   To Alliance Shareholders with registered addresses in the United Kingdom



Dear Shareholder,



                        Recommended offer for Alliance

Introduction

It was announced on 23 July, 1999 that agreement had been reached between your
board and the boards of New Alliance and American Rivers on the terms of a
recommended offer to be made by New Alliance for the whole of the issued share
capital of Alliance.  On 10th August, 1999 a further announcement was made that,
following discussions with the Panel on Takeovers and Mergers, it was
established that, due to the move of Alliance's central management from the UK
to the USA over a period of time, the City Code on Takeovers and Mergers ("City
Code ")no longer applies to Alliance.

This letter, which accompanies the Offer Document issued by New Alliance, sets
out the background to the Offer and the reasons why your directors are
recommending acceptance of the Offer.

The formal offer, which, as indicated above, is not subject to the requirements
of the City Code, is set out on pages 14 to 16 of the Offer Document.

The New Alliance offer
The Offer is being made on the following basis:

1 Share of New Alliance Common Stock for every 1 Alliance Share

and so in proportion for any other number of Alliance Shares held.

The New Alliance Common Stock will be issued credited as fully paid.  It should
be noted that no application will be made for the New Alliance Common Stock to
be admitted to the Official List of the London Stock Exchange or to listing on
any other stock exchange.

The Offer is subject to certain conditions, including the approval of the
shareholders of American Rivers.

The full terms and conditions of the Offer are set out on pages C-1 to C-3 and
Appendix C of the Offer Document.

                                       3

Background to and reasons for the Offer

Dual jurisdiction compliance requirements

Since its merger with LaTex Resources, Inc. in 1997, the holders of a majority
of Alliance's shares have been located primarily in the United States, but its
shares have been traded primarily on the London Stock Exchange.  Following the
issue of Alliance Shares to US shareholders in connection with the merger with
LaTex Resources Inc., Alliance has been required to comply with the securities
requirements of both the United States and the United Kingdom.  The
administrative burden and extra costs and delays created by this dual compliance
requirement have been far greater than the directors of Alliance anticipated and
the level of investor interest in the company in the UK has been less than the
directors of Alliance anticipated.  Consequently, the directors of Alliance have
from time to time considered changing the jurisdiction of the company's
organization and its principal trading market from the UK to the US.

In 1998 Alliance acquired interests in the East Irish Sea, which resulted in the
issue of additional shares and warrants mainly to US investors because the
directors of Alliance and its advisers were unable to generate investor interest
in the UK.  In addition, the dual compliance requirements caused excessive
delays in acquiring these interests, during which time market conditions for the
relevant financial instruments to fund the transaction significantly
deteriorated, ultimately necessitating a reduction by one-half in the size of
the interest acquired.  The directors of Alliance believe that being subjected
to the dual compliance requirements puts Alliance at a distinct competitive
disadvantage to its peer group in the oil and gas industry.

Working capital and refinancing

Alliance Shareholders will have seen from Alliance's 1999 annual report and
accounts posted on 16 September, 1999 that the Alliance Group continues to make
losses, has negative cash flows, has substantial capital commitments and
continues to experience working capital deficits.  Its continuation as a going
concern is, therefore, dependent upon its ability to generate sufficient cash
flows to meet its obligations on a timely basis, to continue to comply with the
terms of its borrowing agreements, to ultimately attain profitability and, most
importantly, to obtain such additional financing or refinancing as will be
required within the foreseeable future.  The directors of Alliance have a
business plan which they believe will, if successfully executed, achieve these
objectives.  However, the achievement of the plan will require, inter alia, that
further financing or refinancing is obtained.  In the opinion of the directors
of Alliance, the most likely source of this finance is from entities in the USA
and this is more likely to be accessed if New Alliance becomes domiciled in the
USA.  For this reason and because Alliance's executive officers, the holders of
a majority of its shares and a significant portion of its properties are located
in the US, the directors of Alliance believe that it would be in the best
interests of Alliance and its shareholders for the group's parent company to be
incorporated in the US rather than the UK and for Alliance's listing on the
London Stock Exchange to be canceled.

Migration to the USA

The directors of Alliance have determined that the most appropriate method for
achieving a change of jurisdiction to the US is for a US company to make an
offer to acquire all of the issued shares of Alliance in exchange for shares in
the US company.  However, the directors of Alliance were unable to identify a
potential offeror whose shares would, in their view, provide an attractive
investment for Alliance Shareholders.  Therefore, the directors of Alliance have
concluded that the most suitable offeror would be a company that has no
substantial assets and whose shareholders would retain only a small investment
in the resulting entity, so that Alliance Shareholders would not be
significantly diluted by the transaction. On reaching this conclusion, the
directors of Alliance identified and approached American Rivers as a potential
offeror for the Alliance Shares.

American Rivers, the common stock of which is currently quoted on the US OTC
Bulletin Board under the symbol "AROC ", is an independent oil and gas
exploration and production company located in Denver, Colorado that has
historically engaged in the acquisition, development and exploration of oil and
gas properties.  In the past two financial years American Rivers has sold
virtually all of its oil and gas properties to repay existing obligations and
accordingly has no significant assets or liabilities.

American Rivers is incorporated in the US State of Wyoming.  However, the
directors of Alliance believe that it is preferable for the company to be
incorporated in Delaware rather than Wyoming for several reasons.  For many
years, Delaware has followed a policy of encouraging incorporation in that state
and, in furtherance of that policy, has adopted

                                       4
<PAGE>

comprehensive, modern and flexible corporate laws that are periodically updated
and revised to meet changing business needs. As a result, many major US
corporations have initially chosen Delaware for their domicile or have
subsequently reincorporated in Delaware. The Delaware courts have developed
considerable expertise in dealing with corporate issues and a substantial body
of case law has developed construing Delaware law and establishing public
policies with respect to Delaware corporations, thereby providing greater
predictability with respect to legal affairs. Accordingly, American Rivers will
be merged into a newly incorporated subsidiary of New Alliance, which is itself
a newly incorporated company formed for the purpose of making the Offer. The
principal activities of New Alliance will be the acquisition, exploration,
development and production of oil and gas properties in the USA and
internationally.

The boards of directors of American Rivers and Alliance agreed that, following
completion of the Offer (on the basis of full acceptance), the Alliance
shareholders should hold 98%and the American Rivers shareholders should hold
2%of New Alliance.  Although American Rivers has no substantial assets, the
boards believe that because the structure of American Rivers facilitates the
change of the Alliance shareholders' investment from the UK to the US, the
shareholders of American Rivers should receive 2%of the resulting entity.

Implications of change of jurisdiction

The rights of shareholders in New Alliance, a US company registered in the State
of Delaware, will differ in various respects from the existing rights of
Alliance Shareholders.  The attention of Alliance Shareholders is drawn to the
sections entitled "comparative rights of shareholders "and "anti-takeover
provisions of Delaware Law and of the organizational documents of New Alliance
"set out on pages 26 to 36 and pages 36 to 38 respectively of the Offer
Document.  In particular, Alliance Shareholders should note that there are no
rights of pre-emption on issues of shares enshrined in Delaware Law and that the
right of shareholders to remove a director from office is more restrictive under
Delaware Law than under English Law.

Management Structure

Immediately following the Offer becoming or being declared unconditional in all
respects the current directors and executive officers of Alliance will become
the directors and executive officers of New Alliance.   The remuneration of such
directors and executive officers is not expected to be affected by the Offer.
The current directors and officers of American Rivers and New Alliance will
resign without compensation.

Delisting

The attention of Alliance Shareholders is drawn to the procedure for cancelling
the listing of Alliance Shares set out in paragraph 15 of the attached letter
from New Alliance.

Action to be taken

The procedure for acceptance of the Offer is set out on pages D-1 to D-3 and
Appendix D of the Offer Document.  To accept the Offer please return your
completed Form of Acceptance, whether or not your Alliance Shares are in CREST,
in accordance with these instructions as soon as possible and in any event so as
to be received by no later than 3:00 p.m. London time on 19 November, 1999.


If you are in any doubt as to the action you should take, you are recommended to
seek immediately your own personal financial advice from your stockbroker, bank
manager, accountant or other independent financial adviser duly authorized to
give you advice.

Recommendation

The directors of Alliance consider that the migration of Alliance to the USA by
means of the Offer is crucial to the future of Alliance.  Consequently, the
board of Alliance, which has been advised by Williams de Broe, considers that
the Offer is in the best interests of Alliance and its shareholders taken as a
whole.  Accordingly the directors of Alliance unanimously recommend Alliance
Shareholders to accept the Offer, as they intend to do in respect of their
aggregate holdings of 389, 484 Alliance Shares, representing approximately
0.8%of the issued share capital of Alliance.  In providing its advice, which is
given to the board of Alliance solely for the purpose of the recommendation of
the Offer by the directors of Alliance to Alliance Shareholders with registered
addresses in the United Kingdom, Williams de Broe has taken into account the
commercial assessments of the directors of Alliance.

Yours sincerely
Jak Keenan
Chairman

The boards of directors of New Alliance, American Rivers and Alliance determined
that it was appropriate that, following completion of the Offer (on the basis of
full acceptance) and the merger of American Rivers with a wholly owned
subsidiary of New Alliance, Alliance Shareholders should hold 98% and
shareholders of American Rivers should hold 2% of the issued common stock of New
Alliance. Although American Rivers has no substantial assets, the boards believe
that because the structure of American Rivers facilitates the change of
jurisdiction of Alliance from the UK to the USA, the shareholders of American
Rivers should own 2% of the resulting entity.

exercise of options granted under the Alliance Share Option Schemes.  It is
assumed that no options will be exercised as the current value of the Offer is
substantially less than the exercise prices of the options.

                                       7

In connection with its acquisition of its U.K. interests in 1998, Alliance
issued to the sellers of the U.K. interests restricted voting shares convertible
into 10,000,000 Alliance Shares and a contingent right to acquire up to
10,000,000 additional Alliance Shares over the next five years.  New Alliance
and the sellers of the U.K. interests have entered into an agreement providing
that New Alliance will issue to the sellers 10,000,000 convertible restricted
voting shares which may be converted into up to 20,000,000 shares of New
Alliance's common stock (on a similar basis to the conversion rights of the
Alliance restricted voting shares).  The convertible restricted voting shares of
new Alliance will confer on the holders equivalent economic and voting rights to
the rights they currently hold in Alliance.  The number of shares of common
stock that would be actually issued as a result of this contingent right will
depend on the sales production actually achieved from, or the estimated value
attributable to, the U.K. interests.  The sellers would receive 5,000,000 shares
if none of the production targets or reserve values are achieved, 20,000,000
shares if all the production targets or reserve values are achieved and will
receive a number of shares within this range if only some of the production
targets or reserve valuations are achieved.  The convertible restricted voting
shares are entitled to one-half vote per share and to vote with the common stock
on all matters.  In addition, the holders of the convertible restricted voting
shares may elect one director to New Alliance's board of directors, who will
then be subject to re-election in the same manner as other directors.

Alliance has in issue warrants to subscribe for 5,079,149 ordinary shares of 1p
each.  The holders of all the warrants have agreed that upon the offer becoming
unconditional, they will exchange such warrants for equivalent warrants to
subscribe for the same number of shares of New Alliance Common Stock.

Alliance has outstanding loan notes convertible into 1,193,581 ordinary shares
of 1p each.  The holder of all the loan notes has agreed that upon the Offer
becoming unconditional it will convert the loan notes into warrants to subscribe
for 1,193,581 shares of New Alliance Common Stock, exercisable at the same times
and at the same subscription price as the loan notes.  The effect of this is
that the holder of the loan notes is waiving its right to receive the face value
of the loan notes.

11.  New Alliance Common Stock

The New Alliance Common Stock will be issued free from all liens, equities,
charges, encumbrances and other interests. The New Alliance Common Stock will be
issued credited as fully paid.  No application will be made for the New Alliance
Common Stock to be admitted to the Official List of the London Stock Exchange or
to listing on any other stock exchange.

It is anticipated that, following the Offer becoming unconditional, the New
Alliance Common Stock will be quoted on the OTC Bulletin Board in the USA.  The
OTC Bulletin Board is a regulated quotation service that displays real-time
quotes, last-sale prices, and volume information in over-the-counter equity
securities, which are securities that are not listed or traded on a national
securities exchange or the NASDAQ Stock Market.  OTC Bulletin Board securities
are traded by market makers that enter quotes and trade reports through a closed
computer network.

12.  Procedure for acceptance of the Offer

The procedure for acceptance of the Offer is set out on pages D-1 to D-3 and
Appendix D of the Offer Document and in the Form of Acceptance.

13.  Taxation

Your attention is drawn to pages 18 to 26 of the Offer Document.

United Kingdom taxation

The following paragraphs, which are intended as a general guide only, are based
on current UK legislation and Inland Revenue practice.  They summarize certain
limited aspects of the UK tax treatment of acceptance of the Offer, and they
relate only to the position of validly accepting shareholders who hold their
Alliance Shares as an investment and who are resident or ordinarily resident in
the UK for taxation purposes and who are not resident in any other territory.
If you are subject to taxation in any other jurisdiction, or are in any doubt as
to your taxation position you should consult an appropriate adviser without
delay.

                                       8
<PAGE>

Taxation of capital gains

(a)  A holder of Alliance Shares who, either alone or together with persons
     connected with him, does not hold more than 5% of Alliance Shares will not
     be treated as making a disposal for the purposes of United Kingdom capital
     gains as a consequence of receiving new shares in New Alliance Common Stock
     in exchange for his Alliance Shares.  Any gain or loss which would
     otherwise have arisen on a disposal by such holder of his Alliance Shares
     will be "rolled over "into his New Alliance Common Stock.  The New Alliance
     Common Stock will be treated as the same asset as his Alliance Shares
     acquired at the same time and for the same consideration as he acquired his
     Alliance Shares.

(b)  A holder of Alliance Shares who, either by himself or with persons
     connected with him, holds more than 5% thereof may or may not also be
     treated in the same way as one holding 5% or less.

(c)  A subsequent disposal of New Alliance Common Stock received in exchange for
     Alliance Shares may, depending on individual circumstances, give rise to a
     liability to United Kingdom taxation of capital gains.

(d)  A UK resident who is domiciled within the UK and is a participator in a
     non-UK resident company which would be "close" if it were UK resident and
     which holds Alliance Shares will have attributed to him a proportion of any
     gain realized by the company as a consequence of receiving New Alliance
     Common Stock in exchange for Alliance Shares, or, where any gain is "rolled
     over" into New Alliance common stock, on disposal of that stock, unless his
     share of such gain does not exceed 5% thereof.

(e)  A UK resident settlor or UK resident and domiciled beneficiary of a trust
     which is not resident in the UK for capital gains tax purposes and holds
     Alliance Shares or is a participator in a non-resident company which would
     be close if it were resident in the UK and which holds Alliance Shares may
     in certain circumstances be chargeable on any gain realized as a
     consequence of the trust or company receiving New Alliance Common Stock in
     exchange for Alliance Shares or, except in the case of a settlor who is not
     domiciled in the UK, where any gain is "rolled over" into New Alliance
     Common Stock, on disposal of that common stock.

Stamp duty and stamp duty reserve tax

No stamp duty or stamp duty reserve tax will be payable by validly accepting
shareholders as a result of accepting the Offer.

Other taxation matters

Special provisions may apply to Alliance Shareholders who have acquired or
acquire their Alliance Shares by exercising options under any share schemes,
including provisions imposing a charge to income tax.

14.  Settlement, listing and dealings

Your attention is drawn to pages D-1 to D-3 of Appendix D to the Offer Document.

15.  Delisting

If New Alliance receives acceptances in respect of 90% or more of Alliance's
issued share capital, New Alliance intends to pursue a process of compulsory
acquisition of the remaining Alliance Shares under sections 429 -430F of the
Companies Act 1985.  New Alliance also intends to cause Alliance to apply to the
London Stock Exchange for the delisting of the Alliance Shares when the Offer
has been declared or becomes wholly unconditional.  In these circumstances the
date on which the cancellation of the listing would take effect would be
specified in the announcement that the Offer is wholly unconditional, and such
date would be at least 20 clear business days following the date of that
announcement.

16.  Further information

Your attention is drawn to the further information contained in the Appendix to
this document and to the accompanying Offer Document.

any event, so as to be received by post or by hand by IRG plc, Balfour House,

ALLIANCE RESOURCES PLC                          AMERICAN RIVERS OIL COMPANY

                               October 21, 1999


To shareholders of Alliance Resources PLC and American Rivers Oil Company:

     The Boards of Directors of Alliance Resources and American Rivers are
proposing that American Rivers change its state of incorporation from Wyoming to
Delaware by merging into the subsidiary of a new Delaware holding company and
that the new Delaware holding company offer to acquire all of the shares of
Alliance Resources PLC. If we complete these transactions, American Rivers
shareholders and Alliance shareholders who accept the offer will own shares in a
new Delaware corporation , the subsidiaries of which will own all of the assets
now owned by Alliance Resources PLC and American Rivers Oil Company. After the
reincorporation, the new company will be named AROC Inc. and we refer to that
company as it will exist after the transactions as new Alliance.

     If all of the shareholders of Alliance accept the offer, they will own 98%
of the shares of the new company and the present shareholders of American Rivers
will own approximately 2% of the total shares of the new company. The Board of
Directors and executive officers of the new company will be the same as the
current Board of Directors and executive officers of Alliance.

     American Rivers common stock is currently quoted on the OTC Bulletin Board
under the symbol "AROC." Alliance's shares are currently traded on the Official
List of the London Stock Exchange under the "ARS" symbol. After these
transactions, we expect that the shares of the new Alliance will be quoted on
the OTC Bulletin Board, but we cannot assure you that there will be any
substantial trading volume for the stock.

     The Board of Directors of American Rivers has unanimously recommended that
the American Rivers shareholders vote in favor of the reincorporation. Because
the offer for Alliance Resources PLC will be made by the new Delaware company,
the American Rivers shareholders are not being asked to vote on the offer
itself. The directors of American Rivers, who directly or indirectly control
approximately 53.5% of the outstanding shares of the company, have indicated
that they intend to vote for the approval of the reincorporation. Therefore,
approval of the reincorporation is assured and we are not asking American Rivers
shareholders for a proxy.

     American Rivers has called a special meeting of the shareholders to vote on
the reincorporation. The record date for voting at the meeting is October 12,
1999. The meeting will be held November 18, 1999.

     The Board of Directors of Alliance has unanimously recommended that all
Alliance shareholders accept the offer as each of the Board members intend to do
in respect of their holdings of Alliance shares, which total 389,484 Alliance
ordinary shares representing 0.82% of the outstanding ordinary shares of
Alliance.

     Alliance shareholders who wish to accept the offer should ensure that they
return their completed Form of Acceptance in the enclosed postage paid envelope
as soon as possible and in any event so as to be received by no later than 3:00
p.m. on November 19, 1999.

     This document contains more complete information about the reincorporation
of American Rivers and the offer for the Alliance shares. You should read this
entire document carefully, including the Annual Reports on Form 10-K for both
Alliance and American Rivers. It is first being mailed on October 21, 1999.

     See "Risk Factors," beginning on page 7 for a discussion of certain risks
relating to the transactions and the ownership of new Alliance common
stock.

     Neither the Securities and Exchange Commission nor any State Securities
Commission has determined if this information statement is truthful or complete.
Any representation to the contrary is a criminal offense.

     Sincerely,                            Sincerely,

     JOHN A. KEENAN,                       KARLTON TERRY,
     Chairman and Managing Director        President and Chief Executive Officer
     Alliance Resources PLC                American Rivers Oil Company

The Proposed Transactions

  The Board of Directors of American Rivers has proposed that American Rivers
change its state of incorporation from Wyoming to Delaware by merging into the
subsidiary of a newly formed Delaware company.  In the reincorporation, each
shareholder of American Rivers will receive .11 shares of the new Delaware
company for each share of common stock or Class B common stock of American
Rivers that the shareholder now owns. Therefore, the relative ownership of the
American Rivers' shareholders among themselves will not change.

  The new Delaware company will make an offer to the shareholders of Alliance to
acquire all of the outstanding shares of Alliance on the basis of one share of
the new company's common stock for each ordinary share of Alliance they now
hold. The Board of Directors of Alliance has recommended that the Alliance
shareholders accept the offer.  When the reincorporation and the offer are
completed, if all of the Alliance shareholders accept the offer, the Alliance
shareholders will own 98% of the new company, and the American Rivers
shareholders will own 2% of the new company.  The individuals that were
directors and officers of Alliance will be the directors and officers of the new
company.

Reasons for the Transactions

  The Board of Directors of American Rivers has proposed the reincorporation in
connection with a proposal by the new Delaware company to make an offer to
acquire all of the outstanding shares of Alliance.  Management of American
Rivers believes that a combination of American Rivers with Alliance is in the
best interests of the American Rivers shareholders because it will permit them
to have a continuing interest in a company with substantial assets.

                                       1
<PAGE>



  The Board of Directors of Alliance believes that the proposed combination with
American Rivers is in the best interests of the Alliance shareholders.  The
administrative burden and extra costs created by complying with the securities
requirements of both the United States and the United Kingdom have been far
greater than the Directors of Alliance anticipated and the level of investor
interest in Alliance in the U.K. has been less than the Directors of Alliance
anticipated.

  The achievement of Alliance's business plan will require that further
financing or refinancing is obtained.  In the opinion of the Directors of
Alliance, the most likely source of this finance is from entities in the U.S.
and this is more likely to be accessed if new Alliance is domiciled in the U.S.


  Because Alliance's executive officers, the holders of a majority of its shares
and a significant portion of its properties are located in the U.S., the
Directors of Alliance believe that it would be in the best interests of Alliance
and its shareholders for the parent company to be incorporated in the U.S.
rather than the U.K.  They also believe that it is desirable for the U.S.
company to be incorporated in the State of Delaware to take advantage of the
benefits afforded by Delaware corporate laws.

Voting by American Rivers Shareholders

  A special meeting of the American Rivers shareholders will be held on November
18, 1999, at the offices of American Rivers, 700 East Ninth Avenue, Suite 106,
Denver, Colorado 80203 (or at any adjournments or postponements thereof) to
consider and vote on the proposal to approve the reincorporation and any other
matters that may properly come before such meeting. The presence, in person or
by proxy, of shareholders holding a majority of the outstanding shares of
American Rivers common stock and Class B Common Stock, in the aggregate, will
constitute a quorum. Only those shareholders of record at the close of business
on October 12, 1999, as shown in the records of American Rivers, will be
entitled to vote or to grant proxies to vote at the special meeting.

  Approval of the reincorporation requires the affirmative vote of the
shareholders of American Rivers holding at least a majority of the outstanding
shares of American Rivers common stock and Class B Common Stock, voting as a
single class.  As of October 12, 1999, there were 3,565,770 shares of American
Rivers common stock and 7,267,820 shares of American Rivers Class B Common Stock
outstanding and entitled to vote. The directors and executive officers of
American Rivers and their affiliates directly owned, in the aggregate, 5,795,967
shares (approximately 53.5%) of the total number of shares of American Rivers
common stock and Class B Common Stock outstanding at the record date. These
persons have indicated that they will vote all of their shares of American
Rivers common stock and Class B Common Stock for the approval of the
reincorporation.  Therefore, American Rivers is not soliciting proxies in
connection with the meeting.

American Rivers Shareholders' Exercise of Dissenters' Rights

  If an American Rivers shareholder does not vote in favor of the
reincorporation and complies with the detailed provisions contained in Article
13 of the Wyoming Business Corporation Act, that shareholder will be entitled to
dissent and seek the payment of the fair value of the shares of American Rivers.
A copy of Article 13 of the Wyoming Business Corporation Act is reproduced as
Appendix B to this document.  American Rivers shareholders who wish to dissent
should read those materials carefully.  If an American Rivers shareholder votes
for the reincorporation, the shareholder will waive the dissenters' rights.  If
the shareholder votes against the reincorporation without otherwise complying
with the additional notice and other provisions of Article 13 of the Wyoming
Business Corporation Act, the shareholder will not effectively exercise
dissenters' rights.

Recommendation To American Rivers Shareholders

  The American Rivers board of directors has approved the merger agreement and
recommends that shareholders of American Rivers vote FOR approval of the
reincorporation.

Procedure for Acceptance of the offer by Alliance Shareholders

  In order to accept the proposed offer to exchange shares, Alliance
shareholders must complete, execute, have witnessed and return a form or forms

                                       2
<PAGE>


to Registrar and Transfer Company as forwarding agent at 10 Commerce Drive,
Cranford, NJ 07016 if your registered address is in the United States or Canada,
no later than 3 p.m. (London time) on November 19, 1999. Separate forms of
acceptance should be completed for holdings in certificated and uncertificated
form, holdings in uncertificated form under different member account IDs and

witnessed form of acceptance. If Alliance shares are in uncertificated form,
Alliance shareholders should send, or arrange for a sponsor to send, properly
authenticated and completed instructions to CRESTCo to settle in CREST the
necessary details related to the exchange. For a more detailed account of the
offer acceptance procedures for Alliance shareholders, refer to "Procedure for
Acceptance of the Offer," included as Appendix D to this document.

Recommendation to Alliance Shareholders

  The directors of Alliance unanimously recommend that all Alliance shareholders
accept the offer, as they intend to do in respect of their aggregate holdings of
Alliance shares, which  total 389,484 Alliance shares representing 0.82% of the
outstanding ordinary shares of Alliance.

Material United States Federal Tax Consequences of the Merger and Exchange

  This section summarizes the material United States federal income tax
consequences to you of the transactions. As summary information is by its nature
less precise and detailed, you are encouraged to carefully read the discussions
under "Material Tax Consequences of the Merger and Exchange."  In addition,
although this summary and the more detailed discussion under "Material Tax
Consequences of the Merger and Exchange" does address certain tax consequences
to the shareholders of American Rivers and Alliance in general, it does not
address all aspects of taxation that may be relevant to your individual
circumstances.  You are encouraged to consult with your own tax advisor for
information on how the transactions will impact you based on your individual
circumstances.

  Tax Treatment of the Merger.  We have structured the merger of American Rivers
into a subsidiary of new Alliance to be tax-free to American Rivers, new
Alliance,  the subsidiary of new Alliance into which American Rivers will merge
and you for United States federal income tax purposes if you are a U.S.
Shareholder unless you exercise your dissenters' rights.  The subsidiary of new
Alliance into which American Rivers will merge should have a tax basis and
holding period in the assets of American Rivers equal to American Rivers' tax
basis and holding period in those assets before the merger.  American Rivers'
U.S. shareholders should not recognize any gain or loss for United States
federal income tax purposes on the exchange of their American Rivers stock for
stock in new Alliance as a result of the merger.

  Tax Treatment of the Exchange of Alliance Shares in the Offer.  We have
structured the offer to be tax-free to you for United States federal income tax
purposes if you accept the offer and are either a Non-U.S. Shareholder or you
are a U.S. Shareholder and shareholders owning at least 80 percent of the total
combined voting power of all of Alliance's classes of stock entitled to vote
exchange their shares pursuant to the offer.  If the exchange of the ordinary
shares of Alliance in the offer is tax-free to you, your tax basis and holding
period in the shares of new Alliance common stock you receive should be the same
as your tax basis and holding period of your current ordinary shares of
Alliance.

Material U.K. Tax Consequences of the Exchange

  We expect the exchange of Alliance ordinary shares for new Alliance common
stock in the offer to be tax-free to you for U.K. capital gains purposes if you
own less than 5 percent of the Alliance ordinary shares.

How the Transactions Will Affect Your Rights as a Shareholder

  The rights of shareholders under Delaware law differ from the rights of
shareholders under U.K. and Wyoming law.  For a detailed comparison of these
rights, refer to "Comparative Rights of Shareholders" below.

Accounting Treatment of the Transactions

                                       3
<PAGE>

          As a result of the Alliance shareholders owning approximately 98% of
the combined company, Alliance will be treated as having acquired American
Rivers for accounting purposes.  Alliance will treat the business combination as
an issuance of securities.

                                 RISK FACTORS

     In addition to the other information presented in this document you should
carefully consider the following risk factors in deciding how to vote on the
reincorporation or whether to accept the offer.

There are a number of risks associated with the transactions

     The anti-takeover provisions in new Alliance's organizational documents may
have the effect of discouraging a change in ownership or management.

     Some of the provisions of Delaware law and of new Alliance's certificate of
incorporation may discourage a third party from making an acquisition proposal
for new Alliance, and may inhibit a change of control of new Alliance under
circumstances that could give you an opportunity to realize a premium over then-
prevailing market prices.  Furthermore, your ability to change the management of
new Alliance could be substantially impeded by these provisions.  For a more
complete discussion of these risks, see "Anti-Takeover Provisions of Delaware
Law and of the Organizational Documents of New Alliance."

     The uncertainty of reserve information and future net revenue estimates
makes it difficult to predict what new Alliance's reserves or future net
revenues will be.

     There are numerous uncertainties inherent in estimating oil and gas
reserves and their values.  Although we believe the reserve estimates contained
in this document are reasonable, reserve estimates are imprecise and are
expected to change as additional information becomes available.  For a more
complete discussion of these uncertainties, see "Item 2. Properties." in the
Alliance Form 10-K included in this document.

     United States or United Kingdom taxes may be incurred by you or the
involved entities.

     We believe the reincorporation merger will qualify as a tax-free
reorganization for the involved entities and certain of their shareholders.  We
also believe that the exchange of ordinary shares of Alliance in the offer will
qualify as a tax-free reorganization under U.S. law for the involved entities,
non-U.S. Shareholders and U.S. Shareholders if shareholders owning at least 80
percent of the total combined voting power of all of Alliance's classes of stock
entitled to vote exchange their shares pursuant to the offer.  We have not
asked, however, nor do we intend to ask, for a ruling from the Internal Revenue
Service that the reincorporation merger and exchange will qualify as tax-free
reorganizations. There is always a risk that the Internal Revenue Service's
interpretation of the reorganizations transactions could be unfavorable.

     We also believe that a holder of ordinary shares of Alliance who, either
alone or together with persons connected with him, does not hold more than 5% of
the ordinary shares of Alliance will not be treated as making a disposal for
United Kingdom capital gains tax purposes as a consequence of receiving new
shares in new Alliance in exchange for his ordinary shares of Alliance. We have
not asked, however, nor do we intend to ask, for a ruling from the Inland
Revenue concerning these matters. There is always a risk that the Inland
Revenue's interpretation of the transaction could be unfavorable.

     New Alliance has not paid dividends on its common shares in the past and
does not expect to pay dividends in the foreseeable future.  If new Alliance
were to pay dividends to its non-U.S. Shareholders, they would be subject to
United States withholding taxes.  If a dividend was paid to a United States
trade or business, it would be subject to the regular United States federal
income tax.  You may also be subject to "backup withholding" at rates of up to
31% on dividends on the sale or exchange of new Alliance unless you meet
certain specified exceptions or exemptions.  If an amount is withheld in this
manner, it serves as a credit against your United States federal income tax
liability.

     There is also a tax on U.S. Shareholders in the exchange of ordinary shares
of Alliance in the offer if Alliance is determined to be a Passive Foreign
Investment Corporation, known as a "PFIC".  This would cause certain U.S.
Shareholders to recognize ordinary income or loss on the exchange.  We do not
believe that this tax applies.  We have not asked, and do not intend to ask, for
a ruling from the Internal Revenue Service addressing whether this tax applies.
In addition, we have not asked for a tax opinion as to whether each individual
shareholder would be subject to this tax.  For a more detailed explanation of
the tax consequences to shareholders under the PFIC rules, read the discussion
under "Material Tax Consequences of the Exchange-The Exchange-U.S. Shareholders-

Investment Company Considerations".


     Alliance is currently highly leveraged.  Following the consolidation new
Alliance will also be highly leveraged.

     After the consolidation, new Alliance will have approximately $59 million
of long-term debt.  This level of debt will have several important effects on
its future operations, including:

     .    a substantial portion of its cash flow from operations must be
          dedicated to the payment of interest on its debt and will not be
          available for other purposes;
     .    covenants contained in its credit facilities will require it to meet
          a number of financial tests;
     .    other restrictions may limit its ability to borrow additional funds
          or to dispose of assets and may affect its flexibility in planning
          for, and reacting to, changes in its business, including possible
          acquisition activities; and
     .    its ability to obtain additional financing in the future for working
          capital, capital expenditures, acquisitions, general corporate
          purposes or other purposes may be impaired.

     New Alliance may be unable to continue as a going concern

     Alliance continues to experience net losses and working capital deficits.
These factors may indicate new Alliance will be unable to continue as a going
concern for a reasonable period of time.  New Alliance's continuation as a going
concern is dependent upon its ability to generate sufficient case flow to meet
its obligations on a timely basis, to continue to comply with the terms of its
borrowing agreements, to obtain additional financing or refinancing as will be
required and ultimately to attain profitability.

There are a number of risks inherent in the oil and gas business

     New Alliance's success might be adversely affected by the volatility of oil
and gas prices.

     New Alliance's revenues, profitability, future growth and ability to borrow
funds or obtain additional capital, as well as the carrying value of its
properties, will be substantially dependent upon prevailing prices of oil and
gas.  Historically, the markets for oil and gas have been volatile, and they are
likely to continue to be volatile in the future.  Prices for oil and gas may
fluctuate widely in response to relatively minor changes in the supply of and
demand for oil and gas, market uncertainty and a variety of additional factors
that are beyond new Alliance's control.

     It is impossible to predict future oil and gas price movements with
certainty.  Declines in oil and gas prices may materially adversely affect new
Alliance's financial condition, liquidity, ability to finance planned capital
expenditures and results of operations.  Lower oil and gas prices also may
reduce the amount of oil and gas that new Alliance can produce economically.

     Oil and gas price hedging and financial hedging arrangements may expose new
Alliance to financial loss in some circumstances.

     In order to reduce its exposure to short-term fluctuations in the prices of
oil and gas, Alliance periodically has entered into hedging arrangements.  The
hedging arrangements apply to only a portion of its production and provide only
partial price protection against declines in oil and gas prices.  These hedging
arrangements will remain in place following the transactions and may expose new
Alliance to risk of financial loss in some circumstances, including instances
where production is less than expected or where the other party to any hedging
arrangement fails to perform.  In addition, the hedging arrangements may limit
the benefit to new Alliance of increases in the prices of oil or gas.

     Significant capital needs may require that new Alliance obtain additional
financing.

     Due to its plans for active acquisition, development and exploration
programs, Alliance has experienced, and new Alliance expects to experience,
substantial capital needs.  As a result, additional financing may be required in
the future to fund new Alliance's growth and developmental and exploratory
drilling.  We cannot assure you as to the

                                       8
<PAGE>

availability or terms of any such additional financing that may be required or
whether financing will continue to be available under existing or new credit
facilities. If sufficient capital resources are not available to new Alliance,
its drilling and other activities may be curtailed.

     New Alliance's reserves are concentrated in a few fields

     We estimate that new Alliance will receive approximately 40% of its total
estimated year 2000 production from its interests in the East Irish Sea.  Any
interruption in the production from these wells could materially adversely
affect the operations of new Alliance.

     There are numerous risks relating to drilling activities.

     New Alliance's success will be materially dependent upon the continued
success of its drilling program. Oil and gas drilling involves numerous risks,
including the risk that no commercially productive oil or gas reservoirs will be
encountered.  The cost of drilling, completing and operating wells is often
uncertain, and drilling operations may be curtailed, delayed or canceled as a
result of a variety of factors, including, unexpected drilling conditions,
pressure or irregularities in formations, equipment failures or accidents,
adverse weather conditions, compliance with governmental requirements, and
shortages or delays in the availability of drilling rigs and the delivery of
equipment.  New Alliance's future drilling activities may not be successful and,
if drilling activities are unsuccessful, such failure will have an adverse
effect on new Alliance's future results of operations and financial condition.
Although new Alliance has identified numerous drilling prospects, we cannot
assure you that those prospects will be drilled or that oil or gas will be
produced from any such identified prospects or any other prospects.

     Risks relating to the acquisition of oil and gas properties may affect new
Alliance's future success.

     The successful acquisition of producing properties requires an assessment
of recoverable reserves, future oil and gas prices, operating costs, potential
environmental and other liabilities and other factors.  Such assessments are
necessarily inexact and their accuracy inherently uncertain.  In connection with
such an assessment, new Alliance will perform a review of the subject properties
that it believes to be generally consistent with industry practices.  This
usually includes on-site inspections and the review of reports filed with
various regulatory entities. Such a review, however, will not reveal all
existing or potential problems, nor will it permit a buyer to become
sufficiently familiar with the properties to fully assess their deficiencies and
capabilities.  Inspections may not always be performed on every well, and
structural and environmental problems are not necessarily observable even when
an inspection is undertaken.  Even when problems are identified, the seller may
be unwilling or unable to provide effective contractual protection against all
or part of these problems.  We cannot assure you that any acquisition of
property interests by new Alliance will be successful and, if an acquisition is
unsuccessful, that the failure will not have an adverse effect on new Alliance's
future results of operations and financial condition.

     There are a number of hazards relating to well operations, and new Alliance
does not insure against all of them.

     The oil and gas business involves numerous operating hazards, such as well
blowouts, craterings, explosions, uncontrollable flows of oil, gas or well
fluids, fires, formations with abnormal pressures, pollution, releases of toxic
gas, and other environmental hazards and risks.  Any of these could result in
substantial losses to new Alliance. New Alliance will not be fully insured
against these events either because insurance is not available or because new
Alliance will elect not to insure against them because of prohibitive premium
costs.  While new Alliance intends to maintain all types of insurance commonly
maintained in the oil and gas industry, it does not maintain business
interruption insurance.  In addition, new Alliance cannot predict with certainty
the circumstances under which an insurer might deny coverage. If an event not
fully covered by insurance occurs, it could have a material adverse effect on
new Alliance's financial condition and results of operations.

     The Year 2000 problem poses risks.

     The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, some normal business activities or operations.
This risk exists both as to the information technology systems such as
computers, programs and related systems and non-information technology systems
such as embedded technology on a silicon chip, as well as to the systems of
third parties.  Such failures could materially and adversely affect new

                                       9
<PAGE>

Alliance's results of operations, cash flow and financial condition.  Due to the
general uncertainty inherent in the Year 2000 problem, resulting in part from
the uncertainty of the Year 2000 readiness of third party suppliers, vendors and
transporters, we are unable to determine at this time whether the consequences
of Year 2000 failures will have a material impact on results of operations, cash
flow or financial condition.  Although it is currently not possible to determine
the consequences of Year 2000 failures, the current assessment is that new
Alliance's areas of greatest potential risk are in connection with the
transporting and marketing of the oil and gas production.  Alliance is
contacting the various purchasers and pipelines with which it regularly does
business to determine their state of readiness for the Year 2000.  Although the
purchasers and pipelines will not guaranty their state of readiness, the
responses received to date have indicated no material problems.  New Alliance
believes that in a worse case scenario, the failure of its purchasers and
transporters to conduct business in a normal fashion could have a material
adverse effect on cash flow for a period of six to nine months.  The evaluation
of third party readiness will be followed by the development of contingency
plans.

                FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE

     Some statements contained or incorporated by reference in this document
regarding future financial performance and results and other statements that are
not historical facts are "forward-looking statements."  The words "expect,"
"project," "estimate," "predict," "anticipate," "believes" and similar
expressions are also intended to identify forward-looking statements.  Such
statements, new Alliance's results and the price of its shares may be affected
by numerous risks, uncertainties and assumptions, including but not limited to:

     .  changes in general economic conditions in the United States or the
        United Kingdom;

     .  changes in law and regulations to which new Alliance is subject;

     .  the level of investor interest in and trading activity of Alliance's
        shares;

     .  the cost and effects of legal and administrative claims and proceedings
        against new Alliance or its subsidiaries or which may be brought against
        new Alliance or its subsidiaries;

     .  conditions in the capital markets utilized by new Alliance to access
        capital to finance operations;

     .  energy prices;

     .  competition from other oil and gas producers and alternate fuels;

     .  the ability of new Alliance to sustain its past practice of growth
        through acquisitions;

     .  the general level of natural gas and petroleum product demand and
        weather conditions, among other things; and

     .  the general uncertainty inherent in the Year 2000 problem resulting in
        part from the Year 2000 readiness of third parties and the
        interconnection of computer systems.

                           THE PROPOSED TRANSACTIONS

Background of the Reincorporation Proposal and Offer

     Since its merger with LaTex Resources, Inc. in 1997, the holders of a
majority of Alliance's shares have been located primarily in the United States,
but its shares have been traded primarily on the London Stock Exchange.
Following the issue of Alliance Shares to U.S. shareholders in connection with
the merger with LaTex Resources, Inc., Alliance has been required to comply with
the securities requirements of both the United States and the United Kingdom.
The administrative burden and extra costs and delays created by this dual
compliance requirement has been far greater than the directors of Alliance
anticipated and the level of investor interest in the company in the U.K. has
been less than the directors of Alliance anticipated.  Therefore, the directors
of Alliance have from time to time considered changing the jurisdiction of the
company's organization and its principal trading market from the U.K. to the
U.S.

                                       10
<PAGE>


     In 1998 Alliance acquired interests in the East Irish Sea, which resulted
in the issue of additional shares and warrants to mainly U.S. investors because
the directors of Alliance and its advisers were unable to generate investor
interest in the U.K.  In addition, the dual compliance requirements caused
excessive delays in acquiring these interests, during which time market
conditions for the relevant financial instruments to fund the transaction
significantly deteriorated, ultimately necessitating a reduction by one-half in
the size of the interest acquired.  The directors of Alliance believe that being
subjected to the dual compliance requirements puts Alliance at a distinct
competitive disadvantage to its peer group in the oil and gas industry.


     During fiscal 1998 and 1999, American Rivers sold virtually all of its oil
and gas properties to repay existing obligations. After completing those sales,
American Rivers management determined to pursue a combination with another
company in order to preserve the remaining value of American Rivers for its
shareholders. In March 1998, Royal Scott Minerals, Inc., a wholly owned
subsidiary of a public company, Rackwood, Inc., listed on the London Stock
Exchange, purchased options from Karlton Terry Oil Company, Francarep, Inc.,
Karlton Terry, Jubal Terry, and Art and Music Outreach for Kids with the view to
acquire their shares in connection with a potential transaction. Royal Scott
Minerals elected not to exercise these options, however, and they expired in
September 1998. After the options expired, the principals who granted the
options continued to attempt to negotiate an extension of the options, but the
negotiations terminated late in January 1999 without the options being extended.

     In early May 1999, Alliance management contacted Karlton Terry, the
president of American Rivers, to discuss the possibility of American Rivers
acquiring Alliance on an agreed basis. Mr. Terry and Mr. Keenan, the chief
executive of Alliance, were prior business acquaintances, having been previously
introduced to each other by Mr. Michael Humphries, a director of Alliance. The
parties discussed Alliance's plans and the current status of American Rivers and
concluded that there was sufficient interest on both parts to arrange a formal
meeting. The parties exchanged information and discussed same in several follow-
up telephone conversations.

     Thereafter, Mr. Keenan traveled to Denver to meet with Mr. Terry and other
representatives of American Rivers. Mr. Keenan and Mr. Terry briefed each other
on their respective companies and there followed a detailed discussion of the
cross-border regulatory aspects of a potential offer by American Rivers.
Possible structures of the transaction and terms were discussed. The parties
agreed to discuss the outcome of the meeting with their respective boards of
directors and advisors.

     During this same period Mr. Keenan held meetings with Alliance's lenders
regarding the proposals being discussed and secured their preliminary consent,
subject to final terms and conditions being satisfactory to them, as required by
their agreements with Alliance.

     Alliance and American Rivers continued to exchange information and on June
14, 1999, representatives of the parties met in Phoenix. Mr. Keenan was
accompanied by Mr. Paul Fenemore, a fellow executive and director of Alliance,
and Mr. Terry was accompanied by Mr. Denis Bell, a fellow director of American
Rivers. The parties discussed the final terms of the proposed offer and the
post-transaction ownership by the Alliance shareholders and American Rivers
shareholders. Both parties agreed to meet with their respective boards of
directors as soon as possible to present the proposed transaction and seek their
respective approvals.

     Follow-up telephone conversations took place between Mr. Keenan and Mr.
Terry as final terms and conditions were worked out. Thereafter, on July 7, 1999
and July 21, 1999, the respective boards of directors met and approved each
party entering into an agreement whereby American Rivers would make an offer to
acquire Alliance on the basis that, after the transaction was completed, the
Alliance shareholders would hold 98% and the American Rivers shareholders would
hold 2% of the new company. On July 22, 1999, the parties executed the Exchange
and Merger Agreement formalizing the agreement between them.

Reasons for the Reincorporation and the Offer

     The Board of Directors of American Rivers has proposed the reincorporation
in connection with a proposal to offer to exchange shares of the new Delaware
company for all of the outstanding shares of Alliance. Management of American
Rivers believes that a combination of American Rivers with Alliance is in the
best interests of the American Rivers shareholders because it will permit them
to have a continuing interest in a company with substantial assets.  As a result
of its recent sales of properties, American Rivers has no significant assets,
while Alliance has more than $36 million in assets at April 30, 1999.

                                       11
<PAGE>


     As referred to above, the directors of Alliance believe that being obliged
to comply with the securities requirements of both the United Kingdom and the
United States puts Alliance at a distinct competitive disadvantage to its peer
group in the oil and gas industry.  As a result, Alliance is proposing to change
the company's organization and its principal trading market from the U.K. to the
U.S.

     Alliance Shareholders will see from Alliance's 1999 Annual Report on Form
10-K, included with this document, that Alliance continues to experience net
losses and working capital deficits.  These factors may indicate Alliance will
be unable to continue as a going concern for a reasonable period of time.
Alliance's continuation as a going concern is dependent upon its ability to
generate sufficient cash flow to meet its obligations on a timely basis, to
continue to comply with the terms of its borrowing agreements, to obtain
additional financing or refinancing as will be required and ultimately to attain
profitability.  The directors of Alliance have a business plan which they
believe will, if successfully executed, achieve these objectives.  However, the
achievement of the plan will require, among other things, that further financing
or refinancing is obtained.

     In the opinion of the directors of Alliance, the most likely source of this
financing is from entities in the U.S. and this is more likely to be accessed if
new Alliance is domiciled in the U.S.  For this reason and because Alliance's
executive officers, the holders of a majority of its shares and a significant
portion of its properties are located in the U.S., the directors of Alliance
believe that it would be in the best interests of Alliance and its shareholders
for the parent company to be incorporated in the U.S. rather than the U.K. and
for Alliance's listing on the London Stock Exchange to be cancelled.

     The directors of Alliance have determined that the most appropriate method
to achieve this change is for a U.S. company to make an offer to acquire all of
the outstanding shares of Alliance in exchange for shares in the U.S. company.
However, the directors of Alliance were unable to identify a potential offeror
whose shares would, in their view, provide an attractive investment for Alliance
shareholders.  Therefore, the directors of Alliance have concluded that the most
desirable offeror would be a company that has no substantial assets and whose
shareholders would retain only a small investment in the resulting entity, so
that Alliance shareholders would not be significantly diluted by the
transaction.  On reaching this conclusion, the directors of Alliance identified
and approached American Rivers as a potential offeror for the Alliance shares.


     American Rivers, the common stock of which is currently quoted on the U.S.
OTC Bulletin Board under the symbol "AROC", is an independent oil and gas
exploration and production company located in Denver, Colorado that has
historically engaged in the acquisition, development and exploration of oil and
gas properties.  In the past two financial years American Rivers has sold
virtually all of its oil and gas properties to repay existing obligations and
accordingly has no significant assets or liabilities.

     American Rivers is incorporated in the State of Wyoming.  The directors of
Alliance believe that it is preferable for the company to be incorporated in
Delaware rather than Wyoming for several reasons.  For many years, Delaware has
followed a policy of encouraging incorporation in that state and, in furtherance
of that policy, has adopted comprehensive, modern and flexible corporate laws
that are periodically updated and revised to meet changing business needs.  As a
result, many major corporations have initially chosen Delaware for their
domicile or have subsequently reincorporated in Delaware.  The Delaware courts
have developed considerable expertise in dealing with corporate issues, and a
substantial body of case law has developed construing Delaware law and
establishing public policies with respect to Delaware corporations, thereby
providing greater predictability with respect to legal affairs.  Accordingly,
American Rivers will be merged into a newly incorporated subsidiary of new
Alliance, which is itself a newly incorporated company which was formed for the
purpose of making the offer.  The principal activities of new Alliance will be
the acquisition, exploration, development and production of oil and gas
properties in the U.S. and internationally.

     The Boards of Directors of American Rivers and Alliance determined that it
was appropriate that, after the transactions, the Alliance shareholders should
hold 98% and the American Rivers shareholders should hold 2% of the new company.
Although American Rivers has no substantial assets, the boards believe that
because the structure of American Rivers facilitates the change of the Alliance
shareholders' investment from the U.K. to the U.S., the shareholders of American
Rivers should receive 2% of the resulting entity.

Recommendation of the American Rivers Board of Directors

     The Board of Directors of American Rivers has unanimously approved and
recommends that all American Rivers shareholders approve the reincorporation.

     In reaching its decision, the board reviewed the fairness to American
Rivers and its shareholders of the proposed transactions and determined that,
because the transaction with Alliance will preserve some value and liquidity for
shareholders of American Rivers, which would not be preserved if American Rivers
were to liquidate, the transactions are in the best interests of the American
Rivers shareholders.  The directors noted that the principal shareholders of
American Rivers have attempted for more than the past year to identify and reach
an arrangement with a third party similar to the proposed transactions and have
not been able to conclude any other arrangement. Therefore, the Board of
Directors believes that the proposed transactions offer the American Rivers
shareholders a unique opportunity to continue their investment.

Recommendation of the Alliance Board of Directors

     The Board of Directors of Alliance has unanimously approved the Exchange
and Merger Agreement and recommends that all Alliance shareholders accept the
offer.

     The Board of Alliance considers that the success of the offer is crucial to
the future of Alliance and accordingly that the offer is in the interests of
Alliance and its shareholders taken as a whole.

     In reaching its decision, the board reviewed the fairness to Alliance and
its shareholders of the proposed transactions and determined that the
transaction is in the best interests of the Alliance shareholders.  Management
of Alliance believes that the most appropriate method of effecting the change of
its shareholders' investment is through an offer by an existing U.S. company
that has no substantial assets, such as American Rivers.

     The transactions consist of the reincorporation of American Rivers and the
offer to the Alliance shareholders.  The terms of the transactions are contained
in the Exchange and Merger Agreement dated July 22, 1999, among American Rivers,
new Alliance and Alliance.  The following discussion summarizes the terms of the
Exchange and Merger Agreement and is qualified in its entirety by reference to
the full text of the agreement, which is attached as Appendix A to this
document.

Overview

     The Reincorporation.  Under the terms of the Exchange and Merger Agreement,
when the reincorporation has been approved by the necessary votes of American
Rivers shareholders and the offer has been accepted by at least a majority of
the Alliance shareholders, a subsidiary of new Alliance will merge with American
Rivers.  The separate corporate existence of American Rivers will cease and the
subsidiary will be the surviving corporation. Each previously outstanding share
of the subsidiary's stock will remain outstanding and each previously
outstanding share of American Rivers common stock will be converted into .11
shares of new Alliance common stock. The previously outstanding shares of new
Alliance common stock will be canceled.

     The Offer.  Concurrently with the solicitation of the vote of the
shareholders of American Rivers, new Alliance is making an offer to the
shareholders of Alliance to acquire all of the outstanding shares of Alliance on
the basis of one share of new Alliance common stock for each ordinary share of
Alliance they hold.  The offer will be open for acceptance until 3:00 p.m.
(London time) on November 19, 1999.  An Alliance shareholder may revoke the
acceptance of the offer at any time prior to the expiration date of the offer.
New Alliance will not be entitled to make any revision to the offer. The offer
will lapse unless all its conditions, which are set out below, have been
satisfied or waived by 3:00 p.m. (London time) on November 19, 1999 or such
later date as new Alliance may determine. If the offer lapses, all prior
acceptances are expected to be of no effect and no additional acceptances may be
received. Settlements of acceptances will be made not later than 14 days after
November 19, 1999 or 14 days after receipt of a valid and complete form of
acceptance, whichever is later. The offer is not being made to and this document
does not constitute an offer in any jurisdiction to any person to whom it is not
lawful to make the offer in that jurisdiction. Further details concerning the
terms of the offer are contained in Appendix C to this document.

     When the reincorporation has been approved by the necessary votes of
American Rivers shareholders and the offer has been accepted by Alliance
shareholders holding more than 50% of the outstanding shares of Alliance, new
Alliance will declare the offer "unconditional."  In addition, once the offer
becomes unconditional in all respects, new Alliance intends to apply to the
London Stock Exchange to have the Alliance shares delisted, as is typical for
transactions of this type in the U.K.  In these circumstances the date on which
the cancellation of the listing on the London Stock Exchange would take effect
would be specified in the announcement that the offer is wholly unconditional,
and such date would be at least 20 clear business days following the date of
that announcement.  Management of Alliance therefore anticipates that once the
offer becomes unconditional, virtually all of the holders of the Alliance shares
will accept the offer.  Under U.K. law, when the holders of at least 90% of the
outstanding shares, which are the subject of the offer, of Alliance have
accepted the offer, new Alliance may compel the remaining Alliance shareholders
to accept the offer.

     The Result of the Reincorporation and the Offer.  As a result of the
foregoing, upon consummation of the transactions, if all of the Alliance
shareholders accept the offer, the Alliance shareholders will hold 98% of the
outstanding shares of new Alliance, and the current shareholders of American
Rivers will own 2% of the outstanding shares of new Alliance common stock. For
accounting purposes, the assets and liabilities of new Alliance and its
subsidiaries on a consolidated basis immediately after the consummation of the
transactions will be substantially identical to the assets and liabilities of
Alliance and its subsidiaries on a consolidated basis immediately prior to the
transactions.

     In addition, after the transactions new Alliance will have outstanding
warrants to purchase up to 6,272,730 shares of new Alliance common stock at
prices varying from $0.01 to $1.60 per share, options to purchase up to 275,000
shares of new Alliance common stock at a price of $10.00 per share and equity
securities convertible into up to 20,000,000 shares of common stock depending on
the production and reserves attributable to the company's U.K. interests.  See
"Security Ownership."  All of these instruments will provide the holders rights
on terms that are substantially similar to the terms of their existing
arrangements with Alliance.

                                       14

     The transactions will result in changes in the rights and obligations of
current Alliance and American Rivers shareholders under applicable corporate
laws. For an explanation of these differences, see "Comparative Rights of
Shareholders."

Conditions to the Transactions and Effective Time

     The offer and the obligation of each of the parties to the Exchange and
Merger Agreement is subject to the satisfaction of the following conditions at
or prior to the time the merger becomes effective:

     1.   The shareholders of American Rivers must have approved the
          reincorporation.

     2.   The holders of at least a majority of the ordinary shares of Alliance
          must have accepted the offer.

     3.   No action, suit or proceeding is pending or threatened in which an
          unfavorable ruling would prevent any of the transactions;  cause any
          of the transactions to be rescinded following completion; cause new
          Alliance, Alliance or American Rivers, or any of their officers or
          directors, to become liable for any material damages; or affect
          adversely the right of new Alliance to own the former assets or to
          operate the former businesses of American Rivers.

     4.   There has not been any statute, rule or regulation enacted,
          promulgated or deemed applicable to the transactions by any
          governmental entity that prevents the transactions.

     5.   New Alliance must have entered into agreements with the holders of
          Alliance's warrants, convertible loan notes and convertible restricted
          voting shares providing for issuance of warrants, convertible shares
          or common stock to those holders on substantially the same terms as
          those instruments currently provide with respect to Alliance.

     The transactions, including the offer, will become effective when these
conditions have been met, which we anticipate will be promptly after the meeting
of the American Rivers shareholders and, in any event, will not be later than
November 19, 1999 or such later date as new Alliance may determine.

Termination

     The Exchange and Merger Agreement may be terminated and the reincorporation
may be abandoned at any time before formal announcement of the offer is made, by
action of the boards of directors of both American Rivers and Alliance.


Consequences Under Federal Securities Laws; Resale of New Alliance Stock

     The new Alliance common stock issuable in connection with the transactions
have been registered under the Securities Act.  Accordingly, there will be no
restrictions upon the resale or transfer of such shares by stockholders, except
for those unitholders or stockholders who are considered "affiliates" of
American Rivers or Alliance, as that term is defined in Rule 144 and Rule 145
adopted under the Securities Act.

     New Alliance stock received by those stockholders who are considered to be
"affiliates" of American Rivers or Alliance may be resold without registration
only as provided for by Rule 145 or as otherwise permitted under the Securities
Act.  Persons who may be considered to be affiliates of American Rivers or
Alliance generally include individuals or entities that control, are controlled
by or are under common control with, American Rivers or Alliance and may include
the executive officers and directors of American Rivers and Alliance, as well as
some of the principal stockholders of American Rivers and Alliance.

Accounting Treatment

     As a result of the Alliance shareholders owning approximately 98% of the
combined company, Alliance will be treated as having acquired American Rivers
for accounting purposes.  Alliance has treated the business combination as an
issuance of securities.  Accordingly, the fair value of the tangible net assets
of American Rivers has been credited to stockholders' equity.

              VOTING INFORMATION FOR AMERICAN RIVERS SHAREHOLDERS

Special Meeting

     A special meeting of the American Rivers shareholders will be held at 10:00
a.m. on November 18, 1999, at the offices of American Rivers, 700 East Ninth
Avenue, Suite 106, Denver, Colorado 80203 (or at any adjournments or
postponements thereof) to consider and vote on the proposal to approve the
reincorporation and any other matters that may properly come before such
meeting. The presence, in person or by proxy, of shareholders holding a majority
of the outstanding shares of American Rivers common stock and Class B Common
Stock, in the aggregate, will constitute a quorum. Only those shareholders of
record at the close of business on October 12, 1999, as shown in the records of
American Rivers, will be entitled to vote or to grant proxies to vote at the
special meeting.

Record Date

     Only those shareholders of record at the close of business on October 12,
1999, as shown in the records of American Rivers, will be entitled to vote or to
grant proxies to vote at the special meeting.

Vote Required For Approval

     Approval of the reincorporation requires the affirmative vote of the
shareholders of American Rivers holding at least a majority of the outstanding
shares of American Rivers common stock and Class B Common Stock, voting as a
single class.  As of October 12, 1999, there were 3,565,770 shares of American
Rivers common stock and 7,267,820 shares of American Rivers Class B Common Stock
outstanding and entitled to vote. The directors and executive officers of
American Rivers and their affiliates directly owned, in the aggregate, 5,795,967
shares (approximately 53.5%) of the total number of shares of American Rivers
common stock and Class B Common Stock outstanding at the record date. These
persons have indicated that they will vote all of their shares of American
Rivers

                                       16

common stock and Class B Common Stock for the approval of the reincorporation.
Therefore, American Rivers is not soliciting proxies in connection with the
meeting.

Dissenters' Rights

     Shareholders of American Rivers are entitled to assert dissenters' rights
under Article 13 of the Wyoming Business Corporation Act in connection with the
reincorporation. A copy of Article 13 is included as Appendix B. The following
discussion of dissenters' rights is qualified in its entirety by reference to
the provisions of Article 13, which is hereby incorporated by reference.

     Notice of Intent to Demand Payment.  Any shareholder who wishes to assert
dissenters' rights must do both of the following:

     1. Deliver to American Rivers, before the vote on the reincorporation is
        taken at the special meeting, written notice of the shareholder's
        intention to demand payment for the shareholder's shares if the
        reincorporation is effectuated; and

     2. Not vote the shares in favor of the reincorporation.

     Any shareholder who does not satisfy these requirements is not entitled to
demand payment for the shareholder's shares under Article 13.

     Demanding Payment for Shares.  If the reincorporation is approved, American
Rivers will give a written notice to all shareholders who have satisfied the
requirements of Items 1 and 2 above and are entitled to demand payment for their
shares.  The notice will be given no later than 10 days after the Effective Date
of the reincorporation and will describe the procedures dissenting shareholders
must follow to demand payment for their shares.  The notice will also inform
dissenting shareholders of any restrictions on the transfer of their shares
after the payment demand is received by American Rivers.  Subject to very
limited exceptions, the demand for payment and deposit of share certificates are
irrevocable.

     Shareholders who do not demand payment and deposit their share certificates
in the manner required, and by the date or dates set forth in the dissenters'
notice given by American Rivers, are not entitled to payment for their shares
under Article 13.

     Payment for Shares.  Subject to certain limited exceptions, upon the later
of the Effective Date of the reincorporation or the receipt of a payment demand,
American Rivers will pay to the dissenting shareholder the amount American
Rivers estimates to be the fair value of the dissenting shareholder's shares,
plus accrued interest. The payment will be accompanied by, among other things,
financial statements of American Rivers, a statement of American Rivers'
estimate of the fair value of the shares, and an explanation of how interest was
calculated.

     Procedure if Dissatisfied with Payment Amount.  If a dissenting shareholder
believes that the amount paid or offered by American Rivers is less than the
fair value of the shares or that interest due was incorrectly calculated, the
shareholder may give written notice to American Rivers of the shareholder's
estimate of the fair value of the shares and the amount of interest due and may
demand payment of such estimate, less any payment made by American Rivers.  A
dissenting shareholder waives this right unless the shareholder causes American
Rivers to receive the notice within 30 days after American Rivers pays or offers
to pay the shareholder for the shares.

     Court Action to Resolve Payment Amount.  If any dissenting shareholder
demands payment as provided in the immediately preceding paragraph, American
Rivers may, within 60 days after receiving the payment demand, commence a
proceeding and petition a court to determine the fair value of the shares and
accrued interest.  If American Rivers does not commence the proceeding within
this 60-day period, it must pay to each dissenting shareholder whose demand
remains unresolved the amount demanded by the shareholder.

     Each dissenting shareholder who is made a party to the court action is
entitled to the amount, if any, by which the court finds the fair value of the
dissenting shareholder's shares, plus interest, exceeds the amount paid by
American Rivers.

                                       17

Exchange of Share Certificates

     At the completion of the transactions, all American Rivers shares will
cease to be outstanding and will automatically be canceled and retired.  Each
certificate formerly representing American Rivers shares, other than those held
by shareholders who have properly exercised their right to dissent, will
represent ownership of the right to receive the new Alliance common stock to
which they are entitled as a result of the reincorporation until those
certificates are surrendered to the exchange agent.  The exchange agent for the
transactions is AST.

Fractional Shares

     You will not receive any fractional shares of new Alliance common stock as
a result of the reincorporation. Instead of fractional shares, you will receive,
upon surrender of your certificate(s) to the exchange agent, along with the
signed letter of transmittal, a number of shares rounded up or down to the
nearest whole share. Half shares will be rounded up to the next whole share.

                        MATERIAL TAX CONSEQUENCES OF THE
                              MERGER AND EXCHANGE

United States Taxation

     In the opinion of Jenkens & Gilchrist, a Professional Corporation, "U.S.
Special Tax Counsel" to  American Rivers and Alliance, the following are
material United States federal tax considerations arising from and relating to
the merger (the "Merger") and the exchange (the "Exchange") of Alliance shares
for new Alliance shares that are generally applicable to you if you are a U.S.
Shareholder and in some cases if you are a non-U.S. Shareholder.  You are a U.S.
Shareholder if you are a United States citizen or resident, domestic
corporation, domestic partnership, estate subject to United States federal
income tax on your income regardless of source, or a trust but only if a court
within the United States is able to exercise primary supervision over your
administration and one or more United States fiduciaries have the authority to
control all of the substantial decisions of the trust.  Otherwise, you are a
non-U.S. Shareholder.

     This opinion does not address all of the United States federal tax
consequences that may be relevant to you in light of your particular
circumstances, including:

        . the United States federal income tax consequences to U.S. Shareholders
          who directly or indirectly own 10 percent or more, by vote or value,
          of the stock of Alliance;

        . the potential application of the alternative minimum tax; or

        . the United States federal income tax consequences to certain types of
          investors subject to special treatment under the United States federal
          income tax laws, such as life insurance companies, broker-dealers,
          financial institutions, tax-exempt entities, holders of stock who
          received such stock as compensation, certain United States nonresident
          alien individuals who were United States citizens or United States
          lawful permanent residents within the past ten years.

     The explanation of material United States federal tax laws set out below is
based on the Internal Revenue Code of 1986, as amended (the "Code"), existing
and proposed regulations, IRS rulings and pronouncements, reports of
congressional committees, judicial decisions and current administrative rulings
and practice, all as of the date of this document, and which are subject to
change.  Any such change could be retroactive and change the United States
federal tax consequences discussed below.  No advance ruling from the Internal
Revenue Service with respect to these matters has been requested.  Accordingly,
it is possible that the United States federal tax consequences of the Merger and
Exchange may differ from those described below.  No United States state or local
tax considerations are discussed.

     All American Rivers and Alliance shareholders are urged to consult their
professional tax advisors regarding the specific tax consequences of the Merger
and Exchange, including the applicability of united states federal income tax
law, state and local tax laws, the tax laws of any other jurisdiction to which
they may be subject; possible future changes in U.S. federal income tax laws;
and any pending or proposed legislation.

                                       18

     The Merger.  In the opinion of U.S. Special Tax Counsel, the following are
material United States federal income tax considerations arising from and
relating to the Merger that are applicable to American Rivers, new Alliance, the
subsidiary of new Alliance into which American Rivers will merge and you.  As
described in more detail below, the Merger should qualify as tax-free to
American Rivers, new Alliance, the subsidiary of new Alliance into which
American Rivers will merge and you provided you are a U.S. Shareholder and
exchange your shares pursuant to the Merger.  This conclusion is based on
factual assumptions and reliance on representations from American Rivers, new
Alliance and the subsidiary of new Alliance into which American Rivers will
merge.

     This discussion is based upon United States laws, regulations, rulings and
decisions currently in effect, all of which are subject to change, possibly with
retroactive effect.  No advance income tax ruling has been sought or obtained
from the Internal Revenue Service regarding the tax consequences of any of the
transactions.  Accordingly, the United States federal income tax consequences to
you, American Rivers, new Alliance and the subsidiary of new Alliance into which
American Rivers will merge of the Merger may differ from those described
below.

     Consequences of the Merger to American Rivers Shareholders.  The Merger of
American Rivers into the wholly-owned subsidiary of new Alliance should qualify
as a tax-free reorganization.  If you are a U.S. Shareholder of American Rivers
and exchange your shares pursuant to the Merger, you should not recognize any
gain or loss on the Merger for United States federal income tax purposes.  Your
basis and holding period in the shares of new Alliance common stock received in
such exchange pursuant to the Merger, should be the same as your respective
basis and holding period in the stock in American Rivers exchanged therefor in
the Merger.

     In contrast, if you are an U.S. Shareholder of American Rivers and exercise
your dissenter's rights in accordance with the standards described in the
section above entitled "Dissenters' Rights", the conclusions in the immediately
preceding paragraph concerning the tax treatment and the various consequences
thereof to American Rivers shareholders do not apply.  As a result, if you are a
U.S. Shareholder of American Rivers and the conditions contained in this
paragraph apply, you will recognize taxable gain or loss equal to the difference
between (i) the payment you receive from American Rivers calculated to be the
fair market value of your shares and (ii) your adjusted tax basis in the shares
of American Rivers common stock.  The gain or loss will generally be a capital
gain or loss provided the shares are held as a capital asset as defined in
Section 1221 of the Code.  Any capital gain or loss will be a long-term capital
gain or loss if your holding period for United States federal income tax
purposes in such shares is more than 1 year as of the date of the exchange.

     If you are a non-U.S. Shareholder and you own and have owned 5% or less of
the total fair market value of common stock of American Rivers during the 5 year
period ending on the date of the Merger, you should not be subject to United
States federal income tax or withholding tax with respect to the exchange of
your shares of American Rivers pursuant to the Merger.  If you are a non-U.S.
Shareholder who does not meet the foregoing criteria (including, but not limited
to Class B common stockholders and non-U.S. Shareholders owning more than 5% of
the total fair market value of common stock of American Rivers during the 5 year
period ending on the date of the Merger), you are urged to consult your own tax
advisors regarding your particular United States federal tax consequences.

     Consequences of the Merger to American Rivers and new Alliance.  The Merger
should qualify as tax-free to American Rivers and new Alliance with the
following United States federal income tax consequences:

        . The subsidiary of new Alliance into which American Rivers will merge
          will recognize no gain or loss on the receipt of American Rivers'
          assets;

        . American Rivers will recognize no gain or loss in connection with the
          Merger;

        . The subsidiary of new Alliance into which American Rivers will merge
          will take a tax basis in the assets of American Rivers equal to
          American Rivers' tax basis immediately prior to the Merger; and

        . The holding period in the American Rivers assets received by the
          subsidiary of new Alliance into which American Rivers will merge will
          include American Rivers' holding period in such assets.

                                       19
<PAGE>

     The Exchange.

     In the opinion of U.S. Special Tax Counsel, the following are material
United States federal income tax considerations arising from and relating to the
Exchange that are applicable to Alliance, new Alliance and you.  As described in
more detail below, the Exchange should qualify as tax-free to Alliance, new
Alliance and you provided you accept the offer and are either a non-U.S.
Shareholder or you are a U.S. Shareholder and shareholders owning at least 80
percent of the total combined voting power of all classes of stock entitled to
vote exchange their shares pursuant to the offer.  This conclusion is based on
factual assumptions and reliance on representations from Alliance and new
Alliance.

     This discussion is based upon United States laws, regulations, rulings and
decisions currently in effect, all of which are subject to change, possibly with
retroactive effect.  No advance income tax ruling has been sought or obtained
from the Internal Revenue Service regarding the tax consequences of any of the
transactions.  Accordingly, the United States federal income tax consequences to
you, Alliance and new Alliance of the Exchange may differ from those described
below.

     U.S. Shareholders.  The following discussion applies if you are a U.S.
Shareholder and



        . your ownership, receipt or disposition of ordinary shares of Alliance
          and/or New Alliance common stock is not attributable to a permanent
          establishment in a country other than the United States for purposes
          of an income tax treaty to which the United States is a party;

        . you are not a resident of a country other than the United States for
          purposes of an income tax treaty to which the United States is a
          party; and

        . you do not and have not actually or constructively owned 10 percent or
          more of the voting stock of Alliance at any time in the 5-year period
          ending immediately prior to the Exchange.

If you are a U.S. Shareholder and do not meet one or more of the foregoing
criteria, you should consult your tax advisors regarding your particular United
States federal income tax consequences.

     The Exchange --Greater than 80 Percent Acceptance.

     The United States federal income tax consequences of the Exchange of
Alliance common stock, pursuant to the offer in exchange for common stock in new
Alliance to you depends upon whether shareholders owning at least 80 percent of
total combined voting power of all classes of stock entitled to vote exchange
all of their shares pursuant to the offer.  If shareholders owning at least 80
percent of the total combined voting power of all classes of stock entitled to
vote exchange all of their shares pursuant to the offer, the Exchange should
qualify as a reorganization within the meaning of Section 368(a) of the Code
with the following United States federal income tax consequences provided you
accept the offer:

        . You will not recognize gain or loss from the Exchange;

        . The United States federal income tax basis of the new Alliance common
          stock you receive pursuant to the Exchange will be the same as the tax
          basis of the ordinary shares of Alliance you surrender in exchange
          therefor; and

        . The holding period for the shares of new Alliance common stock
          acquired in the Exchange will include the holding period of the
          ordinary shares of Alliance surrendered in exchange therefor.

     If you do not accept the offer, and shareholders owning at least 90 percent
of the value of the ordinary shares of Alliance do not exchange all of their
shares pursuant to the offer, your nonacceptance of the offer will not have any
United States federal income tax consequences to you.  In contrast, if you do
not accept the offer and shareholders owning at least 90 percent of the value of
the ordinary shares of Alliance exchange all of their shares pursuant to the
offer, your shares in Alliance will be exchanged for shares in new Alliance and
you will be subject to the United States federal income tax consequences
discussed in this section as if you had accepted the offer.

     Internal Revenue Service Notice Requirement

     If you receive common stock of new Alliance in the Exchange and take the
position that such Exchange is eligible for tax-free nonrecognition treatment,
you are required to file a notice with the Internal Revenue Service on or before
the last day for filing a United States federal income tax return (taking into
account any extensions of time therefor) for your taxable year in which the
Exchange occurs if you would have realized a gain had the Exchange been taxable.
The notice must contain the information specifically enumerated in Section
7.367(b)-1 of the United States Treasury Regulations, and you are advised to
consult your tax advisors for assistance in preparing that notice.  If you are
required to give notice as described and do not, and if you fail to establish
reasonable cause for the failure, the Internal Revenue Service will be required
to determine, based on all of the facts and circumstances, whether the Exchange
is eligible for nonrecognition treatment.  In making the determination, the
Internal Revenue Service may conclude:

        . that the Exchange is eligible for nonrecognition treatment, despite
          any noncompliance;

        . that the Exchange is eligible for nonrecognition treatment, provided
          that certain other conditions imposed by the United States Treasury
          Regulations are satisfied; or

        . that the Exchange is not eligible for nonrecognition treatment and
          that any gain recognized will be taken into account for purposes of
          increasing the tax basis of your shares of common stock in new
          Alliance received in the Exchange.

Nevertheless, the failure of another U.S. Shareholder to satisfy the foregoing
notice requirements should not bar you from receiving nonrecognition treatment
with respect to the Exchange if you satisfy the requirements listed above.

     The Exchange --Less than 80 Percent Acceptance.

     If shareholders owning at least 80 percent of the total combined voting
power of all classes of stock entitled to vote do not exchange all of their
shares pursuant to the offer, the Exchange should not qualify as a tax-free
reorganization within the meaning of Section 368(a) of the Code.  If the
Exchange does not qualify as reorganization, the conclusions in the immediately
preceding paragraphs concerning tax treatment and the various consequences
thereof do not apply.  As a result, if you are a U.S. Shareholder and you
exchange your shares under those  circumstances, you will recognize taxable gain
or loss equal to the difference between (i) the sum of the fair market value of
the new Alliance common stock received in the Exchange on the date of the
Exchange and (ii) your adjusted tax basis in the ordinary shares of Alliance you
exchanged on the date of the Exchange.  The gain or loss will generally be a
capital gain or loss provided the shares are held as a capital asset as defined
in Section 1221 of the Code.  Any capital gain or loss will be a long-term
capital gain or loss if your holding period for United States federal income tax
purposes in such shares is more than 1 year as of the date of the Exchange.

     Passive Foreign Investment Company Considerations.  For United States
federal income tax purposes, Alliance generally will be classified as a passive
foreign investment company as defined in Section 1297 of the Code ("PFIC") for
any taxable year during which either:

     .  75 percent or more of its gross income is passive income, as defined for
        United States federal income tax purposes; or

     .  on average for such taxable year, 50 percent or more of its assets by
        value produce or are held for the production of passive income.

     For purposes of applying these tests, all or some of the assets and gross
income of Alliance's subsidiaries will be attributed to it. While there can be
no assurance with respect to the classification of Alliance as a PFIC, Alliance
believes that it was not a PFIC during any taxable year ending at or prior to
consummation of the Exchange. In connection with the transaction contemplated in
this document, U.S. Special Tax Counsel will not be rendering an opinion with
regard to the Alliance's status as a PFIC. In addition, Alliance has not asked,
nor does it intend to ask, for a ruling from the Internal Revenue Service
addressing whether Alliance has been a PFIC during any taxable year ending at or
prior to the consummation of the Exchange. There is always the risk that the
Internal Revenue Service could determine that Alliance has been a PFIC and that
you may be subject to the PFIC rules set forth below. Because the United States
federal income

                                       21
<PAGE>


tax consequences to you under the PFIC provisions may be significant, you are
urged to discuss those consequences with your tax advisors.

     Non-U.S. Shareholders.  The following discussion applies to you if you are
a non-U.S. Shareholder and

        . you hold ordinary shares of Alliance or will hold shares of common
          stock in new Alliance as capital assets within the meaning of Section
          1221 of the Code;

        . you do not actually or constructively own, nor have you at any time in
          the preceding five-year period actually or constructively owned, five
          percent or more of the stock of Alliance;

        . your ownership, receipt or disposition of ordinary shares in Alliance
          and/or common stock in new Alliance is not attributable either to the
          conduct of a trade or business in the United States or to a permanent
          establishment in the United States;

        . you are not a resident of the United States for purposes of United
          States federal income tax law or an income tax treaty to which the
          United States is a party; and

        . you are not subject to tax pursuant to the provisions of the Code
          applicable to some United States expatriates.

If you are a non-U.S. Shareholder who does not meet one or more of the foregoing
criteria, you are urged to consult your own tax advisors regarding your
particular United States federal tax consequences.

     The Exchange.  Whether or not the Exchange qualifies as a tax-free
reorganization within the meaning of Section 368(a) of the Code, you will not
generally be subject to United States federal income tax on gain recognized, if
any, upon the Exchange unless:

     .  the gain is effectively connected with the conduct of a trade or
        business within the United States by you;

     .  the gain is attributable to a permanent establishment in the United
        States;

     .  you are a nonresident alien and hold shares of Alliance common stock as
        a capital asset, you are present in the United States for 183 or more
        days in the taxable year and certain other circumstances are present; or

     .  you are subject to tax pursuant to the provisions of the Code applicable
        to some United States expatriates.

If you would be subject to United States federal income tax on such gains and
take the position that the exchange of shares of common stock in Alliance for
shares of common stock in new Alliance is eligible for nonrecognition treatment,
you will be required to file a notice with the Internal Revenue Service.  See
"U.S. Shareholders- Internal Revenue Service Notice Requirement" above.

     Dividends on new Alliance Common Stock.  Generally, dividends received by
you with respect to new Alliance common stock will be subject to United States
withholding tax at a rate of 30 percent, which rate may be subject to reduction
by an applicable income tax treaty.  For example, the withholding rate is
generally 15 percent on dividends paid to residents of the United Kingdom who
qualify for the benefits of the income tax treaty between the United States and
the United Kingdom which is reduced to 5 percent on dividends paid to corporate
residents of the United Kingdom who control, directly or indirectly at least 10
percent of the voting stock of the payor and who qualify for the benefits of the
income tax treaty between the United States and the United Kingdom.  If the
dividends you receive are effectively connected with the conduct of a United
States trade or business or are attributable to a permanent establishment in the
United States of yours, they will be taxed at the graduated rates that are
applicable to United States citizens, resident aliens and domestic corporations
and will not be subject to United States withholding tax if you give an
appropriate statement to the withholding agent in advance of the dividend
payment.  A non-U.S. Shareholder that is a corporation may be subject to an
additional branch profits tax on effectively connected dividends, with certain
adjustments.

     Sale of new Alliance Common Stock.  You will generally not be subject to
United States federal income tax on gain recognized, if any, upon the sale of
shares of new Alliance common stock unless:

     .  the gain is effectively connected with conduct of a trade or business
        within the United States;

     .  the gain is attributable to a permanent establishment in the United
        States;

     .  you are a nonresident alien individual and hold the new Alliance common
        stock as a capital asset, you are present in the United States for 183
        or more days in the taxable year and other specific circumstances are
        present;

     .  you are subject to tax pursuant to the provisions of the Code applicable
        to certain United States expatriates;

     .  New Alliance is or has been a "United States real property holding
        corporation" ("USRPHC") for United States federal income tax purposes,
        as such term is defined by Section 897(c) of the Code, and you owned
        directly or pursuant to attribution rules at any time during the five
        year period ending on the date of the disposition more than 5 percent of
        the value or vote of new Alliance common stock; or

     .  New Alliance ceases to be regularly traded on an established securities
        market, within the meaning of Section 897(c)(3) of the Code prior to the
        sale.

Alliance believes that the as of the date of the Exchange, new Alliance will not
be a USRPHC and that new Alliance common stock will be treated as being traded
on an established exchange.

     Estate Tax.  New Alliance common stock owned, or treated as owned, by an
individual who is a non-U.S. Shareholder may be included in his or her gross
estate for United States federal estate tax purposes and thus may be subject to
United States federal estate tax, unless an applicable estate tax treaty
provides otherwise.

     Information Reporting and Backup Withholding.  New Alliance must report
annually to the Internal Revenue Service and to you and all other shareholders
the amount of dividends paid that year, and the tax withheld with respect to
such dividends, if any.  These information reporting requirements apply
regardless of whether withholding tax was reduced by an applicable income tax
treaty.  Copies of these information returns reporting such dividends and
withholding are generally made available to the tax authorities in the country
in which a non-U.S. Shareholder resides under the provisions of an applicable
income tax treaty or other agreement with the tax authorities in that country.

     In general, information reporting requirements may apply to dividend
distributions on new Alliance common stock, or the proceeds of a sale or
exchange of new Alliance common stock.  A 31 percent backup withholding tax may
apply to these payments unless the payment comes within a specific exempt
category or you are a corporation or come within a specific exempt category and,
when required, demonstrate your exempt status or provide a correct taxpayer
identification number, certify as to no loss of exemption from backup
withholding and otherwise comply with applicable requirements of the backup
withholding rules.  If you are required to provide your correct taxpayer
identification number and fail to do so, you may be subject to penalties imposed
by the Internal Revenue Service.

     United States backup withholding tax generally will not apply to dividends
paid on new Alliance common stock that are subject to the 30 percent or reduced
treaty rate of withholding previously discussed  or on which withholding is not
otherwise required pursuant to section 1.1441-4(a) and (f) of the United States
Treasury Regulations, provided any documentation necessary to establish your
status is properly furnished.  Under current law, dividends paid on new Alliance
common stock to you at an address outside the United States are generally exempt
from backup withholding tax, but not from 30% withholding rate, as discussed
above.

      On October 14, 1997 the Internal Revenue Service issued final regulations
which affect your United States taxation.  Under the these regulations, for
dividends paid after December 31, 2000, a non-United States person must
generally provide proper documentation indicating their status to a withholding
agent in order to avoid backup withholding tax.  However, dividends paid to
exempt recipients, not including individuals, will not be subject to backup
withholding even if such documentation is not provided if the withholding agent
is allowed to rely on certain presumptions concerning the recipient's non-United
States status (i.e. payment to an address outside the United States).

<PAGE>

     If you are a non-U.S. Shareholder, payments of proceeds from the sale of
shares of common stock in New Alliance by you made to or through a non-United
States office of a broker generally will not be subject to information reporting
or backup withholding.  However, payments made to or through a non-United States
office of a United States broker or a non-United States office of a non-United
States broker that has certain specified connections with the United States, are
generally subject to information reporting, but not backup withholding unless
you certify your non-United States status under penalties of perjury or
otherwise establish your entitlement to an exemption.  Payments of proceeds from
the sale of new Alliance common stock by you made to or through a United States
office of a broker are generally subject to both information reporting and
backup withholding at a rate of 31 percent unless you certify your non-United
States status under penalties of perjury or otherwise establish your entitlement
to an exemption.

     Any amounts withheld under the backup withholding rules from a payment to
you will be allowed as a credit against your United States federal income tax,
provided that the required information is furnished to the Internal Revenue
Service.

United Kingdom Taxation

     In the opinion of Hobson Audley Hopkins & Wood, "U.K. Tax Advisors" to
Alliance, the following are material U.K. tax considerations arising from and
relating to the offer.

                                       24
<PAGE>


     United Kingdom Resident Shareholders. The following paragraphs, which are
intended as a general guide only, are based on current U.K. legislation and
Inland Revenue practice. They summarize certain limited aspects of the U.K. tax
treatment of acceptance of the offer, and they relate only to the position of
validly accepting shareholders who hold their Alliance shares as an investment
and who are resident or ordinarily resident in the U.K. for taxation purposes
and who are not resident in any other territory. If you are subject to taxation
in any other jurisdiction, or are in any doubt as to your taxation position you
should consult an appropriate adviser without delay.

     Taxation of Capital Gains

     (a)  A holder of ordinary shares of Alliance who, either alone or together
with persons connected with him, does not hold more than 5% of the ordinary
shares of Alliance will not be treated as making a disposal for the purposes of
United Kingdom capital gains tax as a consequence of receiving new Alliance
common stock in exchange for his ordinary shares of Alliance.  Any gain or loss
which would otherwise have arisen on a disposal by such holder of his ordinary
shares of Alliance will be "rolled over" into his new Alliance common stock.
The new Alliance common stock will be treated as the same asset as his ordinary
shares of Alliance acquired at the same time and for the same consideration as
he acquired his ordinary shares of Alliance.

     (b)  A holder of ordinary shares in Alliance who, either by himself or with
other persons connected with him, holds more than 5% thereof may or may not also
be treated as one holding 5% or less.

     (c)  A subsequent disposal of New Alliance common stock received in
exchange for ordinary shares of Alliance may, depending on individual
circumstances, give rise to a liability to United Kingdom taxation of capital
gains.

     (d)  A U.K. resident who is domiciled within the U.K. and is a participator
in a non-U.K. resident company which would be "close" if it were U.K. resident
and which holds ordinary shares of Alliance will have attributed to him a
proportion of any gain realized by the company as a consequence of receiving new
Alliance common stock in exchange for ordinary shares of Alliance, unless his
share of such gain does not exceed 5% thereof.

     (e)  A U.K. resident settlor or U.K. resident and domiciled beneficiary of
a trust which is not resident in the U.K. for capital gains tax purposes and
holds ordinary shares of Alliance or is a participator in a non-resident company
which would be close if it were resident in the U.K. and which holds ordinary
shares of Alliance may in certain circumstances be chargeable on any gain
realized as a consequence of the trust or company receiving new Alliance common
stock in exchange for ordinary shares of Alliance or, except in the case of a
settlor who is not domiciled in the U.K., where any gain is "rolled over" into
new Alliance common stock, on disposal of that common stock.

     Stamp duty and Stamp Duty Reserve Tax

     No stamp duty or stamp duty reserve tax will be payable by validly
accepting shareholders as a result of accepting the offer.

     Other Taxation Matters

     Special provisions may apply to Alliance shareholders who have acquired or
acquire their ordinary shares of Alliance by exercising options under any share
schemes, including provisions imposing a charge to income tax.

     Shareholders neither resident nor ordinarily resident in the United
Kingdom.  The following paragraphs, which are intended as a general guide only,
are based on current U.K. legislation and Inland Revenue practice.  They relate
only to the position of validly accepting shareholders who hold their ordinary
shares of Alliance as an investment and who are neither resident nor ordinarily
resident in the U.K. for taxation purposes.  However, if you are in any doubt as
to your taxation position you should consult an appropriate adviser without
delay.

     Taxation of capital gains

     No capital gains tax will be payable by validly accepting shareholders as a
result of accepting the offer unless, in certain circumstances, the accepting
shareholder is an individual or an individual is a participator, settlor or
beneficiary who would be affected by paragraphs (d) or (e) above if resident,
and he resumes U.K. residence after an interval including fewer than five years
ending 5 April during which he was not resident in the United Kingdom.

                                       25

     Stamp duty and stamp duty reserve tax

     No stamp duty or stamp duty reserve tax will be payable by validly
accepting shareholders as a result of accepting the offer.

     Other taxation matters

     Special provisions may apply to Alliance shareholders who have acquired or
acquire their ordinary shares of Alliance by exercising options under any share
schemes, including provisions imposing a charge to income tax.

     Shareholders with Dual Residence.  Holders of Alliance ordinary shares who
are resident in both the United Kingdom and another territory should consult an
appropriate adviser to ascertain which jurisdiction has taxing rights over any
gain realized as a consequence of receiving new Alliance common stock in
exchange for ordinary shares of Alliance or, where any gain is "rolled over"
into new Alliance common stock, on disposal of that common stock.

     Stamp duty and stamp duty reserve tax

     No stamp duty or stamp duty reserve tax will be payable by validly
accepting shareholders as a result of accepting the offer.

     Other taxation matters

     Special provisions may apply to Alliance shareholders who have acquired or
acquire their ordinary shares of Alliance by exercising options under any share
schemes, including provisions imposing a charge to income tax.


                      COMPARATIVE RIGHTS OF SHAREHOLDERS

     When the transactions are completed, the former shareholders of Alliance,
which is a U.K. public limited company, and American Rivers, a Wyoming company,
will become shareholders of new Alliance, a Delaware company. Differences
between U.K., Wyoming and Delaware law will result in various changes in the
rights of shareholders of Alliance and American Rivers.

     The following is a summary of the rights of the shareholders of Alliance
and American Rivers compared to those of new Alliance shareholders under
applicable law and charter documents. This summary does not purport to be
complete and is qualified in its entirety by reference to new Alliance's
Certificate of Incorporation and Bylaws, which are exhibits to the registration
statement of which this document is a part.

                   ANTI-TAKEOVER PROVISIONS OF DELAWARE LAW
              AND OF THE ORGANIZATIONAL DOCUMENTS OF NEW ALLIANCE

     The new Alliance certificate of incorporation and new Alliance bylaws
contain a number of provisions that may inhibit or impede the acquisition or
attempted acquisition of control of new Alliance by means of a tender offer,
proxy contest or otherwise. These provisions are expected to discourage coercive
takeover practices and inadequate takeover bids and to encourage persons seeking
to acquire control of new Alliance to negotiate first with the new Alliance
board. These provisions may increase the likelihood that proposals initially
will be on more attractive terms than would be the case in their absence and
increase the likelihood of negotiations. This might outweigh the potential
disadvantages of discouraging these proposals because, among other things,
negotiation of the proposals might result in an improvement of their terms. The
discussion below highlights some of these anti-takeover provisions in the new
Alliance charter documents. Because it is a summary, it may not contain all of
the information that might be important to you. We urge you to read the new
Alliance certificate of incorporation and the new Alliance bylaws, copies of
which have been filed as exhibits to the registration statement of which this
document is a part, as well as the Delaware General Corporation Law for a
complete description of these anti-takeover provisions.

                                       36
<PAGE>

Classified Board Of Directors

     The new Alliance certificate of incorporation provides for a classified or
"staggered" board of directors. This means that all of the directors' terms of
office do not expire at the same time. Once the new Alliance board consists of
three or more directors, the new Alliance board will be divided into three
classes of directors, with each class constituting approximately one-third of
the total number of directors, and with the classes serving staggered three-year
terms. The classification of the new Alliance board will have the effect of
making it more difficult for stockholders to change the composition of the new
Alliance board and therefore the control of new Alliance, because only a
minority of the directors are up for election at any one time, and may be
replaced by a vote of the stockholders.

     The classification provisions also could have the effect of discouraging a
third party from accumulating a large block of the capital stock of new Alliance
or attempting to obtain control of new Alliance, even though such an attempt
might be beneficial to new Alliance and some, or a majority, of new Alliance's
stockholders. Accordingly, under some circumstances stockholders could be
deprived of opportunities to sell their new Alliance common stock and new
Alliance preferred stock at a higher price than might otherwise be available.

Number of Directors; Removal; Filling Vacancies

     After giving preference to any rights of holders of preferred shares of new
Alliance to elect additional directors under specified circumstances, the new
Alliance certificate of incorporation and the new Alliance bylaws provide that
the number of directors must not be less than one nor more than fifteen. In
addition, the new Alliance certificate of incorporation provides that, after
giving preference to rights of holders of preferred shares, any vacancies will
be filled by majority of the remaining directors, even though less than a
quorum, or by a sole director and any vacancies created by an increase in the
total number of directors may be filled only by the new Alliance board.
Accordingly, the new Alliance board could temporarily prevent any stockholder
from enlarging the new Alliance board and then filling the new positions with
the stockholder's own nominees.

     The new Alliance certificate of incorporation and the new Alliance bylaws
provide that, after giving preference to any rights of holders of preferred
shares, directors may be removed only for cause upon the affirmative vote of
holders of a majority of the entire voting power of all the then-outstanding
shares entitled to vote in the election of directors, voting together as a
single class.

Advance Notice Provisions for Director Nominations and Stockholder Proposals

     The new Alliance certificate of incorporation provides for an advance
notice procedure for stockholders to make nominations of candidates for director
or to bring other business before the annual meeting of stockholders. According
to this procedure (1) only persons who are nominated by, or at the direction of,
the new Alliance board, or by a stockholder who has given timely written notice
containing specified information to the Secretary of new Alliance prior to the
meeting at which directors are to be elected, will be eligible to nominate
candidates for director of new Alliance and (2) at an annual meeting, only such
business may be conducted as has been brought before the meeting by, or at the
direction of the new Alliance board or by a stockholder who has given timely
written notice to the Secretary of new Alliance of his intention to bring the
business before the meeting. In general, for notice of stockholder nominations
or proposed business to be conducted at an annual meeting to be timely, the
notice must be received by new Alliance not less than 60 days nor more than 90
days prior to the scheduled date of the meeting.

     The purpose of requiring stockholders to give advance notice of nominations
and other business is to afford the new Alliance board a meaningful opportunity
to consider the qualifications of the proposed nominees or the advisability of
the other proposed business. To the extent necessary or considered desirable by
the new Alliance board, the advance notice provision will allow the new Alliance
board to inform stockholders and make recommendations about the nominees or
business, as well as to ensure an orderly procedure for conducting meetings of
stockholders. Although the new Alliance certificate of incorporation does not
give the new Alliance board power to block stockholder nominations for the
election of directors or proposals for action, the advance notice procedure may
have the effect of discouraging a stockholder from proposing nominees or
business, precluding a contest for the election of directors or the
consideration of stockholder proposals if procedural requirements are not met.
This might also deter third parties from soliciting proxies for a non-management
proposal or slate of directors, without regard to the merits of the proposal or
slate.

                                       37
<PAGE>

     Any action required or permitted to be taken by the new Alliance
stockholders must be taken at a properly called annual or special meeting of the
new Alliance stockholders and may not be taken by written consent. Special
meetings of the new Alliance stockholders may be called at any time but only by
the Chairman of the board or by a majority of the directors then in office.

Preferred Shares

     The new Alliance certificate of incorporation authorizes the new Alliance
board to establish one or more series of preferred shares, and to determine
preferences, rights and other terms of those series. The purpose of allowing the
new Alliance board to issue one or more series of preferred shares is to provide
increased flexibility in structuring possible future financings and
acquisitions, and in meeting other corporate needs. The authorized preferred
shares are available for issuance without further action by the new Alliance
stockholders, unless the action is required by applicable law or the rules of
any stock exchange or automated quotation system on which the new Alliance
securities may be listed or traded. New Alliance has no present intention to,
although it could in the future, issue a series of preferred shares. A new
series of preferred stock, due to its terms, could impede a merger, tender offer
or other transaction that some, or a majority, of its stockholders might believe
to be in their best interests or in which stockholders might receive a premium
over then prevailing market prices for their new Alliance common stock.

Amendment of the new Alliance Certificate of Incorporation

     The new Alliance certificate of incorporation provides that it may be
amended only if the holders of not less than a majority of the votes entitled to
be cast vote in favor of the amendment.

Business Combinations Under Delaware Law

     New Alliance will be required to comply with the provisions of Section 203
of the Delaware General Corporation Law, a statutory provision restricting
business combinations with a category of stockholders called "interested
stockholders," defined as persons who beneficially own or acquire 15% or more of
a Delaware corporation's voting stock, with the exception of any person who
owned and has continued to own shares in excess of the 15% limitation since
December 23, 1987. Section 203 defines "business combination" broadly to include
mergers, consolidations, sales or other disposition of assets having a total
value in excess of 10% of the consolidated assets of the corporation, and other
transactions that would increase an interested stockholder's proportionate share
ownership in the corporation. Section 203 prohibits business combinations
between a publicly held Delaware corporation and any interested stockholder for
a period of three years after the date on which the interested stockholder
became an interested stockholder, unless (a) prior to that date, the
corporation's board approved either the proposed business combination or the
transaction that resulted in the interested stockholder becoming an interested
stockholder; (b) when the transaction that resulted in the interested
stockholder becoming an interested stockholder was completed, the interested
stockholder already owned at least 85% of the voting stock of the corporation
outstanding at the time; or (c) on the date on which the business combination is
approved by the corporation's board of directors and authorized at an annual or
special meeting of stockholders, the transaction was approved by at least two-

Rivers are located at 700 East Ninth Avenue, Suite 106, Denver, Colorado 80203.

     Additional information concerning American Rivers, including its business,

this document.

                             BUSINESS OF ALLIANCE

     Alliance is a United Kingdom public limited company whose principal
activities are the acquisition, exploration, development and production of oil
and gas properties. The Company currently owns producing oil and gas properties
in

                                       38

the East Irish Sea off the West coast of the U.K. and in the United States, with
a majority of its proved U.S. reserves located in the states of Alabama,
Louisiana, Mississippi, Oklahoma and Texas. Since 1996, the Company has focused
its efforts on maximizing the value of its properties in the U.S. and on
acquiring and developing suitable international opportunities. The executive
offices of Alliance are at 4200 East Skelly Drive, Suite 1000, Tulsa, Oklahoma
74135.

     In connection with its acquisition of its U.K. interests in 1998, Alliance
issued to the sellers of the U.K. interests restricted voting shares convertible
into 10,000,000 ordinary shares and a contingent right to acquire up to
10,000,000 additional ordinary shares over the next five years. It is a
condition to the offer that new Alliance enter into satisfactory agreements with
the sellers of the U.K. interests to provide the sellers with comparable rights.
Accordingly, new Alliance and the sellers of the U.K. interests have entered
into an agreement providing that new Alliance will issue to the sellers
10,000,000 convertible restricted voting shares which may be converted into up
to 20,000,000 shares of new Alliance's common stock. The number of shares of
common stock that would be actually issued as a result of this contingent right
will depend on the sales production actually achieved from, or the estimated
value attributable to, the U.K. interests, as set out in the table below. The
sellers would receive 5,000,000 shares if none of the production targets or
reserve values are achieved, 20,000,000 shares if all the production targets or
reserve values are achieved and will receive a number of shares within this
range if only some of the production targets or reserve valuations are achieved.
The convertible restricted voting shares are entitled to one-half vote per share
and to vote with the common stock on all matters. In addition, the holders of
the convertible restricted voting shares may elect one director to new
Alliance's board of directors, who will then be subject to reelection in the
same manner as other directors.

     If any Sustained Production Level (as defined below) is achieved, the
sellers will be entitled to receive the number of shares set forth below
corresponding to such Sustained Production Level. "Sustained Production Level"
means sales of production attributable to the U.K. interests for a period of at
least 90 consecutive days at rates equal to or in excess of the levels described
in the table set out below.

     If the first three Sustained Production Levels set out below are achieved,
but the fourth or fifth Sustained Production Levels set out below are not
achieved, and the Reserves Value (as defined below) is equal to or in excess of
that set out below with respect to such Sustained Production Level which has not
been achieved, then additional shares shall be issued to the sellers so that the
total number of additional shares issued to the sellers is equal to the amount
which would have been issued had the Sustained Production Level been achieved
which corresponds to such Reserves Value. "Reserves Value" means the net present
value of the following reserves, bearing interest or discounted at the rate of
10%, as applicable, net of U.K. corporate tax, and determined in accordance with
generally accepted reservoir engineering standards: (i) the proceeds previously
received which are attributable to the total volume of reserves produced and
sold from the U.K. interests from and after January 1, 1998, less the aggregate
amount of all capital expenditures and operating costs incurred since January 1,
1998 which are attributable to the U.K. interests and (ii) the proceeds
estimated to be received attributable to the total volume of hydrocarbon
reserves that geological and engineering data demonstrate, with a greater than
50% certainty, as determined by statistical means, to be recoverable from the
U.K. interests in the future from known reservoirs under existing operating
conditions based upon the most recent reserve report prepared by Alliance's
third-party engineering firm, which report shall be prepared no less often than
annually, less the aggregate amount of all capital expenditures and operating
costs attributable to such reserves.

(1)  These Reserves Values are not comparable to Pre-tax PV10 value or the
     Standardized Measure of the reserves attributable to the company's
     properties or to the U.K. interests described in other filings by Alliance
     because the calculation of "Reserves Value" is to be made in the manner
     described in the paragraph preceding this table, which is different than
     the manner in which the Pre-tax PV10 value and the Standardized Measure are
     calculated.

         SELECTED HISTORICAL CONSOLIDATED FINANCIAL AND OPERATING DATA
                              OF AMERICAN RIVERS

     The selected historical financial information for American Rivers for the
year ended March 31, 1995 includes the results of operations of properties
contributed by Karlton Terry Oil Company (KTOC) in exchange for 80% of the
outstanding voting shares of American Rivers. The exchange, for accounting
purposes, was treated as if the owners of KTOC had acquired American Rivers.
Information for periods prior to December 8, 1995 (the effective date of the
exchange) includes the results of operations of the properties contributed by
KTOC. The selected historical financial information as of and for the years
ended March 31, 1999 should be read in conjunction with American Rivers' audited
financial statements and the notes thereto included under Item 8 and
Management's Discussion of Financial Condition and Results of Operations at Item
7 contained in the American Rivers Annual Report on Form 10-KSB. The selected
historical financial information for the three months ended June 30, 1998 and
1999 is unaudited and should be read in conjunction with the unaudited financial
statements contained in the American Rivers Form 10-Q included with this
document; however, in the opinion of management, all adjustments which are of a
normal recurring nature, necessary for a fair presentation of the results of
such periods, have been made. The results of operations for the three months
ended June 30, 1998 and 1999 are not necessarily indicative of the results to be
expected for the entire fiscal year or any other interim period.

   SELECTED HISTORICAL CONSOLIDATED FINANCIAL AND OPERATING DATA OF ALLIANCE

     Alliance completed its acquisition of LaTex Resources, Inc. (LaTex) on May
1, 1997.  As the former LaTex shareholders had a controlling interest in the
combined group for accounting and financial reporting purposes, LaTex is treated
as having acquired Alliance.  The historical financial information for all
financial periods to April 30, 1997 reflect the results of operations and assets
and liabilities of LaTex.  LaTex's fiscal year end was July 31, whereas that of
Alliance is April 30.  On October 30, 1998, Alliance completed its acquisition
of Difco Limited ("Difco") and, indirectly, a contract to acquire an interest in
the East Irish Sea Properties.  The results of operations and assets and
liabilities of Difco have been included since the date of acquisition.

     The selected financial information as of and for the years ended July 31,
1995 and 1996, as of and for the nine months ended April 30, 1997, and as of and
for the years ended April 30, 1998 and 1999, should be read in conjunction with
Alliance's audited financial statements and the notes thereto included under
Item 8 and Management's Discussion and Analysis of Financial Condition and
Results of Operations at Item 7 contained in the Alliance Annual Report on Form
10-K.  The selected historical financial information for the three months ended
July 31, 1998 and 1999 is unaudited and should be read in conjunction with the
unaudited financial statements contained in the Alliance Resources Form 10-Q
included with this document; however, in the opinion of management, all
adjustments which are of a normal recurring nature, necessary for a fair
presentation of the results of such periods, have been made.  The results of
operations for the three months ended July 31, 1998 and 1999 are not necessarily
indicative of the results to be expected for the entire fiscal year or any other
interim period.

1)    During the year ended July 31, 1996, the Company ceased its overseas
      exploration activities in both Tunisia and Kazakhstan and wrote off its
      costs relating to these activities of $3,447.

2)    On May 15, 1997, the existing commodity price hedging agreements were
      terminated through a buyout. On October 23, 1997, new commodity price
      hedging agreements were initiated. The loss relating to the buy-out,
      $1,128, has been recognized in its entirety in the year ended April 30,
      1998.

3)    The miscellaneous expenses in the year ended July 31, 1996 arose from
      litigation in connection with the sale in July 1993 of a sale of a
      subsidiary of the Company.

4)    For periods ending on or before April 30, 1997, the weighted average
      number of shares outstanding has been based on the number of Alliance
      shares issued on May 1, 1997, which represent the number of LaTex shares
      outstanding in each of the relevant periods based on the exchange ratio in
      the acquisition of LaTex. The loss for each period is stated after
      deducting dividends on the LaTex preferred stock.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

     The following unaudited pro forma financial statements give effect to the
business combination contemplated by the transactions described elsewhere in
this document. The unaudited pro forma condensed balance sheet as of July 31,
1999 is presented as if the combination had occurred on that date. The unaudited
pro forma condensed statement of operations for the year ended April 30, 1999
and the three months ended July 31, 1999 assume that the business combination
occurred at the beginning of the earliest period presented.

     As a result of the Alliance shareholders owning approximately 98% of the
combined company, Alliance will be treated as having acquired American Rivers
for accounting purposes. As American Rivers has no substantial operations,
Alliance has treated the business combination as an issuance of securities.

     The unaudited pro forma combined condensed financial statements should be
read in conjunction with the historical financial statements of American Rivers
and Alliance included elsewhere in this document and "Management's Discussion
and Analysis of Financial Condition and Results of Operations" of American
Rivers and "Management's Discussion and Analysis of Financial Condition and
Results of Operations" of Alliance included elsewhere in this document. The
unaudited pro forma combined condensed statement of operations is not
necessarily indicative of the financial results that would have occurred had the
business combination been consummated on the indicated dates, nor are they
necessarily indicative of future results. The results of operations for the
three months ended July 31, 1999 are not necessarily indicative of the results
to be expected for the entire fiscal year or any other interim period.

     The pro forma adjustments are based on preliminary assumptions and
estimates made by Alliance's management. The actual allocation of the
consideration paid may differ from that reflected in the unaudited pro forma
combined condensed financial statements after a more extensive review of the
fair market values of the assets acquired and liabilities assumed has been
completed. Amounts allocated will be based upon the estimated fair values at the
effective date of the business combination, which could vary from the amounts as
of July 31, 1999; however, Alliance does not expect any differences to be
material.

                             SHAREHOLDER PROPOSALS

     If the transactions are not completed, stockholders of American Rivers may
submit proposals on matters appropriate for action at annual meetings in
accordance with regulations adopted by the SEC. However, the rules of the SEC
provide that, if an annual meeting is changed by more than 30 calendar days from
that contemplated at the time of the prior annual meeting, the proposal must be
received by the company within a reasonable time before the proxy solicitation
is made. Proposals should be directed to the attention of the Secretary of
American Rivers.

     New Alliance's Certificate of Incorporation establishes an advance notice
procedure that stockholders must follow in order to nominate directors or to
bring other business before an annual meeting of stockholders without complying
with Rule 14a-8 of the Securities Exchange Act of 1934. These advance notice
procedures require that, among other things, notice of a director nomination or
other business must be submitted in writing to the Secretary of new Alliance not
less than 60 days nor more than 90 days prior to the anniversary of the date on
which new Alliance first mailed its proxy materials for the prior annual
meeting, but if less than 70 days' notice or prior public disclosure of the date
of the meeting is given or made to stockholders, then the notice by the
stockholder must be delivered or received not later than the close of business
on the 10th day following the earlier of (i) the day on which such notice of the
date of the meeting was mailed or (ii) the day on which the public disclosure
was made.

     The notice must contain the information specified in the Certificate of
Incorporation concerning the matters to be brought before such meeting and
concerning the stockholder proposing such matters, including the name, address,
number of shares beneficially owned and any material interest of the stockholder
making the proposal. Notice of a director nomination must include information on
various matters regarding the nominee, including the nominee's name, age,
business and residence address, principal occupation and security holdings.
Notice of other business must include a description of the proposed business,
the reasons therefor and other specified matters. A copy of the relevant
provisions of new Alliance's Certificate of Incorporation may be obtained by a
stockholder without charge upon written request to the Secretary of new
Alliance. All notices of proposals by stockholders, whether or not to be
included in new Alliance's proxy materials, must be sent to AROC Inc., 4200 E.
Skelly Drive, Suite 1000, Tulsa, Oklahoma 74135, attention: Secretary.

     Any stockholder proposal must also comply with all other applicable
provisions of new Alliance's Certificate of Incorporation and Bylaws, the
Securities Exchange Act, including the rules and regulations thereunder, and
Delaware law. No stockholder proposal will be considered unless it is in
compliance with the foregoing requirements. If a stockholder does not comply
with the requirements of Rule 14a-4 of the Securities Exchange Act, then the
persons appointed as proxies in the proxy card solicited by the Board of
Directors of new Alliance for meetings of new Alliance's stockholders may
exercise discretionary voting authority to vote in accordance with their best
judgment on any proposal submitted by such stockholder outside of Rule
14a-8.

     (a)    There is no action, proceeding, investigation or inquiry pending or,
to the knowledge of the Alliance Entities, threatened (i) against or affecting

the assets of any of the Alliance Entities and that would result in a Material
Effect.

     (c)    Alliance has no knowledge of any state of facts or of the occurrence

raised by the Internal Revenue Service or other relevant tax authority in any
such examination that has been resolved adversely to any of the Alliance

Service or other relevant tax authority of a material deficiency in any other
taxable year or with respect to any other of the Alliance 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 Alliance Entities for any Taxes.

     (i)    The dissenter believes that the amount paid under W.S. 17-16-1325 or
offered under W.S. 17-16-1327 is less than the fair value of his shares or that
the interest due is incorrectly calculated;

     (ii)   The corporation fails to make payment under W.S. 17-16-1325 within
sixty (60) days after the date set for demanding payment; or

     (iii)  The corporation, having failed to take the proposed action, does not
return the deposited certificates or release the transfer restrictions imposed

                  SUBARTICLE C.  JUDICIAL APPRAISAL OF SHARES

     (S)17-16-1330 COURT ACTION. -- (a)  If a demand for payment under W.S. 17-
16-1328 remains unsettled, the corporation shall commence a proceeding within
sixty (60) days after receiving the payment demand and petition the court to
determine the fair value of the shares and accrued interest.  If the corporation
does not commence the proceeding within the sixty (60) day period, it shall pay
to each dissenter whose demand remains unsettled the amount demanded.

     (b)    The corporation shall commence the proceeding in the district court
of the county where a corporation's principal office, or if none in this state,
its registered office, is located. If the corporation is a foreign corporation
without a registered office in this state, it shall commence the proceeding in
the county in this state where the registered office of the domestic corporation
merged with or whose shares were acquired by the foreign corporation was
located.

     (c)    The corporation shall make all dissenters, whether or not residents
of this state, whose demands remain unsettled parties to the proceeding as in an
action against their shares and all parties shall be served with a copy of the
petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.

     (d)    The jurisdiction of the court in which the proceeding is commenced
under subsection (b) of this section is plenary and exclusive.  The court may
appoint one (1) or more persons as appraisers to receive evidence and recommend
decision on the question of fair value.  The appraisers have the powers
described in the order appointing them, or in the amendment to it.  The
dissenters are entitled to the same discovery rights as parties in other civil
proceedings.

     (e)    Each dissenter made a party to the proceeding is entitled to
judgment for:

                                      B-4
<PAGE>

     (i)    The amount, if any, by which the court finds the fair value of his
shares, plus interest, exceeds the amount paid by the corporation; or

     (ii)   The fair value, plus accrued interest, of his after-acquired shares
for which the corporation elected to withhold payment under W.S. 17-16-1327.


     (S)17-16-1331 COURT COSTS AND COUNSEL FEES. -- (a)  The court in an
appraisal proceeding commenced under W.S. 17-16-1330 shall determine all costs
of the proceeding, including the reasonable compensation and expenses of
appraisers appointed by the court. The court shall assess the costs against the
corporation; except that the court may assess costs against all or some of the
dissenters, in amounts the court finds equitable, to the extent the court finds
the dissenters acted arbitrarily, vexatiously, or not in good faith demanding
payment under W.S. 17-16-1328.

     (b)    The court may also assess the fees and expenses of counsel and
experts for the respective parties, in amounts the court finds equitable:

     (i)    Against the corporation and in favor of any and all dissenters if
the court finds the corporation did not substantially comply with the
requirements of W.S. 17-16-1320 through 17-16-1328; or

     (ii)   Against either the corporation or a dissenter, in favor of any other
party, if the court finds that the party against whom the fees and expenses are
assessed acted arbitrarily, vexatiously, or not in good faith with respect to
the rights provided by this article.

     (c)    If the court finds that the services of counsel for any dissenter
were of substantial benefit to other dissenters similarly situated, and that the
fees for those services should not be assessed against the corporation, the
court may award to these counsel reasonable fees to be paid out of amounts
awarded the dissenters who were benefited.

                              TERMS OF THE OFFER

The following terms apply to the offer. Any references to time refer to London

1.   Acceptance period

(a)  The offer will be open for acceptance until 3:00 p.m. on November 19, 1999.

extend the period of the offer.

2.   Announcements

(a) By 8.30 am on November 22, 1999 new Alliance will make an appropriate
announcement and simultaneously inform the London Stock Exchange of the
position. Such announcement will also state the total number of Alliance shares
and rights over Alliance shares (as nearly as practicable) for which acceptances
of the offer have been received and will specify the percentage of the Alliance
shares represented by such figure. In calculating the number of Alliance shares
represented by acceptances and purchases, there may be included or excluded for
announcement purposes, acceptances and purchases which are not complete in all
respects or which are subject to verification.

3.   Rights of withdrawal

     Acceptances of the offer may be withdrawn at any time prior to the
expiration date of the offer and, unless previously accepted for settlement by
new Alliance, may also be withdrawn at any time after December 19, 1999. Subject
to the foregoing, acceptances will be irrevocable.

     For a withdrawal to be effective, a written, telegraphic, or facsimile
transmission notice of withdrawal must be timely received by IRG plc.  Any
notice of withdrawal must specify the name of the person whose shares are to be
withdrawn, the number of shares to be withdrawn and the name of the registered
holder, if different from that of the person who accepted the offer.  If
certificates for shares to be withdrawn have been delivered or otherwise
identified to the IRG plc, the transfer agent, then prior to the physical
release of the certificates, the name of the registered holder and the serial
numbers shown on the certificates must also be submitted to IRG plc, the
transfer agent.  Withdrawals of acceptances of the offer may not be rescinded
and the holder of any shares properly withdrawn will thereafter be deemed not to
have accepted the offer with respect to those shares.  However, the holder of
the withdrawn may again accept the offer following the procedures described in
Appendix D at any time on or prior to the expiration date of the offer.

4.   Revised offer

     New Alliance will not be entitled to make any revision to the offer.

5.   General

capable of waiver) waived or, where appropriate, have been determined by new
Alliance in its reasonable opinion to be or remain satisfied by 3:00 p.m. London
Time on November 19, 1999 or such later date as Alliance may determine. If the
offer lapses, the offer will cease to be capable of further acceptance and
Alliance Shareholders and new Alliance will cease to be bound by prior
acceptances.


(b) Settlement of the consideration to which any Alliance Shareholder is
entitled under the offer will be implemented in full in accordance with the
terms of the offer and as otherwise set out in this document without regard to

thereafter. Copies of the Form of Acceptance, this proxy statement/prospectus

to be incorporated in the Form of Acceptance constitute part of the terms of the
offer. Words and expressions defined in this document have the same meanings
when used in the Form of Acceptance, unless the context otherwise requires.

(e)  The offer and all acceptances thereof or pursuant thereto and the relevant
Form of Acceptance and all contracts made pursuant thereto and action taken or
made or deemed to be taken or made under any of the foregoing shall be /governed
by and construed in accordance with the laws of England. Execution by or on
behalf of an Alliance Shareholder of a Form of Acceptance will constitute his
submission, in relation to all matters arising out of or in connection with the
offer and the Form of Acceptance, to the jurisdiction of the courts of England
and his agreement that nothing shall limit the right of new Alliance to bring
any action, suit or proceeding arising out of or in connection with the offer
and the Form of acceptance in any other manner permitted by law or in any court
of competent jurisdiction.

(f)  Any omission to despatch the Form of Acceptance, this proxy
statement/prospectus or any notice required to be despatched under the terms of
the offer to, or any failure to receive the same by, any person to whom the
offer is made, or should be made, shall not invalidate the offer in any way.
Subject to paragraph 6 below, the offer extends to any such person and to all
Alliance Shareholders to whom the Form of Acceptance, this proxy
statement/prospectus and any related documents may not be despatched, and such
persons may collect copies of those documents from IRG plc, 390/398 High Road,
Ilford, Essex 1G1 1NQ.

(g)  If the offer does not become unconditional in all respects: (i) the Form of
Acceptance and any share certificate(s) and/or other document(s) of title will

risk of the Alliance Shareholder concerned, to the person or agent whose name
and address is set out in the relevant Box of the Form of Acceptance; and (ii)
IRG plc will, immediately after the lapsing of the offer, give instructions to

of CREST, share certificate(s) and/or other document(s) of title will be given

if received by or on behalf of new Alliance at any place or places or in any
manner determined by new Alliance otherwise than as set out herein or in the
Form of Acceptance.

(j)  A purchase of Alliance shares by new Alliance, its wholly owned
subsidiaries or its nominees (or by a person acting in concert with new Alliance
(or its nominee)) shall be counted towards fulfilling the acceptance condition.

(k)  All communications, notices, certificates, documents of title and
remittances to be delivered by or sent to or from any Alliance Shareholders will
be delivered by or sent to or from them (or their designated agents) at their
risk.

(l)  If sufficient acceptances are received and/or sufficient Alliance shares
are otherwise acquired, new Alliance intends to apply the provisions of section
428 to 430F of the Companies Act 1985 of the United Kingdom to acquire
compulsorily any outstanding Alliance shares and to apply for the cancellation
of Alliance's listing on the Official List.

(m)  Due completion of a Form of Acceptance will constitute an instruction to
new Alliance, on the offer becoming unconditional in all respects, that all
mandates and other instructions or notices recorded in Alliance's records
immediately prior to the offer becoming so unconditional will, unless and until
revoked or varied, continue in full force in relation to new Alliance Common
Stock issued to the relevant Shareholders pursuant to the offer.

(n)  In relation to any acceptance of the offer in respect of a holding of
Alliance shares which are in CREST, new Alliance reserves the right to make such
alterations, additions or modifications to the terms of the offer as may be
necessary or desirable to give effect to any purported acceptance of the offer,
whether in order to comply with the facilities or requirements of CREST or

6.   Overseas Shareholders

(a)  The making of the offer in, or to persons resident in or citizens of,
jurisdictions outside the U.K., U.S. and Canada ("overseas shareholders") may be
affected by the laws of the relevant jurisdictions. Such overseas shareholders
should inform themselves about and observe any applicable legal requirements. It
is the responsibility of any overseas shareholder wishing to accept the offer to
satisfy himself as to the full observance of the laws of the relevant
jurisdiction in connection therewith, including the obtaining of any government,
exchange control or other consents which may be required, or the compliance with
other necessary formalities needing to be observed and the payment on any issue,
transfer or other taxes or duties due in such jurisdiction. Any overseas
shareholder will be responsible for payment of any issue, transfer or other
taxes or other requisite payments due in such jurisdiction by whomsoever payable
and new Alliance and any person acting on its behalf shall be entitled to be
fully indemnified and held harmless by such shareholder for any issue, transfer
or other taxes as such person may be required to pay.

(b)  The availability of new Alliance common stock to overseas shareholders may
be affected by the laws of the relevant jurisdictions. Such overseas
shareholders should inform themselves about and observe any applicable legal
requirements. It is the responsibility of any overseas shareholder acquiring new
Alliance common stock to satisfy himself as to the full observance of the laws
of the relevant jurisdiction in connection therewith, including the obtaining of
any governmental or other consents which may be required, compliance with other
formalities needing to be observed and payment of any issue, transfer or other

(c)  These provisions and any other terms of the offer relating to overseas

                                  APPENDIX D

        PROCEDURE FOR ACCEPTANCE OF THE OFFER BY ALLIANCE SHAREHOLDERS


     All references to time refer to London time.

Completion of Form of Acceptance


     If you hold Alliance shares in both certificated and uncertificated or
CREST form, you should complete a separate Form of Acceptance for each holding.
In addition, you should complete separate Forms of Acceptance for Alliance
shares held in uncertificated form but under different member account IDs and
for Alliance shares held in certificated form but under different designations.
Additional Forms of Acceptance are available from IRG plc, Balfour House,
390/398 High Road, Ilford, Essex 1G1 1NQ (telephone number: 0181 639 2000) in
the case of all Alliance shareholders.  To accept the offer in respect of all
your Alliance shares, you must complete Boxes 1 and 3 and, where appropriate,
Box 5 and, if your Alliance shares are in CREST, Box 4 on the Form of
Acceptance.  In all cases you must sign Box 2 on the Form of Acceptance in the
presence of a witness, who should also sign in accordance with the instructions
printed thereon.  To accept the offer in respect of less than all your Alliance
shares you must insert in Box 1 on the enclosed Form of Acceptance such lesser
number of Alliance shares in respect of which you wish to accept the offer in
accordance with the instructions printed thereon.  You should then follow the
appropriate procedure set out above in respect of such lesser number of Alliance
shares.

Return of Form of Acceptance


     To accept the offer, the completed Form of Acceptance should be returned
(whether or not your Alliance shares are in CREST) signed and witnessed by post
or by hand to IRG plc, 390/398 High Road, Ilford, Essex 1G1 1NQ in the case of
Alliance shareholders with registered addresses in the United Kingdom or
otherwise outside of the United States or Canada, and to Registrar and Transfer
Company as forwarding agent at 10 Commerce Drive, Cranford, NJ 07016 in the case
of all Alliance shareholders with registered addresses in the United States or
Canada, together with the relevant share certificate(s) and/or other document(s)
of title as soon as possible, but in any event so as to arrive no later than
3:00 p.m. on November 19, 1999. No acknowledgment of receipt of documents will
be given by or on behalf of new Alliance. The instructions printed on the Form
of Acceptance are deemed to form part of the terms of the offer.

Additional Procedures For Alliance Shares in Uncertificated Form


     If your Alliance shares are in uncertificated form, you should insert in
Box 4 of the Form of Acceptance the participant ID and member account ID under
which such Alliance shares are held by you in CREST and otherwise complete and
return the Form of Acceptance as described above.  In addition, you should take
(or procure to be taken) the action set out below to transfer the Alliance
shares in respect of which you wish to accept the offer to an escrow balance (a
TTE instruction) specifying IRG plc (in its capacity as a CREST participant
under its participant ID referred to below) as the escrow agent, as soon as
possible and in any event so that the transfer to escrow settles no later than
3:00 p.m. on November 19, 1999.

     If you are a CREST sponsored member, you should refer to your CREST sponsor
before taking any action.  Your CREST sponsor will be able to confirm details of
your participant ID and the member account ID under which your Alliance shares
are held.  In addition, only your CREST sponsor will be able to send the
required TTE instruction to CRESTCo in relation to your Alliance shares.

     You should send or, if you are a CREST sponsored member, instruct your
CREST sponsor to send, a TTE instruction to CRESTCo which must be properly
authenticated in accordance with CRESTCo's specifications and which must
contain, in addition to the other information that is required for a TTE
instruction to settle in CREST, the following details:

     .    the number of Alliance shares to be transferred to an escrow balance;

     .    your member account ID. This must be the same member account ID as
          that inserted in Box 4 of the Form of Acceptance;
<PAGE>

     .    your participant ID. This must be the same participant ID as that
          inserted in Box 4 of the Form of Acceptance;

     .    the member account ID of the escrow agent. This is ALLR;

     .    the participant ID of the escrow agent, in its capacity as CREST
          receiving agent. This is RA06;

     .    the Form of Acceptance reference number. This is the reference number
          that appears at the foot of page 1 of the Form of Acceptance. This
          reference number should be inserted in the first eight characters of
          the shared note field on the TTE instruction. Such insertion will
          enable IRG plc to match the TTE to your Form of Acceptance. You should
          keep a separate record of this reference number for future
          reference;

     .    the intended settlement date. This should be as soon as possible and
          in any event not later than 3:00 p.m. on November 19, 1999; and

     .    Corporate Action Number. This is allocated by CRESTCo and can be
          found by viewing the relevant corporation action details in CREST.

     After completion of the TTE instruction, you will not be able to access the
Alliance shares concerned in CREST for any transaction or charging purposes.  If
the offer becomes or is declared unconditional in all respects, the escrow agent
will transfer the Alliance shares concerned to itself.

     You are recommended to refer to the CREST manual published by CRESTCo for
further information on the CREST procedures outlined above. For ease of
processing, you are requested, wherever possible, to ensure that a Form of
Acceptance relates to only one TTE instruction.

     If no Form of Acceptance reference number, or an incorrect Form of
Acceptance reference number, is included in the TTE instruction, new Alliance
may treat any amount of Alliance shares transferred to an escrow balance in
favor of the escrow agent specified above from the participant ID and member
account ID identified in the TTE instruction as relating to any Form(s) of
Acceptance which relate(s) to the same member account ID and participant ID, up
to the amount of Alliance shares inserted or deemed to be inserted on the
Form(s) of Acceptance concerned.


     You should note that CRESTCo does not make available special procedures in
CREST for any particular corporate action.  Normal system timings and
limitations will therefore apply in connection with a TTE instruction and its
settlement. You should therefore ensure that all necessary action is taken by
you (or by your CREST sponsor) to enable a TTE instruction relating to your
Alliance shares to settle prior to 3:00 p.m. on November 19, 1999.  In this
regard, you are referred in particular to those sections of the CREST manual
concerning practical limitations of the CREST system and timings.

     New Alliance will make an appropriate announcement if any of the details
contained in this section alter for any reason in any respect that is material
to Alliance shareholders.

Alliance share certificates not readily available or lost


     If your Alliance shares are in certificated form but your share
certificate(s) and/or other document(s) of title is/are not readily available or
is/are lost, the Form of Acceptance should nevertheless be completed, signed and
returned so as to arrive no later than 3:00 pm on November 19, 1999, together
with any share certificate(s) and/or other document(s) of title that you have
available, accompanied by a letter stating that the balance will follow or that
you have lost one or more of your share certificate(s) and/or other document(s)
of title. You should then arrange for the relevant share certificate(s) and/or
other document(s) of title to be forwarded as soon as possible thereafter. No
acknowledgment of receipt of documents will be given. In the case of loss, you
should write as soon as possible to IRG plc, 390/398 High Road, Ilford, Essex
1G1 1NQ for a letter of indemnity for lost share certificate(s) and/or other
document(s) of title which, when completed in accordance with the instructions
given, should be returned to IRG plc in the case of Alliance shareholders with a
registered address in the United Kingdom or otherwise outside of the United
States or Canada, and to Registrar and Transfer Company as forwarding agent in
the case of all Alliance shareholders with registered addresses in the United
States or Canada as set out above.

Deposits of Alliance Shares Into and Withdrawals of Alliance Shares From CREST


     Normal CREST procedures (including timings) apply in relation to any
Alliance shares that are, or are to be, converted from uncertificated to
certificated form, or from certificated to uncertificated form, during the
course of the offer (whether any such conversion arises as a result of a
transfer of Alliance shares or otherwise).  Holders of Alliance shares who are
proposing so to convert any such Alliance shares are recommended to ensure that
the conversion procedures are implemented in sufficient time to enable the
person holding or acquiring the Alliance shares as a result of the conversion to
take all necessary steps in connection with an acceptance of the offer (in
particular, as regards delivery of share certificate(s) and/or other document(s)
of title or transfers to an escrow balance as described above) prior to 3:00
p.m. on November 19, 1999.

Validity of Acceptance

     New Alliance reserves the right (subject to the terms of the offer) to
treat as valid in whole or in part any acceptance of the offer which is not
entirely in order or which is not accompanied by the relevant TTE instruction or
(as applicable) the relevant share certificate(s) and/or other document(s) of
title.  In that event, no shares of new Alliance common stock will be issued
under the offer until after the relevant TTE instruction has settled or (as
applicable) the relevant share certificate(s) and/or other document(s) of title
or indemnities satisfactory to new Alliance have been received.

Cautionary Statement Regarding Forward Looking Statements

In the interest of providing the Company's stockholders and potential investors
with certain information regarding the Company's future plans and operations,
certain statements set forth in this Form 10-K relate to management's future
plans and objectives.  Such statements are "forward-looking statements" within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended.  Although any
forward-looking statements contained in this Form 10-K or otherwise expressed by
or on behalf of the Company are, to the knowledge and in the judgement of the
officers and directors of the Company, expected to prove true and to come to
pass, management is not able to predict the future with absolute certainty.
Forward-looking statements involve known and unknown risks and uncertainties
which may cause the Company's actual performance and financial results in future
periods to differ materially from any projection, estimate or forecasted result.
These risks and uncertainties include, among other things, volatility of oil and
gas prices, competition, risks inherent in the Company's oil and gas operations,
the inexact nature of interpretation of seismic and other geological and
geophysical data, imprecision of reserve estimates, the Company's ability to
replace and expand oil and gas reserves, and such other risks and uncertainties
described from time to time in the Company's periodic reports and filing with
the Securities and Exchange Commission.  Accordingly, stockholders and potential
investors are cautioned that certain events or circumstances could cause actual
results to differ materially from those projected, estimated, or predicted.

                                                                               i

                                    PART I

ITEM 1.  BUSINESS

     Alliance Resources PLC (the "Company" or "Alliance") is organized as a
public limited company under the laws of England and Wales.  Alliance is a
London-based holding company of a group ("the Group") whose principal activities
are the acquisition, exploration, development and production of oil and gas
properties.

     All financial data (and, consequently, all oil and gas reserve
information, descriptions of properties and business and all information
associated with financial or reserve information ) prior to the Company's merger
with LaTex Resources, Inc. ("LaTex") on May 1, 1997, described below, has been
restated to reflect LaTex as the predecessor company to the Company.  For
financial, reserve and associated information concerning Alliance prior to its
May 1, 1997 merger with LaTex, reference should be made to the Company's
Registration Statement on Form F-4 (which was filed in its final form with the
Securities Exchange Commission on April 9, 1997 and which contains information
regarding Alliance through January 31, 1997) and to the Company's filing on Form
20-F (which was filed in its final form with the Securities and Exchange
Commission on June 18, 1998).

     Because for corporate law purposes (but not financial accounting
purposes) Alliance is the surviving corporation of the May 1, 1997 merger, all
references to the "Company" both prior and subsequent to May 1, 1997 refer to
Alliance Resources PLC and its subsidiaries unless otherwise indicated.  Unless
the context requires otherwise, all references to "LaTex" include LaTex
Resources, Inc., and its consolidated subsidiaries.

     Alliance was incorporated and registered under the laws of England and
Wales on August 20, 1990.  Alliance's corporate headquarters are at 4200 East
Skelly Drive, Suite 1000, Tulsa, Oklahoma  74135.

RECENT DEVELOPMENTS

     On October 30, 1998, Alliance completed its acquisition (the
"Acquisition") of Difco Limited ("Difco").  Alliance acquired all of the capital
stock of Difco and, indirectly a contract to acquire 10% of Burlington Resources
(Irish Sea) Limited's ("Burlington") interest in the East Irish Sea Properties
("U.K. Interests").  The Difco shareholders received approximately 8.7% of the
outstanding shares of the Company and could receive up to 29.6% of the
outstanding shares of the Company based upon the production from, or reserves
attributable to, the U.K. Interests.

     The Company acquired, through Difco, 10% of Burlington's interest in
the East Irish Sea Properties for cash consideration of approximately
$17,800,000.  In addition, the Company issued to one of its lenders 15,000,000
ordinary shares and loan notes with a face value of $9,750,000 for a total
consideration of $10,000,000 and 545,454 ordinary shares in payment of a fee of
$292,000.  The Company paid another lender a cash fee of $700,000 and granted
the lender warrants to purchase 3,275,000 ordinary shares at a price of 1p per
share and an overriding royalty interest in the U.K. Interests of 0.3% beginning
January 1, 2001.  The overriding royalty interest will entitle the lender to
receive a payment equal to the specified percentage of the net revenues
generated by the U.K. Interests. The overriding royalty interest would have the
effect of reducing the Company's revenues from the U.K. Interests. The Company
also issued to its financial advisors 615,385 ordinary shares in payment of a
fee of $330,000.

     On April 23, 1999, the Company announced the successful drilling and
testing of the 110/2b - R1 well.  The well was the first to be drilled on the
Company's recently acquired East Irish Sea assets and is located in the Dalton
Field. The well was spudded on February 26, 1999, drilled to 4,222 feet, and
suspended on April 12, 1999.  Log analysis estimates 605 feet of gross gas
column to be present in the well.  Production testing from gross perforations
between 3,395 - 3,700 feet achieved flow rates up to 78 MMCFG/D at 730 psig
flowing tubing pressure.

     Also, on April 23, 1999 the Company announced that it had recommended its
recompletion program on its U.S. properties, yielding early success.  Notably,
the Ernest Roberts No. 1 Gas Unit in Hinds County, Mississippi was recompleted
in March 1999.  The well is currently producing at a rate of 1,626 MCFG/D with
35 BOPD.  In addition, the Millie 2-20 well located in Dewey County, Oklahoma,
was recompleted in February, 1999 and is currently producing 560 MCFG/D and 2
BOPD.

                                                                               1
<PAGE>

     On July 23, 1999 the Company announced that the Dalton R2 well has been
successfully reentered and recompleted.  The R2 well tested at a maximum flow
rate of approximately 54 MMSCF/D on a 120/64 inch choke at 772 psig flowing
tubing pressure.  In the East Millom Field, the Millom Q1 well has been
successfully reentered and recompleted.  The Q1 well tested at a maximum flow
rate of 18 MMSCF/D on a 68/64 inch choke at 725 psig flowing tubing pressure.
The Dalton R1, R2 and Millom Q1 wells are in the process of being tied back to
the North Morecambe Bay Platform.  First production is anticipated in August,
1999.

     Effective July 30, 1999, the Company and its principal lender agreed to
amend the terms of its credit agreement to allow for additional immediate
borrowings of $5,000,000, to defer the date of the borrowing base
redetermination from July 31, 1999 to December 31, 1999, and to defer the
repayment date of a portion of the indebtedness from January 31, 2001 to July
31, 2001.

     American Rivers Oil Company ("AROC") and Alliance announced that on July
22, 1999, they entered into a preliminary agreement, under which subject to the
satisfaction of certain of various pre-conditions a new subsidiary of AROC would
make a share for share offer for Alliance.  The principal conditions to the
making of the offer are the filing of a registration statement with the
Securities and Exchange Commission and due diligence conducted by both parties.
If the share offer is completed, it is expected that the shares of the new
company will be quoted on the U.S. OTC Bulletin Board and will not be listed on
the London Stock Exchange.  If the transaction is completed and all the Alliance
shareholders accept the offer, the shareholders of Alliance would hold 98% and
the shareholders of AROC would hold 2% of the enlarged group.

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.

GOVERNMENTAL AND ENVIRONMENTAL REGULATION

     Oil and gas production is subject to regulation under many international
and U.S. Federal and State statutes, rules, orders and regulation. Permits for
drilling, reworking and recompletion operations, drilling bonds and reports
concerning operations are required. Most jurisdictions have regulations
governing conservation matters, establishing maximum rates of production and the
regulation of the spacing, plugging and abandonment of wells.

     Environmental laws and regulations may affect the Company's operations
and costs.  In particular, production and saltwater disposal operations and use
of facilities from treating, processing or otherwise handling hydrocarbons and
wastes therefrom are subject to stringent environmental regulations.
Environmental regulations are subject to frequent change and the Company cannot
predict ongoing costs of compliance or the future impact of such regulations on
operations.

OPERATIONS HAZARDS AND INSURANCE

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

                                                                               2
<PAGE>

EMPLOYEES

     At April 30, 1999, Alliance had 15 management and administrative
employees and 9 technical and operating employees, none of whom belonged to a
union. The employees include 15 people located in its Tulsa, Oklahoma office, 8
people in the Tensaw, Alabama office who conduct lease operations in the
Company's South Carlton Field, and 1 field person in Louisiana.  The Company's
other field activities are accomplished through independent contractors.  The
Company believes its relations with its employees and contractors are excellent.

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 its product
as it becomes available or in transporting its product to those 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.

Gas Marketing

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

ITEM 2.  PROPERTIES

PRODUCTION

     Alliance owns producing properties located in 10 states in the U.S.,
with proved reserves located primarily in the states of Alabama, Louisiana,
Mississippi, Oklahoma, and Texas.  Alliance continuously evaluates the
profitability of its oil, gas and related activities and has a policy of
divesting itself of unprofitable oil and gas properties or areas of operation
that are not consistent with its operating philosophy.

     Alliance operates 144 producing wells (119.6 net) in these areas and
also owns non-operated interests in a further 122 active producing wells and
units (21.9 net).  These properties produced at a gross average rate of 4,300.9
Bbls of oil per day and 59,749.8 Mcf of gas per day (802.6 BBls of oil per day
and 4,353.2 Mcf of gas per day net to the Company's interest) for the year ended
April 30, 1999.  Oil and gas sales from Alliance's producing oil and gas
properties accounted for substantially all of Alliance's revenues for the year
ended April 30, 1999.

     The following summarizes Alliance's principal areas of oil and gas
production activity as of April 30, 1999.

     South Carlton Field, Alabama.  The South Carlton Field is located in
Clarke and Baldwin Counties in southwest Alabama, approximately 50 miles north
of Mobile, Alabama.  The field is situated on the Alabama River, and all crude
oil produced is exported from the field by barge.  Alliance operates 56 active
producing oil wells and three saltwater disposal wells.  Production is from the
Massive and Pilot Sands of the Tuscaloosa Formation at a depth of approximately
6,000 ft.  The field produced at a gross average daily rate of 301.8 Bbls of oil
per day (249.6 Bbls of oil per day net to the Company's interest) for the
duration of the year ended April 30, 1999.  Production from the field was
allowed to fall during the course of 1998 in order to minimize the impact of low
oil prices on the overall profitability of operations and reached a gross
average daily low of 206 Bbls of oil per day in the month of December 1998.
Workover activities which were kept to a minimum in 1998 were stepped up in
early 1999, and many

                                                                               3
<PAGE>

temporarily shut-in wells were returned to production. The field is now
producing consistently at gross daily rates in excess of 400 Bbls of oil per day
and in July 1999 again reached gross production levels of over 500 Bbls of oil
per day.

     Additional infill drilling has been identified in the field, and the
Company believes that the application of horizontal drilling techniques has the
potential to significantly improve recovery per well in view of the heavy
gravity of the oil (12-14/0/ API).  Alliance's working interest in this field is
100%. Net proved reserves to Alliance as of April 30, 1999 were 5,864.6 MBbls of
oil.

     Bolton Field, Mississippi.  The Bolton Field is located in Hinds
County, Mississippi and approximately 18 miles west of Jackson, Mississippi.
Alliance operates 1 active producing well in this field, the Ernest Roberts #1
Gas Unit.  Production is from the Cotton Valley Sands at a depth of over 15,500
ft.  This property produced at a gross average daily rate of 527 Mcf of gas per
day and 14.2 Bbls of oil per day (372.1 Mcf of gas per day and 10.1 Bbls of oil
per day net to the Company's interest) for the duration of the year ended April
30, 1999.

     The well was recompleted in March 1999 in several Cotton Valley Sands
at depths of between 15,590 and 15,916 ft.  The well is currently producing at a
stabilized gross rate of approximately 1,620 Mcf of gas per day and 40 Bbls of
oil per day.  Alliance's working interest in this field is currently 91%.
Additional proved behind pipe potential has been identified in the well and net
proved reserves to Alliance as of April 30, 1999 were 3,619 MMcf of gas and
132.3 MBbls of oil.

     Black Warrior Basin, Mississippi and Alabama.  Alliance owns operated
and non-operated working interests in 51 wells (38 operated and 13 non-operated)
in Lamar, Fayette and Pickens Counties, Alabama and Lee and Chickasaw Counties,
Mississippi.  Production from these wells and units is from multiple sandstones
of Mississippian (Carter, Lewis and Millerella) and Pennsylvanian (Benton and
Coats) age at depths of 1,900 to 4,600 ft.  These properties produced at a gross
average daily rate of 4,046.8 Mcf of gas per day and 318.4 Bbls of oil per day
(1,450.5 Mcf of gas per day and 11.8 Bbls of oil per day net to the Company's
interest) for the duration of the year ended April 30, 1999.  Alliance's working
interest in these properties varies from between 1.8% to 100%.  Significant
proved behind pipe reserves have been identified in the properties and the
majority are scheduled for recompletion over the next few years with the
potential to add significantly to net cash flow.  Net proved reserves to
Alliance as of April 30, 1999 were 14.2 MBbls of oil and 9,698.4 MMcf of gas.

     War-Wink South/East Quito Fields, Texas.  Alliance owns non-operated
working interests in 41 active wells operated by Texaco and Chevron in the War-
Wink South and East Quito Fields in Ward County, Texas.  These fields currently
produce from multiple reservoirs in the Fusselman dolomite (Middle Silurian),
Atoka limestone (Middle Pennsylvanian), and the Wolfcamp and Cherry Canyon
(Lower and Middle Permian) Sands at depths of 6,200 feet to 17,500 feet.  These
properties produced at a gross average daily rate of 9,253.7 Mcf of gas per day
and 548.6 Bbls of oil per day (753.8 Mcf of gas per day and 46.1 Bbls of oil per
day net to the Company's interest) for the duration of the year ended April 30,
1999.  The University 10-18-1U well which was completed in the Fusselman
dolomite produced at a gross average daily rate of 6,175 Mcf of gas per day
throughout the year.  This amounts to approximately 67% of the gross gas
produced from the properties in which Alliance has an interest in these fields.
A number of proved undeveloped drilling locations have been identified on these
properties.  Net proved reserves to Alliance as of April 30, 1999 were 94.7
MBbls of oil and 1,697.2 MMcf of gas.

     Jefferson Island Field, Louisiana.  The Jefferson Island field is
located approximately 12 miles southwest of the town of New Iberia in Iberia
Parish, Louisiana.  Alliance has a working interest in a 525-acre lease on the
south side of Lake Peigner, which is currently being maintained by production
from the Will Drill Resources (Texaco) JISMC #4 well.  This well is now owned by
Continental Resources Limited ("Continental").  Production intervals are known
to exist in the Siphoni Davisi and Discorbis B sandstone reservoirs at depths of
approximately 8,000 to 9,000 ft.  The reservoir traps are combination
structural-stratigraphic traps in a piercement salt dome setting.  However,
Alliance has not yet established production from the property.  A number of
proved undeveloped drilling locations have been identified on the property and
the Company's working interest in this property is currently 100%. Net proved

     The Company entered into a farm-out agreement with Continental on this
property, whereby Continental, at its sole risk and expense, has conducted a 3D
seismic survey and is to drill and complete two wells on the lease to earn a
two-thirds working interest. Continental completed the 3-D seismic survey in
late 1998 and spudded the first well under the farm-out agreement in June 1999.
This well was drilled to a total depth of approximately 10,000 ft. and several
potentially productive pay zones were identified on electric logs in Siphoni
Davisi Sands at depths of 8,500 to 9,000 ft.  Continental is currently
attempting to complete the well in the lowermost potentially productive sand at
a depth of approximately 9,000 ft.

     Tinsley Field, Mississippi.  The Tinsley Field is located in Yazoo
County, Mississippi, and approximately 34 miles northwest of the town of
Jackson, Mississippi.  Alliance operates 5 active producing wells and 2
saltwater disposal wells.  Production is from upper Cretaceous age Eutaw Sands
at depths of around 4,500 ft.  This property produced at a gross average daily
rate of 55.4 Bbls of oil per day (45.4 Bbls of oil per day net to the Company's
interest) for the duration of the year ended April 30, 1999.  The Company has a
working interest in the property of 100%.  One proved undeveloped drilling
location has been identified on the property.  Net proved reserves to Alliance
as of April 30, 1999 were 360.3 MBbls of oil.

     South Elton Field, Louisiana.  The South Elton Field is located
approximately 19 miles north of the town of Jennings in Jefferson Davis Parish,
Louisiana.  Alliance operates 4 active producing oil and gas wells and 2
saltwater disposal wells.  Production is primarily from the Oligocene age sands
of the Homeseekers D Formation at a depth of approximately 9,000 ft.  This
property produced at a gross average daily rate of 140 Bbls of oil per day and
76.7 Mcf of gas per day (99.0 Bbls of oil per day and 45.6 Mcf of gas per day
net to the Company's interest) for the duration of the year ended April 30,
1999.  The Company has a working interest in the property of between 65.3% and
99.6%.  Another operator is currently acquiring a 3-D seismic survey over the
area and Alliance will receive copies of the data acquired over its property
within two months of completion of processing of the data.  One proved
undeveloped drilling location has been identified on the property.  Net proved
reserves to Alliance as of April 30, 1999 were 259.8 MBbls of oil and 86.4 Mcf
of gas.

     Perkins Field, Louisiana.  The Perkins Field is located approximately
4 miles south of the town of De Quincy in Calcasieu Parish, Louisiana.  Alliance
operates 7 active producing wells and 1 saltwater disposal well.  Production is
from various Miocene age sands at depths of 5,000 to 7,500 ft.  The property
produced at a gross average daily rate of 75.1 Bbls of oil per day (58.6 Bbls of
oil per day net to the Company's interest) for the duration of the year ended
April 30, 1999.  The Company has a working interest in the property of 100%.
Net proved reserves to Alliance as of April 30, 1999 were 221.7 MBbls of oil.

     In addition to these properties, the Company has other producing oil
and gas properties located in Alabama, Arkansas, Colorado, Kansas, Louisiana,
Michigan, Mississippi, Montana, Oklahoma and Texas.  These properties produced
at a gross daily rate of 2,847.4 Bbls of oil per day and 45,845.7 Mcf of gas per
day (281.9 Bbls of oil per day and 1,731.1 Mcf of gas per day net to the
Company's interest) for the duration of the year ended April 30, 1999. Net
proved reserves to Alliance, as of April 30, 1999, from these other properties
were 1,328.0 MBbls of oil and 6,520.2 Mcf of gas.

RESERVES

     Lee Keeling and Associates, Inc. ("LKA"), Alliance's independent
petroleum engineering consulting firm, has made estimates of Alliance's oil and
gas reserves at April 30, 1999.  LKA's report covers the estimated present value
of future net cash flows before income taxes (discounted at 10%) attributable to
Alliance's estimated future net cash flows therefrom.

     The quantities of Alliance's proved reserves of oil and natural gas
presented below include only those amounts which 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 which are recoverable commercially at current prices and costs, under
existing regulatory practices and with existing technology.  Accordingly, any
changes in prices, operating and development costs, regulations, technology or
other factors could significantly increase or decrease estimates of Alliance's
proved developed reserves.  Alliance's proved undeveloped reserves include only
those quantities which Alliance reasonably expects to recover from the drilling
of new wells

                                                                               5

based on geological evidence from offsetting wells. The risks of recovering
these reserves are higher from both geological and mechanical perspective than
the risks of recovering proved developed reserves.

     As required by the Securities and Exchange Commission, the estimates
of net proved reserves and proved developed reserves and the estimated future
net revenues from such reserves set forth below, have been made in accordance
with the provisions of Statement of Financial Accounting Standards No. 69,
"Disclosures about Oil and Gas Producing Activities."  Estimated future net cash
flows from proved reserves are determined by using estimated quantities of
proved reserves and the periods in which they are expected to be developed and
produced based on economic conditions at the date of the report.  The estimated
future production is priced at current prices at the date of the report.  The
resulting estimated future cash inflows are then reduced by estimated future
costs to develop and produce reserves based on cost levels at the date of the
report.  No deduction has been made for depletion, depreciation or for indirect
costs, such as general corporate overhead.  The discounted value was computed by
discounting future net revenues at 10% per annum, without deduction for income
taxes.

     The following table sets forth estimates of the proved oil and natural
gas reserves of Alliance at April 30, 1999, as evaluated by LKA.

The following table sets forth amounts as of April 30, 1999 determined in
accordance with the requirements of the applicable accounting standards
pertaining to the estimated future net cash flows from production and sale of
the proved reserves attributable to Alliance's oil and gas properties before
income taxes and the present value thereof. Nymex benchmark prices used in
determining the future U.S. net cash flow estimates at April 30, 1999 were
$18.66 per barrel for oil and $2.35 per MMBtu for gas.  A delivery price of 9.05
pence per therm, equivalent to $1.54 per MMBtu for gas was used in determining
the future U.K. net cash flow estimates at April 30, 1999.

     The estimation of oil and gas reserves is a complex and subjective
process which is subject to continued revisions as additional information
becomes available.  Reserve estimates prepared by different engineers from the
same data can vary widely.  Assumptions have to be made 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 period will continue.  Other, but equally valid, assumptions might
lead to a significantly different final result.  Therefore, the reserve data
presented herein should not be construed as being exact.  Any reserve estimate
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.  The information provided, therefore, does not represent management's
estimate of Alliance's expected future cash flows or value of proved reserves.

     Alliance has filed estimates of proved reserves with the London Stock
Exchange.  These estimates do not differ materially from those contained in this
document.

     For further information on reserves, costs relating to oil and gas
activities, and results of operations from producing activities, see Note 17 to

Oil and Gas Producing Activities incorporated by reference herein.

     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, 12 had multiple completions.

Developed and Undeveloped Acreage

     The following table sets forth the developed and undeveloped leasehold
acreage held by Alliance at April 30, 1999.  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.

     States in which Alliance held developed and undeveloped acreage at
April 30, 1999 include Alabama, Arkansas, Colorado, Kansas, Louisiana,
Mississippi, Montana, New Mexico, North Dakota, Oklahoma, Texas and Wyoming.

At April 30, 1999, Alliance was not participating in the drilling of any oil and
gas wells.

All of Alliance's drilling activities are conducted with independent
contractors. Alliance owns no drilling equipment.

TITLE TO PROPERTIES

     As is customary in the oil and 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 material properties being
acquired.


ITEM 3.  LEGAL PROCEEDINGS

     The Group is a named defendant in lawsuits, and is subject to claims of
third parties from time to time arising in the ordinary course of business.
While the outcome of lawsuits or other proceedings and claims against the Group
cannot be predicted with certainty, management does not expect these additional
matters to have material adverse effect on the financial position or results of
operations or liquidity of the Group.

                                                                               9

     Quotations for shares listed on the London Stock Exchange are not
generally readily available in newspapers or other publication 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 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.

     Alliance has not paid any cash dividends on the Alliance Shares for at
lease the last two complete fiscal years.  In addition, Alliance is now
restricted from paying dividends under the Company's credit agreement with the
Bank of America.

ITEM 6.  SELECTED FINANCIAL DATA

     On May 1, 1997, Alliance completed its acquisition of LaTex.  The
acquisition resulted in the issuance of 21,448,747 shares to the former
shareholders of LaTex compared to the 8,103,816 shares then outstanding.  As a
result, the former LaTex shareholders had a controlling interest in the combined
group and so for accounting and financial reporting purposes, LaTex is treated
as having acquired Alliance ("Reverse Acquisition").  The historical financial
information for all financial periods to April 30, 1997 reflect the results of
operations and assets and liabilities of LaTex.  LaTex's fiscal year end was
July 31, whereas that of Alliance is April 30.

     On October 30, 1998, Alliance completed its acquisition of Difco and
indirectly a contract to acquire an interest in the U.K. Interests.  The results
of operations and assets and liabilities of Difco have been included since the
date of acquisition.

                                                                              12

1)   During the year ended July 31, 1996, the Company ceased its overseas
     exploration activities in both Tunisia and Kazakhstan and wrote off its
     costs relating to these activities of $3,447.

2)   On May 15, 1997, the existing commodity price hedging agreements were
     terminated through a buyout. On October 23, 1997, new commodity price
     hedging agreements were initiated. The loss relating to the buy-out, $1,128
     has been recognized in its entirety in the year ended April 30, 1998.

3)   The miscellaneous expenses in the year ended July 31, 1996 arose from
     litigation in connection with the sale in July 1993 of a subsidiary of the
     Company.

4)   For periods ending on or before April 30, 1997, the weighted average number
     of shares outstanding has been based on the number of Alliance shares
     issued on May 1, 1997, which represent the number of LaTex shares
     outstanding in each of the relevant periods based on the exchange ratio in
     the acquisition of LaTex. The loss for each period is stated after
     deducting dividends on the LaTex preferred stock.


ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

     The Company's acquisition of LaTex on May 1, 1997 has been accounted for as
a "reverse acquisition" of the Company by LaTex. As such, the historical
financial statements and financial information as of and for each of the years
in the two-year period ended July 31, 1996 and for the nine-month period ended
April 30, 1997 are for the business of LaTex alone and include no information
for the Company.

     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 Form 10-K which are presented in
accordance with U.S. GAAP.

     Unless otherwise indicated, the financial information in this Form 10-K has
been prepared in accordance with U.S. generally accepted accounting principles
("U.S. GAAP").  U.S. GAAP differs in certain respects from generally accepted
accounting principles in the U.K. ("U.K. GAAP").  As a result of the Company's
listing on the London Stock Exchange, the Company is required to file reports
with the London Stock Exchange prepared in accordance with U.K. GAAP.

RESULTS OF OPERATIONS

     The factors which most significantly affect results of operations are (i)
the sale prices of crude oil and gas, (ii) the level of total sales volumes,
(iii) the level of lease operating expenses and (iv) the level of and interest
rates on borrowings. Total sales volumes and the level of borrowings are
significantly impacted by the degree of success in efforts to acquire oil and
gas properties and in the ability to maintain or increase production from
existing oil and gas properties through development activities.

     The following table reflects certain historical operating data for the
periods presented.

YEAR ENDED APRIL 30, 1999 COMPARED TO THE YEAR ENDED APRIL 30, 1998

     Total revenues for the year ended April 30, 1999 were $6,234,477 compared
to $10,209,881 for the year ended April 30, 1998. This 39% decrease in total
revenue can be attributed to a 30% decrease in oil sales volumes (primarily at
the South Carlton Alabama field), and a 17% decrease in natural gas sales
volumes. A portion of the decreased sales volumes is due to the sale of non-
operated, non-strategic properties. Additionally there was a 16% decrease in the
average sales price received for oil, and a 24% decrease in the average sales
price received for natural gas. Crude oil contributed 56% and natural gas
contributed 44% of oil and gas production revenues during the year ended April
30, 1999. For the year ended April 30, 1998, crude oil contributed 61% and
natural gas contributed 39% of oil and gas production revenues, respectively.

     Lease operating expenses decreased 44% to $3,096,468 for the year ended
April 30, 1999, compared to $5,505,826 for the year ended April 30, 1998. The
reduction in operating expenses is a result of a reduced property base, lower
expenses in the Alabama operations, and the shutting-in of marginal operated
wells. On an equivalent barrel basis, lease operating expenses decreased by
$1.75 to $5.41 for the year ended April 30, 1999, compared to $7.16 for the year
ended April 30, 1998.

     Depreciation, depletion and amortization expense decreased 36% from
$2,598,066 for the year ended April 30, 1998 to $1,670,711 for the year ended
April 30, 1999. This was due primarily to lower production volumes and reserve
revisions resulting from price declines. On an equivalent barrel basis
depreciation, depletion, and amortization decreased $0.57 to $3.27 for the year
ended April 30, 1999, compared to $3.84 for the year ended April 30, 1998.

     Alliance limits, on a country-by-country basis, the net capitalized cost of
proved oil and gas properties, to estimated future net cash flows from proved
oil and gas reserves discounted at 10 percent, net of related tax effects, plus
the lower of cost or fair value of unproved properties included in the costs
being amortized.  Since the acquisition of the U.K. Interests on October 30,
1998, developments plans have become firmer, drilling and well re-entry and
recompletion result on 3 wells have been reviewed and significant progress has
been made on the development of the Dalton and Millom Fields.  This additional
information indicates that, while the aggregate reserves estimates at the time
of acquisition are confirmed, the reserves are likely to be produced at a slower
rate than originally anticipated and that development costs are likely to be in
excess of those originally anticipated.  These factors have led to an impairment
in value of the U.K. Interests.  The Company intends to sell a significant
portion of its production from the U.K. Interests

                                                                              15

under a term contract which will achieve prices significantly greater than the
spot price of gas at April 30, 1999 (9.05 pence per therm). The Directors are
confident of achieving a price of between 13 and 15 pence per therm. (This is a
forward-looking statement; refer to the Cautionary Statement Regarding Forward
Looking Statements). However, as no contract is yet in place, the Group has
utilized the spot price at April 30, 1999 in calculating the carrying cost limit
resulting in an impairment charge of some $28 million. The charge has no impact
on cash flows from operating activities.

     Interest costs for 1999 increased $780,981, or 25%, from 1998 primarily due
to the revised credit facility put in place to fund the East Irish Sea
acquisition and development. In 1999, Alliance wrote off $869,906 in deferred
loan costs related to the Company's previous credit facility.

     General and administrative expenses for the year ended April 30, 1999 were
$3,486,007 which represents an increase of 3.6% over the $3,363,885 incurred in
the prior fiscal year. On an equivalent barrel basis general and administrative
expenses rose by $1.84 to $6.81 for the year ended April 30, 1999 compared to
$4.97 for the year ended April 30, 1998.

     The net loss for the year ended April 30, 1999 was $34,463,502 ($0.82 per
ordinary share) compared to a net loss of $4,728,923 ($0.15 per ordinary share)
for the year ended April 30, 1998.

YEAR ENDED APRIL 30, 1998 COMPARED TO NINE MONTHS ENDED APRIL 30, 1997

     Total revenues from the Company's operations for the year ended April 30,
1998 were $10,209,881 compared to $5,844,871 for the nine months ended April 30,
1997.  Revenues increased proportionately over the comparable period a year
earlier due principally to the beneficial effect of higher realized gas and
higher oil volumes, offset partially by the absence of marketing margins in the
revenue category.  The higher oil volumes were partially attributable to the
inclusion of Alliance's sales volumes and additional volumes attributable to the
acquisition of the BoA ORRI in the 1998 period following the LaTex Merger.
Although sales volumes for the year ended April 30, 1998, were adversely
affected by a continuing decline in volumes from the LaTex properties during the
initial three months of the period, the remedial work program had a beneficial
impact on volumes from the LaTex properties (discussed below).  In addition, the
inclusion of Alliance's sales volumes from the start of the current reporting
period more than compensated for the initial decline in the LaTex properties.

     The Company concentrated its efforts immediately after the LaTex Merger on
increasing production from eleven existing producing fields operated by LaTex in
the states of Alabama, Mississippi, Oklahoma, Texas and Louisiana.  Workover
operations on these fields commenced in early May 1997 and comprised mainly
returning shut-in wells to production.  Gross production from these eleven
fields was increased from an average of 244 BOE per day in April 1997 to an
average of 980 BOE per day by October 1997.  Most of the production increase
came from remedial workover operations in the South Carlton field in Alabama.
Gross production from this field alone increased from an average of 89 BOE per
day in April 1997 to an average of 575 BOE per day in September 1997.

     Total operating expenses increased proportionately to $12,595,777 for the
year ended April 30, 1998 compared to $8,155,557 for the nine months ended April
30, 1997.  On May 15, 1997, the existing commodity price hedging arrangements
were bought out with a loss of $1,128,000 recognized in its entirety in the year
ended April 30, 1998 as a result of new agreements being initiated on October
23, 1997.  Lease operating expenses increased to $5,505,826 for the year ended
April 30, 1998 compared to $3,117,341 for the nine months ended April 30, 1997.
The year ended April 30, 1998 was impacted by the remedial work program
mentioned above and the inclusion of the Alliance properties partially offset by
lower operating costs due to the sale of non-operated, non-strategic wells.
Depreciation, depletion and amortization increased to $2,598,066 for the 1998
period compared to $1,541,415 due to higher volumes resulting from the inclusion
of Alliance.  General and administrative expenses decreased marginally from
$3,481,003 during the nine months ended April 30, 1997 to $3,363,885 for the
year ended April 30, 1998 primarily due to an employee stock award of $528,125
in the 1997 period.

                                                                              16
<PAGE>

     In addition to the marginal increase in the net operating loss to
$2,385,896 for the year ended April 30, 1998 from $2,310,686 for the nine months
ended April 30, 1997, there was also a proportionate decrease in other
income/expense.  This was the result of higher interest expense taking into
account the additional quarterly payment.

     In summary, due to the above factors, the net loss for the ordinary
shareholders for the year ended April 30, 1998 decreased to $4,728,923 ($0.15
per ordinary share) compared to a net loss of $4,906,946 ($0.30 per ordinary
share) for the nine months ended April 30, 1997.

CAPITAL RESOURCES AND LIQUIDITY

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

CASH FLOWS AND LIQUIDITY

     At April 30, 1999, Alliance reported current assets of $2,451,077 and
current liabilities of $8,072,252, which resulted in a net current deficit of
$5,621,175.

     For the year ended April 30, 1999 and April 30, 1998, Alliance's operating
activities resulted in negative cash flow of $3,991,251 and $5,184,000,
respectively. The Company had a positive cash flow of $2,098,566 for the nine
months ended April 30, 1997.

     Investing activities of Alliance used $24,174,756 as compared to providing
$3,084,970 in net cash flow for the years ended April 30, 1999 and April 30,
1998, respectively.  The 1999 increase was a result of the acquisition of Difco
and the U.K. Interests as well as the capital expenditures for oil and gas
development activities.

     Financing activities provided $28,043,726 for the year ended April 30,
1999, compared to $2,434,660 for the year ended April 30, 1998.  The increase
was due primarily to the issuance of long-term debt of $45,464,123, the issuance
of common stock for $6,360,000, the refinancing of long-term debt of $22,566,762
and the payment of loan acquisition costs of $1,213,635, all in connection with
the Difco and U.K. Interests acquisitions.

     The domestic spot prices of oil and gas have traded, in a volatile manner
over various periods in recent years. To the extent that oil and gas prices are
volatile, material fluctuations in revenues from quarter to quarter can be
expected which, in turn, could adversely affect the Company's ability to service
its debt with its principal bank in a timely manner and to fund its ongoing
operations and could, under certain circumstances, require a write-down of the
book value of the Company's oil and gas reserves.

     The Company continues to experience net losses and working capital
deficits. These factors may indicate the Company will be unable to continue as a
going concern for a reasonable period of time. Despite its negative cash flow,
the Company has been able to secure financing to support its operations to date.
The Company was not in compliance with certain covenants of its loan agreements
at April 30, 1999, however, a waiver has been obtained for such violations.
Agreement has been reached with the Company's principal lender to amend the
terms of its credit agreement to allow for additional immediate borrowings of
$5,000,000, to defer the date of the repayment of a portion of its indebtedness
from January 31, 2001 to July 31, 2001 and to defer the date of the borrowing
base redetermination from July 31, 1999 to December 31, 1999. The amendment does
not change the scheduled repayment dates of other portions of its debt, the
first payment of which is due July 31, 2000.

                                                                              17
<PAGE>

  The Company's continuation as a going concern is dependent upon its ability to
generate sufficient cash flow to meet its obligations on a timely basis, to
continue to comply with the terms of its borrowing agreements, to obtain
additional financing or refinancing as will be required and ultimately to attain
profitability.  Management believes it has a business plan that, if successfully
executed, will achieve these objectives.

CAPITAL EXPENDITURES

  The timing of most of the Company's U.S. capital expenditures is
discretionary.  Currently, there are no material long-term commitments
associated with the Company's U.S. capital expenditure plans.  Consequently, the
Company has a significant degree of flexibility to adjust the level of such
expenditures as circumstances warrant.  The Company primarily uses funds
available under its credit facility and proceeds from the sale of oil and gas
properties to fund capital expenditures, other than significant acquisitions,
and to fund its working capital deficit.  If the Company's internally generated
cash flows should be insufficient to meet its banking or other obligations, the
Company may reduce the level of discretionary U.S. capital expenditures or
increase the sale of non-strategic oil and gas properties in order to meet such
obligations.

  The timing of the Company's U.K. capital expenditures is determined annually
by a budget prepared by Burlington and approved by Alliance.  Currently, there
are material commitments for the 2000 fiscal year.  These commitments will be
met by funds available under the Company's credit facility and internally
generated cash flow.

  The level of the Company's capital expenditures will vary in future periods
depending on energy market conditions and other related economic factors.  As a
result, the Company will continue its current policy of funding capital
expenditures with funds available under its credit facility and internally
generated cash flow.  (This is a forward-looking statement; refer to the
Cautionary Statement Regarding Forward Looking Statements).

FINANCING ARRANGEMENTS

  Alliance entered into a Credit Agreement (the "Alliance Credit Agreement")
with the Bank of America effective May 1, 1997, amending and restating the
Group's previous credit agreement.  A portion of the borrowings under the
Alliance Credit Agreement bore interest, payable monthly, at a rate equal to the
higher of the Bank of America Reference Rate plus 1% and the Federal Funds Rate
plus 1-1/4%.  Another portion of the borrowings bore interest, payable monthly,
at a rate equal to the London Interbank Offered Rate plus 2%.  The rate at April
30, 1998 was 7.875%.  Principal payments were scheduled to commence on October
31, 1998.  The note was scheduled to mature on March 31, 2000.  Amounts
outstanding were secured by mortgages which cover the majority of the Group's
oil and gas properties.

  In connection with the Difco Acquisition, the Company entered into agreements
with Bank of America National Trust & Savings Association ("BoA"), Alliance's
principal lender and EnCap Equity 1996 Limited Partnership and EnCap Capital
Investment Company PLC (collectively "EnCap") providing up to $64,750,000 in
debt, as follows:

                   BoA:
                      Tranche A                    $30,000,000
                      Tranche B                     20,000,000
                      Tranche C                      5,000,000
                                                   -----------
                                                    55,000,000
                   EnCap                             9,750,000
                                                   -----------
                                                   $64,750,000
                                                   ===========

  Tranche A consists of a revolving credit facility secured by a first priority
lien and security interest in all of the oil and gas properties of the Company.
The Company's initial borrowing base is $18,500,000 and is redetermined
semiannually on January 31 and July 31.  Interest is at a rate determined by the
Company from time to time, of either

                                                                              18

(i) the greater of BoA's refernce rate and the federal funds effective rate plus
0.5%, or (ii) 2.0% above the current Interbank rate (7.5% at April 30, 1999).
While any Tranche B loan is outstanding, the preceding margins will be increased
by an additional 0.5% semi-annually on April 26 and on October 26 of each year.
Interest is payable quarterly and principal is due in equal quarterly payments
beginning October 30, 2000 and ending on October 30, 2003.

  Tranche B consists of a credit facility secured by a first priority lien and
security interest in all of the oil and gas properties of the Company.  Interest
is at a rate determined by the Company from time to time, of either (i) BoA's
Tranche B reference rate plus 2.0%, or (ii) 4.0% above the current Interbank
rate (9.0% at April 30, 1999).  The margins for all Tranche B loans will be
increased by an additional 0.5% semi-annually on April 26 and on October 26 of
each year.  Interest is payable quarterly and principal is due in full on
January 31, 2001.

  Tranche C consists of a credit facility secured by a first priority lien and
security interest in all of the oil and gas properties of the Company.  Interest
is at a rate determined by the Company from time to time, of either (i) BoA's
reference rate plus 5.0%, or (ii) 7.0% above the current Interbank rate (12.0%
at April 30, 1999).  Interest is payable quarterly and principal is due in equal
quarterly payments beginning January 31, 2001 and ending on October 30, 2004.
The BoA debt facility contains various covenants, including, but not limited to,
maintenance of minimum current and interest coverage ratios, as defined in the
agreement.

  EnCap debt is unsecured and bears interest at 10%.  Interest is payable
quarterly and principal is due in full on October 30, 2005.  Until October 30,
2001, the Company has the option, in lieu of paying cash, of increasing the
principal amount of the debt by the interest due.

  The Company paid BoA a cash fee of $700,000 and granted BoA warrants to
purchase 3,275,000 ordinary shares at a price of 1p per share.  The fair value
of the warrants $1,335,000 attaching to the debt was treated as a discount.  In
addition, the Company will grant BoA an overriding royalty interest, valued at
the value of the underlying oil and gas reserves, in the U.K. Interests of 0.3%
beginning January 1, 2001.  The overriding royalty interest will entitle BoA to
receive payment equal to the specified percentage of the net revenues generated
by the  U.K. Interests and has the effect of reducing the Company's revenues
from the U.K. Interests.  In connection with obtaining the debt financing from
BoA, the Company was required to enter into commodity price risk management
contract on terms that are mutually agreeable to BoA and the Company for a
period not less than two years with respect to at least 50% of the Company's
estimated producing reserves as of October 31, 1998.  BoA also required the
Company to enter into interest rate risk management contracts providing for a
maximum interest rate of 9.0% on the notional amount projected to be outstanding
on the revolving credit facility.

  The Company was not in compliance with certain covenants of the loan
agreements, which included but were not limited to the maintenance of minimum
levels of working capital and interest coverage. Prior to these violations
causing an event of default, which would have resulted in an acceleration of the
repayment of the loans, the Company obtained waivers from the lenders for all
covenant violations. Effective July 30, 1999 the loan agreement was amended to
revise the borrowing limit of Tranche B to $25,000,000 and reduce the limit of
Tranche A to a similar amount. This enabled the Company to borrow an additional
$5,000,000 as of July 30, 1999. The due date of Tranche B was extended from
January 31, 2001 to July 31, 2001. In addition, the date of the borrowing base
and collateral value redetermination scheduled to occur on July 31, 1999 was
deferred until December 31, 1999.

SEASONALITY

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

                                                                              19
<PAGE>

INFLATION AND PRICES

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

     Prices obtained for oil and gas production depend upon numerous factors
that are beyond the control of the Company including the extent of domestic and
foreign production, imports of foreign oil, market demand, domestic and world-
wide economic and political conditions, and government regulations and tax laws.
Prices for oil and gas have fluctuated significantly in recent years.

     The following table sets forth the average price received by the Company.

                                                     Oil          Gas
                                                  ---------    ----------
     Year ended April 30, 1999                      $13.20        $1.79
     Year ended April 30, 1998                      $15.75        $2.36
     Nine months ended April 30, 1997               $15.34        $1.70

     On October 31, 1998, the Company's commodity price hedge agreements
expired.  During February 1999 the Company completed a transaction to hedge
approximately 65% of its existing monthly gas production by installing a floor
of $1.60/MMBTU and a cap of $2.07/MMBTU.  This will protect the Company from any
severe declines in natural gas prices over the next six months and conversely
limit the benefit of prices in excess of the cap.  During April 1999 the Company
completed a transaction to hedge approximately 40% of its existing monthly oil
production by installing a floor of $12.00/barrel.  This will protect the
Company from any severe declines in oil prices over the next six months.

ISSUES RELATED TO THE YEAR 2000

GENERAL

     The following Year 2000 statements constitute a Year 2000 Readiness
Disclosure within the meaning of the Year 2000 Information and Readiness
Disclosure Act of 1998. The Year 2000 problem has arisen because many existing
computer programs use only the last two digits to refer to a year. Therefore,
these computer programs do not properly recognize and process date-sensitive
information beyond 1999. In general, there are two areas where Year 2000
problems may exist for the Company: information technology such as computers,
programs and related systems ("IT") and non-information technology systems such
as embedded technology on a silicon chip ("Non IT").

THE PLAN

     Alliance's Year 2000 Plan (the "Plan") has four phases: (i) assessment,
(ii) inventory, (iii) remediation, testing and implementation and (iv)
contingency plans. Approximately twelve months ago, the Company began its phase
one assessment of its particular exposure to problems that might arise as a
result of the new millennium. The assessment and inventory phases have been
substantially completed and have identified Alliance's IT systems that must be
updated or replaced in order to be Year 2000 compliant. Remediation, testing and
implementation are scheduled to be completed by September 30, 1999, and the
contingency plan phase of the Plan is scheduled to be completed by October 31,
1999.  Alliance's assessment of the readiness of third parties whose IT systems
might have an impact on Alliance's business has thus far not indicated any
material problems.

                                                                              20
<PAGE>

     With regard to Alliance's Non IT systems, the Company believes that most of
these systems can be brought into compliance on schedule. Alliance's assessment
of third party readiness is not yet completed. Because the potential problem
with Non IT systems involves embedded chips, it is difficult to determine with
complete accuracy where all such systems are located. As part of its Plan, the
Company is making formal and informal inquiries of its vendors, customers and
transporters in an effort to determine the third party systems that might have
embedded technology requiring remediation.

ESTIMATED COSTS

     Although it is difficult to estimate the total costs of implementing the
Plan through January 1, 2000 and beyond, Alliance's preliminary estimate is that
such costs will not be material. To date, the Company has determined that its IT
systems are either compliant or can be made compliant for less than $50,000.
However, although management believes that its estimates are reasonable, there
can be no assurance, for the reasons stated in the next paragraph, that the
actual cost of implementing the Plan would not differ materially from the
estimated costs.

POTENTIAL RISKS

     The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations. This risk exists both as to Alliance's IT and Non IT systems, as
well as to the systems of third parties. Such failures could materially and
adversely affect Alliance's results of operations, cash flow and financial
condition. Due to the general uncertainty inherent in the Year 2000 problem,
resulting in part from the uncertainty of the Year 2000 readiness of third party
suppliers, vendors and transporters, the Company is unable to determine at this
time whether the consequences of Year 2000 failures will have a material impact
on Alliance's results of operations, cash flow or financial condition. Although
the Company is not currently able to determine the consequences of Year 2000
failures, its current assessment is that its area of greatest potential risk in
its third party relationships is in connection with the transporting and
marketing of the oil and gas produced by the Company. The Company is contacting
the various purchasers and pipelines with which it regularly does business to
determine their state of readiness for the Year 2000. Although the purchasers
and pipelines will not guaranty their state of readiness, the responses received
to date have indicated no material problems. The Company believes that in a
worst case scenario, the failure of its purchasers and transporters to conduct
business in a normal fashion could have a material adverse effect on cash flow
for a period of six to nine months. Alliance's Year 2000 Plan is expected to
significantly reduce Alliance's level of uncertainty about the compliance and
readiness of these material third parties. The evaluation of third party
readiness will be followed by Alliance's development of contingency plans.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

     In addition, the dates for completion of the phases of the Year 2000 Plan
are based on Alliance's best estimates, which were derived using numerous
assumptions of future events. Due to the general uncertainty inherent in the
Year 2000 problem, resulting in part from the uncertainty of the Year 2000
readiness of third-parties and the interconnection of computer systems, the
Company cannot ensure its ability to timely and cost-effectively resolve
problems associated with the Year 2000 issue that may affect its operations and
business. Accordingly, shareholders and potential investors are cautioned that
certain events or circumstances could cause actual results to differ materially
from those projected, estimated or predicted.

QUANTITATIVE AND QUALITATIVE ANALYSIS ON MARKET RISK

     The Company's primary market risks relate to changes in interest rates and
in the prices received from sales of oil and natural gas. The Company's primary
risk management strategy is to partially mitigate the risk of adverse changes in

gas prices, by entering into derivative financial and commodity instruments,
including swaps, collars and participating commodity hedges. By hedging only a
portion of its market risk exposures, the Company is able to participate in the
increased earnings and cash flows associated with decreases in interest rates
and increases in oil and natural gas prices; however, it is exposed to risk on
the unhedged portion of its variable rate debt and oil and natural gas
production.

  Historically, the Company has attempted to hedge the exposure related to its
variable rate debt and its forecasted oil and natural gas production in amounts
which it believes are prudent based on the prices of available derivatives and,
in the case of production hedges, the Company's deliverable volumes.  The
Company attempts to manage the exposure to adverse changes in the fair value of
its fixed rate debt agreements by issuing fixed rate debt only when business
conditions and market conditions are favorable.

  The Company does not use or hold derivative instruments for trading purposes
nor does it use derivative instruments with leveraged features.  The Company's
derivative instruments are designated and effective as hedges against its
identified risks, and do not of themselves expose the Company to market risk
because any adverse change in the cash flows associated with the derivative
instrument is accompanied by an offsetting change in the cash flows of the
hedged transaction.

  Personnel who have appropriate skills, experience and supervision carry out
all derivative activity.  The personnel involved in derivative activity must
follow prescribed trading limits and parameters that are regularly reviewed by
senior management.  The Company uses only well-known, conventional derivative
instruments and attempts to manage its credit risk by entering into financial
contracts with reputable financial institutions.

  Following are disclosures regarding the Company's market risk sensitive
instruments by major category.  Investors and other users are cautioned to avoid
simplistic use of these disclosures.  Users should realize that the actual
impact of future interest rate and commodity price movements will likely differ
from the amounts disclosed below due to ongoing changes in risk exposure levels
and concurrent adjustments to hedging positions.  It is not possible to
accurately predict future movements in interest rates and oil and natural gas
prices.

  Interest Rate Risks (non-trading) - the Company uses both fixed and variable
rate debts to partially finance operations and capital expenditures.  As of
April 30, 1999, the Company's debt consists of $39,830,348 in borrowings under
its Credit Agreement which bear interest at a variable rate, and $10,243,775 in
borrowings under its 10% Senior Subordinated Notes which bear interest at a
fixed rate.  The Company hedges a portion of the risk associated with its
variable rate debt through derivative instruments which consist of interest rate
swaps and collars.  Under the swap contracts, the Company makes interest
payments on its Credit Agreement as scheduled and receives or makes payments
based on the differential between the fixed rate of the swap and a floating rate
plus a defined differential. These instruments reduce the Company's exposure to
increases in interest rates on the hedged portion of its debt by enabling it to
effectively pay a fixed rate of interest or a rate, which only fluctuates within
a predetermined ceiling and floor.  A hypothetical increase in interest rates of
two percentage points would cause a loss in income and cash flows of $800,000
during 1999, assuming that outstanding borrowings under the Credit Agreement
remain at current levels.  This loss in income and cash flows would be offset by
a $0 increase in income and cash flows associated with the interest rate swap
and collar agreements that are in effect for 1999.  A hypothetical decrease in
interest rates of two percentage points would cause an increase in the fair
value of $0 in the Company's Senior Subordinated Notes from their fair value at
April 30, 1999.

  Commodity Price Risk (non trading) - The Company hedges a portion of the price
risk associated with the sale of its oil and natural gas production through the
use of derivative commodity instruments, which consist of collars and
participating hedges.  These instruments reduce the Company's exposure to
decreases in oil and natural gas prices on the hedged portion of its production
by enabling it to effectively receive a fixed price on its oil and natural gas
sales or a price that only fluctuates between a predetermined floor and ceiling.
As of July 1, 1999, the Company had entered into derivative commodity hedges
covering an aggregate of 40,000 barrels of oil and 320,000 MMbtu's of

                                                                              22

gas that extend through October 1999. Under these contracts, the Company sells
its oil and natural gas production at spot market prices and receives or makes
payments based on the differential between the contract price and a floating
price which is based on spot market indices. The amount received or paid upon
settlement of these contracts is recognized as oil or natural gas revenues at
the time the hedged volumes are sold. A hypothetical decrease in oil and natural
gas prices of 10% from the price in effect as of April 30, 1999, would cause a
loss in income and cash flows of $383,250 during 1999, assuming that oil and gas
production remain at current levels. This loss in income and cash flows would be
offset by a $0 increase in income and cash flows associated with the oil and
natural gas derivative contracts that are in effect.

Employment Agreements

  Each of Messrs. Keenan, Fenemore, Munchinski, and Schulte 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, September 20, 1996, January 1, 1999 and January 1, 1999, respectively, and
having automatic extensions of the initial term for additional two-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 two-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 twice the annual salary, bonuses and benefits paid
to the executive. 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 of one
lump sum of cash in an amount equal to two and a half times the annual salary,
bonus and benefits paid to the executive.

  The annual salary under each agreement is $180,000 for Mr. Keenan,
(pounds)100,000 for Mr. Fenemore, $140,000 for Mr. Munchinski and $100,000 for
Mr. Schulte, plus any bonuses or other compensation determined by Alliance's
Board of Directors in its discretion.

Compensation of Directors

  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 the
twelve months ended April 30, 1999, the following directors were paid the
indicated fees for their services as directors: Mr. Douglas $16,000, Mr. Kennedy
$16,000, Mr. Samuelson $12,000, Mr. Martinson $12,000 and Mr. Humphries $12,525.

                         Independent Auditors' Report



Board of Directors
Alliance Resources PLC and Subsidiaries


We have audited the consolidated balance sheets of Alliance Resources PLC and
subsidiaries as of April 30, 1998 and 1999 and the related consolidated
statements of operations, stockholders' equity, and cash flows for the nine
months ended April 30, 1997 and the years ended April 30, 1998 and 1999.  These
consolidated financial statements are the responsibility of the Company's
management.  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 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 management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Alliance Resources PLC and subsidiaries as of April 30, 1998 and 1999, and the
results of their operations and their cash flows for the nine months ended April
30, 1997 and the years ended April 30, 1998 and 1999, in conformity with
generally accepted accounting principles in the United States.

The accompanying financial statements have been prepared assuming the Company
will continue as a going concern.  As discussed in Note 1 to the consolidated
financial statements, the Company has suffered recurring losses from operations,
has a net capital deficiency and is obliged to commence repayments on its
borrowings on October 30, 2000. These matters raise substantial doubt about the
Company's ability to continue as a going concern.  Management's plans in regard
to these matters are also described in Note 1.  The consolidated financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

             Notes to Consolidated Financial Statements, Continued


(1)  Organization and Summary of Significant Accounting Policies

     Organization and basis of presentation

     Alliance Resources PLC ("Alliance" or "the Company") and its subsidiaries
     are engaged in the exploration, development and production of oil and gas
     and, until April 30, 1997, oil and gas marketing.  Oil and gas production
     operations are currently conducted principally in Oklahoma, Texas,
     Louisiana, Mississippi and Alabama.  The Company acquired proved
     undeveloped oil and gas interests in the East Irish Sea effective October
     30, 1998 (See Note 2).  Included in oil and gas revenue are sales from 10
     significant producing properties which aggregated approximately $2,700,000,
     $2,210,000, and $2,155,000 for the nine months ended April 30, 1997, and
     years ended April 30, 1998 and 1999, respectively.

     Alliance is a London-based public limited company organized under the laws
     of England and Wales and its shares are listed on the London Stock
     Exchange.  The Company prepares its statutory financial statements in
     accordance with U.K. law and U.K. generally accepted accounting principles.
     These financial statements are prepared in accordance with generally
     accepted accounting principles in the United States.

     On May 1, 1997, Alliance completed its acquisition of LaTex Resources, Inc.
     ("LaTex"), a US independent oil and gas exploration and production company.
     As the LaTex shareholders had a controlling interest in the combined group,
     LaTex was treated as having acquired Alliance ("Reverse Acquisition").
     Accordingly, in the consolidated financial statements for the period
     beginning May 1, 1997, the assets and liabilities of Alliance are recorded
     at fair values while the assets and liabilities of LaTex and its
     subsidiaries are recorded at their historical costs.  The consolidated
     financial statements of the Company for the nine months ended April 30,
     1997, reflect the results of operations and assets and liabilities of LaTex
     and its subsidiaries.   Adjustments have been made to reflect, in that
     period, the changes in the capital structure resulting from the
     acquisition.  Earnings per share have been restated on the basis of the
     number of Alliance shares which, based on the exchange ratio used in the
     acquisition, represents the weighted average number of LaTex common shares
     outstanding in the relevant period.

     In these financial statements the "Group" refers to Alliance and its
     subsidiaries for periods ending on or after May 1, 1997 and to LaTex
     Resources, Inc. and its subsidiaries for periods ending on or before April
     30, 1997.

     Financial Condition

     The accompanying financial statements have been prepared on a going concern
     basis, which contemplates the realization of assets and satisfaction of
     liabilities in the normal course of business.  As shown in the financial
     statements during the nine months ended April 30, 1997 and the years ended
     April 30, 1998 and 1999, the Company incurred losses of $4,389,333;
     $4,728,923; and $34,463,502, respectively, continues to experience working
     capital deficits and is obliged to commence repayments on the borrowings on
     October 30, 2000.  These factors among others may indicate the Company will
     be unable to continue as a going concern for a reasonable period of time.

     The financial statements do not include any adjustments relating to the
     recoverability and classification of liabilities that might be necessary
     should the Company be unable to continue as a going concern.  Despite its
     negative cash flow, the Company has been able to secure financing to
     support its operations to date.  As described in note 7, the Company was
     not in compliance with certain covenants of its loan agreements at April
     30, 1999, but a waiver was obtained for such violations.  The Company has
     also reached agreement with its principal bank to amend certain provisions
     of the loan agreement to allow for additional borrowing capacity under
     Tranche B, to defer the borrowing base redetermination date from July 31,
     1999 to December 31, 1999 and extend the repayment due date to July 31,
     2001.  The amendment does not, however, change the scheduled repayment
     dates of Tranche A which commence on October 30, 2000.

                                                                             F-8

                    ALLIANCE RESOURCES PLC AND SUBSIDIARIES

             Notes to Consolidated Financial Statements, Continued


     The Company's continuation as a going concern is dependent upon its ability
     to generate sufficient cash flow to meet is obligations on a timely basis,
     to continue to comply with the terms of its borrowing agreements, to obtain
     additional financing or refinancing as will be required and ultimately to
     attain profitability.  Management believes it has a business plan that, if
     successfully executed, will achieve these objectives.

     Reporting Currency

     The current operations are in the oil and gas industry in the United States
     and the United Kingdom and are conducted through subsidiaries, LaTex
     Petroleum Corporation, Alliance Resources (USA) Inc., Germany Oil Company,
     Difco Limited, and Source Petroleum Inc.  Transactions are conducted
     primarily in U.K. Sterling and US dollars. The directors consider that the
     US dollar is the functional currency of the Group and the Group's
     consolidated financial statements have been prepared in US dollars.

     Consolidation

     The consolidated financial statements comprise the financial statements of
     the Company and all other companies in which the Group's holding exceeds 50
     percent.  Transactions and balances between group companies are eliminated
     on consolidation.

     Earnings Per Share

     Basic loss per share has been computed by dividing the net loss
     attributable to ordinary shareholders by the weighted average number of
     ordinary shares outstanding during the period.

     The effect of potential common shares (warrants, options and convertible
     subordinated unsecured loan notes) is anti-dilutive.  Accordingly, diluted
     loss per share is not presented.

     Foreign Currency Translation

     The financial statements 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 net assets are reported as a component of
     stockholders' equity(deficit) in accumulated other comprehensive loss.  In
     the underlying financial statements, transactions with third parties are
     translated into the functional currency at the exchange rate prevailing at
     the date of each transaction.  Monetary assets and liabilities denominated
     in currencies other than the functional currency 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 consolidated statement of
     operations.

     The Group's share capital is denominated in sterling and for the purposes
     of the consolidated financial statements, is translated into US dollars at
     the rate of exchange at the time of its issue.

     Revenues

     Revenues represents income from production and delivery of oil and gas,
     recorded net of royalties in kind. The Group follows the sales method of
     accounting for gas imbalances.  A liability is recorded only if the Group's
     excess takes of gas volumes exceed its estimated recoverable reserves from
     the relevant well and no receivable is recorded where the Group has taken
     less than its entitlement to gas production.

                                                                             F-9

             Notes to Consolidated Financial Statements, Continued


     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 costs, the costs of drilling both
     productive and non-productive wells, capitalized interest, 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
     net proved reserve volumes.  Reserve volumes are combined into equivalent
     units using approximate 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 except for sales involving significant reserves where a
     gain or loss is recognized.

     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.  Future estimated net recoverable amounts
     are determined after income taxes, discounting and using prices and cost
     levels at the balance sheet date.

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

     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 write
     off the cost of assets, net of estimated residual values, over their
     estimated useful lives as follows:

                   Fixtures and equipment   -  3 to 7 years
                   Buildings                -  30 years

     Deferred Taxation

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

     Joint Ventures

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

                                                                            F-10

             Notes to Consolidated Financial Statements, Continued


     The effects of redeterminations of equity interests in joint ventures are
     accounted for when the outcome of the redetermination is known.

     Leases

     Rentals under operating leases are charged to the consolidated statement of
     operations on a straight line basis over the lease term.

     Debt Issuance Costs

     Debt issuance costs are initially capitalized as intangible assets and are
     amortized over the term of the debt to which they relate.

     Derivatives

     Changes in value of financial instruments, utilized to hedge commodity
     price and interest rate risk are recognized in the consolidated statement
     of operations when the underlying transactions are recognized.  Changes in
     value of financial instruments which do not meet the criteria to be treated
     as a hedge of an underlying risk are recognized in the consolidated
     statement of operations as they occur.

     The Group's criteria for a derivative instrument to qualify for hedge
     accounting treatment are as follows:
       --the timing or duration, quantum and characteristics of the underlying
         exposure must have been identified with reasonable certainty;
       --changes in the value of the derivative must correlate to a high degree
         with changes in the present value of the exposure under a wide range of
         possible circumstances;
       --the derivative has been designated as a hedge or is a synthetic
         alteration of a specific asset, liability or anticipated transaction;
         and
       --the derivative instrument either: (a) reduces exposure of net income or
         cash flow to fluctuations caused by movements in commodity prices,
         currency exchange rates or interest rates, including fixing the cost of
         anticipated debt issuance; or (b) alters the profile of the group's
         interest rate or currency exposures, or changes the maturity profile of
         the investment portfolio, to achieve a resulting overall exposure in
         line with policy guidelines.

     For any termination of derivatives receiving hedge accounting treatment,
     gains and losses are deferred when the relating underlying exposures remain
     outstanding and are included in the measurement of the related transaction
     or balance.  In addition, upon any termination of the underlying exposures,
     the derivative is marked-to-market and the resulting gain or loss is
     included with the gain or loss on the terminated transaction.  The Group
     may re-designate the remaining derivative instruments to other underlying
     exposures provided the normal criteria are all met.

     Cash Flow Statement

     For the purposes of the consolidated statement of cash flows, the Group
     treats all investments with an original maturity of three months or less to
     be cash equivalents.

     Stock Option Plan

     The Company has adopted Statement of Financial Accounting Standards (SFAS)
     No. 123, Accounting for Stock-Based Compensation, which permits entities to
     recognize as expense over the vesting period the fair value of all stock-
     based awards on the date of grant.  Alternatively, SFAS No. 123 also allows
     entities to continue to apply the provisions of Accounting Principles Board
     (APB) Opinion No. 25, Accounting for Stock-Based

                                                                            F-11

     Compensation, and provide pro forma net income and pro forma earnings per
     share disclosures for employee stock option grants made in future years if
     the fair-value-based method defined in SFAS No. 123 had been applied. The
     Company has elected to apply the provisions of APB Opinion No. 25 and
     provide the pro forma disclosure provisions of SFAS No. 123.

     Accounting Estimates

     In the course of preparing financial statements, management makes various
     assumptions and estimates to determine the reported amounts of assets,
     liabilities, revenue and expenses and in relation to the disclosure of
     commitments and contingencies.  Changes in these assumptions and estimates
     will occur as a result of the passage of time and the occurrence of future
     events and, accordingly, the actual results could differ from the amounts
     estimated.

     Business Segments

     The Group adopted Financial Accounting Standard (FAS) 131 "Segment
     Disclosures and Related Information" during the year ended April 30, 1998.
     Prior to April 30, 1997, the Group sold a portion of its oil and gas
     production volumes through its oil and gas marketing subsidiary although
     the operations and net assets of that subsidiary were not separately
     managed.  The Group considers itself to be involved in one business
     activity and does not meet the criteria established by FAS 131.
     Accordingly, information regarding marketing activities has not been
     included for any periods presented.

     Comprehensive Income (Loss)

     The Company has adopted Financial Accounting Standards Board issued
     Statement of Financial Standards No. 130, "Reporting Comprehensive Income"
     (Statement No. 130).  Statement No. 130 establishes standards for reporting
     and display of comprehensive income and its components in a full set of
     general-purpose financial statements.  The Company has reported accumulated
     other comprehensive loss as a separate line item in consolidated balance
     sheets.  The components of total comprehensive income (loss) for the
     periods consist of net losses and foreign currency translation.

     Significant Differences between U.S. and U.K. Accounting Principles

     The accounting policies used in the preparation of these financial
     statements conform with U.S. generally accepted accounting principles
     ("U.S. GAAP") which differ in certain respects from U.K. generally accepted
     accounting principles ("U.K. GAAP").  Differences which may have a
     significant effect on net loss and shareholders' deficit are set out below.

     (a)  Under U.S. GAAP, ceiling tests are calculated using prices prevailing
          at the year end. Under U.K. GAAP, a reasonable assessment of future
          prices is used. At April 30, 1999, the spot price for gas in the U.K.
          was significantly below management's reasonable expectation of future
          prices resulting in a significantly greater charge under U.S. GAAP
          than under U.K. GAAP.

     (b)  Under U.S. GAAP, the convertible subordinated unsecured loan notes are
          treated as a liability. Under U.K. GAAP, the convertible subordinated
          unsecured loan notes are included as part of shareholders' equity as
          in substance their terms are economically equivalent to warrants with
          a zero strike price and Alliance has no obligation to transfer future
          economic benefit to the holder of the loan notes.

     (c)  Under U.S. GAAP, the shares issued to the vendors of Difco are
          recorded at the more readily determinable value. Under U.K. GAAP, the
          shares are recorded at the value of the underlying interest in the
          East Irish Sea Interests.

     In addition there are a number of other classification and disclosure
     differences which do not impact net loss or shareholders' deficit.

(2)  Acquisition of Difco Limited and U.K. Interests

     On October 30, 1998, Alliance completed its acquisition of Difco Limited
     ("Difco").  Alliance acquired all of the capital stock of Difco and,
     indirectly, a contract to acquire 10% of Burlington Resources (Irish Sea)
     Limited's ("Burlington") interest in the East Irish Sea Properties ("U.K.
     Interests").  The Difco shareholders received 10,000,000 convertible shares
     valued at $7,208,000. Such value was derived based on the value of the
     underlying market value of the shares issued. The shares issued represented
     approximately 8.7% of the outstanding shares of the Company. The former
     Difco shareholders could receive up to 29.6% of the outstanding shares of
     the Company based upon the production from, or reserves attributable to,
     the U.K. Interests. The Company acquired, through Difco, 10% of
     Burlington's interest in the East Irish Sea Properties for cash
     consideration of approximately $17,800,000. The Company issued to its
     financial advisor 615,385 ordinary shares in payment of a fee of $330,000
     incurred in connection with the transactions. The total acquisition cost,
     including transaction costs, was allocated to oil and gas properties.

                                                                            F-13

     after giving effect to certain adjustments, including increased interest
     expense on debt related to the acquisition and amortization of deferred
     loan costs and debt discount.  The pro forma financial information does not
     necessarily reflect the results of operations that would have occurred had
     the Company and Difco constituted a single entity during such periods.

(3)  Acquisition of LaTex

     On May 1, 1997, Alliance, completed its acquisition of LaTex, whereby a
     newly formed wholly-owned subsidiary of Alliance merged with and into LaTex
     with LaTex being the surviving corporation for accounting purposes.  In
     consideration the shareholders and warrant holders of LaTex received an
     aggregate of 21,448,787 shares of Alliance (the "New Alliance Shares") and
     warrants to purchase an additional 1,927,908 New Alliance Shares.

     As a result, after giving effect to a 40-to-1 reverse stock split of the
     Alliance ordinary shares, each shareholder of LaTex on May 1, 1997,
     received 0.85981 ordinary shares for each share of LaTex common stock,
     2.58201 ordinary shares for each share of the LaTex Series A preferred
     stock then held, 6.17632 ordinary shares for each share of LaTex Series B
     preferred stock then held, and a warrant to purchase 0.85981 share for each
     share of LaTex Common Stock subject to warrants.

     The purchase price was arrived at as follows:

       Value of 8,103,816 Alliance shares outstanding                $4,039,339
       Acquisition costs                                                871,000

     The value of the Alliance shares outstanding was arrived at by using the
     share price of LaTex at the time of announcement of the acquisition
     adjusted by the exchange ratio.

     Transaction costs incurred by Alliance reduced the fair value of Alliance's
     monetary assets and liabilities at the date of the acquisition.

     The fair value of the assets and liabilities of the acquired business at
     the effective date of acquisition is as follows:

       Cash                                                         $ 1,460,555

     As discussed in Note 1, the Company utilizes the full cost method of
     accounting for its oil and gas operations and performs a "ceiling test."
     The ceiling test limits the costs accumulated in respect of each cost pool
     to net amounts that can be recovered from the estimated production of
     proved reserves.  The net amounts recovered are determined utilizing a 10%
     discount factor and pricing and cost levels at the balance sheet date.

     The U.K. Interests consist of proven reserves and the current development
     program is being conducted to produce these reserves.  Although the Company
     intends to enter into term gas delivery contracts which would be expected
     to be at prices above the spot price at April 30, 1999, the Group does not
     have contracts in place at April 30, 1999 with purchasers and, accordingly,
     has utilized the spot market price to value such interests. The utilization
     of these factors has resulted in a ceiling test write-down of approximately
     $28,000,000 for U.S. GAAP purposes.

(5)  Financial Instruments

     The carrying value of cash and cash equivalents, accounts receivables and
     accounts payable approximate the estimated fair value of those financial
     instruments due to their short maturities.  The estimated fair value of the
     interest rate swap agreement, based on current market rates, approximated a
     net payable of $445,767 and $248,884 at April 30, 1998 and 1999,
     respectively.  The estimated fair value of the commodity derivative
     instruments approximates a net receivable of $409,395 at April 30, 1998 and
     a net payable of $128,479 at April 30, 1999.  The carrying value of long-
     term debt approximates to the fair value, as advised by the Group's
     bankers.  See note 15.

     Fair value is defined as the amount at which the instrument could be
     exchanged in a current transaction between willing parties.

                                                                            F-15

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

     The Group has net operating loss carryovers to offset future taxable
     earnings of approximately $44,000,000, including approximately $36,000,000
     of losses limited under Section 382 of the Internal Revenue Code.  If not
     previously utilized or limited, the net operating losses will expire in
     varying amounts from 2004 to 2019.

     Alliance entered into a Credit Agreement (the "Alliance Credit Agreement")
     with the Bank of America effective May 1, 1997, amending and restating the
     Group's previous credit agreement.  A portion of the borrowings under the
     Alliance Credit Agreement bore interest, payable monthly, at a rate equal
     to the higher of the Bank of America Reference Rate plus 1% and the Federal
     Funds Rate plus 1-1/4%.  Another portion of the borrowings bore interest,
     payable monthly, at a rate equal to the London Interbank Offered Rate plus
     2%.  The rate at April 30, 1998 was 7.875%.  Principal payments were
     scheduled to commence on October 31, 1998.  The note was scheduled to
     mature on March 31, 2000.  Amounts outstanding were secured by mortgages
     which cover the majority of the Group's oil and gas properties.

     In connection with the Difco Acquisition (See Note 2), the Company entered
     into agreements with Bank of America National Trust & Savings Association
     ("BoA"), Alliance's principal lender and EnCap Equity 1996 Limited

     Tranche A consists of a revolving credit facility secured by a first
     priority lien and security interest in all of the oil and gas properties of
     the Company.  The Company's initial borrowing base is $18,500,000 and is
     redetermined semiannually on January 31 and July 31.  Interest is at a rate
     determined by the Company from time to time, of either (i) the greater of
     BoA's reference rate and the federal funds effective rate plus 0.5%, or
     (ii) 2.0% above the current Interbank rate (7.5% at April 30, 1999).
     While any Tranche B loan is outstanding, the preceding margins will be
     increased by an additional 0.5% semi-annually on April 26 and on October 26
     of each year. Interest is payable quarterly and principal is due in equal
     quarterly payments beginning October 30, 2000 and ending on October 30,
     2003.

     Tranche B consists of a credit facility secured by a first priority lien
     and security interest in all of the oil and gas properties of the Company.
     Interest is at a rate determined by the Company from time to time, of
     either (i) BoA's Tranche B reference rate plus 2.0%, or (ii) 4.0% above the
     current Interbank rate (9.0% at April 30, 1999).  The margins for all
     Tranche B loans will be increased by an additional 0.5% semi-annually on
     April 26 and on October 26 of each year.  Interest is payable quarterly and
     principal is due in full on January 31, 2001.

     Tranche C consists of a credit facility secured by a first priority lien
     and security interest in all of the oil and gas properties of the Company.
     Interest is at a rate determined by the Company from time to time, of
     either (i) BoA's reference rate plus 5.0%, or (ii) 7.0% above the current
     Interbank rate (12.0% at April 30, 1999).  Interest is payable quarterly
     and principal is due in equal quarterly payments beginning January 31, 2001
     and ending on October 30, 2004.  The BoA debt facility contains various
     covenants, including, but not limited to, maintenance of minimum current
     and interest coverage ratios, as defined in the agreement.

     EnCap debt is unsecured and bears interest at 10%.  Interest is payable
     quarterly and principal is due in full on October 30, 2005.  Until October
     30, 2001, the Company has the option, in lieu of paying cash, of increasing
     the principal amount of the debt by the interest due.

     The Company paid BoA a cash fee of $700,000 and granted BoA warrants to
     purchase 3,275,000 ordinary shares at a price of 1p per share.  The fair
     value of the warrants, $1,335,000, attaching to the debt was treated as a
     discount.  In addition, the Company granted BoA an overriding royalty
     interest, valued at the value of the underlying oil and gas reserves, in
     the U.K. Interests of 0.3% beginning January 1, 2001.  The overriding
     royalty interest will entitle BoA to receive payment equal to the specified
     percentage of the net revenues generated by the  U.K. Interests.  In
     connection with obtaining the debt financing from BoA, the Company was
     required to enter into commodity price risk management contract on terms
     that are mutually agreeable to BoA and the Company for a period not less
     than two years with respect to at least 50% of the Company's estimated
     producing reserves as of October 31, 1998.  BoA also required the Company
     to enter into interest rate risk management contracts providing for a
     maximum interest rate of 9.0% on the notional amount projected to be
     outstanding on the revolving credit facility (See Note 2).

     In connection with the issuance of the EnCap debt, the Company sold EnCap
     15,000,000 ordinary shares with a fair value of $6,360,000 for cash
     consideration.  The difference was treated as a discount on the debt.  The
     Company also issued EnCap Investments L.C. 545,454 shares in consideration
     of a fee of $292,000.

     The Company was not in compliance with certain covenants of the loan
     agreements, which included but were not limited to the maintenance of
     minimum levels of working capital and interest coverage. Prior to these
     violations causing an event of default, which would have resulted in an
     acceleration of the repayment of the loans, the Company obtained waivers
     from the lenders for all covenant violations. Effective July 30, 1999, the
     loan agreement was amended to revise the borrowing limit of Tranche B to
     $25,000,000 and reduce the limit of Tranche A to a similar amount. The due
     date of Tranche B was extended from January 31, 2001 to July 31, 2001. In
     addition, the date of the borrowing base and collateral value
     redetermination, scheduled to occur on July 31, 1999, was deferred until
     December 31, 1999.

     The revised schedule of contractual maturities of long-term debt at April
     30, 1999 are as follows and do not include $5,000,000 borrowed under
     Tranche B subsequent to year end which is repayable during the year ending
     April 30, 2002:

(8)  Savings and Profit Sharing Plan

     The Group maintains an employee savings and profit sharing plan (the Plan)
     which covers substantially all of its employees.  The Plan is comprised of
     a 401(k) saving portion and a noncontributory defined contribution portion.
     Employees are qualified to participate after approximately one year of
     service.  Participating in the 401(k) plan is voluntary, and the Group
     matches contributions up to six percent of the employees' salary at a rate
     of 50 percent of the employee's contribution.  The Group contributed
     $8,481, $9,243, and $17,523 to the plan during the nine months ended April
     30, 1997, and the years ended April 30, 1998 and 1999, respectively.

     The noncontributory portion of the Plan allows the Group to share annual
     profits with employees.  Annual payments to the Plan are elective.
     Management elected to make no contributions to the Plan for the nine months
     ended April 30, 1997 and the years ended April 30, 1998 and 1999.  The
     Group is under no obligation to make contributions to the Plan in the
     future.

(9)  Capital Stock

     On May 1, 1997, the Company's share capital was consolidated such that
     every 40 ordinary shares of 1 pence each were consolidated into 1 ordinary
     share of 40 pence.  All prior capital stock amounts have been restated to
     reflect this reverse stock split.  At the same date, the Company issued
     21,448,747 ordinary shares of 40 pence each to the holders of the issued
     ordinary shares and preference shares of LaTex outstanding at that date.

     On October 30, 1998, the Company entered into a capital reorganization plan
     that subdivided each ordinary share into one new ordinary share with a par
     value of 1 pence and 39 deferred shares with a par value of 1 pence each.
     The resulting ordinary shares have the same rights as the ordinary shares
     at 40 pence each.  The deferred shares have no substantive rights, are not
     represented by certificates issued to shareholders, and may be redeemed by
     the Company by the payment of a total of 1 pence for all of the deferred
     shares.

(10) Stock Option Plans

     Effective October 21, 1996, each holder of options granted under the
     Group's 1993 Incentive Stock Plan agreed to terminate all options held and
     receive grants of 1,690,000 Restricted shares of LaTex Common Stock which,
     on May 1, 1997, was exchanged for Alliance shares.  The Group recognized an
     employee bonus of $528,125 related to this transaction based on the market
     value of LaTex's stock on the date of grant.  No tax gross up rights were
     granted in connection with the issue of the Restricted Stock.

                                                                            F-19

     Since May 1, 1997, the Group operates two employee share option schemes.
     Both schemes have similar terms, the principal terms being:
     --  any director or employee may be granted options over Shares;
     --  the subscription price will be no less than market price at the date
         of grant;
     --  options granted to an individual are limited such that the aggregate
         market value of shares subject to option taken together with the
         aggregate market value of shares which have been acquired under rights
         granted under the schemes in the previous ten years does not exceed
         four times cash salary;
     --  the exercise of options may be subject to performance tests. Long term
         options (exercisable after 5 years) may be subject to growth in
         earnings per share over the immediately preceding five years matching,
         exceeding growth in earnings per share of the companies ranked in the
         top 25 of the FTSE-100 share index, or growth in the Company's share
         price during the five year exercise period.

     A summary of the status of the share option schemes is as follows:

                                        Shares       Weighted average
                                                      service price
                                       ---------  ----------------------
          As at May 1, 1997                    -                 -
             Granted                     675,000        24.5 pence
             On acquisition of LaTex     237,500          80 pence
                                       ---------
          As at April 30, 1998           912,500        38.9 pence
             Granted                   2,365,000        13.5 pence
             Cancelled                  (175,000)         80 pence
                                       ---------
          As at April 30, 1999         3,102,500        17.2 pence
                                       =========

     Included in the options granted during the year ended April 30, 1999 were
     1,700,000 long-term options which were subject to the Company's share price
     increasing three-fold during the five year exercise period of the options.

     The Group's accounting policy for compensation cost is in line with
     Accounting Principles Board Opinion 25. Accordingly, compensation cost has
     not been recognized for share option plans except to deal with any
     discounts on option exercise prices, compared with market prices at the
     measurement date.  For the year ended April 30, 1998, had compensation
     costs been charged against income based on the fair value at the grant-
     dates for awards under the share option plans, consistent with Statement of
     Financial Accounting Standards No. 123, the net loss and net loss per share
     would not have been materially different.  This was determined using the
     Black Scholes option pricing model utilizing the following assumptions:

             Risk free interest rate           5.3%
             Expected life                     10 years
             Volatility                        5.93%

     At April 30, 1999, the Company also had outstanding 50,000 options to
     purchase shares at 300 pence per share which have been issued other than
     pursuant to the employee share options schemes.

                                                                            F-20

(11) Warrants

     On May 1, 1997 the Company issued warrants to subscribe for 1,927,908
     ordinary shares of 40 pence each in exchange for the then outstanding
     warrants to subscribe for ordinary shares in LaTex.  For periods ended on
     or before April 30, 1997, the warrants outstanding reflect the Alliance
     warrants issued on May 1, 1997, as though issued at the date of issue of
     the LaTex warrants for which the Alliance warrants were exchanged.

     Warrants to subscribe for 1,210,938 ordinary shares were issued to Bank of
     America as part consideration for the acquisition of the overriding royalty
     interest (see note 3).  At April 30, 1998, the Company had outstanding
     2,916,527 warrants.

     Warrants to subscribe to 3,275,000 common shares at a price of 1 pence per
     share were issued to Bank of America in connection with the Difco
     acquisition (see Note 7).

     In November, 1998, warrants to purchase 1,112,378 Ordinary Shares at a
     price equal to the sterling equivalent of $4.94 expired.

(12) Convertible Subordinated Unsecured Loan Notes

     At April 30, 1998 and 1999 the Group had outstanding loan notes convertible
     into 1,193,581 ordinary shares of which loan notes convertible into
     1,078,125 ordinary shares were issued in part consideration for the
     acquisition of the overriding royalty interest amounting to $1,400,700 (see
     note 3) and loan notes convertible into 115,456 ordinary shares were issued
     to settle restructuring and arrangement fees of $150,000 in connection with
     the LaTex acquisition.  The loan notes, which are non-interest bearing, are
     convertible by the holders (on the payment of a nominal cash consideration)
     any time up to ten years following their date of issue. They are
     convertible in the following six months on like terms at the option of the
     Company. Any loan notes not converted prior to the date ten years and six
     months from issue will be repaid on that date at an amount equal to twice
     the amount paid up on the notes.

(13) Contingencies and Commitments

     The Group is a named defendant in lawsuits, and is subject to claims of
     third parties from time to time arising in the ordinary course of business.
     While the outcome of lawsuits or other proceedings and claims against the
     Group cannot be predicted with certainty, management does not expect these
     additional matters to have material adverse effect on the financial
     position or results of operations or liquidity of the Group.

     The Group leases office space and certain property and equipment under
     various lease agreements.  As of April 30, 1999, future minimum lease
     commitments were approximately as follows:

                       2004                      16,964

     Rent expense under all operating leases was $160,780, $252,627, and
     $251,447 during the nine months ended April 30, 1997, and the years ended
     April 30, 1998 and 1999, respectively.

(14) Related Party Transactions

     The Group, prior to May 1, 1997, has made loans to certain officers,
     directors and stockholders.  During the nine months ended April 30, 1997,
     the board of directors forgave $391,218, of notes and accrued interest, due
     from directors and former officers of the Group.  This amount is included
     in general and administrative expenses.

     During the year ended April 30, 1998, the Company received $123,000 of
     proceeds from the sale of 10,351,966 shares in the Company which had
     previously been owned by the former Chief Executive of the Company.  The
     right to receive the proceeds from the sale of the shares arose from a
     settlement agreed between the Company and Mr. O'Brien following the
     discovery that the Company had suffered a financial loss as a result of a
     number of transactions involving Mr. O'Brien or parties connected with him.

(15) Derivatives

     Oil and Gas

     Effective May 15, 1997, the Group terminated a previously existing oil and
     gas pricing derivative at a cost of $1,128,000 settled by an increase in
     the Bank of America loan. The loss relating to the buy-out was recognized
     in its entirety during the year ended April 30, 1998, consequent upon the
     Group entering into a new price protection agreement.

     On October 23, 1997, the Group entered into commodity price hedge
     agreements to protect against price declines which may be associated with
     the volatility in oil and gas spot prices.  The commodity price hedges were
     achieved through the purchase of put options (floors) by the Group, and the
     associated premium cost was funded by additional drawdowns under the
     current credit agreement.  The commodity price hedges covered 32,000 bbls
     and 100,000 MMBTUs per month for the year to October 31, 1998, and covered
     in excess of 90% of the Group's current monthly sales volumes.  The floors
     equated to approximately $18.50/bbl Nymex WTI contract and $2.20/MMBTU
     Nymex Natural Gas contract.  On October 31, 1998, the Group's commodity
     price hedge agreements expired.

     During February 1999, the Company completed a transaction to hedge
     approximately 65% of its existing monthly gas production by installing a
     floor of $1.60/MMBTU and a cap of $2.07/MMBTU (NYMEX Natural Gas).  During
     April 1999, the Company completed a transaction to hedge approximately 40%
     of its existing monthly oil production by installing a floor of
     $12.00/barrel (NYMEX WTI).  This commodity price hedge agreement will
     protect the Company from any severe declines in oil and gas prices until
     expiration on October 31, 1999.

                                                                            F-22

     Interest

     The Group is required, by agreement with its primary lender (see Note 7) to
     participate in an interest rate protection program, for interest on the
     debt payable to the primary lender until March 31, 2000.  Interest is
     hedged to achieve a fixed rate of 7.49%  calculated on a monthly basis
     based on a fixed amortization schedule determined on loan origination.  The
     notional principal is reduced each month by $365,000.  The notional
     principal outstanding at April 30, 1999 was $13,784,000 and this will have
     reduced at termination to $9,769,000.  The hedging gains/losses are
     included in interest expense.

(16) Disposition of Oil and Gas Properties

     During the nine months ended April 30, 1997 and the years ended April 30,
     1998 and 1999, the Group sold oil and gas properties for approximately
     $1,500,000, $5,600,000 and $1,742,000, respectively.  Proceeds of such
     sales were credited to the full cost pool.

     Estimated Quantities of Proved Oil and Gas Reserves

     The estimates of proved oil and gas reserves were prepared by independent
     petroleum engineers.  The Group emphasizes that reserve estimates are
     inherently imprecise.  Accordingly, the estimates are expected to change as
     more current information becomes available.  In addition, a portion of the
     Group's proved reserves are undeveloped, which increases the imprecision
     inherent in estimating reserves which may ultimately be produced.

     Proved reserves are estimated quantities of crude oil, natural gas, and
     natural gas liquids which geological and engineering data demonstrate with
     reasonable certainty to be recoverable in future years from known
     reservoirs under existing economic and operating conditions.  Proved
     developed reserves are those which are expected to be recovered through
     existing wells with existing equipment and operating methods.

     The following is an analysis of the Group's proved oil and gas reserves.

     Discounted Future Net Cash Flows

     In accordance with Statement of Financial Accounting Standards No. 69,
     estimates of the standardized measure of discounted future cash flows were
     determined by applying period-end prices, adjusted for fixed and
     determinable escalations, to the estimated future production of year-end
     proved reserves.  Future cash inflows were reduced by the estimated future
     production and development costs based on period-end costs to determine
     pre-tax cash inflows over the Group's tax basis in the associated proved
     oil and gas properties.  Net operating losses, credits and permanent
     differences were also considered in the future income tax calculation.
     Future net cash inflows after income taxes were discounted using a 10%
     annual discount rate to arrive at the Standardized Measure.

     Future income tax expenses are estimated using the statutory tax rate of
     34% and 30% in the United States and United Kingdom, respectively.
     Estimates for future general and administrative and interest expense have
     not been considered.

     The estimated standardized measure of discounted future cash flows (in
     thousands) follows:

           Cautionary Statement Regarding Forward Looking Statements

In the interest of providing the Company's stockholders and potential investors
with certain information regarding the Company's future plans and operations,
certain statements set forth in this Form 10-Q relate to management's future
plans and objectives.  Such statements are "forward-looking statements" within
the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended.  Although any
forward-looking statements contained in this Form 10-Q or otherwise expressed by
or on behalf of the Company are, to the knowledge and in the judgment of the
officers and directors of the Company, expected to prove true and to come to
pass, management is not able to predict the future with absolute certainty.
Forward looking statements involve known and unknown risks and uncertainties
which may cause the Company's actual performance and financial results in future
periods to differ materially from any projection, estimate or forecasted result.
These risks and uncertainties include, among other things, volatility of oil and
gas prices, competition, risks inherent in the Company's oil and gas operations,
the inexact nature of interpretation of seismic and other geological and
geophysical data, imprecision of reserve estimates, the Company's ability to
replace and expand oil and gas reserves, and such other risks and uncertainties
described from time to time in the Company's periodic reports and filings with
the Securities and Exchange Commission.  Accordingly, stockholders and potential
investors are cautioned that certain events or circumstances could cause actual
results to differ materially from those projected, estimated, or predicted.

A.  Summary of Significant Accounting Policies

Basis of Presentation
- ---------------------

Alliance Resources PLC (the "Company" or "Alliance") is organized as a public
limited  company under the laws of England and Wales.  Alliance is a holding
company of a group whose principal activities are the exploration, development,
and production of oil and gas and the acquisition of producing oil and gas
properties.  Alliance was incorporated and registered under the laws of England
and Wales on August 20, 1990.

The condensed consolidated financial statements of Alliance Resources PLC and
its wholly-owned subsidiaries (the "Company") reflect all adjustments which are,
in the opinion of management, necessary to present fairly the financial
position, results of operations and cash flows of the Company as of July 31,
1999, and for all interim periods presented.  All adjustments are normal
recurring accruals.

Certain information and disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted.  These condensed consolidated financial statements should
be read in conjunction with the Company's April 30, 1999 audited consolidated
financial statements and notes thereto contained in the Company's Annual Report
to Stockholders for the year ended April 30, 1999.  The results of operations
for the period ended July 31, 1999, are not necessarily indicative of the
operating results to be achieved for the full year.

B.  Significant Events

The Company continues with its development activities in the East Irish Sea.
During the recent quarter, $4.288 million has been spent on capital expenditures
relating to these properties, financed primarily with drawdowns from the
Company's debt facility.  On July 23, 1999 the Company announced that the Dalton
R2 well was successfully reentered and recompleted.  The R2 well tested at a
maximum flow rate of approximately 54 MMSCF/D on a 120/64 inch choke at 772 psig
flowing tubing pressure.  In the East Millom Field, the Millom Q1 well has been
successfully reentered and recompleted.  The Q1 well tested at a maximum flow
rate of 18 MMSCF/D on a 68/64 inch choke at 725 psig flowing tubing pressure.
The Dalton R1, R2 and Millom Q1 wells have been tied back to the North Morecambe
Bay Platform, and first production began on August 10, 1999.

Effective July 30, 1999, the Company and its principal lender agreed to amend
the terms of its credit agreement to allow for additional immediate borrowings
of $5,000,000, to defer the date of the borrowing base redetermination from July
31, 1999 to December 31, 1999, and to defer the repayment date of a portion of
the indebtedness from January 31, 2001 to July 31, 2001.

American Rivers Oil Company ("AROC") and Alliance announced that on July 22,
1999, they entered into a preliminary agreement, under which, subject to the
satisfactory completion of various pre-conditions, a new subsidiary of AROC
would make a share for share offer for Alliance.  The principal conditions to
the making of the offer are the filing of a registration statement with the
Securities and Exchange Commission and due diligence conducted by both parties.
If the share offer is completed, it is expected that the shares of the new
company will be quoted on the U.S. OTC Bulletin Board and will not be listed on
the London Stock Exchange.  If

                                       7

the transaction is completed and all the Alliance shareholders accept the offer,
the shareholders of Alliance would hold 98% and the shareholders of AROC would
hold 2% of the enlarged group.

Item 2.  Management's Discussion and Analysis of Financial Condition and
         Results of Operations

Results of Operations
- ---------------------

The following is a discussion of the results of operations of the Company for
the three months ended July 31, 1999.

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

</TABLE>

Average sales prices received by the Company for oil and gas have historically
fluctuated significantly from period to period.  Fluctuations in oil prices
during these periods reflect market uncertainties as well as concerns related to
the global supply and demand for crude oil.  Average gas prices received by the
Company fluctuate generally with changes in the spot market for gas.  Relatively
modest changes in either oil or gas significantly impact the Company's results
of operations and cash flow and could significantly impact the Company's
borrowing capacity.

Three Months Ended July 31, 1999 compared to the Three Months Ended
- -------------------------------------------------------------------
July 31, 1998
- -------------

Total revenues from the Company's operations for the quarter ended July 31, 1999
were $1,486,861 compared to $1,917,966 for the quarter ended July 31, 1998.
Revenues decreased significantly over the comparable period a year earlier due
principally to lower gas sales volumes and realized oil prices, property
disposals and the depletion of producing reserves.

Net gas sales volumes decreased 11% from the same period in 1998. The remainder
of the volume decrease is attributable to property sales completed during the
quarter ended July 31, 1998.

Total operating expenses increased to $4,095,204 for the quarter ended July 31,
1999 compared to $2,119,070 for the same period in 1998.  This increase was
primarily due to impairment of the U.K. properties.  Lease operating expenses
were higher at $956,927 for the three month period ending July 31, 1999 compared
to $859,453 for the same period in 1998 due to an increase of $280,000 in
workover expenses from the 1998 period. Depreciation, depletion and amortization
decreased to $402,355 from $509,355 a year earlier primarily as a result of
lower sales volumes.  General and administrative expenses decreased from
$750,262 during the quarter ended July 31, 1998 to $736,098 for the quarter
ended July 31, 1999.  The decrease is a result of continuing efforts by
management to reduce corporate overhead expenses.

A net operating loss of $3,707,444 was realized for the quarter ended July 31,
1999 compared to a net operating loss of $850,987 for the same period in 1998.

In summary, due to the above factors, the net loss for the quarter ended July
31, 1999 increased to $3,707,444 ($0.07 per share) compared to a net loss of
$850,987 ($0.03 per share) for the same period in 1998.

Capital Resources and Liquidity
- -------------------------------

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

Cash Flows and Liquidity.  At July 31, 1999, Alliance has current assets of
- ------------------------
$5.632 million and current liabilities of $8.280 million, which resulted in a
net current deficit of $2.648 million.  Since April 30, 1999, the net current
deficit has decreased from $5.621 million.  The $2.973 million decrease is
primarily due to additional borrowings of $5.00 million made on July 30, 1999.
Current liabilities at July 31, 1999 increased to $8.28 million compared to
$8.072 million at April 30, 1999.

For the quarter ended July 31, 1999, net cash provided by the Company's
operating activities was $.489 million compared to cash used of $.889 million
for the quarter ended July 31, 1998.   This was caused primarily by significant
payments of vendor payables in the quarter ended July 31, 1998.

                                       9
<PAGE>

Investing activities of the Company used $5.302 million in net cash flow for the
quarter ended July 31, 1999 compared to $.757 million used for the quarter ended
July 31, 1998.  The increase was principally due to property expenditures of
$5.004 million more than the 1998 period as a result of the U.K. property
development program.

Financing activities provided $8.815 million for the quarter ended July 31, 1999
compared to $1.500 million for the quarter ended July 31, 1998, as a result of
additional borrowings related to the U.K. property development program.

Overall, cash and cash equivalents increased by $4.003 million in the quarter
ended July 31, 1999 compared to an decrease of $.146 million in the 1998 period
as a result of the additional borrowings.

Capital Expenditures.  Currently, there are no material long-term commitments
- --------------------
associated with the Company's U.S. capital expenditure plans.  Consequently, the
Company has a significant degree of flexibility to adjust the level of such
expenditures as circumstances warrant.  The Company primarily uses internally
generated cash flow and proceeds from the sale of oil and gas properties to fund
U.S. capital expenditures, other than significant acquisitions, and to fund its
working capital deficit.  If the Company's internally generated cash flows
should be insufficient to meet its banking or other obligations, the Company may
reduce the level of discretionary U.S. capital expenditures or increase the sale
of non-strategic oil and gas properties in order to meet such obligations.

The timing of the Company's U.K. capital expenditures is determined annually by
a budget prepared by the operator of the U.K. properties and approved by
Alliance.  Currently, there are material commitments for the 2000 fiscal year.
Management believes that these commitments will be met by funds available under
the Company's credit facility and internally generated cash flow.  The level of
the Company's capital expenditures will vary in future periods depending on
energy market conditions and other related economic factors. (This is a forward-
looking statement; refer to the Cautionary Statement Regarding Forward Looking
Statements).

Financing Arrangements.  The Company was not in compliance with certain
- ----------------------
covenants of its loan agreements, which included but were not limited to the
maintenance of minimum levels of working capital and interest coverage.  Prior
to these violations causing an event of default, which would have resulted in an
acceleration of the repayment of the loans, the Company obtained waivers from
the lenders for all covenant violations.  Effective July 30, 1999 the loan
agreement was amended to revise the borrowing limit.  This enabled the Company
to borrow an additional $5,000,000 as of July 30, 1999.  The due date of the
Tranche B portion of the loan was extended from January 31, 2001 to July 31,
2001.  In addition, the date of the borrowing base and collateral value
redetermination scheduled to occur on July 31, 1999 was deferred until December
31, 1999.

Financial Condition. The accompanying financial statements have been prepared on
- -------------------
a going concern basis, which contemplates the realization of assets and
satisfaction of liabilities in the normal course of business. The Company
continues to incur losses, continues to experience working capital deficits and
is obliged to commence repayments on the borrowings on October 30, 2000.  These
factors among others may indicate the Company will be unable to continue as a
going concern for a reasonable period of time.

                                       10
<PAGE>

The financial statements do not include any adjustments relating to the
recoverability and classification of liabilities that might be necessary should
the Company be unable to continue as a going concern.  Despite its negative cash
flow, the Company has been able to secure financing to support its operations to
date.  The Company has reached agreement with its principal bank to amend
certain provisions of the loan agreement to allow for additional borrowing
capacity, to defer the borrowing base redetermination date from July 31, 1999 to
December 31, 1999, and extend the repayment due date of the Tranche B portion of
the loan to July 31, 2001.  The amendment does not, however, change the other
scheduled repayment dates which commences on October 30, 2000.

The Company's continuation as a going concern is dependent upon its ability to
generate sufficient cash flow to meet is obligations on a timely basis, to
continue to comply with the terms of its borrowing agreements, to obtain
additional financing or refinancing as will be required and ultimately to attain
profitability.  Management believes it has a business plan that, if successfully
executed, will achieve these objectives. (This is a forward-looking statement;
refer to the Cautionary Statement Regarding Forward Looking Statements).

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

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

Prices obtained for oil and gas production depend upon numerous factors that are
beyond the control of the Company including the extent of domestic and foreign
production, imports of foreign oil, market demand, domestic and world-wide
economic and political conditions, and government regulations and tax laws.
Prices for oil and gas received by the Company have fluctuated significantly in
recent years, as noted in the following table.

<TABLE>

</TABLE>

During February 1999, the Company completed a transaction to hedge approximately
65% of its existing monthly gas production by installing a floor of $1.60/MMBTU
and a cap of $2.07/MMBTU.  This will protect the Company from any severe
declines in natural gas prices until October 31, 1999, and conversely limit the
benefit of prices in excess of the cap.  During April 1999, the Company
completed a transaction to hedge approximately 40% of its existing monthly oil
production by installing a floor of $12.00/barrel.  This will protect the
Company from any severe declines in oil prices until October 31, 1999.

ISSUES RELATED TO THE YEAR 2000
- -------------------------------

General.  The following Year 2000 statements constitute a Year 2000 Readiness
- --------
Disclosure within the meaning of the Year 2000 Information and Readiness
Disclosure Act of 1998. The Year 2000 problem has arisen because many existing
computer programs use only the last two digits to refer to a year. Therefore,
these computer programs do not properly recognize and process date-sensitive
information beyond 1999. In general, there are two areas where Year 2000
problems may exist for the Company: information technology such as computers,
programs and related systems ("IT") and non-information technology systems such
as embedded technology on a silicon chip ("Non IT").

The Plan.  Alliance's Year 2000 Plan (the "Plan") has four phases: (i)
- --------
assessment, (ii) inventory, (iii) remediation, testing and implementation and
(iv) contingency plans. Approximately twelve months ago, the Company began its
phase one assessment of its particular exposure to problems that might arise as
a result of the new millennium. The assessment and inventory phases have been
substantially completed and have identified Alliance's IT systems that must be
updated or replaced in order to be Year 2000 compliant. Remediation, testing and
implementation are scheduled to be completed by September 30, 1999, and the
contingency plan phase of the Plan is scheduled to be completed by October 31,
1999.  Alliance's assessment of the readiness of third parties whose IT systems
might have an impact on Alliance's business has thus far not indicated any
material problems.

With regard to Alliance's Non IT systems, the Company believes that most of
these systems can be brought into compliance on schedule. Alliance's assessment
of third party readiness is not yet completed. Because the potential problem
with Non IT systems involves embedded chips, it is difficult to determine with
complete accuracy where all such systems are located. As part of its Plan, the
Company is making formal and informal inquiries of its vendors, customers and
transporters in an effort to determine the third party systems that might have
embedded technology requiring remediation.

Estimated Costs.  Although it is difficult to estimate the total costs of
- ---------------
implementing the Plan through January 1, 2000 and beyond, Alliance's preliminary
estimate is that such costs will not be material. To date, the Company has
determined that its IT systems are either compliant or can be made compliant for
less than $50,000. However, although management believes that its estimates are
reasonable, there can be no assurance, for the reasons stated in the next
paragraph, that the actual cost of implementing the Plan would not differ
materially from the estimated costs.

Potential Risks.  The failure to correct a material Year 2000 problem could
- ----------------
result in an interruption in, or a failure of, certain normal business
activities or operations. This risk exists both as to Alliance's IT and Non IT
systems, as well as to the systems of third parties. Such failures could
materially and adversely affect Alliance's results of operations, cash flow and
financial condition. Due to the general uncertainty inherent in the Year 2000
problem, resulting in part from the uncertainty of the Year 2000 readiness of
third party suppliers, vendors and transporters, the Company is unable to
determine at this time whether the consequences of Year 2000 failures will have
a material impact on Alliance's results of operations, cash flow or financial
condition. Although the Company is not currently able to determine the
consequences of Year 2000 failures, its current assessment is that its area of
greatest potential risk in its third party relationships is in connection with
the transporting and marketing of the oil and gas

                                       12
<PAGE>

produced by the Company. The Company is contacting the various purchasers and
pipelines with which it regularly does business to determine their state of
readiness for the Year 2000. Although the purchasers and pipelines will not
guaranty their state of readiness, the responses received to date have indicated
no material problems. The Company believes that in a worst case scenario, the
failure of its purchasers and transporters to conduct business in a normal
fashion could have a material adverse effect on cash flow for a period of six to
nine months. Alliance's Year 2000 Plan is expected to significantly reduce
Alliance's level of uncertainty about the compliance and readiness of these
material third parties. The evaluation of third party readiness will be followed
by Alliance's development of contingency plans.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
- ---------------------------------------------------------

In addition, the dates for completion of the phases of the Year 2000 Plan are
based on Alliance's best estimates, which were derived using numerous
assumptions of future events. Due to the general uncertainty inherent in the
Year 2000 problem, resulting in part from the uncertainty of the Year 2000
readiness of third-parties and the interconnection of computer systems, the
Company cannot ensure its ability to timely and cost-effectively resolve
problems associated with the Year 2000 issue that may affect its operations and
business. Accordingly, shareholders and potential investors are cautioned that
certain events or circumstances could cause actual results to differ materially
from those projected, estimated or predicted.

Item 3.  Quantitative and Qualitative Analysis on Market Risk

The Company's primary market risks relate to changes in interest rates and in
the prices received from sales of oil and natural gas.  The Company's primary
risk management strategy is to partially mitigate the risk of adverse changes in
its cash flows caused by increases in interest rates on its variable rate debt,
and decreases in oil and natural gas prices, by entering into derivative
financial and commodity instruments, including swaps, collars and participating
commodity hedges.  By hedging only a portion of its market risk exposures, the
Company is able to participate in the increased earnings and cash flows
associated with decreases in interest rates and increases in oil and natural gas
prices; however, it is exposed to risk on the unhedged portion of its variable
rate debt and oil and natural gas production.

Historically, the Company has attempted to hedge the exposure related to its
variable rate debt and its forecasted oil and natural gas production in amounts
which it believes are prudent based on the prices of available derivatives and,
in the case of production hedges, the Company's deliverable volumes.  The
Company attempts to manage the exposure to adverse changes in the fair value of
its fixed rate debt agreements by issuing fixed rate debt only when business
conditions and market conditions are favorable.

The Company does not use or hold derivative instruments for trading purposes nor
does it use derivative instruments with leveraged features.  The Company's
derivative instruments are designated and effective as hedges against its
identified risks, and do not of themselves expose the Company to market risk
because any adverse change in the cash flows associated with the derivative
instrument is accompanied by an offsetting change in the cash flows of the
hedged transaction.

Personnel who have appropriate skills, experience and supervision carry out all
derivative activity.  The personnel involved in derivative activity must follow
prescribed trading limits and

                                       13
<PAGE>

parameters that are regularly reviewed by senior management. The Company uses
only well-known, conventional derivative instruments and attempts to manage its
credit risk by entering into financial contracts with reputable financial
institutions.

Following are disclosures regarding the Company's market risk sensitive
instruments by major category.  Investors and other users are cautioned to avoid
simplistic use of these disclosures.  Users should realize that the actual
impact of future interest rate and commodity price movements will likely differ
from the amounts disclosed below due to ongoing changes in risk exposure levels
and concurrent adjustments to hedging positions.  It is not possible to
accurately predict future movements in interest rates and oil and natural gas
prices.

Interest Rate Risks (non-trading). the Company uses both fixed and variable rate
- ---------------------------------
debts to partially finance operations and capital expenditures.  As of July 31,
1999, the Company's debt consists of $48,389,521 in borrowings under its Credit
Agreement which bear interest at a variable rate, and $10,499,684 in borrowings
under its 10% Senior Subordinated Notes which bear interest at a fixed rate.
The Company hedges a portion of the risk associated with its variable rate debt
through derivative instruments which consist of interest rate swaps and collars.
Under the swap contracts, the Company makes interest payments on its Credit
Agreement as scheduled and receives or makes payments based on the differential
between the fixed rate of the swap and a floating rate plus a defined
differential. These instruments reduce the Company's exposure to increases in
interest rates on the hedged portion of its debt by enabling it to effectively
pay a fixed rate of interest or a rate, which only fluctuates within a
predetermined ceiling and floor.  A hypothetical increase in interest rates of
two percentage points would cause a loss in income and cash flows of $725,000
during the current fiscal year, assuming that outstanding borrowings under the
Credit Agreement remain at current levels.  This loss in income and cash flows
would not be offset by any increase in income and cash flows associated with the
interest rate swap and collar agreements that are in effect for the current
fiscal year.  A hypothetical decrease in interest rates of two percentage points
would cause an increase in the fair value of $0 in the Company's Senior
Subordinated Notes from their fair value at July 31, 1999.

Commodity Price Risk (non trading).  The Company hedges a portion of the price
- -----------------------------------
risk associated with the sale of its oil and natural gas production through the
use of derivative commodity instruments, which consist of collars and
participating hedges.  These instruments reduce the Company's exposure to
decreases in oil and natural gas prices on the hedged portion of its production
by enabling it to effectively receive a fixed price on its oil and natural gas
sales or a price that only fluctuates between a predetermined floor and ceiling.
As of August 1, 1999, the Company had entered into derivative commodity hedges
covering an aggregate of 30,000 barrels of oil and 240,000 MMbtu's of gas that
extend through October 1999.  Under these contracts, the Company sells its oil
and natural gas production at spot market prices and receives or makes payments
based on the differential between the contract price and a floating price which
is based on spot market indices.  The amount received or paid upon settlement of
these contracts is recognized as oil or natural gas revenues at the time the
hedged volumes are sold.  A hypothetical decrease in oil and natural gas prices
of 10% from the price in effect as of July 31, 1999, would cause a loss in
income and cash flows of $342,992 during 1999, assuming that oil and gas
production remain at current levels.  This loss in income and cash flows would
not be offset by any increase in income and cash flows associated with the oil
and natural gas derivative contracts that are in effect.

                                     ------

This  report  contains  certain  forward-looking  statements,  as defined in the
Private Securities Litigation Reform Act of 1995, including, without limitation,
all  statements  regarding the Company's  expected  future  financial  position,
results of operations,  business strategy, plans or objectives of management and
the potential for future  transactions  to be  completed.  Such forward  looking
statements   include   statements   containing   words   such   as   "believes,"
"anticipates,"  "estimates,"  "expects,"  "may" and words of similar import,  or
statements  of  management's  opinion.  Although the Company  believes  that the
expectations   reflected  in  such  forward  looking  statements  are  based  on
reasonable  assumptions,  no assurance can by given that such  expectations will
prove to have been correct,  and actual results may differ materially from those
described  or implied in such  forward  looking  statements.  Factors that could
cause the Company's actual results to differ from the expectations  reflected in
forward-looking  statements  include  the risks of  operating  in a  competitive
environment, the market for the Company's products, the market for the Company's
properties,  and changes in interest and inflation rates. Moreover,  whether any
anticipated   future  transaction  occurs  is  subject  to  numerous  risks  and
uncertainties,  many  of  which  are  outside  our  control.  For  example,  the
successful  completion of a  transaction  will be subject to  negotiations  with
third  parties  who may not accept  terms that are  acceptable  to the  Company.
Similarly,  whether or not we can complete any such transactions may be affected
by changes in market  conditions  or the  financial  and business  conditions of
third parties and other events outside the Company's exclusive control.

Item 1. Business
- ----------------

The Company
- -----------

American  Rivers Oil Company (the "Company") was originally  incorporated  under
the  laws  of the  State  of  Colorado  on  February  2,  1981  as  Metro  Cable
Corporation.  On March 31,  1992,  the  Company  reincorporated  in the State of
Wyoming and changed its name to Metro Capital Corporation ("Metro"). In December
1995,  Metro,  upon approval of its  shareholders,  completed a transaction with
Karlton Terry Oil Company and its  affiliates  ("KTOC")  whereby KTOC  exchanged
certain oil and gas  properties  for  7,717,820  shares of newly created Class B
Common Stock which  represented  80% of the then issued and  outstanding  voting
securities of Metro (the  "Transaction"  or the "Metro/KTOC  Transaction").  The
only  class  of  securities  of  Metro  issued  and  outstanding  prior  to  the
Transaction  was Common Stock.  Metro and KTOC  previously  were not affiliated.
Upon completion of the  Transaction,  the Company's name was changed to American
Rivers Oil Company.  Management of KTOC  succeeded to the board of directors and
serve as officers operating the oil and gas properties previously owned by KTOC.
Prior to the  Transaction,  Metro  had been  principally  engaged  in  petroleum
operations, real estate development and seeking business opportunities.

Prior  to  and  in  connection  with  the  Transaction  described  above,  Metro
transferred  to Bishop Capital  Corporation  ("Bishop")  (formerly  Bishop Cable
Communications  Corporation),  a wholly-owned  subsidiary,  all of the Company's
assets except for $700,000 cash and its working interest in an insignificant oil
property.  The assets transferred to Bishop,  together with Bishop's  previously
owned assets,  were operated  autonomously by the prior  management of Metro who
became  officers  and  directors  of Bishop  pursuant  to the terms of  separate
five-year  Operating and Voting  Agreements.  Since the Company did not exercise
control over Bishop's operations,  the investment is accounted for by the equity

                                       2
<PAGE>

method  prior to the  distribution  of the  outstanding  stock of  Bishop to the
Company's  shareholders  in June 1997. The terms of the  Metro/KTOC  Transaction
also  provided  that  the  shares  of  Bishop  owned  by the  Company  would  be
distributed  to the  Company's  common  shareholders  within  36  months  of the
Transaction  date and that the  holders of the  Company's  Class B Common  stock
would not  participate in the  distribution.  On November 8, 1996, the Company's
Board of Directors  authorized a spin-off  distribution of Bishop's Common Stock
as a partial liquidating dividend to the Company's common shareholders of record
on November  18, 1996 on the basis of one share of Bishop  Common Stock for four
shares of the Company's  Common  Stock.  The  distribution  occurred on June 20,
1997.

At March 31, 1999, the Company had two part-time employees.


Operating Strategy
- ------------------

The Company has sold a significant  portion of its producing  properties to meet
its current obligations including maturing indebtedness. The Company's operating
objective is to pursue merger or acquisition  opportunities  with a substantial,
stable company. The Company is currently negotiating with a candidate;  however,
no  definitive  agreement  with  respect to any  acquisition  has been  reached.
Accordingly,  the Company cannot  predict  whether any agreement may be reached,
the timing of the contemplated  transaction or the results of the transaction if
any  agreement is reached.  Even if an agreement is reached,  such a transaction
may not be completed as a result of factors  outside of either party's  control,
such as regulatory  requirements,  the failure to secure any necessary  security
holder vote or changes in market conditions.

Markets
- -------

The three  principal  products  produced and marketed by the Company  during the
last fiscal  year were crude oil,  natural  gas and  natural  gas  liquids.  The
Company does not currently use commodity futures contracts or price swaps in the
marketing  of its natural gas and crude oil.  During the fiscal year the Company
sold all of its  producing  properties  except one well that is shut in awaiting
sale either for salvage  value or as a water  disposal  well to producers in the
area.

Crude oil produced from the  Company's  properties  has  generally  been sold by
truck or pipeline to unaffiliated third-party purchasers at the prevailing field
price (the  "posted  price").  As the Company has sold all of its oil  producing
properties  effective  March,  1999,  there  are no  primary  purchasers  of the
Company's crude oil.

The Company sold its natural gas production at the wellhead to various  pipeline
purchasers  or natural gas  marketing  companies.  The wellhead  contracts  have
various terms and conditions,  including contract duration.  Under each wellhead
contract the purchaser is generally  responsible  for  gathering,  transporting,
processing  and  selling the natural gas and natural gas liquids and the Company
receives a net price at the wellhead. As the Company sold all of its natural gas
producing  properties  in fiscal 1999,  there are no primary  purchasers  of the
Company's natural gas and natural gas liquids.

                                       3
<PAGE>

Competition
- -----------

The Company has sold its producing  properties  to meet its current  obligations
including  eliminating its maturing bank debt.  Consequently,  the Company is no
longer competing with other oil and gas producers.


Operations of Bishop
- --------------------

As  previously  discussed,  Bishop was  operated  autonomously  by the  previous
management of the Company pursuant to the terms of separate five-year  Operating
and Voting  Agreements which terminated upon the distribution of Bishop's Common
Stock on June 20, 1997.


Item 2. Properties
- ------------------

The Company's has one property in Kentucky that produced for one month on a test
basis in fiscal  1999 to  determine  its  economic  viability.  It is  currently
classified  as property  held for sale either as salvage or to a producer in the
area who needs additional water disposal capabilities.

Reserves
- --------

Information  regarding  the  Company's  proved and proved  developed oil and gas
reserves and the  standardized  measure of discounted  future net cash flows and
changes  therein  is not  applicable  as the  Company  does not  have  producing
properties as of year end.

Since  April 1, 1996,  the  Company has not filed any oil or natural gas reserve
estimates or included any such estimates in reports to any Federal  authority or
agency, other than the Securities and Exchange Commission.

Production
- ----------

The following table sets forth information with respect to the Company's oil and
gas production,  average sales prices and average  production  costs for the two
years ended March 31, 1999:

                                                 1999         1998

     (1)  Production  units were  converted to common  units of measure  using a
          conversion  ratio of six Mcf of  natural  gas equals one barrel of oil
          equivalent (BOE).  Production costs exclude depreciation and depletion
          associated with oil and gas properties.

Productive Wells
- ----------------

Company owns no productive wells at March 31, 1999

Developed and Undeveloped Acreage
- ---------------------------------

At March 31, 1999,  the Company does have a negligible  amount of developed  and
undeveloped acreage which is held for sale as discussed in item 2, properties.


Drilling Activity
- -----------------

The Company only participated in the drilling of one gross (.75 net) well in the
past two years. This well was a development well that was drilled in fiscal 1998
and resulted in a dry hole.

Present Activities
- ------------------

The  Company has sold  substantially  all of its  properties  to retire its bank
debt.  Oil and gas prices  have been  extremely  depressed,  and the  Company is
considering  merger  possibilities with other business entities having sustained
cash flow with less price  volatility  relating to its  product.  The  Company's
auditors have qualified their opinion as to the continuation of the Company as a
going  concern.  The financial  statements are prepared on a going concern basis
which  contemplates the realization of assets and the liquidation of liabilities
in the ordinary  course of  business.  The Company is  currently  negotiating  a
merger which is integral to the Company's  ability to continue  operations.  The
success  of this  merger  cannot be  assured.  See Item I,  Business,  Operating
Strategy, above.

Item 3. Legal Proceedings
- -------------------------

The  Company is a party to legal  proceedings.  The suit,  Consult and Assist v.
American Rivers Oil Company and Karlton Terry, (United States District Court for
the District of Colorado,  Case No. 99-K-299) filed February 4, 1999. Plaintiff,
Consult and Assist, a Luxemborg Co, purchased  275,000 shares of common stock of
American  Rivers  Oil  Company on  November  11,  1996 for $1.00 per share.  The
plaintiff  alleges that defendants  made untrue  statements of material fact and
omitted to state certain other facts in connection with plaintiff's  purchase of
common stock.  The plaintiff seeks to recover  $275,000 plus interest,  punitive
damages, attorneys' fees and costs.

Defendants deny the allegations of the Complaint and intend to vigorously defend
against the lawsuit.  Defendants  have filed an Answer to the  Complaint and the
case is currently in the discovery stage.

Item 4. Submission of Matters to a Vote of Security Holders
- -----------------------------------------------------------

No matters were submitted to a vote of the Company's security holders during the
fourth quarter of the fiscal year ended March 31, 1999.

As of March 31,  1999 there were  approximately  2,010  holders of record of the
Company's Common Stock.

Class B Common Stock
- --------------------

The Class B Common Stock,  which is not traded in any public trading market, was
issued in connection with the Transaction described in Item 1 and has all of the
rights of currently issued and outstanding  shares of the Company's Common Stock
except that the Class B Common Stock was not entitled to participate in the June
20,  1997  distribution  of shares of Bishop  Capital  Corporation.  The Class B
Common Stock is  convertible  on a  one-for-one  share basis into the  Company's
Common  Stock.  The Company  plans to  encourage  the holders the Class B Common
shares to convert to Common Stock so that there will only be one class of stock

As of March 31, 1999,  there were 20 holders of record of the Company's  Class B
Common Stock.

Dividends
- ---------

The Company  has paid no cash  dividends  on its Common  Stock or Class B Common
Stock  and does not  intend to pay cash  dividends  in the  foreseeable  future.
Payment of cash  dividends,  if any,  in the future  will be  determined  by the
Company's  Board of  Directors  in light of the  Company's  earnings,  financial
condition and other relevant considerations.

                                       6
<PAGE>

Options
- -------

In connection with the Asset Purchase  Agreement with Bishop referred to in item
1, the Company  agreed to grant a 120 day option to the common  stockholders  to
acquire common shares at $0.10 per share if certain events did not occur. As the
market price of the common during the exercise period was less than the exercise
price,  management elected to forego the administrative cost of distributing the
options to the common shareholders. The option expired in April, 1999.

Item 6. Management's  Discussion and Analysis of Financial Condition and Results
of Operations
- --------------------------------------------------------------------------------

The audited  consolidated  statements of operations  and cash flows for the year
ended March 31, 1998 include the  unconsolidated  operations  of Bishop  Capital
Corporation  using the equity method of accounting  until it was  distributed on
June  20,  1997.  The  following  discussion  and  analysis  should  be  read in
conjunction  with the  Company's  Consolidated  Financial  Statements  and Notes
thereto.

Results of Operations
- ---------------------

The Company's  revenues were $18,000, a decrease of $640,000 for the fiscal year
ended March 31, 1999 from $658,000 in fiscal 1998. The Company had a net loss in
fiscal 1999 of $114,000 as compared to a net loss of $2,950,000 for fiscal 1998.
The 1999  decrease  in the loss arose from the sale of the  Company's  producing
properties  combined with the  curtailment of operations.  As further  described
below, of the Company's $2,950,000 loss in 1998,  $2,567,000 is represented by a
charge for impairment to the Company's proved reserves,  and $95,000  represents
the Company's  equity in the loss incurred by Bishop  Capital  Corporation,  the
Company's  subsidiary that was spun-off on June 20, 1997. All losses incurred by
Bishop  during  1998  were  funded  from  Bishop's  operations  and not from the
Company.  In  fiscal  1999 the  Company  sold  its  interests  in its  producing
properties  in the DJ Basin  and the Ohio  River  property  realizing  a gain of
$293,000.  In fiscal 1998, the Company sold its interest in a producing property
in Louisiana,  the Lake Hatch prospect, and realized a gain of $92,000 Investors
are urged to be cautious in considering the forward-looking statements contained
in this paragraph and elsewhere herein.

Fiscal 1999 Compared to Fiscal 1998

The Company's oil and gas sales  decreased by $637,000 in fiscal 1999 due to the
sale of the  bulk of the  producing  properties  in the  first  quarter  and the
remaining producing properties in the second quarter.

The production costs decreased  $371,000 in fiscal 1999 compared to 1998 because
of the decreased oil and gas production.

General and administrative  expenses increased  approximately  $89,000 in fiscal
1999 compared to 1998.  The  components  of the change  consist of reductions of
$97,000 in officer  compensation,  $112,000 in legal,  accounting and consulting
fees,  $18,000 in other  compensation  and payroll  taxes,  and $10,000 in other
miscellaneous  expenses  combined with an increase in the allowance for doubtful
accounts of $150,000.

                                       7
<PAGE>

In fiscal 1998, the Company conducted a comprehensive  review of its reserves as
a result  of the  unsuccessful  drilling  results  of the  Kentucky  well and in
connection  with the fiscal  year end.  The results of the  reevaluation  of the
Company's  reserves,  on a BOE equivalent basis,  resulted in a 94% reduction of
proved developed and undeveloped  reserves, of which 16% was attributable to the
Lake Hatch  property  sale.  Upon  completion of the  reevaluation,  the Company
recorded an  impairment  loss of $2,567,440 to reflect the fair value of the oil
and gas properties at March 31, 1998. There were no additional impairment losses
as the Company's producing properties were sold in fiscal 1999.

Depletion  decreased by approximately  $288,000 in fiscal 1999 compared to 1998.
The decrease  principally arises because production was lower due to the sale of
the properties early in the fiscal year.

The Company did not incur a loss from its equity  method of  accounting  for the
investment in Bishop Capital  Corporation in 1999 because the Company  completed
the spin off of Bishop on June 20, 1997.

The gain on the sale of oil and gas  properties  increased  by  $229,000  as one
property, the Lake Hatch property in Louisiana,  was sold in 1998 and all of the
DJ Basin properties along with the Ohio River property were sold in fiscal 1999.

Deferred tax benefits  decreased by $232,000  because the Company  exhausted its
deferred tax benefits totaling $232,000 in 1998. The Company has recorded a full
valuation  allowance for its deferred tax assets due to substantial  uncertainty
of realization.

The  production  volumes and average  sales prices for the years ended March 31,
1999 and 1998 were as follows:

                                              1999          1998
                                              ----          ----

            Oil production (Bbls)                269        17,039
            Average sales price (per Bbl)   $   9.08      $  17.05

            Natural gas production (mcf)      13,000       197,864
            Average sales price (per mcf)   $   2.10      $   1.84

Production volumes decreased, 95% for gas and 98% for oil. Average prices of gas
increased and oil  declined.  The average sales price of crude oil decreased 47%
per barrel and gas increased 14% per MCF.


Financial Condition
- -------------------

At March 31, 1999, the Company's  working capital  deficit  amounted to $16,000.
The Company is engaged in negotiations  relative to a possible merger or similar
transaction. With no significant operations or producing assets, completion of a
business  combination  or similar  transaction  is  essential  to the  Company's
ability to continue operations.  These negotiations  however, are preliminary in
nature and we can provide no assurance that they will be successful.

The following summary table reflects  comparative cash flows for the Company for
the two years ended March 31, 1999:

                                                     1999         1998
                                                     ----         ----

      Net cash used in operating activities       $(330,000)   $(229,000)
      Net cash provided by investing activities     334,000      335,000
      Net cash used in financing activities          (1,000)    (243,000)

Net cash used in  operating  activities  increased  in fiscal  1999  compared to
fiscal 1998 due to decreased  costs and expenses  associated  with operating the
Company as it became  inactive  operationally.  However,  cash was  utilized  to
reduce payables  incurred in 1998 for operating  activities which resulted in an
increase in cash utilized in operating activities

Net cash provided by investing activities of $330,000 in fiscal 1999 principally
resulted  from the  sale of the DJ  Basin  and  Ohio  River  properties,  net of
proceeds used to retire existing debt.

Impact of Inflation

The Company  cannot  determine the precise  effects of inflation.  However,  the
impact of general price  inflation has not had a material  adverse effect on the
results of the Company's operations.

Year 2000 Issues

"Year 2000  problems"  result  primarily  from the  inability  of some  computer
software to properly  store,  recall or use data after December 31, 1999.  These
problems may affect many  computers  and other  devices  that  contain  imbedded
computer chips. The Company's  operations,  however,  do not rely extensively on
information  technology ("IT") systems. The IT software and hardware systems the
Company  operates  are all  publicly  available,  pre-packaged  systems that are
readily replaceable with other functionally  similar systems.  Accordingly,  the
Company  does not  believe  that it will be  materially  affected  by Year  2000
problems in its IT software and hardware systems.

The Company  relies on non-IT  systems  that may suffer from Year 2000  problems
including  telephone systems and facsimile and other office machines.  Moreover,
the Company relies on third-parties that may suffer from Year 2000 problems that
could affect the Company's operations,  including banks, and utilities. In light
of the Company's substantially reduced operations,  the Company does not believe
that such  non-IT  systems or  third-party  Year 2000  problems  will affect the
Company in a manner that is different  or more  substantial  than such  problems
affect other similarly situated companies generally.  Consequently,  the Company
does not  currently  intend  to  conduct  a  readiness  assessment  of Year 2000
problems  or to develop a detailed  contingency  plan with  respect to Year 2000
problems that may affect the Company's IT and non-IT systems or third-parties.

The foregoing is a "Year 2000  Readiness  Disclosure"  within the meaning of the
Year 2000 Information and Readiness Disclosure Act of 1998.

         Name                  Age                 Office
         ----                  ---                 ------

     Karlton Terry             45           Chairman of the Board, President and
                                            Chief Executive Officer

     Denis Bell                64           Director


     Karlton  Terry.  Mr. Terry is a graduate of the University of Colorado with
postgraduate work at Brown University and has 17 years experience in the oil and
gas business. He began his career as a landman for Samuel Gary Oil Producer, and
formed and was president of Leed Petroleum  Corporation,  which was subsequently
sold to Burma  Oil of  England.  After  the sale of Leed,  he was  president  of
Karlton Terry Oil Company for twelve years.

     Denis Bell.  Mr. Bell is executive  chairman and a founding  shareholder of
Rackwood Mineral  Holdings PLC, a coal producing  company in the United Kingdom.
He was  appointed  a director  of  Rackwood  Mineral  Holding  PLC in 1993.  His
experience in mining,  particularly open cast mining,  commenced in 1968 when he
established his own company to operate a number of open cast sites and two small
underground  mines.  This  company  was sold to  Mining  Investment  Corporation
Limited,  where he  remained  a  director  until  1979.  Since  then he has been
involved as an  Executive  Director  of a number of private  and public  mineral
companies,  including NSM PLC (from which he resigned in 1989), Anglo United PLC
(from which he resigned in 1991) and Denis Bell Inc. and its  subsidiaries.  Mr.
Bell,  through  Haddon,  Inc.,  of which he owns  100%,  has  owned  oil and gas
properties in the United States since 1983.

The  directors  of the Company are elected to hold office  until the next annual
meeting of  shareholders  or until a successor  has been elected and  qualified.
Officers of the Company are elected  annually by the Board of Directors and hold
office until their successors are duly elected and qualified.

                                       10

No arrangement or understanding exists between any of the above officers and
directors pursuant to which any one of those persons were selected to such
office or position. None of the directors hold directorships in other companies
except as noted above.

     b. Identification of Certain Significant Employees

     Not applicable

     c. Family Relationships

     Not applicable

     d. Involvement in Certain Legal Proceedings

     Not applicable

     e. Compliance with Section 16(a) of the Securities Exchange Act of 1934

     Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
executive  officers  and  directors,  and  persons  who own more than 10% of the
outstanding Common Stock of the Company to file reports of ownership and changes
in ownership  with the SEC and Nasdaq.  Based solely on its review of the copies
of  such  reports  received  by it,  or  written  representations  from  certain
reporting  persons that no Forms 5 were required for those persons,  the Company
believes that during fiscal 1999, its executive officers,  directors and greater
than ten percent stockholders complied with all applicable filing requirements.

                 AMERICAN RIVERS OIL COMPANY AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)


1.   Basis of Presentation

In the opinion of management, all adjustments, consisting of normal recurring
accruals, have been made which are necessary for a fair presentation of the
financial position of the Company at June 30, 1999 and the results of operations
and cash flows for the three months ended June 30 1999 and 1998. Quarterly
results are not necessarily indicative of expected annual results. For a more
complete understanding of the Company's operations and financial position,
reference is made to the consolidated financial statements of the Company, and
related notes thereto, filed with the Company's annual report on Form 10-KSB for
the year ended March 31, 1999, previously filed with the Securities and Exchange
Commission.

Certain reclassifications have been made to the 1998 financial statements to
conform to the presentation in 1999. The reclassifications had no effect on the
1998 results of operations.

2.   Sale of Oil and Gas Properties -1998

On June 4, 1998, Company entered into an agreement to sell the Company's
Colorado oil and gas properties with an effective date of March 1, 1998, in
order to provide liquidity and to repay short-term bank debt. The Company
realized proceeds from the disposition of these properties in the amount of
$900,327. The proceeds were used as follows:

           Bank debt                                   $ 540,000
           Payables to related parties                    42,894
           Advances to affiliates                        150,000
           Accounts payable and working capital          167,434
                                                         -------
                                                         900,327

3.   Net Loss Per Share

The computation of net loss per share is based on the rights of each class of
common stock. Each class was allocated its pro rata percentage of the
consolidated net income (loss) based on the ratio of common shares outstanding
to total common and Class B shares outstanding.

4.   Subsequent Event - Note Payable

On July 7,1999, the Company executed a promissory not to a bank in the amount of
$75,000.00, due December 1, 1999, bearing interest at 1% over Wall Street
Journal prime. The proceeds from the note were used to fund current trade
obligations and provide working capital. The Company's president, Karlton Terry,
also executed the note as a comaker.

                 AMERICAN RIVERS OIL COMPANY AND SUBSIDIARIES
                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


The following discussion and analysis should be read in conjunction with the
Company's unaudited consolidated financial statements and notes thereto.

Forward-Looking Statements

The Company believes that this report contains certain forward-looking
statements, as defined in the Private Securities Litigation Reform Act of 1995,
including, without limitation, statements containing the words "believes,"
"anticipates," "estimates," "expects," "may" and words of similar import, or
statements of management's opinion. Such forward-looking statements involve
known and unknown risks, uncertainties and other factors which may cause the
actual results, performance or achievements of the Company to be materially
different from any future results, performance or achievements expressed or
implied by such forward-looking statements.

Results of Operations

Three Months Ended June 30, 1999 Compared to 1998

The Company's oil and gas sales revenue decreased by $19,000 or 100% in the
quarter ended June 30, 1999 compared to the corresponding quarter in 1998. The
primary factor in the decrease is attributed to the sale of the properties
referred to in note 2 to the financial statements.

The production volumes and average sales prices during the periods were as
follows:

<TABLE>

                                                    Three Months Ended

                                                    ------------------
                                                    1999          1998

<S>                                               <C>          <C>
     Oil production (barrels)                        - 0 -          145
     Average sales price per barrel                $   n/a      $ 11.50

     Natural gas production (mcf)                    - 0 -        8,422
     Average sales price per mcf                   $   n/a      $  2.10

</TABLE>

Oil and gas production costs decreased by $21,000 compared to the corresponding
quarter ended June 30, 1998 because certain producing properties were sold in
1998 (see note 2 to the financial statements). The BOE basis (BOE means barrel
of oil equivalent, using a conversion ratio of six mcf of natural gas to one
barrel of oil), of comparing production costs per BOE were not applicable for
the quarter ended June 30, 1999 and were $13.59 for the comparable quarter of
1998.

General and administrative expenses decreased by $53,000 or 64% for the quarter
ended June 30, 1999 compared to the corresponding quarter in 1998 and is due
primarily to decreases in corporate overhead.

Depreciation, depletion and amortization expense decreased by $10,600, 100% in
the current quarter compared to the corresponding quarter in 1998 due to the
sale of the producing properties referred to in note 2.

Interest expense decreased by $10,000 or 100% for the current quarter of 1999
over the corresponding quarter of 1998 due to a repayment of debt in 1998.

FINANCIAL CONDITION

At June 30, 1999, the Company had a working capital deficiency of $46,000.

The following summary table reflects the Company's cash flows for the nine
months ended June 30, 1999, and 1998:

Net cash used in operating activities                   $(2,900)  $(317,000)
Net cash provided by (used in) investing activities     $     0   $ 900,000
Net cash provided (used in) by financing activities     $     0   $(540,000)

</TABLE>

Net cash used in operating activities decreased $314,000 for the three months
ended June 30, 1999 compared to the three months ended June 30, 1998 is due
primarily to a decrease in operating activities. The Company utilized the
proceeds from the sale of certain properties in 1998 to repay its bank
obligations and currently has no significant operations which accounts for the
changes in investing and financing activities

Operating Strategy

In the fiscal year ended March 31, 1999, the Company has sold a significant
portion of its producing properties to meet its current obligations including
its then maturing indebtedness. The Company's operating objective is to increase
value through pursuing merger or acquisition opportunities with another company.
The Company is currently negotiating with a candidate. The Company cannot
predict whether any agreement may be reached if they are, the timing of the
contemplated transaction or the results of the transaction if any agreement is
reached

In view of the Company's lack of liquidity, if the contemplated merger does not
take place, the Company's value and future potential could be considerably
diminished.

General

Many of the factors which may affect the Company's future operating performance
and long-term liquidity are beyond the Company's control, including, but not
limited to, oil and natural gas prices, the availability and attractiveness of
properties for acquisition, the adequacy and attractiveness of financing and
operational results. The Company is examining alternative sources of long-term
capital, including bank borrowing, the issuance of debt instruments and the sale
of equity securities of the Company. Availability of these sources of capital
and, therefore, the Company's ability to execute its operating strategy will
depend upon a number of factors, some of which are beyond the control of the
Company.

Year 2000 Issues

"Year 2000 problems" result primarily from the inability of some computer
software to property store, recall or use data after December 31, 1999. These
problems may affect may computers and other devices that contain "embedded"
computer chips. The Company's operations, however, do not rely extensively on
information technology ("IT") systems. The IT software and hardware systems the
Company operates are all publicly available, pre-packaged systems that are
readily replaceable with other functionally similar systems. Accordingly, the
Company does not believe that it will be materially affected by Year 2000
problems in its IT software and hardware systems.

The Company relies on non-IT systems that may suffer from Year 2000 problems
including telephone systems and facsimile and other office machines. Moreover,
the Company relies on third parties that may suffer from Year 2000 problems that
could affect the Company's operations, including banks and utilities. In light
of the Company's substantially reduced operations, the Company does not believe
that such non-IT systems or third-party Year 2000 problems will affect the
Company in a manner that is different or more substantial than such problems
affect other similarly situated companies generally. Consequently, the Company

                                       7
<PAGE>

does not currently intend to conduct a readiness assessment of Year 2000
problems or to develop a detailed contingency plan with respect to Year 2000
problems that may affect the Company's IT and non-IT systems or third-parties.

The foregoing is a "Year 2000 Readiness Disclosure" within the meaning of the
Year 2000 Information and Readiness Disclosure Act of 1998.

                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

     (a) The Certificate of Incorporation of the Registrant provides that each
person who was or is made a party or is threatened to be made a party or is
involved in any threatened, pending or completed action, suit or proceeding,
whether formal or informal, whether of a civil, criminal, administrative or
investigative nature (hereinafter a "proceeding"), by reason of the fact that he
or she, or a person of whom he or she is the legal representative, is or was a
director or officer of the Registrant, whether the basis of such proceeding is
an alleged action or inaction in an official capacity or in any other capacity
while serving as a director or officer, shall be indemnified and held harmless
by the Registrant to the fullest extent permissible under Delaware law, as the
same exists or may hereafter exist in the future (but, in the case of any future
change, only to the extent that such change permits the Registrant to provide
broader indemnification rights than the law permitted prior to such change),
against all costs, charges, expenses, liabilities and losses (including, without
limitation, attorneys' fees, judgments, fines, ERISA excise taxes, or penalties
and amounts paid or to be paid in settlement) reasonably incurred or suffered by
such person in connection therewith and such indemnification shall continue as
to a person who has ceased to be a director or officer and shall inure to the
benefit of his or her heirs, executors and administrators.

     (b) The Registrant shall pay expenses actually incurred by a director or
officer in connection with any proceeding in advance of its final disposition;
provided, however, that if Delaware law then requires, the payment of such
- --------  -------
expenses incurred in advance of the final disposition of a proceeding shall be
made only upon delivery to the Registrant of an undertaking, by or on behalf of
such director or officer, to repay all amounts so advanced if it shall
ultimately  be determined that such director or officer is not entitled to be
indemnified.

     (c) The Registrant has also adopted provisions in its Articles of
Incorporation that limit the liability of its directors and officers.  Under the
Articles of Incorporation, and as permitted by the laws of the State of
Delaware, a director is not liable to the Registrant or its stockholders for
monetary damages for breach of fiduciary duty, except for liability for (i) any
breach of the director's duty of loyalty to the Registrant or its stockholders;
(ii) acts or omissions which involve intentional misconduct or a knowing
violation of the law; (iii) the payment of any unlawful dividend, stock purchase
or redemption; or (iv) any transaction from which the director derived any
improper personal benefit.

ITEM 22.  Undertakings

     (1) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (2) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulations S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

     (3) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

     (4) The registrant undertakes that every prospectus (a) that is filed
pursuant to paragraph 3 immediately preceding, or (b) that purports to meet the
requirements of section 10(a)(3) of the Securities Act of 1933 and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new

                                      II-3
<PAGE>

registration statement relating to the securities offered therein, and the
offering of such securities at the time shall be deemed to be the initial bona
fide offering thereof.

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

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

     (7) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

                                    TO THE
                         CERTIFICATE OF INCORPORATION
                        OF AMERICAN RIVERS OIL COMPANY


     American Rivers Oil Company, a corporation organized and existing under and
by virtue of the General Corporation Law of the State of Delaware (the
"Corporation"), does hereby certify:

     FIRST: That the Board of Directors of the Corporation duly adopted
resolutions proposing and declaring advisable the following amendment to the
Certificate of Incorporation of the Corporation:

     Article V shall be revised to read in its entirety as follows:

                                   ARTICLE V

          SECTION 1.  The total number of shares of all classes of stock that
     the Corporation shall have authority to issue is 200,000,000 shares,
     consisting of 180,000,000 shares of common stock, par value $0.001 per
     share ("Common Stock"), 10,000,000 shares of preferred stock, par value
     $0.001 per share ("Preferred Stock"), and 10,000,000 shares of convertible
     restricted voting stock, par value $0.001 per share ("CRV Stock").

          SECTION 2.  Each share of Common Stock of the Corporation shall have
     identical privileges in every respect.  Each holder of Common Stock shall
     be entitled to one vote for each share of Common Stock held of record on
     all matters on which stockholders generally are entitled to vote.  Subject
     to the provisions of law and the rights of the Preferred Stock or any class
     or series of Preferred Stock, dividends may be paid on the Common Stock out
     of assets legally available for dividends, but only at such times and in
     such amounts as the Board of Directors shall determine and declare.  Upon
     the dissolution, liquidation or winding up of the Corporation, after any
     preferential amounts to be distributed to the holders of the Preferred
     Stock or any class or series of Preferred Stock have been paid or declared
     and set apart for payment, the holders of the Common Stock shall be
     entitled to receive all the remaining assets of the Corporation available
     for distribution to its stockholders ratably in proportion to the number of
     shares held by them, respectively.

          SECTION 3.  The Board of Directors is hereby expressly authorized, by
     resolution or resolutions from time to time adopted, to provide, out of the
     unissued shares of Preferred Stock, for the issuance of the Preferred Stock
     in one or more classes or series.  Before any shares of any such class or
     series are issued, the Board of Directors shall fix and state, and hereby
     is expressly empowered to fix, by resolution or resolutions, the
     designations, preferences, and relative, participating, optional or other
     special rights of the shares of each such series, and the qualifications,
     limitations or restrictions thereon, including, but not limited to,
     determination of any of the following:

          (a)  the stated value thereof if different from the par value thereof;

          (b)  whether the shares of such class or series shall have voting
          rights, in addition to any voting rights provided by law, and, if so,
          the terms of such voting rights, which may be full, special or
          limited, and whether the shares of such class or series shall be
          entitled to vote as

          more other classes or series of stock;

          (c)  the dividends, if any, payable on such class or series, whether
          any such dividends shall be cumulative, and, if so, from what dates,
          the conditions and dates upon which such dividends shall be payable,
          the preference or relation that such dividends shall bear to the
          dividends payable on any shares of stock of any other class or any
          other series of the same class;

          (d)  whether the shares of such class or series shall be subject to
          redemption by the Corporation at its option or at the option of the
          holders of such shares or upon the happening of a specified event,
          and, if so, the times, prices and other terms, conditions and manner
          of such redemption;

          (e)  the preferences, if any, and the amount or amounts payable upon
          shares of such series upon, and the rights of the holders of such
          class or series in, the voluntary or involuntary liquidation,
          dissolution or winding up, or upon any distribution of the assets, of
          the Corporation;

          (f)  whether the shares of such class or series shall be subject to
          the operation of a retirement or sinking fund and, if so, the extent
          to and manner in which any such retirement or sinking fund shall be
          applied to the purchase or redemption of the shares of such class or
          series for retirement or other corporate purposes and the terms and
          provisions relative to the operation thereof;

          (g)  whether the shares of such class or series shall be convertible
          into, or exchangeable for, at the option of either the holder or the
          Corporation or upon the happening of a specified event, shares of
          stock of any other class or any other series of the same class or any
          other class or classes of securities or property and, if so, the price
          or prices or the rate or rates of conversion or exchange and the

          (h)  the limitations and restrictions, if any, to be effective while
          any shares of such class or series are outstanding, upon the payment

          (j)  any other powers, preferences and relative, participating,
          optional and other special rights, and any qualifications, limitations
          and restrictions thereof.

          The powers, preferences and relative, participating, optional and
     other special rights of each class or series of Preferred Stock, and the
     qualifications, limitations and restrictions thereof, if any, may differ
     from those of any and all other classes or series at any time outstanding.
     All shares of any one series of Preferred Stock shall be identical in all
     respects with all other shares of such series,

                                       2
<PAGE>

     except that shares of any one series issued at different times may differ
     as to the dates from which dividends thereof shall be cumulative. The Board
     of Directors may increase the number of shares of the Preferred Stock
     designated for any existing class or series by a resolution adding to such
     class or series authorized and unissued shares of the Preferred Stock not
     designated for any other class or series. The Board of Directors may
     decrease the number of shares of Preferred Stock designated for any
     existing class or series by a resolution subtracting from such class or
     series unissued shares of the Preferred Stock designated for such class or
     series, and the shares so subtracted shall become authorized, unissued, and
     undesignated shares of the Preferred Stock.

          SECTION 4.  Each share of CRV Stock of the Corporation shall have
     identical privileges in every respect, as follows:

          (a)  Voting Rights.  Every holder of CRV Stock shall have one-half
          vote for every share of CRV Stock of which he or she is the registered
          holder. The holders of the CRV Stock shall be entitled to vote on all
          matters on which the holders of Common Stock are entitled to vote and
          the CRV Stock shall be considered the same class as Common Stock for
          such purposes.

          (b)  Right to Designate Director.  The holders of the CRV Stock shall
          be entitled at any one time to designate one additional member of the
          board of directors of the Corporation for one term as a director,
          which member shall be subject to the approval (not to be unreasonably
          withheld) of the then existing board of directors of the Corporation.
          Such member shall thereafter be subject to reelection by the holders
          of all of the shares of the Corporation entitled to vote in the
          election of directors.

          (c)  Transfer.  The CRV Stock shall only be transferable with the
          consent of the Board of Directors of the Corporation, such consent not
          to be unreasonably withheld.

          (d)  Conversion.

                    (1)  Until all shares of CRV Stock shall have been
                    converted, on the occurrence of each Sustained Production
                    Level or Reserves Value (as applicable), the number of
                    shares of CRV Stock that is equal to one-half the Applicable
                    Number of Common Shares (as defined below) shall be
                    converted into the Applicable Number of Common Shares plus
                    such number of shares of Common Stock set out alongside each
                    lower Sustained Production Level or Reserves Value (as
                    applicable) which have not previously been issued. For
                    purposes hereof, the "Applicable Number of Common Shares"
                    means the number of shares of Common Stock set out alongside
                    the relevant Sustained Production Level or Reserves Value in
                    the table below.

               Sustained Production      Number of Shares of         Reserves
                      Level           Common Stock to be Issued        Value

                     8 mmcf/day                8,000,000                 N/A

                    12 mmcf/day                3,000,000                 N/A

                    16 mmcf/day                3,000,000                 N/A

                    20 mmcf/day                3,000,000          $34.15 million

                24 mmcf/day                3,000,000            $37.5 million


               (2)  If by the end of the period ending October 30, 2003 (the
               "Relevant Period"), none of the Sustained Production Levels shall
               have been attained, then at the end of such period each share of
               CRV Stock shall be converted into one-half of one share of Common
               Stock, for a total of 5,000,000 shares of Common Stock.

               (3)  If by the end of the Relevant Period one or more of the
               Sustained Production Levels shall have been attained, but not all
               of the Common Stock shall have been issued as provided by
               paragraph (d)(1) above, then at the end of such period the
               balance of the shares of CRV Stock shall be canceled.

               (4)  Any conversion pursuant to the rights granted by this
               paragraph (d) shall take effect:

                    (i)    in the circumstances described in paragraphs (d)(1)
                    to (d)(3), immediately on the attainment of the relevant
                    Sustained Production Level or at the end of the Relevant
                    Period (as applicable);

                    (ii)   at no cost to the relevant holders and the shares to
                    be issued upon such conversion shall be apportioned rateably
                    (or as near thereto as may be practicable to avoid the
                    apportionment of a fraction of a share) among the holders of
                    that class;

                    (iii)  forthwith after the date of conversion the
                    Corporation shall issue to the persons entitled thereto
                    certificates for the Common Stock;

                    (iv)   the Common Stock issued shall in all respects rank as
                    one uniform class of shares with all other shares of Common
                    Stock of the Corporation;

                    (v)    if, prior to the end of the Relevant Period, the
                    Corporation should split or combine the outstanding Common
                    Stock, recapitalize, or pay a dividend or other distribution
                    on the outstanding Common Stock payable in common stock or
                    other share capital of the Corporation or any other entity
                    controlled by the Corporation, then the number of shares of
                    Common Stock issuable under paragraph (d) shall be
                    appropriately adjusted to reflect such split, combination,
                    recapitalization, dividend or distribution.

               (5)  For purposes of this paragraph, the following terms have the
               indicated meanings:

                    (i)    "East Irish Sea Interests" has the meaning given in

                    dated 23 September 1998.

                    following reserves, bearing interest or discounted at the
                    rate of ten percent (10%), as applicable, net of United

     Re:  American Rivers Oil Company Common Stock

Gentlemen:

     We have acted as counsel to American Rivers Oil Company (the "Company"), a
Delaware corporation, in connection with the registration of 53,684,336 shares
of common stock, par value $0.01 per share, of the Company (the "Common Stock")
pursuant to a Registration Statement on Form S-4 (the "Registration Statement"),
filed with the Securities and Exchange Commission under the Securities Act of
1933 (Regis. No. 333-85237).

     In connection therewith, we have examined and relied upon the original, or
copies, certified to our satisfaction, of (i) the Certificate of Incorporation
(the "Certificate") of the Company; (ii) minutes and records of the corporate
proceedings of the Company with respect to the issuance of the Common Stock and
related matters; (iii) the Registration Statement and exhibits thereto, and (iv)
such other documents and instruments as we have deemed necessary for the
expression of opinions herein contained.  In making the foregoing examinations,
we have assumed the genuineness of all signatures and the authenticity of all
documents submitted to us as originals, and the conformity to original documents
of all documents submitted to us as certified or photostatic copies. As to
various questions of fact material to this opinion and as to the content and
form of the Certificate, minutes, records, resolutions and other documents or
writings of the Company, we have relied, to the extent we deem reasonably
appropriate, upon representations or certificates of officers or directors of
the Company and upon documents, records and instruments furnished to us by the
Company, without independent check or verification of their accuracy.

     Based upon the foregoing examination, we are of the opinion that the Common
Stock to be issued as described in the Registration Statement, has been duly
authorized for issuance and upon issuance, the Common Stock will be validly
issued, fully paid and non-assessable.

               [LETTERHEAD OF JENKENS & GILCHRIST APPEARS HERE]

700 East Ninth Avenue Suite 106
Denver, Colorado  80203

Ladies and Gentlemen:

     We have acted as special tax counsel to American Rivers Oil Company, a
Wyoming corporation (the "Company") in connection with the merger of the Company
into a Delaware corporation ("Newco"), as described in the Form S-4 registration
statement filed with the Securities and Exchange Commission (the "Commission")
on October 13, 1999 (as thereafter amended from time to time and together with
all exhibits thereto, the "Registration Statement").  Except as otherwise
indicated, capitalized terms used herein shall have the meanings assigned to
them in the Registration Statement.

     Set forth below are our opinions and the assumptions and documents upon
which we have relied in rendering our opinions.

     A.   Documents Reviewed
          ------------------

     In connection with the opinions rendered below, we have reviewed and relied
upon the following documents:

          1.   the Registration Statement,

          2.   the Articles of Merger of Newco and the Company,

          3.   the Certificate of Incorporation of Newco and American Rivers Oil
               Company (Delaware),

          4.   the Certificates of the Company, American Rivers Oil Company
               (Delaware) and Newco (the "Certificates"), and

          5.   such other documents as we have deemed necessary or appropriate
               for purposes of this opinion.

     B.   Assumptions
          -----------

     In connection with the opinions rendered below, we have assumed:

          1.   that all signatures on all documents submitted to us are genuine,
that all documents submitted to us as originals are authentic, that all
documents submitted to us as copies are accurate, that all information submitted
to us is accurate and complete, and that all persons executing and delivering
originals or copies of documents examined by us are competent to execute and/or
deliver such documents; and

          2.   that the Merger and the other transactions specified in the
Registration Statement to be effected on or prior to the closing date will be
consummated as contemplated in the Registration Statement and without waiver of
any material provision thereof.

     C.   Opinions
          --------

     Based solely upon the documents and assumptions set forth above, and
conditioned upon the initial and continuing accuracy of the factual
representations set forth in the Certificates as of the date hereof and as of
the date of the effective times of the Merger, it is our opinion that the
descriptions of the law and the legal conclusions contained in the Registration
Statement under the caption "Material United States Federal Tax Consequences of
the Merger" as they relate to the Merger are correct in all material respects
and that the discussion thereunder fairly states the United States federal tax
consequences of the Merger that are likely to be material to the Company and the
shareholders of the Company.

     D.   Limitations

Tulsa, Oklahoma  74135

Ladies and Gentlemen:

     We have acted as special tax counsel to Alliance Resources Plc, a U.K.
public limited company (the "Company") in connection with the offer by American
Rivers Oil Company, a Delaware corporation, to shareholders of the Company to
exchange shares of its common stock solely for shares of ordinary stock in the
Company ("Offer" and "Exchange", respectively), as described in the Form S-4
registration statement filed with the Securities and Exchange Commission (the
"Commission") on October 13, 1999 (as thereafter amended from time to time and
together with all exhibits thereto, the "Registration Statement").  Except as
otherwise indicated, capitalized terms used herein shall have the meanings
assigned to them in the Registration Statement.

     Set forth below are our opinions and the assumptions and documents upon
which we have relied in rendering our opinions.

     A.   Documents Reviewed
          ------------------

     In connection with the opinions rendered below, we have reviewed and relied
upon the following documents:

          1.   the Registration Statement,

          2.   the Certificates of the Company and American Rivers Oil Company
               (Delaware) (the "Certificates"), and

          3.   such other documents as we have deemed necessary or appropriate
               for purposes of this opinion.

     B.   Assumptions
          -----------

     In connection with the opinions rendered below, we have assumed:

          1.   that all signatures on all documents submitted to us are genuine,
that all documents submitted to us as originals are authentic, that all
documents submitted to us as copies are accurate, that all information submitted
to us is accurate and complete, and that all persons executing and delivering
originals or copies of documents examined by us are competent to execute and/or
deliver such documents; and

          2.   that the Exchange and the other transactions specified in the
Registration Statement to be effected on or prior to the closing date will be
consummated as contemplated in the Registration Statement and without waiver of
any material provision thereof.

     C.   Opinions
          --------

     Based solely upon the documents and assumptions set forth above, and
conditioned upon the initial and continuing accuracy of the factual
representations set forth in the Certificates as of the date hereof and as of
the date of the effective times of the Exchange, it is our opinion that the
descriptions of the law and the legal conclusions contained in the Registration
Statement under the caption "Material United States Federal Tax Consequences of
the Merger and Exchange" as they relate to the Exchange are correct in all
material respects and that the discussion thereunder fairly states the United
States federal tax consequences of the Exchange that are likely to be material
to the U.S. Shareholders and non-U.S. Shareholders of the Company.

Alliance Resources PLC
12 St James's Square
London
SW1Y 4RB                                                        October 13, 1999


Dear Sirs

We have acted as legal advisers in the United Kingdom to Alliance Resources PLC
("the Company") in connection with the recommended offer by American Rivers Oil
Company to acquire the whole of the issued share capital of the Company ("the
Offer").

In connection with this opinion, we have examined the following documents:-

1.   the registration statement on form S4 ("the Registration Statement"),
     including the proxy statement/prospectus contained therein, filed with the
     Securities Exchange Commission, relating to the Offer and the registration
     of the common stock of American Rivers Oil Company issued pursuant thereto;

2.   a circular ("the Circular") to be despatched to shareholders of the Company
     who are resident in the United Kingdom.

In connection with this opinion, we have examined and are familiar with
originals or copies, certified or otherwise identified, of such documents and
records of the Company and such statutes and/or regulations as we have deemed
necessary or advisable for the purpose of this opinion.  In rendering this
opinion we have relied upon the facts and disclosures set forth in the
Registration Statement and the Circular regarding the Offer and the issue of
common stock of American Rivers Oil Company pursuant to the Offer. We have not
independently verified the accuracy of such representations or the matters set
forth in such documents or records.  As to certain facts material to this
opinion, we have assumed that all signatures on all documents presented to us
are genuine, that all documents submitted to us as originals are accurate and
complete, that all information supplied to us is accurate and complete and that
all persons executing and delivering originals of copies of documents examined
by us are competent to execute and deliver such documents.

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


Based on the foregoing, this firm is of the opinion that the discussion in the
Registration Statement of the United Kingdom tax treatment of accepting the
Offer under the caption "United Kingdom taxation" within the section headed
"material tax consequences of the merger and exchange" is an accurate summary of
the material United Kingdom tax consequences which may result from shareholders
of the Company accepting the Offer. This firm's opinion is based on current law
and practice, both of which may be subject to changes.  Any such changes may be
retroactive with respect to transactions entered into prior to the date of such
changes and could modify this firm's opinion.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. Consent is also given to the reference to this firm in
the Registration Statement.  In giving this consent, this firm does not thereby
admit that it comes into the category of persons whose consent is required under
section 7 of the Securities Act or the rules and regulations of the commission
promulgated thereunder.

Yours faithfully,

                              EXCHANGE AGREEMENT
                                      FOR
                     CONVERTIBLE RESTRICTED VOTING SHARES


     This Exchange Agreement for Convertible Restricted Voting Shares (the
"Agreement") is entered into as of October 13, 1999, among Alliance Resources
Plc, a public limited company formed under the laws of England and Wales
("Alliance"), American Rivers Oil Company, a Delaware corporation ("AROC"), and
F. Fox Benton, Jr., Lizinka M. Benton, F. Fox Benton III, Lizinka C. Benton and
Lucia T. Benton (collectively, the "Shareholders").

                                   Recitals

     The Shareholders hold an aggregate of 10,000,000 convertible restricted
voting shares ("Convertible Shares") of Alliance pursuant to an Amended and
Restated Sale and Purchase Agreement dated as of September 23, 1998, between the
Shareholders and Alliance.

     Alliance and AROC have entered into an Exchange and Merger Agreement (the
"Exchange and Merger Agreement") dated July 22, 1999, providing among other
things for AROC to offer (the "Offer") to acquire all of the outstanding
ordinary shares of Alliance.

     One of the conditions to the completion of the Exchange and Merger
Agreement is that AROC shall enter into agreements with the Shareholders, on
terms satisfactory to Alliance, providing that after the Offer becomes
unconditional each then outstanding Convertible Share shall be exchanged for the
right to receive shares of the Common Stock of AROC Shares on terms
substantially similar to the terms of the Convertible Shares.

     The parties to this Agreement desire to provide for the exchange of the
Convertible Shares for similar shares of AROC.

     Now, therefore, in consideration of the premises and the mutual agreements
of the parties, the parties to this Agreement hereby agree as follows:

                                   Agreement

1.   AROC and Alliance agree that they will not modify or amend the terms of the
     Offer or the Exchange and Merger Agreement without the consent of the
     Shareholders.

2.   Each of the Shareholders agrees that immediately upon the Offer being
     declared unconditional as provided in Section 2.3 of the Exchange and
     Merger Agreement, each outstanding Convertible Share of Alliance shall be
     exchanged solely for one Convertible Restricted Voting Share (the "CRV
     Stock") of AROC having the terms provided in the form of Certificate of
     Amendment to the Certificate of Incorporation of American Rivers Oil
     Company attached as Exhibit A to this Agreement, and each holder of a
     certificate representing any such Convertible Shares shall thereafter cease
     to have any rights with respect to such Convertible Shares, except the
     right to receive the CRV Stock of AROC upon the surrender of such
     certificate in accordance with Section 3 of this Agreement.  Effective
     immediately upon the Offer being declared unconditional, any and all rights
     of the Shareholders to obtain or receive Deferred Shares of Alliance shall
     be canceled and shall thereafter be of no further force or effect.
<PAGE>

3.   On or after the Offer being declared unconditional, each person who was
     immediately before that time a holder of record of issued and outstanding
     Convertible Shares may deliver to AROC a letter of transmittal duly
     executed and completed in accordance with the instructions thereto,
     together with such holders' certificates representing such Convertible
     Shares, and AROC shall deliver to such holders certificates in respect of
     the CRV Stock of AROC to which such holders are then entitled.

4.   Each of the Shareholders represents and agrees as follows:

          (a)  He or she is the sole legal and beneficial owner of the
               Convertible Shares registered in his or her name, free from any
               encumbrance.

          (b)  He or she has the requisite power and authority to enter into and
               perform this Agreement and this Agreement and any other documents
               executed by him or her in connection with this Agreement will,
               when executed, constitute binding obligations of the Shareholder
               enforceable in accordance with their respective terms.

          (c)  He or she is an "accredited investor" as that term is defined in
               the Securities Act of 1933, as amended, and is acquiring the CRV
               Stock for his or her own account, and has received all
               information he or she believes necessary to evaluate the
               investment in the CRV Stock.

          (d)  The CRV Stock and the Common Stock, whether issued or arising as
               a consequence of conversion, will be "restricted securities"
               under the United States Securities Act of 1933 (as amended) and
               that the ability to resell such CRV Stock and such Common Stock
               will therefore be limited.

5.   Each of Alliance and AROC represents and agrees as follows:

          (a)  The representations and warranties made by each of them in the
               Exchange and Merger Agreement are true and correct.

          (b)  The execution and performance of this Agreement by each of them
               have been duly and validly authorized by the board of directors
               of each of them, and no other corporate action is necessary to
               authorize the execution, delivery and performance of this
               Agreement by each of them. Each of them has full, absolute and
               unrestricted right, power and authority to execute and perform
               this Agreement and to carry out the transactions contemplated
               hereby. This Agreement has been duly and validly executed by each
               of them and this Agreement and any other documents executed by
               them in connection with this Agreement is constitute valid and
               binding obligations of each of them, enforceable in accordance
               with their respective terms.

          (c)  They will not modify or amend the terms of the Offer or the
               Exchange and Merger Agreement without the consent of the
               Shareholders.

6.   Each of the parties hereby acknowledges that for United States federal
     income tax purposes the exchange made pursuant to the Offer, together with
     the exchange by the Shareholders of Convertible Shares for CRV Stock (the
     "Exchange") is intended to constitute a "reorganization" within the

                                       2
<PAGE>

     meaning of section 368(a) of the Internal Revenue Code of 1986, as amended
     (the "Code"), to which Alliance and AROC are parties within the meaning of
     section 368(b) of the Code, and none of the parties shall take any position
     on any tax return or report relating to United States Federal income taxes
     which is inconsistent with such characterization.

7.   Each of the Shareholders agrees that, until October 30, 2001, he or she
     will not sell or otherwise transfer any Common Stock of the Corporation in
     the open market without first providing written notice of his or her intent
     to sell or otherwise transfer such shares to the Secretary of the
     Corporation and thereafter providing the Corporation with a reasonable
     opportunity to identify third parties to purchase such Common Stock upon
     terms and conditions that are reasonable acceptable to the Shareholders and
     such third parties.

8.   Concurrently with the execution of this Agreement, the Shareholders and
     AROC shall execute the Registration Rights Agreement in the form attached
     as Exhibit B, which agreement will be effective upon the Offer being
     declared unconditional.  Upon such execution, the Registration Rights
     Agreement dated October 30, 1998, among the Shareholders and Alliance shall
     be deemed to be terminated and shall be of no further force or effect.

9.   The representations, warranties, covenants and agreements of the parties to
     this Agreement shall survive after the Offer is declared unconditional.

10.  Except as otherwise provided in this Agreement, the parties shall each pay
     their own expenses and costs in connection with this Agreement and the
     transactions contemplated hereby.

11.  Subject to the requirements of law and regulatory bodies, no party shall
     make any public announcement or press release with respect to this
     transaction without first consulting with the other parties and giving such
     parties the opportunity to review and comment thereon.

12.  This Agreement and all of the provisions hereof shall be binding upon and
     inure to the benefit of the parties hereto and their respective heirs,
     personal representatives, successors and permitted assigns. Neither this
     Agreement nor any of the rights, interests or obligations hereunder shall

     person other than the parties hereto or their respective heirs, personal

13.  Any provision of this Agreement that is prohibited or unenforceable in any
     jurisdiction shall, in such jurisdiction, be ineffective to the extent of
     such prohibition or unenforceability without invalidating the remaining
     provisions hereof, and any such prohibition or unenforceability in any
     jurisdiction shall not invalidate or render unenforceable such provision in
     any other jurisdiction.

part its Registrable Securities (a "Demand Registration").

     (b)  Notwithstanding subsection (a) above or anything else herein to the

registrations pursuant to this Section 2; provided, however, that any
registration requested pursuant to this Section 2 will not be deemed to have

order, injunction or other order of the Commission or other governmental agency

event a Demand Registration is requested pursuant to this Section 2, the Company

efforts to effect the registration of the Registrable Securities specified in

                                       3
<PAGE>

     (d)  A registration statement filed under this Section 2 pursuant to the
request of Holders of Registrable Securities may include other securities of the
Company, with respect to which "piggyback" registration rights have been
granted, and may include securities of the Company being sold for the account of
the Company; provided, however, that if the Company shall request inclusion in
any registration pursuant to this Section 2 of the securities being sold for its
own account, or if other persons shall request inclusion in any registration
pursuant to this Section 2, the Shareholders shall offer to include such
securities in the offering and may condition such offer on their acceptance of
any other reasonable conditions (including, without limitation, if such offering
is underwritten, that such requesting holders agree in writing to enter into an
underwriting agreement with usual and customary terms). Notwithstanding any
other provisions of this Section 2, if the representative of the underwriters
advises the Holders of Registrable Securities in writing that marketing factors
require a limitation on the number of shares to be underwritten, the number of
shares to be included in the underwriting or registration shall be allocated
first to the Holders of Registrable Securities, the Benton Holders and LaSalle
(pro rata, based on the number of Registrable Securities requested by each such
holder to be included therein), second to the Company and thereafter to any
other holders requesting inclusion in the registration on the basis of the
number of shares each other requesting holder requests be included bears to the
total number of shares of all other requesting holders that have been requested
be included in such registration.  If a person who has requested inclusion in
such registration as provided above does not agree to the terms of any such
underwriting, such person shall be excluded therefrom by written notice from the
Company, the underwriter, or the Holders of Registrable Securities.  The
securities so excluded shall also be withdrawn from registration.

Section 3.  Piggyback Registration Rights.

     (a)  If the Company proposes to register any of its securities under the
Securities Act other than (i) under employee compensation or benefit programs,
(ii) pursuant to an exchange offer or an offering of securities solely to the
existing stockholders or employees of the Company, or (iii) securities to be
issued in connection with an acquisition or a transaction described in Rule
145(a) promulgated under the Securities Act, and the registration form to be
used may be used for the registration of Registrable Securities, the Company
will give prompt written notice (which, in any event, shall be given no less
than 15 days prior to the filing of a registration statement with respect to
such offering) to Holders of Registrable Securities of its intention to effect
such a registration and, upon the written request of a Holder of Registrable
Securities sent within 15 days after the effective date of any such notice, the
Company will use its best efforts to cause all Registrable Securities as to
which any Holder shall have so requested registration to be registered under the
Securities Act, all to the extent necessary to permit the sale in such offering
of the Registrable Securities so registered on behalf of such Holder in the same
manner as the Company (or stockholder other than such Holder, as the case may
be) proposes to offer its securities (a "Piggyback Registration"). The Company
shall use its best efforts to cause the managing underwriter or underwriters of
a proposed underwritten offering to permit the Registrable Securities requested
by a Holder to be included in the registration for such offering on the same
terms and conditions as any similar securities of the Company included therein;
provided, however, that (A) if, at any time after giving written notice of its
intention to register any of its securities and before the effective date of the
registration statement filed in connection with the registration, the Company
determines for any reason not to register its securities, the Company may, at
its election, give written notice of its determination to the Holders of
Registrable Securities and, thereupon, shall be relieved of its obligation to
register any Registrable Securities in connection with that registration,
without prejudice, however, to the future rights of the Holders of Registrable
Securities under this Section, (B) if the Company determines in its discretion
to delay the registration of its securities, the Company shall be permitted to
delay the registration of any

                                       4
<PAGE>

Registrable Securities for the same period as the delay in registering any other
securities, and (C) the Company is not required to effect any registration for a
requesting Holder of Registrable Securities pursuant to this Section 3 unless it
receives reasonable assurances that the requesting Holder of Registrable
Securities will pay any expenses required to be paid by it as provided in
Section 5.

     (b)  If a Piggyback Registration is an underwritten registration and the
managing underwriter(s) for the offering advises the Company in writing that in
its opinion the number of shares of Registrable Securities requested or proposed
to be included in the registration exceeds the number that can be sold in the
offering without materially affecting the offering price of the securities
proposed to be included in the offering, then the number of securities to be
offered for the account of any participating Holder(s) shall be reduced pro rata
based upon the number of securities proposed to be sold by the Company, such
Holder(s) and other Persons to the extent necessary to reduce the total number
of securities to be included in such offering to the number of shares
recommended by such managing underwriter; provided, however, that if securities
of the Company are being offered for the account of other Persons as well as the
Company, such reduction shall first be made from the securities intended to be
offered by such Persons other than the participating Holder(s), the Benton
Holders and LaSalle.

     (c)  If any Piggyback Registration is an underwritten offering, the Company
will have the sole right to select the managing underwriter(s) thereof.

     (d)  The rights of the Holders with respect to Piggyback Registrations
shall be pari passu with the piggyback registration rights of the Benton Holders
and LaSalle.

Section 4.  Registration Procedures.

     (a)  Whenever the Holders of Registrable Securities have requested that any
Registrable Securities be registered pursuant to Section 2 or Section 3, the
Company will as expeditiously as possible:

            (i)   prepare and file with the Commission a registration statement
on the appropriate form with respect to such Registrable Securities, and use its
reasonable best efforts to cause such registration statement to become effective
as soon as reasonably practicable after the filing thereof; provided, however,
that the Company may discontinue any registration of securities that is being
effected pursuant to Section 3 at any time prior to the effective date of the
registration statement relating thereto, and provided further, that before
filing a registration statement or prospectus or any amendments or supplements
thereto, including documents incorporated by reference after the initial filing
of any registration statement, as soon as practicable, the Company will furnish
to any Holder covered by such Registration Statement copies of all such
documents proposed to be filed, which documents will be subject to the review of
such Holder;

            (ii)  prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
a period of not less than the period set forth in  such section or such shorter
period which will terminate when Registrable Securities covered by such
registration statement have been sold (but not before the expiration of the
applicable prospectus delivery period) and comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement during such period in accordance with the intended
methods of disposition by the sellers thereof set forth in such registration
statement;

                                       5
<PAGE>

            (iii)  notify each seller of Registrable Securities requesting
registration, promptly after the Company shall receive notice thereof, of the
time when such registration statement has been filed;

            (iv)   furnish without charge to each seller of Registrable
Securities such number of copies of such registration statement, each amendment
and supplement thereto, including financial statements and schedules, all
documents incorporated therein by reference and all exhibits (including those
incorporated by reference); the prospectus included in such registration
statement (including, without limitation, each preliminary prospectus); and such
other documents as such seller may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by such seller;

            (v)    use its reasonable best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such
jurisdictions within the United States as any seller reasonably requests; keep
each such registration or qualification effective during the period such
registration statement is required to be kept effective; and do any and all
other acts and things which may be reasonably necessary or advisable to enable
such seller to consummate the disposition in such jurisdictions of the
Registrable Securities owned by such  seller (provided that the Company will not
for any such purpose be required to (1) qualify generally to do business as a
foreign corporation in any jurisdiction where it would not otherwise be required
to qualify but for the requirements of this subsection; (2) subject itself to
taxation in any such jurisdiction; (3) consent to general service of process in
any such jurisdiction; or (4) register or qualify Registrable Securities or take
any other action under the state securities or "Blue Sky" laws of any
jurisdiction if, in the reasonable good faith judgment of the Board of
Directors of the Company, the consequences of the registration, qualification or
other action would be unduly burdensome to the Company);

            (vi)   notify each seller of such Registrable Securities, at any
time when a prospectus relating thereto is required to be delivered under the
Securities Act, of the happening of any event which requires the making of any
change in the prospectus included in such registration statement so that such
document will not contain an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading, and, at the request of any such seller, the
Company will prepare a supplement or amendment to such prospectus so that such
prospectus will not contain an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading;

            (vii)  use its reasonable best efforts to cause all such Registrable
Securities to be listed on each securities exchange or exchanges, automated
quotation system or over-the-counter market upon which securities of the Company
of the same class are then listed;

            (viii) enter into such customary agreements (including, without
limitation, underwriting agreements in customary form, substance and scope) and
take all such other action as the Holders of a majority of the Registrable
Securities being sold or the underwriters, if any, reasonably request in order
to expedite or facilitate the disposition of such Registrable Securities;

            (ix)   otherwise use its reasonable best efforts to comply with all
applicable rules and regulations of the Commission;

            (x)    in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any securities included in such registration statement for sale in any

                                       6
<PAGE>

jurisdiction, the Company will use its reasonable best efforts promptly to
obtain the withdrawal of such order;

            (xi)   use its reasonable best efforts to cause such Registrable
Securities covered by such registration statement to be registered with or
approved by such other foreign and domestic governmental agencies or authorities
as may be necessary to enable the sellers thereof to consummate the disposition
of such Registrable Securities;

            (xii)  use its reasonable best efforts to obtain a comfort letter
from the Company's public accountants in customary form and covering such
matters of the type customarily covered by comfort letters with respect to
offerings of the type being made pursuant to the registration statement as the
Holders of the Registrable Securities reasonably request; and

            (xiii) cooperate with each seller of such Registrable Securities to
facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be sold and not bearing any restrictive legends.

     (b)  Whenever the Holders of Registrable Securities have requested that any
Registrable Securities be registered pursuant to Section 2 or Section 3, each
Holder of Registrable Securities (including Registrable Securities in any
registration statement filed pursuant to this Agreement) will be deemed to have
agreed as follows:

            (i)    upon receipt of any notice from the Company of the happening
of any event of the kind described in Section 4(a)(vi), the Holders of
Registrable Securities covered by such registration statement will forthwith
discontinue disposition of any such Registrable Securities until the Holders of
Registrable Securities receive copies of the supplemented or amended prospectus
contemplated by Section 4(a)(vi), or until they are advised in writing by the
Company that the use of the applicable prospectus may be resumed, and they have
received copies of any additional or supplemental filings that are incorporated
or deemed to be incorporated by reference in such prospectus (it being the
agreement of the parties hereto, however, that the obligation of the Company
with respect to maintaining the subject registration statement current and
effective shall be extended by a period of days equal to the period the Holders
of Registrable Securities are required by this Section 4(b)(i) to discontinue
disposition of such Registrable Securities); and

            (ii)   furnish to the Company such information regarding each
Holder, the Registrable Securities held by such Holder, the intended method of
disposition thereof and such other information as the Company shall reasonably
request and as shall be reasonably required in connection with the preparation
of the applicable registration statement and other actions taken by the Company
under this Agreement.

     (c)  The Company may postpone the filing of any registration statement
required under Section 2 for a reasonable period of time, if (i) the Company has
been advised by legal counsel reasonably acceptable to the Holders of a majority
of the Registrable Securities that such filing would require the disclosure of a
material fact, and the Company determines reasonably and in good faith that such
disclosure would have a material adverse effect on the Company or (ii) (A) in
the good faith judgment of the Board of Directors of the Company, a required
registration under Section 2 would be seriously detrimental to the Company and
the Board of Directors of the Company concludes, as a result, that it is
essential to defer the filing of such registration statement at such time, and
(B) the Company shall furnish

                                       7
<PAGE>

to the Holders of Registrable Securities a certificate signed by the President
of the Company stating that in the good faith judgment of the Board of Directors
of the Company, it would be seriously detrimental to the Company for such
registration statement to be filed in the near future and that it is, therefore,
essential to defer the filing of such registration statement; provided, however,
that under no circumstances shall one or more delays pursuant to this Section
4(c) extend beyond the earlier to occur of (x) the expiration of a period of
ninety (90) days after receipt of the request of a Holder of Registrable
Securities and (y) that point in time at which the conditions described above no
longer exist; and, provided further, that the Company shall not defer its
obligation pursuant to this Section 4(c) more than once in any twelve-month
period.

Section 5.  Expenses of Registration.  The Company shall pay all Registration
Expenses in connection with each registration effected pursuant to Sections 2
and 3 and, in any event, shall pay its internal expenses (including, without
limitation, all salaries and expenses of its officers and employees performing
legal and accounting duties), the expense of any annual audit and the fees and
expenses incurred in connection with the listing of the securities to be
registered on each securities exchange or market on which similar securities
issued by the Company are then listed.  All Selling Expenses incurred in
connection with a registration effected pursuant to the terms hereof shall be
borne by the seller or sellers of Registrable Securities.

Section 6.  Indemnification.

     (a)  The Company shall indemnify and hold harmless, with respect to any
registration statement filed by it, to the fullest extent permitted by law, each
Holder of Registrable Securities covered by such registration statement, and
each other Person, if any, who controls such Holder within the meaning of
Section 15 of the Securities Act (collectively, "Holder Indemnified Parties")
against all losses, claims, damages, liabilities and expenses, joint or several
to which any such Holder Indemnified Party may become subject under the
Securities Act, the Exchange Act, at common law or otherwise, insofar as such
losses, claims, damages, liabilities or expenses (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon (i) any untrue statement or alleged untrue statement of a material fact
contained in any registration statement in which such Registrable Securities
were included as contemplated hereby, or any post-effective amendment thereof,
or any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
(ii) any untrue statement or alleged untrue statement of a material fact
contained in any preliminary, final or summary prospectus, together with the
documents incorporated by reference therein (as amended or supplemented if the
Company shall have filed with the Commission any amendment thereof or supplement
thereto), or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or (iii) any violation by the Company of any federal, state or
common law rule or regulation applicable to the Company and relating to action
of or inaction by the Company in connection with any such registration; and in
each such case, the Company shall reimburse each such Holder Indemnified Party
for any reasonable legal or other expenses incurred by any of them in connection
with investigating or defending any such loss, claim, damage, liability,
expense, action or proceeding; provided, however, that the Company shall not be
liable to any such Holder Indemnified Party in any such case to the extent that
any such loss, claim, damage, liability or expense (or action or proceeding,
whether commenced or threatened, in respect thereof) arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged
omission made in such registration statement or amendment thereof or supplement
thereto or in any such preliminary, final or summary prospectus in reliance upon
and in conformity with written information furnished to the

                                       8
<PAGE>

Company by or on behalf of any such Holder Indemnified Party for use in the
preparation thereof; provided further that the Company shall not be liable to
any such Holder Indemnified Party in any such case to the extent that any such
loss, claim, damage, liability or expense (or action or proceeding, whether
commenced or threatened, in respect thereof) arises out of or is based upon any
untrue statement or alleged untrue statement or omission or alleged omission
made in any preliminary prospectus if (A) such holder failed to send or deliver
a copy of the prospectus with or prior to the delivery of written confirmation
of the sale of Registrable Securities and (B) the prospectus would have
completely corrected such untrue statement or omission; provided further that
the Company shall not be liable in any such case to the extent that any such
loss, claim, damage, liability or expense arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission in
the prospectus, if such untrue statement or alleged untrue statement, omission
or alleged omission is completely corrected in an amendment or supplement to the
prospectus and if, having previously been furnished by or on behalf of the
Company with copies of the prospectus as so amended or supplemented, such holder
thereafter fails to deliver such prospectus as so amended or supplemented, prior
to or concurrently with the sale of a Registrable Security to the person
asserting such loss, claim, damage, liability or expense who purchased such
Registrable Security which is the subject thereof from such holder. Such
indemnity and reimbursement of expenses and other obligations shall remain in
full force and effect regardless of any investigation made by or on behalf of
the Holder Indemnified Parties and shall survive the transfer of such securities
by such Holder Indemnified Parties.

     (b)  Each Holder of Registrable Securities participating in any
registration hereunder shall severally (and not jointly or jointly and
severally) indemnify and hold harmless, to the fullest extent permitted by law,
the Company, its directors, each of its officers who has signed the registration
statement and each Person who controls the Company (within the meaning of
Section 15 of the Securities Act) (collectively, "Company Indemnified Parties")
against all losses, claims, damages, liabilities and expenses to which any
Company Indemnified Party may become subject under the Securities Act, the
Exchange Act, at common law or otherwise, and will reimburse each such Company
Indemnified Party for any reasonable legal or other expenses incurred by any of
them in connection with investigating or defending any such loss, claim, damage,
liability, expense, action or proceeding, but only insofar as such losses,
claims, damages, liabilities or expenses (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of a material fact contained in
any registration statement in which such Holder's Registrable Securities were
included or the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, (ii) any untrue statement or alleged untrue statement of a material
fact contained in any preliminary, final or summary prospectus, together with
the documents incorporated by reference therein (as amended or supplemented if
the Company shall have filed with the Commission any amendment thereof or
supplement thereto), or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, in each case to the extent (and only to the extent) that
such untrue statement or omission or alleged untrue statement or omission was
made in reliance upon and in conformity with information furnished in writing by
or on behalf of such Holder specifically for use in connection with such
registration, (iii) any violation by the Holder of any federal, state or common
law, rule or regulation applicable to the Holder and relating to action of or
inaction by the Holder in connection with any registration statement and (iv)
with respect to any preliminary prospectus, the fact that the Holder sold
Registrable Securities to a person to whom there was not sent or given, at or
prior to the written confirmation of the sale, a copy of the prospectus
(excluding documents incorporated by reference) or of the prospectus as then
amended or supplemented (excluding documents incorporated by reference) if (a)
the Company has previously furnished copies

                                       9
<PAGE>

thereof to the Holder in compliance with Section 4 and (b) the loss, claim,
damage, liability or expense of the Company Indemnified Party results from an
untrue statement or omission of a material fact contained in the preliminary
prospectus which was corrected in the prospectus (or the prospectus as amended
or supplemented). Such indemnity obligation shall remain in full force and
effect regardless of any investigation made by or on behalf of the Company
Indemnified Parties (except as provided above) and shall survive the transfer of
such securities by such Holder.

     (c)  Promptly after receipt by an indemnified party under subsection (a) or
(b) of written notice of the commencement of any action, suit, proceeding,
investigation or threat thereof made in writing with respect to which a claim
for indemnification may be made pursuant to this Section 6, such indemnified
party shall, if a claim in respect thereof is to be made against an indemnifying
party, give prompt written notice to the indemnifying party of the threat or
commencement thereof; provided, however, that the failure to so promptly notify
the indemnifying party shall not relieve it from any liability which it may have
to any indemnified party except to the extent that the indemnifying party is
actually prejudiced by such failure to give prompt notice.  If any such claim or
action referred to under subsection (a) or (b) is brought against any
indemnified party and it then notifies the indemnifying party of the threat or
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it wishes, jointly with any other indemnifying
party similarly notified, to assume the defense thereof with counsel reasonably
satisfactory to such indemnified party.  After notice from the indemnifying
party to such indemnified party of its election so to assume the defense of any
such claim or action, the indemnifying party shall not be liable to such
indemnified party under this Section 6 for any legal expenses of counsel or any
other expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation unless the
indemnifying party has failed to assume the defense of such claim or action or
to employ counsel reasonably satisfactory to such indemnified party.  Under no
circumstances will the indemnifying party be obligated to pay the fees and
expenses of more than one law firm for all indemnified parties.  The
indemnifying party shall not be required to indemnify the indemnified party with
respect to any amounts paid in settlement of any action, proceeding or
investigation entered into without the written consent of the indemnifying
party, which consent shall not be unreasonably withheld.  No indemnifying party
shall consent to the entry of any judgment or enter into any settlement without
the consent of the indemnified party unless (i) such judgment or settlement does
not impose any obligation or liability upon the indemnified party other than the
execution, delivery or approval thereof, and (ii) such judgment or settlement
includes as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a full release and discharge from all
liability in respect of such claim.

     (d)  Indemnification similar to that specified in the preceding subsections
of this Section 6 (with appropriate modifications) shall be given by the Company
and each seller of Registrable Securities with respect to any required
registration or qualification of securities under any state securities or blue
sky laws.

     (e) If the indemnification provided for in this Section 6 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a) or
(b), then each indemnifying party shall contribute to the amount paid or payable
by such indemnified party as a result of the losses, claims, damages,
liabilities or expenses (or actions or proceedings in respect thereof) referred
to in subsection (a) or (b) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and the indemnified
party on the other in connection with the statements, omissions, actions or
inactions which resulted in such losses, claims, damages, liabilities or
expenses as well as any other relevant equitable considerations. The relative
fault of the indemnifying party and the indemnified party shall be determined

                                       10
<PAGE>

by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the indemnifying party or the
indemnified party, any action or inaction by any such party, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement, omission, action or inaction. The amount paid or payable
by an indemnified party as a result of the losses, claims, damages, liabilities
or expenses (or actions or proceedings in respect thereof) pursuant to this
subsection (e) shall be deemed to include, without limitation, any reasonable
legal or other expenses incurred by such indemnified party in connection with
investigating or defending any such action or claim (which shall be limited as
provided in subsection (c) if the indemnifying party has assumed the defense of
any such action in accordance with the provisions thereof) which is the subject
of this subsection (e). No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. Promptly after receipt by an indemnified party under this
subsection (e) of written notice of the commencement of any action, suit,
proceeding, investigation or threat thereof made in writing with respect to
which a claim for contribution may be made against an indemnifying party under
this subsection (e), such indemnified party shall, if a claim for contribution
in respect thereof is to be made against an indemnifying party, give prompt
written notice to the indemnifying party in writing of the commencement thereof
(if the notice specified in subsection (c) has not been given with respect to
such action); provided, however, that the failure to so promptly notify the
indemnifying party shall not relieve it from any obligation to provide
contribution which it may have to any indemnified party under this subsection
(e) except to the extent that the indemnifying party is actually prejudiced by
the failure to give prompt notice.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this paragraph were determined by pro rata allocation
or by any other method of allocation which does not take account the equitable
considerations referred to in the immediately preceding paragraph.

     If indemnification is available under this Section 6, the indemnifying
parties shall indemnify each indemnified party to the fullest extent provided in
subsections (a) and (b), without regard to the relative fault of said
indemnifying party or any other equitable consideration provided for in this
subsection.  The provisions of this subsection shall be in addition to any other
rights to indemnification or contribution which any indemnified party may have
pursuant to law or contract, shall remain in full force and effect regardless of
any investigation made by or on behalf of any indemnified party, and shall
survive the transfer of securities by any such party.

     (f)  In connection with any underwritten offering contemplated by this
Agreement which includes Registrable Securities, the Company and all sellers of
Registrable Securities included in any registration statement shall agree to
customary provisions for indemnification and contribution (consistent with the
other provisions of this Section 6) in respect of losses, claims, damages,
liabilities and expenses of the underwriters of such offering.

Section 7.  Selection of Underwriters.  If a registration effected pursuant to
Section 2 is an underwritten offering or a best efforts underwritten offering,
the investment bankers or investment bankers and manager or managers that will
administer the offering shall be selected by the Holders of a majority of the
Registrable Securities to be registered in such registration; provided, however,
that such investment bankers and managers must be reasonably satisfactory to the
Company.

Section 8.  Rule 144.  The Company covenants to each Holder that, to the extent
that the Company shall be required to do so under the Exchange Act, the Company
shall (a) timely file the reports required to be

                                       11
<PAGE>

filed by it under the Exchange Act or the Securities Act (including, but not
limited to, the reports under Section 13 and 15(d) of the Exchange Act referred
to in subparagraph (c) (1) of Rule 144 adopted by the Commission under the
Securities Act) and the rules and regulations adopted by the Commission
thereunder, and (b) take such further action as any Holder may reasonably
request, all to the extent required from time to time to enable such Holder to
sell Registrable Securities without registration under the Securities Act within
the limitations of the exemption provided by Rule 144 under the Securities Act,
as such Rule may be amended from time to time, or any similar rule or regulation
hereafter adopted by the Commission. Upon the reasonable request of any Holder,
the Company shall deliver to such Holder a written statement as to whether it
has complied with such requirements.

Section 9.  Participation in Underwritten Registrations.  In the case of a
registration hereunder, if the Company has determined to enter into an
underwriting agreement in connection therewith, all shares of Registrable
Securities to be included in such registration shall be subject to the
underwriting agreement, which shall be in customary form and contain such terms
as are customarily contained in such agreements, and the Holders may not
participate in any such registration unless the Holder (a) agrees to sell its
securities on the basis provided in any underwriting arrangements and (b)
completes and executes all questionnaires, power of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of the underwriting arrangements.

Section 10. Rights to Withdraw From Registration.  If, as a result of the
proration provisions of Section 3(b) a Holder is not entitled to include all
Registrable Securities in a registration that the Holder has requested to be
included, the Holder may elect to withdraw its request to include Registrable
Securities in the registration (a "Withdrawal Election"); provided, however,
that a Withdrawal Election shall be irrevocable and, after making a Withdrawal
Election, the Holder shall no longer have any right to include Registrable
Securities in the registration as to which the Withdrawal Election was made.

Section 11. Existing Registration Rights.  The Company represents and warrants
to, and covenant with, the Shareholders that, as of the date hereof, the Company
has not entered into any agreement, written or oral, granting or otherwise
affording to a third party registration rights with respect to any securities
held by such third party in the Company, except for the Benton Agreement and the
LaSalle Agreement.

Section 12. Miscellaneous.

     (a)    From and after the date of this Agreement, the Company will not
enter into any agreement with respect to its securities which is inconsistent
with or violates the rights granted to the Holders of Registrable Securities in
this Agreement.

Securities in any registration statement filed pursuant to this Agreement)
agrees as follows:

              (i)  if any Registrable Securities are being registered in any
registration pursuant to this Agreement, the Holder thereof will comply with all
anti-stabilization, manipulation and similar provisions of Section 10 of the
Exchange Act, as amended, and any rules promulgated thereunder by the Commission
and, at the request of the Company, will execute and deliver to the Company and
to any underwriter participating in such offering, an appropriate agreement to
such effect; and

                                       12
<PAGE>

            (ii)  at the end of any period during which the Company is obligated
to keep a registration statement current and effective as described herein, the
Holders of Registrable Securities included in the registration statement shall
discontinue sales thereof pursuant to such registration statement.

     (c)  In order to facilitate the possibility of future public offerings of
Common Stock, the Holders (and any subsequent Holder) agree that the Registrable
Securities will not be resold during a period commencing on the filing by the
Company of a registration statement under the Securities Act for an underwritten
public offering for cash by the Company of its Common Stock or securities
convertible into or exercisable or exchangeable for its Common Stock and
continuing until the earlier of the abandonment of the proposed public offering
or 120 days following the date of the last closing in the public offering
without the consent of the underwriters of such offering, except to the extent
such shares are included in such registration. Holders of such Registrable
Securities also agree that they will cooperate with the Company in providing
reasonable written assurances respecting the foregoing to the underwriter of any
such public offering.  Holders agree that during the above restricted period
they will not directly or indirectly sell, offer to sell, contract to sell
(including without limitation any short sale), grant an option to purchase or
otherwise transfer or dispose of (other than to donees who agree to be similarly
bound) shares of Registrable Securities at any time during such period except
securities included in such registration.  In order to enforce the foregoing
covenant, the Company may impose stop-order instructions with respect to such
shares of Registrable Securities held by each Holder, which shall be binding
upon any assignee or successor of such Holder (and the shares or securities of
every other person subject to the foregoing restriction), until the end of the
restricted period.

     (d)  All questions concerning the construction, validity and interpretation
of this Agreement shall be governed by the internal law, and not the law of
conflicts, of the State of Delaware.

     (e)  All covenants and agreements in this Agreement by or on behalf of any
of the parties hereto will bind and inure to the benefit of the respective
successors and assigns of the parties hereto. In addition, the rights and
obligations under this Agreement shall  automatically be transferred to and
binding on any transferee or assignee of the Registrable Securities; provided,
that (i) the Company is, within a reasonable time after such transfer, furnished
with written notice of the name and address of such transferee or assignee and
the Registrable Securities with respect to which such registration rights are
being transferred or assigned, (ii) such transferee or assignee agrees in
writing to be bound by and subject to the terms and conditions of this
Agreement, (iii) the transfer and assignment of the subject Registrable
Securities is in compliance with (A) the Purchase Agreement and (B) the
Securities Act and applicable state securities laws or an exemption from the
registration requirements of the Securities Act and applicable state securities
laws, (iv) such assignment of rights and obligations under this Agreement shall
be effective only if immediately following such transfer the further disposition
of such Registrable Securities by the transferee or assignee is restricted under
the Securities Act and (v) the transferee acquires at least 10% of the
Registrable Securities originally acquired by the Shareholders from the Company.

     (f)  This Agreement is intended by the parties as a final expression of
their agreement and intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto in respect of the subject
matter herein contained. There are no restrictions, promises, warranties or
undertakings, other than those set forth or referred to herein, with respect to

Section 2.  Piggyback Registration.  If at any time or from time to time after
the date hereof AROC proposes to effect a Piggyback Registration for its account
or for the account of a security holder or holders (other than holders of
Registrable Securities), then AROC shall:

     (a)  promptly give to each holder of Registrable Securities notice thereof
(which notice shall include a list of the jurisdictions in which AROC intends to
attempt to qualify such securities under or otherwise comply with the applicable
blue sky or other state securities laws); and

     (b)  include in such Piggyback Registration (and any related qualification
under or other compliance with blue sky or other state securities laws), and in
any underwriting involved therein, all the Registrable Securities specified in a
request, made within 15 days after receipt of such notice from AROC, by any
holder of Registrable Securities; provided, however, that AROC shall not be
required to include any securities of holders of Registrable Securities in such
registration unless such holders accept the terms of the underwriting as agreed
upon between AROC and the underwriters selected by it; and provided, further,
that if such Piggyback Registration is a Cutback Registration, then the number
of shares

                                       3
<PAGE>

of Common Stock to be included in the underwriting or registration shall be
allocated first to AROC, the holders of Registrable Securities and the Electing
Holders (pro rata, based on the total number of shares of securities of AROC,
including Registrable Securities, requested by AROC and each such holder to be
included therein); and thereafter to any other holders requesting inclusion in
the registration on the basis of the number of shares each other requesting
holder requests be included bears to the total number of shares of all other
holders of Common Stock that have been requested be included in such
registration. If a person who has requested inclusion in such registration as
provided above does not agree to the terms of any such underwriting, such person
shall be excluded therefrom by written notice from AROC, the underwriter, or the
holders of Registrable Securities. The securities so excluded shall also be
withdrawn from registration.

     (c)  (i) If, at any time after giving written notice of its intention to
register any of its Common Stock and before the effective date of the
registration statement filed in connection with the registration, AROC
determines for any reason not to register its Common Stock, AROC may, at its
election, give written notice of its determination to the holders of Registrable
Securities and the Electing Holders and, thereupon, shall be relieved of its
obligation to register any Registrable Securities in connection with that
registration, without prejudice, however, to the future rights of the holders of
Registrable Securities under this Section, (ii) if AROC determines in its
discretion to delay the registration of its Common Stock, AROC shall be
permitted to delay the registration of any Registrable Securities for the same
period as the delay in registering any other Common Stock, and (iii) AROC is not
required to effect any registration for a requesting holder of Registrable
Securities pursuant to this Section 2 unless it receives reasonable assurances
that the requesting holder of Registrable Securities will pay any expenses
required to be paid by it as a provided in Section 5.

     (d)  The rights of holders with respect to Piggyback Registrations shall be
pari passu with the piggyback registration rights of Benton Holders and the
EnCap Holders.

Section 3.  Requested Registration.

3.01.  Request for Registration.

     (a)  If after the date AROC shall receive a request from any holder of
Registrable Securities (including Warrants) that AROC effect any registration
under the Securities Act to which such holder is entitled under this Section 3
(including without limitation any related qualification under or compliance with
blue sky or other state securities laws) with respect to all or a part of the
Registrable Securities owned by such holder, then AROC shall promptly give
notice of such request to each other holder of Registrable Securities, and AROC
shall thereupon promptly use its best efforts diligently to effect such
Requested Registration and related qualifications and compliances within 120
days after receiving such request for registration (including without limitation
the execution of an undertaking to file post-effective amendments and
appropriate qualifications under or other compliance with the applicable blue
sky or other state securities laws) as may be reasonably requested by the holder
of Registrable Securities who made the original request (the "Original
Requesting Holder") and by the holders of Registrable Securities who make
requests to AROC within 15 days after the giving of the aforesaid notice by AROC
(each of the foregoing an "Other Requesting Holder") and as would permit or
facilitate the sale and distribution of all or such portion of the Registrable
Securities as are specified in any such request; provided, however, that AROC
shall not be obligated to take any action to effect a Requested Registration or
any related qualification or compliance pursuant to this Section 3:

                                       4
<PAGE>

          (i)   if the Requesting Holders do not request to include in such
registration Registrable Securities (issued or issuable on exercise of the
Warrants) having an aggregate Current Adjustment Price (as defined in the
Warrants), determined as of the date of the notice from the Original Requesting
Holder under Section 3.01(a) of (A) at least $750,000 for the holders' first
Requested Registration or (B) at least $250,000 for the holders' second
Requested Registration;

          (ii)  if AROC shall have already effected two Requested Registrations
on behalf of the holders of Registrable Securities pursuant to this Section
3.01, each of which Requested Registrations (A) has been declared or ordered
effective (including without limitation qualification under or other compliance
with state blue sky or securities laws requested) and which effectiveness has
not been suspended or stopped by any governmental or judicial authority, and (B)
remains continuously effective for a period of time not less than the Effective
Period; or

          (iii) if, within 30 days after receipt of the initial request of the
Original Requesting Holder pursuant to this Section 3.01, AROC shall elect to
include in such registration Common Stock for its own account, whereupon AROC
shall notify each Requesting Holder that AROC has elected to effect a Piggyback
Registration and shall thereafter diligently proceed to do so, including therein
the Registrable Securities as to which notice was given by the Requesting
Holders pursuant to this Section 3.01, but subject to the limitations set forth
in Section 2(b)(i) (it being understood, however, that such registration shall
not be deemed to be a Requested Registration for the purposes of Sections
3.01(a)(ii) or 3.01(c)).

          (iv)  Notwithstanding the foregoing, (A) AROC shall not be obligated
to effect a registration pursuant to this Section 3 during the period starting
with the date 60 days prior to AROC's good faith estimated date of filing of,
and ending on a date 120 days following the effective date of, a registration
statement pertaining to an underwritten public offering of securities for the
account of AROC, provided that AROC is at all times during such period
diligently pursuing such registration, (B) AROC shall not be obligated to effect
a registration of Registrable Securities pursuant to this Section 3 pursuant to
any request of Holders of Registrable Securities if such request is received
after the receipt by AROC of a request for registration pursuant to one of the
Registration Agreements, and any such registration pursuant to this Section 3
would likely result in a registration statement being declared effective prior
to the date that is 90 days after the effective date of any such registration
effected pursuant to the Registration Agreement, and (C) AROC shall not be
obligated to effect a registration pursuant to this Section 3 and shall have the
right to defer such filing for a period of not more than 120 days after receipt
of the request of holders of Registrable Securities, if AROC shall furnish to
such holders a certificate signed by the President of AROC stating that in the
good faith judgment of the Board of Directors of AROC, it would be seriously
detrimental to AROC and its shareholders for such registration statement to be
filed and it is therefore essential to defer the filing of such registration
statement; provided, however, that, subject to the limitation set forth in the
proviso in Section 3.01(a)(ii), if AROC shall no longer be eligible to effect a
Short-Form Requested Registration following the deferral of registration
pursuant to this paragraph, then the holders of Registrable Securities shall,
subject to Section 3.01(a)(ii), be entitled to a Long-Form Requested
Registration for each such deferral.

          (v)   If at any time after the holders' initial Requested
Registration, a request of the holders of Registrable Securities for a Requested
Registration shall be denied by AROC solely because the aggregate Current
Adjustment Price of such Registrable Securities sought to be included in such
registration is below the requisite dollar amount specified in Section
3.01(a)(i)(B), then at the election of the holders of a majority of the then
outstanding Registrable Securities, and in exchange for the right of the holders
to request a second Requested Registration under this Section 3, the holders
shall be entitled to

                                       5
<PAGE>

convert their Registrable Securities represented by Warrants (having an
aggregate Current Adjustment Price for all holders of not more than $250,000)
pursuant to Section 12 of the Warrant.

     (b)  If a Requested Registration becomes a Cutback Registration and the
number of shares of Registrable Securities actually sold in such Requested
Registration is not at least a majority of the number of shares of Registrable
Securities requested to be included in such registration, then (A) such
Requested Registration shall not be deemed to be a Requested Registration for
the purposes of Section 3.01(a)(ii); and (B) notwithstanding that such Requested
Registration is a Cutback Registration, AROC shall continue to use its best
efforts diligently to comply with all its obligations (including without
limitation payment of expenses) under this Agreement with respect to such
Requested Registration.  The registration statement filed pursuant to the
request of holders of Registrable Securities may, subject to the provisions of
Section 3.01(c), include other shares of Common Stock of AROC, which are held by
persons who, by virtue of agreements with AROC, are entitled to include their
securities in any such registration, and AROC shall have the right to include
shares of Common Stock in such registration for its own account as provided
therein.

     (c)  If a Requested Registration becomes a Cutback Registration, the number
of Common Stock to be included in the underwriting or registration shall be
allocated first to the holders of Registrable Securities and the Electing
Holders (pro rata, based on the number of Registrable Securities requested by
each such holder to be included therein), second to AROC and thereafter to any
other holders requesting inclusion in the registration on the basis of the
number of shares each other requesting holder requests be included bears to the
total number of shares of all other holders of Common Stock that have been
requested be included in such registration.  If a person who has requested
inclusion in such registration as provided above does not agree to the terms of
any such underwriting, such person shall be excluded therefrom by written notice
from AROC, the underwriter, or the holders of Registrable Securities. The
securities so excluded shall also be withdrawn from registration.

3.02.  Underwriting. If Requesting Holders intend to distribute the Registrable
Securities covered by such request by means of an underwriting, the Requesting
Holders shall so advise AROC as a part of the request made pursuant to this
Section 3, and in such event, the Requesting Holders shall negotiate in good
faith with an underwriter or underwriters proposed by AROC to act as the
Managing Underwriter in connection with the underwriting of the Requested
Registration; provided, however, that if those Requesting Holders who hold at
least a majority of the Registrable Securities to be included in such Requested
Registration have not agreed with such underwriter or underwriters as to the
terms and conditions of such underwriting within 20 days following commencement
of such negotiations, then the Requesting Holders may select an underwriter or
underwriters of their choice to be the Managing Underwriter, which choice shall
be subject to the approval of the Board of Directors of AROC (such approval not
to be unreasonably withheld or delayed, taking into account AROC's agreements
with underwriters then in effect).AROC and the Requesting Holders shall enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting (it being understood that (i) all
expenses customarily paid for by the issuer of securities pursuant to such an
underwriting agreement shall be paid for by AROC, and (ii) all indemnification
obligations which are customarily those of the issuer of securities under such
underwriting agreement shall be the obligations of AROC).If a Requesting Holder
disapproves of the terms of an underwriting (the "Withdrawing Holder"), the
Withdrawing Holder may elect to withdraw therefrom by notice to AROC and the
Managing underwriter; and each of the remaining Requesting Holders shall be
entitled to increase the number of shares of Registrable Securities being
registered to the extent of the shares withdrawn by the Withdrawing Holder in
the proportion which the number of shares of Registrable Securities being
registered by such remaining Requesting Holder bears to the total number of
shares being

                                       6
<PAGE>

registered by all such remaining Requesting Holders; provided, however, that the
requirements contained in Section 3.01(a)(i) shall then be met and subject to
Section 3.01(c).

Section 4.  Expenses of Registration.

     Except as otherwise provided herein, (a) in the case of Requested
Registrations pursuant to Section 3, all expenses incurred by AROC or the
Holders in connection with any registration, qualification or compliance
effected pursuant to this Agreement, including without limitation all
registration, filing and qualification fees, printing expenses, fees and
disbursements of counsel for AROC and for the holders of Registrable Securities,
and the expenses of any audits required by such registration, shall be borne by
AROC and (b) in the case of Piggyback Registrations pursuant to Section 2 (other
than a primary registration by AROC), all of the incremental expenses incurred
by AROC (and not otherwise reimbursed) shall be borne by the holders of
Registrable Securities included in any registration pursuant to the terms
hereof; provided, however, that AROC shall not be required to pay: (i) the
underwriters' fees, discounts or commissions relating to Registrable Securities;
or (ii) the fees and disbursements of more than a single law firm for all
holders of Registrable Securities to be selected by the holders of a majority of
such Registrable Securities participating in a Requested Registration pursuant
to Section 3. Notwithstanding the foregoing, AROC shall not be required to pay
for any expenses of any registration proceeding begun pursuant to Section 3 if
the request for registration is subsequently withdrawn at the request of the
holders of a majority of the Registrable Securities to be registered therein
(which holders shall bear such expenses), unless the holders of a majority of
the Registrable Securities agree that such registration shall be deemed to
constitute a Requested Registration for purposes of the limitation set forth in
the proviso of Section 3.01(a)(ii); provided, however, that if (a) between the
date such request for registration is made and the date of such withdrawal,
there has occurred a material adverse change in the condition, business or
prospects of AROC (or a material adverse change occurring prior to such request
is first publicly disclosed) and (b) such withdrawal shall have occurred prior
to the effective date of the applicable registration statement (it being
understood that the holders shall only have the right to withdraw a Requested
Registration prior to such effective date), then the holders shall not be
required to pay any of such expenses and no Requested Registration shall be
deemed to have occurred pursuant to Section 3.

Section 5.  Registration Procedures.

5.01.  In the case of each registration, qualification or compliance effected by
AROC pursuant to this Agreement, AROC shall, by notice to each holder of
Registrable Securities included in such registration, keep such holder advised
in writing as to the initiation, progress and effective date of each
registration, qualification and compliance, and, at the expense of AROC, AROC
will:

     (a)  prepare and file with the Commission a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective as soon as reasonably practicable
thereafter; and before filing a registration statement or prospectus or any
amendments or supplements thereto, furnish to the Investor (provided Registrable
Securities held by the Investor are covered by such registration statement) and
the underwriter or underwriters, if any, copies of all such documents proposed
to be filed, including without limitation documents incorporated by reference in
the prospectus and, if requested by such holders of Registrable Securities, the
exhibits incorporated by reference, and such holders shall have the opportunity
to object to any information pertaining to such holders that is contained
therein and AROC will make the corrections reasonably requested by an

                                       7
<PAGE>

underwriter or such holders with respect to such information prior to filing any
registration statement or amendment thereto or any prospectus or any supplement
thereto;

     (b)  prepare and file with the Commission such amendments and supplements
to such registration statement and the prospectus used in connection therewith
as may be necessary to keep such registration statement effective for a period
(the "Effective Period") of not less than 180 days, or such shorter period as is
necessary to complete the distribution of the securities covered by such
registration statement and comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration
statement during such period in accordance with the intended methods of
disposition by the seller thereof set forth in such registration statement;

     (c)  furnish to each seller of Registrable Securities such number of copies
of such registration statement, each amendment and supplement thereto, the
prospectus included in such registration statement (including without limitation
each preliminary prospectus) and such other documents as such seller may
reasonably request in order to facilitate the disposition of the Registrable
Securities owned by such seller;

     (d)  use its best efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions as
any seller reasonably requests and take such other steps which may be necessary
or advisable in the reasonable judgment of the managing underwriter (and at the
reasonable request of such managing underwriter) to enable such seller to
consummate the disposition in such jurisdictions of the Registrable Securities
owned by such seller (provided that AROC will not for any such purpose be
required to (1) qualify generally to do business as a foreign corporation in any
jurisdiction where it would not otherwise be required to qualify but for the
requirements of this subsection; (2) subject itself to taxation in any such
jurisdiction; (3) consent to general service of process in any such
jurisdiction; or (4) register or qualify Registrable Securities or take any
other action under the state securities or "Blue Sky" laws of any jurisdiction
if, in the judgment of the Board of Directors of AROC, the consequences of the
registration, qualification or other action would be unduly burdensome to AROC).

     (e)  notify the Investor and each seller of such Registrable Securities
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the occurrence of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, at the request of any such seller, or at the request of any
seller upon the happening of any event of the kind described in Section 5.01(k),
AROC shall prepare a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable Securities, such
prospectus shall not contain an untrue statement of a material fact or omit to
state any fact necessary to make the statements therein not misleading or cures
the event of the kind described in Section 5.01(k);

     (f)  in the case of an underwritten offering, cause to be delivered to the
sellers of Registrable Securities and the underwriters, if any, opinions of
counsel to AROC in customary form, covering such matters as are customarily
covered by opinions for an underwritten public offering as the underwriters may
reasonably request and addressed to the underwriters and such sellers;

     (g)  make available for inspection by any seller of Registrable Securities
that is a Significant Holder, any underwriter participating in any disposition
pursuant to such registration statement, and any attorney, accountant or other
agent retained by any seller or underwriter, all financial and other records,

                                       8
<PAGE>

pertinent corporate documents and properties of AROC, and cause AROC's officers,
directors, employees and independent accountants to supply all information
reasonably requested by any such seller, underwriter, attorney, accountant or
agent in connection with such registration statement;

     (h)  provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

     (i)  cause to be delivered, immediately prior to the effectiveness of the
registration statement (and, in the case of an underwritten offering, at the
time of delivery of any Registrable Securities sold pursuant thereto), letters
from AROC's independent certified public accountants addressed to each seller
that is a Significant Holder and each underwriter, if any, stating that such
accountants are independent public accountants within the meaning of the
Securities Act and the applicable published rules and regulations thereunder,
and otherwise in customary form and covering such financial and accounting
matters as are customarily covered by letters of the independent certified
public accountants delivered in connection with primary or secondary
underwritten public offerings, as the case may be;

     (j)  make generally available to the holders of Registrable Securities a
consolidated earnings statement (which need not be audited) for the 12 months
beginning after the effective date of a registration statement as soon as
reasonably practicable after the end of such period, which earnings statement
shall satisfy Section 11(a) of the Securities Act and Rule 158 thereunder; and

     (k)  promptly notify the Investor and any Significant Holder selling
Registrable Securities in such registration and the underwriter or underwriters,
if any:

               (i)   when the registration statement, any preeffective
amendment, the prospectus or any prospectus supplement or post-effective
amendment to the registration statement has been filed and, with respect to the
registration statement or any post-effective amendment, when the same has become
effective;

               (ii)  of any written request by the Commission for post-effective
amendments or supplements to the registration statement or prospectus;

               (iii) of the notification to AROC by the Commission of its
initiation of any proceeding with respect to the issuance by the Commission of,
or the issuance by the Commission of, any stop order suspending the
effectiveness of the registration statement; and

               (iv)  of the receipt by AROC of any notification with respect to
the suspension of the qualification of any Registrable Securities for sale under
the applicable securities or blue sky laws of any jurisdiction.

5.02.  As soon as possible following receipt of notice from the Managing
Underwriter that a particular registration is a Cutback Registration, AROC will
notify the Investor and each of the holders of Registrable Securities that is a
Significant Holder requested to be included therein that such registration is a
Cutback Registration and of the effect thereof on the ability of such holders to
include their shares in such registration.

5.03.  AROC will use its best efforts to become (and thereafter to remain)
eligible to effect Short-Form Registrations.

                                       9
<PAGE>

5.04.  Whenever the holders of Registrable Securities have requested that any
Registrable Securities be registered pursuant to Section 2 or Section 3, each
holder of Registrable Securities will be deemed to have agreed that, upon
receipt of any notice from AROC of the happening of any event of the kind
described in Section 5.01(e) or Section 5.01(k)(ii) or (iii), the holders of
Registrable Securities covered by such registration statement will forthwith
discontinue disposition of any such Registrable Securities until the holders of
Registrable Securities receive copies of the supplemented or amended prospectus
contemplated by Section 5.01(e), or until they are advised in writing by AROC
that the use of the applicable prospectus may be resumed, and they have received
copies of any additional or supplemental filings that are incorporated or deemed
to be incorporated by reference in such prospectus (it being the agreement of
the parties hereto, however, that the obligation of AROC with respect to
maintaining the subject registration statement current and effective shall be
extended by a period of days equal to the period the holders of Registrable
Securities are required by this Section 5.04 to discontinue disposition of such
Registrable Securities.

Section 6. Indemnification; Contribution.

6.01.  With respect to any registration, qualification or compliance effected or
to be effected pursuant to this Agreement, AROC shall indemnify each holder of
Registrable Securities whose securities are included or are to be included
therein, each such holder's directors, officers, employees, stockholders,
Affiliates and agents, each underwriter (as defined in the Securities Act) of
the securities sold by such holder and each Person who controls (within the
meaning of the Securities Act) any such holder or underwriter, from and against
all claims, losses, damages and liabilities (or actions in respect thereof)
arising out of or based on:

       (i)   any untrue statement (or alleged untrue statement) of a material
fact contained in any prospectus, offering circular or other document (including
without limitation any related registration statement, notification or the
like), or any amendment thereof or supplement thereto, incident to any such
registration, qualification or compliance;

       (ii)  any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading; or

       (iii) any violation by AROC of the Securities Act, the Exchange Act or
any rule or regulation promulgated thereunder applicable to AROC, or of any blue
sky or other state securities laws or any rule or regulation promulgated
thereunder applicable to AROC,

and will reimburse each such Person entitled to indemnity under this Section
6.01 for all legal and other expenses reasonably incurred, as the same are
incurred, in connection with investigating or defending any such claim, loss,
damage, liability or action; provided, however, that the foregoing indemnity and
reimbursement obligation shall not be applicable to the extent that any such
claim, loss, damage or liability arises out of or is based on any untrue
statement (or alleged untrue statement) or omission (or alleged omission) or
violation made in reliance upon and in conformity with written information
furnished to AROC by such holder specifically for use in such prospectus,
offering circular, other document, amendment or supplement; and provided further
that the foregoing indemnity and reimbursement obligation shall not be
applicable with respect to any preliminary prospectus to the extent that any
loss, claim, damage, liability or expense of the indemnitee results from the
fact that a holder of Registrable Securities sold Registrable Securities to a
person to whom there was not sent or given, at or prior to the written
confirmation of the sale, a copy of the prospectus (excluding documents
incorporated by

                                       10
<PAGE>

reference) or of the prospectus as then amended or supplemented (excluding
documents incorporated by reference) if AROC has previously furnished copies
thereof to the holder of Registrable Securities in compliance with Section 5 of
this Agreement and the loss, claim, damage, liability or expense of the
indemnitee results from an untrue statement or omission of a material fact
contained in such preliminary prospectus which was corrected in the prospectus
(or the prospectus as amended or supplemented).

6.02.  With respect to any registration, qualification or compliance effected or
to be effected pursuant to this Agreement, each holder of Registrable Securities
which are included or are to be included in such registration, qualification or
compliance shall indemnify AROC, its directors, officers, employees,
stockholders, Affiliates and agents, each underwriter (as defined in the
Securities Act) of the securities of such holder, each Person who controls
(within the meaning of the Securities Act) AROC or any such underwriter from and
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on:

       (i)   any untrue statement (or alleged untrue statement) of a material
fact contained in any prospectus, offering circular or other document (including
without limitation any related registration statement, notification or the
like), or any amendment thereof or supplement thereto, incident to any such
registration, qualification or compliance;

       (ii)  any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading;

       (iii) any violation by such holder of the Securities Act, the Exchange
Act or any rule or regulation promulgated thereunder applicable to such holder,
or of any blue sky or other state securities law or any rule or regulation
promulgated thereunder applicable to such holder, and will reimburse each such
Person entitled to indemnity under this Section 6.02 for any legal and other
expenses reasonably incurred in connection with investigating or defending any
such claim, loss, damage, expense, liability or action; or

       (iv)  with respect to any preliminary prospectus, the fact that any
holder of Registrable Securities sold Registrable Securities to a person to whom
there was not sent or given, at or prior to the written confirmation of the
sale, a copy of the prospectus (excluding documents incorporated by reference)
or of the prospectus as then amended or supplemented (excluding documents
incorporated by reference) if (a) AROC has previously furnished copies thereof
to the holder of Registrable Securities in compliance with Section 5 of this
Agreement and (b) the loss, claim, damage, liability or expense of the
indemnitee results from an untrue statement or omission of a material fact
contained in the preliminary prospectus which was corrected in the prospectus
(or the prospectus as amended or supplemented);

but in each case of the preceding subsections (i), (ii), (iii) and (iv), only to
the extent that such untrue statement (or alleged untrue statement) or omission
(or alleged omission) or violation is made in such prospectus, offering
circular, other document, amendment or supplement in reliance upon and in
conformity with written information furnished to AROC by such holder
specifically for use in such prospectus, offering circular, other document,
amendment or supplement.

6.03.  Each Person entitled to indemnification under this Section 6 (an
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after the Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided, however, that:

                                       11
<PAGE>

     (i)   counsel for the Indemnifying Party who shall conduct the defense of
any such claim or any litigation shall be approved by the Indemnified Party
(which approval shall not be unreasonably withheld or delayed);

     (ii)  the Indemnified Party may participate in such defense at the
Indemnified Party's expense; provided, however, that the Indemnified Party or
Indemnified Parties shall have the right to employ a single law firm and a
single local counsel law firm to represent it or them if, in the reasonable
judgment of the Indemnified Party or Indemnified Parties, it is advisable for it
or them to be represented by separate counsel by reason of having legal defenses
which are different from or in addition to those available to the Indemnifying
Party, and in that event the reasonable fees and expenses of one such law firm
and one such local law firm shall be paid by the Indemnifying Party; and

     (iii) failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Section
6.

     No Indemnifying Party, in the defense of any such claim or litigation,
shall, except with the consent of the Indemnified Party to which such claim or
litigation relates, consent to entry of any judgment or enter into any
settlement unless such settlement relieves the Indemnified Party of any and all
liability.  Each Indemnified Party shall furnish such information regarding
itself for the claim in question as an Indemnifying Party may reasonably request
in writing and as shall be reasonably required in connection with defense of
such claim in litigation resulting therefrom.

6.04.  If the indemnity and reimbursement obligation provided for in each of
Section 6.01 and Section 6.02 is unavailable or insufficient to hold harmless an
Indemnified Party in respect of any claims, losses, damages or liabilities (or
actions in respect thereof) referred to therein, then the Indemnifying Party
shall contribute to the amount paid or payable by the Indemnified Party as a
result of such claims, losses, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party, on the one hand, and the Indemnified Party, on the other
hand, in connection with statements or omissions which resulted in such claims,
losses, damages or liabilities, as well as any other relevant equitable
considerations.  The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Indemnifying Party or the Indemnified Party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission.the parties hereto agree
that it would not be just and equitable if contributions pursuant to this
Section 6.04 were to be determined by pro rata allocation or by any other method
of allocation which does not take account of the equitable considerations
referred to in the first sentence of this Section 6.04. The amount paid by an
Indemnified Party as a result of the losses, claims, damages or liabilities
referred to in the first sentence of this Section 6.04 shall be deemed to
include any legal and other expenses reasonably incurred by such Indemnified
Party in connection with investigating or defending any claim, loss, damage,
liability or action which is the subject of this Section 6.04.

     No Indemnified Party guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from the Indemnifying Party if the Indemnifying Party was not
guilty of such fraudulent misrepresentation.

     The provisions of this Section 6 shall be in addition to any other rights
to indemnification or contribution which an indemnified party may have pursuant
to law, equity, contract or otherwise and shall

                                       12
<PAGE>

remain in full force and effect regardless of any investigation made by or on
behalf of an Indemnified Party and shall survive the transfer of the shares of
Common Stock or other stock or securities which may be issued upon exercise of
the Warrants.

Section 7.  Information by Holders.

     If Registrable Securities owned by a holder are included in any
registration, such holder shall furnish to AROC such information regarding
itself and the distribution proposed by such holder as AROC may reasonably
request and as shall otherwise be required in connection with any registration,
qualification or compliance referred to in this Agreement.

Section 8.  Rule 144 Reporting; Rule 144A Sales.

connection with the use of Rule 144 and take such other actions and furnish such
holder with such other public information as such holder may reasonably request
in order to assist such holder in availing itself of any rule or regulation of
the Commission allowing such holder to sell any Registrable Securities without
registration; and

     (b)  each holder of Registrable Securities and each prospective holder of
Registrable Securities who may consider acquiring Registrable Securities in
reliance upon Rule 144A shall have the right to request from AROC, and AROC will
provide upon request, such public information regarding AROC and its business,
assets and properties, if any, as such holder may reasonably request so as to
assist such holder in the transfer of Registrable Securities to such prospective
holder in reliance upon Rule 144A.

Section 9.  Other Registration Rights.

9.01.  AROC represents and warrants to the Investor that there is not in effect

other Registration Agreements) pursuant to which any holders of securities of

registration to be delivered by AROC to any holder of any

                                       13
<PAGE>

rights under any of the Registration Agreements to the Investor and any
Significant Holders of Registrable Securities.so long as any Registrable
Securities shall be outstanding, prior to the Expiration Date (as defined in the
Warrant) AROC shall not agree with the holders of any securities issued or to be
issued by AROC to register or qualify such securities under the Securities Act
or any applicable state securities laws unless such agreement (including any
Registration Agreement) specifically provides that: (a) such holder of such
securities may not participate in any Piggyback Registration except as provided
in Section 2; and (b) the holder of such securities may not participate in any
Requested Registration except as provided in Section 3.

Section 10.  Holdback Agreements. In order to facilitate the possibility of

Stock or securities convertible into or exercisable or exchangeable for its
Common Stock and continuing until the earlier of the abandonment of the proposed
public offering or 120 days following the date of the last closing in the public
offering without the consent of the underwriters of such offering, except to the
extent such shares are included in such registration.  Holders of such
Registrable Securities also agree that they will cooperate with AROC in
providing reasonable written assurances respecting the foregoing to the
underwriter of any such public offering.  Holders agree that during the above
restricted period they will not directly or indirectly sell, offer to sell,
contract to sell (including without limitation any short sale), grant an option

every other person subject to the foregoing restriction), until the end of the

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

Shareholders to be included in such Piggyback Registration pursuant to
subsection 2.1 and any other securities of the Corporation held by persons other
- --------------

Registration, pro rata among all such holders on the basis of the total number
of shares of securities of the Corporation, including Qualified Registrable
Securities, requested by each such holder to be included therein.

          -------------------------
underwritten offering, the Corporation will have the sole right to select the
managing underwriter(s) thereof.

     2.4. Relative Rights With Other Holders.  The rights of Selling Shareholder
          ----------------------------------
with respect to Piggyback Registrations shall be pari passu with the piggyback
registration rights of other holders of Common Equity Securities.

3.   Registration Procedures.  If and whenever the Corporation is required by
     -----------------------
the provisions of this Agreement to use its reasonable efforts to effect the
registration of any Qualified Registrable Securities:

     3.1. Covenants by Corporation.  The Corporation shall, as expeditiously as
          ------------------------
reasonably practicable:

          (i)   Prepare and file with the Commission under the Securities Act a
registration statement with respect to the Qualified Registrable Securities, and
use its reasonable efforts to cause such registration statement to become
effective and to remain effective as provided in this Agreement; provided,
                                                                 --------
however, that the Corporation may discontinue any registration of securities
- -------  ----
that is being effected pursuant to subsection 2.1 at any time prior to the
                                   --------------
effective date of the registration statement relating thereto.

          (ii)  Prepare and file with the Commission such amendments and
supplements, if any, to the registration statement and the prospectus included
in the registration statement as may be necessary to (a) keep the registration
statement effective until the earlier of 90 days after its effectiveness or the
completion of the distribution under the registration statement, and (b) comply
with the provisions of the Securities Act applicable to it with respect to the
disposition of all Qualified Registrable Securities covered by the registration
statement during that period in accordance with the intended methods of
disposition by the Selling Shareholders.

          (iii) Furnish to any Selling Shareholder participating in the
registration and the underwriter, if any, the number of copies of the
registration statement (including exhibits), each amendment and supplement
thereto, the prospectus included in the registration statement (including each
preliminary prospectus) and of each amendment and supplement thereto as the
Selling Shareholder and its underwriter may reasonably request in order to
facilitate the public disposition of the Qualified Registrable Securities owned
by the Selling Shareholder and included in the registration statement.

          (iv)  Use its reasonable efforts to (a) register or qualify the
Qualified Registrable Securities under the securities or blue sky laws of any
jurisdictions as any Selling Shareholder participating in the registration or
the underwriter reasonably requests, (b) keep the registration and qualification
in effect for so long as the registration statement is in effect, and (c) do any
and all other acts and things that may be reasonably necessary or advisable to
enable the Selling Shareholder to complete the disposition in such jurisdictions
of the relevant Qualified Registrable Securities (provided that the Corporation
                                                  -------- ----
will not for any such purpose be required to (1) qualify generally to do
business as a foreign corporation in any jurisdiction where it would not
otherwise be required to qualify but for the requirements of this subsection;
(2) subject itself to taxation in any such

                                       3
<PAGE>

jurisdiction; (3) consent to general service of process in any such
jurisdiction; or (4) register or qualify Qualified Registrable Securities or
take any other action under the state securities or "Blue Sky" laws of any
jurisdiction if, in the judgment of the Board of Directors of the Corporation,
the consequences of the registration, qualification or other action would be
unduly burdensome to the Corporation).

          (v)       At any time when a prospectus relating to the registration
statement is required to be delivered under the Securities Act, notify any
Selling Shareholder participating in the registration when it becomes aware of
the happening of any event as a result of which the prospectus (as then amended
or supplemented) contains any untrue statement of a material fact or omits any
fact necessary to make the statements therein in the light of the circumstances
under which they were made not misleading, and, at the request of the Selling
Shareholder, as promptly as practicable thereafter, prepare in sufficient
quantities and furnish to the Selling Shareholder and the underwriter a
reasonable number of copies of a prospectus supplemented or amended so that, as
thereafter delivered to the offerees or purchasers of the Qualified Registrable
Securities, the prospectus will not contain an untrue statement of a material
fact or omit to state any fact necessary to make the statements therein in light
of the circumstances then existing not misleading.

          (vi)      Comply with all applicable rules and regulations of the
Commission, and make generally available to its security holders, as soon as
reasonably practicable, an earnings statement covering the period of at least
twelve consecutive months beginning with the first day of the Corporation's
first calendar quarter after the effective date of the registration statement,
which earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act and Rule 158 thereunder.

          (vii)     Use its reasonable efforts to cause all Qualified
Registrable Securities covered by the registration statement to be listed on any
securities exchange, if any, on which similar securities issued by the
Corporation are then listed, if the listing of the Qualified Registrable
Securities is then permitted under the rules of the exchange.

          (viii)    Enter into customary agreements relating to the registration
(including an underwriting agreement in customary form if the registration is in
connection with an underwritten offering).

          (ix)      Subject to the execution of confidentiality agreements in a
form satisfactory to the Corporation, make reasonably available for inspection
by the Selling Shareholder, any underwriter participating in any disposition
pursuant to the registration statement and any legal counsel, accountant or
other agent retained by any underwriter, all financial and other records,
pertinent corporate documents and properties of the Corporation, and cause the
Corporation's directors, officers, employees, counsel and independent public
accountants to supply all information reasonably requested by, and to respond to
inquiries from, the Selling Shareholder, any such underwriter, legal counsel,
attorney, accountant or agent in connection with such registration statement, in
each case, to the extent that information is reasonably necessary to satisfy any
of its obligations under applicable law.

          (x)       Use reasonable efforts to obtain an appropriate opinion from
counsel for the Corporation and a "cold comfort" letter from the Corporation's
independent public accountants, each

                                       4
<PAGE>

in customary form and covering matters of the type customarily covered by
opinions of counsel and cold comfort letters in similar registrations; provided,
                                                                       --------
however, that failure to provide such opinion or letter, or the provision of any
- -------  ----
such opinion or letter in a form not satisfactory to the Selling Shareholders,
notwithstanding the Corporation's reasonable efforts, shall not give rise to any
action, at law or in equity, for damages or injunctive or other relief, but
rather shall only entitle the Selling Shareholders to withdraw its Qualified
Registrable Securities from the registration statement, pursuant to subsection
                                                                    ----------
3.3 below.
- ---

          (xi)    Provide (a) any Selling Shareholder participating in the
registration, (b) the underwriter or underwriters (which term, for purposes of
this Agreement, shall include any person deemed to be an underwriter within the
meaning of Section 2(11) of the Securities Act), if any, of the securities being
sold, and (c) counsel for the underwriters the opportunity to participate in the
preparation of the registration statement, each prospectus included therein or
filed with the Commission, and each amendment or supplement thereto.

          (xii)   Promptly notify any Selling Shareholder participating in the
registration and the underwriter, if any, and (if requested by any such person)
confirm the advice in writing, (a) when the registration statement, the
prospectus or any prospectus supplement or post-effective amendment has been
filed, and, when the registration statement or any post-effective amendment
thereto has become effective, (b) of the issuance by the Commission of any stop
order suspending the effectiveness of the registration statement or the
initiation of any proceedings for that purpose, or (c) of the receipt by the
Corporation of any notification with respect to the suspension of the
qualification of the Qualified Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for that
purpose.

          (xiii)  Use its reasonable efforts to obtain the withdrawal of any
order suspending the effectiveness of a registration statement hereunder or any
post-effective amendment thereto at the earliest practicable date.

          (xiv)   Notify in writing the Selling Shareholders of any proposal
by the Corporation to amend or waive any provision of this Agreement pursuant to
subsections 8.2 and 8.3 and of any amendment or waiver effected pursuant to
- ---------------     ---
those subsections, each of which notices shall contain the text of the amendment
or waiver proposed or effected, as the case may be.

     3.2. Certain Agreements by the Selling Shareholders.
          ----------------------------------------------

          (i)     Each of the Selling Shareholders agrees that upon receipt of
any notice from the Corporation of the happening of any event of the kind
described in subsection 3.1(v), the Selling Shareholder will immediately
             -----------------
discontinue its disposition of Qualified Registrable Securities pursuant to the
registration statement covering its Qualified Registrable Securities until its
receipt of the copies of the supplemented or amended prospectus contemplated by
subsection 3.1(v) and, if so directed by the Corporation, will deliver to the
- -----------------
Corporation (at the Corporation's expense) all copies, other than permanent file
copies, then in its possession of the prospectus covering the Qualified
Registrable Securities that was in effect at the time of receipt of the notice.
If the Corporation gives any such notice, the period mentioned in subsection
                                                                  ----------
3.1(ii)(a)(1) shall be extended by the number of days during the period from and
- -------------
including the date of the giving of the notice to and including the date

                                       5
<PAGE>

when Selling Shareholder receives the copies of the supplemented or amended
prospectus contemplated by subsection 3.1(v).
                           -----------------

          (ii) Each of the Selling Shareholders agrees that upon receipt of a
notice from the Corporation that it has filed and caused to become effective a
registration statement that includes an offering of Common Equity Securities for
sale by the Corporation to the public in an underwritten public offering, if the
Selling Shareholder was given the opportunity to include its Qualified
Registrable Securities for sale in the public offering, the Selling Shareholder
shall enter into agreements with the underwriters of the public offering,
substantially in the same form as agreements entered into by the officers and
directors of the Corporation, precluding the sale of Common Stock by the Selling
Shareholder for a period not to exceed 180 days following the notice.

     3.3. Withdrawal.  If any Selling Shareholder disapproves of the terms of
          ----------
any offering, the Selling Shareholder's sole remedy shall be, at its sole
discretion, to withdraw its Qualified Registrable Securities and other
securities of the Corporation from the offering by written notice to the
Corporation and the underwriter (if any); and the Selling Shareholder's
Qualified Registrable Securities and other securities of the Corporation
withdrawn from the offering will also be withdrawn from registration.

     3.4. Information.  The Corporation may require each Selling Shareholder to
          ------------
furnish the Corporation such information regarding the Selling Shareholder and
the distribution of its securities as the Corporation may from time to time
reasonably request in writing for purposes of preparation of the registration
statement, to the extent that the information is required to comply with
applicable legal requirements.

4.   Registration Expenses.
     ---------------------

     4.1. Responsibility for Payment.  Whether or not any registration pursuant
          --------------------------
to this Agreement becomes effective, all expenses incident to the Corporation's
performance of or compliance with this Agreement, including without limitation
all registration and filing fees, National Association of Securities Dealers'
fees, fees and expenses of compliance with state securities or blue sky laws,
printing and engraving expenses and fees and disbursements of counsel for the
Corporation and the independent certified public accountants for the
Corporation, underwriters (excluding discounts, commissions and transfer taxes
attributable to securities offered by the Selling Shareholders and amounts to be
borne by the underwriters) and other persons retained by the Corporation (all
such expenses being herein called "Corporation Registration Expenses"), will be
                                   ---------------------------------
borne by the Corporation,  and all expenses incident to the Selling
Shareholders' performance of or compliance with this Agreement, including
without limitation all fees and disbursements of counsel for the Selling
Shareholders and the discounts, commissions and transfer taxes attributable to
securities offered by the Selling Shareholders, will be borne by the Selling
Shareholders; provided, however, that (i) if the Selling Shareholders are
              --------  -------  ----
required to pay any Registration Expenses as provided in subsection 4.2, then
                                                         --------------
the Selling Shareholders shall pay the Registration Expenses in the proportion
to (a) the number of shares of Qualified Registrable Securities requested to be
registered by the Selling Shareholder in the registration statement if the
registration does not become effective, or (b) the number of shares of Qualified
Registrable Securities of the Selling Shareholder included in the registration
statement, if the registration statement becomes effective, unless in either
case

                                       6
<PAGE>

another basis of sharing the Registration Expenses is required under applicable
laws, rules or regulations, in which case such other method shall apply; and
(ii) the Selling Shareholder shall pay any underwriting discounts and selling
commissions and transfer taxes applicable to Qualified Registrable Securities
sold by Selling Shareholder.

     4.2. Legal Requirements.  Notwithstanding anything herein to the contrary,
          ------------------
Selling Shareholder shall pay the Registration Expenses to the extent required
by applicable law.

5.   Indemnification.
     ---------------

     5.1. Indemnification by the Corporation.  The Corporation agrees to
          ----------------------------------
indemnify and hold harmless, to the full extent permitted by law, each Selling
Shareholder, its directors, officers, employees and agents (and the directors,
officers, employees and agents thereof) and each other person or entity who
controls the Selling Shareholder within the meaning of the Securities Act
(collectively, the "Selling Shareholder Indemnitees" and individually a "Selling
                    ------- -----------------------                      -------
Shareholder Indemnitee") against all losses, claims, damages, liabilities and
- ----------------------
expenses, joint or several (including reasonable fees of counsel and any amounts
paid in settlement effected with the Corporation's consent, which consent shall
not be unreasonably withheld), to which any such Selling Shareholder Indemnitee
may become subject under the Securities Act, at common law or otherwise, insofar
as such losses, claims, damages, liabilities or expenses (or actions or
proceedings, whether commenced or threatened, in respect thereof), are caused by
(i) any untrue statement or alleged untrue statement of a material fact
contained in any registration statement in which such Qualified Registrable
Securities were included or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, (ii) any untrue statement or alleged untrue statement of
a material fact contained in any preliminary, final or summary prospectus,
together with the documents incorporated by reference therein (as amended or
supplemented if the Corporation shall have filed with the Commission any
amendment or supplement), or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein in the light of the circumstances under which they were made
not misleading, or (iii) any violation by the Corporation of any federal, state
or common law rule or regulation applicable to the Corporation and relating to
action of or inaction by the Corporation in connection with any registration
statement; and in each case the Corporation will reimburse each Selling
Shareholder Indemnitee for any reasonable legal or any other expenses incurred
by any of them in connection with investigating or defending any such loss,
claim, damage, liability, expense, action or proceeding; provided, that the
                                                         --------  ----
Corporation shall not be liable to any such Selling Shareholder Indemnitee in
any case to the extent that any loss, claim, damage, liability or expense (or
action or proceeding, whether commenced or threatened, in respect thereof)
arises out of or is based upon any untrue statement or alleged untrue statement
or omission or alleged omission made in the registration statement or amendment
or supplement or in any such preliminary, final or summary prospectus in
reliance upon and in conformity with written information furnished to the
Corporation by or on behalf of any Selling Shareholder relating to a Selling
Shareholder for use in the preparation thereof; and provided further that the
                                                    -------- ------- ----
Corporation shall not be liable to any Selling Shareholder Indemnitee with
respect to any preliminary prospectus to the extent that any loss, claim,
damage, liability or expense of the Selling Shareholder Indemnitee results from
the fact that a Selling Shareholder sold Qualified Registrable Securities to a
person to whom there was not sent or given, at or prior to the written
confirmation of the sale, a copy of the prospectus (excluding documents

                                       7
<PAGE>

incorporated by reference) or of the prospectus as then amended or supplemented
(excluding documents incorporated by reference) if the Corporation has
previously furnished copies thereof to the Selling Shareholder in compliance
with Section 3 of this Agreement and the loss, claim, damage, liability or
     ---------
expense of the Selling Shareholder Indemnitee results from an untrue statement
or omission of a material fact contained in such preliminary prospectus which
was corrected in the prospectus (or the prospectus as amended or supplemented).
Such indemnity and reimbursement of expenses shall remain in full force and
effect regardless of any investigation made by or on behalf of any Selling
Shareholder and shall survive the transfer of such securities by any Selling
Shareholder.

     5.2. Indemnification by the Selling Shareholders.  Each Selling Shareholder
          -------------------------------------------
agrees, jointly and severally, to indemnify and hold harmless, to the fullest
extent permitted by law, the Corporation, its directors, officers, employees and
agents and each Person who controls the Corporation (within the meaning of the
Securities Act) (collectively, the "Corporation Indemnitees" and individually a
                                    -----------------------
"Corporation Indemnitee") against all losses, claims, damages, liabilities and
 ----------------------
expenses, joint or several (including reasonable fees of counsel and any amounts
paid in settlement effected with any Selling Shareholder's consent, which
consent shall not be unreasonably withheld) to which any Corporation Indemnitee
may become subject under the Securities Act, at common law or otherwise insofar
as such losses, claims, damages, liabilities or expenses (or actions or
proceedings, whether commenced or threatened, in respect thereof) are caused by
(i) any untrue statement or alleged untrue statement of a material fact
contained in any registration statement in which any of the Qualified
Registrable Securities were included or the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, (ii) any untrue statement or alleged
untrue statement of a material fact contained in any preliminary, final or
summary prospectus, together with the documents incorporated by reference
therein (as amended or supplemented if the Corporation shall have filed with the
Commission any amendment thereof or supplement thereto), or the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary in order to make the statements therein in the light of the
circumstances under which they were made not misleading to the extent, but only
to the extent, in the cases described in clauses (i) and (ii), that such untrue
statement or omission is contained in any information furnished in writing by
any Selling Shareholder relating to any Selling Shareholder for use in the
preparation thereof and if the Corporation does not know, at the time the
information is included in the registration statement, prospectus, preliminary
prospectus, amendment or supplement, that the information is false or
misleading, (iii) any violation by any Selling Shareholder of any federal, state
or common law, rule or regulation applicable to any Selling Shareholder and
relating to action of or inaction by any Selling Shareholder in connection with
any registration statement, and (iv) with respect to any preliminary prospectus,
the fact that any Selling Shareholder sold Qualified Registrable Securities to a
person to whom there was not sent or given, at or prior to the written
confirmation of the sale, a copy of the prospectus (excluding documents
incorporated by reference) or of the prospectus as then amended or supplemented
(excluding documents incorporated by reference) if (a) the Corporation has
previously furnished copies thereof to the Selling Shareholder in compliance
with Section 3 of this Agreement and (b) the loss, claim, damage, liability or
     ---------
expense of the Corporation Indemnitee results from an untrue statement or
omission of a material fact contained in the preliminary prospectus which was
corrected in the prospectus (or the prospectus as amended or supplemented).
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Corporation (except as provided above)
or any Selling Shareholder and shall survive the transfer of the securities by
any Selling Shareholder.

                                       8
<PAGE>

     5.3. Conduct of Indemnification Proceedings.  Promptly after receipt by an
          --------------------------------------
indemnified party under subsection 5.1 or 5.2 above of written notice of the
                        --------------    ---
commencement of any action, suit, proceeding, investigation or threat thereof
made in writing with respect to which a claim for indemnification may be made
pursuant to this Section 5, the indemnified party shall, if a claim in respect
                 ---------
thereto is to be made against an indemnifying party, give written notice to the
indemnifying party of the threat or commencement thereof; but the failure to
notify the indemnifying party shall not relieve it from any liability that it
may have to any indemnified party except to the extent that the indemnifying
party is actually prejudiced by the failure to give notice.  In case any such
claim or action referred to under subsections 5.1 or 5.2 shall be brought
                                  ---------------    ---
against any indemnified party and it shall notify the indemnifying party of the
threat or commencement thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any
other indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to the indemnified party (who shall not, except
with the consent of the indemnified party, be counsel to the indemnifying
party).  After notice from the indemnifying party to such indemnified party of
its election so to assume the defense of any such claim or action, the
indemnifying party shall not be liable to such indemnified party under this

Section 5 for any legal expenses of counsel or any other expenses subsequently
- ---------
incurred by such indemnified party in connection with the defense thereof other
than reasonable costs of investigation unless the indemnifying party has failed
to assume the defense of such claim or action or to employ counsel reasonably
satisfactory to such indemnified party.  The indemnifying party shall not be
required to indemnify the indemnified party with respect to any amounts paid in
settlement of any action, proceeding or investigation entered into without the
written consent of the indemnifying party which consent shall not be
unreasonably withheld.  No indemnifying party will consent to the entry of any
judgment or enter into any settlement without the consent of the indemnified
party, unless (i) such judgment or settlement does not impose any obligation or
liability upon the indemnified party other than the execution, delivery or
approval thereof, and (ii) such judgment or settlement includes as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect of such claim for
all persons that may be entitled to or obligated to provide indemnification or
contribution under this Section 5.
                        ---------

     5.4. Additional Indemnification.  Indemnification similar to that specified
          --------------------------
in the preceding subsections of this Section 5 (with appropriate modifications)
                                     ---------
shall be given by the Corporation and the Selling Shareholders with respect to
any required registration or other qualification of securities under any state
securities or blue sky laws.

     5.5. Contribution.  If the indemnification provided for in this Section 5
          ------------                                               ---------
is unavailable to or insufficient to hold harmless an indemnified party under

subsections 5.1 or 5.2 above, then each indemnifying party shall contribute to
- ---------------    ---
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages, liabilities or expenses (or actions in respect thereof)
referred to in subsections 5.1 or 5.2 in such proportion as is appropriate to
               ---------------    ---
reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other in connection with the statements, omissions,
actions or inactions which resulted in such losses, claims, damages, liabilities
or expenses.  The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party, any action or
inaction by any such

                                       9
<PAGE>

party and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement, omission, action or inaction.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or expenses (or actions in respect thereof)
referred to above in this subsection 5.5 shall be deemed to include any
                          --------------
reasonable legal or other expenses incurred by such indemnified party in
connection with investigating or defending any such action or claim (which shall
be limited as provided in subsection 5.3 if the indemnifying party has assumed
                          --------------
the defense of any such action in accordance with the provisions thereof) which
is the subject of this subsection 5.5. No person guilty of fraudulent
                       --------------
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. Promptly after receipt by an indemnified party
under this subsection 5.5 of written notice of the commencement of any action,
           --------------
suit, proceeding, investigation or threat thereof made in writing with respect
to which a claim for contribution may be made against an indemnifying party
under this subsection 5.5, such indemnified party shall, if a claim for
           --------------
contribution in respect thereto is to be made against an indemnifying party,
give written notice to the indemnifying party in writing of the commencement
thereof (if the notice specified in subsection 5.3 has not been given with
                                    --------------
respect to such action); but the failure to so to notify the indemnifying party
shall not relieve it from any obligation to provide contribution that it may
have to any indemnified party under this subsection 5.5 except to the extent
                                         --------------
that the indemnifying party is actually prejudiced by the failure to give
notice. Notwithstanding anything in this subsection 5.5 to the contrary, no
                                         --------------
indemnifying party (other than the Corporation) shall be required pursuant to
this subsection 5.5 to contribute any amount that exceeds the amount by which
     --------------
the dollar amount of the proceeds received by such indemnifying party from the
sale of Qualified Registrable Securities and other securities of the Corporation
(after deducting any underwriting commissions, discounts and transfer taxes
applicable thereto) in the offering to which the losses, claims, damages,
liabilities or expenses of the indemnified parties relate exceeds the amount of
any losses, claims, damages, liabilities and expenses that the indemnifying
party has otherwise been required to pay as indemnity or contribution hereunder
by reason of such losses, claims, damages, liabilities or expenses.

shall be in addition to any other rights to indemnification or contribution that
any indemnified party may have pursuant to law or contract and shall remain in
full force and effect regardless of any investigation made by or on behalf of
any indemnified party and shall survive the transfer of securities by any such
party.

     5.6. Indemnification and Contribution of Underwriters.  In connection with
          ------------------------------------------------
any underwritten offering contemplated by this Agreement which includes a
Selling Shareholder's Qualified Registrable Securities, the Corporation and the
Selling Shareholder will agree to customary provisions for indemnification and
contribution (consistent with the other provisions of this Section 5) in respect
                                                           ---------

Securities to be included in such registration shall be subject to the
underwriting agreement, which shall be in customary form and contain such terms
as are customarily contained in such agreements, and the Selling Shareholders

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

<PAGE>

1999 among American Rivers Oil Company, a Delaware corporation ("the Company"),
Alliance Resources Plc, a public limited company formed under the laws of
England and Wales ("Alliance"), and those persons identified on the signature

                                   Recitals

     The Warrant Holders hold warrants (the "Alliance Warrants") of Alliance
pursuant to Warrant Instruments of Alliance dated May 1, 1997 and October 30,
1998.

things for the Company to offer (the "Offer") to acquire all of the outstanding
ordinary shares of Alliance.

     One of the conditions to the completion of the Exchange and Merger
Agreement is that the Company shall enter into agreements with the holders of
the Alliance Warrants, on terms satisfactory to Alliance, providing that after
the Offer becomes unconditional each then outstanding Alliance Warrant shall be
exchanged for the right to receive warrants of the Company having terms
substantially similar to the terms of the Alliance Warrants.

Alliance Warrants for similar warrants of the Company.

     E.   Any provision of this Agreement that is prohibited or unenforceable in
          any jurisdiction shall, in such jurisdiction, be ineffective to the
          extent of such prohibition or unenforceability without invalidating
          the remaining provisions hereof, and any such prohibition or
          unenforceability in any jurisdiction shall not invalidate or render
          unenforceable such provision in any other jurisdiction.

          writing by, or on behalf of, all parties to this Agreement.  No waiver
          of any of the provisions of this Agreement will be deemed or will
          constitute a waiver of any other provision of this Agreement

                                   SCHEDULE

1.   Subscription Rights

     (a)  A registered holder (a "holder") of a Warrant shall have the right,
          exercisable in accordance with paragraph 1(c) below, to subscribe (the
          "subscription rights") in cash on any date prior to the Expiration
          Date in respect of such Warrant, on the following terms: for each
          Warrant specified in the Warrant certificate one share of Common Stock
          at the Subscription Price in respect of such Warrant payable in full
          on subscription. The number of shares of Common Stock to be subscribed
          and the subscription price are subject to adjustment pursuant to
          paragraph 2 below. The subscription rights will not be exercisable in
          respect of a fraction of a share of Common Stock. Failure to exercise
          a Warrant prior to 5:00 p.m. (Tulsa, Oklahoma time) on the relative
          Expiration Date will mean that the Warrant shall become void and all
          rights attaching to such Warrant shall cease.

     (b)  The number of Warrants to which each registered holder of Warrants
          shall be entitled shall be evidenced by a Warrant certificate issued
          by the Company. Warrant certificates shall be dated as of the date of
          issue, whether on initial issue, transfer, exchange or in lieu of
          mutilated, lost, stolen or destroyed Warrant certificates. Warrants
          shall be deemed to have been exercised immediately prior to the close
          of business on the date of the surrender for exercise of the Warrant
          certificate.

     (c)  In order to exercise the subscription rights in respect of any
          Warrants, the registered Warrant Holder must, after completing the
          notice of exercise on his Warrant certificate, deliver it to the
          office of the Warrant Agent for the Company accompanied by a
          remittance for the total subscription price of the shares of Common
          Stock in respect of which the subscription rights are being exercised.
          Once delivered, a notice of subscription shall be irrevocable except
          with the consent of the Directors of the Company.

     (d)  Shares of Common Stock issued pursuant to the exercise of subscription
          rights will be issued not later than 14 days after, and with effect
          from, the date on which the related duly completed subscription notice
          shall be delivered to the Warrant Agent for the Company (the
          "subscription date") and Common Stock certificates in respect of such
          shares of Common Stock will be issued free of charge and mailed (at
          the risk of the persons entitled thereto) not later than 14 days after
          the relevant subscription date to the first named person in whose name
          the Warrants are registered at the relevant subscription date or
          (subject as provided by law) to such other persons as may be named in
          the form of nomination upon the reverse of the Warrant certificate. In
          the event that not all of the Warrants evidenced by a Warrant
          certificate are exercised, the Company shall at the same time issue
          for no payment a fresh Warrant certificate in the name of the Warrant
          Holder for any balance of the subscription rights remaining
          exercisable.

     (e)  Shares of Common Stock issued pursuant to the exercise of subscription
          rights will not be deemed outstanding for any dividends or other
          distributions declared, made or paid in respect of any financial year
          of the Company prior to the financial year in which the relevant
          subscription date falls, nor shall they be deemed outstanding for any
          dividends or other distributions declared, made or paid on a date (or
          by reference to a record date) prior to the relevant subscription date
          but, subject thereto, will be treated pari passu in all other respects
          with the shares of Common Stock issued at the relevant subscription
          date including being deemed issued for all dividends and other
          distributions in respect of the financial year in which the relevant
          subscription date occurs provided that on any issuance failing to be
          made

                                       1
<PAGE>

          pursuant to paragraph 3(c) or 3(d) below the shares of Common Stock so
          to be issued shall not be deemed outstanding for any dividends or
          other distributions declared, made or paid by reference to a record
          date prior to the date of issuance.

     (f)  To the extent not then exercised, all subscription rights in respect
          of any Series of Warrants shall lapse at 5:00 p.m. (Tulsa, Oklahoma
          time) on the Expiration Date in respect of such Warrants.

     (g)  No sale, offering or transfer of any Series of Warrants or the shares
          underlying any Series of Warrants is permitted unless validly
          registered under the Securities Act of 1933, as amended, or exempt
          from the registration requirements of that Act.

2.   Adjustment of Subscription Price

     (a)  If, on a date (or by reference to a record date) on or before the
          relative Expiration Date in respect of a Warrant, the Company shall
          issue any Common Stock by way of dividend to holders of Common Stock
          of record on a date (or by reference to a record date) before the
          relative Expiration Date or upon any consolidation or sub-division of
          the Common Stock before such Expiration Date, the number of shares of
          Common Stock to be issued on any subsequent exercise of the
          subscription rights in respect of that Warrant will be increased or,
          as the case may be, reduced in due proportion and the subscription
          price per share of Common Stock will be adjusted accordingly. On any
          such dividend, consolidation or sub-division the Company will cause
          the auditors of the Company to verify the correctness of the
          appropriate adjustments and, within 28 days of such adjustments,
          notice will be sent to each Warrant Holder of the adjusted number of
          shares of Common Stock to which the Warrant Holder is entitled to
          subscribe in consequence thereof, fractional entitlements being
          ignored, such notice being accompanied by a new Warrant certificate in
          respect of such adjusted number of shares of Common Stock.

     (b)  If, on a date (or by reference to a record date) on or before the
          relative Expiration Date, the Company makes any offer or invitation
          (whether by rights issue, rights offer or otherwise but not being an
          offer to which paragraph 3(c) below applies or an offer of shares in
          lieu of a cash dividend payment) to the holders of Common Stock in
          their capacity as such, or any offer or invitation (not being an offer
          to which paragraph 3(d) below applies) is made to such holders
          otherwise than by the Company, then the Company shall, as far as it is
          able, cause at the same time the same offer or invitation to be made
          to the then Warrant Holders as if their subscription rights had been
          exercisable and had been exercised on the day immediately preceding
          the date (or record date) of such offer or invitation on the terms
          (subject to any adjustment pursuant to paragraph 2(a) above) on which
          the same could have been exercised on the basis then applicable
          provided that, if the Directors shall so resolve, in the case of any
          offer or invitation made by the Company, the Company shall not be
          required to cause the same offer or invitation to be made to the
          Warrant Holders but the subscription price and/or the number of shares
          of Common Stock to be subscribed on any subsequent exercise of the
          subscription rights shall be adjusted accordingly. The Company will
          cause the auditors of the Company to certify in writing the
          appropriateness of the adjustments and, within 28 days, notice will be
          sent to each Warrant Holder together with a new Warrant certificate in
          respect of the adjusted number of share of Common Stock to which that
          Warrant Holder is entitled to subscribe in consequence thereof,
          fractional entitlements being ignored.

     (c)  No adjustment shall be made to the subscription price of a Series of
          Warrants pursuant to paragraph 2(a) or (b) if such adjustment would
          (taken together with the amount of any

                                       2
<PAGE>

          adjustment carried forward under the provisions of this paragraph
          2(c)) be less than 1 percent of the relative subscription price then
          in force and on any adjustment the adjusted subscription price will be
          rounded down to the nearest $0.01. Any adjustment not so made and any
          amount by which the subscription price is rounded down will be carried
          forward and taken into account in any subsequent adjustment.

3.   Other Provisions

     So long as any subscription rights remain exercisable:

     (a)  the Company shall reserve for issuance sufficient authorized but
          unissued shares to satisfy in full (without the need for the passing
          of any resolution by shareholders) all subscription rights remaining
          exercisable;

     (b)  the Company shall not (except with the consent of the holders of at
          least three-fourths of the Warrants of each Series) issue any Common
          Stock by way of a dividend nor make any such offer as is referred to
          in paragraph 2(b) above if as a result the Company would on any
          subsequent exercise of the subscription rights be obliged to issue
          Common Stock for less than the par value thereof.

     (c)  if at any time an offer or invitation is made by the Company to the
          holders of Common Stock for the purchase by the Company of any of its
          Common Stock, the Company shall simultaneously give notice thereof to
          the Warrant Holders and each such Warrant Holder shall be entitled at
          any time while such offer or invitation is open for acceptance to
          exercise his subscription rights as if they were then exercisable so
          as to take effect as if he had exercised his rights immediately prior
          to the date (or record date) of such offer or invitation;

     (d)  if at any time an offer is made to all holders of Common Stock (or all
          holders of Common Stock other than the offeror and/or any company
          controlled by the offeror and/or persons acting in concert with the
          offeror) to acquire all or any part of the issued shares of the
          Company and the Company becomes aware that as a result of such offer
          the right to cast a majority of the votes which may ordinarily be cast
          on a vote at a meeting of the shareholders of the Company has or will
          become vested in the offeror and/or such persons or companies as
          aforesaid, the Company shall give notice to the Warrant Holders of
          such vesting within 14 days of its becoming so aware, and each such
          Warrant Holder shall be entitled, at any time within the period of 60
          days immediately following the date of such notice, to exercise his
          subscription rights as if they were exercisable on the last day of the
          said 60 day period on the basis (subject to any adjustment pursuant to
          paragraph 2 above) then applicable. Upon the expiry of such period,
          all Warrants shall lapse. Publication of a tender offer providing for
          the acquisition by any person of all or any part of the issued shares
          of the Company shall be deemed to be the making of an offer for the
          purposes of this paragraph 3(d);

     (e)  if the Company commences liquidation, whether voluntary or compulsory
          (except on terms sanctioned by the consent of the holders of at least
          three-fourths of the Warrants), it shall forthwith give notice thereof
          to all holders of Warrants; thereupon each Warrant shall be
          exercisable and each holder of a Warrant will (if in such winding-up
          there shall be a surplus available for distribution among the holders
          of Common Stock (including for this purpose the Common Stock which
          would be issued on the exercise of all the outstanding subscription
          rights) which, taking into account the amounts payable on the exercise
          of the subscription rights, exceeds in respect of each share of Common
          Stock a sum equal to the subscription price) be deemed, as of
          immediately before the date of such order or resolution, to have

                                       3
<PAGE>

          exercised his subscription rights in full and shall accordingly be
          entitled to receive out of the assets available on liquidation pari
          passu with the holders of the Common Stock such a sum as he is
          entitled as a holder of Common Stock to which he becomes entitled by
          virtue of such subscription after deducting a sum per share equal to
          the subscription price; subject to the foregoing, all subscription
          rights shall lapse on liquidation of the Company; and

     (f)  the Company shall not (except with the consent of the holders of at
          least three-fourths of the Warrants of each Series) issue Common Stock
          by way of a dividend unless at the date of such issuance the Directors
          have authority to grant the additional rights to subscribe to which
          the Warrant Holders will by virtue of paragraph 2(a) above to be
          entitled in consequence of such capitalization.

4.   Modification of Rights and Warrant Instrument

     All or any of the rights attached to the Warrants may from time to time
     (whether or not the Company is being wound up) be altered or abrogated with
     the consent of the holders of at least three-fourths of the Warrants of
     each Series affected by such alteration or abrogation.  Such alteration or
     abrogation approved as aforesaid shall be effected by a majority vote of
     the Board of Directors executed by the Company and expressed to be
     supplemental to this Warrant Instrument. Modifications to this Warrant
     Instrument which are of a formal, minor or technical nature, or made to
     correct a manifest error, or any modifications which the Directors consider
     appropriate may be effected by a majority vote of the Board of Directors
     executed by the Company and expressed to be supplemental to this Warrant
     Instrument and notice of such alteration or abrogation or modification
     shall be given by the Company to the Warrant Holders.

5.   Purchase by the Company

     The Company shall be entitled at any time to purchase Warrants on the open
     market or otherwise. Any Warrants so purchased shall be canceled
     immediately and shall not be available for re-issue.

6.   Transfer

     (a)  The Warrants will be registered and transferable in whole or in part
          by instrument of transfer in any usual or common form or in any other
          form which may be approved by the Directors except that no transfer of
          a right to subscribe for a fraction of a share of Common Stock shall
          be effected. Except insofar as the same would be inconsistent with
          this Warrant Instrument, the provisions of the Bylaws of the Company
          relating to the registration, transfer and transmission of shares
          shall apply mutatis mutandis to the Warrants.

     (b)  Notwithstanding any other provision contained herein, for so long as
          any Regulated Entity (as defined herein) holds any Series "G" Warrants
          or Series "H" Warrants which, upon exercise, would result in such
          Regulated Entity holding more than 5% of the outstanding Common Stock,
          such Regulated Entity may only transfer the Series "G" Warrants or
          Series "H" Warrants under the following circumstances:  (i) in a
          widely distributed public offering; (ii) in a transfer pursuant to
          Rule 144 under the United States of America ("U.S.") Securities Act of
          1933, as amended, or any similar rule then in force; (iii) in a
          transfer where the Common Stock underlying the Warrants being
          transferred represent two percent or less of the outstanding Common
          Stock (not including the transfer from the Regulated Entity); (v) in a
          transfer to the Company; (vi) in a transfer to an affiliate or such
          holder or any other Regulated Entity; or (vii) in any method of
          transfer permitted by the Board of Governors of the Federal Reserve
          System of the U.S.

                                  4
<PAGE>

          Once such Regulated Entity holds Warrants and share of Common Stock
          which, after exercise of the Warrants, would constitute 5.0% or less
          of the outstanding Common Stock, the foregoing restrictions on
          transfer shall cease to apply.

          "Regulated Entity" means (i) any entity that is a "bank holding
          company" (as defined in Section 2(a) of the U.S. Bank Holding Company
          Act of 1956, as amended (the "BHC Act")) or any non-bank subsidiary of
          such an entity or (ii) any entity that, pursuant to Section 8(a) of
          the U.S. International Banking Act of 1978, as amended, is subject to

          entity.

7.   Indemnification of Warrant Agent

     (a)  The Warrant Agent shall act as Agent of the Company. The Warrant Agent
          shall not, by issuing and delivering Warrant certificates or by any
          other act, be deemed to make any representations as to the validity or
          value of the Warrant certificates or the Warrants represented thereby
          or of the Common Stock or other property delivered on exercise of any
          Warrant. The Warrant Agent shall not be under any duty or
          responsibility to any holder of the Warrant certificates to make or
          cause to be made any adjustment of the Subscription Price or to
          determine whether any fact exists which may require any such
          adjustments.

     (b)  The Warrant Agent shall not (i) be liable for any statement or fact
          contained in this instrument or for any action taken or omitted by it
          in reliance on any Warrant certificate or other document or instrument
          believed by it in good faith to be valid and to have been signed or
          presented by the proper party or parties, (ii) be responsible for any
          failure on the part of the Company to comply with any of its covenants
          and obligations contained in this instrument or in the Warrant
          certificates, or (iii) be liable for any act or omission in connection
          with this Agreement except for its own negligence or willful
          misconduct.

     (c)  The Warrant Agent may at any time seek legal advice of counsel (who
          may be counsel to the Company) and shall incur no liability or
          responsibility for any action taken or omitted by it in good faith in
          accordance with such notice, statement, instrument, request,
          direction, order or demand.

     (d)  Any notice, statement, instruction, request, direction, order or
          demand of the Company shall be sufficiently evidenced by an instrument
          signed by any officer of the Company. The Warrant Agent shall not be
          liable for any action taken or omitted by it in accordance with such
          notice, statement, instruction, request, direction, order or demand.

     (e)  The Company agrees to pay the Warrant Agent reasonable compensation
          for its services hereunder and to reimburse the Warrant Agent for its
          reasonable expenses. The Company further agrees to indemnify the
          Warrant Agent against any and all losses, expenses and liabilities,
          including judgments, costs and fees, for any action taken or omitted
          by the Warrant Agent in the execution of its duties and powers,
          excepting losses, expenses and liabilities arising as a result of the
          Warrant Agent's negligence or willful misconduct.

8.   General

     (a)  The Company will concurrently with the issue of the same to holders of
          Common Stock send to each holder of a Warrant (or, in the case of
          joint holders, to the first named) a copy of each published annual
          report and accounts of the Company and unaudited interim report of the

                                       5
<PAGE>

          Company together with all documents required by law to be annexed
          thereto, and copies of every statement, notice or report issued to
          holders of Common Stock.

     (b)  For the purposes of this Warrant Instrument, "business day" means a
          day (excluding Saturdays and public holidays) on which banks in the
          States of Oklahoma and Texas are open for business. All the provisions
          of the Bylaws of the Company as to meetings of the shareholders shall
          apply mutatis mutandis as though each series of the Warrants formed a
          separate class of Common Stock of the Company but so that (i) the
          period of notice shall be 21 days at least, (ii) the necessary quorum
          shall be Warrant Holders of the relevant series (present in person or
          by proxy) entitled to subscribe for one-third of the Common Stock
          attributable to the then outstanding Warrants of that series, (iii)
          every Warrant Holder present in person at any such meeting shall be
          entitled to one vote for every such share of Common Stock for which he
          is entitled to subscribe, and (iv) if at any adjourned meeting a
          quorum as defined above is not present, a Warrant Holder who is then
          present in person or by proxy shall be a quorum.

     (c)  The invalidity of any undertaking, or any part of any undertaking, in
          paragraph 3 shall not affect the validity of any other part of that
          paragraph. If any event occurs which, but for any rule of law, would
          be a breach of paragraph 3, the Company shall pay to the Warrant
          Holders such sum as the auditors of the Company shall determine to be
          equal to the loss in value of the Warrants resulting from such event.

     (d)  Any determination or adjustment made pursuant to these terms and
          conditions by the auditors of the Company shall be made by them as
          experts and not arbitrators and shall be final and binding on the
          Company and all Warrant Holders.

9.   Governing Law

     THIS AGREEMENT AND THE LEGAL RELATIONS AMONG THE PARTIES HERETO SHALL BE
     GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE
     OF OKLAHOMA, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.

                       ________________________________

                               WARRANT AGREEMENT

                          relating to the issuance of
                             Series I Warrants of
                          American Rivers Oil Company
                        _______________________________
<PAGE>

     THIS WARRANT AGREEMENT (the "Agreement") is entered into as of October 13,
1999 among American Rivers Oil Company, a Delaware corporation ("the Company"),
Alliance Resources Plc, a public limited company formed under the laws of
England and Wales ("Alliance"), and those persons identified on the signature
page of this Agreement as Warrant Holders (the "Warrant Holders").

                                   Recitals

     The Warrant Holders hold convertible loan notes (the "Loan Notes ") of
Alliance pursuant to Loan Note Instruments of Alliance dated May 1, 1997 and
November 5, 1997.

     Alliance and the Company have entered into an Exchange and Merger Agreement
(the "Exchange and Merger Agreement") dated July 22, 1999, providing among other
things for the Company to offer (the "Offer") to acquire all of the outstanding
ordinary shares of Alliance.

     One of the conditions to the completion of the Exchange and Merger
Agreement is that the Company shall enter into agreements with the holders of
the Loan Notes, on terms satisfactory to Alliance, providing that after the
Offer becomes unconditional each then outstanding Loan Note shall be exchanged
for the right to receive warrants of the Company having terms substantially
similar to the terms of the Loan Notes.

     The parties to this Agreement desire to provide for the exchange of the
Loan Notes for warrants of the Company.

     Now, therefore, in consideration of the premises and the mutual agreements
of the parties, the parties to this Agreement hereby agree as follows:

                                   Agreement
I.   INTERPRETATION

     In this Warrant Agreement, unless the context otherwise requires, the
     expressions defined in the particulars of Warrants set out in the Schedule
     hereto shall have the meanings thereby given.

II.  WARRANTS

     A.   The Warrants shall be constituted as 1,193,581 Series "I" Warrants
          entitling the holders to subscribe for shares of the common stock,
          $0.001 par value per share (the "Common Stock") of the Company at a
          fixed price of $0.01 per share (subject to the provisions of the
          Schedule hereto) at any time prior to 5:00 p.m. (Tulsa, Oklahoma time)
          on April 30, 2007, the final date for exercise of a Warrant being the
          "Expiration Date" and the price payable upon exercise of a Warrant
          being the "Subscription Price".

     B.   The Warrants shall be issued as follows:

          (i) Each of the Warrant Holders agrees that immediately upon the Offer
     being declared unconditional as provided in Section 2.3 of the Exchange and
     Merger Agreement, each outstanding Loan Note shall be canceled and
     converted solely into the right to receive one Warrant of the Company
     having the terms provided in this Agreement, the Loan Notes shall cease to
     exist, and each holder of a certificate representing any such Loan Notes
     shall thereafter cease to have any rights with respect to such Loan Notes,
     except the right to receive the Warrants of the Company upon the surrender
     of such certificate in accordance with paragraph (iii) below.

                                       2
<PAGE>

          (ii)  On or after the Offer being declared unconditional, each person
     who was immediately before that time a holder of record of Loan Notes may
     deliver to the Company a letter of transmittal duly executed and completed
     in accordance with the instructions thereto, together with such holders'
     certificates representing such Loan Notes and the Company shall deliver to
     such holders certificates in respect of the Warrants of the Company to
     which such holders are then entitled.

     C.   Each of the Warrant Holders represents and agrees as follows:

          (i)   It is the sole legal and beneficial owner of the Loan Notes
     registered in its name, free from any encumbrance arising by, through or
     under such holder, but not otherwise..

          (ii)  It has the requisite power and authority to enter into and
     perform this Agreement and this Agreement and any other documents executed
     by it in connection with this Agreement will, when executed, constitute
     binding obligations of the Warrant Holder enforceable in accordance with
     their respective terms.

          (iii) It is an "accredited investor" as that term is defined in the
     Securities Act of 1933, as amended, and is acquiring the Warrants for its
     own account, and has received all information it believes necessary to
     evaluate its investment in the Warrants.

          (iv)  Each of the Warrant Holders hereby acknowledges and confirms
     that the Warrants and the Common Stock, whether issued or arising as a
     consequence of exercise of the Warrants will be "restricted securities"
     under the United States Securities Act of 1933 (as amended) and that the
     ability to resell such Warrants and such Common Stock will therefore be
     limited.

     D.   Each of Alliance and the Company represents and agrees as follows:

          (i)   The representations and warranties made by each of them in the
     Exchange and Merger Agreement are true and correct.

          (ii)  The execution and performance of this Agreement by each of them
     have been duly and validly authorized by the board of directors of each of
     them, and no other corporate action is necessary to authorize the
     execution, delivery and performance of this Agreement by each of them. Each
     of them has full, absolute and unrestricted right, power and authority to
     execute and perform this Agreement and to carry out the transactions
     contemplated hereby.  This Agreement has been duly and validly executed by
     each of them and this Agreement and any other documents executed by them in
     connection with this Agreement is constitute valid and binding obligations
     of each of them, enforceable in accordance with their respective terms.

          (iii) They will not modify or amend the terms of the Offer or the
     Exchange and Merger Agreement without the consent of the Warrant Holders.

III. CERTIFICATES

     Every Warrant Holder shall be entitled to receive one certificate for each
     Series of the Warrant(s) held by him but joint holders shall be entitled to
     only one certificate in respect of the Warrants held jointly by them which
     certificates shall be delivered to the joint holder whose name stands first
     in the Register.  The Company shall comply with the terms and conditions of
     the Schedule hereto and the Warrants shall be held subject to such terms
     and conditions all of which terms shall be deemed to be

                                       3
<PAGE>

     incorporated in this Warrant Agreement and shall be binding on the Company
     and the Warrant Holders and all persons claiming through or under them
     respectively.

IV.  APPOINTMENT OF WARRANT AGENT

     The Company may in its absolute discretion by resolution of its Board of
     Directors appoint as agent of the Company such person or persons as it
     thinks fit to act in connection with the issue, registration, transfer and
     exchange or otherwise of warrants (the "Warrant Agent").  The Company
     agrees that the Warrant Agent shall perform the duties and obligations
     required of it in accordance with the terms and conditions of the Schedule
     hereto and any other terms that the Company sees fit and to undertake all
     responsibilities hereby vested for the time being in the Company.

V.   MISCELLANEOUS

          parties to this Agreement shall survive after the Offer is declared
          unconditional.

     B.   Except as otherwise provided in this Agreement, the parties shall each
          pay their own expenses and costs in connection with this Agreement and
          the transactions contemplated hereby.

     C.   Subject to the requirements of law and regulatory bodies, no party
          shall make any public announcement or press release with respect to
          this transaction without first consulting with the other parties and
          giving such parties the opportunity to review and comment thereon.

     D.   This Agreement and all of the provisions hereof shall be binding upon
          and inure to the benefit of the parties hereto and their respective
          heirs, personal representatives, successors and assigns.

     E.   Any provision of this Agreement that is prohibited or unenforceable in
          any jurisdiction shall, in such jurisdiction, be ineffective to the
          extent of such prohibition or unenforceability without invalidating
          the remaining provisions hereof, and any such prohibition or
          unenforceability in any jurisdiction shall not invalidate or render
          unenforceable such provision in any other jurisdiction.

     F.   This Agreement (including the instruments between the parties referred
          to herein and any waivers delivered pursuant hereto) constitutes the
          entire agreement among the parties with respect to the subject matter
          hereof and supersedes all other prior agreements and understandings,
          both written and oral, among the parties, or any of them, with respect
          to the subject matter hereof.  The exhibits are a part of this
          Agreement as if fully set forth herein. All references to articles,
          sections, subsections, paragraphs, clauses, exhibits and schedules
          shall be deemed references to such part of this Agreement, unless the
          context shall otherwise require.

     G.   No supplement, modification, or amendment of this Agreement or waiver
          of any provision of this Agreement will be binding unless executed in
          writing by, or on behalf of, all parties to this Agreement.  No waiver
          of any of the provisions of this Agreement will be deemed or will
          constitute a waiver of any other provision of this Agreement
          (regardless of whether similar), nor will any such waiver constitute a
          continuing waiver unless otherwise expressly provided.

          shall constitute but one agreement.

     J.   The parties shall execute, acknowledge and deliver or cause to be

                                   SCHEDULE

1.   Subscription Rights

     (a)  A registered holder (a "holder") of a Warrant shall have the right,
          exercisable in accordance with paragraph 1(c) below, to subscribe (the
          "subscription rights") in cash on any date prior to the Expiration
          Date in respect of such Warrant, on the following terms: for each
          Warrant specified in the Warrant certificate one share of Common Stock
          at the Subscription Price in respect of such Warrant payable in full
          on subscription. The number of shares of Common Stock to be subscribed
          and the subscription price are subject to adjustment pursuant to
          paragraph 2 below. The subscription rights will not be exercisable in
          respect of a fraction of a share of Common Stock. Failure to exercise
          a Warrant prior to 5:00 p.m. (Tulsa, Oklahoma time) on the relative
          Expiration Date will mean that the Warrant shall become void and all
          rights attaching to such Warrant shall cease.

     (b)  The number of Warrants to which each registered holder of Warrants
          shall be entitled shall be evidenced by a Warrant certificate issued
          by the Company. Warrant certificates shall be dated as of the date of
          issue, whether on initial issue, transfer, exchange or in lieu of
          mutilated, lost, stolen or destroyed Warrant certificates. Warrants
          shall be deemed to have been exercised immediately prior to the close
          of business on the date of the surrender for exercise of the Warrant
          certificate.

     (c)  In order to exercise the subscription rights in respect of any
          Warrants, the registered Warrant Holder must, after completing the
          notice of exercise on his Warrant certificate, deliver it to the
          office of the Warrant Agent for the Company accompanied by a
          remittance for the total subscription price of the shares of Common
          Stock in respect of which the subscription rights are being exercised.
          Once delivered, a notice of subscription shall be irrevocable except
          with the consent of the Directors of the Company.

     (d)  Shares of Common Stock issued pursuant to the exercise of subscription
          rights will be issued not later than 14 days after, and with effect
          from, the date on which the related duly completed subscription notice
          shall be delivered to the Warrant Agent for the Company (the
          "subscription date") and Common Stock certificates in respect of such
          shares of Common Stock will be issued free of charge and mailed (at
          the risk of the persons entitled thereto) not later than 14 days after
          the relevant subscription date to the first named person in whose name
          the Warrants are registered at the relevant subscription date or
          (subject as provided by law) to such other persons as may be named in
          the form of nomination upon the reverse of the Warrant certificate. In
          the event that not all of the Warrants evidenced by a Warrant
          certificate are exercised, the Company shall at the same time issue
          for no payment a fresh Warrant certificate in the name of the Warrant
          Holder for any balance of the subscription rights remaining
          exercisable.

     (e)  Shares of Common Stock issued pursuant to the exercise of subscription
          rights will not be deemed outstanding for any dividends or other
          distributions declared, made or paid in respect of any financial year
          of the Company prior to the financial year in which the relevant
          subscription date falls, nor shall they be deemed outstanding for any
          dividends or other distributions declared, made or paid on a date (or
          by reference to a record date) prior to the relevant subscription date
          but, subject thereto, will be treated pari passu in all other respects
          with the shares of Common Stock issued at the relevant subscription
          date including being

                                       1
<PAGE>

          deemed issued for all dividends and other distributions in respect of
          the financial year in which the relevant subscription date occurs
          provided that on any issuance failing to be made pursuant to paragraph
          3(c) or 3(d) below the shares of Common Stock so to be issued shall
          not be deemed outstanding for any dividends or other distributions
          declared, made or paid by reference to a record date prior to the date
          of issuance.

     (f)  To the extent not then exercised, all subscription rights in respect
          of the Warrants shall lapse at 5:00 p.m. (Tulsa, Oklahoma time) on the
          Expiration Date in respect of such Warrants.

     (g)  No sale, offering or transfer of the Warrants or the shares underlying
          the Warrants is permitted unless validly registered under the
          Securities Act of 1933, as amended, or exempt from the registration
          requirements of that Act.

2.   Adjustment of Subscription Price

     (a)  If, on a date (or by reference to a record date) on or before the
          relative Expiration Date in respect of a Warrant, the Company shall
          issue any Common Stock by way of dividend to holders of Common Stock
          of record on a date (or by reference to a record date) before the
          relative Expiration Date or upon any consolidation or sub-division of
          the Common Stock before such Expiration Date, the number of shares of
          Common Stock to be issued on any subsequent exercise of the
          subscription rights in respect of that Warrant will be increased or,
          as the case may be, reduced in due proportion and the subscription
          price per share of Common Stock will be adjusted accordingly. On any
          such dividend, consolidation or sub-division the Company will cause
          the auditors of the Company to verify the correctness of the
          appropriate adjustments and, within 28 days of such adjustments,
          notice will be sent to each Warrant Holder of the adjusted number of
          shares of Common Stock to which the Warrant Holder is entitled to
          subscribe in consequence thereof, fractional entitlements being
          ignored, such notice being accompanied by a new Warrant certificate in
          respect of such adjusted number of shares of Common Stock.

     (b)  If, on a date (or by reference to a record date) on or before the
          relative Expiration Date, the Company makes any offer or invitation
          (whether by rights issue, rights offer or otherwise but not being an
          offer to which paragraph 3(c) below applies or an offer of shares in
          lieu of a cash dividend payment) to the holders of Common Stock in
          their capacity as such, or any offer or invitation (not being an offer
          to which paragraph 3(d) below applies) is made to such holders
          otherwise than by the Company, then the Company shall, as far as it is
          able, cause at the same time the same offer or invitation to be made
          to the then Warrant Holders as if their subscription rights had been
          exercisable and had been exercised on the day immediately preceding
          the date (or record date) of such offer or invitation on the terms
          (subject to any adjustment pursuant to paragraph 2(a) above) on which
          the same could have been exercised on the basis then applicable
          provided that, if the Directors shall so resolve, in the case of any
          offer or invitation made by the Company, the Company shall not be
          required to cause the same offer or invitation to be made to the
          Warrant Holders but the subscription price and/or the number of shares
          of Common Stock to be subscribed on any subsequent exercise of the
          subscription rights shall be adjusted accordingly. The Company will
          cause the auditors of the Company to certify in writing the
          appropriateness of the adjustments and, within 28 days, notice will be
          sent to each Warrant Holder together with a new Warrant certificate in
          respect of the adjusted number of share of Common Stock to which that
          Warrant Holder is entitled to subscribe in consequence thereof,
          fractional entitlements being ignored.

                                       2
<PAGE>

     (c)  No adjustment shall be made to the subscription price of a Series of
          Warrants pursuant to paragraph 2(a) or (b) if such adjustment would
          (taken together with the amount of any adjustment carried forward
          under the provisions of this paragraph 2(c)) be less than 1 percent of
          the relative subscription price then in force and on any adjustment
          the adjusted subscription price will be rounded down to the nearest
          $0.01. Any adjustment not so made and any amount by which the
          subscription price is rounded down will be carried forward and taken
          into account in any subsequent adjustment.

3.   Other Provisions

     So long as any subscription rights remain exercisable:

     (a)  the Company shall reserve for issuance sufficient authorized but
          unissued shares to satisfy in full (without the need for the passing
          of any resolution by shareholders) all subscription rights remaining
          exercisable;

     (b)  the Company shall not (except with the consent of the holders of at
          least three-fourths of the Warrants of each Series) issue any Common
          Stock by way of a dividend nor make any such offer as is referred to
          in paragraph 2(b) above if as a result the Company would on any
          subsequent exercise of the subscription rights be obliged to issue
          Common Stock for less than the par value thereof.

     (c)  if at any time an offer or invitation is made by the Company to the
          holders of Common Stock for the purchase by the Company of any of its
          Common Stock, the Company shall simultaneously give notice thereof to
          the Warrant Holders and each such Warrant Holder shall be entitled at
          any time while such offer or invitation is open for acceptance to
          exercise his subscription rights as if they were then exercisable so
          as to take effect as if he had exercised his rights immediately prior
          to the date (or record date) of such offer or invitation;

     (d)  if at any time an offer is made to all holders of Common Stock (or all
          holders of Common Stock other than the offeror and/or any company
          controlled by the offeror and/or persons acting in concert with the
          offeror) to acquire all or any part of the issued shares of the
          Company and the Company becomes aware that as a result of such offer
          the right to cast a majority of the votes which may ordinarily be cast
          on a vote at a meeting of the shareholders of the Company has or will
          become vested in the offeror and/or such persons or companies as
          aforesaid, the Company shall give notice to the Warrant Holders of
          such vesting within 14 days of its becoming so aware, and each such
          Warrant Holder shall be entitled, at any time within the period of 60
          days immediately following the date of such notice, to exercise his
          subscription rights as if they were exercisable on the last day of the
          said 60 day period on the basis (subject to any adjustment pursuant to
          paragraph 2 above) then applicable. Upon the expiry of such period,
          all Warrants shall lapse. Publication of a tender offer providing for
          the acquisition by any person of all or any part of the issued shares
          of the Company shall be deemed to be the making of an offer for the
          purposes of this paragraph 3(d);

     (e)  if the Company commences liquidation, whether voluntary or compulsory
          (except on terms sanctioned by the consent of the holders of at least
          three-fourths of the Warrants), it shall forthwith give notice thereof
          to all holders of Warrants; thereupon each Warrant shall be
          exercisable and each holder of a Warrant will (if in such winding-up
          there shall be a surplus available for distribution among the holders
          of Common Stock (including for this purpose the

                                       3
<PAGE>

          Common Stock which would be issued on the exercise of all the
          outstanding subscription rights) which, taking into account the
          amounts payable on the exercise of the subscription rights, exceeds in
          respect of each share of Common Stock a sum equal to the subscription
          price) be deemed, as of immediately before the date of such order or
          resolution, to have exercised his subscription rights in full and
          shall accordingly be entitled to receive out of the assets available
          on liquidation pari passu with the holders of the Common Stock such a
          sum as he is entitled as a holder of Common Stock to which he becomes
          entitled by virtue of such subscription after deducting a sum per
          share equal to the subscription price; subject to the foregoing, all
          subscription rights shall lapse on liquidation of the Company; and

     (f)  the Company shall not (except with the consent of the holders of at
          least three-fourths of the Warrants of each Series) issue Common Stock
          by way of a dividend unless at the date of such issuance the Directors
          have authority to grant the additional rights to subscribe to which
          the Warrant Holders will by virtue of paragraph 2(a) above to be
          entitled in consequence of such capitalization.

4.   Modification of Rights and Warrant Instrument

     All or any of the rights attached to the Warrants may from time to time
     (whether or not the Company is being wound up) be altered or abrogated with
     the consent of the holders of at least three-fourths of the Warrants of
     each Series affected by such alteration or abrogation.  Such alteration or
     abrogation approved as aforesaid shall be effected by a majority vote of
     the Board of Directors executed by the Company and expressed to be
     supplemental to this Warrant Instrument. Modifications to this Warrant
     Instrument which are of a formal, minor or technical nature, or made to
     correct a manifest error, or any modifications which the Directors consider
     appropriate may be effected by a majority vote of the Board of Directors
     executed by the Company and expressed to be supplemental to this Warrant
     Instrument and notice of such alteration or abrogation or modification
     shall be given by the Company to the Warrant Holders.

5.   Purchase by the Company

     The Company shall be entitled at any time to purchase Warrants on the open
     market or otherwise. Any Warrants so purchased shall be canceled
     immediately and shall not be available for re-issue.

6.   Transfer

     (a)  The Warrants will be registered and transferable in whole or in part
          by instrument of transfer in any usual or common form or in any other
          form which may be approved by the Board of Directors except that no
          transfer of a right to subscribe for a fraction of a share of Common
          Stock shall be effected. Except insofar as the same would be
          inconsistent with this Warrant Instrument, the provisions of the
          Bylaws of the Company relating to the registration, transfer and
          transmission of shares shall apply mutatis mutandis to the Warrants.

     (b)  Notwithstanding any other provision contained herein, for so long as
          any Regulated Entity (as defined herein) holds any Warrants which,
          upon exercise, would result in such Regulated Entity holding more than
          5% of the outstanding Common Stock, such Regulated Entity may only
          transfer the Warrants under the following circumstances:  (i) in a
          widely distributed public offering; (ii) in a transfer pursuant to
          Rule 144 under the United States of America ("U.S.") Securities Act of
          1933, as amended, or any similar rule then in force; (iii) in a

                                       4
<PAGE>

          transfer where the Common Stock underlying the Warrants being
          transferred represent two percent or less of the outstanding Common
          Stock (not including the transfer from the Regulated Entity); (v) in a
          transfer to the Company; (vi) in a transfer to an affiliate or such
          holder or any other Regulated Entity; or (vii) in any method of
          transfer permitted by the Board of Governors of the Federal Reserve
          System of the U.S.

          Once such Regulated Entity holds Warrants and share of Common Stock
          which, after exercise of the Warrants, would constitute 5.0% or less
          of the outstanding Common Stock, the foregoing restrictions on
          transfer shall cease to apply.

          "Regulated Entity" means (i) any entity that is a "bank holding
          company" (as defined in Section 2(a) of the U.S. Bank Holding Company
          Act of 1956, as amended (the "BHC Act")) or any non-bank subsidiary of
          such an entity or (ii) any entity that, pursuant to Section 8(a) of
          the U.S. International Banking Act of 1978, as amended, is subject to
          the provisions of the BHC Act or any non-bank subsidiary of such an
          entity.

7.   Indemnification of Warrant Agent

     (a)  The Warrant Agent shall act as Agent of the Company. The Warrant Agent
          shall not, by issuing and delivering Warrant certificates or by any
          other act, be deemed to make any representations as to the validity or
          value of the Warrant certificates or the Warrants represented thereby
          or of the Common Stock or other property delivered on exercise of any
          Warrant. The Warrant Agent shall not be under any duty or
          responsibility to any holder of the Warrant certificates to make or
          cause to be made any adjustment of the Subscription Price or to
          determine whether any fact exists which may require any such
          adjustments.

     (b)  The Warrant Agent shall not (i) be liable for any statement or fact
          contained in this instrument or for any action taken or omitted by it
          in reliance on any Warrant certificate or other document or instrument
          believed by it in good faith to be valid and to have been signed or
          presented by the proper party or parties, (ii) be responsible for any
          failure on the part of the Company to comply with any of its covenants
          and obligations contained in this instrument or in the Warrant
          certificates, or (iii) be liable for any act or omission in connection
          with this Agreement except for its own negligence or willful
          misconduct.

     (c)  The Warrant Agent may at any time seek legal advice of counsel (who
          may be counsel to the Company) and shall incur no liability or
          responsibility for any action taken or omitted by it in good faith in
          accordance with such notice, statement, instrument, request,
          direction, order or demand.

     (d)  Any notice, statement, instruction, request, direction, order or
          demand of the Company shall be sufficiently evidenced by an instrument
          signed by any officer of the Company. The Warrant Agent shall not be
          liable for any action taken or omitted by it in accordance with such
          notice, statement, instruction, request, direction, order or demand.

     (e)  The Company agrees to pay the Warrant Agent reasonable compensation
          for its services hereunder and to reimburse the Warrant Agent for its
          reasonable expenses. The Company further agrees to indemnify the
          Warrant Agent against any and all losses, expenses and liabilities,
          including judgments, costs and fees, for any action taken or omitted
          by the Warrant

                                       5
<PAGE>

          Agent in the execution of its duties and powers, excepting losses,
          expenses and liabilities arising as a result of the Warrant Agent's
          negligence or willful misconduct.

8.   General

     (a)  The Company will concurrently with the issue of the same to holders of
          Common Stock send to each holder of a Warrant (or, in the case of
          joint holders, to the first named) a copy of each published annual
          report and accounts of the Company and unaudited interim report of the
          Company together with all documents required by law to be annexed
          thereto, and copies of every statement, notice or report issued to
          holders of Common Stock.

     (b)  For the purposes of this Warrant Instrument, "business day" means a
          day (excluding Saturdays and public holidays) on which banks in the
          States of Oklahoma and Texas are open for business. All the provisions
          of the Bylaws of the Company as to meetings of the shareholders shall
          apply mutatis mutandis as though each series of the Warrants formed a
          separate class of Common Stock of the Company but so that (i) the
          period of notice shall be 21 days at least, (ii) the necessary quorum
          shall be Warrant Holders of the relevant series (present in person or
          by proxy) entitled to subscribe for one-third of the Common Stock
          attributable to the then outstanding Warrants of that series, (iii)
          every Warrant Holder present in person at any such meeting shall be
          entitled to one vote for every such share of Common Stock for which he
          is entitled to subscribe, and (iv) if at any adjourned meeting a
          quorum as defined above is not present, a Warrant Holder who is then
          present in person or by proxy shall be a quorum.

     (c)  The invalidity of any undertaking, or any part of any undertaking, in
          paragraph 3 shall not affect the validity of any other part of that
          paragraph. If any event occurs which, but for any rule of law, would
          be a breach of paragraph 3, the Company shall pay to the Warrant
          Holders such sum as the auditors of the Company shall determine to be
          equal to the loss in value of the Warrants resulting from such event.

     (d)  Any determination or adjustment made pursuant to these terms and
          conditions by the auditors of the Company shall be made by them as
          experts and not arbitrators and shall be final and binding on the
          Company and all Warrant Holders.

9.   Governing Law

     THIS AGREEMENT AND THE LEGAL RELATIONS AMONG THE PARTIES HERETO SHALL BE
     GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE
     OF OKLAHOMA, WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.

12.8 The following provisions will apply in the event of a Change in Control:

     (a)  The Board recognizes that the Executive is one of several key
          employees whose high quality of job performance is essential to
          promoting and protecting the best interests of the Company and its
          shareholders. The Board further recognizes (i) that it is possible
          that a Change in Control of the Company could occur at some time in
          the future, (ii) that the uncertainty associated with such a
          possibility could result in the distraction of the Executive from his
          assigned duties and responsibilities, (iii) that it is in the best
          interest of the Company and its shareholders to assure the continued
          attention by the Executive to such duties and responsibilities without
          such distraction, and (iv) that the Executive must be able to
          participate in the assessment and evaluation of any proposal which
          could effect a Change in Control of the Company without the Executive
          being influenced in the exercise of his judgment by uncertainties
          regarding the Executive's future financial security.

     (b)  A "Change in Control" of the Company shall occur if, after the date of
          this Agreement

          (i)   any Unrelated Party (as hereinafter defined) becomes the
                beneficial owner, directly or indirectly, of thirty percent
                (30%) or more of the common stock of the Company issued and
                outstanding immediately prior to such acquisition and/or
                securities of the Company which may be converted into shares of
                common stock of the Company, computing such percentage as if
                such securities acquired had been converted and are issued and
                outstanding for the purpose of determining such percentage or,
                if any Unrelated Party is the beneficial owner of thirty percent
                (30%) or more of such securities at the date of this Agreement,
                such Unrelated Party acquires an additional ten percent (10%) of
                the shares of common stock of the Company and/or securities of
                the Company which may be converted into shares of common stock
                of the Company;

          (ii)  the shareholders of the Company approve (x) any consolidation or
                merger of the Company in which the Company is not the continuing
                or surviving corporation or pursuant to which shares of the
                common stock of the Company are converted into cash, securities
                or other property, other than a merger of the Company in which
                the holders of the common stock of the Company immediately prior
                to the merger have the same proportionate ownership of common
                stock of the surviving corporation immediately after the merger,
                or (y) any sale, lease, exchange or other transfer (in one
                transaction or a series of related transactions) of all, or
                substantially all, of the assets of the Company, or (z) any plan
                or proposal for the liquidation or dissolution of the Company;

                                       11
<PAGE>

          (iii) a majority of the Board ceases to consist of Continuing
                Directors. "Continuing Directors" shall mean members of the
                Board who either (1) are members of the Board at the date of
                this Agreement or (2) are nominated or appointed to serve as
                directors by a majority of the then Continuing Directors; or

          (iv)  any tender or exchange offer is made to acquire thirty percent
                (30%) or more of the common stock of the Company, other than an
                offer made by the Company, and shares are acquired pursuant to
                that offer.

     (c)  "Unrelated Party" shall mean any party or group of parties acting
          together; excluding, however, the Company, a subsidiary of the Company
          and any trustee under any employee benefit plan maintained by the
          Company.

     (d)  Upon (x) the termination of the Executive by the Company without cause
          following a Change in Control of the Company or (y) the Executive's
          voluntary termination of employment for Good Reason following a Change
          in Control of the Company prior to expiration of the then effective
          two (2) year period of employment, then the Company shall provide to
          the Executive, within thirty (30) days after the applicable event, the
          following benefits:

          (i)   in one lump sum a cash payment equal to 2.5 times (A) the
                Executive's annual salary as specified in this Agreement, and
                (B) aggregate bonuses and benefits for the preceding calendar
                year.

          (ii)  to the extent permitted by applicable law, inclusion in the
                Company's life and medical plans as if the Executive were still
                employed by the Company until the earlier of two (2) years from
                the date of his termination or until the Executive obtains
                eligibility under comparable employee plans, with the Company
                paying that portion of the premium which it was paying for the
                Executive at the time of his termination.

     (e)  Good Reason.  "Good Reason" shall mean:
          ------------

          (i)   Without his express written consent, the assignment to the
                Executive of any duties inconsistent with his positions, duties,
                responsibilities and status with the Company as of the date of
                this Agreement or a change in his titles or offices as of same
                date, or any removal of the Executive from or any failure to re-
                elect the Executive to any of such positions, except in
                connection with the termination of his employment for cause or
                as a result of his

                                       12
<PAGE>

                Disability or death, or termination by the Executive other than
                for Good Reason;

          (ii)  Any reduction of the then-existing base salary or a reduction of

                benefit plans without the prior written consent of the
                Executive, which is not remedied within ten (10) calendar days
                after receipt by the Company of written notice from the
                Executive of such change or reduction, as the case may be;

          (iii) A determination by the Executive made in good faith that as a
                result of a Change in Control of the Company and a change in
                circumstances thereafter significantly affecting his position,
                he has been rendered substantially unable to carry out, or has
                been substantially hindered in the performance of any of the
                authorities, powers, functions, responsibilities or duties
                attached to his position immediately prior to the Change in
                Control of the Company, which situation is not remedied within
                thirty (30) calendar days after receipt by the Company of
                written notice from the Executive of such determination;

          (iv)  Failure by the Company to require any successor (whether direct
                or indirect, by purchase, merger, consolidation or otherwise) to
                all or substantially all of the business and/or assets of the
                Company, by agreement in form and substance satisfactory to the
                Executive, expressly to assume and agree to perform this
                Agreement in the same manner and to the same extent that the
                Company would be required to perform it if no such succession
                had taken place; or

          (v)   The Company shall relocate its principal executive office or
                require Executive to have his principal location of work or
                principal residence any location which is in excess of thirty

       payments or benefit provided by this Agreement nor shall the amounts of
       any payment or benefit provided for by this Agreement be reduced by any
       compensation earned by the Executive as a result of employment by the
       Company or another employer either before or after a Change in Control of
       the Company.

12.10  Nothing in this Agreement shall prevent or limit the Executive's
       continuing or future participation in any benefit, bonus, incentive or
       other plan or program provided by the Company or any of its affiliated
       companies and for which the Executive may qualify, nor shall anything
       herein limit or otherwise affect such

       rights as the Executive may have under any other agreements with the

                 securities of the Company which may be converted into shares of

                 such securities acquired had been converted and are issued and
                 outstanding for the purpose of determining such percentage or,
                 if any Unrelated Party is the beneficial owner of thirty
                 percent (30%) or more of such securities at the date of this
                 Agreement, such Unrelated Party acquires an additional ten
                 percent (10%) of the shares of common stock of the Company

                 shares of common stock of the Company;

           (ii)  the shareholders of the Company approve (x) any consolidation
                 or merger of the Company in which the Company is not the

                 securities or other property, other than a merger of the
                 Company in which the holders of the common stock of the Company
                 immediately prior to the merger have the same proportionate
                 ownership of common stock of the surviving corporation
                 immediately after the merger, or (y) any sale, lease, exchange
                 or other transfer (in one transaction or a series of related

                 the Company, or (z) any plan or proposal for the liquidation or
                 dissolution of the Company;

                 Directors. "Continuing Directors" shall mean members of the

                 directors by a majority of the then Continuing Directors; or

           (iv)  any tender or exchange offer is made to acquire thirty percent
                 (30%) or more of the common stock of the Company, other than an
                 offer made by the Company, and shares are acquired pursuant to
                 that offer.

      (c)  "Unrelated Party" shall mean any party or group of parties acting
           together; excluding, however, the Company, a subsidiary of the
           Company and any trustee under any employee benefit plan maintained by
           the Company.

      (d)  Upon (x) the termination of the Executive by the Company without
           cause following a Change in Control of the Company or (y) the
           Executive's voluntary termination of employment for Good Reason
           following a Change in Control of the Company prior to expiration of
           the then effective two (2) year period of employment, then the
           Company shall provide to the Executive, within thirty (30) days after

                 the date of his termination or until the Executive obtains

                 after receipt by the Company of written notice from the
                 Executive of such change or reduction, as the case may be;

           (iii) A determination by the Executive made in good faith that as a
                 result of a Change in Control of the Company and a change in
                 circumstances thereafter significantly affecting his position,
                 he has been rendered substantially unable to carry out, or has

                 attached to his position immediately prior to the Change in
                 Control of the Company, which situation is not remedied within

                 written notice from the Executive of such determination;

           (iv)  Failure by the Company to require any successor (whether direct
                 or indirect, by purchase, merger, consolidation or otherwise)
                 to all or substantially all of the business and/or assets of

                 Company would be required to perform it if no such succession
                 had taken place; or

           (v)   The Company shall relocate its principal executive office or
                 require Executive to have his principal location of work or
                 principal residence any location which is in excess of thirty

     4.18      ERISA.

     (a)       Set forth on Schedule 4.18 is a list identifying each "employee
benefit plan", as defined in Section 3(3) of ERISA, (i) which is subject to any
provision of ERISA, (ii) which is maintained, administered, or contributed to by
the Company or any affiliate of the Company, and (iii) which covers any employee
or former employee of the Company or any affiliate of the Company or under which
the Company or any affiliate of the Company has any liability. The Company has
delivered or made available to Buyer accurate and complete copies of such plans
(and, if applicable, the related trust agreements) and all amendments thereto
and written interpretations thereof, together with (i) the three most recent
annual reports (Form 5500 including, if applicable, Schedule B thereto) prepared
in connection with any such plan and (ii) the most recent actuarial valuation
report prepared in connection with any such plan. Such plans are referred to in
this Section as the "Employee Plans". For purposes of this Section only, an
"affiliate" of any person means any other person which, together with such
person, would be treated as a single employer under Section 414 of the Code. The
only Employee Plans which individually or collectively would constitute an
"employee pension benefit plan" as defined in Section 3(2) of ERISA are
identified as such on Schedule 4.18.

     (b)       Except as otherwise identified on Schedule 4.18, (i) no Employee
Plan constitutes a "multiemployer plan", as defined in Section 3(37) of ERISA
(for purposes of this Section, a "Multiemployer Plan"), (ii) no Employee Plan is
maintained in connection with any trust described in Section 501(c)(9) of the
Code, (iii) no Employee Plan is subject to Title IV of ERISA or to the minimum
funding standards of ERISA and the Code, and (iv) during the past five years,
neither the Company nor any of its affiliates have made or been required to make
contributions to any Multiemployer Plan. There are no accumulated funding
deficiencies as defined in Section 412 of the Code (whether or not waived) with
respect to any Employee Plan. The fair market value of the assets held with
respect to each Employee Plan which is an employee pension benefit plan, as
defined in Section 3(2) of ERISA, exceeds the actuarially determined present
value of all benefit liabilities accrued under such Employee Plan (whether or
not vested) determined using reasonable actuarial assumptions. Neither the
Company nor any affiliate of the Company has incurred any material liability
under Title IV of ERISA arising in connection with the termination of, or
complete or partial withdrawal from, any plan covered or previously covered by
Title IV of ERISA. The Company and all of the affiliates of the Company have

result in the imposition of a lien against any of the assets of the Company or
any Subsidiary. Nothing done or omitted to be done and no transaction or holding
of any asset under or in connection with any Employee Plan has or will make the
Company or any Subsidiary or any director or officer of the Company or any
Subsidiary subject to any liability under Title I of ERISA or liable for any Tax
pursuant to Section 4975 of the Code that could have a Material Adverse Effect.

or by any participant therein, alleging a breach or breaches of fiduciary duties
or violations of Applicable Laws which could result in liability on the part of
the Company, its officers or directors, or such Employee Plans, under ERISA or
any other Applicable Law and there is no basis for any such claim.

     (c)       Each Employee Plan which is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified since the
date of its adoption, and each trust forming a part thereof is exempt from Tax
pursuant to Section 501(a) of the Code. Set forth on Schedule 4.18 is a list of
the most recent IRS determination letters with respect to any such Plans,
accurate and complete copies of which letters have been delivered or made

but not limited to ERISA and the Code, which are applicable to such Employee
Plans.

appreciation rights, or other forms of incentive compensation or post-retirement
insurance, compensation, or benefits which (i) is not an Employee Plan, (ii) is
entered into, maintained, or contributed to, as the case may be, by the Company
or any affiliate of the Company, and (iii) covers any employee or former
employee of the Company or any affiliate of the Company or under which the
Company or any affiliate of the Company has any liability. Such contracts,
plans, and arrangements as are described in the preceding sentence are referred
to for purposes of this Section as the "Benefit Arrangements". Each Benefit
Arrangement has been maintained in substantial compliance with its terms and
with the requirements prescribed by Applicable Laws.

     (e)       Neither the Company nor any affiliate of the Company has
performed any act or failed to perform any act, and there is no contract,
agreement, plan, or arrangement covering any employee or former employee of the
Company or any affiliate of the Company, that, individually or collectively,
could give rise to the payment of any amount that would not be deductible
pursuant to the terms of Section 162(a)(1) or 280G of the Code, or could give
rise to any penalty or excise Tax pursuant to Section 4980B or 4999 of the Code.

     4.19      Agreements.

     (a)       Set forth on Schedule 4.19 is a list of all the following

     the Company or any Subsidiary to engage in any line of business or compete
     with any other Person in any geographic area or during any period of time,
     other than those that would not have a Material Adverse Effect;

               (xiii) agreements not made in the ordinary course of business;
     and

               (xiv)  other agreements, whether or not made in the ordinary

<PAGE>

     (b)       The Company has delivered or made available to Buyer accurate and
complete copies of the agreements listed in Schedule 4.19.  Each of such
agreements is a valid and binding agreement of the Company and the Subsidiaries
(to the extent each is a party thereto) and (to the best knowledge of the
Company) the other party or parties thereto, enforceable against the Company and
the Subsidiaries (to the extent each is a party thereto) and (to the best
knowledge of the Company) such other party or parties in accordance with its
terms.  Neither the Company nor any Subsidiary is in breach of or in default
under, nor has any event occurred which (with or without the giving of notice or
the passage of time or both) would constitute a default by the Company or any
Subsidiary under, any of such agreements, and neither the Company nor any
Subsidiary has received any notice from, or given any notice to, any other party
indicating that the Company or any Subsidiary is in breach of or in default
under any of such agreements.  To the best knowledge of the Company, no other
party to any of such agreements is in breach of or in default under such
agreements, nor has any assertion been made by the Company or any Subsidiary of
any such breach or default.

     (c)     Neither the Company nor any Subsidiary has received notice of any
plan or intention of any other party to any agreement to exercise any right of
offset with respect to, or any right to cancel or terminate, any agreement, and
neither the Company nor any Subsidiary knows of any fact or circumstance that
would justify the exercise by any such other party of such a right other than
the automatic termination of such agreement in accordance with its terms.
Neither the Company nor any Subsidiary currently contemplates, or has reason to
believe any other Person currently contemplates, any amendment or change to any
agreement, which amendment or change could have a Material Adverse Effect.

     (d)     Without limiting the generality of the other provisions in this
Section 4.19, the Key Employment Agreements are in full force and effect, and
each of John Keenan, Paul Fenemore and Harry Brian Kerr Williams is currently
employed by the Company pursuant to a renewal term under such agreements.

      4.20   Labor Disputes and Acts of God. Neither the business nor the
properties of the Company nor any Subsidiary has been affected by any fire,

applicable foreign and state securities laws or were offered and sold pursuant
to valid exemptions therefrom.

the meaning of the Investment Company Act of 1940, as amended, or an "investment
advisor" within the meaning of the Investment Advisers Act of 1940, as amended.

      4.24   Brokerage Fees.  Neither the Company nor any of its affiliates
has retained any financial advisor, broker, agent or finder or paid or agreed to
pay any financial advisor, broker, agent or finder on account of this Agreement
or any transaction contemplated hereby, which action would subject Buyer or any
of its affiliates to any liability.  The Company shall indemnify and hold
harmless Buyer from and against any and all losses, claims, damages and
liabilities (including legal and other expenses reasonably incurred in
connection with investigating or defending any claims or actions) with respect
to any finder's fee, brokerage commission or similar payment in connection with

      (b)    There are no circumstances which are known, or would on
reasonable inquiry be known, to the Company or any of its Subsidiaries which

administration of the Company or any of its Subsidiaries or to appoint a
receiver of the whole or any part of its undertaking or assets.

      (c)    Neither the Company nor any of its Subsidiaries is deemed unable

Company in this Agreement, and no statement of the Company contained in any
document, certificate or other writing furnished or to be furnished by the
Company or its representatives to Buyer pursuant hereto or in connection
herewith, contains or will contain, at the time of delivery, any untrue
statement of a material fact or omits or will omit, at the time of delivery, to
state any material fact (other than industry-wide risks normally associated with
the type of business conducted by the Company) necessary to make the statements

anticipates would result in a Material Adverse Effect.

     SECTION 2.1.  COMMITMENTS.  On the terms and subject to the conditions of
this Agreement (including Article V), each Lender agrees to make loans ("Loans")
to the Borrowers equal to the aggregate amount of the Borrowing of Loans
requested by the Borrowers to be made pursuant to the Commitments on such day
described in this Section 2.1. On the terms and subject to the conditions
hereof, the Borrowers may from time to time borrow and prepay Tranche A Loans
and Tranche B Loans but may not reborrow any amounts paid or pre-paid in respect
of Tranche C Loans.

Day during the period from and after the Effective Date to the earlier to occur
of (x) Tranche A Availability Termination Date and (y) any Commitment
Termination Date relating to all Commitments or to the Tranche A Commitment,
each Lender will make Tranche A Loans to the Borrowers equal to the amount of
the Tranche A Loan requested by the Borrowers, subject to the limitations in
this Section 2.1, to be made on such day in the applicable Borrowing Request
therefor. The Borrowers acknowledge that, as of October 26, 1998, the aggregate
outstanding principal amount of all Loans (as defined under the Existing

each Lender will

                                      -35-
<PAGE>

make Tranche C Loans to the Borrowers equal to the aggregate amount of the
Tranche C Loan requested by the Borrowers to be made on such day in the
applicable Borrowing Request therefor. The Borrowers acknowledge that, on the
Unified Closing Date, and subject to the satisfaction of each of the conditions
precedent set forth in Section 6.1, the outstanding principal amount of all
Loans (as defined in the Existing Agreement) set forth in Section 2.1.1 plus
accrued and unpaid interest as well as certain fees and expenses, will be
divided into a single Tranche C Loan in the original principal amount of
$5,000,000.00 and a single Tranche A Loan in the original principal amount not
to exceed $18,500,000, and any excess balance of such existing Loans shall
become a Tranche B Loan.

     SECTION 2.1.4.  COMMITMENT TO ISSUE LETTERS OF CREDIT.  From time to time
on any Business Day, the Issuer will issue Letters of Credit, in accordance with
Article IV. The Borrowers acknowledge that, as of October 26, 1998, the Stated

Agreement is $100,000.

     SECTION 2.1.5.  LENDERS NOT REQUIRED TO MAKE LOANS UNDER CERTAIN
CIRCUMSTANCES.  No Lender shall be required to make any Loan if, after giving
effect thereto

          (a)  the aggregate outstanding principal amount of all Tranche A Loans
     would exceed the Tranche A Commitment Amount less the Letter of Credit
     Outstandings, or

          (d)  the aggregate outstanding principal amount of all Loans of such
     Lender, together with its Percentage of all Letter of Credit Outstandings,
     would exceed such Lender's Percentage of the Commitment Amount, or

          (e)  a Borrowing Base Deficiency would exist, or

          (f)  a Collateral Value Deficiency would exist, or

          (g)  an Event of Default has occurred and is continuing.

     SECTION 2.2.1. OPTIONAL. The Borrowers may, from time to time on any
Business Day, voluntarily reduce the Commitments in the following order: first,
the Tranche B Commitment Amount and, when the Tranche B Commitment has been
reduced to zero, then the Tranche C Commitment Amount and, when the Tranche C
Commitment has been reduced to zero, then the Tranche A Commitment Amount;
provided, however, that all such reductions shall require at least three (3)
Business Days' prior notice to the Agent and be permanent, and any partial
reduction of the Commitment Amount shall be in a minimum amount of $250,000 and
in an integral multiple of $50,000.

     SECTION 2.2.2. MANDATORY.

          (a) On the Tranche A Availability Termination Date, the unused portion
     of the Tranche A Commitment Amount shall, without any further action,

     SECTION 2.3. BORROWING PROCEDURE.

                                      -37-
<PAGE>

          (a) By delivering a Borrowing Request to the Agent on or before 10:00
     a.m. (Chicago time) on a Business Day, the Borrowers may from time to time
     irrevocably request, on not less than three (3) nor more than five (5)
     Business Days' notice, or, in the case of a Base Rate Borrowing, one (1)
     Business Day's notice, that a Borrowing be made in a minimum amount of
     $250,000 and an integral multiple of $50,000, or in the unused amount of
     the applicable Commitment.  On the terms and subject to the conditions of
     this Agreement, each Borrowing shall be made on the Business Day specified
     in such Borrowing Request.  The Lenders shall make such funds available to
     the Borrowers by wire transfer to the accounts the Borrowers shall have
     specified in their Borrowing Request.  On or before 11:00 a.m. (Chicago
     time) on such Business Day each Lender shall deposit with the Agent same
     day funds in an amount equal to such Lender's Percentage of the requested
     Borrowing.  Such deposit will be made to an account which the Agent shall
     specify from time to time by notice to the Lenders.  To the extent funds
     are received from the Lenders, the Agent shall make such funds available to
     the Borrowers by wire transfer to the accounts the Borrowers shall have
     specified in their Borrowing Request.  No Lender's obligation to make any
     Loan shall be affected by any other Lender's failure to make any Loan.

          (b) Each Lender may, if it so elects, fulfill its obligation to make,
     continue or convert LIBO Rate Loans hereunder by causing one of its foreign
     branches or  Affiliates (or an international banking facility created by
     such Lender) to make or maintain such LIBO Rate Loan; provided, however,
     that such LIBO Rate Loan shall nonetheless be deemed to have been made and
     to be held by such Lender, and the obligation of the Borrowers to repay
     such LIBO Rate Loan shall nevertheless be to such Lender for the account of
     such foreign branch, Affiliate or international banking facility.  In
     addition, the Borrowers hereby consent and agree that, for purposes of any
     determination to be made for purposes of Section 5.1, 5.2, 5.3 or 5.4, it
     shall be conclusively assumed that each Lender elected to fund all LIBO
     Rate Loans by purchasing Dollar deposits in its LIBO Office's interbank
     eurodollar market.

     SECTION 2.4. CONTINUATION AND CONVERSION ELECTIONS. By delivering a
Continuation/Conversion Notice to the Agent on or before 10:00 a.m. (Chicago
time) on a Business Day, the Borrowers may from time to time irrevocably elect,
on not less than three (3) nor more than five (5) Business Days' notice that
all, or any portion in an aggregate minimum amount of $250,000 and an integral
multiple of $50,000, of any Loans, in the case of Base Rate Loans, be converted
into LIBO Rate Loans or, in the case of LIBO Rate Loans, be converted into a
Base Rate Loan or continued as a LIBO Rate Loan (in the absence of delivery of a
Continuation/Conversion Notice with respect to any LIBO Rate Loan at least three
(3) Business Days before the last day of the then current Interest Period with
respect thereto, such LIBO Rate Loan shall, on such last day, automatically
convert to a Base Rate Loan); provided, however, that

                                      -38-
<PAGE>

no portion of the outstanding principal amount of any LIBO Rate Loan may be
continued as, and no portion of any Base Rate Loan may be converted into, LIBO
Rate Loans when any Default has occurred and is continuing.

     SECTION 2.5. LOAN ACCOUNTS AND NOTES.

          (a) The Loans made by each Lender shall be evidenced by one or more
     loan accounts or records maintained by such Lender in the ordinary course
     of business.  The loan accounts or records maintained by such Lender shall
     be conclusive absent manifest error of the amount of the Loans made by such
     Lender to the Borrowers and the interest and payments thereon.  Any failure
     so to record or any error in doing so shall not, however, limit or
     otherwise affect the obligations of the Borrowers hereunder to pay any
     amount owing with respect to the Loans.

          (b) Each Lender's Loans shall also be evidenced by a Note payable to
     the order of such Lender in a maximum principal amount equal to the
     Lender's Percentage of the original, aggregate Commitment Amount.  The
     Borrowers hereby irrevocably authorize each Lender to make (or cause to be
     made) appropriate notations on the grid attached to the Note (or on any
     continuation of such grid) or in other books and records maintained by such
     Lender, which notations, if made, shall evidence, inter alia, the date of,
     the outstanding principal of, and the interest rate applicable to the Loans
     evidenced thereby (the Borrowers may from time to time reasonably request a
     copy of such grid). Such notations shall be conclusive and binding on the
     Borrowers absent manifest error; provided, however, that the failure of any
     Lender to make any such notations shall not limit or otherwise affect any
     Obligations of the Borrowers or any other Obligor.

          (c) The Borrowers acknowledge that the Notes delivered to the Lenders
     as of the Effective Date amend, restate and renew the promissory notes
     given by the Original Borrowers under the Existing Agreement, which
     amended, restated, consolidated and renewed certain promissory notes and
     other evidence of indebtedness then outstanding.

     SECTION 2.6. BORROWING BASE REDETERMINATION AND COLLATERAL VALUE
REDETERMINATION.

          (a) Within thirty (30) days after receipt of the Engineering Report
     required to be delivered semi-annually, commencing with the interim
     Engineering Report described in Section 2.6(c), (and thereafter in
     connection with the regular, semi-annual Engineering Report), the Agent
     shall notify the Borrowers in writing of the Borrowing Base determined by
     the Agent on the basis of such Engineering Report.  After July 1, 1999, the
     Borrowers or the

                                      -39-
<PAGE>

     Agent may request, and Agent will consider, one (1) additional
     determination of the Borrowing Base at any time during each calendar year,
     including 1999. Each such determination is herein called a "Borrowing Base
     Redetermination". Contemporaneously with each Borrowing Base
     Redetermination that shall occur at any time that any Tranche B Loan is
     outstanding, the Agent shall notify the Borrowers in writing of the
     Collateral Value determined by the Agent on the basis of such Engineering
     Report. Each such determination is herein called a "Collateral Value
     Redetermination". Each Borrowing Base Redetermination (and, as applicable,
     Collateral Value Redetermination) shall be effective as of July 31st (with
     respect to Engineering Reports effective May 1st), January 31st (with
     respect to Engineering Reports effective November 1st) or upon notice from
     the Agent (with respect to any requested Borrowing Base redetermination)
     when the Borrowers are notified of the amount of the redetermined Borrowing
     Base (and, as applicable, the amount of the redetermined Collateral Value)
     by the Agent.

          (b) The Borrowing Base and Collateral Value are also subject to
     adjustment as provided for in Section 3.1.2.

          (c) In addition to the semi-annual Engineering Reports referred to
     above (and in lieu of a November 1 Report for 1998), an interim Reserve and
     Economic Report shall be delivered to Agent by March 31, 1999, and shall
     consist of independent engineering evaluations on all of Borrower's U.S.
     Mortgaged Properties, and the East Irish Sea Assets, if significant changes
     have occurred with respect to the East Irish Sea Assets since the Effective
     Date. Such evaluation shall be prepared by independent consultants which
     are acceptable to the Agent and shall form the basis for the initial
     Borrowing Base Redetermination.  The Agent shall give notice to the
     Borrowers not later than June 1, 1999, of the Borrowing Base and Collateral
     Value determined by the Agent, and such Borrowing Base Redetermination and
     Collateral Value Redetermination shall be effective as of July 1, 1999.

     SECTION 2.7. PURPOSES. The Borrowers shall apply the proceeds of each Loan
only in the following manner:

          (a) in the case of Tranche A Loans, to refinance existing
     indebtedness, for working capital purposes of the Borrowers and to finance
     Approved Development Activities; and

          (b) in the case of Tranche B Loans, as follows:

               1. A portion of the purchase price of the East Irish Sea Assets,
                  in an amount not to exceed $8.0 million;

                                      -40-
<PAGE>

               2. Approved Development Activities in respect of the Mortgaged
                  Properties (other than the East Irish Sea Assets), in an
                  amount not to exceed $2.0 million;

               3. Fees and expenses incurred in connection with the acquisition
                  and financing of the East Irish Sea Assets, in an amount not
                  to exceed in the aggregate $4 million (provided the Borrowers
                  have furnished to the Agent, along with the Borrowing Request
                  applicable thereto, a detailed schedule, satisfactory to the
                  Agent, of such fees and expenses);

               4. Approved Development Activities in respect of the East Irish
                  Sea Assets; and

          (c) in the case of Tranche C Loans, for general corporate and working
     capital purposes.

shall mature and be due and payable, on the Tranche A Availability Termination
Date; provided, however, that if no Event of Default has occurred and is
continuing, the unpaid principal amount of the Tranche A Loans shall, on the
Tranche A Availability Termination Date and in response to a Borrowing Request
delivered to the Lender, not be due and payable but shall convert to term Loans.
The Borrowers shall repay in full the unpaid principal amount of each Loan upon
the applicable Stated Maturity Date. Prior thereto, the Borrowers

          (a) may, from time to time on any Business Day, make a voluntary
     prepayment, in whole or in part, of the outstanding principal amount of any
     Loans; provided, however, that

               (i) any such prepayment shall be made pro rata among Loans of the
          same type and tranche;

                                      -41-
<PAGE>

               (ii)  no such prepayment of any LIBO Rate Loan may be made on any
          day other than the last day of the Interest Period for such Loan;

               (iii) all such voluntary prepayments shall require at least three
          (3) but no more than five (5) Business Days' prior written notice to
          the Agent (which notice is irrevocable) stating the date and amount of
          such prepayment and the type of Loan to be prepaid; and

     prepayment (which shall be applied (or held for application, as the case
     may be) by each Lender to the payment of the aggregate unpaid principal
     amount of those Loans then outstanding and then to the payment of the then
     Letter of Credit Outstandings) equal to the excess, if any, of the
     aggregate outstanding principal amount of all Loans and Letter of Credit
     Outstandings over such Commitment Amount as so reduced;

          (c) shall make prepayments as specified in Section 3.1.2;

          (d) shall, on each Quarterly Payment Date, make a payment in an amount
     not less than the interest payment required pursuant to Section 3.2.3;

     Payment Dates and the applicable Stated Maturity Date;

          (f) shall, if Tranche A Loans have been converted to a term Loan
     pursuant to the terms and conditions hereof, on each Quarterly Payment Date
     after the Tranche A Availability Termination Date, make a payment in an
     amount equal to that necessary to amortize the principal of all Tranche A
     Loans equally over the remaining Quarterly Payment Dates and the applicable
     Stated Maturity Date;

          (g) shall, on the Tranche B Availability Termination Date, pay the
     entire outstanding principal amount of all Tranche B Loans;

          (h) shall, immediately upon any acceleration of the Loans pursuant to
     Section 9.2 or Section 9.3, repay all Loans, unless, pursuant to Section
     9.3, only a portion of all Loans is so accelerated.

                                      -42-

Each payment or prepayment of any Loans made pursuant to this Section shall be
without premium or penalty, except as may be required by Section 5.4, and shall
be applicable, to the extent of such prepayment, in the inverse order of
maturity.  No voluntary prepayment of principal of any Loans or any prepayment
pursuant to the preceding clause (c) shall cause a reduction in any Commitment
Amount.

     SECTION 3.1.2. BORROWING BASE DEFICIENCIES, COLLATERAL VALUE DEFICIENCIES
AND ASSET SALES.

          (a) Upon the occurrence of a Borrowing Base Deficiency and/or a
     Collateral Value Deficiency, the Agent may notify the Borrowers of such
     Borrowing Base Deficiency and/or such Collateral Value Deficiency, as
     applicable.  Within ten (10) Business Days from and after the Borrowing
     Base Deficiency Notification Date and/or such Collateral Value Deficiency
     Notification Date, as applicable, the Borrowers shall notify the Agent and
     the Lenders that they shall take one of the following actions:

               (i)  execute and deliver to the Agent supplemental or additional
          Security Documents, in form and substance reasonably satisfactory to
          the Agent and its counsel, securing payment of the Notes and the other
          Obligations and covering additional Oil and Gas Properties directly
          owned by the Borrowers or one or more of the Borrowers' Subsidiaries
          which are not then covered by any Loan Document and which are of a
          type and nature satisfactory to the Agent, and having a value, in
          addition to other Oil and Gas Properties already subject to a Mortgage
          (determined by the Lender using customary standards for oil and gas
          lending), sufficient to eliminate the Borrowing Base Deficiency and/or
          the Collateral Value Deficiency, as applicable, all as more
          particularly described in Section 8.1.7(a) and (b); or

               (ii) make a payment with respect to the Obligations (which shall
          be applied (or held for application, as the case may be) by the
          Lenders to the payment of the aggregate unpaid principal amount of
          those Loans then outstanding and then to the payment of the then
          Letter of Credit Outstandings) in an aggregate principal amount
          sufficient to eliminate such Borrowing Base Deficiency and/or
          Collateral Value Deficiency, as applicable, within sixty (60) days
          after the Borrowing Base Deficiency Notification Date or Collateral
          Value Deficiency Notification Date, as applicable.

     If the Borrowers shall elect to execute and deliver (or cause one or more
     of the Borrowers' Subsidiaries to execute and deliver) supplemental or
     additional Security Documents to the Agent pursuant to clause (i), they
     shall provide the Agent with descriptions of the additional assets to be
     collaterally assigned

                                      -43-
<PAGE>

     (together with current valuations, Engineering Reports, Security Documents
     described in clause (i) and title evidence applicable thereto, each of
     which shall be in form and substance reasonably satisfactory to the Agent)
     within sixty (60) days after the Borrowing Base Deficiency Notification
     Date or Collateral Value Deficiency Notification Date, as applicable. Such
     supplemental or additional Security Documents shall be subject to the terms
     of Section 8.1.7. If the Borrowers fail to take any of the actions
     described in clauses (i) or (ii) above within such ten (10) Business Day
     period, then without any necessity for notice to the Borrowers or any other
     person, the Borrowers shall become obligated immediately to pay Obligations
     in an aggregate principal amount equal to the applicable Borrowing Base
     Deficiency and/or Collateral Value Deficiency.

          (b) If the Borrowers or any of their Subsidiaries sells, transfers or
     otherwise disposes of Oil and Gas Properties included in the most recent
     determination of the Borrowing Base and the Collateral Value and that have
     a fair market value in the aggregate for the Borrowers and such
     Subsidiaries in excess of $250,000 during the period from the effective
     date of the most recent Borrowing Base Redetermination until the effective
     date of the next Borrowing Base Redetermination, the Borrowing Base and the
     Collateral Value shall be immediately reduced, until the effective date of
     the next Borrowing Base Redetermination and Collateral Value
     Redetermination, by an amount as reasonably determined by the Agent, or if
     the value of the applicable Oil and Gas Properties cannot be readily
     determined by the Agent, by the net sales proceeds realized from the sale,
     transfer or other disposition of such assets.

     If such reduction shall result in a Borrowing Base Deficiency and/or
     Collateral Value Deficiency, then in lieu of the provisions of clause (a)
     of Section 3.1.2, the Borrowers shall immediately make a payment with
     respect to the Obligations in an amount equal to the greater of such
     Borrowing Base Deficiency or such Collateral Value Deficiency.  In addition
     to and cumulative of the foregoing, if a Borrowing Base Deficiency and/or
     Collateral Value Deficiency exists prior to such sale, transfer or other
     disposition of assets, then in lieu of the provisions of clause (a) of
     Section 3.1.2, the Borrower shall, with the written consent of the Agent,
     immediately make a payment with respect to the Obligations (which shall be
     applied (or held for application, as the case may be) by the Lenders first
     to the payment of the aggregate unpaid principal amount of those Loans then
     outstanding, and then to the payment of the then Letter of Credit
     Outstandings) in an aggregate principal amount equal to the lesser of (i)
     the greater of the amount of the Collateral Value Deficiency or the amount
     of the Borrowing Base Deficiency (after giving effect to the applicable
     sale, transfer or other disposition) or (ii) 100% of the net sales proceeds
     realized from the applicable sale, transfer or other disposition.

                                      -44-
<PAGE>

          (c) In addition, if the Borrowers or any of their Subsidiaries raises
     capital through the issuance of any type of equity or issues any
     subordinated debt or senior unsecured debt, the proceeds of such issuance
     will first be applied to cure any Borrowing Base Deficiency and/or
     Collateral Value Deficiency, then as a prepayment of Tranche B Loans and a
     permanent reduction of the Tranche B Commitment, and finally as a
     prepayment of Tranche C Loans and a permanent reduction of the Tranche C
     Commitment.

     SECTION 3.2. INTEREST PROVISIONS. Interest on the outstanding principal
amount of Loans shall accrue and be payable in accordance with this Section 3.2.

     SECTION 3.2.1. RATE. Pursuant to an appropriately delivered Borrowing
Request or Continuation/Conversion Notice, the Borrowers may elect that Loans

     equal to the Alternate Base Rate plus the Applicable Margin from time to
     time in effect; and

          (b) on that portion maintained as a LIBO Rate Loan, during each
     Interest Period applicable thereto, equal to the sum of the LIBO Rate
     (Reserve Adjusted) for such Interest Period plus the Applicable Margin.

All LIBO Rate Loans shall bear interest from and including the first day of the
applicable Interest Period to (but not including) the last day of such Interest
Period at the interest rate determined as applicable to such LIBO Rate Loan.

     SECTION 3.2.2. POST-MATURITY RATES. After (w) the date any principal amount
of any Loan shall have become due and payable (whether on the Stated Maturity
Date, upon acceleration or otherwise), (x) the date any other monetary
Obligation of the Borrowers shall have become due and payable, (y) the date any
other Event of Default shall have occurred (and so long as such Event of Default
shall be continuing), and (z) the date that is sixty (60) days after a Borrowing
Base Deficiency Notification Date or a Collateral Value Deficiency Notification
Date, if the applicable Borrowing Base Deficiency or Collateral Value Deficiency
has not been cured, the Borrowers shall pay, but only to the extent permitted by
Applicable Law, interest (after as well as before judgment) on all Obligations
at a rate per annum equal to

          (a) with respect to LIBO Rate Loans for the period from the date such
     Loan becomes due and payable to the end of the then current Interest
     Period, the higher of (i) the sum of the LIBO Rate (Reserve Adjusted) for
     such Interest Period plus the Applicable Margin plus a margin of 3%, or (ii
     the sum of the Alternate Base Rate plus the Applicable Margin plus a margin
     of 3%; or

                                      -45-

payable, without duplication:

          (a)  on the Stated Maturity Date;

          (b) on the date of any optional or required payment or prepayment, in
     whole or in part, of principal outstanding on such Loan and on that portion
     of such Loan so paid or prepaid;

          (c) with respect to Base Rate Loans, on each Quarterly Payment Date
     occurring after the Effective Date;

          (d) with respect to LIBO Rate Loans, on the last day of each

          (e) on that portion of any Loans which is accelerated pursuant to
     Section 9.2 or Section 9.3, immediately upon such acceleration.

Interest accrued on Loans or other monetary Obligations arising under this
Agreement or any other Loan Document after the date such amount shall have
become due and payable (whether on the Stated Maturity Date, upon acceleration
or otherwise) shall be payable upon demand.

     SECTION 3.2.4. MAXIMUM INTEREST. It is the intention of the parties hereto
to conform strictly to applicable usury laws and, anything herein to the
contrary notwithstanding, the Obligations of the Borrowers to the Lenders under
this Agreement shall be subject to the limitation that payments of interest
shall not be required to the extent that receipt thereof would be contrary to
provisions of Applicable Law applicable to the Lenders limiting rates of
interest which may be charged or collected by the Lenders. Accordingly, if the
transactions contemplated hereby would be usurious under Applicable Law with
respect to the Lenders then, in that event, notwithstanding anything to the
contrary in this Agreement, it is agreed as follows:

          (a) the provisions of this Section 3.2.4 shall govern and control;

          (b) the aggregate of all consideration which constitutes interest
     under Applicable Law that is contracted for, charged or received under this
     Agreement, or under any of the other aforesaid agreements or otherwise in
     connection with this Agreement by the Lenders shall under no circumstances

                                      -46-
<PAGE>

     exceed the maximum amount of interest allowed by Applicable Law (such
     maximum lawful interest rate, if any, with respect to the Lenders herein
     called the "Highest Lawful Rate"), and any excess shall be credited to the
     Borrowers by the Lenders (or, if such consideration shall have been paid in
     full, such excess refunded to the Borrowers);

          (c) all sums paid, or agreed to be paid, to the Lenders for the use,
     forbearance and detention of the indebtedness of the Borrowers to the
     Lenders hereunder shall, to the extent permitted by Applicable Law, be
     amortized, prorated, allocated and spread throughout the full term of such
     indebtedness until payment in full so that the actual rate of interest is
     uniform throughout the full term thereof; and

          (d) if at any time the interest provided pursuant to Sections 3.2.1
     and 3.2.2 together with any other fees payable pursuant to this Agreement
     and deemed interest under Applicable Law, exceeds that amount which would
     have accrued at the Highest Lawful Rate, the amount of interest and any
     such fees to accrue to the Lenders pursuant to this Agreement shall be
     limited, notwithstanding anything to the contrary in this Agreement, to
     that amount which would have accrued at the Highest Lawful Rate, but any
     subsequent reductions, as applicable, shall not reduce the interest to
     accrue to such Lender pursuant to this Agreement below the Highest Lawful
     Rate until the total amount of interest accrued pursuant to this Agreement
     and such fees deemed to be interest equals the amount of interest which
     would have accrued to such Lender if a varying rate per annum equal to the
     interest provided pursuant to Sections 3.2.1 and 3.2.2 had at all times
     been in effect, plus the amount of fees which would have been received but
     for the effect of this Section 3.2.4.

     SECTION 3.3. FEES. The Borrowers agree to pay the fees set forth in this
Section 3.3 and in the Fee Letter. All such fees shall be non-refundable.

     SECTION 3.3.1. UNUSED FEE. The Borrowers shall pay to the Agent for the
account of the Lenders an unused fee, for the period from and including the
Effective Date to, but not including the earlier to occur of (x) the Tranche A
Availability Termination Date, and (y) the Commitment Termination Date, equal to
0.50 of 1% per annum of the average of the actual daily amount during the prior
Fiscal Quarter of (a) $55,000,000 minus (b) the sum of the aggregate outstanding
principal amount of all Loans and all Letter of Credit Outstandings, based on a
year comprised of three hundred sixty (360) days. Accrued unused fees shall be
payable in arrears on each Quarterly Payment Date and on the earlier of the
Commitment Termination Date or the Tranche A Availability Termination Date.

     SECTION 3.3.2. LETTER OF CREDIT STATED AMOUNT FEE. The Borrowers agree to
pay to the Agent, for the account of the Issuer, a fee for each Letter of Credit
for the

                                      -47-
<PAGE>

period from and including the date of the issuance of such Letter of
Credit to (but not including) the date upon which such Letter of Credit expires,
at a rate per annum equal to the Applicable Margin for Tranche A Loans
maintained as LIBO Rate Loans on the Stated Amount of such Letter of Credit,
based on a year comprised of three hundred and sixty (360) days. A prorated
portion of such fee shall be payable by the Borrowers in arrears on each
Quarterly Payment Date, and on the earlier of the Tranche A Availability
Termination Date and the Tranche A Commitment Termination Date for any period
then ending for which such fee shall not theretofore have been paid, commencing
on the first such date after the issuance of such Letter of Credit. After any
Borrowing Base Deficiency and/or Collateral Value Deficiency has or have existed
for sixty (60) consecutive days, the Stated Amount Fee on all Letters of Credit
shall increase by 3.00% until such Borrowing Base Deficiency and/or Collateral
Value Deficiency has or have been eliminated.

     SECTION 3.3.3. LETTER OF CREDIT ISSUANCE FEE. The Borrowers agree to pay to
the Agent, for the account of the Issuer, an issuance fee for each Letter of
Credit issued by the Issuer for the period from and including the date of
issuance of such Letter of Credit to (but not including) the date upon which
such Letter of Credit expires, of the greater of 0.25 of 1% of the Stated Amount
of such Letter of Credit or $300.00. Such fee shall be payable on the date of
issuance of such Letter of Credit.

     SECTION 3.3.4. LETTER OF CREDIT ADMINISTRATIVE FEES. The Borrowers agree to
pay to the Agent, for the account of the Issuer, all reasonable administrative
expenses of the Issuer in connection with the maintenance, modification (if any)
and administration of each Letter of Credit issued by the Issuer upon demand
from time to time pursuant to the Issuer's schedule of charges then in effect.

     SECTION 3.4. PROCEEDS ACCOUNT. The Security Documents contain an assignment
to the Agent by the Borrowers and/or their Subsidiaries, as applicable, of all
production of Hydrocarbons and all proceeds attributable thereto properly
allocable to the Mortgaged Properties. Notwithstanding such assignment of
production, the Borrowers may, until the Agent shall give notice to the
contrary, which notice shall not be unreasonably given, receive such proceeds.
Thereafter, all such proceeds from the sale of such production shall be paid
directly into an account of the Borrowers maintained with the Agent (the
"Proceeds Account"). The Borrowers hereby grant to the Agent, subject to the
prior assignment in favor of the Agent of such production and its proceeds, a
security interest in the Proceeds Account and all proceeds thereof.

     SECTION 3.5. ORRI AND WARRANTS ARE NOT COLLATERAL SECURITY.

          (a) In addition to interest paid on the Loans, Alliance Plc shall
     issue the Warrants and Difco shall grant the Overriding Royalty Interest to
     the

                                      -48-
<PAGE>

     Agent's designee ("Designee"), as additional consideration payable to
     the Agent to be retained in perpetuity and not as additional collateral
     security for the Obligations.

          (b) If all Tranche B Loans are paid in full and the Tranche B
     Commitment is terminated on or before March 26, 2000, then the Borrowers
     may purchase the Overriding Royalty Interest in consideration of the
     payment of a mutually satisfactory purchase price.  Such conveyance shall
     be without recourse, representation or warranty of any kind, except that
     the Designee shall warrant against liens created by, through or under the
     Designee.

          (c) The Overriding Royalty Interest described in the foregoing
     subsections (a) and (b) shall not affect in any way the overriding royalty
     interests previously acquired by the Designee pursuant to the Prior
     Agreement (which was subsequently exchanged for warrants and other
     obligations in respect of Alliance Plc).  Similarly, the Warrants to be
     issued pursuant to this Agreement shall not affect in any way the warrants
     issued to the Designee pursuant to the Prior Agreement.


                                  ARTICLE IV.

                               LETTERS OF CREDIT

     SECTION 4.1. ISSUANCE REQUESTS. By delivering to the Agent an Issuance
Request on or before 12:00 noon (Chicago time), the Borrowers may request, from
time to time prior to the earlier to occur of (x) the Tranche A Availability
Termination Date and (y) any Commitment Termination Date relating to all
Commitments or to the Tranche A Commitment, and on not less than three (3) nor
more than ten (10) Business Days' notice, that the Issuer issue an irrevocable
standby letter of credit in substantially the form of Exhibit K hereto, or in
such other form as may be mutually agreed by the Borrowers and the Issuer (each
a "Letter of Credit"), in support of financial obligations of the Borrowers
incurred in the Borrowers' ordinary course of business and which are described
in such Issuance Request. Upon receipt of an Issuance Request, the Agent shall
promptly notify the Lenders and the Issuer thereof. Each Letter of Credit shall
by its terms:

          (a) be issued in a Stated Amount which

               (i)  is at least $10,000;

               (ii) does not exceed (or would not exceed) the then Letter of
          Credit Availability;

                                      -49-
<PAGE>

          (b) be stated to expire on a date (its "Stated Expiry Date") no later
     than the earlier of (i) one (1) year after its date of issuance and (ii the
     Commitment Termination Date; and

          (c) on or prior to its Stated Expiry Date

               (i)   terminate immediately upon notice to the Issuer from the
          beneficiary thereunder that all obligations covered thereby have been
          terminated, paid, or otherwise satisfied in full,

               (ii)  reduce in part immediately and to the extent the
          beneficiary thereunder has notified the Issuer that the obligations
          covered thereby have been paid or otherwise satisfied in part, or

               (iii) terminate thirty (30) Business Days after notice to the
          beneficiary thereunder from the Agent that an Event of Default has
          occurred and is continuing.

So long as no Default has occurred and is continuing, by delivery to the Agent
and the Issuer of an Issuance Request at least three (3) but not more than ten
(10) Business Days prior to the Stated Expiry Date of any Letter of Credit, the
Borrowers may request the Issuer to extend the Stated Expiry Date of such Letter
of Credit for an additional period not to exceed the earlier of one (1) year
from its date of extension, the Availability Termination Date or the Commitment
Termination Date.

     SECTION 4.2. ISSUANCES AND EXTENSIONS. On the terms and subject to the
conditions of this Agreement (including Article VI), the Issuer shall issue
Letters of Credit, and extend the Stated Expiry Dates of outstanding Letters of
Credit, in accordance with the Issuance Requests made therefor. The Issuer will
make available the original of each Letter of Credit which it issues in
accordance with the Issuance Request therefor to the beneficiary thereof (and
will promptly provide the Agent and each of the Lenders with a copy of such
Letter of Credit) and will notify the beneficiary under any Letter of Credit of
any extension of the Stated Expiry Date thereof.

     The Issuer is under no obligation to issue any Letter of Credit if:

          (i) any order, judgment or decree of any Governmental Agency or
     arbitrator shall by its terms purport to enjoin or restrain the Issuer from
     issuing such Letter of Credit, or any requirement of Applicable Law or any
     request or directive (whether or not having the force of law) from any
     Governmental Agency with jurisdiction over the Issuer shall prohibit, or
     request that the Issuer refrain from, the issuance of letters of credit
     generally or such Letter of Credit in particular or shall impose upon the
     Issuer or the Lenders with respect

                                      -50-
<PAGE>

     to such Letter of Credit any restriction, reserve or capital requirement
     (for which the Issuer is not otherwise compensated hereunder) not in effect
     on the Effective Date, or shall impose upon the Issuer any unreimbursed
     loss, cost or expense which was not applicable on the Effective Date and
     which the Issuer in good faith deems material to it;

          (ii)  one or more of the applicable conditions contained in Article VI
     is not then satisfied;

          (iii) the expiry date of any requested Letter of Credit is prior to
     the maturity date of any financial obligation to be supported by the
     requested Letter of Credit;

          (iv)  any requested Letter of Credit does not provide for drafts, or
     is not otherwise in form and substance acceptable to the Issuer, or the
     issuance of a Letter of Credit shall violate any applicable policies of the
     Issuer;

          (v)   any standby Letter of Credit is for the purpose of supporting
     the issuance of any letter of credit by any other Person; or

          (vi)  such Letter of Credit is in a face amount denominated in a
     currency other than Dollars.

The Uniform Customs and Practice for Documentary Credits as published by the
International Chamber of Commerce most recently at the time of issuance of any
Letter of Credit shall (unless otherwise expressly provided in the Letters of
Credit) apply to the Letters of Credit.

     SECTION 4.3. DISBURSEMENTS. The Issuer will notify the Borrowers promptly
of the presentment for payment of any Letter of Credit, together with notice of
the date (the "Disbursement Date") such payment shall be made. Subject to the
terms and provisions of such Letter of Credit, the Issuer shall make such
payment to the beneficiary (or its designee) of such Letter of Credit. In paying
any drawing under a Letter of Credit, the Issuer shall not have any
responsibility to obtain any document (other than any sight draft and
certificates expressly required by the Letter of Credit) or to ascertain or
inquire as to the validity or accuracy of any such document or the authority of
the Person executing or delivering any such document. Prior to 12:00 noon
(Chicago time) on the Disbursement Date, the Borrowers will reimburse the Issuer
for all amounts which it has disbursed under the Letter of Credit. To the extent
the Issuer is not reimbursed in full in accordance with the preceding sentence,
the Borrowers' Reimbursement Obligation shall accrue interest at a fluctuating
rate equal to the lesser of (i) the Highest Lawful Rate or (ii) the Alternate
Base Rate, plus the Applicable Margin plus a margin of 2% per annum, payable on
demand. In the event the Issuer is not reimbursed by the Borrowers on the
Disbursement Date, or if Issuer

                                      -51-
<PAGE>

must for any reason return or disgorge such reimbursement, BankAmerica shall, on
the terms and subject to the conditions of this Agreement, fund the
Reimbursement Obligation therefor by making, on the next Business Day, Tranche A
Loans which are Base Rate Loans as provided in Section 2.1.2 (the Borrowers
being deemed to have given a timely Borrowing Request therefor for such amount);
provided, however, for the purpose of determining the availability of the
Commitments to make Loans immediately prior to giving effect to the application
of the proceeds of such Loans, such Reimbursement Obligation shall be deemed not
to be outstanding at such time.

     SECTION 4.4. REIMBURSEMENT. The Borrowers' obligation (a "Reimbursement
Obligation") under Section 4.3 to reimburse the Issuer with respect to each
Disbursement (including interest thereon) shall be absolute and unconditional
under any and all circumstances and irrespective of any setoff, counterclaim, or
defense to payment which the Borrowers may have or have had against the Lenders,
the Issuer or any beneficiary of a Letter of Credit, including any defense based
upon the occurrence of any Default, any draft, demand or certificate or other
document presented under a Letter of Credit proving to be forged, fraudulent,
invalid or insufficient, the failure of any Disbursement to conform to the terms
of the applicable Letter of Credit (if, in the Issuer's good faith opinion, such
Disbursement is determined to be appropriate) or any non-application or
misapplication by the beneficiary of the proceeds of such Disbursement, or the
legality, validity, form, regularity, or enforceability of such Letter of
Credit; provided, however, that nothing herein shall adversely affect the right
of the Borrowers to commence any proceeding against the Issuer for any wrongful
Disbursement made by the Issuer under a Letter of Credit as a result of acts or
omissions constituting gross negligence or wilful misconduct on the part of the
Issuer.

     SECTION 4.5. DEEMED DISBURSEMENTS. Upon the occurrence and during the
continuation of any Event of Default or the occurrence of the Commitment
Termination Date, an amount equal to that portion of Letter of Credit
Outstandings attributable to outstanding and undrawn Letters of Credit shall, at
the election of the Issuer, acting on instructions from the Required Lenders,
and without demand upon or notice to the Borrowers, be deemed to have been paid
or disbursed by the Issuer under such Letters of Credit (notwithstanding that
such amount may not in fact have been so paid or disbursed), and, upon
notification by the Issuer to the Agent and to the Borrowers of its obligations
under this Section, the Borrowers shall be immediately obligated to reimburse
the Issuer the amount deemed to have been so paid or disbursed by the Issuer.
Any amounts so received by the Issuer from the Borrowers pursuant to this
Section shall be held as collateral security for the repayment of the Borrowers'
obligations in connection with the Letters of Credit issued by the Issuer. At
any time when such Letters of Credit shall terminate and all Obligations to the
Issuer are either terminated or paid or reimbursed to the Issuer in full, the
Obligations of the Borrowers under this Section shall be reduced accordingly
(subject, however, to reinstatement in the event any payment in respect of such

                                      -52-
<PAGE>

Letters of Credit is recovered in any manner from the Issuer), and the Issuer
will return to the Borrowers the excess, if any, of

          (a) the aggregate amount deposited by the Borrowers with the Issuer
     and not theretofore applied by the Issuer to any Reimbursement Obligation

over

          (b) the aggregate amount of all Reimbursement Obligations to the
     Issuer pursuant to this Section, as so adjusted.

At such time when all Events of Default shall have been cured or waived, the
Issuer shall return to the Borrowers all amounts then on deposit with the Issuer
pursuant to this Section.  All amounts on deposit pursuant to this Section
shall, until their application to any Reimbursement Obligation or their return
to the Borrowers, as the case may be, bear interest at the daily average Federal
Funds Rate from time to time in effect (net of the costs of any reserve
requirements, in respect of amounts on deposit pursuant to this Section,
pursuant to F.R.S. Board Regulation D), which interest shall be held by the
Issuer as additional collateral security for the repayment of the Borrowers'
Obligations in connection with the Letters of Credit issued by the Issuer.

     SECTION 4.6. NATURE OF REIMBURSEMENT OBLIGATIONS. The Borrowers shall
assume all risks of the acts, omissions, or misuse of any Letter of Credit by
the beneficiary thereof. Neither the Lenders nor the Issuer (except to the
extent of its own gross negligence or wilful misconduct) shall be responsible
for:

          (a) the form, validity, sufficiency, accuracy, genuineness, or legal
     effect of any Letter of Credit or any document submitted by any party in
     connection with the application for and issuance of a Letter of Credit,
     even if it should in fact prove to be in any or all respects invalid,
     insufficient, inaccurate, fraudulent, or forged;

          (b) the form, validity, sufficiency, accuracy, genuineness, or legal
     effect of any instrument transferring or assigning or purporting to
     transfer or assign a Letter of Credit or the rights or benefits thereunder
     or proceeds thereof in whole or in part, which may prove to be invalid or
     ineffective for any reason;

          (c) failure of the beneficiary to comply fully with conditions
     required in order to demand payment under a Letter of Credit;

                                      -53-
<PAGE>

          (d) errors, omissions, interruptions, or delays in transmission or
     delivery of any messages, by mail, cable, telegraph, telex, facsimile or
     otherwise; or

          (e) any loss or delay in the transmission or otherwise of any document
     or draft required in order to make a Disbursement under a Letter of Credit
     or of the proceeds thereof;

          (f) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the obligations of the Borrowers in respect of
     any Letter of Credit;

          (g) the existence of any claim, set-off, defense or other right that
     the Borrowers may have at any time against any beneficiary or any
     transferee of any Letter of Credit (or any Person for whom any such
     beneficiary or any such transferee may be acting), the Issuer, the Lenders
     or any other Person, whether in connection with this Agreement, the
     transactions contemplated hereby or by the Letters of Credit or any
     unrelated transaction;

          (h) any payment by the Issuer, or the Lenders under any Letter of
     Credit against presentation of a draft or certificate that does not
     strictly comply with the terms of any Letter of Credit; or any payment made
     by the Issuer, or the Lenders under any Letter of Credit to any Person
     purporting to be a trustee in bankruptcy, debtor-in-possession, assignee
     for the benefit of creditors, liquidator, receiver or other representative
     of or successor to any beneficiary or any transferee of any Letter of
     Credit, including any arising in connection with any insolvency proceeding;
     and

          (i) any other circumstance or happening whatsoever, whether or not
     similar to any of the foregoing, including any other circumstance that
     might otherwise constitute a defense available to, or a discharge of, the
     Borrowers or a guarantor.

None of the foregoing shall affect, impair, or prevent the vesting of any of the
rights or powers granted the Lenders or the Issuer hereunder.  In furtherance
and extension, and not in limitation or derogation, of any of the foregoing, any
action taken or omitted to be taken by the Lenders or the Issuer in good faith
shall be binding upon the Borrowers and shall not put the Lenders or the Issuer
under any resulting liability to the Borrowers.

     SECTION 4.7. INCREASED COSTS; INDEMNITY. If by reason of

          (a) any change in Applicable Law or any change in the interpretation
     or application by any judicial or regulatory authority of any Applicable
     Law, or

                                      -54-
<PAGE>

          (b) compliance by the Agent, the Issuer or any Lender with any
     direction, request or requirement (whether or not having the force of law)
     of any Governmental Agency, including Regulation D of the F.R.S. Board:

               (i)   the Agent, the Issuer or Lender shall be subject to any tax
          (other than taxes on net income and franchises), levy, charge or
          withholding of any nature or to any variation thereof or to any
          penalty with respect to the maintenance or fulfillment of its
          obligations under this Article IV, whether directly or by such being
          imposed on or suffered by the Agent, the Issuer or any Lender;

               (ii)  any reserve, deposit or similar requirement is or shall be
          applicable, increased, imposed or modified in respect of any Letters
          of Credit issued by any Issuer; or

               (iii) there shall be imposed on a Lender any other condition
          regarding this Article IV or any Letter of Credit,

and the result of the foregoing is directly or indirectly to increase the cost
to the Agent, the Issuer or any Lender of issuing or maintaining any Letter of
Credit or to reduce any amount receivable in respect thereof by the Agent, the
Issuer or any Lender, then and in any such case may, at any time after the
additional cost is incurred or the amount received is reduced, notify the
Borrowers thereof, and the Borrowers shall pay on demand such amounts as the
Agent, the Issuer or any Lender may specify to be necessary to compensate the
Agent, the Issuer or any Lender for such additional cost or reduced receipt,
together with interest on such amount from the date demanded until payment in
full thereof at a rate equal at all times to the Alternate Base Rate plus the
Applicable Margin plus 2% per annum.  The determination by the Agent, the Issuer
or any Lender, as the case may be, of any amount due pursuant to this Section,
as set forth in a statement setting forth the calculation thereof in reasonable
detail, shall, in the absence of manifest error, be final and conclusive and
binding on all of the parties hereto.

     In addition to amounts payable as elsewhere provided in this Article IV,
the Borrowers hereby indemnify, exonerate and hold the Agent, the Issuer or any
Lender harmless from and against any and all actions, causes of action, suits,
losses, costs, liabilities and damages, and expenses incurred in connection
therewith (irrespective of whether the Agent, the Issuer or any Lender is a
party to the action for which indemnification is sought), including reasonable
attorneys' fees and disbursements, which the Agent, the Issuer or any Lender may
incur or be subject to as a consequence, direct or indirect, of

                                      -55-
<PAGE>

          (c) the issuance of the Letters of Credit, other than as a result of
     the gross negligence or wilful misconduct of the Issuer as determined by a
     court of competent jurisdiction, or

          (d) the failure of the Issuer to honor a drawing under any Letter of
     Credit as a result of any act or omission, whether rightful or wrongful, of
     any present or future de jure or de facto government or governmental
     authority.

                                  ARTICLE V.

                  CERTAIN INTEREST RATE AND OTHER PROVISIONS

     SECTION 5.1. LIBO RATE LENDING UNLAWFUL. If any Lender shall determine
(which determination shall, upon notice thereof to the Borrowers, be conclusive
and binding on the Borrowers) that the introduction of or any change in or in
the interpretation of any Applicable Law makes it unlawful, or any central bank
or other Governmental Agency asserts that it is unlawful, for such Lender to
make, continue or maintain any Loan as, or to convert any Loan into, a LIBO Rate
Loan, the obligation of the Lender to make, continue, maintain or convert into
any such LIBO Rate Loans shall, upon such determination, forthwith be suspended
until such Lender shall notify the Agent and the Borrowers that the
circumstances causing such suspension no longer exist, and all LIBO Rate Loans
shall automatically convert into Base Rate Loans at the end of the then current
Interest Periods with respect thereto or sooner, if required by such law or
assertion.

     SECTION 5.2. DEPOSITS UNAVAILABLE. If the Agent shall have determined that:

          (a) Dollar deposits in the relevant amount are not available to the
     Agent in its relevant market; or

          (b) by reason of circumstances affecting the Agent's relevant market,
     adequate means do not exist for ascertaining the interest rate applicable
     hereunder to LIBO Rate Loans,

then, upon notice from the Agent to the Borrowers and the Lenders, the
obligations of all Lenders under Section 2.3 to make any Loans shall forthwith
be suspended until the Agent shall notify the Borrowers and the Lenders that the
circumstances causing such suspension no longer exist.

     SECTION 5.3. INCREASED LOAN COSTS, ETC. If by reason of

          (a) any change in Applicable Law or any change in the interpretation
     or application by any judicial or regulatory authority of any Applicable
     Law, or

                                      -56-
<PAGE>

          (b) compliance by any Lender with any direction, request or
     requirement (whether or not having the force of law) of any Governmental
     Agency, including Regulation D of the F.R.S. Board:

               (i)   any Lender shall be subject to any tax (other than taxes on
          net income and franchises), levy, charge or withholding of any nature
          or to any variation thereof or to any penalty with respect to any
          payment due under any LIBO Rate Loan or other amounts due under this
          Agreement, whether directly or by such being imposed on or suffered by
          such Lender;

               (ii)  any reserve, deposit or similar requirement is or shall be
          applicable, increased, imposed or modified in respect of any
          extensions of credit or other assets of, or any deposits with or other
          liabilities of, any Lender or Loans made by such Lender, or against
          any other funds, obligations or other property owned or held by such
          Lender and such Lender actually incurs such additional costs; or

               (iii) there shall be imposed on any Lender any other condition
          affecting this Agreement (or any of such extensions of credit or
          liabilities),

and the result of the foregoing is directly or indirectly to increase the cost
to such Lender of making, continuing or maintaining (or of its obligation to
make, continue or maintain) any Loans as, or of converting (or of its obligation
to convert) any Loans into, LIBO Rate Loans, or to reduce any amount receivable
in respect thereof by such Lender, then and in any such case such Lender may, at
any time after the additional cost is incurred or the amount received is
reduced, notify the Borrowers thereof, and the Borrowers shall pay on demand
such amounts as such Lender may specify to be necessary to compensate such
Lender for such additional cost or reduced receipt, together with interest on
such amount from the date demanded until payment in full thereof at a rate equal
at all times to the Alternate Base Rate plus the Applicable Margin, plus 3% per
annum.  The determination by such Lender of any amount due pursuant to this
Section, as set forth in a statement setting forth the calculation thereof in
reasonable detail, shall, in the absence of manifest error, be final and
conclusive and binding on all of the parties hereto.

     SECTION 5.4. FUNDING LOSSES. In the event any Lender shall incur any loss
or expense (including any loss or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by such Lender to make,
continue or maintain any portion of the principal amount of any Loan as, or to
convert any portion of the principal amount of any Loan into, a LIBO Rate Loan)
as a result of

                                      -57-
<PAGE>

          (a) any conversion or repayment or prepayment of the principal amount
     of any LIBO Rate Loans on a date other than the scheduled last day of the
     Interest Period applicable thereto, whether pursuant to Section 3.1 or
     otherwise;

          (b) any Loans not being made as LIBO Rate Loans in accordance with the
     Borrowing Request therefor by reason of any act or omission by the
     Borrowers or failure of a condition precedent to be satisfied;

          (c) any Loans not being continued as, or converted into, LIBO Rate
     Loans in accordance with the Continuation/ Conversion Notice therefor by
     reason of any act or omission by the Borrowers; or

          (d) any repayment or prepayment of the principal amount of any Loans
     on a date other than the scheduled Monthly Payment Dates;

then, upon the written notice of such Lender to the Borrowers (with a copy to
the Agent), the Borrowers shall, within five (5) days of its receipt thereof,
pay to such Lender such amount as will (in the reasonable determination of such
Lender) reimburse such Lender for such loss or expense.  Such written notice
(which shall include calculations in reasonable detail) shall, in the absence of
manifest error, be conclusive and binding on the Borrowers.

     SECTION 5.5. INCREASED CAPITAL COSTS. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any Applicable Law of any Governmental Agency affects or would
affect the amount of capital required or expected to be maintained by any Lender
or any Person controlling such Lender, and such Lender determines (in its sole
and absolute discretion) that the rate of return on its or such controlling
Person's capital as a consequence of its Commitments, issuance of Letters of
Credit or the Loans made by such Lender is reduced to a level below that which
such Lender or such controlling Person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by such Lender to the Borrowers, the Borrowers shall immediately
pay directly to such Lender additional amounts sufficient to compensate such
Lender or such controlling Person for such reduction in rate of return. A
statement of such Lender as to any such additional amount or amounts (including
calculations thereof in reasonable detail) shall, in the absence of manifest
error, be conclusive and binding on the Borrowers. In determining such amount,
such Lender may use any method of averaging and attribution that it (in its
reasonable discretion) shall deem applicable.

     SECTION 5.6. TAXES. All payments by the Borrowers of principal of, and
interest on, the Loans and all other amounts payable hereunder shall be made
free and clear of and without deduction for any present or future income,
excise, stamp

                                      -58-
<PAGE>

or franchise taxes and other taxes, levies, assessments, imposts, deductions,
fees, duties, withholdings or other charges of any nature whatsoever imposed by
any taxing authority, but excluding franchise taxes and taxes imposed on or
measured by any Lender's net income or receipts (such non-excluded items being
called "Taxes"). In the event that any withholding or deduction from any payment
to be made by the Borrowers hereunder is required in respect of any Taxes
pursuant to any Applicable Law, then the Borrowers will

          (a) pay directly to the relevant authority the full amount required to
     be so withheld or deducted;

          (b) promptly forward to the Agent an official receipt or other
     documentation satisfactory to the Agent evidencing such payment to such
     authority; and

          (c) pay to the Agent for the account of the Lenders such additional
     amount or amounts as is necessary to ensure that the net amount actually
     received by the Lenders will equal the full amount the Lenders would have
     received and retained had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against any Lender with respect to
any payment received by such Lender hereunder, such Lender may pay such Taxes
and the Borrowers will promptly pay such additional amounts (including any
penalties, interest or expenses) as is necessary in order that the net amount
received by such person after the payment of such Taxes (including any Taxes on
such additional amount) shall equal the amount such person would have received
had not such Taxes been asserted.

     If the Borrowers fail to pay any Taxes when due to the appropriate taxing
authority or fail to remit to any Lender the required receipts or other required
documentary evidence, the Borrowers shall indemnify such Lender for any
incremental Taxes, interest or penalties that may become payable by such Lender
as a result of any such failure.

     SECTION 5.7. PAYMENTS, COMPUTATIONS, ETC. Unless otherwise expressly
provided, all payments by the Borrowers pursuant to this Agreement, the Notes or
any other Loan Document shall be made by the Borrowers to the Agent for the pro
rata account of the Lenders entitled to receive such payment. All such payments
shall be made without setoff, deduction or counterclaim, not later than 11:00
a.m. (Chicago time) on the date due, in same day or immediately available funds,
to such account with the Agent in Chicago, Illinois as the Agent shall specify
from time to time by notice to the Borrowers. Funds received after that time
shall be deemed to have been received by the Agent on the next succeeding
Business Day and any applicable interest or fee shall continue to accrue. The
Agent shall promptly remit in

                                      -59-
<PAGE>

same day funds to each Lender its share, if any, of such payments received by
the Agent for the account of such Lender. All interest shall be computed on the
basis of the actual number of days (including the first day but excluding the
last day) occurring during the period for which such interest is payable over a
year comprised of 360 days (or, in the case of interest on a Base Rate Loan
(other than when calculated with respect to the Federal Funds Rate), 365 days
or, if appropriate, 366 days). Whenever any payment to be made shall otherwise
be due on a day which is not a Business Day, such payment shall (except as
otherwise required by clause (c) of the definition of the term "Interest Period"
with respect to LIBO Rate Loans) be made on the next succeeding Business Day and
such extension of time shall be included in computing interest and fees, if any,
in connection with such payment. Notwithstanding any prepayment of a Base Rate
Loan or any conversion of a Base Rate Loan to a LIBO Rate Loan, the Agent will
calculate and invoice the Borrowers for accrued interest thereon through the
date of such prepayment only at the next Quarterly Payment Date.

     SECTION 5.8. SHARING OF PAYMENTS. If any Lender shall obtain any payment or
other recovery (whether voluntary, involuntary, by application of setoff or
otherwise) on account of any Loan (other than pursuant to the terms of Sections
5.3, 5.4 and 5.5) in excess of its pro rata share of payments then or therewith
obtained by all Lenders, such Lender shall purchase from the other Lenders such
participations in Loans made by them and/or Letters of Credit as shall be
necessary to cause such purchasing Lender to share the excess payment or other
recovery ratably with each of them; provided, however, that if all or any
portion of the excess payment or other recovery is thereafter recovered from
such purchasing Lender, the purchase shall be rescinded and each Lender which
has sold a participation to the purchasing Lender shall repay to the purchasing
Lender the purchase price to the ratable extent of such recovery together with
an amount equal to such selling Lender's ratable share (according to the
proportion of

          (a) the amount of such selling Lender's required repayment to the
     purchasing Lender

to

          (b) the total amount so recovered from the purchasing Lender)

of any interest or other amount paid by the purchasing Lender in respect of the
total amount so recovered.  The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section may, to the fullest
extent permitted by law, exercise all its rights of payment (including pursuant
to Section 5.9) with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation.
If under any applicable bankruptcy, insolvency or other similar law, any Lender
receives a secured claim in

                                      -60-
<PAGE>

lieu of a setoff to which this Section applies, such Lender shall, to the extent
practicable, exercise its rights in respect of such secured claim in a manner
consistent with the rights of the Lenders entitled under this Section to share
in the benefits of any recovery on such secured claim.

     SECTION 5.9.  SETOFF. Each Lender shall, upon the occurrence of any Default
described in clauses (a) through (d) of Section 9.1.9 or upon the occurrence of
any other Event of Default, have the right to appropriate and apply to the
payment of the Obligations owing to it (whether or not then due), and (as
security for such Obligations) the Borrowers hereby grant to the Agent and the
Lenders a continuing security interest in, any and all balances, credits,
deposits, accounts or moneys of the Borrowers then or thereafter maintained with
or otherwise held by the Lender, including without limitation, the Proceeds
Account. The Agent and the Lenders agree promptly to notify the Borrowers after
any such setoff and application made by the Lender; provided, however, that the
failure to give such notice shall not affect the validity of such setoff and
application. The rights of the Agent and each Lender under this Section 5.9 are
in addition to other rights and remedies (including other rights of setoff under
Applicable Law or otherwise) which the Agent and the Lenders may have.

     SECTION 5.10. USE OF PROCEEDS. The Borrowers shall apply the proceeds of
each Borrowing in accordance with Section 2.7; without limiting the foregoing,
no proceeds of any Loan will be used to acquire any equity security of a class
which is registered pursuant to Section 12 of the Securities Exchange Act of
1934 or any "margin stock", as defined in F.R.S. Board Regulation U, X or G.

                                  ARTICLE VI.

                                   ARTICLE X

                                   THE AGENT

     SECTION  10.1.  ACTIONS.  Each Lender hereby appoints BankAmerica as its
Agent under and for purposes of this Agreement, the Notes and each other Loan
Document, and BankAmerica hereby accepts such appointment.  Each Lender
authorizes the Agent to act on behalf of such Lender under this Agreement, the
Notes and each other Loan Document and, in the absence of other written
instructions from the Required Lenders received from time to time by the Agent
(with respect to which the Agent agrees that it will comply, except as otherwise
provided in this Section and to the extent such instructions may reasonably be
expected to comply with applicable law), to exercise such powers and to perform
such duties hereunder and thereunder as are specifically delegated to or
required of the Agent by the terms hereof and

                                      -96-
<PAGE>

thereof, together with such powers as may be reasonably incidental thereto;
provided, however, that the Agent shall not take any action that requires the
consent of any Lender unless it receives such consent. Each Lender hereby
indemnifies (which indemnity shall survive any termination of this Agreement)
the Agent, pro rata according to such Lender's Percentage, from and against any
and all liabilities, obligations, losses, damages, claims, costs or expenses of
any kind or nature whatsoever which may at any time be imposed on, incurred by,
or asserted against, the Agent in any way relating to or arising out of this
Agreement, the Notes and any other Loan Document, including reasonable
attorneys' fees, and as to which the Agent is not reimbursed by the Borrowers;
provided, however, that no Lender shall be liable for the payment of any portion
of such liabilities, obligations, losses, damages, claims, costs or expenses
which are determined by a court of competent jurisdiction in a final proceeding
to have resulted solely from the Agent's gross negligence or wilful misconduct.
The Agent shall not be required to take any action hereunder, under the Notes or
under any other Loan Document, or to prosecute or defend any suit in respect of
this Agreement, the Notes or any other Loan Document, unless it is indemnified
hereunder to its satisfaction. If any indemnity in favor of the Agent shall be
or become, in the Agent's determination, inadequate, the Agent may call for
additional indemnification from the Lenders and cease to do the acts indemnified
against hereunder until such additional indemnity is given.

     SECTION  10.2.  FUNDING RELIANCE, ETC.  Unless the Agent shall have been
notified by telephone, confirmed in writing, by any Lender by 5:00 p.m. (Chicago
time) on the day prior to a Borrowing that such Lender will not make available
the amount which would constitute its Percentage of such Borrowing on the date
specified therefor, the Agent may assume that such Lender has made such amount
available to the Agent and, in reliance upon such assumption, make available to
the Borrower a corresponding amount.  If and to the extent that such Lender
shall not have made such amount available to the Agent, such Lender and the
Borrower severally agree to repay the Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
the Agent made such amount available to the Borrowers to the date such amount is
repaid to the Agent, at the interest rate applicable at the time to Loans
comprising such Borrowing.

     SECTION  10.3.  EXCULPATION.  Neither the Agent nor any of its directors,
officers, employees or agents shall be liable to any Lender for any action taken
or omitted to be taken by it under this Agreement or any other Loan Document, or
in connection herewith or therewith, except for its own wilful misconduct or
gross negligence, nor responsible for any recitals or warranties herein or
therein, nor for the effectiveness, enforceability, validity or due execution of
this Agreement or any other Loan Document, nor for the creation, perfection or
priority of any Liens purported to be created by any of the Loan Documents, or
the validity, genuineness, enforceability, existence, value or sufficiency of
any collateral security, nor to make any inquiry respecting the performance by
the Borrowers of their obligations hereunder or under

                                      -97-
<PAGE>

any other Loan Document. Any such inquiry which may be made by the Agent shall
not obligate it to make any further inquiry or to take any action. The Agent
shall be entitled to rely upon advice of counsel concerning legal matters and
upon any notice, consent, certificate, statement or writing which the Agent
believes to be genuine and to have been presented by a proper Person.

     SECTION  10.4.  SUCCESSOR.  The Agent may resign as such at any time upon
at least thirty (30) days' prior notice to the Borrowers and all Lenders, and
the Agent may be removed with or without cause as such by the Required Lenders
upon at least thirty (30) days' prior notice to the Agent and the Borrowers. If
the Agent at any time shall resign or be removed, the Required Lenders may
appoint another Lender as a successor Agent with the consent of the Borrowers
(which consent shall not be unreasonably withheld) which shall Lender thereupon
become the Agent hereunder. If no successor Agent shall have been so appointed
by the Required Lenders, and shall have accepted such appointment, within thirty
(30) days after the giving of notice of resignation or removal, then the
retiring or removed Agent may with the consent of the Borrowers (which consent
shall not be unreasonably withheld), on behalf of the Lenders, appoint a
successor Agent, which shall be one of the Lenders and, if no Lender accepts
such appointment, a commercial banking institution organized under the laws of
the United States (or any State thereof) or a United States branch or agency of
a commercial banking institution, and having a combined capital and surplus of
at least $500,000,000. Upon the acceptance of any appointment as Agent hereunder
by a successor Agent, such successor Agent shall be entitled to receive from the
retiring or removed Agent such documents of transfer and assignment as such
successor Agent may reasonably request, and shall thereupon succeed to and
become vested with all rights, powers, privileges and duties of the retiring or
removed Agent, and the retiring or removed Agent shall be discharged from its
duties and obligations under this Agreement. After any retiring or removed
Agent's resignation or removal hereunder as the Agent, the provisions of

          (a) this Article X shall inure to its benefit as to any actions taken
     or omitted to be taken by it while it was the Agent under this Agreement;
     and

          (b) Section 11.3 and Section 11.4 shall continue to inure to its
     benefit.

     SECTION  10.5.  LOANS OR LETTERS OF CREDIT ISSUED BY BANKAMERICA.
BankAmerica shall have the same rights and powers with respect to (x) the Loans
made by it or any of its Affiliates, (y) the Notes held by it or any of its
Affiliates, and (z) its participating interests in the Letters of Credit as any
other Lender and may exercise the same as if it were not the Agent. BankAmerica
and its Affiliates and each of the Lenders and their respective Affiliates may
accept deposits from, lend money to, and generally engage in any kind of
business with the Borrowers or any Subsidiary or Affiliate of the Borrowers as
if BankAmerica were not the Agent

                                      -98-
<PAGE>

hereunder and in the case of each Lender, as if such Lender were not a Lender
hereunder.

     SECTION  10.6.  CREDIT DECISIONS.  Each Lender acknowledges that it has,
independently of the Agent and each other Lender, and based on such Lender's
review of the financial information of the Borrowers, this Agreement, the other
Loan Documents (the terms and provisions of which being satisfactory to such
Lender) and such other documents, information and investigations as such Lender
has deemed appropriate, made its own credit decision to extend its Commitments.
Each Lender also acknowledges that it will, independently of the Agent and each
other Lender, and based on such other documents, information and investigations
as it shall deem appropriate at any time, continue to make its own credit
decisions as to exercising or not exercising from time to time  any rights and
privileges available to it under this Agreement or any other Loan Document.

     SECTION  10.7.  COPIES, ETC.  The Agent shall give prompt notice to each
Lender of each notice or request required or permitted to be given to the Agent
by the Borrowers pursuant to the terms of this Agreement (unless concurrently
delivered to the Lenders by the Borrowers).  The Agent will distribute promptly
to each Lender each document or instrument received for its account and copies
of all other communications received by the Agent from the Borrowers for
distribution to the Lenders by the Agent in accordance with the terms of this
Agreement.


                                  ARTICLE XI.

                           MISCELLANEOUS PROVISIONS

     SECTION  11.1.  WAIVERS, AMENDMENTS, ETC.

          (a)  The provisions of this Agreement and of each other Loan Document
     may from time to time be amended, modified or waived, if such amendment,
     modification or waiver is in writing and consented to by the Borrowers and
     the Agent; provided, however, that no such amendment, modification or
     waiver which would:

               (i) modify any requirement hereunder that any particular action
          be taken by all the Lenders or by the Required Lenders shall be
          effective unless consented to by each Lender;

               (ii) modify this Section 11.1, change the definitions of
          "Required Lenders" or "Commitment Amount", increase the Percentage of
          any Lender, reduce any fees described in Article III, change the
          amortization schedule  provided for in Section 3.1.1(e), (f) or (g),
          release

          all or substantially all collateral security, except as otherwise
          specifically provided in any Loan Document, or extend the Tranche A
          Availability Termination Date, the Tranche B Availability Termination
          Date, any Stated Maturity Date or the Commitment Termination Date,
          shall be made without the consent of each Lender;

               (iii) extend the due date for, or reduce the amount of, any
          scheduled or mandatory repayment or prepayment of principal of or
          interest on any Loan (or reduce the principal amount of or rate of
          interest on any Loan) shall be made without the consent of each
          Lender;

               (iv)  affect adversely the interests, rights or obligations of an
          Issuer in its capacity as Issuer shall be made without the consent of
          such Issuer; or

               (v)   affect adversely the interests, rights or obligations of
          the Agent in its capacity as the Agent shall be made without consent
          of the Agent.

     No failure or delay on the part of the Agent or the Lenders in exercising
     any power or right under this Agreement or any other Loan Document shall
     operate as a waiver thereof, nor shall any single or partial exercise of
     any such power or right preclude any other or further exercise thereof or
     the exercise of any other power or right.  No notice to or demand on the
     Borrowers in any case shall entitle it to any notice or demand in similar
     or other circumstances.  No waiver or approval by the Agent under this
     Agreement or any other Loan Document shall, except as may be otherwise
     stated in such waiver or approval, be applicable to subsequent
     transactions.  No waiver or approval hereunder shall require any similar or
     dissimilar waiver or approval thereafter to be granted hereunder.

          (b)  This Agreement is an amendment and restatement of, and replaces
     and supersedes the Existing Agreement; provided, however, that no right,
     interest, claim or cause of action of any kind of the Agent or any Lender
     which may have existed under the Existing Agreement shall in any way be
     released, modified, compromised or waived by virtue of this Existing
     Agreement superseding and replacing the Existing Agreement.

     SECTION  11.2.  NOTICES.

          (a) All notices, requests, consents, approvals, waivers and other
     communications shall be in writing (including, unless the context expressly
     otherwise provides, by facsimile transmission, provided that any matter
     transmitted by the Borrowers by facsimile (i) shall be immediately
     confirmed by

                                     -100-
<PAGE>

     a telephone call to the recipient at the number specified on the signature
     pages, and (ii) shall be followed promptly by delivery of a hard copy
     original thereof) and mailed, faxed or delivered, to the address or
     facsimile number specified for notices on the signature pages hereof; or,
     as directed to the Borrowers or the Lenders, to such other address as shall
     be designated by such party in a written notice to the other parties, and
     as directed to any other party, at such other address as shall be

     delivery.

          (c) Any agreement of the Lenders herein to receive certain notices by
     telephone or facsimile is solely for the convenience and at the request of
     the Borrowers.  The Agent and the Lenders shall be entitled to rely on the
     authority of any Person purporting to be a Person authorized by the
     Borrowers to give such notice and the Agent and the Lenders shall not have
     any liability to the Borrowers or other Person on account of any action
     taken or not taken by the Agent and the Lenders in reliance upon such
     telephonic or facsimile notice.  The obligation of the Borrowers to repay
     the Loans shall not be affected in any way or to any extent by any failure
     by a Lender to receive written confirmation of any telephonic or facsimile
     notice or the receipt by the Agent and the Lenders of a confirmation which
     is at variance with the terms understood by the Agent and the Lenders to be
     contained in the telephonic or facsimile notice.

     SECTION  11.3.  PAYMENT OF COSTS AND EXPENSES.  The Borrowers agree to pay
on demand all reasonable expenses of the Agent and each Lender (including the

the Agent) in connection with

          (a) the negotiation, preparation, execution and delivery of this
     Agreement and of each other Loan Document, including schedules and
     exhibits, and any amendments, waivers, consents, supplements or other
     modifications to this Agreement or any other Loan Document as may from time
     to time hereafter be required, whether or not the transactions contemplated
     hereby are consummated,

          (b) the filing, recording, refiling or rerecording of the Mortgages,
     the Security Agreements, the Pledge Agreements and/or any Uniform
     Commercial Code financing statements relating thereto and all amendments,
     supplements,

                                     -101-
<PAGE>

     and modifications to, and all releases and terminations of, any thereof and
     any and all other documents or instruments of further assurance required to
     be filed or recorded or refiled or rerecorded by the terms hereof or of the
     Mortgages, the Security Agreements and the Pledge Agreements, and

          (c) the preparation and review of the form of any document or
     instrument relevant to this Agreement or any other Loan Document.

The Borrowers further agree to pay, and to save the Agent and each Lender
harmless from all liability for, any stamp or other taxes which may be payable
in connection with the execution or delivery of this Agreement, the borrowings
hereunder, the issuance of the Notes, the issuance of the Letters of Credit, or
any other Loan Documents.  The Borrowers also agree to reimburse the Agent and
each Lender upon demand for all reasonable out-of-pocket expenses (including
attorneys' fees and legal expenses of internal and external attorneys) incurred
by the Agent and each Lender in connection with (x) the negotiation of any
restructuring or "work-out", whether or not consummated, of any Obligations and
(y) the enforcement of any Obligations.

     SECTION  11.4.  INDEMNIFICATION.  In consideration of the execution and
delivery of this Agreement by the Agent and each Lender and the extension of the
Commitments, the Borrowers hereby indemnify, exonerate and hold the Agent and
each Lender and each of its officers, directors, employees and agents
(collectively, the "Indemnified Parties") free and harmless from and against any
and all actions, causes of action, suits, losses, costs, liabilities and
damages, and expenses incurred in connection therewith (irrespective of whether
any such Indemnified Party is a party to the action for which indemnification
hereunder is sought), including reasonable attorneys' fees and disbursements
(collectively, the "Indemnified Liabilities"), incurred by the Indemnified
Parties or any of them as a result of, or arising out of, or relating to

          (a) This Agreement, any Loan Document or any document contemplated
     hereby or referred to herein;

          (b) any transaction financed or to be financed in whole or in part,
     directly or indirectly, with the proceeds of any Loan, including the
     transactions contemplated by the Difco Agreement and the Burlington

                                     -102-
<PAGE>

          (d) any investigation, litigation or proceeding related to any
     environmental cleanup, audit, compliance or other matter relating to any
     Environmental Law or the condition of any facility or Property owned,
     leased or operated by any Borrower or any of their Subsidiaries;

          (e) the presence on or under, or the escape, seepage, leakage,
     spillage, discharge, emission, discharging or releases from, any facility
     or Property owned, leased or operated by any Borrower or any of their
     Subsidiaries thereof of any Hazardous Material (including any losses,
     liabilities, damages, injuries, costs, expenses or claims asserted or
     arising under any Environmental Law), regardless of whether caused by, or
     within the control of, such Borrower or any of their Subsidiaries; or

          (f) any misrepresentation, inaccuracy or breach in or of Section 7.17
     or Section 8.1.6,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's gross
negligence or wilful misconduct.  If and to the extent that the foregoing
undertaking may be unenforceable for any reason, the Borrowers hereby agree to
make the maximum contribution to the payment and satisfaction of each of the
Indemnified Liabilities which is permissible under Applicable Law.  The
obligations in this Section 11.4 shall survive payment of all other Obligations.
At the election of any Indemnified Party, the Borrowers shall defend such
Indemnified Party using legal counsel satisfactory to such Indemnified Party in
such Person's sole discretion, at the sole cost and expense of the Borrowers.
All amounts owing under this Section 11.4 shall be paid within thirty (30) days
after demand.

     SECTION  11.5.  SURVIVAL.  The obligations of the Borrowers under Sections
5.3, 5.4, 5.5, 5.6, 11.3 and 11.4 shall in each case survive any termination of

all Commitments.  The representations and warranties made by each Obligor in
this Agreement and in each other Loan Document shall survive the execution and
delivery of this Agreement and each such other Loan Document.

     SECTION  11.6.  SEVERABILITY.  Any provision of this Agreement or any other
Loan Document which is prohibited or unenforceable in any jurisdiction shall, as
to such provision and such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions of
this Agreement or such Loan Document or affecting the validity or enforceability
of such provision in any other jurisdiction.

     SECTION  11.7.  HEADINGS.  The various headings of this Agreement and of
each other Loan Document are inserted for convenience only and shall not affect

                                     -103-
<PAGE>

the meaning or interpretation of this Agreement or such other Loan Document or
any provisions hereof or thereof.

     SECTION  11.8.  EXECUTION IN COUNTERPARTS, EFFECTIVENESS, ETC.  This
Agreement may be executed by the parties hereto in several counterparts, each of
which shall be executed by the Agent, the Borrowers and the Lenders and be
deemed to be an original and all of which shall constitute together but one and
the same agreement. This Agreement shall become effective when counterparts
hereof are executed on behalf of the Agent, the Borrowers and the Lenders.  This
Agreement is made and entered into for the sole protection and legal benefit of
the Agent, the Borrowers and the Lenders and Persons indemnified hereunder, and
their permitted successors and assigns, and no other Person shall be a direct or
indirect legal beneficiary of, or have any direct or indirect cause of action or
claim in connection with, this Agreement or any of the other Loan Documents.

     SECTION  11.9.  GOVERNING LAW; ENTIRE AGREEMENT.  THIS AGREEMENT, THE NOTE
AND EACH OTHER LOAN DOCUMENT (OTHER THAN THE MORTGAGES OR AS EXPRESSLY PROVIDED
IN ANY SUCH DOCUMENT) SHALL EACH BE DEEMED TO BE A CONTRACT MADE UNDER AND
GOVERNED BY THE INTERNAL LAWS OF THE STATE OF ILLINOIS.  This Agreement, the
Note and the other Loan Documents constitute the entire understanding among the
parties hereto with respect to the subject matter hereof and supersede any prior
agreements, written or oral, with respect thereto.

     SECTION  11.10.  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that:

          (a) the Borrowers may not assign or transfer their rights or
     obligations hereunder without the prior written consent of the Agent and
     all Lenders; and

          (b) the rights of sale, assignment and transfer of the Lenders are
     subject to Section 11.11.

     SECTION  11.11.  SALE AND TRANSFER OF LOANS AND NOTE; PARTICIPATIONS IN
LOANS AND NOTE.  Each Lender may assign, or sell participations in, its Loans
and Commitments to one or more other Persons in accordance with this Section
11.11.

     SECTION  11.11.1.  ASSIGNMENTS.  A Lender may at any time assign and
delegate to one or more Persons, including without limitation, banks or other
financial institutions (each Person to whom such assignment and delegation is to
be made, being hereinafter referred to as an "Assignee Lender"), all or any
fraction of such Lender's total Loans and Commitments (which assignment and
delegation shall be of a constant, and not a varying, percentage of all such
Lender's Loans and Commitments) in a minimum aggregate amount of $1,000,000 (or
the entire remaining amount of such Lender's Loans and

                                     -104-
<PAGE>

Commitments); provided, however, that such Lender is required at all times to
maintain Loans, Letter of Credit Outstandings and Commitments hereunder in an
aggregate amount of $1,000,000 (unless such Lender shall have reduced its Loans,
Letter of Credit Outstandings and Commitments to zero); provided, further,
however, that the Borrowers and each other Obligor shall be entitled to continue
to deal solely and directly with such Lender in connection with the interests so
assigned and delegated to an Assignee Lender until

          (a) written notice of such assignment and delegation, together with
     payment instructions, addresses and related information with respect to
     such Assignee Lender, shall have been given to the Borrowers by such Lender
     and such Assignee Lender,

          (b) such Assignee Lender shall have executed and delivered to the
     Borrowers the Agent and such Lender a Lender Assignment Notice, accepted by
     such Lender and the Agent, and

          (c) the processing fees described below shall have been paid.

From and after the date that the Assignee Lender delivers such Lender Assignment
Notice, (x) the Assignee Lender thereunder shall be deemed automatically to have
become a party hereto and to the extent that rights and obligations hereunder
have been assigned and delegated to such Assignee Lender in connection with such
Lender Assignment Notice, shall have the rights and obligations of a Lender
hereunder and under the other Loan Documents, and (y) the assignor Lender, to
the extent that rights and obligations hereunder have been assigned and
delegated by it in connection with such Lender Assignment Notice, shall be
released from its obligations hereunder and under the other Loan Documents.
Within five (5) Business Days after its receipt of notice that the Lender has
received an executed Lender Assignment Notice, the Borrowers shall execute and
deliver to the relevant Assignee Lender a new Note evidencing such Assignee
Lender's assigned Loans and Commitments and, if the assignor Lender has retained
Loans and Commitments hereunder, a replacement Note in the principal amount of
the Loans and Commitments retained by the assignor Lender hereunder (each such
Note to be in exchange for, but not in payment of, the corresponding Note then
held by such assignor Lender).  The assignor Lender shall mark the predecessor
Note "exchanged" and deliver it to the Borrowers.  Accrued interest on that part
of the predecessor Note evidenced by the new Notes, and accrued fees, shall be
paid as provided in the Lender Assignment Notice.  Accrued interest on that part
of the predecessor Note evidenced by the replacement Notes shall be paid to the
assignor Lender.  Accrued interest and accrued fees shall be paid at the same
time or times provided in the predecessor Notes and in this Agreement.  Such
assignor Lender or such Assignee Lender must also pay a processing fee to the
Lender upon delivery of any Lender Assignment Notice in the amount of $2,500.
Any

                                     -105-
<PAGE>

attempted assignment and delegation not made in accordance with this Section
11.11.1 shall be null and void.  Nothing contained in this Agreement shall
prohibit any Lender from pledging or assigning any Note to any Federal Reserve
Bank in accordance with Applicable Law.

     SECTION  11.11.2.  PARTICIPATIONS.  A Lender may at any time sell to one or
more Persons, including without limitation, commercial banks or other Persons
(each of such commercial banks and other Persons being herein called a
"Participant") participating interests in any of the Loans, Commitments, or
other interests of such Lender hereunder; provided, however, that

          (a) no participation contemplated in this Section 11.11 shall relieve
     such Lender from its Commitments or its other obligations hereunder or
     under any other Loan Document,

          (b) such Lender shall remain solely responsible for the performance of
     its Commitments and such other obligations,

          (c) the Borrowers and each other Obligor shall continue to deal solely
     and directly with such Lender in connection with such Lender's rights and
     obligations under this Agreement and each of the other Loan Documents, and

          (d) the Borrowers shall not be required to pay any amount under
     Section 4.6 that is greater than the amount which it would have been
     required to pay had no participating interest been sold.

The Borrowers acknowledge and agree that each Participant, for purposes of
Sections 5.3, 5.4, 5.5 and 5.6 (except as provided in Section 11.11.2(d)), 5.8,
11.3 and 11.4, shall be considered a Lender.

     SECTION  11.12.  FORUM SELECTION AND CONSENT TO JURISDICTION.  ANY
LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE LENDERS, THE
AGENT OR THE BORROWERS SHALL BE BROUGHT AND MAINTAINED IN THE COURTS OF THE
STATE OF ILLINOIS OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN
DISTRICT OF ILLINOIS; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT
AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE AGENT'S OPTION,
IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE
FOUND. THE BORROWERS HEREBY EXPRESSLY AND IRREVOCABLY SUBMIT TO THE JURISDICTION
OF THE COURTS OF THE STATE OF ILLINOIS AND OF THE UNITED STATES DISTRICT COURT
FOR THE NORTHERN DISTRICT OF ILLINOIS FOR THE PURPOSE OF ANY SUCH LITIGATION AS
SET

                                     -106-
<PAGE>

FORTH ABOVE AND IRREVOCABLY AGREE TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY
IN CONNECTION WITH SUCH LITIGATION.  THE BORROWERS FURTHER IRREVOCABLY CONSENT
TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL
SERVICE WITHIN OR WITHOUT THE STATE OF ILLINOIS.  THE BORROWERS HEREBY EXPRESSLY
AND IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION
WHICH THEY MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH
LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY
SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.  TO THE EXTENT THAT
THE BORROWERS HAVE OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF
ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE,
ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH
RESPECT TO ITSELF OR ITS PROPERTY, THE BORROWERS HEREBY IRREVOCABLY WAIVE SUCH
IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS.

     SECTION  11.13.  WAIVER OF JURY TRIAL.  THE AGENT, THE LENDERS AND THE
BORROWERS HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY
MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL
OR WRITTEN) OR ACTIONS OF THE LENDERS, THE AGENT OR THE BORROWERS.  THE
BORROWERS ACKNOWLEDGE AND AGREE THAT THEY HAVE RECEIVED FULL AND SUFFICIENT
CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN
DOCUMENT TO WHICH THEY ARE A PARTY) AND THAT THIS PROVISION IS A MATERIAL
INDUCEMENT FOR THE LENDERS ENTERING INTO THIS AGREEMENT AND EACH SUCH OTHER LOAN
DOCUMENT.

     SECTION  11.14.  JOINT AND SEVERAL LIABILITY.  Each Borrower has determined
that it is in its best interest and in pursuit of its legitimate business
purposes to induce the Lenders to extend credit to the Borrowers pursuant to
this Agreement.  Each Borrower acknowledges and represents that its business is
integrally related to the business of the other Borrowers, that the availability
of the Commitments to all of the Borrowers benefits each Borrower individually
and that the Loans made will be for and inure to the benefit of all of the
Borrowers individually and as a group.  Accordingly, each Borrower shall be
jointly and severally liable (as a principal and not as a surety, guarantor or
other accommodation party) for each and every representation, warranty, covenant
and obligation to be performed by the Borrowers under this Agreement, the Notes
and the other Loan Documents, and each Borrower acknowledges that in extending
the credit provided herein the Lenders are relying upon the fact that the
obligations of each Borrower hereunder are the joint and several obligations of
a principal.  The invalidity, unenforceability or illegality of this

                                     -107-
<PAGE>

Agreement, the Note or any other Loan Document as to one Borrower or the release
by the Agent or any Lender of a Borrower hereunder or thereunder shall not
affect the obligations of the other Borrowers under this Agreement, the Note or
other Loan Documents, all of which shall otherwise remain valid and legally
binding obligations of the other Borrowers.

     SECTION  11.15.  CERTAIN CONSENTS AND WAIVERS.

          (a) The Agent or any Lender may, at any time and from time to time,
     without the consent of or notice to the Borrowers, except such notice as
     may be required by applicable statute which cannot be waived, without
     incurring responsibility to the Borrowers, and without impairing or
     releasing the obligations of the Borrowers in whole or in part, (i)
     exercise or refrain from exercising any rights against any Borrower, (ii)
     sell, exchange, release, surrender, realize upon or otherwise deal with in
     any manner or in any order any property pledged or mortgaged to secure or
     in any manner securing the Obligations, (iii) take and hold any additional
     security for any or all of the Obligations, (iv) apply any sums by
     whomsoever paid or howsoever realized to any Obligations of the Borrowers
     to the Lenders regardless of what Obligations remain unpaid.

          (b) No invalidity, irregularity or unenforceability of the Obligations
     of a Borrower under this Agreement or any other Loan Document shall affect,
     impair or be a defense to the other Borrowers' Obligations.  Each Borrower
     hereby waives, to the extent permitted under Applicable Law, any and all
     benefits and defenses under any statute, regulation, judicial decision or
     other law which purports to exonerate or reduce the liability of a co-
     borrower as a result of any disability or absence of liability of the other
     co-borrower or any defense to liability or enforcement which the other co-
     borrower may have and agrees that, by so doing, such Borrower's obligations
     hereunder shall continue even if the other Borrowers had no liability at
     the time of execution of this Agreement or thereafter ceased or cease to be
     liable.  Each Borrower also waives, to the extent permitted under
     Applicable Law, any and all benefits and defenses under any statute,
     regulation, judicial decision or other law which purports to limit the
     liability of a co-borrower to that of the other co-borrower or to reduce
     the liability of a co-borrower in proportion to any reduction in the
     liability of the other co-borrower and agrees that, by so doing, such
     Borrower's obligations hereunder may be more burdensome than that of the
     other Borrowers.

          (c) Each Borrower, to the extent permitted under Applicable Law,
     hereby waives any right, whether arising under any statute, regulation,
     judicial decision or otherwise, to require the Agent or any Lender to (i)
     proceed against the other Borrowers, (ii) proceed against or exhaust any
     security received from

                                     -108-
<PAGE>

     the other Borrowers, or (iii) pursue any other right or remedy in the
     Agent's or any Lender's power whatsoever.

          (d) Each Borrower further waives, to the extent permitted under
     Applicable Law:  (i) any defense resulting from the absence, impairment or
     loss of any right of reimbursement, subrogation, contribution or other
     right or remedy of such Borrower against the other Borrowers or any
     security, whether resulting from an election by the Agent or any Lender to
     foreclose upon security by judicial or nonjudicial sale or otherwise; (ii)
     any setoff or counterclaim of such Borrower or any defense of any kind
     (including defenses resulting from any disability) or the cessation or stay
     of enforcement from any cause whatsoever of the liability of such Borrower
     (including without limitation the lack of validity or enforceability of
     this Agreement or any other Loan Document); (iii) any right to exoneration,
     in whole or in part, of co-borrowers which would otherwise be applicable;
     (iv) any benefits and defenses under Applicable Law, including without
     limitation any right of subrogation or reimbursement, any right of
     contribution, any right to enforce any remedy which any Lender now has or
     may hereafter have against the other Borrowers, and any benefit of, and any
     right to participate in, any security now or hereafter held or received by
     any Lender; and (v) all valuation, appraisal, extension or redemption laws
     now or hereafter in effect.  Without limiting the generality of the
     preceding clause (iv), each Borrower hereby waives any right to be
     reimbursed by the other Borrowers for any payment of such obligations made
     directly or indirectly by such Borrower or from any property of such
     Borrower, whether arising by way of any statutory, contractual or other
     right of subrogation, contribution, indemnification or otherwise.

          (e) Each Borrower acknowledges that it has the ability, and hereby
     assumes the obligation and responsibility, to keep informed of the
     financial condition of the other Borrowers and of other matters or
     circumstances affecting the ability of the other Borrowers to pay or
     perform their obligations hereunder or the risk of nonpayment and
     nonperformance.  Each Borrower hereby waives, to extent permitted under
     Applicable Law, any obligation on the part of the Lenders to inform such
     Borrower of the financial condition, or any changes in financial condition,
     of the other Borrowers or of any other matter or circumstance which might
     affect the ability of the other Borrowers to pay and perform under this
     Agreement or any other Loan Document, or the risk of nonpayment or
     nonperformance.

     SECTION  11.16.  OTHER TRANSACTIONS.  Nothing contained herein shall
preclude the Agent or any other Lender or any of their respective Affiliates
from engaging in any transaction, in addition to those contemplated by this
Agreement or any other Loan Document, with the Borrower or any of its Affiliates
in which the Borrower or such Affiliate is not restricted hereby from engaging
with any other Person.

LOAN DOCUMENTS REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE

OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
