AND P&H TUBE CORPORATION REPORT ON AUDIT OF COMBINED FINANCIAL STATEMENTS FOR THE PERIOD FROM OCTOBER 1, 1997 TO FEBRUARY 28, 1998 F-1 REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors and Stockholders of Southwestern Pipe, Inc. and P&H Tube Corporation We have audited the combined balance sheet of Southwestern Pipe, Inc. and P&H Tube Corporation (the Company) as of February 28, 1998 and the related combined statements of income, changes in stockholders' equity and cash flows for the period from October 1, 1997 to February 28, 1998. 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 audit. We conducted our audit in accordance with generally accepted auditing standards. 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 audit provides a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the combined financial position of Southwestern Pipe, Inc. and P&H Tube Corporation as of February 28, 1998, and the results of their combined operations and their cash flows for the period from October 1, 1997 to February 28, 1998 in conformity with generally accepted accounting principles. As discussed in Note 3 of Notes to Combined Financial Statements, the combined financial statements as of February 28, 1998 and for the period from October 1, 1997 to February 28, 1998 have been restated.

F-6 SOUTHWESTERN PIPE, INC. AND P&H TUBE CORPORATION NOTES TO COMBINED FINANCIAL STATEMENTS, CONTINUED 1. THE ENTITIES: The combined financial statements include the accounts and operations of Southwestern Pipe, Inc. and P&H Tube Corporation which are under common control and ownership (collectively referred to as the Entities). All material intercompany transactions and balances have been eliminated in combination. Southwestern Pipe, Inc. (SPI), formerly a division of SPAX Incorporated (SPAX), is involved in the manufacturing, fabricating, and finishing of high quality tubular products through its plant in Houston, Texas. P&H Tube Corporation (P&H), also formerly a division of SPAX, is involved in the manufacturing, fabricating, and finishing of high quality tubular products through its plant in Bossier City, Louisiana. Effective May 1, 1997, SPAX completed a tax-free reorganization of its divisions into three separate corporate entities, SPI, P&H and SeaCAT Corporation (SeaCAT), which is a wholly-owned subsidiary of SPAX. The tax-free reorganization and incorporation of the divisions of SPAX at May 1, 1997 resulted in the allocation of assets and liabilities from SPAX to SPI, P&H and SeaCAT. The method of allocation was primarily based upon specific identification; however, the allocation of the current and long-term portions of the revolving line of credit was determined in a manner consistent with the equity ratios of the new entities. On March 6, 1998, SPI and P&H entered into a Stock Purchase Agreement with Northwest Pipe Company, a publicly-held company headquartered in Portland, Oregon, under which Northwest Pipe Company agreed to acquire 100% of the outstanding stock of the Entities for a purchase price of approximately $40 million, subject to adjustment. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: INVENTORIES Inventories are stated at the lower of last-in, first-out (LIFO) cost or market. The excess amount of current cost over the stated LIFO value was $442,644 at February 28, 1998. Cost of sales for the period from October 1, 1997 to February 28, 1998 would have increased by $444,922 if the first-in, first-out (FIFO) cost method had been used. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at cost. Depreciation is computed principally using the straight-line method over the estimated useful lives of the related assets. Maintenance, repairs and minor renewals are expensed as incurred. Gains or losses resulting from the sale or retirement of assets are included in income. INCOME TAXES The Entities record deferred income tax assets and liabilities based upon the difference between the financial statement and income tax bases of assets and liabilities using enacted income tax rates. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount expected to be realized. Income tax expense is the tax payable for the period and the change during the period in net deferred income tax assets and liabilities. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. F-7 SOUTHWESTERN PIPE, INC. AND P&H TUBE CORPORATION NOTES TO COMBINED FINANCIAL STATEMENTS, CONTINUED 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED: CONCENTRATIONS OF CREDIT RISK Financial instruments which potentially subject the Entities to concentrations of credit risk consist principally of trade receivables. Trade receivables are with a large number of customers, including municipalities, manufacturers, distributors and contractors, dispersed across a wide geographic base. During the period from October 1, 1997 to February 28, 1998, sales to two customers represented 36% of total P&H sales and sales to one customer represented 11% of total SPI sales. FAIR VALUE OF FINANCIAL INSTRUMENTS The fair value of financial instruments are the amounts at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The carrying amounts reflected in the combined balance sheets for cash and cash equivalents, trade receivables, other current assets and current liabilities approximate fair value because of the short maturity for these instruments. The carrying value approximates the fair value of the Entities' borrowings under its long-term arrangements based upon interest rates available for the same or similar loans. RECENT ACCOUNTING PRONOUNCEMENTS In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS No. 130, REPORTING COMPREHENSIVE INCOME, which establishes requirements for disclosure of comprehensive income. The objective of SFAS 130 is to report a measure of all changes in equity that result from transactions and economic events other than transactions with owners. Comprehensive income is the total of net income and all other non-owner changes in equity. SFAS 130 is effective for fiscal years beginning after December 15, 1997. Also in June 1997, the FASB issued SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION. This Statement will change the way public companies report information about segments of their business in their annual financial statements and requires them to report selected segment information in their quarterly reports issued to shareholders. It also requires entity-wide disclosures about the products and services an entity provides, the material countries in which it holds assets and earns revenues and its major customers. This Statement is effective for fiscal years beginning after December 15, 1997. In February of 1998, the FASB issued SFAS No. 132, EMPLOYERS' DISCLOSURE ABOUT PENSION AND OTHER POSTRETIREMENT BENEFITS. This statement revises employers' disclosures about pension and other postretirement benefit plans. It does not change the measurement or recognition of those plans. The statement suggests combined formats for presentation of pension and other postretirement benefit disclosures. The statement also permits reduced disclosures for nonpublic entities. This statement is effective for fiscal years beginning after December 15, 1997. The Entities' management has studied the implications of SFAS 130, SFAS 131 and SFAS 132 and based on the initial evaluation, expects the adoption to have no impact on the Entities' financial condition or results of operations, but will require revised disclosures when the respective statements become effective. 3. RESTATEMENT: The Company has restated the combined financial statements as of February 28, 1998 and for the period from October 1, 1997 to February 28, 1998 to (i) increase the allowance for doubtful accounts by $133,000, (ii) increase capitalized inventory costs by $179,790, (iii) reclassify $230,000 of inventory to a noncurrent asset, (iv) accrue warranty costs of $358,000 and (v) accrue additional liabilities of $71,268. These adjustments reduced retained earnings at October 1, 1997 by $222,500 and reduced net income in the period October 1, 1997 to February 28, 1998 by $16,578. F-8 SOUTHWESTERN PIPE, INC.

DEBT: SPAX has a revolving line of credit and revolving term loan agreement with Fleet Capital Corporation (Fleet Capital), collateralized by accounts receivable, inventories and equipment. Upon the reorganization described in Note 1, the agreement with Fleet Capital was amended to include SPI and P&H, in addition to SPAX. All three companies are jointly and severally liable to Fleet Capital for the amounts outstanding under the line of credit. Subject to the consummation of the Stock Purchase Agreement discussed in Note 1, the agreement with Fleet Capital was amended to release the Entities from any further obligation under the agreement. The total amount due to Fleet Capital by all entities was $9,909,319 at February 28, 1998. The interest rate defined by the agreement is a choice of either the London Interbank Offered Rate (5.6% at February 28, 1998) plus 2% or the lending institution's prime rate (8.5% at February 28, 1998) plus 0.5%. Interest expense is allocated based upon the outstanding average debt balance of the respective entity. On March 9, 1998, the portions of the revolving line of credit and the revolving term loan which relate to the Entities were paid in full as part of the agreement entered into with Northwest Pipe Company, as discussed in Note 1. The agreement contains restrictive covenants prohibiting or limiting certain actions of SPAX, SPI and P&H, including payment of cash dividends, capital expenditures, investments and incurrences of debt, and requires certain actions of the entities, including the maintenance of specified levels of profitability and tangible net worth, as defined. At February 28, 1998, the entities were not in compliance with the restrictive covenant related to capital expenditures. The lender has waived compliance with this covenant. F-9 SOUTHWESTERN PIPE, INC. AND P&H TUBE CORPORATION NOTES TO COMBINED FINANCIAL STATEMENTS, CONTINUED 7. INCOME TAXES: The provision for income taxes consisted of the following: Current: Federal $ 363,000 State 43,026 --------- 406,026 Deferred (124,926) --------- $ 281,100 --------- --------- The tax effects of temporary differences that give rise to significant portions of deferred tax assets and liabilities are presented below: Deferred tax assets: Accounts receivable $ 77,400 Inventories 28,500 Accrued employee benefits 82,900 Accrued warranty 134,200 --------- Total deferred tax assets 323,000 Deferred tax liabilities: Property, plant and equipment (52,600) --------- Net deferred tax assets $ 270,400 --------- --------- No valuation allowance has been established for deferred tax assets as management believes it is more likely than not that the deferred tax assets will be realized. 8. RELATED-PARTY TRANSACTIONS: SeaCAT provides various general and administrative services to SPI and P&H. For the period from October 1, 1997 to February 28, 1998, SPI and P&H were billed $84,000 by SeaCAT for general and administrative services. Such amounts are settled through the current portion of the revolving line of credit and are included in net selling, general and administrative expenses. 9. COMMITMENTS: SPI leases certain office equipment under the terms of a noncancelable agreement which expires in 1999. Minimum future lease payments under this operating lease as of February 28, 1998 are as follows: 1998 $ 8,947 1999 8,052 ------- $16,999 ------- ------- Rent expense for all leases with terms exceeding one year was $10,736 for the period from October 1, 1997 to February 28, 1998.

PF-3 NORTHWEST PIPE COMPANY AND SUBSIDIARIES NOTES TO PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS (DOLLAR AND SHARE AMOUNTS IN THOUSANDS) (UNAUDITED) 1. BASIS OF PRESENTATION The accompanying unaudited pro forma consolidated financial statements have been prepared to present the effect of the acquisition by Northwest Pipe Company ("the Company") of Southwestern Pipe, Inc. ("Southwestern") and P&H Tube Corporation ("P&H Tube"). The pro forma consolidated balance sheet has been prepared based upon the historical financial statements of the Company, Southwestern and P&H Tube as if the acquisitions had occurred at February 28, 1998. The pro forma consolidated statement of operations for the year ended December 31, 1997 has been prepared as if the acquisition occurred at the beginning of the period. The pro forma consolidated financial statements may not be indicative of the results of operations that actually would have occurred if the transactions had been in effect as of the beginning of the period nor do they purport to indicate the results of future operations of the Company. The pro forma consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's 1997 Annual Report on Form 10-K and the combined audited financial statements and notes thereto for Southwestern and P&H included elsewhere in this report on Form 8-K/A. Management of the Company believes that all adjustments necessary to present fairly such pro forma consolidated financial statements have been made based on the terms and structure of the acquisition transactions. 2. PRO FORMA ADJUSTMENTS a. To reflect the estimated receivable from the former shareholders of Southwestern and P&H Tube, resulting from the estimated purchase price adjustment. b. Inventories were adjusted to record the effect of a change from LIFO to FIFO inventory valuation method for Southwestern and P&H Tube. c. To adjust property to the approximate fair value on the date of acquisitions. d. To reflect goodwill related to the acquisitions. e. To record repayment of note payable to financial institution and repayment of long-term debt of Southwestern and P&H Tube, net of amounts incurred related to the acquisitions. f. To record the issuance of $40.0 million of senior notes which were issued in April 1998. Proceeds received under the senior notes were used to reduce amounts outstanding under the Company's note payable to financial institution, and accordingly, in the accompanying pro forma consolidated balance sheet, the $40.0 million is classified as long-term debt.

To reflect the elimination of common stock, additional paid-in capital and retained earnings of Southwestern and P&H Tube. h. To reflect the decrease in depreciation and amortization expense related to the adjustment of assets to the estimated fair value at the acquisition date. Depreciation is computed for a ten month period, consistent with the period presented for Southwestern and P&H Tube. i. To reflect amortization of goodwill from the acquisitions, over a period of 40 years. Goodwill amortization is computed for a ten month period, consistent with the period presented for Southwestern and P&H Tube. j. To reflect interest expense related to the additional debt resulting from the acquisition of Southwestern and P&H Tube. Interest expense is computed using the rates of interest on the $40.0 million of senior notes issued in April 1998, the proceeds of which were effectively used to pay for the acquisitions of Southwestern and P&H Tube. Of the total $40.0 million, $10.0 million bears interest at 6.63% and $30.0 million bears interest at 6.91%. Interest is computed for a ten month period, consistent with the period presented for Southwestern and P&H Tube. k. To adjust income taxes to reflect the effect of the acquisitions at the effective tax rate of the Company for 1997. PF-5
