PART I



|Item 1. | Business
|------- | --------

We are a 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 pipeline systems are also used for hydroelectric power systems, wastewater systems
and other applications. With a history that dates back more than 100 years, we have established a leading position based on a strong, widely recognized reputation for quality and service and an extensive array of product offerings. Our manufacturing
facilities are strategically located throughout North America to provide us with broad geographic coverage of our target markets, giving us competitive advantages in serving our customers.

We manufacture water infrastructure products through our Water Transmission Group, which in 2008 generated approximately 62% of our net sales. We market
our water infrastructure products through an in-house sales force comprised of sales representatives, engineers and support personnel who work closely with public water agencies, contractors and engineering firms, often years in advance of projects
being bid. This allows us to identify and evaluate planned projects at early stages and participate in the engineering and design process to promote the advantages of our systems. Our sales have historically been driven by the need for new water
infrastructure, which is based primarily on overall population growth and population movement between regions. We believe the need for new water infrastructure will continue to be a significant growth driver for us and, importantly, will be
accompanied by the increasing need for water infrastructure upgrades, repairs and replacements due to the aging and outdated water infrastructure systems throughout North America.

In addition to manufacturing water infrastructure products, we also manufacture other welded steel products through our Tubular Products Group, which in
2008 generated approximately 38% of our net sales. Our Tubular Products Group has the capability to manufacture a broad array of small-diameter, electric resistance welded (ERW) steel pipe for use in a wide range of applications,
including energy, construction, agricultural, industrial, and traffic signpost systems.

Our Industries

Water Transmission. The U.S. market for water delivery equipment and systems is estimated to be approximately $13 billion annually.
Within this market, we focus on engineered pipeline systems that utilize large-diameter, high-pressure steel pipe. In addition to these water infrastructure applications, our Water Transmission Group manufactures products for certain structural
piling applications and in-plant pipeline systems for power plants and other industrial applications. We believe the current addressable market for the products sold by our Water Transmission Group will total approximately $3 billion over the next
three years. Our core market is the large-diameter, high-pressure portion of the pipeline that is typically at the upper end of a pipeline system. This is the portion of the overall water pipeline that generally transports water from the
source to a treatment plant or from a treatment plant into the distribution system, rather than the small lines that deliver water directly into households.

A combination of population growth, movement to new population centers, dwindling supplies from developed water sources, substantial underinvestment in water infrastructure over the past several decades, and an
increasingly stringent regulatory environment are driving considerable and growing demand for water infrastructure projects in the United States. These trends are increasing the need for new water infrastructure as well as the need to upgrade,
repair and replace existing water infrastructure, which we believe will significantly increase the demand for our water infrastructure products and other products related to water transmission and distribution.

The primary drivers of growth in new water infrastructure installation are population growth and movement. According to the U.S. Census Bureau, the
population of the United States will increase by over 100 million people between 2010 and 2050. The resulting increase in demand will require substantial new infrastructure, as

##### Table of Contents

the existing U.S. water infrastructure is not equipped to provide water to millions of new residents. The combination of population growth and movement is
projected to result in more than 70 million new residents in the southern and western regions of the United States. In addition, many current water supply sources are in danger of being exhausted. The development of new sources of water at
greater distances from population centers will drive the demand for new water transmission lines. Our manufacturing facilities are well located to take advantage of the anticipated growth and demand in these regions.

Many authorities, including the U.S. Environmental Protection Agency (EPA), believe the U.S. water infrastructure is in critical need of an
update. With the average age of water transmission pipes in the United States approximately 70 years, much of the U.S. water infrastructure is antiquated and requires upgrade, repair or replacement. Some water transmission pipelines in the United
States are over 100 years old, and the American Society of Civil Engineers has given poor ratings to many aspects of the U.S. water infrastructure in their 2009 Report Card for Americas Infrastructure. By 2020, approximately 44% of the water
pipe in the United States will be classified as poor to life-elapsed if renewal or replacement of the existing infrastructure does not occur. In its third national assessment of public water system infrastructure, the EPA in
2005 estimated that a total investment of approximately $277 billion will be needed to install, upgrade and replace infrastructure over the next 20 years. The EPA estimates that approximately $184 billion of this needed investment applies to the
rehabilitation or replacement of deteriorated or undersized water transmission and distribution infrastructure.

Increased public awareness
of problems with the quality of drinking water and efficient water usage has resulted in more stringent application of federal and state environmental regulations. The need to comply with these regulations in an environment of heightened public
awareness towards water issues is expected to contribute significantly to growth in the water infrastructure industry over the next several years. Water systems will need to be installed, upgraded and replaced in order to satisfy these water quality
laws and regulations while overall demand for water continues to increase.

Tubular Products.The tubular products industry
encompasses a wide variety of products serving a diverse group of end markets. We have been active in several of these markets, including mechanical tubing, agriculture, energy, traffic signpost systems, fire protection sprinkler systems and
structural tubing. Within our focus markets, we believe traffic signpost systems, energy products, fire protection sprinkler systems and agricultural products offer significant growth opportunities. Our sales to the energy market have grown
substantially in the past few years, and we believe this market will continue to provide growth opportunities going forward. We are relocating a pipe mill from our Portland, Oregon facility to Bossier City, Louisiana in order to expand our
production of products for the energy market. We manufacture several different signpost systems and believe this business will also grow over the next several years as our systems are adopted in additional states and jurisdictions.

Products

Water Transmission Products. Water transmission pipe is used for high-pressure applications, typically requiring pipe to withstand pressures in excess of 150 pounds per square inch. Most of our water
transmission products are made to custom specifications and are for fully engineered, large diameter, high-pressure water infrastructure systems. Other uses include pipe for piling and hydroelectric projects, wastewater transmission, treatment
plants and other applications. Our primary manufacturing process has the capability to manufacture water transmission pipe in diameters ranging from 4.5 inches to 156 inches with wall thickness of 0.135 inches to 1.00 inches. We also have the
ability to manufacture even larger and heavier pipe with other processes. We can coat and/or line these products with cement mortar, polyethylene tape, polyurethane, paints, epoxies, Pritec®, and coal tar enamel according to our customers specifications. We maintain fabrication facilities that provide installation contractors with custom fabricated sections as well as straight pipe sections. We
typically deliver a complete pipeline system to the installation contractor.

Tubular Products. Our tubular products range in size from 0.50 inches to 16 inches in
diameter with wall thickness from 0.035 inches to 0.315 inches. These products are typically sold to distributors or OEMs and are used for a wide variety of applications, including water well casing, fire protection, energy, traffic signpost
systems, and agricultural products.

Marketing

Water Transmission. The primary customers for water transmission products are installation contractors for projects funded by public water agencies. Our plant locations in Oregon, Colorado, California, West Virginia, Texas,
Utah and Mexico allow us to efficiently serve customers throughout the United States, as well as Canada and Mexico. Our water transmission marketing strategy emphasizes early identification of potential water projects, promotion of specifications
consistent with our capabilities and close contact with the project designers and owners throughout the design phase. Our in-house sales force is comprised of sales representatives, engineers and support personnel who work closely with public water
agencies, contractors and engineering firms, often years in advance of projects being bid. This allows us to not only identify and evaluate planned projects at early stages, but also to participate in the engineering and design process and
ultimately promote the advantages of our systems. After an agency completes a design, they publicize the upcoming bid for a water transmission project. We then obtain detailed plans and develop our estimate for the pipe portion of the project. We
typically bid to installation contractors who include our bid in their proposals to public water agencies. A public water agency generally awards the entire project to the contractor with the lowest responsive bid.

Tubular Products.Our tubular products are marketed through a network of direct sales force personnel, sales agents, and independent
distributors in the United States, Canada and Mexico. Our tubular product facilities are located in Kansas, Texas, and Louisiana. Our marketing strategy focuses on quality, customer service and customer relationships. For example, we are willing to
sell in small lot sizes and are able to provide mixed truckloads of finished products to our customers. Our tubular products are primarily sold to distributors, although we also sell to OEMs to a lesser extent. Our sales effort emphasizes regular
personal contact with current and potential customers. We supplement this effort with targeted advertising and brochures and participation in trade shows.

Manufacturing

Water Transmission.Water transmission
manufacturing begins with the preparation of engineered drawings of each unique piece of pipe in a project. These drawings are prepared on our proprietary computer-aided design system and are used as blueprints for the manufacture of the pipe. After
the drawings are completed and approved, manufacturing begins by feeding steel coil continuously at a specified angle into a spiral weld mill which cold forms the band into a tubular configuration with a spiral seam. Automated arc welders,
positioned on both the inside and the outside of the tube, are used to weld the seam. The welded tube is then cut at the specified length. After completion of the forming and welding phases, the finished cylinder is tested and inspected in
accordance with project specifications, which may include 100% radiographic analysis of the weld seam. The cylinders are then coated and lined as specified. Possible coatings include coal tar enamel, polyethylene tape, polyurethane paint, epoxies,
Pritec® and cement mortar. Linings may be cement mortar, polyurethane or epoxies. Following coating and lining, certain pieces may be custom fabricated as required for the project. This
process is performed in our fabrication facilities. Upon final inspection, the pipe is prepared for shipment. We ship our products to project sites principally by truck and rail.

Tubular Products. Tubular products are manufactured by an ERW process in diameters ranging from 0.50 inches to 16 inches. This process
begins by unrolling and slitting steel coils into narrower bands sized to the circumference of the finished product. Each band is re-coiled and fed into the material handling equipment at the front end of the ERW mill and fed through a series of
rolls that cold-form it into a tubular configuration. The resultant tube is welded by high-frequency electric resistance welders. Some products are reconfigured into rectangular and square shapes and then cut into the appropriate lengths. After
exiting the mill, the products are straightened, inspected, tested and end-finished. Certain products are coated.

Technology.Advances in technology help us produce high quality products at competitive
prices. We continue to invest in technological improvements, which include the addition of a state of the art pipe blasting and coating facility, and two new spiral weld mills, which will provide faster speeds, utilize larger and wider coils, and
increase yield. In addition, we have installed a new water based coating system that has set the standard for the fire protection pipe market. To stay current with technological developments in the United States and abroad, we participate in trade
shows, industry associations, research projects and vendor trials of new products.

Quality Assurance. We have quality
management systems in place that assure we consistently provide products that meet or exceed customer and applicable regulatory requirements. The Quality Assurance department reports directly to the chief executive officer. All of our quality
management systems in the United States are registered by the International Organization for Standardization, or ISO, under a multi-site registration. In addition to ISO qualification, the American Institute of Steel Construction, American Petroleum
Institute, American Society for Mechanical Engineers, Factory Mutual, National Sanitary Foundation, and Underwriters Laboratory have certified us for specific products or operations. The Quality Assurance department is responsible for monitoring and
measuring characteristics of the product. Inspection capabilities include, but are not limited to, visual, dimensional, liquid penetrant, magnetic particle, hydrostatic, ultrasonic, phased array ultrasonics, real-time imaging enhancement, real-time
radioscopic, base material tensile, yield and elongation, sand sieve analysis, coal-tar penetration, concrete compression, lining and coating dry film thickness, adhesion, absorption, guided bend, charpy impact, hardness, metallurgical examinations,
chemical analysis, spectrographic analysis and finished product final inspection. Product is not released for shipment to our customers until there is verification that all product requirements have been met.

Product Liability. The manufacturing and use of our products involves a variety of risks. Certain losses may result, or be alleged to
result, from defects in our products, thereby subjecting us to claims for damages, including consequential damages. We warrant our products to be free of certain defects for one year. We maintain insurance coverage against potential product
liability claims in the amount of $51 million, which we believe to be adequate. However, there can be no assurance that product liability claims exceeding our insurance coverage will not be experienced in the future or that we will be able to
maintain such insurance with adequate coverage.

Backlog

Our backlog includes confirmed orders, including the balance of projects in process, and projects for which we have been notified we are the successful bidder even though a binding agreement has not been executed.
Projects for which a binding contract has not been executed could be canceled. Binding orders received by us may also be subject to cancellation or postponement; however, cancellation would generally obligate the customer to pay the costs incurred
by us. As of December 31, 2008 and 2007, our backlog of orders was approximately $190 million and $211 million, respectively. Backlog as of December 31, 2008 includes projects having a value of approximately $5 million for which binding
contracts had not yet been executed as of March 10, 2009. Backlog as of any particular date may not be indicative of actual operating results for any fiscal period. There can be no assurance that any amount of backlog ultimately will be
realized.

Competition

Water
Transmission. We have several competitors in the water transmission business. Most water transmission projects are competitively bid and price competition is vigorous. Price competition may reduce the gross margin on sales, which may
adversely affect overall profitability. Other competitive factors include timely delivery, ability to meet customized specifications and high freight costs which may limit the ability of manufacturers located in other market areas to compete with
us. With water transmission manufacturing facilities in Oregon, Colorado, California, West Virginia, Texas, Utah and Mexico, we believe we can more effectively compete throughout the United States, Canada and Mexico. Our primary competitor in the
water transmission

business in the western United States and southwestern Canada is Ameron International, Inc. East of the Rocky Mountains, our primary competition includes:
American Cast Iron Pipe Company and Mueller Water Products, both of which manufacture ductile iron pipe; American Spiral Weld Pipe Company, which manufactures spiral welded steel pipe; and Hanson Pipe & Precast, which manufactures concrete
pressure pipe and spiral welded steel pipe.

No assurance can be given that other new or existing competitors will not establish new
facilities or expand capacity within our market areas. New or expanded facilities or new competitors could have a material adverse effect on our ability to capture market share and maintain product pricing.

Tubular Products.The market for tubular products is highly fragmented and diversified with over 100 manufacturers in the United States and
a number of foreign-based manufacturers that export such pipe into the United States. Manufacturers compete with one another primarily on the basis of price, established business relationships, customer service and delivery. In some of the sectors
within the tubular products industry, competition may be less vigorous due to the existence of a relatively small number of companies with the capabilities to manufacture certain products. In particular, we operate in a variety of different markets
that require pipe with lighter wall thickness in relation to diameter than many of our competitors can manufacture. In our markets, we typically compete with Valmont Industries, Inc., Lindsay Manufacturing Co., Tenaris, U.S. Steel, Allied Tube and
Conduit Corp. and John Maneely Company, as well as foreign competitors.

Raw Materials and Supplies

We purchase hot rolled and galvanized steel coil from both domestic and foreign steel mills. Domestic suppliers include California Steel Industries, Inc.,
Beta Steel Corp., ArcelorMittal, Nucor Corporation, Gallatin Steel Company, Steel Dynamics, Inc., SSAB, SeverStal, and U.S. Steel Corporation. Foreign suppliers include BlueScope Steel and Ternium. We order steel according to our business forecasts
for our Tubular Products business. Steel for the Water Transmission business is normally purchased only after a project has been awarded to us. From time to time, we may purchase additional steel when it is available at favorable prices. Purchased
steel represents a substantial portion of our cost of sales. The steel industry is highly cyclical in nature and steel prices are influenced by numerous factors beyond our control, including general economic conditions, availability of raw
materials, energy costs, import duties, other trade restrictions and currency exchange rates.

We also rely on certain suppliers of coating
materials, lining materials and certain custom fabricated items. We have at least two suppliers for most of our raw materials. We believe our relationships with our suppliers are positive and have no indication that we will experience shortages of
raw materials or components essential to our production processes or that we will be forced to seek alternative sources of supply. Any shortages of raw materials may result in production delays and costs, which could have a material adverse effect
on our financial position, results of operations or cash flows.

Environmental and Occupational Safety and Health Regulation

We are subject to federal, state, local and foreign environmental and occupational safety and health laws and regulations, violation of which could lead
to fines, penalties, other civil sanctions or criminal sanctions. These environmental laws and regulations govern emissions to air; discharges to water (including stormwater); and the generation, handling, storage, transportation, treatment and
disposal of waste materials. We are also subject to environmental laws requiring the investigation and cleanup of environmental contamination at properties we presently own or operate and at third-party disposal or treatment facilities to which
these sites send or arrange to send hazardous waste. For example, we have been identified as a potentially responsible party at the Portland Harbor Site discussed under Legal Proceedings below. We believe we are in material compliance
with these laws and regulations and do not currently believe that future compliance with such laws and regulations will have a material adverse effect on our financial position, results of operations or cash flows.

##### Table of Contents

Based on our assessment of potential liability, we have no reserves for environmental investigations and
cleanup. However, estimating liabilities for environmental investigations and cleanup is complex and dependent upon a number of factors beyond our control and which may change dramatically. Accordingly, although we believe maintaining no reserve is
appropriate based on current information, we cannot assure you that our future environmental investigation and cleanup costs and liabilities will not result in a material expense. During 2008, we did not make any material capital expenditures
relating primarily to environmental compliance.

We could be subject to various enforcement matters with federal, state, local and foreign
regulators regarding our compliance with environmental and occupational safety and health laws and regulations. We are not aware of any current material enforcement matters.

We operate under numerous governmental permits and licenses relating to air emissions, stormwater run-off and other matters. We are not aware of any
current material violations or citations relating to any of these permits or licenses. We have a practice of reducing consumption of hazardous materials in our operations by substituting non-hazardous materials when possible.

Employees

As of December 31, 2008, we had 1,217
full-time employees. Approximately 26% were salaried and approximately 74% were employed on an hourly basis. A union represents all of the hourly employees at our Monterrey, Mexico facility. All other employees are non-union. We consider our
relations with our employees to be good.

|Item 1A. | Risk Factors
|-------- | ------------

Following are the key risk factors
that have affected our net sales and net income in the past and could materially impact our future net sales and net income:

The success
of our business is affected by general economic conditions, and our business may be adversely affected by an economic slowdown or recession.Periods of economic slowdown or recession in the United States, or the public perception that one may
occur, could decrease the demand for our products, affect the price of our products and adversely impact our business. We have been impacted in the past by the general slowing of the economy, and the current economic slowdown could have an adverse
impact on our business, financial position, results of operations or cash flows. In particular, our tubular products group is exposed to the non-residential construction, agriculture, energy exploration, and highway spending markets, and a
significant downturn in any one of these markets could cause a reduction in our revenues that could be difficult to offset.

##### Table of Contents

A downturn in government spending related to public water transmission projects would adversely affect
our business.Our water transmission business accounted for approximately 62% of our net sales in 2008. Our water transmission business is primarily dependent upon spending on public water transmission projects, including water infrastructure
upgrades, repairs and replacement and new water infrastructure spending, which, in turn, depends on, among other things:



| |  |  | the need for new or replacement infrastructure;
| | - |  | -----------------------------------------------



| |  |  | the priorities placed on various projects by governmental entities;
| | - |  | -------------------------------------------------------------------

| |  |  | federal, state and local government spending levels, including budgetary constraints related to capital projects and the ability to obtain financing; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the ability of governmental entities to obtain environmental approvals, right-of-way permits and other required approvals and permits.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

Decreases in the number of, or government funding of, public water transmission projects would adversely affect our business, financial position,
results of operations, or cash flows.

Project delays in public water transmission projects could adversely affect our business.The
public water agencies constructing water transmission projects generally announce the projects well in advance of the bidding and construction process. It is not unusual for projects to be delayed and rescheduled. Projects are delayed and
rescheduled for a number of reasons, including changes in project priorities, difficulties in complying with environmental and other government regulations and additional time required to acquire rights-of-way or property rights. Delays in public
water transmission projects may occur with too little notice to allow us to replace those projects in our manufacturing schedules. As a result, our business, financial position, results of operations or cash flows may be adversely affected by
unplanned downtime.

We operate in highly competitive industries, and increased competition could reduce our gross profit and net
income.We face significant competition in all of our businesses. Orders in the water transmission business are competitively bid, and price competition can be vigorous. Price competition may reduce the gross margin on sales, which may adversely
affect overall profitability. Other competitive factors include timely delivery, ability to meet customized specifications and high freight costs. Although our water transmission manufacturing facilities in Oregon, Colorado, California, West
Virginia, Texas, Utah and Mexico allow us to compete effectively throughout the United States, Canada and Mexico, we cannot assure you that new or existing competitors will not establish new facilities or expand capacity within our market areas. New
or expanded facilities or new competitors could have a material adverse effect on our ability to capture market share and maintain product pricing in our water transmission business. There are many competitors in the tubular products business, and
price is often a prime consideration for purchase of our products. Price competition may reduce our gross profit, which may adversely affect our net income. Some of our competitors have greater financial, technical and marketing resources than we
do. We cannot assure you that we will be able to compete successfully with our competitors. Failure to compete successfully could reduce our gross profit and net income, as well as have a material adverse effect on our business, financial position,
results of operations or cash flows.

Operating problems in our business could adversely affect our business, financial position,
results of operations or cash flows.Our manufacturing operations are subject to typical hazards and risks relating to the manufacture of similar products such as:



| |  |  | explosions, fires, inclement weather and natural disasters;
| | - |  | -----------------------------------------------------------



| |  |  | mechanical failure;
| | - |  | -------------------



| |  |  | unscheduled downtime;
| | - |  | ---------------------



| |  |  | labor difficulties;
| | - |  | -------------------



| |  |  | an inability to obtain or maintain required licenses or permits; and
| | - |  | --------------------------------------------------------------------



| |  |  | environmental hazards such as chemical spills, discharges or releases of toxic or hazardous substances or gases into the environment or workplace.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

The occurrence of any of these operating problems at our facilities may have a material adverse effect on
the productivity and profitability of a particular manufacturing facility or on our operations as a whole, during and after the period of these operating difficulties. These operating problems may also cause personal injury and loss of life, severe
damage to or destruction of property and equipment, and environmental damage. In addition, individuals could seek damages for alleged personal injury or property damage. Furthermore, we could be subject to present and future claims with respect to
workplace exposure, workers compensation and other matters. Although we maintain property and casualty insurance of the types and in the amounts that we believe are customary for our industries, we cannot assure you that our insurance coverage
will be adequate for liability that may be ultimately incurred or that such coverage will continue to be available to us on commercially reasonable terms. Any claims that result in liability exceeding our insurance coverage could have an adverse
effect on our business, financial position, results of operations or cash flows.

Our water transmission business faces competition from
concrete and ductile iron pipe manufacturers.Water transmission pipe is manufactured generally from steel, concrete or ductile iron. Each pipe material has advantages and disadvantages. Steel and concrete are more common materials for larger
diameter water transmission pipelines because ductile iron pipe generally is limited in diameter due to its manufacturing process. The public agencies and engineers who determine the specifications for water transmission projects analyze these pipe
materials for suitability for each project. Individual project circumstances normally dictate the preferred material. If we experience cost increases in raw materials, labor and overhead specific to our industry or the location of our facilities,
while competing products or companies do not experience similar changes, we could experience an adverse change in the demand, price and profitability of our products, which could have a material adverse effect on our business, financial position,
results of operations or cash flows.

Our quarterly results of operations are subject to significant fluctuation.Our net sales and
operating results may fluctuate significantly from quarter to quarter due to a number of factors, including:



| |  |  | the schedule of production of water transmission orders, including the timing of raw material receipts or unplanned down time due to project delays;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the commencement, completion or termination of contracts during any particular quarter;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | the seasonal variation in demand for tubular products;
| | - |  | ------------------------------------------------------



| |  |  | fluctuations in the cost of steel and other raw materials; and
| | - |  | --------------------------------------------------------------



| |  |  | competitive pressures.
| | - |  | ----------------------

Results of
operations in any period are not indicative of results for any future period, and comparisons between any two periods may not be meaningful.

We depend on our senior management team, and the loss of any member could adversely affect our operations.Our success depends on the management and leadership skills of our senior management team. The loss of any of these
individuals, particularly Brian W. Dunham, our president and chief executive officer, or our inability to attract, retain and maintain additional personnel, could prevent us from fully implementing our business strategy. We cannot assure you that we
will be able to retain our existing senior management personnel or to attract qualified personnel when needed. We have not entered into employment agreements with any of our senior management personnel.

Fluctuations in steel prices may affect our future results of operations.Purchased steel represents a substantial portion of our cost of sales,
particularly in our tubular products business. The steel industry is highly cyclical in nature, and, at times, pricing can be highly volatile due to a number of factors beyond our control, including general economic conditions, import duties, other
trade restrictions and currency exchange rates. This volatility can significantly affect our gross profit. Although we seek to recover increases in steel prices through

##### Table of Contents

price increases in our products, we have not always been completely successful. Any increase in steel prices that is not offset by an increase in our prices
could have an adverse effect on our business, financial position, results of operations or cash flows.

We may be subject to claims for
damages for defective products, which could adversely affect our business, financial position, results of operations or cash flows.We warrant our products to be free of certain defects. We have, from time to time, had claims alleging defects in
our products. While these claims have generally not been material, we cannot assure you that we will not experience material product liability losses in the future or that we will not incur significant costs to defend such claims. While we currently
have product liability insurance, we cannot assure you that our product liability insurance coverage will be adequate for liability that may be incurred in the future or that such coverage will continue to be available to us on commercially
reasonable terms. Any claims relating to defective products that result in liability exceeding our insurance coverage could have an adverse effect on our business, financial position, results of operations or cash flows.

Sustained increases in fuel costs could have an adverse impact on our profitability.We have recently experienced significant fluctuations in fuel
costs primarily as a result of macro-economic factors beyond our control. The price of fuel fluctuates significantly over time, and events beyond our control could adversely affect the supply and cost of fuel. Although we seek to recover increases
in fuel costs through price increases in our products, we have not always been completely successful. Any increase in fuel costs that is not offset by increases in our prices could have an adverse impact on our business, financial position, results
of operations or cash flows.

Our products might not obtain necessary approvals or achieve market acceptance, which could adversely
affect our growth.We will continue to actively seek to develop new products and to expand our existing products into new markets, but we cannot assure you that we will be successful in these efforts. If we are unsuccessful in developing and
marketing new products, expanding into new markets, or we do not obtain or maintain requisite approvals for our products, the demand for our products could be adversely affected, which could affect our business, financial position, results of
operations or cash flows.

We have foreign operations, which exposes us to the risks of doing business abroad.Our fabrication
facility in Monterrey, Mexico primarily exports products to the United States. Any material changes in the quotas, regulations or duties on imports imposed by the U.S. government and its agencies or on exports imposed by Mexico and its agencies
could adversely affect our operations in Mexico.

We also sell some of our products internationally, and part of our business strategy
contemplates international growth. Our foreign activities are also subject to various other risks of doing business in a foreign country, including:



| |  |  | currency fluctuations;
| | - |  | ----------------------



| |  |  | transportation delays and interruptions;
| | - |  | ----------------------------------------



| |  |  | political, social and economic instability and disruptions;
| | - |  | -----------------------------------------------------------



| |  |  | government embargoes or foreign trade restrictions;
| | - |  | ---------------------------------------------------



| |  |  | the imposition of duties, tariffs and other trade barriers;
| | - |  | -----------------------------------------------------------



| |  |  | import and export controls;
| | - |  | ---------------------------



| |  |  | labor unrest and current and changing regulatory environments;
| | - |  | --------------------------------------------------------------



| |  |  | limitations on our ability to enforce legal rights and remedies; and
| | - |  | --------------------------------------------------------------------



| |  |  | potentially adverse tax consequences.
| | - |  | -------------------------------------

##### Table of Contents

Although our operations have not been materially affected by any such factors to date, no assurance can
be given that our operations may not be adversely affected in the future. Any of these events could have an adverse effect on our operations in the future by reducing the demand for our products and services, decreasing the prices at which we can
sell our products or otherwise having an adverse effect on our business, financial position, results of operations or cash flows. We cannot assure you that we will continue to operate in compliance with applicable customs, currency exchange control
regulations, transfer pricing regulations or any other laws or regulations to which we may be subject. We also cannot assure you that these customs, regulations or laws will not be modified.

We have a significant amount of outstanding debt.We have financed our operations through cash flow from operations, available borrowings and
other financing arrangements. As of December 31, 2008, we had approximately $121.0 million of outstanding debt.

Our debt and our debt
service obligations could:



| |  |  | limit our ability to obtain additional financing for working capital or other purposes in the future;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | reduce the amount of funds available to finance our operations, capital expenditures and other activities;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | increase our vulnerability to economic downturns, illiquid capital markets, and adverse industry conditions;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | limit our flexibility in responding to changing business and economic conditions, including increased competition;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | place us at a disadvantage when compared to our competitors that have less debt; and
| | - |  | ------------------------------------------------------------------------------------



| |  |  | with respect to our borrowings that bear interest at variable rates, cause us to be vulnerable to increases in interest rates.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------

Our ability to make scheduled payments on our debt will depend on our future operating performance and cash flow, which are subject to prevailing
economic conditions, prevailing interest rate levels and other financial, competitive and business factors, many of which are beyond our control.

Additionally, the agreements governing our outstanding debt include financial and other restrictive covenants that impose certain requirements with respect to our financial condition and results of operations and general business
activities. These covenants could adversely affect us by limiting our ability to plan for or react to market conditions or to meet our capital needs. These covenants require us to maintain certain financial ratios and place restrictions on, among
other things, our ability to incur certain additional debt and to create liens or other encumbrances on assets. A failure to comply with the requirements of these covenants, if not waived or cured, could permit acceleration of the related debt and
acceleration of debt under other instruments that include cross-acceleration or cross-default provisions. If any of our debt is accelerated, we cannot assure you that we would have sufficient assets to repay such debt or that we would be able to
refinance such debt on commercially reasonable terms or at all.

Our backlog is subject to reduction and cancellation.Backlog
represents products or services that our customers have committed to purchase from us. Our backlog as of December 31, 2008 was $190 million. Our backlog is subject to fluctuations; moreover, cancellations of purchase orders or reductions of
product quantities could materially reduce our backlog and, consequently, future revenues. Our failure to replace canceled or reduced backlog could result in lower revenues, which could adversely affect our business, financial position, results of
operations or cash flows.

Our tubular products business has faced intense competition from imports in the past.The level of
imports of tubular products has historically impacted the domestic tubular products market. High levels of imports may reduce the volume of tubular products sold by domestic producers and depress selling prices of



10



---

##### Table of Contents

tubular products. We believe import levels are affected by, among other things, overall worldwide demand for tubular products, the trade practices of foreign
governments, government subsidies to foreign producers and governmentally imposed trade restrictions in the United States. Increased imports of tubular products in the United States and Canada could adversely affect our business, financial position,
results of operations or cash flows.

We are subject to stringent environmental and health and safety laws, which may require us to
incur substantial compliance and remediation costs, thereby reducing our profits.We are subject to many federal, state, local and foreign environmental and health and safety laws and regulations, particularly with respect to the use, handling,
treatment, storage, discharge and disposal of substances and hazardous wastes used or generated in our manufacturing processes. Compliance with these laws and regulations is a significant factor in our business. We have incurred, and expect to
continue to incur, significant expenditures to comply with applicable environmental laws and regulations. Our failure to comply with applicable environmental laws and regulations and permit requirements could result in civil or criminal fines or
penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing operations or requiring corrective measures, installation of pollution control equipment or remedial actions.

We are currently, and may in the future be, required to incur costs relating to the investigation or remediation of property, and for addressing
environmental conditions, including, but not limited to, the issues associated with our Portland, Oregon facility as discussed in BusinessLegal Proceedings below. Some environmental laws and regulations impose liability and
responsibility on present and former owners, operators or users of facilities and sites for contamination at such facilities and sites without regard to causation or knowledge of contamination. Consequently, we cannot assure you that existing or
future circumstances, the development of new facts or the failure of third parties to address contamination at current or former facilities or properties will not require significant expenditures by us.

We expect to continue to be subject to increasingly stringent environmental and health and safety laws and regulations. It is difficult to predict the
future interpretation and development of environmental and health and safety laws and regulations or their impact on our future earnings and operations. We anticipate that compliance will continue to require capital expenditures and operating costs.
Any increase in these costs, or unanticipated liabilities arising, for example, out of discovery of previously unknown conditions or more aggressive enforcement actions, could adversely affect our results of operations, and there is no assurance
that they will not have a material adverse effect on our business, financial position, results of operations or cash flows.

We face
risks in connection with potential acquisitions.Acquiring businesses that complement or expand our operations has been an important element of our business strategy, and we continue to evaluate potential acquisitions that may expand and
complement our business. We may not be able to successfully identify attractive acquisition candidates or negotiate favorable terms in the future. Furthermore, our ability to effectively integrate any future acquisitions will depend on, among other
things, the adequacy of our implementation plans, the ability of our management to oversee and operate effectively the combined operations and our ability to achieve desired operational efficiencies. If we are unable to successfully integrate the
operations of any businesses that we may acquire in the future, our business, financial position, results of operations or cash flows could be adversely affected.

The relatively low trading volume of our common stock may limit your ability to sell your shares.Although our shares of common stock are listed on the Nasdaq Global Select Market, we have historically
experienced a relatively low trading volume. If we have a low trading volume in the future, holders of our shares may have difficulty selling a large number of shares of our common stock in the manner or at a price that might otherwise be
attainable.

The market price of our common stock could be subject to significant fluctuations.Among the
factors that could affect our stock price are:



| |  |  | our operating and financial performance and prospects;
| | - |  | ------------------------------------------------------



| |  |  | quarterly variations in the rate of growth of our financial indicators, such as earnings per share, net income and sales;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in revenue or earnings estimates or publication of research reports by analysts;

| |  |  | strategic actions by us or our competitors, such as acquisitions or restructuring;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | sales of our common stock by shareholders;
| | - |  | ------------------------------------------



| |  |  | relatively low trading volume;
| | - |  | ------------------------------



| |  |  | general market conditions and market expectations for our industry and the financial health of our customers; and
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | domestic and international economic, legal and regulatory factors unrelated to our performance.
| | - |  | -----------------------------------------------------------------------------------------------

The stock markets in general have experienced broad fluctuations that have often been unrelated to the operating performance of particular companies.
These broad market fluctuations may adversely affect the trading price of our common stock.

Certain provisions of our governing
documents and Oregon law could discourage potential acquisition proposals.Our articles of incorporation contain provisions that:



| |  |  | classify the board of directors into three classes, each of which serves for a three-year term with one class elected each year;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide that directors may be removed by shareholders only for cause and only upon the affirmative vote of 75% of the outstanding shares of common stock; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | permit the board of directors to issue preferred stock in one or more series, fix the number of shares constituting any such series and determine the voting powers
and all other rights and preferences of any such series, without any further vote or action by our shareholders.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In
addition, we are subject to the Oregon Business Combination Act, which imposes certain restrictions on business combination transactions and may encourage parties interested in acquiring us to negotiate in advance with our board of directors. We
also have a shareholder rights plan that acts to discourage any person or group from making a tender offer for, or acquiring, more than 15% of our common stock without the approval of our board of directors. Any of these provisions could discourage
potential acquisition proposals, could deter, delay or prevent a change in control that our shareholders consider favorable and could depress the market value of our common stock.

As of December 31, 2008, we owned all of our facilities except for our Pleasant Grove
facility and one of our Saginaw, Texas facilities, which are leased. We also own an electric resistance mill in Portland, Oregon and a facility in Bossier City, Louisiana, which are not currently operating; however, we are in the process of moving
the mill and reopening the Bossier City facility.

We have available manufacturing capacity from time to time at each of our facilities. To
take advantage of market opportunities, we may identify capital projects that will allow us to expand our manufacturing facilities to meet expected growth opportunities. We believe the quality and productive capacity of our facilities are sufficient
to maintain our competitive position for the foreseeable future.



|Item 3. | Legal Proceedings
|------- | -----------------

On December 1, 2000, a
section of the lower Willamette River known as the Portland Harbor was included on the National Priorities List (NPL) at the request of the U.S. Environmental Protection Agency (EPA). While our 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. We and 68 other parties were notified by EPA and the Oregon Department of
Environmental Quality (ODEQ) of potential liability under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). As of the end of 2008 more than 200 potentially responsible parties (PRPs) on and
nearby the river have been asked to file information disclosure reports with EPA. By agreement with EPA, 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 (RI/FS) of the Portland Harbor is currently being directed by a group of PRPs known as the Lower Willamette Group (LWG). We made a payment of $175,000 to the LWG in June 2007 as part of an
interim settlement, and we are under no obligation to any make further payment. The RI/FS is expected to be completed by the LWG in 2009.

In 2001, groundwater containing elevated volatile organic compounds (VOCs) was identified in one localized area of our 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 our property. On January 25, 2005 we entered into a Voluntary Agreement for Remedial Investigation and Source Control Measures (Agreement) with ODEQ related
to the 2001 discovery. We performed Remedial Investigation (RI) work required under the Agreement and submitted a Remedial Investigation/Source Control

##### Table of Contents

Evaluation Report to ODEQ on December 30, 2005. The conclusions of the report indicate that VOCs in 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. ODEQ has recommended further RI work on
groundwater, soil and storm water at the site. That work is ongoing.

Based on the RI and reporting required under our Portland, Oregon
manufacturing facilitys National Pollutant Discharge Elimination System permit for storm water, the Company and ODEQ have identified a possible source of small amounts of polynuclear aromatic compounds (PAHs) and polychlorinated
biphenyls (PCBs) 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 in the slip have revealed concentration of PAHs, PCBs and zinc which
are common constituents in urban storm water discharges. To minimize the zinc traces in the storm water, we have undertaken a program to coat the roofs of a substantial part of our facility.

Concurrent with the activities of EPA and ODEQ, the Portland Harbor Natural Resources Trustee Council (Trustees) sent some or all of the same
parties, including us, a notice of intent to perform an Injury Assessment for the Portland Harbor Site to determine the nature and extent of natural resource damages under CERCLA section 107. Natural resource damages focus on site restoration as
opposed to actions to remove or remediate hazardous substances. The Trustees for the Portland Harbor Site consist of representatives from six Northwest Indian Tribes and three federal agencies. The Trustees act independently of EPA and ODEQ but we
expect their assessment will be coordinated with the RI/FS work underway at the Portland Harbor Site. The Trustees have encouraged potentially responsible parties to voluntarily participate in the funding of their injury assessment. We have not
assumed any payment obligation or liability related to the Trustees assessment.

The extent of our participation in these various
matters in not known, and no further adjustment to our financial statements has been recorded as of December 31, 2008.

We operate our
facilities under numerous governmental permits and licenses relating to air emissions, storm water run-off, and other matters. Our operations are also governed by many other laws and regulations, including those relating to workplace safety and
worker health, principally the Occupational Safety and Health Act and regulations there under which, among other requirements, establish noise and dust standards. We believe we are in material compliance with our permits and licenses and these laws
and regulations, and we do not believe that future compliance with such laws and regulations will have a material adverse effect on our financial position, results of operations or cash flows. To assist with environmental compliance programs, we
have employed an environmental specialist.

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

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 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, 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 due to numerous factors including changes in demand for our products, product mix, bidding activity, the
timing of customer orders and deliveries, the price and availability of raw materials, excess or shortage of production capacity, international trade policy and regulations and other risks discussed at Item 1A under the caption Risk
Factors and from time to time in our other Securities and Exchange Commission filings and reports. In addition, such statements could be affected by general industry and market conditions and growth rates, and general domestic and
international economic conditions. 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

We are a 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 pipeline systems 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 pipeline systems are produced by our Water Transmission Group from six manufacturing facilities strategically
located across the United States in Portland, Oregon; Denver, Colorado; Adelanto, California; Parkersburg, West Virginia; Saginaw, Texas; Pleasant Grove, Utah; and one facility located in Monterrey, Mexico. Our Water Transmission Group accounted for
approximately 62% of net sales in 2008.

In February 2009, we announced a temporary shutdown of our Utah facility, as we do not currently
see sufficient near-term work located nearby to justify its operation at this time. We will maintain the equipment at this location and closely monitor the project opportunities in and around Utah. We hope to be able to start up this facility again
in the future.

Our water infrastructure products are sold generally to installation contractors, who include our products in their bids to
municipal agencies or privately-owned water companies for specific projects. We believe our sales are substantially driven by spending on new water infrastructure with a recent trend towards spending on water infrastructure replacement, repair and
upgrade. Within the total pipeline, our products tend to fit the larger-diameter, higher-pressure applications.

Our Tubular Products Group
operates two manufacturing facilities in Atchison, Kansas, and Houston, Texas and produces a range of products used in several different markets. We currently make energy pipe, fire protection sprinkler pipe, agricultural pipe, traffic signpost
systems and structural pipe that is sold to distributors and used in many different applications. Our Tubular Products Group generated approximately 38% of our net sales in 2008.

Our Tubular Products Groups sales volume is typically driven by non-residential construction spending, energy spending, highway spending and
general economic conditions. Currently, we are focusing the efforts of our Tubular Products Group on products for which we believe we have a sustainable advantage, and we have seen the most significant increase in this groups sales through
growth in energy products.

Our Current Economic Environment

We are monitoring the current economic environment, and while we do not believe the following are necessarily key factors impacting demand for our products, we do believe these factors warrant consideration: the
current recession; the current financial crisis; the changing cost of steel; and the American Recovery and Reinvestment Bill of 2009 (the stimulus plan). Each of the factors will impact our Groups with varying degrees of significance.
Our Water Transmission Group is fundamentally a 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. As such, we do not expect the current recession to
impact this Group in the same way it may impact the Tubular Products Group. We expect the recessionary environment to have the biggest impact to our Tubular Products Group, as sales in our focus markets may decrease as spending in those markets
declines. Likewise, we dont believe the current financial crisis will have a significant impact on the Water Transmission Group in the near term, as most of the projects in our backlog or to be bid in 2009 are already funded; water projects
are typically funded by revenue bonds which are backed by connection fees or monthly water rates, and are not generally funded by access to general tax obligation bonds. Fluctuating steel costs will be a factor in both our Tubular Products Group and
our Water Transmission Group, as our selling prices will adjust as steel costs adjust. Finally, while we are not currently forecasting future sales as a result of the stimulus plan, we do see upside potential; specifically, the infrastructure
portion of the plan may benefit our Water Transmission Group, as funds for water infrastructure development are made available. To a lesser extent, our tubular products markets may also benefit from other types of infrastructure development.

Critical Accounting Policies

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.

Management Estimates:

The preparation of our
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. On an on-going basis, we evaluate all of
our estimates, including those related to revenue recognition, allowance for doubtful accounts, warranties, intangible assets, accrued liabilities, income taxes, and contingencies and litigation. 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. We believe the following critical accounting policies and related
judgments and estimates affect the preparation of our consolidated financial statements.

Revenue Recognition:

Revenue from construction contracts in our water transmission segment is recognized on the percentage-of-completion method, measured by the costs incurred
to date as a percentage of the estimated total costs of each contract. Estimated total costs of each contract are reviewed on a monthly basis by project management and operations personnel for substantially all projects that are fifty percent or
more complete except that major projects, usually over $5.0 million, are reviewed earlier if sufficient production has been completed to provide enough information to revise the original estimated total cost of the project. All cost revisions that
result in the gross profit as a percent of sales increasing or decreasing by more than two percent are reviewed by senior management personnel. Contract costs include all direct material and labor costs and those indirect costs related to contract
performance, such as indirect labor, supplies, tools, repairs and depreciation. Selling, general and administrative costs are charged to expense as incurred. While certain contract costs are reported in the consolidated statements of income as
selling, general and administrative costs, they are included in total contract costs incurred to date used to recognize revenue.

##### Table of Contents

Provisions for losses on uncompleted contracts are made in the period such losses are known. Changes in
job performance, job conditions and estimated profitability, including those arising from contract penalty provisions, foreign currency exchange rate movements, and final contract settlements may result in revisions to costs and income and are
recognized in the period in which the revisions are determined. Historically, actual results have been within managements estimates.

Revenue from our tubular products segment is recognized when all four of the following criteria have been satisfied: persuasive evidence of an arrangement exists; delivery has occurred; the price is fixed or determinable; and collectibility
is reasonably assured.

Allowance for Doubtful Accounts and Product Warranties:

We maintain allowances for estimated losses resulting from the inability of our customers to make required payments and contract disputes, together with a
reserve for warranty claims, based on managements judgment. The extension and revision of credit is established by obtaining credit rating reports or financial information of a potential customer. An allowance is recorded based on a variety of
factors, including our historical collection experience. At least monthly, we review past due balances to identify the reasons for non-payment. We will write off a receivable account once the account is deemed uncollectible, for reasons such as a
bankruptcy filing, deterioration in the customers financial position, contract dispute, product claim or other similar events. As of December 31, 2008, the accounts receivable balance of $75.9 million is reported net of allowances for
doubtful accounts of $1.2 million. We believe the reported allowances at December 31, 2008, are adequate. If the customers financial conditions were to deteriorate resulting in their inability to make payments, or if contract disputes or
warranty claims were to escalate, additional allowances may need to be recorded, which would result in additional expenses being recorded for the period in which such determination was made. Historically, actual results have been within
managements estimates.

Goodwill:

Goodwill represents the excess of cost over the assigned value of the net assets in connection with all acquisitions. Goodwill is reviewed for impairment in accordance with Statement of Financial Accounting Standard (SFAS) 142
Goodwill and Other Intangible Assets. SFAS 142 requires that goodwill and intangible assets with indefinite lives are no longer amortized but are reviewed for impairment annually or more frequently if impairment indicators arise. We
review for impairment by comparing the fair value of the Tubular Products reporting unit, as measured by discounted cash flows, market multiples based on earnings, and other valuation methodologies, to the carrying value. As required under SFAS 142,
we performed our annual assessment for impairment of the goodwill as of December 31, 2008; based on our analysis, we believe no impairment of goodwill exists.

Long-Lived Assets:

Property and equipment are recorded at cost. We depreciate the net book value in excess of the salvage
value using either the units of production method or a straight-line method depending on the classification of the asset.

Property and
equipment are reviewed for impairment in accordance with SFAS 144, Accounting for the Disposal of Long-Lived Assets. We assess impairment of property and equipment whenever changes in circumstances indicate that the carrying values of
the assets may not be recoverable. The recoverable value of long-lived assets is determined by estimating future undiscounted cash flows using assumptions about our expected future operating performance. Our estimates of undiscounted cash flows may
differ from actual cash flow due to, among other things, technological changes, economic conditions, or changes to our business operations. If we determine the carrying value of the property and equipment will not be recoverable, we calculate and
record an impairment loss.

Inventories:

Inventories are stated at the lower of cost or market. Raw material inventories of steel are stated at cost either on a specific identification basis or on an average cost basis. All other raw materials, as well as supplies, are stated on
an average cost basis. Finished goods are stated at cost using the first-in, first-out method of accounting.

Income Taxes:

We record deferred income tax assets and liabilities based upon the difference between the financial statement and income tax bases of assets and
liabilities using enacted income tax rates. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount expected to be realized. Income tax expense is the tax payable for the period and the change during
the period in net deferred income tax assets and liabilities.

In July 2006, the Financial Accounting Standards Board (FASB)
issued Financial Interpretation 48, Accounting for Uncertainty in Income Taxes (FIN 48) which clarifies the accounting for uncertainty in income taxes recognized in the financial statements in accordance with SFAS 109,
Accounting for Income Taxes. FIN 48 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related
appeals or litigation processes, based on the technical merits.

Workers Compensation Insurance:

We are self-insured, or maintain high deductible policies, for losses and liabilities associated with workers compensation claims. Losses are accrued
based upon our estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. There is no assurance that such insurance coverage will adequately protect us
against liability from all potential consequences.

Pension Benefits:

We have two defined benefit pension plans that are frozen. We fund these plans to cover current plan costs plus amortization of the unfunded plan liabilities. To record these obligations, management uses estimates
relating to assumed inflation, investment returns, mortality, employee turnover, and discount rates. Management reviews all of these assumptions on an annual basis.

Derivative Instruments.

We conduct business in various foreign countries, and from time to time
settle transactions in foreign currencies. We have 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. At December 31, 2008 these foreign currency forward contracts were consistent with our strategy for financial risk management; however, they do not meet the conditions under SFAS 133 Accounting for
Derivative Instruments and Hedging Activities, as amended (SFAS 133) to qualify for hedge accounting treatment. Consequently, these instruments are remeasured at fair value on each balance sheet date and resulting gains and losses
are recognized in net income.

Foreign Currency Transactions

We record foreign currency transactions in accordance with SFAS 52 Foreign Currency Translation. Foreign currency transaction gains and losses are included in net income.

Year Ended December 31, 2008 Compared to Year Ended December 31, 2007

Net sales.Net sales increased to $439.7 million in 2008 from $382.8 million in 2007. No single customer accounted for 10% or more of total
net sales in 2008 or 2007.

Water Transmission sales decreased 5.5% to $271.9 million in 2008 from $287.8 million in 2007. Net sales for
the year decreased over the prior year as a result of a decline in net sales in the fourth quarter; this decline was due to the following: a major project was postponed in October, and we had no opportunity to replace this volume; we shut down our
highest volume production line during the fourth quarter to install a new spiral weld mill; and finally, weather issues impacted production in all but two of our facilities. 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 increased 76.6% to
$167.8 million in 2008 from $95.0 million in 2007. The majority of the increase in net sales over last year resulted from increased sales prices that accompanied rising steel costs, combined with improved energy product sales and solid
performance by our other products.

Gross profit.Gross profit increased to $93.7 million (21.3% of total net sales) in 2008
from $70.2 million (18.3% of total net sales) in 2007.

Water Transmission gross profit decreased 9.5% to $54.5 million (20.0% of segment
net sales) in 2008 from $60.2 million (20.9% of segment net sales) in 2007. Water Transmission gross profit decreased primarily due to the decreased plant utilization in the fourth quarter of 2008.

Gross profit from Tubular Products increased 291.5% to $39.2 million (23.4% of segment net sales) in 2008 from $10.0 million (10.5% of segment net sales)
in 2007. The majority of the increase in gross profit is a result of increased volume of energy product at higher unit sales prices compared to the previous mix of products, combined with generally higher selling prices.

Selling, general and administrative expenses.Selling, general and administrative expenses
increased 14.5% to $35.2 million in 2008 from $30.7 million in 2007. Selling, general and administrative expenses as a percentage of total net sales remained consistent at 8.0% in 2008 and 2007.

Interest expense.Interest expense decreased slightly from $6.8 million in 2007 to $6.4 million in 2008. The decrease in interest expense
was a result of lower average interest rates, partially offset by higher average borrowings.

Income taxes. Our effective tax
rate was approximately 38.0% in 2008 and 36.3% in 2007. The increase in our effective tax rate was mainly due to the additional accrual of a contingent liability related to ongoing income tax audits.

Year Ended December 31, 2007 Compared to Year Ended December 31, 2006

Net sales.Net sales increased to $382.8 million in 2007 from $346.6 million in 2006. No single customer accounted for 10% or more of total net sales in 2007 or 2006.

Water Transmission sales increased 9.9% to $287.8 million in 2007 from $261.8 million in 2006. Net sales for the year increased over the prior year as a
result of a consistent higher production level in most of our facilities. The higher production resulted from the increased backlog at the beginning of 2007 of $198.2 million compared to $125.6 million at the beginning of 2006. This allowed the
majority of our facilities to increase plant utilization in 2007 and, combined with solid bookings early in the year, maintain this level of production throughout the year. In addition to increased sales, the stronger demand resulted in a record
backlog at December 31, 2007 of $211.3 million.

Tubular Products sales increased 12.1% to $95.0 million in 2007 from $84.8 million in
2006. The majority of the increase in net sales over last year resulted from improved energy product and fire protection sprinkler pipe sales.

Gross profit.Gross profit increased to $70.2 million (18.3% of total net sales) in 2007 from $56.7 million (16.4% of total net sales) in 2006.

Water Transmission gross profit increased 26.0% to $60.2 million (20.9% of segment net sales) in 2007 from $47.8 million (18.2% of segment net sales) in
2006. Water Transmission gross profit increased due to higher plant utilization, productivity improvements, and the reduction of rent expense as a result of the purchase in the fourth quarter of 2006 of manufacturing equipment that we previously
leased under certain operating leases.

Gross profit from Tubular Products increased 12.0% to $10.0 million (10.5% of segment net sales) in
2007 from $8.9 million (10.5% of segment net sales) in 2006. The increase in the gross profit is consistent with our increase in sales.

Selling, general and administrative expenses.Selling, general and administrative expenses increased 12.1% to $30.7 million (8.0% of total net sales) in 2007 from $27.4 million (7.9% of total net sales) in 2006. The
majority of the increase resulted from an increase in incentive compensation in 2007 and higher professional fees.

Gain on the sale
of assets.In the year ended December 31, 2006, we completed the sale of our manufacturing facility in Riverside, California, and a gain of $7.7 million was recorded.

Interest expense.Interest expense increased slightly from $6.7 million in 2006 to $6.8 million in 2007. The increase in interest expense
resulted from slightly higher average outstanding borrowings on our note payable to financial institution.

Income taxes. Our effective tax rate was approximately 36.3% in 2007 and 33.9% in 2006. The
effective tax rate in 2006 was lower than historical rates, primarily due to research and development tax credits that were recorded during the year on amended income tax returns, and were not repeated in 2007.

Liquidity and Capital Resources

Sources and Uses of Cash

Our principal sources of liquidity generally include operating cash flow and our bank credit agreement. From time to time our long
term capital needs may be met through the issuance of long term debt or additional equity. Our principal uses of liquidity generally include capital expenditures, working capital and debt service. Information regarding our cash flows for the twelve
months ended December 31, 2008 is presented in our consolidated statements of cash flows contained in this Form 10-K, and is further discussed below.

As of December 31, 2008, our working capital (current assets minus current liabilities) was $223.2 million as compared to $181.5 million as of December 31, 2007. Cash and cash equivalents decreased from
$234,000 as of December 31, 2007 to $90,000 as of December 31, 2008.

Net cash used by operating activities in 2008 was $59,000.
This was primarily the result of our net income of $32.3 million combined with a decrease in costs and estimated earnings in excess of billings on uncompleted contracts, net of $20.3 million, offset in part by an increase in inventories of $24.5
million and an increase in trade and other receivables of $26.6 million. The increase in inventory was largely the result of higher steel costs. The decrease in costs and estimated earnings in excess of billings on uncompleted contracts and the
increase in trade and other receivables resulted from timing differences between production, shipment and invoicing of products. We are typically obligated to pay for goods and services within 30 days of receipt, while cash collected from our
construction contracts typically extends for several months. Our construction contract 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 compared to our collection cycle.

Net cash used in investing activities in 2008 was $24.4 million, which primarily resulted from additions of property and equipment across all of our facilities; the most significant of which was two new spiral weld mills.

Net cash provided by financing activities in 2008 was $24.3 million, which resulted from increased net borrowings under the notes payable to financial
institutions of $27.7 million, partially offset by payments on our long-term debt.

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 2009. 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. 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.

Debt

We had the following significant components of debt at December 31, 2008: a $150.0 million credit
agreement, under which $82.1 million was outstanding; $12.9 million of Series A Term Note, $9.0 million of Series B Term Notes, $8.6 million of Series C Term Notes and $4.5 million of Series D Term Notes.

##### Table of Contents

Effective October 15, 2008, we entered into a Second Amendment to Amended and Restated Credit
Agreement (the Second Amended Credit Agreement), which amends the Amended and Restated Credit Agreement dated May 31, 2007. The Second Amended Credit Agreement provides for a revolving loan, swing line loan and letters of credit in
the aggregate amount of up to $150 million, with an option for us to increase that amount to $200 million, subject to lender approval. 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 Second Amended Credit Agreement are collateralized by substantially all of the Companys personal property.

At December 31, 2008, we had $82.1 million outstanding under the credit agreement bearing interest at a weighted average rate of 3.55%. At
December 31, 2008 we had an additional net borrowing capacity under the credit facility of $55.7 million.

The Series A Term Note in
the principal amount of $12.9 million matures on February 25, 2014 and requires annual payments in the amount of $2.1 million that began February 25, 2008 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 $9.0 million mature on June 21, 2014 and require annual payments in the amount of $1.5 million that began
June 21, 2008 plus interest of 8.47% paid quarterly on March 21, June 21, September 21 and December 21. The Series C Term Notes in the principal amount of $8.6 million mature on October 26, 2014 and require
annual payments of $1.4 million that began October 26, 2008 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 $4.5 million
mature on January 24, 2015 and require annual payments in the amount of $643,000 that began January 24, 2009 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 $4.0 million of capital leases outstanding at December 31, 2008, under which certain equipment used in the manufacturing process is leased.
The average interest rate on the capital leases is 5.6%.

The following table sets forth our scheduled contractual commitments that will
affect our future liquidity as of December 31, 2008 (in thousands):

We also have entered into stand-by letters of credit that total approximately $12.3 million as of December 31, 2008. The stand-by letters of credit
relate to customer owned material and workers compensation insurance. Due to the nature of these arrangements and our historical experience, we do not expect to make any material payments under these arrangements.

The credit agreement, the Term Notes and certain of our capital leases all require compliance with the following financial covenants: minimum
consolidated tangible net worth, maximum consolidated total debt to consolidated earnings before interest, taxes, depreciation and amortization (EBITDA) ratio, maximum

consolidated senior debt to EBITDA, a minimum consolidated fixed charge coverage ratio and a minimum asset coverage ratio. These and other covenants included
in our financing agreements impose certain requirements with respect to our financial condition and results of operations, and place restrictions on, among other things, our ability to incur certain additional indebtedness, to create liens or other
encumbrances on assets and capital expenditures. A failure by us to comply with the requirements of these covenants, if not waived or cured, could permit acceleration of the related indebtedness and acceleration of indebtedness under other
instruments that include cross-acceleration or cross-default provisions. At December 31, 2008, we were not in violation of any of the covenants in our debt agreements.

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.

Recent Accounting
Pronouncements

In March 2008 the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities,
an amendment of FASB Statement No. 133 (SFAS 161). SFAS 161 amends and expands the disclosure requirements of SFAS 133 with the intent to provide users of financial statements with an enhanced understanding of: 1) How and why
an entity uses derivative instruments; 2) How derivative instruments and related hedged items are accounted for under SFAS 133 and its related interpretations and 3) How derivative instruments and related hedged items affect an entitys
financial position, financial performance and cash flows. This statement is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. The adoption of
SFAS 161 relates specifically to disclosures, and will not have an impact on our financial position, results of operations or cash flows.

In December 2007 the FASB issued SFAS 141(R), Business Combinations (SFAS 141(R)), which requires the acquiring entity in a business combination to recognize and measure all assets and liabilities assumed in the
transaction and any non-controlling interest in the acquiree at fair value as of the acquisition date. SFAS 141(R) also establishes guidance for the measurement of the acquirer shares issued in consideration for a business combination, the
recognition of contingent consideration, the accounting treatment for pre-acquisition gain and loss contingencies, the treatment of acquisition related transaction costs, and the recognition of changes in the acquirers income tax valuation
allowance and deferred taxes. SFAS 141(R) is effective for fiscal years beginning after December 15, 2008, and is to be applied prospectively as of the beginning of the fiscal year in which the statement is applied. Early adoption is not
permitted. The impact of SFAS 141(R) on the financial position, results of operations or cash flows will depend upon the nature, terms, and size of the acquisitions we consummate after the effective date.

In February 2007 the FASB issued SFAS 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS 159). SFAS
159 permits companies to choose to measure many financial instruments and certain other items at fair value. SFAS 159 seeks to improve the overall quality of financial reporting by providing companies the opportunity to mitigate volatility in
reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The adoption of this
statement did not have a material impact on our financial position, results of operations or cash flows.

In September 2006 the FASB issued
SFAS 157, Fair Value Measurements (SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. SFAS 157 requires companies to
disclose the fair value of its financial instruments according to a fair value hierarchy (i.e., levels 1, 2, and 3, as defined). Additionally, companies are required to provide enhanced disclosure regarding instruments in the level 3 category,
including a reconciliation of the beginning and ending balances separately for each major category of assets and liabilities. SFAS 157 is effective

for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. In February 2008, the
FASB issued Staff Position 157-2, Effective Date of FASB Statement No. 157 (FSP 157-2) which delays the effective date of SFAS 157 for nonfinancial assets and nonfinancial liabilities, except for items that are
recognized or disclosed at fair value in the financial statements on a recurring basis. The adoption of SFAS 157 for financial assets and financial liabilities did not have an impact on our Condensed Consolidated Financial Statements. The full
adoption of SFAS 157 in 2009 for nonfinancial assets and nonfinancial liabilities is also not expected to have a significant impact on our financial position, results of operations or cash flows.



|Item 7A. | Quantitative and Qualitative Disclosure About Market Risk
|-------- | ---------------------------------------------------------

We transact business in various foreign countries, and from time to time settle our transactions in foreign currencies. We have established a program that utilizes foreign currency forward contracts to offset the risk associated with the
effects of certain foreign currency exposures. These contracts are not used for trading or for speculative purposes. By design these contracts are not designated as hedges as defined by SFAS 133; therefore, unrealized gains or losses on these
contracts are recorded in net income. Our foreign currency exposures typically arise from sales contracts denominated in Canadian currency, for which there is exposure associated with potential foreign currency rate changes occurring between the
contract date and the date when the payments are received. Under this program, increases or decreases in our foreign currency exposures are offset by gains or losses on the foreign currency forward contracts, to mitigate the possibility of foreign
currency transaction gains or losses.

At December 31, 2008, we had open sales contracts of CAD$31 million, of which CAD$16 million
was recorded in trade receivables or costs and earnings in excess of billings. To offset our exposure to foreign currency fluctuations in these transactions, we held foreign currency forward contracts with a notional value of CAD$21 million that
have varying maturities of between 1 and 9 months. Management believes that the impact of a near-term 10% appreciation or depreciation of the U.S. dollar relative to the Canadian dollar would not have a significant effect on our financial position,
results of operations, or cash flows.

We are exposed to cash flow and fair value risk due to changes in interest rates with respect to
certain portions of our debt. The debt subject to changes in interest rates is our $150.0 million revolving credit line ($82.1 million outstanding as of December 31, 2008). Management believes our current risk exposure to interest rate
movements to be immaterial.

Evaluation of Disclosure Controls and
Procedures

As of December 31, 2008, an evaluation was carried out under the supervision and with the participation of the
Companys management, including the Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of our disclosure controls and procedures. Based on that evaluation, the CEO and CFO have
concluded that our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported
within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding
required disclosure.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected or is
reasonably likely to materially affect our internal control over financial reporting.

Managements Report on Internal Control Over Financial
Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such
term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our CEO and CFO, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on
the framework inInternal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal ControlIntegrated Framework, our
management concluded that our internal control over financial reporting was effective as of December 31, 2008.

Our independent
registered public accounting firm, Deloitte & Touche LLP, has issued an audit report on our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Northwest Pipe Company

Vancouver, Washington

We have audited the
internal control over financial reporting of Northwest Pipe Company and subsidiaries (the Company) as of December 31, 2008, based on criteria established in Internal ControlIntegrated Frameworkissued by the Committee
of Sponsoring Organizations of the Treadway Commission. The Companys management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Management Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control
over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control
over financial reporting is a process designed by, or under the supervision of, the companys principal executive and principal financial officers, or persons performing similar functions, and effected by the companys board of directors,
management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A
companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of
the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
companys assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal
control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any
evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies
or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial
reporting as of December 31, 2008, based on the criteria established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial
statements and financial statement schedule as of and for the year ended December 31, 2008, of the Company and our report dated March 12, 2009, expressed an unqualified opinion on those financial statements and financial statement
schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Northwest Pipe Company

Vancouver, Washington

We have audited the
accompanying consolidated balance sheets of Northwest Pipe Company and subsidiaries (the Company) as of December 31, 2008 and 2007, and the related consolidated statements of income, stockholders equity, and cash flows for
each of the years then ended. Our audits also included the financial statement schedule for the years ended December 31, 2008 and 2007, listed in the Table of Contents at Item 15. These financial statements and financial statement schedule
are the responsibility of the Companys management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits. The consolidated statements of income, of stockholders
equity and comprehensive income and of cash flows of the Company for the year ended December 31 2006, and the 2006 financial statement schedule, before the retrospective adjustments for the change in segments of the Company discussed in
Note 16 to the consolidated financial statements, were audited by other auditors whose report, dated March 30, 2007, expressed an unqualified opinion on those statements.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of
Northwest Pipe Company and subsidiaries as of December 31, 2008 and 2007, and the results of their operations and their cash flows for each of the years then ended, in conformity with accounting principles generally accepted in the United
States of America. Also, in our opinion, such 2008 and 2007 financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set
forth therein.

We have also audited the retrospective adjustments to the 2006 consolidated financial statements for the change in segments
of the Company discussed in Note 16 to the consolidated financial statements. Our procedures included (1) comparing the adjustment amounts of the Companys segment net sales, gross profit, depreciation and amortization of property and
equipment, and capital expenditures to the Companys underlying analysis and (2) testing the mathematical accuracy of the reconciliations of the segment amounts to the consolidated financial statements. In our opinion, such retrospective
adjustments are appropriate and have been properly applied. However, we were not engaged to audit, review, or apply any procedures to the 2006 consolidated financial statements of the Company other than with respect to the retrospective adjustments
and, accordingly, we do not express an opinion or any other form of assurance on the 2006 consolidated financial statements taken as a whole.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Companys internal control over financial reporting as of December 31, 2008, based on the criteria
established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and per our report dated March 12, 2009, expressed an unqualified opinion on the
Companys internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Northwest Pipe and Company

In our opinion, the consolidated statements of income, of stockholders equity and comprehensive income, and of cash flows of Northwest Pipe
Company and Subsidiaries (the Company) for the year ended December 31, 2006, before the effects of the adjustments to retrospectively change the reporting segment described in Note 16, present fairly, in all material respects, the
results of their operations and their cash flows for the year ended December 31, 2006, in conformity with accounting principles generally accepted in the United States of America (the 2006 financial statements before the effects of the
adjustments discussed in Note 16 are not presented herein). In addition, in our opinion, the financial statement schedule for the year ended December 31, 2006 presents fairly, in all material respects, the information set forth therein when
read in conjunction with the related consolidated financial statements before the effects of the adjustments described above. These financial statements and financial statement schedule are the responsibility of the Companys management. Our
responsibility is to express an opinion on these financial statements and financial statement schedule based on our audit. We conducted our audit, before the effects of the adjustments described above, of these statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our opinion.

We were not engaged to audit, review, or apply any
procedures to the adjustments to retrospectively change the reporting segments described in Note 16 and, accordingly, we do not express an opinion or any other form of assurance about whether such adjustments are appropriate and have properly
applied. Those adjustments were audited by other auditors.

NORTHWEST PIPE COMPANY AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



|1. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
|-- | -------------------------------------------

The
consolidated financial statements include the accounts of Northwest Pipe Company and its wholly owned subsidiaries (the Company). All inter-company balances have been eliminated. The Company has water transmission manufacturing
facilities in Portland, Oregon; Denver, Colorado; Adelanto, California; Parkersburg, West Virginia; Saginaw, Texas; Pleasant Grove, Utah; and Monterrey, Mexico. Tubular products manufacturing facilities are located in Atchison, Kansas; Houston,
Texas; and Bossier City, Louisiana.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets
and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and
on various assumptions that are believed to be reasonable under the circumstances at that time. On an on-going basis, the Company evaluates all of its estimates, including those related to revenue recognition, allowance for doubtful accounts,
warranties, intangible assets, accrued liabilities, income taxes, and contingencies and litigation. Actual results could differ from those estimates under different assumptions or conditions.

Cash and Cash Equivalents

Cash and cash equivalents
consist of cash and short term highly liquid investments with remaining maturities of three months or less when purchased.

Allowance for Doubtful
Accounts and Product Warranties

The Company maintains allowances for estimated losses resulting from the inability of its customers to
make required payments and contract disputes, together with reserves for warranty claims, based on managements judgment. An allowance is recorded for based on a variety of factors, including the historical collection experience with individual
customers. At least monthly, the Company reviews past due balances to identify the reasons for non-payment. The Company will write off a receivable account once the account is deemed uncollectible. The Company believes the reported allowances at
December 31, 2008 and 2007 are adequate. If the customers financial conditions were to deteriorate resulting in their inability to make payments, or if contract disputes or warranty claims were to escalate, additional allowances may need
to be recorded, which would result in additional expenses being recorded for the period in which such determination was made.

Inventories

Inventories are stated at the lower of cost or market. Raw material inventories of steel are stated at cost either on a specific
identification basis or on an average cost basis. All other raw material inventories, as well as supplies, are stated on an average cost basis. Finished goods are stated at cost using the first-in, first-out method of accounting.

Property and Equipment

Property and equipment is
stated at cost. Maintenance and repairs are expensed as incurred and costs of improvements and renewals, including interest where applicable, are capitalized. Depreciation and amortization on the book value in excess of the salvage value are
determined by the units of production method for most equipment, and for the remaining assets by the straight-line method based on the estimated useful lives of the related assets. Upon disposal, costs and related accumulated depreciation of the
assets are removed from the

accounts and resulting gains or losses are reflected in operations. The Company leases certain equipment under long-term capital leases, which are being
amortized on a straight-line basis over the shorter of the lease terms or the estimated useful lives of the assets.

Estimated useful lives
by major classes of property and equipment are as follows:



|                  |  |               |  | 
|----------------- |  | ------------- |  | 
|Land improvements |  | 20  30 years |  | 
|Buildings         |  | 20  40 years |  | 
|Equipment         |  | 3  18 years  |  | 

Goodwill

Goodwill related to the Companys Tubular Products Group of $21.5 million at December 31, 2008 and 2007 represents the excess of cost over the assigned value of the net assets in connection with all
acquisitions. Goodwill is reviewed for impairment in accordance with Statement of Financial Accounting Standard (SFAS) 142 Goodwill and Other Intangible Assets. SFAS 142 requires that goodwill and intangible assets with
indefinite lives are no longer amortized but are reviewed for impairment annually or more frequently if impairment indicators arise. The Company reviews for impairment by comparing the fair value of the Tubular Products reporting unit, as measured
by discounted cash flows, market multiples based on earnings, and other valuation methodologies, to the carrying value. As required under SFAS 142, an annual assessment for impairment of the goodwill was performed as of December 31, 2008 and
2007; based on the analysis, the Company believes no impairment of goodwill exists.

Workers Compensation Insurance

The Company is self-insured, or maintains high deductible policies, for losses and liabilities associated with workers compensation claims. Losses are
accrued based upon the Companys estimates of the aggregate liability for claims incurred using historical experience and certain actuarial assumptions followed in the insurance industry. There is no assurance that such insurance coverage will
adequately protect the Company against liability from all potential consequences.

Pension Benefits

The Company has two defined benefit pension plans that are frozen. The Company funds these plans to cover current plan costs plus amortization of the
unfunded plan liabilities. To record these obligations, management uses estimates relating to assumed inflation, investment returns, mortality, and discount rates. Management reviews all of these assumptions on an annual basis.

Derivative Instruments.

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. At December 31, 2008 these foreign currency forward contracts were consistent with the Companys strategy for financial risk management;
however, they do not meet the conditions under SFAS 133 Accounting for Derivative Instruments and Hedging Activities, as amended (SFAS 133) to qualify for hedge accounting treatment. Consequently, these instruments are
remeasured at fair value on each balance sheet date and resulting gains and losses are recognized in net income.

Foreign Currency Transactions

Foreign currency transactions are recorded in accordance with SFAS 52 Foreign Currency Translation. Foreign currency transactions are included
in net income.

Revenue Recognition

Revenue from construction contracts in the Companys water transmission segment is recognized on the percentage-of-completion method, measured by the percentage of costs incurred to date compared to the estimated
total costs of each contract. Estimated total costs are reviewed monthly and updated by project management and operations personnel for substantially all projects that are fifty percent or more complete, except that major projects, usually over $5.0
million, are reviewed earlier if sufficient production has been completed to provide enough information to revise the original estimated total cost of the project. All cost revisions that result in the gross profit as a percent of sales increasing
or decreasing by more than two percent are reviewed by senior management personnel. Provisions for estimated losses on uncompleted contracts are made in the period such estimated losses are known. Changes in job performance, job conditions and
estimated profitability, including those arising from contract penalty provisions, and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Contract costs
include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation. Selling, general and administrative costs are charged to expense as incurred.
While certain contract costs are reported in the consolidated statements of income as selling, general and administrative costs, they are included in total contract costs incurred to date used to recognize revenue.

Revenue from the Companys tubular products segment is recognized when all four of the following criteria have been satisfied: persuasive evidence
of an arrangement exists; delivery has occurred; the price is fixed or determinable; and collectibility is reasonably assured.

Income Taxes

The Company records deferred income tax assets and liabilities based upon the difference between the financial statement and income tax
bases of assets and liabilities using enacted income tax rates. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount expected to be realized. Income tax expense is the tax payable for the period and
the change during the period in net deferred income tax assets and liabilities.

In July 2006, the Financial Accounting Standards Board
(FASB) issued Financial Interpretation 48, Accounting for Uncertainty in Income Taxes (FIN 48), which clarifies the accounting for uncertainty in income taxes recognized in the financial statements in accordance
with SFAS 109, Accounting for Income Taxes. FIN 48 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions
of any related appeals or litigation processes, based on the technical merits.

Earnings per Share

Basic earnings per share is computed using the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share
is computed using the weighted average number of shares of common stock and dilutive common equivalent shares outstanding during the period. Dilutive common equivalent shares outstanding include the dilutive effect of in-the-money options which are
calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the amount the option holder must pay for exercising stock options, the amount of compensation cost that the Company has
not yet recognized, and the amount of tax benefits that would be recorded in additional paid-in capital when the award becomes deductible are assumed to be used to repurchase shares. Incremental shares of 195,139, 272,492 and 294,586 for the years
ended December 31, 2008, 2007, and 2006, respectively, were used in the calculations of diluted earnings per share. For the year ended December 31, 2008, 1,965 restricted stock units were excluded from the computation of diluted earnings
per share because the effect of their inclusion would have been antidilutive. For the years ended December 31, 2007 and 2006, the calculation of diluted earnings per share included all common equivalent shares.

Concentrations of Credit Risk

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of trade receivables. Trade receivables are generally with a large number of customers, including
municipalities, manufacturers, distributors and contractors, dispersed across a wide geographic base. At December 31, 2008, one customer accounted for 20% of total accounts receivable. No single customer balance accounted for 10% or more of
total accounts receivable at December 31, 2007.

Fair Value of Financial Instruments

The fair values of financial instruments are the amounts at which the instrument could be exchanged in a current transaction between willing parties,
other than in a forced or liquidation sale. The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents, trade receivables, other current assets and current liabilities approximate fair value because of the short
maturity for these instruments. The fair value approximates the carrying value of the Companys borrowings under its long-term arrangements based upon interest rates available for the same or similar loans.

Long-Lived Assets

Property and equipment are
reviewed for impairment in accordance with SFAS 144, Accounting for the Disposal of Long-Lived Assets. The Company assesses impairment of property and equipment whenever changes in circumstances indicate that the carrying values of the
assets may not be recoverable. The recoverable value of long-lived assets is determined by estimating future undiscounted cash flows using assumptions about the expected future operating performance of the Company. The estimates of undiscounted cash
flows may differ from actual cash flow due to, among other things, technological changes, economic conditions, or changes to business operations. If the carrying value of the property and equipment will not be recoverable, an impairment loss is
calculated and recorded.

Share-based Compensation

In accordance with SFAS 123(R) Share-Based Payment (SFAS 123(R)), the Company recognizes the compensation cost of employee services received in exchange for awards of equity instruments based
on the grant date estimated fair value of the awards. The Company recognizes compensation expense related to performance awards based on the probable outcome of the performance conditions. Compensation cost is recognized over the period during which
the employee is required to provide service in exchange for the award, and as forfeitures occur, the associated compensation cost recognized to date is reversed.

See Note 11 for further discussion of the Companys share-based compensation.

Initial Adoption of Staff
Accounting Bulletin No. 108

In September 2006, the SEC staff released Staff Accounting Bulletin No. 108, Considering
the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements (SAB 108). SAB 108 established an approach that requires quantification of financial statement misstatements based on the
effect of the misstatements on each of the Companys financial statements and the related financial statement disclosures.

##### Table of Contents

SAB 108 permitted public companies to initially apply its provisions either by (i) restating prior
financial statements as if the dual approach had always been used or (ii) recording the cumulative effect of initially applying the dual approach as adjustments to the carrying values of assets and liabilities as of
January 1, 2006 with an offsetting adjustment recorded to the opening balance of retained earnings. The Company elected to record the effects of applying SAB 108 using the cumulative effect transition method. The following table summarizes the
effects of applying the guidance in SAB 108 through January 1, 2006 (in thousands). Amounts shown reflect increases (decreases) in the related account balances:

The Company previously quantified these errors under the roll-over method and concluded they were
immaterial, individually and in the aggregate. With respect to accrued liabilities, the Company adjusted the workers compensation accrual to more closely align with estimates provided by an actuary in each of the periods prior to
January 1, 2006, and adjusted property tax expense by $272,000 in 2005. With respect to inventory, the Company adjusted amounts that had previously been capitalized as inventoriable. With respect to property and equipment, net, the Company
expensed internal costs of constructing assets used in the manufacturing process that had previously been capitalized in error. Because of the errors described above, deferred and refundable income taxes required adjustment by $2.2 million related
to years prior to 2006. To record the initial application of SAB 108, the Company recorded a $3.4 million adjustment to decrease retained earnings at January 1, 2006.

Recent Accounting and Reporting Developments

In March 2008 the FASB issued SFAS No. 161,
Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133 (SFAS 161). SFAS 161 amends and expands the disclosure requirements of SFAS 133 with the intent to provide users of
financial statements with an enhanced understanding of: 1) How and why an entity uses derivative instruments; 2) How derivative instruments and related hedged items are accounted for under SFAS 133 and its related interpretations and 3) How
derivative instruments and related hedged items affect an entitys financial position, financial performance and cash flows. This statement is effective for financial statements issued for fiscal years and interim periods beginning after
November 15, 2008, with early application encouraged. The adoption of SFAS 161 relates specifically to disclosures, and will not have an impact on the Companys financial position, results of operations or cash flows.

In December 2007 the FASB issued SFAS 141(R), Business Combinations (SFAS 141(R)), which requires the acquiring
entity in a business combination to recognize and measure all assets and liabilities assumed in the transaction and any non-controlling interest in the acquiree at fair value as of the acquisition date. SFAS 141(R) also establishes guidance for the
measurement of the acquirer shares issued in consideration for a business combination, the recognition of contingent consideration, the accounting treatment for pre-acquisition gain and loss contingencies, the treatment of acquisition related
transaction costs, and the recognition of changes in the acquirers income tax valuation allowance and deferred taxes. SFAS 141(R) is effective for fiscal years beginning after December 15, 2008, and is to be applied prospectively as of
the beginning of the fiscal year in

which the statement is applied. Early adoption is not permitted. The impact of SFAS 141(R) on the financial position, results of operations or cash flows
will depend upon the nature, terms, and size of the acquisitions the Company consummates after the effective date.

In February 2007 the
FASB issued SFAS 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS 159). SFAS 159 permits companies to choose to measure many financial instruments and certain other items at fair value. SFAS 159
seeks to improve the overall quality of financial reporting by providing companies the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge
accounting provisions. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The adoption of SFAS 159 on January 1, 2008, did not have an impact on the Condensed Consolidated Financial Statements.

In September 2006 the FASB issued SFAS 157, Fair Value Measurements (SFAS 157). SFAS 157 defines fair value, establishes a
framework for measuring fair value and requires enhanced disclosures about fair value measurements. SFAS 157 requires companies to disclose the fair value of its financial instruments according to a fair value hierarchy (i.e., levels 1, 2, and 3, as
defined). Additionally, companies are required to provide enhanced disclosure regarding instruments in the level 3 category, including a reconciliation of the beginning and ending balances separately for each major category of assets and
liabilities. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. In February 2008, the FASB issued Staff Position 157-2, Effective Date of
FASB Statement No. 157 (FSP 157-2) which delays the effective date of SFAS 157 for nonfinancial assets and nonfinancial liabilities, except for items that are recognized or disclosed at fair value in the financial statements
on a recurring basis. The adoption of SFAS 157 for financial assets and financial liabilities did not have an impact on the Condensed Consolidated Financial Statements. The full adoption of SFAS 157 in 2009 for nonfinancial assets and nonfinancial
liabilities is also not expected to have a significant impact on the Companys financial position, results of operations or cash flows.



|2. | COSTS AND ESTIMATED EARNINGS IN EXCESS OF BILLINGS ON UNCOMPLETED CONTRACTS AND BILLINGS IN EXCESS OF COSTS AND ESTIMATED EARNINGS:
|-- | -----------------------------------------------------------------------------------------------------------------------------------

The sum of costs and estimated earnings in excess of billings on uncompleted contracts represents revenue earned under the percentage of completion method
but not billable based on the terms of the contracts. These amounts are billed based on the terms of the contracts, which include achievement of milestones, partial shipments or completion of the contracts. Billings in excess of costs and estimated
earnings represents amounts billed based on the terms of the contracts in advance of costs incurred and revenue earned.

|9. | DERIVATIVE INSTRUMENTS AND FOREIGN CURRENCY TRANSACTIONS:
|-- | ---------------------------------------------------------

At December 31, 2008, the Company held five foreign currency forward contracts with a notional value of CAD$20.8 million that have varying maturities of between 1 and 9 months. The Company revalued the Canadian foreign currency forward
contracts to fair market value at December 31, 2008. By design, these forward contracts are not designated as hedges as defined by SFAS 133; therefore, unrealized gains of $5.2 million on these contracts are recorded in net income. Also
recorded in net income are foreign currency transaction losses of $4.4 million resulting from the revaluation of our Canadian sales contracts.

|10. | FAIR VALUE MEASUREMENT:
|--- | -----------------------

Effective January 1,
2008, the Company adopted SFAS 157, as described in Note 1. SFAS 157 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).

The following table summarizes information regarding the Companys
financial assets and financial liabilities that are measured at fair value as of December 31, 2008 (in thousands):



|            |  |                         |       |         |   |         |  |         |       |  |   |

|Description |  | BalanceDecember 31,2008 |       | Level 1 |   | Level 2 |  | Level 3

The Company uses derivatives to offset the risk associated with the effects of certain foreign
currency exposures. These contracts are not for trading or for speculative purposes. Fair value measurements for the Companys derivatives are classified under Level 2 because such measurements are based on third-party valuation models.



|11. | RETIREMENT PLANS:
|--- | -----------------

The Company has a defined
contribution retirement plan that covers substantially all of its employees and provides for Company matches of up to 50% of the first 6% of employee contributions to the plan, subject to certain limitations. The defined contribution retirement plan
offers fifteen investment options.

The Company has a non-qualified retirement savings plan that covers the officers and selected highly
compensated employees. The non-qualified plan generally matches up to 50% of the first $10,000 of employee contributions to the plan, subject to certain limitations. It also provides a Company funded component for the officers with a retirement
target fund. The retirement target fund amount is an actuarially estimated amount necessary to provide 35% of final base pay after a 35-year career with the Company or 1% of final base pay per year of service. The actual benefit, however, assumes an
investment growth at 8% per year. Should the investment growth be greater than 8%, the benefit will be more, but if it is less than 8%, the amount will be less and the Company does not make up any deficiency.

The Company also has two noncontributory defined benefit plans. Both plans are frozen, and participants are fully vested in their accrued benefits as of
the date each plan was frozen. No additional participants can be added to the plans and no additional service can be earned by participants subsequent to date the plans were frozen. The funding policy for each noncontributory defined benefit plan is
based on current plan costs plus amortization of the unfunded plan liability. All current employees covered by these plans are now covered by the defined contribution retirement plan. As of December 31, 2008 the Company had recorded, in
accordance with the actuarial valuation, an accrued pension liability of $1.8 million and an unrecognized actuarial loss, net of tax of $2.9 million in accumulated other comprehensive income. As of December 31, 2007, the Company had recorded a
prepaid benefit cost of $511,000, and an unrecognized actuarial loss, net of tax of $1.5 million in accumulated other comprehensive income. Additionally, as of December 31, 2008 and 2007, the accumulated benefit obligation was $5.3 million and
$4.6 million, respectively, and the fair value of plan assets was $3.6 million and $5.1 million, respectively.

Total expense for all
retirement plans in 2008, 2007 and 2006 was $1.3 million, $1.0 million and $1.2 million, respectively.

|12. | SHARE-BASED COMPENSATION PLANS:
|--- | -------------------------------

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 Options Plan for Nonemployee Directors and the Amended 1995 Stock Incentive Plan, under which previously granted options
remain outstanding. The plans provide that options become exercisable according to vesting schedules, which range from immediate for nonemployee directors to ratably over a 60-month period for all other options. Options terminate 10 years from the
date of grant. The plans also provide for other equity instruments, such as restricted stock units and performance awards, which grant the right to receive a specified number of shares over a specified period of time, which is generally three annual

The following are the options exercisable at the corresponding weighted average exercise price at

There were no
options granted during 2008. The weighted average grant date fair value of options granted during 2007 and 2006 was $17.40 and $12.88, respectively. The fair value of options granted in 2007 and 2006 is estimated as of the date of grant using the
Black-Scholes option-pricing model with the assumptions noted in the following table. The risk-free interest rate is based on the U.S. Treasury yield curve corresponding to the expected life of the option in effect at the time of the grant. The
expected life is based on the historical exercise pattern of similar groups of employees. Expected volatility is based on the historical volatility of the Companys stock.

In June 1999, the Board
of Directors adopted a Shareholder Rights Plan (the Plan) designed to ensure fair and equal treatment for all shareholders in the event of a proposed acquisition of the Company by enhancing the ability of the Board of Directors to
negotiate more effectively with a prospective acquirer, and reserved 150,000 shares of Series A Junior Participating Preferred Stock (Preferred Stock) for purposes of the Plan. In connection with the adoption of the Plan, the Board of
Directors declared a dividend distribution of one preferred stock purchase right (a Right) per share of common stock, payable to shareholders of record on July 9, 2000. Each right represents the right to purchase one one-hundredth
of a share of Preferred Stock at a price of $83.00, subject to adjustment. The Rights will be exercisable only if a person or group acquires, or commences a tender offer to acquire, 15% or more of the Companys outstanding shares of common
stock. Subject to the terms of the Plan and upon the occurrence of certain events, each Right would entitle the holder to purchase common stock of the Company, or of an acquiring company in certain circumstances, having a market value equal to two
times the exercise price of the Right. The Company may redeem the Rights at a price of $0.01 per Right under certain circumstances.

Litigation

On December 1, 2000, a section of the lower Willamette River known as the Portland Harbor was included on the National Priorities List
(NPL) at the request of the U.S. Environmental Protection Agency (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 68 other parties were notified by
EPA and the Oregon Department of Environmental Quality (ODEQ) of potential liability under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). As of the end of 2008 more than 200 potentially
responsible parties (PRPs) on and nearby the river have been asked to file information disclosure reports with EPA. By agreement with EPA, 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 (RI/FS) of the Portland Harbor is currently being directed by a group of PRPs known as the Lower Willamette Group (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 any make further payment. The RI/FS is expected to be completed by the LWG in 2009.

In 2001, groundwater containing elevated volatile 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 ODEQ related to the 2001 discovery. The Company performed Remedial Investigation (RI) work required under the Agreement and
submitted a Remedial Investigation/Source Control Evaluation Report to ODEQ on December 30, 2005. The conclusions of the report indicate that VOCs in 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. ODEQ has recommended further RI work on groundwater, soil and storm water at the
site. That work is ongoing.

Based on the RI and reporting required under the Portland, Oregon manufacturing facilitys National
Pollutant Discharge Elimination System permit for storm water, the Company and ODEQ have identified a possible source of small amounts of polynuclear aromatic compounds (PAHs) and polychlorinated biphenyls (PCBs) 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 in the slip have revealed concentration of PAHs, PCBs and zinc which are common constituents in urban
storm water discharges. To minimize the zinc traces in the storm water, the Company has undertaken a program to coat the roofs of a substantial part of the facility.

Concurrent with the activities of EPA and 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
an Injury Assessment for the Portland Harbor Site to determine the nature and extent of natural resource damages under CERCLA section 107. Natural resource damages focus on site restoration as opposed to actions to remove or remediate hazardous
substances. The Trustees for the Portland Harbor Site consist of representatives from six Northwest Indian Tribes and three federal agencies. The Trustees act independently of EPA and ODEQ but the Company expects their assessment will be coordinated
with the RI/FS work underway at the Portland Harbor Site. The Trustees have encouraged potentially responsible parties to voluntarily participate in the funding of their injury assessment. The Company has not assumed any payment obligation or
liability related to the Trustees assessment.

The extent of the Companys participation in these matters is not known, and no
further adjustment to the consolidated financial statements has been recorded as of December 31, 2008.

The Company operates its
facilities under numerous governmental permits and licenses relating to air emissions, storm water run-off, and other matters. The Companys operations are also governed by many other laws and regulations, including those relating to workplace
safety and worker health, principally the Occupational Safety and Health Act and regulations there under which, among other requirements, establish

noise and dust standards. The Company believes it is in material compliance with its permits and licenses and these laws and regulations, and does not
believe that future compliance with such laws and regulations will have a material adverse effect on its financial position, 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 $12.3 million. The stand-by letters of credit relate to customer owned raw materials and workers compensation insurance.

As of December 31, 2008, the Company had approximately $696,000 of federal net operating loss
carryforwards and $6.3 million of state net operating loss carryforwards as a result of the acquisition of Thompson Pipe and Steel, which are limited in their use to approximately $348,000 per year during the 15 year carryforward period which
expires in 2010. During the year ended December 31, 2008, the Company recorded a decrease in the valuation allowance of $74,000 related to the state net operating loss carryforwards. As it was considered more likely than not the additional
benefits would be realized, the valuation allowance was adjusted based upon current and anticipated future taxable income, state tax rates, and state apportionment.

A summary of the changes in the unrecognized tax benefits during the year ended December 31, 2008 is presented below (in thousands):

|Unrecognized tax benefits at December 31, 2008               |  | $ | 1,417 |  

All of the balance of unrecognized tax benefits at December 31, 2007 and 2008 would affect
the Companys effective tax rate if recognized.

The Company files income tax returns in the United States Federal jurisdiction, in one foreign
jurisdiction, and in many state jurisdictions. With few exceptions, the Company is no longer subject to US Federal or state income tax examinations for years before 2003. The Company is currently attempting to resolve income tax audits relating to
the 2005 tax filings in various jurisdictions, and certain amendments filed. The Company does not believe it is reasonably possible the total amounts of unrecognized tax benefits will change significantly prior to December 31, 2009; however,
actual results could differ from those currently expected.

The Company recognizes interest and penalties related to uncertain tax
positions in income tax expense. As of December 31, 2008, the Company has approximately $145,000 of accrued interest related to uncertain tax positions.



|16. | SEGMENT INFORMATION:
|--- | --------------------

The Company has adopted SFAS
131, Disclosures about Segments of an Enterprise and Related Information which requires disclosure of financial and descriptive information about the Companys reportable operating segments. The operating segments reported below are
based on the nature of the products sold by the Company and are the segments of the Company for which separate financial information is available and for which operating results are regularly evaluated by executive management to make decisions about
resources to be allocated to the segment and assess its performance. Management evaluates segment performance based on segment gross profit. There were no material transfers between segments in the periods presented.

Historically, the Company disclosed three segments, but based on changes in organizational structure and strategic direction in 2008, the resulting
reporting of segments changed. The Company has conformed 2007 and 2006 segment information to be consistent with the current reporting and operating structure in place.

The Companys water transmission segment manufactures and markets large diameter, high-pressure steel pipe used primarily for water transmission. Water Transmission products are custom manufactured in accordance
with project specifications and are used primarily for high-pressure water transmission pipelines in the United States, Canada, and Mexico. Water Transmission manufacturing facilities are located in Portland, Oregon; Denver, Colorado; Adelanto,
California; Parkersburg, West Virginia; Saginaw, Texas; Pleasant Grove, Utah; and Monterrey, Mexico and products are sold primarily to public water agencies either directly or through an installation contractor.

The Companys tubular products segment manufactures and markets smaller diameter, electric resistance welded steel pipe for use in a wide range of
applications, including construction, agricultural, industrial, energy and traffic signpost systems. Tubular Products manufacturing facilities are located in Atchison, Kansas; Houston, Texas; and Bossier City, Louisiana. Tubular Products are
marketed through a network of direct sales force personnel and independent distributors throughout the United States, Canada and Mexico.
