Class Action and Derivative Lawsuits

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

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

The Richard action and the Plumbers action were consolidated on February 25, 2010. Plumbers and Pipefitters Local No. 630 Pension-Annuity Trust Fund was appointed lead plaintiff in the consolidated action. Defendants and lead plaintiff subsequently agreed that defendants did not need to respond immediately to either of the two outstanding complaints, and that a consolidated amended complaint would be filed within 45 days of the Company having completed the filing of the Quarterly Report on Form 10-Q for the quarter ended September 30, 2009 and the Annual Report on Form 10-K for the year ended December 31, 2009 with the SEC. A consolidated amended complaint was filed by the plaintiff on December 21, 2010, and our motion to dismiss was filed on February 25, 2011, as were similar motions filed by the individual defendants. Briefing on those motions concluded on May 24, 2011. On August 26, 2011, the Court denied all defendants' motions to dismiss, and the Company filed its answer to the consolidated amended complaint on October 24, 2011. The parties have conducted limited discovery and participated in an initial settlement mediation on January 30, 2012, with additional sessions anticipated in the future. By agreement of the parties, no further discovery will take place until after the mediation process is exhausted. The Company intends to vigorously defend itself against these claims. This securities litigation is at an early stage and, at this time, it is not possible to predict its outcome. Therefore, the Company has not accrued any charges related to this litigation.

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

On September 23, 2011, the Company was served with a derivative complaint, captioned Grivich v. Dunham, et al., No. 11-2-03678-6 ("Grivich"), and filed in the Superior Court of Washington for Clark County. The plaintiff in this action is allegedly a current shareholder of the Company. The Company is a nominal defendant in this litigation. Plaintiff seeks to assert, on the Company's behalf, claims against Brian W. Dunham, Stephanie J. Welty, William R. Tagmyer, Keith R. Larson, Wayne B. Kingsley, Richard A. Roman, Michael C. Franson and Neil R. Thornton. The asserted basis of the claims is that defendants breached fiduciary duties to the Company between April 2, 2007 and the date of the Complaint. Plaintiff seeks to recover, on the Company's behalf, damages for losses caused by the alleged wrongdoing.

On October 14, 2011, another derivative complaint, captioned Richard v. Dunham, et al., No. 11-2-04080-5 ("Richard Deriv."), was filed in the Superior Court of Washington for Clark County. The plaintiff in this action is allegedly a current shareholder of the Company. The Company is a nominal defendant in this litigation. Plaintiff seeks to assert, on the Company's behalf, claims against Brian W. Dunham, Stephanie J. Welty, William R. Tagmyer, Keith R. Larson, Wayne B. Kingsley, Richard A. Roman, Michael C. Franson and Neil R. Thornton. The asserted basis of the claims is that defendants breached fiduciary duties to the Company between April 2, 2007 and the date of the Complaint. Plaintiff seeks to recover, on the Company's behalf, damages for losses caused by the alleged wrongdoing.

An amended complaint in the Ruggles action was filed on November 10, 2011, and the defendant responded to the complaint by filing a motion to dismiss, which motion is still pending. The derivative parties participated in the initial settlement mediation described above and will participate in any follow up sessions. It should also be noted that derivative claims by their nature do not seek to recover damages from the Company, but purport instead to seek to recover damages for the benefit of the Company. These cases are at a very early stage and, at this time, it is not possible to predict their outcome. Therefore, the Company has not accrued any charges related to them.

SEC Investigation

On March 8, 2010, the staff of the Enforcement Division of the SEC advised our counsel that they had obtained a formal order of investigation with respect to matters related to the Audit Committee investigation. We are cooperating fully with the SEC in connection with these matters. We cannot predict if, when or how they will be resolved or what, if any, actions we may be required to take as part of any resolution of these matters. Any action by the SEC or other governmental agency could result in civil or criminal sanctions against us and/or certain of our current and former officers, directors and employees. It is not possible to predict the outcome of the investigation at this time. Therefore, we have not accrued any charges related to this investigation.

Other Matters

On December 1, 2000, a section of the lower Willamette River known as the Portland Harbor was included on the National Priorities List at the request of the U.S. Environmental Protection Agency (the "EPA"). While the Company's Portland, Oregon manufacturing facility does not border the Willamette River, an outfall from the facility's stormwater system drains into a neighboring property's privately owned stormwater system and slip. Since the listing of the site, the Company was notified by the EPA and the Oregon Department of Environmental Quality (the "ODEQ") of potential liability under the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"). In 2008, the Company was asked to file information disclosure reports with the EPA (CERCLA 104 (e) information request). By agreement with the EPA, the ODEQ is responsible for overseeing remedial investigation and source control activities for all upland sites to investigate sources and 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 potentially responsible parties known as the Lower Willamette Group (the "LWG"). The Company made a payment of $175,000 to the LWG in June 2007 as part of an interim settlement, and is under no obligation to make any further payment. A draft remedial investigation report was submitted to the EPA by the LWG in the fall of 2009; the final draft remedial investigation was submitted to the EPA in fall of 2011. The draft feasibility study was submitted in March 2012.

In 2001, groundwater containing elevated volatile organic compounds ("VOCs") was identified in one localized area of leased property adjacent to the Portland facility furthest from the river. Assessment work in 2002 and 2003 to further characterize the groundwater was consistent with the initial conclusion that the source of the VOCs is located off of Company-owned property. In February 2005, the Company entered into a Voluntary Agreement for Remedial Investigation and Source Control Measures ("Agreement") with the ODEQ. The Company is one of many Upland Source Control Sites working with the ODEQ on Source Control and is considered a "medium" priority site by ODEQ. The Company performed Remedial Investigation work required under the Agreement and submitted a draft Remedial Investigation/Source Control Evaluation Report in December 2005. The conclusions of the report indicated that the VOCs found in the groundwater do not present an unacceptable risk to human or ecological receptors in the Willamette River. The report also indicated there is no evidence at this time showing a connection between detected VOCs in groundwater and Willamette River sediments. In 2009, the ODEQ requested that the Company revise its Remedial Investigation/Source Control Evaluation Report from 2005 to include recent information from focused supplemental sampling at the Portland facility and more recent information that has become available related to nearby properties. The Company expects to submit an Expanded Risk Assessment for the VOC's in Groundwater following the completion of a paving project at the Portland facility.

Also, based on sampling associated with the Portland facility's remedial investigation and on sampling and reporting required under the Portland, Oregon manufacturing facility's National Pollutant Discharge Elimination System permit for storm water, the Company and the ODEQ have periodically detected low concentrations of polynuclear aromatic hydrocarbons ("PAHs"), polychlorinated biphenyls ("PCBs"), and trace amounts of zinc in storm water. Storm water from the Portland, Oregon manufacturing facility site is discharged into a communal storm water system that ultimately discharges into the neighboring property's privately owned slip. The slip was historically used for shipbuilding and subsequently for ship breaking and metal recycling. Studies of the river sediments have revealed concentrations of PAHs, PCBs and zinc, along with other constituents which are common constituents in urban storm water discharges. To minimize the zinc traces in its storm water, the Company painted a substantial part of the Portland facility's roofs. In June 2009, under the ODEQ Agreement, the Company submitted a Final Supplemental Work Plan to evaluate and assess soil and storm water, and further assess groundwater risk. In May 2010, the Company submitted a remediation plan related to soil contamination, which ODEQ approved in August 2010. Since August 2010, the Company has been engaged in performing the approved remediation plan which has included an upgrade to the fuel and waste storage systems (completed in the fourth quarter of 2011) and a storm water filtration system (completed in the first quarter of 2012). The remediation plan also required the excavation of a localized soil area to remove soil containing PAHs (completed in the third quarter of 2011). During the localized soil excavation in the third quarter of 2011, additional stained soil was discovered, and at the request of ODEQ, the Company developed an additional Work Plan to characterize the nature and extent of soil and/or groundwater impacts from the staining. The Company plans to implement this Work Plan in the second and third quarter of 2012. The Company expects to spend approximately $1.7 million in 2012 to complete the work specified in the Work Plans.

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

The Trustees have encouraged potentially responsible parties to voluntarily participate in the funding of their injury assessments and several of those parties have agreed to do so. In 2009, one of the Tribal Trustees (the Yakima Nation) resigned and has requested funding from the same parties to support its own assessment. The Company has not assumed any payment obligation or liability related to either request. The extent of the Company's obligation with respect to Portland Harbor matters is not known, and no further adjustment to the consolidated financial statements has been recorded as of March 31, 2012.

We operate our facilities under numerous governmental permits and licenses relating to air emissions, storm water run-off, and other environmental 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.

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 $3.2 million at March 31, 2012. The stand-by letters of credit relate to workers' compensation insurance and equipment financing.
