AIRGAS, INC.

PROXY STATEMENT

     This Proxy Statement is furnished in connection with the solicitation of proxies at the direction of the Board of Directors of Airgas, Inc. (the “Company”) for use at the Annual Meeting of Stockholders to be held on August 4, 2004.

     Stockholders of record at the close of business on June 21, 2004, will be entitled to vote at the Annual Meeting. At the close of business on June 21, 2004, 76,924,992 shares of the Company’s $0.01 par value common stock (“Common Stock”) were outstanding and entitled to vote. A stockholder is entitled to one vote for each share of Common Stock held by such stockholder. This Proxy Statement and the enclosed form of proxy are being mailed to the Company’s stockholders on or about June 28, 2004.

     Shares represented by a proxy in the accompanying form, unless previously revoked, will be voted at the meeting if the proxy is returned to the Company properly executed and in sufficient time to permit the necessary examination and tabulation before a vote is taken. A proxy may be revoked at any time prior to its exercise by giving written notice to the Secretary of the Company, by giving a later dated proxy, or by voting in person at the meeting. Mere attendance at the Annual Meeting will not revoke the proxy. Any specific instructions indicated on your proxy will be followed. Unless record holders indicate otherwise on their proxy cards, their shares will be voted FOR each of the Company’s proposals 1, 2 and 3, and at the discretion of the proxy holders on such other business as may properly come before the Annual Meeting. Shares held by brokers for beneficial owners will be voted as described below. The Board of Directors unanimously recommends that you vote to approve each of the Company’s proposals.

     Abstentions are counted as shares present for purposes of determining the presence or absence of a quorum for the transaction of business, but are not counted as shares voted in favor of a proposal and therefore have the effect of a vote against proposals 2 and 3. Brokers holding shares for beneficial owners must vote their shares according to the specific instructions they receive from the owners. If specific instructions are not received, brokers may vote these shares at their discretion, except if they are precluded from exercising their voting discretion on certain proposals pursuant to the rules of the New York Stock Exchange (the “NYSE”). In such a case, the broker may not vote on the proposal absent specific voting instructions. This results in what is known as a “broker non-vote.” A broker non-vote has the effect of a negative vote when a majority of the shares issued and outstanding is required for approval of the proposal. A broker non-vote has the effect of reducing the number of required affirmative votes when a majority of the shares present and entitled to vote is required for approval of the proposal.

     The election of each nominee for director (Proposal 1) requires a plurality of votes cast. Brokers have discretionary authority to vote on this proposal. Approval of the amendment to the 1997 Directors’ Stock Option Plan (Proposal 2) and ratification of the selection of the Company’s independent registered public accounting firm (Proposal 3) require the approval of a majority of the outstanding shares of Common Stock present and entitled to vote at the meeting. In addition, to satisfy the listing requirements of the NYSE, the amendment to the 1997 Directors’ Stock Option Plan must be approved by a majority of votes cast on the Proposal at the meeting, provided that the total votes cast represent greater than 50% of the shares entitled to vote on the Proposal. Under the NYSE rules, brokers may not vote shares on Proposal 2 absent instructions from the stockholders. Without stockholder instructions, a broker non-vote will occur. Brokers are not precluded from voting on Proposal 3, and therefore there will be no broker non-votes on that proposal.

 


Table of Contents

     The cost of proxy solicitation, including the cost of reimbursing banks and brokers for forwarding proxies and proxy statements to beneficial owners of the Common Stock, will be paid by the Company. Proxies will be solicited without extra compensation by some of the officers and other employees of the Company by mail and, if found to be necessary, by telephone and personal interviews. The Company has also retained Georgeson Shareholder Communications, Inc. to assist in the solicitation of proxies at an anticipated fee of $6,500 plus out-of-pocket expenses.

GOVERNANCE OF THE COMPANY

Corporate Governance Commitment

     The Company’s Board of Directors believes strongly that good corporate governance accompanies and greatly aids the Company’s long-term business success. This success has been the direct result of the Company’s key business strategies and the highest business standards. The Board strongly supports these key strategies, advising on design and implementation, and seeing that they guide the Company’s operations. To accomplish its strategic goals, the Company has, consistently over many years, developed and followed a program of corporate governance. The Board has adopted a set of Corporate Governance Guidelines, and its Governance and Compensation Committee is responsible for reviewing and reassessing the Guidelines on an annual basis and making recommendations to the Board concerning changes to the Guidelines. The Guidelines are published on the Company’s website at www.airgas.com. The Guidelines address the following matters.

Board Independence and Expertise

     Board and Committee Independence

     The Board of Directors is composed of independent outside directors, with the exception of the Chief Executive Officer. The committees of the Board are also composed of independent outside directors, with the exception of the Executive Committee, of which the Chief Executive Officer is a member.

     The Board of Directors has determined that the following directors and nominee for director, comprising all of the directors and nominees other than the Chief Executive Officer, are “independent” under the listing standards of the NYSE: William O. Albertini; W. Thacher Brown; Frank B. Foster, III; James W. Hovey; Paula A. Sneed; David M. Stout; Lee M. Thomas; Robert L. Yohe; and Richard C. Ill. In order to assist the Board in making this determination, the Board has adopted “Director Independence Standards,” which are attached hereto as Exhibit A. These standards identify material relationships that a director may have with the Company that would interfere with the director’s ability to exercise independent judgment. Each of the directors and the nominee identified above meets the standards set forth in the Director Independence Standards.

     Board Membership Criteria

     As the composition of the Board of Directors exemplifies, the Company values experience in business, educational achievement, moral and ethical character, diversity, skills, accountability and integrity, financial literacy, high performance standards and industry knowledge. The Governance and Compensation Committee is responsible for screening, selecting and recommending to the Board candidates for election as directors.

Table of Contents

     Audit Committee Independence

     The Board of Directors, in its business judgment, has determined that each of the members of the Audit Committee meets the independence requirements of the Securities and Exchange Commission (the “SEC”) and the NYSE. The Audit Committee regularly holds separate executive sessions with (i) the Company’s independent registered public accounting firm, without management present, (ii) the Company’s Chief Financial Officer and (iii) the Company’s chief internal auditor.

Director Nomination Process

     The Governance and Compensation Committee reviews possible candidates for the Board of Directors and recommends the nominees for directors to the Board of Directors for approval. The Board of Directors has adopted criteria for the selection of nominees to the Board of Directors, which is a part of the Company’s Corporate Governance Guidelines, which can also be found on the Company’s website. These criteria describe specific traits, abilities and experience that the Governance and Compensation Committee and the Board look for in determining candidates for election to the Board. The Governance and Compensation Committee considers suggestions from many sources, including stockholders, regarding possible candidates for directors. Such suggestions, together with a complete description of the nominee’s qualifications, experience and background, and a statement signed by the nominee in which he or she consents to such nomination and which includes the name of the stockholder making the suggestion and evidence of that person’s ownership of the Company’s stock, including the number of shares held and the length of time of ownership, should be submitted to the Secretary of the Company at 259 North Radnor-Chester Road, Suite 100, Radnor Pennsylvania 19087-5283 not less than 120 days prior to the anniversary date of the most recent annual meeting of stockholders, or if the meeting has been changed by more than 30 days from the date of the previous year’s meeting, not less than 60 days before the date of the meeting. Possible candidates who have been suggested by stockholders are evaluated by the Governance and Compensation Committee in the same manner as are other possible candidates.

     In addition to making suggestions to the Governance and Compensation Committee for the selection of nominees as described above, under the By-Laws, stockholders are also entitled to nominate persons for election as directors only if, among other things, written notice has been given, in the case of an annual meeting, not earlier than 120 days and not later than 90 days prior to the anniversary of the preceding year’s annual meeting. The notice must set forth information about the proposed nominee and the consent of the nominee, among other things.

Charters, Code of Ethics and Business Conduct Policy

     In addition to the Corporate Governance Guidelines, the Company maintains the following to support its corporate governance policies:

     Charters for Board Committees

     In 2003, the Governance and Compensation Committee and the Audit Committee, under the leadership of the respective committee chairs, reviewed their charters and recommended to the Board that revised charters be adopted. The Board adopted the revised charters reflecting the increased authority and responsibilities of the committees under new corporate governance rules adopted by the SEC and the NYSE.

Table of Contents

     Code of Ethics and Business Conduct Policy

     The Board sponsors the Company’s Code of Ethics and the Business Conduct Policy, which ensure that the Company’s business is conducted in a consistently legal and ethical manner. The Company’s General Counsel oversees compliance with the Code of Ethics and Business Conduct Policy. The Company’s Code of Ethics is available on the Company’s website at www.airgas.com. All of the Company’s employees, including its Chief Executive Officer, Chief Financial Officer and Controller, are required to comply with the Code of Ethics and the Business Conduct Policy. They cover all areas of professional conduct, including compliance with laws, conflicts of interest, confidentiality, corporate opportunities, use of Company assets and reporting illegal or unethical behavior. The Code of Ethics describes the Company’s procedures to receive, retain and address complaints regarding accounting, internal controls and auditing matters, and other illegal or unethical behavior.

Directors are Stockholders

     Meaningful Director Stock Ownership

     Board members are expected to develop a meaningful ownership position in Company stock. For more information on director stock ownership, please see the table included in “Security Ownership” on page 21. Board members receive stock options each year as a significant component of their overall compensation.

Direct Access to Management and Independent Advisors

     The Company provides directors with complete access to management. Key senior managers regularly attend Board meetings. Topics are presented to the Board by the members of management who are most knowledgeable about the issue at hand, irrespective of seniority, which allows dialogue to develop between directors and management. The Board and each of the Audit Committee and the Governance and Compensation Committee have the right to consult with and retain independent legal and other advisors at the Company’s expense.

Ensuring Management Accountability

     Performance-Based Compensation

     The Company has linked the pay of its managers and employees at all levels to the Company’s performance. As described in greater detail in the Governance and Compensation Committee Report on Executive Compensation included herein, the Governance and Compensation Committee adheres to this pay-for-performance philosophy, and stock-based incentives constitute a significant component of senior management’s overall compensation.

     CEO Evaluation Process

     The non-management members of the Board conduct an annual evaluation of the CEO’s performance and compensation. The CEO is evaluated against the goals set each year, including both objective measures and subjective criteria consistent with, and in furtherance of, the Company’s strategic goals and initiatives. As part of the overall evaluation process, the Board meets informally with the CEO to give and seek feedback on a regular basis. The non-management members of the Board meet in executive session to review the CEO’s performance.

Functioning of the Board

     Directorship Limits

     To devote sufficient time to properly discharge their duties, no director may serve on more than three other boards of public companies. Recognizing the value of continuity of directors who have experience with the Company, there are no limits on the number of terms for which a director may hold office. Directors are required to resign from the Board by the date of the annual meeting of stockholders in the year in which the director has his or her seventieth birthday.

     Attendance at Board and Stockholder Meetings

     Directors are expected to attend all meetings of the Board and Committees on which they serve and annual stockholder meetings. Each director attended 100 percent of the meetings of the Board and the Committees on which they served in fiscal 2004, except for one director who was unable to attend one Committee meeting during the fiscal year due to illness. All of the directors attended the last Annual Meeting.

     Executive Sessions; Stockholder Communications with the Board

     The Board holds two regularly scheduled executive sessions each year where non-management directors meet without management participation. In the event that one or more of the non-management directors do not qualify as independent directors, the Board will also hold at least one meeting each year of the independent directors. Interested persons may communicate directly and confidentially with the non-management directors by writing to the Acting Chairperson, Non-Management Directors, Airgas, Inc., 259 North Radnor-Chester Road, Suite 100, Radnor, Pennsylvannia 19087-5283. Each year, the Board selects the Acting Chairperson of the non-management directors who will preside at the executive sessions of the Board and with whom stockholders wishing to communicate with the non-management directors may communicate.

Assessing the Board’s Performance

     Board Evaluation Process

     The Board of Directors conducts an annual evaluation of itself and its committees. The directors first evaluate overall Board performance against certain criteria that the Board has determined are important to its success. These include financial oversight, succession planning, compensation, corporate governance, strategic planning and Board structure and role. The Board then reviews the results of the evaluation and discusses what, if any, action should be taken to improve its performance.

ELECTION OF DIRECTORS
(Proposal 1)

     The By-Laws of the Company presently provide that the Board of Directors shall designate the number of directors constituting the Board of Directors, which shall be no less than seven and no more than thirteen members. Currently, that number has been fixed by the Board of Directors at nine. The Board of Directors consists of three classes, with directors of one class to be elected each year, for terms extending to the annual meeting of stockholders held in the third year following the year of their election.

Compensation of Directors

     Directors who are not employees of the Company are paid an annual retainer of $12,000 plus a fee of $1,500 for each Board or Committee meeting attended, and are entitled to participate in the 1997 Directors’ Stock Option Plan (the “Directors’ Plan”).

     In order to closely align the interests of directors with those of stockholders, a majority of the directors’ compensation is in the form of stock options. The number of options granted is determined annually by the Governance and Compensation Committee. The exercise price of each option is equal to the fair market value of the Common Stock on the date of grant, and each option is exercisable immediately and has a term of 10 years. On July 29, 2003, each Board member was granted 7,500 options with an exercise price of $18.98 per share.

     The Chairmen of the Governance and Compensation Committee and the Finance Committee also receive an additional $3,000 annual retainer, and the Chairman of the Audit Committee receives an additional $5,000 annual retainer. Directors are also reimbursed for their travel expenses for attendance at Board and Committee meetings.

Section 16(a) Beneficial Ownership Reporting Compliance

     Section 16(a) of the Securities and Exchange Act of 1934 requires the Company’s officers and directors, and persons who own more than ten percent of a registered class of the Company’s equity securities, to file reports of ownership and changes in ownership of the securities with the SEC and the NYSE. Such persons are also required to furnish the Company with copies of all Section 16(a) forms they file. The Company is aware of one ten percent stockholder, who is also an officer and director, and his spouse.

     Based solely on its review of the copies of the forms received by it with respect to the 2004 fiscal year, or written representations from certain reporting persons, the Company believes that all of its officers and directors complied with all filing requirements applicable to them.

(1)   The Directors’ Plan, designed to provide equity compensation to directors of the Company who are not employees of the Company, authorizes the granting of stock options and restricted stock awards. As of March 31, 2004, no restricted stock awards have been granted under the Directors’ Plan. Restricted stock awards under the Directors’ Plan cannot exceed 100,000 shares in the aggregate, and restricted stock awards under the 1997 Stock Option Plan and the Directors’ Plan in any calendar year may not exceed, in the aggregate, 0.5% of shares of Common Stock of the Company issued and outstanding on any date of grant.
 
(2)   The 1997 Stock Option Plan (the “1997 Plan”), designed to provide equity compensation to certain employees and independent contractors of the Company, authorizes the granting of stock options and restricted stock awards. As of March 31, 2004, no restricted stock awards have been granted under the 1997 Plan. Restricted stock awards granted under the 1997 Plan cannot exceed 1,000,000 shares in the aggregate, and restricted stock awards under the 1997 Plan and the Directors’ Plan in any calendar year may not exceed, in the aggregate, 0.5% of shares of Common Stock of the Company issued and outstanding on any date of grant.

     exercise prices in excess of the fair market value on the date of grant, ranging from $11.98 to $18.78 per share).

Deferred Compensation Plan

     During the 2004 fiscal year, the Company offered eligible employees the opportunity to participate in the Company’s Deferred Compensation Plan. Under the plan, an eligible employee could elect to defer a specified percentage of his or her annual salary and/or bonus, and a director could elect to defer his or her annual compensation, by making a timely deferral election. Participants could choose to have amounts credited to a retirement account, to provide funds to the participant after retirement, and/or an in-service account, to provide funds to the participant while still employed by, or serving as a director of, the Company. Participants made elections as to how their deferred amounts would be deemed invested among several options available under the plan. The participant’s accounts were credited with earnings, gains and losses as if the amounts were actually invested in accordance with the participant’s investment elections. The Company’s obligations under the plan are unsecured general obligations to pay the compensation in the future in accordance with the terms of the plan. In May 2004, the Board of Directors authorized the discontinuance of further deferrals by participants under the plan after May 31, 2004 and the subsequent termination of the plan.

Termination of Employment and Change of Control Arrangements

     The Company has entered into “change-of-control” agreements (“Change-of-Control Agreements”) with Mr. McCausland, Mr. Fischer, Mr. Millay, Mr. Powers, Mr. Schulte and seven other key management personnel. The terms of the agreements are consistent with similar agreements used in other major U.S. public corporations and provide salary and benefit continuation if the executive is terminated upon a change-of-control. A change-of-control is defined to include events in which a party (other than Mr. McCausland) acquires 20% or more of the combined voting power of the Company’s then outstanding securities, or in which Mr. McCausland, together with all affiliates and associates, acquires 30% or more of the combined voting power of the Company’s then outstanding securities. Under the Change-of-Control Agreements, following the executive’s termination, he or she would be entitled to a lump sum payment equal to one to three times (depending upon the executive) the executive’s annual base salary at the time of termination, plus the executive’s potential bonus amount for the fiscal year in which the change-of-control occurred. The executive’s health and welfare benefits would also continue for two or three years, depending upon the executive, and the executive would be vested in all stock options and restricted stock. The cash and non-cash amounts payable under the Change-of-Control Agreements and under any other arrangements with the Company are limited to the maximum amount permitted without the imposition of an excise tax under the Internal Revenue Code. Generally, this would limit an executive’s lump sum payment to 2.99 times the executive’s average annual compensation for the preceding five years.

     In addition, under an arrangement entered into in 1992, in the event of the termination of Mr. McCausland’s employment for any reason including a change of control, Mr. McCausland is entitled to a payment equal to two times his annual salary, the continuation of health insurance and other employee benefits for a three-year period and automatic vesting of all of his stock options, subject to the above limitation of 2.99 times average annual compensation. The limitation under Mr. McCausland’s Change-of-Control Agreement would reduce the amount payable under his 1992 arrangement to the extent that the aggregate lump sum payments under the Change-of-Control Agreement and the 1992 arrangement exceed 2.99 times his average annual compensation for the preceding five years.

Certain Relationships and Related Transactions

     Since the beginning of its last fiscal year, the Company has not engaged in any transaction or series of similar transactions, or any proposed transaction or series of similar transactions, to which the Company or any of its subsidiaries was or is to be a party (1) in which the amount involved exceeds $60,000 and (2) in which any of the Company’s directors, nominees for director, executive officers or beneficial owners of more than 5% of its Common Stock, or members of the immediate families of those individuals, had or will have, a direct or indirect material interest.

     The Company does have business relationships with corporations or other organizations in which a director, nominee for director or executive officer of the Company may also be a director, executive officer, investor or trustee, or have some other similar direct or indirect relationship with the other corporation or organization. For example, the Company provides goods and services to companies such as Georgia-Pacific Corporation (of which Lee M. Thomas, a director of the Company, is President and Chief Operating Officer), GlaxoSmithKline (of which David M. Stout, a director of the Company, is President, Pharmaceuticals) and Kraft Foods, Inc. (of which Paula A. Sneed, a director of the Company, is Senior Vice President of Global Marketing Resources). In all instances, including those described above, the Company enters into these arrangements in the ordinary course of business and each party provides to or receives from the other the relevant goods and services on a non-exclusive basis at arms-length negotiated rates. In addition, none of the Company directors was directly involved with the negotiation or consummation of any such arrangement. While any revenue, profits or other aspects of a business relationship with the Company may, of course, affect the individual’s overall compensation or value of his or her investments in the other corporation or organization, the Company does not believe that in any of these cases the relevant Company director receives or has received any compensation from the other corporation that is directly linked to the Company-related business arrangement. None of these arrangements is material to the Company or the other corporation or organization involved, and the Company does not believe that any indirect interest that a Company director may have with respect to such an arrangement is material.

     In October 2000, the Company extended a loan to Mr. Fischer in the amount of $150,000 in connection with his relocation when he joined the Company. The loan was evidenced by a note bearing interest at an annual rate of 61/4% and providing for the payment of principal and interest in June 2003. The highest outstanding amount of the loan, including principal and accrued interest, during fiscal 2004 was $177,010. The loan was repaid in full by Mr. Fischer in June 2003.

GOVERNANCE AND COMPENSATION COMMITTEE REPORT ON
EXECUTIVE COMPENSATION

     The Governance and Compensation Committee of the Board of Directors has furnished the following report on executive compensation. Under the supervision of the Governance and Compensation Committee, the Company has developed and implemented compensation policies, plans and programs. The Committee is composed of three independent non-employee directors. Following review and approval by the Governance and Compensation Committee, all issues pertaining to executive compensation (other than the granting of stock options or restricted stock awards under the Company’s stock option plans and the establishment of performance goals under the Company’s management bonus plans) are submitted to the full Board of Directors for approval.

     Since its inception, the Company has maintained the philosophy that compensation of its entire management team, including executive officer level positions through operating management positions at

17


Table of Contents

the Company’s operating subsidiaries, should be directly and materially linked to operating performance. To achieve this linkage, compensation is heavily weighted towards bonuses paid on the basis of performance and towards the award of stock options to a relatively broad level of operating management associates.

Compensation Principles

     The foundation of the management compensation program is based on beliefs and guiding principles designed to align compensation with business strategy, Company values and management initiatives. The program:

    Rewards executives for long-term strategic management and the enhancement of stockholder value through the award of stock options as a significant percentage of total compensation;
 
    Integrates compensation programs with both the Company’s annual and longer-term strategic planning and measurement processes; and
 
    Provides flexibility in order to maximize local autonomy, which the Company views as an important element of its success.

Executive Compensation Program

     The total compensation program consists of both cash and equity-based compensation. The annual compensation consists of a base salary and an annual bonus under the Company’s management bonus plans. Incentive compensation is closely tied to corporate and individual performance in a manner that encourages a continuing focus on building sales, profitability and shareholder value. Periodically, the Committee determines the salary ranges for executive officers upon review of salary ranges in companies comparable in size in terms of annual sales. The comparison group includes companies in the specialty chemicals industry plus distribution companies outside of the Company’s industrial classification. The Committee includes companies outside of the Company’s industry in the comparison group because it believes that the Company is similar in certain respects to such companies. Actual salary changes are based upon individual and Company-wide performance, and total compensation levels generally are comparable to the median total compensation levels paid at companies in the comparison group. The individual’s performance is measured against specific management objectives, such as sales, EBITDA, operating profits, return on capital, safety targets, programs for training and development of personnel and sales and marketing programs.

     In addition to salary, there is the opportunity to earn significantly higher total compensation through incentive bonus and stock option programs. The bonus and stock option components are “at risk,” meaning that the ultimate value of the compensation depends on such factors as Company financial performance, individual performance and stock price. This at-risk portion of the Company’s executive compensation generally ranges from approximately 42% to 71% of total compensation. Awards for executive officers varied with a combination of the Company’s achievement of return on capital and earnings goals and were then adjusted up or down for the executive’s achievement of specified objectives and individual job performance. The objectives that the Committee considers are the same as those used to determine salary. The Committee relies on these quantitative and qualitative measures and it uses subjective judgment and discretion in light of these measures and the Company’s compensation principles described above to determine base salaries and bonuses.

     Long-term incentives are provided through the grant of stock options. The Committee reviews and approves the participation of executive officers of the Company and its subsidiaries under the Company’s

18


Table of Contents

stock option plan. The Committee has the authority to determine the individuals to whom stock options are awarded, the terms of the options and the number of shares subject to each option. In determining the total number of options to be granted, the Committee considers the percentage dilution of the grants and the value of the options using the Black-Scholes method. The size of the individual option grants is generally based upon position level. As with the determination of base salaries and bonuses, the Committee relies on quantitative and qualitative measures, exercising subjective judgment and discretion in view of these measures and the Company’s general policies. During fiscal 2004, the value of options granted was generally between 18% and 39% of an executive officer’s total compensation. Through grants of stock options, the objective of aligning executive officers’ long-range interests with those of the stockholders is met by providing the executive officers with the opportunity to build a meaningful stake in the Company. The Company strongly encourages senior management and executive officers to hold a meaningful equity interest in the Company, and, accordingly, has established stock ownership guidelines for such employees. The Company believes that such ownership better aligns the interests of management and stockholders. During fiscal 2004, executive officers could also participate in the Company’s Deferred Compensation Plan, under which the executive could elect to defer a portion of his or her salary and bonus, the Company’s 401(k) Plan, which includes Company matching contributions, and the Company’s Employee Stock Purchase Plan, which generally permits eligible employees to purchase shares of the Company’s Common Stock at a 15% discount from the market price.

Chief Executive Officer Compensation

     The Governance and Compensation Committee reviewed the Chief Executive Officer’s compensation for fiscal year 2004 and determined that his base salary would be $600,000. This base salary approximates the median level of chief executive officers of the comparison group of companies and is consistent with the Company’s objective of paying a higher level of compensation through its at-risk bonus and stock option programs. A fiscal year 2004 bonus of $650,000 was awarded to the Chief Executive Officer. This was determined based on the Company’s performance in attaining certain pre-established levels of objective earnings performance targets as set forth in the 2004 Executive Bonus Plan, and certain other operating objectives. In determining the number of shares to be awarded as stock options, the Committee considered the executive compensation paid by the comparison group of companies and the Chief Executive Officer’s performance.

Deductibility

The Committee’s policy is to pursue a compensation strategy which is performance-based, minimizing the non-deductibility of compensation for the Company’s executive officers under Section 162(m) of the Internal Revenue Code, while maintaining the flexibility of its compensation programs to attract and retain highly qualified executives in a competitive environment. Accordingly, the Committee may award non-deductible compensation when necessary to enable the Company to meet its overall objectives.

REPORT OF THE AUDIT COMMITTEE

     The Audit Committee reviewed and discussed the audited financial statements of the Company for the fiscal year ended March 31, 2004 with the Company’s management and with the independent registered public accounting firm. The Committee reviewed with the independent registered public accounting firm its judgment as to the quality of the Company’s application of U.S. generally accepted accounting principles and other such matters as required by Statement on Auditing Standards No. 61, “Communications with Audit Committees,” as amended.

     The Committee discussed with both the Company’s internal auditors and independent registered public accounting firm the overall scope and plans for their respective audits. The Committee periodically met with the internal auditors and the independent registered public accounting firm, with and without management present, to discuss the results of their examinations, evaluations of internal controls and overall quality of the Company’s financial reporting.

     The Committee has discussed with and received written disclosure and a letter from the independent registered public accounting firm as required by the Independence Standards Board’s Standard No. 1, “Independence Discussions with Audit Committees,” as amended, as to their independence from the Company and its management.

     Based on the reviews and discussions referred to above, the Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2004, for filing with the Securities and Exchange Commission. The Audit Committee also appointed, and the Board of Directors is proposing that the stockholders ratify the appointment of, KPMG LLP as the Company’s independent registered public accounting firm for the 2005 fiscal year.

PROPOSAL TO APPROVE AN AMENDMENT TO THE
1997 DIRECTORS’ STOCK OPTION PLAN
(Proposal 2)

     On May 15, 1997, the Board of Directors adopted, subject to stockholder approval, the 1997 Directors’ Stock Option Plan (the “Plan”). The text of the Plan, as proposed to be amended, is set forth in Appendix B to this Proxy Statement. The following summary is subject to, and qualified in its entirety by reference to, Appendix B.

     The Company relies on stock options as an essential component of the compensation packages necessary for the Company to attract and retain the services of highly qualified persons to serve as members of the Board of Directors. The Company believes that the granting of stock options to its non-employee directors will be beneficial to the Company and its stockholders, as a substantial portion of the compensation of its non-employee directors will be linked to the performance of the Company.

     As of March 31, 2004, 49,500 shares remain available for the future grant of stock options or restricted stock under the Plan. If the amendment to the Plan is not approved by the stockholders, the

23


Table of Contents

Company may be unable to continue to provide suitable long-term equity-based incentives to present and future non-employee directors.

Vote Required for Approval

     To be adopted, the amendment to the Plan (Proposal 2) must be approved by a majority of votes cast on the Proposal at the meeting, provided that the total votes cast represent greater than 50% of the shares entitled to vote on the Proposal.

The Board unanimously recommends a vote FOR the adoption of the amendment to the Plan.

Description of the Plan

     Eligibility

     Those persons who are non-employee directors of the Company are eligible to be selected by the Governance and Compensation Committee (the “Committee”) of the Board of Directors. In selecting participants, the Committee may consider the nature of the person’s services and responsibilities, the person’s present and potential contribution to the Company’s success and other factors it deems relevant.

     Types of Grants

     The Plan authorizes (i) the granting of nonqualified stock options (“Options”) to purchase shares of the Company’s Common Stock and (ii) the granting of shares of the Company’s Common Stock subject to conditions of forfeiture (“Restricted Stock Awards”).

     Administration

     The Plan is administered by the Committee which shall consist of at least two non-employee members of the Board of Directors. The Committee in its sole discretion determines the eligible persons to be awarded Options and Restricted Stock Awards, the number of shares subject thereto and the exercise price of Options, subject to certain limitations. In addition, the determinations and the interpretation and construction of any provision of the Plan by the Committee is final, binding and conclusive.

     Common Stock Subject to the Plan

     A total of 500,000 shares of Common Stock (subject to adjustment as discussed below) currently are reserved for issuance upon exercise of Options and Restricted Stock Awards granted under the Plan, provided that the Committee may not issue more than 100,000 shares as Restricted Stock Awards, and that Restricted Stock Awards under the Plan and the 1997 Stock Option Plan in any calendar year may not exceed, in the aggregate, 0.5% of the shares of Common Stock issued and outstanding on any date of grant.

     If the amendment to the Plan is approved by the stockholders, a total of 800,000 shares of Common Stock (subject to adjustment as discussed below) will be reserved for sale upon exercise of Options and Restricted Stock Awards under the Plan.

24


Table of Contents

     Granting of Options

     The Committee will grant Options and Restricted Stock Awards from time to time in its discretion. No determination has been made as to the number of Options that in the future may be allocated to the non-employee directors as a group, as a result of the adoption of the Plan.

     Exercise Price of Options

     Options may not be granted with an exercise price per share that is less than the closing price of a share of Common Stock at the date of grant.

     Payment of Exercise Price

     The exercise price of an Option may be paid in cash, by certified check, by the delivery of already owned Common Stock having a fair market value equal to the exercise price, by the use of the cashless exercise features of the Plan, or by such other mode of payment as the Committee may approve, provided, however, that if the optionee acquired such stock directly or indirectly from the Company, he shall have owned such stock to be surrendered for six months prior to tendering such stock for the exercise of an Option. The Committee may impose such limitations and prohibitions on the use of shares of Common Stock to pay the exercise price as it deems appropriate.

     Transferability of Options

     The Committee may grant Options that are transferable, without consideration, to immediate family members.

     Exercisability of Options

     Unless the Committee provides otherwise, and subject to stockholder approval, Options are exercisable in full on the date of grant. The Plan provides that upon the occurrence of certain changes in control, mergers or sales of substantially all of the assets of the Company, each Option that is not exercisable shall immediately become exercisable in full.

     Expiration of Options

     The expiration date of an Option is determined by the Committee at the time of the grant, but, unless otherwise provided by the Committee, Options will not be exercisable after the expiration of 10 years from the date of grant of the Option. Options generally terminate one year after termination of service due to death. Options terminate immediately if the Committee finds that the optionee has engaged in certain dishonest acts, has disclosed trade secrets or confidential information or has engaged in competition with the Company.

     As described below, an Option that is not exercisable in full becomes exercisable in full upon the occurrence of certain corporate transactions.

     Restricted Stock Awards

     A Restricted Stock Award is an award of Common Stock that vests at such time and in such installments as may be determined by the Committee, and until it vests, is subject to restrictions on transferability and to the possibility of forfeiture. In addition, each grant of Restricted Stock Awards will be subject to such other restrictions as are set by the Committee. If the Committee finds that the

25


Table of Contents

participant has engaged in certain dishonest acts, has disclosed trade secrets or confidential information or has engaged in competition with the Company, the nonvested shares will be forfeited, and all shares become nonforfeitable if a change in control occurs.

     Adjustments

     The Plan provides for adjustments to the number of shares under which Options may be granted, to the number of shares subject to outstanding Options and to the exercise price of such outstanding Options in the event of a declaration of a stock dividend or any recapitalization resulting in a stock split-up, combination or exchange of the Company’s Common Stock.

     Certain Corporate Transactions

     All outstanding Options that are not exercisable automatically become immediately exercisable upon a change in control, as defined in the Plan. In general, a change in control is deemed to have occurred when (1) a change in the majority of the Board of Directors occurs during any two-year period without the approval of a majority of directors in office at the beginning of such period, (2) any person or group, other than the Company, an affiliate, or an employee benefit plan, becomes the beneficial owner of securities representing more than 20% of combined voting power of Company’s outstanding securities, or (3) the stockholders approve a merger or other disposition of all or substantially all of the Company’s assets, if the Company’s stockholders immediately before the transaction own, immediately after such transaction, equity securities possessing less than 50% of the voting power of the surviving or acquiring corporation.

     Amendments; Term of Plan

     The Board may amend the Plan at any time subject to stockholder approval in certain instances. The Board may not amend the Plan without stockholder approval to increase the number of shares of Common Stock as to which Options or Restricted Stock Awards may be granted. No Options or Restricted Stock Awards may be granted under the Plan after May 15, 2007.

Federal Income Tax Consequences

     Grants of Options

     Under current tax laws, the grant of an Option will not be a taxable event to the recipient optionee and the Company will not be entitled to a deduction with respect to such grant.

     Exercise of Nonqualified Options and Subsequent Sale of Stock

     Upon the exercise of an Option, an optionee will recognize ordinary income at the time of exercise equal to the excess of the then fair market value of the Company’s Common Stock received over the exercise price. The taxable income recognized upon exercise of an Option will be treated as ordinary income and the Company will be entitled to deduct as compensation expense an amount equal to the ordinary income an optionee recognizes with respect to such exercise. When shares of the Common Stock received upon the exercise of an Option subsequently are sold or exchanged in a taxable transaction, the holder thereof generally will recognize capital gain (or loss) equal to the difference between the total amount realized and the fair market value of the Common Stock on the date of exercise; the character of such gain or loss as long-term or short-term capital gain or loss will depend upon the holding period of the shares following exercise.

26


Table of Contents

     Restricted Stock Awards

     The recipient of a Restricted Stock Award recognizes no income and the Company can take no deduction for federal income tax purposes when a Restricted Stock Award is granted, unless the recipient makes an election to recognize income on the date of grant. On the date of vesting of shares subject to a Restricted Stock Award (or if a participant so elects, on the date of grant), a participant will realize ordinary income in an amount equal to the fair market value of the shares on that date and the Company will be entitled to a deduction in the same amount. If a participant who elects to recognize income on the date of grant subsequently forfeits shares subject to the participant’s Restricted Stock Award, the participant will not be entitled to either a deduction for the amount previously recognized as income with respect to the forfeited shares or refund of any taxes paid thereon.

Plan Benefits to Non-Employee Directors

     As of the date hereof, there were eight non-employee directors who were eligible to receive Options and Restricted Stock Awards under the Plan. The grant of Options and Restricted Stock Awards under the Plan is subject to the discretion of the Committee. As of the date of this Proxy Statement, there has been no determination by the Committee with respect to future awards under the Plan. Accordingly, future awards are not determinable at this time. During fiscal year 2004, each of the non-employee directors received grants of options to acquire 7,500 shares of the Company’s Common Stock at an exercise price of $18.98 per share. No Restricted Stock Awards were granted during fiscal year 2004.

Stock Price Information

     The closing price of the Company’s Common Stock on the New York Stock Exchange on June 21, 2004 was $23.76.

PROPOSAL TO RATIFY INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
(Proposal 3)

     The Audit Committee of the Board of Directors has appointed the firm of KPMG LLP as the Company’s independent registered public accounting firm to audit the financial statements of the Company for the fiscal year ending March 31, 2005. The Board of Directors has proposed that the stockholders ratify the appointment of KPMG LLP. This firm audited the Company’s financial statements for the fiscal year ended March 31, 2004. Representatives of KPMG LLP are expected to attend the Annual Meeting, will have the opportunity to make a statement if they desire to do so, and are expected to be available to respond to appropriate questions.

Audit and Non-Audit Fees

     The following table shows the fees that the Company paid to the independent registered public accounting firm for services provided to the Company during the 2004 and 2003 fiscal years:

                 
    2004
  2003
Audit Fees
  $ 785,000     $ 620,000  
Audit-Related Fees
  $ 175,000     $ 25,000  
Tax Fees
  $ 85,000     $ 77,000  
All Other Fees
  $ 10,000     $  

27


Table of Contents

    Audit Fees consist of fees billed for professional services rendered for the audit of the Company’s annual financial statements and reviews of the financial statements included in the Company’s quarterly report on Forms 10-Q.
 
    Audit-Related Fees consist of services that are reasonably related to the performance of the audit or review of the Company’s financial statements and are not reported under “Audit Fees.” The services for the fees disclosed under this category for the 2004 and 2003 fiscal years include employee benefit plan audits. These 2004 fiscal year fees also include work performed relating to the issuance of senior subordinated debt and the adoption of FASB Financial Interpretation No. 46.
 
    Tax Fees consist of professional services rendered by the independent registered public accounting firm for tax compliance, tax return review and tax advice.
 
    All Other Fees for the 2004 fiscal year for services rendered by the independent registered public accounting firm primarily consist of due diligence and analysis work related to the pending acquisition by the Company of the majority of the U.S. packaged gas business of The BOC Group, Inc.

     The Audit Committee considered whether the services provided above are compatible with maintaining the independent auditor’s independence.

Pre-Approval of Audit and Non-Audit Services

     Under the Audit Committee’s audit and non-audit services pre-approval policy, as adopted by the Audit Committee in 2003, the Audit Committee must pre-approve all audit and non-audit services provided by the independent registered public accounting firm. The policy, as described below, sets forth the procedures and conditions for such pre-approval of services to be performed by the independent registered public accounting firm. The policy utilizes both a framework of general pre-approval for certain specified services and specific pre-approval for all other services.

     Prior to engagement of the independent registered public accounting firm for the next year’s audit, the Audit Committee is asked to pre-approve the engagement of the accounting firm, and the projected fees for audit services and audit-related services (assurance and related services that are reasonably related to the performance of the auditor’s review of the financial statements). The fee amounts approved for the audit and audit-related services are updated to the extent necessary at the regularly scheduled meetings of the Audit Committee during the year.

     In addition, pursuant to its policy, the Audit Committee has pre-approved certain categories of non-audit services to be performed by the independent registered public accounting firm and an aggregate maximum amount of fees to be paid for such services. The Audit Committee receives updates from management and reviews these services at each of its quarterly meetings. Additional pre-approval is required for any of these services if the fees exceed the originally pre-approved aggregate amount annually. If the Company desires to engage the independent registered public accounting firm for other services that are not within the pre-approved categories, the Audit Committee must approve such specific engagement as well as the projected fees.

     In the 2004 fiscal year, there were no fees paid to KPMG LLP under a de minimis exception to the rules that waives pre-approval for certain non-audit services.

     The Board of Directors recommends that you vote FOR ratification of KPMG LLP as the Company’s independent registered public accounting firm.

APPENDIX A

DIRECTOR INDEPENDENCE STANDARDS

     No director of Airgas, Inc. (the “Company”) will be considered “independent” unless the board of directors affirmatively determines that the director has no material relationship with the Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company). When making “independence” determinations, the Board broadly considers all relevant facts and circumstances, as well as any other rules, interpretations and considerations of the New York Stock Exchange (“NYSE”), or any rule or regulation of any other regulatory body or self-regulatory body applicable to the Company. The Board has established the following standards, based upon those set forth in the NYSE Listing Standards, to assist it in determining director independence. These standards shall be interpreted in accordance with interpretations of the NYSE Listing Standards.

     A director will not be independent if within the preceding three years:

    the director was employed by the Company;
 
    an immediate family member of the director was employed by the Company as an executive officer;
 
    the director, or an immediate family member of the director, received more than $100,000 per year in direct compensation from the Company (other than director’s fees and pension or other forms of deferred compensation for prior service with the Company);
 
    the director was affiliated with or employed by the Company’s independent auditor;
 
    an immediate family member of the director was affiliated with or employed by the Company’s independent auditor in a professional capacity; or
 
    an executive officer of the Company was on the compensation committee of the board of directors of a company that employed either the director or an immediate family member of the director as an executive officer.

     None of the following relationships shall disqualify any director or nominee from being considered “independent” and such relationships shall be deemed to be immaterial relationships with the Company:

    a director is an executive officer or an employee, or a director’s immediate family member is an executive officer, of another company that makes payments to, or receives payments from, the Company for property or services in an amount which, in any single fiscal year, does not exceed the greater of (a) $1,000,000 or (b) 2% of such other company’s consolidated gross revenues;
 
    a director or a director’s immediate family member is an executive officer of another company in which the Company owns a common stock interest, and the amount of the common stock interest is less than 5% of the total shareholders’ equity of the company for which the director serves as an executive officer; or
 
    a director or a director’s immediate family member serves as an officer, director or trustee of a charitable organization, and the Company’s contributions to the organization in any single fiscal year are less than the greater of (a) $1,000,000 or (b) 2% of that organization’s gross revenues.

(AS AMENDED THROUGH MAY 25, 2004)

     1. Purpose. AIRGAS, INC. (the “Company”) hereby adopts the Airgas, Inc. 1997 Directors’ Stock Option Plan effective May 15, 1997 (the “Plan”) as an additional incentive to non-employee members of the Company’s Board of Directors to commence or continue service and to devote themselves to the Company’s success by providing them with an opportunity to acquire or increase their proprietary interest in the Company through receipt of (a) rights (the “Options”) to purchase the Company’s Common Stock, par value $0.01 per share (the “Common Stock”) or (b) Common Stock subject to conditions of forfeiture (the “Restricted Stock Awards”).

     2. Administration.

         (a) Committee. The Plan shall be administered by the Governance and Compensation Committee designated by the Company’s Board of Directors (the “Committee”) which shall consist of at least two persons, each of whom is a “non-employee director” as defined under Rule 16b-3 under the Securities Exchange Act of 1934 (the “Exchange Act”) (a “Non-Employee Director”).

         (b) Meetings. The Committee shall hold meetings at such times and places as it may determine. Acts approved at a meeting by a majority of the directors who are members of the Committee and present at a meeting at which there is a quorum, or acts approved in writing by the unanimous consent of the directors who are members of the Committee (not counting any director who is an employee for either purpose) shall be the valid acts of the Committee.

         (c) Grants. The Committee shall from time to time at its discretion direct the Company to grant Options or Restricted Stock Awards pursuant to the terms of the Plan. Subject to the express provisions of the Plan, the Committee shall have plenary authority to determine the persons to whom and the times at which Options or Restricted Stock Awards shall be granted, the number of shares of Common Stock to be granted under an Option or Restricted Stock Award and the price and other terms and conditions thereof. In making such determinations the Committee may take into account the nature of the person’s services and responsibilities, the person’s present and potential contribution to the Company’s success and such other factors as it may deem relevant. The Committee’s interpretation of any provision of the Plan or of any Option or Restricted Stock Award granted under it shall be final, binding and conclusive.

         (d) Exculpation. Each Committee member shall be acting in the capacity of a director of the Company for the purpose of Article VI of the Company’s Certificate of Incorporation in connection with the administration of the Plan or the granting of Options or Restricted Stock Awards under the Plan.

any action, suit or proceeding with respect to the administration of the Plan or the granting of Options or Restricted Stock Awards under the Plan in which he may be involved by reason of his being or having been a Committee member, whether or not he continues to be a Committee member at the time of the action, suit or proceeding.

     3. Eligibility. Each member of the Company’s Board of Directors who is not an employee of the Company or an entity of which the Company owns, directly or indirectly, at least 50% of the value or voting rights of the outstanding equity securities shall be eligible to participate (the “Participants”). The Committee, in its sole discretion, shall determine whether an individual qualifies as a Participant. A Participant may receive more than one Option or Restricted Stock Award, but only on the terms and subject to the restrictions of the Plan.

     4. Available Shares. The aggregate maximum number of shares of the Common Stock for which the Committee may issue Options or Restricted Stock Awards under the Plan is 800,000 shares, adjusted as provided in Section 9 (the “Plan Shares” or “Shares”); provided, however, the Committee may not issue more than 100,000 Shares as Restricted Stock Awards in the aggregate, and Restricted Stock Awards under this Plan and the Company’s 1997 Stock Option Plan in any calendar year may not exceed 0.5% of the shares of Common Stock issued and outstanding on any date of grant. Plan Shares shall be issued from authorized and unissued Common Stock or Common Stock held in or hereafter acquired for the Company’s treasury. If any outstanding Option or Restricted Stock Award granted under the Plan expires, lapses or is terminated for any reason, the Plan Shares allocable to the unexercised portion of such Option or forfeited portion of such Restricted Stock Award may again be the subject of grant pursuant to the Plan.

     5. Term of Plan. The Plan is effective as of May 15, 1997, the date on which it was adopted by the Company’s Board of Directors. No Option or Restricted Stock Award granted under the Plan shall be exercisable or nonforfeitable unless the Plan is approved by vote of a majority of the outstanding voting stock of the Company on or before May 15, 1998. No Option or Restricted Stock Award may be granted under the Plan after May 15, 2007.

     6. Terms and Conditions of Options. Options granted pursuant to the Plan shall be evidenced by written documents (the “Option Documents”) in such form or forms as the Committee shall from time to time approve. Option Documents shall comply with and be subject to the terms and conditions set forth below and such other terms and conditions which the Committee shall from time to time specify with respect to a particular Option or Options, provided they are not inconsistent with the terms of the Plan. The applicable terms need not be uniform between or among Options.

         (a) Number of Shares. Each Option Document shall state the number of Shares to which it pertains.

         (b) Option Price. Each Option Document shall state the price at which Shares under Option may be purchased (the “Option Price”), which shall be at least 100% of the Common Stock’s closing price on the New York Stock Exchange (or such other exchange as the Committee selects) on the date the Option is granted.

         (c) Exercisability.

               (i) General Rule. Unless the Committee provides otherwise in an Option Document and contingent upon the Plan’s approval under Section 5, each Option granted under the Plan shall be exercisable in full on the date of grant. No Option shall be exercisable after its term expires pursuant to subsection 6(e) or 6(f).

               (ii) Change in Control. If a Change in Control of the Company (as defined below) occurs, then all Options which both were not exercisable and have not terminated as of the date of such “Change in Control” shall as of such date become immediately exercisable except to the extent the Participant waives such accelerated right to exercise. A “Change in Control” shall be deemed to have taken place upon the date when (A) as a result of a tender offer, stock purchase, other stock acquisition, merger, consolidation, recapitalization, reverse split, sale or transfer of any asset or other transaction any person or group (as such terms are used in and under Section 13(d) of the Exchange Act) other than the Company, any Affiliate, or any employee benefit plan of the Company or an Affiliate, shall become the beneficial owner (as defined in Rule 13-d under the Exchange Act) directly or indirectly of securities of the Company representing more than 20% of the combined voting power of the Company’s then outstanding securities; providing, however, that this provision shall not apply to Peter McCausland (“McCausland”), unless and until McCausland, together with all affiliates and associates, becomes the beneficial owner of 30% or more of the combined voting power of the Company’s then outstanding securities; (B) stockholders approve the consummation of any merger of the Company or any sale or other disposition of all or substantially all of its assets, if the Company’s stockholders immediately before such transaction own, immediately after consummation of such transaction, equity securities (other than options and other rights to acquire equity securities) possessing less than 50% of the voting power of the surviving or acquiring corporation; or (C) a change in the majority of the individuals who constitute the Company’s Board of Directors occurs during any period of two years for any reason without the approval of at least a majority of directors in office at the beginning of such period.

         (d) Medium of Payment. A Participant shall pay for Shares under Option (i) in cash, (ii) by certified check payable to the order of the Company, (iii) in shares of the Common Stock held by the Participant for at least six months as of the exercise date, (iv) by a combination of the foregoing, (v) by delivery to the Company of a properly executed notice of exercise together with irrevocable instructions to a broker to deliver to the Company promptly the amount of the proceeds of the sale of all or a portion of the Shares or of a loan from the broker to the Participant necessary to pay the aggregate exercise price payable for the purchased Shares plus all applicable federal, state and local income and employment taxes required to be withheld by the Company by reason of such exercise or (vi) by such other mode of payment as the Committee may approve. If payment is made in whole or in part in shares of the Common Stock, then the Participant shall deliver to the Company certificates registered in the name of such Participant representing shares of Common Stock owned by such Participant, free of all liens, claims and encumbrances of every kind and having a fair market value on the date of delivery that is not greater than the Option Price of the Shares with respect to which such Option is to be exercised, accompanied by stock powers duly endorsed in blank by the Participant. Notwithstanding the foregoing, the Committee may impose such limitations and prohibitions on the use of shares of the Common Stock to exercise an Option as it deems appropriate.

         (e) Termination of Options. Unless the Committee provides otherwise in an Option Document, an Option shall not be exercisable after the first to occur of the following:

               (i) Term Expiration. Expiration of the term specified in the Option Document, which shall not exceed ten years from the date of grant;

               (ii) Death. Expiration of one year from the date the Participant’s service as a member of the Company’s Board of Directors terminates due to death; or

               (iii) Forfeiture. The date on which forfeiture occurs under subsection 6(f).

         (f) Forfeiture. An Option shall terminate immediately upon a finding by the Committee, after full consideration of the facts presented on behalf of both the Company and the

B-3

Participant, that the Participant has engaged in any sort of disloyalty to the Company, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty in the course of his service or has disclosed trade secrets or confidential information of the Company. In such event, in addition to immediate termination of the Option, the Participant, upon a determination by the Committee, shall automatically forfeit all Shares for which the Company has not yet delivered the share certificates upon the Company’s refund of the Option Price.

         (g) Transfers. Generally, a Participant may not transfer any Option granted under the Plan, except that (i) during his lifetime, a Participant may transfer an Option to a spouse or a lineal ascendant or descendant or a trust for the benefit of such a person or persons or a partnership in which such persons are the only partners, provided the Participant receives no consideration for any such transfer and (ii) at the Participant’s death, a Participant may transfer an Option by will or by the laws of descent and distribution. If a transfer occurs under this subsection, the transferred Option shall remain subject to all Plan provisions. A transferee shall be required to furnish proof satisfactory to the Committee of the transfer to him by gift or by will or laws of descent and distribution.

         (h) Other Provisions. The Option Documents shall contain such other provisions including, without limitation, additional restrictions upon the exercise of the Option or additional limitations upon the term of the Option, as the Committee shall deem advisable.

         (i) Amendment. The Committee shall have the right to amend Option Documents issued to a Participant subject to the Participant’s consent.

   7. Method of Option Exercise.

         (a) Notice. No Option shall be deemed to have been exercised prior to the Company’s receipt of written notice of such exercise and of payment in full of the Option Price for the Shares to be purchased. Each such notice shall specify the number of Shares to be purchased.

         (b) Securities Laws. Each notice of exercise shall (unless the Shares are covered by a then current registration statement under the Securities Act of 1933, as amended (the “Act”)), contain the Participant’s acknowledgment in form and substance satisfactory to the Company that (i) such Option Shares are being purchased for investment and not for distribution or resale (other than a distribution or resale which, in the opinion of counsel satisfactory to the Company, may be made without violating the registration provisions of the Act), (ii) the Participant has been advised and understands that (A) the Option Shares may not be registered under the Act and may be “restricted securities” within the meaning of Rule 144 under the Act and may be subject to restrictions on transfer and (B) the Company is under no obligation to register the Option Shares under the Act or to take any action which would make available to the Participant any exemption from such registration, and (iii) such Option Shares may not be transferred without compliance with all applicable federal and state securities laws. Notwithstanding the foregoing, should the Company be advised by counsel that issuance of Shares should be delayed pending (iv) registration under federal or state securities laws or (v) the receipt of an opinion that an appropriate exemption therefrom is available, the Company may defer exercise of any Option granted hereunder until either such event in (iv) or (v) has occurred.

         (c) Brokerage Account. Each notice of exercise may instruct the Company, in such form as the Committee shall prescribe, to deliver Shares upon Option exercise to any registered broker or dealer which the Company approves in lieu of delivery to the Participant.

Table of Contents

   8. Terms and Conditions of Restricted Stock Awards. Restricted Stock Awards made pursuant to the Plan shall be evidenced by written documents (the “Award Documents”) in such form or forms as the Committee shall from time to time approve.

         (a) Number of Shares. Subject to Section 4, each Award Document shall state the number of Shares to which it pertains.

         (b) Restrictions and Limitations. Each grant shall be subject to such restrictions as the Committee may impose. The applicable restrictions may lapse separately or in combination at such time or times, or in such installments, as the Committee may deem appropriate. In addition, the Committee may impose limits on the Participant’s right to vote Shares or receive dividends or distributions on Shares under a Restricted Stock Award until such Shares become nonforfeitable. Each Award Document shall provide that the Participant shall forfeit all forfeitable Shares upon a finding by the Committee that the Participant has engaged in conduct that violates subsection 6(f) and that all forfeitable Shares shall become nonforfeitable upon the occurrence of a Change in Control (as defined in subsection 6(c)(ii)).

         (c) Legend. Any certificate issued in respect of a Restricted Stock Award shall be registered in the Participant’s name and shall bear an appropriate legend referring to the terms, conditions and restrictions applicable under the Plan and Award Document to the covered Shares. In addition, until such time as all restrictions applicable to the Shares lapse, the Committee may provide for the certificate to be held in escrow by an escrow agent which the Committee selects and the Company compensates.

         (d) Forfeiture.

               (i) General Rule. If a Participant terminates service during any restriction period under circumstances which result in a forfeiture of Shares covered by the Restricted Stock Award or any event occurs or fails to occur which results in a forfeiture, the restricted Shares shall revert to the Company. Notwithstanding the foregoing, the Committee may waive any restriction applicable to any Restricted Stock Award whenever the Committee determines that such waiver is in the Company’s best interests.

               (ii) Forfeiture for Cause. A Participant shall forfeit all forfeitable Shares covered by a Restricted Stock Award immediately upon a finding by the Committee, after full consideration of the facts presented on behalf of both the Company and the Participant, that the Participant has engaged in any sort of disloyalty to the Company or an Affiliate, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty in the course of his employment or service or has disclosed trade secrets or confidential information of the Company or an Affiliate or engaged in competition with the Company or an Affiliate.

         (e) Transfers. Generally, a Participant may not transfer, assign, alienate, sell, encumber, or pledge Shares under a Restricted Stock Award until they are nonforfeitable and any purported transfer, assignment, alienation, sale, encumbrance or pledge shall be void and unenforceable. Notwithstanding the foregoing, (i) a Participant may transfer forfeitable Shares under a Restricted Stock Award to a spouse or a lineal ascendant or descendant or a trust for the benefit of such a person or persons or a partnership in which such persons are the only partners, provided the Participant receives no consideration for any such transfer and (ii) at the Participant’s death, a Participant may transfer forfeitable Shares under a Restricted Stock Award by will or by the laws of descent and distribution. If a permitted transfer occurs under this subsection, the transferred Shares shall remain subject to all Plan provisions and all applicable conditions and restrictions under the Award Document. A transferee shall be required to furnish proof satisfactory to the Committee of the transfer to him by gift or by will or laws of descent and distribution.

B-5


Table of Contents

         (f) Securities Laws. Upon the advice of counsel, the Committee may require a Participant to take or defer any action with respect to Shares covered under a Restricted Stock Award which counsel determines is necessary to comply with federal or state securities laws.

   9. Adjustments on Changes in Common Stock. The aggregate number of shares and class of shares as to which Options or Restricted Stock Awards may be granted hereunder, the number of Shares covered by each outstanding Option and the Option Price thereof and each Restricted Stock Award shall be appropriately adjusted in the event of a stock dividend, stock split, recapitalization or other change in the number or class of issued and outstanding equity securities of the Company resulting from a subdivision or consolidation of the Common Stock and/or other outstanding equity security or a recapitalization or other capital adjustment (not including the issuance of Common Stock upon the conversion of other securities of the Company that are convertible into Common Stock) affecting the Common Stock which is effected without receipt of consideration by the Company. The Committee shall have authority to determine the adjustments to be made under this Section and any such determination by the Committee shall be final, binding and conclusive.

   10. Amendment of the Plan. The Board of Directors of the Company may amend the Plan from time to time in such manner as it may deem advisable or terminate the Plan in full. Nevertheless, the Board of Directors of the Company may not, without obtaining approval by vote of a majority of the outstanding voting stock of the Company within twelve months after such action, increase the maximum number of shares of Common Stock as to which Options or Restricted Stock Awards may be granted, except as provided in Section 9 hereof.

   11. Continued Service. The grant of an Option or a Restricted Stock Award pursuant to the Plan shall not be construed to imply or to constitute evidence of any agreement, express or implied, on the part of the Company to retain the Participant as a member of the Company’s Board of Directors or in any other capacity.

   12. Withholding of Taxes.

         (a) General Rule. As a condition for the receipt of an Option or Restricted Stock Award, the Participant agrees that the Company (or the Affiliate employing him) may deduct from fees or other amounts payable to him or that he will pay over to the Company any amount necessary to satisfy any federal, state and/or local withholding tax requirements and that the Company shall have the right to take whatever action it deems necessary to protect its interests with respect to tax liabilities resulting from any act or event in connection with the Plan.

         (b) Payment in Shares. The Participant may elect that the Company satisfy any applicable minimum federal, state and/or local withholding tax requirement by retaining Shares the Company would otherwise transfer to him upon his exercise of an Option or satisfaction of all vesting conditions under a Restricted Stock Award which have a fair market value equal to such withholding requirement. Notwithstanding the foregoing, the Committee may impose such limitations and prohibitions on the use of shares of the Common Stock to satisfy withholding tax requirements as it deems appropriate.

   13. Rules of Interpretation. Regardless of the number and gender specifically used, words used in the Plan shall be deemed and construed to include any other number (singular or plural) and any other gender (masculine, feminine or neuter) as the context indicates is appropriate. Section headings are for convenience only; they form no part of the Plan.
