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 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.

                                    PART I

ITEM 1.  BUSINESS

     AROC Inc. (the Company or AROC) is a Tulsa-based 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.  AROC
(formerly known as American Rivers Oil Company) was incorporated and registered
under the laws of Delaware on July 16, 1999.  AROC's corporate headquarters are
at 4200 East Skelly Drive, Suite 1000, Tulsa, Oklahoma 74135.

     During the fiscal year ended April 30, 2000, AROC acquired all of the
shares of Alliance Resources PLC (Alliance) on the basis of one share of AROC
common stock for each ordinary share of Alliance, with the result that the
former shareholders of Alliance then held approximately 98% of the outstanding
shares of AROC. Therefore, Alliance is deemed to be the predecessor of AROC for
all purposes and 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 acquisition of
Alliance) relate to Alliance.  Furthermore, unless the context otherwise
requires, all references to "AROC" or "the Company" include Alliance Resources
PLC, AROC Inc. and all of their subsidiaries and/or affiliates.

RECENT DEVELOPMENTS

     On May 2, 2000, AROC completed the acquisition of additional oil and gas
properties, a refinancing of its debt and issuance of a new series of preferred
stock.  The transactions involved several different elements.

     Effective May 1, 2000, AROC designated 2,200,000 shares of its authorized
preferred stock as Series A Preferred Stock.  The Series A Preferred Stock
accrues cumulative dividends at the rate of $5.00 per share per year, payable
semiannually.  Until May 1, 2002, dividends are payable in kind through the
issuance of additional shares of preferred stock at a price equal to the fair
market value of the preferred stock at the time of the payment.  The preferred
stock has a liquidation preference of $50.00 per share and may be redeemable at
$50.00 per share at either the Company's or the holder's option upon the
occurrence of certain events.  Each share of preferred stock is convertible at
any time into 384.6 shares of the Company's common stock and has the right to
vote in all matters on the same basis as if the preferred stock had been
converted into common stock.  The terms of the preferred stock prohibit the
Company from taking certain actions without the consent of the holders of the
preferred stock.

     On May 2, 2000, the Company sold to Bank of America, N.A. (Bank of
America), EnCap Equity 1996 Limited Partnership (EnCap 1996 LP), Energy Capital
Investment Company PLC (ECIC), El Paso Capital Investments, L.L.C. (El Paso),
EF-II Holdings, LLC (EF-II), Picosa Creek Limited Partnership (Picosa) and EnCap
Investments, L.L.C. (EnCap Investments) 850,163 shares of the Company's newly
created Series A Preferred Stock for a total consideration of approximately
$42.5 million, received in satisfaction of outstanding obligations to those
parties and in consideration of cash and the purchase of an oil and gas property
interest.

     Also on May 2, 2000, pursuant to four separate Purchase and Sale Agreements
by and between (i) EnCap Equity 1994 Limited Partnership (EnCap 1994 LP), (ii)
ECIC and ECIC Corporation, (iii) EnCap 1996 LP, and (iv) Mountaineer Limited
Partnership, and the Company, the Company also acquired direct or indirect
ownership of oil and gas properties having a net present value, discounted at
10%, of approximately $62 million at May 1, 2000, using non-escalated prices of
$2.50 per mcf of gas and $22.00 per barrel of oil. The properties include
approximately 280 wells located in Texas, Louisiana, New Mexico, and Wyoming.
The properties were acquired in exchange for the issuance to the sellers of an
aggregate of 930,140 shares of the Company's Series A Preferred Stock.

     In addition, on May 2, 2000, the Company entered into a Purchase Agreement
providing for the sale to EnCap 1996 LP, ECIC and El Paso of a total of
$17,000,000 in subordinated notes in exchange for cash in that amount. The
subordinated notes bear interest at the rate of 12% per year, payable
semiannually. Principal is due May 1, 2007. Until May 1, 2002, interest is
payable in kind by increasing the principal amount of the debt. Additionally,
the Company issued to EnCap 1996 LP, ECIC and El Paso warrants to purchase a
total of 39,541,233 shares of the Company's common stock at a price of $0.01 per
share at any time until April 30, 2007 pursuant to such Purchase Agreement.

                                       1
<PAGE>

     As a result of these transactions, the Company has outstanding 55,278,837
shares of common stock, 10,000,000 convertible restricted voting shares,
warrants to purchase 45,813,963 shares of common stock, and 1,780,303 shares of
Series A Preferred Stock that are convertible into an aggregate of 684,731,923
shares of common stock.  EnCap 1996 LP, EnCap 1994 LP, ECIC, EnCap Investments,
Picosa, EF-II and El Paso have the right to vote in the aggregate approximately
80% of the Company's voting securities and Bank of America and its affiliates
have the right to vote approximately 11.6% of the Company's voting securities.

     Pursuant to a Credit Agreement dated as of May 1, 2000, among AROC, Toronto
Dominion (Texas), Inc., individually and as Agent, and the lenders named in that
agreement (the TD Credit Agreement), the Company obtained a new $35,000,000
credit facility. At May 2, 2000, the outstanding principal balance under the TD
Credit Agreement and EnCap subordinated notes was $25,000,000 and $17,000,000,
respectively. The credit facility is secured by a first lien on substantially
all of the Company's assets and the credit facility imposes certain restrictions
on the Company's activities, including the payment of dividends and purchases of
stock. The credit facility provides for a revolving line of credit for three
years. Borrowings under the credit facility bear interest at either the LIBOR
rate plus from 1.75% to 3.0% or the agent's prime rate plus from .25% to 1.5%,
at the Company's election. Interest is payable quarterly beginning July 31,
2000. Principal is payable in full on the third anniversary of the closing of
the credit facility. The borrowing base for the credit facility will typically
be redetermined semiannually, although the lenders and borrowers have the right
to make a redetermination at any time.

     A portion of the proceeds of the cash received from the credit facility and
the sale of the subordinated notes were used to satisfy the Company's
obligations under its previous credit facility with Bank of America and the
remainder will be used for working capital.

COMPETITION

     The oil and natural gas industry is highly competitive in all its phases.
AROC 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. As these
trends toward increasing competition continue, local-market knowledge, operating
efficiency, access to supplies and other factors will affect AROC's success.

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.

EMPLOYEES

     At April 30, 2000, AROC had 20 management and administrative employees and
20 technical and operating employees, none of whom belonged to a union. The
employees include 31 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

     AROC's production is primarily from developed fields close to major
pipelines or refineries and established infrastructure.  As a result, AROC 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

     AROC 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 AROC's gas production is close to existing pipelines and,
consequently, AROC generally has a variety of options to market its gas.  AROC
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

UK (East Irish Sea) Properties

AROC owns non-operated interests in 9 licenses comprising 12 blocks or part-
blocks in the East Irish Sea, offshore UK.  The licenses which are operated by
Burlington Resources (East Irish Sea) Limited, contain 5 proven gas
accumulations, namely the Millom, Dalton, Calder, Crossans and Darwen gas
fields.  Two of these fields, the Millom and Dalton fields, came on-stream on
August 11, 1999.  Currently, 3 wells are producing via sub-sea completions tied
into the North Morecambe Platform.  Gas is currently gathered on the North
Morecambe platform where it is transported via a 20 mile, 36 inch diameter gas
pipeline to onshore processing facilities at Westfield Point, near Barrow-in-
Furness, on the west coast of England.  From Westfield Point the gas is sold
into the UK National Transmission System.  Estimated net remaining reserves for
the 5 proven gas accumulations as of April 30, 2000 were 63,429 MMcf of gas.
AROC has a 10% working interest in these fields.

Gas sales from the producing properties accounted for all of AROC's revenues
from U.K. operations for the year ended April 30, 2000. The following summarizes
AROC's principal areas of oil and gas production activity in the U.K. as of
April 30, 2000.

Dalton Field. The Dalton Field is located approximately 6 miles southwest of the
North Morecambe field central platform in a water depth of 123 ft. In April 2000
the field produced at an average gross rate of 58 MMcfgpd (5.8 MMcfgpd net to
AROC's revenue interest in the property) from 2 wells (Dalton R1 and R2) that
were completed in sandstones of Triassic age at a depth of approximately 3,300
ft. The Dalton R1 well was drilled and completed as a producer in April of 1999
and the Dalton R2 was completed in May 1999 following re-entry of the previously
suspended 110/2b-9 well. The estimated net remaining reserves to AROC's interest
in the field as of April 30, 2000 were 5,518 MMcf of gas.

Millom Field. The Millom Field is located approximately 6 miles north west of
the North Morecambe field central platform in a water depth of 110 ft. In April
2000 the field produced at an average gross rate of 7 MMcfgpd (0.7 MMcfgpd net
to AROC's revenue interest in the property) from 1 well (Millom Q1) which was
completed in sandstones

                                       3

of Triassic age at a depth of around 4,100 ft. The Millom Q1 well was completed
as a producer in June of 1999 following re-entry of the previously suspended
113/27-4/4Z well. A minimum facilities fixed pile platform has since been
installed at West Millom and drilling of the first of 3 wells from this facility
is underway, two of which are to utilize multi-lateral technology. First
production from the West Millom platform is expected in September 2000. The
estimated net remaining reserves to AROC's interest in the field as of April 30,
2000 were 20,321 MMcf of gas.

In addition to these fields, AROC has a working interest in other properties in
the East Irish Sea, including the "Rivers Fields Complex", comprising the
Calder, Crossans and Darwen fields.  AROC is currently evaluating alternatives
for the development of these fields.  Net proved reserves to AROC's interest in
these other properties at April 30, 2000 were 37,590 MMcf of gas.

U.S. Properties

AROC owns and operates producing properties in 12 states in the U.S., with
proved reserves located primarily in the states of Mississippi, Louisiana,
Oklahoma, Texas and Alabama.  AROC 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.

AROC operates 281 producing or potentially productive wells in these areas and
also owns non-operated working interests in 208 producing or potentially
productive wells and non-operated royalty interests in a further 119 wells.  Oil
and gas sales from the producing oil and gas properties accounted for
substantially all of AROC's revenues from U.S. operations for the year ended
April 30, 2000.

The following summarizes AROC's principal areas of oil and gas production
activity in the U.S. as of April 30, 2000.

South Carlton Field, Alabama.  The South Carlton field is located in Clarke and
Baldwin Counties in southwest Alabama. AROC operates 60 active producing or
potentially productive oil wells and 3 salt-water disposal wells.  Production is
from the Massive and Pilot Sands of the Tuscaloosa Formation at depths of 5,250-
6,000 ft.  In April 2000 the field produced at an average gross rate of 427 Bopd
(353 Bopd net to AROC's revenue interest in the property) from 37 active
producers.  AROC has a 100% working interest in the field.  The estimated net
remaining reserves to AROC's interest in the field as of April 30, 2000 were
5,700 MBbls of oil.

Chittim Ranch Field, Texas.  The Chittim Ranch field is located in Maverick
County in southwest Texas.  AROC operates 6 active producing gas wells in the
field and has a working interest in approximately 12,800 acres, which is
partially under a farmout agreement with TXCO, Inc.  The field produces
principally from the Rodessa carbonates at a depth of 5,300 ft. with minor
production having been established in the Austin Chalk at a depth of 1,100 ft.
In April 2000 these 6 active wells produced at an average gross rate of 5 Bopd
and 0.7 MMcfgpd (3 Bopd and 0.4 MMcfgpd net to AROC's revenue interest in the
property).  The property was acquired in December 1999 and AROC's current
working interest in the property is approximately 82%.  The estimated net
remaining reserves to AROC's interest in the field as of April 30, 2000 were 63
MBbls of oil and 9,712 MMcf of gas.

Oakhill Field, Texas.  The Oakhill field is located in Gregg County in northeast
Texas.  The property was acquired in December 1999 and AROC currently owns a
100% working interest in the Grissom and Kuykendall leases covering an area in
excess of 225 acres in the Lake Cherokee area.  Production has not yet been
established on the leases and AROC is preparing to spud its first well on the
Grissom lease by Mid-October 2000.  The field is productive in the Cotton Valley
Formation in offset leases at a depth of approximately 11,000 ft.  Notably,
immediately to the south of the Grissom lease, Torch Operating Company has
recently completed a number of wells that had initial production rates in excess
of 2 MMcfgpd.  The estimated net remaining reserves to AROC's interest in the
field as of April 30, 2000 were 19 MBbls of oil and 6,444 MMcf of gas.

Black Warrior Basin Fields, Mississippi and Alabama.  AROC owns operated and
non-operated working interests in 83 wells (32 operated, 51 non-operated) and 12
non-operated royalty interests in Lamar, Fayette and Pickens Counties, Alabama
and Lee and Chickasaw Counties, Mississippi.  Production from these wells is
from multiple sandstone of Mississippian age at depths of 1,900 to 4,600 ft.
The fields produced at a combined average gross rate of 330 Bopd and 3.9 MMcfgpd
for the month of April 2000 (9 Bopd and 1.2 MMcfgpd net to AROC's revenue
interest in the properties).

                                       4
<PAGE>

AROC's working interest in the properties varies between 1.8% and 100%. The
estimated net remaining reserves to AROC's interest in these fields as of April
30, 2000 were 5 MBbls of oil and 8,931 MMcf of gas.

Tinsley Field, Mississippi.  The Tinsley field is located in Yazoo County,
Mississippi.  AROC operates 11 active producing or potentially productive oil
wells and 2 salt-water disposal wells in the field.  The field produces from
Upper Cretaceous age Eutaw Sandstones at a depth of approximately 4,500 ft.  In
April 2000 the field produced at an average gross rate of 92 Bopd (76 Bopd net
to AROC's revenue interest in the property) from 4 active producing wells.
Subsequent workover operations have boosted gross oil production to over 115
Bopd.  AROC's working interest in the property is 100%.  The estimated net
remaining reserves to AROC's interest in the field as of April 30, 2000 were 579
MBbls of oil.

Bolton Field, Mississippi.  The Bolton field is located in Hinds County,
Mississippi.  AROC operates 1 active producing well in the field.  The Ernest
Roberts G.U. #1 well is currently producing from Cotton Valley Formation
sandstones at a depth of approximately 16,000 ft.  In April 2000 the well
produced at an average gross rate of 31 Bopd and 1.1 MMcfgpd (23 Bopd and 0.8
MMcfgpd net to AROC's revenue interest in the property).  AROC's working
interest in the property as of April 30, 2000 was 91%.  The estimated net
remaining reserves to AROC's interest in the field as of April 30, 2000 were 122
MBbls of oil and 2,775 MMcf of gas.

South Elton Field, Louisiana.  The South Elton field is located in Jefferson
Davis Parish in southwest Louisiana.  AROC operates 7 active producing or
potentially productive oil and gas wells and 2 salt-water disposal wells in the
field.  This field produces principally from Oligocene age sandstone of the
Homeseekers C and D Formations at a depth of approximately 9,000 ft.  In April
2000 the field produced at an average gross rate of 106 Bopd (75 Bopd net to
AROC's revenue interest in the property).  Gas production has subsequently been
re-established and the field is now producing gas at a gross rate of
approximately 0.4 MMcfgpd (0.3 MMcfgpd net to AROC's revenue interest in the
properties).  Recent workover activities have increased gross oil production by
a further 20 Bopd.  AROC's current working interest in the properties is on
average approximately 97%.  The estimated net remaining reserves to AROC's
interest in the field as of April 30, 2000 were 221 MBbls of oil and 554 MMcf of
gas.

Jefferson Island Field, Louisiana.  The Jefferson Island field is located in
Iberia Parish in southwest Louisiana.  AROC currently has a 67% working interest
in a 525-acre lease that was farmed out to Continental Resources Inc. in 1998.
The first well under the farmout agreement was successfully drilled and
completed in September 1999 and AROC has a 33% working interest in the well and
the related unit.  The Continental JISMC #1well was productive in sandstones of
Siphoni Davisi age and in April 2000 was producing at an average gross rate of 6
Bopd and 0.9 MMcfgpd (2 Bopd and 0.2 MMcfgpd net to AROC's revenue interest in
the property).  If Continental drills and completes a second commercially
productive well, it will earn an additional one-third working interest in the
remainder of the lease. Several more locations remain to be drilled on the lease
and the estimated net remaining reserves to AROC's interest in the field as of
April 30, 2000 were 115 MBbls of oil and 552 MMcf of gas.

War-Wink South Field, Texas.  AROC owns a non-operated working interest in 47
active wells in the War-Wink South field, Ward County, Texas.  This field
produces from the Fusselman, Atoka, Wolfcamp and Cherry Canyon Formations at
depths ranging from 6,200 to 17,500 ft. In March 2000, these 47 active wells
produced at a combined average gross rate of 423 Bopd and 5.1 MMcfgpd (24 Bopd
and 0.4 MMcfgpd net to AROC's revenue interest in the properties).  AROC's
working interest in the properties is approximately 10%. The estimated net
remaining reserves to AROC's interest in the field as of April 30, 2000 were 92
MBbls of oil and 386 MMcf of gas.

In addition to these fields, AROC has other producing properties and associated
activities in the U.S.  Net proved reserves to AROC's interest in these
properties as of April 30, 2000 were 1,746 MBbls of oil and 7,961 MMcf of gas.

RESERVES

     Lee Keeling and Associates, Inc. (LKA), AROC's independent petroleum
engineering consulting firm, has made estimates of AROC's oil and gas reserves
at April 30, 2000.  LKA's report covers the estimated present value of future
net cash flows before income taxes (discounted at 10%) attributable to AROC's
estimated future net cash flows therefrom.

                                       5
<PAGE>

     The quantities of AROC's proved reserves of oil and natural gas presented
below include only those amounts which AROC 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 AROC's proved developed
reserves.  AROC's proved undeveloped reserves include only those quantities
which AROC reasonably expects to recover from the drilling of new wells based on
geological evidence from offsetting wells.  The risks of recovering these
reserves are higher from both geological and mechanical 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 AROC at April 30, 2000, as evaluated by LKA.

     The estimation of oil and gas reserves is a complex and subjective process
which is subject to continued revisions as additional information becomes
available.  Reserve estimates prepared by different engineers from the same data
can vary widely.  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
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 AROC's expected future cash flows or value of proved reserves.

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

     For further information on reserves, costs relating to oil and gas
activities, and results of operations from producing activities, see Note 16 to
the Consolidated Financial Statements--Supplementary Financial Information for
Oil and Gas Producing Activities (Unaudited) 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 AROC at April 30, 2000.  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 AROC has a working interest.  Net acres are the sum of AROC's
fractional interests owned in the gross acres.

     States in which AROC held developed and undeveloped acreage at April 30,
2000 include Alabama, Arkansas, Colorado, Kansas, Louisiana, Mississippi,
Montana, New Mexico, North Dakota, Oklahoma, Texas and Wyoming.

     $15.14 for oil and $2.29, $1.92, and $2.34 for gas, respectively.

(2)  No figures are included for U.K. production activities since first
     production started mid-August 1999.

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

     At April 30, 2000, AROC was participating in the drilling of one oil and
gas well.

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

TITLE TO PROPERTIES

     As is customary in the oil and gas industry, AROC 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 Company 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
Company cannot be predicted with certainty, management does not believe the
outcome of these lawsuits to have a material adverse effect on the financial
position, results of operations or liquidity of the Company.

ITEM 6.  SELECTED FINANCIAL DATA

     On May 1, 1997, the Company 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
company and so for accounting and financial reporting purposes, LaTex is treated
as having acquired the Company (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 the Company is April 30.

     On December 8, 1999, AROC acquired a majority of the shares of Alliance on
the basis of one share of AROC common stock for each ordinary share of Alliance,
with the result that the former shareholders of Alliance then held approximately
98% of the outstanding shares of AROC. Therefore, Alliance is deemed to have
acquired AROC for accounting purposes. The historical financial information for
all financial periods from April 30, 1997 to December 8, 1999 reflects the
results of operations and assets and liabilities of Alliance.

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

         The information in this "Management's Discussion and Analysis of
Financial Condition and Results of Operations" refers to the Consolidated
Financial Statements of AROC included in this Form 10-K which are presented in
accordance with U.S. 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, 2000 COMPARED TO THE YEAR ENDED APRIL 30, 1999

         Total revenues for the year ended April 30, 2000 were $12,505,885
compared to $6,234,477 for the year ended April 30, 1999. This 101% increase in
total revenues primarily resulted from an overall increase in production volumes
and realized prices during the year ended April 30, 2000 compared to the year
ended April 30, 1999. The increase in production volumes was mainly due to the
Company's U.K. properties which started first production during August 1999.
There was a 32% increase in the average sales price received for oil, and a 26%
increase in the average sales price received for natural gas. Crude oil
contributed 38% and natural gas contributed 62% of oil and gas production
revenues during the year ended April 30, 2000. For the year ended April 30,
1999, crude oil contributed 56% and natural gas contributed 44% of oil and gas
production revenues, respectively. The rise of natural gas from 44% of revenues
during 1999 to 62% during 2000 was also due to first sales from the Company's
U.K. properties.

         Lease operating expenses increased to $6,883,736 for the year ended
April 30, 2000, compared to $3,096,468 for the year ended April 30, 1999. The
increase in operating expenses is primarily a result of the U.K. properties

                                       13
<PAGE>

commencing production in August, 1999, increased workover expenses and higher
production taxes associated with improved sales volumes. On an equivalent barrel
basis, lease operating expenses, including severance tax, increased to $8.13 for
the year ended April 30, 2000, compared to $6.05 for the year ended April 30,
1999.

         General and administrative expenses for the year ended April 30, 2000
were $3,930,300 which represents an increase of 13% over the $3,486,007 incurred
in the prior fiscal year. This was primarily due to costs associated with
increased staff levels required to manage the additional properties acquired by
the Company prior to and subsequent to the year ended April 30, 2000. On an
equivalent barrel basis general and administrative expenses decreased by $2.17
to $4.64 for the year ended April 30, 2000 compared to $6.81 for the year ended
April 30, 1999.

         Depreciation, depletion and amortization expense increased 88% from
$1,670,711 for the year ended April 30, 1999 to $3,128,497 for the year ended
April 30, 2000. This was due primarily to higher production volumes. On an
equivalent barrel basis depreciation, depletion, and amortization increased
$0.42 to $3.69 for the year ended April 30, 2000, compared to $3.27 for the year
ended April 30, 1999.

         Ceiling test charges associated with the Company's U.K. Interests led
to an impairment charge of $28 million during the year ended April 30, 1999. Due
to continued low spot prices, the Company also recorded an aggregate impairment
charge of $2.5 million during the quarters ended July 31, 1999 and October 31,
1999. Since then, spot prices have improved and no additional impairment was
required during the remainder of the year ended April 30, 2000.

         Future quarterly full cost ceiling tests will be based on the then-
current prices for both natural gas and oil. The net carrying value of the
Company's U.K. natural gas properties has been reduced due to the full cost
ceiling limitation such that the present value of the Company's U.K. proved
natural gas reserves (discounted at 10 percent) does not exceed the Company's
net natural gas properties recorded in its balance sheet. There is a risk of
future property write-downs due to factors that negatively affect the estimated
present value of proved natural gas and oil reserves, including volatile natural
gas and oil prices, downward revision in estimated proved natural gas and oil
quantities, and unsuccessful exploratory operations.

         Interest expense for the year ended April 30, 2000 increased $4,175,847
from the year ended April 30, 1999. This was due to additional drawdowns from
the Company's credit facility with Bank of America to fund the East Irish Sea
Development. The EnCap debt issued during October 1998 to fund the acquisition
of the U.K Interests also was a reason for the increase in interest expense.
This debt only accrued interest during a six month period in the year ended
April 30, 1999, compared to a twelve month period in the year ended April 30,
2000. During December 1999, the Company completed several property acquisitions
with $6.5 million of additional EnCap debt which also caused increased interest
expense during the current fiscal year end.

         The net loss for the year ended April 30, 2000 was $10,973,789 ($0.21
per common share) compared to a net loss of $34,463,502 ($0.82 per common share)
for the year ended April 30, 1999.

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 17% decrease
in the average sales price received for oil, and a 25% 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.

                                       14
<PAGE>

         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.

         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. 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.

         AROC 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, development plans for the fields have become firmer, drilling results on
two 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 led to an impairment in
value of the U.K. Interests. The Company 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 had no impact on cash flows from operating
activities.

         Interest costs for 1999 increased $780,981, or 31%, from 1998 primarily
due to the revised credit facility put in place to fund the East Irish Sea
acquisition and development. In 1999, AROC wrote off $869,906 in deferred loan
costs related to the Company's previous credit facility.

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

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, 2000, AROC reported current assets of $3,228,603 and
current liabilities of $10,151,330, which resulted in a net current deficit of
$6,922,727.

         Operating activities of AROC used $857,936 during the year ended April
30, 2000, as compared to $3,991,251 used in net cash flow for the year ended
April 30, 1999.

         For the years ended April 30, 2000 and April 30, 1999, AROC's investing
activities used $10,650,721 and $24,174,756, respectively.

         Financing activities provided $11,796,326 for the year ended April 30,
2000, due primarily to proceeds from the issuance of long-term debt of
$12,639,118, offset by the payments of long-term debt of $567,670 and loan
acquisition costs of $275,122, compared to cash provided from financing of
$28,043,726 for the year ended April 30, 1999.

         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 carrying value of the Company's oil and gas properties.

         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 for the years ended April 30, 1998, 1999, and 2000 the Company
incurred losses of $4,728,923; $34,463,502; and $10,973,789, respectively and
continues to experience working capital deficits. Despite its negative cash
flow, the Company has been able to secure financing to support its ongoing
operations. As described in Note 5, the Company was not in compliance with
certain covenants of its loan agreements at April 30, 2000. As a result of the
replacement of the BoA Credit Agreement with the new Toronto Dominion Credit
Agreement and exchange of preferred stock for EnCap debt on May 2, 2000, these
covenant violations were no longer applicable. In addition, the Company obtained
a $17,000,000 subordinated loan from EnCap 1996 LP, ECIC, and El Paso with
interest of 12%, payable in kind to May 1, 2002. The new debt agreements
extended the repayment dates, originally scheduled to begin in October 2000, to
May 1, 2003. As a result of the May 2, 2000 transactions, the Company believes
it will be able to meet its obligations as they become due and to comply with
the terms of the new borrowing agreements. 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 the operator and approved by AROC. Currently,
there are material commitments for the 2001 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.

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.

         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, 2000                $17.35        $2.25
              Year ended April 30, 1999                $13.20        $1.79

         Between September 8, 1999 and February 10, 2000, the Company completed
several transactions with El Paso Merchant Energy to hedge approximately 30%-40%
of its existing monthly oil production by installing a floor of $19.00/barrel
(NYMEX WTI) and caps between $24.00/barrel and $26.65/barrel (NYMEX WTI). These
commodity price hedge arrangements will expire on December 31, 2000.

         On August 30, 1999, the Company completed a transaction with El Paso
Merchant Energy to hedge approximately 50% of its existing monthly U.S. gas
production by installing a floor of $2.40/MMBTU (NYMEX) and a cap of $3.00.
This commodity price hedge agreement will expire on October 31, 2000.  On March
31, 2000, the Company completed a transaction with El Paso to hedge
approximately 50% of its existing monthly U.K. gas production by installing a
floor of 10.5 pence/therm (IPE) and a cap of 12.55 pence/therm.  This commodity
price hedge agreement will expire on September 30, 2000.

NEW ACCOUNTING PRONOUNCEMENTS

         Statement of Financial Accounting Standards No. 133, "Accounting for
Derivatives Instruments and Hedging Activities" (Statement 133) was issued by
the FASB in June 1998.  Statement 133 standardizes the accounting for derivative
instruments, including certain derivative instruments embedded in other
contracts.  Under the standard, entities are required to carry all derivative
instruments in the balance sheet at fair value.  The accounting for changes in
the fair value of a derivative instrument depends on whether it has been
designated and qualifies as part of a hedging relationship and, if so, on the
reason for holding it.  If certain conditions are met, entities may elect to
designate a derivative instrument as a hedge of exposures to changes in fair
values, cash flows, or foreign currencies.  If the hedge exposure is a fair
value exposure, the gain or loss on the derivative instrument is recognized in
earnings in the period of change together with the offsetting loss or gain on
the hedged item attributable to the risk being hedged.  If the hedged exposure
is a cash flow exposure, the effective portion of the gain or loss on the
derivative instrument is reported initially as a component of other
comprehensive income (outside earnings) and subsequently reclassified into
earnings when the forecasted transaction affects earnings.  Any amounts excluded
from the assessment of hedge effectiveness as well as the ineffective portion of
the gain or loss is reported in earnings immediately.  Statement 133 was amended
by Statement No. 137 in June 1999 which delayed implementation until fiscal
years beginning after June 15, 2000, with early adoption permitted.  The Company
is not required to adopt this pronouncement until fiscal year ended April 30,
2002.  The Company believes the impact of adopting Statement 133 will not be
significant.

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 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, 2000, the Company's debt, including interest on the subordinated
debt, consists of $50,601,851 in borrowings under its BoA Credit Agreement which
bear interest at a variable rate, and $18,043,539 in borrowings under its 10%
Senior Subordinated Notes which bear interest at a fixed rate. The Company
hedged 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 made interest payments on its BoA Credit
Agreement as scheduled and received or made payments based on the differential
between the fixed rate of the swap and a floating rate plus a defined
differential. These instruments reduced 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. This hedge expired on March 31, 2000. The
Company currently has no instruments in place. A hypothetical increase in
interest rates of two percentage points in variable rate debt would cause an
increase in

                                       17
<PAGE>

interest expense of $440,000 during the 2001 fiscal year, assuming that variable
rate outstanding borrowings under the Toronto Dominion Credit Agreement (see
Recent Developments) remain at current levels.

         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 floors and
caps. 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 April 30,
2000, the Company had entered into derivative commodity hedges covering an
aggregate of 132,500 barrels of oil and 1,250,000 MMBTU's of gas that extended
through December 2000 (oil) and October 2000 (gas). 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 floor and cap 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, 2000, would cause a loss in income and cash flows of approximately
$2,400,000 during the 2001 fiscal year, 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.

Board of Directors
AROC Inc. and Subsidiaries


We have audited the consolidated balance sheets of AROC Inc. and subsidiaries as
of April 30, 1999 and 2000, and the related consolidated statements of
operations, stockholders' equity (deficit) and comprehensive income, and cash
flows for each of the years in the three-year period ended April 30, 2000. 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 auditing standards generally accepted
in the United States of America.  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 AROC
Inc. and subsidiaries as of April 30, 1999 and 2000 and the results of their
operations and their cash flows for each of the years in the three-year period
ended April 30, 2000 in conformity with accounting principles generally accepted
in the United States of America.

                  Notes to Consolidated Financial Statements


(1)  Organization and Summary of Significant Accounting Policies

     Organization and basis of presentation

     AROC Inc. (AROC or the Company) is a Tulsa-based 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.
     Oil and gas production operations are currently conducted principally in
     Oklahoma, Texas, Louisiana, Mississippi, Alabama, Arkansas, New Mexico, and
     the United Kingdom.  Included in oil and gas revenues are sales from 10
     significant producing properties, which aggregated approximately
     $2,210,000, $2,155,000, and $6,946,000, for the years ended April 30, 1998,
     1999, and 2000, respectively.

     In these financial statements, the Company refers to AROC and its
     subsidiaries for periods ending on or after December 9, 1999 and to
     Alliance Resources PLC and its subsidiaries for periods ending on or before
     December 8, 1999 (see Note 2).   These financial statements are prepared in
     accordance with generally accepted accounting principles in the United
     States.

     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 for the years ended April 30, 1998, 1999, and 2000 the Company
     incurred losses of $4,728,923;  $34,463,502; and $10,973,789, respectively
     and continues to experience working capital deficits.   Despite its
     negative cash flow, the Company has been able to secure financing to
     support its ongoing operations.  As described in Note 5, the Company was
     not in compliance with certain covenants of its loan agreements at April
     30, 2000.  As a result of the replacement of the BoA Credit Agreement with
     the new Toronto Dominion Credit Agreement and exchange of preferred stock
     for EnCap debt on May 2, 2000, these covenant violations were no longer
     applicable.  In addition, the Company obtained a $17,000,000 subordinated
     loan from EnCap affiliates, with interest of 12%, payable in kind to May 1,
     2002. The new debt agreements extended the repayment dates, originally
     scheduled to begin in October 2000, to May 1, 2003.  As a result of the May
     2, 2000 transactions, the Company believes it will be able to meet its
     obligations as they become due and to comply with the terms of the new
     borrowing agreements.  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, AROC (Texas), Inc., and Source Petroleum Inc.  Transactions
     are conducted primarily in U.K. Sterling and U.S. dollars. Managements
     considers the U.S. dollar the functional currency of the Company and the
     Company's consolidated financial statements have been prepared in U.S.
     dollars.

     Consolidation

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

             Notes to Consolidated Financial Statements, Continued


     Loss Per Share

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

     The effect of potential common shares (warrants) is anti-dilutive.
     Accordingly, diluted loss per share is not presented.

     Foreign Currency Translation

     The financial statements of subsidiaries of the Company whose functional
     currency is not U.S. dollars are translated for consolidation purposes at
     the rate of exchange 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 U.S.
     dollars at the exchange rate prevailing at the balance sheet date. Any
     exchange gain or loss is recorded in the consolidated statements of
     operations.

     Revenues

     Revenues represent income from production and delivery of oil and gas,
     recorded net of royalties in kind. The Company follows the sales method of
     accounting for gas imbalances.  A liability is recorded only if the
     Company's takes of gas volumes exceed its share of estimated recoverable
     reserves from the relevant well.  No receivables are recorded for those
     wells where the Company has taken less than its ownership share of gas
     production.

     Oil and Gas Properties

     The Company 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 Company 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 discounting and using prices and cost levels at the
     balance sheet date.

             Notes to Consolidated Financial Statements, Continued


     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.

     Leases

     Rentals under operating leases are charged to the consolidated statements
     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
     statements of operations as they occur.

     The Company's criteria for a derivative instrument to qualify for hedge
accounting treatment are as follows:
       --the timing or duration and characteristics of the underlying exposure
         must have been identified;
       --changes in the value of the derivative must highly correlate with
         changes in the value of the exposure;
       --the derivative has been designated as a hedge of a specific asset,
         liability or anticipated transaction; and
       --the derivative instrument reduces exposure to fluctuations caused by
         movements in commodity prices, currency exchange rates, or interest
         rates.

     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.

     Cash Flow Statement

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

     Stock Option Plan

     The Company applies the intrinsic value-based method of accounting
     prescribed by Accounting Principles Board ("APB") Opinion No. 25,
     "Accounting for Stock Issued to Employees," and related interpretations, in
     accounting for its fixed plan stock options.  As such, compensation expense
     would be recorded on the date of grant only if the current market price of
     the underlying stock exceeded the exercise price.  Financial Accounting
     Standards Board Statement ("FAS") 123, "Accounting for Stock-Based
     Compensation," established accounting and disclosure requirements using a
     fair value-based method of accounting for stock-based employee compensation
     plans.  As allowed by FAS 123, the Company has elected to continue to apply
     the intrinsic value-based method of accounting described above, and has
     adopted the disclosure requirement of FAS 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 Company considers itself to be involved in one business activity and
     does not meet the criteria established by Financial Accounting Standards
     Board Statement FAS 131, "Segment Disclosures and Related Information".

     Comprehensive Income (Loss)

     The Company follows FAS 130, "Reporting Comprehensive Income" which
     established standards for reporting and display of comprehensive income and
     its components in a full set of general-purpose financial statements.  The
     components of total comprehensive income (loss) for the periods consist of
     net losses and foreign currency translation adjustments.

(2)  Acquisitions

     (a)  American Rivers

     On December 8, 1999, American Rivers Oil Company, a Wyoming corporation
     (American Rivers) merged into the subsidiary of a new Delaware holding
     company, and the new Delaware holding company (New Alliance) subsequently
     acquired all of the shares of Alliance Resources PLC (Alliance). In the
     reincorporation, each shareholder of American Rivers received 0.11 shares
     of New Alliance, par value $0.001 per share, for each share of common stock
     or Class B common stock of American Rivers, resulting in the issuance of
     1,191,695 shares of New Alliance common stock. New Alliance acquired all of
     the outstanding ordinary shares of Alliance on the basis of one share of
     New Alliance common stock for each ordinary share of Alliance, resulting in
     the issuance of 47,487,142 shares of New Alliance common stock.

             Notes to Consolidated Financial Statements, Continued


     In connection with the reincoporation, restricted convertible shares of
     Alliance were exchanged for 10,000,000 convertible restricted voting shares
     of New Alliance, which may be converted into up to 20,000,000 shares of New
     Alliance's common stock dependent on the achievement of sales production
     levels from certain U.K. interests.  Further, in exchange for convertible
     subordinated unsecured loan notes ($1,550,700) convertible into 1,193,581
     ordinary shares of Alliance, New Alliance issued warrants to subscribe for
     1,193,581 shares of New Alliance common stock.  Also, in exchange for
     warrants to subscribe for 5,079,149 ordinary shares of Alliance, New
     Alliance issued warrants to subscribe for 5,079,149 shares of New Alliance
     common stock.

     The Alliance shareholders received approximately 98% of the total common
     shares of New Alliance and the American Rivers shareholders received
     approximately 2% of the total common shares of New Alliance.  As the
     Alliance shareholders own approximately 98% of the combined company,
     Alliance was treated as having acquired American Rivers for accounting
     purposes.  Following reincorporation, New Alliance was renamed AROC Inc.
     The historical financial statements prior to December 8, 1999 are those of
     Alliance, which has been restated for the equivalent number of shares
     received in the merger.

     The assets and liabilities of American Rivers at the date of acquisition
     are as follows:

                         Cash                      $     853
                         Oil and gas properties       17,552

                                                ============

     In addition, transaction costs of approximately $665,000 were incurred by
     the Company and charged directly to equity.  The consolidated condensed
     statements of operations include the results of operations of American
     Rivers from the date of the acquisition.  Pro forma information giving
     effect to the transaction is not presented because the operations of
     American Rivers prior to the acquisition were nominal.

     (b)  Difco Limited and U.K. Interests

     On October 30, 1998, the Company completed its acquisition of Difco Limited
     ("Difco").  The Company 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 oil and gas reserves related to the U.K. Interests.  The shares
     issued represented approximately 8.7% of the outstanding shares of the
     Company.  The former Difco shareholders could receive up to approximately
     27% 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.  Alliance
     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.

     (c) 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 "Alliance Shares") and
     warrants to purchase an additional 1,927,908 Alliance Shares.

     The purchase price of Alliance 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 Alliance assets and liabilities of the acquired
     business at the date of acquisition was as follows:

          Cash                                                    $ 1,460,555

     In connection with the acquisition, Alliance issued to Bank of America, the
     Company's principal lender, 156,250 Alliance Shares and convertible
     subordinated unsecured loan notes convertible into 115,456 Alliance Shares
     to settle fees of $203,000 and $150,000 payable upon restructuring of
     LaTex's bank debt, respectively.  In addition the Company issued 100,000
     Shares to Rothschild Natural Resources, LLC in settlement of outstanding
     fees of $150,000.

     Alliance also issued 1,343,750 common shares, subordinated unsecured loan
     notes convertible into 1,078,125 common shares and 1,210,938 warrants to
     Bank of America in exchange for an overriding royalty interest in most of
     LaTex's properties held by Bank of America.

     The purchase price was allocated to oil and gas properties and has been
     arrived at as follows:

          Value of 1,343,750 ordinary shares and warrants          $2,371,300
          Value of convertible subordinated unsecured loan note     1,400,700
                                                                   ----------

(3)  Impairment of U.K. Interests

     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.  The Company does not
     have contracts in place with purchasers and, accordingly, utilizes the spot
     market price to value such interests. The utilization of these factors has
     resulted in ceiling test

</TABLE>

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

     The Company has net operating loss carryovers to offset future taxable
     earnings of approximately $65 million, of which approximately $58 million
     of losses are 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 2020.

     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 was $18,500,000 and
     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 2.0%, or
     (ii) 2.5% above the current London Interbank Offered Rate (7.4% and 8.9% at
     April 30, 1999 and 2000, respectively).  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 the 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 (i)
     BoA's Tranche B reference rate plus 2.0%, or (ii) 4.0% above the current
     London Interbank Offered Rate (8.9% and    10.29% at April 30, 1999 and
     2000, respectively).  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 July
     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
     London Interbank Offered Rate (11.9% and

     13.29% at April 30, 1999 and 2000, respectively). 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, which was in the amount of $18,043,539, including interest at
     10%, was unsecured.  Interest was payable quarterly and principal was due
     in full on October 30, 2005.  Until October 30, 2001, the Company had 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 agreed to 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.  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 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 until March 31, 2000 (see Note 13).

     During 1998, in connection with the issuance of the EnCap debt, the Company
     sold EnCap 15,000,000 common 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.

     On December 21, 1999, AROC acquired various properties by issuing three
     separate notes currently held by EnCap and Picosa Creek Limited Partnership
     (collectively EnCap II) for an aggregate of $6,500,000 at an interest rate
     of 10% per annum.  The notes were scheduled to mature on October 29, 2005
     with interest payable on the last business day of each quarter.  Until
     January 1, 2003, the Company had the option, in lieu of paying cash, of
     increasing the principal amount of the debt by the interest due.

     As of April 30, 2000, the Company was not in compliance with certain
     covenants of the BoA Credit Agreement, which included but were not limited
     to the maintenance of minimum levels of working capital and interest
     coverage.  As a result of the replacement of the BoA Credit Agreement with
     the Toronto Dominion Credit Agreement on May 2, 2000, these covenant
     violations were no longer applicable. (See Note 15--for subsequent event
     regarding refinancing and debt conversion to preferred stock.)

     The Company capitalizes interest cost as a component of the North Sea U.K.
     Interests development program. The following is a summary of interest cost
     incurred:

(6)  Savings and Profit Sharing Plan

     The Company maintains an employee savings and profit sharing plan (the
     Plan) which covers substantially all of its employees.  The Plan is
     comprised of a 401(k) saving portion and a noncontributory defined
     contribution portion.  Employees are qualified to participate after
     approximately 30 days of service.  Participation in the 401(k) plan is
     voluntary, and the Company matches contributions up to six percent of the
     employees' salary at a rate of 50 percent of the employee's contribution.
     The Company contributed $9,243, $17,523, and $30,835 to the Plan during the
     years ended April 30, 1998, 1999, and 2000, respectively.

     The noncontributory portion of the Plan allows the Company to share annual
     profits with employees.  Annual payments to the Plan are elective.
     Management elected to make no contributions to the Plan for the years ended
     April 30, 1998, 1999, and 2000.  The Company is under no obligation to make
     contributions to the Plan in the future.

(7)  Capital Stock

     On December 8, 1999, AROC acquired a majority of the shares of Alliance on
     the basis of one share of AROC common stock for each ordinary share of
     Alliance, with the result that the former shareholders of Alliance then
     held approximately 98% of the outstanding share of AROC. Therefore,
     Alliance is deemed to have acquired AROC for accounting purposes. The
     historical financial information for all financial periods prior to
     December 8, 1999, reflects the results of operations and assets and
     liabilities of Alliance. The Alliance shares have been retroactively
     restated for the equivalent number of shares received in the merger.

     The Company issued convertible restricted stock in connection with the
     Difco acquisition (see Note 2).  Each convertible restricted share is
     entitle to one-half vote on all matters in which the common shares are
     entitled to vote and have rights identical to the common shares except for
     certain restrictions on transfer.  In addition, the holders of the
     convertible restricted shares have contingent right to acquire up to
     20,000,000 common shares prior to 2003.  The number of common shares
     actually issued is a result of this contingent right will depend on the
     sales production actually achieved, or the estimated value attributable to
     the U.K. Interests.  The convertible restricted shareholders will receive
     only 5,000,000 common shares if none of the production targets or reserve
     values are achieved.

(8)  Stock and Incentive Plan

     During the year ended April 30, 2000, the Company adopted the 2000 Omnibus
     Stock and Incentive Plan (the Stock Plan).  This plan is intended to
     provide additional incentives through the award of options, stock
     appreciation rights, shares of restricted stock, and performance awards to
     directors, officers, key employees and consultants.

     During the year ended April 30, 2000, the Company granted 6,600,000 shares
     of restricted stock to the directors, officers and certain key employees.
     Under the Stock Plan, the shares vest in equal increments in April 2001,
     2002, and 2003 or upon a change in control of the Company as defined in the
     Stock Plan.  The estimated market value of shares awarded was $858,000.
     This amount was recorded as unearned compensation-restricted stock and is
     shown as a separate component of stockholders' equity.  Unearned
     compensation will be amortized to expense over the three year vesting
     period.

     As of April 30, 1999, there were options to subscribe to 3,102,500 shares
     with a weighted average service price of 17.2p which were cancelled in
     December 1999.

(9)  Warrants

     During the year ended April 30, 2000, the Company issued warrants to
     subscribe for 5,079,149 common shares with various strike prices in
     exchange for the then outstanding warrants to subscribe for ordinary shares
     in Alliance.


     The following is a summary of warrants outstanding as of April 30, 2000:

</TABLE>

     At April 30, 1999, 5,079,149 warrants to subscribe for Alliance ordinary
     shares were outstanding.

(10) Convertible Subordinated Unsecured Loan Notes

     At April 30, 1999, the Company had outstanding loan notes of $1,550,000
     convertible into 1,193,581 common shares (see Note 2).  The loan notes,
     which were non-interest bearing, were convertible by the holders (on the
     payment of a nominal cash consideration) any time up to ten years following
     their date of issue. They were 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 were to be repaid on that
     date at an amount equal to twice the amount paid up on the notes.  In
     connection with the American Rivers acquisition (see Note 2), all
     outstanding loan notes were converted into warrants to subscribe to
     1,193,581 common shares at a price of $0.01 per share

(11) Contingencies and Commitments

     The Company 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
     Company cannot be predicted with certainty, management does not believe the
     outcome of these lawsuits will have material adverse effect on the
     financial position, results of operations or liquidity of the Company.

     The Company leases office space and certain property and equipment under
     various lease agreements.  As of April 30, 2000, future minimum lease
     commitments were approximately as follows:

     Rent expense under all operating leases was $252,627, $251,447, and
     $225,041 during the years ended April 30, 1998, 1999, and 2000,
     respectively.

(12) Related Party Transactions

     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 Managing Director of Alliance.  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.

     The Company currently has entered into several energy derivative
     transactions with El Paso Merchant Energy, a subsidiary of El Paso Energy
     (El Paso).  Affiliates of El Paso are also significant stockholders of the
     Company (see Note 13).

(13) Financial Instruments and Derivatives

     The Company uses oil and gas floor and cap contracts and interest rate
     protection agreements to reduce its exposure to fluctuations and in the
     prices of crude oil and natural gas and in interest rates.  Derivative
     instruments give rise to credit risk due to possible non-performance by the
     counterparties.  However, through ongoing controls, AROC maintains the
     credit worthiness of its counterparties.

     (a)  Oil and Gas

     Effective May 15, 1997, the Company terminated a previously existing oil
     and gas pricing derivative at a cost of $1,128,000 settled by an increase
     in the BoA credit facility. The loss relating to the buy-out was recognized
     in its entirety during the year ended April 30, 1998.

     On October 23, 1997, the Company 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 Company, and
     the associated premium cost ($385,680) was funded by additional drawdowns
     under the BoA credit facility.  The commodity price hedges covered 32,000
     bbls and 100,000 MMBTUs per month for the year ended October 31, 1998
     (covered in excess of 90% of the Company'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 Company's
     commodity price hedge agreements expired.

     During February 1999, the Company completed a transaction with El Paso
     Merchant Energy 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).  In Addition, during April 1999, the Company completed
     a transaction with El Paso Merchant Energy to hedge approximately 40% of
     its existing monthly oil production by installing a floor of $12.00/barrel
     (NYMEX WTI).  These commodity price hedge agreements expired on October 31,
     1999.

     Between September 8, 1999 and February 10, 2000, the Company completed
     several transactions with El Paso Merchant Energy to hedge approximately
     30%-40% of its existing monthly oil production by installing a floor of
     $19.00/barrel (NYMEX WTI) and caps between $24.00/barrel and $26.65/barrel
     (NYMEX WTI).  These commodity price hedge arrangements will expire on
     December 31, 2000.

             Notes to Consolidated Financial Statements, Continued


     On August 30, 1999, the Company completed a transaction with El Paso
     Merchant Energy to hedge approximately 50% of its existing monthly U.S. gas
     production by installing a floor of $2.40/MMBTU (NYMEX Natural Gas) and a
     cap of $3.00.  This commodity price hedge agreement will expire on October
     31, 2000.  On March 31, 2000, the Company completed a transaction with El
     Paso to hedge approximately 50% of its existing monthly U.K. gas production
     by installing a floor of 10.5 pence/therm (IPE) and a cap of 12.55
     pence/therm.  This commodity price hedge agreement will expire on September
     30, 2000.

     (b)  Interest

     The Company was required, by agreement with BoA (see Note 5) to participate
     in an interest rate protection program (swaps), for interest on the debt
     payable to BoA until March 31, 2000.  Interest was hedged to achieve a
     fixed rate of 7.49%  calculated on a monthly basis based on the related
     debt fixed amortization schedule.  Hedging gains/losses are included in
     interest expense.

     (c) Fair Value of Financial and Commodity Instruments

     The following methods and assumptions were used by the Company in
     estimating the fair value of its financial and commodity instruments.  The
     reported amounts of cash equivalents, accounts receivable and payable
     approximate fair value due to their short-term maturity.  The carrying
     value of the Company's floating rate debt approximated fair value and the
     value of the fixed rate debt is estimated based on comparable debt rates.
     The fair value of commodity derivatives are based on quoted market prices.

     The estimated fair value of long-term debt is based primarily on comparable
     market rates for the same or similar issues as advised by the noteholders
     (see Note 5).  The fair value of forward exchange and currency option
     contracts is based on current market rates of comparable instruments.

(14) Disposition of Oil and Gas Properties

     During the years ended April 30, 1998, 1999, and 2000, the Company sold oil
     and gas properties for approximately $5,600,000, $1,742,000, and $ 411,000,
     respectively.  Proceeds of such sales were credited to the full cost pool.

(15) Subsequent Events

     Effective May 1, 2000, AROC designated 2,200,000 shares of its authorized
     preferred stock as Series A Preferred Stock.  The Series A Preferred Stock
     accrues cumulative dividends at the rate of $5.00 per share per year,
     payable semiannually.  Until May 1, 2002, dividends are payable in kind
     through the issuance of additional shares of preferred stock at a price
     equal to the fair market value of the preferred stock at the time of

     the payment. The preferred stock has a liquidation preference of $50.00 per
     share and may be redeemable at $50.00 per share at either the Company's or
     the holder's option upon the occurrence of certain events. Each share of
     preferred stock is convertible at any time into 384.6 shares of the
     Company's common stock and has the right to vote in all matters on the same
     basis as if the preferred stock had been converted into common stock. The
     terms of the preferred stock prohibit the Company from taking certain
     actions without the consent of the holders of the preferred stock.

     On May 2, 2000, the Company sold to BoA, EnCap Equity 1996 Limited
     Partnership ("EnCap 1996 LP"), Energy Capital Investment Company PLC
     ("ECIC"), El Paso Capital Investments, L.L.C. (El Paso), EF-II Holdings,
     LLC (EF-II), Picosa Creek Limited Partnership (Picosa) and EnCap
     Investments, L.L.C. (EnCap Investments) 850,163 shares of the Company's
     newly created Series A Preferred Stock for a total consideration of
     approximately $42.5 million, received in satisfaction of outstanding
     obligations to those parties and in consideration of cash (approximately
     $2,700,000) and the purchase of an oil and gas property interest (valued at
     approximately $2,500,000).

     Also on May 2, 2000, pursuant to four separate Purchase and Sale Agreements
     by and between (i) EnCap Equity 1994 Limited Partnership (EnCap 1994 LP),
     (ii) ECIC and ECIC Corporation, (iii) EnCap 1996 LP, and (iv) Mountaineer
     Limited Partnership, and the Company, the Company also acquired direct or
     indirect ownership of oil and gas properties having a net present value,
     discounted at 10%, of approximately $62 million at May 1, 2000, using non-
     escalated prices of $2.50 per mcf of gas and $22.00 per barrel of oil.  The
     properties include approximately 280 wells located in Texas, Louisiana, New
     Mexico, and Wyoming.  The properties were acquired in exchange for the
     issuance to the sellers of an aggregate of 930,140 shares of the Company's
     Series A Preferred Stock.

     In addition, on May 2, 2000, the Company entered into a Purchase Agreement
     providing for the sale to EnCap 1996 LP, ECIC and El Paso of a total of
     $17,000,000 in subordinated notes in exchange for cash in that amount.  The
     subordinated notes bear interest at the rate of 12% per year, payable
     semiannually.  Principal is due May 1, 2007.  Until May 1, 2002, interest
     is payable in kind by increasing the principal amount of the debt.
     Additionally, the Company also issued to EnCap 1996 LP, ECIC and El Paso
     warrants to purchase a total of 39,541,233 shares of the Company's common
     stock at a price of $0.01 per share at any time until April 30, 2007
     pursuant to such Purchase Agreement.

     As a result of these transactions, the Company has outstanding 55,278,837
     shares of common stock, 10,000,000 convertible restricted voting shares,
     warrants to purchase 45,813,963 shares of common stock, and 1,780,303
     shares of Series A Preferred Stock that are convertible into an aggregate
     of 684,731,923 shares of common stock.  EnCap 1996 LP, EnCap 1994 LP, ECIC,
     EnCap Investments, Picosa, EF-II and El Paso have the right to vote in the
     aggregate approximately 80% of the Company's voting securities and Bank of
     America and its affiliates have the right to vote approximately 11.6% of
     the Company's voting securities.

     Pursuant to a Credit Agreement dated as of May 1, 2000, among AROC, Toronto
     Dominion (Texas), Inc., individually and as Agent, and the lenders named in
     that agreement (the TD Credit Agreement), the Company obtained a new
     $35,000,000 credit facility.  The credit facility is secured by a first
     lien on substantially all of the Company's assets and the credit facility
     imposes certain restrictions on the Company's activities, including the
     payment of dividends and purchases of stock.  The credit facility provides
     for a revolving line of credit for three years.  Borrowings under the
     credit facility bear interest at either the LIBOR rate plus from 1.75% to
     3.0% or the agent's prime rate plus from .25% to 1.5%, at the Company's
     election.  Interest is payable quarterly beginning July 31, 2000.
     Principal is payable in full on the third anniversary of the closing of the
     credit facility. The borrowing base for the credit facility will typically
     be redetermined semiannually, although the lenders and borrowers have the
     right to make a redetermination at any time.

     A portion of the proceeds of the cash received from the credit facility and
     the sale of the subordinated debt were used to satisfy the Company's
     obligations under its previous credit facility with BoA and the remainder
     will be used for working capital.

     Estimated Quantities of Proved Oil and Gas Reserves

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

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

     United Kingdom Revisions of previous estimates amounts, noted above, are
     attributable to several fields being considered uneconomic based on prices
     at April 30, 1999.  With the increase in prices during the year ended April
     30, 2000, these fields were considered economic at April 30, 2000.

     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 Company'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.
