            Legislative Developments

            On February 1, 1999, President Clinton submitted his Fiscal Year
2000 budget proposal to Congress. The budget proposes significant savings from
the student loan programs, principally from the FFELP. Among the proposals for
student loans are the following:

o     Reinstatement of a lower rate for new Federal Direct Consolidation Loans.
      This variable rate (the 91-day Treasury bill rate plus 2.3 during
      repayment and 1.7% during in-school and grace periods) would apply for
      borrowers whose applications are received before September 30, 2000. The
      budget proposals would also lower the annual fee paid by lenders on FFELP
      consolidation loans made during the same period from 1.05 percent to .62
      percent of the principal plus accrued unpaid interest;

o     Creation of a 90-day period during which interest on a highly delinquent
      FFELP loan does not accrue. The Reauthorization Legislation extended the
      period before lenders can submit default claims from 180 days to 270 days;
      the budget proposes to eliminate interest accrual during this extended
      period;

o     Reduction by 30 basis points of special allowance payments on FFELP loans
      funded with tax exempt securities; and

o     Implementation of additional Guarantor reforms, including the acceleration
      of recall of Guarantor reserves mandated by the Reauthorization
      Legislation, recall of an additional $1.5 billion in reserves, the
      reduction of the Guarantor retention rate on payments on defaulted loans
      to 18.5 percent, the reduction in the share of the remaining amount that
      Guarantors may retain, and an expansion of the use of voluntary flexible
      agreements authorized by the Reauthorization Legislation.

            Budget resolutions for the FY 2000 budget passed by both houses of
Congress failed to include any of these proposals.

Item 5. (continued)

            REGULATORY DEVELOPMENTS

            In the first quarter of 1999, each of the four principal banking 
regulators - the Board of Governors of the Federal Reserve System, the Office 
of the Comptroller of the Currency, the Office of Thrift Supervision and the 
Federal Deposit Insurance Corporation - responded favorably to the 
Registrant's request for an interpretation and clarification of the existing 
risk-based capital standards governing the institutions they regulate with 
respect to the appropriate risk-weighting of the senior student loan-backed 
securities issued by the Trusts.  Specifically, each of the banking 
regulators agreed that the senior student loan-backed securities issued by 
the Trusts may be assigned to the 20 percent risk category rather than the 
100 percent risk category to the extent that the student loans underlying 
such securities are guaranteed by the U.S. Department of Education.  In 
accordance with the two percent lender risk sharing provisions of the Higher 
Education Act, 98 percent of such senior securities that are backed in whole 
or in part by federally guaranteed student loans that were disbursed on or 
after October 1, 1993 would be eligible for assignment to the 20 percent risk 
category.  Management believes that, as a result of these clarifications, 
regulated depository institutions that hold senior student loan-backed 
securities issued by the Trusts may be able to retain less capital on a 
regulatory basis.

            This Current Report on Form 8-K contains forward-looking 
statements that are based on management's current expections as of the date 
of this document.  When used herein, the words "anticipate," 
"believe,""estimate" and "expect" and similar expressions, as they relate to 
the Company's management, are intended to identify forward-looking 
statements. Such forward-looking statements are subject to risks, 
uncertainties, assumptions and other factors that may cause the actual 
results of the Registrant to be materially different from those reflected in 
such forward-looking statements.  Such factors include, among others, changes 
in the applicable laws and regulations; changes in the general interest rate 
environment and in the securitization markets for student loans; and 
interruptions of others' operations resulting from the inability of computer 
or other systems to process Year 2000-related information.
