2 Forward Looking Statements This Presentation contains forward-looking statements and information based on management's current expectations as of the date of this presentation. Statements that are not historical facts, including, financial projections, statements about our beliefs or expectations and statements that assume or are dependent upon future events, are forward-looking statements. Forward-looking statements are subject to risks, uncertainties, assumptions and other factors that may cause actual results to be materially different from those reflected in such forward-looking statements. These factors include, among others, the occurrence of any event, change or other circumstances that could give rise to our ability to cost-effectively refinance asset-backed financing facilities due April 2010, (collectively, the "2008 Asset-Backed Financing Facilities"), including any potential foreclosure on the student loans under those facilities following their termination; increased financing costs; limited liquidity; any adverse outcomes in any significant litigation to which we are a party; our derivative counterparties terminating their positions with the Company if permitted by their contracts and the Company substantially incurring additional costs to replace any terminated positions; changes in the terms of student loans and the educational credit marketplace (including changes resulting from new laws, such as any laws enacted to implement the Administration's 2010 budget proposals as they relate to the Federal Family Education Loan Program ("FFELP") and regulations and from the implementation of applicable laws and regulations) which, among other things, may change the volume, average term and yields on student loans under the FFELP, may result in loans being originated or refinanced under non-FFELP programs, or may affect the terms upon which banks and others agree to sell FFELP loans to the Company. The Company could be affected by: various liquidity programs being implemented by the federal government; changes in the demand for educational financing or in financing preferences of lenders, educational institutions, students and their families; incorrect estimates or assumptions by management in connection with the preparation of our consolidated financial statements; changes in the composition and performance of our Managed FFELP and Private Education Loan portfolios; changes in the general interest rate environment, including the rate relationships among relevant money-market instruments, and in the securitization markets for education loans, which may increase the costs or limit the availability of financings necessary to initiate, purchase or carry education loans; changes in projections of losses from loan defaults; changes in general economic conditions; changes in prepayment rates and credit spreads; and changes in the demand for debt management services and new laws or changes in existing laws that govern debt management services. All forward-looking statements contained in this Presentation are qualified by these cautionary statements and are made only as of the date of this Presentation. The Company does not undertake any obligation to update or revise these forward-looking statements to conform the statement to actual results or changes in the Company's expectations. "Core Earnings" Performance Measures - The following presentation includes "Core Earnings" performance measures. A presentation of the most comparable GAAP financial measures and a reconciliation of the "Core Earnings" performance measures to the most directly comparable GAAP financial measures are included in the our most recent quarterly earnings release, quarterly earnings report on Form 10-Q and annual report on Form 10-K, which are available on our website at (http://www2.salliemae.com/investors/stockholderinfo/earningsinfo) and (http://www2.salliemae.com/investors/stockholderinfo/secfilings) and on the SEC's website (http://www.sec.gov). U.S. Government Guaranteed Student Loans - The following presentation contains references to U.S. Government guaranteed student loans. All such references are to loans made in compliance with the Federal Family Education Loan Program ("FFELP"), under Title IV of the Higher Education Act, to finance educational costs. As more fully described in our most recent quarterly earnings release, quarterly earnings report on Form 10-Q and annual report on Form 10-K, available on our website at (http:// www2.salliemae.com/investors/stockholderinfo/earningsinfo) and (http://www2.salliemae.com/investors/stockholderinfo) and on the SEC's website (http://www.sec.gov), the federal guarantee of FFELP loans is conditioned on loans being originated, disbursed and serviced in accordance with U.S. Department of Education regulations. In addition, unless a loan default results from the borrower's death, disability or bankruptcy, the federal government guarantees no less than 97 percent of the principal balance plus accrued interest and the holder of the loan generally must absorb the two percent (three percent after July 1, 2006) not guaranteed as a loss on the loan ("Risk Sharing"). FFELP loans serviced by a servicer that has an Exceptional Performer designation from the U.S. Department of Education are not subject to Risk Sharing and receive 100% reimbursement on default claims (99 percent reimbursement on default claims filed after July 1, 2006).

67 Rating Actions on SLM Private Credit Student Loan ABS There have been a number of upgrades and no downgrades to Sallie Mae's Private Credit ABS since the program's inception in 2002 Moody's(1) - March 2007 S&P - July 2008 Fitch - September 2007 On September 17, 2008, as a result of Lehman's bankruptcy and rating downgrade, Moody's placed all of the tranches from the SLM Student Loan Trust 2004-1 transaction on review for possible downgrade. Lehman Brothers Special Financing Inc. acted as interest rate swap provider for the class A-6 reset rate notes. The Lehman interest rate swap expires in January 2009 and is fully cash collateralized.

68 Private Credit Loan Collections Sallie Mae services and collects the loans in its Private Credit ABS Trusts Private credit collections are conducted by a stand-alone consumer credit collections unit, not the company's FFELP collections operations Managed by individuals with prior experience managing collections operations for consumer loan assets Over the past 18 months, private credit collections resources have been significantly increased and collections technology and practices enhanced Multi-variable analysis has enabled prioritization of collection efforts on higher risk borrowers Forbearance policies have been enhanced to reduce reliance on the tool, while still meeting the customer need during an economic downturn Additional workout and settlement programs have been introduced to help customers avoid default Collection workstation, dialer capabilities, and internet utilities have all been enhanced with more effective technology solutions

69 Forbearance A collections tool used to provide borrowers time to improve their ability to repay Between graduation and start of first job Economic hardship Provides borrower with time to obtain employment and income to support their obligations Applied most frequently in the first two years of repayment Granted for three month intervals, up to a maximum of 24 months Majority of loans are in forbearance for less than 12 months Placing a loan in forbearance suspends payments, with interest capitalized to the loan balance

70 SLM Private Credit Delinquency and Forbearance Seasoning Trends Delinquency and forbearance are highest when loans enter repayment, and diminish as loans season As the trust loans season, delinquency and forbearance are expected to decline Note: Based on historical data through March 31, 2009

Prior to November 1, 2008, the servicer exercised this repurchase option and actual charge-offs in these trusts equaled zero. Beginning November 1, 2008, the servicer ceased purchasing from the trust loans that are more than 180 days delinquent. For the purposes of comparison across all deals, this chart reflects trust charge-offs for SLM Private Credit Student Loan Trusts issued prior to 2005-B as if the servicer had never exercised its repurchase option.
