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, is a rapidly growing independent energy company
engaged in the acquisition, development and exploitation of oil and natural gas properties within the continental United States. The Companys properties and oil and gas reserves are principally located in long-lived fields with
well-established production histories. The properties are primarily concentrated in the Wattenberg Field (Wattenberg) of Colorados Denver-Julesburg Basin (D-J Basin), the Mid Continent region of southern Oklahoma and
the Texas Panhandle, and the San Juan Basin in New Mexico. The Company was formed in 1996 to hold the assets of Snyder Oil Corporation (SOCO) in Wattenberg and to facilitate the acquisition of a competitor in the Field. In conjunction
with the acquisition, SOCO received 43.8 million common shares of Patina. In 1997, a series of transactions eliminated SOCOs ownership in the Company.



Over the past two years, the Company has made a series of acquisitions in an effort to expand and diversify its asset base. In November 2000, Patina
acquired various property interests out of bankruptcy. The assets were acquired through Elysium Energy, L.L.C. (Elysium), a New York limited liability company, in which Patina held a 50% interest. In January 2003, the Company purchased
the remaining 50% interest in Elysium for $23.1 million. In November 2002, Patina acquired the stock of Le Norman Energy Corporation (Le Norman) for $62.0 million and the issuance of 513,200 shares of the Companys Common Stock. The
Le Norman properties are located primarily in the Anadarko and Ardmore-Marietta Basins of Oklahoma and primarily produce oil. The acquisition included a 30% reversionary interest in Le Norman Partners (LNP). In December 2002, Patina
acquired Bravo Natural Resources, Inc. (Bravo) for $119.0 million. The Bravo properties are primarily located in Hemphill County, Texas and Custer and Caddo Counties of western Oklahoma, within the Anadarko Basin, and primarily produce
gas. In March 2003, Patina acquired the remaining 70% interest in LNP for $39.7 million. The LNP properties are located in Stephens, Garvin, and Carter Counties of southern Oklahoma and primarily produce oil. In October 2003, the Company acquired
the assets of Cordillera Energy Partners, LLC (Cordillera) for $243.0 million, comprised of $239.0 million and the issuance of five year warrants to purchase 1,000,000 shares of Common Stock for $22.50 per share. The Cordillera
properties are primarily located in the Mid Continent, the San Juan Basin, and the Permian Basin, and primarily produce gas. See Note (3).



The accompanying 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 Companys business involves the acquisition, development, exploitation of and production from oil and gas properties. Historically, Patinas properties were primarily located in the Wattenberg Field of Colorados D-J
Basin. Through the Le Norman, LNP, Bravo, certain Cordillera property acquisitions (collectively, Mid Continent) and Elysium (Central and Other), the Company currently has oil and gas properties in central Kansas, the
Illinois Basin, Texas, Oklahoma and New Mexico. Based on year-to-date 2004 production, Wattenberg accounted for approximately 63%, Mid Continent for 26%, San Juan for 3% and Central and Other for 8% of oil and gas production volumes on an equivalent
basis.



|(2) | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
|--- | ------------------------------------------



Producing Activities



The Company utilizes the successful efforts method of accounting for its oil and gas properties. Leasehold costs are capitalized when incurred. Unproved
properties are assessed periodically within specific geographic areas and impairments are charged to expense. Exploratory expenses, including geological and geophysical expenses and delay rentals, are charged to expense as incurred. Exploratory
drilling costs are capitalized, but charged to expense if 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 associated oil and gas reserves. Oil is converted to natural gas equivalents (Mcfe) at the rate of one barrel to six Mcf.

---

The Company follows the provisions of Statement of Financial Accounting Standards No. 144 (SFAS
144), Accounting for the Impairment or Disposal of Long-Lived Assets, which requires assessing the need for an impairment of capitalized costs of oil and gas properties on a field-by-field basis. When the net book value of
properties exceeds their projected undiscounted future cash flows, the cost of the property is written down to fair value, which is determined using discounted future cash flows on a field-by field basis. While no impairments have been
necessary since 1997, changes in oil and gas prices, underlying assumptions including development costs, lease operating expenses, production rates, production taxes or oil and gas reserves could result in impairments in the future.



Asset Retirement Costs and Obligations



The Company adopted the provisions of Statement of Financial Accounting
Standards No. 143, Accounting for Asset Retirement Obligations, (SFAS No. 143) on January 1, 2003. This statement requires that the fair value of a liability for an asset retirement obligation be recognized in the period in
which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the asset. The asset retirement liability is allocated to operating expense by using a
systematic and rational method. Upon adoption of the statement, an asset retirement obligation of $21.4 million was recorded to reflect the estimated obligations related to the future plugging and abandonment of the Companys wells. An addition
to oil and gas properties of approximately $17.2 million for the related asset retirement costs and a one-time, non-cash charge of approximately $2.6 million (net of $1.6 million of deferred taxes) was recorded for the cumulative effect of change in
accounting principle. At June 30, 2004, an asset retirement obligation of $28.0 million is recorded in Other noncurrent liabilities. A reconciliation of the changes in the liability from December 31, 2003 to June 30, 2004 follows (amounts in
thousands):

Field equipment and other



Depreciation of field equipment and other is provided
using the straight-line method over periods generally ranging from three to ten years.



Other Assets



At December 31, 2003, the
balance primarily represented $14.1 million in assets held in a deferred compensation plan and $937,000 in unamortized loan origination costs. At June 30, 2004, the balance primarily represented $22.1 million in assets held in a deferred
compensation plan, $2.2 million for the unamortized portion of an incentive compensation contribution made on behalf of certain executives to the deferred compensation plan and $468,000 in unamortized loan origination costs. See Note (7).



Revenue Recognition and Gas Imbalances



The sales method is used 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, 2003 and June 30, 2004 are believed to be insignificant. Gathering and processing costs are accounted
for as a reduction to revenue.

Accumulated Other Comprehensive Income (Loss)



The Company follows the provisions of SFAS No. 130, Reporting Comprehensive Income. In addition to net income,
comprehensive income includes all changes in equity during a period, except those resulting from investments and distributions to the owners of the Company. There were no such changes prior to 2001. The components of accumulated other comprehensive
income (loss) and related tax effects for the six months ended June 30, 2004 were as follows (in thousands):

Comprehensive income (loss) for the
three months ended June 30, 2003 and 2004 totaled ($6.9) million and $8.1 million, respectively. Comprehensive income for the six months ended June 30, 2003 and 2004 totaled $265,000 and $2.0 million, respectively.



Financial Instruments



The book value and estimated fair value of cash and equivalents was $545,000 and $1.7 million at December 31, 2003 and June
30, 2004, respectively. The book value and estimated fair value of bank debt was $416.0 million and $366.0 million at December 31, 2003 and June 30, 2004, respectively. The book value of these assets and liabilities approximates fair value due to
the short maturity or floating rate structure of these instruments.



Derivative Instruments and Hedging Activities



The Company periodically enters into derivative contracts to help manage its exposure to changes in interest rates. The contracts are placed with major financial institutions which management believes to be of high credit quality. During
the fourth quarter of 2003, the Company entered into LIBOR swap contracts to fix the interest rate on $100.0 million of LIBOR based floating rate bank debt for one year and an additional $100.0 million for two years. At June 30, 2004, the net
unrealized pretax gains on these contracts totaled $1.2 million ($738,000 gain net of $452,000 of deferred taxes) based on LIBOR futures prices at June 30, 2004. These interest rate swap contracts have been designated as cash flow hedges.



The Company regularly enters into derivative contracts and
fixed-price physical contracts to help manage its exposure to oil and gas price volatility. The contracts, which are generally placed with major financial institutions or with counter parties which management believes to be of high credit quality,
may take the form of futures contracts, swaps or options. The oil and gas reference prices of these contracts are based on oil and natural gas futures, which have a high degree of historical correlation with actual prices received by the Company.
Currently, all oil and gas swap contracts have been designated as cash flow hedges.



The Company was a party to various swap contracts for oil based on NYMEX prices for the first six months of 2003 and 2004, recognizing losses of $11.8 million and $29.5 million, respectively, related to these
contracts. The Company was a party to various swap contracts for natural gas based on the Colorado Interstate Gas (CIG), ANR Pipeline Oklahoma (ANR), Panhandle Eastern Pipeline (PEPL), and the El Paso San Juan
(EPSJ) indexes during the first six months of 2003 and 2004, recognizing losses of $12.4 million and $22.0 million, respectively, related to these contracts.



At June 30, 2004, the Company was a party to swap contracts for oil based on NYMEX prices covering approximately 14,800
barrels of oil per day for the remainder of 2004 at fixed prices ranging from $23.04 to $27.22 per barrel. These swaps are summarized in the table below. The overall weighted average hedged price for the swap contracts is $24.56 per barrel for the
remainder of 2004. The Company was also a party to swap contracts for oil for 2005 and 2006, which are summarized in the table below. The net unrealized pretax losses on these contracts totaled $107.2 million based on NYMEX futures prices at June
30, 2004.

At June 30, 2004, the Company was a party to swap contracts for natural gas based on CIG, EPSJ, ANR and
PEPL index prices covering approximately 134,500 MMBtus per day for the remainder of 2004 at fixed prices ranging from $2.83 to $5.95 per MMBtu. The overall weighted average hedged price for the swap contracts is $4.04 per MMBtu for the
remainder of 2004. The Company was also a party to natural gas swap contracts for 2005 and 2006, which are summarized in the table below. The net unrealized pretax losses on these contracts totaled $98.9 million based on futures prices at June 30,
2004.



At June 30, 2004, the Company was a party to the fixed price swaps
summarized below.

The Company is required to provide margin deposits to certain counterparties when the unrealized losses on its oil and gas hedges exceed specified credit
thresholds. At December 31, 2003 and June 30, 2004, the Company had $9.9 million and $30.2 million, respectively, on deposit with counterparties. These amounts are included in Inventory and other in the accompanying consolidated balance sheets.



The Company follows SFAS No. 133, Accounting for
Derivative Instruments and Hedging Activities, as amended, which 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 derivatives 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 treatment. The Company adopted SFAS No. 133 in January 2001.



During the first six months of 2004, net hedging losses of $51.9 million ($32.2 million after tax) were reclassified from Accumulated other comprehensive loss to earnings and the changes in the fair value of
outstanding derivative net liabilities increased by $168.9 million ($104.7 million after tax). As the underlying prices in the Companys hedge contracts were consistent with the indices used to sell its oil and gas and determine the interest
rate on the Companys bank debt, no ineffectiveness was recognized related to its hedge contracts in the first six months of 2004.



F-10



---

As of June 30, 2004, the Company had net unrealized hedging losses of $204.9 million ($127.1 million
after tax), comprised of $719,000 of current assets, $546,000 of non-current assets, $124.7 million of current liabilities and $81.5 million of non-current liabilities. Based on futures prices as of June 30, 2004, the Company expects to reclassify
as a decrease to earnings during the next twelve months $124.0 million ($76.9 million after tax) of net unrealized hedging losses from Accumulated other comprehensive loss.



Stock Options, Awards and Deferred Compensation Arrangements



The Company accounts for its stock-based compensation plans under the principles prescribed by the Accounting Principles
Boards Opinion No. 25, Accounting for Stock Issued to Employees. Stock options awarded under the Employee Plan and the non-employee Directors Plan do not result in recognition of compensation expense. See Note (7). The Company
accounts for assets held in a deferred compensation plan in accordance with EITF 97-14. See Note (7).



Per Share Data



In June
2002 and June 2003, 5-for-4 stock dividends were paid to common stockholders. In March 2004, a 2-for-1 stock split was paid. All share and per share amounts for all periods have been restated to reflect the stock dividends and the stock split.



The Company uses weighted average shares outstanding in
calculating earnings per share. When dilutive, options and common stock issuable upon conversion of warrants are included as share equivalents using the treasury stock method and included in the calculation of diluted earnings per share. See Note
(6).



Risks and Uncertainties



Historically, oil and gas prices have experienced significant fluctuations.
Price fluctuations can result from variations in weather, levels of regional or national production and demand, availability of transportation capacity to other regions of the country, international political developments, actions by OPEC and
various other factors. Increases or decreases in prices received could have a significant impact on future results.



Other



All liquid investments with a 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 accounting principles generally accepted in the United States 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.



Recent Accounting Pronouncements



In April 2003, the FASB issued SFAS No. 149, Amendment of Statement
133 on Derivative Instruments and Hedging Activities. SFAS No. 149 amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging
activities under FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities. SFAS No. 149 was generally effective for contracts entered into or modified after June 30, 2003. The adoption of this pronouncement
did not have an impact on the Companys financial condition or results of operations.

|(3) | ACQUISITIONS
|--- | ------------



In October 2003, the assets of Cordillera Energy Partners, L.L.C. (Cordillera) were acquired for $239.0 million and the issuance of five year
warrants to purchase 1,000,000 shares of the Companys Common Stock for $22.50 per share. The Cordillera properties are located primarily in the Mid Continent, the San Juan Basin, and the Permian Basin. The Cordillera properties produce
primarily gas.



As this acquisition was recorded using the
purchase method of accounting, the results of operations from the acquisition are included with the results of the Company from the acquisition date. The table below summarizes the preliminary allocation of the purchase price of the transaction
based upon the acquisition date fair values of the assets acquired and the liabilities assumed (in thousands):

|(4) | OIL AND GAS PROPERTIES
|--- | ----------------------



The cost of oil and gas properties at December 31, 2003 and June 30, 2004 included $2.5 million and $5.3 million, respectively, in net unevaluated
leasehold and property costs to which proved reserves have not been assigned. These amounts have been excluded from amortization during the respective period. The following table sets forth costs incurred related to oil and gas properties.

The disposition of
properties in 2003 primarily related to the sale of properties in Louisiana for $8.4 million, $4.8 million for sales of certain Wattenberg properties, and $3.2 million for the sale of certain Utah properties. The disposition of properties in 2004
primarily relates to the sale of the Adams Baggett properties for $15.2 million and the sale of certain Permian Basin properties acquired in the Cordillera acquisition for $6.3 million.



In conjunction with the Cordillera acquisition in 2003, an addition to oil and gas properties for $39.8 million was recorded
as a result of the deferred tax liability for the difference between the tax basis of the properties acquired and the book basis attributed to the properties under the purchase method of accounting. See Note (3). In conjunction with the acquisition
of the remaining 70% interest in LNP in March 2003, $4.6 million representing the value assigned for the 30% reversionary interest in LNP which the Company acquired in conjunction with the Le Norman acquisition was recorded in oil and gas
properties. During 2003, the Company exchanged its interest in its Wyoming grassroots project for certain oil and gas properties in Wattenberg. No gain or loss was recognized on the exchange.



During 2003, an addition to oil and gas properties of approximately $17.2
million was recorded for the asset retirement costs related to the adoption of SFAS No. 143. During 2003 and the first six months of 2004, additions to oil and gas properties of approximately $3.8 million and $446,000, respectively, were recorded
for the estimated asset retirement costs related to new wells drilled or acquired.

The following indebtedness was outstanding on the respective dates:

In January 2003, the
Company entered into an Amended Bank Credit Agreement (the Credit Agreement). The Credit Agreement is a revolving credit facility for up to $500.0 million. The amount available under the facility is adjusted semi-annually, each May 1 and
November 1, and equaled $500.0 million at June 30, 2004. A total of $134.0 million was available under the Credit Agreement at June 30, 2004.



The Company may elect that all or a portion of the credit facility bear interest at a rate equal to: (i) the LIBOR rate for one, two, three or six months
plus a margin which fluctuates from 1.25% to 1.90%, or (ii) the prime rate plus a margin which fluctuates from 0.00% to 0.65%. The margins are determined by a debt to EBITDA ratio, as defined. The weighted average interest rate under the facility
was 2.6% during the first six months of 2004 and 2.5% at June 30, 2004.



The Credit Agreement contains financial covenants, including but not limited to a maximum total debt to EBITDA ratio, as defined, and a minimum current ratio. It also contains 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. At December 31, 2003 and June 30, 2004, the Company was in compliance with all covenants. Borrowings under the Credit Agreement mature in January 2007, but may be prepaid at anytime. The Company had
a restricted payment basket under the Credit Agreement of $93.5 million as of June 30, 2004, which may be used to repurchase equity securities, pay dividends or make other restricted payments.



Effective November 1, 2003, the Company entered into interest rate swaps for
one-year and two-year periods. Each contract is for $100.0 million principal with a fixed interest rate of 1.26% on the one-year term and 1.83% on the two-year term, respectively, 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 rates of 1.26% and 1.83% and the three-month LIBOR rate, which is reset every 90 days, is received or paid every 90 days in arrears.



Scheduled maturities of indebtedness for the next five years are zero in
2004, 2005, and 2006 and $366.0 million in the first quarter of 2007. Management intends to extend the maturity of its credit facility on a regular basis; however, there can be no assurance it will be able to do so. Cash payments for interest
totaled $2.8 million and $5.7 million during the first six months of 2003 and 2004, respectively.

|(6) | STOCKHOLDERS EQUITY
|--- | --------------------



A total of 250.0 million common shares, $0.01 par value, are authorized of which 72.7 million were issued at June 30, 2004 (Common Stock). The
Common Stock is listed on the New York Stock Exchange. In June 2002 and in June 2003, 5-for-4 stock dividends were paid to common stockholders. In March 2004, a 2-for-1 stock split was paid. All share and per share amounts for all periods have been
restated to reflect the stock dividends and the stock split. The Company has a stockholders rights plan designed to ensure that stockholders receive a fair value for their shares in the event of certain takeover attempts. The following is a
schedule of changes in the Companys outstanding Common Stock since January 1, 2003:

|(7) | EMPLOYEE BENEFIT PLANS
|--- | ----------------------



401(k) Plan



The Company maintains a profit sharing and 401(k) savings plan (the 401(k) Plan). Eligible employees may make voluntary contributions to the
401(k) Plan. In addition, the Company may, at its discretion, make matching or profit sharing contributions to the 401(k) Plan. The Company made profit sharing contributions of $801,000 in the form of 60,500 shares of Common Stock and $1.4 million
in cash for 2002 and 2003, respectively.



Deferred Compensation Plan



The Company maintains a shareholder approved deferred
compensation plan (the Plan). The Plan is available to officers and certain key employees of the Company and allows participants to defer all or a portion of their salary and annual bonuses (either in cash or Common Stock). The Company
can make discretionary matching contributions of the participants salary deferral and those assets are invested in instruments as directed by the participant. The Company can also make discretionary incentive contributions in the form of cash
or securities to participants. The Plan does not have dollar limits on tax-deferred contributions. The assets of the Plan are held in a rabbi trust (Trust) and, therefore, may be available to satisfy the claims of the Companys
creditors in the event of bankruptcy or insolvency. Participants have the ability to direct the Plan Administrator to invest their salary and bonus deferrals into pre-approved mutual funds held by the Trust. In addition, participants have the right
to request that the Plan Administrator re-allocate the portfolio of investments (i.e., cash, mutual funds, Common Stock) in the participants individual account within the Trust, however, the Plan Administrator is not required to honor such
requests. Matching contributions are made in cash or Common Stock and vest ratably over a three-year period. Participants may elect to receive their distributions in either cash or Common Stock. At June 30, 2004, the balance of the assets in the
Trust totaled $84.7 million, including 2,097,912 shares of

Common Stock valued at $62.7 million. The Company accounts for the Plan in accordance with Emerging Issues Task Force (EITF) Abstract 97-14,
Accounting for Deferred Compensation Arrangements Where Amounts Earned are Held in a Rabbi Trust and Invested.



Assets of the Trust, other than Common Stock of the Company, are invested in 11 mutual funds that cover an investment spectrum ranging from equities to
money market instruments. These mutual funds are publicly quoted and reported at market value. The Company accounts for these investments in accordance with SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities.
The Trust also holds Common Stock. The Companys Common Stock held by the Trust is classified as treasury stock in the stockholders equity section of the accompanying consolidated balance sheets, as required by accounting principles
generally accepted in the United States. The market value of the assets held by the Trust, exclusive of the market value of the shares of the Common Stock that are reflected as treasury stock, at December 31, 2003 and June 30, 2004, was $14.1
million and $22.1 million, respectively, and is classified as Other Assets in the accompanying consolidated balance sheets. The amounts payable to plan participants at December 31, 2003 and June 30, 2004, including the market value of the shares of
Common Stock that are reflected as treasury stock, was $74.9 million and $84.7 million, respectively, and is classified as Deferred Compensation Liability in the accompanying consolidated balance sheets. Approximately 2,000,000 shares or 95% of the
Common Stock held in the Plan were attributable to the Chief Executive Officer at June 30, 2004.



In accordance with EITF 97-14, all market fluctuations in value of the Trust assets have been reflected in the accompanying consolidated statements of
operations. Increases or decreases in the value of the plan assets, exclusive of the shares of Common Stock of the Company, have been included as Other revenues in the accompanying consolidated statements of operations. Increases or decreases in the
market value of the deferred compensation liability, including the shares of Common Stock of the Company held by the Trust, while recorded as treasury stock, are included as Deferred compensation adjustments in the accompanying consolidated
statements of operations. Based on changes in the total market value of the Trusts assets, the Company recorded deferred compensation adjustments of $9.9 million and $13.5 million in the first six months of 2003 and 2004, respectively.



Stock Option Plans



The Company maintains a shareholder approved stock option plan for employees
(the Employee Plan) providing for the issuance of options at prices not less than fair market value on the date of grant. Options to acquire the greater of 9.4 million shares of Common Stock or 10% of outstanding diluted common shares
may be outstanding at any time. The specific terms of grant and exercise are determinable by the Compensation Committee of the Board of Directors. The options vest in annual installments over a three-year period (30%, 60%, 100%) and expire five
years from the date of grant. The following is a summary of stock options granted under the Employee Plan:



|     |  |                |  |                         |  |                              |

The Company also
maintains a shareholder approved stock grant and option plan for non-employee Directors (the Directors Plan). The Directors Plan provides for each non-employee Director to receive Common Stock in partial payment of their
quarterly retainer. A total of 5,400 shares were issued in 2003 and 700 in the first six months of 2004. In June 2004, the Compensation Committee awarded a stock grant totaling 14,000 shares of restricted Common Stock to the non-employee directors
of the Company as a component of their annual retainer. The shares vest 30% in June 2005, 30% in June 2006 and 40% in June 2007. The Directors Plan also provides for stock options to be granted to each non-employee Director upon appointment
and upon annual re-election, thereafter. The options vest in annual installments over a three-year period (30%, 60%, 100%) and expire five years from the date of grant. The following is a summary of stock options granted under the Directors
Plan:



|     |  |                |  |                          |  |                              |

The Company applies APB Opinion No. 25, Accounting for Stock Issued to Employees, in
accounting for the plans. As all stock options have been issued at the market price on the date of grant, no compensation cost has been recognized for these stock option grants. Had compensation cost for the stock option grants been determined
consistent with SFAS No. 123, Accounting for Stock-Based Compensation, net income (in thousands) and earnings per share would have been reduced to the pro forma amounts indicated below for the three and six month periods ended June 30,
2003 and 2004, respectively.

For purposes of this table, the fair value of each option grant was estimated on the date of grant using the Black-Scholes option-pricing model with the following
weighted-average assumptions used for grants for the three months ended June 30, 2003 and 2004: dividend yields of 0.8% and 0.8%; expected volatility of 45% and 30%; risk-free interest rates of 2.3% and 3.9%; and expected lives of 3.8 years and 3.8
years, respectively. The following weighted-average assumptions were used for grants for the six months ended June 30, 2003 and 2004: dividend yields of 0.7% and 0.8%; expected volatility of 45% and 29%; risk-free interest rates of 2.7% and 3.1%;
and expected lives of 3.7 years and 3.8 years, respectively.

Current income tax expense in the six
months ended June 30, 2003 and 2004 totaled $10.8 million and $17.1 million, respectively. In 2004, the Company expects to utilize approximately $12.6 million of net operating loss carryforwards and approximately $9.1 million of alternative minimum
tax (AMT) credit to reduce current taxes.



For tax
purposes, the Company had net operating loss carryforwards of approximately $41.3 million at December 31, 2003. Utilization of these losses will be limited each year as a result of various acquisitions. The carryforwards expire from 2005 through
2023. The Company has provided a $3.2 million valuation allowance against the loss carryforwards that could expire unutilized. At December 31, 2003, the Company had AMT credit carryforwards of approximately $9.1 million that are available
indefinitely. In addition, at December 31, 2003, the Company had depletion deduction carryforwards of approximately $12.0 million that are available indefinitely. The Company paid $8.1 million and $14.6 million in federal and state taxes during the
six months ended June 30, 2003 and 2004, respectively.



|(9) | MAJOR CUSTOMERS
|--- | ---------------



During the six months ended June 30, 2004, two customers accounted for 21% and 15% of the Companys oil and gas sales. During the six months ended
June 30, 2003, two customers accounted for 23% and 14% of the Companys oil and gas sales. Accounts receivable amounts from these customers at December 31, 2003 totaled $25.4 million. 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.

|(10) | COMMITMENTS AND CONTINGENCIES
|---- | -----------------------------



The Company leases office space and certain equipment under non-cancelable operating leases. In 2003, the Company entered into a firm transportation
agreement for 4,773 MMBtus per day on a pipeline from central Wyoming to the Oklahoma panhandle. The term of the agreement extends through February 2024, at a fixed fee of $0.334 per MMBtu. Under the agreement, the Company buys and sells third
party gas at various delivery points on the pipeline. During the first six months of 2004, $157,000 was recorded as a component of other revenues in the accompanying consolidated statements of operations reflecting proceeds of $10.6 million from gas
sold, net of costs of $10.4 million.



The ruling by the
Colorado Supreme Court in Rogers v. Westerman Farm Co. in July 2001 resulted in uncertainty regarding the deductibility of certain post-production costs from payments to be made to royalty interest owners. In January 2003, the Company was
named as a defendant in a lawsuit, which plaintiff seeks to certify as a class action, based upon the Westerman ruling alleging that the Company had improperly deducted certain costs in connection with its calculation of royalty payments
relating to the Companys Colorado operations. In May 2004, the plaintiff filed an amended complaint narrowing the class of potential plaintiffs, and thereafter filed a motion seeking to certify the narrowed class as described in the amended
complaint. The Company has filed an answer to the plaintiffs amended complaint. The Company intends to oppose class certification and to vigorously defend this action. The potential liability, if any, from this claim cannot currently be
reasonably estimated, and no provision has been accrued for this matter in the Companys financial statements.



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.

|ITEM 2. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------



Overview



Patina Oil & Gas Corporation (Patina or the Company) is a rapidly growing independent energy company engaged in the
acquisition, development and exploitation of oil and natural gas properties within the continental United States. The Companys properties and oil and gas reserves are principally located in long-lived fields with well-established production
histories. The properties are primarily concentrated in the Wattenberg Field (Wattenberg) of Colorados Denver-Julesburg Basin (D-J Basin), the Mid Continent region of southern Oklahoma and the Texas Panhandle, and the
San Juan Basin in New Mexico.



The Company seeks to increase
its reserves, production, revenues, net income and cash flow in a cost-efficient manner primarily through: (i) further Wattenberg development; (ii) accelerated development of the recently acquired Mid Continent and San Juan Basin properties; (iii)
selective pursuit of further consolidation and acquisition opportunities, and (iv) generation and exploitation of exploration and development projects with a focus on projects near currently owned productive properties.



During the six months ended June 30, 2004, the Company performed well in
several key respects:



| |  | Production increased 24% from 253.1 MMcfe per day in the first six months of 2003 to 314.7 MMcfe per day in 2004. The Wattenberg properties contributed 15% and the Mid Continent
properties acquired in 2002 contributed 32% of the increase. The remainder of the increase was primarily attributable to production from the Mid Continent and the San Juan properties acquired in October 2003, representing 36% and 15%, respectively.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Revenues increased 46% from $182.4 million in the first six months of 2003 to $266.3 million in 2004 primarily due to the 24% increase in production, a 13% increase in realized oil
and gas prices and a $7.4 million gain on the sale of properties. Net income increased 68% from $44.3 million for the six months ended June 30, 2003 to $74.5 million in 2004. Cash flow from operations increased 31% from $113.7 million in the first
six months of 2003 to $148.6 million in 2004.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Based on the $210.0
million 2004 capital budget combined with the benefits of the acquisitions made in 2003, the Company expects production to increase by approximately 17% to 20% in 2004 over 2003 production levels.

Critical Accounting Policies and Estimates



The Companys discussion and analysis of its financial condition and results of operations are based on consolidated
financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that
affect the reported amounts of assets, liabilities, revenues and expenses. The Company bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ
from these estimates under different assumptions or conditions. The Company believes the following critical accounting policies reflect its more significant judgments and estimates used in the preparation of its consolidated financial statements.
Revenues from the sales of oil and gas are recognized in the period delivered. An allowance for doubtful accounts for specific receivables judged unlikely to be collected is provided. The Company utilizes the successful efforts method of accounting
for its oil and gas properties. 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 capitalized, but charged to expense if 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 through depletion, depreciation and amortization expense over the life of the associated oil and gas reserves. Oil and gas property costs are periodically
evaluated for possible impairment. Impairments are recorded when management believes that a propertys net book value is not recoverable based on current estimates of expected future cash flows. Depletion, depreciation and amortization of oil
and gas properties and the periodic assessments for impairment are based on underlying oil and gas reserve estimates and future cash flows using then current oil and gas prices combined with operating and capital development costs. There are
numerous uncertainties inherent in estimating quantities of proved oil and gas reserves and in projecting future rates of production and timing of development expenditures. The Company regularly enters into commodity derivative contracts and
fixed-price physical contracts to manage its exposure to oil and gas price volatility. The contracts, which are generally placed with major financial institutions or with counter parties which management believes to be of high credit quality, may
take the form of futures contracts, swaps or options. The oil and gas reference prices of these contracts are based upon oil and natural gas futures, which have a high degree of historical correlation with actual prices received by the Company.
Currently, the Companys oil and gas swap contracts are all designated as cash flow hedges.

Factors Affecting Financial Condition and Liquidity



Liquidity and Capital Resources



During the six months ended June 30, 2004, the Company spent $105.0 million on the further development of existing properties and $3.5 million on
acquisitions. Development expenditures included $46.3 million in Wattenberg for the drilling or deepening of 58 wells, performing 188 refracs and trifracs and three recompletions, $43.3 million on the further development of the Mid Continent (Le
Norman, Le Norman Partners, Bravo, and certain Cordillera properties) for the drilling or deepening of 76 wells and 13 recompletions, $5.6 million in the San Juan Basin for the drilling of five wells and performing two recompletions and one refrac,
and $9.8 million on other properties (primarily in Illinois and Kansas), primarily for drilling or deepening 36 wells and performing 36 recompletions. During the six month period, the Company sold its interest in the Adams Baggett project in west
Texas, certain properties in the Permian Basin and various other minor properties for a total of $23.0 million. These projects combined with the benefits of the prior year acquisitions and the continued success in production enhancement allowed
production to increase 24% over the prior year period. The decision to increase or decrease development activity is heavily dependent on the prices being received for production.



At June 30, 2004, the Company had $1.3 billion of assets. Total capitalization was $709.7 million, of which 48% was
represented by stockholders equity and 52% by bank debt. During the first six months of 2004, net cash provided by operations totaled $148.6 million, up from $113.7 million in 2003. At June 30, 2004, there were no significant commitments for
capital expenditures. A $210.0 million capital budget has been approved for 2004, of which $105.0 million had been spent as of June 30, 2004. 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, including the remaining 2004 budget, depending on available opportunities and market conditions. The Company plans to finance its ongoing development, acquisition and exploration
expenditures and additional equity 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.



The Companys primary cash requirements will be to fund development
expenditures, finance acquisitions, repurchase equity securities, repay indebtedness and satisfy general working capital needs. However, future cash flows are subject to a number of variables, including the level of production and oil and 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 until the maturity of its Credit Agreement. 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.



The following summarizes the Companys contractual obligations at June 30, 2004 and the effect such obligations are expected to have on its
liquidity and cash flow in future periods (in thousands):

In January 2003, the
Company entered into an Amended Bank Credit Agreement (the Credit Agreement). The Credit Agreement is a revolving credit facility for up to $500.0 million. The amount available under the facility is adjusted semi-annually, each May 1 and
November 1, and equaled $500.0 million at June 30, 2004. A total of $134.0 million was available under the Credit Agreement at June 30, 2004.



The Company may elect that all or a portion of the credit facility bear interest at a rate equal to: (i) the LIBOR rate for one, two, three or six months
plus a margin which fluctuates from 1.25% to 1.90%, or (ii) the prime rate plus a margin which fluctuates from 0.00% to 0.65%. The margins are determined by a debt to EBITDA ratio, as defined. The weighted average interest rate under the facility
was 2.6% during the first six months of 2004 and 2.5% at June 30, 2004.



Effective November 1, 2003, the Company entered into interest rate swaps for one-year and two-year periods. Each contract is for $100.0 million principal with a fixed interest rate of 1.26% on the one-year term and 1.83% on the two-year
term, respectively, 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 rates of 1.26% and 1.83% and the three-month LIBOR rate, which is reset
every 90 days, is received or paid every 90 days in arrears.



The Credit Agreement contains financial covenants, including but not limited to a maximum total debt to EBITDA ratio, as defined, and a minimum current ratio. It also contains 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. At June 30, 2003 and 2004, the Company was in compliance with all covenants. Borrowings under the Credit Agreement mature in January 2007, but may be prepaid at anytime. The Company had a restricted
payment basket under the Credit Agreement of $93.5 million as of June 30, 2004, which may be used to repurchase equity securities, pay dividends or make other restricted payments.



Cash Flow



The Companys principal sources of cash are operating cash flow and bank borrowings. The Companys cash flow is highly dependent on oil and gas
prices. Pricing volatility will be somewhat reduced as the Company has entered into hedging agreements covering part of its expected production for 2004, 2005, and 2006, respectively. The $105.0 million of development expenditures for the first six
months of 2004 were funded entirely with internal cash flow. The 2004 capital budget of $210.0 million, comprised primarily of $110.0 million of development expenditures in Wattenberg, $70.0 million in the Mid Continent region, $15.0 million in the
San Juan Basin, and $15.0 million on the Central and Other properties, combined with the benefits of the acquisitions made in 2003, is expected to increase production by approximately 17% to 20% over 2003 production levels. On October 1, 2003,
Cordillera was acquired for $243.0 million, comprised of $239.0 million and the issuance of five year warrants to purchase 1,000,000 shares of Common Stock for $22.50 per share. On June 30, 2004, $366.0 million was outstanding under the bank
facility. Exclusive of any other acquisitions or significant equity repurchases, management expects to reduce long-term debt and fund the development program with internal cash flow.



Net cash provided by operating activities in the six months ended June 30, 2003 and 2004 was $113.7 million and $148.6
million, respectively. Cash flow from operations increased in 2004 due to the 24% increase in production and the 13% increase in average oil and gas prices received. Lease operating expenses, production taxes, general and administrative expenses and
interest expense all increased as a result of the acquisitions made at the end of the first quarter of 2003 (Le Norman Partners), and in the fourth quarter of 2003 (Cordillera). Operating cash flows in the first six months of 2003 and 2004 were
benefited by $4.7 million and $9.9 million, respectively, due to the tax deduction generated from the exercise and same day sale of stock options.

Net cash used in investing activities in the six months ended June 30, 2003 and 2004 totaled $143.9
million and $88.2 million, respectively. The decrease in expenditures in 2004 was primarily due to a $63.8 million decrease in acquisition expenditures (the Elysium and Le Norman Partners acquisitions were made in the first quarter of 2003) and the
sale of oil and gas properties for $23.0 million in first six months of 2004, offset by an increase in development expenditures of $29.0 million, comprised primarily of increases in Wattenberg of $417,000, Mid Continent of $23.8 million and San Juan
of $5.6 million.



Net cash provided by (used in) financing
activities in the six months ended June 30, 2003 and June 30, 2004 was $30.3 million and ($59.3) million, respectively. Sources of financing have been primarily bank borrowings. During the first six months of 2003, the combination of operating cash
flow, bank borrowings of $39.0 million and $6.2 million in proceeds from the exercise of stock options, allowed the Company to fund net capital development, acquisition and exploration expenditures of $142.2 million, buy back $10.1 million in Common
Stock and pay $3.8 million in dividends. During the first six months of 2004, the combination of operating cash flow and $12.7 million in proceeds from the exercise of stock options, allowed the Company to repay $50.0 million of bank debt, fund net
capital development, acquisition and exploration expenditures of $86.2 million, repurchase $14.7 million of Common Stock and pay $7.2 million of dividends.



Capital Requirements



During the first six months of 2004, $86.2 million of capital, net of $23.0 million of property sales, was expended, including $105.0 million on
development projects, $3.5 million on acquisitions and $638,000 on exploration. Development expenditures represented approximately 59% of internal cash flow (defined as net cash provided by operations before changes in working capital). The Company
manages its development budget with the goal of funding it with internal cash flow. Based on the 2004 development budget of $210.0 million combined with the benefits of the acquisitions made in 2003, production is expected to increase by
approximately 17% to 20% in 2004 over 2003 production levels. Based on current futures prices and the hedges in place for oil and natural gas, the Company expects its capital program to be funded with internal cash flow. Exclusive of any other
acquisitions or significant equity repurchases, management expects to continue to reduce long-term debt in the second half of 2004. Development and exploration activities are highly discretionary, and, for the foreseeable future, management expects
such activities to be maintained at levels equal to or below internal cash flow.



Hedging



The Company periodically
enters into derivative contracts to help manage its exposure to changes in interest rates. The contracts are placed with major financial institutions which management believes to be of high credit quality. During the fourth quarter of 2003, the
Company entered into LIBOR swap contracts to fix the interest rate on $100.0 million of LIBOR based floating rate bank debt for one year and an additional $100.0 million for two years. At June 30, 2004, the net unrealized pretax gains on these
contracts totaled $1.2 million ($738,000 gain net of $452,000 of deferred taxes) based on LIBOR futures prices at June 30, 2004. These interest rate swap contracts have been designated as cash flow hedges.



The Company regularly enters into hedging agreements to reduce the impact on
its operations of fluctuations in oil and gas prices. All such contracts are entered into solely to manage the Companys exposure to commodity price volatility. The Companys current policy is to hedge between 50% and 75% of its estimated
production, when futures prices justify, on a rolling 12 to 36 month basis. At June 30, 2004, hedges were in place covering 77.4 Bcf of natural gas at prices averaging $4.11 per MMBtu and 11.3 million barrels of oil averaging $25.33 per barrel. The
estimated fair value of the oil and gas hedge contracts that would be realized on termination approximated a net unrealized pretax loss of $206.1 million ($127.8 million loss net of $78.3 million of deferred taxes) at June 30, 2004. The combined net
unrealized losses from the oil, gas, and interest rate hedges are presented on the accompanying consolidated balance sheet as a current asset of $719,000, a non-current asset of $546,000, a current liability of $124.7 million, and a non-current
liability of $81.5 million based on contract expirations. The oil and gas contracts settle monthly through December 2006. Gains or losses on both realized and unrealized hedging transactions are determined as the difference between the contract
price and a reference price, generally NYMEX for oil and the Colorado Interstate Gas (CIG) index, ANR Pipeline Oklahoma (ANR) index, Panhandle Eastern Pipeline (PEPL) index and El Paso San Juan (EPSJ)
index for natural gas. Transaction gains and losses are determined monthly and are included as increases or decreases in oil and gas revenues in the period the hedged production is sold. Any ineffective portion of such hedges is recognized in
earnings as it occurs. Net pretax losses relating to these derivatives totaled $24.2 million and $51.9 million in the six months ended June 30, 2003 and 2004, respectively. Effective January 1, 2001, the unrealized gains (losses) on open hedging
positions were recorded at an estimate of fair value which the Company based on a comparison of the contract price and a reference price, generally NYMEX, CIG, ANR, PEPL or EPSJ on the Companys consolidated balance sheet in Accumulated other
comprehensive loss, a component of Stockholders Equity.

Inflation and Changes in Prices



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



The following table
indicates the average oil and gas prices received over the last five years and by quarter for 2003 and 2004. 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.

Results of Operations



Three months ended June 30, 2004 compared to the three months ended June 30, 2003.



Revenues for the second quarter of 2004 totaled $128.4 million, a 39% increase from the prior year period. Net income for
the second quarter of 2004 totaled $31.8 million, an increase of 57% from 2003. The increases in revenue and net income were due to higher oil and gas prices and production.



Average daily oil and gas production in the second quarter of 2004 totaled 17,768 barrels and 211.6 MMcf (318.2 MMcfe), an
increase of 20% on an equivalent basis from the same period in 2003. The rise in production was due to the continued development activity in Wattenberg and the Mid Continent, as well as the benefits of the Cordillera acquisition made in October
2003. During the second quarter of 2004, the Company drilled or deepened 31 wells, performed 71 refracs and trifracs, and two recompletions in Wattenberg, compared to 22 new wells or deepenings, 120 refracs and five recompletions in Wattenberg in
2003. During the second quarter of 2004, the Company drilled or deepened 31 wells and performed one recompletion on its Mid Continent properties, compared to 57 new drills or deepenings and one recompletion for 2003. During the second quarter, the
Company drilled or deepened 26 wells and performed 23 recompletions on its Central and Other properties compared to 27 new drills or deepenings and 33 recompletions for 2003. Based on a $210.0 million capital budget for 2004 combined with the
benefits of the acquisitions made in 2003, the Company expects production to increase by approximately 17% to 20% in 2004 over 2003 production levels. The following table sets forth summary information with respect to oil and natural gas production
for the three months ended June 30, 2003 and 2004:

Lease operating
expenses totaled $17.6 million or $0.61 per Mcfe for the second quarter of 2004 compared to $13.9 million or $0.58 per Mcfe in the prior year period. The increase in operating expenses was primarily attributed to the 20% increase in oil and gas
production. Production taxes totaled $11.2 million or $0.39 per Mcfe in the second quarter of 2004 compared to $6.4 million or $0.27 per Mcfe in 2003. The $4.8 million increase was a result of higher oil and gas prices and production.



General and administrative expenses for the second quarter of 2004 totaled
$5.9 million, an increase of $1.7 million or 39% over the same period in 2003. The increase was largely attributed to additional employees hired in conjunction with recent acquisitions.

Interest and other expenses increased to $3.1 million in the second quarter of 2004, an increase of 62%
from the prior year period. Interest expense increased as a result of higher average debt balances in conjunction with the acquisitions made in 2003, somewhat offset by lower average interest rates. The Companys average interest rate during
the second quarter of 2004 was 2.6% compared to 2.7% in 2003.



The deferred compensation adjustment totaled $8.7 million in the second quarter of 2004, a decrease of $112,000 from the prior year period. The expense relates to the increase in value of the Companys Common Stock and other
investments held in a deferred compensation plan over 2003. The Companys Common Stock price appreciated by 14% or $3.62 per share in the second quarter of 2004 versus an increase of 22% or $2.92 per share in the second quarter of 2003.



Depletion, depreciation and amortization expense for the
second quarter of 2004 totaled $30.1 million, an increase of $6.8 million or 29% from the second quarter of 2003. Depletion expense totaled $29.0 million or $1.00 per Mcfe for the second quarter of 2004 compared to $22.3 million or $0.92 per Mcfe
for 2003. The increase in depletion expense resulted from the increase in oil and gas production in the second quarter of 2004 and revised depletion rates based on the year-end 2003 reserve report and the acquisitions made during that period.
Depreciation and amortization expense for the three months ended June 30, 2004 totaled $696,000 or $0.02 per Mcfe compared to $653,000 or $0.03 per Mcfe in the second quarter of 2003. Accretion expense related to future asset retirement obligations
(SFAS No. 143) totaled $370,000 in the second quarter of 2004 compared to $318,000 in the second quarter of 2003.



Provision for income taxes for the second quarter of 2004 totaled $19.5 million, an increase of $7.0 million from the same period in 2003. The increase
was due to higher pretax earnings. A 38% tax provision was recorded for the second quarters of 2003 and 2004.

Six months ended June 30, 2004 compared to the six months ended June 30, 2003.



Revenues for the first six months of 2004 totaled $266.3 million, a 46%
increase from the prior year period. Net income for the first six months of 2004 totaled $74.5 million, an increase of 68% from 2003. The increases in revenue and net income were due to higher oil and gas prices and production.



Average daily oil and gas production in the first six months of 2004 totaled
17,756 barrels and 208.2 MMcf (314.7 MMcfe), an increase of 24% on an equivalent basis from the prior year period. The rise in production was due to the continued development activity in Wattenberg and the Mid Continent, as well as the benefits of
the LNP and Cordillera acquisitions made in 2003. During the first six months of 2004, the Company drilled or deepened 58 wells, performed 177 refracs, 11 trifracs and three recompletions in Wattenberg, compared to 42 new wells or deepenings and 252
refracs and eight recompletions in Wattenberg in 2003. During the first six months of 2004, the Company drilled or deepened 76 wells and performed 13 recompletions on its Mid Continent properties, compared to 108 new drills or deepenings and two
recompletions for the same period in 2003. During the first six months of 2004, the Company drilled or deepened 36 wells and performed 36 recompletions on its Central and Other properties compared to 34 new drills or deepenings and 43 recompletions
for 2003. Based on a $210.0 million capital budget for 2004 combined with the benefits of the acquisitions made in 2003, the Company expects production to increase by approximately 17% to 20% in 2004 over 2003 production levels. The following table
sets forth summary information with respect to oil and natural gas production for the six months ended June 30, 2003 and 2004:

Gain on sale of
properties for the first six months of 2004 totaled $7.4 million, relating to the sale of the Adams Baggett properties in west Texas for $15.2 million.



Lease operating expenses totaled $33.3 million or $0.58 per Mcfe for the first six months of 2004 compared to $24.6 million or $0.54 per Mcfe in the prior
year period. The increase in operating expenses was primarily attributed to the 24% increase in oil and gas production. Production taxes totaled $21.8 million or $0.38 per Mcfe in the first six months of 2004 compared to $12.9 million in 2003 or
$0.28 per Mcfe. The $8.9 million increase was a result of higher oil and gas prices and production.

---

General and administrative expenses for the first six months of 2004 totaled $11.2 million, an increase
of $2.5 million or 29% over the same period in 2003. The increase was largely attributed to additional employees hired in conjunction with the recent acquisitions.



Interest and other expenses increased to $6.3 million in the first six months of 2004, an increase of 53% from the prior
year period. Interest expense increased as a result of higher average debt balances in conjunction with the acquisitions made in 2003, somewhat offset by lower average interest rates. The Companys average interest rate during the first six
months of 2004 was 2.6% compared to 2.7% in 2003.



Deferred
compensation adjustment totaled $13.5 million in the first six months of 2004, an increase of $3.5 million from the prior year period. The increase relates to the increase in value of the Companys common shares and other investments held in a
deferred compensation plan over 2003. The Companys common stock price appreciated by 22% or $5.37 per share in the first six months of 2004 versus an increase of 27% or $3.42 per share during the first six months of 2003.



Depletion, depreciation and amortization expense for the first six months of
2004 totaled $59.5 million, an increase of $15.2 million or 34% from 2003. Depletion expense totaled $57.4 million or $1.00 per Mcfe for the first six months of 2004 compared to $42.5 million or $0.93 per Mcfe for 2003. The increase in depletion
expense resulted from the 24% increase in oil and gas production in the first six months of 2004 and higher depletion rates based on the year-end 2003 reserve report and the acquisitions made during that period. Depreciation and amortization expense
for the six months ended June 30, 2004 totaled $1.4 million or $0.02 per Mcfe compared to $1.2 million or $0.03 per Mcfe in the first six months of 2003. Accretion expense related to future asset retirement obligations (SFAS No. 143) totaled
$730,000 in the first six months of 2004 compared to $628,000 in the first six months of 2003.



Provision for income taxes for the first six months of 2004 totaled $45.7 million, an increase of $16.9 million from the same period in 2003. The increase was due to higher pretax earnings. A 38% tax provision was
recorded for the first six months of 2003 and 2004.



The
Company adopted Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations, in January 2003. The cumulative effect of change in accounting principle of $2.6 million (net of $1.6 million deferred
taxes) in the first six months of 2003 reflects accretion that would have been recorded if the Company had always been under the requirements of SFAS No. 143.

Recent Accounting Pronouncements



In April 2003, the FASB issued SFAS No. 149, Amendment of Statement 133 on Derivative Instruments and Hedging
Activities. SFAS No. 149 amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities under FASB Statement No. 133,
Accounting for Derivative Instruments and Hedging Activities. SFAS No. 149 was generally effective for contracts entered into or modified after June 30, 2003. The adoption of this pronouncement did not have an impact on the
Companys financial condition or results of operations.



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



Interest Rate Risk



At June 30, 2004, $366.0 million was outstanding under the credit facility with an average interest rate of 2.5%. The Company may elect that all or a
portion of the credit facility bear interest at a rate equal to: (i) LIBOR for one, two, three or six months plus a margin which fluctuates from 1.25% to 1.90% or (ii) the prime rate plus a margin which fluctuates from 0.00% to 0.65%. The weighted
average interest rate under the facility approximated 2.6% during the first six months of 2004. Assuming no change in the amount outstanding at June 30, 2004, the annual impact on interest expense of a 10% change in the average interest rate would
be approximately $581,000, net of tax. As the interest rate is variable and is reflective of current market conditions, the carrying value approximates the fair value.



Commodity Price Risk



The Companys major market risk exposure is in the pricing applicable to its oil and 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 the Companys 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 2003 and the first six months of 2004, exclusive of any hedges, ranged from a monthly low of $3.45 per Mcf to a monthly high of $5.69 per Mcf. Oil
prices, exclusive of any hedges, ranged from a monthly low of $27.35 per barrel to a monthly high of $38.97 per barrel during 2003 and the first six months of 2004. A significant decline in prices of oil or natural gas could have a material adverse
effect on the Companys financial condition and results of operations.



In the first six months of 2004, a 10% reduction in oil and gas prices, excluding oil and gas quantities that were fixed through hedging transactions, would have reduced revenues by $9.0 million. If oil and gas
futures prices at June 30, 2004 had declined by 10%, the net unrealized pretax hedging losses at that date would have decreased by $80.8 million (from a loss of $206.1 million to a loss of $125.3 million).



The Company regularly enters into derivative contracts and fixed-price
physical contracts to help manage its exposure to oil and gas price volatility. The contracts, which are generally placed with major financial institutions or with counter parties which management believes to be of high credit quality, may take the
form of futures contracts, swaps or options. The oil and gas reference prices of these contracts are based on oil and natural gas futures, which have a high degree of historical correlation with actual prices received by the Company. Currently, all
oil and gas swap contracts have been designated as cash flow hedges.



The Company was a party to various swap contracts for oil based on NYMEX prices for the first six months of 2003 and 2004, recognizing losses of $11.8 million and $29.5 million, respectively, related to these contracts. The Company was a
party to various swap contracts for natural gas based on the Colorado Interstate Gas (CIG), ANR Pipeline Oklahoma (ANR), Panhandle Eastern Pipeline (PEPL), and the El Paso San Juan (EPSJ) indexes
during the first six months of 2003 and 2004, recognizing losses of $12.4 million and $22.0 million, respectively, related to these contracts.



At June 30, 2004, the Company was a party to swap contracts for oil based on NYMEX prices covering approximately 14,800 barrels of oil per day for the
remainder of 2004 at fixed prices ranging from $23.04 to $27.22 per barrel. These swaps are summarized in the table below. The overall weighted average hedged price for the swap contracts is $24.56 per barrel for the remainder of 2004. The Company
was also a party to swap contracts for oil for 2005 and 2006, which are summarized in the table below. The net unrealized pretax losses on these contracts totaled $107.2 million based on NYMEX futures prices at June 30, 2004.

The Company is
required to provide margin deposits to certain counterparties when the unrealized losses on its oil and gas hedges exceed specified credit thresholds. At December 31, 2003 and June 30, 2004, the Company had $9.9 million and $30.2 million,
respectively, on deposit with counterparties. These amounts are included in Inventory and other in the accompanying consolidated balance sheets.



Basis Differentials



The Company sells the majority of its gas production based on the Colorado Interstate Gas (CIG) index. The realized price of the
Companys gas and that of other Rocky Mountain producers has historically traded at a discount to NYMEX gas. This discount is referred to as a basis differential and the CIG basis differential for 2003 averaged $1.35 per MMBtu
discount from NYMEX, ranging from a discount of $0.42 per MMBtu in December 2003 to a discount of $4.12 per MMBtu in March 2003. Based on the actual indices for January 2004 through June 2004 and futures prices as of June 30, 2004, the CIG basis
differential for 2004 averages a $0.95 per MMBtu discount, ranging from a discount of $0.66 per MMBtu in February 2004 to a discount of $1.20 per MMBtu in April 2004. The decrease in the CIG basis differential is believed to be in part due to the
pipeline expansions made in 2003 primarily the Kern River expansion in May 2003, resulting in an increase in gas pipeline capacity for transportation out of the Rocky Mountain region.

Forward-Looking Statements



Certain information included in this report, other materials filed or to be filed by the Company with the Securities and
Exchange Commission (SEC), as well as information included in oral statements or other written statements made or to be made by the Company contain or incorporate by reference certain statements (other than statements of historical or
present fact) that constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.



All statements, other than statements of historical or present facts, that
address activities, events, outcomes or developments that the Company plans, expects, believes, assumes, budgets, predicts, forecasts, estimates, projects, intends or anticipates (and other similar expressions) will or may occur in the future are
forward-looking statements. These forward-looking statements are based on managements current belief, based on currently available information, as to the outcome and timing of future events. When considering forward-looking statements, you
should keep in mind the risk factors and other cautionary statements in this Form 10-Q and presented in the Companys Annual Report on Form 10-K for the year ended December 31, 2003. Such forward-looking statements appear in a number of places
and include statements with respect to, among other things, such matters as: future capital availability, development and exploration expenditures (including the amount and nature thereof), drilling, deepening or refracing or trifracing of wells,
oil and gas reserve estimates (including estimates of future net revenues associated with such reserves and the present value of such future net revenues), estimates of future production of oil and natural gas, expected results or benefits
associated with recent acquisitions, business strategies, expansion and growth of the Companys operations, cash flow and anticipated liquidity, grassroots prospects and development and property acquisitions, obtaining financial or industry
partners for prospect or program development, or marketing of oil and natural gas. We caution you that these forward-looking statements are subject to all of the risks and uncertainties, many of which are beyond our control, incident to the
exploration for and development, production and sale of oil and gas. These risks include but are not limited to: general economic conditions, the market price of oil and natural gas, the risks associated with exploration, the Companys ability
to find, acquire, market, develop and produce new properties, operating hazards attendant to the oil and gas business, uncertainties in the estimation of proved reserves and in the projection of future rates of production and timing of development
expenditures, the performance by third parties of contractual obligations, the effect of gathering system problems or maintenance on our production, the strength and financial resources of the Companys competitors, the Companys ability
to find and retain skilled personnel, climatic conditions, labor relations, availability and cost of material and equipment, environmental risks, the results of financing efforts, regulatory developments and the other risks described in this Form
10-Q and presented in the Companys Annual Report on Form 10-K for the year ended December 31, 2003.



Reserve engineering is a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way. The
accuracy of any reserve estimate depends on the quality of available data and the interpretation of that data by geological engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that
were made previously. If significant, these revisions could change the schedule of any further production and/or development drilling. Accordingly, reserve estimates are generally different from the quantities of oil and natural gas that are
ultimately recovered.



Should one or more of the risks or
uncertainties described above or elsewhere in this Form 10-Q or presented in the Companys Annual Report on Form 10-K for the year ended December 31, 2003 occur, or should underlying assumptions prove incorrect, our actual results and plans
could differ materially from those expressed in any forward-looking statements. We specifically disclaim all responsibility to publicly update any information contained in a forward-looking statement or any forward-looking statement in its entirety
and therefore disclaim any resulting liability for potentially related damages.



All forward-looking statements attributable to us are expressly qualified in their entirety by this cautionary statement.
