                         PATINA OIL & GAS CORPORATION

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1)  ORGANIZATION AND NATURE OF BUSINESS

   Patina Oil & Gas Corporation (the "Company" or "Patina"), a Delaware
corporation, was formed in 1996 to hold the assets of Snyder Oil Corporation
("SOCO") in the Wattenberg Field and to facilitate the acquisition of Gerrity
Oil & Gas Corporation ("Gerrity"). In conjunction with the Gerrity acquisition,
SOCO received 14.0 million common shares of Patina. In 1997, a series of
transactions eliminated SOCO's ownership in the Company.

   The Company's operations currently consist of the acquisition, development,
exploitation and production of oil and natural gas properties in the Wattenberg
Field of Colorado's D-J Basin.

(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   The Company utilizes the successful efforts method of accounting for its oil
and natural gas properties. Consequently, leasehold costs are capitalized when
incurred.  Unproved properties are assessed periodically within specific
geographic areas and impairments in value are charged to expense. Exploratory
expenses, including geological and geophysical expenses and delay rentals, are
charged to expense as incurred. Exploratory drilling costs are initially
capitalized, but charged to expense if and when the well is determined to be
unsuccessful.  Costs of productive wells, unsuccessful developmental wells and
productive leases are capitalized and amortized on a unit-of-production basis
over the life of the remaining proved or proved developed reserves, as
applicable.  Oil is converted to natural gas equivalents (Mcfe) at the rate of
one barrel to six Mcf.  Amortization of capitalized costs has generally been
provided over the entire Wattenberg Field, as the wells are located in the same
reservoirs.  No accrual has been provided for estimated future abandonment costs
as management estimates that salvage value will approximate or exceed such
costs.

   In 1995, the Company adopted Statement of Financial Accounting Standards No.
121 ("SFAS 121"), "Accounting for the Impairment of Long-Lived Assets."  SFAS
121 requires the Company to assess the need for an impairment of capitalized
costs of oil and gas properties on a field-by-field basis.  During 1997, the
Company recorded an impairment of $26.0 million to oil and gas properties as the
estimated future cash flows (undiscounted and without interest charges) expected
to result from these assets and their disposition, largely proven undeveloped
drilling locations, was less than their net book value.  The impairment
primarily resulted from low year-end oil and natural gas prices.  While no
impairments have been necessary since 1997, changes in underlying assumptions or
the amortization units could result in impairments in the future.

Gas facilities and other

   Depreciation of gas gathering and transportation facilities is provided using
the straight-line method over an estimated useful life of five years.  Equipment
is depreciated using the straight-line method with estimated useful lives
ranging from three to five years.

Other Assets

   Other Assets at December 31, 1999 were comprised of $988,000 of notes
receivable from certain officers and key managers of the Company.  See Note (9).
At June 30, 2000, the notes receivable balance of $690,000 was classified as a
current asset and included in Inventory and other as these notes are due within
one year.  At December 31, 1999, the balance also included net loan origination
fees of $303,000. The remaining net loan origination of fees $151,000 at June
30, 2000 were classified as a current asset and are included in Inventory and
other, as they will be fully amortized by December 31, 2000.

Section 29 Tax Credits

   The Company has entered into arrangements to monetize its Section 29 tax
credits.  These arrangements result in revenue increases of approximately $0.40
per Mcf on production volumes from qualified Section 29 properties.  As a
result, additional gas revenues of $1.2 million and $1.8 million were recognized
for the six months ended June 30, 1999 and 2000, respectively.  These
arrangements are expected to increase revenues through December 31, 2002, at
which point the tax credits expire.

Gas Imbalances

   The Company uses the sales method to account for gas imbalances.  Under this
method, revenue is recognized based on the cash received rather than the
Company's proportionate share of gas produced.  Gas imbalances at December 31,
1999 and June 30, 2000 were insignificant.

Financial Instruments

   The book value and estimated fair value of cash and equivalents was $626,000
and $483,000 at December 31, 1999 and June 30, 2000.  The book value and
estimated fair value of the senior debt was $132.0 million and $121.0 million at
December 31, 1999 and June 30, 2000.  The book value of these assets and
liabilities approximates fair value due to the short maturity or floating rate
structure of these instruments.

   From time to time, the Company enters into commodity derivative contracts and
fixed-price physical contracts to manage its exposure to oil and gas price
volatility.  Commodity derivatives contracts, which are generally placed with
major financial institutions or with counterparties of high credit quality that
the Company believes are minimal credit risks, may take the form of futures
contracts, swaps or options.  The oil and gas reference prices of these
commodity derivatives contracts are based upon oil and natural gas futures which
have a high degree of historical correlation with actual prices received by the
Company.  The Company accounts for its commodity derivatives contracts using the
hedge (deferral) method of accounting.  Under this method, realized gains and
losses on such contracts are deferred and recognized as an adjustment to oil and
gas sales revenues in the period in which the physical product to which the
contracts relate, is actually sold.  Gains and losses on commodity derivatives
contracts that are closed before the hedged production occurs are deferred until
the production month originally hedged.

   The Company entered into various swap contracts for oil (NYMEX based) for the
first six months of 1999 and 2000 and recognized losses of $370,000 and $4.7
million related to these swap contracts.

   The Company entered into various CIG and PEPL index based swap contracts for
natural gas for the first six months of 1999 and 2000. The Company recognized
gains of $310,000 in the six month period ended June 30, 1999 and a loss of $2.4
million in the six month period ended June 30, 2000 related to these swap
contracts.

   As of June 30, 2000, the Company had entered into swap contracts for oil
(NYMEX based) for approximately 3,375 barrels of oil per day for the remainder
of 2000 at fixed prices ranging from $20.00 to $25.75 per barrel and 1,560
barrels of oil per day for 2001 at fixed prices ranging from $23.05 to $26.60
per barrel. Certain swap contracts for oil (NYMEX based) contain "knock-out"
provisions. If the average price of NYMEX WTI crude oil falls below the "knock-
out" price for the contract month, the swaps will be considered "knocked-out"
and no payment will be made to the Company for the applicable month.  These
swaps are summarized in the table below.  The overall weighted average hedged
price for the swap contracts is $22.14 per barrel for the remainder of 2000 and
$23.76 per barrel for 2001 (NYMEX based). The unrecognized losses on these
contracts totaled $6.9 million and $4.8 million based on estimated market values
at June 30, 2000 and July 25, 2000, respectively.

   As of June 30, 2000, the Company had entered into natural gas swap contracts
for approximately 32,500 MMBtu's per day for the remainder of 2000 at fixed
prices ranging from $2.06 to $3.68 per MMBtu and 18,700 MMBtu's per day for the
first six months of 2001 at fixed prices ranging from $2.55 to $3.71 per MMBtu
on CIG index based swap contracts. The Company also has entered into physical
natural gas sale contracts for the delivery of approximately 10,900

                                       8
<PAGE>

MMBtu's per day for the remainder of 2000 at prices ranging from $2.29 to $3.04
per MMBtu and 1,200 MMBtu's per day for the first six months of 2001 at prices
ranging from $2.67 to $3.08 per MMBtu. The weighted average daily volumes and
prices for these natural gas swaps and physical contracts are 43,400 MMBtu's per
day at $2.48 per MMBtu for the remainder of 2000 and 19,900 MMBtu's per day at
$3.01 per MMBtu for the first six months of 2001. The unrecognized losses on the
swap contracts totaled $10.8 million and $5.7 million based on estimated market
values at June 30, 2000 and July 25, 2000, respectively.

   As of July 25, 2000, the Company was a party to the following fixed price
swap and physical arrangements summarized by quarter:

   In October 1998, the Company entered into an interest rate swap contract for
a two-year period, extendable for one additional year at the option of the third
party.  The contract is for $30.0 million principal with a fixed interest rate
of 4.57% payable by the Company and the variable interest rate, the three-month
LIBOR, payable by the third party. The difference between the Company's fixed
rate of 4.57% and the three-month LIBOR rate, which is reset every 90 days, is
received or paid by the Company in arrears every 90 days. The Company received
$184,000 in 1999 pursuant to this contract and $234,000 in the first six months
of 2000. The unrecognized gain on this contract totaled $296,000 based on
estimated market values at June 30, 2000.

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 ("SFAS 133"), "Accounting for Derivative
Instruments and Hedging Activities."  SFAS 133 establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded on the
balance sheet as either an asset or liability measured at its fair value.  It
also requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. Special
accounting for qualifying hedges allows a derivative's gains and losses to
offset related results on the hedged item in the income statement, and requires
that a company must formally document, designate, and assess the effectiveness
of transactions that receive hedge accounting.  SFAS 133 is effective for fiscal
years beginning after June 15, 2000.  The Company has not yet quantified the
impacts of adopting SFAS 133 on its financial statements and has not determined
the timing of, or method of, adoption of SFAS 133.  However, SFAS 133 will
likely increase volatility in earnings and other comprehensive income.

Stock Options and Awards

   The Company accounts for its stock-based compensation plans under the
principles prescribed by the Accounting Principles Board's Opinion No. 25 ("APB
No. 25"), "Accounting for Stock Issued to Employees."  Accordingly, stock
options awarded under the Employee Plan and the Non-Employee Directors Plan are
considered to be "noncompensatory" and do not result in recognition of
compensation expense.  However, the restricted stock awarded under the
Restricted Stock Plan is considered to be "compensatory" and the Company
recognized $479,000 and $140,000 of non-cash general and administrative expenses
for the six months ended June 30, 1999 and 2000, respectively.  These costs will
be fully amortized by December 31, 2000.  See Note (6).

Per Share Data

   The Company uses the weighted average number of shares outstanding in
calculating earnings per share data. When dilutive, options and warrants are
included as share equivalents using the treasury stock method and are included
in the calculation of diluted per share data.  Common stock issuable upon
conversion of convertible preferred securities is also included in the
calculation of diluted per share data if their effect is dilutive.

Risks and Uncertainties

   Historically, the market for oil and natural gas has experienced significant
price fluctuations.  Prices for oil and natural gas in the Rocky Mountain region
have been particularly volatile in recent years.  The price fluctuations can
result from variations in weather, levels of regional or national production,
availability of transportation capacity to other regions of the country and
various other factors.  Increases or decreases in prices received could have a
significant impact on future results.

Other

   All liquid investments with an original maturity of three months or less are
considered to be cash equivalents. Certain amounts in prior period consolidated
financial statements have been reclassified to conform with the current
classifications. The consolidated financial statements include the accounts of
the Company and its wholly owned subsidiaries.

   All significant intercompany balances and transactions have been eliminated
in consolidation.  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

   In the opinion of management, those adjustments to the financial statements
(all of which are of a normal and recurring nature) necessary to present fairly
the financial position and results of operations have been made. These interim
financial statements should be read in conjunction with the Company's Annual
Report on Form 10-K for the year ended December 31, 1999.

(3)  OIL AND GAS PROPERTIES

   The cost of oil and gas properties at December 31, 1999 and June 30, 2000
included approximately $225,000 and $113,000 in net unevaluated leasehold costs
related to a prospect in Wyoming.  Acreage is generally held for exploration,
development or resale and its value, if any, is excluded from amortization.  The
following table sets forth costs incurred related to oil and gas properties:

   The following indebtedness was outstanding on the respective dates:

   In July 1999, in conjunction with the redemption of the 11.75% Senior
Subordinated Notes, the Company entered into a Second Amended and Restated Bank
Credit Agreement (the "Credit Agreement"). The Credit Agreement is a revolving
credit facility in an aggregate amount up to $200.0 million. The amount
available under the facility is adjusted semi-annually, each May 1 and November
1, and equaled $175.0 million at June 30, 2000.

   The Company may elect that all or a portion of the credit facility bear
interest at a rate equal to: (i) the higher of (a) the prime rate or (b) the
Federal Funds Effective Rate plus .5%, or (ii) the rate at which Eurodollar
deposits for one, two, three or six months  (as selected by the Company) are
offered in the interbank Eurodollar market plus a margin which fluctuates from
1.00% to 1.50%, determined by a debt to EBITDA ratio.  The average interest rate
under the facility approximated 7.5% during the first six months of 2000 and was
7.9% at June 30, 2000.

   In October 1998, the Company entered into an interest rate swap contract for
a two-year period, extendable for one additional year at the option of the third
party.  The contract is for $30.0 million principal with a fixed interest rate
of 4.57% payable by the Company and the variable interest rate, the three-month
LIBOR, payable by the third party. The difference between the Company's fixed
rate of 4.57% and the three-month LIBOR rate, which is reset every 90 days, is
received or paid by the Company in arrears every 90 days. The Company received
$184,000 in 1999 pursuant to this contract and $234,000 in the first six months
of 2000.

                                       11
<PAGE>

     The Credit Agreement contains certain financial covenants, including but
not limited to a maximum total debt to EBITDA ratio and a minimum current ratio.
The Credit Agreement also contains certain negative covenants, including but not
limited to restrictions on indebtedness; certain liens; guaranties, speculative
derivatives and other similar obligations; asset dispositions; dividends, loans
and advances; creation of subsidiaries; investments; leases; acquisitions;
mergers; changes in fiscal year; transactions with affiliates; changes in
business conducted; sale and leaseback and operating lease transactions; sale of
receivables; prepayment of other indebtedness; amendments to principal
documents; negative pledge causes; issuance of securities; and non-speculative
commodity hedging. Borrowings under the Credit Agreement mature in July 2003,
but may be prepaid at anytime. The Company has periodically negotiated
extensions of the Credit Agreement; however, there is no assurance the Company
will be able to do so in the future. The Company had a restricted payment
basket, as defined in the Credit Agreement, of $11.7 million as of June 30,
2000, which may be used to repurchase common stock, preferred stock and warrants
and pay dividends on its common stock. In July 2000, the Company amended the
Credit Agreement and created an additional restricted payment basket to allow
for the repurchase of up to $25.0 million of 8.50% preferred stock or the common
stock issued upon conversion of the 8.50% preferred stock. This additional
repurchase basket expires on December 31, 2000.

     Scheduled maturities of indebtedness for the next five years are zero for
2001, 2002, and $121.0 million in 2003. Management intends to review the
facility and extend the maturity on a regular basis; however, there can be no
assurance that the Company will be able to do so. Cash payments for interest
totaled $6.1 million and $4.9 million the first six months ended June 30, 1999
and 2000, respectively.


(5)  STOCKHOLDERS' EQUITY

     A total of 100,000,000 common shares, $0.01 par value, are authorized of
which 16,950,748 were issued and outstanding at June 30, 2000. The common stock
is listed on the New York Stock Exchange. Prior to December 1997, no dividends
had been paid on common stock. A quarterly cash dividend of $0.01 per common
share was initiated in December 1997. The dividend was increased to $0.02 per
common share in the fourth quarter of 1999. The following is a schedule of the
changes in the Company's outstanding common stock for the following periods:

     At June 30, 2000, the Company had 2,919,353 common stock warrants
outstanding. These warrants are exercisable at $12.50 for one share of common
stock and expire in May 2001. The warrants are listed on the New York Stock
Exchange.

     A total of 5,000,000 preferred shares, $0.01 par value, are authorized. At
June 30, 2000, the Company had 1,618,511 shares of 8.50% preferred stock ("8.50%
Preferred") outstanding with an aggregate liquidation preference of $40.5
million. Each share of the 8.50% Preferred is convertible into common stock at
any time at $9.50 per share or 2.6316 common shares. The 8.50% Preferred pays
quarterly cash dividends, when and if declared by the Board of

                                       12
<PAGE>

Directors. The 8.50% Preferred is redeemable at the option of the Company at any
time after October 1, 2000 at 106% of its stated value declining by 2% per annum
thereafter. The Company expects to call the 8.50% Preferred for redemption as of
October 1, 2000. The liquidation preference is $25.00 per share, plus accrued
and unpaid dividends. The 8.50% Preferred is privately held. Holders of the
8.50% Preferred are generally entitled to vote with the common stock, based upon
the number of shares of common stock into which the shares of 8.50% Preferred
are convertible. The Company paid $1.8 million and $1.9 million in dividends
during the six months ended June 30, 1999 and 2000, respectively. Dividends
through October 1999 were paid in kind. As such, the Company issued 72,960 of
additional 8.50% preferred shares as dividends during the first six months of
1999. Dividends subsequent to October 1999 have been paid in cash.

     In December 1999, the Company called for redemption all remaining 7.125%
preferred stock. The effective date of the redemption was January 21, 2000. Of
the 564,800 preferred shares called, 51,000 were converted into 148,000 shares
of common stock and the remaining 513,800 were redeemed for $13.4 million in
cash. The cash redemption was financed with borrowings under the bank credit
facility. The Company paid $1.2 million and $600,000 in preferred dividends
during the six months ended June 30, 1999 and 2000, respectively. Included in
the first quarter 2000 payment was $549,000 of redemption premium paid to
shareholders that elected to redeem their preferred stock for cash.

     The Company adopted Statement of Financial Accounting Standards No. 128
("SFAS 128"), "Earnings per Share" during 1997. SFAS 128 specifies computation,
presentation and disclosure requirements for earnings per share for entities
with publicly held common stock or potential common stock. The following tables
sets forth the computation of basic and diluted earnings per share:

(6)  EMPLOYEE BENEFIT PLANS

401(k) Savings

     The Company has a 401(k) profit sharing and savings plan (the "401(k)
Plan"). Eligible employees may make voluntary contributions to the 401(k) Plan.
Employee contributions are limited as specified in the 401(k) Plan. The Company
may, at its discretion, make matching or profit sharing contributions to the
401(k) Plan. The Company has historically made profit sharing contributions to
the 401(k) Plan, which totaled $483,000 for 1999. The 1999 profit sharing
contribution was made through the issuance of 61,300 shares of the Company's
common stock.

Stock Purchase Plan

     In 1998, the Company adopted and the stockholders approved a stock purchase
plan ("Stock Purchase Plan"). Pursuant to the Stock Purchase Plan, officers,
directors and certain managers are eligible to purchase shares of common stock
at prices ranging from 50% to 85% of the closing price of the stock on the
trading day prior to the date of purchase ("Closing Price"). In addition,
employee participants may be granted the right to purchase shares pursuant to
the Stock Purchase Plan with all or a part of their salary and bonus. A total of
500,000 shares of common stock are reserved for possible purchase under the
Stock Purchase Plan. In May 1999, an amendment to the Stock Purchase Plan was
approved by the stockholders allowing for the annual renewal of the 500,000
shares of common stock reserved for possible purchase under the Plan. In 1999,
the Board of Directors approved 136,300 common shares (exclusive of shares
available for purchase with participants' salaries and bonuses) for possible
purchase by participants at 75% of the Closing Price during the current Plan
Year as defined in the Stock Purchase Plan. During the twelve months ended
December 31, 1999, participants had purchased 92,900 shares of common stock at
prices ranging from $5.06 to $8.63 per share ($3.80 to $6.47 net price per
share), resulting in cash proceeds to the Company of $395,000. The Company
recorded non-cash general and administrative expenses of $53,000 associated with
these purchases in 1999. During the six months ended, June 30, 2000,
participants had purchased 85,800 of common stock with participant's 1999
bonuses at $9.19 per share ($6.89 net price per share) and 52,400 shares of
common stock at prices ranging from $16.50 to $17.31 per share ($12.38 to $12.98
net price per share), resulting in cash proceeds to the Company of $665,000. The
Company recorded non-cash general and administrative expenses of $89,000
associated with these purchases in 2000.

Stock Option and Award Plans

     In 1996, the shareholders adopted a stock option plan for employees
("Employee Plan") providing for the issuance of options at prices not less than
fair market value. Options to acquire the greater of up to three million shares
of common stock or 10% of outstanding diluted common shares may be outstanding
at any given time. The specific terms of grant and exercise are determinable by
a committee of independent members of the Board of Directors. A summary by year
of stock options granted under the Employee Plan is summarized below:

                                                        Weighted
                                          Range         Average

          ----               -------  --------------  ------------
          1996.............  512,000  $         7.75         $7.75
          1997.............  521,000  $8.75 - $ 9.88         $9.75

          1999.............  630,000  $2.94 - $ 9.13         $3.54
          2000.............  503,000  $9.19 - $20.75         $9.28

The options generally vest over a three-year period (30%, 60%, 100%) and expire
five years from the date of grant, except for 250,000 five-year options which
were fully vested at the date of grant in October 1997 at an exercise price of
$9.88.

     In 1996, the shareholders adopted a stock grant and option plan (the
"Directors' Plan") for non-employee Directors. The Directors' Plan provides for
each non-employee Director to receive common shares having a market value equal
to $2,500 quarterly in payment of one-half their retainer.  A total of 8,600
shares were issued in 1999 and 1,900 were issued in the first half of 2000.  It
also provides for 5,000 options to be granted annually to each non-employee
Director.  A summary by year of stock options granted under the Directors' Plan
is summarized below:

                                                        Weighted

          1998.............   35,000  $7.19 - $ 7.75        $ 7.59
          1999.............   30,000  $2.94 - $ 5.13        $ 4.76
          2000.............   25,000  $        17.44        $17.44

     The options generally vest over a three-year period (30%, 60%, 100%) and
expire five years from the date of grant.

     In 1997, the shareholders approved a special stock grant and purchase plan
for certain officers and managers ("Management Investors"). The plan provided
for the grant of certain restricted common shares to the Management Investors.
These shares vest at 25% per year on January 1, 1998, 1999, 2000 and 2001. The
non-vested granted common shares have been recorded as Deferred Compensation in
the equity section of the accompanying consolidated balance sheets. The
Management Investors simultaneously purchased additional common shares from the
Company at $9.875 per share. A portion of the purchase was financed by the
Company. See Note (9).

     In conjunction with the appointment of a President in March 1998, the
President was included in the stock grant and purchase plans. He was granted
100,000 restricted common shares that vest at 33% per year in March 1999, 2000
and 2001. The non-vested granted common shares have been recorded as Deferred
Compensation in the equity section of the accompanying consolidated balance
sheets. The President simultaneously purchased 100,000 common shares from the
Company at $6.875 per share. A portion of this purchase ($584,000) was also
financed by the Company. See Note (9).

     In April 1999, the Chief Executive Officer was granted 100,000 restricted
shares of common stock and was simultaneously granted options to purchase
300,000 common shares in consideration of his voluntary reduction in cash
salary, waiver of any 1998 bonus and other compensation arrangements. The shares
vested ratably throughout 1999.

     The Company recognized $479,000 and $140,000 of non-cash general and
administrative expenses for the six months ended June 30, 1999 and 2000, with
respect to the stock grants. These costs will be fully amortized by December 31,
2000.


(7)  FEDERAL INCOME TAXES

     A reconciliation of the federal statutory rate to the Company's effective
rate as they apply to the provision for the six months ended June 30, 1999 and
2000 follows:

                                                       1999    2000

                                                       ====    ====

     For tax purposes, the Company had regular net operating loss carryforwards
of approximately $88.4 million and alternative minimum tax ("AMT") loss
carryforwards of approximately $42.0 million at December 31, 1999. Utilization
of the regular and AMT net operating loss carryforwards will be limited to
approximately $12.5 million per year as a result of the redistribution of SOCO's
majority ownership in the Company in October 1997. In addition, utilization of
$31.9 million regular net operating loss carryforwards and $31.6 million AMT
loss carryforwards will be limited to $5.2 million per year as a result of the
Gerrity acquisition in 1996. These carryforwards expire from 2006 through 2018.
At December 31, 1999, the Company had alternative minimum tax credit
carryforwards of $650,000 that are available indefinitely.


(8)  MAJOR CUSTOMERS

     During the six months ended June 30, 1999 and 2000, Duke Energy Field
Services, Inc. accounted for 38% and 32%, BP Amoco Production Company accounted
for 19% and 23% and Aurora Natural Gas, LLC accounted for 14% and 4% of
revenues, respectively. Management believes that the loss of any individual
purchaser would not have a long-term material adverse impact on the financial
position or results of operations of the Company.

(9)  RELATED PARTY

     In October 1997, certain officers and managers purchased common shares at
$9.875 per share from the Company. A portion of this original purchase was
financed by the Company through the issuance of 8.50% recourse promissory notes.
The remaining notes balance at June 30, 2000 of $106,000 are secured by the
common stock purchased and additional common shares granted to the respective
officers and managers. Interest is due annually and the notes mature in January
2001. These notes have been reflected as current assets and are included in
Inventory and other in the accompanying consolidated balance sheets.

     In conjunction with the appointment of the new President in March 1998, the
President purchased 100,000 shares of common stock at $6.875 per share. The
Company loaned him $584,000, or 85% of the purchase price, represented by a
recourse promissory note that bears interest at 8.50% per annum payable each
March 31 until the note is paid. The note matures in March 2001 and is secured
by all of the shares purchased and granted to him (100,000 shares) in connection
with his employment with the Company. In consideration of the depressed stock
price and overall lower year-end bonuses, the interest due as of March 31, 1999
under the Management Investor's and President's notes was forgiven by the
Company in April 1999. Interest on the notes due March 31, 2000 was paid in
full. This note has been reflected as a current asset and included in Inventory
and other in the accompanying consolidated balance sheets

(10) COMMITMENTS AND CONTINGENCIES

     The Company leases office space and certain equipment under non-cancelable
operating leases. Future minimum lease payments under such leases approximate
$500,000 per year from 2000 through 2001. The office lease expires in November
2001. The Company is a party to various other lawsuits incidental to its
business, none of which are anticipated to have a material adverse impact on its
financial position or results of operations.

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

Results of Operations

Three months ended June 30, 2000 compared to three months ended June 30, 1999.

     Revenues for the second quarter of 2000 totaled $31.9 million, a 56%
increase from the prior year period. The increase was due primarily to a rise in
production and higher oil and gas prices. Net income for the second quarter of
2000 totaled $10.6 million compared to net income of $1.7 million in the second
quarter of 1999. The increase was attributable to higher production and the
sharp increase in oil and gas prices.

     Average daily production for the second quarter totaled 4,249 barrels of
oil and 87.6 MMcf of gas (113.1 MMcfe), an increase of 8% on an equivalent basis
from the same period in 1999. During the quarter, eight wells were drilled or
deepened and 43 refracs and four recompletions were performed, compared to 10
new wells or deepenings and 23 refracs and recompletions in 1999. Based on a
current capital budget of $38.0 million capital budget for 2000, the Company
expects production to continue to increase in the remainder of the year. The
level of development activity is heavily dependent on oil and gas prices.

     Average oil prices increased 44% from $15.17 per barrel in the second
quarter of 1999 to $21.92 in 2000. Average natural gas prices increased 47% from
$1.97 per Mcf for the second quarter of 1999 to $2.90 in 2000. The average oil
price includes hedging losses of $370,000 or $0.93 per barrel and $2.3 million
or $5.83 per barrel in the second quarters of 1999 and 2000, respectively. The
average natural gas prices include hedging losses of $180,000 or $0.03 per Mcf
and $2.7 million or $0.34 per Mcf for the second quarters of 1999 and 2000,
respectively. Direct operating expenses, consisting of lease operating and
production taxes, totaled $4.9 million or $0.48 per Mcfe for the second quarter
of 2000 compared to $4.5 million or $0.47 per Mcfe in the prior year period. The
increase in direct operating expenses for the quarter was attributed to a
$578,000 rise in production taxes as a result of higher average oil and gas
prices and production.

     General and administrative expenses, net of third party reimbursements, for
the second quarter of 2000 totaled $1.8 million, a $289,000 or 20% increase from
the same period in 1999. The increase in expense is primarily due to the Company
receiving lower reimbursements from third party working interest owners that are
offset against general and administrative expenses. The lower operating fees are
a result of the Company increasing its working interest ownership in its oil and
gas properties as a result of a property exchange with HS Resources and other
minor interest acquisitions in late 1999. Included in general and administrative
expenses is $305,000 and $70,000 for the three months ended June 30, 1999 and
2000 of non-cash expenses related to the common stock grants awarded to officers
and managers in 1997. These non-cash expenses will be fully amortized by
December 31, 2000.

     Interest and other expenses fell to $2.4 million in the second quarter of
2000, a decrease of $570,000 or 19% from the prior year period. Interest expense
decreased as a result of lower average debt balances and lower interest rates on
the Company's debt due to the redemption of the 11.75% Subordinated Notes in
July 1999. The redemption was financed with borrowings under the bank credit
facility. The Company's average interest rate for the second quarter of 2000 was
7.6% compared to 9.1% in 1999.

     Depletion, depreciation and amortization expense for the second quarter of
2000 totaled $9.5 million, a decrease of $285,000 from the prior year period.
Depletion expense totaled $9.3 million or $0.90 per Mcfe for the second quarter
of 2000 compared to $9.6 million or $1.01 per Mcfe for 1999. Although there was
an 8% increase in oil and gas production over the second quarter of 1999, total
depletion expense declined due to a decrease in the depletion rate. The
depletion rate was lowered in the fourth quarter of 1999 and in the second
quarter of 2000 in conjunction with the completion of the year-end 1999 and mid-
year 2000 reserve reports. The reduction reflects additional oil and gas
reserves due primarily to the identification of additional refrac projects and
drilling locations, upward revisions due to over-performance and the increase in
oil and gas prices. Depreciation and amortization expense for the quarter
totaled $269,000 or $0.03 per Mcfe compared to $240,000 or $0.03 per Mcfe in
1999.

Six months ended June 30, 2000 compared to six months ended June 30, 1999.

     Revenues for the six months ended June 30, 2000 totaled $63.4 million, a
71% increase from the prior year period. The increase was due primarily to
increases in production and higher oil and gas prices. Net income for the six
month period totaled $19.8 million compared to a net loss of $276,000 in 1999.
The increase was attributable to higher production and the sharp increase in oil
and gas prices.

     Average daily production for the first six months of 2000 totaled 4,428
barrels of oil and 88.5 MMcf of gas (115.1 MMcfe), an increase of 12% on an
equivalent basis from the same period in 1999. During the period, 26 wells were
drilled or deepened and 77 refracs and five recompletions were performed,
compared to 21 new wells or deepenings and 50 refracs and recompletions in 1999.
Based on a current capital budget of $38.0 million for 2000, the Company expects
production to continue to increase in the remainder of the year. The level of
development activity is heavily dependent on oil and gas prices.

     Average oil prices increased 63% from $13.36 per barrel in the first six
months of 1999 to $21.72 in 2000. Average natural gas prices increased 52% from
$1.85 per Mcf for the first six months of 1999 to $2.81 in 2000. The average oil
price includes hedging losses of $370,000 or $0.45 per barrel and $4.7 million
or $5.80 per barrel in the first six months of 1999 and 2000, respectively. The
average natural gas prices include a hedging gain of $310,000 or $0.02 per Mcf
in 1999 and hedging losses of $2.4 million or $0.15 per Mcf for the six months
ended June 30, 2000. Direct operating expenses, consisting of lease operating
and production taxes, totaled $10.5 million or $0.50 per Mcfe for the first six
months of 2000 compared to $8.6 million or $0.46 per Mcfe in the prior year
period. The increase in direct operating expenses in the first six months of
2000 was attributed to a $1.7 million rise in production taxes as a result of
higher average oil and gas prices and production.

     General and administrative expenses, net of third party reimbursements, for
the first six months of 2000 totaled $3.4 million, a $575,000 or 20% increase
from the same period in 1999. The increase in expense is primarily due to the
Company receiving lower reimbursements from third party working interest owners
that are offset against general and administrative expenses. The lower
reimbursements are a result of the Company increasing its working interest
ownership in its oil and gas properties as a result of a property exchange with
HS Resources and other minor interest acquisitions in late 1999. Included in
general and administrative expenses is $479,000 and $140,000 for the six months
ended June 30, 1999 and 2000 of non-cash expenses related to the common stock
grants awarded to officers and managers in 1997. These non-cash expenses will be
fully amortized by December 31, 2000.

     Interest and other expenses fell to $5.0 million in the six month period
ended June 30, 2000, a decrease of $922,000 or 16% from the prior year period.
Interest expense decreased as a result of lower average debt balances and lower
interest rates on the Company's debt due to the redemption of the 11.75%
Subordinated Notes in July 1999. The redemption was financed with borrowings
under the bank credit facility. The Company's average interest rate for the
first six months of 2000 was 7.5% compared to 9.1% in 1999.

     Depletion, depreciation and amortization expense for the first six months
of 2000 totaled $19.8 million, a decrease of $277,000 from the prior year
period. Depletion expense totaled $19.3 million or $0.92 per Mcfe for the first
six months of 2000 compared to $19.6 million or $1.05 per Mcfe for 1999.
Although there was a 12% increase in oil and gas production over 1999, total
depletion expense declined due to decreases in the depletion rate. The depletion
rate was lowered in the fourth quarter of 1999 and in the second quarter of 2000
in conjunction with the completion of the year-end 1999 and mid-year 2000
reserve reports reflecting additional oil and gas reserves. Depreciation and
amortization expense for the six month period totaled $511,000 or $0.02 per Mcfe
compared to $470,000 or $0.03 per Mcfe in 1999.

Development, Acquisition and Exploration

   During the first six months of 2000, the Company incurred $17.4 million in
capital expenditures, including $17.2 million of development expenditures.
During the period, the Company successfully drilled or deepened 26 wells,
refraced 77 wells, and recompleted five wells.  The Company anticipates
incurring approximately $38.0 million on development expenditures during 2000.
The decision to increase or decrease development activity is heavily dependent
on oil and gas prices.

Financial Condition and Capital Resources

   At June 30, 2000, the Company had $327.0 million of assets.  Total
capitalization was $291.3 million, of which 58% was represented by stockholders'
equity and 42% by bank debt.  During the first six months of 2000, net cash
provided by operations totaled $42.9 million, as compared to $15.0 million in
the same period in 1999 ($44.2 million and $19.8 million prior to changes in
working capital, respectively).  At June 30, 2000, there were no significant
commitments for capital expenditures. The Company anticipates 2000 capital
expenditures, exclusive of acquisitions, to approximate $38.0 million. The level
of these and other future expenditures is largely discretionary, and the amount
of funds devoted to any particular activity may increase or decrease
significantly, depending on available opportunities and market conditions.  The
Company plans to finance its ongoing development, acquisition and exploration
expenditures and additional equity security repurchases using internal cash
flow, proceeds from asset sales and bank borrowings. In addition, joint ventures
or future public and private offerings of debt or equity securities may be
utilized.

   In July 1999, in conjunction with the redemption of the 11.75% Senior
Subordinated Notes, the Company entered into a Second Amended and Restated Bank
Credit Agreement (the "Credit Agreement"). The Credit Agreement is a revolving
credit facility in an aggregate amount up to $200.0 million. The amount
available under the facility is adjusted semi-annually, each May 1 and November
1, and equaled $175.0 million at June 30, 2000.

   The Credit Agreement contains certain financial covenants, including but not
limited to a maximum total debt to EBITDA ratio and a minimum current ratio. The
Credit Agreement also contains certain negative covenants, including but not
limited to restrictions on indebtedness; certain liens; guaranties, speculative
derivatives and other similar obligations; asset dispositions; dividends, loans
and advances; creation of subsidiaries; investments; leases; acquisitions;
mergers; changes in fiscal year; transactions with affiliates; changes in
business conducted; sale and leaseback and operating lease transactions; sale of
receivables; prepayment of other indebtedness; amendments to principal
documents; negative pledge causes; issuance of securities; and non-speculative
commodity hedging. Borrowings under the Credit Agreement mature in July 2003,
but may be prepaid at anytime. The Company has periodically negotiated
extensions of the Credit Agreement; however, there is no assurance the Company
will be able to do so in the future.  The Company had a restricted payment
basket, as defined by the Credit Agreement, of $11.7 million as of June 30,
2000, which may be used to repurchase common stock, preferred stock and warrants
and pay dividends on its common stock. In July 2000, the Company amended the
Credit Agreement and created an additional restricted payment basket to allow
for the repurchase of up to $25.0 million of 8.50% preferred stock or the common
stock issued upon conversion of the 8.50% preferred stock.  This additional
repurchase basket expires on December 31, 2000.

   The Company may elect that all or a portion of the credit facility bear
interest at a rate equal to: (i) the higher of (a) the prime rate or (b) the
Federal Funds Effective Rate plus .5%, or  (ii) the rate at which Eurodollar
deposits for one, two, three or six months  (as selected by the Company) are
offered in the interbank Eurodollar market plus a margin which fluctuates from
1.00% to 1.50%, determined by a debt to EBITDA ratio.  The average interest rate
under the facility approximated 7.5% during the first six months of 2000 and was
7.9% at June 30, 2000.

   In October 1998, the Company entered into an interest rate swap contract for
a two-year period, extendable for one additional year at the option of the third
party.  The contract is for $30.0 million principal with a fixed interest rate
of 4.57% payable by the Company and the variable interest rate, the three-month
LIBOR, payable by the third party. The difference between the Company's fixed
rate of 4.57% and the three-month LIBOR rate, which is reset every 90 days, is
received or paid by the Company in arrears every 90 days. The Company received
$184,000 in 1999 pursuant to this contract and $234,000 in the first six months
of 2000.

                                       20

   The Company had $72.3 million of 11.75% Senior Subordinated Notes due July
15, 2004 outstanding on June 30, 1999.  The Notes had been reflected in the
financial statements at a book value of 105.875% of their principal amount, the
initial call price ($68.3 million of principal amount outstanding as of June 30,
1999).  The Notes became redeemable and were redeemed on July 15, 1999 at the
call price of 105.875%. The redemption was financed with borrowings under the
bank credit facility.

   In conjunction with the appointment of a President in March 1998, the
President purchased 100,000 shares of common stock at $6.875 per share.  The
Company loaned him $584,000, or 85% of the purchase price, represented by a
recourse promissory note that bears interest at 8.50% per annum payable each
March 31 until the note is paid. The note matures in March 2001 and is secured
by the 200,000 shares purchased and granted to him in connection with his
employment with the Company.

   The Company has entered into arrangements to monetize its Section 29 tax
credits.  These arrangements result in revenue increases of approximately $0.40
per Mcf on production volumes from qualified Section 29 properties.  As a
result, additional gas revenues of $1.2 million and $1.8 million were recognized
for the six months ended June 30, 1999 and 2000, respectively.  These
arrangements are expected to increase revenues through December 31, 2002, at
which point the tax credits expire.

   The Company's primary cash requirements will be to finance acquisitions,
development expenditures, repayment of indebtedness, and general working capital
needs.  However, future cash flows are subject to a number of variables,
including the level of production and oil and natural gas prices, and there can
be no assurance that operations and other capital resources will provide cash in
sufficient amounts to maintain planned levels of capital expenditures or that
increased capital expenditures will not be undertaken.

   The Company believes that borrowings available under its Credit Agreement,
projected operating cash flows and the cash on hand will be sufficient to cover
its working capital, capital expenditures, planned development activities and
debt service requirements for the next 12 months.  In connection with
consummating any significant acquisition, additional debt or equity financing
will be required, which may or may not be available on terms that are acceptable
to the Company.

Year 2000 Issues

   The Company is aware of the issues associated with the programming code in
many existing computer systems and devices with embedded technology.  The "Year
2000" problem concerns the inability of information and technology-based
operating systems to properly recognize and process date-sensitive information
beyond December 31, 1999. Since 1997, the Company has been upgrading its
information systems with Year 2000 compliant software and hardware. The
conversion from calendar year 1999 to calendar year 2000 occurred without any
disruption to the Company's operations or business systems. The Company will
continue to monitor any Year 2000 issues, both internally and with third party
dependencies with respect to vendors, suppliers, customers and other significant
business relationships.  Such monitoring will be on going and encompassed in
normal operations.  The total costs incurred to date in the assessment,
evaluation and remediation of the Year 2000 matters plus any additional costs
that may be incurred are expected to be less than management's original estimate
of $100,000.

Market and Commodity Risk

   The Company's major market risk exposure is in the pricing applicable to its
oil and natural gas production. Realized pricing is primarily driven by the
prevailing domestic price for oil and spot prices applicable to the Rocky
Mountain and Mid-Continent regions for its natural gas production.
Historically, prices received for oil and gas production have been volatile and
unpredictable.  Pricing volatility is expected to continue.  Natural gas price
realizations during 1999 and the first six months of 2000, exclusive of any
hedges, ranged from a monthly low of $1.51 per Mcf to a monthly high of $3.83
per Mcf.  Oil prices, exclusive of any hedges, ranged from a monthly low of
$10.70 per barrel to a monthly high of $30.55 per barrel during 1999 and the
first six months of 2000.  Both oil and natural gas prices increased
significantly from the second quarter 1999 to the second quarter of 2000.  A
significant decline in the prices of oil or natural gas could have a material
adverse effect on the Company's financial condition and results of operations.

   From time to time, the Company enters into commodity derivative contracts and
fixed-price physical contracts to manage its exposure to oil and gas price
volatility.  Commodity derivatives contracts, which are generally placed with
major financial institutions or with counterparties of high credit quality that
the Company believes are minimal credit risks, may take the form of futures
contracts, swaps or options.  The oil and gas reference prices of these
commodity derivatives contracts are based upon oil and natural gas futures which
have a high degree of historical correlation with actual prices received by the
Company.  The Company accounts for its commodity derivative contracts using the
hedge (deferral) method of accounting.  Under this method, realized gains and
losses on such contracts are deferred and recognized as an adjustment to oil and
gas sales revenues in the period in which the physical product to which the
contracts relate, is actually sold.  Gains and losses on commodity derivative
contracts that are closed before the hedged production occurs are deferred until
the production month originally hedged.

   As of June 30, 2000, the Company had entered into swap contracts for oil
(NYMEX based) for approximately 3,375 barrels of oil per day for the remainder
of 2000 at fixed prices ranging from $20.00 to $25.75 per barrel and 1,560
barrels of oil per day for 2001 at fixed prices ranging from $23.05 to $26.60
per barrel. Certain swap contracts for oil (NYMEX based) contain "knock-out"
provisions. If the average price of NYMEX WTI crude oil falls below the "knock-
out" price for the contract month, the swaps will be considered "knocked-out"
and no payment will be made to the Company for the applicable month.  These
swaps are summarized in the table below.  The overall weighted average hedged
price for the swap contracts is $22.14 per barrel for the remainder of 2000 and
$23.76 per barrel for 2001 (NYMEX based). The unrecognized losses on these
contracts totaled $6.9 million and $4.8 million based on estimated market values
at June 30, 2000 and July 25, 2000, respectively.

   As of June 30, 2000, the Company had entered into natural gas swap contracts
for approximately 32,500 MMBtu's per day for the remainder of 2000 at fixed
prices ranging from $2.06 to $3.68 per MMBtu and 18,700 MMBtu's per day for the
first six months of 2001 at fixed prices ranging from $2.55 to $3.71 per MMBtu
on CIG index based swap contracts. The Company also has entered into physical
natural gas sale contracts for the delivery of approximately 10,900 MMBtu's per
day for the remainder of 2000 at prices ranging from $2.29 to $3.04 per MMBtu
and 1,200 MMBtu's per day for the first six months of 2001 at prices ranging
from $2.67 to $3.08 per MMBtu. The weighted average daily

                                       22
<PAGE>

volumes and prices for these natural gas swaps and physical contracts are 43,400
MMBtu's per day at $2.48 per MMBtu for the remainder of 2000 and 19,900 MMBtu's
per day at $3.01 per MMBtu for the first six months of 2001. The unrecognized
losses on the swap contracts totaled $10.8 million and $5.7 million based on
estimated market values at June 30, 2000 and July 25, 2000, respectively.

   As of July 25, 2000, the Company was a party to the following fixed price
swap and physical arrangements summarized by quarter:

Inflation and Changes in Prices

   While certain costs are affected by the general level of inflation, factors
unique to the oil and natural gas industry result in independent price
fluctuations.  Over the past five years, significant fluctuations have occurred
in oil and natural gas prices.  Although it is particularly difficult to
estimate future prices of oil and natural gas, price fluctuations have had, and
will continue to have, a material effect on the Company.

   The following table indicates the average oil and natural gas prices received
over the last five years and highlights the price fluctuations by quarter for
1999 and the first two quarters of 2000.  Average price computations exclude
hedging gains and losses and other nonrecurring items to provide comparability.
Average prices per Mcfe indicate the composite impact of changes in oil and
natural gas prices.  Oil production is converted to natural gas equivalents at
the rate of one barrel per six Mcf.
