EXPLANATORY NOTE

In this Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2009 (the September 2009 Form 10-Q),
Northwest Pipe Company is restating and updating to reflect the effects of the restatement on the previously issued condensed consolidated financial statements as of December 31, 2008 and for the three and nine months ended September 30,
2008 in Part I - Item 1, Financial Statements and Item 2, Managements Discussion and Analysis of Financial Condition and Results of Operations in both tabular and textual form as it relates to December 31,
2008 and the three and nine months ended September 30, 2008. References to the Company, we, our and us in this September 2009 Form 10-Q refer to Northwest Pipe Company together, in each case,
with our subsidiaries and any predecessor entities unless the context suggests otherwise.

Concurrent with the filing of this September 2009
Form 10-Q, we are filing our Annual Report on Form 10-K for the year ended December 31, 2009, which contains restated financial information as of December 31, 2008 and for the years ended December 31, 2008 and 2007. When we file our
quarterly reports for the periods ended March 31, 2010 and June 30, 2010, we will also restate our financial information for the three months ended March 31, 2009 and the three and six months ended June 30, 2009, respectively. We
do not plan to amend previously filed reports in connection with the restatement as we believe the expenditure of resources required to produce this information is not justified by any related benefit that would result. The financial information
that has been previously filed or otherwise reported for these periods is superseded by the information in these concurrently filed reports.

Background of the Restatement and Extended Filing Delays

The filing of this September 2009 Form 10-Q has been delayed due to, among other things, the time required for the Audit Committee of our Board of Directors (the Audit Committee) to conduct an
investigation, for us to review the issues identified in the Audit Committee investigation, and for us to restate our previously issued consolidated financial statements, data and related disclosures. As previously disclosed, the Audit Committee,
with the assistance of independent professionals retained by the Audit Committee, has conducted an investigation of certain accounting matters, including certain revenue recognition practices. In addition, at the direction of the Audit Committee, we
retained an external consulting firm to assist in performing certain related analyses of our accounting practices and previously issued consolidated financial statements.

As previously disclosed, based upon its consideration of the issues identified in the Audit Committee investigation and the related accounting analyses, and after discussions with management and our
external consultants, the Audit Committee concluded that our previously issued consolidated financial statements contained material errors and should be restated. For further detail on the financial statement impacts and the adjustments made as a
result of the restatement, please see Note 2 of the Condensed Consolidated Financial Statements in Part I - Item 1, Financial Statements of this report.

Ineffectiveness of Internal Control over Financial Reporting and Disclosure Controls and Procedures

Based upon our consideration of the issues identified in the Audit Committee investigation and our related accounting analyses, we have determined that certain material weaknesses in our internal controls
existed as of September 30, 2009. For a description of the material weaknesses in our internal control over financial reporting and our plan to remediate those material weaknesses, see Part I -Item 4, Controls and Procedures of this
report. In addition, as a result of the existence of material weaknesses in our internal controls, we have also concluded that our disclosure controls and procedures were not effective as of September 30, 2009.

NORTHWEST PIPE COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in
the United States of America (US GAAP). Certain information or footnote disclosures normally included in consolidated financial statements prepared in accordance with US GAAP have been condensed or omitted, pursuant to the rules and
regulations of the Securities and Exchange Commission. In the opinion of management, the accompanying condensed consolidated financial statements include all adjustments necessary (which are of a normal and recurring nature) for the fair statement
of the results of the interim periods presented. The accompanying condensed consolidated financial statements should be read in conjunction with the Companys audited consolidated financial statements for the year ended December 31, 2009
as presented in the Companys 2009 Annual Report on Form 10-K filed concurrently with this report.

The Condensed Consolidated Financial
Statements include the accounts of Northwest Pipe Company and its subsidiaries in which the Company exercises control as of the financial statement date. Intercompany accounts and transactions have been eliminated.

Northwest Pipe Asia Pte. Ltd. (NWPA), in which the Company exercises significant influence but does not control, is accounted for under the
equity method of accounting. During the first nine months of 2009, the Company recorded purchases of property and equipment of $940,000, net of eliminations, and rental income, included in net sales, of $54,000 from NWPA. At September 30, 2009,
intercompany balances with NWPA included a receivable of $0.6 million, primarily related to rental income, cash advances, and the provision of management services, and a payable of $1.3 million related to the purchases of the property and equipment.

2. Restatement of Condensed Consolidated Financial Statements

The Company has restated its condensed consolidated statement of operations for the three and nine months ended September 30, 2008 and its condensed consolidated statement of cash flows for the nine
months ended September 30, 2008, and its condensed consolidated balance sheet at December 31, 2008, including the cumulative impact of corrected errors for periods prior to January 1, 2008.

Descriptions of the restatement adjustments recorded are as follows:

Timing of Revenue Recognition on Steel Costs Incurred.The Audit Committee investigation and related accounting analyses initially focused primarily on issues related to the Companys
application of the cost-to-cost percentage-of-completion revenue recognition methodology (the Percentage-of-Completion Method) in its Water Transmission segment. In the course of the Audit Committee investigation and the Companys
related accounting analyses, the Company, assisted by its external consultants, conducted a detailed analysis of the procedures and judgments applied by it in its historical method of applying the Percentage-of-Completion Method. The Audit Committee
and the Company also engaged in extensive discussion of these matters with the Companys external consultants and consulted with the Office of the Chief Accountant of the Securities and Exchange Commission (the SEC). Under the
Companys historical method of applying the Percentage-of-Completion Method, the cost of steel was recognized as a project cost at the time the cost was incurred, resulting in the recognition of revenue at that time. The Company has now
determined that the cost of steel should not be recognized as a project cost when the cost is incurred but should be recognized as a project cost when the steel is introduced into the manufacturing process.

The adjustments required to correct this error delay the recognition of certain previously reported contract costs, net sales and net income, but have no
impact on the aggregate amount of net sales or gross profit from each water transmission project that will ultimately be realized by the Company. The adjustments also affect certain previously reported current asset and liability balances, including
inventory, cost and estimated earnings in excess of billings on uncompleted contracts (CEEEB) and billings in excess of costs and estimated earnings on uncompleted contracts (BECEE).

Allocation of Certain Overhead and Support Costs.After a detailed review of the procedures used in its method of allocating manufacturing
overhead variances and support costs to Water Transmission projects and Tubular Products manufacturing, and extensive discussion of these matters with the Companys external consultants, the Company determined that errors occurred in its method
of allocating manufacturing overhead variances and indirect support costs to projects in the Companys Water Transmission segment and inventory in the Tubular Products segment, as well as in related assumptions and judgments, including those
regarding total estimated Water Transmission project costs. Primarily, manufacturing overhead variances and indirect support costs were not allocated to specific water transmission projects and were not properly relieved when projects were
completed. The adjustments required to correct these errors have resulted in the reduction of net sales, gross profit, and net income and have also affected certain previously reported current asset and liability balances, including inventory, CEEEB
and BECEE.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS(Continued)

(Unaudited)





Capitalization and
Depreciation.Historically, the Company has capitalized and depreciated the costs related to certain major maintenance, improvement and renewal activities for property and equipment in its Water Transmission and Tubular Products manufacturing
facilities. After conducting an analysis of the economic lives and depreciation methods used by the Company for these capitalized costs and engaging in extensive discussion of these matters with the Companys external consultants, the Company
determined that certain equipment carrying values were overstated and that there were errors in the determination of the economic lives and residual values of certain equipment. The adjustments required to correct these errors have resulted in the
reduction of previously reported net income and of net property and equipment balances, and an increase in previously reported accumulated depreciation, depreciation expense and cost of sales.

Documentation of Contract Inception Dates.Historically, the Company began recognizing revenue on water transmission projects when, in
managements judgment, a contract had been formed with the customer and contract costs had been incurred. After a detailed review of contract documentation, the Company identified certain instances in which its documentation did not provide
persuasive evidence that all contract contingencies had been satisfied prior to revenue recognition. The adjustments required to correct these errors delay the recognition of net sales, cost of sales, gross profit and net income, but have no impact
on the aggregate amount of net sales or gross profit that will ultimately be realized by the Company on the affected water transmission projects.

Foreign Exchange.Historically, the Company did not properly account for foreign currency translation or the mark-to-market impact of derivative instruments. In addition, the effects of other
restatement adjustments also necessitated additional foreign currency translation adjustments. The adjustments required to correct this error impact the recognition of certain net sales and net income. The adjustments also affect certain previously
reported current asset and liability balances, including CEEEB and BECEE.

Other Errors and Reclassifications.Other errors were
identified in the course of the Audit Committee investigation and the related accounting analyses including: (i) an error recording costs of a business re-engineering project; (ii) an error estimating the value of a vendor claim
receivable; (iii) an error in the timing of recognizing a gain on insurance proceeds; (iv) an error in the timing of recording a customer claim payable; and (v) errors related to revenue recognition for customers that should have been
accounted for using the units of delivery percentage of completion method instead of the cost-to-cost percentage of completion revenue recognition method. In addition, certain immaterial adjustments that were not made or reflected in the previously
issued consolidated financial statements are corrected in the restated consolidated financial statements.

Certain prior year classification
errors were also corrected in conjunction with the restatement. Net income was not affected by these classification errors, included in presentation corrections below. The presentation corrections in the following condensed consolidated statements
of operations tables primarily relate to the transfer of certain selling, general and administrative costs to cost of sales and movement of foreign currency translation activity from cost of sales to net sales.



The nature of the restatement adjustments and presentation corrections and the
impact on the Companys previously reported condensed consolidated statement of operations for the three months ended September 30, 2008 are shown in the following table (in thousands, except per share data):

Long-term inventories are recorded in Other Assets. The lower of cost or market adjustment was $6.1 million at
September 30, 2009 and $1.0 million at December 31, 2008.

4. Fair Value Measurements

The Company records its financial assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to
transfer a liability, in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants at the measurement date. Effective January 1, 2009, the accounting for fair value measurements
also applies to nonrecurring nonfinancial assets and nonfinancial liabilities. The adoption of this guidance did not have a material impact on the financial statements presented herein.

The authoritative guidance establishes a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. These levels are: Level 1 (inputs are
quoted prices in active markets for identical assets or liabilities); Level 2 (inputs are other than quoted prices that are observable, either directly or indirectly through corroboration with observable market data); and Level 3 (inputs are
unobservable, with little or no market data that exists, such as internal financial forecasts). The Company is required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

5. Derivative Financial
Instruments and Hedging Activities

The Company conducts business in various foreign countries and, from time to time, settles transactions
in foreign currencies. The Company has established a program that utilizes foreign currency forward contracts to offset the risk associated with the effects of certain foreign currency exposures, typically arising from sales contracts denominated in
Canadian currency. These derivative contracts are consistent with the Companys strategy for financial risk management; however, prior to June 30, 2009, they did not meet the conditions under the authoritative guidance to qualify for hedge
accounting treatment. Beginning in the quarter ended September 30, 2009, the Company adopted cash flow hedge accounting treatment for qualifying derivative contracts entered into subsequent to June 30, 2009 under the authoritative
guidance. Instruments that do not qualify for cash flow hedge accounting treatment are re-measured at fair value on each balance sheet date and resulting gains and losses are recognized in net income. As of September 30, 2009 and
December 31, 2008, the total notional amount of the derivative contracts not designated as hedges was $10.0 million (CAD$10.7 million) and $17.0 million (CAD$20.8 million), respectively. As of September 30, 2009, the total notional amount
of the derivative contracts designated as hedges was $15.1 million (CAD$16.2 million).

For each derivative contract entered into in which the
Company seeks to obtain cash flow hedge accounting treatment, the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking the hedge transaction,
the nature of the risk being hedged, how the hedging instruments effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method of measuring ineffectiveness. This process
includes linking all derivatives to specific firm commitments or forecasted transactions and the derivatives are designated as cash flow hedges. The Company also formally assesses, both at the hedges inception and on an ongoing basis, whether
the derivative contracts that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. The effective portion of these hedged items is reflected in other comprehensive income (loss). If it is
determined that a derivative contract is not highly effective, or that it has ceased to be a highly effective hedge, the Company will be required to discontinue hedge accounting with respect to that derivative contract prospectively.

Though most Canadian forward contracts have maturities not longer than 12 months at September 30, 2009, two of the Companys contracts with a
total notional value of $3.8 million (CAD$4.1 million) have maturities greater than 12 months, with the greatest maturity being 36 months.

6. Commitments and Contingencies

Securities Litigation. On November 20, 2009, a complaint against the Company, captioned Richard v. Northwest Pipe Co. et
al., No. C09-5724 RBL, was filed in the United States District Court for the Western District of Washington. The plaintiff is allegedly a purchaser of our stock. In addition to the Company, Brian W. Dunham, the Companys former President
and CEO, and Stephanie J. Welty, the Companys current CFO, are named as defendants. The complaint alleges that defendants violated Section 10(b) of the Securities Exchange Act of 1934 by making false or misleading statements between
April 23, 2008 and November 11, 2009. Plaintiff seeks to represent a class of persons who purchased the Companys stock during the same period and seeks damages for losses caused by the alleged wrongdoing.

A similar complaint, captioned Plumbers and Pipefitters Local Union No. 630 Pension-Annuity Trust Fund v. Northwest Pipe Co. et al., No.
C09-5791 RBL, was filed against the Company in the same court on December 22, 2009. In addition to the Company, Brian W. Dunham, Stephanie J. Welty and William R. Tagmyer, the Companys current Chairman of the Board, are named as
defendants in the Plumbers complaint. In the Plumbers complaint, as in the Richardcomplaint, the plaintiff is allegedly a purchaser of the Companys stock and asserts that defendants violated Section 10(b) of the
Securities Exchange Act of 1934 by making false or misleading statements between April 23, 2008 and November 11, 2009. Plaintiff seeks to represent a class of persons who purchased the Companys stock during that period, and seeks
damages for losses caused by the alleged wrongdoing.

The Richard action and the Plumbersaction were consolidated on
February 25, 2010. Plumbers and Pipefitters Local No. 630 Pension-Annuity Trust Fund was appointed lead plaintiff in the consolidated action. Defendants and lead plaintiff subsequently agreed that defendants do not need to respond to
either of the two outstanding complaints, and that a consolidated amended complaint will be filed within 45 days of the Company having completed the filing of this September 2009 Form 10-Q and its 2009 Form 10-K with the SEC. The parties also have
stipulated to a briefing schedule for motions to dismiss to be filed after the filing of a consolidated amended complaint. The Company intends to vigorously defend itself against these claims. This securities litigation is at a very early stage and,
at this time, it is not possible to predict its outcome. Therefore, the Company has not accrued any charges related to this litigation.

On March 3, 2010, the Company
was served with a derivative complaint, captioned Ruggles v. Dunham et al., No. C10-5129 RBL, and filed in the United States District Court for the Western District of Washington. The plaintiff in this action is allegedly a current
shareholder of the Companys. The Company is a nominal defendant in this litigation. Plaintiff seeks to assert, on the Companys behalf, claims against Brian W. Dunham, Stephanie J. Welty, William R. Tagmyer, Keith R. Larson, Wayne B.
Kingsley, Richard A. Roman, Michael C. Franson and Neil R. Thornton. The asserted basis of the claims is that defendants breached fiduciary duties to the Company by causing the Company to make improper statements between April 23, 2008 and
August 7, 2009. Plaintiff seeks to recover, on the Companys behalf, damages for losses caused by the alleged wrongdoing.

The
Company and the defendants have entered into an agreement with plaintiff in the Rugglesaction. Pursuant to that agreement, neither the Company nor the defendants are required to respond to the current complaint. Plaintiffs may file an
amended complaint within 60 days of the Company having completed the filing of its September 2009 Form 10-Q and its 2009 Form 10-K with the SEC. The parties have agreed on a briefing schedule for motions to dismiss to be filed after the filing of an
amended complaint. It should also be noted that derivative claims by their nature do not seek to recover damages from us, but purport instead to seek to recover damages for the benefit of us. This litigation is at a very early stage and, at this
time, it is not possible to predict its outcome. Therefore, the Company has not accrued any charges related to this litigation.

SEC
Investigation. On March 8, 2010, the staff of the Enforcement Division of the SEC issued a formal order of investigation and a subpoena for the production of documents. The Company is cooperating with the SEC, but does not know when
the inquiry and investigation will be resolved or what, if any, actions the SEC may require as part of that resolution. Any action by the SEC or other governmental agency could result in civil or criminal sanctions against the Company and/or certain
of its current or former officers, directors and/or employees. The investigation is at a very early stage and, at this time, it is not possible to predict its outcome. Therefore, the Company has not accrued any charges related to this investigation.

Environmental Litigation. On December 1, 2000, a section of the lower Willamette River known as the Portland Harbor was included
on the National Priorities List at the request of the U.S. Environmental Protection Agency (the EPA). While the Companys Portland, Oregon manufacturing facility does not border the Willamette River, an outfall from the
facilitys storm water system drains into a neighboring propertys privately owned slip. The Company and over 100 other parties have been notified by the EPA and the Oregon Department of Environmental Quality (the ODEQ) of
potential liability under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). As of September 2010, more than 280 potentially responsible parties on and nearby the river have been asked to file information
disclosure reports with the EPA. By agreement with the EPA, the ODEQ is charged with ensuring that all upland sites have source control to prevent future contamination to the river. A remedial investigation and feasibility study of the
Portland Harbor is currently being directed by a group of potentially responsible parties known as the Lower Willamette Group (the LWG). The Company made a payment of $175,000 to the LWG in June 2007 as part of an interim settlement, and
is under no obligation to make any further payment. A draft remedial investigation report was submitted to the EPA by the LWG in the fall of 2009. The feasibility study is underway and is expected to be completed by the LWG in 2011.

In 2001, groundwater containing elevated organic compounds (VOCs) was identified in one localized area of the Companys property
furthest from the river. Assessment work in 2002 and 2003 to further characterize the groundwater is consistent with the initial conclusion that the source of the VOCs is located off of Company-owned property. On January 25, 2005, the Company
entered into a Voluntary Agreement for Remedial Investigation and Source Control Measures (Agreement) with the ODEQ. The Company is one of 84 Upland Source Control Sites working with the ODEQ on Source Control and is ranked a
medium priority. The Company performed Remedial Investigation work required under the Agreement and submitted a draft Remedial Investigation/Source Control Evaluation Report on December 30, 2005. The conclusions of the report
indicate that the VOCs found in the groundwater do not present an unacceptable risk to human or ecological receptors in the Willamette River. The report also indicates there is no evidence at this time showing a connection between detected VOCs in
groundwater and Willamette River sediments.

Also, based on the remedial investigation and reporting required under the Portland, Oregon
manufacturing facilitys National Pollutant Discharge Elimination System permit for storm water, the Company and the ODEQ have identified a possible source of small amounts of polynuclear aromatic compounds and polychlorinated biphenyls and
have periodically identified trace amounts of zinc in storm water. Storm water from the Portland, Oregon manufacturing facility site is discharged to a neighboring propertys privately owned slip, as is storm water from surrounding industrial
properties. The slip was historically used for shipbuilding and subsequently for ship breaking and metal recycling. Studies of the river sediments have revealed concentration of polynuclear aromatic compounds, polychlorinated biphenyls and zinc,
which are common constituents in urban storm water discharges. To minimize the zinc traces in its storm water, the Company painted a substantial part of the Portland facilitys roofs in 2009 at a cost of $364,000. In addition, paving
improvements were made at the Portland facility at a cost of $215,000. Total spending on environmental capital projects at the Portland facility was $603,000 in 2009. Based on National Pollutant Discharge

Elimination System storm water sampling, the painting seems to have reduced the zinc in the storm water runoff. In June 2009, under the ODEQ Agreement, the Company submitted a Final Supplemental
Work Plan to evaluate and assess soil and storm water, and further assess groundwater risk. The Company is working with the City of Portland and the ODEQ to facilitate further soil and storm water source control measures.

Concurrent with the activities of the EPA and the ODEQ, the Portland Harbor Natural Resources Trustee Council (Trustees) sent some or all of
the same parties, including the Company, a notice of intent to perform a Natural Resource Damage Assessment (NRDA) for the Portland Harbor Site to determine the nature and extent of natural resource damages under CERCLA section 107. The
Trustees for the Portland Harbor Site consist of representatives from several Northwest Indian Tribes, three federal agencies and one state agency. The Trustees act independently of the EPA and the ODEQ, but the Company expects their assessment will
be coordinated with the remedial investigation and feasibility study work underway at the Portland Harbor Site. In 2009, the Trustees completed phase one of their three-phase NRDA. Phase one of the NRDA consisted of environmental studies to
fill gaps in the information available from the EPA, and development of a framework for evaluating, quantifying and determining the extent of injuries to the natural resource and the resulting damages. Phase two of the NRDA began in 2010 and
consists largely of implementing the framework developed in phase one.

The Trustees have encouraged potentially responsible parties to
voluntarily participate in the funding of their injury assessments. In 2009, one of the Tribal Trustees (the Yakima Nation) resigned and has requested funding from the same parties to support its own assessment. The Company has not assumed any
payment obligation or liability related to either request. The extent of the Companys obligation with respect to Portland Harbor matters is not known, and no further adjustment to the consolidated financial statements has been recorded as of
September 30, 2009.

The Company operates under numerous governmental permits and licenses relating to air emissions, storm-water run-off
and other environmental matters. In September and October of 2009 the Company received several notices of violation and notices to comply from the Mohave Desert Air Quality Management District (District) for violations of permitted
particulate matter emissions limits and other violations at its Adelanto, California facility. The Company is negotiating with the District to settle these matters, and believes that resolution of these matters will not result in material adverse
effects on its business, financial condition, results of operations or cash flows.

From time to time, the Company is involved in litigation
relating to claims arising out of its operations in the normal course of its business. The Company maintains insurance coverage against potential claims in amounts that are believed to be adequate. The Company believes that it is not presently a
party to any other litigation, the outcome of which would have a material adverse effect on its business, financial condition, results of operations or cash flows.

Guarantees.The Company has entered into certain stand-by letters of credit that total $6.5 million. The stand-by letters of credit relate to customer-owned raw materials and workers
compensation insurance. See Note 13, Subsequent Events for additional information regarding guarantees.

7. Segment Information

The Companys operations are organized in two reportable segments, the Water Transmission Group and the Tubular Products Group, which
are based on the nature of the products and the manufacturing process. The Water Transmission Group manufactures large-diameter, high-pressure steel pipeline systems for use in water infrastructure applications, primarily related to drinking water
systems. These products are also used for hydroelectric power systems, wastewater systems and other applications. In addition, the Water Transmission Group makes products for industrial plant piping systems and certain structural applications. The
Tubular Products Group manufactures and markets smaller diameter, electric resistance welded steel pipe used in a wide range of applications, including energy, construction, agricultural, industrial and traffic signpost systems. These two segments
represent distinct business activities, which management evaluates based on segment gross profit. Transfers between segments in the periods presented were not material.

8. Share-based Compensation

The Company has one active stock incentive plan for employees and directors, the 2007 Stock Incentive Plan, which provides for awards of stock options to purchase shares of common stock, stock
appreciation rights, restricted and unrestricted shares of common stock, restricted stock units and performance awards. In addition, the Company has two inactive stock option plans, the 1995 Stock Option Plan for Nonemployee Directors and the
Amended 1995 Stock Incentive Plan, under which previously granted options remain outstanding.

The Company recognizes compensation cost as

|                                                                             |  |                                                     |         |   |                                      |   |       | 

Restricted stock units (RSUs) and performance stock awards (PSAs) are measured at market value on the
date of grant. RSUs are service-based awards and generally vest equally over a three-year period. PSAs are performance and service-based awards. PSAs are awarded at the end of a three-year performance period, if certain performance
objectives are met, and vest equally over a two-year period. The Company recognizes compensation expense related to the performance awards based on the probable outcome of the performance conditions.

9. Income Taxes

The Company files
income tax returns in the United States Federal jurisdiction, in a limited number of foreign jurisdictions, and in many state jurisdictions. With few exceptions, the Company is no longer subject to U.S. Federal, state, or foreign jurisdiction income
tax examinations for years before 2004.

The Company had $1.5 million and $1.4 million of unrecognized tax benefits at September 30, 2009
and December 31, 2008, respectively, which would reduce the effective tax rate in a future period if recognized. The Company has reflected the net results from the expected settlement with the U.S. tax authorities in the analyses and reasonably
expects the reserve to decrease by $1.2 million within the next twelve months due to settlements with the taxing authorities. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense.

The Company provided for income taxes at estimated effective tax rates of 36.1% and 37.3% for the three and nine months ended September 30, 2009,
and 38.0% and 38.5% for the three and nine months ended September 30, 2008.

10. Comprehensive Income (Loss)

Comprehensive income (loss) is reconciled to net income for the three and nine months ended September 30, 2009 and 2008 as follows (in thousands):

11. Earnings (Loss) per Share

Basic earnings per share are computed using the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share assumes the vesting of restricted stock units,
performance awards and in the money options, provided in each case the effect is dilutive. Due to the net loss position for the three and nine months ended September 30, 2009, no securities were included in the computation of diluted net
loss per share because the effect would be antidilutive. Incremental shares of 200,213 and 208,671 for the three and nine months ended September 30, 2008 were used in the calculations of diluted earnings per share. For the three and nine months
ended September 30, 2008, none and 10,837, respectively, of options and restricted stock units were excluded from the computation of diluted earnings per share because the effect of their inclusion would have been antidilutive.

12. Recent Accounting and Reporting Developments

In January 2010, the FASB issued authoritative guidance which requires new disclosures and clarifies existing disclosure requirements for fair value measurements. Specifically, the changes require
disclosure of transfers into and out of Level 1 and Level 2 (as defined in the accounting guidance) fair value measurements, and also require more detailed disclosure about the activity within Level 3 (as defined)
fair value measurements. This guidance is effective for interim and annual reporting periods beginning after December 15, 2009, with the exception of the disclosures about purchases, sales, issuances and settlements of Level 3 assets and
liabilities, which is effective for fiscal years beginning after December 15, 2010. As this guidance only requires expanded disclosures, the adoption will not impact the Companys consolidated financial position, results of operations or
cash flows.

In October 2009, the FASB issued amendments to the accounting and disclosure for revenue recognition for multiple element
arrangements. These amendments modify the criteria for recognizing revenue and require enhanced disclosures for multiple element-deliverable revenue arrangements. This guidance will be effective prospectively for revenue arrangements entered into or
materially modified in fiscal years beginning on or after June 15, 2010. The adoption of this guidance will not have a significant impact on the Companys consolidated financial position, results of operations or cash flows.

In June 2009, the FASB issued authoritative guidance to eliminate the exception to consolidate a qualifying special-purpose entity, change the approach
to determining the primary beneficiary of a variable interest entity and require companies to more frequently re-assess whether they must consolidate variable interest entities. Under the new guidance, the primary beneficiary of a variable interest
entity is identified qualitatively as the enterprise that has both (a) the power to direct the activities of a variable interest entity that most significantly impact the entitys economic performance, and (b) the obligation to absorb
losses of the entity that could potentially be significant to the variable interest entity or the right to receive benefits from the entity that could potentially be significant to the variable interest entity. This guidance becomes effective for
fiscal years beginning after November 15, 2009. The adoption of this guidance will not have a material impact on the Companys consolidated financial position, results of operations or cash flows.

In June 2009, the FASB issued authoritative guidance that will require more information about transfer of financial assets, including securitization
transactions, and enhanced disclosures when companies have continuing exposure to the risks related to transferred financial assets. Additionally, the new guidance eliminates the concept of a qualifying special-purpose entity. This guidance is
effective for fiscal years beginning after November 15, 2009. The adoption of this guidance will not have a material impact on the Companys consolidated financial position, results of operations or cash flows.

13. Subsequent Events

Line of
Credit Agreement, Long-Term Debt Agreement and Leases

Subsequent to September 30, 2009, the Company entered into amendments to
its Amended and Restated Credit Agreement and Amended and Restated Note Purchase and Private Shelf Agreement. A summary of the amendments is as follows:



| |  |  | Limited the availability under the Amended and Restated Credit Agreement to $110.0 million until the Company delivers to the lenders its financial
statements and Compliance Certificate for the period ended September 30, 2010, after which the availability will be limited to $117.5 million. Upon delivery of the March 31, 2011 Compliance Certificate, availability will increase to $125
million;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Set the interest rates charged on outstanding balances under the line of credit at rates related to LIBOR plus 2.50% to 4.50%, or the lending
institutions prime rate, plus 1.50% to 3.50%;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Increased the interest rates charged on outstanding balances of the long-term debt agreements by 2.00% until the Company delivers its financial
statements, related Officers Certificate for the most recent fiscal period and the Companys Consolidated Total Leverage Ratio is less than 4.50:1.00. At such time the rate will decrease by 0.25%;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Waived compliance with certain covenants in the Agreements for the year ended December 31, 2009 and the quarters ended March 31 and
June 30, 2010, and made certain changes in the definition, method of calculation and amounts of certain covenants;

| |  |  | Extended the dates by which the Company is required to deliver to the lenders audited financial statements prepared in accordance with generally
accepted accounting principles for the year ended December 31, 2009, and unaudited condensed consolidated financial statements for the quarter ended March 31, 2010 and the quarter ended June 30, 2010;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Designated the delisting of the Companys common stock from trading on the Nasdaq Stock Market as an event of default; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | Required the Company to deliver to the lenders certain cash flow forecasts and a revised financial projection model and business plan.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

Guarantees

As a result of the Companys delayed SEC filings and its previous inability to provide audited financial statements as of December 31, 2009 to its suppliers, certain suppliers requested the
Company to post standby letters of credit totaling $10.0 million as of September 30, 2010 to cover its purchase amounts.

Forward Looking Statements

This Managements Discussion and Analysis of Financial Condition and Results of Operations and other sections of this Report contain forward-looking statements within the meaning of the Securities
Litigation Reform Act of 1995 and Section 21E of the Exchange Act that are based on current expectations, estimates and projections about our business, managements beliefs, and assumptions made by management. Words such as
expects, anticipates, intends, plans, believes, seeks, estimates, forecasts, should, could, and variations of such words and
similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve risks and uncertainties that are difficult to predict. Therefore, actual outcomes and results may
differ materially from what is expressed or forecasted in such forward-looking statements as a result of a variety of important factors. While it is impossible to identify all such factors, those that could cause actual results to differ materially
from those estimated by us include changes in demand and market prices for our products, product mix, bidding activity, the timing of customer orders and deliveries, production schedules, the price and availability of raw materials, excess or
shortage of production capacity, international trade policy and regulations and other risks discussed in our 2009 Form 10-K and from time to time in our other Securities and Exchange Commission filings and reports. Such forward-looking
statements speak only as of the date on which they are made and we do not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date of this Report. If we do update or correct one or more
forward-looking statements, investors and others should not conclude that we will make additional updates or corrections with respect thereto or with respect to other forward-looking statements.

Restatement of Previously Issued Financial Statements

As previously disclosed, the Audit Committee, with the assistance of independent professionals retained by the Audit Committee, has conducted an investigation of certain accounting matters, including
certain revenue recognition practices. In addition, at the direction of the Audit Committee, we retained an external consulting firm to assist in performing certain related analyses of our accounting practices and previously issued consolidated
financial statements. Based upon its consideration of the issues identified in the Audit Committee investigation and the related accounting analyses, and after discussions with management, the Audit Committee concluded that our previously issued
consolidated financial statements contained material errors and should be restated.

Managements Discussion and Analysis of Financial
Condition and Results of Operations in both tabular and textual form as it relates to the three and nine months ended September 30, 2008 has been updated to reflect the effects of the restatement described in Note 2 of the Condensed
Consolidated Financial Statements in Part I - Item 1, Financial Statements.

Overview

Our Water Transmission Group is the leading North American manufacturer of large-diameter, high-pressure steel pipeline systems for use in water
infrastructure applications, primarily related to drinking water systems. Our products are also used for hydroelectric power systems, wastewater systems and other applications. We also make products for industrial plant piping systems and certain
structural applications. These products are produced in the following manufacturing facilities strategically located across the United States and Mexico: Portland, Oregon; Denver, Colorado; Adelanto, California; Parkersburg, West Virginia; Saginaw,
Texas; Pleasant Grove, Utah and Monterrey, Mexico. The operations of the Pleasant Grove, Utah facility were temporarily suspended in February 2009 and restarted in June 2010. We have also invested in Northwest Pipe Asia, located in Singapore.
Northwest Pipe Asia has established temporary operations in Batam, Indonesia to produce structural piling to be supplied to a construction project in Singapore. Our Water Transmission Group accounted for approximately 75% of net sales in the first
nine months of 2009.

##### Table of Contents



Our water infrastructure products are
generally sold to installation contractors, who include our products in their bids to municipal agencies or privately-owned water companies for specific projects. Within the total pipeline, our products best fit the larger-diameter, higher-pressure
applications. We believe our sales are substantially driven by spending on new water infrastructure with additional spending on water infrastructure upgrades, replacements, and repairs. Pricing of our water infrastructure products is largely
determined by the competitive environment in each regional market, and the regional markets generally operate independent of each other.

We
operate our water transmission business with a long-term time horizon. Projects are often planned for many years in advance, and are sometimes part of fifty-year build out plans. However, in the near-term, we expect strained municipal budgets will
impact the Water Transmission Group.

Our Tubular Products Group manufactures other welded steel products in three facilities: Atchison,
Kansas; Houston, Texas and Bossier City, Louisiana. We produce a range of products used in several different markets. We currently make energy pipe, standard pipe, structural pipe, and traffic signpost systems, which are sold to distributors and
used in many different applications. Our Tubular Products Groups sales volume is typically driven by energy spending, non-residential construction spending, highway spending and general economic conditions. In 2009, the tubular products
industry experienced an oversaturation of imported pipe and a collapse of natural gas prices in a very short time frame. In addition, non-residential construction declined. These factors had a severe negative impact on all of our tubular products.
We believe the greatest potential for significant sales growth in our Tubular Products Group is through our energy products. Our Tubular Products Group generated approximately 25% of net sales in the first nine months of 2009.

Purchased steel represents a substantial portion of our cost of sales, and our changes in our selling prices often correlate directly to changes in steel
costs. This correlation is the greatest in our Tubular Products Group. Tubular products margins are highly sensitive to changes in steel costs, although the amounts of margins are also influenced by the current level of demand in the
marketplace.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues
and expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates on an on-going basis. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the
circumstances. Actual results may differ from these estimates under different assumptions or conditions. A description of our critical accounting policies and related judgments and estimates that affect the preparation of our consolidated financial
statements is set forth in our Annual Report on Form 10-K for the year ended December 31, 2009, filed concurrently with this report.

Recent Accounting Pronouncements

Financial Statements in Part I  Item I of this report for a description of recent accounting pronouncements, including the expected dates of adoption and estimated effects on financial position, results of operations and cash flows.

Three Months
and Nine Months Ended September 30, 2009 Compared to Three Months and Nine Months Ended September 30, 2008

Net Sales.Net sales decreased 51.9% to $61.4 million for the third quarter of 2009 compared to $127.5 million for the third quarter of 2008, and decreased 35.1% to $213.8 million in the first nine months of 2009 from $329.5 million in the first nine
months of 2008.

Water Transmission sales decreased 42.4% to $47.0 million in the third quarter of 2009 from $81.6 million in the third
quarter of 2008 and decreased 25.4% to $161.3 million in the first nine months of 2009 from $216.2 million in the first nine months of 2008. The decline in net sales was due to a decrease in tons produced and a decrease in the selling price per ton.
Tons produced declined 13% in the third quarter of 2009 from the third quarter of 2008 and 17% in the first nine months of 2009 from the first nine months of 2008. Selling price per ton decreased 34% in the third quarter 2009 from the third quarter
2008 and 11% in the first nine months of 2009 from the first nine months of 2008. The decrease in volume was due to reduced demand for production of industrial and water transmission projects. The decrease in selling prices per ton was due to more
aggressive bidding activity in 2009 resulting from reduced demand, as well as a decline in steel prices. Lower steel costs generally lead to lower contract values. Steel prices are discussed further in the gross profit analysis. Bidding activity,
backlog and sales resulting from the award of new projects, or the production of current projects, may vary significantly from period to period.

Tubular Products sales decreased 68.7% to $14.4 million in the third quarter of 2009 from $45.9 million in the third quarter of 2008 and decreased 53.6% from $113.3 million in the first nine months of
2008 to $52.5 million in the first nine months of 2009. The sales decrease was due to a decrease in tons sold and a decline in selling price per ton as all tubular product lines were negatively impacted in 2009. The most significant reductions in
demand were the result of decreases in natural gas drilling operations and lower residential and commercial construction activity. Approximately 93.0% of the total decrease in net sales in the third quarter of 2009 from the third quarter of 2008 was
attributable to our three largest product lines, with energy pipe, standard pipe and structural pipe product lines comprising 60%, 20% and 13% of the decrease, respectively. We sold 89% fewer tons of energy pipe products and our selling price per
ton decreased 47% in the third quarter of 2009 compared to the third quarter of 2008. Standard pipe sales volumes decreased 37% and our selling price per ton decreased 38% in the third quarter of 2009 as compared to the third quarter of 2008. Our
structural pipe net sales decline was due to a 51% decrease in selling price per ton, which was partially offset by a 2% increase in volume in the third quarter of 2009 as compared to the third quarter of 2008.

Approximately 94.0% of the total
decrease in Tubular Products net sales in the first nine months of 2009 from the first nine months of 2008 was attributable to our three largest product lines, with energy pipe, standard pipe and structural pipe product lines comprising 42%, 36% and
16% of the decrease, respectively. Our energy pipe net sales decline was due to a 79% volume decrease, which was partially offset by a 28% increase in selling price per ton in the first nine months of 2009 as compared to the first nine months of
2008. Standard pipe sales volumes decreased 54% and our selling price per ton decreased 19% in the first nine months of 2009 as compared to the same period in 2008. Our structural pipe sales volume decreased 23% and the selling price per ton
declined 22% in the first nine months of 2009 as compared to the first nine months of 2008.

During the three and nine months ended
September 30, 2009 and the nine months ended September 30, 2008, no single customer accounted for 10% or more of net sales. During the three months ended September 30, 2008, one customer accounted for 10.2% of net sales.

Gross Profit.Gross profit (loss) decreased 108.8% to a loss of $2.3 million (-3.7% of total net sales) in the third quarter of 2009 from
$25.8 million (20.2% of total net sales) in the third quarter of 2008 and decreased 85.4% from $58.7 million (17.8% of total net sales) in the first nine months of 2008 to $8.6 million (4.0% of total net sales) in the first nine months of 2009.

Water Transmission gross profit decreased $14.2 million, or 97.1%, to $0.4 million (0.9% of segment net sales) in the third quarter of 2009
from $14.6 million (17.9% of segment net sales) in the third quarter of 2008 and decreased $22.2 million, or 62.7%, from $35.4 million (16.4% of segment net sales) in the first nine months of 2008 to $13.2 million (8.2% of segment net sales) in the
first nine months of 2009. The drop in gross profit from the prior year was due to more aggressive bidding activity leading to lower selling prices per ton, as well as a reduction in tons produced in 2009 as compared to 2008. In addition, we
incurred fixed production costs which we were unable to absorb due to the decreased total project volume of approximately 13% in the third quarter of 2009 as compared to the prior year and approximately 17% in the first nine months of 2009 as
compared to the same period in 2008.

Our Water Transmission materials cost decreased in the third quarter of 2009 by approximately 38% from
the third quarter of 2008 due to a decline of approximately 28% in our materials cost per ton including steel. In the first nine months of 2009, our water transmission materials cost declined approximately 24% from the same period in 2008 due to a
9% decline in our materials cost per ton including steel and the decreased volumes discussed above. Our inventory values for Water Transmission products reflect a lower of cost or market expense of $3.2 million in the third quarter of 2009; $4.1
million was reserved as of September 30, 2009. We anticipate gross margins to remain at reduced levels through 2010, as the lower-margin projects awarded in 2009 flow through the income statement in subsequent periods.

Gross profit (loss) from Tubular Products decreased 124.1% to a loss of $2.7 million (-18.7% of segment net sales) in the third quarter of 2009 from
$11.2 million (24.3% of segment net sales) in the third quarter of 2008 and decreased 119.9% to a loss of $4.6 million (-8.8% of segment net sales) in the first nine months of 2009 from a profit of $23.3 million (20.6% of segment net sales) in the
first nine months of 2008. As noted above, demand for our tubular products decreased significantly, particularly for our energy products which sustained a 94% reduction in sales in the third quarter of 2009 as compared to the prior year and a
reduction of 73% in sales in the first nine months of 2009 as compared to the same period in 2008. The significant decrease in volume contributed to the loss in the third quarter of 2009 and first nine months of 2009, as the market conditions led to
reduced production and our inability to fully cover our fixed costs. This was partially offset by decreased steel costs per ton of 49% in the third quarter of 2009 compared to the third quarter of 2008 and decreased steel costs per ton of 30% in the
first nine months of 2009 compared to the same period in 2008. In addition, our inventory values for Tubular products reflect a lower of cost or market expense of $2.0 million in the third quarter of 2009; $2.1 million was reserved as of
September 30, 2009. Unlike our Water Transmission segment, contracts for our tubular products are able to be fulfilled in a relatively short time frame, typically within one to three months. Therefore, price changes are usually more quickly
reflected in sales prices and gross profit of our Tubular Products segment.

Selling, General and Administrative Expenses.Selling, general and administrative expenses decreased to $5.2 million (8.4% of total net sales) in the third quarter of 2009 from $7.1 million (5.6% of total net sales) in the third quarter of 2008 and decreased to $14.5 million (6.8% of
total net sales) in the first nine months of 2009 from $20.3 million (6.2% of total net sales) in the first nine months of 2008. The decrease of $1.9 million in the third quarter of 2009 as compared to the prior year consisted primarily of a
decrease of $0.7 million in wages and bonus expense as a result of weaker financial performance, a decrease of $0.3 million in commission expense, and a decrease of approximately $0.6 million in professional fees, travel and entertainment and other
administration expenses as a result of cost containment measures. The decrease of $5.8 million in the first nine months of 2009 as compared to the first nine months of 2008 was due primarily to a decrease of $1.5 million in wages and bonus expense
as a result of weaker financial performance, a decrease of $0.5 million in commission expense, a decrease of $0.6 million related to retirements of assets, and a decrease of approximately $2.2 million in professional fees, travel and entertainment,
outside services and other administration expenses as a result of cost containment measures.

Interest Expense.Interest expense
decreased to $1.1 million in the third quarter of 2009 from $1.3 million in the third quarter of 2008 and decreased to $3.6 million in the first nine months of 2009 from $4.5 million in the first nine months of 2008. The decrease in the expense
compared to the same periods last year was a result of lower average borrowings at a lower average interest rate.

Income Taxes. Our
effective tax rate was 36.1% and 37.3% for the three and nine months ended September 30, 2009, respectively, compared to effective tax rates of 38.0% and 38.5%, respectively, for the same periods last year.

Liquidity and Capital Resources

Sources and Uses of Cash

Our principal sources of liquidity generally include operating
cash flow and our bank credit agreement. Our principal uses of liquidity generally include capital expenditures, working capital and debt service. Information regarding our cash flows for the nine months ended September 30, 2009 is presented in
our condensed consolidated statements of cash flows contained in this September 2009 Form 10-Q, and is further discussed below.

As of
September 30, 2009, our working capital (current assets minus current liabilities) was $136.2 million as compared to $192.4 million as of December 31, 2008.

Net cash provided by operating activities in the first nine months of 2009 was $62.4 million. This was primarily the result of fluctuations in our working capital accounts, which result from timing
differences between production, shipment and invoicing of our products, as well as changes in levels of production and costs of materials. We typically have a relatively large investment in working capital, as we are generally obligated to pay for
goods and services early in the project while cash is not received until much later in the project. Our revenues in the water transmission segment are recognized on a percentage-of-completion method; therefore, there is little correlation between
revenue and cash receipts and the elapsed time can be significant. As such, our payment cycle is a significantly shorter interval than our collection cycle, although the effect of this difference in the cycles may vary from period to period.

Net cash used in investing activities in the first nine months of 2009 was $18.2 million, primarily due to capital expenditures of $18.0
million. The most significant capital projects incurring costs in the nine month period were the installation of a new mill in our California facility, and the preparation and installation of manufacturing equipment in the facility in Bossier City,
Louisiana.

Net cash used in financing activities in the first nine months of 2009 was $44.2 million, which resulted primarily from net
payments under the notes payable to financial institutions and the long term debt of $53.6 million and $4.3 million, respectively, which was partially offset by borrowings under capital lease obligations of $14.8 million.

We anticipate that our existing cash and cash equivalents, and amounts available under our credit agreement will be adequate to fund our working capital
and capital requirements for at least the next twelve months. We also expect to continue to rely on cash generated from operations and other sources of available funds to make required principal payments under our long term debt during 2010. To the
extent necessary, we may also satisfy capital requirements through additional bank borrowings, senior notes, term notes, capital and operating leases, convertible notes and equity offerings, if such resources are available. We have from time to time
evaluated and continue to evaluate opportunities for acquisitions and expansion. Any such transaction, if consummated, may use a portion of our working capital or necessitate additional bank borrowings, other forms of debt or an equity offering.

Line of Credit and Long-Term Debt

We had the following significant components of debt at September 30, 2009: a $150.0 million Credit Agreement, under which $28.5 million was outstanding; $10.7 million of Series A Term Note, $7.5
million of Series B Term Notes, $8.5 million of Series C Term Notes and $3.9 million of Series D Term Notes.

The Credit Agreement expires on
May 31, 2012, and bears interest at rates related to LIBOR plus 1.25% to 2.25%, or the lending institutions prime rate, plus 0.00% to 0.75%. Borrowings under the Credit Agreement are collateralized by substantially all of our personal
property.

At September 30, 2009, we had $28.5 million outstanding under the Credit Agreement bearing interest at a weighted average rate
of 2.37%. At September 30, 2009, we had an additional net borrowing capacity under the credit facility of $115.0 million.

The Series A
Term Note in the principal amount of $10.7 million matures on February 25, 2014 and requires annual payments in the amount of $2.1 million plus interest of 8.75% paid quarterly on February 25, May 25, August 25 and
November 25. The Series B Term Notes in the principal amount of $7.5 million mature on June 21, 2014 and require annual payments in the amount of $1.5 million plus interest of 8.47% paid quarterly on
March 21, June 21, September 21 and December 21. The Series C Term Notes in the



24

##### Table of Contents

principal amount of $8.5 million mature on October 26, 2014 and require annual payments of $1.4 million plus interest of 7.36% paid quarterly on
January 26, April 26, July 26 and October 26. The Series D Term Notes in the principal amount of $3.9 million mature on January 24, 2015 and require annual payments in the amount of $645,000 plus interest of 7.32%
paid quarterly on January 24, April 24, July 24 and October 24. The Series A Term Note, the Series B Term Notes, the Series C Term Notes, and the Series D Term Notes (together, the Term Notes) are
collateralized by accounts receivable, inventory and certain equipment.

We had $27.7 million of capital leases outstanding at
September 30, 2009, under which certain equipment used in the manufacturing process is leased. The average interest rate on the capital leases is 5.9%.

Our capital lease outstanding as of September 30, 2009 consisted of an agreement entered into as of September 2009 to finance our Bossier City, Louisiana facility (the Financing
Arrangement). As part of the Financing Arrangement, a $10 million escrow account was provided for the Company by a local government entity through a financial institution and will be released upon qualifying purchase requisitions. As we
purchase equipment for the facility, we enter into a sale-leaseback transaction with the governmental entity as part of the Financing Arrangement. As of September 30, 2009, $10.0 million was held in the escrow account, which is included in
other assets, as a result of proceeds from the Financing Arrangement. The Financing Arrangement requires us to meet certain loan covenants, measured at the end of each fiscal quarter. These loan covenants follow the covenants required by our credit
agreement.

The Credit Agreement, the Term Notes and certain of our capital leases place various restrictions on our ability to, among other
things; incur certain additional indebtedness, create liens or other encumbrances on assets, and incur additional capital expenditures. The Credit Agreement, Term Notes, and certain of our capital leases require us to be in compliance with certain
financial covenants. Our 2009 operating results led us to commence discussions in the fourth quarter of 2009 with our bank creditors to obtain waivers of our financial covenants as of December 31, 2009, March 31, 2010 and
June 30, 2010. As a result of these discussions, covenant waivers were obtained and we entered into amendments to our Amended and Restated Credit Agreement and Amended and Restated Note Purchase and Private Shelf Agreement as described in Note
13, Subsequent Events in Part I - Item 1, Financial Statements.

The amendments changed the definition, method of
application and amounts of the covenants related to the Consolidated Fixed Charge Coverage Ratio, Consolidated Senior Leverage Ratio, Consolidated Total Leverage Ratio, Consolidated Tangible Net Worth, Asset Coverage Ratio, Minimum Consolidated
EBITDA, and Maximum Consolidated Rental and Operating Lease Expense. As we were granted waivers of our financial covenants as of December 31, 2009, March 31, 2010 and June 30, 2010, these amended financial covenants will be
calculated as of September 30, 2010. Based on our business plan and forecasts of operations, we believe we will remain in compliance with our amended covenants in 2010.

Off Balance Sheet Arrangements

We do not have any off balance sheet arrangements that are reasonably likely to have a current or future material effect on our financial position, results of operations or cash flows.

Audit Committee Investigation and Restatement

As previously disclosed in public filings, the Audit Committee, with the assistance of independent professionals retained by the Audit Committee, conducted an investigation of certain accounting matters,
including certain revenue recognition practices. In addition, at the direction of the Audit Committee, an external consulting firm was retained to assist in performing certain related analyses of our accounting practices and previously issued
consolidated financial statements.

##### Table of Contents

Based upon consideration of the issues identified in the Audit Committee investigation and the related
accounting analyses, and after discussions with management, the Audit Committee concluded that our previously issued consolidated financial statements contained material errors and should be restated. We also identified material weaknesses in
internal control over financial reporting for such periods.

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are designed to provide
reasonable assurance that information required to be disclosed in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such
information is accumulated and communicated to our management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosures.

In connection with the preparation of this September 2009 Form 10-Q, our management, under the supervision and with the participation of our CEO and CFO, evaluated the effectiveness of the design and
operation of our disclosure controls and procedures as of September 30, 2009. As described below, management has identified material weaknesses in our internal controls over financial reporting, which is an integral component of our disclosure
controls and procedures. As a result of those material weaknesses, our CEO and CFO have concluded that, as of September 30, 2009, our disclosure controls and procedures were not effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended September 30, 2009 that materially affected or are reasonably likely to materially affect our internal
control over financial reporting. However, as described below under Plans for Remediation of Material Weaknesses, we have subsequently dedicated significant resources to support our efforts to improve the control environment and to
remedy the control weaknesses described herein.

Material Weakness in Internal Control over Financial Reporting

In connection with managements assessment of our internal control over financial reporting described in our 2009 Form 10-K,
management has identified the following deficiencies that constituted individually, or in the aggregate, material weaknesses in our internal control over financial reporting as of September 30, 2009:



| |  |  | We did not maintain an effective control environment, which is necessary for effective internal control over financial reporting, as evidenced by:
(i) an insufficient number of personnel with an appropriate level of GAAP knowledge and experience or ongoing training in the application of GAAP commensurate with the Companys financial reporting requirements, and (ii) insufficient
number of personnel appropriately qualified to perform an appropriately detailed review of the accounting for nonroutine transactions, which resulted in erroneous or unsupported judgments regarding the proper application of GAAP. This control
environment weakness also contributed to the additional material weaknesses described below.

| |  |  | We did not have effective controls to ensure regular validation of management assumptions used in certain of our accounting estimates. Specifically,
the Company did not have sufficient controls in place to ensure that the assumptions included in our method of allocating manufacturing overhead variances and indirect support costs to projects in our Water Transmission segment were properly
supported by underlying verifiable data.

The material weaknesses described above resulted in misstatements of the aforementioned accounts and disclosures
that resulted in a material misstatement in our annual or interim consolidated financial statements.

Plans for
Remediation of Material Weaknesses

Our Board, the Audit Committee and management are adding resources and developing and implementing
new processes and procedures to remediate, among other things, the material weaknesses that existed in our internal control over financial reporting, and our disclosure controls and procedures, as of September 30, 2009.

Subsequent to August 31, 2010, we are developing a remediation plan (the Remediation Plan) to address the material weaknesses for each
of the affected areas presented above. The Remediation Plan will ensure that each area affected by a material control weakness is put through a comprehensive remediation process. The Remediation Plan entails a thorough analysis which includes
the following phases:



| |  |  | Define and assess each control deficiency: ensure a thorough understanding of the as is state, process owners, and procedural or
technological gaps causing the deficiency. This work is underway for all identified areas;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Design and evaluate a remediation action for each control deficiency for each affected area: validate or improve the related policy and procedures;
evaluate skills of the process owners with regards to the policy and adjust as required. The Remediation Plan will require an assessment of all control failures; we expect that many of the recent improvements will provide an appropriate starting
point for the specific action plans;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Implement specific remediation actions: train process owners, allow time for process adoption and adequate transaction volume for next steps;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | Test and measure the design and effectiveness of the remediation actions; test and provide feedback on the design and operating effectiveness of the
controls; and,
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Management review and acceptance of completion of the remediation effort.
| | - |  | -------------------------------------------------------------------------

Additionally, we are evaluating and enhancing our entity level controls as part of our Remediation Plan. The following are steps we have taken in this process:



| |  |  | In March 2010, our Board of Directors appointed a new Chief Executive Officer, and in August 2010, we hired a Director of Compliance and Controls to
direct our remediation efforts.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In August 2010, our Board of Directors elected a new, independent member to join the Board of Directors.
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | We have implemented a new sub-certification process with our management group in order to demonstrate a clear commitment to corporate integrity and
compliance and a duty to report financial irregularities.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We have undertaken an effort to enhance existing and adopt new, written policies and procedures; specifically, we have focused on our cost-to-cost
percentage-of-completion revenue recognition method to describe more clearly our guiding principles related to the accounting for our Water Transmission contracts.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Remediation Plan will be administered by our Director of Compliance and Controls and will involve key leaders from across the organization, including the CEO and CFO. Each specific area of action
within the Remediation Plan will be assigned an owner who will coordinate the resources required for timely completion of the remediation activities. The Director of Compliance and Controls will report quarterly and as needed to the Audit Committee
of our Board of Directors on the progress made toward completion of the Remediation Plan.

We believe the steps taken to date have improved
the effectiveness of our internal control over financial reporting, however we have not completed the corrective processes and procedures identified herein. Accordingly, as we continue to monitor the effectiveness of our internal control over
financial reporting in the areas affected by the material weaknesses described above, we will perform additional procedures prescribed by management including the use of manual mitigating control procedures and employ any additional tools and
resources deemed necessary to ensure that our financial statements continue to be fairly stated in all material respects.
