GENERAL INFORMATION ABOUT THIS PROXY STATEMENT We sent you these proxy materials because Waste Management's Board of Directors is soliciting your proxy to vote your shares at the Annual Meeting. This Proxy Statement summarizes information that we are required to provide to you under the rules of the Securities and Exchange Commission ("SEC") and that is designed to assist you in voting your shares. On April 4, 2003 we began mailing these proxy materials to all stockholders of record at the close of business on March 21, 2003. WHO MAY VOTE Stockholders of Waste Management, as recorded in our stock register at the close of business on March 21, 2003, may vote at the meeting. Each share of Waste Management common stock is entitled to one vote. As of March 21, 2003, there were 591,459,383 shares of common stock outstanding and entitled to vote. HOW TO VOTE You may vote in person at the meeting or by proxy. We recommend you vote by proxy even if you plan to attend the meeting. You can always change your vote at the meeting, in which case your proxy will be revoked. HOW PROXIES WORK Waste Management's Board of Directors is asking for your proxy. There are three ways to vote by proxy: - By telephone -- You can vote by telephone by following the instructions on the proxy card; - By Internet -- You can vote on the Internet by following the instructions on the proxy card; and - By mail -- You can vote by mail by signing, dating and mailing the enclosed proxy card. Giving us your proxy means you authorize us to vote your shares at the meeting in the manner you direct. If you sign your proxy but do not give voting instructions, we will vote your shares as follows: - In favor of our director candidates; - In favor of the ratification of the independent auditors; - In favor of the amendment to the ESPP; and - Against the stockholder proposal relating to disclosure of our strategy on opposition to privatization. For any other matters that may properly come before the meeting, your shares will be voted at the discretion of the proxy holders. You may vote for all, each or none of our director candidates. You may also vote for or against the other proposals, or you may abstain from voting. You may receive more than one voting or proxy card depending on how you hold your shares. Shares registered in your name and shares held in the ESPP are covered by separate proxy cards. If you hold shares through someone else, such as a broker, you may also get material from them asking how you want to vote. You should complete and return each proxy or other voting instruction request provided to you.

REVOKING A PROXY You may revoke your proxy before it is voted by submitting a new proxy with a later date; by voting in person at the meeting; or by notifying our Corporate Secretary in writing at the following address. Your most current vote is the one that is counted unless you vote in person at the meeting. Waste Management, Inc. Attn: Corporate Secretary 1001 Fannin Street, Suite 4000 Houston, Texas 77002 QUORUM In order to carry on the business of the meeting, we must have a quorum. This means that at least a majority of the outstanding shares eligible to vote must be present at the meeting, either by proxy or in person. Abstentions and broker non-votes are counted as present at the meeting for determining whether we have a quorum. A broker non-vote occurs when a broker signs and returns a proxy but does not vote on a particular proposal because the broker does not have discretionary voting power for that particular item and has not received voting instructions from the beneficial owner. VOTES NEEDED Directors are elected by a plurality of shares present at the meeting, meaning the nine nominees that receive the highest number of votes cast in favor of their election will be elected. The ratification of the independent auditors, the approval of the amendment to the ESPP and the stockholder proposal require the favorable vote of a majority of the shares present, either by proxy or in person, and entitled to vote. Abstentions have the same effect as a vote against a matter because they are considered present and entitled to vote, but are not voted. Broker non-votes will be considered present for quorum purposes but not considered entitled to vote. Accordingly, broker non-votes will have no effect on the vote. ATTENDING IN PERSON Only stockholders, their proxy holders and our invited guests may attend the meeting. If you plan to attend, please bring identification and, if you hold shares in street name, you should bring your bank or broker statement showing your beneficial ownership of Waste Management stock in order to gain admittance to the meeting. BOARD OF DIRECTORS The Board of Directors currently consists of nine directors who are elected annually. No nominees will be recognized other than those that are nominated in accordance with our By-laws. Under the By-laws, nominations for directors must have been received between November 9, 2002 and December 9, 2002. No nominees, other than those proposed by the Board, were presented for the 2003 Annual Meeting. Consequently, no other nominees for director will be allowed at the meeting. H. Jesse Arnelle is currently a director; however, in accordance with the tenure provisions of the Company's Corporate Governance Guidelines, he is not standing for reelection. 2

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE ELECTION OF THE NINE NOMINEE DIRECTORS. DIRECTOR COMPENSATION Mr. Myers is the only director who is also an employee of the Company and receives no extra compensation for serving as a director. In 2002, non-employee directors received an annual retainer of $35,000 per year, Board meeting fees of $1,400 for each meeting attended, committee meeting fees of $1,250 for each meeting attended and reimbursement of meeting expenses. In addition, committee chairpersons received an additional $625 for each committee meeting chaired. In 2002, under our deferred compensation plan for non-employee directors, directors could choose to defer their cash compensation by receiving all or a portion of the cash that would otherwise be paid in phantom stock. Each phantom stock unit is equal in value to a share of Waste Management stock and is ultimately paid in cash. These units are measured and credited to the directors' accounts at the same time the annual retainer would otherwise be paid. Any fees that are deferred are held in the general funds of the Company. In general, deferred amounts are not paid until after the director retires from the Board. The amounts are then paid in a lump sum. In 2002, pursuant to the 1996 Stock Option Plan for Non-Employee Directors, each non-employee director also received 10,000 options to purchase the Company's common stock at the fair market value on the date of grant. Starting in 2003, the non-employee directors' annual cash retainer will be $40,000 per year. Additionally, the automatic stock option grant of 10,000 shares of common stock per year has been eliminated and, in lieu of the option grant, the non-employee directors will receive $70,000 per year in stock units. The stock units are issued under the 2003 Non-Employee Directors' Deferred Compensation Plan (the "2003 Directors' Deferred Plan"). They are valued as of the determination date (generally January 15th and July 15th of each year) and payable in shares of Waste Management common stock no earlier than one year following termination of Board service. Board meeting fees in 2003 will be $2,000 per meeting and Committee meeting fees will be $1,500 per meeting. Rather than paying a higher per meeting fee to Committee chairpersons as in the past, starting in 2003 the Committee chairs will receive an additional annual cash retainer of $10,000. Starting in 2003, Audit Committee members will also receive an additional annual cash retainer of $5,000. Non- 4

employee directors also receive reimbursement of meeting expenses. The 2003 Directors' Deferred Plan allows the non-employee directors to defer all or a portion of their cash compensation and receive payment in shares of Waste Management common stock upon termination of Board service, or upon such later date that the director may choose. MEETINGS AND BOARD COMMITTEES Last year the Board held 7 meetings. Each member of the Board of Directors attended at least 75% of the meetings of the Board and the committees on which he served. The Board appoints committees to help carry out its duties. In particular, Board committees work on key issues in greater detail than would be possible at full Board meetings. Each committee reviews the results of its meetings with the full Board, and all members of the Board are invited to attend all committee meetings. The Board has three standing committees: the Audit Committee, the Compensation Committee and the Nominating and Governance Committee. Additionally, the Board has the power to appoint additional committees, as it deems necessary. The Audit Committee currently consists of Ms. Cafferty, Mr. Clark, Mr. Pope (Chairperson), Mr. Rothmeier and Mr. Vogt, all of whom served on the Audit Committee in 2002, with the exception of Mr. Clark. Each member of the Audit Committee is "independent" as defined in the New York Stock Exchange listing standards. During 2002 the Audit Committee held 10 meetings. The duties of the Audit Committee generally are: - to review our annual audited financial statements with management and our independent auditor and recommend to the Board whether those financial statements should be included in our Annual Report on Form 10-K; - to review with management and our independent auditor our quarterly financial statements prior to the filing of the Form 10-Q; - to review with management and our independent auditor press releases relating to earnings, prior to release, as well as earnings guidance provided to analysts and rating agencies; - to review, on an annual and quarterly basis, the certifications by the CEO and CFO as to the accuracy and completeness of our reports and filings, related financial statements and disclosures under the federal securities laws; - to discuss with our independent auditor any material changes to our accounting principles and any matters required to be communicated by our independent auditor by Statement on Auditing Standards No. 61 relating to the conduct of the audit; - to retain, evaluate annually, and, if necessary, replace the independent auditors to audit our books and records; - to approve all services, including non-audit engagements, to be provided by our independent auditor prior to the engagement; - to be responsible for determining the compensation paid to our independent auditors; - to review the independence of our independent auditors; - to establish clear hiring policies for employees or former employees of our independent auditor; - to review and evaluate the lead partner of our independent audit team; - to obtain and review a report by our independent auditor, at least annually, describing the firm's internal quality-control procedures; - to review external and internal audit plans, staffing, reports and activities; 5

- to review with management, our independent auditors and internal auditors our financial reporting, accounting and auditing practices and the adequacy and effectiveness of accounting and financial controls that could affect our financial statements; - to establish procedures for the receipt, retention and treatment of complaints we receive regarding accounting, internal accounting controls or auditing matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting or auditing matters; and - to report the results of its reviews to the Board. The Audit Committee has a written charter, adopted by the Board, a copy of which is attached as Appendix A to this Proxy Statement. The Compensation Committee currently consists of Mr. Arnelle, Ms. Cafferty (Chairperson), Mr. Clark, Mr. Miller, Mr. Rothmeier and Mr. Whitworth, all of whom served on the Compensation Committee in 2002, with the exception of Mr. Clark. During 2002 the Compensation Committee met 7 times. The duties of the Compensation Committee generally are: - to establish a philosophy and policies governing all executive compensation and benefit programs; - to approve compensation for our executive officers and senior management; - to recommend to the Board new, and changes to existing, compensation and benefit plans; - to approve annual incentive compensation plan bonus goals for executive officers and senior management and grant options under our stock option plans; - to review and consider the annual evaluation of the CEO prepared by the Nominating and Governance Committee in determining the compensation of the CEO; - to annually review the Committee's performance relative to its Charter and report the evaluation results to the Board; and - to make regular reports to the Board. The Nominating and Governance Committee currently consists of Mr. Arnelle, Mr. Miller, Mr. Pope, Mr. Vogt and Mr. Whitworth (Chairperson), all of whom served on the Nominating and Governance Committee in 2002. The Nominating and Governance Committee met 5 times in 2002. The duties of the Nominating and Governance Committee generally are: - to review, and make recommendations to the Board regarding, the overall effectiveness, organization, composition and structure of the Board and its committees; - to coordinate an annual evaluation of the CEO by non-employee directors and provide the results of such evaluation to the Compensation Committee; - to coordinate an annual evaluation by the directors of the Board's performance and procedures; - to review any stockholder proposal we receive for inclusion in our proxy statement and make a recommendation to the Board to either object, support or take no position with respect to such proposal; - to review, and make recommendations to the Board regarding, corporate governance matters; - to annually review, and make recommendations to the Board with respect to, compensation of the non-employee directors; - to establish a director orientation program and monitor continuing director education; and - to make regular reports to the Board. Additionally, our Corporate Governance Guidelines, attached hereto as Appendix B, provide that the Chairman of the Nominating and Governance Committee will preside over the executive sessions of the Board 6

of Directors and will act as presiding director. Mr. Whitworth, as Chairman of the Nominating and Governance Committee, currently acts as presiding director in executive sessions of the Board of Directors. Stockholders can review our Corporate Governance Guidelines, charters of the Audit, Nominating and Governance and Compensation Committees, and our Code of Conduct by accessing our website at http://www.wm.com.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Under the federal securities laws, executive officers, directors and stockholders who own more than 10% of Waste Management common stock are required to file reports of their ownership, as well as any changes in their ownership, with the SEC and the New York Stock Exchange. They are also required to provide us with copies of any forms they file. After reviewing the copies of the forms and written representations from the executive officers and directors, we believe that during the last fiscal year, the executive officers and directors complied with all of their requirements to report their stock ownership and any changes in their ownership, with the exception of three executive officers. Each of these officers participate in our Retirement Savings Restoration Plan ("RSRP"), which supplements our 401(k) Plan and provides for contributions by regular withholdings from paychecks. In August 2002, the filing deadlines for Forms 4 were generally changed to two business days after a change in ownership, rather than ten days after the end of the month. The three officers failed to report their contributions under the RSRP into a Waste Management deferred stock fund on the first pay period after the filing deadlines were accelerated. The Forms 4 were filed as soon as practicable after the omission was realized. The three individuals and the number of deferred stock units acquired and reported on the late Forms 4 are William L. Trubeck, Executive Vice President, Operations Support and Chief Administrative Officer -- 24.257 shares; Ronald H. Jones, Vice President and Treasurer -- 8.6761 shares; and J. Drennan Lowell, President, Wheelabrator Technologies Inc. -- 12.1838 shares.

The actual gain, if any, an executive realizes will depend on the market price of Waste Management stock at the time of exercise. "In-the-money" means the market price of the stock is higher than the exercise price of the option on the date specified. 11

(1) Included in Mr. Myers' calculations are the number and value of 100,260 options owned by a trust for the benefit of his children, for which Mr. Myers serves as trustee. Mr. Myers has disclaimed beneficial ownership of these options. EMPLOYMENT AGREEMENTS We have entered into employment agreements with each of the executive officers named in the Summary Compensation Table under the section titled "Executive Compensation" on page 10. The employment agreements are for three to five-year terms, and continuously renew for one to five year periods. The agreements provide for the payment of minimum annual base salaries, a target annual bonus and participation in all Waste Management benefit plans and programs. The agreements also provide for certain severance payments and benefits in the case of termination of employment or in the event of a change in control of Waste Management. If employment ends because of death or total disability, generally salary is paid for two years, although for Mr. Damico, salary is paid through the remaining term of his agreement, which is three years. Additionally, all options vest and must be exercised within one year. Benefits are paid in accordance with the terms of our benefit plans. If we terminate the executive's employment for "cause," as defined in the employment agreements, we will pay any accrued but unpaid salary, expenses required to be reimbursed, vacation and any earned but unpaid bonuses for prior periods. Benefits will be paid in accordance with the terms of our benefit plans and all vested and unvested options or other awards will be cancelled on the date of termination. If the executive decides to terminate his employment other than for "good reason," as defined in the employment agreements, the severance is the same, except the executive will generally have 90 days after terminating his employment to exercise any already vested options. If we terminate the executive's employment without cause or the executive leaves with "good reason," as defined in the employment agreements, we will pay to the executive all accrued or earned but unpaid amounts due to him as of the date of termination plus an amount equal to two times the sum of his base salary plus his target annual bonus. Generally, all benefits will continue for two years and all stock options and other awards will continue to vest over the two-year period, to the extent the vesting is not accelerated as of the date of termination in accordance with the terms of the employment agreement. The executive will generally have two years and six months from the date of termination to exercise any of the awards other than Mr. Damico, whose agreement provides for one year after termination. In no event can an option be exercised after its term. The agreements also provide for certain severance payments and benefits if there is a "change in control," as defined in the employment agreements, of Waste Management and the executive (i) terminates his employment for good reason thereafter, (ii) is terminated without cause thereafter, or (iii) the termination of employment in (i) or (ii) occurs "in contemplation" of a change in control. In these cases, the executive will receive the same severance as described in the preceding paragraph, except the severance generally will be three times the base salary and target annual bonus instead of two times and the benefits generally will continue for three years instead of two years. The stock options and other awards will become fully vested and generally will remain exercisable for three years after termination, but not to exceed the term of the option. The executive shall also receive a prorated bonus at the maximum bonus level. Additionally, if there are any payments under the agreements due to a change in control, the executives will receive certain gross-up payments such that the net amount received by the executive pursuant to the agreement will not be reduced by any excise taxes. The employment agreements also include covenants not to compete and not to solicit employees after termination of employment, as well as confidentiality provisions as are customary, in nature and scope, for such agreements. Additionally, under his agreement, Mr. Myers receives supplemental retirement benefits in the amount of $600,000 annually, provided he remains employed by us until the fifth anniversary of his employment. In the event Mr. Myers' employment is terminated before the fifth anniversary, annual payments are pro-rated as follows: $500,000 on and after the fourth anniversary; $400,000 on and after the third anniversary; and 12

$100,000 on and after the 18-month anniversary. Mr. Myers is currently eligible to receive a retirement benefit of $400,000 per year. COMPENSATION COMMITTEE REPORT The Compensation Committee of the Board of Directors has prepared the following report regarding 2002 executive compensation. The Compensation Committee is composed entirely of non-employee, independent directors as required by the New York Stock Exchange and is responsible for establishing and administering the Company's policies governing annual compensation, long-term incentive awards, executive stock ownership, employment agreements, severance programs and other special executive benefits and perquisites. The Committee periodically evaluates the Company's compensation programs and compares them with those of other companies. This report provides specific information regarding compensation for the Company's CEO, as well as compensation information for all executives of the Company. COMPENSATION PHILOSOPHY AND OBJECTIVES OF EXECUTIVE COMPENSATION PROGRAMS It is the policy of the Company and the Committee that all compensation programs should (i) link pay to the individual's and the Company's performance and (ii) be competitive in the market to enable the Company to attract, motivate, reward and retain the executive talent required to achieve corporate objectives. The Company also focuses on compensation linked to stock price performance to provide the strongest link to enhanced stockholder value. The Committee regularly works with independent compensation consultants to assist with the design, implementation and communication of various compensation plans. The Company determines competitive levels of compensation by looking at compensation survey data for companies with revenues comparable to the Company. The Company's compensation for executives includes base salaries, annual performance-based incentives, long-term incentives, and certain executive benefits and perquisites. In designing Waste Management's compensation programs, the Compensation Committee's primary consideration is the Company's achievement of strategic business goals that serve to enhance stockholder value. Section 162(m) of the Internal Revenue Code, as amended, limits a company's ability to deduct compensation paid in excess of $1 million during any fiscal year to the Chief Executive Officer and the four highest paid officers other than the CEO, unless such compensation meets certain performance-based requirements. The Company's stock option grants currently meet the performance-based requirements under Section 162(m). The Company's Performance-Based Incentive Compensation Plan has been designed to meet the performance-based requirements under Section 162(m). The Committee may, however, authorize payment of non-deductible compensation if it determines that such action would be in the best interests of the Company and its stockholders. BASE SALARIES Base salaries for the Company's executives in 2002 were determined after reviews of the competitive market data described above. In determining base salaries, the Committee, using its discretion, considers market base salary rates, average annual salary increases for executives in companies of relative size across the country, and overall corporate financial performance. The Committee also reviews executives' individual performance in making base salary increase decisions. The Company's policy is to target base salary at the 50th percentile of the competitive market. Salary actions taken by the Compensation Committee in 2002, with respect to the executive officers, were consistent with the policies and practices described above. PERFORMANCE-BASED ANNUAL INCENTIVE COMPENSATION The Company's Performance-Based Incentive Compensation Plan links incentive compensation to the Company's achievement of specific performance goals. These goals are established at the beginning of each year by the Compensation Committee based upon corporate objectives determined by the Board. For 2002 the corporate objective was earnings before interest, taxes, depreciation and amortization (EBITDA). The 13

Compensation Committee used its discretion and reduced the maximum incentive payments authorized under the Performance-Based Incentive Compensation Plan based on the executive officers' achievement of the following goals: (1) Return on Capital Employed (measured against internal objectives); (2) Earnings Per Share (measured against internal year-over-year continuous improvement targets) ; (3) Individual performance (measured against specific personal performance objectives). Each performance goal, including the specific criteria for such goal, is weighted based upon the relative importance of each goal as determined by the Compensation Committee. A bonus target, ranging up to 115% of base salary, is established for each of the Company's executives under the Company's Performance-Based Incentive Compensation Plan. These bonus targets are based upon individual position, level of responsibility and each individual's ability to impact the Company's success. In 2002, the Company targeted annual incentive compensation at the 75th percentile of the market for comparable performance. Actual bonus awards are determined based on the Company's and the individual executive's achievement of the performance goals and can range from 0% to 200% of bonus target. Targeted bonuses for the named executive officers in 2002 generally fell between the market 50th and 75th percentiles. Actual bonuses for 2002 were less than target since Waste Management's performance was below the established goals. LONG-TERM INCENTIVE COMPENSATION The Company believes that its executives should have an ongoing stake in the long-term success of the Company. We also believe these key employees should have a considerable portion of their total compensation tied to the Company's stock price performance, which is directly linked to stockholder value. The Company targets long-term incentive compensation to be between the 50th and 75th percentile of the competitive compensation data described above. The Company primarily uses stock options to deliver long-term incentives to executive officers. Stock options provide a strong link between pay and performance, since executives only realize value from stock options if the Company's share price rises after the date of grant. The Compensation Committee annually reviews competitive market data to determine appropriate stock awards to executives. All stock options in 2002 were granted with exercise prices at 100% of fair market value of the Company's common stock at the time of grant. The aggregate 2002 stock option grants for named officers approximated the 75th percentile of the competitive compensation data. Restricted stock is used periodically for attraction and retention purposes. 2002 CHIEF EXECUTIVE OFFICER COMPENSATION BASE SALARY The Committee established Mr. Myers' annualized base salary at $850,000 in November 1999 when he joined the Company. This base salary was set below the 1999 competitive market 50th percentile in recognition of the stock-based compensation awards provided to Mr. Myers when he was hired. Mr. Myers did not receive an adjustment to his base salary in 2000 or in 2001. The Committee increased Mr. Myers' base salary to $1,000,000 during 2002, bringing Mr. Myers' base salary to the competitive market 50th percentile. ANNUAL BONUS Mr. Myers received a bonus of $907,531 for 2002, based on the achievement of performance goals described above, under "Performance-Based Annual Incentive Compensation." 14

LONG-TERM INCENTIVES Mr. Myers received an option grant of 400,000 options in March 2002 under the Company's annual stock option grant process. The grant of these stock options was made pursuant to his performance as evaluated by the Board of Directors. The options were granted with exercise prices at 100% of fair market value of the Company's common stock on the date of grant. STOCK OWNERSHIP POLICY The Company adopted a stock ownership policy during 2002. Executives at the Senior Vice President level and above, as well as select executives at the Vice President level, are subject to the ownership policy. The objectives of the ownership policy are to ensure that Company executives (1) hold a meaningful amount of Company stock, and (2) retain shares acquired from the Company's equity compensation programs for a period of time. To achieve these objectives, the Company implemented stock ownership guidelines that vary by level and are expressed as a fixed number of shares. The Chief Executive Officer is expected to own approximately 166,000 shares. Executives at the Senior Vice President level and above have five years to meet the guidelines and Vice Presidents have seven years. Shares owned outright, deferred stock units in the RSRP and shares held in the 401(k) plan count towards meeting the guideline. Executives are required to hold 100% of the after-tax profit shares from Company equity compensation programs for one year after exercise or vesting. At the end of the holding period, executives who have not met their ownership guidelines are required to continue to hold 50% of the net profit shares. SUMMARY The Compensation Committee believes that executive compensation for 2002 adequately reflects its policy to align compensation with overall business strategy, values and management initiatives and to ensure the Company's goals and performance are consistent with the interests of its stockholders. The Compensation Committee of the Board of Directors Pastora San Juan Cafferty, Chairperson H. Jesse Arnelle Frank M. Clark, Jr. Robert S. Miller Steven G. Rothmeier Ralph V. Whitworth COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During 2002 Ms. Cafferty and Messrs. Arnelle, Miller, Rothmeier and Whitworth served on the Compensation Committee. During 2002 no member of the Compensation Committee was an officer or employee of Waste Management; however, Mr. Miller served as interim President and Chief Executive Officer from August 1999 until November 1999. During 2002 none of our executive officers served as: - a member of a compensation committee of another company, one of whose executive officers served on our Compensation Committee; - a director of another company, one of whose executive officers served on our Compensation Committee; or - a member of a compensation committee of another company, one of whose executive officers served as one of our directors. 15

RELATED PARTY TRANSACTIONS Mr. Carl Vogt, a member of the Board of Directors, is "Of Counsel" to Fulbright & Jaworski L.L.P., a nationally and internationally based law firm. During 2002 we retained Fulbright & Jaworski L.L.P. to provide legal services. The amount of legal fees paid to Fulbright & Jaworski L.L.P. did not exceed 5% of the law firm's gross revenues for its last fiscal year, and is, therefore, not considered material.

AUDIT COMMITTEE REPORT The role of the Audit Committee is, among other things, to oversee the Company's financial reporting process on behalf of the Board of Directors, to recommend to the Board whether the Company's financial statements should be included in the Company's Annual Report on Form 10-K and to select the independent auditor for ratification by stockholders. Company management is responsible for the Company's financial statements as well as for its financial reporting process, accounting principles and internal controls. The Company's independent auditors are responsible for performing an audit of the Company's financial statements and expressing an opinion as to the conformity of such financial statements with generally accepted accounting principles. The Audit Committee has reviewed and discussed the Company's audited financial statements as of and for the year ended December 31, 2002 with management and the independent auditors, and has taken the 16

following steps in making its recommendation that the Company's financial statements be included in its annual report: - First, the Audit Committee discussed with Ernst & Young, the Company's independent accountants for fiscal year 2002, those matters required to be discussed by Statement on Auditing Standards No. 61, including information regarding the scope and results of the audit. These communications and discussions are intended to assist the Audit Committee in overseeing the financial reporting and disclosure process. - Second, the Audit Committee discussed with Ernst & Young its independence and received from Ernst & Young a letter concerning independence as required under applicable independence standards for auditors of public companies. This discussion and disclosure helped the Audit Committee in evaluating such independence. The Audit Committee also considered whether the provision of other non-audit services to the Company is compatible with the auditor's independence. - Finally, the Audit Committee reviewed and discussed, with the Company's management and Ernst & Young, the Company's audited consolidated balance sheets at December 31, 2002, and consolidated statements of income, cash flows and stockholders' equity for the fiscal year ended December 31, 2002, including the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of the disclosure. The Committee has also discussed with the Company's internal and independent auditors the overall scope and plans of their respective audits. The Committee meets periodically with both the internal and independent auditors, with and without management present, to discuss the results of their examinations and their evaluations of the Company's internal audit. The members of the Audit Committee are not engaged in the accounting or auditing profession and, consequently, are not experts in matters involving auditing or accounting. In the performance of their oversight function, the members of the Audit Committee necessarily relied upon the information, opinions, reports and statements presented to them by Company management and by the independent auditors. Based on the reviews and discussions explained above (and without other independent verification), the Audit Committee recommended to the Board (and the Board has approved) that the Company's financial statements be included in its annual report for its fiscal year ended December 31, 2002. The Committee and the Board have also recommended the selection of Ernst & Young as the Company's independent auditors for fiscal year 2003. The Audit Committee of the Board of Directors John C. Pope, Chairperson Pastora San Juan Cafferty Frank M. Clark, Jr. Steven G. Rothmeier Carl W. Vogt RATIFICATION OF INDEPENDENT AUDITORS (ITEM 2 ON THE PROXY CARD) The next proposal on the agenda for the Annual Meeting will be a proposal to ratify the Board's appointment of Ernst & Young as our independent auditors for fiscal year 2003. On March 21, 2002 we dismissed Arthur Andersen LLP as our independent auditors and determined to appoint Ernst & Young as our new independent auditors. This determination followed our decision to seek proposals from independent accountants to audit our financial statements and was approved by the Board upon the recommendation of the Audit Committee. 17

Arthur Andersen's report on our consolidated financial statements for the year ended December 31, 2001 did not contain an adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope or accounting principles. For the fiscal years ended December 31, 2001 and 2000 and through the date of dismissal, there were no disagreements with Arthur Andersen on any matter of accounting principle or practice, financial statement disclosure, or auditing scope or procedure which, if not resolved to Arthur Andersen's satisfaction, would have caused them to make reference to the subject matter in connection with their report on our consolidated financial statements for fiscal years 2001 and 2000. For the fiscal years ended December 31, 2001 and 2000 and through the date of dismissal, we did not consult Ernst & Young with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our consolidated financial statements, or any other matters or reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K. Representatives of Ernst & Young will be at the Annual Meeting. They will be able to make a statement if they want, and will be available to answer any appropriate questions stockholders may have. AUDIT FEES Ernst & Young's fees for our 2002 audit and the reviews of our quarterly financial statements were approximately $8.3 million. AUDIT-RELATED FEES Ernst & Young's fees for audit-related services during 2002 were approximately $0.7 million, which was comprised of approximately $0.6 million of subsidiary audits required by contracts and approximately $0.1 million of employee benefit plan audits. TAX FEES Ernst & Young's fees for tax services during 2002 were approximately $0.1 million. These services were for certain tax assistance in foreign jurisdictions. FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES There were no fees paid to Ernst & Young in 2002 for professional services with respect to financial information systems design and implementation. ALL OTHER FEES There were no fees paid to Ernst & Young in 2002 for any other professional services. As set forth in the Audit Committee Report on page 16, the Audit Committee has considered whether the provision of these non-audit services is compatible with maintaining auditor independence. In January 2003, the SEC adopted new auditor independence rules that amend the fee categories and disclosure requirements for fees paid to independent auditors. Although the new disclosure requirements are not required until our 2004 Proxy Statement, we have presented the audit fees and provided supplemental disclosure of the audit-related and tax fees based on the guidance in the new disclosure requirements. THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE RATIFICATION OF ERNST & YOUNG LLP AS THE COMPANY'S INDEPENDENT AUDITORS FOR FISCAL YEAR 2003. 18

PROPOSAL TO AMEND THE COMPANY'S EMPLOYEE STOCK PURCHASE PLAN (ITEM 3 ON THE PROXY CARD) DESCRIPTION OF THE AMENDMENT The Board of Directors believes it is in our best interests to encourage stock ownership by our employees. Accordingly, the Board of Directors established the Employee Stock Purchase Plan, which was approved by stockholders at our 1997 Annual Meeting. An aggregate of 1,000,000 shares of common stock was originally authorized for issuance under the ESPP. Stockholders approved an increase in the number of shares authorized for issuance under the ESPP to 2,250,000 at the 2000 Annual Meeting. As of March 21, 2003, approximately 45,000 employees were eligible to participate in the ESPP. As of March 21, 2003, less than 90,000 shares remained available for issuance. Therefore, the Board of Directors will present a proposal to increase the number of shares authorized for issuance by an additional 2,000,000 shares of common stock by amending the ESPP. DESCRIPTION OF THE ESPP The ESPP permits eligible employees that enroll in the ESPP to purchase shares of common stock at a discount. On the last day of each six month period between January 1 and June 30 and July 1 and December 31 (each, an "Offering Period"), each employee who is enrolled in the ESPP will automatically purchase a number of shares of common stock determined by dividing such employee's payroll deductions accumulated in the ESPP during such Offering Period by the Offering Price. The Offering Price of each of the shares purchased in a given Offering Period shall be the lower of: (i) 85% of the fair market value of a share of common stock on the first day of the Offering Period, or (ii) 85% of the fair market value of a share of common stock on the last day of the Offering Period. If an employee withdraws from participation during an Offering Period, the monies contributed to the Plan are refunded immediately without interest. On March 21, 2003, the fair market value of our common stock was approximately $22.60. The ESPP is administered by the Administrative Committee of the Waste Management Employee Benefit Plans, a committee appointed by the Board of Directors. The Administrative Committee has the authority to interpret all provisions of the ESPP. Generally, all full-time employees who have been employed for at least 30 days prior to an enrollment date are eligible to participate in the ESPP. Eligible employees may elect to participate in the ESPP by completing an enrollment agreement we provide that authorizes payroll deductions from the employee's pay. The payroll deduction may not exceed ten percent of the employee's gross pay. In addition, an employee cannot contribute more than any amount which would generally (a) result in the employee owning common stock and/or options to purchase common stock making up five percent or more of our outstanding capital stock, or (b) permit such employee to purchase more than $25,000 of common stock in that year. All payroll deductions for the ESPP are placed in our general corporate account. No interest accrues on the payroll deductions, and an employee participating in the ESPP may not make any additional payments into the account. Employees may purchase common stock under the ESPP only through payroll deductions. The Board of Directors may amend the ESPP at any time. However, the ESPP may not be amended in any way that will cause rights issued thereunder to fail to meet the requirements for employee stock purchase plans as defined in Section 423 of the Internal Revenue Code of 1986, as amended (the "Code"), including stockholder approval if required. The ESPP will terminate on (i) the date that participating employees become entitled to purchase an aggregate number of shares greater than the number of shares remaining available for purchase, or (ii) the date on which the ESPP is terminated by the Board of Directors. Participation in the ESPP is discretionary, and participants can contribute up to ten percent of their gross pay, subject to the limitations described above. Additionally, the value of the common stock purchased will vary based on the fair market value of our common stock on the first and last days of the Offering Period. Accordingly, the number of shares that may be purchased by the five most highly compensated executive 19

officers listed in this Proxy Statement, the executive officers as a group, the non-executive directors as a group and the non-executive officers as a group in the future is not currently determinable. Non-employee directors of the Company are not eligible to participate in the ESPP. FEDERAL INCOME TAX CONSEQUENCES The ESPP is intended to be an "employee stock purchase plan" as defined in Section 423 of the Code, which provides that an employee does not have to pay any federal income tax when he elects to participate in the ESPP or when he purchases shares of common stock in accordance with the terms of the ESPP. The employee is, however, required to pay federal income tax on the difference, if any, between the price at which he sells the shares received under the ESPP and the price paid for them. The foregoing does not constitute a complete statement of the federal income tax effects under the ESPP, and each participant in the ESPP should consult with his or her own tax advisor to determine the particular tax effects of participation in the ESPP and transactions in shares received thereunder. The foregoing description of the ESPP is qualified in its entirety by, and should be read in conjunction with, the text of the ESPP, a copy of which, as proposed to be amended, is attached hereto as Appendix C. The affirmative vote of the holders of a majority of the shares of Waste Management common stock present or represented by proxy and entitled to vote at the Annual Meeting of Stockholders is required for approval of the amendment to the ESPP. THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE APPROVAL OF THE AMENDMENT TO THE EMPLOYEE STOCK PURCHASE PLAN. EQUITY COMPENSATION PLANS INFORMATION The following is a summary of all of our equity compensation plans, including plans that were assumed through acquisitions and individual arrangements that provide for the issuance of equity securities as compensation, as of December 31, 2002.

STOCKHOLDER PROPOSAL (ITEM 4 ON THE PROXY CARD) The following proposal was submitted by the AFSCME Employees Pension Plan, 1625 L Street, N.W., Washington, D.C. 20036, which owns 7,107 shares of Waste Management common stock. The proposal is co-sponsored by the New York City Employees' Retirement System, c/o Comptroller of the City of New York, 1 Centre Street, New York, NY 10007-2341, which owns 965,123 shares of Waste Management common stock. STOCKHOLDER PROPOSAL RESOLVED that shareholders of Waste Management, Inc. ("WMI" or the "Company") request that the Board of Directors report to shareholders on the effect on WMI's business strategy of measures to oppose privatization of the provision of waste collection, disposal, transfer and recycling services. For purposes of this proposal, "privatization" means the shift from provision of such services by governmental entities to provision by private companies. Measures to oppose privatization should include initiatives, including "living wage" requirements, whose purpose or effect is to prohibit privatization or make the provision of privatized services more expensive for private service providers. STOCKHOLDER SUPPORTING STATEMENTS Our Company provides solid waste services to commercial, industrial and residential customers. As explained in WMI's most recent filing on Form 10-K, residential services are provided under a contract with, or franchise granted by, a municipality or regional authority giving WMI the exclusive right to service all or a portion of the homes in that jurisdiction. According to a June 28, 2001 industry report by Salomon Smith Barney, the municipal segment makes up 20% of WMI's core solid waste business. The report characterizes the municipal segment, which offers "less attractive economics," as the "most competitive." We are concerned that measures to oppose privatization may make this segment even less attractive from a financial perspective. In recent years, there has been significant opposition to privatization. States have imposed requirements designed to ensure accurate cost comparisons, require a minimum level of cost savings before services can be contracted out, require contractors to provide "prevailing" wages and benefits and assistance to displaced public employees, and limit contract terms. Some states have even prohibited outright the privatization of certain kinds of services: for example, Illinois prohibits the privatization of correctional services. Similarly, "living wage" laws, which require employers who accept service contracts, operating grants, or tax abatements from local governments to pay more than the federal minimum wage, have proliferated. According to the community organization ACORN, 91 municipalities and counties have adopted living wage ordinances, and campaigns are underway in 75 additional locations. The Employment Policy Foundation states that "[t]he high monetary and potential legal costs imposed by [living wage] ordinances serve to make municipal contracting more risky and less attractive." We believe that opposition to privatization will likely increase. The Wall Street Journal reported on November 20, 2001, that such opposition had begun to increase as a result of the September 11th terrorist attacks, although it noted that the "beginnings of a backlash were stirring" before the attacks. The article pointed to the decision to federalize airport security workers and the postponement of planned privatizations of certain Pentagon back-office and mapping operations. In October 2002, the city of New Orleans shelved a planned privatization of its water and sewer operations, which would have provided inadequate cost savings. We believe shareholders should be better informed regarding the risks created by measures to oppose privatization and the way WMI weighs those risks when establishing business strategy. We urge shareholders to vote FOR this proposal. 21

WASTE MANAGEMENT RESPONSE TO STOCKHOLDER PROPOSAL The proponent is the AFSCME Employees Pension Plan ("AFSCME"), which is the pension plan for the American Federation of State, County and Municipal Employees (the "Union"). The proposal is co-sponsored by the New York City Employees' Retirement System. The AFSCME submitted this same stockholder proposal last year, and it was included in our Proxy Statement last year. At last year's Annual Meeting, the proposal received only 3.2% of the total shares represented at the meeting and entitled to vote and, in accordance with proxy rules, is included in this year's Proxy Statement because it received more than 3.0% of the shares represented at the meeting and entitled to vote. The Union is a union that represents state, county and municipal employees. Obviously, to the extent that a municipality decides to privatize, members of the Union may lose their jobs, and the Union loses members. The Union website contains extensive resources relating to efforts and strategies of the Union to oppose privatization of governmental services, including waste collection and disposal. Included among these resources are excerpts from several articles maligning us and our activities in the municipal sector. Thus, although the proposal is drafted in such a way that it appears to relate to matters of general interest to all stockholders, we believe the proponent is using the proposal as one of many tactics designed to assist the Union in its opposition to our efforts to enter into municipal contracts. We believe the proponent is acting on behalf of the Union in seeking to compel us to report on our business strategy to enable the Union to gain our private strategic business information for its own ends. Although the proponent claims that it is not an affiliate of the Union, we believe that the distinction is legalistic rather than actual. We do not believe that the motivation for the proposal has any connection to what is fair and equitable for our stockholders. Instead, we believe the proposal was lodged in direct support of, and to gain additional publicity in connection with, the Union's own efforts to oppose such privatization. We believe that forcing us to report on the effect on our business strategy of measures to oppose privatization would not benefit any group other than the Union. Such information would provide the Union with insights into our strategic planning that in turn would assist the Union in its efforts to oppose privatization of the provision of waste collection and disposal services. We believe that such a proposal would be of no benefit to our stockholders at large and, indeed, would disadvantage us and our stockholders. Consequently, we believe that the information requested would not be of significance to any persons other than a group attempting to damage such portion of our business. We believe the Union is such a group. THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE AGAINST THE ADOPTION OF THIS PROPOSAL. OTHER MATTERS Neither we nor our directors intend to bring any matters before the Annual Meeting other than: - the election of nine directors; - the ratification of our independent auditors; and - the proposal to amend the ESPP. Also, we have no present knowledge that any other matters will be presented by others for action at the meeting, other than the stockholder proposal described above. If any other matters are properly presented, your proxy card authorizes the people named as proxies to vote as they think best. OTHER INFORMATION STOCKHOLDER PROPOSALS FOR THE 2004 ANNUAL MEETING Eligible stockholders who want to have proposals considered for inclusion in the Proxy Statement for our 2004 Annual Meeting should notify our Corporate Secretary. The written proposal must be received at our 22

offices no later than December 9, 2003 and no earlier than November 9, 2003. A stockholder must have been the registered or beneficial owner of at least 1% of our outstanding common stock or stock with a market value of $2,000 for at least one year before submitting the proposal. Also, the stockholder must continue to own the stock through the date that the 2004 Annual Meeting is held. EXPENSES OF SOLICITATION We pay the cost of preparing, assembling and mailing this proxy-soliciting material. In addition to the use of the mail, proxies may be solicited personally, by Internet, telephone or telegraph, or by Waste Management officers and employees without additional compensation. We pay all costs of solicitation, including certain expenses of brokers and nominees who mail proxy materials to their customers or principals. Also, Mellon Investor Services has been hired to help in the solicitation of proxies for the 2003 Annual Meeting for a fee of approximately $7,000 plus associated costs and expenses. ANNUAL REPORT A copy of our 2002 Annual Report to Stockholders, including our Annual Report on Form 10-K, which includes our financial statements for fiscal year 2002, is enclosed with this Proxy Statement.

While the Audit Committee has the responsibilities and powers set forth in this Charter, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company's financial statements are complete and accurate and are in accordance with generally accepted accounting principles and the Applicable Rules and Regulations. These are the responsibilities of management and the independent auditor. It is also not the duty of the Audit Committee to conduct investigations, or to assure compliance with laws and regulations and the Company's Code of Ethical Conduct. The Audit Committee shall have the authority to engage outside advisors, including legal, accounting or other consultants to advise the Audit Committee or as it determines necessary to carry out its duties.

CORPORATE AUTHORITY & RESPONSIBILITY All corporate authority resides in the Board of Directors as the representative of the stockholders. The Board delegates authority to management to pursue the Company's mission. Management, not the Board, is responsible for managing the Company. The Board retains responsibility to recommend candidates to the stockholders for elections to the Board of Directors. The Board retains responsibility for selection and evaluation of the Chief Executive Officer (the "CEO"), oversight of succession plans, determination of senior management compensation, approval of the annual budget, and review of systems, procedures and controls.

The Board shall have responsibility for determining any qualifications of committee members, including whether any member of the Audit Committee is an "Audit Committee Financial Expert". NON-EMPLOYEE DIRECTOR "Non-Employee Director" means a person who is independent of management and free from any relationship with the Company or otherwise that, in the opinion of the Board of Directors, would interfere in the exercise of independent judgment as a director and who meets the independence requirements and such other qualifications as imposed by the New York Stock Exchange or under applicable rules or regulations (collectively, the "Applicable Rules and Regulations"). No officer or employee of the Company or its subsidiaries shall be qualified as a "Non-Employee Director."

To facilitate the Board's consideration, (i) the CEO and other employee directors shall submit a resignation as a matter of course upon retirement, resignation, or other significant change in professional roles, and (ii) all Non-Employee Directors shall submit a resignation as a matter of course upon retirement, a change in employer, or other significant change in their professional roles and responsibilities.

INDEPENDENT ADVICE The Board may seek legal or other expert advice from a source independent of management. Generally this would be with the knowledge of the CEO. With regard to investigations approved by resolution of the Board and in which the Board believes there may be a potential conflict of interest, the Board shall select independent outside counsel, accountants and other advisors it determines are independent of the Company and management, and the cost of such advisors will be paid by the Company. BUSINESS TRANSACTIONS Any transaction (excluding Board approved compensation and normal expense reimbursement) between or involving the Company or any of its affiliates and a member of the Board or member of the Company's B-2

senior leadership team or any member of their immediate family sharing the same household, including any entity (whether for profit or not for profit) at which they serve as an officer, director or employee, or in which they hold more than an aggregate 5% equity stake (in each case a "Covered Person"), whether acting on their own behalf or on behalf of a third party, must be approved in advance by the Board.

5. Eligibility to Participate in the Plan. Subject to limitations imposed by Section 423(b) of the Code, each Eligible Employee who is employed by the Company or a Participating Subsidiary for 30 days prior to an Enrollment Date shall be eligible to participate in the Plan for the Offering Period beginning on that Enrollment Date. 6. Election to Participate in the Plan. (a) Each Eligible Employee may elect to participate in the Plan by completing an enrollment agreement in the form provided by the Company and filing such enrollment agreement with the Company prior to the applicable Enrollment Date, unless the Committee establishes another deadline for filing the enrollment agreement with respect to a given Offering Period. (b) Unless a Participant withdraws from participation in the Plan as provided in Section 10 or authorizes a different payroll deduction by filing a new enrollment agreement prior to the Enrollment Date of a succeeding Offering Period, a Participant who is participating in an Offering Period as of the Exercise Date of such Offering Period shall be deemed to have (i) elected to participate in the immediately succeeding Offering Period and (ii) authorized the same payroll deduction percentage for such immediately succeeding Offering Period as was in effect for such Participant immediately prior to such succeeding Offering Period. 7. Payroll Deductions. (a) All Participant contributions to the Plan shall be made only by payroll deductions. Each time a Participant files the enrollment agreement with respect to an Offering Period, the Participant shall authorize payroll deductions to be made during the Offering Period in an amount from 1% to 10% (in whole percentages) of the Eligible Compensation that the Participant receives on each payroll date during such Offering Period. Payroll deductions for a Participant shall commence on the first payroll date following the Enrollment Date and shall end on the last payroll date in the Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided below in Section 10. (b) All payroll deductions made for a Participant shall be deposited in the Company's general corporate account and shall be credited to the Participant's account under the Plan. No interest shall accrue on or be credited with respect to the payroll deductions of a Participant under the Plan. A Participant may not make any additional contributions into such account. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions. (c) Except as provided in Section 10, a Participant may not change his contribution election during an Offering Period. (d) Notwithstanding the foregoing provisions of this Section 7, no Participant may make payroll deductions during any calendar year in excess of $21,250, or such other limit as may be established by the Committee, in its discretion. 8. Grant of Options. (a) On the Enrollment Date of each Offering Period, subject to the limitations set forth in Sections 3 and 8(b) hereof, each Eligible Employee shall be granted an option to purchase on the Exercise Date for such Offering Period a number of whole and fractional shares of the Company's Common Stock determined by dividing such Eligible Employee's payroll deductions accumulated during the Offering Period by the Exercise Price established for such Offering Period. (b) Notwithstanding any provision of the Plan to the contrary, no Eligible Employee shall be granted an option under the Plan (i) if, immediately after the grant, such Eligible Employee (or any other person whose stock would be attributed to such Employee pursuant to Section 424(d) of the Code) would own stock and/or hold outstanding options to purchase stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or of any Subsidiary of the Company, or (ii) which permits such Eligible Employee's rights to purchase stock under all employee stock purchase plans of the Company and its C-3

Subsidiaries to accrue at a rate which exceeds $25,000 of fair market value of such stock (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time. 9. Automatic Purchase. Unless a Participant withdraws from the Plan as provided below in Section 10, the Participant's option for the purchase of shares will be exercised automatically on each Exercise Date for which an enrollment agreement has been filed, and the maximum number of whole and fractional shares subject to the option will be purchased for the Participant at the Exercise Price established for that Offering Period, as provided above in Section 8. 10. Withdrawal; Termination of Employment. (a) A Participant may withdraw all of the payroll deductions credited to the Participant's account for a given Offering Period by providing written notice to the Company no later than 45 days prior to the last day of such Offering Period. A Participant shall not be permitted to make a partial withdrawal of the payroll deductions credited to his account. All of the Participant's payroll deductions credited to the Participant's account will be paid to him promptly after receipt of the Participant's notice of withdrawal, the Participant's participation in the Plan will be automatically terminated, and no further payroll deductions for the purchase of shares hereunder will be made. Payroll deductions will not resume on behalf of a Participant who has withdrawn from the Plan, unless written notice is delivered to the Company within the enrollment period preceding the commencement of a new Offering Period directing the Company to resume payroll deductions. (b) Upon termination of the Participant's Continuous Employment prior to the Exercise Date of the Offering Period for any reason, including retirement or death, the payroll deductions credited to the Participant's account will be returned to the Participant or, in the case of death, to the Participant's estate, and the Participant's options to purchase shares under the Plan will be automatically terminated. (c) In the event a Participant ceases to be an Eligible Employee during an Offering Period, the Participant will be deemed to have elected to withdraw all payroll deductions credited to his account from the Plan. In such circumstance, the payroll deductions credited to the Participant's account will be returned to the Participant, and the Participant's options to purchase shares under the Plan will be terminated. 11. Transferability. Options to purchase Common Stock granted under the Plan are not transferable, in any manner, by a Participant and are exercisable only by the Participant. 12. Reports. Individual accounts will be maintained for each Participant in the Plan. Following each Exercise Date, statements of account will be given to Participants who have purchased shares under Section 9. Such statements will set forth the amounts of payroll deductions, the per share purchase price, the number of shares purchased and the remaining cash balance, if any. 13. Adjustments Upon Changes in Capitalization. (a) If the outstanding shares of Common Stock are increased or decreased, or are changed into or are exchanged for a different number or kind of shares, as a result of one or more reorganizations, restructurings, recapitalizations, reclassifications, stock splits, reverse stock splits, stock dividends or the like, upon authorization of the Committee, appropriate adjustments shall be made in the number and/or kind of shares, and the per share purchase price thereof, which may be issued in the aggregate and to any Participant upon exercise of options granted under the Plan. (b) In the event of the proposed dissolution or liquidation of the Company, each Offering Period will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Committee. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each option under the Plan shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor C-4

corporation, unless the Committee determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, that the Participant shall have the right to exercise the option as to all of the optioned stock, including shares as to which the option would not otherwise be exercisable. If the Committee makes an option fully exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Committee shall notify the Participant that the option shall be fully exercisable for a stated period, which shall not be less than 10 days from the date of such notice, and the option will terminate upon the expiration of such period. (c) In all cases, the Committee shall have full discretion to exercise any of the powers and authority provided under this Section 13, and the Committee's actions hereunder shall be final and binding on all Participants. No fractional shares of stock shall be issued under the Plan pursuant to any adjustment authorized under the provisions of this Section 13. 14. Amendment of the Plan. The Board may at any time, or from time to time, amend the Plan in any respect; provided, however, that the Plan may not be amended in any way that will cause rights issued under the Plan to fail to meet the requirements for employee stock purchase plans as defined in Section 423 of the Code or any successor thereto, including, without limitation, shareholder approval, if required. 15. Termination of the Plan. The Plan and all rights of Eligible Employees hereunder shall terminate: (a) on the Exercise Date that Participants become entitled to purchase a number of shares greater than the number of reserved shares remaining available for purchase under the Plan; or (b) at any time, at the discretion of the Board. In the event that the Plan terminates under circumstances described in Section 15(a) above, reserved shares remaining as of the termination date shall be sold to Participants on a pro rata basis. 16. Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 17. Shareholder Approval. The Plan shall be subject to approval by the shareholders of the Company within twelve months after the date the Plan is adopted by the Board of Directors. If such shareholder approval is not obtained prior to the first Exercise Date, the Plan shall be null and void and all Participants shall be deemed to have withdrawn all payroll deductions credited to their accounts on such Exercise Date pursuant to Section 10. 18. Conditions upon Issuance of Shares. (a) The Plan, the grant and exercise of options to purchase shares of Common Stock under the Plan, and the Company's obligation to sell and deliver shares upon the exercise of options to purchase shares shall be subject to all applicable federal, state and foreign laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may, in the opinion of counsel for the Company, be required. Notwithstanding anything in the Plan to the contrary, share certificates shall not be delivered to Participants until the later of (i) the date on which the applicable holding period to avoid a disqualifying disposition (within the meaning of Code Section 421) expires, or (ii) the date that a Participant specifically requests a certificate for shares purchased pursuant to the Plan. C-5

(b) The Company may make such provisions, as it deems appropriate, for withholding by the Company pursuant to all applicable tax laws of such amounts as the Company determines it is required to withhold in connection with the purchase or sale by a Participant of any Common Stock acquired pursuant to the Plan. The Company may require a Participant to satisfy any relevant tax requirements before authorizing any issuance of Common Stock to such Participant. C-6
