2 THE COMMITTEE TO RESTORE VALUE AT SALLIE MAE 1317 F Street, N.W., Suite 202 Washington, D.C. 20004 (202) 879-2060 July 24, 1997 Dear Sallie Mae Shareholder: On this Thursday, July 31, your vote at the Special Meeting of Sallie Mae shareholders will shape the future of your Company. On behalf of The Committee to Restore Value at Sallie Mae (the CRV), we ask that you vote FOR the slate of directors that the CRV has nominated. TO ENSURE THAT YOUR VOTE FOR THE CRV IS COUNTED, PLEASE VOTE TODAY ON THE ENCLOSED GREEN PROXY CARD AND RETURN YOUR PROXY IN THE ENCLOSED OVERNIGHT ENVELOPE. We appreciate the support for the CRV's slate of directors and business plan voiced to date by shareholders and Wall Street analysts. Now, we are pleased to announce that Institutional Shareholder Services, Inc. (ISS), the nation's largest shareholder advisory firm, today recommended that shareholders vote for the CRV's fifteen-member slate of director nominees. In a report to its clients, ISS stated: [W]E FAVOR THE CRV'S STRATEGIC FOCUS, SENSITIVITY TO SHAREHOLDER VALUE, AND CAPABLE MANAGEMENT TEAM OVER CURRENT MANAGEMENT'S 'SHUFFLED BOARD' AND STILL-TO-BE-NAMED CEO. WE RECOMMEND THAT SHAREHOLDERS SUPPORT THE REORGANIZATION PROPOSAL AND THE CRV SLATE USING THE GREEN PROXY CARD.* ISS recognized the CRV's record of creating value for shareholders and the strength of our director nominees and management team. ISS reported, "Because the CRV's initiatives . . . have contributed strongly to driving the company's stock price to record highs, we believe it is wiser to support the CRV than to back an unknown future management team appointed by a relatively new board . . . . We favor selecting a team that has repeatedly devised and promoted strategies that yielded higher earnings and a soaring stock price." ISS continued, "[I]f the want ad for members of a new senior management team requires a track record of creating shareholder value, direct experience in the student loan business, and strategic vision, we think the CRV team is best suited for the task." The CRV's unwavering advocacy of model corporate governance, our growth-oriented business plan and our ownership of over 135,000 shares of Sallie Mae stock demonstrate our commitment to shareholders and to increasing share value. We are proud that our efforts have been endorsed by ISS, a well-respected and independent shareholder advocate. What matters most, however, is your vote! To ensure that your vote for the CRV is counted, please mark, sign, date and return the enclosed GREEN Proxy Card today. Please do not return the Blue proxy card, even as a protest. If you have any questions, you may call our proxy solicitors, MacKenzie Partners, at (800) 322-2885. Further information about voting your shares appears on the back of this letter. Thank you for your support. /s/ EDWARD A. FOX /s/ ALBERT L. LORD EDWARD A. FOX ALBERT L.
