           Cautionary Statement Regarding Forward Looking Statements

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

A.   Summary of Significant Accounting Policies

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

These financial statements have been prepared by AROC Inc. (AROC or the Company)
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission, and reflect all adjustments which are, in the opinion of
management, necessary for a fair statement of the results for the interim
periods, on a basis consistent with the annual audited financial statements.
All such adjustments are of a normal, recurring nature.  Certain information,
accounting policies, and footnote disclosure normally included in financial
statements prepared in accordance with generally accepted principles have been
omitted pursuant to such rules and regulations, although the Company believes
that the disclosures are adequate to make the information presented not
misleading.  These financial statements should be read in conjunction with the
AROC, EnCap Acquisition and Pro Forma financial statements and the notes thereto
included in the Company's most recent Form 8-K.

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.

Loss Per Share
--------------

Basic loss per share has been computed by dividing the net loss attributable to
common stockholders by the weighted average number of common shares and
convertible shares (convertible at any time into a minimum of 5,000,000 common
shares) outstanding during the periods presented.

The effect of potential common shares (options, warrants and restricted stock)
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.  Translation and exchange gains or
losses for the periods presented were immaterial.

                                  (Unaudited)


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.

For the periods presented and at September 30, 2000, the Company had net
deferred tax assets reduced by a valuation allowance to zero because it was not
more likely than not such deferred tax assets will be realized.

Debt Issuance Costs
-------------------

Debt issuance costs are initially capitalized and are amortized (interest
method) over the term of the debt to which they relate.

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 requirements of FAS 123.

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".

Revenues from operations from the United Kingdom (UK) production were $371,583
and $673,590 for the three and nine months ended September 30, 2000,
respectively. Loss from operations from the UK production were $332,748 and
$345,477 for the three and nine months ended September 30, 2000, respectively.
Capital expenditures were $1,311,766 for the three months and $1,680,766 for the
nine months ended September 30, 2000.  The UK oil and gas properties were
acquired in May 2, 2000 in connection with the old AROC reverse acquisition (see
note B).

B.   Significant Events

     As a result of the May 2, 2000 transactions described below, EnCap Equity
1996 Limited Partnership (EnCap 1996 LP) became the largest stockholder
(approximately 39%) of AROC Inc. (old AROC). Although old AROC is the legal
acquirer, EnCap 1996 LP is treated as having acquired old AROC for accounting
purposes. Accordingly, the transactions have been accounted for as a reverse
acquisition and EnCap 1996 LP is now referred to as AROC or the Company. The
historical financial statements are those of EnCap 1996 LP, which have been
restated for the equivalent number of shares received in the transactions. The
results of operations of AROC (Legal Acquirer) will be included in the financial
statements of the combined AROC and EnCap 1996 LP financial statements from May
2, 2000 (Acquisition Date).

On May 2, 2000, pursuant to four separate Purchase and Sale agreements by and
between old AROC and (i) EnCap Equity 1994 Limited Partnership (EnCap 1994 LP),
(ii) Energy Capital Investment Company PLC (ECIC) and ECIC Corporation, (iii)
EnCap 1996 LP, and (iv) Mountaineer Limited Partnership (together the Sellers),
old AROC acquired direct or indirect ownership of oil and gas properties located
in Texas, Louisiana, New Mexico and Wyoming    (the EnCap Acquisition).  The
properties were acquired in exchange for the issuance to the Sellers of an
aggregate of 930,140 shares of the Company's newly created redeemable Series A
Preferred Stock (Preferred Stock).

Also, on May 2, 2000, old AROC sold to Bank of America, EnCap 1996 LP, 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 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 $2,000,000).

The 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 AROC'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 AROC'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
AROC from taking certain actions without the consent of the holders of the
Preferred Stock.  Upon the first to occur of (1) an event of default, as
defined, or (2) May 1, 2005, each holder of a share of Preferred Stock shall be
entitled to require that AROC redeem all

of the Preferred Stock held by such holder by paying in cash the redemption
price ($50.00 per share plus unpaid dividends). The charge to stockholders'
equity of $28,243,708 for the issuance of Preferred Stock represents the
difference between fair value ($50 per share) of Preferred Stock issued by old
AROC to acquire oil and gas properties from EnCap 1996 LP and the historical
cost of those oil and gas properties as EnCap 1996 LP is the accounting
acquirer.

Pursuant to a Credit Agreement dated as of May 2, 2000, among AROC, Toronto
Dominion (Texas), Inc., individually and as Agent, and the lenders named in that
agreement (the "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. 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.

In addition, on May 2, 2000, old AROC 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,
old AROC also issued to EnCap 1996 LP, ECIC and El Paso warrants to purchase a
total of 39,541,233 shares of AROC's common stock at a price of $0.01 per share
at any time until April 30, 2007 pursuant to such purchase agreement.  The fair
value of the warrants ($4,744,948) relating to the subordinated notes has been
treated as a discount.

After these transactions, AROC 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 Redeemable
Preferred Stock that are convertible into an aggregate of 684,731,923 shares of
common stock.

Old AROC had a fiscal year-end of April 30 while EnCap 1996 LP has a December 31
year-end.  As a result of these transactions, the combined entity has adopted a
December 31 year-end.

The Company is engaged in the exploration, development, production and operation
of oil and gas properties.  Operations are primarily conducted in Texas,
Louisiana, New Mexico, Wyoming, Oklahoma, Mississippi, Alabama, Arkansas and the
United Kingdom.

The fair value of the assets and liabilities of the acquired businesses (EnCap
Acquisition and AROC) at May 2, 2000 is as follows (in thousands):

Cash                                                $    578
Other current assets                                   2,654
Other assets                                             145
Property, plant and equipment                         97,224
Long-term debt                                       (68,645)
Current liabilities                                  (10,151)
                                                  ----------
       Net purchase price                           $ 21,805
                                                  ==========

The net purchase price includes $21,097,000 for EnCap Acquisition (interests in
certain oil and gas properties) and $708,000 for old AROC. The EnCap Acquisition
properties were acquired in exchange for preferred stock as described above. The
old AROC acquisition represents the purchase step-up resulting from the reverse
acquisition (discussed in note A) of the remaining 80% of old AROC common stock
not already owned by EnCap Equity 1996 LP. The purchase price (step-up) was
based on the equivalent common stock value ($0.13 per share) of the Series A
Redeemable Preferred Stock discussed above. The net purchase price was allocated
to the acquired assets and liabilities based on their relative fair values.

     The following summarized unaudited pro forma results of operations for the
nine months ended September 30, 2000 and 1999, assumes that the May 2, 2000: (i)
reverse acquisition of AROC Inc. (legal acquirer) by EnCap 1996 LP (accounting
acquirer), (ii) the acquisition of interests in oil and gas properties (EnCap
Acquisition) and (iii) the refinancing of AROC debt, all occurred as of January
1, 1999.  The information is presented in thousands with the exception of the
per share information.

C.   Stock Incentive Plan

In April, 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. None were issued during the period ended September 30, 2000.

In April, 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.

E.   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.

   Three Months Ended September 30, 2000 compared to the Three Months Ended
   ------------------------------------------------------------------------
                              September 30, 1999
                              ------------------

Total revenues from the Company's operations for the quarter ended September 30,
2000 were $5,696,624 compared to $957,075 for the quarter ended September 30,
1999.  Revenues increased significantly over the comparable period a year
earlier due principally to higher oil and gas prices and production from oil and
gas properties acquired in the May 2, 2000 transactions described earlier.

Total operating expenses increased to $4,868,739 for the quarter ended September
30, 2000 compared to $760,932 for the same period in 1999.  This increase was
primarily due to increases in lease operating expense and depletion,
depreciation and amortization costs.  Lease operating expenses were higher at
$2,740,656 for the three-month period ended September 30, 2000 compared to
$560,326 for the same period in 1999.  This was due to increases in expenses
associated with properties acquired in the May 2, 2000 transaction described
earlier.  Depletion, depreciation and amortization of oil and gas properties
amounted to $1,270,447 for the quarter ended September 30, 2000 compared to
$129,174 for the same period in 1999 due to a higher depletable base and
production from properties acquired in the May 2, 2000 transaction described
earlier.

As a result of the May 2, 2000 transactions, income from operations of $827,885
was realized for the quarter ended September 30, 2000 compared to a income from
operations of $196,143 for the same period in 1999.

Impairment write-down and loss on sale of marketable securities decreased to $0
for the quarter ended September 30, 2000 compared to $1,902,076 for the quarter
ended September 30, 1999.  This was a result of a significant amount of shares
sold during the 1999 period at losses and a writedown resulting from a decline
in market value considered other than temporary.

Interest expense increased from $0 for the quarter ended September 30, 1999, to
$1,295,224 for the quarter ended September 30, 2000 as a result of the debt from
the May 2, 2000 transactions.

Preferred stock dividends were $2,225,378 for the quarter ended September 30,
2000.  These dividends are associated with the preferred series of stock issued
in connection with the May 2, 2000 transactions described earlier.

In summary, due to the above factors, the net loss for the common stockholders
for the quarter ended September 30, 2000 increased to $2,753,393 ($0.05 per
share) compared to a net loss of $1,705,448 ($0.03 per share) for the same
period in 1999.

    Nine Months Ended September 30, 2000 compared to the Nine Months Ended
    ----------------------------------------------------------------------
                              September 30, 1999
                              ------------------

     Total revenue from the Company's operations for the nine months ended
September 30, 2000, was $11,241,130 compared to $2,335,317 for the nine months
ended September 30, 1999.  Revenue increased significantly over the comparable
period a year earlier due principally to higher oil and gas prices and
production from oil and gas properties acquired in the May 2, 2000 transactions.

Total operating expenses increased to $9,168,568 for the nine months ended
September 30, 2000, compared to $2,360,385 for the same period in 1999.  This
increase was primarily due to the increases in lease operating expense, and
depletion, depreciation and amortization costs.  Lease operating expenses
increased to $5,148,040 in the 2000 period compared to $1,607,135 for the nine-
month period ended September 30, 1999.  This was due to increases in expenses
associated with the properties acquired in the May 2, 2000 transaction described
earlier.  Depletion, depreciation and amortization of oil and gas properties
amounted to $2,515,239 for the nine-month period ended September 30, 2000,
compared to $475,964 for the nine-month period ended September 30, 1999, due to
a higher depletable base and production from properties acquired in the May 2,
2000 transaction described earlier.  As a result of the preceding, the income
from operations of $2,072,562 for the nine-month period ended September 30,
2000, reflects an increase over the loss from operations of $25,068 for the
nine-month period ended September 30, 1999.

Impairment write-down and loss on sale of marketable securities decreased to
$262,689 for the nine months ended September 30, 2000 compared to $6,060,891 for
the nine months ended September 30, 1999. This was a result of a significant
amount of shares sold during the 1999 period at losses and a writedown resulting
from a decline in market value considered other than temporary.

Interest expense increased from $0 for the nine months ended September 30, 1999
to $2,076,041 for the quarter ended September 30, 2000 as a result of debt from
the May 2, 2000 transactions.

Preferred stock dividends were $3,708,964 for the nine months ended September
30, 2000. These dividends are associated with the preferred series of stock
issued in connection with the May 2, 2000 transactions described earlier.

In summary, due to the above factors, the net loss for the common stockholders
for the nine months ended September 30, 2000 decreased to $4,042,634 ($0.08 per
share) compared to a net loss of $10,336,826 ($0.19 per share) which included
$4,251,961 equity in net losses of old AROC.

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

Net Cash Used in Operating Activities - AROC's net cash used in operating
activities during the first nine months of 2000 totaled $2,502,264, primarily
due to payment of a portion of the old AROC liabilities assumed in the May 2,
2000 reverse acquisition described earlier.

     Credit Facility - On May 2, 2000, old AROC entered into a purchase
agreement providing for the sale to EnCap 1996 LP, ECIC and El Paso (together
EnCap) 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,
old AROC also issued to EnCap warrants to purchase a total of 39,451,233 shares
of AROC's common stock at a price of $0.01 per share at any time until April 30,
2007 pursuant to such purchase agreement.

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), AROC obtained a new $35,000,000 credit
facility.  The credit facility provides for a revolving line of credit for three
years.  Borrowings ($25,000,000 initial borrowing) 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 AROC'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 new facility was used along with the subordinated notes, purchased by EnCap,
to retire the previous credit facility with Bank of America and to support
AROC's capital expenditure requirements.

Liquidity - AROC believes that cash on hand, net cash generated from operations,
and unused borrowing capacity under its credit facility will be adequate to
satisfy the Company's financial obligations and to meet future liquidity needs
for at least the next two fiscal years.  As of September 30, 2000, AROC's
available borrowing capacity under its credit facility was $4.5 million.

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

                                       16
<PAGE>

The timing of the Company's U.K. capital expenditures is determined annually by
a budget prepared by Burlington Resources and approved by the Company. Any
commitments will be met by funds available under the Company's credit facility
and internally generated cash flow. The level of the Company's capital
expenditures will vary in future periods depending on energy market conditions
and other related economic factors. (This is a forward-looking statement; refer
to the Cautionary Statement Regarding Forward Looking Statements).

Inflation and Prices.   In recent years, inflation has not had a significant
--------------------
impact on the operations or financial condition of the Company.

     The Company engages in oil and gas hedging activities and intends to
consider various hedging arrangements to realize commodity prices which it
considers favorable. Currently, oil hedges (costless collars) for the last
quarter of 2000 cover 66 MBbls at an average NYMEX reference price of $19.00/bbl
for the floor and $28.14/bbl for the collar. Currently, gas hedges (costless
collars) for the last quarter of 2000 and continuing until October 2001 cover
1,300 MMcf at an average NYMEX reference price of $2.49/Mcf for the floor and
$3.85/Mcf for the collar. The following table reflects the barrels and Mcf
hedged and the corresponding weighted average NYMEX reference prices for the
hedged periods shown:

                                                       NYMEX Reference

                                                        NYMEX Reference
     Period Ending                 MMcf                  Price per Mcf
-----------------------   -----------------------   ----------------------
                             (in thousands)


October 31, 2000                   100            $2.43 Floor, $3.28 Collar
October 31, 2001                  1,200           $2.50 Floor, $3.90 Collar


Average oil and gas prices received by the Company fluctuate generally with
changes in spot market prices, which may vary significantly by region.  The
Company's U.S. average gas price for the first nine months of 2000 was 67%
higher than 1999's first nine months.  The Company's U.S. average oil price for
the first nine months of 2000 was 54% higher than 1999's first nine months.

Relatively modest changes in either oil or gas prices significantly impact the
Company's results of operations and cash flow.  However, the impact of changes
in the market prices for oil and gas on the Company's average realized prices
may be reduced from time to time based on the level of the Company's hedging
activities.

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
September 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.

At September 30, 2000 the Company has certain oil and gas price collar
derivatives. The oil collar expires December 31, 2000 and the gas collars expire
October 31, 2000 and October 31, 2001. The fair value of the gas collar that
expires October 31, 2001 was $1.3 million (unrealized loss) at September 30,
2000. The Company has not completed its analysis to determine whether the gas
collar that expires October 31, 2001 will be treated as a cash flow type hedge.
The effect of adopting Statement 133 from the gas collar that expires October
31, 2001 at September 30, 2000 would be a $1.3 million balance sheet liability
and a charge to comprehensive income. If this gas collar meets the Statement 133
hedge accounting requirements the amount recorded in accumulated other
comprehensive income upon adoption of Statement 133 will be recognized in
earnings in the same periods during which production revenues are recorded. The
Company is still in process of identifying all derivatives including embedded
derivatives, if any, to determine the impact of adopting Statement 133.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
------------------------------------------------------------------

     The Company's operations are exposed to market risks primarily as a result
of changes in commodity prices, interest rates and foreign currency exchange
rates. The Company does not use derivative financial instruments for speculative
or trading purposes.

Commodity Price Risk
--------------------

     The Company produces and sells crude oil, natural gas, condensate and
natural gas liquids. As a result, the Company's financial results can be
significantly impacted as these commodity prices fluctuate widely in response to
changing market forces. The Company engages in oil and gas hedging activities
and intends to continue to consider various hedging arrangements to realize
commodity prices which it considers favorable.

                                       18
<PAGE>

     Currently, the Company has entered into various hedging instruments
(costless collars) for a total of 66 MBbls at a weighted price of $19.00/Bbl for
a floor and $28.14/Bbl for a collar, and for a total of 1,300 MMcf at a weighted
price of $2.49/Mcf for a floor and $3.85/Mcf for a collar (NYMEX reference
prices), for the last quarter of 2000 and continuing until October 2001. The
fair value of the commodity hedge agreements is the amount at which they could
be settled, based on quoted market prices. At September 30, 2000, the Company
would have been required to pay approximately $1.7 million to terminate its oil
and gas hedging agreements then in place. The Company continues to monitor oil
and gas prices and may enter into additional oil and gas hedges in the future.

Interest Rate Risk
-------------------

     The Company's interest rate risk exposure results primarily from short-term
rates, mainly LIBOR based borrowings from its credit facility with Toronto-
Dominion.  To reduce the impact of fluctuations in interest rates the Company
maintains a portion of its total debt portfolio in fixed rate debt.  At
September 30, 2000, the amount of the Company's fixed rate debt was
approximately 43% of total debt.  The Company may consider financial instruments
such as interest rate swaps to manage the impact of changes in interest rates
based on management's assessment of future interest rates, volatility of the
yield curve and the Company's ability to access the capital markets in a timely
manner.

Foreign Currency and Operations Risk
-------------------------------------

     International investments represent a significant portion of the Company's
total assets.  The Company has international operations in the United Kingdom.
As a result of the significant foreign operation, the Company's financial
results could be affected by factors such as changes in foreign currency
exchange rates, weak economic conditions or changes in the political climate in
the United Kingdom.  The Company believes the United Kingdom offers a relatively
stable political environment and does not anticipate any significant changes in
the near future.  To date, the currency risk associated with its foreign
operations has not had a material impact on the Company's financial position or
results of operations.  In the past, the Company has entered into a financial
instrument to address this risk; however, there are no current instruments in
place.  It may consider these instruments again to manage the impact of changes
in exchange rates based on management's assessment of future exchange rate
volatility.  Economic conditions in the United Kingdom are currently in a
favorable position for continued investment and management believes this will
continue without any significant change in the near future.
