Item 5.   Other Events
          ------------

          On July 27, 1998, the Sallie Mae Student Loan Trust 1995-1 made its
eleventh, the Sallie Mae Student Loan Trust 1996-1 made its tenth, the SLM
Student Loan Trust 1996-2 made its ninth, the SLM Student Loan Trust 1996-3 made
its eighth, the SLM Student Loan Trust 1996-4 made its seventh, the SLM Student
Loan Trust 1997-1 made its sixth, the SLM Student Loan Trust 1997-2 made its
fifth, the SLM Student Loan Trust 1997-3 made its fourth, the SLM Student Loan
Trust 1997-4 made its second, and the SLM Student Loan Trust 1998-1 made its
first regular quarterly distribution of funds to holders of their respective
Floating Rate Student Loan-Backed Notes and distributed their respective
Quarterly Servicing Reports, filed herewith as an Exhibit to this Form 8-K, to
Certificateholders and Noteholders of record.

          The Registrant is hereby filing the Quarterly Servicing Reports
reflecting each Trust's activities as of July 27, 1998.

          On July 1, 1998, the Department of Education published a notice in the
Federal Register in which it announced that it reduced current borrower interest
rates on Federal Direct Consolidation Loans for borrowers whose applications for
such loans are processed after July 1, 1998 from 8.25% to 7.46% (6.86% during
in-school, grace and deferment periods), which rates are adjusted annually based
on a formula equal to the 91-day Treasury bill rate plus 2.3 percent (1.7
percent during in-school, grace and deferment periods).  The availability of the
reduced borrower interest rates on Federal Direct Consolidations Loan may
increase the likelihood that a student loan owned by the related trust (each a
"Trust Student Loan") will be prepaid from the proceeds of such loans.  The
volume of Trust Student Loans that may be prepaid in this fashion cannot be
determined at this time and will be affected by, among other things, the
operational limitations on the Department of Education's ability to process a
significant increase in Federal Direct Consolidation Loan volume and the period
during which reduced rates are available.  The Congress is expected to address
the rate on Federal Direct Consolidation Loans as part of the reauthorization of
the Higher Education Act scheduled for this session of Congress.  There can be
no assurance that the Congress will address the rate on consolidation loans,
either as to pending or future applications, or that any legislation adopted
will provide for the same rate on both FFELP and Federal Direct Consolidation
Loans or that any legislated consolidation loan rate will not prompt borrowers
to refinance Trust Student Loans at a level greater than the current level of
such refinancings.

           As of July 27, 1998 the ratio of (1) the principal balance of the 
assets in the Trusts to (2) the aggregate principal amount outstanding of the
Securities of such Trust (the "Parity Ratio")/1/ is as follows :

           Trust                   Parity Ratio
           -----                   ------------
           1995-1                  100%
           1996-1                  100%
           1996-2                  100%
           1996-3                  100%
           1996-4                  100%
           1997-1                  99.3%
           1997-2                  98.8%
           1997-3                  98.4%
           1997-4                  97.6%
           1998-1                  99.1%
           1998-2                  99.8%/2/

1. The Parity Ratios calculated, which are based on the asset principal 
balances, understate total assets (and, therefore, the true ratio of assets to 
liabilities in the related Trust) as certain accrued interest asset amounts have
not been included in the numerator of the ratio. As of July 27, 1998 there was 
no accrued interest on the Notes and Certificates in the related Trusts.

2. Estimated using Pool Balance as of the Cutoff Date of May 25, 1998 and 
Reserve Account and Collection Account balances and Securities principal
amounts as of the Closing Date of June 18, 1998 since the first Distribution
Date is October 26, 1998.

Until the Parity Ratio reaches 100%, the Securityholders must rely primarily on
interest and subsidy payments on the Trust Student Loans and interest on other
Trust assets in excess of Servicing Fees, Administration Fees and interest
payable on the Securities to reduce the aggregate principal amount of the
Securities to an amount equal to the principal amount of the Trust's assets. To
the extent that Securityholders are so reliant, the Securityholders could be
adversely affected by a significant increase in the rate of prepayments.
