Exhibit 99.13

ITEM 8. Financial Statements and Supplementary Data.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of Pogo Producing Company:

We have completed integrated audits of Pogo Producing Company’s consolidated financial statements and of its internal control over financial reporting as of December 31, 2006, in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, of stockholders’ equity and of cash flows present fairly, in all material respects, the financial position of Pogo Producing Company and its subsidiaries at December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Internal control over financial reporting

Also, in our opinion, management’s assessment, included in Management’s Annual Report on Internal Control Over Financial Reporting appearing under Item 9A, that the Company maintained effective internal control over financial reporting as of December 31, 2006 based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control - Integrated Framework issued by the COSO. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As described in Management’s Report on Internal Control Over Financial Reporting, management has excluded Latigo Petroleum, Inc. (Latigo) from its assessment of internal control over financial reporting as of December 31, 2006 because

Latigo was acquired in a purchase business combination during 2006. We have also excluded Latigo from our audit of internal control over financial reporting. Latigo is a wholly-owned subsidiary of the Company whose total assets and total revenues represent 16% and 5%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2006.

POGO PRODUCING COMPANY & SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Summary of Significant Accounting Policies

Nature of Operations—

Pogo Producing Company was incorporated in 1970. Pogo Producing Company and its subsidiaries (the “Company”) are engaged in oil and gas exploration, development, production and acquisition activities in the United States, both onshore principally in the states of New Mexico, Texas, Louisiana, Wyoming and Indiana, and offshore in the Gulf of Mexico (primarily in federal waters offshore Louisiana and Texas). The Company also conducts exploration activities in offshore New Zealand and Vietnam.

The Company’s results for 2006 and 2005 reflect its oil and gas exploration, development and production activities in Canada, which was acquired on September 27, 2005 and sold in 2007, as discontinued operations. The Company’s results for 2005 and 2004 reflect its oil and gas exploration, development and production activities in the Kingdom of Thailand and Hungary, which were sold in 2005, as discontinued operations. Except where noted, the discussions in the following notes relate to the Company’s continuing activities only.

Use of Estimates—

The preparation of these financial statements requires the use of certain estimates by management in determining the Company’s assets, liabilities, revenues and expenses. Actual results could differ from such estimates. Depreciation, depletion and amortization of oil and gas properties, the impairment of oil and gas properties, and the Company’s allocation of purchase price to acquired properties are all determined using estimates of oil and gas reserves. There are numerous uncertainties in estimating the quantity of reserves and in projecting the future rates of production and timing of development expenditures. Oil and gas reserve engineering must be recognized as a subjective process of estimating underground accumulations of oil and gas that cannot be measured in an exact way. Proved reserves of crude oil, condensate, natural gas and natural gas liquids are estimated quantities that geological and engineering data demonstrate with reasonable certainty to be recoverable in the future from known reservoirs under existing economic and operating conditions. Reservoirs are considered proved if economic producibility is supported by either actual production or conclusive formation test. Proved reserves do not include, for example, hydrocarbons that may be recovered from undrilled prospects or the recovery of which is otherwise subject to reasonable doubt because of uncertainty as to geology, reservoir characteristics or economic factors. Proved developed reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods or through the application of fluid injection or other improved recovery techniques confirmed by a pilot project or operation of an installed program. Proved undeveloped oil and gas reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. Proved undeveloped reserves on undrilled acreage are limited to those drilling units offsetting productive units that are reasonably certain of production when drilled and other undrilled units where it can be demonstrated with certainty that there is continuity of production from the existing productive formation. The Securities and Exchange Commission provides a complete definition of proved reserves in Rule 4-10(a) of Regulation S-X.

Principles of Consolidation—

The consolidated financial statements include the accounts of Pogo Producing Company and its subsidiaries, after elimination of all significant intercompany transactions. Majority owned subsidiaries are fully consolidated. The Company’s operating and working interests in oil and gas joint ventures are pro rata consolidated.

Revenue Recognition—

The Company follows the “sales” (takes or cash) method of accounting for oil and gas revenues. Under this method, the Company recognizes revenues on production as it is taken and delivered to its purchasers. The volumes sold may be more or less than the volumes the Company is entitled to based on its ownership interest in the property. These differences result in a condition known in the industry as a production imbalance. The Company’s crude oil and natural gas imbalances are not significant. Such imbalances are reflected as adjustments to proved reserves and future cash flows in the unaudited supplementary oil and gas data included herein.

Inventories—Tubulars—

Tubular inventories consist primarily of tubular pipe and general equipment used in the Company’s operations and are stated at the lower of average cost or market value.

Oil and Gas Activities and Depreciation, Depletion and Amortization—

The Company follows the successful efforts method of accounting for its oil and gas activities. Under the successful efforts method, lease acquisition costs and all development costs are capitalized. Proved oil and gas properties are reviewed annually or when circumstances suggest the need for such a review and, if required, the proved properties are written down to their estimated fair value. Estimated fair value includes the estimated present value of future net cash flows. Unproved properties are reviewed quarterly to determine if there has been impairment of the carrying value, with any such impairment charged to expense in the period. The evaluation of unproved properties requires management’s judgment to estimate the fair value of leasehold costs related to a given area. Drilling activities in an area by other companies may also effectively condemn unproved properties. Exploratory well costs are capitalized until the results are determined. If proved reserves are not discovered, the exploratory well costs are expensed. The following table reflects the net changes in capitalized exploratory well costs pending proved reserve determination during 2006, 2005 and 2004 (amounts expressed in millions):

	2006			2005			2004
Balance at January 1,	$	6.8		$	11.8		$	1.0
Additions to capitalized exploratory well costs pending the determination of proved reserves	18.0			6.8			10.8
Reclassifications to proved oil and gas properties	(6.8		)	(6.7		)	—
Capitalized exploratory well costs charged to expense	—			(5.1		)	—
Balance at December 31,	$	18.0		$	6.8		$	11.8

None of the exploratory well costs have been capitalized for a period of greater than one year.

Interest costs related to financing major oil and gas projects in progress are capitalized until the projects are evaluated or until the projects are substantially complete and ready for their intended use if the projects are evaluated as successful. Other exploratory costs, such as geological and geophysical costs and rental payments, are expensed as incurred. The provision for depreciation, depletion and amortization is based on the capitalized costs as determined above, and is computed on a cost center by cost center basis using the units of production method, with lease acquisition costs amortized over total proved reserves and other costs amortized over proved developed reserves. Generally, the Company establishes cost centers for its onshore oil and gas activities on the basis of a reasonable aggregation of properties with a common geologic structural feature or stratigraphic condition. The Company generally creates cost centers on a field-by-field basis for oil and gas activities in offshore areas.

The Company has from time to time disposed of certain non-core properties and other assets that it considers to be under performing, to have little or no remaining upside potential, or which face significant future expenditures that would result in an unacceptable rate of return. Refer to the captions “Net (gain) loss on sales of properties” in the Consolidated Statements of Income.

Other properties and equipment are depreciated using a straight-line method in amounts which, in the opinion of management, are adequate to allocate the cost of the properties over their estimated useful lives.

Income Taxes—

Deferred income tax assets and liabilities are recognized for temporary differences between the basis of assets and liabilities for financial reporting and tax purposes. Changes in tax legislation are included in the relevant computations in the period in which such changes are effective. Deferred tax assets are reduced by a valuation allowance for the amount of any tax benefit when the Company believes it is more likely than not that such benefits will not be realized. Note 3 contains information about the Company’s income taxes, including the components of income tax provision and the composition of deferred income tax assets and liabilities.

Price Risk Management—

The Company from time to time enters into commodity price hedging contracts with respect to its oil and gas production to achieve a more predictable cash flow, as well as reduce its exposure to price volatility. The Company follows the provisions of Statement of Financial Accounting Standards No. 133 “Accounting for Derivative Instruments and Hedging Activities” (“SFAS 133”). SFAS 133, as amended, established accounting and reporting standards requiring that every derivative instrument (including

certain derivative instruments embedded in other contracts) be recorded in the balance sheet as either an asset or liability measured at its fair value. The statement requires that changes in the derivative’s fair value be recognized currently in earnings unless specific hedge criteria are met. Special accounting for qualifying hedges allows a derivative’s gains and losses to offset related results on the hedged item in the income statement, and requires that a company must formally document, designate and assess the effectiveness of transactions that receive hedge accounting.

SFAS 133 provides that the effective portion of the gain or loss on a derivative instrument designated and qualifying as a cash flow hedging instrument be reported as a component of other comprehensive income and be reclassified into earnings in the same period during which the hedged forecasted transaction affects earnings. The remaining gain or loss on the derivative instrument (i.e. ineffectiveness,) if any, must be recognized currently in earnings as “Other” revenue or expense. To the extent the forecasted transaction in a designated and qualifying hedge relationship is no longer probable of occurring, gains and losses previously deferred in other comprehensive income are immediately reclassified to earnings under the caption “Commodity derivative income(expense).’’ For those derivative instruments that do not qualify as a cash flow hedge instrument, the Company recognizes all future changes in the fair value of these instruments in the consolidated statement of income for the period in which the change occurs under the caption “Commodity derivative income(expense).’’

Insurance Recoveries—

The Company recognizes estimated proceeds from insurance recoveries only when the amount of the recovery is determinable and when the Company believes that the proceeds are probable of recovery. When the amount of the estimated recoveries has been determined and when the Company has concluded that the recovery is probable, the recoveries are recognized in the results of operations. Business interruption proceeds are recorded as a reduction of “Other” expense and property damage recoveries are recorded as a reduction of “Lease operating expense”. During the years ended December 31, 2006, 2005, and 2004 the Company recognized $9.2 million, $40.7 million, and $11.1 million, respectively of business interruption insurance recoveries related to deferred production resulting from Hurricanes Ivan, Katrina and Rita. During the same periods, the Company recorded reductions to lease operating expense of $18.5 million, $14.5 million, and $4.9 million, respectively, for property damage recoveries.

Treasury Stock—

On January 25, 2005, the Company announced a plan to repurchase, through open market or privately negotiated transactions, not less than $275 million, or more than $375 million of its common stock. The repurchased shares were accounted for as treasury stock. As of December 31, 2006, the Company had completed the purchase of 7,310,000 shares under this plan at a total cost of $359.5 million.

Retirement and Post-Retirement Benefits—

As of December 31, 2006, the Company adopted Financial Accounting Statement (“FAS”) No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans”, which amends FAS No. 87, “Employers’ Accounting for Pensions”, No. 88, “Employers’ Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits”, No. 106, “Employers’ Accounting for Postretirement Benefits Other Than Pensions”, and No. 132(R), “Employers’ Disclosures About Pensions and Other Postretirement Benefits – an amendment of FAS Nos. 87, 88, and 106”. The Statement requires companies to recognize on their 2006 balance sheets the funded status of their pension and other postretirement benefit plans, measured as of the balance sheet date. The Statement also requires that the actuarial gains and losses and the prior service costs and credits that arise during the period be recognized, net of tax, as components of other comprehensive income; these amounts in other comprehensive income will be adjusted as they are subsequently amortized and recognized as net periodic benefit costs. See Note 12 for additional information.

Consolidated Statements of Cash Flows—

The Company considers all highly liquid investments with a maturity date of three months or less to be cash equivalents. Significant transactions may occur which do not directly affect cash balances and, accordingly, are not disclosed in the Consolidated Statements of Cash Flows. Significant non-cash transactions are disclosed in the Consolidated Statements of Shareholders’ Equity relating to shares issued as compensation and in Note 16 relating to asset retirement costs.

Foreign Currency—

The Canadian dollar is the functional currency for the Company’s Canadian operations. Accordingly, foreign exchange translation adjustments resulting from translating the Northrock financial statements from Canadian dollars to U.S. dollars are included as a separate component of other comprehensive income in shareholders’ equity on the consolidated balance sheet. Gains or losses incurred on currency transactions in other than Canadian dollars are included in the consolidated statements of income under the caption “Income From Discontinued Operations, Net of Tax” for the period in which the transactions occur.

The U.S. dollar is the functional currency for all other areas of operations of the Company. Accordingly, monetary assets and liabilities and items of income and expense denominated in a foreign currency are remeasured to U.S. dollars at the rate of exchange in effect at the end of each month or the average for the month, and the resulting gains or losses on foreign currency transactions are included in the consolidated statements of income for the period.

Prior Year Reclassifications—

Certain prior year amounts have been reclassified to conform with the current year presentation. Such reclassifications had no effect on the Company’s net income or shareholders’ equity. The Company changed the classification of “Net (gain) loss on sales of properties” from “Revenue and Other Income” to reflect it as a component of “Operating Costs and Expenses” for both the current and prior periods.

Recent Accounting Pronouncements

In September, 2006, the FASB issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The Statement is effective for financial statements issued for fiscal years beginning after November 15, 2007. The adoption of SFAS 157 is not expected to have a material impact on the Company’s financial statements.

(2) Earnings per Share

Earnings per common share (basic earnings per share) are based on the weighted average number of shares of common stock outstanding during the periods indicated. Earnings per common share and potential common share (diluted earnings per share) consider the effect of dilutive securities as set out below. Amounts are expressed in millions, except per share amounts.

	2006		2005		2004

(3) Income Taxes

The components of income from continuing operations before income taxes for each of the three years in the period ended December 31, 2006, are as follows (expressed in millions):

	2006			2005			2004
United States	$	424.0		$	417.7		$	403.8
Foreign	(6.6		)	(4.1		)	(5.9		)
Income from continuing operations before income taxes	$	417.4		$	413.6		$	397.9

The components of income tax expense (benefit) for each of the three years in the period ended December 31, 2006, are as follows (expressed in millions):

	2006			2005			2004
Current
United States	$	73.8		$	156.9		$	145.7
Foreign	(1.5		)	1.9			0.1
Deferred
United States	79.5			(6.2		)	3.1
Foreign	(112.2)		(a)	—			—
Income tax expense	$	39.6		$	152.6		$	148.9

(a) The foreign income tax benefit in 2006 is a result of statutory reductions in the Canadian federal and provincial tax rates. Generally accepted accounting principles (“GAAP”) require that the entire tax effect of a change in enacted tax rates be allocated to continuing operations.

Total income tax expense for each of the three years in the period ended December 31, 2006, differs from the amounts computed by applying the statutory federal income tax rate to income before taxes as follows (expressed as percent of pretax income):

	2006		2005		2004
Federal statutory income tax rate	35.0	%	35.0	%	35.0	%
Increases (decreases) resulting from:
Canadian income tax rate reduction	(26.9	)	—		—
State income taxes, net of federal benefits	1.5		1.7		1.5
Other	(0.1	)	0.2		0.9
	9.5	%	36.9	%	37.4	%

During 2006, the Company’s consolidated effective tax rate was 9.5%, down from 36.9% in 2005. This decrease relates to the enactment of a reduction of the Alberta and Saskatchewan provincial tax rates, in addition to a reduction in the statutory Canadian federal income tax rate, which generated a one-time deferred tax benefit of approximately $112 million. GAAP requires that the entire effect of changes in enacted tax rates be allocated to continuing operations.

The principal components of the Company’s deferred income tax assets and liabilities at December 31, 2006 and 2005 (expressed in millions) are as follows:

	December 31,
	2006			2005
Deferred tax assets:
Foreign deferred tax assets and net operating loss carry forwards	$	2.1		$	6.3
Valuation allowance of deferred tax assets and foreign net operating loss	(2.1		)	(6.3		)
Tax basis in excess of book basis for commodity derivative contracts	—			35.2
Tax basis in excess of book basis for deferred compensation and benefit plans	21.3			20.0
Net operating loss carryforwards	62.3			2.4
Other	4.9			4.3
	88.5			61.9
Deferred tax liabilities:
Book basis in excess of tax basis for oil and gas properties and equipment	(893.3		)	(549.9		)
Other	(6.7		)	(5.7		)
	(900.0		)	(555.6		)

Net deferred tax liability	$	(811.5	)	$	(493.7	)

Book basis in excess of tax basis for oil and gas properties and equipment primarily results from differing methodologies for recording property costs and depreciation, depletion and amortization under United States generally accepted accounting principles and income tax reporting. In addition, the Company recorded a deferred tax liability resulting from book and tax basis differences for corporations acquired in 2004, 2005, and 2006.

As of December 31, 2006, the Company has a U.S. net operating loss (NOL) carryforward of approximately $178 million that may be used in future years to offset taxable income. The NOL was obtained as part of the acquisition of Latigo Petroleum, Inc. The NOL is subject to certain limitations on future utilization. The Company does not anticipate that these limitations will affect the ultimate utilization of the NOL.

As of December 31, 2006, the Company has a foreign NOL carryforward of approximately $6.4 million that may be used in future years to offset foreign taxable income. The majority of these NOL carryforwards have no expiration date, however their utilization may be subject to limitations as a result of enacted tax legislation within the applicable foreign jurisdiction and their realization is dependent upon generating sufficient taxable income within the applicable foreign jurisdiction. The $2.1 million valuation allowance at December 31, 2006 was related to exploration expenses the Company incurred in its foreign operations. During 2006, the Company reduced the foreign NOL carryforwards due to the liquidation of several foreign subsidiaries.

Where the Company’s present intention is to reinvest the unremitted earnings in its foreign operations, the Company does not provide for U.S. income taxes on unremitted earnings of foreign subsidiaries. Unremitted earnings of foreign subsidiaries (principally its Canadian subsidiary) for which U.S. income taxes have not been provided are approximately $220.6 million at December 31, 2006. It is not practicable to determine the amount of U.S. income taxes that would be payable upon remittance of the assets that represent those earnings.

On October 22, 2004, the President signed the American Jobs Creation Act of 2004 (the “Act”). The Act provides a deduction for income from qualified domestic production activities, which will be phased in from 2005 through 2010. The Act also created a temporary incentive for U.S. corporations to repatriate accumulated income earned abroad by providing an 85 percent dividends received deduction for certain dividends from controlled foreign corporations. The Company adopted a Domestic Reinvestment Plan that qualifies for the temporary incentive. Based on that decision, the Company repatriated $497 million in extraordinary dividends, as defined in the Act, during the third quarter of 2005. The Company also repatriated an additional $315 million that did not qualify for the temporary incentive. As a result of the repatriation of $812 million, the Company recorded a U.S. tax expense of $24.1 million during 2005.

The Company and its subsidiaries file income tax returns in the U.S. federal and various state and foreign jurisdictions. The Company is no longer subject to U.S. federal, state, or local tax examinations by tax authorities for years prior to 2003. The Company’s Canadian subsidiary is no longer subject to examinations by Canadian taxing authorities for years prior to 2002. The

Internal Revenue Service (“IRS”) completed the examination of the Company’s U.S. income tax returns through 2003 in the fourth quarter of 2005, which resulted in a refund to the Company in 2006 of $1.4 million. The IRS also reviewed the Company’s income tax return for 2004 and indicated they do not presently intend to perform an examination of that tax return. Based on the results of the last examination, the Company does not anticipate that any adjustments made to the filings for open years would result in a material change to its financial position.

On January 1, 2007, the Company will adopt the provisions of FASB Interpretation No.48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes.” The Company has determined that no uncertain tax positions exist where the Company would be required to make additional tax payments. As a result, the Company has not recorded any additional liabilities for any unrecognized tax benefits as of December 31, 2006, and will not be required to record any on January 1, 2007.

The Company’s accounting policy is to recognize penalties and interest related to unrecognized tax benefits as income tax expense. The Company does not have an accrued liability for the payment of penalties and interest at December 31, 2006.

(4) Long-Term Debt

Long-term debt at December 31, 2006, and 2005, consists of the following (dollars expressed in millions):

	December 31,

Long-term debt	$	2,319.7		$	1,643.4

On December 16, 2004, the Company entered into a new credit agreement (the “Credit Facility”), replacing its then existing credit agreement dated as of March 8, 2001, as amended. The Credit Facility is with various financial institutions and provides for revolving credit borrowings up to a maximum principal amount of $1 billion at any one time outstanding, with borrowings not to exceed a borrowing base determined at least semiannually using the administrative agent’s usual and customary criteria for oil and gas reserve valuation, adjusted for incurrences of other indebtedness since the last redetermination of the borrowing base. As of December 31, 2006, the borrowing base was $1.5 billion. The Credit Facility provides that in specified circumstances involving an increase in ratings assigned to the Company’s debt, the Company may elect for the borrowing base limitation to no longer apply to restrict available borrowings. The Credit Facility also includes procedures for additional financial institutions selected by the Company to become lenders under the agreement, or for any existing lender to increase its commitment in an amount approved by the Company and the lender, subject to a maximum of $250 million for all such increases in commitments of new or existing lenders. Additionally, the Credit Facility permits short-term swing-line loans up to $10 million and the issuance of letters of credit up to $75 million, which in each case reduce the credit available for revolving credit borrowings. All outstanding amounts owed under the Credit Facility become due and payable no later than the final maturity date of December 16, 2009, and are subject to acceleration upon the occurrence of events of default which the Company considers usual and customary for an agreement of this type, including failure to make payments under the credit agreement, non-performance of covenants and obligations continuing beyond any applicable grace period, default in the payment of other indebtedness in excess in principal amount of $25 million or a default accelerating or permitting the acceleration of any such indebtedness, or the occurrence of a “change in control” of the Company, including the acquisition of beneficial ownership of in excess of 50% of its capital stock. If at any time the outstanding credit extended under the agreement exceeds the applicable borrowing base, the deficiency is required to be amortized in four monthly installments

commencing 90 days after the deficiency arises, and until the deficiency is eliminated, increases in some applicable interest rate margins apply.

Borrowings under the Credit Facility bear interest, at the Company’s election, at a prime rate or Eurodollar rate, plus in each case an applicable margin. In addition, a commitment fee is payable on the unused portion of each lender’s commitment. The applicable interest rate margin varies from 0% to 0.25% in the case of borrowings based on the prime rate and from 1.00% to 2.00% in the case of borrowings based on the Eurodollar rate, depending on the utilization level in relation to the borrowing base and, in the case of Eurodollar borrowings, ratings assigned to the Company’s debt.

The Credit Facility contains various covenants, including among others, restrictions on liens, restrictions on incurring other indebtedness if a default under the credit agreement exists or would result or if a borrowing base deficiency would result, restrictions on dividends and other restricted payments if a default under the credit agreement exists or would result, restrictions on mergers, restrictions on investments, and restrictions on hedging activity of a speculative nature or with counterparties having credit ratings below specified levels. Financial covenants include a covenant not to permit the Company’s ratio of consolidated debt to consolidated total capitalization (determined without reduction for any non-cash write downs after the date of the credit agreement) to exceed 60% at any time, and not to permit the Company’s consolidated ratio of EBITDAX to Fixed Charges (as those terms are defined in the Credit Facility) for the four most recent fiscal quarters to be less than or equal to 2.5 to 1.0 at the end of any quarter.

On June 6, 2006, the Company issued $450 million principal amount of 7.875% senior subordinated notes due 2013. The proceeds from the sale of the 2013 Notes were used to pay down obligations under the Company’s bank revolving credit agreement. The 2013 Notes bear interest at a rate of 7.875%, payable semi-annually in arrears on May 1 and November 1 of each year. The 2013 Notes are general unsecured senior subordinated obligations of the Company, and are subordinated in right of payment to the Company’s senior indebtedness, which currently includes the Company’s obligations under the bank revolving credit agreement and LIBOR rate advances. The Company, at its option, may redeem the 2013 Notes in whole or in part, at any time on or after May 1, 2010, at a redemption price of 103.938% of their principal amount and decreasing percentages thereafter. The Company may also redeem a portion of the 2013 Notes prior to May 1, 2009 with proceeds from equity offerings, and some or all of the Notes prior to May 1, 2010, in each case by paying specified premiums. The indenture governing the 2013 Notes also imposes certain covenants on the Company, including covenants limiting: incurrence of indebtedness, including senior indebtedness; payments of dividends, stock repurchases, and redemption of subordinated debt; the sales of assets or subsidiary capital stock; transactions with affiliates; liens; agreements restricting dividends and distributions by subsidiaries; and mergers or consolidations.

On September 23, 2005, the Company issued $500 million principal amount of 2017 Notes. The proceeds from the sale of the 2017 Notes were used to fund a portion of the Northrock acquisition. The 2017 Notes bear interest at a rate of 6.875%, payable semi-annually in arrears on April 1 and October 1 of each year. The 2017 Notes are general unsecured senior subordinated obligations of the Company, and are subordinated in right of payment to the Company’s senior indebtedness, which includes the Company’s obligations under the Credit Facility and LIBOR rate advances. The Company, at its option, may redeem the 2017 Notes in whole or in part, at any time on or after October 1, 2010, at a redemption price of 103.4375% of their principal amount and decreasing percentages thereafter. The Company may also redeem a portion of the 2017 Notes prior to October 1, 2008 and some or all of the Notes prior to October 1, 2010, in each case by paying specified premiums. The indenture governing the 2017 Notes also imposes certain covenants on the Company including covenants limiting: incurrence of indebtedness including senior indebtedness; restricted payments; the issuance and sales of restricted subsidiary capital stock; transactions with affiliates; liens; disposition of proceeds of assets sales; non-guarantor restricted subsidiaries; dividends and other payment restrictions affecting restricted subsidiaries; and merger, consolidations and the sale of assets.

On March 29, 2005, the Company issued $300 million principal amount of 2015 Notes at 99.101%. The proceeds from the sale of the 2015 Notes were used to pay down obligations under the Company’s bank Credit Facility. The 2015 Notes bear interest at a rate of 6.625%, payable semi-annually in arrears on March 15 and September 15 of each year. The 2015 Notes are general unsecured senior subordinated obligations of the Company, and are subordinated in right of payment to the Company’s senior indebtedness, which includes the Company’s obligations under the Credit Facility and LIBOR rate advances. The Company, at its option, may redeem the 2015 Notes in whole or in part, at any time on or after March 15, 2010, at a redemption price of 103.3125% of their principal amount and decreasing percentages thereafter. The Company may also redeem a portion of the 2015 Notes prior to March 15, 2008 and some or all of the Notes prior to March 15, 2010, in each case by paying specified premiums. The indenture governing the 2015 Notes also imposes certain covenants on the Company including covenants limiting: incurrence of indebtedness including senior indebtedness; restricted payments; the issuance and sales of restricted subsidiary capital stock; transactions with affiliates; liens; disposition of proceeds of asset sales; non-guarantor restricted subsidiaries; dividends and other payment restrictions affecting restricted subsidiaries; and merger, consolidations and the sale of assets.

On April 10, 2001, the Company issued $200 million principal amount of 2011 Notes. The 2011 Notes bear interest at a rate of 8.25%, payable semi-annually in arrears on April 15 and October 15 of each year. The 2011 Notes are general unsecured senior subordinated obligations of the Company, are subordinated in right of payment to the Company’s senior indebtedness, which currently includes the Company’s obligations under the Credit Facility and LIBOR rate advances. The Company, at its option, may redeem the 2011 Notes in whole or in part, at any time on or after April 15, 2006, at a redemption price of 104.125% of their principal amount and decreasing percentages thereafter. The indenture governing the 2011 Notes also imposes certain covenants on the Company including covenants limiting: incurrence of indebtedness including senior indebtedness; restricted payments; the issuance and sales of restricted subsidiary capital stock; transactions with affiliates; liens; disposition of proceeds of asset sales; non-guarantor restricted subsidiaries; dividends and other payment restrictions affecting restricted subsidiaries; and merger, consolidations and the sale of assets.

During 2004, the Company redeemed all $150 million of its 10.375% Senior Subordinated Notes due 2009 (the “2009 Notes”) at 105.188% of their face amount. On April 19, 2004, the Company paid $157.8 million (excluding accrued interest) in cash to holders of the 2009 Notes. The cash redemption payment was funded through borrowings under the Company’s existing bank Credit Facility. The Company recorded a pre-tax expense on the redemption of the 2009 Notes of $10.9 million in “Loss on debt extinguishment” during the year ended December 31, 2004.

A change in control in the ownership of the Company, as defined in the subordinated note agreements, could result in the acceleration of debt repayment. See Note 6 – “Commitments and Contingencies” for further discussion.

(5) Acquisitions

2006 - On May 2, 2006, the Company completed the acquisition of Latigo Petroleum, Inc. (“Latigo”), a privately held corporation for approximately $764.9 million in cash, including transaction costs. The purchase price was funded using cash on hand and debt financing. At the date of purchase, Latigo owned approximately 100,100 net producing acres, plus approximately 304,600 net acres of undeveloped leasehold. Latigo’s operations are concentrated in west Texas and the Texas Panhandle with key exploration plays in the Texas Panhandle. The Company acquired Latigo primarily to strengthen its position in domestic exploration and development properties. The following is a calculation and final allocation of purchase price to the acquired assets and liabilities based on their relative fair values:

CALCULATION OF PURCHASE PRICE (IN MILLIONS)
Cash paid, including transaction costs	$	764.9

Plus fair market value of liabilites assumed:
Deferred income taxes	205.9
Other liabilities	55.1
Total purchase price for assets acquired	$	1,025.9

ALLOCATION OF PURCHASE PRICE (IN MILLIONS)
Proved oil and gas properties	$	846.9
Unproved oil and gas properties	157.0
Other assets	22.0
Total	$	1,025.9

In addition to the Latigo acquisition, the Company, through its Northrock subsidiary, also completed the corporate acquisition of a Canadian company on February 21, 2006 for cash consideration totaling approximately $18.6 million. The Company recorded the estimated fair value of assets and liabilities that consisted primarily of $26.9 million of oil and gas properties and deferred tax liabilities of $8.0 million. No goodwill was recorded in connection with either of these transactions. Due to the sale of the Canadian operations in 2007, the impact of the Canadian acquisition is now reflected as discontinued operations in the Company’s consolidated financial statements.

2005 - On September 27, 2005, the Company completed the acquisition of Northrock for approximately $1.7 billion in cash. The Company purchased all of the outstanding shares of Northrock pursuant to a share purchase agreement that was entered into on July 8, 2005. As of September 27, 2005, Northrock owned approximately 292,000 net producing acres, plus approximately 950,000 net acres of undeveloped leasehold. Northrock’s activities are concentrated in Saskatchewan and Alberta with key exploration plays in Canada’s Northwest Territories, British Columbia and the Alberta Foothills. The Company acquired Northrock primarily to

strengthen its position in North American exploration and development properties. The following is a calculation and final allocation of purchase price to the acquired assets and liabilities based on their relative fair values:

CALCULATION OF PURCHASE PRICE (IN MILLIONS)
Cash paid, including transaction costs	$	1,737.5

Plus fair market value of liabilites assumed:
Other liabilites	100.5
Asset retirement obligation	38.8
Deferred income taxes	745.6
Total purchase price for assets acquired	$	2,622.4

ALLOCATION OF PURCHASE PRICE (IN MILLIONS)
Proved oil and gas properties	$	1,715.8
Unproved oil and gas properties	787.3
Other assets	119.3
Total	$	2,622.4

In addition to the Northrock acquisition, during 2005 the Company, through its Northrock subsidiary, also completed two corporate acquisitions in Canada for cash consideration totaling approximately $32.9 million and six other producing property acquisitions for cash consideration totaling approximately $51 million. The Company recorded the estimated fair value of assets and liabilities on the two corporate transactions which consisted primarily of $50 million of oil and gas properties and deferred tax liabilities of $15.8 million. No goodwill was recorded for these transactions. Due to the sale of the Canadian operations in 2007, the impact of the Canadian acquisitions is now reflected as discontinued operations in the Company’s consolidated financial statements.

2004 - In December 2004, the Company completed the acquisition of two privately held corporations for approximately $282.5 million in cash and a deferred payment of $26.4 million made in 2005 to the former owner of one of the corporations. The corporations have subsequently been named Pogo Producing (San Juan) Company and Pogo Producing (Texas Panhandle) Company (the “corporations”). The transactions included properties located primarily in the San Juan basin of New Mexico and the Texas Panhandle. The Company acquired the corporations primarily to strengthen its position in domestic natural gas properties. The Company recorded the estimated fair values of the assets acquired and the liabilities assumed at the closing date of the transactions, which primarily consisted of oil and gas properties of $423.7 million, long term debt of $50.1 million and deferred tax liabilities of $67.4 million. No goodwill was recorded for the transactions.

In 2004, the Company also completed six other producing property acquisitions for cash consideration totaling approximately $186 million.

Pro Forma Information

The following summary presents unaudited pro forma consolidated results of operations for the three years ended December 31, 2006 for the Company’s continuing operations as if the acquisitions of Latigo and the corporations had each occurred as of January 1, 2004. The pro forma results are for illustrative purposes only and include, in addition to the pre-acquisition historical results of Latigo and the corporations, adjustments such as increased depreciation, depletion and amortization expense resulting from the allocation of fair value to oil and gas properties acquired, increased interest expense on acquisition debt and the related tax effects of these adjustments. The unaudited pro forma information (presented in millions of dollars, except per share amounts) is not necessarily indicative of the operating results that would have occurred had the acquisitions been consummated at that date, nor are they necessarily indicative of future operating results.

(6) Commitments and Contingencies

The Company has commitments for operating leases (primarily for office space) in Houston, Midland, Laredo, Tulsa, Ho Chi Minh City, and New Plymouth, and for other equipment (including gas compressors). Rental expense for office space was $3.8 million in 2006, $2.7 million in 2005, and $2.9 million in 2004. Rental expense for other equipment was $5.1 million in 2006, $5.0 million in 2005 and $5.5 million in 2004.

Future minimum lease payments related to the Company’s operating leases at December 31, 2006 are approximately $14.7 million in 2007; $13.9 million in 2008; $13.8 million in 2009; $13.1 million in 2010; $12.5 million in 2011 and $86.8 million thereafter. Where rented equipment such as compressors is considered essential to the operation of the lease, the Company has assumed that such equipment will be leased for the estimated productive life of the reserves, even if the contract terminates prior to such date.

On February 23, 2007, a shareholder that owned approximately 7.9% of the Company’s stock, formally provided notice to the Company of its intention to conduct a proxy contest at the Company’s 2007 Annual Meeting that would, if successful, result in a change in a majority of the Board of Directors by (i) nominating three persons in opposition to the Board’s nominees, and (ii) proposing amendments to the Company’s bylaws to expand the Board and elect three additional nominees. Directors are elected by a plurality of vote of the shareholders, and amendments to the Company’s bylaws must be approved by a majority of the shares outstanding. If there is a change in a majority of the Board of Directors not approved by a vote of two-thirds of the incumbent directors, the indentures governing the Company’s senior subordinated notes require the Company to offer to repurchase all outstanding notes at 101% of their principal amount and to repay all outstanding senior debt, including the credit facility, prior to repurchasing the notes (or obtain consent from the lenders allowing for such repurchase). Although such a change in a majority of the Board of Directors would not, by itself, constitute an event of default under the credit facility, failure by the Company to perform its indenture obligations would allow the lenders under the credit facility to accelerate the credit facility debt. The Company does not have sufficient cash available to fund a repurchase of all or a substantial portion of the senior subordinated notes or to repay all or a substantial portion of outstanding debt under the credit facility.

Defaults under, or the acceleration of, the notes or credit facility could significantly and adversely affect the Company’s financial position. If the Company were not able to refinance the debt, it could be required to sell substantial assets in order to satisfy the obligations or to seek protection under the federal bankruptcy laws. Any refinancing of the Company’s existing debt with new debt, if available, would likely involve substantial costs, including the premium to repurchase notes from existing holders and transaction costs associated with obtaining new debt. Such new debt may be on less favorable terms than the Company’s existing debt. Refinancing may negatively impact the Company’s strategic alternatives initiative.

A change in the majority of the Board of Directors as a result of the pending proxy contest would also trigger an obligation to make payments under the Company’s executive employment agreements (upon termination of employment by the executives during specified periods or in specified circumstances) and under the Company’s severance and retention program.

(7) Severance and Retention Incentive Program

The Company has established a Change of Control Severance and Retention Program (the “Plan”), effective as of January 1, 2007, to provide severance benefits and a retention incentive to employees who are designated by the Plan Administrator as eligible for benefits under the Plan in the event of a “Change in Control.” The Company expects to pay approximately $11.4 million in retention incentives under the program during 2007.

The Company made retention incentive plan payments of $2 million to those personnel who were employed by Latigo at both May 2, 2006, the date of acquisition, and November 2, 2006, six months thereafter.

The Company had in place a retention incentive plan that covered personnel who were employed by Northrock on September 27, 2005 (the date of acquisition) and were still employed by Northrock on September 27, 2006. On that latter date, the Company made payments of $13.4 million related to the retention incentive plan. The impact of the Northrock retention plan has been reported as discontinued operations in the Company’s consolidated financial statements.

(8) Sales to Major Customers

The Company is an oil and gas exploration and production company that generally sells its oil and gas to numerous customers on a month-to-month basis. For purposes of comparison, sales have been presented for all three years for customers who have exceeded 10% of revenues in any given year (expressed in millions):

	2006		2005		2004
Shell Trading Company	$	96.4	$	116.8	$	147.1
Kinder Morgan	59.8		113.8		94.9

(9) Credit Risk

Substantially all of the Company’s accounts receivable at December 31, 2006 and 2005, result from oil and gas sales and joint interest billings to other companies in the energy industry. This concentration of customers and joint interest owners may impact the Company’s overall credit risk, either positively or negatively, in that these entities may be similarly affected by industry-wide changes in economic or other conditions. Such receivables are not collateralized. The Company provides reserves for specifically identified receivables from customers and joint interest owners that, in the opinion of management, are considered doubtful of collection. As of December 31, 2006 and 2005, the Company’s allowances for doubtful accounts were not material.

(10) Geographic Information

Subsequent to the sale of Northrock in 2007, the Company consists of one operating segment for oil and gas with operations primarily in the United States.

(11) Discontinued Operations

Under SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”, the Company classifies assets to be disposed of as held for sale or, if appropriate, discontinued operations when they have received appropriate approvals by the Company’s management or Board of Directors and when they meet other criteria.

Northrock Resources Ltd.

. On May 28, 2007, the Company entered into an agreement to sell all of the outstanding stock of its wholly-owned subsidiary, Northrock Resources Ltd. (“Northrock”) for $2.0 billion in cash. The Company completed the sale during the third quarter of 2007 and used the proceeds to pay off senior debt and invest the remainder while evaluating debt repayment strategies.

Thaipo Ltd. and B8/32 Partners Ltd.—

On August 17, 2005, the Company completed the sale of its wholly owned subsidiary Thaipo Ltd. and its 46.34% interest in B8/32 Partners Ltd. (collectively referred to as the “Thailand Entities”) for a purchase price of $820 million. The Company recognized an after tax gain of approximately $403 million on the sale of the Thailand Entities.

Pogo Hungary Ltd.—

On June 7, 2005, the Company completed the sale of its wholly owned subsidiary Pogo Hungary, Ltd. (“Pogo Hungary”) for a purchase price of $9 million. The Company recognized an after tax gain of approximately $5 million on the sale of Pogo Hungary.

Northrock, the Thailand Entities and Pogo Hungary are classified as discontinued operations in the Company’s financial statements. The summarized financial results and financial position data of the discontinued operations were as follows (amounts expressed in millions):

(12) Employee Benefit Plans

The Company has a tax-advantaged savings plan in which all U.S. salaried employees may participate. Under such plan, a participating employee may allocate up to 30% of their salary, up to a maximum allowed by law, and the Company will then match the employee’s contribution on a dollar for dollar basis up to the lesser of 6% of the employee’s salary or $15,000 in 2006. Funds contributed by the employee and the matching funds contributed by the Company are held in trust by a bank trustee in six separate funds. Amounts contributed and earnings and accretions thereon may be used to purchase shares of the Company’s common stock, invest in a money market fund or invest in four stock, bond, or blended stock and bond mutual funds according to instructions from the employee. The Company contributed $1.9 million to the savings plan in 2006, $1.5 million in 2005, and $1.4 million in 2004.

The Company has adopted a trusteed retirement plan for its U.S. salaried employees. The benefits are based on years of service and the employee’s average compensation for five consecutive years within the final ten years of service which produce the highest average compensation. The Company makes annual contributions to the plan in the amount of retirement plan cost accrued or the maximum amount that can be deducted for federal income tax purposes. During 2006 and 2005, the Company contributed $7.0 million and $4.5 million to the plan, respectively. The Company will continue to monitor the plan to determine whether a contribution will need to be made in 2007. The plan’s investment strategy and goals are to ensure, over the long-term life of the retirement plan, an adequate pool of sufficiently liquid assets to support the benefit obligations to participants, retirees and beneficiaries. Investment objectives are long-term in nature covering typical market cycles of three to five years.

Although the Company has no obligation to do so, the Company currently provides full medical benefits to its retired U.S. employees and dependents. For current employees, the Company assumes all or a portion of post-retirement medical and term life insurance costs based on the employee’s age and length of service with the Company. The post-retirement medical plan has no assets and is currently funded by the Company on a pay-as-you-go basis. The expected Company contributions to the post-retirement medical plan during 2007 are approximately $0.7 million.

The following two tables set forth the plans’ status (in millions of dollars) as of and for the years ended December 31 of the applicable year.

	Retirement		Post-Retirement
	Plan		Medical Plan
Actuarial loss	$	14.6	$	3.8
Prior service cost	0.3		0.9

Total	$	14.9	$	4.7

Prior to the adoption of SFAS 158, the Company had no minimum pension liability that would have been reflected in AOCI.

The amounts in AOCI expected to be recognized as net periodic benefit expense over the next fiscal year are as follows (in millions of dollars):

	Retirement		Post-Retirement
	Plan		Medical Plan
Actuarial loss	$	2.0	$	0.4

Rate of compensation increase	5.50	%	5.50	%	4.75	%	—		—		—

To develop the expected long-term rate of return on plan assets assumption, the Company considered the current level of expected returns on risk free investments (primarily government bonds), the historical level of the risk premium associated with the other asset classes in which the portfolio is invested and the expectations for future returns of each asset class. The expected return for each asset class was then weighted based on the target asset allocation to develop the expected long-term rate of return on plan assets assumption for the portfolio. This resulted in the selection of the 8.50% assumption for 2006.

The Company determines the discount rate used to measure plan liabilities as of the December 31 measurement date for both plans. The discount rate reflects the current rate at which the associated liabilities could be effectively settled at the end of the year. In determining this rate, the Company reviews rates of return on fixed-income investments of similar duration to the liabilities in the plan that receive high, investment grade ratings by recognized ratings agencies. Additionally, the Company performs an analysis of the Citigroup Pension Discount Curve (CPDC) as of that date for both plans. The CPDC uses spot rates that represent the equivalent yield on high quality, zero coupon bonds for specific maturities. These rates were used to develop an equivalent single discount rate based on the plans’ expected future benefit payment streams and duration of plan liabilities. Using this methodology, the Company determined a discount rate of 5.75% to be appropriate as of December 31, 2006, which is an increase of 0.25 percentage points from the rate used as of December 31, 2005.

Expected benefit payments for the retirement and the post-retirement medical plans for the next ten years are as follows (expressed in millions):

	Expected Benefit Payments
Year Ending	Retirement		Post-Retirement
December 31,	Plan		Medical Plan
2007	$	3.5	$	0.7
2008	5.3		0.8
2009	5.0		0.9
2010	4.9		1.1
2011	6.1		1.2
Next 5 Years	37.8		7.8

The following table provides the target and actual asset allocations in the retirement plan:

			Actual as of December 31,
Asset Category	Target		2006		2005
Equity securities	100	%	89	%	87	%
Debt securities	0	%	0	%	0	%
Real estate	0	%	0	%	0	%
Other	0	%	11	%	13	%
Total	100	%	100	%	100	%

For measurement purposes related to the Company’s post-retirement medical plan, a 10% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2006. The rate is assumed to decrease gradually to 5% for 2013 and remain at that level thereafter. This compares to the amounts used for 2005 measurement purposes, where a 10% annual rate of increase in the per capita cost of covered health care benefits was assumed, decreasing gradually to 5% for 2012 and remaining level thereafter.

Assumed health care cost trends have a significant effect on the amount reported for the health care plan. A one-percentage-point change in assumed health care cost trend rates would have the following effects (in millions):

	One Percentage Point
	Increase		Decrease
Effect on total of service and interest cost components for 2006	$	0.8	$	(0.7	)
Effect on year-end 2006 post-retirement benefit obligation	$	5.2	$	(4.2	)

In December 2003, the Medicare Prescription Drug Improvement and Modernization Act of 2003 (the Act) was signed into law. The Act introduced a prescription drug benefit under Medicare (Medicare Part D), as well as a nontaxable federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. The Company has elected not to reflect changes in the Act in its 2006 financial statements since the Company has concluded that the effects of the Act are not a significant event that calls for remeasurement under FAS 106.

(13) Stock-Based Compensation Plans

The Company’s incentive plans authorize awards granted wholly or partly in common stock (including rights or options which may be exercised for or settled in common stock) to key employees and non-employee directors. Awards to employees of the Company may be made as grants of stock options, stock appreciation rights, stock awards, cash awards, performance awards or any combination thereof (collectively, “Stock Awards”). Employee stock options generally become exercisable in three installments. Employee restricted stock generally vests in four installments. The number of shares of Company common stock available for future issuance was 3,284,524, 3,637,057, and 3,975,757 as of December 31, 2006, 2005, and 2004, respectively. Stock options granted during and after 2003 expire 5 years from the date of grant, if not exercised. Stock options granted prior to 2003, if not exercised, expire 10 years from the date of grant.

Effective January 1, 2003, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standards No. 123, “Accounting for Stock Based Compensation” (“SFAS 123”) and the prospective method transition provisions of Statement of Financial Accounting Standards No. 148, “Accounting for Stock Based Compensation—Transition and Disclosure—an amendment of FAS No. 123” (“SFAS 148”) for all Stock Awards granted, modified or settled after January 1, 2003. Under SFAS 123, the Company recognized compensation cost for all Stock Awards on either a straight-line basis over the vesting period or upon retirement, whichever was shorter (the nominal vesting period approach). On January 1, 2006, the Company adopted the provisions of SFAS No. 123 (revised 2004) (“SFAS 123R”), “Share-Based Payment”, which replaced the provisions of SFAS 123. The cumulative effect of the change in accounting principle resulting from the adoption of SFAS 123R was recognized in the Company’s financial statements through the elimination of previously recognized deferred compensation costs, with offsetting amounts recorded in the additional paid in capital account within shareholders’ equity and the related deferred income tax payable. The Company adopted SFAS 123R using the modified prospective transition method. Under that transition method, compensation cost recognized during the twelve months ended December 31, 2006 includes (a) compensation cost for Stock Awards granted prior to, but not yet vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS 123, and (b) compensation cost for all Stock Award grants subsequent to January 1, 2006 based on the grant date fair value estimated in accordance with SFAS 123R. Compensation cost for restricted stock and stock options is recognized using the nonsubstantive vesting period approach, i.e. (a) on a straight-line basis, over either the vesting period for the applicable Stock Award or until retirement eligibility age, whichever is shorter, or (b) over a six-month period for Stock Awards to employees who have reached retirement eligibility age. The impact of using the nonsubstantive vs. the nominal vesting period approach would have resulted in a reduction in after-tax compensation expense of $1.0 million for the year ended December 31, 2006, and an increase in after-tax compensation expense of $3.1 million and $10.0 million for the years ended December 31, 2005, and 2004, respectively.

The following table illustrates the effect on the Company’s net income and earnings per share if the fair value recognition provisions of SFAS 123R for employee stock-based compensation had been applied to all Stock Awards outstanding during the years ended December 31, 2005 and 2004 (in millions of dollars, except per share amounts):

	Year Ended

Restricted Stock

The fair value of restricted stock grants is estimated based on the average of the high and low share price on the date of grant. The Company granted the following shares of restricted stock during the periods indicated:

		Weighted
		Average
	Number	Grant Date
Year Ended	of	Fair Value
December 31,	Awards	(in millions)

2006	400,000	$	17.8

2005	351,800	$	19.5

2004	303,400	$	13.2

A summary of the status of the Company’s unvested restricted stock activity during and as of the year ended December 31, 2006, is presented below:

			Weighted
			Average
			Grant Date
Unvested restricted stock:	Shares		Fair Value

Unvested at December 31, 2005	630,600		$	51.57

Granted	400,000		$	44.49
Vested	(233,875	)	$	48.67
Forfeited	(25,700	)	$	47.83

Unvested at December 31, 2006	771,025		$	47.54

As of December 31, 2006, there was approximately $27.1 million of total unrecognized compensation cost related to unvested restricted stock that is expected to be recognized over a weighted average period of 1.5 years. Total compensation expense for restricted stock for the years ended December 31, 2006, 2005, and 2004 was $15.6 million ($9.9 million, net of tax), $7.1 million ($4.5 million, net of tax), and $3.3 million ($2.1 million, net of tax), respectively. The total fair value of shares that vested and were distributed during the years ended December 31, 2006, 2005 and 2004, was $10.7 million, $6.4 million, and $1.6 million, respectively, which resulted in the recognition of deferred tax assets in excess of the benefits of the tax deductions (“excess tax deficiencies”) of $0.3 for 2006, and the recognition of the benefits of the tax deductions in excess of deferred tax assets (“excess tax deductions”) of $0.5 million and $0.02 million for 2005 and 2004, respectively.

Stock Options

The Company granted options covering 30,000 shares of stock during the period ended December 31, 2004. Those options had a grant date fair market value of $0.3 million. No stock options were granted during 2005 or 2006. The fair value of previous stock option grants that vested in 2005 and 2006 was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions used for stock option grants made in 2004 and 2003, respectively: risk free interest rates of 3.00% and 2.30%, expected volatility of 25.7% and 28.4%, dividend yields of 0.48% and 0.61%, and an expected life of the options of three and a half and three years. Total compensation expense for stock options for the years ended December 31, 2006, 2005, and 2004 was $0.7 million ($0.5 million, net of tax), $1.4 million ($0.9 million, net of tax) and $1.4 million ($0.9 million, net of tax), respectively. The total intrinsic value of stock options exercised during the years ended December 31, 2006, 2005, and 2004 was $2.7 million, $7.3 million, and $9.4 million respectively, resulting in excess tax deductions of $1.0 million, $2.7 million, and $3.3 million for the same respective periods. As of December 31, 2006, there was less than $0.1 million in unrecognized compensation cost related to unvested stock options that is expected to be recognized over a weighted average period of 4 months. The Company’s current practice is to issue new shares to satisfy stock option exercises.

Restricted Stock Units

The Company awards Restricted Stock Units (the “Units”) to certain employees of Northrock. The Units vest ratably over a three-year period. Vested Units are payable in cash in an amount equal to the fair market value of the Company’s common stock for the five-day trading period ending on the vesting date. The Company recognizes compensation expense and a liability over the vesting period based on the average fair market value of Company common stock for the last five trading days of the period. On October 31, 2006, 43,979 of the Units vested, which resulted in payments of $2 million. As of December 31, 2006, there were 239,133 unvested Units. For the years ended December 31, 2006, and 2005, the Company recognized compensation expense related to the Units of $2.4 million and $0.4 million, respectively. Amounts related to the Units are reported in discontinued operations in the Company’s consolidated financial statements.

(14) Commodity Derivatives and Hedging Activities

During the year ended December 31, 2006, the Company recognized $2.7 million of pre-tax gains in its oil and gas revenues related to settled price hedge contracts, as well as a pre-tax gain of $3.4 million due to ineffectiveness on unsettled hedge contracts During the year ended December 31, 2005, the Company recognized $11.3 million of pre-tax losses in its oil and gas revenues from settled price hedge contracts, as well as a pre-tax loss of $1.3 million due to ineffectiveness on unsettled hedge contracts. During the year ended December 31, 2004, the Company did not recognize any gains or losses from its hedging activities related to 2004 production, but did recognize a pre-tax gain of $0.7 million due to ineffectiveness. Net unrealized gains on derivative instruments of $6.6 million, net of deferred taxes of $3.8 million, have been reflected as a component of other comprehensive income for the year ended December 31, 2006. Based on the fair market value of the hedge contracts as of December 31, 2006, the Company would reclassify additional pre-tax gains of approximately $6.2 million (approximately $3.9 million after taxes) from accumulated other comprehensive loss (shareholders’ equity) to net income during the next twelve months.

The estimated fair value of the Company’s hedging transactions is based upon various factors that include closing exchange prices on the NYMEX, volatility and the time value of options. Further details related to these hedging activities as of December 31, 2006 are as follows:

Although all of the Company’s collars are effective as economic hedges, the Gulf of Mexico disposition and the shut-in forecasted hydrocarbon production from the Company’s Gulf of Mexico properties (resulting primarily from hurricane activity during the third quarter of 2005) caused certain of the gas and crude oil collar contracts to lose their qualification for hedge accounting under SFAS 133. The Company now recognizes all future changes in the fair value of these collar contracts in the consolidated statement of income for the period in which the change occurs under the caption “Commodity derivative income (expense).’’ The Company recognized realized and unrealized gains (losses) related to these contracts of $7.3 million and ($13.6) million for the periods ended December 31, 2006, and 2005, respectively. As of December 31, 2006, the Company had the following collar contracts that no longer qualify for hedge accounting:

(15) Divestitures

On May 31, 2006, the Company sold an undivided 50 percent interest in each and all of its Gulf of Mexico oil and gas leasehold interests and related pipelines and equipment to an affiliate of Mitsui & Co., Ltd., for approximately $448.8 million, after purchase price adjustments. The sale resulted in a pre-tax gain of $302.7 million. This gain, along with $2 million of pre-tax gains on sales of other properties, has been reflected in the caption “Net (gain) loss on sales of properties” in the Company’s results of operations.

(16) Asset Retirement Obligations

The Company accounts for future abandonment costs pursuant to SFAS 143, which requires that the fair value of a liability for an asset retirement obligation be recorded in the period in which it is incurred and the corresponding cost capitalized by increasing the carrying amount of the related long-lived asset. The liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. If the liability is settled for an amount other than the recorded amount, a gain or loss is recognized.

POGO PRODUCING COMPANY & SUBSIDIARIES

STANDARDIZED MEASURE OF DISCOUNTED FUTURE

NET CASH FLOWS RELATED TO PROVED OIL AND GAS RESERVES—Unaudited

The standardized measure of discounted future net cash flows from the production of proved reserves (expressed in millions) is developed as follows:

1. Estimates are made of quantities of proved reserves and the future periods in which they are expected to be produced based on year-end economic conditions.

2. The estimated future gross revenues from proved reserves are priced on the basis of year-end market prices, except in those instances where fixed and determinable natural gas price escalations are covered by contracts.

3. The future gross revenue streams are reduced by estimated future costs to develop and to produce the proved reserves, as well as certain abandonment costs based on year-end cost estimates, and the estimated effect of future income taxes. These cost estimates are subject to some uncertainty.

4. The cash flows are discounted at 10% per annum.

The standardized measure of discounted future net cash flows does not purport to present the fair value of the Company’s oil and gas reserves. An estimate of fair value would also take into account, among other things, the recovery of reserves in excess of proved reserves, anticipated future changes in prices and costs, a discount factor more representative of the time value of money and the risks inherent in reserve estimates.
