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. The financial information as of December 31, 2009 is derived from the audited
consolidated financial statements presented in the Northwest Pipe Company (the Company) Annual Report on Form 10-K for the year ended December 31, 2009. Certain information or footnote disclosures normally included in consolidated
financial statements prepared in accordance with accounting principles generally accepted in the United States of America 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.

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 2010, the Company recorded purchases of property
and equipment of $1.5 million, net of eliminations, and rental income, included in net sales, of $0.2 million from NWPA. At September 30, 2010, intercompany balances with NWPA included a receivable of $0.7 million, primarily related to rental
income, cash advances and the provision of management services, and a payable of $0.4 million related to the purchases of the property and equipment.

Operating results for the three and nine months ended September 30, 2010 are not necessarily indicative of the results that may be expected for the entire fiscal year ending December 31, 2010.

|3. | 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.

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.

|4. | Derivative 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, 2010 and December 31, 2009, the total notional amount of the derivative contracts not designated as hedges was $1.3 million
(CAD$1.4 million) and $5.4 million (CAD$5.7 million), respectively. As of September 30, 2010 and December 31, 2009, the total notional amount of the derivative contracts designated as hedges was $13.4 million (CAD$13.9 million) and $16.2
million (CAD$17.0 million), respectively.

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 designating the derivatives 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 fair values or 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, 2010, two of the Companys contracts at that
date with a total notional value of $6.3 million (CAD$6.5 million) have maturities greater than 12 months, with the greatest maturity being 24 months.

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 the Companys stock. In addition to the Company, Brian W. Dunham, the Companys former President
and CEO, and Stephanie J. Welty, our 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 its Quarterly Report on Form 10-Q for the quarter ended September 30, 2009 (the September 30, 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 an 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

##### Table of Contents

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, 2010.

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 $18.7 million at September 30, 2010. The
stand-by letters of credit relate to workers compensation insurance and certain suppliers.



|6. | 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.

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.



|8. | 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 income tax examinations for
years before 2004.

The Company had $0.2 million of unrecognized tax benefits at September 30, 2010 and December 31, 2009 which
would reduce the effective tax rate in a future period if recognized. The Company does not believe it is reasonably possible the total amounts of unrecognized tax benefits will change significantly in the following twelve months; however, actual
results could differ from those currently expected.

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 49.8% and 40.7% for the three and nine month periods ended September 30, 2010, respectively, and estimated effective tax benefit rates of 36.1% and
37.3%, respectively, for the three and nine month periods ended September 30, 2009.

|10. | 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. Incremental shares of 19,490 and 53,369 for the three and nine months ended September 30, 2010, respectively, were used in the calculations of diluted earnings per share. Share-based awards of 75,403 and
33,049, respectively, were excluded from the computation of diluted earnings per share for the three and nine months ended September 30, 2010 because the effect of their inclusion would be antidilutive. Due to the net loss position for the
three and nine months ended September 30, 2009, share-based awards of 134,002 and 141,133, respectively, were excluded from the computation of diluted net loss per share because the effect of their inclusion would be antidilutive.



|11. | 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 is not expected to have a significant impact on the Companys consolidated financial position, results of operations or cash flows.

Item 2. Managements Discussion and Analysis of Financial Condition and Results of Operations

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.

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 58% of net sales in the first
nine months of 2010.

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 42% of net sales in the first nine months of 2010.

Purchased steel represents a substantial portion of our cost of sales, and changes in our selling prices often correlate directly to changes in steel costs. This correlation is the greatest in our Tubular
Products Group. Gross profit in our tubular products group is highly sensitive to changes in steel costs, although the current level of demand in the marketplace and its impact on selling prices also impacts gross profit.

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. As discussed in our Form 10-Q for the quarter ended June 30, 2010, we performed an interim goodwill impairment analysis as of June 30, 2010 and determined no impairment had occurred. A
description of all other 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.

Recent Accounting Pronouncements

increased 83.7% to $112.8 million for the third quarter of 2010 compared to $61.4 million for the third quarter of 2009 and increased 35.3% to $289.3 million in the first nine months of 2010 from $213.8 million in the first nine months of 2009. No
single customer accounted for 10% or more of total net sales in the third quarter of 2009, the first nine months of 2010, or the first nine months of 2009. Two customers, one in the Water Transmission segment and one in the Tubular Products segment,
accounted for 11.5% and 11.9%, respectively, of total net sales in the third quarter of 2010.

Water Transmission sales increased by 26.2% to
$59.3 million in the third quarter of 2010 from $47.0 million in the third quarter of 2009 and increased 4.2% to $168.1 in the first nine months of 2010 from $161.3 million in the first nine months of 2009. The increase in sales in the third quarter
of 2010 compared to the third quarter of 2009 was due to a 17% increase in selling prices per ton and an 8% increase in volume. The increase in sales the first nine months of 2010 as compared to the first nine months of 2009 was due to a 17%
increase in volume which was partially offset by an 11% decrease in selling prices per ton. The decrease in selling prices per ton in the first nine months of 2010 was due to a competitive bidding environment and a decline in steel prices. Lower
steel costs generally lead to lower contract values. Steel prices are discussed further in the gross profit analysis below. The increase in volume resulted from improved orders. Bidding activity, backlog and production levels may vary significantly
from period to period affecting sales volumes.

Tubular Products sales increased 271.7% to $53.4 million in the third quarter of 2010 from
$14.4 million in the third quarter of 2009 and increased 130.8% to $121.2 million in the first nine months of 2010 from $52.5 million in the first nine months of 2009. The sales increase in the third quarter of 2010 as compared to the third quarter
of 2009 was due to a 228% increase in tons sold and a 13% increase in selling price per ton. The sales increase in the first nine months of 2010 compared to the same period in 2009 was due to a 148% increase in volume which was partially offset by a
7% decrease in selling prices per ton. The most significant increase in demand was the result of increases in natural gas drilling operations, with energy pipe representing 95% and 93% of the total Tubular Product volume increase in the third
quarter and first nine months of 2010, respectively. While demand increased, selling prices per ton decreased as the volume of imported energy pipe increased early in 2010. As import duties imposed by the U.S. government took effect in 2010, the
volume of imported energy pipe decreased in the second and third quarters of 2010, which caused sales prices per ton to rise. We sold very little energy pipe in the third quarter and the first nine months of 2009, and the significant volumes in 2010
led to a 2,453% increase in energy pipe tons sold in the third quarter of 2010 as compared to the third quarter of 2009. Energy pipe tons sold also increased substantially in the first nine months of 2010 compared to the same period in 2009 with a
1,142% increase. Selling prices per ton on energy pipe increased 24% in the third quarter of 2010 compared to the third quarter of 2009, and decreased 36% in the first nine months of 2010 compared to the same period in 2009.

Gross profit. Gross
profit increased 605.6% to $11.5 million (10.2% of total net sales) in the third quarter of 2010 from a loss of $2.3 million (-3.7% of total net sales) in the third quarter of 2009 and increased 207.5% to $26.3 million (9.1% of total net sales) in
the first nine months of 2010 from $8.6 million (4.0% of total net sales) in the first nine months of 2009.

Water Transmission gross profit
increased $6.8 million, or 1,616%, to $7.2 million (12.2% of segment net sales) in the third quarter of 2010 from $0.4 million (0.9% of segment net sales) in the third quarter of 2009 and $5.7 million, or 43.2%, to $18.9 million (11.2% of segment
net sales) in the first nine months of 2010 from $13.2 million (8.2% of segment net sales) in the first nine months of 2009. Our gross profit was impacted by the higher sales discussed above and fluctuations in materials cost per ton, including
steel. Our Water Transmission materials cost per ton increased by 11% in the third quarter of 2010 compared to the third quarter of 2009, and decreased 5% in the first nine months of 2010 compared to the first nine months of 2009. In the third
quarter of 2010, Water Transmission gross profit includes a nonrecurring decrease in our health care costs of $0.6 million. In addition, the increase in gross profit from the prior year was partly due to the impacts of an inventory lower of cost or
market adjustment, which increased by $3.2 million in the third quarter of 2009 compared to a nominal change in the third quarter of 2010. The lower of cost or market adjustment increased $3.1 million in the first nine months of 2009 compared to a
decrease of $0.4 million in the first nine months of 2010.

Gross profit from Tubular Products increased to $4.2 million (7.9% of segment net
sales) in the third quarter of 2010 from a loss of $2.7 million (-18.7% of segment net sales) in the third quarter of 2009 and increased to $7.4 million (6.1% of segment net sales) in the first nine months of 2010 from a loss of $4.6 million (-8.8%
of segment net sales) in the first nine months of 2009. As noted above, demand for our tubular products increased significantly, particularly for our energy products which had minimal sales revenue of $1.1 million in the third quarter of 2009 and
increased 3,057% to $36.0 million in the third quarter of 2010 and increased to $70.5 million in the first nine months of 2010 from $8.8 million in the same period of 2009. The significant increase in volume contributed to the increase in gross
profit in 2010, as the market conditions led to higher production which allowed us to recover more of our fixed costs than in the same periods in 2009. The increased margins were partially offset by higher steel costs per ton of 21% in the third
quarter of 2010 compared to the third quarter of 2009 and 13% in the first nine months of 2010 compared to the first nine months of 2009. The increase in gross profit from the prior year was also impacted by our inventory lower of cost or market
adjustment, which increased by $2.0 million in the third quarter of 2009 compared to a $0.6 million decrease in the third quarter of 2010. The lower of cost or market adjustment increased $2.0 million in the first nine months of 2009 compared to a
decrease of $0.6 million in the first nine months of 2010.

Selling, general and administrative expenses. Selling, general and
administrative expenses increased to $8.0 million (7.1% of total net sales) in the third quarter of 2010 from $5.2 million (8.4% of total net sales) in the third quarter of 2009 and increased to $21.3 million (7.3% of total net sales) in the first
nine months of 2010 from $14.5 million (6.8% of total net sales) in the first nine months of 2009. In the third quarter of 2010 as compared to the third quarter of 2009, professional fees increased $2.1 million, primarily associated with the
investigation of certain accounting matters. In addition, tubular products sales commission expense increased $0.5 million with the increase in tubular products sales volume and annual wage increases added another $0.4 million. In the first nine
months of 2010 as compared to the first nine months of 2009, professional fees increased $5.3 million, primarily associated with the investigation of certain accounting matters. In addition, tubular products sales commission expense increased $1.0
million with the increase in tubular products sales volume, and annual wage increases added another $0.6 million.

Interest
expense. Interest expense was $2.2 million in the third quarter of 2010 and $1.1 million in the third quarter of 2009 and $5.5 million in the first nine months of 2010 and $3.6 million in the first nine months of 2009. Higher average
borrowings and higher average interest rates increased interest expense in the third quarter of 2010 compared to the third quarter of 2009. Although average borrowings were approximately the same in the first nine months of 2010 and 2009, higher
average interest rates led to increased interest expense.

Income Taxes.The tax provision was $0.7 million in the third quarter
of 2010, which reflects an effective tax rate of 49.8%, which exceeds our statutory rate of 35% due primarily to state taxes and the relationship of permanent income tax deductions and tax credits to estimated pre-tax income for the year
2010. The tax provision was $0.2 million for the first nine months of 2010 (an effective tax rate of 40.7%). When pre-tax earnings move between loss and income positions, the effective income tax rate can change significantly depending on the
relationship of permanent income tax deductions and tax credits to estimated pre-tax income or loss. Accordingly, the comparison of effective rates between periods is not meaningful in those situations.

The tax benefit for the third quarter of 2009 was $3.1 million (an effective tax rate of 36.1%), while the year to date 2009 tax benefit was $3.2 million
(an effective tax rate of 37.3%).

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, 2010 is presented in our condensed consolidated statements of cash flows contained in this September Form 10-Q, and is further discussed below.

As of September 30, 2010, our working capital (current assets minus current liabilities) was $169.2 million as compared to $122.3 million as of
December 31, 2009.

Net cash used in operating activities in the first nine months of 2010 was $35.5 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 2010 was $16.5 million, primarily for capital expenditures. The most significant capital project incurring costs in the first nine months of 2010 was the preparation of the facility in Bossier City, Louisiana to manufacture oil
country tubular goods.

Net cash provided by financing activities in the first nine months of 2010 was $52.0 million, which resulted primarily
from net borrowings of $57.1 million under our Credit Agreement, partially offset by long-term debt payments of $4.3 million.

We anticipate
that our existing cash and cash equivalents, cash flows expected to be generated by operations, and amounts available under our credit agreements 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, subordinated debt, and capital and operating leases, if such resources are available on satisfactory terms. See the discussion below under Line of Credit and Long-Term
Debt for a discussion of recent developments regarding compliance with the terms of our line of credit and long-term debt agreements. We have from time to time evaluated and continue to evaluate opportunities for acquisitions and expansion.
Any such transactions, if consummated, may use a portion of our working capital or necessitate additional bank borrowings or other sources of funding.

Line of Credit and Long-Term Debt

We had the following significant components of
debt at September 30, 2010: a $125.0 million Credit Agreement, under which $76.5 million was outstanding; $8.6 million of Series A Term Note, $6.0 million of Series B Term Notes, $7.1 million of Series C Term Notes and $3.2 million of Series D
Term Notes.

The Credit Agreement expires on May 31, 2012, and bears interest at rates related to LIBOR plus 2.50% to 4.50%, or the
lending institutions prime rate, plus 1.50% to 3.50%. Borrowings under the Credit Agreement are collateralized by substantially all of our personal property.

During the first 10 months of 2010, we entered into amendments to our Amended and Restated Credit Agreement (Credit Agreement) and Amended and Restated Note Purchase and Private Shelf
Agreement (Note Purchase Agreement). The amendments, among other things, reduced the aggregate availability of our Credit Agreement to $110 million in June 2010 from $150 million at December 31, 2009, increased interest rates
charged on outstanding balances and waived compliance with certain covenants in the Agreements for the year ended December 31, 2009 and the quarters ended March 31, 2010 and June 30, 2010. Once the Company delivers to the lenders its
financial statements and Compliance Certificate for the period ended September 30, 2010, the availability will increase to $117.5 million. Upon delivery of the March 31, 2011 Compliance Certificate, amounts available under our Credit
Agreement will increase to $125 million. In addition, the amendments changed the definitions, method of application and amounts of certain covenants. At September 30, 2010, we had $76.5 million outstanding under the Credit Agreement bearing
interest at a weighted average rate of 5.40%. At September 30, 2010, we had an additional net borrowing capacity under the credit facility of $14.8 million.

The Series A Term Note in the
principal amount of $8.6 million matures on February 25, 2014 and requires annual payments in the amount of $2.1 million plus interest of 10.50% paid quarterly on February 25, May 25, August 25 and November 25. The
Series B Term Notes in the principal amount of $6.0 million mature on June 21, 2014 and require annual payments in the amount of $1.5 million plus interest of 10.22% paid quarterly on March 21, June 21, September 21 and
December 21. The Series C Term Notes in the principal amount of $7.1 million mature on October 26, 2014 and require annual payments of $1.4 million plus interest of 9.11% paid quarterly on
January 26, April 26, July 26 and October 26. The Series D Term Notes in the principal amount of $3.2 million mature on January 24, 2015 and require annual payments in the amount of $645,000 plus interest of 9.07%
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 $8.9 million of capital leases outstanding at
September 30, 2010, under which certain equipment used in the manufacturing process is leased. The average interest rate on the capital leases is 5.72%.

Our capital lease outstanding as of September 30, 2010 includes 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 funds are 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, 2010, $2.7 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 Note Purchase Agreement and certain of our 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, Note Purchase Agreement, and certain of our 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 Credit Agreement and Note Purchase Agreement.

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. The results of our financial covenants as of September 30, 2010 are below.



| |  |  | The Consolidated Senior Leverage Ratio must not be greater than 12.75:1.0. Our ratio as of September 30, 2010 is 6.36:1.0.
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | The Consolidated Total Leverage Ratio must not be greater than 12.75:1.0. Our ratio as of September 30, 2010 is 6.36:1.0.
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | The Consolidated Tangible Net Worth must be greater than $193.3 million. Our tangible net worth as of September 30, 2010 is $225.7 million.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Asset Coverage Ratio cannot be less than 1.0:1.0. Our ratio as of September 30, 2010 is 1.7:1.0.
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | The Minimum Consolidated EBITDA cannot be less than $3.6 million for the quarter ended September 30, 2010. Our Consolidated EBITDA is $7.1
million.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------

In accordance with the requirements, the Maximum Consolidated Rental and Operating Lease Expense will next be
calculated as of December 31, 2010 and the Consolidated Fixed Charge Coverage Ratio will next be calculated as of June 30, 2011. 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.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

For a discussion of the Companys market risk associated with foreign currencies and interest rates, see Item 7A, Quantitative and
Qualitative Disclosures about Market Risk in Part II of the Companys Annual Report on Form 10-K for the year ended December 31, 2009. For the nine months ended September 30, 2010, there has been no material change in market
risk factors.

Item 4. Controls and Procedures

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.

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 2010
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, 2010. 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, 2010, 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, 2010 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.

Managements Report on 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, 2010:



| |  |  | 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.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We did not have effective controls to ensure that the Company maintained complete and accurate business documentation to support certain revenue,
property and equipment, foreign exchange and vendor claim transactions, including related assumptions and estimates.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents



| |  |  | We did not have effective controls over certain accounting system calculations in response to changes in assumptions regarding property and equipment
and other items. Specifically, the Company did not have sufficient controls in place to properly identify and validate the changes in assumptions underlying the calculations.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We did not have effective controls over certain spreadsheets. Specifically, the Company did not have sufficient review procedures in place to ensure an
accurate preparation of spreadsheets used to support the calculation of steel inventory value and standard to actual cost adjustments within the Tubular Products segment.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We did not have effective controls over our cash flow statements. Specifically, we did not have proper preparation and review procedures in place to
ensure an accurate preparation of our consolidated statements of cash flows as required by GAAP.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We did not maintain effective controls to ensure timely internal notification of business transactions and decisions requiring accounting entries.
Specifically, our sales and human resources teams and plant personnel did not communicate to our accounting staff all of the information necessary to make accurate accounting determinations for certain accounts receivable and accrued liability
balances.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The material weaknesses described above resulted in misstatements of the aforementioned accounts and disclosures
that resulted in a material misstatement in our previously issued annual and 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, 2010.

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.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents



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.
