     Certain statements in this Report under the captions "Item 1. Business and
Item 2. Properties" and Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operations", and elsewhere in this Report
constitute "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995 (the "Reform Act").  Such forward-
looking statements involve known and unknown risks, uncertainties and other
factors which may cause the actual result, performance or achievements of the
Company, or industry trends and results, to be materially different from any
future results, trends, performance, or achievements expressed or implied by
such forward-looking statements.  Such risks, uncertainties and other factors
include, among others, the following:  general economic and business conditions;
oil and gas and other industry conditions and trends, including supply and
demand; fluctuations in the prices for oil, gas and refined products;
competition; import protection and regulation (including the implementation of
the World Trade Organization and North American Free Trade Agreement; the loss
of any significant customers; changes in business strategy or development plans;
quality of management; availability, terms and deployment of debt and equity
capital; business abilities and judgment of personnel; availability of qualified
personnel; changes in or the failure to comply with government regulations; and
other factors referenced in this Report.  See "Item 1. Business and Item 2.
Properties - Cautionary Statement and Risk Factors."

     Without limiting the foregoing, as disclosed in "Item 1. Business and
Item 2. Properties--Proposed Merger with Alliance Resources Plc," the Company
has entered into an Agreement and Plan of Merger with Alliance Resources PLC
("Alliance") pursuant to which the Company will merge (the "Merger") with a
wholly-owned subsidiary of Alliance.  Pursuant to the Merger, two of the current
directors of the Company will become directors of Alliance, but the management
of the combined companies will otherwise consist of the current management of
Alliance.  Statements made in this Report concerning future drilling,
acquisitions, budgets, spending, capital needs, operating plans and other
activities are made on behalf of the current management of the Company and will
not be indicative of the plans of the new management or activities of the
combined companies in the event the Merger is completed.

Item 1.   Business and Item 2. Properties.

          As used in this Form 10-K:

          "Mcf" means thousand cubic feet, "MMcf" means million cubic feet and
"Bcf" means billion cubic feet.  "Mcfe" means thousand cubic feet equivalent,
"MMcfe" means million cubic feet equivalent and "Bcfe" means billion cubic feet
equivalent.  "Bbl" means barrel, "MBbls" means thousand barrels and "MMBbls"
means million barrels. "BOE" means equivalent barrels of oil and "MBOE" means
thousands equivalent barrels of oil.  Unless otherwise indicated herein, natural
gas volumes are stated at the legal pressure base of the state or area in which
the reserves are located and at 60 (degrees) Fahrenheit. Natural gas equivalents
are determined using the ratio of six Mcf of natural gas to one Bbl of crude
oil.

          The term "gross" refers to the total leasehold acres or wells in which
the Company has a working interest. The term "net" refers to gross leasehold
acres or wells multiplied by the percentage working interest owned by the
Company.  "Net production" means production that is owned by the Company less
royalties and production due others.

          "Proved reserves" are estimated quantities of crude oil, natural gas
and natural gas liquids, 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 reserves"
are those reserves which are expected to be recovered through existing wells
with existing equipment and operating methods.  "Proved undeveloped reserves"
are those reserves which are expected to be recovered from new wells on
undrilled acreage or from existing wells where a relatively major expenditure is
required for recompletion.

          The term "oil" includes crude oil, condensate and natural gas liquids.

          Unless the context requires otherwise, all references to the "Company"
include LaTex Resources, Inc., and its consolidated subsidiaries including,
LaTex Petroleum Corporation ("LaTex Petroleum"), LaTex/GOC Acquisition, Inc.
("GOCA"), Germany Oil Company, formerly known as LRI Acquisition, Inc.
("Germany"), ENPRO, Inc. ("ENPRO"), Phoenix Metals, Inc. ("Phoenix Metals"), and
LaTex Resources International, Inc. ("LaTex Resources International").

The Company

          LaTex Resources, Inc. ("the Company") is an independent oil and gas
company primarily engaged in the acquisition of producing oil and gas properties
which possess the potential for increased value through exploitation and
development.  The Company seeks to realize such potential through workovers,
recompletions, secondary recovery operations, and the drilling of development or
infill wells.  The Company is also engaged in the purchase and marketing of
crude oil and natural gas and the exploration and development of non-producing
oil and gas properties.

          The Company owns and operates producing oil and gas properties located
in 12 states, with proved reserves located primarily in the states of
Mississippi, Louisiana, Oklahoma, Texas, and Alabama.  Since July 31, 1991, the
Company has acquired approximately 4,500 MBbls of crude oil and 25.8 Bcf of
natural gas reserves involving total capital expenditures of approximately
$30,840,000 for an average acquisition cost of $3.50 per BOE.  Daily gross
production from 156 wells operated by the Company in these states currently
averages approximately 1,055 Bbls of oil and 7,600 Mcf of gas. The Company also
owns interests in 342 producing wells and units in the same states which are
operated by others.  Daily gross production from both operated and non-operated
wells, net to the Company's interest, currently averages approximately 1,000
Bbls of oil and 8,000 Mcf of gas from a total of 95 net wells.

          From the end of its first year of oil and gas operations in 1987, the
Company's proved reserves have grown from 10 MBOE to 11,048 MBOE at July 31,
1996.  At July 31, 1996, the Company's proved reserves were 6,353 MBbls of oil
and 28.2 Bcf of gas.  The Company has increased its average net daily

                                       3
<PAGE>
 
production from two Bbls of oil during 1987 to 1,000 Bbls of oil and 8,000 Mcf
of gas at July 31, 1996.  See "Item 1. Business and Item 2. Properties -
Reserves."

          The Company has agreed to sell approximately 400 non-strategic oil and
gas properties for  total consideration of approximately $1,526,000, before
adjustments.  The oil and gas reserve analysis, well count, acreage summaries
and other data included in this Item I. Business and Item 2. Properties for the
year ended July 31, 1996 do not include these properties.

Historical Background

          The Company's predecessor was incorporated as a Texas corporation in
1981 under the name Video Science Technology, Inc. ("VSTI") and was initially
organized to research, develop and market specialized video systems and products
pertaining to medical, petroleum and low power television applications.  By
1988, substantially all of VSTI's original businesses had been terminated and
VSTI had become substantially inactive.

          In December 1991, Jeffrey T. Wilson ("Wilson"), James G. Borem
("Borem") and Dewitt C. Shreve ("Shreve"), agreed to exchange (the "LaTex
Exchange Transaction") all outstanding shares of common stock of LaTex Petroleum
Corporation, an Oklahoma corporation ("LaTex Petroleum"), for a total of
7,000,000 newly issued shares of VSTI's common stock representing approximately
61% of VSTI's resulting issued and outstanding common stock.  As a result, LaTex
Petroleum became a wholly owned subsidiary of VSTI.  VSTI moved its principal
offices from Dallas, Texas to its current offices located in Tulsa, Oklahoma and
Messrs. Borem, Wilson and Shreve were elected the Directors and executive
officers of VSTI.  As a result of the LaTex Exchange Transaction, VSTI resumed
operation through its wholly-owned subsidiary, LaTex Petroleum, in the business
of acquisition of producing oil and gas properties and exploration for and
production of oil and gas.

          In May 1992, VSTI was merged (the "Reincorporation Merger") with and
into the Company (which had been formed as a wholly-owned subsidiary of VSTI
solely for the purpose of effecting the Reincorporation Merger).  As a result of
the Reincorporation Merger, the state of incorporation of the Company was
changed from Texas to Delaware and the name of the Company was changed from
"Video Science Technology, Inc." to "LaTex Resources, Inc.".   Each outstanding
share of stock of VSTI was converted into one share of stock of the Company and
the existing shareholders of VSTI automatically became shareholders of the
Company.  The Reincorporation Merger did not result in any change in the
physical location, business, management, or financial condition of the Company.

          In November 1992 the Company completed a public offering of 1,125,000
units, each unit consisting of one share of common stock and two redeemable
Stock Purchase Warrants to purchase one share of common stock.  The purchase
price for the units under the offering was $3.70 per unit.  Net proceeds to the
Company from the offering, approximately $4,226,063, were used to pay off the
Company's then existing bank debt and for working capital.

Proposed Merger With Alliance Resources Plc

          The Company has entered into an Agreement and Plan of Merger
("Alliance Merger Agreement") dated August 12, 1996 with Alliance Resources Plc,
a company organized under the laws of the United Kingdom ("Alliance"), pursuant
to which the Company will merge ("Alliance Merger") with a wholly-owned U.S.
subsidiary of Alliance.

          Under the terms of the Alliance Merger Agreement and after giving
effect to a 1 for 40 reverse stock split to be completed by Alliance, the
holders of the Company's common stock will receive 0.8806 ordinary shares of
Alliance for each share of such common stock, the holders of the Company's
Series A Convertible Preferred Stock will receive 2.6445 ordinary shares of
Alliance for each share of such Series A Convertible Preferred Stock, and the
holders of the Company's Series B Senior Convertible Preferred Stock will
receive 5.8709 ordinary shares of Alliance for each share of such Series B
Senior Convertible Preferred Stock.  Following the Alliance Merger, the holders
of the Company's common and preferred stock will own, as a group, approximately
72% of the issued and outstanding ordinary shares of Alliance and the Company
will become a wholly-owned subsidiary of Alliance.  Holders of outstanding
warrants

                                       4
<PAGE>
 
to purchase shares of the Company's common stock will receive from Alliance
replacement warrants to purchase shares of Alliance ordinary shares on
substantially the same terms.

          Under the terms of the Alliance Merger Agreement, the Company is
required to dispose of its interests in its unconsolidated affiliates Wexford
Technology, Inc. ("Wexford") and Imperial Petroleum, Inc. ("Imperial"), and its
interests in its wholly-owned subsidiaries LaTex Resources International, Inc.
("LaTex Resources International") and Phoenix Metals, Inc. ("Phoenix Metals").
Effective July 31, 1996, the Company has written off its $2,372,452 investment
in Wexford, its $1,797,378 investment in Imperial, and its $3,446,795 investment
in LaTex Resources International (which includes $2,491,299 in dry hole costs
and $955,496 in abandonments relating to the Company's investments in Tunisia
and Kazakhstan, respectively).  Effective July 31, 1994, the Company wrote off
its $222,918 investment in Phoenix Metals.   The Company has entered into a
Purchase Agreement with Imperial pursuant to which the Company will sell its
interests in Wexford, Imperial, LaTex Resources International and Phoenix Metals
to Imperial for 100,000 shares of the Company's common stock.  See "Exploration
and Development", "Other Business" and "Item 7. Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Proposed Merger
With Alliance Resources Plc."

          Pursuant to the Alliance Merger, two of the current directors of the
Company will become directors of Alliance, but the management of the combined
companies will otherwise consist of the current management of Alliance.
Statements made in this Report concerning future drilling, acquisitions,
budgets, spending, capital needs, operating plans and other activities are made
on behalf of the current management of the Company and will not be indicative of
the plans of the new management or activities of the combined companies in the
event the Merger is completed.

Cautionary Statement and Risk Factors

          Cautionary Statement Regarding Forward-Looking Statements.  In the
          ---------------------------------------------------------         
interest of providing the Company's shareholders and potential investors with
certain information regarding the Company, including management's assessment of
the Company's future plans and operations, certain statements set forth in this
Report contain or are based on the Company's projections or estimates of
revenue, income, earnings per share and other financial items or relate to
management's future plans and objectives or to the Company's future economic and
financial performance.  Such statements are "forward-looking statements" within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended, and are made
pursuant to and in reliance on the safe harbor provisions of such sections.

          Although any forward-looking statements contained in this report or
otherwise expressed by or on behalf of the Company are, to the knowledge and in
the judgment of the officers and directors of the Company, expected to prove
true and to come to pass, management is not able to predict the future with
absolute certainty.  Forward-looking statements involve known and unknown risks
and uncertainties which may cause the Company's actual performance and financial
results in future periods to differ materially from any projection, estimate or
forecasted result.  These risks and uncertainties include, among other things:
volatility of oil and gas prices; product supply and demand; market competition;
risks inherent in the Company's oil and gas operations both domestic and
foreign; imprecision of reserve estimates; the Company's ability to replace and
expand oil and gas reserves; the Company's ability to generate sufficient cash
flow from operations to meet its current and future obligations; the Company's
ability to access external sources of debt and equity capital; and such other
risks and uncertainties described from time to time in the Company's periodic
reports and filings with the Securities and Exchange Commission.  These and
other risks are described elsewhere in this report and in the Company's other
filings with the Securities and Exchange Commission.  Accordingly, shareholders
and potential investors are cautioned that certain events or circumstances could
cause actual results to differ materially from those projected, estimated or
predicted.  In addition, forward-looking statements are based on management's
knowledge and judgment as of the date of this report, and the Company does not
intend to update any forward-looking statements to reflect events occurring or
circumstances existing hereafter.

            History of Losses; Accumulated Deficit.  For the fiscal years ended
            --------------------------------------                             
July 31, 1996, 1995 and 1994, the Company incurred net losses of $10,230,783,
$2,491,342 and $423,341 respectively.  At July 31, 1996, the Company had an
accumulated deficit of $11,747,860 and its working capital deficit was
$28,420,291.

                                       5
<PAGE>
 
It is expected that the Company will continue to experience losses and that, in
order to achieve profitability and generate cash flow, it will be dependent upon
acquiring additional debt or equity capital and acquiring or developing
additional oil and gas properties.  There can be no assurance that the Company
will be able to do so.  See "Item 7.  Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Item 8.  Financial
Statements and Supplementary Data."

          Limited Available Capital; Need for Additional Financing.  Without
          --------------------------------------------------------          
raising additional capital, the Company will be unable to acquire additional
producing oil and gas properties and its ability to develop its existing oil and
gas properties will be limited to the extent of available cash flow.
Accordingly, in order for the Company to achieve its business objective and
achieve profitable operations, it will be necessary to generate additional cash
flow from operations, raise additional capital or enter into joint oil and gas
development arrangements.  Management intends to fund future acquisitions and
develop its oil and gas reserves using cash flow from operations as well as
borrowings, public and private sales of debt and equity securities and joint oil
and gas development arrangements, among other possible sources.  The Company
estimates that it will need approximately $800,000 of capital to develop its
undeveloped oil and gas reserves during the year ended July 31, 1997 and an
additional $1,000,000 to develop such reserves during the following year.  The
Company expects to obtain these funds from cash flow, the proceeds from the sale
of certain non-strategic oil and gas properties, and additional borrowings.  The
Company has no present arrangements for future borrowings and its cash flow from
operations is not expected to be adequate to provide the funds needed for these
purposes.  Although the Company has agreed to sell certain non-strategic oil and
gas properties for approximately $1.5 million, before adjustments, there can be
no assurance that this transaction or other sources will provide funds in
sufficient amounts to allow the Company to successfully implement its present
business strategy of additional oil and gas property acquisitions or the
development of its existing oil and gas reserves.  The Company has no present
arrangements to raise additional capital from the sale of its securities or
joint development arrangements.  No assurance can be given as to the
availability or terms of any such additional financing or joint development
arrangements or that such terms as are available may not be dilutive to the
interests of the Company's shareholders.  See "Item 7.  Management's Discussion
and Analysis of Financial Condition and Results of Operations" and "Item 8.
Financial Statements and Supplementary Data."

          Credit Facility Covenants and Restrictions.  The Company currently
          ------------------------------------------                        
owes approximately $22,206,707 under its credit facility with the Company's
principal bank.  The interest rate on the indebtedness is, at the option of the
Company, either the lending bank's base interest rate plus 1% or up to 2% (based
on the principal balance outstanding) over the rate for borrowing dollars by the
lending bank in the London Interbank market.  The principal must be amortized at
the rate of $365,000 per month with the entire outstanding balance due March 31,
2000.  The credit facility is secured by first mortgages on all of the Company's
oil and gas properties.  The loan agreement relating to the credit facility
contains various affirmative and negative covenants including, among others, the
requirements that the Company maintain certain ratios of current assets to
current liabilities, minimum tangible net worth, restrictions on selling,
general and administrative expenses and the payment of dividends.  Material
breaches of these or other covenants which are not cured or waived could result
in a default under the loan agreement resulting in this indebtedness becoming
immediately due and payable and empowering the lender to foreclose against the
collateral for the loan.  The Company has been in default under various
affirmative and negative covenants of the loan agreement with its principal bank
with respect which the bank agreed to not take any action before November 29,
1996.  The Bank has indicated its willingness to extend its agreement to forbear
any action on the Company's default through February 28, 1997.  If the Company
cannot cure its default, the bank could declare the balance due and foreclose on
the Company's oil and gas properties.  Under such circumstances the Company's
shareholders could lose their entire investment.  See "Item 7.  Management's
Discussion and Analysis of Financial Condition and Results of Operations -
Capital Resources and Liquidity".

          Industry Conditions; Impact on Company's Profitability.  The
          ------------------------------------------------------      
profitability and revenues of the Company are dependent, to a significant
extent, upon prevailing market prices for oil and gas.  In the past, oil and gas
prices and markets have been volatile.  Prices are subject to wide fluctuations
in response to changes in supply of and demand for oil and gas, market
uncertainty and a variety of additional factors that are beyond the control of
the Company.  Such factors include supply and demand, political conditions,
weather conditions, government regulations, the price and availability of
alternative fuels and

                                       6
<PAGE>
 
overall economic conditions.  Crude oil and natural gas prices have increased
significantly over the past 12 months.  Any decline from current oil or gas
prices would have a material adverse effect on the Company's revenues and
operating income and might, under certain conditions, require a write-down of
the book value of the Company's oil and gas properties.  If such declines were
severe enough, they could result in a reduction in the Company's borrowing base
under its credit facility with its principal bank and could require the sale of
some of its properties under unfavorable market conditions or require the
Company to seek additional debt or equity capital.  There can be no assurance
that the Company could, if the need arose, effect any sale of its debt or equity
securities on terms acceptable to the Company or on terms which would not be
dilutive to the Company's shareholders.  See "Marketing".

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

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

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

          Reliance on Key Personnel.  The Company is dependent upon the services
          -------------------------                                             
of its President, Jeffrey T. Wilson, its Vice President and Chief Financial
Officer, John L. Cox, its Vice President of Operations, Robert L. Hull, and its
Vice President of Exploration, John W. Heinsius.  The loss of their services
could have a material adverse effect upon the Company.  The Company does not
have employment agreements with Messrs. Wilson, Cox, Hull or Heinsius.  The
Company does not maintain insurance on the lives of

                                       7

Messrs. Wilson, Cox, Hull or Heinsius.  See "Item 10.  Directors and Executive
Officers of the Registrant."

          Competition.  The oil and gas industry is highly competitive.  The

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

          Operational Hazards, Environmental Concerns, Insurance and Government
          ---------------------------------------------------------------------
Regulation.  The oil and gas industry involves a number of operating risks, such
- ----------                                                                      
as the risks of fire, blowouts, explosions, cratering, pipe failure, casing
collapse and abnormally pressured formations, the occurrence of any of which
could materially and adversely affect the Company.  The business is also subject
to environmental hazards including oil and saltwater spills, gas leaks, ruptures
and discharges of toxic gases.  These risks could result in substantial losses
to the Company due to injury and loss of life, severe damage to and destruction
of property and equipment, pollution and other environmental damage, and
suspension of operations.  As the owner of working interests in its oil and gas
properties, the Company bears its proportionate share of the obligations and
liabilities arising out of the exploration and development of those properties.
Generally, owners of working interests in oil and gas properties are jointly and
severally liable for all such obligations and liabilities.  As a result, there
exists a risk that the Company could become liable for amounts in excess of its
proportionate share of such obligations and liabilities, although generally the
Company would have a right of contribution against the other working interest
owners.  In accordance with customary industry practices, the Company maintains
insurance against some, but not all, of such risks and some, but not all of such
losses.  The occurrence of such an event not fully covered by insurance could
have a material adverse effect on the financial position and operations of the
Company.  The Company maintains insurance against some, but not all, potential
risks, and does not carry insurance covering environmental impairment
liabilities.  The Company can provide no assurance that the insurance it carries
will be adequate to cover any loss or exposure to liability, or that such
insurance will continue to be available on terms acceptable to the Company.  See
"Operational Hazards and Insurance".

          Effect of Warrants and Convertible Preferred Stock Outstanding.  The
          --------------------------------------------------------------      
Company has outstanding (i) warrants which provide for the purchase of an
aggregate of 3,034,750 shares of common stock at prices ranging from $0.75 to
$4.44 per share, (ii) shares of Series A Convertible Preferred Stock ("Series A
Preferred Stock") convertible into an aggregate of 1,350,835 shares of common
stock, if calculated as of July 31, 1996, and (iii) shares of Series B Senior
Convertible Preferred Stock ("Series B Preferred Stock") convertible into an
aggregate of 3,200,167 shares of common stock, if calculated as of July 31,
1996.  Issuances of shares of the Company's common stock upon exercise of
warrants or conversion of shares of preferred stock will have a dilutive effect
on the Company's shareholders by decreasing their percentage ownership in the
Company.

          Registration Rights.  The holders of the outstanding shares of the
          -------------------                                               
Company's Series A Preferred Stock and Senior B Preferred Stock and the holders
of warrants to purchase up to 305,000 shares of the Company's common stock have
the right to either require the Company to register shares of the Company's
common stock issuable upon conversion of such preferred stock or exercise of
such warrants under the Securities Act of 1933 ("Securities Act") or to have
such shares included in any registration statement filed by the Company, subject
to certain limitations, to enable a public sale of those shares.  In the event
the holders of a material amount of such shares should seek to have their shares
registered for sale under the Securities Act, these obligations could result in
considerable expense to the Company and the effect of the offer and sale of such
shares may be to depress the market price for the Company's common stock.
Compliance with these obligations may also interfere with the Company's ability
to raise additional capital when required.

          Authorization and Discretionary Issuance of Preferred Stock; Anti-
          -----------------------------------------------------------------
takeover Provisions.  The Company's Certificate of Incorporation authorizes the
- -------------------                                                            
issuance of preferred stock with such designations, rights and preferences as
may be determined from time to time by the Board of Directors.  Accordingly, the
Board of Directors is empowered, without shareholder approval, to issue
preferred stock with dividend, liquidation, conversion, voting or other rights
which could adversely affect the voting power or other rights of holders of the
Company's common stock.  In the event of issuance, the preferred stock could be
utilized, under certain circumstances, as a method of discouraging, delaying or
preventing a change in control of the Company, which could have the effect of
discouraging bids for the Company and

                                       8
<PAGE>
 
thereby prevent shareholders from receiving a premium for their shares over the
then-current market prices.  Although the Company has no present intention to
issue any additional shares of its preferred stock (other than in payment of
dividends on the Series A and Series B Preferred Stock), there can be no
assurance that the Company will not do so in the future.

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

          Qualification Requirements for Nasdaq Securities.  The common stock of
          ------------------------------------------------                      
the Company is presently quoted on Nasdaq, which is administered by the National
Association of Securities Dealers, Inc. (the "NASD").  Until September 4, 1996,
the common stock of the Company was also listed on the Pacific Stock Exchange.
Effective September 4, 1996, the common stock was delisted by the Pacific Stock
Exchange as a result of the failure of the minimum share bid price for the
common stock to meet the minimum listing maintenance requirements of the
Exchange.  For the Company's securities to continue to be eligible for inclusion
on Nasdaq, the Company must, among other things, maintain at least $2,000,000 in
total assets and have at least $1,000,000 of capital and surplus and the bid
price of the common stock must be at least $1.00 per share, provided, however,
that, if the Company's stock falls below such minimum bid price, it will remain
eligible for continued inclusion if the market value of the public float is at
least $1,000,000 and the Company has at least $2,000,000 in capital and surplus.
While the Company presently meets the NASDAQ required standards, there can be no
assurance that it will continue to be able to do so.  If this should occur,
trading, if any, in the common stock would then continue to be conducted in the
over-the-counter market on the OTC Bulletin Board, an NASD-sponsored inter-
dealer quotation system, or in what are commonly referred to as "pink sheets."
As a result, a shareholder may find it more difficult to dispose of, or to
obtain accurate quotations as to the market value of, the Company's securities.
In addition, if the Company's securities cease to be quoted on Nasdaq and the
Company fails to meet certain other criteria, those securities would be subject
to a Commission rule that imposes additional sales practice requirements on
broker-dealers who sell such securities to persons other than established
customers and accredited investors.  For transactions covered by this rule, the
broker-dealer must make a special suitability determination for the purchaser
and have received the purchaser's written consent to the transaction prior to
sale.  Consequently, if the Company's securities were no longer quoted on
Nasdaq, the rule may affect the ability of broker-dealers to sell the Company's
securities and the ability of shareholders to sell their securities in the
secondary market.  See "Item 5.  Market for Registrant's Common Equity and
Related Shareholder Matters."

          Dividends Unlikely.  The Company has never declared or paid dividends
          ------------------                                                   
on its common stock and currently does not intend to pay dividends in the
foreseeable future.  The payment of dividends in the future will be at the
discretion of the Board of Directors.  In addition, the Company's credit
facility contains a provision which prohibits the payment of dividends except
for dividends on its shares of Series A and Series B Preferred Stock payable in
the form of additional shares of Series A and Series B Preferred Stock.

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

                                       9

produce and market oil and natural gas.  See "Regulation" and "Recent and
Proposed Legislation."

Business Strategy

          The Company's business strategy has been and will continue to be to
increase shareholder value through the acquisition of producing oil and gas
properties and exploitation of those properties to maximize production and
ultimate reserve recovery.  The Company's growth strategy focuses on the
technical expertise of its management and employees to evaluate acquisitions and
to exploit the development potential of each oil and gas property through
recompletions, workovers, cost reduction measures or marketing efforts.

Acquisition Activities

          Historically, the Company has allocated a substantial portion of its
capital expenditures to the acquisition of producing oil and gas properties.
From July 31, 1991 through July 31, 1996, the Company completed 12 acquisitions
of oil and gas properties, involving total acquisition costs of approximately
$30,840,000 and resulting in an average reserve replacement cost of
approximately $3.50 per BOE.  During the year ended July 31, 1996, the Company
completed the acquisition of approximately  15 oil and gas properties from
Sackett Oil Company for a purchase price of approximately $2,900,000.  A portion
of these properties were subsequently sold by the Company for approximately
$2,800,000.

          To the extent that it has the capital resources to do so, the Company
intends to continue to pursue a business strategy that emphasizes reserve
additions through acquisitions.  The Company may utilize any one or a
combination of lines of credit with banks, public and private sales of debt and
equity securities, joint oil and gas development arrangements and internally-
generated cash flow to finance its acquisition efforts.  No assurance can be
given that sufficient external or internal funds will be available to fund the
Company's desired acquisitions.  See Item 7, "Management's Discussion and
Analysis of Financial Condition and Results of Operations."  The Company may
also use, where appropriate, its equity securities as all or part of the
consideration for such acquisitions.

          Prospective acquisitions are evaluated by the Company's management.
After the acquisition of oil and gas properties, management generally develops a
reservoir depletion plan to maximize production rates, ultimate reserve recovery
and cash flow generation.  Such plans consider field operating procedures,
workovers, recompletions, secondary recovery implementation, additional drilling
and such other procedures as the situation dictates.

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

Exploitation Activities

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

          The expenditures required for the Company's workover and recompletion
program have historically been financed, and it is expected that they will
continue to be financed, by borrowings and internally generated funds.

Production

          The Company owns and operates producing properties located in 12
states, with its proved reserves located primarily in the states of Mississippi,
Louisiana, Oklahoma, Texas, and Alabama.  The Company continuously evaluates the
profitability of its oil, gas and related activities and has a policy of
divesting itself of unprofitable oil and gas properties or areas of operation
that are not consistent with its operating philosophy.

          The Company operates 156 producing wells in these areas and also owns
non-operated interests in 342 producing wells and units. Oil and gas sales from
the Company's producing oil and gas properties accounted for substantially all
of the Company's revenues for the years ended July 31, 1994, 1995, 1996,
respectively.

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

          South Carlton Field, Alabama.  The South Carlton Field is located in
          ----------------------------                                        
Clarke and Baldwin Counties in southwest Alabama.  The Company operates 56
active producing oil wells and three water injection wells.  Production is from
the Massive and Pilot sands of the Tuscaloosa Formation with daily gross
production being approximately 380 Bbls of oil.  Based on the production history
of certain infill wells previously drilled in this field and an extensive
geological and engineering review, the Company believes that additional infill
drilling potential exists for the Tuscaloosa reservoirs.  Net proven reserves to
the Company as of July 31, 1996 are 4,217.3 MBbls of oil.

          Black Warrior Basin, Mississippi and Alabama.  The Company owns
          --------------------------------------------                   
operated and non-operated working interests in 145 wells (55 operated and 90
non-operated) in Lamar, Fayette and Pickens Counties, Alabama and Lee and
Chickasaw Counties, Mississippi.  Production from these wells are from multiple
sandstones of Mississippian age and range in depth from approximately 1,900 feet
to 4,600 feet.  Net proven reserves to the Company as of July 31, 1996, are 30.8
MBbls of oil and 10,733.2 MMcf of gas.

          War-Wink South/East Quito Fields, Texas.  The Company owns non-
          ---------------------------------------                       
operated working interests in 45 active wells operated by Texaco, Chevron, Enron
and BC Operating in the War-Wink South and East Quito Fields in Ward County,
Texas.  These fields produce from the Fusselman, Atoka, Wolfcamp and Cherry
Canyon Formations at depths ranging from 6,200 feet to 17,500 feet.  Based upon
review of geological and engineering data, the Company believes that additional
behind pipe and infill drilling potential exists on these properties.  Net
proven reserves to the Company as of July 31, 1996 are 100.2 MBbls of oil and
2,165.2 MMcf of gas.

          Wolf Mountain Field, Colorado.  The Company operates one well in the
          -----------------------------                                       
Wolf Mountain Field in Routt County, Colorado.  The well produces oil at a daily
rate of 28 Bbls from the Niobrara reservoir at a depth of approximately 5,500
feet.  Additional potential exists behind the pipe to recomplete the well to
other undrained sections of the reservoir.  Net proven reserves to the Company
as of July 31, 1996 are 662.4 MBbls of oil.

          Perkins Field, Louisiana.  The Company operates seven active wells in
          ------------------------                                             
the Perkins Field which produce crude oil on gas lift from various Miocene sands
at depths ranging from approximately 6,000 to 7,500 feet.  The Perkins field is
a multiple reservoir structural feature which is nearing the later stages of
depletion.  Net proven reserves to the Company as of July 31, 1996 are 236.3
MBbls of oil.

          Tinsley Field, Mississippi.  The Tinsley Field is located in Yazoo
          --------------------------                                        
County in north central Mississippi and produces from a series of Selma-Eutaw
sands of Upper Cretaceous age.  The Company operates five active wells and two
water injection wells in the field having a daily gross production of
approximately 85 Bbls of oil.  Through extensive mapping and engineering work,
the Company believes that significant additional oil reserves may remain in
various Eutaw sand and in the underlying Tuscaloosa sand which has not been
extensively tested in the field.  Net proven reserves to the Company as of July
31, 1996 are 282.2 MBbls of oil.

          Bolton Field, Mississippi.  The Bolton Field is located in Hinds
          -------------------------            
County in west central Mississippi.

                                       11
<PAGE>
 
The Company operates two wells in the field and has non-operated interests in
four additional wells.  Production is from the Cotton Valley, Sligo, Rodessa and
Mooringsport Formations.  Daily gross production from the operated wells is 425
Mcf of gas and 20 Bbls of oil.  Based on a review of the field data, the Company
believes that significant behind pipe potential exists in several of the wells.
Net proven reserves to the Company as of July 31, 1996 are 36.6 MBbls of oil and
768.9 MMcf of gas.

          Ozona Field, Texas.  The Ozona Field is located in Crockett County in
          ------------------                                                   
west Texas.  The Company owns non-operated working interests in 24 wells which
produce from the Cisco and Canyon sand reservoirs.  Net proven reserves to the
Company as of July 31, 1996, are 1.0 MBbls of oil and 969 MMcf of gas.

          Turtle Bayou/Deer Island Fields, Louisiana.  These fields are located
          ------------------------------------------                           
in Terrebonne Parish, Louisiana.  Production is from multiple sands,
predominantly in the normal pressured upper and middle Miocene.  The Company
owns non-operated working interests in six producing wells.  Based on geological
and engineering data, the Company believes that additional development potential
exists within the field.  Net proven reserves to the Company as of July 31,
1996, are 7.0 MBbls of oil and 806 MMcf of gas.

          Springhill Field, Arkansas.  The Springhill Field is located in
          --------------------------                                     
Columbia County, Arkansas.  The Company owns royalty interests in five wells
operated by Sonat which produce from the Haynesville formation at a combined
rate of 16.5 MMCf of gas and 335 Bbls of oil per day.  Net proven reserves to
the Company as of July 31, 1996 are 10 MBbls of oil and 667.7 MMcf of gas.

          GOM State Tract 904 Field, Texas.  The GOM State Tract 904 Field is
          --------------------------------                                   
located in offshore waters of Nueces County, Texas.  The Company owns interests
in two wells operated by National Energy Group which produce from the Frio sands
at a combined rate of 80 Bbls of oil and 1150 Mcf of gas per day.  Net proven
reserves to the Company as of July 31, 1996 are 14.6 MBbls of oil and 560.1 MMcf
of gas.

Marketing

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

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

          Changes in oil and natural gas prices significantly affect the
revenues and cash flow of the Company and the value of its oil and gas
properties.  Significant declines in the prices of oil and natural gas could
have a material adverse effect on the business and financial condition of the
Company.  The Company is unable to predict accurately whether the price of oil
and natural gas will rise, stabilize or decline in the future.  In an effort to
protect the Company against fluctuations in oil and gas prices, the Company has
entered into certain commodity hedging arrangements.  See "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations -
Results of Operations."

          Substantially all of the Company's crude oil and condensate production
is sold at posted prices under short term contracts, as is customary in the
industry.  The most significant purchaser of the Company's oil and gas
production (including production sold by the Company's marketing subsidiary,
ENPRO) during the year ended July 31, 1996 was ENRON Reserve Acquisition Corp.
which accounted for 16% of the Company's oil and gas sales.  No other purchaser
of crude oil or natural gas during this period exceeded 10% of the Company's oil
and gas sales.  With respect to losses incurred by the Company as a result of
its crude and natural gas price hedging arrangements, see "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Capital Resources and Liquidity."

          The Company's wholly-owned subsidiary, ENPRO, purchases and resells
crude oil and natural gas in Alabama, Colorado, Louisiana, Mississippi, Montana,
New Mexico, Oklahoma and Texas.  ENPRO currently markets approximately 704 BOE
per day to refiners and large resellers.  For its services, ENPRO receives a
margin which averages approximately 9.75% of gross sales.  ENPRO currently
markets approximately 969 barrels per day of oil from wells operated by the
Company.  By aggregating barrels of crude oil purchased by ENPRO from third
parties with those purchased by ENPRO from the Company, additional revenues are
generated through what the Company believes are improved marketing practices.

          ENPRO owns a crude oil trans-shipment facility in Poyner, Texas
approximately 30 miles south of Tyler, Texas.  The facility consists of 2,410
barrels of storage capacity on four acres owned by ENPRO.   The terminal was
originally constructed and operated as a crude oil blending facility.  The
facility is presently inactive.

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

Exploration and Development

          General.  Development drilling opportunities available to the Company
          -------                                                              
are largely a result of the Company's acquisition of producing oil and gas
properties. Several infill and development locations exist on Company properties
currently producing oil and gas.  As a result, the Company will continue to
evaluate additional opportunities for developmental drilling on its existing
properties.

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

          Outside the United States, the Company has from time to time pursued
foreign exploration concessions which offer limited capital expenditure exposure
through the drilling commitment phase.  However, the Company's focus in the
future will be on domestic oil and gas opportunities.

          Tunisian Prospect.  On June 30, 1993, the Company's wholly-owned
          -----------------                                               
subsidiary, LaTex Resources International, together with Enterprise Tunisienne
D'Activities Petroleries, the Tunisian State Oil Company ("ETAP"), ARCO Tunisia,
Inc. ("ARCO") and Premier Pict Petroleum Ltd. (formerly Pict Petroleum (Tunisia)
Ltd.) ("Premier"), acquired from the Republic of Tunisia a permit (the "Sbiba
Permit") for the exploration and production of oil and gas from a 4,936 square
kilometer (1,220,000 acres) area (the "Permit

                                       13
<PAGE>
 
Area") located in north-central Tunisia.  The respective participating interests
of the parties in the Permit Area are 50% ETAP, 32% ARCO, 10% Premier and 8%
LaTex Resources International.

          The seismic acquisition and processing and the geological and
geophysical evaluations of the Permit Area began in September 1993.  In July
1994, the initial well location was recommended and approved by the Sbiba
Operating Committee and wellsite preparation began.  The Sbiba #1, scheduled to
be drilled to a total depth of 2,500 meters (8,200 feet), was spudded on
November 9, 1994.  The well encountered unexpected and severe overpressure zones
in the Eocene Evaporites resulting in slower than expected drilling rates and
ultimately in having to drill a sidetrack hole at 1,343 meters (4,405 feet).  A
total depth of 2,076 meters (6,810 feet) was reached before having to suspend
operations on March 5, 1995 due to overpressure concerns and the presence of
natural gas in the wellbore.  The objective reservoir, the Albo-Aptian
carbonates, was never reached or evaluated and the well was temporarily
abandoned.  Subsequently, the operator of the project, in response to a request
from the Tunisian government, permanently plugged the well and restored the
drill site.

          ARCO and Premier have indicated their interest in terminating their
participation in the Permit.  The Company is currently seeking to locate new
participants to acquire the interests of ARCO and Premier.  No assurance can be
made that new participants willing to acquire the Arco and Premier interests
will be found.

          Since inception of the Tunisian project, approximately $13,168,000 has
been expended by the participants to date, of which LaTex Resources
International's share has been approximately $2,106,880.  The Company has
insufficient capital to continue its active participation in the project and,
effective July 31, 1996, the Company has written off its entire investment in
the Sbiba Permit in the amount of $2,491,299.

          Kazakhstan Prospect.  In April 1995, the Company's wholly-owned
          -------------------                                            
subsidiary, LaTex Resources International, agreed to participate, for a 25%
interest, in a production sharing service contract to rehabilitate divisions
three, four and eight of the Uzen oil and gas field located in the Republic of
Kazakhstan, C.I.S.  Pursuant to that agreement, the Company agreed to fund the
initial $2.5 million of capital on behalf of itself and Edco Drilling Company
("Edco").  The terms of the project were to provide for immediate cash flow to
the Company's interest.  Subsequently, Delcon Petroleum Development Kazakhstan
Limited, L.L.C. ("Delcon"), as operator, entered into a service contract with
Uzenmunaigas Production Association ("UMG") to carry out the work.  The
participants in the project, pursuant to an operating agreement signed in August
1995, include Delcon (47.5%), LaTex International (25%), and Petronet (27.5%).
The objective of the Uzen project was to repair, rework and recomplete inactive
oil and gas wells in the field utilizing western technology, expertise and
capital in order to restore or enhance production from the field.  In exchange
for providing these services and risk capital, UMG was to advance to the western
participants a total of 200,000 metric tons (1.5 million barrels) of crude oil
in two increments.  The proceeds from the sale of this crude was to be utilized
in the rehabilitation project.  In addition, the western participants were to
have received reimbursement of all capital costs and expenses.  UMG and the
western participants were to each retain a 50% interest in crude oil production
above a base line of approximately 30 barrels of oil per day per well.

          During the first quarter of fiscal 1996, the Company received written
notice from both Edco and Delcon that, in their view, the Company was in breach
of its agreement with Edco.  The Company strongly disagreed with Edco's position
since the Company was in compliance with the operating agreement governing the
project.  In addition, Delcon notified the Company that UMG would seek to
further alter the terms of the service contract in a manner which the Company
believed would be detrimental to the project's viability.  There has been no
further progress on, or correspondence between the Company and Delcon or Edco
regarding, the Uzen project since the second quarter of fiscal 1996.  There can
be no assurance that the uncertainties surrounding this project will be resolved
in a manner acceptable to the Company.

          Effective July 31, 1996, the Company has written off its entire
investment in the Uzen project in the amount of $955,496.

Reserves

          Lee Keeling and Associates, Inc. ("LKA"), the Company's independent
petroleum engineering consulting firm, has made estimates of the Company's oil
and gas reserves at July 31, 1996.  LKA's report covers the estimated present
value of future net cash flows before income taxes (discounted at 10%)
attributable to the Company's proved developed reserves, as well as its proved
undeveloped reserves and estimated future net cash flows therefrom.  The oil and
gas reserve and economic data presented below does not include small interests
owned by the Company in approximately 400 operated and non-operated, non-
strategic oil and gas properties which the Company has agreed to sell for
approximately $1.5 million, before adjustments.

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

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

          The following table sets forth estimates of the proved oil and natural
gas reserves of the Company at July 31, 1996, as evaluated by LKA.

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

         Estimates of the Company's proved reserves have never been filed or
included in reports to any federal authority or agency, other than the
Securities and Exchange Commission.

         For further information on reserves, costs relating to oil and gas
activities, and results of operations from producing activities, see Note 14 to

     The well information above excludes wells in which the Company has only an
overriding royalty interest.

     At July 31, 1996 the Company was not participating in the drilling or
completion of any oil and gas wells.

     All of the Company's drilling activities are conducted with independent
contractors.  The Company owns no drilling equipment.

Competition

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

     Increases in worldwide energy production capability and decreases in energy
consumption as a result of conservation efforts have brought about substantial
surpluses in energy supplies in recent years.  This, in turn, has resulted in
substantial competition for markets historically served by domestic natural gas
resources both with alternate sources of energy, such as residual fuel oil, and
among domestic gas suppliers.  As a result, there have been reductions in oil
and gas prices, widespread curtailment of gas production and delays in producing
and marketing gas after it is discovered.  Changes in government regulations
relating to the production, transportation and marketing of natural gas have
also resulted in significant changes in the historical marketing patterns of the
industry.  Generally, these changes have resulted in the abandonment by many
pipelines of long-term contracts for the purchase of natural gas, the
development by gas producers of their own marketing programs to take advantage
of new regulations requiring pipelines to transport gas for regulated fees, and
the emergence of various types of gas marketing companies and other aggregators
of gas supplies.  See "Item 1. Business and Item 2. Properties -Regulation."  As
a consequence, gas prices, which were once effectively determined by government
regulation, are now largely established by market competition.  Competitors of
the Company in this market include other producers, gas pipelines and their
affiliated marketing companies, independent marketers, and providers of
alternate energy supplies, such as residual fuel oil.

Regulation

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

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

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

                                       18

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

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

     Natural Gas Sales and Transportation.  Federal legislation and regulatory
     ------------------------------------                                     
controls have historically affected the price of the gas produced by the Company
and the manner in which such production is marketed.  The transportation and
sale for resale of gas in interstate commerce are regulated pursuant to the
Natural Gas Act of 1938 (the "NGA") and the Natural Gas Policy Act of 1978 (the
"NGPA") and Federal Energy Regulatory Commission ("FERC") regulations
promulgated thereunder.  Since 1978, maximum selling prices of certain
categories of gas, whether sold in interstate or intrastate commerce, have been
regulated pursuant to the NGPA.  The NGPA established various categories of gas
and provided for graduated deregulation of price controls of several categories
of gas and the deregulation of sales of certain categories of gas.  All price
deregulation contemplated under the NGPA has already taken place.

Title to Properties

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

Operational Hazards and Insurance

     The operations of the Company are subject to all risks inherent in the
exploration for and production of oil and gas, including such natural hazards as
blowouts, cratering and fires, which could

                                       19
<PAGE>
 
result in damage or injury to, or destruction of, drilling rigs and equipment,
formations, producing facilities or other property, or could result in personal
injury, loss of life or pollution of the environment.  Any such event could
result in substantial expense to the Company which could have a material adverse
effect upon the financial condition of the Company to the extent it is not fully
insured against such risk.  The Company carries insurance against certain of
these risks but, in accordance with standard industry practice, the Company is
not fully insured for all risks, either because such insurance is unavailable or
because the Company elects not to obtain insurance coverage because of cost.
Although such operational risks and hazards may to some extent be minimized, no
combination of experience, knowledge and scientific evaluation can eliminate the
risk of investment or assure a profit to any company engaged in oil and gas
operations.

Other Business

     The Company has invested in the development of certain other business
interests.  While the Company continues to believe these ventures have merit,
the Company has been unable, due to its own capital requirements, to provide
sufficient financial assistance and support to achieve its original objectives
in undertaking these investments.  The continued viability of these business
ventures is in jeopardy without the infusion of substantial additional capital.
As a result of the Company's own declining financial condition and its inability
to provide any further financial assistance to these ventures, the Company has
abandoned its efforts and written off its investments and loans with respect to
these businesses.  Under the terms of the proposed merger of the Company with
Alliance Resources Plc, the Company is required to dispose of its interests in
these ventures, provided that in making such disposition the Company is not
required to pay or mitigate any of the liabilities of these businesses.  The
Company has agreed to sell these business interests to Imperial Petroleum, Inc.,
an affiliate of the Company, for 100,000 shares of the Company's common stock.
Completion of the sale is subject to, among other things, the receipt of an
opinion from an independent investment banking firm as to the fairness of the
sale to the Company's stockholders.  Even in the event the proposed merger with
Alliance Resources Plc is not completed, the Company intends to proceed with the
sale of its interests in these ventures in order to refocus its efforts on its
core oil and gas business.  See "Proposed Merger With Alliance Resources Plc."

     Crude Oil Processing.  The Company owns 5,000,000 shares of common stock of
     --------------------                                                       
Wexford Technology, Incorporated ("Wexford") representing approximately 32% of
Wexford's issued and outstanding common stock.  In addition, the Company has an
agreement with Wexford that provides for the issuance of additional Wexford
shares to the Company as an incentive for providing certain loans to Wexford.
Wexford's wholly-owned subsidiary, Waste Conversion Corp. ("Waste Conversion"),
holds the exclusive license to certain proprietary microwave technology utilized
to reclaim crude oil from oilfield waste, including tank bottoms, to reform or
blend crude oils with varying gravities, to reduce paraffin content of waxy
crude oil and to remove naturally occurring radio active material from oil field
produced fluids.  Wexford is a development-stage company.  Through December
1993, the Company had invested in Wexford $943,577 for the construction of a
commercial crude oil blending and processing facility in Troy, Alabama utilizing
the proprietary processing technology.  The facility was substantially completed
in April 1992, at which time the Company concluded that the proprietary
technology for crude oil and tank bottoms processing required no further
research and development to meet all material functional and economic
requirements necessary for commercial exploitation.  The Company has
subsequently made additional loans to Wexford and Waste Conversion for operating
capital.

     The Alabama processing facility is not commercially active and Wexford and
Waste Conversion are seeking to raise additional debt or equity capital
necessary to begin full scale commercial operations.  Wexford and Waste
Conversion are currently in default with respect to various debt and other
obligations and have received numerous demands for payment and threats of
litigation.  Effective July 31, 1996 the Company has written off its entire
investment in and loans to Wexford and Waste Conversion in the total amount of
$2,372,752.

     Mining.  The Company owns 3,798,730 shares of the common stock of Imperial

Petroleum, Inc. ("Imperial") representing approximately 12% of Imperial's issued
and outstanding common stock.  Imperial's wholly-owned subsidiary, Ridgepointe
Mining Company, owns gold and copper mining claims in Arizona and participates
in a joint venture to explore and develop certain gold mining claims in Mexico.

                                       20
<PAGE>
 
     The Company's investment in Imperial and Ridgepointe consisted primarily of
loans for operating capital.  At present, Imperial is actively seeking to raise
additional debt or equity capital to fund its operations.  Imperial is currently
in default under its bank debt.  Effective July 31, 1996 the Company has written
off its entire investment in and loans to Imperial in the total amount of
$1,797,378.

Employees

     The Company employs a total of 30 people, including 20 people in its Tulsa,
Oklahoma office and one person in its Evansville, Indiana office, whose
functions are associated with management, operations, accounting and oil and gas
marketing.  The Company employs seven people in the Tensaw, Alabama office who
are lease operators in the Company's South Carlton field, and one field person
each in the states of Louisiana and Tennessee. The Company's other field
activities are accomplished through independent contractors.  The Company
believes its relations with its employees and contractors are excellent.

Item 3.  Legal Proceedings.

     Torch/Nuevo/Panda Litigation.  In connection with the Company's sale of its
     ----------------------------                                               
subsidiaries Panda Resources, Inc. and Richfield Natural Gas, Inc. in 1993, the
Company became a party to three different lawsuits.

     On October 10, 1994, Nuevo Liquids, Inc. ("Nuevo") filed a lawsuit against
the Company and its wholly-owned subsidiary, LaTex Petroleum Corporation ("LaTex
Petroleum") styled Nuevo Liquids, Inc. v. LaTex Resources, Inc. and LaTex
                   ------------------------------------------------------
Petroleum Corp., Case No. 94-049944, District Court of Harris County, Texas,
- ---------------                                                             
234th Judicial District.  Nuevo alleged that the Company and LaTex Petroleum had
refused to arbitrate certain disputes arising under the Stock Purchase Agreement
dated July 15, 1993 between Nuevo and Panda Resources, Inc. ("Panda"), pursuant
to which Panda sold to Nuevo its former wholly-owned subsidiary, Richfield
Natural Gas, Inc. ("Richfield").  Under the terms of the Stock Purchase
Agreement, the Company was the guarantor of Panda's obligations to Nuevo.  The
disputed issues between Nuevo and the Company related to a post-closing final
accounting and settlement statement by which the final purchase price under the
Stock Purchase Agreement was to be adjusted to reflect certain post-closing
costs and events.

     On October 12, 1994, Torch Energy Marketing, Inc. ("Torch") filed a lawsuit
against the Company and its wholly-owned subsidiary, LaTex Petroleum styled
Torch Energy Marketing, Inc. v. LaTex Resources, Inc. and LaTex Petroleum Corp.,
- ------------------------------------------------------------------------------- 
Case No. 94-050945, District Court of Harris County, Texas, 270th Judicial
District.  Torch alleged that the Company and LaTex Petroleum had refused to
arbitrate certain disputes arising under the Stock Purchase Agreement dated 
July 26, 1993, between Torch and LaTex Petroleum, pursuant to which the Company
sold to Torch its former wholly-owned subsidiary, Panda. The disputed issues
between Torch and the Company related to a post-closing final accounting and
settlement by which the final purchase price under the Stock Purchase Agreement
was to be adjusted to reflect certain post-closing costs and events. On 
January 6, 1995, the Company removed both the Nuevo and Torch lawsuits to the
United States District Court for the Southern District of Texas, Houston
Division, Case No. H-95-0029.

     On March 21, 1995, the Company filed a lawsuit against its former wholly-
owned subsidiary, Panda, styled LaTex Petroleum Corporation v. Panda Resources,
                                -----------------------------------------------
Inc., Case No. CJ-95-01302, in the District Court of Tulsa County, Oklahoma.
- ----                                                                         
The Company sought recovery of $163,191.16 plus interest and attorneys' fees,
for the sale of natural gas to Panda for the period from June 1993, through
March 1994.

     On December 7, 1995, the company entered into a Settlement Agreement (the
"Settlement") with Torch, Nuevo, Panda, Steve Wilson and Wilson, Tucker &
Associates to settle each of the referenced lawsuits.  Pursuant to the
Settlement, the company agreed (a) to pay Nuevo $20,000 on December 7, 1995, and
an additional $30,000 over the course of 90 days following execution of the
Settlement, and (b) to pay Torch $50,000 within one year of the Settlement, an
additional $50,000 within two years of the Settlement, and an additional
$150,000 within three years of the Settlement, together with interest in the
amount of $36,000.  To secure its obligation under the Settlement, the Company
stipulated to an agreed judgment in the amount of $1,000,000 (less any amounts
paid pursuant to the Settlement) upon the Company's

                                       21
<PAGE>
 
default of its obligations under the Settlement.  Torch, Nuevo and Panda agreed
to dismiss their respective claims against the Company arising from the
referenced litigation.  In addition, the Company agreed to assume and indemnify
Panda and Torch against all obligations and amounts owed under a May 2, 1989,
agreement (the "Dewey County Contract") between Panda and Northern Natural Gas
Company relating to the transportation of natural gas through a facility located
in Dewey County, Oklahoma.  The Company has subsequently been asked to indemnify
Torch with respect to claims brought against it by Northern in a lawsuit filed
March 7, 1996, as more fully discussed below.

     Northern Natural Gas Company v. LaTex Resources, Inc., Case No. 94-049766,
     -----------------------------------------------------                     
152nd District Court of Harris County, Texas.  On October 7, 1994, Northern
Natural Gas Company ("Northern") filed a lawsuit against the Company alleging
that the Company had breached two Firm Transportation Service Agreements dated
December 1, 1990, between Northern and Panda, a former wholly-owned subsidiary
of the Company.  Northern claimed damages, including damages for anticipatory
breach, in the amount of $1,600,000, plus other actual damages and interest.  
On June 6, 1996, Northern and the Company entered into a Settlement Agreement
pursuant to which (a) the Company issued to Northern 50,000 shares of the
Company's Series B Senior Convertible Preferred Stock which are convertible
(subject to adjustment) into 333,333 shares of the Company's common stock, and
(b) the Company agreed to pay Northern $465,000 in installments of $50,000 by
June 21, 1996, $150,000 by May 1, 1997, $125,000 by May 1, 1998, and $140,000 by
May 1, 1999.  An agreed judgment was entered in the case, but Northern has
agreed not to seek to enforce the judgment unless the Company defaults in its
payment obligations.  Once the required payments have been made, Northern has
agreed to execute a release of the judgment.

     Associated Storage Corp., formerly known as Centennial Storage Corp., a

Oklahoma.  On November 17, 1994, Associated Storage Corporation ("Associated")
filed a lawsuit against the Company alleging that the Company had breached a
July 21, 1993 agreement between Associated and the Company pursuant to which the
Company allegedly agreed to pay Associated $150,000 in connection with the sale
of the Company's former wholly-owned subsidiary, Panda Resources, Inc., and
Panda's wholly-owned subsidiary, Richfield Natural Gas, Inc.  Associated seeks
actual damages in the amount of $150,000, prejudgment interest, court costs and
attorneys' fees.

Each of these cases is a wrongful death or personal injury action arising out of
an accident which occurred at a heater-treatment unit on the Blowhorn Creek
Millerella Oil Unit lease in Lamar County, Alabama.  Germany Oil Company, a
wholly-owned subsidiary of the Company, is a working interest owner in the oil
and gas lease relevant to the case and, together with all other working interest
owners, is a named defendant.  Each plaintiff seeks damages in the amount of $25
million.  All three cases have been referred to Germany Oil Company's insurance
carrier for defense.  Each case is in the initial stages of discovery.

     Northern Natural Gas Company v. Torch Energy Advisors, Inc., Case No. 
     -----------------------------------------------------------             
96-12462, 269th Judicial District Court of Harris County, Texas.  On March 7, 
1996, Northern Natural Gas Company ("Northern") filed this lawsuit against Torch
Energy Advisors, Inc. ("Torch" for alleged breach of a May 2, 1989, agreement
(the "Dewey County Contract") between Torch, Panda Resources, Inc. ("Panda"),
and Northern relating to the transportation of natural gas through a facility
located in Dewey County, Oklahoma.  The Company has assumed the defense of this
matter pursuant to the indemnification agreement entered into as part of the
December 7, 1995, settlement among Torch, Panda and the Company discussed above.

     In addition to the foregoing litigation, the Company is a named defendant
in lawsuits, is a party in governmental proceedings and is subject to claims of
third parties from time to time arising in the ordinary course of business.
While the outcome of lawsuits or other proceedings and claims against the
Company cannot be predicted with certainty, management does not expect these
additional matters to have a material adverse effect on the financial position
of the Company.

Item 5.  Market for Registrant's Common Equity and Related Shareholder Matters.

Market Information and Dividends

     The common stock of the Company (i) is traded over-the-counter and quoted
on NASDAQ under the symbol "LATX" and (ii) until September 4, 1996, was listed
on the Pacific Stock Exchange under the symbol "LAT".  Effective September 4,
1996, the Company's common stock was delisted by the Pacific Stock Exchange as a
result of the failure of the minimum bid price for the common stock to meet the
Exchange's listing maintenance requirements.

     The following table sets forth, for the periods indicated, (i) the high and
low closing bid prices per share of common stock as quoted by NASDAQ, and (ii)
the high and low closing bid prices per share of common stock as reported on the
Pacific Stock Exchange.  Bid quotations represent quotations between dealers
without adjustment for retail mark-ups, mark-downs or commissions and may not
necessarily represent actual transactions.

(1)  Effective September 4, 1996, the Company's common stock was delisted by the
     Pacific Stock Exchange as a result of the failure of the minimum bid price
     for the common stock to meet the Exchange's listing maintenance
     requirements.

(2)  There was no trading activity in the Company's common stock on Pacific
     Stock Exchange during the fourth quarter of fiscal 1996 and, therefore, no
     price information for this period is available.

     No cash dividends have been declared by the Company's Board of Directors
during the Company's two most recent fiscal years. The Company does not
presently intend to declare or pay dividends on the common stock.  The terms of
the Company's existing bank credit facility do not permit the Company to pay
dividends on the common stock.  Payment of dividends in the future, if any, will
depend on applicable legal and contractual restrictions, as well as the
financial condition and requirements of the Company and general business
conditions.  The Company presently intends to use its available cash flow for
expansion of the Company's business, including acquisition, development and
enhancement of oil and gas properties.

Recent Sales of Unregistered Securities

     During the year ended July 31, 1996, the Company issued (i) effective 
March 12, 1996, 58,800 shares of its common stock to Princeton Otolaryngology
Retirement Trust, an entity controlled by Dr. Howard S. Farmer, in payment of
indebtedness of Wexford Technology, Incorporated in the amount of $23,520, and
(ii) effective June 27, 1996, 85,000 shares of its common stock to Thomas J.
Patrick in payment of indebtedness of Wexford Technology, Incorporated in the
amount of $37,000.  Following the year ended July 31, 1996 the Company issued a
total of 1,690,000 shares of its common stock to various officers and employees
as described in more detail at "Item 11. Executive Compensation -- Restricted
Stock Grants".  In each of the referenced transactions, an exemption from
registration was claimed under Section 4(2) of the Securities Act of 1933, as
amended, and regulations promulgated thereunder because no public offering was
involved and the securities were issued for investment and not with a view to
the distribution thereof.  No underwriter was involved in any of the referenced
transactions nor were any underwriting discounts or commissions paid.  Each
certificate representing shares issued in the referenced transactions bears a
restrictive legend and stop transfer instructions were entered on the Company's
stock transfer records with respect thereto.

Item 6.  Selected Financial Data.

     The selected historical financial information presented in the table below
for and at the end of each of the years ended July 31, 1992, 1993, 1994, 1995

included under "Item 8.  Financial Statements and Supplementary Data."

of Operations.

FASB Accounting Standards

     The Financial Accounting Standards Board ("FASB") has issued Statements of
Financial Accounting Standards No. 114 ("SFAS 114"), Accounting by Creditors for
Impairment of a Loan and No. 118 ("SFAS 118"), Accounting by Creditors for
Impairment of a Loan - Income Recognition and Disclosures.  In general, these
statements require that impaired loans be measured by creditors at the present
value of expected future cash flows discounted at the loan's effective interest
rate or at the loan's observable market price or the fair value of the
collateral if the loan is collateral dependent.  The Company has adopted SFAS
114 and 118 for the fiscal year ended July 31, 1996.

     FASB has issued Statement of Financial Accounting Standard No. 119 ("SFAS
119"), Disclosure about Derivative Financial Instruments and Fair Value of
Financial Instruments.  This statement generally requires disclosures about
amounts, nature and terms of derivative financial instruments.  The Company has
adopted SFAS 119 for the fiscal year ended July 31, 1996.

     FASB has issued Statement of Financial Accounting Standard No. 121 ("SFAS
121"), Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of.  This statement requires that long-lived assets and
certain identifiable intangibles to be held and used by an entity be reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.  If the sum of the
undiscounted future cash flows is less than the carrying amount of the asset, an
impairment loss is recognized.  This statement is effective for financial
statements for fiscal years beginning after December 15, 1995.  The Company
intends to adopt SFAS 121 for the fiscal year ending July 31, 1997.  The Company
expects the adoption of SFAS 121 will not have a material effect on its
financial statements.

     FASB has issued Statement of Financial Accounting Standard No. 123 ("SFAS
123"), Accounting for Stock-Based Compensation.  This statement establishes
financial accounting and reporting standards for stock-based employee
compensation plans.  This statement defines a fair value based method of
accounting for an employee stock option or similar equity instrument plan.
Under the fair value based method, compensation cost is measured at the grant
date based on the value of the award and is recognized over the service period,
which is usually the vesting period.  This statement is effective for
transactions entered into in fiscal years that begin after December 15, 1995.
The Company intends to adopt the disclosure requirements of SFAS 123 for the
fiscal year ending July 31, 1997.

Results of Operations

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

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

(1)  The Company's price hedging arrangements did not have a material effect on
     average prices for the year ending July 31, 1995.

(2)  After giving effect to the impact of the Company's price hedging
     arrangements with the Company's principal bank.  Without such hedging
     arrangements, the average sales prices for the year ended July 31, 1996
     would have been $15.73 for oil and $2.03 for gas.

     Relatively modest changes in either oil or gas prices significantly impact
the Company's results of operations and cash flow and could significantly impact
the Company's borrowing capacity.  Prices received by the Company for sales of
oil and natural gas have fluctuated significantly from period to period. The
Company's ability to maintain current borrowing capacity and to obtain
additional capital on attractive terms is substantially dependent on oil and gas
prices. Domestic spot oil prices have ranged from a low of approximately $11 per
barrel in July 1986 to a high of approximately $40 per barrel in October 1991,
with a current price of approximately $24 per barrel.  The fluctuations in oil
prices during these periods reflect market uncertainty regarding OPEC's ability
to control the production of its member countries, as well as concerns related
to the global supply and demand for crude oil.  Since the end of the Gulf War in
early 1991, crude oil prices have experienced continued weakness, primarily as a
result of OPEC's inability to maintain disciplined production quotas by member
countries and the uncertainty associated with Iraq's return to the crude oil
export market.  These factors continue to overhang the market and will create
significant price volatility for the foreseeable future.

     Natural gas prices received by the Company fluctuate generally with changes
in the spot market price for gas.  Spot market gas prices have generally
declined in recent years because of lower worldwide energy prices as well as
excess deliverability of natural gas in the United States.  However, natural gas
prices have rebounded recently and appear to be poised for further
strengthening. Domestic spot natural gas prices have ranged from a low of
approximately $0.90 per Mcf in January 1992 to a high of approximately $2.70 per
Mcf in April 1996, with a current price of approximately $2.10 per Mcf.
Environmental concerns coupled with recent increases in the use of natural gas
to produce electricity have combined to improve prices.  Under FERC Order 636,
U.S. pipelines have been made more accessible to both buyers and sellers of
natural gas and, as a result, natural gas will be able to more effectively
compete for market share with other end-use energy forms.  All of this suggests
a continued improvement in the demand for natural gas over the long term.

     Within the oil and gas business, it appears that the substantial
restructuring of the major and large independent companies is slowing.  The
merger activity of the 1980's has waned, and despite the continued exodus by
U.S. companies to international ventures, it appears that the mid-1990's will be
a "settling in" time for most companies.  Nevertheless, there remains a large
inventory of properties available for acquisition within the United States.
However, it is anticipated that as crude oil and natural gas prices stabilize
and strengthen, fewer companies will be inclined to sell their properties in the
future.

                                       27

     The Company's principal source of cash flow is the production and sale of
its crude oil and natural gas reserves, which are depleting assets.  Cash flow
from oil and gas sales depends upon the quantity of production and the price
obtained for such production.  Except as affected by the Company's current
commodity hedging arrangement, an increase in prices permits the Company to
finance its operations to a greater extent with internally generated funds.  A
decline in oil and gas prices reduces the cash flow generated by the Company's
operations, which in turn reduces the funds available for servicing debt,
acquiring additional oil and gas properties and exploring for an developing new
oil and gas reserves.

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

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

     .    During the period between July 31, 1992 and July 31, 1996, the Company
          completed 12 oil and gas property acquisitions that added substantial
          amounts of proved oil and gas reserves for a total expenditure of
          approximately $30.8 million.  As a result of these transactions, the
          Company's equivalent proved reserves increased approximately 560% in
          fiscal 1992, 125% in fiscal 1993, 58% in fiscal 1994, 3.5% in fiscal
          1995 and 68% in fiscal 1996, and the Company's oil and gas production,
          revenues, lease operating expenses, interest expense and net income
          have increased significantly.

     .    The Company acquired Panda Resources in February 1993 and subsequently
          sold Panda's gas marketing and storage operations in July 1993.

     .    In April 1995 the Company completed the acquisition of Germany Oil
          Company which approximately doubled the Company's oil and gas
          properties and added significantly to the Company's liabilities.  The
          acquisition was accounted for using the purchase method of accounting.
          In connection with this acquisition, the Company refinanced its senior
          debt, issued preferred stock and entered into hedging arrangements
          with respect to sales prices for its oil and gas production.

     .    In December 1995 the Company completed the sale of certain oil and gas
          properties it had acquired from Phillips Petroleum and Sackett Oil
          Company for approximately $2,857,275 net cash to the Company.

     .    In March 1995 the Company acquired Germany Oil Company in a purchase
          transaction.  The assets of Germany Oil consisted primarily of oil and
          gas properties.  In recording the transaction, the Company failed to
          allocate the purchase price to all assets acquired as required by
          generally accepted accounting principles.  During fiscal 1996 the
          Company, based on the reports of independent petroleum engineers,
          reallocated the adjusted purchase price as of the date of acquisition.
          Accordingly, the Company's consolidated financial statements for the
          year ended July 31, 1995 have been restated.

     Year ended July 31, 1996 Compared to year ended July 31, 1995.  Total
     -------------------------------------------------------------        
revenues from the Company's operations for the year ended July 31, 1996 were
$15,006,816 before reduction by $1,475,653 as a result of losses incurred from
the Company's oil and gas price hedging arrangements.  This compares to total
revenues of $10,442,679 for the year ended July 31, 1995, which includes hedging
gains of $157,301.  The increase is attributable to a 15% increase in oil and
gas prices and the inclusion of the oil and gas operations of the Company's
wholly-owned subsidiary, Germany Oil Company, for the full year ended July 31,
1996.  The increased revenues were partially offset by lower revenues from the
Company's crude oil marketing activities.

     Total operating expenses for the year ended July 31, 1996 were $17,926,639
compared to $11,559,488 for the same period a year earlier.  Lease operating
expense increased 20% to $6,608,089

                                       28
<PAGE>
 
compared to the prior year primarily as a result of including the full year of
operations of Germany Oil, while expenses associated with the Company's
marketing operations decreased $610,155 due to reduced oil and gas marketing
activity.

     Depreciation, depletion and amortization expense increased from $2,710,574
in fiscal 1995 to $4,705,912 in fiscal 1996 primarily as a result of the
acquisition of Germany Oil.

     General and administrative expenses for the year ended July 31, 1996 were
$2,893,146 compared to $2,736,261 for the prior year due to routine increases in
the Company's administrative expenses.

     The Company incurred dry hole costs of $2,630,541 during the year ended
July 31, 1996 which was principally due to the write-off of the Company's
investment in the Tunisian Prospect.  The Company also wrote off its investment
in the Kazakhstan Prospect in the amount of $955,496.  See "Item 1.  Business
and Item 2. Properties -- Exploration and Development".

     The Company's equity in the net losses of its unconsolidated affiliates,
Wexford Technology, Incorporated and Imperial Petroleum, Inc. was $298,839
during the fiscal year July 31, 1995.  The current year equity in the losses or
earnings from these unconsolidated affiliates was not subject to determination
by the Company and, therefore, is included in the write off of the investment in
and advances to these affiliates in the total amount of $4,184,881 for the
fiscal year ended July 31, 1996.  See "Item 1. Business and Item 2. Properties -
- - Other Business".

     The Company recognized gains on the sale of assets of $2,365,807 from the
disposition of non-strategic oil and gas properties during the fiscal year ended
July 31, 1996, an increase of $2,237,881 from the preceding year.

     The Company had a net loss from continuing operations for the year ended
July 31, 1996 of $8,420,401 ($0.50 per common share), compared to a net loss
from continuing operations of $2,491,342 ($0.15 per common share) for the year
ended July 31, 1995.  The increase in the net loss from continuing operations is
primarily a result of the write off of the cost of the Company's activities in
Tunisia and Kazakhstan (reflected as dry hole cost and abandonments), hedging
contract losses, and equity in losses and write-offs of investments in
affiliates.  These increases were partially offset by a gain on the sale of
assets.

     The Company also incurred additional losses of $1,810,382 from discontinued
operations in connection with litigation arising out of the sale of its Panda
subsidiary in July 1993.  As a result, the Company incurred a net loss of
$10,801,404 ($0.60 per common share) for the year ended July 31, 1996 compared
to a net loss of $2,624,142 ($0.15 per common share) for the prior year.

     Year ended July 31, 1995 compared to year ended July 31, 1994.  Total
     -------------------------------------------------------------        
revenues from the Company's operations for the year ended July 31, 1995 were
$10,442,679 compared to $12,085,364 for the year ended July 31, 1994.  The
decrease is primarily attributable to a 13% decrease in oil and gas prices which
also resulted in lower revenues from the Company's crude oil marketing
activities.  The reduced revenues were partially offset by an increase in oil
and gas sales volume as a result of the acquisition of Germany Oil Company
effective in April 1995.  However, oil and gas sales revenues for the fourth
quarter of fiscal 1995 increased 46% compared to revenues in the fourth quarter
of fiscal 1994 as a result of the acquisition of Germany Oil.  The Company
anticipates that oil and gas sales revenues will further increase in subsequent
quarters due to this acquisition.

     Total operating expenses for the year ended July 31, 1995 were $11,559,488
compared to $11,880,094 for the same period a year earlier.  Lease operating
expense increased nine percent to $5,264,858 compared to the prior year
primarily as a result of the acquisition of Germany Oil, while expenses
associated with marketing operations decreased $1,472,684 due to lower product
prices.

     Depreciation, depletion and amortization expense increased from $2,213,823
during fiscal 1994 to $2,710,574 during fiscal 1995 as a result of the
acquisition of Germany Oil and due to an increase in depletion rates as a result
of the year-end price impact on the Company's base of oil and gas reserves.

                                       29
<PAGE>
 
     General and administrative expenses for the year ended July 31, 1995 were
$2,736,267 compared to $2,496,567 for the prior period.  The increase was due to
increases in the Company's legal and accounting fees associated with the closing
of the acquisition of Germany Oil in April 1995.

     The Company incurred losses from unconsolidated affiliates of $298,839
during the current fiscal year, with $216,998 of the losses attributable to
Wexford Technology Incorporated, a development stage company engaged in the
crude oil tank bottoms business.  See "Item 1. Business and Item 2. Properties -
Other Business."

     The Company recognized gains on the sale of assets of $127,926 from the
disposition of non-strategic oil and gas properties during the fiscal year ended
July 31, 1995, a reduction from gains of $265,281 in the previous year.

     The Company had an after-tax net loss from continuing operations for the
year ended July 31, 1995 of $2,491,342 ($0.15 per common share) compared to a
net loss of $423,341 ($0.02 per common share) for the year.  The increase in the
net loss is a result of lower oil and gas prices and increased operating,
financing, professional, and amortization costs associated with the purchase of
Germany Oil.

     Year ended July 31, 1994 compared to year ended July 31, 1993.  Total
     -------------------------------------------------------------        
revenues from the Company's operations for the year ended July 31, 1994 were
$12,085,366 as compared to $11,477,045 for the year ended July 31, 1993.  The
increase in revenues is primarily due to the Swift Energy acquisition and
increased marketing margins from the sale of the Company's production in the
South Carlton field in Alabama which were offset partially by a reduction in
crude oil prices from $17.88 per barrel to $14.56 per barrel.

     Total operating expenses for the year ended July 31, 1994 were $11,880,094
compared to $11,934,000 for the same period a year earlier.  Lease operating
expense increased two percent to $4,840,000 compared to the prior year primarily
as a result of the acquisition of oil and gas properties from Swift Energy,
while expenses from marketing operations were up $476,410 due to increased
marketing efforts on the South Carlton field.

     Depreciation, depletion and amortization expense in fiscal 1994 decreased
to $2,213,823 from $2,899,459 for the comparable period a year ago due to
significant downward revisions of oil and gas reserves in July 1993 for the
Wheat field in Loving County, Texas and the Flora field wells in Madison County,
Mississippi.  Both of these properties were sold during the fiscal year with the
Company recording significant gains on sale.

     General and Administrative expenses for the year ended July 31, 1994 were
$2,496,567 compared to $2,560,000 for the prior period.  These expenses are
within 1% of the previous year's results reflecting the Company's commitment to
control overhead.

     The Company had an after-tax net loss from continuing operations for the
year ended July 31, 1994 of $423,341 ($0.02 per common share) compared to a net
loss of $190,147 ($0.01 per common share) for the same period a year ago.  The
Company wrote off its $222,918 investment in its Phoenix Metals, Inc. subsidiary
during fiscal 1994.  To date this subsidiary has been unable to obtain financing
to initiate operations.  The Company's equity in the net losses of its
unconsolidated affiliates was $216,998 during the current fiscal year, with
$174,050 of the losses attributable to Wexford Technology, Incorporated, a
start-up company engaged in the crude oil tank bottoms business.  See "Item 1.
Business and Item 2.  Properties --  Other Business."

     The Company recognized gains on the sale of assets of $392,592, primarily
from the sale of non-strategic oil and gas assets during the fiscal year ended
July 31, 1994, a reduction of $470,888 from the previous fiscal year which
included the settlement of a natural gas contract in that period.

     The net loss of the Company for the year ended July 31, 1994 was $423,341
($0.02 per common share) compared to net income of $906,839 ($0.06 per common
share) for the previous year.  The decrease in net income is a result of a
$1,882,685 net gain (after income taxes) resulting primarily from the sale of a
gas purchasing contract in the prior period in addition to the write off of
Phoenix Metals and the

                                       30

Company's share of the losses of the unconsolidated affiliates.

Capital Resources and Liquidity

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

     Historically, the Company's operating needs and capital expenditures have
been funded by borrowings under its bank credit facilities and cash flow from
operations.   As a result of significant capital expenditures since 1991, the
Company has experienced a decrease in its short-term liquidity and a decline in
its working capital.  In connection with the Company's acquisition of Germany
Oil in April 1995, the Company's new credit facility provided a source of long-
term financing.  As a result of the Germany Oil acquisition, the Company assumed
approximately $4.3 million in liabilities and accounts payable which created a
significant working capital deficit.  The Company immediately began a program
designed to reduce these liabilities through negotiated reductions in amounts
owed and term payments out of the Company's cash flow.  At July 31, 1996, the
Company had current assets of $4.2 million and current liabilities of $32.6
million which resulted in negative working capital of $28.4 million.  This
compares to the Company's current assets of $4.2 million and current liabilities
of $11.3 million, which resulted in negative working capital of $7.1 million, at
July 31, 1995.  The increase in the Company's working capital deficit during
fiscal 1996 is primarily due to the current liability classification at July 31,
1996 of all indebtedness of the Company to its principal bank (see "Financing
Arrangements"), additional litigation costs principally resulting from
discontinued operations of $1.8 million, and increases in royalty and vendor
payables in the amount of $1.8 million resulting from the Company's inability to
fund its current obligations due primarily to product hedging losses of $1.5
million.  These amounts were partially offset by an increase in oil and gas
receivables resulting from higher product prices of approximately $500,000.  The
long-term portion of the Company's debt to its principal bank was $20.6 million
at July 31, 1995.  At July 31, 1994, the long-term portion of the Company's debt
to its principal bank was $4.5 million and negative working capital was $1.11
million.  The decline in the Company's working capital during the last two years
is primarily the result of the Company's assumption of approximately $4.3
million of indebtedness associated with the acquisition of Germany Oil and the
continued funding of its international operations and two unconsolidated
affiliates.  Subject to the availability of capital, the Company intends to
continue to pursue its program to achieve an orderly liquidation of the Germany
Oil indebtedness.  There can be no assurance that, without an infusion of
additional debt or equity capital, the Company will be able to timely liquidate
these liabilities.  As part of the Company's effort to reduce its working
capital shortage, the Company has entered into the proposed merger transaction
with Alliance Resources Plc.  See "Item 1. Business and Item 2. Properties -
Proposed Merger with Alliance Resources Plc."

     For the year ended July 31, 1996, the Company's operating activities
resulted in positive cash flow of $3,359,885 compared to a positive cash flow of
$1,742,623 for the year ended July 31, 1995.  The improvement in cash flow is
due to additional cash provided by operating activities through increased
accounts payable and additional depreciation depletion and amortization.  For
the year ended July 31, 1994, the Company's operating activities resulted in a
positive cash flow of $951,001 compared to providing deficit cash flow of
$2,596,354 for the year ended July 31, 1993.

     Investing activities of the Company used $206,426 in net cash flow for the
year ended July 31, 1996 to fund the Company's oil and gas activities.
Investing activities of the Company used $16,750,182 in net cash flow for the
year ended July 31, 1995 compared to using $3,551,072 in net cash flow for the
year ended July 31, 1994.  The increase in investing activities in fiscal 1995
was primarily due to the drilling of the first exploration well on the Company's
Tunisian prospect.  Investing activities of the Company used $3,588,429 in net
cash flow for the year ended July 31, 1993.  The decrease in cash flow used in
investing activities during fiscal 1994 compared to fiscal 1993 was a result of
a reduced number of oil and gas property acquisitions by the Company.

     Financing activities used $3,448,351 in net cash flow for the year ended
July 31, 1996 compared to $15,113,389 provided in net cash flow for the year
ended July 31, 1995 and $1,665,499 provided for the year ended July 31, 1994.
The increase during fiscal 1996 was a result of the monthly amortization of the

                                       31
<PAGE>
 
Company's indebtedness to its principal bank and additional debt reduction upon
the sale of oil and gas properties.  The increase in fiscal 1995 compared to
fiscal 1994 was a result of the Company's new credit facility with Bank of
America associated with the Company's acquisition of Germany Oil Company in
April 1995.  As a result of the Company's default under certain provisions of
its credit facility with Bank of America, the Company does not currently
anticipate being able to increase its level of borrowing under such credit
facility.

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

     Since the Company is engaged in the business of acquiring producing oil and
gas properties, from time to time it acquires certain non-strategic and marginal
properties in some of its purchases.  A portion of the Company's on-going
profitability is related to the disposition of these non-strategic properties on
a regular basis.  The  Company expects to continue to pursue sales of these
types of properties in the future.  In most cases the revenue from these
properties is insignificant and in many cases does not exceed the lease
operating expense.  As a result, a portion of the Company's capital resources
are generated by the sale of assets from continuing operations.  Sales of non-
strategic and minor interests oil and gas properties accounted for $2,365,807 in
gains during fiscal 1996, $127,248 in gains during fiscal 1995, and $565,932 in
gains during fiscal 1994.  The Company expects to pursue a more aggressive
policy of disposition of oil and gas properties in fiscal 1997.  Additionally,
the Company incurred a loss in fiscal 1994 of $173,340 on the disposition of the
40,000 shares of Electric & Gas Technology, Inc. common stock acquired in 1991.

     Capital Expenditures.  The timing of most of the Company's capital
     --------------------                                              
expenditures is discretionary.  Currently there are no material long-term
commitments associated with the Company's capital expenditure plans.
Consequently, the Company has a significant degree of flexibility to adjust the
level of such expenditures as circumstances warrant.  The Company primarily uses
internally generated cash flow and proceeds from the sale of oil and gas
properties to fund capital expenditures, other than significant acquisitions,
and to fund its working capital deficit.  If the Company's internally generated
cash flows should be insufficient to meet its debt service or other obligations,
the Company may reduce the level of discretionary capital expenditures or
increase the sale of non-strategic oil and gas properties in order to meet such
obligations.  The level of the Company's capital expenditures will vary in
future periods depending on energy market conditions and other related economic
factors.  The Company anticipates that its cash flow will not be sufficient to
fund its domestic operations and debt service at their current levels for the
next year.  As a result, the Company anticipates that it will be necessary to
increase the level of sales of the Company's oil and gas properties or seek
additional equity capital, of which there can be no assurance.  The Company's
proposed merger with Alliance Resources Plc, if completed, would be a source of
such equity capital.  See "Item 1.  Business and Item 2. Properties - Proposed
Merger with Alliance Resources Plc."

     Substantially all of the Company's capital expenditures over its recent
history have been made to acquire oil and gas properties.  During fiscal 1993,
1994, 1995 and 1996, the Company made a number of significant acquisitions of
oil and gas properties.  During the year ended July 31, 1993, the Company
completed two acquisitions of oil and gas properties for a cost of approximately
$3,013,000.  During the year ended July 31, 1994, the Company completed one
acquisition of oil and gas properties for a cost of approximately $1,740,000.
During the year ended July 31, 1995 the Company completed the acquisition of
Germany Oil for a cost of approximately $18.1 million.  Subsequent to July 31,
1995, the Company participated with Oakland Petroleum Operating Company in the
acquisition of producing oil and gas properties from Sackett Oil Company and The
Prudential Insurance Company of America for a total purchase price of
$5,850,000, less adjustments.  The properties are located in Texas, Louisiana
and California.  Of the total purchase price, the Company paid $2,885,320 for
the properties located in Texas and Louisiana.  The Company provided Oakland a
loan in the principal amount of $2,300,000 to finance Oakland's purchase of the
properties.  This acquisition was funded through additional borrowings under the
Company's principal credit facility.  The Company's strategy is to continue to
expand its reserve base

                                       32
<PAGE>
 
principally through acquisitions of producing oil and gas properties.  As a
result, it is likely that capital expenditures will exceed cash provided by
operating activities in years where significant growth occurs in the Company's
oil and gas reserve base. In such cases, additional external financing is likely
to be required.

     The Company intends to continue its practice of reserve replacement and
growth through the acquisition of producing oil and gas properties, although at
this time it is unable to predict the number and size of such acquisitions, if
any, which will be completed.  The Company's ability to finance its oil and gas
acquisitions is determined by its cash flow from operations and available
sources of debt and equity financing.  Exclusive of potential acquisitions and
subject to the availability of capital, the Company presently anticipates
capital expenditures in fiscal 1997 of approximately $800,000 for oil and gas
property enhancement activities.

     Financing Arrangements.  Since July 31, 1991, the Company has made 12
     ----------------------                                               
acquisitions of oil and gas properties.  These acquisitions have been financed
primarily through borrowings under the Company's bank credit facilities and
through internal cash flow.  The Company's acquisition of Germany Oil Company,
including the cash portion of the purchase price paid by the Company for the
volumetric production payments and overriding interests acquired from ENPRO
Reserve Acquisition Corp. and the cash portion of the consideration paid by the
Company pursuant to the exchange offer, were financed through borrowings by the
Company under a credit facility pursuant to a Credit Agreement dated as of March
31, 1995 (the "Credit Agreement") between Bank of America, NT and SA ("Bank")
and the Company's wholly-owned subsidiaries, LaTex Petroleum, Germany Oil and
LaTex/GOC Acquisition ("Borrowers").  In addition, under the credit facility the
Company and the Borrowers refinanced the Company's then existing indebtedness to
the Company's former principal lender.  The Company and its wholly-owned
subsidiary, ENPRO, have guaranteed the obligations of the Borrowers under the
Credit Agreement.

     Under the Credit Agreement, the Bank agreed to make loans to the Borrowers
(i) in the amount of $23,000,000 (the "Acquisition Loan") for the purposes of
refinancing the Borrower's then existing indebtedness, partially funding the
acquisition of Germany Oil Company and for working capital, and (ii) in the
amount of $2,000,000 (the "Development Loan") for additional approved
development drilling, workover or recompletion work on oil and gas properties
mortgaged by the Borrowers to the Bank as security for the loans under the
Credit Agreement.  On July 31, 1996, the outstanding balance of the loans was
$22,206,707.

     Advances under the Credit Agreement maintained from time to time as a "Base
Rate Loan" bear interest, payable monthly, at a fluctuating rate equal to the
higher of (i) the rate of interest announced from time to time by the Bank as
its "reference rate", plus 1%, or (ii) the "Federal Funds Rate" (as defined in
the Credit Agreement) plus 1 1/2%.  Advances under the Credit Agreement
maintained from time to time as a "LIBO Rate Loan" bear interest, payable on the
last day of each applicable interest period (as defined in the Credit
Agreement), at a fluctuating rate equal to the LIBO Rate (Reserve Adjusted) (as
defined in the Credit Agreement) plus 2%.  As of July 31, 1996, all advances to
the Company under the Credit Agreement are maintained as LIBO Rate Loans which
currently bear interest at the annual rate of 7.5%.

     Principal on any loans under the Credit Agreement is currently repayable in
monthly installments of $322,500 (net of Oakland Petroleum's monthly principal
payment of $42,500) plus an additional payment equal to the positive difference,
if any, between the net proceeds from Borrower's oil and gas production (as
defined in the Credit Agreement) times a variable dedicated percentage (as
defined in the Credit Agreement) and the minimum monthly payment.  All unpaid
principal and accrued interest under the Credit Agreement is due March 31, 2000.

     The Company's indebtedness to the Bank under the Credit Agreement is
secured by mortgages on all of the Company's producing oil and gas properties
and pledges of the stock of the Company's subsidiaries, LaTex Petroleum, Germany
Oil Company, LaTex/GOC Acquisition and ENPRO.  On a semi-annual basis, the value
of the oil and gas properties securing loans under the Credit Agreement is
redetermined by the Bank based upon its review of the Company's oil and gas
reserves.  To the extent that the aggregate principal amount of all loans under
the Credit Agreement exceeds the collateral value

                                       33
<PAGE>
 
as determined by the Bank, the Company must either pay the Bank an amount
sufficient to eliminate such excess, or provide additional oil and gas
properties as security for the loans having a value satisfactory to the Bank.

     Under the Credit Agreement, the Company has also granted an affiliate of
the Bank an overriding royalty interest in all of the Company's existing
producing oil and gas properties, other than those situated in the State of
Oklahoma (the "Bank ORRI").  The Bank ORRI is 6.3% of Company's net revenue
interest in each property.  The Bank is not entitled to the Bank ORRI on any
property acquired after closing of the financing.  On the later to occur of (i)
March 31, 1998 or (ii) at such time as the Bank has received a 15% internal rate
of return on the $25,000,000 commitment amount under the Credit Agreement, the
Bank ORRI will be adjusted downward to 2.1%.

     As a condition to the Bank making the loans under the Credit Agreement, the
Company's subsidiary, LaTex Petroleum, has entered into hedging agreements
designed to enable the Company to obtain agreed upon net realized prices for the
Company's oil and gas production and designed to protect the Company against
fluctuations in interest rates with respect to the principal amounts of all
loans under the Credit Agreement.  Under the current hedging arrangements with
the Bank, the Company pre-sold certain volumes of its gas production for a three
year period beginning April 1, 1995 at a fixed price of $1.806 per MMBTU.  The
dedicated annual volumes for gas average 2,605,384 MMcf in fiscal 1996,
1,948,592 MMcf in fiscal 1997 and 1,115,296 MMcf in fiscal 1998.  In addition,
the Company placed a price "collar" on certain volumes of its oil production
between $16.50 per barrel and $19.82 per barrel.  The dedicated annual volumes
for oil average 324,288 Bbls in fiscal 1996, 279,828 Bbls in fiscal 1997 and
170,344 Bbls in fiscal 1998.  Interest rate protection was provided based on an
interest rate swap at 7.47%.  The effect of these hedging arrangements has been
to reduce the Company's working capital in fiscal 1996 by $1,979,956 as a result
of additional payments to the Bank above scheduled principal and interest
payments.  At July 31, 1996, the future impact of the hedging agreements are
anticipated to result in additional losses of $3,649,287 based upon the
prevailing commodity prices and interest rate at that time.  See "Inflation and
Pricing" and Note 15 to the Company's consolidated financial statements at 
Item 8.

     The Credit Agreement contains affirmative and negative covenants which
impose certain restrictions and requirements on the Company, including:
limitations on the amount of additional indebtedness the Company may incur;
prohibition against payment by the Company of cash dividends; requirements that
the Company maintains a current ratio (current assets to current liabilities) of
at least 1.0 to 1.0, tangible net worth of at least $5.0 million, no less than
$500,000 in cash equivalent investments on hand at any given time, and no less
than $500,000 in working capital; limitations on the ability of the Company to
sell assets or to merge or consolidate with or into any other person; and
requirements that the Company maintain a consolidated current ratio of at least
1.0 to 1.0 and consolidated tangible net worth of at least $10 million.

     During the year ended July 31, 1996, the Company was in violation of
various provisions of the Credit Agreement.  The Company has acknowledged to the
Bank these events of default and, pursuant to a Forbearance Agreement between
the Company and the Bank dated July 23, 1996, as amended, the Bank agreed to
delay enforcement of its rights under the Credit Agreement and related loan
documents as a result of these events of default until the earlier of November
29, 1996, the occurrence of any default by the Company under the terms of
Forbearance Agreement, the occurrence of any additional default by the Company
under the Credit Agreement, or the Company's cure of the defaults.  The Bank has
indicated its willingness to further amend the Forbearance Agreement to extend
its agreement to forbear any action on the Company's default through February
28, 1997.  Under the terms of the Forbearance Agreement, the Company agreed to
(a) obtain promissory notes from Imperial Petroleum, Inc. ("Imperial"), Wexford
Technology, Inc. ("Wexford"), and LaTex Resources International evidencing their
indebtedness to the Company at August 16, 1996 in the amounts of $677,705,
$1,372,799 and $3,363,000, respectively, (b) obtain from Imperial a lien on and
security interest in certain of Imperial's assets (subject to existing perfected
liens and security interests) to secure Imperial's indebtedness to the Company,
and (c) pay all unpaid overriding royalties due LaSalle Street National
Resources Corporation in three monthly installments, beginning August 1, 1996,
with interest at the Bank's prime rate plus two percent.

     In addition, in accordance with the requirements of the Forbearance
Agreement, the Company and Bank entered into Amendment No. 2 to Amended and
Restated Credit Agreement dated as of August 16,

                                       34
<PAGE>
 
1996 ("Amendment No. 2") pursuant to which each of the Borrowers and Guarantors
under the Credit Agreement granted Bank a security interest in substantially all
of their assets which had not otherwise been previously pledged to the Bank
under the Credit Agreement.  In addition, the Company granted to the Bank a
security interest in the indebtedness owed to the Company by Imperial, Wexford
and LaTex, together with a security interest in the collateral pledged to the
Company by Imperial to secure Imperial's indebtedness to the Company, which
consists primarily of unpatented mining claims in the states of Arizona and
Montana.  In addition, the Company granted the Bank a security interest in the
shares of common stock Wexford and Imperial owned by the Company.

     The Company has dedicated a significant portion of its available revenues
and cash flows to remaining current in its payment obligations to the Bank.  In
addition, proceeds from sales of oil and gas properties by the Company have been
used to further reduce the Company's indebtedness to the Bank, with only limited
amounts of such proceeds being made available to fund the Company's working
capital needs.  As a result, the Company continues to fall further behind in
making required payments to royalty owners and vendors.  The effect of the
continuation of this policy, over the long term, will be to increase the
Company's accounts payable while reducing its debt to the Bank.  Because the
level of required payments to the Bank remains constant over the term of the
Credit Agreement, the rate at which the Company's accounts payable deficit
increases will become greater with time and, ultimately may jeopardize certain
of the Company's oil and gas leases.

     The Company believes that its cash flow from operations will be
insufficient to meet its anticipated capital requirements for the foreseeable
future.  As a result, the Company will be required to increase the level of
sales of its oil and gas properties, seek additional equity capital, or
restructure its existing Credit Agreement with the Bank, none of which can be
assured.  However, because future cash flows and the availability of debt or
equity financing are subject to a number of variables, such as the level of
production and the prices of oil and gas, there can be no assurance that the
Company's capital resources will be sufficient to maintain current operations or
planned levels of capital expenditures.

Proposed Merger With Alliance Resources Plc

     As a result of the demands placed upon the Company by the Bank, the
Company's continuing working capital deficit, its deteriorating financial
condition and inability of the Company to raise additional debt or equity
capital, management of the Company, in the fourth quarter of fiscal 1996,
determined to seek an equity infusion through a strategic merger with a suitable
merger candidate.  Management's primary objective in seeking a merger partner
was to solve the working capital deficit of the Company through an equity
infusion while minimizing dilution to the shareholders.  Although the Company
considered several potential transactions, Alliance Resources Plc ("Alliance")
emerged as the candidate most likely to meet the objectives of the Company.
Subsequent to year end the Company agreed, subject to shareholder approval and
satisfaction of certain other conditions, to enter into an agreement pursuant to
which the Company will merge with Alliance.  It is anticipated that the merger
will provide the Company with sufficient capital resources to eliminate its
existing working capital deficit, refinance the Company's senior debt and
eliminate the hedging agreements, and provide development capital for
exploration of the Company's oil and gas properties.  In addition, the Company
believes that the combination of the two companies provides strategic benefits
to the Company important to its long term growth and the enhancement of
shareholder value.  Although Alliance's domestic oil and gas operations are
significantly smaller than the Company's, the Company believes that the merger
will enhance the overall financial strength of the Company and provide a stable
platform from which future growth can be achieved.  The strategic objectives of
the combined Company will be to continue a policy of structured and stable
growth in the domestic U.S. oil and gas sector while implementing projects in
Western Europe, the Middle East and the former Soviet Union.

     As a result of the refocus of the Company on its core oil and gas
operations and under the terms of the merger agreement with Alliance, the
Company has agreed to dispose of its interests in Wexford Technology, Inc.,
Imperial Petroleum, Inc., LaTex Resources International, Inc. and Phoenix
Metals, Inc.  Despite attempts by management to locate potential purchasers for
these business interests, the financial condition of these entities and
additional capital requirements to achieve stable operations and cash flow have
been significant impediments to their sale.  As a result, Imperial Petroleum,
Inc., an affiliate of the Company, has agreed to acquire the Company's interest
in these companies for 100,000 shares of the

                                       35
<PAGE>
 
Company's common stock.  Imperial is controlled by the Company's President and
largest stockholder, Jeffrey T. Wilson.  Mr. Wilson will contribute to Imperial
the 100,000 shares of the Company's common stock to be used by Imperial in
acquiring the Company's interest in these companies.  Prior to the completion of
the sale, the Company will obtain an opinion from an independent investment
banking firm as to the fairness of the transaction to its stockholders.  See
"Item 1. Business and Item 2. Properties --Proposed Merger with Alliance
Resources Plc."

Seasonality

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

Inflation and Prices

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

     In connection with the execution of the Credit Agreement with the Bank, the
company has entered into a crude oil and natural gas hedging arrangement
designed to enable the Company to receive a net realized price of not less than
$1.81 per MMBtu of natural gas and $16.50 per barrel of crude oil on sale of the
volumes of crude oil and natural gas set forth in the Credit Agreement.

     Prices obtained for oil and gas production depend upon numerous factors
that are beyond the control of the Company, including the extent of domestic and
foreign production, imports of foreign oil, market demand, domestic and world-
wide economic and political conditions, and government regulations and tax laws.
Prices for both oil and gas have fluctuated significantly in 1996 and 1995.  The
following table sets forth the average price received by the Company for each of
the last two years and the effects of the hedging arrangement described below.

</TABLE>

     The Company has entered into a master agreement to hedge the price of its
oil and natural gas.  The purpose of the hedging arrangement is to provide
protection against price drops and to produce a measure of stability in the
volatile environment of oil and natural gas spot pricing.  With respect to the
losses incurred by the Company as a result of this hedging arrangement, see
"Capital Resources and Liquidity -- Financing Arrangements".  The following
table provides a summary of the Company's financial contracts.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------



Board of Directors
LaTex Resources, Inc.
Tulsa, Oklahoma


We have audited the accompanying consolidated balance sheets of LaTex Resources,
Inc. and subsidiaries (the "Company") as of July 31, 1996 and 1995 and the
related consolidated statements of operations, stockholders' equity, and cash
flows for the years ended July 31, 1996, 1995, and 1994.  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 at 
July 31, 1996 and 1995 and the results of the Company's operations and its cash
flows for the years ended July 31, 1996, 1995, and 1994, in conformity with
generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern.  As discussed in Note 1 to
the consolidated financial statements, the Company has incurred a significant
net loss for the year ended July 31, 1996 and has working capital deficiencies
and consolidated tangible net worth deficiencies.  As discussed in Notes 1 and 5
to the consolidated financial statements, the Company was not in compliance with
certain financial covenants of its credit agreement with its primary lender at
July 31, 1996.  These factors raise substantial doubt about the Company's
ability to continue as a going concern. Management's plans in regard to these
matters are also described in Note 1.  The consolidated financial statements do
not include any adjustments that might result from the outcome of this
uncertainty and do not include any adjustments to the classification of assets
and liabilities that might result should the Company be unable to continue as a
going concern.

As discussed in Note 16, the consolidated financial statements as of and for the
year ended July 31, 1995 have been restated to correct the accounting for the
acquisition of Germany Oil Company.

                  Notes to Consolidated Financial Statements

                         July 31, 1996, 1995, and 1994



1.   ORGANIZATION, FINANCIAL CONDITION AND BUSINESS COMBINATIONS

     Organization - LaTex Resources, Inc. (the Company) is an oil and gas
     ------------
     company engaged in the acquisition of and enhancements to producing oil and
     gas properties. The Company's principal oil and gas production operations
     are conducted in Oklahoma, Texas, Louisiana, Mississippi and Alabama. The
     Company, until the fourth quarter of fiscal 1996, was also involved in the
     exploration and development of oil and gas prospects located in Tunisia and
     Kazakhstan, C. I. S.

     Financial Condition - The Company's aggressive policy of oil and gas
     -------------------
     property acquisitions, unsuccessful foreign oil and gas exploration and
     unsuccessful investments in their unconsolidated affiliates, along with
     substantial operating losses for the current and preceding two years, has
     resulted in a working capital deficit and non-compliance with certain loan
     covenants at July 31, 1996. (See Note 5)

     The items of non-compliance have not been waived by the lender for the year
     ended July 31, 1996 and the Company was operating under a "forbearance"
     agreement. The "forbearance period" was from July 26, 1996 to November 29,
     1996. The Company is currently seeking an extension of the forbearance
     agreement until such time as the proposed Alliance Resources Plc merger
     (See Note 17) can be consummated.

     The Company's financial statements for the year ended July 31, 1996 have
     been prepared on a going concern basis which contemplates the realization
     of assets and the settlement of liabilities and commitments in the normal
     course of business. The Company incurred a net loss of $10,230,783 for the
     year ended July 31, 1996 and as of July 31, 1996 has an accumulated deficit
     of $11,747,860 and a deficit working capital of $10,564,424.

     The Company expects to incur substantial expenditures to develop its
     undeveloped reserves and acquire additional producing oil and gas
     properties, however, without raising additional capital the Company will be
     unable to achieve its business objective or reduce its working capital
     deficit. Management plans for raising additional capital include
     consideration of alliances or other partnership arrangements or potential
     merger opportunities.

     The Company has retained investment banking counsel to advise it on the
     possible sale of equity securities as well as to introduce and assist in
     the evaluation of potential merger and partnering opportunities. Management
     expects that these efforts will result in the introduction of other parties
     with interests and resources which may be compatible with that of the
     Company. See Note 17 regarding proposed transaction with Alliance Resources
     Plc. No assurances can be given that the Company will be successful in
     raising additional capital or consummating a business alliance. Further,
     there can be no assurance assuming the Company successfully raises
     additional funds or enters into a business alliance, that the Company will
     achieve profitability or positive cash flow.

1.   ORGANIZATION, FINANCIAL CONDITION AND BUSINESS COMBINATIONS (continued)

     Disposition of Panda Resources, Inc. and Its Wholly Owned Subsidiary
     --------------------------------------------------------------------
     Richfield Natural Gas, Inc., July 1993
     -------------------------------------- 

     In July 1993 the Company sold its wholly owned subsidiary, Panda Resources,
     Inc., and Panda's wholly owned subsidiary, Richfield Natural Gas, Inc.
     Final post closing adjustments were in dispute until December 1995 when a
     settlement agreement by the various parties resulted in a judgment against
     LaTex Resources, Inc. in the amount of $1,810,382. This amount is reflected
     in the 1996 consolidated financial statement as a loss on disposal of
     discontinued subsidiaries.

     Proceeds from Private Placement

     Acquisition of Germany Oil Company
     ----------------------------------

     Effective March 31, 1995 through a series of transactions, the Company
     acquired all of the issued and outstanding stock of Germany Oil Company
     ("Germany") in exchange for 250,000 and 11,800 of the Company's common and
     Series A Convertible Preferred Stock, respectively. The ratio of the number
     of shares received by the stockholders of Germany was determined through
     arms length negotiations between the Chairman of the Board and President of
     the Company and the President of Germany. The Company also issued 370,000
     shares of the Series B Convertible Preferred Stock and $8,900,000 in cash
     to retire a volumetric production payment and acquire all of the related
     contract rights mortgages, vendor liens and security interests. In
     addition, the Company paid $1,742,294 in cash, issued 482,201 shares of its
     Series A Convertible Preferred Stock and $87,998 in notes payable to
     acquire and retire certain indebtedness of Germany. The transaction was
     accounted for as a purchase. The fair value of assets and liabilities of
     Germany at date of acquisition follows:

                   Notes to Consolidated Financial Statements

                         July 31, 1996, 1995, and 1994


2.   SUMMARY OF ACCOUNTING POLICIES

     A summary of the significant accounting policies consistently applied in
     the preparation of the accompanying consolidated financial statements is as
     follows.

     Principles of Consolidation
     ---------------------------

     The consolidated financial statements include the accounts of the Company
     and its wholly owned subsidiaries. All significant intercompany accounts
     have been eliminated in consolidation.

     Inventories
     -----------

     Included in inventories at July 31, 1996 and 1995 are crude oil inventories
     at market value of $175,493 and $90,976, respectively.

     Accounting Estimates
     --------------------

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

     Financial Instruments
     ---------------------

     The fair value of current assets and current liabilities are assumed to be
     equal to their reported carrying amounts due to the short maturities of
     these financial instruments. Due to the Company's financial position, it is
     not practicable to estimate the fair value of the Company's long-term debt;
     additional information pertinent to its value is provided in Note 5 to the
     consolidated financial statements.

     The Company is required, by agreement with its primary lender (Bank of
     America), to participate in various hedging programs, executed by Bank of
     America, to protect against fluctuations in oil gas prices and interest
     rates. See Note 15 for discussion of the fair market value of these
     contracts.

     The carrying value of all other financial instruments approximates fair
     value.

                         July 31, 1996, 1995, and 1994


2.   SUMMARY OF ACCOUNTING POLICIES (continued)

     Concentrations of Credit Risk
     -----------------------------

     Financial instruments that potentially subject the Company to significant
     concentrations of credit risk consist principally of cash investments and
     accounts receivable. The Company places its cash investments with high
     quality financial institutions and limits the amount of exposure to any one
     institution. In the case of default of any one financial institution, no
     cash investments exist that are not covered by the FDIC. The Company's
     revenues are derived principally from uncollateralized sales to customers
     in the oil and gas industry. The concentration of credit risk in a single
     industry affects the Company's overall exposure to credit risk because
     customers may be similarly affected by changes in economic and other
     conditions. The Company has not experienced significant credit losses on
     such receivables. The Company performs periodic evaluations of its
     customers' financial condition and generally does not require collateral.

     Revenue Recognition
     -------------------

     The Company recognizes oil and gas production and gas marketing revenue in
     the month of sale. Uncollected revenue is accrued based on known facts and
     trends of the relevant oil and gas properties on a monthly basis.

     Property, Equipment, Depreciation and Depletion
     -----------------------------------------------

     The Company uses the successful efforts method to account for costs in the
     acquisition and exploration of oil and natural gas reserves. Costs to
     acquire mineral interests in proved reserves, and to drill and equip
     development wells are capitalized. Geological and geophysical costs and
     costs to drill exploratory wells which do not find proved reserves are
     expensed. Undeveloped oil and gas properties which are individually
     significant are periodically assessed for impairment of value and a loss is
     recognized at the time of impairment by providing an impairment allowance.
     The remaining unproved oil and gas properties are aggregated and an overall
     impairment allowance is provided based on Company experience. Depletion and
     depreciation are calculated on the units of production method based upon
     current estimates of oil and gas reserves provided by management.

     Non oil and gas property and equipment are stated at cost. Depreciation is
     computed by the straight-line method over the estimated useful lives of non
     oil and gas assets. Expenditures which significantly increase values or
     extend useful lives are capitalized. Expenditures for maintenance and
     repairs are charged to expenses as incurred. Upon sale or retirement of
     property and equipment, the cost and related accumulated depreciation and
     depletion are eliminated from the respective accounts and the resulting
     gain or loss is included in current earnings.

     Intangible Assets
     -----------------

     Intangible assets consist primarily of debt issuance costs. Debt issuance
     costs are amortized over the term of the related debt.

                         July 31, 1996, 1995, and 1994


2.   SUMMARY OF ACCOUNTING POLICIES (continued)

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

     Deferred tax assets and liabilities are recognized for the estimated future
     tax consequences attributable to differences between the financial
     statement carrying amounts of existing assets and liabilities and their
     respective tax bases. Deferred tax assets and liabilities are measured
     using enacted tax rates in effect for the year in which those temporary
     differences are expected to be recovered or settled. The effect on deferred
     tax assets and liabilities of a change in tax rates is recognized in income
     in the period that includes the enactment date.

     Gas Balancing
     -------------

     The Company follows the sales method of accounting for gas imbalances. A
     liability is recorded only if the Company's excess takes of natural gas
     volumes exceed its estimated remaining recoverable reserves. No receivables
     are recorded for those wells when the Company has taken less than its
     ownership share of gas production.

     Earnings Per Common Share
     -------------------------

     Earnings per common share is computed based upon the weighted average
     common shares outstanding. Outstanding stock options and warrants of LaTex
     Resources are excluded from the weighted average shares outstanding since
     their effect on the earnings per share calculation is immaterial or
     antidilutive.

     FASB Accounting Standards
     -------------------------

     The Financial Accounting Standards Board has issued Statement of Financial
     Accounting Standards No. 119 (SFAS 119), Disclosure about Derivative
     Financial Instruments and Fair Value of Financial Instruments. This
     Statement generally requires disclosures about amounts, nature, and terms
     of derivative financial instruments. The Company has adopted SFAS 119 for
     the fiscal year ended July 31, 1996.

     The Financial Accounting Standards Board has issued Statement of Financial
     Accounting Standards No. 121 (SFAS 121), Accounting for the Impairment of
     Long-Lived Assets and for Long-Lived Assets to be Disposed of. This
     Statement requires that long-lived assets and certain identifiable
     intangibles to be held and used by an entity be reviewed for impairment
     whenever events or changes in circumstances indicate that the carrying
     amount of an asset may not be recoverable. If the sum of the undiscounted
     future cash flows is less than the carrying amount of the asset, an
     impairment loss is recognized. This Statement is effective for financial
     statements for fiscal years beginning after December 15, 1995. The Company
     intends to adopt SFAS 121 for the fiscal year ending July 31, 1997. The
     Company expects the adoption of SFAS 121 will not have a material effect on
     its financial statements.

2.   SUMMARY OF ACCOUNTING POLICIES (continued)

     The Financial Accounting Standards Board has issued Statement of Financial
     Accounting Standards No. 123 (SFAS 123), Accounting for Stock-Based
     Compensation. This Statement establishes financial accounting and reporting
     standards for stock-based employee compensation plans. This Statement
     defines a fair value based method of accounting for an employee stock
     option or similar equity instrument plan. Under the fair value based
     method, compensation cost is measured at the grant date based on the value
     of the award and is recognized over the service period, which is usually
     the vesting period. This Statement is effective for transactions entered
     into in fiscal years that begin after December 15, 1995. The Company
     intends to adopt the disclosure requirements of SFAS 123 for the fiscal
     year ending July 31, 1997.

     Reclassification
     ----------------

     Certain amounts in the 1995 and 1994 consolidated financial statements have
     been reclassified to conform with the 1996 presentation.

3.   ACCOUNTS AND NOTES RECEIVABLE AND INVESTMENTS IN AND ADVANCES TO AFFILIATES

     The non-interest bearing note receivable from Oakland Petroleum Operating,
     Inc. (Oakland) represents the balance due to the Company for a loan entered
     into with the Company's primary lender for a joint purchase of property.
     The original amount was approximately $2,300,000 of which $1,267,500 was
     still outstanding at July 31, 1996. The note receivable is offset by a
     comparable amount included in the Company's long-term debt. Oakland pays
     all principal and interest payments directly to the Company's primary
     lender.

 4.  INCOME TAXES (continued)

     A valuation allowance is required when it is more likely than not that all
     or a portion of the deferred tax assets will not be realized. The ultimate
     realization of the deferred tax assets is dependent upon future
     profitability. Accordingly, a valuation allowance has been established to
     reduce the deferred tax assets to a level which, more likely than not, will
     be realized.

     The Company has net operating loss (NOL) carryforward to offset its
     earnings of approximately $11,390,000. Additionally, approximately
     $10,490,000 of NOL carryforwards are available to offset the future
     separate company earnings of Germany. If not previously utilized, the net
     operating losses will expire in varying amounts from 2006 to 2011.

     (A)  Note payable dated April 18, 1995, for $23,000,000 with option of an
          additional $2,000,000 for six months for approved workovers,
          recompletions and development drilling of specified reserves.
          Principal due monthly of $365,000 including Oakland Petroleum Co.
          payment of $42,500 monthly. Interest due monthly at the higher of a
          Base Rate (the higher of the Bank of America Reference Rate and the
          Federal Fund Rate plus .5% per annum) plus 1% per annum and the London
          Interbank Offered Rate plus 2%. The current rate at July 31, 1996 was
          7.469%. Matures March 30, 2000. Amounts outstanding are secured by
          mortgages which cover certain of the Company's oil and gas properties.

     The Company's existing debt agreements contain certain covenants, including
     maintaining a positive current ratio of 1.0, excluding current portion of
     long-term debt, maintaining a minimum tangible net worth of $10,000,000,
     maintaining a minimum cash or cash equivalents balance of $500,000,
     maintaining working capital of at least $500,000, the negative covenant
     related to permitted investments, and the covenant relating to default on
     other indebtedness in excess of $50,000.

 5.  NOTES PAYABLE (continued)

     The Company was not in compliance with the current ratio, cash equivalent,
     minimum tangible net worth, and working capital covenants at July 31, 1995.
     The items of non-compliance were subsequently waived by the lender for the
     year ended July 31, 1995 and through January 31, 1996. The Company was not
     in compliance with the above noted covenants at July 31, 1996 and was
     operating under a "forbearance" agreement discussed in Note 1 to the
     financial statements. The "forbearance" agreement expired on November 29,
     1996 and the bank has not extended the agreement. The debt agreement
     contains various acceleration provisions of the due date in the event of
     non-compliance. Accordingly, the entire unpaid balance has been classified
     as a current liability at July 31, 1996.

 6.  WRITE OFFS

     Investments
     -----------

     During the fourth quarter of fiscal 1996, the Company wrote off its
     investments in Wexford Technology, Incorporated (Wexford) and Imperial
     Petroleum, Inc. (Imperial). The Company has not been able to obtain
     reliable current financial information, accordingly, summarized financial
     information is not presented.

     The Company acquired 32.3% of Wexford through a series of transactions
     culminating in May 1994. During the fourth quarter fiscal 1996, the Company
     recorded a charge to earnings of $2,372,752 to write off its investment.
     Wexford is presently in default on its bridge debt and has received
     numerous written demands for payment and correspondence threatening
     litigation. Included in the write off was $1,462,765 in notes receivable.

     The Company owns 12% of the common stock of Imperial and certain officers,
     directors and employees of the Company own 28.8%. During the fourth quarter
     of fiscal 1996, the Company recorded a charge to earnings of $1,797,378 to
     write off this investment. Imperial is currently in default on its bank
     debt. Included in the write off of the Company's investment was $722,603 in
     notes receivable.

     Wexford and Imperial are both development stage enterprises that are
     seeking capital infusion to complete their facilities and achieve
     commercial operations. Neither Wexford nor Imperial have been able to raise
     additional debt or equity capital. Further, there can be no assurance,
     assuming Wexford and Imperial successfully raise additional funds or enter
     into a business alliance, that they will achieve commercial operations or
     positive cash flow.
 
     Exploration Prospects
     ---------------------

     During the fourth quarter of fiscal year 1996, the Company recorded a
     charge to earnings of $955,496 to write off costs incurred in connection
     with a venture in Kazakhstan C.I.S. Subsequent to July 31, 1996, the
     Company received written notice that the Company may be in breach of its
     agreements related to the venture. The Company believes it is in
     substantial compliance with the operating agreement governing the project.
     In addition, the Company has been notified that Uzenmunaigaz, the regional
     production association for the Middle Caspian Basin, may seek to further
     alter the terms of a contract in a manner which the Company believes would
     be detrimental to the project's viability.

 6.  WRITE OFFS (continued)

     During fiscal 1993 the Company, through a subsidiary, acquired an interest
     in a permit granted by the Republic of Tunisia for the exploration and
     production of oil and gas from a 4,936 square kilometer (1,220,000 acres)
     area located in north-central Tunisia. Initial seismic acquisition
     activities began in 1994. The first exploratory well was spudded in fiscal
     1995. This well was drilled and temporarily abandoned prior to reaching the
     objective depth.

     In fiscal 1996, the operator of the project, in response to a request from
     the Tunisian government, permanently plugged the well and restored the well
     site. The Company has insufficient capital to continue the project and, due
     to the limited time remaining on the exploration permit, decided to abandon
     the project and write off its investment.


  7. SAVINGS AND PROFIT SHARING PLAN

     The Company maintains an employee savings and profit sharing plan (the
     Plan) which covers substantially all of its employees. The Plan is
     comprised of a 401(k) savings portion and a noncontributory defined
     contribution portion. Employees are qualified to participate after
     approximately one year of service. Participation in the 401(k) plan is
     voluntary, and the Company matches contributions up to four percent of the
     employees' salary at a rate of 33 1/3 percent of the employee's
     contribution. Employees are allowed to contribute the maximum amount
     allowed by the Internal Revenue Code each year, subject to
     nondiscrimination rules.

     The noncontributory defined contribution portion of the Plan allows the
     Company to share annual profits with employees. Annual payments to the Plan
     are elective. Management elected to make no contributions to the Plan for
     1996, 1995, or 1994. The Company is under no obligation to make
     contributions to the Plan in the future.


  8. STOCK OPTIONS

     Stock Option Plan
     -----------------

     The 1993 Incentive Stock Plan (the "Plan") was effective December 8, 1993.

     The Plan is administered by a Compensation Committee consisting of not less
     than three members of the Board of Directors and a special committee
     appointed by the Board of Directors, as necessary.

     The aggregate number of shares of the Company's Common Stock issuable under
     the Plan is 2,000,000. Such stock will be made available from the Company's
     authorized but unissued Common Stock or from Stock held as Treasury Stock.

  8. STOCK OPTIONS (continued)

     Options and Appreciation Rights
     -------------------------------

     This Plan authorizes the Committee to grant to key employees options to
     purchase the Company's Common Stock which may be in the form of incentive
     stock options ("ISO's"), or in the form of non-statutory options ("Non-
     Statutory Options"). The term of each option shall be for such period as
     the Committee determines but no longer than ten years from the date of
     grant or five years to an individual who is a 10% stockholder of the
     Company.

     The aggregate fair market value exercisable by an individual optionee
     during any calendar year under all stock option plans of the Company may
     not exceed $100,000. The exercise price per share for the Common Stock
     covered by any Options shall be determined by the Committee and, provided
     that in the case of an ISO and the per share exercise price shall be not
     less than the fair market value (or in the case of an ISO granted to an
     individual who at the time is a 10% Stockholder, 110% of the fair market
     value) of one share of Common Stock. Options to purchase 1,690,000 shares
     of common stock were granted under the Plan. (See Note 17)

     Restricted Stock Awards
     -----------------------

     The Plan authorizes the Committee to grant restricted Common Stock
     ("Restricted Stock") to key employees. The Committee may designate a
     restriction period with respect to such shares of not less than one year
     but not more than five years (the "Restriction Period") during which an
     employee will not be permitted to sell, transfer, pledge or assign shares
     of Restricted Stock awarded to him, provided that within such limitations,
     the Committee may provide for the lapse of such restrictions installments
     where deemed appropriate. Upon termination of employment during the
     Restriction Period for any reason, all shares of Restricted Stock with
     respect to which restrictions have not yet expired will be forfeited by the
     employee and returned to the Company.

     The Plan also authorizes the Committee to award tax gross-up rights which
     entitle the grantee to cash payments from the Company at such time as
     income and/or excise tax liabilities arise with respect to grants under the
     Plan. Tax gross-up rights may be granted coincident with or after the date
     of grant of the related Option or Restricted Stock awards. No restricted
     shares have been issued at July 31, 1996. (See Note 17)

 9.  WARRANTS

     As of July 31, 1996, the Company, in connection with the sale of previously
     unissued common stock, has 2,700,000 Warrants outstanding. The sale
     included 2,587,500 of the Warrants which were detachable from the
     Stock/Warrant Units upon issuance and trade separately from the Units and
     Common Stock. Unless exercised, the 2,587,500 Warrants automatically expire
     on November 19, 1997. Pursuant to the terms of the Warrants, the Board of
     Directors of the Company may reduce the exercise price, $4.25, of the
     Warrants and may also extend the period during which the Warrants may be
     exercised. The Warrants may be redeemed by the Company at a price of $0.01
     per Warrant with 30 days prior written notice by the Company.

                         July 31, 1996, 1995, and 1994

 9.  WARRANTS (continued)

     In addition, the Company issued Warrants to the underwriter of the offering
     for $.01 per Warrant (underwriter Warrants) to purchase up to 112,500 units
     for $4.44 per unit. These Warrants are exercisable, in part or whole, until
     November 16, 1997. The Company also has agreed to register, at its sole
     cost and expense, all or a portion of the underwriter Warrants and/or the
     shares issuable, upon the exercise of the Warrants during the period
     November 10, 1993 to November 16, 1997.

     The Company has also issued 1,516,000 private Warrants, exercisable at a
     price ranging from $.75 to $3.25 at a ratio of 1 to 1. These Warrants
     expire at various dates from January 26, 1997 to October 31, 2001.

10.  PREFERRED STOCK

     The Board of Directors has the authority to issue 5,000,000 shares of
     Preferred Stock, in one or more series, and to fix the rights, preferences,
     qualifications, privileges, limitations or restrictions of each such series
     without any further vote or action by the shareholders, including the
     dividend rights, dividend rate, conversion rights, voting rights, terms of
     redemption (including sinking fund provisions), redemption price or prices,
     liquidation preferences and the number of shares constituting any series or
     the designations of such series.

     The Company's Series A Convertible Preferred Stock (i) pays annual
     dividends at the rate of $0.20 per share payable quarterly in cash (or, if
     payment of cash dividends is prohibited by the Company's senior lender,
     payable in additional shares of Series A Convertible Preferred Stock), (ii)
     has no voting rights except as otherwise required under Delaware law, (iii)
     has a liquidation preference over shares of the Company's common stock of
     $10.00 per share plus accrued and unpaid dividends, (iv) is redeemable at
     the option of the Company at a redemption price of $10.00 per share plus
     accrued and unpaid dividends, (v) is convertible by the holder into shares
     of the Company's common stock at a conversion price of $3.33 per share, and
     (vi) has piggyback registration rights in the event the Company seeks to
     make a registered public offering of its common stock. There are 451,097
     and 442,281 shares of Series A Convertible Preferred Stock outstanding at
     July 31, 1996 and 1995, respectively.

     The Series B Convertible Preferred Stock (i) pays annual dividends at the
     rate of $1.20 per share payable quarterly in cash (or, if payment of cash
     dividends is prohibited by the Company's senior lender, payable in
     additional shares of Series B Convertible Preferred Stock), (ii) has no
     voting rights except as otherwise required under Delaware law, (iii) has a
     liquidation preference over shares of the Company's Series A Convertible
     Preferred Stock and the Company's common stock of $10.00 per share plus
     accrued and unpaid dividends, (iv) is redeemable at the option of the
     Company at a redemption price of $10.00 per share plus accrued and unpaid
     dividends, and (v) is convertible by the holder into shares of the
     Company's common stock at an initial conversion price of $1.50 per share,
     subject to adjustment from time to time to prevent dilution. By separate
     agreement, the Company has granted certain demand registration rights and
     piggyback registration rights in the event the Company seeks to make a
     registered public offering of its common stock. There are 479,345 and
     381,100 shares of Series B Convertible Preferred Stock outstanding at July
     31, 1996 and 1995, respectively.

11.  LITIGATION, COMMITMENTS AND CONTINGENCIES

     Litigation - In connection with the Company's sale of its subsidiaries,
     ----------
     Panda Resources, Inc. and Richfield Natural Gas, Inc. in 1993, the Company
     became a party in three different lawsuits.

     On December 7, 1995, the Company entered into a Settlement Agreement (the
     "Settlement") to settle all matters related to the sale and the related
     litigation. Pursuant to the Settlement, the Company agreed to pay to the
     plaintiffs (a) $20,000 on December 7, 1995, and an additional $30,000 over
     the course of 90 days following execution of the Settlement, and (b) to pay
     $50,000 within one year of the Settlement, an additional $50,000 within two
     years of the Settlement, and an additional $150,000 within three years of
     the Settlement, together with interest in the amount of $36,000. To secure
     its obligation under the Settlement, the Company stipulated in an agreed
     judgment that it would be liable in the amount of $1,000,000 (less any
     amounts paid pursuant to the Settlement) upon the Company's default of its
     obligations under the Settlement. In addition, the Company agreed to assume
     and indemnify the plaintiffs against all obligations and amounts owed under
     a May 2, 1989 agreement between Panda and Northern Natural Gas Company
     relating to the transportation of natural gas through a facility located in
     Dewey County, Oklahoma. Pursuant to this indemnification, the Company has
     been asked to indemnify one of the plaintiffs with respect to claims
     brought against it by Northern in a lawsuit filed March 7, 1996, as more
     fully discussed below.

     March 7, 1996, Northern Natural Gas Company ("Northern") filed a lawsuit
     against Torch Energy Advisors, Inc. ("Torch") for alleged breach of a May
     2, 1989 agreement (the "Dewey County Contract") between Torch, Panda
     Resources, Inc. ("Panda"), and Northern relating to the transportation of
     natural gas through a facility located in Dewey County, Oklahoma. The
     Company has assumed the defense of this matter pursuant to the
     indemnification agreement entered into as part of the December 7, 1995,
     settlement among Torch, Panda and the Company discussed above. Northern
     contends that Panda failed to transport the required volumes and that the
     deficiency resulted in a requirement that Panda pay a total of $973,000,
     representing the percentage of the costs of constructing the facilities
     calculated under the contract formula. Northern sued Torch under a written
     guaranty agreement and has claimed, in addition, that Torch denuded the
     assets of Panda and is therefore liable for the debts of Panda. The Company
     maintains that, if litigation is unsuccessful to the Company, Northern
     would only be entitled to the amount of the contractually required volumes.

     On November 17, 1994, Associated Storage Corporation ("Associated") filed a
     lawsuit against the Company alleging that the Company had breached a July
     21, 1993 agreement between Associated and the Company, pursuant to which
     Panda Resources, Inc., and Panda's wholly-owned subsidiary, Richfield
     Natural Gas, Inc. Associated seeks actual damages in the amount of
     $150,000, prejudgment interest, court costs, and attorneys' fees.
     Associated has filed a motion for summary adjuration which was denied by
     the court. The Company has asked Associated to submit to mediation.

11.  LITIGATION, COMMITMENTS AND CONTINGENCIES (continued)

     On October 7, 1994, Northern Natural Gas Company ("Northern") filed a
     lawsuit against the Company alleging that the Company had breached two Firm
     Transportation Service Agreements dated December 1, 1990, between Northern
     and Panda, a former wholly-owned subsidiary of the Company. On June 6,
     1996, Northern and the Company entered into a Settlement Agreement pursuant
     to which (a) the Company issued to Northern 50,000 shares of the Company's
     Series B Senior Convertible Preferred Stock which are convertible (subject
     to adjustment) into 333,333 shares of the Company's common stock, and (b)
     the Company agreed to pay Northern $465,000 in installments of $50,000 by
     June 21, 1996, $150,000 by May 1, 1997, $125,000 by May 1, 1998, and
     $140,000 by May 1, 1999. An agreed judgment was entered in the case, but
     Northern has agreed not to seek to enforce the judgment unless the Company
     defaults in its payment obligations. Once the required payments have been
     made, Northern has agreed to execute a release of the judgment. These
     amounts have been reflected in the Company's consolidated financial
     statements at July 31, 1996.

     Germany Oil Company is a named defendant in three wrongful death actions
     involving an accident which occurred at a heater-treatment unit on the
     Blowhorn Creek Millerella Oil Unit lease in Lamar County, Alabama. Each
     plaintiff seeks damages in the amount of $25 million. The three matters are
     in the initial stages of discovery and have been referred to Germany Oil
     Company's insurance carrier. Germany has an approximate 10% ownership
     interest of the property. Management believes that liability insurance
     coverage is adequate to cover any potential loss.

     Contingencies  - In addition to the foregoing litigation,  the Company is a
     -------------                                                              
     named defendant in lawsuits, is a party in governmental proceedings, and is
     subject to claims of third parties from time to time arising in the
     ordinary course of business. While the outcome of lawsuits or other
     proceedings and claims against the Company cannot be predicted with
     certainty, management does not expect these additional matters to have a
     material adverse effect on the financial position of the Company.

     Commitments
     -----------

     The Company leases office space and certain property and equipment under
     various lease agreements. As of July 31, 1996, future lease commitments
     were approximately as follows:

12.  RELATED PARTY TRANSACTIONS

     In regard to the modification and cancellation of the non-compete
     agreements with the two previous majority shareholders of Panda, Mr.
     Jeffrey T. Wilson assumed the notes receivable due the Company by the two
     former shareholders in the amount of $339,650 plus accrued interest. The
     Board has voted to forgive $380,624, representing the total notes and
     accrued interest, due from Mr. Wilson.

     The Company from time to time, has made loans to certain officers,
     directors and stockholders. The loans are evidenced by demand notes payable
     due on or before December 31, 1996, bearing interest of various rates.

     Estimated Quantities of Proved Oil and Gas Reserves (Unaudited)
     ---------------------------------------------------------------

     The estimates of proved oil and gas reserves utilized in the preparation of
     the consolidated financial statements were prepared by independent
     petroleum engineers at July 31, 1996. Such estimates are in accordance with
     guidelines established by the Securities and Exchange Commission and the
     Financial Accounting Standards Board, which require that reserve reports be
     prepared under existing economic and operating conditions with no provision
     for price and cost escalations except by contractual arrangements. The
     Company's reserves are located onshore in the United States.

     The Company emphasizes that reserve estimates are inherently imprecise.
     Accordingly, the estimates are expected to change as more current
     information becomes available. In addition, a portion of the Company's
     proved reserves are undeveloped, which increases the imprecision inherent
     in estimating reserves which may ultimately be produced.

     Proved reserves are estimated quantities of crude oil, natural gas, and
     natural gas liquids 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 reserves are those which are expected to be recovered through
     existing wells with existing equipment and operating methods. The following
     is an analysis of the Company's proved oil and gas reserves.

     at July 31, 1996.

     Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
     ---------------------------------------------------------------------------
     Oil and Gas Reserves (Unaudited)
     --------------------------------

     The "Standardized Measure of Discounted Future Net Cash Flows Relating to
     Proved Oil and Gas Reserves" (Standardized Measure) is a disclosure
     requirement under SFAS No. 69. The Standardized Measure does not purport to
     present the fair market value of proved oil and gas reserves. This would
     require consideration of expected future economic and operating conditions,
     which are not taken into account in calculating the Standardized Measure.

     Under the Standardized Measure, future cash inflows were estimated by
     applying year-end prices, adjusted for fixed and determinable escalations,
     to the estimated future production of year-end proved reserves. Future cash
     inflows were reduced by the estimated future production and development
     costs based on year-end costs to determine pre-tax cash inflows. Future
     income taxes were computed by applying the statutory tax rate to the excess
     of pre-tax cash inflows over the Company's tax basis in the associated
     proved oil and gas properties. Tax credits and permanent differences were
     also considered in the future income tax calculation. Future net cash
     inflows after income taxes were discounted using a 10% annual discount rate
     to arrive at the Standardized Measure.

     Oil and Gas - The Company is required, by agreement with its primary lender
     -----------
     (Bank of America), to participate in a price protection program, executed
     by Bank of America, for a majority of its gas sales for a 36 month period
     until March 31, 1998. Oil is hedged at a floor of $16.50/Bbl and a ceiling
     of $19.82/Bbl based on projected monthly production. Gas is hedged at
     $1.806/MMBtu based on projected monthly production. The production rates
     were calculated by Bank of America from reserve report data and are fixed
     by Bank of America. The monthly hedge amount is calculated by Bank of
     America from published market rates. The current hedging agreement does not
     allow for full benefit from prices above the ceiling amount.

     The hedging gains or losses for the years ended July 31, 1996 and 1995 are
     as follows:

     primary lender. Interest is hedged to achieve a fixed rate of 7.49% based
     on a fixed amortization schedule determined at loan origination. The
     hedging losses for the year ended July 31, 1996 and 1995 are $504,303 and
     $80,151, respectively, and are included in interest expense for the years

16.  RESTATEMENT OF PRIOR YEAR

     Effective March 31, 1995 the Company acquired Germany Oil Company
     ("Germany") in a purchase transaction. The net assets acquired consisted
     primarily of oil and gas properties. In connection with the transaction the
     Company failed to allocate the purchase price to all assets acquired as
     required by generally accepted accounting principles. During fiscal 1996
     the Company, based on the reports of independent petroleum engineers,
     reallocated the adjusted purchase price as of the date of acquisition.
     Accordingly, the previously reported 1995 amounts have been restated as
     follows:

17.  SUBSEQUENT EVENTS

     Proposed Merger With Alliance Resources Plc - As a result of the demands
     -------------------------------------------
     placed upon the Company by its primary lender, the Company's continuing
     working capital deficit, its deteriorating financial condition and the
     inability of the Company to raise additional debt or equity capital,
     management of the Company, in the forth quarter of fiscal 1996, determined
     to seek an equity infusion through a strategic merger with a suitable
     merger candidate. Management's primary objective in seeking a merger
     partner was to solve the working capital deficit of the Company through an
     equity infusion while minimizing dilution to the shareholders. Although the
     Company considered several potential transactions. Alliance Resources Plc
     ("Alliance") emerged as the candidate most likely to meet the objectives of
     the Company. The Company has entered into an Agreement and Plan of Merger
     ("Alliance Merger Agreement") dated August 12, 1996 with Alliance Resources
     Plc, a company organized under the laws of the United Kingdom ("Alliance"),
     Pursuant to which the Company will merge ("Alliance Merger") with a wholly-
     owned U.S. subsidiary of Alliance.

                         July 31, 1996, 1995, and 1994

17.  SUBSEQUENT EVENTS (continued)

     Under the terms of the Alliance Merger Agreement and after giving effect to
     a 1 for 40 reverse stock split to be completed by Alliance, the holders of
     the Company's common stock will receive 0.8806 ordinary shares of Alliance
     for each share of such common stock, the holders of the Company's Series A
     Convertible Preferred Stock will receive 2.6445 ordinary shares of Alliance
     for each share of such Series A Convertible Preferred Stock, and the
     holders of the Company's Series B Senior Convertible Preferred Stock will
     receive 5.8709 ordinary shares of Alliance for each share of such Series B
     Senior Convertible Preferred Stock. Following the Alliance Merger, the
     holders of the Company's common and preferred stock will own, as a group,
     approximately 72% of the issued and outstanding ordinary shares of Alliance
     and the Company will become a wholly-owned subsidiary of Alliance. Holders
     of outstanding warrants to purchase shares of the Company's common stock
     will receive from Alliance replacement warrants to purchase shares of
     Alliance ordinary shares on substantially the same terms.

     It is anticipated that the merger will provide the Company with sufficient
     capital resources to eliminate its existing working capital deficit,
     refinance the Company's senior debt and eliminate the hedging agreements,
     and provide development capital for exploration of the Company's oil and
     gas properties. In addition, the Company believes that the combination of
     the two companies provides strategic benefits to the Company important to
     its long-term growth and the enhancement of shareholder value. Although
     Alliance's domestic oil and gas operations are significantly smaller than
     the Company's, the Company believes that the merger will enhance the
     overall financial strength of the Company and provide a stable platform
     from which future growth can be achieved. The strategic objectives of the
     combined Company will be to continue a policy of structured and stable
     growth in the domestic U.S. oil and gas sector while implementing projects
     in Western Europe, the Middle East and the former Soviet Union.

     Under the terms of the Alliance Merger Agreement, the Company is required
     to dispose of its interests in its unconsolidated affiliates, Wexford
     Technology, Inc. ("Wexford") and Imperial Petroleum, Inc. ("Imperial"), and
     its interests in its wholly-owned subsidiaries LaTex Resources
     International, Inc. ("LaTex Resources International") and Phoenix Metals,
     Inc. ("Phoenix Metals"). Effective July 31, 1996, the Company has written
     off its $1,811,694 investment in Wexford, its $2,372,452 investment in
     Imperial, and its $955,496 Investment in LaTex Resources International. The
     Company has entered into a Purchase Agreement with Imperial pursuant to
     which the Company will sell its interests in Wexford, Imperial, LaTex
     Resources International and Phoenix Metals to Imperial for 100,000 shares
     of the Company's common stock. Imperial is controlled by the Company's
     President and largest stockholder, Jeffrey T. Wilson. Prior to the
     completion of the sale, the Company intends to obtain an opinion from an
     independent investment banking firm as to the fairness of the transaction
     to the Company's stockholders.

      Effective October 21, 1996, each holder of options granted under the
      Company's 1993 Incentive Stock Plan agreed to terminate all options held
      and receive grants of restricted common stock of the Company. 1,690,000
      options were canceled and 1,690,000 shares of restricted common stock were
      granted. The terms of the Restricted Shares provide that a holder may not
      sell, transfer, or otherwise dispose of any Restricted Shares as long as
      the Company has the right to a forfeiture of the Shares. The terms of the
      Restricted Stock provide that in the event that a holder's employment with
      the Company shall terminate for any reason other than death or total
      disability prior to the earlier of (a) February 1, 1997, or (b) a change
      in control occurs with respect to the Company, the holder shall
      immediately forfeit any right to the shares of Restricted Stock for which
      the restrictions have not otherwise lapsed.

      Disposition of Oil and Gas Properties - Subsequent to year end, the
      -------------------------------------
      Company has entered into letters of intent with two parties to sell oil
      and gas properties for approximately $1,500,000. The Company chose not to
      include those properties in its reserve appraisal at July 31, 1996.

Section 16(a) Reporting Deficiencies

     Section 16(a) of the Securities Exchange Act of 1934 ("Exchange Act")
requires the Company's directors and officers, and persons  who own more than
10% of a registered class of the Company's equity securities, to file initial
reports of ownership on Form 3 and reports of changes in ownership on Forms 4
and 5 with the Securities and Exchange Commission (the "SEC") and the National
Association of Securities Dealers ("NASD").  Such persons  are required by SEC
regulation to furnish the Company with copies of all Section 16(a) forms they
file.

     Based upon a review of Form 3, 4 and 5 filings made by the Company's
officers and directors during the fiscal year ended July 31, 1996 under Section
16(a) of the Exchange Act, the Company believes that: (i) Jeffrey T. Wilson,
Chief Executive Officer, Chairman of the Board, President, and a Director of the

                                       39

     Company on January 31, 1996 and his options lapsed at that time.

Incentive Stock Plan

     The Board of Directors adopted the LaTex Resources, Inc. 1993 Incentive
Stock Plan (the "Plan") effective December 8, 1993 and the Shareholders approved
the Plan at the Company's Annual Meeting on June 2, 1994.  The Plan is
administered by a Compensation Committee consisting of not less than three
members of the Board of Directors and a special committee appointed by the Board
of Directors, as necessary, consisting of not less than three members of the
Board, who are a "disinterested persons" within the meaning of Securities and
Exchange Commission ("SEC") Rule 16b-3, as in effect prior to August 1996, to
address decisions regarding participation by directors and executive officers.

     The aggregate number of shares of the Company's common stock issuable under
the Plan is 2,000,000.  The Plan authorizes the Committee to grant to key
employees options ("Options") to purchase the Company's common stock which may
be in the form of incentive stock options ("ISOs"), or in the form of non-
statutory options ("Non-Statutory Options").  Additionally, the Committee may
grant stock

                                       44
<PAGE>
 
appreciation rights ("SARs") in connection with such Options.  The term of each
Option shall be for such period as the Committee shall determine but no longer
than ten years from the date of grant or five years to an individual who is a
10% shareholder of the Company.  The aggregate fair market value exercisable by
an individual optionee during any calendar year under all stock option plans of
the Company may not exceed $100,000.  The exercise price per share for the
common stock covered by any Options shall be determined by the Committee,
provided that in the case of an ISO, the per share exercise price shall be not
less than the fair market value (or in the case of an ISO granted to an
individual who at the time is a 10% shareholder, 110% of the fair market value)
of one share of common stock.

     The Plan additionally authorizes the Committee to grant restricted common
stock ("Restricted Stock") to key employees.  The Committee may designate a
restriction period with respect to such shares of not less than one year but not
more than five years during which an employee will not be permitted to sell,
transfer, pledge or assign shares of Restricted Stock awarded to him provided,
that within such limitations, the Committee may provide for the lapse of such
restrictions where deemed appropriate.

     Through July 31, 1996, the Company has granted ISOs under the Plan to
Messrs. Wilson, Cox, Henley, Heinsius, and Hull as described in the Summary
Compensation Table and the Option Grants Table above, for a total of 1,450,000
shares (excluding options for 150,000 shares granted to Mr. Shreve which lapsed
upon his resignation as an officer and Director of the Company on January 31,
1996), as well ISOs under the Plan to non-executive officer employees for a
total of 240,000 shares.  By agreement between the holders of all outstanding
ISOs and the Company, effective October 21, 1996 all outstanding ISOs were
terminated.  See "Restricted Stock Grants."

Restricted Stock Grants

     Effective October 21, 1996, each holder of options granted under the
Company's 1993 Incentive Stock Plan agreed to terminate all options held and
received grants of restricted common stock of the Company ("Restricted Stock").
The following table sets forth options cancelled and shares of Restricted Stock
issued with respect to each of the Company's Named Officers and other employees
of the Company as a group.

     The terms of the Restricted Stock provide that a holder may not sell,
transfer, or otherwise dispose of any shares of Restricted Stock as long as the
Company has the right to a forfeiture of the Restricted Stock.  In the event
that a holder's employment with the Company shall terminate for any reason other
than death or total disability prior to the earlier of (a) February 1, 1997, or
(b) a Change in Control occurs with respect to the Company, the holder shall
immediately forfeit any right to the shares of Restricted Stock for which the
restrictions have not otherwise lapsed.  For the purpose of the Restricted
Stock, a "Change in Control" will be deemed to have occurred with respect to the
Company if:  (a) any person becomes the beneficial owner, directly or
indirectly, of securities of the Company representing 50% or more of the
combined voting power of the Company's then outstanding securities; (b)
individuals who constitute the Company's Board of Directors on the date of grant
of the Restricted Stock cease for any

Item 13. Certain Relationships and Related Transactions.

     In connection with the sale by the Company of Panda Resources, Inc. in July

     A portion of the Company's oil and gas production is sold to its wholly-
owned subsidiary, ENPRO, under short-term contracts.  The Company believes that
the terms of such contracts are fair and reasonable.  The Company receives no
less from the sale of production to ENPRO than it would receive from sales to
unrelated third parties.

     Since January 1993 the Company has leased a condominium located in Tulsa,
Oklahoma owned by Jeffrey T. Wilson, Chairman and Chief Executive Officer of the
Company.  Under the terms of the oral lease arrangement, the Company pays Mr.
Wilson approximately $1,100 per month.  The condominium is used by the Company
to house its out of town employees and guests.  At July 31, 1996, the Company
owed Mr. Wilson approximately $8,000 for unpaid rent.

     With respect to transactions between the Company and its affiliates,
Wexford Technology, Inc., and Imperial Petroleum, Inc., see "Item 1. Business
and Item 2. Properties - Other Business."

     In connection with the proposed merger of the Company and Alliance
Resources Plc, the Company has entered into a Purchase Agreement with Imperial
Petroleum, Inc. ("Imperial") dated September 30, 1996 pursuant to which the
Company has agreed to sell to Imperial its interests in Imperial, Wexford
Technology, Inc., LaTex Resources International, Inc. and Phoenix Metals, Inc.
for 100,000 shares of the Company's common stock.  Effective July 31, 1996 the
Company has written off its investments in Imperial, Wexford and LaTex Resources
International in the total amount of $5,139,642.  Effective July 31, 1994 the
Company wrote off its investment in Phoenix Metals in the total amount of

Condition and Results of Operations -- Proposed Merger with Alliance Resources."

     The Company was previously a party to an agreement with Wood Roberts, Inc.
("WRI"), a company controlled by John R. Martinson, a Director of the Company,
pursuant to which WRI acted as a financial advisor to the Company.  Under the
agreement, the Company paid WRI a monthly fee of $4,000 and agreed to pay WRI a
success fee in connection with any merger or acquisition involving a party
introduced to the Company by WRI, and any financing facility arranged by WRI.
WRI assisted the Company in obtaining its credit facility with Bank of America.
Through July 31, 1996, the Company paid WRI cash retainer and success fees of
$55,000.  In addition, the Company has issued to WRI six year common stock
purchase warrants to purchase 536,000 shares at $0.75 per share, of which WRI
has exercised and purchased 100,000 shares.  As of March 4, 1996, the financial
advisor agreement between the Company and WRI was terminated by agreement of the
parties.  By separate agreement the Company agreed to pay Wood Roberts a fee of
$240,000 upon completion of the proposed merger with Alliance Resources Plc and
a fee equal to 0.5% of the amount of any credit facility obtained by the Company
from a bank or other financial institution introduced to the Company by Wood
Roberts in order to refinance its indebtedness to Bank of America.

          consideration of such cancellation, become entitled to receive a new
          warrant issued by Alliance pursuant to which the holder will have the
          right to subscribe for, in accordance with the terms and subject to
          the conditions of the existing Warrant, that number of Alliance Shares

          Warrant,

LaTex Shares (including those who receive LaTex Shares in consideration for the
cancellation of outstanding options to purchase LaTex Shares) shall hold

outstanding (including the 237,500 post-reverse split Alliance Shares issuable
upon exercise of the options approved for management of Alliance) and the
holders of Warrants shall have the right to subscribe an additional 0.8806
Alliance Shares for each LaTex Common Share subject to the Warrants, pursuant to
replacement warrants to be issued by Alliance under the provisions of Section
                                                                      -------

holders thereof, all LaTex Shares and all Warrants shall no longer be
outstanding and shall be canceled and shall cease to exist and each holder of a
certificate representing LaTex Shares or an agreement representing Warrants
shall thereafter cease to have any rights with respect to such LaTex Shares or
such Warrants, and in consideration therefor shall be entitled to receive the
Alliance Shares specified in this Section upon the surrender of the certificate
representing the LaTex Shares as provided in Section 2.7, or the new warrant

certificates, together with such letter of transmittal, duly executed and

cause to be delivered to the persons entitled thereto certificates in respect of
the Alliance Shares and any dividends or distributions thereon to which such
persons are then entitled.

number of Alliance Shares.

          (d) If Alliance Shares are to be issued to a person other than the
registered holder of the certificates surrendered, it shall be a condition of

otherwise in proper form for transfer and that the person requesting such
delivery shall pay any transfer or other taxes required by reason of the
delivery to a person other than the registered holder of the certificates
surrendered or establish to the satisfaction of Alliance or the Paying Agent
that such tax has been paid or is not applicable.

conduct and resolve, in its sole discretion, all negotiations proceedings and
ultimate disposition with respect to any such demands in any manner that the
Surviving Corporation may elect. All such payments shall be made solely by the
Surviving Corporation and shall not be made by, nor shall Alliance reimburse the
Surviving Corporation for, such payments.

absent such imbalance; or (ii) the applicable entity being obligated to make
payment to any person or entity as a result of such imbalance; or (iii)

paid on their behalf) all Taxes due or claimed to be due from them by federal,
state, local or foreign taxing authorities, excluding Taxes that are being

finally settled and no issue has been raised by the Internal Revenue Service in
any such examination that has been resolved adversely to any of the LaTex

Alliance Resources Plc

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


Gentlemen:

      In connection with the pending merger (the "Merger") of LaTex Resources,
Inc., a Delaware corporation (the "Company"), with and into Alliance Resources
(Delaware), Inc., a Delaware corporation ("Acquisition"), a wholly-owned
subsidiary of Alliance Resources Plc, a public limited company incorporated in
England and Wales ("Acquiror"), pursuant to an Agreement and Plan of Merger (the
"Agreement"), I have been advised that I may be deemed to be an "affiliate" of
the Company within the meaning of Rule 145 under the Securities Act of 1933 (the
"1933 Act") for the purposes of any resales of shares of the common stock of
Acquiror to be issued to me (the "Stock"). Based on such advice and in order to
induce Acquiror and the Company to cause the Merger to be consummated, I hereby
represent and warrant to, and agree with, Acquiror, Acquisition, and the Company
as follows:

         A.  I will not sell or otherwise transfer any of the Stock in violation
      of the 1933 Act or the rules or regulations thereunder. I will not, in any
      event, enter into any contract or otherwise agree to, sell or otherwise
      transfer any of the Stock until such time as financial results covering at
      least thirty (30) days of post-Merger combination operations of Acquiror
      and the Company have been published.

         B.  I hereby consent to the placing of a legend on the certificate or
      certificates evidencing the Stock referring to the issuance thereof in a
      transaction to which Rule 145 under the 1933 Act is applicable and to the
      giving of stop transfer instructions to the transfer agent for the Stock
      with respect to such certificate or certificates. The legend will state in
      substance:

         "The shares represented by this certificate were issued in a
         transaction to which Rule 145 under the Securities Act of 1933      

                                      60
<PAGE>
 
         applies and may be sold or otherwise transferred only in compliance
         with the terms of an agreement of affiliate dated ____________, 199__
         between the registered holder hereof and the issuer hereof, a copy of
         which is available at the principal office of the issuer."

     C.  In the event of any sale or transfer of any of the Stock in a
transaction not involving a sale pursuant to Rule 145 or in a registered public
offering, I will obtain from each transferee of the Stock in such transaction a
letter agreement substantially similar hereto, or a letter containing such other
information reasonable required by Acquiror to evidence an exception from the
applicable registration requirements of federal or State securities laws, which
is binding and enforceable by Acquiror and the transferee.

                                             Very truly yours,

connection with the transactions contemplated hereby.

         3.09 Investment Intent.

              (a) Imperial understands and acknowledges the speculative
nature of and substantial risk of loss associated with an investment in the Sold
Shares which may be subject to substantial dilution. Imperial represents and
warrants that the Sold Shares constitute an investment which is suitable and
consistent with its financial condition and that it is able to bear the risks of
such investment for an indefinite period of time, which may include the total
loss of its investment in the Sold Shares. Imperial further represents that
Imperial has adequate means of providing for its current financial needs and
contingencies and no need for liquidity in its investment in the Sold Shares and
that Imperial has sufficient financial and business experience to evaluate the
merits and risks of an investment in the Sold Shares.

              (b) Imperial understands and acknowledges that the Sold Shares
have not been, and will not be, registered under the Securities Act or
applicable securities laws of any state and Imperial is aware that no federal or
state agency has made any review, finding or determination regarding the terms
of the acquisition of the Sold Shares nor any 

                                       10
<PAGE>
 
recommendation or endorsement of the Sold Shares as an investment, and Imperial
must forego the security, if any, that such a review would provide.

              (c) Imperial understands and acknowledges that the Sold Shares
are being offered and sold to Imperial under exemptions from registration
provided by the Securities Act and exemptions provided by applicable state
securities laws and Imperial warrants and represents that the Sold Shares are
being acquired by it solely for its own account, for investment purposes only,
and not with a view to or for the resale, distribution, subdivision or
fractionalization thereof. Imperial represents and warrants that it has no
agreement or other arrangement, formal or informal, with any person to sell,
transfer or pledge any part of the Sold Shares or which would guarantee it any
profit or protect it against any loss with respect to the Sold Shares. Further,
Imperial has no plans to enter into any such agreement or arrangement, and,
consequently, it must bear the economic risk of an investment in the Sold Shares
for an indefinite period of time.

         3.10 Limitations on Resale or Transfer. Imperial understands and
              ---------------------------------
acknowledges that the Sold Shares will be "restricted' as defined in Rule 144
under the Securities Act and that it cannot offer to sell, sell or otherwise
transfer or distribute the Sold Shares without registration thereof under both
the Securities Act and any applicable state securities laws, or unless an
exemption is, in the opinion of counsel, available to it under the Securities
Act. Imperial further understands and acknowledges that the restrictions on the
transfer of the Sold Shares will be noted on the books of each Sold Company,
respectively, and that the stock certificates representing the Sold Shares will
bear a written legend setting forth the restriction on the transferability of
the Sold Shares in substantially the following form:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933. THE SECURITIES HAVE BEEN ACQUIRED FOR
         INVESTMENT AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN
         EFFECTIVE REGISTRATION OF THEM UNDER THE SECURITIES ACT OF 1933, OR AN
         OPINION OF COUNSEL SATISFACTORY TO THE ISSUER THAT SUCH REGISTRATION IS
         NOT REQUIRED UNDER THE ACT.

              --------------------------------------
has received, reviewed, understands and has fully considered (including, without
limitation, the financial statements contained therein) for purposes of its
acquisition of the Sold Shares, the LRI Disclosure Reports. Imperial represents
and warrants that in making the decision to acquire the Sold Shares, it has
relied upon its own independent investigation of the Sold Companies and the
independent investigation by its representatives, including its own professional
legal, tax, and business advisors, and that it and its representatives have been
given the opportunity to examine all relevant documents and to ask questions of
and to receive answers from LRI, or person(s) acting on its behalf, concerning
the terms and conditions of acquisition by Imperial of the Sold Shares and any
other matters concerning an investment in the Sold

the Third Party Claim, only insofar as such knowing failure to notify the
Indemnitor actually resulted in prejudice or damage to the Indemnitor.

         7.05 Right to Contest and Defend. The Indemnitor is entitled at its
              ---------------------------
cost and expense to contest and defend by all appropriate legal proceedings any
Third Party Claim with respect to which it is called upon to indemnify an
Indemnitee under the provisions of this Agreement; provided, that notice of the
intention to so contest shall be delivered by the Indemnitor to the Indemnitee
within 20 calendar days from the date of receipt by the Indemnitor of notice by
the Indemnitee of the assertion of the Third Party Claim. Any such contest may
be conducted in the name and on behalf of the Indemnitor or the Indemnitee as
may be appropriate. Such contest shall be conducted by reputable counsel
employed by the Indemnitor, but the Indemnitee shall have the right to
participate in such proceedings and to be represented by counsel of its own
choosing at its sole cost and expense. If the Indemnitee joins in any such
contest, the Indemnitor shall have full authority to determine all action to be
taken with respect thereto; provided, however, that the Indemnitor will not have
the authority to subject the Indemnitee to any obligation whatsoever, other than
the performance of purely ministerial tasks (e.g., the execution of settlement
agreements and other documentation) or obligations not involving material
expense. If the Indemnitor does not elect to contest any such claim, any
Indemnitor shall be bound by the result obtained with respect thereto by the
Indemnitee. At any time after the commencement of the defense of any Third Party
Claim, the Indemnitor may request the Indemnitee to agree in writing to the
abandonment of such contest or to the payment or compromise by the Indemnitor of
the asserted Third Party Claim, whereupon such action shall be taken unless the
Indemnitee determines that the contest should be continued, and so notifies the
Indemnitor in writing within 15 days of such request from the Indemnitor. If the
Indemnitee determines that the contest should be continued, the Indemnitor shall
be liable hereunder only to the extent of the amount that the other party to the
contested Third Party Claim had agreed unconditionally to accept in payment or
compromise as of the time the Indemnitor made its request therefor to the
Indemnitee.

         7.06 Cooperation. If requested by the Indemnitor, the Indemnitee agrees
              -----------
to cooperate with the Indemnitor and its counsel in contesting any Third Party
Claim that the Indemnitor elects to contest or, if appropriate, in making any
counterclaim against the person asserting the Third Party Claim, or any
cross-complaint against any person, but the Indemnitor will reimburse the
Indemnitee for any expenses incurred by it in so cooperating.

         7.07 Right to Participate. The Indemnitor agrees to afford the
              --------------------
Indemnitee and its counsel the opportunity to be present at, and to participate
in, conferences with all persons, including governmental authorities, asserting
any Third Party Claim against the Indemnitee or conferences with representatives
of or counsel for such persons.

         7.08 Payment of Damages. The Indemnitor shall pay to the Indemnitee in
              ------------------
immediately available funds the amount of any damages to which the Indemnitee
may become entitled by reason of the provisions of this Article 7, such payment
                                                        ---------
to be made within 10 calendar days after any such amount of damages is finally
determined either by mutual agreement of the parties hereto or the final
unappealable judgment of a court of competent jurisdiction.

         7.09 No Insurance: Subrogation. The indemnifications provided in this
              -------------------------
Article 7 shall not be construed as a form of insurance and shall be binding
- ---------
upon and inure to the benefit of Imperial, LRI and its respective Affiliates,
heirs, successors and permitted assigns. To the extent permitted under existing
insurance contracts and applicable laws, Imperial and LRI hereby waive for
themselves, its Affiliates, heirs, successors and permitted assigns, including
without limitation any insurers, any rights to subrogation for Losses arising
from Third Party Claims for which each of them is respectively liable or against
which each respectively indemnifies the other, and, if necessary, said parties
shall obtain waiver of such subrogation from its respective insurers.

                                8. Miscellaneous
                                   -------------

           8.01 Press Releases and Public Announcements. No party shall issue
                ---------------------------------------

brokerage or finder's fees or agent's commissions or other like payment has been
agreed to be paid by him or it in connection with this Agreement or on account
of the transactions contemplated by this Agreement. Each party agrees to
indemnify and hold harmless the other parties from and against any and every
claim arising by breach of the aforesaid representation and warranty and all
costs and expenses, legal or otherwise, which any such party may incur as the
result of any such claim.

           8.03 Survival of Representations. All representations, warranties and
                ---------------------------
agreements contained herein or made in writing by the parties in connection with
the transaction contemplated hereby, except any representation, warranty or

Attention:         Mr. Jeffrey T. Wilson, Chairman and CEO
- ---------
Gentlemen:

Rauscher Pierce & Clark, Inc. and Rauscher Pierce & Clark Limited (hereinafter
collectively "RP&C") are pleased and honoured to have been selected to represent
LaTex Resources, Inc. (the "Company") as the Company's financial advisor on the
terms set forth below:

l.         The Company hereby appoints RP&C and RP&C agrees to serve as the
           Company's financial advisor from 1 December 1995 until 1 June 1997.
           The scope of RP&C's services will include advising the Company on
           manners relating to:

           a.         The development of a corporate financing strategy;

           b.         Identifying potential sources of capital and discussing
                      the Company and its activities and prospects with 
                      European-based institutional and private investors with a
                      view to recommending to the Company a private placement
                      ("Placement") of either debt or equity securities
                      (hereinafter "Securities"). In the event such placement of
                      Securities is agreed by the Company, and the parties
                      execute a formal engagement agreement, RP&C's duties shall
                      include advising on the structuring of the offering and
                      terms of the Securities, assisting to prepare
                      documentation and marketing the proposed offering to
                      investors in Europe.

            c.        The identification of potential merger and/or acquisition
                      candidates ("Candidate ) and representing the Company in
                      discussions and negotiations with candidates

Reference 4.29 (ix)  Contacts: Brokerage or Finder's Agreements  Page 7 of 10
<PAGE>
 
2.         Other than through RP&C, during the term of this Agreement the
           Company will not, directly or indirectly sell or offer, or attempt to
           offer to dispose of; or solicit any offer to buy, or otherwise
           approach or negotiate in respect of the sale of the Company's
           Securities. In addition the Company will not enter into negotiations
           or execute any letters of intent or commitment letters relating to
           potential business combination transactions, other than through RP&C.

3.         The Company shall be responsible for the contents of any disclosure
           documents used by RP&C in connection with its services hereunder, and
           you represent that such documents will contain any untrue statements
           of a material fact or omit to state a material fact necessary in
           order to make the statements made, in light of the circumstances in
           which they were made, not misleading. In rendering our services, we
           will use only such information and documents as are provided by you
           or prepared by us with your approval, and we will not make any
           unauthorized or untrue statements of a material fact or omit to state
           a material fact that is necessary in order to make the statements
           made by us, in light of the circumstances in which they were made,
           not misleading.
                  
4.         The Company will reimburse RP&C monthly for all reasonable
           out-of-pocket expenses (including travel, entertainment, legal fees
           and expenses) incurred in connection with RP&C's services hereunder.

5.         During the term of this Agreement, the Company shall pay RP&C a non-
           refundable monthly retainer of $5,000 commencing December 1, 1995.

6.         In the event that the Company agrees to go forward with a Placement,
           the Company and RP&C shall enter into an engagement letter with
           respect to such Placement, which letter will provide, inter alia,
           that the Company shall:

           (a)        Pay RP&C a Placement Agent fee ("Placement Fee") equal to
                      between 8% and 10% (depending on the size of the offering)
                      of the aggregate gross proceeds from the Placement.

           (b)        Sell for a price of $100 to RP&C, concurrently with the
                      successful completion and closing of the Placement,
                      warrants to purchase the number of shares of Company's
                      common stock equal to 10% of the amount closed in the
                      Placement and exercisable at the same price per share as
                      paid by investors in the Placement.

7.         In the event that the Company commences discussions with a potential
           Candidate, RP&C's services would include assisting the Company in the
           negotiation of the financial aspects of the proposed transaction. For
           RP&C's services, it is agreed that the Company shall pay RP&C a fee
           equal to 2% of the aggregate consideration received by the Candidate
           and/or Company. Such fee shall be contingent upon the consummation of
           a transaction and, except as otherwise provided below, be payable to
           us in cash. 

Reference 4.29 (ix)  Contacts: Brokerage or Finder's Agreements  Page 8 of 10 
<PAGE>
 
           In the case of an acquisition, the aggregate consideration shall be
           deemed to be the total amount received or paid upon consummation of
           the acquisition (including any debt or capital lease obligations
           assumed, extinguished or discharged), plus, in the case of an
           acquisition of assets, the net value of any current assets not sold.
           If the consideration per share to be received by the holders of the
           common stock exceeds the conversion price of any of the outstanding
           convertible securities (excluding stock options), such securities
           shall be considered to have been converted for purposes of
           calculating the amount of aggregate consideration. If such aggregate
           consideration may be increased by contingent payments related to
           future earnings or operations, the portion of our fee relating
           thereto shall be calculated and paid when and as such contingent
           payments are made.

           In the event that the consideration is paid in whole or in part in
           the form of securities of the Company or the Candidate, the value of
           such securities, for purposes of calculating our fee, shall be the
           fair market value thereof, as the parties hereto shall mutually
           agree, on the day prior to the closing of the sale; provided,
           however, that if such securities consist of stock with an existing
           public trading market, the value thereof shall be determined by the
           last sales price for such stock on the last trading day thereof prior
           to such closing.

           The Company also agrees to reimburse RP&C for all out-of-pocket
           expenses incurred on this project. Such expense reimbursement is not
           contingent upon the successful completion of the transaction
           contemplated hereunder, and shall be payable as billed by RP&C from
           time to time.

8.         In the event that any action, proceeding or investigation is brought
           or asserted against RP&C in connection with any matter referred to in
           this Agreement, the Company will reimburse RP&C periodically for its
           reasonable legal and other expenses (including the cost of any
           investigation and preparation) incurred in connection therewith,
           except to the extent that such action, proceeding or investigation
           results from RP&C's own gross negligence, bad faith, or RP&C's breach
           of this Agreement in performing the services which are the subject of
           this letter. The Company also will indemnify RP&C against any losses,
           claims, damages or liabilities incurred by RP&C arriving out of a
           claim brought in connection with any matter referred to in this
           letter, except to the extent that any such loss, claim, damage or
           liability results from RP&C's gross negligence.

           The Company's reimbursement, indemnity and contribution obligations
           under this paragraph shall extend upon the same terms and conditions
           to RP&C's directors, shareholders, officers and employees, and shall
           be binding upon and inure to the benefit of any of the Company's
           successors and assigns; The foregoing provisions shall survive the
           period of RP&C's services under this letter.

9.         The Company understands that RP&C's engagement may involve work in
           the UK which will or may be described as "investment business" for
           the purposes of the UK Financial Services Act 1986 ("FSA"). This work
           will be undertaken by Rauscher Pierce & Clark Limited ("RPCL"), which

           Company's experience and understanding in relation to investments, we
           have categorized the Company as a non-private customer. As a
           consequence of this categorization, the Company will lose the
           protections afforded to private customers under the SFA Rules. Please
           note that the Company's rights to sue RPCL for damages under Section
           62 of the FSA will be restricted as you will only be able to sue for
           breaches of specific obligations owed to the Company. You will also
           lose the right of access to the Consumer Arbitration Scheme of the
           SFA.

10.        The Company understands that RP&C will be acting as the Company's
           financial advisor and that no understanding, expressed or implied,
           has been made by RP&C that a Placement can be made.

11.        RP&C shall be entitled to full compensation from the Company for any
           party with which discussions looking to a sale of the Company's
           Securities have been held during the period, including any agreed
           extensions, in the event that at any time prior to the expiration of
           one year after termination of this Agreement a sale of the Company's
           Securities is consummated with such party.

Kindly confirm the Company's acceptance and agreement to the foregoing terms by
signing and returning one of the enclosed duplicates of this letter which will
thereupon constitute an agreement between us. Thank you again for the

                         2.  Disposition of Litigation
                         -----------------------------


2.1  Nuevo agrees to dismiss with prejudice all of its claims against LaTex
     Resources and LaTex Petroleum in the Nuevo case, with each side bearing its
     attorneys' fees, expenses, and court costs. The attorneys for Nuevo, LaTex

     transportation agreements at issue upon request by LaTex Resources and will
     use best efforts to provide witnesses for deposition and trial (at the
     expense of LaTex Resources, if travel is necessary) who are under their
     control.
<PAGE>
 
2.5  The obligations of LaTex Resources referenced in paragraphs 1.4, 1.5, 1.6,

     favor of TEMI and against LaTex Resources in the amount of $1 million, less
     any payments that LaTex Resources has previously made to TEMI pursuant to
     said paragraphs. The agreed judgment will be signed by the attorneys for
     TEMI and LaTex Resources, and it will be submitted to the Judge presiding
     in the TEMI case for signature. However, the agreed judgment will not be
     abstracted, executed upon, or otherwise enforced, unless and until LaTex
     Resources defaults in any of its obligations referenced in paragraphs 1.4,
     1.5, 1.6, and 1.7. In the event LaTex Resources timely and properly
     satisfies its obligations under said paragraphs, a release of the agreed
     judgment will be executed by the parties and filed with the Court. In order
     to accomplish the foregoing, TEMI and LaTex Resources will direct their
     attorneys to execute and enter with the Court the form of agreed judgment
     attached hereto as Exhibit "E", seeking enforcement of said agreed judgment
     only in the judgement of the described defaults, and to execute the form of
     release of judgment attached hereto as Exhibit "F", which will be filed
     upon timely and proper satisfaction of the described obligations.

                              3.  Mutual Releases

       TO THE HONORABLE JUDGE OF SAID COURT:

             COMES NOW, LaTex Resources, Inc., Defendant ("LaTex"), and files
        its Withdrawal of Motion for Leave to File Third Party Action, and in
        support thereof would show the Court as follows:

       1.    LaTex and Panda Resources, Inc. ("Panda") have settled the issues
       between them that related to this lawsuit. Part of the settlement
       requires that LaTex withdraw its previously filed Motion for Leave to
       File Third Party Action. That Motion sought to make Panda, as proposed
       third-party defendant, liable to LaTex or to Northern Natural Gas
       Company, Plaintiff ("Northern"), for all or part of Northern's claims
       against LaTex.

       2.    LaTex intends that this withdrawal shall operate as a prohibition
       against all future attempts by LaTex to make Panda a party to this
       lawsuit.

             WHEREFORE, PREMISES CONSIDERED, LaTex Resources, Inc., Defendant,
        requests the Court to order:

             1.   the withdrawal of LaTex's Motion for Leave to File Third Party
                  Action;

             2.   that this withdrawal be made with prejudice, prohibiting LaTex
                  from ever again seeking to make Panda a party to this lawsuit;
                  and

             3.   that attorney's fees, expenses, and court costs are to be
                  borne by the party incurring same.

standing under the laws of the state of Delaware. Northern has the corporate
right, power and authority: (i) to conduct its business and own its properties
and (ii) to execute and deliver this Settlement Agreement and perform all of its
obligations under the same.

behalf of Northern and this Settlement Agreement constitutes the legal, valid
and binding obligation of Northern enforceable against it in accordance with its
terms, subject, however, to bankruptcy, insolvency, fraudulent transfer,
reorganization and other laws affecting creditors' rights generally and with

proceedings to obtain such remedies may be pending.



                                       5
<PAGE>
 
     (3) The making and performance by Northern of this Settlement Agreement is
within its corporate powers, has been duly authorized by all necessary corporate
action on the part of Northern and does not and will not (i) violate in any
material respect any provision of law or any rule, regulation, order, writ,
judgment, decree, or determination currently in effect having applicability to
Northern or Northern's certificate of incorporation, by laws, or other governing
documents, (ii) result in a material breach of or constitute a material default
under any indenture, bank loan, or credit agreement or any other material

agreement, or instrument in any way that now or in the future will materially
adversely affect the ability of Northern to perform its obligations under this
Settlement Agreement.

     (4)  With respect to Northern's acquisition of the Series  B Preferred
          Stock, Northern represents and warrants to LaTex as follows:

     (i)  Northern is an accredited Investor as defined in Section 2(15) of the
          Securities Act of 1933 ("1933 Act") and Rule 501(a)(3) promulgated by
          the Securities and Exchange Commission ("SEC") in that Northern is a
          corporation not formed for the specific purpose of acquiring the
          Series B Preferred Stock and Northern has total assets in excess of
          $5,000,000.

     (ii) Northern acknowledges that neither the Series B Preferred Stock nor
          the Common Shares issuable to Northern upon conversion of the Series B
          Preferred Stock have been registered under the 1993 Act, the Oklahoma
          Securities Act, as amended, or the securities laws of any other state
          and are



                                       6
<PAGE>
 
          being offered, and will be sold, pursuant to applicable exemptions
          from such registration and will be issued as "restricted securities"
          as defined by Rule 144 promulgated pursuant to the 1933 Act. The
          Series B Preferred Stock and the Common Shares may not be resold in
          the absence of an effective registration thereof under the 1933 Act
          and applicable state securities laws unless applicable exemptions from
          registration are available.

 (iii)    Northern is acquiring the Series B Preferred Stock in connection with
          the settlement of the Litigation, and may assign the Series B
          Preferred Stock to an affiliate. Neither Northern nor its affiliate is
          acquiring the Series B Preferred Stock with a view to or for sale in
          connection with any distribution (within the meaning of the 1933 Act)
          or in a manner which would require registration under the 1933 Act or
          any state securities laws, and neither Northern nor its affiliate has
          any present intention or plan to effect any such distribution of the
          Series B Preferred Stock, except pursuant to effective registration in
          compliance with applicable securities laws or pursuant to applicable
          exemptions from such registration.

 (iv)     Northern understands and acknowledges that the certificates evidencing
          the Series B Preferred Stock and the Common Shares issued upon
          conversion of the Series B Preferred Stock shall bear the following
          restrictive legend:



                                       7
<PAGE>
 
                  THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                  THE SECURITIES LAWS OF ANY STATE. THE SECURITIES HAVE BEEN
                  ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD OR TRANSFERRED FOR
                  VALUE IN THE ABSENCE OF AN EFFECTIVE REGISTRATION THEREOF
                  UNDER THE SECURITIES ACT OF 1933 AND/OR THE SECURITIES ACT OF
                  ANY STATE HAVING JURISDICTION UNLESS APPLICABLE EXEMPTIONS
                  FROM REGISTRATION ARE AVAILABLE.

         or such other restrictive legend as counsel to LaTex may reasonably
         deem appropriate at the time of such issuance.

   (v)   Northern understands and acknowledges the speculative nature of and
         substantial risk of loss associated with an investment in the Series B
         Preferred Stock. Northern represents and warrants that the Series B
         Preferred Stock constitute an investment which is suitable and
         consistent with Northern's financial condition and that Northern is
         able to bear the risks of such an investment for an indefinite period
         of time, which may include the total loss of Northern's investment.
         Northern further represents that it has adequate means of providing for
         Northern's current financial needs and contingencies and that there is
         no need for liquidity in Northern's investment in the Series B
         Preferred Stock and that Northern has sufficient



                                       8
<PAGE>
 
         financial and business experience to evaluate the merits and risks of
         an investment in the Series B Preferred Stock.

  (vi)   Northern confirms that (a) Northern has received, reviewed, and has
         fully considered (including, without limitation, the financial
         statements contained therein) for purposes of Northern's acquisition of
         the Series B Preferred Stock, LaTex's Annual Report on Form 10-K for
         the fiscal year ended July 31, 1995, as filed with the SEC, and
         Quarterly Report on Form 10-Q for the three months ended January 31,
         1996, as filed with the SEC, and that (b) Northern has been expressly
         offered the opportunity to be provided a copy of and to review all
         reports, documents, and exhibits referenced therein. Northern
         acknowledges that (a) LaTex has limited financial resources and will
         need additional sources of capital to implement its current business
         plan, the availability of which is uncertain and cannot be assured, and
         (b) the Series B Preferred Stock are a highly speculative investment
         with a high degree of risk of loss by Northern of its investment
         therein. Northern represents and warrants that in making the decision
         to acquire the Series B Preferred Stock, it has relied upon its own
         independent investigation of LaTex and the independent investigations
         of LaTex by Northern's representatives, including its own




                                       9
<PAGE>
 
         professional legal, tax, and business advisors, and that Northern and
         its representatives have been given the opportunity to examine all
         relevant documents and to ask questions and to receive answers from
         LaTex, or person(s) acting on its behalf, concerning LaTex and its
         operations and financial condition, the terms and conditions of
         acquisition by Northern of the Series B Preferred Stock, and any other
         matters concerning an investment in LaTex, and to obtain any additional
         information Northern deems necessary or appropriate to verify the
         accuracy of the information provided.

     D.  Payment.
         -------

         In further consideration of the compromise and settlement of the

year. Dividends shall be payable in cash in quarterly installments on each
Dividend Payment Date in the amount accrued to such Dividend Payment Date;
provided, however, that cash dividends shall be required to be paid only to the
extent the Company may lawfully do so under the Delaware Act; and, provided
further, that notwithstanding any other provision of this Certificate of
Designation, if the Company may not lawfully under the Delaware Act pay all the
dividends it is required to pay under this Section 3 on any Dividend Payment
                                           ---------
Date, it shall pay on such date all the dividends it may lawfully pay pro rata

it shall do so; and, provided further, notwithstanding any other provision of
this Certificate of Designation, until such time as the Company's indebtedness

or refinanced by a third party, the Company shall be permitted, in lieu of the
cash dividend payments required above, to satisfy its obligation to make

shares of Preferred Stock issuable to a particular holder pursuant to the last
proviso of the preceding sentence and (ii) minimizing fractional shares, all

Preferred Stock shall be aggregated prior to dividing by $10.00. Any remaining
fractional share after the foregoing computation shall be rounded up if the
fraction is one-half or more, and rounded down if the fraction



                                      -4-
<PAGE>
 
is less than one-half. For example, if by reason of the application of the
proviso above referring to Bank of America indebtedness the Company is only
permitted to pay dividends in additional shares of Preferred Stock, the
following stock dividends would be payable; (x) a holder of 10,000 shares of
Preferred Stock would be entitled to $.30 (the quarterly dividend amount) x
10,000 = $3000/$10 = 300 shares of Preferred Stock and (y) a holder of 10,550
shares of Preferred Stock would be entitled to $.30 (the quarterly dividend
amount) x 10,550 = $3165/$10 = 316.5 shares or 317 shares of Preferred Stock
after rounding up. Dividends on each share of the Preferred Stock shall commence
to accrue and shall be cumulative from (i) April 1, 1995, in the case of the
initial 370,000 shares of Preferred Stock issued; and (ii) in the case of all
shares of Preferred Stock issued as dividends pursuant to Section 3.1, the
Dividend Payment Date with respect to which such shares were issued. Dividends
shall accrue and be cumulative as provided in the preceding sentence whether or
nor they are earned, declared, or lawfully payable under the Delaware Act If any
dividend which is required to be paid on any Dividend Payment Date is not paid
for any reason, such unpaid dividend shall thereafter bear interest at the
higher of (i) eighteen percent (18%) per annum, or (ii) the prime rate charged
by First Interstate Bank of Texas, N.A. to its commercial customers, plus three
percentage points per annum; provided, in no event shall the foregoing interest
rate exceed the maximum nonusurious rate of interest permitted by applicable
law.  In the event the Company fails to make any dividend required to be made
pursuant to the preceding provisions for two consecutive Dividend Payment Dates,
the holders of Preferred Stock. voting as a class, shall immediately be entitled
at its option to appoint a person or persons comprising not more than 22% of the
Company's Board of Directors to serve thereon until all unpaid dividends have
been made current; provided, under the circumstances described, the holders of
Preferred Stock shall be entitled to appoint at least one director to the
Company's Board of Directors.

          3.2 Priority. The Company shall make no distribution to the holders of
              --------
Junior Stock in any fiscal year except as permitted in this Section 3.2 and
                                                            -----------

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

(common or preferred) of the Company), or the purchase or redemption of shares
of the Company for cash or property, but does not include repurchase of shares
from a terminated employee or consultant of the Company within the terms of an
agreement applicable to such an employee providing for such repurchase. The
Company shall make no distributions to the holders of Junior Stock at any time
that any share of Preferred Stock remains outstanding except in accordance with
Section 9 below.

          3.3  Conversion.  Upon conversion of a share of Preferred Stock into
               ----------
Common Stock, all accumulated dividends on each share of Preferred Stock so
converted shall be payable by the Company to the holder of such share in cash;
provided, that to the extent such dividend cannot be legally declared and paid
or to the extent the holder elects at the time of such conversion, the holder
shall be entitled to receive additional shares of Common Stock on conversion
equal to the number of shares that the unpaid dividends on converted shares of
Preferred Stock would purchase at the Market Price on the date of conversion.

          (a) Any redemption effected pursuant to Section 4.1 shall be made on a
                                                  -----------
     pro rata basis among the holders of the Preferred Stock in proportion to
     the shares of Preferred Stock then held by them.

          (b)   No such optional redemption may be made unless all accumulated
     dividends (including any interest thereon or other charges related thereto)
     on all outstanding shares of Preferred Stock have been paid to the date of
     such optional redemption and adequate provision has been made for the
     payment of all dividends on the Preferred Stock due for the then current
     Dividend Period.

          (c)   The optional redemption shall be effected by call and written or
     printed notice by certified mail, postage prepaid, return receipt
     requested, to the holders of record of the Preferred Stock being redeemed,
     such notice to be addressed to each holder at the address shown in the
     Company's records which notice shall (i) specify the date of redemption,
     (ii) the number of shares of the holder to be redeemed (iii) the Redemption
     Price, (iv) the place at which holders of the Preferred Stock may obtain
     payment of the Redemption Price, (v) the date on which conversion rights
     with respect to the Preferred Stock terminate and (vi) such other
     information, if any, as the Company's Board of Directors may deem
     appropriate. Such notice shall be given no more than 60 but no less than 30
     days prior to the date fixed for redemption.  On or after the date of
     redemption as specified in such notice, each holder shall surrender to the
     Company, at the place specified in such notice, his certificate or
     certificates (or comply with applicable lost certificate provisions) for
     the Preferred Stock to be redeemed as stated in the notice (except that
     such number of shares shall be reduced by the number of shares which have
     been converted pursuant to Section 7 hereof between the date of notice and
                                ---------
     the date on which conversion rights terminate). Provided such notice is
     duly given and provided that on the redemption date specified there shall
     be a source of funds legally available for such redemption and the
     Redemption Price necessary for the redemption shall have been paid, then
     all rights with respect to such shares shall, after the specified
     redemption date, terminate, whether or not said certificates have been
     surrendered, excepting only in the latter instance the rights of the holder
     to receive the Redemption Price thereof, without interest, upon such
     surrender (or compliance with lost certificate provisions).

          4.3  No Reissue of Shares. Any shares of the Preferred Stock redeemed,
               --------------------
purchased, or otherwise acquired by the Company shall be deemed retired and
shall be canceled and may not under any circumstances thereafter be issued or
otherwise disposed of by the company.

          4.4  Conversion. In the event the Company shall give notice of an
               ----------
optional redemption of Preferred Stock as provided in Section 4.2 above, then
                                                      -----------
each holder of Preferred Stock may thereafter elect, in accordance with 
Section 7 below, to convert all or any portion of such holder's Preferred Stock
- ---------
to Common Stock at any time on or before the last business day preceding the
date fixed for redemption.

     5.  Voting Rights. Except as otherwise required by law or as provided in
         -------------
this Certificate of Designation, the holders of the Preferred Stock shall not be
entitled to notice of any meeting of the holders of the Company's voting
securities and the shares of Preferred Stock shall not have any voting rights.

      6.  Liquidation Preference.
          ----------------------

          6.1  General.
               -------

          (a)   Subject to the remaining provisions of this Section 6, in the
                                                            ---------
     event of any liquidation, dissolution, or winding up of the affairs of the
     Company, whether voluntary or involuntary, after payment or provision for
     payment of the debts and liabilities of the Company, the holders of the
     Preferred Stock shall be entitled to receive, out of the remaining assets
     of the Company, the Liquidation Value in cash for each of the shares of
     Preferred Stock they then hold, plus an amount equal to all dividends
     accumulated and unpaid on each such share (including any interest thereon
     or other charges related thereto) through the date fixed for distribution,
     before any distribution shall be made to the holders of any shares of
     Junior Stock. If upon any liquidation, dissolution or winding up of the
     affairs of the Company, whether voluntary or involuntary, the assets of the
     Company available for distribution to shareholders shall be insufficient to
     permit the payment to the holders of the Preferred Stock of the aforesaid
     preferential amounts, then the entire assets of the Company shall be
     distributed ratably among the holders of the Preferred Stock then
     outstanding according to the number of shares held by each.

          (b)   After payment to the holders of the Preferred Stock of the
     amounts set forth in Section 6.1(a) above, the entire remaining assets and
                          --------------
     funds of the Company legally available for distribution, if any, shall be
     distributed among the holders of the Common Stock and the Preferred Stock
     in proportion to the shares of Common Stock then held by them and the
     shares of Common Stock which they then have the right to acquire upon
     conversion of the shares of Preferred Stock then held by them.

          6.2  Merger or Consolidation. For purposes of this Section 6, a
               -----------------------                       ---------
liquidation, dissolution, or winding up of the Company shall be deemed to be
occasioned by, and



                                      -7-
<PAGE>
 
include, the Company's sale of all or substantially all of its assets or the
merger or consolidation for the Company into or with any other Person if the
holders of the outstanding voting shares of the Company prior to such merger or
consolidation do not retain a majority of the voting power of the surviving
Person.  For such purposes, the exchange of securities of the surviving Person
for securities of the Company shall be deemed to constitute a merger or
consolidation of the Company.

          6.3  Fair Value. The fair value of the assets or property to be
               ----------
distributed or exchanged to or with the holders of the Preferred Stock in the
event of a liquidation, dissolution or winding up of the Company pursuant to
Section 6.1 shall be determined by the Board of Directors of the Company in good
- -----------
faith, provided that any securities to be delivered to the holders of Preferred
Stock or Common Stock under this Section 6 shall be valued at Market Price.
                                 ---------

          6.4  No Restriction on Surplus. No provision of this Section 6 shall
               -------------------------                       ---------
in any manner, prior to any liquidation, dissolution, or winding up of the
affairs of the Company, whether voluntary or otherwise, create or be deemed to
create any restrictions upon the surplus of the Company or prohibit the payment
of dividends on the capital stock of the Company out of the funds of the Company
legally available therefor, nor shall any such restrictions or prohibition be in
any manner inferred from the provisions of this Section 6.
                                                ---------

     7.  Conversion.
         ----------

          7.1  Voluntary Conversion. Any holder of Preferred Stock may at any
               --------------------
time and from time to time convert all or any portion of the Preferred Stock
held thereby (and any fractional share thereof) into a number of fully paid and
nonassessable shares of Common Stock of Issuer determined by multiplying the
number of shares of Preferred Stock to be converted by $10.00 and dividing the
result by the Conversion Price (as defined in Section 7.3) then in effect.
                                              -----------

          7.2  Conversion Procedure.
               --------------------

               (a) Each conversion of Preferred Stock will be deemed to have
     been effected as of the close of business on the date on which the
     certificate or certificates representing the Preferred Stock to be
     converted have been surrendered at the principal office of Issuer. At such
     time as such conversion has been effected, the rights of the holder of such
     Preferred Stock as such holder will cease and the Person or Persons in
     whose name or names any certificate or certificates for shares of Common
     Stock are to be issued upon such conversion will be deemed to have been the
     holder or holders of record of the shares of Common Stock represented
     thereby.

               (b) As soon as possible after a conversion has been effected (but
     in any event within seven business days), Issuer (in the case of clause (i)
     below) will deliver to the converting holder:



                                      -8-
<PAGE>
 
               (i) A certificate or certificates representing the number of
          shares of Common Stock issuable by reason of such conversion in such
          name or names and such denomination or denominations as the converting
          holder has specified;

               (ii) Subject to the provisions of Section 3.3, payment of an
                                                 -----------
          amount equal to all accrued dividends with respect to each share of
          Preferred Stock converted, which have not been paid prior thereto;

               (iii)  A certificate representing any Preferred Stock which was
          represented by the certificate or certificates delivered to the
          Company in connection with such conversion but which was not covered.

          (c) Subject to the provisions of Section 3.3, if for any reason the
                                           -----------
Company is unable to pay any accrued dividends on the Preferred Stock being
converted, the Company will pay such dividends to the converting holder as soon
thereafter funds of the Company are legally available for such payment. At the
request of any such converting holder, the Company will provide such holder with
written evidence of its obligation to such holder.

          (d) The issuance of certificates for shares of Common Stock upon
conversion of Preferred Stock will be made without charge to the holder for any
issuance tax in respect thereof or other cost incurred by Issuer in connection
with such conversion and the related issuance of shares of Common Stock. Upon
conversion, Issuer will take all such actions as are necessary in order to
insure that the Common Stock issuable with respect to such conversion will be
validly issued, fully paid and nonassessable.

          (e) The Company will not close its books against the transfer of
Preferred Stock or of Common Stock issued or issuable upon conversion of
Preferred Stock in any manner which interferes with the timely conversion of
Preferred Stock.

     7.3  Conversion Price and Adjustments.
          ---------------------------------

          (a) The initial Conversion Price at which shares of Common Stock shall
be deliverable upon conversion of Preferred Stock will be $1.50 per share. The
initial Conversion Price is subject to adjustment as hereinafter provided.
Except as provided in this Certificate of Designation, no adjustment in the
Conversion Price shall be made in respect of the issuance of Additional Shares
unless the consideration per share for an Additional Share issued or deemed to
be issued by Issuer is less than the Conversion Price in effect on the date of,
and immediately prior to, such issue.

          (b) In the event Issuer at any time or from time to time after the
Original Issue Date shall issue any Options or Convertible Securities or shall
fix a




                                      -9-
<PAGE>
 
record date for the determination of holders of any class of securities entitled
to receive any such Options or Convertible Securities, then the following shall
apply:

              (i) The maximum number of shares of Common Stock issuable upon the
          exercise of such Options or, in the case of Convertible Securities and
          Options therefor, the conversion or exchange of such Convertible
          Securities, shall be deemed to be Additional Shares issued as of the
          earlier of (x) the time of such Options or Convertible Securities are
          issued or (y) in case such a record date shall have been fixed, as of
          the close of business on such record date; provided, that if such
          Options or Convertible Securities by their terms provide, with the
          passage of time or otherwise, for any change in the minimum amount of
          consideration payable to Issuer, or any change in the maximum number
          of shares of Common Stock issuable upon the exercise, conversion or
          exchange thereof other than changes which may occur as a result of
          anti-dilution provisions (for which each Conversion Price shall be
          readjusted based on the provisions of this Section 7.3 when each such
                                                     -----------
          change is effective), the consideration per share (determined pursuant
          to Section 7.3(e) hereof) for Common Stock issuable pursuant to such
             --------------
          Options or Convertible Securities shall be the minimum consideration
          per share that could at any time result, taking into consideration all
          subsequent changes in the minimum amount of consideration payable to
          Issuer and/or in the maximum number of shares of Common Stock issuable
          upon the exercise, conversion or exchange.

              (ii) No further adjustment in the Conversion Price shall be made
          upon the subsequent issue of Convertible Securities or shares of
          Common Stock upon the exercise of such Options or conversion or
          exchange of such Convertible Securities.

              (iii)  Upon the expiration of any such Options or any rights of
          conversion or exchange of such Convertible Securities which shall not
          have been exercised, the Conversion Price computed upon the original
          issue thereof (or upon the occurrence of a record date with respect
          thereto), and any subsequent adjustments based thereon, shall, upon
          such expiration, be recomputed (provided that recomputation shall not
          affect any Preferred Stock converted or tendered for conversion prior
          to such exercise or expiration) as if:

                    (A) in the case of Convertible Securities or Options for
              Common Stock, the only Additional Shares issued were shares of
              Common Stock, if any, actually issued upon the exercise of such
              Options or the conversion or exchange of such Convertible
              Securities and the consideration received therefor was the
              consideration actually received by Issuer for the issue



                                     -10-
<PAGE>
 
          of all such Options that were exercised plus the consideration
          actually received by Issuer upon such exercise, or for the issue of
          all such Convertible Securities which were actually converted or
          exchanged, plus the additional consideration, if any, actually
          received by Issuer upon such conversion or exchange; and

               (B) in the case of Options for Convertible Securities, only the
          Convertible Securities, if any, actually issued upon the exercise
          thereof were issued at the time of issue of such Options, and the
          consideration received by Issuer for the Additional Shares deemed to
          have been then issued was the consideration actually received by
          Issuer for the issue of all such Options that were exercised, plus
          the consideration deemed to have been received by Issuer upon the
          issue of the Convertible Securities with respect to which such Options
          that were actually exercised.

          (iv)   No readjustment pursuant to clause (iii) above shall have the
     effect of increasing the Conversion Price to an amount which exceeds the
     Conversion Price in effect immediately prior to the original adjustment If
     Additional Shares were issued between the original adjustment date and the
     readjustment date (other than Common Stock issued upon exercise of the
     Options or conversion of the Convertible Securities that are the subject to
     the readjustment), then the Conversion Price on the readjustment date shall
     be recomputed (but only if a lower Conversion Price results therefrom) by
     treating the readjusted Conversion Price as the Conversion Price in effect
     on the original adjustment date and adjusting such Conversion Price for all
     issuances of Additional Shares (other than Common Stock issued upon
     exercise of the Options or conversion of the Convertible Securities that
     are the subject of the readjustment).

     (c) The Conversion Price shall be adjusted in accordance with the following
provisions:

          (i) In the event Issuer at any time or from time to time after the
     Original Issue Date shall declare or pay any dividend on the Common Stock
     payable in Common Stock or effect a subdivision or combination of the
     outstanding shares of Common Stock (by reclassification or otherwise), then
     and in any such event, the Conversion Price shall be proportionately
     decreased in the case of a stock dividend or subdivision and
     proportionately increased in the case of a combination of shares effective,
     in the case of such dividend, immediately after the close of business on
     the record date for the determination of holders of Common Stock entitled
     to receive such dividend or, in the case of a subdivision or combination,
     at the close



                                     -11-
<PAGE>
 
      of business immediately prior to the date upon which such corporate action
      becomes effective.

          (ii) In the event Issuer shall at any time after the Original Issue
      Date issue Additional Shares (including Additional Shares deemed to be
      issued pursuant to Section 7.3(b)) other than Germany Shares, without
                         ---------------
      consideration or for a consideration per share less than the Conversion
      Price in effect on the date of and immediately prior to such issuance,
      then and in each such event, the Conversion Price shall be reduced
      concurrently with such issue of shares, to a price (calculated to the
      nearest cent) determined by multiplying such Conversion Price by a
      fraction, the numerator of which shall be the number of shares of Common
      Stock outstanding immediately prior to such issuance plus the number of
      shares of Common Stock which the aggregate consideration received by
      Issuer for the total number of Additional Shares so issued would purchase
      at the Conversion Price in effect immediately prior to such issuance, and
      the denominator of which shall be the number of shares of Common Stock
      outstanding immediately prior to such issuance plus the number of such
      Additional Shares so issued.  For the purpose of the above calculation,
      the number of shares of Common Stock outstanding immediately prior to such
      issuance shall be calculated on a fully diluted basis, as if all shares of
      Preferred Stock and all Options and Convertible Securities had been fully
      exercised or converted into shares of Common Stock immediately prior to
      such issuance (and the resulting securities fully convened into shares of
      Common Stock, if so convertible) as of such date, but not including in
      such calculation any additional shares of Common Stock issuable with
      respect to shares of Preferred Stock, Options or Convertible Securities
      solely as a result of the adjustment of the Conversion Price (or other
      conversion ratios) resulting from the issuance of the Additional Shares
      causing the adjustment in question.

          (iii)   In the event Issuer shall at any time after the Original Issue
     Date issue Germany Shares (including Germany Shares deemed issued pursuant
     to Section 7.3(b)), without consideration or for a consideration per share
        ---------------
     less than the Conversion Price in effect on the date of and immediately
     prior to such issuance, then and in each such event, the Conversion Price
     shall be reduced concurrently with such issue of shares to the price at
     which such Germany Shares are issued.

     (d) For purposes of this Section 7.3, the consideration received by Issuer
                              -----------
for the issue of any Additional Shares shall be computed as follows:

          (i) Insofar as it consists of cash, such consideration shall consist
     of the aggregate amount of cash received by Issuer excluding amounts paid
     or payable for accrued interest or accrued dividends.




                                     -12-
<PAGE>
 
               Insofar as it consists of property other than cash, such
               consideration shall be computed at the fair value thereof at the
               time of such issue, as determined in good faith by the Board of
               Directors of Issuer. In the event Additional Shares are issued
               together with other securities or other assets of Issuer for
               consideration which covers both, such consideration shall be the
               proportion of such consideration so received, computed as
               determined in good faith by the Board of Directors of Issuer.

                    (ii) For the purpose of computing the initial adjustment of
               each Conversion Price pursuant to Section 7.3(b)(i) the
                                                 -----------------
               consideration per share received by Issuer for additional Shares
               of Common Stock deemed to have been issued pursuant to Section
                                                                      -------
               7.3(b)(i) shall be determined by dividing the total amount, if
               ---------
               any, received or receivable by Issuer as consideration for the
               issue of such Options or Convertible Securities, plus the minimum
               aggregate amount of additional consideration payable to Issuer
               upon the exercise of such Options or the conversion or exchange
               of such Convertible Securities, or in the case of the Options for
               Convertible Securities, the exercise of such Options for
               Convertible Securities and the conversion or exchange of such
               Convertible Securities, by the maximum number of shares of Common
               Stock issuable upon the exercise of such Options or the
               conversion or exchange of such Convertible Securities.

               (e) In the event Issuer at any time or from time to time makes,
          or fixes a record date for the determination of holders of Common
          Stock entitled to receive a dividend or other distribution payable in
          securities of Issuer other than shares of Common Stock or any other
          property (including cash), then and in each such event provision shall
          be made so that each holder of Preferred Stock shall receive upon
          conversion thereof, in addition to the number of shares of Common
          Stock receivable thereupon, the amount of securities of Issuer or
          other property which he would have received had such holder's
          Preferred Stock been converted into Common Stock on the record date of
          such event and had the holder thereafter, during the period from the
          record date of such event to and including the date of conversion,
          retained such securities or other property (including cash) receivable
          by the holder as aforesaid during such period, subject to all other
          adjustments called for during such period under this Section 7.3 with
                                                               -----------
          respect to the rights of the holders of the Preferred Stock.

          7.4  No Impairment. Issuer will not, by amendment of its Certificate
               -------------
of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by Issuer, but will at all times
in good faith assist in the carrying out of all the provisions of this

or appropriate in order to protect the conversion rights of the holders of
Preferred Stock against impairment.

          7.5  Certificate as to Adjustments. Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Price pursuant to this Certificate
of Designation, Issuer at its expense, shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to the holders of
Preferred Stock a certificate setting forth such adjustment or readjustment and
show in detail the facts upon which such adjustment or readjustment is based.
Issuer shall, upon the written request at any time of any holder of Preferred
Stock, furnish or cause to be furnished to such holder a like certificate
setting forth (i) such adjustments and readjustments, (ii) each Conversion Price
at the time in effect, and (iii) the number of shares of Common Stock and the
amount, if any, of other property which at the time Would be received upon the
conversion of Preferred Stock.

          7.6  Reservation of Preferred Stock and Stock Issuable Upon
               ------------------------------------------------------
Conversation. Issuer shall at all times (any such time being referred to in this
- ------------
Section 7.6 as a "determination date") reserve and keep available out of its
- ----------- 
authorized but unissued shares of Preferred Stock solely for the purpose of
effecting the payments of dividends pursuant to Section 3.1, 675,000 shares of
Preferred Stock plus such number of additional shares of Preferred Stock, if
any, as shall be needed to pay by the issuance of additional Preferred Stock all
dividends which may accrue under Section 3.1 during the two-year period from any
determination date.  If at any time the number of authorized but unissued shares
of Preferred Stock shall not be sufficient to comply with the preceding
provisions of this Section 7.6, Issuer shall promptly take such corporate action
                   -----------
as may, in the opinion of its counsel, be necessary to increase its authorized
but unissued shares of Preferred Stock to such number of shares as shall be
required by the terms hereof. Issuer shall at all times reserve and keep
available out of its authorized but unissued shares of Common Stock solely for
the purpose of effecting the conversion of the Preferred Stock, such number of
its shares of Common Stock as shall from time to time be sufficient to effect a
conversion of all and, if at any time the number of authorized but unissued
shares of Common Stock shall not be sufficient to effect the conversion of all
shares of Preferred Stock, Issuer shall promptly take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Common Stock to such number of shares as shall be sufficient
for such purpose.

          7.7  Payment of Taxes.  Issuer shall pay all issue taxes and other
               ----------------
governmental charges (other than income or other taxes imposed upon profits
realized by the recipient) that may be imposed in respect of the issue or
delivery of shares of Common Stock or other securities or property upon
conversion of the Preferred Stock; provided, however that Issuer shall not be
obligated to pay any tax or other charge imposed in connection with any
transfer involved in the issue and delivery of shares of Common Stock or other
securities in any name other than that in which the shares of Preferred Stock
were registered.

          7.8  Reclassification: Recapitalization. In the event of any
               ----------------------------------
reclassification of the Common Stock or recapitalization involving Common Stock
(other than a change in



                                     -14-
<PAGE>
 
par value or as a result of a stock dividend, subdivision, or combination of
shares), each holder of Preferred Stock shall thereafter be entitled to receive
and provisions shall be made therefor in an agreement relating to the
reclassification or recapitalization, upon conversion of Preferred Stock, the
kind and number of shares of Common Stock or other securities or property
(including cash) of Issuer, to which such holder of Preferred Stock would have
been entitled if such holder had held the number of shares of Common Stock of
Issuer into which the shares of Preferred Stock held by such holder was
convertible immediately prior to such reclassification or recapitalization; and
in any such case appropriate adjustment shall be made in the application of the
provisions herein set forth with respect to the rights and interests thereafter
of the holders of the Preferred Stock; to the end that the provisions set forth
herein shall thereafter be applicable, as nearly as reasonably may be, in
relation to any shares, other securities, or property thereafter receivable upon
conversion of the Preferred Stock.

          7.9  Notices. In the event that the Issuer intends:
               -------

               (a) to declare any dividend or distribution upon its Common
          Stock, whether in cash, property, stock or other securities, whether
          or not a regular cash dividend and whether or not out of earnings or
          earned surplus;

               (b) to offer for subscription pro rata to the holders of any
          class or series of its stock any additional shares of stock of any
          class or series or other rights;

               (c) to effect any reclassification or recapitalization of its
          Common Stock outstanding involving a change in the Common Stock; or

               (d) to merge or consolidate With or into any other corporation,
          or sell, lease or convey all or substantially all its property or
          business, or to liquidate, dissolve or wind up.

THEN, in connection with each event and for the purpose of providing the holders
of Preferred Stock with an opportunity to elect to convert all or a portion of
the Preferred Stock held thereby in accordance with the other provisions of this
Certificate of Designation prior to the occurrence of any of the events or dates
described in clauses (a)-(d) above, Issuer shall send to each holder of
Preferred Stock:

          (A) at least 20 days prior written notice of the date on which a
          record shall be taken for such dividend, distribution or subscription
          rights (and specifying the date on which the holders of Common Stock
          shall be entitled thereto) or for determining rights to vote in
          respect of the matters referred to in (a) and (b) above; and

          (B) in the case of the matters referred to in (c) and (d) above, at
          least 20 days prior written notice of the date when the same shall
          take place (and specifying the date on which the holders of Common
          Stock shall be entitled




                                     -15-
<PAGE>
 
          to exchange their Common Stock for securities or other property
          deliverable upon the occurrence of such event or such earlier date, if
          any, on which a record shall be taken of the holders of Common Stock
          who shall be entitled to exchange their Common Stock).

          7.10  Manner of Notice.  Any notice required by this Certificate of
                ----------------
Designation shall be deemed given if given by certified mail, postage prepaid,
return receipt requested, addressed to the holder of Preferred Stock at the
address for each such holder as shown on the books of Issuer.

          7.11  Fractional Shares.  No fractional share shall be issued upon the
                -----------------
conversion of any portion of the Preferred Stock. All shares of Common Stock
(including fractions thereof) issuable upon conversion of Preferred Stock shall
be aggregated for purposes of determining whether the conversion would result in
the issuance of any fractional share. If, after such aggregation, the conversion
would result in the issuance of a fraction of a share of Common Stock, Issuer
shall, in lieu of issuing any fractional share, pay the holder otherwise
entitled to such fraction a sum in cash equal to the Market Price of such
fraction on the date of conversion.

     8.  Covenants. In addition to any other rights provided by law or
         ---------
agreement, so long as any share of Preferred Stock shall be outstanding, the
Company shall not, without first obtaining the affirmative vote or written
consent of the holders of not less than 60% of the outstanding shares of
Preferred Stock:

          8.1  amend or repeal any provision of, or add any provision to, the
Company's Certificate of Incorporation or bylaws if such action would alter or
change the preferences, rights, privileges or powers of, or the restrictions
provided for the benefit of the Preferred Stock, or increase or decrease the
number of shares of the Preferred Stock authorized hereby;

          8.2  authorize or issue shares of any class of stock having any
preference or priority as to dividends or assets superior to or on a parity
with any such preference or priority of the Preferred Stock, or authorize or
issue shares of stock of any class or any bonds, debentures, notes or other
obligations convertible into or exchangeable for, or having option rights to
purchase, any shares of any other class or series of stock of the Company having
any preference or priority as to dividends or assets superior to or on a parity
with any such preference or priority of the Preferred Stock;

          8.3  reclassify any Junior Stock into shares having any preference or
priority' as to dividends or assets superior to or on a parity with any such
preference or priority of the Preferred Stock:

          8.4  make any dividend payment (other than dividend payments in shares
of Common Stock or Preferred Stock) in respect of any shares of any class of
stock of the Company so long as any Preferred Stock remaining outstanding; or

     rules or regulations and to reimburse any such Indemnified Party for any
     legal or other expenses reasonably incurred by them in connection with
     investigating, settling or defending any action or claim in connection
     therewith (including, without limitation, court costs and reasonable
     attorneys' fees); provided, however, that the Company shall not be liable
                       --------  -------
     in any such case to the extent that any such loss, claim, damages or
     liability is found in a final judgement of a court of competent
     jurisdiction to have resulted from any such Indemnified Party's gross
     negligence, willful misconduct or bad faith in performing their services
     hereunder. If for any reason the foregoing indemnification is unavailable
     to an Indemnified Party, then the Company shall contribute to the amount
     paid or payable by that Indemnified Party as a result of such loss, claim,
     damage or liability in such proportion as is appropriate to reflect not
     only the relative benefits received by the Company on the one hand and the
     Indemnified Party on the other hand but also the relative fault of the
     Company and that Indemnified Party, as well as any relevant equitable
     considerations. The Company agrees to reimburse an Indemnified Party within
     ten days after presentation of any statement by that Indemnified Party for
     all reasonable expenses (including without limitation of the generality of
     the foregoing, fees and expenses of attorneys selected by each Indemnified
     Party) incurred in connection with any testimony the Indemnified Party or
     its employees are required to give (in court, before a regulatory agency,
     by deposition or otherwise) in any regulatory or court proceeding
     (including depositions), whether or not the Indemnified Party is a party,
     and which related directly or indirectly to the Opinion, the Sale of the
     Subsidiaries or the Merger with Alliance Resources, Inc.

2.   With respect to the foregoing Paragraph 1 of the indemnification, the
                                   -----------
     Company agrees that no Indemnified Party shall be deemed to have been
     grossly negligent for reasonably relying upon any written untrue statement
     or alleged omission of a material fact necessary to make the statements, in
     light of the circumstances in which made, not misleading, contained in or
     omitted from any information provided to any Indemnified Party by or on
     behalf of the Company or the Subsidiaries (including, without limitation of
     the generality of the foregoing, any accountant or attorney employed or
     retained by the Company or the Subsidiaries). The indemnification provided
     in the foregoing Paragraph 1 hereof shall extend upon the same terms and
                      -----------
     conditions to each person, if any, who may be deemed to control any
     Indemnified Party and shall be applicable, to the extent set forth herein,
     whether or not negligence of the person entitled to indemnification is
     alleged or proven.



<PAGE>
 
3.   In the event any action (with respect to which indemnity or reimbursement
     from the Company may be sought by any Indemnified Party on account of
     agreements contained herein) shall be brought or threatened against an
     Indemnified Party, prompt notice will be given to the Company in writing of
     such action, together with a copy of all papers served on, or received by,
     such Indemnified Party in connection with such action provided that failure
     to give such notice shall not affect such Indemnified Party's rights under
     these indemnification provisions, unless, and only to the extent that, such
     failure results in the Company's forfeiture of substantive rights or
     defenses. If such an event occurs the Company shall assume the defense of
     such action, including the employment of counsel and the payment of all
     expenses. Each Indemnified Party shall have the right to employ separate
     counsel in any such action and to participate in the defense thereof, but
     the fees and expenses of such counsel shall be at the expense of such
     Indemnified Party unless (a) the employment thereof has been specifically
     authorized by the Company in writing; (b) the Company has failed to assume
     the defense and employ counsel; or (c) named parties, or parties threatened
     to be named, to any such action (including any impleaded parties or parties
     threatened to be impleaded) include both such Indemnified Party and the
     Company, and the Indemnified Party has been advised by such counsel that
     there may be one or more legal defenses available to them which are
     different from or additional to those available to the Company (in which
     cases each Indemnified Party shall have the right to employ its own counsel
     and in such cases any reasonable fees and expenses of such counsel shall be
     paid by the Company). The Company shall not be liable for any settlement of
     any such action or proceeding effected without its written consent. If
     there shall be a final judgement for the plaintiff in such action or
     proceeding, the Company agrees to indemnify and hold harmless the
     Indemnified Party from and against any loss or liability by reason of such
     settlement or judgement.

                                          ------

Gentlemen:

     Reference is made to the Credit Agreement. Capitalized terms used, and not
otherwise defined herein, shall have the meanings set forth in the Credit
Agreement. LaTex Resources, Inc. ("LRI") and Enpro, Inc. ("Enpro"; together with
                                   ---                     -----
LRI, "Guarantors") are guarantors of the Obligations. After each of us has
      ----------
signed this letter, this letter agreement (the "First Amendment") shall
                                                ---------------
constitute a binding agreement between Borrowers, the Guarantors and the Lender.

     1.  The Lender and each of the Borrowers and Guarantors is party to that
certain Forbearance Agreement dated as of July 23, 1996 (the "Forbearance
                                                              -----------
Agreement").  Pursuant to the Forbearance Agreement, each of the Borrowers and
- ---------
Guarantors acknowledged and agreed that Borrowers and Guarantors were in default
in various

<PAGE>
 
LaTex Petroleum Corporation

respects in their respective obligations under the Credit Agreement and the
other Loan Documents.  Such Events of Default were defined in the Forbearance
Agreement as the  "Acknowledged Defaults". Pursuant to the Forbearance
                   ---------------------
Agreement, Borrowers and Guarantors requested, and the Lender agreed on the
terms and conditions set forth therein, that the Lender would forbear from the
exercise of its rights and remedies under the Credit Agreement and the other
Loan Documents, which rights and remedies would otherwise be available to the
Lender in respect of the Acknowledged Defaults.

     2. The Lender, Borrowers and Guarantors hereby agree that the conditions
precedent to the effectiveness of the Forbearance Agreement set forth in 
Section 5 of the Forbearance Agreement have been satisfied (except as to those
- ---------
items listed in Section 5 of this First Amendment that are, as of the date
                ---------
hereof, no longer conditions precedent) and that the Forbearance and the
Forbearance Period have become effective.

     3.  Except as specifically set forth in Section 4 hereof, (a) neither the
                                             ---------
execution of this First Amendment nor any negotiations or other actions
undertaken hereunder or pursuant hereto shall constitute a waiver or forbearance
of the rights of the Lender under the Credit Agreement or any other Loan
Document, and (b) the Lender shall retain all rights and remedies whatsoever to
which it may be entitled under the Credit Agreement or any other Loan Document.

     4.  The Lender, Borrowers and Guarantors hereby agree to amend the
Forbearance Agreement by deleting from the Forbearance Agreement Section 4
                                                                 ---------
thereof and substituting the following in its place:

     "4.  The Lender hereby agrees during the Forbearance Period (as defined
     below) to delay enforcement of the rights granted to Lender under the
     Credit Agreement and the other Loan Documents and applicable law arising as
     a result of the Acknowledged Defaults.  For purposes hereof, the
     enforcement delay granted by the Lender hereby is referred to as the
     "Forbearance" and the "Forbearance Period" shall mean the period beginning
      -----------           ------------------
     with October 15, 1996 and ending on the earliest of:

           in respect of any of its covenants or agreements, or the breach of
           any of its representations and warranties, contained in this First
           Amendment,

     c.    the occurrence of any Default or Event of Default under the Credit
           Agreement or any other Loan Document (other than the Acknowledged
           Defaults) with respect to any of the Borrowers or the Guarantors, and

     d.    the date on which each of the Acknowledged Defaults is cured to the
           satisfaction of the Lender."

     5.  The Lender, Borrowers and Guarantors hereby agree to amend the
Forbearance Agreement by adding a new Section 16 following the existing 
                                      ----------
Section 15 thereof as follows:

Future net revenue is the amount, exclusive of state and federal income taxes, 
which will accrue to the appraised interests from continued operation of the 
properties to depletion. It should not be construed as a fair market or trading 
value. No provision has been made for the cost of plugging and abandoning the 
properties nor for the value of salvable equipment.


No attempt has been made to quantify or otherwise account for any accumulative 
gas production imbalances that may exist. Neither has an attempt been made to 
determine whether the wells and facilities are in compliance with various 
governmental regulations, nor have costs been included in the event they are 
not.


This report consists of three volumes. Volume 1 includes various summaries.
These include summary forecasts of annual gross and net production, severance
and ad valorem taxes, operating income and net revenue by reserve type on
Schedule No. 1. Schedule No, 2 is a sequential listing of the individual
properties based on discounted future net revenue. An alphabetical one-line
summary by property is reflected on Schedule No. 3. A geographical one-line
summary by state and field is shown on Schedule No. 4. Volumes II and III
include individual lease forecasts and production decline curves.


CLASSIFICATION OF RESERVES
- --------------------------


Reserves attributed to the appraised leases have been classified "proved 
developed producing," "proved developed non-producing," "proved developed 
behind-pipe," "proved undeveloped primary," "probable developed primary," 
"probable undeveloped primary," "possible developed primary," and "possible 
undeveloped primary."


Proved Developed Producing Reserves are those reserves expected to be recovered 
- -----------------------------------
from currently producing zones under continuation of present operating methods. 
This category may also include recently completed shut-in gas wells schedule for
connection to a pipeline in the near future.


Proved Developed Non-Producing Reserves are those reserves expected to be 
- ---------------------------------------
recovered from zones capable of producing but which are shut-in because no 
market outlet exists at the present time or whose date of connection to a 
pipeline is uncertain.


Proved Developed Behind-Pipe Reserves are those reserves currently behind the 
- -------------------------------------
pipe in existing wells which are considered proved by virtue of successful 
testing or production in offsetting wells.


Proved Undeveloped Primary Reserves are those reserves attributable to wells to 
- -----------------------------------
be drilled at locations which can be considered proved by virtue of favorable 
structural position and which can be anticipated with a high degree of 
certainty.


Probable Developed Primary Reserves are those reserves anticipated from zones 
- -----------------------------------
behind the pipe in existing wells which exhibit favorable reservoir 
characteristics based on core and/or log analyses but which have not been 
physically tested or are not producing in offsetting wells. These reserves are 
somewhat speculative.


Probable Undeveloped Primary Reserves are those reserves anticipated from wells 
- -------------------------------------
to be drilled at locations that must be considered somewhat speculative because 
of limited geologic control.


Possible Developed Primary Reserves are those reserves based on criteria similar
- -----------------------------------
to those discussed under "probable developed primary" reserves but which must be
considered more speculative.


Possible Undeveloped Primary Reserves are those reserves anticipated from wells 
- -------------------------------------
to be drilled on structures with limited development whose productive limits 
have not be delineated. These reserves must be considered quite speculative.

ESTIMATION OF RESERVES
- ----------------------

The majority of the appraised wells have been producing for a considerable 
length of time. Reserves attributable to wells with a well-defined production 
and/or pressure decline trend were based upon extrapolation of that trend to an 
economic limit and/or abandonment pressure.

Reserves anticipated from new wells or undeveloped locations were based upon 
volumetric calculations or analogy with similar properties which are producing 
from the same horizons in the respective areas. Structural position, net pay 
thickness, well productivity, gas-oil ratios, water production, pressures, and 
other pertinent factors were considered in the estimations of these reserves.

Reserves assigned to behind-pipe zones have been estimated based on volumetric 
calculations and/or analogy with other wells in the area producing from the same
horizon.

FUTURE NET REVENUE
- ------------------

Oil Income
- ----------

In accordance with your request, income from the sale of oil was estimated using
a base price of $19.74 per barrel for each lease. Historical differences between
the price received at each property and the West Texas Intermediate posted price
were calculated. This differential was applied to the base price for each lease.
This price was held constant throughout the life of each lease. Adjustments were
made for state severance and ad valorem taxes where applicable.


Gas Income
- ----------

As requested, income from the sale of gas was based upon an initial Henry Hub
price of $2.66 per MMBTU. Historical differences between the price received at
each property and the Henry Hub prices were calculated. This differential, which
includes any BTU adjustment applicable, was applied to the initial Henry Hub
price for each lease. These prices were held constant throughout the life of
each lease. Adjustments were made for state severance and ad valorem taxes where
applicable.

Operating Expenses
- ------------------

Operating expenses were based upon actual operating costs charged by the 
respective operators as supplied by the staff of LaTex Resources, Inc. or were 
based upon the actual experience of the operators in the respective areas. These
expenses have been held constant throughout the life of each lease.

GENERAL
- -------
     
Information upon which this appraisal has been based was furnished by the staff
of LaTex Resources, Inc. or was obtained by us from outside sources we consider
to be reliable. This information is assumed to be correct. No attempt has been
made to verify title or ownership of the appraised properties.

Leases were not inspected by a representative of this firm, nor were the wells
tested under our supervision; however, the performance of the majority of the
wells was discussed with employees of LaTex Resources, Inc.

This report has been prepared utilizing methods and procedures regularly used by
petroleum engineers to estimate oil and gas reserves for properties of this type
and character. The recovery of oil and gas reserves and projection of producing
rates are dependent upon many variable factors including prudent operation,
compression of gas when needed, market demand, installation of lifting
equipment, and remedial work when required.

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


The reserves included in this report have been based upon the assumption that 
the wells will continue to be operated in a prudent manner under the same 
conditions existing at the present time. Actual production results and future 
well data may yield additional facts, not presently available to us, which will 
require an adjustment to our estimates.

The reserves included in this report are estimates only and should not be 
construed as being exact quantities. They may or may not be actually recovered, 
and, if recovered, the revenues therefrom and the actual costs related thereto 
could be more or less than the estimated amounts. As in all aspects of oil and 
gas evaluation, there are uncertainties inherent in the interpretation of 
engineering data and, therefore, our conclusions necessarily represent only 
informed professional judgments.

State regulatory authorities could, in the future, change the allocation of 
reserves allowed to be produced from a particular well any reservoir, thereby 
altering the material premise upon which our reserve estimate may be based.

Graphs showing past production and estimated future performance of the 
individual properties precede the respective cash flow projections. Estimates of
future performance shown on the graphs were made prior to the economic 
determinations. These forecasts may extend beyond the calculated economic limits
reflected by the cash flow projections.

The projection of cash flow has been made assuming constant prices. There is no 
assurance that prices will not vary. For this reason and those listed in the 
previous paragraph, the future net cash from the sale of production from the 
appraised properties may vary from the estimates contained in this report.

The information developed during the course of this investigation, basic data, 
maps and worksheets showing recovery determinations are available for inspection
in our office.

This report is to be used only in its entirety. Individual cash flow projections
are not to be distributed unless accompanied by this letter.

We appreciate this opportunity to be of service to you.

                                        Very truly yours,
