A-1 ii (WABASH NATIONAL LOGO) WABASH NATIONAL CORPORATION 1000 SAGAMORE PARKWAY SOUTH LAFAYETTE, INDIANA 47905 PROXY STATEMENT ANNUAL MEETING OF STOCKHOLDERS ON MAY 18, 2006 This Proxy Statement is furnished on or about April 17, 2006, to stockholders of Wabash National Corporation (hereinafter, "we" "us" and "Wabash"), 1000 Sagamore Parkway South, Lafayette, Indiana 47905, in connection with the solicitation by our Board of Directors of proxies to be voted at the Annual Meeting of Stockholders to be held at our offices located at 3000 East Main Street, Lafayette, Indiana 47905, on Thursday, May 18, 2006, at 10:00 a.m. local time, (the "Annual Meeting") and at any adjournments or postponements of the Annual Meeting. ABOUT THE MEETING WHAT IS THE PURPOSE OF THE ANNUAL MEETING? At the Annual Meeting, stockholders will act upon the matters outlined in the accompanying Notice of Annual Meeting of Stockholders. In addition, our management will report on our performance during fiscal 2005 and respond to questions from our stockholders. WHO IS ENTITLED TO VOTE? Only stockholders of record at the close of business on April 3, 2006 (the "Record Date"), are entitled to receive notice of the Annual Meeting and to vote the shares of Common Stock that they held on the Record Date at the Annual Meeting, or any postponement or adjournment of the Annual Meeting. Each share entitles its holder to cast one vote on each matter to be voted upon. A list of stockholders of record as of the Record Date will be available for inspection during ordinary business hours at our offices located at 1000 Sagamore Parkway South, Lafayette, Indiana 47905, from May 8, 2006 to the date of our Annual Meeting. The list will also be available for inspection at the Annual Meeting. WHO CAN ATTEND THE ANNUAL MEETING? All stockholders as of the close of business on the Record Date, or their duly appointed proxies, may attend the Annual Meeting. Please note that if you hold your shares in "street name" (that is, through a broker or other nominee), you will need to bring a copy of a brokerage statement reflecting your stock ownership as of the Record Date and check in at the registration desk at the Annual Meeting. Alternatively, in order to vote, you may contact the person in whose name your shares are registered and obtain a proxy from that person and bring it to the Annual Meeting. WHAT CONSTITUTES A QUORUM? The presence at the Annual Meeting, in person or by valid proxy, of the holders of a majority of the shares of our Common Stock outstanding on the Record Date will constitute a quorum, permitting us to conduct our business at the Annual Meeting. As of the Record Date, 31,567,158 shares of Common Stock, held by 1,119 stockholders of record, were outstanding and entitled to vote at the Annual Meeting. Proxies received but marked as abstentions and broker non-votes will be included in the calculation of the number of shares considered to be present at the Annual Meeting. HOW DO I VOTE? You can vote on matters to come before the Annual Meeting in the following two ways: - You can attend the Annual Meeting and cast your vote in person; or - You can vote by completing, dating and signing the enclosed proxy card and returning it in the enclosed postage-paid envelope. If you do so, you will authorize the individuals named on the proxy card, referred to as the proxies, to vote your shares according to your instructions. If you provide no instructions, the proxies will vote your shares according to the recommendation of the Board of Directors or, if no recommendation is given, in their own discretion. WHAT IF I VOTE AND THEN CHANGE MY MIND? You may revoke your proxy at any time before it is exercised by: - Sending written notice of revocation addressed to the Corporate Secretary, Wabash National Corporation, P.O. Box 6129, Lafayette, Indiana 47903; or - Sending in another duly executed proxy bearing a later date; or - Attending the Annual Meeting and casting your vote in person. Your last vote will be the vote that is counted. WHAT ARE THE BOARD'S RECOMMENDATIONS? The Board recommends that you vote FOR election of the nominated slate of Directors (see page 5). Unless you give other instructions on your proxy card, the persons named as proxy holders on the proxy card will vote in accordance with the Board's recommendation. With respect to any other matter that properly comes before the meeting, the proxy holders will vote in their own discretion. WHAT VOTE IS REQUIRED? Election of Directors. The election of Directors requires a plurality of the votes cast for the election of Directors; accordingly, the nine directorships to be filled at the Annual Meeting will be filled by the nine nominees receiving the highest number of votes. A properly executed proxy marked "WITHHOLD AUTHORITY" with respect to the election of one or more Directors will not be voted with respect to the nominee or nominees indicated, although it will be counted for purposes of determining whether there is a quorum. A broker "non-vote," discussed below, will also have no effect on the outcome since only a plurality of votes actually cast is required to elect a Director. Effect of Broker Non-Vote. If you hold your shares in "street name" through a broker or other nominee, your broker or nominee may elect to exercise voting discretion with respect to the election of Directors. Under New York Stock Exchange Rules, the proposal to elect Directors is considered a "discretionary" item. This means that 2 brokerage firms may vote in their discretion on this matter on behalf of clients who have not furnished voting instructions at least 15 days before the date of the Annual Meeting. However, if you do not give your broker or nominee specific instructions, your broker or nominee may elect not to exercise its discretion, and in which case your shares will not be voted on this matter. Shares represented by such broker "non-votes" will not be counted in determining the number of shares necessary for approval of such matters; however, such shares will be counted in determining whether there is a quorum. WHO WILL BEAR THE COSTS OF THIS PROXY SOLICITATION? We will bear the cost of solicitation of proxies. This includes the charges and expenses of brokerage firms and others for forwarding solicitation material to beneficial owners of our outstanding Common Stock. We may solicit proxies by mail, personal interview, telephone or via the Internet through our officers, Directors and other management employees, who will receive no additional compensation for their services. PROPOSAL 1 ELECTION OF DIRECTORS Our Bylaws provide that our Board of Directors shall be comprised of not less than three nor more than nine Directors, with the exact number to be fixed by resolution of the Board of Directors. The Board has currently fixed the authorized number of Directors at nine. At the Annual Meeting, nine Directors are to be elected, each of whom shall serve for a term of one year or until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal. Proxies representing shares held on the Record Date which are returned duly executed will be voted, unless otherwise specified, in favor of the nine nominees for the Board of Directors named below. Each of the nominees has consented to be named herein and to serve on the Board if elected. It is not anticipated that any nominee will become unable or unwilling to accept nomination or election, but, if that should occur, the persons named in the proxy intend to vote for the election in his or her stead, such other person as the Nominating and Corporate Governance Committee may recommend to the Board. HAS WABASH ADOPTED CORPORATE GOVERNANCE GUIDELINES AND A CODE OF ETHICS? Our Board of Directors has adopted Corporate Governance Guidelines (the "Guidelines") and a Code of Business Conduct and Ethics (the "Code of Ethics"). The Guidelines set forth a framework within which the Board of Directors oversees and directs the affairs of Wabash. The Guidelines cover, among other things, the composition and functions of the Board of Directors, Director independence, stock ownership by our Directors, management succession and review, Board committees, the selection of new Directors, and Director responsibilities and duties. The Code of Ethics covers, among other things, compliance with laws, rules and regulations (including insider trading), conflicts of interest, corporate opportunities, confidentiality, protection and use of company assets, and the reporting process for any illegal or unethical conduct. The Code of Ethics is applicable to all of our officers, Directors and employees, including our Chief Executive Officer and our Chief Financial Officer. The Code of Ethics includes provisions which are specifically applicable to our Chief Financial Officer and senior financial officers (as defined in the Code of Ethics). The Guidelines and Code of Ethics are each available on the About Us page of our website at www.wabashnational.com and are available in print without charge by writing to: Wabash National Corporation, Attention: Corporate Secretary, P.O. Box 6129, Lafayette, Indiana 47903. Any waiver of the Code of Ethics for our executive officers or Directors may be made only by our Board of Directors or a Board committee and will be promptly disclosed as required by law or the listing standards of the New York Stock Exchange. If we amend our Code of Ethics or waive the Code of Ethics with respect to our Chief Executive Officer, principal financial officer or principal accounting officer, we will post the amendment or waiver on our website. 3 ARE THE DIRECTORS AND DIRECTOR NOMINEES INDEPENDENT? Under the rules of the New York Stock Exchange, the Board must affirmatively determine that a Director has no material relationship with us in order for the Director to be considered independent. As permitted by the New York Stock Exchange rules, to assist the Board in making this determination, our Board of Directors has adopted categorical standards of independence. The Board has determined that relationships are not material and would not impair a Director's independence when the aggregate amount of payments by us to, and to us from, any company of which a Director is an executive officer or employee or of which a family member of a Director is an executive officer, are less than the greater of $1 million or 2% of such other company's consolidated gross revenues in any single fiscal year. Our Board of Directors undertook its annual review of Director independence in February 2006. During this review, the Board considered transactions and relationships between each Director and Director Nominee, and any member of his or her immediate family, and Wabash and its subsidiaries and affiliates. The Board also considered whether there were any transactions or relationships between Directors or Director Nominees or any member of their immediate families (or any entity of which a Director or Director Nominee or an immediate family member is an executive officer, general partner or significant equity holder) and members of our senior management or their affiliates. Finally, the Board considered charitable contributions to organizations with which Directors or Director Nominees had relationships. The purpose of this review was to determine whether any such relationship or transaction existed that was inconsistent with a determination that the Director or Director Nominee is independent. As a result of this review, the Board affirmatively determined that all of the Directors nominated for election at the Annual Meeting are independent of Wabash and its management within the meaning of the rules of the New York Stock Exchange and the categorical standard described above, with the exception of William P. Greubel and Richard J. Giromini. Each of Messrs. Greubel and Giromini is considered an inside Director because of his employment as a senior executive of the Company. Our independent Directors meet at least twice per year in executive session without management. Mr. Burdakin will act as chair of each executive session of the independent Directors following the date of the Annual Meeting, the effective date of Mr. Burdakin's appointment as our Lead Director. ARE THERE ANY DIRECTORS WHO ARE NOT STANDING FOR RE-ELECTION? Yes. John T. Hackett, Chairman of our Board of Directors, has notified the Board that he will resign as a Director effective as of the day of the Annual Meeting. Mr. Hackett has been a Director since 1991 and our Chairman since October 2001. In addition, effective May 12, 2005, Mr. Ludvik F. Koci resigned from the Board of Directors. Mr. Koci had served as a Director since December 1993. Both Mr. Hackett and Mr. Koci have been essential to our growth and success. Their sage advice and steadfast leadership will be missed. The Board of Directors has elected Mr. Greubel, our Chief Executive Officer and a Director, to replace Mr. Hackett as Chairman of the Board of Directors, effective upon Mr. Hackett's resignation. (THIS SPACE INTENTIONALLY LEFT BLANK) 4 WHO ARE THE DIRECTOR NOMINEES STANDING FOR ELECTION?

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION THE FOLLOWING REPORT OF THE COMPENSATION COMMITTEE DOES NOT CONSTITUTE SOLICITING MATERIAL AND SHOULD NOT BE DEEMED FILED OR INCORPORATED BY REFERENCE INTO ANY OTHER FILING BY US UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES EXCHANGE ACT OF 1934, EXCEPT TO THE EXTENT WE SPECIFICALLY INCORPORATE THIS REPORT. The Compensation Committee has furnished the following report on executive compensation for fiscal 2005. During 2005, decisions on cash compensation and equity compensation for our executive officers, including stock options and restricted stock grants, were made by the Compensation Committee of the Board of Directors. Our General Philosophy on Executive Compensation. Our executive compensation policies toward our executive officers are intended to provide competitive levels of compensation that reflect our annual and long-term performance goals, reward superior corporate performance, and assist us in attracting and retaining qualified executives. Total compensation for our executive officers is comprised of three principal components: base salary, annual incentive compensation and long-term compensation tied to our Common Stock. Base Salary. Each year the Compensation Committee determines the base salaries of each of the executive officers and that of the Chief Executive Officer based on available competitive compensation data, the Compensation Committee's assessment of each officer's past performance and its expectation as to future contributions. Annual Bonus Plan. The amounts of annual bonuses paid to the executive officers under our bonus program (the "Bonus Plan") depend primarily upon whether, and the extent to which, we or the executive officer, as appropriate, achieve certain pre-established working capital, profit targets, and personal performance objectives. Under the Bonus Plan, we have established for each participant a percentage of his annual base salary that is to be the target payout. The Compensation Committee reviews the target amount and the performance metrics each year and changes are made when deemed necessary. Generally, if we achieve our specific performance metrics objectives, each Bonus Plan participant will receive a bonus for the year that is equal to plan targets. If our performance exceeds target performance, payouts can exceed target payout levels. Target payouts range from 15% to 100% of base salary. After the bonus payouts are computed for each Bonus Plan participant, they are subject to review and approval by the Compensation Committee. Bonuses are paid to participants in the calendar year following the year in which bonuses are earned by the participants. 20 In addition, certain executive officers may receive bonus amounts pursuant to an executive employment agreement. Bonuses for 2003, 2004 and 2005 for each of the Named Officers appear under the caption "Bonus" in the "Summary Compensation Table" described in the proxy statement of which this report is a part. Long Term Compensation through Stock Option, Restricted Common Stock and Stock Appreciation Rights. Under our 2000 Stock Option and Incentive Plan and 2004 Stock Incentive Plan, options may be granted to our officers, Directors, other key employees, and those of our subsidiaries to purchase shares of Common Stock at a price not less than market price at the date of grant. Options granted under the 2000 Stock Option and Incentive Plan and the 2004 Stock Incentive Plan typically become exercisable in annual installments of three years, and options granted under our Amended 1992 Stock Option Plan, under which grants may no longer be made, typically become exercisable in annual installments of five years. Option grants to our non-employee Directors, however, are fully vested and exercisable six months after the date of grant. All options expire ten years after the date of grant. The 2000 Stock Option and Incentive Plan and 2004 Stock Incentive Plan provide for the award of restricted Common Stock to our Directors and officers and key employees and those of our subsidiaries. In 2004, the Compensation Committee began to reduce the portion of equity awards granted to officers as options and increased the use of restricted stock. The forfeiture restrictions applicable to restricted stock grants generally lapse ratably on the third, fourth and fifth anniversaries of the grant date. In 2001, we adopted a Stock Appreciation Rights Plan, under which stock appreciation rights may be granted to our officers and key employees and those of our subsidiaries. We have not made any grants in 2005 under the Stock Appreciation Rights Plan. Severance Agreements. We approved for our executives a change in control policy on December 8, 2005, that is applicable to our Chief Executive Officer, President and Chief Operating Officer, Senior Vice President - Chief Financial Officer, Senior Vice President - Sales and Marketing, and Senior Vice President - Human Resources. The initial term of the policy will be two years, during which time the policy will be irrevocable, and the policy will be renewable for subsequent one year terms. Benefits under the policy are payable in the event of a qualifying termination, which is a termination within twelve months after a change in control that is either by Wabash without cause or by the executive for good reason, unless the executive is entitled to greater benefits under the terms of an employment agreement. An executive must execute a release in favor of the Company to receive benefits under the policy. In the case of our Chief Executive Officer, and our and President and Chief Operating Officer, the benefits under the policy upon a qualifying termination are a severance payment of two times base salary plus two times the executive's target bonus. In addition, a payment will be made for a pro-rata portion of the executive's target bonus for the current year, and health benefits will be continued for two years (or until comparable coverage is obtained by the executive). In the case of our Senior Vice President and Chief Financial Officer, Senior Vice President - Sales and Marketing and Senior Vice President - Human Resources, the benefits under the policy upon a qualifying termination of employment are a severance payment of one and one-half times base salary plus one and one-half times the executive's target bonus. In addition, a payment will be made for a pro-rata portion of the executive's target bonus for the current year, and health benefits will be continued for one and one-half years (or until comparable coverage is obtained by the executive). Further detail on severance arrangements with Messrs. Greubel and Giromini is contained in the description of our employment agreements with these individuals described elsewhere in the proxy statement of which this report is a part. Chief Executive Officer's 2005 Compensation. Our Chief Executive Officer generally participates in the same executive compensation plans and arrangements available to the other senior executives. Accordingly, the compensation of the Chief Executive Officer consists of annual base salary, annual bonus and grants of options and restricted stock. The Compensation Committee's general approach in setting compensation of the Chief Executive Officer is to be competitive with other companies in the industry, but to have a large portion of compensation based upon our performance. 21 Mr. Greubel's compensation is based on a negotiated employment agreement entered into in April 2002 between Mr. Greubel and us and it provides for a base salary of $600,000 per year, which has now been increased to a base salary of $710,000, and a bonus that is targeted at 50% of his base salary, but which has been increased to 100% of his base salary and may range from 0% to 100% of his base salary. This agreement is described in further detail elsewhere in the proxy statement of which this report is a part. In negotiating Mr. Greubel's compensation, the Board of Directors considered the criteria contained in this report, his qualifications and experience, his previous compensation levels, foregone awards and other compensation at his prior employer, and the competitive marketplace for executive talent. In addition, it considered that a substantial initial equity award in the form of an option was warranted and necessary in order to attract an executive such as Mr. Greubel, and to provide him a strong incentive to increase stockholder value. As a result of Mr. Greubel's individual performance, we raised his base salary to $710,000 and increased his bonus target to 100% of his base salary effective March 1, 2006, and granted him an option to purchase 25,360 shares of our Common Stock along with 25,110 restricted stock units. In keeping with the philosophy of granting equity awards for the purpose of encouraging executive officers to focus on long-term stockholder returns and for the purpose of encouraging the retention of key executives, the forfeiture restrictions on the restricted stock granted in 2005 begin to lapse after three years and do not fully lapse until the fifth anniversary of the date of grant. The Compensation Committee has determined that Wabash did not meet the performance threshold targets for fiscal year 2005 established by the Committee under the Bonus Plan. However, in light of our performance and that of our management and employees during 2005, the Committee approved a performance-based discretionary bonus award for our employees, including our Named Officers. Our Board approved and ratified the performance-based award to our executive officers in February 2006. Pursuant to the performance-based discretionary bonus, Mr. Greubel was awarded a bonus of $122,400. Mr. Greubel's 2005 bonus reflects Wabash's performance with respect to certain working capital, profit and specific strategic objectives established by the Compensation Committee for the 2005 fiscal year, as well as Mr. Greubel's individual performance and leadership. Section 162(m). Under Section 162(m) of the Internal Revenue Code of 1986, as amended, and applicable Treasury regulations, no tax deduction is allowed for annual compensation in excess of $1 million paid to the five most highly compensated executive officers. Performance-based compensation that has been approved by stockholders, however, is excluded from the $1 million limit if, among other requirements, the compensation is payable only upon attainment of pre-established, objective performance goals and the board committee that establishes such goals consists only of "outside directors" as defined for purposes of Section 162(m). For 2005, all of the members of the Compensation Committee qualified as "outside directors." The Compensation Committee considers the impact of Section 162(m) when making its compensation decisions, however, the Compensation Committee's primary focus is on the most appropriate methods and approaches for the design and delivery of compensation to our executive officers. The 2004 Stock Incentive Plan is structured to qualify as "performance-based" and to satisfy the stockholder approval and outside director administration requirements of Section 162(m). Accordingly, compensation awarded by the Compensation Committee to any of the five most highly compensated executive officers under the 2004 Stock Incentive Plan would be deductible under Section 162(m).

Stewart 22 EMPLOYMENT AND SEVERANCE AGREEMENTS Except for employment agreements we have entered into with Mr. Greubel and Mr. Giromini, we do not have employment contracts with our executive officers. In April 2002, we entered into an employment agreement with Mr. Greubel, pursuant to which Mr. Greubel serves as our Chief Executive Officer, commencing April 12, 2002 through March 31, 2005. The term of Mr. Greubel's employment automatically renews for successive one-year periods unless and until either party provides written notice, not less than 60 days prior to the end of the then current term, of his or its intent not to renew the agreement. Neither party provided the other with notice of the intent not to renew this agreement prior to March 31, 2006; therefore, the term of this agreement automatically renewed through March 31, 2007. The agreement requires us to use our commercially reasonable efforts while Mr. Greubel is serving as our Chief Executive Officer to cause him to be nominated for election to the Board of Directors. Pursuant to this agreement, Mr. Greubel's initial base salary was set at $600,000 per year, subject to annual adjustment in connection with annual performance reviews and discussions between Mr. Greubel and us. Mr. Greubel's current base salary is $710,000. Mr. Greubel is also eligible for an annual bonus targeted at 100% of his base salary and which may range from 0% to 100% of that year's base salary. Pursuant to the terms of the agreement, the Board of Directors granted Mr. Greubel an initial option grant to purchase 250,000 shares of our Common Stock at an exercise price of $10.01 per share. One-third of these options vested on each of the first, second and third anniversary of Mr. Greubel's employment. In the event that we terminate Mr. Greubel's employment without cause, or it is terminated by Mr. Greubel as a result of a material diminishment of his position, duties or responsibilities; our assignment to Mr. Greubel of substantial additional duties or responsibilities which are inconsistent with the duties or responsibilities then being carried out by him and which are not duties of an executive nature; our material breach of the agreement, which is not corrected within twenty (20) business days of the receipt of a written notice specifying the breach; material fraud on our part; or the discontinuance of the active operation of our business or our insolvency or bankruptcy, we will pay to Mr. Greubel the sum of two times his then current base salary. In addition, all unvested options then held by Mr. Greubel shall become vested. If we terminate Mr. Greubel's employment without cause, upon the attainment of corporate objectives, he is entitled to receive a pro-rata portion of his bonus for the year in which he is terminated. Mr. Greubel has agreed not to compete with us during the term of his agreement and for a period of two years after termination for any reason. Mr. Greubel is also entitled to a severance package in the event that his employment is terminated following a change of control of Wabash, as more specifically described in the "Compensation Committee Report on Executive Compensation" above. In June 2002, we also entered into an employment agreement with Mr. Giromini, pursuant to which Mr. Giromini now serves as our President and Chief Operating Officer, commencing July 15, 2002 through July 15, 2003. The term of Mr. Giromini's employment automatically renews for successive one-year periods unless and until either party provides written notice, not less than 60 days prior to the end of the then current term, of his or its intent not to renew the agreement. Neither party provided the other with notice of the intent not to renew this agreement prior to July 15, 2005; therefore the term of this agreement automatically renewed through July 15, 2006. Pursuant to this agreement, Mr. Giromini's initial base salary was set at $325,000 per year, subject to annual adjustment in connection with annual performance reviews and discussions between Mr. Giromini and us. Mr. Giromini's current base salary is $451,000. Mr. Giromini is also eligible for an annual bonus targeted at 60% of his base salary and which may range from 0% to 60% of that year's base salary. Pursuant to the terms of the agreement, the Board of Directors granted Mr. Giromini an initial option grant to purchase 125,000 shares of our Common Stock at an exercise price of $8.65 per share. Two-thirds of these options vested on the second anniversary of Mr. Giromini's employment and the remaining one-third of these options vested on the third anniversary of Mr. Giromini's employment. In the event that we terminate Mr. Giromini's employment without cause, or it is terminated by Mr. Giromini as a result of a material diminishment of his position, duties or responsibilities; our assignment to Mr. Giromini of substantial additional duties or responsibilities which are inconsistent with the duties or responsibilities then being carried out by him and which are not duties of an executive nature; our material breach of 23 the agreement, which is not corrected within twenty (20) business days of the receipt of a written notice specifying the breach; material fraud on our part; or the discontinuance of the active operation of our business or our insolvency or bankruptcy, we will pay to Mr. Giromini the sum of two times his then current base salary. In addition, all unvested options then held by Mr. Giromini shall become vested. If we terminate Mr. Giromini's employment without cause, upon the attainment of corporate objectives, he is entitled to receive a pro-rata portion of his bonus for the year in which he is terminated. Mr. Giromini has agreed not to compete with us during the term of his agreement and for a period of two years after termination for any reason. Mr. Giromini is also entitled to a severance package in the event that his employment is terminated following a change of control of Wabash, as more specifically described in the "Compensation Committee Report on Executive Compensation," above. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The Compensation Committee of the Board of Directors in 2005 consisted of Messrs. Hackett, Koci, Burdakin, Jischke, Magee, Sorensen, Stewart and Ms. Kushner. None of these individuals is currently, or has ever been, an officer or employee of Wabash or any of our subsidiaries. In addition, during 2005, none of our executive officers served as a member of the board of directors or on the compensation committee of any other entity that had an executive officer serving on our Board of Directors or our Compensation Committee.

There are no securities that are currently issuable under the Wabash National Corporation Directors and Executives Deferred Compensation Plan, and the number of securities available for grant under that plan is indeterminable as that number is dependent upon future deferrals by eligible participants. (2) Consists of shares of Common Stock to be issued upon exercise of outstanding options granted under the Wabash National Corporation 2000 Stock Option and Incentive Plan, shares of Common Stock to be issued under the Wabash National Corporation Stock Bonus Plan, shares of Common Stock to be issued under the Wabash National Corporation Employee Stock Purchase Plan and inducement options that were granted outside of any formal corporate plan. (3) Consists of shares of Common Stock available for future issuance pursuant to our 2004 Stock Incentive Plan. All 570,464 shares of Common Stock available as of December 31, 2005 for future issuance under this plan were available for future issuance pursuant to grants in the form of restricted stock, stock units, unrestricted stock and other incentive awards, subject to certain limitations in the plan. RESTRICTED STOCK AND STOCK UNIT GRANTS We have issued an aggregate of 232,370 shares of restricted stock and stock units pursuant to the Wabash National Corporation 2004 Stock Incentive Plan, of which 21,600 were forfeited or otherwise cancelled, and 7,750 vested, on or before December 31, 2005, with 203,020 remaining subject to forfeiture as of that date. We have issued an aggregate of 25,605 shares of restricted stock pursuant to the Wabash National Corporation 2000 Stock Option and Incentive Plan, of which 12,730 were forfeited or otherwise cancelled, and 8,375 vested, on or before December 31, 2005, with 4,500 remaining subject to forfeiture as of that date. We have issued an aggregate of 58,054 shares of restricted stock in the form of inducement grants, none of which were subject to forfeiture as of December 31, 2005. 2000 STOCK OPTION AND INCENTIVE PLAN Our Board of Directors adopted the Wabash National Corporation 2000 Stock Option and Incentive Plan effective November 2000. This plan provides for the grant of non-qualified stock options and restricted stock in order to attract, retain and compensate Directors, highly qualified officers, key employees and other persons. There were 2,000,000 shares of stock originally authorized for issuance under the plan. The exercise price for each option 27 granted is set by the Compensation Committee, but is required to be at least the fair market value of a share of our Common Stock on the date of grant. The Compensation Committee sets the vesting schedule for each option granted and sets the restricted period for each grant of restricted stock. Upon a change in control of Wabash, all outstanding shares subject to options vest and all restrictions and conditions applicable to shares subject to restricted stock lapse. The term of the plan is 10 years, unless earlier terminated by the Board of Directors. As a result of the approval of the 2004 Stock Incentive Plan at our 2004 annual meeting of stockholders, the number of shares available for grant under the 2000 Stock Option and Incentive Plan was reduced to 100,000 shares, which remain available. EMPLOYEE STOCK PURCHASE PLAN Our Board of Directors adopted the Wabash National Corporation Employee Stock Purchase Plan effective June 1993. This plan provides for the purchase of our Common Stock by certain employees in order to increase the employees' interest in our growth and success and to retain the employees' services. An employee purchases the stock by electing to have deducted from his or her payroll a whole percentage amount of at least two percent and no more than 15 percent of the employee's daily compensation. There were 200,000 shares of Common Stock originally authorized for issuance under the Employee Stock Purchase Plan. The purchase price for each share of Common Stock is the fair market value of the Common Stock on the last day of the applicable period. The Board of Directors may terminate this plan at any time. As of December 31, 2005, 241,736 shares of Common Stock remained available for grant under this plan. STOCK BONUS PLAN Our Board of Directors adopted the Wabash National Corporation Stock Bonus Plan effective January 1, 1997. This plan provides that stock may be awarded as supplementary compensation as an incentive and reward to eligible long service employees who, through industry, ability and exceptional service, contribute materially to our success. There were 500,000 shares of stock originally authorized for issuance under the Stock Bonus Plan. The Board of Directors has the authority to determine, in its sole discretion, the amount of individual stock bonus awards. This plan may be amended, suspended or terminated by the Board of Directors at any time. As of December 31, 2005, 453,490 shares of Common Stock remained available for grant under this plan, which amount reflects our 3 for 2 stock split in July 1994. INDUCEMENT GRANTS We have issued non-qualified stock options outside of any plan in connection with inducing certain individuals to accept employment by us. In the aggregate, we have issued options to purchase 385,000 shares of Common Stock to three individuals. The exercise price for each option granted was set by the Compensation Committee at the fair market value of the shares subject to that option. The Compensation Committee set vesting schedules that vest over three years. Upon a change in control of Wabash, all outstanding shares subject to options vest. The term of each option is 10 years.

Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting and will have an opportunity to make a statement if they desire and are expected to be available to respond to appropriate questions. PRINCIPAL ACCOUNTING FEES AND SERVICES The fees billed by Ernst & Young LLP for professional services provided to us for the years ended December 31, 2005 and December 31, 2004 were as follows: FEE CATEGORY 2005 2004 ------------ ---------------------- ------ (DOLLARS IN THOUSANDS) Audit Fees $1,250 $1,390 Audit-Related Fees 15 97 Tax Fees 107 136 All Other Fees 177 0 ------ ------ Total Fees $1,549 $1,623 Audit Fees. Consist of fees billed for professional services rendered for the audit of our consolidated financial statements, review of the interim consolidated financial statements included in quarterly reports and services provided by Ernst & Young LLP in connection with our securities offerings and registration statements. Audit-Related Fees. Consist of fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under "Audit Fees." In 2004 and 2005, these services included audits of benefit plans, audits, accounting consultation, consulting on internal controls and other audit-related services. Tax Fees. Consist of fees billed for professional services for tax compliance, tax advice and tax planning. In 2004 and 2005, these services include assistance related to state tax filing and incentives reviews of corporation tax filings, consulting or net operating loss treatments, and review of tax audits. All Other Fees. In 2005, these services include the performance of financial due diligence and other related services provided in connection with our acquisition of the outstanding stock of Transcraft Corporation, which transaction closed in March 2006. In 2005, all Ernst & Young LLP fees were pre-approved by the Audit Committee pursuant to the policy described below or related to contracts existing on May 11, 2005. After consideration, the Audit Committee has concluded that the provision of non-audit services by Ernst & Young LLP to Wabash is compatible with maintaining the independence of Ernst & Young LLP. The Audit Committee has not yet selected our auditors for the year ending December 31, 2006. As part of our ongoing process of evaluating services and costs, the Audit Committee is evaluating its options. 29 PRE-APPROVAL POLICY FOR AUDIT AND NON-AUDIT FEES The Audit Committee's policy is to pre-approve all audit and permissible non-audit services performed by our independent public accountants. These services may include audit services, audit-related services, tax services and other services. For audit services, the independent auditor provides an engagement letter in advance of the meeting of the Audit Committee that occurs in connection with our annual meeting of stockholders, outlining the scope of the audit and related audit fees. If agreed to by the Audit Committee, this engagement letter is formally accepted by the Audit Committee at the meeting of the Audit Committee. For all services, our senior management submits to the Audit Committee a request that the Audit Committee approve specific services recommended by management and engage our independent auditor to provide such services. In addition, the Audit Committee pre-approves all non-audit services that the independent auditor is permitted to provide from time-to-time during the year. Prior to approval by the Audit Committee, all fee proposals for non-audit services must be approved in advance in writing by the requesting department head and by the Corporate Controller. Any fee proposal greater than $25,000 must also be approved in advance in writing by the Chief Financial Officer. Any fee proposal greater than $100,000 must also be approved in advance in writing by the Chairman of the Audit Committee. The Audit Committee will be informed routinely as to the non-audit services actually provided by the independent auditor pursuant to this pre-approval process.
