                                                          SEC File No. 333-19013
 
LATEX RESOURCES, INC.                                    ALLIANCE RESOURCES PLC

                MERGER PROPOSAL -- YOUR VOTE IS VERY IMPORTANT

     The Boards of Directors of LaTex Resources, Inc. and Alliance Resources Plc
have agreed on a merger intended to create an oil and gas exploration,
development and production company with greater opportunity for growth through
domestic acquisitions and participation in foreign concessions than either of
the companies could achieve separately. The combined company will be named
Alliance Resources Plc; its executive office will be in London, England and its
principal U.S. offices will be in Tulsa, Oklahoma.

     If the merger is completed, the Alliance Stock will be "reverse split" so
that each Alliance shareholder at the time of the merger will receive one New
Alliance Share for each 40 Existing Alliance Shares and each LaTex shareholder
at the time of the merger will receive 0.85981 of a New Alliance Share for each
share of LaTex Common Stock then held, 2.58201 New Alliance Shares for each
share of LaTex Series A Stock then held, 6.17632 New Alliance Shares for each
share of LaTex Series B Stock then held, and a warrant to purchase 0.85981 of a
New Alliance Share for each share of LaTex Common Stock subject to warrants
issued by LaTex then held. The New Alliance Shares to be issued to LaTex
shareholders will represent approximately 72% of the outstanding stock of
Alliance after the merger. The New Alliance Shares held by Alliance shareholders
will represent approximately 28% of the outstanding stock of Alliance after the
merger. If Alliance also issues New Alliance Shares, Bank Notes and Bank
Warrants to LaTex's bank in payment of certain fees and in exchange for an
overriding royalty interest held by the bank, as it has agreed in principle to
do, the bank will hold additional New Alliance Shares amounting to approximately
4.8% of outstanding stock of Alliance and will hold convertible notes and
warrants convertible or exercisable into additional shares amounting to
approximately 6.8% of the then outstanding stock of Alliance.

     The merger cannot be completed unless the shareholders of both companies
approve it.  This document is being furnished only to the LaTex shareholders,
however, as the Alliance shareholders are receiving a separate document prepared
under English law.  Both LaTex and Alliance have scheduled special meetings for
their respective shareholders to vote on the merger.  YOUR VOTE IS VERY
IMPORTANT.

     The Board of Directors of LaTex Resources, Inc., by unanimous vote of the
Board and of the independent Directors, have approved the Merger Agreement and
authorized the Merger and unanimously recommend that you vote FOR the adoption
of the Merger Agreement and authorization of the Merger.

     Whether or not you plan to attend the LaTex meeting, please take the time
to vote by completing and mailing the enclosed proxy card to us.  If you sign,
date and mail your proxy card without indicating how you want to vote, your
proxy will be counted as a vote in favor of the merger.  If you fail to return
your card, your proxy will be counted as a vote against the merger.

     The date, time and place of the special meeting of the LaTex shareholders
is:

                                         9 a.m., Local Time
                                         April 30, 1997

proposed merger.  In addition, you may obtain information about both LaTex and
Alliance from documents that we have filed with the Securities and Exchange
Commission ("SEC").  We encourage you to read this entire document carefully.

                             QUESTIONS AND ANSWERS
                        ABOUT THE ALLIANCE/LATEX MERGER

Q:   WHY ARE THE TWO COMPANIES PROPOSING TO MERGE? HOW WILL I BENEFIT?

A:   This merger has been approved by the Boards of both LaTex and Alliance as a
     means to create an independent oil company that has a larger interest in
     U.S. properties than either of the separate companies currently have,
     which, with the potential improvements to cash flow and greater prospect
     for financial leverage that this base provides, is anticipated to have a
     greater ability to participate in additional domestic and international oil
     and gas projects. We believe that the merger will allow the combined
     companies to pursue opportunities that would otherwise be unavailable or
     incapable of being exploited by either company separately. Management of
     Alliance intends to focus particularly on opportunities in the United
     States, the former Soviet Union and the Middle East, but will consider
     opportunities throughout the world. Of course, there is no guarantee that
     the combined companies will be successful in their efforts.

Q:   WHAT DO I NEED TO DO NOW?

A:   Mail your signed proxy card in the enclosed return envelope as soon as
     possible, so that your shares may be represented at the LaTex special
     meeting which will take place April 30, 1997. The Board of Directors of
     LaTex unanimously recommends voting in favor of the proposed merger.

Q:   PLEASE EXPLAIN THE EXCHANGE RATIO.

A:   At the time of the merger, LaTex shareholders will receive 0.85981 of a New
     Alliance Share for each share of LaTex Common Stock they hold, 2.58201 New
     Alliance Shares for each share of LaTex Series A Stock they hold, 6.17632
     New Alliance Shares for each share of LaTex Series B Stock they hold, and a
     warrant to purchase 0.85981 of a New Alliance Share for each share of LaTex
     Common Stock subject to warrants issued by LaTex they hold. Fractional New
     Alliance Shares will not be issued in the merger. Instead, the shares
     issued to each holder will be rounded to the nearest whole number of New
     Alliance shares. No cash will be paid for fractional shares not received.

     Example: if you currently own 100 shares of LaTex Common Stock, then after
     the merger you will be entitled to receive 86 New Alliance Shares.

Q:   WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A:   The Boards of Directors of both companies are working towards completing
     the merger as quickly as possible. In addition to shareholder approvals, we
     must also obtain regulatory approvals in both countries. We hope to
     complete the merger as early as April 30, 1997.

Q:   WHAT ARE THE TAX CONSEQUENCES TO LATEX SHAREHOLDERS OF THE MERGER?

A:   The exchange of LaTex shares by LaTex shareholders in the merger into New
     Alliance Shares will be taxable. The taxable income or loss each LaTex
     shareholder must recognize will generally be equal to the amount that the
     middle market quotation as derived from the Daily Official List of the
     London Stock Exchange of the New Alliance Shares held by a shareholder
     immediately after the merger exceeds the shareholder's tax basis in the
     LaTex Shares. To review the tax consequences to shareholders in greater
     detail, see page 69.

Q:   HOW ARE THE ALLIANCE SHARES BEING CHANGED?

A:   As part of the merger, the Alliance shareholders are being asked to approve
     a 40-to-1 reverse stock split of the Alliance stock. It is a condition to
     the merger that this reverse stock split be approved by the Alliance
     shareholders. Therefore, in connection with the merger, each 40 Existing
     Alliance Shares held by an Alliance shareholder at the time of the merger
     will be converted into one New Alliance Share. In this Proxy Statement, all
     references to the New Alliance Shares mean the Alliance shares after this
     reverse stock split.

Q:   HOW DO I REVOKE MY PROXY IF I DECIDE TO DO SO?

A:   You have the unconditional right to revoke your proxy at any time before
     your shares are voted. You can revoke the proxy either by appearing in
     person and notifying the officials at the special meeting that you wish to
     revoke your proxy or by notifying LaTex in writing addressed to: 4200 East
     Skelly Drive, Suite 1000, Tulsa, Oklahoma 74135, Attention: Stacey D.
     Smethers, Secretary. Your revocation will not be effective unless it has
     been received by the Secretary of LaTex before the day of the special
     meeting or by the officials in charge of the special meeting before the
     shares are voted.

Q:   HOW DO I DISSENT AND SEEK AN APPRAISAL OF MY SHARES IF I WISH TO DO SO?

A:   If you wish to dissent from the merger and receive the fair value of your
     LaTex shares in cash, you must deliver to LaTex, before the special
     meeting, a written demand for the appraisal of your LaTex Shares. This
     demand must reasonably inform LaTex of your identity and that you intend to
     demand the appraisal of your shares. You also must not vote in favor of the
     merger. After the vote on the merger, you must then follow additional steps
     to obtain the appraisal of your shares. See page 33 for additional
     information concerning your dissent and appraisal rights and how to pursue
     those rights.

Q:   SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A:   No. After the merger is completed, we will send you written instructions
     for exchanging your share certificates.

                            ALLIANCE RESOURCES PLC

     THIS DOCUMENT SERVES AS A PROSPECTUS FOR SHARES OF ALLIANCE RESOURCES PLC
AND ALSO AS A PROXY STATEMENT FOR A SPECIAL MEETING OF SHAREHOLDERS OF LATEX
RESOURCES, INC. TO BE HELD ON APRIL 30, 1997

     This Proxy Statement relates to 21,448,787 ordinary shares of (Pounds)0.40
each (the "New Alliance Shares") in the capital of Alliance Resources Plc
("Alliance") that may be issued to the shareholders of LaTex Resources, Inc.
("LaTex") in exchange for the outstanding shares of its common and preferred
stock, par value $.01 per share (the "LaTex Shares"), pursuant to an Agreement
and Plan of Merger (the "Merger Agreement") providing for the merger (the
"Merger") of Alliance Resources (Delaware), Inc. ("Alliance Delaware"), a newly
formed wholly owned subsidiary of Alliance, into LaTex, and are being offered
subject to the approval of the shareholders of LaTex and subject to the
satisfaction of the other conditions set forth herein and in the Merger
Agreement. A copy of the Merger Agreement is attached as Appendix B to this
Proxy Statement. This Proxy Statement also relates to warrants (the "New
Warrants") to be issued by Alliance in the Merger to replace currently
outstanding warrants issued by LaTex to purchase 2,242,250 shares of LaTex
Common Stock, and to 1,927,908 New Alliance Shares issuable upon exercise of
those New Warrants. The Merger and the Merger Agreement are to be submitted to a
vote of the shareholders of LaTex at a special meeting to be held on April 30,
1997. If the Merger is completed, the outstanding LaTex Shares (other than
shares, if any, held by LaTex in treasury and shares held by dissenters) will be
automatically canceled and LaTex shareholders will receive New Alliance Shares
at the rate provided in the Merger Agreement (the "Conversion Rate"). See "The
Merger--Terms of the Merger." This document also serves as a Prospectus with
respect to up to 2,578,125 New Alliance Shares and warrants (the "Bank
Warrants") that may be converted into or exercised for 1,210,938 additional New
Alliance Shares and the New Alliance Shares issuable upon exercise of the Bank
Warrants.

     The currently outstanding Alliance shares (the "Existing Alliance Shares")
are traded on the London Stock Exchange under the symbol "ARS." In connection
with the Merger, the Existing Alliance Shares will be subject to a 40-to-1
reverse split, pursuant to which each 40 Existing Alliance Shares will be
consolidated into one New Alliance Share of (Pounds)0.40 each. In view of the
size of the Merger relative to Alliance, the London Stock Exchange, at
Alliance's request, has suspended trading in the Existing Alliance Shares until
the Merger is completed. LaTex's Common Stock is traded on the Nasdaq SmallCap
Market ("Nasdaq") under the symbol LATX. On August 9, 1996, the last trading day
before the announcement of the Merger Agreement, the middle market quotation (as
derived from the Daily Official List of the London Stock Exchange) for the
Existing Alliance Shares was (Pounds)0.02 ($0.032) per share (equivalent to
(Pounds)0.80 ($1.28) per New Alliance Share) and the last reported sale price on
Nasdaq for LaTex's Common Stock was $0.41 per share. On March 14, 1997, the last
reported sale price for LaTex's Common Stock as reported by Nasdaq was $0.344
per share.

     SEE "RISK FACTORS" BEGINNING ON PAGE 9 FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS.

OUR REASONS FOR THE MERGER (SEE PAGE 18)

          The combined company will have a larger interest in U.S. properties
than either of the separate companies and, with the potential improvements to
cash flow and greater prospect for financial leverage that this base provides,
is anticipated to have a greater ability to participate in domestic and
international projects. In particular, the management and Boards of Directors of
both companies believe that the Merger will allow the combined company to pursue
development and acquisition projects that would otherwise be unavailable or
incapable of being exploited by either company separately. Following the Merger,
management of Alliance intends to focus particularly

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

                                       1
<PAGE>
 
- --------------------------------------------------------------------------------

on opportunities in the United States, the former Soviet Union and the Middle
East, but will consider acquisitions throughout the world. Of course, there is
no guarantee that the combined company will be successful in its efforts.

          Management of both LaTex and Alliance are confident that the two
companies may be combined efficiently. The combined company's headquarters will
be located in Alliance's current London offices, which will provide greater
access to international opportunities, while LaTex's Tulsa office will become
headquarters for domestic operations by integrating Alliance's smaller U.S.
operation. In recommending the Merger to its shareholders, LaTex's Board of
Directors considered a number of factors, including (a) the strategic aspects of
a merger with Alliance; (b) the worsening financial condition of LaTex; (c)
management's unsuccessful attempts to secure additional debt and/or equity
financing; (d) the difficulties of continuing to operate as a small independent
oil and gas company in the face of increasing competition for domestic and
international opportunities; and (e) the difficulty of significantly increasing
the company's assets, revenue or cash flow by pursuing only domestic projects.

RECOMMENDATION TO LATEX SHAREHOLDERS (SEE PAGE 38)

          The LaTex Board of Directors believes that the Merger is in your best
interest and unanimously recommends that you vote FOR the proposal to approve
and adopt the Merger Agreement and the Merger.

THE MERGER (SEE PAGE 22)

          The Merger Agreement is attached as Appendix B to this Proxy
Statement. The LaTex Board of Directors encourages you to read the Merger
Agreement as it is the legal document that governs the Merger.

          As part of the Merger, the Alliance shareholders are being asked to
approve a 40-to-1 reverse stock split of the Existing Alliance Shares.  It is a
condition to the Merger that this reverse stock split be approved by the
Alliance shareholders.  Therefore, in connection with the Merger, each 40
Existing Alliance Shares of (Pounds)0.01 each at the time of the Merger will be
consolidated into one New Alliance Share of (Pounds)0.40 each.  In this Proxy
Statement, all of the references to the New Alliance Shares mean the Alliance
stock after this reverse stock split.

WHAT LATEX SHAREHOLDERS WILL RECEIVE (SEE PAGE 22)

          Alliance will issue up to 21,448,787 New Alliance Shares to LaTex
shareholders in the Merger. At the time of the Merger, LaTex shareholders will
receive 0.85981 of a New Alliance Share for each share of LaTex Common Stock
they hold, 2.58201 New Alliance Shares for each share of LaTex Series A Stock
they hold, 6.17632 New Alliance Shares for each share of LaTex Series B Stock
they hold, and a New Warrant to purchase 0.85981 of a New Alliance Share for
each share of LaTex Common Stock subject to warrants issued by LaTex outstanding
at the time of the Merger. No fractional shares will be issued. Instead, the
shares issued to each holder will be rounded to the

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

                                       2
<PAGE>
 
- --------------------------------------------------------------------------------

nearest whole number of New Alliance Shares. No cash will be paid for fractional
shares not received.

          You should not send in your stock certificates until instructed to do
so after the Merger is completed.

OWNERSHIP OF THE NEW ALLIANCE FOLLOWING THE MERGER (SEE PAGE 39)

          The New Alliance Shares issued to LaTex shareholders in the Merger
will constitute approximately 73% of the outstanding common stock of Alliance
immediately after the Merger.  In addition, persons who hold warrants at the
time of the Merger to purchase LaTex Shares will receive New Warrants to
purchase 1,927,908 New Alliance Shares, or approximately 6.1% of the New
Alliance Shares outstanding after the Merger, and assuming exercise of all of
the New Warrants. If Alliance also issues New Alliance Shares, Bank Notes and
Bank Warrants to LaTex's bank in payment of certain fees and in exchange for an
overriding  royalty interest held by the bank, as it has agreed in principle to
do, the bank will hold additional New Alliance Shares amounting to approximately
4.8% of outstanding stock of Alliance and will hold convertible notes and
warrants convertible or exercisable into additional shares amounting to
approximately 6.8% of the then outstanding stock of Alliance.

BOARD OF DIRECTORS AND MANAGEMENT OF THE NEW ALLIANCE FOLLOWING THE MERGER (SEE
PAGE 64)

          It is expected by the current management and the Board of Directors of
both companies that after the Merger is completed John A. Keenan will continue
as Managing Director of the new Alliance, Paul R. Fenemore will continue as
Director of Operations and Business Development of the new Alliance, and H.
Brian K. Williams will continue as Finance Director of the new Alliance.  The
current Board of Directors of Alliance will comprise the Board of Directors of
the new Alliance with the addition of two LaTex members to a total of 10
members. Upon completion of the Merger, Jeffrey T. Wilson will resign from his
position as LaTex's Chief Executive Officer. Mr. Wilson and John R. Martinson,
both directors of LaTex, will become non-executive directors of the new
Alliance.

CONDITIONS TO THE MERGER (SEE PAGE 23)

          The completion of the Merger depends upon meeting a number of
conditions, including the following:

          (a)  approvals by the holders of a majority of the voting stock of
               each of Alliance and LaTex.

          (b)  the approval of governmental authorities and the London Stock
               Exchange;

          (c)  the absence of any change in or affecting either of the companies
               that causes a material adverse effect on either of them; and

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

                                       3
<PAGE>
 
- --------------------------------------------------------------------------------

          (d)  the number of LaTex shareholders demanding an appraisal of their
               shares prior to the LaTex Special Meeting not exceeding 5% of any
               class of the outstanding LaTex Shares.

          The condition limiting the level of shareholders demanding an
appraisal of their LaTex Shares may be waived by both Alliance and LaTex.

TERMINATION OF THE MERGER AGREEMENT (SEE PAGE 24)

          The Boards of Directors of either LaTex and Alliance have the right to
terminate the Merger Agreement without completing the Merger, and either party
can terminate the Merger Agreement if any of the following occurs:

          (a)  the Merger is not completed by April 30, 1997; or

          (b)  the approval of the holders of a majority of the stock of either
               Alliance or LaTex is not received; or

          (c)  a court or other relevant governmental authority prohibits the
               Merger; or

          (d)  the other party breaches or materially fails to comply with any
               of its representations or warranties or obligations under the
               Merger Agreement; or

          (e)  the Board of Directors of the other party either: (i) withdraws
               or modifies in any adverse manner its approval or recommendation
               in favor of the Merger, or (ii) approves or recommends a
               significant transaction with a third party; or

          (f)  the business of the other party materially changes for the worse;
               or

          (g)  the Board of Directors of either company determines, under
               certain circumstances, that the board's fiduciary obligations
               require acceptance of an offer from a third party to enter into a
               significant transaction.

TERMINATION FEES (SEE PAGE 24)

          The Merger Agreement requires Alliance or LaTex to pay to the other a
termination fee of $1 million, plus expenses, if the Merger terminates under
certain circumstances, including a determination by the Board of Directors of
Alliance or LaTex to accept an offer from a third party to enter into a
significant transaction with a third party.

OTHER INTERESTS OF OFFICERS AND DIRECTORS IN THE MERGER (SEE PAGE 26)

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

                                       4

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

          In considering the Board's recommendation that you vote in favor of
the Merger, you should be aware that Jeffrey T. Wilson, LaTex's Chief Executive
Officer, will have a consulting agreement with Alliance that will provide him
with interests in the Merger that are different from, or in addition to, yours.
In addition, John R. Martinson, a director of LaTex, is a principal in Wood
Roberts, LLC, which on completion of the Merger will receive a fee for rendering
the fairness opinions and other services in connection with the Merger.

ACCOUNTING TREATMENT (SEE PAGE 26)

          The Board of Directors of LaTex expects the Merger to be treated as a
purchase for accounting and financial reporting purposes.  For US GAAP purposes,
because LaTex is the larger company, this means that the transaction will be
treated as if LaTex had acquired and assumed the operations of Alliance at the
Effective Time of the Merger.

          The combined company will adopt Alliance's year end, which is April
30.

OPINION OF FINANCIAL ADVISOR (SEE PAGE 19)

          In deciding to approve the Merger, the LaTex Board of Directors
considered opinions provided by LaTex's financial advisor, Wood Roberts, LLC.
("Wood Roberts"), as to the fairness to the LaTex shareholders of the terms of
the Merger from a financial point of view. These opinions are attached as
Appendix C to this Proxy Statement. We encourage you to read these opinions.
The payment  of Wood Roberts' fees for rendering the fairness opinions and other
matters in  connection with the Merger is contingent upon completion of the
Merger.

          In connection with delivering these opinions, Wood Roberts performed a
variety of analyses.  These included comparing the relative oil and gas reserve
values and net assets of Alliance and LaTex and comparing the financial results
and historical stock prices of LaTex and Alliance to those of other selected oil
and gas companies traded on the London Stock Exchange.

MATERIAL TAX CONSIDERATIONS (SEE PAGE 69)

          The exchange of LaTex Shares by LaTex shareholders in the Merger into
New Alliance Shares will be taxable under United States tax law.  The taxable
income or loss each LaTex shareholder must recognize will generally be equal to
the amount by which the market value of the New Alliance Shares held by a
shareholder immediately after the Merger differs from the shareholder's basis in
the LaTex Shares.

RESTRICTIONS ON RESALES (SEE PAGE 33)

          There are certain restrictions on resales of New Alliance Shares to be
received by affiliates of LaTex in the Merger.

DISSENT AND APPRAISAL RIGHTS (SEE PAGE 33)

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

                                       5
<PAGE>
 
          Under Delaware law, any LaTex shareholder will have the right to
demand an appraisal of, and a cash payment for the fair value of, his LaTex
Shares by delivering to LaTex before the Special Meeting a written demand for
appraisal. This demand must reasonably inform LaTex of the shareholder's
identity and that the shareholder intends to demand the appraisal of his shares.
The shareholder must then follow the other requirements for demanding an
appraisal.

COMPARATIVE PER SHARE MARKET PRICE INFORMATION (SEE PAGE 36)

          The Existing Alliance Shares are traded on the London Stock Exchange
and are not traded in the United States.  On August 9, 1996, the last full
trading day on the London Stock Exchange prior to the public announcement of the
Merger Agreement, Alliance stock closed at (Pounds)0.02 ($0.032) per Existing
Alliance Share (equivalent to (Pounds)0.80 ($1.28) per New Alliance Share).  At
the request of Alliance, the London Stock Exchange has suspended the Existing
Alliance Shares from trading since the announcement of the Merger.

          LaTex Common Stock is traded and quoted on the Nasdaq SmallCap Market.
On August 9, 1996, LaTex Common Stock closed at $0.41 per share on Nasdaq.  On
March 14, 1997, LaTex Common Stock closed at $0.344 on Nasdaq.

LISTING OF ALLIANCE SHARES (SEE PAGE 36)

          Based on their knowledge of the prices and share trading activity of
small independent oil and gas companies on the London Stock Exchange, Alliance
and LaTex believe that the trading market for small independent oil and gas
companies is generally more favorable in London than in the U.S. This belief is
supported by the analysis of Wood Roberts described in detail under "The Merger-
Opinion of LaTex's Financial Advisor."  Therefore, Alliance is applying for
listing on the London Stock Exchange of the New Alliance Shares to be issued in
connection with the Merger. See "The Merger-Opinion of LaTex's Financial
Advisor." Of course, there is no assurance that the trading market for New
Alliance Shares on the London Stock Exchange will be more favorable than the
current market for LaTex Common Stock in the U.S. Alliance does not intend to
list the New Alliance Shares on any United States stock exchange or the Nasdaq
National Market System or SmallCap Market, but anticipates that the New Alliance
Shares may be traded from time to time over the counter. Quotations for shares
listed on the London Stock Exchange are not generally readily available in
newspapers or other publications in the United States, but are available in the
daily U.S. edition of the Financial Times. However, investors may place orders
for the purchase or sale of shares traded on the London Stock Exchange through
most licensed broker dealers in the United States. Under current U.K. law, the
transfer of New Alliance Shares will generally give rise to a liability to U.K.
stamp duty, normally at the rate of 50p for every (Pounds)100 (or part thereof)
of the actual consideration paid.

SUMMARY OIL AND NATURAL GAS RESERVE INFORMATION

  The net proved oil and natural gas reserve estimates as of April 30, 1996 with
respect to approximately 70% in value of Alliance's properties have been
prepared by Ryder Scott Company, independent petroleum engineers, with the
estimates for the remainder of Alliance's properties having been prepared by
internal engineers.  The net proved oil and natural gas reserve estimates as of
July 31, 1996, for LaTex have been prepared by Lee Keeling and Associates, Inc.,
independent petroleum engineers.

  Additional information about Alliance's and LaTex's oil and natural gas
reserves is discussed in "Risk Factors--Uncertainty of Estimates of Oil and
Natural Gas Reserves," "Alliance--Oil and Gas Properties," Note 11 to the
Consolidated Financial Statements of Alliance, "Supplemental Oil and Gas Data"
and "Item 1 and Item 2. Business and Properties" and Note 20 to the Consolidated

                                 RISK FACTORS

VOLATILITY OF OIL AND GAS PRICES AND SUPPLIES

  The revenues, profitability and future rates of growth of both Alliance and
LaTex are substantially dependent upon the price of, and demand for, oil,
natural gas and natural gas liquids.  Historically the markets for oil and
natural gas have been volatile and are likely to continue to be volatile in the
future. Prices for oil and natural gas are subject to wide fluctuations in
response to relatively minor changes in the supply of and demand for oil and
natural gas, market uncertainty and a variety of additional factors that are
beyond the control of the companies.  These factors include the level of
consumer product demand, weather conditions, availability of alternative fuels,
political conditions in the Middle East and other petroleum producing areas, the
foreign supply of oil and natural gas, the price of foreign imports and overall
economic conditions and domestic and foreign government negotiations.  It is
therefore impossible to predict future oil and natural gas price movements with
any certainty.  Declines in oil and natural gas prices would not only reduce the
combined company's cash flow, liquidity and profitability, but could also reduce
the combined amount of oil and natural gas that can be produced economically and
could, therefore, have a material adverse effect on the combined company's
financial condition, results of operations and reserves.  Although it is the
intention of Alliance management to hedge a substantial portion of the commodity
price risk associated with the combined company's production of oil and natural
gas to achieve some level of constant commodity pricing, the hedging policy for
the combined group has not yet been determined.  Alliance does not currently
engage in any hedging activity.  Therefore, its operations are fully exposed to
future changes in oil and gas prices.  In connection with the credit agreement
that Alliance will enter into at or before the time of the Merger, it will agree
to enter into hedging arrangements before July 1, 1997, on terms mutually
satisfactory to Alliance and the Bank of America.

  The availability of a ready market for oil and natural gas production also
depends on a number of factors, including the demand for and supply of oil and
natural gas and the proximity of reserves to, and the capacity of, oil and
natural gas gathering systems, pipelines or trucking and terminal facilities.
Wells may be temporarily shut in for lack of a market or due to inadequacy or
unavailability of pipeline or gathering system capacity.

NEED TO REPLACE RESERVES

  The combined company's future success depends on its ability to find, develop
or acquire additional oil and natural gas reserves that are recoverable on an
attractive economic basis.  Unless Alliance successfully replaces the reserves
that it produces (through development, exploration or acquisitions), its proved
reserves will decline.  Approximately 29.3% of the combined company's total
proved reserves at July 31, 1996 on a pro forma basis were either proved
undeveloped or proved developed non-producing. Recovery of such reserves will
require significant capital expenditures and successful drilling operations, and
there can be no assurance that Alliance will be successful in its effort to
develop or replace its proved reserves or that the combined company will have
success adding reserves at low finding and development costs.  Furthermore,
although the combined company's reserves may increase if oil and natural gas
prices increase, the combined company's finding costs for additional reserves
could also increase.

                                       11
<PAGE>
 
DRILLING AND OPERATING RISKS

  Drilling activities are subject to many risks, including the risk that no
commercially productive reservoirs will be encountered.  There can be no
assurance that new wells drilled by Alliance will be productive or that the
combined company will recover all or any portion of its investment.  Drilling
for oil and natural gas may involve unprofitable efforts, not only from dry
wells but from wells that are productive but do not produce sufficient net
revenues to return a profit after drilling, operating and other costs.  The cost
of drilling, completing and operating wells is often uncertain.  In addition,
the combined company's drilling operations may be curtailed, delayed or canceled
as a result of numerous factors, many of which are beyond the combined company's
control, including title problems, weather conditions, compliance with
governmental requirements and shortages or delays in the delivery of equipment
and services.

  Alliance's operations are and will continue to be subject to all of the risks
normally incident to the operation and development of oil and natural gas
properties and the drilling of oil and natural gas wells, including encountering
unexpected formations or pressures, blow-outs, the release of contaminants into
the environment, cratering and fires, all of which could result in personal
injuries, loss of life, damage to property of Alliance and others and the
imposition of fines and penalties pursuant to environmental legislation.  See
"Governmental and Environmental Regulation."  The combined company is not and
will not be fully insured against all of these risks, nor are all such risks
insurable, although Alliance maintains liability insurance in the amount of
$3,000,000, which it considers to be sufficient to cover reasonably foreseeable
occurrences.  However, the nature of these risks is such that liabilities could
exceed policy limits or, as in the case of environmental fines and penalties, be
uninsurable, in which event the combined company could incur significant costs
that could have a material adverse effect upon its financial condition. Alliance
believes that it has proper procedures in place and that its operating staff
carries out their work in a manner designed to mitigate these risks.

UNCERTAINTY OF ESTIMATES OF OIL AND NATURAL GAS RESERVES

  Estimates of proved developed oil and natural gas reserves and future net
revenues therefrom appearing elsewhere herein are based on reserve reports
prepared by independent petroleum engineers. The estimation of reserves requires
substantial judgment on the part of the petroleum engineers, resulting in
imprecise determinations, particularly with respect to new discoveries.
Different reserve engineers may make different estimates of reserve quantities
and revenues attributable thereto based on the same data. The accuracy of any
reserve estimate depends on the quality of available data as well as engineering
and geological interpretation and judgment. Results of drilling, testing and
production or price changes subsequent to the date of the estimate may result in
revisions to such estimates.

  The discounted future net cash flows referred to in this document should not
be construed as the current market value of the estimated oil and natural gas
reserves attributable to either company's properties.  In accordance with
applicable requirements of the SEC, the estimated discounted future net cash
flows from proved reserves are based on prices and costs as of the date of the
estimate, whereas actual future prices and costs may be materially higher or
lower.  Actual future net cash flows will also be affected by factors such as
the amount and timing of actual production, supply and

                                       12
<PAGE>
 
demand for oil and natural gas, curtailments or increases in consumption by
natural gas purchasers and changes in governmental regulations or taxation. The
timing of actual future net cash flows from proved reserves, and thus their
actual present value, will be affected by the timing of both the production and
the incurrence of expenses in connection with development and production of oil
and natural gas properties. In addition, the 10% discount factor, which is
required by the SEC to be used to calculate discounted future net cash flows for
reporting purposes, is not necessarily the most appropriate discount factor
based on interest rates in effect from time to time and risks associated with
either company or the oil and natural gas industry in general.

ACQUISITION RISKS

  After the Merger, Alliance intends to pursue acquisition opportunities on
terms management considers favorable.  There can be no assurance that suitable
acquisition candidates will be identified in the future, nor that they will be
integrated successfully into the combined company's operations or successful in
achieving desired profitability objectives.  In addition, Alliance will compete
against other companies for acquisitions, and there can be no assurance that it
will be successful in the acquisition of any material property interests.

  The successful acquisition of producing properties requires an assessment of
recoverable reserves, exploration potential, future oil and natural gas prices,
operating costs, potential environmental and other liabilities and other factors
beyond Alliance's control.  In connection with such an assessment, the combined
company will review the subject properties in a manner that it believes to be
generally consistent with industry practices.  Nonetheless, the resulting
assessments are necessarily inexact and their accuracy inherently uncertain, and
such a review may not reveal all existing or potential problems, nor will it
necessarily permit a buyer to become sufficiently familiar with the properties
to fully assess their merits and deficiencies.  Inspections may not always be
performed on every platform or well, and structural and environmental problems
are not necessarily observable even when an inspection is undertaken.

  Additionally, significant acquisitions can change the nature of the operations
and business of Alliance depending upon the character of the acquired
properties, which may be substantially different in operating and geologic
characteristics or geographic location than existing properties.  While it is
Alliance's current intent to concentrate on acquiring producing properties with
development and exploration potential, there is no assurance that Alliance will
not pursue acquisitions or properties with differing characteristics.

INTERNATIONAL ACQUISITIONS AND OPERATIONS

  Although Alliance's operations are currently conducted in the United States,
it is the intention of management after the Merger to explore and develop
projects both domestically and internationally, particularly in the former
Soviet Union and the Middle East. Such international operations are subject to
political, economic and other uncertainties, including, among others, risk of
war, revolution, border disputes, expropriation, renegotiation or modification
of existing contracts, import, export and transportation regulations and
tariffs, taxation policies, including royalty and tax increases and retroactive
tax claims, exchange controls, currency fluctuations and other uncertainties
arising out of foreign government sovereignty over the combined company's
potential operations.

                                       13
<PAGE>
 
Alliance's proposed international operations may also be adversely affected by
laws and policies of the United States affecting foreign trade, taxation and
investment. Furthermore, in the event of a dispute arising from international
operations, Alliance may be subject to the exclusive jurisdiction of foreign
courts or may not be successful in subjecting foreign persons to the
jurisdiction of courts in the United States or Great Britain.

SUBSTANTIAL CAPITAL REQUIREMENTS

  In the future, Alliance will require additional funds to develop, maintain and
acquire additional interests in existing or newly-acquired properties.
Historically, Alliance and LaTex have financed these expenditures primarily with
proceeds from debt and equity financings, cash provided by operating activities,
asset sales and sales of partial interests in international and domestic
concessions.  Alliance currently plans to increase capital expenditures from
approximately US$1.7 million in fiscal 1996 to approximately US$2.7 million in
fiscal 1997, principally for remedial and developmental capital expenditures for
the combined company's assets in Alabama, Mississippi and Louisiana.  Management
believes that, after debt service, it will have sufficient cash provided by
operating activities, availability under the Alliance Credit Agreement and asset
sales to fund planned capital expenditures in 1997. Alliance anticipates that
cash from operating activities and property sales will provide sufficient funds
to meet debt service requirements under the Alliance Credit Agreement with Bank
of America.  See "Alliance--Financing."  In addition, based on its knowledge of
the market for oil and gas properties and its recent property sales, Alliance
believes that it will be able to sell certain non-strategic properties for up to
$4.8 million during 1997.  Alliance intends to use the proceeds of these sales
to reinvest in the purchase and development of non-producing properties and to
reduce negative working capital.

  There can be no assurance that additional capital will always be available to
Alliance in the future or that it will be available on terms that are acceptable
to Alliance.  Should outside capital resources be limited, the rate of growth
would be adversely affected, and there can also be no assurance that Alliance
would be able to increase its oil and natural gas production or oil and natural
gas reserves. If revenues decrease as a result of lower oil and natural gas
prices or otherwise, Alliance may have limited ability to expend the capital
necessary to replace its reserves or to maintain production at current levels,
resulting in a decrease in production over time.

NON-MAJORITY OWNERSHIP OF PROPERTIES

  As with many independent oil and gas companies, Alliance is not the majority
owner in all of its oil and gas properties.  The combined company will be the
operator for only a small portion of the properties it owns.  Therefore, it may
have no control over the timing or amount of capital expenditures associated
with these properties.  If Alliance is unable to fund its pro rata share of
capital expenditures, the company's interests in its properties may be reduced
or forfeited.  If Alliance's cash flow from operations is not sufficient to
satisfy its capital expenditure requirements, there can be no assurance that
additional debt or equity financing, asset sales or sales of partial interests
will be available to meet these requirements.

DEPENDENCE ON OTHER OPERATORS

                                       14
<PAGE>
 
  With respect to wells not operated by LaTex and Alliance in which they own a
working interest, the independent operators are, in some cases, privately-held
companies which may have limited financial resources.  If a third party operator
experiences financial difficulty and fails to pay for materials and services in
a timely manner, the wells operated by such third party operators could be
subject to material and workmen's liens.  In such event, the combined company
would occur costs in discharging such liens.

DEPENDENCE ON KEY PERSONNEL

  Alliance believes that the continued success of the combined company will
depend to a significant extent upon the abilities and continued efforts of its
Board of Directors and its senior management, particularly John A. Keenan, its
Managing Director.  The loss of the services from any of its key personnel could
have a material adverse effect on its results of operations.  Alliance
anticipates that it will obtain key-man insurance in the amount of $2,000,000
with respect to Mr. Keenan.  The success of Alliance will also depend, in part,
upon its ability to find, hire and retain additional key management personnel
who are also being sought by other businesses.  The inability to find, hire and
retain such personnel could have a material adverse effect upon Alliance's
results of operations.  See "Management--Directors and Executive Officers."

COMPETITION

  Alliance operates in a highly competitive environment.  It competes with major
integrated and independent energy companies for the acquisition of desirable oil
and natural gas properties, as well as for the equipment and labor required to
develop and operate such properties.  Many of these competitors have financial
and other resources substantially greater than those of the combined company.
See "Business and Properties--Competition."

GOVERNMENTAL AND ENVIRONMENTAL REGULATION

  The production of oil and natural gas is subject to regulation under a wide
range of international and United States federal and state statutes, rules,
orders and regulations.  In the United States, state and federal statutes and
regulations require permits for drilling, reworking and recompletion operations,
drilling bonds and reports concerning operations.  Most states in which the
combined company will own and operate properties have regulations governing
conservation matters, including provisions for the unitization or pooling of oil
and natural gas properties, the establishment of maximum rates of production
from oil and natural gas wells and the regulation of the spacing, plugging and
abandonment of wells. Many states also restrict production to the market demand
for oil and natural gas and several states have indicated interest in revising
applicable regulations in light of the persistent oversupply and low prices for
oil and natural gas production. These regulations may limit the rate at which
oil and natural gas could otherwise be produced from properties. Some states
have also enacted statutes prescribing ceiling prices for natural gas sold
within the state.

  Various federal, state and local laws and regulations relating to the
protection of the environment may affect Alliance's operations and costs.  In
particular, Alliance's production operations, its salt water disposal operations
and its use of facilities for treating, processing or otherwise handling
hydrocarbons and wastes therefrom are subject to stringent environmental
regulation.  Although

                                       15
<PAGE>
 
compliance with these regulations increases the cost of operations, such
compliance has not had a material effect on Alliance's capital expenditures,
earnings or competitive position.  Environmental regulations have historically
been subject to frequent change by regulatory authorities and Alliance is unable
to predict the ongoing cost of complying with these laws and regulations or the
future impact of such regulations on its operations. Alliance's general
liability coverage of $3,000,000 applies to certain, but not all, environmental
liabilities. A significant discharge of hydrocarbons into the environment could,
to the extent such event is not insured, subject Alliance to substantial
expense.

NO DIVIDENDS

  Neither Alliance nor LaTex has paid any dividends on its outstanding ordinary
or common shares, nor does Alliance intend to do so in the foreseeable future.
In addition, Alliance is precluded from paying dividends until such time as its
retained loss is cleared and will further be restricted from paying dividends
under the credit facility it will have with Bank of America after the Merger.
The combined company currently intends to retain its cash for the operation and
expansion of its business, including exploration, development and acquisition
activities. Accordingly, Alliance's ability to pay dividends will depend upon
such restrictions and the company's results of operations, financial condition,
capital requirements and other facts deemed relevant by the Board of Directors.

CREDIT FACILITY COVENANTS AND RESTRICTIONS

  LaTex currently owes approximately $19,385,496 under the LaTex Credit
Agreement with the Bank of America.  The interest rate on the indebtedness is,
at the option of LaTex, 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 (LIBOR) market.
The principal must be amortized at the rate of $322,500 per month with the
entire outstanding balance due March 31, 2000. The credit facility is secured by
first mortgages on all of LaTex's oil and gas properties.  The LaTex Credit
Agreement contains various affirmative and negative covenants including, among
others, the requirements that LaTex 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 that are not cured or waived could result
in a default under the LaTex Credit Agreement, in which case this indebtedness
would become immediately due and payable, and the lender could foreclose against
the collateral for the loan.  LaTex has been in default under various
affirmative and negative covenants of the LaTex Credit Agreement with respect to
which the Bank of America has agreed to not take any action before April 30,
1997.

  Alliance will enter into a Credit Agreement (the "Alliance Credit Agreement")
with the Bank of America at or before the time of Merger, amending and restating
the LaTex Credit Agreement in order to restructure LaTex's indebtedness to the
Bank.  The Alliance Credit Agreement will become effective on the date of the
Merger.  The terms of the Alliance Credit Agreement are similar to those of the
LaTex Credit Agreement, except that principal payments will be suspended until
October 31, 1998 following completion of the Merger.  This suspension of
payments will not include cash flows generated by the combined company that are
in excess of those agreed between the Bank and Alliance.  Alliance believes that
it will be in compliance with all representations and covenants under

                                       16
<PAGE>
 
the Alliance Credit Agreement at the date of the Merger and anticipates that it
will be able to remain in compliance with those covenants after that date.

TRADING MARKETS

  The LaTex Common Stock is presently quoted on Nasdaq.  Until September 4,
1996, the LaTex Common Stock was also listed on the Pacific Stock Exchange at
which time it was delisted due to a lack of adequate trading volume. Based on
their knowledge of the prices and volumes of trading of small independent oil
and gas companies on the London Stock Exchange, as reflected in the analysis of
Wood Roberts, Alliance and LaTex believe that the trading market for small
independent oil and gas companies is generally more favorable in London than in
the U.S.  At this time, Alliance is applying for listing on the London Stock
Exchange of the New Alliance Shares to be issued to LaTex shareholders in the
Merger. See "The Merger-Opinion of LaTex's Financial Advisor." Of course, there
is no assurance that the trading market for New Alliance Shares on the London
Stock Exchange will be more favorable than the current market for LaTex Common
Stock in the U.S. Alliance does not intend to list the New Alliance Shares on
any U.S. stock exchange or Nasdaq. Quotations for shares listed on the London
Stock Exchange are not generally readily available in newspapers or other
publications in the United States, but are available in the daily U.S. edition
of the Financial Times. However, investors may place orders for the purchase or
sale of shares traded on the London Stock Exchange through most licensed broker
dealers in the United States. 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 New Alliance Shares to be received in the Merger. Under current U.K.
law, the transfer of New Alliance Shares will generally give rise to a liability
to U.K. stamp duty, normally at the rate of 50p for every (Pounds)100 (or part
thereof) of the actual consideration paid.

ENFORCEABILITY OF THE U.S. SECURITIES LAWS

  Alliance is organized under the laws of England.  Six of its ten directors
after completion of the Merger are not subject to the jurisdiction of the U.S.
because they are neither citizens nor residents of the U.S.  Alliance has been
advised by its English solicitors that there is doubt as to the enforceability
in the U.K. against Alliance or any of its subsidiaries or any of their
respective directors, controlling persons or executive officers or any of the
experts named in this Proxy Statement in actions for enforcement of judgments of
U.S. courts of liabilities predicated upon, or in original actions predicated
solely upon, U.S. federal or state securities laws.  Nevertheless, Alliance has
irrevocably agreed that, after the Merger is completed, it may be served with
process with respect to actions based on the offer and sale of the New Alliance
Shares made by this Proxy Statement by serving Alliance at its principal U.S.
operations office: Attention:  President, 4200 East Skelly Drive, Suite 1000,
Tulsa, Oklahoma 74135.


                                   THE MERGER

INTRODUCTION

  At the Special Meeting, the shareholders of LaTex will consider and take
action with respect to the Merger Agreement pursuant to which Alliance Resources
(Delaware) Inc., a wholly owned subsidiary of Alliance, will be merged with and
into LaTex.  As a result of the Merger, each outstanding LaTex Share (other than
LaTex Shares, if any, held by LaTex in treasury and LaTex Shares held by a
shareholder who has properly exercised his dissent and appraisal rights) will
automatically be canceled and LaTex shareholders will receive New Alliance
Shares at the Conversion Rate.  The Board of Directors of LaTex has unanimously
approved the Merger Agreement as being in the best interests of LaTex and its
shareholders and directed that the Merger Agreement be submitted to LaTex's
shareholders for approval.

BACKGROUND OF THE MERGER

  Upon completion by LaTex of the acquisition of Germany Oil Company in April
1995, management of LaTex engaged the investment banking firm of Rauscher,
Pierce & Clark ("RP&C") for the purpose of assisting LaTex in seeking new equity
or convertible debt financing.  Management's view was that additional financing
was necessary to provide new growth opportunities through acquisitions and
further development of its oil and gas properties.  During the summer of 1995,
RP&C reviewed oil and gas reserve and cash flow information provided by LaTex.
During meetings conducted in Tulsa, Oklahoma in September, LaTex management
concluded that any efforts to raise convertible debt financing through RP&C's
efforts in Europe were possible only at a conversion price of $0.35 - 0.50 per
share of LaTex Common Stock, which would have been significantly dilative to
LaTex shareholders.  LaTex's management therefore decided not to seek additional
funds through a convertible debt offering.

  Following this conclusion, LaTex management determined that additional
financing might be available through a combination of LaTex and another oil and
gas company, and LaTex, through RP&C, initiated merger discussions with Harken
Energy Inc.  Although Harken and LaTex discussed

                                       18
<PAGE>
 
a combination of the two companies, the discussions did not result in either a
letter of intent or definitive merger agreement.  Discussions with Harken
terminated in March 1996. LaTex representatives also met with Tautest, Inc. in
November 1995, Call, Inc. in December 1995 and coho Resources in February 1996
to discuss possible business combinations or equity infusions.  All of these
discussions were unsuccessful.

  The hedging arrangement between LaTex and Bank of America had the effect of
reducing LaTex'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 this hedging arrangement was anticipated
to result in additional losses of $3,649,287 based on the then prevailing
commodity prices and interest rate. As a result of the negative impact on cash
flow of LaTex's hedge arrangement with the bank, and the bank's requirement that
substantially all of the proceeds from the sale of non-strategic properties be
applied to prepay borrowing, management became convinced that under the likely
future oil and gas price environment, substantial equity or new financing was
required to stabilize LaTex's deteriorating financial condition.

  Therefore, while continuing its policy to package and sell non-strategic oil
and gas properties and attempting to obtain approval of its principal bank for
the use of a portion of the sale proceeds for working capital, management of
LaTex continued to seek both merger partners and/or debt financing.  LaTex met
with and provided information to the Strategic Group of Miami, Florida in an
effort to obtain either supplemental financing or a re-financing of its bank
debt. Strategica submitted a written proposal in April 1996 to loan LaTex $2-3
million for development activities in exchange for certain collateral
guarantees, a financial advisor retainer fee and stock and warrants that would
ultimately comprise some 20-30% of the equity of LaTex. As a result of the
dilutive nature of this offer and due to the discussions having been initiated
on March 17, 1996, with Alliance, as discussed below, management rejected the
Strategica offer.

  During early April 1996, LaTex, through RP&C, met with National Energy Group
at their offices in Dallas, Texas.  These discussions did not result in any
further action by either party.  In late June 1996, LaTex received an
unsolicited inquiry from Gothic Energy of Tulsa, Oklahoma.  Gothic subsequently
made a written offer to exchange shares of its common and preferred stock with
LaTex's shareholders such that the consideration to be received by LaTex's
shareholders would have approximated the then current $0.35 market price of
LaTex Common Stock, payable in Gothic stock.  The Gothic offer was rejected by
management as significantly deficient to the offer from Alliance which had, in
the meantime, been accepted by LaTex's Board.  The Gothic offer was considered
deficient primarily because it was based on the current stock market values of
Gothic and LaTex as opposed to the proposed Alliance transaction which was based
on net asset values of the two companies, which imputed a higher value to LaTex
than did the Gothic offer. No further discussions with Gothic resulted.

  In its effort to refinance its senior debt in light of the proposed merger
with Alliance, LaTex's management through Wood Roberts held discussions with
Midland Bank Plc and Union Bank of California during the period from August to
October 1996. Neither initiative resulted in a financing proposal.

                                       19

  John A. Keenan, the chief executive of Alliance, is an attorney who has been
involved in oil and gas transactions and has been an officer of oil and gas
companies in Houston for several years. John Martinson, a director of LaTex, is
also located in Houston and has been involved in numerous transactions with oil
and gas companies. Messrs. Keenan and Martinson have had a business acquaintance
for several years. In February 1996, they had a telephone discussion regarding
Mr. Keenan's recent involvement with Alliance, prior to his appointment as the
chief executive, as an advisor and non-executive director. The telephone
conversation consisted mainly of Mr. Keenan's description of the state of
Alliance's operations and the acquisition strategy that the company had adopted.
Mr. Martinson then indicated that LaTex might be interested in a potential
combination with Alliance.

  Several phone conversations between Messrs. Keenan and Martinson ensued
regarding a potential combination between Alliance and LaTex which resulted in a
meeting between the two men on March 11, 1996.  At the meeting, Mr. Keenan gave
Mr. Martinson an update on Alliance, including some discussion of Alliance's
current activities, potential ventures in the former Soviet Union as well as
background on Alliance's largest shareholder, Trans Arabian Energy Limited
("Trans Arabian").  Both men agreed to engage in further discussions after
briefing management at their respective companies.

  On March 12, 1996, LaTex held a board of directors meeting at which the
possibility of a merger with Alliance was discussed and in which the LaTex Board
noted that a merger with Alliance could enhance the ability of the combined
company to raise equity capital. At this meeting the LaTex board authorized
management to discuss with representatives of Alliance a possible merger of the
two companies. This was followed by a meeting in Houston on March 17, 1996 by
and among Mr. Keenan, Mr. Martinson and Jeffrey T. Wilson, the Chairman and CEO
of LaTex. The meeting was general in nature and included discussions of both
companies and the relative merits of a combination. Mr. Wilson indicated LaTex's
concern that a combined company retain key employees of LaTex, other than
Messrs. Wilson and Henley. Mr. Keenan related that he would discuss a potential
combination with Rothschild Natural Resources, L.L.C. ("Rothschild"), financial
advisers to Alliance, and Messrs. Martinson and Wilson agreed to discuss same
with Bank of America, LaTex's principal lender.

  Subsequent discussions with those parties elicited positive responses, which
led to a meeting in LaTex's offices in Tulsa, Oklahoma on April 9, 1996, where
Mr. Keenan met with the members of LaTex Board of Directors and senior
management. At this meeting, the parties discussed a number of issues that would
need to be resolved in connection with a combination, including a disposition of
LaTex's interests in Wexford Technology, Inc. ("Wexford") and Imperial
Petroleum, Inc. ("Imperial") as well as its international operations, the fair
treatment for holders of LaTex's two classes of preferred stock and warrants,
the required approval by the Bank of America, and the future role of Mr. Wilson
as a consultant to the combined company. Mr. Keenan stated that as a condition
to any transaction, Alliance would require the disposition of both Wexford and
Imperial in order to allow the combined company to focus its efforts and
available resources on its core oil and gas business. In addition, the parties
discussed their mutual preference that the common stock of the combined company
be traded on the London Stock Exchange rather than Nasdaq and their desire that
LaTex's non-strategic properties be sold before the merger if possible.

                                       20
<PAGE>
 
  On April 23, 1996, a conference call involving Messrs. Keenan, Martinson and
Wilson led to the creation of a list of the key issues discussed in the April 9
meeting being agreed.  At this time, LaTex drafted a letter of intent which was
circulated internally for discussion purposes.

  Mr. Martinson met Mr. Keenan and Mr. Christopher Samuelson, a non-executive
director of Alliance, on April 26, 1996, to discuss the potential merger of
LaTex and Alliance.  Mr. Samuelson discussed potential international
opportunities that might be available to the combined companies after a merger
and indicated a desire to proceed with discussions.  By a memorandum dated May
1, 1996, Mr. Martinson recommended a merger with Alliance to fellow board
members of LaTex.

  On May 6th, Mr. Martinson held separate discussions with Mr. Keenan and Mr.
Wilson concerning the merger, which culminated in Mr. Wilson agreeing to provide
Alliance with a copy of the Lee Keeling oil and gas reserve analysis prepared
for LaTex and a decision by Messrs. Wilson and Martinson and Mr. Philip Wade, an
outside director and significant shareholder of LaTex, to travel to London the
week of May 22, 1996, to discuss the potential merger between Alliance and LaTex
and to meet members of Alliance's board.  On May 13, 1996, Messrs. Martinson and
Keenan met in Houston to review the status of the discussions.  At the meeting,
Mr. Keenan indicated that he was to be named as Managing Director of Alliance
and discussed Alliance's future business strategy.  This meeting led to the
Board of LaTex agreeing to allow Mr. Wilson to enter into formal discussions
with Alliance regarding a merger of the two companies.

  Prior to arrival in London, Mr. Keenan held telephone conversations with Mr.
Wilson and Mr. Martinson and Mr. Keenan agreed to supply to LaTex a copy of
Alliance's oil and gas reserve analysis. A list of discussion items was also
agreed, as well as an agenda.  On May 22nd, Messrs. Wilson, Martinson and Wade
met in London with representatives of Alliance to discuss the method of the
merger, advisors, regulatory requirements and general structuring.

  Meetings were held all day on May 23rd, at which the participants discussed
the value of each company and the relative portion of the combined company that
should be held by each group of shareholders. The participants also discussed
various United Kingdom brokers who might act as sponsors of the transaction in
the United Kingdom, the need for Alliance to effect a reverse split of its
shares, and the disposition of LaTex's interests in Wexford and Imperial as well
as its international operations. The parties agreed to hold further meetings
with their respective Boards of Directors to explore the discussions and agreed
that Mr. Keenan and Mr. Wilson would determine the next steps, if any.

  On June 3rd, the members of the LaTex Board of Directors discussed the
transaction by telephone. In particular, the Board reviewed the matters
discussed at the recent meetings in London and discussed the strategic reasons
for the merger, the future plans of Alliance, including possible future
acquisitions, none of which were seriously pursued, Alliance's management, the
potential value of the combined company and the new proposal of Alliance that
Holders of LaTex shares would receive 72% of the shares of the combined company
and the holders of Alliance shares would retain the balance of 28% of the shares
of the combined company. This meeting led to the transmittal of a letter of
intent from LaTex to Alliance on June 4th. The LaTex Board of Directors also
discussed the continued engagement of Wood Roberts as its financial advisor in
connection with the discussions and any transaction. On June 6th, Mr. Martinson
and Mr. Keenan met in London to

                                       21
<PAGE>
 
discuss the letter of intent. Further discussions among the parties took place
over the next week leading to a meeting on June 17, 1996 in London among Messrs.
Martinson, Keenan and Mr. Michael Humphries of Rothschild. All facets of the
proposed merger were discussed, including the management of the combined
company, updates of the financial condition of both parties, and the oil and gas
reserves of both parties. Mr. Wilson was briefed by Mr. Martinson following the
meeting.

  Various meetings in London followed over the next week concerning the details
of the proposed merger which led to a revised draft letter of intent from LaTex
to Alliance dated June 24, 1996.  On June 25th, Alliance forwarded a revised
form of a draft letter of intent to LaTex which led to further discussions by
the parties.  A revised letter of intent dated June 28, 1996, was executed by
both parties.

  During July, both companies conducted due diligence, Williams de Broe
indicated that it would continue as Alliance's broker, Alliance delivered an
initial draft of the Merger Agreement to LaTex, LaTex undertook a review of the
legal and tax implications of the Merger, and the parties engaged in
negotiations concerning the definitive merger agreement.  On July 31, 1996, the
Board of Directors of LaTex met to review the status of the merger discussions,
review and approve the sale of assets excluded from the Merger and request a
fairness opinion from Wood Roberts.  This culminated with a meeting of the LaTex
Board of Directors on August 9, 1996, at which time, after receiving a report
from Wood Roberts concerning the fairness of the Merger from a financial point
of view to the shareholders of LaTex (included in Appendix C), the LaTex board
unanimously resolved to accept the Merger Agreement as previously negotiated. On
August 12, 1996, the parties executed the Merger Agreement.

  As originally executed, the Merger Agreement provided that certain actions
were to take place before September 15, 1996.  On September 16, 1996, both
companies executed a letter agreement providing that those actions could take
place at any time before September 27, 1996.  The Merger Agreement also
contained a condition to closing that Alliance deliver to LaTex an opinion of
counsel that the Merger would not result in the shareholders of LaTex
recognizing taxable  income or loss as a result of the Merger.  If Alliance were
to be unable to deliver such an opinion, it could elect at its option to
restructure the Merger so that LaTex would be the surviving entity and the
existing shareholders of Alliance would receive shares of LaTex Common Stock in
exchange for the Existing Alliance Shares in an amount that would result in the
same percentage ownership of the resulting entity as in the Merger. After
execution of the Merger Agreement, Alliance determined that it would in fact not
be able to deliver the indicated tax opinion.  In addition, after further
discussions, the Boards of Directors of both parties concluded that, in the
opinion of each, the New Alliance Shares to be issued in the Merger would be
likely to trade at a more attractive price on the London Stock Exchange than on
a U.S. market and that the shares of a U.K. public limited company would be
likely to trade at a more attractive price on the London Stock Exchange than the
shares of a U.S. corporation.  Therefore, the parties agreed to amend the Merger
Agreement to eliminate the condition regarding the delivery of the tax opinion.
This amendment was executed effective September 27, 1996.

  As originally approved by the LaTex Board of Directors, the Merger Agreement
provided that the New Alliance Shares would be allocated to the LaTex Series A
Stock and the Series B Stock on the basis of the number of shares of LaTex
Common Stock into which the LaTex Series A Stock and

                                       22
<PAGE>
 
LaTex Series B Stock are convertible. Each share of LaTex Series A Stock is
convertible into  approximately three shares of LaTex Common Stock and each
share of LaTex Series B Stock is convertible into approximately 6.67 shares of
LaTex Common  Stock.

  By the terms of the LaTex Series A Stock and the LaTex Series B Stock,  LaTex
is permitted, under certain circumstances, to pay accrued dividends on  those
shares in additional shares of the same series rather than in cash.   Effective
December 31, 1996, and again effective March 31, 1997, the LaTex Board of
Directors determined to pay the dividends in kind.  Because the negotiations
with Alliance had resulted in the agreement that the shareholders of LaTex, as a
whole, would hold 72% of the outstanding shares of the combined company and the
shareholders of Alliance would hold 28% of the outstanding shares of the
combined company, the payment of dividends in kind did not increase the total
number of New Alliance Shares to be issued in the Merger, but increased the
number of New Alliance Shares that would be issued to the holders of the LaTex
Series A Stock and LaTex Series B Stock, and correspondingly decreased the
number of New Alliance Shares to be issued to the holders of the LaTex Common
Stock.

  In January 1997, Enron Reserve Acquisition Corp. ("Enron"), which owns all  of
the LaTex Series B Stock, notified LaTex that it did not believe the  allocation
of New Alliance Shares between the LaTex Common Stock and the LaTex  Series B
Stock was appropriate.

  On February 4, 1997, representatives of Enron, LaTex and Alliance met to
discuss the allocation. On February 6, 1997, the Board of Directors of LaTex met
to discuss the allocation issues and requested Wood Roberts to advise it whether
the allocation was appropriate. On February 17, 1997, Wood Roberts advised the
LaTex Board of Directors that, in Wood Roberts' view, the allocation should be
adjusted so that the holders of the LaTex Series B Stock would receive a greater
portion of the New Alliance Shares.

  On March 7 and March 10, 1997, Jeffrey T. Wilson and representatives of Enron
had further discussions, as a result of which Mr. Wilson recommended to the
LaTex Board of Directors that the allocation be adjusted so that each share of
LaTex Series B Stock would be allocated the same number of New Alliance Shares
as would be allocated to approximately 7.18 shares of LaTex Common Stock.
Because this allocation was not contemplated in the Merger Agreement, Mr.
Wilson's recommendation required an amendment of the Merger Agreement.

  Also during January and February, 1997, representatives of Alliance discussed
with Bank of America NT & SA the possibility that the Bank would accept New
Alliance Shares as payment for the $200,000 fee previously agreed to be paid to
the Bank upon the assumption by Alliance of the LaTex Credit Agreement and in
consideration for the transfer to Alliance of an overriding royalty interest
(the "ORRI") held by the Bank that burdened certain of LaTex's oil and gas
properties. On February 19, 1997, Alliance and the Bank agreed in principle that
the Bank would receive 156,250 New Alliance Shares in payment of the $200,000
fee and, in exchange for the ORRI, would receive additional New Alliance Shares
or their equivalent amounting to approximately 2,421,875 shares of outstanding
stock of Alliance and warrants exercisable for additional shares amounting to
approximately 1,210,938 New Alliance Shares at a price of (Pounds)1.00 per
share.  Because the issuance of New Alliance Shares and warrants to the Bank was
not contemplated in the Merger Agreement, particularly in the agreement of the
parties that ownership of the combined company would be

                                       23
<PAGE>
 
divided 73% to the former LaTex Shareholders and 27% to the holders of Existing
Alliance Shares, the agreement in principle with the Bank required an amendment
to the Merger Agreement.

  On March 12, 1997, the LaTex Board of Directors met to consider the various
matters that required amendments to the Merger Agreement.  At this meeting, the
Board of Directors of LaTex received an opinion of Wood Roberts concluding that
the financial terms of the Merger are fair to the holders of each class of LaTex
Shares.  This opinion is included in Appendix C.  After discussion, the LaTex
Board of Directors unanimously approved an amendment to the Merger Agreement
revising the allocation of New Alliance Shares to be as reflected in this Proxy
Statement and extending the date after which the Merger Agreement may be
terminated by either party to April 30, 1997.

REASONS FOR THE MERGER

  In considering the merits of a potential merger with Alliance, the LaTex Board
of Directors considered a number of factors and issues, including: (1) the
financial condition of both LaTex and Alliance; (2) the strategic aspects of a
merger with Alliance; (3) management's unsuccessful attempts to secure
additional debt and or equity financing; (4) management's prior discussions with
other potential merger candidates; (5) the stock market implications to LaTex
shareholders; (6) the tax consequences to LaTex shareholders; (7) the social
issues with respect to LaTex's management and staff and (8) the relationship
between Alliance and its principal shareholder.

  In considering the financial condition of Alliance and its suitability as a
merger partner, it was important to LaTex management to determine the level of
financing or cash that would be available to LaTex following a merger.   LaTex
evaluated the oil and gas assets of Alliance, including computations of future
cash flow, reviewed the public filings of Alliance to determine its working
capital position and assessed the likely impact of Alliance's legal action
against its former chief executive.  Based on its internal evaluation, LaTex
determined that as a result of Alliance's negotiations with LaTex's senior
lender, the combined company will have sufficient additional borrowing capacity
in conjunction with abatement of principal payments until July 31, 1998 and cash
to stabilize the financial condition of the combined company.  LaTex management
determined that Alliance's properties would likely be able to support additional
debt or equity financing in excess of $3 million and most likely in the $5
million range.  In addition, LaTex determined that Alliance's actions against
its former chief executive would require resolution prior to the execution of a
merger agreement between the companies.

  The ability of LaTex to execute its strategy of acquiring additional oil and
gas assets had been hampered as a result of its financial condition and
limitations in the LaTex Credit Agreement.  Based on LaTex's review of Alliance
and the improved financial condition of LaTex after the Merger, which would
allow refinancing of its senior debt, the Board of Directors of LaTex viewed the
potential Merger with Alliance as a strategic step to allow LaTex to become
active again in the acquisition and exploitation of oil and gas properties.
Additionally, because of LaTex's historical attempts to access and participate
in significant international ventures and because of Alliance's intentions to
pursue such ventures, the Board of Directors of LaTex deemed the overall
strategies of the companies to be consistent.

                                       24

  Because the share price of LaTex's Common Stock remained around $0.40 per
share and as a result of the terms of the proposed merger with Alliance whereby
the common shareholders would receive between .8 and .9 of a share of Alliance
which, after giving effect to its reverse split, was trading on the London Stock
Market at $1.24 per share, the Board viewed the exchange of shares with Alliance
as likely to result in an increase in the share value of the combined  company.

  While the LaTex Board acknowledged the potential for an increased cost to its
shareholders and a likelihood that initially certain of its shareholders may
find it more difficult to both follow and trade the combined company's stock on
the London Stock Exchange, the LaTex Board deemed the possibility of a
significant share price increase and the financial and strategic benefits of the
Merger as more important. Of equal importance to the Board was the consideration
of market support for the combined company after completion of the Merger.

  Initially, the LaTex Board had included as a condition of the Merger that the
transaction be tax-free to LaTex's shareholders.  However, after it became
apparent that Alliance would be unable to accomplish a tax-free structure in the
time available, the LaTex Board re-evaluated its position.  After reviewing the
tax implications of the Merger and discussions with its own advisors, the LaTex
Board determined that the taxable nature of the transaction would likely affect
two groups of its shareholders most: (i) insiders and (ii) shareholders who have
purchased the stock at its present price.  Although the preferred position of
the Board was to effect a tax-free transaction, it was determined that the
personal tax considerations of these groups of shareholders could not be known
with certainty, and that the financial and strategic considerations for LaTex
were significant enough to proceed with the Merger under a taxable structure.

  Because Trans Arabian had recently acquired a significant position in Alliance
and had obtained two of eight board seats, management of LaTex investigated the
potential motives and ramifications of Trans Arabian's involvement.  Alliance
had suggested that in the future it may consider acquiring assets from
corporations affiliated with Trans Arabian. LaTex's major concern was to ensure
that any future transactions with related parties would occur for value and in a
manner deemed appropriate. After reviewing the corporate governance requirements
for companies domiciled in the UK and, after discussions with members of the
Board of Alliance nominated by Trans Arabian, LaTex determined that these issues
could best be resolved by requiring equal representation on Alliance's Board
with the Trans Arabian group. As a result, LaTex included as a condition of the
Merger the expansion of the Alliance Board to ten members and the nomination of
Messrs. Wilson and Martinson to the Board of Alliance.

  As a result of the limited staff of Alliance, LaTex viewed Alliance as a
preferable merger partner when considering the livelihood of its employees.
LaTex's staff has been proficient at its core business through the years and the
Board deemed its preservation as an important benefit to the Merger and future
growth of LaTex.  In addition, Mr. Wilson agreed to enter into a consulting
agreement concurrent with the Merger to provide a minimum of six months of
transition and to assist the combined company in the acquisition of oil and gas
properties.

OPINION OF LATEX'S FINANCIAL ADVISOR

  Wood Roberts was engaged by LaTex to examine the terms of the proposed Merger
and to render an opinion as to the fairness of such terms from a financial
standpoint to the shareholders of LaTex.  On August 8, 1996, Wood Roberts
delivered its written opinion, along with related documentation, to the Board of
Directors of LaTex to the effect that the terms of the proposed Merger were fair
from a financial standpoint to the shareholders of LaTex.

  On September 30, 1996, LaTex asked Wood Roberts to examine the proposed
amendment to the terms of the Merger whereby the exchange of LaTex Shares and
warrants for Alliance shares and warrants ceased to be a tax-free
reorganization, and to render an opinion as to the fairness of such amendment
from a financial standpoint to the shareholders of LaTex.  On October 1, 1996,
Wood Roberts delivered its second written opinion, along with related
documentation, to the Board of Directors of LaTex to the effect that the amended
terms of the proposed Merger remained fair from a financial standpoint to the
shareholders of LaTex.

  On March 11, 1997 Wood Roberts delivered its third opinion to the effect  that
the allocation of New Alliance Shares among the three classes of LaTex  Shares
was fair to holders of each class.

  The text of the written opinions, which set forth the assumptions made,
matters considered, limitations to and scope of the review undertaken by Wood
Roberts in rendering its opinions are attached as Appendix C to this Proxy
Statement and are incorporated herein by reference.

  In arriving at its opinions, Wood Roberts reviewed the Merger Agreement and
the amendment thereto, information provided by the management of LaTex and
Alliance and by certain of their professional advisors, as well as information
in the public domain.  In addition, Wood Roberts met with the management of
LaTex and Alliance to discuss the historical and current business of each
company, their prospects as stand-alone entities and the potential short-term
and medium-term strategic and financial benefits of the proposed Merger.

  Wood Roberts' review of the terms of the Merger was undertaken with reference
to, among other things: the relative net asset value, financial condition and
debt ratios; earnings, cash flow and ability to develop or re-work assets of
both LaTex and Alliance; and the pro forma financial position of the merged
company and its ability to obtain debt or equity funding.  Wood Roberts analyzed
certain financial, industry and market-related information and data and examined
data indicative of the relative merits of LaTex shareholders exchanging their
shares for shares listed for trading on the London Stock Exchange.  Wood Roberts
was not asked to undertake an independent analysis of comparable transactions
but reviewed certain published data in this regard.

  In rendering its opinions, Wood Roberts did not independently verify any of
the foregoing information and, in using such information in its review of the
Merger, relied upon it being complete and accurate in all material respects.
Furthermore, Wood Roberts assumed that the appropriate regulatory and
governmental approvals to the Merger would be forthcoming and that no
restriction would be imposed that would have a material adverse effect on the
contemplated benefits of the Merger. Wood Roberts was not asked to examine in
detail the terms of the disposal of certain assets of LaTex.

                                       26
<PAGE>
 
  Wood Roberts rendered its opinions on the basis of its knowledge of the
circumstances disclosed to it as of the date of the opinions.

  Analysis of Exchange Ratio (Relative Contribution Analysis).  Wood Roberts
performed a relative contribution analysis to examine the relationship between
the percentage ownership of the combined company that the shareholders of LaTex
and the shareholders of Alliance would have following the Merger. In making this
analysis, Wood Roberts considered (i) the percentage of the merged company's
outstanding stock that the shareholders of each of LaTex and Alliance would hold
following the Merger, (ii) the relative reserve values of each company, adjusted
by Wood Roberts to the extent it deemed appropriate, and (iii) the net asset
value of each company, taking into account bank debt and payables.  Based on
this analysis, Wood Roberts calculated that LaTex was contributing 71.67% of the
pro forma assets of the combined company. Under the terms of the Merger, LaTex
shareholders will receive 73% of the stock in the combined company, without
taking into account the New Alliance Shares and Bank Warrants to be issued to
the Bank or the ORRI to be acquired from the Bank.

  Comparable Public Company Analysis in Relation to Valuation on the London
Stock Exchange. Wood Roberts also compared certain financial results and assets
of LaTex, Alliance and selected companies whose shares are traded on the London
Stock Exchange and that LaTex and Wood Roberts deemed to possess certain
characteristics similar to those the combined company would have (the
"Comparable Public Companies").  The Comparable Public Companies selected by
LaTex included Great Western Resources Inc., Aminex PLC, Aviva Petroleum Inc.,
Dominion Energy PLC, Tuskar Resources PLC and United Energy PLC.

  The primary purpose of this analysis was to assess the public market
valuations of the Comparable Public Companies on the London Stock Exchange
relative to the current public market valuation of LaTex on Nasdaq and, on the
same basis, to estimate an indicated value for the shares of the combined
company. The two primary ratios used in this comparison were net assets and cash
flow relative to share price.  Based on this analysis, Wood Roberts calculated
an approximate indicated value of the shares of the combined company on the
London Stock Exchange of $1.11 to $1.22 per share, compared to a pro forma net
asset value calculated by Wood Roberts of approximately $1.41 per share.  Wood
Roberts stated that such indicated value is not a forecasting tool as the actual
price at which the shares will trade will depend upon many factors.

  Other Matters.  Certain other matters were considered by Wood Roberts in
rendering its opinion that the terms of the Merger were fair to the shareholders
of LaTex.  These additional matters included, but were not limited to, the
determination by Wood Roberts that it was more likely than not:

     (i)    That the Merger would improve the ability of the combined company to
refinance the current LaTex bank debt and payables because Alliance has no debt
and has a positive working capital balance; LaTex has significant debt and
working capital deficit; the Merger reduces the debt ratio (liabilities/assets)
from 44% to a more manageable 35%; Wood Roberts had proposed to other banks that
they refinance LaTex's debt, but the banks declined to do so; and Bank of
America will not refinance LaTex's debt in the absence of the Merger;

                                       27
<PAGE>
 
     (ii)   That the liquidity of and market for the shares of the combined
company on the London Stock Exchange would be greater than the current market
for LaTex shares because the combined company will have the support of a major
merchant bank, its U.S. natural resource subsidiary and a good quality
stockbroker, the involvement of which should be expected to have the effect of
causing institutional investors in the U.K. and the U.S. to consider the
combined company as a potential investment, to offer the likelihood of placing
larger blocks of shares with such institutional investors, to provide investor
research coverage and to have the overall effect of increasing international and
private investor awareness and, currently, LaTex does not have any such
support;

     (iii)  That, in the absence of the Merger, LaTex would be unable to raise
new equity capital without significant dilution to the LaTex shareholders at a
price that reflects the asset value of LaTex because the price of LaTex Common
Stock is at an all-time low; LaTex has a weak balance sheet; LaTex is in default
in its loan obligations to Bank of America, to its suppliers and to its royalty
owners; and consequently, in such a situation it is unlikely that new equity
could be raised at anywhere near the estimated net asset value per share of
$1.41.  In comparison, by Alliance merging with LaTex, Alliance is in effect
providing new equity at a price estimated to be the equivalent of $1.43 per
share;

     (iv)   That the management would be stronger as a result of the Merger
because the management of Alliance brings broad domestic and international
experience in technical, financial and corporate management and the managing
director has extensive experience working with lending banks; and

     (v)    That the Merger would increase the ability of the LaTex shareholders
to benefit from growth by acquisition because in its current financial state
LaTex was unlikely to be able to issue shares for an acquisition at a price that
would be acceptable to the owners of the target company without diluting the
current shareholders significantly; a potential target company is expected to be
more likely to agree to be acquired by the combined company, with its lower debt
ratio and stronger management, than by LaTex; and LaTex is expected to be unable
to take on more debt in view of its financial position and its default with Bank
of America.

  Wood Roberts did not weight or quantify their consideration of these factors,
but viewed all of them as contributing to their opinion.

  There is no assurance that any of the results anticipated in the Wood Roberts
analysis will actually occur.  These determinations were made by Wood Roberts
solely for the purpose of analyzing the financial terms of the  Merger.

  The summary set forth above is not a complete description of Wood Roberts'
analysis of the terms of the Merger or consideration of the fairness of such
terms to the shareholders of LaTex. Such analysis included the consideration of
many factors and assumptions with respect to the energy industry as a whole,
general business and economic conditions, the subjective market valuations
placed on the stock of companies traded on the London Stock Exchange and other
matters, many of which are or may be beyond the control of the combined company
and its management.

  Estimates made by Wood Roberts in its opinions are not necessarily indicative
of actual values and share prices imputed by the analysis performed by Wood
Roberts may not necessarily reflect the actual price placed upon the shares of
the merged company.  As such analysis and estimates are inherently subject to
uncertainty, none of Wood Roberts, LaTex or Alliance assume responsibility for
their accuracy.

  Wood Roberts is an investment banking firm and as part of its investment
banking business is regularly engaged in the valuation of businesses and
securities in connection with mergers, acquisitions and other corporate
relationships.   LaTex selected Wood Roberts to render a fairness opinion in
connection with the Merger because of Wood Roberts' expertise in the oil and gas
industry and its experience in transactions similar to the Merger, as well as
Wood Roberts' prior relationship and familiarity with LaTex.  From time to time,
since August 1994, Wood Roberts has provided investment banking services to
LaTex and has acted as financial adviser in matters unrelated to the Merger.
Wood Roberts has received customary compensation for such services. As
compensation for initiating the Merger, rendering the fairness opinions and
other services in connection with the Merger, LaTex has agreed to pay Wood
Roberts a fee of $240,000. LaTex has also agreed to reimburse Wood Roberts for
its reasonable expenses in relation to its services and to indemnify Wood
Roberts for any liability arising from its engagement as financial advisor to
LaTex. LaTex has also agreed to pay Wood Roberts a fee of 100,000 shares of
LaTex Common Stock upon the successful restructuring of the LaTex Credit
Agreement. Because the LaTex Credit Agreement will be restructured in connection
with the Merger, Wood Roberts will receive 85,981 New Alliance Shares in payment
of this fee upon completion of the Merger. In addition, Wood Roberts and its
affiliates hold warrants to purchase 756,000 shares of LaTex Common Stock at
exercise prices of $0.75 to $1.20 per share.

  John R. Martinson, a director of LaTex, is a principal of Wood Roberts and
will be a director of Alliance after the Merger.  Mr. Martinson recused himself
from consideration of the terms of the Merger for the purpose of the fairness
opinions.

 TERMS OF THE MERGER

  General.  The detailed terms and conditions of the Merger are contained or
described in the Merger Agreement, which is included in this Proxy Statement as
Appendix B.  The Merger Agreement sets forth the representations and warranties
of the parties, certain agreements between the parties pending the Merger, the
conditions precedent to the Merger, the terms of the Merger, the method of
effecting the Merger, the manner of converting LaTex Shares into New Alliance
Shares and certain other provisions. The statements made in this Proxy Statement
with respect to the terms of the Merger are qualified in their entirety by, and
made subject to, the more complete information contained in the Merger
Agreement.

  The Merger Agreement was entered into between LaTex and Alliance on August 12,
1996. Pursuant to the terms of the Merger Agreement, LaTex will acquire Alliance
through the merger of Alliance into LaTex.

                                       29
<PAGE>
 
  The Merger.   Under the DGCL, the affirmative vote of the holders of a
majority of the outstanding shares of LaTex's Common Stock is required to
approve and adopt the Merger Agreement.

  The Merger is also subject to certain conditions, some of which are beyond the
control of any of the parties to the Merger Agreement.  See "Conditions to the
Merger."  Consequently, there can be no assurance that the Merger will take
place, even though the Merger Agreement contains the agreement of each of the
parties thereto to use their best efforts to complete the Merger.

  Immediately after approval and adoption of the Merger Agreement by the
requisite votes of LaTex's and Alliance's shareholders and the satisfaction or
waiver of the conditions to the Merger described below, the parties will conduct
a closing for purposes of executing and delivering such documents and
certificates as may be required under the Merger Agreement (the date of such
closing being referred to hereinafter as the "Closing Date").  The Merger will
become effective upon the filing of a Certificate of Merger with the Secretary
of State of the State of Delaware (the "Effective Time of the Merger").  It is
presently contemplated that the Effective Time of the Merger will, subject to
the terms and conditions of the Merger Agreement, occur either the same day as
the Special Meeting or the following business day. At and after the Effective
Time of the Merger, the surviving company will be a wholly owned subsidiary of
Alliance.

  At the Effective Time of the Merger, by virtue of the Merger and without any
further action on the part of the holder thereof, each then outstanding LaTex
Share (other than LaTex Shares, if any, held by LaTex in treasury and shares
held by a shareholder who has properly exercised his dissent and appraisal
rights) will automatically be canceled and LaTex shareholders will receive New
Alliance Shares at the Conversion Rate.  Each LaTex Share held by LaTex in
treasury will be canceled.  No fractional New Alliance Shares will be issued in
connection with the Merger. Instead, the shares issued to each holder will be
rounded to the nearest whole number of New Alliance Shares. No cash will be paid
for fractional shares not received. The surrender of certificates representing
LaTex's stock for certificates representing New Alliance Shares will be effected
pursuant to documents that will be sent to shareholders as promptly as
practicable after the Effective Time of the Merger. See "Exchange of
Certificates."

  Conversion Rate. If the Merger Agreement is approved and the Merger is
completed, each holder of LaTex Shares will be entitled to receive the number of
New Alliance Shares determined by multiplying the number of LaTex Shares held by
the holder by the Conversion Rate. The Conversion Rate will be 0.85981 of a New
Alliance Share for each share of LaTex Common Stock, 2.58201 New Alliance Shares
for each share of LaTex Series A Stock, 6.17632 New Alliance Shares for each
share of LaTex Series B Stock and a New Warrant to subscribe 0.85981 of a New
Alliance Share for each share of LaTex Common Stock subject to warrants issued
by LaTex. Fractional New Alliance Shares will not be issued in the Merger.
Instead, the shares issued to each holder will be rounded to the nearest whole
number of New Alliance Shares. No cash will be paid for fractional shares not
received.

  Conduct of Business Prior to the Merger.  Both parties have agreed in the
Merger Agreement that, from the date of the Merger Agreement until the Effective
Time of the Merger, except as expressly contemplated by the Merger Agreement,
each will carry on business in the usual, regular 

                                       30
<PAGE>
 
and ordinary course in substantially the same manner as previously conducted and
use all reasonable efforts to (i) preserve intact its present business
organization, (ii) keep available the services of its present officers and key
employees, (iii) preserve its relationships with customers, suppliers and any
others having business dealings with them and (iv) comply with all laws
applicable to them and their respective properties, operations, business and
employees that if not complied with would result in a material adverse effect to
the party. In particular, the Merger Agreement provides that, prior to the
Effective Time of the Merger, unless consented to by the other party, neither
party will (a) engage in any of certain restricted acts set forth in the Merger
Agreement, (b) enter into any transaction other than in the ordinary course of
business or (c) amend its respective organizational or governing documents.

  Conditions to the Merger.  The obligation of LaTex to consummate the Merger

under policies of insurance maintained by or for the benefit of LaTex; (xi) no
material information or data provided or made available to Alliance by or on
behalf of LaTex shall be incorrect in any material respect; (xiii) LaTex shall

London Stock Exchange.

  Disposition of Certain Assets.  LaTex is required to dispose of its interests
in its unconsolidated affiliates Wexford and 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, LaTex 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 LaTex's investments in Tunisia and Kazakhstan,
respectively).  Effective July 31, 1994, LaTex wrote off its $22,918 investment
in Phoenix Metals.  LaTex has entered into a Purchase Agreement with Imperial
pursuant to which LaTex will sell its interests in Wexford, Imperial, LaTex
Resources International and Phoenix Metals to Imperial for 100,000 shares of
LaTex Common Stock.

  Termination.  Notwithstanding approval of the Merger by LaTex's shareholders,
the Merger Agreement may be terminated at any time prior to the Effective Time
of the Merger by the mutual written consent authorized by the Boards of
Directors of LaTex and Alliance.  In addition, the Merger Agreement may be
terminated by either party if the Merger is not completed by April 30, 1997.
The Merger Agreement may also be terminated by Alliance prior to the Effective
Time of the Merger if (i) any representation, warranty or covenant made in the
Merger Agreement for the benefit of Alliance is untrue in any material respect
and such breach is not cured within ten days of notice thereof; (ii) all of the
conditions to Alliance's obligation to complete the Merger shall not have been
satisfied or waived by Alliance prior to the Closing Date or (iii) completion of
the Merger would violate any nonappealable final order, decree or judgment of
any court or governmental body having competent jurisdiction.  The Merger
Agreement may be terminated by LaTex if (i) Alliance has materially breached the
representations and warranties contained in the Merger Agreement or has failed
to comply in any material respect with its covenants and agreements set forth in
the Merger Agreement and Alliance shall not have cured such breach or failure
within 10 business days of receipt of notice thereof from LaTex, (ii) all of the
conditions to LaTex's obligation to complete the 

                                       32
<PAGE>
 
Merger shall have not been satisfied or waived by LaTex prior to the Closing
Date or (iii) completion of the Merger would violate any nonappealable final
order, decree or judgment of any court or governmental body having competent
jurisdiction. If either party receives an unsolicited offer from another person
to enter into a merger, sale or similar transaction at a time when the party has
not breached the Merger Agreement and determines to accept the offer, the party
may terminate the Merger Agreement by paying the other party a termination fee
of $1,000,000 plus the other party's expenses. Similarly, if a party receives an
offer from another person to enter into a merger, sale or similar transaction
and the party accepts the offer or has knowingly breached the Merger Agreement,
then the other party may terminate the Merger Agreement and receive from the
first party a termination fee of $1,000,000 plus expenses.

  No Solicitation Covenants. LaTex and Alliance have entered into certain
mutual covenants and agreements in the Merger Agreement, including covenants
that provide that neither party will (and will cause each of the executive
officers, directors, employees, representatives or agents not to) directly or
indirectly solicit, initiate or knowingly encourage the initiation of inquiries
or proposals from, or provide any confidential information to, or enter into any
agreement with, any person or entity concerning any sale of their assets or
shares of capital stock or any merger, consolidation, business combination,
liquidation or similar transaction involving the respective company. However, if
either company receives an unsolicited offer from a third party that, in the
exercise of its fiduciary duty after consideration of advice from its legal and
financial advisors, the Board of Directors of the company determines is likely
to be more beneficial to its shareholders than the Merger, the respective Board
of Directors may respond to the offer, but will promptly communicate to the
other party to the Merger the terms of any proposal that it may receive in
respect of any such transaction and will keep the other party informed as to the
status of any actions, including negotiations or discussions.

EFFECTIVE TIME OF THE MERGER

  It is currently anticipated that if all conditions to the Merger are satisfied
or waived by that time, the Effective Time of the Merger will occur on either
the same day as the Special Meeting or the following business day.

EXCHANGE OF CERTIFICATES

  At and after the Effective Time of the Merger, no transfer of LaTex Shares
outstanding prior to the Effective Time of the Merger will be made on the stock
transfer books of LaTex. As soon as practicable after the Effective Time of the
Merger, a letter of transmittal (the "Letter of Transmittal") will be mailed to
all holders of record of the LaTex Shares at the close of business on the date
of the Effective Time of the Merger to be used by such holders in surrendering
to the transfer agent of Alliance (the "Transfer Agent") certificates that,
prior to the Merger, represented LaTex Shares. The Letter of Transmittal will
contain instructions concerning the surrender of such certificates. CERTIFICATES
FOR LATEX SHARES SHOULD NOT BE SURRENDERED UNTIL THE LETTER OF TRANSMITTAL IS
RECEIVED BY THE SHAREHOLDER.

  Following the surrender of certificates formerly representing LaTex Shares,
shareholders will receive in exchange therefor certificates representing the
whole number of New Alliance Shares to which the holder is entitled. After the
Effective Time of the Merger and until so surrendered, each 

                                       33
<PAGE>
 
certificate that prior to the Effective Time of the Merger represented
outstanding LaTex Shares shall be deemed for all corporate purposes to represent
and evidence ownership of the proportional number of New Alliance Shares, except
that no dividends or other distributions payable by Alliance will be paid with
respect to such certificates and no voting rights will accrue to the holders
thereof until surrendered. Such dividends and distributions, if any, will be
accumulated and, at the time of such surrender, all such unpaid dividends or
distributions will be paid, without interest. If a certificate for New Alliance
Shares is to be issued to a person other than the person in whose name the
certificates representing LaTex Shares is registered, it will be a condition of
exchange that the LaTex Shares certificate so surrendered be properly endorsed
or otherwise in proper form for transfer and that the person requesting the
exchange will pay any transfer or other taxes required by reason of the issuance
of the Alliance certificate to a person other than the registered holder of the
LaTex certificate surrendered or establish to the satisfaction of Alliance that
such tax has been paid or is not applicable. The Transfer Agent will issue
certificates representing New Alliance Shares attributable to any certificate
that has been lost or destroyed only upon receipt of satisfactory evidence of
ownership of the shares represented thereby and after appropriate
indemnification.

REGISTRATION AND RESALE

  Pursuant to the Registration Statement of which this Proxy Statement is a
part, Alliance has registered under the Securities Act of 1933, as amended, and
the rules and regulations thereunder (the "Act") the 21,448,787 New Alliance
Shares to be issued in the Merger, the New Warrants to be issued by Alliance in
the Merger to replace currently outstanding warrants issued by LaTex, the
1,927,908 New Alliance Shares issuable on exercise of the New Warrants, the
2,578,125 New Alliance Shares and the Bank Warrants with respect to 1,210,938
New Alliance Shares to be issued to the Bank as payment for certain fees to the
Bank and in exchange for an overriding royalty interest in certain of LaTex's
properties currently owned by the Bank, as well as the 1,210,938 New Alliance
Shares issuable upon exercise of the Bank Warrants.

  This Proxy Statement may be used in connection with the following
transactions:

     (i)    the issuance by Alliance of 21,448,787 New Alliance Shares in
  connection with the Merger, and the resale of any of such Shares by any person
  who may be deemed to be an underwriter thereof;

     (ii)   the issuance of the New Warrants by Alliance in the Merger to
  replace currently outstanding warrants issued by LaTex, and the resale of any
  of such New Warrants by any person who may be deemed to be an underwriter
  thereof;

     (iii)  the issuance by Alliance of up to 1,927,908 New Alliance Shares
  issuable on exercise of the New Warrants;

     (iv)   the issuance by Alliance of up to 2,578,125 New Alliance Shares to
  the Bank, and the resale of any such shares by any person who may be deemed to
  be an underwriter thereof;

     (v)    the issuance of the Bank Warrants by Alliance, and the resale of any
  of the Bank Warrants by any person who may be deemed to be an underwriter
  thereof; and

                                       34
<PAGE>
 
     (vi)   the issuance by Alliance of up to 1,210,938 New Alliance Shares
  issuable on exercise of the Bank Warrants.

  In connection with any resales or transfers of any of the New Alliance Shares,
New Warrants, Bank Shares or Bank Warrants by any person who may be deemed to be
an underwriter of such securities, such person will be obligated to provide to
the purchaser or transferee a copy of the Proxy Statement containing current
information with respect to Alliance and all of the matters described herein and
will be subject to all of the provisions of the Act which relate to statutory
underwriters. Alliance is not aware that, except as otherwise disclosed in this
Proxy Statement, any of such persons has, as of the date hereof, a specific plan
for the sale, transfer or other distribution of any of such securities. Such
sales, transfers or other distributions may, from time to time, include sales in
any market for such securities, including the London Stock Exchange, privately
negotiated transactions or transactions executed with or through the facilities
of one or more brokers or dealers.

REGULATORY MATTERS

  No federal, state or other regulatory approvals are required to be obtained,
nor any regulatory requirements complied with, by any party to the Merger
Agreement, except for the requirements of the DGCL in connection with the
approval of LaTex's shareholders and completion of the Merger and the
requirements of applicable federal and state securities laws.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

  In the Merger Agreement, the parties agreed that, as a condition to the
Merger, Alliance would enter into an agreement with Jeffrey T. Wilson, Chairman
and President of LaTex, satisfactory to both parties, pursuant to which Mr.
Wilson will provide certain consulting services to Alliance relating to
acquisitions in the energy industry for Alliance subsequent to the Merger. The
consulting agreement will be for a term of six months and will provide for a
monthly fee of $10,000.

  As compensation for initiating the Merger, rendering the fairness opinion and
other services in connection with the Merger, LaTex has agreed to pay Wood
Roberts a fee of $240,000 upon completion of the Merger. LaTex has also agreed
to reimburse Wood Roberts for its reasonable expenses in relation to its
services and to indemnify Wood Roberts for any liability arising from its
engagement as financial advisor to LaTex. LaTex has also agreed to pay Wood
Roberts a fee of 100,000 shares of LaTex Common Stock upon the successful
restructuring of the LaTex Credit Agreement. Because the LaTex Credit Agreement
will be restructured in connection with the Merger, Wood Roberts will receive
85,981 New Alliance Shares in payment of this fee upon completion of the Merger.
In addition, Wood Roberts and its affiliates hold warrants to purchase 756,000
shares of LaTex Common Stock at exercise prices of $0.75 to $1.20 per share.
John R. Martinson, a director of LaTex, is a principal of Wood Roberts and will
be a director of Alliance after the Merger. Mr. Martinson recused himself from
consideration of the terms of the Merger for the purpose of the fairness
opinion.

                                       35

ACCOUNTING TREATMENT

  LaTex expects the Merger will be treated as a purchase for accounting and
financial reporting purposes. Because LaTex is the larger company, this means
that the transaction will be treated as if LaTex had acquired and assumed the
operations of Alliance on the Effective Time of the Merger.

SUMMARY COMPARISON OF LATEX COMMON STOCK AND NEW ALLIANCE SHARES

  Because LaTex is incorporated under the laws of Delaware while Alliance is a
public limited company organized under the laws of England, there are a number
of differences between the attributes of the LaTex Common Stock and the New
Alliance Shares, as well as the rights and privileges of the holders of each of
them. The following summary compares a number of the principal differences. The
attributes of the New Alliance Shares described below reflect an amendment to
Alliance's Articles of Association that is to be adopted concurrently with the
Merger.

                             LATEX COMMON STOCK  
                             ------------------

                  Right to Call Meetings and Submit Proposals

As permitted by the DGCL, LaTex's Bylaws provide that the holders of at least
51% of the outstanding shares may request, in writing, a special meeting of
shareholders at any time and for any lawful purpose, specifying the matter or
matters (that are appropriate for action at a special meeting) proposed to be
presented to the meeting. Each special meeting will be held at such place as the
person or persons calling the meeting shall fix.

                              NEW ALLIANCE SHARES
                              -------------------

Under English law, notwithstanding any provision to the contrary in a company's
articles of association, an extraordinary general meeting of shareholders may be
called by a request of shareholders holding not less than one-tenth of the paid-
up capital of the company having voting rights at general meetings.

                        Conduct of Shareholder Meetings

Under the DGCL, all matters required to be approved by shareholders must be
approved by the affirmative vote of the holders of at least a majority of the
outstanding shares of LaTex Common Stock. Written notice of a meeting of
shareholders must be given, personally or by mail, not fewer than ten nor more
than sixty days before the meeting (unless otherwise required by law) to each
shareholder entitled to vote at such meeting. This notice must state the place,
date and hour of the meeting and the purpose or purposes for which the meeting
is called and the name or names of the persons who have directed the calling of
the meeting.                                        

An ordinary resolution requires 14 clear days' notice and requires a majority
vote of those present and voting. An extraordinary resolution requires 14 clear
days' notice and a three-quarters majority vote of those present and voting. A
special resolution requires 21 clear days' notice and a three-quarters majority
vote of those present and voting. An annual general meeting requires 21 clear
days' notice regardless of the type of resolution to be proposed. The term
"clear days' notice" means calendar days and excludes the day of mailing, the
deemed date of receipt of such notice (normally the day following such mailing,
if sent by first class mail) and the date of the meeting itself. "Extraordinary
resolutions" are limited to certain matters out of the ordinary course of
business, such as a proposal to wind up the affairs of the company. Proposals
that are the subject of "special resolutions" include proposals to change the
name of a company, proposals to alter a company's capital structure (but not to
increase an existing class of share capital), proposals to change or amend the
rights of shareholders, proposals to amend a company's objects (purpose clause)
and Articles of Association and proposals to carry out certain other matters
where either a company's Articles of Association or the Companies Act require a
"special resolution." Most other proposals relating to the ordinary course of a
company's business, such as the election of directors, are the subject of an
ordinary resolution. Notice of any type of meeting must

                                       36
<PAGE>
 
state the place, date and hour of the meeting and the general nature of the
business to be transacted at the meeting.

                          Right to Shareholder Lists

Shareholders of LaTex have the right, in person or by attorney or other agent,
upon written demand stating the purpose thereof, during usual business hours, to
inspect for any proper purpose a list of the names, addresses and shares held by
shareholders.                                        

The register of shareholders and index of shareholders' names of an English
company may, in general, be inspected by a shareholder during business hours
without charge, and by other persons upon payment of a charge. Any person may
request to be supplied with a copy of the whole or part of the register upon
payment of a charge.

                   Right to Inspection of Books and Records

Under the DGCL, any shareholder of LaTex, upon written request stating the
purpose of the inspection, has the right to inspect for any proper purpose
LaTex's books and records, and to make copies of those records.

A shareholder of any English company may inspect the minutes of shareholder
meetings and obtain copies (within 7 days) upon payment of a charge.
Shareholders are not entitled to inspect the accounting records of a company or
minutes of directors' meetings. However, the Secretary of State of Trade and
Industry may, on the application of at least 200 shareholders or of shareholders
holding not less than 10% of the issued share capital of a company, appoint
inspectors to investigate the affairs of the company and inspect all documents
relating of or to the company.   

Certain registers required to be kept by a company are open to public
inspection, including the Register of Directors and Secretaries, Register of
Directors' Interests in Shares and Debentures, Register of Charges, the Register
of Debenture Holders and the Register of Interests in Shares. Service contracts
of directors of the company are available for inspection in certain
circumstances and at certain times. Copies of instruments creating charges that
are registrable with the Registrar of Companies together with any other charges
in the Register of Charges of the company must be kept and be made available for
inspection by shareholders and creditors without charge.

                                 Voting Rights

The DGCL provides that, unless otherwise provided in a company's certificate of
incorporation, each shareholder is entitled to one vote for each share of stock
held by such shareholder, on each matter submitted to a vote of shareholders of
the company. LaTex's Certificate of Incorporation provides that a shareholder is
entitled to one vote for each share of LaTex Common Stock held by such
shareholder.                                        

As permitted by its Certificate of Incorporation, LaTex has filed a Certificate
of Designation providing for the issuance of preferred stock. Holders of LaTex's
preferred stock are not given any voting rights.

Under the DGCL, voting by shareholders for directors is noncumulative unless
provided otherwise in the certificate of incorporation. LaTex's Certificate of
Incorporation does not provide for cumulative voting. Therefore, LaTex currently
employs noncumulative voting. Under noncumulative voting, each shareholder
entitled to vote for directors may vote, for each director, the number of votes 
equal to the number of shares held by the shareholder. Since voting is 
noncumalative, the holders of a majority of the voting stock may elect all of 
the Directors.

Under English law, the voting rights of shareholders are governed by the
Companies Act, as amended, and by a company's articles of association.
Shareholders have the statutory right to demand a poll (a vote by the number of
shares held rather than by a show of hands) at a general meeting in certain
circumstances. Under Alliance's Articles of Association, a poll may be demanded
at any general meeting by (i) the chairman of the meeting, (ii) at least three
shareholders present in person or by proxy and having the right to vote at the
meeting, (iii) a shareholder or shareholders present in person or by proxy
representing not less than 10% of the total voting rights of all the
shareholders having the right to vote at the meetings or (iv) a shareholder or
shareholders present in person or by proxy holding shares conferring a right to
vote at the meeting, being shares on which an aggregate sum has been paid-up
equal to, but not less than 10% of the total sum paid-up on all the shares
conferring that right.

                                       37
<PAGE>
 
Cumulative voting is essentially unknown under English law. Two shareholders
present in person constitute a quorum for purposes of a meeting unless a
company's articles of association specify otherwise. Alliance's Articles of
Association specify that two persons entitled to vote on the business to be
transacted, each being a shareholder or a proxy for a shareholder or a duly
authorized representative of a corporation that is a shareholder, shall
constitute a quorum.

Subject to any special rights or restrictions attached to any shares, on the
show of hands, every shareholder who (being an individual) is present in person
or (being a corporation) is present by a duly authorized representative at any
meeting by proxy and is entitled to vote shall have one vote, and on a poll
every shareholder who is present either personally or by proxy and is entitled
to vote shall have one vote for every ordinary share held by him. Although a
proxy is normally only valid for the meeting therein mentioned, it is also valid
for any adjournment of the meeting. To be valid, the proxy must be in writing
and be deposited in accordance with Alliance's Articles of Association, which
generally requires the proxy to be delivered to Alliance no later than the last
time at which an instrument of proxy should have been delivered in order to be
valid for use at that meeting.

If there is a failure by a shareholder within 14 days to comply with a request
made by Alliance to disclose certain information regarding his shares under
Section 212 of the Act, the Board may suspend the shareholder's voting rights in
relation to such shares and, where his shareholding represents one-quarter of
one percent or more of the issued shares of any class of shares, may direct that
Alliance retain dividends or other moneys payable upon such shares and/or that
no transfer, other than an "approved transfer" as a defined in the Articles of
Association, of any such shares shall be registered.

Should all the members entitled to vote at a general meeting sign written
resolutions in lieu of a vote at such meeting, such written resolutions shall be
valid and effective as resolutions passed at a general meeting.  For as long as
Regulated Entity or its affiliates is a holder of New Alliance Shares, it will
not be entitled to vote more than 5.0% of the total votes normally exercisable
by holders of New Alliance Shares.  Upon a transfer of any New Alliance Shares
to a non-Regulated Entity, this restriction will cease to apply to those New
Alliance Shares.

                          Distributions and Dividends

LaTex has not paid any dividends on its outstanding common shares during the
last five years. In addition, LaTex is restricted from paying cash dividends
under the LaTex Credit Agreement. LaTex's Bylaws provide that the Board of
Directors, at any regular or special meeting thereof, may declare dividends upon
the issued and outstanding shares of LaTex's Common Stock, subject to the prior
payment of dividends upon any series of preferred stock outstanding. The holders
of Series B Senior Convertible Preferred Stock are paid cumulative cash
dividends at the annual rate of $1.20 per share. Subject to the prior and
superior rights of the holders of any series of LaTex's preferred stock ranking
prior and superior to the shares of Series A Convertible Preferred Stock,
including the prior and superior rights of the holders of LaTex's Series B
Senior Convertible Preferred Stock, the holders of Series A Convertible
Preferred Stock will be paid cumulative cash dividends at the annual rate of
$.20 per share. In lieu of paying cash dividends on the LaTex Series A Stock and
LaTex Series B Stock, LaTex may pay such dividends in the form of additional
shares of such preferred stock.

The ability of LaTex's Board of Directors to declare dividends for holders of
the common stock is limited by the rights and priority of holders of LaTex's
preferred stock.

Holders of New Alliance Shares will be entitled to receive such dividends as may
be declared by the Board of Directors of Alliance. All of LaTex's outstanding
preferred shares will be converted into New Alliance Shares in the Merger. In
the Merger, Alliance will be assuming LaTex's obligations under the LaTex Credit
Agreement, which will continue to prohibit Alliance from paying dividends. In
addition, Alliance is precluded from paying dividends until such time as its
retained loss is cleared or canceled by court order. Alliance has not paid any
dividends on its outstanding ordinary shares during the last five years and
currently intends to retain its

                                       38
<PAGE>
 
cash for the continued expansion of its business, including exploration,
development and acquisition activities.

                                   Dilution

LaTex's Certificate of Incorporation permits the issuance of additional shares
of common stock or shares of preferred stock, pursuant to which the interests in
the assets, liabilities, cash flow, and results of operations of LaTex
represented by the shares of LaTex Common Stock may be diluted. Under Nasdaq
rules, LaTex may not issue common stock equal to 20% or more of the then
outstanding shares in connection with the acquisition of the stock or assets of
another entity without shareholder approval. Issuances of additional shares of
common stock or preferred stock could adversely affect existing shareholders'
equity interest in LaTex and the market price of the common stock. LaTex's Board
of Directors by resolution may establish one or more classes or series of
preferred stock having the number of shares, designations, relative voting
rights, preferences, and limitations that the Board of Directors fixes without
any shareholder approval.                                        

Under the DGCL, shareholders are denied preemptive rights unless preemptive
rights are provided for in the certificate of incorporation. LaTex's Certificate
of Incorporation currently does not provide for preemptive rights. 

Without prejudice to any special rights previously conferred on the holders of
any existing shares or class of shares, any shares in the capital of Alliance
may be issued with such special rights, privileges or restrictions as Alliance
general meeting may (before the issuance of such shares) from time to time
determine.                                       

Alliance may from time to time by ordinary resolution of shareholders increase
its capital by the creation of new shares, consolidate all or any of its shares
into shares of a larger amount than its existing shares and subdivide its
existing shares or any of them into shares of smaller amount.

In connection with soliciting approval of the Merger, Alliance is also
soliciting approval of its shareholders to authorize the Board of Directors of
Alliance to issue additional New Alliance shares in an amount up to 33% of the
total outstanding shares after the Merger generally and up to 5% other than in
accordance with statutory pre-emption rights. The Board of Directors of Alliance
has indicated that it has no present intention of exercising this authority, but
may do so in the future if they deem appropriate.

                                  Liquidation

In the event of a liquidation, dissolution, or winding up of the affairs of
LaTex, after payment or provision for payment of the debts and liabilities of
LaTex, the holders of the Series B Senior Convertible Preferred Stock are
entitled to receive out of the remaining assets of LaTex $10 for each share of
Series B Senior Convertible Preferred Stock they hold, plus an amount equal to
all dividends accumulated and unpaid on each such share through the date fixed
for distribution, before any distribution may be made to holders of any shares
of Common Stock and Series A Convertible Preferred Stock. In the event of a
liquidation, dissolution, or winding-up of the affairs of LaTex, after payment
or provision for payment of debts and liabilities of LaTex, and after payment of
any prior and superior rights of any series of LaTex's preferred stock ranking
prior and superior to the shares of Series A Convertible Preferred Stock with
respect to liquidation, including the prior and superior rights of the holders
of LaTex's Series B Senior Convertible Preferred Stock, the holders of the
Series A Convertible Preferred Stock are entitled to receive out of the
remaining assets of LaTex $10 for each of the shares of Series A Convertible
Preferred Stock they hold, plus an amount equal to all dividends accumulated and
unpaid on each such share through the date fixed for distribution, before any
distribution can be made to holders of Common Stock or any other capital stock
of the Company ranking junior to the Series A Convertible Preferred Stock. After
payment to the holders of the Series A Convertible Preferred Stock, the entire
remaining assets and funds of LaTex legally available for distribution, if any,
will be distributed among the holders of Common Stock and any other capital
stock of the Company ranking junior to the Series A Convertible Preferred Stock
in proportion to the shares of such stock then held by them.

Alliances's Articles of Association provide that if the Company is wound up, a
court-appointed liquidator may, with the authority of an extraordinary
resolution and any other sanction required by law, divide among the shareholders
in specie the whole or any part of the assets of Alliance, and for that purpose,
set such values as he deems fair upon the property to be divided, and determine
how the division shall be carried out between the shareholders. The liquidator
may, with like authority, vest any part of the assets in trustees upon such
trust for the benefit for shareholders as he, with like authority shall think
fit.

                                Transferability

LaTex Shares are transferable on LaTex's books, pursuant to applicable law and
any rules as the Board of Directors may prescribe from time to time.

There are, in general, no restrictions in Alliance's Articles of Association on
the transferability of fully-paid ordinary shares. The board may in its absolute
discretion, and without giving a reason therefor, decline to register a transfer
of any share that is not fully-paid to a person of whom it does not approve or
of any share over which it has a lien. The board may also in certain
circumstances, decline to register a transfer of a share in respect of which the
shareholder has not replied to a request by the company as to the identity of
persons interested in such share. A Regulated Entity holding more than 5.0% of
the outstanding Ordinary Shares at any time will be subject to additional
transfer restrictions.                                          
                                          
                               Redemption Rights
  
LaTex, at its option and subject to conditions stated in its Certificate of
Designation, may at any time and from time to time, redeem all or any part of
the outstanding Series B Senior Convertible Preferred Stock at the rate of $10
per share of such Preferred Stock plus all dividends accumulated and unpaid on
such share through the date of redemption. Subject to the prior and superior
rights of the holders of any series of LaTex's preferred stock ranking prior and
superior to the shares of Series A Convertible Preferred Stock with respect to
redemption, including the prior and superior rights of the holders of LaTex's
Series B Senior Convertible Preferred Stock with respect to redemption, LaTex,
at its option and subject to the conditions stated in its Certificate of
Designation, may at any time and from time to time, redeem all or any part of
the outstanding Series A Convertible Preferred Stock at the rate of $10 per
share plus all dividends accumulated and unpaid on such share through the date
of redemption. LaTex Common Stock is not redeemable.

Holders of Alliance ordinary shares will have no right to surrender their shares
in exchange for the pro rata share of Alliance's net assets attributable to such
shares, and the ordinary shares are not redeemable. If Alliance shareholders so
authorize, Alliance may repurchase its shares. Any shares repurchased must be
canceled.

                               Change of Control

Certain provisions in LaTex's Certificate of Incorporation, including the
ability of the Board of Directors to issue classes or series of preferred stock
and restrictions on the ability of shareholders to call meetings and propose
business at meetings of the common shareholders, may impede a takeover attempt.
LaTex is subject to the provisions of Section 203 of the DGCL, which restricts
"business combinations" involving a company and an "interested shareholder" for
three years following the date on which the shareholder acquired 15% or more of
the outstanding voting stock of the company, unless certain statutory exceptions
are satisfied.

For a company such as Alliance listed on the London Stock Exchange, shareholder
approval may be required for certain acquisitions or disposals of assets
involving directors or substantial shareholders or their associates. In
addition, takeovers of public companies are regulated by the City Code on
Takeovers and Mergers (the "City Code"), nonstatutory 

                                       40
<PAGE>

rules that are unenforceable at law but administered by the Panel on Takeovers
and Mergers, a body comprised of representatives of certain City of London
financial and professional institutions that oversees the conduct of such
takeovers. The City Code provides that (i) when any person acquires, whether by
a series of transactions over a period of time or not, shares that (taken
together with shares held or acquired by persons acting in concert with him)
carry 30% or more of the voting rights of a public company; or (ii) when any
person, together with persons acting in concert with him, holds not less than
30% but not more than 49% of the voting rights and such person, or any person
acting in concert with him, acquires in any period of 12 months additional
shares carrying more than 1% of the voting rights, such person must generally
make an offer for all of the equity shares of the company (whether voting or
nonvoting) and all the voting non-equity shares of the company for cash, or
accompanied by a cash alternative, at not less than the highest price paid for
the relevant shares during the 12 months preceding the date of the offer.

                                Indemnification

Section 145 of the DGCL permits a corporation to indemnify any person who is, or
is threatened to be made, a party to any suit owing to the fact that the person
is or was a director, officer, employee or agent acting on behalf of the
corporation, subject to a determination by the board of directors that the
person has met certain standards of conduct. Section 145 also provides that it
is not exclusive of any other rights to indemnification or advancement of
expenses. LaTex's bylaws require indemnification of any director or officer of
LaTex to the fullest extent permitted by Delaware law and permit indemnification
of any employee, attorney, agent or representative to the extent permitted by
Delaware law. LaTex's bylaws also authorize the advancement of expenses incurred
by the Indemnitee. LaTex's Certificate of Incorporation authorizes the
indemnification of any person, in accordance with Delaware law, who is, or is
threatened to be made a party to such a suit.

Under English law, Alliance may only indemnify its officers and directors
against liabilities they incur in defending proceedings (whether civil or
criminal) in which (i) a judgment has been given in the indemnitee's favor (ii)
the indemnitee is acquitted or (iii) relief has been granted to the indemnitee
by the court from liability for negligence, default, breach of duty or breach of
trust in relation to the affairs of Alliance or its subsidiaries. The Articles
of Association of Alliance provide that directors and officers of Alliance will
be entitled to the benefit of this indemnification.

                       Limits on Management's Liability

LaTex's Certificate of Incorporation, as permitted by the DGCL, eliminates the
monetary liability of LaTex's directors for a breach of their fiduciary duty as
directors,except for liability (i) for any breach of a director's duty of
loyalty to LaTex or its shareholders, (ii) for acts or omissions not in good
faith or that involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the DGCL (which provides for liability of directors
for unlawful payment of dividends or unlawful stock purchases or redemptions),
or (iv) for any transaction from which the director derived an improper personal
benefit.

English law does not provide any mechanism for limiting the liability of
directors.

                               Appraisal Rights

Under the DGCL, a holder of LaTex Shares who does not vote in favor of a merger
or consolidation of LaTex may, upon compliance with certain procedures, be
entitled to receive the fair value of the shares in cash in lieu of the
consideration that would otherwise be received in the merger or consolidation. 
Appraisal rights are not available in certain mergers, including (a) mergers in 
which LaTex is the surviving corporation and in which no vote of its 
shareholders was required and (b) mergers when the shares were then listed on a 
national securities exchange or held of record by more than 2,000 holders and 
the holders of shares are not required to accept in exchange for their shares 
anything other than shares of stock of the surviving corporation that, on the 
effective date of the merger, would be listed on a national securities exchange 
or held of record by more than 2,000 holders, cash in lieu of fractional shares,
or any combination thereof.

While English law does not generally provide for appraisal rights, if a
shareholder applies to a court as described below, the court may specify such
terms for the acquisition as it considers appropriate.

                                       41

The Companies Act provides that where a take-over offer (as defined therein) is
made for the shares of a company incorporated in the UK and the offeror has,
within four months of the date of the offer, acquired or contracted to acquire
not less than nine-tenths in value of the shares to which the offer relates, the
offeror may, within two months of reaching the nine-tenths level, notify
shareholders who did not accept the offer and require them to transfer their
shares on the terms of the offer. A dissenting shareholder may apply to the
court within six weeks of the date on which such notice is given, objecting to
the transfer or its proposed terms. The court is unlikely (absent fraud or
oppression) to exercise its discretion to order that the acquisition not take
effect, but it may order that the offeror shall not be entitled to acquire the
relevant shares or specify such terms of the transfer as it finds appropriate. A
minority shareholder is also entitled in these circumstances to require the
offeror to acquire his shares on the terms of the offer.

                             Conflicts of Interest

LaTex's Certificate of Incorporation provides that, to the extent pro-vided by
the DGCL, no contract or transaction between LaTex and one or more of its
directors or officers or between LaTex and any other company, partnership,
association or other organization in which one or more of its directors or
officers are directors or officers of LaTex or have a financial interest, shall
be void or voidable solely for this reason, or solely because the directors or
officers are present at or participate in the meeting of the board or committee
thereof which authorizes the contract or transaction, or solely because the
directors or officers or their votes are counted for such purpose.
 
Common or interested directors may be counted in determining the presence of a
quorum at a meeting of the Board of Directors or a committee thereof which
authorizes the contract or transaction.

Alliance's Articles of Association provide that a director, or a firm in which
he is interested, may act in a professional capacity for Alliance and will be
entitled to remuneration for such services as if he were not a director, except
that such party is not authorized to act as auditor to Alliance. A director may
contract with Alliance provided he discloses his interests. Alliance's Articles
of Association also detail those matters on which an interested director may and
may not vote.

                               Trading in Shares

LaTex's Common Stock is traded on the Nasdaq SmallCap Market under the symbol
"LATX." Quotations for shares traded on Nasdaq are generally avail- able in
newspapers and other publications, as well as some computer onlineservices.
Investors may place orders for the purchase or sale of shares traded on Nasdaq
through most licensed broker dealers in the United States.

The Existing Alliance Shares are traded on the London Stock Exchange under the
symbol "ARS." Based on their knowledge of the prices and share trading activity
of small independent oil and gas companies on the London Stock Exchange,
Alliance and LaTex believe that the trading market for small independent oil and
gas companies is generally more favorable in London than in the U.S. This belief
is supported by the analysis of Wood Roberts described in detail under "The
Merger-Opinion of LaTex's Financial Advisor." Therefore, Alliance is applying
for listing on the London Stock Exchange of the New Alliance Shares to be issued
in connection with the Merger. Of course, there is no assurance that the trading
market for New Alliance Shares on the London Stock Exchange will be more
favorable than the current market for LaTex Common Stock in the U.S. Quotations
for shares listed on the London Stock Exchange are not generally readily
available in newspapers or other publications in the United States, but are
available in the daily U.S. edition of the Financial Times. However, investors
may place orders for the purchase or sale of shares traded on the London Stock
Exchange through most licensed broker 

                                       42
<PAGE>
 
dealers in the United States. Under current U.K. law, the transfer of New
Alliance Shares will generally give rise to a liability to U.K. stamp duty,
normally at the rate of 50p for every (Pounds)100 (or part thereof) of the
actual consideration paid.

RESTRICTIONS ON RESALES BY AFFILIATES

  The issuance of the New Alliance Shares to be received by LaTex shareholders
in connection with the Merger, has been registered under the Securities Act.
Except as described in this paragraph, the New Alliance Shares may be traded
without restriction under the Securities Act.  The New Alliance Shares to be
issued in the Merger and received by persons who are deemed to be "affiliates"
(as that term is defined in Rule 144 under the Securities Act) of LaTex prior to
the Merger may be resold by them only in transactions permitted by the resale
provisions of Rule 145 or other applicable exemption. The principal requirement
of Rule 145 is that an affiliate of LaTex may not (together with other persons
whose sales are aggregated under Rule 145) sell during any three-month period a
number of New Alliance Shares exceeding the greater of (i) one percent of the
total number of outstanding New Alliance Shares or (ii) the average weekly
trading volume of New Alliance Shares for a specified four-week period.

APPRAISAL RIGHTS OF DISSENTING LATEX SHAREHOLDERS

  Any person who is a holder of record of LaTex Shares and who objects to the
terms of the Merger may seek appraisal of the "fair value" of such holder's
LaTex Shares under and in compliance with the requirements of Section 262 of the
DGCL (the LaTex Shares as to which such appraisal rights have been asserted
being referred to herein as the "Dissenting Shares").  Section 262 provides a
procedure by which persons who are holders of LaTex Shares at the Effective Time
of the Merger may seek an appraisal of part or all of their LaTex Shares in lieu
of accepting New Alliance Shares in exchange therefor as described above under
"Terms of the Merger."  In any such appraisal proceeding, the Delaware Court of
Chancery (the "Chancery Court") would determine the "fair value" of the
Dissenting Shares.  Holders of LaTex Shares should recognize that such an
appraisal could result in a determination of a value higher or lower than, or
equivalent to, the New Alliance Shares they would receive in the Merger.  The
following is a summary of the principal provisions of Section 262 and does not
purport to be a complete description.  A copy of Section 262 is attached hereto
as Appendix D and is incorporated herein by reference.

  FAILURE TO TAKE ANY NECESSARY STEPS FULLY AND PRECISELY TO SATISFY THE
REQUIREMENTS OF SECTION 262 OF THE DGCL WILL RESULT IN A TERMINATION OR WAIVER
OF THE APPRAISAL RIGHTS OF THE LATEX STOCKHOLDER UNDER SUCH SECTION.  IN THAT
CASE, EACH LATEX SHARE OWNED BY SUCH STOCKHOLDER IMMEDIATELY PRIOR TO THE
EFFECTIVE DATE WILL BE CONVERTED INTO THE RIGHT TO RECEIVE NEW ALLIANCE SHARES
PURSUANT TO THE MERGER.

  Under Section 262, a corporation, not less than 20 days prior to the meeting
at which a proposed merger is to be voted on, must notify each of its
shareholders entitled to appraisal rights as of the record date of the meeting
that appraisal rights are available and include in the notice a copy of Section
262.  This Proxy Statement constitutes the notice to the holders of LaTex
Shares.

  A holder of LaTex Shares electing to exercise appraisal rights under Section
262 must (a) deliver to LaTex, before the taking of the vote on the Merger, a
written demand for appraisal that is made by or on behalf of the person who is
the holder of record of the Dissenting Shares and (b) not vote in favor of
adoption of the Merger.  A proxy or vote against approval and adoption of the
Merger does not constitute a sufficient demand.  In addition, mere failure,
after the completion of the Merger, to execute and return a letter of
transmittal to the Transfer Agent does not constitute a demand. A holder of
LaTex Shares electing to demand appraisal must do so before the taking of the
vote on the Merger by a separate written demand that reasonably informs LaTex of
the identity of the holder of LaTex Shares of record and of the holder's
intention thereby to demand the appraisal of the holder's LaTex Shares.  Written
demands for appraisal should be directed to LaTex Resources, Inc., 4200 East
Skelly Drive, Suite 1000, Tulsa, Oklahoma 74135, Attention: Stacey D. Smethers,
Secretary.

  Only the holder of record of LaTex Shares is entitled to assert appraisal
rights for the LaTex Shares registered in that holder's name.  The holder of
LaTex Shares asserting appraisal rights must hold LaTex Shares on the date of
record 

                                       43
<PAGE>
 
of making the demand and continuously through the Effective Time of the Merger.
The demand should be executed by or for the holder of record, fully and
correctly, as the holder's name appears on the holder's stock certificates. If
the stock is owned of record in a fiduciary capacity, such as by a trustee,
guardian or custodian, execution of the demand should be made in that capacity,
and if the stock is owned of record by more than one person, as in a joint
tenancy or tenancy in common, the demand should be executed by or for all
owners. An authorized agent, including one of two or more joint owners, may
execute the demand for appraisal for a holder of record; however, the agent must
identify the record owner or owners and expressly disclose the fact that, in
executing the demand, the agent is acting as agent for the record owner or
owners.

  A record holder who holds LaTex Shares as nominee for beneficial owners may
exercise the holder's right of appraisal with respect to the LaTex Shares held
for all or less than all of such beneficial owners.  In that case, the written
demand should set forth the number of shares of LaTex Shares covered by it.
Where no number of shares of LaTex Shares is expressly mentioned, the demand
will be presumed to cover all LaTex Shares held in the name of the record
holder.

    Within ten days after the Effective Time of the Merger, Alliance will send
notice of the effectiveness of the Merger to each person who, prior to the
Effective Time of the Merger, made proper written demand for appraisal and who
did not vote in favor of, or consent to, the Merger.

  Within 120 days after the Effective Time of the Merger, Alliance or any holder
of Dissenting Shares may file a petition in the Chancery Court demanding a
determination of the fair value of all of the Dissenting Shares.  Holders of
Dissenting Shares should not assume that (i) Alliance will file a petition with
respect to the appraisal value of their Dissenting Shares, (ii) Alliance will
initiate any negotiations with respect to the "fair value" of such Dissenting
Shares or (iii) Alliance will notify them of any act in connection with the
Merger other than as required by law.  Accordingly, holders of LaTex Shares
should regard it as their obligation to initiate all necessary action with
respect to the perfection of their appraisal rights within the time periods
prescribed in Section 262 of the DGCL.

  Within 120 days after the Effective Time of the Merger, any holder of
Dissenting Shares is entitled, upon written request, to receive from Alliance a
statement setting forth the aggregate number of Dissenting Shares and the
aggregate number of holders of Dissenting Shares.  Alliance is required to mail
this statement within ten days after it receives a written request therefor.

  If a petition for an appraisal is timely filed, after a hearing on such
petition, the Chancery Court will determine the holders of LaTex Shares entitled
to appraisal rights and will appraise the Dissenting Shares owned by the
holders, determining their "fair value" exclusive of any element of value
arising from the accomplishment or expectation of the Merger and will determine
a fair rate of interest, if any, to be paid upon the "fair value."  In
determining "fair value" of the Dissenting Shares, the Chancery Court will take
into account all relevant factors.  The Delaware Supreme Court has stated that
such factors include "market value, asset value, dividends, earnings prospects,
the nature of the enterprise and any other facts which were known or which could
be ascertained as of the date of merger which throw any light on future
prospects of the merged corporation."  The Delaware Supreme Court has also
stated, among other things, that "proof of value by any techniques or methods
generally considered acceptable in the financial community and otherwise
admissible in court" should be considered in an appraisal proceeding.  The value
so determined for the Dissenting Shares could be more or less than, or the same
as, the New Alliance Shares to be received in the Merger. The Chancery Court may
allocate the costs of the appraisal proceedings as it deems equitable in the
circumstances. The Chancery Court may also order that all or a portion of the
expenses incurred by any holder of Dissenting Shares in connection with an
appraisal proceeding, including, without limitation, reasonable attorneys' fees
and the fees and expenses of experts utilized in the appraisal proceeding, be
charged pro rata against the value of all the Dissenting Shares.

  Any holder of LaTex Shares who has duly demanded an appraisal in compliance
with Section 262 will not, after the Effective Time of the Merger, be entitled
to vote the LaTex Shares subject to the demand for any purpose or be entitled to
the payment of dividends or other distributions on the LaTex Shares (other than
those payable or deemed to be payable to holders of LaTex Shares of record as of
a date prior to the Effective Time of the Merger) or on any New Alliance Shares
otherwise issuable, but for the appraisal demand, in substitution therefor.

                                       44
<PAGE>
 
  A holder of LaTex Shares will fail to perfect, or effectively lose, the
holder's right to appraisal if no petition for appraisal is filed within 120
days after the Effective Time of the Merger, or if a holder of LaTex Shares
delivers to LaTex a written withdrawal of the holder's demand for an appraisal
and an acceptance of the Merger, except that any such attempt to withdraw made
more than 60 days after the Effective Time of the Merger requires the written
approval of Alliance.  Holders of LaTex Shares should also note that surrender
to the designated exchange agent of certificates for their LaTex Shares may
constitute a waiver of appraisal rights under the DGCL.

  If an appraisal proceeding is timely instituted, the proceeding may not be
dismissed, without the approval of the Chancery Court as to any holder of LaTex
Shares who has perfected his right of appraisal.

                       PRICE RANGE OF STOCK AND DIVIDENDS

  The Existing Alliance Shares are traded on the London Stock Exchange under the
symbol "ARS."LaTex's Common Stock is traded on the Nasdaq under the symbol
"LATX" and until September 4, 1996, was listed on the Pacific Stock Exchange
under the symbol "LAT," at which time it was removed from listing due to lack of
adequate trading volume. At the request of Alliance, the trading of the Existing
Alliance Shares on the London Stock Exchange was suspended upon the announcement
of the Merger Agreement and will remain suspended until completion or
abandonment of the Merger. Also at the request of Alliance, the trading of the
Existing Alliance Shares was suspended from September 6, 1995 to November 2,
1995 in connection with the investigation of the matters relating to Mr.
O'Brien, Alliance's former chief executive.

  The following table sets forth the high and low sales prices for the Existing
Alliance Shares on the London Stock Exchange (in pounds) and the high and low
closing bid prices per share of LaTex Common Stock on Nasdaq (in dollars) for
the periods indicated. Bid quotations represent quotations between dealers
without adjustment for retail mark-ups, mark-downs or commissions and may not

  As of March 14, 1997, the approximate number of record holders of the existing
Alliance shares was 2,730.

  As of March 14, 1997, the approximate number of record holders of LaTex Common
Stock was 507.

  On August 9, 1996, the last complete trading day prior to the announcement of
the Merger Agreement, the closing sales prices of LaTex Common Stock was $0.41
per share and of the Existing Alliance Shares on the London Stock Exchange was
(Pounds)0.02 per share.

  On March 14, 1997, the closing bid price of LaTex Common Stock on Nasdaq was
$0.344 per share.

  Based on their knowledge of the prices and volumes of trading of small
independent oil and gas companies on the London Stock Exchange, as reflected in
the analysis of Wood Roberts, Alliance and LaTex believe that the trading market
for small independent oil and gas companies is generally more favorable in
London than in the U.S., Alliance is applying for listing on the London Stock
Exchange of the New Alliance Shares to be issued in connection with the Merger.
See "The Merger-Opinion of LaTex's Financial Advisor." Of course, there is no
assurance that the trading market for New Alliance Shares on the London Stock
Exchange will be more favorable than the current market for LaTex Common Stock
in the U.S. Alliance does not intend to list the New Alliance Shares on any
United States stock exchange or the Nasdaq National Market System or SmallCap
Market, but anticipates that the New Alliance Shares may be traded 

                                       46

from time to time over the counter. Quotations for shares listed on the London
Stock Exchange are not generally readily available in newspapers or other
publications in the United States, but are available in the daily U.S. edition
of the Financial Times. However, investors may place orders for the purchase or
sale of shares traded on the London Stock Exchange through most licensed broker
dealers in the United States. Under current U.K. law, the transfer of New
Alliance Shares will generally give rise to a liability to U.K. stamp duty,
normally at the rate of 50p for every ((Pounds)) 100 (or part thereof) of the
actual consideration paid.

    Neither Alliance nor LaTex have paid any cash dividends on the Existing
Alliance Shares or LaTex Common Stock for at least the last two completed fiscal
years.  In addition, LaTex is restricted from paying cash dividends under the
LaTex Credit Agreement and Alliance will be restricted from paying dividends
under the Alliance Credit Agreement.

                        SPECIAL MEETING OF SHAREHOLDERS

    The Special Meeting is scheduled to be held at 9 a.m. (Local time) on April
30, 1997, at the Doubletree Downtown Hotel, 616 W. 7th, Tulsa, Oklahoma 74217.

PURPOSE OF THE MEETING

    The purpose of the Special Meeting is to consider and vote upon a proposal
to approve and adopt a proposed Agreement and Plan of Merger, dated as of August
12, 1996 as amended, among LaTex, Alliance and Alliance Resources (Delaware),
Inc., which is a newly formed, wholly owned subsidiary of Alliance, pursuant to
which, among other things, (i) Alliance Resources (Delaware), Inc. will be
merged with and into LaTex resulting in LaTex becoming a wholly owned subsidiary
of Alliance and (ii) outstanding shares of LaTex's Common Stock will be canceled
and LaTex shareholders will receive New Alliance Shares at the Conversion Rate.

QUORUM AND VOTING

    The record date for the determination of shareholders entitled to notice of
and to vote at the Special Meeting was the close of business on March 14, 1997
(the "Record Date").   As of the Record Date, there were 19,805,495 shares of
LaTex's Common Stock issued and outstanding.

    Each share of LaTex's Common Stock is entitled to one vote on all matters to
be acted upon at the Special Meeting. The presence, in person or by proxy, of
holders of a majority of the issued and outstanding shares of LaTex's Common

                                    ALLIANCE

GENERAL

  Alliance is a London-based holding company of a group whose principal
activities are the exploration, development and production of oil and gas in the
United States.  In May 1996, John A. Keenan was appointed as chief executive of
Alliance.  In connection with the change in management, Alliance has adopted a
new business strategy.  As formulated by its current management, Alliance's
near-term strategy is to focus its operations on the development, enhancement
and operation of producing properties in the United States, which would generate
the cash flow necessary to provide initial funding for international oil
development and enhancement projects, particularly in the former Soviet Union
and the Middle East.

  Alliance believes that opportunities to increase production in older or
undeveloped fields employing new technology and capital have become available
internationally as a result of the eroding geographic, political and economic
barriers to private investment, particularly in the former Soviet Union and the
Middle East.  However, realization of this strategy requires that Alliance has a
sufficient quantity of assets and cash flow to fund the process of identifying
and securing additional properties for exploitation. Therefore, in 1996,
Alliance concentrated on pursuing acquisition opportunities that would provide a
base of properties with relatively stable cash flow.

  The Board of Directors of Alliance believes that the Merger will provide
necessary critical mass to Alliance, which will enhance prospects for its
further growth and the realization of its stated objective of building an
international portfolio of development prospects.  At this time, other than
Alliance's interest in the Delvina field in Albania, discussed below, neither
Alliance nor LaTex holds any rights to international projects.  However,
Alliance's management intends to pursue additional United States acquisitions
with the ultimate intention of utilizing the cash flow generated by those
properties to fund international development, exploitation and enhancement
projects.

  Alliance was incorporated and registered under the laws of England and Wales
on August 20, 1990.  Alliance's principal executive offices are at Kingsbury
House, 15-17 King Street, London SW1Y 6QU, England.  After completion of the
Merger, Alliance will maintain corporate headquarters in London but intends that
its U.S. operations office will be located in LaTex's current offices at 4200
East Skelly Drive, Suite 1000, Tulsa, Oklahoma 74135.

RECENT DEVELOPMENTS

  Until September 1995, Mr. John O'Brien served as Alliance's chief executive
and as a director. In August 1995, the Board of Directors of Alliance questioned
Mr. O'Brien's past representations to the Board concerning Alliance's interest
in the Valentine Field in Louisiana. Thereafter, an internal investigation was
carried out that raised further issues regarding Mr. O'Brien's conduct.
Therefore, on September 6, 1995, the Alliance Board of Directors removed Mr.
O'Brien as a director and the chief executive and requested the suspension of
trading in Alliance's shares on the London Stock Exchange. After an extensive
investigation by the Board of Directors, that included work by specially engaged
forensic accountants, independent petroleum reservoir engineers and legal
counsel, Alliance determined to file litigation against Mr. O'Brien and to
report the matters to the Serious

                                       52
<PAGE>
 
Fraud Office of the United Kingdom, which continues to conduct its
investigation. On August 13, 1996, Alliance announced that it had agreed to stay
its litigation against Mr. O'Brien. The terms of the settlement are
confidential.

  D. Patrick Maley, a director of Alliance since November 29, 1995, served as
Chairman of the Company on an interim basis until May 1996.  At that time, John
A. Keenan, who had been a non-executive director of Alliance since April 1996,
was appointed as chief executive of Alliance. In addition, Alliance's Board of
Directors appointed Paul Fenemore as Director of Operations and Business
Development of Alliance in May 1996 and Brian Williams as Financial Director of
Alliance in June 1996. Accordingly, although the events surrounding Mr.
O'Brien's activities created significant turmoil within Alliance, Alliance has
now appointed new management and has adopted a new business strategy for
Alliance.

  After its fiscal year ended April 30, 1996, Alliance disposed of certain of
its properties and other assets.  Specifically, on May 13, 1996, Alliance sold
its interest in four leases offshore Matagorda Island, Texas for net cash
consideration of $432,000.  Alliance's interest in these blocks varied between
4.2% and 6.3%.  On August 15, 1996, Alliance disposed of its interest in four
leases in Lovaca County, Texas for net cash consideration of $435,000.
Alliance's working interest in these blocks varied between 17.7% and 42.4%. Also
in August 1996, Alliance disposed of its interest in Geological Forecast
Technology Ltd. to Geos Seismology Limited by transferring its 50 A Shares as
part of a final settlement of actions brought by the latter.

  In October 1996, Alliance sold its interest in three oil and gas fields
located in Texas and Oklahoma for net cash consideration of $1,425,000.  The
fields had combined remaining reserves of approximately 25,920 barrels of oil
and 1,720 million cubic feet of gas as of May 1, 1996, representing
approximately 16% of Alliance's total proved and probable reserves.  The
interest comprised 21 wells and Alliance's working interest in those wells
varied between 3% and 28%.

ACQUISITION OF OVERRIDING ROYALTY INTEREST FROM BANK

  Effective February 19, 1997, Alliance has conditionally agreed with an
affiliate of the Bank of America NT & SA (the "Bank") to acquire from the Bank
an overriding royalty interest (the "ORRI") held by the Bank in certain oil and
gas properties in which LaTex has an ownership interest. The Bank previously
acquired the ORRI from LaTex in connection with the Bank's extension of credit
to LaTex. In consideration for the ORRI, Alliance will issue to the Bank
1,343,750 New Alliance Shares, warrants to purchase 1,210,938 New Alliance
Shares and loan notes convertible into 1,078,125 New Alliance Shares.  The zero-
coupon convertible loan notes (the "Bank Notes") are convertible into 1,078,125
New Alliance Shares at any time during the period of 10 years from issuance at
the discretion of the Bank or at the option of the Company for six months
following 10 years after issuance, in each case after the payment by the Bank of
1p per share and warrants (the "Bank Warrants") will give the right to purchase
1,210,938 New Alliance Shares at an exercise price of (Pounds)1.00 per share.
The Bank Notes will be convertible in whole or in part, and if not previously
converted, will be repayable at (Pounds)1.62 per Note 10 years and six months
after issuance.  The Company has agreed, under certain circumstances, to
register the Bank Notes, the Bank Warrants and the New Alliance Shares issuable
upon conversion or exercise of the Bank Notes and Bank Warrants.  For purposes
of determining whether to acquire the ORRI, Alliance estimated the future net
revenues

                                       53
<PAGE>
 
of the ORRI as of November 1, 1996 by using escalated prices and costs
discounted at 10% per annum. For this purpose, Alliance used an oil price of
$20.00 per barrel for 1996 and 1997, $19.00 for 1998 and thereafter escalating
at an annual rate of three percent to a maximum of $40.00 and then held constant
for the life of each lease. Gas prices used were $1.90 per mmbtu for 1996 and
1997 escalating thereafter at an annual rate of three percent to $3.50 per mmbtu
and then held constant for the life of the lease. Operating expenses were based
on actual operating costs for 1996 and 1997 and then escalated at an annual rate
of three percent. On this basis Alliance estimated that the future net revenues,
discounted at 10% per annum, from the proved reserves attributable to the ORRI
at approximately $4.7 million and that additional probable and possible reserves
attributable to the ORRI. This estimate was not made on the basis required to be
used by the Commission for purposes of filings with the Commission and is not
intended to be a prediction of the actual cash flow from the ORRI, but was used
by Alliance solely to determine the appropriate consideration to be paid for the
ORRI. Alliance estimated the value of the ORRI at $3.8 million. Acquisition of
the ORRI will increase Alliance's cash flow, without significantly increasing
Alliance's capital or personnel needs, because the ORRI only burdens properties
in which LaTex already has an interest. Acquisition of the ORRI is conditioned
on the completion of the Merger, but the Merger will be completed regardless
whether the ORRI acquisition is completed.

OIL AND GAS INTERESTS

  Alliance recently completed the disposal of all of its remaining non-operated
oil and gas properties located in Texas and Oklahoma, as described above, and
currently owns and/or operates oil and gas properties with proved reserves
located in the State of Louisiana.  The net proceeds generated from the property
disposals subsequent to the April 30, 1996 fiscal year end represented
approximately 25% of Alliance's estimated future net revenue discounted at 10%
per annum as at April 30, 1996.

  As at December 1996 Alliance operated 31 producing wells and also owned non-
operated interests in four producing wells in Louisiana.  Gross daily production
for the oil and gas properties in which Alliance has an interest is
approximately 808 bopd and 981 mcfgpd as of December 15, 1996, and Alliance's
net share is 413 bopd and 193 mcfgpd.  Net proved reserves to Alliance as of
April 30, 1996 were 1,026 mbbls of oil equivalent.

  The following is a summary of Alliance's principal areas of oil and gas
production activity:

  South Elton Field.  The South Elton Field is located twelve miles north of the
town of Jennings in Jefferson Davis Parish, Louisiana.  Alliance currently has a
leasehold of approximately 664 acres and in December 1996 operated five
producing wells, two saltwater disposal wells and five shut-in wells.  The field
was discovered by Stanolind in the early 1930's.  Production has been
established in four Homeseeker (Middle Frio) Sands, five Ortego (Upper Frio)
Sands and two Marginulina (Lower Anahuac) Sands.  The productive reservoirs
occur at depths at between 7,180 to 9,300 feet.  The reservoir traps are faulted
anticlines caused by south dipping growth faults.

  Gross daily production from the field is approximately 372 bopd and 329
mcfgpd, and Alliance's net share of production is 210 bopd and 100 mcfgpd as of
December 15, 1996.  Net proved reserves to Alliance as of April 30, 1996 were
334 mboe (using a 6:1 conversion factor for gas to oil).

  Valentine Field.  The Valentine Field is located south of New Orleans in
Lafourche Parish, Louisiana.  Alliance currently has a leasehold of
approximately 77 acres and in December 1996 operated two producing wells and
seven shut-in wells.  In addition, Alliance has a non-operated interest in the
Arrowhead #1 Valentine Sugars well. The field was discovered in 1935 when Pan
American drilled the Marang # 1 well. Production has been established in Middle
Miocene Sands at depths of between 6,450-10,800 feet. Alliance's oil and gas
interests are situated on the west flank of a salt dome.

  Gross daily production from Alliance's oil and gas interests in the field as
at December 15, 1996 was approximately 145 bopd and 652 mcfgpd, and Alliance's
net share of production is 97 bopd and 92 mcfgpd as of December 15, 1996.  Net
proven reserves to Alliance as of April 30, 1996 were 113 mboe.

  Jennings Field.  The Jennings Field is located seven miles north of the town
of Jennings in Acadia Parish, Louisiana.  Alliance has a leasehold of
approximately 275 acres and operates 20 producing wells, four saltwater disposal
wells and 26 shut-in wells.  The field was discovered by the Maywood Brothers in
1901.  Production has been established in multiple Miocene age sandstone
reservoirs draped over a salt dome.

  Gross daily production from the field is approximately 110 bopd and Alliance's
net share was 77 bopd as of December 15, 1996.  Recent work activity in
November/December 1996 has increased gross production from 65 bopd to the
current level of 110 bopd.  Net proved reserves to Alliance as of April 30, 1996
are 63 mboe.

  South Crowley Field.  South Crowley Field is located 5 miles southeast of the
town of Crowley in Acadia Parish, Louisiana.  Alliance has a leasehold of
approximately 40 acres and operates one producing oil well.  The field was
discovered in the 1930's by Gulf and has been developed by many operators.
Production has been established in multiple sands ranging in age from Upper
Miocene to Middle Frio.  The Guillot #1 well was drilled in August 1992 and
completed as a flowing well from perforations at a depth of 6,743-44 feet.

  Gross daily production from the Guillot #1 well was approximately 32 bopd as
of December 15, 1996.  Net proved reserves to Alliance as of April 30, 1996 are
30 mboe.

  North Tepetate Field.  The North Tepetate Field is located 24 miles northeast
of the town of Jennings in Acadia Parish, Louisiana.  Alliance presently holds
approximately 80 acres under lease and operates one producing well and one
saltwater disposal well.  The field was discovered in the 1940's by Vincent and
Welch and production has been established in Oligocene age sands.  The reservoir
trap is an anticlinal closure between two south dipping growth faults.  The
Sweeney #3 well was drilled in July 1983 and is currently completed in the
Marginulina sands at a depth of approximately 7,000 feet.

  Gross daily production from the Sweeney #3 well is approximately 29 bopd and
Alliance's net share of production was 11 bopd as of December 15, 1996.  Net
proved reserves to Alliance as of April 30, 1996 were 19 mboe.

  Jefferson Island Field.  The Jefferson Island field is located near the town
of Delcambre, approximately 9 miles west of the city of New Iberia in Iberia
Parish, Louisiana.  Alliance is operator for a 525 acre leasehold which is
currently being maintained by production from the Will Drill Resources (Texaco)
#4 JISMC well.  The Alliance lease has five shut-in wells located on it.  The
field was discovered by Texaco in May 1938.  Since then production has been
established by various operators in Siphoni Divisi and Discorbis B age sandstone
reservoirs.  The reservoir traps are combination structural-stratigraphic traps
in a salt dome piercement setting.  Alliance currently has not established
production on the lease and net proved (behind pipe) reserves to Alliance as of
April 30, 1994 were 15 mboe of oil.  A number of potential drilling locations
have been identified on the lease for future exploration activity.

FINANCING

  A subsidiary of Alliance has entered into a Credit Agreement (the "Alliance
Credit Agreement") with Bank of America NT & SA (the "Bank") effective as of
March 19, 1997, amending and restating LaTex's Amended and Restated Credit
Agreement dated as of October 20, 1995 between LaTex Petroleum Corporation,
LaTex/GOC Acquisition, Inc. and Germany Oil Company (the "Existing Borrowers"),
as borrowers, and the Bank, as the lender (the "LaTex Credit Agreement"), in
order to restructure LaTex's existing indebtedness to the Bank.  As a
restructuring fee, in connection with entering into the Alliance Credit
Agreement, Alliance agrees to issue to the Bank the 156,250 New Alliance Shares
and to pay the Bank $150,000, payable in cash or, at Alliance's option, further
zero coupon convertible loan notes.

  Under the Alliance Credit Agreement principal payments will be suspended until
October 31, 1998 following completion of the Merger. However, cash flows
generated by Alliance and its subsidiaries in excess of amounts shown in the
business plan that formed the basis of negotiation with the Bank will be used to
reduce outstanding principal indebtedness.  The maturity date of the existing
line of credit remains at March 31, 2000.

  Substantially all of the existing security for the outstanding indebtedness
under the LaTex Credit Agreement, being the mortgages of all of LaTex's
producing oil and gas properties and pledges of stock of the Existing Borrowers
and ENPRO, remains in place.  As additional security, the Bank is receiving
mortgages on substantially all of Alliance's producing oil and gas properties
and pledges of the stock of Alliance's subsidiaries.

  Under the Alliance Credit Agreement, the borrowing base will be equal to the
outstanding indebtedness under the LaTex Credit Agreement as of the date of the
Merger.  The borrowing base is to be redetermined semiannually as of December 31
and June 30 of each year.

  Borrowing under the Alliance 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 Alliance Credit Agreement) plus 1 1/4%.  Borrowing under the
Alliance 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 Alliance Credit Agreement), at a 

                                       56
<PAGE>
 
fluctuating rate equal to the LIBO Rate (Reserve Adjusted) (as defined in the
Alliance Credit Agreement) plus 2%.

  As a condition to the Bank making the loans under the LaTex Credit Agreement,
LaTex's subsidiary, LaTex Petroleum, entered into hedging agreements with the
Bank designed to enable LaTex to (a) obtain agreed upon net realized prices for
LaTex's oil and gas production (the "Oil and Gas Hedging Agreements") and (b)
protect LaTex against fluctuations in interest rates with respect to the
principal amounts of all loans under the LaTex Credit Agreement.  Under the
Alliance Credit Agreement, the Bank has agreed to make available, at its sole
discretion, to Alliance the amount of $2,500,000 to reduce or terminate the Oil
and Gas Hedging Agreements.

INTERNATIONAL

  In Albania, Alliance held the negotiating rights to the Delvina gas and
condensate field and rights, negotiated by the previous management, for
production enhancement at the Kucova/Arrza oil fields. Following a review of the
prospects by its technical staff, it was determined to focus on the Delvina
Field, as the Kucova/Arrza wells were not sufficiently productive to obtain
economic returns. Accordingly, Alliance has notified Albpetrol, the Albanian
national oil company, that it has relinquished its exclusive negotiating right
to the Kucova/Arrza Fields.

  Alliance continued its studies and negotiations with Albpetrol in respect of
participation in the Delvina gas condensate field in Albania.  The studies
confirmed that at least one new gas pipeline with a minimum length of in excess
of 80 kilometers, connecting Delvina with the main Albanian gas market, would
have to be laid due to the poor condition of the existing pipeline, which is
currently unserviceable. The large up-front capital expenditure on the new
pipeline, in conjunction with the high costs and risk associated with fracture
stimulation of the tight Delvina limestone unit, renders the economics of the
project marginal.  Alliance's exclusive rights to negotiate terms of
participation in the Delvina field lapsed in February 1997 and Alliance has
determined that it will not pursue an extension of these rights.

  Alliance continues to appraise international opportunities with particular
emphasis on the former Soviet Union.  A number of oil and gas opportunities in
Russia and Kazakhstan were identified during the period although Alliance is
awaiting completion of the proposed Merger before finalizing its international
strategy.

OPERATIONS

  For the year ended April 30, 1996, Alliance carried out the following
activities on its oil and gas properties.  In March 1995 Alliance successfully
drilled and completed the Tupper #7 well in South Elton Field, Jefferson Davis
Parish, Louisiana.  The well initially produced upwards of 168 barrels of oil
per day (bopd) and 160 thousand cubic feet of gas per day and was a significant
contributor to revenue during the year. In April 1996 Alliance completed the
workover of the Valentine Sugars #3 well which added 120 bopd to production from
the well which had been shut-in since December 1993.

                                       57
<PAGE>
 
  The Gueno #1 well was drilled in July 1995 in the Branch Field in Acadia
Parish, Louisiana and has been temporarily abandoned.  The well encountered two
of the four objective productive sands, but at downdip locations.  The leasehold
has been maintained for redrill at an upstructure location. In September 1995
the Jefferson Island Salt Mining Company #1 well was drilled in Iberia Parish.
The well was abandoned following the drill pipe being stuck and the hole junked.
Alliance has received a number of farmout proposals on this lease and is
actively considering its strategy having recently completed extensive geological
re-mapping and re-appraisal of the lease.  In October 1995 Alliance farmed out
its interest in Valentine Sugars #2 well to American Explorer.  The well was
unsuccessful and was plugged and abandoned.

  Alliance completed its review of non-core assets after the fiscal year end,
notably the nonoperated properties owned by the wholly-owned subsidiary ARNO
Inc. Subsequent to the year end, these properties have been disposed of for a
cash consideration in excess of US$2.250 million. Following a review of the US
operations, Alliance also made some significant cuts to its overhead
commensurate with the size of the operations.

RESERVES

  Ryder Scott Company ("Ryder Scott"), independent petroleum engineering
consultants, has prepared a reserve report with respect to properties having
approximately 71% of the total value of Alliance's proved reserves at April 30,
1996.  Alliance's internal engineers have estimated the Proved Reserves
attributable to Alliance's remaining properties, as well as the estimated future
net cash flows therefrom, at the same date.  The information presented below and
elsewhere in this Proxy Statement with respect to Alliance's properties is based
on the Ryder Scott reserve report and the estimates of Alliance's internal
engineers. Alliance believes that the description contained in this Proxy
Statement of the report and these estimates is fair and accurate.

  The quantities of Alliance's proved reserves of oil and natural gas presented
below include only those amounts that Alliance 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
that 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 Alliance's proved
developed reserves.  Alliance's proved undeveloped reserves include only those
quantities that Alliance 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 risk of recovering proved developed reserves.

  Set forth below are estimates as of April 30, 1996 of Alliance'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

                                       58
<PAGE>
 
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. Additional information concerning Alliance's reserves is included in
"Supplemental Oil and Gas Data" in the Notes to Alliance's Financial Statements
beginning on page F-36.

  The following table sets forth estimates of the proved oil and natural gas
reserves of Alliance at April 30, 1996.

April 30, 1996.

  The estimation of oil and gas reserves is a complex and subjective process
that 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 Alliance's proved reserves have not been filed or included in
reports to any United States' authority or agency.  Alliance has filed estimates
of proved reserves with the London Stock Exchange.  These estimates do not
differ materially from those contained in this Proxy Statement.

  For further information on reserves, costs relating to oil and gas activities,
and results of operations from producing activities, see page F-36 to Alliance's

  Productive wells consist of producing wells and wells capable of production,
including gas wells awaiting pipeline connections to commence deliveries and oil
wells awaiting connection to production facilities. Wells that are completed in
more than one producing horizon are counted as one well. Of the gross wells
reported above, none had multiple completions.

  The following table sets forth the developed and undeveloped leasehold acreage
held by Alliance at April 30, 1996. Developed acres are acres that are spaced or
assignable to productive wells. Undeveloped acres are acres on which wells have
not been drilled or completed to a point that would permit the production of
commercial quantities of oil and gas, regardless of whether or not such acreage
contains proved reserves.  Gross acres are the total number of acres in which
Alliance has a working interest.  Net acres are the sum of Alliance's fractional
interests owned in the gross acres.

  At April 30, 1996, Alliance was not participating in the drilling or
completion of any oil and gas wells.

PRODUCT MARKETING

  Alliance's production is primarily from developed fields close to major
pipelines or refineries and established infrastructure.  As a result, Alliance
has not experienced any difficulty in finding a market for all of its product as
it becomes available or in transporting its product to these markets.

  Oil Marketing.  Alliance markets its oil to a variety of purchasers, most of
which are large, established companies. The oil is generally sold under  short-
term contracts with the sales price based on an applicable posted price, plus a
negotiated premium. This price is determined on a well-by-well basis and the
purchaser generally takes delivery at the wellhead.

  Natural Gas Marketing.  Virtually all of Alliance's natural gas production is
close to existing pipelines and, consequently, Alliance generally has a variety
of options to market its natural gas.  Alliance sells the majority of its
natural gas on the spot market with prices fluctuating month-to-month based on
published pipeline indices with slight premiums or discounts to the  index.

SIGNIFICANT OIL AND NATURAL GAS PURCHASERS

  Oil and natural gas sales from operated properties are made under short-term
contracts at the current area market price as adjusted for the relevant premium
or discount. The loss of any purchaser would not be expected to have a material
adverse effect upon operations. For the period ended April 30, 1996, Alliance
sold 10% or more of its net production of oil to Texaco Trading and
Transportation, Inc. Alliance's gas production was largely from non-operated
properties for which revenues are received directly from the operator rather
than a third party.

TITLE TO PROPERTIES

  As is customary in the oil and natural gas industry, Alliance conducts only a
perfunctory title examination at the time properties believed to be suitable for
drilling operations are first acquired.  Prior to commencement of drilling
operations, a thorough drill site title examination is normally conducted and
curative work is performed with respect to significant defects.  During
acquisitions, title reviews are performed on all properties; however, formal
title opinions are obtained on only the higher value properties.

  At January 31, 1997, Alliance had eight management and administrative
employees and seven technical and operating employees.

COMPETITION

  The oil and natural gas industry is highly competitive in all its phases.
Alliance encounters strong competition from many other energy companies in
acquiring economically desirable producing properties and drilling prospects and
in obtaining equipment and labor to operate and maintain its properties.  In
addition, many energy companies possess greater resources than Alliance.

LITIGATION

  Alliance is party to the following litigation:

  Alliance is seeking to recover $1,300,000 of unpaid drilling costs from
Drexco, Inc., Drexco, Inc. and H. Huizenga claim unspecified damages with
respect to the conduct and removal of Alliance Resources (USA) Inc as operator
of the Valentine field.  Alliance has obtained legal advice and will vigorously
prosecute its claim against Drexco, Inc.  Alliance denies the counter claim and
will vigorously defend the matter.

  Alliance received, on September 12, 1996, a writ from Best Royalties Plc
claiming $186,368 and declaring that they are entitled to a sum equal to 40 per
cent of Alliance USA, Inc.'s net cash proceeds received from the Arrowhead well
(and payment of the said sum), or in the alternative damages plus interest
thereon.  Alliance denies the claim and will vigorously defend this matter.

  Ernest M. Closuit et al has asserted a claim against Alliance for alleged
underpayment of amounts due for Ernest M. Closuit et al's interest in the Buller
No. 2 well in the South Elton field and has further claimed an interest in past
and future production from certain other wells in the field.  Total claims
amount to approximately $1,200,000.  Discovery has just begun.  Alliance denies
all allegations and claims and will vigorously defend this matter.

REGULATION

  The availability of a ready market for oil and gas production depends upon
numerous factors beyond Alliance's control. These factors include regulation of
natural gas and oil production, federal and state regulations governing
environmental quality and pollution control, state limits on allowable rates of
production by well or proration unit, the amount of natural gas and oil
available for sale, the availability of adequate pipeline and other
transportation and processing facilities and the marketing of competitive fuels.
State and federal regulations generally are intended to prevent waste of natural
gas and oil, protect rights to produce natural gas and oil between owners in a
common reservoir, control the amount of natural gas and oil produced by
assigning allowable rates of production and control contamination of the
environment. Pipelines are subject to the jurisdiction of various federal, state
and local agencies. The following discussion summarizes the regulation of the
United States oil and gas industry and is not intended to constitute a complete
discussion of the various statutes, rules, regulations and governmental orders
to which Alliance's operations may be subject.

  Regulation of Natural Gas and Oil Exploration and Production. Alliance's
operations are subject to various types of regulation at the federal, state and
local levels. Such regulation includes requiring permits for the drilling 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 drilled in, the
plugging and abandoning of wells and the disposal of fluids used in connection
with operations. Alliance's operations are also subject to various conservation
laws and regulations. These include the regulation of the size of drilling and
spacing units or proration units and the density of wells that may be drilled in
and the unitization or pooling of oil and gas properties. 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 ratability of production. The effect of these
regulations may limit the amount of oil and gas that Alliance can produce from
its wells and may limit the number of wells or the locations at which Alliance
can drill. The regulatory burden on the oil and gas industry increases
Alliance's costs of doing business and, consequently, affects profitability.
Inasmuch as such laws and regulations are frequently

                                       62
<PAGE>
 
expanded, amended and reinterpreted, Alliance is unable to predict the future
cost or impact of complying with such regulations.

  Federal Regulation of Sales and Transportation of Natural Gas.  Federal
legislation and regulatory controls in the U.S. have historically affected the
price of the natural gas produced by Alliance and the manner in which such
production is marketed.  The Federal Energy Regulatory Commission (the "FERC")
regulates the interstate transportation and sale for resale of natural gas by
interstate and intrastate pipelines. The FERC previously regulated the maximum
selling prices of certain categories of gas sold in "first sales" in interstate
and intrastate commerce under the Natural Gas Policy Act.  Effective January 1,
1993, however, the Natural Gas Wellhead Decontrol Act (the "Decontrol Act")
deregulated natural gas prices for all "first sales" of natural gas, which
includes all sales by Alliance of its own production.  As a result, all sales of
Alliance's domestically produced natural gas may be sold at market prices,
unless otherwise committed by contract.  The FERC's jurisdiction over natural
gas transportation and gas sales other than first sales was unaffected by the
Decontrol Act.

  Alliance's natural gas sales are affected by the regulation of intrastate and
interstate gas transportation.  In an attempt to restructure the interstate
pipeline industry with the goal of providing enhanced access to, and competition
among, alternative natural gas supplies, the FERC, commencing in April 1992,
issued Order Nos. 636, 636-A and 636-B ("Order No. 636"), which have altered
significantly the interstate transportation and sale of natural gas.  Among
other things, Order No. 636 required interstate pipelines to unbundle the
various services that they had provided in the past, such as sales, transmission
and storage, and to offer these services individually to their customers.  By
requiring interstate pipelines to "unbundle" their services and to provide their
customers with direct access to pipeline capacity held by them, Order No. 636
has enabled pipeline customers to choose the levels of transportation and
storage service they require, as well as to purchase natural gas directly from
third-party merchants other than the pipelines and obtain transportation of such
gas on a non-discriminatory basis.  The effect of Order No. 636 has been to
enable Alliance to market its natural gas production to a wider variety of
potential purchasers.  Alliance believes that these changes generally have
improved Alliance's access to transportation and have enhanced the marketability
of its natural gas production.

  To date, Order No. 636 has not had any material adverse effect on Alliance's
ability to market and transport its natural gas production. However, Alliance
cannot predict what new regulations may be adopted by the FERC and other
regulatory authorities, or what effect subsequent regulation may have on
Alliance's activities. In addition, Order No. 636 and a number of related orders
were appealed. Recently, the United States Court of Appeals for the District of
Columbia Circuit issued an opinion largely upholding the basic features and
provisions of Order No. 636. However, even though Order No. 636 itself has been
judicially approved, several related FERC orders remain subject to pending
appellate review and further changes could occur as a result of court orders or
at the FERC's own initiative.

  In recent years the FERC also has pursued a number of other important policy
initiatives that could significantly affect the marketing of natural gas.  Some
of the more notable of these regulatory initiatives include (i) a series of
orders in individual pipeline proceedings articulating a policy of generally
approving the voluntary divestiture of interstate natural gas pipeline-owned
gathering facilities to pipeline affiliates, (ii) the completion of a rulemaking
involving the regulation of interstate natural gas pipelines with marketing
affiliates under Order No. 497, (iii) FERC's on-going efforts to promulgate
standards for pipeline electronic bulletin boards and electronic data exchange,
(iv) a generic inquiry into the pricing of interstate pipeline capacity, (v)
efforts to refine FERC's regulations controlling the operation of the secondary
market for released interstate natural gas pipeline capacity, and (vi) a policy
statement regarding market-based rates and other non-cost-based rates for
interstate pipeline transmission and storage capacity.  Several of these
initiatives are intended to enhance competition in natural gas markets. While
any resulting FERC action would affect Alliance only indirectly, the ongoing, or
in some instances, preliminary evolving nature of these regulatory initiatives
makes it impossible at this time to predict their ultimate impact upon
Alliance's activities.

  Oil Price Controls and Transportation Rates.  Sales of crude oil, condensate
and gas liquids by Alliance are not currently regulated and are made at market
prices.  Commencing in October 1993, the FERC has modified its regulation of oil
pipeline rates and services in order to comply with the Energy Policy Act of
1992.  That Act mandated the FERC to streamline oil pipeline ratemaking by
abandoning its old, cumbersome procedures and issue new procedures to be
effective January 1, 1995.  In response, the FERC issued a series of rules
(Order Nos. 561 and 561-A) establishing an indexing system under which oil
pipelines will be able to change their transportation rates, subject to
prescribed ceiling levels.  The FERC's new oil pipeline ratemaking methodology
was recently affirmed by the Court.  Alliance is not able

                                       63
<PAGE>
 
at this time to predict the effects of Order Nos. 561 and 561-A, if any, on the
transportation costs associated with oil production from Alliance's oil
producing operations.

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

  The EPA and various state agencies have limited the approved methods of
disposal for certain hazardous and nonhazardous wastes.  Certain wastes
generated by Alliance's oil and natural gas operations that are currently exempt
from treatment as "hazardous wastes" may in the future be designated as
"hazardous wastes," and therefore be subject to more rigorous and costly
operating and disposal requirements.

  Alliance currently owns or leases numerous properties that for many years have
been used for the exploration and production of oil and gas.  Most of these
properties have been operated by prior owners, operators and third parties whose
treatment and disposal or release of hydrocarbons or other wastes was not under
Alliance's control.  These properties and the wastes disposed thereon may be
subject to Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA"), Federal Resource Conservation and Recovery Act and analogous state
laws.  Under such laws, Alliance could be required to remove or rededicate
previously disposed wastes (including wastes disposed of or released by prior
owners or operators) or property contamination (including groundwater
contamination) or to perform remedial plugging operations to prevent future
contamination.

  Alliance's operations may be subject to the Clean Air Act ("CAA") and
comparable state and local requirements. Certain provisions of CAA may result in
the gradual imposition of certain pollution control requirements with respect to
air emissions from the operations of Alliance.  The EPA and states have been
developing regulations to implement these requirements.  Alliance may be
required to incur certain capital expenditures in the next several years for air
pollution control equipment in connection with maintaining or obtaining
operating permits and approvals addressing other air emission-related issues.
However, Alliance does not believe its operations will be materially adversely
affected by any such requirements.

  Federal regulations require certain owners or operators of facilities that
store or otherwise handle oil, such as Alliance, to prepare and implement spill
prevention, control, countermeasure and response plans relating to the possible
discharge of oil into surface waters.  The Oil Pollution Act of 1990 ("OPA")
contains numerous requirements relating to the prevention of and response to oil
spills into waters of the United States.  The OPA subjects owners of facilities
to strict joint and several liability for all containment and cleanup costs and
certain other damages arising from a spill, including, but not limited to, the
costs of responding to a release of oil to surface waters.  Regulations are
currently being developed under the OPA and state laws concerning oil pollution
prevention and other matters that may impose additional regulatory burdens on
Alliance.

  Alliance also is subject to a variety of federal, state and local permitting
and registration requirements relating to protection of the environment.
Management believes that Alliance is in substantial compliance with current
applicable environmental laws and regulations and that continued compliance with
existing requirements will not have a material adverse impact on Alliance.

                              UNAUDITED PRO FORMA
                       FINANCIAL STATEMENTS OF ALLIANCE

  The following unaudited condensed pro forma combined balance sheet and
unaudited condensed pro forma combined statement of income for Alliance
(collectively, the "unaudited pro forma financial statements") have been
prepared to illustrate the estimated effect of the proposed combination of
Alliance and LaTex pursuant to the Merger and the acquisition of the Bank of
America Overriding Royalty Interest and are based upon the assumptions set forth
below and in the notes to such statements. The respective historical
consolidated financial statements of Alliance and LaTex are included elsewhere
in this Proxy Statement.

  The merger will be treated as a purchase and, as a result of the LaTex
shareholders owning approximately 73% of the combined company prior to issuance
of New Alliance Shares, Bank Notes and Bank Warrants to the Bank, LaTex will be
treated as having acquired Alliance. Accordingly, in the unaudited pro forma
financial statements, it is the assets and liabilities of Alliance that are
recorded at fair value while the assets of LaTex are recorded at historical
cost.

  The unaudited pro forma financial statements include the unaudited condensed
pro forma combined balance sheet at October 31, 1996, giving effect to the
Merger and the purchase of the Bank of America Overriding Royalty Interest as if
these were consummated on that date. Also presented is the unaudited condensed
pro forma combined statement of income for the year ended April 30, 1996 and the
unaudited condensed pro forma combined statement of income for the six months
ended October 31, 1996 after giving effect to the Merger and the purchase of the
Bank of America Overriding Royalty Interest as if these were consummated on May
1, 1995.

  The unaudited pro forma financial statements are prepared in accordance with
US GAAP.  The financial statements of Alliance have been prepared in accordance
with UK GAAP and the financial statements of LaTex have been prepared in
accordance with US GAAP.  Included are relevant adjustments to the Alliance
financial statements to state these in accordance with US GAAP.

  The unaudited pro forma financial statements and accompanying notes, which are
an integral part of such statements, should be read in conjunction with the
respective historical financial statements, including the notes thereto, and
other financial information of Alliance and LaTex included elsewhere in this
Proxy Statement.  The unaudited pro forma financial statements are provided for
illustrative purposes only and do not purport to represent what the financial
position or results of operations of Alliance and LaTex would actually have been
if the Merger and the purchase of the Bank of America Overriding Royalty
Interest had in fact occurred on the dates indicated or to project the financial
position or results of operations for any future date or period.

               NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

The unaudited pro forma financial statements include the following adjustments:

CONDENSED PRO FORMA COMBINED BALANCE SHEET

Alliance US GAAP adjustments:

(a)  To eliminate from 'other receivables' an amount recognized as a receivable,
     under UK GAAP, relating to the right to receive the proceeds of the sale of
     Alliance shares resulting from the settlement with Mr. O'Brien.  Under US
     GAAP, such proceeds are recognized only on receipt.

(b)  To adjust the oil and gas properties as at October 31, 1996 to reflect the
     cumulative effect of the ceiling test write down made in the year ended
     April 30, 1995 under US GAAP.  Under US GAAP ceiling tests are computed at
     current prices discounted to present value at 10%; under UK GAAP, a ceiling
     test is based on the company's best estimate of the future cash flows from
     the underlying properties.

Pro forma adjustments:

(c)  To record the Alliance oil and gas properties at their fair values under US
     GAAP.

     The purchase price has been derived from Alliance's market capitalization
     at the date of the announcement of the merger based on a price of 2 pence
     per share and 324,152,640 shares in issue. This has been converted to U.S.
     dollars at a rate of US$1.5511:(Pounds)1. The costs of the acquisition have
     also been included to arrive at a total consideration of $11,053,000 which
     has been allocated as follows:

                                                             $000

               Fixed assets                                  8,913
               Cash                                          2,515
               Other net current assets and liabilities       (281)
               Debt                                            (94)
                                                            ------ 
                                                            11,053
                                                            ======

(d)  To record an accrual for the expenses of the merger and the share issue
     (including the restructuring fee payable to Bank of America of $200,000
     which is to be settled by the issue of 156,250 shares).

(e)  To eliminate the existing capital and reserves of Alliance (other than the
     par value of the Ordinary shares) from the condensed pro forma combined
     balance sheet.

(f)  To record the par value of the New Alliance shares to be issued as a
     consequence of the Merger and their exchange for the whole of the issued
     share capital of LaTex. This represents 21,448,787 shares of 40p each at an
     exchange rate of $1.6667:(Pounds)1.

(g)  To record the revised maturity of LaTex's bank borrowing following the
     renegotiation referred to under "Alliance-Financing" in this Proxy
     Statement.

                                       71
<PAGE>
 
(h)  To record the issue of 1,343,750 shares of 40p each, Loan notes convertible
     into up to 1,078,125 New Alliance Shares and 1,210,938 warrants to acquire
     shares at an option price of (Pound)1.00 per share to Bank of America in
     exchange for the Overriding Royalty Interest.

CONDENSED PRO FORMA COMBINED STATEMENTS OF INCOME

Alliance US GAAP adjustments:

(a)  To eliminate income recognized under UK GAAP, relating to the right to
     receive proceeds from the sale of Alliance shares resulting from the
     settlement with Mr. O'Brien. Under US GAAP, such proceeds are recognized
     only on receipt.

(b)  To adjust the depreciation, depletion and amortization charge to reflect
     the ceiling test write down adjustment made in the condensed pro forma
     combined balance sheet described above.

Pro forma adjustments:

(c)  To adjust the depreciation, depletion and amortization charge to reflect
     the adjustments made to Alliance's oil and gas properties restated at their
     fair value under US GAAP using LaTex accounting policies. LaTex uses the
     successful efforts method of accounting for oil and gas properties whereas
     Alliance uses the full cost method.

(d)  The weighted average number of shares outstanding and the loss per share
     have been calculated after giving retroactive effect to the proposed 40:1
     reverse stock split.

(e)  To reflect the sale of oil and gas properties by Alliance under LaTex's
     accounting policies. Alliance uses the full cost method under which
     (generally) the proceeds of the sale of oil and gas properties reduces the
     carrying value of the full cost pool. Under the successful efforts method
     used by LaTex the profit or loss on disposal of each property is recognized
     in the income statement at the time of sale.

(f)  To reflect the acquisition of the Overriding Royalty Interest.

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

GENERAL

  The information in this "Management's Discussion and Analysis of Financial
Condition and Results of Operations" refers to the Consolidated Financial
Statements of Alliance included in this Prospectus which are prepared in
accordance with UK GAAP.  UK GAAP differs in certain significant respects from
US GAAP.  A discussion of the principal differences is set out in Note 29 to
Alliance's Consolidated Financial Statements.  The Consolidated Financial
Statements contain a reconciliation of loss after tax (net loss) and
shareholders' equity to US GAAP.

  Alliance's operating results are affected by a variety of factors, the most
significant of which is crude oil and natural gas prices.  Lower product prices
have a negative effect on the operating income and cash flow of Alliance.  For a
summary of other factors which may affect Alliance's operating results and
financial condition, see "Risk Factors."  Although Alliance is organized in the
United Kingdom, all of its operations are located in the United States and its
financial statements are presented in U.S. dollars.  Therefore, fluctuations in
the exchange rate of the pound sterling to the U.S. dollar do not significantly
impact the revenues and net income of Alliance.

SIX MONTHS ENDED OCTOBER 31, 1996 COMPARED WITH SIX MONTHS ENDED OCTOBER 31,
1995

  Operating Results

  Production.  Despite the sale of certain non-core, predominantly gas producing
  ----------                                                                    
properties, Alliance's production in the six months to October 31, 1996 amounted
to 93,000 boe, only marginally lower than production for the comparable six
months last year of 98,000 boe. This reflects the increase in oil volumes in the
current period, which is largely the result of improved production from the
successful workover program on the Valentine field and the successful well
drilled on the South Elton field.

  All Alliance production came from the US. Natural gas represented
approximately  15% of total production in the six months to October 31, 1996
compared with 52%  in the equivalent six months in 1995.

  Sales.  Total sales increased 29% from $1.551 million in the six months to
  -----                                                                     
October 31, 1995 to $1.998 million in the six months to October 31, 1996,
reflecting the firmer prices together with the increase in oil production and
decrease in gas production.

  Louisiana South Sweet crude fluctuated between $17.50 per barrel and $24.25
per barrel during the current six months. Alliance's average crude oil price
realized for the six months to October 31, 1996 was $21.39 per barrel compared
with $16.81 per barrel in the equivalent period in 1995.

  The realized average natural gas price increased from $1.46 per thousand cubic
feet in 1995 to $2.41 per thousand cubic feet in 1996.

  Costs and expenses. The operating costs for the six months to October 31, 1996
  ------------------                                                            
were $0.817 million, against $1.089 million in the equivalent period in 1995, a
decrease of 25%. This decrease resulted from a combination of increased
efficiencies in field operations, which included the replacement of direct staff
with contract gaugers, slightly lower production and a reclassification of
workover rig and field equipment income as a reduction in operating costs
(rather than as additional income).

  Depletion on oil and gas interests which is calculated on a unit of production
(boe) basis, amounted to $0.785 million, reflecting the upward revision of
reserves at April 1996 together with slightly lower production volumes.  The
depletion charge for the comparable period last year amounted to $1.150 million.

  The exceptional costs arising from irregularities in the six months to October
31, 1995 of $0.499 million, relate primarily to professional fees incurred in
connection with the investigations into the involvement of Mr. O'Brien in the
affairs of Alliance.  The exceptional costs arising from irregularities in 1996
of $0.120 million relate to additional professional fees incurred in connection
with the aforementioned investigations.

                                       73
<PAGE>
 
  The general and administrative expenses incurred in the six months to October
31, 1996 amounted to $1.351 million compared with $1.433 million in the
equivalent period last year.  The six months to October 31, 1995 included a
number of non-recurring items which were incidental to the investigation into
the activities of Mr. O'Brien.

  Loss before and after tax (Net loss).  The loss before and after tax was
  ------------------------------------                                    
$0.987 million for the current six months compared with a loss of $2.388 million
in 1995. The improvement stemmed from the increase in revenues resulting from
the firmer oil prices in the current period, lower operating costs arising from
improved efficiencies and a significant decrease in exceptional costs.

  Net interest income decreased from net interest payable of $0.232 million in
the six months to October 31, 1995 to net interest receivable of $0.87 million
in  the current six months.  The decrease reflects the lower average cash
balances  held this year.  Interest as at October 1995 reflected the cash
balances  following the open offer and share placing in May 1995.

  Loss per Ordinary Share for the six months to October 31, 1996 was (0.3) cents
compared with the loss per Ordinary Share for the six months to October 31, 1995
of (0.8) cents.

1996 COMPARED WITH 1995

  Operating Results

  Production.  In the year ended April 30, 1996, Alliance's production amounted
  ----------                                                                   
to 225,000 barrels of oil equivalent ("boe"). The increase of 158% in Alliance's
production over 87,000 boe in the year April 30, 1995 was principally due to the
inclusion of a full year's contribution from Source Petroleum Inc. (which was
acquired by Alliance on January 25, 1995) and a full year's contribution from
the producing assets acquired by Alliance from North American Gas Investment
Trust PLC (NAGIT) on April 10, 1995. Production was also enhanced by the
successful drilling during the year ended April 30, 1996 of a well on the South
Elton field.

  All Alliance production came from the U.S.  Natural gas represented
approximately 45% of total production in both 1996 and 1995.

  Sales.  Louisiana, South Sweet crude oil prices fluctuated between $15.00 per
  -----                                                                        
barrel and over $23.25 per barrel during the year ended April 30, 1996.
Alliance's average crude oil price realized in 1996 was $18.36 per barrel
compared with $16.53 per barrel in 1995.  Total sales increased by 148% from
$1.483 million in 1995 to $3.686 million in 1996, reflecting the significant
increase in production.

  In 1996 and 1995, all crude oil was sold under contracts with terms of up to
six months.

  The average realized natural gas price increased from $1.65 per mcf in 1995 to
$1.73 per mcf in 1996.

  Costs and expenses.  1996 operating costs were $2.318 million, compared $0.996
  ------------------                                                            
million in 1995, an increase of 133%. This increase reflects the higher
production volumes resulting from a full year's contribution from Source
Petroleum Inc. and the NAGIT assets.  On a per barrel basis, lease operating
costs decreased, largely due to reductions in fixed costs, mainly field labor.

  Depreciation, which is calculated on a unit of production (boe) basis,
amounted to $1.612 million, reflecting the higher production volumes.  In the
previous year, depletion was included as part of the exceptional write down of
oil and gas interests totaling $14.881 million.

  Exceptional costs arising from irregularities in 1996 were $0.589 million,
which relate primarily to professional fees incurred in connection with the
investigations into the involvement of Mr. O'Brien in the affairs of Alliance,
and are net of the estimated proceeds resulting from the settlement with Mr.
O'Brien. The exceptional costs arising from irregularities in 1995 of $1.787
million reflect the financial loss resulting from a number of transactions
involving Mr. O'Brien or parties now known to have been connected with him.

                                       74
<PAGE>
 
  The general and administrative expenses incurred in 1996 of $2.629 million
(1995 - $1.637 million) include a number of non-recurring items which were
incidental to the investigation into the activities of Mr. O'Brien.

  Loss before and after tax (Net loss).  The loss before and after tax was
  ------------------------------------                                    
$3.593 million in 1996 compared with a loss of $18.213 million in 1995.  The
1995 loss included the exceptional write-down of $14.881 million of oil and gas
assets to the carrying value of Alliance's estimated proved oil and gas reserves
together with the exceptional charge of $1.787 million relating to the loss
arising from transactions with certain companies related to Mr. O'Brien.

  Net interest income increased from net interest payable of $0.114 million in
1995 to net interest receivable of $0.070 million in 1996.  The increase in
interest receivable from $0.049 million in 1995 to $0.257 million in 1996 arose
as the result of higher cash balances following the receipt of $11.7 million
from the placing and open offer in May 1995.  This also enabled Alliance to
substantially reduce its debt and hence reduce bank interest payable from $0.163
million in 1995 to $0.028 million in 1996.

  Exceptional amounts written off investments in 1996 of $0.201 represent
additional charges made to the profit and loss account in respect of costs
incurred in relation to investments written off in the year to 30 April 1995 of
$0.464 million.

  Loss per Existing Alliance Share in 1996 was (0.8)p [($0.01)] compared with
the loss per Existing Alliance Share in 1995 of (8.1)p [$0.13].

1995 COMPARED WITH 1994

  Operating Results.

  Production.  In the year ended April 30, 1995, Alliance's production amounted
to 87,000 boe.  The increase of 102% in Alliance production over 43,000 boe in
the year ended April 30, 1994 was principally due to the inclusion of six
months' contribution from Source Petroleum Inc. (which was acquired by Alliance
on January 25, 1995 with an effective date of November 1, 1994) and four months'
contribution from the producing assets acquired by Alliance from North American
Gas Investment Trust PLC (NAGIT) on April 10, 1995 (effective January 1,  1995).

  All Alliance production came from the US.  Natural gas represented
approximately 45% of total production in 1995 against 35% in 1994.

  Sales.  Total sales increased by 79% from $0.837 million in 1994 to $1.483
  -----                                                                     
million in 1995, reflecting the significant increase in production.  South
Louisiana Sweet crude fluctuated between $15.00 per barrel and over $19.00 per
barrel during the year to April 1995.  Alliance's average crude oil price
realized in 1995 was $16.53 per barrel compared with $16.55 per barrel in  1994.
In 1995 and 1994, all crude oil was sold under contracts with terms of up to six
months.

  The average realized natural gas price decreased from $2.59 per mcf in 1994 to
$1.65 per thousand cubic feet in 1995.

  Costs and expenses.  1995 operating costs were $0.996 million compared with
  ------------------                                                         
$0.521 million in 1994, an increase of 79%.  This increase principally reflects
the higher production volumes resulting from a half year's contribution from
Source Petroleum Inc. and four months from the NAGIT assets.  On a per barrel
basis however, lease operating costs actually decreased, largely due to
reductions in fixed costs, mainly field labor.

  Depletion was included as part of the exceptional write down of oil and gas
interests totaling $14.881 million.  The depletion charge for 1994 was $0.125
million.

  The exceptional costs arising from irregularities in 1995 of $1.787 million
reflect the financial loss resulting from a number of transactions involving Mr.
O'Brien or parties now known to have been connected with him.  No such
exceptional costs were reported in 1994.

  The general and administrative expenses incurred in 1995 of $1.637 million
(1994 - $1.312 million) reflect the increased overheads attributable to the
enlarged group following the acquisition of Source Petroleum Inc.

  Profit before and after tax (Net loss).  The loss before and after tax was
  --------------------------------------                                    
$18.213 million in 1995 compared with a loss of $1.177 million in 1994.  The
1995 loss included the exceptional write-down of $14.881 million of oil and gas
assets to the carrying value of Alliance's estimated proved oil and gas reserves
together with the exceptional charge of $1.787 million relating to loss arising
from transactions with certain companies related to Mr. O'Brien.

  Net interest payable increased from $0.056 million in 1994 to $0.114 million
in 1995, largely reflecting the increase in debt at April 1995.

  Exceptional amounts written off investments in 1995 of $0.464 represent
charges made to the profit and loss account in respect of costs incurred in
relation to investments written off in the year to 30 April 1995. No such
charges were incurred in 1994.

  Loss per Existing Alliance Share in 1995 was (8.1)p [($0.13)] compared with
the loss per Existing Alliance Share in 1994 of (0.01)p [($0.02)].

LIQUIDITY AND CAPITAL RESOURCES

  In the six months to October 31, 1996 cash outflow from operating activities
was $0.529 million compared with an outflow for the comparable period in 1995 of
$4.776 million. In the six months to October 31, 1995 a portion of the proceeds
to the placing and open offer was used to reduce operating creditors by almost
$2.3 million.

  In 1996 cash outflow from operating activities was $5.399 million compared
with an inflow in 1995 of $1.987 million. In 1996 a portion of the proceeds from
the placing and open offer was used to reduce operating creditors by almost $3.5
million.  By comparison, in the year ended April 1995, operating creditors had
increased by $4.7 million.

  Cash outflow in the six months to October 31, 1995 and in the year to April
30, 1996 also increased due to high professional fees incurred in connection
with the investigation into the affairs of Mr. O'Brien and overall, general and
administrative expenses increased due to a number of non-recurring items which
were incidental to the O'Brien investigation. The net outflow on investing
activities was $2.512 million in 1996 compared with $4.045 million in 1995.

  Capital expenditures in the six months to October 31, 1996 were $0.114
million compared with $1.509 million in the comparable period in 1995 reflecting
the low level of both drilling activity and acquisitions in the current  period.

  Capital expenditures in 1996 were $1.672 million compared with $8.533 million
in 1995 (1994 - $4.006 million).  Of the $8.533 million, $2.264 million related
to the acquisition of Source Petroleum Inc. and $3.080 million related to the
purchase of a portfolio of producing properties located in the US from NAGIT.
In addition, the Valentine well was drilled and costs associated with the
Valentine well were capitalized amounting to $1.838 million.  Following the
completion of the investigation into the affairs of Mr. O'Brien, $1.685 million
of the $1.838 million was identified as a loss arising from transactions with
certain companies related to Mr. O'Brien and accordingly reclassified.  The
capital expenditure in 1996 included the drilling of three wells, one of which,
in part of the South Elton field, was successful and contributed significantly
to the uplift in reserves.

  At April 1995, Alliance had capital commitments amounting to $5.300 million
(1994 - $6.037 million). At April 1996, Alliance had no capital commitments.

  At April 1995, Alliance had total borrowings of $3.962 million (1994 - $1.692
million) and after deduction of cash, net borrowings of $3.898 million (1994 -
$1.404 million).  In May 1995, Alliance raised $11.700 million (net) by way of a
placing and open offer and at April 1996 Alliance had reduced its debt to $0.134
million giving a net cash position of $1.043 million.  In the six months to
October 31, 1996, Alliance raised net proceeds of $2.227 million from the
disposal of various non-operated predominantly gas producing properties. At
October 31, 1996 Alliance had debt of $0.104 million giving a net cash position
of $2.411 million.

  Alliance currently plans to increase capital expenditures to approximately
$2.7 million in fiscal 1997 principally for remedial and developmental capital
expenditures for the combined company's assets in Alabama, Mississippi and
Louisiana. Management believes that, after debt service, it will have sufficient
cash provided by operating activities, availability under the Alliance Credit
Agreement, and asset sales to fund planned capital expenditures in 1997.  Cash

                                       76
<PAGE>
 
from operating activities is anticipated to provide sufficient funds to meet
debt service requirements under the Alliance Credit Agreement. See "Alliance--
Financing." In addition, based on its knowledge of the market for oil and gas
properties and its recent property sales, Alliance believes that it will be able
to sell certain non-strategic properties for up to $4.8 million during calendar
1997. Alliance intends to use the proceeds of these sales to reinvest in the
purchase and development of non-producing properties and to reduce negative
working capital.  Similarly, based on anticipated revenues from the proved
developed oil and gas properties of the combined company as reflected in the
reserve reports for Alliance and LaTex, management of Alliance believes that
cash generated from operating activities will provide sufficient funds to meet
debt service requirements and fund planned capital expenditures through at least
April 30, 1999. Substantially all of Alliance's capital expenditures are
discretionary until shortly before being made and, therefore, permit flexibility
in planning. There can be no assurance, however, that the cash will be available
as anticipated or that the capital expenditures will be successfully made.
Alliance has also agreed in principle with the Bank to acquire from the Bank an
overriding royalty interest (the "ORRI") held by the Bank in certain oil and gas
properties in which LaTex has as ownership interest.

  Impact of Inflation and Changing Prices. The business of Alliance is not
seasonal but is sensitive to crude oil and natural gas pricing, margins between
crude oil and refined products, and chemical margins. Inflation impacts Alliance
by increasing costs of labor and suppliers, and increasing costs of acquiring
and replacing property, plant and equipment.  The replacement cost of property,
plant and equipment is generally greater than the historical cost as a result of
inflation.

_____________
(1) All options reflected in this table expired on the removal or resignation of
    the option holder during fiscal 1996.

  Director Compensation. The compensation of the non-executive directors is
reviewed by the board of directors from time to time to ensure that this
compensation is in line with current market practice. Under Alliance's Articles
of Association, shareholders determine the maximum aggregate amount payable by
way of fees to directors and this maximum amount is currently fixed at
(Pounds)100,000 per year.  During 1996, the following directors were paid the
indicated fees for their services as directors: Mr. Douglas $30,012, Mr. Kennedy
$10,504, Mr. Roberts $2,626, and Mr. Jones 

                                       80
<PAGE>
 
$2,626. In addition, Mr. Kennedy was awarded $52,764 for his executive services
as chairman of the management committee from September 4, 1995.

  Management Employment Agreements. Each of Messrs. Keenan, Williams and
Fenemore have entered into Executive Service Agreements with Alliance providing
for his employment in his current capacity for an initial fixed term of two
years beginning October 15, 1996, December 16, 1996, and September 20, 1996,
respectively, and automatic extensions of the initial term for additional one
year periods unless written notice of either party's intention not to extend has
been given to the other party at least three months prior to the expiration of
the then effective one year period of employment, provided that the executive
may at any time terminate his employment by giving a minimum of three months
notice. If the executive's employment terminates for any reason other than the
executive's breach of the agreement, disability or malfeasance, Alliance must
pay the executive an amount equal to the executive's salary for the then
remaining term of the executive's employment. Upon the involuntary termination
of the executive's employment without cause or voluntary termination by the
executive after a change in his office location, his responsibilities or
reduction in compensation following a change in control of Alliance, the
executive is entitled to the payment in one lump sum of cash in an amount equal
to two times the average annual salary, bonus and benefits paid to the executive
for the previous two years.

  The annual salary under the agreements is $160,000 for Mr. Keenan,
(Pounds)85,000 for Mr. Williams, and (Pounds)96,000 for Mr. Fenemore, plus any
bonuses or other compensation determined by Alliance's Board of Directors in its
discretion. The agreements also provide for the grant of stock options at an
exercise price of 2p per share for 6,000,000 Existing Alliance Shares for Mr.
Keenan, 2,500,000 Existing Alliance Shares for Mr. Williams, and 1,000,000
Existing Alliance Shares for Mr. Fenemore.

  Stock Option Plans.  Alliance has two stock option plans in existence. Both
plans are administered by the remuneration committee of the Board of Directors
(the "Committee").  All directors are employees of Alliance and any other
company of which Alliance has control, as well as consultants to any director or
employee of the consultants to Alliance who does not give less than 20 hours per
week to his duties with Alliance, are eligible to receive awards under the
plans.  The exercise price of options granted under the plans are determined by
the Committee, but may not be less than the higher of the nominal value of the
shares and the market value of the shares on the London Stock Exchange. Options
may be awarded during the six weeks following the announcement of Alliance's
final or interim results for any financial period and are not transferrable or
assignable.  No option may be granted if, as a result, the total number of
shares issuable in respect of options granted within the ten years or the three
years preceding the date of grant would exceed 10% or 3%, respectively, of
Alliance's issued ordinary share capital on that date.  No option may be granted
to an eligible employee within two years before his normal retirement date, and
the total market value of shares subject to options granted to an individual,
when taken together with the total market value of any other shares the
individual has acquired or may acquire on the exercise of options granted within
the previous 10 years, generally may not exceed four times the individual's cash
earnings from Alliance (or preceding tax year, whichever is greater).  Options
granted under the plans may become exercisable beginning three years after the
date of the grant, and must be exercised before the 10th anniversary of the date
of the grant.


                        DESCRIPTION OF ALLIANCE SHARES

  The authorized capital stock of Alliance consists of 465,000,000 ordinary
shares of (Pounds)0.01 each. Upon completion of the Merger, the authorized
capital stock will consist of 46,000,000 New Alliance Shares of (Pounds)0.40
each, of which 29,552,603 shares will be outstanding if only the Merger is
completed, or 31,052,603 shares will be outstanding if both the Merger and the
acquisition of the ORRI are completed. The following sections include certain
information concerning such shares, based on English law and a summary of
certain provisions of the Memorandum and Articles of Association of Alliance.
This information and summary do not purport to be complete and are qualified in
their entirety by reference to the full Memorandum and Articles of Association,
copies of which have been filed as exhibits to the Registration Statement of
which this Proxy Statement forms a part. The description below reflects an
amendment to the Articles of Association that is to be adopted concurrently with
the completion of the Merger. LaTex shareholders should also review "The Merger
- - Summary Comparison of LaTex Common Stock and New Alliance Shares."

  All of the 324,152,640 issued and outstanding Existing Alliance Shares are
fully paid or credited as fully paid and not subject to calls for additional
payments of any kind.  The Existing Alliance Shares are, and the New Alliance
Shares will be, issued in registered form.

                                       81

DIVIDENDS

  Holders of Alliance Shares are entitled to receive such dividends as may be
declared by the board of directors.  To date there have been no dividends paid
to holders of Alliance Shares.

OPTIONS

  In addition to options granted to management, see "Alliance - Management -
Executive Compensation," and the warrants to be issued in the Merger, see "The
Merger - Registration and Resale," by an agreement dated March 31, 1994,
Alliance granted to John Duncan and Co Limited an option to subscribe for
2,000,000 Existing Alliance Shares at 7.5p per share in consideration for
professional services. The option is exercisable in whole or in part at any time
from January 1, 1996 up to and including December 31, 2001.

LIQUIDATION RIGHTS

  On a liquidation, the court-appointed liquidator may (with the sanction of an
extraordinary resolution) divide amongst the holders of the Alliance shares the
whole or any part of the assets of Alliance and may, for such purpose, set such
values as he deems fair upon any property to be divided and may determine how
such division shall be carried out as between the shareholders.

VOTING RIGHTS

  Voting at any general meeting of shareholders is by a show of hands unless a
poll is duly demanded. A poll may be demanded by (i) the chairman of the
meeting, (ii) at least three shareholders entitled to vote at the meeting, (iii)
any shareholder or shareholders representing in the aggregate not less than one-
tenth of the total voting rights of all shareholders entitled to vote at the
meeting or (iv) any shareholder or shareholders holding shares conferring a
right to vote at the meeting on which there have been paid up sums in the
aggregate equal to not less than one-tenth of the total sum paid up on all the
shares conferring that right.

  On a show of hands, every shareholder who (being an individual) is present in
person (or being a corporation) is present by a duly authorized representative
at a shareholders meeting of Alliance and entitled to vote will have one vote,
and on a poll, every shareholder who is present in person or by proxy shall have
one vote per share.  The necessary quorum for a shareholders' meeting shall be a
minimum of two persons (each of whom is a shareholder or proxy).

  If all the members entitled to vote at a general meeting sign written
resolutions in lieu of a vote at such meeting, such resolutions shall be valid
and effective as resolutions passed at a general meeting.

  Unless otherwise required by law or the Alliance's Articles of Association,
voting in a general meeting is by ordinary resolution (e.g., resolutions for the
election of directors, the approval of financial statements, the declaration of
final dividends, the appointment of auditors, the increase of authorized share
capital or the grant of authority to allot shares).  An ordinary resolution
requires the affirmative vote of a majority of the votes of those persons
present at a meeting at which there is a quorum.  A special resolution (e.g.,
modifying the rights of any class of shares at a meeting concerning an
alteration of Alliance's Memorandum or Articles of Association or a winding-up
of Alliance) or an extraordinary resolution requires the affirmative vote of not
less than three-fourths of the eligible votes.  Meetings are generally convened
upon advance notice of 21 or 14 days (not including the days of delivery or
receipt of the notice) depending on the nature of the business to be transacted.

  For as long as a Regulated Entity or its affiliate is a holder of New Alliance
Shares, it will not be entitled to vote more than 5% of the total votes normally
exercisable by holders of New Alliance Shares.  Upon a transfer of any New
Alliance Shares to a Regulated Entity, this restriction will cease to apply to
those New Alliance Shares.

PRE-EMPTIVE RIGHTS

  The Companies Act of 1985, as amended (the "Companies Act") confers upon
shareholders, to the extent not disapplied, rights of pre-emption in respect of
the allotment of equity securities that are or are to be paid up wholly in cash.
These provisions may be disapplied by a special resolution of the shareholders,
either generally or specifically, for 

                                       82
<PAGE>
 
a period not exceeding five years. Additionally, the Articles of Association of
Alliance provide the shareholders with such a pre-emptive right unless Alliance
shall by special resolution otherwise direct.

VARIATION OF RIGHTS

  If at any time the share capital of Alliance is divided into different classes
of shares, the rights attached to any class may be varied or abrogated, subject
to the provisions of the Companies Act, with the written consent of the holders
of not less than three-quarters of  the issued shares of the class, or with the
sanction of any extraordinary resolution passed at a separate meeting of the
holders of the shares of that class.  At every such separate meeting, the quorum
shall be members of the class present in person or by proxy holding not less
than one-third of the issued shares of the class, or at an adjourned meeting of
such holders as described above a quorum will be established if any one person
entitled to vote at the meeting (or his proxy) is present.  Each holder of
shares of the class shall have one vote in respect of every share of the class
held by such person.

DISCLOSURE OF INTERESTS

  Under the Companies Act, any person who acquires (alone or, in certain
circumstances, with others) an interest in the relevant share capital of
Alliance in excess of the "notifiable percentage" (currently three percent)
comes under an obligation to disclose prescribed information to Alliance in
respect of those shares. After the "notifiable" level is exceeded, similar
notifications must be made, in respect of the whole percentage figure increases
or decreases, rounding down to the next whole number.

  In addition, the Companies Act gives Alliance power to require persons who it
knows are, or has reasonable cause to believe to be, or to have been within the
previous three years, interested in its relevant share capital to disclose
prescribed particulars of those interests.  Failure to supply the information
required may lead to disenfranchisement of the relevant shares and a prohibition
on their transfer and on dividend or other payments in respect of them.

  In this context, the term "interest" is broadly defined and will generally
include an interest of any kind in shares.

EXCHANGE CONTROLS AND OTHER LIMITATIONS AFFECTING SECURITY HOLDERS

  There are currently no U.K. foreign exchange controls on the payment of
dividends on the Existing or New Alliance Shares or the conduct of Alliance's
operations.  There are no restrictions under Alliance's Memorandum and Articles
of Association or under English law that limit the right of non-resident or
foreign owners to hold or vote Existing or New Alliance Shares.


                          MATERIAL TAX CONSIDERATIONS

  The following discussion is a summary of the material U.S. federal income tax
consequences of the Merger and the material U.S. federal income tax and U.K. tax
consequences of ownership and disposition of the New Alliance Shares. However,
it is not intended to be a complete discussion of all potential tax effects that
might be relevant to the Merger or the ownership or disposition of the New
Alliance Shares.

  This summary deals only with citizens or residents of the United States or
domestic corporations (each a "U.S. Holder"). It may not be applicable to
certain classes of taxpayers, including, U.S. Holders who are residents (or, in
the case of an individual, resident or ordinarily resident) for U.K. tax
purposes in the U.K. or who carry on business in the U.K. through a branch or
agency, insurance companies, tax-exempt organizations, financial institutions,
securities dealers, broker-dealers, foreign persons and persons who acquired
LaTex Shares pursuant to an exercise of employee stock options or rights or
otherwise as compensation.  These classes of taxpayers should consult their own
tax advisors regarding the specific tax consequences of the Merger and the
ownership and disposition of the New Alliance Shares.  Moreover, the state,
local and foreign (other than certain U.K.) tax consequences of the Merger and
the ownership and disposition of New Alliance Shares are not discussed below.

  This summary is based on laws, regulations, rulings, practice and judicial
decisions in effect at the date of this Proxy Statement.  Legislative,
regulatory or interpretive changes, future court decisions or specific tax
treaty provisions may 

                                       83
<PAGE>
 
significantly modify the statements made in this description. Any such changes
or interpretations may or may not be retroactive and could affect the tax
consequences described herein. EACH SHAREHOLDER IS URGED TO CONSULT WITH THE
SHAREHOLDER'S OWN TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO THE
HOLDER OF THE TRANSACTIONS DISCUSSED IN THIS SECTION, INCLUDING THE
APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND OF CHANGE
IN APPLICABLE TAX LAWS.

  Except as otherwise indicated, statements of legal conclusions regarding
United States' tax treatment, tax effect or tax consequences are the opinions of
Jenkens & Gilchrist, a Professional Corporation, United States counsel for
Alliance, based on the Internal Revenue Code of 1986 (the "Code") and applicable
regulations thereunder, each as amended and in effect on the date of this Proxy
Statement and on reported judicial decisions and published positions of the
Internal Revenue Service ("IRS"). No rulings have been requested from the IRS
concerning any of the matters described in this Proxy Statement. In some cases,
particularly those as to which tax counsel's opinion is qualified, there is a
risk that the IRS and the courts will disagree with the conclusions of tax
counsel and no assurance can be given that the tax opinions will be followed by
the courts if challenged.

  Except as otherwise indicated, statements of the legal conclusion regarding
United Kingdom tax treatment, tax effect or tax consequences are the opinions of
Ashurst Morris Crisp, United Kingdom counsel for Alliance, based on United
Kingdom law and current Internal Revenue practice, as in effect of this Proxy
Statement and on reported judicial decisions and published positions of the
Inland Revenue ("UKIR"). No rulings have been requested from the UKIR regarding
any of the matters described in this Proxy Statement. In some cases,
particularly those as to which tax counsel's opinion is qualified, there is a
risk that the UKIR will disagree with the conclusions of tax counsel.

  The laws, regulations, administrative rulings and judicial decisions that form
the basis for conclusions with respect to the tax consequences of the Merger are
very complex and are subject to change at any time. Accordingly, each LaTex
shareholder is urged to consult his own tax advisor as to the consequences to
him of the Merger. The tax opinions of Jenkens & Gilchrist, a Professional
Corporation and Ashurst Morris Crisp are filed as exhibits to the Registration
Statement on Form F-4 filed with the SEC, of which this Proxy Statement
constitutes a part. The tax opinions are not filed as appendices to the Proxy
Statement. Upon receipt of a written request by a LaTex shareholder (or his
representative who has been so designated in writing) to Alliance Resources PLC,
One Houston Center, 1221 McKinney, Suite 1814, Houston, Texas 77010, a copy of
the tax opinions will be transmitted promptly, without charge, by Alliance.

U.S. TAX CONSEQUENCES OF THE MERGER

  Recognition of Gain.  While the Merger qualifies as a reorganization within
the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Internal Revenue
Code of 1986, as amended (the "Code"), because Alliance is a foreign corporation
and the New Alliance Shares to be issued to the U.S. Holders of LaTex Shares are
anticipated to represent more than 50% of the outstanding stock of Alliance
after the Merger, U.S. Holders must recognize any gain realized on the surrender
of LaTex Shares or a LaTex Warrant pursuant to the Merger (such a share or
warrant is referred to as a "Gain LaTex Share").  The amount of gain recognized
with respect to a Gain LaTex Share will be equal to the excess, if any, of (i)
the fair market value immediately after the Merger of the New Alliance Shares
received for the Gain LaTex Share, over (ii) the U.S. Holder's tax basis in the
Gain LaTex Share. Any gain recognized should be long-term capital gain, provided
the Gain LaTex Share was a capital asset in the hands of the U.S. Holder and had
been held for more than the then applicable long-term holding period (currently
one year). A U.S. Holder will have a tax basis in each New Alliance Share
received for the Gain LaTex Share equal to the fair market value of the New
Alliance Share immediately after the Merger. The holding period of each New
Alliance Share received in exchange for a Gain LaTex Share will begin as of the
Effective Time of the Merger. To the extent a U.S. Holder holds LaTex Shares
subject to a substantial risk of forfeiture, the U.S. Holder will recognize
ordinary income at the time the substantial risk of forfeiture lapses, equal to
(i) the then fair market value of the LaTex Shares or the New Alliance Shares
received in exchange therefor, as the case may be, over (ii) the U.S. Holder's
tax basis in the LaTex Shares or such New Alliance Shares, as the case may be.

  Nonrecognition of Loss.  U.S. Holders will not be entitled to recognize any
loss realized on the surrender of LaTex Shares or LaTex Warrant pursuant to the
Merger (such a share or warrant referred to as a "Loss LaTex Share").  U.S.
Holders surrendering both Gain LaTex Shares and Loss LaTex Shares will not be
entitled to offset the gains recognized on the Gain LaTex Shares with the losses
realized on the Loss LaTex Shares. A U.S. Holder will have an aggregate tax
basis in the New Alliance Shares received for the U.S. Holder's Loss LaTex
Shares equal to such U.S. Holder's aggregate 

                                       84
<PAGE>
 
tax basis in the Loss LaTex Shares. The holding period of the New Alliance
Shares will include the holding period of the Loss LaTex Shares. U.S. Holders
should consult their own tax advisors as to the determination of their tax basis
and holding period in any New Alliance Share.

   Information Reporting.  Since Alliance is a foreign corporation, U.S. Holders
of LaTex Shares and LaTex Warrants may be required to complete, execute and file
IRS Form 926 with such Holder's U.S. federal income tax return for the year in
which the Effective Time of the Merger occurs. Failure to comply with these
reporting requirements may subject a U.S. Holder to a penalty equal to 25% of
the gain realized by the U.S. Holder as a result of the Merger, and the statute
of limitations for assessing tax on arising from the Merger will not begin to
run until the holder is in compliance with reporting requirement.  U.S. Holders
should consult their tax advisors regarding the U.S. information reporting
requirements as a result of the Merger.

UK AND US TAX CONSEQUENCES OF OWNERSHIP AND DISPOSITION OF NEW ALLIANCE SHARES

   TAXATION OF DIVIDENDS

   U.K. Taxation.  Alliance does not expect to pay dividends for the foreseeable
future.  Should Alliance begin paying dividends, it will be required when paying
a cash dividend with respect to its New Alliance Shares to pay to the U.K.
Inland Revenue a payment known as Advance Corporation Tax ("ACT"). The current
rate of ACT is 25% of the net dividend paid to a holder of New Alliance Shares.
An amount equivalent to the amount of the ACT paid in this way is, under current
English law, normally allowed as a credit against the U.K. tax liability of
holders of New Alliance Shares who are residents of the United Kingdom.

   A U.S. Holder will generally be entitled, under the current Convention
between the U.S. and the U.K. for the Avoidance of Double Taxation and the
Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital Gain
(the "Income Tax Convention") and current U.K. law as applied by the U.K. Inland
Revenue, to receive from the U.K. Inland Revenue, in addition to any dividend
paid by Alliance, an amount in the nature of a tax refund (an "ACT Refund")
equal to the ACT in respect of the dividend, less a U.K. withholding tax of 15%
of the sum of the dividend and the related ACT. Thus, assuming continuance of
the ACT at a rate of 25%, a net dividend paid to a U.S. holder of (Pounds)8
(chosen for illustrative purposes only) will entitle the U.S. Holder described
above to receive, in addition to the dividend and upon compliance with the
refund procedures described below, an ACT Refund of (Pounds)0.5 calculated by
reducing the ACT of (Pounds)2 by a withholding tax of (Pounds)1.5. Special rules
may apply to certain U.S. Holders, including, without limitation, certain
domestic corporations, partnerships, trusts, estates, residents of the U.K. and
domestic corporations owning, actually or constructively, 10% or more of the
voting stock of Alliance.

   A U.S. Holder who is entitled to the ACT Refund may, subject to agreement
with the U.K. Inland Revenue, receive payment in respect of the ACT Refund at
the same time as and together with a payment of the dividend. In order to do so,
a U.S. Holder must have his New Alliance Shares registered in the name of a
nominee approved by the U.K. Inland Revenue for the purpose, and the nominee
must follow certain procedural requirements. A U.S. Holder must provide the name
of his or her nominee in order to participate in this arrangement. In addition,
the U.S. Holder must be either:

1. An individual who (a) is not resident in the U.K.; (b) has not during the
   previous four years been in the U.K. for as much as three months a year on
   average, or for a period or periods amounting in all to six months in the
   U.K. income tax year to which the claim on his behalf relates; (c) has not
   been absent from the U.S. for a complete U.S. tax year in any of the previous
   four years; (d) does not have a permanent establishment in the U.K.; (e) does
   not perform professional/personal services from a fixed base in the U.K. and
   (f) does not own 10% or more of the class of shares in respect of which the
   dividend is paid; or

2. A corporation (a) which is managed and controlled in the U.S. and does not
   have a permanent establishment in the U.K.; (b) which does not own 10% or
   more of the class of shares in respect of which the dividend is paid; (c)
   which does not, alone or together with one or more associated corporations,
   control, directly or indirectly, 10% of the voting power of Alliance; (d)
   which is liable to U.S. tax on the dividend and (e) at least 75% of the
   capital of which is owned directly or indirectly by persons who are U.S.
   residents.

                                       85
<PAGE>
 
  These arrangements will be extended to trusts, estates in the course of
administration, pension funds, foundations and similar bodies only with the
prior approval of the U.K. Inland Revenue.  These arrangements can be restricted
without notice by the U.K. Inland Revenue.

  U.S. Holders who wish to receive an ACT Refund but do not qualify to receive
the ACT Refund directly under the U.K. Inland Revenue arrangements should
consult their tax advisers on their eligibility to receive and the procedures to
obtain an ACT Refund.

  The U.K. Finance Act 1994 contains certain provisions allowing companies to
elect to pay a foreign income dividend ("FID") to which special rules apply and,
in particular, which does not carry any tax credit. Alliance has no present
intention of electing to pay any dividends under the FID scheme and the above
applies only to dividends not paid under the scheme.

  U.S. Taxation.  A U.S. Holder will realize dividend income for U.S. federal
income tax purposes in an amount equal to the sum of any dividend paid by
Alliance, amounts paid in respect of the related refund of ACT and the amount of
any U.K. withholding tax thereon, to the extent paid out of the current or
accumulated earnings and profits of Alliance, as determined under current U.S.
federal income tax principles. The amount included in income to a U.S. Holder
will be the U.S. dollar value of the payment (determined at the spot rate on the
date of such payment) regardless of whether the payment is in fact converted
into U.S. dollars.  Generally, any gain or loss resulting from currency exchange
fluctuations during the period between the date of such payment and the date the
dividend payment is converted into U.S. dollars will be treated as ordinary
income or loss.  Dividends paid to a U.S. Holder will generally not be eligible
for the dividends received deduction allowed to corporations under the Code.

  Subject to certain limitations, the U.K. withholding tax will be treated as a
foreign income tax that may be claimed as a deduction from taxable income or as
a credit against the U.S. federal income tax liability of the U.S. Holder. The
particular circumstances of each U.S. Holder will affect his ability to use the
foreign tax credit.  U.S. Holders should consult their own tax advisor about the
availability and computation of the foreign tax credit.


  BACKUP WITHHOLDING AND INFORMATION REPORTING

  A U.S. Holder may, under certain circumstances, be subject to certain
information reporting requirements with respect to dividends paid on the New
Alliance Shares (but currently not backup withholding, although the issue of
whether backup withholding should apply in those circumstances, where
information reporting is required is under consideration by the IRS).

  TAXATION OF CAPITAL GAINS

  Upon the sale or exchange of a New Alliance Share, a U.S. Holder will
recognize a gain or loss for U.S. federal income tax purposes in an amount equal
to the difference between the amount realized and the U.S. Holder's tax basis in
the New Alliance Share.  Such gain or loss will be a capital gain or loss if the
New Alliance Share was a capital asset in the hands of the U.S. Holder and will
be a long-term capital gain or loss if the New Alliance Share has been held for
more than one year on the date of the sale or exchange.  The deductibility of
capital losses is subject to limitations.

  A U.S. Holder that is not resident (or, in the case of an individual, not
resident or ordinarily resident) in the U.K. will not normally be liable for
U.K. taxation on capital gains realized on the sale of such Holder's New
Alliance Shares or on the sale of New Alliance Shares acquired pursuant to a
U.S. Holder's exercise of New Warrants, Bank Warrants or on any disposal of the
New Warrants or Bank Warrants unless such U.S. Holder carries on a trade in the
U.K. through a branch or agency and such New Alliance Shares or such Alliance
warrants are or have been used, held or acquired by or for the purposes of such
trade, branch or agency or used in or for the purpose of such trade.

  A U.S. citizen who is resident or ordinarily resident in the U.K., a U.S.
corporation that is resident in the U.K. because its business is managed or
controlled there or a U.S. citizen who, or a U.S. corporation that, carries on a
trade or business through a permanent establishment in the U.K. and that
acquires or holds a New Alliance Share or Alliance warrant in connection with
that permanent establishment may be subject to both U.S. and U.K. tax on its
capital gains upon disposition of the New Alliance Share or Alliance warrant.
Subject to certain limitations, however, the U.S. tax laws 

                                       86
<PAGE>
 
would permit a tax credit against U.S. federal income tax liability in the
amount of any U.K. tax (namely, capital in the case of an individual and
corporation tax on chargeable gains in the case of a corporation) that has been
paid in respect of such gain.

   ESTATE AND GIFT TAX

   Under the U.S.-U.K. double taxation convention relating to estate and gift
taxes (the "Estate and Gift Tax Convention"), a New Alliance Share held by an
individual who is domiciled in the U.S. and is not a national of the U.K. will
not be subject to U.K. Inheritance Tax on the individual's death or on a
transfer of the New Alliance Share in trust by a settlor not domiciled in the
U.S. and in the exceptional case where the New Alliance Share is part of the
business property of a U.K. permanent establishment of an enterprise or pertains
to a U.K. fixed base of an individual used for the performance of independent
personal services. The Estate and Gift Tax Convention generally provides a
credit for the amount of any tax paid in the U.K. against the U.S. federal tax
liability in a case where the New Alliance Share is subject both to U.K.
Inheritance Tax and to U.S. federal estate and gift tax.

   STAMP DUTY AND STAMP DUTY RESERVE TAX

   No U.K. stamp duty or stamp duty reserve tax ("SDRT") will be payable on the
issuance of the New Alliance Shares, nor in practice will U.K. stamp duty or
SDRT be payable on the issuance of Alliance warrants.

   Under current U.K. law, the transfer of New Alliance Shares or Alliance
warrants will generally give rise to a liability to U.K. stamp duty, normally at
the rate of 50p for every (Pounds)100 (or part thereof) of the actual
consideration paid. Where there is no stamped document recording the sale of the
shares, a charge to SDRT, also at the rate of 0.5%, arises. Provided that the
transfer is executed and stamped within six years of the unconditional contract
to sell, any obligation to pay SDRT is canceled and any SDRT paid is refundable.

   Special rules apply in relation to depository receipt arrangements and
clearance services.

   Section 186 of the Finance Act 1996 provides that there is to be no liability
for stamp duty on the transfer of shares into CREST, the paperless trading
system that started in July 1996.  SDRT is to be chargeable immediately on
entering into an unconditional agreement to transfer shares at the rate of 0.5%
of the actual consideration paid (which SDRT is to be canceled or repaid if the
agreement is completed by a duly stamped transfer).  Subsequent transfers of
shares within CREST will not give rise to a liability to stamp duty, as there
will be no stampable document.

   CONTROLLED FOREIGN CORPORATION STATUS

   Under Subpart F of the Code, a controlled foreign corporation ("CFC") is a
foreign corporation that on any day of its taxable year is owned directly,
indirectly or by attribution more than 50%, by vote or value, by "United States
Shareholders." For this purpose, a United States Shareholder is a United States
person who owns directly, indirectly or by attribution at least 10% of the total
combined voting power of all shares entitled to vote of the foreign corporation.
Alliance has represented that it is currently not a CFC and it is not
anticipated to be a CFC immediately after the Merger.

   In the event Alliance becomes a CFC for an uninterrupted period of at least
30 days during a taxable year, a United States Shareholder of Alliance must
include in income for his taxable year in which or with which the taxable year
of Alliance ends his pro rata share of certain types of undistributed income of
Alliance (primarily subpart F income and increase in earnings invested in U.S.
property). A U.S. person who owns directly, indirectly or by attribution less
than 10% of the total combined voting power of all classes of stock of Alliance
entitled to vote would not be taxed on the undistributed income of Alliance.
Such a U.S. person would be taxed under the ordinary rules relating to the
taxation of corporate distributions as discussed above.

   U.S. Holders should consult their tax advisors as to the applicable law in
any year in which Alliance is a CFC.

   PASSIVE FOREIGN INVESTMENT COMPANY STATUS

   Because Alliance will receive passive income, including interest income and
royalties, Alliance may be classified as a Passive Foreign Investment Company
("PFIC") for U.S. federal income tax purposes. Under current rules, Alliance

                                       87
<PAGE>
 
will be a PFIC if either 75% or more of its gross income in a tax year is
passive income or the average percentage of its assets (by value) that produce
or are held for the production of passive income is at least 50%.  The
determination whether a foreign corporation is a PFIC is made on a year-by-year
basis.  A foreign corporation's status as a PFIC for one year, however, may
affect the shareholders even though the foreign corporation does not meet the
PFIC definition for all other years.

  For purpose of the PFIC tests, if a foreign corporation owns directly or
indirectly at least 25% by value of the stock of another corporation, the
foreign corporation is treated as owning its proportionate share of the assets
of the other corporation, and as if it had received directly its proportionate
share of the income of such other corporation.  Because Alliance will own 100%
of the stock of LaTex after the Merger, Alliance will be treated as owning all
of LaTex's assets and receiving directly all of LaTex's income for purposes of
the PFIC tests.

  If Alliance were to be treated as a PFIC, a U.S. Holder of New Alliance Shares
would be subject to an interest charge on taxes deemed deferred by such U.S.
Holder on receipt of certain "excess" dividend distributions by Alliance to the
U.S. Holder and on recognition of gain on disposition of any New Alliance Shares
of the U.S. Holder (which distributions and gains would generally be allocated
ratably to all days in the U.S. Holder's holding period for such New Alliance
Shares, with the portion so allocated to prior years treated as ordinary income
subject to tax at the highest marginal rate applicable in such prior years).
Alternatively, a U.S. Holder could avoid such interest charge and adverse tax
consequences if Alliance were to agree to comply with certain reporting
requirements, and the U.S. Holder were to elect (a "qualified election") to be
currently taxable on such U.S. Holder's pro rata share of Alliance's earnings
and profits (excluding net capital gain) and net capital gain for each year (at
ordinary and long-term capital gain rates, respectively), even if no
distributions were received. U.S. Holders who make a qualified election may make
an additional election (the "deferral election") to defer payment of the tax
liability on such current income inclusion until the receipt of distributions
from Alliance of the amounts deemed included in the U.S. Holder's income
pursuant to the qualified election. However, a U.S. Holder who makes a deferral
election must pay interest on the deferred tax liability.


  Qualified elections are made on a shareholder-by-shareholder basis.  A U.S.
Holder may make a qualified election for any taxable year at any time on or
before the due date for filing his U.S. federal income tax return for the
taxable year for which the election is made.  A U.S. Holder makes the qualified
election by attaching the shareholder election statement, the PFIC annual
information statement and IRS Form 8621 to such U.S. Holder's timely filed U.S.
federal income tax return and sending a copy of the shareholder election
statement to the Internal Revenue Service Center at P.O. Box 21086,
Philadelphia, Pennsylvania 19114.  Once made, the qualified election applies to
all subsequent taxable years of the U.S. Holder with respect to Alliance unless
revoked by the U.S. Holder with the consent of the IRS.  Alliance will supply
the PFIC annual information statement required to make a qualified election to
any shareholder or former shareholder who requests it and to all shareholders of
record at any time in any PFIC year.

  The deferral election is also made on a shareholder-by-shareholder basis. The
deferral election is made on a year-to-year basis with respect to each year's
tax liability and can be made only by those U.S. Holders who own New Alliance
Shares at the end of Alliance's taxable year to which such tax liability is
attributable.  A U.S. Holder may make a deferral election for any taxable year
by attaching IRS Form 8621 or a similar statement with the U.S. Holder's timely
filed U.S. federal income for the taxable year for which the election is made
and sending a copy of the IRS Form 8621 or similar statement to the Internal
Revenue Service Center at P.O. Box 21086, Philadelphia, Pennsylvania 19114.

  U.S. Holders should consult with their own tax advisors to decide whether and
how to make the qualified and deferral elections.

  If the qualified election is made, a shareholder may recognize foreign
currency gain or loss, if any, at the time it received an actual distribution
from Alliance with respect to income previously included.

  U.S. Holders should consult their tax advisors as to the applicable law in any
year in which Alliance is a PFIC.

  THE SUMMARY OF U.S. AND U.K. TAX CONSEQUENCES SET FORTH ABOVE IS BASED ON THE
INCOME TAX CONVENTION AND ESTATE TAX CONVENTION, U.S. LAW, U.K. LAW AND U.K.
INLAND REVENUE PRACTICE, ALL AS THEY EXIST AS OF THE DATE OF THIS PROXY
STATEMENT.  THIS SUMMARY DOES NOT DISCUSS ALL ASPECTS THAT MAY BE RELEVANT TO
HOLDERS OF NEW

ALLIANCE SHARES IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES. IN PARTICULAR, IT
DOES NOT ADDRESS THE CONSEQUENCES TO HOLDERS OF NEW ALLIANCE SHARES RESIDENT OR
DOMICILED IN THE U.K. OR DOING BUSINESS IN THE U.K. HOLDERS OF NEW ALLIANCE
SHARES ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX
CONSEQUENCES TO THEM OF THE MERGER AND THE OWNERSHIP AND DISPOSITION OF NEW
ALLIANCE SHARES.


               CERTAIN LONDON STOCK EXCHANGE LISTING REQUIREMENTS

  In addition to the provisions of its Articles of Association and the Companies
Act, Alliance is subject to the listing rules of the London Stock Exchange
("LSE") made under Section 142 of the Financial Services Act and, in particular,
to the continuing obligations under those rules.  These require a listed company
to provide to its shareholders any information necessary to enable them and the
public to appraise the position of the company and to avoid the creation of a
false market in its listed securities.  The listed company must ensure equality
of treatments for all shareholders who are in the same position and, where the
securities are listed on more than one stock exchange, must ensure that
equivalent information is made available to the market on each exchange on which
its securities are listed.  In addition, the listing rules impose obligations on
listed companies to send the following information to shareholders:

  1. audited annual financial statements on a consolidated basis;

  2. details relating to certain acquisitions, disposals, takeovers, mergers and
     offers either made by or in respect of the company; and

  3. an explanatory circular or explanation in the annual report and accounts
     whenever a general meeting of the shareholders is convened that includes
     any business other than routine business at an annual general meeting
     (routine business includes such items as declarations of final dividends,
     approval of the report and financial statements, re-election of directors
     and appointment of auditors).

  In addition to the above requirements, a company is required to notify the LSE
of certain information, which the LSE will then publish.  These include details
of any notifications received by the company of interests of 3% or more in the
company's share capital, any changes in the Board of Directors, any purchase or
redemption by the company of its own shares, any changes in directors' interests
in the shares or the debentures of the company and changes in the share capital
of the company.  Unaudited half yearly reports of results for the first six
months of any financial year and an unaudited preliminary announcement of
results for any year must also be published.  Quarterly results are not required
to be published.

  There are additional obligations on companies listed on the LSE in relation to
transactions with related parties such as substantial shareholders, directors
(including directors within the last twelve months) of any group, company or
associates of such persons.  Where a transaction is proposed with a related
party, a circular to shareholders and the prior approval of the company at a
general meeting is generally required. The related party is not permitted to
vote at such general meeting.

                             SHAREHOLDER PROPOSALS

  In the event that the Merger is not consummated, proposals to be included in
LaTex's proxy statement relating to its next Annual Meeting of Shareholders must
have been delivered in writing to LaTex and received no later than December 9,
1996.

                   ENFORCEABILITY OF CIVIL LIABILITIES UNDER
                     UNITED STATES FEDERAL SECURITIES LAWS

  Alliance is a public limited company incorporated under the laws of England.
Six of its ten directors after completion of the Merger (and certain experts
named in this Proxy Statement) are not subject to the jurisdiction of the U.S.
because they are neither citizens nor residents of the U.S.  All or a
substantial portion of the assets of these persons and some of the assets of
Alliance and its subsidiaries are located in jurisdictions outside the U.S.  As
a result, it may not be possible for investors to effect service of process
within the U.S. upon these persons or upon Alliance or any of its subsidiaries
(other than its U.S. subsidiaries) or to realize upon judgments of U.S. courts
predicated upon civil liability under the U.S. federal or state securities laws.
Alliance has been advised by its English solicitors, Ashurst Morris Crisp, that
there is doubt as to the enforceability in the U.K. against Alliance or any of
its subsidiaries (other than its U.S. subsidiaries) or any of their respective
directors, controlling persons or executive officers or any of the experts named
in this Prospectus who are not residents of the U.S., in actions for enforcement
of judgments of U.S. courts of liabilities predicated upon, or in original
actions predicated solely upon, U.S. federal or state securities laws.
Nevertheless, Alliance has irrevocably agreed that, after the Merger is
completed, it may be served with process with respect to actions based on the
offer and sale of the New Alliance Shares made by this Proxy Statement by
serving Alliance at its principal U.S. operations office: Attention: President,
4200 East Skelly Drive, Suite 1000, Tulsa, Oklahoma 74135.

  Alliance has been advised by its English solicitors, Ashurst Morris Crisp,
that enforcement of judgments obtained outside the United Kingdom is subject to
detailed rules deriving in part from treaty, in part from statute and in part
from English common law. In particular, enforcement may not be permitted if a
judgment was obtained by fraud, was contrary to public policy of English law,
relates to foreign penal or revenue laws, is contrary to natural justice,
amounts to judgment on a matter previously determined by an English court, is
given in proceedings brought in breach of an agreement for settlement of
disputes or if enforcement of the judgment is restricted by the provisions of
the Protection of Trading Interests Act 1980 (which primarily relates to
multiple damages awards).

                             ADDITIONAL INFORMATION

  Alliance has filed with the Commission a Registration Statement on Form F-4
(together with any amendments thereto, the "Registration Statement") under the
Securities Act of 1933, as amended, of which this Prospectus is a part, with

                            REPORTS TO SHAREHOLDERS

  Upon completion of the Merger, Alliance will furnish its shareholders with
annual reports containing audited financial statements and the report thereon by
its auditors.  In addition, Alliance will furnish its shareholders such
additional unaudited financial statements and reports which are required by the
various governmental regulatory agencies to whom it must report. The financial
statements will be prepared under accounting principles generally accepted in
the United Kingdom and include a reconciliation of profit and loss for the year
and shareholders equity to amounts estimated to be in accordance with United
States generally accepted accounting principles, or will be prepared in
accordance with the United States generally accepted accounting principles.

                                              By Order of the Board of Directors

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors
ALLIANCE RESOURCES PLC

We have audited the consolidated financial statements of Alliance Resources Plc
and subsidiaries as listed in the accompanying index.  These consolidated
financial statements are the responsibility of the company's directors.  Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards
in the United Kingdom, which are substantially in accordance with generally
accepted auditing standards in the United States.  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 the directors 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 Alliance Resources Plc
and subsidiaries as of April 30, 1996 and 1995, and the results of their
operations and their cash flows for each of the years in the three year period
ended April 30, 1996 in conformity with generally accepted accounting principles
in the United Kingdom.

Generally accepted accounting principles in the United Kingdom vary in certain
significant respects from generally accepted accounting principles in the United
States.  Application of generally accepted accounting principles in the United
States would have affected the results of operations and shareholders' equity as
at and for the years ended April 30, 1995 and 1996, to the extent summarized in
Note 29 to the consolidated financial statements.

  STATEMENT OF DIRECTORS' RESPONSIBILITY FOR CONSOLIDATED FINANCIAL STATEMENTS

  UK company law requires the Directors to prepare financial statements for each
financial year which give a true and fair view of the state of affairs of the
Company and Group and of the profit or loss for that period.  In preparing those
financial statements, the Directors are required to:

  .   select suitable accounting policies and then apply them consistently;
   
  .   make judgments and estimates that are reasonable and prudent;
   
  .   state whether applicable accounting standards have been followed, subject
      to any material departures disclosed and explained in the financial
      statements;
   
  .   prepare the financial statements on the going concern basis unless it is
      inappropriate to presume that the Group will continue in business.

  The Directors are responsible for keeping proper accounting records which
disclose with reasonable accuracy at any time the financial position of the
Company and to enable them to ensure that the financial statements comply with
the UK Companies Act of 1985.  They have general responsibility for taking such
steps as are reasonably open to them to safeguard the assets of the Group and to
prevent and detect fraud and other irregularities.

                       NOTES TO THE FINANCIAL STATEMENTS

NOTE 1 - ACCOUNTING POLICIES

Basis of preparation

At the time of drawing up the 1995 financial statements, the Company was in the
process of investigating significant irregularities in the Group's affairs
during the period in which Mr. O'Brien was Chief Executive and a forensic
investigation had uncovered a number of matters which required significant
adjustments to the books and records of the Group.  In addition to the forensic
investigation, the Company instructed Ryder Scott Company, a firm of independent
petroleum reservoir engineers, to carry out an evaluation of the oil and gas
reserves attributable to the Group.  As the result of both the investigation
which had at that time not been concluded and the Ryder Scott Company reserve
review, exceptional write downs of $16,668,000 relating to the Group's oil and
gas reserves and $464,000 relating to fixed asset investments, were charged to
the profit and loss account.  It was not possible to properly allocate these
charges between items relating to the irregularities and the evaluation of the
Group's oil and gas reserves at that time.

The forensic investigation has been concluded and a settlement with Mr. O'Brien
has been agreed.  Consequently, $1,787,000 which had originally been capitalized
and provided for in the 1995 accounts as part of the $16,668,000 exceptional
write down of the Group's oil and gas fixed assets, has since been identified as
the estimated loss to the Group arising from the alleged fraudulent activities
and has now been reclassified as a separate item  (see note 4). The exceptional
write down relating to oil and gas assets has accordingly been restated as
$14,881,000.  The accumulated cost and depletion of oil and gas interests at 1
May 1995 have been reduced by $1,787,000.  In addition $285,000 of payments made
to acquire tangible fixed assets have been similarly classified to operating
cash flow.

The accounting policies set out below have been used by the Company in the
preparation of the financial statements.

Accounting convention

The financial statements have been prepared under the historical cost convention
and in accordance with applicable accounting standards in the United Kingdom.

Basis of consolidation

The consolidated financial statements comprise the financial statements of the
Company and its subsidiaries.

Goodwill

Goodwill relating to businesses purchased by the Group, where arising, is set
off immediately against reserves.

Reporting currency

The Group's current operations are in the oil and gas industry in the United
States and are conducted through its subsidiaries, Alliance Resources (USA),
Inc. and Source Petroleum, Inc. Transactions are conducted primarily in US
dollars.  As a result, the directors consider that the US dollar is the
functional currency of the Group and the Group's financial statements have been
prepared in US dollars.  The Company's share capital is denominated in sterling
and for the purposes of the financial statements, is translated into US dollars
at the rate of exchange at the time of its issue.

Foreign currency translation

The accounts of companies of the Group whose functional currency is not US
dollars are translated for consolidation purposes at the rate of exchange ruling
at the balance sheet date.  Exchange differences arising on the retranslation of
opening net assets are taken directly to reserves.

                ALLIANCE RESOURCES PLC AND SUBSIDIARY COMPANIES

                       NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)


For those companies whose functional currency is not US dollars, transactions
with third parties are translated into US dollars at the exchange rate
prevailing at the date of each transaction. Monetary assets and liabilities
denominated in foreign currencies are translated into US dollars at the exchange
rate prevailing at the balance sheet date. Any exchange gain or loss is dealt
with through the profit and loss account.

Abandonment

Provision is made for abandonment costs net of estimated salvage values, on a
unit-of-production basis, where appropriate.

Turnover

Turnover represents income from production and delivery of oil and gas, recorded
net of royalties and fees for the provision of technical services.  All turnover
arises from activities within the United States.

Oil and gas interests

The Group follows the full cost method of accounting for oil and gas operations
whereby all costs of exploring for and developing oil and gas reserves are
capitalized as tangible fixed assets.  Such costs include lease acquisition
costs, geological and geophysical costs, the  costs of drilling both productive
and non-productive wells, production equipment and related overhead costs.
Capitalized costs, plus estimated future development costs, are accumulated in
pools on a country-by-country basis and depleted using the unit-of-production
method based upon estimated proved net reserve volumes. Reserve volumes are
combined into equivalent units using relative energy content.

Costs of acquiring and evaluating unproved properties and major development
projects are excluded from the depletion calculation until it is determined
whether or not proved reserves are attributable to the properties, the major
development projects are completed, or impairment occurs, at which point such
costs are transferred into the pool.

Proceeds from the sale or disposal of properties are deducted from the relevant
cost pool with any overall deficit or surplus being recognized in the profit and
loss account.

The Group performs a 'ceiling test' calculation in line with industry practice.
Costs permitted to be accumulated in respect of each cost pool are limited to
the future estimated net recoverable amount from estimated production of proved
reserves.

Depreciation of other fixed assets

Other tangible fixed assets are stated at cost less accumulated depreciation.
Depreciation is provided on a straight line basis to reduce the cost of assets,
net of estimated residual values, over their estimated useful lives as follows:

Fixtures and equipment - 3 to 7 years
Freehold buildings - 30 years

No depreciation is provided on freehold land.

Deferred taxation

Deferred taxation, calculated using the liability method, is provided only where
it is probable that a liability will crystallize.

                       NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)


Joint ventures

The Group's exploration, development and production activities are generally
conducted in joint ventures with other companies.  The financial statements
reflect the relevant proportions of turnover, production, capital expenditure
and operating costs applicable to the Group's interests.

Fixed asset investments

Fixed asset investments are stated at cost less any provisions required for
permanent diminutions in value.

Leases

Rentals under operating leases are charged to the profit and loss account on a
straight line basis over the lease term.


Cash equivalents

Deposits with original terms of maturity of 90 days or less are considered to be
cash equivalents.

NOTE 2 - SEGMENTAL REPORTING

The Group's current operating activities are principally conducted in the United
States of America and relate to the oil and gas exploration and production
business and the provision of oil and gas services to this business.  All
turnover arises from activities within the United States of America, with
turnover by destination not materially different from turnover by origin.

NOTE 3 - EXCEPTIONAL AMOUNTS WRITTEN OFF OIL AND GAS INTERESTS

The proved oil and gas reserves of the Group and the net recoverable amount
arising therefrom were estimated as at April 30, 1995 by Ryder Scott Company, a
firm of independent petroleum engineers following the discovery that Valentine
#14 well was not capable of commercial production and that the Group had
relinquished title to its undeveloped acreage in the Valentine field.

The amount of $14,881,000 (see note 1) written off in the year to April 30, 1995
represents the write down relating to the carrying value of the Group's oil and
gas interests as restated after the reclassification of $1,787,000 as a separate
exceptional item (see note 4).  The net book value of the oil and gas interests
as at April 30, 1995 is included in the balance sheet at that date at the
estimated net amount recoverable through production.

NOTE 4 - EXCEPTIONAL COSTS ARISING FROM IRREGULARITIES

During the year ended April 30, 1996, following the discovery that Mr. O'Brien
appeared to have been fraudulently misrepresenting the position at the Valentine
field relating to the #14 well, the Company undertook (with the assistance of
external advisers) an investigation into the involvement of Mr. O'Brien in the
affairs of the Company.

This investigation has revealed that the Group has suffered a financial loss as
the result of a number of transactions involving Mr. O'Brien or parties now
known to have been connected with him.

Loss arising from transactions with certain companies related to Mr. O'Brien

The loss of $73,000 relates to an improper payment on the June 19, 1995 of
(Pounds)48,750 to Jasmine Consultants Limited. Jasmine Consultants Limited is an
off-shore company beneficially owned by Mr. O'Brien.

The loss of $1,787,000 arises from a number of transactions with certain
companies related to Mr. O'Brien in the year to April 30, 1995 as set out below:

  .  On August 10, 1994, the Company issued 7,500,000 ordinary shares to Progas
     Holdings Limited, a company in which Mr. O'Brien now admits to have an
     interest and which is incorporated in Delaware, USA.  This issue of shares
     was in consideration for a 5.75% working interest in the Valentine field.
     It has subsequently been discovered that Progas Holdings Limited acquired
     this interest in the Valentine field from its previous owners on 21 July
     1994 at a price of $255,000.

  .  On January 15, 1995 the Group entered into a loan agreement with Progas
     Holdings Limited to record the terms of a loan of which $1,129,000 had been
     advanced by Progas Holdings Limited between July 28, 1994 and December 16,
     1994.  The principal terms of the loan were:

     .    a facility of $1,400,000 to be drawn down solely for the purpose of
          drilling and developing the Valentine #14 well;

     .    if the well was successful in proving commercially recoverable
          quantities of oil and gas the amount drawn down together with a 100%
          premium would be payable to Progas Holdings Limited from commencement
          of production to July 30, 1995 at the latest, with the Group reserving
          a right of early settlement in full;

     .    if the well was abandoned within six months of the date of the
          agreement the amount drawn down was repayable immediately.

     .    On February 22, 1995, on the basis of representations from Mr. O'Brien
          that Valentine #14 well was successful, it was agreed that 10,351,966
          ordinary shares of the Company would be issued to Progas Holdings
          Limited at 6p per share in satisfaction of $1,000,000 of the debt with
          the remaining $1,258,000 to be repaid in cash.

     .    On May 10, 1995, 10,351,966 ordinary shares were so issued and the
          aggregate sum of (Pounds)794,000 was paid to Progas Holdings Limited
          to satisfy the liability of $1,258,000. The premium paid of $1,129,000
          was not justified.


     .    On April 5, 1995, the Group made a payment of $ 175,000 to Progas
          Holdings Limited for no apparent commercial reason.

                       NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)


     .    Between August 26, 1993 and September 1, 1993, the Group acquired a
          1.375% overriding royalty interest in the Valentine field from Royalty
          Investments Limited (a company which Mr. O'Brien now admits he owns),
          for $185,000. Royalty had acquired a 0.125% overriding royalty
          interest in the Valentine field from an unrelated third party on
          August 23, 1993 for $7,500. The Company believes the interest
          purchased to have been overvalued by $102,000.

Professional fees

The exceptional cost of $788,000 in the year to 30 April 1996 relates to the
estimated cost of professional assistance obtained by the directors in relation
to actions taken arising from the alleged fraudulent activities in the period in
which Mr. O'Brien was Chief Executive.

Estimated proceeds resulting from the settlement with Mr. O'Brien

The Company has reached a settlement with Mr. O'Brien.  One of the terms of the
settlement requires the disposal of 10,351,966 shares in the Company held in the
name of Progas Holdings Limited and the payment of the proceeds of sale of those
shares to the Company.  These shares are currently in the custody of an
independent third party, pending their sale.  Mr. J. A. Keenan, the Managing
Director of Alliance, has a proxy over the voting rights attaching to these
shares and to certain other shares in the Company held by Mr. O'Brien, Diamond
Securities Limited and Havensworth Limited, the latter two being companies
beneficially owned by Mr. O'Brien, pending their sale by Mr. O'Brien and these
companies as required by the settlement.  The exceptional credit of $272,000
relates to the expected proceeds resulting from the sale of the shares in the
name of Progas Holdings Limited calculated using the market price prior to
suspension of the Company's shares.

In the year ended April 30, 1995, in addition to the $68,000 charged to the
profit and loss account , $129,000 of fees paid to KPMG were charged to the

completed on May 9, 1995.

NOTE 7 - EXCEPTIONAL AMOUNTS WRITTEN OFF INVESTMENTS

Following the removal of Mr. O'Brien, the Group reviewed its portfolio of
investments, unlisted investments and joint venture interests.  It was
considered unlikely that significant amounts would be recovered from the
Tatarstan investment or from the Geos joint venture.  Accordingly, charges have
been made to the profit and loss account in the years ended April 30, 1995 and
1996 in respect of costs incurred in relation to these investments.

NOTE 9 - TAXATION

No material charge to UK corporation tax or US federal income tax arises on the
results for the year to April 30, 1996 (1995:$nil, 1994:$nil) due to the
availability of substantial losses for taxation purposes.

Deferred taxation has not been provided as at April 30, 1996 as sufficient
losses exist to extinguish potential deferred liabilities (1995: $nil; 1994:
$nil).

A substantial portion of the Group's oil and gas exploration, development and
production activities are conducted jointly with others.

All of the Group's producing oil and gas interests are located in one onshore US
oil and gas pool.

As at April 30,  1995 the Group had an interest in the Donkerbroek field, a non-
producing pre-development field located off-shore The Netherlands which had not
been included in the full cost pool and had not been subject to depletion.  On
June 5, 1995, the Group sold this interest for consideration after associated
costs of $398,000.  On July 12, 1995, the Group sold its oil and gas interests
in Colorado, USA for net consideration of $283,000.

Freehold land of $25,000 is not depreciated.

NOTE 19 - SPECIAL RESERVE

The special reserve of $4,300,000 at April 30, 1995 was set up as a result of a
reduction of share capital and share premium account approved by the High Court
on October 5, 1994 and was subject to restrictions imposed by the Court. These
restrictions were to become inoperative when new consideration of an equivalent
amount was received on shares issued after October 6, 1994.  This occurred on
May 9, 1995 and, accordingly, the reserve has been transferred to the
accumulated profit and loss account.

</TABLE> 

The consideration for the acquisition was satisfied by the issue of 3,205,128
ordinary shares and cash of $800,000. $113,000 was expended in costs connected
with the acquisition.

The amounts attributed to the assets and liabilities of Source represent
estimates of fair market values at the date of acquisition.  These amounts were
the same as the book values at acquisition, except that the net book value of
tangible fixed assets was $1,871,000 with the fair value uplift being $393,000
and the net book value of creditors was $1,611,000 with the fair value
attributed being $1,210,000.

The effect of the acquisition on the Group's results for the year to April 30,
1995 was to increase the loss for the financial year by $20,000.  Unaudited
financial statements of Source for the five month period ended April 30, 1995
showed a loss for the period of $20,000.

NOTE 25 - DIRECTORS' AND RELATED PARTY TRANSACTIONS

Transactions related with parties now known to be connected with Mr. O'Brien are
dealt with in note 4.

The following related party transactions occurred with North American Gas
Investment Trust PLC (NAGIT) which on May 9, 1995 became a substantial
shareholder of the Company:

(i)  July 29, 1994, the Group had entered into a loan agreement with NAGIT.

     The main terms of the interest free loan were:

     .    a facility of $250,000 to be drawn down solely for the purpose of
          drilling the Valentine #14 well;

     .    if the well was successful in improving commercially recoverable
          quantities of oil and gas, the capital drawn down together with a 100%
          premium would be payable to NAGIT from production at 30% of gross
          production revenues for the first 125 days, 50% of gross production
          thereafter to 365 days after which settlement of the remaining balance
          would be made in shares;

     .    if the well was abandoned, NAGIT was entitled to repayment in shares
          to the lesser of 5,000,000 ordinary shares of 1p each and the number
          of ordinary shares of 1p each to the value of $250,000;

     .    if drilling was suspended for more than 30 days due to lack of funds,
          NAGIT was entitled to repayment in shares to the value of $250,000.

     The full amount of the facility was drawn down.

     As Mr. O'Brien appeared to have fraudulently misrepresented that the
     Valentine #14 well was successful, on various dates between June 6, 1995
     and July 19, 1995 $347,307 in aggregate was originally paid to NAGIT
     representing payments from production volumes. Subsequent to the discovery
     of the fraudulent misrepresentation concerning the Valentine #14 well, this
     amount was off-set against the $1,300,000 cash element of the purchase and
     sale agreement with NAGIT (see(ii) below).

     At April 30, 1995 $250,000 was included as shares to be issued in respect
     of this agreement. These shares were issued on November 27, 1995 as
     discussed in note 17.

(ii) on January 25, 1995, NAGIT lent the Group $1,200,000 bearing interest at 7%
     per annum for assistance in the financing of the acquisition of  Source
     Petroleum Inc and to provide additional working capital. At April 30, 1995,
     $1,200,000 was outstanding and included in development loans  and this
     amount was repaid from the proceeds of the placing and open offer on May 9,
     1995;

(iii) on April 10, 1995, the Group entered into a purchase and sale agreement
      with NAGIT.

     The main terms of the agreement were:

     .    the Group would purchase a portfolio of producing properties located
          in the US with an effective date of January 1, 1995;

     .    consideration for the acquisition would comprise $1,300,000 in cash
          and the issue of 18,426,500 ordinary shares;

                                      F-26

                ALLIANCE RESOURCES PLC AND SUBSIDIARY COMPANIES
                 NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

     The 18,426,500 ordinary shares are included as shares to be issued at April
     30, 1995 at $1,780,000. The 18,426,500 ordinary shares were issued to NAGIT
     on May 9, 1995. At April 30, 1995 $1,300,000 was included in other
     creditors. This was settled by the payment on various dates of an aggregate
     amount of $347,307 and a payment on November 1, 1995 of $906,000.

NOTE 26 - SUBSEQUENT EVENTS

On August 13, 1996 the Company announced that it had entered into a conditional
agreement to effect a merger ("Merger") with LaTex Resources, Inc. ("LaTex"), a
company listed on the NASDAQ.  As a result of the Merger, the Company will issue
to the LaTex shareholders shares of the Company which will equal approximately
72% of the Company's issued shares after the Merger.  The Company's shareholders
will own approximately 28% of the issued shares after the Merger.  As a
condition of the Merger, the Company will effect a share consolidation, with the
result that each 40 shares that the Company's  shareholders currently own will
be converted into one share of the Company; the shares issued to the LaTex
shareholders will be adjusted to take this consolidation into account. At the
Company's request, The London Stock Exchange has suspended the listing of the
Company's shares pending further details of the reorganization of the Company.

Alliance's directors have reached agreement in principle with LaTex's lenders
that LaTex's current facility will be amended with the principal effect that
capital repayments will be suspended until 18 months following completion of the
Merger. The directors consider that the amended facility will provide a sound
financial base for the enlarged group. The Merger is conditional upon a suitable
facility being finalized.

On August 13, 1996, the Company also announced that it has agreed terms to stay
its current litigation against Mr. John O'Brien, its former Chief Executive and
other companies beneficially owned by Mr. O'Brien. Mr. O'Brien has also
withdrawn a counterclaim made against the Company (see note 4).

Other transactions occurred subsequent to April 30, 1996 as follows:

(i)   On May 13, 1996 the Group announced that one of its US subsidiaries ARNO
      Inc had reached agreement on the sale of its interest in four leases
      comprising the McPac field, Matagorda Island, offshore Texas to Louisiana
      Land and Exploration Company for a cash consideration of $525,000. The
      Group's interest in these blocks varied between 4.2% and 6.3% and its
      interest in the McPac platform was 6.3%. On May 30, 1996, the Group
      completed this transaction and the gross consideration was adjusted to
      reflect the impact of the effective date of January 1, 1996 and a gas
      overlift imbalance. This resulted in a net cash consideration of $432,000,
      which has been taken as a credit against the carrying cost of the Group's
      oil and gas assets in the year to April 30, 1997.

(ii)  On August 15, 1996 the Group disposed of its interest in 4 leases
      comprising the Provident City field, Lavaca County, onshore Texas to Shana
      Petroleum for a net cash consideration of $435,000. The Groups' working
      interest in these blocks varied between 17.7% and 42.4%. The proceeds of
      the sale have been taken as a credit against the carrying cost of the
      Group's oil and gas assets in the year to April 30, 1997.

(iii) In August 1996 the Company transferred its interest in Geological Forecast
      Technology Ltd by transferring its 50 'A' shares to Geos Seismology
      Limited as part of a final settlement of an action brought by the latter.

(iv)  On October 3, 1996, the Group announced that one of its US subsidiaries
      ARNO Inc had reached agreement for the sale of its interests in three US
      oil and gas fields to BWAB Incorporated for a cash consideration of
      $1,425,000. The disposal covered the Group's interests in the Frost,
      Gilmer South and Mocane Laverne fields, which are located in Texas and
      Oklahoma and had combined remaining reserves of 25,920 barrels of oil and
      1,720 million cubic feet of gas as at May 1, 1996, representing
      approximately 16% of the Group's total proved and probable reserves. The
      interests comprised 26 wells and the working interests in those wells
      varied between 5% and 28%. The proceeds of the sale have been taken as a
      credit against the carrying cost of the Group's oil and gas assets in the
      year to April 30, 1997.

NOTE 27 - LITIGATION AND CONTINGENCIES

The Group is party to the following litigation:

(i)   the Group is seeking to recover $1,300,000 of unpaid drilling costs from
      Drexco Inc, with Drexco Inc and H Huizenga claiming unspecified damages in
      respect of conduct, and removal of Alliance Resources (USA) Inc as
      operator of the Valentine field. The Group has obtained legal advice and
      will vigorously prosecute its claim against Drexco Inc. The Group denies
      the counter claim and will vigorously defend the matter;

(ii)  the Group has received, on September 12, 1996, a writ from Best Royalties
      Plc claiming $186,368 and a declaration that they are entitled to a sum
      equal to 40% of Alliance (USA) Inc's net cash proceeds received from the
      Arrowhead well (and payment of the said sum), alternatively damages, plus
      interest thereon. The Group denies the claim and will vigorously defend
      this matter;

(iii) Ernest M Closuit et al. have asserted a claim against the Group for
      alleged underpayment of amounts due for Closuit et al.'s interest in the
      Buller No. 2 well in the South Elton field and have further claimed an
      interest in past and future production from certain other wells in the
      field. Total claims amount to approximately $1,200,000. Discovery has just
      begun. The Group denies all allegations and claims and will vigorously
      defend this matter;

(iv)  the directors have not been notified and do not expect to be notified of
      any claims arising from the alleged fraudulent activities of Mr. O'Brien.

NOTE 29 - SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES GENERALLY
ACCEPTED IN THE UNITED KINGDOM AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING
PRINCIPLES

The Company's accounting policies conform with United Kingdom generally accepted
accounting principles ("UK GAAP") which differ in certain respects from United
States generally accepted accounting principles ("US GAAP"). Differences which
have a significant effect on the consolidated profit after tax (net income) and
shareholders' equity of the Group are set out below.

(a)  Ceiling tests

A ceiling test has been carried out, in accordance with UK GAAP on an annual
basis, to determine the maximum net book amount of expenditure within the cost
pool of oil and gas assets which may be recognized.  The ceiling test is based
on the Company's best estimate of the future cash flows from the underlying
properties.  Under US GAAP, SEC regulations require ceiling tests to be computed
at current prices discounted to present value at 10%.

Under UK GAAP a ceiling test deficit should be written off to expense only if it
indicated a permanent diminution in value.  Under US GAAP any deficit should be
charged immediately to the profit and loss account.

                 NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

(b)  Goodwill

Under UK GAAP goodwill arising on acquisitions has been set off directly against
reserves.  Under US GAAP, goodwill arising from acquisitions is capitalized and
amortized over its estimated useful life.  However, following irregularities
mentioned above, US GAAP requires the balance to be written of in 1995.

(c) Estimated proceeds of Alliance shares

As set out in note 4, the Company has recognized an exceptional credit of
$272,000 relating to the right to receive the proceeds of the sale of Alliance
shares resulting from the settlement with Mr. O'Brien under UK GAAP. Under US
GAAP, such proceeds are recognized only on receipt.

(d)  Statements of cash flows

The Company has adopted United Kingdom Financial Reporting Standard No. 1 "Cash
Flow Statements" ("FRS 1"). Its objectives and principles are similar to those
set out in the US Statement of Financial Standards No. 95 "Statement of Cash
Flows" ("SFAS 95"). The principal difference between the standards relates to
classification. Under FRS 1, the Company presents its cash flows from (a)
operating activities; (b) returns on investments and servicing of finance; (c)
taxation; (d) investing activities; and (e) financing activities. SFAS 95
requires only three categories of cash flow activity: (a) operating; (b)
investing; and (c) financing. Cash flows and taxation and returns on investments
and servicing of finance shown under FRS 1 would, with the exception of
dividends paid, be included as operating activities under SFAS 95. The payment
of dividends would be included as a financing activity under SFAS 95.

For purposes of reporting cash flows, all cash at bank and in hand and bank
overdrafts repayable on demand are considered cash equivalents.

                 SUPPLEMENTAL OIL AND GAS DATA - (UNAUDITED)

The following supplemental information on oil and gas exploration and production
activities of the group is presented in accordance with Statement of Financial
Accounting Standards No. 69 "Disclosures about Oil and Gas Producing Activities"
("FAS 69").

ESTIMATED QUANTITIES OF PROVED OIL AND GAS RESERVES

The Group's estimated proved developed and undeveloped reserves of oil and gas
and changes thereto for the years 1994, 1995 and 1996 and proved developed
reserves of oil and gas at each year end are set forth in the following  table.

Ryder Scott Company, an independent firm of petroleum engineers, carried out an
evaluation of approximately 71% of the Group's proved reserves for the year
ended April 30, 1996 and 100% of the Group's reserves as of April 30, 1995. The
reserves estimated as of April 30, 1994 are based on an evaluation carried out
by Metrovest, an independent firm of petroleum engineers, as of January 1, 1994,
flexed for production to April 30, 1994.

Proved reserves are reserves of crude oil, condensate, natural gas and natural
gas liquids and are estimated quantities as of a specific date, which geological
and engineering data demonstrate with reasonable certainty to be recoverable in
the future from known reservoirs under existing economic and operating
conditions.

Due to the inherent uncertainties and the limited nature of reservoir data,
estimates of reserve quantities are subject to change over time as additional
information becomes available.

Oil reserves, which include condensate and natural gas liquids, are stated in
thousands of barrels and gas reserves are stated in millions of cubic feet.

Subsequent to April 30, 1996, Alliance has sold substantial properties.  See
"Alliance-Recent Developments".  The reserves attributable to those properties
accounted for approximately 25% of Alliance's proved reserves at April 30, 1996.

STANDARD MEASURE OF DISCONTINUED FUTURE NET CASH FLOWS RELATING TO PROVED CRUDE
OIL & GAS RESERVES QUANTITIES

The standardized measure of discounted future net cash flows related to proved
crude oil and natural gas reserves is calculated in accordance with the
requirements of SFAS 69 and uses reserve definitions as prescribed by the
Financial Accounting Standards Board. Estimated future cash flows from
production are computed by applying year end prices for crude oil and natural
gas and year-end exchange rates to year end quantities of estimated net proved
reserves. Future price changes are limited to those provided by contractual
arrangements in existence at the end of the reporting year. Future development
and production costs are those estimated future expenditures necessary to
develop and produce year end estimated proved reserves based on year-end price
levels and assuming the continuance of year end economic conditions. Future
production costs include estimated abandonment liabilities. Discounted future
net cash flows are calculated using 10% mid-period discount factors.

The information provided below does not represent management's estimate of the
Company's expected future cash flows or value of proved reserves.  Estimates of
proved reserve quantities are imprecise and change over time as new information
becomes available and in particular, probable and possible reserves, which may
become proved reserves in 1997 or later, are excluded from the calculations.
Also, assumptions have been required regarding the timing of future production
and the timing and amount of future development and production costs.  The
calculations assume that economic conditions existing at the end of the
reporting year will continue.  Other different but equally valid assumptions
might lead to significantly different final results.  Although calculated in
accordance with SFAS 69, the Company therefore cautions against the placing of
unwarranted reliance on this information in view of the highly arbitrary nature
of the assumptions on which it is based.

NOTES

1.   The comparative figures for the financial year ended April 30, 1996 are not
     the Group's statutory accounts for that year. Those accounts have been
     reported on by the Group's auditors and delivered to the Registrar of
     Companies. The report of the auditors was unqualified but included a
     statement regarding the adequacy of the Group's accounting records pending
     completion of the investigations into the activities of Mr. O'Brien, the
     former Chief Executive.

2.   The interim financial information for the six months ended October 31, 1996
     is unaudited and has been prepared in accordance with the accounting
     policies adopted in the statutory financial statements for the year ended
     April 30, 1996. The interim results reflect all adjustments which are, in
     the opinion of the directors, necessary for a fair presentation of the
     results for the interim periods presented and should be read in conjunction
     with the Consolidated Financial Statements presented elsewhere in this
     Proxy Statement. The interim results have been prepared in accordance with
     UK GAAP which differ in certain significant respects from US GAAP (see
     below).

     UNAUDITED INTERIM STATEMENT FOR THE SIX MONTHS ENDED OCTOBER 31, 1996

3.   The comparative figures for the six months ended October 31, 1995 have been
     extracted from the unaudited interim financial information dated on
     February 28, 1996.

4.   During the six months to October 31, 1996, the Group completed its review
     of non-core assets and disposed of the non-operated properties owned by the
     wholly-owned subsidiary ARNO Inc. After depletion, the gross profit
     attributable to the properties disposed of in the period to October 31,
     1996 was insignificant.

5.   The exceptional costs arising from irregularities of $120,000 charged in
     the six month period ended October 31, 1996 relate largely to legal fees
     incurred in connection with the earlier proceedings against Mr. O'Brien and
     the subsequent settlement announced on August 13, 1996.

6.   Included in debtors of $1,911,000 is an amount of $650,000 relating to
     professional fees incurred to date on the LaTex merger. It should be noted
     that this is an interim accounting treatment only and that on completion of
     the proposed transaction, the expenses relating to the merger itself will
     be capitalized as part of the cost of acquisition and the expenses relating
     to the issue of shares will be offset against the share premium account in
     accordance with the requirements of companies legislation.

7.   Loss per share is based on the loss for the six months ended October 31,
     1996 and on the weighted average of 324,152,633 ordinary shares of 1p each
     in issue during the period.

8.   The directors do not propose to recommend the payment of an interim
     dividend.

SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN THE
UNITED KINGDOM AND THE UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES.

The Company's accounting policies conform with United Kingdom generally accepted
accounting principles ("UK GAAP") which differ in certain respects from United
States generally accepted accounting principles ("US GAAP"). Differences which
have a significant effect on the consolidated profit after tax (net income) and
shareholders' equity of the Group are set out below.

(a)  Ceiling tests

A ceiling test has been carried out, in accordance with UK GAAP on an annual
basis, to determine the maximum net book amount of expenditure within the cost
pool of oil and gas assets which may be recognized.  The ceiling test is based
on the Company's best estimate of the future cash flows from the underlying
properties.  Under US GAAP, SEC regulations require ceiling tests to be computed
at current prices discounted to present value at 10%.

Under UK GAAP a ceiling test deficit should be written off to expense only if it
indicated a permanent diminution in value.  Under US GAAP any deficit should be
charged immediately to the profit and loss account.

(b)  Goodwill

Under UK GAAP goodwill arising on acquisitions has been set off directly against
reserves.  Under US GAAP, goodwill arising from acquisitions is capitalized and
amortized over its estimated useful life.  However, following irregularities
mentioned above, US GAAP requires the balance to be written off in 1995.

(c) Estimated proceeds of Alliance shares

As set out in note 4, the Company has recognized an exceptional credit of
$272,000 relating to the right to receive the proceeds of the sale of Alliance
shares resulting from the settlement with Mr. O'Brien under UK GAAP.  Under US
GAAP, such proceeds are recognized only on receipt.

     UNAUDITED INTERIM STATEMENT FOR THE SIX MONTHS ENDED OCTOBER 31, 1996

(d)  Statements of cash flows

The Company has adopted United Kingdom Financial Reporting Standard No. 1 "Cash
Flow Statements" ("FRS 1"). Its objectives and principles are similar to those
set out in the US Statement of Financial Standards No. 95 "Statement of Cash
Flows" ("SFAS 95"). The principal difference between the standards relates to
classification. Under FRS 1, the Company presents its cash flows from (a)
operating activities; (b) returns on investments and servicing of finance; (c)
taxation; (d) investing activities; and (e) financing activities. SFAS 95
requires only three categories of cash flow activity: (a) operating; (b)
investing; and (c) financing. Cash flows and taxation and returns on investments
and servicing of finance shown under FRS 1 would, with the exception of
dividends paid, be included as operating activities under SFAS 95. The payment
of dividends would be included as a financing activity under SFAS 95.

For purposes of reporting cash flows, all cash at bank and in hand and bank
overdrafts repayable on demand are considered cash equivalents.

applied, except that the April 30, 1996 unaudited interim financial statements
do not contain footnotes (that, if presented, would not differ materially from
those in the audited LaTex Financial Statements) and are subject to normal,
recurring year-end adjustments (which will not, individually or in the
aggregate, have a Material Effect).

          (b)  The LaTex Financial Statements were prepared from the books and

being developed, operated and maintained in material compliance with the LaTex
Oil and Gas Contracts.  In operating the LaTex Interests, the LaTex Entities are
not dependent on the right to use the property of others, except under valid and
enforceable agreements, rights or other arrangements included in the LaTex Oil
and Gas Contracts.

          (b)   Since April 30, 1996, none of the LaTex Entities, directly or

other than sales of property in any single transaction having a value of less
than $25,000, and, to the knowledge of the LaTex Entities, the LaTex Interests
have not suffered any destruction, damage, or loss (except depreciation of

similar rights, the exercise of which would reduce the LaTex's Entities' Net
Revenue Interests to less than the Net Revenue Interests set forth in Exhibits
                                                                      --------

Agreements") and no material transportation agreements relating to the LaTex

exists no material imbalance regarding production taken or marketed from any
Lease included in the LaTex Interests or otherwise affecting any of the LaTex
Entities which could result in (i) a portion of its interest in production
therefrom to be taken or delivered after the Closing Date without the applicable
entity receiving full payment therefor and at the price it would have received
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)
production being shut-in or curtailed after the Closing Date due to non-
compliance with allowables, production quotas, proration rules or similar orders
or regulations of a Governmental Entity; and none of the LaTex Entities is
obligated, by virtue of any prepayment arrangement take-or-pay agreement or
similar arrangements to deliver Hydrocarbons produced from the LaTex Interests
at some future time without then receiving full payment therefor in all material
respects.

natural gas liquids and gas reserves attributable to the LaTex Interests as of
the date of the LaTex Reserve Report are materially less than the estimates of
quantities of those reserves shown in the LaTex Reserve Report; (e) none of the
LaTex Entities have any knowledge of any change (other than normal depletion by
production in the ordinary course, price changes, and sales of property in any
single transaction having a value of less than $25,000) occurring since the date
of the LaTex Reserve Report that would result in a material change in the
information contained in the LaTex Reserve Report, and (f)  to the knowledge of
the LaTex Entities, none of the LaTex Entities or the LaTex Interests are

considered in context and together with all relevant information made available.

          4.25  Litigation.
                ---------- 

          (a)   There is no action, proceeding, investigation or inquiry pending
or, to the knowledge of the LaTex Entities, threatened (i) against or affecting
any of the LaTex Entities or their assets or ordinary conduct of the business
that, if determined adversely to the LaTex Entities, would result in a Material
Effect or (ii) that questions this Agreement or any action contemplated by this
Agreement or in connection with the Merger.

          (b)   There are no citations, fines or penalties heretofore asserted
against any of the LaTex Entities or their assets under any federal, state or
local law relating to air, noise or water pollution or other environmental
protection matters, or relating to occupational health or safety, of which such
entity has received notice and that remain unpaid or that could otherwise bind
the assets of any of the LaTex Entities and that would result in a Material
Effect.

          (c)   LaTex has no knowledge of any state of facts or of the
occurrence or nonoccurrence of any event or group of related events, that should
reasonably cause LaTex to determine that there exists any basis for any material
claim against the LaTex Entities for any of the matters described in paragraphs
(a) or (b).

          4.26  Tax Returns and Payments.
                ------------------------ 

          (a)   The LaTex Entities (or the common parent of any affiliated group
of which any of such entities is or has been a member) have duly filed in
correct form in all material respects all Tax Returns required to be filed by
such entities and have duly paid or provided for payment of (or there have been
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
contested in good faith by appropriate proceedings and as to which adequate
reserves have been provided and that are specially identified in Section 4.26 of
                                                                 ---------------

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

          (b)   There are no tax liens upon any property or assets owned by any
of the LaTex Entities that would have a Material Effect.

          (c)   All Tax Returns of the LaTex Entities filed, including any
amendments to date, have been prepared in good faith without willful
misrepresentation and are complete and accurate in all material respects.  The
federal income tax returns of the LaTex Entities have been examined by the
Internal Revenue Service for all periods through December 31, 1990, and all
deficiencies assessed as a result of such examination have been paid in full or
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
Entities or is still pending and, by application of similar  principles,
reasonably could be expected to result in an assertion by the Internal Revenue
Service of a material deficiency in any other taxable year or with respect to
any other of the LaTex Entities. There are no outstanding agreements, waivers or
other arrangements providing for an extension of time with respect to the filing
of any Tax Returns or the payment by, or assessment against, any of the LaTex
Entities for any Taxes.  Each of the LaTex Entities is taxed as a C corporation
under the Code.

          (d)   The reserves made for Taxes on the respective balance sheets in
the LaTex Financial Statements are sufficient for the payment of all unpaid
Taxes due and payable by the LaTex Entities attributable to all periods ended on
or before the date of the respective balance sheets in accordance with GAAP.

compensation and other forms of insurance owned or held by or for the benefit of

LaTex Interests where one of the LaTex Entities is not the operator).  All such
policies are sufficient for material compliance with all requirements of law and
all agreements for which those entities are parties, are, to the knowledge of
the LaTex Entities, valid and enforceable policies, will remain in full force
and effect through the respective dates set forth in Section 4.27 of the LaTex

                        OPINIONS OF WOOD ROBERTS, LLC.



August 8, 1996


The Board of Directors
LaTex Resources, Inc.
4200 East Skelly Drive, Suite 1000
Tulsa, Oklahoma  74135

Gentlemen:

You have asked Wood Roberts, LLC. to examine the terms of the proposed merger
(the "Merger") between LaTex Resources, Inc. ("LaTex") and Alliance Resources
PLC ("Alliance"), as set forth in the Agreement and Plan of Merger scheduled to
be executed on August 9, 1996 (the "Agreement"), in conjunction with the
proposed disposal of certain assets of LaTex as provided by the Agreement, and
to render an opinion as to the fairness of such terms from a financial stand
point to the shareholders of LaTex.

Pursuant to the Agreement, Alliance Resources (Delaware), Inc. ("Alliance
Delaware"), a newly formed, wholly owned subsidiary of Alliance, will be merged
with and into LaTex and the separate corporate existence of Alliance Delaware
will cease.  LaTex will be the surviving corporation in the Merger and will be a
wholly owned subsidiary of Alliance.

All issued and outstanding Common Shares, Series A Shares and Series B Shares of
LaTex will be canceled and, in consideration of such cancellation, the holders
will become entitled to the allotment of common shares of Alliance with a par
value (Pounds)0.40 ("Alliance Shares") in the total amount of 21,448,787
Alliance Shares, equal to 72% of the then issued Alliance Shares, and in amounts
for each Common Share, Series A Share and Series B Share as will be set forth in
the Agreement prior to execution.  In consequence, the opinion expressed
hereinbelow is qualified with respect to the fairness of the allocation of
Alliance Shares between the separate classes of LaTex Shares.

Each warrant to purchase LaTex Common Shares (a "Warrant") will be canceled and,
in consideration of such cancellation, the holder will become entitled to
receive a new warrant to subscribe for the number of Alliance Shares that the
holder of the Warrant would have been entitled to receive if such holder had
exercised the Warrant prior to the Merger and received LaTex shares.  The
holders of Warrants will have the right to subscribe to a further number of
Alliance Shares as will be set forth in the Agreement.

The Alliance Shares are currently traded on the London Stock Exchange and LaTex
Common Shares are traded on the over the counter market of the NASD.  Following
the Merger, the Alliance Shares will be traded on the London Stock Exchange and
no market will be made on NASDAQ.

It is a condition of the Agreement that the Merger will qualify as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986 and that the exchange of shares in the Merger will not give rise to gain
or loss to LaTex or its shareholders. As of the date of this letter, Alliance is
in negotiation with certain other entities regarding the potential acquisition
of other assets or companies.  We cannot give an opinion on the effect of such
potential acquisitions on the shareholders of LaTex.  However, the terms of the
Agreement provide that the terms of such potential acquisitions must be
acceptable to LaTex prior to the execution of an agreement relating thereto.

The Agreement excludes certain non-performing assets of LaTex from the Merger.
Such assets will be sold to Imperial Petroleum, Inc. for a consideration of
100,000 LaTex Common Shares.

                                     C-1-1

In arriving at our opinion, we have reviewed the Agreement, information provided
to us by the management of LaTex and Alliance and by certain of their
professional advisors, as well as information that is in the public domain.
Furthermore, we have had the opportunity of meeting with the management of LaTex
and Alliance to discuss the historical and current business of each company,
their prospects as stand-alone entities and the potential short-term and medium-
term strategic and financial benefits of the proposed Merger.

Our review of the terms of the Merger has been undertaken with reference to,
among other things:  the relative net asset values of LaTex and Alliance;
financial condition and debt ratios; earnings, cash flow and the ability to
develop or re-work assets; and the pro forma financial position of the merged
company and its ability to obtain debt or equity funding. We have analyzed
certain financial, industry and market related information and data.
Furthermore, we have examined data indicative of the relative merits of LaTex
shareholders exchanging their shares for shares listed for trading on the London
Stock Exchange. We have not been asked to undertake an independent analysis of
comparable transactions. However, we have reviewed certain published data in
this regard.

We have not independently verified any of the foregoing information and, in
using such information in our review of the Merger, we have relied upon it being
complete and accurate in all material respects.

In any merger of publicly traded companies, regulatory and governmental
approvals must be sought and obtained.  In our review of the Merger of LaTex and
Alliance, we have assumed that such approvals will be forthcoming and that no
restriction will be imposed that will have a material adverse effect on the
contemplated benefits of the Merger.  Our opinion is rendered on the basis of
our knowledge of the circumstances disclosed to us as of the date of this
letter.

We act as financial advisor to LaTex in relation to the Merger.  We have
received fees for such services in the past and have an agreement with LaTex for
the payment of a fee if the Merger is consummated. John R. Martinson, a director
of LaTex, is a principal of Wood Roberts, LLC.  Mr. Martinson has recused
himself from consideration of the terms of the Merger for the purpose of this
opinion.

Based upon the results of our analysis of the matters set forth above, our
knowledge of the market for and valuation of securities in the U.S.A. and the
United Kingdom, our overall experience in the energy sector in both of the
aforementioned countries, all other factors that we consider to be relevant and
subject to the qualification hereinbefore stated, we are of the opinion that the
financial terms of the Merger are fair to the shareholders of LaTex.

Yours sincerely,



WOOD ROBERTS, LLC.

The Board of Directors
LaTex Resources, Inc.
4200 East Skelly Drive, Suite 1000
Tulsa, Oklahoma  74135

Gentlemen:

You have asked Wood Roberts, LLC. to examine the proposed amended Section 9(k)
of the proposed merger (the "Merger") between LaTex Resources, Inc. ("LaTex"),
and Alliance Resources Plc ("Alliance") and Alliance Resources (Delaware), Inc.
("Alliance Delaware"), as set forth in the Agreement and Plan of Merger dated
August 12, 1996 (the "Agreement") and to render an opinion as to the fairness of
such amendment from a financial standpoint to the shareholders of LaTex.

The amendment, as proposed by Alliance, seeks to eliminate the condition that
counsel for Alliance and Alliance Delaware shall issue a satisfactory opinion
that the Merger is a tax free reorganization under Section 368(a) of the
Internal Revenue Code of 1986 and that the exchange of LaTex shares and warrants
for Alliance shares will not give rise to gain or loss to the LaTex
shareholders.

In rendering this further opinion, Wood Roberts has relied upon information
provided to it by LaTex to the effect that the transaction will be a taxable
event and offers no opinion as to the tax status of the transaction.
Furthermore, Wood Roberts has not been asked to, nor is it willing to, provide
an opinion on the tax effect of the transaction on individual shareholders or
classes of shareholders, and all such shareholders should consult their own tax
advisor with reference to their own position.

The contents of this opinion and the related analysis provided herewith should
be considered in conjunction with and subject in all respects to the terms of
reference, contents of and limitations to the fairness opinion rendered by Wood
Roberts in relation to the Merger on August 8, 1996.

Based upon our understanding of the tax effect of the proposed amendment, our
knowledge of the historical and current price of LaTex shares, our knowledge of
the market for and valuation of securities in the U.S.A. and the United Kingdom,
our experience in the energy sector in both of the aforementioned countries, the
overall and continuing benefits to be obtained by the shareholders of LaTex from
the Merger with Alliance, all other factors that we consider to be relevant, and
subject to the qualifications hereinbefore stated, we are of the opinion that
the financial terms of the Merger remain fair to the shareholders of LaTex.

Yours sincerely,



WOOD ROBERTS, LLC.

March 11, 1997


The Board of Directors
LaTex Resources, Inc.
4200 East Skelly Drive, Suite 1000
Tulsa, Oklahoma 74135

Gentlemen:

The terms of the proposed merger (the "Merger") between LaTex Resources, Inc.
("LaTex"), Alliance Resources Plc ("Alliance") and Alliance Resources
(Delaware), Inc. ("Alliance Delaware"), as set forth in the Agreement and Plan
of Merger dated August 12, 1996 (the "Agreement") have been amended with respect
to the allocation of New Alliance Shares between the various classes of LaTex
shareholders.

The fairness of the Merger to the shareholders of LaTex as a group from a
financial standpoint has been examined and opinions of Wood Roberts on this
matter have been provided to the Board of Directors of LaTex in opinions dated
August 6, 1996 and October 1, 1996. You have asked Wood Roberts to provide an
opinion as to the fairness of the amended allocation of the shares of New
Alliance between the three classes of LaTex stock:  the Common, the Series A
Convertible Preferred and Series B Senior Convertible Preferred.

The contents of this opinion and all related analyses must be considered in
conjunction with and subject in all respects to the terms of reference, contents
of and limitations to the previous fairness opinions rendered by Wood Roberts in
relation the Merger. As previously, Mr. John Martinson has recused himself from
the consideration of the matters addressed herein.

The aggregate number of New Alliance Shares to be issued to the shareholders of
LaTex will remain unchanged in the total amount of up to 21,448,787 shares,
equal to approximately 72% of the then issued New Alliance Shares. However,
pursuant to the amended terms, the LaTex shareholders will receive: 0.85981 New
Alliance Shares for each Common Share; 2.58201 New Alliance Shares for each
Series A Convertible Preferred Share; and 6.17632 New Alliance Shares for each
Series B Senior Convertible Preferred Share.

The amendment to the terms has been made for two reasons: first, because the
payment of quarterly preference dividends attributable to the Series A
Convertible Preferred Stock and Series B Senior Convertible Preferred Stock has
been satisfied, in the same manner as all previous dividends, by the issuance of
additional shares of preferred stock, thereby increasing the proportion of the
Company owned by such preferred shareholders; and, second, so as properly to
reflect the value of the senior preference rights of the Series B Senior
Convertible Preferred Stock.

Based upon our analysis of the rights attaching to each class of LaTex share and
the number of such shares issued, Wood Roberts is of the opinion that the
allocation of the New Alliance Shares between the three classes of LaTex shares
is fair to the holders of each class.


Yours sincerely,


WOOD ROBERTS LLC

                       DELAWARE GENERAL CORPORATION LAW

(S)262.  APPRAISAL RIGHTS.

  (a)  Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to (S)228 of this
title shall be entitled to an appraisal by the Court of Chancery of the fair
value of his shares of stock under the circumstances described in subsections
(b) and (c) of this section.  As used in this section, the word "stockholder"
means a holder of record of stock in a stock corporation and also a member of
record of a nonstock corporation; the words "stock" and "share" mean and include
what is ordinarily meant by those words and also membership or membership
interest of a member of a nonstock corporation; and the words "depository
receipt" mean a receipt or other instrument issued by a depository representing
an interest in one or more shares, or fractions thereof, solely of stock of a
corporation, which stock is deposited with the depository.

  (b)  Appraisal rights shall be available for the shares of any class or series
of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to (S)251, (S)252, (S)254, (S)257, (S)258, (S)263 or (S)264 of
this title:

     (1)  Provided, however, that no appraisal rights under this section shall
  be available for the shares of any class or series of stock, which stock, or
  depository receipts in respect thereof, at the record date fixed to determine
  the stockholders entitled to receive notice of and to vote at the meeting of
  stockholders to act upon the agreement of merger or consolidation, were either
  (i) listed on a national securities exchange or designated as a national
  market system security on an interdealer quotation system by the National
  Association of Securities Dealers, Inc. or (ii) held of record by more than
  2,000 holders; and further provided that no appraisal rights shall be
  available for any shares of stock of the constituent corporation surviving a
  merger if the merger did not require for its approval the vote of the
  stockholders of the surviving corporation as provided in subsections (f) or
  (g) of (S)251 of this title.

     (2)  Notwithstanding paragraph (1) of this subsection, appraisal rights
  under this section shall be available for the shares of any class or series of
  stock of a constituent corporation if the holders thereof are required by the
  terms of an agreement of merger or consolidation pursuant to (S)(S)251, 252,
  254, 257, 258, 263 and 264 of this title to accept for such stock anything
  except:

          a.   Shares of stock of the corporation surviving or resulting from
     such merger or consolidation, or depository receipts in respect thereof;

          b.   Shares of stock of any other corporation, or depository receipts
     in respect thereof, which shares of stock or depository receipts at the
     effective date of the merger or consolidation will be either listed on a
     national securities exchange or designated as a national market system
     security on an interdealer quotation system by the National Association of
     Securities Dealers, Inc. or held of record by more than 2,000 holders;

          c.   Cash in lieu of fractional shares or fractional depository
     receipts described in the foregoing subparagraphs a. and b. of this
     paragraph; or

          d.   Any combination of the shares of stock, depository receipts and
     cash in lieu of fractional shares or fractional depository receipts
     described in the foregoing subparagraphs a., b. and c. of this paragraph.

     (3)  In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under (S)253 of this title is not owned by the
  parent corporation immediately prior to the merger, appraisal rights shall be
  available for the shares of the subsidiary Delaware corporation.

  (c)  Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all 

                                      D-1
<PAGE>
 
of the assets of the corporation. If the certificate of incorporation contains
such a provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.

  (d)  Appraisal rights shall be perfected as follows:

       (1)  If a proposed merger or consolidation for which appraisal rights are
  provided under this section is to be submitted for approval at a meeting of
  stockholders, the corporation, not less than 20 days prior to the meeting,
  shall notify each of its stockholders who was such on the record date for such
  meeting with respect to shares for which appraisal rights are available
  pursuant to subsection (b) or (c) hereof that appraisal rights are available
  for any or all of the shares of the constituent corporation, and shall include
  in such notice a copy of this section.  Each stockholder electing to demand
  the appraisal of his shares shall deliver to the corporation, before the
  taking of the vote on the merger or consolidation, a written demand for
  appraisal of his shares. Such demand will be sufficient if it reasonably
  informs the corporation of the identity of the stockholder and that the
  stockholder intends thereby to demand the appraisal of his shares.  A proxy or
  vote against the merger or consolidation shall not constitute such a demand.
  A stockholder electing to take such action must do so by a separate written
  demand as herein provided.  Within 10 days after the effective date of such
  merger or consolidation, the surviving or resulting corporation shall notify
  each stockholder of each constituent corporation who has complied with this
  subsection and has not voted in favor of or consented to the merger or
  consolidation of the date that the merger or consolidation has become
  effective; or

       (2)  If the merger or consolidation was approved pursuant to (S)228 or
  253 of this title, the surviving or resulting corporation, either before the
  effective date of the merger or consolidation or within 10 days thereafter,
  shall notify each of the stockholders entitled to appraisal rights of the
  effective date of the merger or consolidation and that appraisal rights are
  available for any or all of the shares of the constituent corporation, and
  shall include in such notice a copy of this section. The notice shall be sent
  by certified or registered mail, return receipt requested, addressed to the
  stockholder at his address as it appears on the records of the corporation.
  Any stockholder entitled to appraisal rights may, within 20 days after the
  date of mailing of the notice, demand in writing from the surviving or
  resulting corporation the appraisal of his shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the appraisal
  of his shares.

  (e)  Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw his demand for
appraisal and to accept the terms offered upon the merger or consolidation.
Within 120 days after the effective date of the merger or consolidation, any
stockholder who has complied with the requirements of subsections (a) and (d)
hereof, upon written request, shall be entitled to receive from the corporation
surviving the merger or resulting from the consolidation a statement setting
forth the aggregate number of shares not voted in favor of the merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of such shares. Such written statement shall
be mailed to the stockholder within 10 days after his written request for such a
statement is received by the surviving or resulting corporation or within 10
days after expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.

  (f)  Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation.  If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list.  The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated.  Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable.  The
forms of the notices by mail 

                                      D-2
<PAGE>
 
and by publication shall be approved by the Court, and the costs thereof shall
be borne by the surviving or resulting corporation.

  (g)  At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights.  The Court may require the stockholders who have demanded
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

  (h)  After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors.  In determining the fair
rate of interest, the Court may consider all relevant factors, including the
rate of interest which the surviving or resulting corporation would have had to
pay to borrow money during the pendency of the proceeding.  Upon application by
the surviving or resulting corporation or by any stockholder entitled to
participate in the appraisal proceeding, the Court may, in its discretion,
permit discovery or other pretrial proceedings and may proceed to trial upon the
appraisal prior to the final determination of the stockholder entitled to an
appraisal.  Any stockholder whose name appears on the list filed by the
surviving or resulting corporation pursuant to subsection (f) of this section
and who has submitted his certificates of stock to the Register in Chancery, if
such is required, may participate fully in all proceedings until it is finally
determined that he is not entitled to appraisal rights under this section.

  (i)  The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto.  Interest may be simple or compound, as the Court
may direct.  Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

  (j)  The costs of the proceeding may be determined by the Court and taxed upon
the parties as the Court deems equitable in the circumstances.  Upon application
of a stockholder, the Court may order all or a portion of the expenses incurred
by any stockholder in connection with the appraisal proceeding, including,
without limitation, reasonable attorney's fees and the fees and expenses of
experts, to be charged pro rata against the value of all the shares entitled to
an appraisal.

  (k)  From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

  (l)  The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.
