INTRODUCTION

General

        This Proxy Statement and the accompanying 2001 Annual Report to Shareholders are being furnished to the shareholders of Northwest Pipe Company, an Oregon corporation (the "Company"), as part of the solicitation of proxies by the Company's Board of Directors (the "Board of Directors") for use at the Company's annual meeting of shareholders (the "Annual Meeting") to be held on Thursday, May 23, 2002 at the Heathman Hotel, 1001 SW Broadway, Portland, OR 97205, at 9:00 a.m., local time. At the Annual Meeting, shareholders will be asked to elect two members to the Board of Directors and to transact such other business as may properly come before the Annual Meeting or any adjournments or postponements thereof. This Proxy Statement, together with the enclosed proxy card and the 2001 Annual Report to Shareholders, are first being mailed to shareholders of the Company on or about April 25, 2002.

Solicitation, Voting and Revocability of Proxies

        The Board of Directors has fixed the close of business on March 15, 2002 as the record date for the determination of the shareholders entitled to notice of and to vote at the Annual Meeting. Accordingly, only holders of record of shares of Common Stock at the close of business on such date will be entitled to vote at the Annual Meeting, with each such share entitling its owner to one vote on all matters properly presented at the Annual Meeting. On the record date, there were approximately 1,700 beneficial owners of the 6,537,053 shares of Common Stock then outstanding. The presence in person or by proxy of a majority of the total number of outstanding shares of Common Stock entitled to vote at the Annual Meeting is necessary to constitute a quorum at the Annual Meeting.

        If the enclosed form of proxy is properly executed and returned in time to be voted at the Annual Meeting, the shares represented thereby will be voted in accordance with the instructions marked thereon. Executed but unmarked proxies will be voted FOR the election of the two nominees for election to the Board of Directors. The Board of Directors does not know of any matters other than those described in the Notice of Annual Meeting that are to come before the Annual Meeting. If any other matters are properly brought before the Annual Meeting, the persons named in the proxy will vote the shares represented by such proxy upon such matters as determined by a majority of the Board of Directors.

        Shareholders who execute proxies retain the right to revoke them at any time prior to the exercise of the powers conferred thereby by filing a written notice of revocation with, or by delivering a duly executed proxy bearing a later date to, Corporate Secretary, Northwest Pipe Company, 200 Market Street, Suite 1800, Portland, Oregon 97201-5730, or by attending the Annual Meeting and voting in person. All valid, unrevoked proxies will be voted at the Annual Meeting.

ELECTION OF DIRECTORS

        At the Annual Meeting, two directors will be elected, each for a three-year term. Unless otherwise specified on the proxy, it is the intention of the persons named in the proxy to vote the shares represented by each properly executed proxy for the election of the nominees named below. The Board of Directors believes that the nominees will stand for election and will serve if elected as directors. However, if any of the persons nominated by the Board of Directors fails to stand for election or is unable to accept election, the proxies will be voted for the election of such other person as the Board of Directors may recommend.

        The Company's Articles of Incorporation and Bylaws provide that the Board of Directors shall be composed of not less than six (6) and not more than nine (9) directors. The Board of Directors has fixed the number of directors at seven (7). The Company's directors are divided into three classes. The term of office of only one class of directors expires each year, and their successors are elected for terms of three years, and until their successors are elected and qualified. There is no cumulative voting for election of directors.

The potential realizable value is calculated based on the term of the option at time of grant (10 years) and is calculated by assuming that the stock price on the date of grant appreciates at the indicated annual rate compounded annually for the entire term of the option and that the option is exercised and sold on the last day of its term for the appreciated price. Actual gains, if any, on stock option exercises are dependent on the future performance of the Common Stock and overall stock market conditions

Change in Control Agreements

        The Company has entered into change in control agreements (the "Agreements") with its executive officers, including the named executive officers. Each of the Agreements was originally for a term ending July 19, 2001, provided that on that date and each anniversary thereafter, the term of the Agreements will be automatically extended by one year unless either party gives 90 days prior written notice that the term of an agreement shall not be so extended. If a "Change in Control" (as defined in the Agreements and described below) occurs during the term of Agreements, the Agreements will continue in effect until two years after the Change in Control.

        If an executive officer's employment with the Company is terminated within two years after a Change in Control either by the Company without "Cause" (as defined in the Agreements and described below) or by the executive officer for "Good Reason" (as defined in the Agreements and described below), the executive officer will be entitled to receive his full base salary through the date of termination and any benefits or awards (both cash and stock) that have been earned or are payable through the date of termination plus (i) a lump sum payment equal to two year's base salary (three years in the case of Messrs. Tagmyer and Dunham) and (ii) an amount equal to two times (three times in the case of Messrs. Tagmyer and Dunham) the average cash bonuses paid to the executive officer during the previous three years. In addition, the executive officer would be entitled to the continuation of health and insurance benefits for certain periods and all outstanding unvested stock options would immediately become fully vested. In the event that the payments made to an executive officer would be deemed to be a "parachute payment" under the Internal Revenue Code of 1986, an executive officer may choose to accept payment of a reduced amount that would not be deemed to be a "parachute payment."

        If an executive officer's employment with the Company is terminated within two years after a Change in Control either by the Company for Cause or as a result of the executive officer's disability or death, the executive officer will be entitled to receive his full base salary through the date of termination plus any benefits or awards (both cash and stock) that have been earned or are payable through the date of termination.

        For purposes of the Agreements, a "Change in Control" includes (i) any merger or consolidation transaction in which the Company is not the surviving corporation, unless shareholders of the Company immediately before such transaction have the same proportionate ownership of common stock of the

7



surviving corporation in the transaction, (ii) the acquisition by any person of 30 percent or more of the Company's total combined voting power, (iii) the liquidation of the Company or the sale or other transfer of substantially all of its assets, and (iv) a change in the composition of the Board of Directors during any two-year period such that the directors in office at the beginning of the period and/or their successors who were elected by or on the recommendation of two-thirds of the directors in office at the beginning of the period do not constitute at least a majority of the Board. For purposes of the Agreements, "Good Reason" includes (i) an adverse change in the executive officer's status, title, position(s) or responsibilities or the assignment to the executive of duties or responsibilities which are inconsistent with the executive officer's status, title or position, (ii) a reduction in the executive officer's base salary or the failure to pay compensation otherwise due to the executive officer, (iii) a requirement that the executive officer be based anywhere other than within 10 miles of his job location before the Change in Control, (iv) the Company's failure to continue in effect any compensation or employee benefit plan or program in effect before the Change in Control or any act or omission that would adversely effect the executive officer's continued participation in any such plan or program or materially reduce the benefits under such plan or program, (v) the failure by the Company to require any successor to the Company to assume the Company's obligations under the Agreements within 30 days after a Change in Control. For purposes of the Agreements, "Cause" means the willful and continued failure to satisfactorily perform the duties assigned to the executive officer within a certain period after notice of such failure is given and commission of certain illegal conduct.

Employment Agreement

        The Company entered into an Employment Agreement (the "Employment Agreement") with Mr. Tagmyer effective November 14, 2000. The Employment Agreement is for a term ending on December 31, 2010, unless terminated earlier by the parties. During calendar years 2001, 2002 and 2003, the Employment Agreement provides that Mr. Tagmyer will receive a base salary of $350,000, will be eligible for annual bonuses in an amount, if any, determined by the Board and will be entitled to all fringe benefits to which he was entitled before the date of the Employment Agreement. During calendar years 2004 through 2010, Mr. Tagmyer will receive a base salary of $150,000 per year. If the Employment Agreement is terminated by Mr. Tagmyer or by the Company for "cause" (as defined), Mr. Tagmyer would be paid all compensation and expenses to which he is entitled through the date of termination of the Employment Agreement. If the Employment Agreement is terminated by the Company for any reason other than for "cause" or as a result of Mr. Tagmyer's death, Mr. Tagmyer would be entitled to receive all of the remaining payments that he would have been entitled to receive under the Employment Agreement if it had not been terminated. If the Employment Agreement is terminated as a result of Mr. Tagmyer's death, Mr. Tagmyer's beneficiary or estate would be entitled to receive fifty percent of the remaining payments under the Employment Agreement to which Mr. Tagmyer would have been entitled had he survived. If the Employment Agreement is terminated by the Company for any reason other than "cause" or Mr. Tagmyer's death or disability at a time when Mr. Tagmyer's Change in Control Agreement remains in effect and would apply to such termination, Mr. Tagmyer will be permitted to elect whether to accept the benefits payable under the Employment Agreement or the benefits payable under the Change in Control Agreement. The Employment Agreement contains certain noncompetition provisions that apply to Mr. Tagmyer's activities during the term of the Employment Agreement and for a period of one year after the later of the date of termination of the Agreement or the date the last payment is made under the Agreement.

In addition, each nonemployee member of the Board of Directors receives a $12,000 annual retainer, $1,000 for each Board meeting attended, $500 for each telephonic Board meeting attended and $500 for each meeting of a committee of the Board attended. The Company's 1995 Stock Option Plan for Nonemployee Directors (the "1995 Nonemployee Director Plan") provides that an option to purchase 5,000 shares of Common Stock is granted to each new nonemployee director at the time such person is first elected or appointed to the Board of Directors. In addition, each nonemployee director receives an option to purchase 2,000 shares of Common Stock annually after each annual meeting of shareholders. The number of options which may be granted under the 1995 Nonemployee Director Plan in any fiscal year may not exceed 20,000, subject to stock splits and similar events, and a total of 100,000 shares of Common Stock have been reserved for issuance upon exercise of stock options granted under the 1995 Nonemployee Director Plan. On May 15, 2001 options to purchase 2,000 shares of Common Stock, at $14.000 each, were granted to each of Messrs. Franson, Kingsley, Kearns, Ryles and Thornton.

COMPENSATION COMMITTEE REPORT

        Under rules established by the Securities and Exchange Commission (the "SEC"), the Company is required to provide certain data and information with regard to the compensation and benefits provided to the Company's Chief Executive Officer and the four other most highly compensated executive officers. In fulfillment of this requirement, the Compensation Committee has prepared the following report for inclusion in this Proxy Statement.

Executive Compensation Philosophy

        The Compensation Committee is composed entirely of nonemployee, outside directors and is responsible for setting and monitoring policies governing compensation of executive officers. The Compensation Committee reviews the performance and compensation levels for executive officers, and sets salary and bonus levels and option grants under the Company's stock option plans. The objectives of the Committee are to correlate executive compensation with the Company's business objectives and performance and to enable the Company to attract, retain and reward executive officers who contribute to the long-term success of the Company.

        The Omnibus Budget Act of 1993 added Section 162(m) to the Internal Revenue Code of 1986, which limits to $1,000,000 the deductibility of compensation (including stock-based compensation) individually paid to a publicly-held Company's chief executive officer and the four other most highly compensated executive officers. The Board of Directors and the Compensation Committee intend to take the necessary steps to structure executive compensation policies to comply with this limit on deductibility of executive compensation.

        Salaries.    The Compensation Committee annually assesses the performance and sets the salary of the Company's executive officers. Salaries for executive officers are based on a review of salaries for similar positions requiring similar qualifications. In determining executive officer salaries, the Compensation Committee reviews recommendations from management which include information from salary surveys. Additionally, the Compensation Committee establishes both financial and operational based objectives and goals. These goals and objectives include sales and spending forecasts, along with published executive compensation literature for comparable sized companies. The Compensation Committee considers not only the performance evaluations of executive officers but also reviews the financial condition of the Company in setting salaries.

        Bonus Awards.    The Compensation Committee administers a cash bonus plan to provide additional incentives to executive officers and certain other management employees. As of the date of this Proxy Statement, the Board of Directors has not approved the executive bonus plan for 2001 and no bonus awards for 2001 have been made.

        Stock Options.    The Compensation Committee believes that employee equity ownership provides significant motivation to executive officers to maximize value for the Company's shareholders and, therefore, periodically grants stock options under the Company's stock option plans. Stock options are granted at the current market price and will only have value if the Company's stock price increases over the exercise price. The Compensation Committee determines the size and frequency of option grants for executive officers, after consideration of recommendations from the Chief Executive Officer. Recommendations for option grants are based upon the relative position and responsibilities of each executive officer, expected contributions of each officer to the Company and previous option grants to such executive officers.

        Chief Executive Officer Compensation.    Mr. Dunham's 2001 base salary was determined in the same manner as the other executives as described in Salaries above. The Compensation Committee approved Mr. Dunham's 2001 annual base salary of $368,756, based on the salary survey data referred to above and compensation levels of Chief Executive Officers of comparable size companies in industries similar

10



to the Company's. As described in Bonus Awards above, the executive bonus plan for 2001 has not been approved and no bonus awards for 2001 have been made.


AUDIT COMMITTEE REPORT

        The Audit Committee of the Board of Directors is comprised of three directors who are considered independent under applicable Nasdaq Stock Market rules. The Committee operates under a written charter adopted by the Board.

        The primary purpose of the Audit Committee is to oversee the Company's financial reporting process on behalf of the Board and report the results of its activities to the Board. The Audit Committee annually reviews and recommends to the Board the selection of the Company's independent accountants.

        Recent business failures and the downturn in the general economy have reemphasized the importance of the responsibilities of the Audit Committee. The SEC and American Institute of Certified Public Accountants ("AICPA") have indicated the need for the Audit Committee to increase its attention to the Company's disclosures in the annual report. The scope of the audit of the Company's 2001 financial statements included matters the SEC and AICPA have designated for increased attention. Additional emphasis was focused on off- and on-balance sheet financing arrangements, related party transactions, internal controls, cross-credit links, pension plans and critical accounting policies. More in-depth discussions were held between the auditors and management on the risks, significant estimates and judgments, trends, events or uncertainties that were the basis for the financial reports.

        Management is responsible for preparing the Company's financial statements. The independent accountants are responsible for performing an independent audit of the Company's audited financial statements in accordance with generally accepted auditing standards and to issue a report thereon. The Committee's responsibility is to monitor and oversee these processes. In performing this function, the Audit Committee acts only in an oversight capacity. The Committee relies on the work and the assurances of the Company's management, which has the primary responsibility for financial statements and reports, and of the independent auditors, who, in their report express an opinion on the conformity of the Company's annual financial statements to generally accepted accounting principles.

        In this context, the Committee has reviewed and discussed the audited financial statements with management and the independent accountants. The Committee also has discussed with the independent accountants the matters required to be discussed by Statement on Auditing Standards No. 61 (Communication with Audit Committees).

        The Company's independent accountants also provided to the Committee the written disclosures and letter required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), and the Committee discussed with the independent accountant's that firm's independence.

        Based on the above discussions and review with management and the independent accountants, the Committee recommended to the Board of Directors that the audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2001 for filing with the Commission.

        Respectfully submitted by the Audit Committee of the Board of Directors.

Section 16(a) Beneficial Ownership Reporting Compliance

        Section 16(a) of the Securities Exchange Act of 1934, as amended requires the Company's directors and executive officers and persons who own more than ten percent of a registered class of the Company's equity securities, to file initial reports of ownership and reports of changes in ownership of shares with the Securities and Exchange Commission. Such persons also are required to furnish the Company with copies of all Section 16(a) reports they file.

        Based solely on its review of the copies of such reports received by it with respect to 2001, or written representations from certain reporting persons, the Company believes that all filing requirements applicable to its directors, officers and persons who own more than ten percent of a registered class of the Company's equity securities have been complied with for 2001.
