SLM CORPORATION ABOUT VOTING Who may vote? Only SLM Corporation shareholders who owned common stock at the close of business on March 17, 2003, the record date for the Annual Meeting, can vote. We refer to SLM Corporation as Sallie Mae or the Corporation. How are my votes counted? In the election of directors, shares are entitled to cumulative voting, which means that each share of common stock is entitled to the number of votes equal to the number of directors to be elected. As a result, each share is entitled to 15 votes in the election of directors. If you vote in person, you may cumulate your votes and give one nominee all of your votes or you may distribute your votes among the nominees in any manner. If you vote by proxy, your votes will be cast and cumulated so as to elect the maximum number of the nominees named on the proxy card, except that none of your votes will be cast for any nominee for whom you instruct that the vote be withheld. The 15 nominees who receive the greatest number of votes cast and entitled to be voted at the Annual Meeting will be elected. Approval of the amendment to the Corporation's Certificate of Incorporation requires the affirmative vote of at least a majority of shares outstanding on the record date, with each share of stock entitled to one vote. Abstentions and shares that are not voted, including shares for which a broker does not have discretionary voting authority, have the same effect as votes against this item. Approval of other matters at the Annual Meeting requires an affirmative vote of at least a majority of the votes present or represented and entitled to be voted on the matter, with each share of stock entitled to one vote. Abstentions have the same effect as votes against the matter. Shares that are not voted on a matter, including shares for which a broker does not have discretionary voting authority, do not affect the vote. How do I vote? You may vote in person at the Annual Meeting or you may vote by proxy. We recommend that you vote by proxy even if you plan to attend the Annual Meeting. The process of voting by proxy differs slightly, based on how your share ownership is recorded. Your share ownership is recorded in one of three ways: direct ownership, recorded by the stock transfer agent for the Corporation, the Bank of New York; beneficial ownership recorded through a brokerage or bank account; or beneficial ownership recorded by the Corporation's 401(k) Plan Trustee. If your ownership is recorded directly, you will receive a proxy card. If your share ownership is beneficial, your broker, bank and/or the 401(k) Plan Trustee will issue you a voting instruction form that you use to instruct them how to vote your shares. Your broker, bank or the 401(k) Plan Trustee must follow your voting instructions. If you receive a voting instruction card from your broker or bank, you may vote those shares by mail, telephonically by calling the telephone number shown on the voting form, or via the Internet at the web site shown on the voting form. A proxy card or a voting instruction card from the 401(k) Plan Trustee may be voted only by mail or by telephone. Votes submitted via the Internet or by telephone must be received by 11:59 p.m., Eastern Standard Time, on May 14, 2003. Votes submitted to the 401(k) Plan Trustee must be received by May 12, 2003. Voting by returning a paper proxy, via the Internet or by telephone will not affect your right to vote in person should you decide to attend the Annual Meeting. However, if your shares are held through a bank, broker or the 401(k) Plan and you wish to vote those shares in person at the Annual Meeting, you must in advance of the Annual Meeting, obtain a legal proxy from your bank, broker or the 401(k) Plan Trustee. How do proxies work? Sallie Mae's Board of Directors is requesting your proxy. Giving the Board your proxy means that you authorize representatives of the Board to vote your shares at the Annual Meeting in the manner you specify. If you sign and return the enclosed proxy card or voting instruction form but do not specify how to vote, the Board of Directors will vote your shares in favor of all of the director nominees named in this proxy statement, amendment of the Certificate of Incorporation and ratification of PricewaterhouseCoopers LLP, as independent auditor. Giving the Board your proxy also means that you authorize their representatives to vote on any other matter presented at the Annual Meeting in such manner 1

as they determine best. The Corporation does not know of any other matters to be presented at the Annual Meeting as of the date of this proxy statement. If you own shares through the 401(k) Plan, however, and do not vote your plan shares, the Trustee will vote your plan shares in the same proportion as other plan shares have been voted. Can I change my vote? A shareholder whose ownership is recorded directly has the power to change or revoke a proxy prior to its exercise by voting in person at the Annual Meeting, by giving written notice to the Corporate Secretary or by giving a later dated proxy prior to the meeting. A shareholder whose shares are owned beneficially through a bank, broker, or the 401(k) Plan must contact that entity to change or revoke a previously given proxy. CORPORATE PERFORMANCE The Corporation's annual report to shareholders for 2002 is included in the mailing with this proxy statement and Form 10-K. We urge you to read it carefully. The following graph compares the yearly percentage change in the Corporation's cumulative total shareholder return on its common stock to that of Standard & Poor's 500 Stock Index and Standard & Poor's 500 Diversified Financial Services Index. The graph assumes a base investment of $100 at December 31, 1997 and reinvestment of dividends through December 31, 2002.

STOCK OWNERSHIP Sallie Mae encourages stock ownership by its directors, officers and employees to align their interests with those of shareholders. We believe this policy sharply focuses directors and the workforce on economic performance and long-term strategic initiatives that will enhance shareholder returns. To support our ownership policy, the Corporation: o compensates non-employee directors only in the form of options on the Corporation's common stock; o requires that a portion of any annual bonus paid to any officer be in the form of Sallie Mae stock; o grants stock options to all employees; and o established a share ownership policy for senior officers, which is explained in the Executive Compensation section of this proxy statement. In order to reinforce the importance of sustained, long-term shareholder returns, some of these arrangements have share ownership retention requirements or incentives. The following table provides information regarding shares owned by each director and nominee to the Board of Directors and for each executive officer of the Corporation named in the Summary Compensation Table in this proxy statement at February 28, 2003.

Mr. Fox and Mr. Hunt were formerly officers of the GSE longer than 10 years ago. There are no family relationships among the nominees and the executive officers of the Corporation. During 2002, Thomas J. Fitzpatrick, III, a son of Mr. Fitzpatrick, was employed by a Corporation subsidiary as an educational account executive and received a base salary of $30,000 and commissions of $77,422 totaling $107,422 for his services during the year. Director Compensation Since 1997, the Board of Directors has been compensated solely in the form of options granted on the Corporation's common stock. The Board believes that an all-equity compensation plan, which includes significant stock ownership, best aligns director and shareholder interests. In January 2003, for service in 2003, Mr. Fox, as Chairman, received an option grant covering 12,750 shares of the Corporation's common stock, Mr. Porter, as the lead independent director, received an option grant covering 10,625 shares, and other non-employee directors received an option grant covering 8,500 shares. These options vest upon the later of: 1) the Corporation's common stock reaching a closing price of $126.72 (a 20 percent increase over the grant price--the fair market value on the date of grant of $105.60 per share) for five trading days; or 2) separation from service from the Board, whichever occurs first. The options also vest on the fifth anniversary of their grant date. The options are forfeited if the optionee is not elected to the Board at the May 15, 2003 meeting. Directors are eligible to receive replacement options upon the exercise of vested options for options granted through 2002. Options granted in 2003 are not eligible for replacement options. Replacement options are explained in the Executive Compensation section of this proxy statement. In 2002, this program resulted in options covering 13,166 options being granted to Mr. Daley; 7,972 options being granted to Mr. Diefenderfer; 19,515 options being granted to Mr. Fox; 28,903 options being granted to Mr. Hunt; 29,903 options being granted to Dr. Lambert; 16,227 options being granted to Dr. Munitz; and 53,047 options being granted to Mr. Schoellkopf. Directors are eligible to participate in the Corporation's matching gift program. Under the matching gift program the Corporation contributes three dollars for each dollar contributed by a director to post-secondary educational institutions, up to a total contribution by the Corporation of $100,000 per year. The Corporation contributes two dollars for each dollar contributed to a primary or secondary educational institution, a civic, community, health or human service organization, up to a total contribution by the Corporation of $25,000 per year. The Corporation contributes one dollar for each dollar contributed to an arts or cultural organization, the United Way, or a federated campaign, up to a total contribution by the Corporation of $10,000 per year. Notwithstanding the above limits for each category, aggregate matching contributions by the Corporation are limited to $100,000 per director in any single plan year. The Corporation's non-employee directors are provided with $50,000 of life insurance, are reimbursed for their and their spouses' expenses incurred in connection with attending Board meetings, are covered by a travel insurance plan 8

while traveling on corporate business and may receive a $1,500 per diem payment for additional work. No such payments were made to directors in 2002. Mr. Lord and Mr. Fitzpatrick are eligible for the director's matching gift program described above. Neither Mr. Lord nor Mr. Fitzpatrick received any other separate compensation for their service on the Board in 2002. Neither Mr. Lord nor Mr. Fitzpatrick were recipients of the 2003 option grants described above. Non-employee directors who serve on the Board of the GSE are separately compensated for that service. Mr. Diefenderfer and Mr. Hunt each were compensated $10,000 and Ms. Gilleland was compensated $6,000 for attending GSE Board meetings in 2002. EXECUTIVE COMPENSATION This section includes (1) a report by the Compensation and Personnel Committee (the "Compensation Committee" or "Committee") regarding the Corporation's executive compensation policy; (2) a summary presentation of 2002 executive compensation in tabular form; (3) a summary of 2002 stock option grants to Named Executive Officers; (4) a valuation of option exercises during the year and remaining option holdings for Named Executive Officers; and (5) descriptions of pension plan benefits, certain employment arrangements and related transactions. Report of the Compensation and Personnel Committee on Executive Compensation The Compensation Committee of the Board of Directors develops a comprehensive compensation policy for senior management and establishes plans and programs to implement the policy. The Committee annually reviews the performance of the CEO and senior management team and, after consultation with the Board, establishes compensation terms for these individuals. The Committee utilizes the services of an independent compensation consulting firm in establishing both executive and director compensation. No member of the Committee is a former or current officer or employee of the Corporation or any of its subsidiaries, and all Committee members are independent, as defined in the Corporation's By-laws. Compensation Policy. The Corporation's executive compensation policy is based on a belief that compensation that promotes long-term management stock ownership and is tied to corporate performance and sustained share price will enhance shareholder value. To implement this policy, the Committee strives to strike a balance between fixed compensation in the form of base salary, and "at risk" compensation, in the forms of annual bonuses based on the attainment of corporate and individual goals, and longer-term, stock-based awards. A goal of the Committee is to offer a total compensation potential that is competitive with that offered at peer companies. The Committee believes that the Corporation's most direct competitors for executive talent are not necessarily the companies that would be included in a peer group of similarly sized financial services companies established to compare shareholder returns. Thus, the compensation peer group is not the same as the peer group index in the Comparison of Five Year Cumulative Total Return graph included in this proxy statement. The peer group for compensation purposes includes banks, transaction processing institutions, insurance companies and other GSEs with workforce size, revenues, assets and market value within a range above and below the Corporation's levels. The group is reviewed annually and changes are made as appropriate to reflect changes in the industry, such as mergers and acquisitions. The total compensation package at the Corporation is designed to attract and to retain executive officers who are entrepreneurial and desire a "risk and reward" compensation structure that is based on ownership and performance principles. To further promote the principle of executives as owners, the Corporation adopted stock ownership guidelines in January 1999. Ownership levels, which are expected to be achieved over a three-year period, are: Stock Ownership as a Position Multiple of Base Salary -------- ----------------------- CEO 10 x salary President 10 x salary Executive Vice President 10 x salary Senior Vice President 7 x salary Unvested performance stock and unexercised options, whether vested or not, are not counted in calculating stock ownership. As of February 28, 2003, 17 of the Corporation's 19 senior officers, including all of the officers who have been with the Corporation three years or more, have achieved compliance with their ownership guidelines. 9

Employment Agreements. In January 2002, the Corporation entered into executive employment agreements with Messrs. Lord and Fitzpatrick. These agreements are designed to promote our long-term performance and succession planning goals and are summarized in the Employment Agreement section of this proxy, beginning on page 15. Base Salary. In establishing salaries, the Committee reviewed the salaries of executives at peer companies in positions that the Committee considered to be comparable to their particular executive position. Messrs. Lord and Fitzpatrick's base salaries for 2002 were fixed in their employment agreements and did not increase from 2001. Mr. Lord's base salary was significantly below the 25th lowest percentile for salaries paid to chief executive officers at the Corporation's peer companies. Mr. Fitzpatrick's base salary for 2002 was significantly below the 50th percentile. Base salaries for other senior officers did not increase from 2001 to 2002, as well, and their salaries remained below the 25th percentile. Accordingly, a significant portion of each executive officer's cash compensation is subject to the achievement of goals as set forth in the Corporation's annual performance bonus program. Performance Bonuses. The Compensation Committee believes that executive officer annual bonuses should be tied to satisfaction of specified performance criteria. For 2002, the Compensation Committee established a bonus program under the shareholder-approved Management Incentive Plan, under which bonuses could be earned based on corporate performance and individual performance. The terms of the program establish the maximum bonus amount that may be earned in any one year. The Committee may use its discretion to reduce payments below that amount. The corporate performance goals were set by the Committee in January 2002, after consideration by the Board of the 2002 business plan. The goals, which were set as "stretch" targets and were directly related to key components of the 2002 business plan, involved specific levels of: "core cash" earnings per share growth; fee income growth; preferred channel loan origination growth; and operating expense control. ("Core cash" earnings are defined in the Corporation's annual report to shareholders). The corporate goals were communicated to all officers during the first quarter of 2002, and status reports of corporate achievement towards the goals were provided throughout the year to both the Committee and the officer group. The Corporation's performance exceeded the earnings per share growth and expense control targets, but failed to achieve the other two stretch targets. Bonus payouts reflected this overall corporate performance, as well as an officer's individual achievements. Mr. Lord's individual performance was evaluated by the Committee in consultation with the full Board. Among the factors considered by the Committee in awarding Mr. Lord's individual performance-based bonus were: control of operating costs; solid growth in the student loan portion of the business, including effective implementation of a loan consolidation strategy; new business development, primarily in the areas of debt collection and consumer lending; and the Corporation's funding strategy and capital management, particularly with regard to the acceleration of the pace of the "wind-down" of the Student Loan Marketing Association. The Compensation Committee approved other executive officer performance bonuses, as recommended by Mr. Lord, based on their individual performance and on relative compensation levels within the executive officer ranks. Consistent with the Compensation Committee's preference for equity-oriented compensation, a minimum of 40 percent of each executive officer's annual bonus was awarded in the form of Sallie Mae common stock. Stock Options and Stock-Based Compensation. Since 1997, a centerpiece of the Corporation's compensation program for all employees has been stock-based compensation. The Compensation Committee believes that stock options and various forms of restricted stock provide an appropriate incentive to promote long-term stable growth while aligning employees' interests with those of shareholders. The Committee also believes that the Corporation's strong, sustained share performance is attributable to this important component of its compensation program. In January 2002, the Compensation Committee granted options to Messrs. Lord and Fitzpatrick under the terms of their employment agreements. Other members of the senior management team were granted options, as well. Awards made to Named Executive Officers are disclosed in the 2002 Option Grant Table on page 13 of this proxy statement. In January 2003, the Committee determined to significantly reduce option awards to senior management, and in some cases, eliminate them altogether (other than the commitments made to Messrs. Lord and Fitzpatrick under their employment agreements), in consideration of shareholder dilution concerns and share ownership positions of the senior management team as a whole, which have achieved a level that the Committee believes effectively links their interests with that of shareholders. A description of the options granted to Messrs. Lord and Fitzpatrick is included in the Employment Agreement section of this proxy on page 15. Options granted in 2002 to others in senior management vest upon the stock price reaching 120 percent of the grant price, but no earlier than 12 months from their grant date. These options also vest on the eighth anniversary of their grant date, or upon a change in control of the Corporation. If options vest upon a change in control and, as a result, an executive becomes subject to excise taxes, the Corporation will make certain tax gross-up payments on behalf of the executive. 10

In 1999, the Corporation established a replacement option program to assist executive officers in meeting their share ownership targets. The program also applies to Board members. Under the replacement program, officers and directors have been eligible to receive new options upon their exercise of vested options in an amount equal to the number of shares needed to pay the exercise price for the original option. Replacement options carry an exercise price equal to the fair market value of the Corporation's common stock on the date of their grant and vest one year from the grant date. The term of replacement options equals the remaining term of the underlying options. The options granted to Messrs. Lord and Fitzpatrick in 2002 are not eligible for "replacement options." Further, the Committee determined that, with the exception of newly hired or promoted officers, options granted to other officers in 2003 would not be eligible for replacement options. Perquisites. The Committee undertook a review of executive perquisites and, in particular, examined the personal use by executives of company-owned or leased property, the use of sports tickets and private club memberships. The Committee determined that perquisites provided to executives are few and appropriate; the personal use of company-owned or leased property by executives is insignificant; and the Corporation complied with its policy with respect to personal use of company-owned or leased property, in that executives reimbursed the Corporation for such use or included the value of such use in taxable compensation. Section 162(m). Section 162(m) of the Internal Revenue Code limits to $1 million the deductibility of compensation paid to each of the Corporation's five Named Executive Officers, unless the compensation satisfies one of the exceptions set forth in the Code, which includes an exception for "performance-based compensation." The Compensation Committee generally attempts to have significant aspects of performance-based compensation that it awards qualify under Section 162(m), although it recognizes that situations may arise where other considerations may prevail over obtaining such qualification. The Compensation Committee believes that the compensation the Corporation's Named Executive Officers received in 2002 will not be subject to the $1 million limitation.

At least 40 percent of bonuses are paid in SLM common stock. (2) Employer matching contributions under the Sallie Mae 401(k) Savings Plan and the Sallie Mae Supplemental 401(k) Savings Plan. (3) Amounts are the market value of 50,000 shares granted on January 24, 2002 and 25,000 shares granted on January 25, 2001 as restricted stock units (RSUs). The RSUs granted in 2002 were granted under Mr. Lord's employment agreement and vest on December 31, 2004. If vested, these RSUs are converted into stock in the year following Mr. Lord's termination from the Corporation as CEO. The RSUs granted in 2001 are compensation for service successfully performed in 2000; however, the Compensation Committee placed restrictions on the RSUs as a retention tool. All of the RSUs were forfeitable by Mr. Lord if he voluntarily left employment prior to January 25, 2002, and one-half of the RSUs were forfeitable if Mr. Lord voluntarily left employment on or after January 25, 2002, but prior to January 25, 2003. The value of all unvested RSUs as of December 31, 2002 was $6,491,250. (4) Includes options granted under the replacement option program. (5) Amounts are the market value of 50,000 shares granted as RSUs on January 24, 2002, 3,976 shares granted on January 25, 2001, and 2,727 shares granted on January 27, 2000. The RSUs granted in 2002 were granted under Mr. Fitzpatrick's employment agreement and vest on December 31, 2006. If vested, these RSUs are converted into stock in the year following Mr. Fitzpatrick termination from the Corporation. The shares granted in 2001 and 2000 were forfeitable if: 1) Mr. Fitzpatrick failed to invest 100% of the annual bonus to which the award relates in Sallie Mae stock for 12 months, or 2) Mr. Fitzpatrick voluntarily terminated his employment during this 12-month period. The amount reported for 2000 also includes the market value of 50,000 shares of performance stock granted on July 31, 2000, which have vested or will vest upon the achievement of corporate performance goals. As of December 31, 2002, a total of 57,802 shares of all the shares reported in this column remained unvested with a market value of $6,003,315. 12

(6) Amount is the market value of 10,000 shares of performance stock granted on January 1, 2001. As of December 31, 2002, 1,200 shares remained unvested with a market value of $124,632. Perquisites provided were less than $50,000. Perquisites included a medical insurance benefit of $3,000, a financial planning benefit of $4,000, and reimbursement for spouses' travel expenses incurred in connection with attending Board meetings. 2002 Option Grant Table Number of Securities Underlying % of Total Options Granted Exercise Options --------------- Price Granted to Grant Date Grant Expiration And Market Employees in Present Value Name Initial Replacement Date Date Price On Fiscal Year ------------- - ---- ------- ----------- ---- ---- Grant Date ----------- ---------- Albert L.

Option vesting terms for "initial" option grants to Messrs. Lord and Fitzpatrick are described in the Employment Agreement section on page 15. For options granted to other Named Executive Officers, options vest upon the stock price reaching 120 percent of the grant price for five trading days, but no earlier than 12 months from their grant date. The options also vest on the eighth anniversary of their grant date or upon a change in control of the Corporation. If options vest upon a change in control and, as a result, an executive becomes subject to excise taxes, the Corporation will make certain gross-up payments on behalf of the executive. Replacement options vest one year from their grant date. Except in the event of death, disability or involuntary termination due to job abolishment, option vesting is contingent upon continued employment through the vesting date. 13

This entitled the Named Executive Officers to grants of replacement options and enabled them to increase their stock ownership positions, consistent with corporate objectives. The table above sets forth information on the number and the value of exercisable and unexercisable stock options held by the Named Executive Officers as of the fiscal year-end, calculated by the difference between the Corporation's fiscal year-end stock price, $103.86, and the option's exercise price.

Under the formula, each participant has an account, for record keeping purposes only, to which credits are allocated each payroll period based on a percentage of the participant's compensation for the current pay period. The applicable percentage is determined by the number of years of service the participant has with the Corporation. If an individual participated in the Corporation's prior pension plan as of September 30, 1999 and met certain age and service criteria, the participant ("grandfathered participant") will receive the greater of the benefits calculated under the prior plan, which uses a final average compensation formula, or under the cash balance formula. Mr. Lord, Mr. Levine, and Ms. Keler qualify as grandfathered participants. Through December 31, 2005, Ms. McCormack's benefit accrues under a formula grandfathered in connection with the Corporation's acquisition of USA Group that takes into account compensation and age. The Corporation's supplemental pension plan assures that designated participants receive the full amount of benefits to which they would have been entitled under the pension plan but for limits on compensation and benefit levels imposed 14

by the Internal Revenue Code. For grandfathered participants, the amount of compensation considered for the prior supplemental pension plan is the sum of the individual's salary and annual bonus, up to 35% of the prior year's salary. For all participants in the supplemental cash balance plan (effective October 1, 1999), the amount of compensation is the sum of salary and annual bonus. The previous table illustrates the approximate annual pension that may be payable to an employee in the higher salary classifications under the Corporation's prior final average compensation plans, at age 62, as a single life annuity. The benefit amounts shown are not subject to any deductions for Social Security or other plan benefits. The credited years of service as of December 31, 2002 for Mr. Lord is 17 years, 9 months; Mr. Fitzpatrick is 4 years, 4 months; Ms. Keler is 18 years, 0 months; Mr. Levine is 21 years, 10 months; and Ms. McCormack is 16 years, 9 months (includes service with USA Group). The projected annual benefit payable upon retirement at age 62 under the new cash balance plans for each of these individuals is: Mr. Lord - $420,000; Mr. Fitzpatrick - $142,000; Ms. Keler - $245,000; Mr. Levine - $294,000; and Ms. McCormack - $104,000. Mr. Fitzpatrick is entitled to additional retirement payments under his employment agreement. Employment Agreements In January 2002, the Corporation entered into employment agreements with Messrs. Lord and Fitzpatrick to secure their commitment to continued employment with the Corporation. The terms of the agreements are consistent with the Corporation's emphasis on "at risk" executive compensation, in that the parties intend that current base salary and the parameters for annual cash bonuses will not be changed during the term of the agreements and the potential value of long-term incentives for the executives is tied to increases in the Corporation's share price. In addition, to retain the executives' service and promote their focus on sustained increases in the Corporation's share price, the agreements defer the executives' ability to realize the benefit of certain stock-based awards in some cases beyond the term of their employment, notwithstanding that the awards may vest earlier. The term of Mr. Lord's agreement is the three-year period ending December 31, 2004, subject to a one-year extension unless either Mr. Lord or the Board elect not to extend the term. Under the agreement, Mr. Lord received 1,000,000 stock options in January 2002 (the "2002 Options") and received 500,000 options in January 2003 (the "2003 Options"). The options are exercisable after price-vesting, and time-vesting targets are met in any case on and after January 1, 2010 for the 2002 Options and January 1, 2011 for the 2003 Options. For each one-third of an option grant, the price-vesting targets are a set percentage increase over the fair market value of the options on the date of grant. The percentage targets are a 25 percent increase, a 33 percent increase and a 50 percent increase, respectively, and must be sustained for five consecutive trading days. For the 2002 Options, the price-vesting targets are: $107.50; $114.38; and $129.00, and for the 2003 Options, the price-vesting targets are $132.00; $140.45; and $158.40. The earliest vesting date for the 2002 Options is June 1, 2005, and for the 2003 Options, January 1, 2006. To the extent not forfeited or exercised, the options expire on the tenth anniversary of their grant date. The options are not eligible for the Corporation's replacement option program. Mr. Lord also received 50,000 restricted stock units in January 2002 and 50,000 restricted stock units in January 2003. Both sets of restricted stock units vest on December 31, 2004, and delivery of the vested shares is deferred until retirement or termination of employment. If Mr. Lord's employment is terminated by the Corporation without cause, or by Mr. Lord for good reason, the vesting of the options and restricted stock units is accelerated, and Mr. Lord will receive a cash payment equal to his salary and three-year average annual bonus multiplied by the lesser of three or the number of years remaining in the term of the agreement. If his termination under either of these conditions follows within 24 months of a change in control, Mr. Lord will receive a cash payment equal to three times salary and three-year average annual bonus. If any change in control occurs, regardless of whether a termination of employment occurs, Mr. Lord's unvested stock options and restricted stock units vest. Change in control payments are subject to being grossed-up for any excise taxes payable by Mr. Lord and for taxes payable on the grossed-up amounts. The agreement with Mr. Fitzpatrick is for the five-year period ending December 31, 2006. Under the agreement, Mr. Fitzpatrick received 600,000 options in 2002 (the "2002 Options") and 300,000 options in January 2003 (the "2003 Options"). The terms and conditions of the options granted or to be granted to Mr. Fitzpatrick are generally the same as those granted or to be granted to Mr. Lord. Mr. Fitzpatrick also received 50,000 restricted stock units in January 2002, 50,000 units in January 2003, and subject to continued employment will receive 50,000 units in January 2004. All units vest on December 31, 2006, and delivery of the vested shares is deferred until retirement or termination of employment. Provisions regarding acceleration of vesting and delivery of shares subject to restricted stock units, acceleration of exercisability of options, termination of employment payments and change in control payments that apply to Mr. Lord also generally apply to Mr. Fitzpatrick. An additional acceleration event applies in the event Mr. Lord leaves as chief executive officer and Mr. Fitzpatrick is not selected to succeed Mr. Lord as chief executive officer. Mr. Fitzpatrick is also entitled to a supplemental retirement payment, which generally assures him of an annual benefit of $250,000 if he works 15

continuously for the Corporation through age 60. This payment is offset by any amounts paid under the Corporation's pension plan program. The applicable agreements provide that Messrs. Lord and Fitzpatrick will not compete with the Corporation or its affiliates for a period of at least two years following termination of employment for any reason. The agreements provide that Messrs. Lord and Fitzpatrick will be nominated for Board service for the terms of their agreements. Also, the Corporation assumed Ms. McCormack's employment agreement, as amended, upon the Corporation's acquisition of USA Group in July 2000. The agreement with Ms. McCormack ends on August 1, 2003. The agreement entitles her to a minimum annual base salary of $225,000, and grants of 120,000 options covering the Corporation's common stock and 60,000 shares of performance stock. The options vested on June 14, 2001, 12 months after the grant date and after achievement of price-vesting targets. The performance stock vests upon the achievement of expense and revenue targets. If Ms. McCormack's employment is terminated by the Corporation without cause or by Ms. McCormack for cause, as those terms are defined in the agreement, Ms. McCormack is entitled to receive a payment equal to twice her annual base salary. Indebtedness No loans were outstanding to any executive officers or directors during 2002.

The primary purpose of this proposal is to enable the Corporation to effect potential future stock splits and stock dividends as well as for general corporate purposes described below. The proposed amendment would increase the number of authorized shares of common stock from 375,000,000 shares to 1,125,000,000 shares. The text of the first sentence of Article 4 of the Charter, as it is proposed to be amended, is as follows: The total number of shares of stock which the Corporation shall have authority to issue is 1,145,000,000 shares of capital stock, consisting of (i) 1,125,000,000 shares of common stock, par value $.20 per share (the "Common Stock"), and (ii) 20,000,000 shares of preferred stock, par value $.20 per share (the "Preferred Stock"). As of March 17, 2003, 151,641,590 shares were issued and outstanding out of the currently authorized 375,000,000 shares and, after taking into account shares reserved for issuance upon the exercise of the Corporation's stock options and warrants, and shares reserved for equity forward transactions to achieve favorable accounting treatment, approximately 134,566,425 shares of common stock were available for issuance. An increase in the amount of common stock authorized by the Corporation's Charter is necessary for the Corporation to declare a three-for-one stock split and it is the intention of the Board of Directors to take that action if this amendment is approved. This planned stock split would be effected as a dividend of 2 shares. Without approval of the proposed amendment to the Corporation's Charter, the Corporation would not have sufficient authorized capital to declare a stock split in the form of a dividend of 2 shares. Generally, stock splits are intended to shift the market price range of common stock to a level that will facilitate increased trading activity and will broaden the marketability of common stock. Approval of the proposed amendment will allow the Corporation to declare a corresponding stock split in the form of a stock dividend while maintaining the current ratio of issued-to-authorized shares of common stock, thereby maintaining the same flexibility that currently exists for the Corporation to use capital stock for future business and financial purposes. Authorized but unissued shares of common stock may be used by the Corporation for any purpose permitted under Delaware law, including to raise capital, to provide equity incentives to employees and directors and to enter into strategic transactions that the Board of Directors believes provide the potential for growth and profit. Authorized but unissued shares of common stock may also be used to oppose a hostile takeover attempt or to delay or prevent a change in control of the Corporation, although the Corporation has no present intention to issue shares for such purpose. The proposed amendment has been prompted by business and financial considerations, and the Corporation is not aware of any threat of takeover or change in control. 17

Under the proposed amendment, each of the newly authorized shares of common stock will have the same rights and privileges as currently authorized common stock. Adoption of the proposed amendment will not affect the rights of the holders of currently outstanding common stock of the Corporation nor will it change the par value of the common stock. The last increase in the number of authorized shares of common stock was approved by stockholders in 2001. The proposed amendment to increase the authorized number of shares of common stock does not change the number of shares of preferred stock that the Corporation is authorized to issue. The Corporation's last stock dividend was in 1998, with a seven-for-two split of the Corporation's common stock. If the proposed amendment is adopted, it will become effective upon filing a Certificate of Amendment to the Corporation's Charter with the Secretary of State of the State of Delaware. However, if shareholders approve the proposed amendment to the Corporation's Charter, the Board of Directors retains the discretion under Delaware law to abandon and not implement the proposed amendment to the Charter (and the proposed stock split) and the number of authorized shares would accordingly remain at current levels. The Corporation has been advised by tax counsel that a split in the form of a stock dividend would result in no gain or loss or realization of taxable income to the holders of common stock under existing federal tax law. Non-U.S. stockholders should consult with their financial advisors regarding tax treatment in other jurisdictions. Required Vote The affirmative vote of the holders of a majority of the shares of common stock of the Corporation outstanding on March 17, 2003 is required to amend the Charter. Unless marked to the contrary, proxies received will be voted FOR the amendment to the Corporation's certificate of incorporation. Board Recommendation The Board of Directors of the Corporation recommends a vote FOR approval to amend the Charter. REPORT OF THE AUDIT COMMITTEE The Audit Committee has reviewed and discussed with management and the Corporation's independent auditors, PricewaterhouseCoopers LLP, the Corporation's audited financial statements as of and for the year ended December 31, 2002. The Committee also discussed with PricewaterhouseCoopers LLP, the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended, by the Auditing Standards Board of the American Institute of Certified Public Accountants, and with and without management present, discussed and reviewed the results of the independent auditors' examination of the financial statements. The Committee received and reviewed the written disclosures and the letter from the independent auditors required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees, as amended, and has discussed with the auditors the auditors' independence. The Committee discussed with PricewaterhouseCoopers LLP relationships that may have an impact on their objectivity and independence. The Committee considered whether the provision of non-financial audit services was compatible with PricewaterhouseCoopers LLP's independence in performing financial audit services. Following the reviews and discussions referred to above, the Committee recommended to the Board of Directors that the financial statements referred to above be included in the Corporation's Annual Report on Form 10-K for the year ended December 31, 2002. Audit Committee Ann Torre Grant, Chairman Barry L. Williams, Vice Chairman Charles L. Daley Ronald F. Hunt A. Alexander Porter, Jr. Steven L. Shapiro 18

PROPOSAL 3--APPOINTMENT OF INDEPENDENT AUDITOR The Corporation's independent financial auditor is selected by the Audit Committee. On January 28, 2003, the Audit Committee appointed PricewaterhouseCoopers LLP as the Corporation's independent financial auditor for 2003, subject to ratification by the Corporation's shareholders. PricewaterhouseCoopers LLP has served as auditor for the Corporation since May 16, 2002. This proposal is put before the shareholders because the Board believes that it is a good corporate practice to seek shareholder ratification of the selection of the independent financial auditor. If the appointment of PricewaterhouseCoopers LLP is not ratified, the Audit Committee will evaluate the basis for the shareholders' vote when determining whether to continue the firm's engagement. Representatives of PricewaterhouseCoopers LLP are expected to attend the Annual Meeting and to respond to appropriate questions from shareholders present at the meeting, and will have an opportunity to make a statement if they desire to do so. Principal Accountant Fees and Services Aggregate fees for professional services rendered for the Corporation by PricewaterhouseCoopers LLP and Arthur Andersen LLP as of and for the years ended December 31, 2002 and 2001, respectively, were: 2002 2001 Audit $2,653,612 $1,950,866 Audit Related 2,170,878 935,942 Tax 1,530,840 3,278,169 All Other 481,891 1,990,930 ---------- ---------- Total $6,837,221 $8,155,907 ========== ========== The Audit Fees were for professional services rendered for the audits of the consolidated financial statements of the Corporation and statutory and subsidiary audits, issuance of comfort letters, consents, income tax provision procedures, and assistance with review of documents filed with the SEC.

In addition, the Corporation has not been notified of any other business that is proposed to be presented at the Annual Meeting. If other matters now unknown to the Board come before the Annual Meeting, the accompanying proxy card confers discretionary authority on the persons named on the proxy card to vote such proxies on any such matters in accordance with their best judgment. Solicitation Costs All expenses in connection with the solicitation of the enclosed proxy will be paid by the Corporation. In addition to solicitation by mail, officers, directors, regular employees or other agents of the Corporation may solicit proxies by telephone, telefax, personal calls, or other electronic means. The Corporation will request banks, brokers, custodians and other nominees in whose names shares are registered to furnish to beneficial owners of the Corporation's common stock material related to the Annual Meeting, including the annual report, this proxy statement and the proxy card to the beneficial owners of such shares and, upon request, the Corporation will reimburse such registered holders for their out-of-pocket and reasonable expenses in connection therewith. Shareholder Proposals for 2004 Annual Meeting A shareholder who intends to introduce a proposal for consideration at the Corporation's year 2004 Annual Meeting, set for May 13, 2004, may seek to have that proposal and a statement in support of the proposal included in the Corporation's proxy statement if the proposal relates to a subject that is permitted under U.S. Securities and Exchange Commission ("SEC") Rule 14a-8. To qualify for this, the shareholder must submit the proposal and supporting statement to the Corporation not later than December 8, 2003 and must satisfy the other requirements of Rule 14a-8. The submission of a shareholder proposal does not guarantee that it will be included in the Corporation's proxy statement. A shareholder may otherwise propose business for consideration or nominate persons for election to the Board of Directors, in compliance with federal proxy rules, applicable state law and other legal requirements and without seeking to have the proposal included in the Corporation's proxy statement pursuant to Rule 14a-8. The Corporation's By-laws provide that any such proposals or nominations for the Corporation's 2004 Annual Meeting must be received by the Corporation after February 15, 2004 and on or before April 15, 2004. Any such notice must satisfy the other requirements with respect to such proposals and nominations contained in the Corporation's By-laws. If a shareholder fails to meet these deadlines or fails to comply with the requirements of SEC Rule 14a-4, the Corporation may exercise discretionary voting authority under proxies it solicits to vote on any such proposal. Section 16(a) Beneficial Ownership Reporting Compliance Section 16 of the Securities Exchange Act of 1934 requires the Corporation's executive officers and directors to file reports on their holdings of and transactions in the Corporation's common stock. To the Corporation's knowledge, for the fiscal year 2002 all of the Corporation's executive officers and directors timely filed all required reports under Section 16, except Mr. Diefenderfer and Mr. Hunt each failed to timely file a report on a routine benefit plan purchase transaction of 19 shares over which neither individual had control. Householding The SEC recently approved a rule concerning the delivery of annual reports and proxy statements. It permits a single set of these reports to be sent to any household at which two or more shareholders reside if they appear to be members of the same family. Each shareholder continues to receive a separate proxy card. This procedure, referred to as householding, reduces the volume of duplicate information shareholders receive and reduces mailing and printing expenses. A number of brokerage firms have instituted householding. In accordance with a notice sent earlier this year to certain beneficial shareholders who share a single address, only one annual report and proxy statement will be sent to that address unless any shareholder at such an address wishes to receive a separate annual report or proxy statement in the future. A share holder may request a separate copy of such materials by calling toll-free 1-888-810-5988. 21
