PLAINS EXPLORATION & PRODUCTION COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Note 1  Organization and Significant Accounting
Policies

The consolidated financial statements of Plains Exploration & Production Company (PXP, us, our,
we or the Company) include the accounts of our wholly owned subsidiaries. We are an independent energy company engaged in the upstream oil and gas business of acquiring, exploiting, developing, exploring for and
producing oil and gas. Our activities are all located in the United States.

These consolidated financial statements and related notes present our
consolidated financial position as of June 30, 2006 and December 31, 2005, the results of our operations and our comprehensive income for the three months and six months ended June 30, 2006 and 2005 and our cash flows
and the changes in our stockholders equity for the six months ended June 30, 2006. All adjustments, consisting only of normal recurring adjustments, that in the opinion of management were necessary for a fair statement of the results
for the interim periods, have been reflected. All significant intercompany transactions have been eliminated. Certain reclassifications have been made to prior year financial statements to conform to the current year presentation. The results of our
operations for the six months ended June 30, 2006 are not necessarily indicative of the results of our operations to be expected for the full year.

These financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, they do not include all of the information
and notes required by accounting principles generally accepted in the United States of America for complete financial statements and should be read in conjunction with the audited consolidated financial statements included in our Annual Report on
Form 10-K for the year ended December 31, 2005.

Stone Energy Corporation. On April 24, 2006 we announced that we had entered into a
definitive agreement to acquire Stone Energy Corporation (Stone) in a stock-for-stock transaction. On June 22, 2006 the agreement was terminated by Stone in order for Stone to enter into a merger agreement with another company.
In connection with the termination of the merger agreement we received a termination fee of $43.5 million. Earnings for the three months and six months ended June 30, 2006 include a gain on the termination of the merger agreement of $37.9
million representing the termination fee net of certain merger related costs incurred by the Company.

Asset Retirement Obligations. The following
table reflects the changes in our asset retirement obligation during the six months ended June 30, 2006 (in thousands):

Stockholders Equity. Our Board of Directors has authorized the repurchase of up to $500 million
of our common stock. The shares will be repurchased from time to time in open market transactions or privately negotiated transactions at our discretion, subject to market conditions and other factors. As of June 30, 2006, no purchases had been
made under this program. In July 2006 we repurchased 2,461,900 common shares at a cost of $100.8 million.

The 254,000 shares of treasury stock at
June 30, 2006 represent shares issued to a rabbi trust for the benefit of certain of the Companys officers that retired or resigned in the first six months of 2006.

Use of Estimates. 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. Significant estimates made by management include
(1) oil and natural gas reserves; (2) depreciation, depletion and amortization, including future abandonment costs; (3) assigning fair value and allocating purchase price in connection with business combinations, including goodwill;
(4) income taxes; (5) accrued liabilities; (6) stock-based compensation and (7) valuation of derivative instruments. Although management believes these estimates are reasonable, actual results could differ from these estimates.

Stock Based Compensation. Effective January 1, 2006, we adopted Statement of Financial Accounting Standards (SFAS) No.123R
Share-Based Payment (SFAS 123R) that requires that the compensation cost relating to share-based payment transactions be recognized in financial statements. We used the modified prospective approach as allowed
under SFAS 123R. See Note 3.

Buy/Sell Contracts. Steam generators utilized in our thermal recovery operations in California are fueled by natural
gas. In certain instances we have entered into buy/sell contracts that allow us to exchange gas we produce elsewhere for gas delivered to and used in thermal recovery operations. Effective January 1, 2006 we adopted Emerging Issues Task Force
Issue No. 04-13 (EITF 04-13), Accounting for Purchases and Sales of Inventory with the Same Counterparty. EITF 04-13 requires that two or more inventory transactions with the same counterparty be viewed as a single
nonmonetary transaction if the transactions were entered into in contemplation of one another (as determined in accordance with EITF 04-13). We have determined that transactions under certain of our buy/sell contracts should be presented net in
accordance EITF 04-13. Accordingly, certain costs previously recorded gross in revenues and operating costs in prior periods will be recorded net in 2006 and subsequent periods.

Recent Accounting Pronouncements. In February 2006, the Financial Accounting Standards Board
(FASB) issued SFAS No. 155, Accounting for Certain Hybrid Financial Instruments (SFAS 155), which eliminates the exemption from applying SFAS No. 133, Accounting for Derivative Instruments and
Hedging Activities, to interests in securitized financial assets so that similar instruments are accounted for similarly regardless of the form of the instruments. SFAS 155 also allows the election of fair value measurement at acquisition, at
issuance, or when a previously recognized financial instrument is subject to a remeasurement event. Adoption is effective for all financial instruments acquired or issued after the beginning of the first fiscal year that begins after
September 15, 2006. Early adoption is permitted. The adoption of SFAS 155 is not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In March 2006, the FASB issued SFAS No. 156  Accounting for Servicing of Financial Assets (SFAS 156), which requires all
separately recognized servicing assets and servicing liabilities be initially measured at fair value. SFAS 156 permits, but does not require, the subsequent measurement of servicing assets and servicing liabilities at fair value. Adoption is
required as of the beginning of the first fiscal year that begins after September 15, 2006. Early adoption is permitted. The adoption of SFAS 156 is not expected to have a material effect on our consolidated financial position, results of
operations or cash flows.

In June 2006, the FASB issued FASB Interpretation No. 48 Accounting for Uncertainty in Income Taxes (an
interpretation of FASB Statement No. 109) which is effective for fiscal years beginning after December 15, 2006 with earlier adoption encouraged. This interpretation was issued to clarify the accounting for uncertainty in income
taxes recognized in the financial statements by prescribing a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. We are currently
evaluating the potential impact of this interpretation

Note 2Derivative Instruments and Hedging Activities

We use various derivative instruments to manage our exposure to commodity price risk on sales of oil and gas production and the purchase of natural gas used in our
thermal recovery operations. All derivative instruments are recorded on the balance sheet at fair value. If a derivative does not qualify as a hedge or is not designated as a hedge, the changes in fair value, both realized and unrealized, are
recognized currently in our income statement as a gain or (loss) on mark-to-market derivative contracts. Cash flows are only impacted to the extent the actual settlements under the contracts result in making a payment to or receiving a payment from
the counterparty. If a derivative is designated as a cash flow hedge and qualifies for hedge accounting, any unrealized gain or loss is deferred in accumulated Other Comprehensive Income (OCI), a component of Stockholders Equity,
until the hedged oil and gas production is sold. Realized gains and losses on derivative instruments that are designated as a hedge and qualify for hedge accounting are generally included in oil and gas revenues in the period the hedged volumes are
sold. Gains and losses deferred in OCI related to cash flow hedges for which hedge accounting has been discontinued remain in OCI until the related product has been delivered.

At December 31, 2005 we had collars on 22,000 barrels of oil per day for all of 2007 and 2008 with a floor price of $25.00 and an average ceiling price of $34.76. In April 2006, we executed a series of offsetting
contracts to eliminate all of these crude oil price collars at a pre-tax cost of approximately $593 million. This amount represents the fair value of the collars on the date we entered into the offsetting positions. Since the collars were not
designated as a hedge such amount has been recognized in our income statement as a loss on mark-to-market derivative contracts ($170 million in 2006 and $423 million in prior periods).

We may settle these contracts as they mature (i.e., on a monthly basis throughout 2007 and 2008) or, at our option, we may pay the amounts due at an earlier date. If the contracts are settled as they mature, our total
cost would be approximately $644 million and the $51 million in excess of the fair value on the date we entered into the offsetting positions would be recognized in our income statement as interest expense.

The average strike prices for the put options and call options do not reflect the cost to purchase such options.
The crude oil put options cost an average of $4.91 per barrel for 2006, $5.57 per barrel for 2007 and $3.35 per barrel for 2008. The natural gas call options cost an average of $1.04 per MMBtu. The premiums for the put and call options will be paid
when the options are settled.

During the three months ended June 30, 2006 and 2005 we recognized pre-tax losses of $142.9 million and
$113.9 million, respectively, from derivatives that do not qualify or were not designated for hedge accounting. During such periods we made cash payments of $25.2 million and $196.2 million, respectively, on derivatives that do not
qualify for hedge accounting that settled during the periods.

During the six months ended June 30, 2006 and 2005 we recognized pre-tax losses of
$312.2 million and $487.9 million, respectively, from derivatives that do not qualify or were not designated for hedge accounting. During such periods we made cash payments of $50.1 million and $233.2 million, respectively, on
derivatives that do not qualify for hedge accounting that settled during the periods.

Cash payments made during the three months and six months ended
June 30, 2005 include the $145.4 million we paid to eliminate our 2006 oil price collars.

Under SFAS No. 149 Amendment of Statement 133 on
Derivative Instruments and Hedging Activities, certain of our derivatives are deemed to contain a significant financing element and cash settlements with respect to such derivatives are required to be reflected as financing activities in the
Statement of Cash Flows. Cash settlements with respect to derivatives that are qualified for hedge accounting and do not have a significant financing element are reflected as operating activities in the Statement of Cash Flows. Cash settlements with
respect to derivatives that are not qualified for hedge accounting and do not have a significant financing element are reflected as investing activities in the Statement of Cash Flows.

Other Comprehensive Income

During the three months and six months ended June 30, 2006 net deferred losses
of $36.5 million and $73.1 million, respectively, attributable to cancelled 2006 swaps were reclassified from OCI and charged to oil and gas revenues. During the three months and six months ended June 30, 2005 net deferred losses
of $44.1 million and $89.3 million, respectively, were reclassified from OCI and charged to oil and gas revenues and steam gas costs and during the six months ended June 30, 2005 we recognized $0.1 million for ineffectiveness of
derivatives that qualify for hedge accounting.

At June 30, 2006 and December 31, 2005 OCI consisted of $72.7 million
($44.6 million, net of tax) and $145.8 million ($89.6 million, net of tax), respectively, of deferred losses attributable to cancelled 2006 swaps that are being reclassified to oil revenues in 2006.

Note 3Stock Based Compensation

Prior to January 1, 2006, we accounted for stock based compensation using the intrinsic value method pursuant to Accounting Principles Bulletin No. 25 Accounting for Stock Issued to Employees
(APB 25). No adjustments to our net income or earnings per share would have been required under SFAS No. 123 Accounting for Stock Based Compensation (SFAS 123). Effective January 1, 2006, we adopted the
provisions of SFAS 123R. Under the provisions of SFAS 123R, stock-based compensation is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the requisite employee service period
(generally the vesting period of the grant). We adopted SFAS 123R using the modified prospective application method, under which compensation cost is recognized in the financial statements beginning with the adoption date for all share-based
payments granted after that date, and for all unvested awards granted prior to the adoption of SFAS 123R. The cumulative adjustment at January 1, 2006 associated with the adoption of SFAS 123R resulted in a $2.2 million charge to earnings (net
of a $1.4 million tax benefit). Our paid-in capital was increased by $3.6 million and our deferred tax liability was decreased by $1.4 million.

We have
two stock incentive plans, the 2002 Stock Incentive Plan (the 2002 Plan), which provides for a maximum of 1.5 million shares available for awards, and the 2004 Stock Incentive Plan (the 2004 Plan), which provides for a
maximum of 5.0 million shares available for awards. The 2002 Plan and the 2004 Plan provide for the grant of stock options, and other awards (including performance units, performance shares, share awards, restricted stock, restricted stock
units, and stock appreciation rights, or SARs) to our directors, officers, employees, consultants and advisors. Our compensation committee may grant options and SARs on such terms, including vesting and payment forms, as it deems appropriate in its
discretion, however, no option or SARs may be exercised more than 10 years after its grant, and the purchase price for incentive stock options and non-qualified stock options may not be less than 100% of the fair market value of our common stock on
the date of grant. The compensation committee may grant restricted stock awards, restricted stock units, share awards, performance units and performance shares on such terms and conditions as it may in its discretion decide.

For the six months ended June 30, 2006 $29.0 million of stock-based compensation expense was charged to earnings ($17.5 million after a tax benefit of $11.5
million). In addition, during such period $2.7 million of stock-based compensation expense was capitalized. Additionally, there was $148.5 million of total unrecognized compensation cost related to unvested share-based compensation
arrangements that is expected to be recognized over a weighted-average period of approximately six years. The tax benefit realized as a result of the vesting of restricted stock and restricted stock unit awards during the six months ended
June 30, 2006 was $3.2 million. Stock based compensation expense for the six months ended June 30, 2006 includes $9.4 million resulting from the accelerated vesting of 0.4 million restricted stock units held by certain
former officers that resigned their positions during the period.

Estimates of fair value are not intended to predict actual future events of the value
ultimately realized by employees who receive share-based awards, and subsequent events are not indicative of the reasonableness of original estimates of fair value made by the Company under SFAS 123R.

Stock Appreciation Rights

SARs grants generally vest ratably over
three years and expire within five years after the date of grant. These awards are similar to stock options, but are settled in cash rather than in shares of common stock and are classified as liability awards. Under the provisions of SFAS 123R,
compensation cost for these awards is determined using a fair-value method and remeasured at each reporting date until the date of settlement. Stock-based compensation expense recognized in the six months ended June 30, 2006 is based on
SARs ultimately expected to vest and has been reduced for estimated forfeitures.

The total intrinsic value of SARs exercised in the six months ended June 30, 2006 was $5.6 million and
the fair value as of June 30, 2006 for SARs granted in the six months then ended was $10.40 per share.

We estimate the fair value of SARs
granted using the Black-Scholes valuation model and the fair value of the SARs are remeasured at the end of the period. The following assumptions are as of June 30, 2006:



|                         |  |              
|------------------------ |  | -------------
|Expected life (in years) |  | 1 - 4        
|Volatility               |  | 27.9% - 39.5%
|Risk-free interest rate  |  | 5.1% - 5.2%  
|Dividend yield           |  | 0%           

Expected volatility is based on the historical volatility of our common stock and other factors. We use historical
experience with exercise and post-vesting exercise behavior to determine the SARs expected life. The expected life represents the period of time that SARs granted are expected to be outstanding. The risk-free rate is based on the U.S. Treasury rate
with a maturity date corresponding to the SARs expected life.

Service Based Restricted Stock and Restricted Stock Units

Our stock compensation plans allow grants of restricted stock and restricted stock units. Restricted stock is issued on the grant date but is restricted as to
transferability. Restricted stock unit awards represent the right to receive common stock when vesting occurs.

Restricted stock and restricted stock unit
grants generally vest ratably over three years of service. Compensation cost for these awards is based on the closing market price of our common stock on the date preceding the date of grant. Stock-based compensation expense is based on the awards
ultimately expected to vest, and has been reduced for estimated forfeitures.

The following table summarizes the status of our restricted stock and
restricted stock units at June 30, 2006 and the changes during the six months then ended:

Executives Long-Term Retention and Deferred Compensation Plan

Under the terms of this plan certain executives have been granted the right to receive annual restricted stock grants beginning in 2005. Under the provisions of SFAS 123R
all such future grants are deemed granted for the purpose of determining stock-based compensation expense. At January 1, 2006 these restricted stock units were classified as equity instruments (as defined in SFAS 123R) and the valuation under
SFAS 123R was unchanged from the intrinsic valuation under APB 25.

The following table summarizes the status of these restricted stock units at
June 30, 2006 and the changes during the six months then ended:

In addition, the annual grants may be increased if certain common stock price based performance targets are
achieved. We have used a Monte-Carlo simulation model to estimate the number of restricted stock units expected to be granted in the future. This model involves forecasting potential future stock price paths based on the expected return on the
common stock and its volatility, then calculating the number of restricted stock units to be granted based on the results of the simulations.

The
following assumptions were used at June 30, 2006 with respect to the Monte Carlo simulation model:



|                         |  |       |  
|------------------------ |  | ----- | -
|Expected annual return   |  | 10.90 | %
|Expected daily return    |  | 0.04  | %
|Daily standard deviation |  | 2.19  | %

During 2006 certain of these restricted stock units were reclassified as liability instruments (as defined in SFAS
123R) and revalued under the fair value approach in accordance with the provisions of SFAS 123R instead of the previously applied intrinsic valuation method prescribed by APB 25.

Stock Options

As a result of the acquisition of Nuevo Energy Company (Nuevo) in 2004, we converted certain of Nuevos outstanding stock options to options on our common stock. At June 30, 2006 there were 133,153 options
outstanding with an average exercise price of $15.51 per share and an average remaining life of 2.9 years.

Note 4Commitments and Contingencies

Operating leases. In March 2006 we entered into an operating lease with respect to an aircraft under the terms of which we will be required
to make lease payments as follows: 2006$2.3 million, 2007 through 2010$6.1 million, and thereafter$16.0 million.

Environmental matters. As an owner or lessee and operator of oil and gas properties, we are subject to various federal, state, and local laws and regulations relating to discharge of materials into, and protection of, the
environment. Often these regulations are more burdensome on older properties that were operated before the regulations came into effect such as some of our properties in California that have operated for over 90 years. We have established policies
for continuing compliance with environmental laws and regulations. We also maintain insurance coverage for environmental matters, which we believe is customary in the industry, but we are not fully insured against all environmental risks. There can
be no assurance that current or future local, state or federal rules and regulations will not require us to spend material amounts to comply with such rules and regulations.

Plugging, Abandonment and Remediation Obligations.Consistent with normal industry practices, substantially all of
our oil and gas leases require that, upon termination of economic production, the working interest owners plug and abandon non-producing wellbores, remove tanks, production equipment and flow lines and restore the wellsite. Typically, when producing
oil and gas assets are purchased the purchaser assumes the obligation to plug and abandon wells that are part of such assets. However, in some instances, we receive an indemnity with respect to those costs. We cannot assure you that we will be able
to collect on these indemnities.

In connection with the sale of certain properties offshore California in December 2004 we retained the responsibility for
certain abandonment costs, including removing, dismantling and disposing of the existing offshore platforms. The present value of such abandonment costs, $39 million ($79 million undiscounted), are included in our asset retirement obligation as
reflected on our consolidated balance sheet. In addition, we agreed to guarantee the performance of the purchaser with respect to the remaining abandonment obligations related to the properties (approximately $44 million). The fair value of our
obligation, $0.5 million, is included in Other Long-Term Liabilities in the Consolidated Balance Sheet.

Operating risks and insurance
coverage. Our operations are subject to all of the risks normally incident to the exploration for and the production of oil and gas, including well blowouts, cratering, explosions, oil spills, releases of gas or well fluids, fires,
pollution and releases of toxic gas, each of which could result in damage to or destruction of oil and gas wells, production facilities or other property, or injury to persons. Our operations in California, including transportation of oil by
pipelines within the city and county of Los Angeles, are especially susceptible to damage from earthquakes and involve increased risks of personal injury, property damage and marketing interruptions because of the population density of southern
California. Although we maintain insurance coverage considered to be customary in the industry, we are not fully insured against all risks, either because insurance is not available or because of high premium costs. We maintain coverage for
earthquake damages in California but this coverage may not provide for the full effect of damages that could occur and we may be subject to additional liabilities. The occurrence of a significant event that is not fully insured against could have a
material adverse effect on our financial position. Our insurance does not cover every potential risk associated with operating our pipelines, including the potential loss of significant revenues. Consistent with insurance coverage generally
available to the industry, our insurance policies provide limited coverage for losses or liabilities relating to pollution, with broader coverage for sudden and accidental occurrences.

Sale of Nuevo Energy Companys Congo operations. Upon our acquisition of Nuevo Energy Company (Nuevo), we became a party to an existing agreement between Nuevo, CMS NOMECO Oil & Gas
Co. (CMS) and a third party. Under the agreement, Nuevo and CMS may be liable to the third party for the recapture of dual consolidated losses (DCLs) in connection with each companys 1995 acquisition of Congolese
properties. Nuevo and CMS agreed to indemnify each other for any act that would cause the third party to experience a liability from the recapture of DCLs as a result of a triggering event.

CMS sold its interest in the Congolese properties to a subsidiary of Perenco, S.A. (Perenco) in 2002. Both CMS and Perenco, have received from the Internal
Revenue Service, in accordance with the U.S. consolidated return regulations, a closing agreement confirming that the transaction will not trigger recapture. We and Perenco have finalized closing agreements with the IRS confirming that neither our
merger with Nuevo, nor the sale of our interest in the Congolese properties to Perenco will trigger recapture. At December 31, 2005 the estimated remaining contingent liabilities were $15.2 million relative to Nuevos former interest,
and $21.4 million relative to CMS former interest, for which we would be jointly liable. We believe the occurrence of a triggering event in the future is remote and we do not believe the agreements will have a material adverse affect upon us.

Other commitments and contingencies. As is common within the industry, we have entered into various commitments and operating agreements related to
the exploration and development of and production from proved oil and gas properties and the marketing, transportation and storage of oil. It is managements belief that such commitments will be met without a material adverse effect on our
financial position, results of operations or cash flows.

On November 15, 2005, the United States Court of Federal Claims issued a ruling granting the
plaintiffs motion for summary judgment as to liability and partial summary judgment as to damages in the breach of contract lawsuit Amber Resources Company et al. v. United States, Case No. 02-30c. The Courts ruling also
denied the United States motion to dismiss and motion for summary judgment. The United States Court of Federal Claims ruled that the federal governments imposition of new and onerous requirements that stood as a significant obstacle to
oil and gas development breached agreements that it made when it sold 36 federal leases offshore California. The Court further ruled that the Government must give back to the current lessees the more than $1.1 billion in lease bonuses it had
received at the time of sale. The final ruling in the case will not be made until the Court addresses the plaintiffs

additional claims regarding the hundreds of millions of dollars that have been spent in the successful efforts to find oil and gas in the disputed lease
area, and other matters. The final ruling, including the rulings made on November 15, 2005 will be subject to appeal, and no payments will be made until all appeals have either been waived or exhausted. We are among the current lessees of
the 36 leases. Our share of the $1.1 billion award is in excess of $80 million.

We are a defendant in various other lawsuits arising in the ordinary
course of our business. While the outcome of these lawsuits cannot be predicted with certainty and could have a material adverse effect on our financial position, we do not believe that the outcome of these legal proceedings, individually or in the
aggregate, will have a material adverse effect on our financial condition, results of operations or cash flows.

ITEM 2  Managements Discussion and Analysis of Financial Condition and Results of Operations

The following
information should be read in connection with the information contained in the consolidated financial statements and notes thereto included elsewhere in this report and our Form 10-K for the year ended December 31, 2005.

Company Overview

We are an independent oil and gas company primarily
engaged in the activities of acquiring, developing, exploiting, exploring and producing oil and gas properties in the United States. We own oil and gas properties in six states with principal operations in:



| |  |  | the Los Angeles and San Joaquin Basins onshore California;
| | - |  | ----------------------------------------------------------



| |  |  | the Santa Maria Basin offshore California;
| | - |  | ------------------------------------------



| |  |  | the Gulf Coast Basin onshore and offshore Louisiana, including the Gulf of Mexico; and
| | - |  | --------------------------------------------------------------------------------------



| |  |  | the Val Verde portion of the greater Permian Basin in Texas.
| | - |  | ------------------------------------------------------------

Assets in
our principal focus areas include mature properties with long-lived reserves and significant development and exploitation opportunities as well as newer properties with development, exploitation and exploration potential. Our primary sources of
liquidity are cash generated from our operations and our senior revolving credit facility. At June 30, 2006 we had approximately $500 million of availability under our revolving credit facility. We have a capital budget for 2006, excluding
acquisitions, of $496 million. We believe that we have sufficient liquidity through our cash from operations and borrowing capacity under our senior revolving credit facility to meet our short-term and long-term normal recurring operating needs,
derivative obligations, debt service obligations, contingencies, anticipated capital expenditures and expenditures under our stock repurchase program. In addition, the majority of our capital expenditures and expenditures under our stock repurchase
program are discretionary and could be curtailed if our cash flows declined from expected levels.

Our cash flows depend on many factors, including the
price of oil and gas, the success of our acquisition and drilling activities and the operational performance of our producing properties. We use derivative instruments to manage our commodity price risk. This practice may prevent us from receiving
the full advantage of increases in oil or gas prices above the maximum fixed amount specified in the derivative agreement. The level of derivative activity depends on our view of market conditions, available derivative prices and our operating
strategy (see  Derivative Instruments and Hedging).

Stone Energy Corporation

On April 24, 2006 we announced that we had entered into a definitive agreement to acquire Stone Energy Corporation (Stone) in a stock-for-stock
transaction. On June 22, 2006 the agreement was terminated by Stone in order for Stone to enter into a merger agreement with another company. In connection with the termination of the merger agreement we received a termination fee of $43.5
million. Earnings for the three months and six months ended June 30, 2006 include a gain on the termination of the merger agreement of $37.9 million representing the termination fee net of certain merger related costs incurred by the
Company.

Property Divestitures

On
June 28, 2006 we announced our intention to divest certain non-strategic oil and gas properties located primarily in California and Texas. High commodity prices and an active asset market prompted us to initiate the divestiture plan. We
believe the current environment provides a unique opportunity to capture asset value currently unrecognized by the equity markets. We intend to use the sales proceeds to ensure financial flexibility by reducing debt and to deliver near-term value to
shareholders by repurchasing shares of our common stock.

The properties included in the divestiture plan currently produce approximately 8,000 barrels of
oil equivalent per day. Certain properties to be offered include Buena Vista and Mt. Poso Fields in the San Joaquin Valley, Sansinena Field in the Los Angeles Basin and Pakenham Field in West Texas. The sales will be conducted in a combination of
negotiated and auction transactions and are expected to close during the fourth quarter of 2006.

Derivative Instruments and Hedging

For 2006, our crude oil derivative position consists exclusively of purchased put option contracts with a strike price of $55.00 on 50,000 barrels per day. The only cash settlements we are required to make on these
contracts are option premiums, which are expected to total approximately $7.5 million per month. In return, to the extent the daily average NYMEX price for West Texas Intermediate crude oil is less than $55.00, we will receive the difference between
$55.00 and the daily average NYMEX price for West Texas Intermediate crude oil.

In addition to our 2006 crude oil put options, we also have purchased put
option contracts with a strike price of $55.00 on 50,000 barrels per day in 2007 and 42,000 barrels per day in 2008. We also have 2006 call options on 30,000 MMBtu per day of natural gas.

At December 31, 2005 we had collars on 22,000 barrels of oil per day for all of 2007 and 2008 with a floor price of $25.00 and an average ceiling price of $34.76.
In April 2006, we executed a series of offsetting contracts to eliminate all of these crude oil price collars at a pre-tax cost of approximately $593 million. This amount represents the fair value of the collars on the date we entered into the
offsetting positions. Since the collars were not designated as a hedge, such amount has been recognized in our income statement as a loss on mark-to-market derivative contracts ($170 million in 2006 and $423 million in prior periods).

We may settle these contracts as they mature (i.e., on a monthly basis throughout 2007 and 2008) or, at our option, we may pay the amounts due at an earlier date. If the
contracts are settled as they mature, our total cost would be approximately $644 million and the $51 million in excess of the fair value on the date we entered into the offsetting positions would be recognized in our income statement as interest
expense.

Since our remaining derivative position consists entirely of crude oil put options and natural gas call options, we expect a decrease in the
volatility in derivative gains or losses on our income statement in subsequent periods.

See Item 3. Quantitative and Qualitative Disclosures About
Market Risks for a discussion of our current derivative positions.

General

We follow the full cost method of accounting whereby all costs associated with property acquisition, exploration, exploitation and development activities are capitalized. Our revenues are derived from the sale of oil,
gas and natural gas liquids. We recognize revenues when our production is sold and title is transferred. Our revenues are highly dependent upon the prices of, and demand for, oil and gas. Historically, the markets for oil and gas have been volatile
and are likely to continue to be volatile in the future. The prices we receive for our oil and gas and our levels of production are subject to wide fluctuations and depend on numerous factors beyond our control, including supply and demand, economic
conditions, foreign imports, the actions of OPEC, political conditions in other oil-producing countries, and governmental regulation, legislation and policies. Under the SECs full cost accounting rules, we review the carrying value of our
proved oil and gas properties each quarter. These rules generally require that we price our future oil and gas production at the oil and gas prices in effect at the end of each fiscal quarter to determine a ceiling value of our properties. The rules
require a write-down if our capitalized costs exceed the allowed ceiling. We have had no write-downs due to these ceiling test limitations since 1998. Given the volatility of oil and gas prices, it is likely that our estimate of
discounted future net revenues from proved oil and gas reserves will fluctuate in the near term. If oil and gas prices decline significantly in the future, write-downs of our oil and gas properties could occur. Write-downs required by these rules do
not directly impact our cash flows from operating activities. Decreases in oil and gas prices have had, and will likely have in the future, an adverse effect on the carrying value of our estimated proved reserves, our reserve volumes and our
revenues, profitability and cash flow.

Our oil and gas production expenses include salaries and benefits of personnel involved in production activities,
steam gas costs, electric costs, maintenance costs, production, ad valorem and severance taxes, and other costs necessary to operate our producing properties. Depletion of capitalized costs of producing oil and gas properties is provided using the
units of production method based upon estimated proved reserves. For the purposes of computing depletion, estimated proved reserves are redetermined as of the end of each year and on an interim basis when deemed necessary.

General and administrative expenses (G&A) consist primarily of salaries and related benefits of administrative personnel, office rent, systems costs and
other administrative costs.

Results Overview

In
the first half of 2006, primarily as a result of a $312.2 million derivative mark-to-market loss, we reported a net loss of $58.8 million, or $0.75 per share. Cash payments related to mark-to-market derivative contracts totaled $50.1 million in
the first half of 2006. Our net loss in 2006 includes a non-cash, after-tax expense related to the adoption of SFAS 123R of $2.2 million, or $0.03 per share.

Our earnings are subject to volatility due to: (i) gains and losses on derivative contracts subject to mark-to-market accounting as changes occur in the NYMEX price indexes; (ii) SARs, which are subject to variable accounting
based on changes in fair value; and (iii) beginning in 2006 as a result of the adoption of SFAS 123R certain of our restricted stock units became subject to variable accounting based on changes in fair value. The fair value of SARs and
restricted stock units is related to the market price of our common stock and will fluctuate with movements in our stock price.

In the first half of 2005,
primarily as a result of a $487.9 million derivative mark-to-market loss, we reported a net loss of $252.9 million, or $3.27 per share. Cash payments related to mark-to-market derivative contracts totaled $233.2 million in the first half of
2005.

Comparison of Three Months Ended June 30, 2006 to Three Months Ended June 30, 2005

Oil and gas revenues. Oil and gas revenues increased $61.1 million, to $277.7 million for 2006 from $216.6 million for 2005. The increase is
primarily due to higher realized prices.

Oil revenues excluding the effects of hedging, increased $80.1 million to $286.6 million for 2006 from
$206.5 million for 2005 reflecting higher realized prices ($75.2 million) and higher production ($4.9 million). Our average realized price for oil increased $15.88 to $59.44 per Bbl for 2006 from $43.56 per Bbl for 2005. The increase
is primarily attributable to an improvement in the NYMEX oil price, which averaged $70.72 per Bbl in 2006 versus $53.13 per Bbl in 2005. Oil sales volumes increased to 53.0 MBbls per day in 2006 from 52.1 MBbls per day in 2005.

Hedging had the effect of decreasing our oil revenues by $36.5 million, or $7.58 per Bbl in 2006 compared to $43.8 million or $9.24 per Bbl
in 2005. The 2006 amount represents the deferred losses related to 2006 swaps that were terminated in 2005. These losses were deferred in OCI and are being recognized as a noncash reduction to oil revenues as the hedged production is sold.

Gas revenues excluding the effects of hedging, decreased $27.1 million to $27.6 million in 2006 from $54.7 million in 2005 due to decreased
sales volumes ($14.1 million), a decrease in revenues due to a change in the presentation of certain costs related to buy-sell contracts ($8.3 million) and lower realized prices ($4.7 million). Gas revenues for 2005 include $8.3 million
attributable to buy-sell contracts related to our thermal recovery operations in California. As a result of our adoption of EITF 04-13 effective January 1, 2006 (see note 1 to the consolidated financial statements), in 2006 certain costs
associated with such contracts are reflected as a reduction in gas revenues. Our average realized price for gas was $5.83 per Mcf in 2006 compared to $6.43 per Mcf in 2005. Hedging had the effect of decreasing our 2005 gas revenues by
$0.8 million, or $0.09 per Mcf.

Gas sales volumes decreased from 78.5 MMcf per day in 2005 to 52.0 MMcf per day in 2006 primarily due
to the sale of our properties in East Texas and Oklahoma effective May 31, 2005.

Lease operating expenses. Lease operating expenses
increased $7.8 million, to $44.7 million in 2006 from $36.9 million in 2005. The increase is primarily attributable to general cost increases from service providers as well as higher expenditures for repairs and maintenance and well
workovers. On a per unit basis, lease operating expenses increased to $7.97 per BOE in 2006 versus $5.99 per BOE in 2005 due to lower volumes and increased costs.

Steam gas costs. Steam gas costs decreased $3.6 million, to $12.8 million in 2006 from $16.4 million in 2005. Steam gas costs for 2005 include certain costs ($8.3 million) attributable to
buy-sell contracts that after the adoption of EITF 04-13 would be included in gas revenues. On a basis comparable to 2006, 2005 steam gas costs would have been $8.1 million, or $1.36 per BOE, compared to $12.8 million, or $2.29 per BOE, in 2006,
primarily reflecting the increased cost of natural gas.

Electricity. Electricity increased $1.8 million, to $10.0 million in 2006
from $8.2 million in 2005, primarily reflecting higher cost for natural gas used in electricity generation, higher cost for purchased electricity and the effect of the properties acquired in the second quarter of 2005. On a per unit basis,
electricity increased to $1.77 per BOE in 2006 versus $1.33 per BOE in 2005.

Production and ad valorem taxes. Production and ad
valorem taxes increased $1.0 million, to $7.0 million in 2006 from $6.0 million in 2005 primarily reflecting the effect of increased oil and gas prices, partially offset by the properties sold in the second quarter of 2005.

Gathering and transportation expenses. Gathering and transportation expenses decreased $0.3 million, to $2.1 million in 2006 from
$2.4 million in 2005 primarily reflecting the properties sold in the second quarter of 2005.

General and administrative expense. Our
G&A expense consists of (in thousands of dollars):

##### Table of Contents

G&A expense, excluding amounts attributable to stock based compensation, was $16.8 million in 2006 compared to
$11.5 million in 2005. The 2006 expense includes $1.7 million related to officer resignations and organizational changes. The remainder of the increase from 2005 primarily reflects increased aircraft costs and increased employee headcount
and related compensation costs.

Stock based compensation expense was $21.3 million in 2006 compared to $6.8 million in 2005. Stock based
compensation costs for 2006 includes approximately $9 million related to officer resignations and organizational changes. The remainder of the increase in 2006 primarily reflects grants made subsequent to the first quarter of 2005. Certain of
the Companys stock compensation awards including SARs are subject to variable accounting and future compensation costs will be impacted by changes in the fair value of such awards.

G&A expense does not include amounts capitalized as part of our acquisition, exploration and development activities. Capitalized costs increased to $8.0 million in 2006 compared to $5.6 million in 2005,
primarily reflecting increased costs.

Depreciation, depletion and amortization, or DD&A. DD&A expense increased $5.2 million, to
$50.9 million in 2006 from $45.7 million in 2005. Approximately $4.7 million of the increase was attributable to our oil and gas DD&A, primarily due to a higher per unit rate. Our oil and gas unit of production rate increased to
$8.45 per BOE in 2006 compared to $7.18 per BOE in 2005. The increase primarily reflects the effect of property acquisitions, higher future development costs and 2005 capital costs for which there were no immediate reserve additions.

Accretion expense. Accretion expense increased $0.6 million, to $2.5 million in 2006 from $1.9 million in 2005, primarily reflecting
higher estimated future costs of our abandonment obligations.

Interest expense. Interest expense increased $5.0 million, to
$19.2 million in 2006 from $14.2 million in 2005 primarily due to higher outstanding debt and higher interest rates. Interest expense does not include interest capitalized on oil and gas properties not subject to amortization. We
capitalized $2.4 million and $0.7 million of interest in 2006 and 2005, respectively.

Gain (loss) on mark-to-market derivative contracts. We
do not use hedge accounting for certain of our derivative instruments, because the derivatives do not qualify or we have elected not to use hedge accounting. Consequently, these derivative contracts are marked-to-market each quarter with fair value
gains and losses, both realized and unrealized, recognized currently as a gain or loss on mark-to-market derivative contracts on the income statement. Cash flow is only impacted to the extent the actual settlements under the contracts result in
making or receiving a payment from the counterparty.

As a result of the significant increase in oil prices, we recognized a $142.9 million loss
related to mark-to-market derivative contracts in 2006. Cash payments related to these contracts that settled in 2006 totaled $25.2 million. In 2005 we recognized a loss on mark-to-market derivative contracts of $113.9 million. Cash payments
related to these contracts that settled in 2005 totaled $50.9 million.

Gain on termination of merger agreement. On April 24, 2006 we
announced that we had entered into a definitive agreement to acquire Stone in a stock-for-stock transaction. On June 22, 2006 the agreement was terminated by Stone in order for Stone to enter into a merger agreement with another company.
In connection with the termination of the merger agreement we received a termination fee of $43.5 million. The gain recognized in 2006 reflects the termination fee net of certain merger related costs incurred by the Company.

Income taxes. During interim periods income tax expense is generally based on the estimated effective income tax rate that is expected for the entire year.
Variances in our estimated annual effective tax rate from the 35% federal statutory rate primarily result from the effect of state income taxes, changes in the estimated California apportionment factor, estimated permanent differences primarily
reflecting expenses that are not deductible because of IRS limitations and, in 2005, the beneficial effect of certain tax credits related to our enhanced oil recovery operations in California. At June 30, 2006 our estimated 2006 annual
effective tax rate was approximately 39% and at June 30, 2005 our estimated 2005 annual effective tax rate was approximately 35%.

##### Table of Contents

In the second quarter of 2005 we revised our estimated effective annual tax rate to approximately 35% from the 40%
estimated effective annual tax rate that was utilized in the first quarter of 2005. As a result, the effective tax rate for the second quarter of 2005 was approximately 1%. The change in the estimated effective annual tax rate was primarily the
result of the sales and purchases of certain oil and gas properties in the second quarter of 2005 and the effect of a permanent difference primarily resulting from the accelerated vesting of certain restricted stock units in July 2005.

Comparison of Six Months Ended June 30, 2006 to Six Months Ended June 30, 2005

Oil and gas revenues. Oil and gas revenues increased $122.4 million, to $528.2 million for 2006 from $405.8 million for 2005. The increase is
primarily due to higher realized prices.

Oil revenues excluding the effects of hedging, increased $151.5 million to $538.1 million for 2006 from
$386.6 million for 2005 reflecting higher realized prices ($129.9 million) and higher production ($21.5 million). Our average realized price for oil increased $14.19 to $56.41 per Bbl for 2006 from $42.22 per Bbl for 2005. The
increase is primarily attributable to an improvement in the NYMEX oil price, which averaged $67.12 per Bbl in 2006 versus $51.53 per Bbl in 2005. Oil sales volumes increased 2.1 MBbls per day to 52.7 MBbls in 2006 from
50.6 MBbls per day in 2005.

Hedging had the effect of decreasing our oil revenues by $73.0 million, or $7.66 per Bbl in 2006 compared to
$89.3 million or $9.75 per Bbl in 2005. The 2006 amount represents the deferred losses related to 2006 swaps that were terminated in 2005. These losses were deferred in OCI and are being recognized as a noncash reduction to oil revenues as
the hedged production is sold.

Gas revenues excluding the effects of hedging, decreased $45.2 million to $63.2 million in 2006 from
$108.4 million in 2005 due to decreased sales volumes ($40.0 million) and a decrease in revenues due to a change in the presentation of certain costs related to buy-sell contracts ($16.1 million), partially offset by higher realized prices
($10.9 million). Gas revenues for 2005 include $16.1 million attributable to buy-sell contracts related to our thermal recovery operations in California. As a result of our adoption of EITF 04-13 effective January 1, 2006 (see note 1 to
the consolidated financial statements), in 2006 certain costs associated with such contracts are reflected as a reduction in gas revenues. Our average realized price for gas was $6.86 per Mcf in 2006 compared to $6.10 per Mcf in 2005.

Gas sales volumes decreased from 83.1 MMcf per day in 2005 to 50.8 MMcf per day in 2006 primarily due to the sale of our properties in
East Texas and Oklahoma in the second quarter of 2005.

Lease operating expenses. Lease operating expenses increased $17.7 million, to
$86.9 million in 2006 from $69.2 million in 2005. The increase is primarily attributable to general cost increases from service providers as well as higher expenditures for repairs and maintenance and well workovers. On a per unit basis,
lease operating expenses increased to $7.85 per BOE in 2006 versus $5.71 per BOE in 2005 due to lower volumes and increased costs.

Steam gas
costs. Steam gas costs decreased $7.5 million, to $25.6 million in 2006 from $33.1 million in 2005. Steam gas costs for 2005 include certain costs ($16.1 million) attributable to buy-sell contracts that after the adoption of
EITF 04-13 would be included in gas revenues. On a basis comparable to 2006, 2005 steam gas costs would have been $17.0 million, or $1.46 per BOE, compared to $25.6 million, or $2.31 per BOE, in 2006, primarily reflecting the increased cost of
natural gas.

Electricity. Electricity increased $4.0 million, to $18.8 million in 2006 from $14.8 million in 2005, primarily
reflecting higher cost for natural gas used in electricity generation, higher cost for purchased electricity and the effect of the properties acquired in the second quarter of 2005. On a per unit basis, electricity increased to $1.70 per BOE in
2006 versus $1.22 per BOE in 2005.

Production and ad valorem taxes. Production and ad valorem taxes decreased $0.5 million, to
$12.8 million in 2006 from $13.3 million in 2005 primarily reflecting the properties sold in the second quarter of 2005, partially offset by the effect of increased oil and gas prices.

Gathering and transportation expenses. Gathering and transportation expenses decreased $2.2 million, to $3.7 million in 2006 from $5.9 million
in 2005 primarily reflecting the properties sold in the second quarter of 2005.

General and administrative expense. Our G&A expense
consists of (in thousands of dollars):

##### Table of Contents

G&A expense, excluding amounts attributable to stock based compensation, was $32.0 million in 2006 compared to
$23.2 million in 2005. The 2006 expense includes $2.6 million related to officer resignations and organizational changes. The remainder of the increase from 2005 primarily reflects increased aircraft costs and increased employee headcount
and related compensation costs.

Stock based compensation expense was $29.0 million in 2006 compared to $32.6 million in 2005. SARs related
expense decreased $20.4 million, primarily reflecting the effect of variable accounting, and other stock based compensation expense increased $16.8 million, including approximately $9 million related to officer resignations and organizational
changes.

G&A expense does not include amounts capitalized as part of our acquisition, exploration and development activities. Capitalized costs
increased to $15.8 million in 2006 compared to $9.8 million in 2005, primarily reflecting increased costs.

Depreciation, depletion and
amortization, or DD&A. DD&A expense increased $11.4 million, to $100.7 million in 2006 from $89.3 million in 2005. Approximately $10.3 million of the increase was attributable to our oil and gas DD&A,
primarily due to a higher per unit rate. Our oil and gas unit of production rate increased to $8.45 per BOE in 2006 compared to $7.14 per BOE in 2005. The increase primarily reflects the effect of property acquisitions, higher future
development costs and 2005 capital costs for which there were no immediate reserve additions.

Accretion expense. Accretion expense increased
$1.2 million, to $4.9 million in 2006 from $3.7 million in 2005, primarily reflecting higher estimated future costs of our abandonment obligations.

Interest expense. Interest expense increased $9.4 million, to $35.0 million in 2006 from $25.6 million in 2005 primarily due to higher outstanding debt and higher interest rates. Interest expense does not include
interest capitalized on oil and gas properties not subject to amortization. We capitalized $3.9 million and $1.4 million of interest in 2006 and 2005, respectively.

Gain (loss) on mark-to-market derivative contracts. We do not use hedge accounting for certain of our derivative instruments, because the derivatives do not qualify or we have elected not to use hedge
accounting. Consequently, these derivative contracts are marked-to-market each quarter with fair value gains and losses, both realized and unrealized, recognized currently as a gain or loss on mark-to-market derivative contracts on the income
statement. Cash flow is only impacted to the extent the actual settlements under the contracts result in making or receiving a payment from the counterparty.

As a result of the significant increase in oil prices, we recognized a $312.2 million loss related to mark-to-market derivative contracts in 2006. Cash payments related to these contracts that settled in 2006 totaled $50.1 million. In
2005 we recognized a loss on mark-to-market derivative contracts of $487.9 million. Cash payments related to these contracts that settled in 2005 totaled $87.8 million. In addition, we paid $145.4 million in connection with the elimination
of our 2006 collars.

Gain on termination of merger agreement. On April 24, 2006 we announced that we had entered into a definitive
agreement to acquire Stone in a stock-for-stock transaction. On June 22, 2006 the agreement was terminated by Stone in order for Stone to enter into a merger agreement with another company. In connection with the termination of the merger
agreement we received a termination fee of $43.5 million. The gain recognized in 2006 reflects the termination fee net of certain merger related costs incurred by the Company.

Income taxes. During interim periods income tax expense is generally based on the estimated effective income tax rate that is expected for the entire year. Variances in our estimated annual effective tax
rate from the 35% federal statutory rate primarily result from the effect of state income taxes, changes in the estimated California apportionment factor, estimated permanent differences primarily reflecting expenses that are not deductible because
of IRS limitations and, in 2005, the beneficial effect of certain tax credits related to our enhanced oil recovery operations in California. At June 30, 2006 our estimated 2006 annual effective tax rate was approximately 39% and at
June 30, 2005 our estimated 2005 annual effective tax rate was approximately 35%.

Liquidity and Capital Resources

Our primary sources of liquidity are cash generated from our operations and our revolving credit facility. At June 30, 2006 we had approximately $500 million of availability under our revolving credit
facility. We have made and will continue to make substantial capital expenditures for the acquisition, exploitation, development, exploration and production of oil and gas. We have a capital budget for 2006, excluding acquisitions, of approximately
$496 million. We believe that we have sufficient liquidity through our cash from operations and borrowing capacity under our revolving credit facility to meet our short-term and long-term normal recurring operating needs, derivative
obligations, debt service obligations, expenditures under our stock repurchase program, contingencies and anticipated capital expenditures.

Our cash flows
depend on many factors, including the price of oil and gas, the success of our acquisition and drilling activities and the operational performance of our producing properties. We use derivative instruments to manage our commodity price risk. This
practice may prevent us from receiving the full advantage of increases in oil or gas prices above the maximum fixed amount specified in the derivative agreement. The level of derivative activity depends on our view of market conditions, available
derivative prices and our operating strategy. In addition, the majority of our capital expenditures and expenditures under our stock repurchase program are discretionary and could be curtailed if our cash flows declined from expected levels.

At June 30, 2006 we had a working capital deficit of approximately $235 million. Approximately $166 million of the working capital
deficit is attributable to our commodity derivative instruments (net of related deferred income taxes). In accordance with SFAS 133, the fair value of all derivative instruments is recorded on the balance sheet. Our hedge agreements provide for
monthly settlement based on the difference between the fixed price in the contract and the actual NYMEX oil price. Cash received for the sale of physical production will be based on actual market prices and, if necessary, will be available to meet
derivative settlement obligations. None of our derivative contracts have margin requirements or collateral provisions that could require funding prior to the scheduled cash settlement date. The seven financial institutions that are contract
counterparties for our derivative commodity contracts all have Standard & Poors ratings of A or better and all seven of the financial institutions are participating lenders in our revolving credit facility. At June 30, 2006
we were in a net liability position with all such counterparties.

At December 31, 2005 we had collars on 22,000 barrels of oil per day for all of
2007 and 2008 with a floor price of $25.00 and an average ceiling price of $34.76. In April 2006, we executed a series of offsetting contracts to eliminate all of these crude oil price collars at a pre-tax cost of approximately $593 million. This
amount represents the fair value of the collars on the date we entered into the offsetting positions. Since the collars were not designated as a hedge such amount has been recognized in our income statement as a loss on mark-to-market derivative
contracts ($170 million in 2006 and $423 million in prior periods).

We may settle these contracts as they mature (i.e., on a monthly basis throughout 2007
and 2008) or, at our option, we may pay the amounts due at an earlier date. If the contracts are settled as they mature, our total cost would be approximately $644 million and the $51 million in excess of the fair value on the date we entered into
the offsetting positions would be recognized in our income statement as interest expense.

Financing Activities

At June 30, 2006 we had $231 million outstanding under the terms of our senior revolving credit facility that matures May 16, 2010, $275.0 million
principal amount of 8.75% Senior Subordinated Notes due 2012 and $250.0 million principal amount of 7.125% Senior Notes due 2014. No amounts were outstanding under the terms of our short-term credit facility.

##### Table of Contents

Net cash provided by operating activities was $405.8 million in 2006 compared to $113.5 million in 2005. The
increase in net cash provided by operating activities in 2006 is primarily a result of increased oil and gas prices, the proceeds from the termination of the merger agreement with Stone and the effect in 2005 of a $147.3 million payment to eliminate
our 2006 oil price swaps. As discussed below, certain of our derivative cash payments are classified as financing or investing activities.

Net cash used
in investing activities was $336.7 million in 2006 primarily reflecting additions to oil and gas properties of $289.4 million and derivative settlements of $42.7 million. Net cash provided by investing activities was $39.2 million in
2005 primarily reflecting property sales proceeds of $341.0 million partially offset by additions to oil and gas properties of $299.1 million. Derivative settlements related to derivatives that have not been qualified for hedge accounting and
do not contain a significant financing element are reflected as investing activities.

Net cash used in financing activities in 2006 was
$69.2 million, primarily reflecting $41.0 million in net repayments under our senior revolving credit facility and the payment of $28.6 million in financing derivative settlements. Net cash used in financing activities in 2005 was
$153.3 million, primarily reflecting $116.5 million in net borrowings under our senior revolving credit facility and the payment of $270.7 million in financing derivative settlements. Under SFAS 149, Amendment of Statement
133 on Derivative Instruments and Hedging Activities, certain of our derivatives are deemed to contain a significant financing element and cash settlements with respect to such derivatives are required to be reflected as financing activities.

Stock Repurchase Program

Our Board of Directors has
authorized the repurchase of up to $500 million of our common stock. The shares will be repurchased from time to time in open market transactions or privately negotiated transactions at our discretion, subject to market conditions and other factors.
In July 2006 we repurchased 2,461,900 common shares at a cost of $100.8 million.

Stock Appreciation Rights

We incur cash expenditures upon the exercise of SARs, but our common shares outstanding do not increase. At June 30, 2006 we had approximately 2.7 million
SARs outstanding of which 1.7 million were vested. If all of the vested SARs were exercised, based on $40.54, the price of our common stock as of June 30, 2006, we would pay $50.4 million to holders of the SARs. In the first half
of 2006 we made cash payments of $5.6 million for SARs that were exercised during that period.

Commitments and Contingencies

Contractual obligations. In March 2006 we entered into an operating lease with respect to an aircraft under the terms of which we will be required to make
lease payments as follows: 2006 - $2.3 million, 2007 and 2008 - $6.1 million, 2009 and 2010 - $6.1 million and thereafter - $16.0 million.

Critical Accounting Policies and Factors that May Affect Future Results

Based on the accounting policies that we have in place, certain
factors may impact our future financial results. Critical accounting policies related to commodity pricing and risk management activities, write-downs under full cost ceiling test rules, oil and gas reserves, stock based compensation and goodwill
are discussed in our Annual Report on Form 10-K for the year ended December 31, 2005.

Recent Accounting Pronouncements

In February 2006, the FASB issued SFAS 155 which eliminates the exemption from applying SFAS No. 133 to interests in securitized financial assets so that
similar instruments are accounted for similarly regardless of the form of the instruments. SFAS 155 also allows the election of fair value measurement at acquisition, at issuance, or when a

previously recognized financial instrument is subject to a remeasurement event. Adoption is effective for all financial instruments acquired or issued after
the beginning of the first fiscal year that begins after September 15, 2006. Early adoption is permitted. The adoption of SFAS 155 is not expected to have a material effect on our consolidated financial position, results of operations or cash
flows.

In March 2006, the FASB issued SFAS 156 which requires all separately recognized servicing assets and servicing liabilities be initially
measured at fair value. SFAS 156 permits, but does not require, the subsequent measurement of servicing assets and servicing liabilities at fair value. Adoption is required as of the beginning of the first fiscal year that begins after
September 15, 2006. Early adoption is permitted. The adoption of SFAS 156 is not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In June 2006, the FASB issued FASB Interpretation No. 48 Accounting for Uncertainty in Income Taxes (an interpretation of FASB Statement No. 109)
which is effective for fiscal years beginning after December 15, 2006 with earlier adoption encouraged. This interpretation was issued to clarify the accounting for uncertainty in income taxes recognized in the financial statements by
prescribing a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. We are currently evaluating the potential impact of this
interpretation.

Item 3  Quantitative and Qualitative Disclosures About Market Risks

Commodity Price Risk

We use various derivative instruments to manage our exposure to commodity price risk on sales of oil and gas production and the purchase of natural gas used in our
thermal recovery operations. All derivative instruments are recorded on the balance sheet at fair value. If a derivative does not qualify as a hedge or is not designated as a hedge, the changes in fair value, both realized and unrealized, are
recognized currently in our income statement as a gain or (loss) on mark-to-market derivative contracts. Cash flows are only impacted to the extent the actual settlements under the contracts result in making a payment to or receiving a payment from
the counterparty. If a derivative is designated as a cash flow hedge and qualifies for hedge accounting, any unrealized gain or loss is deferred in accumulated Other Comprehensive Income (OCI), a component of Stockholders Equity,
until the hedged oil and gas production is sold. Realized gains and losses on derivative instruments that are designated as a hedge and qualify for hedge accounting are generally included in oil and gas revenues in the period the hedged volumes are
sold. Gains and losses deferred in OCI related to cash flow hedges for which hedge accounting has been discontinued remain in OCI until the related product has been delivered.

See Note 2 to the Consolidated Financial Statements  Derivative Instruments and Hedging Activities for a discussion of our derivative activities.

At December 31, 2005 we had collars on 22,000 barrels of oil per day for all of 2007 and 2008 with a floor price of $25.00 and an average ceiling price of $34.76.
In April 2006, we executed a series of offsetting contracts to eliminate all of these crude oil price collars at a pre-tax cost of approximately $593 million. This amount represents the fair value of the collars on the date we entered into the
offsetting positions. Since the collars were not designated as a hedge such amount has been recognized in our income statement as a loss on mark-to-market derivative contracts ($170 million in 2006 and $423 million in prior periods).

We may settle these contracts as they mature (i.e., on a monthly basis throughout 2007 and 2008) or, at our option, we may pay the amounts due at an earlier date. If the
contracts are settled as they mature, our total cost would be approximately $644 million and the $51 million in excess of the fair value on the date we entered into the offsetting positions would be recognized in our income statement as interest
expense.

At June 30, 2006 we also had the following open commodity derivative positions, none of which were designated as hedging instruments:

|(1) | Since we have offsetting positions, price changes have no effect on our liability.
|--- | ----------------------------------------------------------------------------------

The fair value of the commodity derivative contracts are estimated based on quoted prices from independent reporting services compared to the contract price of the agreement, and approximate the gain or loss that
would have been realized if the contracts had been closed out at period end. All positions offset physical positions exposed to the cash market. None of these offsetting physical positions are included in the above table. Price risk sensitivities
were calculated by assuming an across-the-board 10% increase in price regardless of term or historical relationships between the contractual price of the instruments and the underlying commodity price. In the event of an actual 10% change in prompt
month prices, the fair value of our derivative portfolio would typically change less than that shown in the table due to lower volatility in out-month prices. The cost of our puts and calls is not included in the fair value of derivatives in the
foregoing table.

The seven financial institutions that are contract counterparties for our derivative commodity contracts all have Standard &
Poors ratings of A or better and all seven of the financial institutions are participating lenders in our revolving credit facility. At June 30, 2006 we were in a net liability position with all such counterparties.

Our management intends to continue to maintain derivative arrangements for a portion of our production. These contracts may expose us to the risk of financial loss in
certain circumstances. Our derivative arrangements provide us protection on the volumes if prices decline below the prices at which these derivatives are set, but ceiling prices in our derivatives may cause us to receive less revenues on the volumes
than we would receive in the absence of derivatives.

ITEM 4  Controls and Procedures

Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer (our principal executive officer) and our Chief Financial
Officer (our principal financial officer), we evaluated the effectiveness of our disclosure controls and procedures (as defined under Rules 13a-15(e) and 15d-15(e) to the Securities Exchange Act of 1934, as amended (the Exchange Act)).
Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer believe that the disclosure controls and procedures as of June 30, 2006 were effective to ensure that information we are required to disclose in the
reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms and (ii) accumulated and communicated to our management,
including our principal executive and financial officers, as appropriate to allow timely decisions regarding required disclosure.

Because of its inherent
limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, our internal control over financial reporting can provide only reasonable assurance with respect to our financial reporting and financial
statement preparation.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended June 30, 2006 that materially affected, or are reasonably likely to materially affect, our internal control
over financial reporting.
