PROXY STATEMENT

ANNUAL MEETING INFORMATION

General

      This Proxy Statement has been prepared in connection with the solicitation by the Board of Directors of Harsco Corporation, a Delaware corporation (the “Company”), of Proxies in the accompanying form to be used at the Annual Meeting of Stockholders of the Company, to be held April 26, 2005, or at any adjournment or adjournments of the Annual Meeting.

      The following information relates to the Annual Meeting and the voting of your shares at the meeting:

Voting

      All shares of common stock entitled to vote at the Annual Meeting are of one class, with equal voting rights. Each share of common stock held by a stockholder is entitled to cast one vote on each matter voted on at the Annual Meeting. In order for the Annual Meeting to be valid and the actions taken binding, a quorum of stockholders must be present at the meeting, either in person or by proxy. A quorum is a majority of the issued and outstanding shares of common stock as of the Record Date. The affirmative vote of the holders of at least 80% of the outstanding shares of common stock of the Company entitled to vote will be required with respect to the proposed amendments to the Restated Certificate of Incorporation and By-Laws to eliminate the classification of the Board of Directors. Assuming that a quorum is present, the affirmative vote by the holders of a plurality of the votes cast at the Annual Meeting will be required to act on the election of directors and the affirmative vote of the holders of at least a majority of the outstanding common stock present in person or by proxy at the Annual Meeting will be required for the ratification of PricewaterhouseCoopers LLP as independent accountants for the current fiscal year. The vote required to act on all other matters to come before the

Annual Meeting will be in accordance with the voting requirements established by the Company’s Restated Certificate of Incorporation and By-Laws.

      The shares of common stock represented by each properly submitted proxy received by the Board of Directors will be voted as follows at the Annual Meeting:

      If instructions are provided, in accordance with such instructions specified, or

      If no instructions are provided, those shares of common stock will be voted (1) FOR the amendments to the Restated Certificate of Incorporation and the By-Laws to eliminate the classification of the Board of Directors; (2) FOR the election of eleven nominees for Directors; (3) solely in the event the stockholders do not approve the amendments to the Restated Certificate of Incorporation and the By-Laws to eliminate the classification of the Board of Directors, FOR the election of four nominees to serve as Directors until the 2008 Annual Meeting; (4) FOR the ratification of the appointment of PricewaterhouseCoopers LLP as independent accountants for the current fiscal year; and (5) in accordance with the best judgment of the named proxies on any other matters properly brought before the Annual Meeting.

Revocation of Proxies

      Any proxy granted pursuant to this solicitation or otherwise, unless coupled with an interest, may be revoked by the person granting the proxy at any time before it is voted at the Annual Meeting. Proxies may be revoked by (i) delivering to the Secretary of the Company a written notice of revocation bearing a later date than the proxy, (ii) duly executing and delivering a later dated written proxy relating to the same shares, or (iii) attending the Annual Meeting and voting in person. If you hold your shares through a bank, broker or other nominee holder, only they can revoke your proxy on your behalf.

Abstentions and Broker Non-Votes

      In certain circumstances, a stockholder will be considered to be present at the Annual Meeting for quorum purposes but will not be deemed to have cast a vote on a matter. That occurs when a stockholder is present but specifically abstains from voting on a matter or when shares are represented at the Annual Meeting by a proxy conferring authority to vote only on certain matters (“broker non-votes”). In accordance with Delaware law, abstentions and broker non-votes will not be treated as votes cast with respect to election of directors, and therefore will not affect the outcome of director elections. With respect to Proposal 1, abstentions and broker non-votes will be treated as negative votes and with respect to each other matter presented at the Annual Meeting, abstentions will be treated as negative votes on such matters, while broker non-votes will not be counted in determining the outcome.

Other Business

      The Board of Directors knows of no other business to come before the Annual Meeting. However, if any other matters are properly presented at the Annual Meeting, or any adjournment of the Annual Meeting, the persons voting the proxies will vote them in accordance with their best judgment.

CORPORATE GOVERNANCE

      The Company has a long-standing commitment to good corporate governance practices. These practices come in many different forms and apply at all levels of the organization. They provide the Board of Directors and senior management of the Company with a framework that defines responsibilities, sets high standards of professional and personal conduct and promotes compliance with the various financial, ethical, legal and other obligations and responsibilities applicable to the Company. During 2004, the Board of Directors took numerous actions to strengthen the Company’s corporate governance practices, including improving its Director mentoring program, strengthening its new Director orientation program, replacing the use of stock options with restricted stock units, adding of a “financial expert” to the Audit Committee and recommending to stockholders the elimination of the classification of the Board of Directors.

      The Company’s corporate governance principles can be viewed at the Governance section of the Company’s website, www.harsco.com. Information contained on the Company’s website is not incorporated by reference into this Proxy Statement, and you should not consider information contained on the Company’s website as part of this Proxy Statement. Copies of the Company’s corporate governance principles and charters of the Board’s committees are available in print to any stockholder who requests such copies from the Company.

BOARD INFORMATION

Structure

      Information regarding the structure of the Company’s Board of Directors:

Meeting Attendance and Committees

      The Board of Directors met eight times during the fiscal year ended December 31, 2004. The average attendance by Directors at all Board and committee meetings was 96%. Mr. Butler attended 63% of meetings of the Board and committees on which he served. The independent directors held two meetings during 2004.

Directors’ Compensation

      The current fees for Non-Employee Directors effective January 1, 2005 are as follows:

      Directors who are actively employed by the Company receive no additional compensation for serving as Directors and by policy, the Company does not pay consulting or professional service fees to Directors.

Stockholder Communications with the Board of Directors

      The Board of Directors has a formal process for stockholders to communicate directly with its members. Stockholders can contact the Board through the Chairman and Chief Executive Officer who is located at the Company’s headquarters in Camp Hill, Pennsylvania. In addition, stockholders may contact any member of the Board, including the lead independent director, Dr. Robert Wilburn, by writing to the specific Board member in care of the Corporate Secretary at the Corporate Headquarters (350 Poplar Church Road, Camp Hill, PA 17011). The Corporate Secretary will forward any such correspondence to the applicable Board member. In addition, Board members can be contacted by e-mail at BoardofDirectors@Harsco.com.

      It is the Company’s policy to request that all Board members attend the Annual Meeting of Stockholders. However, the Company also recognizes that personal attendance by all Directors is not always possible. All ten then-current Directors attended the 2004 Annual Meeting of Stockholders. Ms. Eddy did not join the Board of Directors until August 1, 2004.

The Nominating Process

      The Nominating and Corporate Governance Committee of the Board of Directors (the “Nominating Committee”) is responsible for overseeing the selection of qualified candidates to serve as members of the Board of Directors and guiding the corporate governance philosophy and practices of the Company. The Nominating Committee is composed of five directors each of whom is “independent” under the rules of the New York Stock Exchange and the Pacific Stock Exchange. The Nominating Committee operates according to a charter that complies with the guidelines established by the New York Stock Exchange and the Pacific Stock Exchange.

      The Nominating Committee has not adopted formal procedures in selecting individuals to serve as members of the Board of Directors. Instead, it utilizes general guidelines that allow it to adjust the process to best satisfy the objectives established for any director search. The first step in the general process is to identify the type of candidate the Nominating Committee may desire for a particular opening. This may involve identifying someone with a specific background, skill set or experiences. Once identified, the Committee next determines the best method of finding a candidate who satisfies the specified criteria. The Nominating Committee may consider candidates recommended by management, by other members of the Committee or the Board of Directors, by stockholders, or it may engage a third party to conduct a search for possible candidates. The Nominating Committee accepts recommendations for director candidates from stockholders if such recommendations are in writing and set forth the following information:

      This information must be submitted as provided under the heading “STOCKHOLDER PROPOSALS AND NOMINATIONS FOR PRESENTATION AT 2006 ANNUAL MEETING OF STOCKHOLDERS.”

      There have been no material changes to the procedures relating to stockholder nominations during 2004, except for the formalization of the foregoing procedural requirements reflected above. The Nominating Committee believes that these formalized procedural requirements are intended solely to ensure that it has a sufficient basis on which to assess potential candidates and are not intended to discourage or interfere with appropriate stockholder nominations. The Nominating Committee does not believe that any such requirements subject any stockholder or stockholder nominee to any unreasonable burden. The Nominating Committee and the Board reserve the right to change the above procedural requirements from time to time and/or waive some or all of the foregoing requirements with respect to certain nominees,

but any such waiver shall not preclude the Nominating Committee from insisting upon compliance with any and all of the above requirements by any other recommending stockholder or proposed nominees.

      Once candidates are identified, the Nominating Committee conducts an evaluation of the candidate. The evaluation generally includes interviews and background and reference checks. There is no difference in the evaluation process of a candidate recommended by a stockholder as compared to the evaluation process of a candidate identified by any of the other means described above. While the Nominating Committee has not established minimum criteria for a candidate, it has established important factors to consider in evaluating a candidate. These factors include: strength of character, mature judgment, business experience, availability, attendance, career specialization, relevant technical skills, diversity and the extent to which the candidate would fill a present need on the Board of Directors.

      If the Nominating Committee determines that a candidate should be nominated as a candidate in the Proxy Statement, the candidate’s nomination is then recommended to the Board of Directors, who may in turn conduct its own review to the extent it deems appropriate. When the Board of Directors has agreed upon a candidate, they are then recommended to the stockholders for election at an Annual Meeting of Stockholders.

      All current directors have been recommended by the Nominating Committee to the Board of Directors for election as directors of the Company at the 2005 Annual Meeting of Stockholders and the Board has approved the recommendation. In the event that the proposal to eliminate the classification of the Board of Directors of the Company is not approved by stockholders, Messrs. Fazzolari, Sordoni, Viviano and Ms. Scanlan, each of whom is a current Director, have been recommended by the Nominating Committee for election as Directors of the Company to serve until the 2008 Annual Meeting, and the Board of Directors has approved the recommendation. The Company did not engage a third party search firm to assist with the selection of the director candidates for the 2005 Annual Meeting of Stockholders. During 2004, the Company received no recommendation for directors from any stockholders.

PROPOSAL 1: APPROVAL OF AMENDMENTS TO THE RESTATED CERTIFICATE OF INCORPORATION AND BY-LAWS OF THE COMPANY TO ELIMINATE THE CLASSIFICATION OF THE BOARD OF DIRECTORS

      The Board of Directors is currently separated into three classes. Each year, the stockholders are requested to elect the directors comprising one of the classes for a three-year term. Currently, the term for four Directors is set to expire in 2005 at this year’s Annual Meeting. The term of four other Directors is set to expire in 2006 and the term of the other three Directors is set to expire in 2007. Because of the classified Board structure, stockholders have the opportunity to vote on approximately one-third of the Directors each year.

      The Board of Directors has approved and is proposing to the stockholders amendments to the Restated Certificate of Incorporation and By-Laws to eliminate the classified board structure. If the stockholders approve this proposal, the terms of all Directors will expire at the annual meeting of stockholders each year and their successors will be elected for one-year terms that will expire at the next annual meeting. The text of the Certificate of Amendment to the Restated Certificate of Incorporation that will be filed with the Secretary of State of the State of Delaware if Proposal 1 is approved as set forth in Appendix A attached to this Proxy Statement. The amended and restated By-Laws, including the proposed amendments, are set forth in Appendix B attached to this Proxy Statement.

      The Board of Directors believes that stockholders should have the opportunity to vote on all Directors each year and that elimination of the classified board structure will be an effective way to maintain and enhance the accountability of the Board of Directors. In making this determination, the Board of Directors has considered that removing the classified Board of Directors will have the effect of reducing the time required for a majority stockholder or group of stockholders to replace a majority of the Board of Directors in any single year. Under a classified Board of Directors, a majority of the Board of Directors may be replaced only after two years. In addition, under Delaware law, directors of a classified Board of Directors may be removed only for cause. This limitation on removal of Directors only for cause would no longer apply if Proposal 1 is approved.

      If the stockholders approve this proposal, each of the eleven Directors who are elected at the annual meeting will be elected for a one-year term that will expire at next year’s annual meeting. The entire Board of Directors will be subject to election at next year’s annual meeting. Approval of the amendments to the Restated Certificate of Incorporation and By-Laws to eliminate the classification of the Board of Directors requires the affirmative vote of at least 80% of the shares of common stock issued and outstanding as of the record date, or approximately             million shares.

      If the stockholders approve this proposal, the amendments to the Restated Certificate of Incorporation will become effective upon the filing of a Certificate of Amendment to the Restated Certificate of Incorporation with the Secretary of the State of Delaware, the text of which is set forth in Appendix A attached to this Proxy Statement. The Company plans to file the amendment immediately after the requisite vote is obtained. The Stockholders will then be asked to vote on Proposal 2 and a vote on Proposal 3 will not be taken at the Annual Meeting.

      If the stockholders approve this Proposal 1, certain administrative changes will be made to the By-Laws. These administrative changes have been approved by the Board of Directors subject to the approval by the stockholders of this Proposal 1 and do not require separate approval by the stockholders. These administrative changes are included in the proposed Amended and Restated By-Laws set forth in Appendix B attached to this Proxy Statement. All of the amendments to the By-Laws will become effective concurrently with the effectiveness of the amendments to the Restated Certificate of Incorporation.

The Board of Directors Recommends that Stockholders Vote “FOR” the Amendments to the Restated Certificate of Amendment and the By-Laws to Eliminate the Classified Board of Directors.

PROPOSAL 2: ELECTION OF DIRECTORS

      The second proposal to be voted on at the Annual Meeting is the election of the following eleven Directors, each of whom is recommended by the Board of Directors. Biographical information about each of these nominees is included below.

      If the Stockholders approve Proposal 1 (elimination of the classified Board of Directors) at the Annual Meeting, each of the nominees who is elected will serve a one-year term and will be subject to reelection at next year’s annual meeting. See Proposal 1 above. If Proposal 1 is not approved, stockholders will not be asked to vote for this proposal, and instead will vote on Proposal 3.

The Board of Directors Recommends that Stockholders Vote ‘FOR’ the Election of Each of the Following Nominees:

DIRECTOR INFORMATION

      The information set forth below states the name of each nominee for Director, his or her age, a listing of present and previous employment positions, the year in which he or she first became a Director of the Company, other directorships held and the committees of the Board on which the individual serves.

PROPOSAL 3: ELECTION OF DIRECTORS (IN THE ALTERNATIVE TO PROPOSAL 2)

      Stockholders will be asked to vote on this Proposal 3 solely in the event that, at the Annual Meeting, the stockholders do not approve the amendments to the Company’s Restated Certificate of Incorporation and By-Laws to eliminate the classification of the Board of Directors as described in Proposal 1. If the stockholders approve Proposal 1, then the Company will amend the Restated Certificate of Incorporation and By-Laws to eliminate the classification of the Board of Directors, and the stockholders will proceed to vote on Proposal 2 and not this Proposal 3. If, however, the stockholders do not approve Proposal 1, a vote will be taken on this Proposal 3.

      If the stockholders do not approve Proposal 1, each of the following are nominated for election to serve a three-year term and will be subject to re-election at the 2008 Annual Meeting: Salvatore D. Fazzolari, Carolyn F. Scanlan, Andrew J. Sordoni, III, and Joseph P. Viviano. See above for information regarding each such Director nominee, including his or her age, a listing of present and previous employment positions, the year in which he or she first became a Director of the Company, other directorships held and the committees of the Board on which the individual serves.

      If the stockholders do not approve Proposal 1, Directors whose terms expire at the 2006 Annual Meeting are Messrs. Hathaway, Jasinowski, Pierce and Ms. Eddy and Directors whose terms expire at the 2007 Annual Meeting are Messrs. Butler, Scheiner and Wilburn.

The Board of Directors Recommends that the Stockholders Vote ‘FOR’ Salvatore D. Fazzolari, Caroloyn F. Scanlan, Andrew J. Sordoni, III and Joseph P. Viviano.

NON-DIRECTOR EXECUTIVE OFFICERS

SHARE OWNERSHIP OF DIRECTORS, MANAGEMENT AND CERTAIN BENEFICIAL OWNERS

      The following table sets forth, as of January 31, 2005, information with respect to the beneficial ownership of the Company’s outstanding voting securities, stock options and other stock equivalents by:

      All of the Company’s outstanding voting securities are common stock.

      Except as otherwise stated, each individual has sole voting and investment power over the shares set forth opposite his or her name. As of January 31, 2005, Mr. Hathaway beneficially owned 1.2% of the Company’s common stock. None of the other Directors and executive officers individually beneficially owned more than 1% of the Company’s common stock, and the Directors and executive officers of the Company as a group beneficially owned approximately 2.24% of the Company’s outstanding common stock. The mailing address for the Directors and executive officers of the Company is c/o Harsco Corporation Corporate Secretary, 350 Poplar Church Road, Camp Hill, PA 17011.

REPORT OF THE AUDIT COMMITTEE

      The Audit Committee of the Board of Directors (the “Audit Committee”) is composed of five Directors each of whom is considered independent under the rules of the New York Stock Exchange, the Pacific Stock Exchange and the Securities and Exchange Commission (“SEC”). During 2004, the Audit Committee added to its membership an individual who satisfies the definition of a “financial expert,” as promulgated by the SEC. Ms. Kathy Eddy, a certified public accountant and former Chairman of the American Institute of Certified Public Accountants, became a member of the Harsco Board of Directors on August  1, 2004 and became a member of the Audit Committee on September 28, 2004.

      The Audit Committee operates pursuant to a written charter which was adopted in 1992 and which was most recently amended in February of 2004. A copy of the Audit Committee Charter can be reviewed at the Governance section of the Company’s website.

      The Audit Committee has adopted a policy for pre-approval of audit, non-audit and tax services by the independent auditors. The Audit Committee may pre-approve services, such as the annual audit fee and statutory audits. The services to be provided are to be reviewed with the Audit Committee and approval is given for a specific dollar amount and for a period of not greater than 12 months. Services that are not pre-approved in this manner must be pre-approved on a case-by-case basis throughout the year. Additionally, if the pre-approved fee is to be exceeded, approval of the Audit Committee must be obtained. In making its decision regarding the approval of services, the Audit Committee will consider whether such services are consistent with the SEC’s rules on auditor independence, whether the independent auditor is best positioned to provide such services and whether the services might enhance the Company’s ability to manage or control risk or improve audit quality. No services were provided during the last two fiscal years pursuant to the de minimis safe harbor exception from the pre-approval requirements.

      The Audit Committee reports to and acts on behalf of the Board of Directors by monitoring the Company’s financial reporting processes and system of internal controls, and overseeing the Company’s internal auditors and the independence and performance of the independent accountants. In carrying out these responsibilities, the Audit Committee meets with members of management, the Company’s independent auditors and the Company’s internal auditors on a regular basis or as may otherwise be needed. The Audit Committee Chairman or his designee meets with management and with the independent accountants each quarter to review and discuss the Company’s Quarterly Report on Form 10-Q or Form 10-K prior to their filing with the SEC.

      While the Audit Committee and Board of Directors monitor the Company’s financial record keeping and controls, it is the Company’s management that is ultimately responsible for the Company’s financial reporting process, including the Company’s system of internal controls, disclosure control procedures and the preparation of the financial statements. The independent accountants support the financial reporting process by performing an audit of the Company’s financial statements and issuing a report thereon.

      The Audit Committee has reviewed and discussed with management and the independent auditors the audited consolidated financial statements for the year ended December 31, 2004 and related periods. These discussions focused on the quality, not just the acceptability, of the accounting principles used by the Company, key accounting policies followed in the preparation of the financial statements and the reasonableness of significant judgments made by management in the preparation of the financial statements and alternatives that may be available.

      The Audit Committee also discussed with the Company’s internal auditors and independent auditors the overall scope and plans for their respective audits of the Company’s financial statements. In addition, the Audit Committee discussed with the independent accountants the matters required to be discussed by Statement on Auditing Standards No. 61 (Communications with Audit Committees), including the quality of the Company’s accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements. The Audit Committee also discussed with PricewaterhouseCoopers, LLP, the Company’s independent accountants, matters relating to its independence, including a review of audit and non-audit fees and the written disclosures and letter received by the Company from its independent auditors required to be delivered by Independence Standards Board Standard No. 1 (Independence Discussion with Audit Committees).

      Based on the review and discussions referred to above, the Audit Committee’s review of the representations of management and the report of the independent accountants, the Audit Committee recommended to the Board of Directors that the Company’s audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2004 for filing with the SEC.

SUBMITTED BY THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS:

FEES BILLED BY THE ACCOUNTANTS FOR AUDIT AND NON-AUDIT SERVICES

      The following table sets forth the amount of audit fees, audit-related fees, tax fees and all other fees billed or expected to be billed by PricewaterhouseCoopers LLP, the Company’s principal accountant for the year ended December 31, 2004 and December 31, 2003.

      The Audit Committee has considered the possible effect of non-audit services on the accountants’ independence and approved the type of non-audit services to be rendered.

PROPOSAL 4: APPOINTMENT OF INDEPENDENT ACCOUNTANTS

      The Audit Committee has designated PricewaterhouseCoopers LLP as independent accountants to audit the Company’s financial statements for the fiscal year ending December 31, 2005. This firm has audited the financial statements of the Company and its predecessors since 1929. Although not required to do so by law or otherwise, the Audit Committee desires that stockholders ratify its selection of PricewaterhouseCoopers LLP as the Company’s independent accountants. Therefore, the Audit Committee’s choice of independent accountants will be submitted for ratification or rejection at the Annual Meeting. In the absence of contrary direction from stockholders, all proxies that are submitted will be voted in favor of the confirmation of PricewaterhouseCoopers LLP as the Company’s independent accountants. A representative of PricewaterhouseCoopers LLP will attend the Annual Meeting, with the opportunity to make a statement and answer questions of stockholders.

      If this proposal is not ratified by a majority of the shares entitled to vote at the Annual Meeting, the appointment of the independent accountants will be reevaluated by the Audit Committee. Due to the difficulty and expense of making any substitution of accountants, it is unlikely that their appointment for the audit of the financial statements for the fiscal year ending December 31, 2005 would be changed. However, the Audit Committee may review whether to seek new independent accountants for the fiscal year ending December 31, 2006.

      The Audit Committee, at its meeting held on November 16, 2004, reviewed and approved the fee estimate for the annual audit of the Company’s fiscal 2004 financial statements and, taking into consideration the possible effect of non-audit services on the accountants’ independence, also reviewed specific non-audit services to be rendered for income tax services.

      The Board of Directors Recommends a Vote FOR the Ratification of the Appointment of PricewaterhouseCoopers LLP as the Company’s Independent Accountants.

HARSCO STOCK PERFORMANCE GRAPH

      The following performance graph compares the yearly percentage change in the cumulative total stockholder return (assuming the reinvestment of dividends) on the Company’s common stock against the cumulative total return of the Standard & Poor’s MidCap 400 Index and the Dow Jones Industrial-Diversified Index for the past five years. The graph assumes an initial investment of $100 on December 31, 1999 in the Company’s common stock or in the underlying securities which comprise each of those market indices. The information contained in the graph is not necessarily indicative of future Company performance.

MANAGEMENT DEVELOPMENT AND COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

      The Company’s executive compensation program is administered by the Management Development and Compensation Committee (“Compensation Committee”) of the Board of Directors. The Compensation Committee is currently composed of the five non-employee Directors listed below this Report. Each member of the Compensation Committee is considered to be independent in accordance with the guidelines established by the New York Stock Exchange and the Pacific Stock Exchange and no member has any interlocking or other relationships with the Company that are subject to disclosure under the Securities and Exchange Commission rules relating to proxy statements. All decisions of the Compensation Committee relating to the salaries and grade levels of the Company’s executive officers are reviewed by the full Board.

      The Compensation Committee believes that the Company benefits from a broad based executive compensation program with approximately 30 division officers, five executive officers and one other corporate officer participating in the program as of December 31, 2004.

Program Goals

      In administering the Company’s executive compensation program, the Compensation Committee looks to accomplish the following goals:

Other Key Guiding Principles

      In addition to the above goals, the Compensation Committee administers the Company’s executive compensation programs with these guiding principles in mind:

Program Components

      The Compensation Committee carries out the executive compensation program through various compensation methods and programs. The primary compensation methods used and the manner in which they are administered include the following:

      In establishing the weight of these various compensation components, the Compensation Committee believes that as an executive’s level of responsibility increases, a greater portion of his or her potential total compensation opportunity should be based on performance incentives and a lesser portion on salary. The Compensation Committee also believes that as executives rise to positions that can have a greater impact on the Company’s performance, the compensation program should place more emphasis on the value of the common stock.

Salaries

      The Compensation Committee completed its annual review of officer salaries at the December 15, 2003 Committee meeting. In establishing 2004 salaries, the Compensation Committee considered a comprehensive compensation survey review that the Company’s compensation consultant, Towers Perrin, had prepared at the Compensation Committee’s request.

      Each year, the Compensation Committee considers adjustments to the salary of each executive officer based upon a combination of the following: the available salary budget, the

performance of each officer, comparison survey data provided by one or more major consulting firms, comparison to other internal salaries and the Company’s salary range structure for various grade levels. The salary range structure for various grade levels is also revised from time to time based upon industry survey data provided by Towers Perrin. The Towers Perrin industry compensation survey considered by the Compensation Committee is a broad based survey of companies selected by the consulting firm which are not limited to the companies within the Dow Jones Industrial-Diversified Index referenced elsewhere in the Proxy Statement, though some of those companies may have been included in the survey.

Annual Incentive Compensation Plan

      Payments for executive officers under the 1995 Incentive Plan for calendar year 2004 were dependent upon achievement of EVA targets for the business units in the case of Mr. Butler, and the achievement of an EVA objective for the Company, in the case of the other executive officers. These EVA objectives were established by the Compensation Committee prior to the beginning of the year.

      Payments under this Plan are a function of the executive’s annual salary multiplied by the bonus percentage, which in turn is multiplied by a performance percentage. The bonus percentage is determined for each individual executive and is a function of the individual’s level of responsibilities and his or her ability to impact the overall results of the Company. The percentage is calculated by multiplying the individual’s salary grade by .02. The target bonus percentage for Mr. Hathaway is 70% and the target bonus percentages for the other executive officers range from 38% to 54%.

      The performance percentage is determined based on achievement of EVA objectives and can range from 0 to 200%. The EVA objectives include various performance levels. The 2004 EVA objectives, which were developed with input from Stern Stewart & Company, include minimum, target and maximum performance levels. Performance which is below the minimum performance level results in a zero performance percentage and therefore, no incentive payments being made. The performance percentage increases above zero once the minimum performance level is obtained and increases as results increase above the minimum level. For 2004, the performance percentage for achieving the target level of EVA performance results is 100%. If the maximum performance level is obtained or surpassed, the performance percentage is capped at 200%.

      The Compensation Committee, again with the input of Stern Stewart & Company, has established minimum, target and maximum objectives for overall Company EVA performance for 2005 and has allocated that target objective among the divisions. Thus, the annual incentive compensation awards of the corporate officers are closely related to the overall performance of the divisions against their EVA goals.

      Based on his business unit’s achievements against the established EVA targets, Mr. Butler attained 151% of target achievement. The other four named executive officers attained 148% of target achievement for the 2004 based on the overall EVA achievement of the Company. The amounts of the awards to the named executive officers under the Plan are summarized in the Summary Compensation Table.

Long-term Compensation

      Stock options have been the vehicle through which the long-term incentive compensation was granted to employees. No stock options were issued by the Company during 2004. During

2003, the Compensation Committee, on the recommendation of management, decided to take a one-year leave in the issuance of options to study the impact options issuance were having on the Company, stockholders and employees. In December of 2003, the Compensation Committee again decided not to issue options in 2004, but instead asked management to develop a long-term equity compensation program for key senior managers in the Company. As noted above, the Compensation Committee did approve a long-term restricted stock unit program during 2004.

      Under the restricted stock unit program, performance goals will be established three years in advance by the Compensation Committee. 2004, 2005 and 2006 earnings per share goals were established by the Compensation Committee in early 2004. The Compensation Committee approved the 2007 goals of earnings per share and cash flow at its January 2005 meeting. Grants of restricted stock units are made in the subsequent January if the performance goals are achieved. Maximum restricted stock units grants, ranging from 10,000 shares annually for the CEO to 500 for certain other officers, may be granted by the Compensation Committee provided the performance goals are satisfied. The Compensation Committee has complete discretion on whether to grant and the amount (i.e., discretion to reduce the maximum grant by any amount, even to zero) of any grant of restricted stock units that may be made annually to any officer. If shares are granted, they must be held by the individual for a period of three years. If the individual leaves the employment of the Company during this period, except as a result of death, disability or retirement, the stock units are forfeited. 2004 performance goals were achieved and the Compensation Committee did make grants of restricted stock units to Messrs. Butler, Fazzolari, Kimmel and Schnoor as well as certain other officers of the Company. As was described in a Form 8-K filing made by the Company on January 27, 2005, the Compensation Committee and the Board approved a payment to Mr. Hathaway, in lieu of a restricted stock unit award. Mr. Hathaway’s current stock holdings and outstanding stock options and the state of his career at Harsco were considered in making this determination. Mr. Hathaway’s cash payment was equal to $504,050 and was based on the average of the high and low sales price of the Company’s common stock on January 24, 2005 and 10,000 shares.

      The 1995 Incentive Plan was approved by the stockholders in 1995, was amended and reapproved by the stockholders in 1998, 2001 and 2004, and has been used to make grants of options to other corporate officers and key employees, including division officers as well as the executive officers. No stock options were granted in 2004. The guidelines for the maximum annual number of options granted for each grade level were established in January 2001 based upon a recommendation from Towers Perrin, and that firm’s year 2000 survey of the long-term incentive compensation and total compensation practices of major U.S. companies. Towers Perrin used a Black-Scholes valuation of the Company’s options to make comparisons of compensation value. The number of options granted to a particular officer was determined by grade level and the Compensation Committee’s evaluation of the strategic performance of the individual and the individual’s business unit. The absolute maximum stock option award as provided in the 1995 Incentive Plan is 150,000 shares for any single participant in a calendar year. The 1995 Incentive Plan was further amended in 2004 in order that the 150,000 share limit will also apply to awards of restricted stock, deferred stock and stock grants which may be issued under the 1995 Incentive Plan.

Other Compensation

      The Company has certain other broad-based employee benefit plans in which the executive officers participate on the same terms as non-executive employees, including health

insurance, a defined benefit pension plan, a 401(k) Savings Plan and the term life insurance benefit equal to two times the individual’s salary up to a maximum benefit of $500,000. In addition, the executive officers participate in the Supplemental Retirement Benefit Plan as described elsewhere in this Proxy Statement, which supplements both the qualified pension plan and the Company’s 401(k) Savings Plan. During 2003, the Company amended most of its defined-benefit pension plans to end further accruals under the plan for additional service with the Company. After 2003, benefits paid under these amended plans take into account future salary increases of participants. Certain named executive officers, namely Messrs. Hathaway, Butler and Fazzolari, are entitled to Company-provided cars and the Board of Directors has approved Mr. Hathaway’s personal use of the Company airplane.

The Chief Executive Officer’s 2004 Compensation

      The 1995 Incentive Plan cash and salary awarded or paid to Mr. Hathaway with respect to 2004 are discussed in the Summary Compensation Table on page 27 in this Proxy Statement with respect to amounts, and in this Report with respect to the factors considered by the Compensation Committee. Mr. Hathaway’s 2004 salary was determined by the Compensation Committee utilizing the same factors as are explained in the “Salaries” section above. The Compensation Committee particularly considered the significant accomplishments achieved by the Company in 2003, including increases in sales, earnings and cash flows. As was stated above, Mr. Hathaway’s annual incentive payment was primarily a function of the Company’s overall EVA performance. As described above, Mr. Hathaway was also paid a cash amount in lieu of his restricted stock unit grant. This payment was based on the achievement of pre-established EPS goals by the Company. Of the total $2,336,450 in cash compensation paid to Mr. Hathaway for 2004 as reflected in the Summary Compensation Table, 61.5% was contingent and dependent upon the achievement of the EVA and EPS performance objectives established by the Compensation Committee. This is consistent with the Compensation Committee’s view that those executives most able to affect the performance of the Company should have a significant portion of their potential total compensation at risk and dependent upon the Company’s performance.

Relationship of Performance to Compensation

      The Company currently ties executive pay to corporate performance primarily through the 1995 Incentive Plan annual awards that are based upon achievement of objectives adopted by the Compensation Committee. Stock option and restricted stock grants have been made in the past to executives and they only provide realizable compensation through increases in the stock price.

Policy Regarding IRC Section 162

      Section 162(m) of the Internal Revenue Code limits the deductibility of executive compensation for individuals in excess of $1 million per year paid by publicly traded corporations to the chief executive officer and the four other executives named in the compensation table of the Proxy Statement. The Company has determined that given the rates of compensation currently in effect and the exemption under Internal Revenue Service regulations applicable to income derived from stock options granted under the Harsco 1986 Stock Option Plan or the 1995 Incentive Plan, and the exemption applicable to the performance based incentive compensation bonuses under the 1995 Incentive Plan, the Company should not be exposed to any non-deductibility of executive compensation expense under Section 162(m) in the 2004

tax year. In 1995, the Company obtained stockholder approval of the 1995 Incentive Plan, which was designed to preserve the deductibility to the extent possible, of executive compensation resulting from performance based awards under that Plan. The Company obtained renewal of that approval by the stockholders in 1998, 2001 and again in 2004. While the tax deductibility of compensation paid is a key concern for the Compensation Committee, it is not the only concern, and the Compensation Committee will look at other factors to determine the appropriate compensation that should be paid to an individual and may chose to pay compensation that would otherwise not be deductible under Section 162(m) if the Compensation Committee believes that it is appropriate and in the best interest of the Company.

Summary

      In summary, the Compensation Committee believes that the Company’s total compensation program achieves the objective of providing meaningful and appropriate rewards, recognizing both current contributions to performance and the attainment of long-term strategic business goals of critical importance to the future growth of Harsco Corporation.

EXECUTIVE COMPENSATION AND OTHER INFORMATION

Summary of Cash and Certain Other Compensation

      The following table sets forth information concerning the compensation awarded to, earned by or paid to the Named Executives for services rendered to the Company in all capacities during each of the last three fiscal years.

Summary Compensation Table

Stock Options Issued During the 2004 Fiscal Year

      The Board of Directors, on the recommendation of Senior Management, decided not to issue any stock options during 2004 to Company management or employees. It was the Board’s intention to review, during 2003, the appropriateness of the use of stock options as the vehicle for long-term compensation within the Company. In December 2003, the Board decided again not to issue any stock options in 2004 to Company management or employees. Instead, the Board has decided that restricted stock or restricted stock units should be the long-term compensation method for the Company. At the 2004 Annual Meeting, the stockholders approved an amendment to the Company’s 1995 Executive Incentive Compensation Plan which could qualify future grants of restricted stock or restricted stock units as performance-based compensation under Section 162(m) of the Internal Revenue Code. Restricted stock units were awarded to four executive officers and certain other officers of the Company in January 2005 as further discussed in the Compensation Committee Report. The Company does not currently intend to grant any stock options in 2005.

Option Exercises and Holdings

      The following table sets forth information, with respect to the Named Executives, concerning the exercise of options during fiscal year 2004 and unexercised options at December 31, 2004:

AGGREGATED OPTION EXERCISES IN 2004

Retirement Plans

      The Company provides retirement benefits for each officer under the Supplemental Retirement Benefit Plan (“Supplemental Plan”). All executive officers are covered by the Supplemental Plan excepting Mr. Butler who is covered by the U.K. pension plan described below. Until December 31, 2002, the Supplemental Plan replaced the 401(k) Company match lost due to government limitations on such contributions. The replacement was in the form of phantom shares as more fully described in footnote 2 on page 27. The Supplemental Plan was amended effective January 1, 2003, to eliminate any future replacement of lost company match and any further granting of phantom shares. A new non-qualified restoration plan was established January 1, 2004 to provide for the discretionary and matching contribution that would be otherwise provided under the qualified 401(k) Plan for salaried employees’ contributions made after December 31, 2003, but for IRS Code limitations under Section 402(g), Section 401(a)(17), Section 415 or Section 401(m). (See footnote 2 on page 27) All U.S. executive officers are also covered by the qualified pension plan. Each plan is a defined benefit plan providing for normal retirement at age 65. Early retirement may be taken commencing with the first day of any month following the attainment of age 55, provided at least 15 years of service have been completed. Early retirement benefits commencing prior to age 65 are reduced. The Supplemental Plan also provides for unreduced pension benefits if retirement occurs after age 62, provided at least 30 years of service have been completed. The Supplemental Plan provides for a pre-retirement death benefit payable in a monthly benefit to a beneficiary designated by the participant for participants who die after qualifying for benefits. The Supplemental Plan also includes provisions which fully vest participants upon termination of employment following a “change in control” of the Company as defined in the Supplemental Plan.

      The following table shows estimated total annual pension benefits payable to the U.S. executive officers of the Company under the qualified pension plan and the Supplemental Plan, including the Named Executives upon retirement at age 65, in various remuneration and year-of-service classifications, assuming the total pension benefit was payable as a straight life annuity guaranteed for ten years and retirement took place on January 1, 2004.

PENSION PLAN TABLE — U.S. EXECUTIVES

      Total pension benefits are based on final average compensation and years of service. The normal retirement benefit under the Supplemental Plan is equal to a total of .8% of final average compensation up to the “Social Security Covered Compensation” as defined in the Supplemental Plan plus 1.6% of the final average compensation in excess of the “Social Security Covered Compensation” multiplied by up to 33 years of service, reduced by the benefits under the qualified plan. Final Average Compensation is defined as the aggregate compensation (base salary plus nondiscretionary incentive compensation) for the 60 highest consecutive out of the last 120 months prior to date of retirement or termination of employment prior to normal retirement date. The Supplemental Plan was amended in 2002 to provide that for any retirements on or after January 1, 2003, the 1.6% factor in the benefit formula is reduced to 1.5% and the definition of Final Average Compensation was amended to reduce the amount of nondiscretionary incentive compensation included in the benefit calculation from 100% to 50%, for such amounts paid on or after January 1, 2003. Notwithstanding these amendments, no participant’s retirement benefit shall be reduced by reason of these amendments, below the benefit accrued at December 31, 2002. The Supplemental Plan was amended December 31, 2003 to provide that pension benefit accrual service shall not be granted to any Company employee after December 31, 2003, provided, however, compensation earned for services performed for the Company for current Supplemental Plan participants through December 31, 2013 shall be included in determining their Final Average Compensation under the Supplemental Plan.

      The Company does not provide retiree medical benefits to its executive officers.

PENSION PLAN TABLE — U.K. EXECUTIVE

      The above table shows estimated total annual pension benefits payable to the U.K. executive officer of the Company, Mr. Butler, for life, under the Harsco Pension Scheme (the “Scheme”), a qualified pension plan in the U.K., upon retirement at age 60, which is normal retirement age under the Scheme, in various remuneration and year-of-service classifications, assuming the total pension benefit was payable and retirement took place on January 1, 2005. The benefit would be paid in British pounds and all amounts in the table below are stated in U.S. dollars at a conversion rate of $1.9185 = £1.00. The Scheme provides that if the participant dies within five years after starting to receive a pension, a lump sum will be paid equal to the pension payments that would have been made during the remainder of the five year period. The annual pension benefit is based on the highest annual total of salary and bonus within the last five years (or the highest average amount of annual salary plus bonus received in any three consecutive scheme years within the last ten years, if higher) (“Final Pensionable Salary”) and the years of service, subject to various deductions for service prior to April 6, 1989, and a statutory limitation of two thirds of the Final Pensionable Salary. The Scheme was amended in 2002 to provide that for any retirements on or after January 1, 2003, the benefit accrual rate is reduced, and the definition of Final Pensionable Salary is amended to reduce the amount of incentive bonus included in the calculation from 100% of 50% for such amounts paid on or after January 1, 2003. The Plan was amended in 2003 to provide that, in respect of service after January 1, 2004 only, normal retirement age is increased to 65, and the definition of Final Pensionable Salary is amended so as to be equal to the average salary and 50% of bonus over the last five scheme years prior to retirement.

Employment Agreements with Officers of the Company

      On September 25, 1989, the Board of Directors authorized the Company to enter into employment agreements with certain officers, including Mr. Hathaway, and subsequently with Messrs. Fazzolari and Butler (the “Agreements”). Pursuant to those authorizations, the Company entered into an individual Agreement with each of these individuals. The Agreements are designed as an inducement to retain the services of the officers and provide for continuity of management during the course of any threatened or attempted change in control of the Company. The Agreements are also intended to ensure that, if a possible change in control should arise and the officer should be involved in deliberations or negotiations in connection with the possible change in control, the officer would be in a position to consider as objectively as possible whether the possible change in control transaction is in the best interests of the

Company and its stockholders without concern for his position or financial well-being. Should a change in control occur, the Agreements provide for continuity of management following the change by imposing certain obligations of continued employment on the officers.

      Under the Agreements, the Company and each of the officers agree that in the event of a change in control, such officer will remain in the Company’s employ for a period of three years from the date of the change in control (or to such officer’s normal retirement date, if earlier), subject to such officer’s right to resign during a thirty-day period commencing one year from the date of the change in control or for good reason, as defined in such officer’s Agreement. If such officer’s employment terminates within three years after a change in control for any reason other than cause as defined in the Agreements, resignation without good reason as defined in the Agreements, or disability or death, such officer will be paid a lump sum amount equal to such officer’s average annual gross income reported on Form W-2 (P-60 for Mr. Butler) for the most recent five taxable years prior to the change in control, multiplied by the lesser of 2.99 or the number of whole and fractional years left to such executive officer’s normal retirement date, plus interest. The payment may be subject to reduction to avoid adverse tax consequences.

      For purposes of the Agreements, a “change in control” would be deemed to have occurred if (i) any person or group acquires 20% or more of the Company’s issued and outstanding shares of common stock; (ii) the members of the Board as of the date of the Agreements (the “Incumbent Board”) including any person subsequently becoming a Director whose election, or nomination for election by the Company’s stockholders, was approved by a majority of the Directors then comprising the Incumbent Board, cease to constitute a majority of the Board of the Company as a result of the election of Board members pursuant to a contested election; (iii) the stockholders approve of a reorganization, merger or consolidation that results in the stockholders of the Company immediately prior to such reorganization, merger or consolidation owning less than 50% of the combined voting power of the Company; or (iv) the stockholders approve the liquidation or dissolution of the Company or the sale of all or substantially all of the Company’s assets.

      If such provisions under the applicable Agreements had become operative on January 1, 2004, the Company would have been required to pay Messrs. Hathaway, Butler, and Fazzolari the following termination payments based on compensation information available at December 31, 2004: $4,938,586, $2,407,573, and $1,688,668, respectively.

      On September 26, 1988, the Company entered into an agreement with Mr. Hathaway which provides that for purposes of calculating his retirement benefits, his years of service will be deemed to have commenced June 20, 1966.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

      Messrs. Wilburn, Jasinowski, Scheiner, Sordoni and Ms. Scanlan served as members of the Management Development and Compensation Committee during 2004 and none of them was an officer or employee of the Company or any of its subsidiaries during that time and did not serve as an executive officer of any entity for which any executive officer of the Company serves as a director or a member of its compensation committee.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Section 16(a) of the Securities Exchange Act of 1934 requires the Company’s Directors and certain of its officers to send reports of their ownership of Harsco Corporation stock and changes in ownership to the Company and the SEC, The New York Stock Exchange, Inc. and

The Pacific Exchange, Inc. SEC regulations also require the Company to identify in this Proxy Statement any person subject to this requirement who failed to file any such report on a timely basis and the Company is not aware of any such failure during 2004.

OTHER MATTERS

      The cost of this solicitation of proxies will be borne by the Company. In addition to solicitation by use of mail, employees of the Company may solicit proxies personally or by telephone or facsimile but will not receive additional compensation for these services. Arrangements may be made with brokerage houses, custodians, nominees and fiduciaries to send proxies and proxy materials to their principals and the Company may reimburse them for their expense in so doing. The Company has retained Morrow & Co. to assist in the solicitation at a cost that is not expected to exceed $10,000 plus reasonable out-of-pocket expenses.

“Householding” of Proxy Materials

      The Company and some brokers household the Annual Report to Stockholders and proxy materials, delivering a single copy of each to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker or the Company that they or the Company will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time you no longer wish to participate in householding and would prefer to receive a separate copy of the proxy materials, including the Annual Report to Stockholders, or if you are receiving multiple copies of the proxy materials and wish to receive only one, please notify your broker if your shares are held in a brokerage account or the Company if you hold registered shares. You can notify the Company by sending a written request to Harsco Corporation, 250 Poplar Church Road, Camp Hill, PA 17011 or by calling (717) 763-7064.

STOCKHOLDER PROPOSALS AND NOMINATIONS FOR PRESENTATION AT 2006 ANNUAL MEETING OF STOCKHOLDERS

      If a stockholder of the Company wishes to submit a proposal for consideration at the 2006 annual meeting of stockholders, such proposal must be received at the executive offices of the Company no later than November 22, 2005 to be considered for inclusion in the Company’s proxy statement and proxy card relating to the 2006 annual meeting. Although a stockholder proposal received after such date will not be entitled to inclusion in the Company’s proxy statement and proxy card, a stockholder can submit a proposal for consideration at the 2006 annual meeting in accordance with the Company’s By-Laws if written notice is given to the Secretary of the Company not less than 60 days nor more than 90 days prior to the annual meeting. In the event that the Company gives less than 70 days notice of the annual meeting date to stockholders, the stockholder must give notice of the proposal within ten days after the mailing of notice or announcement of the annual meeting date. In order to nominate a candidate for election as a Director at the 2006 annual meeting, a stockholder must provide written notice and supporting information to the Secretary of the Company by personal delivery or mail not later than January 27, 2006.

In the absence of a quorum at any meeting or any adjournment thereof, a majority of those present in person or by proxy and entitled to vote may adjourn such meeting from time to time. At any such adjourned meeting at which a quorum is present any business may be transacted which might have been transacted at the meeting as originally called. If a quorum is present at any meeting of stockholders and the meeting is adjourned to reconvene at a later time or date or different place, no notice need be given other than an announcement at the meeting of the place, date and time to which the meeting is adjourned, provided that if any adjournment, whether a quorum is present or not, is for more than thirty days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

Section 6. Organization. Meetings of the stockholders shall be presided over by the Chairman of the Board of Directors, or the President, a Vice President, or if none of the foregoing is present, by a chairman to be chosen by the holders of a majority of the shares of capital stock present in person or by proxy entitled to vote at the meeting. The Secretary of the Corporation, or in his absence, an Assistant Secretary, shall act as Secretary of every meeting, but if neither the Secretary nor an Assistant Secretary is present, the chairman of the meeting shall choose any person present to act as secretary of the meeting.

Section 7. Voting. Except as otherwise provided by law, at every meeting of stockholders, each stockholder of the Corporation entitled to vote at such meeting shall have one vote in person or by proxy for each share of stock having voting rights held by him and registered in his name on the books of the Corporation.

Any vote with respect to stock of the Corporation may be cast by the stockholder entitled to vote in person or by his proxy appointed by an instrument in writing, subscribed by such

stockholder or by his authorized attorney, and delivered to the secretary of the meeting; provided, however, that no proxy shall be voted or acted upon after three years from its date, unless said proxy provides for a longer period. A proxy, unless coupled with an interest, shall be revocable at will, notwithstanding any other agreement or any provision in the proxy to the contrary, but the revocation of a proxy shall not be effective until notice thereof has been given to the Secretary of the Corporation.

A proxy shall not be revoked by the death or incapacity of the maker unless, before the authority is exercised, written notice of such death or incapacity is given to the Secretary of the Corporation. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be made irrevocable regardless of whether or not the interest with which it is coupled is an interest in the stock itself or an interest in the Corporation generally.

Except as otherwise required by law or these By-laws, a quorum being present, any matter coming before any meeting of the stockholders shall be decided by a vote of a majority of the shares of capital stock entitled to vote upon such a matter present in person or by proxy at such meeting. At all elections of directors, a quorum being present, the voting shall be by ballot and a plurality of the votes cast shall elect.

Section 8. List of Stockholders. At least ten days before every meeting of stockholders, the Secretary shall prepare and make a complete list of stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of the stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

Section 9. Inspectors of Election. All elections of directors shall be by written ballot, unless otherwise provided in the Certificate of Incorporation; the vote upon any other matter need not be by ballot. In advance of any meeting of stockholders the Board of Directors shall appoint one or more inspectors of election, who need not be stockholders, to act at such meeting or any adjournment thereof. The Board of Directors may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the chairman of any such meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of the duties of inspector, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such inspector’s ability. No person who is a candidate for office shall act as an inspector.

If inspectors of election are appointed as aforesaid, they shall determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, and the authenticity, validity and effect of proxies; receive votes or ballots; hear and determine all challenges and questions in any way arising in connection with the right to vote; count and tabulate all votes; determine the result; and do such acts as may be proper to conduct the election or vote with fairness to all stockholders. If there be three inspectors of election, the decision, act or certificate of a majority shall be effective in all respects as the decision, act or certificate of all.

On request of the Chairman of the meeting or of any stockholder or his proxy, the inspectors shall make a report in writing or any challenge or question or matter determined by them, and execute a certificate of any fact found by them.

Section 10. Record Holder of Shares. The Corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends and to vote as such owner, and to hold liable for calls and assessments a person registered on its books as the owner of shares, and shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of Delaware.

Section 11. Fixing Record Date. The Board of Directors shall have the power to:

a. Fix a time not more than sixty or less than ten days before the date of any meeting of stockholders at the time as of which stockholders entitled to notice of and to vote at such meeting shall be determined; and

b. Fix a time not more than sixty days before the date fixed for the payment of any dividend or other distribution or allotment of any rights or the exercise of any rights in respect of any change, conversion or exchange of stock for any other lawful action, at the time as of which stockholders whose consent is required or may be expressed for any purpose or stockholders entitled to receive any such dividend, distribution, allotment of rights or right to exercise rights shall be determined; and all persons who are holders of record of voting stock at such time and no others shall be entitled to notice of and to vote at such meeting and only stockholders of record at the time so fixed shall be entitled to receive such dividend, distribution, allotment of rights or rights to exercise rights.

ARTICLE III

DIRECTORS

Section 1. Powers. The property, affairs and business of the Corporation generally shall be managed under the direction of the Board of Directors, who may exercise all such powers of the Corporation and do all such lawful acts and things as are not by law or the Certificate of Incorporation or the By-laws to be exercised or done by the stockholders.

Section 2. Number, Qualification, Election and Terms. Except as otherwise fixed pursuant to the provisions of Article Fourth of the Certificate of Incorporation relating to the rights of the holders of any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation to elect additional Directors under specified circumstances, the number of Directors shall be fixed from time to time by the Board of Directors but shall not be less than five nor more than twelve persons. No person who shall have attained the age of seventy-two shall be eligible for election to the Board of Directors unless he shall be nominated by a three-fourths vote of the members of the Board present. The Directors shall be elected at each annual meeting of stockholders, except as provided in Section 3 of this Article III, and each Director shall hold office until the next annual meeting of stockholders and until such Director’s successor is elected and qualified, except as required by law.

The term “entire Board” as used in these By-laws means the total number of Directors, as from time to time fixed by the Board, which the Corporation would have if there were no vacancies.

Subject to the rights of holders of any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation, nominations for the election of Directors may be made by the Board of Directors or a committee appointed by the Board of Directors or by any stockholder entitled to vote in the election of Directors generally. However, any stockholder entitled to vote in the election of Directors generally may nominate one or more persons for election as Directors at a meeting only if written notice of such stockholder’s intent to make such nomination or nominations has been given, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the Corporation not later than (i) with respect to an election to be held at an annual meeting of stockholders, ninety days prior to the anniversary date of the immediately preceding annual meeting, and (ii) with respect to an election to be held at a special meeting of stockholders for the election of Directors, the close of business on the seventh day following the date on which notice of such meeting is first given to stockholders. Each such notice shall set forth: (a) the name and address of the stockholder who intends to make the nomination and of the person or persons to be nominated; (b) a representation that the stockholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (c) a description of all arrangements or understandings between the stockholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the stockholder; (d) such other information regarding each nominee proposed by such stockholder as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission; and (e) the consent of each nominee to serve as a Director of the Corporation if so elected. The presiding officer of the meeting may refuse to acknowledge the nomination of any person not made in compliance with the foregoing procedure.

Section 3. Newly Created Directorships and Vacancies. Except as otherwise fixed pursuant to the provisions of Article Fourth of the Certificate of Incorporation relating to the rights of the holders of any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation to elect Directors under specified circumstances, newly created directorships resulting from any increase in the number of Directors and any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other cause shall be filled solely by the affirmative vote of a majority of the remaining Directors then in office, even though less than a quorum of the Board of Directors, or by a sole remaining Director. Any Director elected in accordance with the preceding sentence shall hold office until the next annual meeting of the stockholders and until such Director’s successor is elected and qualified, except as required by law. No decrease in the number of Directors constituting the Board of Directors shall shorten the term of any incumbent Director.

Section 4. Removal. Subject to the rights of any class or series of stock having a preference over the Common Stock as to dividends or upon liquidation to elect Directors under specified circumstances, any Director may be removed from office, with or without cause, only by the affirmative vote of the holders of eighty percent of the combined voting power of the then outstanding shares of stock entitled to vote generally in the election of Directors, voting together as a single class.

Section 5. Resignations. Any Director of the Corporation may resign at any time by giving written notice to the President or Secretary of the Corporation. Such resignation shall take effect at the date of the receipt of such notice or at any later time specified therein and, unless

otherwise specified therein, the acceptance of such resignation shall not be necessary to make it effective.

Section 6. Meetings. Meetings of the Board of Directors shall be held at such place within or without the State of Delaware as may from time to time be fixed by resolution of the Board or as may be specified in the call of any meeting. Regular meetings of the Board of Directors shall be held at such times and places as may at any time be fixed by resolution of the Board and may be held without further notice. A meeting of the Board shall be held without notice immediately following the annual meeting of the stockholders.

Special meetings may be held at any time upon the call of the Chairman of the Board, the President or three of the Directors then in office. Notice of any special meeting shall be given to each Director orally, telegraphically or otherwise in writing, and shall contain the place, time and date of the meeting. Meetings may be held at any time without notice if those not present waive notice of the meeting in writing.

One or more Director may participate in a meeting of the Board, or of a committee of the Board, by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other. Participation in a meeting pursuant to this paragraph shall constitute presence in person at such meeting.

Section 7. Quorum, Manner of Acting and Adjournment. At all meetings of the Board of Directors a majority of the Directors shall constitute a quorum for the transaction of business and the act of a majority of the Directors present at any meeting at which there is a quorum shall be the act of the board of Directors, except as may be otherwise specifically provided by law or by the Certificate of Incorporation. If a quorum shall not be present at any meeting of the Board of Directors, the Directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

Unless otherwise restricted by the Certificate of Incorporation or these By-laws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting, if all members of the Board consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board.

Section 8. Committees. The Board of Directors may in its discretion, by resolution adopted by a majority of the whole Board, appoint committees which shall have and may exercise, to the extent permissible under the General Corporation Law of Delaware and the Certificate of Incorporation, such powers as shall be conferred or authorized by the resolution appointing them. The Board shall have the power at any time to change the members of any such committee, to fill vacancies thereon, and to discharge any such committee.

Section 9. Indemnification of Directors and Officers. The Corporation shall, to the fullest extent permitted by applicable law, indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including any such actions by or in the right of the corporation or other entity) by reason of the fact that such person is or was a director, officer, employee or agent of the Corporation (or of such a constituent corporation, including any constituent of a constituent, absorbed in a consolidation or merger by the Corporation), or is or was serving at the request of the Corporation (or of such a constituent corporation) as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, against all expenses (including attorneys’ fees and costs), judgments, fines and amounts paid in settlement actually

and reasonably incurred by such person in connection with such action, suit or proceeding upon a determination having been made as to his good faith and conduct as required by applicable law. Expenses incurred in defending a civil or criminal action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding to the extent, if any, authorized by the Board upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation. The rights provided hereby shall not be deemed exclusive of any other such rights provided for pursuant to agreement or otherwise.

Section 10. Compensation of Directors. Unless otherwise restricted by the Certificate of Incorporation, the Board of Directors shall have the authority to fix the compensation of Directors. The Directors may be paid their expenses, if any, of attendance at each meeting of the Board of Directors and may be paid a fixed sum for attendance at each meeting of the Board of Directors or a stated salary as Director or both. No such payment shall preclude any Director from serving the Corporation in any other capacity and receiving compensation therefor. Members of committees may be allowed like compensation for attending committee meetings.

Such seal may be a facsimile, engraved or printed. If such certificate is countersigned (1) by a transfer agent other than the Corporation or its employees, or (2) by a registrar other than the Corporation or its employees, any other signature on the certificate may be a facsimile, engraved or printed. In case any officer, transfer agent, or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if he were such officer, transfer agent or registrar at the date of issue.
