We expect the aggregate proceeds to the Seller to be $2,059,225,958 before deducting expenses payable by the Seller estimated to be $1,015,000.

The Underwriter is offering the Notes and the Certificates subject to receipt and acceptance by the Underwriter and subject to its right to reject any order in whole or in part. We expect that the Notes and Certificates will be ready for delivery in book-entry form only through The Depository Trust Company in New York, New York on or about December 28, 1999 against payment in immediately available funds and, in the case of the Notes, also through Cedel Bank, societe anonyme, and the Euroclear System.

Neither the SEC nor any state securities commission has approved or disapproved the Notes or Certificates or determined whether this Prospectus Supplement or the Prospectus is accurate or complete. Any representation to the contrary is a criminal offense.

You should consider carefully the risk factors beginning on page S-14 of this Prospectus Supplement and on Page 13 of the Prospectus.

The Certificates represent interests in, and the Notes represent obligations of, the Trust only. They are not interests in or obligations of SLM Holding Corporation, the Seller, Student Loan Marketing Association, the Servicer or any of their affiliates.

Neither the Certificates nor the Notes are guaranteed or insured by the United States of America or any governmental agency.

This Prospectus Supplement may be used to offer and sell the Notes or Certificates only if accompanied by the Prospectus
