                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Stockholders,
North Central Oil Corporation:

We have audited the accompanying consolidated balance sheets of North Central
Oil Corporation (a Delaware corporation) and subsidiaries ("North Central") as
of December 31, 2000 and 1999, and the related consolidated statements of
operations, cash flows and stockholders' equity for each of the three years in
the period ended December 31, 2000. These financial statements are the
responsibility of North Central's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the 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 includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of North Central as of December
31, 2000 and 1999, and the results of their operations and their cash flows for
each of the three years in the period ended December 31, 2000 in conformity with
accounting principles generally accepted in the United States.

As described in Note 2 of the Notes to the Consolidated Financial Statements,
North Central restated its December 31, 1999 and 1998 financial statements to
include the purchase cost attributable to the acquisition of the minority
interests by its parent, NORIC Corporation.

                 NORTH CENTRAL OIL CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   ORGANIZATION

     North Central Oil Corporation, together with its wholly-owned subsidiaries
     ("North Central"), is a privately held independent oil and gas company
     incorporated under the laws of the state of Delaware in 1955. North Central
     is wholly-owned directly and indirectly by a single entity, NORIC
     Corporation ("NORIC"). North Central is in the business of acquiring,
     exploring, developing and producing oil and gas reserves. In addition,
     North Central is the manager of certain joint venture programs and
     affiliated entities (collectively, the "Affiliates").

     In November 2000, NORIC's board of directors approved a definitive merger
     agreement whereby NORIC would be acquired by Pogo Producing Company. The
     transaction is conditioned upon, among other things, the approval of the
     stockholders of both companies and customary regulatory approvals.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of North
     Central, its wholly-owned subsidiaries and its proportionate share of the
     assets, liabilities, revenue and expenses of the Affiliates. These
     financial statements have been prepared in accordance with generally
     accepted accounting principles and all significant intercompany accounts
     and transactions have been eliminated. Additionally, certain
     reclassifications have been made to conform the prior year data to the
     current format.

     RESTATEMENT

     As discussed in Note 3, effective May 1, 1998, NORIC acquired the minority
     interests in North Central. North Central's financial statements for 1998
     and 1999 were originally issued without including the purchase cost
     attributable to the acquisition of the minority interests by NORIC. The
     accompanying financial statements for 1998 and 1999 have been restated to
     record the purchase cost attributable to the acquisition of the minority
     interests in North Central's separate financial statements. This
     restatement resulted in a reduction of net income before federal income
     taxes of $4,700,000 and $5,600,000 and a reduction of net income of
     $3,100,000 and $3,700,000 for the years ended December 31, 1999 and 1998,
     respectively.

     CASH AND CASH EQUIVALENTS

     Cash in excess of North Central's daily requirements is generally invested
     in short-term, highly liquid investments with maturities of three months or
     less. Such investments are carried at cost, which approximates market, and
     are considered to be cash equivalents.

     PROPERTY AND EQUIPMENT

     Oil and gas properties are accounted for on the successful-efforts method
     whereby costs, including lease acquisition costs, lease and well equipment
     and intangible drilling costs associated with exploration efforts which
     result in the discovery of proved reserves and costs associated with
     development efforts, whether or not successful, are capitalized. If an
     exploratory well is determined to be dry, the capitalized exploratory costs
     are charged to expense. All other exploratory costs are charged to expense
     as incurred.

     Capitalized costs of oil and gas properties are amortized on a
     property-by-property basis using the unit-of-production method based on
     units of proved reserves. In the event that the net capitalized costs of an
     oil and gas property were to exceed its undiscounted future net cash flows,
     the carrying value of such property would be reduced to its fair value
     through a charge to current operations.

   8

                 NORTH CENTRAL OIL CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     Costs of acquiring unevaluated oil and gas properties to be explored by
     North Central are capitalized and subsequently are transferred to producing
     oil and gas properties when a lease or other mineral interest becomes
     productive or are charged to expense at such time as the lease or other
     mineral interest is surrendered or determined to be unproductive.

     When assets are sold, the difference between the proceeds and the net book
     value is credited or charged to income as gain or loss.

     GAS IMBALANCES

     Gas imbalances result when joint owners of an oil and gas property take
     more or less production from the property than they are entitled to based
     on their ownership percentages in the property. North Central accounts for
     its share of such imbalances under the entitlements method whereby it
     records revenue for its share of production whether or not the gas is
     actually taken. Differences between the amounts taken and the amounts to
     which North Central is entitled are reflected as gas imbalance receivables
     or payables.

     STOCK-BASED COMPENSATION

     North Central measures the liability for its phantom share incentive
     compensation plan based on the change in the fair value of phantom shares
     granted over their respective grant price and recognizes compensation
     expense in the period in which the changes in value occur. The amounts
     accrued for this plan are reported as deferred compensation in the
     accompanying financial statements.

     INCOME TAXES

     Deferred federal income taxes are provided under the liability method on
     differences between the reported amount of an asset or liability in the
     financial statements and its tax reporting basis. Such differences arise
     primarily from the deduction for tax purposes of certain oil and gas
     exploration and development costs which are capitalized for financial
     reporting purposes.

     USE OF ESTIMATES

     The preparation of the consolidated 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, disclosure of contingent assets and liabilities, if any, at
     the date of the consolidated financial statements and reported amounts of
     revenue, costs and expenses during the reporting period.

3.   REORGANIZATION OF AFFILIATED ENTITIES

     Effective May 1, 1998, North Central merged several affiliated entities
     into North Central, exchanged stock in North Central for assets, and NORIC
     acquired the minority interests in North Central. These transactions were
     consummated simultaneously as part of a tax-free reorganization in
     accordance with Internal Revenue Code Section 351. The following discusses
     each of the transactions separately and the impact on the financial
     statements.

     MERGER OF AFFILIATED ENTITIES

     The shareholders of several affiliated entities exchanged 100% of their
     common stock for common stock of NORIC. The assets and liabilities of these
     affiliated entities were then contributed to North Central in exchange for
     shares of North Central's common stock. These transactions represented a
     reorganization of entities under common control and were accounted for
     similar to a pooling-of-interests effective as of the closing date. The
     financial reporting basis of the assets and liabilities that were combined
     with North Central's accounts as of May 1, 1998 are as follows:

     North Central issued 2,050 shares of its $1.00 par value common stock to
     the affiliated entities in connection with these mergers and recorded
     additional paid-in-capital for the excess of the net book value of the
     assets acquired over the par value of the common stock issued.

     EXCHANGE OF COMMON STOCK FOR ASSETS

     NORIC acquired certain oil and gas assets and liabilities from a Subchapter
     S corporation owned by one of North Central's stockholders in exchange for
     stock in NORIC. This transaction represented a purchase where the assets
     and liabilities acquired were recorded at their fair market values. NORIC
     then contributed the acquired assets and liabilities to North Central in
     exchange for shares of North Central's common stock. The financial
     reporting basis of the assets and liabilities contributed to North Central
     as of May 1, 1998 are as follows:

     North Central issued 3,620 shares of its $1.00 par value common stock to
     NORIC for the net assets listed above and recorded additional
     paid-in-capital for the excess of the fair market value of the net assets
     acquired over the par value of the common stock issued.

     ACQUISITION OF MINORITY INTERESTS

     NORIC exchanged 10,499 shares of its common stock for 10,499 shares of
     common stock of North Central owned by the minority interests. This
     transaction represented a purchase where the assets and liabilities
     acquired were recorded at their fair market values. The accompanying
     financial statements for 1998 and 1999 have been restated to record the
     purchase cost attributable to this acquisition in North Central's separate
     financial statements. The fair market value in excess of the net book value
     for the assets and liabilities acquired from the minority interests as of
     May 1, 1998 is as follows:

4.   TRANSACTIONS WITH RELATED PARTIES

     In the ordinary course of business, North Central incurs receivable and
     payable balances resulting from the payment of costs and expenses and
     collection of revenue on behalf of the Affiliates.

     North Central is reimbursed for certain costs incurred in managing its
     Affiliates. For the years ended December 31, 2000, 1999 and 1998, general
     and administrative expenses have been reduced by reimbursements of $15,000,
     $30,000 and $200,000, respectively.

     North Central retains the services of a law firm of which certain directors
     and former stockholders of North Central are partners. During the years
     ended December 31, 2000, 1999 and 1998, North Central recorded $300,000,
     $100,000 and $200,000, respectively, for legal services performed by such
     firm.

5.   FINANCIAL INSTRUMENTS

     HEDGES

     North Central enters into various oil and gas hedging contracts with major
     financial institutions and purchasers of oil and gas products in managing
     its exposure to product price volatility. Under such contracts, North
     Central receives or makes payments based on the differential between fixed
     and variable prices for crude oil and natural gas, which amounts are
     recorded as oil and gas sales. North Central also utilizes financial
     instruments to sell a portion of its natural gas production at New York
     Mercantile Exchange prices less a basis differential rather than the local
     area index prices. Amounts received or paid under such hedging and
     financial instrument contracts reduced oil and gas sales by $29,200,000 in
     2000, reduced oil and gas sales by $1,500,000 in 1999 and increased oil and
     gas sales by $1,500,000 in 1998. The contracts in place as of December 31,
     1999 and 1998, had market values of $6,700,000 and $3,500,000,
     respectively. As discussed below, all hedging and financial instrument
     contracts were terminated during 2000.

     The production volumes and fixed prices received for 2000, 1999 and 1998
     under North Central's various oil and gas swap contracts are summarized in
     the table below:



                                           2000               1999               1998

  Average gas price per unit ....              $2.27              $2.27              $2.38


     During 2000, North Central terminated its fixed price swap contracts for
     January 2001 through December 2003 at a cost of $30,100,000. North Central
     also terminated its basis contracts for September 2000 through December
     2001 for proceeds of $49,000. The net cost paid to terminate these
     commodity hedges were recorded as deferred charges. These deferred charges
     are amortized over the remaining terms of the original contracts.

                 NORTH CENTRAL OIL CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     North Central has also entered into interest rate swap contracts in order
     to mitigate the impact of changes in interest rates on its long-term debt.
     The notional principal amounts under such contracts prior to their
     termination discussed below, totaled approximately $80,000,000 in 2000, and
     were $81,300,000 and $58,000,000 at December 31, 1999 and 1998,
     respectively, with an effective interest rate of approximately 7%. Amounts
     received or paid under such contracts are recorded as interest expense and
     decreased such expense in 2000 by $200,000 and increased such expense in
     1999 and 1998 by $300,000 and $200,000, respectively.

     In August 2000, North Central terminated all of its interest rate swap
     contracts resulting in the receipt of $2,600,000. North Central recorded
     deferred income which is being amortized over the remaining terms of the
     original contracts.

     Interest rate swap contracts in place as of December 31, 1999 and 1998 had
     market values of $3,100,000 and ($1,400,000), respectively.

     As North Central has terminated its commodity hedges and interest rate
     swaps as discussed above, North Central does not anticipate that the
     adoption of Statement of Financial Accounting Standards No. 133 "Accounting
     for Derivative Instruments and Hedging Activities" will have a material
     impact on its financial statements.

     CONCENTRATION OF CREDIT RISK

     Financial instruments that potentially subject North Central to
     concentrations of credit risk consist primarily of cash and short-term
     investments, accounts receivable and financial instruments used in hedging
     activities. North Central generally places its cash and short-term
     investments with a single high-quality financial institution and enters
     into hedging contracts with high-quality financial institutions and major
     purchasers of oil and gas products. North Central does not believe that
     there are significant risks of nonperformance by any of these
     counterparties.

     Since North Central's joint interest partners and purchasers of North
     Central's oil and gas production are concentrated within the energy
     industry, credit risk exists with respect to accounts receivable. North
     Central controls its credit risk through credit approvals, credit limits
     and monitoring procedures. Additionally, North Central requires letters of
     credit and advance payments, if deemed necessary.

     The largest purchaser of North Central's oil and gas production (Enron
     Capital and Trade Resources Corporation) accounted for $51,400,000,
     $28,200,000, and $20,500,000 of total oil and gas sales for the years ended
     December 31, 2000, 1999 and 1998, respectively. The second largest
     purchaser of North Central's oil and gas production (Conoco, Inc. in 2000
     and NGC Oil Trading and Transportation in 1999 and 1998) accounted for
     $26,800,000, $15,600,000 and $11,700,000 of total oil and gas sales for the
     years ended December 31, 2000, 1999 and 1998, respectively. North Central's
     third largest purchaser of oil and gas production (NGC Oil Trading and
     Transportation in 2000 and Conoco, Inc. in 1999) accounted for $20,300,000
     and $13,600,000 of total oil and gas sales for the years ended December 31,
     2000 and 1999, respectively.

6.   FEDERAL INCOME TAXES

     As a result of the reorganization of affiliated entities, North Central
     became a member of a consolidated tax group with NORIC for federal income
     tax reporting purposes effective May 1, 1998. This required North Central
     to file a final income tax return for the four months ended April 30, 1998
     resulting in a tax refund of $200,000 received in 1999.

     North Central generated a tax net operating loss of $2,500,000 and a
     percentage depletion carryforward of $300,000 for the period from May 1,
     1998 to December 31, 1998. This tax loss and depletion carryforward were
     utilized in 1999 to offset federal taxable income generated in 1999. The
     carryforwards utilized in 1999 were recognized in the financial statements
     as a reduction of the deferred income tax provision for 1998 and a
     corresponding increase in the deferred income tax provision in 1999.

                                       11

                 NORTH CENTRAL OIL CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     Also in 1999, North Central filed amended federal income tax returns for
     the 1995 and 1996 tax years. The amendments were filed claiming additional
     allowable depletion deductions which resulted in a $300,000 tax refund
     received in 1999.

     At December 31, 1999, North Central had alternative minimum tax credits of
     $1,200,000 from prior years whose utilization is governed by the separate
     return limitation year rules of the Internal Revenue Code. These
     alternative minimum tax credits were utilized in 2000 to reduce North
     Central's current federal income tax provision.

     The difference between the effective rate of the provision for income taxes
     and the amount which would be determined by applying the statutory federal
     income tax rate to income before the provision for income taxes is as
     follows:



                                                                            2000              1999              1998

7.   LONG - TERM DEBT

     At December 31, 2000 and 1999, long-term debt consisted of borrowings of
     $124,500,000 and $120,000,000, respectively, under North Central's
     revolving credit facility. The carrying amounts for long-term debt
     approximate the fair value of such debt.

     In April 1999, North Central amended and restated its $140,000,000 credit
     facility increasing the available line of credit up to $175,000,000 and
     increasing the maximum margin charged over the Eurodollar rate from 1.25%
     to 1.50%. North Central used initial borrowings under the new facility to
     retire the amounts previously outstanding under its prior facility and
     finance the acquisition of producing oil and gas properties.

     North Central's $175,000,000 credit facility provides for revolving
     balances (subject to the borrowing base limitation) through November 2003,
     the maturity date, or to a later date if extended. As of December 31, 2000,
     North Central's borrowing base is $175,000,000. Pursuant to the credit
     agreement, borrowings are made using various interest rate options which
     include the Eurodollar rate plus a margin ranging from .875% to 1.50% or
     the current prime rate. At December 31, 2000 and 1999, advances totaling
     $124,500,000 and $120,000,000, respectively, were outstanding under the
     credit facility with various interest rates averaging 8.04% in 2000 and an
     interest rate of 7.8% in 1999. Subsequent to December 31, 2000, North
     Central decreased the amount of outstanding debt under its facility to
     $27,000,000, with proceeds received from Walton Corporation (a wholly-owned
     subsidiary of NORIC) under a $68,500,000 demand promissory note as
     discussed below and operating cash flows.

     The credit agreement discussed above contains various covenants that, among
     other things, set minimum net worth and interest coverage requirements, and
     limit the amount of additional indebtedness that can be incurred and the
     amount of annual dividends that can be paid. The agreement also provides
     for a semiannual borrowing base redetermination and the payment of various
     bank fees, including quarterly commitment fees.

                 NORTH CENTRAL OIL CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     The amount of available borrowing under the credit facility is reduced by
     the issuance of any letters of credit. At December 31, 2000, North Central
     had established one irrevocable standby letter of credit in the amount of
     $1,400,000 as security for the payment of certain abandonment costs. No
     amounts have been drawn under this letter of credit.

     In January 2001, North Central executed a $68,500,000 demand promissory
     note payable to Walton Corporation, a wholly-owned subsidiary of NORIC. The
     proceeds of the demand promissory note were used to retire existing
     advances on North Central's credit facility. North Central agreed to pay
     interest on the unpaid principal balance of the note at the rate of 5.75%
     per annum.

8.   EMPLOYEE BENEFIT PLANS

     North Central sponsors a number of employee benefit and compensation plans,
     of which the principal ones are discussed below. The other plans do not
     have a significant impact on the financial statements, either individually
     or in the aggregate.

     MONEY PURCHASE PENSION PLAN

     North Central's pension plan is a defined contribution plan covering
     substantially all of its employees and the employees of its subsidiaries
     who have completed 60 days of service. North Central contributes seven
     percent of each covered employee's base salary to the plan, which amounts
     are funded on a current basis and invested at the direction of the employee
     in one or more mutual funds. Contributions vest to the employee over a
     five-year period of service. Contributions made by North Central and
     charged to expense in 2000, 1999 and 1998 were $300,000 each year.

     401(k) PLAN

     North Central has a voluntary 401(k) savings plan covering substantially
     all of its employees and the employees of its subsidiaries who have
     completed 60 days of service. The plan allows eligible employees to make
     contributions of up to six percent of their salary before federal income
     taxes. North Central matches such contributions and both North Central and
     employee contributions are invested at the direction of the employee in one
     or more mutual funds. The employee vests in North Central's contributions
     over a five-year period of service. Contributions made by North Central and
     charged to expense in 2000, 1999 and 1998 were $300,000, $300,000 and
     $200,000, respectively.

     OTHER POSTRETIREMENT PLANS

     North Central sponsors unfunded postretirement benefit plans for all
     employees who retired prior to 1996. Such plans provide medical and life
     insurance benefits for retired employees on a contributory basis. The
     accrued postretirement benefit cost included in other noncurrent
     liabilities in North Central's balance sheet at December 31, 2000 and 1999
     was $1,200,000 each year. Net periodic postretirement benefit cost for the
     years ended December 31, 2000, 1999 and 1998 was ($1,000), $6,000 and
     $29,000, respectively.

     PHANTOM SHARE PLAN

     Effective January 1, 1996, North Central instituted a phantom share plan to
     provide incentive compensation to certain officers and employees of North
     Central. Under this plan, the participants are entitled to receive the
     increase in value of granted phantom shares during vesting periods that run
     through December 31, 2001 to December 31, 2003. North Central has granted
     approximately 6,600 phantom shares as of December 31, 2000, resulting in a
     liability for future compensation of $45,100,000 that was accrued as of
     December 31, 2000.

     The pending merger with Pogo Producing Company will result in immediate
     vesting of phantom shares granted under North Central's phantom share plan.
     Based on the value of the merger consideration and

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     100% vesting of granted phantom shares, North Central's liability for
     future compensation under the phantom share plan is currently estimated to
     be $51,000,000. The merger agreement provides that amounts payable under
     the phantom share plan shall be paid by North Central immediately prior to
     the closing of the merger.

9.   COMMITMENTS AND CONTINGENCIES

     LEASE OBLIGATIONS

     North Central leases office space pursuant to a lease agreement that was
     set to terminate on December 31, 2000. In June 2000, North Central renewed
     its office lease agreement and extended the primary term of the lease until
     December 31, 2001, with an option to extend the term of the lease for an
     additional year. In August 2000, North Central leased additional space for
     a primary term of 11 months. Future noncancelable payments under the office
     lease are $400,000 for 2001. Rent expense for the years ended December 31,
     2000, 1999 and 1998 was $400,000, $300,000 and $300,000, respectively.

     North Central leases compressors used in its oil and gas production
     operations. The terms of the leasing agreements provide for seven-year base
     terms, extension of the base term and purchase options available at the end
     of the leases. Future minimum rental payments are $1,000,000 each year for

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     STANDARDIZED MEASURE OF DISCOUNTED FUTURE CASH FLOWS RELATING TO PROVED OIL
     AND GAS RESERVES (UNAUDITED)

     The following presentation of the standardized measure of discounted future
     net cash flows is not intended to be a measure of the fair market value of
     North Central's oil and gas properties nor an estimate of the present value
     of actual future cash flows to be obtained as a result of their development
     and production. Instead, it is intended to provide a somewhat better means
     for comparing the value of North Central's proved reserves at a given time
     with those of other oil and gas producing companies than is provided by a
     simple comparison of raw proved reserve quantities.
