PROXY STATEMENT
FOR 2008 ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON JUNE 9, 2008

        This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of Willdan Group, Inc., a Delaware corporation (the "Company"), for use at its 2008 Annual Meeting of Stockholders to be held on Monday, June 9, 2008 at 10:00 a.m. Pacific Daylight Time at The Hyatt Regency Orange County, 11999 Harbor Blvd., Garden Grove, California 92840, and at any adjournment or postponement thereof (the "Annual Meeting"). This Proxy Statement and the accompanying Notice of Annual Meeting of Stockholders and Proxy are first being sent to stockholders on or about May 9, 2008. The Company's 2007 Annual Report, including financial statements for the fiscal year ended December 28, 2007, is being mailed to stockholders concurrently with this Proxy Statement. The Annual Report, however, is not part of the proxy solicitation material.


ABOUT THE ANNUAL MEETING

What is the purpose of the Annual Meeting?

        At the Annual Meeting, our stockholders will consider and vote on the following matters:

        In addition, our stockholders will transact any other business that properly comes before the meeting. Management of the Company will also respond to any questions from our stockholders.

Who can attend the Annual Meeting?

        All stockholders of the Company as of the Record Date, or their duly appointed proxy holders, may attend the Annual Meeting.

Who is entitled to vote?

        Only holders of record of the Company's common stock, $0.01 par value per share (the "Common Stock"), at the close of business on the record date, April 11, 2008 (the "Record Date"), are entitled to notice of and to vote at the Annual Meeting. Holders of Common Stock are entitled to cast one vote for each share held by them on each matter to be voted upon. The Common Stock is the only class of securities of the Company authorized to vote. Under the Company's Certificate of Incorporation and applicable law, a stockholder is not entitled to cumulative voting rights in the election of directors.

What constitutes a quorum?

        The presence, in person or by proxy, of holders entitled to cast at least a majority of all the votes entitled to be cast is necessary to constitute a quorum for the transaction of business at the Annual Meeting. As of the Record Date, 7,156,461 shares of Common Stock were outstanding and entitled to vote. Abstentions and broker "non-votes" will count toward the presence of a quorum. A broker non-vote occurs when a broker, bank or other nominee holding shares for a beneficial owner returns an


executed proxy, but strikes out a particular proposal because the nominee does not have discretionary voting power with respect to that matter and has not received voting instructions from the beneficial owner.

How do I vote?

        If you are a registered stockholder, you may vote in person at the Annual Meeting or by proxy without attending the meeting. To vote by proxy, please mark, date, sign, and return the proxy card you received with this proxy statement in the enclosed envelope. If you sign and return the proxy card but do not give any instructions, your shares will be voted by the persons named in the proxy card in accordance with the recommendations of the Board of Directors given below.

        If your stock is held in the name of a broker, bank or other nominee, please mark, date, sign, and return the voting instruction form you received from your broker or nominee with this proxy statement.

        If you are a registered stockholder and wish to vote in person at the meeting, be sure to bring a form of personal picture identification with you. If your stock is held by a broker, bank or other nominee (in "street name") and you wish to vote in person at the meeting, in addition to picture identification you should bring an account statement or a letter from the record holder indicating that you owned the shares as of the record date, and obtain from the record holder and bring with you a proxy from the record holder issued in your name.

Can I change my vote after I return my proxy card?

        Yes. Even after you have submitted your proxy, you may change your vote at any time before the proxy is exercised by delivering a duly executed proxy bearing a later date or a written revocation to the Secretary or Assistant Secretary of the Company at the address of the Company set forth above or by attending the Annual Meeting and voting in person. Any stockholder of record as of the Record Date attending the Annual Meeting may vote in person, whether or not a proxy has been previously given, but the presence (without further action) of a stockholder at the Annual Meeting will not constitute revocation of a previously given proxy.

What are the Board of Directors' recommendations?

        Unless you give other instructions on your proxy, the persons named as proxy holders on the proxy will vote in accordance with the recommendations of the Company's Board of Directors. The Board's recommendations are set forth together with the description of each matter in this Proxy Statement. In summary, the Board unanimously recommends a vote: FOR election of each of the seven nominees for director; FOR ratification of the appointment of KPMG LLP as the Company's independent registered public accounting firm for the year ending January 2, 2009; and FOR approval of the 2008 Plan.

        With respect to any other matter that properly comes before the meeting, the proxy holders will vote as recommended by the Board of Directors or, if no recommendation is given, in the discretion of the proxy holders.

What vote is required to approve each matter?

        Assuming the presence of a quorum, the affirmative vote of a plurality of all of the votes cast on the matter at the Annual Meeting in person or by proxy will be required for the election of each director nominee and the affirmative vote of a majority of all of the votes cast on the matter at the Annual Meeting in person or by proxy will be required for the ratification of the appointment of KPMG LLP to serve as the Company's independent registered public accounting firm and the approval of the 2008 Plan. Abstentions are not counted as votes cast and will have no effect on the vote for the

2


election of the directors, the ratification of the appointment of KPMG LLP or the approval of the 2008 Plan.

Who tabulates the votes?

        Stockholder votes will be tabulated by the persons appointed to act as inspectors of election for the Annual Meeting.

Could other matters be decided at the meeting?

        It is not anticipated that any matter, other than those set forth in this Proxy Statement, will be presented at the Annual Meeting. If other matters are presented, proxies will be voted by the proxy holders in accordance with the recommendation of the Board of Directors or, if no recommendation is given, in the discretion of the proxy holders.

What happens if the Annual Meeting is postponed or adjourned?

        Your proxy may be voted at the postponed or adjourned Annual Meeting. You will still be able to change your proxy until it is voted.

How can I receive a copy of the Annual Report?

        The Annual Report, which includes the Company's Annual Report on Form 10-K for the year ended December 28, 2007, accompanies this proxy statement and may also be accessed through our web site at www.willdan.com under "Investors—SEC Filings".

Where can I find the voting results of the Annual Meeting?

        Our intention is to announce the preliminary voting results at the Annual Meeting and to publish the final results in our quarterly report on Form 10-Q for the second quarter of fiscal 2008, which we will file with the United States Securities and Exchange Commission (the "SEC") and make available on our web site at www.willdan.com under "Investors—SEC Filings".

PROPOSAL 1:

ELECTION OF DIRECTORS

        The Bylaws provide that the Board of Directors consists of five directors until changed by the Board of Directors. On April 2, 2007, the Board of Directors increased the size of the Board to seven directors. The directors are regularly elected at each annual meeting of the stockholders, and each director shall hold office until his/her successor has been elected and qualified or until his/her earlier resignation or removal.

        The seven directors, if elected at the Annual Meeting, will hold office until the next annual meeting of stockholders, or until an earlier stockholder meeting at which directors are elected, and until their respective successors are duly elected and qualified. The Board of Directors, based on the recommendations of the Nominating and Corporate Governance Committee, has nominated Win Westfall, Thomas D. Brisbin, Linda L. Heil, W. Tracy Lenocker, Keith W. Renken, John M. Toups and Wayne Shelton to continue to serve as directors of the Company (collectively, the "Nominees").

        Each of the Nominees is currently serving as a director of the Company and has consented to be nominated and to serve if elected. However, if any Nominee is unavailable for election or unable to serve, the proxy holders may vote for another person nominated by the Board of Directors or the Board may amend the Bylaws to reduce the number of directors to be elected at the Annual Meeting.

Information Regarding Nominees and Directors

        The following table sets forth certain information with respect to the Nominees, each of whom is currently serving and, unless otherwise specified, has served continuously since he or she was previously elected, based on information furnished to the Company by each such director. The following information is as of April 23, 2008, unless otherwise specified.

The Board of Directors

        The Company is managed under the direction of a Board of Directors composed of seven members, of which the Board has determined that four of the members are independent under the rules of the Nasdaq Global Market.

        Board members are expected to attend each Board meeting and each meeting of any committee on which each Board member serves and are encouraged to attend the Annual Meeting of Stockholders. The Board of Directors met 10 times in 2007. Each incumbent director attended at least 75% of the total number of meetings of the Board of Directors and of each committee on which he or she served during 2007. Each incumbent director attended the 2007 Annual Meeting. Stockholders or other interested parties may communicate with members of the Board of Directors individually or with the Board of Directors as a whole by sending a letter to the appropriate director or the Board of Directors in care of the Assistant Secretary of the Company at the address shown below under "—Communications with the Board of Directors."

        Non-management directors meet regularly in executive sessions without management. "Non-management" directors are all those who are not Company officers or employees and include directors, if any, who are not independent by virtue of the existence of a material relationship with the Company, former status or family relationship or for any other reason. Executive sessions are led by a "Lead Director." An executive session is held in conjunction with each regularly scheduled quarterly Board meeting and other sessions may be called by the Lead Director in his own discretion or at the request of the Board. Keith W. Renken has been designated as the Lead Director.

6

        The Company has established standards of independence for the Board of Directors that comply with the listing standards for the Nasdaq Global Market (the "Nasdaq Rules") and the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Under these standards of independence, for a director to be considered independent, the director must, among other things, not be an officer or employee of the Company or its subsidiaries and the director must not have a relationship which, in the opinion of the Board of Directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

        The Board of Directors has determined that Messrs. Renken, Lenocker, Toups and Shelton are "independent" directors under the standards set forth in the Nasdaq Rules. The Board of Directors has deemed Mr. Lenocker to be an independent director under the Nasdaq Rules notwithstanding the fact that he served briefly as the Company's interim President and Chief Executive Officer from February 2007 to April 2007. The Board of Directors determined that Mr. Lenocker's former status as interim President and Chief Executive Officer is not material to the determination of independence and also relied on Nasdaq Interpretive Material in determining that Mr. Lenocker could be deemed an independent director after serving in this interim capacity. However. Mr. Lenocker does not currently meet the standards set forth under the Exchange Act for membership on the Audit Committee.

        We have four standing committees: the Audit Committee, the Compensation Committee, the Nominating and Corporate Governance Committee and the Investment, Finance and Strategy Committee. The charters for each of these committees are available on our website at www.willdan.com under "Investors—Corporate Governance—Governance Documents" or are available in print to any stockholder who requests a copy from the Company's Assistant Secretary at 2401 East Katella Avenue, Suite 300, Anaheim, California 92806. Each of these committees is composed only of independent directors and regularly reports to the Board of Directors as a whole.

        Audit Committee.    The Board's Audit Committee consists of Messrs. Renken, Toups and Shelton, each of whom the Board has determined is an independent director and meets the independence requirements for Audit Committee members under the Nasdaq Rules and the Exchange Act. Mr. Renken is the chairman of the Committee and has been designated by the Board as the Audit Committee financial expert. Each of the other members of the Audit Committee is financially literate. The Audit Committee met seven times during 2007.

        Under the terms of the Audit Committee Charter, the purpose of this Committee is to assist the Board in overseeing the integrity of the Company's financial statements and financial reporting, the Company's compliance with legal and regulatory requirements, the qualifications and independence of the Company's independent registered public accounting firm, the performance of the Company's internal reporting and audit functions, and the Company's disclosure controls and procedures and system of internal controls regarding finance, accounting, legal compliance and ethics. The Audit Committee confers formally with the Company's independent registered public accounting firm, as well as with members of management to inquire as to the manner in which the respective responsibilities of these groups and individuals are being discharged. The Audit Committee engages our independent registered public accounting firm and reviews and approves the scope of the audit conducted by the independent registered public accounting firm.

        Compensation Committee.    The Board's Compensation Committee consists of Messrs. Lenocker and Renken, each of whom the Board has determined is an independent director under the Nasdaq Rules, with Mr. Lenocker serving as the Committee's chairman. The Compensation Committee is responsible for establishing and governing the compensation and benefit practices of the Company. The Compensation Committee Charter requires that the Compensation Committee consist of two or more

7


members of the Board, each of whom satisfies the independence requirements under Nasdaq Rules and the Exchange Act. At all times during fiscal 2007 the Compensation Committee consisted of at least two members of the Board, each of whom the Board has affirmatively determined satisfies these independence requirements. The Compensation Committee met seven times during fiscal 2007.

        The Compensation Committee assists the Board of Directors in determining the compensation of the Company's executive officers and senior management, recommends to the Board annual and long-term compensation for the Company's executive officers and senior management and prepares an annual report on its activities and determinations for inclusion in the Company's proxy statement in accordance with applicable rules and regulations. In addition to its annual review of the compensation of the Company's officers, the Compensation Committee administers the Company's 2008 Plan, 2006 Stock Incentive Plan and Employee Stock Purchase Plan. The Committee has the authority to designate officers, directors or key employees eligible to participate in the plans, to prescribe the terms of any award of stock options, to interpret the plans, and to make all other determinations for administering the plans. Our Chief Executive Officer recommends to the Compensation Committee salary, annual bonus and long-term compensation levels for less senior officers, including the other Named Officers (as defined below). Our other executive officers, including the other Named Officers, do not currently have any role in determining or recommending the form or amount of compensation paid to our Named Officers and our other senior executive officers.

        The Compensation Committee is authorized to retain and terminate any compensation consultant engaged to assist in the evaluation of the compensation of our senior executive officers (including all of the Named Officers). The Compensation Committee has not retained the services of a compensation consulting firm.

        Nominating and Corporate Governance Committee.    The Nominating and Corporate Governance Committee consists of Messrs. Lenocker and Renken, each of whom the Board has determined is an independent director under the Nasdaq Rules, with Mr. Lenocker serving as the Committee's chairman. The Nominating and Corporate Governance Committee met six times in 2007.

        The Nominating and Corporate Governance Committee works with the Board of Directors to determine the appropriate characteristics, skills, and experience for the Board as a whole and its individual members. In evaluating the suitability of individual Board members, the Nominating and Corporate Governance Committee and the Board take into account many factors, including general understanding of marketing, finance, and other disciplines relevant to the success of a publicly traded company; understanding of our business; education and professional background, including current employment and other board memberships; and reputation for integrity. These factors, and others considered useful by the Nominating and Corporate Governance Committee, will be reviewed in the context of an assessment of the perceived needs of the Board at a particular point in time. After assessing the perceived needs of the Board, the Nominating and Corporate Governance Committee identifies specific individuals and looks to well respected companies as a potential source of director candidates with relevant experience. The priorities and emphasis of the Nominating and Corporate Governance Committee and of the Board may change from time to time to take into account changes in business and other trends and the portfolio of skills and experience of current and prospective Board members. The Nominating and Corporate Governance Committee establishes procedures for the nomination process and recommends candidates for election to the Board.

        Investment, Finance and Strategy Committee.    The Board's Investment, Finance and Strategy, or IFS, Committee consists of Messrs. Toups, Shelton and Renken, with Mr. Toups serving as the Committee's chairperson. The IFS Committee assists the Board by reviewing and making recommendations to the Board or taking actions on behalf of the Board relating to the Company's financial and strategic plans. The IFS Committee Charter requires that the IFS Committee consist of three or more members of the Board, each of whom the Board has determined satisfies the

8


independence requirements under the Nasdaq Rules and the Exchange Act. The IFS Committee was formed in February 2008 and therefore did not meet during fiscal 2007.

        The responsibilities of the IFS Committee include reviewing with management, on a timely basis, significant financial matters of the Company and its subsidiaries, including matters relating to the Company's capitalization, dividend policy and practices, banking relationships, credit ratings, cash flows, borrowing activities, investment strategies, and potential acquisitions. The Committee also reviews and may recommend to the Board actions relating to: offerings of the Company's debt or equity securities; purchases or disposals of treasury shares, except the purchase of shares pursuant to approved employee benefit plans; stock splits or reclassification of shares; the declaration and payment of any dividends on the Company's common stock; guarantees of unconsolidated third party indebtedness; and certain other financial transactions and strategies.

        Consideration of new Board nominee candidates involves a series of internal discussions, review of information concerning candidates, and interviews with selected candidates. Board members or employees typically suggest candidates for nomination to the Board.

        The Board of Directors will consider director candidates recommended by stockholders for inclusion on the slate of directors nominated by the Board of Directors. Any stockholder may submit one candidate for consideration in conformity with the Bylaws and as set forth hereafter under the caption "Other Information—Stockholder Proposals." Stockholders wishing to recommend a candidate must submit the recommendation to the Nominating and Corporate Governance Committee, c/o the Assistant Secretary, Willdan Group, Inc., 2401 East Katella Avenue, Suite 300, Anaheim, California 92806. If a nominating stockholder is not a record holder, the stockholder must provide the same evidence of eligibility as set forth in Exchange Act Rule 14a-8(b)(2).

        At the time the nominating stockholder submits the recommendation, the candidate must submit all information about the candidate that the Company would be required to disclose in a proxy statement in accordance with Exchange Act rules. In addition, at that time the candidate must:


        The Nominating and Corporate Governance Committee will evaluate any stockholder-recommended candidate to determine whether he or she is highly-qualified. Particular consideration will be given to those individuals who have substantial achievement in their personal and professional pursuits and whose talents, experience and integrity would be expected to contribute to the best interests of the Company and to long-term stockholder value. Without limitation, the Committee recommends individuals who have a general management focus, have specialization in the Company's principal business activities or finance, have significant experience in issues encountered by public companies and who could contribute to the diversity of the board. The Nominating and Corporate Governance Committee evaluates stockholder-recommended candidates in the same way it evaluates candidates proposed from other sources.

        The Company expects that all of its directors, officers and employees will maintain a high level of integrity in their dealings with and on behalf of the Company and will act in the best interests of the Company. The Company has adopted a Code of Ethical Conduct which provides principles of conduct and ethics for the Company's directors, officers and employees. This Code complies with the requirements of the Sarbanes-Oxley Act of 2002 and the Nasdaq Rules. This Code of Ethical Conduct is available on the Company's website at www.willdan.com under "Investors—Corporate Governance—Governance Documents" and is also available in print to any stockholder who requests a copy by writing to our corporate secretary at 2401 East Katella Avenue, Suite 300, Anaheim, California 92806.

        There are currently no ongoing material proceedings in which any director or executive officer is a party adverse to the Company or any of its subsidiaries, or in which any director or executive officer has a material interest adverse to the Company or any of its subsidiaries.

        Individuals may contact the Company's entire Board of Directors or an individual director by sending a written communication to the Board or such director in care of:

        Each communication must set forth the name and address of the stockholder on whose behalf the communication is sent. Each communication will be reviewed by the Company's Secretary or Assistant Secretary to determine whether it is appropriate for presentation to the Board or such director. Advertisements, solicitations or hostile communications will not be presented. Communications determined by the Secretary to be appropriate for presentation to the Board or such director will be submitted to the Board or such director on a periodic basis.

        A stockholder wishing to communicate directly with the non-management members of the board may address the communication to "Non-Management Directors, c/o Board of Directors" at the same address set forth above. These communications will be handled by the chairman of the Audit Committee, who is currently designated to preside at the meetings of non-management directors. Finally, communications can be sent directly to individual directors by addressing letters to the director's individual name, c/o the Board of Directors, at the address above.

        The following table presents information regarding the compensation earned during fiscal 2007 by individuals who were members of our Board of Directors at any time during fiscal 2007 and who were not also our employees (referred to herein as "Non-Employee Directors"). The compensation earned by any director who was also one of our Named Officers (as defined below) is presented below in the Summary Compensation Table and the related explanatory tables. Such employee-directors are

As of December 28, 2007, none of our Non-Employee Directors held any outstanding stock awards.

The amounts reported under "Option Awards" above reflect the aggregate dollar amounts recognized for option awards for financial statement reporting purposes with respect to fiscal 2007 (disregarding any estimate of forfeitures related to service-based vesting conditions). For a discussion of the assumptions and methodologies used to calculate the amounts reported in this column, please see the discussion of option awards contained in Note 5 (Stock Options) to our consolidated financial statements, included as part of our annual report filed on Form 10-K.

The amounts reported under "All Other Compensation" with respect to Mrs. Heil includes (i) $14,080 for the estimated value of medical benefit coverage for fiscal 2007 granted to Mrs. Heil and her two dependents in May 2006 and (ii) $10,000 earned by Mrs. Heil as compensation for conducting interviews of Chief Executive Officer candidates in fiscal 2007. With respect to Mr. Renken and Ms. Smith, the amounts reported under "All Other Compensation" relate to compensation earned for conducting interviews of Chief Executive Officer candidates in fiscal 2007.

(4)
Ms. Smith resigned from our Board of Directors on April 20, 2008.

        Compensation for Non-Employee Directors during fiscal 2007 generally consisted of an annual retainer, fees for attending meetings, fees for work related to board committees and a stock option award. For the purposes of the below discussion, "Non-Employee Directors" also includes Mr. Lenocker because he did not serve on the Board of Directors at the same time that he was an employee of the Company.

        The following table sets forth the schedule of meeting fees and annual retainers for each Non-Employee Director in effect during fiscal 2007:

Type of Fee
   Dollar Amount
Annual Board Retainer   $ 30,000
Additional Annual Retainer to Chair of Audit Committee   $ 5,000
Additional Annual Retainer to Chair of Compensation Committee   $ 2,500
Additional Daily Fee for Personal Attendance at Board, Stockholder or Committee Meetings   $ 2,500
Additional Daily Fee for Telephonic Attendance at Board, Stockholder or Committee Meetings   $ 1,500

        All Non-Employee Directors are also reimbursed for out-of-pocket expenses they incur serving as directors.

        In June 2007, each Non-Employee Director was granted an award of 2,000 stock options under the Company's 2006 Stock Incentive Plan. The stock option awards were granted with a per-share exercise price equal to the fair market value of a share of the Company's Common Stock on the grant date. For these purposes, and in accordance with the terms of the 2006 Stock Incentive Plan and the Company's equity award grant practices, the fair market value is equal to the closing price of a share of the Company's Common Stock on the Nasdaq Global Market on the grant date.

        Each stock option granted to our Non-Employee Directors in fiscal 2007 will be fully vested as of June 12, 2009. Stock options granted to our Non-Employee Directors in fiscal 2007 are subject to a two (2) year vesting schedule, with 50% of the option vesting on each of the first and second anniversaries of the grant date. Once vested, each stock option will generally remain exercisable until its normal expiration date. The stock options granted to our Non-Employee Directors in fiscal 2007 have a term of ten (10) years. Outstanding stock options, however, may terminate earlier in connection with a change in control transaction or a termination of the Non-Employee Director's services as a director. Subject to any accelerated vesting that may apply in the circumstances, the unvested portion of the stock option will immediately terminate upon a termination of the Non-Employee Director's services as a director. The Non-Employee Director will generally have three (3) months to exercise the vested portion of the stock option following a termination of service. This period is extended to twelve (12) months if the termination is on account of the Non-Employee Director's death or permanent disability. The options granted to Non-Employee Directors in fiscal 2007 do not include any dividend or dividend equivalent rights.

        The Board of Directors administers the 2006 Stock Incentive Plan as to Non-Employee Director awards and has the ability to interpret and make all required determinations under the plan, subject to plan limits. This authority includes making required proportionate adjustments to outstanding awards to reflect any impact resulting from various corporate events such as reorganizations, mergers and stock splits. Pursuant to the terms of the 2006 Stock Incentive Plan, stock options granted to our Non-Employee Directors will generally vest on an accelerated basis in connection with a change in control of the Company to the extent such awards are not substituted or assumed by a successor in connection with the transaction.

Vote Required for Election of Each Director

        Election of each director requires the affirmative vote of a plurality of all of the votes cast on the matter at the Annual Meeting.

        THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE ELECTION OF EACH OF THE NOMINEES. PROXIES RECEIVED WILL BE VOTED "FOR" EACH OF THE NOMINEES UNLESS STOCKHOLDERS SPECIFY OTHERWISE IN THE PROXY.

PROPOSAL 2:

RATIFICATION OF THE APPOINTMENT OF KPMG LLP
AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        The Audit Committee has appointed KPMG LLP as the Company's independent registered public accounting firm to audit its financial statements for the year ending January 2, 2009.

        Although ratification by stockholders is not required by law, the Board has determined that it is desirable to request approval of this appointment by the stockholders. If the stockholders do not ratify the appointment, the Audit Committee will reconsider whether or not to retain KPMG LLP, and may decide to retain them notwithstanding the vote. Even if the appointment is ratified, the Audit Committee in its discretion may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders. In addition, if KPMG LLP should decline to act or otherwise become incapable of acting, or if the employment should be discontinued, the Audit Committee will appoint a substitute independent public registered public accounting firm. A representative of KPMG LLP will be present at the Annual Meeting, will be given the opportunity to make a statement if he or she so desires and will be available to respond to appropriate questions.

Principal Accountant's Fees and Services

        The following is a summary of the fees billed to us by KPMG LLP for professional services for the fiscal years ended December 28, 2007 and December 29, 2006, respectively:

Fee Category
   Fiscal 2007 Fees
   Fiscal 2006 Fees
Audit Fees   $ 361,000   $ 1,284,023
Audit-Related Fees     —     —
Tax Fees     —     —
All Other Fees     —     —
   
 
Total Fees   $ 361,000   $ 1,284,023
   
 

        Fees for audit services provided by KPMG for fiscal 2007 and fiscal 2006 consisted of professional services for the annual audit of our consolidated financial statements and for review of our interim condensed consolidated financial statements including quarterly reports. Fees for audit services for fiscal 2006 included fees for audit services performed in connection with the Company's initial public offering. The initial public offering related services included audits of the Company's consolidated financial statements for fiscal 2005 and fiscal 2004 performed during fiscal 2006.

        No fees for audit-related services were billed by KPMG LLP in 2007 or 2006.

        No fees for tax services, including tax return preparation, tax compliance, tax advice and tax planning, were billed by KPMG LLP in 2007 or 2006.

        There were no fees paid for any other services not described above in 2007 or 2006.

13

        The Company has been advised by KPMG LLP that neither the firm, nor any member of the firm, has any financial interest, direct or indirect, in any capacity in the Company or its subsidiaries.

Audit Committee Pre-Approval Policy

        Consistent with SEC policies regarding independence, the Audit Committee has responsibility for appointing, setting compensation and overseeing the work of the independent registered public accounting firm. In recognition of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent registered public accounting firm, including audit services, audit-related services, tax services, and other services. In some cases, the full Audit Committee provides pre-approval for up to a year, related to a particular defined task or scope of work and subject to a specific budget. During the year, circumstances may arise when it becomes necessary to engage the independent registered public accounting firm for additional services not contemplated in the original pre-approval categories. In those instances, the Audit Committee requires specific pre-approval before engaging the independent registered public accounting firm. The Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next regularly scheduled meeting.

Vote Required for Ratification of the Appointment of KPMG LLP as the Company's Independent Registered Public Accounting Firm

        Ratification of the appointment of KPMG LLP as the Company's independent registered public accounting firm requires the affirmative vote of a majority of all the votes cast on the matter at the Annual Meeting.

        THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE PROPOSAL TO RATIFY THE APPOINTMENT OF KPMG LLP AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING JANUARY 2, 2009. PROXIES RECEIVED WILL BE VOTED "FOR" RATIFICATION UNLESS STOCKHOLDERS SPECIFY OTHERWISE IN THE PROXY.

PROPOSAL 3:

APPROVAL OF THE WILLDAN GROUP, INC.
2008 PERFORMANCE INCENTIVE PLAN

General

        At the Annual Meeting, stockholders will be asked to approve the Willdan Group, Inc. 2008 Performance Incentive Plan (the "2008 Plan"), which was adopted, subject to stockholder approval, by the Board of Directors on March 10, 2008.

        The Company believes that incentives and stock-based awards focus employees on the objective of creating stockholder value and promoting the success of the Company, and that incentive compensation plans like the proposed 2008 Plan are an important attraction, retention and motivation tool for participants in the plan.

        The Company currently maintains the Willdan Group, Inc. 2006 Stock Incentive Plan (the "2006 Plan"). As of April 23, 2008, a total of 250,500 shares of the Company's common stock were then subject to outstanding awards granted under the 2006 Plan, and an additional 49,500 shares of the Company's common stock were then available for new award grants under the 2006 Plan. The Company's outstanding options generally may not be transferred to third parties for value and do not include dividend equivalent rights.

        The Board of Directors approved the 2008 Plan based, in part, on a belief that the number of shares currently available under the 2006 Plan does not give the Company sufficient authority and flexibility to adequately provide for future incentives. If stockholders approve the 2008 Plan, no new awards will be granted under the 2006 Plan after the Annual Meeting. In that case, the number of shares of the Company's common stock that remain available for award grants under the 2006 Plan immediately prior to the Annual Meeting will become available for award grants under the 2008 Plan. An additional 450,000 shares of the Company's common stock will also be made available for award grants under the 2008 Plan, so if stockholders approve the 2008 Plan, a maximum of 499,500 shares will initially be available for award grants under that plan. In addition, if stockholders approve the 2008 Plan, any shares of common stock subject to stock option grants under the 2006 Plan that expire, are cancelled, or otherwise terminate after the Annual Meeting will also be available for award grant purposes under the 2008 Plan.

        If stockholders do not approve the 2008 Plan, the Company will continue to have the authority to grant awards under the 2006 Plan. If stockholders approve the 2008 Plan, the termination of our grant authority under the 2006 Plan will not affect awards then outstanding under that plan.

Summary Description of the 2008 Performance Incentive Plan

        The principal terms of the 2008 Plan are summarized below. The following summary is qualified in its entirety by the full text of the 2008 Plan, which appears as Exhibit I to this Proxy Statement.

        Purpose.    The purpose of the 2008 Plan is to promote the success of the Company and the interests of our stockholders by providing an additional means for us to attract, motivate, retain and reward directors, officers, employees and other eligible persons through the grant of awards and incentives for high levels of individual performance and improved financial performance of the Company. Equity-based awards are also intended to further align the interests of award recipients and our stockholders.

        Administration.    Our Board of Directors or one or more committees appointed by our Board of Directors will administer the 2008 Plan. Our Board of Directors has delegated general administrative authority for the 2008 Plan to the Compensation Committee. A committee may delegate some or all of its authority with respect to the 2008 Plan to another committee of directors, and certain limited

15


authority to grant awards to employees may be delegated to one or more officers of the Company. (The appropriate acting body, be it the Board of Directors, a committee within its delegated authority, or an officer within his or her delegated authority, is referred to in this proposal as the "Administrator").

        The Administrator has broad authority under the 2008 Plan with respect to award grants including, without limitation, the authority:

        No Repricing.    In no case (except due to an adjustment to reflect a stock split or similar event or any repricing that may be approved by stockholders) will any adjustment be made to a stock option or stock appreciation right award under the 2008 Plan (by amendment, cancellation and regrant, exchange or other means) that would constitute a repricing of the per share exercise or base price of the award.

        Eligibility.    Persons eligible to receive awards under the 2008 Plan include officers or employees of the Company or any of its subsidiaries, directors of the Company, and certain consultants and advisors to the Company or any of its subsidiaries. As of March 28, 2008, approximately 507 officers and employees of the Company and its subsidiaries (including all of the Company's named executive officers), and each of the Company's six directors who are not currently employees, are considered eligible under the 2008 Plan.

        Authorized Shares; Limits on Awards.    The maximum number of shares of the Company's common stock that may be issued or transferred pursuant to awards under the 2008 Plan equals the sum of: (1) 450,000 shares, plus (2) the number of shares available for additional award grant purposes under the 2006 Plan as of the date of the Annual Meeting and determined immediately prior to the termination of the authority to grant new awards under that plan as of the date of the Annual Meeting, plus (3) the number of any shares subject to stock options granted under the 2006 Plan and outstanding as of the date of the Annual Meeting which expire, or for any reason are cancelled or terminated, after the date of the Annual Meeting without being exercised. As of March 10, 2008, approximately 49,500 shares were available for additional award grant purposes under the 2006 Plan, and approximately 250,500 shares were subject to awards then outstanding under the 2006 Plan. As noted above, no additional awards will be granted under the 2006 Plan if stockholders approve the 2008 Plan.

16

        The following other limits are also contained in the 2008 Plan:

        To the extent that an award is settled in cash or a form other than shares, the shares that would have been delivered had there been no such cash or other settlement will not be counted against the shares available for issuance under the 2008 Plan. In the event that shares are delivered in respect of a dividend equivalent right, only the actual number of shares delivered with respect to the award shall be counted against the share limits of the 2008 Plan. To the extent that shares are delivered pursuant to the exercise of a stock appreciation right or stock option, the number of underlying shares as to which the exercise related shall be counted against the applicable share limits, as opposed to only counting the shares actually issued. (For purposes of clarity, if a stock appreciation right relates to 100,000 shares and is exercised at a time when the payment due to the participant is 15,000 shares, 100,000 shares shall be charged against the applicable share limits with respect to such exercise.) Shares that are subject to or underlie awards which expire or for any reason are cancelled or terminated, are forfeited, fail to vest, or for any other reason are not paid or delivered under the 2008 Plan will again be available for subsequent awards under the 2008 Plan. Shares that are exchanged by a participant or withheld by the Company to pay the exercise price of an award granted under the 2008 Plan, as well as any shares exchanged or withheld to satisfy the tax withholding obligations related to any award, will not be available for subsequent awards under the 2008 Plan. In addition, the 2008 Plan generally provides that shares issued in connection with awards that are granted by or become obligations of the Company through the assumption of awards (or in substitution for awards) in connection with an acquisition of another company will not count against the shares available for issuance under the 2008 Plan. The Company may not increase the applicable share limits of the 2008 Plan by repurchasing shares of common stock on the market (by using cash received through the exercise of stock options or otherwise).

        Types of Awards.    The 2008 Plan authorizes stock options, stock appreciation rights, restricted stock, stock bonuses and other forms of awards granted or denominated in the Company's common stock or units of the Company's common stock. The 2008 Plan retains flexibility to offer competitive incentives and to tailor benefits to specific needs and circumstances. Any award may be paid or settled in cash.

        A stock option is the right to purchase shares of the Company's common stock at a future date at a specified price per share (the "exercise price"). The per share exercise price of an option generally may not be less than the fair market value of a share of the Company's common stock on the date of grant. The maximum term of an option is ten years from the date of grant. An option may either be an incentive stock option or a nonqualified stock option. Incentive stock option benefits are taxed differently from nonqualified stock options, as described under "Federal Income Tax Consequences of Awards Under the 2008 Plan" below. Incentive stock options are also subject to more restrictive terms and are limited in amount by the Code and the 2008 Plan. Incentive stock options may only be granted to employees of the Company or a subsidiary.

17

        A stock appreciation right is the right to receive payment of an amount equal to the excess of the fair market value of a share of the Company's common stock on the date of exercise over the base price of the stock appreciation right. The base price will be established by the Administrator at the time of grant of the stock appreciation right and generally may not be less than the fair market value of a share of the Company's common stock on the date of grant. Stock appreciation rights may be granted in connection with other awards or independently. The maximum term of a stock appreciation right is ten years from the date of grant.

        The other types of awards that may be granted under the 2008 Plan include, without limitation, stock bonuses, restricted stock, performance stock, stock units, dividend equivalents, or similar rights to purchase or acquire shares.

        Performance-Based Awards.    The Administrator may grant awards that are intended to be performance- based awards within the meaning of Section 162(m) of the Code ("Performance-Based Awards"). Performance-Based Awards are in addition to any of the other types of awards that may be granted under the 2008 Plan (including options and stock appreciation rights which may also qualify as performance-based awards for Section 162(m) purposes). Performance-Based Awards may be in the form of restricted stock, performance stock, stock units, or other rights.

        The vesting or payment of Performance-Based Awards (other than options or stock appreciation rights) will depend on the absolute or relative performance of the Company on a consolidated, subsidiary, segment, division, or business unit basis. The Administrator will establish the criterion or criteria and target(s) on which performance will be measured. The Administrator must establish criteria and targets in advance of applicable deadlines under the Code and while the attainment of the performance targets remains substantially uncertain. The criteria that the Administrator may use for this purpose will include one or more of the following: earnings per share, cash flow (which means cash and cash equivalents derived from either net cash flow from operations or net cash flow from operations, financing and investing activities), total stockholder return, gross revenue, revenue growth, operating income (before or after taxes), net earnings (before or after interest, taxes, depreciation and/or amortization), return on equity or on assets or on net investment, cost containment or reduction, or any combination thereof. The performance measurement period with respect to an award may range from three months to ten years. Performance targets will be adjusted to mitigate the unbudgeted impact of material, unusual or nonrecurring gains and losses, accounting changes or other extraordinary events not foreseen at the time the targets were set unless the Administrator provides otherwise at the time of establishing the targets.

        Performance-Based Awards may be paid in stock or in cash (in either case, subject to the limits described under the heading "Authorized Shares; Limits on Awards" above). Before any Performance-Based Award (other than an option or stock appreciation right) is paid, the Administrator must certify that the performance targets have been satisfied. The Administrator has discretion to determine the performance targets and any other restrictions or other limitations of Performance-Based Awards and may reserve discretion to reduce payments below maximum award limits.

        Deferrals.    The Administrator may provide for the deferred payment of awards, and may determine the other terms applicable to deferrals. The Administrator may provide that deferred settlements include the payment or crediting of interest or other earnings on the deferred amounts, or the payment or crediting of dividend equivalents where the deferred amounts are denominated in shares.

        Assumption and Termination of Awards.    Generally, and subject to limited exceptions set forth in the 2008 Plan, if the Company dissolves or undergoes certain corporate transactions such as a merger, business combination, or other reorganization, or a sale of substantially all of its assets, all awards then-outstanding under the 2008 Plan will become fully vested or paid, as applicable, and will terminate

18


or be terminated in such circumstances, unless the Administrator provides for the assumption, substitution or other continuation of the award. The Administrator also has the discretion to establish other change in control provisions with respect to awards granted under the 2008 Plan. For example, the Administrator could provide for the acceleration of vesting or payment of an award in connection with a corporate event that is not described above and provide that any such acceleration shall be automatic upon the occurrence of any such event.

        Transfer Restrictions.    Subject to certain exceptions contained in Section 5.7 of the 2008 Plan, awards under the 2008 Plan generally are not transferable by the recipient other than by will or the laws of descent and distribution and are generally exercisable, during the recipient's lifetime, only by the recipient. Any amounts payable or shares issuable pursuant to an award generally will be paid only to the recipient or the recipient's beneficiary or representative. The Administrator has discretion, however, to establish written conditions and procedures for the transfer of awards to other persons or entities, provided that such transfers comply with applicable federal and state securities laws and, with limited exceptions set forth in the 2008 Plan, are not made for value.

        Adjustments.    As is customary in incentive plans of this nature, each share limit and the number and kind of shares available under the 2008 Plan and any outstanding awards, as well as the exercise or purchase prices of awards, and performance targets under certain types of Performance-Based Awards, are subject to adjustment in the event of certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends, or other similar events that change the number or kind of shares outstanding, and extraordinary dividends or distributions of property to the stockholders.

        No Limit on Other Authority.    Except as expressly provided with respect to the termination of the authority to grant new awards under the 2006 Plan if stockholders approve the 2008 Plan, the 2008 Plan does not limit the authority of the Board of Directors or any committee to grant awards or authorize any other compensation, with or without reference to the Company's common stock, under any other plan or authority.

        Termination of or Changes to the 2008 Plan.    The Board of Directors may amend or terminate the 2008 Plan at any time and in any manner. Stockholder approval for an amendment will be required only to the extent then required by applicable law or any applicable listing agency or required under Sections 162, 422 or 424 of the Code to preserve the intended tax consequences of the plan. For example, stockholder approval will be required for any amendment that proposes to increase the maximum number of shares that may be delivered with respect to awards granted under the 2008 Plan. (Adjustments as a result of stock splits or similar events will not, however, be considered an amendment requiring stockholder approval.) Unless terminated earlier by the Board of Directors, the authority to grant new awards under the 2008 Plan will terminate on March 9, 2018. Outstanding awards, as well as the Administrator's authority with respect thereto, generally will continue following the expiration or termination of the plan. Generally speaking, outstanding awards may be amended by the Administrator (except for a repricing), but the consent of the award holder is required if the amendment (or any plan amendment) materially and adversely affects the holder.

Federal Income Tax Consequences of Awards under the 2008 Plan

        The U.S. federal income tax consequences of the 2008 Plan under current federal law, which is subject to change, are summarized in the following discussion of the general tax principles applicable to the 2008 Plan. This summary is not intended to be exhaustive and, among other considerations, does not describe the deferred compensation provisions of Section 409A of the Code to the extent an award is subject to and does not satisfy those rules, nor does it describe state, local, or international tax consequences.

19

        With respect to nonqualified stock options, the company is generally entitled to deduct and the participant recognizes taxable income in an amount equal to the difference between the option exercise price and the fair market value of the shares at the time of exercise. With respect to incentive stock options, the company is generally not entitled to a deduction nor does the participant recognize income at the time of exercise, although the participant may be subject to the U.S. federal alternative minimum tax.

        The current federal income tax consequences of other awards authorized under the 2008 Plan generally follow certain basic patterns: nontransferable restricted stock subject to a substantial risk of forfeiture results in income recognition equal to the excess of the fair market value over the price paid (if any) only at the time the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant); bonuses, stock appreciation rights, stock-based performance awards, dividend equivalents, stock units, and other types of awards are generally subject to tax at the time of payment; and compensation otherwise effectively deferred is taxed when paid. In each of the foregoing cases, the company will generally have a corresponding deduction at the time the participant recognizes income.

        If an award is accelerated under the 2008 Plan in connection with a "change in control" (as this term is used under the Code), the company may not be permitted to deduct the portion of the compensation attributable to the acceleration if it exceeds certain threshold limits under the Code (and certain related excise taxes may be triggered). Furthermore, the aggregate compensation in excess of $1,000,000 attributable to awards that are not "performance-based" within the meaning of Section 162(m) of the Code may not be permitted to be deducted by the company in certain circumstances.

Specific Benefits under the 2008 Performance Incentive Plan

        The Company has not approved any awards that are conditioned upon stockholder approval of the 2008 Plan. The Company is not currently considering any specific award grants under the 2008 Plan. If the 2008 Plan had been in existence in fiscal 2007, the Company expects that its award grants for fiscal 2007 would not have been substantially different from those actually made in that year under the 2006 Plan. For information regarding stock-based awards granted to the Company's named executive officers during fiscal 2007, see the material under the heading "Executive Compensation".

        The closing market price for a share of the Company's common stock as of April 23, 2008 was $5.91 per share.

Vote Required for Approval of the 2008 Performance Incentive Plan

        The Board of Directors believes that the adoption of the 2008 Plan will promote the interests of the Company and its stockholders and will help the Company and its subsidiaries continue to be able to attract, retain and reward persons important to our success. All members of the Board of Directors are eligible for awards under the 2008 Plan and thus have a personal interest in the approval of the 2008 Plan.

        Approval of the 2008 Plan requires the affirmative vote of a majority of the common stock present, or represented, and entitled to vote at the Annual Meeting.

        THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" APPROVAL OF THE 2008 PERFORMANCE INCENTIVE PLAN AS DESCRIBED ABOVE AND SET FORTH IN EXHIBIT I HERETO. PROXIES RECEIVED WILL BE VOTED "FOR" APPROVAL UNLESS STOCKHOLDERS SPECIFY OTHERWISE IN THE PROXY.

EQUITY COMPENSATION PLAN INFORMATION

Stockholders are also being asked to approve a new equity compensation plan, the 2008 Plan that our board adopted in March 2008, as described above under "Proposal 3: Approval of the Willdan Group, Inc. 2008 Performance Incentive Plan".

        The following table sets forth, for our equity compensation plans, the number of shares of common stock subject to outstanding options, the weighted-average exercise price of outstanding options, and the number of shares remaining available for future award grants under all of our plans as of December 28, 2007.

The amounts reported under "Option Awards" reflect the aggregate dollar amounts recognized for option awards for financial statement reporting purposes with respect to fiscal 2007 and 2006 (disregarding any estimate of forfeitures related to service-based vesting conditions). Detailed information about the specific awards is reported in the table under "Outstanding Equity Awards at Fiscal 2007 Year-End" below. For a discussion of the assumptions and methodologies used to calculate the amounts reported in this column, please see the discussion of stock option awards granted during fiscal 2007 and 2006 contained in Note 5 (Stock Options) to our consolidated financial statements, included as part of our 2007 Annual Report filed on Form 10-K.

(5)
Mr. Lenocker resigned from our Board of Directors and served as our interim Chief Executive Officer and President from February 8, 2007 to April 2, 2007. On April 2, 2007, our board re-appointed Mr. Lenocker to the Board of Directors and to the Compensation Committee and Nominating and Governance Committee of the Board of Directors. In connection with Mr. Lenocker's term as interim Chief Executive Officer and President, he was granted a special option award in the amount of 5,000 shares that vested immediately on the grant date of August 2, 2007. For fiscal 2007, an expense of $20,071 was recognized for financial statement reporting purposes for this stock option award. Mr. Lenocker also received awards of 2,000 stock options as a Non-Employee Director in each of June 2007 and November 2006. For fiscal 2007 and fiscal 2006, expenses of $8,689 and $1,303, respectively, were recognized for financial statement reporting purposes for these stock option awards. Mr. Lenocker also received $54,692 and $70,249 as fees earned for serving on the Board of Directors in fiscal 2007 and fiscal 2006, respectively.

        During fiscal 2007, Dr. Brisbin, Mr. Lenocker and Mr. Westfall served on the Board of Directors. As employee-directors, Dr. Brisbin and Mr. Westfall did not receive additional compensation for their services as directors during fiscal 2007. Since Mr. Lenocker only served on the Board of Directors at times when he was not also an employee, he did receive compensation for his services as a director during fiscal 2007.

        The Summary Compensation Table above quantifies the value of the different forms of compensation earned by or awarded to our Named Officers in fiscal 2007 and 2006. The primary elements of each Named Officer's total compensation reported in the table are base salary and, for certain Named Officers, an annual bonus and a long-term equity incentive award consisting of stock options. Named Officers also earned or were paid the other benefits listed in the "All Other Compensation" column of the Summary Compensation Table, as further described in footnote (3) to the table.

        The Summary Compensation Table should be read in conjunction with the tables and narrative descriptions that follow. A description of the material terms of each Named Officer's base salary and annual bonus is provided immediately following this paragraph. The "Grants of Plan-Based Awards in Fiscal 2007" table, and the description of the material terms of the stock options granted in fiscal 2007 that follows it, provides information regarding the long-term equity incentives awarded to certain Named Officers in fiscal 2007. The "Outstanding Equity Awards at Fiscal 2007 Year-End" table and "Option Exercises and Stock Vested in Fiscal 2007" narrative provide further information on the Named Officers' potential realizable value and actual value realized with respect to their equity awards. The discussion of the potential payments due upon a termination of employment or change in control that follows is intended to further explain the potential future payments that are, or may become, payable to our Named Officers under certain circumstances.

        We have entered into employment agreements with Dr. Brisbin, our President and Chief Executive Officer, Ms. Gant, our Senior Vice President and Chief Financial Officer, Ms. McCamant, our Senior Vice President and Chief Operations Officer and Mr. Westfall, our Chairman of the Board. Mr. Westfall's employment agreement expired on December 31, 2007. These employment agreements, including the salary and bonus terms of such agreements, are described below.

26

        On April 2, 2007, we entered into an employment agreement with Dr. Brisbin. This agreement provides for an employment term of three years, with the agreement automatically renewable for successive one-year terms unless either party gives written notice not less than 60 days prior to expiration. The agreement provides that Dr. Brisbin will receive an initial annual base salary of $250,000 for the first year of employment. Thereafter, the board of directors will review Dr. Brisbin's base salary at least annually and may increase, but not decrease, the salary then in effect based on such review. Dr. Brisbin is also eligible to receive an annual discretionary bonus up to $250,000 in his first year of employment and an amount determined by the Board for each year of employment thereafter based on the achievement of performance targets established by the Board. The agreement also provides that Dr. Brisbin will be eligible for all standard company pension and welfare benefit programs in accordance with those generally afforded our employees and an automobile allowance of $900 per month. If Dr. Brisbin's employment is terminated by us without cause or by Dr. Brisbin for good reason (as those terms are defined in the agreement), Dr. Brisbin will receive severance compensation in an amount equal to his then-current annual base salary through the end of the term of his employment agreement plus health benefits for such period. However, if Dr. Brisbin breaches his non-competition or non-solicitation obligations under his employment agreement at any time, he will no longer be entitled to receive any unpaid severance benefits.

        On July 23, 2007, we entered into an employment agreement with Ms. Gant. This agreement provides for an employment term through December 31, 2008, with the agreement automatically extending on an at-will basis until terminated by us or Ms. Gant. The agreement provides that Ms. Gant will receive an annual base salary of $200,000 through December 31, 2008. Our board of directors will review Ms. Gant's base salary at least annually thereafter and may increase, but not decrease, the salary then in effect based on such review. Ms. Gant also is eligible to receive an annual discretionary bonus of up to 50% of her base salary as determined by the Board for each twelve-month period based on performance targets established by the Board. The agreement also provides that Ms. Gant will be eligible for all standard company pension and welfare benefit programs in accordance with those generally afforded our employees and an automobile allowance of $940 per month. If Ms. Gant's employment is terminated by us without cause or by Ms. Gant for good reason (as those terms are defined in the agreement), Ms. Gant will receive severance compensation in an amount equal to her then-current annual base salary through the date that is the later of six months from the date that her employment agreement is terminated and December 31, 2008, plus health benefits for such period. However, if Ms. Gant breaches her non-competition or non-solicitation obligations under her employment agreement at any time, she will no longer be entitled to receive any unpaid severance benefits.

        On July 23, 2007, we entered into a new employment agreement with Ms. McCamant. This agreement supersedes in its entirety the prior employment agreement between us and Ms. McCamant and provides for an initial employment term through December 31, 2008, with the agreement automatically extending on an at-will basis until terminated by us or Ms. McCamant. The agreement provides that Ms. McCamant will receive an annual base salary of $205,000 through December 31, 2008. We will review Ms. McCamant's base salary at least annually thereafter and may increase, but not decrease, the salary then in effect based on such review. Ms. McCamant also is eligible to receive an annual discretionary bonus of up to 50% of her base salary as determined by the Board for each twelve-month period based on performance targets established by the Board. The agreement also provides that Ms. McCamant will be eligible for all standard company pension and welfare benefit programs in accordance with those generally afforded our employees and an automobile allowance of $940 per month. If Ms. McCamant's employment is terminated by us without cause or by Ms. McCamant for good reason (as those terms are defined in the agreement), Ms. McCamant will receive severance compensation in an amount equal to her then-current annual base salary through the date that is the later of six months from the date that her employment agreement is terminated and December 31, 2008, plus health benefits for such period. However, if Ms. McCamant breaches her

27


non-competition or non-solicitation obligations under her employment agreement at any time, she will no longer be entitled to receive any unpaid severance benefits.

        On November 22, 2006, the Compensation Committee approved the payment of a discretionary cash bonus in the amount of $100,000 to Ms. McCamant in recognition of her work in managing our initial public offering process from commencement through its successful completion. The bonus was paid in December 2006. The remaining $33,000 received by Ms. McCamant in fiscal 2006 was a discretionary bonus unrelated to her work on the initial public offering process.

        On March 29, 2007, we entered into an employment agreement with Mr. Westfall that provided for an employment term expiring on December 31, 2007. The agreement provided for an annualized base salary of $215,000 and for the payment of a cash bonus equal to $202,500 as a result of Mr. Westfall being employed by us on April 1, 2007. Mr. Westfall also received use of a Toyota Highlander through the end of his employment with us, at which time the automobile was conveyed to Mr. Westfall free of all encumbrances. The agreement did not provide for any severance benefits (other than continued medical and dental benefits).

The options granted to Dr. Brisbin, Ms. Gant and Ms. McCamant in fiscal 2007 were granted with a per-share exercise price equal to the closing market price of the Company's common stock on the Nasdaq Global Market on the grant date. These stock options vest equally over three (3) years from the grant date and have a term of ten (10) years. Outstanding options, however, may terminate earlier than their stated expiration date in connection with a change in control transaction or a termination of the Named Officer's employment. The Named Officer will generally have three (3) months to exercise the stock option following a termination of employment. This period is extended to twelve (12) months if the Named Officer dies or terminates his or her employment because of a disability incurred while employed by

28

the Company. However, if a Named Officer's employment is terminated by the Company for cause, outstanding stock options (whether vested or unvested) will immediately terminate. The stock options granted to Named Officers during 2007 do not include any dividend or dividend equivalent rights.

        As indicated above, the stock options granted were granted under, and are subject to the terms of, the Company's 2006 Stock Incentive Plan. The plan is administered by the Compensation Committee. The Compensation Committee has authority to interpret the plan provisions and make all required determinations under the plan. This authority includes making required proportionate adjustments to outstanding awards upon the occurrence of certain corporate events such as reorganizations, mergers and stock splits, and making provision to ensure that any tax withholding obligations incurred in respect of awards are satisfied. Awards granted under the plan are generally only transferable to a beneficiary of a Named Officer upon his or her death. However, the Compensation Committee may establish procedures for the transfer of awards to other persons or entities, provided that such transfers comply with applicable securities laws and, with limited exceptions set forth in the plan document, are not made for value.

        Under the terms of the 2006 Stock Incentive Plan, if there is a change in control of the Company, each Named Officer's outstanding equity-based awards granted under the plan will generally become fully vested and exercisable to the extent such outstanding awards are not substituted or assumed in connection with the transaction. Any options that become vested in connection with a change in control generally must be exercised prior to the change in control, or they will be canceled in exchange for the right to receive a cash payment in connection with the change in control transaction.

Outstanding Equity Awards at Fiscal 2007 Year-End

        The following table presents information regarding the outstanding option awards held by each Named Officer as of December 28, 2007. These stock options were granted under the 2006 Plan. No Named Officer held any outstanding stock awards as of December 28, 2007.

Option Exercises and Stock Vested in Fiscal 2007

        Our Named Officers did not exercise any stock options during fiscal 2007. No stock awards have ever been granted to our Named Officers.

Retirement Benefits

        The Company provides retirement benefits to the Named Officers under the terms of its tax-qualified 401(k) plan. In fiscal 2007, the Company made a matching contribution on behalf of each participant equal to 25% of the first $4,000 of compensation contributed to the plan by the participant. These Company contributions function as a retention incentive as they vest ratably over the first four (4) years of service (as determined under the plan) with the Company. The Named Officers participate in the plan on substantially the same terms as our other participating employees. The Company does not maintain any deferred compensation, defined benefit or supplemental retirement plans for its Named Officers.

Potential Payments Upon Termination or Change in Control

        We do not provide special change in control benefits to our Named Officers and none of our employment agreements contain such a provision. Our only change in control arrangement applies to all of our employees who are eligible to participate in our 2006 Plan, and our 2008 Plan, if adopted. Upon a change in control, all outstanding options will vest immediately and become fully exercisable. The employment agreements for Dr. Brisbin, Ms. McCamant and Ms. Gant also provide for severance benefits upon termination by us without cause or by the Named Officer for good reason, each as described below.

        Brisbin.    If Dr. Brisbin's employment is terminated by us without cause or by Dr. Brisbin for good reason (as those terms are defined in the agreement), Dr. Brisbin will receive severance compensation in an amount equal to his then-current annual base salary through the end of the term of his employment agreement plus health benefits for such period. However, if Dr. Brisbin breaches his non-competition or non-solicitation obligations under his employment agreement at any time, he will no longer be entitled to receive any unpaid severance benefits. Had Dr. Brisbin's employment been terminated by us without cause or by Dr. Brisbin for good reason on December 28, 2007, Dr. Brisbin would have been entitled to full pay and benefits through April 2, 2010, the value of which we estimate at approximately $582,203.

        McCamant.    If Ms. McCamant's employment is terminated by us without cause or by Ms. McCamant for good reason (as those terms are defined in the agreement), Ms. McCamant will receive severance compensation in an amount equal to her then-current annual base salary through the date that is the later of six months from the date that her employment agreement is terminated and December 31, 2008, plus health benefits for such period. However, if Ms. McCamant breaches her non-competition or non-solicitation obligations under her employment agreement at any time, she will no longer be entitled to receive any unpaid severance benefits. Had Ms. McCamant's employment been terminated by us without cause or by Ms. McCamant for good reason on December 28, 2007, Ms. McCamant would have been entitled to full pay and benefits through June 28, 2008, the value of which we estimate at approximately $107,655.

        Gant.    If Ms. Gant's employment is terminated by us without cause or by Ms. Gant for good reason (as those terms are defined in the agreement), Ms. Gant will receive severance compensation in an amount equal to her then-current annual base salary through the date that is the later of six months

30


from the date that her employment agreement is terminated and December 31, 2008, plus health benefits for such period. However, if Ms. Gant breaches her non-competition or non-solicitation obligations under her employment agreement at any time, she will no longer be entitled to receive any unpaid severance benefits. Had Ms. Gant's employment been terminated by us without cause or by Ms. Gant for good reason on December 28, 2007, Ms. Gant would have been entitled to full pay and benefits through June 28, 2008, the value of which we estimate at approximately $104,445.

Related Person Transactions

        The following provides a description of certain relationships and related transactions since the beginning of fiscal year 2006 between some of our directors and executive officers and us or our subsidiaries and affiliates.

        Tax Agreements.    In connection with our initial public offering in November 2006, we entered into a Tax Agreement Relating to S Corporation Distributions with each of our stockholders, including our Chairman of the Board, Mr. Westfall, our Chief Operations Officer, Ms. McCamant, and our directors, Mrs. Heil and Mr. Lenocker. Pursuant to these agreements, we agreed to indemnify, defend and hold harmless each stockholder on an after-tax basis against additional income taxes, plus interest and penalties resulting from adjustments made, as a result of a final determination made by a competent tax authority, to the taxable income we reported as an S Corporation. Such indemnification also includes any losses, costs or expenses, including reasonable attorneys' fees, arising out of a claim for such tax liability.

        Lifetime Medical Benefits.    On May 19, 2006, our board of directors approved the extension of lifetime medical benefits to our director, Mrs. Heil, and our Chairman of the Board, Mr. Westfall, and his spouse, Patricia Westfall. Mrs. Heil's eligible dependents are included through the maximum age allowable under our benefits plan. We paid premiums for these medical benefits in the amount of $14,080 in fiscal 2007 for Ms. Heil and her eligible dependents. Mr. Westfall was an employee throughout fiscal 2007 so his medical benefits were paid through standard payroll deductions.

        Indemnification Agreement.    In connection with our initial public offering in November 2006, we entered into an Indemnification Agreement with our director, Mrs. Heil, as trustee of The 1994 Dan W. Heil and Linda Lee Heil Revocable Trust, the selling stockholder in the initial public offering. Pursuant to this agreement, we agreed to indemnify the selling stockholder against certain liabilities, including liabilities under the Securities Act of 1933, and to contribute to payments that the selling stockholder may be required to make for certain liabilities.

Related Person Transaction Policy

        In March 2007, the Board adopted a policy addressing the Company's procedures with respect to the review, approval and ratification of "related person transactions" that are required to be disclosed pursuant to Item 404(a) of Regulation S-K. The policy provides that any transaction, arrangement or relationship, or any series of similar transactions, in which the Company was, is or will be a participant, the amount involved exceeds $120,000, and a "related person" (as defined in the policy) has or will have a direct or indirect material interest (each such transaction, a "Related Person Transaction") shall be subject to review and approval or ratification by the Audit Committee. In its review of Related Person Transactions, the Audit Committee shall review the material facts and circumstances of the transaction and shall take into account certain factors, where appropriate, based on the particular facts and circumstances, including (i) the nature of the "related person's" interest in the transaction, (ii) the approximate dollar value of the amount involved in the Related Person Transaction, (iii) whether the transaction was taken in the Company's ordinary course of business, (iv) whether the transaction with the "related person" is proposed to be, or was, entered into on terms no less favorable to the Company

31


than terms that could have been reached with an unrelated third party and (v) the purpose of, and the potential benefits to the Company of, the Related Person Transaction.

        No member of the Audit Committee may participate in the review, approval or ratification of a transaction with respect to which he or she is a "related person" provided that such member can be counted for purposes of a quorum and shall provide such information with respect to the transaction as may be reasonably requested by other members of the Committee or the Board.


REPORT OF THE AUDIT COMMITTEE

        The Audit Committee of the Board of Directors assists the Board in performing its oversight responsibilities for the Company's financial reporting process, audit process and internal controls as more fully described in the Audit Committee's Charter. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls. The independent registered public accounting firm is responsible for auditing the Company's financial statements and expressing an opinion as to their conformity to U.S. generally accepted accounting principles.

        In the performance of its oversight function, the Audit Committee reviewed and discussed the Company's audited financial statements for the year ended December 28, 2007 with the Company's management and with the Company's independent registered public accounting firm. In addition, the Committee discussed with the Company's independent registered public accounting firm the matters required to be discussed by Statement of Auditing Standards No. 114 (Codification of Statements on Auditing Standards) which includes, among other items, matters related to the conduct of the audit of the Company's financial statements. The Committee has also received and reviewed the written disclosures and the letter from the Company's independent registered public accounting firm required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees) and discussed with the independent registered public accounting firm their independence from the Company.

        Based on the review and discussions with management and the independent registered public accounting firm described above, the Audit 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 28, 2007 for filing with the SEC.

Members of the Audit Committee

        The preceding Report of the Audit Committee shall not be deemed filed under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent the Company specifically incorporates this Report by reference into a filing under either of such Acts. The Report shall not be deemed soliciting material, or subject to Regulation 14A or 14C or the liabilities of Section 18 of the Securities Exchange Act.

OTHER INFORMATION

Solicitation of Proxies

        The cost of solicitation of Proxies in the form enclosed herewith will be paid by the Company. Solicitation will be made primarily by mail, but regular employees of the Company, without additional remuneration, may solicit Proxies by telephone, e-mail, facsimile and personal interviews. In addition, U.S. Stock Transfer Corporation will assist in solicitation of proxies. The Company anticipates out-of-pocket costs associated with proxy solicitation. The Company will also request persons, firms and corporations holding shares in their names or in the names of their nominees, which are beneficially owned by others, to send proxy materials to and obtain Proxies from such beneficial owners. The Company will reimburse such holders for their reasonable expenses.

Householding of Stockholder Materials

        Some banks, brokers and other nominee record holders may be participating in the practice of "householding" proxy statements and annual reports. This means that only one copy of the Company's Proxy Statement or Annual Report may have been sent to multiple stockholders in the same household unless the Company has received contrary instructions from one or more of the stockholders. The Company will promptly deliver a separate copy of either document to any stockholder upon request by writing to the Company at the following address: Willdan Group, Inc., 2401 East Katella Avenue, Suite 300, Anaheim, California 92806, Attn: Assistant Secretary or upon oral request directed to the Company's Assistant Secretary at (800) 424-9144. Any stockholder who wants to receive separate copies of the annual report and proxy statement in the future, or who is currently receiving multiple copies and would like to receive only one copy for his or her household, should contact the stockholder's bank, broker, or other nominee record holder, or contact the Company by writing to the above address or by oral request at the above telephone number.

Stockholder Proposals

        A stockholder proposal submitted pursuant to Rule 14a-8 under the Exchange Act for inclusion in the Company's proxy statement and form of Proxy for the 2009 annual meeting of stockholders must be received by the Company by December 15, 2008. Such a proposal must also comply with the requirements as to form and substance established by the SEC for such proposals. A stockholder otherwise desiring to bring a proposal before the 2009 annual meeting of stockholders (including generally any proposal relating to the nomination of a director to be elected to the Board of Directors) must comply with the then current advance notice and information requirements in the Company's Charter and Bylaws and deliver the proposal to the principal executive offices of the Company after March 10, 2009 and on or before April 9, 2009 (60 to 90 days prior to the first anniversary of this year's annual meeting) in order for such proposal to be considered timely. Any proposal nominating a director candidate must also comply with the requirements above under "Proposal 1. Election of Directors—The Board of Directors—Director Nominations by Stockholders." Any such proposal should be mailed to: Willdan Group, Inc., 2401 East Katella Avenue, Suite 300, Anaheim, California 92806, Attn: Assistant Secretary. Copies of the Charter and Bylaws may be obtained without charge by providing a written request to the Assistant Secretary of the Company at that address.

Section 16(a) Beneficial Ownership Reporting Compliance

        Section 16(a) of the Exchange Act requires our executive officers and directors, and persons who own more than 10% of a registered class of our equity securities, to file reports of ownership and changes in ownership with the SEC and the Nasdaq Global Market. Officers, directors and greater than 10% stockholders are required by the SEC's regulations to furnish us with copies of all Section 16(a) forms they file. Based solely on our review of the copies of such reports furnished to us, the following

33


officers, directors and greater than 10% stockholders failed to file certain reports required by Section 16(a) of the Exchange Act on a timely basis.

        Mr. Toups had one late filing of Form 4 that did not timely report one transaction. Mr. Toups reported a June 11, 2007 grant of options to purchase our common stock on July 3, 2007.

        To our knowledge, based solely on our review of the copies of such reports furnished to us, all other Section 16(a) filing requirements applicable to our executive officers, directors and greater than 10% beneficial owners were satisfied.

Exhibit I


WILLDAN GROUP, INC.
2008 PERFORMANCE INCENTIVE PLAN

1.     PURPOSE OF PLAN

        The purpose of this Willdan Group, Inc. 2008 Performance Incentive Plan (this "Plan") of Willdan Group, Inc., a Delaware corporation (the "Corporation"), is to promote the success of the Corporation and to increase stockholder value by providing an additional means through the grant of awards to attract, motivate, retain and reward selected employees and other eligible persons.

2.     ELIGIBILITY

        The Administrator (as such term is defined in Section 3.1) may grant awards under this Plan only to those persons that the Administrator determines to be Eligible Persons. An "Eligible Person" is any person who is either: (a) an officer (whether or not a director) or employee of the Corporation or one of its Subsidiaries; (b) a director of the Corporation or one of its Subsidiaries; or (c) an individual consultant or advisor who renders or has rendered bona fide services (other than services in connection with the offering or sale of securities of the Corporation or one of its Subsidiaries in a capital-raising transaction or as a market maker or promoter of securities of the Corporation or one of its Subsidiaries) to the Corporation or one of its Subsidiaries and who is selected to participate in this Plan by the Administrator; provided, however, that a person who is otherwise an Eligible Person under clause (c) above may participate in this Plan only if such participation would not adversely affect either the Corporation's eligibility to use Form S-8 to register under the Securities Act of 1933, as amended (the "Securities Act"), the offering and sale of shares issuable under this Plan by the Corporation or the Corporation's compliance with any other applicable laws. An Eligible Person who has been granted an award (a "participant") may, if otherwise eligible, be granted additional awards if the Administrator shall so determine. As used herein, "Subsidiary" means any corporation or other entity a majority of whose outstanding voting stock or voting power is beneficially owned directly or indirectly by the Corporation; and "Board" means the Board of Directors of the Corporation.

3.     PLAN ADMINISTRATION

        3.1    The Administrator.    This Plan shall be administered by and all awards under this Plan shall be authorized by the Administrator. The "Administrator" means the Board or one or more committees appointed by the Board or another committee (within its delegated authority) to administer all or certain aspects of this Plan. Any such committee shall be comprised solely of one or more directors or such number of directors as may be required under applicable law. A committee may delegate some or all of its authority to another committee so constituted. The Board or a committee comprised solely of directors may also delegate, to the extent permitted by Section 157(c) of the Delaware General Corporation Law and any other applicable law, to one or more officers of the Corporation, its powers under this Plan (a) to designate the officers and employees of the Corporation and its Subsidiaries who will receive grants of awards under this Plan, and (b) to determine the number of shares subject to, and the other terms and conditions of, such awards. The Board may delegate different levels of authority to different committees with administrative and grant authority under this Plan. Unless otherwise provided in the Bylaws of the Corporation or the applicable charter of any Administrator: (a) a majority of the members of the acting Administrator shall constitute a quorum, and (b) the vote of a majority of the members present assuming the presence of a quorum or the unanimous written consent of the members of the Administrator shall constitute action by the acting Administrator.

        With respect to awards intended to satisfy the requirements for performance-based compensation under Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), this Plan shall be administered by a committee consisting solely of two or more outside directors (as this requirement is applied under Section 162(m) of the Code); provided, however, that the failure to satisfy such requirement shall not affect the validity of the action of any committee otherwise duly authorized and


acting in the matter. Award grants, and transactions in or involving awards, intended to be exempt under Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), must be duly and timely authorized by the Board or a committee consisting solely of two or more non-employee directors (as this requirement is applied under Rule 16b-3 promulgated under the Exchange Act). To the extent required by any applicable listing agency, this Plan shall be administered by a committee composed entirely of independent directors (within the meaning of the applicable listing agency).

        3.2    Powers of the Administrator.    Subject to the express provisions of this Plan, the Administrator is authorized and empowered to do all things necessary or desirable in connection with the authorization of awards and the administration of this Plan (in the case of a committee or delegation to one or more officers, within the authority delegated to that committee or person(s)), including, without limitation, the authority to:

2


        3.3    Binding Determinations.    Any action taken by, or inaction of, the Corporation, any Subsidiary, or the Administrator relating or pursuant to this Plan and within its authority hereunder or under applicable law shall be within the absolute discretion of that entity or body and shall be conclusive and binding upon all persons. Neither the Board nor any Board committee, nor any member thereof or person acting at the direction thereof, shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with this Plan (or any award made under this Plan), and all such persons shall be entitled to indemnification and reimbursement by the Corporation in respect of any claim, loss, damage or expense (including, without limitation, attorneys' fees) arising or resulting therefrom to the fullest extent permitted by law and/or under any directors and officers liability insurance coverage that may be in effect from time to time.

        3.4    Reliance on Experts.    In making any determination or in taking or not taking any action under this Plan, the Administrator may obtain and may rely upon the advice of experts, including employees and professional advisors to the Corporation. No director, officer or agent of the Corporation or any of its Subsidiaries shall be liable for any such action or determination taken or made or omitted in good faith.

        3.5    Delegation.    The Administrator may delegate ministerial, non-discretionary functions to individuals who are officers or employees of the Corporation or any of its Subsidiaries or to third parties.

4.     SHARES OF COMMON STOCK SUBJECT TO THE PLAN; SHARE LIMITS

        4.1    Shares Available.    Subject to the provisions of Section 7.1, the capital stock that may be delivered under this Plan shall be shares of the Corporation's authorized but unissued Common Stock and any shares of its Common Stock held as treasury shares. For purposes of this Plan, "Common Stock" shall mean the common stock of the Corporation and such other securities or property as may become the subject of awards under this Plan, or may become subject to such awards, pursuant to an adjustment made under Section 7.1.

        4.2    Share Limits.    The maximum number of shares of Common Stock that may be delivered pursuant to awards granted to Eligible Persons under this Plan (the "Share Limit") is equal to the sum of the following:

3

        The following limits also apply with respect to awards granted under this Plan:


        Each of the foregoing numerical limits is subject to adjustment as contemplated by Section 4.3, Section 7.1, and Section 8.10.

        4.3    Awards Settled in Cash, Reissue of Awards and Shares.    To the extent that an award granted under this Plan is settled in cash or a form other than shares of Common Stock, the shares that would have been delivered had there been no such cash or other settlement shall not be counted against the shares available for issuance under this Plan. In the event that shares of Common Stock are delivered in respect of a dividend equivalent right granted under this Plan, only the actual number of shares delivered with respect to the award shall be counted against the share limits of this Plan. To the extent that shares of Common Stock are delivered pursuant to the exercise of a stock appreciation right or stock option granted under this Plan, the number of underlying shares as to which the exercise related shall be counted against the applicable share limits under Section 4.2, as opposed to only counting the shares actually issued. (For purposes of clarity, if a stock appreciation right relates to 100,000 shares and is exercised at a time when the payment due to the participant is 15,000 shares, 100,000 shares shall be charged against the applicable share limits under Section 4.2 with respect to such exercise.) Shares that are subject to or underlie awards granted under this Plan which expire or for any reason are cancelled or terminated, are forfeited, fail to vest, or for any other reason are not paid or delivered under this Plan shall again be available for subsequent awards under this Plan. Shares that are exchanged by a participant or withheld by the Corporation as full or partial payment in connection with any award under this Plan, as well as any shares exchanged by a participant or withheld by the Corporation or one of its Subsidiaries to satisfy the tax withholding obligations related to any award, shall not be available for subsequent awards under this Plan. Refer to Section 8.10 for application of the foregoing share limits with respect to assumed awards. The foregoing adjustments to the share limits of this Plan are subject to any applicable limitations under Section 162(m) of the Code with respect to awards intended as performance-based compensation thereunder.

        4.4    Reservation of Shares; No Fractional Shares; Minimum Issue.    The Corporation shall at all times reserve a number of shares of Common Stock sufficient to cover the Corporation's obligations and contingent obligations to deliver shares with respect to awards then outstanding under this Plan (exclusive of any dividend equivalent obligations to the extent the Corporation has the right to settle such rights in cash). No fractional shares shall be delivered under this Plan. The Administrator may pay

4


cash in lieu of any fractional shares in settlements of awards under this Plan. No fewer than 100 shares may be purchased on exercise of any award (or, in the case of stock appreciation or purchase rights, no fewer than 100 rights may be exercised at any one time) unless the total number purchased or exercised is the total number at the time available for purchase or exercise under the award.

5.     AWARDS

        5.1    Type and Form of Awards.    The Administrator shall determine the type or types of award(s) to be made to each selected Eligible Person. Awards may be granted singly, in combination or in tandem. Awards also may be made in combination or in tandem with, in replacement of, as alternatives to, or as the payment form for grants or rights under any other employee or compensation plan of the Corporation or one of its Subsidiaries. The types of awards that may be granted under this Plan are:

5

        5.2    Section 162(m) Performance-Based Awards.    Without limiting the generality of the foregoing, any of the types of awards listed in Section 5.1.4 above may be, and options and SARs granted to officers and employees ("Qualifying Options" and "Qualifying SARS," respectively) typically will be, granted as awards intended to satisfy the requirements for "performance-based compensation" within the meaning of Section 162(m) of the Code ("Performance-Based Awards"). The grant, vesting, exercisability or payment of Performance-Based Awards may depend (or, in the case of Qualifying Options or Qualifying SARs, may also depend) on the degree of achievement of one or more performance goals relative to a pre-established targeted level or level using one or more of the Business Criteria set forth below (on an absolute or relative basis) for the Corporation on a consolidated basis or for one or more of the Corporation's subsidiaries, segments, divisions or business units, or any combination of the foregoing. Any Qualifying Option or Qualifying SAR shall be subject only to the requirements of Section 5.2.1 and 5.2.3 in order for such award to satisfy the requirements for "performance-based compensation" under Section 162(m) of the Code. Any other Performance-Based Award shall be subject to all of the following provisions of this Section 5.2.

6

        5.3    Award Agreements.    Each award shall be evidenced by either (1) a written award agreement in a form approved by the Administrator and executed by the Corporation by an officer duly authorized to act on its behalf, or (2) an electronic notice of award grant in a form approved by the Administrator and recorded by the Corporation (or its designee) in an electronic recordkeeping system used for the purpose of tracking award grants under this Plan generally (in each case, an "award agreement"), as the Administrator may provide and, in each case and if required by the Administrator, executed or otherwise electronically accepted by the recipient of the award in such form and manner as the Administrator may require. The Administrator may authorize any officer of the Corporation (other than the particular award recipient) to execute any or all award agreements on behalf of the Corporation. The award agreement shall set forth the material terms and conditions of the award as established by the Administrator consistent with the express limitations of this Plan.

        5.4    Deferrals and Settlements.    Payment of awards may be in the form of cash, Common Stock, other awards or combinations thereof as the Administrator shall determine, and with such restrictions as it may impose. The Administrator may also require or permit participants to elect to defer the issuance of shares or the settlement of awards in cash under such rules and procedures as it may establish under this Plan. The Administrator may also provide that deferred settlements include the payment or crediting of interest or other earnings on the deferral amounts, or the payment or crediting of dividend equivalents where the deferred amounts are denominated in shares.

        5.5    Consideration for Common Stock or Awards.    The purchase price for any award granted under this Plan or the Common Stock to be delivered pursuant to an award, as applicable, may be paid by

7


means of any lawful consideration as determined by the Administrator, including, without limitation, one or a combination of the following methods:

        In no event shall any shares newly-issued by the Corporation be issued for less than the minimum lawful consideration for such shares or for consideration other than consideration permitted by applicable state law. Shares of Common Stock used to satisfy the exercise price of an option shall be valued at their fair market value on the date of exercise. The Corporation will not be obligated to deliver any shares unless and until it receives full payment of the exercise or purchase price therefor and any related withholding obligations under Section 8.5 and any other conditions to exercise or purchase have been satisfied. Unless otherwise expressly provided in the applicable award agreement, the Administrator may at any time eliminate or limit a participant's ability to pay the purchase or exercise price of any award or shares by any method other than cash payment to the Corporation.

        5.6    Definition of Fair Market Value.    For purposes of this Plan, "fair market value" shall mean, unless otherwise determined or provided by the Administrator in the circumstances, the last price (in regular trading) for a share of Common Stock as furnished by the National Association of Securities Dealers, Inc. (the "NASD") through the NASDAQ Global Market Reporting System (the "Global Market") for the date in question or, if no sales of Common Stock were reported by the NASD on the Global Market on that date, the last price (in regular trading) for a share of Common Stock as furnished by the NASD through the Global Market for the next preceding day on which sales of Common Stock were reported by the NASD. The Administrator may, however, provide with respect to one or more awards that the fair market value shall equal the last price (in regular trading) for a share of Common Stock as furnished by the NASD through the Global Market on the last trading day preceding the date in question or the average of the high and low trading prices of a share of Common Stock as furnished by the NASD through the Global Market for the date in question or the most recent trading day. If the Common Stock is no longer listed or is no longer actively traded on the Global Market as of the applicable date, the fair market value of the Common Stock shall be the value as reasonably determined by the Administrator for purposes of the award in the circumstances. The Administrator also may adopt a different methodology for determining fair market value with respect to one or more awards if a different methodology is necessary or advisable to secure any intended favorable tax, legal or other treatment for the particular award(s) (for example, and without limitation, the Administrator may provide that fair market value for purposes of one or more awards will be based on an average of closing prices (or the average of high and low daily trading prices) for a specified period preceding the relevant date).

        5.7    Transfer Restrictions.    

8

        5.8    International Awards.    One or more awards may be granted to Eligible Persons who provide services to the Corporation or one of its Subsidiaries outside of the United States. Any awards granted to such persons may be granted pursuant to the terms and conditions of any applicable sub-plans, if any, appended to this Plan and approved by the Administrator.

6.     EFFECT OF TERMINATION OF EMPLOYMENT OR SERVICE ON AWARDS

        6.1    General.    The Administrator shall establish the effect of a termination of employment or service on the rights and benefits under each award under this Plan and in so doing may make distinctions based upon, inter alia, the cause of termination and type of award. If the participant is not an employee of the Corporation or one of its Subsidiaries and provides other services to the Corporation or one of its Subsidiaries, the Administrator shall be the sole judge for purposes of this Plan (unless a contract or the award otherwise provides) of whether the participant continues to render services to the Corporation or one of its Subsidiaries and the date, if any, upon which such services shall be deemed to have terminated.

        6.2    Events Not Deemed Terminations of Service.    Unless the express policy of the Corporation or one of its Subsidiaries, or the Administrator, otherwise provides, the employment relationship shall not be considered terminated in the case of (a) sick leave, (b) military leave, or (c) any other leave of absence authorized by the Corporation or one of its Subsidiaries, or the Administrator; provided that, unless reemployment upon the expiration of such leave is guaranteed by contract or law or the Administrator otherwise provides, such leave is for a period of not more than three months. In the case of any employee of the Corporation or one of its Subsidiaries on an approved leave of absence,

9


continued vesting of the award while on leave from the employ of the Corporation or one of its Subsidiaries may be suspended until the employee returns to service, unless the Administrator otherwise provides or applicable law otherwise requires. In no event shall an award be exercised after the expiration of the term set forth in the applicable award agreement.

        6.3    Effect of Change of Subsidiary Status.    For purposes of this Plan and any award, if an entity ceases to be a Subsidiary of the Corporation a termination of employment or service shall be deemed to have occurred with respect to each Eligible Person in respect of such Subsidiary who does not continue as an Eligible Person in respect of the Corporation or another Subsidiary that continues as such after giving effect to the transaction or other event giving rise to the change in status.

7.     ADJUSTMENTS; ACCELERATION

        7.1    Adjustments.    Subject to Section 7.2, upon (or, as may be necessary to effect the adjustment, immediately prior to): any reclassification, recapitalization, stock split (including a stock split in the form of a stock dividend) or reverse stock split; any merger, combination, consolidation, or other reorganization; any spin-off, split-up, or similar extraordinary dividend distribution in respect of the Common Stock; or any exchange of Common Stock or other securities of the Corporation, or any similar, unusual or extraordinary corporate transaction in respect of the Common Stock; then the Administrator shall equitably and proportionately adjust (1) the number and type of shares of Common Stock (or other securities) that thereafter may be made the subject of awards (including the specific share limits, maximums and numbers of shares set forth elsewhere in this Plan), (2) the number, amount and type of shares of Common Stock (or other securities or property) subject to any outstanding awards, (3) the grant, purchase, or exercise price (which term includes the base price of any SAR or similar right) of any outstanding awards, and/or (4) the securities, cash or other property deliverable upon exercise or payment of any outstanding awards, in each case to the extent necessary to preserve (but not increase) the level of incentives intended by this Plan and the then-outstanding awards.

        Unless otherwise expressly provided in the applicable award agreement, upon (or, as may be necessary to effect the adjustment, immediately prior to) any event or transaction described in the preceding paragraph or a sale of all or substantially all of the business or assets of the Corporation as an entirety, the Administrator shall equitably and proportionately adjust the performance standards applicable to any then-outstanding performance-based awards to the extent necessary to preserve (but not increase) the level of incentives intended by this Plan and the then-outstanding performance-based awards.

        It is intended that, if possible, any adjustments contemplated by the preceding two paragraphs be made in a manner that satisfies applicable U.S. legal, tax (including, without limitation and as applicable in the circumstances, Section 424 of the Code, Section 409A of the Code and Section 162(m) of the Code) and accounting (so as to not trigger any charge to earnings with respect to such adjustment) requirements.

        Without limiting the generality of Section 3.3, any good faith determination by the Administrator as to whether an adjustment is required in the circumstances pursuant to this Section 7.1, and the extent and nature of any such adjustment, shall be conclusive and binding on all persons.

        7.2    Corporate Transactions—Assumption and Termination of Awards.    Upon the occurrence of any of the following: any merger, combination, consolidation, or other reorganization; any exchange of Common Stock or other securities of the Corporation; a sale of all or substantially all the business, stock or assets of the Corporation; a dissolution of the Corporation; or any other event in which the Corporation does not survive (or does not survive as a public company in respect of its Common Stock); then the Administrator may make provision for a cash payment in settlement of, or for the assumption, substitution or exchange of any or all outstanding share-based awards or the cash,

10


securities or property deliverable to the holder of any or all outstanding share-based awards, based upon, to the extent relevant under the circumstances, the distribution or consideration payable to holders of the Common Stock upon or in respect of such event. Upon the occurrence of any event described in the preceding sentence, then, unless the Administrator has made a provision for the substitution, assumption, exchange or other continuation or settlement of the award or the award would otherwise continue in accordance with its terms in the circumstances: (1) subject to Section 7.4 and unless otherwise provided in the applicable award agreement, each then-outstanding option and SAR shall become fully vested, all shares of restricted stock then outstanding shall fully vest free of restrictions, and each other award granted under this Plan that is then outstanding shall become payable to the holder of such award; and (2) each award shall terminate upon the related event; provided that the holder of an option or SAR shall be given reasonable advance notice of the impending termination and a reasonable opportunity to exercise his or her outstanding vested options and SARs (after giving effect to any accelerated vesting required in the circumstances) in accordance with their terms before the termination of such awards (except that in no case shall more than ten days' notice of the impending termination be required and any acceleration of vesting and any exercise of any portion of an award that is so accelerated may be made contingent upon the actual occurrence of the event).

        Without limiting the preceding paragraph, in connection with any event referred to in the preceding paragraph or any change in control event defined in any applicable award agreement, the Administrator may, in its discretion, provide for the accelerated vesting of any award or awards as and to the extent determined by the Administrator in the circumstances.

        The Administrator may adopt such valuation methodologies for outstanding awards as it deems reasonable in the event of a cash or property settlement and, in the case of options, SARs or similar rights, but without limitation on other methodologies, may base such settlement solely upon the excess if any of the per share amount payable upon or in respect of such event over the exercise or base price of the award.

        In any of the events referred to in this Section 7.2, the Administrator may take such action contemplated by this Section 7.2 prior to such event (as opposed to on the occurrence of such event) to the extent that the Administrator deems the action necessary to permit the participant to realize the benefits intended to be conveyed with respect to the underlying shares. Without limiting the generality of the foregoing, the Administrator may deem an acceleration to occur immediately prior to the applicable event and/or reinstate the original terms of the award if an event giving rise to an acceleration does not occur.

        Without limiting the generality of Section 3.3, any good faith determination by the Administrator pursuant to its authority under this Section 7.2 shall be conclusive and binding on all persons.

        7.3    Other Acceleration Rules.    The Administrator may override the provisions of Section 7.2 and/or 7.4 by express provision in the award agreement and may accord any Eligible Person a right to refuse any acceleration, whether pursuant to the award agreement or otherwise, in such circumstances as the Administrator may approve. The portion of any ISO accelerated in connection with an event referred to in Section 7.2 (or such other circumstances as may trigger accelerated vesting of the award) shall remain exercisable as an ISO only to the extent the applicable $100,000 limitation on ISOs is not exceeded. To the extent exceeded, the accelerated portion of the option shall be exercisable as a nonqualified stock option under the Code.

        7.4    Golden Parachute Limitation.    Notwithstanding anything else contained in this Section 7 to the contrary, in no event shall any award or payment be accelerated under this Plan to an extent or in a manner so that such award or payment, together with any other compensation and benefits provided to, or for the benefit of, the participant under any other plan or agreement of the Corporation or any of its Subsidiaries, would not be fully deductible by the Corporation or one of its Subsidiaries for federal

11


income tax purposes because of Section 280G of the Code. If a participant would be entitled to benefits or payments hereunder and under any other plan or program that would constitute "parachute payments" as defined in Section 280G of the Code, then the participant may by written notice to the Corporation designate the order in which such parachute payments will be reduced or modified so that the Corporation or one of its Subsidiaries is not denied federal income tax deductions for any "parachute payments" because of Section 280G of the Code. Notwithstanding the foregoing, if a participant is a party to an employment or other agreement with the Corporation or one of its Subsidiaries, or is a participant in a severance program sponsored by the Corporation or one of its Subsidiaries, that contains express provisions regarding Section 280G and/or Section 4999 of the Code (or any similar successor provision), or the applicable award agreement includes such provisions, the Section 280G and/or Section 4999 provisions of such employment or other agreement or plan, as applicable, shall control as to the awards held by that participant (for example, and without limitation, a participant may be a party to an employment agreement with the Corporation or one of its Subsidiaries that provides for a "gross-up" as opposed to a "cut-back" in the event that the Section 280G thresholds are reached or exceeded in connection with a change in control and, in such event, the Section 280G and/or Section 4999 provisions of such employment agreement shall control as to any awards held by that participant).

8.     OTHER PROVISIONS

        8.1    Compliance with Laws.    This Plan, the granting and vesting of awards under this Plan, the offer, issuance and delivery of shares of Common Stock, and/or the payment of money under this Plan or under awards are subject to compliance with all applicable federal and state laws, rules and regulations (including but not limited to state and federal securities law and federal margin requirements) and to such approvals by any listing, regulatory or governmental authority as may, in the opinion of counsel for the Corporation, be necessary or advisable in connection therewith. The person acquiring any securities under this Plan will, if requested by the Corporation or one of its Subsidiaries, provide such assurances and representations to the Corporation or one of its Subsidiaries as the Administrator may deem necessary or desirable to assure compliance with all applicable legal and accounting requirements.

        8.2    No Rights to Award.    No person shall have any claim or rights to be granted an award (or additional awards, as the case may be) under this Plan, subject to any express contractual rights (set forth in a document other than this Plan) to the contrary.

        8.3    No Employment/Service Contract.    Nothing contained in this Plan (or in any other documents under this Plan or in any award) shall confer upon any Eligible Person or other participant any right to continue in the employ or other service of the Corporation or one of its Subsidiaries, constitute any contract or agreement of employment or other service or affect an employee's status as an employee at will, nor shall interfere in any way with the right of the Corporation or one of its Subsidiaries to change a person's compensation or other benefits, or to terminate his or her employment or other service, with or without cause. Nothing in this Section 8.3, however, is intended to adversely affect any express independent right of such person under a separate employment or service contract other than an award agreement.

        8.4    Plan Not Funded.    Awards payable under this Plan shall be payable in shares or from the general assets of the Corporation, and no special or separate reserve, fund or deposit shall be made to assure payment of such awards. No participant, beneficiary or other person shall have any right, title or interest in any fund or in any specific asset (including shares of Common Stock, except as expressly otherwise provided) of the Corporation or one of its Subsidiaries by reason of any award hereunder. Neither the provisions of this Plan (or of any related documents), nor the creation or adoption of this Plan, nor any action taken pursuant to the provisions of this Plan shall create, or be construed to create, a trust of any kind or a fiduciary relationship between the Corporation or one of its Subsidiaries

12


and any participant, beneficiary or other person. To the extent that a participant, beneficiary or other person acquires a right to receive payment pursuant to any award hereunder, such right shall be no greater than the right of any unsecured general creditor of the Corporation.

        8.5    Tax Withholding.    Upon any exercise, vesting, or payment of any award or upon the disposition of shares of Common Stock acquired pursuant to the exercise of an ISO prior to satisfaction of the holding period requirements of Section 422 of the Code, the Corporation or one of its Subsidiaries shall have the right at its option to:

        In any case where a tax is required to be withheld in connection with the delivery of shares of Common Stock under this Plan, the Administrator may in its sole discretion (subject to Section 8.1) require or grant (either at the time of the award or thereafter) to the participant the right to elect, pursuant to such rules and subject to such conditions as the Administrator may establish, that the Corporation reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of shares, valued in a consistent manner at their fair market value or at the sales price in accordance with authorized procedures for cashless exercises, necessary to satisfy the minimum applicable withholding obligation on exercise, vesting or payment. In no event shall the shares withheld exceed the minimum whole number of shares required for tax withholding under applicable law.

        8.6    Effective Date, Termination and Suspension, Amendments.    

13

        8.7    Privileges of Stock Ownership.    Except as otherwise expressly authorized by the Administrator, a participant shall not be entitled to any privilege of stock ownership as to any shares of Common Stock not actually delivered to and held of record by the participant. Except as expressly required by Section 7.1 or otherwise expressly provided by the Administrator, no adjustment will be made for dividends or other rights as a stockholder for which a record date is prior to such date of delivery.

        8.8    Governing Law; Construction; Severability.    

        8.9    Captions.    Captions and headings are given to the sections and subsections of this Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of this Plan or any provision thereof.

14

        8.10    Stock-Based Awards in Substitution for Stock Options or Awards Granted by Other Corporation.    Awards may be granted to Eligible Persons in substitution for or in connection with an assumption of employee stock options, SARs, restricted stock or other stock-based awards granted by other entities to persons who are or who will become Eligible Persons in respect of the Corporation or one of its Subsidiaries, in connection with a distribution, merger or other reorganization by or with the granting entity or an affiliated entity, or the acquisition by the Corporation or one of its Subsidiaries, directly or indirectly, of all or a substantial part of the stock or assets of the employing entity. The awards so granted need not comply with other specific terms of this Plan, provided the awards reflect only adjustments giving effect to the assumption or substitution consistent with the conversion applicable to the Common Stock in the transaction and any change in the issuer of the security. Any shares that are delivered and any awards that are granted by, or become obligations of, the Corporation, as a result of the assumption by the Corporation of, or in substitution for, outstanding awards previously granted by an acquired company (or previously granted by a predecessor employer (or direct or indirect parent thereof) in the case of persons that become employed by the Corporation or one of its Subsidiaries in connection with a business or asset acquisition or similar transaction) shall not be counted against the Share Limit or other limits on the number of shares available for issuance under this Plan.

        8.11    Non-Exclusivity of Plan.    Nothing in this Plan shall limit or be deemed to limit the authority of the Board or the Administrator to grant awards or authorize any other compensation, with or without reference to the Common Stock, under any other plan or authority.

        8.12    No Corporate Action Restriction.    The existence of this Plan, the award agreements and the awards granted hereunder shall not limit, affect or restrict in any way the right or power of the Board or the stockholders of the Corporation to make or authorize: (a) any adjustment, recapitalization, reorganization or other change in the capital structure or business of the Corporation or any Subsidiary, (b) any merger, amalgamation, consolidation or change in the ownership of the Corporation or any Subsidiary, (c) any issue of bonds, debentures, capital, preferred or prior preference stock ahead of or affecting the capital stock (or the rights thereof) of the Corporation or any Subsidiary, (d) any dissolution or liquidation of the Corporation or any Subsidiary, (e) any sale or transfer of all or any part of the assets or business of the Corporation or any Subsidiary, or (f) any other corporate act or proceeding by the Corporation or any Subsidiary. No participant, beneficiary or any other person shall have any claim under any award or award agreement against any member of the Board or the Administrator, or the Corporation or any employees, officers or agents of the Corporation or any Subsidiary, as a result of any such action.

        8.13    Other Company Benefit and Compensation Programs.    Payments and other benefits received by a participant under an award made pursuant to this Plan shall not be deemed a part of a participant's compensation for purposes of the determination of benefits under any other employee welfare or benefit plans or arrangements, if any, provided by the Corporation or any Subsidiary, except where the Administrator expressly otherwise provides or authorizes in writing. Awards under this Plan may be made in addition to, in combination with, as alternatives to or in payment of grants, awards or commitments under any other plans or arrangements of the Corporation or its Subsidiaries.
