, at the address of the Holder last appearing on the
Debenture Register, except that interest due on the principal amount (but not
overdue interest) may, at the Company's option, be paid in shares of Common
Stock (as defined in Section 6 of this Debenture) valued at the Conversion Price
(as defined below) at the time such interest becomes due. All amounts due
hereunder other than interest shall be paid in cash.  Notwithstanding anything
to the contrary contained herein, the Company may not issue shares of the Common
Stock in payment of interest on the principal amount if: (i) the number of
shares of Common Stock at the time authorized, unissued and unreserved for all
purposes, or held as treasury stock, is insufficient to pay interest hereunder
in shares of Common Stock; (ii) such shares are not either registered for resale
pursuant to an Underlying Securities Registration Statement (as defined in
Section 6 of this Debenture) or freely transferable without volume restrictions
pursuant to Rule 144(k) promulgated under the Securities Act of 1933, as amended
(the "Securities Act"), as determined by counsel to the Company pursuant to a
written opinion letter, addressed to and in form and substance acceptable to the
Company's transfer agent or other person or entity performing similar functions
thereto; (iii) such shares are not listed on the American Stock Exchange
("AMEX") (or the Toronto Stock Exchange, Nasdaq National Market, Nasdaq SmallCap
Market, New York Stock Exchange or OTC Bulletin Board) and any other exchange,
market and trading facility on which the Common Stock is then listed for
trading; or (iv) the issuance of such shares would result in the recipient
thereof beneficially owning more than 4.999% of the issued and outstanding
shares of Common Stock as determined in accordance with Rule 13d-3 under the
Securities Exchange Act of 1934, as amended. Payment of interest on the
principal amount in shares of Common Stock is further subject to the provisions
of Section 4(a)(ii) of this Debenture.

         This Debenture is subject to the following additional provisions:

                 Section 1.     This Debenture is exchangeable for an equal
aggregate principal amount of Debentures of different authorized denominations,
as requested by the Holder surrendering the same but shall not be issuable in
denominations of less than integral multiplies of Fifty Thousand Dollars
($50,000) unless such amount represents the full principal balance of Debentures
outstanding to such Holder. No service charge will be made for such registration
of transfer or exchange.

                 Section 2.     This Debenture has been issued subject to
certain investment representations of the original Holder set forth in the
Purchase Agreement and may be transferred or exchanged only in compliance with
the Purchase Agreement. Prior to due presentment to the Company for transfer of
this Debenture, the Company and any agent of the Company may treat the person in
whose name this Debenture is duly registered on the Debenture Register as the
owner hereof for the purpose of receiving payment as herein provided and for all
other purposes, whether or not this Debenture is overdue, and neither the
Company nor any such agent shall be affected by notice to the contrary

         Conversion Date, the Maturity Date, by acceleration or otherwise);

                 (ii)     failure to deliver conversion shares within three

         the date on which written notice of such failure or breach shall have
         been given;

                 (iv)     the Company or any of its subsidiaries shall commence
         a case under any applicable bankruptcy or insolvency laws as now or
         hereafter in effect or any successor thereto, or the Company commences
         any other proceeding under any reorganization, arrangement, adjustment

         relating to the Company or any subsidiary thereof; or there is

         for a period of 60 days; or the Company or any subsidiary thereof is
         adjudicated insolvent or bankruptcy; or any order of relief or other
         order approving any such case or proceeding is entered; or the Company
         or any subsidiary thereof suffers any appointment of any custodian or
         the like for it or any substantial part of its property which continues
         undischarged or unstayed for a period of 60 days; or the Company or any
         subsidiary thereof makes a general assignment for the benefit of
         creditors; or the Company shall fail to pay, or shall state that it is
         unable to pay, or shall be unable to pay, its debts generally as they
         become due; or the Company or any subsidiary thereof shall call a
         meeting of its creditors with a view to arranging a composition or

         effective any of the foregoing;

                 (v)      the Company shall default in any of its obligations
         or an event shall occur, or shall fail to occur, which gives (or would
         give after the passage of time or giving of notice or both) the
         payee of any such obligation the right to accelerate the payment



                                      -3-
<PAGE>   4
         thereof under any mortgage, credit agreement or other facility,
         indenture agreement, promissory note or other instrument under which
         there may be issued, or by which there may be secured or evidenced any
         indebtedness of the Company in an amount exceeding one hundred
         thousand dollars ($100,000), whether such indebtedness now exists or
         shall hereafter be created and such default shall result in such
         indebtedness becoming or being declared due and payable prior to the
         date on which it would otherwise become due and payable;

                 (vi)     the Common Stock shall be delisted from the AMEX or
         any other national securities exchange or market on which such Common
         Stock is then listed for trading or suspended from trading thereon
         without being relisted or having such suspension lifted, as the case
         may be, within three (3) Trading Days (if after the Original Issue
         Date the Common Stock shall be listed for trading or quoted on the
         Toronto Stock Exchange, Nasdaq SmallCap Market, Nasdaq National Market
         or any other national securities exchange or market, this provision
         shall apply to any delistings or suspensions therefrom);

                 (vii)    the Company shall be a party to any merger or
         consolidation pursuant to which the Company shall not be the surviving
         entity or shall sell, transfer or otherwise dispose of all or
         substantially all of its assets in one or more transactions, or shall
         redeem more than a de minimis number of shares of Common Stock (other
         than redemptions of Underlying Shares);

                 (viii)   an Underlying Securities Registration Statement shall
         not have been declared effective by the Securities and Exchange
         Commission (the "Commission") on or prior to the 150th day after the
         Original Issue Date; or

                 (ix)     an Event (as hereinafter defined) shall not have been
         cured prior to the expiration of thirty (30) days from the Event Date
         (as hereinafter defined) relating thereto (other than an Event
         resulting from a failure of an Underlying Securities Registration
         Statement to be declared effective by the Commission on or prior to
         the 150th day after the Original Issue Date).

                 (b)      If any Event of Default occurs and is continuing, the
Holder may, by written notice to the Company, declare the full principal amount
of this Debenture (and, at such Holder's option, all other Debentures then held
by such Holder), together with interest and other amounts owing in respect
thereof, to the date of acceleration, to be, whereupon the same shall become,
immediately due and payable in cash. The aggregate amount payable in respect of
the Debentures shall be equal to the sum of (i) the Mandatory Repayment Amount
(as defined in Section 6 of this Debenture) plus (ii) the product of (A) the
number of Underlying Shares issued in respect of conversions hereunder and then
held by the demanding Holder and (B) the Per Share Market Value on the date
prepayment is demanded or the date the full prepayment price is paid, whichever
is greater. The demanding Holder need not provide and the Company hereby waives
any presentment, demand, protest or other notice of any kind, and the Holder
may immediately and without expiration of any grace period enforce any and all
of its rights and remedies hereunder and all other remedies available to it
under applicable law. Such declaration


                                      -4-
<PAGE>   5
may be rescinded and annulled by Holder at any time prior to payment hereunder.
No such rescission or annulment shall affect any subsequent Event of Default or
impair any right consequent thereon.

         Section 4.

         (a)(i)  This Debenture shall be convertible into shares of Common
Stock at the option of the Holder in whole or in part at any time and from time
to time after the original Issue Date and prior to the close of business on the
Maturity Date. The number of shares of Common Stock as shall be issuable upon a
conversion hereunder shall be determined by dividing the outstanding principal
amount of this Debenture to be converted, plus all accrued but unpaid interest
thereon (which the Company does not elect to pay in cash), by the Conversion
Price (as defined below), each as subject to adjustment as provided hereunder.
The Holder shall effect conversions by surrendering the Debentures (or such
portions thereof) to be converted, together with the form of conversion notice
attached hereto as Exhibit A (the "Conversion Notice") to the Company. Each
Conversion Notice shall specify the principal amount of Debentures to be
converted and the date on which such conversion is to be effected, which date
may not be prior to the date such Conversion Notice is deemed to have been
delivered hereunder (the "Conversion Date"). If no Conversion Date is specified
in a Conversion Notice, the Conversion Date shall be the date that the
Conversion Notice is deemed delivered hereunder.  Subject to Sections 4(a)(ii)
and 4(b) of this Debenture and Section 3.8 of the Purchase Agreement, each
Conversion Notice, once given, shall be irrevocable. If the Holder is
converting less than all of the principal amount represented by the
Debenture(s) tendered by the Holder with the Conversion Notice, or if a
conversion hereunder cannot be effected in full for any reason, the Company
shall honor such conversion to the extent permissible hereunder and shall
promptly deliver to such Holder (in the manner and within the time set forth in
Section 5(b) of this Debenture) a new Debenture for such principal amount as
has not been converted.

                 (ii)     Certain Regulatory Approval. If on any Conversion
Date (A) the Common Stock is listed for trading on the Nasdaq National Market,
Nasdaq SmallCap Market, New York Stock Exchange or AMEX, (B) the Conversion
Price then in effect is such that the aggregate number of shares of the Common
Stock that would then be issuable upon conversion of the entire outstanding
principal amount of Debentures, together with any shares of the Common Stock
previously issued upon conversion of Debentures and as payment of interest
thereunder would equal or exceed 20% of the number of shares of the Common
Stock outstanding on the Original Issue Date (such number of shares as would
not equal or exceed such 20% limit, the "Issuable Maximum"), and (C) the
Company has not previously obtained the vote of shareholders, if any, as may be
required by the rules and regulations of The Nasdaq Stock Market, the New York
Stock Exchange, the AMEX or any other securities market or exchange on which
the Common Stock is then listed or quoted for trading (as applicable) to
approve the issuance of Common Stock in excess of the Issuable Maximum in a
private placement for less than the greater of book or fair market value of the
Common Stock, then the Company shall issue to any Holder so requesting
conversion of Debentures its pro rata portion of the Issuable Maximum in the
same ratio that the aggregate principal amount of Debentures then outstanding
and held by such Holder bears to the aggregate principal amount of Debentures
then outstanding and, with respect to the remainder of the aggregate principal
amount of Debentures then held


                                      -5-
<PAGE>   6
by such Holder for which a conversion in accordance with the Conversion Price
would result in an issuance of Common Stock in excess of such Holder's pro rata
portion of the Issuable Maximum, the Holder shall have the option to require
the Company to either (1) prepay the balance of the aggregate principal amount
of the Debentures then outstanding and held by such Holder at a price equal to
the sum of the Mandatory Prepayment Amount or (2) issue and deliver to such
Holder (i) a number of shares of Common Stock as equals (x) the principal
amount of Debentures (or such portions thereof) tendered for conversion in
respect of the Conversion Notice at issue but for which a conversion in
accordance with the other terms hereof would result in an issuance of Common
Stock in excess of such Holder's pro rata portion of the Issuable Maximum
divided by (y) the Average Price on the Closing Date, and (ii) cash in an
amount equal to the difference between (A) the product of (x) the Per Share
Market Value on the Conversion Date and (y) the number of shares of Common
Stock in excess of such Holder's pro rata portion of the Issuable Maximum that
would have otherwise been issuable to the Holder in respect of such conversion
but for the provisions of this Section and (B) the value of the shares of
Common Stock issued under Section 4(a)(ii)(2)(i) above (such amount of cash
being hereinafter referred to as the "Discount Equivalent"). In the event of
any failure by the Company to pay the full Discount Equivalent or prepayment
price for the Debentures, as the case may be, pursuant to this Section 4(a)(ii)
within seven days after the date payable, the Company will pay interest thereon
at a rate of 18% per annum, which will accrue daily, to the converting Holder,
accruing from the Conversion Date until such amount, plus all such interest
thereon, is paid in full.  Any failure to pay the prepayment price or Discount
Equivalent under this Section 4(a)(ii) prior to the date that interest thereon
commences shall constitute a default under Section 3(a)(i). The entire
prepayment price or Discount Equivalent, as the case may be, including interest
thereon, shall be paid in cash.

         (b)     Not later than three Trading Days after the Conversion Date,
the Company will deliver to the Holder (i) a certificate or certificates which
shall be free of restrictive legends and trading restrictions (other than those
required by Section 3.1(b) of the Purchase Agreement) representing the number
of shares of the Common Stock being acquired upon the conversion of Debentures
(subject to reduction pursuant to Section 4(a)(ii) hereof and Section 3.8 of
the Purchase Agreement), (ii) Debentures in a principal amount equal to the
principal amount of Debentures not converted; (iii) a bank check in the amount
of all accrued and unpaid interest (if the Company has elected to pay accrued
interest in cash), together with all other amounts then due and payable in
accordance with the terms hereof, in respect of Debentures tendered for
conversion, (iv) if the Company has elected to pay accrued interest in shares
of the Common Stock, certificates, which shall be free of restrictive legends
and trading restrictions (other than those required by Section 3.1(b) of the
Purchase Agreement), representing such number of shares of the Common Stock as
equals such interest divided by the Conversion Price calculated on the
Conversion Date, and (v) if the Conversion Price used in such Conversion is
the Ceiling Price (as defined in (c) below), Warrants that will (A) expire on
December 31, 2001, (B) have an exercise price equal to the Average Price on the
Closing Date, (C) be exercisable into an amount of shares of Common Stock equal
to the product of (a) the face value of the Debentures converted divided by the
Conversion Price used in connection with such conversion and (b) 25%, and (D)
be subject to the terms set forth in the Warrants; provided, however, that the
Company shall not be obligated to issue certificates evidencing the shares of
the Common Stock or the Warrants, if any, issuable upon conversion of the
principal amount of Debentures until


                                      -6-
<PAGE>   7
Debentures are delivered for conversion to the Company or the Holder notifies
the Company that such Debenture has been mutilated, lost, stolen or destroyed
and complies with Section 9 hereof. The Company shall, upon request of the
Holder, use its best efforts to deliver any certificate or certificates
required to be delivered by the Company under this Section electronically
through the Depository Trust Corporation or another established clearing
corporation performing similar functions. If in the case of any Conversion
Notice such certificate or certificates, including for purposes hereof, any
shares of the Common Stock to be issued on the Conversion Date on account of
accrued but unpaid interest hereunder, are not delivered to or as directed by
the applicable Holder by the third Trading Day after the Conversion Date, the
Holder shall be entitled by written notice to the Company at any time on or
before its receipt of such certificate or certificates thereafter, to rescind
such conversion, in which event the Company shall immediately return the
Debentures tendered for conversion.

         (c)      (i)     The conversion price (the "Conversion Price") in
effect on any Conversion Date shall be the lesser of (A) 90% of the average of
the three lowest closing bid prices of the Common Stock in the ten Trading Day
period prior to the date of submission of a Conversion Notice and (B) 120% of
the Average Price on the Closing Date (the "Ceiling Price") provided that within
each successive 30-day period following the Closing Date, a Holder may not
convert Debentures having a face value greater than 10% of the aggregate face
value of all Debentures held by such Holder on the Closing Date at a Conversion
Price below the Floor Price (as defined in Section 6 of this Debenture),
provided, that if a Holder has converted Debentures up to such 10% limit in such
30-day period and the then Conversion Price is below the Floor Price such Holder
may continue to convert its Debentures for the balance of such period using a
Conversion Price equal to the Floor Price. Notwithstanding anything herein to
the contrary, (a) if an Underlying Securities Registration Statement is not
filed on or prior to the Filing Date (as such term is defined in the
Registration Rights Agreement), or (b) if the Company fails to file with the
Commission a request for acceleration in accordance with Rule 12d1-2 promulgated
under the Securities Exchange Act of 1934, as amended, within five (5) days of
the date that the Company is notified (orally or in writing, whichever is
earlier) by the Commission that an Underlying Securities Registration Statement
will not be "reviewed" or is not subject to further review or comment by the
Commission, or (c) if the Underlying Securities Registration Statement is not
filed with the Commission on or prior to the Filing Date (as such term is
defined in the Registration Rights Agreement) or declared effective by the
Commission on or prior to the Effective Date (as such term is defined in the
Registration Rights Agreement), or (d) if such Underlying Securities
Registration Statement is filed with and declared effective by the Commission
but thereafter ceases to be effective as to all Registrable Securities (as such
term is defined in the Registration Rights Agreement) at any time prior to the
expiration of the "Effectiveness Period" (as such term is defined in the
Registration Rights Agreement), without being succeeded by a subsequent
Underlying Securities Registration Statement filed with and declared effective
by the Commission within ten (10) days, or (e) if trading in the Common Stock
shall be suspended, or if the Common Stock shall be delisted from trading, on
the AMEX or any other national securities market or exchange on which the Common
Stock is then listed or quoted for trading for any reason for more than three
(3) Trading Days, or (f) if the conversion rights of the Holders of Debentures
are suspended for any reason or if the Holder is not permitted to resell
Registrable Securities under the Underlying Securities Registration Statement
(any such failure being referred to as an "Event," and for purposes of clauses
(a), (c)


                                      -7-
<PAGE>   8
and (f) the date on which such Event occurs, or for purposes of clause (b) the
date on which such five (5) days period is exceeded, or for purposes of clause
(d) the date which such ten (10) day period is exceeded, or for purposes of
clause (e) the date on which such three (3) Trading Day period is exceeded,
being referred to as "Event Date"), then on the Business Day following an Event
Date the Company shall pay to the holders of the Debentures 1% of the aggregate
principal amount of Debentures then outstanding (each holder being entitled to
receive such portion of such amount as equals its pro rata portion of the
Debentures then outstanding) in cash as liquidated damages, and not as a
penalty, and the Company shall pay to the holders of the Debentures an
additional 1% of the aggregate principal amount of Debentures then outstanding
(each holder being entitled to receive such portion of such amount as equals
its pro rata portion of the Debentures then outstanding) in cash as liquidated
damages, and not as a penalty, on the first day of each monthly anniversary of
such Event Date until such time as the applicable Event is cured. The
provisions of this Section are not exclusive and shall in no way limit the
Company's obligations under the Registration Rights Agreement.

                 (ii)     If the Company, at any time while any Debentures are
outstanding, (a) shall pay a stock dividend or otherwise make a distribution or
distributions on shares of its Common Stock or any other equity or equity
equivalent securities payable in shares of the Common Stock, (b) subdivide
outstanding shares of the Common Stock into a larger number of shares, (c)
combine outstanding shares of the Common Stock into a smaller number of shares,
or (d) issue by reclassification of shares of the Common Stock any shares of
capital stock of the Company, the Ceiling Price shall be multiplied by a
fraction of which the numerator shall be the number of shares of the Common
Stock (excluding treasury shares, if any) outstanding before such event and of 
which the denominator shall be the number of shares of the Common Stock
outstanding after such event. Any adjustment made pursuant to this Section shall
become effective immediately after the record date for the determination of
stockholders entitled to receive such dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision,
combination or re-classification.

                 (iii)    If the Company, at any time while any Debentures are
outstanding, shall issue rights or warrants to all holders of the Common Stock
(and not to Holders of Debentures) entitling them to subscribe for or purchase
shares of the Common Stock at a price per share less than the Per Share Market
Value of the Common Stock at the record date mentioned below, the Ceiling Price
shall be multiplied by a fraction, of which the denominator shall be the number
of shares of the Common Stock (excluding treasury shares, if any) outstanding
on the date of issuance of such rights or warrants plus the number of
additional shares of the Common Stock offered for subscription or purchase, and
of which the numerator shall be the number of shares of the Common Stock
(excluding treasury shares, if any) outstanding on the date of issuance of such
rights or warrants plus the number of shares which the aggregate offering price
of the total number of shares so offered would purchase at such Per Share
Market Value. Such adjustment shall be made whenever such rights or warrants
are issued, and shall become effective immediately after the record date for
the determination of stockholders entitled to receive such rights or warrants.
However, upon the expiration of any right or warrant to purchase shares of the
Common Stock the issuance of which resulted in an adjustment in the Ceiling
Price pursuant to this Section, if any such right or warrant shall expire and
shall not have been exercised, the Ceiling Price shall immediately upon such
expiration be


                                      -8-
<PAGE>   9
recomputed and effective immediately upon such expiration be increased to the
price which it would have been (but reflecting any other adjustments in the
Ceiling Price made pursuant to the provisions of this Section 4 after the
issuance of such rights or warrants) had the adjustment of the Ceiling Price
made upon the issuance of such rights or warrants been made on the basis of
offering for subscription or purchase only that number of shares of the Common
Stock actually purchased upon the exercise of such rights or warrants actually
exercised.

                 (iv)     If the Company, at any time while Debentures are
outstanding, shall distribute to all holders of the Common Stock (and not to
Holders of Debentures) evidences of its indebtedness or assets or rights or
warrants to subscribe for or purchase any security, then in each such case the
Ceiling Price at which Debentures shall thereafter be convertible shall be
determined by multiplying the Ceiling Price in effect immediately prior to the
record date fixed for determination of stockholders entitled to receive such
distribution by a fraction of which the denominator shall be the Per Share
Market Value of the Common Stock determined as of the record date mentioned
above, and of which the numerator shall be such Per Share Market Value of the
Common Stock on such record date less the then fair market value at such record
date of the portion of such assets or evidence of indebtedness so distributed
applicable to one outstanding share of the Common Stock as determined by the
Board of Directors in good faith; provided, however, that in the event of a
distribution exceeding ten percent (10%) of the net assets of the Company, such
fair market value shall be determined by a nationally recognized or major
regional investment banking firm or firm of independent certified public
accountants of recognized standing (which may be the firm that regularly
examines the financial statements of the Company) (an "Appraiser") selected in
good faith by the holders of a majority in interest of Debentures then
outstanding; and provided, further, that the Company, after receipt of the
determination by such Appraiser shall have the right to select an additional
Appraiser, in good faith, in which case the fair market value shall be equal to
the average of the determinations by each such Appraiser. In either case the
adjustments shall be described in a statement provided to the holders of
Debentures of the portion of assets or evidences of indebtedness so distributed
or such subscription rights applicable to one share of the Common Stock. Such
adjustment shall be made whenever any such distribution is made and shall become
effective immediately after the record date mentioned above.

                 (v)      In case of any reclassification of the Common Stock
or any compulsory share exchange pursuant to which the Common Stock is
converted into other securities, cash or property, the Holder of this Debenture
shall have the right thereafter to, at its option, (A) convert the then
outstanding principal amount, together with all accrued but unpaid interest and
any other amounts then owing hereunder in respect of this Debenture only into
the shares of stock and other securities, cash and property receivable upon or
deemed to be held by holders of the Common Stock following such
reclassification or share exchange, and the Holders of the Debentures shall be
entitled upon such event to receive such amount of securities, cash or property
as the shares of the Common Stock of the Company into which the then
outstanding principal amount, together with all accrued but unpaid interest and
any other amounts then owing hereunder in respect of this Debenture could have
been converted immediately prior to such reclassification or share exchange
would have been entitled or (B) require the Company to prepay, from funds
legally available therefor at the time of such prepayment, the aggregate of its
outstanding principal amount of Debentures, plus all interest


                                      -9-
<PAGE>   10
and other amounts due and payable thereon, at a price determined in accordance
with Section 3(b). The entire prepayment price shall be paid in cash. This
provision shall similarly apply to successive reclassifications or share
exchanges.

                 (vi)     All calculations under this Section 4 shall be made
to the nearest cent or the nearest 1/100th of a share, as the case may be.

                 (vii)    Whenever the Ceiling Price is adjusted pursuant to
any of Section 4(c)(ii) - (v), the Company shall promptly mail to each Holder
of Debentures a notice setting forth the Ceiling Price after such adjustment
and setting forth a brief statement of the facts requiring such adjustment.

                 (viii)  If:

                          A.      the Company shall declare a dividend (or any
                                  other distribution) on its Common Stock; or

                          B.      the Company shall declare a special
                                  nonrecurring cash dividend on or a redemption
                                  of its Common Stock; or

                          C.      the Company shall authorize the granting to
                                  all holders of the Common Stock rights or
                                  warrants to subscribe for or purchase any
                                  shares of capital stock of any class or of
                                  any rights; or

                          D.      the approval of any stockholders of the
                                  Company shall be required in connection with
                                  any reclassification of the Common Stock of
                                  the Company, any consolidation or merger to
                                  which the Company is a party, any sale or
                                  transfer of all or substantially all of the
                                  assets of the Company, of any compulsory
                                  share of exchange whereby the Common Stock is
                                  converted into other securities, cash or
                                  property; or

                          E.      the Company shall authorize the voluntary or
                                  involuntary dissolution, liquidation or
                                  winding up of the affairs of the Company;

then the Company shall cause to be filed at each office or agency maintained
for the purpose of conversion of the Debentures, and shall cause to be mailed
to the Holders of Debentures at their last addresses as they shall appear upon
the stock books of the Company, at least 30 calendar days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be
taken, the date as of which the holders of the Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,


                                      -10-
<PAGE>   11
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange; provided, however,
that the failure to mail such notice or any defect therein or in the mailing
thereof shall not affect the validity of the corporate action required to be
specified in such notice. Holders are entitled to convert Debentures, without
restriction under Section 4(c)(i) of this Debenture, during the 30-day period
commencing the date of such notice to the effective date of the event
triggering such notice.

         (d)     The Company covenants that it will at all times reserve and
keep available out of its authorized and unissued shares of the Common Stock
solely for the purpose of issuance upon conversion of the Debentures and
payment of interest on the Debentures, each as herein provided, free from
preemptive rights or any other actual contingent purchase rights of persons
other than the Holders, not less than such number of shares of the Common Stock
as shall be required by the Purchase Agreement (taking into account the
adjustments and restrictions of Section 4(c) of this Debenture).

         (e)     Upon a conversion hereunder, the Company shall not be required
to issue stock certificates representing fractions of shares of the Common
Stock, but may if otherwise permitted, make a cash payment in respect of any
final fraction of a share based on the Per Share Market Value at such time. If
the Company elects not, or is unable, to make such a cash payment, the holder
shall be entitled to receive, in lieu of the final fraction of a share, one
whole share of Common Stock.

         (f)     The issuance of certificates for shares of the Common Stock or
Warrants, if any on conversion of the Debentures shall be made without charge
to the Holders thereof for any documentary stamp or similar taxes that may be
payable in respect of the issue or delivery of such certificate, provided that
the Company shall not be required to pay any tax that may be payable in respect
of any transfer involved in the issuance and delivery of any such certificate
upon conversion in a name other than that of the Holder of such Debentures so
converted and the Company shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.

         (g)     Any and all notices or other communications or deliveries to
be provided by the Holders of the Debentures hereunder, including, without
limitation, any Conversion Notice, shall be in writing and delivered
personally, by facsimile, sent by a nationally recognized overnight courier
service or sent by certified or registered mail, postage prepaid, addressed to

by notice to the Holders delivered in accordance with this Section. Any and all
notices or other communications or deliveries to be provided by the Company
hereunder shall be in writing and delivered personally, by facsimile, sent by a
nationally recognized overnight courier service or sent by certified or
registered mail, postage prepaid, addressed to each Holder of the Debentures at
the facsimile

<PAGE>   12
telephone number or address of such Holder appearing on the books of the
Company, or if no such facsimile telephone number or address appears, at the
principal place of business of the holder. Any notice or other communication or
deliveries hereunder shall be deemed given and effective on the earliest of (i)
the date of transmission, if such notice or communication is delivered via
facsimile at the facsimile telephone number specified in this Section prior to
7:00 p.m. (New York City time), (ii) the date after the date of transmission, if
such notice or communication is delivered via facsimile at the facsimile

time) on any date and earlier than 11:59 p.m. (New York City time) on such date,
(iii) four days after deposit in the United States mail, (iv) the Business Day
following the date of mailing, if send by nationally recognized overnight

required to be given. For purposes of Section 4(c)(i), if a Conversion Notice is
delivered by facsimile prior to 7:00 p.m. (New York City time) on any date, then
the day prior to such date shall be the last Trading Day calculated to determine
the Conversion Price applicable to such Conversion Notice, and the date of such
delivery shall commence the counting of days for purposes of Section 4(b).

         Section 5.

         (a)     The Company shall have the right, exercisable at any time upon
twenty (20) Trading Days prior written notice to the Holders of the Debentures
to be prepaid (the "Optional Prepayment Notice"), to prepay, from funds legally
available therefor at the time of such prepayment, all or any portion of the
outstanding principal amount of the Debentures which have not previously been
repaid or for which Conversion Notices have not previously been delivered
hereunder, at a price equal to the Optional Prepayment Price (as defined below).
Any such prepayment by the Company shall be in cash and shall be free of any
claim of subordination. The Holders shall have the right to tender, and the
Company shall honor Conversion Notices, without restriction under Section
4(c)(i) of this Debenture, delivered prior to the expiration of the twentieth
(20th) Trading Day after receipt by the Holders of an Optional Prepayment Notice
for such Debentures (such date, the "Optional Prepayment Date").

         (b)     If any portion of the Optional Prepayment Price shall not be
paid by the Company by the Optional Prepayment Date, the Optional Prepayment
Price shall be increased by 18% per annum (to accrue daily) until paid (which
amount shall be paid as liquidated damages and not as a penalty). In addition,
if any portion of the optional Prepayment Price remains unpaid through the
expiration of the Optional Prepayment Date, the Holder subject to such
prepayment may elect by written notice to the Company to either (i) demand
conversion in accordance with the formula and the time period therefor set forth
in Section 4, without restriction under Section 4(c)(i) of this Debenture, of
any portion of the principal amount of Debentures for which the Optional
Prepayment Price, plus accrued liquidated damages thereof, has not been paid in
full (the "Unpaid Prepayment Principal Amount"), in which event the applicable
Per Share Market Value shall be the lower of the Per Share Market Value
calculated on the Optional Prepayment Date and the Per Share Market Value as of
the Holder's written demand for conversion, or (ii) invalidate ab initio such
optional redemption, notwithstanding anything herein contained to the contrary.
If the Holder elects option (i) above, the Company shall within three (3)
Trading Days after such election is deemed delivered hereunder, issue and
deliver to the Holder the shares of Common Stock issuable upon conversion of the
Unpaid


                                      -12-
<PAGE>   13
Prepayment Principal Amount and otherwise perform its obligations hereunder
with respect thereto; or, if the Holder elects option (ii) above, the Company
shall promptly, and in any event not later than three Trading Days from receipt
of notice of such election, return to the Holder new Debentures for the full
Unpaid Prepayment Principal Amount.

         (c)     The "Optional Prepayment Price" for any Debentures shall equal
the sum of (i) the quotient of (A) the face amount of such Debentures plus all
accrued but unpaid interest and (B) 75%, and (ii) all other amounts and
liquidated damages due in respect of such principal amount.

         (d)     The Company shall also have the option to prepay any or all of
the aggregate amount of Debentures that have been tendered for conversion at a
Conversion Price below the Floor Price in each successive 30-day period
following the Closing Date for an amount of cash equal to the sum of (i) the
quotient of (A) the face amount of the Debentures tendered for conversion at a
Conversion Price below the Floor Price plus all accrued but unpaid interest and
(B) 90% and (ii) all other amounts and liquidated damages due in respect of
such principal amount. In order to exercise such option in any such 30-day
period, the Company must notify the Holders of the Company's election not less
than ten Trading Days prior the commencement of such 30-day period.

         Section 6. For the purposes hereof, the following terms shall have the

         "Mandatory Repayment Amount" for any Debentures shall equal the sum of
(i) the principal amount of Debentures to be prepaid, plus all accrued and
unpaid interest thereon, divided by the Conversion Price on (x) the date the
Mandatory Prepayment Amount is demanded or (y) the date the Mandatory
Prepayment Amount is paid in full, whichever is less, multiplied by the Per
Share Market Value on (x) the date the Mandatory Prepayment Amount is demanded
or (y) the date the Mandatory Prepayment Amount is paid in full, whichever is
greater, and (ii) all other amounts, costs, expenses and liquidated damages due
in respect of such Debentures.

Incorporated (or any similar organization or agency succeeding its functions of
reporting prices), such closing bid price shall be determined by reference to
"Pink Sheet" quotes for the relevant conversion period as determined in good
faith by the Holder or (e) if the Common Stock is not then publicly traded, the
fair market value of a share of Common Stock as determined by an appraiser
selected in good faith by the Holders of a majority in interest of the
Debentures (the Company, after receipt of the determination by such appraiser,
shall have the right to select an additional appraiser, in which case, the fair
market value shall be equal to the average of the determinations by each such
appraiser); provided, however, that all determinations of the Per Share Market

                         REPRESENTATIONS AND WARRANTIES

2.01     Seller represents and warrants to Buyer as follows:

         2.01.01          Organization Standing and Power. Seller is a
         corporation duly organized, validly existing and in good standing
         under the laws of the state of Texas, having all requisite power
         and authority to own, lease and operate its properties and to 
         carry on its business as now being conducted.

         2.01.02          Authority and Enforceability. The execution and
         delivery by Seller of this Agreement, and the consummation of
         the transactions contemplated hereby, have been duly and validly 
         authorized by all necessary corporate action on the part of Seller.
         This Agreement is the valid and binding obligation of Seller, 
         enforceable against Seller in accordance with its terms, limited,
         however, by the effects of bankruptcy, insolvency, reorganization,
         moratorium and similar laws from time to time in effect relating to
         the rights and remedies of creditors, as well as to general principles
         of equity (regardless of whether such enforceability is considered in a
         proceeding in equity or at law). Neither the execution and delivery by
         Seller of this Agreement nor the consummation of the transactions 
         contemplated hereby, nor compliance by Seller with any of the 
         provisions hereof, will 

                 (i)      conflict with or result in a breach of any provision 
                 of Seller's articles of incorporation, or bylaws,


PURCHASE AND SALE AGREEMENT, PAGE 5
<PAGE>   6

                  (ii)     except with respect to third-party consents,
                  releases or waivers required in connection with agreements and
                  properties to be assigned pursuant to this Agreement (it being
                  understood that Seller will attempt to obtain such required
                  consents, releases or waivers) result in a material default
                  (with due notice or lapse or time or both) or give rise to any
                  right of termination, cancellation or acceleration under any
                  of the terms, conditions or provisions of any note, bond,
                  mortgage, indenture, license or agreement to which Seller is a
                  party or by which Seller or any of Seller's properties or
                  assets may be bound or,

                  (iii)    violate any order, writ, injunction, judgment,
                  decree, statute, rule or regulation applicable to Seller, or
                  Seller's properties or assets, assuming receipt of all routine
                  governmental consents normally acquired after the consummation
                  of transactions such as transactions of the nature
                  contemplated by this Agreement.

         2.01.03          Suits and Litigation. Except as disclosed on Schedule
         2.01.03, there are no actions, suits, claims, proceedings, agency 
         enforcement actions or investigations pending or, to the best knowledge
         of Seller, threatened against or affecting the Subject Properties, or
         against Seller which has affected or could affect Seller's ability to
         consummate the transactions contemplated by this Agreement.

         2.01.04          Liability for Brokers' Fees. Buyer will not
         directly or indirectly incur any liability or expense as a result of
         any undertakings or agreements of Seller for brokerage fees, finder's
         fees, agent's commissions or other similar forms of compensation in
         connection with this Agreement or any agreement or transaction
         contemplated hereby.

         2.01.05          Royalties. During the period of Seller's ownership
         of the Subject Properties, all royalties, overriding royalties,
         compensatory royalties and other payments due from or in respect of
         production with respect to the Subject Properties for the period prior
         to the Closing Date have been or will be properly and correctly paid or
         provided for. Seller has not received any unresolved written notice
         from any lessor of the Leases which demands compensation or
         reimbursement or release as a result of any alleged mispayment by
         Seller of any royalties due with respect to the Leases.

         2.01.06          Payments. All payments required to be made by
         Seller to third parties for labor performed, materials furnished or
         other services rendered on the Subject Properties during the ownership
         thereof by Seller have been or will be properly and timely paid or
         provided for.

         2.01.07          No Demands. Seller has received no actual notice of
         any claimed defaults, offsets or cancellations from any lessors with
         respect to the Leases, and Seller has no actual knowledge of the
         existence of any material default existing with respect to any of the
         Leases.

PURCHASE AND SALE AGREEMENT, PAGE 6
<PAGE>   7

         2.01.08          Taxes. All ad valorem, real property, personal
         property, production, severance, excise and other taxes applicable
         to Seller's ownership and operation of the Subject Properties prior to
         the Closing Date and that have become due and payable have been or
         will be duly and timely paid.

         2.01.09          Governmental Rules. To the best of Seller's
         knowledge, Seller is not in default under or in violation of any
         law, order, writ, injunction, rule, regulation or degree of any
         governmental body, agency or court or of any commission or other
         administrative agency, except to the extent of any noncompliance that
         is not reasonably expected to result in an adverse effect on the
         Subject Properties, taken as a whole.

         2.01.10          Environmental Matters. NOTWITHSTANDING ANYTHING
         CONTAINED IN THIS AGREEMENT TO THE CONTRARY, IT IS SPECIFICALLY
         UNDERSTOOD THAT SELLER HAS NOT MADE AND DOES NOT MAKE ANY
         REPRESENTATIONS, EXPRESS OR IMPLIED, WITH RESPECT TO THE
         ENVIRONMENTAL CONDITION OF THE SUBJECT PROPERTIES OR COMPLIANCE
         WITH ENVIRONMENTAL LAWS AND THAT BUYER HAS NOT RELIED UPON THE
         ACCURACY OR COMPLETENESS OF ANY STATEMENTS, SAMPLES, MATERIALS, TEST

the Effective Date (the "Assumed Obligations") including, but without
limitation, the following: (A) the obligation to (i) plug and abandon or remove
and dispose of all wells, platforms, structures, flow lines, pipelines, and the
other equipment now or hereafter located on the Leases, (ii) cap and bury all

removal, disposal, and restoration operations shall be in compliance with
applicable laws and regulations and contracts, and shall be conducted in a
good and workmanlike manner.

7.03     Indemnification by Buyer. Buyer shall assume all liability for and
indemnify Seller, its directors, officers, employees and representatives,
against all losses, costs, expenses, claims and causes of action ("Claims"),

(ii) arising under the Assumed Obligations, or (iii) otherwise arising in
connection with or relating to the Subject Properties for all time periods prior

7.04     NORM. It is expressly recognized that the land or water bottoms covered
by the Leases listed in Exhibit A with surface facilities and production
equipment located thereon, having been used in connection with oil and gas
production activities, may contain naturally occurring radioactive materials
("NORM") as a result of these operations. Accordingly, lands, water bottoms,
surface facilities, and production equipment transferred herein are transferred
with the restriction that they will be used only in connection with oil and gas
producing activities associated with these properties, and will not be
subsequently transferred for unrestricted use unless and until the
concentrations of NORM associated therewith are below the levels specified as
allowable for unrestricted transfer as set forth in any regulations, and
subsequent amendments thereto. Additionally, Buyer agrees to comply with all
laws and regulations applicable to said water bottoms, surface facilities, and
production equipment relating to NORM and to indemnify and hold harmless Seller
from and against any and all liability, cost or expense arising from the
existence or rededication of NORM.

7.05     Indemnification Procedures.

         7.05.01          Within ten (10) business days after Seller or Buyer
         becomes aware of facts giving rise to a Claim by it for indemnification
         pursuant to this Article VII, and prior to the expenditure or approval
         of the expenditure of any funds, Seller or Buyer will provide notice
         thereof in writing to the other party (a "Claim Notice") specifying the
         nature and specific basis for such Claim and a copy of all papers
         served with respect to such Claim (if any). For purpose of this
         Section, receipt of written notice of any demand, assertion, claim,
         action or proceeding (judicial, administrative or otherwise) by or from
         any person or entity other than a party to this Agreement or any
         affiliate thereof which gives rise to a Claim on behalf of such party
         shall constitute the discovery of facts giving rise to a Claim by it
         and shall require prompt notice of the receipt of such matter as
         provided in the first sentence of this Section. Each Claim Notice shall
         set forth a reasonable description of the Claim as the party claiming
         indemnification shall then have and shall contain a statement to the
         effect that the party is making a Claim pursuant to and formal demand
         for indemnification under, this Article VII. The Claim Notice must set
         forth the particular provision in this Article VII and any related
         provision in this Agreement pursuant to which such indemnification
         Claim is made.

         7.05.02          The indemnifications provided by this Agreement are
         expressly subject to the following:

PURCHASE AND SALE AGREEMENT, PAGE 15
<PAGE>   16
                 (A)      In case any legal proceeding or claim including any
                 investigatory proceeding, is brought or made against a party in
                 a manner for which indemnification may be provided under This
                 Article VII, the party claiming indemnification shall promptly
                 notify the other party with the delivery of the Claim Notice.
                 The party receiving such notice shall have the right to control
                 and assume the defense of any such legal proceeding or claim,
                 including the employment of counsel satisfactory to the
                 indemnifying  party. If the party to whom notice was given
                 controls and assumes the defense of any proceeding or claim,
                 other party shall have the right to employ separate counsel but
                 the fees and expenses of such counsel shall be at the expense
                 of the other party unless the representation of both parties by
                 the same counsel would be inappropriate due to any actual or
                 potential conflicts of interest. The indemnifying party shall
                 not be liable for the fees and expenses of more than one
                 separate firm of attorneys at any one time in connection with
                 any one legal proceeding or claim or substantially similar
                 related proceedings and claims.

                 (B)      Notwithstanding anything of the contrary in Section A
                 above, the indemnified party shall be entitled to reasonable
                 compensation for costs of defense, including reasonable
                 attorneys fees, in the event that (i) the employment of
                 separate counsel has been authorized by indemnifying party,
                 (ii) indemnifying party has failed to defend diligently any
                 Claims, or (iii) the parties to such action (including any
                 impleaded parties) include Seller and Buyer, and indemnified
                 party has been advised by legal counsel that there may be legal
                 defenses available to it which are different from, in addition
                 to or inconsistent with, the legal defenses available to the
                 indemnifying party, or that the indemnified party's interest
                 may be adverse in whole or in part to the interest of
                 indemnifying party. The indemnifying party shall not, in the
                 defense of any such Claims, except with the prior written
                 consent of the indemnified party, consent to the entry of any
                 judgment or enter into any settlement which does not include as
                 an unconditional term, the release by the claimant or the
                 plaintiff of the indemnified party from all further liability
                 in respect to any such Claims.

         7.05.03    The indemnification obligations under this Article VII (or
         otherwise under this Agreement) shall not apply to any settlements
         effected without the consent of an indemnifying party.  The
         indemnification obligations under this Article VII (or otherwise under
         this Agreement) shall not be deemed to create any rights of subrogation
         or other rights in any insurer or third party.

7.06     WAIVER OF REPRESENTATIONS. SELLER EXPRESSLY DISCLAIMS AND NEGATES AND
BUYER HEREBY WAIVES, ANY REPRESENTATION OR WARRANTY WITH RESPECT TO (A) THE
QUALITY, QUANTITY OR VOLUME OF THE RESERVES, IF ANY, OF OIL, GAS OR OTHER
HYDROCARBONS IN OR UNDER THE SUBJECT PROPERTIES; (B) THE WORKING INTEREST AND
NET REVENUE INTEREST PERCENTAGES SET FORTH IN EXHIBIT A HERETO; AND (C) THE
SAMPLES, OR 



PURCHASE AND SALE AGREEMENT, PAGE 16
<PAGE>   17
CONDITION OF ANY OF THE SUBJECT PROPERTIES OR ANY PART THERETO. THE ITEMS OF
PERSONAL PROPERTY, EQUIPMENT, IMPROVEMENTS, FIXTURES AND APPURTENANCES CONVEYED
AS PART OF THE PROPERTIES ARE SOLD, AND BUYER ACCEPTS SUCH ITEMS "AS IS, WITH
ALL FAULTS". THERE ARE NO WARRANTIES THAT EXTEND BEYOND THE FACE OF THIS
AGREEMENT. BUYER ACKNOWLEDGES THAT THIS WAIVER IS CONSPICUOUS.

7.07     Liabilities Retained by Seller. Seller shall remain liable for (i)
damages arising from personal injury or death, (ii) the nonpayment of royalties
which were the responsibility of Seller to pay (not to include, however,
royalties payable out of suspended funds to be transferred to Buyer pursuant to
Section 10.03 hereof) or the incorrect payment of royalties, to the extent and
only to the extent such payment was not made in accordance with terms of the
leases and (iii) any and all actions, claims and causes of action, lease
operating expenses and capital costs to the extent, and only to the extent any
of such damages, expenses or costs arise from acts, circumstances or events
occurring with respect to the ownership of the Subject Properties prior to the
Effective Date.

                                  ARTICLE VIII
                            LIMITATIONS OF LIABILITY

8.01     Exclusive Remedy. If the Closing occurs, the sole and exclusive remedy
of the Buyer and the Seller with respect to the purchase and sale of the Subject
Properties shall be pursuant to the express provisions of this Agreement. Buyer
and Seller shall be deemed to have waived, to the fullest extent permitted under
applicable law, any rights of contribution and any and all rights, claims and
causes of action which may exist against Seller or Buyer, respectively, arising
under or based on any federal, state or local statute, law, ordinance, rule or
regulation or common law or otherwise, except as specifically set forth in this
Agreement.

8.02     Waiver of Right to Rescind. Seller and Buyer acknowledge that if this
Agreement is not terminated and the transaction contemplated hereby is
closed, the payment of money, as limited by the terms of this Agreement,
shall be adequate compensation for breach of any representation, warranty,
covenant or agreement contained herein or for any other claim arising in
connection with or with respect to the transactions contemplated in this
Agreement. As the payment of money shall be adequate compensation, Buyer
and Seller waive any right to rescind the transactions contemplated by this
Agreement.

8.03     Time Limitation. Notwithstanding any provision hereof to the
contrary, it is understood and agreed that any and all liabilities of Seller
under this Agreement, if any, shall expire and terminate and no longer be
enforceable for all periods on and after two (2) years from the Closing
except as to Liabilities Retained by Seller provided in Section 7.07 above,
for which such period of time shall be three (3) years from the Closing. On
and after two (2) years from the Closing, except as to Liabilities Retained
by Seller provided for in Section 7.07 which time shall be three (3) years
from the Closing, Buyer shall not be entitled to make any claim against
Seller for any cause attributable to any time period under this Agreement
or otherwise, including without limitation, rights of contribution arising
under or based on any federal, state or local statute, law, ordinance, rule
or


PURCHASE AND SALE AGREEMENT, PAGE 17
<PAGE>   18
regulation or common law or otherwise. In the event any law, rule or regulation
requires a longer time period before Seller will be exempted from all liability
under this provision, this provision shall be deemed amended, to the extent and
only to the extent required by law and only as to that portion of the Subject
Properties as so required, to extend the limitation period as so required.

8.04     Liability Cap. Seller's liability, if any, under this Agreement
shall never exceed, and Seller shall have no obligation for the payment of any
amount in excess of the Base Purchase Price.

8.05     Damage Limitation. Notwithstanding anything to the contrary
herein, in no event shall any party hereunder be liable to the other for
any exemplary, punitive, special, indirect, consequential, remote or
speculative damages; provided, however, that if Seller is held liable to
a third party for any of such damages and the Buyer is obligated to
indemnity Seller for the matter that gave rise to such damages pursuant to
this Agreement, then the Buyer shall be liable for, and obligated to reimburse
Seller for, such damages.

                                   ARTICLE IX
                                  TERMINATION

9.01     Termination of Agreement. This Agreement and the transactions
contemplated hereby may be terminated upon written notice from the party
electing to terminate this Agreement, in the following instances:

         (A)     By Seller if the conditions set forth in Section 5.01 are
         not satisfied in all material respects or waived as of the Closing.

         (B)     By Seller or Buyer, if at or before Closing, for any reason
         under this Agreement, properties are excluded from the sale and/or
         other adjustments to the Base Purchase Price are made or proposed to
         be made, which have a cumulative value, in excess of four percent(4%)
         of the Base Purchase Price.

         (C)     By Buyer if the conditions set forth in Section 5.02 are not
         satisfied in all material respects or waived as of Closing.

         (F)     At any time by the mutual written agreement of Buyer and
         Seller.

9.02     Liabilities Upon Termination. If this Agreement is terminated prior
to Closing for any reason other than those set forth in Section 9.01 or is
breached (it shall be deemed a breach of this Agreement if the conditions set
forth in Section 5.02 are not satisfied through the fault, neglect or failure to
act of Buyer, or if the conditions set forth in Section 5.01 are not satisfied
through the fault, neglect or failure to act of Seller) nothing contained herein
shall be construed to limit Seller's or Buyer's legal or equitable remedies
including, without limitations damages for the breach or failure of any
representation, warranty, covenant or agreement contained herein and the right
to enforce specific performance of this Agreement.

                                 MISCELLANEOUS

10.01    Files and Records. As soon as practicable, but not more than ten
(10) days after Closing, or such other time frame as is agreed to by the
Parties, Seller shall deliver or cause to be delivered to Buyer all original
records and files, including, without limitation, regulatory files, joint
interest billings, revenue files, division orders, division order files,
Buyer's statements, payout calculations, well logs, well files, land records,
contracts, maps and seismic information (to the extent the same are in
Seller's possession and capable of being legally transferred by Seller
without unreasonable cost or consent) relating to the Subject Properties. In
the event Seller wishes to keep copies of such files and records, Seller may
make and retain copies thereof at its sole expense. The expense of copying
such files shall be borne by Seller. Buyer shall retain all of such files
for four (4) years from Closing and shall make such files available to
Seller for its review at any time during normal business hours.

10.02    Survival of Representation, Warranties and Covenants. Unless
otherwise specified herein, the obligations and liabilities of the
Parties under each of their representations, warranties and covenants
contained in this Agreement shall survive the Closing and the execution and
delivery of the documents to be delivered at Closing and remain in full force
and effect.

10.03    Suspended Funds. All third party funds held by Seller in suspense
will be transferred to Buyer at Closing. Buyer shall indemnity and hold
harmless Seller from and against any claims, loss, cost or expense
whatsoever arising from improper, untimely or other mispayment of such
suspended funds after Closing when caused by Buyer. In the event interest
is owed on suspended funds attributable to periods prior to the Effective
Date, Seller will bear the liability for the payment of such interest and
will indemnify Buyer in the same manner as Buyer indemnifies Seller under
Section 7.05 from and against the payment of such interest.

10.04    Notices. All communication or notices required or permitted to be
given under this Agreement shall be in writing, and any communication or
notice shall be deemed to have been duly made if actually delivered,
including delivery by facsimile transmission, receipt of which has been duly
acknowledged, or if mailed by registered or certified mail, postage prepaid,

incorporated in this Agreement by this reference and constitute a part of this
Agreement. All references to Exhibit A herein shall be deemed to include
Exhibits A-1, A-2 and A-3 unless the context clearly indicates a contrary

                [COTTON VALLEY RESOURCES CORPORATION LETTERHEAD]

                                LETTER AGREEMENT

         This Letter Agreement is made and entered into this 5th day of
November, 1997, by and among M & M Directional Services, ("M & M"), Mike
Burton, ("Burton"), Mark Milam, ("Milam") and Cotton Valley Resources
Corporation, an Ontario corporation, ("CVR").

         1.      CVR will cause Mustang Horizontal Services, Inc., ("MHS") to
be formed as a Nevada corporation. The business of MHS will be primarily to
provide integrated horizontal drilling services to the petroleum industry. MHS
will initially be capitalized at 6,000,000 shares at $0.05 per share. CVR will
subscribe for 5,000,000 shares by delivering $250,000 cash into an MHS bank
account in two tranches of $125,000 each. The first deposit will be made upon
formation and the second deposit will be 30-60 days later.

         2.      CVR will establish a line of credit of $700,000 to be used by
MHS for the acquisition and building of its tools and equipment which would be
secured by all of the assets of MHS until repaid.

         3.      1,000,000 shares of MHS will be deposited into a modified
employee stock ownership plan (MESOP) to be administered by CVR. On behalf of
the officers, directors and employees of MHS, as well as the employees of CVR
working on MHS matters, CVR will subscribe for 1,000,000 shares by delivering
$50,000 cash into an MHS bank account in two tranches of $25,000 each. The
first deposit will be upon formation and the second deposit will be 30-60 days
later.

         4.      320,000 of the MESOP shares will be allocated to Burton and 
Milam (as divided between the two in amounts provided in written notice to CVR
within thirty days of the date hereof). 200,000 of the MESOP shares will be
reserved for allocation by MHS for new MHS employees as they are hired. 320,000
of the MESOP shares will be allocated to Jim Hogue and Gene Soltero in equal
amounts and 160,000 shares will be reserved for allocation by Gene Soltero and
Jim Hogue to CVR employees. Each awardee will receive 4% of his stock award on
the date he starts work. At the end of each month, each awardee will receive a
stock certificate representing another 4%. At the end of two years of
employment, the awardee will be fully vested in his MESOP shares. Any employee
who ceases to be employed, or any reason, will not receive any shares following
the shares delivered at the end of the month preceding the month in which
employment ceases. Non-vested shares previously awarded will be returned to the
MHS or CVR pool (as appropriate) for new awards upon the cessation of
employment of the person who loses rights to those shares.
<PAGE>   2
     5.  A non-qualified stock option plan will be established consisting of a
maximum of 4,000,000 options (the "Options") where each Option will be the right
for a period of five years to purchase one share of MHS for $0.05 per share.
1,280,000 Options will be awarded to Burton and Milam (as divided between the
two as provided by written notice to CVR within thirty days of the date hereof)
and 800,000 Options will be reserved for award to MHS employees. 1,440,000
Options will be awarded to Jim Hogue and Gene Soltero in equal amounts and
480,000 Options will be reserved for award to CVR employees by Jim Hogue and
Gene Soltero. Each awardee will vest in the rights to exercise the Options at
the rate of one-third of each award at the end of each of the first three years
following the date of award. Any employee who ceases to be employed will lose
all rights to Options that have not vested and such Options will be returned to
the MHS or CVR pool (as appropriate) for reissuance by either the management of
MHS or the management of CVR.

    6.  If, within three years following initial formation of MHS, CVR has not
filed a registration statement with the United States Securities and Exchange
Commission ("SEC") providing for the spin-off of MHS into the public markets,
all holders of MHS shares and Options shall have the right to convert their MHS
shares and Options into CVR shares and Options according to a formula based on
the then market capitalization of CVR and the relative contribution of MHS to
that market capitalization. The calculations of the relative contributions
shall be based on the average of three published valuations by independent oil
and gas stock analysts. MHS and CVR shall each choose an analyst and those two
analysts shall chose the third.

    7.  M & M will sell certain technology and equipment as listed on Exhibit A,
attached and made a part hereof, at a purchase price of $550,000 and will
provide the services of Burton and Milam to act as unpaid full-time consultants
for November, 1997 and December, 1997. M & M will continue to provide certain
additional services to MHS for a retainer of $29,700 per month less the salaries
and benefits paid to Burton and Milam by MHS. The parties acknowledge that M &
M, Burton and/or Milam have oil and gas property interests in Illinois. Burton
and Milam agree that they will contribute 100% of normal business hours,
services, technology, licensing, patents and expertise solely for the benefit of
MHS. M & M, Milam and Burton will be reimbursed by MHS for any out of pocket
expenses incurred on behalf of MHS. Effective January 1, 1998, Milam and Burton
will become full-time employees of MHS at salaries and benefits designated by M
& M, but which shall be less than $29,700 per month. To the extent that M & M
currently has existing administrative and support personnel which augment and
facilitate the services or activities of Burton and Milam, such personnel or
their replacements may continue to provide such administrative and support
services; however, it is specifically understood that any of the technical or
management responsibilities of MHS that are provided by M & M will be solely
performed by Burton and Milam.

    8.  Milam and Burton will decide among themselves the titles they have
within MHS. Gene Soltero, Jim Hogue and William McGuire will be the directors
of MHS. Burton & Milam will be awarded 60,000 CVR options at the closing AMEX
market price on the date hereof, which will vest over three years. The amount
allocated to each Burton & Milam will be reported to CVR within thirty days
after the date of signing of this agreement.
<PAGE>   3
     9.   MHS will provide horizontal drilling services for CVR and its
subsidiaries at 85% of the then current market rate. CVR will provide executive
management and administrative services for MHS at cost plus 20%.

     10.  CVR will use its best efforts to acquire drilling and/or workover
rigs in a wholly-owned subsidiary to be named Mustang Drilling Company ("MDC").
CVR will cause MDC to cooperate with MHS and provide the vertical services
whenever MHS obtains contracts that require a combination of vertical and
horizontal services.

Company hereby makes the following representations and warranties to the
Purchasers:

                 (a)      Organization and Qualification. The Company is a
corporation, duly incorporated, validly existing and in good standing under the
laws of the jurisdiction of its incorporation, with the requisite corporate
power and authority to own and use its properties and assets and to carry on
its business as currently conducted. The Company has no subsidiaries other than

validly existing and in good standing under the laws of the jurisdiction of its
incorporation, with the full corporate power and authority to own and use its
properties and assets and to carry on its business as currently conducted. Each
of the Company and the Subsidiaries is duly qualified to do business and is in
good standing as a foreign corporation in each jurisdiction in which the nature
of the business conducted or property owned by it makes such qualification
necessary, except where the failure to be so qualified or in good standing, as
the case may be, could not, individually or in the aggregate, (x) adversely
affect the legality, validity or enforceability of the Transaction

                                      -4-
<PAGE>   6
Documents, (y) have a material adverse effect on the results of operations,
assets, prospects, or condition (financial or otherwise) of the Company and the
Subsidiaries, taken as a whole, or (z) adversely impair the Company's ability
to perform fully on a timely basis its obligations under any Transaction
Document (any of the foregoing, a "Material Adverse Effect").

                 (b)      Authorization; Enforcement. The Company has the
requisite corporate power and authority to enter into and to consummate the
transactions contemplated by the Transaction Documents and otherwise to carry
out its obligations thereunder. The execution and delivery of each of the
Transaction Documents by the Company and the consummation by it of the
transactions contemplated thereby have been duly authorized by all necessary
action on the part of the Company. Each of the Transaction Documents has been
duly executed by the Company and when delivered in accordance with the terms
hereof shall constitute the legal, valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or
affecting generally the enforcement of, creditors' rights and remedies or by
other equitable principles of general application. Neither the Company nor any
Subsidiary is in violation of any of the provisions of its respective articles
of amalgamation, certificate of incorporation, by-laws or other charter
documents.

                 (c)      Capitalization. The authorized, issued and
outstanding capital stock of the Company is set forth in Schedule 2.1(c). No
shares of Common Stock are entitled to preemptive or similar rights, nor is any
holder of the Common Stock entitled to preemptive or similar rights arising out
of any agreement or understanding with the Company by virtue of any of the
Transaction Documents. Except as disclosed in Schedule 2.1(c), there are no
outstanding options, warrants, script rights to subscribe to, calls or
commitments of any character whatsoever relating to, or, except as a result of
the purchase and sale of the Debentures and Warrants hereunder, securities,
rights or obligations convertible into or exchangeable for, or giving any
person any right to subscribe for or acquire any shares of Common Stock, or
contracts, commitments, understandings, or arrangements by which the Company or
any Subsidiary is or may become bound to issue additional shares of Common
Stock, or securities or rights convertible or exchangeable into shares of Common
Stock. To the knowledge of the Company, except as specifically disclosed in the
SEC Documents or Schedule 2.1(c), no Person beneficially owns (as determined
pursuant to Rule 13d-3 promulgated under the Exchange Act) or has the right to
acquire by agreement with or by obligation binding upon the Company, beneficial
ownership of in excess of 5% of the Common Stock.

                 (d)      Issuance of Debentures and Warrants. The Debentures
and the Warrants are duly authorized, and, when issued in accordance with the
terms hereof, shall be validly issued, fully paid and nonassessable, free and
clear of all Liens. The Company has and at all times while the Debentures and
the Warrants are outstanding will maintain an adequate reserve of duly
authorized shares of Common Stock to enable it to perform its conversion,
exercise and other obligations under this Agreement, the Debentures and the
Warrants, and in no circumstances shall such reserved and available shares of
Common Stock be less than the sum

                                      -5-

were effected on the Original Issue Date or the Filing Date (as defined in the
Registration Rights Agreement), whichever yields a lower Conversion Price and
(B) the number of shares of Common Stock as are issuable as payment of interest
on the Debentures, and (ii) the number of Underlying Shares as are issuable

representations and such Purchaser hereby consents to such reliance. Each
Purchaser hereby agrees to cooperate with the Company if, as required by law or
the Commission to confirm the availability of an exemption from the
registration requirements of the Securities Act for the transactions
contemplated herein, the Company shall reasonably request additional
information from such Purchaser.

                 The Company acknowledges and agrees that the Purchasers make
no representations or warranties with respect to the transactions contemplated
hereby other than those specifically set forth in this Section 2.2.

                                  ARTICLE III

                        OTHER AGREEMENTS OF THE PARTIES

         3.1     Transfer Restrictions. (a) Securities may only be disposed of
pursuant to an effective registration statement under the Securities Act, to
the Company or pursuant to an available exemption from or in a transaction not
subject to the registration requirements thereof. In connection with any
transfer of any Securities other than pursuant to an effective registration
statement or to the Company, the Company may require the transferor thereof to
provide to the Company an opinion of counsel selected by the transferor, the
form and substance of which opinion shall be reasonably satisfactory to the
Company, to the effect that such transfer does not require registration under
the Securities Act. Notwithstanding the foregoing, the Company hereby consents
to and agrees to register (i) any transfer of Securities by one Purchaser to
another Purchaser, and agrees that no documentation other than executed
transfer documents shall be required for any such transfer, and (ii) any
transfer by any Purchaser to an Affiliate (as such term is defined under Rule
405 promulgated under the Securities Act) of such Purchaser or to an Affiliate
of another Purchaser, or any transfers among any such Affiliates provided the
transferee certifies to the Company that it is an "accredited investor" as
defined in Rule 501(a) under the Securities Act. Any such Purchaser or
Affiliate transferee shall have the rights of a Purchase under this Agreement
and the Registration Rights Agreement.

                 (b)      The Purchasers agree to the imprinting, so long as is
required by this Section 3.1 (b), of the following legend on the Securities:

                 NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE
         SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN REGISTERED WITH
         THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF
         ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
         ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
         EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT
         TO AN

                                      -15-
<PAGE>   17
         AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
         REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
         APPLICABLE STATE SECURITIES LAWS.

         [FOR DEBENTURES ONLY] THIS DEBENTURE IS SUBJECT TO CERTAIN
         RESTRICTIONS ON CONVERSION SET FORTH IN SECTION 3.8 OF THE CONVERTIBLE
         DEBENTURE PURCHASE AGREEMENT, DATED AS OF DECEMBER 30, 1997, AMONG
         COTTON VALLEY RESOURCES CORPORATION (THE "COMPANY") AND THE ORIGINAL
         HOLDER HEREOF. A COPY OF THAT AGREEMENT IS ON FILE AT THE PRINCIPAL
         OFFICE OF THE COMPANY.

                 Underlying Shares shall not contain the legend set forth above
if the conversion of Debentures, exercise of Warrants or other issuances of
Underlying Shares, as the case may be, occurs at any time while an Underlying
Securities Registration Statement is effective under the Securities Act or, in
the event there is not an effective Underlying Securities Registration
Statement at such time, if in the opinion of counsel to the Company such legend
is not required under applicable requirements of the Securities Act (including
judicial interpretations and pronouncements issued by the staff of the
Commission). The Company agrees that it will provide each Purchaser, upon
request, with a certificate or certificates representing Underlying Shares,
free from such legend at such time as such legend is no longer required
hereunder. The Company may not make any notation on its records or give
instructions to any transfer agent of the Company which enlarge the
restrictions of transfer set forth in this Section 3.1(b).

         3.2     Acknowledgement of Dilution. The Company acknowledges that the
issuance of Underlying Shares upon (i) conversion of the Debentures and as
payment of interest thereon and (ii) exercise of the Warrants may result in
dilution of the outstanding shares of Common Stock, which dilution may be
substantial under certain market conditions. The Company further acknowledges
that its obligation to issue Underlying Shares in accordance with the
Debentures and the Warrants is unconditional and absolute regardless of the
effect of any such dilution.

         3.3     Furnishing of Information. As long as the Purchasers own
Securities, the Company covenants to timely file all reports required to be
filed by the Company after the date hereof pursuant to Section 13(a) or 15(d)
of the Exchange Act. If at any time prior to the date on which the Purchasers
may resell all of their Underlying Shares without volume restrictions pursuant
to Rule 144(k) promulgated under the Securities Act (as determined by counsel
to the Company pursuant to a written opinion letter to such effect, addressed
and acceptable to the Company's transfer agent for the benefit of and
enforceable by the Purchasers) the Company is not required to file reports
pursuant to such sections, it will prepare and furnish to the Purchasers and
make publicly available in accordance with Rule 144(c) promulgated under the
Securities Act annual and quarterly financial statements, together with a
discussion and analysis of such financial statements in form and substance
substantially similar to those that would otherwise be required to be included
in reports required by Section 13(a) or 15(d) of the Exchange Act in the time
period that such filings would have been required to have been made under the
Exchange Act. The Company further covenants that it will take such further
action



                                      -16-
<PAGE>   18
as any holder of Securities may reasonably request, all to the extent required
from time to time to enable such Person to sell Securities without registration
under the Securities Act within the limitation of the exemptions provided by
Rule 144 promulgated under the Securities Act, including the legal opinion
referenced above in this Section. Upon the request of any such Person, the
Company shall deliver to such Person a written certification of a duly
authorized officer as to whether it has complied with such requirements.

         3.4     Use of Disclosure Materials. The Company consents to the use
of the Disclosure Materials and any information provided by or on behalf of the
Company pursuant to Section 3.3, and any amendments and supplements thereto, by
the Purchasers in connection with resales of the Securities other than pursuant
to an effective registration statement.

         3.5     Blue Sky Laws. In accordance with the Registration Rights
Agreement, the Company shall qualify the Underlying Shares under the securities
or Blue Sky laws of such jurisdictions as the Purchasers may request and shall
continue such qualification at all times until the Purchasers notify the
Company in writing that they no longer own Securities; provided, however, that
neither the Company nor its Subsidiaries shall be required in connection
therewith to qualify as a foreign corporation where they are not now so
qualified or to take any action that would subject the Company to general
service of process in any such jurisdiction where it is not then so subject.

         3.6     Integration. The Company shall not and shall use its best
efforts to ensure that no Affiliate shall sell, offer for sale or solicit
offers to buy or otherwise negotiate in respect of any security (as defined in
Section 2 of the Securities Act) that would be integrated with the offer or
sale of the Securities in a manner that would require the registration under
the Securities Act of the issue or sale of the Securities to the Purchasers.

         3.7     Increase in Authorized Shares. At such time as the Company
would be, if a notice of conversion or exercise (as the case may be) were to be
delivered on such date, precluded from (a) converting the full outstanding
principal amount of Debentures (and paying any accrued but unpaid interest in
respect thereof in shares of Common Stock) that remain unconverted at such date
or (b) honoring the exercise in full of the Warrants due to the unavailability
of a sufficient number of shares of authorized but unissued or re-acquired
Common Stock, the Board of Directors of the Company shall promptly (and in any
case within 30 Business Days from such date) prepare and mail to the
shareholders of the Company proxy materials requesting authorization to amend
the Company's restated certificate of incorporation to increase the number of
shares of Common Stock which the Company is authorized to issue to at least a
number of shares equal to the sum of (i) all shares of Common Stock then
outstanding, (ii) the number of shares of Common Stock issuable on account of
all outstanding warrants, options and convertible securities (other than the
Debentures and the Warrants) and on account of all shares reserved under any
stock option, stock purchase, warrant or similar plan, (iii) 200% of the number
of Underlying Shares as would then be issuable upon a conversion in full of the
then outstanding Debentures and as payment of all future interest thereon in
shares of common Stock in accordance with the terms of this Agreement and the

                                      -17-
<PAGE>   19
Debentures and (iv) such number of Underlying Shares as would then be issuable
upon the exercise in full of the Warrants. In connection therewith, the Board
of Directors shall (x) adopt proper resolutions authorizing such increase, (y)
recommend to and otherwise use its best efforts to promptly and duly obtain
stockholder approval to carry out such resolutions (and hold a special meeting
of the shareholders no later than the 60th day after delivery of the proxy
materials relating to such meeting) and (z) within 5 Business Days of obtaining
such shareholder authorization, file an appropriate amendment to the Company's
certificate of incorporation to evidence such increase.

         3.8     Purchaser Ownership of Common Stock. In no event shall a
Purchaser be permitted to use its ability to convert Debentures or exercise its
Warrants to the extent that such conversion or exercise would result in that
Purchaser beneficially owning (for purposes of Rule 13d-3 under the Exchange
Act and the rules thereunder) in excess of 4.999% of the then issued and
outstanding shares of Common Stock, including shares issuable upon conversion
of the Debentures held by such Purchaser after application of this Section 3.8.
To the extent that the limitation contained in this Section 3.8 applies, the
determination of whether Debentures are convertible (in relation to other
securities owned by a Purchaser) and of which Debentures are convertible shall
be in the sole discretion of such Purchaser, and the submission of Debentures
for conversion shall be deemed to be such Purchaser's determination of whether
such Debentures are convertible (in relation to other securities owned by a
Purchaser) and of which Debentures are convertible, in each case subject to
such aggregate percentage limitation, and the Company shall have no obligation
to verify or confirm the accuracy of such determination.  Nothing contained
herein shall be deemed to restrict the right of a Purchaser to convert
Debentures or exercise Warrants at such time as such conversion or exercise
will not violate the provisions of this Section 3.8. The provisions of this
Section may be waived by a Purchaser as to itself (and solely as to itself)
upon not less than 65 days prior notice to the Company, and the provisions of
this Section 3.8 shall continue to apply until such 65th day (or later, if
stated in the notice of waiver).

         3.9     Listing of Underlying Shares. The Company shall (1) not later
than the fifth Business Day following the Closing Date prepare and file with
the AMEX (as well as any other national securities exchange, market or trading
facility on which the Common Stock is then listed) an additional shares listing
application covering at least the sum of (i) two times the number of Underlying
Shares as would be issuable upon a conversion in full of (and as payment of
interest in respect of) the Debentures, assuming such conversion occurred on the
Original Issue Date or the Filing Date (whichever yields a lower Conversion
Price) and (ii) the number of Underlying Shares then issuable upon exercise in
full of the maximum number of Warrants which could be issued upon conversion of
the outstanding Debentures on either the Closing Date or the Filing Date
(whichever yields a higher number of Underlying Shares) (2) take all steps
necessary to cause the such shares to be approved for listing on the AMEX (as
well as on any other national securities exchange or market on which the Common
Stock is then listed) as soon as possible thereafter, and (3) provide to the
Purchasers evidence of such listing, and the Company shall maintain the listing
of its Common Stock on such exchange or market. In addition, if at any time the
number of shares of Common Stock issuable on conversion of all

                                      -18-
<PAGE>   20
then outstanding Debentures, on account of accrued and unpaid interest thereon
and upon exercise in full of the Warrants is greater than the number of shares
of Common Stock theretofore listed with the AMEX (and any such other national
securities exchange, market or trading facility), the Company shall promptly
take such action (including the actions described in the preceding sentence) to
file an additional shares listing application with the AMEX (and any such other
national securities exchange, market or trading facility) covering at least a
number of shares equal to the sum of (x) 200% of the sum of (A) the number of
Underlying Shares as would then be issuable upon a conversion in full of the
Debentures and (B) the number of Underlying Shares as would be issuable as
payment of interest on the Debentures, and (y) the number of Underlying Shares
as would then be issuable upon exercise of the maximum number of Warrants which
could then be issued upon conversion of the then outstanding Debentures.

         3.10    Use of Proceeds. The Company shall use all of the proceeds
from the sale of the Securities for working capital and general corporate
purposes, including, without limitation, for the purchase of equipment and
other assets, and not for the satisfaction of any portion of Company debt or to
redeem Company equity or equity-equivalent securities.  Pending application of
the proceeds of this placement in the manner permitted hereby the Company will
invest such proceeds in interest bearing accounts and/or short-term, investment
grade interest bearing securities.

         3.11    Notice of Breaches. Each of the Company and each Purchaser
shall give prompt written notice to the other of any breach by it of any
representation, warranty or other agreement contained in any Transaction
Document, as well as any events or occurrences arising after the date hereof,
which would reasonably be likely to cause any representation or warranty or
other agreement of such party, as the case may be, contained in the Transaction
Document to be incorrect or breached as of such Closing Date. However, no
disclosure by either party pursuant to this Section 3.11 shall be deemed to
cure any breach of any representation, warranty or other agreement contained in
any Transaction Document.

         Notwithstanding the generality of the foregoing, the Company shall
promptly notify the Purchasers of any notice or claim (written or oral) that it
receives from any lender of the Company to the effect that the consummation of
the transactions contemplated by the Transaction Documents violates or would
violate any written agreement or understanding between such lender and the
Company, and the Company shall promptly furnish by facsimile to the holders of
the Debentures a copy of any written statement in support of or relating to such
claim or notice.

         3.12    Conversion Obligations of the Company. The Company shall honor
conversions of the Debentures and exercises of the Warrants and shall deliver
Underlying Shares in accordance with the respective terms and conditions and
time periods set forth in the Debentures and the Warrants.

         3.13    Right of First Refusal; Subsequent Registrations; Certain
Corporate Actions. (a) Except for the pending transaction with Cambrian Capital
Corporation which has been disclosed



                                      -19-
<PAGE>   21
to the Purchasers prior to the date hereof, the Company shall not, directly or
indirectly, without the prior written consent of the Purchasers, offer, sell,
grant any option to purchase, or otherwise dispose (or announce any offer,
sale, grant or any option to purchase or other disposition) of any of its or
its Affiliates equity, equity-equivalent or derivative securities (a
"Subsequent Financing") for a period of 180 days after the Closing Date, except
(i) the granting of options or warrants to employees, officers and directors,
and the issuance of shares upon exercise of options granted, under any stock
option plan heretofore or hereinafter duly adopted by the Company, (ii) shares
issued upon exercise of any currently outstanding warrants and upon conversion
of any currently outstanding convertible preferred stock in each case disclosed
in Schedule 2.1 (c), and (iii) shares of Common Stock issued upon conversion of
the Debentures, as payment of interest thereon, or upon exercise of the
Warrants in accordance with their respective terms, unless (A) the Company
delivers to Palisades a written notice (the "Subsequent Financing Notice") of
its intention to effect such Subsequent Financing, which Subsequent Financing
Notice shall describe in reasonable detail the proposed terms of such
Subsequent Financing, the amount of proceeds intended to be raised thereunder,
the Person with whom such Subsequent Financing shall be effected, and a term
sheet or similar document relating thereto shall be attached to such Subsequent
Financing Notice and (B) Palisades shall not have notified the Company by 5:00
p.m. (New York City Time) on the tenth (10th) Trading Day after its receipt of
the Subsequent Financing Notice of its willingness to cause any of the
Purchasers to provide (or to cause its sole designee to provide), subject to
completion of mutually acceptable documentation, financing to the Company on
substantially the terms set forth in the Subsequent Financing Notice. If
Palisades shall fail to notify the Company of its intention to enter into such
negotiations within such time period, the Company may effect the Subsequent
Financing substantially upon the terms and to the Persons (or Affiliates of
such Persons) set forth in the Subsequent Financing Notice; provided, that the
Company shall provide Palisades with a second Subsequent Financing Notice, and
Palisades shall again have the right of first refusal for a period of five
Trading Days from the date of its receipt of such second Subsequent Financing
Notice, if the Subsequent Financing subject to the initial Subsequent Financing
Notice shall not have been consummated for any reason on the terms set forth in
such Subsequent Financing Notice within thirty (30) Trading Days after the date
of the initial Subsequent Financing Notice with the Person (or an Affiliate of
such Person) identified in the Subsequent Financing Notice.

         (b)     Except Underlying Shares and other "Registrable Securities"
(as such term is defined in the Registration Rights Agreement) to be registered
in accordance with the Registration Rights Agreement, and other than Company
securities to be registered for resale in connection with financings permitted
pursuant to paragraph (a)(i) through (iii) of this Section, the Company shall
not, without the prior written consent of Palisades, (i) issue or sell any of
its or any of its Affiliates' equity or equity-equivalent securities pursuant
to Regulation S promulgated under the Securities Act, or (ii) register for
resale any securities of the Company for a period of not less than 90 Trading
Days after the date that the Underlying Securities Registration Statement is
declared effective by the Commission. Any days that a Purchaser is not
permitted to sell Underlying Shares under the Underlying Securities
Registration Statement shall be added to such 90 Trading Day period for the
purposes of (i) and (ii) above.

<PAGE>   22
                 (c)      As long as there are Debentures outstanding, the
Company shall not and shall cause the Subsidiaries not to, without the consent
of the holders of the Debentures, (i) amend its articles of amalgamation,
bylaws or other charter documents so as to adversely affect any rights of the
holders of Debentures; (ii) repay, repurchase or offer to repay, repurchase or
otherwise acquire shares of its Common Stock other than Underlying Shares in
accordance with the Transaction Documents; or (iii) enter into any agreement
with respect to any of the foregoing.

         3.14    The Warrants. The Company shall issue and deliver Warrants
upon the conversion of Debentures in accordance with the terms of the
Debentures. Warrants shall be exercisable through December 31, 2001 into Common
Stock pursuant to the terms of the Warrants.

         3.15    Security Documents. Simultaneously with the execution of this
Agreement, the Company, the Purchasers and certain of the Company's
Subsidiaries shall enter into (i) the Guaranty, pursuant to which, in
consideration of the substantial benefit they will derive as a result of the
transactions contemplated hereby, such Subsidiaries will guaranty the
Obligations (as defined in the Security Agreement) and (ii) the Security
Agreement and the Cash Collateral Agreement pursuant to which such Subsidiaries
will pledge Collateral (as defined in the Security Agreement) as security for
the Obligations.

                                 MISCELLANEOUS

         5.1     Fees and Expenses. The Company shall pay at the Closing
$30,000 to Palisades for payment to RSPA&B for the preparation and negotiation
of the Transaction Documents and for the due diligence expenses and
disbursements incurred in connection with the transactions contemplated hereby;
provided that if the transactions contemplated hereby do not close solely due
to the fact that a Purchaser is not satisfied with its due diligence or because
of a Material Adverse Effect prior to Closing, then such amount shall be
$10,000. Other than the amounts contemplated by the immediately preceding
sentence, and except as set forth in the Registration Rights Agreement, each
party shall pay the fees and expenses of its advisers, counsel, accountants and
other experts, if any, and all other expenses incurred by such party incident
to the negotiation, preparation, execution, delivery and performance of this
Agreement. The Company shall pay all stamp and other taxes and duties levied in
connection with the issuance of the Debentures pursuant hereto.  The Purchasers
shall be responsible for their own respective tax liability that may arise as a
result of the investment hereunder or the transactions contemplated by this
Agreement. Except pursuant to the terms of this Agreement, if the Company sells
any securities to any of the Purchasers during the two-year period following
the Closing Date, the Company shall pay to Palisades a cash fee of 5% on any
amount up to $5,000,000, 4% on any amount between $5,000,000 and $10,000,000,
3% on any amount between $10,000,000 and $15,000,000 and 2.5% on any amount
greater than $15,000,000 of capital received by the Company from the sale of
such securities and Palisades shall pay any fees and expenses owed to Liviakis
under the consulting agreement between the Company and Liviakis arising as a
result of the transactions contemplated hereunder.

         5.2     Entire Agreement; Amendments. This Agreement, together with
the Exhibits and Schedules hereto, the Debentures, the Guaranty, the Warrants,
the Security Agreement, the Cash Collateral Agreement and the Registration
Rights Agreement contain the entire understanding of the parties with respect
to the subject matter hereof and supersede all prior agreements and
understandings, oral or written, with respect to such matters.

any of the provisions hereof.

same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other parties, it being understood that all
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and

this Agreement shall be invalid or unenforceable in any respect, the validity
and enforceability of the remaining terms and provisions of this Agreement
shall not in any way be affected or impaired thereby and the parties will
attempt to agree upon a valid and enforceable provision which shall be a
reasonable substitute therefor, and upon so agreeing, shall incorporate such
substitute provision in this Agreement.

equal to (i) the lesser of (a) the purchase price paid by the Debtor for the
Zama Property Collateral and (b) the value of the Zama Property Collateral set
forth on the Financial Statements, less (ii) the amount of the obligations
secured by the first lien on the Zama Property Collateral. The Secured Parties

necessary to continue its business as it may be conducted and shall

Subsidiaries shall at all times maintain the liens and security interests
provided for in this Security Agreement and in the Cash Collateral Agreement as
valid and perfected liens and security interests in the Asset Collateral and the
Cash Collateral, and agrees to defend the same against any and all persons
whatsoever. Each of the Debtor and each of its Subsidiaries shall safeguard and
protect all Asset Collateral for the account of the Secured Parties and shall
not attempt to sell, assign, transfer, exchange or otherwise dispose of, or

Asset Collateral, or any interest therein, except in the ordinary course of its
business and as permitted under this Security Agreement. At the request of a
Secured Party, the Debtor or any of the Subsidiaries will sign and deliver to
such Secured Party at any time or from time to time one or more further

deemed by such Secured Party to be, necessary or desirable; each of the Debtor
and each of the Subsidiaries hereby irrevocably appoints each Secured Party as

promises to pay each Secured Party all reasonable fees and expenses incurred in
filing such Financing Statements, which fees and expenses shall become a part of
the Obligations. A carbon, photographic or other reproduction of this Agreement
or of any Financing Statement shall be sufficient as a Financing Statement. A
Secured Party shall deliver a copy of any such Financing Statement to the Debtor
and the Subsidiaries, as applicable, within three Business Days after the first

Statement in any jurisdiction.

          (c) Performance of Obligations. The Debtor shall perform all of its
obligations under the Purchase Agreement in accordance with the terms thereof,
and each of the Debtor and each of the Subsidiaries shall perform all of its
promises and covenants set forth in this Security Agreement and the Cash
Collateral Agreement in accordance with the terms hereof and thereof,
respectively.

          (d) Notice of Default, Litigation. Debtor shall promptly give notice
in writing to the Secured Parties of the occurrence of any Event of Default (as
hereinafter defined) or any material default or the occurrence of any material

effect upon the financial condition, business or normal





                                      -4-
<PAGE>   5

operations of the Debtor or any of the Subsidiaries, or any adverse effect on
the Asset Collateral.

          (e) Certificate. Debtor shall on the Closing Date and at least five
Business Days prior to any change in the make up of the Collateral deliver to
the Secured Parties a certificate executed by an executive officer of the Debtor
which describes the substituting and replaced Collateral and sets forth a list
of the Collateral and the value thereof giving effect to such change, including,
if applicable, schedule of the value of any Collateral to be purchased with the
withdrawn Cash Collateral. Such certificate shall also state that the Debtor and
the Subsidiaries are, and will be following such replacement, in compliance with
the terms of this Security Agreement and the Cash Collateral Agreement.

          (f) Consents. No consent of any other party and no consent, license,
approval or authorization of, exemption by, or registration or declaration with,
any governmental instrumentality is required to be obtained in connection with
the execution, delivery or performance of this Security Agreement.

Collateral Agreement for ten days after written notice thereof has been given to
the applicable Debtor or Subsidiary, by any Secured Party, provided that if the
default under this subparagraph 6(d) can reasonably be cured but not within ten

                                      -5-
<PAGE>   6

          (e) any representation, warranty, certification or statement made by

secured and in effect for a period of 30 days;

          (g) any material adverse change in the condition or affairs (financial
or otherwise) of the Debtor or any Subsidiary that in any Secured Party's
reasonable opinion materially decreases the Debtor or any Subsidiaries ability
to timely perform its obligations under this Security Agreement or the Cash
Collateral Agreement; and

          (h) the value of the Asset Collateral shall have, for a period of five
(5) consecutive days fallen below the Required Value as determined under Section
4 hereof.

          If one or more Event of Default shall have occurred and be continuing,
then the Debtor shall give immediate notice to each Secured Party of the
happening of such Event of Default.

     7. Remedies. (a) If an Event of Default shall have occurred and be
continuing for a period of five business days, then the Secured Parties may at
any time thereafter, without demand of performance or other demand,
advertisement or notice of any kind (all of which demands, advertisements and/or
notices are hereby expressly waived), apply the Asset Collateral to the payment
of the Obligations in such manner as the Secured Parties in their sole
discretion shall determine and the Secured Parties may sell all or any portion
of the Asset Collateral. The Secured Parties shall have no responsibility for
any loss of value of the Asset Collateral resulting from the timing of any such
sale, or otherwise.

          (b) In addition to the rights, powers and remedies granted to it in
this Security Agreement, and in any other instrument or agreement, including,
without limitation, the Purchase Agreement, the Debentures, the Cash Collateral
Agreement, or otherwise, securing, evidencing or relating to any of the
Obligations, the Secured Parties shall have all of the rights, powers and
remedies now or hereafter permitted in law or equity, including, without
limitation, those of a secured party under the Code, all such rights and
remedies being cumulative, not exclusive and enforceable alternatively,
successively or concurrently, at such time or times as the Secured Parties
thinks expedient, such remedies to be exercised only after the occurrence and
continuance of an Event of Default.

     8. Term of Agreement. This Security Agreement shall terminate when all
payments under the Debentures have been made in full and all other Obligations
have been paid or discharged. Upon such termination, each Secured Party, at the
request of Debtor, will join

<PAGE>   7

in executing any termination statement with respect to any financing statement
executed and filed pursuant to Section 5 of this Security Agreement.

     9. Expenses. Debtor agrees to reimburse each Secured Party for any and all
expenses (including reasonable attorneys' fees) incurred in enforcing any and
all of Debtor's obligations hereunder.

     10. Notice. Any and all payments, notices, requests, demands, consents,
approvals or other communications required or permitted to be given under any
provision of this Security Agreement shall be in writing and shall be deemed to
have been duly given when (i) delivered by hand, (ii) sent by telecopier,
provided that a copy is mailed by registered or certified mail, return receipt
requested, postage prepaid, or (iii) sent by Express Mail, Federal Express or
other express delivery service (receipt requested) addressed as set forth in the
Purchase Agreement. Notices to any Subsidiary shall be sent to the Debtor. Any
party may change its address for the purpose of this Security Agreement by
notice to the other party given as aforesaid.

     11. Miscellaneous.

          (a) This Security Agreement, the Cash Collateral Agreement and the
Guaranty dated the date hereof by the Subsidiaries in favor of the Secured
Parties constitute the entire agreement of the parties with respect to the
subject matter hereof and is intended to supersede all prior negotiations,
understandings and agreements with respect thereto. No provision of this
Security Agreement may be modified of amended except by a written agreement
specifically referring to this Security Agreement and signed by the parties
hereto.

          (b) In the event that any provision of this Security Agreement is held
to be invalid, prohibited or unenforceable in any jurisdiction for any reason,
unless such provision is narrowed by judicial construction, this Security
Agreement shall, as to such jurisdiction, be construed as if such invalid,
prohibited or unenforceable provision had been more narrowly drawn so as not to
be invalid, prohibited or unenforceable. If, notwithstanding the foregoing, any
provision of this Security Agreement is held to be invalid, prohibited or
unenforceable in any jurisdiction, such provision, as to such jurisdiction,
shall be ineffective to the extent of such invalidity, prohibition or
unenforceability without invalidating the remaining portion of such provision or
the other provisions of this Security Agreement and without the validity or
enforceability of such provision or the other provisions of this Security
Agreement in any other jurisdiction.

          (c) No waiver of any breach or default or any right under this
Security Agreement shall be considered valid unless in writing and signed by the
party giving such waiver, and no such waiver shall be deemed a waiver of any
subsequent breach or default or right, whether of the same or similar nature or
otherwise.

in accordance with, the laws of the State of Texas.

          (g) This Security Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. In the event that any
signature is delivered by facsimile transmission, such signature shall create a
valid binding obligation of the party executing (or on whose behalf such
signature is executed) the same with the same force and effect as if such
facsimile signature were the original thereof.

         3.      General Authority of the Collateral Agent over the Cash

         Agreement; and

                 (3)      if the Collateral Agent has been notified by any

         4.      Establishment and Maintenance of the Collateral Account.

                 (a)      The Secured Parties, the Debtor and the Subsidiaries

         5.      Reduction in Amount of Cash Collateral. The Secured Parties
hereby agree to allow the Debtor and the Subsidiaries, from time to time as

the Collateral Agent and the Secured Parties, reduce the amount of Cash
Collateral held with the Collateral Agent by withdrawing such amount from the
Cash Collateral Account, subject to the satisfaction of the following
conditions, at the time of making each withdrawal:

                 (a)      the Secured Parties shall have received from the
         Debtor and the Subsidiaries at least five (5) business days prior to
         the date of the proposed withdrawal: (A) a copy of the written request
         for withdrawal provided to the Collateral Agent by the Debtor and the
         Subsidiaries in the form attached hereto and made a part hereof as
         Exhibit A; (B) a certificate of each of the Debtor and each of the
         Subsidiaries, signed by an authorized executive officer, certifying
         that (i) the representations and warranties set forth in Section 2 of
         the Security Agreement and Section 9 of this Agreement are true and
         correct as of the date of the proposed withdrawal, (ii) as of the date
         of the proposed withdrawal, there exists no Event of Default or
         condition which would, with the giving of notice or the passage of
         time or both, if not cured, constitute an Event of Default, and (iii)
         prior to, on and immediately after the proposed withdrawal the
         Obligations will be secured in accordance this Agreement and the
         Security Agreement and at all such times the Asset Collateral shall be
         equal to or greater than the Required Value; and (C) the certificate
         required pursuant to Section 5(d) of the Security Agreement;

                 (b)      there exists no Event of Default or condition which
         would, with the giving of notice or the passage of time or both, if
         not cured, constitute an Event of Default;

                 (c)      The representations and warranties of the Debtor and
         the Subsidiaries shall contained in this Agreement and the Security
         Agreement shall be true and correct as of the date of each withdrawal;

                 (d)      There shall be no pending or threatened lawsuits or
         claims against the Debtor or any Subsidiary which, in the reasonable
         opinion of Secured Parties, would impair the credit of the Debtor any
         Subsidiary or its ability to fulfill its Obligations; and

                 (e)      There shall have been no material adverse change in
         the financial or business condition of the Debtor or any Subsidiary as
         determined by any Secured Party in its sole discretion.

If the Collateral Agent shall not have received any notice from any Secured
Party objecting to such withdrawal, then the Collateral Agent may assume that
the above conditions have been satisfied by the Debtor and the Subsidiaries. If
any Secured Party shall notify the Collateral



                                     -4-
<PAGE>   5
Agent that it objects to any such proposed withdrawal, the Collateral Agent
shall not permit such withdrawal.  Notwithstanding the obligation of the Debtor
and the Subsidiaries to notify the Secured Parties of any proposed withdrawal,
if the Collateral Agent receives any notice of withdrawal from the Debtor or
any of the Subsidiaries pursuant to this Section 5, it shall, within one
business day of its receipt of such notice, give written notice to the Secured
Parties of its receipt of such notice and deliver such notice to the Secured
Parties.

         6.      Remedies.   (a)  If an Event of Default shall have occurred 
and be continuing for a period of five business days following the notification
of the Debtor and the Subsidiaries of such Event of Default by any Secured
Party, then Secured Parties owning 2/3rds of the dollar value of the
outstanding Debentures may at any time thereafter, without demand of
performance or other demand, advertisement or notice of any kind (all of which
demands, advertisements and/or notices are hereby expressly waived), apply the
Cash Collateral to the payment of the Obligations, in such manner as such
Secured Parties in their sole discretion shall determine, provided that such
payment of the Obligations shall be made pro rata among all of the Secured
Parties, and such Secured Parties may sell all or any portion of the
instruments and securities constituting part of the Cash Collateral. The
Secured Parties shall have no responsibility for any loss of value of the Cash
Collateral resulting from the timing of any such sale, or otherwise.

                 (b)      In addition to the rights, powers and remedies
granted to it in this Agreement, and in any other instrument or agreement,
including, without limitation, the Purchase Agreement, the Debentures, the
Security Agreement, or otherwise, securing, evidencing or relating to any of
the Obligations, the Secured Parties shall have all of the rights, powers and
remedies now or hereafter permitted in law or equity, including, without
limitation, those of a secured party under the Code, all such rights and
remedies being cumulative, not exclusive and enforceable alternatively,
successively or concurrently, at such time or times as the Secured Parties
thinks expedient, such remedies to be exercised only after the occurrence and
continuance of an Event of Default.

         7.      Duty as to Cash Collateral; Liability of Collateral Agent and
Secured Party.  (a) Beyond the use of reasonable due care in the custody of the
Cash Collateral, neither the Secured Parties nor the Collateral Agent shall be
deemed to assume any responsibility for or obligation or duty with respect to
any part or all of the Cash Collateral, of any nature or kind or any matter or
proceedings arising out of or relating thereto, but the same shall be at the
sole risk at all times of the Debtor and the Subsidiaries, and without limiting
the generality of the foregoing, neither the Secured Parties nor the Collateral
Agent shall have any obligation, responsibility or liability for any loss
resulting from a fluctuation in interest rates. The Secured Parties shall not
be required to take any action of any kind to preserve or protect its or the
Debtor's or the Subsidiaries' rights in the Cash Collateral or against other
parties with respect thereto. Neither the Secured Parties nor the Collateral
Agent or any of their directors, officers, employees or agents shall be liable
for failure to demand, collect or realize upon any of the Cash Collateral or
for any delay in doing so or shall be under any obligation to sell or otherwise
dispose of any Cash Collateral upon the request of the Debtor or the
Subsidiaries or otherwise.



                                     -5-
<PAGE>   6
The Debtor and the Subsidiaries jointly and severally hereby release the
Secured Parties and the Collateral Agent from any claims, causes of action and
demands at any time arising out of or with respect to this Agreement, the use
of the Cash Collateral and/or any actions taken or omitted to be taken by the
Secured Parties with respect thereto, except to the extent caused by the gross
negligence or willful misconduct of the Secured Parties, and the Debtor and the
Subsidiaries jointly and severally hereby agree to hold the Secured Parties and
the Collateral Agent harmless from and with respect to any and all such claims,
causes of action and demands. The Secured Parties' prior recourse to any part
or all of the Cash Collateral shall not constitute a condition of any demand,
suit or proceeding for payment or collection of the Obligations. Neither the
Secured Parties nor the Collateral Agent shall have any responsibility for the
genuineness or validity of any document or other item deposited with them.

                 (b)      Notwithstanding anything to the contrary contained in
this Agreement or the Security Agreement, the Debtor and the Subsidiaries
covenant and agree, at their sole cost and expense and without cost or expense
to the Secured Parties or the Collateral Agent, to pay, protect, indemnify,
defend (with counsel acceptable to the Secured Parties and the Collateral
Agent) and hold harmless the Secured Parties and the Collateral Agent from and
against any and all reasonable expenses, damages, claims, losses, liabilities,
obligations, penalties, fines, forfeitures, contests, actions, litigation,
orders, directives, demands, defenses, judgments, suits, proceedings,
settlement orders, costs, disbursements and reasonable expenses and all other
matters of like import (including, without limitation, reasonable attorneys'
fees and expenses) of any kind and nature whatsoever which may at any time be
imposed upon, incurred by or asserted against the Secured Parties or the
Collateral Agent and which arise out of the execution, delivery, observance and
performance of this Agreement.

                 (c)      The provisions of this Section 7 shall survive the
termination for any reason of this Agreement.

         8.      No Release, Waivers, etc. (a) The Secured Parties shall not by
any act, delay, indulgence, omission or otherwise be deemed to have waived any
of their rights, powers or remedies hereunder or to have acquiesced in any
Event of Default or any breach hereof. No waiver of any right, power or remedy
hereunder on any one occasion shall be construed as a bar to any right, power
or remedy which the Secured Parties would otherwise have on any future
occasion.  No failure to exercise or any delay in exercising, on the part of
the Secured Parties, any right, power or remedy hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power or
remedy hereunder preclude any other or further exercise thereof or the exercise
of any other right, power or remedy.

                 (b)      Anything in this Agreement to the contrary
notwithstanding, (i) the Debtor and the Subsidiaries shall remain liable under
the Security Agreement to the extent set forth therein to perform all of the
Obligations to the same extent as if this Agreement had not been executed, and
(ii) the exercise by the Secured Parties of any of their rights hereunder shall
not release each of the Debtor and each of the Subsidiaries from its
Obligations under the Security



                                     -6-
<PAGE>   7
Agreement, nor shall it constitute an election of remedies by the Secured
Parties or a waiver by the Secured Parties of any of their rights and remedies
under the Security Agreement.

                 9.       Representations, Warranties and Covenants. Each of
the Debtor and the Subsidiaries hereby represent, warrant and covenant that:

                 (a)      the Security Agreement and this Agreement are
         effective to create a valid lien on and security interest of the first
         priority in the funds on deposit in the Cash Collateral Account, and
         the Debtor and the Subsidiaries have taken no action which would
         subject such funds to any prior lien or security interest or to any
         agreement purporting to grant to any third party a lien or security
         interest on the property or assets of the Debtor or the Subsidiaries
         which would include such funds, and upon the making of deposits in the
         Cash Collateral Account, all action necessary or desirable to protect
         and perfect such lien and security interest will have been duly taken;

                 (b)      no security agreements have been executed and
         delivered by the Debtor or the Subsidiaries, and no financing
         statements have been filed by them in any jurisdiction, granting or
         purporting to grant a lien on or security interest in the funds
         constituting or to constitute the Cash Collateral to any secured party
         except in connection with this Agreement and the Security Agreement;

                 (c)      no consent of any other party and no consent,
         license, approval or authorization of, exemption by, or registration
         or declaration with, any governmental instrumentality is required to
         be obtained in connection with the execution, delivery or performance
         of this Agreement;

                 (d)      it will, if an Event of Default has occurred and is
         continuing, defend the Secured Parties' right, title and interest in
         and to the Cash Collateral and the income, distributions and Proceeds
         thereof against the claims and demands of all persons and entities
         whatsoever; and

                 (e)      it shall not attempt to sell, assign, transfer,
         exchange or otherwise dispose of, or grant any option with respect to,
         the Cash Collateral, nor will it create, incur or permit to exist any
         pledge, lien, mortgage, hypothecation, security interest, charge,
         option or any other encumbrance with respect to any of the Cash
         Collateral, or any interest therein, except as permitted under this
         Agreement and the Security Agreement.

                 10.      Reimbursement of the Secured Parties. The Debtor and 
the Subsidiaries agree to promptly reimburse the Secured Parties and the
Collateral Agent for their actual out-of-pocket expenses, including, without

to any collateral agent mutually agreeable to the parties hereto, and, if no
such collateral agent shall be selected within three days of the Collateral
Agent's notification to the parties hereto of its desire to so relinquish

the Collateral Agent shall be discharged from any and all responsibility or
liability with respect to the Cash Collateral and Debtor shall promptly pay to
the Collateral Agent all monies which may be owed it for its services

         "Registrable Securities" means the shares of Common Stock issuable
upon (a) conversion in full of the Debentures, (b) exercise in full of the
Warrants and (c) payment of interest in respect of the Debentures; provided

Common Stock that are issuable upon conversion of Debentures is determined in

upon exercise in full of the maximum number of Warrants which could be issued
upon conversion of the Debentures outstanding on either the Closing Date or the
Filing Date, whichever yields a higher number of shares of Common Stock. The
Company shall be required to file additional Registration Statements to the
extent the actual number of shares of Common Stock into which Debentures are
convertible (together with interest thereon) and Warrants are exercisable
exceeds the number of shares of Common Stock initially registered in accordance
with the immediately prior sentence. The Company shall have 15 Business Days to
file such additional Registration Statement after notice of the requirement
thereof, which the Holders may give at such time when the number of shares of
Common Stock as are issuable upon conversion of Debentures exceeds 185% of the
number of shares of Common Stock into which Debentures are convertible,
assuming such conversion occurred on the Closing Date or the Filing Date
(whichever yields a lower Conversion Price.)

         "Registration Statement" means the registration statement contemplated
by Section 2(a) (covering such number of Registrable Securities and any
additional Registration Statements contemplated in the definition of
Registrable Securities), including (in each case) the Prospectus, amendments and
supplements to such registration statement or Prospectus, including pre- and
post-effective amendments, all exhibits thereto, and all material incorporated
by reference or deemed to be incorporated by reference in such registration
statement.

         "Rule 158" means Rule 158 promulgated by the Commission pursuant to
the Securities Act, as such Rule may be amended from time to time, or any
similar rule or regulation hereafter adopted by the Commission having
substantially the same effect as such Rule.

registration in connection with which securities of the Company are sold to an
underwriter for reoffering to the public pursuant to an effective registration
statement.

         2.      Shelf Registration

         (a)     On or prior to the Filing Date the Company shall prepare and
file with the Commission a Registration Statement covering all Registrable
Securities. The Registration Statement shall initially be on Form SB-2 (or, if
the Company is not permitted to register the resale of the Registrable
Securities on Form SB-2, the Registration Statement shall be on such other
appropriate form in accordance herewith as the Holders of a majority in
interest of the Registrable Securities may consent). The Company shall file a
"shelf" Registration Statement on Form S-3, for an offering to be made on a
continuous basis pursuant to Rule 415, within five Trading Days of becoming
eligible to use such form, which Registration Statement shall cover all
Registrable Securities that are unsold on the date the Company becomes so
eligible. At any time when the Company is eligible to use Form S-3, its
obligations under this Section 2(a) shall be met only by the use of such form.
The Company shall use its best efforts to cause the Registration Statement to
be declared effective under the Securities Act as promptly as possible after
the filing thereof, but in any event prior to the Effectiveness Date, and shall
file such post-effective amendments as may be required, and otherwise use its
best efforts to keep such Registration Statement continuously effective under
the Securities Act until the date which is three years after the date that such
Registration Statement is declared effective by the Commission or such earlier
date when all Registrable Securities covered by such Registration Statement
have been sold or may be sold without volume restrictions pursuant to Rule
144(k) promulgated under the Securities Act, as determined by the counsel to
the Company pursuant to a written opinion letter to such effect, addressed and
acceptable to the Company's transfer agent (the "Effectiveness Period");
provided, however, that the Company shall not be deemed to have used its best
efforts to keep the Registration Statement effective during the Effectiveness
Period if it voluntarily takes any action that would result in the Holders not
being able to sell the Registrable Securities covered by such Registration
Statement during the Effectiveness Period, unless such action is required under
applicable law or the Company has filed a post-effective amendment to the
Registration Statement and the Commission has not declared it effective.

                                      -4-
<PAGE>   5
         (b)     If the Holders of a majority of the Registrable Securities so
elect, an offering of Registrable Securities pursuant to the Registration
Statement may be effected in the form of an Underwritten Offering. In such
event, and if the managing underwriters advise the Company and such Holders in
writing that in their opinion the amount of Registrable Securities proposed to
be sold in such Underwritten Offering exceeds the amount of Registrable
Securities which can be sold in such Underwritten Offering, there shall be
included in such Underwritten Offering the amount of such Registrable
Securities which in the opinion of such managing underwriters can be sold, and
such amount shall be allocated pro rata among the Holders proposing to sell
Registrable Securities in such Underwritten Offering.

         (c)     If any of the Registrable Securities are to be sold in an
Underwritten Offering, the investment banker in interest that will administer
the offering will be selected by the Holders of a majority of the Registrable
Securities included in such offering upon consultation with the Company. No
Holder may participate in any Underwritten Offering hereunder unless such
Person (i) agrees to sell its Registrable Securities on the basis provided in
any underwriting agreements approved by the Persons entitled hereunder to
approve such arrangements and (ii) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such arrangements.

         3.      Registration Procedures

                 In connection with the Company's registration obligations
hereunder, the Company shall:

         (a)     Prepare and file with the Commission on or prior to the Filing
Date, a Registration Statement (and any additional Registration Statements as
may be required) in accordance with Section 2(a), and cause the Registration
Statement to become effective and remain effective as provided herein;
provided, however, that not less than five (5) Business Days prior to the
filing of the Registration Statement or any related Prospectus or any amendment
or supplement thereto (including any document that would be incorporated or
deemed to be incorporated therein by reference), the Company shall (i) furnish
to the Holders, their Special Counsel and any managing underwriters, copies of
all such documents proposed to be filed, which documents (other than those
incorporated or deemed to be incorporated by reference) will be subject to the
review of such Holders, their Special Counsel and such managing underwriters,
and (ii) cause its officers and directors, counsel and independent certified
public accountants to respond to such inquiries as shall be necessary, in the
opinion of respective counsel to such Holders and such underwriters, to conduct
a reasonable investigation within the meaning of the Securities Act. The
Company shall not file the Registration Statement or any such Prospectus or any
amendments or supplements thereto to which the Holders of a majority of the
Registrable Securities, their Special Counsel, or any managing underwriters,
shall reasonably object on a timely basis.

                                      -5-
<PAGE>   6
                 (b)      (i) Prepare and file with the Commission such
amendments, including post-effective amendments, to the Registration Statement
as may be necessary to keep the Registration Statement continuously effective
as to the applicable Registrable Securities for the Effectiveness Period and
prepare and file with the Commission such additional Registration Statements in
order to register for resale under the Securities Act all of the Registrable
Securities; (ii) cause the related Prospectus to be amended or supplemented by
any required Prospectus supplement, and as so supplemented or amended to be
filed pursuant to Rule 424 (or any similar provisions then in force)
promulgated under the Securities Act; (iii) respond as promptly as practicable
to any comments received from the Commission with respect to the Registration
Statement or any amendment thereto and promptly provide the Holders true and
complete copies of all correspondence from and to the Commission relating to
the Registration Statement; and (iv) comply with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in
such Prospectus as so supplemented.

                 (c)      Notify the Holders of Registrable Securities to be
sold, their Special Counsel and any managing underwriters immediately (and, in
the case of (i)(A) below, not less than five (5) days prior to such filing) and
(if requested by any such Person) confirm such notice in writing no later than
one (1) Business Day following the day (i)(A) when a Prospectus or any
Prospectus supplement or post-effective amendment to the Registration Statement
is proposed to be filed; (B) when the Commission notifies the Company whether
there will be a "review" of such Registration Statement and whenever the
Commission comments in writing on such Registration Statement (the Company
shall provide true and complete copies thereof and all written responses
thereto to each of the Holders) and (C) with respect to the Registration
Statement or any post-effective amendment, when the same has become effective;
(ii) of any request by the Commission or any other Federal or state
governmental authority for amendments or supplements to the Registration
Statement or Prospectus or for additional information; (iii) of the issuance by
the Commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings for that purpose; (iv) if at any time any of the
representations and warranties of the Company contained in any agreement
(including any underwriting agreement) contemplated hereby ceases to be true
and correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect
or that requires any revisions to the Registration Statement, Prospectus or
other documents so that, in the case of the Registration Statement or the
Prospectus, as the case may be, it will not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or

                                      -6-
<PAGE>   7
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

                 (d)      Use its best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of (i) any order suspending the effectiveness of
the Registration Statement or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

                 (e)      If requested by any managing underwriter or the
Holders of a majority in interest of the Registrable Securities to be sold in
connection with an Underwritten Offering, (i) promptly incorporate in a
Prospectus supplement or post-effective amendment to the Registration Statement
such information as such managing underwriters and such Holders reasonably
agree should be included therein and (ii) make all required filings of such
Prospectus supplement or such post-effective amendment as soon as practicable
after the Company has received notification of the matters to be incorporated
in such Prospectus supplement or post-effective amendment; provided, however,
that the Company shall not be required to take any action pursuant to this
Section 3(e) that would, in the opinion of counsel for the Company, violate
applicable law or be materially detrimental to the business prospects of the
Company.

                 (f)      Furnish to each Holder, their Special Counsel and any
managing underwriters, without charge, at least one conformed copy of each
Registration Statement and each amendment thereto, including financial
statements and schedules, all documents incorporated or deemed to be
incorporated therein by reference, and all exhibits to the extent reasonably
requested by such Person (including those previously furnished or incorporated
by reference) promptly after the filing of such documents with the Commission.

                 (g)      Promptly deliver to each Holder, their Special
Counsel, and any underwriters, without charge, as many copies of the Prospectus
or Prospectuses (including each form of prospectus) and each amendment or
supplement thereto as such Persons may reasonably request; and the Company
hereby consents to the use of such Prospectus and each amendment or supplement
thereto by each of the selling Holders and any underwriters in connection with
the offering and sale of the Registrable Securities covered by such Prospectus
and any amendment or supplement thereto.

                 (h)      Prior to any public offering of Registrable
Securities, use its best efforts to register or qualify or cooperate with the
selling Holders, any underwriters and their Special Counsel in connection with
the registration or qualification (or exemption from such registration or
qualification) of such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions as any Holder or underwriter
requests in writing, to keep each such registration or qualification (or
exemption therefrom) effective during the Effectiveness Period and to do any
and all other acts or things necessary or advisable to enable the disposition
in such jurisdictions of the Registrable Securities covered by a Registration
Statement; provided, however, that the Company shall not be required to

                                      -7-
<PAGE>   8
qualify generally to do business in any jurisdiction where it is not then so
qualified or to take any action that would subject it to general service of
process in any such jurisdiction where it is not then so subject or subject the
Company to any material tax in any such jurisdiction where it is not then so
subject.

         (i)     Cooperate with the Holders and any managing underwriters to
facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be sold pursuant to a Registration Statement, which
certificates shall be free of all restrictive legends, and to enable such
Registrable Securities to be in such denominations and registered in such names
as any such managing underwriters or Holders may request at least three
Business Days prior to any sale of Registrable Securities.

         (j)      Upon the occurrence of any event contemplated by Section
3(c)(vi), as promptly as practicable, prepare a supplement or amendment,
including a post-effective amendment, to the Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, neither the Registration Statement nor such
Prospectus will contain an untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

         (k)     Use its best efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on the American Stock
Exchange ("AMEX") and any other securities exchange, quotation system, market
or over-the-counter bulletin board, if any, on which similar securities issued
by the Company are then listed as and when required pursuant to the Purchase
Agreement.

         (l)     In the case of an Underwritten Offering, enter into such 
agreements (including an underwriting agreement in form, scope and substance as
is customary in Underwritten Offerings) and take all such other actions in
connection therewith (including those reasonably requested by any managing
underwriters and the Holders of a majority of the Registrable Securities being
sold) in order to expedite or facilitate the disposition of such Registrable
Securities, and whether or not an underwriting agreement is entered into, (i)
make such representations and warranties to such Holders and such underwriters
as are customarily made by issuers to underwriters in underwritten public
offerings, and confirm the same if and when requested; (ii) obtain and deliver
copies thereof to each Holder and the managing underwriters, if any, of
opinions of counsel to the Company and updates thereof addressed to each
selling Holder and each such underwriter, in form, scope and substance

to the selling Holders covering the matters customarily covered in opinions
requested in Underwritten Offerings and such other matters as may be reasonably
requested by such Special Counsel and underwriters; (iii) immediately prior to
the effectiveness of the Registration Statement or at the time of delivery of
any Registrable Securities sold pursuant thereto, obtain and deliver copies to
the Holders and the managing underwriters, if any, of "cold comfort" letters
and

                                      -8-
<PAGE>   9
updates thereof from the independent certified public accountants of the
Company (and, if necessary, any other independent certified public accountants
of any subsidiary of the Company or of any business acquired by the Company for
which financial statements and financial data is, or is required to be,
included in the Registration Statement), addressed to each Person and in such
form and substance as are customary in connection with Underwritten Offerings;
(iv) if an underwriting agreement is entered into, the same shall contain
indemnification provisions and procedures no less favorable to the selling
Holders and the underwriters, if any, than those set forth in Section 7 (or
such other provisions and procedures acceptable to the managing underwriters,
if any, and holders of a majority of Registrable Securities participating in
such Underwritten Offering); and (v) deliver such documents and certificates as
may be reasonably requested by the Holders of a majority of the Registrable
Securities being sold, their Special Counsel and any managing underwriters to
evidence the continued validity of the representations and warranties made
pursuant to clause 3(l)(i) above and to evidence compliance with any customary
conditions contained in the underwriting agreement or other agreement entered
into by the Company.

         (m)     Make available for inspection by the selling Holders, a
representative of such Holders, an underwriter participating in any disposition
of Registrable Securities, and an attorney or accountant retained by such
selling Holders or underwriters, at the offices where normally kept, during
reasonable business hours, all financial and other records, pertinent corporate
documents and properties of the Company and its subsidiaries, and cause the
officers, directors, agents and employees of the Company and its subsidiaries
to supply all information in each case requested by any such Holder,
representative, underwriter, attorney or accountant in connection with the
Registration Statement; provided, however, that any information that is
determined in good faith by the Company in writing to be of a confidential
nature at the time of delivery of such information shall be kept confidential
by such Persons, unless (i) disclosure of such information is required by court
or administrative order or is necessary to respond to inquiries of regulatory
authorities; (ii) disclosure of such information, in the opinion of counsel to
such Person, is required by law; (iii) such information becomes generally
available to the public other than as a result of a disclosure or failure to
safeguard by such person; or (iv) such information becomes available to such
person from a source other than the Company and such source is not known by
such Person to be bound by a confidentiality agreement with the Company.

         (n)     Comply with all applicable rules and regulations of the
Commission and make generally available to its security holders earning
statements satisfying the provisions of Section 11(a) of the Securities Act and
Rule 158 not later than 45 days after the end of any 12-month period (or 90
days after the end of any 12-month period if such period is a fiscal year) (i)
commencing at the end of any fiscal quarter in which Registrable Securities are
sold to underwriters in a firm commitment or best efforts Underwritten Offering
and (ii) if not sold to underwriters in such an offering, commencing on the
first day of the first fiscal quarter of the Company after the effective date
of the Registration Statement, which statement shall cover said 12-month
period, or such shorter period as is consistent with the requirements of Rule
158.

                                      -9-
<PAGE>   10
         (o)     The Company may require each selling Holder to furnish to the
Company such information regarding the distribution of such Registrable
Securities and the beneficial ownership of Common Stock held by such selling
Holder as is required by law to be disclosed in the Registration Statement and
the Company may exclude from such registration the Registrable Securities of
any such Holder who unreasonably fails to furnish such information within a
reasonable time after receiving such request.

         If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder
shall have the right to require (if such reference to such Holder by name or
otherwise is not required by the Securities Act or any similar Federal statute
then in force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

         Each Holder agrees by its acquisition of such Registrable Securities
that (i) it will not offer or sell any Registrable Securities under the
Registration Statement until it has received copies of the Prospectus as then
amended or supplemented as contemplated in Section 3(g) and notice from the
Company that such Registration Statement and any post/effective amendments
thereto have become effective contemplated by Section 3(c) and (ii) it will
comply with the prospectus delivery requirements of the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to
the Registration Statement.

         Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or
3(c)(vi), such Holder will forthwith discontinue disposition of such
Registrable Securities until such Holder's receipt of the copies of the
supplemented Prospectus and/or amended Registration Statement contemplated by
Section 3(j), or until it is advised in writing (the "Advice") by the Company
that the use of the applicable Prospectus may be resumed, and, in either case,
has received copies of any additional or supplemental filings that are
incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

4.       Registration Expenses

         (a)     All fees and expenses incident to the performance of or
compliance with this Agreement by the Company shall, except as and to the
extent specified in Section 4(b), be borne by the Company whether or not
pursuant to an Underwritten Offering and whether or not the Registration
Statement is filed or becomes effective and whether or not any Registrable
Securities are sold pursuant to the Registration Statement. The fees and
expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filing fees (including, without
limitation, fees and expenses (A) with respect to filings required to be made
with the AMEX and each other securities exchange or market on which Registrable
Securities are required hereunder to be listed and (B) in compliance with state
securities or Blue Sky laws (including, without limitation, fees and
disbursements

                                      -10-
<PAGE>   11
of counsel for the underwriters or Holders in connection with Blue Sky
qualifications of the Registrable Securities and determination of the
eligibility of the Registrable Securities for investment under the laws of such
jurisdictions as the managing underwriters, if any, or the Holders of a
majority of Registrable Securities may designate)), (ii) printing expenses
(including, without limitation, expenses of printing certificates for
Registrable Securities and of printing prospectuses if the printing of
prospectuses is requested by the managing underwriters, if any, or by the
holders of a majority of the Registrable Securities included in the
Registration Statement), (iii) fees and disbursements of counsel for the
Company and Special Counsel for the Holders, in the case of the Special
Counsel, to a maximum amount of $5,000, (iv) Securities Act liability
insurance, if the Company so desires such insurance, and (v) fees and expenses
of all other Persons retained by the Company in connection with the
consummation of the transactions contemplated by this Agreement. In addition,
the Company shall be responsible for all of its internal expenses incurred in
connection with the consummation of the transactions contemplated by this
Agreement (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit, the fees and expenses incurred in connection with the listing
of the Registrable Securities on any securities exchange as required hereunder.

         (b)     If the Holders require an Underwritten Offering pursuant to
the terms hereof, the Company shall be responsible for all costs, fees and
expenses in connection therewith, except for the fees and disbursements of the
Underwriters (including any underwriting commissions and discounts) and their
legal counsel and accountants. By way of illustration which is not intended to
diminish from the provisions of Section 4(a), the Holders shall not be
responsible for, and the Company shall be required to pay the fees or
disbursements incurred by the Company (including by its legal counsel and
accountants) in connection with, the preparation and filing of a Registration
Statement and related Prospectus for such offering, the maintenance of such
Registration Statement in accordance with the terms hereof, the listing of the
Registrable Securities in accordance with the requirements hereof, and printing
expenses incurred to comply with the requirements hereof.

5.       Indemnification

         (a)     Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents (including any underwriters
retained by such Holder in connection with the offer and sale of Registrable
Securities), brokers (including brokers who offer and sell Registrable
Securities as principal as a result of a pledge or any failure to perform under
a margin call of Common Stock), investment advisors and employees of each of
them, each Person who controls any such Holder (within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act) and the officers,
directors, agents and employees of each such controlling Person, to the fullest
extent permitted by applicable law, from and against any and all losses,
claims, damages, liabilities, costs (including, without limitation, costs of
preparation and attorneys' fees) and expenses (collectively, "Losses"), as
incurred, arising out of or relating to any untrue or alleged untrue statement
of a material fact contained in the

                                      -11-
<PAGE>   12
Registration Statement, any Prospectus or any form of prospectus or in any
amendment or supplement thereto or in any preliminary prospectus, or arising
out of or relating to any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in
the case of any Prospectus or form of prospectus or supplement thereto, in
light of the circumstances under which they were made) not misleading, except
to the extent, but only to the extent, that such untrue statements or omissions
are based solely upon information regarding such Holder furnished in writing to
the Company by or on behalf of such Holder expressly for use therein, or to the
extent that such information relates to such Holder or such Holder's proposed
method of distribution of Registrable Securities and was reviewed and expressly
approved in writing by such Holder expressly for use in the Registration
Statement, such Prospectus or such form of Prospectus or in any amendment or
supplement thereto. The Company shall notify the Holders promptly of the
institution, threat or assertion of any Proceeding of which the Company is
aware in connection with the transactions contemplated by this Agreement.

         (b)     Indemnification by Holders. Each Holder shall, severally and
not jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising solely out of or based solely upon any untrue
statement of a material fact contained in the Registration Statement, any
Prospectus, or any form of prospectus, or arising solely out of or based solely
upon any omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading to the extent, but only to the
extent, that such untrue statement or omission is contained in any information
so furnished in writing by such Holder to the Company specifically for inclusion
in the Registration Statement or such Prospectus or to the extent that such
information relates to such Holder or such Holder's proposed method of
distribution of Registrable Securities and was reviewed and expressly approved
in writing by such Holder expressly for use in the Registration Statement, such
Prospectus or such form of Prospectus. In no event shall the liability of any
selling Holder hereunder be greater in amount than the dollar amount of the net
proceeds received by such Holder upon the sale of the Registrable Securities
giving rise to such indemnification obligation.

         (c)     Conduct of Indemnification Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party promptly shall notify the
Person from whom indemnity is sought (the "Indemnifying Party") in writing, and
the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all fees and expenses incurred in connection with defense thereof;
provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant
to this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent

                                      -12-
<PAGE>   13
jurisdiction (which determination is not subject to appeal or further review)
that such failure shall have proximately and materially adversely prejudiced
the Indemnifying Party.

         An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall,
without the prior written consent of the Indemnified Party, effect any
settlement of any pending Proceeding in respect of which any Indemnified Party
is a party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability on claims that are the subject matter of
such Proceeding.

         All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent incurred in connection with investigating or
preparing to defend such Proceeding in a manner not inconsistent with this
Section) shall be paid to the Indemnified Party, as incurred, within 10
Business Days of written notice thereof to the Indemnifying Party (regardless
of whether it is ultimately determined that an Indemnified Party is not
entitled to indemnification hereunder; provided, that the Indemnifying Party
may require such Indemnified Party to undertake to reimburse all such fees and
expenses to the extent it is finally judicially determined that such
Indemnified Party is not entitled to indemnification hereunder).

         (d)     Contribution. If a claim for indemnification under Section
5(a) or 5(b) is unavailable to an Indemnified Party because of a failure or
refusal of a governmental authority to enforce such indemnification in
accordance with its terms (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Losses, in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the
actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such
Indemnifying Party and Indemnified Party shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission of
a material fact,

                                      -13-
<PAGE>   14
has been taken or made by, or relates to information supplied by, such
Indemnifying Party or Indemnified Party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a
result of any Losses shall be deemed to include, subject to the limitations set
forth in Section 5(c), any reasonable attorneys' or other reasonable fees or
expenses incurred by such party in connection with any Proceeding to the extent
such party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 5(d), the Purchasers
shall not be required to contribute, in the aggregate, any amount in excess of
the amount by which the proceeds actually received by the Purchasers from the
sale of the Registrable Securities subject to the Proceeding exceeds the amount
of any damages that the Purchasers have otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

         The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

     6.       Miscellaneous

         (a)     Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement.
The Company and each Holder agree that monetary damages would not provide
adequate compensation for any losses incurred by reason of a breach by it of
any of the provisions of this Agreement and hereby further agrees that, in the
event of any action for specific performance in respect of such breach, it
shall waive the defense that a remedy at law would be adequate.

         (b)     No Inconsistent Agreements. Except as and to the extent
specifically set forth in Schedule 6(b) attached hereto, neither the Company
nor any of its subsidiaries has, as of the date hereof, nor shall the Company
or any of its subsidiaries, on or after the date of this Agreement, enter into
any agreement with respect to its securities that is inconsistent with the
rights granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. Except as and to the extent specifically set forth in
Schedule 6(b) attached hereto, neither the Company nor any of its subsidiaries
has previously entered into any agreement granting any registration rights with
respect to any of its securities to any

                                     -14-
<PAGE>   15
Person. Without limiting the generality of the foregoing, without the written
consent of the Holders of a majority of the then outstanding Registrable
Securities, the Company shall not grant to any Person the right to request the
Company to register any securities of the Company under the Securities Act
unless the rights so granted are subject in all respects to the prior rights in
full of the Holders set forth herein, and are not otherwise in conflict or
inconsistent with the provisions of this Agreement.

         (c)     No Piggyback on Registrations. Except as and to the extent
specifically set forth in Schedule 2.1(s) to the Purchase Agreement, neither
the Company nor any of its security holders (other than the Holders in such
capacity pursuant hereto) may include securities of the Company in the
Registration Statement other than the Registrable Securities, and the Company
shall not enter into any agreement providing any such right to any of its
securityholders.

         (d)     Piggy-Back Registrations. If at any time during the
Effectiveness Period there is not an effective Registration Statement covering
all of the Registrable Securities and the Company shall determine to prepare
and file with the Commission a registration statement relating to an offering
for its own account or the account of others under the Securities Act of any of
its equity securities, other than on Form S-4 or Form S-8 (each as promulgated
under the Securities Act) or their then equivalents relating to equity
securities to be issued solely in connection with any acquisition of any entity
or business or equity securities issuable in connection with stock option or
other employee benefit plans, then the Company shall send to each holder of
Registrable Securities written notice of such determination and, if within
twenty (20) days after receipt of such notice, any such holder shall so request
in writing, the Company shall include in such registration statement all or any
part of the Registrable Securities such holder requests to be registered. No
right to registration of Registrable Securities under this Section shall be
construed to limit any registration otherwise required hereunder.

         (e)     Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of at least a majority of the then outstanding Registrable
Securities; provided, however, that, for the purposes of this sentence,
Registrable Securities that are owned, directly or indirectly, by the Company,
or an Affiliate of the Company are not deemed outstanding. Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of Holders and that
does not directly or indirectly affect the rights of other Holders may be given
by Holders of at least a majority of the Registrable Securities to which such
waiver or consent relates; provided, however, that the provisions of this
sentence may not be amended, modified, or supplemented except in accordance
with the provisions of the immediately preceding sentence.

                                      -15-
<PAGE>   16
         (f)     Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing
and shall be deemed given and effective on the earliest of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in this Section prior to 7:00 p.m. (New
York City time) on a Business Day, (ii) the Business Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in the Purchase Agreement later than 7:00
p.m. (New York City time) on any date and earlier than 11:59 p.m. (New York
City time) on such date, (iii) the Business Day following the date of mailing,
if sent by nationally recognized overnight courier service, or (iv) upon actual
receipt by the party to whom such notice is required to be given. The address
for such notices and communications shall be as set forth in the Purchase
Agreement or if not so set forth then to the address of such Holder as it
appears in the stock transfer books of the Company, or such other address as
may be designated in writing hereafter, in the same manner, by such Person.

         (g)     Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and permitted assigns of each of
the parties and shall inure to the benefit of each Holder. The Company may not
assign its rights or obligations hereunder without the prior written consent of
each Holder. Each Holder may assign its rights hereunder in the manner and to
the Persons as permitted under the Purchase Agreement.

         (h)     Assignment of Registration Rights. The rights of a Purchaser
hereunder, including the right to have the Company register for resale
Registrable Securities in accordance with the terms of this Agreement, shall be
automatically assignable by such Purchaser to any assignee or transferee of all
or a portion of the Debentures, the Warrants or Registrable Securities without
the consent of the Company if: (i) such Purchaser agrees in writing with the
transferee or assignee to assign such rights, and a copy of such agreement is
furnished to the Company within a reasonable time after such assignment, (ii)
the Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of (a) the name and address of such transferee or
assignee, and (b) the securities with respect to such registration rights are
being transferred or assigned, (iii) at or before the time the Company receives
the written notice contemplated by clause (ii) of this Section, the transferee
or assignee agrees in writing with the Company to be bound by all of the
provisions of this Agreement, and (iv) such transfer shall have been made in
accordance with the applicable requirements of the Purchase Agreement. The
rights to assignment shall apply to the Purchasers' (and to subsequent)
successors and assigns.

counterparts, each of which when so executed shall be deemed to be an original
and, all of which taken together shall constitute one and the same Agreement.

         (j)     Governing Law; Submission to Jurisdiction. This Agreement
shall be governed by and construed in accordance with the laws of the State of
New York, without regard to principles of conflicts of law. Each party hereby
irrevocably submits to the nonexclusive jurisdiction of any New York state
court sitting in the Borough of Manhattan, the state and federal courts sitting
in the City of New York or any federal court sitting in the Borough of
Manhattan in the City of New York (collectively, the "New York Courts") in
respect of any Proceeding arising out of or relating to this Agreement, and
irrevocably accepts for itself and in respect of its property, generally and
unconditionally, jurisdiction of the New York Courts. The Company irrevocably
waives to the fullest extent it may effectively do so under applicable law any
objection that it may now or hereafter have to the laying of the venue of any
such proceeding brought in any New York Court and any claim that any such
Proceeding brought in any New York Court has been brought in an inconvenient
forum. Nothing herein shall affect the right of any Holder. Each party hereby
irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by receiving a copy thereof sent
to such party at the address in effect for notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of
process and notice thereof. Nothing contained herein shall be deemed to limit
in any way any right to serve process in any manner permitted by law.

         (k)     Cumulative Remedies. The remedies provided herein are
cumulative and not exclusive of any remedies provided by law.

         (l)     Severability. If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the
parties hereto shall use their reasonable efforts to find and employ an
alternative means to achieve the same or substantially the same result as that
contemplated by such term, provision, covenant or restriction.  It is hereby
stipulated and declared to be the intention of the parties that they would
have executed the remaining terms, provisions, covenants and restrictions
without including any of such that may be hereafter declared invalid, illegal,
void or unenforceable.

         (m)     Headings. The headings in this Agreement are for convenience
of reference only and shall not limit or otherwise affect the meaning hereof.

         (n)     Shares Held by The Company and its Affiliates. Whenever the
consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its Affiliates (other than the Purchasers or transferees or successors or
assigns thereof if such Persons are deemed to be Affiliates solely by reason of
their holdings of such Registrable Securities) shall not be counted in
determining whether such consent or approval was given by the Holders of such
required percentage.

                  payable, paid, received or receivable with respect to the

                  of the Effective Date, between the Vendor and the Purchaser in
                  accordance with generally accepted accounting principles,
                  subject to the provisions of this Agreement. All costs of
                  whatever nature pertaining to work performed or goods or
                  services provided with respect to the Assets prior to the
                  Effective Date shall be borne by the Vendor, notwithstanding
                  that such costs may be payable in whole or in part after the
                  Effective Date.

              B.  Notwithstanding the provisions of Subclause 4.01A, all rentals
                  and all similar payments required to preserve any of the

                  the Vendor and the Purchaser on a per diem basis as of the
                  Effective Date.

              C.  Petroleum Substances which were produced, but not sold, as of
                  the Effective Date shall not form part of the Assets and shall
                  be credited to the Vendor.

              D.  Adjustments made pursuant to this Article shall be shared by
                  the parties comprising Vendor in accordance with the following
                  interests: Paramount 68.75% and J. Aron - 31.25%.

      4.02    Adjustments To Accounts

              A.  An interim accounting and adjustment shall be conducted for
                  Closing, based on the Vendor's and the Purchaser's good faith
                  estimate of all adjustments to be made for the transactions
                  herein pursuant to this Article, and a final accounting and
                  adjustment shall be conducted within one hundred and eighty
                  (180) days following the Closing Date. Subject to Subclauses B
                  and C of this Clause, the Parties shall not be obligated to
                  make any adjustments after such one hundred and eighty (180)
                  day period unless such adjustment has been specifically
                  requested, by notice, within such period. All adjustments
                  shall be settled by payment by the Party required to make

                                      -11-

              B.  During the one hundred and eighty (180) day period following
                  the Closing Date, the Purchaser may audit the books, records
                  and accounts of the Vendor respecting the Assets, for the
                  purpose of effecting adjustments pursuant to this Article.
                  Such audit shall be conducted upon reasonable notice to the
                  Vendor at the Vendor's offices during the Vendor's normal
                  business hours, and shall be conducted at the sole expense of
                  the Purchaser. Any claims of discrepancies disclosed by such
                  audit shall be made in writing to the Vendor within two (2)
                  months following the completion of such audit, and the Vendor
                  shall respond in writing to any claims of discrepancies within
                  six (6) months of the receipt of such claims. To the extent
                  that the Parties are unable to resolve any outstanding claims
                  of discrepancies disclosed by such audit within two (2) months
                  of the Vendor's response thereto, such audit exceptions shall
                  be resolved pursuant to Article 9.00.

              C.  Notwithstanding the preceding Subclauses of this Clause,
                  Clause 6.01, Clause 6.03 and Clause 13.01, any adjustments
                  resulting from joint venture or royalty audits for the Assets:

                  (i)  relating to the period prior to Closing Date and for
                       which audit queries are outstanding at Closing Date; or

                  (ii) that occur after Closing Date but not later than two (2)
                       years after Closing Date or for the applicable period in
                       the governing agreements included in Miscellaneous
                       Interests, whichever is later (in the case of joint
                       venture audits), or four (4) years after Closing Date (in
                       the case of Crown royalty audits);

                  shall be made as they occur and payment for them shall be made
                  within thirty (30) days of each adjustment and shall be made
                  by Purchaser to Vendor, or vice versa, as the case may be.

5.00  MAINTENANCE OF BUSINESS

      5.01    The Vendor shall continue to maintain the Assets in a proper and
              prudent manner in accordance with good oil field practice and the
              Regulations until the Closing Date.

      5.02    Prior to the Closing Date, the Vendor shall not, without the prior
              consent of the Purchaser, assume any material obligation or
              commitment or propose or initiate any operation with respect to
              the Assets where the Vendor's share of the expenditure associated
              with such obligation, commitment or operation is estimated to
              exceed $25,000, unless and to the extent that the Vendor
              reasonably determines that such expenditures or actions are
              necessary for the protection of life or property, in which case
              the Vendor shall promptly notify the Purchaser of such intention
              or actions and the Vendor's estimate of the costs and expenses
              associated therewith.

      5.03    Following Closing and to the extent that the Purchaser must be
              novated into operating agreements or other agreements governing
              any of the Assets, the Vendor shall be deemed to have been acting
              as the agent of the Purchaser until the novation has been
              effected. Insofar as the Vendor maintains the Assets and takes
              actions with respect thereto on behalf of the Purchaser pursuant
              to this Article, the Vendor shall be deemed to have been




<PAGE>   12
                                      -12-


              the agent of the Purchaser hereunder. The Purchaser ratifies all
              actions taken by the Vendor or refrained to be taken by the Vendor
              as authorized hereunder in such capacity during such period, with
              the intention that all such actions shall be deemed to be those of
              the Purchaser. In addition to the foregoing, prior to the Closing
              Date Vendor shall not, without first obtaining the prior written
              consent of the Purchaser (which consent shall not be unreasonably
              withheld), make any material amendment to any of the Leases or
              contracts applicable to the Assets, or enter into any new
              contracts applicable to the Assets, save where this would be done
              in the ordinary and usual course of business.

      5.04    The Purchaser shall indemnify the Vendor and its directors,
              officers, servants, agents or employees against all liabilities,
              losses, costs (including reasonable legal costs on a
              solicitor-client basis), claims or damages which the Vendor or its
              directors, officers, servants, agents or employees may suffer or
              incur as a result of maintaining the Assets as the agent of the
              Purchaser pursuant to this Article, insofar as such liabilities,
              losses, costs, claims or damages are not a direct result of the
              gross negligence or wilful misconduct of the Vendor or its
              directors, officers, servants, agents or employees. An action or
              omission of the Vendor or its directors, officers, servants,
              agents or employees shall not be regarded as gross negligence or
              wilful misconduct, however, to the extent it was done or omitted
              to be done in accordance with the instructions of or with the
              concurrence of the Purchaser.

      5.05    Notwithstanding anything to the contrary herein contained, if
              prior to Closing:

              (i) Vendor seeks recourse against Purchaser pursuant to Clause
                  5.04; or

              (ii) Vendor or Purchaser identify any third party unsatisfied
                  judgments, claims, proceedings, actions, investigations or
                  lawsuits in existence against Purchaser and/or contemplated or
                  threatened in writing against Purchaser,

              with respect to the Assets, with a claimed amount in excess of
              $50,000.00 and which arise out of any matter or thing occurring,
              attributable or arising during the period between and including
              the Effective Date to and including the day prior to the Closing
              Date, Purchaser may, on or before Closing, terminate this
              Agreement by written notice to Vendor without prejudice to any
              other rights of Purchaser against Vendor hereunder. The Purchaser,
              in electing to terminate the Agreement pursuant to this clause,
              must act reasonably and in good faith.

      5.06    Paramount hereby agrees that it will make necessary surface and
              mines and minerals lease rental payments on behalf of the
              Purchaser through to and including January 31st, 1998. Such
              payments will be adjusted in accordance with the provisions of
              Clause 4.02.

6.00  REPRESENTATIONS AND WARRANTIES OF PARTIES

      6.01    Vendor's Representations And Warranties

              (f) No Finders' Fees: The Purchaser shall not have any
                  responsibility for any obligation or liability, contingent or

                  Permitted Encumbrances;

              (l) No Reduction: The interests of the Vendor in the Assets are
                  not subject either to reduction, or to change to an interest
                  of any other size or nature whatsoever by virtue of any right

              (m) Sale Agreements: The Petroleum and Natural Gas Rights are not
                  subject to any gas balancing agreement or, except as

                  Petroleum Substances therefrom which the Purchaser is required
                  to assume that requires either the sale of more than thirty
                  (30) days of production (without an early termination penalty
                  or other cost) or the delivery of Petroleum Substances to the
                  purchaser thereof without receiving in due course (and being
                  entitled to retain) full payment at current market price or
                  the contract price therefor;

              (n) Environmental Matters: The Vendor is not aware of and has not

                       have not been complied with in all material respects; and

                  quantity, quality or recoverability of Petroleum Substances
                  respecting the Lands; (ii) any estimates of the value of the

                  subject always to Clause 6.03, the Purchaser acknowledges that
                  it has made its own independent investigation, analysis,
                  evaluation and inspection of the Vendor's interests in the
                  Assets and the state and condition thereof and that it has
                  relied solely on such investigation, analysis, evaluation and
                  inspection as to its assessment of the condition, quantum and
                  value of the Assets.

              B.  Except with respect to the representations and warranties in
                  Clause 6.01, the Purchaser forever releases and discharges the
                  Vendor and its directors, officers, servants, agents and
                  employees from any claims and all liability to the Purchaser
                  or the Purchaser's assigns and successors, as a result of the
                  use or reliance upon advice, information or materials
                  pertaining to the Assets which was delivered or made available
                  to the Purchaser by the Vendor or its directors, officers,
                  servants, agents or employees prior to or pursuant to this
                  Agreement, including, without limitation, any evaluations,
                  projections, reports and interpretive or non-factual materials
                  prepared by or for the Vendor, or otherwise in the Vendor's
                  possession.

                  serve all notices as are required under such preferential
                  purchase. Unless otherwise agreed by the Purchaser, each such
                  notice shall include a request for a waiver of any

                  Vendor is required to give notice pursuant to this Clause, and
                  such allocation shall be used for the purposes of this Clause
                  except where such allocations are deemed to be unreasonable by
                  the Vendor.

              C.  The Purchaser shall indemnify and save the Vendor and its
                  directors, officers, servants, agents and employees harmless
                  from and against all losses, costs, damages and expenses
                  whatsoever which the Vendor and its directors, officers,
                  servants, agents and employees may sustain, pay or incur as a
                  result of any matter or thing arising out of, resulting from,
                  attributable to or connected with the Purchaser's placement of
                  value on any of the Assets with respect to which the Vendor is
                  required to give notice pursuant to this clause.

                  Assets exercises such right, Vendor shall notify Purchaser in

              The Parties acknowledge that the consent to assignment from buyers
              under production sales agreements included in the Assets may not

              seeking such consents.

      7.03    Operatorship And Third Parties

              Nothing in this Agreement shall be interpreted as any assurance by
              the Vendor that the Purchaser will be able to serve as operator
              with respect to any of the Assets in which interests are held by
              third parties, whether or not such Assets are presently operated
              by the Vendor. Where Paramount is the operator Paramount shall,
              after Closing, recommend to third parties that the Purchaser be
              appointed operator of the Assets.

8.00  PURCHASER'S REVIEW

      8.01    Vendor To Provide Access

              The Vendor shall, subject to the Regulations and all contractual
              and fiduciary obligations and limits:

              (a) at the office of Paramount during normal business hours,
                  provide the Purchaser and its nominees reasonable access to
                  the Vendor's records, files and documents directly relating to
                  the Assets, for the purpose of the Purchaser's review of the
                  Assets and the Vendor's title thereto, including, without
                  limitation, the Leases and applicable operating agreements,
                  unit agreements, overriding royalty agreements and production
                  sale contracts; and

              (b) subject to sub-clause 10.02(f), provide the Purchaser and its
                  nominees with a reasonable opportunity to inspect the Assets
                  at the Purchaser's sole cost, risk and expense, insofar as the
                  Vendor can reasonably provide such access to the Assets.

      8.02    Title Defects

              A.  The Purchaser shall conduct its review of the Vendor's title
                  to the Assets with reasonable diligence. Not later than ten
                  (10) business days prior to the Closing Date, the Purchaser
                  shall give the Vendor written notice of the Title Defects
                  which the Purchaser does not waive. Such notice shall specify
                  such Title Defects in reasonable detail, the Assets directly
                  affected thereby and the Purchaser's requirements for the
                  rectification or curing thereof. The Vendor shall thereupon
                  diligently make reasonable efforts to cure such Title Defects
                  on or before the Closing Date.

              B.  Insofar as the Title Defects described in the Purchaser's
                  notice (the "Affected Interests") have not been cured to the
                  Purchaser's reasonable satisfaction, but subject at all times
                  to Clause 10.04 with respect to prior third party rights, the
                  Purchaser may elect, at or before the Closing Date by notice
                  to the Vendor, to do one of the following:

                                      -20-


              (a) where the cumulative amount by which the value of the Assets
                  has been reduced is, in Purchaser's opinion, acting
                  reasonably, less than Four Hundred and Seventy-Five Thousand
                  ($475,000.00) Dollars, Purchaser shall complete the purchase
                  of Vendor's interest in and to the Assets without any
                  adjustment of the Purchase Price.

              (b) where the cumulative amount by which the value of the Assets
                  has been reduced is, in Purchaser's opinion, acting
                  reasonably, equal to or greater than Four Hundred and
                  Seventy-Five Thousand ($475,000.00) Dollars, the following
                  options shall arise:

                  (i)  the Parties may delay Closing to a mutually agreeable
                       time and date during which time Vendor shall make further
                       attempts to cure or remove the uncured Title Defects. In
                       the event that said Title Defects have not been cured
                       prior to December 1, 1997, the elections set out in this
                       Paragraph 8.02B(b) shall once again be made; or

                  (ii) Purchaser may waive the uncured Title Defects, in which
                       case all of Vendor's interest in and to the Assets shall
                       be purchased by Purchaser without an adjustment to the
                       Purchase Price; or

                  (iii)Purchaser shall purchase Vendor's interest in and to the
                       Assets in which case the Purchase Price shall be adjusted
                       by an amount equal to that number arrived at by
                       subtracting $475,000.00 from the value attributed to the
                       Affected Interest by the Parties, or any arbitrator, such
                       that only positive values resulting from this calculation
                       are to be adjusted. Provided that in reaching the
                       mutually agreed upon value, the Parties, or any
                       arbitrator appointed hereunder, shall take into account
                       the probability of the Title Defect actually
                       materializing having regard to the particular
                       circumstances.

              (c) where the cumulative amount by which the value of the Assets
                  has been reduced, in Purchaser's opinion, acting reasonably,
                  by Twenty (20%) Percent or more of the Purchase Price then, in
                  addition to the elections set out in Clause 8.02B(b), either
                  Vendor or Purchaser may terminate this Agreement upon written
                  notice to the other Party, in which case Vendor shall
                  forthwith return the Deposit and accrued interest to Purchaser
                  and the Parties shall have no further obligation to each other
                  hereunder, and shall have no right to claim further damages or
                  other remedies.

         C.   If the Purchaser elects to proceed with Closing pursuant to
              Paragraph 8.02B(b)(iii) and the Parties have neither previously
              determined the portion of the Purchase Price applicable to the
              Assets directly affected by the applicable uncured Title Defects
              nor otherwise agreed upon such portion prior to the Closing Date,
              the following shall apply:

              (a) the Purchaser shall deduct from the Purchase Price an amount
                  equal to the Purchaser's good faith estimate of the portion of
                  the Purchase Price applicable to the directly affected Assets,
                  as of the Effective Date, less $475,000.00 and deposit such
                  amount with a Canadian chartered bank in an interest bearing
                  account, in trust for the purposes of this Agreement;




<PAGE>   21
                                      -21-


              (b) the Parties then shall refer the determination of the portion
                  of the Purchase Price applicable to the directly affected
                  Assets, as of the Effective Date, to an arbitrator pursuant to
                  Article 9.00, insofar as they are unable to agree on such
                  portion; and

              (c) the funds retained in trust pursuant to Paragraph (b) of this
                  Subclause and the accrued interest thereon shall be released
                  from such trust account following such determination. To the
                  extent (if any) that the Purchaser's estimate of the
                  applicable portion of the Purchase Price varies from the
                  amount determined pursuant to Paragraph (b) of this Subclause,
                  the excess or deficiency and the interest which accrued
                  thereon shall be paid by the Purchaser to the Vendor within
                  fifteen (15) days of such determination or be retained by the
                  Purchaser, as applicable.

         D.   If a portion of the Assets is excluded from the Closing pursuant
              to Article 7.00:

              (a) the terms "Assets", "Lands", "Leases", "Miscellaneous
                  Interests", "Petroleum and Natural Gas Rights" and "Tangibles"
                  shall be construed as meaning only that portion of the subject
                  matter of those terms with respect to which Closing occurs;

              (b) the Purchase Price shall be reduced by the aggregate value
                  attributed to the Assets with respect to which Closing does
                  not occur, the term "Purchase Price" shall then be construed
                  to be such reduced amount and the allocation of the Purchase
                  Price pursuant to Clause 2.02 shall be determined by agreement
                  of the Parties or by Article 9.00 and adjusted accordingly.

9.00  ARBITRATION

      9.01    Reference To Arbitration

              A.  Insofar as the Parties are unable to agree on any matter which
                  expressly may be referred to arbitration hereunder, either
                  Party may serve the other Party written notice that it wishes
                  such matter referred to arbitration.

              B.  The Parties shall meet within seven (7) days of the receipt of
                  a notice issued pursuant to Subclause 9.01A, to attempt to
                  agree on a single arbitrator qualified by experience,
                  education and training, to determine such matter. If the
                  Parties are unable to agree on the selection of the
                  arbitrator, the Party which issued such notice shall forthwith
                  make application to a judge of the Court of Queen's Bench of
                  the Province of Alberta pursuant to the Arbitration Act of the
                  Province of Alberta (S.A. 1991 c.43-1, as amended from time to
                  time, hereinafter referred to as the "Arbitration Act") for
                  the appointment of a single arbitrator, and failing such
                  action on the part of the Party which issued such notice, the
                  other Party may make such application.

      9.02    Proceeding

              A.  The arbitrator selected pursuant to Clause 9.01 shall proceed
                  as soon as is practicable to hear and determine the matter in
                  dispute, and shall be directed to

                                      -22-


              provide a written decision respecting such matter within
              forty-five (45) days of appointment. The Parties shall provide
              such assistance and information as may be reasonably necessary to
              enable the arbitrator to determine such matter.

      B.      Except to the extent modified in this Article, the arbitrator
              shall conduct any arbitration hereunder pursuant to the provisions
              of the Arbitration Act.

                  licence from the Vendor to the Purchaser may not be obtainable
                  until after Closing and that the acquisition of such consents
                  shall not be a condition precedent to Closing.

      10.02   Conditions For Benefit Of Purchaser

              The obligation of the Purchaser to complete the purchase hereunder
              is subject to the following conditions precedent:

                  alteration of any of the Assets between the Effective Date and

                  would materially and adversely affect the value of the Assets,
                  except and to the extent approved in writing by the Purchaser,
                  and the Vendor shall have delivered to the Purchaser a
                  certificate of a Vice President, Corporate Secretary or other

                  the Vendor, there has been no such damage or alteration of any
                  of the Assets during such period, provided that a change in
                  the prices at which Petroleum Substances may be sold in no
                  event shall be regarded as material damage to or an alteration
                  of the Assets;

              (b) Availability Of Documents: The Vendor shall have provided the
                  nominees of the Purchaser with reasonable access to the
                  Vendor's records and documents pertaining to the Assets

              (d) Certificate That Representations Are Correct: The Vendor shall

                  senior officer of the Vendor, in the form of Schedule "D" and

                  covenants, representations and warranties contained in Clause
                  6.01 was, as of the Effective Date, and is, as of the Closing
                  Date, true and correct in all material respects, except for
                  those changes thereto which necessarily arise as a consequence
                  of the operation of the provisions of this Agreement, as
                  specifically provided herein;

              (e) Delivery Of Conveyance Documents: The Vendor shall have

                  those other documents and materials described in Paragraphs
                  3.03 A(b), (c), (d), (e) and (f) which are to be provided to
                  the Purchaser at Closing;

              (f) Physical Review of Assets: The Vendor shall permit Purchaser
                  and its nominees to conduct an evaluation and physical review
                  of any or all of the Assets. The purpose of such review is for
                  the Purchaser to satisfy itself as to the environmental
                  condition of the Assets. If, in the reasonable opinion of the
                  Purchaser, material and adverse deficiencies are identified,
                  Purchaser may, by written notice issued on or before September
                  22, 1997, terminate this Agreement. If Purchaser elects to
                  proceed, or fails to notify Vendor of any deficiencies within
                  the time frame herein contemplate, Purchaser acknowledges that
                  the Assets shall be purchased on an 'as is, where is basis;

              (g) Transfer of Well Licences: If Purchaser obtains a written

                  Purchaser as a condition for approval of the transfer of well
                  licences to the Purchaser, which aggregate new operatorship
                  requirements include posting cash security in excess of
                  $250,000.00, then Purchase may, within five (5) business days
                  of execution of this Agreement but no later than October 30,
                  1997, elect to terminate this Agreement;

              (h) No Unidentified Preferential Right of Purchase: If the Vendor
                  has omitted to identify in Schedule "A" a preferential right
                  of purchase or similar restriction that was both material and
                  adverse taking into account the magnitude of the Lands
                  affected by the unidentified preferential right of purchase,
                  then Purchaser may, on or before Closing, terminate this
                  Agreement;

              (i) No Clause 5.05 Termination: Purchaser has not terminated this
                  Agreement in accordance with Clause 5.05; and

              (j) Contractual Arrangements: On or before Closing, Purchaser
                  shall be satisfied, acting reasonably, with the existing
                  contractual arrangements for the transportation, processing
                  and sale of the Petroleum Substances, to ensure that the terms
                  thereof are not materially adverse to the interest of the 
                  Purchaser.

10.03 Conditions For Benefit Of Vendor

      The obligation of the Vendor to complete the sale hereunder is subject to
      the following conditions precedent:

      10.04   Waiver Of Conditions

              The conditions in Clauses 10.02 and 10.03 are for the sole benefit

              operation of any preferential right of a third party to purchase
              any of the Assets.

      10.05   Failure To Satisfy Conditions

              (a) In the event any of the conditions in Clauses 10.02 or 10.03
                  has not been satisfied at or before the Closing Date and such
                  condition has not been waived by the Party for the benefit of
                  which such condition has been included, such Party may
                  terminate this Agreement by written notice to the other Party.
                  However, a Party may not terminate this Agreement in such
                  manner after Closing, and its remedies thereafter, if any,

                  the conditions contained in Clause 10.02, Vendor shall
                  forthwith return the Deposit and any accrued interest thereon
                  to Purchaser with no right to claim further damages or other
                  remedies from Vendor. Other than as outlined in Subclause
                  8.02B(c), if Vendor terminates this Agreement, Vendor shall be
                  entitled to retain the Deposit and any accrued interest

              may apply thereto following the Purchaser's acquisition of the
              Assets. Any additional information obtained as a result of such
              access which does not relate to the Assets shall continue to be

              such amount was due to be paid until the day such amount was paid,
              at the rate of two (2%) percent per annum above the Prime Rate
              regardless of whether such Party has given the other Party prior
              notice of the accrual of interest hereunder.

13.00 LIABILITY AND INDEMNIFICATION

      13.01   Responsibility Of Vendor

              Subject to Clauses 13.03 and 13.04 and provided that Closing has
              occurred, the Vendor shall:

              (a) be liable to the Purchaser for all losses, costs, damages and
                  expenses whatsoever which the Purchaser may suffer, sustain,
                  pay or incur; and

              (b) indemnify and save the Purchaser and its directors, officers,
                  servants, agents and employees harmless from and against all
                  claims, liabilities, actions, proceedings, demands, losses,
                  costs, damages and expenses whatsoever which may be brought
                  against or suffered by the Purchaser, its directors, officers,
                  servants, agents or employees or which they may sustain, pay
                  or incur;

              as a direct result of a breach as of the Closing Date of any
              warranty or representation of Vendor contained in this Agreement,
              except any losses, costs, damages, expenses, claims, liabilities,
              actions, proceedings and demands to the extent that the same
              either are reimbursed (or reimbursable) by insurance maintained by
              the Purchaser or are caused by the gross negligence or wilful
              misconduct of the Purchaser, its directors, officers, servants,
              agents, employees or assigns. The indemnity granted by the Vendor
              herein, however, is not a title warranty and does not provide
              either an extension of any representation or warranty contained in
              Clause 6.01 or an additional remedy with respect to the Vendor's
              breach of such a representation or warranty. Notwithstanding any
              provision herein, the liability of the Vendor and the indemnity
              hereby granted by the




<PAGE>   26

                                      -26-

              Vendor to the Purchaser shall only apply with respect to claims
              made within one (1) year following the Closing Date.

      13.02   Responsibility Of Purchaser

      Provided that Closing has occurred, the Purchaser shall:

              (a) be liable to the Vendor for all losses, costs, damages and
                  expenses whatsoever which the Vendor may suffer, sustain, pay
                  or incur; and

              (b) indemnify and save the Vendor and its directors, officers,
                  servants, agents and employees harmless from and against all
                  claims, liabilities, actions, proceedings, demands, losses,
                  costs, damages and expenses whatsoever which may be brought
                  against or suffered by the Vendor, its directors, officers,
                  servants, agents or employees or which they may sustain, pay
                  or incur;

              as a direct result of any matter or thing arising out of,
              resulting from, attributable to or connected with the Assets and
              occurring or attributable to the period after the Effective Date,
              except any losses, costs, damages, expenses, claims, liabilities,
              actions, proceedings and demands to the extent that the same
              either are reimbursed (or reimbursable) by insurance maintained by
              the Vendor or are caused by the gross negligence or wilful
              misconduct of the Vendor, its directors, officers, servants,
              agents, employees or assigns. Nothing in this Clause, however,
              shall operate either to limit any representation or warranty made
              by the Vendor pursuant to Clause 6.01 or to affect the Purchaser's
              right to make a claim against the Vendor for the breach of such a
              representation or warranty within a period of one (1) year
              following Closing.

      13.03   Limit On Vendor's Responsibility

              In no event shall the total of the liabilities and indemnities of
              the Vendor under this Agreement, including, without limitation,
              any claims relating to its representations and warranties, exceed
              the Purchase Price, except in the event of fraud.

      13.04   Assets Acquired On "As Is" Basis

              Notwithstanding the foregoing provisions of this Article, the
              Purchaser acknowledges that it is acquiring the Assets on an "as
              is" basis, as of the Effective Date. The Purchaser acknowledges
              that it is familiar with the condition of the Assets, including
              the past and present use of the Lands and the Tangibles, that the
              Vendor has provided the Purchaser with a reasonable opportunity to
              inspect the Assets at the sole cost, risk and expense of the
              Purchaser (insofar as the Vendor could reasonably provide such
              access) and that the Purchaser is not relying upon any
              representation or warranty of the Vendor as to the condition,
              environmental or otherwise, of the Assets, except as is
              specifically made pursuant to Clause 6.01(n). Provided that
              Closing has occurred, the Purchaser further agrees that, as of the
              Effective Date, it shall:

              (a) be solely liable and responsible for any and all losses,
                  costs, damages and expenses which the Vendor may suffer,
                  sustain, pay or incur; and

              (b) indemnify and save the Vendor and its directors, officers,
                  servants, agents and employees harmless from any and all
                  claims, liabilities, actions, proceedings,



<PAGE>   27
                                      -27-


                  demands, losses, costs, damages and expenses whatsoever which
                  may be brought against or suffered by the Vendor, its
                  directors, officers, servants, agents or employees or which
                  they may sustain, pay or incur;

              as a result of any matter or thing arising out of, resulting from,
              attributable to or connected with any environmental liabilities
              pertaining to the acquired Assets, or any of them, including,
              without limitation, damage from or removal of hazardous or toxic
              substances, clean-up, Well abandonment and reclamation. Once
              Closing has occurred, the Purchaser shall be solely responsible
              for all environmental liabilities respecting the Lands, the
              abandonment of all Wells on the Lands and the reclamation of the
              Lands as between the Vendor and the Purchaser, and hereby releases
              the Vendor from any claims the Purchaser may have against the
              Vendor with respect to all such liabilities and responsibilities.
              Nothing in this Clause, however, shall operate either to limit any
              representation or warranty made by the Vendor pursuant to Clause
              6.01(n) or to affect the Purchaser's right to make a claim
              against the Vendor for the breach of such a representation or
              warranty within a period of one (1) year following Closing.

      13.05   No Merger Of Legal Responsibilities

              The liabilities and indemnities created in this Article shall be
              deemed to apply to, and shall not merge in, all assignments,
              transfers, conveyances, novations, trust agreements and other
              documents conveying any of the Assets from the Vendor to the
              Purchaser, notwithstanding the terms of such assignments,
              transfers, conveyances, novations and other documents, the
              Regulations or any rule of law or equity to the contrary, and all
              such rules are hereby waived.

      13.06   Responsibility Extends To Legal Costs

              Notwithstanding any provision to the contrary contained in this
              Article, references to costs in the liability and indemnification
              obligations prescribed by Clauses 13.01, 13.02 and 13.04 shall be
              deemed to include reasonable legal costs on a solicitor-client
              basis.

14.00 WAIVER

      14.01   Waiver Must Be In Writing

              No waiver by any Party of any breach (whether actual or
              anticipated) of any of the terms, conditions, representations or
              warranties contained herein shall take effect or be binding upon
              that Party unless the waiver is expressed in writing under the
              authority of that Party. Any waiver so given shall extend only to
              the particular breach so waived and shall not limit or affect any
              rights with respect to any other or future breach.

15.00 ASSIGNMENT

      15.01   Assignments Before Closing

              Prior to Closing, neither Party may assign its interest in or
              under this Agreement or to the Assets without the prior written
              consent of the other Party, except as may be required by the
              Vendor to comply with its obligations respecting any preferential
              rights, as provided in Article 7.00.

      15.02   Assignments By Purchaser After Closing

              No assignment, transfer or other disposition of this Agreement or
              all or any portion of the Assets by the Purchaser after Closing
              shall relieve the Purchaser from its obligations to the Vendor
              herein. The Vendor shall have the option to claim payment or
              performance of such obligations from the Purchaser or the assignee
              or transferee, and to bring proceedings in the event of default
              against either or all of them, provided that nothing herein shall
              entitle the Vendor to receive duplicate payment or performance of
              the same obligation.

16.00 NOTICE

      16.01   Service Of Notice

              Notwithstanding anything to the contrary contained herein, all
              notices required or permitted hereunder shall be in writing. Any
              notice to be given hereunder shall be deemed to be served properly
              if served in either of the following modes:

              (a) personally, by delivering the notice to the Party on which it
                  is to be served at that Party's address for service.
                  Personally served notices shall be deemed to be received by
                  the addressee when actually delivered as aforesaid, provided
                  that such delivery shall be during normal business hours on
                  any day other than a Saturday, Sunday or statutory holiday in
                  Alberta. If a notice is not delivered on such a day or is
                  delivered after the addressee's normal business hours, such
                  notice shall be deemed to have been received by such Party at
                  the commencement of the addressee's first business day next
                  following the time of the delivery; or

              (b) by telecopier or telex (or by any other like method by which a
                  written message may be sent) directed to the Party on which it
                  is to be served at that Party's address for service. A notice
                  so served shall be deemed to be received by the addressee
                  when actually received by it, if received within normal
                  business hours on any day other than a Saturday, Sunday or
                  statutory holiday in Alberta or at the commencement of the
                  next ensuing business day following transmission if such
                  notice is not received during such normal business hours.

17.00 PUBLIC ANNOUNCEMENTS

      17.01   Parties To Discuss Press Releases

              A.  The Parties shall cooperate with each other in relaying to
                  third parties information concerning this Agreement and the
                  transactions contemplated herein, and shall discuss drafts of
                  all press releases and other releases of information for
                  dissemination to the public pertaining hereto. However,
                  nothing in this Clause shall prevent a Party from furnishing
                  any information to any governmental agency or regulatory
                  authority or to the public, insofar only as is required by the
                  Regulations or securities laws applicable to such Party,
                  provided that a Party which proposes to make such a public
                  disclosure shall, to the extent reasonably possible, provide
                  the other Party with a draft of such statement a sufficient
                  time

                  prior to its release to enable such other Party to review such
                  draft and advise that Party of any comments it may have with
                  respect thereto.

              B.  Notwithstanding Subclause 17.01A, the Vendor shall be
                  permitted to disclose information pertaining to this Agreement
                  and the identity of the Purchaser, to the extent required to
                  enable the Vendor to fulfill its obligations pertaining to
                  preferential rights of purchase and other third party rights,
                  in accordance with Article 7.00.

              Following Closing, the Vendor may remove any signs which indicate
              the Vendor's ownership or operation of the Assets. If the

              responsibility of the Purchaser to erect or install any signs
              required by governmental agencies which pertain to the Assets. In
              addition, the Purchaser shall be responsible for promptly advising
              governmental agencies, contractors, suppliers and other affected 
              third parties of the Purchaser's interest in the Assets, subject
              to Article 7.00 and Clause 10.01.

              fulfill their respective obligations under this Agreement. The
              Vendor shall cooperate with the Purchaser as reasonably required
              to secure execution by third parties of the documents referred to
              in Paragraph 3.03A(b).

      18.02   Governing Law

              written instrument executed by the Vendor and the Purchaser.

      18.05   Consequences Of Termination

              If this Agreement is terminated in accordance with its terms prior
              to Closing, then except for the provisions of Articles 11.00 and
              12.00 and the covenants, warranties, representations or other
              obligations breached prior to the time at which such termination
              occurs, the Parties shall be released from all of their

              provisions of Subclause 2.03(a). If this Agreement is so




<PAGE>   31
                                      -31-

              terminated, the Purchaser shall promptly return to the Vendor
              all materials delivered to the Purchaser by the Vendor hereunder,
              together with all copies of them that may have been made by or for
              the Purchaser.

      18.06   Supersedes Earlier Agreements

              This Agreement supersedes all other agreements between the Parties
              with respect to the Assets and expresses the entire agreement of
              the Parties with respect to the transactions contained herein.

      18.07   Enurement

              Subject to the provisions of Article 15.00, this Agreement shall
              be binding upon and enure to the benefit of the Parties and their
              respective successors and permitted assigns.

                         V. PURCHASER'S REPRESENTATIONS

                 Purchaser represents and warrants to and with Seller that:

         (a)     Purchaser is a corporation duly organized, validly existing,
and in good standing under the laws of the State of Oklahoma and Purchaser is

         (d)     Purchaser will protect, defend, and indemnify Seller from and

<PAGE>   7
         (e)     Purchaser shall not pay any commissions or fees to any
employee, officer or agent of Seller nor favor employees, officers or agents of
Seller with gifts or entertainment of significant cost or value, nor enter into
any business arrangement with employees, officers or agents of Seller other
than as representative of Seller, without Seller's written approval.


                              VI.  PROPERTY REVIEW

         (a)     Seller shall allow Purchaser access to examine title and such
documents as listed in Article XIV which relate to the Leases at Seller's office
in Houston, Texas.  Seller shall not be obligated to perform any title work and
shall not be required to update or supplement abstracts or title opinions.
PURCHASER ACKNOWLEDGES THAT SELLER HAS MADE NO REPRESENTATIONS OR WARRANTIES AS
TO THE ACCURACY OR COMPLETENESS OF SUCH INFORMATION OR AS TO ITS TITLE TO THE
ASSETS, AND IN ENTERING INTO AND PERFORMING THIS AGREEMENT, PURCHASER HAS
RELIED AND WILL RELY SOLELY UPON ITS INDEPENDENT INVESTIGATION OF AND JUDGMENT
WITH RESPECT TO THE ASSETS, THEIR VALUE, AND SELLER'S TITLE THERETO.

         (b)     Purchaser shall notify Seller in writing not later than 12:00
noon, central time, May 1, 1998, of any Title Defect which is discovered by
Purchaser.  For purposes of this Agreement, a "Title Defect" shall mean that
Seller's title (as to one or more of the Assets) is subject to an outstanding
mortgage, deed of trust, lien or encumbrance not reflected on Exhibit "A".
FAILURE TO TIMELY GIVE SUCH NOTICE SHALL BE DEEMED A WAIVER OF SUCH DEFECTS, IF
ANY, BY PURCHASER.  Upon timely receipt of notice of a Title Defect, Seller
may, at its sole discretion, take any steps it believes are reasonable in
attempting to eliminate such defect, but Seller shall be under no obligation to
cure any alleged Title Defect.  In the event Seller does not eliminate a Title
Defect, Purchaser shall have the option to either complete the purchase of the
Assets, notwithstanding the alleged Title Defect, or, upon written notice to
Seller, cancel this Agreement and the same shall be of no further force and
effect.

         (c)     In the event Seller's working interest and net revenue
interest in the Assets is different than the amounts set forth in Exhibit "A";
the Sale Price shall be appropriately adjusted by the same proportion that the
difference between the actual working interest and/or net revenue interest
bears to the working interest and/or net revenue interest set forth in Exhibit
"A".


                   VII.  OBLIGATIONS OF SELLER AND PURCHASER

         (a)     Purchaser agrees to reimburse Seller for the value of any and
all merchantable stock tank oil and/or condensate produced and saved as of 7:00
a.m. on the Effective Date hereof, at the prevailing market value, adjusted for
grade and gravity.  At 7:00 a.m. on the Effective Date hereof, Purchaser and
Seller shall make a joint gas sales meter reading and a joint oil and/or
condensate sales gauge reading.  If Purchaser does not participate in such
readings,





                                     - 5 -
<PAGE>   8
Purchaser agrees to accept the readings taken by Seller.  All revenues with
respect to Seller's interest in the Assets attributable to the production of
oil, gas, natural gas liquids and other salable substances commencing with
Effective Date shall be for the benefit of Purchaser.

         (b)     Except as provided for in Articles VII(c), VII(d) and X,
Seller shall retain all risk and liability of whatsoever nature connected with
operations conducted on the Assets prior to the Closing Date and agrees to
indemnify, defend and hold Purchaser harmless from all liabilities, penalties,
claims, causes of action, demands, lawsuits, and expenses associated with the
operations prior to the Closing Date.  Seller reserves and retains all claims
and accounts of Seller for recovery of money or damages, rights to insurance
and indemnity coverage, rights to tax refunds, and audit rights, if any, and
adjustments resulting therefrom attributable to the Assets with respect to any
period prior to the Effective Date.  Purchaser shall assume all risk and
liability of whatsoever nature connected with operations conducted on the
Assets from and after the Closing Date, and agrees to release, indemnify,
defend and hold Seller harmless from all liabilities, penalties, claims, causes
of action, demands, lawsuits, and expenses associated with the operations from
and after the Closing Date.

         (c)     Purchaser assumes full responsibility for, and agrees to
release, indemnify, hold harmless and defend Seller, its agents, officers, and
employees from and against all loss, liability, claims, fines, expenses, costs
(including attorney's fees and expenses) and causes of action caused by or
arising out of any federal, state or local laws, rules, orders and regulations
applicable to any waste material or hazardous substances on or included with
the Assets or the presence, disposal, release or threatened release of all
waste material or hazardous substance from the Assets into the atmosphere or
into or upon land or any water course or body of water, including ground water,
whether or not attributable to Seller's activities or the activities of
Seller's officers, employees or agents, or to the activities of third parties
(REGARDLESS OF WHETHER OR NOT SELLER WAS OR IS AWARE OF SUCH ACTIVITIES AND
REGARDLESS OF ANY CLAIMED NEGLIGENCE IN WHOLE OR IN PART ATTRIBUTABLE TO
SELLER) prior to, during or after the period of Seller's ownership of the
Assets.  This indemnification and assumption shall apply to liability for
voluntary environmental response actions undertaken pursuant either to the
Comprehensive Environmental Response Compensation and Liability Act (CERCLA),
as such may be amended from time to time, or to any other federal, state or
local law or regulation.

         (d)     Purchaser agrees to comply with all laws and governmental
regulations with respect to abandonment of wells and/or abandonment of the
leasehold property including, where applicable, plugging of wells, compliance
with laws or rules regarding inactive or unplugged wells, including bonding
requirements, and restoration as specified in the Leases. Purchaser agrees to
release, protect, defend, indemnify and hold Seller, its officers, agents and
employees free and harmless from and against any and all costs, expenses,
claims, demands and causes of action of every kind and character arising out of,
incident to, or in connection with the abandonment of wells and/or abandonment
of and proper disposition of any leasehold property, including, without
limitation, the Leases, any structures, materials, land, wells, casing,
leasehold equipment, and other personal property, plugging requirements or
exceptions thereto, including





                                     - 6 -
<PAGE>   9
bonding requirements, regardless of whether the liability therefor is based in
whole or in part upon some alleged act, negligence or omission of Seller, or of
the Purchaser, or of some other party.

         (e)     All accounts payable and other costs and expenses with respect
to the Seller's interest in the Assets incurred prior to the Effective Date
shall be the obligation of and be paid by Seller, and those incurred commencing
with the Effective Date shall be the obligation of and be paid by Purchaser.
Purchaser, however, shall have no obligation to Seller for the costs and
expenses that Seller incurred for the purchase of the Niject Gas Treating Plant
and Nitrogen Reinjection Facility located on the East Binger Unit premises, nor
shall Purchaser have any associated rights to the reimbursement to Seller from
the East Binger Unit Working Interest Owners for their share of the purchase of
said Plant and Facility.

         (f)     All prepaid utility charges applicable to periods following
the Effective Date relating to the Assets shall be prorated as of the Effective
Date pursuant to that Purchase and Sale Agreement dated January 8, 1998 between
Seller and Niject Corporation. 

         (g)     Seller shall transfer to Purchaser possession, responsibility
and liability for the management, administration, and disbursement of any
suspended funds attributable to the interests of third parties and accrued by
Seller, for any reason, pursuant to Seller's disbursement of proceeds from the
sale of production from the property or the Leases and/or units of which the
Assets are a part, to the extent such funds are attributable to production sold
prior to the Effective Date (collectively the "Suspended Funds"). The Suspended
Funds shall be transferred to Purchaser, subject to accounting adjustments, by
wire transfer, in immediately available funds in U.S. dollars for the account
of Purchaser, and Purchaser agrees to indemnify, defend and hold Seller
harmless from any claim relating to Purchaser's disposition and management of
said funds.

         Seller shall provide Purchaser a listing of all Suspended Funds,
setting forth the name (if known) of each interest owner, the decimal of
interest suspended, the amount suspended for each interest owner, the reason
the funds are in suspense and the date the interest was first suspended. 
Seller shall deliver to Purchaser, as soon after Closing as practicable, a copy
of Seller's records and files that apply to or are related to the Suspended
Funds transferred or assigned to Purchaser.

         If, in the administration or disposition of any of the Suspended Funds,
it is determined that Seller suspended excess funds, Purchaser shall promptly 
refund to Seller such excess amount.

         (h)     If monies are received by either party hereto which, under the
terms of this Article, belong to the other party, the same shall immediately be
paid over to the proper party. If an invoice or other evidence of an obligation
is received which is applicable to periods both prior to and after the
Effective Date and is thus, under the terms of the preceding paragraphs,
partially the obligation of Seller and partially the obligation of Purchaser,
then the parties shall consult with each other and each shall promptly pay its

         (i)     All ad valorem taxes relating to the Assets for the tax period
in which the Effective Date occurs shall be prorated as of the Effective Date
between Seller and Purchaser. The portion of such prorated tax liability which
is attributable to Seller shall be credited to Purchaser's account in the final
accounting statement provided for in sub-article XII(f) hereof. Purchaser shall
pay or cause to be paid to the taxing authorities all such taxes relating to
the tax period in which the Effective Date occurs. Purchaser shall supply
Seller with proof of payment promptly after paying same.

         All taxes, including, but not limited to, excise taxes, state
severance taxes, ad valorem taxes, and any other local, state, and/or federal
taxes or assessments attributable to the Assets or any part thereof prior to
the Effective Date, remain Seller's responsibility and all deductions, credits
and refunds relating to said taxes, attributable to the Assets or any part
thereof prior to the Effective Date (no matter when received), belong to
Seller. All such taxes attributable to the Assets or any part thereof at and
after the Effective Date are Purchaser's responsibility, and Purchaser shall
reimburse Seller for any such taxes previously paid by Seller and all
deductions, credits, and refunds relating thereto at and after the Effective
Date (no matter when received) belong to Purchaser.

         (j)     Purchaser shall be liable for any sales tax or other transfer
tax, as well as any applicable conveyance, transfer and recording fees and real
estate transfer stamps or taxes imposed on the transfer of the Assets pursuant
to this Agreement. Purchaser shall defend, indemnify and hold Seller harmless
with respect to the payment of any of these taxes, including any interest or
penalties assessed thereon. If Seller is required by applicable state law to
report and pay these taxes and/or fees, Purchaser shall, upon Seller's
presentation of an invoice, promptly deliver a check to Seller in full payment
of the invoice.

         (k)     Seller and Purchaser shall each bear their own costs and
expenses, including, but not limited to, attorney's fees and third-party
consultant fees, incurred in connection with the transactions contemplated in
this Agreement.

         (l)     The sale of the Assets shall be subject to, and Purchaser
shall assume, pay for and perform all duties, liabilities, and obligations
relating to the Assets, including, but not limited to, those imposed or 
required by any applicable and valid recorded or unrecorded contracts and 
agreements (including, but not limited to, royalties, production payments, 
net profits interests, carried working interests, required sale/delivery of 
oil or gas in accordance with any existing contracts, or similar burdens and 
commitments).

         (m)     Seller may require that a Letter of Credit in the format
attached as Exhibit "D" hereto, be established with a firm, approved by Seller, 
in the below described amounts to insure faithful performance of all lease
obligations from the Effective Date until the requisite government agency
approves the Department of Interior assignments, at which time said Letter of
Credit may be canceled.  This temporary letter of credit is to protect Seller's
exposure (plugging,





                                     - 8 -

abandonment, surface restoration, royalty payments, etc.) and is in addition to
any bonds required by the appropriate federal agencies. The responsible federal
agencies may require a period of six (6) months time or longer for their
approval assignment of the Leases. Said letter of credit shall be delivered to
Seller at or before Closing. The maximum amount of such Letter of Credit shall
be one hundred thousand dollars ($100,000.00).


                             VIII.  GAS IMBALANCES

         Purchaser hereby assumes any liability and obligation for gas
production imbalances (whether over or under) attributable to the interest
acquired hereunder as of the Effective Date. In assuming this liability,
Purchaser shall not be obligated to make any additional payment over the Sale
Price to Seller and Seller shall not be obligated to refund any of said price
to reimburse Purchaser for any over-balances existing at the time of sale.


                   IX.  ENVIRONMENTAL CONDITIONS/INDEMNITIES

         (a)     The Assets which have been identified herein and are the
subject of this Agreement have been utilized by Seller for the purpose of
exploration, development, processing, temporary storage, and transportation of
oil, gas and/or condensate. All information, to the best of Seller's knowledge,
regarding any substantial quantity of crude oil and produced water which may
have been spilled or disposed of onsite and the locations thereof, including pit
closures, burial, land farming, land spreading, and underground injection will
be made available to Purchaser at Seller's office within thirty (30) days of the
date of this Agreement; provided, however, that Seller shall not be liable for
unintentional failure to disclose such information.  Seller shall provide
information which is a matter of public record or filed with governmental
agencies and which Seller possesses in its files located in its offices.
Purchaser acknowledges that there may have been spills of these materials in the
past onto the Assets described herein. In addition, some oil and gas field
production equipment or flow lines may contain asbestos and/or Naturally
Occurring Radioactive Material (hereinafter referred to as "NORM"). In this
regard, Purchaser expressly understands that NORM may affix or attach itself to
the inside of wells, materials and equipment as scale, or in other forms, and
that said wells, material and equipment located on the property described herein
may contain NORM and that NORM-containing material may be buried or otherwise
disposed of on the Assets.  Purchaser also expressly understands that special
procedures may be required for the removal and disposal of asbestos and NORM
from the Assets where it may be found and Purchaser agrees to assume all
liability for such asbestos and NORM and for use of appropriate procedures and
activities required to handle and dispose of same.

         (b)     Promptly after execution of this Agreement by both parties,
Purchaser shall have the right at its own risk and expense, to conduct or have
conducted an environmental assessment of the Assets. Seller will provide
Purchaser (or its contractor) as may be requested with reasonable access to the
Assets operated by Seller to conduct the environmental assessment. Purchaser
shall release and indemnify and hold harmless Seller, its agents, officers and
employees against any liability or damage to persons or property arising out of
such environmental





                                     - 9 -
<PAGE>   12
assessment. Such indemnity shall also apply regardless of whether the liability
or damage arises in whole or in part from the negligence of Seller.

         (c)     Purchaser shall advise Seller in writing of any material
Adverse Environmental Conditions (as hereinafter defined) related to the Assets
and provide evidence thereof on or before May 1, 1998. For purposes of this
sub-article, such conditions shall be "material" only if they will cost in
excess of two percent (2%) of the Sale Price to cure or remedy and were not
disclosed on or before the execution of this Agreement. Not later than ten (10)
days after receipt of such written notice, Seller may either (1) remedy or
agree to remedy such material Adverse Environmental Conditions, (2) agree with
Purchaser on an adjustment to the Sale Price which adjustment shall reflect
Purchaser's cost to remedy such conditions, or (3) remove the asset or assets
from the Assets being conveyed and adjust the Sale Price accordingly; provided
that either Purchaser or Seller may cancel this Agreement if the aggregate
value of any excluded Assets exceeds twenty percent (20%) of the Sale Price. In
the event of such cancellation, neither party shall have any further obligation
hereunder.

                 As used herein, Adverse Environmental Conditions shall mean
any contamination or condition resulting from any discharge, release, disposal,
production, storage or treatment on or in the Assets or from the Assets to any
other land or body of water wherever located, prior to the Effective Date, of
any wastes, pollutant, contaminants, hazardous materials or other materials or
substances that are subject to regulation under laws in effect as of the
Effective Date relating to the protection of the environment.

         (d)     Purchaser shall dispose of or discharge any waste from the
Assets (including but not limited to produced water, drilling fluids and other
associated wastes) in accordance with applicable local, state and federal
regulations. To the extent that the Assets are not sold in fee to Purchaser,
Purchaser shall keep records of the types, amounts and location of wastes which
are disposed onsite and offsite. When and if any lease, an interest in which
has been assigned hereunder, is terminated, Purchaser shall take at its sole
expense whatever remedial action or cleanup of the Assets is necessary to meet
any local, state or federal requirements directed at protecting human health
and the environment in effect at that time, as well as whatever action may be
required to meet contractual or lease obligations related to the Assets.

         (e)     Purchaser, its successors and assigns, hereby releases and
agrees to indemnify and defend Seller, its agents, officers, employees,
successors and assigns, from and against all requirements, obligations, claims,
demands and causes of action, including, without limitation, any civil fines,
penalties, costs of clean-up or plugging liabilities for any and all wells,
brought by any and all persons, including, without limitation, Purchaser's and
Seller's employees, agents, or representatives and any private citizens,
persons, organizations, and any agency, branch or representative of federal,
state or local government, on account of any personal injury or death or damage,
destruction, or loss of property, contamination of natural resources (including
without limitation, soil, air, surface water or ground water) resulting from or
arising out of any liability or obligation caused by or connected with the
presence, disposal or release of any material of any





                                     - 10 -
<PAGE>   13
kind, including, without limitation, asbestos, NORM, solid waste, pollutants,
contaminants, hydrocarbons, or hazardous substance, in, under, or on the Assets
at the time the Assets are assigned to Purchaser, or thereafter caused by acts
of Purchaser, its employees, representatives, or agents with regard to its use
of the Assets subsequent to the assignment of the Assets pursuant to this
Agreement.

         (f)     THE INDEMNITIES, ASSUMPTIONS OF OBLIGATIONS, AND RELEASES, AS
SET FORTH IN (a), (b), (d), AND (e) OF THIS ARTICLE IX, SHALL APPLY WITHOUT
REGARD TO WHETHER OBLIGATIONS, LIABILITY, INJURY, DEATH, DAMAGE, DESTRUCTION,
LOSS OR CONTAMINATION IS CAUSED IN WHOLE OR IN PART BY ANY CLAIMED STRICT
LIABILITY, NEGLIGENCE, ACTIVE OR PASSIVE, ON THE PART OF SELLER OR OTHER
INDEMNIFIED PARTY. Such indemnities, assumptions of obligations, and releases
shall be in addition to any other indemnity provisions contained in this
Agreement, and it is expressly understood and agreed that the terms of this
Article shall control over any conflicting terms or provisions contained in
this Agreement and shall survive and remain as valid continuing covenants and
obligations following Closing.


                                 X.  OPERATIONS

         Seller, as to the portion of the Assets to be conveyed which it now
operates, shall from the date of execution of this Agreement, continue to
operate the same in a good and workmanlike manner until the Closing, when such
operations shall be turned over to and become the responsibility of Purchaser,
unless an applicable unit, pooling, communitization, operating or other
agreement requires otherwise, in which case (unless Purchaser and Seller
otherwise agree) Seller shall continue the physical operation of such portion of
the Assets pursuant to and under the terms of such applicable agreement, until
such time after the Closing as such applicable agreement may require; provided,
however, that Seller shall have no liability as operator to Purchaser for losses
or damages sustained, or liabilities incurred, except as may result directly
from Seller's gross negligence or willful misconduct. Such operations from and
after the Closing shall be conducted by Seller for and on behalf of Purchaser,
and Seller shall make appropriate charges to the to the Purchaser pursuant to
any applicable operating agreement. In the absence of any applicable operating
agreement, for any such services as operator of the Assets (or portions thereof)
performed by Seller from and after the Closing, Purchaser shall pay to Seller
all reasonable and necessary expenses incurred by Seller in such operation, or
in the protection or maintenance of the Assets. Any such charges and expenses
shall be recovered by Seller as part of the final accounting described in
sub-article XIII(f).


                           XI.  CONDITIONS OF CLOSING

and deliver all such further conveyances, transfer orders, notices, assumptions

indemnity is held to be invalid or unenforceable, then the parties intend and

         WHEREAS, Seller has initiated negotiations to acquire an additional
2,947 net acres of Oil, Gas and Mineral leases within the area outlined on
Exhibit A as the "Option Area"; and

         WHEREAS, Seller also has reason to believe that it can acquire
additional leases within the areas outlined as the "North Substitute Area" and
"South Substitute Area";

         NOW THEREFORE, for and in consideration of the delivery of certain
securities of Purchaser as set forth below and other good and valuable
consideration, the sufficiency of which is hereby acknowledged, Seller hereby
grants an exclusive option to Purchaser until May 25, 1995 (the "Option Date")
to purchase all or any portion of Seller's interests in oil, gas and mineral
leases ("Leases") and related property and equipment in the Contract Area, and
an exclusive option until 30 days following the Option Date to purchase all or
any portion of Leases Seller may purchase or contract to purchase in the Option
Area, all according to the following terms and conditions:

         1.      The securities (which shall be delivered to Seller on or
before March 15, 1995) shall consist of: (a) 8,131,333 shares of the Common
Stock of Purchaser, $0.001 par value (the "Common Stock"); (b) a warrant to

per share on or before March 15, 1996 (the "C$3.00 Warrant"); (c) a warrant to
purchase 2,032,833 shares of Common Stock at Four Canadian Dollars (C$4.00) per
share on or before March 15, 1997 (the "C$4.00 Warrant"); and (d) a warrant to
purchase 2,032,833 shares of Common Stock at Five Canadian Dollars (C$5.00) per

a securities acquisition agreement with respect to the securities being
acquired in the form of Exhibit B attached hereto. The warrants to be delivered
shall be in the form of Exhibit C attached hereto.

         2.      Each Lease delivered by Seller shall either: (i) have a
minimum of two years remaining primary term; or (ii) be held by production. To

Lease to Purchaser within 60 days following the Option Date. If, within 60 days
following the Option Date, Seller is unable to deliver good and marketable to
title to at least 4,000 net acres of Leases within the 25,000 barrel iso-
cumulative contour area shown in Exhibit A for the Contract Area and Option
Area, Seller shall use its best efforts to acquire and tender to Purchaser the
difference in net acres of Leases from the North Substitute Area and the South
Substitute Area.

         3.      The purchase price for the first 4,000 net acres of Leases
delivered by Seller and accepted by Purchaser within the Contract Area shall be
one hundred dollars ($100.00) per net acre, and the purchase price for the next
1,389 net acres of Leases within the Contract Area shall be twenty-one and
59/100 dollars ($21.59) per net acre. The purchase price for the Leases
delivered by Seller in the Option Area and Substitute Areas shall be one
hundred dollars ($ 100.00) per net acre.

         4.      All Leases assigned will have an average of 80.0% Net Revenue
Interest with the understanding that a 2.0% Overriding Royalty Interest (ORRI)
in the Contract Area and North Substitute Area will be assigned to Mr. Al
Jasper, Five Star Exploration Company, before subsequently assigning net 78%
revenue leases to Purchaser.

         5.      In order to exercise its option, Purchaser shall place into an
escrow account, on or before the Option Date, two hundred thousand dollars
($200,000.00), from which payments will be made to Seller as Leases meeting the
qualifications of Paragraph 2 above are assigned to Purchaser.

         6.      In the event Purchaser acquires a minimum of 2,000 net acres
of Leases within the Contract Area, Purchaser will agree to recomplete the
horizontal Texlan (ARCO) Billy Chandler #1 Well. Seller would have complete
access to the location and all test data.

         7.      An Area of Mutual Interest ("AMI") is hereby established with
respect to the North Cheneyboro Area and South Cheneyboro Area, as shown in
Exhibit A. Any interests in any Leases after 60 days beyond the Option Date
which are acquired by Seller within the AMI must be offered to the Purchaser at
Seller's cost within ten days after acquisition. An overriding royalty interest
of two percent (2%) shall be assigned to Mr. Al Jasper with respect to any
Leases acquired pursuant to this paragraph which lie within the North Area of
Mutual Interest as shown on Exhibit A.

         8.      On any re-entry by Purchaser of an existing wellbore for
horizontal recompletion within the North Area of Mutual Interest (including the
aforementioned Chandler Well), Seller will be carried for a reversionary one-
quarter Working Interest in such well, where the amount to be paid out includes
all costs of the Purchaser with respect to such well. On any new wellbore
drilled by Purchaser in the North Area of Mutual Interest, vertical or
horizontal, Seller will be carried for a one-sixteenth reversionary Working
Interest.

         9.      Any new acreage acquired by Purchaser in the AMI would be for
Purchaser's account with said acreage costs to be "loaded" on the first
commercial reentry or new well drilled in the AMI subsequent to acreage
acquisition.

         10.     In the event Purchaser elects to acquire at least 4,000 net
acres of Leases within the 25,000 barrel iso-cumulative contour as shown in
Exhibit A, and Seller is unable, within 60 days following the Option date, to
deliver good and merchantable title to at least 4,000 of said net acres, Seller
shall return to Purchaser shares of Common Stock, C$3.00 Warrants, C$4.00
Warrants and C$5.00 Warrants proportional to the amount of net acres of Leases
under 4,000 within the 25,000 barrel isocumulative contour that Seller is
unable to deliver. In the event Purchase does not exercise any portion of its
option hereunder, for any reason, Seller, upon written demand, shall return 50%
of amounts it previously received of Common Stock, C$3.00 Warrants, C$4.00
Warrants and C$5.00 Warrants.

         11.     This agreement shall be governed by the laws of the State of
Texas.

certified, or delivered by one Party to the other, to any third party and/or
filed with or delivered to any public officer in order to carry our the purpose
and intent of this Agreement, each Party hereto agrees to promptly execute and
deliver any and all such instruments reasonable necessary to carry out the

of which shall be deemed an original and each of which alone, and all of which
together, shall constitute one and the same instrument. It is agreed to that a
facsimile transmission signed copy of this Agreement shall be treated and

there is no other oral or written agreement or understanding between the
parties at the time of execution hereunder. In addition, this Agreement may be

hereto.

                          PURCHASE AND SALE AGREEMENT

         THIS AGREEMENT, made and entered into this 29th day of August, 1997, by
and between COTTON VALLEY RESOURCES CORPORATION, hereinafter referred to as
"BUYER" and CROWN PARTNERS L.L.C. MINERALS DIVISION hereinafter referred to as 
"SELLER".

         Seller owns the undivided interest described in Exhibit "A" in and to
the entire estates created by the oil and gas leases, Corporation Commission
Pooling Orders, operating agreements and other agreements affecting the
interests described in Exhibit "A" attached hereto and made a part hereof,
(hereinafter called the "Leases"), insofar as the Leases cover and related to
the land described in Exhibit "A" (hereinafter called the "Land"), together with
an identical undivided interest in and to all property and rights incident
thereto, including all rights in, to and under all agreements, product purchase
and sales contracts, leases, permits, rights-of-way, easements, licenses,
partnership rights, options and orders in any way relating thereto, in and to
all of the personal property, fixtures and improvements now or as of the
"Effective Time" (as hereinafter defined) thereon, appurtenant thereto or used
or obtained in connection therewith or with the production or treatment or sale
or disposal of liquid or gaseous hydrocarbons produced from or attributable to,
together with all other interests owned by Seller in and to said Land. All of
the foregoing are herein referred to as the "Interests".

         Seller desires to sell and convey and Buyer desires to purchase and
pay for the Interests set forth in the Exhibit "A", effective as of March 1,
1997 at 7:00 o'clock a.m. CDT (hereinafter referred to as the "Effective
Time").

         IN CONSIDERATION of the above recitals and of the benefits to be
derived by each Party under this Agreement, it is agreed as follows:

         1.      Sale and Purchase - Seller agrees to sell and convey and Buyer
agrees to purchase and pay for that portion of the Interests set forth on
Exhibit "A", subject to the terms of this Agreement.

         2.      Purchase Price - The aggregate purchase price for the
Interests shall be $34,545.00.

         3.      Title Information - Seller shall make available to Buyer title
information pertaining to the Interests prior to Closing including copies of
all title opinions, title reports, and division orders pertaining to the
Interests heretofore received by Seller or to which Seller has reasonable
access.
<PAGE>   2
         All such information now in possession of Seller shall also be open to
inspection by Buyer at any reasonable time from the date hereof through the
closing of title to the interests herein (the "Closing") or the termination of
this Agreement. If such information or any other information or date shall
reflect the existence of any encumbrance, encroachment, defect in or objection
to title which Buyer does not waive (all of which are herein called the "Title
Defects"), written notice of the Title Defects shall be given to Seller prior to
Closing. No matter shall be construed as a Title Defect unless so construed
under generally accepted oil and gas industry title examination standards for
the State of Oklahoma. If Title Defects shall be so specified, Seller may make
reasonable effort to cure or remove all of the Title Defects at the expense of
Seller.

         If Title Defects are not cured or removed at or before the Closing,
Buyer may elect in writing to either: (1) extend the Closing Date and during
such extension Seller may make a good faith effort to cure and remove the Title
Defects; (2) waive the Title Defects and proceed with the Closing; or (3)
terminate this Agreement. If this Agreement is so terminated or terminated under
any other provision of this Agreement, Buyer shall return to Seller all of the
items which Seller has delivered to Buyer hereunder. If this Agreement is
terminated for any reason or is breached, this paragraph shall not be construed
to limit Seller's or Buyer's legal or equitable remedies.

         4.      Seller's Representations - Seller represents, warrants and
agrees as to its respective Interests to and with Buyer that:

         (a)      The Interests will be free and clear of all liens and
                  encumbrances by Closing, and Seller has provided
                  Buyer with Seller's information relating to the
                  Interests including but not limited to production
                  information, product pricing information and lease
                  operating expense.
         
         (b)      To the knowledge of Seller, the Leases are in full force and
                  effect, are valid and subsisting, and cover the entire estate
                  which they purport to cover, and Seller has never been advised
                  directly or indirectly by any Lessor under any Lease or by any
                  other Party of a default under any Lease or of any
                  requirements or demands to drill additional wells on any of
                  the Land covered by the Leases.
         
         (c)      The Interests entitle Seller to receive not less than
                  the undivided Interests shown on Exhibit "A" as "Net
                  Revenue Interests" of all indicated hydrocarbons
                  produced, saved and marketed from the Land and all
                  Wells located thereon. Seller's obligation to bear
                  costs and expenses relating to the development of and
                  operations on the Leases, Land and Wells thereon will
                  not be greater than the "Working Interests" set forth
                  on Exhibit "A".
         
         (d)      It is understood that Seller will warrant and forever
                  defend the title of Buyer as to the acts of Seller to the
                  Interests against all claims made by, through and under
                  Seller, but not otherwise.

PetroGreen Agreement (hereinafter the "Offshore Pacific First Payment Date"),
Cotton Valley shall pay Offshore Pacific $100,000 by the delivery of a
cashier's check or bank wire transfer. If such payment is not timely made, the
PetroGreen Agreement shall be deemed to have been automatically assigned by
Cotton Valley to Offshore Pacific as of the Offshore Pacific First Payment
Date. Upon receipt of the payment, Offshore Pacific shall renounce and release
any claims it may have with respect to the Conoco Option Agreement, except as
set forth in this Offshore Pacific Agreement.

         3.      The parties hereto contemplate that the PetroGreen Agreement
will provide for a $200,000 payment to be made to PetroGreen by Cotton Valley
on or before June 30, 1995, or such other date as may be mutually agreeable
between PetroGreen and Cotton Valley (hereinafter the "PetroGreen First Payment
Date"). If such payment is not timely made, the PetroGreen Agreement shall be
deemed to have been automatically assigned by Cotton Valley to Offshore Pacific
as of the PetroGreen First Payment Date.

         4.      The parties hereto further contemplate that the PetroGreen
Agreement will provide for a closing of the property purchase under the Conoco
Option Agreement (the "Closing") whereby Cotton Valley will make certain cash
payments to PetroGreen and Conoco, and will further provide that Cotton Valley
would have the right to be assigned the entire 51.79217% interest being
acquired from Conoco. At the Closing, Cotton Valley will deliver Offshore
Pacific the following payments, marketable securities, and interests, LESS AND
EXCEPT those payments, marketable securities, and interests which are paid by
Cotton Valley at Closing to PetroGreen under the PetroGreen Agreement, which
are paid by Cotton Valley at closing to Conoco under the Conoco Option
Agreement, and which are paid by Cotton Valley to MIRO at Closing under the
MIRO Agreement:

         A.      Cash in the form of cashier's check or bank wire transfer in
the amount of $8,000,000.

         B.      $4,000,000 market value of marketable securities of publicly
         traded corporations reasonably acceptable to Offshore Pacific and
         engaged principally in the oil and gas industry, where: (i) the amount
         of any single

Offshore Pacific--Cotton Valley Agreement .....Page 2
<PAGE>   3
         security delivered must be less than 10% of the total amount which is
         issued and outstanding of that security; and (ii) any security
         delivered must be listed and tradable on at least one of the
         following: New York Stock Exchange, American Stock Exchange, Midwest
         Stock Exchange, Pacific Stock Exchange, Toronto Stock Exchange,
         Vancouver Stock Exchange, Alberta Stock Exchange, NASDAQ National
         Market or NASDAQ Small Cap Market. Any affiliate of Cotton Valley
         meeting the two foregoing requirements shall be deemed acceptable to
         Offshore Pacific.

         C.      A carried working interest in the Sword Unit equal to
         6.79217%, whereby the remaining 45% interest shall pay all capital
         costs and expenses of the carried working interest through the
         completion of construction of the first offshore multi-well production
         platform and the drilling and completion of the first ten development
         wells.

         5.      During the year following the PetroGreen Payment Date, Cotton
Valley shall use its best efforts to sell at least two-thirds of its rights
under this offshore Pacific Agreement, the PetroGreen Agreement and the Conoco
Option Agreement (collectively, the "Rights") to other independent oil and gas
producing entities. To the extent that Cotton Valley is successful in selling a
portion of its Rights to entities who are willing to pay Cotton Valley more
than a pro rata share of Cotton Valley's purchase price and other payments
under the foregoing agreements, 50% of the excess proceeds from such sales
shall be paid by Cotton Valley to Offshore Pacific as received. If Cotton
Valley is able to require some of such entities to post some of Cotton Valley's
portion of the letter of credit required in the Conoco Option Agreement,
Offshore Pacific will not share in that benefit. A copy of each letter of
intent or agreement representing a sale shall be sent by Cotton Valley to
Offshore Pacific within ten business days of execution.

         6.      In the event that Cotton Valley has not entered into binding
agreements to sell at least 30% working interest in the Sword Unit from its
Rights by one year from the PetroGreen Payment Date, Cotton Valley shall assign
to Offshore Pacific any amounts of Rights it retains exceeding 15% working
interest in the Sword Unit, after taking into account delivery of the 6.79217%
carried working interest; and Cotton Valley shall deliver to Offshore Pacific
copies of all its correspondence with potential purchasers.

         7.      Both parties agree that operations of the Sword Unit, after
acquisition from Conoco, should be undertaken by an oil and gas company with
significant offshore experience and capability and will use their respective
best efforts to encourage Samedan Petroleum Corporation to become the operator.
If Cotton Valley sells of any of its interests as contemplated in Paragraph 5
above, Cotton Valley shall reserve and the retain voting rights

Offshore Pacific--Cotton Valley Agreement .....Page 3
<PAGE>   4
for operator under the Sword Unit Operating Agreement with respect to the
interest sold. Cotton Valley shall vote for Unit Operator as directed in
writing by Offshore Pacific.

         8.      The parties have previously executed the Confidentiality
Agreement attached hereto as Exhibit C.  Offshore Pacific specifically
authorizes Cotton Valley to provide confidential information and data as
defined in the Confidentiality Agreement to potential investors in Cotton
Valley or the Sword Unit, provided, however, that each such potential investor
execute a similar confidentiality agreement with Cotton Valley, and further
provided, however, that a copy of this Offshore Pacific Agreement may not be
shown to any person or entity without specific written approval from Offshore
Pacific with respect to such person or entity.

         9.      This Offshore Pacific Agreement shall be governed by the laws
of the State of Texas.

         10.     Should any additional instruments need to be executed,
certified, or delivered by one Party to the other, to any third party and/or
filed with or delivered to any public officer in order to carry out the purpose
and intent of this Offshore Pacific Agreement, each Party hereto agrees to
promptly execute and deliver any and all such instruments reasonable necessary
to carry out the purpose and intent of this Offshore Pacific Agreement.

         11.     This Offshore Pacific Agreement may be executed in multiple
counterparts, each of which shall be deemed an original and each of which
alone, and all of which together, shall constitute one and the same instrument.
It is agreed to that a facsimile transmission signed copy of this Offshore
Pacific Agreement shall be treated and considered an original for all intended
purposes.

     8.2.    Successors.  This Agreement shall be binding upon Borrower and its
successors and assigns, and shall inure to the benefit of Lender and its 
successors and assigns.

     8.3.    Counterparts.  This Agreement may be executed in any number of 
counterparts and all of said counterparts taken together shall be deemed to 
constitute one and the same instrument.

     8.4.    Severability.  In case any one or more of the provisions contained

contained herein and therein shall not in any way be affected thereby.

     8.5.    Usury Savings Clause.  It is the intention of the parties hereto 
to comply with the laws of the State of Texas; accordingly, it is agreed that 
notwithstanding any provisions to the contrary in this Agreement, the Notes or

holders of the Notes or obligations be entitled to contract for, receive, 
collect or apply, as interest on said Notes and Obliga-

                                      -9-
<PAGE>   10

tions, any amount in excess of the maximum amount permitted by such laws of the
State of Texas, nor shall this Agreement or such instruments or documents
require the payment or permit the collection of interest, as defined under the
laws of the State of Texas, in excess of the maximum amount permitted by such
law. If any such excess of interest is contracted for, charged or received,
under this Agreement, the Notes or otherwise or the indebtedness evidenced by
the Notes is accelerated in whole or in part, or in the event that all or part
of the principal or interest of the Notes shall be prepaid, so that under any
of such circumstances the amount of interest contracted for, charged or
received under this Agreement, the Notes, or under any of the instruments
otherwise relating hereto, on the amount of principal actually outstanding from
time to time under the Notes shall exceed the maximum amount of interest
permitted by the laws of the State of Texas, then in any such event (a) the
provisions of this Section shall govern and control, (b) neither Borrower nor
any other person or entity now or hereafter liable for the payment of the
Notes shall be obligated to pay the amount of such interest to the extent that
it is in excess of the maximum amount of interest permitted to be contracted
for by, charged to or received from the party obligated thereon under the laws
of the State of Texas, (c) any such excess which may have been collected shall
be either applied as a credit against the then unpaid principal amount on the
Notes or refunded to the person paying the same, at the holder's option, and
(d) the effective rate of interest shall be automatically reduced to the
maximum lawful rate of interest permitted to be contracted for by, charged to
or received from the party obligated thereon under the laws of the State of
Texas as now or hereafter construed by the courts having jurisdiction thereof.
It is further agreed that without limitation of the foregoing, all calculations
of the rate of interest contracted for, charged or received under this
Agreement, the Notes, or under such other documents which are made for the
purpose of determining whether such rate exceeds the maximum lawful rate of
interest, shall be made to the extent permitted by the laws of the State of
Texas, by amortizing, prorating, allocating and spreading in equal parts during
the period of the full stated term of the Notes, all interest at any time
contracted for, charged or received from the undersigned or otherwise by the
holder or holders thereof in connection with the Notes.

                             SUBSCRIPTION AGREEMENT

         Cotton Valley Resources Corporation, and its wholly owned subsidiary,
Cotton Valley Energy Corporation, (collectively the "Company"), propose to
issue and sell promissory notes and warrants (the "Securities") to certain
investors in a transaction exempt from the registration requirements of the
Securities Act of 1933. The availability of this exemption depends in part upon
the nature of the purchasers in the offering. In order to satisfy its due
diligence obligations with respect to the qualifications of such investors to
participate in the offering, the Company requests that the undersigned investor
certify as to the following items:

         1.      The undersigned has had an opportunity to ask questions and
receive answers from the Company or a person or persons acting on its behalf,
concerning the terms and conditions of this investment and has had an
opportunity to examine all applicable documents and information, to the extent
such documents and information are relevant to this transaction and are
possessed by the Company or are obtainable by the Company without unreasonable
effort or expense, and all such questions have been answered and documents and
information have been supplied to the full satisfaction of the undersigned.

         2.      The undersigned understands that an investment in the Company
may be an illiquid investment and further recognizes and agrees that the
undersigned's investment in the Company will, most likely, be held for a
lengthy period of time.

         3.      The undersigned acknowledges that there are substantial
restrictions on the transferability of the Securities. The Securities may not
be, and the undersigned agrees that they shall not be, sold unless such sale is
exempt from such registration under the Securities Act and any other applicable
state blue sky laws or regulations. The undersigned also acknowledges
responsibility for compliance with all conditions on transfer imposed by any
securities administrator of any state.

         4.      The undersigned is an "Accredited Investor", as such term is
defined in Rule 501 promulgated under the Securities Act. Accredited Investors
include (a) any natural person whose net worth, or joint net worth with that
person's spouse, at the time of his purchase exceeds $1,000,000,and (b) any
natural person who had an individual income in excess of $200,000 in each of
the two most recent years or joint income with that person's spouse in excess
of $200,000 in each of those years and has a reasonable
<PAGE>   14
expectation of reaching the same income level in the current year.

         5.      The undersigned is acquiring the Securities for which he
hereby subscribes for his own account, as principal, for investment purposes
only and not with a view to the distribution thereof.

         6.      The undersigned has adequate means of providing for his
current needs and personal contingencies and has no need for liquidity in his
investment.

         7.      The undersigned has such knowledge and experience in financial
and business matters as to be capable of evaluating the merits and risks of the
proposed investment. The undersigned can bear the economic risks in and can
afford a complete loss of any investment he may make by virtue of his
purchasing Securities and can afford to hold any such investment for an
indefinite period.

         8.      The undersigned has previously purchased securities which were
sold in reliance on a private offering exemption for registration under the
Securities Act.

         9.      The undersigned desires to purchase a promissory note in the
amount set forth below and to purchase. 40 warrants for each dollar the subject
of such note below from the Company. Such purchase is subject to the terms of a
Loan Agreement dated July 18, 1997, executed by the Company.

         10.     By executing this Subscription Agreement, the undersigned
authorizes the Company to attach it as Exhibit "A" to a Loan Agreement dated
July 18, 1997 (the "Loan Agreement"). The undersigned agrees to the terms and
conditions of the Loan Agreement.

any such excess shall be canceled automatically as of the acceleration or
prepayment or, if already paid, credited on the principal of the debt or, if
the principal of the debt has been paid, refunded. This provision overrides
other provisions in this and all other instruments concerning the debt.

BENEFICIARY'S RIGHTS.

         1.      Beneficiary may appoint in writing a substitute or successor
                 trustee, succeeding to all rights and responsibilities of the
                 original trustee.

         2.      If the proceeds of the Notes are used to pay any debt secured
                 by prior liens, Beneficiary is subrogated to all of the rights
                 and liens of the holders of any debt so paid.

         3.      If Grantor fails to perform any of Grantor's obligations,
                 Beneficiary may perform those obligations and be reimbursed by
                 Grantor, on demand, at the place where the Notes is payable
                 for any sums so paid, including attorney's fees, plus interest
                 on those sums from the dates of payment at the rate stated in
                 the Notes for mature, unpaid amounts. The sum to be reimbursed
                 shall be secured by this deed of trust.

         4.      If Grantor defaults on any one of the Notes or fails to
                 perform any of Grantor's obligations or if default occurs on a
                 prior lien Notes or other instrument, and the default
                 continues after Beneficiary gives Grantor notice of the
                 default and the time within which it must be cured, as may be
                 required by law or by the Loan Agreement, then Beneficiary
                 may:

                 a. declare the unpaid principal balance and earned interest 
                 on the Notes immediately due; 

                 b. Request Trustee to foreclose this lien, in which case 
                 Beneficiary or Beneficiary's agent shall give notice of the
                 foreclosure sale as provided by The Texas Property Code as
                 then amended; and 

                 c. purchase the property at any foreclosure sale by offering
                 the highest bid and have the bid credited on the Notes.

         5.      All individuals (or entities) who are Beneficiary shall share
                 such rights, interests, and benefits as are created hereunder
                 on a pro rata basis, based on the ratio that the amount of the
                 note held by an individual (or entity) bears to the total
                 dollar amount of the Notes held collectively by the
                 Beneficiary. Any foreclosure conducted pursuant to this Deed
                 of Trust or any voluntary or involuntary transfer of assets by
                 Grantor to Beneficiary, shall be for the benefit of and shares
                 by all of the Beneficiary on the pro rata basis as set forth
                 above.

TRUSTEE'S DUTIES.

         If requested by Beneficiary to foreclose this lien, Trustee shall:

         1.      either personally or by agent give notice of the foreclosure
                 sale as required by The Texas Property Code as then amended;

         2.      sell and convey all or part of the property to the highest
                 bidder for cash with a general warranty binding Grantor
                 subject to prior liens and to other exceptions to conveyance
                 and warranty; and

         3.      from the proceeds of the sale, pay, in this order:

                 a.       actual expenses of foreclosure;

                 b.       to Beneficiary, the full amount of principal,
                          interest, attorney's fees, and other charges due and
                          unpaid as set forth under Section 5, Beneficiary's
                          Rights;

                 c.       any amounts required by law to be paid before
                          payment to Grantor; and 

                 d.       to Grantor, any balance.

GENERAL PROVISIONS.

         1.      If any of the property is sold under this deed of trust,
                 Grantor shall immediately surrender possession to the
                 purchaser. If Grantor fails to do so, Grantor shall become a
                 tenant at sufferance of the purchaser, subject to an action
                 for forcible detainer.

         2.      Recitals in any trustee's deed conveying the property will be
                 presumed to be true.

         3.      Proceeding under this deed of trust, filing suit for
                 foreclosure, or pursuing any other remedy will not constitute
                 an election of remedies.

         4.      If any portion of the Notes cannot be lawfully secured by this
                 deed of trust, payments shall be applied first to discharge
                 that portion.

         5.      Grantor assigns to Beneficiary all sums payable to or received
                 by Grantor from condemnation of all or part of the property,
                 from private sale in lieu of condemnation, and from damages
                 caused by public works or construction on or near the
                 property. After deducting any expenses incurred, including
                 attorney's fees, Beneficiary may release any remaining sums to
                 Grantor or apply such sums to reduce the Notes.
<PAGE>   26
                 Beneficiary shall not be liable for failure to collect or to
                 exercise diligence in collecting any such sums.

         6.      Grantor collaterally assigns to Beneficiary, all present and
                 future income and production from the Property. Grantor
                 warrants the validity and enforceability of the assignment.
                 Beneficiary neither has nor assumes any obligations as lessee
                 with respect to the Property. Beneficiary is not required to
                 act under this paragraph, and acting under this paragraph does
                 not waive any of Beneficiary's other rights or remedies. If
                 Grantor becomes a voluntary or involuntary bankrupt,
                 Beneficiary's filing a proof of claim in bankruptcy will be
                 tantamount to the appointment of a receiver under Texas law.

         7.      Interest on the debt secured by this deed of trust shall not
                 exceed the maximum amount of nonusurious interest that may be
                 contracted for, taken, reserved, charged, or received under
                 law; any interest in excess of that maximum amount shall be
                 credited on the principal of the debt or, if that has been
                 paid, refunded. On any acceleration or required or permitted
                 prepayment, any such excess shall be canceled automatically as
                 of the acceleration or prepayment or, if already paid,
                 credited on the principal of the debt or, if the principal of
                 the debt has been paid, refunded. This provision overrides
                 other provisions in this and all other instruments concerning
                 the debt.

         8.      When the context requires, singular nouns and pronouns include
                 the plural.

         9.      The term "Notes" includes all sums secured by this deed of
                 trust.

         10.     This deed of trust shall bind, inure to the benefit of, and be
                 exercised by successors in interest of all parties.

         11.     If Grantor and Maker are not the same person, the term Grantor
                 shall include Maker.

         12.     Grantor represents that this deed of trust and the Notes are
                 given for the following purposes: The indebtedness, the
                 payment of which is hereby secured, represents cash that
                 Beneficiary advanced to Grantor on this day at Grantor's
                 request and that Grantor acknowledges receiving.

         13.     In addition to creating a deed of trust lien on all the real
                 and other property described above, Grantor also grants to
                 Beneficiary a security interest in all
<PAGE>   27
                 Property other than the realty pursuant to the Texas Uniform
                 Commercial Code. In the event of a foreclosure sale under this
                 Deed of Trust, Grantor agrees that all the Property may be
                 sold as a whole at Beneficiary's option and that the Property
                 need not be present at the place of sale.

note dated July 18, 1997, executed by Cotton Valley Energy Corporation, and
payable to the order of____________, in the sum of $ __________ (the "Note"),
according to its terms to the same extent as if the Company were maker of the
Note. Except as set forth in that certain Loan Agreement dated July 18, 1997
between Cotton Valley Energy Corporation and the Payee of the Note, the Company
waives all demands for payment, presentations for payment, notices of intention

EXERCISE OF THE WARRANTS HAVE NOT BEEN REGISTERED OR QUALIFIED UNDER THE

FROM SUCH REGISTRATION OR QUALIFICATION IS APPLICABLE.


                      COTTON VALLEY RESOURCES CORPORATION

             Incorporated Under the Laws of the Province of Ontario

No.                                                               Common Stock

                          CERTIFICATE FOR COMMON STOCK
                               PURCHASE WARRANTS

     1.   Warrant. This Warrant Certificate certifies that      , or registered
assigns (the "Registered Holder"), is the registered owner of the above
indicated number of Warrants expiring on the Expiration Date, as hereinafter
defined. One (1) Warrant entitles the Registered Holder to purchase one (1)
share of the common stock (a "Share") of Cotton Valley Resources Corporation,
an Ontario corporation (the "Company"), from the Company at a purchase price of
Two Dollars and Eight Cents (US$2.08) (the "Exercise Price") at any time during
the Exercise Period, as hereinafter defined, upon surrender at the principal
office of the Company of this Warrant Certificate with the exercise form
appended hereto duly completed and executed and accompanied by payment of the
Exercise Price.

          Upon due presentment for transfer or exchange of this Warrant
Certificate at the principal office of the Company, a new Warrant Certificate
or Warrant Certificates of like tenor and evidencing in the aggregate a like
number of Warrants shall be issued in exchange for this Warrant Certificate,
subject to the limitations provided herein, upon payment of any tax or
governmental charge imposed in connection with such transfer. Subject to the
terms hereof, the Company shall deliver Warrant Certificates in required whole
number denominations to Registered Holders in connection with any transfer or
exchange permitted hereunder.

     2.   Restrictive Legend. Each Warrant Certificate and each certificate
representing Shares issued upon exercise of a Warrant, unless such Shares are
then 



                                      -1-
<PAGE>   36
registered under the Securities Act of 1933, as amended (the "Act"), shall bear
a legend in substantially the following form:
     
     "THE [SECURITIES] REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     OR QUALIFIED UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES OR BLUE SKY
     LAWS OF ANY STATE AND MAY BE OFFERED AND SOLD ONLY IF REGISTERED AND
     QUALIFIED PURSUANT TO RELEVANT PROVISIONS OF FEDERAL AND STATE SECURITIES
     OR BLUE SKY LAWS OR IF AN EXEMPTION FROM SUCH REGISTRATION OR QUALIFICATION
     IS APPLICABLE."

     3.   Exercise. Subject to the terms hereof, the Warrants evidenced by this
Warrant Certificate may be exercised at the Exercise Price in whole or in part
at any time during the period (the "Exercise Period") commencing on June 18,
1997 and terminating at 5:00 p.m., Central standard time, on April 30, 2002
(the "Expiration Date"). The Exercise Period may be extended by the Company's
Board of Directors.

          A Warrant shall be deemed to have been exercised immediately prior to
the close of business on the date (the "Exercise Date") of the surrender to the
Company at its principal offices of this Warrant Certificate with the exercise
form attached hereto completed and executed by the Registered Holder and
accompanied by payment to the Company, in cash or by check (which shall be
accepted subject to collection), of an amount equal to the aggregate Exercise
Price for the Warrants being exercised, in lawful money of Canada.

          The person entitled to receive the Shares issuable upon exercise of a
Warrant or Warrants ("Warrant Shares") shall be treated for all purposes as the
holder of such Warrant Shares as of the close of business on the Exercise Date.
The Company shall not be obligated to issue any fractional share interests in
Warrant Shares issuable or deliverable on the exercise of any Warrant or scrip
or cash with respect thereto, and such right to a fractional share shall be of
no value whatsoever. If more than one Warrant shall be exercised at one time by
the same Registered Holder, the number of full Shares which shall be issuable on
exercise thereof shall be computed on the basis of the aggregate number of full
shares issuable on such exercise.

          Promptly, and in any event within ten business days after the
Exercise Date, the Company shall cause to be issued and delivered to the person
or persons entitled to receive the same, a certificate or certificates for the
number of Warrant Shares deliverable on such exercise.

          The Company may deem and treat the Registered Holder of the Warrants
at any time as the absolute owner thereof for all purposes, and the Company
shall not be affected by any notice to the contrary. The Warrants shall not
entitle the Registered



                                      -2-
<PAGE>   37
Holder thereof to any of the rights of shareholders or to any dividend declared
on the Shares unless the Registered Holder shall have exercised the Warrants
and thereby purchased the Warrant Shares prior to the record date for the
determination of holders of Shares entitled to such dividend or other right.

     4.   Reservation of Shares and Payment of Taxes. The Company covenants
that it will at all times reserve and have available from its authorized Common
Stock such number of Shares as shall then be issuable on the exercise of
outstanding Warrants. The Company covenants that all Warrant Shares which shall
be so issuable shall be duly and validly issued, fully paid and nonassessable,
and free from all taxes, liens and charges with respect to the issue thereof.

          The Registered Holder shall pay all documentary, stamp or similar
taxes and other government charges that may be imposed with respect to the
issuance, transfer or delivery of any Warrant Shares on exercise of the
Warrants. In the event the Warrant Shares are to be delivered in a name other
than the name of the Registered Holder of the Warrant Certificate, no such
delivery shall be made unless the person requesting the same has paid the
amount of any such taxes or charges incident thereto.

    5.  Registration of Transfer. The Warrant Certificates may be transferred
in whole or in part, provided any such transfer complies with all applicable
securities laws. Warrant Certificates to be transferred shall be surrendered to
the Company at its principal office. The Company shall execute, issue and
deliver in exchange thereof the Warrant Certificate or Certificates which the
Registered Holder making the transfer shall be entitled to receive.

        The Company shall keep transfer books at its principal office which
shall register Warrant Certificates and the transfer thereof. On due
presentment of any Warrant Certificate for registration of transfer at such
office, the Company shall execute, issue and deliver to the transferee or
transferees a new Warrant Certificate or Certificates representing an equal
aggregate number of Warrants. All Warrant Certificates presented for
registration of transfer or exercise shall be duly endorsed or be accompanied
by a written instrument or instruments of transfer in form satisfactory to the
Company. The Company may require payment of a sum sufficient to cover any tax
or other government charge that may be imposed in connection therewith.

        All Warrant Certificates so surrendered, or surrendered for exercise,
or for exchange in case of mutilated Warrant Certificates, shall be promptly
canceled by the Company and thereafter retained by the Company until the
Expiration Date. Prior to due presentment for registration of transfer thereof,
the Company may treat the Registered Holder of any Warrant Certificate as the
absolute owner thereof (notwithstanding any notations of ownership or writing
thereon made by anyone other 



                                     - 3 -
<PAGE>   38
than the Company), and the Company shall not be affected by any notice to the
contrary.

     6.   Loss or Mutilation. On receipt by the Company of evidence
satisfactory as to the ownership of and the loss, theft, destruction or
mutilation of this Warrant Certificate, the Company shall execute and deliver,
in lieu thereof, a new Warrant Certificate representing an equal aggregate
number of Warrants. In the case of loss, theft or destruction of any Warrant
Certificate, the individual requesting issuance of a new Warrant Certificate
shall be required to indemnify the Company in a form and amount satisfactory to
the Company. In the event a Warrant Certificate is mutilated, such Certificate
shall be surrendered and canceled by the Company prior to delivery of a new
Warrant Certificate. Applicants for a new Warrant Certificate shall also comply
with such other regulations and pay such other reasonable charges as the
Company may prescribe.

     7.   Adjustment of Shares. The number and kind of securities issuable
upon exercise of a Warrant shall be subject to adjustment from time to time
upon the happening of certain events, as follows:

               (a)  Stock Splits, Stock Combinations and Certain Stock
          Dividends. If the Company shall at any time subdivide or combine its
          outstanding Shares, or declare a dividend in Shares or other
          securities of the Company convertible into or exchangeable for Shares,
          a Warrant for the same Exercise Price shall, after such subdivision or
          combination or after the record date for such dividend, be exercisable
          for that number of Shares and other securities of the Company that the
          Registered Holder would have owned immediately after such event with
          respect to the Shares and other securities for which a Warrant may
          have been exercised immediately before such event had the Warrant been
          exercised immediately before such event. Any adjustment under this
          Section 7(a) shall become effective at the close of business on the
          date the subdivision, combination or dividend becomes effective.

               (b)  Adjustment for Reorganization, Consolidation, Merger. In
          case of any reorganization of the Company (or any other corporation
          the stock or other securities of which are at the time receivable upon
          exercise of a Warrant) or in case the Company (or any such other
          corporation) shall merge into or with or consolidate with another
          corporation or convey all or substantially all of its assets to
          another corporation or enter into a business combination of any form
          as a result of which the Shares or other securities receivable upon
          exercise of a Warrant are converted into other stock or securities of
          the same or another corporation, then and in each such case, the
          Registered Holder of a Warrant, upon exercise of the purchase right at
          any time after the consummation of such reorganization, consolidation,
          merger, conveyance or combination, shall for the 


                                      -4-
<PAGE>   39
     same Exercise Price be entitled to receive, in lieu of the Shares or other
     securities to which such Registered Holder would have been entitled had he
     exercised the purchase right immediately prior thereto, such stock and
     securities which such Registered Holder would have owned immediately after
     such event with respect to the Shares and other securities for which a
     Warrant may have been exercised immediately before such event had the
     Warrant been exercised immediately prior to such event.

          In each case of an adjustment in the Shares or other securities 
receivable upon the exercise of a Warrant, the Company shall promptly notify the
Registered Holder of such adjustment. Such notice shall set forth in reasonable
detail the facts upon which such adjustment is based.

     8.   Reduction in Exercise Price at Company's Option. The Company's Board
of Directors may, at its sole discretion, reduce the Exercise Price of the
Warrants in effect at any time either for the remaining life of the Warrants or
any shorter period of time determined by the Company's Board of Directors.  The
Company shall promptly notify the Registered Holders of any such reduction in
the Exercise Price.

     9.   Registration Rights.

(a)                      If, at any time during the Exercise Period and the
three (3) years following any exercise hereunder, the Company proposes to file
a registration statement with respect to any class of securities (other than
pursuant to a registration statement on Forms S-4 or S-8 or any successor form)
under the Securities Act, the Company shall notify the Registered Holder at
least twenty (20) days prior to the filing of such registration statement and
will offer to include in such registration statement all or any portion of the
Warrant Shares. In a written notice to be delivered to the Company within twenty
(20) days after receipt of any such notice from the Company, the Registered 
Holder shall state the number of Warrant Shares that it wishes to register for 
resale and distribution publicly under the proposed registration statement.  The
Company will use its best efforts, through its officers, directors, auditors and
counsel in all matters necessary or advisable, to file at least one (1) such 
registration statement by November 30, 1997. The Company will also use its best
efforts, through its officers, directors, auditors and counsel in all matters
necessary or advisable, to include within the coverage of each such registration
statement (except as hereinafter provided) the Warrant Shares that Registered
Holder has advised the Company that Registered Holder wishes to register
pursuant to such registration statement for resale and distribution, to
prosecute each such registration statement diligently to effectiveness, to cause
such registration statement to become effective as promptly as practicable, and
to register or qualify the securities so being registered under such state and
provincial securities or "blue sky" laws as the Registered Holder may
reasonably request.  In that regard, the


                                      -5-


<PAGE>   40
Company makes no representations or warranties as to its ability to have any
registration statement declared effective.

    All registrations requested pursuant to this Section 9(a) are referred to
herein as "Piggyback Registrations." In the event the Company is advised by the
staff of the Securities and Exchange Commission, Nasdaq Stock Market or any
self-regulatory or state securities agency that the inclusion of the Warrant
Shares will prevent, preclude or materially delay the effectiveness of a
registration statement filed, the Company, in good faith, may amend such
registration statement to exclude the Warrant Shares without otherwise
affecting the Registered Holder's rights to any other registration statement
herein. 

            (i) Primary Registrations. If a Piggyback Registration is an
    underwritten primary registration on behalf of the Company, and if the
    underwriter thereof advises the Company in writing that in its opinion the
    number of Warrant Shares requested to be included in such registration
    statement exceeds the number that can be sold in such offering without
    materially adversely affecting the distribution of such securities by the
    Company, then the Company will include in such registration statement first,
    the securities that the Company proposes to sell and second, the securities
    requested to be included in such registration statement by selling
    securityholders, such rights to inclusion being apportioned pro rata among
    the Registered Holder and the other holders of any other securities
    requesting registration according to the market value of Warrant Shares and
    other securities requested to be registered.

            Notwithstanding the above, if any such underwriter shall advise the
Company in writing that the distribution of the Warrant Shares being included
in the registration statement concurrently with the securities being registered
by the Company would materially adversely affect the distribution of such
securities by the Company, then the Registered Holder shall delay its offering
and sale for such period ending on the earliest of (a) one hundred eighty (180)
days following the effective date of the Company's registration statement, (b)
the earliest date that, in the opinion of such underwriter, such adverse effect
would no longer be caused, or (c) such date as the Company, managing
underwriter and Registered Holder shall otherwise agree. In the event of such
delay, the Company shall file such supplements and post-effective amendments
and take any such other actions as may be necessary or appropriate to permit
such Registered Holder to make its proposed offering and sale for a period of
at least ninety (90) days commencing immediately following the end of such
period of delay. If any party




                                     - 6 -
<PAGE>   41
          disapproves of the terms of any such underwriting, it may elect
          to withdraw therefrom by written notice to the Company, the
          underwriter and the Registered Holder. Notwithstanding the foregoing,
          the Company shall not be required to include Warrant Shares within the
          coverage of a registration statement being filed pursuant to this
          Section 9(a)(i) if, in the opinion of counsel for both the Company and
          Registered Holder, all of the Warrant Shares proposed to be registered
          may be immediately transferred pursuant to the provisions of Rule 144
          under the Securities Act.

               (ii) Priority on Secondary Registrations. If a Piggyback
          Registration is an underwritten secondary registration on behalf of
          holders of securities of the Company, and the underwriter thereof
          advises the Company in writing that in its opinion the number of
          Warrant Shares requested to be included in such registration statement
          exceeds the number of which can be sold in such offering without
          materially adversely affecting the distribution of such securities,
          then the Company will include in such registration statement the
          securities requested to be included in such registration statement by
          selling securityholders on a pro rata basis, with such rights to
          inclusion being apportioned among the Registered Holder and the other
          holders of any other securities requesting registration according to
          the market value of Warrant Shares and other securities requested by
          them, respectively, to be registered. Notwithstanding the foregoing,
          the Company shall not be required to include Warrant Shares within the
          coverage of a registration statement being filed pursuant to this
          Section 9(a)(ii) if, in the opinion of counsel for both the Company
          and Registered Holder, all of the Warrant Shares proposed to be
          registered may be immediately transferred pursuant to the provisions
          of Rule 144 under the Securities Act.

            (b) If at any time after June 18, 1997 and prior to the third (3rd)
     anniversary of the earlier of the Expiration Date and the exercise of the
     final Warrant represented hereby and the Warrant Shares issued or issuable
     upon exercise of the Warrants represented hereby are not then registered
     under one or more Piggyback Registrations and then covered by a prospectus
     complying with the requirements of the Securities Act, the Registered
     Holder may by written notice to the Company required the Company to file a
     registration statement under the Securities Act covering such Warrant
     Shares as the Registered Holder may specify in such notice. A Registered
     Holder shall be entitled so to require the Company to file a registration
     statement pursuant to this Section 9(b) on only one (1) occasion. The
     Company will file such a registration statement within ninety (90) days of
     receipt of such notice; and thereafter will prosecute such registration
     statement diligently to effectiveness; will cause such registration
     statement to become effective as promptly as practicable; will promptly
     file all such

supplements and post-effective amendments to such registration statement and
take any such other actions as may be necessary or appropriate to make
available to Registered Holder on as continuous a basis as is practicable a
prospectus meeting the requirements of the Securities Act through the earliest
of (a) the date on which the final Warrant Shares have been sold and
distributed by Registered Holder, (b) the date on which, in the opinion of
counsel for both the Company and Registered Holder, all of the Warrant Shares
which Registered Holder then holds may be immediately transferred pursuant to
the provisions of Rule 144 under the Securities Act, and (c) April 30, 2002;
and will register or qualify the securities so being registered under such
state and provincial securities or "blue sky" laws as the Registered Holder may
reasonably request.  In that regard, the Company makes no representative or
warranties as to its ability to have any registration statement or
post-effective amendment thereto declared effective.

     (c)  In the event of any registration of a security pursuant to this
Section 9, the Company shall indemnify the Registration Holder and its officers,
directors and other controlling persons against all losses, claims, damages and
liabilities caused by any untrue statement or alleged untrue statement of a
material fact contained in any registration statement or prospectus (and as
amended or supplemented) relating to such registration, or caused by any
omission or alleged omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances under which they are made unless such statement or omission
was made in reliance upon and in conformity with information furnished to the
Company by the Registered Holder expressly for use therein.  The Registered
Holder shall also indemnify the Company, its officers and directors and each
underwriter of the Warrant Shares so registered with respect to losses, claims
damages and liabilities caused by any untrue statement or omission made in
reliance upon and in conformity with information furnished by the Registered
Holder to the Company in writing expressly for use in such registration
statement or prospectus.

     (d)  All expenses of any registration referred to in this Section 9,
except the fees and disbursements of counsel to the Registered Holder,
underwriting commissions or discounts and any transfer or other taxes
applicable to the transfer of Warrant Shares by the Registered Holder, shall be
borne by the Company.

     (e)  Following the exercise of Warrants hereunder and the disposition of
Warrant Shares, the Registered Holder shall promptly advise the Company when
Registered Holder no longer holds any Warrant Shares acquired through the
exercise of Warrants hereunder, and upon the request of the Company, the
Registered Holder shall advise the Company from time to time of the number of
Warrant Shares then held by Registered Holder.

     (f)  The registration rights granted hereunder to the Registered Holder
with respect to Warrant Shares shall also apply to any other shares of the
Company's




                                      -8-

Common Stock or other securities issued by the Company other than Warrants
which are then held by the Registered Holder and constitute "restricted
securities" as that term is defined in Rule 144 promulgated under the
Securities Act, on the same basis as if such securities were Warrant Shares.

         10.      Notices. All notices, demands, elections, or requests (however
                  characterized or described) required or authorized hereunder

and discharge well and faithfully the responsibilities which may be assigned to

activities are in compliance with applicable securities laws and regulations.

required hereunder.  Although no specific hours-per-day requirement will be
required, Consultant and the Company agree that Consultant will perform the
duties set forth hereinabove in a diligent and professional manner.  The parties
acknowledge and agree that a disproportionately large amount of the effort to be
expended and the costs to be incurred by the Consultant and the benefits to be
received by the Company are expected to occur upon and shortly after, and in any
event, within one month of the effectiveness of this Agreement.  It is
explicitly understood that Consultant's performance of its duties hereunder will

by the Consultant.  It is also understood that the Company is entering into this
Agreement with Liviakis Financial Communications, Inc. ("LFC"), a corporation
and not any individual member of LFC, and with such, Consultant will not be
deemed to have breached this Agreement if any member, officer or director of LFC

activities during the term of the Agreement, provided the Consultant otherwise
performs its obligations under this Agreement.

this Agreement, the Company shall compensate Consultant as follows:

4.1     In connection with Consultant undertaking this engagement, the Company
      agrees to sell, and Consultant and Robert B. Prag ("RBP"), an affiliate
      of consultant, severally agree to buy, for One Canadian Dollar (C$1.00)
      per unit five hundred thousand (500,000) units (the "Units"), each
      consisting of one share of the Company's common stock ("Common Stock")
      and one stock purchase warrant (a "Warrant") entitling the holder thereof
      to purchase a share of Common Stock at an exercise price of One Dollar
      and Ten Cents Canadian (C$1.10) through November 7, 2001.  The Warrants
      shall be evidenced by the form of warrant certificate attached hereto as
      Exhibit A. It is understood that the Units, the shares of Common Stock
      and Warrants constituting the Units, and the shares of Common Stock
      issuable upon exercise of the Warrants have not been registered under the
      Securities Act of 1933, as amended (the "Securities Act"), and 
      consequently such securities constitute and will constitute "restricted
      securities" as defined in Rule 144 promulgated under the Securities Act,
      unless registered under the Securities Act.

        Consultant shall purchase three hundred seventy-five thousand (375,000)
      Units, for which he shall deliver to the Company his promissory note in
      the amount of Two Hundred Eighty-One Thousand Two Hundred Fifty United
      States Dollars (US$281,250), payable in four monthly installments on the
      fifteenth (15th) day of December 1996 and January, February and March
      1997 of US$56,250, US$75,000, US$75,000 and US$75,000, respectively.  RBP
      shall purchase one hundred twenty-five thousand (125,000) Units, for which
      he shall deliver to the Company his promissory note in the amount of 
      Ninety-Three Thousand Seven Hundred Fifty United States Dollars
      (US$93,750), payable in four monthly installments on the fifteenth (15th)
      day of December 1996 and January, February and March 1997 of US$18,750,
      US$25,000, US$25,000, and US$25,000 respectively.  Certificates
      representing the shares of Common Stock and Warrants constituting the
      Units shall be issued in the names of Consultant and RBP and delivered in
      trust to Weir & Foulds, counsel to the Company, pursuant to irrevocable
      instructions under which Weir & Foulds is to deliver the certificates
      representing such securities to Consultant and RBP, respectively, pro
      rata as such promissory notes are paid.

        In addition, as consideration for Consultant undertaking this 
      engagement, the Company shall issue and deliver to Consultant an aggregate
      of one million four hundred ninety thousand (1,490,000) shares (the 
      "Consideration Shares") of Common Stock.  The Consideration Shares shall 
      be issued by the Company and delivered to Consultant in accordance with 
      the following schedule:

     It is understood that the Consideration Shares have not been registered
   under the Securities Act and consequently such securities constitute and will
   constitute "restricted securities" as defined in Rule 144 promulgated under
   the Securities Act, unless registered under the Securities Act.

     The Company agrees that, when issued and delivered to Consultant and RBP,
   the Consideration Shares, the shares of Common Stock constituting part of the
   Units and the shares of Common Stock issuable upon exercise of the Warrants
   shall be duly authorized, validly outstanding, fully paid and non-assessable.
   The Company also understands and agrees that Consultant has foregone
   significant opportunities to accept this engagement and that the Company
   derives substantial benefit from the execution of this Agreement and the
   ability to announce its relationship with Consultant. The Consideration
   Shares, therefore, constitute payment for Consultant's agreement to represent
   the Company and are a nonrefundable, non-apportionable and non-ratable
   retainer.  If the Company elects to terminate this Agreement prior to January
   2, 1998 for any reason whatsoever, it is agreed and understood that
   Consultant will not be and may not be required or requested by the company to
   return any of the Consideration Shares or any securities constituting the
   Units or issued upon exercise of the Warrants.
   
     The Consideration Shares and the shares of Common Stock constituting the 
   Units shall have the benefit of the same registration rights as the shares of
   Common Stock issuable upon exercise of the Warrants receive pursuant to the
   terms of the warrant certificates representing the Warrants.  The Company
   agrees to file by November 30, 1997 and thereafter to prosecute diligently to
   effectiveness a registration statement under the Securities Act covering,
   among other securities, such Consideration Shares, shares of common Stock
   constituting part of the Units, and shares of Common Stock issuable upon
   exercise of the Warrants as Consultant and RBP may request.  Consultant and 
   RBP agree that they, respectively, will not sell shares of Common Stock 
   received hereunder prior to January 2, 1998.
   
4.2  Consultant and Prag (hereinafter referred to as "Consultants") acknowledge
   that the shares of Common Stock, the Options and the shares issuable upon the
   exercise of the Options to be issued pursuant to this Agreement 
   (collectively, the "Shares") have not been registered under the Securities 
   Act of 1933, and accordingly are "restricted securities" within the meaning
   of Rule 144 of the Act.  As such, the Options and the Shares may not be
   resold or transferred unless the Company has received an opinion of counsel
   reasonably satisfactory to the Company that such resale or transfer is
   exempt from the registration requirements of that Act.

4.3   In connection with the acquisition of Shares hereunder, the Consultants
   represent and warrant to the Company as follows:

      (a) Consultants acknowledge that the Consultants have been afforded the
   opportunity to ask questions of and receive answers from duly authorized
   officers or other


                                       4.
<PAGE>   5
    representatives of the Company concerning an investment in the Shares,
    and any additional information which the Consultants have requested.

      (b)  Consultants' investment in restricted securities is reasonable in
    relation to the Consultants' net worth, which is in excess of ten (10) times
    the Consultants' cost basis in the Shares.  Consultants have had experience
    in investments in restricted and publicly traded securities, and
    Consultants have had experience in investments in speculative securities
    and other investments which involve the risk of loss of investment.
    Consultants acknowledges that an investment in the Shares is speculative
    and involves the risk of loss.  Consultants have the requisite knowledge to
    assess the relative merits and risks of this investment without the
    necessity of relying upon other advisors, and Consultants can afford the
    risk of loss of his entire investment in the Shares. Consultants are (i)
    accredited investors, as that term is defined in Regulation D promulgated
    under the Securities Act of 1933, and (ii) a purchaser described in Section
    25102(f)(2) of the California Corporate Securities Law of 1968, as
    amended.
    
      (c)   Consultants are acquiring the Shares for the Consultants' own
    account for long-term investment and not with a view toward resale or 
    distribution thereof except in accordance with applicable securities laws.

      (d)   In any vote of shareholders for the election of directors or any
    related matter (such as increasing or decreasing the authorized number of
    directors or creating a classified board of directors) held prior to
    January 1, 2001, Consultants shall vote any shares of Common Stock received
    by Consultants pursuant to this Agreement, either directly or through the
    exercise of warrants, and then held by Consultants (i) in connection with
    the election of directors for such nominees as may be designated by Eugene
    A. Soltero and James E. Houge and (ii) with respect to related matters in
    such manner as Messrs. Soltero and Houge may designate.  Any designation
    regarding voting by Messrs. Soltero and Houge shall be made in a written
    notice executed by Messrs. Soltero and Houge and delivered to Consultants. 
    It is understood that any shares of Common Stock transferred by Consultants
    to person or entities not subject to the control of Consultants shall be
    transferred free of any obligation with respect to voting arising under
    this subparagraph.
    
5.    Financing "Finder's Fee".  It is understood that in the event Consultant
    introduces Company, or its nominees, to a lender or equity purchaser, not
    already having a preexisting relationship with the Company, who Company, or
    its nominees, ultimately finances or causes the completion of such 
    financing, Company agrees to compensate Consultant for such services with a
    "finder's fee" in the amount of 2.5% of total gross financing provided by
    Company payable in cash.  This will be in addition to any fees payable by
    Company to any other intermediary, if any, which shall be per separate
    agreements negotiated between Company and such other intermediary.

5.1   It is further understood that Company, and not Consultant, is responsible
    to perform any and all due diligence on such lender or equity purchaser 
    introduced to it by Consultant under this Agreement, prior to Company 
    receiving funds.  However, Consultant will not introduce any parties to 
    Company about which Consultant has any prior knowledge of questionable, 
    unethical or illicit activities.

5.2   Company agrees that said compensation to Consultant shall be paid in full
    at the time said financing is closed. Moreover, said compensation, will be
    a condition precedent to the closing of such or financing and Company shall
    execute any and all documents necessary to effect said compensation.

5.3   As further consideration to Consultant, Company, or its nominees, agrees
    not to obtain any other financing from any lender or equity purchaser
    supplied or referred to Company by Consultant for a period of five years
    from the date of this Agreement, either directly or indirectly through
    third parties or nominees.  In the event of circumvention by Company, or
    its nominees, Consultant shall receive a fee equal to that outlined in
    Section "5" herein.

5.4   Consultant will notify Company of introductions it makes for potential
    sources of financing in a timely manner (approximately 3 days within
    introduction) via facsimile memo.  If Company has a preexisting
    relationship with such nominee and believes such party should be excluded
    from this Agreement, then Company will notify Consultant immediately of
    such circumstance via facsimile memo.

6.    Expenses.  Consultant agrees to pay for all its expenses (phone, mailing,
    labor, etc.), other than extraordinary items (travel required by/or
    specifically requested by the Company, luncheons or dinners to large groups
    of investment professionals, mass faxing to a sizable percentage of the
    Company's constituents, investor conference calls, print advertisements in
    publications, etc.) approved by the Company prior to its incurring an
    obligation for reimbursement.

7.    Indemnification. The Company warrants and represents that all oral
    communications, written documents or materials, other than those designated
    by the Company to the Consultant as "confidential" or "Company private",
    furnished to Consultant by the Company with respect to financial affairs,
    operations, profitability and strategic planning of the Company are accurate
    and Consultant may rely upon the accuracy thereof without independent
    investigation.  The Company will protect, indemnify and hold harmless
    Consultant against any claims or litigation including any damages,
    liability, cost and reasonable attorney's fees with respect thereto
    resulting from Consultant's communication or dissemination of any said
    information, documents or materials not designated by the Company to the
    Consultant as "confidential" or "Company private", excluding any such claims
    or litigation resulting from Consultant's communication or dissemination of
    information not provided or authorized by the Company.  To the extent
    feasible, the Company agrees to make Consultant an additional insured on any
    and all commercial liability and directors and officers liability insurance
    policies and to provide Consultant with current Certificates of Insurance
    reflecting the same.

                      CONVERTIBLE SECURED PROMISSORY NOTE


$1,000,000                                               Los Angeles, California
                                                                   June 24, 1997


          FOR VALUE RECEIVED, the undersigned, COTTON VALLEY RESOURCES 
CORPORATION (hereinafter referred to as "Borrower"), promise(s) to pay to the
order of LIVIAKIS FINANCIAL COMMUNICATIONS, INC. ("Lender"), at 2420 "K" Street,
Suite 220, Sacramento, California 95816, or at any other place that may be
designated in writing by Lender, on or before the Maturity Date (hereinafter
defined), the sum of One Million Dollars ($1,000,000) or so much thereof as may
have been advanced hereunder, whichever is lesser, with interest thereon at the
rate of nine percent (9%) per annum until paid in full.  All sums are due and
payable in lawful money of the United States of America.

     1.  Security.  This Secured Promissory Note (the "Note") will be, and upon
execution hereof is, secured by a Security Agreement, of even date herewith.

     2.  Payments.   Each payment under this Note shall be credited first to
any and all costs and expenses to enforce this Note, then to interest then due
and the remainder to the reasonably unpaid principal.

     3.  Prepayment.  Borrower shall have the right to make payments at any
time and from time to time without penalty or premium, to be applied to all or
any portion of the balance due under this Note.

     4.  Maturity Date.  The Maturity Date for this Note, when the outstanding
principal balance and all interest accrued thereon shall be due and payable, is
October 24, 1997, unless extended at the instance and request of Borrower as
herein after set forth.  In the event Borrower fails to close and receive the
resulting funds from a private placement of Borrower's equity securities in the
amount of $1,000,000 or more prior to October 24, 1997, Borrower, upon written
notice to Lender, may extend the Maturity date to November 24, 1997.

     5.  Advances.  Upon the execution hereof, Lender shall immediately loan
and advance to Borrower by wire transfer the amount of $579,000.00.
Subsequently, during the term of this Note and at the request of Borrower,
Lender, without being obligated to approve such request, may loan and advance
to Borrower an additional amount or amounts which in the aggregate shall not
exceed $421,000.00.
<PAGE>   2
     6.  Waivers.  Borrower waives diligence, presentment and protest, and also
waives notice of protest, dishonor and nonpayment of this Note and expressly
agrees that this Note or any payment due hereunder may be extended from time to
time, and consents to the acceptance of further security or release of any
security for this Note, all without in any way affecting Borrower's liability
under this Note, even if Borrower is not a party to such agreement.

     7.  Costs and Expenses.  In addition to all other sums due hereunder,
Borrower shall be obligated to pay:

         (a)     All costs and expenses of collection, including, without
limitation, reasonable attorneys' fees, if this Note or any other instrument,
agreement, or document executed in connection with, or securing, Lender's
payment of this Note is placed in the hands of an agent for collection or
enforcement and such collection or enforcement is commenced without legal
proceeding; and

         (b)     All costs and expenses, including, without limitation,
reasonable attorneys' fees, incurred by Lender in connection with any
bankruptcy, insolvency, or reorganization proceeding or receivership involving
Borrower including, without limitation, reasonable attorneys' fees incurred in
making any appearance in any such proceeding or in seeking relief from any stay
or injunction issued in or arising out of any such proceeding.

     8.  Maximum Rate.  This Note is subject to the express condition that at
no time shall Borrower be obligated or required to pay interest on the principal
balance of this Note at a rate which could subject Lender either to civil or
criminal penalty as a result of interest being in excess of the maximum rate
which Borrower is permitted by law to contract or agree to pay. If, by the terms
of this Note, Borrower at any time is required or obligated to pay interest on
the principal balance of this Note at a rate in excess of the maximum rate, then
the rate of interest under this Note shall be deemed to be immediately reduced
to the maximum rate and interest payable hereunder shall be computed at the
maximum rate and any prior interest payments made in excess of the maximum rate
shall be applied and shall be deemed to have been payment made in reduction of
the principal balance of this Note.

     9.  Unconditional Obligation.  Borrower acknowledges that this Note and
Borrower's obligations under this Note are and shall at all times continue to be
absolute and unconditional in all respects, and shall at all times be valid and
enforceable irrespective of any other agreements or circumstances of any nature
whatsoever which might otherwise constitute a defense to this Note and the
obligations of Borrower under this Note or the obligations of any other person
or party relating to this Note.


                                       2

         10.     Compliance with Covenants. Borrower shall perform and comply
with each of the covenants, conditions, provisions, and agreements contained in
every agreement or instruments now evidencing or securing the indebtedness
represented by this Note.

         11.      Conversion.  This Note shall be convertible into Common Stock
of Borrower as follows:

                  (a)     Subject to and upon compliance with the provisions of
this Section 11, Lender shall have the right at his option, at any time or from
time to time during the term of this Note, to convert all or any part of this
Note into shares of Common Stock of Borrower.  The number of shares issuable
upon conversion of all or part of this Note shall be determined by dividing the
principal and accrued but unpaid interest to be converted by the then
applicable Conversion Price.  The Conversion Price shall be One Dollar and
Sixty-Six and 2/3 Cents (US$1.66 2/3), subject to adjustment as provided
herein.

                  (b)     Lender may exercise the conversion right specified in
Section 11(a) by delivering to Borrower a written notice, specifying the amount
of the Note to be converted and providing representations regarding compliance
with applicable securities laws and regulations.  Conversion shall be deemed to
have been effected on the date when such written notice of an election to
convert is received by Borrower, and such date is referred to herein as the
"Conversion Date".  As promptly as practicable thereafter, Borrower shall issue
and deliver to or upon the written order of Lender a certificate or
certificates for the number of full shares of Common Stock to which Lender is
entitled and a check or cash with respect to any fractional interest in a share
of Common Stock as provided in Section 11(c) hereof.  The person in whose name
the certificate or certificates for Common Stock are to be issued shall be
deemed to have become a holder of record of such Common Stock on the applicable
Conversion Date.  Upon conversion of only a portion of this Note, the amount of
any such conversion shall be deemed a principal payment hereon.  Upon
conversion of all of this Note, the Note shall be marked "PAID" and returned to
Borrower, and Lender shall release any and all collateral securing this Note.

                  (c)     No fractional shares of Common Stock or scrip shall 
be issued upon conversion of any portion of this Note.  Instead of any
fractional shares of Common Stock which would otherwise be issuable upon
conversion of any portion of this Note, Borrower shall pay a cash adjustment in
respect of such fractional interest in an amount equal to that fractional
interest of the Conversion Price.

                  (d)     The number of shares of Common Stock issuable upon 
conversion of this Note shall be subject to adjustment from time to time as
follows:



                                       3
<PAGE>   4
                 (i)      Stock Splits, Stock-Combinations and Certain Stock
         Dividends.  If Borrower shall at any time subdivide or combine its
         outstanding shares of Common Stock, or declare a dividend in Common
         Stock or other securities of Borrower convertible into or exchangeable
         for Common Stock, this Note shall, after such subdivision or 
         combination or after the record date for such dividend, be convertible
         for that number of shares of Common Stock and other securities of
         Borrower that the Lender would have owned immediately after such event
         with respect to the Common Stock and other securities into which this
         Note may have been converted immediately before such event had this
         Note been converted immediately before such event.  Any adjustment
         under this Section 11(d) shall become effective at the close of
         business on the date the subdivision, combination or dividend becomes
         effective.

                 (ii)     Adjustment for Reorganization, Consolidation, Merger.
         In case of any reorganization of Borrower (or any other corporation
         the stock or other securities of which are at the time receivable upon
         conversion of this Note) or in case Borrower (or any such other
         corporation) shall merge into or with or consolidate with another
         corporation or convey all or substantially all of its assets to
         another corporation or enter into a business combination of any form
         as a result of which the Common Stock or other securities receivable
         upon conversion of this Note are converted into other stock or
         securities of the same or another corporation, then and in each such
         case, Lender, upon exercise of the conversion right at any time after
         the consummation of such reorganization, consolidation, merger,
         conveyance or combination, shall for the same Conversion Price be
         entitled to receive, in lieu of the Shares or other securities to
         which such Lender would have been entitled had he exercised the
         conversion right immediately prior thereto, such stock and securities
         which Lender would have owned immediately after such event with
         respect to the Common Stock and other securities for which this Note
         may have been converted immediately before such event had this Note
         been converted immediately prior to such event.

         In each case of an adjustment in the Common Stock or other securities
receivable upon the conversion of this Note, Borrower shall promptly notify
Lender of such adjustment.  Such notice shall set forth in reasonable detail
the facts upon which such adjustment is based.

         12.     Dispute Resolution.  Texas law shall govern the construction,
interpretation, validity and enforcement of this Note.  If any legal action or
any arbitration or other proceeding is brought for the enforcement or
interpretation of this Note, or because of an alleged dispute, breach, default
or misrepresentation, in connection with or related to this Note, the
prevailing party shall be entitled to recover reasonable attorneys' fees and
other costs in connection with that action or proceeding, in addition to any
other relief to which it may be entitled.  As used in this Note, the
"prevailing

party" is the person awarded greater relief in the action, arbitration or
proceeding.  This paragraph is and is intended to be severable from the 
remaining provisions of this Note, and shall survive any judgment awarded under
this Note and shall not be merged into any such judgment.

                               SECURITY AGREEMENT

         THIS SECURITY AGREEMENT (this "Agreement") is entered into as of June
24, 1997 by and among COTTON VALLEY RESOURCES CORPORATION, a corporation
incorporated under the laws of Ontario, Canada (the "Borrower"), and COTTON
VALLEY ENERGY, INC., an Oklahoma corporation, (the Pledgor") a wholly-owned
subsidiary of Borrower and LIVIAKIS FINANCIAL COMMUNICATIONS, INC. (the
"Secured Party").

                                    RECITALS

         Concurrently herewith, Borrower has executed a certain Convertible
Secured Promissory Note of even date herewith in the amount of One Million
Dollars ($1,000,000) in favor of Secured Party (the "Note"). In order to secure
prompt payment and performance in full under the Note and other instruments
evidencing the obligation of Borrower to Secured Party, Pledgor has agreed to
grant Secured Party certain security interests as described herein.

         It is a condition to the consummation of the transaction evidenced by
the Note that Borrower, Pledgor and Secured Party shall have undertaken the
obligations contemplated by this Agreement.

         NOW, THEREFORE, in consideration of the above and in order to induce
Secured Party to enter into the transaction evidenced by the Note with
Borrower, Secured Party, Borrower and Pledgor hereby agree as follows:

                                   AGREEMENT

         1.      Certain Defined Terms. Terms used and not otherwise defined
herein have the respective meanings assigned to them in the Note.

         2.      Security Interest. Pledgor hereby assigns and grants to Secured
Party for its benefit a security interest in all of Pledgor's right, title and
interest of every kind or nature whatsoever without limitation in and to (but
none of its obligations with respect to) all its assets in the N. E. Alden
Field, Caddo County, Oklahoma, which are listed on Exhibit A hereto, including
all products and proceeds thereof (the "Collateral").


                                      1
<PAGE>   2
         3.      Security for Obligations. This Agreement secures, and the
Collateral is collateral security for Borrower's obligations under the Note.
All such obligations of Borrower are referred to herein as the "Secured
Obligations."

         4.      Financing Statements. At any time and from time to time, upon
request of Secured Party, Pledgor will give, execute, file and/or record any
notice, financing statement, continuation statement, instrument, document or
agreement that Secured Party may consider necessary or desirable to create,
preserve, continue, perfect or validate any security interest granted hereunder
or which Secured Party may consider necessary or desirable to exercise or
enforce its rights hereunder with respect to such security interest.

         5.      Representations and Warranties.   Borrower and Pledgor,
jointly and severally, represent and warrant to Secured Party as follows:

                 (a)      Pledgor owns all of the Collateral free and clear of
any lien, security interest, preferential arrangement or other charge or
encumbrance (collectively, a "Lien") except for the security interest created
by this Agreement.

                 (b)      Borrower and Pledgor have full power and lawful
authority to enter into this Agreement; and Pledgor has full power and
authority to assign and grant to Secured Party a first priority security
interest in the Collateral as herein provided; the execution, delivery and
performance hereof are not in contravention of any indenture, agreement or
undertaking to which Borrower or Pledgor is a party or by which Pledgor or its
property is bound; and this Agreement constitutes the legally valid and binding
obligation of Borrower and Pledgor enforceable against Borrower and Pledgor in
accordance with its terms, subject, as to enforcement, to bankruptcy,
insolvency, reorganization, moratorium, and other similar laws of general
applicability relating to or affecting creditors' rights generally and to
equitable principles relating to enforceability.

                 (c)      No consent of any other party (including, without
limitation, creditors of Borrower or Pledgor) and no consent, authorization,
approval or other action by, and no notice to or filing with, any governmental
authority or regulatory body is required either (i) for the grant by Pledgor of
the security interest granted hereby or for the execution, delivery or
performance of this Agreement by Borrower and Pledgor or (ii) for the exercise
by Secured Party of the rights provided for in this Agreement or the remedies
in respect of the Collateral pursuant to this Agreement, except for the filing
of any UCC Financing Statements.


                                       2
<PAGE>   3
                 (d)      This Agreement creates a valid and perfected first
priority security interest in the Collateral, unless otherwise consented to in
writing by Secured Party securing the payment of the Secured Obligations, upon
the filing of UCC Financing Statements and the taking of such other actions as
are necessary or desirable to perfect and protect the security interest granted
hereby.

         6.      Certain Covenants. Pledgor hereby covenants that, until the
Secured Obligations have been terminated in accordance with the Note, Pledgor
will:

                 (a)      not (i) sell, assign (by operation of law or
otherwise) or otherwise dispose of, or grant any interest with respect to, any
of the Collateral or (ii) create or permit to exist any Lien upon or with
respect to any of the Collateral, except for the security interest created
under this Agreement;

                 (b)      promptly notify Secured Party of any event of which
Pledgor becomes aware causing material and unusual loss or depreciation in the
value of the Collateral;

                 (c)      promptly deliver to Secured Party copies of all
written notices received by it with respect to the Collateral which have a
material, adverse effect on the Collateral; and

                 (d)      pay or discharge, prior to delinquency, all taxes,
charges, fees, expenses, Liens and assessments of every nature levied or
imposed upon the Collateral.

         7.      Further Assurances. Pledgor agrees that at any time and from 
time to time, at the expense of Pledgor, Pledgor will promptly execute and
deliver all further instruments and documents, and take all further actions,
that may reasonably be necessary or desirable, or that Secured Party may
request, in order to perfect and protect any security interest granted or
purported to be granted hereby or to enable Secured Party to exercise and
enforce its rights and remedies hereunder with respect to any Collateral.

         8.      Secured Party May Perform. If Borrower or Pledgor fail to
perform any agreement contained herein, Secured Party may itself perform, or
cause performance of, such agreement, and the expenses of Secured Party
incurred in connection therewith shall be payable by Borrower under Section
13(b).


                                       3
<PAGE>   4
         9.      Standard of Care. The powers conferred on Secured Party
hereunder are solely to protect its interest in the Collateral and shall not
impose on it any duty to exercise such powers. Pledgor and Secured Party shall
each be deemed to have exercised reasonable care in the custody and
preservation of any Collateral in their possession if such Collateral is
accorded treatment substantially equivalent to that rendered by a reasonably
prudent operator of oil and gas properties. Neither Pledgor nor Secured Party
shall have any responsibility for (a) taking any necessary steps (other than
steps taken in accordance with the standard of care set forth above to maintain
possession of the Collateral) to preserve rights against any parties with
respect to any Collateral, (b) taking any necessary steps to collect or realize
upon the Secured Obligations or any guarantee therefor, or any part thereof; or
any of the Collateral, or (c) initiating any action to protect the Collateral
against the possibility of a decline in value.

         10.      Events of Default. The occurrence of the following
shall be an "Event of Default" under this Agreement: Borrower's breach of its
obligations to Secured Party under the Note and such breach continues for (i)
ten (10) days with respect to a payment default, and (ii) thirty (30) days with
respect to a non-payment default, after Borrower's and Pledgor's receipt of
written notice thereof.

         11.      Remedies Upon Default. If any Event of Default shall
have occurred and be continuing, Secured Party may exercise in respect of the
Collateral, in addition to other rights and remedies provided for herein or
otherwise available to it, all the rights and remedies of a secured party on
default under the Commercial Code as in effect in the State of Oklahoma (or any
other state with jurisdiction over the Collateral) at that time, and Secured
Party may also in its sole discretion, without notice (except as specified
below), sell the Collateral or any part thereof in one or more parcels at
public or private sale, at any exchange, broker's board or any of Secured
Party's offices or elsewhere, for cash, on credit or for future delivery, at
such time or times and at such price or prices and upon such other terms as
Secured Party may deem commercially reasonable, irrespective of the impact of
any such sales on the market price of the Collateral. Secured Party may be the
purchaser of any or all of the Collateral at any such sale and shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Collateral sold at any such public
sale, to use and apply any of the Secured Obligations as a credit on account of
the purchase price of any Collateral payable by Secured Party at such sale.
Each purchaser at any such sale shall hold the property sold absolutely free
from any claim or right on the part of Pledgor, and Pledgor hereby waives (to
the extent permitted by law) all rights of redemption, stay and/or appraisal
which it now has or may at any time in the future have under any rule of law or
statute now existing or hereafter enacted. Pledgor agrees that, to the extent
that notice of sale shall be required by law, at least ten days' notice to
Pledgor of the time and place of any public sale or the time after which any
private sale is to be made shall constitute reasonable notification. Secured
Party shall

                                       4
<PAGE>   5
not be obligated to make any sale of Collateral regardless of notice of sale
having been given. Secured Party may adjourn any public or private sale from
time to time by announcement at the time and place fixed therefor, and such
sale may, without further notice, be made at the time and place to which it was
so adjourned. Pledgor hereby waives any claims against Secured Party arising by
reason of the fact that the price at which any Collateral may have been sold at
such a private sale was less than the price which might have been obtained at a
public sale, even if Secured Party accepts the first offer received and does
not offer such Collateral to more than one offeree. If the proceeds of any sale
or other disposition of the Collateral are insufficient to pay all the Secured
Obligations, Borrower shall be liable for the deficiency and the reasonable
fees of any attorneys employed by Secured Party to collect such deficiency.

         12.     Application of Proceeds. All Proceeds received by Secured
Party in respect of any sale of, collection from, or other realization upon all
or any part of the Collateral may, in the discretion of Secured Party, be held
by Secured Party as Collateral for, and/or then or at any time thereafter
applied in whole or in part by Secured Party against the Secured Obligations in
the following order of priority:

         FIRST: To the payment of the costs and expenses of such sale,
collection or other realization, and all expenses, liabilities and advances
made or incurred by Secured Party in connection therewith, including reasonable
compensation to Secured Party and his agents and counsel, in accordance with
Section 13(b);

         SECOND: To the payment in full of all Secured Obligations in such
order as Secured Party shall elect; and

         THIRD: To the payment to or upon the order of Borrower or Pledgor, or
to whosoever may be lawfully entitled to receive the same or as a court of
competent jurisdiction may direct, of any surplus then remaining from such
proceeds.

         13.     Indemnity and Expenses.

         (a)     Borrower, and where the claim, loss, liability, cost or
expense incurred by Secured Party arises out of or in connection with the
pledge of the Collateral herein by Pledgor, joined herein by Pledgor, agree to:
indemnify Secured Party from and against any and all claims, losses and
liabilities in any way relating to, growing out of or resulting from this
Agreement and the transactions contemplated hereby (including, without
limitation, enforcement of this Agreement), except claims, losses or
liabilities resulting from Secured Party's (i) breach of this agreement, (ii)
gross negligence or (iii) willful misconduct;

         (b)     Upon the occurrence of an Event of Default pay to Secured
Party the amount of any and all costs and expenses, including the reasonable
fees and expenses


                                       5
<PAGE>   6
incurred in connection with (i) the administration of this Agreement, (ii) the
custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Collateral, (iii) the exercise or enforcement of
any of the rights of Secured Party hereunder, or (iv) the failure by Borrower
to perform or observe any of the provisions hereof; and

         (c)     Indemnify and hold harmless Secured Party and its directors,
officers, employees, affiliates, agents and assigns, from and against any and
all losses of Secured Party directly or indirectly, as a result of, or based
upon or arising from any inaccuracy in or breach or nonperformance of any of
the representations, warranties, covenants or agreements made by Borrower in or
pursuant to this Agreement or the Note.

         14.     Waivers. Borrower, and where applicable as a result of or in
connection with the pledge of the Collateral herein by Pledgor, joined herein
by Pledgor, agree to:

         (a)     Except as otherwise required by the Note or this Agreement,
waive any right to require Secured Party to (i) proceed against Borrower, any
guarantor of any of the Secured Obligations or any other person or entity; (ii)
proceed against or exhaust any other security held from any other person or
entity; (iii) give notice to Borrower of the terms, time and place of any
public or private sale or the Collateral or any other security, or otherwise
comply with the notice provisions of the Commercial Code as in effect in the
State of Oklahoma; (iv) pursue any other remedy in Secured Party's power; or
(v) make or give any presentments, demands for performance, notices of
nonperformance, protests, notices of protest or notices of dishonor in
connection with any obligations or evidences of indebtedness which constitute
in whole or in part the Secured Obligations or in connection with the creation
of new or additional Secured Obligations;

         (b)     Waive any defense arising by reason of: (i) any disability or
other defense of Borrower or any other entity, including, without limitation,
any defense based on or arising out of the unenforceability of any of the
Secured Obligations, legal or equitable discharge of the Secured Obligations or
this Agreement or any statute of limitations affecting Borrower's liability
hereunder or the enforcement hereof; (ii) the cessation from any cause
whatsoever, other than termination, of the Secured Obligations; (iii) any act
or omission by Secured Party which directly or indirectly results in or aids
the discharge of Borrower or any of the Secured Obligations by operation of law
or otherwise; (iv) the release of any other collateral securing the Secured
Obligations or the failure by Secured Party to perfect or maintain the
perfection of any such other collateral; (v) any modification of the Secured
Obligations, in any form whatsoever, including, but not limited to the renewal,
extension, acceleration or other change in the time for payment of the Secured
Obligations, and any change in the terms of the Secured Obligations; and (vi)
any law limiting the liability of or exonerating guarantors or sureties.



                                       6
<PAGE>   7
         (c)     Until all the Secured Obligations shall have terminated, waive
any right to enforce any remedy which Secured Party now has or may hereafter
have against Borrower and waives any benefit of, or any right to participate in
any security whatsoever now or hereafter held by Secured Party for the Secured
Obligations.

         15.     Continuing Security Interest. This Agreement shall create a
continuing security interest in the Collateral and shall (a) remain in full
force and effect until termination of all Secured Obligations, (b) be binding
upon Borrower, Pledgor, their successors and assigns, and (c) inure, together
with the rights and remedies of Secured Party hereunder, to the benefit of
Secured Party and its successors. Secured Party may not assign or otherwise
transfer this Agreement or the benefits hereunder to any other person or
entity. Upon the termination of all Secured Obligations, Pledgor shall be
entitled to the execution of UCC Termination Statements and the return upon its
request and at its expense, against receipt and without recourse to Secured
Party, of such of the Collateral in Secured Party's possession as shall not
have been sold or otherwise applied pursuant to the terms hereof.

         16.     No Waiver by Secured Party. No failure on the part of Secured
Party to exercise, and no course of dealing with respect to, and no delay in
exercising, any right, power or remedy hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise by Secured Party of any
right, power or remedy hereunder preclude any other or further exercise thereof
or the exercise of any other right, power or remedy. The remedies herein
provided are cumulative to the fullest extent permitted by law and are not
exclusive of any remedies provided by law.

         17.     Amendment, Etc. No amendment or waiver of any provision of
this Agreement, nor consent to any departure by Borrower or Pledgor herefrom,
shall in any event be effective unless the same shall be in writing and signed
by all parties to this Agreement, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.

         18.     Addresses for Notices. All notices and other communications
provided for hereunder shall be in writing (including telegraphic or telecopy
communications) and, if to any party, mailed, telegraphed, telecopied or
delivered to it, addressed to it at the address of such party specified in the
Note, or as to any party at such other address as shall be designated by such
party in a written notice to each other party complying as to delivery with the
terms of this Section 18. All such notices and other communications shall be
effective upon receipt.

         19.     Governing Law; Terms. This agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of Texas,
except as required by mandatory provisions of law and except to the extent that
the validity or

                                       7
<PAGE>   8
perfection of the security interest hereunder, or remedies hereunder, in
respect of any particular collateral are governed by the laws of a jurisdiction
other than the State of Texas.

         20.     Severability. Any provisions of this Agreement which are
prohibited or unenforceable in any jurisdiction shall, as to such
jurisdictions, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate
or render unenforceable such provision in any other jurisdiction.

         21.     Consent to Jurisdiction and Service of Process. All judicial
proceedings brought against Borrower with respect to this Agreement may be
brought in any state or federal court of competent jurisdiction in the State of
California, and by execution and delivery of this Agreement, Borrower accepts
for itself and in connection with its properties, generally and
unconditionally, the nonexclusive jurisdiction of the aforesaid courts, and
irrevocably agrees to be bound by any judgment rendered thereby in connection
with this Agreement. Borrower designates and appoints Eugene A. Soltero and Jim
E. Hogue and such other persons as may hereafter be selected by Borrower
irrevocably agreeing in writing to so serve, as its agent to receive on its
behalf service of all process in any such proceedings in any such court, such
service being hereby acknowledged by Borrower to be effective and binding
service in every respect. A copy of any such process so served shall be mailed
by registered mail to Borrower at its address referred to in Section 18, except
that unless otherwise provided by applicable law, any failure to mail such copy
shall not affect the validity of service of process. If any agent appointed by
Borrower refuses to accept service, Borrower hereby agrees that service upon it
by mail shall constitute sufficient notice. Nothing herein shall affect the
right to serve process in any other manner permitted by law or shall limit the
right of the Agent to bring proceedings against Borrower in the courts of any
other jurisdiction.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed and delivered as of the date first written above.

THE WARRANTS REPRESENTED BY THIS CERTIFICATE AND THE COMMON STOCK ISSUABLE UPON
EXERCISE OF THE WARRANTS HAVE NOT BEEN REGISTERED OR QUALIFIED UNDER THE
SECURITIES ACT OF 1933 OR THE SECURITIES OR BLUE SKY LAWS OF ANY STATE AND MAY

                      COTTON VALLEY RESOURCES CORPORATION

             Incorporated Under the Laws of the Province of Ontario

No. 97L-1                                                   161,351 Common Stock

                               PURCHASE WARRANTS

         1. Warrant. This Warrant Certificate certifies that LIVIAKIS FINANCIAL
COMMUNICATIONS, INC., or registered assigns (the "Registered Holder"), is the
registered owner of the above indicated number of Warrants expiring on the
Expiration Date, as hereinafter defined. One (1) Warrant entitles the
Registered Holder to purchase one (1) share of the common stock (a "Share") of
Cotton Valley Resources Corporation, an Ontario corporation (the "Company"),
from the Company at a purchase price of Two Dollars and Eight Cents (US$2.08)
(the "Exercise Price") at any time during the Exercise Period, as hereinafter
defined, upon surrender at the principal office of the Company of this Warrant
Certificate with the exercise form appended hereto duly completed and executed
and accompanied by payment of the Exercise Price.

         Upon due presentment for transfer or exchange of this Warrant
Certificate at the principal office of the Company, a new Warrant Certificate
or Warrant Certificates of like tenor and evidencing in the aggregate a like
number of Warrants shall be issued in exchange for this Warrant Certificate,
subject to the limitations provided herein, upon payment of any tax or
governmental charge imposed in connection with such transfer. Subject to the
terms hereof, the Company shall deliver Warrant Certificates in required whole
number denominations to Registered Holders in connection with any transfer or
exchange permitted hereunder.

         2.      Restrictive Legend.  Each Warrant Certificate and each
certificate representing Shares issued upon exercise of a Warrant, unless such
Shares are then





                                      -1-
<PAGE>   2

registered under the Securities Act of 1933, as amended (the "Act"), shall bear
a legend in substantially the following form:

        "THE [SECURITIES] REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN 
        REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT OF 1933 OR THE 
        SECURITIES OR BLUE SKY LAWS OF ANY STATE AND MAY BE OFFERED AND SOLD 
        ONLY IF REGISTERED AND QUALIFIED PURSUANT TO RELEVANT PROVISIONS OF 
        FEDERAL AND STATE SECURITIES OR BLUE SKY LAWS OR IF AN EXEMPTION FROM
        SUCH REGISTRATION OR QUALIFICATION IS APPLICABLE."
                                                                        
         3.      Exercise. Subject to the terms hereof, the Warrants evidenced
by this Warrant Certificate may be exercised at the Exercise Price in whole or
in part at any time during the period (the "Exercise Period") commencing on
June 18, 1997 and terminating at 5:00 p.m., Central standard time, on April 30,
2002 (the "Expiration Date"). The Exercise Period may be extended by the
Company's Board of Directors.

                 A Warrant shall be deemed to have been exercised immediately
prior to the close of business on the date (the "Exercise Date") of the
surrender to the Company at its principal offices of this Warrant Certificate
with the exercise form attached hereto completed and executed by the Registered
Holder and accompanied by payment to the Company, in cash or by check (which
shall be accepted subject to collection), of an amount equal to the aggregate
Exercise Price for the Warrants being exercised, in lawful money of Canada.

                 The person entitled to receive the Shares issuable upon
exercise of a Warrant or Warrants ("Warrant Shares") shall be treated for all
purposes as the holder of such Warrant Shares as of the close of business on
the Exercise Date. The Company shall not be obligated to issue any fractional
share interests in Warrant Shares issuable or deliverable on the exercise of
any Warrant or scrip or cash with respect thereto, and such right to a
fractional share shall be of no value whatsoever. If more than one Warrant
shall be exercised at one time by the same Registered Holder, the number of
full Shares which shall be issuable on exercise thereof shall be computed on
the basis of the aggregate number of full shares issuable on such exercise.

                 Promptly, and in any event within ten business days after the
Exercise Date, the Company shall cause to be issued and delivered to the person
or persons entitled to receive the same, a certificate or certificates for the
number of Warrant Shares deliverable on such exercise.

         The Company may deem and treat the Registered Holder of the Warrants
at any time as the absolute owner thereof for all purposes, and the Company
shall not be affected by any notice to the contrary. The Warrants shall not
entitle the Registered

Holder thereof to any of the rights of shareholders or to any dividend declared
on the Shares unless the Registered Holder shall have exercised the Warrants
and thereby purchased the Warrant Shares prior to the record date for the
determination of holders of Shares entitled to such dividend or other right.

         4.      Reservation of Shares and Payment of Taxes. The Company
covenants that it will at all times reserve and have available from its
authorized Common Stock such number of Shares as shall then be issuable on the
exercise of outstanding Warrants. The Company covenants that all Warrant Shares
which shall be so issuable shall be duly and validly issued, fully paid and
nonassessable, and free from all taxes, liens and charges with respect to the
issue thereof.

                 The Registered Holder shall pay all documentary, stamp or
similar taxes and other government charges that may be imposed with respect to
the issuance, transfer or delivery of any Warrant Shares on exercise of the
Warrants. In the event the Warrant Shares are to be delivered in a name other
than the name of the Registered Holder of the Warrant Certificate, no such
delivery shall be made unless the person requesting the same has paid the
amount of any such taxes or charges incident thereto.

                 5.       Registration of Transfer. The Warrant Certificates
may be transferred in whole or in part, provided any such transfer complies
with all applicable securities laws. Warrant Certificates to be transferred
shall be surrendered to the Company at its principal office. The Company shall
execute, issue and deliver in exchange therefor the Warrant Certificate or
Certificates which the Registered Holder making the transfer shall be entitled
to receive.

                 The Company shall keep transfer books at its principal office
which shall register Warrant Certificates and the transfer thereof. On due
presentment of any Warrant Certificate for registration of transfer at such
office, the Company shall execute, issue and deliver to the transferee or
transferees a new Warrant Certificate or Certificates representing an equal
aggregate number of Warrants. All Warrant Certificates presented
for registration of transfer or exercise shall be duly endorsed or be
accompanied by a written instrument or instruments of transfer in form
satisfactory to the Company. The Company may require payment of a sum
sufficient to cover any tax or other government charge that may be imposed in
connection therewith.

                 All Warrant Certificates so surrendered, or surrendered for
exercise, or for exchange in case of mutilated Warrant Certificates, shall be
promptly canceled by the Company and thereafter retained by the Company until
the Expiration Date. Prior to due presentment for registration of transfer
thereof, the Company may treat the Registered Holder of any Warrant Certificate
as the absolute owner thereof (notwithstanding any notations of ownership or
writing thereon made by anyone other

than the Company), and the Company shall not be affected by any notice to the
contrary.

         6.      Loss or Mutilation. On receipt by the Company of evidence
satisfactory as to the ownership of and the loss, theft, destruction or
mutilation of this Warrant Certificate, the Company shall execute and deliver,
in lieu thereof, a new Warrant Certificate representing an equal aggregate
number of Warrants. In the case of loss, theft or destruction of any Warrant
Certificate, the individual requesting issuance of a new Warrant Certificate
shall be required to indemnify the Company in a form and amount satisfactory to
the Company. In the event a Warrant Certificate is mutilated, such Certificate
shall be surrendered and canceled by the Company prior to delivery of a new
Warrant Certificate. Applicants for a new Warrant Certificate shall also comply
with such other regulations and pay such other reasonable charges as the
Company may prescribe.

         7.      Adjustment of Shares. The number and kind of securities
issuable upon exercise of a Warrant shall be subject to adjustment from time to
time upon the happening of certain events, as follows:

                          (a)     Stock Splits, Stock Combinations and Certain
                 Stock Dividends. If the Company shall at any time subdivide or
                 combine its outstanding Shares, or declare a dividend in
                 Shares or other securities of the Company convertible into or
                 exchangeable for Shares, a Warrant for the same Exercise Price
                 shall, after such subdivision or combination or after the
                 record date for such dividend, be exercisable for that number
                 of Shares and other securities of the Company that the
                 Registered Holder would have owned immediately after such
                 event with respect to the Shares and other securities for
                 which a Warrant may have been exercised immediately before
                 such event had the Warrant been exercised immediately before 
                 such event. Any adjustment under this Section 7(a) shall
                 become effective at the close of business on the date the
                 subdivision, combination or dividend becomes effective.

                          (b)     Adjustment for Reorganization, Consolidation,
                 Merger. In case of any reorganization of the Company (or any
                 other corporation the stock or other securities of which are
                 at the time receivable upon exercise of a Warrant) or in case
                 the Company (or any such other corporation) shall merge into
                 or with or consolidate with another corporation or convey all
                 or substantially all of its assets to another corporation or
                 enter into a business combination of any form as a result of
                 which the Shares or other securities receivable upon exercise
                 of a Warrant are converted into other stock or securities of
                 the same or another corporation, then and in each such case,
                 the Registered Holder of a Warrant, upon exercise of the
                 purchase right at any time after the consummation of such
                 reorganization, consolidation, merger, conveyance or
                 combination, shall for the





                                      -4-
<PAGE>   5


                 same Exercise Price be entitled to receive, in lieu of the
                 Shares or other securities to which such Registered Holder
                 would have been entitled had he exercised the purchase right
                 immediately prior thereto, such stock and securities which
                 such Registered Holder would have owned immediately after such
                 event with respect to the Shares and other securities for
                 which a Warrant may have been exercised immediately before
                 such event had the Warrant been exercised immediately prior to
                 such event.

                 In each case of an adjustment in the Shares or other
securities receivable upon the exercise of a Warrant, the Company shall
promptly notify the Registered Holder of such adjustment. Such notice shall set
forth in reasonable detail the facts upon which such adjustment is based.

         8.      Reduction in Exercise Price at Company's Option. The Company's
Board of Directors may, at its sole discretion, reduce the Exercise Price of
the Warrants in effect at any time either for the remaining life of the
Warrants or any shorter period of time determined by the Company's Board of
Directors. The Company shall promptly notify the Registered Holders of any such
reduction in the Exercise Price.

         9.      Registration Rights.

(a)              If, at any time during the Exercise Period and the three (3)
years following any exercise hereunder, the Company proposes to file a
registration statement with respect to any class of securities (other than
pursuant to a registration statement on Forms S-4 or S-8 or any successor form)
under the Securities Act, the Company shall notify the Registered Holder at
least twenty (20) days prior to the filing of such registration statement and
will offer to include in such registration statement all or any portion of the
Warrant Shares. In a written notice to be delivered to the Company within
twenty (20) days after receipt of any such notice from the Company, the
Registered Holder shall state the number of Warrant Shares that it wishes to
register for resale and distribution publicly under the proposed registration
statement. The Company will use its best efforts, through its officers,
directors, auditors and counsel in all matters necessary or advisable, to file
at least one (1) such registration statement by November 30, 1997. The Company
will also use its best efforts, through its officers, directors, auditors and
counsel in all matters necessary or advisable, to include within the coverage
of each such registration statement (except as hereinafter provided) the
Warrant Shares that Registered Holder has advised the Company that Registered
Holder wishes to register pursuant to such registration statement for resale
and distribution, to prosecute each such registration statement diligently to
effectiveness, to cause such registration statement to become effective as
promptly as practicable, and to register or qualify the securities so being
registered under such state and provincial securities or "blue sky" laws as the
Registered Holder may reasonably request. In that regard, the





                                      -5-
<PAGE>   6

Company makes no representations or warranties as to its ability to have any
registration statement declared effective.

         All registrations requested pursuant to this Section 9(a) are referred
to herein as "Piggyback Registrations." In the event the Company is advised by
the staff of the Securities and Exchange Commission, Nasdaq Stock Market or any
self-regulatory or state securities agency that the inclusion of the Warrant
Shares will prevent, preclude or materially delay the effectiveness of a
registration statement filed, the Company, in good faith, may amend such
registration statement to exclude the Warrant Shares without otherwise
affecting the Registered Holder's rights to any other registration statement
herein.

                          (i)     Primary Registrations. If a Piggyback
         Registration is an underwritten primary registration on behalf of the
         Company, and if the underwriter thereof advises the Company in writing
         that in its opinion the number of Warrant Shares requested to be
         included in such registration statement exceeds the number that can be
         sold in such offering without materially adversely affecting the
         distribution of such securities by the Company, then the Company will
         include in such registration statement first, the securities that the
         Company proposes to sell and second, the securities requested to be
         included in such registration statement by selling security holders,
         such rights to inclusion being apportioned pro rata among the
         Registered Holder and the other holders of any other securities
         requesting registration according to the market value of Warrant
         Shares and other securities requested to be registered.

                          Notwithstanding the above, if any such underwriter
         shall advise the Company in writing that the distribution of the
         Warrant Shares being included in the registration statement
         concurrently with the securities being registered by the Company would
         materially adversely affect the distribution of such securities by the
         Company, then the Registered Holder shall delay its offering and sale
         for such period ending on the earliest of (a) one hundred eighty (180)
         days following the effective date of the Company's registration
         statement, (b) the earliest date that, in the opinion of such
         underwriter, such adverse effect would no longer be caused, or (c)
         such date as the Company, managing underwriter and Registered Holder
         shall otherwise agree. In the event of such delay, the Company shall
         file such supplements and post-effective amendments and take any such
         other actions as may be necessary or appropriate to permit such
         Registered Holder to make its proposed offering and sale for a period
         of at least ninety (90) days commencing immediately following the end
         of such period of delay. If any party





                                      -6-
<PAGE>   7

         disapproves of the terms of any such underwriting, it may elect to
         withdraw therefrom by written notice to the Company, the underwriter
         and the Registered Holder. Notwithstanding the foregoing, the Company
         shall not be required to include Warrant Shares within the coverage of
         a registration statement being filed pursuant to this Section 9(a)(i)
         if, in the opinion of counsel for both the Company and Registered
         Holder, all of the Warrant Shares proposed to be registered may be
         immediately transferred pursuant to the provisions of Rule 144 under
         the Securities Act.

                 (ii)     Priority on Secondary Registrations. If a Piggyback
         Registration is an underwritten secondary registration on behalf of
         holders of securities of the Company, and the underwriter thereof
         advises the Company in writing that in its opinion the number of
         Warrant Shares requested to be included in such registration statement
         exceeds the number which can be sold in such offering without
         materially adversely affecting the distribution of such securities,
         then the Company will include in such registration statement the
         securities requested to be included in such registration statement by
         selling securityholders on a pro rata basis, with such rights to 
         inclusion being apportioned among the Registered Holder and the other
         holders of any other securities requesting registration according to
         the market value of Warrant Shares and other securities requested by
         them, respectively, to be registered. Notwithstanding the foregoing,
         the Company shall not be required to include Warrant Shares within the
         coverage of a registration statement being filed pursuant to this
         Section 9(a)(ii) if, in the opinion of counsel for both the Company
         and Registered Holder, all of the Warrant Shares proposed to be
         registered may be immediately transferred pursuant to the provisions
         of Rule 144 under the Securities Act.

                 (b)      If at any time after June 18, 1997 and prior to the
third (3rd) anniversary of the earlier of the Expiration Date and the exercise
of the final Warrant represented hereby and the Warrant Shares issued or
issuable upon exercise of the Warrants represented hereby are not then
registered under one or more Piggyback Registrations and then covered by a
prospectus complying with the requirements of the Securities Act, the
Registered Holder may by written notice to the Company require the Company to
file a registration statement under the Securities Act covering such Warrant
Shares as the Registered Holder may specify in such notice. A Registered Holder
shall be entitled so to require the Company to file a registration statement
pursuant to this Section 9(b) on only one (1) occasion. The Company will file
such a registration statement within ninety (90) days of receipt of such
notice; and thereafter will prosecute such registration statement diligently to
effectiveness; will cause such registration statement to become effective as
promptly as practicable; will promptly file all such





                                      -7-
<PAGE>   8

supplements and post-effective amendments to such registration statement and
take any such other actions as may be necessary or appropriate to make
available to Registered Holder on as continuous a basis as is practicable a
prospectus meeting the requirements of the Securities Act through the earliest
of (a) the date on which the final Warrant Shares have been sold and
distributed by Registered Holder, (b) the date on which, in the opinion of
counsel for both the Company and Registered Holder, all of the Warrant Shares
which Registered Holder then holds may be immediately transferred pursuant to
the provisions of Rule 144 under the Securities Act, and (c) April 30, 2002;
and will register or qualify the securities so being registered under such
state and provincial securities or "blue sky" laws as the Registered Holder may
reasonably request. In that regard, the Company makes no representations or
warranties as to its ability to have any registration statement or
post-effective amendment thereto declared effective.

                 (c)      In the event of any registration of a security
pursuant to this Section 9, the Company shall indemnify the Registered Holder
and its officers, directors and other controlling persons against all losses,
claims, damages and liabilities caused by any untrue statement or alleged
untrue statement of a material fact contained in any registration statement or
prospectus (and as amended or supplemented) relating to such registration, or
caused by any omission or alleged omission to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in
light of the circumstances under which they are made unless such statement or
omission was made in reliance upon and in conformity with information furnished
to the Company by the Registered Holder expressly for use therein. The
Registered Holder shall also indemnify the Company, its officers and directors
and each underwriter of the Warrant Shares so registered with respect to
losses, claims damages and liabilities caused by any untrue statement or
omission made in reliance upon and in conformity with information furnished by
the Registered Holder to the Company in writing expressly for use in such
registration statement or prospectus.

                 (d)      All expenses of any registration referred to in this
Section 9, except the fees and disbursements of counsel to the Registered
Holder, underwriting commissions or discounts and any transfer or other taxes
applicable to the transfer of Warrant Shares by the Registered Holder, shall
be borne by the Company.

                 (e)      Following the exercise of Warrants hereunder and the
disposition of Warrant Shares, the Registered Holder shall promptly advise the
Company when Registered Holder no longer holds any Warrant Shares acquired
through the exercise of Warrants hereunder, and upon the request of the
Company, the Registered Holder shall advise the Company from time to time of
the number of Warrant Shares then held by Registered Holder.

                 (f)      The registration rights granted hereunder to the
Registered Holder with respect to Warrant Shares shall also apply to any other
shares of the Company's





                                      -8-
<PAGE>   9

Common Stock or other securities issued by the Company other than Warrants
which are then held by the Registered Holder and constitute "restricted
securities" as that term is defined in Rule 144 promulgated under the
Securities Act, on the same basis as if such securities were Warrant Shares.

         10.     Notices. All notices, demands, elections, or requests
                 (however characterized or described) required or authorized
                 hereunder shall be deemed given sufficiently if in writing and
                 sent by registered or certified mail, return receipt requested
                 and postage prepaid, or by facsimile or telegram to the
                 Company, at its principal executive office, and to the
                 Registered Holder, at the address of such holder as set forth
                 on the books maintained by the Company.

         11.     General Provisions. This Warrant Certificate shall be
construed and enforced in accordance with, and governed by, the laws of the
Province of Ontario. Except as otherwise expressly stated herein, time is of
the essence in performing hereunder. The headings of this Warrant Certificate
are for convenience in reference only and shall not limit or otherwise affect
the meaning hereof.

         IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to
be duly executed as of the 24th day of June, 1997.
